This study aimed to assess the prevalence and risk factors of intestinal schistosomiasis in students at Bochesa Elementary School in the wetlands of Lake Ziway.
A cross-sectional study of 384 students was conducted in May 2016. Intestinal schistosomiasis was examined using the Kato-Katz technique. For the association between the prevalence of intestinal schistosomiasis and categorical variables, the chi-square (χ) test was used. A binary logistic regression was applied.
The overall prevalence of intestinal schistosomiasis was 25.52%. Males were more infected (17.45%) than women (8.07%), and the difference was significant (χ = 17.756; <0.05). Lower grade (1-4) students were more infected (20.83%) than grade 5-8 students (4.69%), and the difference was significant (χ = 19.558; <0.05). Age groups of 7-14-year-old students were more infected (24.74%) than >15-year-old students (0.78%), and the difference was significant (χ = 4.788; <0.05).
The result implied that the wetlands of Lake Ziway are conducive to schistosomiasis. Students should receive health education on the mode of schistosomiasis transmission and its prevention methods, and a buffer zone for the wetlands should be identified. Praziquantel treatment is crucial in reducing intestinal schistosomiasis in students.
本研究旨在评估齐瓦湖湿地博切萨小学学生肠道血吸虫病的患病率及危险因素。
2016年5月对384名学生进行了横断面研究。采用加藤厚涂片法检查肠道血吸虫病。对于肠道血吸虫病患病率与分类变量之间的关联，使用卡方（χ）检验。应用二元逻辑回归分析。
肠道血吸虫病的总体患病率为25.52%。男性感染率（17.45%）高于女性（8.07%），差异有统计学意义（χ = 17.756；<0.05）。低年级（1 - 4年级）学生感染率（20.83%）高于5 - 8年级学生（4.69%），差异有统计学意义（χ = 19.558；<0.05）。7 - 14岁年龄组学生感染率（24.74%）高于15岁以上学生（0.78%），差异有统计学意义（χ = 4.788；<0.05）。
结果表明齐瓦湖湿地有利于血吸虫病传播。学生应接受关于血吸虫病传播方式及其预防方法的健康教育，应确定湿地的缓冲区。吡喹酮治疗对于降低学生肠道血吸虫病至关重要。
