Sexual orientation can be accurately identified from photos of faces, but previous work has focused exclusively on straight versus gay and lesbian individuals. Across three studies, the current work investigated the facial perception of bisexual men and women, a less socially salient category. Although participants could identify straight and gay men at above-chance levels in a trichotomous cat...

BACKGROUND While a large body of research has sought to understand HIV transmission risk behaviours among gay men, bisexual men and other men who have sex with men (MSM), less attention has been paid to the wider sexual health and well-being of this population. While some community-based organisations aim to support a more holistic sense of sexual well-being there is little evidence to draw on ...

For decades, investigators have sought to explain the increasing rates of suicide among adolescents and to identify remediable predisposing factors. Despite substantial progress, the possibility has been raised that existing research has overlooked important clues to the problem. Specifically, the contribution of bisexual and homosexual youth to suicide deaths has been a matter of recent intere...

OBJECTIVE This study evaluated whether sexual orientation-specific differences in substance use behaviors exist among adults entering substance abuse treatment. METHOD Admissions records (July 2007-December 2009) were examined for treatment programs in San Francisco, California receiving government funding. Lesbian, gay, and bisexual (LGB) persons (n = 1,441) were compared to heterosexual per...

BACKGROUND Web-based approaches, specifically social media sites, represent a promising approach for recruiting young gay and bisexual men for research studies. Little is known, however, about how the performance of social media advertisements (ads) used to recruit this population is affected by ad content (ie, image and text). OBJECTIVE The aim of this study was to evaluate the effects of di...

This study explored whether gender nonconformity in gay and bisexual men is related to mental distress and if so, whether this relationship is mediated by negative experiences that are likely associated with gender nonconformity, including abuse and harassment. To study this question, data were analyzed from face-to face interviews with 912 self-identified gay and bisexual Latino men in three m...

In Cacopsylla myrtilli (W. Wagner, 1947) bisexual populations, all-female populations and populations heavily biased towards females have been described. In the present paper all the available data on the distribution and population sex ratio of C. myrtilli are summarized. New data obtained by the authors are also presented. First records for Russia are described from Siberia and the southern p...

Same-gender sexual orientation has been repeatedly shown to exert an independent influence on suicidal ideation and suicide attempts, suggesting that risk factors and markers may differ in relative importance between lesbian, gay, and bisexual individuals and others. Analyses of recent data from the National Longitudinal Study of Adolescent Health revealed that lesbian, gay, and bisexual respon...

BACKGROUND China's population is quickly aging and this trend is expected to continue. Thus it is important to develop HIV interventions to help protect older Chinese from infection. Limited information exists regarding sexual risk behaviors and associated personal motivations among persons aged 50 and over in China. METHODS In-depth interviews were conducted with 12 HIV-infected and 14 uninf...

HIV/AIDS prevention messages catered to Anglo homosexual/bisexual men are not effective in teaching preventative behaviors to Hispanic homosexual/bisexual men. Hispanic sociocultural traits associated with homosexuality and bisexuality prevent the effectiveness of these messages. The Hispanic family is also extremely important in influencing behaviors. Successful HIV prevention messages geared ...
