Multivariable logistic regression was used to analyze the association between habitual sleep duration and BP control. Habitual sleep duration was self-reported and defined as the amount of sleep usually obtained in a night or main sleep period during weekdays or workdays. It was categorized as < 6, 6 - < 7, 7– 9, and > 9 hours. BP control was defined as average systolic BP < 130mmHg and diastolic BP < 80mmHg.Results: Results from the fully adjusted models show that among all adults with hypertension, habitual sleep duration of < 6 hours night/main sleep period was associated with reduced odds of BP control (OR = 0.53, 95% CI: 0ss.37– 0.76, P = 0.001) when compared to 7– 9 hours. In the subpopulation of adults who were on antihypertensive medication, those with a sleep duration of < 6 hours had lower odds of BP control than those with a sleep duration of 7– 9 hours (OR = 0.53, 95% CI: 0.36– 0.77, P = 0.002). No significant differences were noted in all adults with hypertension and in the subpopulation of those on antihypertensive medication in BP control between the reference sleep duration group (7– 9 hours) and the 6 - < 7 or > 9 hours groups. There were no significant differences across age groups or gender in the relationship between habitual sleep duration and BP control.Conclusion: Sleep duration of < 6 hours is associated with reduced odds of hypertension control. These significant findings indicate that interventions to support adequate habitual sleep duration may be a promising addition to the current hypertension management guidelines.Keywords: hypertension, blood pressure control, hypertension control, sleep, sleep duration |
