Introduction
Little is known about the current representative depression situation among Chinese older inpatients. The aim of this study is to examine prevalence of depression and associated risk factors among Chinese older inpatients by a large-scale cross-sectional national survey.
Methods
This study is based on baseline survey data from a large-scale cohort study in a representative sample of Chinese older inpatients. The procedure of this study involves physical examination and face-to-face questionnaire interviews. Depression was assessed based on the Geriatric Depression Scale 15. Mixed-effect Poisson regression model was used to examine the relationship between depression and covariates by controlling the cluster effect of hospital wards.
Results
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.
Conclusions
There was a high prevalence of depression among Chinese older inpatients. Demographic characteristics, physical and mental conditions indicators have strong effect on prevalence and strength of depression. Therefore, it is essential to assess depression and perform comprehensive measures to improve physical and mental conditions in order to manage depressive symptoms in older inpatients.
