Abstract
Pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF)/emtricitabine is 99% effective in preventing HIV when taken daily. Young men/transgender women of color who have sex with men are the most at risk to become infected with HIV, with the lowest PrEP adherence. We investigated the association of depression, anxiety, and history of childhood trauma with PrEP adherence. PrEP adherence was measured by urine TDF testing. Patients were evaluated for depression (Patient Health Questionnaire-9 [PHQ-9]), anxiety (Generalized Anxiety Disorder-7 [GAD-7]), and history of childhood trauma (Adverse Childhood Experiences [ACEs]). Urine TDF levels were compared across scores on each screening tool using a Student’s t-test. A p-value of ≤ 0.05 was considered significant. Thirty-one subjects (mean age: 21.7 years, SD: 2.8) were enrolled between 3/2015 and 7/2016. Lower PrEP adherence was associated with a GAD-7 score diagnostic for generalized anxiety (80.7% versus 92.7%, p = 0.04) and a high ACE score (4+) (84.5% versus 95.7%, p = 0.05). A PHQ-9 score diagnostic for major depression was not associated with PrEP adherence. The presence of generalized anxiety and a history of childhood trauma, but not major depression, were associated with decreased PrEP adherence. The benefits of mental health interventions and trauma-informed care in PrEP programs should be considered in larger studies to potentially increase adherence.
