Abstract Abstract The study was conducted to evaluate the clinical feasibility of Institute of Medicine (IOM) recommendations on gestational weight gain (GWG) in mainland China. 88,297 singleton pregnancies from a nationwide birth registry study were included. GWG per week was calculated and grouped into within, below and above IOM (IOM) guidelines based on first trimester Chinese body weight index (BMI) status. Univariable and multivariable analyses were performed to determine the relationship between GWG category and perinatal outcomes. We found that excessive GWG was associated with increased risk in pregnancy induced hypertensive disorders (aOR 2.41, 95%CI 2.16-2.69), cesarean section (aOR 1.55, 95%CI 1.47–1.63 for nulliparas, aOR 1.51, 95%CI 1.38–1.65 for multiparas with no prior cesarean section), severe postpartum hemorrhage (aOR 1.15, 95%CI 1.06-1.26), large for gestational neonates (aOR1.76, 95%CI 1.69-1.85) and macrosomia (aOR 1.83, 95%CI 1.72-1.96), while inadequate GWG was correlated with higher risk in placenta abruption (aOR 1.54, 95%CI 1.29-1.85) , fetal distress (aOR 1.19, 95%CI 1.12-1.26), and small for gestational neonates (aOR 1.50, 95%CI 1.41-1.60). Either GWG above or below was associated with increased risk in preterm birth (aOR 1.48, 95%CI 1.38-1.58 for above, aOR 1.47, 95%CI 1.31–1.64 for below), and neonatal asphyxia (aOR 2.28, 95%CI 2.00-2.61 for above, aOR 1.42, 95%CI 1.25-1.61 for below). GWG within IOM recommendations may help prevent various adverse perinatal outcomes and seemed suitable in Chinese population.

Iom Recommendations

Although validated in other parts of the world, the suitability of the U.S. Institute of Medicine (IOM) 2009 recommendations on gestational weight gain (GWG) for Bangladeshi women remains to be examined. We evaluated the association between the weekly rate of weight gain during the second and third trimester of pregnancy, categorized according to IOM recommendations, and adverse perinatal outcomes among 1569 pregnant women with singleton live births in rural Matlab, Bangladesh. Gaining weight at rates below the IOM recommendations was associated with higher odds of preterm birth (adjusted odds ratio (AOR) = 2.0, 95% CI: 1.1–3.6), low birth weight (AOR = 1.4, 95% CI: 1.03–2.0), small-for-gestational-age newborns (AOR = 1.3, 95% CI: 1.04–1.7), and poor neonatal outcome (severe neonatal morbidity or death, AOR = 2.4, 95% CI: 1.03–5.6). A GWG rate above the recommendations was associated with higher odds of cesarean delivery (AOR = 1.7, 95% CI: 1.1–2.6), preterm birth (AOR = 2.2, 95% CI: 1.1–4.4), large-for-gestational-age newborns (AOR = 5.9, 95% CI: 1.5–23.1), and poor neonatal outcome (AOR = 2.7, 95% CI: 1.04–7.0). Our results suggest that the IOM 2009 recommendations on GWG rate during the second and third trimester may be suitable for guiding rural Bangladeshi women in the prenatal period, although the women should aim for rates near the lower bound of the range.

AbstractWe aimed to investigate the optimal range of gestational weight gain (GWG) for Japanese underweight (body mass index <18.5 kg/m2) women using the Japanese Birth Registry System. The study subjects included underweight women who were divided into groups according to the GWG recommendations of the Ministry of Health, Labour and Welfare (MHLW) (9–12 kg): <9.0 kg, group A; 9–12 kg, group B; and >12 kg, group C. The subjects were then classified according to the recommendations of the Institute of Medicine (IOM) (12.7–18.1 kg): <12.7 kg, group D; 12.7–18.1 kg, group E; and >18.1 kg, group F. In total, 148,135 cases were analysed. The frequencies of small for gestational age, preterm delivery, and caesarean delivery were as follows: 19.3%, 22.7%, and 28.5% for group A; 11.7%, 8.7%, and 22.8% for group B; 8.0%, 4.9%, and 21.5% for group C; 15.0%, 14.7%, and 25.2% for group D; 8.0%, 5.3%, and 21.5% for group E; and 7.0%, 5.5%, and 25.0% for group F, respectively. These results indicated that groups C and E had the best outcomes. Therefore, the IOM guidelines seem more appropriate than the MHLW guidelines. Therefore, the MHLW recommended GWG guidelines require revision.

The Impact

Abstract Background. Obesity and gestational diabetes mellitus (GDM) are associated to increased risk of perinatal complications and obesity in the offspring. However, the impact of gestational weight gain (GWG) on maternal and fetal outcomes has led to controversial results. Research design and methods. Retrospective study of 220 women with GDM and pre-pregnancy body mass index (BMI) ≥ 30 kg/m2. Pregnant women were classified according to the Institute of Medicine (IOM) recommendations regarding prior BMI and GWG. We evaluated the impact of GWG on birth weight and perinatal outcomes. Results. Mean maternal age was 34.7±5.3 years. Pre-pregnancy obesity was classified as grade I in 55.3% of cases, grade II in 32.0%, and grade III in 12.7%. GWG was adequate (5-9kg) in 24.2%, insufficient (< 5kg) in 41.8% and excessive (> 9kg) in 34.2%. Birthweight was within normal range in 81.9%, 3.6% were small for gestational age (SGA) and 14.4% were large for gestational age (LGA). Insufficient GWG was associated to a higher rate of SGA offspring, excessive GWG was associated to LGA and adequate GWG to normal birth weight. Conclusion. GWG in women with pre-pregnancy obesity and GDM impacts neonatal birthweight. Insufficient GWG is associated to SGA and excessive GWG is associated to LGA. Women with adequate GWG according to IOM guidelines obtained better perinatal outcomes.

Weight Gain During Pregnancy

Abstract We aim to explore the association between gestational weight gain and adverse events during pregnancy. A retrospective study was conducted to evaluate the perinatal outcomes in singleton women whose weight gain during pregnancy was below, within, or above the 2009 Institute of Medicine's (IOM) guidelines, and delivered between 24 and 42 weeks’ gestation. GWG was derived using weight at delivery minus the pre-pregnancy or first trimester weight. Our results indicated that mothers with low GWG had increased odds of having small-for-gestational-age neonates (adjusted OR 1.202; 95% CI 1.031-1.403), and preterm birth (adjusted OR 2.03; 95% CI 1.769-2.439), but decreased odds of having macrosomia (adjusted OR 0.523; 95% CI 0.24-0.991). Meanwhile, mothers with GWG above the IOM recommendations had higher odds of having hypertensive disease of pregnancy (adjusted OR 2.07; 95% CI 1.314-3.535), gestational diabetes (adjusted OR 1.227; 95% CI 1.038-1.448), cesarean section (adjusted OR 1.34; 95% CI 1.279-1.512), induced labor (adjusted OR 1. 219; 95% CI 1.051-1.409), failure of induced labor (adjusted OR 1.432; 95% CI 1.03-1.992), macrosomia (adjusted OR 1.987; 95% CI 1.384-2.725), and shoulder dystocia (adjusted OR 1.715; 95% CI 1.292-2.18. In conclusion, GWG is an important predictor of adverse maternal and neonatal outcomes during pregnancy.
