Practising unprotected anal intercourse UAI with high numbers of partners is associated with increased risk for acquiring and transmitting HIV and other sexually transmitted infections. Our aim was to describe factors associated with UAI with multiple partners in a large sample of MSM from 38 European countries recruited for an online survey in Overall, 9. Effective antiretroviral treatment drastically reduces HIV transmission for men diagnosed with HIV, irrespective of partner numbers. Apart from reducing partner numbers or increasing condom use no other recommendations are currently in place to reduce the risk of HIV acquisition and onward transmission for HIV-negative men practicing UAI with multiple partners. A range of factors were identified as associated with UAI with four or more partners which allow the strengthening and targeting of prevention strategies to reduce HIV transmission risks resulting from condomless anal intercourse with multiple partners. Peer Review reports. However, these numbers are likely to be inflated due to self- selection biases in the respective studies, while on the other hand self-reported prevalence underestimates HIV prevalence because it only includes diagnosed infections. Since the majority of MSM in Europe have been tested for HIV at least once [ 2 , 6 , 7 ] and intentional transmission or acquisition of HIV are extremely rare, most new transmissions occur when HIV serostatus is not or is incorrectly communicated between sex partners.

A meta-analysis was conducted from the results of published studies. Based on fourteen studies, MSM who were recruited online online-based group reported that A sensitivity analysis was used to test the reliability of the results, and it reported that the results remained unchanged and had the same estimates after deleting any one of the included studies. Targeted interventions of HIV prevention programs or services are recommended when designing preventive interventions to be delivered via the Internet.
