Abstract

Abstract : Sleep disorders have been shown to increase the risk of hypertension, while the relationship between night sleep latency and hypertension is less well-known. We aimed to investigate the association between night sleep latency and hypertension, as well as related sleep factors by gender in the Chinese population. We conducted a cross-sectional study of the relationship between night sleep latency and hypertension. The sample size included 619 consecutive hospitalized patients (M/F: 302/317, 64.01 ± 12.27 years). T test, Chi-square test, and ANOVA were performed to analyze baseline data and intergroup comparisons. Spearman correlation analysis was performed to find the interrelationships. Multivariate logistic regression analysis was performed to adjust for covariables. The findings showed hypertension patients had longer night sleep latency ( P < .001). After adjusting for confounding factors, night sleep latency was positively correlated with hypertension in both men and women (odds ratio: 1.065, 95% confidence interval: 1.044–1.087). Spearman correlation analysis suggested that night sleep latency was positively correlated with systolic blood pressure ( r = 0.186, P < .001), diastolic blood pressure ( r = 0.136, P < .001), sleep initiation time ( r = 0.091, P = .023), and global Pittsburg Sleep Quality Index score ( r = 0.371, P < .001), was negatively correlated with sleep duration ( r = −0.186, P < .001), sleep time on weekdays ( r = −0.183, P < .001), and sleep time on weekends ( r = −0.179, P < .001). Longer night sleep latency was associated with an increased risk of hypertension in men and women, which might involve the pathological progression of hypertension along with other sleep factors.
