“…In addition to maternal pre‐pregnancy obesity, unsuitable gestational weight gain (GWG) may profoundly impact mother‐infant health, in both the short and the long term 3,4,6‐10 . Insufficient GWG in association with an elevated risk of PTB and intrauterine growth restriction, but excessive GWG may cause macrosomic infants, cesarean section, as well as childhood obesity.…”

“…health, in both the short and the long term. 3,4,[6][7][8][9][10] Insufficient GWG in association with an elevated risk of PTB and intrauterine growth restriction, but excessive GWG may cause macrosomic infants, cesarean section, as well as childhood obesity. The Institute of Medicine (IOM) has formulated GWG guidelines based on prepregnancy body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters), 11 to minimally lower the negative health consequences for mother and fetus of deficient or excessive GWG.…”

Objective To evaluate the relationships of pre‐pregnancy body mass index (BMI) and gestational weight gain (GWG) trajectory with adverse perinatal outcomes (APOs). Methods A retrospective cohort study was conducted in China, and 12 855 women who had a singleton birth were included. The WHO classification categorized pre‐pregnancy BMI, and five GWG trajectories were identified using the latent class growth model. Results The adjusted odds ratios for the risks of cesarean delivery, preterm birth, and large‐for‐gestational‐age (LGA) infant were significantly higher in women with whoe were overweight or obese pre‐pregnancy, but were lower in underweight (except preterm birth) than in normal weight women. Five GWG trajectories were identified: (1) retaining GWG (6.6 kg), (2) moderately slow GWG (10.5 kg), (3) moderate GWG (13.7 kg), (4) moderately fast GWG (16.3 kg), and (5) rapid GWG (19.8 kg). Compared with women in trajectory 3, the risks of cesarean delivery and LGA increase by about 35%–96% for the women in trajectory 4 or 5, whereas the women in trajectory 1 or 2 are inclined to have a higher risk of small for gestational age, but lower risk of LGA. Association of GWG trajectory with APOs varies across pre‐pregnancy BMI subgroups. Conclusion This study highlights the influence of inappropriate pre‐pregnancy maternal weight and GWG trajectories on the risk of APOs.

“…In fact, abnormal weight gain has adverse effects for both matrix and fetus [ 2 , 3 ]. In clinical practice, body mass index (BMI) and weight gain during pregnancy are used for measuring maternal nutritional conditions and fetal growth [ 4 ]. In recent years, the increase of BMI before pregnancy and during pregnancy increases significantly, which results in an increased incidence of hypertensive disorder in pregnancy (HDP) and abnormal glucose and lipid metabolism and affects the growth and gestational age of the fetus [ 5 – 7 ].…”

Objective. The increase of BMI before pregnancy and during pregnancy will lead to hypertensive disorder in pregnancy (HDP) and abnormal glycolipid metabolism, as well as increase the risk of neonatal weight abnormalities and adverse pregnancy outcome. This study retrospectively analyzed the clinical data of 358 women who were admitted to the obstetrics department of our hospital from January 2018 to July 2019. And the relationship between prepregnancy BMI, BMI increase during pregnancy and delivery methods, postpartum hemorrhage, neonatal weight, premature delivery, neonatal asphyxia, gestational diabetes mellitus (GDM), and hypertension during pregnancy (HDP) was observed and compared. The results show that both high BMI before pregnancy and excessive weight gain during pregnancy can lead to the incidence of abnormal birth weight and adverse birth outcome increase. Therefore, in order to reduce the incidence of neonatal weight abnormalities and adverse birth outcomes and to prevent the adverse effects during pregnancy and postpartum, clinically, obese women should be guided to eat according to reasonable diet and exercise to control their weight.

“…Nevertheless, another assumption is the impact of weight loss after such an operation on the prevalence of hypertensive disorders and PE as the condition is a main cause of fetal growth restriction. Weight loss after GB may be a reason for the lower birth weight discordance between twin pregnancies after GB and the control group as lower prevalence of PE after GB may counterbalance the degree of fetal birth weight discordance [26, 29, 30]. This positive effect of a decrease of inter-twin birth weight discordance may be caused by less release of antiangiogenic and inflammatory factors through the placenta and subsequently a better cytotrophoblast migration and uterine spiral artery remodeling and therefore better placentation and blood flow distribution [31].…”

Fetal Growth and Adipose Fat Tissue Trajectories in Twin Pregnancies after Gastric Bypass Surgery

et al. 2021

Introduction: Previous studies demonstrated a continues decline in fetal growth throughout singleton pregnancy after bariatric surgery. However, intrauterine growth in twin pregnancy is subjected to further underlying processes. This study was to investigate the longitudinal assessment of fetal biometry and abdominal fat thickness of twin pregnancies conceived after gastric bypass surgery and compare them to BMI-matched and obese controls. Materials and methods: We retrospectively assessed ultrasound data of 30 women with dichorionic-diamniotic twin pregnancy (11 women after gastric bypass surgery, 9 obese mothers with pregestational BMI ≥ 30 kg/m² and 10 BMI and age matched controls). We assessed fetal growth parameters including fetal subcutaneous adipose tissue thickness (FSCTT) as well as newborn biometry after delivery. Patient characteristics were obtained from the medical records. Results: The rise in FSCTT curves was markedly slower in twin offspring of women with history of gastric bypass as compared to offspring of obese mothers and offspring of BMI matched controls. Hence, FSCTT was significantly decreased in gastric bypass offspring as compared to both control groups at 34 weeks of gestation. Also, growth curves of abdominal circumference were decreased in offspring of gastric bypass patients as compared to obese mothers. Infants of mothers with history of gastric bypass showed significantly lower birth weight percentiles compared to newborns of obese mothers (27.2 vs 48.8 pct, p=0.025). There was no significant difference in inter twin birth weight difference between offspring of gastric bypass (median: 9.9%, IQR: 6.5 to 20.0) vs. obese (median: 14.6%, IQR: 8.2 to 21.6) and BMI matched controls (median: 9.0%, IQR: 6.3 to 12.6, p=0.714). Conclusions: In summary, intrauterine growth delay in twin pregnancies after GB is assumed to be a multifactorial event with altered metabolism as the most important factor. However, special attention must be paid to the particularity of twin pregnancies as they seem to be subject to other additional mechanism.

The association between weight gain during pregnancy and intertwin delivery weight discordance using 2011–2015 birth registration data from the USA

Abstract: Twin pregnancies with maternal weight gain of approximately 25 kg demonstrated the lowest risk of developing intertwin delivery weight discordance, while inadequate weight gain was a risk factor for delivery weight discordance in all pre-pregnancy body mass index categories.
