The metabolic syndrome consists of a combination of risk factors that include abdominal obesity, atherogenic dyslipidaemia, hypertension and insulin resistance. It increases the risk of cardiovascular disease and type 2 diabetes. The increased risk of cardiovascular disease is higher in women than in men. The first manifestation of metabolic syndrome may occur in pregnancy presenting as gestational diabetes or preeclampsia. Both conditions are associated with increased insulin resistance. Also metabolic syndrome is more common in polycystic ovarian syndrome. It has been suggested that there is a metabolic syndrome resulting from the menopause due to estrogen deficiency, as many of the risk factors are more prevalent in postmenopausal women. Also estrogen replacement improves insulin sensitivity and reduces the risk of diabetes. The key elements in managing the metabolic syndrome are weight reduction, increasing physical activity and diet modification. If blood pressure, lipid and glycaemic control are not achieved through these interventions then pharmacological therapy will be required.

The authors compared postpartum adiponectin levels among women with prior pregnancy-induced disturbances and assessed their association with homeostasis model assessment for insulin resistance (HOMA-IR), the metabolic syndrome (MS), and the Framingham risk score (FRS). Women delivering in 1998 through 2001 and who had gestational diabetes mellitus (n=22), gestational hypertension (n=32), or preeclampsia (n=34) were examined 1 to 2 years after delivery and were grouped-matched to controls (n=29) by age and prepregnancy body mass index. HOMA-IR was increased, adiponectin values were decreased, and there was a higher MS prevalence in women with prior gestational diabetes mellitus (all P<.05). Adiponectin levels were inversely related to HOMA-IR (r=-0.45; P<.0001) and FRS (r=-0.25; P=.007), and a significant trend for decreasing adiponectin values with increased number of MS components was noted (P trend <.0001). Adiponectin concentration remained a significant correlate of FRS and MS irrespective of pregnancy history; a concentration <10.5 microg/mL provided the optimal cutoff to distinguish those with or without MS. Thus, a lower postpartum adiponectin concentration identifies women at increased cardiovascular risk regardless of pregnancy history.

Although clustering of cardiovascular risk factors is unquestionable, the importance of the "metabolic syndrome" as a distinct cardiovascular risk marker has been debated recently. In the authors' previous report a high frequency of glucose intolerance was described 8 years after a pregnancy complicated by gestational diabetes, often associated with other unfavorable metabolic parameters. In the present study the objective was to estimate the prevalence of metabolic syndrome in a cohort of previously gestational diabetes women, using different diagnostic criteria, 4 years after delivery. Those data were compared to a control group of 39 women with normal glucose tolerance during pregnancy. Irrespective of the criteria used, metabolic syndrome was found more frequently among women with prior gestational diabetes. The prevalence of metabolic syndrome increased by degree of deterioration of glucose tolerance in the prior gestational diabetes group. Overweight women in both group had 10-fold increased risk of metabolic syndrome compared to normal-weight women. According to our results a clustering of cardiovascular risk factors might be observed in previous gestational diabetes women, 4 yrs after delivery. These data highlight the importance of regular follow-up of these women, and the possible advantage of early and aggressive treatment of each component of metabolic syndrome.

The role of micronutrients in the etiology of type 2 diabetes is not well established. Several lines of evidence suggest that iron play may a role in the pathogenesis of type 2 diabetes. Iron is a strong pro-oxidant and high body iron levels are associated with increased level of oxidative stress that may elevate the risk of type 2 diabetes. Several epidemiological studies have reported a positive association between high body iron stores, as measured by circulating ferritin level, and the risk of type 2 diabetes and of other insulin resistant states such as the metabolic syndrome, gestational diabetes and polycystic ovarian syndrome. In addition, increased dietary intake of iron, especially that of heme iron, is associated with risk of type 2 diabetes in apparently healthy populations. Results from studies that have evaluated the association between genetic mutations related to iron metabolism have been inconsistent. Further, several clinical trials have suggested that phlebotomy induced reduction in body iron levels may improve insulin sensitivity in humans. However, no interventional studies have yet directly evaluated the effect of reducing iron intake or body iron levels on the risk of developing type 2 diabetes. Such studies are required to prove the causal relationship between moderate iron overload and diabetes risk.

The prevalence of both obesity and gestational diabetes mellitus (GDM) is rising worldwide. The complications of diabetes affecting the mother and fetus are well known. Maternal complications include preterm labor, pre-eclampsia, nephropathy, birth trauma, cesarean section, and postoperative wound complications, among others. Fetal complications include fetal wastage from early pregnancy loss or congenital anomalies, macrosomia, shoulder dystocia, stillbirth, growth restriction, and hypoglycemia, among others. The presence of obesity among diabetic patients compounds these complications. The above-mentioned short-term complications can be mediated by achieving the desired level of glycemic control during pregnancy. However, GDM during pregnancy is associated with increased risk of early obesity, type 2 diabetes during adolescence and the development of metabolic syndrome in early childhood. Additionally, GDM is a marker for the development of overt type 2 diabetes and metabolic syndrome for the mother in the early future.

Foetal growth from conception to birth is a complex process predetermined by the genetic configuration of the foetus, the availability of nutrients and oxygen to the foetus, maternal nutrition and various growth factors and hormones of maternal, foetal and placental origin. Maintenance of the optimal foetal environment is the key factor of the future quality of life. Such conditions like inadequate nutrition and oxygen supply, infection, hypertension, gestational diabetes or drug abuse by the mother, expose the foetus to nonphysiological environment. In conditions of severe intrauterine deprivation, there is a potential loss of structural units within the developing organ systems affecting their functionality and efficiency. Extensive human epidemiologic and animal model data indicate that during critical periods of prenatal and postnatal mammalian development, nutrition and other environmental stimuli influence developmental pathways and thereby induce permanent changes in metabolism and chronic disease susceptibility. The studies reviewed in this article show how environmental factors influence a diverse array of molecular mechanisms and consequently alter disease risk including diseases such as metabolic syndrome and cardiovascular diseases, insulin resistance and diabetes mellitus, neuropsychiatric disorders, osteoporosis, asthma and immune system diseases.

Gestational diabetes mellitus (GDM) is a common pregnancy complication with increased maternal and perinatal morbidity. However, significant long-term morbidity also exists for the mother and offspring. Women with previous GDM have a very high risk of developing overt diabetes, primarily type 2 diabetes, later in life. Moreover, the risk of the metabolic syndrome is increased 3-fold in these women. Their offspring have an 8-fold risk of diabetes/prediabetes at 19-27 years of age. Thus, GDM is part of a vicious circle which increases the development of diabetes in the coming generations.

Asians adopting a modern lifestyle have a higher risk of diabetes than their white counterparts living in high-income countries. Asian ethnicity is an independent risk factor for gestational diabetes mellitus (GDM), which is associated with a 2-fold increased risk of diabetes. In this burgeoning epidemic of diabetes, 40 million people in China are affected, with the most rapid rate of increase in disease prevalence in the young to middle-aged group. This rising trend of young onset diabetes is largely driven by the rising prevalence of childhood obesity/metabolic syndrome. In Asia, both low and high birth weights are independent risk factors for diabetes and metabolic syndrome. Apart from the high prevalence of maternal history of diabetes in women with diabetes, the metabolic milieu of GDM may have long-term effects on the metabolic profile and future risk of diabetes in the offspring. This complex interplay between environmental, genetic, and perinatal factors puts both mothers with a history of GDM and their offspring at risk of diabetes and metabolic syndrome, thus setting up a vicious cycle of "diabetes begetting diabetes." Given the public health burden of diabetes in low-income nations such as China, there is an urgent need to design and implement large-scale awareness and intervention programs targeted at these mother-offspring pairs to interrupt this transgenerational effect of diabetes and the socioeconomic and humanistic impacts.

Gestational diabetes mellitus (GDM) is defined as glucose intolerance with onset or first recognition during pregnancy. Data from Western countries suggest that the prevalence of GDM is increasing, being almost 10% of pregnancies and probably reflecting the global obesity epidemic. The majority of women with GDM seem to have beta-cell dysfunction that appears on a background of chronic insulin resistance already present before pregnancy. In less than 10% of GDM patients, defects of beta-cell function can be due to autoimmune destruction of pancreatic beta-cells, as in type 1 diabetes, or caused by monogenic mutations, as in several MODY subtypes. Diagnostic criteria for GDM vary worldwide and there are no clear-cut plasma glucose cut-off values for identifying women at a higher risk of developing macrosomia or other fetal complications. Because the oral glucose tolerance test (OGTT) is restricted to high risk individuals, 40% of GDM cases are left undiagnosed. Therefore, in high risk populations almost universal screening is recommended; only women considered to have very low risk do not need screening. Diet and exercise are the key elements in the treatment of GDM. If necessary, either insulin, certain oral hypoglycemic agents or combinations can be used to achieve normoglycemia. After delivery, women with GDM and their offspring have an increased risk for developing the metabolic syndrome and type 2 diabetes. Thus, pregnancy may act as a "stress test", revealing a woman's predisposition to T2D and providing opportunities for focused prevention of important chronic diseases.

The association between maternal gestational diabetes (GDM) and manifestations of metabolic syndrome among Caucasian adolescents was studied with data from the population-based Northern Finland 1986 Birth Cohort. This is a longitudinal cohort study from early pregnancy until offspring age 16 years and includes data from a risk group-based GDM screen of pregnant mothers by an oral glucose tolerance test. Metabolic outcomes were compared between the offspring of women with GDM (OGDM; n = 95) and reference group offspring (n = 3,909). The prevalence of overweight was significantly higher in the OGDM group (18.8 vs. 8.4%; P < 0.001) than in the reference group. The median body mass index (20.8 vs. 20.2 kg/m(2), 95% confidence interval (CI) for the percentage difference adjusted for sex: 3.5%, 9.5%), waist circumference (73.3 vs. 71.5 cm, 95% CI: 3.2%, 7.5%), and fasting insulin (10.20 vs. 9.30 milliunits/L, 95% CI: 5.9%, 26.0%) were higher, and homeostatic model assessment-insulin sensitivity (74.7 vs. 82.3, 95% CI: -20.6%, -5.4%) was lower in the OGDM group. These differences were similar after an additional adjustment for birth weight and gestational age. The differences in waist circumference, insulin, and homeostatic model assessment-insulin sensitivity were attenuated but remained statistically significant after additional adjustment for body mass index at 16 years. These findings highlight the importance of prevention strategies among children born to women with GDM.
