Abstract

Background: Blood pressure variability (BPV) has been reported to be a predictor of cardiovascular and some cognitive diseases. However, the association between napping and BPV remains unknown. This study aimed to explore the association between napping and BPV.<br />Materials and Methods: A cross-sectional study including 105 university students was conducted. Participants' 24 h ambulatory blood pressure monitoring (24 h ABPM) were measured, and napping behaviors were investigated. BPV were measured by the 24 h ABPM, included standard deviation (SD), coefficient of variation (CV), and average real variability (ARV).<br />Results: Among the participants, 61.9% reported daytime napping. We found that nap duration was significantly associated with daytime CV of diastolic blood pressure (DBP) ( r  = 0.250, P  = 0.010), nighttime CV of systolic blood pressure (SBP) ( r  = 0.217, P  = 0.026), 24 h WCV of DBP ( r  = 0.238, P  = 0.014), 24 h ARV of SBP ( r  = 0.246, P  = 0.011) and 24 h ARV of DBP ( r  = 0.291, P  = 0.003). Compared with the no napping group, 24 h WCV of DBP, daytime CV of DBP, and daytime SD of DBP were significantly higher in participants with napping duration >60 min. With multiple regression analysis we found that nap duration was an independent predictor for 24 h ARV of SBP ( β  = 0.859, 95% CI, 0.101-1.616, P  = 0.027) and 24 h ARV of DBP ( β  = 0.674, 95% CI, 0.173-1.175, P  = 0.009).<br />Conclusions: Napping durations are associated with BPV among university students. Especially those with napping durations >60 min had a significantly higher BPV than those non-nappers.<br />Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.<br /> (© 2023 Dai, Wu, Jiang, Tang, Tang, Meng, Huang, Gao, Li, Baker, Zheng and Yang.)
