Abstract
Evidence is emerging on the role of maternal diet, gut microbiota, and other lifestyle factors in establishing lifelong health and disease, which are determined by transgenerationally inherited epigenetic modifications. Understanding epigenetic mechanisms may help identify novel biomarkers for gestation-related exposure, burden, or disease risk. Such biomarkers are essential for developing tools for the early detection of risk factors and exposure levels. It is necessary to establish an exposure threshold due to nutrient deficiencies or other environmental factors that can result in clinically relevant epigenetic alterations that modulate disease risks in the fetus. This narrative review summarizes the latest updates on the roles of maternal nutrients (n-3 fatty acids, polyphenols, vitamins) and gut microbiota on the placental epigenome and its impacts on fetal brain development. This review unravels the potential roles of the functional epigenome for targeted intervention to ensure optimal fetal brain development and its performance in later life.

Abstract
Obesity is a global health problem and is increasing in prevalence in most countries. Although obesity affects all age groups, children are the most vulnerable sector. Functional foods are novel formulated foods containing substances (i.e., nutrients, phytochemicals, probiotics, etc.) that have potential health-enhancing or disease-preventing value. The research objective was to study the possible beneficial effects of providing a functional food made with amaranth flour, chia seed, and curcumin extract on the metabolism and behavior of a rat model of childhood obesity. Male Wistar rat pups from two litters of different sizes, a normal litter (NL) (10 pups) and a small litter (SL) (4 pups), were used. After weaning, the rats were fed a hypercaloric diet (HD) or an HD supplemented with the functional food mixture. Body weight and energy intake were measured for seven weeks, and locomotor activity, learning, and memory tests were also performed. At the end of the experiment, glucose and lipid metabolism parameters were determined. The results showed that in this model of obesity produced by early overfeeding and the consumption of a hypercaloric diet, anxiety-like behaviors and metabolic alterations occurred in the rat offspring; however, the provision of the functional food failed to reduce or prevent these alterations, and an exacerbation was even observed in some metabolic indicators. Interestingly, in the NL rats, the provision of the functional food produced some of the expected improvements in health, such as significant decreases in body weight gain and liver cholesterol and non-significant decreases in adipose tissue and leptin and insulin serum levels.

Abstract
The prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD) is significant, impacting almost one-third of the global population. MAFLD constitutes a primary cause of end-stage liver disease, liver cancer and the need for liver transplantation. Moreover, it has a strong association with increased mortality rates due to various extrahepatic complications, notably cardiometabolic diseases. While MAFLD is typically correlated with obesity, not all individuals with obesity develop the disease and a significant percentage of MAFLD occurs in patients without obesity, termed lean MAFLD. The clinical features, progression and underlying physiological mechanisms of patients with lean MAFLD remain inadequately characterized. The present review aims to provide a comprehensive summary of current knowledge on lean MAFLD and offer a perspective on defining MAFLD in individuals with normal weight. Key to this process is the concept of metabolic health and flexibility, which links states of dysmetabolism to the development of lean MAFLD. This perspective offers a more nuanced understanding of MAFLD and its underlying mechanisms and highlights the importance of considering the broader metabolic context in which the disease occurs. It also bridges the knowledge gap and offers insights that can inform clinical practice.

Dietary Intake Patterns and Lifestyle Behaviors of Pregnant Women Living in a Manitoba First Nations Community: Implications for Fetal Alcohol Spectrum Disorder. Nutrients 2022; 14:nu14153233. [PMID: 35956409 PMCID: PMC9370556 DOI: 10.3390/nu14153233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 07/21/2022] [Accepted: 08/05/2022] [Indexed: 11/17/2022] Open
Abstract
The information on the nutrition status of women at-risk of carrying a child with fetal alcohol spectrum disorder (FASD) is scarce, particularly in the First Nations population living on reserve. This study examined and compared nutrition status, dietary intake, and lifestyle patterns of pregnant at-risk, defined as those who consume alcoholic drink during the current pregnancy, and non-at-risk women living in northern Manitoban community. Thirty-seven pregnant, First Nations women (at-risk n = 15; non-at-risk, n = 22) were recruited to participate in the study. A questionnaire, presented in paper and iPad formats, collected information on participants’ demographics, dietary intake, lifestyle, pregnancy outcomes, and maternal health. A food frequency questionnaire and 24-h recall were used to determine nutrient intake. Nutrient values were assessed using Dietary Reference Intakes (DRI). At-risk and non-at-risk women were below the Canada Food Guide serving size recommended for Vegetable and Fruit, Grain, and Milk Products with 93%, 92%, and 93% of participants not meeting the recommendations, respectively. Women met the recommendations for vitamins A, B1, B12, C, niacin, choline, as well as calcium, and zinc. Sixty eight percentage (%) of participants did not meet the recommendations for folate and iron, and 97% for docosahexaenoic acid (DHA). Significant differences were observed between non-at-risk and at-risk women for mean % DRI intakes of vitamin C (313 ± 224 vs. 172 ± 81 mg/day), niacin (281 ± 123 vs. 198 ± 80 mg/day), folate (70 ± 38 vs. 10 ± 22 mcg/day), and iron (101 ± 74 vs. 74 ± 30 mg/day). The findings of this study lay a fundamental premise for the development of community nutrition programs, nutrition education, and nutrition intervention, such as community specific prenatal supplementation. These will assist in ensuring adequate maternal nutrient intake and benefit families and communities in Northern Manitoba with and without alcohol insult.

Abstract
BACKGROUND Maternal undernutrition has been associated with psychiatric and neurological disorders characterized by learning and memory impairment. OBJECTIVE Considering the lack of evidence, we aimed to analyze the effects of gestational protein restriction on learning and memory function associated with hippocampal cell numbers and neurodegenerative protein content later in life. METHODS Experiments were conducted in gestational low- (LP, 6% casein) or regular-protein (NP, 17% casein) diet intake offspring. Behavioral tests, isolated hippocampal isotropic fractionator cell studies, immunoblotting, and survival lifetime were observed. RESULTS The birthweight of LP males is significantly reduced relative to NP male progeny, and hippocampal mass increased in 88-week-old LP compared to age-matched NP offspring. The results showed an increased proximity measure in 87-week-old LP compared to NP offspring. Also, LP rats exhibited anxiety-like behaviors compared to NP rats at 48 and 86-wk of life. The estimated neuron number was unaltered in LP rats; however, non-neuron cell numbers increased compared to NP progeny. Here, we showed unprecedented hippocampal deposition of brain-derived neurotrophic factor, amyloid-β peptide (Aβ), and tau protein in 88-week-old LP relative to age-matched NP offspring. CONCLUSION To date, no predicted studies showed changes in hippocampal morphological structure in maternal protein-restricted elderly offspring. The current data suggest that gestational protein restriction may accelerate hippocampal function loss, impacting learning/memory performance, and supposedly developing diseases similar to Alzheimer's disease (AD) in elderly offspring. Thus, we propose that maternal protein restriction could be an elegant and novel method for constructing an AD-like model in adult male offspring.

Abstract
The Barker hypothesis strongly supported the influence of fetal environment on the development of chronic diseases in later life. Multiple experimental and human studies have identified that the deleterious effect of fetal programming commonly leads to alterations in renal development. The interplay between environmental insults and fetal genome can induce epigenetic changes and lead to alterations in the expression of renal phenotype. In this review, we have explored the renal development and its functions, while focusing on the epigenetic findings and functional aspects of the renin-angiotensin system and its components.

A Meta-Analysis of the Association Between Breastfeeding and Early Childhood Obesity. J Pediatr Nurs 2020; 53:57-66.

Abstract
PROBLEM Several studies have indicated a protective effect of breastfeeding on reducing the risk of childhood obesity, however, this remains controversial. The aim of this meta-analysis is to clarify the association between breastfeeding and the risk of preschoolers' obesity. ELIGIBILITY CRITERIA Prospective cohort studies published prior to December 1, 2019 were systematically searched in PubMed, EMBASE, the Web of Science and the Cochrane Library databases. Meta-analysis was performed using Stata 15.1. SAMPLE Twenty-six publications involving 332,297 participants were eligible for inclusion. RESULTS The pooled odds ratio (OR) of the risk of obesity in ever-breastfed preschoolers was 0.83 (95%CI [0.73,0.94]) compared with their never-breastfed counterparts. Random-effects dose-response model revealed a negative correlation between the duration of breastfeeding and risk of obesity (regression coefficient = -0.032, p = .001). Categorical analysis confirmed this dose-response association (1 day to <3 months of breastfeeding: OR = 1.07, 95%CI [0.94,1.21]; 3 months to <6 months: OR = 0.96, 95%CI [0.60,1.54]; ≥6 months: OR = 0.67, 95%CI [0.58,0.77]). One month of breastfeeding was associated with a 4.0% decrease in risk of obesity (OR = 0.96/month of breastfeeding, 95% CI [0.95, 0.97]). Under the reference of never breastfeeding, the summary OR of exclusive breastfeeding was 0.53 (95%CI [0.45,0.63]). CONCLUSIONS Breastfeeding is inversely associated with a risk of early obesity in children aged two to six years. Moreover, there is a dose-response effect between duration of breastfeeding and reduced risk of early childhood obesity. IMPLICATIONS Clinical nurses' guidance and advice that prolong the duration of breastfeeding and promote exclusive breastfeeding are needed to prevent the development of later childhood obesity.

Abstract
PURPOSE The study aimed to investigate the effect of breastfeeding, formula feeding and mix feeding (breastfed plus formula-fed) on the expression level of obesity-predisposing genes including fat mass and obesity-associated (FTO), carnitine palmitoyltransferase 1A (CPT1A), and peroxisome proliferator-activated receptor-α (PPAR-α) in 5- to 6-month-old infants. PATIENTS AND METHODS A total of 150 infants participated in this case-control study. All subjects were healthy infants aged 5-6 months that divided into 3 groups: breastfed, formula-fed, and mix-fed. The expression level of FTO, CPT1A, and PPAR-α genes in peripheral blood mononuclear cells (PBMC) was evaluated in each group using reverse transcription-polymerase chain reaction (RT-PCR) method. RESULTS Our findings showed that the current weight, height, and head circumference of infants in the formula feeding and mix feeding groups were significantly higher than those in the exclusive breastfeeding group. The expression level of FTO and CPT1A genes in formula-fed and mix-fed infants was significantly higher (p<0.001) than that in breastfed infants, while the expression level of PPAR-α gene was significantly lower (p<0.05). CONCLUSION Breastfeeding showed modulatory effects on the expression level of obesity-predisposing genes and can protect against obesity and subsequent non-communicable diseases. However, more investigations are required to explain the epigenetic effects of breast milk.

Abstract
BACKGROUND Intrauterine exposure to gestational diabetes (GDM) is associated with increased adiposity; however, not all offspring exposed to GDM exhibit excess adiposity. OBJECTIVES Examine whether optimal diet and activity behaviours in infancy, childhood, and adolescence modify the association between GDM exposure and adiposity. METHODS In 564 offspring (84 exposed to GDM), we assessed breastfeeding (maternal recall), dietary intake (food frequency questionnaire), physical activity (3-day recall), and adiposity (BMI, waist-to-height ratio, visceral and subcutaneous adipose tissue, and subscapular-to-triceps skinfold ratio) at 10.4 (SD, 1.5) and 16.7 (SD, 1.2) years. Optimal behaviours were defined as >6 breastmilk months, Healthy Eating Index score >60, and daily vigorous activity >1 hour. Linear mixed models assessed the association between GDM exposure and adiposity among those with optimal versus suboptimal health behaviours, adjusting for sex, race/ethnicity, age, and pubertal status. RESULTS GDM exposure was associated with increased skinfold ratio, visceral and subcutaneous adipose tissue among those with <6 breastmilk months (all Ps < .05), but only associated with increased skinfold ratio among those with >6 breastmilk months (P = .01). GDM exposure was associated with increases in all adiposity measures among those with Healthy Eating Index scores <60 (P < .01), but not those with scores >60 (P > .10). GDM exposure was associated with increased BMI and subcutaneous adipose tissue among those with >1 hour of vigorous activity (P < .05) but not among those with <1 hour of vigorous activity (P > .30). CONCLUSIONS The association of GDM exposure with excess adiposity is attenuated in offspring with more optimal diet and activity behaviours in infancy, childhood, and adolescence.

Abstract
Maternal high-fat diet (HFD) overfeeding pre- and during pregnancy and lactation may 'program' a 'diabesity' predisposition in the offspring, for inconclusive reasons. Acquired alterations of the hypothalamic promoter methylation and mRNA expression of the satiety neurohormone Pomc are possibly of critical importance here. We investigated within one developmental approach, including male and female rats, the sex-specific DNA methylation pattern and corresponding mRNA expression of both Pomc and its endogenous functional antagonist Agrp in the hypothalamus of adult HFD offspring. Obesity and diabetic disturbances occurred in both male and female HFD offspring, accompanied by altered Pomc promoter methylation pattern. However, this was not related to significant Pomc mRNA expression alterations. In contrast, male-specific alterations of Agrp promoter methylation were found, even associated with reduced mRNA expression of this orexigenic/anabolic Pomc antagonist. In conclusion, acquired epigenetic alterations of the hypothalamic Agrp-Pomc system hardly explain the 'diabesity' phenotype in HFD offspring, while distinct vulnerability and functionality of Agrp promoter and related genomic regions methylation should be further investigated.

Abstract
The global incidence of diabetes mellitus, including diabetes in pregnant women, is on the rise. Diabetes mellitus in a pregnant woman jeopardizes not only maternal health but can also have significant implications on the child to be born. Therefore, timely diagnosis and strict glycemic control are of utmost importance in achieving a safe outcome for both the mother and fetus. The treating physician should be aware of the complications that can arise due to poor glycemic control during pregnancy. The objective of this article is to discuss the key concerns in a neonate born to diabetic mother, the underlying pathogenesis, and the screening schedule during pregnancy.

Abstract
Animal evidence has suggested that maternal emotional and nutritional stress during pregnancy is associated with behavioral outcomes in offspring. The nature of the stresses applied may differ, but it is often assumed that the mother's hippocampus-hypothalamic-pituitary-adrenal (HHPA) axis response releases higher levels of glucocorticoid hormones. The bed nucleus of the stria terminalis (BNST) is in a pivotal position to regulate the HHPA axis and the stress response, and it has been implicated in anxiety behavior. In the current study, to search whether BNST structural changes and neurochemical alterations are associated with anxiety-related behavior in adult gestational protein-restricted offspring relative to an age-matched normal protein diet (NP) rats, we conduct behavioral tests and, BNST dendritic tree analysis by Sholl analysis, associated to immunoblotting-protein quantification [11β-HSD2, GR, MR, AT1R, 5HT1A and 5HT2A, corticotrophin-releasing factor (CRH) and CRH1]. Dams were maintained either on isocaloric standard rodent chow [with NP content, 17% casein or low protein content (LP), 6% casein] chow throughout their entire pregnancy. Here, in rats subjected to gestational protein restriction, we found: (a) a significant reduction in dendritic length and impoverished dendritic arborization in BNST neurons; (b) an elevated plasmatic corticosterone levels; and (c) associated with enhanced anxiety-like behavior when compared with age-matched NP offspring. Moreover, altered protein (11β-HSD2, GR, MR and type 1 CRH receptors) expressions may underlie the increase in anxiety-like behavior in LP offspring. This work represents the first demonstration that BNST developmental plasticity by maternal protein restriction, resulting in fine structural changes and neurochemical alterations that are associated with modified behavioral states.

Abstract
BACKGROUND The rising prevalence of childhood obesity in Asia has led to interest in potential risk factors such as infant health-related quality of life (HRQoL), temperament and eating behaviors. This pilot study evaluated the utility of administering parent-reported outcome measures (PROMs) to explore these factors in Filipino infants and examined the relationships between these factors and infant sex, formula intake and weight, over time. METHODS Forty healthy, 4-week-old, formula-fed infants (n = 20 males) were enrolled in this 6-week, prospective, uncontrolled study during which infants were exclusively fed a standard term infant formula enriched with alpha-lactalbumin. On Day-1 and 42, anthropometrics were measured and mothers completed a 97-item measure of HRQoL [Infant Toddler Quality of Life Questionnaire (ITQOL)] covering 6 infant-focused and 3 parent-focused concepts and a 24-item measure of infant temperament [Infant Characteristics Questionnaire (ICQ)]. At Day-42, mothers also completed an 18-item measure of infant appetite [Baby Eating Behaviour Questionnaire (BEBQ)]. A 3-day formula intake diary was completed before Day-42. Nonparametric statistics were used to evaluate correlations among outcomes and compare outcomes by visit and sex. RESULTS Thirty-nine infants completed the study; similar results were observed in males and females. Completion of PROMs was 100% with no missing responses, but Cronbach's α was low for many concept scales scores. ITQOL scores [range 0 (worst)-100 (best)] were generally high (median ≥ 80) except for Day-1 and Day-42 Temperament and Mood and Day-1 General Health Perceptions scores. ITQOL but not ICQ temperament scores improved significantly between Day-1 and Day-42 (P < 0.01). Mean ± standard deviation BEBQ scores (range 1-5) were high for Enjoyment of Food (4.59 ± 0.60) and Food Responsiveness (3.53 ± 0.81), and low for Satiety Responsiveness (2.50 ± 0.73) and Slowness in Eating (1.71 ± 0.60). Better HRQoL scores were significantly (P < 0.05) associated with high General Appetite scores (3 ITQOL concepts, r = 0.32 to 0.54), greater Enjoyment of Food (4 ITQOL concepts, r = 0.35 to 0.42) and low levels of Slowness in Eating (7 ITQOL concepts, r = - 0.32 to - 0.47). CONCLUSION Findings demonstrated the utility of the ITQOL, ICQ and BEBQ for measuring HRQoL, temperament and eating behavior, and the need for further adaptations for use in Filipino infants.

Abstract
Prenatal exposure to maternal hyperglycemia is associated with an increased risk of later adverse metabolic health. Changes in the regulation of peroxisome proliferator-activated receptor-γ coactivator-1α (PPARGC1A) in skeletal muscle and subcutaneous adipose tissue (SAT) is suggested to play a role in the developmental programming of dysmetabolism based on studies of human subjects exposed to an abnormal intrauterine environment (e.g., individuals with a low birth weight). We studied 206 adult offspring of women with gestational diabetes mellitus (O-GDM) or type 1 diabetes (O-T1D) and of women from the background population (O-BP) using a clinical examination, oral glucose tolerance test, and gene expression and DNA methylation of PPARGC1A in skeletal muscle and SAT. Plasma glucose was significantly higher for both O-GDM and O-T1D compared with O-BP (P < 0.05). PPARGC1A gene expression in muscle was lower in O-GDM compared with O-BP (P = 0.0003), whereas no differences were found between O-T1D and O-BP in either tissue. PPARGC1A DNA methylation percentages in muscle and SAT were similar among all groups. Decreased PPARGC1A gene expression in muscle has previously been associated with abnormal insulin function and may thus contribute to the increased risk of metabolic disease in O-GDM. The unaltered PPARGC1A gene expression in muscle of O-T1D suggests that factors other than intrauterine hyperglycemia may contribute to the decreased PPARGC1A expression in O-GDM.

Abstract
BACKGROUND Events during foetal or early extrauterine life may affect bodily structure and/or functions and even pave the way for adult diseases. AIMS To find whether extremely low birth weight (ELBW) infants differ from healthy controls regarding the excretion of steroid metabolites. METHODS The study compared 17 female and 10 male ELBW infants, all prepubertal, aged 8-11 years, birth weight <1,000 g, with 27 age- and sex-matched controls. All were healthy at the time of the study. Height, weight and BMI did not differ between the groups. Results were adjusted according to body surface area. 36 urinary steroid metabolites were quantified by gas chromatography-mass spectrometry. RESULTS In the ELBW girls 33/36 steroid metabolites were higher (19 significantly) than in the controls. All 36 steroid metabolites were higher in the ELBW boys (9 significantly) than in the controls. Sums of mineralocorticoid precursors, metabolites descriptive for cortisol and parameters of adrenal androgen production were significantly higher in ELBW infants (both sexes). Only the sum of the metabolites known to be illustrative for adrenal 11β-hydroxysteroid dehydrogenase activity was not different. CONCLUSION Prepubertal ELBW children have an augmented urinary excretion of adrenal androgens, cortisol and mineralocorticoid precursors. These findings corroborate and help to explain the link between early-life adversity and subsequent adrenocortical function.

Abstract
BACKGROUND The prevalence of overweight infants and toddlers has increased by 60% in the past 30 years and is a significant contributor to diabetes, cardiovascular disease, and early morbidity and mortality. The World Health Organization's updated meta-analysis in 2013 observed an association between breastfeeding and a lower prevalence of obesity later in life. The purpose of this study was to assess the growth of children in a cohort of Australian twins to examine associations between duration of breastfeeding and growth at 18 months of age. Our hypothesis is that the anthropometric measurements of the participants will be greater with shorter duration of breastfeeding. METHODS Methods include using cross-sectional data from a cohort at the 18-month visit (n = 179) in the Peri/postnatal Epigenetics Twins Study (PETS) to assess the relationship between duration of breastfeeding and infant size at 18 months of age. Inclusion criteria were birth weight of more than 2000 grams and breastfed for less than 1 month, 1 to 3 months, or 4 to 6 months. RESULTS The analysis suggested that infants breastfed for 1 to 3 months were significantly larger than infants breastfed for 4 to 6 months in terms of mean body mass index (BMI) (0.61 kg/m(2); P = .02; 95% confidence interval [CI], 0.17-1.05), arm circumference (0.66 cm; P = .006; 95% CI, 0.26-1.06), and abdominal circumference (1.16 cm; P = .03; 95% CI, 0.26-2.06). The analysis also suggested that infants breastfed for less than 1 month were significantly larger than infants breastfed for 4 to 6 months in terms of mean arm circumference (0.72 cm; P = .009; 95% CI, 0.26-1.17). CONCLUSION Results suggest that supplementing with non-breast milk before 4 months of age was associated with an increased BMI, arm circumference, and abdominal circumference at 18 months of age. The mean BMI decreased from 85% to 65% when infants were breastfeeding for 4 to 6 months as compared to breastfeeding for 1 to 3 months. Breastfeeding for 4 to 6 months appeared to protect against the risk of obesity for the children in the PETS.

Abstract
The present study had 2 objectives, first, to investigate possible relationships between increased gestational weight gain and demographic, clinical, paraclinical, genetic, and bioimpedance (BIA) characteristics of Romanian mothers, and second, to identify the influence of predictors (maternal and newborns characteristics) on our outcome birth weight (BW).We performed a cross-sectional study on 309 mothers and 309 newborns from Romania, divided into 2 groups: Group I-141 mothers with high gestational weight gain (GWG) and Group II-168 mothers with normal GWG, that is, control group.The groups were evaluated regarding demographic, anthropometric (body mass index [BMI], middle upper arm circumference, tricipital skinfold thickness, weight, height [H]), clinical, paraclinical, genetic (interleukin 6 [IL-6]: IL-6 -174G>C and IL-6 -572C>G gene polymorphisms), and BIA parameters.We noticed that fat mass (FM), muscle mass (MM), bone mass (BM), total body water (TBW), basal metabolism rate (BMR) and metabolic age (P < 0.001), anthropometric parameters (middle upper arm circumference, tricipital skinfold thickness; P < 0.001/P = 0.001) and hypertension (odds ratio = 4.65, 95% confidence interval: 1.27-17.03) were higher in mothers with high GWG. BW was positively correlated with mothers' FM (P < 0.001), TBW (P = 0.001), BMR (P = 0.02), while smoking was negatively correlated with BW (P = 0.04). Variant genotype (GG+GC) of the IL-6 -572C>G polymorphism was higher in the control group (P = 0.042).We observed that high GWG may be an important predictor factor for the afterward BW, being positively correlated with FM, TBW, BMR, metabolic age of the mothers, and negatively with the mother's smoking status. Variant genotype (GG+GC) of the IL-6 -572C>G gene polymorphism is a protector factor against obesity in mothers. All the variables considered explained 14.50% of the outcome variance.

Abstract
Maternal nutrition during pregnancy and lactation influences the offspring's health in the long-term. Indeed, human epidemiological studies and animal model experiments suggest that either an excess or a deficit in maternal nutrition influence offspring development and susceptibility to metabolic disorders. Different epigenetic mechanisms may explain in part the way by which dietary factors in early critical developmental steps might be able to affect the susceptibility to develop metabolic diseases in adulthood. microRNAs are versatile regulators of gene expression and play a major role during tissue homeostasis and disease. Dietary factors have also been shown to modify microRNA expression. However, the role of microRNAs in fetal programming remains largely unstudied. This review evaluates in vivo studies conducted to analyze the effect of maternal diet on the modulation of the microRNA expression in the offspring and their influence to develop metabolic and cardiovascular disease in later life. In overall, the available evidence suggests that nutritional status during pregnancy influence offspring susceptibility to the development of cardiometabolic risk factors, partly through microRNA action. Thus, therapeutic modulation of microRNAs can open up new strategies to combat - later in life - the effects of nutritional insult during critical points of development.

Abstract
Obesity causes white adipose tissue (WAT) inflammation and insulin resistance in some, but not all individuals. Here, we used a mouse model of early postnatal overfeeding to determine the role of neonatal nutrition in lifelong WAT inflammation and metabolic dysfunction. C57BL/6J mice were reared in small litters of 3 (SL) or normal litters of 7 pups (NL) and fed either regular chow or a 60% high fat diet (HFD) from 5 to 17 weeks. At weaning, SL mice did not develop WAT inflammation despite increased fat mass, although there was an up-regulation of WAT Arg1 and Tlr4 expression. On HFD, adult SL mice had greater inguinal fat mass compared to NL mice, however both groups showed similar increases in visceral fat depots and adipocyte hypertrophy. Despite the similar levels of visceral adiposity, SL-HFD mice displayed greater impairments in glucose homeostasis and more pronounced hepatic steatosis compared to NL-HFD mice. In addition, WAT from SL mice fed a HFD displayed greater crown-like structure formation, increased M1 macrophages, and higher cytokine gene expression. Together, these data suggest that early postnatal overnutrition may be a critical determinant of fatty liver and insulin resistance in obese adults by programming the inflammatory capacity of adipose tissue.

Abstract
Extensive experimental animal studies and epidemiological observations have shown that environmental influences during early development affect the risk of later pathophysiological processes associated with chronic, especially noncommunicable, disease (NCD). This field is recognized as the developmental origins of health and disease (DOHaD). We discuss the extent to which DOHaD represents the result of the physiological processes of developmental plasticity, which may have potential adverse consequences in terms of NCD risk later, or whether it is the manifestation of pathophysiological processes acting in early life but only becoming apparent as disease later. We argue that the evidence suggests the former, through the operation of conditioning processes induced across the normal range of developmental environments, and we summarize current knowledge of the physiological processes involved. The adaptive pathway to later risk accords with current concepts in evolutionary developmental biology, especially those concerning parental effects. Outside the normal range, effects on development can result in nonadaptive processes, and we review their underlying mechanisms and consequences. New concepts concerning the underlying epigenetic and other mechanisms involved in both disruptive and nondisruptive pathways to disease are reviewed, including the evidence for transgenerational passage of risk from both maternal and paternal lines. These concepts have wider implications for understanding the causes and possible prevention of NCDs such as type 2 diabetes and cardiovascular disease, for broader social policy and for the increasing attention paid in public health to the lifecourse approach to NCD prevention.

Abstract
AIMS The cardiovascular risk factor profile of a child as well as the development of body weight are influenced by genetic and childhood factors. Circulating insulin concentrations reflect the metabolic cardiovascular risk and may trigger weight gain. We aimed at identifying parental and childhood factors which may influence fasting plasma insulin concentrations in children. METHODS The Ulm Birth Cohort study (UBCS) is a prospective birth cohort study. At baseline, birth characteristics, maternal pre-pregnancy body mass index (BMI) values as well as parental socioeconomic parameters were obtained. At the 8-yr follow-up examination, weights, heights, and fasting plasma insulin concentrations in n = 422 children and their parents were measured. Offspring of women with gestational diabetes mellitus were excluded from statistical analysis. RESULTS Fasting plasma insulin concentrations of children were significantly correlated with maternal pre-pregnancy BMI values (r = 0.16) as well as with maternal (r = 0.26) but not with paternal fasting plasma insulin concentrations (r = 0.11) at the 8-yr follow-up examination. The risk for high fasting plasma insulin concentrations (≥75th internal percentile) was 2.30 (1.34-3.92) in children who also had high plasma insulin concentrations in umbilical cord blood compared to children having lower plasma insulin concentrations (<75th internal percentile) in umbilical cord blood. In addition, we observed that children with high fasting plasma insulin concentrations at the age of 8 had an altered BMI trajectory in childhood, characterized by higher BMI values from the age of 1 onwards, compared to children with lower insulin concentrations. CONCLUSION Our observations support the hypothesis of perinatal programming of offspring insulin concentrations and BMI values by maternal pre-pregnancy BMI values.

Abstract
Overweight and obesity before conception as well as excessive weight gain during pregnancy are associated with endocrinological changes of mother and fetus. Insulin resistance physiologically increases during pregnancy, additional obesity further increases insulin resistance. In combination with reduced insulin secretion this leads to gestational diabetes which may develop into type-2-diabetes. The adipose tissue produces TNF-alpha, interleukins and leptin and upregulates these adipokines. Insulin resistance and obesity induce inflammatory processes and vascular dysfunction, which explains the increased rate of pregnancy-related hypertension and pre-eclampsia in obese pregnant women. Between 14 and 28 gestational weeks, the fetal adipose tissue is generated and the number of fat lobules is determined. Thereafter, an increase in adipose tissue is arranged by an enlargement of the lobules (hypertrophy), or even an increase in the number of fat cells (hyperplasia). Human and animal studies have shown that maternal obesity "programmes" the offspring for further obesity and chronic disease. Pregnant women, midwives, physicians and health care politicians should be better informed about prevention, pathophysiological mechanisms, and the burden for society caused by obesity before, during and after pregnancy.

Abstract
Hormonal imprinting is an epigenetic process which is taking place perinatally at the first encounter between the developing hormone receptors and their target hormones. The hormonal imprinting influences the binding capacity of receptors, the hormone synthesis of the cells, and other hormonally regulated functions, as sexual behavior, aggressivity, empathy, etc. However, during the critical period, when the window for imprinting is open, molecules similar to the physiological imprinters as synthetic hormone analogs, other members of the hormone families, environmental pollutants, etc. can cause faulty imprinting with life-long consequences. The developing immune system, the cells of which also have receptors for hormones, is very sensitive to faulty imprinting, which causes alterations in the antibody and cytokine production, in the ratio of immune cells, in the defense against bacterial and viral infections as well as against malignant tumors. Immune cells (lymphocytes, monocytes, granulocytes and mast cells) are also producing hormones which are secreted into the blood circulation as well as are transported locally (packed transport). This process is also disturbed by faulty imprinting. As immune cells are differentiating during the whole life, faulty imprinting could develop any time, however, the most decisive is the perinatal imprinting. The faulty imprinting is inherited to the progenies in general and especially in the case of immune system. In our modern world the number and amount of artificial imprinters (e.g. endocrine disruptors and drugs) are enormously increasing. The effects of the faulty imprinters most dangerous to the immune system are shown in the paper. The present and future consequences of the flood of faulty imprintings are unpredictable however, it is discussed.

Abstract
Studies have demonstrated that nutrient deficiency during pregnancy or in early postnatal life results in structural abnormalities in the offspring hippocampus and in cognitive impairment. In an attempt to analyze whether gestational protein restriction might induce learning and memory impairments associated with structural changes in the hippocampus, we carried out a detailed morphometric analysis of the hippocampus of male adult rats together with the behavioral characterization of these animals in the Morris water maze (MWM). Our results demonstrate that gestational protein restriction leads to a decrease in total basal dendritic length and in the number of intersections of CA3 pyramidal neurons whereas the cytoarchitecture of CA1 and dentate gyrus remained unchanged. Despite presenting significant structural rearrangements, we did not observe impairments in the MWM test. Considering the clear dissociation between the behavioral profile and the hippocampus neuronal changes, the functional significance of dendritic remodeling in fetal processing remains undisclosed.

Abstract
Breast feeding is the best way to nurture healthy newborns of healthy mothers. A number of studies have shown that breast feeding may protect against the later development of obesity and related metabolic diseases. Using data from our own meta-analysis as well as studies by other groups, in this review we systematically examine the current state of evidence regarding this topic. Breast feeding, in general, is shown to be associated later in a child's life with decreased risk of overweight, decreased blood cholesterol and blood pressure, and a reduced risk of developing type 2 diabetes. Additionally, we review data of our Kaulsdorf Cohort Study (KCS) showing, however, that these effects might be reversed when the mother is affected by a non-communicable disease such as diabetes mellitus, which alters the composition of breast milk. In particular, exposure to breast milk from diabetic mothers during the first days of life (first week; early neonatal period) seems to increase rather than decrease risk of overweight and, consecutively, impaired glucose tolerance in childhood. Taken together, current findings show clearly that breast feeding is effective in lowering the risk of developing key features of the metabolic syndrome in later life, and should therefore be promoted. With increasing prevalence of overweight and diabetes in women, however, more research is urgently needed to clarify whether breast feeding might even have negative consequences for risk of overweight and diabetogenic disturbances when the mother suffers from a metabolic disorder. From a more general perspective, breast feeding and its long-term consequences are an important paradigm for "perinatal programming" of health and disease.

Abstract
Epidemiological studies demonstrated a clear phenomenological association between low birth weight and increased cardiometabolic risk later in life, very similar to that in high birth weight subjects. Pre- and/or neonatal overfeeding appears to be an etiological clue. In animal studies, irrespective of birth weight neonatal over-nutrition leads to later overweight, impaired glucose tolerance and cardiometabolic alterations. Probably, perinatally acquired alterations of DNA methylation patterns of gene promoters of central nervous regulators of body weight and metabolism play a key role in mediating these relationships. In humans, the long-term impact of neonatal nutrition is conclusively demonstrated by studies on the consequences of breastfeeding vs. formula-feeding. Taken together, the quantity and quality of nutrition during neonatal life plays a critical role, beyond prenatal development, in the long-term programming of health and disease. This opens a variety of opportunities and challenges to primarily prevent chronic diseases, e.g. the metabolic syndrome.

Abstract
Unfavorable maternal diet during pregnancy can predispose the offspring to diseases later in life, such as hypertension, metabolic syndrome, and obesity. However, the molecular basis for this phenomenon of "developmental programming" is poorly understood. We have recently shown that a diet nutritionally optimized for pregnancy can nevertheless be harmful in the context of diabetic pregnancy in the mouse, associated with a high incidence of neural tube defects and intrauterine growth restriction. We hypothesized that placental abnormalities may contribute to impaired fetal growth in these pregnancies, and therefore investigated the role of maternal diet in the placenta. LabDiet 5015 diet was associated with reduced placental growth, commencing at midgestation, when compared to pregnancies in which the diabetic dam was fed LabDiet 5001 maintenance chow. Furthermore, by quantitative RT-PCR we identify 34 genes whose expression in placenta at midgestation is modulated by diet, diabetes, or both, establishing biomarkers for gene-environment interactions in the placenta. These results implicate maternal diet as an important factor in pregnancy complications and suggest that the early phases of placenta development could be a critical time window for developmental origins of adult disease.

Abstract
Adverse events during intrauterine life may program organ growth and favor disease later in life. This is the usually called 'Barker's hypothesis'. Increasing evidence suggests that conditions like vascular disease, hypertension, metabolic syndrome, and type 2 diabetes mellitus are programmed during the early stages of fetal development and become manifest in late stages of life, when there is an added impact of lifestyle and other conventional acquired environmental risk factors that interact with genetic factors. The aim of this review was to provide additional, updated evidence to support the association between intrauterine fetal health and increased prevalence of chronic non-communicable diseases in adulthood. Various potential cellular and molecular mechanisms proposed to be related to the above hypothesis are discussed, including endothelial function, oxidative stress, insulin resistance, and mitochondrial function.

Abstract
Differences in nutritional experiences during sensitive periods in early life, both before and after birth, can program a person's future development, metabolism, and health. A better scientific understanding of early nutrition programming holds enormous potential for implementing preventive strategies to enhance individuals' long-term health, well-being, and performance. This understanding could reduce costs of health care and social services and may enhance the wealth of societies. The Early Nutrition Programming Project (EARNEST) brought together a multidisciplinary team of international scientists and leaders in key areas of the early nutrition programming field from 40 major research centers across 16 European countries. The project had a total budget of 16.5 million Euros and was funded by the European Communities under the Sixth Framework Program for Research and Technical Development and coordinated by the Children's Hospital at Ludwig-Maximilians-University of Munich. The integrated program of work combined experimental studies in humans, prospective observational studies, and mechanistic animal work, including physiologic studies, cell culture models, and molecular biology techniques. The project lasted from April 2005 to October 2010. After the end of the project, the Early Nutrition Academy (http://www.early-nutrition.org) continues to serve as a platform for the exchange of information, scientific collaboration, and training activities in the area of programming. This article highlights some of the scientific results, achievements, and efforts of EARNEST.

Abstract
Alterations of the intrauterine and neonatal environment may predispose for disorders and diseases throughout later life (perinatal programming). Especially, hormones and nutrients are dose-dependent organizers of the developing organism. Studies in offspring of diabetic mothers (ODM) have paradigmatically contributed to the perception of this developmental principle and our understanding of causal mechanisms. Fetal and neonatal hyperinsulinism in consequence of materno-fetal hyperglycaemia is the pathognomic feature in ODM. Epidemiological, clinical, as well as experimental data indicate that both insulin and glucose, when occurring in elevated concentrations during perinatal life, may epigenetically program a predisposition for obesity and diabetes later on. Similar may occur due to pre- and neonatal overfeeding. From a clinical point of view, avoidance of materno-fetal overnutrition, universal diabetes screening in all pregnant women and adequate therapy of all forms of diabetes during pregnancy, as well as avoidance of neonatal overfeeding are therefore recommended. These measures might serve as causal approaches of a genuine prevention to the benefit of long-term offspring health.

Abstract
Epidemiological and experimental studies have led to the hypothesis of the fetal origin of adult diseases, suggesting that some adult diseases might be determined before birth by altered fetal development. Maternal diabetes subjects the fetus to an adverse environment that has been demonstrated to result in metabolic, cardiovascular and renal impairment in the offspring. The growing amount of obesity in young females in developed and some developing countries should contribute to increasing the incidence of diabetes among pregnant women. In this review, we discuss how renal and extrarenal mechanisms participate in the genesis of hypertension induced by a diabetic status during fetal development.

Abstract
AIMS/HYPOTHESIS Pregnancies complicated by diabetes have a higher risk of adverse outcomes for mothers and children, including predisposition to disease later in life, e.g. metabolic syndrome and hypertension. We hypothesised that adverse outcomes from diabetic pregnancies may be linked to compromised placental function, and sought to identify cellular and molecular abnormalities in diabetic placenta. METHODS Using a mouse model of diabetic pregnancy, placental gene expression was assayed at mid-gestation and cellular composition analysed at various stages. Genome-wide expression profiling was validated by quantitative PCR and tissue localisation studies were performed to identify cellular correlates of altered gene expression in diabetic placenta. RESULTS We detected significantly altered gene expression in diabetic placenta for genes expressed in the maternal and those expressed in the embryonic compartments. We also found altered cellular composition of the decidual compartment. In addition, the junctional and labyrinth layers were reduced in diabetic placenta, accompanied by aberrant differentiation of spongiotrophoblast cells. CONCLUSIONS/INTERPRETATION Diabetes during pregnancy alters transcriptional profiles in the murine placenta, affecting cells of embryonic and maternal origin, and involving several genes not previously implicated in diabetic pregnancies. The molecular changes and abnormal differentiation of multiple cell types precede impaired growth of junctional zone and labyrinth, and of placenta overall. Regardless of whether these changes represent direct responses to hyperglycaemia or are physiological adaptations, they are likely to play a role in pregnancy complications and outcomes, and to have implications for developmental origins of adult disease.

Abstract
Enriched as well as impoverished or adverse perinatal environment plays an essential role in the development and refinement of neuronal pathways, which are the neural substrate of intellectual capacity and socioemotional competence. Perinatal experience and learning events continuously interact with the adaptive shaping of excitatory, inhibitory, and neuromodulatory synaptic as well as the endocrine stress systems, including the neuronal corticotropin-releasing factor (CRF) pathways. Adverse environments, such as stress and emotional deprivation can not only delay experience-dependent maturation of these pathways, but also induce permanent changes in prefronto-cortical wiring patterns. We assume that such dysfunctional connections are the neuronal basis for the development of psychosocially induced mental disorders during later life. The aim of this review is to focus on the impact of perinatal stress on the neuronal and synaptic reorganization during brain development and possible implications for the etiology and therapy of mental disorders such as ADHD.

Abstract
Aim We aimed to characterize the lasting effect of moderate caloric restriction during early pregnancy on offspring energy homeostasis, by focusing on the effects on food intake and body weight as well as on the insulin and leptin systems. Methods Male and female offspring of 20% caloric restricted dams (from 1 to 12 days of pregnancy) (CR) and from control dams were studied. These animals were fed after weaning with a normal-fat (NF) diet until the age of 4 months, and then moved to a high-fat (HF) diet. Blood parameters were measured under fed and 14-h fasting conditions at different ages (2, 4 and 5 months). Food preferences were also assessed in adult animals. Results Accumulated caloric intake from weaning to the age of 5 months was higher in CR animals compared with their controls, and this resulted in higher body weight in adulthood in males, but not in females. Both male and female CR animals already showed higher insulin levels at the age of 2 months, under fed conditions, and higher HOMA-IR from the age of 4 months, compared with their controls. CR male animals, but not females, displayed higher preference for fat-rich food than their controls in adulthood and higher circulating leptin levels when they were under HF diet. Conclusion It is suggested that hyperinsulinemia may play a role in the etiology of hyperphagia in the offspring of caloric restricted animals during gestation, with different outcomes on body weight depending on the gender, which could be associated with different programming effects on later leptin resistance.

Abstract
AIM Prenatal and neonatal overfeeding programs a permanent obesity and diabetes disposition, e.g., due to induction of hypothalamic insulin resistance. We investigated acquired alterations of the DNA methylation pattern of the hypothalamic insulin receptor promoter (IRP) which might be an underlying molecular mechanism. METHODS Neonatal overfeeding was induced by rearing Wistar rats in small litters (SL). Methylation of CpG-dinucleotides of the hypothalamic IRP was mapped using bisulfite sequencing. RESULTS Neonatal overfeeding led to rapid early weight gain, resulting in a metabolic syndrome phenotype, i.e., obesity, hyperleptinemia, hyperglycemia, hyperinsulinemia, and increased insulin/glucose-ratio. The proportion of animals carrying any methylated CpG residue in the 322 bp CpG island of the IRP was increased in neonatally overfed SL rats (n=8), as compared to controls (n=8; P=0.04). Moreover, the mean percentage of methylated CpG positions was also higher in SL rats (P=0.01). Over both groups, neonatal blood glucose levels were positively correlated to the extent of promoter methylation (r=0.52; P=0.04). CONCLUSIONS This study characterizes for the first time the IRP epigenomically in any species and tissue. Our data reveal that the IRP is vulnerable to hypermethylation due to overnutrition, probably especially glucose-dependent in a dose-response manner. This paradigmatically indicates the impact of nutrient-dependent epigenetic malprogramming, leading to a "diabesity" disposition which may become pathogenic throughout life.

Abstract
Altered nutritional experiences such as undernutrition, overnutrition, and modified milk formula in the immediate postnatal life via the phenomenon of metabolic programming have been identified as one of the components in the etiology of metabolic syndrome. We have developed a rat model in which an altered dietary experience in the form of a high-carbohydrate (HC) milk formula in the immediate postnatal life of rat pups results in chronic hyperinsulinemia and adult-onset obesity in these rats. The HC dietary modification causes functional alterations in pancreatic islets and the hypothalamus during the period of the dietary modification. These early adaptations in islets (supporting hyperinsulinemia) and the hypothalamus (supporting hyperphagia and increased body weight gain) persist in the postweaning period despite withdrawal of the HC milk formula at the time of weaning. In female rat pups receiving the HC milk formula, metabolic programming effects translate into an adverse (hyperinsulinemic, hyperleptinemic, and obese) intrauterine environment during pregnancy, causing spontaneous transfer of the maternal phenotype to the progeny (generational effect). Our results suggest that alterations in feeding practices for babies (early introduction of cereals, fruits, etc.) and babies born to obese/hyperinsulinemic mothers may be contributing factors for the obesity epidemic prevalent in developed and developing countries.

Abstract
Over the last decade there has been a striking increase in the early onset of metabolic disease, including obesity and diabetes. The regulation of energy homeostasis is complex and involves the intricate integration of peripheral and central systems, including the hypothalamus. This review provides an overview of the development of brain circuitry involved in the regulation of energy homeostasis as well as recent findings related to the impact of both prenatal and postnatal maternal environment on the development of these circuits. There is surprising evidence that both overnutrition and undernutrition impact the development of these circuits in a similar manner as well as having similar consequences of increased obesity and diabetes later in life. There is also a special focus on relevant species differences in the development of hypothalamic circuits. A deeper understanding of the mechanisms involved in the development of brain circuitry is needed to fully understand how the nutritional and/or maternal environments impact the functional circuitry as well as the behavior and physiological outcomes.

Abstract
Obesity is a major public health problem of pandemic proportion. Despite its high prevalence and widespread distribution (consistent with a common underlying etiology), clinical psychologists and primary care physicians routinely approach the problem with individualized but often ineffective treatments like psychotherapy and pharmacotherapy, or propose alterations to specific components of the 'toxic environment', cultural influences, and psychosocial factors purported to cause overeating. This paper presents an alternative perspective and proposes a potential framework for assisting health professionals in developing rational approaches to education about and preventive treatment of obesity based on the role of factors in early life that contribute to personality and behavior and which over time lead to obesity and its maintenance.

Abstract
Pre- and neonatal overfeeding programmes a permanent obesity disposition and accompanying diabetic and cardiovascular disorders, by unknown mechanisms. We proposed that early overfeeding may alter DNA methylation patterns of hypothalamic promoter regions of genes critically involved in the lifelong regulation of food intake and body weight. We induced neonatal overfeeding by rearing Wistar rats in small litters (SL) and thereafter mapped the DNA methylation status of CpG dinucleotides of gene promoters from hypothalamic tissue, using bisulfite sequencing. Neonatal overfeeding led to rapid early weight gain, resulting in a metabolic syndrome phenotype, i.e. obesity, hyperleptinaemia, hyperglycaemia, hyperinsulinaemia, and an increased insulin/glucose ratio. Accompanying, without group difference to controls, the promoter of the main orexigenic neurohormone, neuropeptide Y, was methylated at low levels (i.e. < 5%). In contrast, in SL rats the hypothalamic gene promoter of the main anorexigenic neurohormone, proopiomelanocortin (POMC), showed hypermethylation (P < 0.05) of CpG dinucleotides within the two Sp1-related binding sequences (Sp1, NF-kappaB) which are essential for the mediation of leptin and insulin effects on POMC expression. Consequently, POMC expression lacked upregulation, despite hyperleptinaemia and hyperinsulinaemia. Accordingly, the extent of DNA methylation within Sp1-related binding sequences was inversely correlated to the quotients of POMC expression/leptin (P = 0.02) and POMC expression/insulin (P < 0.001), indicating functionality of acquired epigenomic alterations. These data for the first time demonstrate a nutritionally acquired alteration of the methylation pattern and, consequently, the regulatory 'set point' of a gene promoter that is critical for body weight regulation. Our findings reveal overfeeding as an epigenetic risk factor of obesity programming and consecutive diabetic and cardiovascular disorders and diseases, in terms of the metabolic syndrome.

Abstract
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.
