儿童时期反复感染日本血吸虫可导致形成晚期血吸虫病性侏儒症，为了观察儿童慢性血吸虫感染对生长发育的影响；我们在四川省眉山县血吸虫病流行区采用粪便血吸虫毛蚴孵化法检出日本血吸虫感染的７～１１岁患儿３４例，按性别年龄以１４与同一地区的１３６例非感染儿童进行配对观察。对两组儿童的体重、身高、坐高、头围、胸围、上臂围、小腿围、肩宽及骨盆宽等９项生长发育指标进行了测量。结果表明，除骨盆宽度两组间无显著性差异外，感染组儿童的其余指标均较非感染组儿童低（ｔ′及ｔ分别为３．８、２．３５、２．０８、１．９６、１．６６、１．９６、３．６５、１．７７，Ｐ均＜０．０５，其中体重及小腿围两项指标Ｐ＜０．０１）。表明幼年时期的感染可能影响儿童的生长发育。鉴于四川一些地区儿童为高感染年龄组，因而在血吸虫病防治工作中，儿童血吸虫病的防治应尤其重视。
Infection of Schistosoma japonicum in childhood can lead to the formation of advanced schistosomiasis dwarfism, in order to observe the impact of childhood chronic schistosomiasis infection on the growth and development; we use schistosoma japonicum in schistosomiasis endemic areas of Sichuan Province to detect schistosoma japonicum infection Thirty-four children aged 7 to 11 years old were enrolled in this study. The results were paired with 136 non-infected children in the same area by sex and age. Nine indicators of body weight, height, height, head circumference, chest circumference, upper arm circumference, calf circumference, shoulder width and pelvis width of the two groups of children were measured. The results showed that in addition to the pelvic width between the two groups showed no significant difference, the remaining indicators of infection in children than non-infected children were lower (t ’and t were 3.8,2.35,2.08,1.96 , 1.66,1.96,3.65,1.77, all P <0.05, body weight and calf circumference two indexes P <0.01). Show that infection in early childhood may affect children’s growth and development. In view of the fact that children in some areas of Sichuan Province are of high infection age group, prevention and treatment of schistosomiasis should be given special attention in the prevention and treatment of schistosomiasis.
