Factors Associated With Online Sex Partners Among Gay, Bisexual and Other Men Who Have Sex With Men: Results From a National Survey.

BACKGROUND

Associations between online sex seeking and increased risk for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) among men who have sex with men (MSM) typically rely on convenience samples. We examined Internet and mobile app use for finding sex partners among a nationally representative sample of MSM.

METHODS

We analyzed 2011 to 2017 data from the National Survey of Family Growth, a nationally representative sample of the civilian, non-institutionalized US population (15-44 years). The analytic sample was comprised of men who reported 1 or more same-sex partners in the past year. We also assessed associations between online sex-seeking and STI risk, sexual health care behaviors, and condom use.

RESULTS

Of 13,320 male respondents, 442 (3.0%) reported sex with a man in the past year, of whom 215 (46.3%) had met a partner online. Between MSM who met partners online and those who did not, we found no differences by age, education, race/ethnicity or socioeconomic status. Men who have sex with men with online partners were more likely to identify as gay (68.4% vs 49.5%, P = 0.0124). They also reported more sex partners overall (M = 3.04 vs 1.60, P < 0.0001), and multiple insertive (46.3% vs 8.5%, P < 0.0001) and receptive (33.2% vs 15.4%, P = 0.0055) anal sex partners, in the past year. They were also more likely to receive sexual risk assessments (56.0% vs 40.4%, P = 0.0129), STI testing (57.4% vs 35.3%, P = 0.0002), and STI treatment (17.8% vs 8.7%, P = 0.0152) in the past year. We found no differences in condom use.

CONCLUSIONS

Men who have sex with men who report using online sources to find sex partners are more likely than other MSM to report behaviors that increase risk for STI/HIV but are also more likely to engage in behaviors that may mitigate further transmission, such as STI testing.
