Prevalence of Psychological Distress in Type ii Diabetes in China

Abstract

Type 2 diabetes mellitus (T2DM) patients are commonly comorbid with psychological distress, such as depressive symptoms, anxiety symptoms, and diabetes distress, which cause great health and economic burden. However, the estimated prevalence of this psychological comorbidity is quite different between studies. Our aim is to estimate the pooled prevalence of depressive symptoms, anxiety symptoms, and diabetes distress in T2DM patients in China. Two Chinese academic databases (China National Knowledge Infrastructure and Wanfang) and two English academic databases (PubMed and Embase) were systematically searched for studies with information on the prevalence of depressive symptoms, anxiety symptoms, and diabetes distress among Chinese T2DM patients published from inception to April 20, 2018. Random-effects meta-analysis was performed to estimate the pooled prevalence. Data were extracted from 80 cross-sectional studies involving 31874 Chinese T2DM patients. The pooled prevalence of depressive symptoms, anxiety symptoms, and diabetes distress were 37.8% (95% confidence interval [CI] 34.6–41.0), 28.9% (95% CI 21.0–36.9), and 50.5% (95% CI 42.4–58.7), respectively. Patients aged 60 years or older have higher prevalence than patients aged <60 years for depressive symptoms, anxiety symptoms, or diabetes distress. Much attention should be paid to the psychological conditions of Chinese T2DM patients, especially for those patients aged 60 years or older in T2DM management.
