From: Dietary habits and metabolic risk factors for non-communicable diseases in a university undergraduate population

Measure of obesity Male (N = 228) Female (N = 275) Total χ2* p

  1. Body mass index: overweight, > 25–29.99 kg/m2; obesity, > 30 kg/m2
  2. Waist circumference (WC: overweight: > 94 cm(M); > 80 cm(F), obesity: > 102 cm(M); > 88 cm(F)
  3. Waist-to-hip ratio (WHR): obesity ≥ 0.90 cm(M); ≥ 0.85 cm(F)
  4. *Chi-square test is for a difference in frequency of obesity between males and females as measured by each method
