Determinants of health are important drivers of health states, yet there is little work examining their role in the relationship between HIV stigma and health. This study uses moderation analysis to examine how determinants of health affect the relationship between enacted, internalized, and anticipated stigma and mental health. Quantitative data was collected on 337 participants in Ontario, Canada at baseline (t1) between August 2018 and September 2019 and at follow-up (t2) between February 2021 and October 2021. Separate moderation models were created with each determinant of health (age, gender, sexual orientation, ethnicity, geographic region, education, employment, and basic needs) acting as the moderator between types of stigma at t1 and mental health at t2. Age was a significant moderator for the relationship between internalized and enacted stigma at t1 and mental health at t2. Region was a moderator for enacted and anticipated stigma and mental health. Sexual orientation was a moderator for anticipated stigma and mental health. Lastly, having basic needs was a moderator for enacted and anticipated stigma and mental health. Our findings suggest that intervention strategies may be more effective by incorporating supports for these determinants of health in addition to stigma reduction to improve mental health.
