  3. 3.  Background:  New Zealand’s HIV Epidemic  Younger Gay Men & HIV Objectives Methods: HIV sociobehavioural surveillance Results:  Younger Gay Men vs Older Gay Men Conclusions Future Research & Next Steps Questions & Dialogue
  4. 4.  Gay men continue to be Characteristics of MSM % Diagnosed with HIV in disproportionately and New Zealand, 2010 predominantly affected (n=90) by HIV in New Zealand Ethnicity  71.4% of new HIV NZ European/Pakeha 71 diagnoses in 2010 Maori 10  2010 was 2nd highest Asian 10 number of new Pacific 1 diagnoses in New Infected in New Zealand 71 Zealand’s history Late Diagnosis 48 Age 15-29 at Diagnosis 32
  5. 5.  Unique New Zealand context and experience of younger gay men (YGM)  Increased rights: Homosexual Law Reform 1986, Human Rights Acts 1993, Civil Unions 2005  Availability of effective HIV treatments: HAART 1997  Improved prognosis for HIV-positive individuals  Connectedness to “gay community”: less or different? International interest in YGM  New generation; “post-AIDS” era  Recent increase in HIV infection rates within USA
  6. 6.  Compare HIV-related knowledge, attitudes, and behaviours between:  Younger gay men (YGM) & older gay men (OGM) ▪ YMSM: 16 – 29 years of age ▪ OMSM: 30+ years of age Focus on and strategy of primary prevention
  7. 7.  Pooled sample of 3387 YGM and 5602 OGM from the 2006, 2008, and 2011 rounds of New Zealand’s sociobehavioural HIV surveillance  Gay Auckland Periodic Sex Survey (GAPSS) and  Gay men’s Online Sex Survey (GOSS) Anonymous and self-completed questionnaires Reproducible convenience sample Second-generation surveillance: “gold standard”  World Health Organization recommended

  15. 15.  YGM and OGM similarities and differences:  YGM less knowledge, fewer partners, less casual sex, more anal sex, and more condom use with boyfriends, but less with casual partners Need for strategic, targeted HIV/sexual health promotion for YGM and other YMSM Contributes to evidence-based health promotion and prevention efforts
  16. 16.  Strengths:  Novel research on YGM in New Zealand  Gold standard HIV sociobehavioural surveillance  Survey data collected both online and offline  Large pooled sample allowing sub-analyses Limitations:  Debate regarding “younger” definition/classification  Impact of online venue (not online sexual activity)  Univariate analyses presented, multivariate analyses can take into account other confounders
  17. 17.  Disseminate this research on YGM  Present to affected and interested groups  Post findings to community: blogs, news stories  Publish results: conferences and journal articles Continue with research plan  Multivariate analyses on condom use and HIV testing  Cross-ethnic analysis Advocacy and pressure for greater funding to continue and expand research efforts
  18. 18.  Expanded research into other communities  Different geographic areas in New Zealand  Other populations at risk of HIV infection Further investigation into differences between HIV-related risks for YGM  Sexual activity with partners met online vs offline Use qualitative research to help understand and explore sexual networks and concurrency Investigate resiliency and protective factors
