Key result
Long night sleep duration (≥9 hours) was associated with a 48% increased odds of arterial stiffness compared to 7 hours of sleep.
Why the study?
The study was conducted to examine the relationship between self-reported sleep duration and arterial stiffness in a large Chinese population from Kailuan.

Effect estimate: OR 1.48 (95% CI 1.05-2.08)
Absolute Event Rate: 54.7% vs 50.7%
Long night sleep duration (≥9 hours) is independently associated with an increased risk of arterial stiffness in a general Chinese population.
Long sleep duration should not yet change practice for arterial stiffness; leaves open causal confirmation in prospective studies.
To examine the relationship between self-reported sleep duration and arterial stiffness in a large Chinese population from Kailuan.From July 2010 to December 2015, a total of 17,018 participants aged 18 to 98 years were enrolled after excluding those with a history of cerebrovascular events and coronary artery disease. Participants were divided into 5 categories according to self-reported night sleep duration: ≤5.0, 6.0, 7 (ref), 8, and ≥9.0 hours. A brachial-ankle pulse wave velocity ≥1400 cm/s was considered to represent arterial stiffness. Multivariate logistic regression models were used to calculate the odds ratio (OR) and confidence interval (CI) for arterial stiffness according to the sleep duration.Using 7 hours of sleep as the reference group, the multivariable adjusted ORs (95% CI) for arterial stiffness were 1.00 (0.87-1.16), 1.00 (0.90-1.11), 1.0 (ref), 1.03 (0.93-1.14), and 1.48 (1.05-2.08) from the lowest to highest category of sleep duration, respectively. Secondary analysis showed no evidence of interactions between sleep duration and age/sex on the risk of arterial stiffness (P-interaction = .390/.198).A long night sleep duration was associated with increased arterial stiffness.

Liu et al. (2020) conducted a cross-sectional in Arterial stiffness (n=17,018). Long sleep duration (≥9 hours) vs. 7 hours of sleep was evaluated on Arterial stiffness (brachial-ankle pulse wave velocity ≥1400 cm/s) (OR 1.48, 95% CI 1.05-2.08). Long night sleep duration (≥9 hours) was associated with a 48% increased odds of arterial stiffness compared to 7 hours of sleep.
