Según información del “American Journal of Respiratory and Critical Care Medicine”, el estudio se llevo a cabo durante 11 años e incluyó a más de 2.800 adultos. Los investigadores compararon la incidencia del asma y síntomas respiratorios a la exposición pasiva al humo en el útero y durante la infancia, reportada por los mismos participantes del estudio. Los autores consideran que la exposición total combinada con el tabaquismo pasivo durante la infancia podría representar cerca del 25% de los casos de asma de adultos entre los participantes del estudio. Eso sugiere que casi una cuarta parte de casos de asma en adultos podrían prevenirse si los niños no estuvieran expuestos al humo pasivo de padres y otras personas en el hogar, concluyeron.
Los investigadores señalan que este es el primer estudio que muestra que la exposición al humo pasivo en el útero o durante la infancia causa una vulnerabilidad perdurable para el asma o síntomas respiratorios.
