Objectives:
Antidepressants are among the most prescribed medications in older adults. In this study we aimed to explore the trends in the use of antidepressants in older Swedish adults between 2006 and 2020.
Methods:We conducted a retrospective repeated cross-sectional study, where we included all older adults (65 years and older) registered in the Swedish National Prescribed Drug Register between 2006 and 2020. We estimated the use of antidepressants in older people for each year, across the 21 Swedish regions.
Results:The Swedish population of older adults increased from 1.2 million in 2006 to 1.7 million in 2020. There was an increase in antidepressant use from 12.4% in 2006 to 13.2% in 2019 and 13.8% in 2020. We found that the use of antidepressants varied across age groups, older adults 85+ had a higher use (18.2% in 2006, 18.2% in 2019 and 19.4% in 2020) compared to those 65-74 years of age (9.6% in 2006, 11.7% in 2019 and 12.2% in 2020).
Individuals who used antidepressants were generally older (mean age = 77.7) and more often women, compared to individuals who did not use antidepressants (mean age =75.7). Moreover, individuals who used antidepressants also had a higher use of benzodiazepine compared to non-users (25.1% vs. 6.4% in 2006; 16.0% vs. 2.7% in 2019 and 15.6% vs. 2.5% in 2020), sleeping drugs (27.7% vs. 10.9% in 2006; 25.2% vs. 9.3% in 2019 and 24.6% vs. 8.9% in 2020), first generation antipsychotics (1.1% vs. 4.0% in 2006 and 0.3% vs. 1.3% in 2020) and second-generation antipsychotics (1.0% vs. 6.3% in 2006 and 0.8% vs. 6.3% in 2020).
Citalopram was the most frequently used antidepressant. However, its use declined from 2006 to 2020 and instead we observed an increase in the use of mirtazapine and sertraline. The prescription of tricyclic antidepressants (TCA), selective monoamine-A inhibitors and lithium was relative stable over time.
Overall, antidepressants were prescribed at doses close to the defined daily doses (DDD), except for TCA, mianserin, bupropion and venlafaxine which were often prescribed at lower doses.
Conclusions:We found a slight increase in antidepressant prescription in Sweden between 2006 and 2020, with older adults 85 years and older using more antidepressants compared to those 65-74 years of age. Use of antidepressants was associated with increased use of benzodiazepines, sleeping drugs (zolpidem and zopiclone), as well as first- and second-generation antipsychotics. Citalopram was the most prescribed antidepressant, but its use has declined over time.

Background
Depression and overweight are each associated with abnormal immune system activation. We sought to disentangle the extent to which depressive symptoms and overweight status contributed to increased inflammation and abnormal cortisol levels.
MethodsParticipants were recruited through the Wellcome Trust NIMA Consortium. The sample of 216 participants consisted of 69 overweight patients with depression; 35 overweight controls; 55 normal-weight patients with depression and 57 normal-weight controls. Peripheral inflammation was measured as high-sensitivity C-Reactive Protein (hsCRP) in serum. Salivary cortisol was collected at multiple points throughout the day to measure cortisol awakening response and diurnal cortisol levels.
ResultsOverweight patients with depression had significantly higher hsCRP compared with overweight controls (p = 0.042), normal-weight depressed patients (p < 0.001) and normal-weight controls (p < 0.001), after controlling for age and gender. Multivariable logistic regression showed that comorbid depression and overweight significantly increased the risk of clinically elevated hsCRP levels ⩾3 mg/L (OR 2.44, 1.28–3.94). In a separate multivariable logistic regression model, overweight status contributed most to the risk of having hsCRP levels ⩾3 mg/L (OR 1.52, 0.7–2.41), while depression also contributed a significant risk (OR 1.09, 0.27–2). There were no significant differences between groups in cortisol awakening response and diurnal cortisol levels.
ConclusionComorbid depression and overweight status are associated with increased hsCRP, and the coexistence of these conditions amplified the risk of clinically elevated hsCRP levels. Overweight status contributed most to the risk of clinically elevated hsCRP levels, but depression also contributed to a significant risk. We observed no differences in cortisol levels between groups.
