Table 3 Association between the intake of antioxidant nutrients, BMI, WC and glucose concentrations in Mexican adultsa

From: Higher dietary magnesium intake is associated with lower body mass index, waist circumference and serum glucose in Mexican adults

  1. aData are from the Mexican National Health and Nutrition Survey (ENSANUT) 2012. BMI: body mass index, WC: waist circumference, RAE: retinol activity equivalent
  2. bTotal sample (n = 1573). Multivariate regression analysis; adjusted by sex, age, physical activity and energy intake
  3. cOnly individuals with normal serum glucose concentrations (< 100 mg/dL) (n = 1119). Multiple regression analysis; adjusted by sex, age, energy intake, and BMI
  4. dNutrient intake per 100 kcal of energy intake = (nutrient intake / energy intake) × 100
