Conclusions Similar to other studies, condom use was more likely to be reported by persons most at risk; however, even among those at increased risk, fewer than half used condoms during most recent sexual intercourse. Background Young minority men in the US bear a disproportionate burden of STI, but comprise one of the population groups least likely to access services. STI service utilisation is not only constrained by access to quality care but also potentially impacted by socio-cultural factors, including STI-related stigma and shame, which can undermine efforts to promote testing and treatment. STI-related stigma and shame may also provide a disincentive for young men to participate in partner notification programs, including partnerdelivered therapy. We hypothesised that young men who perceive increasing levels of social stigma related to STI would be less likely to seek out STI-related services or notify their sexual partners about STI. Methods Between June and July, 2010, 108 African American young men (15d24 years) responded to a brief, self-administered intercept survey on a hand-held device. Recruitment was conducted on the street and in residential areas of a low income urban neighbourhood with elevated STI rates. The survey included socio-demographic questions, an 11 item scale measuring STI-related stigma and shame, and questions regarding STI testing history, preferences for notifying partners, and interest in partner delivered therapy. The association between stigma and shame scores and STI testing and partner notification preferences was evaluated with multivariate logistic regression, adjusting for age and education. Results The median (range) STI-stigma score was 12 (5e25) and the shame score was 15 (6e30); higher scores indicate more stigma or shame. Most participants had ever been tested for STI (73%), indicated willingness to personally notify their main partners (72%) or other partners (66%), and said they would deliver STI therapy to a partner (68%). Increasing STI-related stigma was significantly associated with a history of STI testing, such that every SD increase in stigma score was associated with 50% decreased odds of having been tested (OR: 0.5, 95% CI 0.3 to 1.0). Participants with higher levels of stigma and shame were also significantly less likely to be willing to personally notify their partners of STI or to deliver therapy. Conclusions STI-related stigma and shame, common in this population, could undermine STI testing, treatment, and partner notification programs. Efforts to expand access to care should be accompanied by efforts to change socio-cultural attitudes and norms around STI testing and treatment. P2-S3.05 ASSOCIATION OF STI-RELATED

small proportion (4%) indicated they had never had a Pap test. In multivariate models, having a Pap test in the past year was negatively associated with income >3500 pesos/month, more years in the sex trade and having regular clients. Marginal positive associations remained with older age, reporting condom use less than half the time with non-regular clients and having any children. Discussion Prevalence of pap tests in the past year was higher than expected and may be attributed to recent efforts by the Tijuana Municipal Health Services to increase outreach to FSWs in these areas. However, since initiating sex work, only half reported the recommended yearly Pap testing which is concerning given the increased risk for HPV infection and cervical cancer among FSW. Sexual health education, including where access services, is needed to encourage regular cancer screening among this high risk population, especially among younger women and women who have been working in the sex trade for longer durations. Objective Adolescent girls diagnosed with PID are at higher risk for subsequent sexually transmitted infection (STI), pregnancy, and long-term pelvic pain. Although the 72-h post-PID evaluation provides an opportunity for risk reduction counselling, few adolescents adhere. Use of public health nurses (PHN) for clinical followup may meet the needs of this vulnerable population. The objective of this study is to estimate consumers' willingness-to-pay (WTP) for follow-up PID services by physicians and PHNs, differences by consumer type, and the differences in health-provider predicted consumer WTP values and actual consumer WTP values. Methods A contingent valuation method was used to collect WTP data regarding co-payments to physicians or nurses for clinical service delivery from the consumers of adolescent PID services (parents (n¼121) and adolescents (n¼134)) and a national sample of health providers (n¼102). Consumers were recruited from an academic paediatric practice and school-based health clinics in a large urban community with high STI prevalence. Participants completed a web-based survey with data uploaded to a secure server after obtaining online consent. Data were analysed using linear regression analyses. Results The mean WTP for physician services was $16 (SD $16.9) for clinicians, $81.9 ($34.0) for parents, and $72 (SD $ 39.1) for adolescents. The mean WTP for PHN services was $13.6 (SD $17.4) for physicians, $62.4 (SD $44.1) for parents, and $49.7 (SD $44) for adolescents. Using physician estimates for WTP as the reference group, adolescents were willing to pay $56 more (95% CI 48.6 to 63.4) for physician care and parents were willing to pay $66 more (95% CI 59.0 to 72.8) than physician's predicted controlling for informant employment status. Adolescents were willing to pay $36 more (95% CI 48.6 to 63.4) for community-based nursing care and parents were willing to pay $48 more (95% CI 59.0 to 72.8) than physician's predicted. Consumers' (adolescents' & parents') WTP for physician services were on average ...
