What is Engage Montreal?

  • The objective of the Engage study is to provide an up-to-date portrait of various aspects related to the sexual health of gay, bisexual and other men who have sex with men (gbMSM). This information aims to support prevention interventions.
  • Participants are residents of Vancouver, Toronto or Montréal, and have been sexually active with other men in the past 6 months. Montréal’s public health department is doing the Montréal component of the study in collaboration with a team of representatives from community organizations, universities and public health.
  • Engage is the most recent study of gbMSM undertaken in Québec that combines observations collected through a questionnaire and biological samples. The last study of this nature dates back to 2008.  
  • Recruiting a representative sample of a specific population always presents a challenge. The Engage study used an adapted form of chain referral sampling: participants were recruited through people who have already participated in the study. All participants are invited to continue their participation by returning at 6-month intervals to complete a questionnaire and provide biological samples. 

Engage Montreal data collection ended in January 2023 and participant visits are no longer taking place.
