有证据表明，食物出口的获得根据邻里剥夺的程度而有所不同，但人们对个人情况如何影响食物出口和饮食之间的关联知之甚少。这项研究探讨了饮食质量和整体食品环境之间的关系，代表了个性化活动空间中健康和不健康食品出口之间的平衡。此外，这项研究是第一次评估影响修改的教育程度对这种关系。来自英国汉普郡的839名母亲完成了一项横断面调查，包括20项食物频率问卷，以衡量饮食和人口统计学特征以及经常访问的地点，包括家庭，儿童中心，全科医生，工作，主要食品店和体育活动地点。饮食信息用于计算每个母亲的标准化饮食质量评分。个性化的活动空间是通过使用ArcGIS在经常访问的地点周围创建1000米的缓冲区来产生的。横断面观察的食物出口数据覆盖到活动空间，以获得每个母亲的整体食物环境评分。这些分数代表了健康和不健康食品商店之间的平衡，使用权重来衡量每种商店类型中销售的健康或不健康食品的比例。食品店主要是不健康的食品店;只有1%的母亲在日常活动中接触到健康的整体食品环境。受教育程度调节了整体食物环境和饮食之间的关系（中vs低，p = 0.06;高vs低，p = 0.04）。调整后的分层线性回归分析显示，在有学位的母亲中，较差的食物环境与较好的饮食质量相关（β = -0.02，95%CI：-0.03，-0.001）和低文化程度母亲的饮食质量差的倾向，但这种关系没有统计学意义（β = 0.01; 95%CI：-0.01，0.02）。这项研究表明，不健康的食品店，如外卖和便利店，占主导地位的母亲的食品店的访问，并提供了一些经验证据支持的概念，个人特征，特别是教育程度，是保护接触不健康的食品环境。通过规划限制改善健康和不健康食品销售点的不平衡，对于减少饮食不平等可能很重要。
There is evidence that food outlet access differs according to level of neighbourhood deprivation but little is known about how individual circumstances affect associations between food outlet access and diet. This study explored the relationship between dietary quality and a measure of overall food environment, representing the balance between healthy and unhealthy food outlet access in individualised activity spaces. Furthermore, this study is the first to assess effect modification of level of educational attainment on this relationship. A total of 839 mothers with young children from Hampshire, United Kingdom (UK) completed a cross-sectional survey including a 20-item food frequency questionnaire to measure diet and questions about demographic characteristics and frequently visited locations including home, children’s centre, general practitioner, work, main food shop and physical activity location. Dietary information was used to calculate a standardised dietary quality score for each mother. Individualised activity spaces were produced by creating a 1000m buffer around frequently visited locations using ArcGIS. Cross-sectional observational food outlet data were overlaid onto activity spaces to derive an overall food environment score for each mother. These scores represented the balance between healthy and unhealthy food outlets using weightings to characterise the proportion of healthy or unhealthy foods sold in each outlet type. Food outlet access was dominated by the presence of unhealthy food outlets; only 1% of mothers were exposed to a healthy overall food environment in their daily activities. Level of educational attainment moderated the relationship between overall food environment and diet (mid vs low, p = 0.06; high vs low, p = 0.04). Adjusted stratified linear regression analyses showed poorer food environments were associated with better dietary quality among mothers with degrees (β = -0.02; 95%CI: -0.03, -0.001) and a tendency toward poorer dietary quality among mothers with low educational attainment, however this relationship was not statistically significant (β = 0.01; 95%CI: -0.01, 0.02). This study showed that unhealthy food outlets, like takeaways and convenience stores, dominated mothers’ food outlet access, and provides some empirical evidence to support the concept that individual characteristics, particularly educational attainment, are protective against exposure to unhealthy food environments. Improvements to the imbalance of healthy and unhealthy food outlets through planning restrictions could be important to reduce dietary inequalities.
