  1. Abbreviations: DHD15-index, Dutch Healthy Diet Index 15; NRD9.3, Nutrient Rich Diet score 9.3;GHGE, greenhouse gas emissions; FE, fossil energy use; LU, land use; pReCiPe, a weighted summary score for GHGE, FE, and LU
  2. aValues are expressed as mean (standard deviations), numbers and percentages. Comparisons between men and women were tested by independent samples t-test for continuous variables and chi-square test for categorical variables. All characteristics above were statistically significant using P-value below 0.05. bData were available for 1168 subjects, i.e. 605 men and 563 women. cData were available for 1167 subjects, i.e. 605 men and 562 women. dData were available for 1112 subjects, i.e. 578 men and 534 women. e Dietary estimates were crude values based on two 24-h recalls
