The Relationship Between Depression and Metabolic Syndrome in the Elderly Population: the Cohort Aging Study

Objective: metabolic syndrome (mets) and depression are two important causes of disability in the elderly. the association between mets and depressive symptoms in iranian elderly is unclear. in this populationbased study, we aimed at evaluating the relationship between mets and its components with depression in iranian elderly population. method: this cross sectional study was derived from amirkola health and ageing project (ahap).the participants of this study included 1560 elders over the age of 60 during 2012 and 2013. mets was diagnosed based on adult treatment panel iii report and depressive symptoms according to geriatric depression scale. odds ratio (or) and 95% confidence interval (ci) based on age and gender were estimated using regression logistic model. results: depressive symptoms were observed in 28.7% of men and 46.2% of women. age and genderadjusted or of depressive symptoms did not show a significant difference among the participants with or without mets. a significant association between mets components (including waist circumference, hdlc, fasting blood glucose, triglyceride) and depressive symptoms was observed, but this association no longer existed after age and gender adjustment. elevated blood pressure revealed a significant relationship with depressive symptoms in men only (or, 0.665; 95% ci, 0.4690.943). conclusion: depressive symptoms were associated with blood pressure component but not mets in the elderly population of amirkola, iran. this association highlights the relevance of norepinephrine signal and sympathetic nervous activity disturbance for the emergence of depressive symptoms in the elderly. therefore, it is reasonable to consider depression in hypertensive patients, especially in men.
