To assess whether changes in physical activity and sedentary behaviour during the COVID-19 lockdown are associated with changes in mental and physical health. Observational longitudinal study. Participants living in France or Switzerland responded to online questionnaires measuring physical activity, physical and mental health, anxiety, and depressive symptoms. Paired sample t-tests were used to assess differences in physical activity and sedentary behaviour before and during lockdown. Multiple linear regressions were used to investigate associations between changes in physical activity and changes in mental and physical health during lockdown. 267 (wave1) and 110 participants (wave2; 2 weeks later) were recruited. Lockdown resulted in higher time spent in walking and moderate physical activity (~10min/day) and in sedentary behaviour (~75min/day), compared to pre COVID-19. Increased physical activity during leisure time from week 2 to week 4 of lockdown was associated with improved physical health (β=.24, p=.002). Additionally, an increase in sedentary behaviour during leisure time was associated with poorer physical health (β=−.35, p=.002), mental health (β=−.25, p=.003), and subjective vitality (β=−.30, p=.004). Ensuring sufficient levels of physical activity and reducing sedentary time can play a vital role in helping people to cope with a major stressful event, such as the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic may have detrimental effects on physical and mental health, but physical activity can help people to cope with stress, thereby mitigating its potential negative health consequences. In our study, we investigated whether changes in physical activity and sedentary behaviours are associated with changes in mental and physical health during the COVID-19 lockdown.

Objective. Habits, defined as well-learned associations between cues and behaviours, are essential for health-related behaviours, including physical activity (PA). Despite the sensitivity of habits to context changes, little remains known about the influence of a context change on the interplay between PA habits and behaviours. We investigated the evolution of PA habits amidst the spring COVID-19 lockdown, a major context change. Moreover, we examined the association of PA behaviours and autonomous motivation with this evolution.Design. Three-wave observational longitudinal design.

Narrative reviews indicate psychological and social benefits of sport participation for the ageing population. However, no quantitative synthesis of quantitative studies on this topic has been conducted yet. We evaluated the magnitude and heterogeneity of the effects of sport participation on psychosocial outcomes for middle-aged and older adults (>35 years). Ten databases were searched in July 2020. Quantitative studies (k=25) of middle-aged and older adults, measuring at least one psychosocial outcome of sport participation were included.Multilevel meta-analysis showed that the association between sport participation and psychosocial outcomes was small, yet significant. Moderation analyses revealed that the pooled effect differed according to outcome type; small to moderate associations were observed for social, positive psychological, perceived physical, and cognitive outcomes, but not for negative psychological outcomes. Risk of bias, assessed using the QualSyst tool, indicated low quality of evidence. Our findings suggest that sport participation is associated with multiple psychosocial benefits for middle-aged and older adults that appear invariant across participant-related and sport-related characteristics. We found no evidence of publication bias, but studies were underpowered and rated as low quality. Our review provides quantitative evidence for the psychosocial benefits of sport participation for adults, complementing existing qualitative research on this topic.

Summary Weight management interventions designed specifically for men have become more common, but the extent to which socioeconomic factors are considered in trials of these interventions is unclear. We synthesized study characteristics, methods, and reporting of interventions with a behavioral component for men that report weight as an outcome, to establish the extent to which socioeconomic factors are considered during intervention design, conduct, and reporting. A comprehensive search was conducted on Medline, Embase, PsycINFO, and CENTRAL for studies published from January 2000 to July 2021. Thirty‐six trials were included. Educational attainment (n = 24) was the most frequently reported socioeconomic characteristic, followed by working status (n = 14) and area level deprivation (n = 12). Seven studies did not report any socioeconomic characteristics. Most studies (n = 20) did not mention the socioeconomic profile of their samples in relation to study strengths or limitations. Few (n = 4) consulted with men from lower socioeconomic groups during intervention design. One study examined potential differential intervention effects across socioeconomic groups, with most not powered to do so. Recent feasibility trials (n = 3) targeting specific socioeconomic groups suggest a potential nascent towards a greater consideration of factors related to equity. To best inform public health policy related to health inequalities, greater consideration of socioeconomic factors is required in trials of men's weight management interventions.
