About this study
Offspring from overweight or obese mothers appear to be at up to 38% increased risk of being admitted to the neonatal intensive care unit than the offspring of mothers with a normal BMI. In terms of Apgar scores at birth, babies of obese mothers have been reported to have a 31% excess risk of having a low Apgar score (defined at <7 at 1 minute) . Infants born to obese mothers demonstrate a spectrum of outcomes, suggesting that there is a complex interplay of factors that defines the precise altered metabolic environment to which the fetus is exposed and that determines the risk of complications
Read the detailed description
The investigators need to improve understanding of the specific molecular factors that contribute either individually or synergistically to detrimental fetal outcomes. Moreover, The investigators need to identify the essential maternal markers that need to be tightly regulated during pregnancy to improve outcomes. Here in, The investigators discuss the influence of maternal obesity and factors associated with the obesogenic intrauterine environment on fetal lung development and respiratory outcomes in offspring at birth importantly, The investigators identify a series of molecular changes encountered during pregnancy that may program the observed respiratory outcomes in clinical practice. The effects of maternal obesity on severe neonatal asphyxia may be partly explained by traumatic labor, which often results from macrosomia. Another consequence of maternal obesity is fetal hyperinsulinemia, which may be related to chronic hypoxia even without diabetes . Other mechanisms that explain the effect of maternal obesity on neonatal asphyxia include lipotoxicity, placental inflammation and vasculopathy, and cord coiling. Evidence has demonstrated altered gene expression in full-term newborns of mothers with obesity, involving dysregulation of brain development, inflammatory and immune signaling, glucose and lipid homeostasis, and oxidative stress

What does the primary outcome measure?
Rate of admission to neonatal observation room (time frame: 6 hours post delivery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Apr 2025.
