Prevalence of cerebral palsy in Turkish children between the ages of 2 and 16 years.
The aim of this cross-sectional study was to determine the prevalence of cerebral palsy (CP) among children in Turkey between the ages of 2 and 16 years. Samples were selected from cities, towns, districts, and villages using the cluster sampling method; 41,861 children were selected. Data was collected by parental interview and physical examination. One hundred and eighty-six children were identified with CP. The prevalence of CP was determined as 4.4 per 1,000 live births and included postnatally acquired CP. Origin of CP was classified as prenatal in 49 (26.6%), perinatal/neonatal in 34 (18.5%), postnatal in 11 (5.9%), and unclassifiable in 90 participants (48.9%; data was unobtainable for two individuals). Type of CP was diplegia in 39.8% of children, hemiplegia in 28%, tetraplegia in 19.9%, ataxia in 5.9%, and dyskinetic in 6.4%. Prenatal factors were seen more frequently in the groups with a high socioeconomic status while perinatal factors were encountered more often in those with a low socioeconomic status (p<0.05). Place of residence and sex had no significant effect on the prevalence of CP (p>0.05). This cross-sectional study shows that the prevalence of CP in Turkey is higher than that in developed countries but the aetiology is probably similar. Although the high prevalence of CP in Turkey could originate from an increased level of obstetric and neonatal problems, the lack of a possible aetiological factor in approximately half the children suggests that the high level might also be due to other factors, such as genetic disorders.
