Intestinal parasitic infections are considered as one of the main socioeconomic and health problems around the world, mostly in tropical and sub-tropical regions. The present study aimed to evaluate the prevalence of intestinal protozoan parasites in 366 children (2- 15 yr old) admitted to health centers of Lorestan Province, Iran. Microscopic examination was performed on 366 stools using the direct smear and formol-ether techniques as well as trichrome and modified Zeihl-Neelsen staining methods. The results showed that 48 children (13.1%) were infected with at least one or more intestinal parasites, of whom 4 (7.1%) had more than one type of parasite. The most prevalent parasites were Giardia lamblia (5.5%), Blastocystis hominis (3.1%), and Entamoeba coli (1.6%), respectively. The study showed that some risk factors such as gender, living in rural areas and consuming unwashed vegetables and fruits (p<0.001) were significantly related to intestinal protozoan infections. These results can be a catalyst for health providers to pay special attention to intestinal protozoan parasites among children in Lorestan Province, Iran. Moreover, intervention curriculums and teaching of children and environmental hygiene must be taken into consideration to prevent and control intestinal protozoan infections in this area.
肠道寄生虫感染被认为是世界各地主要的社会经济和健康问题之一，在热带和亚热带地区尤为突出。本研究旨在评估伊朗洛雷斯坦省各健康中心收治的366名儿童（2至15岁）肠道原生动物寄生虫的感染率。采用直接涂片法、甲醛乙醚法以及三色染色法和改良齐尔-尼尔森染色法对366份粪便样本进行显微镜检查。结果显示，48名儿童（13.1%）感染了至少一种或多种肠道寄生虫，其中4名（7.1%）感染了不止一种寄生虫。最常见的寄生虫分别是蓝氏贾第鞭毛虫（5.5%）、人芽囊原虫（3.1%）和结肠内阿米巴（1.6%）。研究表明，一些风险因素，如性别、居住在农村地区以及食用未清洗的蔬菜和水果（p<0.001）与肠道原生动物感染显著相关。这些结果可促使卫生保健人员特别关注伊朗洛雷斯坦省儿童中的肠道原生动物寄生虫。此外，必须考虑开展干预课程以及对儿童进行环境卫生教育，以预防和控制该地区的肠道原生动物感染。
