title: Communication disorders in Nigerian children.
abstract: OBJECTIVE
  Communication disorders have been acknowledged as a major public health issue because they compromise early childhood development, restrict vocational attainment and undermine the economic well being of the society. The aim of this study is to determine the pattern of communication disorders among children in a developing country and the requisite intervention services.
  
  
  METHODS
  This prospective study was conducted in Lagos University Teaching Hospital, Lagos between January 2002 and June 2003 among children aged 6 months to 15 years that presented in the audiology clinic of the hospital with communication disorders. All the patients had neurological, otolaryngological, audiological and speech evaluations.
  
  
  RESULTS
  A total of 184 patients were seen during the period out of whom 136 (74%) were between the ages of 6-47 months. Hearing impairment was documented in 120 (65.2%) children, speech disorders in 56 (30.4%), rhinolalia 2.2% and stuttering 2.2%. Of those with hearing impairment, 70% had delayed speech and language. Among children with speech disorders 78.6% had specific language impairment (SLI). Aetiological factors recorded for the communication disorders were seizures 10.9%, measles 8.7% meningitis 8.7%, birth asphyxia 6.5%, otitis media with effusion (OME) 4.3%, kernicterus 4.3%, congenital deformity 4.3%, ototoxicity 2.2%, cerebral palsy 2.2%, and undetermined causes 47.9%.
  
  
  CONCLUSIONS
  Hearing impairment is the commonest communication disorder. Early detection and appropriate follow up is recommended for all children in their first year of life. The role of parents and caregivers in seeking early help should be strengthened while capacity building for the training of more audiologists and speech therapists should be pursued rapidly.
