Key result
Poor sleep quality is not significantly associated with overall cardiovascular health status.
Why the study?
Cardiovascular correlates of sleep disorders have not been well investigated in underserved populations.
Is poor sleep quality associated with worse cardiovascular health metrics in stroke-free adults aged ≥40 years?

Poor sleep quality is significantly associated with worse cardiovascular risk factors, such as smoking, physical inactivity, and elevated blood glucose, in a rural Latin American population.
Poor sleep quality links to select CVH metrics in rural Ecuador; hypothesis-generating, needs prospective trials before practice implications.
OBJECTIVES: Cardiovascular correlates of sleep disorders have not been well investigated in underserved populations. The aim of this door-to-door survey was to evaluate the association between sleep quality and cardiovascular health status in persons aged ≥40 years living in a village that is representative of rural Ecuador. METHODS: All stroke-free Atahualpa residents aged ≥40 years were screened with a validated Spanish version of the Pittsburgh Sleep Quality Index and the seven cardiovascular health (CVH) metrics proposed by the American Heart Association to assess the CVH status. RESULTS: A total of 635 persons (mean age 59 ± 13 years; 58 % women) were identified. A poor sleep quality was present in 27 % of the subjects (95 % CI 24-31 %) and a poor cardiovascular health in 69 % (95 % CI 63-71 %). In a multivariate logistic regression model, a poor sleep quality was associated with some CVH metrics in the poor range, including smoking status (p = 0.026), physical activity (p = 0.01) and blood glucose levels (p = 0.036). CONCLUSIONS: A poor sleep quality may be linked to individual cardiovascular risk factors in this underserved Latin American population. This finding provides useful insights for the implementation of regional prevention priorities.

Brutto et al. (2014) conducted a cross-sectional in Cardiovascular Health (n=635). Poor sleep quality vs. Good sleep quality was evaluated on Poor cardiovascular health (CVH) status (OR 1.26, 95% CI 0.86-1.86, p=0.233). Poor sleep quality was not significantly associated with overall poor cardiovascular health status (OR 1.26), but was linked to individual poor metrics including physical activity and blood glucose.
