Recent research analyzed UK Biobank participants and found that a definite evening chronotype is linked to a 16% higher risk of cardiovascular disease (CVD), primarily mediated by a lower achievement of the American Heart Association's Life's Essential 8 (LE8) health metrics. The study highlighted nicotine exposure, sleep deprivation, and poor dietary habits as significant contributors affecting LE8 scores. With a cohort of 322,777 adults followed for nearly 14 years, the findings raise concerns about the cardiovascular health of those with evening preferences based on their lifestyle choices.
1. Evening chronotype linked to 16% higher CVD risk. 2. Poor LE8 scores mediate the risk. 3. Participants: 322,777 adults (ages 39-74). 4. LE8 components include sleep, diet, nicotine. 5. Long-term follow-up of 13.8 years. 6. Limitations include potential misclassification and generalizability issues. 7. Findings underscore the connection between lifestyle and cardiovascular health.
