  1. MVPA moderate to vigorous physical activity, CI confidence interval, FEV 1 forced expiratory volume in 1 s, FVC forced vital capacity, FEF 25-75 forced expiratory flow between 25% and 75% of FVC
  2. aLeast active MVPA quartile (1st quartile) was used as reference. All models were adjusted for sex, age, height, weight, education level, a doctor’s diagnosis of hay fever and depending on the population analyzed also by smoking status (never, ex- or current)
  3. Statistically significant associations (p < 0.05) are shown in bold
