The incidence of hypothermia was 29.5 and 13.9% between 1994\u20132005 and 2006\u20132012, respectively. In comparison with normothermic infants, hypothermic infants had lower gestational age at birth (26 vs. 27\u2009weeks) and lower birthweight (800 vs. 976\u2009g). In\u2010hospital mortality was higher in hypothermic infants (28.5 vs. 12.9%; odds ratio (OR) 2.69, 95% confidence interval (CI) 2.37\u20133.06). Severe intraventricular haemorrhage (12.1 vs. 8.5%, OR 1.48, 95% CI 1.25\u20131.75), necrotising enterocolitis (NEC) (11.0 vs. 7.5%; OR 1.54, 95% CI 1.29\u20131.83) and severe retinopathy of prematurity (16.5 vs. 8.9%; OR 2.02, 95% CI 1.70\u20132.39) were significantly higher in hypothermic infants.
