    Evening chronotype is associated with a 16% higher risk of cardiovascular disease compared to intermediate chronotype.

  • 2

    Approximately 75% of the cardiovascular risk linked to evening chronotype is mediated by lower attainment of AHA's Life’s Essential 8 metrics.

  • 3

    Participants with a definite evening chronotype showed a 79% higher prevalence of unfavorable LE8 scores than those with an intermediate chronotype.

  • 4

    Poorer LE8 scores were observed across six components, with nicotine exposure and inadequate sleep being the strongest associations.

    The study's limitations include potential misclassification of chronotype and a predominantly White, healthier participant cohort.
