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.
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.
本研究旨在按年龄、种族和民族估计美国12至60个月大儿童个体多不饱和脂肪酸(PUFA)的摄入量,确定PUFA的主要饮食来源,并估计食用鱼类的儿童比例。该研究采用横断面设计,使用美国国家健康和营养检查调查数据。基于选定县的美国人口代表性样本。
2496名12至60个月大的美国儿童。n-6多不饱和脂肪酸和二十碳五烯酸(EPA)的平均每日摄入量随年龄而异,在调整能量摄入后,12至24个月大的儿童平均摄入量(毫克或克/天)低于49至60个月大的儿童,且n6:n3比例最低。与典型婴儿摄入量相比,二十二碳六烯酸(DHA)摄入量较低(20毫克/天),且不随年龄变化。与非西班牙裔白人儿童相比,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30天内,53.7%的儿童曾食用过鱼类。非西班牙裔黑人儿童比非西班牙裔白人儿童更有可能食用过鱼类(64.0%对53.0%)。结果表明,相对于n-6脂肪酸,鱼类摄入量和关键n-3多不饱和脂肪酸的患病率较低,这表明美国儿童的饮食仍有改善空间。需要更多研究来确定增加DHA等n-3多不饱和脂肪酸的饮食摄入量如何有益于儿童健康。
