Abstract

Methods: Four schools were randomly allocated to one of four conditions: a social network intervention using influence agents focusing on water consumption, physical activity, a combination of the two, or a passive control condition. Participants included a total of 201 6- to-11-year-old children (53.7% girls; M_age = 8.51, SD_age = 0.93). At baseline, 149 (76.0%) participants had a healthy weight, 29 (14.8%) had overweight and 18 (9.2%) had obesity.

Results: Linear mixed effect models indicated that a multi-component school-based social network intervention targeting both water consumption and physical activity was most effective in decreasing children's zBMI.

Conclusion: This study suggests that schools can contribute to the intervention of childhood obesity-even without involving the parents-by targeting both children's water consumption and physical activity through influential peers, but more research is needed to identify mechanisms of change.

多成分校本社交网络干预对儿童体重指数的影响：一项四臂干预研究。

目的学校被认为是促进健康体重的重要环境。目前的研究是一项独特的研究，它考察了基于学校的多成分社交网络干预对儿童体重指数 z 值（zBMI）的影响：四所学校被随机分配到四种条件中的一种：使用影响力代理的社交网络干预，重点关注水的消耗、体育锻炼、两者的结合或被动对照条件。参与者包括 201 名 6-11 岁的儿童（53.7% 为女孩；平均年龄为 8.51 岁，平均年龄为 0.93 岁）。基线时，149 名（76.0%）参与者体重健康，29 名（14.8%）超重，18 名（9.2%）肥胖：线性混合效应模型表明，针对饮水量和体育锻炼的多成分学校社会网络干预措施对降低儿童的 zBMI 最有效：这项研究表明，即使没有家长的参与，学校也可以通过有影响力的同伴针对儿童的饮水量和体育锻炼进行干预，从而为干预儿童肥胖做出贡献，但还需要更多的研究来确定改变的机制。
