Abstract
Peruvian men who have sex with men (MSM) and transwomen (TW) could benefit from a rectal microbicide (RM) formulated as a rectal douche to prevent HIV infection. However, little is known about rectal douching practices among Peruvian MSM and TW, information necessary to inform RM douche development and future uptake. Using a self-administered interview, we examined the prevalence of and factors associated with rectal douching among a convenience sample of 415 Peruvian MSM and 68 TW. In the previous 6 months, 18 % of participants reported rectal douching using pre-filled commercial kits or plastic bottles or enema bags filled with water, water/soap or saltwater. Multivariate logistic analysis found that “equally insertive and receptive” or “exclusively/mainly receptive” sex roles were associated with douche use. Rectal douching among Peruvian MSM and TW is similar to reports from other studies and supports the potential uptake of a douche-formulated RM in these populations.
Resumen
Los hombres que tienen sexo con otros hombres (HSH) y las mujeres transgénero (MT) peruanos podrían beneficiarse con microbicidas rectales (MR) formulados como una ducha rectal para prevenir la infección por VIH. Sin embargo, se conoce poco sobre las prácticas de duchas rectales entre HSH y MT en Perú, información necesaria para orientar el desarrollo de MR y su futura aceptación. Utilizando una entrevista auto-administrada, examinamos la prevalencia y los factores asociados con el uso de duchas rectales en una muestra por conveniencia de 415 HSH y 68 MT peruanos. En los seis meses recientes, 18% de los participantes reportaron haber usado duchas rectales comerciales pre-llenados o botellas de plástico o bolsas para enema llenas con agua, agua con jabón, o agua salada. El análisis multivariado encontró que los roles sexuales "igualmente insertivos o receptivos" o "exclusivamente/principalmente receptivos" estaban asociados con el uso de duchas rectales. El uso de duchas rectales entre HSH y MT es similar a lo reportado en otros estudios y da respaldo a la posible aceptación por parte de estas poblaciones de los MR formulados.
