This study aimed to identify the prevalence of NAFLD in patients with BD and investigate the risk factors of NAFLD.Patients and Methods: A total of 678 patients with BD were included in the study. Clinical data were obtained from the hospital’s electronic health record system. Data included fasting blood glucose, alanine aminotransferase, triglycerides, aspartate aminotransferase, high-density lipoprotein cholesterol (HDL), alkaline phosphatase, total cholesterol, glutamine transpeptidase, uric acid, apolipoprotein A1, apolipoprotein B, and liver ultrasound findings.Results: The prevalence of NAFLD was 43.66% in patients with BD. Significant differences in body mass index (BMI), mean age, diabetes prevalence, course of BD, fasting blood glucose, alanine aminotransferase, HDL, alkaline phosphatase, triglycerides, aspartate aminotransferase, uric acid, glutamine transpeptidase, apolipoprotein B, total cholesterol, and apolipoprotein A1 were seen between the groups (all P< 0.01). Male sex, age, BMI, course of BD, alanine aminotransferase, fasting blood glucose, aspartate aminotransferase, diabetes, glutamine transpeptidase, total cholesterol, alkaline phosphatase, triglycerides, uric acid, apolipoprotein B, HDL, and apolipoprotein A1 levels were correlated with NAFLD (all P< 0.05). In patients with BD, diabetes (OR=6.412, 95% CI=1.049− 39.21), BMI (OR=1.398, 95% CI=1.306− 1.497), triglycerides (OR=1.456, 95% CI=1.036− 2.045), and apolipoprotein A1 (OR=0.272, 95% CI=0.110− 0.672) were risk factors for NAFLD (all P< 0.05).Conclusion: Risk factors for NAFLD in patients with BD include diabetes, BMI, course of BD, and a low level of apolipoprotein A1. A proactive approach to disease management, such as appropriate physical activity and adoption of a healthy diet, and regular monitoring of changes in patient markers should be adopted to reduce the prevalence of NAFLD.Keywords: China, comorbidity, Psychiatry
