Body mass index status and peripheral airway obstruction in school-age children: a population-based cohort study

Few large prospective studies have investigated the impact of body mass index (BMI) on lung function during childhood.Using data collected between 2002 and 2013, we analysed associations between BMI status and lung function (assessed by spirometry) from 8 to 16 years, as well as cross-sectional associations with small airway function (impulse oscillometry) at 16 years in the BAMSE cohort (n=2889). At 16 years, cross-sectional associations with...
