Abstract
Adults who had non-edematous severe acute malnutrition (SAM) during infancy (i.e., marasmus) have worse glucose tolerance and beta-cell function than survivors of edematous SAM (i.e., kwashiorkor). We hypothesized that wasting and/or stunting in SAM is associated with lower glucose disposal rate (M) and insulin clearance (MCR) in adulthood.We recruited 40 nondiabetic adult SAM survivors (20 marasmus survivors (MS) and 20 kwashiorkor survivors (KS)) and 13 matched community controls. We performed 150-minute hyperinsulinaemic, euglycaemic clamps to estimate M and MCR. We also measured serum adiponectin, anthropometry, and body composition. Data on wasting (weight-for-height) and stunting (height-for-age) were abstracted from the hospital records.Children with marasmus had lower weight-for-height z-scores (WHZ) (-3.8 ± 0.9 vs. -2.2 ± 1.4; P < 0.001) and lower height-for-age z-scores (HAZ) (-4.6 ± 1.1 vs. -3.4 ± 1.5; P = 0.0092) than those with kwashiorkor. As adults, mean age (SD) of participants was 27.2 (8.1) years; BMI was 23.6 (5.0) kg/m2. SAM survivors and controls had similar body composition. MS and KS and controls had similar M (9.1 ± 3.2; 8.7 ± 4.6; 6.9 ± 2.5 mg.kg-1.min-1 respectively; P = 0.3) and MCR. WHZ and HAZ were not associated with M, MCR or adiponectin even after adjusting for body composition.Wasting and stunting during infancy are not associated with insulin sensitivity and insulin clearance in lean, young, adult survivors of SAM. These data are consistent with the finding that glucose intolerance in malnutrition survivors is mostly due to beta-cell dysfunction.

Abstract
The Cannabis sativa plant has historically been used for both recreational and medical purposes. With the recent surge in recreational use of cannabis among adolescents and adults in particular, there is an increased obligation to determine the short- and long-term effects that consuming this plant may have on several aspects of the human psyche and body. The goal of this article was to examine the negative effects of obesity, and how the use of Δ9-tetrahydrocannibinol (THC) or cannabidiol (CBD) can impact rates of this global pandemic at different timepoints of life. Conflicting studies have been reported between adult and adolescents, as there are reports of THC use leading to increased weight due to elevated appetite and consumption of food, while others observed a decrease in overall body weight due to the regulation of omega-6/omega-3 endocannabinoid precursors and a decrease in energy expenditure. Studies supported a positive correlation between prenatal cannabis use and obesity rates in the children as they matured. The data did not indicate a direct connection between prenatal THC levels in cannabis and obesity rates, but that this development may occur due to prenatal THC consumption leading to low birthweight, and subsequent obesity. There are few studies using animal models that directly measure the effects that prenatal THC administration on obesity risks among offspring. Thus, this is a critical area for future studies using a developmental framework to examine potential changes in risk across development.

Abstract
Background: Perinatal factors including gestational age, birthweight, size for gestational age, delivery route, maternal parity, maternal age, maternal education, socioeconomic status, race, and sex, are associated with the future risk of obesity and co-morbid conditions. This study evaluated the relationship of birthweight for gestational age and perinatal factors with severe obesity and dyslipidemia in adulthood. Methods: We conducted a population-based, retrospective birth cohort study of infants born to residents of Olmsted County, MN between 1976 and 1982. Outcomes were assessed after age 18 years until October 2020, including severe obesity (BMI ≥ 40 kg/m2) and dyslipidemia (total cholesterol ≥200 mg/dL, non-high density lipoprotein [non-HDL] cholesterol ≥145 mg/dL or HDL cholesterol <40 mg/dL). We obtained mother’s age, education level, and parity as well as newborn sex, race, type of delivery, single/multiple birth, gestational age, and birthweight from birth certificate data. Individual-level socioeconomic status (SES) of the household at birth was determined with the HOUSES index. Results: Of 10 938 birth cohort subjects, 7394 had clinic visits after age 18 years and were included, with 2630 having severe obesity (n = 798) or dyslipidemia (n = 2357) as adults. In multivariable models, female sex, singleton birth, less maternal education, and lower SES defined by HOUSES were independently associated with an increased risk of severe obesity in adulthood. Non-white race, singleton birth, and lower birthweight were independently associated with adult dyslipidemia. Birthweight for gestational age was not associated with severe obesity or dyslipidemia. Conclusion: Perinatal factors were associated with both severe obesity and dyslipidemia in adulthood. Lower SES at birth was predictive of severe obesity in adulthood, highlighting the opportunity to investigate modifiable perinatal social determinants to reduce the risk of severe obesity.

Abstract
Disruption of the in utero environment can have dire consequences on fetal growth and development. Intrauterine growth restriction (IUGR) is a pathological condition by which the fetus deviates from its expected growth trajectory, resulting in low birth weight and impaired organ function. The developmental origins of health and disease (DOHaD) postulates that IUGR has lifelong consequences on offspring well-being, as human studies have established an inverse relationship between birth weight and long-term metabolic health. While these trends are apparent in epidemiological data, animal studies have been essential in defining the molecular mechanisms that contribute to this relationship. One such mechanism is cellular stress, a prominent underlying cause of the metabolic syndrome. As such, this review considers the role of oxidative stress, mitochondrial dysfunction, endoplasmic reticulum (ER) stress, and inflammation in the pathogenesis of metabolic disease in IUGR offspring. In addition, we summarize how uncontrolled cellular stress can lead to programmed cell death within the metabolic organs of IUGR offspring.

Abstract
Key points Previous studies in fetuses with intrauterine growth restriction (IUGR) have shown that adrenergic dysregulation was associated with low insulin concentrations and greater insulin sensitivity. Although whole‐body glucose clearance is normal, 1‐month‐old lambs with IUGR at birth have higher rates of hindlimb glucose uptake, which may compensate for myocyte deficiencies in glucose oxidation. Impaired glucose‐stimulated insulin secretion in IUGR lambs is due to lower intra‐islet insulin availability and not from glucose sensing. We investigated adrenergic receptor (ADR) β2 desensitization by administering oral ADRβ modifiers for the first month after birth to activate ADRβ2 and antagonize ADRβ1/3. In IUGR lambs ADRβ2 activation increased whole‐body glucose utilization rates and insulin sensitivity but had no effect on isolated islet or myocyte deficiencies. IUGR establishes risk for developing diabetes. In IUGR lambs we identified disparities in key aspects of glucose‐stimulated insulin secretion and insulin‐stimulated glucose oxidation, providing new insights into potential mechanisms for this risk.
Abstract Placental insufficiency causes intrauterine growth restriction (IUGR) and disturbances in glucose homeostasis with associated β adrenergic receptor (ADRβ) desensitization. Our objectives were to measure insulin‐sensitive glucose metabolism in neonatal lambs with IUGR and to determine whether daily treatment with ADRβ2 agonist and ADRβ1/β3 antagonists for 1 month normalizes their glucose metabolism. Growth, glucose‐stimulated insulin secretion (GSIS) and glucose utilization rates (GURs) were measured in control lambs, IUGR lambs and IUGR lambs treated with adrenergic receptor modifiers: clenbuterol atenolol and SR59230A (IUGR‐AR). In IUGR lambs, islet insulin content and GSIS were less than in controls; however, insulin sensitivity and whole‐body GUR were not different from controls. Of importance, ADRβ2 stimulation with β1/β3 inhibition increases both insulin sensitivity and whole‐body glucose utilization in IUGR lambs. In IUGR and IUGR‐AR lambs, hindlimb GURs were greater but fractional glucose oxidation rates and ex vivo skeletal muscle glucose oxidation rates were lower than controls. Glucose transporter 4 (GLUT4) was lower in IUGR and IUGR‐AR skeletal muscle than in controls but GLUT1 was greater in IUGR‐AR. ADRβ2, insulin receptor, glycogen content and citrate synthase activity were similar among groups. In IUGR and IUGR‐AR lambs heart rates were greater, which was independent of cardiac ADRβ1 activation. We conclude that targeted ADRβ2 stimulation improved whole‐body insulin sensitivity but minimally affected defects in GSIS and skeletal muscle glucose oxidation. We show that risk factors for developing diabetes are independent of postnatal catch‐up growth in IUGR lambs as early as 1 month of age and are inherent to the islets and myocytes. Previous studies in fetuses with intrauterine growth restriction (IUGR) have shown that adrenergic dysregulation was associated with low insulin concentrations and greater insulin sensitivity. Although whole‐body glucose clearance is normal, 1‐month‐old lambs with IUGR at birth have higher rates of hindlimb glucose uptake, which may compensate for myocyte deficiencies in glucose oxidation. Impaired glucose‐stimulated insulin secretion in IUGR lambs is due to lower intra‐islet insulin availability and not from glucose sensing. We investigated adrenergic receptor (ADR) β2 desensitization by administering oral ADRβ modifiers for the first month after birth to activate ADRβ2 and antagonize ADRβ1/3. In IUGR lambs ADRβ2 activation increased whole‐body glucose utilization rates and insulin sensitivity but had no effect on isolated islet or myocyte deficiencies.

Abstract
Intrauterine growth restriction (IUGR) leads to reduced birth weight and the development of metabolic diseases such as Type 2 diabetes in adulthood. Mitochondria dysfunction and oxidative stress are commonly found in key tissues (pancreatic islets, liver, and skeletal muscle) of IUGR individuals. In this review, we explore the role of oxidative stress in IUGR-associated diabetes etiology.

Abstract
PURPOSE OF REVIEW Overweight and obesity are well-established risk factors for type 2 diabetes. However, a substantial number of individuals develop the disease at underweight or normal weight. In this review, we discuss the epidemiology of type 2 diabetes in non-overweight adults; pose questions about etiology, pathophysiology, diagnosis, and prognosis; and examine implications for prevention and treatment. RECENT FINDINGS In population-based studies, the prevalence of type 2 diabetes ranged from 1.4-10.9%. However, the prevalence of type 2 diabetes in individuals with BMI < 25 kg/m2 ranged from 1.4-8.8%. In countries from Asia and Africa, the proportion of individuals with diabetes who were underweight or normal weight ranged from 24 to 66%, which is considerably higher than the US proportion of 10%. Impairments in insulin secretion, in utero undernutrition, and epigenetic alterations to the genome may play a role in diabetes development in this subgroup. A substantial number of individuals with type 2 diabetes, particularly those with recent ancestry from Asia or Africa, are underweight or normal weight. Future research should consist of comprehensive studies of the prevalence of type 2 diabetes in non-overweight individuals; studies aimed at understanding gaps in the mechanisms, etiology, and pathophysiology of diabetes development in underweight or normal weight individuals; and trials assessing the effectiveness of interventions in this population.

Abstract
Intrauterine growth restriction (IUGR) is the second leading cause of perinatal mortality and predisposes offspring to metabolic disorders at all stages of life. Muscle-centric fetal adaptations reduce growth and yield metabolic parsimony, beneficial for IUGR fetal survival but detrimental to metabolic health after birth. Epidemiological studies have reported that IUGR-born children experience greater prevalence of insulin resistance and obesity, which progresses to diabetes, hypertension, and other metabolic disorders in adulthood that reduce quality of life. Similar adaptive programming in livestock results in decreased birth weights, reduced and inefficient growth, decreased carcass merit, and substantially greater mortality rates prior to maturation. High rates of glucose consumption and metabolic plasticity make skeletal muscle a primary target for nutrient-sparing adaptations in the IUGR fetus, but at the cost of its contribution to proper glucose homeostasis after birth. Identifying the mechanisms underlying IUGR pathophysiology is a fundamental step in developing treatments and interventions to improve outcomes in IUGR-born humans and livestock. In this review, we outline the current knowledge regarding the adaptive restriction of muscle growth and alteration of glucose metabolism that develops in response to progressively exacerbating intrauterine conditions. In addition, we discuss the evidence implicating developmental changes in β adrenergic and inflammatory systems as key mechanisms for dysregulation of these processes. Lastly, we highlight the utility and importance of sheep models in developing this knowledge.

Abstract
OBJECTIVES We aimed to assess the individual dose-response effects of eight maternal polymorphisms encoding polycyclic aromatic hydrocarbon-metabolizing and DNA-repair genes on prenatal cotinine levels according to infant birth size. METHODS In total, 3263 Japanese pregnant women were assigned to five groups based on plasma cotinine levels during the 8th month of pregnancy, as measured using ELISA (cut-offs: 0.21, 0.55, 11.48, and 101.67ng/mL). Analyses were performed using multiple linear regression. RESULTS Birth weight reduction showed a dose-dependent relationship with prenatal cotinine levels (P for trend<0.001). When considering the specific aromatic hydrocarbon receptor (AHR) (G>A, Arg554Lys; db SNP ID: rs2066853) and X-ray cross-complementing gene 1 (XRCC1) (C>T, Arg194Trp, rs1799782) genotypes, a larger birth weight reduction was noted among infants born to mothers with the highest cotinine level. CONCLUSION Infants born to women with specific AHR and XRCC1 genotypes may have higher genetic risks for birth weight reduction.

Abstract
Placental insufficiency leads to intrauterine growth restriction (IUGR) and a lifelong risk of developing type 2 diabetes. Impaired islet development in the growth restricted fetus, including decreased β-cell replication, mass, and insulin secretion, is strongly implicated in the pathogenesis of later life type 2 diabetes. Currently, standard medical management of a woman with a pregnancy complicated by placental insufficiency and fetal IUGR is increased fetal surveillance and indicated preterm delivery. This leads to the dual complications of IUGR and preterm birth - both of which may increase the lifelong risk for type 2 diabetes. In order to develop therapeutic interventions in IUGR pregnancies complicated by placental insufficiency and decrease the risk of later development of type 2 diabetes in the offspring, the mechanisms responsible for impaired islet development in these cases must be determined. This review focuses on current investigations testing the hypothesis that decreased nutrient supply to the IUGR fetus inhibits an intra-islet hepatocyte growth factor - vascular endothelial growth factor A (HGF - VEGFA) feed forward signaling pathway and that this is responsible for developmental islet defects.

Abstract
Genome wide association studies have identified ~100 loci associated with body mass index (BMI). Persons with low birth weight have an increased risk of metabolic disorders. We postulate that normal mechanisms of body weight regulation are disrupted in subjects with low birth weight. The present analyses included 2215 African American women from the Black Women's Health Study, and were based on genotype data on 20 BMI-associated loci and self-reported data on birth weight, weight at age 18 and adult weight. We used general linear models to assess the association of individual single-nucleotide polymorphisms (SNPs) with BMI at age 18 and later in adulthood within strata of birth weight (above and below the median, 3200 g). Three SNPs (rs1320330 near TMEM18, rs261967 near PCSK1 and rs17817964 in FTO), and a genetic score combining these three variants, showed significant interactions with birth weight in relation to BMI. Among women with birth weight <3200 g, there was an inverse association between genetic score and BMI; beta-coefficient=-0.045 (95% confidence intervals (CI) -0.104, 0.013) for BMI at age 18, and -0.055 (95% CI -0.112, 0.002) for adult BMI. Among women with birth weight ⩾3200 g, genetic score was positively associated with BMI: beta-coefficient=0.110 (95% CI 0.051, 0.169) for BMI at age 18 (P for interaction=0.0002), and 0.112 (95% CI 0.054, 0.170) for adult BMI (P for interaction<0.0001). Because TMEM18, PCSK1 and FTO are highly expressed in the central nervous system (CNS), our results suggest that low-birth weight may disrupt mechanisms of CNS body weight regulation.

Abstract
Low birth weight and a rapid weight gain in early childhood may lead to an increased risk for developing cardiovascular disease later in life, such as hypertension and dyslipidaemia. In this study, we examined the associations between size at birth, relative weight gain in infancy and childhood with specific cardiovascular disease risk factors in early adulthood. Adolescents (n=1935) from the Birth to Twenty plus (BT20+) cohort were included in the analysis. The following were treated as exposure variables: weight at birth, and relative conditional weight gain (CW), independent of height, between ages 0-24 months and 24-48 months. Outcomes were serum lipids and body composition variables at age 18 years. After adjusting for sex and other confounders, early life exposures were not associated with adolescent lipid profile. Following adjustment for sex and height (body size), birth weight [β=0.704 (0.40, 1.01)], CW 0-24 [β=1.918 (1.56, 2.28)] and CW24-48 [β=1.485 (1.14, 1.82)] accounted for 48% of the variance in fat mass. However, birth weight [β=0.773 (0.54, 1.01)], CW 0-24 [β=1.523 (1.24, 1.80)] and CW24-48 [β=1.226 (0.97, 1.49)] were also positively predicted and accounted for 71% of the variance in fat mass in adolescence (P<0.05). Our data suggests that birth weight and weight gain during infancy and early childhood independent of linear growth are related to adolescent body composition but not blood lipid profiles in an urban African population.

Abstract
AbstractObjectiveThe present study aimed to investigate the prevalence of metabolic syndrome (MetS) in 7- to 17-year-old children and adolescents in China and to examine the relationship between MetS and its associated early-life factors.DesignData were collected using a standard parent/guardian questionnaire in a face-to-face interview. Each participant underwent a complete anthropometric evaluation. MetS was defined according to the criteria of the International Diabetes Federation (IDF; 2007) for children and adolescents.SettingGuangzhou, a large city in South China, September 2013.SubjectsA total of 1770 children and adolescents were enrolled in the study, including 913 girls (51·6 %) and 857 boys (48·4 %).ResultsThe overall prevalence of MetS in children and adolescents was 1·1 % (n 19), which was higher in boys (1·4 %) than in girls (0·8 %). Multivariate analysis indicated that high birth weight was significantly associated with abdominal obesity (OR=2·86; 95 % CI 1·62, 5·06) and MetS (OR=3·61; 95 % CI 1·33, 9·82). Furthermore, >6 months of maternal breast-feeding was inversely associated with MetS (OR=0·39; 95 % CI 0·16, 0·98).ConclusionBased on IDF criteria, the prevalence of MetS among southern Chinese children was significantly lower than that in other populations. High birth weight was significantly associated with abdominal obesity and MetS, and breast-feeding for longer than 6 months was inversely associated with MetS in South China.

Abstract
AIMS/HYPOTHESIS The aim of this work was to investigate the prospective relationship between low birthweight (LBW) and type 2 diabetes risk later in life and the mediation effects of type 2 diabetes biomarkers linking LBW to type 2 diabetes risk. METHODS We measured baseline plasma concentrations of various type 2 diabetes biomarkers in 1,259 incident type 2 diabetes cases and 1,790 controls in the Women's Health Initiative-Observational Study. Self-report birthweights of the participants were recorded. The total effect of LBW on type 2 diabetes risk was partitioned into effects that were mediated by a specific biomarker and effects that were not mediated by this biomarker, using counterfactual model-based mediation analysis. RESULTS LBW was significantly associated with increased risk of type 2 diabetes. Compared with women with birthweight 3.63-4.54 kg, women with LBW (<2.72 kg) had a multivariable-adjusted OR of 2.15 (95% CI, 1.54, 3.00). Insulin resistance (indicated by HOMA-IR) mediated 47% of the total effect. Decreased sex hormone-binding globulin (SHBG) concentration accounted for 24%, elevated E-selectin concentration accounted for 25% and increased systolic blood pressure accounted for 8% of the total effect of LBW on type 2 diabetes risk. (Due to interactions among different mediators, the sum of each individual mediator's contribution could exceed 100%, without an upper limit.) CONCLUSIONS/INTERPRETATION LBW is directly predictive of higher risk of type 2 diabetes later in life. The effect of LBW on type 2 diabetes risk seems mainly mediated by insulin resistance, which is further explained by circulating levels of SHBG and E-selectin and systolic blood pressure. The study provides potential risk stratification in a population at greater risk of developing type 2 diabetes.

Abstract
AIMS/HYPOTHESIS Lower birthweight (a marker of fetal undernutrition) is associated with higher risks of type 2 diabetes and cardiovascular disease (CVD) and could explain ethnic differences in these diseases. We examined associations between birthweight and risk markers for diabetes and CVD in UK-resident white European, South Asian and black African-Caribbean children. METHODS In a cross-sectional study of risk markers for diabetes and CVD in 9- to 10-year-old children of different ethnic origins, birthweight was obtained from health records and/or parental recall. Associations between birthweight and risk markers were estimated using multilevel linear regression to account for clustering in children from the same school. RESULTS Key data were available for 3,744 (66%) singleton study participants. In analyses adjusted for age, sex and ethnicity, birthweight was inversely associated with serum urate and positively associated with systolic BP. After additional height adjustment, lower birthweight (per 100 g) was associated with higher serum urate (0.52%; 95% CI 0.38, 0.66), fasting serum insulin (0.41%; 95% CI 0.08, 0.74), HbA1c (0.04%; 95% CI 0.00, 0.08), plasma glucose (0.06%; 95% CI 0.02, 0.10) and serum triacylglycerol (0.30%; 95% CI 0.09, 0.51) but not with BP or blood cholesterol. Birthweight was lower among children of South Asian (231 g lower; 95% CI 183, 280) and black African-Caribbean origin (81 g lower; 95% CI 30, 132). However, adjustment for birthweight had no effect on ethnic differences in risk markers. CONCLUSIONS/INTERPRETATION Birthweight was inversely associated with urate and with insulin and glycaemia after adjustment for current height. Lower birthweight does not appear to explain emerging ethnic difference in risk markers for diabetes.

Abstract
Metabolic syndrome (MetS) is a clinical condition that includes multiple cardiovascular disease risk factors, including obesity, high blood pressure or hypertension, dyslipidemia, and abnormal glucose metabolism. The core metabolic abnormality in MetS is insulin resistance, or impaired insulin-mediated glucose regulation that results in elevated plasma insulin concentration. MetS greatly increases the risk for diabetes, atherosclerosis, and adverse metabolic and cardiovascular outcomes. The syndrome is present in over 25 % of adults in the U.S., with higher rates among racial/ethnic minority groups. Although commonly associated with adult diseases and aging, MetS has also been described in children and adolescents, but at a much lower prevalence of approximately 4-5 %. Because obesity is a key component of the syndrome, the growing childhood epidemic has raised awareness of MetS in children. The rate of MetS among obese children and adolescents is approximately 30 %, with similar racial/ethnic disparity among minority groups as among adults.

Abstract
OBJECTIVE To assess the association of birth weight with incident type 2 diabetes, and the possible mediating influence of obesity, in a large cohort of U.S. black women. RESEARCH DESIGN AND METHODS The Black Women's Health Study is an ongoing prospective study. We used Cox proportional hazards models to estimate incidence rate ratios (IRRs) and 95% CI for categories of birth weight (very low birth weight [<1,500 g], low birth weight [1,500-2,499 g], and high birth weight [≥4,000 g]) in reference to normal birth weight (2,500-3,999 g). Models were adjusted for age, questionnaire cycle, family history of diabetes, caloric intake, preterm birth, physical activity, years of education, and neighborhood socioeconomic status with and without inclusion of terms for adult BMI. RESULTS We followed 21,624 women over 16 years of follow-up. There were 2,388 cases of incident diabetes. Women with very low birth weight had a 40% higher risk of disease (IRR 1.40 [95% CI 1.08-1.82]) than women with normal birth weight; women with low birth weight had a 13% higher risk (IRR 1.13 [95% CI 1.02-1.25]). Adjustment for BMI did not appreciably change the estimates. CONCLUSIONS Very low birth weight and low birth weight appear to be associated with increased risk of type 2 diabetes in African American women, and the association does not seem to be mediated through BMI. The prevalence of low birth weight is especially high in African American populations, and this may explain in part the higher occurrence of type 2 diabetes.

Abstract
In Japan, the rate of low birth weight infants has increased, due to an increase in the number of women who smoke or are lean. A recent study showed that low birth weight was associated with a high adult waist-to-height ratio in adult Japanese women, but little data is available concerning children. In this cross-sectional study with 568 subjects (276 boys and 292 girls), we examined the association between birth weight and waist-to-height ratio in 7- or 8-year-old Japanese children, all born at full term. The mothers of the subjects responded to a questionnaire about the weight of the children at birth, and physical data were collected from the results of measurements conducted at each school. We divided the subjects into two groups by the median of the birth weight (3,000 g) by sex to elucidate the effects of birth weight on the waist-to-height ratio. There were 119 boys and 164 girls and 157 boys and 128 girls in the < 3,000 g and ≥ 3,000 g birth weight groups, respectively. The Mann-Whitney U test was used to compare the physical conditions in the two birth weight categories. Height was significantly lower in the birth weight < 3,000 g group among both the boys (P < 0.001) and girls (P < 0.001). The waist-to-height ratio was significantly higher in the < 3,000 g group in girls (P = 0.004), but not in the boys. Our results suggest that intrauterine environmental insults might have an effect on children, depending on sex.

Abstract
During our phylogenetic evolution we have selected genes, the so called thrifty genes, that can help to maximize the amount of energy stored from every consumed calorie. An imbalance in the amount of stored calories can lead to many diseases. In the early 80's the distinguished English epidemiologist David Barker, formulated a hypothesis suggesting that many events that occur during the intrauterine life and early in infancy can influence the occurrence of many diseases that will develop in adulthood. This theory proposes that under-nutrition and other insult or adverse stimulus in utero and during infancy can permanently change the body's structure, physiology and metabolism. The lasting or lifelong effects of under-nutrition will depend on the period in the development at which it occurs. The clues that led Barker to his conclusions started to be discovered when he was studying the temporal trends in the incidence of ischemic heart disease in England and Wales. Examining data found in The Hertfordshire records, collected in the beginning of the last century, he found that the rates of mortality by ischemic heart disease was much higher in children born in less affluent counties and mostly in those with low birth weight. After his initial findings a myriad of diseases have been found to be linked to low birth weight and under-nutrition in utero and in the neonatal period. These diseases were then nominated adult diseases with fetal origin. Epidemiological studies that led to these findings suggest that in utero and early postnatal life have critical importance for long-term programming of health and disease, opening unique chances for primary prevention of chronic diseases.

Abstract
OBJECTIVE To examine the relationships between birth weight and metabolic syndrome (MS) risk factors in healthy Japanese high school girls. METHODS After obtaining informed consent, we carried out health surveys for the Food Educational Program (FEP) in 2007 and 2008 in 243 healthy Japanese high school girls aged 16.4 ± 1.4 years and examined anthropometric measurements, including abdominal circumference, systolic and diastolic blood pressures (SBP and DBP, respectively), triglycerides (TG), high-density lipoprotein cholesterol (HDL), insulin, and blood glucose to calculate insulin resistance after fasting for 3 hours after lunch. Birth weight was checked by maternity record book, and food customs were recorded using a questionnaire. We analyzed the prevalence of MS risk factors by Bonferroni test following 1-way analysis of variance and their relationships with birth weight by correlation analyses. RESULTS According to criteria for MS risk factors in Japanese children and adults, the prevalence of obesity, high blood pressure, dyslipidemia, and high blood glucose was 7.4%, 9.1%, 7.0%, and 16.0%, respectively, and MS was detected in only 1 girl who had obesity and 2 more risks (high SBP and TG). Among 180 subjects who reported their birth weights, birth weights were significantly inversely related with SBP (p = 0.007), DBP (p = 0.033), TG (p = 0.009), insulin level (p = 0.047), insulin resistance ( p= 0.050), and number of metabolic risk factors (p = 0.022). Thirteen girls (7.2%) whose birth weights were lower than 2500 g had significantly higher SBP (p = 0.037), DBP (p = 0.032), TG (p = 0.011), insulin level (p=0.037), and insulin resistance (p = 0.043), than 31 girls (17.2%) with birth weights equal to or more than 3400 g. CONCLUSION The association of low birth weight could be detected to be significant with such risks of MS as SBP, DBP, TG, insulin level, and insulin resistance even in healthy Japanese high school girls, indicating the importance of follow-up and FEP for children with low birth weight for the prevention of MS in the later life.

Abstract
The 'thrifty phenotype' hypothesis proposes that the fetus adapts to an adverse intrauterine milieu by optimizing the use of a reduced nutrient supply to ensure survival, but by favoring the development of certain organs over that of others, this leads to persistent alterations in the growth and function of developing tissues. This concept has been somewhat controversial, however recent epidemiological, clinical, and animal studies provide support for the developmental origins of disease hypothesis. Underlying mechanisms include reprogramming of the hypothalamic-pituitary-adrenal axis, islet development, and insulin signaling pathways. Emerging data suggests that oxidative stress and mitochondrial dysfunction may also play a critical role in the pathogenesis of type 2 diabetes in individuals who were growth retarded at birth.

Abstract
Background Recent studies have demonstrated that low and high birth-weight at birth are risk factors of developing diabetes. The aim of this study was to determine if the abnormal birth-weight is related with hyperinsulinemia and elevated index of the Homeostasis Model assessment for Insulin Resistance (HOMA-IR) at birth, in at term newborns. Methods Newborns with gestational age between 38 and 41 weeks, products of normal pregnancies of healthy mothers aged 18 to 39 years, were eligible to participate. Small-for-gestational age (SGA) and large-for-gestational age (LGA) newborns were compared with appropriate-for-gestational (AGA) age newborns. Incomplete or unclear data about mother’s health status, diabetes, gestational diabetes, history of gestational diabetes, hypertension, pre-eclampsia, eclampsia, and other conditions that affect glucose metabolism were exclusion criteria. Hyperinsulinemia was defined by serum insulin levels ≥13.0 μU/mL and IR by HOMA-IR ≥2.60. Multiple logistic regression analysis was used to determine the odds ratio (OR) that computes the association between birth-weight (independent variable) with hyperinsulinemia and HOMA-IR index (dependent variables). Results A total of 107 newborns were enrolled; 13, 22, and 72 with SGA, LGA, and AGA, respectively. Hyperinsulinemia was identified in 2 (15.4%), 6 (27.3%), and 5 (6.9%) with SGA, LGA, and AGA (p=0.03), whereas IR in 3 (23.1%), 8 (36.4%), and 10 (13.9%) newborns with SGA, LGA and AGA (p=0.06). The LGA showed a strong association with hyperinsulinemia (OR 5.02; CI 95%, 1.15-22.3; p=0.01) and HOMA-IR (OR 3.54; CI 95%, 1.03-12.16; p=0.02); although without statistical significance, the SGA showed a tendency of association with hyperinsulinemia (OR 2.43; CI 95%, 0.43-17.3 p=0.29) and HOMA-IR (OR 1.86; CI 95%, 0.33-9.37; p=0.41). Conclusions Our results suggest that LGA is associated with hyperinsulinemia and elevated HOMA-IR at birth whereas the SGA show a tendency of association.

Abstract
BACKGROUND The prevalence of low birth weight (LBW) is a major public health issue in India (30.0%) and is the highest among South-Asian countries. Maternal autonomy or the mother's status in the household indicates her decision-making power with respect to movement, finance, healthcare use, and other household activities. Evidence suggests that autonomy of the mother is significantly associated with the child's nutritional status. Although previous studies in India reported the determinants of LBW, literature on the association between mother's autonomy and birth weight are lacking. This study, therefore, aims to examine the influence of maternal autonomy on birth weight of the newborn. METHODS The study, a secondary data analysis, examined data from the 2005-2006 National Health and Family Survey (NFHS 3) of India. A maternal autonomy score was created through proximal component factor analysis and categorized as high, medium, and low autonomy levels. The main outcome variable included birth weight of the index child obtained from health cards and mother's recall. Descriptive and logistic regression analyses were performed. RESULTS Results from the study indicate that 20.0% of the index children included in the analysis were born at LBW. Low maternal autonomy was an independent predictor of LBW (odds ratio [OR] 1.28, 95% confidence interval [CI] 1.07-1.53, p=0.007) after adjusting for other factors, and medium autonomy level was not significant. CONCLUSIONS These findings clearly indicate the importance of empowering women in India to combat the high incidence of LBW.

Abstract
BACKGROUND The widely reported inverse association between birth weight and risk of cardiovascular disease (CVD) has sparked theories about early life determinants of adult disease. Within-twin-pair analysis provides a unique opportunity to investigate whether factors shared within twin pairs influence the association. METHODS AND RESULTS In a population-based cohort of like-sexed twins with known zygosity born in Sweden from 1926 to 1958, disease-discordant twin pairs were identified through linkage to the National Inpatient and Cause of Death registers between 1973 and 2006. Co-twin-control analyses were performed on twins discordant for cardiovascular disease (n=3884), coronary heart disease (n=2668), and stroke (n=1372). Overall, inverse associations between birth weight and risk of cardiovascular diseases were seen within dizygotic but not monozygotic twin pairs. In dizygotic twins, the odds ratios for a 1-kg within-pair increase in birth weight were 0.74 (95% confidence interval, 0.56 to 0.98) for coronary heart disease and 0.57 (95% confidence interval, 0.37 to 0.88) for stroke. Conversely, no statistically significant associations were found within monozygotic twins (for coronary heart disease: odds ratio, 1.10; 95% confidence interval, 0.73 to 1.68; for stroke: odds ratio, 0.92; 95% confidence interval, 0.48 to 1.80). CONCLUSIONS We found an association between birth weight and risk of cardiovascular disease within disease-discordant dizygotic but not monozygotic twin pairs. This indicates that the association between birth weight and cardiovascular disease could be a result of common causes, and that factors that vary within dizygotic but not monozygotic twin pairs may help identify them.

Abstract
Obesity and related disorders are thought to have their roots in metabolic "thriftiness" that evolved to combat periodic starvation. The association of low birth weight with obesity in later life caused a shift in the concept from thrifty gene to thrifty phenotype or anticipatory fetal programming. The assumption of thriftiness is implicit in obesity research. We examine here, with the help of a mathematical model, the conditions for evolution of thrifty genes or fetal programming for thriftiness. The model suggests that a thrifty gene cannot exist in a stable polymorphic state in a population. The conditions for evolution of thrifty fetal programming are restricted if the correlation between intrauterine and lifetime conditions is poor. Such a correlation is not observed in natural courses of famine. If there is fetal programming for thriftiness, it could have evolved in anticipation of social factors affecting nutrition that can result in a positive correlation.

Abstract
BACKGROUND Children born with intrauterine growth retardation (IUGR) show long-term complications like non-catch-up growth and type 2 diabetes. We hypothesize that the duration of malnutrition influences the growth and pancreatic development in IUGR. The pancreatic duodenal homeobox-1 (PDX-1) expression might also be different because it links glucose metabolism to the regulation of insulin gene transcription in the pancreas. METHODS We made an IUGR rat model with a low-protein diet (8% casein) during gestational periods. Catch-up rats (CU) were given normal lab chow immediately after birth. Non-catch-up rats (NCU) were given normal lab chow after lactation periods. PDX-1 mRNA level, islet areas and intravenous glucose tolerance test (IVGTT) were assessed in each group and compared with control rats (C) at the 16th week. RESULTS The weight and length of CU and C rats were not different after 3 weeks, while NCU rats were smaller than C and CU rats (P < 0.05). In IVGTT, the 20-min and 50-min glucose level and area under the curve for glucose were increased in NCU rats compared with those values in C and CU rats (P < 0.05). The islet area of NCU rats was smaller than that of C and CU rats (P < 0.05). In contrast, PDX-1 mRNA levels of NCU rats were higher than those of C rats (P < 0.05). CU rats showed normal glucose response in IVGTT with increased islet number and size. CONCLUSIONS IUGR rats that failed to undergo catch-up growth might be prone to abnormal glucose tolerance, decreased islet size, and increased PDX-1 mRNA levels in early adult life.

Abstract
Under- and over-nutrition during pregnancy has been linked to the later development of diseases such as diabetes and obesity. Epigenetic modifications may be one mechanism by which exposure to an altered intrauterine milieu or metabolic perturbation may influence the phenotype of the organism much later in life. Epigenetic modifications of the genome provide a mechanism that allows the stable propagation of gene expression from one generation of cells to the next. This review highlights our current knowledge of epigenetic gene regulation and the evidence that chromatin remodelling and histone modifications play key roles in adipogenesis and the development of obesity. Epigenetic modifications affecting processes important to glucose regulation and insulin secretion have been described in the pancreatic β-cells and muscle of the intrauterine growth-retarded offspring, characteristics essential to the pathophysiology of type-2 diabetes. Epigenetic regulation of gene expression contributes to both adipocyte determination and differentiation in in vitro models. The contributions of histone acetylation, histone methylation and DNA methylation to the process of adipogenesis in vivo remain to be evaluated.

Abstract
Low birth weight is an important risk factor for impaired glucose tolerance and diabetes later in life. One hypothesis is that fetal beta-cells inherit a persistent defect as a developmental response to fetal malnutrition, a primary cause of intrauterine growth restriction (IUGR). Our understanding of fetal programing events in the human endocrine pancreas is limited, but several animal models of IUGR extend our knowledge of developmental programing in beta-cells. Pathological outcomes such as beta-cell dysfunction, impaired glucose tolerance, and diabetes are often observed in adult offspring from these animal models, similar to the associations of low birth weight and metabolic diseases in humans. However, the identified mechanisms underlying beta-cell dysfunction across models and species are varied, likely resulting from the different methodologies used to induce experimental IUGR, as well as from intraspecies differences in pancreas development. In this review, we first present the evidence for human beta-cell dysfunction being associated with low birth weight or IUGR. We then evaluate relevant animal models of IUGR, focusing on the strengths of each, in order to define critical periods and types of nutrient deficiencies that can lead to impaired beta-cell function. These findings frame our current knowledge of beta-cell developmental programing and highlight future research directions to clarify the mechanisms of beta-cell dysfunction for human IUGR.

Abstract
Background In recent decades immigration to Norway from Asia, Africa and Eastern Europe has increased rapidly. The aim of this study was to assess the quality of care for type 2 diabetes mellitus (T2DM) patients from these ethnic minority groups compared with the care received by Norwegians. Methods In 2006, electronic medical record data were screened at 11 practices (49 GPs; 58857 patients). 1653 T2DM patients cared for in general practice were identified. Ethnicity was defined as self-reported country of birth. Chi-squared tests, one-way ANOVAs, multiple regression, linear mixed effect models and generalized linear mixed models were used. Results Diabetes was diagnosed at a younger age in patients from the ethnic minority groups (South Asians (SA): mean age 44.9 years, Middle East/North Africa (MENA): 47.2 years, East Asians (EA): 52.0 years, others: 49.0 years) compared with Norwegians (59.7 years, p < 0.001). HbA1c, systolic blood pressure (SBP) and s-cholesterol were measured in >85% of patients in all groups with minor differences between minority groups and Norwegians. A greater proportion of the minority groups were prescribed hypoglycaemic medications compared with Norwegians (≥79% vs. 72%, p < 0.001). After adjusting for age, gender, diabetes duration, practice and physician unit, HbA1c (geometric mean) for Norwegians was 6.9% compared to 7.3-7.5% in the minority groups (p < 0.05). The proportion with poor glycaemic control (HbA1c > 9%) was higher in minority groups (SA: 19.6%, MENA: 18.9% vs. Norwegians: 5.6%, p < 0.001. No significant ethnic differences were found in the proportions reaching the combined target: HbA1c ≤ 7.5%, SBP ≤ 140 mmHg, diastolic blood pressure (DBP) ≤ 85 mmHg and total s-cholesterol ≤5.0 mmol/L (Norwegians: 25.5%, SA: 24.9%, MENA: 26.9%, EA: 26.1%, others:17.5%). Conclusions Mean age at the time of diagnosis of T2DM was 8-15 years younger in minority groups compared with Norwegians. Recording of important processes of care measures is high in all groups. Only one in four of most patient groups achieved all four treatment targets and prescribing habits may be sub-optimal. Patients from minority groups have worse glycaemic control than Norwegians which implies that it might be necessary to improve the guidelines to meet the needs of specific ethnic groups.

Abstract
OBJECTIVE To evaluate whether a coupled family history of diabetes (FHD) and low birth weight (LBW) or high birth weight (HBW) is associated with metabolic syndrome (MetS) in children and adolescents. STUDY DESIGN A total of 1262 children and adolescents age 7-15 years were randomly selected to enroll in this cross-sectional, community-based study. RESULTS In the overall population, HBW (odds ratio [OR] = 1.4; 95% confidence interval [CI] = 1.2-10.9), but not LBW (OR = 0.97; 95% CI = 0.6-2.1), was significantly associated with MetS. In the group without FHD, HBW (OR = 1.730; 95% CI = 1.1-2.7), but not LBW (OR = 1.139; 95% CI = 0.7-23), was associated with MetS. In the group with FHD, both LBW (OR = 2.690; 95% CI = 1.4-15.1) and HBW (OR = 3.289; 95% CI = 1.3-30.6) were associated with MetS. Both LBW (OR = 4.710; 95% CI = 1.4-39.7) and HBW (OR = 3.127; 95% CI = 1.3-45.1) were associated with MetS in children and adolescents with FHD in the maternal branch but not in the paternal branch. CONCLUSIONS HBW or LBW, in combination with positive FHD in the maternal branch, are determinants of MetS.

Abstract
Intrauterine growth retardation (IUGR) has been linked to development of type 2 diabetes in adulthood. Using a rat model, we tested the hypothesis that uteroplacental insufficiency disrupts the function of the electron transport chain in the fetal beta-cell and leads to a debilitating cascade of events. The net result is progressive loss of beta-cell function and eventual development of type 2 diabetes in the adult. Studies in the IUGR rat demonstrate that an abnormal intrauterine environment induces epigenetic modifications of key genes regulating beta-cell development; experiments directly link chromatin remodeling with suppression of transcription. Future research will be directed at elucidating the mechanisms underlying epigenetic modifications in offspring.

Abstract
OBJECTIVES To assess published evidences of the effect of birth weight on metabolic syndrome in adults. METHODS PubMed and LILACS databases were searched for articles published from 1966 through May 2006. The terms used were: "birth weight", "birthweight", "intra-uterine growth restriction (IUGR)", "fetal growth retardation", "metabolic syndrome", "syndrome X", "Reaven's X syndrome". Two hundred and twenty-four studies reporting estimates of the association between birth weight and metabolic syndrome or its components were considered eligible. Eleven studies provided odds ratios and were included in the meta-analysis. RESULTS All but two studies reported an inverse relationship between birth weight and metabolic syndrome. A comparison between low birth weight vs. normal birth weight subjects showed the random effects odds ratio for metabolic syndrome was 2.53 (95% CI: 1.57;4.08). The funnel plot graphic suggests a publication bias but, even in the studies with more than 400 subjects, the results remained significant (pooled odds ratio: 2.37 (95% CI: 1.15;4.90). CONCLUSIONS Low birth weight increases the risk of metabolic syndrome in adults.

Abstract
Over the last 15 years, a number of long-term health risks associated with reduced fetal growth have been identified, including cardiovascular diseases, hypertension, dyslipidaemia and type 2 diabetes. A common feature of these conditions is insulin resistance, which is thought to play a pathogenic role. However, despite abundant data in the literature, it is still difficult to trace the pathway by which fetal events, environmental or not, may lead to increased morbidity later in life. To explain this association, several hypotheses have been proposed pointing to the role of a detrimental fetal environment, a genetic susceptibility or an interaction between the two, and of the particular dynamic changes in adiposity that occur during catch-up growth. The relative impact of early postnatal events in relation to fetal growth has to be considered for designing health policy strategies for early interventions aimed at decreasing disease risk throughout life.

Abstract
PURPOSE OF REVIEW The alarming increase in the prevalence of pediatric obesity has led to a rise in associated metabolic complications in worldwide pediatric populations. This review summarizes recent literature on detection, pathophysiology, and potential intervention strategies for the metabolic derangements encountered in the overweight pediatric population. RECENT FINDINGS Development of metabolic complications associated with obesity during childhood track into adulthood and increase the risk for type 2 diabetes and early cardiovascular disease. Clustering of these metabolic abnormalities, which include insulin resistance, hypertension and dyslipidemia, constitutes the metabolic syndrome, which may affect up to 50% of overweight adolescents. Other serious disorders associated with obesity and insulin resistance include polycystic ovary disease and fatty liver. Family and school-based programs focusing on lifestyle modifications, as well as pharmacotherapy, have shown preliminary promise in reversing some of these derangements. SUMMARY As the trend in pediatric obesity continues to rise, providers must effectively identify children at risk for metabolic disturbances and implement long-lasting, successful treatment regimens. Continued research into the predecessors of cardiovascular disease that begin during childhood and how they can be altered is crucial to the future health of our pediatric population.

Abstract
Restricted growth before birth is associated with impaired insulin secretion but with initially enhanced insulin sensitivity in early postnatal life, which then progresses to insulin resistance and impaired glucose homeostasis by adulthood. This suggests that prenatal restraint impairs insulin secretion, but increases insulin sensitivity, before birth. Poor placental growth and function are major causes of restricted fetal growth in humans. We have therefore investigated the effects of restricted placental growth and function on plasma glucose, alpha-amino nitrogen and insulin concentrations and glucose- and arginine-stimulated insulin secretion in the fetal sheep at 120 and 140 days gestational age, and on insulin sensitivity, measured by hyperinsulinaemic euglycaemic clamp, at 130 days gestational age. Placental restriction decreased fetal blood pH and oxygen content, and weight in late gestation by approximately 20%. Reduced fetal and placental weights and indices of poor placental function, in particular fetal hypoxia and hypoglycaemia, were associated with impaired glucose- and arginine-stimulated insulin secretion, but not with changes in insulin sensitivity in the fetal sheep. We conclude that the impaired insulin secretion capacity reported in children and adults after intrauterine growth restriction, and in the neonatal and young adult sheep which is small at birth, is present in utero and persists. Whether this reflects the actions of the adverse intrauterine environment or changes to intrinsic capacity is unclear, but in utero interventions may be necessary to improve postnatal insulin secretion in the infant who is growth-restricted before birth.

OBJECTIVE Childhood obesity has become prevalent, resulting in a greater risk of hypertension, diabetes, and dyslipidemia. However, the relationship between these comorbid conditions and birth weight remains uncertain. We conducted this study to evaluate the relationship between birth weight and cardiovascular risk factors in children and adolescents. RESEARCH METHODS AND PROCEDURES In a nationwide survey conducted between 1992 and 2000, all schoolchildren 6 to 18 years old with glucosuria, proteinuria, or microscopic hematuria in repeated urine samples were included and received a physical examination and blood test. Those with gestational age <37 weeks were excluded. We enrolled 81,538 children (51,111 girls and 30,427 boys) and obtained their birth weights from the Taiwan Birth Registry. Obesity and hypertension were defined by age- and sex-specific cut-offs. Diabetes was diagnosed if the fasting glucose was >7 mM. RESULTS The risk of obesity was higher for those with birth weights > or =4000 grams [odds ratio (OR), 1.65] and 3543 to 3999 grams (OR, 1.28) and lower for those with birth weights 2601 to 2999 grams (OR, 0.90), using 3000 to 3542 grams as the reference group. An increased risk of diabetes was associated with both higher and lower birth weights, indicating a U-shaped relationship (OR, <2600 grams, 1.607; 2601 to 2999 grams, 1.119; 3543 to 3999 grams, 1.112; > or =4000 grams, 1.661). In the 10- to 12-year-old age group, the risk of hypertension was higher in those with birth weights <2600 grams (OR, 1.20). DISCUSSION Low birth weight was associated with childhood diabetes. High birth weight was correlated with childhood obesity and diabetes. Our data indicate different relationships between birth weight and the development of obesity, hypertension, and diabetes in childhood.

Abstract
OBJECTIVE The objective of this study was to investigate possible alterations in circulating levels of the adipocytokine visfatin in intrauterine growth-restricted and normal pregnancies, given that these groups differ considerably in fetal nutrition, body fat mass, and metabolic/endocrine mechanisms. METHODS Serum visfatin levels were prospectively measured by enzyme immunoassay in 40 mothers and their 40 singleton term fetuses and neonates on postnatal days 1 and 4. Twenty neonates had intrauterine growth restriction (birth weight < or = 3rd customized centile, adjusted for parameters that influence growth potential), and 20 were appropriate for gestational age. RESULTS Circulating maternal visfatin levels were significantly elevated in pregnancies with intrauterine growth restriction compared with control pregnancies with appropriate-for-gestational-age infants and negatively correlated with customized centiles in the group with intrauterine growth restriction. Postnatal day-1 and -4 visfatin levels were significantly higher in neonates with intrauterine growth restriction compared with neonates who were appropriate for gestational age. Postnatal-day-1 prefeeding insulin levels were significantly lower in neonates with intrauterine growth restriction. CONCLUSIONS Pathologic conditions in pregnancy that lead to intrauterine growth restriction could be responsible for elevated maternal visfatin levels. Higher visfatin levels in neonates with intrauterine growth restriction may serve as an early marker with prognostic value for later development of insulin resistance or type 2 diabetes, whereas lower insulin levels may indicate reduced beta-cell mass and/or impaired beta-cell function.

Abstract
One of the major public health challenges of the 21st century is type 2 diabetes. WHO estimates that by 2025 as many as 200-300 million people worldwide will have developed the disease. A distressing increase in children is perhaps the most alarming sign of something going wrong. Roughly half of the risk of type 2 diabetes can be attributed to environmental exposure and the other half to genetics. Central themes for prevention are the risk factors overweight, sedentary lifestyle, certain dietary components and perinatal factors. Overweight is the most critical risk factor, and should be targeted for prevention of type 2 diabetes especially among children and youths. Ethnicity and perinatal factors are also worth considering. Today we know that prevention helps. In the US Diabetes Prevention Programme for high risk individuals, there was a 58% relative reduction in the progression to diabetes in the lifestyle group compared with the controls. Within the lifestyle group, 50% achieved the goal of more than 7% weight reduction, and 74% maintained at least 150 min of moderately intense activity each week. This review discusses different forms of prevention, and proposes first of all to target people with Impaired Glucose Tolerance with increasing activity and altering dietary factors. And secondly, population-based measures to encourage increased physical activity and decreased consumption of energy-dense foods are important, and may target school children and young people, certain ethnic groups and women with gestational diabetes.

Abstract
Intrauterine growth retardation (IUGR) has been linked to later development of type 2 diabetes in adulthood. Human studies indicate that individuals who were growth retarded at birth have impaired insulin secretion and insulin resistance. Multiple animal models of IUGR demonstrate impaired beta-cell function and development. We have developed a model of IUGR in the rat that leads to diabetes in adulthood with the salient features of most forms of type 2 diabetes in the human: progressive defects in insulin secretion and insulin action prior to the onset of overt hyperglycemia. Decreased beta-cell proliferation leads to a progressive decline in beta-cell mass. Using this model, we have tested the hypothesis that uteroplacental insufficiency disrupts the function of the electron transport chain in the fetal beta-cell and leads to a debilitating cascade of events: increased production of reactive oxygen species, which in turn damage mitochondrial (mt) mtDNA and causes further production of reactive oxygen species (ROS). The net result is progressive loss of beta-cell function and eventual development of type 2 diabetes in the adult. Studies in the IUGR rat also demonstrate that an abnormal intrauterine environment induces epigenetic modifications of key genes regulating beta-cell development; experiments directly link chromatin remodeling with suppression of transcription. Future research will be directed at elucidating the mechanisms underlying epigenetic modifications in offspring.

Abstract
BACKGROUND Low birthweight (LBW) is associated with an increased risk for atherosclerotic coronary heart disease (ACHD) later in life. However, little information is currently available on the relationship between birthweight (BW) and risk factors for ACHD in children. METHODS The relationship between BW and risk factors for ACHD was evaluated in 330 Japanese children (187 boys and 143 girls) aged between 7 and 12 years, who underwent screening for lifestyle-related diseases in Okinawa, Japan. Routine chemical methods were used to determine the serum concentrations of lipids, apolipoproteins, uric acid and glucose. Serum insulin and adiponectin were measured by sandwich enzyme-linked immunosorbent assay. RESULTS BW was significantly correlated with serum concentrations of adiponectin (r= 0.163, P= 0.003) and uric acid (r=-0.166. P= 0.003), but not with insulin, lipids or apolipoproteins. These correlations were still significant even after adjusting for age, gender and body mass index (BMI) percentile (BW and adiponectin, r= 0.239, P= 0.000; BW and uric acid, r=-0.247, P= 0.000). In addition, BW was correlated with high-density lipoprotein-cholesterol (HDL-C) only after adjusting for age, gender and BMI percentile (r= 0.117, P= 0.034). In a stepwise multiple regression analysis, BW was a significant predictive variable for adiponectin and uric acid. However, weight velocity (weight gain/year) was a stronger predictive variable than BW for both adiponectin and uric acid. BW was not a significant predictive variable for HDL-C. Adiponectin was the strongest predictive variable for HDL-C. CONCLUSION BW is related to serum concentrations of adiponectin and uric acid. However, weight velocity was a stronger determinant of serum adiponectin and uric acid levels than BW in Japanese schoolchildren. Thus, it may be important to control weight gain to prevent the development of ACHD in children, especially in children with LBW.

Abstract
OBJECTIVE Our goal was to identify developmental trajectories of overweight in children and to assess early life influences on these trajectories. RESEARCH METHODS AND PROCEDURES Participants consisted of 1739 white, black, and Hispanic children who were younger than 2 years at the first survey and were followed up to 12 years of age. Repeated measures of overweight, defined as BMI > or = 95th percentile, were used to identify overweight trajectories with a latent growth mixture modeling approach. RESULTS Three distinct overweight trajectories were identified: 1) early onset overweight (10.9%), 2) late onset overweight (5.2%), and 3) never overweight (83.9%). After adjustment for multiple potential risk factors, male gender [odds ratio (OR), 1.5; 95% confidence interval (CI), 1.0 to 2.2], black ethnicity (OR, 1.7; 95% CI, 1.1 to 2.6), maternal 25 < or = BMI < 30 kg/m2 (OR, 2.2; 95% CI, 1.3 to 3.7) or > or = 30 kg/m2 (OR, 5.1; 95% CI, 2.9 to 9.1), maternal weight gain during pregnancy > or = 20.43 kg (OR, 1.7; 95% CI, 1.0 to 2.9), and birth weight > or = 4000 g (OR, 2.0; 95% CI, 1.2 to 3.4) were associated with an increased risk of early onset overweight. These risk factors, except maternal weight gain, exerted similar effects on late onset overweight. In addition, maternal smoking (OR, 1.6; 95% CI, 0.8 to 3.1) and birth order > or = 3 (OR, 2.3; 95% CI, 1.0 to 5.2) were associated with an increased risk of late onset overweight only. Breastfeeding > or = 4 months was associated with a decreased risk of both early (OR, 0.7; 95% CI, 0.3 to 1.3) and late onset overweight (OR, 0.7; 95% CI, 0.3 to 1.7). DISCUSSION Two trajectories of overweight and one never overweight group were identified. Early life predictors may have a significant influence on the developmental trajectories of overweight in children.

Abstract
CONTEXT Reduced birth weight is associated with increased risk for the insulin resistance syndrome. Part of this risk is hypothesized to originate from intrauterine growth retardation. OBJECTIVE The aim of this study is to determine whether or not the components of the insulin resistance syndrome are associated with reduced fetal growth. DESIGN This was a case-control study. SETTING The study was conducted in Beijing, China. PARTICIPANTS Included in this study were 296 singleton neonates (177 males and 119 females), including 76 (37 preterm and 39 full-term newborns) classified as small for gestational age (SGA) and 220 who were appropriate for gestational age (AGA) (84 preterm and 136 full-term newborns). MAIN OUTCOME MEASURES The main outcome measures were postabsorptive glucose, insulin, and lipids levels on the third day after birth. RESULTS Both full-term and preterm SGA neonates had higher insulin concentrations (mean +/- SEM, 17.11 +/- 1.15 vs.6.80 +/- 0.62 microIU/ml in full-term, P < 0.01; 11.99 +/- 1.18 vs.8.37 +/- 0.78 microIU/ml in preterm, P = 0.03), insulin to glucose ratios (4.48 +/- 0.37 vs. 1.78 +/- 0.20 in full-term, P < 0.01; 3.28 +/- 0.38 vs. 2.30 +/- 0.26 in preterm, P = 0.03), triglycerides (2.29 +/- 0.23 vs.1.57 +/- 0.13 mmol/liter in full-term, P < 0.01; 2.27 +/- 0.16 vs. 1.34 +/- 0.11 mmol/liter in preterm, P < 0.01), total cholesterol (2.35 +/- 0.12 vs. 1.82 +/- 0.22 mmol/liter in full-term, P = 0.04; 2.57 +/- 0.22 vs. 1.95 +/- 0.15 mmol/liter in preterm, P = 0.02), and low-density lipoprotein cholesterol (2.11 +/- 0.58 vs. 1.24 +/- 0.61 mmol/liter in full-term, P = 0.01; 1.87 +/- 0.60 vs. 1.38 +/- 0.59 mmol/liter in preterm, P < 0.01) concentrations than did AGA neonates; however, they had similar glucose levels. Among AGA infants, insulin concentration, insulin to glucose ratios, and lipids levels did not significantly differ between full-term and preterm babies. CONCLUSIONS In this study, SGA neonates displayed profiles suggestive of lower insulin sensitivity and less favorable lipid metabolism in the early postnatal period.

Abstract
Growth, bone, and body composition were studied at prepuberty in former very low birth weight (VLBW) infants who received dexamethasone (DEX) for bronchopulmonary dysplasia (BPD) compared with VLBW infants without DEX and term-born infants (TERM) to identify early life risk factors for later low bone mass. Children (56 girls/63 boys, 5-10 y) previously studied in neonatal life were recruited into three groups: VLBW + DEX, VLBW - DEX, and TERM children. Anthropometry and whole body bone, fat, and lean mass were measured. At prepuberty, the average height and weight for VLBW + DEX group were significantly lower than that for VLBW - DEX and TERM. Both VLBW groups had lower bone mass even adjusted for height and lean mass than TERM children and lower lean mass both total and adjusted for height. Z-scores for whole body bone mineral content below -1.5 occurred in 27.9% of VLBW + DEX children. The key factors for low bone mass were earlier gestational age and having BPD with DEX in neonatal life. In former VLBW infants, growth and bone mass attainment before puberty can be predicted from early life variables. VLBW + DEX children may be protected from overweight, but are at risk for short stature and low bone mass.

Abstract
BACKGROUND Low birthweight has been associated with an increased risk of obesity, insulin resistance, and diabetes in adulthood. The aim of this study was to evaluate IGF-I, adiponectin, insulin levels, and body fat in small-for-gestational-age (SGA) infants at birth. METHODS We performed a transverse comparative study in SGA and appropriate-for-gestational-age (AGA) infants. The study was conducted at the Hospital of Gynecology and Obstetrics in Leon, Mexico. Weight, length, and percent of body fat were evaluated during the first 48 h of birth. Glucose, insulin, leptin, adiponectin, and IGF-I levels in cord blood were measured. RESULTS We studied 100 infants (50 SGA and 50 AGA). A history of diabetes in a second-degree relative was higher in SGA infants than in AGA infants (48.0 vs. 30.0%, respectively; p = 0.03). Glucose, adiponectin, insulin and IGF-I levels were similar between the groups. Leptin levels and percentage of body fat were lower in SGA than AGA (15.3 vs. 23.4 ng/mL; p = 0.003, 11.1 vs. 12.7%; p <0.001, respectively). Logistic regression analysis showed that length, percentage of body fat, and leptin levels were positively associated with birthweight. However, leptin levels were not independent of percentage of body fat. CONCLUSIONS Low body fat and leptin levels, but no evidence of increased metabolic risk at birth, were found in SGA infants.
