A mixed method analysis of differential reasons for condom use and non-use among gay, bisexual, and other men who have sex with men

Abstract

We sought to examine how condom use was differentially reasoned by gay, bisexual and other men who have sex with other men (GBM) in Ontario, Canada. Data were derived from a community-based study of GBM who completed an anonymous online questionnaire in 2014. Participants qualitatively described reasons a condom was used or not at their most recent anal sex event. Qualitative responses were thematically coded non-exclusively and associations with event-level and individual-level factors were determined quantitatively using manual backward stepwise multivariable logistic regression. Among 1,830 participants, 1,460 (79.8%) reported a recent anal sex event, during which 884 (60.6%) used condoms. Reasons for condom use included protection/safety (82.4%), norms (30.5%), and combination prevention (6.2%). Reasons for non-use were intentional (43.1%), trust (27.6%), unintentional (25.7%), and other strategies (19.6%). Event-level substance use was associated with all non-use reasons: e.g., more likely to be unintentional, less likely to be trust. Condom non-use with online-met partners was associated with more intentional and unintentional reasons and less trust reasons. Non-white and bisexual GBM were less likely to explain condom use as a norm. Participant-partner HIV status was an important predictor across most condom use and non-use reasons: e.g., sero-different partnerships were more likely to reason condom use as combination prevention and condom non-use as trust, unknown status partnerships were more likely to reason non-use as unintentional. Condom use among GBM is a multi-faceted practice, especially with increasing antiretroviral-based HIV prevention. Future interventions must adapt to changing GBM (sub-)cultures with targeted, differentiated, culturally-appropriate, and sustained interventions.
