title: Prospective study of infantile hemangiomas: demographic, prenatal, and perinatal characteristics.
abstract: OBJECTIVE
  To characterize demographic, prenatal, and perinatal features of patients with infantile hemangiomas and to determine the importance of these factors in predicting rates of complication and treatment.
  
  
  METHODS
  We conducted a prospective study at 7 U.S. pediatric dermatology clinics. A consecutive sample of 1058 children, aged 12 years and younger, with infantile hemangiomas was enrolled between September 2002 and October 2003. A standardized questionnaire was used to collect demographic, prenatal, perinatal, and hemangioma-specific data. National Vital Statistic System Data (NVSS) was used to compare demographic variables and relevant rates of prenatal events.
  
  
  RESULTS
  In comparison with the 2002 United States National Vital Statistics System birth data, we found that infants with hemangiomas were more likely to be female, white non-Hispanic, premature (P < .0001) and the product of a multiple gestation (10.6% versus 3.1%; P < .001). Maternal age was significantly higher (P < .0001), and placenta previa (3.1%) and pre-eclampsia (11.8%) were more common.
  
  
  CONCLUSIONS
  Infants with hemangiomas are more likely to be female, white non-Hispanic, premature, and products of multiple gestations. Prenatal associations include older maternal age, placenta previa, and pre-eclampsia. No demographic, prenatal, and perinatal factors predicted higher rates of complications or need for treatment.
