OBJECTIVE Head lice infestation (HLI), caused by Pediculus humanus capitis, is an important public health problem worldwide, especially in primary school children. The aim of this study is to investigate HLI level, related factors, and families' knowledge levels and attitudes about HLI in two primary schools in a relatively low socio-economic region in İstanbul. METHODS A questionnaire on HLI was developed initially and delivered to all children and parents in the school. A total of 340 primary school students, aged between 6-12, were enrolled in the study after the consent of their parents. Their hair were examined for HLI with special combs at their schools, and free anti-lice shampoos were given to parents of positive children. A total of 951 completed questionnaires were received and evaluated with chi-square test using the SPSS® 17.0 program, and the differences of p<0.05 were considered significant. RESULTS Number of boys in the study was slightly higher than the girls (176 vs. 164). HLI was detected in 32 (9.4%) of 340 children; seven had live adult lice on their hair while 25 had only the nits. HLI was obviously more common in girls (16.4%), compared to boys (2.8%). Analysis of 951 questionnaires revealed a statistically significant difference between HLI and infrequent bathing (p<0.05). The differences between HLI and the education levels of parents, income, the number of siblings and in contact with animals were not found to be significant (p>0.05). CONCLUSION HLI is still a common health problem, especially in girls in primary schools. Parents are aware of the relationship between the hygiene and prevention against HLI, but low socio-economic resources seem to be important determinants. Regular combing and training activities in primary schools, in coordination with the local authorities and parents are no doubt useful in reducing the incidence of HLI among the children.
