Background Anal and oral sex are related to the acquisition
and transmission of STIs, and condom use remains low for
these behaviors. Thus, we examined associations between these
behaviors and STIs using 2011–2015 National Survey of Fam-
ily Growth data.
Methods We examined associations between male-female penile
anal intercourse (PAI) and oral sex with opposite-sex partners
only (lifetime) and lifetime self-report of a viral STI (herpes
or genital warts) by sex and race/Hispanic origin (White, His-
panic, Black, Other). The response rate was 71.0% and sensi-
tive survey items were asked using audio computer-assisted
self-interview. Analyses were restricted to individuals reporting
one lifetime sex partner. Bivariate analyses were analyzed in
SUDAAN-11.0 using chi-squares.
Results Overall, more women (12.5%, N=11,243) than men
(2.1%, N=9,257) reported ever having a viral STI. Self-report
of viral STI was slightly more common among White women
compared to women of other racial/ethnic groups. Among
women, ever engaging in PAI was strongly associated with a
viral STI diagnosis (21.8%[SE 1.2] White, 20.7%[SE 2.0]
Black, 19.7%[SE 3.2] Other, and 16.9%[SE 1.7] Hispanic,
p<0.0001) as was giving/receiving oral sex (all 11.6%–17.3%).
For men, the same associations differed by race/Hispanic ori-
gin. PAI was significantly associated with a viral STI in White
men (5.7%[SE 0.7], p<0.01), Hispanic men (3.4%[SE 1.0],
p<0.05), and men of other racial/ethnic groups (2.7%[SE
1.2], p<0.05). Oral sex was associated with a viral STI in
White men and men of other racial/ethnic groups; however,
for Black men only giving oral sex was significantly associated
with a viral STI (4.1%[SE 1.0], p<0.05).
Conclusion For women, PAI and oral sex were related to hav-
ing been diagnosed with a viral STI. Self-reported viral STIs
were highest in women and Whites which may suggest dispar-
ities in health care seeking and access. Further exploration is
needed to assess associations between multiple sex partners
and condom use during these behaviors.

Background Rarely are Two-Spirit and/or Aboriginal (i.e., First
Nations, Métis, and Inuit) gay, bi, or men who have sex with
men (gbMSM) included in research projects that center their
experiences and ways. This study examines the main drivers
of sexual health knowledge (SHK) among Aboriginal (N=365)
and Two-Spirit respondents of Sex Now 2014-15 (SN15), a
national periodic survey conducted by the Community Based
Research Centre for Gay Men’s Health in Vancouver.
Methods Associations were examined between SHK, using a
combined score of 6 survey questions, and the following
explanatory variables: Two-Spirit identity, living in urban set-
tings, income, education and gay peer networks (GPN). Corre-
lations between explanatory variables were examined using
unadjusted odds ratios, and univariate and multivariable linear
regression estimated associations between each of the explana-
tory variables and the SHK outcome.
Results Using the Lakota expression, Mitakuye Oyasin, “all
my relations,”the drivers studied were interrelated: those liv-
ing in urban environments had larger GPN; higher educational
attainment had more income; and larger social support net-
work had higher levels of educational attainment and larger
GPN. Three main factors were positively associated as drivers
of SHK: income, education, and size of GPN. Two-Spirit
respondents had higher SHK than other Native men in urban
settings but not in non-urban settings.
Conclusion To increase SHK with those with lower levels of
education or income, or who are not connected to the “gay”
community requires new ways of conducting outreach and
engagement. Urban Two-Spirit folks are likely connected to
one another and may get better information related to HIV
prevention technologies, which may differ from those living in
rural settings. Further research is needed with a larger sample
and additional survey questions specific to experiences of Abo-
riginal gbMSM.

Background The Comarca Ngäbe-Buglé (CNB), situated in
western Panama, is home to over 200,000 indigenous peoples;
the region has the highest levels of multidimensional poverty
in the country. The prevalence and correlates of syphilis and
HIV have not been previouslydescribed among adolescents of
CNB.
Methods A cross sectional study, using multistage cluster sam-
pling design with equal probability of selection and random
sampling of clusters, among male and female participants aged
14–19 years, was conducted in 10 high schools in CNB from
July-November 2018. A questionnaire was self-administered,
participants provided blood, as well as urine and self-adminis-
tered cervical/vaginal swabs for STI testing (data not shown).
Serum was tested for HIV using rapid test/viral load
