Grocery store is usually considered to be a healthy food outlet as it provides access to a variety of healthy food, such as fruits and vegetables, which may potentially improve overall dietary quality and protect against obesity. However, findings of the association between grocery store and childhood obesity are controversial. This study aimed to systematically review the evidence on the association between access to grocery stores and childhood obesity. A literature search was conducted in the PubMed, Embase, and Web of Science for articles published before January 1, 2019, using the combinations of three groups of keywords separately for grocery store, children and adolescents, and weight-related behaviours and outcomes. A total of 27 cross-sectional and eight longitudinal studies were identified. Controversial results existed among 24 studies, which examined the association between the access to grocery stores and weight-related outcomes. A null association was observed in almost all meta-analyses conducted by different measures of grocery stores and weight status, except the analysis between presence of grocery stores and overweight, which reached borderline significance. For weight-related behaviours, mixed findings were reported between grocery stores and dietary behaviours, and no significant associations were found for physical activity. This systematic review and meta-analysis suggested that access to grocery stores may have a rather small influence on child weight.
杂货店通常被认为是健康食品的销售点，因为它提供了各种健康食品，如水果和蔬菜，这可能会提高整体饮食质量并预防肥胖。然而，杂货店与儿童肥胖之间的关联的研究结果存在争议。本研究旨在系统地回顾有关杂货店与儿童肥胖之间关联的证据。在 PubMed、Embase 和 Web of Science 中，使用三组关键词的组合对截至 2019 年 1 月 1 日之前发表的文章进行了检索，三组关键词分别为杂货店、儿童和青少年以及与体重相关的行为和结果。共确定了 27 项横断面研究和 8 项纵向研究。24 项研究检查了杂货店的可达性与体重相关结果之间的关联，结果存在争议。除了杂货店的存在与超重之间的分析达到边缘显著外，几乎所有使用不同杂货店衡量指标进行的荟萃分析都观察到了与体重状况之间的无关联。对于与体重相关的行为，杂货店与饮食行为之间的报告结果存在差异，而与身体活动之间没有发现显著关联。本系统评价和荟萃分析表明，杂货店的可达性可能对儿童体重的影响较小。
