Background/introduction Studies show that use of dating apps amongst men who have sex with men (MSM) is associated with an increased risk of sexually transmitted infections (STIs), including HIV. There is a paucity of research regarding the use of similar apps amongst the heterosexual population.

Aim(s)/objectives To quantify heterosexual use of dating apps and explore the sexual practices of app users.

Methods Anonymised questionnaires were offered to heterosexual attendees of two GUM clinics, throughout August 2015. Respondents self-completed information relating to purpose and frequency of app use, number of sexual partners, recreational drug use (RDU), condomless sex and STI diagnoses.

Results Questionnaires were returned by 539 attendees: 70% (377) women, 30% (162) men. Median age was 21–30 years.

Discussion A quarter of heterosexual GUM attendees frequent apps to find partners. This study identified high rates of STIs, condomless sex and RDU amongst app users, with rates mirroring those seen amongst MSM. Sexual health promotion and/or STI testing packages would be welcomed by most app users.

Conclusion A quarter of heterosexual GUM attendees frequent apps to find partners. This study identified high rates of STIs, condomless sex and RDU amongst app users, with rates mirroring those seen amongst MSM. Sexual health promotion and/or STI testing packages would be welcomed by most app users.
