背景：粮食不安全是一种低或极低粮食安全状况，与营养摄入减少和健康状况不佳有关，这可能导致儿童营养缺乏，包括缺铁和缺铁性贫血。目的：本研究的目的是正式调查 3-19 岁儿童（n = 11,247）当前铁状况和粮食安全状况的关系。设计：1999-2004 年国家健康和营养检查调查的参与者按粮食安全分类通过使用美国儿童食品安全量表和美国家庭食品安全量表来评估状况。缺铁定义为转铁蛋白饱和度、血清铁蛋白和红细胞原卟啉> 2个异常值，加上血红蛋白异常来分类缺铁性贫血。结果：12-15岁儿童缺铁性贫血的几率是食品不安全家庭儿童的2.95倍（95% CI：1.18，7.37；P = 0.02）。结论：这项研究的结果表明，仍然需要成功的干预措施，以减少粮食不安全儿童的缺铁性贫血，并改善儿童的粮食安全。美国临床营养杂志 2009； 90：1358-71。
Background: Food insecurity, a condition of low or very low food security, is associated with decreased nutrient intake and poor health, which can lead to nutrient deficiency in children, including iron deficiency and iron deficiency anemia.Objective: The purpose of this study was to formally investigate the current relation of iron status and food security status among children aged 3-19 y (n = 11,247).Design: Participants of the National Health and Nutrition Examination Survey 1999-2004 were classified for food security status by using the US Children's Food Security Scale and the US Household Food Security Scale. Iron deficiency was defined as > 2 abnormal values for transferrin saturation, serum ferritin, and erythrocyte protoporphyrin, with the addition of abnormal hemoglobin to classify iron deficiency anemia.Results: The odds of iron deficiency anemia among children aged 12-15 y were 2.95 times (95% CI: 1.18, 7.37; P = 0.02) those for children in households with food insecurity among children compared with children in households with food security among children.Conclusions: The results of this study indicate a continuing need for successful interventions to reduce iron deficiency anemia among food-insecure children and to improve food security among children.
