Assessment of Physical Activity and Cardiorespiratory Fitness in Medical Students

Introduction: Cardiorespiratory fitness is an indicator of cardiovascular health, usually expressed as VO2max. VO2max is the capacity of our body to transport and utilize oxygen during maximal exertion. The present study attempts to assess the level of physical activity and cardiorespiratory fitness in medical students and compare VO2max between physically active and insufficiently active students.
 Materials and Methods: An observational cross sectional study was conducted in 246 medical students (123 males and females each) of age between 18 to 23 years in National Medical College, Birgunj. After obtaining ethical clearance, screening was done with American College of Sports Medicine participants screening questionnaire. Students were classified as physically active and insufficiently active by using Global Physical Activity Questionnaire. VO2max was calculated from recovery heart rate counted from fifth to twentieth second of recovery after step test. Finally, subjects were categorized into different level of cardiorespiratory fitness based on their VO2max values.
 Results: Present study found 33.6% of insufficiently physical active students. Females had higher prevalence of insufficient physical activity (40.6%) than males (26.8%). The VO2max of male and female was 46.79 ± 8.98 and 36.15 ± 4.66 ml/Kg/min respectively. Majority of female participants had ‘average’ VO2max whereas in male, distribution is almost equal in ‘excellent’, ‘good’ and ‘fair’ category.
 Conclusion: Around one-third of medical students did not meet the level of physical activity recommended by WHO for health. Majority of them had ‘average’ level of VO2max and those physically active had better cardiorespiratory fitness.

Barriers to physical activity and associated factors in public school teachers – an transversal epidemiological study

Introduction: Teachers have a high prevalence of insufficient physical activity (PA) levels. However, the barriers to the practice of PA in this population and their associated factors are still not established in the literature. Objective: To describe the barriers to PA and identify associated factors in public school teachers. Methods: The sample was composed of 246 teachers (45.2 ± 10.4 years, 76% women). Barriers to PA, socioeconomic status, work-related factors, and habitual level of PA were assessed by questionnaire. The PA level according to each reported barrier was compared by analysis of variance and the association between barriers for PA and the categories of independent variables was analyzed by binary logistic regression. Results: Lack of Time (LT) and laziness, tiredness, or discouragement (LTD) were the most widely reported barriers (36.2% and 35.0%, respectively). Obese teachers were more likely to report LTD (OR = 2.34, p < 0.05) and less likely to report no barrier to PA (OR = 0.07, p < 0.05), when compared with teachers with normal weight. Teachers who reported working 21-30 hours per week were more likely to report LTD than those who worked 20 hours or less per week (OR = 4.12, p < 0.05). Teachers with a moderate-to-low PA level in leisure-time and sports practice were more likely to report LTD as the main barrier to PA (OR = 2.53, p < 0.05 and OR = 2.29, p < 0.05; respectively). Conclusion: LT and LTD were the most frequently reported barriers to PA by teachers. LTD was associated with obesity, higher hours worked, and lower levels of PA in leisure-time and sports practice.

Current Status of Physical Activity in South Korea.

The health benefits of physical activity have been well established. However, more than a quarter of the adult population in the world is insufficiently active (not performing at least 150 minutes of moderate-intensity physical activity per week, 75 minutes of vigorous-intensity physical activity per week, or any equivalent combination of the two), and there has been little improvement since 2001. In South Korea, the prevalence of insufficient physical activity was 54.4% in adults and 94.1% in adolescents in 2020. There was continuous decrease in the prevalence of sufficient aerobic physical activity, from 58.3% in 2014 to 45.6% in 2020. However, daily duration of sedentary behavior increased from 7.5 to 8.6 hours in the same period. Interventions to promote physical activity are necessary in various fields including clinical and policy approaches. As physical activity has decreased during the coronavirus disease 2019 pandemic, safer and more effective strategies to promote physical activity are required.

Interaction of Hydration Status and Physical Activity Level on Early Renal Damage in Children: A Longitudinal Study.

BackgroundOptimal water intake positively affects various aspects of human physiology, especially renal function. Physical activity (PA) may have an impact on hydration status and renal health, but the interaction of hydration status and PA level on renal function is not well-studied in children.MethodsWe conducted four waves of urine assays in our child cohort (PROC) study from October 2018 to November 2019 in Beijing, China. We measured urinary specific gravity, β2-microglobulin (β2-MG), and microalbumin (MA) excretion to assess hydration status and renal damage in the context of PA level and other covariates among 1,914 primary school children. We determined the associations of renal damage with the interaction of hydration status and PA level using generalized linear mixed-effects models.ResultsThe prevalence of dehydration was 35.0%, 62.1%, 63.9%, and 63.3%, and the prevalence of insufficient PA was 86.2%, 44.9%, 90.4%, and 90.2% from wave 1 to wave 4 among 1,914 primary school children. From wave 1 to wave 4, the prevalence of renal tubular damage had a significant increasing trend of 8.8%, 15.9%, 25.7%, and 29.0% (Z = 16.9, P < 0.001), while the prevalence of glomerular damage revealed a declining trend of 5.6%, 5.5%, 4.4%, and 4.1% (Z = −2.4, P = 0.016). There were stable longitudinal associations of renal tubular and glomerular damage with hydration status (euhydration: OR = 0.50 and 0.33, respectively) but not with PA level. In multivariate analysis, significant interactions of hydration status and PA level were noted with renal tubular damage (β = 0.43, P = 0.014) and glomerular damage (β = 0.60, P = 0.047). Children with euhydration and insufficient PA were less likely to have renal tubular damage (OR = 0.46, 95% CI: 0.39, 0.53) or glomerular damage (OR = 0.28, 95% CI: 0.20, 0.39); children with euhydration and sufficient PA were also less likely to have renal tubular damage (OR = 0.57, 95% CI: 0.44, 0.75) or glomerular damage (OR = 0.47, 95% CI: 0.30, 0.74), adjusting for age, sex, BMI z-score, standardized SBP, sleep duration, computer/cell phone screen time, and fruit and vegetable intake.ConclusionChildren with euhydration and either sufficient or insufficient PA were less likely to have early renal damage. Adequate daily water intake for children is important, especially after PA.

Health Awareness in the Field of Physical Activity in Slovakia

Objectives:The aim of this study was to provide up-to-date information on the prevalence of insufficient physical activity in Slovaks according to gender and age in 2019. Design: Pilot study Participants: A cross-sectional survey conducted in 2019 (men n = 1,298; women n = 1,316) monitored 2,614 partici- pants in the age category 15 - 64 years from all over Slovakia. Methods:We statistically analyzed the questionnaire survey on Health Awareness in Slovakia using the Chi-square test and Fisher's test, in which the level of significance was determined p-value ≤ 0.05.Results:Young men preferred active sports compared to young women who preferred to spend time on social networks. Older men preferred light physical activity compared to older women, who preferred reading books and magazines. Conclusion:With increasing age, the performance of physical activity in Slovaks decreased.

Insufficient Physical Activity and Sedentary Behaviors among Medical Students during the COVID-19 Lockdown: Findings from a Cross-Sectional Study in Pakistan.

Background: The unprecedented COVID-19 pandemic has resulted in social distancing and isolation which leads to insufficient physical activity and thereby increases sedentary behaviors. Hence, this study aimed to assess the prevalence of insufficient physical activity and sedentary behaviors among medical students during the COVID-19 lockdown in Pakistan, and to determine their associated factors. Methods: A cross-sectional online survey was carried out among 407 medical students from the Punjab and Sindh provinces between May and June 2020. To collect data, an e-questionnaire was sent to obtain informed consent along with questions concerning socio-demographics as well as an International Physical Activity Questionnaires–Short Form (IPAQ–SF). Results: As per the IPAQ, almost five in ten participants were physically inactive (48.2%), and 45.2% reported sedentary behaviors. Participants with insufficient physical activity were more likely to report sedentary behaviors than their counterparts (AOR = 2.53; 95% CI = 1.66–3.85, p < 0.001). The odds of insufficient physical activity were higher among the participants who did not strictly follow the COVID-19 preventive measures (AOR = 2.51; 95% CI = 1.35–4.69, p = 0.004); similarly, there were increased odds of sedentary behaviors observed among participants within a normal weight range compared to those who were underweight (AOR = 2.69; 95% CI = 1.76–4.11, p < 0.001). Conclusions: Insufficient physical activity and sedentary behavior are prevalent among medical students in Pakistan during the COVID-19 pandemic. These findings indicate the importance of establishing tailored policies and programs to encourage young adults to engage in physical activity.

Development of a School-Based Physical Activity Intervention Using an Integrated Approach: Project SMART.

Physical activity (PA) is a health-protective factor with multiple benefits for school-age children, yet only 22% of children and adolescents living in the United States (United States) accrue the recommended amount of moderate to vigorous PA. Given the prevalence of insufficient PA among children, promoting and providing PA opportunities during the school day, especially when integrated into the curriculum and linked to the learning standards, is essential for children. The purpose of this paper is to describe the procedure for the development of a school-based PA program using an integrated approach through the modified intervention mapping protocol (IMP). A total of 22 physical education teachers and 167 children from five different elementary schools were involved in the process. The procedure includes the Self-Determination Theory (SDT) that provides a theoretical framework that plays a vital role in motivating students to have a physically active lifestyle. This study applied SDT and IMP to develop and pilot a PA intervention called Project SMART using an integrative community participatory approach. As a pilot PA intervention, Project SMART is an online educational game where the students navigate a virtual journey across the United States A class’s aggregate PA propels the students on their journey, where standards-based modules are unlocked to achieve STEM (science, technology, engineering, and math) and social-emotional learning outcomes while gaining an understanding of the importance of health behaviors and opportunities to habitually engage in healthy decision-making with the support of their peers. Although initially labor intensive for the researchers, the process of tailoring the intervention to the children’s contextual and cultural needs has implications for all theoretically grounded and evidence-based PA interventions.

Physical inactivity and its predictors among adolescents in Saudi Arabia: A cross-sectional comparison between cities with and without a Healthy Cities Program.

Objectives:To estimate the prevalence of insufficient physical activity and excessive screen time among adolescents living in cities participating in the Healthy Cities Program (HCP) and cities not running the program in the Qassim region of Saudi Arabia.Methods:We surveyed 1133 adolescents from the Qassim region using systematic random sampling between April and September 2017. Multivariable logistic regression analyses were conducted to investigate the predictors of insufficient levels of PA and excessive screen time.Results:The prevalence of <60 minutes of moderate- to vigorous-intensity physical activity/day was 82.4% and <3 days of vigorous intensity physical activity/week among adolescents was 59%. There was no significant association between living in healthy cities (HCPs) and insufficient levels of physical activity. The odds of excessive screen time were higher in HCPs than in cities not running the program (NHCPs) (OR: 1.49). The odds of insufficient daily PA (OR: 2.19) are higher among girls than boys. Increasing age is positively associated with insufficient weekly PA (OR: 1.19). The prevalence of excessive recreational screen time is 84.6% with higher odds in HCPs than in NHCPs (OR: 1.51).Conclusion:Our findings report a lack of evidence of any impact of the HCP on adolescents’ physical activity behaviors. This outcome warrants a further in-depth evaluation of the process and outcomes of the HCP in Saudi Arabia.

Prevalence of and factors associated with insufficient physical activity among adolescents: evidence from a nationwide survey in Bangladesh

The World Health Organization set a target of a 15% relative reduction in the prevalence of insufficient physical activity (IPA) by 2025 among adolescents and adults globally. In Bangladesh, there are no national estimates of the prevalence of IPA among adolescents. The aim of this study was to estimate the prevalence of and risk factors associated with IPA among adolescent girls and boys. Data for 4865 adolescent girls and 4907 adolescent boys, collected as a part of a National Nutrition Surveillance in 2018-19, were analysed for this study. A modified version of the Global Physical Activity Questionnaire (GPAQ) was used to collect physical activity data. The World Health Organization recommended cut-off points were used to estimate the prevalence of IPA. Bivariate and multivariable logistic regression was performed to identify factors associated with IPA. Prevalences of IPA among adolescent girls and boys were 50.3% and 29.0%, respectively, and the prevalence was significantly higher among early adolescents (10-14 years) than late adolescents (15-19 years) among both boys and girls. The IPA prevalence was highest among adolescents living in non-slum urban areas (girls: 77.7%; boys: 64.1%). For both boys and girls, younger age, non-slum urban residence, higher paternal education and increased television viewing time were significantly associated with IPA. Additionally, residing in slums was significantly associated with IPA only among the boys. Higher maternal education was associated with IPA only among the girls. This study identified several modifiable risk factors associated with IPA among adolescent boys and girls in Bangladesh. These factors should be addressed through comprehensive public health interventions to promote physical activity among adolescent girls and boys.

Changes in Sitting Time, Screen Exposure and Physical Activity during COVID-19 Lockdown in South American Adults: A Cross-Sectional Study.

The worldwide prevalence of insufficient physical activity (PA) and prolonged sedentary behavior (SB) were high before the coronavirus (COVID-19) pandemic. Measures that were taken by governments (such as home confinement) to control the spread of COVID-19 may have affected levels of PA and SB. This cross-sectional study among South American adults during the first months of COVID-19 aims to (i) compare sitting time (ST), screen exposure, moderate PA (MPA), vigorous PA (VPA), and moderate-to-vigorous PA (MVPA) before and during lockdown to sociodemographic correlates and (ii) to assess the impact of lockdown on combinations of groups reporting meeting/not-meeting PA recommendations and engaging/not-engaging excessive ST (≥7 h/day). Bivariate associations, effect sizes, and multivariable linear regressions were used. Adults from Argentina (n = 575) and Chile (n = 730) completed an online survey with questions regarding demographics, lifestyle factors, and chronic diseases. Mean reductions of 42.7 and 22.0 min./day were shown in MPA and VPA, respectively; while increases of 212.4 and 164.3 min./day were observed in screen and ST, respectively. Those who met PA recommendations and spent <7 h/day of ST experienced greatest changes, reporting greater than 3 h/day higher ST and more than 1.5 h/day lower MVPA. Findings from the present study suggest that efforts to promote PA to South American adults during and after COVID-19 restrictions are needed.

Social and Educational Sustainability of the Physical Education of Romanian Students and the Impact on Their Physical Activity Level

Nowadays, a descending trend concerning physical activity levels among youth has been recorded, as well as differences between males and females; more than half recorded a low level of the physical activity. The aim of this study was to investigate the social and educational sustainability of physical education and to determine the level of physical activity by using the International Physical Activity Questionnaire (IPAQ) short form for Romanian undergraduate and graduate students. In our study, we included students and applied the IPAQ short form anonymously. They gave their consent to use these personal data only for scientific purposes. Overall, two thirds of the subjects (according to the IPAQ scoring protocol) and more than half (according to the World Health Organization recommendation for physical activity) consider themselves to be active. The present study showed that there is a prevalence of insufficient physical activity among Romanian University students (around 40%). The situation seems to be better than in other countries, but in self-evaluation, many people tend to overestimate their potential. To avoid this aspect and gain some objectivity, it is better to use a gadget in order to measure the level of their physical activity.

Global trends in insufficient physical activity among adolescents: A pooled analysis of 298 population-based surveys with 1.6 million participants

Summary Background Physical activity has many health benefits for young people. In 2018, WHO launched More Active People for a Healthier World, a new global action on physical activity, including new targets of a 15% relative reduction of global prevalence of insufficient physical activity by 2030 among adolescents and adults. We describe current prevalence and trends of insufficient physical activity among school-going adolescents aged 11–17 years by country, region, and globally. Methods We did a pooled analysis of cross-sectional survey data that were collected through random sampling with a sample size of at least 100 individuals, were representative of a national or defined subnational population, and reported prevalence of of insufficient physical activity by sex in adolescents. Prevalence had to be reported for at least three of the years of age within the 10–19-year age range. We estimated the prevalence of insufficient physical activity in school-going adolescents aged 11–17 years (combined and by sex) for individual countries, for four World Bank income groups, nine regions, and globally for the years 2001–16. To derive a standard definition of insufficient physical activity and to adjust for urban-only survey coverage, we used regression models. We estimated time trends using multilevel mixed-effects modelling. Findings We used data from 298 school-based surveys from 146 countries, territories, and areas including 1·6 million students aged 11–17 years. Globally, in 2016, 81·0% (95% uncertainty interval 77·8–87·7) of students aged 11–17 years were insufficiently physically active (77·6% [76·1–80·4] of boys and 84·7% [83·0–88·2] of girls). Although prevalence of insufficient physical activity significantly decreased between 2001 and 2016 for boys (from 80·1% [78·3–81·6] in 2001), there was no significant change for girls (from 85·1% [83·1–88·0] in 2001). There was no clear pattern according to country income group: insufficient activity prevalence in 2016 was 84·9% (82·6–88·2) in low-income countries, 79·3% (77·2–87·5) in lower–middle-income countries, 83·9% (79·5–89·2) in upper–middle-income countries, and 79·4% (74·0–86·2) in high-income countries. The region with the highest prevalence of insufficient activity in 2016 was high-income Asia Pacific for both boys (89·0%, 62·8–92·2) and girls (95·6%, 73·7–97·9). The regions with the lowest prevalence were high-income western countries for boys (72·1%, 71·1–73·6), and south Asia for girls (77·5%, 72·8–89·3). In 2016, 27 countries had a prevalence of insufficient activity of 90% or more for girls, whereas this was the case for two countries for boys. Interpretation The majority of adolescents do not meet current physical activity guidelines. Urgent scaling up of implementation of known effective policies and programmes is needed to increase activity in adolescents. Investment and leadership at all levels to intervene on the multiple causes and inequities that might perpetuate the low participation in physical activity and sex differences, as well as engagement of youth themselves, will be vital to strengthen the opportunities for physical activity in all communities. Such action will improve the health of this and future young generations and support achieving the 2030 Sustainable Development Goals. Funding WHO.

Levels and Correlates of Physical Activity in Rural Ingwavuma Community, uMkhanyakude District, KwaZulu-Natal, South Africa.

Physical activity, among others, confers cardiovascular, mental, and skeletal health benefits to people of all age-groups and health states. It reduces the risks associated with cardiovascular disease and therefore, could be useful in rural South Africa where cardiovascular disease (CVD) burden is increasing. The objective of this study was to examine levels and correlates of physical activity among adults in the Ingwavuma community in KwaZulu-Natal (KZN). Self-reported data on physical activity from 392 consenting adults (female, n = 265; male, n = 127) was used. We used the one-sample t-test to assess the level of physical activity and a two-level multiple linear regression to investigate the relationship between total physical activity (TPA) and independent predictors. The weekly number of minutes spent on all physical activities by members of the Ingwavuma community was 912.2; standard deviation (SD) (870.5), with males having 37% higher physical activity (1210.6 min, SD = 994.2) than females (769.2, SD = 766.3). Livelihood activities constituted 65% of TPA, and sport and recreation contributed 10%. Participants without formal education (20%), those underweight (27%), and the obese (16%) had low physical activity. Notwithstanding this, in general, the Ingwavuma community significantly exceeded the recommended weekly time on physical activity with a mean difference of 762.1 (675.8–848.6) minutes, t (391) = 17.335, p < 0.001. Gender and age were significant predictors of TPA in level 1 of the multiple regression. Males were significantly more active than females by 455.4 min (β = −0.25, p < 0.001) and participants of at least 60 years were significantly less active than 18–29-year-olds by 276.2 min (β = −0.12, p < 0.05). Gender, marital status, and health awareness were significant predictors in the full model that included education level, employment status, body mass index (BMI), and physical activity related to health awareness as predictors. The high prevalence of insufficient physical activity in some vulnerable groups, notably the elderly and obese, and the general poor participation in sport and recreation activities are worrisome. Hence we recommend health education interventions to increase awareness of and reshape sociocultural constructs that hinder participation in leisure activities. It is important to promote physical activity as a preventive health intervention and complement the pharmacological treatment of CVDs in rural South Africa. Physical activity interventions for all sociodemographic groups have potential economic gains through a reduction in costs related to the treatment of chronic CVD.

Association of physical performance impairments and limitations with insufficient physical activity among older adults in Brazil: results from the national health survey

Purpose: This study aimed to analyze the association between functional limitations variables and physical activity in older adults. Methods: A cross-sectional study, including 10,446 older adults aged 60 years or more who participated in the National Health Survey, 2013. The outcome variable was physical activity in the past 90 days and the explanatory variables were functional limitations, such as impairments in basic and instrumental activities of daily living, severe fall, use of walking aids, and chronic problems in the spine. Logistic regression was performed to obtain odds ratios (OR) and respective confidence intervals (95%), using the program Stata 13.1. Results: The prevalence of insufficient physical activity was 85.9% (95%CI: 85.2–86.6) and the highest odds were among older adults with two or more impairments in basic activities (OR: 2.98, 95%CI: 2.11–4.22), severe fall (OR: 1.52, 95%CI: 1.01–2.32), and use of walking device (OR: 4.65, 95%CI: 2.45–8.80). Conclusions: The prevalence of insufficient physical activity was high and multifactorial, allowing the identification of profiles of greater vulnerability, which should be considered regarding the direction of public policies for rehabilitation interventions directed at the functional performance of older adults.

Prevalence of and Factors Associated with Insufficient Physical Activity Among Adolescents: Evidence from the National Nutrition Surveillance Study

Abstract Objectives The World Health Organization (WHO) set a target of 15% relative reduction of the prevalence of insufficient physical activity (IPA) by 2025 among adolescents and adults globally. In Bangladesh, there is no national estimates of the prevalence of IPA among adolescents. In the recently completed round of the national nutrition surveillance (NNS 2018–2019), we aimed to estimate the prevalence and risk factors associated with IPA among adolescent girls and boys. Methods NNS was conducted in 57 rural, 15 urban and 10 slum clusters selected using multistage cluster sampling. In these clusters, we collected data from 4732 adolescent girls and 4761 adolescent boys. We used Global Physical Activity Questionnaire to collect physical activity (PA) data. The WHO recommended cut off points for IPA (5–17 years: &amp;lt;300 minutes of moderate to vigorous-intensity PA weekly; 18–19 years: &amp;lt;150 minutes of moderate intensity PA weekly or &amp;lt;75 minutes of vigorous-intensity PA weekly) were used to estimate the prevalence of IPA. Bivariate and multivariable logistic regression were performed to identify factors associated with IPA. Results Prevalence of IPA among girls and boys were 50.6% and 29.4%, respectively and the prevalence was significantly higher among early adolescents (10–14 years) than late adolescents in both boys and girls. The IPA prevalence was the highest among the adolescents living in non-slum urban areas (girls: 77.9% and boys: 64.6%). The IPA prevalence in slum areas was 36.6% for girls and 34.0% for boys; and in rural areas was 50.0% for girls and 28.2% for boys. For both girls and boys, age group, occupation and &amp;gt;6 hours of sitting per day were associated with IPA. Place of residence, consumption of fruits and vegetables, education and paternal occupation were associated with IPA only among the boys. On the other hand, maternal and paternal education and overweight/obesity were associated with IPA only among the girls. Conclusions One in every two adolescent girls and one in every three adolescent boys do not meet the WHO recommended level of PA in Bangladesh. This study identified several modifiable factors associated with IPA among adolescent boys and girls and these factors should be addressed through comprehensive public health interventions in order to improve adolescent health in Bangladesh.

Enabling and disabling behaviors in the social environment are associated with physical Activity of older people in the Netherlands

BackgroundAlthough research clearly shows that physical activity has significant health benefits and contributes to the prevention of chronic disease onset, the vast majority of the world’s population is insufficiently physically active, and the prevalence of insufficient physical activity is greatest in the population of older adults. The social environment may play an important role in shaping health behaviors, we however, lack knowledge regarding the exact influence of the social environment on older persons’ physical activity levels. This research therefore aims to identify the relationships of physical activity to enabling and disabling behaviors in the social environment among older people in the Netherlands.MethodsParticipants were randomly sampled from the Rotterdam municipality register and stratified by age group (70–74, 75–79, 80–84, and ≥ 85 years) and neighborhood (district). Of 2798 respondents, 1280 (46%) returned filled-in questionnaires. The Perceived Social Influence on Health Behavior (PSI-HB) instrument was used to assess the degree to which individuals’ health behavior is influenced by those around them. Respondents were additionally asked about enabling and disabling behaviors in their social environments and how many days per week they were physically active. Physical activity scores ranged from 0 (not being physically active for 30 min a day at all during the week) to 7 (being physically active every day of the week). Respondents with a score of ≥5 were considered to be physically active and those with a score of < 5 as physically inactive.ResultsResults revealed that increasing age significantly contributed to physical inactivity within this older population. Lower educational level significantly decreased the odds of physical activity. After controlling for background characteristics results show enabling behaviors and utilitarian social influence significantly increased the odds of physical activity while disabling behaviour of the social environment contributed to physical inactivity. No significant associations were found with perceived social influence aspects value-expressive influence and informational influence.ConclusionActual enabling and disabling behaviors of actors in older people’s social environments seem relevant for their physical activity levels, in positive and negative ways. In promoting active aging, consideration of the role of the social environment and ensuring that it is supportive of older people’s physical activity are important.
