Biological age (BA) is an individual’s physiological and psychological health, socioeconomic factors, and ability to take partake in desired activities. Functional status (FS) looks at whether a person can perform the daily activities necessary to meet basic needs. These concepts are recognized globally, but the definition of biological age lacks consistency in varying cultural contexts. This study uses variables from BA and FS to analyze whether they can be indicative of aging. Using R and the National Health & Aging Trends Study, a multi-variant cox regression looked at activities of daily living and instrumental activities of daily living, age-related changes, risk factors, and health history in relation to mortality over 7 years in people at least 65-years-old. This study looks at the effects of age-related changes and risk factors on a person’s health and functioning.
