UK Longitudinal Linkage Collaboration

NSHD is one of many UK longitudinal research studies contributing to the Longitudinal Health & Wellbeing National Core Study for COVID-19 research. This has been designed by the UK’s top scientists to allow longitudinal studies – such as NSHD - to fully contribute to the national research programme and policy development. To do this, many studies need to put their COVID-19 relevant data into a single secure research environment to build scale and numbers across diverse population groups, occupations and other factors associated with COVID-19 risk, and from all over the UK. It is also necessary to link these participants to their health and wellbeing, administrative and environmental records to follow changes in status  (e.g. who has had COVID-19, who has been vaccinated during the pandemic and as we return to normal. This research programme looks at the big picture which includes COVID-19 itself, but also the impact that lockdown and other restrictions have had on wider health (such as mental health, or cancer care and other ongoing health needs), education and families. For those of you who have taken part in the ZOE Symptom Study ( it will also be useful to link to those records to get a detailed record of symptoms and the impact of COVID-19, this may help us understand outcomes such as Long COVID.

To achieve this the Longitudinal Health & Wellbeing National Core Study is establishing the UK Longitudinal Linkage Collaboration (UK LLC).
