Beta-coefficients (ß), 95% confidence intervals (CIs), p-values, and adjusted R-Squared (R²) were estimated using linear regression
Model 1: adjusted for age (years, continuous), gender (male, female), and energy intake (kcal/d, continuous)
Model 2: Model 1 + marital status (‘never married, married, formerly married), education (‘Never/Elementary and Lower/Intermediate, Higher/University), employment status (no, yes)
Model 3: Model 2 + smoking status (never, ever), alcohol consumption (no, yes), and physical activity (MET-minutes/week, continuous)
