Abstract

Background: Human pediculosis is an important factor in assessing the level of public health and personal hygiene. Objectives: The aim of this study was to determine the prevalence of pediculosis (head lice infestation) and the factors affecting the rate of infestation. Methods: A cross-sectional study design was used to conduct the study among the Kormanj tribes in North Khorasan province, northeastern Iran. The study was conducted between April to June of 2016. A total of 867 subjects were selected randomly and an interviewer questionnaire was used on each subject to sort for information on demographic profile and factors associated with rate of infestation to pediculosis. Results: Data was statistically analyzed using Excel 2015 and SPSS Statistics 24 software; t-test and Chi-square tests were used to check for any statistical significant association between the variables. A total of 28 cases (3.2%) were found to be infected with head lice, 10 cases (35.7%) out of the 3.2% prevalence had a history of infestation with head lice in the past while the remaining 18 cases (64.3%) had no history of lice infestation in the past. Significant statistical association was observed between the sex and history of head lice infestation (P < 0.05). There was no significant difference between lice infestation and the level of education of the subjects, family size, sharing of personal belongings, length of hair, hair posture, showering frequency, the frequency of brushing hair, and permanent scarf coverings at home. Conclusions: The pediculosis is one of the main public health problems in nomadic tribes such as Kormanj tribes in North Khorasan province. It seems that improvement of personal health conditions in females and also appropriate treatment in previous infestations for nomadic tribes could significantly reduce the prevalence of human head lice infestation. © 2018, Author(s).
