评估学校作为娱乐场所的可及性和适宜性，并确定它们是否与青春期少女的周末代谢当量加权中度至剧烈体力活动和体重指数（BMI）相关。在马里兰州、南卡罗来纳州、明尼苏达州、路易斯安那州、加州的少女活动试验（n=1556）中，和亚利桑那州2003年春季，我们访问了规定距离内的所有学校和公园，并记录了它们在星期六的设施和可达性。工作人员收集了每个女孩的身高和体重数据，并使用加速度计记录了周末代谢当量加权的中度到剧烈的身体活动。然而，在我们访问的星期六，三分之一的学校无法进入。学校被锁的社区主要是非白人，年龄较大，人口更稠密，社会经济地位较低。虽然有没有学校之间的联系，在星期六和周末代谢当量加权中度到剧烈的身体活动，锁定学校的数量与显着较高的身体质量指数。CONCLUSIONSThe缺乏代谢当量加权中度到剧烈的身体活动和学校之间的关系可能意味着，年轻的青春期女孩不确定学校的娱乐资源。然而，由于身体质量指数与学校封闭之间的关联，遏制肥胖流行的努力应该包括使学校更容易进入。
OBJECTIVESTo assess the accessibility and suitability of schools as recreational sites and to determine whether they are associated with young adolescent girls' weekend metabolic equivalent-weighted moderate-to-vigorous physical activity and body mass index (BMI).METHODSWe drew a half-mile (0.805 km) radius around the residences of participants in the Trial of Activity for Adolescent Girls (n=1556) in Maryland, South Carolina, Minnesota, Louisiana, California, and Arizona. We visited all schools and parks within the defined distance and documented their amenities and accessibility on Saturdays in Spring 2003. Staff gathered data on each girls' height and weight and used accelerometers to record weekend metabolic equivalent-weighted moderate-to-vigorous physical activity.RESULTSSchools represented 44% of potential neighborhood sites for physical activity. However, a third of schools were inaccessible on the Saturday we visited. Neighborhoods with locked schools were primarily non-white, older, more densely populated, and of lower socioeconomic status. Though there was no relationship between school accessibility on Saturdays and weekend metabolic equivalent-weighted moderate-to-vigorous physical activity, the number of locked schools was associated with significantly higher body mass index.CONCLUSIONSThe lack of relationship between metabolic equivalent-weighted moderate-to-vigorous physical activity and school accessibility may imply that young adolescent girls do not identify schools as recreational resources. However, due to the association between body mass index and locked schools, efforts to stem the obesity epidemic should include making schools more accessible.
