Correlates of Casual Sex Amidst Vulnerability to HIV Among ACB Heterosexual Men in Ottawa and Windsor, Ontario Canada.

Heterosexual exposure is the second highest means of HIV transmission; and African, Caribbean, and Black (ACB) men face greater risks. Black men can reduce the disproportionately high HIV prevalence in their communities by changing their socially misconstrued masculine role. We analysed factors predisposing heterosexual ACB men to risky sexual behaviour, particularly multiple casual sex partnerships in Ottawa and Windsor, Ontario, Canada. We employed quantitative datasets from a broader mixed methods study within hierarchical logistic regression model to determine the association between psychosocial factors and casual sex partnerships. The model controlled for city level clustering effect and sociodemographic factors. Precisely 55.0% (n = 52) of men in Windsor and 70.2% (n = 99) in Ottawa had one or more casual sex partners within the past year. Some of them (Windsor, 32.1% [n = 18], and Ottawa, 34.3% [n = 36]) used condom always. HIV knowledge (OR = 0.80, p < 0.01, CI = 0.67/0.95) and pro-Black community attitudes (OR = 0.72, p < 0.05, CI = 0.56/0.94) decreased the odds of casual sex partnerships, while traditional masculinity scores (OR = 1.21, p < 0.05, CI = 1.01/1.46) increased it. The behavioural factors jointly predicted casual sex more than sociodemographic variables and city of residence. We conclude that heterosexual ACB men are predisposed to casual sex partnerships at differing magnitude across cities, and this may constitute a risk factor for HIV exposure. Hence, propagation of HIV knowledge, community attitudes and reconstruction of masculine ideology among ACB men, with due attention to geopolitical differences in city of residence, are recommended.
