Physical activity (PA) is beneficial for child health; however, few children meet PA guidelines. Social relationships impact child PA behaviors; however, little is known about this effect in Mexican-heritage populations. This study aims to understand associations between self-reported play networks and PA among Mexican-heritage children. Mexican-heritage children from colonias along the Texas-Mexico border (n = 44; 54.5% girls; mean age = 9.89 years, SD = 0.97) reported information on up to 5 people they played with most often. Linear regression was used to analyze the relationship between composition of children's social network and minutes of moderate- to vigorous-intensity PA (MVPA) and sedentary minutes per day measured by accelerometers. Children who reported a higher percentage of friends as opposed to family members attained significantly more minutes of MVPA per day (β = .27, P = .04). Children who reported playing with individuals in their network more often (β = ‒.28, P = .03) were sedentary for fewer minutes per day. Increasing the connections between children in the neighborhood or community, as well as increasing a child's frequency of active play, may be promising approaches to increasing MVPA and decreasing sedentary behaviors among Mexican-heritage children.
身体活动（PA）对儿童健康有益；然而，很少有儿童达到PA指南的要求。社会关系会影响儿童的PA行为；然而，对于墨西哥裔人群中的这种影响却知之甚少。本研究旨在了解墨西哥裔儿童自我报告的玩耍网络与PA之间的关联。来自德克萨斯州与墨西哥边境聚居区的墨西哥裔儿童（n = 44；54.5%为女孩；平均年龄 = 9.89岁，标准差 = 0.97）报告了最多5名他们最常一起玩耍的人的信息。使用线性回归分析儿童社交网络的组成与通过加速度计测量的中度至剧烈强度PA（MVPA）分钟数以及每天久坐分钟数之间的关系。报告中朋友占比高于家庭成员的儿童每天获得的MVPA分钟数显著更多（β = 0.27，P = 0.04）。报告更频繁与社交网络中的人一起玩耍的儿童（β = -0.28，P = 0.03）每天久坐的分钟数更少。增加邻里或社区中儿童之间的联系，以及增加儿童积极玩耍的频率，可能是增加墨西哥裔儿童MVPA并减少久坐行为的有前景的方法。
