Composite Risk for HIV: A New Approach Towards Integrating Biomedical and Behavioral Strategies in Couples-Based HIV Prevention Research

Abstract

A substantial number of new HIV infections among gay, bisexual, and other men who have sex with men and transgender women occurs in the context of primary partnerships. Given the diversity of risk reduction needs and various approaches available for reducing risk within couples, condomless sex is no longer the gold standard HIV outcome. We present a novel, comprehensive, and flexible Composite Risk for HIV (CR-HIV) approach for integrating evolving biomedical and behavioral HIV prevention strategies into couples-based HIV prevention intervention and survey research. We provide illustrative examples of the utility of the CR-HIV approach based on couples' HIV status.

Keywords: Couples; HIV prevention; Men who have sex with men; Transgender women.
