Objective To systematically evaluate the relationship between the community food environment with overweight and obesity risk in children, and to provide evidence-based evidence for the development of guidelines and policies.
Methods Relevant Chinese and English literatures published from 1998 to 2020 were searched in the database of CBM, CNKI, Wanfang Data, Cochrane Library, PubMed, EMbase.
Results A total of 8 English literatures were included in this systematic evaluation, including 3 cohort studies and 5 cross-sectional studies. The results showed that the number and type, as well as distance to food stores/restaurants in the neighborhood of family or school were associated with the weight status, waist circumference and obesity risk of children. The number of fast food restaurants, convenience stores, and grocery stores was positively correlated with the risk of childhood obesity, and the number of supermarkets and free markets was associated with a lower risk of overweight and obesity in children.
Conclusion The community food environment might be associated with childhood obesity, which is warrented more high-quality scientific evidence.
【摘要】 目的 系统评价社区食物环境与儿童超重肥胖的关系, 为相关政策的制定提供循证证据。 方法 检索 1998— 2020 年公开发表的相关文献, 中文数据库为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, 英文数据库为 Cochrane library、PubMed、EMbase 等。 结果 经过文献筛选, 共有 8 篇英文文献纳人本次系统评价, 包括 3 项队列研究和 5 项横断面研究。结果显示, 家庭或学校周边社区的食品商店/餐厅类型、数量、距离、食物价格等与儿童体 重、腰围及肥胖风险有关。其中快餐店、便利店、杂货店的数量与儿童肥胖髙风险有关, 超市、自由市场的数量与儿童肥胖 低风险有关。 结论 社区食物环境与儿童肥胖可能有关, 还需要更多髙质量研究设计的证据支持。
