Abstract
DEL BRUTTO, Oscar H. et al. Arterial Stiffness Is Not Independently Associated With Nighttime Sleep Duration In Community-Dwelling Older Adults. Results From The Atahualpa Project. Rev Ecuat Neurol [online]. 2019, vol.28, n.2, pp.19-22. ISSN 2631-2581.
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.
