  1. Condom Induced Erectile Dysfunction - COINEDA unique predictor of deliberate sexual risk (barebacking) Udi Davidovich, Merel Lammers, Maria Prins, Ineke Stolte Amsterdam Health Services - Department of Research

  2. Background & Methods • Find discriminative predictors for intentional versus incidental UAI • COINED - assumed predictor for intentional UAI • 435 ACSHM men, mean age 34 (SD=7.7, range: 18-67), HIV+ 6% (26) • Longitudinal analysis: predictors at time 1, outcome 6 months later • COINED: self reported, corrected for non-COINED • Sexual risk behavior: 2 multinomial outcome variables for casual and steady partners • Deliberate risk: self reported • Intentions to use condoms or engage in Negotiated Safety in the following 6 months • Multinomial regressions and mediation analysis (Baron & Kenny)

  3. Results • 10% (32/306) frequently experienced COINED with casual partners and 7% (19/272) with steady partners. • COINED was significantly associated with risky UAI with casual partners six months later(OR=2.71, 95%CI 1.06-6.95). • When Stratified to deliberate (e.g. barebacking) versus non-delibarate or incidental UAI, COINED was only predictive of deliberate UAI among causal partners(OR=6.57, 95%CI 2.14-20.18). • COINED was not associated with UAI with steady partners. • HIV status & age did not correlate with COINED or risk behavior. • Mediation analysis indicated that intentions to use condoms at time 1 completely mediated the effect of COINED on risky UAI six months later(see table 2, THPDC-205).

  4. Conclusions & Recommendations • COINED is a unique predictor of deliberate risk (e.g. bare-backing) as opposed to incidental risk between casual partners. • COINED most likely influences the intentions to use condoms in advance and, therefore, traditional motivation-based prevention strategies that increase risk perceptions or increase intention to use condoms will probably not be able to do the job. • Alternative prevention strategies, such as the prescription of erectile medication like Viagra, could be considered.
