Children's hospitalisation history was examined during two observational periods, 6\u201318 and 6\u201366\u2009months of age.

The odds ratio (95% confidence interval) for hospitalisation from 6 to 66\u2009months of age was 1.19 (1.05\u20131.34) in term children born small for gestational age and 1.47 (1.05\u20132.06) for preterm children born small for gestational age, compared with those born appropriate for gestational age.
