目的：测试感知环境因素的贡献方法：来自45个社区的1580名妇女的社区样本提供了关于她们的社会经济地位（SEP）的调查数据。（教育和收入）;饮食（水果、蔬菜和快餐消费量）;以及当地健康食品的可获得性、可获得性和成本。一旦考虑到感知的环境变量，SEP和饮食之间的关联是弱的和不显着的，这表明饮食的社会经济差异几乎完全可以通过对食物可用性，可获得性和可负担性的看法来解释。减少饮食中社会经济不平等的战略可能涉及促进廉价的方式来增加水果和蔬菜的消费，并确保低SEP的人意识到许多健康食品可以以相对较低的成本获得。未来的研究还应确认人们的看法是否与粮食供应、可获得性和可负担性的客观衡量标准相匹配，以解决低SEP社区中真实的和/或认为缺乏健康选择的问题。
Objectives: To test the contribution of perceived environmental factors (food availability, accessibility and affordability) to mediating socioeconomic variations in women's fruit, vegetable and fast food consumption.Methods: A community sample of 1580 women from 45 neighbourhoods provided survey data on their socioeconomic position (SEP) (education and income); diet (fruit, vegetable and fast food consumption); and the perceived availability of, access to and cost of healthy food in their local area.Results: Once perceived environmental variables were considered, the associations between SEP and diet were weak and non-significant, suggesting that socioeconomic differences in diet were almost wholly explained by perceptions of food availability, accessibility and affordability.Conclusions: Strategies to decrease socioeconomic inequalities in diet could involve promoting inexpensive ways to increase fruit and vegetable consumption, and ensuring that people of low SEP are aware that many healthy foods are available at relatively low cost. Future research should also confirm if perceptions match objective measures of food availability, accessibility and affordability, in order to address the real and/or perceived lack of healthy options in low SEP neighbourhoods.
