  1. Data are presented as mean (standard deviation) and the percentage of lifestyle represents number of “yes”/total responses. Lifestyle change scores were calculated using the sum of the scores for lifestyle questions in this table in 2012 subtracted by the summed scores of these questions in 2010
  2. BMI body mass index, HDL/LDL high/low-density lipoprotein, γ-GTP γ-glutamyl transpeptidase
