Age was calculated from the date of birth to the date of answering to
the prequestionnaire. BMI was calculated as body mass (kg) divided by
height squared (m2). Body mass and height were
measured in the morning of the Phase 3 laboratory visit after overnight
fasting and participant wearing only undergarments. Level of education
was self-reported with a structured question and participants were
classified into two groups based on their answers: those with bachelor
level or higher education (tertiary) and those with education lower than
bachelor level (secondary). Work-related physical activity was assessed
also with a structured question. Based on their answers participants
were classified into three groups: mainly sedentary work, work that
includes standing and walking, and heavy work that includes also
lifting.
