Associations Between Sexual Type and HBV Infection
According to the questionnaire, sexual type was classified into nine
groups, individuals with no sex (3.94%), heterosexual vaginal sex
(10.23%), heterosexual oral sex (0.59%), heterosexual anal sex
(0.04%), heterosexual multiple types (77.36%), bisexual sex (6.71%),
male homosexual sex (0.74%), female homosexual sex (0.09%), and
unclear (0.3%).
In comparison to participants without sexual behavior, we found that
bisexual sex and male homosexual sex were found to be linked with an
increased likelihood of contracting HBV infection. Specifically, in
model 1, bisexual sex (OR=1.73, 95%CI: 1.15-2.59) and male homosexual
sex (OR=4.82, 95%CI: 2.25-10.31) were identified as having a higher
risk of HBV infection. In model 2, bisexual sex (OR=2.2, 95%CI:
1.44-3.36) and male homosexual sex (OR=6.58, 95%CI: 2.99-14.46) were
correlated with an increased risk of HBV infection. Similarly, in model
3, bisexual sex (OR=1.69, 95%CI: 1.04-2.76) and male homosexual sex
(OR=5.23, 95%CI: 1.95-13.99) were correlated with a higher risk of HBV
infection. Conversely, there were no significant differences observed in
heterosexual vaginal sex, heterosexual oral sex, heterosexual anal sex,
or heterosexual multiple types across the three models.
Upon stratification by gender, in the men population, comparing with men
without sexual behavior, heterosexual anal sex (OR=14.42, 95%CI:
3.66-56.81), bisexual sex (OR=4.32, 95%CI: 2.51-7.44) and male
homosexual sex (OR=5.61, 95%CI: 2.53-12.48) exhibited an increased risk
of HBV infection in model 1. Heterosexual anal sex (OR=4.75, 95%CI:
1.22-18.47), bisexual sex (OR=4.34, 95%CI: 2.43-7.77) and male
homosexual sex (OR=7.75, 95%CI: 3.43-17.52) were found to be linked
with an increased risk of HBV infection in model 2. Heterosexual anal
sex (OR=4.52, 95%CI: 1.12-18.2), bisexual sex (OR=4.00, 95%CI:
2.09-7.64) and male homosexual sex (OR=5.65, 95%CI: 2.13-15) were found
to be linked with an increased risk of HBV infection in model 3. No
significant differences were observed in heterosexual vaginal sex,
heterosexual oral sex, or heterosexual multiple types across all three
models.
However, among the women population, compared with women without sexual
behavior, whether heterosexual vaginal sex, heterosexual oral sex,
heterosexual multiple types, bisexual sex, no statistically differences
were observed across three models.
