健康食品的差异被假设为导致饮食行为和健康结果的差异。虽然在发达的英语国家对食物沙漠进行了广泛的研究，但来自低收入和中等收入国家的证据仍然很少。墨西哥是世界上肥胖症发病率最高的国家之一。随着肥胖症在全国范围内增加并成为一个普遍的公共卫生问题，它正集中在低收入人群中。这项混合方法的研究使用多维方法来分析墨西哥城市低，中，高收入社区的食品环境。该研究通过分析食品出口类型的密度和接近程度以及不同食品的品种，数量，质量，定价和促销，促进了对食品环境在塑造饮食模式中可能发挥的作用的理解。这些措施与对社区家庭的深入定性研究相结合，包括照片启发，以评估对获得食物的看法。这项研究的主要目的是评估不同社会经济地位的社区获得和接触健康和不健康食品的实际和经济机会，以及参与者对这种获得和接触的主观看法。研究结果表明，在分析食品获取时，需要超越对食品商店类型的狭隘关注以及从住宅到杂货店的距离。研究结果表明，过度接触和接触不健康的食物和饮料，或“食物沼泽”，可能是一个更大的关注比食物沙漠的肥胖预防政策在墨西哥。(C)2015爱思唯尔有限公司版权所有。
Differential access to healthy foods has been hypothesized to contribute to disparities in eating behaviors and health outcomes. While food deserts have been researched extensively in developed Anglophone countries, evidence from low- and middle-income countries is still scarce. In Mexico, prevalence of obesity is among the highest worldwide. As obesity has increased nationally and become a widespread public health issue, it is becoming concentrated in the low-income population. This mixed-methods study uses a multidimensional approach to analyze food environments in a low-, middle-, and high-income community in a Mexican city. The study advances understanding of the role that food environments may play in shaping eating patterns by analyzing the density and proximity of food outlet types as well as the variety, quantity, quality, pricing, and promotion of different foods. These measures are combined with in-depth qualitative research with families in the communities, including photo elicitation, to assess perceptions of food access. The central aims of the researchwere to evaluate physical and economic access and exposure to healthy and unhealthy foods in communities of differing socioeconomic status as well as participants' subjective perceptions of such access and exposure. The findings suggest a need to reach beyond a narrow focus on food store types and the distance from residence to grocery stores when analyzing food access. Results show that excessive access and exposure to unhealthy foods and drinks, or "food swamps," may be a greater concern than food deserts for obesity-prevention policy in Mexico.
