We explored the role of dietary factors, as measured by individual behaviors and neighborhood produce availability, in the relationship between food insecurity and obesity among a representative sample of Latinos in California. We utilized data from the 2012, 2013/2014 California Health Interview Survey and included Latinos aged 18-65 years and under 200% of the federal poverty line (n=5,957). We conducted logistic regressions to first estimate the association between food insecurity and obesity and then examine whether this association remained significant after adjusting for soda and fast food consumption, perceived neighborhood fresh produce environment, and covariates. Latina women, and not men, were significantly more likely to be obese if they were very food insecure (OR=1.50, 95% CI=1.03-2.19). After adjusting for diet and neighborhood variables, only neighborhood affordability of fresh produce reduced this significant association. Policy efforts to remediate obesity among food insecurity households should focus on the affordability of neighborhood fresh produce.
我们通过个体行为和社区农产品供应情况来衡量饮食因素，探讨其在加利福尼亚州具有代表性的拉丁裔样本中，粮食不安全与肥胖之间关系中的作用。我们利用了2012年、2013/2014年加利福尼亚健康访谈调查的数据，纳入了年龄在18 - 65岁且收入低于联邦贫困线200%的拉丁裔（n = 5957）。我们进行了逻辑回归分析，首先估计粮食不安全与肥胖之间的关联，然后在调整了汽水和快餐消费、对社区新鲜农产品环境的感知以及协变量后，检验这种关联是否仍然显著。如果拉丁裔女性处于极度粮食不安全状态，她们比男性更易肥胖，差异具有统计学意义（比值比=1.50，95%置信区间=1.03 - 2.19）。在调整饮食和社区变量后，只有社区新鲜农产品的可负担性降低了这种显著关联。改善粮食不安全家庭肥胖状况的政策措施应聚焦于社区新鲜农产品的可负担性。
