Abstract

This study was conducted to elucidate the related factors with the decreased physical function in the community- dwelling elderly in Chuncheon. We used data obtained from Hallym Aging Study(HAS) from January to May in 2007. The participants were 505 elderly aged 65 years or over after excluding those who didn't complete physical function test and aged < 65. The measurement of physical function was based on the "Health Aging and Body Composition Study Physical Performance Battery(H-ABC PPB)" that included semi-tandem stance, tandem stance, single leg stance, 6m general walk, 6m narrow walk, and chair stand test. And we also included grip strength test. Overall physical function based on H-ABC PPB decreased with age in both men and women. Smoking appeared to increase the risk of decreased function of chair stand in women (adjusted OR=3.8, 95% CI=1.2-12.6). Regular exercise was found to reduce the risk of decreased physical function in both men(Balance OR=0.5, 95% CI=0.2-1.0; Usual walk OR=0.4, 95% CI=0.2- 0.9) and women(Balance OR=0.4, 95% CI=0.2-1.0; Usual walk OR=0.3, 95% CI=0.1- 0.9); Narrow walk OR=0.2, 95% CI=0.1-0.8). Higher level of education seemed to be associated with higher functional performance. It needs further researches on the effect of education on the physical function of the elderly in this population.

PURPOSE
This study was performed to develop risk prediction model for cardiovascular disease using intima-media thickness (IMT) of carotid artery among the community dwelling elderly.
METHODS
Follow-up survey was conducted in 2007 to measure the IMT of carotid artery, which is known as a preclinical marker of atherosclerotic change, among participants at the baseline survey of Hallym Aging Study (HAS) in 2004. They were categorized into two groups; increased IMT > or = 0.9 mm and normal IMT < 0.9 mm. To evaluate which factors are independently related with the increased IMT, multiple logistic regression analysis was done. Based on the regression coefficients of these factors weighed by the magnitude of the effect estimates, we calculated the risk scores for increased IMT for every participants. ROC curve was plotted for the each cutoff point of risk scores and its fitness was tested using Area Under the Curve (AUC). Finally, we calculated risk ratios for the increased IMT according to the level of risk based on the risk scores.
RESULTS
Several factors were found as related factors for the increased IMT in the multiple logistic regression: age (beta=0.15), cholesterol (beta=0.01), insulin (beta=0.13), and pulse pressure (beta=0.90) for men, and age (beta=0.08), family history of diabetes mellitus (beta=0.94) and stroke (beta=0.79), alcohol drinking (beta=0.39), and high cholesterol (beta=0.77) for women. We assigned the weighed value for each factors. The average risk scores were 14.48 (range 9.69-18.76) for men and 4.59 (range 2.41-7.48) for women. The Area Under the Curve (AUC) were 0.77 for men and 0.71 for women. We also observed the higher risk of increased IMT as the risk scores increased.
CONCLUSION
Based on the results, we expect to predict the level of the risk for the increased IMT, which is preclinical marker for atherosclerotic change, among the elderly.; Summary
