study design

The Lifelines study follows over 167,000 participants over a 30-year period. Every five years, participants visit one of the Lifelines sites in the northern parts of the Netherlands for an examination. During this visit, several physical measurements are made and participants are asked to fill in questionnaires. In addition, participants are invited to complete a follow-up questionnaire once every 1.5 years. You can find an overview of the collected data and samples for children and adults here.

Go to the section on the structure of the Lifelines cohort study for more details.

All samples are safely stored under the right conditions in the state-of-the-art Lifelines Lifestore, an automated storage system. Even after many years of storage the biological samples can be used for scientific purposes.
