2. Background Oral sex is a common practice and is increasing Oral sex is a common practice and is increasing Oral sex is a potential route for STD transmission Oral sex is a potential route for STD transmission Condom use with oral sex is not common Condom use with oral sex is not common Research indicates multiple factors deter condom use with oral sex Research indicates multiple factors deter condom use with oral sex

3. Objective Examine the differences in those who use condoms sporadically with oral sex in comparison to those who never use condoms for oral sex Examine the differences in those who use condoms sporadically with oral sex in comparison to those who never use condoms for oral sex Examine the prevalence and correlates of never using condoms for oral sex: Examine the prevalence and correlates of never using condoms for oral sex: Students on a college campus Students on a college campus STD clinic attendees STD clinic attendees

4. Methods: Sample Convenience sample Convenience sample College campus, southern U.S. College campus, southern U.S. Publicly funded STD clinic Publicly funded STD clinic Eligibility criteria: Eligibility criteria: no previous HSV-2 diagnosis no previous HSV-2 diagnosis speak English speak English sexually active past 3 months sexually active past 3 months Analysis limited Analysis limited those without current symptoms of HSV-2 those without current symptoms of HSV-2 those reporting oral sex in last 3 months those reporting oral sex in last 3 months

5. Methods: Data Collection Cross-sectional Cross-sectional Self-administered questionnaire Self-administered questionnaire sexual behavior measures sexual behavior measures 5 item version of Herpes Related Quality of Life scale (Cronbach α =.84) 5 item version of Herpes Related Quality of Life scale (Cronbach α =.84) HSV-2 Rapid Test: Sure-Vue® HSV-2 by Fisher HealthCare (Houston, TX); 96% sensitive; 98% specific HSV-2 Rapid Test: Sure-Vue® HSV-2 by Fisher HealthCare (Houston, TX); 96% sensitive; 98% specific

6. Methods: Data Analysis Assessed variables for normality; median split for non-normal variables Assessed variables for normality; median split for non-normal variables SPSS 14.0, χ 2, logistic regression SPSS 14.0, χ 2, logistic regression Significance at α =.05 Significance at α =.05

10. Results: Multivariate Associations Recruited from college campus Recruited from college campus Adjusted Odds Ration [AOR] = 6.03 Adjusted Odds Ration [AOR] = 6.03 95% Confidence Interval [CI] = 2.92-12.45 95% Confidence Interval [CI] = 2.92-12.45 P <.0001 P <.0001 Increased sexual frequency (12 < penile-vaginal sexual acts measured in past 3 months) Increased sexual frequency (12 < penile-vaginal sexual acts measured in past 3 months) AOR = 1.91 AOR = 1.91 95% CI = 1.03-3.54 95% CI = 1.03-3.54 P = 0.039 P = 0.039 Never using condoms for penile-vaginal sex Never using condoms for penile-vaginal sex

11. Discussion Greater frequency of penile-vaginal sex and never using condoms for penile-vaginal sex were associated with never using condoms for oral sex Greater frequency of penile-vaginal sex and never using condoms for penile-vaginal sex were associated with never using condoms for oral sex Possibly characteristic of relationship as with penile- vaginal sex Possibly characteristic of relationship as with penile- vaginal sex Condoms possible barriers to sexual pleasure / orgasm Condoms possible barriers to sexual pleasure / orgasm

12. Discussion Students in college may be at increased risk for never using condoms for oral sex. Students in college may be at increased risk for never using condoms for oral sex. May engage in sexual risk behaviors with less consequence; STDs less prevalent in their network May engage in sexual risk behaviors with less consequence; STDs less prevalent in their network May be less exposed to sexual health promotion messages than those attending STD clinic May be less exposed to sexual health promotion messages than those attending STD clinic Other significant bivariate associations definitive of student sample Other significant bivariate associations definitive of student sample

13. Limitations Cross-sectional, convenience sample, sample bias Cross-sectional, convenience sample, sample bias Self-report of sensitive behaviors Self-report of sensitive behaviors Did not assess oral sex as specifically “given” or “received” Did not assess oral sex as specifically “given” or “received” Did not assess participant knowledge of condom use with oral sex Did not assess participant knowledge of condom use with oral sex Unprotected oral sex questions specific to condom use Unprotected oral sex questions specific to condom use

14. Implications for Public Health Findings may be used to better guide educational efforts (ie college students in South) Findings may be used to better guide educational efforts (ie college students in South) Condom use messages directed to penile-vaginal sex may include oral sex messages Condom use messages directed to penile-vaginal sex may include oral sex messages Prevention directed at oral condom use may consider specific sexual partnerships Prevention directed at oral condom use may consider specific sexual partnerships

15. Conclusion Findings suggest that increased sexual frequency and never using condoms for penile-vaginal sex are characteristics of those who never use condoms for oral sex Findings suggest that increased sexual frequency and never using condoms for penile-vaginal sex are characteristics of those who never use condoms for oral sex Additionally, students on college campuses may be at increased risk of never using condoms for oral sex Additionally, students on college campuses may be at increased risk of never using condoms for oral sex
