关于青少年朋友的实际身体活动和屏幕时间行为与个人行为的关系，我们知之甚少。确定青少年的身体活动和屏幕时间与他/她提名的朋友的身体活动和屏幕时间之间的关联。数据来自EAT 2010（青少年饮食和活动），这是一项大型横断面研究（n=2126），在2009-2010学年期间在明尼阿波利斯/圣保罗MN的20所中学和高中进行，并在2011年进行分析。每个参与者从学校名册中提名最多六个朋友，这些朋友的数据作为学校数据收集程序的一部分。身体活动和屏幕时间与以前使用和验证的问卷进行了评估。按性别分层的广义估计方程模型被用来评估青少年的身体活动和屏幕时间以及他们的朋友的身体活动和屏幕时间之间的关联。女性青少年的身体活动与他们的男性和女性朋友的身体活动有关，包括他们的男性和女性最好的朋友（所有p<0.05）。男性的体育活动与女性朋友的体育活动相关（p<0.03）。女性的屏幕时间与他们的男性和女性朋友的屏幕时间相关（p≤0.03），但与他们最好的朋友无关。男性的屏幕时间仅与他们的女性朋友的屏幕时间相关（p=0.04）。女性青少年的身体活动和他们的朋友的身体活动之间的一致关联表明，需要包括青少年女性身体活动的同伴效应在未来的干预工作。
Little is known about the actual physical activity and screen time behaviors of an adolescent’s friends relative to the individual’s behavior. To determine the associations between an adolescent’s physical activity and screen time and his/her nominated friends’ physical activity and screen time. Data were obtained from EAT 2010 (Eating and Activity Among Teens), a large cross-sectional study (n=2126) conducted in 20 middle schools and high schools in Minneapolis/St. Paul MN during the 2009–2010 academic year and analyzed during 2011. Each participant nominated up to six friends from a school roster, and data from those friends were obtained as part of the school-based data collection procedures. Physical activity and screen time were assessed with previously used and validated questionnaires. Generalized estimating equation models, stratified by gender, were used to assess associations between adolescents’ physical activity and screen time and their friends’ physical activity and screen time. Physical activity for female adolescents was associated with their male and female friends’ physical activity, including their male and female best friends (all p<0.05). Males’ physical activity was associated with their female friends’ physical activity (p<0.03). Females’ screen time was associated with their male and female friends’ screen time (p≤0.03), but not with that of their best friends. Males’ screen time was associated with only their female friends’ screen time (p=0.04). The consistent association between female adolescents’ physical activity and their friends’ physical activity indicates a need to include peer effects on adolescent female physical activity in future intervention work.
