补充β-胡萝卜素和维生素A对儿童常见病发病率及生长发育的影响

The Effect of Supplementation with Vitamin A and β－carotene on the Growth and Development of Children

对132名6个月～7岁维生素A缺乏及临界缺乏儿童进行了3个月的补充β-胡萝卜素及维生素A试验，结果发现：补充β-胡萝卜素组，维生素A缺乏儿童及临界缺乏儿童血清维生素A水平均明显提高（P均＜0.01），还能促进儿童生长，体重平均多增加0.3kg(P∠0.05）,3个月内平均发病天数比对照组减少了7d（P＜O.05)，暗适应时间平均缩短了8s（P＜0.01）。且补充β-胡萝卜素组与补充维生素A组之间各项指标间差异无显著性意义（P均＞O.05）。本研究说明，在我国农村增加儿童摄入富含β-胡萝卜素的深色蔬菜可作为防治儿童维生素A缺乏的有效措施。
