广州城区托幼园所儿童微量营养素摄入情况分析

目的：对托幼园所进行膳食调查，分析19231名儿童微量营养素摄入情况，以指导托幼园林膳食管理。方法：采用称重法对广州市荔湾区111间托幼园所进行5天的膳食调查，以中国的食物成分表为计算依据，用2000年修订的“中国居民膳食营养素参考摄入量（DRIs)”作为评价指标，用中山大学公共卫生学院编制的儿童保健软件进行营养素计算。结果：钙是托幼园所儿童膳食缺乏最明显的营养素，人均摄入量占DRI的50．57％，有72．07％的托幼园所人均摄入量不足DRI的50％；硫胺素摄入量占89．95％DRI，有30．63％的园所人均摄入不足80％DRI；分别有23．42％、20．72％、11．71％、6．30％的托幼园所人均每日摄入锌、抗坏血酸、核黄素、铁不足80％DRIs；视黄醇当量、维生素E、烟酸、硒摄入充足。结论：对钙的缺乏应调整膳食结构或适当使用强化食品加以改善；部分托幼园所应调整膳食结构，保证硫胺素、锌、抗坏血酸、核黄素、铁摄入充足。

Dietary intake of micronutrients of 19231 children in 111 kindergartens or nurseries in Linwan Guangzhou

Objective: Based in the data collected in dietary survey, the dietary intake of some micronutrients were calculated Methods: Five day food weighed method for dietary survey was used in kindergartens or nurseries Nutrients intakes were calculated with the Chinese food composition talble Results: Calcium was the most insufficient nutrient in collective children, calcium intake per person was 50 57% DRI and there was 72 07% of Kindergartens or nurseries whose children consumed calcium less than 80% DRI Thiamine intake per person was 89 95% DRI and there was 30 63% of kindergartens or nurseries whose children consumed thiamine less than 80% DRI There was 23 42%? 20 72%? 11 71% and 6 3% of kindergartens or nurseries whose children consumedzinc,ascorbic acid,riboflavin and iron less than 80% DRIs,individually The intakes of retinal equivalent,vitamin E,niacin and selenium were sufficient Conclusion:To improve the dietary calcium intake of collective children,milk and dairy product consumption are recommended and food fortification with calcium may be feasible as well Some kindergartens or nurseries should make balanced diet insure those children intake adequate thiamine,zinc ascorbic acid,riboflavin and iron
