Abstract

Abstract: Background: Men who have sex with men (MSM) on antiretroviral therapy (ART) are at risk for multimorbidity as life expectancy increases. Simulation models can project population sizes and age distributions to assist with health policy planning. Methods: We populated the CEPAC-US model with CDC data to project the HIV epidemic among MSM in the United States. The PEARL model was predominantly informed by NA-ACCORD data (2009–2017). We compared projected population sizes and age distributions of MSM receiving ART (2021–2031) and investigated how parameters and assumptions affected results. Results: We projected an aging and increasing population of MSM on ART: CEPAC-US, mean age 48.6 (SD 13.7) years in 2021 versus 53.9 (SD 15.0) years in 2031; PEARL, 46.7 (SD 13.2) years versus 49.2 (SD 14.6) years. We projected 548 800 MSM on ART (147 020 ≥ 65 years) in 2031 (CEPAC-US) and 599 410 (113 400 ≥ 65 years) (PEARL). Compared with PEARL, CEPAC-US projected a smaller population of MSM on ART by 2031 and a slower increase in population size, driven by higher estimates of disengagement in care and mortality. Conclusions: Findings from two structurally distinct microsimulation models suggest that the MSM population receiving ART in the United States will increase and age over the next decade. Subgroup-specific data regarding engagement in care and mortality can improve projections and inform health care policy planning. Abstract : Two structurally distinct simulation models project that the population of MSM receiving ART in the United States will continue to grow and age over the next decade, emphasizing the need for health policy planning promoting healthy aging among people with HIV.
