Prevalence of poor sleep quality and its associated factors among hypertensive patients on follow up at Jimma University Medical Center

Abstract

Several studies have reported an association between the abnormal duration of sleep and chronic conditions including hypertension. However, the existing body of evidence is not entirely significant; as insignificant associations between poor sleep and blood pressure (BP) have been found across differentstudies. The aim of this study was to determine prevalence and factors associated with poor sleep quality among hypertensive patients in Jimma University Medical Center. An institution based cross sectional study design was employed from June 01 to July 15, 2018 among 279 hypertensive patientson follow-up at Jimma University Medical Centre chronic clinic, Jimma, Ethiopia. Data collection was done by using face to face interview. Sleep quality was measured by using validated, standard Pittsburgh sleep quality index (PSQI). PSQI total score ≥5 was considered as a diagnostic of poor sleep quality. On multivariate logistic regression variables with of p value of <0.05 was considered as predictors of poor sleep quality. A total of 279 hypertensive patients were enrolled into the study. Out of which 279, 142 (50.9%) were males. The prevalence of poor sleep quality among hypertensive patient was 99 (35.5%). Physical inactivity (AOR = 0.288, 95% CI: (0.130-0.639), diastolic blood pressure Stage I (AOR = 3.923, 95% CI: 1.052-14.632) and diastolic blood pressure Stage II (AOR = 4.520; 95% CI: 1.079-18.931) were identified as independent predictors of poor sleep quality. In conclusion, about one-third of hypertensive patients were poor sleepers. High diastolic blood pressure and physical inactivity are independent predictors of poor sleep quality among hypertensive patients.
