Adjusted differences (with 95% confidence intervals) in lung function measurements in adolescence (age, 15 yr) and early adulthood (age, 24 yr) associated with 1-cm/yr greater peak height velocity. *Adjusted for: lung function at age 8 years; age and height at visit clinics in which lung function outcomes were measured (at ages 15 and 24 yr); parity; maternal history of asthma or allergy; maternal smoking during pregnancy; birth weight; ever doctor-diagnosed asthma by age 14 years; exposure to smoke from birth to 8 years of age; and smoking status. PV = peak height velocity.
