Prior research shows that food insecurity is associated with being overweight in women, with few and ambiguous results in men. Little is known about the characteristics and roles of individuals who are most likely to be both food insecure and overweight or obese. This study analyzed associations between food insecurity and body weight, and whether gender and marital status are involved in that relationship. Using multiple regression models, we examined food insecurity, marriage, and body weight among 4338 men and 4172 women aged > or = 20 y in the 1999-2002 NHANES. Married men were more likely to be overweight than men in all other marital-status categories except for those living with partners. Divorced men were more likely than never-married men to live in a household with very low food security. Compared with fully food-secure men, marginally food-secure men were heavier, whereas men with low food security were lighter. Compared with fully food-secure women, marginally food-secure women also showed a tendency to be overweight (P = 0.05), whereas women with low food security were more likely to be obese. When considering the interaction between food insecurity and marital status, food insecurity was related to a greater likelihood of obesity among married women, those living with partners, and widows, when compared with never-married women. Sensitivity analyses suggest this effect was concentrated among marginally food-secure women. These findings indicate that food insecurity relates differently to body weight for men and women, and that partnering plays a strong part in this relationship for women.
先前的研究表明，粮食不安全与女性超重有关，而在男性中结果很少且不明确。对于最有可能既粮食不安全又超重或肥胖的个体的特征和作用知之甚少。本研究分析了粮食不安全与体重之间的关联，以及性别和婚姻状况是否参与了这种关系。我们使用多元回归模型，研究了1999 - 2002年美国国家健康与营养检查调查（NHANES）中4338名年龄≥20岁的男性和4172名女性的粮食不安全、婚姻状况和体重情况。已婚男性比除与伴侣同居者外的所有其他婚姻状况类别的男性更有可能超重。离婚男性比从未结婚的男性更有可能生活在粮食安全水平极低的家庭中。与粮食完全安全的男性相比，粮食安全边际的男性体重更重，而粮食安全低的男性体重更轻。与粮食完全安全的女性相比，粮食安全边际的女性也有超重的倾向（P = 0.05），而粮食安全低的女性更有可能肥胖。在考虑粮食不安全与婚姻状况之间的相互作用时，与从未结婚的女性相比，粮食不安全与已婚女性、与伴侣同居的女性和寡妇中肥胖的可能性更大有关。敏感性分析表明，这种影响集中在粮食安全边际的女性中。这些发现表明，粮食不安全与男性和女性体重的关系不同，并且伴侣关系在女性的这种关系中起着重要作用。
