Prevalence and distribution characteristics of mental retarded children aged 0-14 in Gansu Province
AIM: To investigate the prevalence and distribution characteristics of vision, audition, limbs and mental retarded children aged 0 -14 in Gansu Province and to assess the prevalence and distribution characteristics of mental retardation ( MR). METHODS: A survey was made from April 1, 2006 to May 31 to May, 31, 2006 in 13958 children aged 0 - 14 in Gansu Province with stratified, multi-stage and cluster sampling method. Intelligence screening and diagnosis were conducted with DDST and standardized Geaell developmental schedule and statistical analysis was performed with SPSS13.0 software. RESULTS: The total incidence rate among the children of 13958 was 8. 96‰ and the countryside incidence rate (9.66‰) was higher than that in the city (4.32‰) in Gansu Province, with significant difference (χ2 =5.17,P<0.05). The incidence in boys was little higher that in girls, but with no significant difference ( χ2 = 1 . 307, P > 0. 05). The incidence rate of the children aged 0 - 8 was higher than that of the children aged 9-14 and the difference was significant (χ2 =5.08,P<0.05). The percentage of mild, moderate, severe and most severe of MR was 55. 20% , 23. 20% , 10.40% and 11.20% respectively. CONCLUSION: In Gansu Province, Priority should be given to the prevention and treatment of mild MR, especially to those in the rural areas. Special education should be strengthened to reduce the prevalence of children with mild mental retardation, thus improving population quality.
