目的 :对托幼园所进行膳食调查 ,分析 192 31名儿童微量营养素摄入情况 ,以指导托幼园所膳食管理。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 2 0 0 0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 5 0 5 7% ,有 72 0 7%的托幼园所人均摄入量不足DRI的 5 0 % ;硫胺素摄入量占 89 95 %DRI,有 30 6 3%的园所人均摄入不足 80 %DRI;分别有2 3 4 2 %、 2 0 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。
PURPOSE: To conduct a dietary survey of nurseries and kindergartens and analyze the intake of micronutrients among 192 31 children in order to guide their dietary management. Methods: A five-day dietary survey of 111 nurseries in Liwan District of Guangzhou was conducted by weighing method. The food composition table of China was used as the basis for calculation and the reference intake of dietary nutrients of Chinese residents Quantity (DRIs) "as the evaluation index, the nutrient calculation was made with the child health care software prepared by School of Public Health, Sun Yat-sen University. Results: Calcium was the most nutrient-deficient dietary supplement for children in kindergartens, with a per capita intake of 507.7% of DRI and a per capita intake of 72.7% of nursery schools less than 50% of DRI. Thiamine intake accounted for 89 95% of the DRI, with 30 6 3% of the residents having less than 80% DRI per inhabitant; respectively, 232%, 272%, 11 71% and 63% Per capita daily intake of zinc, ascorbic acid, riboflavin, iron less than 80% of the DRIs; retinol equivalent, vitamin E, niacin, selenium adequate intake. Conclusion: The lack of calcium should be adjusted dietary structure or appropriate use of fortified foods to be improved; part of the kindergarten should adjust the dietary structure, to ensure adequate intake of thiamine, zinc, ascorbic acid, riboflavin, iron.
