La encuesta, realizada a 5.764 niños de 57 escuelas públicas de Filadelfia, muestra que uno de cada cuatro respondió saber que tenía asma, y uno de cada tres presentaba síntomas sugerentes de la enfermedad.
En comparación, las estadísticas nacionales indican que uno de cada 10 niños estadounidenses están afectados por asma, cifra que queda bastante por debajo de lo que revelan estudios realizados en ciudades como Nueva York y otras áreas urbanas.
