Abstract
Background: Longitudinal epidemiological data are scarce on the relation between dietary patterns and lung function in childhood.
Aims: We investigated whether three distinct dietary patterns in mid-childhood are associated with lung function in adolescence.
Methods: In the Avon Longitudinal Study of Parents and Children, ‘Junk’, ‘Traditional’, and ‘Health-conscious’ dietary patterns were identified using principal components analysis from food frequency questionnaires at 7 years of age. Post-bronchodilator FEV1, FVC, and FEF25–75 were measured at 15.5 years and were transformed to z-scores based on the Global Lung Function Initiative curves.
Results: In 3,085 participants, the Health-conscious pattern was associated with a higher FVC and FEV1, while the Junk pattern was associated with lower lung function (Table). There was no evidence of association for the Traditional pattern.
Linear regression coefficients and 95% CI for lung function measures (z scores) according to quartiles of dietary pattern scores adjusted for potential confounders
Conclusions: A healthier diet in mid-childhood is associated with higher subsequent lung function, while a diet high in processed food was associated with lower lung function.
