The odds ratios (OR) for depressive symptoms were significantly higher in elderly without housemate [OR=1.30, 95% confidence interval (CI)=1.11-1.53], without contact of living children (OR=1.76, 95% CI=1.03-2.99), lower social activity (OR=2.00, 95% CI=1.71-2.35) and without contact of friends (OR=1.47, 95% CI=1.30-1.67). And impaired activity of daily living (ADL) (ADL : OR=1.61, 95% CI=1.18-2.20, instrumental activities of daily living : OR=1.68, 95% CI=1.36-2.06) and cognitive impairment (OR=1.21, 95% CI=1.07-1.38) were also associated the risk of depressive symptoms.
