The study found that even people identifying as “mostly” heterosexual had higher rates of asthma than those who identified as exclusively heterosexual. Mostly heterosexual individuals may also face discrimination but may not be “out” and have access to the social support and communities available to “out” LGBTQ+ people.

"Medical professionals, social workers, and clinicians need to be aware of these sexual orientation disparities in health outcomes," said co-author, Kyle T. Ganson, PhD, assistant professor at the University of Toronto’s Factor-Inwentash Faculty of Social Work. "Providing appropriate and tailored care is needed to address these disparities."

“Some sexual minorities may be less likely to seek care due to barriers to accessing health care or experiences of discrimination at a clinician’s office. Doctors should offer materials on LGBTQ health, publicize nondiscrimination statements and have inclusive forms for sexual minorities,” Nagata added, “so that they’re not discouraged from seeking care.”
