Abstract Background This study aims to explore the relationships between pre-pregnancy body mass index (BMI), gestational weight gain (GWG), rate of GWG during the second and third trimesters (GWGrate) and birth weight among Chinese women. Methods Women were enrolled by 24 hospitals in 15 different provinces in mainland China from July 25th, 2017 to 26 November 2018. Pre-pregnancy BMI, GWG and GWGrate were calculated and divided in to different groups. The multinomial logistic regression model and restrictive cubic spline model were used to explore the relationships. Results Of the 3585 participants, women who were underweight, had insufficient GWG or GWGrate had 1.853-, 1850- or 1.524-fold higher risks for delivering small-for-gestational-age (SGA) infant compared with women who had normal BMI, sufficient GWG or GWGrate. Women who were overweight/obese, had excessive GWG or GWGrate had 1.996-, 1676- or 1.673-fold higher risks for delivering large-for-gestational-age (LGA) infant. The effects of GWG and GWGrate on birth weight varied by pre-pregnancy BMI statuses. Dose-response analysis demonstrated L-shaped and S-shaped relationships between pre-pregnancy BMI, GWG, GWGrate and neonatal birth weight. Conclusions Pre-pregnancy BMI, GWG or GWGrate were associated with neonatal birth weight among Chinese women. Both body weight before and during pregnancy should be maintained within the recommendations to prevent abnormal birth weight.

Abstract Objectives The aim of this study was to analyze the interaction between pre-pregnancy body mass index (PP BMI), gestational weight gain (GWG), and newborn outcomes among pregnant mothers in West Sumatera, Indonesia. Methods This VDPM cohort study was conducted from September 2017 to March 2018 in West Sumatra, Indonesia. We obtained 195 healthy mother-infant pairs. GWG status created by comparing PP BMI and GWG guidelines based on the World Health Organization (WHO). Newborn birth weight, birth length, and head circumference were taken immediately after delivery as pregnancy outcomes. SPSS version 20.0 was used to analyze bivariate and multivariate analysis to assess the interaction between PP BMI and gestational weight gain in pregnancy outcomes with adjusting potential confounders. A P-value less than 0.05 was considered as a significant association. Results Of the 195 mother-infant pairs (Mean 29.66 years) included in the main sample, Most of the mothers had 46.7% normal PP BMI with most of them had an inadequate GWG status during pregnancy with 53.3%. Adequate and excessive GWG statuses were 34.4% and 12.3%, respectively. There was a significant association between PP BMI and GWG (p < 0.01). This study had no interaction between PP BMI and GWG to the newborn outcomes (p > 0.05). Adverse newborn outcomes were not statistically significant among groups. However, mothers who had inadequate GWG status may have significant lower birth weight and head circumference compared to normal and excessive GWG status (p < 0.05). Conclusions This study had no interaction between PP BMI and GWG status to newborn outcomes. However, the GWG status associated with newborn outcomes in birth weight and head circumference level. Further prospective studies with a larger number are required to confirm this finding. Funding Sources Indonesian Danone Institute Foundation.

Abstract Background:Considering the potential inappropriateness of the 2009 Institute-of-Medicine criteria to Chinese women, we investigated the associations between pre-pregnancy body-mass-index (BMI), gestational-weight-gain (GWG) and breastfeeding-duration among Chinese women.Methods:This birth-cohort study included 225 mother-child pairs in Shanghai from 2010 to 2012. Mothers were interviewed during mid-to-late pregnancy and at 24-36 months postpartum. Information on pre-pregnancy BMI/GWG and breastfeeding-duration was collected during pregnancy and at 24-36 months postpartum, respectively. Using a data-driven approach based on spline-smoothing-fitting of the data, two-piecewise linear regression models were used to assess the relations between pre-pregnancy BMI, GWG and breastfeeding-duration. Results:Mothers being younger, longer daily working hours, and less time living with children per week were associated with shorter duration (P<0.05). The "inverted-U"-shaped and "flat-then-declining"-shaped associations between pre-pregnancy BMI, GWG and breastfeeding-duration were observed, respectively. Adjusting for related confounders, the increases in pre-pregnancy BMI below and above 22.5 kg/m2 were associated with an increase (P=0.044) and a marginal decrease (P=0.077) in breastfeeding-duration, respectively. One-kilogram increase in GWG was associated with 0.4-month decrease (95% CI: -0.7, -0.1) in breastfeeding-duration when GWG ≥ 17.5 kilograms, however, with nonsignificant changes when GWG <17.5 kilograms. Conclusion:Appropriate pre-pregnancy BMI (around 22.5 kg/m2) and GWG (< 17.5 kilograms) were favorable to sustained breastfeeding.
