目的探讨DR Is在评价学龄儿童膳食营养现状中的应用,为进一步采取膳食干预措施提供依据。方法采用分层整群抽样的方法,在唐山市2所小学选取各年级小学生634名,采用5 d膳食调查和食物摄取频率调查结合的方法进行调查,对结果用DR Is进行评价。结果学龄儿童脂肪能量来源较高,碳水化合物能量来源偏低;晚餐能量偏低,零食供能约占20%。烟酸、硒摄入充足的占85%以上;蛋白质摄入充足的占50%,但来源较好。视黄醇、核黄素、抗坏血酸、硫胺素和锌摄入不足的分别占34%,31%,21%,15%和59%,处于不足和充足之间的分别占14%,15%,27%,28%和56%。钙平均摄入量远低于AI,有30.9%的儿童钙摄入量低于AI的半数;79.7%的儿童总铁摄入量达到了AI,但来源较差。结论应合理解释膳食摄入资料,积极改善学龄儿童的膳食结构。 Objective To explore the application of DR Is in assessing the status of dietary nutrition in school-age children and provide the basis for further dietary interventions. Methods By stratified cluster sampling method, 634 pupils of all grades were selected from 2 primary schools in Tangshan City. The 5-day dietary survey and the frequency of food intake were used to investigate the results. DR Is was used to evaluate the results. Results The school-age children had higher sources of fat energy and lower energy sources of carbohydrates. Dinner energy was lower and snacking energy accounted for about 20%. Niacin, selenium intake accounted for more than 85%; protein intake accounted for 50%, but the source is better. The intake of retinol, riboflavin, ascorbic acid, thiamine and zinc accounted for 34%, 31%, 21%, 15% and 59% respectively, accounting for 14%, 15% , 27%, 28% and 56%. Calcium intake was much lower than AI, 30.9% of children had lower calcium intake than AI; 79.7% of children reached AI, but their sources were poor. Conclusion Dietary intake should be properly explained and the dietary structure of school-age children should be actively improved.
