Abstract

Pediculus humanus capitis is a worldwide public health concern that affects mostly primary school age children. The objective of present study was to determine the prevalence of pediculosis infestation in primary schoolchildren, in relation to socioeconomic status of the family and hygienic practices in the home. The sample size of the study was 750 pupils in 25 primary schools in Paveh city who were selected by multistage, systematic random sampling. A total of 60 (8%) students of 5 grades were infested with different rates of infestation. A standard questionnaire recorded information of students about demographic features that were filled by the students. Children aged 8-9 years showed the highest prevalence rates (41.7%) and pupils aged ≥ 12 years had the lowest rate of infestation (3.3%). There were significant relationship between head louse infestation and parents' education, pupils' age and father's job (p<0.05). The prevalence of head lice was higher than those observed in many studies in Iran. Pediculosis was found to be more prevalent in children of parents with lower level of education and socioeconomic status. There is a need for increasing awareness and education of teachers and parents in health education to prevent pediculosis. (Boshra Vahabi, Ahmad Vahabi, Alireza Gharib, Mahnaz Sayyadi, Sirvan Sayyad.
