小儿幽门螺杆菌感染调查

１９９３年６月－１９９４年６月期间，采用ＥＬＩＳＡ检测血清中抗幽门螺杆菌尿素酶抗体，对３９４名小儿各年龄组自然人群感染率进行了调查。总体平均阳性率为１５．７％，具有随年龄增加而增加的总趋势，至１２岁组时阳性率达３０％。其中１－３岁及７岁组阳性率相对较高，可能与家庭及学校内密切接触有关。此外，反复发生腹痛者其阳性率较无症状者明显增高。

An Epidemiological Survey on Helicobacter pylori Infection in Children

In this study serum anti-urease antibodies of Helicobacter pylori was examined in order to investigate the prevalence of H.pylori infection in 394 children between age 1 and 13.The results showed that the average infection rate was 15.7%with a tendency of increase infection rate with age,and by the age of 12 the H. pylori infection rate reached 30%,which was higher than those found in developed countries. We also noticed that there was a comparatively higher serapositivity among 1 and 7 year olds.This may possibly be due to the close contact between family members and school mates. In addition, the serum positive rate of antibody to H. pylori urease in children with recurrent abdominal pain was much higher than those asymptomatic children(P<0.05).
