Abstract

Recent work shows that variation in adult hearing function is related both to social class of origin and current social class. This study examines how much of this relationship after adjustment for childhood hearing impairment is explicable by occupational noise, current smoking, and alcohol consumption. A cohort of 9023 persons born in the UK during one week in 1958 was followed periodically, and hearing threshold levels (HTLs) were measured at 1 kHz and 4 kHz at age 45 years. Most (71% and 68%, at 1 kHz and 4 kHz respectively) of the relation to social class of origin of adult HTLs remains after adjustment for these other factors. For the relation to current social class, corresponding values are 64% and 44% (though varying by gender). The magnitude of social class effect is comparable to that of occupational noise. Susceptibility to hearing impairment is likely to be appreciably determined in early childhood.

Sumario

Trabajos recientes muestran que la variación en la función auditiva del adulto está relacionada tanto con la clase social de origen como con la clase social actual. Este estudio examina qué tanto de esta relación es explicada por el ruido ocupacional, el tabaquismo y el consumo de alcohol vigente, después de ajustes por la hipoacusia adquirida en la infancia. Se siguió una cohorte de 9023 personas nacidas en el RU durante una semana en 1958 y se les midieron los umbrales auditivos (HTLs) a 1 y 4kHz a los 45 años de edad. La mayoría (71% y 68%, a 1kHz y a 4kHz, respectivamente) de los HTLs de los adultos permanecen en relación con la clase social de origen después del ajuste de estos otros factores. Para la relación con la clase social actual, los valores correspondientes son 64% y 44% (aunque varían según el género). La magnitud del efecto de la clase social es comparable con aquella del ruido ocupacional. Al parecer la susceptibilidad a presentar hipoacusia está apreciablemente determinada en la infancia temprana.
