The extent of HBV treatment adherence, associated facilitators, and barriers in South Sudan is not established. This study aimed to explore the predictors of medication non-adherence among HBV patients attending a public health facility in, South Sudan.Methods: We conducted a facility-based cross-sectional study of 392 convenience-selected patients using a pretested interviewer-administered questionnaire premised on the information-motivation-behavioral skills (IMB) adherence model between December 2023 and March 2024. The relationship between medication non-adherence and antecedent variables was ascertained by logistic regression analysis.Results: The sample was predominantly male (64.3%), and the mean age was 31.06 (30.19– 31.93) years, with 28.1% reporting no formal education. The patients demonstrated inadequate HBV information (4.33± 1.93), low motivation (8.20± 2.69), and inadequate behavioral skills toward medication adherence (8.45± 2.99), as measured on their respective rating scales. Further, more than two-thirds of the patients (70.2%) were HBV medication non-adherent. Younger age (AOR = 4.74, 95% CI = 2.13– 10.56), being currently unmarried (AOR = 3.25, 95% CI = 1.76– 6.01), unemployment (AOR = 4.19, 95% CI = 1.84– 9.56), and increased behavioral skills (AOR = 1.12, 95% CI = 1.84– 9.56) significantly influenced medication non-adherence. Lower education (AOR = 0.21, 95% CI = 0.10– 0.46) and information adequacy (AOR = 0.63, 95% CI = 0.53– 0.75) were associated with lower odds of non-adherence.Conclusion: The study highlights key factors influencing the concerning rate of medication non-adherence among HBV patients in South Sudan. While these identified factors may explain the lingering burden of HBV-related complications, targeted interventions addressing demographic, socioeconomic barriers, and HBV-specific education are essential to enhance adherence and improve health outcomes.Keywords: hepatitis B, treatment therapy, medication non-adherence, information adequacy, behavioral skills, South Sudan |
