Also known as the Bone Mineral Density Sub-study, VOICE B (MTN-003B) was an observational study in a subset of participants in VOICE designed to explore the potential effects, if any, that daily use of oral ARVs may have on bone health in HIV-negative women, and in particular, pre-menopausal women in Africa. VOICE B involved 518 women from Uganda and Zimbabwe who were assigned to one of the oral tablet regimens (oral tenofovir, oral Truvada or oral placebo) in VOICE. VOICE B found small decreases in bone mineral density among young women with higher adherence to the oral tablet tenofovir, findings that are consistent with previous studies, which resolved after stopping its use.
