Metabolic abnormalities in adult and geriatric major depression with and without comorbid dementia.
Metabolic abnormalities and metabolic syndrome (MetS) increasingly have been linked to depression. The authors studied examined inpatients 35 years and older with major depressive disorder (MDD) to determine the prevalence of component metabolic abnormalities and the full MetS with age, treatment, and comorbid dementia. Data analysis involved retrospective cross-sectional review from a nonprofit psychiatry inpatient service of all discharges 35 years and older with a diagnosis of MDD during a 3 year period (April 1, 2003 to March 31, 2006) (N=1718). Metabolic measures included waist circumference, lipid measurements, glucose, and hypertension diagnosis. Abnormal metabolic measures and MetS were highly prevalent in both young and old patients with MDD: one or more component was present in 87.6% of older (65-99 years old) and 79.9% of younger patients. Full MetS was present in 31.5% of older and 28.9% of younger patients (not significant, P=0.85). Metabolic abnormalities were not associated with atypical antipsychotics after controlling other variables. One-quarter (n=79, 24.9%) of older inpatients had a dementia co-diagnosis. Older patients with MDD and dementia had greater risk of elevated glucose while younger patients were more often hypertensive. Longitudinal studies are needed to determine the relationships of MDD with or without dementia with these highly prevalent abnormal metabolic measures and MetS.
