Maternal factors associated with fetal growth and birthweight are independent determinants of placental weight and exhibit differential effects by fetal sex. INTRODUCTION: Maternal nutritional and metabolic factors influence the developmental environment of the fetus..
Thereof, what are maternal risk factors?
Pregnant women whose BMI was 25 to 29.9 kg/m2 (overweight) or ≥ 30 kg/m2 (obese) before pregnancy are at risk of maternal hypertension and diabetes, postterm pregnancy, pregnancy loss, fetal macrosomia, congenital malformations, intrauterine growth restriction, preeclampsia, and the need for cesarean delivery.
Additionally, what are the factors of prenatal development? The principal determinants of fetal growth are fetal genotype and in utero environment. Environmental factors include maternal and paternal genetics, maternal size, and the capacity of the placenta to provide nutrients to the fetus.
In this way, what are two factors that affect fetal development?
Factors affecting fetal growth can be maternal, placental, or fetal. Maternal factors include maternal size, weight, weight for height, nutritional state, anemia, high environmental noise exposure, cigarette smoking, substance abuse, or uterine blood flow.
What affects placental growth?
Placental growth precedes birth weight, and previous studies show a positive relationship between placental weight and birth weight [17]. On the one hand, placental weight and placental ratio appear to increase with severe maternal anemia and this effect has been attributed to maternal under nutrition [7,12,18-20].
