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 5 0 %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 0 1) ;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
Objective To investigate the relationship between children’s nutrition and physical development status compared with 10 years ago. Methods According to routine nutrition survey, dietary survey, physical examination and biochemical test were performed on 163 children and 175 children in the same kindergarten in Tai’an City in 1989 and 1999 respectively. Results 10 years later the diet structure tends to be more reasonable. The supply of protein, thiamine and nicotinic acid all reached or exceeded RDA. However, calcium and retinol were only about 50% and 70% of RDA, respectively. At present, children’s height, weight and hemoglobin were significantly improved by the improvement of dietary structure (P <0.01); the rate of anemia dropped from 17 5% to 47% 10 years ago. Conclusion The dietary structure tends to be reasonable and plays an important role in the healthy development of children
