To investigate the potential dietary impact of the opening of new retailers of healthy foods.
Systematic review of the peer-reviewed research literature.
References published before November 2015 were retrieved from MEDLINE, EMBASE and Web of Science databases using keyword searches.
The outcome of the review was change in fruit and vegetable consumption among adults.
Of 3514 references retrieved, ninety-two articles were reviewed in full text, and twenty-three articles representing fifteen studies were included. Studies used post-test only (n 4), repeated cross-sectional (n 4) and repeated measures designs (n 7) to evaluate the dietary impact of supermarket (n 7), farmers' market (n 4), produce stand (n 2) or mobile market (n 2) openings. Evidence of increased fruit and vegetable consumption was most consistent among adults who began shopping at the new retailer. Three of four repeated measures studies found modest, albeit not always statistically significant, increases in fruit and vegetable consumption (range 0·23-0·54 servings/d) at 6-12 months after baseline. Dietary change among residents of the broader community where the new retailer opened was less consistent.
The methodological quality of studies, including research designs, sampling methods, follow-up intervals and outcome measures, ranged widely. Future research should align methodologically with previous work to facilitate meta-analytic synthesis of results. Opening a new retailer may result in modest short-term increases in fruit and vegetable consumption among adults who choose to shop there, but the potential longer-term dietary impact on customers and its impact on the broader community remain unclear.
研究新的健康食品零售商开业对饮食的潜在影响。
对同行评审的研究文献进行系统回顾。
使用关键词搜索，从 MEDLINE、EMBASE 和 Web of Science 数据库中检索 2015 年 11 月之前发表的参考文献。
本次综述的结果为成年人水果和蔬菜摄入量的变化。
在检索到的 3514 篇参考文献中，有 92 篇文章进行了全文审查，23 篇文章（代表 15 项研究）被纳入。研究使用后测仅（n 4）、重复横断面（n 4）和重复测量设计（n 7）来评估超市（n 7）、农贸市场（n 4）、农产品摊位（n 2）或流动市场（n 2）开业对饮食的影响。在开始在新零售商购物的成年人中，水果和蔬菜摄入量增加的证据最为一致。四项重复测量研究中有三项发现，水果和蔬菜摄入量适度增加（范围 0.23-0.54 份/天），基线后 6-12 个月（n 4）。新零售商所在社区的居民的饮食变化则不太一致。
研究的方法质量，包括研究设计、抽样方法、随访间隔和结果测量，差异很大。未来的研究应在方法上与以前的工作保持一致，以便对结果进行荟萃分析。新零售商的开业可能会导致选择在那里购物的成年人短期内水果和蔬菜摄入量适度增加，但长期来看对顾客的潜在饮食影响及其对更广泛社区的影响仍不清楚。
