- OBJECTIVES
In Korea, as in most countries, there will be a sharp increase in the number of dementia patients in the near future. However basic data on dementia prevalence, which is important in defining epidemiologic characteristics and in implementing preventive strategy, are limited. This study was conducted to estimate the prevalence rate of dementia in the urban elderly aged 65 or older in Kwangmyung, Korea. METHODS: A two phase design was used for case finding and case identification. In phase I, a representative sample aged 65 or older was selected and interviewed by door-to-door survey with a Korean version of the Mini-Mental State Examination (K-MMSE). In phase II, Of the 946 subjects interviewed in phase I, 356 elderly were randomly selected disproportionately according to K-MMSE score. Of these elderly, 223 (61.5%) underwent standardized clinical evaluations, including psychiatric interview, neurological examination, and neuropsychological assessment. Dementia was diagnosed by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. The diagnosis of Alzheimer's disease (AD) was made by National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association(NINCDS-ADRDA) criteria and vascular dementia (VD) by DSM-IV. RESULTS: The overall weighted prevalence rate of all dementia among Kwangmyung residents aged 65 or older was 12.8%(age-adjusted rate: 13.0%, 95% Confidence Interval[CI]: 10.6-15.3%). Women had much higher prevalence rate than men even when age was controlled(15.9%[95% CI 12.6-19.2%] vs 7.5%[95% CI 4.6-10.4%]). The rates of dementia were 5.2%, 12.2%, 17.0%, and 34.3% for the age groups of 65-69, 70-74, 75-79 and 80 and over, respectively. The rate of AD appeared to be slightly higher than that of VD(5.2% vs 4.8%), though not statistically significant. Most of the cases(69%) were mild dementia according to CDR(<1) in these subjects. CONCLUSIONS: These results showed that the prevalence rate of dementia among urban elderly in Korea appears to be higher than those of other Asian countries.

- Urinary cadmium is used as a sensitive indicator for internal Cd dose, and increased excretion of N-acetyl-beta-D-glucosaminidase(NAG), beta(2)microglobulin(MG) and total protein are useful indices for renal dysfunction by chronic exposure to Cd. The target group was 184 inhabitant(82 men and 102 women) in an abandoned mine area known as exposure to low level Cd. The control group was took 160 individuals(64 men and 96 women) in Cd not-exposed area. Urinary Cd concentration was significantly higher in the target group than the control. The geometric mean of urinary Cd for male was 2.56ng/l, 2.80ng/g creatinine and 2.50ng/S.G. in the target group and 1.19ng/l, 1.36ng/g creatinine and 1.17ng/S.G. in the control. For female 2.69ng/l, 3.94ng/g creatinine and 2.63ng/S.G. in the target group and 1.27ng/l, 1.97ng/g creatinine and 1.25ng/S.G. in the control, respectively. In addition, urinary Cd of the target group had affected by the period of residence and dietary habit for the rice and the vegetables from the target area. These findings suggest the chronic exposure to Cd of the target population. Mean excretion of urinary NAG, beta(2)MG and total protein were not significant between two groups. In the target group, urinary NAG activity and total protein were significantly correlated with urinary Cd, but beta(2)MG was not related. Urinary excretion of NAG, beta(2)MG and total protein were significantly increased in 10 than in <2 of urinary Cd level. In 2~10 group of urinary Cd level, the excretion of NAG significantly increased while not showed for beta(2)MG. In present study, urinary excretion of NAG was relatively sensitive than beta(2)MG in chronic exposure population to low level Cd.
