Objective: To examine associations of dietary antioxidant intake and pulmonary function. Methods: Antioxidant data (vitamins A, C, D, E, magnesium, and omega-3 fatty acids) were abstracted from food frequency questionnaires. Pulmonary function was measured using American Thoracic Society criteria. We used analysis of variance to investigate associations. Results: Among 79 police officers (57% male), forced vital capacity was positively and significantly associated with vitamin A after adjustment for age, gender, height, race, smoking status, and pack-years of smoking, and with magnesium after adjustment for those risk factors plus total calories, all supplement use, and abdominal height. Among current/former smokers only, mean levels of all pulmonary function measures were significantly associated with vitamin E; smoking status significantly modified these relationships. Conclusions: Increased intake of vitamin A, vitamin E (among current/former smokers only), and magnesium was associated with better pulmonary function.
