Prevalence of pediculosis capitis in children from a rural school in Yucatan, Mexico / 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 percent) and this was associated with both lower income (OR 9.9, 95 percent CI 2.15-45.79, p = 0.003) and a higher frequency of hair washing (OR 8, 95 percent CI 1.58-50, p = 0.012). Intersectoral control programs that take into account the socioeconomic differences of children should be implemented.

RESUMO

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 por cento) apresentaram pediculose. A infestação de piolho foi associada com baixa renda (OR 9.9, 95 por cento CI 2.15-45.79, p = 0.003) e maior frequência de lavagem de cabelos (OR 8, 95 por cento 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.
