Cardiovascular risk factors are associated with an increased risk of depression in older adults, according to a new study published April 13 in the open-access journal PLOS ONE by Sandra Martín-Peláez of University of Granada, Spain, and colleagues.

Cardiovascular disease and depression are thought to be closely related due to similar risk factors, including inflammation and oxidative stress. Although it has been shown that depression could be a risk factor for developing cardiovascular disease, studies analyzing the potential impact of cardiovascular health on developing depression are scarce.

In the new study, the researchers used data from an ongoing 6-year multi-center randomized trial in Spain which analyzes the effect of a Mediterranean Diet on men aged 55-75 and women aged 60-75 with overweight or obesity. 6,545 individuals with no cardiovascular or endocrine disease at baseline were included in the current analysis. A cardiovascular risk score according to the Framingham-based REGICOR function was calculated for each person, dividing participants into low (LR), medium (MR), or high/very high (HR) cardiovascular risk groups. Depressive status was gauged using a questionnaire at baseline and after 2 years of follow-up.

At baseline, women in the HR group showed higher odds of depressive status than LR women (OR 1.78 95% CI 1.26-2.50). In addition, among all participants with baseline total cholesterol below 160 mg/mL, MR and HR individuals showed higher odds of depression than LR (MR: OR 1.77 95% CI 1.13-2.77; HR: OR 2.83 95% CI 1.25-6.42). On the contrary, among participants with total cholesterol of 280 mg/mL or higher, MR and HR individuals had a lower risk of depression than LR (MR: OR 0.26 95% CI 0.07-0.98; HR: OR 0.23 95% CI 0.05-0.95). After two years, during which time all individuals were instructed to follow a Mediterranean Diet as part of the trial, participants, on average, decreased their depressive status score, with the greatest decreases seen for MR and HR participants with high baseline cholesterol levels.

The authors conclude that high and very high cardiovascular risk are associated with depressive symptoms, especially in women, and that the role of other factors, such as adherence to the Mediterranean Diet, deserves further research.

The authors add: “High cardiovascular risk, especially in women, is associated with symptoms of depression in the elderly.”

Funding: The PREDIMED-Plus trial was supported by the European Research Council through a grant to MAM (Advanced Research Grant 2013-2018; 340918). The project was also supported by the official funding agency for biomedical research of the Spanish Government (ISCIII) through the Fondo de Investigación para la Salud (FIS), which is co-funded by the European Regional Development Fund (four coordinated FIS projects), who awarded grants to JS and JV (PI13/00673, PI13/00492, PI13/00272, PI13/01123, PI13/00462, PI13/00233, PI13/02184, PI13/00728, PI13/01090, PI13/01056, PI14/01722, PI14/00636, PI14/00618, PI14/00696, PI14/01206, PI14/01919, PI14/00853, PI14/01374, PI16/00473, PI16/00662, PI16/01873, PI16/01094, PI16/00501, PI16/00533, PI16/00381, PI16/00366, PI16/01522, PI16/01120, PI17/00764, PI17/01183, PI17/00855, PI17/01347, PI17/00525, PI17/01827, PI17/00532, PI17/00215, PI17/01441, PI17/00508, PI17/01732 and PI17/00926). The International Nut&Dried Fruit Council - FESNAD - also provided funding through a grant to MAM (201302), and Recercaixa also awarded a grant to JS (2013ACUP00194). The Department of Health, Generalitat de Cataluña by the calls “Acció instrumental de programes de recerca orientats en làmbit de la recercaila innovació en salut” and “Pla estrategic de recerca i innovació en salut (PERIS),” also awarded a grant to FF (SLT006/17/00246). This research was also partially funded by: Consejería de Salud de la Junta de Andalucía (PI0458/2013, PS0358/2016, PI0137/2018); Generalitat Valenciana (PROMETEO/2017/017); SEMERGEN, CIBEROBN, FEDER and ISCIII (CB06/03); EU-H2020 Grants (Eat2beNICE/h2020-sfs-2016-2, ref.728018; PRIME/h2020-SC1-BHC-2018-2020, ref: 847879).
