  • *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.

  • †Adjusted for age (continuous); education (≤9 years, 10–12 years, >12 years; unknown); alcohol frequency in the past 2 weeks (no, 1–4, ≥5, abstainer; unknown); smoking (never, former, current, unknown); BP medication use (yes, no, unknown); prevalent CVD (yes, no, unknown).

  • ‡Mutually adjusted for BMI and PA summary score in addition to covariates†.

  • BMI, body mass index; BP, blood pressure; C, cases; CVD, cardiovascular disease; NA, not applicable; PA, physical activity; Pers., persons; RR, risk ratio.
