摘　　要：为了解安徽省部分地区人群肠道原虫感染现状,按照生态区分布,从安徽省4个生态区中各随机抽取一个县(区)作为调查县,分别抽取了绩溪县、马鞍山市博望区、定远县和利辛县。每个县(区)随机整群抽取至少200名常住居民作为调查对象,采集调查对象粪便,用碘染色法镜检原虫包囊并计算人群感染率。率的比较使用χ2检验,多因素分析使用二元logistic回归。结果显示,共调查826人,主要检出3种肠道原虫,分别是结肠内阿米巴原虫、蓝氏贾第鞭毛虫以及人芽囊原虫。人群总感染率4.0%,其中结肠内阿米巴原虫感染率3.1%,蓝氏贾第鞭毛虫感染率0.7%,人芽囊原虫感染率0.1%。男女感染率分别为2.4%和5.3%;>60岁人群感染率2.5%,≤60岁人群感染率5.6%;学龄前儿童、学生、农民、家务及待业和其他非农人群5种职业的感染率分别为4.7%、5.1%、3.1%、6.0%和12.8%;文盲及半文盲、小学及初中、高中及以上3种文化程度的感染率分别为2.7%、4.0%和11.8%。二元logistic回归结果显示,女性、非农业职业和文化程度较高是肠道原虫感染的危险因素。结果表明,安徽省部分地区人群肠道原虫感染率总体较高,女性、非农业人口以及文化程度较高者应作为今后防治工作的重点对象。To understand the status of intestinal protozoa infection in endemic areas of Anhui province by sampling survey.According to the distribution of ecological zones,one county(district)was randomly selected from each of the four ecological zones in Anhui Province as sampling points,and Jixi County,Ma′anshan Bowang District,Dingyuan County and Lixin County were enrolled in present survey respectively.At least 200 permanent residents were selected from each county(district)by random cluster sampling.Feces samples of these people were collected and protozoa cysts were examined under microscopes by iodine staining.Theχ^(2)test was used for comparison of rates and binary logistic regression was used for multivariate analysis.A total of 826 people were investigated,and three protozoa species were found,namely Entamoeba coli,Giardia lamblia and Blastocystis hominis.The total infection rate of the three species was 4.0%,among which the infection rates of E.coli,G.lamblia and B.hominis were 3.1%,0.7%and 0.1%,respectively.The infection rates of male and female were 2.4%and 5.3%,respectively(χ^(2)=4.440,P=0.035);the rate was 2.5%in>60 years and 5.6%in≤60 years(χ^(2)=5.021,P=0.025).The total infection rate of preschool children,students,farmers,housework,unemployed persons,and other non-agricultural population was 4.7%,5.1%,3.1%,6.0%,and 12.8%,respectively,and the difference was shown statistically significant(χ^(2)=10.085,P=0.039);the rate of illiterate and semi-illiterate,primary school and junior middle school,senior high school and above were 2.7%,4.0%and 11.8%,respectively(χ^(2)=6.297,P=0.043).The results of binary logistic regression showed that female,those of non-agricultural occupation and high educational level were the risk factors for intestinal protozoa infection.The infection rate of intestinal protozoa in part areas of Anhui is generally high,and women,non-agricultural population and people with higher education should be the key objects of future prevention and control work.
