Head lice infestation caused by Pediculus humanus var capitis (Pediculus capitis) is a worldwide public health concern that affects mostly school aged children. This descriptive, analytical study was carried out in 2008 to determine the prevalence of pediculosis capitis and some risk factors among primary-school pupils in Bahar, Hamadan Province, Iran.
We selected 900 pupils (50% girls and 50% boys) from 18 primary schools by multistage, systematic random sampling. Their hair was examined for head louse infestation. The results and demographic information recorded in the questionnaire and then were analyzed by SPSS software.
Twelve students (1.3%) were infected with lice, 10 (2.2%) girls and 2 (0.44%) boys. The rate of infection was 0.66% in urban and 1.66% in rural areas. The results showed significant variations in head lice infestation, and factors such as sex, level of parent education and habitat (P 0.05).
The prevalence of pediculosis was less than average percentages observed in other students inside and outside Iran. We recommend that the parents and teachers should receive training about the danger of infection and its distribution in family and school in order to prevent it.
人头虱（头虱）引起的头虱感染是一个全球公共卫生问题，主要影响学龄儿童。这项描述性分析研究于2008年开展，以确定伊朗哈马丹省巴哈尔地区小学生头虱感染的患病率及一些风险因素。
我们通过多阶段系统随机抽样从18所小学选取了900名学生（50%为女生，50%为男生）。检查他们的头发是否有头虱感染。将结果和调查问卷中记录的人口统计学信息录入，然后用SPSS软件进行分析。
12名学生（1.3%）感染了虱子，其中10名（2.2%）女生和2名（0.44%）男生。城市感染率为0.66%，农村为1.66%。结果显示头虱感染存在显著差异，且与性别、家长教育程度和居住环境等因素有关（P<0.05）。
头虱感染的患病率低于在伊朗国内外其他学生中观察到的平均百分比。我们建议家长和教师应接受关于感染风险及其在家庭和学校中的传播的培训，以预防头虱感染。
