Abstract: 【Abstract】 Objective To explore the correlation between prepregnancy body mass index (BMI) of thefull-term breech position pregnancies and neonatal admission risk. Method Used a cross-sectional studymethod, a total of 1 013 pregnant women with full-term breech position (>37 weeks) were selected, they were from the Goethe University Hospital Frankfurt, Germany from January 2004 to December 2016. Neonates were delivered into admission (n=73) and non-admission (n=940). First, the association between BMI as a continuous variable and the risk of neonatal admission was explored, then the BMI was divided into four groups: BMI<20 kg/m2 group (n=167), 20 kg/m2≤BMI<24 kg/m2 group (n=534), 24 kg/m2≤BMI<28 kg/m2 group (n=220) and BMI≥28 kg/m2 group (n=92). The association between BMIand neonatal admission risk was analyzed. Statistical methods performed by χ2 test, t test, rank sum test andLogistic regression analysis. Result The mean BMI of 1 013 full-term breech position pregnancies was(23.10±3.92) kg/m2. And the admission rate of all neonates was 7.2% (73/1 013). Logistic regression analysisshowed that neonatal admission risk increased with increasing maternal prepregnancy BMI. The risk increasedby 6.3% for each 1 kg/m2 increase in BMI (95%CI: 1.010-1.119, P=0.019). After adjusting for gestation, thenumber of births, birth weight, mode of delivery, degree of vaginal tearing, perineal incision, assisted deliveryof the fetal shoulder, and assisted delivery of the fetal head, the risk of neonatal admission increased by 5.7%(95%CI: 1.000-1.118, P=0.050). When taking 20 kg/m2≤BMI<24 kg/m2 as the reference group, the risk ofneonatal admission to hospital in the BMI<20 kg/m2, 24 kg/m2≤BMI<28 kg/m2, and BMI≥28 kg/m2 threegroup increased by 3.7%, 7.6% and 142.0% respectively. After all adjustments, the risk of neonatal admissionincreased by 28.2% (95%CI: 0.616-2.670, P=0.507), 7.9% (95%CI: 0.563-2.066, P=0.819), 125.8% (95%CI:1.097-4.646, P=0.027) compared with the reference group, respectively. Conclusion The risk of neonataladmission increases with the increase of prepregnancy BMI of full-term breech position pregnancies. The risk is more significant when BMI≥28 kg/m2.
