Preexposure prophylaxis initiation and alcohol-related sexual risk among young men who have sex with men.
Article in Health psychology : official journal of the Division of Health Psychology, American Psychological Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveHuman immunodeficiency virus (HIV) infection is a significant public health concern, particularly among young men who have sex with men (YMSM). Preexposure prophylaxis (PrEP) is highly effective in preventing HIV infection. However, PrEP does not protect against other sexually transmitted infections. Previous studies have shown unintended consequences following PrEP initiation, including increased sexual risk behaviors. Problematic alcohol use, to which YMSM are particularly vulnerable, may also play a role in increasing sexual risk. The present study examines the prospective relationship between PrEP initiation and alcohol-related sexual behaviors among YMSM.
methodOne hundred thirty-nine YMSM (
resultsPrEP initiation was modeled at Time 1, Time 2, Time 3, and Time 4. Alcohol-related sexual risk behaviors were measured at Time 1 and Time 4. The trajectory of PrEP initiation was used to predict latent change in alcohol-related sexual behaviors. Consistent with our hypothesis, a combined latent change score and latent trajectory model revealed a positive association between PrEP initiation and alcohol-related sexual behaviors between baseline and 18-month follow-up.
conclusionThese results are consistent with research identifying a potentially high-risk period following PrEP initiation among a vulnerable group (YMSM), with implications for risk assessment and interventions targeting alcohol-related sexual behaviors among YMSM. Findings may aid in reducing adverse sexual outcomes among YMSM who initiate PrEP and ultimately contribute to the minimization of sexual health disparities among YMSM.
