The value of the Nutrition and Obesity Policy Research and Evaluation Network in advancing the evidence base for effective nutrition and obesity policy: assessment using the Consolidated Framework for Collaborative Research
Vasquez T , Levi R , Akers M , Lowry-Warnock A , Blanck HM , Seligman H . BMC Public Health 2023 23 (1) 375 INTRODUCTION: Addressing nutrition disparities and preventing obesity require multi-level interventions, including policies that address the nutrition environment and other social determinants of health. The Nutrition and Obesity Policy Research Evaluation Network (NOPREN) was established in 2009 to conduct transdisciplinary research and accelerate the translation and implementation of science-based policy interventions. This study examined NOPREN's collaborative practices and identified opportunities to improve network impact. METHODS: Using a mixed-methods approach, we combined quantitative survey data (n = 106) and in-depth, qualitative interviews (n = 18) to evaluate the experiences of NOPREN members and understand the extent to which NOPREN was achieving its goals. RESULTS: Using the Consolidated Framework for Collaborative Research (CFCR), quantitative and qualitative results were organized into 11 themes. We find that NOPREN's structure and standardized processes facilitate connections to individuals and resources, foster relationships, and support effective cross-sector collaborations. Areas of improvement include capacity building and a more intentional approach towards recruitment of a diverse membership. CONCLUSION: A collaborative research network can build synergy across sectors and accelerate knowledge transfer. These findings will be used to inform the network's strategic priorities to maximize impact. Findings may also inform similar collaborative efforts for addressing complex public health problems. |
Supporting healthy weight in statewide Quality Rating and Improvement Systems: A review of 2020 standards and comparison to 2015 standards
Hall K , Geary N , Warnock AL , Dooyema C . Child Obes 2022 Background: Quality Rating and Improvement Systems (QRISs) are used to assess, improve, and communicate quality in early care and education (ECE) programs. One strategy for supporting healthy growth in early childhood is embedding nutrition, physical activity, infant feeding, and screen time content into state QRIS standards, using the Caring for Our Children high-impact obesity prevention standards (HIOPS) and the CDC Spectrum of Opportunities framework (CDC Spectrum). We assessed the number of obesity prevention standards in QRISs in 2020 and compared results to an analysis published in 2015. Methods: We collected state QRIS standards for ECE centers from March to April 2020. Two analysts coded documents for standards related to 47 HIOPS and 6 Spectrum areas. Results: Thirty-nine states and the District of Columbia had statewide QRISs in early 2020. Of these, 21 QRISs (53%) embedded 1 or more HIOPS, and 26 (65%) embedded 1 or more Spectrum components. On average, 6.9% of HIOPS were embedded in QRIS standards in 2020, an increase from 4.6% in 2015. Nine QRISs included more HIOPS in 2020 than in 2015. Five QRISs added 10% or more of the 47 HIOPS between 2015 and 2020. Physical activity and screen time standards continued to be most often included; infant feeding standards were least included. Conclusion: Obesity prevention components were embedded in three-quarters of state QRISs, and more were embedded in 2020 than in 2015, suggesting that QRISs can be levers for supporting healthy weight in ECE settings. |
Leveraging federal, state, and facility-level early care and education systems and providers toward optimal child nutrition in the first 1000 days
Dooyema CA , Hall K , Tovar A , Bauer KW , Lowry-Warnock A , Blanck HM . Am J Public Health 2022 112 S779-s784 Early childhood is a critical period in the development, growth, and health of children. Many infants and toddlers in the United States spend time in nonparental early care and education (ECE) arrangements, which include care from child-care centers, family child-care homes, family members, and neighbors, or a combination of these providers. As of 2019, 14% of infants (0–12 months of age) and 27% of toddlers (1–2 years) participated in a center-based care arrangement; however, these statistics do not account for children cared for in family child-care homes, which are also an important source of care for this age group.1 |
Advancing healthy food service in the United States: State food service guidelines policy adoption and implementation supports, 2015-2019
Lowry-Warnock A , Strombom N , Mugavero K , Harris D , Blanck HM , Onufrak S . Am J Health Promot 2022 37 (3) 8901171221123311 PURPOSE: Food service guidelines (FSG) policies can impact the nutritional quality of millions of meals sold or served to government employees, citizens in public places, or institutionalized persons. This study examines state FSG policies adopted January 1, 2015 to April 1, 2019, and uses a FSG Classification Tool (FSG Tool) to quantify alignment with nutrition recommendations for public health impact. DESIGN: Quantitative Content Analysis. SETTING: State Government Worksites and Facilities. PARTICIPANTS: 50 states and District of Columbia (D.C.) in the United States. MEASURES: Frequency of policies and percent alignment to FSG tool. ANALYSIS: FSG policies were identified using legal databases to assess state statutes, regulations, and executive orders. Content analysis and coding determined attributes of policies across 4 FSG Tool domains, (1) nutrition standards referenced; (2) behavioral design strategies encouraging selection of healthier offerings; (3) facility efficiency and environmental sustainability; and (4) FSG implementation supports. RESULTS: From 2015-2019, 5 FSG policies met study inclusion criteria. Four out of 5 policies earned a perfect nutrition score (100%) by referencing nutrition standards that align with the Dietary Guidelines for Americans (DGA) and are operationalized for use in food service venues. Four out of 5 policies included at least 1 implementation supports provision, such as naming an implementing agency, and 2 included provisions that encourage local food sourcing. CONCLUSION: From 2015-2019, overall FSG policy comprehensiveness scores ranged from 24% to 73%, with most policies referencing food and nutrition standards that align to national nutrition recommendations. Public health practitioners can educate decision makers on the potential impact of FSG policies on diet-related health outcomes and associated cost savings, as well as other important co-benefits that support locally grown products and environmental sustainability practices. |
Prevalence of Municipal-Level Policies Dedicated to Transportation That Consider Food Access
Dumas BL , Harris DM , McMahon JM , Daymude TJ , Warnock AL , Moore LV , Onufrak SJ . Prev Chronic Dis 2021 18 E97 INTRODUCTION: Local governments can address access to healthy food and transportation through policy and planning. This study is the first to examine municipal-level transportation supports for food access. METHODS: We used a nationally representative sample of US municipalities with 1,000 or more persons from the 2014 National Survey of Community-Based Policy and Environmental Supports for Healthy Eating and Active Living (N = 2,029) to assess 3 outcomes: public transit availability, consideration of food access in transportation planning, and presence of demand-responsive transportation (DRT). We used χ(2) tests to compare prevalences by municipal characteristics including population size, rurality, census region, median educational attainment, poverty prevalence, racial and ethnic population distribution, and low-income low-access to food (LILA) status. RESULTS: Among municipalities, 33.7% reported no public transit and 14.8% reported having DRT. Both public transit and DRT differed by population size (both P < .001) and census region (both P < .001) and were least commonly reported among municipalities with populations less than 2,500 (46.9% without public transit; 6.6% with DRT) and in the South (40.0% without public transit; 11.1% with DRT). Of those with public transit, 33.8% considered food access in transportation planning; this was more common with greater population size (55.9% among municipalities of ≥50,000 persons vs 16.8% among municipalities of <2,500 persons; P < .001), in the West (43.1% vs 26.8% in the Northeast, 33.7% in the Midwest, 32.2% in the South; P = .003), and municipalities with 20% or more of the population living below federal poverty guidelines (37.4% vs 32.2% among municipalities with less than 20% living in poverty; P = .07). CONCLUSION: Results suggest that opportunities exist to improve food access through transportation, especially in smaller and Southern communities, which may improve diet quality and reduce chronic disease. |
A healthy start: National trends in child care regulations and uptake of obesity prevention standards (2010-2018)
Warnock AL , Dooyema C , Blanck HM , Lee SH , Hall K , Geary N , Galuska DA . Child Obes 2021 17 (3) 176-184 Background: Obesity remains a significant public health issue in the United States. Each week, millions of infants and children are cared for in early care and education (ECE) programs, making it an important setting for building healthy habits. Since 2010, 39 states promulgated licensing regulations impacting infant feeding, nutrition, physical activity, or screen time practices. We assessed trends in ECE regulations across all 50 states and the District of Columbia (D.C.) and hypothesized that states included more obesity prevention standards over time. Methods: We analyzed published ratings of state licensing regulations (2010-2018) and describe trends in uptake of 47 high-impact standards derived from Caring for Our Children's, Preventing Childhood Obesity special collection. National trends are described by (1) care type (Centers, Large Care Homes, and Small Care Homes); (2) state and U.S. region; and (3) most and least supported standards. Results: Center regulations included the most obesity prevention standards (∼13% in 2010 vs. ∼29% in 2018) compared with other care types, and infant feeding and nutrition standards were most often included, while physical activity and screen time were least supported. Some states saw significant improvements in uptake, with six states and D.C. having a 30%-point increase 2010-2018. Conclusions: Nationally, there were consistent increases in the percentage of obesity prevention standards included in ECE licensing regulations. Future studies may examine facilitators and barriers to the uptake of obesity prevention standards and identify pathways by which public health and health care professionals can act as a resource and promote obesity prevention in ECE. |
Associations between food policy councils and policies that support healthy food access: A national survey of community policy supports
Lange SJ , Calancie L , Onufrak SJ , Reddy KT , Palmer A , Warnock AL . Nutrients 2021 13 (2) 1-13 Food policy councils (FPCs) are one form of community coalition that aims to address challenges to local food systems and enhance availability, accessibility, and affordability of healthy foods for local residents. We used data from the 2014 National Survey of Community-Based Policy and Environmental Supports for Healthy Eating and Active Living, a nationally representative survey of US municipalities (n = 2029), to examine the prevalence of FPCs and cross-sectional associations between FPCs and four types of supports for healthy food access (approaches to help food stores, practices to support farmers markets, transportation-related supports, and community planning documents). Overall, 7.7% of municipalities reported having a local or regional FPC. FPCs were more commonly reported among larger municipalities with ≥50,000 people (29.2%, 95% Confidence Interval (CI): 21.6, 36.8) and western region municipalities (13.2%, 95% CI: 9.6, 16.8). After multivariable adjustment, municipalities with FPCs had significantly higher odds of having all four types of supports, compared to those without FPCs (adjusted odds ratio (aOR) range: 2.4–3.4). Among municipalities with FPCs (n = 156), 41% reported having a local government employee or elected official as a member, and 46% had a designated health or public health representative. Although FPCs were uncommon, municipalities that reported having a local or regional FPC were more likely to report having supports for healthy food access for their residents. |
Best practices for financial sustainability of healthy food service guidelines in hospital cafeterias
Jilcott Pitts S , Schwartz B , Graham J , Warnock AL , Mojica A , Marziale E , Harris D . Prev Chronic Dis 2018 15 E58 In February and March 2017 we examined barriers and facilitators to financial sustainability of healthy food service guidelines and synthesized best practices for financial sustainability in retail operations. We conducted qualitative, in-depth interviews with 8 hospital food service directors to learn more about barriers and facilitators to financial sustainability of healthy food service guidelines in retail food service operations. Analysts organized themes around headers in the interview guide and also made note of emerging themes not in the original guide. They used the code occurrence and co-occurrence features in Dedoose version 7.0.23 (SocioCultural Research Consultants) independently to analyze patterns across the interviews and to pull illustrative quotes for analysis. Two overarching themes emerged, related to 1) the demand for and sales of healthy foods and beverages, and 2) the production and supply of healthy foods and beverages. Our study provides insights into how hospital food service directors can maximize revenue and remain financially viable while selling healthier options in on-site dining facilities. |
The Childhood Obesity Declines Project: A review of enacted policies
Dooyema C , Jernigan J , Warnock AL , Dawkins-Lyn N , Harris C , Kauh T , Kettel Khan L , Ottley P , Young-Hyman D . Child Obes 2018 14 S22-s31 BACKGROUND: State- and local-level policies can influence children's diet quality and physical activity (PA) behaviors. The goal of this article is to understand the enacted state and local policy landscape in four communities reporting declines in childhood obesity. METHODS AND RESULTS: State-level policies were searched within the CDC's online Chronic Disease State Policy Tracking System. Local level policies were captured during key informant interviews in each of the sites. Policies were coded by setting [i.e., early care and education (ECE) also known as child care, school, community], jurisdictional level (i.e., state or local) and policy type (i.e., legislation or regulation). The time period for each site was unique, capturing enacted policies 5 years before the reported declines in childhood obesity in each of the communities. A total of 39 policies were captured across the 4 sites. The majority originated at the state level. Two policies pertaining to ECE, documented during key informant interviews, were found to be adopted at the local level. CONCLUSION: Similarities were noted between the four communities in the types of polices enacted. All four communities had state- and/or local-level policies that aimed to improve the nutrition environment and increase opportunities for PA in both the ECE and K-12 school settings. This article is a step in the process of determining what may have contributed to obesity declines in the selected communities. |
A single center, open label study of intradermal administration of an inactivated purified chick embryo cell culture rabies virus vaccine in adults
Recuenco S , Warnock E , Osinubi MOV , Rupprecht CE . Vaccine 2017 35 (34) 4315-4320 In the USA, rabies vaccines (RVs) are licensed for intramuscular (IM) use only, although RVs are licensed for use by the intradermal (ID) route in many other countries. Recent limitations in supplies of RV in the USA reopened discussions on the more efficient use of available biologics, including utilization of more stringent risk assessments, and potential ID RV administration. A clinical trial was designed to compare the immunogenic and adverse effects of a purified chicken embryo cell (PCEC) RV administered ID or IM. Enrollment was designed in four arms, ID Pre-Exposure Prophylaxis (Pre-EP), IM Pre-EP, ID Booster, and IM Booster vaccination. Enrollment included 130 adult volunteers. The arms with IM administration received vaccine according to the current ACIP recommendations: Pre-EP, three 1mL (2.5 I.U.) RV doses, each on day 0, 7, and 21; or a routine Booster, one 1ml dose. The ID groups received the same schedule, but doses administered were in a volume of 0.1mL (0.25 I.U.). The rate of increase in rabies virus neutralizing antibody titers 14-21days after vaccination were similar in the ID and correspondent IM groups. The GMT values for ID vaccination were slightly lower than those for IM vaccination, for both naive and booster groups, and these differences were statistically significant by t-test. Fourteen days after completing vaccination, all individuals developed RV neutralizing antibody titers over the minimum arbitrary value obtained with the rapid fluorescent focus inhibition test (RFFIT). Antibodies were over the set threshold until the end of the trial, 160days after completed vaccination. No serious adverse reactions were reported. Most frequent adverse reactions were erythema, induration and tenderness, localized at the site of injection. Multi use of 1mL rabies vaccine vials for ID doses of 0.1 was demonstrated to be both safe and inmunogenic. |
Pneumococcal vaccination among Medicare beneficiaries occurring after the Advisory Committee On Immunization Practices Recommendation for routine use of 13-valent pneumococcal conjugate vaccine and 23-valent pneumococcal polysaccharide vaccine for adults aged ≥65 years
Black CL , Williams WW , Warnock R , Pilishvili T , Kim D , Kelman JA . MMWR Morb Mortal Wkly Rep 2017 66 (27) 728-733 On September 19, 2014, CDC published the Advisory Committee on Immunization Practices (ACIP) recommendation for the routine use of 13-valent pneumococcal conjugate vaccine (PCV13) among adults aged ≥65 years, to be used in series with 23-valent pneumococcal polysaccharide vaccine (PPSV23) (1). This replaced the previous recommendation that adults aged ≥65 years should be vaccinated with a single dose of PPSV23. As a proxy for estimating PCV13 and PPSV23 vaccination coverage among adults aged ≥65 years before and after implementation of these revised recommendations, CDC analyzed claims for vaccination submitted for reimbursement to the Centers for Medicare & Medicaid Services (CMS). Claims from any time during a beneficiary's enrollment in Medicare Parts A (hospital insurance) and B (medical insurance) since reaching age 65 years were assessed among beneficiaries continuously enrolled in Medicare Parts A and B during annual periods from September 19, 2009, through September 18, 2016. By September 18, 2016, 43.2% of Medicare beneficiaries aged ≥65 years had claims for at least 1 dose of PPSV23 (regardless of PCV13 status), 31.5% had claims for at least 1 dose of PCV13 (regardless of PPSV23 status), and 18.3% had claims for at least 1 dose each of PCV13 and PPSV23. Claims for either type of pneumococcal vaccine were highest among beneficiaries who were older, white, or with chronic and immunocompromising medical conditions than among healthy adults. Implementation of the National Vaccine Advisory Committee's standards for adult immunization practice to assess vaccination status at every patient encounter, recommend needed vaccines, and administer vaccination or refer to a vaccinating provider might help increase pneumococcal vaccination coverage and reduce the risk for pneumonia and invasive pneumococcal disease among older adults (2). |
Food service guideline policies on state government-controlled properties
Zaganjor H , Bishop Kendrick K , Warnock AL , Onufrak S , Whitsel LP , Ralston Aoki J , Kimmons J . Am J Health Promot 2016 32 (6) 1340-1352 PURPOSE: Food service guideline (FSG) policies can impact millions of daily meals sold or provided to government employees, patrons, and institutionalized persons. This study describes a classification tool to assess FSG policy attributes and uses it to rate FSG policies. DESIGN: Quantitative content analysis. SETTING: State government facilities in the United States. PARTICIPANTS: Participants were from 50 states and District of Columbia in the United States. MEASURES: Frequency of FSG policies and percentage alignment to tool. ANALYSIS: State-level policies were identified using legal research databases to assess bills, statutes, regulations, and executive orders proposed or adopted by December 31, 2014. Full-text reviews were conducted to determine inclusion. Included policies were analyzed to assess attributes related to nutrition, behavioral supports, and implementation guidance. RESULTS: A total of 31 policies met the inclusion criteria; 15 were adopted. Overall alignment ranged from 0% to 86%, and only 10 policies aligned with a majority of the FSG policy attributes. Western states had the most FSG policies proposed or adopted (11 policies). The greatest number of FSG policies were proposed or adopted (8 policies) in 2011, followed by the years 2013 and 2014. CONCLUSION: The FSG policies proposed or adopted through 2014 that intended to improve the food and beverage environment on state government property vary considerably in their content. This analysis offers baseline data on the FSG landscape and information for future FSG policy assessments. |
Demographic trends of sick leave absenteeism among civil service employees at a federal agency from 2004 to 2012
Gajewski K , Burris D , Spears DR , Sullivan K , Oyinloye O , McNeil C , Meechan P , Warnock E , Trapp J , Decker KC , Chapman S . J Occup Environ Med 2015 57 (3) 277-83 OBJECTIVE: To investigate the associations between demographic variables and sick leave use. METHODS: We analyzed sick leave use among civil servants at a federal agency (FA) from 2004 to 2012 by demographic and FA-specific variables. We used a mixed methods approach and type III analysis to build a descriptive model of sick leave proportions and demographic variables. RESULTS: Sick absenteeism usage varied significantly (variation of greater than one sick day per year) by sex, Emergency Operations Center response tier, length of service at the FA, age, and general schedule pay grade level. Our final descriptive model contained age, sex, response tier and an interaction term between age and sex. CONCLUSIONS: Future studies should examine these associations on smaller time scales, perhaps breaking the data down by month or day of the week. |
Predicting temporal trends in total absenteeism rates for civil service employees of a federal public health agency
Spears DR , McNeil C , Warnock E , Trapp J , Oyinloye O , Whitehurst V , Decker KC , Chapman S , Campbell M , Meechan P . J Occup Environ Med 2014 56 (6) 632-8 OBJECTIVE: This study evaluates the predictability in temporal absences trends due to all causes (total absenteeism) among employees at a federal agency. The objective is to determine how leave trends vary within the year, and determine whether trends are predictable. METHODS: Ten years of absenteeism data from an attendance system were analyzed for rates of total absence. RESULTS: Trends over a 10-year period followed predictable and regular patterns during a given year that correspond to major holiday periods. Temporal trends in leave among small, medium, and large facilities compared favorably with the agency as a whole. CONCLUSIONS: Temporal trends in total absenteeism rates for an organization can be determined using its attendance system. The ability to predict employee absenteeism rates can be extremely helpful for management in optimizing business performance and ensuring that an organization meets its mission. |
Health risks, travel preparation, and illness among public health professionals during international travel
Balaban V , Warnock E , Ramana Dhara V , Jean-Louis LA , Sotir MJ , Kozarsky P . Travel Med Infect Dis 2014 12 (4) 349-54 BACKGROUND: Few data currently exist on health risks faced by public health professionals (PHP) during international travel. We conducted pre- and post-travel health surveys to assess knowledge, attitudes, and practices (KAP), and illnesses among PHP international travelers. METHOD: Anonymous surveys were completed by PHP from a large American public health agency who sought a pre-travel medical consult from September 1, 2009, to September 30, 2010. RESULTS: Surveys were completed by 122 participants; travelers went to 163 countries. Of the 122 respondents, 97 (80%) reported at least one planned health risk activity (visiting rural areas, handling animals, contact with blood or body fluids, visiting malarious areas), and 50 (41%) reported exposure to unanticipated health risks. Of the 62 travelers who visited malarious areas, 14 (23%) reported inconsistent or no use of malaria prophylaxis. Illness during travel was reported by 33 (27%) respondents. CONCLUSIONS: Most of the PHP travelers in our study reported at least one planned health risk activity, and almost half reported exposure to unanticipated health risks, and one-quarter of travelers to malarious areas reported inconsistent or no use of malaria chemoprophylaxis. Our findings highlight that communication and education outreach for PHP to prevent travel-associated illnesses can be improved. |
Predicting temporal trends in sickness absence rates for civil service employees of a federal public health agency
Spears DR , McNeil C , Warnock E , Trapp J , Oyinloye O , Whitehurst V , Decker KC , Chapman S , Campbell M , Meechan P . J Occup Environ Med 2012 55 (2) 179-90 OBJECTIVE: To determine whether trends of sickness in employees at a federal agency are predictable, and whether the variance was minimal enough to detect unusual levels of employee illness for further investigation. METHODS: Ten years of absenteeism data from an attendance system were analyzed for rates of sickness absence. Specifically, week of year and day of week were used to describe temporal trends. RESULTS: This study evaluates the predictability in temporal absence trends due to sickness among employees at a federal agency. Trends follow regular patterns during a given year that correspond to seasonal illnesses. Temporal trends in sick leave have been proven to be very predictable. CONCLUSION: The minimal variance allows the detection of sick leave anomalies that may be ascribable to specific causes, allowing the business or agency to follow-up and develop interventions. |
ELISpot detection of mumps-specific antibody secreting B-cells as an alternative method of laboratory diagnosis
Latner DR , McGrew M , Williams N , Lowe L , Werman R , Warnock E , Gallagher K , Doyle P , Smole S , Lett S , Cocoros N , Demaria A , Konomi R , Brown CJ , Rota PA , Bellini WJ , Hickman CJ . Clin Vaccine Immunol 2010 18 (1) 35-42 Although high measles, mumps, and rubella (MMR) vaccination coverage has been successful in dramatically reducing mumps disease in the United States, mumps (re)infections occasionally occur in individuals who have been either previously vaccinated or naturally infected. Standard diagnostics that detect virus or virus-specific antibody are dependable for confirming primary mumps infection in immunologically naive persons, but these methods perform inconsistently on individuals with prior immune exposure. We hypothesized that detection of activated mumps-specific Antibody-Secreting B-Cells (ASC) by ELISpot could be used as a more reliable diagnostic. To test this, a time-course of virus-specific ASC responses was measured by ELISpot following MMR vaccination of 16 previously vaccinated or naturally exposed adult volunteers. Mumps-specific ASC were detectable in 68% of these individuals at some point during the first 3 weeks following re-vaccination. In addition, mumps-specific ASC were detected in 7/7 previously vaccinated individuals who recently had been infected as part of a confirmed mumps outbreak. These data suggest that ELISpot detection of mumps-specific ASC has the potential for use as an alternative method of diagnosis when suspect cases cannot be confirmed by detection of IgM or virus. In addition, it was determined that mumps-specific memory B-cells are detected at a much lower frequency than measles or rubella-specific cells, suggesting that mumps infection may not generate robust B-cell memory. |
