¹Time spent by using a computer, watching television or reading;

²Climbing stairs, short walking and house-keeping chores, etc. The higher the score the lower is the activity (1-every day, 5-never). BMI: Body mass index; LDL: Low density lipoprotein; HDL: High density lipoprotein; ALT: Alanine aminotransferase; AST: Aspartate transaminase; GGT: Glutamyl transpeptidase.
