Abstract
BACKGROUND
Providing after school activities is a community level approach for reducing the decline in physical activity of girls as they reach early adolescence.
PURPOSE
The purpose of this study was to examine psychosocial, environmental, and behavioral factors as potential mediators of after school physical activity in adolescent girls.
METHODS
We assessed objectively measured levels of physical activity occurring outside of school and potential predictors and mediators of activity in girls participating in the Trial of Activity in Adolescent Girls (TAAG).
RESULTS
We found that the TAAG intervention had a statistically significant and positive effect on out of school activity in the 2006 cohort. Self-efficacy, friends' social support, total social support, and difficulty getting to and from community activities mediated the level of moderate to vigorous physical activity in girls.
CONCLUSIONS
Parents, communities, and schools should provide and enhance opportunities outside of the school day for adolescents to be active. Reducing transportation barriers and enlisting social support appear to be key.
摘要
背景
为女孩提供课余活动是一种社区层面的方法，可以减少她们在进入青春期早期后活动量下降的情况。
目的
本研究旨在探讨青少年女孩校外体育活动的心理社会、环境和行为因素，作为潜在的中介因素。
方法
我们评估了参加青少年女孩活动试验（TAAG）的女孩在校外进行的身体活动的客观测量水平，以及活动的潜在预测因素和中介因素。
结果
我们发现，TAAG 干预对 2006 年队列中校外活动有统计学上显著和积极的影响。自我效能感、朋友的社会支持、总社会支持以及参加社区活动的困难程度，在女孩的中等到剧烈身体活动水平中起到了中介作用。
结论
家长、社区和学校应该在课外时间为青少年提供和增加积极活动的机会。减少交通障碍和争取社会支持似乎是关键。
