Background: The World Health Organization recommends HBV–HIV-coinfected individuals start antiretroviral therapy containing tenofovir. Here we describe first-line tenofovir use and treatment outcomes in coinfected patients in Asia. Methods: HBV surface antigen positive patients enrolled in the TREAT Asia HIV Observational Database who started first-line antiretroviral therapy were included. Logistic regression adjusted for period of treatment initiation was used to determine factors associated with tenofovir use. Generalized estimating equations were used to evaluate factors associated with alanine transaminase levels and CD4+ T-cell count on treatment. Results: There were 548 eligible patients, of whom 149 (27.2%) started tenofovir. Patients treated in high/highmiddle income countries (odds ratio 4.4 versus low/lowmiddle, 95% CI 2.6, 7.4; P
