A latent class analysis of substance use and culture among gay, bisexual and other men who have sex with men.

Latent class analysis was used to examine how patterns of substance use represent the social, economic and identity-related experiences of this population. Participants were sexually active gay and bisexual men (including other men who have sex with men), aged ≥ 16 years, living in Metro Vancouver (n = 774). LCA indicators included all substances used in the past six months self-reported by more than 30 men. Model selection was made with consideration to model parsimony, interpretability and optimisation of statistical criteria. Multinomial regression identified factors associated with class membership. A six-class solution was identified representing: ‘assorted drug use’ (4.5%); ‘club drug use’ (9.5%); ‘street drug use’ (12.1%); ‘sex drug use’ (11.4%); ‘conventional drug use’ (i.e. tobacco, alcohol, marijuana; 25.9%); and ‘limited drug use’ (36.7%). Factors associated with class membership included age, sexual orientation, annual income, occupation, income from drug sales, housing stability, group sex event participation, gay bars/clubs attendance, sensation seeking and escape motivation. These results highlight the need for programmes and policies that seek to lessen social disparities and account for social distinctions among this population.enAttribution-NonCommercial-NoDerivatives 4.0 InternationalPostprintSchool of Public Health and Social PolicyDepartment of Anthropology
