What explains the well-being benefits of physical activity? A mixed-methods analysis of the roles of participation frequency and social identification.

OBJECTIVE: Physical activity in a social setting is said to be associated with well-being because it provides opportunities for participants to form social relationships. However, there are inconsistent findings regarding the well-being benefits of participating in physical activity with others. To address this inconclusive evidence, we draw on the social identity approach to health and well-being to examine whether (a) the frequency of physical activity participation in a social setting and (b) the degree of social identification associated with it, have different relationships with participants' well-being. METHODS: We implemented a two-phase, mixed-methods design with members of women's only fitness clubs in Japan. In Study 1, we collected survey responses about social identification, life satisfaction, and eudaimonic well-being from 1118 members. The survey data were combined with respondents' objective participation data from a membership database. In Study 2, we interviewed a sample of club members to understand how the nature of social relationships differed depending on the degree of their social identification. RESULTS: Study 1 found that social identification with a fitness club, but not the frequency of attending the club for physical activity, was positively associated with members' well-being. Study 2 revealed that members with high social identification experienced more affective relationships with other members than those with medium or low identification. CONCLUSIONS: Our research provides quantitative and qualitative evidence supporting the association between social identification and the well-being benefits of physical activity in a social setting. It confirms the predictions of the social identity approach to health and well-being, demonstrating that people enjoy well-being benefits from physical activity participation when it is internalized as a meaningful definition of self.

Older Adults' Physical Activity and Healthcare Costs, 2003-2014.

INTRODUCTION: Research has documented the health benefits of physical activity among older adults, but the relationship between physical activity and healthcare costs remains unexplored at the population level. Using data from 50 U.S. states and the District of Columbia, this study investigates the extent to which physical activity prevalence is associated with healthcare costs among older adults. METHODS: Twelve-year state-level data (2003-2014) were obtained from 5 secondary sources (n=611). Healthcare costs were captured by Medicare Parts A and B spending. Fixed-effect models were estimated in 2019 to assess the relationship between the state-level physical activity prevalence and Medicare costs. The potential lagged associations were captured by lagged variables of physical activity prevalence (i.e., t-1, t-2, and t-3). RESULTS: Physical activity prevalence was not associated with Medicare costs occurring in the concurrent and subsequent year (p>0.05); however, the 2-year lagged variable (p=0.03) and the 3-year lagged variable (p=0.01) for physical activity prevalence were negatively associated with Medicare costs, indicating a time-lagged relationship. It was estimated that a 10 percentage point increase in physical activity prevalence in each state is associated with reduced Medicare Parts A and B costs of 0.4% after 2 years and 1.0% after 3 years. CONCLUSIONS: Results revealed a time lag effect highlighted by a delayed inverse relationship between state-level physical activity prevalence and healthcare costs among older adults. This evidence offers governments and communities new insights to guide policymaking on long-term public investment in physical activity intervention programs.

Enhancing Older Adults' Sense of Belonging and Subjective Well-Being Through Sport Game Attendance, Team Identification, and Emotional Support.

Objective: We investigate how (a) attendance at sport games and (b) identification with a sport team as fans (i.e., team identification) influence older adults' perceptions of emotional support, belonging, and subjective well-being (SWB). Method: An experimental pilot study was conducted with 50 older adults, followed by a main survey study administered to 534 older adults from various communities across the United States. Results: Pilot study results indicated that game attendance and team identification had a positive and significant influence on older adults' perceptions of emotional support from fellow team fans. These results were replicated in the main study, which also showed that older adults' perceived emotional support from fellow fans was positively associated with their sense of belonging which predicted their SWB. Discussion: The findings provide insights into how older adults may be engaged in meaningful forms of social life to help them maintain and enhance mental health.

Association between sporting event attendance and self-rated health: an analysis of multiyear cross-sectional national data in Japan.

BACKGROUND: This study examined the extent to which sporting event attendance is associated with self-rated health. Drawing from an economic model of health production and psychological research on the health benefits of psychosocial resources, sporting event attendance was hypothesized to have a positive relationship with self-rated health. METHODS: A two-level multilevel ordered logistic regression was used to analyze multiyear cross-sectional data collected from national surveys in Japan. RESULTS: The results demonstrate that, controlling for the effects of personal and environmental characteristics, sporting event attendance positively correlates with self-rated health over a 12-year period. Specifically, when compared to individuals who did not attend any sporting event during the past year, those who attended a sporting event were 33% more likely to indicate a higher level of self-rated health. CONCLUSIONS: These findings provide evidence for a positive association between sport spectatorship and the perception of general health and contribute to the literature examining the relationship between sport spectatorship and health outcomes.

Rate of Physical Activity and Community Health: Evidence From U.S. Counties.

BACKGROUND: Although previous studies supported the health benefits of physical activity, these studies were limited to individual-level research designs. Building upon a social-ecological model, we examined the relationship between physical activity and community health-the health status of a defined group of people-while accounting for the potential endogeneity of physical activity to health. METHODS: We obtained U.S. county-level data from the 2012 Behavioral Risk Factor Surveillance System survey and the 2014 County Health Ranking Database. We first conducted an ordinary least squares (OLS) regression analysis to examine the relationship between the rate of physical activity and community health measured by the average perceived health score for each county. We then conducted a 2-stage least squares (2SLS) regression analysis to investigate this relationship after accounting for potential endogeneity. RESULTS: Results from the OLS analysis indicated that the rate of physical activity was positively associated with community health. Results from the 2SLS analysis confirmed that the physical activity rate remained positively associated with community health. CONCLUSIONS: In line with the social-ecological model, our findings provide the first evidence for the health benefits of county-level physical activity. Our results support extant research that has shown relationships between physical activity and individual-level, health-related outcomes.
