目的：利用2007-2008年全国健康营养调查（NHANES）的数据，本研究进行了性别分析，以研究粮食不安全对个体体重指数（BMI）的影响。最近的文献已经确定了食物不安全-肥胖悖论的存在，即食物不安全的人更有可能拥有更高的体重指数，这种关联在女性中尤其普遍。人们提出了各种可能解释这一悖论的机制。设计横断面：评估粮食不安全与妇女之间的关系。采用多元回归技术对潜在的中介危险因素进行检验。背景：2007-2008年美国全国健康与营养调查研究对象：24-64岁的女性结果：食品不安全与女性较高的身体质量指数有关。潜在的机制，如健康食品的可获得性、去杂货店的时间、压力和健康保险获得与BMI有独立的关联，但没有介导食品不安全和BMI之间的关系。结论：结果证实了食品不安全与女性BMI升高之间的正相关。然而，这些分析并没有为研究文献中描述的机制的中介作用提供证据。未来的研究应该努力识别和测试其他可能的影响途径，以解释这种食物不安全-肥胖悖论。
Objective: Using data from the 2007-2008 continuous National Health Nutrition Examination Survey NHANES, this study conducted gender-specific analyses to examine the influence of food insecurity on individual Body Mass Index (BMI). The recent literature has identified the existence of the food insecurity-obesity paradox such that individuals who are food insecure are more likely to have higher BMI, and this association is especially prevalent among women. Various mechanisms have been proposed as having the potential for explaining this paradox.Design Cross-sectional: The relationship between food insecurity and women was assessed. Potential mediating risk factors were tested using multiple regression techniques.Setting: The 2007-2008 National Health and Nutrition Examination Survey, USASubjects: Women 24-64 years of ageResults: Food insecurity is associated with greater body mass index among women. Potential mechanisms such as availability of health foods, time to grocery store, stress, and health insurance access had independent associations with BMI but did not mediate the relationship between food insecurity and BMI.Conclusion: Results confirm the positive association between food insecurity and elevated BMI among women. However, these analyses do not provide evidence for a mediating role of mechanisms described in the research literature. Future research should strive to identify and test for other potential pathways of influence that might explain this food insecurity-obesity paradox.
