Background: Hypertension is a significant risk factor for cardiovascular disease, with a higher prevalence among African Americans (AA) than other racial groups. The impact of community-based interventions on managing blood pressure (BP) in AA communities is not fully understood. The purpose of this review was to synthesize literature on community-based physical activity (PA) programs designed to manage BP in AA populations.

Methods: We conducted a scoping review by searching 4 databases (PubMed, CINAHL, MEDLINE, and APA PsycInfo) and reference lists of studies. Search terms included community PA, community-based, hypertension, high BP, AA, Black Americans, PA, and exercise. Inclusion criteria were studies (1) conducted in the United States and (2) published in English language from January 2013 to September 2023, with community-based interventions that included PA for BP management among AA aged ≥18 years.

Results: Search results yielded 260 studies, of which 11 met the inclusion criteria. BP decreased over time in studies that incorporated PA, faith-based therapeutic lifestyle changes with nutritional education. The duration of the PA interventions varied, with moderate to vigorous PAs implemented for 12 weeks or longer having a greater impact on BP management.

Conclusions: Evidence suggests that community-based PA programs can potentially reduce BP among AA. PA programs incorporating faith-based therapeutic lifestyle change with nutritional education appear to reduce BP. Practitioners should consider multicomponent community-based PA initiatives to improve BP outcomes in AA communities.

Background: In 2011, physical inactivity was described as the Cinderella risk factor for noncommunicable diseases. This metaphor was used to highlight the disjunct between the advancing evidence on physical inactivity as a risk factor for ill health, its high prevalence, and the paucity of global policy response or priority afforded to physical activity. This paper describes the strategic actions of the International Society for Physical Activity and Health (ISPAH) to raise the profile of physical activity as a global public health priority.

Methods: From 2008, ISPAH coordinated a long-term advocacy strategy to advance the status of physical activity and promote its presence as a priority within global health policy. The society employed an advocacy mix that reflected contemporary advocacy theory and models.

Results: Through 6 advocacy deliverables, aligned to the global calendar of United Nations and World Health Organization policy developments, ISPAH seized the opportunity to advance physical activity policy and strategies to inform global noncommunicable disease action planning and align with the Sustainable Development Goals. ISPAH's successful execution of global advocacy for physical activity highlights the importance of leadership, clear objectives, progressive action, timeliness, partnerships, and persistence.

Conclusion: As a result of strategic global advocacy since 2008, the field in 2024 is better positioned in relation to global professional mobilization, policy, and technical support for physical activity. However, despite impressive progress across more than 12 years, and the innovation of the Global Action Plan on Physical Activity, the work of global advocacy for physical activity is far from complete.

Background: Although the physical activities have demonstrated efficacy in improving physical self-perception, the findings of available studies in college students were conflicting. This review aimed to examine the effects of physical activity interventions on physical self-perception in college students.

Methods: Web of Science, PubMed, Cochrane Library, EBSCOhost, Embase, Scopus, CNKI, WanFang, and Chinese Technical Periodicals were searched from inception to April 2024. Studies were included if they were randomized controlled trials (RCTs) or non-RCTs (non-RCTs) that examined the effects of physical activity interventions on college students' physical self-perception. Random-effects models were used in meta-analyses to synthesize effect sizes.

Results: Forty studies (17 RCTs and 23 non-RCTs) with 4955 participants were included in this meta-analysis. Overall, physical activity interventions had small to moderate significant effect on physical self-worth (standardized mean difference [SMD] = 0.44, P < .00001), perceived sports competence (SMD = 0.60, P < .00001), perceived physical condition (SMD = 0.45, P < .00001), perceived physical strength (SMD = 0.53, P < .00001), and perceived body attractiveness (SMD = 0.54, P < .00001). Significant differences were observed in study design (P = .031-.039), intervention type (P = .003-.031), and intervention duration (P = .002-.036) for some aspects of physical self-perception, such as perceived physical strength and perceived body attractiveness.

Conclusions: Physical activity interventions have beneficial effects on physical self-perception in college students, especially those conducted for 12 weeks, 3 times or more per week, lasting 90 minutes or more per session. Large, high-quality RCTs are required to further confirm these findings.

Background: Given the emergence of climate change and health risks, this review examined potential relationships between varying indicators of climate change, movement behaviors (ie, physical activity [PA], sedentary behavior, and sleep), and health.

Methods: Seven databases were searched in March 2020, April 2023, and April 2024. To be included, studies must have examined indicators of climate change and at least one of the movement behaviors as either an exposure or a third variable (ie, mediator/moderator), and a measure of health as outcome. Evidence was summarized by the role (mediator/moderator) that either climate change or movement behavior(s) has with health measures. Relationships and directionality of each association, as well as the strength and certainty of evidence were synthesized.

Results: A total of 79 studies were eligible, representing 6,671,791 participants and 3137 counties from 25 countries (40% low- and middle-income countries). Of 98 observations from 17 studies that examined PA as a mediator, 34.7% indicated that PA mediated the relationship between climate change and health measure such that indicators of adverse climate change were associated with lower PA, and worse health outcome. Of 274 observations made from 46 studies, 28% showed that PA favorably modified the negative association between climate change and health outcome. Evidence was largely lacking and inconclusive for sedentary behavior and sleep, as well as climate change indicators as an intermediatory variable.

Conclusions: PA may mitigate the adverse impact of climate change on health. Further evidence is needed to integrate PA into climate change mitigation, adaptation, and resilience strategies.

Background: Adults with physical or intellectual disability are less active than those without disability.

Objective: To review literature regarding sport participation in adults with physical or intellectual disability. Specifically, to examine characteristics of available studies including participants, interventions, outcomes, and impact.

Methods: A scoping review was completed. Searches of 6 databases and a trial registry plus citation tracking were undertaken. Two independent reviewers screened items for eligibility and extracted data about the studies, participants, interventions, and outcomes. A single reviewer extracted data to quantify impacts of sport participation, classified as favorable, insignificant, or unfavorable.

Results: 164 studies involving 11,642 participants were included. Most studies (128/164) used a cross-sectional design. Most participants were men (81%) with physical disability (135/164), and spinal cord injury was the most prevalent underlying health condition (54%). Most studies evaluated a mix of sports (83/164) in a disability-specific context (159/164), with basketball or wheelchair basketball being the most common individual sport (28/164). Physical impairment was the most frequently reported outcome domain (85/334 results). Sports participation impact was classified as 55% favorable, 42% insignificant, and 3% unfavorable.

Conclusions: There were many favorable and few unfavorable outcomes for participation in sport for adults with physical or intellectual disability. More research is needed to address the evidence gaps of gender, health condition, and type of sport, and to use more rigorous research designs to evaluate the effects of sport participation. While new evidence is generated, we suggest adults with physical or intellectual disability be encouraged to engage in sport.

Background: Recent statistics highlight cardiovascular diseases (CVD) as a major global cause of death. This review examines the methodological approaches and the main results of independent, stratified, and joint association of sedentary time (ST) and physical activity (PA) on CVD outcomes.

Methods: We searched PubMed, Embase, Web of Science, and Scopus for prospective cohorts that examined the independent, stratified, or joint associations of ST and PA with CVD outcomes. Independent associations were defined as analyses mutually adjusted for PA and ST. Stratified associations were considered when there was a reference group in each stratum of PA or ST, and joint associations were defined by a single reference group for all other combined categories of ST and PA levels.

Results: Of 45 articles, 69% explored independent association of ST or PA on CVD outcomes, while 31% using a stratified/joint approach. Most studies used self-reports for ST and PA and focused on CVD mortality. Mutually adjusted analyses identified ST positively and PA inversely associated to CVD outcomes. Stratified studies showed higher ST's pronounced impact on CVD for lower PA levels. High PA mitigated but did not eliminate ST's negative impact. Joint analyses revealed highest CVD risk in those with both high ST and low PA, and elevated risk in various intermediate combinations.

Conclusions: Employing independent, stratified, and joint association approaches can yield distinct and complementary public health messages aimed at promoting cardiovascular health. Recommendations should aim to not only to encourage boosting PA levels, but also, concurrently decrease ST.

Background: Physical activity (PA) and nutrition in children have an impact on overall physical and mental well-being, cognitive, and social development. This study aims to report on the best current available evidence on PA, body composition proxies, and nutritional status of South African children and adolescents, based on the published findings between 2018 and 2022, which comprise the 2022 Healthy Active Kids South Africa Report Card.

Methods: A comprehensive literature search of online databases, along with hand searching and a gray literature search, was conducted based on PA, body composition proxies, and nutrition indicators defined, in part, by the Active Healthy Kids Global Alliance.

Results: Compared with the 2018 report card, there was an improvement in the majority of PA indicators which include overall PA (B-), active transportation (B-), physical fitness (B-), and government policy and programs (C). Body composition proxies and most of the nutrition indicators remained unchanged. The indicators that regressed from 2018 to 2022 included community and environmental influences (D), as well as participation in organized sport (D-).

Conclusions: Despite the apparent improvement in overall PA levels in children and adolescents, there is a lack of tangible evidence of actual implementation of policies and programs. There was also a lack of nationally representative data for most indicators. Overall, there is a need to identify intersectoral, equitable approaches for promoting PA and healthy eating in South African children and adolescents and ongoing monitoring and surveillance.

Background: Cognitively stimulating sedentary behavior (SB) may positively impact cognition. This study aimed to (1) describe participation across types of SB among older adults with and without cognitive impairment and (2) examine how baseline SB participation impacts cognition, longitudinally.

Methods: We used National Health and Aging Trends Study data from rounds 6 to 11 for cross-sectional and longitudinal analyses. Participants were 2244 community-dwelling older adults who were selected for the SB module in round 6. The SBs were categorized as active (eg, hobbies) and passive (eg, television). Participants were also categorized as having intact or impaired orientation, memory, and executive function based on tests of orientation, recall, and the clock-drawing test. We calculated descriptive statistics characterizing SB by cognitive status. Aim 2 involved competing risks proportional hazard models of participants with intact cognition (n = 1574) to identify associations between baseline SB and changes in cognition, moves to institutional care, and death over 6 years.

Results: Participants (40% ≥ 80 years, 55% female, 77% White non-Hispanic) averaged 8.75 (SD = 4.42) hours of daily SB, including 4.05 (SD = 2.32) hours of passive SB and 4.75 (SD = 3.13) hours of active SB. Active SB >3 hours per day was associated with a lower risk of impaired orientation (subdistribution hazard models = 0.60; P = .048) and memory (subdistribution hazard models = 0.62; P = .02). Baseline participation in passive SB did not impact the risk of having a change in cognition during rounds 7 to 11.

Conclusion: Cognitive decline was lower among older adults who participated in more active SB. Thus, type of SB should be considered in examining the impact on cognition.
