目的了解2014年在云南省云县人民医院门诊患者中开展土源性线虫监测情况。方法采用改良加藤厚涂片法镜检虫卵。结果在统计分析的1 002位门诊病人中,土源性线虫总感染率6.79%[95%可信区间(CI):5.34%~8.57%],其中蛔虫、钩虫和鞭虫感染率分别为1.70%(95%CI:1.02~2.76)、4.69%(95%CI:3.50~6.24)和0.80%(95%CI:0.37~1.83)。学龄前(<7岁)儿童感染率最高,15.63%(95%CI:9.81~23.09);与≥26岁年龄组比较,多因素Logistic回归分析调整后比值比(OR)为2.97(1.68~5.79)。感染无季节性差异(χ~2=3.17,P=6743)。结论云南省云县人民医院门诊土源性线虫感染率学龄前儿童较高。
Objective To understand the monitoring of soil-borne nematodes among outpatients in Yunxian People’s Hospital of Yunnan Province in 2014. Methods The modified Kato thick smear method was used to examine the eggs. Results The total infection rate of soil-borne nematodes was 6.79% (95% confidence interval (CI): 5.34% ~ 8.57%) among the 1 002 outpatients who were statistically analyzed. The infection rates of roundworm, hookworm and whipworm were 1.70 % (95% CI: 1.02-2.76), 4.69% (95% CI: 3.50-6.24) and 0.80% (95% CI: 0.37-1.83). The highest infection rate in preschool children (<7 years old) was 15.63% (95% CI: 9.81 ~ 23.09). Compared with the age group of ≥26 years, the multivariate Logistic regression analysis showed that the odds ratio was 2.97 (1.68 ~ 5.79 ). No seasonal difference in infection (χ ~ 2 = 3.17, P = 6743). Conclusions The prevalence of soil-borne nematodes in Yunxian People’s Hospital of Yunnan Province is higher in preschool children.
