背景：青春期体力活动水平低和久坐行为高是令人担忧的问题。社会人口、发育、环境和心理因素可能相关，但这些行为的相关性可能有所不同。目的：调查大量 12 岁男孩和女孩样本中体力活动和久坐行为的多维相关性。方法：对来自 36 所学校的 2,578 名男孩和 1, 742 名女孩进行横断面调查，按社会经济背景和学生性别进行分层（答复率为 84%）。获得了问卷评估以及身高和体重的客观测量结果。结果：过去一周剧烈体力活动的天数和久坐行为的时间不相关。在单变量分析中，种族、社会经济因素、发育阶段、环境因素和心理变量与体力活动和久坐行为相关。在多元回归中，少数族裔、来自贫困家庭的学生以及有品行问题的学生的久坐行为更为严重。发育较先进且有情绪症状的女孩也有更多的久坐行为。剧烈的体力活动与良好的自评健康、亲社会心理特征以及（男孩）情绪低落症状相关。结论：需要采用多维方法来了解青春期早期身体活动的背景，因为多个领域的因素都是相关的。在这个年龄段，体力活动和久坐行为的相关性是明显的，而且也存在重要的性别差异。
Background: Low levels of physical activity, and high levels of sedentary behavior during adolescence are a cause for concern. Sociodemographic, developmental, environmental, and psychological factors may be relevant, but the correlates of these behaviors may differ. Purpose: To investigate the multidimensional correlates of physical activity and sedentary behavior in a large sample of I I - to 12-year-old boys and girls. Methods: Cross-sectional survey of 2,578 boys and 1, 742 girls from 36 schools stratified by socioeconomic background and gender mix of students (84% response rate). Questionnaire assessments and objective measurements of height and weight were obtained. Results: Days of vigorous physical activity and hours of sedentary behaviors over the past week were uncorrelated. Ethnicity, socioeconomic factors, developmental stage, environmental factors, and psychological variables were associated with physical activity and sedentary behavior in univariate analyses. In multiple regression, sedentary behavior was greater in ethnic minority groups, in students from more deprived backgrounds, and in those with conduct problems. Girls who were more advanced developmentally and who reported emotional symptoms also engaged in more sedentary behaviors. Vigorous physical activity was associated with good self-rated health, prosocial psychological characteristics, and (in boys) with low emotional symptoms. Conclusions: A multidimensional approach to understanding the context of physical activity in early adolescence is needed because factors in several domains are relevant. The correlates of physical activity and sedentary behaviors are distinct in this age group, and there are also important gender differences.
