Objectives:
This study examines the association between fetal macrosomia (>5,000 g) and pregnancy and birth outcomes.
Methods:
This was a retrospective cohort study using data from the perinatal survey of Lower Saxony, Germany (2001-2009).
Results:
Pregnancies complicated by advanced maternal age (>35 years), elevated BMI (>25.0), and excessive gestational weight gain were significantly more likely to result in macrosomic births. Additionally, pregnancies involving macrosomic fetuses were characterized by prolonged gestation and an increased likelihood of cesarean delivery. Neonates with macrosomia exhibited significantly lower Apgar scores at 1, 5, and 10 min (<7) compared to the control group (<5,000 g), though umbilical artery pH values did not differ significantly between groups.
Conclusions:
These findings highlight the need for targeted prenatal monitoring and risk assessment in pregnancies predisposed to fetal macrosomia.

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
