For 30 years (since 1987) tracks the health of a group of randomly selected adult Dutch inhabitants of Doetinchem from originally between 20-60 years. This provides a wealth of information of four generations: 20-29, 30-39, 40-49 and 50-60 year olds. The name of this study is the Doetinchem Cohort Study. Every five years the health and habits of the participants are examined at the local health department.

The purpose of the Doetinchem Cohort Study is to give insight into trends in lifestyle and health. So there will be more and more knowledge about why some people age without many problems, while others have health problems at an early age. The study collects data on:

  • Biological factors: blood pressure, cholesterol, (over) weight;
  • Several specific diseases: cardiovascular disease, asthma, COPD , diabetes, cancer, migraine, musculoskeletal;
