Objective: To investigate the effects of maternal body mass index (BMI) and total weight gain during the pregnancy (WGDP) on all stages of labor. Material and Methods: This is a prospective case-control study carried out at a tertiary referral hospital during 1-year period of time. We divided study population into 4 groups according to BMI and classified women according to WGDP; inadequate, optimum, excessive. Then we assessed the maternal characteristics, cesarean rate, all variables of labor stages, delivery complications, operative delivery rates, and interventions such as; induction rate and episiotomy. Results: A total of 523 women were included in the study [n=55 (10.5%) cesarean section and n=468 (89.5%) vaginal delivery]. There were 435 pregnant Turkish women and 88 Syrian Refugees in the study population. Younger maternal age and need for episiotomy was more common in low-weight group than others. All stages of labor except transition stages (duration between 7 and 10 cm of cervical dilatation) was longer in obese group (222.9±35.6 min, 195.8±29.6 min, 200.6±30.4 min, 255.8±38.2 min in group 1,2,3 and 4, respectively) (p<0.05). We found no statistically significant effect of weight gain on the duration of labor. Conclusion: Either low and high pre-gestational BMI are found to lead to increased risk of adverse labor results in compatible with literature. Therefore, professionals should support weight loss or gain to achieve optimal BMI in women planning pregnancy. [ABSTRACT FROM AUTHOR]

Objective: We aimed to determine if any of the second trimester serum marker levels had a significant association with birth weight in uncomplicated pregnancies. Material and Method: Five hundred and forty pregnant women whose second trimester (16-18 weeks) aneuploidy screening and delivery was performed at SBU Zekai Tahir Burak Health Application and Research Center Obstetrics and Gynecology Clinic, are included in this retrospective study. All women had their last menstrual period confirmed by their first trimester ultrasound. Levels of maternal serum alpha-fetoprotein (AFP), β-human chorionic gonadotropin (hCG), and unconjugated estriol (uE3) were calculated as coefficients of the median (MoM). Associations between the second trimester markers levels and infant birth weights were assessed using correlation analysis. The effects of various contributing factors on birth weight were investigated with linear regression analysis. Results: There were significant negative correlations between maternal age at screening (r =-0.48; p =0.03), maternal serum AFP level (r =-0.45; p =0.03) and birth weight of the newborn. Besides, there were positive correlations between amount of weight gain during pregnancy (r =0.44; p =0.04), maternal serum uE3 level (r =0.47; p =0.03) and birth weight of newborn. However, maternal weight and BMI at screening and maternal serum β hCG level did not have a significant correlation with birth weight of newborn. However, maternal serum uE3 level was the only factor that affected the birth weight on linear regression model. Conclusion: Second trimester maternal serum uE3 level might be useful in predicting birth weight among uncomplicated pregnant women. [ABSTRACT FROM AUTHOR]
