Those with low birth weights, frequently born before 32 weeks, later underwent pulmonary function testing at 16 to 33 years of age.  Compared to those born with normal weights and at term, they had a high incidence of chronic obstructive pulmonary disease.  This was particularly true for those who were diagnosed with bronchopulmonary dysplasia (BPD) during infancy. Premature babies and those with low birth weights should be followed carefully into adulthood and checked for the development of pulmonary disease.  Many will have reduced lung capacities through childhood, and their restrictive lung disease may become handicapping as they mature.
