儿童营养与身体发育状况关系的探讨

目的：对儿童营养与身体发育状况的关系和10年前相比进行探讨。方法：按照常规营养调查法分别于1989年和1999年对泰安市同一所幼儿园的163名和175名儿童进行膳食调查，体格检查及生化检验。结果：10年后的膳食结构更趋于合理。蛋白质、硫胺素、尼克酸供给量均已达到或超过RDA；而钙及视黄醇仅约为RDA的50％及70％还存在不足。目前通过膳食结构的改善儿童身高、体重、血红蛋白测定均有明显增加（P＜0．01）；贫血率由10年前的17．5％降至4．7％。结论：膳食结构趋于合理对儿童身体健康发育起至关重要的作用。

Relationship between nutrient status and physical development of children

Objective: To study the correlation between meal nutrition and physical development of preschool children, and on which comparisons were made in 1989 and 1999 Methods: Surveys on meal, physical status and routine biochemical tests were carried out separately among 163 and 175 children of the same kindergarden in Taian in 1989 and 1999 Results: In 1999, the meal component tended to be more scientific The supplement of proteins, thiamine and niacin reached RDA level or beyonded it; the supplement of calorie, iron, riboflavin and vitamin C nearly reached RDA level; but the supplement of calcium and vitamin A were only at 50% and 70% RDA levels The average height and weight of children increased noticeably in the same age group compared with those of ten years ago (P<0 01) The rate of anemia decreased from 17 5% in 1989 to 4 7% in 1999 Conclusion: Balanced nutrition meal plays a critical role in children's physical development
