Objectives: We examined the proportion of studies funded by the National Institutes of Health (NIH) that focused on lesbian, gay, bisexual, and transgender (LGBT) populations, along with investigated health topics.
Methods: We used the NIH RePORTER system to search for LGBT-related terms in NIH-funded research from 1989 through 2011. We coded abstracts for LGBT inclusion, subpopulations studied, health foci, and whether studies involved interventions.
Results: NIH funded 628 studies concerning LGBT health. Excluding projects about HIV/AIDS and other sexual health matters, only 0.1% (n = 113) of all NIH-funded studies concerned LGBT health. Among the LGBT-related projects, 86.1% studied sexual minority men, 13.5% studied sexual minority women, and 6.8% studied transgender populations. Overall, 79.1% of LGBT-related projects focused on HIV/AIDS and substantially fewer on illicit drug use (30.9%), mental health (23.2%), other sexual health matters (16.4%), and alcohol use (12.9%). Only 202 studies examined LGBT health-related interventions. Over time, the number of LGBT-related projects per year increased.
Conclusions: The lack of NIH-funded research about LGBT health contributes to the perpetuation of health inequities. Here we recommend ways for NIH to stimulate LGBT-related research.
