Evening Chronotype Linked to Cardiovascular Risk
Researchers examine the association between evening chronotype and cardiovascular disease risk, identifying Life’s Essential 8 cardiovascular health metrics as a key mediator.
To investigate the association between evening chronotype and cardiovascular disease risk, particularly focusing on the mediating role of the American Heart Association’s Life’s Essential 8 health metrics.
Key Findings:
Adults with a definite evening chronotype had a 16% higher risk of cardiovascular disease compared to those with an intermediate chronotype.
Approximately 75% of the association between evening chronotype and cardiovascular disease risk was mediated by lower LE8 scores, with nicotine exposure being the largest mediator.
Participants with a definite evening chronotype had a 79% higher prevalence of unfavorable LE8 scores.
Interpretation:
The findings suggest that evening chronotype is associated with increased cardiovascular disease risk primarily due to poorer cardiovascular health metrics, particularly in relation to specific LE8 components.
Limitations:
Chronotype was assessed using a single self-reported item, which may introduce misclassification.
LE8 components were assessed concurrently with chronotype, limiting temporal sequencing.
The cohort is predominantly White and healthier, affecting generalizability, and residual confounding could not be fully excluded.
Conclusion:
The study highlights the importance of chronotype in cardiovascular health, suggesting that targeted lifestyle interventions could mitigate risks associated with evening chronotype.
