Health related quality of life (HRQoL) refers to a comprehensive assessment of an individual's physical, mental, emotional, and social well-being. HRQoL is a vital concept in public health, helping to identify and quantify the burden of disease on a population. Synonyms for HRQoL include wellness, well-being, health status, health outcome, and health-related functioning. These terms also encompass the broader aspects of public health, including environmental, social, and economic factors that influence health outcomes. The measurement of HRQoL can be done through surveys, questionnaires, and other assessment tools. Understanding the HRQoL of individuals and populations can help public health practitioners develop programs and interventions to promote healthier lifestyles and provide better health care services.
