Association between gestational weight gain in women with gestational diabetes mellitus and adverse pregnancy outcomes: a retrospective cohort study

Abstract Background To examine association between gestational weight gain (GWG) in women with gestational diabetes mellitus (GDM) and adverse pregnancy outcomes (APOs). Methods This retrospective cohort study enrolled women with GDM who delivered at 2010–2020 in Changzhou, Jiangsu. Total GWG, rates of GWG in second trimester and third trimesters were stratified into three categories according to IOM guidelines: within, below, and above IOM guidelines. Univariable and multivariable logistic regression analyses were used. Results Overall, 1606 women with GDM fulfilled inclusion criteria. Compared with within IOM guidelines and after adjusting for confounders, total GWG above IOM guidelines in pregnancy was associated with an increased odds of caesarean delivery [adjusted odds ratio (aOR) = 1.34, 95% confidence interval (CI): 1.04–1.72], hypertensive disorders of pregnancy (HDP) (aOR = 2.00, 1.28–3.12), preeclampsia (aOR = 2.06, 1.01–3.12), macrosomia (aOR = 1.55, 1.13–2.13) and large for gestational age (LGA) (aOR = 2.82, 1.94–3.23), and a decreased odds of premature rupture of membrane (PROM) (aOR = 0.46, 0.36–0.60) and preterm birth (aOR = 0.35, 0.26–0.44); total GWG below IOM guidelines in pregnancy was associated with an increased risk of preterm birth (aOR = 1.96, 1.44–2.66), small for gestational age (SGA) (aOR = 1.32, 1.11–1.50) and a decreased odds of macrosomia (aOR = 0.35, 0.23–0.53) and LGA (aOR = 0.54, 0.42–0.72). Further, in both second and third trimesters of pregnancy, rates of GWG above IOM guidelines was found to be associated with a high odds of HDP (aOR = 2.55, 1.86–3.38; aOR = 1.93, 1.08–2.98), preeclampsia (aOR = 2.28, 1.21–3.81; aOR = 2.17, 1.35–4.37), macrosomia (aOR = 1.20, 1.02–1.82; aOR = 2.02, 1.51–2.64) and LGA (aOR = 1.42, 1.24–1.97; aOR = 1.79, 1.51–2.54). Rates of GWG above IOM guidelines in third trimester of pregnancy also increased odds of caesarean delivery (aOR = 1.48, 1.16–2.34) when compared with within IOM guidelines. While rates of GWG below IOM guidelines in both second and third trimesters of pregnancy was associated with a decreased odds of macrosomia (aOR = 0.66, 95% CI: 0.52–0.78; aOR = 0.52, 0.39–0.63) and LGA(aOR = 0.71, 0.51–0.82; aOR = 0.67, 0.55–0.79). In addition, rate of GWG below IOM guidelines in third trimester of pregnancy was associated with an increased odds of preterm birth (aOR = 1.52, 1.12–2.05) and SGA (aOR = 1.21, 1.10–1.69). Conclusion GWG, outside IOM guidelines has increased risks of APOs among women with GDM, implying that careful surveillance for GWG during different stages of pregnancy is warranted.

Abstract Purpose: To examine the association between gestational weight gain (GWG) in women with gestational diabetes mellitus (GDM) and adverse pregnancy outcomes (APOs).Methods: This retrospective cohort study enrolled women with GDM and singleton live birth pregnancies who delivered between January 2010 and December 2020. Univariable and multivariable logistic regression analyses were used to determine the association between GWG outside the Institute of Medicine (IOM) guidelines and APOs.Results: Overall, 1606 women with GDM fulfilled the inclusion criteria. After adjusting for confounders, total GWG above IOM guidelines in pregnancy was associated with an increased risk of caesarean delivery [adjusted odds ratio (aOR)=1.34, 95% confidence interval (CI): 1.04-1.72], hypertensive disorders of pregnancy (HDP) (aOR=2.00, 95% CI: 1.28-3.12), preeclampsia (aOR=2.06, 95% CI: 1.01-3.12), macrosomia (aOR=1.55, 95% CI: 1.13-2.13) and LGA (aOR=1.83, 95% CI: 1.43-2.10), and a decreased risk of premature rupture of membrane (PROM) (aOR=0.46, 95% CI: 0.36-0.60) and preterm birth (aOR=0.35, 95% CI: 0.26-0.44); total GWG below IOM guidelines in pregnancy was associated with an increased relative risk of preterm birth (aOR=1.96, 95% CI: 1.44-2.66) and SGA (aOR=1.32, 95% CI: 1.11-1.50) and a decreased relative risk of macrosomia (aOR=0.35, 95% CI: 0.23-0.53). Further, in both second and third trimesters of pregnancy, GWG above IOM guidelines was found to be associated with a high risk of HDP (aOR=2.55, 95% CI: 1.86-3.38; aOR=1.93, 95% CI: 1.08-2.98), preeclampsia (aOR=2.28, 95% CI: 1.21-3.81; aOR=2.17, 95% CI: 1.35-4.37), macrosomia (aOR=1.20, 95% CI: 1.02-1.82; aOR=2.02, 95% CI: 1.51-2.64) and LGA (aOR=1.65, 95% CI: 1.36-2.04; aOR=1.88, 95% CI: 1.62-2.18). GWG above IOM guidelines in the third trimester of pregnancy also increased the risk of caesarean delivery (aOR=1.48, 95% CI: 1.16-2.34). While GWG below IOM guidelines in both second and third trimesters of pregnancy was associated with a decreased relative risk of macrosomia (aOR=0.66, 95% CI: 0.52-0.78; aOR=0.52, 95% CI: 0.39-0.63). In addition, GWG below IOM guidelines in the third trimester of pregnancy was associated with an increased relative risk of preterm birth (aOR=1.52, 95% CI: 1.12-2.05) and SGA (aOR=1.21, 95% CI: 1.10-1.69).Conclusion: GWG, outside the IOM guidelines has increased risks of APOs among women with GDM, implying that careful surveillance for GWG during different stages of pregnancy is warranted.

Adverse Pregnancy

AbstractBoth inadequate and excessive gestational weight gain (GWG) have been shown to increase the risk of adverse pregnancy outcomes, but the risk profiles of GWG rate are unclear. We aimed to examine the associations between GWG rate in the second/third trimester and a spectrum of pregnancy outcomes. This study consisted of 14 219 Chinese rural nulliparous women who participated in a randomised controlled trial of prenatal micronutrient supplementation during 2006–2009. The outcomes included stillbirth, neonatal and infant death, preterm birth, macrosomia, low birth weight (LBW) and large and small for gestational age (LGA and SGA, respectively). GWG rate was divided into quintiles within each BMI category. Compared with women in the middle quintile, those in the lowest quintile had higher risks of neonatal death (adjusted OR 2·27; 95 % CI 1·03, 5·02), infant death (adjusted OR 1·85; 95 % CI 1·02, 3·37) and early preterm birth (adjusted OR 2·33; 95 % CI 1·13, 4·77), while those in the highest quintile had higher risks of overall preterm birth (adjusted OR 1·28; 95 % CI 1·04, 1·59), late preterm birth (adjusted OR 1·25; 95 % CI 1·00, 1·56), LBW (adjusted OR 1·48; 95 % CI 1·02, 2·15), macrosomia (adjusted OR 1·89; 95 % CI 1·46, 2·45) and LGA (adjusted OR 1·56; 95 % CI 1·31, 1·85). In conclusion, very low and very high GWG rates in the second/third trimester appear to be associated with adverse pregnancy outcomes in Chinese nulliparous women, indicating that an appropriate GWG rate during pregnancy is necessary for neonatal health.

ObjectiveTo study the associations between neighbourhood deprivation and fetal growth, including growth in the first trimester, and adverse pregnancy outcomes.DesignProspective cohort study.SettingThe Netherlands, Rotterdam.Participants8617 live singleton births from the Generation R cohort study.ExpositionLiving in a deprived neighbourhood.Main outcome measuresFetal growth trajectories of head circumference, weight and length.Secondary outcomes measuresSmall-for-gestational age (SGA) and preterm birth (PTB).ResultsNeighbourhood deprivation was not associated with first trimester growth. However, a higher neighbourhood status score (less deprivation) was associated with increased fetal growth in the second and third trimesters (eg, estimated fetal weight; adjusted regression coefficient 0.04, 95% CI 0.02 to 0.06). Less deprivation was also associated with decreased odds of SGA (adjusted OR 0.91, 95% CI 0.86 to 0.97, p=0.01) and PTB (adjusted OR 0.89, 95% CI 0.82 to 0.96, p=0.01).ConclusionsWe found an association between neighbourhood deprivation and fetal growth in the second and third trimester pregnancy, but not with first trimester growth. Less neighbourhood deprivation is associated with lower odds of adverse pregnancy outcomes. The associations remained after adjustment for individual-level risk factors. This supports the hypothesis that living in a deprived neighbourhood acts as an independent risk factor for fetal growth and adverse pregnancy outcomes, above and beyond individual risk factors.

Abstract Background The association between bacteriuria and adverse pregnancy outcomes has been extensively described. The current practice of screening all pregnant women for bacteriuria is challenged by recent studies. We aimed to evaluate pregnancy outcomes among women with a positive urine culture, to assess the significance of positive urinary nitrites in this setting. Methods This was a retrospective cohort study at the emergency department (ED) of the Helen Schneider Hospital for Women, Israel, during 2014–2018. This included all gravida women >18 years old within the 20th week of pregnancy or above, admitted to the ED with diverse complains, who had urinalysis collected and subsequently had a positive urine culture. Clinical and obstetric characteristics were stratified by positive vs. negative nitrites in urinalysis. The primary outcome was premature delivery, and the secondary outcomes were a composite outcome of all recorded pregnancy complications and the significance of urinalysis in predicting urinary tract infection (UTI). Results Overall, 874 pregnant women with a positive urine culture were included. Of them, 721 (79%) patients had a negative nitrite in their urine exam (NNU-group) and 153 (21%) had a positive nitrite in their urine exam (PNU-group). Escherichia coli was the most common pathogen, with significantly higher rates of growth in the PNU-group vs. NNU-group [129 (84.3%) vs. 227 (38.4%), P < 0.001]. Premature delivery was recorded with no association of symptomaticity or nitrite status. Among symptomatic women with classic symptoms of UTI, PNU was significantly associated with decreased risk for major peripartum complications [odds ratio (OR) with 95% confidence interval (CI) of 0.22 (0.05–0.94)]. Conclusion Our findings support that PNU among symptomatic pregnant women with UTI-related symptoms was associated with lower risk of developing major adverse obstetrical outcomes.

ObjectiveTo assess the associations of gestational weight gain (GWG) in early and late pregnancy with subsequent risks of adverse pregnancy outcomes in Chinese women.DesignProspective cohort study.SettingShanghai, China.ParticipantsWe studied 2630 nulliparous singleton pregnant women with complete data on weight gain in early (≤17 weeks of gestation) and late (>17 weeks) pregnancy in the Shanghai Birth Cohort.MethodsGWG was standardised into z-scores by gestational age and categorised as low (z-score <−1), normal (−1 to +1) and high (>1). The adjusted relative risks (aRRs) and 95%CIs were estimated through log-binomial regression models. Interaction effects between GWG and some other adjustment factors were tested, further stratified analyses were performed separately where interaction terms were significant.Outcome measuresAdverse maternal and neonatal outcomes.ResultsIndependent from GWG in late pregnancy, higher GWG in early pregnancy was associated with higher risks of gestational diabetes mellitus (aRR: 1.66; 95% CI: 1.11 to 2.48), caesarean section (aRR: 1.21; 95% CI: 1.05 to 1.39) and prolonged hospitalisation (aRR: 1.56; 95% CI: 1.03 to 2.38). Higher GWG in late pregnancy was independently associated with higher risks of caesarean section (aRR: 1.24; 95% CI: 1.09 to 1.41), large for gestational age (aRR: 2.01; 95% CI: 1.50 to 2.7) and macrosomia (aRR: 1.90; 95% CI: 1.30 to 2.78). In addition, the risk of gestational hypertension increased significantly with increased total GWG (aRR: 1.78; 95% CI: 1.14 to 2.76). The effects of GWG in late pregnancy on maternal and neonatal outcomes were significantly different between the women bearing a female and the women bearing male fetus.ConclusionThe GWG associations with adverse pregnancy outcomes differ at early and late pregnancy, and there may be effect modification by fetal sex in the association of GWG in late pregnancy with some pregnancy outcomes.
