Disparities in Incidence of Human Immunodeficiency Virus Infection Among Black and White Women — United States, 2010–2016

Abstract

This report describes the disparities in human immunodeficiency virus (HIV) infection incidence among black and white women in the USA, during 2010-16, using the population attributable proportion (PAP) disparity measure. Data show that from 2010 to 2016, the estimated incidence of HIV infection among black women and adolescent females decreased from 32.5 to 24.4 per 100000 persons; the rate among white women and adolescent females did not differ in 2016 (1.6 per 100000 persons) compared with that in 2010 (1.6 per 100000 persons) and ranged from 1.4-1.7 per 100000 persons during that time. The PAP disparity measure decreased from 0.75 in 2010 to 0.70 in 2016. This change suggests that if the incidence rates for black women were the same as were those for white women, the annual number of incident cases of HIV infection among black and white women would have been 75% lower in 2010 and 70% lower in 2016. The 7% decrease in the PAP disparity measure from 2010 to 2016 (P=0.15) indicates that the percentage of incident HIV infections attributable to racial disparities between black and white women decreased by about 7% over this period. Thus, in 2016, an estimated 3900 of 4200 (93%) incident HIV infections among black women would not have occurred if rates were the same for black and white women.
