为寻求适合广大农村预防佝偻病安全,有效的方法,进行了使用维生素D预防的干预实验。结果为:VD预防组的总发病率为23.05％,对照组的发病率为55.47％,保护率为58.45％。其中每日投药组,每月投药组与每季投药组的保护率分别为55.30％;65.48％与54.93％。提示,本干预实验取得较满意的效果。研究结果还显示虽经VD预防佝偻病发病大幅度下降,但晋城郊区佝偻病发病率仍较高,说明该地除用VD预防外,必须采取综合性预防措施,才能使佝偻病发病率进一步下降。
In order to find a safe and effective method suitable for prevention of rickets in rural areas, intervention experiments using vitamin D prevention were conducted. The results were as follows: the overall incidence of VD prevention group was 23.05%, the incidence of the control group was 55.47%, the protection rate was 58.45%. Among them, the daily drug protection group, the monthly drug administration group and the quarterly drug administration group were 55.30%, 65.48% and 54.93% respectively. Tip, the intervention experiment to obtain more satisfactory results. The results also showed that although the incidence of rickets by VD dropped significantly, but the incidence of rickets in the suburbs of Jincheng is still high, indicating that in addition to the use of VD prevention in this area, we must take comprehensive preventive measures in order to make the incidence of rickets decline further.
