Detrimental effect of high social risk on the cardiovascular health status of community-dwelling older adults living in rural settings. A population-based, longitudinal prospective study.

Background: Information of the effect of social risk on the cardiovascular health (CVH) status among individuals living in rural settings is limited. We aim to assess this effect in participants of the Three Villages Study cohort.

Methods: Following a longitudinal prospective design, older adults living in rural Ecuador received baseline social risk determinations by means of social determinants of health components included in the Gijon's Social-Familial Evaluation Scale (SFES) together with clinical interviews and procedures to determine CVH status included in the Life's Simple 7 construct. Those who also received CVH assessment at the end of the study were included. Random-effects generalized least square and mixed logistic regression models were fitted to assess the longitudinal effect of social risk on CVH metrics, after adjusting for relevant covariates.

Results: The study included 443 community dwellers (mean age: 67 ± 7 years). The Gijon's SFES mean score was 9.8 ± 2.7 points. The mean number of ideal CVH metrics at baseline was 3.1 ± 1.3, which decreased to 2.6 ± 1.2 (β: -0.467; 95% C.I.: -0.588 to -0.346), after a mean of 7.31 ± 3.26 years of follow-up. The total Gijon's SFES score was higher among individuals with a worsening CVH status compared to those who did not (10.4 ± 2.6 versus 9.3 ± 2.6; p < 0.001). The ideal CVH status declined 1.23 (95% C.I.: 1.13-1.34) times per point of change in the total Gijon's SFES score.

Conclusion: Study results indicate a deleterious effect of high social risk on CVH status at follow-up in this underserved population.
