¹Indicates on the number of people with available measure;

²Time spent by using a computer, watching television or reading;

³Climbing 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; TG: Triglycerides.
