Pediculosis de la cabeza en escolares de Ciudad Bolívar, estado Bolívar, Venezuela

Abstract

Abstract: Between April and July 2013, a cross sectional study was conducted to determine the prevalence of headlice in children aged 6-15 years enrolled in four schools in Ciudad Bolívar, Bolivar State, Venezuela. The parasitological diagnosis was made by direct observation of eggs, nymphs and/ or adults on the scalp and/or hair. After signing the informed consent, we filled a clinical and epidemiologic record to each participant. 697 children (40.3%) of the 1730 school enrollment were evaluated, determining a prevalence of 25.1% (175/697). Girls were significantly more infected (42.4%) (OR: 9.35 p 0.05), but the group of 8-11 years was predominant (70.3%). Factors associated with a higher prevalence of headlice were female (OR: 9.35 po,o5) aunque predominó el grupo de 8-11 años. Los factores asociados a una mayor prevalencia de pediculosis de la cabeza fueron: el género femenino (OR: 9,35 p<0,05), haber padecido anteriormente la enfermedad (OR: 5,76 p<0,05) y tener el pelo largo (OR: 7,12 p<0,05) y sucio (OR: 2,20 p<0,05). En conclusión, aunque la prevalencia de pediculosis de la cabeza fue relativamente baja (25,1%), se verifica que esta parasitosis sigue siendo un problema médico importante en escolares de Ciudad Bolívar.
