  1. Abbreviation: BMI body mass index, CI confidence intervals, NEI net equivalised income
  2. aCategories of NEI are based on the income distribution in the city of Leipzig in 2013. They represent < 60% (< 759 €), 60 – < 80% (759 – < 1012 €), 80 – < 100% (1012 – < 1265 €), 100 – < 150% (1265 – < 1897.50 €), 150 – < 200% (1897.50 – < 2530 €), and ≥ 200% (≥ 2530 €) of the NEI median
  3. bFigures represent medians (interquartile ranges)
  4. cFigures represent estimated marginal means (95% CI). Model 1: adjustment for age (metric variable), model 2: adjustment for age and education (metric variable), model 3: adjustment for age, education, occupation (metric variable), and employment status (employed, unemployed, inactive – only for participants < 65 years). See Table S1 for the definition of confounding variables
