This study aims to identify the possible association between parent\u2010reported adverse perinatal conditions and permanent hearing loss, in order to establish service needs within current maternal and child health programmes. Structured questionnaires were administered to 363 parents of deaf children and 309 parents of normal\u2010hearing children in an inner city area of Lagos, Nigeria. The parents were from all social classes.<\/jats:p><jats:p>After a multivariable logistic regression analysis, birth asphyxia [OR 20.45; 95% CI 6.26, 66.85], difficult delivery [OR 8.09; 95% CI 2.76, 23.68], neonatal jaundice [OR 2.45; 95% CI 1.25, 4.79] and neonatal seizures [OR 2.30; 95% CI 1.09, 4.85] were associated with permanent hearing loss. Consanguineous marriages [OR 6.69; 95% CI 2.72, 16.46] and family history of deafness [OR 6.27; 95% CI 2.07, 18.97] also emerged as additional risk factors for permanent hearing loss. In addition, parents of children in state\u2010owned schools for the deaf were significantly more likely to belong to higher social classes compared with normal\u2010hearing children in mainstream state\u2010owned schools.<\/jats:p><jats:p>There is a need to incorporate services for the early detection of permanent hearing loss into current maternal and child healthcare programmes in developing
