Association between length of daily siesta and brachial-ankle pulse wave velocity (baPWV): a community-based cross sectional study in North China.

Abstract

To date, many studies have showna link between siesta andcardiovascular events. Little is known regarding the connection between siesta and brachial-ankle pulse wave velocity (baPWV) levels, even though baPWV can determinethe degree ofatherosclerosis and vascular stiffness. Thus, we examined the relationship between siestatime and baPWV in a cross-sectional study. Interviews, physical examinations, lab testing, and electron beam computed tomography were all part of the baseline evaluation forparticipants aged older than 35. Baseline data were compared for 3different siesta habits: irregular or no siestas, daily short siestas (1h or less), and daily long siestas (> 1h). Utilizing logistic regression models and multivariate linear regression, the link between siestatime and baPWV was determined. Among all 6566participants, the different siesta groups had a significant difference of the degrees of AS (P < 0.001). The same outcome was true for both males (P < 0.001) and females (P < 0.001). Numerous cardiovascular risk variables and markers of subclinical atherosclerosis were positively correlated with daily extended siestas. Results from thefully adjusted model showed that long siestas (> 60min, OR = 1.18, 95%CI: 1.06-1.31, P = 0.002) were linked to a more severe level of the baPWV. For age or gender stratification, we found significant differences between non-siesta and > 60min siesta groups. Multiple linear regression analysis revealed a positive connection between siesta duration and baPWV (β = 0.197, P = 0.038). An elevated risk of atherosclerosis was shown to accompany prolonged siestas. These results need to be followed up on with prospective studies and additional lab work.
