肠道寄生虫感染是撒哈拉以南非洲的主要公共卫生问题之一。其分布主要与个人卫生、环境卫生和清洁用水有限有关。事实上，不同地区各种肠道寄生虫感染患病率的流行病学信息是制定适当控制措施的先决条件。因此，本研究的目的是评估学龄儿童肠道寄生虫感染的患病率和相关的危险因素。这项以学校为基础的横断面研究于2012年4月至2012年6月在贡达尔大学社区学校进行。采用系统随机抽样方法选择研究受试者。数据收集通过直接访谈，使用预先测试的问卷。收集粪便标本，采用直接盐水涂片和甲醛-乙醚浓缩法，在显微镜下检查肠道寄生虫卵、包囊和滋养体的存在。使用SPSS 16版软件进行数据输入和分析。在304例研究受试者中，104例（34.2%）感染了一种或多种肠道寄生虫。男性患病43例（32.1%），女性患病61例（35.9%）。与其他年龄组相比，10-12岁年龄组的肠道寄生虫患病率较高。肠道寄生虫以微小膜壳绦虫为主，其次为溶组织内阿米巴和蛔虫，分别为42例（13.8%）、28例（9.2%）和18例（5.9%）。洗手习惯和交通方式与肠道寄生虫感染有统计学相关性。1 - 3年级儿童肠道蠕虫感染率高于4 - 8年级儿童（p = 0.031）。肠道寄生虫在不同程度上流行的学童。蠕虫感染率高于原生动物。应考虑采取措施，包括个人卫生、环境卫生、供水和治疗方面的教育，以减少肠道寄生虫的流行。
Intestinal parasitic infections are among the major public health problems in Sub-Saharan Africa. Their distribution is mainly associated with poor personal hygiene, environmental sanitation and limited access to clean water. Indeed, epidemiological information on the prevalence of various intestinal parasitic infections in different localities is a prerequisite to develop appropriate control measures. Therefore, the aim of this study was to assess the prevalence of intestinal parasitic infections and associated risk factors among schoolchildren. This school-based cross-sectional study was undertaken at the University of Gondar Community School from April 2012 to June 2012. Study subjects were selected using a systematic random sampling method. Data were gathered through direct interview by using a pretested questionnaire. The collected stool specimens were examined microscopically for the presence of eggs, cysts and trophozoites of intestinal parasites using direct saline smear and formol-ether concentration methods. Data entry and analysis were done using SPSS version 16 software. Out of 304 study subjects, 104 (34.2%) were infected with one or more intestinal parasites. The prevalence rate was 43 (32.1%) for male and 61 (35.9%) for female. The prevalence of intestinal parasites was high in age group of 10–12 years compared to other age groups. The predominant intestinal parasite was Hymenolepis nana, followed by Entamoeba histolytica/dispar and Ascaris lumbricoides with 42 (13.8%), 28 (9.2%), 18 (5.9%), respectively. Hand washing practice and ways of transportation were statistically associated with intestinal parasitic infections. Children in grades 1 to 3 had a higher prevalence of intestinal helminthic infection than those in grades 4 to 8 (p = 0.031). Intestinal parasites were prevalent in varying magnitude among the schoolchildren. The prevalence of infections were higher for helminths compared to protozoa. Measures including education on personal hygiene, environmental sanitation, water supply and treatment should be taken into account to reduce the prevalence of intestinal parasites.
