For Researchers

EXCEED is a longitudinal population-based cohort which facilitates the investigation of genetic, environmental and lifestyle-related determinants of a broad range of diseases and of multiple morbidity through data collected at baseline and via electronic healthcare record linkage. We are now also collecting COVID-19 data.

Participants have consented to follow-up for up to 25 years through electronic health records and additional bespoke data collection is planned.
