Changes in depressive symptoms of older adults in the Czech Republic

It is unclear whether the rising burden of depression is due to its increasing prevalence or better detection. We aimed to study trends in depressive symptoms in older individuals from the Czech Republic.

We used data from the Survey on Health, Aging and Retirement in Europe. Depressive symptoms, defined by 4 or more points on the EURO-D scale, alone or in combination with pharmacological treatment, were compared between participants in 2006/2007 (cohort 1) and in 2015 (cohort 2). Binary logistic regression assessed the association of cohort 2 with depressive symptoms, step-wise adjusting for sociodemographic and clinical covariates.

The prevalence of depressive symptoms (defined by EURO-D) was 28% in cohort 1 and 22% in cohort 2 (p < 0.001). Cohort 2 was associated with lower odds of depressive symptoms, adjusting for all covariates (OR 0.77; 95% CI 0.63-0.94). Defined by EURO-D scale or pharmacological treatment, the prevalence was 30% in cohort 1 and 26% in cohort 2 (p < 0.001). Cohort 2 was associated with lower odds of depressive symptoms, adjusting for age and sex, but not in the fully adjusted model (OR 0.88; 95% CI 0.73-1.07). The difference in depressive symptoms between cohorts was associated in particular with increased length of education and higher household net worth.

Information about pharmacological treatment has been reported inaccurately.

The prevalence of depressive symptoms has decreased in older adults in the Czech Republic. Additional increase in education and socioeconomic resources of the population could further reduce the depressive symptoms in the population.
