Sexual assault and coincident alcohol use in attendees at a genitourinary medicine clinic in the South of England

To investigate the relationship between alcohol consumption and the experience of sexual assault, either as victim or perpetrator, among genitourinary (GU) medicine department attendees in Portsmouth, UK, we carried out a cross-sectional survey of consecutive patients attending the walk-in service when a researcher was available. Self-completed questionnaires were used and anonymized data were collected from 1186 participants (response rate 34%). Responses showed that 15.6% of female and 3.7% of male participants had ever being sexually assaulted. Women who reported sexual assault drank more on a heavy night out than those who did not report sexual assault (mean 21.3 versus 17.0 units, P = 0.041). Over half of the victims had been drinking prior to the relevant assault. Twenty-seven participants (2.3%) admitted to having sex with a person who was not fully willing. Of these, 59% had been drinking prior to the assault, and the majority believed alcohol had contributed to the assault. Any strategies aiming to reduce the incidence of sexual assault must address hazardous drinking as a high priority.
