Independent, Stratified, and Joint Associations of Sedentary Time and Physical Activity With Cardiovascular Disease: A Systematic Review

Charles Phillipe de Lucena Alves, Otávio Amaral de Andrade Leão, Felipe Mendes Delpino, Gregore Iven Mielke, Ulf Ekelund, Eduardo Caldas Costa, and Inácio Crochemore-Silva

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.

Poor Activities of Daily Living Predict Future Weight Loss in Older Adults After Hospital Discharge—Secondary Analysis of a Randomized Trial

Hrafnhildur Eymundsdottir, Berglind S. Blondal, Ólöf G. Geirsdottir, and Alfons Ramel

This study examined whether participants with poor activities of daily living (ADLs) at hospital discharge had increased weight loss after 6 months of follow-up and whether nutrition therapy can prevent this weight loss. This dietary randomized controlled trial (N = 104) examined community-dwelling older adults (66–95 years) discharged from hospital and at risk for malnutrition, receiving either 6 months of nutrition therapy (intervention) or only standard care (control). ADL was assessed using seven questions on self-care based on the Katz et al.’s method. At discharge, 45 (43%), 36 (35%), and 23 (22%) had high, medium, and poor ADL, respectively, with no differences between the control and intervention groups according to chi-square test. Participants in the control group with poor ADL had significantly higher weight loss than participants with high ADL (age- and sex-adjusted analysis of covariance: 3.6 kg; 95% confidence interval [1.0, 6.1] kg, p = .007). No such difference was observed in the intervention group. Participants with poor ADL at hospital discharge develop lower body weight by around 3.5 kg 6 months later when compared with participants with high ADL. Receiving nutrition therapy could help older adults with poor ADL to maintain body weight after hospital discharge.

A Pre–Post Study Design Exploring the Potential Benefits of a Hiking Intervention for Active and Inactive Older Adults

Iris A. Lesser and Cynthia J. Thomson

Introduction: Physical activity (PA) is essential for healthy aging, yet PA levels are low in older adults. Group-based nature programming may be an ideal opportunity for engaging older adults in PA and improving health-related quality of life. Methods: Twenty-seven older adults, 55–75 years of age (n = 14 active and n = 13 previously inactive), enrolled in a biweekly 8-week hiking program. At baseline, participants completed online questionnaires on health-related quality of life, behavioral and psychological outcomes, and a one-mile walk test to assess cardiorespiratory fitness. Results: Average attendance was 81% in the previously inactive groups and 74% in the active group. There was a significant increase in the physical component of quality of life over time in the previously inactive group (p = .03, d = 0.71). Participants significantly improved their cardiorespiratory fitness (p = .003, d = 0.77) and competency (p = .005, d = 0.41) as assessed by the Basic Psychological Needs for Exercise Scale. The previously inactive group additionally increased their self-efficacy for exercise (p = .001, d = 1.43). Both active and previously inactive groups exercised at a similar relative intensity during the hikes based on heart rate; however, perceived exertion at the end of the hike on average was lower among active participants (p = .014). Conclusion: Group-based hiking for previously inactive older adults significantly improved physical health-related quality of life over an 8-week biweekly intervention. Hiking at an individualized pace may allow for hiking to be an appropriate PA program in previously inactive older adults.

Factors Associated With Leisure-Time Bicycling Among Adults in the United States: An Urban–Rural Comparison

Eugene C. Fitzhugh, Carissa Smock, Laura E. Balis, Jeanette Gustat, Debra Kellstedt, James N. Roemmich, Zachary Townsend, and Christiaan Abildso

Background: Bicycling is a healthy form of physical activity that can be performed by most adults as part of leisure-time (LT) activity. However, little is known about LT bicycling behaviors, especially in the rural areas of the United States. This study sought to contrast the prevalence and factors associated with LT bicycling in populations living in urban settings with those living in rural settings. Methods: The 2019 Behavior Risk Factor Survey, which contains information regarding LT physical activity behaviors among adults (N = 396,261) in the United States, was used to determine the prevalence, demographic profile, and likelihood of meeting the physical activity guidelines of LT bicyclists. The 2013 National Center for Health Statistics Urban/Rural Classification Scheme was used to classify respondents living in rural and urban settings. Results: Among US adults, 3.8% (95% CI, 3.7–3.9) reported LT bicycling activity, the sixth most common physical activity. Adults living in urban counties compared with rural counties had a greater prevalence of LT bicycling (3.9% vs 2.3%, respectively), with adults living in rural counties having a 34% lower probability of LT bicycling. Rural bicycling prevalence rates were lower across all demographics. Urban bicyclists, compared with rural bicyclists, cycled more months of the year. Overall, 85.5% of all bicyclists met the aerobic physical guidelines, with no differences between urban and rural bicyclists. Conclusions: Bicycling remains an important LT physical activity among adults in the United States. However, a rural–urban difference in the prevalence does exist for LT bicycling. The reasons for this disparity warrant further investigation.

Inequality in Physical Activity in Organized Group Settings for Children: A Cross-Sectional Study

Ann E. Rogers, Christopher S. Wichman, Michaela A. Schenkelberg, and David A. Dzewaltowski

Background: Adult-led organized settings for children (eg, classrooms) provide opportunities for physical activity (PA). The structure of setting time may influence inequalities (ie, unequalness) in the distribution of PA. This study examined differences in PA inequality by setting and time-segment purpose in time-segmented organized group settings for children. Methods: PA and setting meetings were assessed using accelerometer and video observation data from school, before-/after-school, and youth club groups (n = 30) for third- through sixth-grade children (n = 699) in 2 rural US communities. Meetings (n = 130) were time-segmented into smaller units (sessions; n = 835). Each session was assigned a purpose code (eg, PA). Accelerometer data were paired with the meetings and sessions, and the Gini coefficient quantified inequality in activity counts and moderate to vigorous PA minutes for each segment. Beta generalized estimating equations examined differences in PA inequality by setting and session purpose. Results: Activity count inequality was lowest (P < .05) during youth club meetings (Gini = 0.17, 95% CI, 0.14–0.20), and inequality in moderate to vigorous PA minutes was greatest (P < .01) during school (Gini = 0.34, 95% CI, 0.30–0.38). Organized PA sessions (Gini = 0.20, 95% CI, 0.17–0.23) had lower activity count inequality (P < .0001) than academic (Gini = 0.30, 95% CI, 0.27–0.34), enrichment (Gini = 0.31, 95% CI, 0.27–0.36), and nonactive recreation (Gini = 0.30, 95% CI, 0.25–0.34) sessions. Inequality in moderate to vigorous PA minutes was lower (P < .05) in organized PA (Gini = 0.26, 95% CI, 0.20–0.32) and free play (Gini = 0.28, 95% CI, 0.19–0.39) than other sessions. Conclusions: PA inequality differed by setting time structure, with lower inequality during organized PA sessions. The Gini coefficient can illuminate PA inequalities in organized settings and may inform population PA improvement efforts in rural communities.

Results From South Africa’s 2022 Healthy Active Kids’ Report Card on Physical Activity, Body Composition Proxies, and Nutritional Status in Children and Adolescents

Zingisa Z. Nyawose, Rowena Naidoo, Candice Christie, Susan Bassett, Dané Coetzee, Maya van Gent, Andries Monyeki, Philippe Gradidge, Christa Janse van Rensburg, Colleen Cozett, Marie Young, Wiedaad Slemming, Lumé Morrow, Anita Pienaar, Soezin Krog, Cheryl Walter, Aayesha Kholvadia, Monique De Milander, Niri Naidoo, and Estelle V. Lambert

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.

Lumbar Extensor Muscle Strength and Physical Performance in Community-Dwelling Older Adults: Findings From SarcoSpine Cohort

Dong Hyun Kim, Sohee Oh, Seungcheol Kim, and Sang Yoon Lee

Background: The lumbar extensor muscles (LEMs) play an important role in body posture and physical function in older adults. Because lumbar extensor strength decreases more rapidly than limb muscle strength with age, it should be evaluated to aid healthy aging. This study investigated the association between LEM strength and physical performance in community-dwelling older adults. Methods: This prospective observational cohort study of spinal sarcopenia (SarcoSpine) was conducted at a single center. One hundred and ten consecutive individuals who completed the baseline survey, including conventional sarcopenic indices, lumbar spine three-dimensional magnetic resonance imaging, isokinetic lumbar extensor strength, and physical performance tests (Short Physical Performance Battery, Berg Balance Scale, and Back Performance Scale [BPS]), were enrolled. A multivariate linear regression analysis was performed to determine the variables for evaluating their association with LEM strength. Results: Among the conventional sarcopenic indices, gait speed was significantly correlated with Short Physical Performance Battery results and Berg Balance Scale score in men and women. Handgrip strength was significantly correlated with the BPS score for both sexes. In the multivariable linear regression, age (β = −2.12, p < .01) and BPS score (β = −3.54, p = .01, R 2 = .29) were independent indicators of LEM strength. Conclusions: Our findings reveal the substantial association between LEM strength and BPS score in older women. The targeted intervention aimed at improving the LEMs strength would be needed to enhance physical performance in the aging population.

The Cotillion Community

Maria J. Veri and Diane L. Williams

The Amy Morris Homans Cotillion, held annually from 1982 to 2014, was a safe space for lesbian professionals in kinesiology, as well as a challenge and a disruption to the misogyny, homophobia, and heterosexism that pervaded the field in the mid- and late 20th century. In this article, we highlight the lived experiences of the broader Cotillion community. We conducted oral-history interviews with American Alliance for Health, Physical Education, Recreation and Dance (AAPHERD) convention attendees about their memories of the Cotillion and Pre-Cotillion. Through these stories, we convey the significance of these events for the women and lesbians in kinesiology/physical education departments who attended them. The article begins with descriptions of interviewees’ lives within the field, progresses to how attendees discovered and experienced the Cotillion and/or Pre-Cotillion, and then explores the impact of the Cotillion, both at AAPHERD and beyond the convention.

From the Closet to the Center

Diane L. Williams, Maria J. Veri, and Jackie Hudson

The Amy Morris Homans Cotillion and Pre-Cotillion created unique and liberatory spaces for many lesbian and allied women attending the American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) convention between 1982 and 2014. In this article, we draw on feminist and queer theories to consider the multiple meanings embedded in Cotillion goers’ lived experiences. Memories of planning and participating in these events linger for attendees decades later. The impact of attending ranged from lighthearted appreciation to profound gratitude. The Cotillion events disrupted the oppressive status quo at the AAHPERD convention and within kinesiology in favor of community building, joy, and the celebration of lesbian identities. We explore the disruption of heteropatriarchal norms and the creation of alternative community spaces to learn better from the past and to help create liberatory futures for practitioners and scholars in kinesiology.

Impact of Land Versus Water Environments on Orthostatic Hypotension in Older Adults: A Randomized Crossover Study

Emily Dunlap, Taha Alhalimi, Natalie McLaurin, and Hirofumi Tanaka

Background/Objectives: Orthostatic hypotension (OH) is a common condition among older adults that increases the risk of falls. The study objectives are to determine the influence of distinct environments (water vs. land) on OH and the consequent effects of walking in these environments in older adults. Additionally, we aimed to assess the differences in response between two groups: older adults with OH and those without OH. Methods: A randomized crossover design was utilized including one session involving water walking and the other session involving land walking, with a 1- to 3-day washout period. Orthostatic hemodynamic measurements were obtained before, immediately after, and 2 hr after a 15-min walking session. Two subgroups were formed for analysis: participants with OH (n = 14, 81 ± 7 years) and participants without OH (n = 11, 84 ± 7 years). Results: Compared with the land environment, an 86% reduction in the frequency of OH episodes was noted when the older adults were immersed in water. This reduction was accompanied by greater mean arterial pressure, while participants without OH showed no such changes. The frequency of OH episodes was similar when assessed immediately after emerging from the pool following water-based walking or after land-based walking. All participants exhibited elevated mean arterial pressure immediately after water-based walking, but not after land-based walking. Two hours after walking, all participants demonstrated similar mean arterial pressure and frequency of OH episodes, regardless of the environment. Conclusions: Water immersion resulted in a substantial reduction in the frequency of OH episodes among older adults. Additionally, the frequency of OH episodes was not affected by prior walking exercise in either environment. Significance/Implication: These findings underscore the safety and potential advantages of water-based exercise for older adults dealing with OH.
