  • *Summary score combining information on frequency, duration and intensity among those who were active ≥1 a week (sex-specific medians defining medium and high activity). No activity and activity <1 a week were grouped as low activity.

  • Higher education defined as college or university education.

  • BMI, body mass index; BP, blood pressure; CVD, cardiovascular disease; NA, not applicable; PA, physical activity.
