OBJECTIVE: To explore the prevalence and associated factors of anxiety and depression symptoms in hospitalized Chinese patients with coronary artery disease (CAD). METHODS: From June 2007 to May 2009, 1083 hospitalized patients with confirmed coronary artery disease were recruited in this study. The ZUNG Self-rating Anxiety Scale (SAS) and the ZUNG Self-rating Depression Scale (SDS) were used for the psychological assessment. Economic status, living condition and the environment of both living and working places were evaluated by epidemiological questionnaires. RESULTS: The prevalence of pure anxiety, pure depression symptoms and the combination of anxiety and depression symptoms were 7.9%, 28.3% and 14.3% respectively. Incidence of anxiety and depression symptoms was significantly higher in female patients compared with in male patients (P = 0.003, 0.012 respectively) and in aged patients than in middle-aged patients (P = 0.001). The elderly, less than 9 years of education and poor sleep quality increased the risk of anxiety symptom with ORs of 1.63 (95%CI: 1.21 - 2.21), 1.54 (95%CI: 1.15 - 2.07) and 1.62 (95%CI: 1.34 - 1.96), respectively, while workplace noise, history of chronic disease and poor sleep quality increased the risk of depression symptom with ORs of 1.52 (95%CI: 1.18 - 1.98), 1.36 (95%CI: 1.06 - 1.75) and 1.27 (95%CI: 1.08 - 1.50), respectively. Female (OR = 1.91, 95%CI: 1.22-2.98), aged patient (OR = 1.84, 95%CI: 1.23 - 2.76), workplace noise (OR = 1.61, 95%CI: 1.07 - 2.42), history of chronic disease (OR = 1.84, 95%CI: 1.24 - 2.71) and poor sleep quality (OR = 1.73, 95%CI: 1.35 - 2.21) were significantly correlated with the combined incidence of anxiety and depression symptoms. CONCLUSION: Around half of the Chinese hospitalized CAD patients were complicated with various degrees of anxiety and/or depression symptoms. Female and aged patients were at higher risk for anxiety and depression symptoms. Sleep quality, workplace noise, years of education and history of chronic disease were independent risk factors for anxiety or depression symptoms.
