Objective To study the sleep quality of hypertensive patients with comorbid depression as well as its influence factors. Methods A total of 3 637 people diagnosed with hypertension during the Hebei provincial mental disease epidemiological survey in 2016 were selected as the research subjects. The American Diagnostic and Statistical Manual of Mental Disorders（DSM⁃4）AXIS Ⅰ Clinical Examination for Disorders（SCID⁃I） was used for the diagnosis of mental disorders，and the Pittsburgh Sleep Quality Index（PSQI）was used to evalu⁃ ate sleep quality. Results The incidence of poor sleep quality of the hypertensive patients with depression was significantly higher than that in the patients with hypertension alone（74.44% vs. 18.29%，P < 0.01），and the inci⁃ dence of poor sleep quality in the hypertensive patients with major depressive disorder（81.42%）and dysthymia （84.38%）was more prominent. The total score of PSQI and the scores of its dimensions in the hypertension patients with depression were higher than those in the patients with hypertension alone（P < 0.05）. The patients with both hypertension and depression went to bed earlier，slept longer，but their actual sleep time was shorter. Logistic regression analysis showed that female，low education level，low family income，long course of hyperten⁃ sion，positive family history of mental illness，depression were the risk factors affecting the sleep quality of patients with hypertension. Conclusion The incidence of poor sleep quality among hypertensive patients with depression， especially among those patients with major depressive disorder and dysthymia，is much higher than among those with hypertension alone. Comorbid depression is the most common cause of poor sleep quality.
