Values are given as mean ± SD for continuous variables and as percentages for categorical variables. ANOVA test was performed for continuous variables and Pearson’s chi-square test for categorical variables.
a Cardiovascular risk calculated by using REGICOR score: <5% (Low, LR), 5 to 9% (Moderate, MR), ≥10% (High and very high, HR) risk of suffering of a cardiovascular event in 10 years’ time.
b Beck Depression Inventory-II (BDI-II). The participant is considered to suffer of depression when getting a score of 18 or higher.
c For men, values of 0.95 or higher; for women, values of 0.85 or higher
Abbreviations: CVR, cardiovascular risk; BMI, body mass index (kg/m2); WHR, waist hip ratio.
