Time-Varying Depressive Symptoms and Cardiovascular and All-Cause Mortality: Does the Risk Vary by Age or Sex?

ABSTRACT: Background Depressive symptoms are associated with mortality. Data regarding moderation of this effect by age and sex are inconsistent, however. We aimed to identify whether age and sex modify the association between depressive symptoms and all-cause and cardiovascular disease (CVD) mortality. Methods and Results The REGARDS (Reasons for Geographic and Racial Differences in Stroke) study is a prospective cohort of Black and White individuals recruited between 2003 and 2007. Associations between time-varying depressive symptoms (Center for Epidemiologic Studies Depression scale score ?4 versus <4) and all-cause and CVD mortality were measured using Cox proportional hazard models adjusting for demographic and clinical risk factors. All results were stratified by age or sex and by self-reported health status. Of 29 491 participants, 3253 (11%) had baseline elevated depressive symptoms. Mean age was 65 (9.4) years, with 55.1% of participants female, 41.1% Black, and 46.4% had excellent/very good health. Depressive symptoms were measured at baseline, on average 4.9 (SD, 1.5), then 2.1 (SD, 0.4) years later. Neither age nor sex moderated the association between elevated time-varying depressive symptoms and all-cause or CVD mortality (all-cause: age 45-64 years adjusted hazard ratio [aHR], 1.38; 95% CI, 1.18-1.61 versus age ?65 years aHR,1.36; 95% CI, 1.23-1.50; P=0.05; CVD: age 45-64 years aHR, 1.17; 95% CI, 0.90-1.53 versus age ?65 years aHR, 1.26; 95% CI, 1.06-1.50; P=0.54; all-cause: males aHR, 1.46; 95% CI, 1.29-1.64 versus female aHR, 1.34; 95% CI, 1.19-1.50; P=0.35; CVD: male aHR, 1.32; 95% CI, 1.08-1.62 versus female aHR, 1.22; 95% CI, 1.00-1.47; P=0.64). Similar results were observed when stratified by self-reported health status. Conclusions Depressive symptoms confer mortality risk regardless of age and sex, including individuals who report excellent/very good health.

Project description:IntroductionDepression is common but underrecognized in patients with chronic kidney disease (CKD), especially among racial/ethnic minorities. We examined the association between depressive symptoms and all-cause mortality (including deaths before and after end-stage renal disease [ESRD]) and whether antidepressant use impacts this association, overall, and by race/ethnicity.MethodsWe ascertained whether the presence of depressive symptoms, defined by a Beck Depression Inventory II (BDI) score of >14 at cohort enrollment, was associated with all-cause mortality (before or after ESRD) among study participants of the Chronic Renal Insufficient Cohort (CRIC) overall and by race/ethnicity. Models were adjusted for socioeconomic factors, baseline CKD severity, time-updated comorbid conditions, and time-updated antidepressant use. Confirmatory analyses were performed among African American Study of Kidney Disease and Hypertension (AASK) participants.ResultsAmong 3739 CRIC participants, 16.3% had a baseline BDI of >14; 18.2% reported antidepressant use. Crude mortality rate was 3.16 per 100 person-years during 6.8 years of median follow-up. Baseline BDI >14 was independently associated with higher risk of all-cause mortality (adjusted hazard ratio [aHR]: 1.27; 95% confidence interval: 1.07-1.52) without attenuation by antidepressant use. Differences among white and black individuals were noted (Pinteraction= 0.02) but not among white versus Hispanic individuals (Pinteraction = 0.43) or black versus Hispanic individuals (Pinteraction = 0.22). Depressive symptoms were associated with higher mortality among white individuals (aHR: 1.66; 1.21-2.28), but not Hispanic individuals (aHR: 1.47; 0.95-2.28) or black individuals (aHR: 1.06; 0.82-1.37). Similar results were noted among 611 AASK participants (aHR: 0.99; 0.69-1.42).ConclusionsThe presence of depressive symptoms is a risk factor for all-cause mortality among patients with mild-moderate CKD, particularly among white individuals. Further studies are needed to understand the heterogeneity in the response to the presence of depressive symptoms by race.
