title: [Risk factors associated with spontaneous preterm deliveries before 30 weeks in Martinique F.W.I.: a case-control study].
abstract: OBJECTIVE
  Early premature delivery is more prevalent in overseas territories than in continental France. Many differences are observed between pregnant women in France and in Martinique which may explain the higher preterm birth rate in the latter territory. The study compares prevalence of possible risk factors in preterm and term deliveries in Martinique.
  
  
  METHODS
  A retrospective study was conducted during two years (2010-2011). All deliveries before 30 weeks were included and several characteristics were compared with a group of term deliveries during the same period. All premature deliveries before 30 weeks were collected but only spontaneous ones were analysed.
  
  
  RESULTS
  Fifty deliveries before 30 weeks were recorded, among which 38 were spontaneous. Only a significantly higher prevalence of previous preterm delivery (OR=4.1 [1.3-13]) and twin pregnancies (OR=26.6 [3.19-219.6]) was found in the study group. Gram negative bacterial species were also more prevalent in vaginal sampling of preterm deliveries (OR=23.3 [2.7-204.6]).
  
  
  CONCLUSIONS
  Factors linked to prematurity before 30 weeks in Martinique are classical. Several features are different between pregnant women in France and in Martinique but do not appear as risk factors for prematurity in the latter territory.
