Abstract: Objectives: To analyse the characteristic of somatic symptoms of Chinese diabetic patients comorbided with depression. Method: Totally 137 T2DM inpatients were included. Centre for Epidemiological Studies Depression Scale(CES-D) was used to screening depression symptoms and SSI was used to assess the somatic symptoms with the Chinese version of DDS assessing diabetes related emotional distress. Results: The prevalence of depression was 24.8%. DDS score,SSI score and the number of somatic symptoms in depression group was significantly higher than non-depression group.SSI score was negatively related to education level (r= -0.216, P=0.011), positively related to comorbidity of complicaiton(r=0.225, P=0.008), positively related to age (r=0.191, P=0.025), positively related to the number of complications (r =0.335,P<0.001), positively related to CES-D score (r=0.466, P<0.001) and DDS score (r=0.392, P<0.001). Multiple linear stepwise regression analysis showed that CES-D score, DDS score and the number of complications entered the equation and could explain 39.1% of the variation of SSI score (P<0.001). Conclusion: Chinese diabetic patients complicated with depression tended to have more somatic symptoms. There were overlapping in somatic symptoms of diabetes and somatization symptom of depression. Complaining of increasing somatic symptoms was a clue to identify depression in patients with diabetes.
