Of all 9727 respondents, the mean age of all respondents was 72.4±5.7 years, from 65 to 97. The average GDS score was 2 (
1,
4). The prevalence rate of depression was 16.7% (95%CI: 15.8–17.4%) among older inpatients. The prevalence rates were 14.6% for males and 19.5% for females respectively. After controlling the cluster effect of hospital wards, age, gender, ADL score, educational level, BMI, frail, marriage, falls, alcohol drinking, cognitive function, living conditions, vision, hearing, sleep and defecation function were associated with depression. Emaciation (OR=1.176, 95%CI: 1.107–1.249), frail (OR=1.562, 95%CI: 1.489–1.639), divorced or widowed (OR=1.083 95%CI: 1.017–1.153), living in the bungalow (OR=1.075, 95%CI: 1.023–1.130), falls (OR=1.078, 95%CI: 1.030–1.128), cognitive function (OR=1.142, 95%CI: 1.091–1.195), vision dysfunction (OR=1.125, 95%CI: 1.076–1.177), hearing dysfunction (OR=1.061, 95%CI: 1.011–1.113), sleep dysfunction (OR=1.237, 95%CI: 1.194–1.282), defecation dysfunction (OR=1.160, 95%CI: 1.103–1.221) could increase prevalence risk of depression.
