Prevalence of child disability in Saudi Arabia

A large scale prevalence study for child disability of those under 15 years was conducted in a representative Saudi population with accurate demographic records. A 83% response rate in children of six to 15 years (1280 out of 1544 children registered) of age and a 100% response rate in children under five years (all the 1151 registered) was achieved. Thirty one children had severe impairment and 322 had minor impairment. This accounted for 3.76 per 1000 total population with major impairment and 42.8 per 1000 total for minor impairment.
