The association of childhood HDL cholesterol with atherosclerotic cardiovascular disease events in adults: findings from the International Childhood Cardiovascular Cohort Consortium
- Prospective cohort study
- multicohort consortium (i3C)
Authors' conclusion
Childhood and adolescent HDL-C were prospectively and inversely associated with adult ASCVD, suggesting that low HDL-C could be a risk marker of adult ASCVD.
Study context
- Population
- Children in the International Childhood Cardiovascular Cohort (i3C) Consortium with childhood HDL-C and adult atherosclerotic cardiovascular disease (ASCVD) follow-up779 ASCVD + 784 imputed events
- Participants
- 38,589 children
- Exposure
- Childhood HDL-C levels and trajectories vs adult ASCVD
- Outcome
- Adult ASCVD events:
- Self-reports adjudicated by medical records
- Death registries

- Higher HDL-C z-scores in childhood, early childhood and adolescence associated with lower adult ASCVD risk (HR)
