Prevalence of hepatitis B virus surface antigen, associated risk factors, and liver enzyme abnormalities among individuals with diabetes in Aksum town public hospitals, Tigray, northern Ethiopia.

Abstract

Introduction: hepatitis is an inflammatory disease of the liver; it is a major threat to public health and is more prevalent worldwide. Hepatitis B virus (HBV) is the leading cause of cirrhosis and hepatocellular carcinoma (HCC) with increasing mortality and burden of disease particularly in Asia and sub-Saharan Africa. Therefore, this study intended to assess the prevalence of HBsAg, associated risk factors, and liver enzyme abnormalities among individuals with diabetes mellitus (DM) in Aksum town public hospitals, Tigray, northern Ethiopia.

Methods: a hospital-based cross-sectional study was conducted among 359 randomly selected individuals with diabetes mellitus in public hospitals of Aksum town from February 10 to May 10, 2021. A pre-tested structured questionnaire was used to collect the data. Data was entered into Epi-Data version 3.1 and analysis was made using the statistical software SPSS version 21 for Windows. Bivariate and multivariate Logistic regression model was applied to show association between the dependent and independent variables; P <0.05 and 95% confidence interval was considered for statistical significance.

Results: in this study, 359 individuals with DM were included with a mean age (mean ± SD) of 46.44 ±16.58 years. The percentage of female participants was 44.3% (159/359). The prevalence of HBsAg among individuals with diabetes mellitus in Aksum town public hospitals was 12.8% (95% CI:8.9-17.0%). The associated risk factors were being employed [AOR:13.38, 95% CI 2.79-64.11; p<0.05], having history of multiple sexual partner [AOR:3.49, 95% CI 1.33-9.12; p<0.05], having history of body incision or piercing [AOR:3.80, 95% CI 1.12-12.90; p<0.05], liver enzyme abnormalities [AOR:6.90, 95% CI 2.17-21.94; p<0.005], and being single and widowed in marital status [AOR:4.42, 95% CI1.62-12.07; p<0.05].

Conclusion: based on the HBsAg positivity, the prevalence of HBV among individuals with diabetes mellitus in this study area was high, as compared to the national findings. Therefore, integrated efforts should be made at the community and health facility level to raise awareness of the associated risk factors, and reduce the spread of HBV; targeted screening of HBV among people with diabetes is also important to minimize liver abnormalities.
