肥胖和肥胖相关的合并症在老年人中日益增多。粮食不安全是一个与营养相关的因素，与低收入人群的肥胖共存。大多数关于粮食不安全肥胖悖论的研究都是在低收入母亲和儿童身上进行的，目的本研究的目的是评估低收入老年人中食物不安全与超重和肥胖之间关系的性别差异。研究设计使用2011年和2012年国家健康访谈调查数据。粮食不安全状况由美国农业部粮食安全量表（FSS）的10项中≥ 3项肯定回答确定。身体质量指数（BMI）是根据疾病控制和预防中心根据自我报告的身高和体重计算的。（≥ 60岁），BMI正常（18.5）或更高，具有关于FSS、BMI和以下协变量的完整数据：年龄、种族或民族、婚姻状况、收入、出生状况、身体活动、不良健康状况、健康保险覆盖范围、支付医疗账单或药品的问题以及居住地区（N=5，根据性别对多变量逻辑回归模型进行分层，以估计粮食不安全与较高体重状况之间的关系。结果在协变量调整模型中，与低收入、食物安全的男性相比，低收入、食物不安全的男性超重和超重或肥胖的几率分别低42%和41%。尽管低收入，粮食不安全的妇女，粮食不安全的肥胖患病率高，超重，肥胖，超重或肥胖的老年成年妇女在调整models.Conclusions粮食不安全超重和肥胖的悖论似乎不存在于老年男性。然而，粮食不安全和肥胖症在低收入老年妇女中并存。
Background Obesity and obesity-related comorbidities are increasing among older adults. Food insecurity is a nutrition-related factor that coexists with obesity among low-income individuals. The majority of the research on the food insecurity obesity paradox has been conducted on low-income mothers and children, with research lacking on large diverse samples of older adults.Objective The purpose of this study was to assess gender disparities in the association between food insecurity and overweight and obesity among low-income older adults.Study design Cross-sectional 2011 and 2012 National Health Interview Survey data were used. Food insecurity status was determined by >= 3 affirmative responses on the 10-item US Department of Agriculture Food Security Scale (FSS). Body mass index (BMI) was calculated as outlined by the Centers for Disease Control and Prevention based on self-reported height and weight.Participants/settings Adults included were low-income (= 60 years), with a normal BMI (18.5) or greater who had complete data on FSS, BMI, and the following covariates: age, race or ethnicity, marital status, income, nativity status, physical activity, poor health status, health insurance coverage, problems paying medical bills or for medicine, and region of residency (N=5,506).Statistical analyses performed Multivariate logistic regression models were stratified by gender to estimate the association between food insecurity and higher weight status. All models included covariates.Results In covariate-adjusted models, compared with low-income, food secure men, low-income, food-insecure men had 42% and 41% lower odds of being overweight and overweight or obese, respectively. Despite the high prevalence rate of obesity among low-income, food-insecure women, food insecurity was not significantly related to overweight, obesity, or overweight or obesity for older adult women in adjusted models.Conclusions Food insecurity overweight and obesity paradox appears not to be present in older men. However, food insecurity and obesity coexist among low-income, older women.
