The association between maternal height and pregnancy outcomes in twin gestations

Objective: We sought to assess the association between maternal height and the risk of preterm birth, fetal growth restriction and mode of delivery in twin gestations.

Study design: Cohort study of patients with twin pregnancies delivered from 2005 to 2014. We compared pregnancy outcomes between patients of short stature?≤159?cm to those of normal stature?≥160?cm. Patients with monoamniotic twins and major fetal anomalies were excluded. Pearson’s correlation, Chi-square and Student’s t-test were used as appropriate.

Results: Six hundred and sixty-six patients were included, 159 (23.9%) of whom had short stature (mean height 155.8?±?2.5?cm) and 507 (76.1%) of whom had normal stature (mean height 167.2?±?5.5?cm). There were no differences in outcomes between the groups in regards to preterm birth, gestational age (GA) at delivery, birth weight of either twin, preeclampsia, gestational diabetes or cesarean section rate. Results were similar when the groups were stratified by parity. As a continuous variable, maternal height did not correlate with GA at delivery (p=?0.388), cesarean delivery (p?=?0.522) nor the birth weight of the larger (p?=?0.206) or smaller (p?=?0.307) twin.

Conclusion: In twin pregnancies, maternal short stature is not associated with preterm birth, fetal growth restriction or cesarean section rate. This suggests that although anthropometric measurements have long been used to counsel patients in regards to outcomes, patients of short stature should be reassured that their height does not appear to lead to adverse twin pregnancy outcomes.

Association between maternal panic disorders and pregnancy complications and delivery outcomes

BACKGROUND: The objective of the study was to evaluate the possible association between panic disorders during pregnancy and pregnancy complications, as well as birth outcomes: gestational age and birth weight, as well as preterm birth/low birthweight in newborns. METHODOLOGY: Comparison of newborn infants (without any defects) born to mothers with or without panic disorder in the population-based large data set of the Hungarian Case-Control Surveillance System of Congenital Abnormalities. Main outcome measures were medically recorded pregnancy complications, as well as gestational age and birth weight, proportion of preterm birth and low birthweight. PRINCIPAL FINDINGS: Of 38,151 controls, 187 (0.5%) had mothers with panic disorders during pregnancy. Among pregnancy complications, anemia and polyhydramnion showed a higher prevalence in women with panic disorder. There was a higher proportion of males among newborn infants born to mothers with panic diseases compared to newborn infants of mothers without panic disorders. Pregnant women with panic disorders had a shorter (0.4 week) gestational age (adjusted t = 2.3; p = 0.02) and a larger proportion of preterm births (17.1% versus 9.1%) (adjusted POR with 95% CI = 1.9, 1.3-2.8). However, there was no significant difference in the mean birth weight and rate of low birthweight between the two study groups. CONCLUSION: Panic disorders during pregnancy were associated with anemia, a shorter gestational age and a larger proportion of preterm birth. Further studies are needed to confirm and explain or disprove the male excess among newborn infants born to mothers with panic disorders.     

Obesity and adverse pregnancy outcomes in twin pregnancies

Abstract

Objective: To compare pregnancy outcomes in twin pregnancies based on maternal pre-pregnancy body mass index (BMI).

Methods: Historical cohort study of all twin pregnancies >24 weeks managed by one maternal-fetal medicine practice from 2005 to 2012. We compared pregnancy outcomes between pre-pregnancy obese (BMI ≥30?kg/m²) and normal weight women (BMI 18.5–24.99?kg/m²). We also compared pre-pregnancy normal weight women to overweight women (BMI 25–29.99?kg/m²) and underweight women (BMI <18.5?kg/m²). Chi square, Fisher’s exact test, Student’s t-test, and one-way ANOVA were used as appropriate. A p value of <0.05 was considered significant.

Results: Five hundred fourteen patients with twin pregnancies were included. Pre-pregnancy obesity was associated with gestational hypertension (34.1% versus 17.9%, p?=?0.011), preeclampsia (27.3% versus 14.4%, p?=?0.028), and gestational diabetes (22.2% versus 4.7%, p?<?0.001). Pre-pregnancy overweight was associated with gestational diabetes (13.7% versus 4.7%, p?=?0.002). Pre-pregnancy underweight was not associated with any adverse pregnancy outcomes. Comparing outcomes across normal weight, overweight, and obese women, the rates of gestational diabetes and gestational hypertension increased significantly across the three groups.

Conclusion: In patients with twin pregnancy, pre-pregnancy obesity is associated with adverse pregnancy outcomes, including gestational diabetes, gestational hypertension, and preeclampsia.     

Maternal and perinatal complications in triplet compared with twin pregnancy

Objective: To compare maternal and perinatal complications in triplet and twin pregnancies. Study design: Case-controlled study in the setting of a University Hospital. Each pregnancy of a consecutive series of 40 triplet pregnancies of 20 weeks or more was matched for parity and maternal age with two sets of twins delivered in the same year. Primary end points of the analysis were maternal complications and perinatal outcome. Results: Of the triplets 82% and of the twins 36% were a result of assisted reproduction. Pre-term labor occurred significantly more often in triplet than in twin gestation. Triplets had a significantly lower median birth-weight (1478 vs. 2030 g) and gestational age at delivery (32 vs. 35.5 weeks). The mean neonatal hospital stay was significantly longer in triplets, mainly related to the lower birth-weight, but there was no significant difference between triplets and twins in the incidence of major neonatal complications. Conclusion: This data of the anticipated perinatal outcome in triplet and twin pregnancies may be used to counsel women with a triplet pregnancy considering selective reduction to twins. All methods of assisted reproduction should aim at prevention of multifetal gestation.     

孕早期双胎妊娠甲状腺功能减退对妊娠结局的影响

Objective?To investigate the impact of hypothyroidism of twin pregnancy in first trimester on pregnancy outcomes. Methods?A total of 1 203 cases of twin pregnant women were enrolled in this retrospective study and divided into three groups based on maternal TSH concentration in first trimester. Normal TSH group contained twin pregnant women with TSH levels between 0.01 to 3.35 mIU/L in first trimester, TSH>3.35 group contained twin pregnant women whose TSH concentrations between 3.35 to 4 mIU/L, TSH>4 group included those with TSH levels beyond 4 mIU/L. The pregnancy outcomes were analyzed between three groups. Results?Logistics analysis between maternal TSH levels and pregnancy outcomes of twin pregnancy showed TSH beyond 4 mIU/L in first trimester was corelated with the incidence of gestational diabetes mellitus (GDM), and its OR was 3.48, 95% CI was 1.27~9.55. Conclusion?The risk of GDM in twin pregnant women with hypothyroidism in first trimester may increase and TSH>4 mIU/L was one of independent risk factors of GDM.
