This study aimed to identify
sub-groups of men who have sex with men at high risk of HIV infection. Data
from the Swedish MSM2013 survey were analysed with a focus on respondents (n =
714) who reported having had unprotected anal intercourse with male casual
partner(s) in the past 12 months.
Weighted Latent Class Analysis with
covariates and distal outcomes was conducted to identify sub-groups of men
sharing the same sexual practice characteristics. Four latent classes emerged:
experimentals, bottoms, risk-reducers and clubbers.
Experimentals appeared to
differ most from the other classes. They had extensive experience of
barebacking, the use of poppers and fisting. Higher number of casual male sex
partners and reporting having HIV were predictors for belonging to
experimentals.
No evidence for an association between self-rated HIV prevention
knowledge and taking less part in risky practices was found. Hence,
knowledge-intensive interventions may not be the best fit for reducing HIV
transmission.
This diversity of men based on similar sexual practice patterns
should be taken into account when designing future HIV prevention interventions.
