What is the definition of healthy aging? How to measure it?

Thanks for your kind comment as well.

I extend my sincerest gratitude.

Healthy aging is defined as the process of developing and maintaining functional ability that enables well-being in older age, as stated by the World Health Organization. It emphasizes the importance of intrinsic capacity, which includes physical and mental abilities, and the influence of environmental factors.

To measure healthy aging, researchers often use various assessments, including:

Functional ability tests: Evaluating mobility, strength, and daily living activities.

Health questionnaires: Assessing physical and mental health status.

Quality of life scales: Measuring overall well-being and life satisfaction.

These tools help identify areas for improvement and monitor progress in older adults.
