【摘要】：目的了解河南省豫东地区肠道寄生虫感染的流行现状,为该地区肠道寄生虫感染的防治提供科学依据。方法 2014年11月-2015年6月按照经济条件和地理方位进行分层整群抽样,随机选择豫东地区的临颍县、濮阳县、台前县、太康县、西平县、息县、项城市、新郑市、虞城县等9个县(市)26个调查点,采集人群粪样,采用改良加藤厚涂片法检查肠道蠕虫感染情况,钩蚴试管滤纸培养法鉴别钩虫(Ancylostoma sp.)虫种,3~6岁儿童采用透明胶纸肛拭法检查蛲虫(Enterobius vermicularis)感染情况,碘液染色法检查肠道原虫感染情况。收集各调查点的主要饮用水源、农民年人均纯收入等基本信息。将不同地区感染率进行标准化后进行比较。不同虫种、性别、年龄和职业以及其他相关因素的感染率间差异比较采用卡方检验。结果共收集粪样6 696份,检出肠道蠕虫6种,肠道原虫4种。肠道寄生虫总感染率为1.57%(105/6 696),其中肠道蠕虫和原虫感染率分别为0.91%(61/6 696)和0.66%(44/6 696)。感染率较高的3种肠道寄生虫分别为蛲虫(0.36%,24/6 696)、人芽囊原虫(Blastocystis hominis)(0.30%,20/6 696)和蛔虫(Ascaris lumbricoides)(0.19%,13/6 696)。3~6岁儿童蛲虫感染率为2.23%(15/674),其中肛拭蛲虫感染率为1.93%(13/674)。7份钩蚴经鉴定均为十二指肠钩虫(Ancylostoma duodenale)。肠道寄生虫感染率较高的3个县(市)分别是项城市(4.24%)、新郑市(3.51%)和太康县(3.34%)。男性和女性肠道寄生虫感染率分别为1.71%(55/3 214)和1.44%(50/3 482),两者差异无统计学意义(χ~2=0.82,P0.05)。不同文化程度人群中,肠道寄生虫感染率最高的为高中/中专组2.11%(10/473),与其他组比校,差异无统计学意义(χ~2=2.41,P0.05)。不同年龄组人群中,15~29岁组人群的肠道寄生虫感染率最高,为2.38%(21/884),与其他年龄组比较,差异有统计学意义(χ~2=9.39,P0.01)。不同职业人群中,学龄前和学生人群的肠道寄生虫感染率较高,为2.5%(24/720)和2.09%(24/1 148),与其他职业人群比较,差异有统计学意义(χ~2=9.93,P0.05)。饮用水为井水的调查点人群肠道寄生虫感染率为1.21%(31/2 562),高于自来水饮用人群的0.65%(27/4 134)(χ~2=5.71,P0.05)。调查点农民年人均纯收入为1 200~11 600元,中位数为5 604.5元,肠道寄生虫感染率随农民年人均纯收入的增加而降低(χ~2=11.08,P0.01)。结论河南省豫东地区人体重点寄生虫感染情况较前两次调查有显著下降,学龄前儿童、学生人群是今后监测的重点人群。
[Abstract]:Objective to investigate the epidemic situation of intestinal parasite infection in eastern Henan Province, and to provide scientific basis for the prevention and treatment of intestinal parasite infection in this area. Methods from November 2014 to June 2015, 26 survey sites in 9 counties (cities), such as Linying County, Puyang County, Taiqian County, Taikang County, Xiping County, Xixian County, Xiangcheng City, Xinzheng City and Yucheng County, were randomly selected according to economic conditions and geographical location. The fecal samples were collected and the intestinal worm infection was examined by modified Kato thick smear method. Identification of hookworm (Ancylostoma sp.) by in vitro filter paper culture of hookworm The infection of Enterobius vermicularis (Enterobius vermicularis) was detected by transparent adhesive paper anal swabs in children aged 3 years and 6 years old, and the infection of Enterobius vermicularis was detected by iodine staining. Collect the main drinking water sources, farmers' annual per capita net income and other basic information. The infection rate in different areas was compared after standardization. Chi-square test was used to compare the infection rate among different species, sex, age, occupation and other related factors. Results A total of 6696 fecal samples were collected and 6 species of intestinal worms and 4 species of intestinal protozoa were detected. The total infection rate of intestinal parasites was 1.57% (105 脳 6696). The infection rates of intestinal worms and protozoa were 0.91% (61 鈮，
