Relationship between education and atherosclerotic disease risk factors in patients with peripheral arterial disease

Abstract

Aim. The aim of the present study was to investigate whether different levels of education are associated with different atherosclerotic disease risk factors. Methods. The cross-sectional study, involving 388 consecutive patients with verified peripheral arterial disease, was performed in Belgrade. Formal education level was used as a proxy for socioeconomic status. Anthropometric parameters and data on cardiovascular risk factors were analyzed in participants with different levels of education. In the analysis, univariate and multivariate logistic regressions were used. Results. Multivariate analysis showed that low education was significantly positively related to alcohol consumption (Odds Ratio - OR, 4.67; 95% confidence interval - CI, 1.80-12.12), increased triglycerides (OR, 2.73; 95% CI, 1.13-6.61), and physical activity during work (OR, 43.10; 95% CI 14.37-129.28), and negatively related to former smoking (OR, 0.11; 95% CI, 0.03-0.46) and sports and leisure - time physical activity (OR, 0.13; 95% CI, 0.04-0.41 and OR, 0.25; 95% CI, 0.11-0.57). Medium education was significantly positively related to increased triglycerides (OR, 1.74; 95% CI 1.01-2.98) and increased LDL-cholesterol (OR 2.37; 95% CI, 1.35-4.18), and to physical activity during work (OR, 2.22; 95% CI, 1.34-3.67), and negatively related to age (OR, 0.95; 95% CI, 0.92-0.98) and leisure - time physical activity (OR, 0.47; 95% CI, 0.30-0.74). Conclusions. It can be concluded that if there are differences in the risk of the occurrence of peripheral arterial disease by education status, they could be only partly explained by differences in the observed atherosclerotic disease risk factors.
