Association between sleep duration and brachial-ankle pulse wave velocity / 中华心血管病杂志

ABSTRACT

Objective@#To investigate the association between sleep duration and brachial-ankle pulse wave velocity (baPWV).@*Methods@#A cross-sectional study method was used to observe 38 604 employees of Kailuan Group who participated in the physical examination and the baPWV test from January 2010 to July 2018. The age was (51.6±11.1) years old. There were 72.4% (27 955/38 604) male participants. According to the sleep duration, subjects were divided into 5 groups including ≤ 5 hours group (3 762 cases),>5 hours and ≤6 hours group (9 585 cases),>6 hours and ≤7 hours group (12 604 cases), >7 hours and ≤8 hours group (11 921 cases) and >8 hours group (732 cases). Multivariate logistic regression model was used to analyze the association between sleep duration and the baPWV.@*Results@#The age was (51.6±11.1) years old. There were 72.4% (27 955/38 604) male participants. The prevalence of baPWV≥14 m/s in ≤ 5 hours group, >5 hours and ≤6 hours group, >6 hours and ≤7 hours group, >7 hours and ≤8 hours group, and >8 hours group was 63.5% (2 389/3 762), 58.9% (5 645/9 585), 55.0% (6 926/12 604), 53.3% (6 356/11 921) and 54.8% (401/732) respectively. After adjusting for confounding factors including age, gender, smoking, drinking, physical exercise, snoring, hypertension, diabetes mellitus, dyslipidemia, body mass index≥24 kg/m2, mean arterial pressure, heart rate, and C-reactive protein, the multivariate logistic regression analysis showed that the OR were 1.48 (95%CI 1.29-1.70, P<0.01) and 1.18 (95%CI 1.07-1.30, P<0.01) respectively for baPWV≥14 m/s in ≤ 5 hours and >5 hours and ≤6 hours group when compared with >7 hours and ≤ 8 hours group.@*Conclusion@#Short sleep duration is associated with elevated baPWV in mid-aged Chinese population.
