Abstract
Type 2 diabetes is now a pandemic and shows no signs of abatement. In this Seminar we review the pathophysiology of this disorder, with particular attention to epidemiology, genetics, epigenetics, and molecular cell biology. Evidence is emerging that a substantial part of diabetes susceptibility is acquired early in life, probably owing to fetal or neonatal programming via epigenetic phenomena. Maternal and early childhood health might, therefore, be crucial to the development of effective prevention strategies. Diabetes develops because of inadequate islet β-cell and adipose-tissue responses to chronic fuel excess, which results in so-called nutrient spillover, insulin resistance, and metabolic stress. The latter damages multiple organs. Insulin resistance, while forcing β cells to work harder, might also have an important defensive role against nutrient-related toxic effects in tissues such as the heart. Reversal of overnutrition, healing of the β cells, and lessening of adipose tissue defects should be treatment priorities.

Abstract
AIMS Maternal diabetes may affect offspring cognitive function. The objective of the study was to evaluate cognitive function and potential predictors hereof in adult offspring of women with Type 1 diabetes. METHODS We conducted a follow-up study of adult offspring of women with Type 1 diabetes (n = 158) and a reference group from the background population (n = 118). The main outcome measure was offspring cognitive function measured by global cognitive score, derived from Raven's Progressive Matrices and three verbal subtests from the Weschler Adult Intelligence Scale. RESULTS Offspring of women with Type 1 diabetes obtained lower global cognitive scores (94.8 vs. 100.0, P = 0.004) than offspring from the background population. When adjusted for confounders, the groups no longer differed significantly (difference 0.4, 95% CI -3.3 to 4.). Positive predictors of cognitive function in offspring of women with diabetes were family social class, parental educational level, maternal diabetes duration, male gender and offspring age, whereas parity ≥ 1 and gestational age < 34 weeks were negative predictors. We found no association with maternal glycaemia during pregnancy or with neonatal hypoglycaemia. CONCLUSIONS Impaired cognitive function in adult offspring of women with Type 1 diabetes compared with the background population apparently reflects differences with respect to well-known confounders. However, harmful effects of maternal hyperglycaemia may be mediated through delivery at < 34 weeks.

Abstract
OBJECTIVES To appreciate, in epidemiological studies, the impact of fetal exposure to gestational diabetes on the long term outcome of the offspring (type 2 diabetes, overweight and obesity, metabolic syndrome and neurological complications). METHODS A systematic search was conducted in Medline between January 1990 and April 2010. Prospective studies (follow-up of the offspring born of mothers with gestational diabetes) and retrospective studies (questionnaire about the parents'history of diabetes in diabetic patients) were searched and analysed. RESULTS The fetal exposure to maternal gestational diabetes is a moderate risk factor for metabolic syndrome in the offspring. But some other perinatal risk factors of metabolic syndrome carry a bigger influence. The influence of genetic factors and maternal overweight may not be easily distinguished from the impact of fetal exposure to gestational diabetes. CONCLUSION It remains uncertain if the control of maternal glycemia alone may be effective and sufficient to prevent the metabolic syndrome in the adult-aged offspring.

Abstract
OBJECTIVE To propose new cutoffs in plasma glucose levels in screening and diagnosis of gestational diabetes mellitus (GDM) in the first trimester of pregnancy. METHODS A 50-gram oral glucose challenge test (GCT) was performed in 1,716 singleton pregnancies at 6-14 weeks' gestation. In those with a positive GCT, a 100-gram glucose tolerance test (GTT) was carried out. The GCT and as necessary the GTT were repeated at 20-30 weeks. The relation of the results of the GCT and GTT at 6-14 weeks to that at 20-30 weeks was examined. RESULTS The diagnosis of GDM was made in 85 cases. In the GCT, there was a significant association between 1-hour plasma glucose levels at 6-14 weeks and at 20-30 weeks (r = 0.558, p < 0.0001), and in all cases of GDM, the level was 130 mg/dl or more at 6-14 weeks and 140 mg/dl or more at 20-30 weeks. In the GTT, the plasma glucose 1, 2 and 3 h after the 100-gram glucose load at 6-14 weeks was, respectively, 18, 29 and 35% lower than at 20-30 weeks. CONCLUSION Effective diagnosis of GDM in the first trimester can be achieved by lowering the GCT and GTT plasma glucose cutoffs.

Abstract
The current approach to prenatal care, which involves visits at 16, 24, 28, 30, 32, 34 and 36 weeks and then weekly until delivery, was established 80 years ago. The high concentration of visits in the third trimester implies, firstly, that most complications occur at this late stage of pregnancy and, secondly, that most adverse outcomes are unpredictable during the first or even second trimester. This review presents evidence that many pregnancy complications can now be predicted at an integrated first hospital visit at 11-13 weeks by combining data from maternal characteristics and history with findings of biophysical and biochemical tests. It is therefore proposed that the traditional pyramid of care should be inverted with the main emphasis placed in the first rather than third trimester of pregnancy.

Abstract
The newly proposed criteria for diagnosing gestational diabetes will result in a gestational diabetes prevalence of 17.8%, doubling the numbers of pregnant women currently diagnosed. These new diagnostic criteria are based primarily on the levels of glucose associated with a 1.75-fold increased risk of giving birth to large-for-gestational age infants (LGA) in the Hyperglycemia Adverse Pregnancy Outcome (HAPO) study; they use a single OGTT. Thus, of 23,316 pregnancies, gestational diabetes would be diagnosed in 4,150 women rather than in 2,448 women if a twofold increased risk of LGA were used. It should be recognised that the majority of women with LGA have normal glucose levels during pregnancy by these proposed criteria and that maternal obesity is a stronger predictor of LGA. The expected benefit of a diagnosis of gestational diabetes in these 1,702 additional women would be the prevention of 140 cases of LGA, 21 cases of shoulder dystocia and 16 cases of birth injury. The reproducibility of an OGTT for diagnosing mild hyperglycaemia is poor. Given that (1) glucose is a weak predictor of LGA, (2) treating these extra numbers has a modest outcome benefit and (3) the diagnosis may be based on a single raised OGTT value, further debate should occur before resources are allocated to implementing this change.

Abstract
Endothelial dysfunction has been observed systemically in women with gestational diabetes (GDM). Important cardiovascular adaptations occur during pregnancy, including enhanced endothelium-dependent vasodilation in systemic and uterine arteries, which are necessary to ensure the health of both mother and fetus. The effects of GDM, however, on uterine artery function and the possible mechanisms that mediate endothelial dysfunction remain unknown. The aim of this study was to utilize a mouse model of GDM to investigate (a) effects on uteroplacental flow, (b) endothelial function of uterine and mesenteric arteries, and (c) possible mechanisms of any dysfunction observed. Pregnant mice heterozygous for a leptin receptor mutation (Lepr(db) (/+); He) spontaneously develop GDM and were compared to wild-type (WT) mice at day 18.5 of gestation. Uterine artery flow was assessed using ultrasound biomicroscopy. Uterine and mesenteric artery function was assessed using wire myography. Arterial superoxide production was measured using oxidative fluorescence microphotography. In vivo uteroplacental perfusion was impaired in mice with GDM, indicated by a significant increase in uterine artery resistance index. Maximal endothelium-dependent relaxation to methacholine was significantly impaired in mesenteric arteries from mice with GDM, while sensitivity was significantly reduced in uterine arteries. Both uterine and mesenteric arteries from mice with GDM exhibited a greater dependence on nitric oxide and increased superoxide production compared with those from mice with a healthy pregnancy. A significant source of superoxide in GDM mice was uncoupled nitric oxide synthase. These changes may contribute to the development of some of the fetal and maternal complication associated with GDM.

Abstract
OBJECTIVES We investigated the contribution of gestational diabetes mellitus (GDM) to the historic epidemic of type 2 diabetes mellitus (T2DM) in Saskatchewan. METHODS We constructed a population-level simulation model of the inter- and intragenerational interaction of GDM and T2DM for the period 1956 to 2006. The model was stratified by gender, ethnicity, and age; parameterized with primary and secondary data; and calibrated to match historic time series. Risk of diabetes was sigmoidally trended to capture exogenous factors. RESULTS Best-fit calibrations suggested GDM may be responsible for 19% to 30% of the cases of T2DM among Saskatchewan First Nations people, but only for approximately 6% of cases among other persons living in Saskatchewan. The estimated contribution of GDM to the growth in T2DM was highly sensitive to assumptions concerning the post-GDM risk of developing T2DM. CONCLUSIONS GDM may be an important driver for the T2DM epidemic in many subpopulations. Because GDM is a readily identifiable, preventable, and treatable condition, investments in prevention, rapid diagnosis, and evidence-based treatment of GDM in at-risk populations may offer substantial benefit in lowering the T2DM burden over many generations. Model-informed data collection can aid in assessing intervention tradeoffs.

Abstract
BACKGROUND Maternal diabetes mellitus in pregnancy results in greater offspring adiposity at birth. It is unclear whether it is associated with greater adiposity into adulthood, and if so, whether this is via intrauterine mechanisms or shared familial characteristics. METHODS AND RESULTS A record-linkage prospective cohort study of 280,866 singleton-born Swedish men from 248,293 families was used to explore the intrauterine effect of maternal diabetes mellitus on offspring body mass index (BMI) in early adulthood. Maternal diabetes mellitus during pregnancy was associated with greater mean BMI at age 18 in their sons. The difference in BMI was similar within brothers and between nonsiblings. BMI of men whose mothers had diabetes mellitus during their pregnancy was on average 0.94 kg/m² greater (95% confidence interval [CI], 0.35 to 1.52) than in their brothers born before their mother was diagnosed with diabetes, after adjustment for birth year, maternal age, parity and education, birth weight, gestational age, and age at assessment of BMI. Early-pregnancy BMI was positively associated with son's BMI between nonsiblings, but there was no association within brothers. Adjustment of the maternal diabetes-offspring BMI association for maternal BMI did not alter the association either within brothers or between nonsiblings. Results were also robust to sensitivity analyses restricting the within-sibling analyses to siblings born within 3 years of each other. CONCLUSION Maternal diabetes mellitus has long-term consequences for greater BMI in offspring; this association is likely to be via intrauterine mechanisms, and is independent of maternal BMI in early pregnancy.

Abstract
INTRODUCTION Gestational diabetes mellitus (GDM), the most frequent medical complication of pregnancy, is associated with several adverse outcomes over the short- and long-term for both mother and offspring. Standard treatment for GDM consists of insulin injections. Oral hypoglycemic agents (OHAs), on the other hand, are still the subject of controversy. Although OHAs are seemingly as efficient as insulin and may provide better quality of life, congenital malformations and unknown long-term effects are still feared. AREAS COVERED Recent data on the pharmacokinetics of two OHAs (glyburide and metformin) and their clinical use for GDM are reviewed, with a focus on clinical trials and observational studies comparing insulin with glyburide or metformin (1960 - 2010). The review will provide a comprehensive overview of the pros and cons of OHA usage, an appreciation of OHAs' efficiency for the purpose of controlling glycemia and embryogenetic basics relating to congenital malformations. EXPERT OPINION While insulin treatment is an effective therapy for controlling maternal glycemia, it nevertheless requires sufficient education and skills on the part of the patient to manage properly and may cause hypoglycemia, fear and anxiety. Oral treatment as a more user-friendly alternative may thus facilitate the control of GDM in some patients.

Abstract
Discrete fetal androgen excess during early gestation in rhesus monkeys (Macaca mulatta) promotes endocrine antecedents of adult polycystic ovary syndrome (PCOS)-like traits in female offspring. Because developmental changes promoting such PCOS-like metabolic dysfunction remain unclear, the present study examined time-mated, gravid rhesus monkeys with female fetuses, of which nine gravid females received 15 mg of testosterone propionate (TP) subcutaneously daily from 40 to 80 days (first to second trimesters) of gestation [term, mean (range): 165 (155-175) days], whereas an additional six such females received oil vehicle injections over the same time interval. During gestation, ultrasonography quantified fetal growth measures and was used as an adjunct for fetal blood collections. At term, all fetuses were delivered by cesarean section for postnatal studies. Blood samples were collected from dams and infants for glucose, insulin, and total free fatty acid (FFA) determinations. TP injections transiently accelerated maternal weight gain in dams, very modestly increased head diameter of prenatally androgenized (PA) fetuses, and modestly increased weight gain in infancy compared with concurrent controls. Mild to moderate glucose intolerance, with increased area-under-the-curve circulating insulin values, occurred in TP-injected dams during an intravenous glucose tolerance test in the early second trimester. Moreover, reduced circulating FFA levels occurred in PA fetuses during a third trimester intravenous glucagon-tolbutamide challenge (140 days gestation), whereas excessive insulin sensitivity and increased insulin secretion relative to insulin sensitivity occurred in PA infants during an intravenous glucose-tolbutamide test at ∼1.5 mo postnatal age. Data from these studies suggest that experimentally induced fetal androgen excess may result in transient hyperglycemic episodes in the intrauterine environment that are sufficient to induce relative increases in pancreatic function in PA infants, suggesting in this nonhuman primate model that differential programming of insulin action and secretion may precede adult metabolic dysfunction.

Abstract
AIMS We tested the hypothesis that diabetes during pregnancy leads to chromosomal DNA damage and telomere attrition in the feto placental unit and cord blood, and provides evidence for intrauterine programming towards a senescent phenotype in the offspring. METHODS We obtained cord blood from pregnant women with pregestational Type 1 diabetes (n=26), Type 2 diabetes (n=20) or gestational diabetes (n=71), and control subjects without diabetes (n=45, n=76 and n=81, respectively) matched for maternal and gestational age. We measured cord blood mononuclear cell telomere length, telomerase activity (a reverse transcriptase that limits telomere attrition), and concentrations of insulin, high-sensitivity C-reactive protein (hs-CRP) and soluble intercellular adhesion molecule-1 (sICAM-1). RESULTS We found no significant differences between groups in cord blood telomere length in any nucleated cell type, or in hs-CRP or sICAM-1 concentrations, but telomerase activity was higher in cord blood from Type 1 (P<0.05) and gestational diabetes pregnancies (P<0.05), but not in Type 2 diabetes pregnancies. There were no significant relationships between glycaemic control, cord blood telomere length, telomerase activity or inflammatory markers in any group. CONCLUSIONS We found no difference in cord blood telomere length in pregnancies of women with diabetes compared with control subjects, but higher cord blood telomerase activity in Type 1 and gestational diabetes. This may reflect upregulated telomere reverse transcriptase in response to in utero oxidative DNA and telomere damage. These observations are relevant to the hypothesis that diabetes during pregnancy leads to in utero preprogramming towards senescence in the offspring.

Abstract
The Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study of over 23000 diabetes-free pregnancies has shown that at a population level an unequivocal linear relationship exists between maternal glucose concentrations around the beginning of the third trimester of pregnancy and the risk of their baby being born above the ninetieth centile for weight. With the rising incidence of gestational diabetes (GDM) across the developed world, largely paralleling the increased prevalence of obesity, there has been a sharp increase in the risk of pregnancy complications developing related to the birth of macrosomic babies. The associated additional long-term complications of GDM pregnancies means that in the future there is likely to be a large increase in the incidence of type 2 diabetes and associated conditions in both the mothers and their affected offspring. The present review seeks to highlight recent advances and remaining gaps in knowledge about GDM in terms of its genetics (where some of the recently discovered polymorphic risk factors for type 2 diabetes have also proved to be risk factors for GDM) and its treatment by diet, exercise and drugs.

Abstract
Children born to mothers, rather than to fathers, with type 1 diabetes (type 1 DM) or type 2 diabetes (type 2 DM) may have a greater susceptibility to diabetes and obesity in later life, inferring a role for in utero or early post-natal influences on the developing child. This review summarises the studies contributing to this hypothesis, noting some of the controversies including the potential for residual confounding and the influence of maternal BMI. Animal models demonstrate that maternal hyperglycaemia leads to persistent disorders of offspring pancreatic β cell secretory capacity, abnormal insulin signaling in insulin-sensitive tissues and abnormal development of the hypothalamus, associated with aberrant control of energy regulation and obesity in adult life. Prospective studies, particularly follow-up of children born to diabetic mothers participating in RCTs of improved glycemic control are needed to accurately assess the transgenerational influences of maternal diabetes and to evaluate mechanisms inferred from animal data.

Abstract
OBJECTIVE Gestational diabetes mellitus (GDM) is associated with high birth weight in the offspring. This may lead to overweight and insulin resistance during childhood. The aim of the study was to assess the impact of GDM on overweight risk and insulin resistance in offspring. RESEARCH DESIGN AND METHODS BMI measurements were collected at age 2, 8, and 11 years from 232 offspring of mothers with GDM (OGDM) and compared with those from 757 offspring of mothers with type 1 diabetes (OT1D) and 431 offspring of nondiabetic mothers (ONDM) born between 1989 and 2000. Insulin resistance (homeostasis model assessment of insulin resistance [HOMA-IR]) was determined at age 8 and 11 years in 751 children (74 OGDM). Overweight was defined as BMI percentile >or=90; insulin resistance was defined by HOMA-IR. RESULTS Overweight prevalence was increased in OGDM compared with OT1D and to ONDM throughout childhood (age 11 years 31.1, 15.8, and 15.5%; P = 0.005). Maternal obesity was an important predictor of overweight risk in children (age 11 years odds ratio 7.0 [95% CI 1.8-27.7]; P = 0.006); birth size and maternal smoking during pregnancy were inconsistently associated with and treatment of GDM during pregnancy did not affect overweight risk. HOMA-IR was increased in OGDM compared with offspring of ONDM mothers (P = 0.01, adjusted for sex and age) and was associated with the child's BMI (P = 0.004). CONCLUSIONS Overweight and insulin resistance in children is increased in OGDM compared with OT1D or ONDM. The finding that overweight risk is associated mainly with maternal obesity suggests that familial predisposition contributes to childhood growth in these offspring.

Abstract
The impact of gestational diabetes on maternal and fetal health has been increasingly recognized. However, universal consensus on the diagnostic methods and thresholds has long been lacking. Published guidelines from major societies differ considerably from one another, ranging in recommendations from aggressive screening to no routine screening at all. As a result, real-world practice is equally varied. The recently published Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) study, and two randomized controlled trials evaluating treatment of mild maternal hyperglycemia, have served to confirm the findings of smaller, nonrandomized studies solidifying the link between maternal hyperglycemia and adverse perinatal outcomes. In response to these studies, the International Association of Diabetes and Pregnancy Study Groups (IADPSG) has formulated new guidelines for screening and diagnosis of diabetes in pregnancy. Key components of the IADPSG guidelines include the recommendation to screen high-risk women at the first encounter for pre-gestational diabetes, to screen universally at 24-28 weeks' gestation, and to screen with use of the 75-g oral glucose tolerance test interpreting abnormal fasting, 1-h, and 2-h plasma glucose concentrations as individually sufficient for the diagnosis of gestational diabetes. Furthermore, to translate the continuous association between maternal glucose and adverse outcomes demonstrated in the HAPO cohort, they recommend thresholds for positive screening tests at which the odds of elevated birth weight, cord C-peptide, and fetal percent body fat are 1.75 relative to odds of those outcomes at mean glucose values. Opponents to the IADPSG recommendations will likely be those who favor risk-based screening in addition to those who endorse the 50-g glucose challenge test followed by the 100-g oral glucose tolerance test as a more cost-effective, familiar, and possibly, well-validated screening tool. Others may argue that the diagnostic thresholds chosen by the IADPSG are arbitrary and will continue to miss many cases of abnormal glucose metabolism and therefore leave open the possibility of adverse perinatal outcomes due to untreated gestational diabetes. Finally, the potential economic impact of the IADPSG guidelines are unknown, and with minimal long-term data yet available on the offspring of the HAPO cohort, a true cost-effectiveness analysis will be difficult to perform accurately. Given these potential points of contention, the responses of professional and international groups to the IADPSG guidelines are difficult to gauge. Regardless, these guidelines serve to advance the discussion on appropriate screening and diagnosis of diabetes in pregnancy.

Abstract
We investigated whether maternal diabetes programs the offspring to develop hypertension and kidney injury in adulthood and examined potential underlying mechanisms. In a murine model we studied the offspring of three groups of dams (non-diabetic, diabetic, and diabetic treated with insulin). Mean systolic blood pressure in the offspring was monitored from 8 to 20 weeks. Body and kidney weights in the offspring of diabetic mothers were significantly lower than in offspring of non-diabetic mothers. Offspring of diabetic mothers developed hypertension, microalbuminuria, and glucose intolerance. Increased accumulation of extracellular matrix proteins in the glomeruli and marked upregulation of angiotensinogen, angiotensin II type 1 receptor, angiotensin-converting enzyme, transforming growth factor beta-1 (TGF-beta1), and plasminogen activator inhibitor-1 (PAI-1) gene expression were evident in the renal cortex of hypertensive offspring of diabetic mothers. By contrast, angiotensin-converting enzyme-2 (ACE2) gene expression was lower in the hypertensive offspring of diabetic mothers than in that of non-diabetic mothers. These changes were prevented in the offspring of insulin-treated diabetic mothers. These data indicate that maternal diabetes induces perinatal programming of hypertension, renal injury, and glucose intolerance in the offspring and suggest a central role for the activation of the intrarenal renin-angiotensin system and TGF-beta1 gene expression in this process.

Abstract
OBJECTIVE Diabetes during pregnancy is a strong risk factor for obesity in the offspring, but the age at which this association becomes apparent is unknown. The purpose of this study was to examine the relation of glycemia during pregnancy with anthropometry in offspring of nondiabetic pregnant women from the Belfast U.K. center of the multinational Hyperglycemia and Adverse Pregnancy Outcome (HAPO) Study. RESEARCH DESIGN AND METHODS Women from the HAPO Study were invited to participate in follow-up of their offspring aged 2 years. Measurements included height, weight, and thickness of triceps, subscapular, and suprailiac skinfolds. RESULTS A total of 1,165 offspring (73% of eligible children; 598 boys and 567 girls) were seen from ages 22-30 completed months. The only association that reached statistical significance was between categories of maternal 1-h glucose and BMI Z score >or=85th percentile at 2 years (P = 0.017). Overall the correlations between maternal glucose during pregnancy and BMI Z score at age 2 years were weak (fasting glucose r = 0.05, P = 0.08; 1-h glucose r = 0.04, P = 0.22; 2-h glucose r = 0.03, P = 0.36; and area under the curve for glucose r = 0.04, P = 0.18). CONCLUSIONS This study found little association between maternal glucose during pregnancy and obesity in the offspring at this young age. These findings are not unexpected given that study results for young offspring whose mothers had diabetes during pregnancy were indistinguishable from those for normal offspring at this age. It will be interesting to see whether, as these children age, maternal glucose during pregnancy in the ranges included in the HAPO Study will be associated with obesity in their children.

Abstract
Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy. It is defined as diabetes that is first recognized during pregnancy. The diagnosis of GDM is important because it impacts maternal health care during and after pregnancy. The American Diabetes Association, American Congress of Obstetrics and Gynecology, the World Health Organization, and the National Diabetes Data Group all have recommendations for screening; however, there is no consensus. The Hyperglycemia and Adverse Pregnancy Outcome Research Cooperative Study Group published their findings that show hyperglycemia has a significant effect on pregnancy outcome. In addition, recent studies showed that treatment of mild hyperglycemia may affect adverse outcomes. However, at this time no new guidelines for screening and diagnosis of gestational diabetes have been published. This article summarizes the current state of screening for gestational diabetes.

Abstract
OBJECTIVE The goals of this study were to examine the influence of maternal type 1 diabetes during pregnancy on offspring adiposity and glucose tolerance at age 7 years and to assess whether metabolic factors at birth (neonatal leptin and insulin) predict adverse outcomes. RESEARCH DESIGN AND METHODS We examined 100 offspring of mothers with type 1 diabetes (OT1DM) and 45 offspring of control mothers. Mothers had previously been recruited during pregnancy, and, where possible, birth weight, umbilical cord insulin, and leptin were measured. Children were classed as overweight and obese using age-specific reference ranges. RESULTS OT1DM had similar height (control, 1.25 +/- 0. 06 m; OT1DM, 1.24 +/- 0.06 m; P = 0.81) but were heavier (control, 25.5 +/- 3.8 kg; OT1DM, 27.1 +/- 5.7 kg; P = 0.048) and had an increased BMI (control, 16.4 kg/m(2); OT1DM, 17.4 +/- 2.6 kg/m(2), P = 0.005). Waist circumference (control, 56.0 +/- 3.7 cm; OT1DM, 58 +/- 6.8 cm; P = 0.02) and sum of skinfolds were increased (control, 37.5 +/- 17.0 mm [n = 42]; OT1DM, 46.1 +/- 24.2 mm [n = 91]; P = 0.02), and there was a marked increase in the prevalence of overweight and obese children (OT1DM, 22% overweight and 12% obese; control, 0% overweight and 7% obese; chi(2) P = 0.001). Glucose tolerance was not different compared with that in control subjects. BMI at age 7 years correlated with cord leptin (OT1DM, r = 0.25; n = 61, P = 0.047), weakly with adjusted birth weight (r = 0.19; P = 0.06) and hematocrit (r = 0.25; n = 50, P = 0.07), but not cord insulin (OT1DM, r = -0.08; P = 0.54). CONCLUSIONS OT1DM are at increased risk of overweight and obesity in childhood. This risk appears to relate, in part, to fetal leptin and hematocrit but not insulin.

Abstract
AIMS To determine effects on mothers and daughters of gestational diabetes mellitus/gestational impaired glucose tolerance (GDM/GIGT) on their future metabolic and cardiovascular risks. METHODS Case mothers who had GDM/GIGT in pregnancy (cases; n = 90) and normoglycaemic control women (n = 99) and their daughters underwent lifestyle assessment and metabolic tests 15-years post-partum. RESULTS Prevalence of glucose intolerance (GI) in daughters was 1.1%. Maternal prevalence was 44.4% in cases compared to 13.1% in controls, with conversion best predicted by weight gain. Case daughters had higher insulin resistance (IR) and greater waist circumference (WC) (51.2%) relative to control daughters (36.4%, p < 0.05) made worse if case mothers became GI at follow-up (65%) (relative risk =1.8; 95% confidence interval 1.2-2.9). In multivariable linear regression analyses adjusting for daughters' birthweight, maternal obesity (> 30.0 kg/m(2)) at 15years and mothers' case-control status were strong predictors of daughters' WC (p < 0.01; P < 0.01, respectively). For daughters' body mass index (BMI) percentile and percentage of body fat, maternal obesity was a stronger predictor (p < 0.01; p < 0.001)) than mothers' case-control status (p < 0.01; P = 0.09). CONCLUSIONS GDM/GIGT pregnancies led to increased conversion to GI in mothers, minimal in daughters. Case daughters have increased risk of central adiposity and insulin resistance, whereas maternal obesity strongly predicted daughters' BMI percentile and per cent of body fat. Controlling hyperglycaemia in pregnancy and family weight management may provide the key to preventing offspring obesity and glucose intolerance post GDM/GIGT.

Abstract
AIMS/HYPOTHESIS The aim of the study was to examine the association of existing diabetes (i.e. already diagnosed prior to pregnancy), gestational diabetes and glycosuria (both diagnosed and ascertained during pregnancy) with birthweight and future offspring BMI, waist circumference and fat mass (assessed by dual x-ray emission absorptiometry). METHODS A prospective pregnancy/birth cohort study was performed using data from the Avon Longitudinal Study of Parents and Children. RESULTS Among 10,591 mother-offspring pairs included in analyses with birth size, women with existing diabetes (n = 40), those diagnosed with gestational diabetes (n = 53) and those with at least two episodes of ++ glycosuria (n = 372) had greater mean birthweight and odds for macrosomia (birthweight > 4,000 g) than women with none of these. Adjusted odds ratios for macrosomia were 3.56 (95% CI 1.53-8.28), 5.50 (95% CI 1.18-10.30) and 1.58 (95% CI 1.18-2.12) for existing diabetes, gestational diabetes and glycosuria, respectively. Among 6,842 mother-offspring pairs with anthropometric measurements at age 9-11 years, maternal gestational diabetes and glycosuria (but not existing diabetes) were associated with increased offspring odds of general or central overweight/obesity. For gestational diabetes, these associations attenuated towards the null with adjustment for maternal prepregnancy BMI, but independent associations remained for glycosuria. The adjusted odds ratio for general overweight/obesity when comparing women with at least two episodes of ++ glycosuria with those with no evidence of diabetes or glycosuria was 1.35 (95% CI 1.00-1.82) and that for central obesity (top 10% waist circumference vs all others) was 1.31 (95% CI 1.00-1.72). CONCLUSIONS/INTERPRETATION These results provide some evidence for a long-term effect of maternal glycaemia in pregnancy on offspring obesity risk.

Abstract
Low-grade, systemic inflammation is related to increased risk of cardiovascular disease in adults. The proinflammatory state tracks from adolescence to adulthood. Identifying correlates of inflammation in adolescents could provide opportunities to prevent cardiovascular disease in adulthood. However, population-based data on correlates of inflammation in adolescence are limited. Therefore, the authors studied the associations of early-life factors, gender, and lifestyle with inflammation (measured by high-sensitivity C-reactive protein and leukocyte count) at age 16 years (2001-2002) in the prospective, population-based Northern Finland Birth Cohort 1986 Study (n = 5,240). In females, being born small for gestational age and current use of oral contraceptives were associated with the proinflammatory state. The association of birth size with inflammation was not observed in males. In logistic regression analyses, oral contraceptive use (odds ratio (OR) = 2.83), abdominal obesity (OR = 5.17), and smoking (OR = 2.72) were associated with elevation of both inflammation markers in females; abdominal obesity (OR = 5.72) and smoking (OR = 2.02) were associated in males. Thus, females appear more susceptible to the adverse effects of being born small for gestational age than males. Given the widespread use of oral contraceptives and the potential pathophysiologic consequences of the proinflammatory state, the association of oral contraceptive use with inflammation in adolescence may have public health implications.

Abstract
PURPOSE OF REVIEW If the benefits of dietary fibre in healthy adults have extensively been studied, little information is available on the specific needs of pregnant, lactating women or foetus. As far as infants are concerned, milk oligosaccharides are supposed to be the optimal 'dietary fibre'. The supplementation of infant formula with prebiotic oligosaccharides is still discussed. However, recent studies provide a large amount of information, allowing a new discussion on this topic. RECENT FINDINGS Most recent findings are linked to the involvement of dietary fibre in occurrence or prevention of obesity. The multiple mechanisms appear more clearly than earlier. This finding will soon allow appropriate counselling for young mothers at risk of obesity and/or postpartum retention weight, gestational diabetes and preeclampsia. Another area which benefits from recent research is the use of prebiotics in formula. SUMMARY Pregnancy is a critical period during which many physiologic changes occurred and is associated with several gut disorders and metabolic diseases. Dietary fibre may be helpful in the prevention and management of these diseases. Lactation and pregnancy are two phases during which food consumption of the mother can interact with the physiology of the baby. Moreover, the use of formula supplemented in oligosaccharides is able to compensate for the lack of some of the complex molecules naturally present in human milk.

Abstract
The objective of this study was to estimate the national medical costs associated with gestational diabetes mellitus (GDM) in 2007. We analyzed the National Hospital Discharge Survey to estimate the national prevalence of GDM. Using Poisson regression analysis with medical claims for about 27,000 newborns and their mothers, we estimated rate ratios that reflect the increase in use of health care services associated with GDM. Combining GDM prevalence rates with these rate ratios, we calculated etiological fractions that reflect the proportion of national health care resource use associated with GDM. We then multiplied these fractions by estimates of national health care use and costs in 2007. GDM prevalence increases with age, rising from 1.3% of pregnancies of women younger than age 21 to 8.7% of pregnancies of women older than age 35. For the estimated 180,000 GDM pregnancies resulting in delivery, average expenditures increased $3,305 per pregnancy plus $209 in the newborn's first year of life. GDM increased national medical costs by $636 million in 2007-$596 million for maternal costs and $40 million for neonatal costs. Approximately $230 million (36%) of GDM-related medical costs are covered by government programs (primarily Medicaid), $355 million (56%) are covered by private insurers, and $51 million (8%) are covered by self-pay and charity care. GDM imposes a significant economic burden. These estimates of the economic burden of GDM are likely conservative because we focus on near-term medical costs, omitting the increased risk for long-term sequelae.

Abstract
BACKGROUND Clinicians and health professionals are increasingly challenged to understand and consider the different health needs of women and men. The increase of gender awareness and the expanding science of gender medicine will affect more and more clinical practice. This review addresses gender-specific aspects in metabolic disorders and related complications, which represent an increasing burden of this century and a great challenge to public health. DESIGN There is increasing evidence of gender-related differences in risk factors, clinical manifestation and sequelae of obesity and diabetes and increasing knowledge that prevention, detection and therapy of illness affect men and women differently. RESULTS Some gender-specific aspects, especially regarding cardiovascular disease, have been studied in more detail, but for many complications sex-related analyses of the results of both clinical trials and basic science are still missing or disregarded. Impaired glucose and lipid metabolism as well as dysregulation of energy balance and body fat distribution have a great impact on overall health via neuroendocrine changes and inflammatory pathways and deteriorate the course of many diseases with particular harm for women. Metabolic diseases dramatically affect life of men and women from infancy up to old age and are a major challenge for women during pregnancy. Great impact is attached to the intrauterine period and the lifelong implications of fetal programming. CONCLUSIONS Initiation of prospective studies on the impact of gender as primary outcome and investigation of gender-related pathophysiological mechanisms of chronic diseases will help to improve patient care and to implement evidence-based gender-specific prevention programs and clinical recommendations in future.

Abstract
CONTEXT In animal studies, exposure to intrauterine hyperglycemia increases the risk of cardiovascular disease through only partly understood epigenetic mechanisms. Human long-term follow-up studies on the same topic are few. OBJECTIVE The aim was to study the risk of overweight and the metabolic syndrome in adult offspring of women with diet-treated gestational diabetes mellitus (GDM) or type 1 diabetes, and additionally to study associations between estimates of maternal hyperglycemia and outcome in the offspring. DESIGN AND SETTING We conducted a follow-up study of 1066 primarily Caucasian women aged 18-27 yr in the Center for Pregnant Women with Diabetes, Rigshospitalet, Copenhagen, Denmark. PARTICIPANTS Offspring of women with diet-treated GDM (n = 168) and an unexposed reference group (n = 141) participated, as well as offspring of women with type 1 diabetes (n = 160) and offspring from the background population representing an unexposed reference group (n = 128). The follow-up rate was 56% (597 of 1066). MAIN OUTCOME MEASURES Women with body mass index of at least 25 kg/m(2) were considered overweight. The metabolic syndrome was determined by the International Diabetes Federation 2006 criteria. RESULTS The risk of overweight was doubled in offspring of women with diet-treated GDM or type 1 diabetes compared with offspring from the background population, whereas the risk of the metabolic syndrome was 4- and 2.5-fold increased, respectively. Offspring risk of the metabolic syndrome increased significantly with increasing maternal fasting blood glucose as well as 2-h blood glucose (during oral glucose tolerance test). CONCLUSIONS Adult offspring of women with diet-treated GDM or type 1 diabetes are risk groups for overweight and the metabolic syndrome. Intrauterine hyperglycemia may in addition to genetics and other factors contribute to the pathogenesis of overweight and the metabolic syndrome.

Abstract
Pathogenic factors associated with maternal hypercholesterolemia, obesity, and diabetic conditions during pregnancy influence fetal development and predispose offspring to cardiovascular disease. Animal models have established cause–effect relationships consistent with epidemiological findings in humans and have demonstrated, in principle, that interventions before or during pregnancy can reduce or prevent pathogenic in utero programming. However, little is known about the mechanisms by which maternal dysmetabolic conditions enhance disease susceptibility in offspring. Identification of these mechanisms is rendered more difficult by the fact that programming effects in offspring may be latent and may require conventional risk factors and inherited genetic co-factors to become clinically manifest. Given the increasing prevalence of maternal risk factors, which is expected to lead to a wave of cardiovascular disease in the coming decades, and the length of prospective studies on developmental programming in humans, greater-than-usual emphasis on experimental models and translational studies is necessary.

Abstract
Gestational diabetes mellitus is a substantial and growing health concern in many parts of the world. Certain populations are especially vulnerable to developing this condition because of genetic, social, and environmental factors. Gestational diabetes has serious, long-term consequences for both baby and mother, including a predisposition to obesity, metabolic syndrome, and diabetes later in life. Early detection and intervention can greatly improve outcomes for women with this condition and their babies. Unfortunately, screening and diagnostic tests are not uniform worldwide, which could lead not only to underdiagnosis but also undermanagement of the illness. Here, we report the controversies surrounding the causes, screening, diagnosis, management, and prevention of gestational diabetes, and give specific recommendations for research studies to address the major issues of this medical condition.

Abstract
Diabetes in pregnancy has been shown to induce long-term effects in offspring. While considerable attention is focused on the increased incidence of type 2 diabetes mellitus (T2DM) in adult offspring from diabetic mothers, cardiovascular alterations, including hypertension, are also part of lifelong consequences of in-utero exposure to increased glucose concentrations. This review examines the epidemiologic and mechanistic issues involved in the developmental programming of long-term consequences in offspring of diabetic mothers, with a particular emphasis on the renal and vascular mechanisms of hypertension. The factors of increased incidence of T2DM and of obesity in adults born after exposure to diabetes during pregnancy are also discussed, as evidence is accumulating that a vicious circle involving lifelong consequences of diabetes in pregnancy in offspring contributes to the current worldwide epidemic of T2DM.

Abstract
Type 1 diabetes complicates around 1 in 200 to 300 pregnancies in the United Kingdom. Historically maternal type 1 diabetes carried very high risks for mother and child. Introduction of insulin led to an immediate, marked decline in the previously very high rates of maternal mortality; in contrast an improvement in perinatal outcomes occurred more slowly but was nevertheless dramatic. This is strikingly demonstrated by the temporal decline in perinatal mortality in offspring of mothers with type 1 diabetes which was virtually universal before use of insulin in the 1920's, likely remained in excess of 20% even in the 1960's and fell to under 4% by the 1990's. The reasons for this more gradual improvement in perinatal outcomes cannot be defined with precision but will have been influenced by improved glycaemic management with use of intensive, multiple dose insulin treatment and home glucose monitoring; improvements in obstetric and neonatal management, and better management of complications of diabetes before and during pregnancy. In 1989 the St Vincent declaration proposed that pregnancy outcomes in women with type 1 diabetes should approximate those of the non-diabetic population. While the long term improvements in fetal outcomes have been dramatic, contemporary surveys confirm a persistent doubling or more of rates of congenital anomaly and a three to four fold increase in perinatal mortality in the UK and other European countries which will require further clinical innovation to overcome.

Abstract
AIMS/HYPOTHESIS The offspring of mothers with pre-gestational type 1 diabetes (PGDM) may be at increased risk of glucose intolerance and cardiovascular disease in childhood. The underlying causes of these observations, and whether they persist into adulthood, are unknown. The aim of the present study was to test the hypothesis that fetal chromosomal telomere oxidative DNA damage resulting from maternal PGDM programmes the offspring towards a senescent phenotype that is detectable in young adulthood. METHODS We studied 21 young adult offspring (age 16-23 years) with a maternal history of PGDM and 23 age- and weight-matched controls with no maternal history of diabetes. All participants underwent anthropometric assessments, a standard 75 g OGTT, measurement of peripheral blood mononuclear cell and skin fibroblast telomere length, fibroblast senescence, cell DNA damage (by determination of 8-oxoguanine levels using flow cytometry), plasma lipoprotein profiles (determined by nuclear magnetic resonance) and plasma levels of soluble adhesion molecules and inflammatory markers. RESULTS The groups did not differ significantly with respect to anthropometric measures, glucose tolerance, fasting and 2 h plasma insulin levels during OGTT, estimated peripheral insulin resistance, peripheral blood mononuclear cell or fibroblast telomere length, DNA damage or senescence in vitro, plasma NMR lipoprotein profiles or levels of high-sensitivity C-reactive protein. Plasma concentrations of soluble intercellular adhesion molecule 1 (sICAM-1; p < 0.05) and IL-6 (p = 0.08) were higher in the PGDM offspring. CONCLUSIONS/INTERPRETATION Young adult offspring of mothers with PGDM do not differ in terms of glucose tolerance, DNA damage or telomere length from controls of the same weight and BMI. This does not preclude such abnormalities at an earlier age, but there is no evidence of telomere damage as a pre-programming mechanism in the young adults enrolled in this study.

Abstract
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.

Abstract
Diabetes during pregnancy carries important implications for mother and child. Recent evidence has clarified the relationship of maternal glycaemia to neonatal outcomes and demonstrated that appropriate detection and treatment can improve outcomes. This review examines normal physiological changes of glucose metabolism in pregnancy and the association of gestational diabetes with complications both at time of delivery (macrosomia, hypoglycaemia, jaundice, polycythaemia, respiratory distress syndrome, and hypocalcaemia) and later disease associations for both mother and child. Finally recent evidence that at least some of these adverse effects can be reduced is examined. Br J Diabetes Vasc Dis 2009; 9: 27—31

Abstract
BACKGROUND It is well known that children born to mothers with diabetes in pregnancy are more likely to develop metabolic abnormalities in later life. Most prior studies have not differentiated between offspring of mothers with type 1 diabetes (T1DM) and gestational diabetes (GDM) or lack a control group of non-exposed offspring. SUBJECTS Offspring of T1DM (n = 16), GDM (n = 22) and mothers without diabetes (n = 25) born at Oulu University Hospital. AIM To assess insulin secretion and insulin resistance in the offspring of T1DM and GDM at preschool age in comparison with offspring of non-diabetic mothers. METHODS Anthropometric measurements and intravenous glucose tolerance testing were performed. First-phase insulin response (FPIR) and homoeostasis model assessment (HOMA) values were calculated. Pregnancy and birth data were analysed in relation to later metabolic parameters in all three groups using one-way analysis of variance (ANOVA) and analysis of covariance (ANCOVA). RESULTS At a mean age of 4.9 yr, offspring of T1DM had increased fasting serum insulin concentrations (p = 0.044), FPIR (p = 0.034) and HOMA-B values (p = 0.008) compared with offspring of GDM or with offspring of healthy controls (statistically non-significant). The GDM gained least weight during pregnancy, and when adjusted for maternal weight gain during pregnancy, there were no statistically significant differences between study groups. CONCLUSIONS Prenatal exposures to maternal type 1 and gestational diabetes may have different effects on postnatal glucose metabolism in the offspring assessed at a mean age close to 5 yr. Maternal weight gain in pregnancy may affect the postnatal glucose metabolism in the offspring.

Abstract
OBJECTIVE The purpose of this study was to examine age of diabetes diagnosis in youth who have a parent with diabetes by diabetes type and whether the parent's diabetes was diagnosed before or after the youth's birth. RESEARCH DESIGN AND METHODS The cohort comprised SEARCH for Diabetes in Youth Study participants (diabetes diagnosis 2001-2005) with a diabetic parent. SEARCH is a multicenter survey of youth with diabetes diagnosed before age 20 years. RESULTS Youth with type 2 diabetes were more likely to have a parent with either type 1 or type 2 diabetes (mother 39.3%; father 21.2%) than youth with type 1 diabetes (5.3 and 6.7%, respectively, P < 0.001 for each). Type 2 diabetes was diagnosed 1.68 years earlier among those exposed to diabetes in utero (n = 174) than among those whose mothers' diabetes was diagnosed later (P = 0.018, controlled for maternal diagnosis age, paternal diabetes, sex, and race/ethnicity). Age at diagnosis of type 1 diabetes for 269 youth with and without in utero exposure did not differ significantly (difference 0.96 year, P = 0.403 after adjustment). Controlled for the father's age of diagnosis, father's diabetes before the child's birth was not associated with age at diagnosis (P = 0.078 for type 1 diabetes; P = 0.140 for type 2 diabetes). CONCLUSIONS Type 2 diabetes was diagnosed at younger ages among those exposed to hyperglycemia in utero. Among youth with type 1 diabetes, the effect of the intrauterine exposure was not significant when controlled for mother's age of diagnosis. This study helps explain why other studies have found higher age-specific rates of type 2 diabetes among offspring of women with diabetes.
