Lung age

1. Bronchodilator improves lung age in humans (34.03% improved to normal group, P<0.001).

   “After bronchodilator, LA significantly improved and 34.03% of those in normally high LA improved to normal group (all P<0.001)”

1. Waist-to-height ratio increases lung age in humans (β = 6.393, p < 0.001).

   “The WHtR ≥ 0.55 was significantly related to an increase in lung age (β = 6.393, p < 0.001).”

1. Lung age is associated with FEV1 in humans (r=-0.80 to -0.46, all P<0.001).

   “DeltaLA was correlated with FEV1, forced expiratory flow at 50% of FVC (FEF50%), forced expiratory flow at 75% of FVC (FEF75%), and FVC (r=-0.80 to -0.46, all P<0.001).”

1. Metabolic syndrome is associated with lung age in humans (59.4 ± 18.7 years vs 49 ± 18.4 years).

   “Workers suffering from MetS showed an accelerated lung aging (59.4 ± 18.7 years vs 49 ± 18.4 years).”
