High accessibility of unhealthy food stores may contribute to a poor dietary quality. Research on the link between neighbourhood food environment and consumption is limited, especially in a European context. The objective of this study was to examine the relationship between convenience stores (CS) and dietary quality within the Capital Region of Denmark.
Cross-sectional study of the geographic food environment in the Capital Region of Denmark based on 47 623 subjects (age 16+ years) with complete information on retail food environment and dietary quality. A categorization procedure to identify CS from a government list of inspected food stores (the Smiley register) was developed. Using GIS network analyses, density of CS within 0.25 km and 0.5 km network buffers from residency was calculated for participants in metropolitan and non-metropolitan areas, respectively. Information on dietary intake and confounders is derived from a questionnaire survey. Multi-level analyses were performed, adjusting for age, sex, individual socio-economic factors and area socio-economic status.
In the non-metropolitan population, the odds of having an unhealthy diet increased significantly (P < 0.0001) with increased density of CS. Compared to individuals who did not have a CS within 0.5 km from their home, the odds ratios were 1.20 (95% CI: 1.09-1.33) and 1.37 (95% CI: 1.19-1.57) for individuals having 1 or ≥2 CS, respectively. In the fully adjusted model, the overall association remained significant (P = 0.015) and odds ratios diminished to 1.14 (1.02-1.27) and 1.18 (1.01-1.38).
High accessibility of CS in neighbourhoods is associated with less healthy dietary habits among residents.
不健康食品商店的高可达性可能导致饮食质量较差。关于邻里食物环境与消费之间联系的研究有限，尤其是在欧洲背景下。本研究的目的是调查丹麦首都地区便利店（CS）与饮食质量之间的关系。
基于47623名年龄在16岁及以上的受试者，对丹麦首都地区的地理食物环境进行横断面研究，这些受试者拥有关于零售食物环境和饮食质量的完整信息。开发了一种从政府检查食品商店列表（笑脸登记册）中识别CS的分类程序。使用地理信息系统网络分析，分别计算大都市和非大都市地区参与者居住地点0.25公里和0.5公里网络缓冲区内CS的密度。饮食摄入和混杂因素的信息来自问卷调查。进行了多水平分析，并对年龄、性别、个人社会经济因素和地区社会经济状况进行了调整。
在非大都市人群中，不健康饮食的几率随着CS密度的增加而显著增加（P<0.0001）。与家周围0.5公里内没有CS的个体相比，有1家或≥2家CS的个体的优势比分别为1.20（95%可信区间：1.09 - 1.33）和1.37（95%可信区间：1.19 - 1.57）。在完全调整模型中，总体关联仍然显著（P = 0.015），优势比降至1.14（1.02 - 1.27）和1.18（
