Abstract
Background: Over the last few years, cesarean delivery rates have increased in several well-industrialized countries, such as the United States and England. According to the data of the National Health Insurance in Taiwan, the rates of cesarean delivery maintained high from 33.68% in 1995 to 32.67% in 2003. Obesity and excess gestational weight gain have been associated with multiple adverse perinatal outcomes, including increased rates of cesarean delivery.
Objective: The purpose of this study was to investigate effect of BMI change during pregnancy on risk for cesarean delivery.
Study design: A retrospective cohort study was conducted from December 1, 2003 to April 30, 2005. All women delivered in a regional hospital in Taipei County were eligible. Preterm deliveries and planned cesarean deliveries were excluded. Univariate and multivariate logistic regressions were introduced.
Results: During study period, 1960 women delivered and total cesarean delivery rate was 33.5%. After exclusion, 1392 women were retained in this study. Primary unplanned cesarean delivery rate was 11.35%. Increased risks of cesarean delivery was associated with higher pre-pregnancy BMI (OR:1.10, 95% CIs: 1.04~1.15) and excessive gestational weight gain (OR:1.05, 95% CIs: 1.01~1.09). Among women aged less than 35 year, risks of cesarean delivery was associated with BMI increase during pregnancy (OR:1.13, 95% CIs: 1.03~1.25).
Conclusion: BMI change during pregnancy is an important risk factor for cesarean delivery, especially among women aged less than 35 year.
