Ageing explained
These changes are neither linear nor consistent, and they are only tangentially related to age in years. In addition to physical changes, aging is frequently linked to other life transitions such as retirement and relocation.
Common health conditions associated with ageing
Hearing loss and cataracts are common conditions in older people, as are frailty, urinary incontinence, falls, delirium, and pressure ulcers. Geriatric syndromes include frailty, urinary incontinence, falls, delirium, and pressure ulcers.
Factors influencing healthy ageing
Maintaining healthy behaviors throughout life can reduce the risk of noncommunicable diseases, and supportive physical and social environments enable people to do what matters to them.
Challenges in responding to population ageing
Globalization, technological advancements, urbanization, migration, and changing gender norms are all influencing the lives of older people. Public health professionals and society as a whole must address ageist attitudes.
WHO response
The WHO Global Strategy and Action Plan, as well as the United Nations Madrid International Plan of Action on Ageing, serve as foundations for the Decade of Healthy Ageing (2021u20132030), which aims to reduce health inequities and improve the lives of older people, their families, and communities.
