In a large prospective study, a graded higher risk of all-cause mortality and mortality from cardiovascular disease (CVD) and ischemic heart disease (IHD) emerged in adults with moderate to severe depressive symptoms, compared with those with no such symptoms.
Participants with mild depressive symptoms had a 35%-49% higher risk of all-cause and CVD mortality, respectively, while for those with moderate to severe depressive symptoms, the risk of all-cause, CVD, and IHD mortality was 62%, 79%, and 121% higher, respectively.
“This information highlights the importance for clinicians to identify patients with depressive symptoms and help them engage in treatment,” lead author Zefeng Zhang, MD, PhD, of the division for heart disease and stroke prevention at the U.S. Centers for Disease Control and Prevention, Atlanta, said in an interview.
The study appears in JAMA Network Open.
A nonclassic risk factor for CVD death
This graded positive association between depressive symptoms and CVD death was observed in data from the National Health and Nutrition Examination Survey 2005-2018, which were linked with the National Death Index through 2019 for adults aged 20 and older. Data analysis occurred from March 1 to May 26, 2023. According to the authors, their analyses extend findings from previous research by assessing these associations in a large, diverse, and nationally representative sample. Using more nuanced CVD-related causes of death, depressive symptoms emerged as a nontraditional risk factor for CVD mortality.
The study
In a total cohort of 23,694, about half male, mean overall age 44.7 years, prevalences of mild and moderate to severe depression were 14.9% and 7.2%, respectively, with depressive symptoms assessed by the nine-item Patient Health Questionnaire asking about symptoms over the past 2 weeks.
Adults with depression had significantly lower CV health scores in six of the American Heart Association Life’s Essential 8 metrics for heart health. For all-cause mortality, hazard ratios were 1.35 (95% confidence interval, 1.07-1.72) for mild depressive symptoms vs. none and 1.62 (95% CI, 1.24-2.12) for moderate to severe depressive symptoms vs. none.
The corresponding hazard ratios were 1.49 (95% CI, 1.11-2.0) and 1.79 (95% CI,1.22-2.62) for CVD mortality and 0.96 (95% CI, 0.58-1.60) and 2.21 (95% CI, 1.24-3.91) for IHD death, with associations largely consistent across subgroups.
At the highest severity of depressive symptoms (almost daily for past 2 weeks), feeling tired or having little energy, poor appetite or overeating, and having little interest in doing things were significantly associated with all-cause and CVD mortality after adjusting for potential confounders.
Approximately 11%-16% of the positive associations could be explained by lifestyle factors such as excess alcohol consumption, overeating, and inactivity as per the AHA’s Life’s Essential 8 metrics.
“Taken together with the body of literature on associations between depression and CVD mortality, these findings can support public health efforts to develop a comprehensive, nationwide strategy to improve well-being, including both mental and cardiovascular health,” Dr. Zhang and associates wrote.
This research was funded by the U.S. Centers for Disease Control and Prevention. The authors had no conflicts of interest to disclose.
