本研究的目的是估计个体多不饱和脂肪酸（PUFAs）的摄入量，确定PUFAs的主要饮食来源，并估计12-60个月大的美国儿童中食用鱼类的个体比例，按年龄和种族和种族划分。美国人口的代表性样本基于选定的县。受试者：2496名12-60个月的美国儿童。n-6多不饱和脂肪酸和二十碳五烯酸（EPA）的平均每日摄入量因年龄而异，12-24个月的儿童的平均摄入量（mg或g day-1）低于49-60个月的儿童，调整能量摄入后，n6：n3比率最低。二十二碳六烯酸（DHA）的摄入量较低（20毫克，每天-1）相比，典型的婴儿摄入量，并没有随着年龄的变化。与非西班牙裔白色儿童相比，墨西哥裔美国儿童的DHA和花生四烯酸（AA）摄入量更高。在过去的30天里，53.7%的儿童吃过鱼。非西班牙裔黑人儿童比非西班牙裔白色儿童更有可能食用鱼类（64.0%对53.0%）。结果表明，相对于n-6脂肪酸，鱼类摄入和关键n-3 PUFA的患病率较低，这表明美国儿童的饮食有改进的空间。需要更多的研究来确定增加膳食中n-3 PUFA（如DHA）的摄入量如何有益于儿童健康。
This study aimed to estimate intake of individual polyunsaturated fatty acids (PUFAs), identify major dietary sources of PUFAs and estimate the proportion of individuals consuming fish among US children 12–60 months of age, by age and race and ethnicity.The study employed a cross-sectional design using US National Health and Nutrition Examination Survey data. Representative sample of US population based on selected counties. Subjects: 2496 US children aged 12–60 months. Mean daily intake of n-6 PUFAs and eicosapentaenoic acid (EPA) varied by age, with children 12–24 months of age having lower average intakes (mg or g day−1) than children 49–60 months of age and the lowest n6 : n3 ratio, upon adjustment for energy intake. Docosahexaenoic acid (DHA) intake was low (20 mg day−1) compared to typical infant intake and did not change with age. Compared to non-Hispanic white children, Mexican American children had higher DHA and arachidonic acid (AA) intake. In the previous 30 days, 53.7% of children ever consumed fish. Non-Hispanic black children were more likely than non-Hispanic white children to have consumed fish (64.0% vs. 53.0%). Results indicate low prevalence of fish intake and key n-3 PUFAs, relative to n-6 fatty acids, which suggests room for improvement in the diets of US children. More research is needed to determine how increasing dietary intakes of n-3 PUFAs like DHA could benefit child health.
