Abstract

Permanent childhood hearing impairment is a significant public health issue in the United Kingdom and elsewhere. It has effects on the hearing-impaired individual's linguistic, psychological, educational, and vocational development. Data on prevalence are an essential prerequisite for efficient service planning and development. This paper reports the first study to be undertaken in Cyprus to investigate the prevalence and the age at identification of permanent bilateral (congenital or acquired/late-onset) childhood hearing impairment of 50 dB HL or greater. The study was based upon a case ascertainment approach for children born between 1979 and 1996. Two methods were employed for the data collection: interrogation of case records and questionnaires administered to parents. The results for those years in which most cases are likely to have been identified showed an estimated prevalence of 1.19/1,000 live births (congenital) and 0.40/1,000 live births (acquired/late onset), with a mean identification age of 44.0 months for congenital cases. These findings are discussed with reference to the service development needs in Cyprus.

Sumario

Los trastornos permanentes de la auditión en la niñez constituyen un problema significativo de salud pública en el Reino Unido, así como en otros lugares. Producen efectos sobre el desarrollo lingütstico, psicológico, educativo y vocacional del individuo hipoacúsico. Un prerequisite esencial para establecer una eficiente planificación y desarrollo de servicios, es contar con information sobre prevalencia. Este artículo reporta el primer estudio que se haya llevado a cabo en Chipre, investigando la prevalencia y la edad de identificación de trastornos auditivos permanentes de la infancia (congénitos o adquiridos/de aparición tardia), bilaterales y con 50 dB HL o más de pérdida. El estudio se basó en un enfoque de evaluación de casos para niños nacidos entre 1979 y 1996. Se emplearon dos metodos para la recoleccion de information: revision de expedientes y cuestionarios administrados a los padres. Los resulta-dos en aquellos aiios donde parece haberse llevado a cabo la mayor cantidad de identificaciones muestran una prevalencia estimada de 1.19/1000 nacidos vivos (congénitos) y 0.40/1000 nacidos vivos (adquiridos/ aparicion tardia), con una edad media de identìficacion de 44.0 meses para los casos congénitos. Estos hallaz-gos se discuten con referencia a las necesidades de desarrollar servicios en Chipre.
