RELATIONSHIP BETWEEN SLEEP DURATION AND BLOOD PRESSURE IN HOSPITALIZED PATIENTS

Abstract

Objective: To identify the relationship between sleep and blood pressure in hospitalized patients. Material
and Method: A quantitative, descriptive and correlational cross-sectional study, the unit of analysis were hospitalized patients from two public hospitals in the state of Tamaulipas, Mexico; the sample was non- probabilistic by convenience and consisted of 119 patients. The measurement modality was by interview technique using a questionnaire on sociodemographic data, blood pressure measurement and the Pittsburgh Sleep Quality Index instrument; data collection was completed in July 2022; for statistical analysis, measures of central tendency were used, for differences Mann-Whitney U test and Kruskal-Wallis H test, and correlation was applied with Spearman’s Rho coefficient. Results: Men presented elevated levels of DBP (p = .018) and
older adults had elevated levels of SBP (p = .016). It was reported that the patient’s time to bed (p= < .05 [SBP]) and time to wake up (p = < .01 [SBP, DBP]), as well as the number of hours slept (p = < .05 [DBP]) had a significant positive correlation with blood pressure. Conclusions: Decreases in sleep duration, bedtime, and wake time correlate with blood pressure in hospitalized patients.
