Early life determinants of lung function change from childhood to adolescence
RATIONALE: Little is known about how perinatal and childhood factors influence lung function change between childhood and adolescence.OBJECTIVES: To investigate possible early life predictors of change in FEV1 between age 8 and 16 years. In addition, to investigate possible predictors of having persistently low lung function (FEV1 <25th percentiles both at age 8 and 16) up to adolescence.METHODS:
