【摘要】：目的了解云南省土源性线虫人群感染现状。方法于2012-2014年对全省12个县采用整群随机抽样方法确定调查点,调查对象为3周岁以上常住居民。收集受检者粪便,采用Kato-Katz(一粪二检)法检查肠道蠕虫卵,分别计算蛔虫、鞭虫和钩虫每克粪便虫卵数(EPG),同时收集调查者的性别、年龄和受教育等情况。并将调查结果与1992年和2003年结果进行比较分析。抽取10户居民菜园、厕所周边、厨房、庭院的土样,采用改良饱和硝酸钠漂浮法查蛔虫卵。结果共调查24 870人,土源性线虫感染率为7.47%(1858/24870),与1992和2003年的19.3%和28.86%比较分别下降61.30%和74.12%。蛔虫、鞭虫、钩虫、绦虫和蛲虫感染率分别为1.21%(300/24870)、0.40%(99/24870)、6.01%(1494/24870)、0.004%(1/24870)和0.74%(2/271)。蛔虫、鞭虫和钩虫感染者的平均EPG分别为2 094、196和1082。男性和女性感染率分别为6.81%和8.07%,差异有统计学意义(χ2=14.219,P0.05);各年龄组间感染率差异有统计学意义(χ2=429.14,P0.01);不同职业和民族间感染率差异也有统计学意义(χ2职业=346.71,χ2民族=1 090.85,P均0.01);不同文化程度人群感染率差异有统计学意义(χ2=46.71,P0.01)。结论云南省人群土源性线虫感染率呈下降趋势,但在经济欠发达地区感染率仍较高,钩虫感染率下降趋势缓慢。
[Abstract]:Objective to investigate the infection status of soil-borne nematodes in Yunnan Province. Methods from 2012 to 2014, cluster random sampling method was used to determine the survey points in 12 counties of the province, and the subjects were resident over 3 years old. The feces of the subjects were collected and the intestinal worm eggs were examined by Kato-Katz (one fecal double examination). The number of eggs per gram of Ascaris lumbricoides, Trichuris and hookworm per gram of fecal eggs were calculated by (EPG),. The sex, age and education of the investigators were also collected. The survey results are compared with those in 1992 and 2003. Soil samples from 10 households of vegetable gardens, toilets, kitchens and yards were taken to detect Ascaris eggs by modified saturated sodium nitrate floating method. Results A total of 24870 people were investigated. The infection rate of soil-derived nematodes was 7.47% (1858 / 24870), which was 61.30% and 74.12% lower than that of 19.3% and 28.86% in 1992 and 2003, respectively. The infection rates of Ascaris lumbricoides, Trichuris, hookworm, tapeworm and Enterobius vermicularis were 1.21% (300 鈮，
