摘要
目的研究平衡膳食对山区学龄儿童营养状况的影响。方法2004年11月份在某山区选取二年级小学生60名,分为2组,每周5天在学校进食3餐,干预组根据营养素推荐摄入量配餐,对照组则保持日常膳食模式,实验期为30天,观察实验前后两组儿童营养状况的变化。结果干预组膳食结构合理,营养素供给充足,儿童的体格发育和营养状况得到明显改善,对照组由于膳食结构不合理,营养素摄入量普遍低下,影响了儿童的正常生长发育。结论在贫困地区以食物为基础的营养干预可改善儿童生长发育和营养状况。
Objective To study the effect of balanced diet on the nutrition status of primary schoolchildren in the mountain area in November 2004. Methods All the subjects aged 7-9 years old were divided into intervention group and control group. The balanced diet was provided for the intervention group and the control group was maintained on their usual diet for 30 days in December. The antroprometric and nutritional status of the subjects were checked before and after the study. Results The growth and nutritional status of the intervention group improved significantly. However the unbalanced diet in the control group affects the normal growth of the children because the usual diet can not meet the nutrient requirement. Conclusion The nutrition intervention can improve the growth and nutritional status of the primary schoolchildren in the mountain area.
