Head lice infestation in schoolchildren and related factors in Mafraq governorate, Jordan

Little is known about the effect of socioeconomic status on the infestation by head lice in schoolchildren in Jordan.

A cross-sectional school-based study was conducted from December 2009 to February 2010. A list of all primary schools in Mafraq governorate was obtained (394 primary schools). Eight primary schools were randomly selected (four male schools and four female schools). Data were collected by five well-trained nurses. Hair was examined for head lice as well as for eggs/nits. Analysis of data was conducted by using SPSS software version 16. The chi-square test was used to assess statistical significance of subgroup differences in the prevalence of infestation, and multivariate logistic regression was used to control for potential confounding.

Out of 1550 primary schoolchildren screened, 412 (26.6%) were infected with lice, 163 (19.6%) boys and 249 (34.7%) girls. The results showed significant variations in head lice infestation by factors such as gender, age, and socioeconomic variables (family income, father's education, mother's education, number of rooms, number of siblings younger than 15 years, frequency of hair washing per week, and bathing per week). There was no significant variation in lice infestation with parents' occupation (P > 0.05).

Socioeconomic status is a major factor influencing the occurrence of pediculosis capitis among schoolchildren in both sexes. Improving standards of living and personal hygiene might significantly reduce pediculosis capitis in schoolchildren in Jordan.
