Relation between sleep duration and brachial-ankle pulse wave velocity in patients with type 2 diabetes mellitus / 中华内分泌代谢杂志

ABSTRACT

To explore the relationship between sleep duration and brachial-ankle pulse wave velocity(baPWV) in patients with type 2 diabetes mellitus(T2DM). A total of 1 755 patients with T2DM received standardized management of metabolic disease from March 1, 2018 to February 29, 2020 were included. All patients were classified into three groups according to the sleep duration: short(≤6 h), medium(>6 h to 8 h) and long(>8 h). Increased arterial stiffness was defined as baPWV≥1 600 cm/s. The prevalence of baPWV≥1 600 cm/s was 39.7%, 30.8% and 38.6% in short, medium and long sleep duration group, respectively( P<0.01). Multivariate logistic regression analysis showed that patients with long sleep duration( OR=1.317, P<0.05) but not short sleep duration( OR=1.169, P>0.05) had a higher risk for baPWV≥1 600 cm/s compared with the reference group with medium sleep duration. Stratified analyses by sex showed that the OR were 1.735( P<0.05) among female and 1.131( P>0.05) among male respectively for baPWV≥1 600 cm/s in long sleep duration group when compared with medium sleep duration group. Sleep duration>8 h was found to be associated with elevated baPWV in patients with T2DM. There were gender differences in the correlation between long sleep duration and baPWV.
