Is uncontrolled hypertension related to sleep quality and circadian rhythm?

ABSTRACT

Background

This study investigated the relationship between sleep quality and circadian rhythm chronotype with uncontrolled hypertension.

Methods

This cross-sectional study was conducted on 170 patients. Sleep quality is classified into two groups: good sleep quality and poor sleep quality. Circadian rhythm has three chronotypes: morning, intermediate, and evening.  

Results

Of a total of 170 patients, 84 (49.4%) patients were male. The total mean age was 62.8 (±12). The Uncontrolled hypertension odds ratio in patients with poor sleep quality was 18.47 (CI= (5.1, 67); P-value = 0.001). Patients with intermediate rhythms were more likely to have uncontrolled hypertension (OR:4.18, CI= (1.7, 10.5); P-value = 0.002). In the multiple logistic regression model, male gender increased the odds of uncontrolled hypertension in patients with poor sleep quality or intermediate circadian rhythm (OR: 17, CI;(3.7, 78.9); OR:6.83, CI:(2.3, 20.3) respectively).    

Conclusion

Poor sleep quality and intermedia circadian rhythm were related to uncontrolled hypertension..
