High Interest in a Long-Acting Injectable Formulation of Pre-Exposure Prophylaxis for HIV in Young Men Who Have Sex with Men in NYC: A P18 Cohort Substudy
Bibliographic record
Abstract
OBJECTIVE: In the context of continued high rates of condomless anal intercourse and HIV-1 infection, young men who have sex with men (YMSM) need additional effective and desirable HIV prevention tools. This study reports on the willingness of a racially-ethnically diverse cohort of YMSM to use a new biomedical prevention approach, a long-acting injectable pre-exposure prophylaxis (LAI-PrEP) agent. METHODS: A cross-sectional study conducted between June-August 2013 recruited participants from an ongoing cohort study of YMSM in NYC. Participants included 197 YMSM, of whom 72.6% (n = 143) identified as men of color. Two outcomes were measured through computer-assisted self-interviews: 1) willingness to use long-acting injectable PrEP and 2) preference for route of administration of PrEP. In addition, concerns about perceived impacts of PrEP on health and risk behavior, access to health services, and stigma were investigated. RESULTS: Over 80% (n = 159/197, p<0.001) of participants stated they would be willing to use LAI-PrEP. With regards to preference for mode of delivery 79.2% (n = 156/197, p<0.001) stated they would prefer an injection administered every three months over a daily pill or neither one. CONCLUSIONS: This study is the first to explore acceptability of LAI-PrEP in the US. A significant majority of participants expressed willingness to use LAI and the majority preferred LAI-PrEP. LAI-PrEP holds great promise in that it could circumvent the adherence challenges associated with daily dosing, especially if nested within appropriate psycho-behavioral support. Medical providers whose patients include YMSM at high risk for HIV infection should note the positive attitudes toward PrEP, and specifically LAI-PrEP.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
