Offspring are 1.8 times more likely to develop asthma and a lifetime history of wheezing47, 48
Children diagnosed with early-onset asthma have more persistent deficits in lung function49
Other effects50–57
    Significant reductions in forced expiratory flow
    Suppression of alveolarization, functional residual capacity, and tidal flow volume
