在美国，大约有1020万人有时或经常没有足够的食物吃，这种情况被称为食物不足。使用第三次全国健康和营养检查调查(NHANES III)的横断面数据，我们检验了来自食物不足家庭(FIF)的成年人和来自食物充足家庭(FSF)的成年人之间的膳食摄入量和血清营养素是否存在差异。根据年龄组分层并根据家庭收入和其他重要协变量进行调整的分析结果显示了几个重要的发现(P<；0.05)。与食物充足的同龄人相比，来自FIF的年轻人(20-59岁)的钙摄入量较低，并且在给定的一天中，钙和维生素E的摄入量更有可能低于推荐量的50%。来自FIF的年轻人也报告了较低的1个月牛奶/奶制品、水果/果汁和蔬菜的消费频率。此外，来自FIF的年轻人的血清总胆固醇、维生素A和三种胡萝卜素(-胡萝卜素、β-隐黄质和叶黄素/玉米黄质)浓度较低。来自FIF的老年人(年龄大于或等于60岁)能量、维生素B-6、镁、铁和锌的摄入量较低，并且更有可能在给定的一天中铁和锌的摄入量低于推荐量的50%。FIF的老年人血清高密度脂蛋白胆固醇、白蛋白、维生素A、β-隐黄素和维生素E的浓度也较低。
Approximately 10.2 million persons in the United States sometimes or often do not have enough food to eat, a condition known as food insufficiency. Using cross-sectional data from the Third National Health and Nutrition Examination Survey (NHANES III), we examined whether dietary intakes and serum nutrients differed between adults from food-insufficient families (FIF) and adults from food-sufficient families (FSF). Results from analyses, stratified by age group and adjusted for family income and other important covariates, revealed several significant findings (P < 0.05). Compared with their food-sufficient counterparts, younger adults (aged 20-59 y) from FIF had lower intakes of calcium and were more likely to have calcium and vitamin E intakes below 50% of the recommended amounts on a given day. Younger adults from FIF also reported lower 1-mo frequency of consumption of milk/milk products, fruits/fruit juices and vegetables. In addition, younger adults from FIF had lower serum concentrations of total cholesterol, vitamin A and three carotenoids (-carotene, beta -cryptoxanthin and lutein/zeaxanthin). Older adults (aged greater than or equal to 60 y) from FIF had lower intakes of energy, vitamin B-6, magnesium, iron and zinc and were more likely to have iron and zinc intakes below 50% of the recommended amount on a given day. Older adults from FIF also had lower serum concentrations of high-density lipoprotein cholesterol, albumin, vitamin A, beta -cryptoxanthin and vitamin E. Both younger and older adults from FIF were more likely to have very low serum albumin (
