Oxidative balance score components.

OBS components	Assignment scheme
Nondietary pro-oxidants
Obesity	0 = BMI ≥ 30 kg/m^2 AND WC ≥ 1.02 m in males or ≥0.88 m in females; 1 = BMI ≥ 30 kg/m^2 OR WC ≥ 1.02 m in males or ≥0.88 m in females; 2 = BMI < 30 kg/m^2 AND WC < 1.02 m in males or <0.88 m in females
Smoking	0 = current, 1 = former, and 2 = never
Nondietary antioxidants
Physical activity (MET-min/d)	0 = low (1^st tertile), 1 = medium (2^nd tertile), and 2 = high (3^rd tertile)
