Estimating population distribution and HIV prevalence among homosexual and bisexual men.
OBJECTIVE
To estimate the extent of the homosexual and bisexual male population in inner Sydney and HIV prevalence within this population.


METHODS
Data from the 2000/2001 Sydney Gay Community Periodic Survey (SGCPS) and the Australian Study of Health and Relationships were used.


RESULTS
A re-analysis of responses from men in some inner east and inner west postcode areas of Sydney indicated that: the proportion of men who identified as homosexual or bisexual ranged from 4.4% to 48.1%; from 9.8% to 51.5% of men reported same-sex experiences during their lifetime; and 12.9% to 52.8% of men had ever experienced feelings of same-sex attraction. HIV prevalence among respondents to the SGCPS in these same areas varied from 9.1% to 21.3%.


CONCLUSIONS
These findings indicate elevated proportions of men with same-sex identity, experience or attraction living in these inner Sydney locations compared with other geographic areas and illustrate how gay communities cluster.
