Elmes J, Silhol R, Hess KL, et al. - Given the more efficient transmission of HIV with receptive anal intercourse (RAI) vs receptive vaginal intercourse (RVI), researchers sought to determine its contribution to heterosexually‐acquired HIV infections among at‐risk women in the US. From surveys of 9,152 low‐income heterosexual women living in 20 cities with high rates of HIV conducted in 2010 and 2013 as part of US National HIV Behavioral Surveillance, they retrieved sexual behaviour data for this analysis. Findings revealed high RAI prevalence (overall: 32%, city range: 19‐60%) as well as RAI fraction (overall: 27%, city‐range: 18‐34%), both overall and across cities, and also showed a positive link of these with exchange sex. Disproportionate contribution of RAI to new heterosexually‐acquired HIV infections is suggested among at‐risk low‐income women in the US, meaning that tools to limit HIV transmission during RAI are required. Also they recommend collecting number of RVI and RAI acts to monitor heterosexually‐acquired HIV infections.
