Talaei M, Hughes DA, Mahmoud O, et al. - Researchers sought to determine if a higher consumption of preformed vitamin A or provitamin β-carotene in mid-childhood is related to higher lung function and to asthma risk in adolescence. Applying food frequency questionnaire at 7 years of age, estimation of dietary intakes of preformed vitamin A and β-carotene equivalents was done in the Avon Longitudinal Study of Parents and Children. Measurements of post- bronchodilator forced expiratory volume in 1 s, forced vital capacity (FVC), and forced expiratory flow at 25–75% of FVC were obtained at 15.5 years and transformed to z scores. Findings revealed both higher subsequent lung function as well as a lower risk of fixed airflow limitation and incident asthma in relation to a higher consumption of preformed vitamin A, but not β-carotene, in mid-childhood.
