Zusammenfassung: | Background
Individuals with depression and depressive symptoms have a higher mortality rate than non‐depressed individuals. The increased comorbidity and mortality associated with depression has remained largely unexplained. The underlying pathophysiological differences between depressive subtypes, melancholic and non‐melancholic, may provide some explanation to this phenomenon.
Methods
One thousand nine hundred and ninety five participants (mean age 61 years) from the Helsinki Birth Cohort Study were recruited for this prospective study and followed up for a mean of 14.1 years. Information regarding medical history, lifestyle, and biochemical parameters were obtained. Depressive symptoms were assessed using the Beck Depression Inventory. Standardized mortality ratios were calculated.
Results
Participants were followed up for a total of 28,044 person‐years. The melancholic depressive group had an increased adjusted risk of mortality [HR 1.49 (95% CI: 1.02–2.20)] when compared to the non‐depressive group. Comparing mortality to the whole population of Finland using standardized mortality ratios (SMR) both the non‐melancholic [1.11 (95% CI: 0.85–1.44)] and melancholic depressive [1.26 (95% CI: 0.87–1.81)] groups had higher mortality than the non‐depressive group [0.82 (95% CI: 0.73–0.93)].
Conclusions
Melancholic depressive symptoms are most strongly related to a higher mortality risk.
Highlights
Depression is associated with mortality.
Depressive symptoms based on BDI‐IA show an association with increased risk for mortality.
Specifically melancholic depressive symptoms present with increased risk for mortality. |
