  • Model 1: adjusted for age and sex.

  • Model 2: adjusted for model 1 plus BMI, WHR, hypertension, diabetes, dyslipidaemia, smoking, alcohol consumption and physical activity.

  • *P < 0.001, **P < 0.05.

  • BMI, body mass index; CVD, cardiovascular disease; PRs, prevalence ratios; WHR, waist to hip ratio.
