由于食物选择的改变和不统一的消费模式，粮食不安全可能使儿童面临更大的肥胖风险。目的研究美国儿童肥胖与儿童水平食品不安全和个人食品不安全之间的关系。设计分析了2001-2010年全国健康与营养调查中9701名2 - 11岁参与者的数据。儿童水平的粮食不安全是通过美国农业部的粮食安全调查模块评估的，该模块基于八个针对儿童的问题。个人粮食不安全状况通过五个附加问题进行评估。肥胖被定义为身体质量指数（以kg/m(2)计算）大于或等于疾病控制和预防中心生长图表中年龄和性别特异性的第95个百分位数。对性别、种族/民族、贫困水平和调查年份进行了调整后的Logistic回归，以描述肥胖与食品不安全之间的关系。结果肥胖与6 - 11岁儿童的个人食品不安全显著相关（优势比= 1.81;95% CI 1.33 - 2.48），但与2 - 5岁儿童无关（优势比= 0.88;95% CI 0.51 - 1.51）。儿童水平的食物不安全与2至5岁或6至11岁儿童的肥胖无关。结论：个人粮食不安全仅与6 - 11岁儿童肥胖风险增加有关。个人粮食不安全措施可能产生与儿童总体粮食不安全措施不同的结果。
Background Food insecurity can put children at greater risk of obesity because of altered food choices and nonuniform consumption patterns.Objective We examined the association between obesity and both child-level food insecurity and personal food insecurity in US children.Design Data from 9,701 participants in the National Health and Nutrition Examination Survey, 2001-2010, aged 2 to 11 years were analyzed. Child-level food insecurity was assessed with the US Department of Agriculture's Food Security Survey Module based on eight child-specific questions. Personal food insecurity was assessed with five additional questions. Obesity was defined, using physical measurements, as body mass index (calculated as kg/m(2)) greater than or equal to the age-and sex-specific 95th percentile of the Centers for Disease Control and Prevention growth charts. Logistic regressions adjusted for sex, race/ethnic group, poverty level, and survey year were conducted to describe associations between obesity and food insecurity.Results Obesity was significantly associated with personal food insecurity for children aged 6 to 11 years (odds ratio = 1.81; 95% CI 1.33 to 2.48), but not in children aged 2 to 5 years (odds ratio = 0.88; 95% CI 0.51 to 1.51). Child-level food insecurity was not associated with obesity among 2-to 5-year-olds or 6-to 11-year-olds.Conclusions Personal food insecurity is associated with an increased risk of obesity only in children aged 6 to 11 years. Personal food-insecurity measures may give different results than aggregate food-insecurity measures in children.
