Abstract

The morning chronotype is associated with a higher prevalence of arterial hypertension, dyslipidemia, diabetes mellitus, and cardiovascular disease compared to the evening chronotype.

  • Participants under 60 years old with a morning chronotype had a higher prevalence of cardiometabolic comorbidities.
  • No significant age-related effects were found for depression, which was more frequent among individuals with an evening chronotype.
  • The findings suggest that chronotype may serve as a potential clinical marker for identifying comorbidity risk in patients with obstructive sleep apnoea.
