Factors that affect acceptance of HIV microbicides among women

SummaryGlobally, women make up more than half of those infected with HIV. For women in nearly every region around the world, the primary mode of HIV transmission is through heterosexual sex. However, over thirty years into the HIV/AIDS epidemic women still lack sufficient means of protecting themselves against HIV. Vaginal HIV microbicides (VHMs) are a promising new method to prevent HIV infection. VHMs are chemical substances that can destroy HIV, block its entry into or fusion with the target cell or inhibit HIV replication once the virus has entered a target cell. They can be applied through various delivery methods intravaginally. VHMs are designed to be used by women and to that end it is crucial to understand women's preferences for formulation, use and other characteristics in order to determine how to increase adherence and acceptability. Of particular consideration is how relationship dynamics will affect microbicide usage. The purpose of this review is to examine the most recent body of literature regarding male and female perceptions of VHMs to prevent male to female transmission of HIV in order to gain a greater understanding of the factors that affect adherence and acceptability of VHM usage among women. A greater understanding of the factors that affect adherence and acceptance of VHMs will have an impact on the uptake of VHMs, allow nurses and other health care providers to counsel clients more effectively about their use and point to new directions needed on the research and development of future microbicides.
