摘 要:作者在前一个实验工作的基础上进一步扩大样本,对670名4岁以下儿童进行了为期二年的补充大剂量VA的实验观察,用双盲法对实验组儿童每6个月补充20×104IUVA,由乡村医生每周访问儿童家长,记录儿童患病情况。结果表明对亚临床VA缺乏地区儿童补充大剂量VA能降低腹泻发生率,且其效果在疾病高发月份更明显,结果还表明血清VA低的儿童补充VA比血清VA水平较高的儿童效果明显;但对呼吸道感染性疾病虽然在疾病高发月份实验组发病比对照组低,但总的差异不明显。作者还对疾病资料收集方法进行了讨论。Based on the previous study on the impact of large dose of VA supplementation on child morbidity, the investigators studied it again with larger sample size(670 under 4 year children) and in longer period(2 years).By double blinded method, 20 × 104 IU VA and placebo were given to the studied groups every 6 months, and incidence of diarrhea and respiratory disease was recorded by the village doctors by home visit every week. The results showed that the large dose VA supplementation lowered the incidence of diarrhea of children, especially during the high prevalence season, and the effect was more significant in child with lower serum VA than that with higher serum VA level. Although the incidence of respiratory diseases in study group was lower than that in the control, there were no significant difference between the 2 groups.
