Duration: March 2000 - September 2010 Sigma Research has been working with Ireland's Gay Health Network (GHN) since 2000. GHN is an umbrella organisation working towards gay men's health and HIV prevention. GHN instigated a community-based, self-completion survey to take place across The Republic of Ireland and Northern Ireland during the summer of 2000 and commissioned Sigma Research to work with them. This large-scale community research project was the third such survey among gay men in Ireland, and built on previous findings. After the development and piloting of the survey, recruitment commenced at Dublin Pride in June 2000 and continued throughout the summer at similar events in Belfast, Derry, Galway, Limerick and Waterford. Recruitment in bars and clubs took place in Dublin and Cork, and social groups in more rural area were sent copies of the questionnaire and a request to distribute them to their members. 1,290 questionnaires were returned by gay men (81%), bisexual men (11%) and other homosexually active men living in Ireland. 19% of all respondents lived in Northern Ireland. A full survey report, including implications for HIV prevention planning is available to download. Since 2003 Gay Health Network members - particularly The Gay Men's Health Service (Health Services Executive) and the Rainbow Project, Northern Ireland - have collaborated with our online UK version of the Gay Men’s Sex Survey (Vital Statistics) by promoting it to men in Ireland via community websites and postcards distributed on the gay scene. Real Lives, a summary report covering the main GMSS 2003 and 2004 data for men resident on the island of Ireland, was published in June 2006 and is available to download. It was published with The Gay Men's Health Service, Health Services Executive and the Rainbow Project. Real Lives II, a summary report covering the main GMSS 2005 and 2006 data for men resident on the island of Ireland, was published in June 2009 and is available to download. It was published with The Gay Men's Health Service, Health Services Executive and the Rainbow Rpoject. A summary report for Irish-resident men taking part in GMSS 2007 and 2008 will be published in June 2010.
