AbstractBackgroundAccording to the Alzheimer’s Association, approximately 350,000 LGBTQIA+ older adults in the U.S. currently have Alzheimer’s disease and related disorders (ADRD), increasing to over a million by 2030. Our recent research suggests that 1 in 7 LGBTQIA+ older adults report problems with their memory and thinking (subjective cognitive decline), which was much higher than their cisgender (not transgender), heterosexual counterparts. However, very few studies have assessed the cognitive function of LGBTQIA+ older adults.MethodsWe are utilizing tailored recruitment and engagement strategies to recruit a racial/ethnically diverse sample of at least 250 LGBTQIA+ and 250 non‐LGBTQIA+ older adults aged 50+ from the U.S. with a range of cognitive function from healthy to mildly impaired. Our recruitment and engagement approaches are guided by community‐based participatory research approaches that focus on building trust, collaboration, cultural humility, and giving back to the community.ResultsWe have been utilizing novel methods to recruit and engage LGBTQIA+ older adults and community organizations across the U.S. into The Stonewall Generations Study. Our current efforts involve a diverse recruitment plan that relies on recruitment via social media (e.g., Facebook, Twitter), referrals from community organizations, local outreach (tabling at community resource fairs, attending Pride and other LGBTQIA+ focused events), presenting to LGBTQIA+ aging service organizations, and developing unique social and educational engagement events.ConclusionsOur current efforts to recruit and engage LGBTQIA+ older adults are important because they can help to identify ways to improve representation of diverse communities in Alzheimer’s disease and aging research. There is a need for tailoring research and recruiting and engaging diverse older adults, especially LGBTQIA+, into research and finding ways to address the health and Alzheimer’s disease risk of underserved populations. The Stonewall Generations Study aims to increase knowledge of culturally‐relevant recruitment and engagement strategies and identify targets for preventative interventions to decrease ADRD risk among LGBTQIA+ older adults.
