采用人体测量及瑞文氏智商（ＩＱ）等测定方法，在浙江省农村对感染蛔虫和未感染蛔虫的小学生各２００例进行调查。感染学生每年驱虫２次，连续３年后复查。结果表明，驱虫前感染组学生的身高、体重、皮皱厚度及血色素等各项指标的平均值低于非感染的对照组；病例组有平均ＩＱ也落后于对照组，差异均具有统计学意义。驱虫后各项测量指标明显上升，上升的各平均值分别与对照组比较，其差异无显著性意义。表明肠道蛔虫长期反复感染对儿童的健康发育有较明显的影响。
Using body measurement and Reynolds’ IQ (IQ), 200 cases of primary and secondary school students infected with roundworms and non-infected roundworms were investigated in the rural areas of Zhejiang Province. Infected students deworming twice a year for three years after the review. The results showed that the average value of each index such as height, weight, furrow thickness and hemoglobin of the students before deworming infection was lower than that of the non-infected control group. The average IQ of the patients in the group also lagged behind that of the control group, with statistical differences significance. After deworming each measurement index increased significantly, the average of each rise compared with the control group, the difference was not statistically significant. Show that long-term intestinal Ascaris infection has a more significant impact on the healthy development of children.
