PS233. Association between vascular risk and depression in the representative Korean elderly population

s | 85 outcome data (presence or absence of being at work and presence or absence of readmission after discharge) were obtained. Results: A logistic regression analysis revealed that low TAS-20 scores and being unmarried were associated with being at work at 6 months after discharge in the participants. No factor was significantly associated with the presence of readmission in this sample. Conclusions: Our findings suggested that alexithymia might be associated with the 6-month prognosis in patients with major depression treated with pharmacotherapy. Individual traits such as alexithymia should be taken into account when we formulate the strategy to improve the prognosis of patients with major depression. PS233 Association between vascular risk and depression in the representative Korean elderly population Jong-Il Park, Sang-Keun Chung, Tae Won Park, Jong-Chul Yang Chonbuk National University, Republic of Korea Abstract Objective: Mixed results exist regarding the role of vascular risk factors in association with elderly depression. The present study investigated the relationships among major vascular risk factors and elderly depression in a large representative of the elderly population of Korea. Method: We examined the dataset of the Survey of Living Conditions and Welfare Needs of Korean Older Persons, which was conducted by the Korea Institute for Health and Social Affairs (KIHASA) in 2011. Participants (n=10,674) were randomly selected from the elderly aged more than 65 years old. Elderly depression was evaluated by the short-version of geriatric depression scale (SGDS). Multivariate logistic regression was used to investigate the association between major vascular risk factors and elderly depression. Results: The prevalence of elderly depression (SGDS cut off ≥ 8) was 30.3%. Participants with depression were significantly older than those without depression. In chi-square test, among major vascular risk factors, participants who had diabetes, hypertension, stroke, and ischemic heart disease (IHD) had significantly higher depression than those without those risk factors, but not in hyperlipidemia. In multivariate analysis, our results revealed that diabetes (OR = 1.242), hypertension (OR = 1.127), stroke (OR = 2.063), and IHD (OR = 1.688) were significantly associated with elderly depression after controlling for confounding variables. Conclusions: Among major vascular risk factors of elderly depression, proper medical management focusing especially on diabetes, hypertension, stroke, IHD might reduce the impact of depression in elderly population.
