Association between gestational weight gain, birth weight classification, and type of treatment in diabetic mothers

Background: In normal pregnancy, variable amount of weight gain is a constant phenomenon. The study aims to find an association between gestational weight gain and fetomaternal outcome. GWG (using institute of medicines guidelines meant for US population) and pregnancy outcomes among Asian Indians across different BMI categories (according to WHO Asia Pacific BMI cut points) were studied.Methods: 300 women were split into the three groups based on their gestational weight gain. Namely, below recommended GWG, recommended GWG and above recommended GWG group. Comparison of various fetomaternal outcomes was done between these groups.Results: In women, who had higher than recommended GWG, 30.5% developed GDM, 23.2% had gestational hypertensive disorder, 36.6% developed hypothyroidism, 12.2% had pre-term birth and 15.9% had low birth weight. In recommended GWG category, these were 5.4%, 4.5%, 30.6%, 7.2% and 17.1% respectively; and in below recommended category, these were 14%, 1.9%, 22.4%,12.1% and 24.3% respectively.Conclusions: GWG generally follows the BMI pattern at the time of entering into pregnancy, higher the BMI more the GWG. More GWG was associated with GDM, Gestational hypertensive disorders and poor APGAR at birth. Below recommended GWG was associated with higher occurrence of GDM. No statistical correlation, between GWG and mode of delivery, NICU stay, preterm birth and birth weight was observed. Larger study is required to establish the applicability of IOM Guidelines for GWG on Indian women.

Abstract Objective To determine the association between total gestational weight gain and perinatal outcomes. Study Design Data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be (NuMoM2b) study were used. Total gestational weight gain was categorized as inadequate, adequate, or excessive based on the 2009 Institute of Medicine guidelines. Outcomes examined included hypertensive disorders of pregnancy, mode of delivery, shoulder dystocia, large for gestational age or small for-gestational age birth weight, and neonatal intensive care unit admission. Results Among 8,628 women, 1,666 (19.3%) had inadequate, 2,945 (34.1%) had adequate, and 4,017 (46.6%) had excessive gestational weight gain. Excessive gestational weight gain was associated with higher odds of hypertensive disorders (adjusted odds ratio [aOR] = 2.05, 95% confidence interval [CI]: 1.78–2.36) Cesarean delivery (aOR = 1.24, 95% CI: 1.09–1.41), and large for gestational age birth weight (aOR = 1.49, 95% CI: 1.23–1.80), but lower odds of small for gestational age birth weight (aOR = 0.59, 95% CI: 0.50–0.71). Conversely, inadequate gestational weight gain was associated with lower odds of hypertensive disorders (aOR = 0.75, 95% CI: 0.62–0.92), Cesarean delivery (aOR = 0.77, 95% CI: 0.65–0.92), and a large for gestational age birth weight (aOR = 0.72, 95% CI: 0.55–0.94), but higher odds of having a small for gestational age birth weight (aOR = 1.64, 95% CI: 1.37–1.96). Conclusion Both excessive and inadequate gestational weight gain are associated with adverse maternal and neonatal outcomes.

Abstract Background Japan has an exceptionally high proportion of low-weight births and underweight women. It has been suggested that an appropriate increase in gestational weight gain (GWG) for underweight women will help to prevent low birth weight. The current strategy aims to raise the desired value of GWG equally for all pregnant women within the underweight category. However, it remains elusive whether or not the relationship between GWG and birth weight for gestational age (BW/GA) are uniformly equivalent for all the women. Methods We performed a retrospective cohort analysis of women who delivered their newborns at Tokyo Medical and Dental University Hospital from 2013 to 2017. First, in order to examine the direct effect of an increase or decrease in GWG on BW/GA, we analyzed the correlation between inter-pregnancy differences in GWG and BW/GA using a sub-cohort of women who experienced two deliveries during the study period (n = 75). Second, we dichotomized the main cohort (n = 1114) according to BW/GA to verify our hypothesis that the correlation between GWG and BW/GA differs depending on the size of the newborn. Results The inter-pregnancy difference in BW/GA was not correlated with that of GWG. However, the correlation between BW/GA of siblings was high (r = 0.63, p = 1.9 × 10− 9). The correlation between GWG and BW/GA in women who delivered larger-sized newborns was higher (r = 0.17, p = 4.1 × 10− 5) than that in women who delivered smaller-sized newborns (r = 0.099, p = 1.9 × 10− 2). This disparity did not change after adjustment for pre-pregnancy BMI. The mean birth weight in the dichotomized groups corresponded to percentile 52.0 and 13.4 of the international newborn size assessed by INTERGROWTH-21st standards. Conclusions In our study, GWG was positively correlated with BW/GA for heavier neonates whose birth weights were similar to the average neonatal weight according to world standards. However, caution might be required for low-birth-weight neonates because increased GWG does not always result in increased birth weight.
