CI: Confidence interval; MSM=Men who have sex with men. Percentages may not add to 100 due to rounding.
Note: Persons who reported the behavior was inapplicable or with missing data for that characteristic or behavior were excluded from the denominator.
Participants with Hispanic or Latino/a ethnicity were categorized as Hispanic and might be of any race; persons with non-Hispanic ethnicity were categorized into single race groups or as multiracial. Participants reporting multiracial identity were not shown separately.
Men, including transgender men, were categorized as gay, bisexual or other MSM if they reported sex with men or a transgender male partner in the past 14 days or reported they were gay or bisexual. The remaining men and transgender men were grouped as men who had sex with women if they reported sex with only women or transgender women in the past 14 days and reported a sexual orientation of straight. Women included those who self-identified as women or transgender women, regardless of reported gender identity of sex partners or sexual orientation. The other category includes 41 participants who reported “other” gender identity and 17 participants who did not specify gender of sex partner.
In the past 14 days.
