Bisexuals, gays, lesbians face greater health risks: study

Washington, United States:  Bisexual, gay and lesbian adults are more likely to experience psychological distress and engage in unhealthy behaviors, possibly as a result of being the target of discrimination, according to a study published Monday.

The study in the US medical journal JAMA Internal Medicine analyzed the results of the 2013 and 2014 National Health Interview Survey, which for the first time included a question on sexual orientation.

"Findings from our study indicate that LGB adults experience significant health disparities particularly in mental health and substance use likely due to the minority stress that LGB adults experience as a result of their exposure to both interpersonal and structural discrimination," the study said.

The analysis showed that 40.1 per cent of bisexual men and 25.9 per cent of gay men reported moderate or severe levels of psychological distress, compared to 16.9 per cent of heterosexual men.

Heavy drinking was reported by 10.9 per cent of bisexual men, compared with 5.7 per cent for heterosexual men and 5.1 per cent for gay men.

Rates of heavy smoking were also highest among bisexual men at 9.3 per cent, compared to 6.2 per cent for gay men and six percent for heterosexual men.

Among women, 46.4 per cent of bisexuals and 28.4 per cent of lesbians reported moderate and severe psychological distress, compared with 21.9 per cent of heterosexual women.

Bisexual women also had the highest rates of heavy alcohol consumption, 11.7 per cent, compared with 8.9 per cent for lesbians and 4.8 per cent for heterosexual women.

Heavy smoking was most prevalent among lesbian women at 5.2 per cent, followed by bisexual women at 4.2 per cent. The rate among heterosexual women was 3.4 per cent.

The negative findings for bisexual adults may be linked to their "marginalization" by heterosexuals and "stigma" from gays and lesbians, according to the study, led by Gilbert Gonzales of Vanderbilt University.

JAMA Internal Medicine Deputy Editor Mitchell Katz wrote in an editor's note that it's important for medical professionals to ask patients open-ended questions.

"For example, asking a new patient whether he or she has sex with men, women or both indicates openness and acceptance," he said. "In caring for people who have experienced bias and discrimination, support is a very potent medicine."

The study compared responses from 525 lesbian, 624 gay and 515 bisexual adults with those of 67,150 heterosexual peers. The average age of participants was nearly 47.
