PURPOSE
The aim of the present study was to analyze the associations of youths' sedentary behavior (SB) with parents' and siblings' SB and physical activity (PA), as well as the associations of youths' coparticipation with parents, siblings, and friends in PA and SB with youths' SB.
METHODS
The sample consisted of 1543 youths (12.02 ± 2.51 years; 788 boys) enrolled in the baseline cohort of the UP&DOWN study. SB was assessed by accelerometry and questionnaire. Participants reported the time spent by their parents and siblings watching television, playing videogames, surfing the Internet, sitting/resting, and doing PA. Further, participants reported coparticipation with parents, siblings, and friends in these activities. Linear mixed models, including school and city as random effects, were performed.
RESULTS
Parents' television time was positively associated with youths' screen-based SB. Coparticipation with friends in playing videogames (in boys) and in surfing the Internet (in girls) showed a positive association with screen-based SB and a negative association with educational-based SB. Moreover, coparticipation with siblings and friends in PA was inversely associated with accelerometer-based SB in boys and girls.
CONCLUSION
Our results emphasize the important role of social modeling in the development of sedentary lifestyles in youths. Interventions aimed at reducing health risk behaviors in youths could be more effective if they are oriented from a social perspective that involves their families and networks of their closest friends.
目的
本研究旨在分析青少年久坐行为（SB）与父母和兄弟姐妹的 SB 和身体活动（PA）之间的关联，以及青少年与父母、兄弟姐妹和朋友共同参与 PA 和 SB 与青少年 SB 之间的关联。
方法
该样本由参加 UP&DOWN 研究基线队列的 1543 名青少年（12.02 ± 2.51 岁；788 名男孩）组成。通过加速度计和问卷调查评估 SB。参与者报告了父母和兄弟姐妹看电视、玩电子游戏、上网、坐着/休息和进行 PA 的时间。此外，参与者还报告了与父母、兄弟姐妹和朋友共同参与这些活动的情况。采用线性混合模型，包括学校和城市作为随机效应进行分析。
结果
父母看电视的时间与青少年基于屏幕的 SB 呈正相关。与朋友一起玩电子游戏（男孩）和上网（女孩）与基于屏幕的 SB 呈正相关，与基于教育的 SB 呈负相关。此外，兄弟姐妹和朋友之间的 PA 共同参与与男孩和女孩的基于加速度计的 SB 呈负相关。
结论
我们的研究结果强调了社会榜样在青少年久坐生活方式发展中的重要作用。如果从涉及他们的家庭和最亲密朋友网络的社会角度出发，针对青少年减少健康风险行为的干预措施可能会更加有效。
