abstract
The relationship between lung function decline and dietary antioxidants over 10 years in adults from three European countries was investigated. In 2002, adults from three participating countries of the European Community Respiratory Health Survey (ECRHS) answered a questionnaire and underwent spirometry (forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC)), which were repeated 10 years later. Dietary intake was estimated at baseline with food frequency questionnaires (FFQ). Associations between annual lung function decline (mL) and diet (tertiles) were examined with multivariable analyses. Simes' procedure was applied to control for multiple testing. A total of 680 individuals (baseline mean age 43.8 +/- 6.6 years) were included. A per-tertile increase in apple and banana intake was associated with a 3.59 mL.year-1 (95% CI 0.40, 7.68) and 3.69 mL.year-1 (95% CI 0.25, 7.14) slower decline in FEV1 and FVC, respectively. Tomato intake was also associated with a slower decline in FVC (4.5 mL.year-1; 95% CI 1.28, 8.02). Only the association with tomato intake remained statistically significant after the Simes' procedure was performed. Subgroup analyses showed that apple, banana and tomato intake were all associated with a slower decline in FVC in ex-smokers. Intake of fruits and tomatoes might delay lung function decline in adults, particularly in ex-smokers.
