BACKGROUND: Effects of health education (HE) on physical activity (PA) are limited. Also, HE fails to address people's personal barriers and social pressures. In contrast, "psychological inoculation" (PI) targets both topics. This research examined the effects of PI versus HE on PA-related barriers and on self-reported PA in 2 studies. METHODS: Randomized controlled trials were employed. Study 1 (N = 20) took place in Britain, while study 2 (N = 40) in Belgium, with nonphysically active participants...

BACKGROUND: Interventions to raise population physical activity generally show modest effects; one possible reason is that trends and determinants of moderate to vigorous physical activity (MVPA) differ between population subgroups. This study examined differences in trends and determinants of reported MVPA by ethnicity/race and sex in a 15-year longitudinal study. METHODS: Participants (n = 2092) in the Project Eating and Activity in Teens and Young Adults study were surveyed on MVPA behavior and potential determinants from adolescence to young adulthood...

BACKGROUND: Pacific Islanders experience an elevated risk of health conditions such as obesity and diabetes, which are related to a lack of physical activity (PA). However, little attention has been paid to understanding the determinants of PA and promoting PA among this racial/ethnic group in the United States. METHODS: We conducted focus group discussions with Tongan Americans, one of the major Pacific Islander groups in the United States, to gain a better understanding of their PA participation patterns, their barriers and facilitators, their attitudes toward PA, and their perceptions of how mobile technologies such as smartphones could help increase their PA levels...

BACKGROUND: LGBTQ+ (lesbian, gay, bisexual, transgender, queer, etc) persons are subject to elevated rates of chronic diseases and health concerns that can be addressed through regular participation in physical activity. However, LGBTQ+ adults experience unique challenges to engaging in physical activity. Subsequently, the aim of this study is to describe the dominant narratives related to the complex intersection of sexual orientation, gender identity, and physical activity. METHODS: A systematic search and scoping review of existing literature was conducted in June 2016...

OBJECTIVE: Muscular strength has been shown to inversely associate with mortality. The purpose of this study was to examine the association between muscular strength and residual-specific mortality among a national sample of US adults, which has yet to be investigated. Here, residual-specific mortality is identified as deaths not inclusive of the 9 leading causes of death as identified by the International Classification of Diseases, 10th revision. METHODS: Data from the 1999-2002 National Health and Nutrition Examination Survey were used (N = 2171 adults, aged 50-85 y)...
