Spotlight on NSHD46
Participants in the UK’s longest-running birth cohort study are turning 80 this year.

The MRC National Survey of Health and Development (NSHD46) was established after WWII initially to investigate the costs associated with pregnancy. The study subsequently looked at socioeconomic and environmental impacts on morbidity, educational attainment and earnings. As the cohort gets older, the focus has shifted to investigating the processes of ageing using in-depth brain and heart phenotyping, and the use of health and social care services.

NSHD46 provides researchers with a wealth of opportunities to investigate how early and mid-life experiences may have an impact on health and wellbeing in later life. More information about the characteristics of NSHD46 and how to apply to access its data via UK LLC is available on Guidebook.
Research focus
For the last 18 years adults in England referred for NHS psychological treatment for anxiety, depression, and other common mental health conditions have had information about them, their symptoms, their treatment, and their outcomes routinely collected. This rich data resource – known as the IAPT (Improving Access to Psychological Therapies) dataset – has been linked with UK LLC’s partner LPS participants and is ripe for research!  

Rachel Latham, a Research Fellow at King’s College London, has worked with UK LLC to get the linked IAPT dataset ready to be used by researchers.

Read more about the research potential of the IAPT dataset.
Reminders for researchers
  • The UK LLC Data Team is here to help researchers work effectively in the UK LLC Trusted Research Environment (TRE). We have monthly online UK LLC User Group meetings and also offer 1:1 support sessions – see our user support guide.
  • You must not take any screenshots of data in the TRE. Even small outputs, such as a single number MUST be requested via the ‘data out’ process – see UK LLC’s guide to moving files in and out of the TRE.
  • UK LLC promotes a culture of reproducible and reusable research. You must therefore make your project workings (e.g. syntax/scripts, code lists) accessible to other users via your UK LLC project GitHub repository.
