The World Health Organization (WHO) published a report in 2015 on aging and health, proposing the concepts of intrinsic capacity and functional ability and defining healthy aging as the process of developing and maintaining life function for a happy life in old age. The report emphasized the importance of improving health care services, long-term care systems, and environmental conditions to delay the loss of intrinsic capacity and maintain life functions. In 2020, WHO updated its report on healthy aging with modified concepts, evaluation methods, and policy goals.
This article provides an overview of the latest concepts in healthy aging and discusses the differences between the 2015 and 2020 reports. The 2020 report defines the three major factors of healthy aging as intrinsic capacity, functional ability, and environmental factors, rather than separating them as in the 2015 report.
Health aging is not just a concern for the elderly but a challenge that everyone must face. It is important for all people to have their human rights protected, including the right to make independent decisions and participate in society with adequate life functions. The government should also establish strategies and create a friendly environment for this purpose.
Population aging Taiwan is and will remain a major health challenge. Not just the government but also communities and the healthcare system need to implement interventions systematically, comprehensively, and proactively with clear goals to improve the functional ability of the elderly population.
