The Frequency of Head Lice, Health Practices and Its Associated Factors in Primary Schools in Khorramshahr, Iran

Head louse infestation caused by Pediculus capitis is a health issue that frequently affects school aged children. This infestation has harmful social and mental effects and is related to the populations with low social-hygiene status..
The current study aimed to evaluate the prevalence of head lice and determine its related factors..
The children were selected by stratified systematic cluster random sampling of primary schools in 2008 - 2009 in Khorramshahr, Iran. A total of 750 pupils were screened from ten primary schools from the first to fifth grades. Students were examined for live lice or nits by experienced educators. The data were compared by Chi-square analysis. Also, P value less than 0.05 was considered significant..
According to the obtained results, Pediculosis spp. prevalence was 2% among male and female students of Khorramshahr primary schools; it was 2.6% in females and 1.5% in males. There was a significant relationship between using common tools and equipment (comb, towel, hat, headscarf and bed). There was a significant relationship between bathing and infestation. There was no statistically significant difference between infestation and mothers’ education and occupation. But, the difference between fathers’ education and occupation and pupils’ infestation rate was significant..
The overall infestation rate in the present study is probably one of the lowest infestation rates in Iran and in the region. It appears necessary to examine pupils by trained persons for early detection of infestation..
