Abstract

Depressive symptoms are common in first episode schizophrenia. However, the prevalence and its associations of comorbid depressive symptoms with clinical variables are less well characterized in Chinese Han patients with schizophrenia. In this cross-sectional study, we recruited 240 first-episode and drug naïve (FEDN) inpatients with schizophrenia. All patients were rated on the 17-item Hamilton Depression Rating Scale (HAMD-17) to measure depressive symptoms, and also on the Positive and Negative Syndrome Scale (PANSS) for psychopathology. Our results showed that 131 patients had a total score of 8 or more points on HAMD-17, making the prevalence of comorbid depressive symptoms 54.6%. Fewer women (48.1%, 62 of 129) than men (62.2%, 69 of 111) had comorbid depressive symptoms. Compared to those patients without depressive symptoms, those with depressive symptoms showed higher PANSS total, general psychopathology, cognitive factor and negative symptom scores (all p < 0.05). Further stepwise multiple logistic regression analysis indicated that the PANSS general psychopathology, the PANSS total score and gender (all p < 0.05) remained significantly associated with depressive symptoms. In addition, correlation analysis showed significant correlations between HAMD total score and the following parameters: the PANSS general psychopathology, total score, and cognitive factor (Bonferroni corrected p's < 0.05). Our results suggest that depressive symptoms occur with high prevalence in FEND schizophrenia in a Chinese Han population, and show association with general psychopathology, as well as with cognitive impairment.
