To promote health and quality of life by preventing and controlling
disease, injury, and disability.
In public health and in medicine, the concept of health-related
quality of life refers to a person or group's perceived physical and
mental health over time. Physicians have often used health-related
quality of life (HRQOL) to measure the effects of chronic illness in
their patients to better understand how an illness
interferes with a person's day-to-day life. Similarly, public health
professionals use health-related quality of life to measure the
effects of numerous disorders, short- and long-term disabilities,
and diseases in different populations. Tracking health-related
quality of life in different populations can identify subgroups with
poor physical or mental health and can help guide policies or
interventions to improve their health.
