Building Evidence, Building Community: The Physical Activity Policy Research and Evaluation Network (PAPREN)
Lemon SC , Goins KV , Ussery EN , Rose KM , Chriqui JF . J Healthy Eat Act Living 12/28/2021 1 (4) 165-168 Regular physical activity is an essential action people can take to improve their health (U.S. Department of Health and Human Services, 2018). Despite well-established benefits, only 1 in 4 U.S. adults meet the combined aerobic and muscle-strengthening physical activity guidelines (Centers for Disease Control and Prevention). The built environment, defined as the physical makeup of where people live, learn, work, and play, can support or inhibit physical activity. The Community Preventive Services Task Force (CPSTF) recommends built environment strategies that combine new or improved pedestrian, bicycle, or transit transportation systems (i.e., activity-friendly routes) with land use components (i.e., connecting everyday destinations) (Community Preventive Services Task Force, 2016). Active People, Healthy NationSM is a national initiative led by the Centers for Disease Control and Prevention (CDC) to help 27 million Americans become more physically active by 2027 (Fulton et al., 2018). To reach this goal, states and communities can implement strategies for increasing physical activity (Schmid et al., 2021) across sectors and settings. Each strategy can be designed to ensure equitable access to opportunities for physical activity. However, implementation of physical activity–supportive policies across the United States remains low. The National Complete Streets Coalition reports that only 1,600 jurisdictions (mainly cities) have adopted Complete Streets policies (Smart Growth America); this is a fraction of all U.S. jurisdictions, and the quality of policies varies. There remains a need for applied research to translate knowledge into practice for implementing evidence-based policies to increase physical activity. Best practices that inform the implementation of these strategies are also needed to support communities and states. |
School connectedness and risk behaviors and experiences among high school students - Youth Risk Behavior Survey, United States, 2021
Wilkins NJ , Krause KH , Verlenden JV , Szucs LE , Ussery EN , Allen CT , Stinson J , Michael SL , Ethier KA . MMWR Suppl 2023 72 (1) 13-21 School connectedness, defined as students' belief that adults and peers in their school care about their learning as well as about them as persons, has been linked to positive educational, behavioral, and health outcomes in adolescence and into adulthood. Data from the 2021 nationally representative Youth Risk Behavior Survey, conducted during the COVID-19 pandemic, were used to estimate prevalence of students' perception of school connectedness and examine associations between school connectedness and seven risk behaviors and experiences: poor mental health, marijuana use, prescription opioid misuse, sexual intercourse, unprotected sex, experiencing forced sex, and missing school because of feeling unsafe. Prevalence estimates were generated and pairwise t-tests were used to detect differences among student subpopulations by sex, grade, race and ethnicity, and sexual identity; Wald chi-square tests were used to detect differences in risk behaviors by level of connectedness within a subpopulation. Logistic regression models were used to estimate prevalence ratios comparing the prevalence of risk behaviors and experiences of students with high connectedness with students with low connectedness, stratified by demographics. During 2021, 61.5% of U.S. high school students reported feeling connected to others at school. In addition, school connectedness was associated with lower prevalence of every risk behavior and experience examined in this study, although certain associations differed by race and ethnicity and sexual identity (e.g., school connectedness was associated with better mental health outcomes for youths with heterosexual, bisexual, and questioning or other sexual identities, but not for youths who identified as lesbian or gay). These findings can guide public health interventions that promote youth well-being by creating school environments where all youths have a sense of belonging and feel they are cared for and supported. |
Awareness and knowledge of the physical activity guidelines for Americans, 2nd Edition
Chen TJ , Whitfield GP , Watson KB , Fulton JE , Ussery EN , Hyde ET , Rose K . J Phys Act Health 2023 20 (8) 1-10 BACKGROUND: Assessing awareness and knowledge of the Physical Activity Guidelines for Americans, 2nd edition (Guidelines), released in 2018, is important for monitoring factors that contribute to increasing physical activity. METHODS: We estimated prevalence of awareness and knowledge of the adult aerobic guideline (≥150 min/wk of moderate-intensity equivalent aerobic physical activity preferably spread out over a week) among adults (n = 3471) and of the youth aerobic guideline (≥60 min/d of mostly moderate- to vigorous-intensity aerobic physical activity) among a subset of parents (n = 744) from a nationwide sample of US adults in the 2019 FallStyles survey. We estimated odds ratios using logistic regression, adjusting for demographic and other characteristics. RESULTS: Approximately 1 in 10 US adults and parents reported being aware of the Guidelines. Only 3% of adults knew the correct adult aerobic guideline. The most common responses were "don't know/not sure" (44%) and "30 minutes a day, 5 or more days a week" (28%). Among parents, 15% knew the youth aerobic guideline. Awareness and knowledge tended to be lower with lower education and income. CONCLUSIONS: Limited awareness and knowledge of the Guidelines suggest communication about the Guidelines could be strengthened, especially among adults with low income or education. |
Systematic review of active travel to school surveillance in the United States and Canada
Wolfe MK , McDonald NC , Ussery EN , George SM , Watson KB . J Healthy Eat Act Living 2023 1 (3) 127-141 Active travel to school is one way youths can incorporate physical activity into their daily schedule. It is unclear the extent to which active travel to school is systematically monitored at local, state, or national levels. To determine the scope of active travel to school surveillance in the US and Canada and catalog the types of measures captured, we conducted a systematic review of peer-reviewed literature documenting active travel to school surveillance published from 2004 to February 2018. A study was included if it addressed children's school travel mode across two or more time periods in the US or Canada. Criteria were applied to determine whether a data source was considered an active travel to school surveillance system. We identified 15 unique data sources; 4 of these met our surveillance system criteria. One system is conducted in the US, is nationally representative, and occurs every 5-8 years. Three are conducted in Canada, are limited geographically to regions and provinces, and are administered with greater frequency (e.g., 2-year cycles). School travel mode was the primary measure assessed, most commonly through parent report. None of the systems collected data on school policies or program supports related to active travel to school. We concluded that incorporating questions related to active travel to school behaviors into existing surveillance systems, as well as maintaining them over time, would enable more consistent monitoring. Concurrently capturing behavioral information along with related environmental, policy, and program supports may inform efforts to promote active travel to school. |
Differences in park plans and policies across U.S. municipalities
Peterson EL , Carlson SA , Ussery EN , Dunn I , Brown DR , Galuska DA . J Park Recreat Admi 2021 39 (4) Park planning documents may be valuable tools in order to promote policies and direct resources toward parks. However, the prevalence of such planning documents and policies specific to parks across municipal characteristics is not well known. This study compares the presence of parks and recreation plans and policies that address park safety and maintenance by municipality characteristics. Na-tionally representative data from the 2014 National Survey of Community-Based Policy and Environmental Supports for Healthy Eating and Active Living were analyzed (n=2005, response rate: 45%). About 7 out of 10 U.S. municipalities with a population of at least 1,000 reported having a parks and recreation plan. Prevalence of specific park or outdoor recreation policies was 78% for lighting, 85% for patrols by police and security, and 87% for maintenance of green space and equipment. The prevalence of a parks and recreation plan and of specific park or outdoor recreation policies were significantly lower in the smaller communities examined in this study. Most communities with at least 1,000 residents have park planning documents and policies, and opportunities may exist for practitioners to leverage the planning process to better engage residents. Future studies could in-vestigate the role and importance of using planning documents, policies, or bud-get provisions to address park access and quality in less populous municipalities. © 2020 Sagamore-Venture Publishing. |
Surveillance of physical activity and sedentary behavior among youth and adults in the United States: History and opportunities
Omura JD , Whitfield GP , Chen TJ , Hyde ET , Ussery EN , Watson KB , Carlson SA . J Phys Act Health 2021 18 S6-s24 BACKGROUND: Surveillance is a core function of public health, and approaches to national surveillance of physical activity and sedentary behavior have evolved over the past 2 decades. The purpose of this paper is to provide an overview of surveillance of physical activity and sedentary behavior in the United States over the past 2 decades, along with related challenges and emerging opportunities. METHODS: The authors reviewed key national surveillance systems for the assessment of physical activity and sedentary behavior among youth and adults in the United States between 2000 and 2019. RESULTS: Over the past 20 years, 8 surveillance systems have assessed physical activity, and 5 of those have assessed sedentary behavior. Three of the 8 originated in nonpublic health agencies. Most systems have assessed physical activity and sedentary behavior via surveys. However, survey questions varied over time within and also across systems, resulting in a wide array of available data. CONCLUSION: The evolving nature of physical activity surveillance in the United States has resulted in both broad challenges (eg, balancing content with survey space; providing data at the national, state, and local level; adapting traditional physical activity measures and survey designs; and addressing variation across surveillance systems) and related opportunities. |
Change in prevalence of meeting the aerobic physical activity guideline among US adults, by states and territories-Behavioral Risk Factor Surveillance System, 2011 and 2019
Ussery EN , Omura JD , McCain K , Watson KB . J Phys Act Health 2021 18 S84-s85 Overall, the percentage of US adults who met the aerobic physical activity guideline1,I was 51.3% in 2011 and 51.3% in 2019 (P = .876).II In 2011, the prevalence of meeting the aerobic guideline was <45% in 7 jurisdictions, 45% to <50% in 16 jurisdictions, 50% to <55% in 16 jurisdictions, and ≥55% in 14 jurisdictions. In 2019, the prevalence of meeting the aerobic guideline was <45% in 4 jurisdictions, 45% to <50% in 17 jurisdictions, 50% to <55% in 16 jurisdictions, and ≥55% in 15 jurisdictions. Between 2011 and 2019, the prevalence significantly decreased in 12 jurisdictions (CA, CO, HI, KY, ME, MA, MO, OH, OK, OR, VA, PR), significantly increased in 11 jurisdictions (AL, KS, LA, MD, MN, MT, NC, TN, VT, WA, WV), and did not significantly change in 29 jurisdictions.III The absolute change in prevalence ranged from an 11.0 percentage point decrease in Kentucky to an 8.6 percentage point increase in Tennessee. |
Trends in self-reported sitting time by physical activity levels among US adults, NHANES 2007/2008-2017/2018
Ussery EN , Whitfield GP , Fulton JE , Galuska DA , Matthews CE , Katzmarzyk PT , Carlson SA . J Phys Act Health 2021 18 S74-s83 BACKGROUND: High levels of sedentary behavior and physical inactivity increase the risk of premature mortality and several chronic diseases. Monitoring national trends and correlates of sedentary behavior and physical inactivity can help identify patterns of risk in the population over time. METHODS: The authors used self-reported data from the National Health and Nutrition Examination Surveys (2007/2008-2017/2018) to estimate trends in US adults' mean daily sitting time, overall, and stratified by levels of leisure-time and multidomain physical activity, and in the joint prevalence of high sitting time (>8 h/d) and physical inactivity. Trends were tested using orthogonal polynomial contrasts. RESULTS: Overall, mean daily sitting time increased by 19 minutes from 2007/2008 (332 min/d) to 2017/2018 (351 min/d) (Plinear < .05; Pquadratic < .05). The highest point estimate occurred in 2013/2014 (426 min/d), with a decreasing trend observed after this point (Plinear < .05). Similar trends were observed across physical activity levels and domains, with one exception: an overall linear increase was not observed among sufficiently active adults. The mean daily sitting time was lowest among highly active adults compared with less active adults when using the multidomain physical activity measure. CONCLUSIONS: Sitting time among adults increased over the study period but decreased in recent years. |
Trends in aerobic physical activity participation across multiple domains among US adults, National Health and Nutrition Examination Survey 2007/2008 to 2017/2018
Whitfield GP , Ussery EN , Saint-Maurice PF , Carlson SA . J Phys Act Health 2021 18 S64-s73 BACKGROUND: Understanding how participation is changing across domains of physical activity is important for monitoring progress and informing promotion efforts. The authors examined changes in physical activity participation in the National Health and Nutrition Examination Survey 2007/2008 to 2017/2018. METHODS: The prevalence of inactivity, insufficient activity, and meeting the aerobic physical activity guideline in multidomain physical activity and each domain (leisure time, occupational/household, and transportation) was estimated for each cycle and stratified by selected characteristics. The authors tested trends over time and overall changes (2017/2018 vs 2007/2008). RESULTS: For multidomain physical activity, the prevalence of inactivity decreased linearly; meeting the aerobic guideline increased nonmonotonically, and the 2017/2018 prevalence (68.1%) was higher than 2007/2008 (64.1%). Similar findings were observed for adults aged ≥65 years, non-Hispanic Blacks, Hispanics, high school graduates, and adults with obesity. Domain-specific results varied, but decreasing trends in inactivity and increasing trends in meeting the guideline were consistently observed across subgroups for occupational/household activity. Meeting the guideline through transportation activity was rare. CONCLUSIONS: Increases in meeting the guideline and decreases in inactivity in multidomain activity and selected domains are encouraging results, especially among subgroups historically reporting low activity participation. Activity promotion efforts are important to maintain progress, and the transportation domain may be an underutilized source of physical activity. |
County-Level COVID-19 Vaccination Coverage and Social Vulnerability - United States, December 14, 2020-March 1, 2021.
Hughes MM , Wang A , Grossman MK , Pun E , Whiteman A , Deng L , Hallisey E , Sharpe JD , Ussery EN , Stokley S , Musial T , Weller DL , Murthy BP , Reynolds L , Gibbs-Scharf L , Harris L , Ritchey MD , Toblin RL . MMWR Morb Mortal Wkly Rep 2021 70 (12) 431-436 The U.S. COVID-19 vaccination program began in December 2020, and ensuring equitable COVID-19 vaccine access remains a national priority.* COVID-19 has disproportionately affected racial/ethnic minority groups and those who are economically and socially disadvantaged (1,2). Thus, achieving not just vaccine equality (i.e., similar allocation of vaccine supply proportional to its population across jurisdictions) but equity (i.e., preferential access and administra-tion to those who have been most affected by COVID-19 disease) is an important goal. The CDC social vulnerability index (SVI) uses 15 indicators grouped into four themes that comprise an overall SVI measure, resulting in 20 metrics, each of which has national and state-specific county rankings. The 20 metric-specific rankings were each divided into lowest to highest tertiles to categorize counties as low, moderate, or high social vulnerability counties. These tertiles were combined with vaccine administration data for 49,264,338 U.S. residents in 49 states and the District of Columbia (DC) who received at least one COVID-19 vaccine dose during December 14, 2020-March 1, 2021. Nationally, for the overall SVI measure, vaccination coverage was higher (15.8%) in low social vulnerability counties than in high social vulnerability counties (13.9%), with the largest coverage disparity in the socioeconomic status theme (2.5 percentage points higher coverage in low than in high vulnerability counties). Wide state variations in equity across SVI metrics were found. Whereas in the majority of states, vaccination coverage was higher in low vulnerability counties, some states had equitable coverage at the county level. CDC, state, and local jurisdictions should continue to monitor vaccination coverage by SVI metrics to focus public health interventions to achieve equitable coverage with COVID-19 vaccine. |
Demographic Characteristics of Persons Vaccinated During the First Month of the COVID-19 Vaccination Program - United States, December 14, 2020-January 14, 2021.
Painter EM , Ussery EN , Patel A , Hughes MM , Zell ER , Moulia DL , Scharf LG , Lynch M , Ritchey MD , Toblin RL , Murthy BP , Harris LQ , Wasley A , Rose DA , Cohn A , Messonnier NE . MMWR Morb Mortal Wkly Rep 2021 70 (5) 174-177 In December 2020, two COVID-19 vaccines (Pfizer-BioNTech and Moderna) were authorized for emergency use in the United States for the prevention of coronavirus disease 2019 (COVID-19).* Because of limited initial vaccine supply, the Advisory Committee on Immunization Practices (ACIP) prioritized vaccination of health care personnel(†) and residents and staff members of long-term care facilities (LTCF) during the first phase of the U.S. COVID-19 vaccination program (1). Both vaccines require 2 doses to complete the series. Data on vaccines administered during December 14, 2020-January 14, 2021, and reported to CDC by January 26, 2021, were analyzed to describe demographic characteristics, including sex, age, and race/ethnicity, of persons who received ≥1 dose of COVID-19 vaccine (i.e., initiated vaccination). During this period, 12,928,749 persons in the United States in 64 jurisdictions and five federal entities(§) initiated COVID-19 vaccination. Data on sex were reported for 97.0%, age for 99.9%, and race/ethnicity for 51.9% of vaccine recipients. Among persons who received the first vaccine dose and had reported demographic data, 63.0% were women, 55.0% were aged ≥50 years, and 60.4% were non-Hispanic White (White). More complete reporting of race and ethnicity data at the provider and jurisdictional levels is critical to ensure rapid detection of and response to potential disparities in COVID-19 vaccination. As the U.S. COVID-19 vaccination program expands, public health officials should ensure that vaccine is administered efficiently and equitably within each successive vaccination priority category, especially among those at highest risk for infection and severe adverse health outcomes, many of whom are non-Hispanic Black (Black), non-Hispanic American Indian/Alaska Native (AI/AN), and Hispanic persons (2,3). |
Perceived importance of physical activity and walkable neighborhoods among US adults, 2017
Carlson SA , Ussery EN , Watson KB , Cornett KA , Fulton JE . Prev Chronic Dis 2020 17 E168 The importance of physical activity and community-level promotion strategies are well established, but little is known about adult perception of the importance of physical activity. In a nationwide sample of US adults, we examined self-reported importance of regular physical activity and the importance of living in walkable neighborhoods. About 55% of adults strongly agreed that regular physical activity is important, 40% strongly agreed that living in a walkable neighborhood is important, and 31% strongly agreed that both are important. Separately for each measure, estimates were lower among adults with lower education levels and who did not meet the aerobic physical activity guideline. Opportunities exist to improve the perception of the importance of physical activity and the importance of walkable neighborhoods. |
Combining data from assessments of leisure, occupational, household, and transportation physical activity among US adults, NHANES 2011-2016
Whitfield GP , Ussery EN , Carlson SA . Prev Chronic Dis 2020 17 E117 Physical activity occurs in 4 domains (leisure, occupational, household, and transportation), but US surveillance often focuses on leisure-time only. We compared estimates of self-reported leisure-time physical activity and estimates of all-domain activity among adults in the National Health and Nutrition Examination Survey for 2011-2016. During the study period, 38.6% met the aerobic physical activity guideline in leisure-time, 58.5% in leisure-time and occupational/household activity, and 63.7% in all domains. Differences within most subgroups when using all domains were similar to differences when using leisure-time activity only, except that we observed no urban/rural differences in the multidomain assessment. Assessment of multiple domains of activity instead of leisure-time-only activity affects prevalence estimates to a greater extent than it affects subgroup differences. |
Update: Characteristics of Health Care Personnel with COVID-19 - United States, February 12-July 16, 2020.
Hughes MM , Groenewold MR , Lessem SE , Xu K , Ussery EN , Wiegand RE , Qin X , Do T , Thomas D , Tsai S , Davidson A , Latash J , Eckel S , Collins J , Ojo M , McHugh L , Li W , Chen J , Chan J , Wortham JM , Reagan-Steiner S , Lee JT , Reddy SC , Kuhar DT , Burrer SL , Stuckey MJ . MMWR Morb Mortal Wkly Rep 2020 69 (38) 1364-1368 As of September 21, 2020, the coronavirus disease 2019 (COVID-19) pandemic had resulted in 6,786,352 cases and 199,024 deaths in the United States.* Health care personnel (HCP) are essential workers at risk for exposure to patients or infectious materials (1). The impact of COVID-19 on U.S. HCP was first described using national case surveillance data in April 2020 (2). Since then, the number of reported HCP with COVID-19 has increased tenfold. This update describes demographic characteristics, underlying medical conditions, hospitalizations, and intensive care unit (ICU) admissions, stratified by vital status, among 100,570 HCP with COVID-19 reported to CDC during February 12-July 16, 2020. HCP occupation type and job setting are newly reported. HCP status was available for 571,708 (22%) of 2,633,585 cases reported to CDC. Most HCP with COVID-19 were female (79%), aged 16-44 years (57%), not hospitalized (92%), and lacked all 10 underlying medical conditions specified on the case report form(†) (56%). Of HCP with COVID-19, 641 died. Compared with nonfatal COVID-19 HCP cases, a higher percentage of fatal cases occurred in males (38% versus 22%), persons aged ≥65 years (44% versus 4%), non-Hispanic Asians (Asians) (20% versus 9%), non-Hispanic Blacks (Blacks) (32% versus 25%), and persons with any of the 10 underlying medical conditions specified on the case report form (92% versus 41%). From a subset of jurisdictions reporting occupation type or job setting for HCP with COVID-19, nurses were the most frequently identified single occupation type (30%), and nursing and residential care facilities were the most common job setting (67%). Ensuring access to personal protective equipment (PPE) and training, and practices such as universal use of face masks at work, wearing masks in the community, and observing social distancing remain critical strategies to protect HCP and those they serve. |
Physical activity before and during pregnancy, Colorado Pregnancy Risk Assessment Monitoring System, 2012-2015
Ussery EN , Hyde ET , Bombard JM , Juhl AL , Kim SY , Carlson SA . Prev Chronic Dis 2020 17 E55 We used 2012-2015 data from the Colorado Pregnancy Risk Assessment Monitoring System to describe changes in self-reported physical activity (PA) before and during pregnancy and used logistic regression to examine factors associated with regular PA. The prevalence of regular PA (ie, 30 or more minutes per day on 5 or more days per week) was 19.1% before pregnancy and decreased to 10.2% during pregnancy. At both times, adjusted odds of regular PA were lower among women who were overweight or had obesity before pregnancy than among those with normal weight. Findings suggest that most women with a recent live birth in Colorado, particularly those who are overweight or have obesity, are not obtaining many health benefits of PA either before or during pregnancy. |
The influence of removing the ten-minute bout requirement on national physical activity estimates
Ussery EN , Watson KB , Carlson SA . Prev Chronic Dis 2020 17 E19 The updated Physical Activity Guidelines for Americans (2nd edition) removes the requirement that physical activity should occur in bouts lasting 10 minutes or more to count toward the minimum aerobic guideline. Using self-reported data from the 2017 Behavioral Risk Factor Surveillance System (N = 386,960), we examined differences in national physical activity estimates with and without this requirement. Overall, 1.9% of adults reported activities in short bouts (<10 minutes). When excluding short bouts, 29.9% were inactive, 20.7% were insufficiently active, and 49.4% were active. When including short bouts, 29.1% were inactive, 21.4% were insufficiently active, and 49.5% were active. Eliminating the 10-minute-bout requirement had little effect on physical activity estimates. |
Characteristics of hospitalized and nonhospitalized patients in a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury - United States, November 2019
Chatham-Stephens K , Roguski K , Jang Y , Cho P , Jatlaoui TC , Kabbani S , Glidden E , Ussery EN , Trivers KF , Evans ME , King BA , Rose DA , Jones CM , Baldwin G , Delaney LJ , Briss P , Ritchey MD . MMWR Morb Mortal Wkly Rep 2019 68 (46) 1076-1080 CDC, the Food and Drug Administration (FDA), state and local health departments, and public health and clinical stakeholders are investigating a nationwide outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) (1). As of November 13, 2019, 49 states, the District of Columbia, and two U.S. territories (Puerto Rico and U.S. Virgin Islands) have reported 2,172 EVALI cases to CDC, including 42 (1.9%) EVALI-associated deaths. To inform EVALI surveillance, including during the 2019-20 influenza season, case report information supplied by states for hospitalized and nonhospitalized patients with EVALI were analyzed using data collected as of November 5, 2019. Among 2,016 EVALI patients with available data on hospitalization status, 1,906 (95%) were hospitalized, and 110 (5%) were not hospitalized. Demographic characteristics of hospitalized and nonhospitalized patients were similar; most were male (68% of hospitalized versus 65% of nonhospitalized patients), and most were aged <35 years (78% of hospitalized versus 74% of nonhospitalized patients). These patients also reported similar use of tetrahydrocannabinol (THC)-containing products (83% of hospitalized versus 84% of nonhospitalized patients). Given the similarity between hospitalized and nonhospitalized EVALI patients, the potential for large numbers of respiratory infections during the emerging 2019-20 influenza season, and the potential difficulty in distinguishing EVALI from respiratory infections, CDC will no longer collect national data on nonhospitalized EVALI patients. Further collection of data on nonhospitalized patients will be at the discretion of individual state, local, and territorial health departments. Candidates for outpatient management of EVALI should have normal oxygen saturation (>/=95% while breathing room air), no respiratory distress, no comorbidities that might compromise pulmonary reserve, reliable access to care, strong social support systems, and should be able to ensure follow-up within 24-48 hours of initial evaluation and to seek medical care promptly if respiratory symptoms worsen. Health care providers should emphasize the importance of annual influenza vaccination for all persons aged >/=6 months, including persons who use e-cigarette, or vaping, products (2,3). |
Update: Characteristics of patients in a national outbreak of e-cigarette, or vaping, product use-associated lung injuries - United States, October 2019

MMWR Morb Mortal Wkly Rep 2019 68 (43) 985-989 CDC, the Food and Drug Administration, state and local health departments, and other public health and clinical stakeholders are investigating a national outbreak of electronic-cigarette (e-cigarette), or vaping, product use-associated lung injury (EVALI) (1). As of October 22, 2019, 49 states, the District of Columbia (DC), and the U.S. Virgin Islands have reported 1,604 cases of EVALI to CDC, including 34 (2.1%) EVALI-associated deaths in 24 states. Based on data collected as of October 15, 2019, this report updates data on patient characteristics and substances used in e-cigarette, or vaping, products (2) and describes characteristics of EVALI-associated deaths. The median age of EVALI patients who survived was 23 years, and the median age of EVALI patients who died was 45 years. Among 867 (54%) EVALI patients with available data on use of specific e-cigarette, or vaping, products in the 3 months preceding symptom onset, 86% reported any use of tetrahydrocannabinol (THC)-containing products, 64% reported any use of nicotine-containing products, and 52% reported use of both. Exclusive use of THC-containing products was reported by 34% of patients and exclusive use of nicotine-containing products by 11%, and for 2% of patients, no use of either THC- or nicotine-containing products was reported. Among 19 EVALI patients who died and for whom substance use data were available, 84% reported any use of THC-containing products, including 63% who reported exclusive use of THC-containing products; 37% reported any use of nicotine-containing products, including 16% who reported exclusive use of nicotine-containing products. To date, no single compound or ingredient used in e-cigarette, or vaping, products has emerged as the cause of EVALI, and there might be more than one cause. Because most patients reported using THC-containing products before symptom onset, CDC recommends that persons should not use e-cigarette, or vaping, products that contain THC. In addition, because the specific compound or ingredient causing lung injury is not yet known, and while the investigation continues, persons should consider refraining from the use of all e-cigarette, or vaping, products. |
Walking as an opportunity for cardiovascular disease prevention
Omura JD , Ussery EN , Loustalot F , Fulton JE , Carlson SA . Prev Chronic Dis 2019 16 E66 INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of death in the United States, and increasing physical activity can help prevent and manage disease. Walking is an easy way for most adults to be more active and may help people at risk for CVD avoid inactivity, increase their physical activity levels, and improve their cardiovascular health. To guide efforts that promote walking for CVD prevention and management, we estimated the prevalence of walking among US adults by CVD risk status. METHODS: Nationally representative data on walking from participants (N = 29,742) in the 2015 National Health Interview Survey Cancer Control Supplement were analyzed. We estimated prevalence of walking (ie, any, transportation, and leisure) overall and by CVD status. We defined CVD status as either not having CVD and not at risk for CVD; being at risk for CVD (overweight or having obesity plus 1 or more additional risk factors); or having CVD. We defined additional risk factors as diabetes, high cholesterol, or hypertension. Odds ratios were estimated by using logistic regression models adjusted for respondent characteristics. RESULTS: Prevalence of any walking decreased with increasing CVD risk (no CVD/not at risk, 66.6%; at risk: overweight or has obesity with 1 risk factor, 63.0%; with 2 risk factors, 59.5%; with 3 risk factors, 53.6%; has CVD, 50.2%). After adjusting for respondent characteristics, the odds of any walking and leisure walking decreased with increasing CVD risk. However, CVD risk was not associated with walking for transportation. CONCLUSIONS: Promoting walking may be a way to help adults avoid inactivity and encourage an active lifestyle for CVD prevention and management. |
Trends in Meeting physical activity guidelines among urban and rural dwelling adults - United States, 2008-2017
Whitfield GP , Carlson SA , Ussery EN , Fulton JE , Galuska DA , Petersen R . MMWR Morb Mortal Wkly Rep 2019 68 (23) 513-518 Since the release of the 2008 Physical Activity Guidelines for Americans (https://health.gov/paguidelines/2008/pdf/paguide.pdf), the age-adjusted percentage of adults meeting the combined aerobic and muscle-strengthening guidelines increased from 18.2% to 24.3% in 2017 (1). Trends in urban and rural areas, across demographic subgroups, and among subgroups within urban and rural areas have not been reported. CDC analyzed 2008-2017 National Health Interview Survey (NHIS) data to examine trends in the age-standardized prevalence of meeting physical activity guidelines among adults aged >/=18 years living in urban and rural areas. Among urban and rural residents, prevalence increased from 19.4% to 25.3% and from 13.3% to 19.6%, respectively. Nationally, all demographic subgroups and regions experienced increases over this period; increases for several groups were not consistent year-to-year. Among urban residents, the prevalence was higher during 2016-2017 than during 2008-2009 for all demographic subgroups and regions. During the same period, prevalence was higher across all rural-dwelling subgroups except Hispanics, adults with a college education, and those living in the South U.S. Census region. Urban and rural communities can implement evidence-based approaches, including improved community design, improved access to indoor and outdoor recreation facilities, social support programs, and community-wide campaigns to make physical activity the safe and easy choice for persons of all ages and abilities (2-4). Incorporating culturally appropriate strategies into local programs might help address differences across subgroups. |
National-level environmental perceptions and walking among urban and rural residents: Informing surveillance of walkability
Whitfield GP , Carlson SA , Ussery EN , Watson KB , Berrigan D , Fulton JE . Prev Med 2019 123 101-108 Built environments that provide activity-friendly routes (e.g., sidewalks) to everyday destinations (e.g., shops) can increase physical activity. Surveillance of supports and destinations is important, and identifying which are associated with walking could prioritize surveillance questions. Our purpose was to identify the significant associations between supports and destinations with walking among a nationally-representative sample of urban- and rural-dwelling adults. Participants in the 2015 National Health Interview Survey, Cancer Control Supplement (n=29,925) reported the near-home presence of walkable supports (roads, sidewalks, paths, or trails; sidewalks on most streets), destinations (shops; transit; movies, libraries, or churches; relaxing places), and past-week walking for leisure or transportation. We used stepwise logistic regression to quantify associations between supports and destinations and walking, including by urban/rural residence. We calculated the prevalence of walking across counts of reported elements by urban/rural residence. Among all participants, roads, sidewalks, paths, or trails and relaxing destinations were associated with leisure walking. Among urban residents, sidewalks on most streets and all four destination types were associated with transportation walking; among rural residents, roads, sidewalks, paths, or trails; movies, libraries, or churches; and relaxing destinations were associated with transportation walking. Walking was more common when more environmental elements were reported. To improve efficiency, communities may match surveillance priorities to behavioral priorities (i.e., leisure versus transportation walking) and environmental context (i.e., urban/rural areas). Surveillance of environments supporting leisure walking might focus on recreation-oriented spaces. Surveillance of environments supporting transportation walking might differ for urban and rural areas, and assessing destinations may be particularly important. |
Sampling methodology and reliability of a representative walkability audit
Ussery EN , Omura JD , Paul P , Orr J , Spoon C , Geremia C , Carlson SA . J Transp Health 2019 12 75-85 Background: Physical inactivity is a public health concern in the US Virgin Islands (USVI). A contributing factor may be a lack of pedestrian infrastructure and other environmental supports for walking. In this manuscript, we describe the methods used to conduct a walkability audit of environmental features related to physical activity in the USVI. Methods: In 2016, volunteer auditors conducted the audit using a modified version of the Microscale Audit of Pedestrian Streetscapes tool. A two-stage sampling method was developed using publicly available census data to select a sample of estates (n=46) and street segments (n=1550; 99.2 km) across the USVI. A subset of segments was audited by two independent auditors, and inter-rater reliability was assessed using Cohen's kappa and percent agreement. Results: Audits were completed on 1114 segments (94.6 km), and estimates were weighted to represent accessible public street length in the study area (1155.9 km). Most items on the audit tool (62.7%) demonstrated good to excellent reliability. We found that it was feasible to conduct a reliable audit of environmental features related to physical activity across a large sample of streets in the USVI. Conclusions: These methods can be replicated in other settings to collect comprehensive data that can be used to guide strategies to improve the walkability of communities. |
Joint prevalence of sitting time and leisure-time physical activity among US adults, 2015-2016
Ussery EN , Fulton JE , Galuska DA , Katzmarzyk PT , Carlson SA . JAMA 2018 320 (19) 2036-2038 This study uses 2015-2016 National Health and Nutrition Examination Survey data to assess prevalence of daily sitting time and weekly leisure-time physical activity among US adults. |
Geographic and urban-rural differences in walking for leisure and transportation
Carlson SA , Whitfield GP , Peterson EL , Ussery EN , Watson KB , Berrigan D , Fulton JE . Am J Prev Med 2018 55 (6) 887-895 INTRODUCTION: Walking can serve many purposes, such as transportation (to get some place) or leisure (for fun, relaxation, or exercise); therefore, it provides many opportunities for people to be physically active. This study examines geographic and urban-rural differences in walking in the U.S. METHODS: Adult respondents (aged >/=18 years) to the 2015 National Health Interview Survey reported participation in and time spent (minutes per week) walking for transportation and leisure in the past week. In 2017, prevalence and time spent walking (among walkers) for any, leisure, and transportation walking were estimated by nine expanded regions and urban-rural designation. RESULTS: Prevalence of any walking ranged from 50.8% (East South Central) to 72.4% (Pacific); for leisure walking 43.9% (East South Central) to 60.6% (Pacific); and transportation walking 17.8% (East South Central) to 43.5% (New England). Among walkers, mean minutes spent walking per week ranged from 77.4 (East South Central) to 101.6 (Pacific); for leisure walking 70.5 (West South Central) to 85.9 (Mountain); and for transportation walking 47.4 (East South Central) to 66.4 (Middle Atlantic). Overall, there were urban-rural differences in prevalence of walking; however, differences depended on walking purpose and expanded region. Time spent walking was similar in urban and rural areas. CONCLUSIONS: Regional differences in walking prevalence and time spent walking exist. Urban-rural differences in prevalence of walking differ based on region and purpose; however, rural areas had a lower prevalence of walking than urban areas regardless of purpose in southern regions. Opportunities exist to improve walking, particularly among southern regions with a focus on rural areas. |
Transportation and leisure walking among U.S. adults: Trends in reported prevalence and volume, National Health Interview Survey 2005-2015
Ussery EN , Carlson SA , Whitfield GP , Watson KB , Berrigan D , Fulton JE . Am J Prev Med 2018 55 (4) 533-540 INTRODUCTION: Promotion of walking is a promising strategy for increasing physical activity levels in the U.S. The proportion of adults who report walking for either transportation or leisure has increased in recent years, but evidence on trends in walking for specific purposes is limited. METHODS: The 2005, 2010, and 2015 National Health Interview Survey assessed self-reported participation in and volume (minutes/week) of walking for transportation and leisure in the past week among adults aged >/=18 years. Linear and quadratic trends in the prevalence and mean volume of walking for each purpose were evaluated using logistic and linear regression. Analyses were performed in 2017. RESULTS: The prevalence of transportation walking increased from 28.4% (2005) to 31.7% (2015) (linear trend: p<0.05). Leisure walking prevalence increased from 42.1% (2005) to 52.1% (2015), but the increased stalled from 2010 to 2015 with only a 2.3 percentage point increase (linear and quadratic trends: p<0.05). Across purposes, the mean walking volume decreased from 2005 to 2015, with no significant changes between 2010 and 2015 (linear and quadratic trends: p<0.05). The proportion of adults who walked for both transportation and leisure in the past week increased steadily (linear trend: p<0.05), and this group reported the greatest total volume of walking. CONCLUSIONS: Although the prevalence of self-reported transportation and leisure walking increased during the last decade, the time spent walking has decreased. Strategies that encourage walking for multiple purposes may present an opportunity for increasing both participation in walking and the amount of time spent walking. |
Community and street-scale supports for walking in the US Virgin Islands before the 2017 hurricanes
Omura JD , Ussery EN , Carlson SA , Arnold-Lewis K , Orr J , McGuire DO , Lewis L , Paul P , Peterson EL , Fulton JE , Ellis EM . Am J Public Health 2018 108 (8) e1-e4 OBJECTIVES: To determine the prevalence of community and street-scale design features that promote walking across the US Virgin Islands (USVI). METHODS: In May 2016, the USVI Department of Health, with technical assistance from the Centers for Disease Control and Prevention, conducted a territory-wide audit with a validated tool. We selected street segments (n = 1114) via a 2-stage sampling method, and estimates were weighted to be representative of publicly accessible street length. RESULTS: Overall, 10.7% of the street length contained a transit stop, 11.3% had sidewalks, 21.7% had at least 1 destination (e.g., stores, restaurants), 27.4% had a traffic calming feature (e.g., speed humps), and 53.2% had at least some street lighting. Several features were less prevalent on residential streets compared with commercial streets, including transit stops, sidewalks, destinations, and street lighting (P < .01). CONCLUSIONS: Across the USVI, community and street-scale features supportive of walking were uncommon. Improving community and street-scale design in the USVI, particularly in residential areas, could increase physical activity by enhancing walkability and therefore improve public health. These data can be used to inform community planning in the USVI. (Am J Public Health. Published online ahead of print June 21, 2018: e1-e4. doi:10.2105/AJPH.2018.304449). |
Racial and ethnic differences in perceived safety barriers to walking, United States National Health Interview Survey - 2015
Whitfield GP , Carlson SA , Ussery EN , Watson KB , Brown DR , Berrigan D , Fulton JE . Prev Med 2018 114 57-63 Barriers to safe walking may prevent people from being physically active, and previous reports have identified differences in barriers to safe walking across racial and ethnic groups. The purpose of this research was to determine the role demographic characteristics play on racial/ethnic differences in perceived barriers to safe walking and determine if racial/ethnic differences vary by urban/rural residence and Census region. Participants in the 2015 National Health Interview Survey Cancer Control Supplement (n=31,433 adults >/=18years) reported perceived barriers to safe walking (traffic, crime, and animals) and demographic characteristics. Urban/rural residence and Census region were based on home addresses. We calculated adjusted prevalence of barriers by race/ethnicity using logistic regression; geographic differences in barriers across racial/ethnic groups were examined via interaction terms. After adjustment for demographic characteristics, non-Hispanic blacks (blacks) and Hispanics reported crime and animals as barriers more frequently than non-Hispanic whites (whites) (crime: blacks, 22.2%; Hispanics, 16.7%; whites, 9.0%; animals: blacks, 18.0%; Hispanics, 12.4%; whites, 8.5%). Racial/ethnic differences in perceived crime as a barrier were more pronounced in the Northeast and Midwest than in the South and West. Urban-dwelling blacks (all regions) and Hispanics (Midwest and South) reported animals as barriers more frequently than whites. Racial/ethnic differences in perceived barriers to safe walking remained after adjusting for demographic characteristics and varied by geographic location. Addressing perceived crime and animals as barriers to walking could help reduce racial/ethnic differences in physical activity, and several barriers may need to be assessed to account for geographic variation. |
Environmental supports for physical activity, National Health Interview Survey-2015
Whitfield GP , Carlson SA , Ussery EN , Watson KB , Adams MA , James P , Brownson RC , Berrigan D , Fulton JE . Am J Prev Med 2017 54 (2) 294-298 INTRODUCTION: The Guide to Community Preventive Services recommends combined built environment approaches to increase physical activity, including new or enhanced transportation infrastructure (e.g., sidewalks) and land use and environmental design interventions (e.g., close proximity of local destinations). The aim of this brief report is to provide nationally representative estimates of two types of built environment supports for physical activity: near-home walkable infrastructure and destinations, from the 2015 National Health Interview Survey. METHODS: Adults (n=30,453) reported the near-home presence of walkable transportation infrastructure (roads, sidewalks, paths, or trails where you can walk; and whether most streets have sidewalks) and four walkable destination types (shops, stores, or markets; bus or transit stops; movies, libraries, or churches; and places that help you relax, clear your mind, and reduce stress). The prevalence of each, and the count of destination types, was calculated (in 2017) and stratified by demographic characteristics. RESULTS: Overall, 85.1% reported roads, sidewalks, paths, or trails on which to walk, and 62.6% reported sidewalks on most streets. Among destinations, 71.8% reported walkable places to relax; followed by shops (58.0%); transit stops (53.2%); and movies, libraries, or churches (47.5%). For most design elements, prevalence was similar among adults aged 18-24 and 25-34 years, but decreased with age >35 years. Adults in the South reported a lower prevalence of all elements compared with those in other Census regions. CONCLUSIONS: Many U.S. adults report walkable built environment elements near their home; future efforts might target areas with many older adult residents or those living in the South. |
Walking for transportation or leisure among U.S. women and men - National Health Interview Survey, 2005-2015
Ussery EN , Carlson SA , Whitfield GP , Watson KB , Berrigan D , Fulton JE . MMWR Morb Mortal Wkly Rep 2017 66 (25) 657-662 Physical activity confers considerable health benefits, but only half of U.S. adults report participating in levels of aerobic physical activity consistent with guidelines (1,2). Step It Up! The Surgeon General's Call to Action to Promote Walking and Walkable Communities identified walking as an important public health strategy to increase physical activity levels (3). A previous report showed that the self-reported prevalence of walking for transportation or leisure increased by 6 percentage points from 2005 to 2010 (4), but it is unknown whether this increase has been sustained. CDC analyzed National Health Interview Survey (NHIS) data from 2005 (26,551 respondents), 2010 (23,313), and 2015 (28,877) to evaluate trends in the age-adjusted prevalence of self-reported walking among adults aged ≥18 years. The prevalence of walking increased steadily among women, from 57.3% in 2005, to 62.5% in 2010, and to 65.1% in 2015 (significant linear trend). Among men, a significant linear increase in reported walking was observed, from 54.3% in 2005, to 61.8% in 2010, and to 62.8% in 2015, although the increase stalled between 2010 and 2015 (significant linear and quadratic trends). Community design policies and practices that encourage pedestrian activity and programs tailored to the needs of specific population subgroups remain important strategies for promoting walking (3). |
The National Environmental Public Health Tracking Network Access to Parks Indicator: A National County-Level Measure of Park Proximity
Ussery EN , Yngve L , Merriam D , Whitfield G , Foster S , Wendel A , Boehmer T . J Park Recreat Admi 2016 34 (3) 52-63 Parks and recreation departments and public health organizations both work to improve the well-being of their communities. Measuring residential proximity to parks could be a specific area of shared interest, given that proximity to parks is needed for walking access, and the use of parks is, in turn, associated with many physical, social, and mental health benefits. The CDC's publicly available National Environmental Public Health Tracking Network (NEPHTN) Access to Parks Indicator (API) focuses on one major component of access, residential proximity to parks. The API uses a commercial parks database and U.S. Census data to estimate the number and percentage of individuals in the U.S. that live within a half-mile of a park boundary, a measure commonly used to represent park proximity. The API is calculated at the state and county levels and is available for all states and counties in the U.S. Using estimates from the API, we examined the distribution of residential proximity to parks by geography and race/ethnicity. Additionally, we evaluated differences in park proximity by rural/urban status of counties. In 2010, 39% of the total U.S. population lived within a half-mile of a park. This percentage varied widely between states, ranging from 9% in West Virginia to 67% in Hawaii and 88% in the District of Columbia (DC). Park proximity was lowest among non-Hispanic whites (34.2%) and highest among individuals belonging to the non-Hispanic other race category (52.0%). Metropolitan counties had the highest percentage of residents living within a half-mile of a park (43.3%); the percentage was lower in non-metropolitan counties adjacent to a metropolitan county (15.0%) and non-metropolitan counties not adjacent to a metropolitan county (18.5%). Park proximity was higher in metropolitan counties with a larger population size and in non-metropolitan counties with a higher degree of urbanization. The NEPHTN Access to Parks Indicator provides an opportunity to understand park proximity in counties and states throughout the U.S., including identifying disparities that may exist between population subgroups and comparing geographic areas. Parks and recreational professionals can use this information to compare their county or state to other geographic areas and, in combination with local data on parks within their jurisdiction, inform decisions to improve the distribution of parks and the well-being of their communities. |
