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

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

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