While many women report ever/lifetime AI, fewer women report recent AI

Those that do report recent AI – also report other risks for HIV – suggesting compounded risk

Care needs to be taken in how questions are asked – wording, timeframes, and mode of interviewing (ie ACASI)

Vaginal microbicide trials ARE collecting data on AI – but comparing across trials may be problematic due to different timeframes being used

Great data on AI from women in vaginal microbicide trials forthcoming! Stay tuned…
