Prevalência de pediculose em crianças de escola rural em Yucatan, Mexico

Abstract

We conducted an analytical cross-sectional survey to estimate the prevalence of and factors associated with active head lice infestation. In total 140 children, aged 6 to 16-years, from a public school in rural Yucatan, Mexico, were examined by wet-combing. A structured questionnaire was used to collect information on individuals and the conditions in the surrounding environment. Head lice infestation was found in 19 out of the 140 children tested (13.6%) and this was associated with both lower income (OR 9.9, 95% CI 2.15-45.79, p = 0.003) and a higher frequency of hair washing (OR 8, 95% CI 1.58-50, p = 0.012). Intersectoral control programs that take into account the socioeconomic differences of children should be implemented.Foi conduzido um estudo numa escola publica de área rural em Yucatan, Mexico com o objetivo de estimar a prevalência de pediculose e fatores de risco associados. Das 140 crianças incluídas 19 (13.6%) apresentaram pediculose. A infestação de piolho foi associada com baixa renda (OR 9.9, 95% CI 2.15-45.79, p = 0.003) e maior frequência de lavagem de cabelos (OR 8, 95% CI 1.58-50, p = 0.012). Programas intersetoriais de controle da pediculose que levam em conta as características socioeconômicas das crianças deveriam ser executados
