La información epidemiológica sobre síntomas que afectan órganos y aparatos extra-respiratorios en los niños asmáticos es escasa. El objetivo de este estudio era por consiguiente evaluar qué síntomas extra-respiratorios son asociados con el asma. Dos estudios basados en encuestas se llevaron a cabo en 1.262 estudiantes (651 varones, de 6-14 años; edad media 9,57 años,) en 1992 y en 1.210 estudiantes (639 varones de 6-14 años edad media 9,02 años) en 1998, de dos escuelas de Roma, Italia.
Las encuestas incluyeron preguntas sobre el asma y sus factores de riesgo y los síntomas extra-respiratorios (dolor de cabeza, la inquietud, perturbaciones en el sueño, urticaria, prurito y dolor abdominal). De los encuestados 11.9% (279/2.342) tenían una historia de asma.
El predominio de desórdenes de las vías aéreas superiores e inferiores era similar en los dos estudios. La frecuencia de síntomas no asmáticos, incluido urticaria, prurito, dolor abdominal, dolor de cabeza, alteraciones del sueño e irritabilidad excesiva, también eran notablemente similares en los dos estudios.
