title: Pregnancy in women with type 1 diabetes: have the goals of St. Vincent declaration been met concerning foetal and neonatal complications?
abstract: OBJECTIVE
  In 1989 the St. Vincent declaration set a five-year target for approximating outcomes of pregnancies in women with diabetes to those of the background population. We investigated and quantified the risk of adverse pregnancy outcomes in pregnant women with type 1 diabetes (T1DM) to evaluate if the goals of the 1989 St. Vincent Declaration have been obtained concerning foetal and neonatal complications.
  
  
  METHODS
  Twelve population-based studies published within the last 10 years with in total 14,099 women with T1DM and 4,035,373 women from the background population were identified. The prevalence of four foetal and neonatal complications was compared.
  
  
  RESULTS
  In women with T1DM versus the background population, congenital malformations occurred in 5.0% (2.2-9.0) (weighted mean and range) versus 2.1% (1.5-2.9), relative risk (RR) = 2.4, perinatal mortality in 2.7% (2.0-6.6) versus 0.72% (0.48-0.9), RR = 3.7, preterm delivery in 25.2% (13.0-41.7) versus 6.0% (4.7-7.1), RR = 4.2 and delivery of large for gestational infants in 54.2% (45.1-62.5) versus 10.0%, RR = 4.5. Early pregnancy HbA1c was positively associated with adverse pregnancy outcomes.
  
  
  CONCLUSIONS
  The risk of adverse pregnancy outcomes was two to five times increased in women with T1DM compared with the general population. The goals of the St. Vincent declaration have not been achieved.
