Intestinal helminthic infections are among the most important global socioeconomic and health problems. This study aimed to estimate the frequency of intestinal parasites in 366 children aged 2 to 15 years referred to the main pediatric health center of Lorestan Province, Iran.
Microscopic analysis was performed on 366 stool samples. We applied direct smear, scotch tape, and formol-ether methods. Moreover, a questionnaire was filled in by parents or guardians of the children.
The results showed that 36 children (9.8%) were infected with at least one or more intestinal parasites. The most prevalent parasites were (6.8%), (1.9%), and (0.55%), in the order of their appearance. Statistical analysis showed that several risk factors were significantly associated with the prevalence intestinal helminthic parasites, including male sex (OR = 2.9; 95% CI: 1.2-6.2; p < 0.05), residing in rural regions (OR = 4.2; 95% CI: 2.1-10.6; p < 0.001), no handwashing habit before eating (OR = 5.2; 95% CI: 2.2-12.5; p < 0.001), and consuming raw or unwashed vegetables and fruits (OR = 4.8; 95% CI: 2.3-11.2; p < 0.001).
The present study showed a high overall frequency of intestinal helminthic infections among the children in Lorestan province, Iran. The results of the risk factor analysis suggest that improving environmental hygiene and health education would be important for effective control of intestinal parasitic infections.
肠道蠕虫感染是全球最重要的社会经济和健康问题之一。本研究旨在估计转诊至伊朗洛雷斯坦省主要儿科健康中心的366名2至15岁儿童肠道寄生虫的感染率。
对366份粪便样本进行显微镜分析。我们采用了直接涂片法、透明胶带法和甲醛乙醚法。此外，由儿童的父母或监护人填写一份问卷。
结果显示，36名儿童（9.8%）感染了至少一种或多种肠道寄生虫。最常见的寄生虫依次为（6.8%）、（1.9%）和（0.55%）。统计分析表明，几个风险因素与肠道蠕虫寄生虫的感染率显著相关，包括男性（比值比[OR]=2.9；95%置信区间[CI]：1.2 - 6.2；p<0.05）、居住在农村地区（OR=4.2；95%CI：2.1 - 10.6；p<0.001）、饭前没有洗手习惯（OR=5.2；95%CI：2.2 - 12.5；p<0.001）以及食用生的或未清洗的蔬菜和水果（OR=4.8；95%CI：2.3 - 11.2；p<0.001）。
本研究表明，伊朗洛雷斯坦省儿童肠道蠕虫感染的总体感染率较高。风险因素分析结果表明，改善环境卫生和健康教育对有效控制肠道寄生虫感染至关重要。
