Asthma rates 'rose to 14% in babies born prematurely'

Scientists say that with increasing numbers of babies surviving premature birth, childhood asthma is set to become a significant health problem.

The research showed that average asthma rates rose to 14% in babies born prematurely, defined as at least three weeks early.
