New Lifelines dataset available


As of July 5, the first set of data from the second assessment has been included in the Lifelines catalogue. An extensive amount of longitudinal data has been released, containing both measurement and self-reported data of the second wave of more than 100,000 Lifelines adult participants. In addition, all baseline data from children is now available. Feel free to browse our catalogue to explore the potential of this new data for your own research.

Number of participants three data releases

The number of participants has remained fairly equal. However, the content of the dataset has been updated and broadened. The dataset now includes for example all baseline self-reported children data on behavior and health, measurement data from the second assessment from both adults and children (e.g. lung function, ECG and blood pressure) and new ISCO codes of occupations.

What’s next?

Part of the Lifelines participants have not participated in the second assessment of Lifelines yet. They will visit Lifelines in 2017 and will also fill out the questionnaires belonging to the second assessment. In addition, another questionnaire, following the second assessment,  is ongoing.
