The incidence was 2.2 per 1000 births and increased during the study period. Most CH cases had a spontaneous vaginal delivery. Risk factors were ventouse, born preterm, large\u2010for\u2010gestational age, and occiput posterior presentation. Two\u2010thirds were diagnosed before 7\u2009days of life. A delayed diagnosis during later infancy became more common from the year 2000. Newborn infants had an increased risk of jaundice (10%). CH was associated with hypoxic encephalopathy (2.5%), convulsions (3.5%), skull fractures (0.6%), intraventricular haemorrhage (0.2%), subdural haemorrhage (0.5%) and stroke (0.2%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A substantial number of CH cases had a delayed diagnosis.
