Determinants of sexual exposure to HIV in Portuguese and Brazilian adolescents: a path analysis.
Jules Ramon Brito Teixeira, Shirley Veronica Melo Almeida Lima, Anderson Reis de Sousa and 5 others
PMID 36197395WHAT IT FOUND
In adolescent men who have sex with men, challenging sexual practices and ineffective protection methods strongly predicted HIV exposure.
Trusting a partner was associated with using less effective protection, increasing risk. Knowledge of prevention methods did not significantly predict exposure.
Key findings
01Challenging sexual practices and ineffective forms of protection had the strongest direct effects on sexual exposure to HIV.
02Higher partner credibility was associated with greater use of ineffective protection methods, which in turn increased sexual exposure.
03Unawareness of HIV prevention methods did not have a significant total effect on sexual exposure.

What it does not show
The observational design cannot establish causality, only associations. Recruitment via online platforms and dating apps limits generalizability to adolescents without internet access or those who do not use these apps. The study excluded participants under 18, so it does not reflect the experiences of younger adolescents. Self-reported sexual behaviors and exposure may be subject to recall or social desirability bias.
Declared interests
No conflicts of interest were declared in the provided text. The study was approved by ethics committees in Portugal and Brazil.
The easy way to misread this
Do not assume that increasing HIV prevention knowledge alone will reduce sexual exposure in this population. The study found that unawareness of prevention methods was not a significant predictor of exposure, whereas behavioral factors like partner trust and specific sexual practices were. Interventions focused solely on education may miss the relational and behavioral drivers of risk.
