Dietary antioxidants, waist circumference, and pulmonary function were measured in the Fourth Scottish MONICA cross-sectional survey of 865 men and 971 women aged 25–64 years. Waist circumference was inversely related to forced expiratory volume in the first second (FEV₁) and forced vital capacity (FVC), even after adjustment for age, height, weight, working status, energy intake, and smoking variables in a multiple linear regression model (men: β = −0.017 for FEV₁ l/cm, p < 0.01 and β = −0.008 for FVC, p = 0.04; women: β = −0.009 for FEV₁, p < 0.01 and β = −0.007 for FVC, p = 0.01). After additional adjustment for waist circumference, estimated vitamin C and β-carotene intakes were positively associated with lung function in men (vitamin C: β = 0.102 for FEV₁ l/mg/day, p = 0.03; β-carotene: β = 0.073 for FVC l/μg/day, p = 0.02). Retinol and vitamin E were not significantly related to lung function for …
