Interpretation, communication, and mechanisms of associations between injectable contraception and HIV risk
Obstetrics and Gynaecology (East Africa)
Data from the VOICE study1 showing greater HIV-1 acquisition among women who use depot medroxyprogersterone acetate (DMPA) than injectable norethisterone (NET-EN) contraception elicited comment suggesting that use of DMPA be limited.2 The fundamental uncertainty, which has not been addressed by the VOICE data or recent meta-analyses of other observational data cited in the commentary,3,4 is whether DMPA increases susceptibility to HIV, or whether women at increased risk of HIV are more likely to use DMPA.
