Patients were categorized into birth-year cohorts of 1940\u20131959, 1960\u20131979, or 1980\u20131999 and then further dichotomized into pre- and post-1980 birth-year cohorts.

Approximately a third of the participants (30%) identified as men who have sex with men, and 39% reported a history of injection drug use. At cohort entry, the majority had a CD4+ cell count &amp;lt;350\/\u00b5L and a viral load &amp;gt;1000 copies\/mL. The HBV prevalence was 6.7% overall but varied by birth-year cohort: 6.2% for 1940\u20131959, 7.9% for 1960\u20131979, and 2.6% for 1980\u20131999.
