Abstract
Intimate partner violence (IPV) is associated with pre-exposure prophylaxis (PrEP) acceptability among US women, but whether IPV influences other steps along the PrEP care continuum remains unclear. This study estimated the causal effects of IPV on the early stages of the PrEP care continuum using doubly robust (DR) estimation (statistical method allowing causal inference in non-randomized studies). Data were collected (2017–2018) from a cohort study of 124 US women without and 94 women with IPV experiences in the past 6 months (N = 218). Of the 218 women, 12.4% were worried about getting HIV, 22.9% knew of PrEP, 32.1% intended to use PrEP, and 40.4% preferred an “invisible” PrEP modality. IPV predicts HIV-related worry (DR estimate = 0.139, SE = 0.049, p = 0.004). IPV causes women to be more concerned about contracting HIV. Women experiencing IPV are worried about HIV, but this population may need trauma-informed approaches to help facilitate their PrEP interest and intentions.
Resumen
La violencia por parte de la pareja (IPV) está asociada con la aceptabilidad de la profilaxis previa a la exposición (PrEP) entre las mujeres de EE. UU., Pero no está claro si la IPV influye en otros pasos a lo largo del proceso de atención de la PrEP. Este estudio estimó los efectos causales de la IPV en las primeras etapas del continuo de atención de PrEP utilizando una estimación doblemente robusta (DR) (método estadístico que permite la inferencia causal en estudios no aleatorios). Los datos se recopilaron (2017-18) de un estudio de cohorte de 124 mujeres estadounidenses sin experiencia y 94 mujeres con experiencias de IPV en los últimos seis meses (N = 218). De las 218 mujeres, 12.4% estaban preocupadas por contraer el VIH, 22.9% conocían PrEP, 32.1% intentaban usar PrEP y 40.4% preferían una modalidad PrEP “invisible”. La IPV predice la preocupación relacionada con el VIH (DR estimado = 0.139, SE = 0.049, p = 0.004). La IPV hace que las mujeres estén más preocupadas por contraer el VIH. Las mujeres que tienen IPV están preocupadas por el VIH, pero esta población puede necesitar enfoques informados sobre el trauma para ayudar a facilitar sus intereses e intenciones de PrEP.
