SWICOS = Swiss Cohort Study

The prospective SWICOS study aims to investigate the health status, risk factors, and risk markers in a population-based Swiss cohort and follow them longitudinally. These data can help identify new (previously overlooked), actionable, promising, and cost-effective strategies for preventing chronic age-related diseases and implementing them at the population level. The increased life expectancy and the resulting profound changes in the demographics and lifestyle of the Swiss population require new approaches to reduce the various burdens of age-related diseases and to maintain optimal quality of life and health for as long as possible.

The objectives of the SWICOS study

The primary objective of the SWICOS study is to investigate the health status, with particular emphasis on cardiovascular health, and prospectively observe changes in the health status in a representative sample of the Swiss population over time. The SWICOS study aims to provide actionable answers to the question: How can chronic age-related diseases be better prevented or at least minimized?

Health problems

Identifying hidden or unrecognized health problems that increase the risk of chronic diseases (e.g., cardiovascular diseases, age-related diseases, dementia, etc.)


Identifying and determining barriers to accessing healthcare and implementing health-promoting measures.

Prevention strategies

Evaluating and optimizing the effectiveness of current prevention strategies and recommendations

Health programs

Evaluating and optimizing knowledge and attitudes towards ongoing health programs and public health recommendations.

Health goals

Optimizing the progress towards national health goals.

Prevention strategies

Incorporating new prevention strategies and recommendations from the SWICOS study into national prevention strategies.

Successful prevention

Formulating and implementing models for successful prevention of chronic diseases and healthy aging.
