出版信息
J Phys Act Health. 2020 Feb 1;17(2):250-260. doi: 10.1123/jpah.2019-0350.
BACKGROUND
Regular physical activity (PA) has many benefits for children and adolescents, yet many do not meet PA recommendations. Social context is important for promoting or discouraging PA among children and adolescents. This review aimed to identify social network variables related to PA among children and adolescents.
METHODS
A systematic review of the literature was conducted in September 2018 using PsycINFO, MEDLINE, PubMed, and Web of Science. Included articles needed to (1) be focused on children (aged 5-11 y) or adolescents (aged 12-17 y), (2) include a measure of PA, (3) include a measure of egocentric or sociocentric social connection in which alters were nominated, and (4) perform an analysis between network data and PA.
RESULTS
A search of 11,824 articles was refined to a final sample of 29 articles. Social network themes and concepts such as homophily, centrality, and network composition were related to child and adolescent PA behavior across the literature.
CONCLUSIONS
The impact of an individual's social network is evident on their PA behaviors. More research is needed to examine why these networks form in relation to PA and how interventions can utilize social network analysis to more effectively promote PA, especially in underserved and minority populations.
背景
有规律的身体活动（PA）对儿童和青少年有很多好处，但许多人达不到 PA 推荐量。社会环境对促进或阻碍儿童和青少年的 PA 很重要。本综述旨在确定与儿童和青少年 PA 相关的社会网络变量。
方法
2018 年 9 月，使用 PsycINFO、MEDLINE、PubMed 和 Web of Science 进行了系统的文献综述。纳入的文章需要：（1）针对儿童（5-11 岁）或青少年（12-17 岁）；（2）包含 PA 测量；（3）包含自我中心或社会中心的社交联系测量，其中改变了被提名；（4）在网络数据和 PA 之间进行分析。
结果
对 11824 篇文章进行搜索，最终筛选出 29 篇文章作为最终样本。整个文献中，社会网络主题和概念，如同质性、中心性和网络构成，与儿童和青少年的 PA 行为有关。
结论
个人的社会网络对其 PA 行为有明显影响。需要进一步研究为什么这些网络与 PA 形成，以及干预措施如何利用社会网络分析来更有效地促进 PA，特别是在服务不足和少数族裔人群中。
