[Study on the prevalence of depression among cancer patients and its influencing factors in Shanghai].
OBJECTIVE
To determine the prevalence of depression among cancer patients and its influencing factors.


METHODS
We investigated 7967 cancer patients who lived in communities with cluster sampling based on 'Shanghai Cancer Patient Database'. They were investigated through questionnaires and completed the Zung Self-rating Scale. 6694 questionnaires were identified as 'qualified'. We calculated the prevalence of depression and determined the factors with logistic regression model.


RESULTS
The prevalence rate of depression among cancer patients in communities was 24.74% (95% CI: 23.71% - 25.79%). Results from multi-factor analysis showed that duration since diagnosis, stages at diagnosis, metastasis, therapeutics, KPS scores, and pain VAS scores were the important factors.


CONCLUSIONS
Early detection, improving the curative effect and providing community health services could reduce the prevalence of depression.
