【Abstract】 AIM: To survey the incidence rate, the borderline rate, the severity and pathogenesis of mental retarded (MR) children in Qinba Mountain areas. METHODS: All the children aged 0 14 in Ningqiang, Zhashui and Ankang areas were divided into three groups by area. The potential MR children were chosen for this study by intelligence screening.
