County-level cardiac rehabilitation and broadband availability: Opportunities for hybrid care in the United States
DeLara DL , Pollack LM , Wall HK , Chang A , Schieb L , Matthews K , Stolp H , Pack QR , Casper M , Jackson SL . J Cardiopulm Rehabil Prev 2024 PURPOSE: Cardiac rehabilitation (CR) improves patient outcomes and quality of life and can be provided virtually through hybrid CR. However, little is known about CR availability in conjunction with broadband access, a requirement for hybrid CR. This study examined the intersection of CR and broadband availability at the county level, nationwide. METHODS: Data were gathered and analyzed in 2022 from the 2019 American Community Survey, the Centers for Medicare & Medicaid Services, and the Federal Communications Commission. Spatially adaptive floating catchments were used to calculate county-level percent CR availability among Medicare fee-for-service beneficiaries. Counties were categorized: by CR availability, whether lowest (ie, CR deserts), medium, or highest; and by broadband availability, whether CR deserts with majority-available broadband, or dual deserts. Results were stratified by state. County-level characteristics were examined for statistical significance by CR availability category. RESULTS: Almost half of US adults (n = 116 325 976, 47.2%) lived in CR desert counties (1691 counties). Among adults in CR desert counties, 96.8% were in CR deserts with majority-available broadband (112 626 906). By state, the percentage of the adult population living in CR desert counties ranged from 3.2% (New Hampshire) to 100% (Hawaii and Washington, DC). Statistically significant differences in county CR availability existed by race/ethnicity, education, and income. CONCLUSIONS: Almost half of US adults live in CR deserts. Given that up to 97% of adults living in CR deserts may have broadband access, implementation of hybrid CR programs that include a telehealth component could expand CR availability to as many as 113 million US adults. |
Association of economic policies with hypertension management and control: A systematic review
Zhang D , Lee JS , Pollack LM , Dong X , Taliano JM , Rajan A , Therrien NL , Jackson SL , Popoola A , Luo F . JAMA Health Forum 2024 5 (2) e235231 IMPORTANCE: Economic policies have the potential to impact management and control of hypertension. OBJECTIVES: To review the evidence on the association between economic policies and hypertension management and control among adults with hypertension in the US. EVIDENCE REVIEW: A search was carried out of PubMed/MEDLINE, Cochrane Library, Embase, PsycINFO, CINAHL, EconLit, Sociological Abstracts, and Scopus from January 1, 2000, through November 1, 2023. Included were randomized clinical trials, difference-in-differences, and interrupted time series studies that evaluated the association of economic policies with hypertension management. Economic policies were grouped into 3 categories: insurance coverage expansion such as Medicaid expansion, cost sharing in health care such as increased drug copayments, and financial incentives for quality such as pay-for-performance. Antihypertensive treatment was measured as taking antihypertensive medications or medication adherence among those who have a hypertension diagnosis; and hypertension control, measured as blood pressure (BP) lower than 140/90 mm Hg or a reduction in BP. Evidence was extracted and synthesized through dual review of titles, abstracts, full-text articles, study quality, and policy effects. FINDINGS: In total, 31 articles were included. None of the studies examined economic policies outside of the health care system. Of these, 16 (52%) assessed policies for insurance coverage expansion, 8 (26%) evaluated policies related to patient cost sharing for prescription drugs, and 7 (22%) evaluated financial incentive programs for improving health care quality. Of the 16 studies that evaluated coverage expansion policies, all but 1 found that policies such as Medicare Part D and Medicaid expansion were associated with significant improvement in antihypertensive treatment and BP control. Among the 8 studies that examined patient cost sharing, 4 found that measures such as prior authorization and increased copayments were associated with decreased adherence to antihypertensive medication. Finally, all 7 studies evaluating financial incentives aimed at improving quality found that they were associated with improved antihypertensive treatment and BP control. Overall, most studies had a moderate or low risk of bias in their policy evaluation. CONCLUSIONS AND RELEVANCE: The findings of this systematic review suggest that economic policies aimed at expanding insurance coverage or improving health care quality successfully improved medication use and BP control among US adults with hypertension. Future research is needed to investigate the potential effects of non-health care economic policies on hypertension control. |
Racial and ethnic differences in hypertension-related telehealth and in-person outpatient visits before and during the COVID-19 pandemic among Medicaid Beneficiaries
Lee JS , Bhatt A , Pollack LM , Jackson SL , Omeaku N , Lowe Beasley K , Wilson C , Luo F , Roy K . Telemed J E Health 2024 Background: Little is known about the trends and costs of hypertension management through telehealth among individuals enrolled in Medicaid. Methods: Using MarketScan(®) Medicaid database, we examined outpatient visits among people with hypertension aged 18-64 years. We presented the numbers of hypertension-related telehealth and in-person outpatient visits per 100 individuals and the proportion of hypertension-related telehealth outpatient visits to total outpatient visits by month, overall, and by race and ethnicity. For the cost analysis, we presented total and patient out-of-pocket (OOP) costs per visit for telehealth and in-person visits in 2021. Results: Of the 229,562 individuals, 114,445 (49.9%) were non-Hispanic White, 80,692 (35.2%) were non-Hispanic Black, 3,924 (1.71%) were Hispanic. From February to April 2020, the number of hypertension-related telehealth outpatient visits per 100 persons increased from 0.01 to 6.13, the number of hypertension-related in-person visits decreased from 61.88 to 52.63, and the proportion of hypertension-related telehealth outpatient visits increased from 0.01% to 10.44%. During that same time, the proportion increased from 0.02% to 13.9% for non-Hispanic White adults, from 0.00% to 7.58% for non-Hispanic Black adults, and from 0.12% to 19.82% for Hispanic adults. The average total and patient OOP costs per visit in 2021 were $83.82 (95% confidence interval [CI], 82.66-85.05) and $0.55 (95% CI, 0.42-0.68) for telehealth and $264.48 (95% CI, 258.87-269.51) and $0.72 (95% CI, 0.65-0.79) for in-person visits, respectively. Conclusions: Hypertension management via telehealth increased among Medicaid recipients regardless of race and ethnicity, during the COVID-19 pandemic. These findings may inform telehealth policymakers and health care practitioners. |
Rural and urban differences in hypertension management through telehealth before and during the COVID-19 pandemic among commercially insured patients
Lee JS , Bhatt A , Jackson SL , Pollack LM , Omeaku N , Lowe K , Wilson C , Luo F , Roy K . Am J Hypertens 2023 BACKGROUND: The COVID-19 pandemic prompted a rapid increase in telehealth use. However, limited evidence exists on how rural and urban residents used telehealth and in-person outpatient services to manage hypertension during the pandemic. METHODS: This longitudinal study analyzed 701,410 US adults (18-64 years) in the MarketScan Commercial Claims Database, who were continuously enrolled from January 2017 through March 2022. We documented monthly numbers of hypertension-related telehealth and in-person outpatient visits (per 100 individuals), and the proportion of telehealth visits among all hypertension-related outpatient visits, from January 2019 through March 2022. We used Welch's 2-tail t-test to differentiate monthly estimates by rural-urban status and month-to-month changes. RESULTS: From February through April 2020, the monthly number of hypertension-related telehealth visits per 100 individuals increased from 0.01 to 6.05 (P<0.001) for urban residents and from 0.01 to 4.56 (P<0.001) for rural residents. Hypertension-related in-person visits decreased from 20.12 to 8.30 (P<0.001) for urban residents and from 20.48 to 10.15 (P<0.001) for rural residents. The proportion of hypertension-related telehealth visits increased from 0.04% to 42.15% (P<0.001) for urban residents and from 0.06% to 30.98% (P<0.001) for rural residents. From March 2020 to March 2022, the monthly average of the proportions of hypertension-related telehealth visits was higher for urban residents than for rural residents (10.19% vs. 6.96%; P<0.001). CONCLUSIONS: Data show that rural residents were less likely to use telehealth for hypertension management. Understanding trends in hypertension-related telehealth utilization can highlight disparities in the sustained use of telehealth to advance accessible health care. |
HIV risk behavior profiles among men who have sex with men interested in donating blood: Findings from the Assessing Donor Variability and New Concepts in Eligibility study
Custer B , Whitaker BI , Pollack LM , Buccheri R , Bruhn RL , Crowder LA , Stramer SL , Reik RA , Pandey S , Stone M , Di Germanio C , Buchacz K , Eder AF , Lu Y , Forshee RA , Anderson SA , Marks PW . Transfusion 2023 63 (10) 1872-1884 BACKGROUND: Individual risk assessment allows donors to be evaluated based on their own behaviors. Study objectives were to assess human immunodeficiency virus (HIV) risk behaviors in men who have sex with men (MSM) and estimate the proportion of the study population who would not be deferred for higher risk HIV sexual behaviors. STUDY DESIGN AND METHODS: Cross-sectional survey and biomarker assessment were conducted in eight U.S. cities. Participants were sexually active MSM interested in blood donation aged 18-39 years, assigned male sex at birth. Participants completed surveys during two study visits to define eligibility, and self-reported sexual and HIV prevention behaviors. Blood was drawn at study visit 1 and tested for HIV and the presence of tenofovir, one of the drugs in oral HIV pre-exposure prophylaxis (PrEP). Associations were assessed between HIV infection status or HIV PrEP use and behaviors, including sex partners, new partners, and anal sex. RESULTS: A total of 1566 MSM completed the visit 1 questionnaire and blood draw and 1197 completed the visit 2 questionnaire. Among 1562 persons without HIV, 789 (50.4%) were not taking PrEP. Of those not taking PrEP, 66.2% reported one sexual partner or no anal sex and 69% reported no new sexual partners or no anal sex with a new partner in the past 3 months. CONCLUSION: The study found that questions were able to identify sexually active, HIV-negative MSM who report lower risk sexual behaviors. About a quarter of enrolled study participants would be potentially eligible blood donors using individual risk assessment questions. |
Rural/urban differences in health care utilization and costs by perinatal depression status among commercial enrollees
Pollack LM , Chen J , Cox S , Luo F , Robbins CL , Tevendale H , Li R , Ko JY . J Rural Health 2023 40 (1) 26-63 PURPOSE: To understand differences in health care utilization and medical expenditures by perinatal depression (PND) status during pregnancy and 1-year postpartum overall and by rural/urban status. METHODS: We estimated differences in health care utilization and medical expenditures by PND status for individuals with an inpatient live-birth delivery in 2017, continuously enrolled in commercial insurance from 3 months before pregnancy through 1-year postpartum (study period), using MarketScan Commercial Claims data. Multivariable regression was used to examine differences by rurality. FINDINGS: Ten percent of commercially insured individuals had claims with PND. A smaller proportion of rural (8.7%) versus urban residents (10.0%) had a depression diagnosis (p < 0.0001). Of those with PND, a smaller proportion of rural (5.5%) versus urban residents (9.6%) had a depression claim 3 months before pregnancy (p < 0.0001). Compared with urban residents, rural residents had greater differences by PND status in total inpatient days (rural: 0.7, 95% confidence interval [CI]: 0.6-0.9 vs. urban: 0.5, 95% CI: 0.5-0.6) and emergency department (ED) visits (rural: 0.7, 95% CI: 0.6-0.9 vs. urban: 0.5, 95% CI: 0.4-0.5), but a smaller difference by PND status in the number of outpatient visits (rural: 9.2, 95% CI: 8.2-10.2 vs. urban: 13.1, 95% CI: 12.7-13.5). Differences in expenditures for inpatient services by PND status differed by rural/urban status (rural: $2654; 95% CI: $1823-$3485 vs. urban: $1786; 95% CI: $1445-$2127). CONCLUSIONS: Commercially insured rural residents had more utilization for inpatient and ED services and less utilization for outpatient services. Rural locations can present barriers to evidence-based care to address PND. |
HIV Risk Behavior Profiles Among Men Who Have Sex with Men Interested in Donating Blood: The Assessing Donor Variability and New Concepts in Eligibility (ADVANCE) Study (preprint)
Custer B , Whitaker B , Pollack L , Buccheri R , Bruhn R , Crowder L , Stramer SL , Reik R , Pandey S , Stone M , Di Germanio C , Buchacz K , Eder A , Lu Y , Forshee R , Anderson S , Marks P . medRxiv 2023 09 Importance: Blood donor selection policies should be evidence-based. Individual risk assessment allows potential donors to be evaluated based on their own behaviors. Objective(s): The Assessing Donor Variability and New Concepts in Eligibility (ADVANCE) study examined behavioral and biomarkers of HIV risk in sexually active men who have sex with men (MSM) to estimate the proportion of the study population who would not be deferred for higher risk HIV sexual behaviors and might be eligible to donate. Design(s): A cross-sectional assessment of sexually active MSM interested in blood donation. Setting(s): An 8-city study of MSM aged 18 - 39 years assigned male sex at birth. Interventions or Exposures: Participants completed surveys during 2 study visits to define eligibility, self-reported sexual and HIV prevention behaviors. Blood was drawn at study visit 1 and tested for HIV and the presence of tenofovir, 1 of the drugs in oral HIV pre-exposure prophylaxis (PrEP). Main Outcomes and Measures: Associations between HIV infection status or HIV PrEP use and self-reported HIV risk behaviors, including number of male sex partners, new partners, and anal sex. Result(s): Among 1788 screened MSM, 1593 were eligible and 1566 completed the visit 1 HIV risk questionnaire and blood draw. A median of 22 days later, 1197 completed the visit 2 follow-up questionnaire. Four individuals tested HIV positive (0.25%). Among HIV-negative participants, 789 (50.4%) reported no PrEP use in the past 3 months. The number of sex partners in the past 3 months was significantly higher among PrEP users versus non-users, as was the number reporting a new male sex partner in the same period. Among HIV-negative, non-PrEP using participants, 66.2% reported only 1 sexual partner or no anal sex and 69% reported no new sexual partners or no anal sex with a new partner in the past 3 months. Conclusion and Relevance: Among sexually active MSM, there are subgroups who self-report no new sexual partners and only 1 sexual partner within the past 3 months. These individuals are likely at lower risk of HIV infection than other MSM and would meet proposed individual risk assessment criteria for blood donation in the U.S. Copyright The copyright holder for this preprint is the author/funder, who has granted medRxiv a license to display the preprint in perpetuity.

Timing of outpatient postpartum care utilization among women with chronic hypertension and hypertensive disorders of pregnancy
Aqua JK , Ford ND , Pollack LM , Lee JS , Kuklina EV , Hayes DK , Vaughan AS , Coronado F . Am J Obstet Gynecol MFM 2023 5 (9) 101051 BACKGROUND: The postpartum period represents an opportunity to assess the cardiovascular health of women who experience chronic hypertension or hypertensive disorders of pregnancy. OBJECTIVES: To determine whether women with chronic hypertension or hypertensive disorders of pregnancy access outpatient postpartum care more quickly compared to women with no hypertension. STUDY DESIGN: We used data from the Merative MarketScan® Commercial Claims and Encounters Database. We included 275,937 commercially insured women aged 12-55 years who had a live birth or stillbirth delivery hospitalization between 2017-2018 and continuous insurance enrollment from 3 months before the estimated start of pregnancy to 6 months after delivery discharge. Using International Classification of Diseases 10th Revision Clinical Modification codes, we identified hypertensive disorders of pregnancy from inpatient or outpatient claims from 20 weeks gestation through delivery hospitalization and identified chronic hypertension from inpatient or outpatient claims from the beginning of the continuous enrollment period through delivery hospitalization. Distributions of time-to-event survival curves (time-to-first outpatient postpartum visit with a women's health, primary care, or cardiology provider) were compared between the hypertension types using Kaplan-Meier estimators and log rank tests. We used Cox proportional hazards models to estimate adjusted hazard ratios (aHR) and 95% confidence intervals (CI). Time points of interest (3, 6, and 12 weeks) were evaluated per clinical postpartum care guidelines. RESULTS: Among commercially insured women, the prevalences of hypertensive disorders of pregnancy, chronic hypertension, and no documented hypertension were 11.7%, 3.4%, and 84.8%, respectively. The proportions of women with a visit within 3 weeks of delivery discharge were 28.5%, 26.4%, and 16.0% for hypertensive disorders of pregnancy, chronic, and no documented hypertension, respectively. By 12 weeks, the proportions increased to 62.4%, 64.5%, and 54.2%, respectively. Kaplan-Meier analyses indicated significant differences in utilization by hypertension type and interaction between hypertension type and time before and after 6 weeks. In adjusted Cox proportional hazards models, the utilization rate before 6 weeks among women with hypertensive disorders of pregnancy was 1.42 times the rate for women with no documented hypertension [aHR=1.42, 95% CI (1.39-1.45)]. Women with chronic hypertension also had higher utilization rates compared to women with no documented hypertension before 6 weeks [aHR=1.28, 95% CI: (1.24-1.33)]. Only chronic hypertension was significantly associated with utilization compared to the no documented hypertension group after 6 weeks [aHR=1.09, 95% CI: (1.03-1.14)]. CONCLUSIONS: In the 6 weeks following delivery discharge, women with hypertensive disorders of pregnancy and chronic hypertension attended outpatient postpartum care visits sooner than women with no documented hypertension. However, after 6 weeks this difference extended only to women with chronic hypertension. Overall, postpartum care utilization remained around 50-60% by 12 weeks in all groups. Addressing barriers to postpartum care attendance can ensure timely care for women at high risk for cardiovascular disease. |
Breast and colorectal cancer recurrence-free survival estimates in the US: Modeling versus active data collection
Mariotto AB , Thompson TD , Johnson C , Wu XC , Pollack LA . Cancer Epidemiol 2023 85 102370 BACKGROUND: A modeling method was developed to estimate recurrence-free survival using cancer registry survival data. This study aims to validate the modeled recurrence-free survival against "gold-standard" estimates from data collected by the National Program of Cancer Registries (NPCR) Patient-Centered Outcomes Research (PCOR) project. METHODS: We compared 5-year metastatic recurrence-free survival using modeling and empirical estimates from the PCOR project that collected disease-free status, tumor progression and recurrence for colorectal and female breast cancer cases diagnosed in 2011 in 5 U.S. state registries. To estimate empirical recurrence-free survival, we developed an algorithm that combined disease-free, recurrence, progression, and date information from NPCR-PCOR data. We applied the modeling method to relative survival for patients diagnosed with female breast and colorectal cancer in 2000-2015 in the SEER-18 areas. RESULTS: When grouping patients with stages I-III, the 5-year metastatic recurrence-free modeled and NPCR-PCOR estimates are very similar being respectively, 90.2 % and 88.6 % for female breast cancer, 74.6 % and 75.3 % for colon cancer, and 68.8 % and 68.5 % for rectum cancer. In general, the 5-year recurrence-free NPCR-PCOR and modeled estimates are still similar when controlling by stage. The modeled estimates, however, are not as accurate for recurrence-free survival in years 1-3 from diagnosis. CONCLUSIONS: The alignment between NPCR-PCOR and modeled estimates supports their validity and provides robust population-based estimates of 5-year metastatic recurrence-free survival for female breast, colon, and rectum cancers. The modeling approach can in principle be extended to other cancer sites to provide provisional population-based estimates of 5-year recurrence free survival. |
A pretest-posttest design to assess the effectiveness of an intervention to reduce HIV-related stigma and discrimination in healthcare settings in Vietnam
Pollack TM , Duong HT , Nhat Vinh DT , Phuong DT , Thuy DH , Nhung VTT , Uyen NK , Linh VT , Van Truong N , Le Ai KA , Ninh NT , Nguyen A , Canh HD , Cosimi LA . J Int AIDS Soc 2022 25 Suppl 1 e25932 INTRODUCTION: Stigma and discrimination are important barriers to HIV epidemic control. We implemented a multi-pronged facility-level intervention to reduce stigma and discrimination at health facilities across three high-burden provinces. Key components of the intervention included measurement of stigma, data review and use, participatory training of healthcare workers (HCWs), and engagement of people living with HIV and key populations in all stigma reduction activities. METHODS: From July 2018 to July 2019, we assessed HIV-related stigma and discrimination among patients and HCWs at 10 facilities at baseline and 9 months following an intervention. A repeated measures design was used to assess the change in stigma and discrimination among HCWs and a repeated cross-sectional design assessed the change in stigma and discrimination experienced by PLHIV. HCWs at target facilities were invited at random and PLHIV were recruited when presenting for care during the two assessment periods. McNemar's test was used to compare paired proportions among HCWs, and chi-square test was used to compare proportions among PLHIV. Mixed models were used to compare outcomes before and after the intervention. RESULTS: Semi-structured interviews were conducted with 649 and 652 PLHIV prior to and following the intervention, respectively. At baseline, over the previous 12 months, 21% reported experiencing discrimination, 16% reported self-stigma, 14% reported HIV disclosure without consent and 7% had received discriminatory reproductive health advice. Nine months after the intervention, there was a decrease in reported stigma and discrimination across all domains to 15%, 11%, 7% and 3.5%, respectively (all p-values <0.05). Among HCWs, 672 completed the pre- and post-intervention assessment. At baseline, 81% reported fear of HIV infection, 69% reported using unnecessary precautions when caring for PLHIV, 44% reported having observed other staff discriminate against PLHIV, 54% reported negative attitudes towards PLHIV and 41% felt uncomfortable working with colleagues living with HIV. The proportions decreased after the intervention to 52%, 34%, 32%, 35% and 24%, respectively (all p-values <0.05). CONCLUSIONS: A multi-pronged facility-level intervention was successful at reducing healthcare-associated HIV-related stigma in Vietnam. The findings support the scale-up of this intervention in Vietnam and highlight key components potentially applicable in other settings. |
Pulmonary and Critical Care Considerations for e-Cigarette, or Vaping, Product Use-Associated Lung Injury.
Hayes DJr , Board A , Calfee C , Ellington S , Pollack LA , Kathuria H , Eakin MN , Weissman DN , Callahan SJ , Esper AM , Crotty Alexander LE , Sharma NS , Meyer NJ , Smith LS , Novosad S , Evans ME , Goodman AB , Click ES , Robinson RT , Ewart G , Twentyman E . Chest 2022 162 (1) 256-264 BACKGROUND: In 2019, the United States experienced a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI). More than half of these patients required admission to an intensive care unit (ICU). METHODS: To synthesize information critical to pulmonary/critical care specialists in the care of patients with EVALI, we examined data available from patients hospitalized with EVALI between August 2019 and January 2020; reviewed the clinical course and critical care experience with those patients admitted to the ICU; and compiled opinion of national experts. RESULTS: Of the 2,708 confirmed or probable EVALI patients requiring hospitalization as of January 21, 2020, 1,604 (59.2%) had data available on ICU admission; of these, 705 (44.0%) were admitted to the ICU and are included in this analysis. The majority of ICU patients required respiratory support (88.5%), and in severe cases required intubation (36.1%), or extracorporeal membrane oxygenation (ECMO) (6.7%). The majority (93.0%) of these ICU patients survived to discharge. Review of the clinical course and expert opinion provided insight into: imaging; considerations for bronchoscopy; medical treatment, including use of empiric antibiotics, antivirals, and corticosteroids; respiratory support, including considerations for intubation, positioning maneuvers, and ECMO; and patient outcomes. CONCLUSIONS: Review of the clinical course of EVALI patients requiring ICU admission and compilation of expert opinion provided critical insight into pulmonary/critical care-specific considerations for this patient population. As a large proportion of patients hospitalized with EVALI required ICU admission, it is important to remain prepared to care for patients with EVALI. |
Healthcare utilization and costs associated with perinatal depression among Medicaid enrollees
Pollack LM , Chen J , Cox S , Luo F , Robbins CL , Tevendale HD , Li R , Ko JY . Am J Prev Med 2022 62 (6) e333-e341 INTRODUCTION: Differences in healthcare utilization and medical expenditures associated with perinatal depression are estimated. METHODS: Using the MarketScan Multi-State Medicaid Database, the analytic cohort included individuals aged 15-44 years who had an inpatient live birth delivery hospitalization between January 1, 2017 and December 31, 2018. Multivariable negative binomial regression models were used to estimate the differences in utilization associated with perinatal depression, and multivariable generalized linear models were used to estimate the differences in expenditures associated with perinatal depression. Analyses were conducted in 2021. RESULTS: The cohort included 330,593 individuals. Nearly 17% had perinatal depression. Compared with individuals without perinatal depression individuals with perinatal depression had a larger number of inpatient admissions (0.19, 95% CI=0.18, 0.20), total inpatient days (0.95, 95% CI=0.92, 0.97), outpatient visits (14.02, 95% CI=13.81, 14.22), emergency department visits (1.70, 95% CI=1.66, 1.74), and weeks of drug therapy covered by a prescription (28.70, 95% CI=28.12, 29.28) and larger total expenditures ($5,078, 95% CI=$4,816, $5,340). Non-Hispanic Black individuals had larger differences in utilization and expenditures for inpatient services and outpatient visits but smaller differences in utilization for pharmaceutical services associated with perinatal depression than non-Hispanic White individuals. Hispanic individuals had larger differences in utilization for outpatient visits but smaller differences in utilization for pharmaceutical services associated with perinatal depression than non-Hispanic White individuals. CONCLUSIONS: Individuals with perinatal depression had more healthcare utilization and medical expenditures than individuals without perinatal depression, and differences varied by race/ethnicity. The findings highlight the need to ensure comprehensive and equitable mental health care to address perinatal depression. |
Systematic review on quantifying pedestrian injury when evaluating changes to the built environment
Pollack Porter KM , Omura JD , Ballard RM , Peterson EL , Carlson SA . Prev Med Rep 2022 26 101703 Modifying the built environment to make communities more walkable remains one strategy to promote physical activity. These modifications may have the added benefit of reducing the risk of pedestrian injury; however, there is a gap in the physical activity literature regarding how best to measure pedestrian injury. Examining the measures that have been used and related data sources can help inform the use of pedestrian injury data to evaluate whether safety is optimized as walking increases. We conducted a systematic review of the literature to identify studies that evaluated changes to the built environment that support walking and measures impacts on pedestrian injury as a measure of safety. We searched PubMed, PsycInfo, and Web of Science to identify peer-review studies and websites of fifteen organizations to document studies from the grey literature published in English between January 1, 2010 and December 31, 2018. Our search identified twelve studies that met the inclusion criteria. The few studies that measured changes in pedestrian injury used crash data from police reports. Injury frequency was often reported, but not injury severity, and no studies reported injury risk based on walking exposure. We conclude that few studies have measured pedestrian injury in the context of creating more walkable communities. Future research would benefit from using well-characterized measures from existing studies to support consistency in measurement, and from more longitudinal and evaluation research to strengthen the evidence on additional benefits of walkability. Increased collaborations with injury prevention professionals could bolster use of valid and reliable measures. |
Impact of Relative Dose Intensity of FOLFOX Adjuvant Chemotherapy on Risk of Death Among Stage III Colon Cancer Patients
Zhou M , Thompson TD , Lin HY , Chen VW , Karlitz JJ , Fontham ETH , Theall KP , Zhang L , Hsieh MC , Pollack LA , Wu XC . Clin Colorectal Cancer 2021 21 (2) e62-e75 BACKGROUND: The National Comprehensive Cancer Network (NCCN) guidelines have recommended tailored chemotherapy for stage III high-risk (T4 and/or N2) and low-risk (T1-T3 and N1) colon cancer since 2018. Studies have investigated the effect of relative dose intensity (RDI) of FOLFOX on stage III colon cancer survival, however, none has performed a stratified analysis by risk profiles. This study aims to identify the FOLFOX optimal RDI for high-risk and low-risk stage III colon cancer patients. METHODS: Data on 407 eligible patients, diagnosed with stage III colon cancer in 2011 who received FOLFOX, were collected by 8 population-based cancer registries. Multivariable Cox model and Fine-Gray competing risks model were employed to explore Optimal RDI defined as the lowest RDI administered without significant differences in either overall or cause-specific death. RESULTS: Among the 168 high-risk patients, the optimal RDI cut-off was 70% (HR = 1.59 with 95% CI: 0.69-3.66 in overall mortality; HR = 1.24 with 95% CI: 0.42-3.64 in cause-specific mortality when RDI < 70% vs. RDI ≥ 70%). Among the 239 low-risk patients, none of the evaluated cut-offs were associated with significant differences in risk of death between comparison groups. The lowest assessed RDI was 45%, HR = 0.80; 95% CI: 0.24 to 2.73 for overall mortality and HR = 0.53; 95% CI: 0.06 to 4.95 for cause-specific mortality, when RDI <45% versus RDI ≥45%. CONCLUSIONS: There is no significant harm on the risk of death when reducing RDI by <30% for high-risk patients. For the low-risk patients, we found that RDI as low as 45% did not significantly affect the risk of death. |
Biomonitoring of volatile organic compounds (VOCs) among hairdressers in salons primarily serving women of color: A pilot study
Louis LM , Kavi LK , Boyle M , Pool W , Bhandari D , De Jesús VR , Thomas S , Pollack AZ , Sun A , McLean S , Rule AM , Quirós-Alcalá L . Environ Int 2021 154 106655 Hairdressers are exposed to volatile organic compounds (VOCs), many of which have been linked to acute and chronic health effects. Those hairdressers serving an ethnic clientele may potentially experience disproportionate exposures from frequent use of products containing VOCs or different VOC concentrations contained in products which are marketed to the specific needs of their clientele. However, no biomonitoring studies have investigated occupational exposures in this population. In the present pilot study, we sought to characterize concentrations and exposure determinants for 28 VOC biomarkers in post-shift urine samples among 23 hairdressers primarily serving an ethnic clientele. VOC biomarker concentrations among hairdressers of color were compared to concentrations among a comparison group of 17 office workers and a representative sample of women participating in the U.S. National Health and Nutrition Examination Survey. VOC biomarkers were detected in all hairdressers with higher concentrations observed among hairdressers serving a predominantly Black versus Latino clientele, and among hairdressers overall versus office workers and women in the U.S. general population. Median biomarker concentrations for acrolein,1,3-butadiene, and xylene in hairdressers were more than twice as high as those observed among office workers. Median concentrations for 1-bromopropane, acrolein and 1,3-butadiene were more than four times higher among all hairdressers compared to those reported among women in the U.S. general population. Select salon services (e.g., sister locs, flat ironing, permanent hair coloring, permanent waves or texturizing, Brazilian blowout or keratin treatment, etc.) were also associated with higher VOC biomarker concentrations among hairdressers. This pilot study represents the first biomonitoring analysis to characterize VOC exposures among women hairdressers of color and to provide evidence that this occupational population may experience elevated VOC exposures compared to women in the U.S. general population. Results from our study represent an important first step in elucidating occupational VOC exposures in this understudied occupational group. Larger studies among a racially and ethnically diverse cohort of hairdressers are warranted to confirm our findings and inform future exposure interventions in this understudied occupational population. |

Population heath informatics can advance interoperability: National Program of Cancer Registries Electronic Pathology Reporting Project
Pollack LA , Jones SF , Blumenthal W , Alimi TO , Jones DE , Rogers JD , Benard VB , Richardson LC . JCO Clin Cancer Inform 2020 4 985-992 PURPOSE: Given the reach, breadth, and volume of data collected from multiple clinical settings and systems, US central cancer registries (CCRs) are uniquely positioned to test and advance cancer health information exchange. This article describes a current Centers for Disease Control and Prevention (CDC) National Program of Cancer Registries (NPCR) cancer informatics data exchange initiative. METHODS: CDC is using an established cloud-based platform developed by the Association of Public Health Laboratories (APHL) for national notifiable disease reporting to enable direct transmission of standardized electronic pathology (ePath) data from laboratories to CCRs in multiple states. RESULTS: The APHL Informatics Messaging Services (AIMS) Platform provides an infrastructure to enable a large national laboratory to submit data to a single platform. State health departments receive data from the AIMS Platform through a secure portal, eliminating separate data exchange routes with each CCR. CONCLUSION: Key factors enabling ePath data exchange from laboratories to CCRs are having established cancer registry data standards and using a single platform/portal to reduce data streams. NPCR plans to expand this approach in alignment with ongoing cancer informatics efforts in clinical settings. The 50 CCRs supported by NPCR provide a variety of scenarios to develop and disseminate cancer data informatics initiatives and have tremendous potential to increase the implementation of cancer data exchange. |

Adkins SH , Anderson KN , Goodman AB , Twentyman E , Danielson ML , Kimball A , Click ES , Ko JY , Evans ME , Weissman DN , Melstrom P , Kiernan E , Krishnasamy V , Rose DA , Jones CM , King BA , Ellington SR , Pollack LA , Wiltz JL . JAMA Pediatr 2020 174 (7) e200756 Importance: To date, limited information is available on the characteristics of adolescents with e-cigarette, or vaping, product use-associated lung injury (EVALI). Objective: To inform public health and clinical practice by describing differences in demographics, substance use behaviors, and clinical characteristics of EVALI among adolescents compared with adults. Design, Setting, and Participants: Surveillance data reported to the Centers for Disease Control and Prevention during the 2019 EVALI outbreak were used to calculate adjusted prevalence ratios (aPRs) with 95% CIs and to test differences between 360 hospitalized or deceased adolescents vs 859 young adults and 936 adults with EVALI (N = 2155). Main Outcomes and Measures: Demographics, substance use behaviors, and clinical characteristics. Results: Included in this cross-sectional study were 360 hospitalized or deceased adolescents (age range, 13-17 years; 67.9% male) vs 859 young adults (age range, 18-24 years; 72.4% male) and 936 adults (age range, 25-49 years; 65.6% male) with EVALI. Adolescents diagnosed as having EVALI reported using any nicotine-containing (62.4%), any tetrahydrocannabinol (THC)-containing (81.7%), and both (50.8%) types of e-cigarette or vaping products. Informal sources for obtaining nicotine-containing and THC-containing e-cigarette or vaping products were more commonly reported by adolescents (50.5% for nicotine and 96.5% for THC) than young adults (19.8% for nicotine [aPR, 2.49; 95% CI, 1.78-3.46] and 86.9% for THC [aPR, 1.11; 95% CI, 1.05-1.18]) or adults (24.3% for nicotine [aPR, 2.06; 95% CI, 1.49-2.84] and 75.1% for THC [aPR, 1.29; 95% CI, 1.19-1.40]). Mental, emotional, or behavioral disorders were commonly reported; a history of attention-deficit/hyperactivity disorder was almost 4 times more likely among adolescents (18.1%) than adults (4.9%) (aPR, 3.74; 95% CI, 1.92-7.26). A history of asthma was more likely to be reported among adolescents (43.6%) than adults (28.3%) (aPR, 1.53; 95% CI, 1.14-2.05). Gastrointestinal and constitutional symptoms were more common in adolescents (90.9% and 97.3%, respectively) than adults (75.3% and 94.5%, respectively) (aPR, 1.20; 95% CI, 1.13-1.28 and aPR, 1.03; 95% CI, 1.00-1.06, respectively). Because of missing data, percentages may not be able to be calculated from data provided. Conclusions and Relevance: Public health and clinical professionals should continue to provide information to adolescents about the association between EVALI and THC-containing e-cigarette or vaping product use, especially those products obtained through informal sources, and that the use of any e-cigarette or vaping product is unsafe. Compared with adults, it appears that adolescents with EVALI more frequently have a history of asthma and mental, emotional, or behavioral disorders, such as attention-deficit/hyperactivity disorder, and report nonspecific problems, including gastrointestinal and constitutional symptoms; therefore, obtaining a confidential substance use history that includes e-cigarette or vaping product use is recommended. |
Estimating the impact of increasing cervical cancer screening in the National Breast and Cervical Cancer Early Detection Program among low-income women in the USA
Pollack LM , Ekwueme DU , Hung MC , Miller JW , Chang SH . Cancer Causes Control 2020 31 (7) 691-702 PURPOSE: The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides free cervical cancer screening to low-income women. This study estimated the health benefits gained in terms of life years (LYs) saved and quality-adjusted life years (QALYs) gained if cervical cancer screening by the NBCCEDP increased to reach more eligible women. METHODS: Data from Surveillance, Epidemiology, and End Results, NBCCEDP, and Medical Expenditure Panel Surveys were used. LYs saved and QALYs gained/100,000 women were estimated using modeling methods. They were used to predict additional health benefits gained if screening by the NBCCEDP increased from 6.5% up to 10-25% of the eligible women. RESULTS: Overall, per 100,000 women screened by the NBCCEDP, 1,731 LYs were saved and 1,608 QALYs were gained. For white women, 1,926 LYs were saved and 1,780 QALYs were gained/100,000 women screened by the NBCCEDP. For black women, 1,506 LYs were saved and 1,300 QALYs were gained/100,000 women screened. If the proportion of eligible women screened by the NBCCEDP increased to 10-25%, the estimated health benefits would range from 6,626-34,896 LYs saved and 6,153-32,407 QALYs gained. CONCLUSIONS: The reported estimates emphasize the value of cervical cancer screening program by extending LE in low-income women. Further, it demonstrates that screening a higher percentage of eligible women in the NBCCEDP may yield more health benefits. |

BMJ Glob Health 2020 5 (4) e002166 Development of a robust technical assistance system is an essential component of a sustainable HIV response. Vietnam's National HIV Program is transitioning from a largely donor-funded programme to one primarily supported by domestic resources. Telehealth interventions are increasingly being used for training, mentoring and expert consultation in high-resource settings and hold significant potential for use as a tool to build HIV health worker capacity in low and middle-income countries. We designed, implemented and scaled up a novel HIV telehealth programme for Vietnam, with the goal of building a sustainable training model to support the country's HIV workforce needs. Over a 4-year period, HIV telehealth programmes were initiated in 17 public institutions with participation of nearly 700 clinical sites across 62 of the 63 provinces in the country. The telehealth programme was used to deliver certificate training courses, provide clinical mentoring and case-based learning, support programme implementation, provide coaching in quality improvement and disseminate new guidelines and policies. Programme evaluation demonstrated improved health worker self-reported competence in HIV care and treatment and high satisfaction among the programme participants. Lessons learnt from Vietnam's experience with telehealth can inform country programmes looking to develop a sustainable approach to HIV technical assistance and health worker capacity building. |
Prevalence of cigarette smoking among patients with different histological types of kidney cancer
Gansler T , Fedewa SA , Flanders WD , Pollack LA , Siegel DA , Jemal A . Cancer Epidemiol Biomarkers Prev 2020 29 (7) 1406-1412 BACKGROUND: Cigarette smoking is causally linked to renal cell carcinoma (RCC). However, associations for individual RCC histologies are not well-described. Newly-available data on tobacco use from population-based cancer registries allow characterization of associations with individual RCC types. METHODS: We analyzed data for 30,282 RCC cases from 8 states that collected tobacco use information for a National Program of Cancer Registry project. We compared the prevalence and adjusted prevalence ratios (aPR) of cigarette smoking (current vs never, former vs never) among individuals diagnosed between 2011 and 2016 with clear cell RCC, papillary RCC, chromophobe RCC, renal collecting duct/medullary carcinoma, cyst-associated RCC, and unclassified RCC. RESULTS: Of 30,282 RCC patients, 50.2% were current or former cigarette smokers. By histology, proportions of current or formers smokers ranged from 38% in patients with chromophobe carcinoma to 61.9% in those with collecting duct/medullary carcinoma. The aPRs (with the most common histology, clear cell RCC, as referent group) for current and former cigarette smoking among chromophobe RCC cases (4.9% of our analytic sample) were 0.58 (95% CI, 0.50-0.67) and 0.88 (95% CI, 0.81-0.95), respectively. Other aPRs were slightly increased (papillary RCC and unclassified RCC, current smoking only), slightly decreased (unclassified RCC, former smoking only) or not significantly different from 1.0 (collecting duct/medullary carcinoma and cyst-associated RCC). CONCLUSIONS: Compared with other RCC histological types, chromophobe RCC has a weaker (if any) association with smoking. IMPACT: This study shows the value of population-based cancer registries' collection of smoking data, especially for epidemiological investigation of rare cancers. |
Update: Characteristics of a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury - United States, August 2019-January 2020
Krishnasamy VP , Hallowell BD , Ko JY , Board A , Hartnett KP , Salvatore PP , Danielson M , Kite-Powell A , Twentyman E , Kim L , Cyrus A , Wallace M , Melstrom P , Haag B , King BA , Briss P , Jones CM , Pollack LA , Ellington S . MMWR Morb Mortal Wkly Rep 2020 69 (3) 90-94 Since August 2019, CDC, the Food and Drug Administration (FDA), state and local health departments, and public health and clinical stakeholders have been investigating a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). This report updates patient demographic characteristics, self-reported substance use, and hospitalization dates for EVALI patients reported to CDC by states, as well as the distribution of emergency department (ED) visits related to e-cigarette, or vaping, products analyzed through the National Syndromic Surveillance Program (NSSP). As of January 14, 2020, a total of 2,668 hospitalized EVALI cases had been reported to CDC. Median patient age was 24 years, and 66% were male. Overall, 82% of EVALI patients reported using any tetrahydrocannabinol (THC)-containing e-cigarette, or vaping, product (including 33% with exclusive THC-containing product use), and 57% of EVALI patients reported using any nicotine-containing product (including 14% with exclusive nicotine-containing product use). Syndromic surveillance indicates that ED visits related to e-cigarette, or vaping, products continue to decline after sharply increasing in August 2019 and peaking in September 2019. Clinicians and public health practitioners should remain vigilant for new EVALI cases. CDC recommends that persons not use THC-containing e-cigarette, or vaping, products, especially those acquired from informal sources such as friends, family members, or from in-person or online dealers. Vitamin E acetate is strongly linked to the EVALI outbreak and should not be added to any e-cigarette, or vaping, products (2). However, evidence is not sufficient to rule out the contribution of other chemicals of concern, including chemicals in either THC- or non-THC-containing products, in some reported EVALI cases. |
Breast and colorectal cancer recurrence and progression captured by five U.S. population-based registries: Findings from National Program of Cancer Registries patient-centered outcome research
Thompson TD , Pollack LA , Johnson CJ , Wu XC , Rees JR , Hsieh MC , Rycroft R , Culp M , Wilson R , Wu M , Zhang K , Benard V . Cancer Epidemiol 2020 64 101653 OBJECTIVES: Cancer recurrence is a meaningful patient outcome that is not captured in population-based cancer surveillance. This project supported National Program of Cancer Registries central cancer registries in five U.S. states to determine the disease course of all breast and colorectal cancer cases. The aims were to assess the feasibility of capturing disease-free (DF) status and subsequent cancer outcomes and to explore analytic approaches for future studies. METHODS: Data were obtained on 11,769 breast and 6033 colorectal cancer cancers diagnosed in 2011. Registry-trained abstractors reviewed medical records from multiple sources for up to 60 months to determine documented DF status, recurrence, progression and residual disease. We described the occurrence of these patient-centered outcomes along with analytic considerations when determining time-to-event outcomes and recurrence-free survival. RESULTS: Disease-free status was determined on all but 3.8 % of cancer cases. Among 14,458 cases that became DF, 6.1 % of breast and 13.0 % of colorectal cancer cases had a documented recurrence. Recurrence-free survival varied by stage; for stage II-III cancers at 48 months, 83.2 % of female breast and 69.2 % of colorectal cancer patients were alive without recurrence. The ability to distinguish between progression and residual disease among never disease-free patients limited our ability to examine progression as an outcome. CONCLUSIONS: This study demonstrated that population-based registries given intense support and resources can capture recurrence and offer a generalizable picture of cancer outcomes. Further work on refining definitions, sampling strategies, and novel approaches to capture recurrence could advance the ability of a national cancer surveillance system to contribute to patient-centered outcomes research. |
Update: Product, substance-use, and demographic characteristics of hospitalized patients in a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury - United States, August 2019-January 2020
Ellington S , Salvatore PP , Ko J , Danielson M , Kim L , Cyrus A , Wallace M , Board A , Krishnasamy V , King BA , Rose D , Jones CM , Pollack LA . MMWR Morb Mortal Wkly Rep 2020 69 (2) 44-49 CDC, the Food and Drug Administration (FDA), state and local health departments, and public health and clinical stakeholders continue to investigate a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). EVALI patients in Illinois, Utah, and Wisconsin acquired tetrahydrocannabinol (THC)-containing products primarily from informal sources (2,3). This report updates demographic characteristics and self-reported sources of THC- and nicotine-containing e-cigarette, or vaping, products derived from EVALI patient data reported to CDC by state health departments. As of January 7, 2020, among 1,979 (76%) patients with available data on substance use, a total of 1,620 (82%) reported using any THC-containing products, including 665 (34%) who reported exclusive THC-containing product use. Use of any nicotine-containing products was reported by 1,128 (57%) patients, including 264 (13%) who reported exclusive nicotine-containing product use. Among 809 (50%) patients reporting data on the source of THC-containing products, 131 (16%) reported acquiring their products from only commercial sources (i.e., recreational dispensaries, medical dispensaries, or both; vape or smoke shops; stores; and pop-up shops), 627 (78%) from only informal sources (i.e., friends, family, in-person or online dealers, or other sources), and 51 (6%) from both types of sources. Among 613 (54%) EVALI patients reporting nicotine-containing product use with available data on product source, 421 (69%) reported acquiring their products from only commercial sources, 103 (17%) from only informal sources, and 89 (15%) from both types of sources. Adolescents aged 13-17 years were more likely to acquire both THC- and nicotine-containing products from informal sources than were persons in older age groups. The high prevalence of acquisition of THC-containing products from informal sources by EVALI patients reinforces CDC's recommendation to not use e-cigarette, or vaping, products that contain THC, especially those acquired from informal sources. Although acquisition of nicotine-containing products through informal sources was not common overall, it was common among persons aged <18 years. While the investigation continues, CDC recommends that the best way for persons to ensure that they are not at risk is to consider refraining from the use of all e-cigarette, or vaping, products. |
Update: Interim guidance for health care professionals evaluating and caring for patients with suspected e-cigarette, or vaping, product use-associated lung injury and for reducing the risk for rehospitalization and death following hospital discharge - United States, December 2019
Evans ME , Twentyman E , Click ES , Goodman AB , Weissman DN , Kiernan E , Hocevar SA , Mikosz CA , Danielson M , Anderson KN , Ellington S , Lozier MJ , Pollack LA , Rose DA , Krishnasamy V , Jones CM , Briss P , King BA , Wiltz JL . MMWR Morb Mortal Wkly Rep 2020 68 (5152) 1189-1194 What is already known on this topic? In a recent examination of rehospitalization and death among previously hospitalized patients with e-cigarette or vaping, product use–associated lung injury (EVALI), at least one quarter of rehospitalizations and deaths occurred within 2 days of discharge; comorbidities were common among patients who were rehospitalized or who died after discharge. What is added by this report? Updated guidance recommends posthospitalization outpatient follow-up, optimally within 48 hours of discharge, and emphasizes the importance of preparation for hospital discharge and postdischarge care coordination to reduce risk of rehospitalization and death among hospitalized EVALI patients. What are the implications for public health practice? Incorporating this updated guidance into the management of hospitalized EVALI patients might reduce EVALI-associated morbidity and mortality. © 2020 Department of Health and Human Services.

Characteristics of patients experiencing rehospitalization or death after hospital discharge in a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury - United States, 2019
Mikosz CA , Danielson M , Anderson KN , Pollack LA , Currie DW , Njai R , Evans ME , Goodman AB , Twentyman E , Wiltz JL , Rose DA , Krishnasamy V , King BA , Jones CM , Briss P , Lozier M , Ellington S . MMWR Morb Mortal Wkly Rep 2020 68 (5152) 1183-1188 Summary What is already known about this topic? Some patients hospitalized for e-cigarette, or vaping, product use–associated lung injury (EVALI) have been rehospitalized or have died after hospital discharge. What is added by this report? Compared with other EVALI patients, rehospitalized patients and patients who died after hospital discharge were more likely to have one or more chronic conditions, including cardiac disease, chronic pulmonary disease, and diabetes, and to be older. At least one quarter of rehospitalizations and deaths occurred within 2 days after discharge. What are the implications for public health practice? Intensive discharge planning, ensuring clinical stability before discharge, optimized case management, and follow-up optimally within 48 hours after hospital discharge might minimize EVALI patients’ risk for rehospitalization and death, especially among patients with chronic conditions. © 2020 Department of Health and Human Services.

Opportunities for employers to support physical activity through policy
Ablah E , Lemon SC , Pronk NP , Wojcik JR , Mukhtar Q , Grossmeier J , Pollack KM , Whitsel LP . Prev Chronic Dis 2019 16 E84 In an effort to improve health and business outcomes, workplaces are supplementing traditional physical activity programs focused on individual behavior change with policies designed to change workplace culture. However, confusion exists about how to define workplace policies. In practice, worksites implement programs, benefit designs, and environmental strategies and describe these as policies. The purpose of this essay is to provide a definition for worksite policy and discuss how policy approaches can support employers’ efforts to promote physical activity. We also describe worksite physical activity policies that employers can adopt and implement. |
Systematic review of how Play Streets impact opportunities for active play, physical activity, neighborhoods, and communities
Umstattd Meyer MR , Bridges CN , Schmid TL , Hecht AA , Pollack Porter KM . BMC Public Health 2019 19 (1) 335 BACKGROUND: Active play and physical activity are important for preventing childhood obesity, building healthy bones and muscles, reducing anxiety and stress, and increasing self-esteem. Unfortunately, safe and accessible play places are often lacking in under-resourced communities. Play Streets (temporary closure of streets) are an understudied intervention that provide safe places for children, adolescents, and their families to actively play. This systematic review examines how Play Streets impact opportunities for children and adolescents to engage in safe active play and physical activity, and for communities and neighborhoods. Methods for evaluating Play Streets were also examined. METHODS: A systematic literature review was conducted in Academic Search Complete, CINHAL, PsycINFO, PubMED, Web of Science, and Google Scholar. Peer-reviewed intervention studies published worldwide were included if they were published in English, through December 2017 and documented free-to-access Play Streets or other temporary spaces that incorporated a designated area for children and/or adolescents to engage in active play. Systematic data extraction documented sample, implementation, and measurement characteristics and outcomes. RESULTS: Of 180 reviewed abstracts, 6 studies met inclusion criteria. Studies were conducted in five different countries (n = 2 in U.S.), using mostly cross-sectional study designs (n = 4). Physical activity outcomes were measured in half of the studies; one used observational and self-report measures, and two used device-based and self-report measures. In general, Play Streets provided safe places for child play, increased sense of community, and when measured, data suggest increased physical activity overall and during Play Streets. CONCLUSIONS: Play Streets can create safe places for children to actively play, with promise of increasing physical activity and strengthening community. Given the popularity of Play Streets and the potential impact for active play, physical activity, and community level benefits, more rigorous evaluations and systematic reporting of Play Streets' evaluations are needed. |
Racial/ethnic differences in the utilization of chemotherapy among stage I-III breast cancer patients, stratified by subtype: Findings from ten National Program of Cancer Registries states
Zhang L , King J , Wu XC , Hsieh MC , Chen VW , Yu Q , Fontham E , Loch M , Pollack LA , Ferguson T . Cancer Epidemiol 2018 58 1-7 BACKGROUND: The study aimed to examine racial/ethnic differences in chemotherapy utilization by breast cancer subtype. METHODS: Data on female non-Hispanic white (NHW), non-Hispanic black (NHB), and Hispanic stage I-III breast cancer patients diagnosed in 2011 were obtained from a project to enhance population-based National Program of Cancer Registry data for Comparative Effectiveness Research. Hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) were used to classify subtypes: HR+/HER2-; HR+/HER2+; HR-/HER2-; and HR-/HER2 + . We used multivariable logistic regression models to examine the association of race/ethnicity with three outcomes: chemotherapy (yes, no), neo-adjuvant chemotherapy (yes, no), and delayed chemotherapy (yes, no). Covariates included patient demographics, tumor characteristics, Charlson Comorbidity Index, other cancer treatment, and participating states/areas. RESULTS: The study included 25,535 patients (72.1% NHW, 13.7% NHB, and 14.2% Hispanics). NHB with HR+/HER2- (adjusted odds ratio [aOR] 1.22, 95% CI 1.04-1.42) and Hispanics with HR-/HER2- (aOR 1.62, 95% CI 1.15-2.28) were more likely to receive chemotherapy than their NHW counterparts. Both NHB and Hispanics were more likely to receive delayed chemotherapy than NHW, and the pattern was consistent across each subtype. No racial/ethnic differences were found in the receipt of neo-adjuvant chemotherapy. CONCLUSIONS: Compared to NHW with the same subtype, NHB with HR+/HER2- and Hispanics with HR-/HER2- have higher odds of using chemotherapy; however, they are more likely to receive delayed chemotherapy, regardless of subtype. Whether the increased chemotherapy use among NHB with HR+/HER2- indicates overtreatment needs further investigation. Interventions to improve the timely chemotherapy among NHB and Hispanics are warranted. |
Policy and practice-relevant youth Physical Activity Research Center agenda
Botchwey N , Floyd MF , Pollack Porter K , Cutter CL , Spoon C , Schmid TL , Conway TL , Hipp JA , Kim AJ , Umstattd Meyer MR , Walker AL , Kauh TJ , Sallis JF . J Phys Act Health 2018 15 (8) 626-634 BACKGROUND: The Physical Activity Research Center developed a research agenda that addresses youth physical activity (PA) and healthy weight, and aligns with the Robert Wood Johnson Foundation's Culture of Health. This paper summarizes prioritized research studies with a focus on youth at higher risk for inactive lifestyles and childhood obesity in urban and rural communities. METHODS: Systematic literature reviews, a survey, and discussions with practitioners and researchers provided guidance on research questions to build evidence and inform effective strategies to promote healthy weight and PA in youth across race, cultural, and economic groups. RESULTS: The research team developed a matrix of potential research questions, identified priority questions, and designed targeted studies to address some of the priority questions and inform advocacy efforts. The studies selected examine strategies advocating for activity-friendly communities, Play Streets, park use, and PA of youth in the summer. A broader set of research priorities for youth PA is proposed. CONCLUSION: Establishing the Physical Activity Research Center research agenda identified important initial and future research studies to promote and ensure healthy weight and healthy levels of PA for at-risk youth. Results will be disseminated with the goal of promoting equitable access to PA for youth. |
