Arterial stiffness

 

Arterial Stiffness Is Not Independently Associated With Nighttime Sleep Duration In Community-Dwelling Older Adults. Results From The Atahualpa Project. La Rigidez Arterial no se Encuentra Asociada con la Duración del Sueño Nocturno en Adultos Añosos Que Viven en la Comunidad. Resultados del Proyecto Atahualpa.

Objectives: We aimed to assess the association between arterial stiffness and nighttime sleep duration in community-dwelling older adults living in rural Ecuador.

Methods: Aortic pulse wave velocity (PWV) determinations were used to assess arterial stiffness. Nighttime sleep duration was assessed by a single question. A generalized linear model—adjusted for demographics, cardiovascular risk factors and psychological distress—was fitted to assess the independent association between the aortic PWV and nighttime sleep duration (dependent variable).

Results: A total of 303 individuals were enrolled. Univariate analysis showed a significant association between the aortic PWV and long sleep duration (p=0.034), which vanished in a multivariate linear model (p=0.524). The single covariable remaining significant was anxiety (p=0.013).

Conclusion: Lack of independent association between arterial stiffness and nighttime sleep duration might be more likely related to lack of reliability of evaluation of sleep duration by means of a single question.
