[A case-control study on depression and anxiety in hypertensive patients].

OBJECTIVE: To study the current situation of depression and anxiety from patients with hypertension as well as to provide reference for the development of control and prevention program. METHODS: Participants older than 35-year including both hypertensive patients and healthy controls were randomly selected in 2 communities of Pukou district in Nanjing through Health Behavior Survey. All the subjects were assessed by the Zung's self-rating depression scale (SDS) and the Zung's self-rating anxiety scale (SAS). RESULTS: Raw score and index score of SDS and SAS were both significantly (P < 0.01) greater in hypertensive patients than in healthy control group. The prevalence of depression of 17.9% and anxiety of 9.5% in patient group were found significantly higher than that in healthy control group as 11.5% and 4.3%. Data from logistic regression model analysis showed that depression and anxiety were possible risk factors of hypertension (OR = 1.677, 95% CI: 1.013-2.776; OR = 2.451, 95% CI: 1.228-4.894). There was a combined effect seen between depression and anxiety (OR = 5.238, 95% CI: 2.356-11.664) but interaction did not appear. CONCLUSION: Depression and anxiety were possibly associated with hypertension and more attention needs to be paid to the mental health situation of hypertensive patients in order to improve their quality of life.
