title: [Population aging and public health. The active aging concept].
abstract: Population aging has been recognized as one of the most important human achievement, being the result of improved living conditions and medical advances. According to UN Projections, in the year 2025 there will be living in the world 1.2 billion elderly people, and 71 % of them are likely to be in the developing countries. Between 1950 and 2025, the "Old" Old (those who are 80 years and above) will grow twice as fast as the 60-plus age group. In these conditions, we are confronted with two major issues: providing older people with opportunities for independence, health, productivity, and protection while at the same time maintaining economic prosperity in society. These two issues will require multiple economic, financial and social changes. The concept of quality of life is expressed in this large chapter about aging through active aging, which is depending on social and economic factors, personal and behavioural factors, health and social services, environment, gender and culture. The programmes for promoting active aging have to encourage healthy life styles, including healthy nutrition policies, active life and avoidance of chronic illnesses.
