摘　　要：目的了解云南省腾冲市住院人群人芽囊原虫感染情况及其影响因素。方法采用横断面调查的方法对云南省腾冲市人民医院的住院人群进行问卷调查,并采集粪便,提取核酸进行PCR检测。采用单因素分析和Logistic回归分析的方法对人芽囊原虫感染的影响因素进行分析。结果研究共招募507名研究对象,其年龄中位数为52岁(95% CI :51—55),其中男性260人,年龄中位数为53岁(95% CI :53—55),女性247人,年龄中位数为51岁(95% CI :49—54)。人芽囊原虫的感染率为9.47%(48/507,95% CI :7.13—12.44)。非水冲厕所( OR =3.248,95% CI :1.245—8.473)、饮用生水( OR =3.11,95% CI :1.557—6.213)和贫血( OR =2.601,95% CI :1.245—8.473)与人芽囊原虫的感染的有统计学关联。人芽囊原虫感染和腹胀( OR =0.284,95% CI :0.067—1.199)、食欲不振( OR =0.762,95% CI :0.330—1.758)、皮肤瘙痒( OR =0.82,95% CI :0.312—2.156)和便秘( OR =1.462,95% CI :0.621—3.419)都没有统计学关联。结论人芽囊原虫感染率较高,非水冲厕所和饮用生水是影响人芽囊原虫感染的主要因素。提高健康教育知识,改善卫生条件可降低人芽囊原虫的感染。In order to understand the epidemiology characteristic and risk factors for Blastocystis hominis (B. hominis) infection, a cross-sectional study was conducted in the inpatients in a community hospital in Tengchong City, Yunnan Province. After obtaining informed consent from the subjects, stool sampl es were collected during July 2016 to March 2017. Polymerase chain reaction (PCR)was used to detect B. hominis . A structured questionnaire was used to record the demographic information and clinical symptoms for each subjects. 507 subjects enrolled in the study. The median age was 52 years old(95% CI :51-55) including 260 males with the median age of 53 years old (95% CI :53-55)and 247 females with median age of 51 years old(95% CI :49-54), and the detection rate of B. hominis was 9.47%(48/507,95% CI :7.13-12.44).Non-flush toilet( OR =3.248,95% CI :1.245-8.473), drinking unboiled water( OR =3.11,95% CI :1.557-6.213)and anemia( OR =2.601, 95% CI :1.245-8.473)was found be relevant to B. hominis infection. No significant difference was observed between B. hominis infection and clinical symptoms such as to abdominal distension ( OR =0.284,95% CI :0.067-1.199), inappetence ( OR =0.762,95% CI :0.330-1.758), itchy skin( OR =0.82,95% CI :0.312-2.156) and constipation( OR =1.462,95% CI :0.621-3.419). The infection rate of B. hominis is higher in rural area than other areas. Drinking unboiled water and non-flush toilet were the main factors affecting the B. hominis infection. Improving health education knowledge and improving sanitation can reduce the B. hominis infection.
