... lity were used as the independent variable (X) for multiple line regression analysis (Stepwise) to evaluate the correlation between sleep quality and life quality.Results: The results of group comparison showed that the total PSQI score was significant at people's residence (P<0.01). Correlation analysis indicated that subjective sleep quality, sleep disturbance, daytime dysfunction, age, concomitant diseases, and years of diagnosed hypertension had a significant association with the PCS scores (P<0.05 for all). Subjective sleep quality, sleep disturbance, daytime dysfunction, and monthly income had a significant association with the MCS scores (P<0.05 for all).

Considering the close relation among hypertension, sleep quality, and life quality, possible interventions like sleep hygiene was appealed to relieve hypertensive symptoms, promote sleep quality, and increase life quality.Trial registration: 2018-1602000-03-02
