Adult health refers to the overall well-being, physical, mental, and social, of individuals in the adult age group, typically defined as individuals aged 18 and older. Research in adult health focuses on a variety of factors that can impact health outcomes in this age group, including lifestyle behaviors, chronic disease management, mental health, access to healthcare, and social determinants of health. Studies in adult health aim to identify risk factors, develop interventions, and improve overall health and well-being in adulthood. This research area is critical for promoting healthy aging and reducing the burden of disease in older populations.
