背景：儿童和青少年时期身体活动（PA）减少，女性的PA水平明显低于男性，尤其是在青少年时期。学校是实施旨在促进女孩和年轻妇女PA的干预措施的有吸引力的环境，但很少有研究测试这种干预措施的持续效果。设计:横断面。数据收集于2002-2003年，分析于2006-2007年。设置/参与者：22所高中1594名青春期女生。干预：干预，生活方式教育促进活动计划（LEAP），旨在通过改变教学实践和改变学校环境两种途径增加九年级女孩的体育活动。这项研究（LEAP 2）调查了干预的影响在女孩进入12年级时保持的程度。主要观察指标：每天进行30分钟剧烈身体活动的次数。结果：最充分实施和维持干预的干预学校的女孩比其他学校的女孩更有可能平均每天参加一个或多个剧烈体育活动（p=0.04，优势比=1.49,95%置信区间=1.01-2.20）。结论：全面实施和维持的综合体育活动干预可以提高高中女生参与剧烈体育活动的程度。
Background: Physical activity (PA) decreases during childhood and adolescence, and PA levels are significantly lower in females than males, particularly during adolescence. Schools are attractive settings in which to implement interventions designed to promote PA in girls and young women, but few studies have tested the sustained effects of such interventions.Design: Cross-sectional. Data were collected in 2002-2003 and analyzed in 2006-2007.Setting/participants: 1594 adolescent girls in 22 high schools.Intervention: The intervention, Lifestyle Education for Activity Program (LEAP), was designed to increase physical activity in 9th-grade girls through two channels: changes in instructional practices and changes in the school environment. This study (LEAP 2) examined the extent to which effects of the intervention were maintained when the girls were in the 12th grade.Main outcome measures: Number of 30-minute blocks per day of vigorous physical activity.Results: Girls in the intervention schools that most fully implemented and maintained the intervention were more likely than girls in the other schools to participate in an average of one or more blocks of vigorous physical activity per day (p=0.04, odds ratio=1.49, 95% confidence interval=1.01-2.20).Conclusions: A comprehensive physical activity intervention that is fully implemented and maintained can increase participation in vigorous physical activity by high school girls.
