We are witnessing an unprecedented demographic shift: the transition from high to low birth and death rates has global political, socioeconomic and health economic consequences.
An important point of this change is the growth in the number and proportion of older people. Since the mid-19th century, life expectancy has been increasing at a rate of about three months/year. Currently, global life expectancy is 66 years, and one in ten people is 60 or older; by 2050, one-fifth and by 2150, one-third of the world’s population will be 60 or older, while only one-sixth will be under 20. The total elderly population is projected to increase from 605 million in 2000 to 1.2 billion in 2025 and to nearly 2 billion in 2050. For years, the Japanese topped the list of highest life expectancy. Since 2012, Switzerland has been ahead of Japan for the first time, which has slipped to second place with a life expectancy of 82.8 years. The reasons lie in Switzerland’s higher economic growth, higher spending on the healthcare system and a significantly lower rate of cancer deaths.
These records are accompanied by aspects that give pause for thought: More and more people are living longer in a stage of life influenced by illness – which is to be improved or even extended. In Japan, sales of adult diapers have exceeded those of baby diapers since 2012.
These demographic changes affect all aspects of society, such as work and jobs, infrastructure and mobility, social insurance and services. The consequences for our health care system will be profound. In view of the increase in life expectancy, and in order to keep medicine affordable in the future, health policy activities in the areas of primary and secondary prevention and health promotion will be necessary to enable everyone to live longer in good health.
In order to achieve this goal, in addition to the continuous improvement of health conditions, the focus is shifting to broad population-based information campaigns against unhealthy lifestyles and the development of environmental medicine research. This also means that an ever-increasing proportion of the work will shift from treating existing conditions to preventive strategies and services.
As the largest organ of the body, the skin reflects the first signs of aging particularly clearly. Since ancient times, man wants not only to live longer, but also to look young and healthy. Maintaining and improving the quality of the skin is also a central, sometimes existential concern for many today. Against this background, this DERMATOLOGIE PRAXIS will discuss some causes of skin aging, the resulting consequences and some selected possibilities and limitations of treatment.
