BACKGROUND: Temperament activity level can serve as a proxy for nondeliberate activity and an important part of overall energy expenditure. However, little is known about any association between temperament activity level and children's levels of moderate- to vigorous-intensity physical activity. We examined whether temperament activity level in young children is associated with moderate- to vigorous-intensity physical activity later in childhood and midadolescence. We also assessed if parenting behaviors moderate any association...

BACKGROUND: Physical inactivity and excess adiposity are thought to be detrimental to physical and cognitive health. However, implications of these interrelated health factors are rarely examined together, consequently, little is known regarding the concomitant contribution of physical activity and adiposity to cognition. METHODS: Bivariate correlations and hierarchical linear regressions were conducted among a sample of adults between 25-45 years (N= 65). Attentional inhibition was assessed using an Eriksen Flanker task...

BACKGROUND: Physical activity has been found to alleviate mental health problems and could be beneficial for at-risk populations, such as transgender people. This study had three aims. First, to explore the amount of physical activity that treatment seeking transgender people engage in, and to compare this to matched cisgender people. Second, to determine whether there was a difference in physical activity depending on cross-sex hormone use. Third, to determine factors which predict physical activity among treatment seeking transgender people...

BACKGROUND: Inclement weather and home environment can act as barriers to physical activity. However, it is unclear if they reduce the activity of persons participating in activity-promoting programs. METHODS: Data from a 6-month workplace financial incentives program were used to establish the association between meteorologic (temperature, rain, snow, and wind) and geographic factors (urban/rural home location and home distance from work) and moderate to vigorous physical activity (MVPA)...
