BACKGROUND: Temperament activity level can serve as proxy for non-deliberate 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 (MVPA). We examined whether temperament activity level in young children is associated with MVPA later in childhood and mid-adolescence. We also assessed if parenting behaviors moderate any association...

BACKGROUND: Gender differences in physical activity trajectories during adolescence are well-documented, yet little research has examined whether the determinants of these trajectories vary by child's gender. This study is one of few prospective examinations of gender differences in the influences of psychosocial and socioenvironmental factors on changes in objectively measured PA. METHODS: Students and parents from elementary and middle schools located in two school districts in South Carolina were enrolled in a prospective cohort study of changes in children's PA from elementary to middle school...

BACKGROUND: Recess and physical education time continues to diminish, creating a need for additional physical activity opportunities within the school environment. The use of school gardens as a teaching tool in elementary science and math class has the potential to increase the proportion of time spent active throughout the school day. METHODS: Teachers from four elementary schools agreed to teach one math or science lesson per week in the school garden. Student physical activity time was measured with ActiGraph GT3X accelerometers on three garden days and three no garden days at each school...
