INTRODUCTION: High maternal body mass index (BMI) is associated with complications during pregnancy and delivery such as gestational diabetes, hypertensive disorders, perineal injuries and macrosomia. The aim of this study was to assess the association between maternal BMI and delivery method in non-breech, singleton deliveries, after 36 weeks of gestation, in women with no more than one previous cesarean section, in Oslo University Hospital, Ulleval. MATERIAL AND METHODS: This retrospective register study used data from the hospital obstetrical database in 2011-2012, forming a cohort of 8821 women. Women were categorized into five different BMI classes and stratified into subgroups according to parity and previous cesarean delivery. Mode of delivery was categorized to spontaneous delivery, instrumental vaginal delivery, planned cesarean section and emergency cesarean section. RESULTS: Incidence of emergency cesarean delivery increased with increasing maternal BMI. Among primiparous women with overweight or obesity, the caesarean delivery rate was doubled (23.2 and 29.1%, respectively), compared with women with underweight or normal weight (12.5 and 13.7%). Also among parous women, maternal BMI ≥30 doubled the risk for cesarean delivery. The strongest risk factor for planned or emergency cesarean delivery was previous cesarean section [adjusted odds ratio 16.41 (confidence interval 12.19-22.08) and 8.72 (6.33-12.02), respectively]. Maternal BMI ≥30 increased the risk of planned cesarean delivery by 77%, and doubled the risk of emergency cesarean delivery. CONCLUSIONS: Prepregnancy BMI ≥30 was an independent risk factor for delivery by emergency cesarean section for both primiparous and parous women.

Objective To develop a complete, population-based system for ultrasound-based fetal size monitoring and birth-weight prediction for use in the second and third trimesters of pregnancy. Methods Using 31 516 ultrasound examinations from a population-based Norwegian clinical database, we constructed fetal size charts for biparietal diameter, femur length and abdominal circumference from 24 to 42 weeks' gestation. A reference curve of median birth weight for gestational age was estimated using 45 03...

Abstract Objective To examine factors associated with successful vaginal birth after cesarean (VBAC) and to validate a previously established prediction model. Methods In a retrospective study, data were obtained for women with one prior low-transverse cesarean procedure who underwent a trial of labor with a cephalic singleton pregnancy at term at one UK hospital between January 2000 and August 2013. Univariate analysis and logistic regression analysis were used to identify maternal demographic ...

OBJECTIVE: To investigate the relationship between prepregnancy obesity and maternal outcomes. METHODS: A 15-year, population-based cohort study using the Nova Scotia Atlee Perinatal Database compared maternal outcomes in obese and nonobese women. Prepregnancy weight of 55-75 kg was considered nonobese, and weight greater than 90 kg was considered obese. Obese women were categorized into moderate obesity (90-120 kg) and severe obesity (> 120 kg) groups. Univariate and multivariable logistic regr...

Objective This study was undertaken to determine whether vaginal birth after cesarean (VBAC) or elective repeat cesarean delivery is safer overall for a woman with a prior vaginal delivery. Study design This retrospective cohort study of pregnant women from 1996 to 2000 who had a prior cesarean delivery, was conducted in 17 centers. Trained nurses extracted historical and maternal outcome data on subjects by using standardized tools. This planned secondary analysis examined the subcohort that ha...

Abstract In Norwegian adult men, body mass index (BMI) increased from around 25kg/m 2 in the late 1960s to around 26.5kg/m 2 in the late 1990s, and the prevalence of obesity increased from about 5% to 15% in the same period. In women the prevalence of obesity actually decreased from around 13% in the late 1960s to 7% in the late 1980s. However, during the last years the prevalence has also increased reaching about 13% in the late 1990s. It is important to note that both mean and median BMI has i...

The rising caesarean section (CS) rate is a complex issue, particularly in an increasingly heterogenous nulliparous population. The study aim was to stratify the CS rate in nulliparous women by age and BMI to determine if any difference existed. This was a retrospective review of CS procedures of nulliparous women in two centres in Ireland (2014 through 2017). Data were obtained for 17,177 women from the hospital databases and CS procedures determined for each age and BMI category. Significant d...

BACKGROUND Maternal body mass index (BMI) below or above the reference interval (18.5-24.9 kg/m2) is associated with adverse pregnancy outcomes. Whether BMI exerts an effect within the reference interval is unclear. Therefore, we assessed the association between adverse pregnancy outcomes and BMI, in particular within the reference interval, in a general unselected pregnant population. METHODS Data was extracted from a prospective population-based multicentre cohort (Risk Estimation for PrEgnanc...
