The effects of pre-pregnancy body mass index and gestational weight gain on perinatal outcomes in Korean women: a retrospective cohort study

Abstract Background Pre-pregnancy body mass index and gestational weight gain were related to perinatal outcomes. It was not know the changes of pre-pregnancy body mass index, weight gain during pregnancy and its effect on perinatal outcomes in two-child women.Methods This was a retrospective study. Data of single term women delivered in the First Affiliated Hospital of Sun Yat-sen University were collected from July 2017 to June 2018. Gestational weight gain criteria of the American Institute of Medical Research and pre-pregnancy body mass index classes were used to evaluate the effects on pregnancy outcomes.Results A total of 3049 cases were enrolled in the study. Overweight cases was 9.0% and obesity was 2.4%. The weight gain of the two-child women was less than that of primipara(12.4±3.9vs13.3±4.0kg, P<0.001). The proportion of primipara with excessive weight gain was higher compared to two-child women(20.1%versus17.3%, P<0.001). There were 40.0% overweight primipara and 55.2% of two-child women had excessive weight gain. And 40.5% primipara and 54.5% two-child women of obesity had excessive weight gain during pregnancy. Obese primipara increased the risk of pre-eclampsia (aOR2.38, 95%CI 0.76-7.46). And the odds of diabetes mellitus and large for gestational age also increased in this group (aOR3.49, 95%CI 1.46-8.35 and aOR7.65, 95%CI 1.83-31.97, respectively). Two-child women had similar results. Underweight primipara with excessive weight gain increased the pre-eclampsia risk (aOR2.26, 95%CI 0.29-17.46). Normal weight and overweight/obese primipara also had similar results. But in two-child women, only overweight/obesity increased the risk of pre-eclampsia (aOR2.01, 95%CI 0.41-9.98). Underweight two-child women with less weight gain increased the risk of diabetes(aOR2.06, 95%CI 0.43-9.8). Two-child women with overweight/obese increased the odds of LGA even if they had less weight gain(aOR2.58, 95%CI 0.11-63.22). Normal weight primipara and two-child women with overweight and obese with excessive weight gain had similar results. On the other way, underweight primipara with less weight gain increased the risk of SGA(aOR1.74, 95%CI 0.81-3.76).Conclusions Gestational weight gain of two-child women was less than primipara. Overweight/obese women with excessive weight gain of two-child women increased the risk of adverse outcomes.

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.
