Abstract
Childhood BMI has been reported to be positively associated with adult lung function. The aim of this study was
to investigate the effect of childhood BMI on young adult lung function independently of the effects of lean body
mass (LBM). Clinical and questionnaire data were collected from 654 young Australian adults (aged 2736 years),
first studied when age 9, 12, or 15 years. Adult lung function was measured by forced vital capacity (FVC), forced
expiratory volume in 1 s (FEV1), FEV1/FVC ratio, and the forced expiratory flow in the middle 50% of FVC (FEF2575).
BMI and LBM were derived from anthropometric measures at baseline (1985) and at follow-up (20042006).
Multivariable models were used to investigate the effect of age and sex standardized BMI in childhood on adult
lung function, before and after adjustment for LBM. Adult adiposity had a strong deleterious effect on lung function,
irrespective of childhood BMI, and adjustment for childhood LBM eliminated any apparent beneficial effect of
childhood BMI on adult FEV1 or FVC. This suggests that the beneficial effect of increased BMI in childhood on adult
FEV1 and FVC observed in previous longitudinal studies is likely to be attributable to greater childhood LBM not
adiposity. Obese children who become obese adults can expect to have poorer lung function than those who maintain
healthy weight but large deficits in lung function are also likely for healthy weight children who become obese adults.
This highlights the importance of lifetime healthy weight maintenance.
