Purpose: This research was conducted to examine the successful aging and identify factors influencing successful aging in the Korean elderly. Methods: The subjects were 4,507 elders and data were collected from the 4th Korean Longitudinal Study of Ageing in 2012. The data were analyzed using frequencies, weighted percentage, x 2 test, and logistic regression. Results: The results of this study showed that 19.6% of the participants were categorized to successful aging. The domains of the absence of disease and disability and maintaining physical and mental functioning showed a high rate of achievement, while the domain of active engagement with life showed a low rate of achievement compared to others. Successful aging was influenced by gender, age, subjective economic status, subjective health status, and family support, particularly spouse's support. Conclusion: Intervention programs to increase the prevalence of successful aging are required. Especially programs for strengthening spouse's support and enhancing subjective health status are required.

Purpose:The purpose of this study was to compare the use of health services and health expenditures between non-exercise and exercise groups of diabetic patients and among three groups divided according to exercise intensity. Methods: Data were obtained from the Korean Health Panel Survey of 2011. The participants of this study were 864 diabetic patients who did exercise (walk, moderate exercise, or vigorous exercise) or not. Data were subsequently analyzed using the SPSS 21 Program. Results: The exercise group showed higher percentages of medication compliance, non-smokers, and regular diet than the non-exercise group. The hospitalization percentage, the number of outpatient hospital visits, and health expenditures were higher in the non-exercise group than in the exercise group. There was no difference among the three groups divided according to exercise intensity in the use of health services and health expenditures. Conclusion: These results show that exercise is a way to reduce diabetic patients' use of health services and their health expenditures.
