Association between HIV/AIDS knowledge and stigma towards people living with HIV/AIDS in Botswana.

In Botswana, an estimated 350 000 people live with HIV/AIDS. HIV/AIDS testing rates are low, suggesting that many other people remain undiagnosed. Stigma related to HIV/AIDS is prevalent and contributes to low testing rates and under-diagnosis of the virus. Identifying factors that contribute to stigma, such as insufficient or inaccurate knowledge of HIV/AIDS, may be critical in increasing early identification and treatment. This cross-sectional study used nationally representative data from the 2013 Botswana AIDS Impact Survey (BAIS) IV to examine the relationship between HIV/AIDS knowledge and stigmatising attitudes toward people living with HIV/AIDS (PLWHA). The mean (standard error) for stigma towards PLWHA score and HIV/AIDS knowledge score were 0.99 (0.02) and 5.90 (0.03) respectively. HIV/AIDS knowledge score and stigma towards PLWHA score were strongly positively correlated r (4,4045) = 0.415, p < 0.001). After adjusting for potential confounders, HIV/AIDS knowledge score significantly predicted stigma towards PLWHA score [coefficient β (95% CI)] [-0.25 (-0.29, -0.20), p < 0.001]. These findings imply that programmes and interventions that increase HIV/AIDS knowledge may reduce the pervasive apprehension, blame, and stigmatising attitude held towards PLWHA in Botswana.
