Abstract

Background and aims: Viral hepatitis is one of the top five reasons people die from infections all around the world. The present study aimed to assess the epidemiological features of hepatitis B and hepatitis C infections in Kohgiluyeh and Boyer-Ahmad province.

Methods: The data were obtained via the census method from the registered hepatitis B and hepatitis C data in the reportable disease care system of Yasuj University of Medical Sciences. The collected data are the result of serological tests. The χ 2 test was used to evaluate the important risk factors for hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. The joinpoint regression was performed to investigate the trend of HBV and HCV in recent years.

Results: Here, 1270 cases of hepatitis B and C were identified and reported in Kohgiluyeh and Boyer-Ahmad province from 2008 to 2021. The median age of patients was 38 (interquartile range: 31-51), varying significantly according to the type of hepatitis. The most common hepatitis in males was hepatitis C and in females, hepatitis B. Regarding the place of residence, HBV and HCV were both more prevalent in urban areas. The age group of 25-34 years has the highest prevalence of HBV and HCV. According to the joinpoint regression analysis, there is a decrease in the 14-year trend of incidence rate due to total hepatitis B and C: the annual percent change was -5.2% (95% confidence interval [CI]: -8.4 to -1.9, p = 0.005) for hepatitis B and -0.2% (95% CI: -10.7 to 11.6, p = 0.976) for hepatitis C.

Conclusion: This study shows the incidence rate of hepatitis B has been decreasing during the years of study but this trend has been stable for hepatitis C. Also, the highest number of cases of hepatitis B and C were reported in the age groups of 25-34 years. Hence, preventive interventions are vital in reducing the burden of these diseases.
