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.

杂货店准入和儿童肥胖：系统评价和荟萃分析。

杂货店通常被认为是一个健康食品出口，因为它提供了各种健康食品，例如水果和蔬菜，这可能会改善整体饮食质量并防止肥胖。然而，杂货店与儿童肥胖之间关联的发现是有争议的。本研究旨在系统地审查有关进入杂货店与儿童肥胖之间关联的证据。在 PubMed、Embase 和 Web of Science 中对 2019 年 1 月 1 日之前发表的文章进行了文献检索，分别使用三组关键词组合杂货店、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 项研究中存在有争议的结果，它检查了进入杂货店的机会与体重相关结果之间的关联。除了杂货店的存在与超重之间的分析达到临界显着性之外，在几乎所有通过杂货店和体重状态的不同测量进行的荟萃分析中都观察到了零关联。对于与体重相关的行为，杂货店和饮食行为之间报告的结果不一，没有发现与身体活动有显着关联。这项系统评价和荟萃分析表明，进入杂货店对儿童体重的影响可能相当小。除了杂货店的存在与超重之间的分析达到临界显着性之外，在几乎所有通过杂货店和体重状态的不同测量进行的荟萃分析中都观察到了零关联。对于与体重相关的行为，杂货店和饮食行为之间报告的结果不一，没有发现与身体活动有显着关联。这项系统评价和荟萃分析表明，进入杂货店对儿童体重的影响可能相当小。除了杂货店的存在与超重之间的分析达到临界显着性之外，在几乎所有通过杂货店和体重状态的不同测量进行的荟萃分析中都观察到了零关联。对于与体重相关的行为，杂货店和饮食行为之间报告的结果不一，没有发现与身体活动有显着关联。这项系统评价和荟萃分析表明，进入杂货店对儿童体重的影响可能相当小。
