Physical activity, screen time and self-rated health and mental health in Canadian adolescents.
Physical activity (PA) and screen time (ST) are associated with self-rated health (SRH) in adults; however, SRH has been less studied among youth, and information about self-rated mental health (SRMH) is lacking. This study examined the associations of PA and ST with SRH and SRMH among adolescents. ⋯ PA and ST are independently associated with health perceptions among Canadian adolescents. Interventions should consider health perceptions in addition to biomedical outcomes.

Gender disparities among the association between cumulative family-level stress & adolescent weight status.
To investigate precursors to gender-related obesity disparities by examining multiple family-level stress indices. ⋯ Different family-level stress indices are associated with the weight status of female and male adolescents. Combining types of family-level stress into one cumulative index appears to mask these differences.

Factors influencing the disconnect between self-perceived health status and actual health profile: implications for improving self-awareness of health status.
Self-perceived health is an often used proxy measure for disease and health behavior status. Due to its convenience in clinical and epidemiological contexts, it is of interest to examine factors that may help to explain the potential disconnect between perceived and actual health, which was the purpose of this study. ⋯ Targeted public health and educational messages to young adults, non-Hispanic Blacks, and those with a higher SES may be needed to help prevent discrepancies between perceived and actual health. Preventing this disconnect may help to, for example, improve individual health awareness, and ultimately, improve health outcomes.

Prospective association of vitamin D with frailty status and all-cause mortality in older adults: Results from the KORA-Age Study.
To assess the prospective association of serum 25-hydroxyvitamin D [25(OH)D] levels with frailty status and all-cause mortality in a cohort of community-dwelling participants of the population-based KORA [Cooperative Health Research in the Region of Augsburg]-Age Study. ⋯ Very low 25(OH)D levels were independently associated with incident pre-frailty, pre-frailty/frailty combined and all-cause mortality.

Is change in availability of sports facilities associated with change in physical activity? A prospective cohort study.
We examined whether change in distance to or number of sports facilities is related to change in metabolic equivalent task (MET) hours/week. ⋯ An increase in distance to and decrease in number of sports facilities were associated with a decrease in physical activity suggesting that changes in availability of facilities may affect physical activity levels.
