The link of depression, untreated hypertension, and diabetes with mortality in postmenopausal women: A cohort study

Objective: To explore the association of depression, as well as untreated hypertension or diabetes with all-cause death in community-based postmenopausal women in Beijing. Methods: A cohort of 863 community-based postmenopausal women with no history of cardiovascular heart disease (CHD), stroke, cancer, or dementia was investigated on 20 July-28 September 2009 at baseline. Depression was diagnosed using the 30-item Center for Epidemiologic Studies Depression (CES-D) scale with CES-D >= 11. Meanwhile, data on health behavior, physical comorbidity, and social support at baseline were collected. These individuals were followed up from 20 July to 30 August 2014. All-cause mortality and cause of death were surveyed. Results: After a median follow-up of 4.97 years, 120 subjects died of all-cause. Twenty-four died of stroke, 19 died of myocardial infarction, 21 died of cancer. The others died of aging, infection, and accident. Depression and untreated HP were significantly associated with all-cause mortality in Cox models after full adjustment for all of the potential confounders (Depression HR: 2.16, 95%CI: 1.35-3.46; Untreated hypertension HR: 1.84, 95%CI: 1.12-3.02). However, negative correlation of untreated diabetes on all-cause mortality was observed in this population (HR: 1.36, 95%CI: 0.75-2.49). When depression was co-existing with hypertension/diabetes, the HR for mortality elevated significantly (Depression co-existing with hypertension HR = 3.87, 95% CI: 2.07-7.23; Depression co-existing with diabetes HR = 5.02, 95% CI: 1.5-16.79). Conclusions: It is suggested we should take sufficient care of postmenopausal females with depression and control blood pressure and glucose more effectively.
