HIV-Related Stigma Among Black Mothers in Two North American and One African Cities.

HIV-related stigma is a negative attitude or behaviour towards persons living with HIV, and is detrimental to effective care, management, and treatment of HIV. Using a revised 10-item stigma scale, we compared levels of HIV-related stigma and its correlates among Black women living with HIV in Ottawa, Canada, and Miami, FL, USA, with those in Port Harcourt, Nigeria. HIV-related stigma scores were calculated, with a maximum score of 10 and averaged 4.71 in Ottawa, 5.06 in Miami, and 3.78 in Port Harcourt. No significant difference in HIV-related stigma scores between Ottawa and Miami. HIV-related stigma was significantly (p < 0.05) higher among women in the North American cities compared with women in the African city. Hierarchical linear modelling shows that psychosocial variables contributed to variations in HIV-related stigma in Ottawa (22.3%), Miami (36.3%), and Port Harcourt (14.1%). At p < 0.05, discrimination was a significant predictor of increased HIV-related stigma in Ottawa (ß = 0.077), Miami (ß = 0.092), and Port Harcourt (ß = 0.068). Functional social support had a significant diminishing effect on HIV-related stigma in Miami (ß = - 0.108) and Port Harcourt (ß = - 0.035). Tackling HIV-related sigma requires sociocultural considerations within specific regional and national contexts.
