Abstract: Objective To systematically evaluate the relation between eating out of/at home and overweight risk in children, in order to provide evidence-based reference for the development of guidelines and policies. Methods Related literature published in Cochrane library, PubMed, EMBASE, China Biomedical Literature Database (CBM), China National Knowledge Network (CNKI) and Wanfang Data Knowledge Service platform from January 1st, 1998 to December 31st, 2021 was systematically searched. Data were extracted and included articles were evaluated according to GRADE standards. Results A total of 10 cross-sectional studies and 3 cohort studies were included. The results showed that children tended to choose healthy food when eating at home. However, eating out, especially for western fast food, was associated with high fat, high sugar and high energy food intake. Frequently eating out increased the risk of overweight and obesity in children, which was related to children′s age, gender and weight status. Conclusions Eating out of/at home might be related to childhood obesity, which needs to be supported by more evidence from high-quality researches. In order to prevent and control childhood obesity, it is recommended that children eat at home more often.

摘要： 目的 系统评价就餐地点与儿童能量摄入及肥胖的关系,为相关政策的制定提供循证依据。方法 系统检索Cochrane library, PubMed, EMBASE和中国生物医学文献数据库(CBM)、中国知网(CNKI)、万方数据知识服务平台中,1998年1月1日—2021年12月31日发表的相关文献,提取资料并依据GRADE标准评价纳入文献。结果 共纳入10项横断面研究和3项队列研究。结果显示,儿童在家就餐倾向于选择健康食物,在外就餐尤其西式快餐与高脂肪高糖高能量食物摄入有关;经常在外就餐可增加儿童超重肥胖风险,与儿童年龄、性别、体质量状况等有关。结论 就餐地点与儿童肥胖可能有关,需更多高质量研究设计的证据支持。为预防与控制儿童肥胖,建议儿童多在家就餐。
