Land use mix (LUM) in the neighbourhood is an important aspect for promoting healthier lifestyles and consequently reducing the risk for childhood obesity. However, findings of the association between LUM and childhood obesity remain controversial. A literature search was conducted on Cochrane Library, PubMed and Web of Science for articles published before 1 January 2019. In total, 25 cross-sectional and two longitudinal studies were identified. Among them, Geographic Information Systems were used to measure LUM in 15 studies, and perceived LUM was measured in 12 studies. Generally, most studies revealed an association between a higher LUM and higher PA levels and lower obesity rates, although some studies also reported null or negative associations. The various exposure and outcome assessment have limited the synthesis to obtain pooled estimates. The evidence remains scare on the association between LUM and children's weight status, and more longitudinal studies are needed to examine the independent pathways and causality between LUM and weight-related behaviours/outcomes.
社区土地利用混合（LUM）是促进更健康生活方式的一个重要方面，从而降低儿童肥胖的风险。然而，LUM 与儿童肥胖之间的关联的研究结果仍存在争议。本研究在 Cochrane Library、PubMed 和 Web of Science 上检索了截至 2019 年 1 月 1 日发表的文章。共确定了 25 项横断面研究和 2 项纵向研究。其中，有 15 项研究使用地理信息系统来测量 LUM，12 项研究测量了感知的 LUM。一般来说，大多数研究表明，LUM 较高与较高的 PA 水平和较低的肥胖率之间存在关联，尽管一些研究也报告了无效或负相关的结果。各种暴露和结果评估限制了综合分析以获得汇总估计值。关于 LUM 与儿童体重状况之间的关联的证据仍然很少，需要更多的纵向研究来检验 LUM 与与体重相关的行为/结果之间的独立途径和因果关系。
