Abstract
PURPOSE
To investigate the prevalence rate of fatty liver disease and its related factors of women in rural area.METHODS Seven hundreds and fifty four adult females (above age 30) at eleven Community Health Centers in Koryung County were recruited from 3 March 2001 to 30 May 2001. Abdominal ultrasonography, height, weight, and blood pressure were measured. A questionnaire interviewing method was used to collect life style data.RESULTS The prevalence of fatty liver disease was 13.4%. By simple analysis, age(p<0.05), diabetes mellitus(p<0.01), salt intake(p<0.05), and obesity (p<0.01) were significantly associated with fatty liver disease. In multiple logistic regression analysis, the risk for fatty liver in above 50 age group was 2.7 (95% CI: 1.25-5.99) times higher than that in 30-49 age group, overweight was 10.3 (95% CI: 5.26-19.99) times higher than normal group, 3.9 times (95% CI: 1.84-8.38) higher in person with diabetes mellitus than those without and the risk of current drinkers was 2.0 times (95% CI: 1.03-3.85) higher than non-drinkers.CONCLUSION Above findings suggested that risk factors significantly related with fatty liver were age, BMI, diabetes mellitus, and drinking in adult women.

Abstract
PURPOSE
This study was conducted to estimate the prevalence of osteoporosis and to identify the related factors of bone mineral density (BMD) in rural postmenopausal women.METHODS Three hundred ninety postmenopausal women in a rural area were examined in 1999 Their BMDs of the lumbar spine (L1-L3) were measured by a quantitative computerized tomography (QCT) and their height and weight were measured.
A questionnaires interviewing method was used to collect risk factor data.
PESULTS: The prevalence of osteoporosis in postmenopausal women of 40-69 years old was 89.2% by reference value of UCSF(University of California, Sanfrancisco), however, changed to 63.1% by that of Korean. From simple analyses, age(p<0.01), duration after menopause (p<0.01), menstrual regularity(p<0.05), delivery frequencies (p<0.01), breast feeding years (p<0.01), alcohol intake(p<0.01), and smoking(p<0.05) were significant risk factors relating to BMD. In multiple linear regression analysis, duration after menopause(p<0.01), menstrual regularity(p<0.05), and breast feeding years (p<0.05) proved to be significant risk factors. However dietary factors and life style were not significantly associated with BMD.CONCLUSIONS The significant risk factors of postmenopausal women in a rural area relating to BMD were duration after menopause, menstrual regularity, and breast feeding duration.

Abstract
OBJECTIVES
To estimate the effects of an oral vitamin supplementation on cognitive function in the elderly, 254 elderly people(experiment group) who were received an oral vitamin supplement for one-year was compared with 292 elderly who were treated as the control group in Koje city during the study period(from February 1997 to March 1998).METHODS The cognitive function was tested by mini-mental state examination Korea(MMSE-K). Multiple regression analysis was done to control other confounding variables such as gender, age, educational level, smoking, alcohol, a past 15-day medical history, satisfaction for living cost, family number, cognitive function of the baseline survey.RESULTS In the baseline survey, the prevalence of cognitive impairment was 31%(mild impairment 12.5% and severe impairment 18.5%). There was a significant difference(0.76) in cognitive change in the elderly between two groups, 0.68 improved in the experiment group and 0.08 worsen in the control group(p<0.01). In multiple regression analysis, the significant variables were an oral vitamin supplementation, a past 15-day medical history, family number, cognitive function of baseline survey(p<0.05). The improvement of cognitive function was observed in those who do not have a past 15-day medical history, have a large family number, and have a low cognitive function of the baseline survey.CONCLUSIONS It appears that an oral vitamin supplementation was effective in improving the cognitive function in the elderly and more effective in the cases with abnormal cognitive function.
