Intimate Partner Violence Influences Women's Engagement in the Early Stages of the HIV Pre-exposure Prophylaxis (PrEP) Care Continuum: Using Doubly Robust Estimation.

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.
