1.Clinical epidemiology of mental retardation in Gia Sang precinct, Thai Nguyen province
Journal of Vietnamese Medicine 2001;263(9):26-29
A study on the clinical epidemiology and interview of 8965 persons shown that there were 44 cases of mental retardation such as language and psychomotor retardation and difficulty in learning and working. The mental retardation related significantly with the health of pregnant women (bacterial and viral infection, poor nutrition), complications in labour (premature), obstetric interventions (forceps, suffocation), impacts after birth (meningitis, encephalitis, malnutrition, defects, epilepsy, down)

Background: Mental retardation is a common pathological state in children, accounting for about 1 - 3%. Children with mental retardation should have a life of integrity and proper support. The discovery and assessment the children will help us to orient the education, assistance and early intervention for them at each location. Objectives: This study aimed at determining the prevalence of mental retardation (MR) among children in some quarters and communes of Hue city and the degrees of mental retardation in these children. Subjects and method: Screening by WHO questionnaire \u201cTen Question screen for disability\ufffd?and learning results (if possible) of children from 6 to under 16 years old in 5 quarters (urban) and 2 communes (rural) randomly selected in Hue. Diagnostics and evaluations are based on the criteria of ICD \ufffd?10. Results: The prevalence of MR in this study was 0.94% (95%CI = 0.82 \ufffd?1.07), 1.18% in rural area and 0.84% in urban area; 1.16% among boys and 0.70% among girls. Mild MR accounts for 62.67% moderate: 19.36%, severe: 11.52% and profound: 6.45%. Conclusion: The prevalence was statistically significant higher in rural area than in urban area and in boys than in girls. There were predominant percentages of severe and profound MR.

The purpose of this study was to estimate the prevalence of mental retardation (MR) in Korea. The study population comprised 1,757 third-grade elementary school children residing in a single school district in Suwon, Korea. We conducted the total population survey for 1,537 children who attended one of 5 schools in the district. For the remaining 220 children who did not attend a school in the school district, we found children with MR via inspection of the register list of the disabled. A total of 16 children (7 of the 1,537 children and 9 of the 220 children) were found to have MR, yielding a prevalence of MR of 9.1/1,000. Considering that about 60% of the people with disabilities are registered in Korea, there would be at least 6 unregistered children with MR among the 220 children, so that the prevalence of MR can be estimated at 12.5/1,000 for the Suwon area.

The purposes of this study were to present DNA analysis findings of our case series of fragile X syndrome (FXS) based on methylation-specific polymerase chain reaction (MS-PCR), PCR, and Southern blotting alongside developmental characteristics including psychological profiles and to review the literature on FXS in Korea. The reports of 65 children (male:female, 52:13; age, 6.12+/-4.00 yrs) referred for the diagnosis of FXS over a 26-months period were retrospectively reviewed for the identification of full mutation or premutation of fragile X mental retardation 1 (FMR1). Among the 65 children, there were 4 boys with full mutation, and one boy showed premutation of FMR1, yielding a 6.15% positive rate of FXS. All 4 children with full mutation showed significant developmental delay, cognitive dysfunction, and varying degrees of autistic behaviors. The boys with premutation showed also moderate mental retardation, severe drooling, and behavioral problems as severe as the boys with full mutation. Thirteen articles on FXS in Korea have been published since 1993, and they were reviewed. The positive rate of FXS was in the range of 0.77-8.51%, depending on the study groups and the method of diagnosis. Finally, the population-based prevalence study on FXS in Korea is required in the near future.
