Background: Hepatitis, which refers to liver inflammation, can have various causes, with viral hepatitis being the most common. Objectives: This study aimed to compare demographic and laboratory variables, risk factors, and outcomes between Hepatitis B (HBV) and Hepatitis C (HCV) patients in the Fars hepatitis registry. Methods: In this cross-sectional study, a total of 6,690 eligible patients, consisting of 3,840 (57.4%) with HBV and 2,820 (42.6%) with HCV, were assessed from the database covering the period from 1995 to 2023. Comparisons between HBV and HCV were made using the Chi-square test, Fisher's exact test, or independent sample t-test with SPSS software. Results: The average age of the patients was 52.56 years (standard deviation: 13.24). Significant differences were found between HBV and HCV patients regarding sex, marital status, education level, family history of HBV and HCV, smoking status, drug use, and body mass index (P < 0.001 for all). Hepatitis B patients had a higher prevalence of dental procedures (P < 0.001) and uncertain sexual contacts (P = 0.009), while blood transfusion, intravenous drug use, major thalassemia (P < 0.001 for all), tattoos (P = 0.004), and hemodialysis (P = 0.001) were more common in HCV patients. Hepatitis C patients showed higher levels of liver enzymes (P < 0.001) and total bilirubin (P = 0.002) but lower levels of albumin (P < 0.001) and prothrombin time (P = 0.034) compared to HBV patients. Cirrhosis was also more common in HCV patients (P < 0.001). Conclusions: Our findings highlight different patterns of demographic factors, risk factors, and outcomes between HBV and HCV patients, which could influence their prevention and management strategies.
