Abstract
OBJECTIVES: To examine the association between sleep duration on workdays or non-workdays and unsatisfactory blood pressure (BP) control in Southern China. METHODS: We analyzed 4370 hypertensive patients, including their self-reported sleep duration on workdays or non-workdays and their BP. Unsatisfactory BP control was defined as systolic BP of ≥140 mm Hg or diastolic BP of ≥90 mm Hg. Multivariate logistic regression analyses were performed to evaluate the association between sleep duration and unsatisfactory BP control. RESULTS: Overall, the multivariable-adjusted odds ratios of unsatisfactory BP control risk were 1.59 (95% confidence interval, 1.14-2.22) for 9-10 hours of sleep on workdays and 1.47 (95% confidence interval, 1.07-2.03) for ≥10 hours of sleep on non-workdays compared with a sleep duration of 5-9 hours. No association between a short sleep duration and unsatisfactory BP control was noted. The association between a longer sleep duration (≥10 hours) and unsatisfactory BP control was more pronounced among women aged 65-70 years, with a body mass index ≥ 24 kg/m2. CONCLUSION: People with hypertension who slept 9-10 hours on workdays and ≥10 hours on non-workdays were more likely to have unsatisfactory BP control compared with those with a sleep duration of 5-9 hours; these associations tended to vary by age, sex, and body mass index. These findings indicate that a longer sleep duration might be a way to predict uncontrolled BP in hypertensive adults.
