Characteristics of somatic symptoms among Chinese patients diagnosed with major depressive episode.

ABSTRACT

PURPOSE: This study aimed to describe the clinical features of somatic symptoms among Chinese patients diagnosed with major depressive episode (MDE). METHODS: A total of 213 inpatients with MDE from two mental health hospitals were recruited and investigated using the Somatic Symptom Inventory (SSI), Hamilton rating scale for depression, Hamilton rating scale for anxiety, and a demographic questionnaire. RESULTS: The participants included 142 patients with unipolar depression and 71 patients with bipolar depression. The mean SSI score of all participants was 49.30 (SD = 14.80). "Feeling fatigued, weak, or tired all over" was found to be the most common somatic symptom (61.0% reported moderate levels or above), followed by "feeling of being not in as good physical health as most of your friends" (56.3%), and "feeling weak in parts of the body" (49.3%). "Headache" and "soreness in muscles" were common painful symptoms. Both patients with unipolar and bipolar depression had similar somatic symptoms, including painful and non-painful ones. The somatic symptoms of all participants were closely correlated with the severity of depression and anxiety (P < 0.01). Patients with anxiety, older age, low education, and negative life events in the last year had more somatic symptoms. CONCLUSIONS: Inpatients with MDE of somatic symptoms are common, which were significantly correlated with the severity of depression and anxiety. Further efforts should focus on early recognition and integrated care model management of patients based on their characteristics to improve their quality of life and treatment outcomes.
