Details of meta-analytic outcomes
| Outcome | Details |
|---|---|
| Ever had sex with a male in lifetime | Ever sex or sexual contact with a male partner was asked in some studies that defined their ASMM study population based on a non-heterosexual identity; this outcome was not reported in studies that defined their ASMM population based on history of sex with a male. How the question was asked, and thus how the outcome is defined, varied by study. Sex or sexual contact with a male partner in lifetime was not defined in three articles, was specified as oral or anal sex in the fourth, and as any genital contact in the fifth |
| Recent sex | Recent sex was not consistently defined, nor was the population consistent. The recent sex outcome consolidated articles reporting sex in the last 3 or 6 months, and included articles describing recent anal sex, anal sex with males, sex with a male without specifying type, and sex not specifying either gender or type of sex. Recent sex was reported either among people who previously had sex in their lifetime or among all ASMM in the study |
| Any condomless anal sex in past 6 months | Condomless anal sex was reported among those who had sex in the last 6 or 12 months. One paper specified condomless anal sex with a male while the other four did not specify gender of partner. Three papers mentioned that the studies asked about condomless sex with both receptive and insertive anal sex roles, while two studies did not specify role |
| No condom use at last sex | Reported among ASMM who had sex in their lifetime, and type of sex and partner gender were not specified |
| Alcohol or drug use at last sex | Reported among ASMM who had sex in their lifetime, and type of sex and partner gender were not specified |
| Age at first sex ≤ 13 | Articles did not specify type of sex or gender of partner, and articles reported only among ASMM who reported ever having sex |
| Forced sexual contact in lifetime | Articles did not specify type of sex or gender of person, and articles reported only among ASMM who reported ever having sex |
| Mean number of lifetime sexual partners | Articles did not specify gender of partners or type of sex |
| Mean age at first sex | Articles did not consistently report partner gender or type of sex at sexual debut |
