We examined factors influencing the intention of Black and Hispanic gay and bisexual men aged 18-34 years in Texas to discuss starting long-acting injectable pre-exposure prophylaxis (LAI-PrEP) with healthcare providers. Participants were recruited through geosocial apps and community locations, completed online surveys measuring attitudes, subjective norms, perceived behavioral control (Theory of Planned Behavior), internalized homophobia, medical mistrust, HIV risk, and medical mistrust. Among the final sample ( = 190), 63.5% intended to discuss LAI-PrEP. Poisson regression models indicated that higher attitudinal concerns [adjusted prevalence ratio (aPR): 0.80, 95% confidence interval (CI): 0.70, 0.92;  < 0.01) and higher medical mistrust (aPR: 0.98, 95% CI: 0.97, 0.99;  = 0.01) were linked to lower prevalence of intentions. Seeing a doctor in the past 12 months was associated with higher prevalence of discussing LAI-PrEP (aPR: 1.46, 95% CI: 1.00, 2.13;  = 0.05). Addressing concerns and reducing discrimination are crucial for improving LAI-PrEP uptake in this population.
