Soil-transmitted helminths (STHs) are widespread in underdeveloped countries. In Ethiopia, the prevalence and distribution of helminth infection varies by different exposing risk factors. We therefore investigated the prevalence of and risk factors of STHs infection in school children living in Ambo town, west Shoa Ethiopia.
In 2014/15, among 375 school children planed to be included in this study, only 321 school children were recruited in the study. Data onto school children from different schools were collected, including stool samples for qualitative STHs analysis. Questionnaire data on various demographic, housing and lifestyle variables were also available.
Prevalence of any STHs infection was 12.6%. The respective prevalence of major soil-transmitted helminths is Ascaris (7.8%), Hookworm (2.8%) and Trichuris (2.2%). This study result shows STHs prevalence varies regards to age, sex, latrine use, family size and nail trimming.
The results of the present study indicated that the percentage of positive finding for STHs in Ambo area is low. Besides, Large Family size, not nail trimming and unavailability of improved latrine were identified as predisposing factor for STHs infections. All school children enrolled and not enrolled in this study should be treated twice a year until the prevalence falls below the level of public health importance.
土壤传播的蠕虫(STH)在不发达国家广泛存在。在埃塞俄比亚,蠕虫感染的流行率和分布因不同的暴露风险因素而异。因此,我们调查了生活在埃塞俄比亚西部绍阿州安博镇的学童中STH感染的流行率和风险因素。
在2014/15年,计划纳入本研究的375名学童中,仅有321名学童被招募入研究。收集了来自不同学校学童的数据,包括用于STH定性分析的粪便样本。还获取了关于各种人口统计学、住房和生活方式变量的问卷数据。
任何STH感染的流行率为12.6%。主要土壤传播蠕虫的各自流行率为蛔虫(7.8%)、钩虫(2.8%)和鞭虫(2.2%)。本研究结果表明,STH流行率在年龄、性别、厕所使用情况、家庭规模和指甲修剪方面存在差异。
本研究结果表明,安博地区STH阳性检出率较低。此外,大家庭规模、不修剪指甲和缺乏改良厕所被确定为STH感染的易感因素。所有参与和未参与本研究的学童应每年接受两次治疗,直至流行率降至公共卫生重要性水平以下。
