Characteristics associated with having no prior Hepatitis B virus infection among participants screened for the SiVET studies in Kenya and Uganda (2014–2017)
HBV infection
REGRESSION, NAIROBI
We present the results of the logistic regression analyses of having no prior HBV infection among participants who had complete data on HBsAg and HBcAb-Total (n = 1265).In the unadjusted analysis, participants from Kampala (AOR 2.19; 95% CI 1.64–2.94) and Nairobi (AOR 2.79; 95% CI 2.06–3.81) had significantly higher odds of having no prior HBV infection than participants from the two fishing communities around Entebbe. Having a formal occupation was associated with lower odds of having no prior HBV infection than having an informal high-risk occupation (AOR 0.44; 95% CI 0.29–0.67).In the adjusted analysis, when compared to the youngest age group (≤24 years), the odds of having no prior HBV infection were lower among those aged 25–29 years (AOR 0.51; 95%CI 0.36–0.71) and those aged ≥30 years (AOR 0.35; 95% CI 0.25–0.49). Taking participants from Entebbe with informal high-risk occupations as the reference group, participants had a higher likelihood of having no prior HBV infection if they had informal high-risk jobs and were either from Kampala (AOR 2.21; 95% CI 1.41–3.47) or Nairobi (AOR 2.61; 95% CI 1.72–4.00). Also, among Entebbe participants, there was no association between occupation and the likelihood of having no prior HBV infection (
