Insights
The co-occurrence of depression and frailty in older adults significantly increases cardiovascular disease (CVD) risk. This combined geriatric syndrome phenotype presents a heightened CVD burden, even after accounting for traditional risk factors.
Area of Science:
- Geriatric Medicine
- Cardiovascular Health
- Mental Health
Background:
- Depression and frailty are common conditions in older adults.
- Their combined presence may indicate a higher risk for cardiovascular disease (CVD).
- The association between co-occurring depression, frailty, and CVD in Latin America remains understudied.
Purpose of the Study:
- To investigate the relationship between the overlap of depression and frailty and the prevalence of CVD in an older adult population.
- To characterize this association within the Latin American context.
Main Methods:
- Cross-sectional analysis of the 2015 SABE Colombia study data.
- Inclusion of adults aged 60 years and older with data on depression, frailty, and CVD (myocardial infarction or stroke).
- Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated using log-binomial regression models.
Main Results:
- 18,973 participants were analyzed, with prevalences of 57.3% for depression, 3.5% for frailty, and 15.4% for CVD.
- The overlap of depression and frailty showed the strongest association with CVD (PR 4.86; 95% CI 3.37-7.01) in multivariate analyses.
- This association remained significant after adjusting for traditional cardiovascular risk factors (PR 2.05; 95% CI 1.05-3.97).
Conclusions:
- The co-occurrence of depression and frailty is independently associated with a higher prevalence of CVD in older adults.
- This combined geriatric syndrome phenotype signifies an increased cardiovascular burden.
- Clinical attention to both depression and frailty is crucial for managing CVD risk in the elderly.
Background:
Depression and frailty are prevalent geriatric syndromes. Their co-occurrence may define a phenotype of heightened cardiovascular disease (CVD). In Latin America the joint association of these syndromes with CVD has not been previously characterised.
Objective:
To evaluate the association between the overlap of depression and frailty and the prevalence of CVD in older adults.
Methods:
A cross-sectional analysis was conducted using data from the 2015 SABE Colombia study. Adults aged ≥60 years with complete information on depression, frailty, and history of acute myocardial infarction or stroke defined as CVD were included. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated using bivariate and multivariate log-binomial regression models.
Results:
18,973 participants were analysed (mean age 69.3 ± 7.1 years; 56% women). The prevalence of depression, frailty, and CVD was 57.3%, 3.5%, and 15.4%, respectively. In bivariate analyses, depression (PR 1.83, 95% CI 1.51-2.23), prefrailty (PR 1.61, 95% CI 1.50-1.73), and frailty (PR 2.91, 95% CI 2.57-3.28) were associated with CVD. In multivariate model, the overlap of depression and frailty demonstrated the strongest association with CVD (PR 4.86; 95% CI 3.37-7.01), exceeding that of depression with prefrailty and each condition individually. This association persisted after adjustment for traditional cardiovascular risk factors (PR 2.05, 95% CI 1.05-3.97).
Conclusion:
In older adults, the overlap of depression and frailty remained associated with a higher prevalence of CVD after adjustment for traditional cardiovascular risk factors. Although the association was attenuated after adjustment, the coexistence of both conditions remained associated with increased cardiovascular burden.
