title: Effect of body mass index on latency periods after history-indicated cervical cerclage.
abstract: BACKGROUND
  The impact of maternal body mass index (BMI) on cervical cerclage outcomes is not clear in the literature.
  
  
  OBJECTIVE
  We sought to investigate the impact of BMI on history-indicated cervical cerclage outcomes in our unit.
  
  
  METHODS
  We retrospectively reviewed 196 history-indicated cervical cerclage procedures. The results were analysed according to the BMI groups <25, 25-30 and ≥30 kg/m(2) .
  
  
  RESULTS
  A total of 122 cases were available for the final analysis. Thirty-two (26.1%) of the women had normal BMI (BMI < 25), 69 (56.5%) were overweight (BMI = 25-30) and 21 (17.4%) were obese (BMI ≥ 30). The mean gestational age of delivery according to BMI groups <25, 25-30 and ≥30 were 37.2 ± 3.1, 36.0 ± 5.3 and 36.0 ± 4.9 weeks (P = 0.591), respectively. The mean latency periods according to BMI groups <25, 25-30 and ≥30 were 24.3 ± 3.2, 21.1 ± 5.1 and 21.4 ± 4.9 weeks (P = 0.171), respectively. We found no correlation between the BMI and latency periods (Spearman's rho = -0.252). The multivariable logistic regression model found no variable to affect preterm birth rates.
  
  
  CONCLUSIONS
  The BMI has no impact on history-indicated cervical cerclage procedure outcomes. Normal weight, overweight and obese women had similar latency periods after history-indicated cervical cerclage. This high percentage of preterm birth risk necessitates close surveillance of these women for preterm birth.
