The prevalence of mild mental retardation in 6 15 year old children


, : The prevalence of mild mental retardation in 6 15 year old children. Revue Roumaine de Medecine Neurologie et Psychiatrie 24(3): 161-166

The investigation was performed in a sample representative at country level. A questionnaire followed by testing with Raven's progressive matrices of the children suspect to be mentally backward were used. Prevalence of mild mental retardation in the 10-15-year-old group was 3.08% with no significant differences. In the 6-9-year old, it was only about 1.60% (due probably to underascertainment).
