At its core, LGBTQIA+ research seeks to understand the health, well-being and lived experiences of people whose sexual orientations and gender identities are too often misunderstood, overlooked or excluded. The acronym stands for lesbian, gay, bisexual, transgender, queer or questioning, intersex, asexual and others — representing a rich diversity that exists across every culture and community. Yet despite this, LGBTQIA+ populations face disproportionate barriers to health care, social acceptance and legal protections. This is where research plays a crucial role in identifying and addressing disparities.

Using rigorous, evidence-based methods, Michigan State University researchers explore how systems and environments impact health outcomes. Studies consistently show that LGBTQIA+ individuals experience higher rates of mental health issues, HIV, certain cancers, substance use and delayed or denied access to care. Without research, these disparities persist unchecked.

LGBTQIA+ research isn't political

Research drives better policy, supports inclusive health care practices and ensures that educators, clinicians and lawmakers are equipped with the knowledge to serve everyone fairly. It helps society develop inclusive mental health resources, equitable insurance policies and safer environments in schools and workplaces.

Additionally, research reveals that when environments are supportive, LGBTQIA+ communities thrive. There is growing evidence showing that people experience significantly improved outcomes when supported through gender-affirming care and inclusive environments.

Impacts of funding cuts

Canceling or cutting LGBTQIA+ research funding, particularly through major agencies like the National Institutes of Health, has wide-reaching consequences. When LGBTQIA+ research grants are reduced, the damage isn’t limited to one community. These cuts stall progress on issues like HIV prevention, opioid addiction, mental health and Alzheimer’s care. They may slow public health innovation, reduce opportunities for early-career scientists and diminish the nation's global research leadership.

For instance, Alzheimer’s disproportionately affects LGBTQIA+ older adults who often experience higher levels of stress, isolation and health care discrimination. Many live without traditional caregivers and encounter bias in medical settings. Research at MSU and beyond is helping develop inclusive screening tools and culturally responsive care models. Without continued support, these efforts may disappear — along with the hope they offer thousands of aging Americans.

Globally, the impact is just as serious. The U.S. has long played a central role in international HIV/AIDS research and LGBTQIA+ health initiatives. Defunding this work not only abandons at-risk populations worldwide but also signals a retreat from science-led diplomacy and humanitarian leadership. Fewer studies mean fewer solutions and greater barriers to health.

At MSU, research across health disciplines is critical to ensuring access to care for all.

MSU’s leadership in LGBTQIA+ health research

Aging and Alzheimer’s care

For decades, Associate Professor Anne Hughes in the School of Social Work, has been studying how discrimination, isolation and access gaps affect older LGBTQIA+ adults, individuals more likely to lack traditional family caregivers. Her findings help shape dementia screening and caregiving practices that are inclusive and culturally competent.

Community-engaged, trauma-informed psychology

Heather McCauley, associate professor in the School of Social Work, and Kaston Anderson-Carpenter Jr., associate professor in the Department of Psychology, develop sustainable mental health interventions centered on LGBTQIA+ voices and needs, combining research with real-world impact.

Inclusive health equity focus

Associate Professor Deirdre Shires leads the Consortium for Sexual and Gender Minority Health in the School of Social Work. Their team spans multiple colleges and is dedicated to understanding the mental, physical and community well-being of LGBTQIA+ individuals through interdisciplinary research and community engagement.

Sexual health and HIV prevention

Psychology Professor Robin Lin Miller leads groundbreaking studies on removing barriers to access to HIV prevention, testing and care in partnership with LGBTQIA+ communities of color around the world. She also studies global human rights initiatives for LGBTQIA+ people.

Sociology of transgender health care

Sociology Professor Carla Pfeffer researches the experiences of trans and nonbinary students at MSU and in the Greater Lansing area in hopes of improving the process of finding health care and sharing positive resources.

Transgender and nonbinary well-being

Jae Puckett, professor in the Department of Psychology, directs the Trans-ilience Research Lab, focusing on the lived experiences, stressors and resilience of transgender and nonbinary individuals. Their work informs mental health interventions and advocates for accessible, affirming care.

Ongoing investment in LGBTQIA+ health research enables scientific advancement, informs care models and benefits public health more broadly. From shaping national policy to improving local care, these efforts benefit not just LGBTQIA+ individuals but also everyone who values health and well-being.
