BACKGROUND
Intestinal parasites are still a serious public health problem in the world, especially in developing countries. This study aimed to assess the prevalence of intestinal protozoa infections and associated risk factors among schoolchildren in Sanandaj City, Iran.
METHODS
This cross-sectional study involving 400 schoolchildren was carried out in 2015. Each student was selected using systematic random sampling method. Questionnaire and observation were used to identify possible risk factors. Fresh stool samples were observed using formal-ether concentration method.
RESULTS
Five species of intestinal protozoa were identified with an overall prevalence of 42.3%. No cases of helminthes infection were detected. The predominant protozoa were (21.3%) and (4.5%). Overall, 143 (35.9%) had single infections and 26 (6.4%) were infected with more than one intestinal protozoa, in which 23 (5.9%) had double intestinal protozoa infections and 3 (0.5%) had triple infections. A significant relationship was observed between intestinal protozoa infection with economic status, water resources for drinking uses, and the methods of washing vegetables (<0.05).
CONCLUSION
Education programs on students and their families should be implemented for the prevention and control of protozoa infections in the study area.
背景
肠道寄生虫仍是全球尤其是发展中国家严重的公共卫生问题。本研究旨在评估伊朗萨南达杰市学童肠道原生动物感染的患病率及相关危险因素。
方法
2015年对400名学童开展了这项横断面研究。采用系统随机抽样方法选取每名学生。通过问卷调查和观察来确定可能的危险因素。采用甲醛-乙醚浓缩法观察新鲜粪便样本。
结果
鉴定出5种肠道原生动物，总体患病率为42.3%。未检测到蠕虫感染病例。主要的原生动物是（21.3%）和（4.5%）。总体而言，143名（35.9%）有单一感染，26名（6.4%）感染了不止一种肠道原生动物，其中23名（5.9%）有双重肠道原生动物感染，3名（0.5%）有三重感染。观察到肠道原生动物感染与经济状况、饮用水源以及蔬菜清洗方式之间存在显著关联（<0.05）。
结论
应针对研究区域内的学生及其家庭实施教育项目，以预防和控制原生动物感染。
