Association between chronotype and body mass index: Role of C-reactive protein and the cortisol response to stress

Abstract

The exponential aging of population all across the world has its own significance and implications as it pertains to older adults. The incidence of comorbidities and disability is high in this age group, resulting in functional decline as a result of physiologic, pathophysiologic, environmental, and socioeconomic conditions. Functional decline leads to decreased cognition, mobility, and activities of daily living. This chapter discusses aging demographics, normal aging physiology, mechanisms of aging, implications of multimorbidity, geriatric syndromes including frailty, disability, emerging complex care team models, the role of physical activity in the prevention and treatment of common age-related conditions, and the role of the physiatrist in geriatric care models.
