摘要

Background: To examine which school- and home-based factors at age 11 to 12 (6th grade, elementary school) predict physical activity (PA) and sedentary behavior (SB) at age 13 to 14 (8th grade, secondary school). Methods: Data at both time points were collected from 472 children (mean age baseline = 10.97, SD age = 0.41) and their parents. Children and parents completed self-reported questionnaires. Children's height and weight were measured and children wore a pedometer for 7 days. Results: Hierarchical regression analyses revealed that predominantly boys (beta = -.11), children with higher levels of pedometer-determined PA (beta = .44) and more parental logistic support (beta = .11) at age 11 to 12 displayed higher levels of pedometer-determined PA at age 13 to 14 (R-2 = 39.1%). Similar results emerged for self-reported moderate-to-vigorous PA (R-2 = 36.7%). Finally, lower levels of screen-based SB at age 13 to 14 (R2 = 32.5%) were most strongly related to lower levels of screen-based SB (beta = .41), a medium/high socioeconomic status (beta= -.18), and higher levels of parental PA explicit modeling (beta = -.18) at age 11 to 12. Conclusions: Children's PA/SB and the supportive role of parents at age 11 to 12 are strong predictors of PA and screen-based SB at age 13 to 14.
