Life Expectancy & Quality of Life


Improvement in the average age of death or how often illness and injury impedes everyday life for a particular population. Life expectancy measures how long a person can expect to live. Quality of life can be measured in terms of living conditions, physical health, mental health, social relationships, level of independence, economic security, safety, or basic human rights.


Enhancement of well-being among community members is a key goal of clinical and translational research. Increases in life expectancy and quality of life are frequently used to assess community health.


Advice from authors on searching for information:

Without specific analyses, it is challenging to attribute changes in quality of life or life expectancy of a population to the dissemination and implementation of a specific clinical and translational research project. Researchers may want to consult with domain-specific experts.
