Objective: Depression symptom was common among the oldest-old people and there is no study to observe the association of depression with habits of smoking, alcohol consumption, tea consumption and exercise among very old people. The present was conducted to analysis the association of depression with these habits. Design, Setting, Participants: A cross-sectional study conducted in Dujiangyan Sichuan China, 692 unrelated Chinese nonagenarians and centenarians (67.34% women, mean age 93.50 years) resident in Dujiangyan. Measurements: A brief 23-item geriatrics depression scale Chinese-edition (GDS-CD) test was used to diagnose depression and these habits were collected. Results: In the whole population, compared subjects with depression, participates those without depression had significantly higher prevalence of exercise habit. However, in women, there was no significant difference in prevalence of these habits between subjects with and without depression except the habit of former alcohol consumption. After adjustment for age, gender, educational levels, religion habits and cognitive function and BP levels and BMI, we found that current habit of exercise had a significant odds ratio (OR=0.31 95% CI (0.11, 0.83)) for depression in oldest old men. Conclusions: Among Chinese Nonagenarians/Centenarians, among habits (current and former) of smoking, alcohol consumption, tea consumption and exercise, there seems to be significant association of depression only with exercise and former habits of alcohol consumption. Former habit of alcohol consumption in women might be associated with a greater risk of depression, but exercise habit in men might be associated with a lower risk of depression.
