Cesarean section rates in Lithuania using Robson Ten Group Classification System.

BACKGROUND AND OBJECTIVE The aim of this study was to analyze cesarean section (CS) rates using Robson Ten Group Classification System (TGCS) and to identify the main contributors to the overall CS rate in Lithuania. MATERIALS AND METHODS A prospective cross-sectional study was carried out. All women who delivered between January 1 and December 31, 2012, in Lithuania were classified using the TGCS. The CS rates overall and in each Robson group were calculated, as was the contribution of each group to the overall CS rate. RESULTS The CS rate was 26.4% (6697 among 25,373 deliveries) in 2012. Nulliparous women with single cephalic full-term pregnancy in spontaneous labor (Group 1) or who underwent induction of labor or prelabor CS (Group 2) and multiparous women with a previous CS (Group 5) were the greatest contributors (67.7%) to the overall CS rate. In addition, significant variation of CS rates between different institutions was observed, especially in women with single cephalic full-term pregnancy without previous CS (Groups 1-4), showing big differences in obstetric care across country. CONCLUSIONS Women in Groups 1, 2 and 5 were the largest contributions to the overall CS rate in Lithuania. It seems that efforts to reduce the overall CS rate should be directed on increasing vaginal birth after CS and reducing CS rates in nulliparous women with single cephalic full-term pregnancy (Groups 1 and 2).

Maternal obesity and obstetric outcomes in a tertiary referral center

BACKGROUND AND AIM Obese women are at an increased risk of various adverse pregnancy outcomes. The aim of our study was to evaluate the impact of obesity on maternal and neonatal outcomes in a tertiary referral center and to compare obstetric outcomes by the level of maternal obesity. MATERIALS AND METHODS A cohort study included 3247 women with singleton gestations who gave birth at the Department of Obstetrics and Gynecology, Lithuanian University of Health Sciences, in 2010. Pregnancy complications and neonatal outcomes were identified using the hospital Birth Registry database in normal weight (body mass index [BMI] 18.5-24.9kg/m2, n=3107) and prepregnancy obese (BMI ≥30kg/m2, n=140) women. Pregnancy outcomes were compared according to the level of obesity (BMI 30-34.9kg/m2, n=94 and BMI ≥35kg/m2, n=46). RESULTS Obese women were significantly more likely to have gestational hypertension (OR=8.59; 95% CI, 5.23-14.14; P<0.0001), preeclampsia (OR=2.06; 95% CI, 1.14-3.73; P<0.0001), gestational diabetes (OR=5.56; 95% CI, 3.66-8.49; P<0.0001), dystocia (OR=2.14; 95% CI, 1.36-3.38; P<0.0001), induced labor (OR=2.64; 95% CI, 1.83-3.80; P<0.0001), failed induction of labor (OR=18.06; 95% CI, 8.85-36.84; P<0.0001), cesarean delivery (OR=1.76; 95% CI, 1.25-2.49; P=0.001), large-for-gestational-age newborns (OR=3.68; 95% CI, 2.51-5.39; P<0.0001). Significantly increased risk of gestational diabetes, preeclampsia, dystocia and newborns with Apgar score ≤7 after 5min was only observed in women with BMI ≥35kg/m2. CONCLUSIONS Maternal obesity is significantly associated with an increased risk of gestational hypertension, preeclampsia, gestational diabetes, dystocia, labor induction, failed induction of labor, large-for-gestational-age newborns and cesarean delivery.
