Abstract: Objective To explore the outcome of children with mental retardation after 3 years follow-up. Methods The subjects were 237 children with mental retardation, selected from Beijing Municipal Investigation for Children with Disability in 2004. Gesell Developmental Schedule and Wechsler Intelligence Scale for Children were used to estimate the children's intelligence. Results After 3 years, the outcome showed non-mental retarded, 124 subjects (52.32%); mild mental retarded, 46; moderate mental retarded, 32; severe mental retarded, 16; profound mental retardation, 19. The related factors include urban/suburban (B=-0.622), parental knowledge about rehabilitation training (B=-0.470) and score of personal social interaction in Gesell Test(B=-0.040). Conclusion The outcomes of children with mental retardation are different. But some problems still exist even in non-mental retarded children.
