Background The aim of this study is to describe homosexual experience and characteristics of recent homosexual encounters among Australian adults and identify changes between 2001-02 and 2012-13.
Computer-assisted telephone interviews were completed by a representative sample of 20094 men and women aged 16-69 years and the participation rate among eligible people was 66.2%. Respondents indicated the number of same-sex partners they had had in their lifetime and in the last 12 months. Those who reported any homosexual experience were asked the age at which this first occurred and about characteristics of the first and most recent homosexual encounter.
Reporting ever having same-sex experience was more common in women (13.5%) than in men (6.5%, P<0.001). Among these people, men reported more lifetime and recent same-sex partners than women (P<0.001). Same-sex experience was associated with some but not all indices of higher socioeconomic status. In men, it was associated with living in a major city (P=0.02) and in women, it was associated with younger (<30 years) age and with very low income (P<0.001). Men were younger than women at their first homosexual encounter (P=0.005). Women were more likely than men to have their first same-sex encounter with a regular partner. For women but not men, there was a significant increase in the proportion reporting same-sex experience since 2001-02.
Same-sex experience is not uncommon and is increasing in prevalence in young Australian women. The high number of same-sex partners among homosexual and bisexual men places them at greater risk of sexually transmissible infection.
背景 本研究旨在描述澳大利亚成年人的同性恋经历以及近期同性恋接触的特征，并确定2001 - 2002年至2012 - 2013年期间的变化。
由20094名年龄在16 - 69岁的男女组成的代表性样本完成了计算机辅助电话访谈，符合条件人群的参与率为66.2%。受访者指出他们一生中以及过去12个月内的同性伴侣数量。那些报告有任何同性恋经历的人被问及首次发生这种经历的年龄以及首次和最近一次同性恋接触的特征。
报告有过同性经历的女性（13.5%）比男性（6.5%，P<0.001）更常见。在这些人中，男性报告的一生中和近期的同性伴侣比女性更多（P<0.001）。同性经历与一些但并非所有较高社会经济地位指标相关。在男性中，它与居住在大城市有关（P = 0.02），在女性中，它与较年轻（<30岁）和极低收入有关（P<0.001）。男性首次同性恋接触时比女性年轻（P = 0.005）。女性比男性更有可能与固定伴侣发生首次同性接触。对于女性而非男性，自2001 - 2002年以来报告同性经历的比例有显著增加。
同性经历并不罕见，且在澳大利亚年轻女性中的患病率正在上升。同性恋和双性恋男性中同性伴侣数量众多使他们面临更高的性传播感染风险。
