Through a collaboration of several studies, it can be determined that maternal nutrition is anextremelyimportant determinant of whether or not a baby will develop metabolic diseases later in life. Meyer BJ, Stewart FM, Brown EA, et al. This study did not assess the influence of directly measured genetic factors to the observed associations.93, Long-term risk of cardiovascular disease for offspring, There is accumulating evidence supporting a link between maternal obesity and offspring obesity and cardiometabolic risk factors.11 Whether or not this translates into long-term increased risk of cardiovascular disease and death for the offspring has been harder to investigate due to a lack of suitable cohorts with available data on maternal weight during pregnancy and with long enough follow-up of the offspring.98 There have only been two published studies reporting death from coronary heart disease.98,99. Pre-conceptual health, parental health status, prenatal care. Obesity, pregnancy, inflammation, and vascular function.

Neonatal brachial plexus injury: comparison of incidence and antecedents between 2 decades. These include being of non-European origin,20 lower pre-gravid levels of physical activity,21 and higher pre-pregnancy BMI.22 In obese pregnancy, insulin resistance is even more marked.23 This may be due to increased levels of TNF-α, IL-6, leptin, and adiponectin, which are thought to contribute to insulin resistance in the non-pregnant state.24 In addition, the relative inability of insulin to suppress whole-body lipolysis results in an increase of plasma free fatty acids25 and exaggerated hyperlipidemia.26 These processes significantly increase fuel available for transport to fetuses of obese mothers.

Kok Grouleff M, Wielsøe M, Berthelsen D, Mulvad G, Isidor S, Long M, Bonefeld-Jørgensen EC. Maternal obesity and its association with an increased risk of childhood and adult obesity among offspring has been well documented.11,91 Macrosomia and excess gestational weight gain are the strongest predictors of higher BMI at 1 year of age, and BMI at 1 year of age is predictive of weight status at ages 5–8 years.92 The effect of obesity during pregnancy on offspring risk of obesity appears to be independent of maternal diabetes.61 The Jerusalem Perinatal Family Follow-up Study showed that maternal BMI was independently and positively associated with increased offspring adiposity at age 32 years,93 and that these associations were significant when separated from “shared environment” and “postnatal lifestyle” factors. Although these data suggest that treatment of gestational diabetes could lower the risk of childhood obesity, a more recent study of 4- to 5-year-old children whose mothers participated in a gestational diabetes treatment trial found no difference in obesity rates between children of women who received treatment for mild gestational diabetes and children of women who did not. Minsart AF, Buekens P, De Spiegelaere M, Englert Y. Neonatal outcomes in obese mothers: a population-based analysis. During normal pregnancy, changes take place in the maternal anatomy, physiology, endocrinology, and metabolism to prepare the mother for labor and delivery, and to provide essential nutrients for fetal growth and development. Higa R, Jawerbaum A. 15. 2011;174(10):1159–1165. ; Multiple pregnancy. In obese pregnancy, the physiological adaptations differ from normal-weight women, reflecting physiology that is characteristic of obesity in the non-pregnant state; these changes are thought to contribute to an increased availability of fuel for fetal growth (Figure 1). Cortisol, which rises exponentially during pregnancy as a result of a dysregulated hypothalamic–pituitary–adrenal axis,27 has actions that include increasing insulin resistance and vasoconstriction. Higher weight at birth is related to decreased maternal amino acid oxidation during pregnancy. Landres IV, Milki AA, Lathi RB. 2011;2011:592408. Shoulder dystocia is an uncommon complication that occurs in 0.6%–1.4% of all vaginal vertex births.75,76 It can lead to bruising, fractured clavicle, transient or permanent brachial plexus injury, and hypoxic brain damage. But beyond that, it also leads to health risks in the young children. Methods Normal BMI women (group N, n = 243; 18.5≤ BMI<25 kg/m2) and obese women (group Ob, n = 253; BMI≥30 kg/m2) were recruited in a prospective study between 15 and 18 weeks of gestation. In fact, research shows that obesity increases the risk of pregnancy-related hypertension (pre-eclampsia) and diabetes, which are the leading causes of maternal death. 2013;29(7):626–631. Furthermore, maternal obesity has been hypothesized to cause harmful effects for the develop-ing baby through "early life programming." 1 (a) ]. Birth weight and risk of neuroblastoma: a meta-analysis. In the non-pregnant state, obesity is associated with lower protein synthesis when compared with lean women, with no difference in protein oxidation.34 Visceral lean mass is positively correlated with maternal protein turnover.30 It has therefore been suggested that the anabolic response to pregnancy may be impaired in obese women, and that there may be mechanisms to limit fetal growth in a hyperinsulinemic and glucose-rich environment.35 However, a recent study found that activity of amino acid transporter system A in the placenta was positively correlated with birth weight.36 Furthermore, physiological concentrations of IL-6 and TNF-α have also been shown to stimulate the activity of amino acid transporter system A.37 It has been suggested that in maternal obesity, the increased levels of IL-6 and TNF-α in the placenta could stimulate system A transporter activity further, thus increasing amino acid transport to the fetus.38 Taken together, these data suggest that increased placental amino acid transport may contribute to fetal overgrowth in obese pregnancy. All women were submitted to a 75g oral glucose tolerance test in the . Ahlgren M, Wohlfahrt J, Olsen LW, Sorensen TI, Melbye M. Birth weight and risk of cancer. Maternal obesity and its association with offspring insulin resistance (which is a precursor for type 2 diabetes) has been reported at up to 20 years of age. Registered in England and Wales. For the obstetric population examined in this study, with 23.4% overweight and 16.0% obesity in early pregnancy, the estimated proportions of adverse pregnancy outcomes attributable to maternal overweight and obesity (PAFs) were 16.3% for extreme PTB, 25.2% for LGA infants, 6.5% for admission to SCN/NICU, 38.1% for pre-existing diabetes, 29.3% .

BMJ. Later data showing that higher birth weight is also associated with obesity, diabetes, and other adult diseases has helped extend this concept into the “developmental origins hypothesis,” which encompasses the preconception period as well as many critical periods of fetal and infant development.

Exp Physiol. The concept of the developmental origins of disease has broadened to incorporate elements of all current hypotheses discussed as well as postnatal effects ().In terms of programming of human obesity, it is clear that both maternal genes and environment (particularly lifestyle and diet) have an influence on maternal obesity which is commonly associated with maternal insulin resistance.
