Preference between precoital and daily use of duet® and buffergel in zimbabwe preferencia entre uso precoito y diario de duet® y buffergel en zimbabue

Duet® is a microbicide-delivery system and cervical barrier for use daily or precoitally. We conducted a crossover study among 80 Zimbabwean women to explore factors associated with use-regimen preference. Women were assigned in random order to 14 days of precoital and 14 days of daily Duet and BufferGel use. About 51 % of women preferred precoital use, 39 % preferred daily use, and 10 % liked both equally. Overall product adherence during sex was similar for both use-regimens. In multivariable analysis, diaphragm experience was associated with preference for precoital use (AOR 2.80, 95 % CI 1.01-7.76). Reasons for preferring precoital use included use only when needed, cleanliness, and discomfort with daily use. Daily use preference included convenience, discreetness, and being prepared for "sex-on-demand." Different personal and life circumstances may result in varying use-regimen preferences. Methods that can accommodate both coitally-related and daily use may be advantageous by providing more choice to users. © Springer Science+Business Media, LLC 2012.
