Dietary patterns, lung function and asthma in childhood: a longitudinal study.

ABSTRACT:

Background

Longitudinal epidemiological data are scarce examining the relationship between dietary patterns and respiratory outcomes in childhood. We investigated whether three distinct dietary patterns in mid-childhood were associated with lung function and incident asthma in adolescence.

Methods

In the Avon Longitudinal Study of Parents and Children, 'processed', 'traditional', and 'health-conscious' dietary patterns were identified using principal components analysis from food frequency questionnaires at 7 years of age. Post-bronchodilator forced expiratory volume in 1 s (FEV₁), forced vital capacity (FVC), and forced expiratory flow at 25-75% of FVC (FEF_25-75) were measured at 15.5 years and were transformed to z-scores based on the Global Lung Func
