Recent research has suggested that interpersonal communication may be an important source of stereotype maintenance. When communicated through a chain of people, stereotype-relevant information tends to become more stereotypical, thus confirming the stereotypes held by recipients of communication. However, the underlying mechanisms of this phenomenon have(More)
INTRODUCTION There is a lack of recent data on the extent to which gay men engage in insertive anal intercourse (IAI) and receptive anal intercourse (RAI). Accurate assessments of the overall risk of infection from HIV and other sexually transmitted infections (STIs) require such data because versatile men who engage in both roles have heightened(More)
OBJECTIVES To determine whether there is a link between age at first anal intercourse (AFAI) and gay men's HIV/sexually transmissible infection (STI) vulnerability, including tendencies to engage in higher risk sexual behaviour. METHODS A nationwide cross-sectional survey was conducted online involving 845 Australian gay men born between 1944 and 1993. (More)
INTRODUCTION AND AIMS Use of methamphetamine appears to be greater among gay men than in the general population, yet little data are available on factors associated with use, especially among older men. This study identifies factors associated with reported methamphetamine use among older Australian gay men. DESIGN AND METHODS Data were collected from an(More)
Men who have sex with men (MSM) are typically studied as though they were a homogeneous population. This has resulted in a lack of knowledge about the sexual health and behavior of bisexual men as distinct from gay men. In this study, patterns of sexual behavior and rates of HIV testing were compared between 854 gay-identifying and 164 bisexual-identifying(More)
With a vaccination program currently planned to protect Singaporean women from human papillomavirus, a need arises for assessing Singaporean women's knowledge of human papillomavirus and attitudes toward human papillomavirus vaccination to identify barriers to a successful program and to help inform health education campaigns. A representative sample of(More)
OBJECTIVES Lesbians and gay men are exposed to unique minority stressors. We examined the health implications of one type of distal minority stressor (victimisation) and one type of proximal minority stressor (sexual identity concealment due to anticipated stigma) among lesbians and gay men. Gender-specific health implications were assessed. METHODS Data(More)
BACKGROUND Education campaigns seeking to raise awareness of human papillomavirus (HPV) and promoting HPV vaccination depend on accurate surveys of public awareness and knowledge of HPV and related sexual behavior. However, the most recent population-based studies have relied largely on computer-assisted telephone interviews (CATI) as opposed to face to(More)
Since the introduction of highly active antiretroviral therapy, people living with HIV/AIDS (PLWHA) are living longer, into older age, and therefore presenting a host of new challenges for health and social service providers. However, not all PLWHA are likely to experience similar transitions into older age. In particular, research has yet to fully(More)
Little is known of men's knowledge of cervical cancer and its links with human papillomavirus (HPV), or of their attitudes and beliefs about HPV vaccination. This is despite men's sexual behaviour contributing to HPV transmission and their potential role in deciding whether their children are vaccinated against HPV. To address this, a comprehensive survey(More)
