Engage COVID-19 Study

The Engage COVID-19 study seeks to document SARS-COV-2 infection, immunity and related determinants among gay and bisexual men (GBM), and to examine how this population perceives and is impacted by measures to curb the spread of the disease.

We are using a mixed-methods approach (using quantitative questions and qualitative interviews in French and English) to understand how the pandemic is impacting GBM in terms of uptake and implementation of COVID-19 messaging, and the interrelated impacts of the COVID-19 pandemic on sexual behaviours and access to HIV and STI testing, treatment, and prevention (e.g., PrEP), mental health outcomes (e.g., anxiety, depression, and loneliness) and substance use patterns.

The study’s aims can be broken down into biomedical aspects (such as the occurrence of, and exposure to, COVID-19) as well as behavioural and psychosocial ones (including mitigation strategies and mental health outcomes).
