title: Prevalence of skin disorders in school children in Ibadan, Nigeria.
abstract: Although skin diseases are common in children, there are very few population-based studies in West Africa. Recently, there has been considerable emphasis on hygiene and socio-economic impact on the incidence of allergic disorders in children. We determined the prevalence of skin diseases in a public primary school in Ibadan (southwest Nigeria). A questionnaire for assessing factors associated with the prevalence of diseases was completed, and a complete physical examination was carried out on 1066 students. The study included 529 (49.6%) boys and 537 (50.4%) girls with a mean age of 8.8 +/- 2.5 years. The mean family size of the subjects was 6.7 +/- 2.3 while the mean number of rooms in their homes was 2.6 +/- 1.45. Infectious dermatosis was commonly observed. Of 375 children with a skin lesion, 162 (15.2%) had dermatophytosis, most often tinea capitis, 50 (4.7%) had pityriasis versicolor, and 50 (4.7%) had scabies. Other dermatoses observed included papular urticaria in 35 (3.3%) and angular cheilitis in 27 (2.5%) children. One or more melanocytic nevi were found in 40 (3.8%) children while 138 (12.9%) and 77 (7.25%) had tribal and scarification marks, respectively. Atopic eczema and viral warts were virtually absent. We concluded that fungal infections and scabies were the most common skin diseases in our study population, whereas allergic illnesses were nearly absent.
