In 1983, 1338 liveborn infants with a gestational age of less than 32 weeks and/or a birthweight of less than 1500 g, were enrolled in a national follow-up study in The Netherlands. At the age of 5 years, 966 children were alive. Of these, 927 (96%) were assessed on a home visit 2-6 weeks after their fifth birthday by three specially trained paediatricians. An assessment of ENT morbidity was made and compared with ENT morbidity in full-term children of the same age group. Markedly preterm birth or very low birthweight does not seem to be a risk factor for developing middle ear disease in childhood, however, the rate of ENT problems seems to be higher than in the general population of Dutch pre-school children.
