Sex-specific associations of body weight and composition trajectories with post-bronchodilation lung function measures at age 15 years. Models are adjusted for maternal social class, maternal smoking during pregnancy, birth weight, breastfeeding, lung function measures at 8 years, pubertal status (age at menarche for girls and voice break status at age 15 yr for boys), and age and height at 15 years. Models for fat mass index and lean body mass index are also mutually adjusted. β = estimate of regression coefficient; BMI = body mass index; CI = confidence interval; FEF25–75 = forced expiratory flow, midexpiratory phase; FMI = fat mass index; LBMI = lean body mass index.
