Neonatal iron status is impaired by maternal obesity and excessive weight gain during pregnancy

AbstractIntroductionMaternal obesity is associated with an increased risk for adverse perinatal outcomes. Obesity is also associated with a chronic inflammatory state and metabolic derangements that affect the newborn. The additional use of cardiopulmonary bypass during the neonatal period could impact the systemic inflammatory response in the immediate postoperative period that manifests as cardiac depression and multi-organ dysfunction. This study aimed to determine the association of maternal obesity and excessive weight gain during pregnancy with the immediate postoperative morbidity of neonatal patients undergoing cardiopulmonary bypass.MethodsA retrospective review of neonates who underwent cardiopulmonary bypass within the first 30 days of life at our institution between 2011 and 2013 was conducted. Postoperative variables investigated included the duration of length of mechanical ventilation, length of stay in the ICU, peak vasoactive inotrope scores, and peak lactate level. Maternal obesity was defined as 1st trimester body mass index ⩾30 kg/m2. Excessive weight gain was defined as ⩾12 kg gained during pregnancy. In order to determine the association between maternal obesity or excessive weight gain and postoperative variables, we used multiple linear regression, adjusting for birth weight and risk adjustment for congenital heart surgery score.ResultsRecords from 58 mother–baby dyads were examined. After controlling for birth weight and risk adjustment for congenital heart surgery score, there were no significant associations between maternal obesity and excessive weight gain during pregnancy versus all postoperative outcomes measured.ConclusionDespite the known negative impact of maternal obesity on perinatal outcomes, we were unable to find associations between maternal obesity and excessive weight gain during pregnancy versus postoperative outcomes.

Weight Gain During Pregnancy

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.
