Background. Globally, over 600 million school children are living with intestinal parasites. The prevalence of intestinal parasitic infections (IPIs) among school children in Ethiopia and the Amhara region is 52% and 51%, respectively. The present study aimed to determine the prevalence and associated risk factors of IPIs among primary school children in Dera district, Northwest Ethiopia. Methods. A school-based cross-sectional study was conducted from December 2019 to February 2020. The study used a structured pretested questionnaire and stool tests to obtain epidemiological and disease data. Data were analyzed using appropriate univariate and multivariable logistic regression methods by statistical package for social science (SPSS) version 25.0. Results. Of the 382 students who were examined for IPIs, 238 (62.3%) (61.8% males, 62.8% females) were positive for one or more IPIs. One hundred thirty-six (35.6%), 98 (25.7%), and 4 (1.05%) were single, double, and triple infections, respectively. Out of the nine species of IPIs detected, Entamoeba sp. was the predominant species (29.6%) followed by hookworm (21.7%), Schistosoma mansoni (11.3%), Taenia sp. (9.2%), Giardia lamblia (5.2%), and Ascaris lumbricoides, Hymenolepis nana, and Enterobius vermicularis (4.2%) each, and Trichuris trichiura (0.5%). Family size greater than five (AOR = 1.8; 95% CI: 1.004, 3.13), open field school waste disposal (AOR = 15.88; 95% CI: 1.91, 132.1), and lack of knowledge about intestinal parasitic infection (AOR = 1.8; 95% CI: 1.1, 3.2) were the independent risk factors associated with the overall prevalence of IPIs. Conclusions. The prevalence of intestinal parasitic infection was high in the Dera district. Health education, extending school-based deworming, and mass treatments are recommended.

埃塞俄比亚西北部德拉区小学生肠道寄生虫感染的患病率和危险因素


背景。全球有超过 6 亿学童患有肠道寄生虫。埃塞俄比亚和阿姆哈拉地区学童肠道寄生虫感染（IPIs）的患病率分别为 52% 和 51%。本研究旨在确定埃塞俄比亚西北部德拉地区小学生中 IPI 的患病率和相关风险因素。方法。 2019年12月至2020年2月进行了一项以学校为基础的横断面研究。该研究使用结构化预测试问卷和粪便测试来获取流行病学和疾病数据。通过社会科学统计软件包 (SPSS) 25.0 版，使用适当的单变量和多变量逻辑回归方法对数据进行分析。结果。在接受 IPI 检查的 382 名学生中，238 名学生（62.3%）（61.8% 男性，62.8% 女性）的一种或多种 IPI 呈阳性。单一、双重和三重感染分别为 136 例（35.6%）、98 例（25.7%）和 4 例（1.05%）。在检测到的九种 IPI 中，内阿米巴属 (Entamoeba sp.)。是优势种（29.6%），其次是钩虫（21.7%）、曼氏血吸虫（11.3%）、带绦虫。 (9.2%)、贾第鞭毛虫(5.2%)、蛔虫、膜壳虫和蛲虫(4.2%)，以及鞭毛虫(0.5%)。家庭人数超过五人（AOR = 1.8；95% CI：1.004，3.13）、露天学校废物处理（AOR = 15.88；95% CI：1.91、132.1）以及缺乏对肠道寄生虫感染的了解（AOR = 1.8） ; 95% CI: 1.1, 3.2) 是与 IPI 总体患病率相关的独立危险因素。结论。 德拉区肠道寄生虫感染患病率较高。建议进行健康教育、扩大学校驱虫和集体治疗。
