Treatment interruptions and community connectedness among gbMSM living with HIV in Metro Vancouver, Canada

ABSTRACT

HIV treatment interruptions are a major public health concern that demonstrate a lack of engagement in care and is detrimental to the health of people living with HIV. Community connectedness have demonstrated a protective effect for psychosocial health but are not well understood for HIV treatment outcomes. We explored associations between community connectedness and treatment interruptions among gay, bisexual and other men who have sex with men (gbMSM) living with HIV in Vancouver, British Columbia. We analyzed survey data from the Momentum Health Study and identified treatment interruptions through data linkages with the provincial HIV Drug Treatment Program as episodes lasting more than 60 days beyond an expected antiretroviral therapy refill date from February 2012 to July 2019. We built a mixed-effects logistic regression model, adjusting for confounders. Of 213 gbMSM living with HIV, 54 experienced treatment interruption (25.4%) over a median five-year follow-up. Multivariable results found the number gbMSM who spoken to in the past month (aOR = 0.995; 95% CI = 0.991, 1.000 (per 100-unit increase)) and attending a gay community meeting more than once per month (aOR = 0.32; 95% CI = 0.11, 0.89) were associated with lower odds of treatment interruptions. These results highlight the importance of social connections in facilitating effective HIV care.
