Obesity and pregnancy: mechanisms of short term and long term adverse consequences for mother and child

Obesity is the most common medical condition in women of reproductive age. Obesity during pregnancy has short term and long term adverse consequences for both mother and child. Obesity causes problems with infertility, and in early gestation it causes spontaneous pregnancy loss and congenital anomalies. Metabolically, obese women have increased insulin resistance in early pregnancy, which becomes manifest clinically in late gestation as glucose intolerance and fetal overgrowth. At term, the risk of cesarean delivery and wound complications is increased. Postpartum, obese women have an increased risk of venous thromboembolism, depression, and difficulty with breast feeding. Because 50-60% of overweight or obese women gain more than recommended by Institute of Medicine gestational weight guidelines, postpartum weight retention increases future cardiometabolic risks and prepregnancy obesity in subsequent pregnancies. Neonates of obese women have increased body fat at birth, which increases the risk of childhood obesity. Although there is no unifying mechanism responsible for the adverse perinatal outcomes associated with maternal obesity, on the basis of the available data, increased prepregnancy maternal insulin resistance and accompanying hyperinsulinemia, inflammation, and oxidative stress seem to contribute to early placental and fetal dysfunction. We will review the pathophysiology underlying these data and try to shed light on the specific underlying mechanisms.

“…9 Multivitamin use during pregnancy is a key factor in the prophylaxis and management of nutritional deficiencies, although there are concerns related to excessive vitamin and iron consumption as a general vitamin and/or iron prophylaxis among pregnant women. 10 Micronutrient and iron supplements are often recommended by physicians without consideration of the dietary intake or iron status of their patient. During pregnancy, an increased demand may become evident, however in non-deficient pregnant women, little is known about the effects of supplementation.…”

Background: The aim of this study is to examine whether there is any positive impact of prenatal iron and vitamin supplementation on birth weight, and if this practice could be a cause of macrosomia.Methods: A total of 1,838 term pregnant women were included in this study and were divided into four groups: iron group (women having only iron supplementation), vitamin (women using only multivitamins), vitamin+iron (women using both iron and multivitamin preparations), and control group (women having neither iron nor vitamin supplements). Statistical analysis was performed to compare age, gravida, parity, hemoglobin, BMI and birth weight. Groups were compared in terms of macrosomia and correlation analysis carried out between demographics and birth weight.Results: The birth weight was significantly higher in the vitamin group and the vitamin+iron group than in the iron group and the control group. Vitamin supplementation increased the risk of macrosomia 3.9 times, while vitamin+iron usage increased the risk 4.8 times.Conclusions: Uncontrolled use of multivitamins and/or iron supplements may increase tendency for fetal macrosomia. The use of multivitamins and/or iron supplements by pregnant women must take into account maternal age, maternal diet and maternal BMI. Our findings support a reduction in the unnecessary use of vitamin and iron supplements in pregnancy, and a reversal of the trend to start vitamin and iron supplementation without any control. The increasing prevalence of obesity and excessive weight in pregnant women should be a warning against the uncontrolled usage of vitamins and iron during pregnancy.
