Whitfield GP, Ussery EN, Saint-Maurice PF, Carlson SA. Trends in Aerobic Physical Activity Participation Across Multiple Domains Among US Adults, National Health and Nutrition Examination Survey 2007/2008 to 2017/2018. J Phys Act Health 2021; 18:S64-S73. [PMID: 34225255 PMCID: PMC10911582 DOI: 10.1123/jpah.2021-0173] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 05/13/2021] [Accepted: 05/28/2021] [Indexed: 12/16/2022]
Abstract
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.

Abstract
Primary care providers (PCPs) are uniquely positioned to promote physical activity for cardiovascular health. We sought to determine the types of physical activity that PCPs most often recommend to patients at risk for cardiovascular disease (CVD) and how these recommendations vary by PCPs’ physical activity counseling practices. We examined the types of physical activity (walking, supervised exercise sessions, or other) PCPs most often suggested for CVD prevention among respondents to the 2018 DocStyles survey (N = 1,088). Most PCPs (80.0%) suggested walking to their patients at risk for CVD; however, PCPs who infrequently discussed physical activity with their patients at risk for CVD suggested walking less often than those who more frequently discussed physical activity. Walking is an easy and low-cost form of physical activity, and opportunities exist for certain PCPs to promote walking as part of their physical activity counseling practices for CVD prevention.

Abstract
Background There is limited information about the association between long-term leisure time physical activity (LTPA) participation and healthcare costs. The purpose of this study was to investigate the association between LTPA over adulthood with later life healthcare costs in the USA. Methods Using Medicare claims data (between 1999 and 2008) linked to the National Institutes of Health-American Association of Retired Persons (NIH-AARP) Diet and Health Study, we examined associations between nine trajectories of physical activity participation throughout adulthood with Medicare costs. Results Compared with adults who were consistently inactive from adolescence into middle age, average annual healthcare costs were significantly lower for maintainers, adults who maintained moderate (–US$1350 (95% CI: –US$2009 to –US$690) or −15.9% (95% CI: −23.6% to −8.1%)) or high physical activity levels (–US$1200 (95% CI: –US$1777 to –US$622) or −14.1% (95% CI: −20.9% to −7.3%)) and increasers, adults who increased physical activity levels in early adulthood (–US$1874 (95% CI: US$2691 to –US$1057) or −22.0% (95% CI: −31.6% to −12.4%)) or in middle age (–US$824 (95% CI: –US$1580 to –US$69 or −9.7% (95% CI −18.6% to −0.8%)). For the four trajectories where physical activity decreased, the only significant difference was for adults who increased physical activity levels during early adulthood with a decline in middle age (–US$861 (95% CI:–US$1678 to –US$45) or −10.1% (95% CI: −19.7% to −0.5%)). Conclusion Our analyses suggest the healthcare cost burden in later life could be reduced through promotion efforts supporting physical activity participation throughout adulthood.

Abstract
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.

Abstract
Subjective cognitive decline (SCD) is the self-reported experience of worsening or more frequent confusion or memory loss within the previous 12 months and can be one of the earliest symptoms of Alzheimer's disease. Regular physical activity can contribute to the primary, secondary, and tertiary prevention of cognitive decline. At the national level, prevalence estimates of SCD by physical activity level in the United States are currently unknown. The purpose of this study is to examine the prevalence of SCD and resulting functional limitations by physical activity level among US adults aged ≥45 years. Data from 33 states and the District of Columbia participating in the 2015 Behavioral Risk Factor Surveillance System (N = 128,925) were analyzed. We estimated the prevalence of SCD (a positive response to a question about worsening or more frequent confusion or memory loss within the previous 12 months) and resulting functional limitations overall and by self-reported physical activity level based on current guidelines (i.e., active, insufficiently active, and inactive). Odds ratios were estimated using logistic regression models adjusting for respondent characteristics. Overall, 11.3% of US adults aged ≥45 years reported SCD. Prevalence of SCD increased as physical activity level decreased (active: 8.8%; insufficiently active: 11.4%; inactive: 15.7%). Among those with SCD, the prevalence of functional limitations also increased as physical activity level decreased (active: 40.5%; insufficiently active: 50.0%; inactive: 57.4%). These differences largely remained after adjusting for respondent characteristics. Findings highlight the potential public health impact nationally of efforts to promote physical activity for cognitive health.

Abstract
INTRODUCTION In 2019, the National Youth Sports Strategy was released and called for regular analysis, interpretation, and dissemination of U.S. youth sports surveillance data. The purpose of this study is to provide the recent national estimates of U.S. youth aged 6-17 years who participate in sports and examine the differences in participation by demographic characteristics, overall and across age groups. METHODS Nationally representative data on parent-reported youth sports participation from the 2017-2018 National Survey of Children's Health (n=36,779) were analyzed in 2019. The prevalence and 95% CIs of youth sports participation were estimated by demographic characteristics, overall and by age group. Investigators assessed the significant (p<0.05) differences and trends in participation using pairwise t-tests and orthogonal polynomial contrasts and effect modification by age group using logistic regression models. RESULTS Overall, 57.7% (95% CI=56.6, 58.9) of U.S. youth participated in sports. Participation was highest among youth who were aged 10-13 years, male, and white, non-Hispanic and increased with increasing parent/caregiver education and household income (all p<0.05). Differences in participation by demographic characteristics were more pronounced among younger youth. For example, prevalence by household income level ranged from 32.7% to 79.9% among children aged 6-9 years and from 41.6% to 67.2% among youth aged 14-17 years. CONCLUSIONS Although nearly 6 in 10 U.S. youth participate in sports, substantial disparities exist, especially among younger children. Identifying and overcoming the barriers may help increase youth sports participation in the U.S.

Abstract
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.

Abstract
Introduction Active commuting to work is one way people can be physically active and can be influenced by state-level initiatives. The American Community Survey (ACS) is a potential data source to evaluate changes in active commuting at the state level, but state-level changes have not been well documented. We examined state-level changes in estimates of walking, biking, and taking transit to work (combined and separately) among employed persons between 2006 and 2017. Methods Data were from the ACS, a nationally representative annual household survey from the US Census Bureau. We estimated state-level prevalence of walking, bicycling, or taking transit to work (separately and in combination) in 2006 and 2017 and tested differences by year. Results The prevalence of active commuting to work varied widely among states (2017 range: 1.7% in Alabama and Mississippi to 35.0% in New York). Changes from 2006 to 2017 also varied, with 8 states exhibiting a significant increase (Massachusetts [2.7 percentage points], New York [2.2], Hawaii [1.6], Illinois [1.3], Washington [1.3], New Jersey [1.2], Virginia [0.9], and Michigan [0.4]), and 12 exhibiting a significant decrease (South Dakota [−1.9], Idaho [−1.3], New Hampshire [−1.3], Wisconsin [−1.1], Maryland [−1.0], Nevada [−0.9], Ohio [−0.8], Mississippi [−0.6], Texas [−0.6], Florida [−0.5], Georgia [−0.4], and Indiana [−0.4]). The contributions of walking, bicycling, and taking transit also varied by state. Conclusion Active commuting remains relatively rare across states. States pursuing initiatives to support active transportation may consider using ACS to monitor and evaluate changes in active commuting.

Abstract
Engaging in regular physical activity is one of the most important things people can do to improve their cardiovascular health; however, population levels of physical activity remain low in the United States. Effective population-based approaches implemented in communities can help increase physical activity among all Americans. Evidence suggests that built environment interventions offer one such approach. These interventions aim to create or modify community environmental characteristics to make physical activity easier or more accessible for all people in the places where they live. In 2016, the Community Preventive Services Task Force released a recommendation for built environment approaches to increase physical activity. This recommendation is based on a systematic review of 90 studies (search period, 1980-June 2014) conducted using methods outlined by the Guide to Community Preventive Services. The Community Preventive Services Task Force found sufficient evidence of effectiveness to recommend combined built environment strategies. Specifically, these strategies combine interventions to improve pedestrian or bicycle transportation systems with interventions to improve land use and environmental design. Components of transportation systems can include street pattern design and connectivity, pedestrian infrastructure, bicycle infrastructure, and public transit infrastructure and access. Components of land use and environmental design can include mixed land use, increased residential density, proximity to community or neighborhood destinations, and parks and recreational facility access. Implementing this Community Preventive Services Task Force recommendation in communities across the United States can help promote healthy and active living, increase physical activity, and ultimately improve cardiovascular health.

Abstract
The Environmental Protection Agency created the National Walkability Index (Index) to compare and analyze walkability among US communities. Index elements include design, distance to transit, and diversity of land uses. Associations between the Index and walking behavior have not been examined. This study describes associations between the Index and transportation and leisure walking among US adults. Past week self-reported participation in transportation and leisure walking among adults (n = 33,672) was obtained from the 2015 Cancer Control Supplement of the National Health Interview Survey (NHIS) and analysis completed in 2019. Index scores were linked to NHIS data based on the respondent's residence and classified into least, below average, above average, and most walkable communities. Associations between Index categories and walking were examined with regression models. Overall, the Index was associated with a higher likelihood of walking, especially for transportation. Transportation walking was more common in areas with higher walkability (21.6%-51.6%, least to most walkable). Leisure walking was also more common with greater walkability (48.4%-56.5%, least to most walkable). Transportation and leisure walking by Index categories in urban areas were similar to the overall population; however, it was not associated with walking in rural areas. US adults living in more walkable areas report more transportation and leisure walking, especially among urban areas. Consistent with elements in the Index, associations were stronger for transportation than leisure walking. Findings support the use of the Walkability Index by researchers, professionals, and other relevant stakeholders as a viable indicator of walkability.

Abstract
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.

Abstract
BACKGROUND Daily step counts is an intuitive metric that has demonstrated success in motivating physical activity in adults and may hold potential for future public health physical activity recommendations. This review seeks to clarify the pattern of the associations between daily steps and subsequent all-cause mortality, cardiovascular disease (CVD) morbidity and mortality, and dysglycemia, as well as the number of daily steps needed for health outcomes. METHODS A systematic review was conducted to identify prospective studies assessing daily step count measured by pedometer or accelerometer and their associations with all-cause mortality, CVD morbidity or mortality, and dysglycemia (dysglycemia or diabetes incidence, insulin sensitivity, fasting glucose, HbA1c). The search was performed across the Medline, Embase, CINAHL, and the Cochrane Library databases from inception to August 1, 2019. Eligibility criteria included longitudinal design with health outcomes assessed at baseline and subsequent timepoints; defining steps per day as the exposure; reporting all-cause mortality, CVD morbidity or mortality, and/or dysglycemia outcomes; adults ≥18 years old; and non-patient populations. RESULTS Seventeen prospective studies involving over 30,000 adults were identified. Five studies reported on all-cause mortality (follow-up time 4-10 years), four on cardiovascular risk or events (6 months to 6 years), and eight on dysglycemia outcomes (3 months to 5 years). For each 1000 daily step count increase at baseline, risk reductions in all-cause mortality (6-36%) and CVD (5-21%) at follow-up were estimated across a subsample of included studies. There was no evidence of significant interaction by age, sex, health conditions or behaviors (e.g., alcohol use, smoking status, diet) among studies that tested for interactions. Studies examining dysglycemia outcomes report inconsistent findings, partially due to heterogeneity across studies of glycemia-related biomarker outcomes, analytic approaches, and sample characteristics. CONCLUSIONS Evidence from longitudinal data consistently demonstrated that walking an additional 1000 steps per day can help lower the risk of all-cause mortality, and CVD morbidity and mortality in adults, and that health benefits are present below 10,000 steps per day. However, the shape of the dose-response relation is not yet clear. Data are currently lacking to identify a specific minimum threshold of daily step counts needed to obtain overall health benefit.

Abstract
People with disabilities are at increased risk of chronic diseases, many of which physical activity can help prevent and manage. Certain environmental features can support or hinder participation in important activities like walking, particularly for people with disabilities. The purpose of this study is to examine differences in the prevalence of perceived neighborhood environmental supports and barriers for walking, by disability status, among US adults. Participants in the 2015 National Health Interview Survey Cancer Control Supplement (N = 15,280) reported their disability status (mobility disability, non-mobility disability, or no disability) and perceptions of neighborhood environmental supports (walkable roads, sidewalks, paths, trails; sidewalks on most streets; and walkable shops; transit; movies, libraries, churches; relaxing places) and barriers (traffic, crime, animals) for walking. Adjusted models conducted in 2019 included demographic characteristics. Prevalence of most supports was lower among adults with mobility or non-mobility disabilities versus no disability. For example, 54.9% and 57.5% of adults with mobility and non-mobility disabilities respectively reported sidewalks on most streets, compared to 64.1% of adults with no disability. After adjustment, significant differences remained when comparing adults with a mobility disability versus no disability for two supports (roads, sidewalks, paths, trails; relaxing places). All perceived barriers were significantly more common among adults with any disability versus no disability, regardless of adjustment. In the United States, adults with disabilities perceive fewer neighborhood environmental supports and more barriers for walking than their counterparts. Strategies that increase supports and address barriers for walking may help promote physical activity among adults with disabilities.

Abstract
IMPORTANCE It is unclear whether the number of steps per day and the intensity of stepping are associated with lower mortality. OBJECTIVE Describe the dose-response relationship between step count and intensity and mortality. DESIGN, SETTING, AND PARTICIPANTS Representative sample of US adults aged at least 40 years in the National Health and Nutrition Examination Survey who wore an accelerometer for up to 7 days ( from 2003-2006). Mortality was ascertained through December 2015. EXPOSURES Accelerometer-measured number of steps per day and 3 step intensity measures (extended bout cadence, peak 30-minute cadence, and peak 1-minute cadence [steps/min]). Accelerometer data were based on measurements obtained during a 7-day period at baseline. MAIN OUTCOMES AND MEASURES The primary outcome was all-cause mortality. Secondary outcomes were cardiovascular disease (CVD) and cancer mortality. Hazard ratios (HRs), mortality rates, and 95% CIs were estimated using cubic splines and quartile classifications adjusting for age; sex; race/ethnicity; education; diet; smoking status; body mass index; self-reported health; mobility limitations; and diagnoses of diabetes, stroke, heart disease, heart failure, cancer, chronic bronchitis, and emphysema. RESULTS A total of 4840 participants (mean age, 56.8 years; 2435 [54%] women; 1732 [36%] individuals with obesity) wore accelerometers for a mean of 5.7 days for a mean of 14.4 hours per day. The mean number of steps per day was 9124. There were 1165 deaths over a mean 10.1 years of follow-up, including 406 CVD and 283 cancer deaths. The unadjusted incidence density for all-cause mortality was 76.7 per 1000 person-years (419 deaths) for the 655 individuals who took less than 4000 steps per day; 21.4 per 1000 person-years (488 deaths) for the 1727 individuals who took 4000 to 7999 steps per day; 6.9 per 1000 person-years (176 deaths) for the 1539 individuals who took 8000 to 11 999 steps per day; and 4.8 per 1000 person-years (82 deaths) for the 919 individuals who took at least 12 000 steps per day. Compared with taking 4000 steps per day, taking 8000 steps per day was associated with significantly lower all-cause mortality (HR, 0.49 [95% CI, 0.44-0.55]), as was taking 12 000 steps per day (HR, 0.35 [95% CI, 0.28-0.45]). Unadjusted incidence density for all-cause mortality by peak 30 cadence was 32.9 per 1000 person-years (406 deaths) for the 1080 individuals who took 18.5 to 56.0 steps per minute; 12.6 per 1000 person-years (207 deaths) for the 1153 individuals who took 56.1 to 69.2 steps per minute; 6.8 per 1000 person-years (124 deaths) for the 1074 individuals who took 69.3 to 82.8 steps per minute; and 5.3 per 1000 person-years (108 deaths) for the 1037 individuals who took 82.9 to 149.5 steps per minute. Greater step intensity was not significantly associated with lower mortality after adjustment for total steps per day (eg, highest vs lowest quartile of peak 30 cadence: HR, 0.90 [95% CI, 0.65-1.27]; P value for trend = .34). CONCLUSIONS AND RELEVANCE Based on a representative sample of US adults, a greater number of daily steps was significantly associated with lower all-cause mortality. There was no significant association between step intensity and mortality after adjusting for total steps per day.

Abstract
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.

Abstract
PURPOSE Wearable activity monitors (wearables) have generated interest for national physical activity (PA) surveillance; however, concerns exist related to estimates obtained from current users willing to share data. We examined how limiting data to current users who are willing to share data associated with PA estimates in a nationwide sample. DESIGN Cross-sectional web-based survey. SETTING US adults. SUBJECTS In total, 942 respondents. MEASURES The 2018 Government & Academic Omnibus Survey assessing current wearable use, willingness to share data with various people or organizations, and PA levels. ANALYSIS Estimated the prevalence of current wearable use; current users' willingness to share data with various people or organizations; and PA levels overall, among current users, and among current users willing to share their data. RESULTS Overall, 21.7% (95% confidence interval [CI]: 19.1-24.5) of US adults reported currently using a wearable. Among current users, willingness to share ranged from 40.1% with a public health agency to 76.3% with their health-care provider. Overall, 62.2% (95% CI: 58.9-65.3) of adults were physically active. These levels were similar between current users (75.0%, 95% CI: 68.3-80.7) and current users willing to share their data (75.3%, 95% CI: 67.9-81.5). CONCLUSION Our findings suggest that using data from wearable users may overestimate PA levels, although reported willingness to share the data may not compound this issue.

Abstract
PURPOSE Step It Up! The Surgeon General's Call to Action to Promote Walking and Walkable Communities (Call to Action) presents goals and supporting strategies to promote walking. We assessed the presence and prioritization of 4 community supports for walking related to the goals of the Call to Action from the perspective of US adults. DESIGN Cross-sectional web-based survey. SETTING US adults. PARTICIPANTS A total of 4043 respondents. MEASURES SummerStyles 2016 survey assessing the reported presence and prioritization of 4 community supports for walking. ANALYSIS Estimated prevalence of the presence of supports overall and by demographic characteristics, and prevalence and adjusted prevalence ratios of their prioritization. RESULTS The most commonly reported community supports for walking were access to walkable locations (46.5%) and safe streets (29.2%), followed by walking groups (12.9%) and promotional campaigns (9.6%). Access to walkable locations (60.0%) and safe streets (50.6%) were most often prioritized by respondents, followed by promotional campaigns (23.6%) and walking groups (18.8%). Many differences in prioritization by demographic characteristics remained significant after adjusting for presence and other demographic characteristics, such as increased prioritization of all supports with older age groups. CONCLUSIONS Presence and prioritization of community supports for walking varied widely by type of support and by demographic characteristics. Opportunities exist to improve access and public sentiment related to these supports to promote walking in the United States.
