Abstract
A cross-sectional epidemiological study on prevalence of hearing loss was carried out in an age- and Down's syndrome- stratified random sample of 1598 persons drawn from a base population of 9012 persons, representative of the Dutch adult population of intellectual disability (ID) service users. The re-weighted population prevalence is 30.3% (95% confidence interval [CI]: 27.7–33.0%). Subgroup prevalences range from 7.5% (95% confidence interval [CI]: 3.6–13.3) in the subgroup aged 18–30 years with ID by other causes than Down's syndrome, up to 100% (95% CI: 79.4–100%) in adults over 60 years of age with Down's syndrome. Down's syndrome (OR 5.18, 95% CI 3.80–7.07) and age were confirmed to be risk factors. Age-related increase in prevalence in persons with Down's syndrome appears to occur approximately three decades earlier, and in persons with ID by other causes approximately one decade earlier than in the general population.
Sumario
Se realizó un estudio epidemiológico transversal sobre hipoacusia con una muestra aleatoria estratificada por edad, en 1598 personas con síndrome de Down, tomadas de una población base de 9012 personas, representativas de los usuarios de servicios para discapacidad intelectual (ID) de adultos en Holanda. La prevalencia de población reconsiderada es de 30.3% (95% de intervalo de confianza revalorada [CI]: 27.7–33.0%). El rango de prevalencia de los subgrupos varió de 7.5% (95% de intervalo de confianza [CI]: 3.6–13.3) en el subgrupo de 18–30 años con ID por otras causas diferentes al S. de Down, hasta el 100% (95% CI: 79.4–100%) en adultos mayores a 60 años con S. de Down. El S. de Down (OR 5.18, 95% CI 3.80–7.07) y la edad se confirmaron como factores de riesgo. El incremento en la prevalencia relacionado con la edad en personas con S. de Down, parece ocurrir aproximadamente tres décadas más temprano y en personas con ID por otras causas, aproximadamente una década más temprano que en la población general.
