Objetivo Describir las características ambientales de los niños de 0 a 24 meses que acuden al servicio de urgencias pediátricas del hospital General de Cataluña y el hospital Parc Taulí (ambos hospitales de la provincia de Barcelona) y que son diagnosticados de bronquiolitis por virus respiratorio sincitial durante el periodo comprendido entre noviembre de 2010 y febrero de 2011. Método Se ha realizado un estudio observacional descriptivo transversal, con una muestra de 97 niños con edades comprendidas entre los 0 y los 24 meses, siendo indiferente el sexo, diagnosticados de bronquiolitis con virus respiratorio sincitial positivo. Los datos se obtuvieron mediante un cuestionario no validado que se cumplimentó con la información que facilitaron los padres y con datos de la historia clínica. Resultados La media de edad de los participantes fue de 3,8 meses; el 53,6% (52) pertenecía al sexo masculino. El 57,8% (56) tenía hermanos en edad escolar. El 80,4% (78) de las madres no fumó durante el embarazo y el 32% (31) tenía un entorno fumador en su domicilio. La media de personas que cohabitaban en el domicilió fue de 3,8 personas; en el 49,5% (48) cohabitaban 4 personas y en el 34% (33) 3. Conclusiones Los factores de riesgo más prevalentes en este estudio han sido, en primer lugar, tener hermanos en edad escolar, seguido del sexo masculino y, en tercer lugar, el entorno fumador. Encontramos una gran mayoría de niños encuestados que tienen factores de riesgo asociados, ya que solo un 8,2% no presentaba ningún factor de riesgo (AU)
