title: [A meta-analysis of the maternal Body Mass Index and the risk of stillbirth].
abstract: OBJECTIVE
  To clarify the association of stillbirth with the maternal Body Mass Index (BMI).
  
  
  METHODS
  We performed a comprehensive search from PubMed and EMbase to identify studies pertaining to the association between stillbirth and BMI. The statistical software, STATA (version 12.0) was applied to investigate heterogeneity among individual studies and summarize the studies.
  
  
  RESULTS
  Our analysis included a total of 17 articles that examined the effect of overweight on the risk of stillbirth. The association between overweight and the risk of stillbirth was statistically significant (OR 1.30, 95% CI: 1.26-1.35); 25 articles that examined the effect of obesity on the risk of stillbirth. The association between obesity and the risk of stillbirth was statistically significant (OR 1.71, 95% CI 1.66-1.76).
  
  
  CONCLUSIONS
  Overweight and obesity can increase the risk of stillbirth.
