Complex dynamics between internalized HIV stigma, depression, and anxiety with panic among people with HIV

Previous studies suggest that internalized HIV stigma (IHS) results in HIV viral nonsuppression via directly increasing depression, which then reduces adherence leading to nonsuppression; however, the dynamics between IHS and mental health are likely more complex. We sought to better understand IHS-mental health dynamics using data from a longitudinal clinical cohort of people with HIV (PWH) receiving healthcare across 10 US primary care clinics.

Among 8,506 PWH who had ≥2 timepoints in which IHS, depression, and anxiety were measured, we examined changes over time in both two-state (i.e., impact of IHS on depression or anxiety and vice versa) and four-state combinations of depression-IHS (i.e., no depression or IHS, depression/no IHS, no depression/IHS, both depression/IHS) and anxiety-IHS. Transition probabilities between states and factors influencing transitions were identified using multistate Markov models.

The impact of IHS on the transition rates of mental health measures (i.e., depression, anxiety) and vice versa were almost the same, suggesting that each influences the other. Over 50% of PWH remained in the same IHS-depression or IHS-anxiety state. PWH with IHS had almost twice the rate of transitioning from no depression/anxiety to having depression/anxiety compared to PWH without IHS; with similar results for the depression or anxiety with no IHS to reporting IHS transition.

We demonstrate that IHS and mental health dynamics are more complex than previously suspected and that the associations are bidirectional, which has implications for both future analyses and optimal management of these conditions among PWH.
