Gender-based violence (GBV) is a global epidemic associated with increased HIV exposure. We assessed the prevalence and correlates of HIV acquisition via forced sex among women living with HIV (WLWH) in Canada. Baseline questionnaire data were analyzed for WLWH (≥16 years) with data on self-reported mode of HIV acquisition, enrolled in a community-based cohort study in British Columbia, Ontario, and Québec. We assessed forced sex (childhood, adulthood) as a self-reported mode of HIV acquisition. Of 1,330 participants, the median age was 42 (interquartile range [IQR] = 35-50) years; 23.5% were Indigenous, 26.3% African/Caribbean/Black, 43% White, and 7.2% of Other ethnicities. Forced sex was the third dominant mode of HIV transmission at 16.5% (n = 219; vs. 51.6% consensual sex, 19.7% sharing needles, 5.3% blood transfusion, 3.8% perinatal, 1.3% contaminated needles, 0.4% other, 1.6% do not know/prefer not to answer). In multivariable analyses, significant correlates of HIV acquisition from forced versus consensual sex included legal status as a landed immigrant (adjusted odds ratio [aOR] = 1.99; 95% confidence interval [CI] = [1.12, 3.54]) or refugee (aOR = 3.62; 95% CI = [1.63, 8.04]) versus Canadian citizen; African/Caribbean/Black ethnicity versus Caucasian (aOR = 2.49; 95% CI = [1.43, 4.35]), posttraumatic stress disorder symptoms (aOR = 3.00; 95% CI = [1.68, 5.38]), histories of group home residence (aOR = 2.40; 95% CI = [1.10, 5.23]), foster care (aOR = 2.18; 95% CI = [1.10, 4.34]), and having one child relative to having three or more children (aOR = 0.52; 95% CI = [0.31, 0.89]). GBV must be considered a distinct HIV risk factor; forced sex is a significant underrecognized risk factor and mode of women's HIV acquistion. Public health reporting systems can separate consensual and forced sex in reporting modes of HIV acquisition. Practitioners can engage in screening practices to meet client needs.
