Are ‘healthy cohorts’ real-world relevant? Comparing the National Child Development Study (NCDS) with the ONS Longitudinal Study (LS)
- This study compared the NCDS with the ONS LS – a ‘gold-standard’ national reference population.
- Participants from the most recent NCDS 55-year survey were mostly unrepresentative of age-matched LS respondents.
- Despite differences in sample characteristics, longitudinal associations were similar in the NCDS and LS samples.
