Gain a thorough understanding of the determinants of health among aging populations, how disparities arise in diverse communities, and what can be done Reducing health disparities among older people is critical to slowing or reversing the individual and societal impacts of aging-related conditions like Alzheimer's and dementia. The field of population science can help us understand disparities and prevent them using community-wide strategies. Population Science Methods and Approaches to Aging and Alzheimer's Disease and Related Dementias Research offers an overview of the population health approach, applying this framework to aging-related conditions and their determinants. By working hand-in-hand with diverse communities to address these conditions we can develop primary and secondary prevention strategies that can increase health equity for all Americans. Included topics range from population health trends and approaches to understanding community and patient engagement to caregiver perspectives and emerging trends. * Learn about the population science approach to understanding aging-related health concerns in diverse communities * See how factors like race, income, sexual orientation, sleep, and community engagement affect Alzheimer's and related dementias * Read about proactive approaches to primary and secondary prevention within aging populations * Discover emerging research and public health initiatives currently underway to promote health equity Students, researchers, and practitioners alike will benefit from this primer on participatory approaches to reducing health disparities. This introduction to the landscape of aging research in the most vulnerable of our communities will facilitate creativity, compassion, and meaningful next steps in biomedical and socioecological research, community support, and clinical care. A thorough overview of research on aging-related cognitive conditions, with helpful resources for students, clinicians, and practitioners Population science addresses health from a community-based perspective, informing our understanding of the social determinants of health in diverse populations, with the goal of increasing health equity for all. Population Science Methods and Approaches to Aging and Alzheimer's Disease and Related Dementias Research aims to introduce readers to population health and health equity in the context of aging-related research. With an emphasis on minoritized, limited English proficient, and low-income communities, this book covers the conditions that lead to disparities in cognitive health as we age--and how those disparities might be addressed at a community level. Each of this book's edited chapters includes learning objectives and discussion questions to facilitate active learning. Readers will gain a foundational knowledge of the population science framework, as well as a newfound compassion and an understanding of meaningful next steps toward equity. Researchers and practitioners alike will discover new directions for reducing health disparities among older people and engaging in prevention for aging-related conditions.
