Late preterm infants had more frequent admissions than term infants in the first 5 years in both singletons (adjusted incidence rate ratio [95% confidence interval]\u2009=\u20091.46 [1.42\u20131.49]) and twins (1.21 [1.11\u20131.31]). The difference in admissions between late preterm and term infants were smaller in twins than singletons and decreased with children's ages. Twins had less frequent admissions than singletons for late preterm infants, but not for term infants. The emergency visits were more frequent in late preterm than term infants in all the periods.<\/jats:p><jats:p>\n          Conclusion\u2003Admissions and emergency visits were more frequent in late preterm than term infants through the first 5 years.
