我们检查了多水平变量和女孩体力活动之间的关系，以确定它们在不同的青少年年龄是否存在差异。青春期女孩活动试验的所有实地地点都有6年级(n=1576)和8年级(n=3085)的参与者。马里兰州的网站提供了11级样本(n=589)。调查问卷被用来获得人口统计和心理社会信息(个人和社会层面的变量)；身高、体重和三头肌皮皱来评估身体成分；学校层面的数据采访和调查；以及社区层面变量的地理信息系统和自我报告。通过加速计评估中等到剧烈的体力活动分钟数(MVPA)。使用混合模型(13个个人、5个社会、15个学校、12个邻里变量)来确定多层次关联。个人、社会、学校和社区层面的变量与MVPA相关，但在不同年级之间存在差异。在6年级和8年级，较低的体脂百分比，较高的朋友社会支持，以及较低的学校数学成绩与较高的MVPA相关。高体育活动自我效能感与11年级MVPA高相关。只有较低的体力活动障碍与所有年级的MVPA较高相关。MVPA是一种复杂的行为，具有流动的、多层次的关联，初中和高中的女孩之间存在不同的关联。
We examined associations among multilevel variables and girls’ physical activity to determine whether they vary at different adolescent ages. All field sites of the Trial of Activity for Adolescent Girls contributed participants from 6th (n = 1576) and 8th grades (n = 3085). The Maryland site contributed an 11th grade sample (n = 589). Questionnaires were used to obtain demographic and psychosocial information (individual- and social-level variables); height, weight, and triceps skinfold to assess body composition; interviews and surveys for school-level data; and geographical information systems and self-report for neighborhood-level variables. Moderate to vigorous physical activity minutes (MVPA) were assessed from accelerometers. Mixed models (13 individual, 5 social, 15 school, 12 neighborhood variables) were used to determine multilevel associations. Variables at individual, social, school, and neighborhood levels were associated with MVPA, but differed across grades. Lower percent body fat, higher social support from friends, and lower school math scores were associated with higher MVPA at 6th and 8th grade. Higher physical activity self-efficacy was associated with higher MVPA at 11th grade. Only lower physical activity barriers were associated with higher MVPA at all grades. MVPA is a complex behavior with fluid, multilevel correlates that differ among girls across middle and high school.
