对北京城区１７４所幼儿园的１６５７１名学龄前儿童进行了肠道蠕虫感染调查，结果蛲虫、蛔虫和粪类圆线虫感染率分别为１０．４％、０．１％和１．４％，将２４所蛲虫感染率较高的幼儿园分为２组，分别实施选择性驱虫（Ａ组）与选择性驱虫辅以健康教育等其他措施（Ｂ组）两种防治方案，结果Ａ组防治１年后的感染率与防治前相比无显著下降（Ｐ＞０．０５），Ｂ组则明显降低（Ｐ＜０．０１）。提示健康教育等措施可提高防治效果。

Survey and Control of Intestinal Helminthiasis in Preschoolers in the Beijing Proper

nvestigation on intestinal helminthiasis was carried out in 16 571 preschoolers of 174 kindergartens in the Beijing proper. Among them,the infection rates of Enterobius vermicularis ,Ascaris lumbricoides and Strongyloides stercoralis were 10. 4%,0. 1% and 1.4% respectively. Twenty four kindergartens with higher infection rates of pinworm were divided into groups A and B. For controlling enterobiasis ,two different control schemes were undertaken:Selective chemotherapy (A) and the combination of selective chemotherapy and health education(B). The results showed that the pinworm average infection rate of children in group A dropped from 10. 7% to 9. 6% (P>0. 05)and in group B the rate from 13. 5% to 6. 2% (P<0. 01). The reduction rate of group B was higher than that of group A (P<0. 01). It could be concluded that comprehensive control scheme of selective chemotherapy and health education might be the most practical scheme for the control of enterobiasis at present.
