Abstract
Background An increasing body of evidence supports the view that both an adverse intrauterine milieu and rapid postnatal weight gain in children born small for gestational age (SGA) contribute towards the risk for the development of chronic diseases in adult life. Content The aim of this review was to identify and summarize the published evidence on metabolic and cardiovascular risk, as well as risk of impaired cardiac function, intellectual capacity, quality of life, pubertal development and bone strength among children born SGA. The review will then address whether growth hormone (GH) therapy, commonly prescribed to reduce the height deficit in children born SGA who do not catch up in height, increases or decreases these risks over time. Summary Overall, there are limited data in support of a modest beneficial effect of GH therapy on the adverse metabolic and cardiovascular risk observed in short children born SGA. Evidence to support a positive effect of GH on bone strength and psychosocial outcomes is less convincing. Outlook Further evaluation into the clinical relevance of any potential long-term benefits of GH therapy on metabolic and cardiovascular endpoints is warranted.

Abstract
Intrauterine growth restriction (IUGR) is linked to increased risk for chronic disease. Placental ischemia and insufficiency in the mother are implicated in predisposing IUGR offspring to metabolic dysfunction, including hypertension, insulin resistance, abnormalities in glucose homeostasis, and nonalcoholic fatty liver disease (NAFLD). It is unclear whether these metabolic disturbances contribute to the developmental origins of exaggerated cardiovascular-renal disease (CVRD) risk accompanying IUGR. IUGR impacts the pancreas, adipose tissue, and liver, which are hypothesized to program for hepatic insulin resistance and subsequent NAFLD. NAFLD is projected to become the major cause of chronic liver disease and contributor to uncontrolled type 2 diabetes mellitus, which is a leading cause of chronic kidney disease. While NAFLD is increased in experimental models of IUGR, lacking is a full comprehension of the mechanisms responsible for programming of NAFLD and whether this potentiates susceptibility to liver injury. The use of well-established and clinically relevant rodent models, which mimic the clinical characteristics of IUGR, metabolic disturbances, and increased blood pressure in the offspring, will permit investigation into mechanisms linking adverse influences during early life and later chronic health. The purpose of this review is to propose mechanisms, including those proinflammatory in nature, whereby IUGR exacerbates the pathogenesis of NAFLD and how these adverse programmed outcomes contribute to exaggerated CVRD risk. Understanding the etiology of the developmental origins of chronic disease will allow investigators to uncover treatment strategies to intervene in the mother and her offspring to halt the increasing prevalence of metabolic dysfunction and CVRD.

Abstract
Poor prenatal development, followed by rapid childhood growth, conveys greater cardiometabolic risk in later life. Microswine offspring exposed to perinatal maternal protein restriction [MPR; "low protein offspring" (LPO)] grow poorly in late-fetal/neonatal stages. After weaning to an ad libitum (AL) diet, LPO-AL exhibit accelerated growth and fat deposition rates with low adiponectin mRNA, despite low-normal body fat and small intra-abdominal adipocytes. We examined effects of caloric restriction (CR) on growth and metabolic status in LPO and normal protein offspring (NPO) randomized to AL or CR diets from weaning. CR transiently reduced growth in both LPO and NPO, delaying recovery in female LPO-CR. Over 7.5-12.5 weeks, linear growth rates in LPO-CR were slower than LPO-AL ( P < 0.001) but exceeded NPO-AL; body weight growth rates fell but were lower in LPO-CR versus NPO-CR. Linear acceleration ceased after 12 weeks. At 16 weeks, percent catch-up in LPO-CR was reduced versus LPO-AL ( P < 0.001). Plasma growth hormone was low in LPO ( P < 0.02). CR normalized fat deposition rate, yet adiponectin mRNA remained low in LPO-CR ( P < 0.001); plasma adiponectin was low in all LPO-AL and in female LPO-CR. Insulin sensitivity improved during CR. We conclude that in LPO: 1) CR delays onset of, but does not abolish, accelerated linear growth, despite low growth hormone; 2) CR yields stunting via delayed onset, plus a finite window for linear growth acceleration; 3) MPR lowers adiponectin mRNA independently of growth, adiposity, or adipocyte size; and 4) MPR reduces circulating adiponectin in LPO-AL and female LPO-CR, potentially enhancing cardiometabolic risk.

Abstract
BACKGROUND Being born as small for gestational age (SGA) has an increased risk of developing metabolic/cardiovascular disturbances in later life. The role of adiponectin in the metabolic disturbance in SGA children remained undefined. OBJECTIVE The aim of this study was to investigate the association between serum levels of adiponectin and insulin sensitivity as well as lipid profile in short children born SGA at prepubertal ages. PATIENTS AND METHODS Serum levels of adiponectin, fasting glucose, insulin, IGF-I, IGFBP-1, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), apolipoprotein A-I (ApoA-I) and Apo B were measured in 30 prepubertal short children born SGA. Insulin resistance (IR) and β-cell function were assessed using the method of homeostatic model (HOMA). Data were compared to those of 30 short appropriate for gestational age (AGA) children matched for age, gender, height and body mass index, and correlation analysis was performed. RESULTS Short SGA children had significantly higher levels of fasting insulin, HOMA-IR and HOMA-β but lower levels of adiponectin than short AGA controls. No significant differences in the level of IGFBP-1 and IGF-I were found between the two groups. Serum levels of TC, TG, Apo B and Apo B/ApoA-I ratio were significantly higher in SGA, with 33% of hypercholesteraemia and 23% of hyperglyceridaemia. Stepwise multiple regression analysis revealed that serum adiponectin level was negatively correlated with HOMA-IR and TG and was positively correlated with birthweight SDS in SGA children. CONCLUSIONS These findings suggest that low serum adiponectin levels are associated with reduced insulin sensitivity and unfavourable lipid profiles in short children born SGA at prepubertal ages.

Abstract
Adipose tissue (AT) dysfunction links obesity of any cause with cardiometabolic disease, but whether early-life nutritional deficiency can program adipocyte dysfunction independently of obesity is untested. In 3-5-month-old juvenile microswine offspring exposed to isocaloric perinatal maternal protein restriction (MPR) and exhibiting accelerated prepubertal fat accrual without obesity, we assessed markers of acquired obesity: adiponectin and tumor necrosis factor (TNF)-α messenger ribonucleic acid (mRNA) levels and adipocyte size in intra-abdominal (ABD-AT) and subcutaneous (SC-AT) adipose tissues. Plasma cortisol, leptin and insulin levels were measured in fetal, neonatal and juvenile offspring. In juvenile low-protein offspring (LPO), adipocyte size in ABD-AT was reduced 22% (P = 0.011 v. controls), whereas adipocyte size in SC-AT was increased in female LPO (P = 0.05) and normal in male LPO; yet, adiponectin mRNA in LPO was low in both sexes and in both depots (P < 0.001). Plasma leptin (P = 0.004) and cortisol (P < 0.05) were reduced only in neonatal LPO during MPR. In juveniles, correlations between % body fat and adiponectin mRNA, TNF-α mRNA or plasma leptin were significant in normal-protein offspring (NPO) but absent in LPO. Plasma glucose in juvenile LPO was increased in males but decreased in females (interaction, P = 0.023); plasma insulin levels and insulin sensitivity were unaffected. Findings support nutritional programming of adipocyte size and gene expression and subtly altered glucose homeostasis. Reduced adiponectin mRNA and adipokine dysregulation in juvenile LPO following accelerated growth occurred independently of obesity, adipocyte hypertrophy or inflammatory markers; thus, perinatal MPR and/or growth acceleration can alter adipocyte structure and disturb adipokine homeostasis in metabolically adverse patterns predictive of enhanced disease risk.

Adiponectin levels are reduced while markers of systemic inflammation and aortic remodelling are increased in intrauterine growth restricted mother-child couple. BIOMED RESEARCH INTERNATIONAL 2014; 2014:401595.

Abstract
AIM OF THE STUDY To investigate the relationships between the adipocytokine levels, markers of inflammation, and vascular remodelling in pregnancies complicated by intrauterine growth restriction (IUGR). MATERIALS AND METHODS This was a retrospective study. One hundred and forty pregnant patients were enrolled. Adiponectin, leptin, tumor necrosis factor α (TNFα), interleukin-6 (IL-6), and C reactive protein (CRP) were assessed in IUGR, small for gestational age (SGA), and appropriate for gestational age (AGA) mother-child couples at delivery. IUGR and SGA fetuses were defined as fetuses whose estimated fetal weight (EFW) was below 10th percentile for gestational age with and without umbilical artery (UA) Doppler abnormalities, respectively. Fetal aorta intima media thickness (aIMT) was evaluated by ultrasound in the same fetal groups. Data were analyzed by R (version 2.15.2). RESULTS There were 37 IUGR mother-child couples, 33 SGA, and 70 AGA. Leptin, TNFα, IL-6, and CRP serum levels were higher in IUGR pregnant patients (P < 0.05). Adiponectin levels were significantly reduced in IUGR fetuses compared to SGA and AGA, while leptin, TNFα, and IL-6 levels were higher in IUGR group (P ≤ 0.05). Fetal aIMT was significantly higher in IUGR (P < 0.05) and in this group there was a negative correlation between aIMT and adiponectin/leptin ratio (A/L ratio) (P < 0.05) and between adiponectin and IL-6 levels (P < 0.05). CONCLUSIONS In conclusion, compared to SGA and AGA, IUGR fetuses had reduced circulating levels of adiponectin and elevated measures of aIMT and several inflammatory markers. Moreover, adiponectin levels were negatively correlated with aIMT in IUGR fetuses suggesting a possible causal link between reduced adiponectin and vessel remodelling.

Abstract
BACKGROUND Small for gestational age (SGA) birth has been associated with adipocyte dysfunction during later phases of life. Because SGA women are at a higher risk of developing polycystic ovary syndrome (PCOS), adipocyte dysfunction detected in patients with PCOS may be associated with SGA birth. AIMS To determine whether SGA birth is related to altered serum markers of adipose tissue dysfunction during the third decade of life in Brazilian women. A secondary objective was to relate the presence of PCOS with serum markers of adipose tissue dysfunction. STUDY DESIGN Prospective cohort observational study. SUBJECTS A total of 384 women born at 37 to 42weeks of gestation from June 1, 1978 to May 31, 1979 in Ribeirão Preto, State of São Paulo, Brazil. After exclusion, 165 women participated in the study. Of these women, 43 were in the SGA group and 122 were in the adequate for gestational age group based on birth weight determined from cohort files. OUTCOME MEASURES Body mass index (BMI), arterial systolic and diastolic pressures, abdominal circumference and serum concentrations of total testosterone, fasting glucose and insulin, lipid profile, adiponectin, leptin and necrosis factor alpha tumor (TNFα). RESULTS BMI was an independent predictor of lower adiponectin (adjusted coefficient=-0.02, p=0.01) and higher leptin (adjusted coefficient=0.06, p=0.01) concentrations. The serum insulin concentration was associated with higher leptin (adjusted coefficient=0.03, p=0.02) and TNF-α (adjusted coefficient=0.01, p=0.03) concentrations. Having PCOS or being born SGA did not predict any markers of adipocyte dysfunction.

Abstract
OBJECTIVE To explore the long-term impact of intrauterine growth restriction (IUGR) among a diverse, contemporary cohort of U.S. children. DESIGN AND METHODS A retrospective cohort of 42 children exposed to IUGR and 464 unexposed who were members of Kaiser Permanente of Colorado. Height and weight measurements since birth and measures of abdominal adiposity and insulin-resistance were measured at an average age of 10.6 (±1.3) years. RESULTS Infants born IUGR experienced "catch-up growth" in the first 12 months of life at a rate of 3.58 kg/m² compared to 2.36 kg/m² in unexposed infants (P = 0.01). However, after 1 year of age, no differences in BMI growth velocity were observed. Nevertheless children exposed to IUGR had higher waist circumference (67.0 vs. 65.3 cm, P = 0.03), higher insulin (15.2 vs. 11.0 μU/ml, P = 0.0002), higher HOMA-IR (2.8 vs. 2.3, P = 0.03), and lower adiponectin levels (9.0 vs. 12.0 μg/ml, P = 0.003) in adolescence, independent of other childhood and maternal factors. CONCLUSIONS Our data from a contemporary US cohort suggests that children exposed to IUGR have increased abdominal fat and increased insulin resistance biomarkers despite no differences in BMI growth patterns beyond 12 months of age. These data provide further support for the fetal programming hypothesis.

Abstract
In girls, low birth weight (LBW), when followed by postnatal catch-up growth, is accompanied by endocrine-metabolic abnormalities which include a more adipose body composition (with increased visceral fat), insulin resistance and a less favorable adipokine profile as early as in the pre-school age. These girls also exhibit follicle-stimulating hormone hypersecretion both in early infancy and early post-menarche, with reduced uterine and ovarian size in adolescence. These endocrine and gynecological changes result in a decreased ovulation rate and in an advanced tempo of adrenarche, pubertal development and menarche (by nearly a year, compared to non-LBW girls). The earlier maturation in LBW girls may result in a loss of about 1 SD in height, as compared with target height. During the post-menarcheal period, LBW girls are at increased risk of developing polycystic ovary syndrome. Early insulin sensitization may prevent or delay some of the endocrine-metabolic abnormalities associated to LBW.

Abstract
OBJECTIVE To investigate whether maternal serum levels of adiponectin in the first trimester are altered in pregnancies that subsequently deliver small for gestational age (SGA) neonates. METHODS Maternal serum adiponectin and pregnancy-associated plasma protein A (PAPP-A) were measured at 11-13 weeks' gestation in 50 singleton normotensive pregnancies that delivered SGA neonates and 300 non-SGA controls. The median adiponectin and PAPP-A levels in the SGA and non-SGA groups, expressed as multiple of the unaffected median (MoM), were compared. RESULTS The distribution of serum adiponectin was made gaussian by square root (sqrt) transformation. Regression analysis in the non-SGA group demonstrated that for sqrt adiponectin a significant independent contribution was provided by maternal age, weight, smoking status, African and South-Asian racial origin. Each value in the SGA and non-SGA group was then converted into a multiple of the non-SGA median (MoM) after adjustment for maternal characteristics. In the SGA group, compared to the non-SGA controls, median maternal serum PAPP-A was decreased (0.79, interquartile range [IQR] 0.54-1.06 MoM vs. 1.00, IQR 0.71-1.39 MoM) but adiponectin MoM was not significantly different (0.89, IQR 0.65-1.31 MoM vs. 1.02, IQR 0.70-1.29 MoM). CONCLUSION Maternal serum adiponectin is not a useful biochemical marker for early prediction of SGA.

Abstract
The association between premature pubarche (PP) and metabolic syndrome is controversial and not supported by some authors. The aim of this study was to determine insulin resistance syndrome, plasma adiponectin, and fatty acid profile in PP girls to discern potential confounder variables and markers of metabolic disturbances. We studied 22 prepubertal girls with a diagnosis of PP and 20 healthy controls who differed in body mass index (BMI) (19.33 +/- 0.71 vs 17.30 +/- 0.60). We evaluated insulin resistance syndrome components and postprandial response of adiponectin, nonesterified fatty acids, and fatty acid profile after consumption of a standardized breakfast. No lipid disturbances were detected in the PP group. High-density lipoprotein to low-density lipoprotein cholesterol ratio tended to be lower in PP girls (P = .052), but this effect disappeared when data were adjusted for both BMI and age (P = .480). Insulin levels tended to be higher at 2 hours in PP girls, who showed significantly higher C-peptide area under the curve. In contrast, adiponectin at 3 hours after the meal and postprandial adiponectin area under the curve were significantly lower. The PP girls showed significantly higher percentages of eicosapentaenoic acid in total plasma and plasma phospholipids. No differences were found in the postprandial fatty acid clearance rate. In conclusion, PP girls and controls differed in postprandial plasma adiponectin response and in postprandial plasma C-peptide response after both BMI and age adjustment. Cholesterol plasma disturbances were mainly attributable to their higher BMI, although n-3 polyunsaturated fatty acids were higher because of the PP.

Abstract
Children born small for gestational age (SGA) are prone to developing obesity, insulin resistance and type 2 diabetes. Adiponectin and leptin are adipocytokines associated with insulin sensitivity parameters. We aimed to relate serum adiponectin and leptin levels with insulin sensitivity parameters in prepuberal SGA children with and without catch-up growth (SGA+CUG; SGA-CUG, respectively) and to analyze the usefulness of these adipocytokines as early markers of insulin resistance. We analysed adiponectin, proinsulin, leptin, growth factors, insulin, HOMA IR and HOMA beta(cell) in 23 SGA+CUG, 26 SGA-CUG children compared with 48 prepuberal appropiate for gestational age (AGA). SGA children had adiponectin levels comparable to AGA children. Leptin levels were different between sexes, showed to be higher in SGA+CUG group (p=0.040) and these were significantly correlated with insulin sensitivity parameters. These results suggest leptin resistance as an adaptive mechanism to increase energy balance, but an altered functional response of adipocytes cannot be discarded.

Abstract
Intrauterine growth restriction (IUGR) is a risk factor for cardiovascular disease, type 2 diabetes mellitus, and obesity in adulthood. Several studies on diverse geographic and ethnic cohorts have provided evidence that being born small for gestational age (SGA) increases adult disease risk through various pathways of metabolic dysregulation. Unfavorable influences in the fetal environment may program metabolic homeostasis in later life affecting blood pressure, glucose tolerance and lipid regulation. Fetal restricted protein supply may impair the development of the kidney and reduce the nephron number, which is involved in blood pressure regulation. Moreover, children exposed to IUGR may exhibit postnatal rapid catch-up growth, altered body composition, increased visceral adiposity and low adiponectin levels which predispose to cardiovascular disease and type 2 diabetes mellitus in adulthood. Impairment in fetal pancreatic development and subsequent insulin signalling deficits due to IUGR may also be involved in the pathogenesis of these conditions. This review summarizes some of the hypotheses that have been put forward to explain the association between fetal growth restriction and subsequent metabolic dysregulation that may increase adult disease risk.

Abstract
BACKGROUND Fetal glucocorticoid exposure is associated with later development of features of the metabolic syndrome such as central obesity and insulin resistance. Fat tissue, especially visceral fat, produces adiponectin, which is inversely associated with insulin resistance in older children and adults. Adipocytes also produce leptin, directly related to measures of adiposity. It is unknown how the secretion of these hormones in early childhood is related to pregnancy levels of CRH, a proxy of fetal glucocorticoid exposure. AIM Our aim was to study the relationship of maternal midpregnancy CRH levels with offspring levels of adiponectin and leptin in early childhood. METHODS The study population consisted of 349 mother-children pairs from Project Viva, a prospective prebirth cohort study from eastern Massachusetts. We created a general linear model with log CRH levels in midpregnancy maternal blood as the predictor and adiponectin and leptin measured in the 3-yr-old offspring as outcomes, adjusting for covariates. RESULTS The means (sd) of log CRH, adiponectin, and leptin were 4.97 (0.65) log pg/ml, 22.4 (5.8) microg/ml, and 1.9 (1.8) ng/ml. For each unit increment in log CRH, mean value of offspring adiponectin was 1.10 microg/ml (95% confidence interval = 0.06-2.14) higher. We found no association with leptin (-0.08 ng/ml; 95% confidence interval = -0.40-0.24). CONCLUSIONS Higher maternal blood levels of CRH were associated with higher levels of adiponectin but unchanged levels of leptin at age 3 yr. The increased adiponectin levels might represent secretion from organs other than fat or reflect a compensatory mechanism to increase insulin sensitivity.

Abstract
OBJECTIVE The aim of this study was to test whether being born small for gestational age (SGA) has an impact on adiponectin and leptin levels and the IGF system in relation to insulin sensitivity, taking into consideration the severity of growth restriction. RESEARCH DESIGN AND METHODS Serum levels of adiponectin, leptin, fasting glucose, fasting insulin (I(F)), the homeostasis model assessment insulin resistance index (HOMA-IR), IGF-1, free IGF-1, IGF-binding protein (IGFBP)-1 and -3, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides were evaluated in 57 children at age 4-10 years. Of these, 32 had been born appropriate size for gestational age (AGA) and 25 SGA (14 in the <3rd percentile and 11 in the 3rd-10th percentile). RESULTS; The SGA 3rd-10th percentile children were already insulin resistant at prepubertal age (I(F) 39.6 +/- 16.8 vs. 27 +/- 12 pmol/l, P < 0.01, and HOMA-IR 1.4 +/- 0.6 vs. 0.95 +/- 0.42 in SGA vs. AGA children, P < 0.05). Their IGF-1 and IGFBP-3 concentrations were significantly lower than those in AGA children (160.4 +/- 66.2 vs. 207 +/- 66.8 microg/l, P < 0.05 and 2.3 +/- 0.4 vs. 3.51 +/- 1.21 mg/l in SGA vs. AGA children, P < 0.01). The SGA <3rd percentile children had higher adiponectin (15.6 +/- 5.7 mg/l, P < 0.05) and IGFBP-1 levels (113.5 +/- 33.9 microg/l, P < 0.05) than AGA children (11.3 +/- 6.6 mg/l and 90.8 +/- 24.2 microg/l, respectively) and lower IGF-1 and IGFBP-3 concentrations (162.6 +/- 68.4 microg/l, P < 0.05 and 2.4 +/- 0.7 mg/l, P < 0.01). They also had significantly lower waist circumference (P < 0.05). Leptin levels did not differ among groups, but an inverse correlation with IGFBP-1 (r = -0.55, P < 0.01) was found in the pooled SGA group. CONCLUSIONS Intrauterine growth restriction appears to affect the IGF axis at prepubertal age, and its severity plays a role in insulin sensitivity.

Abstract
Intrauterine growth restriction (IUGR) is the failure of the fetus to achieve his/her intrinsic growth potential, due to anatomical and/or functional disorders and diseases in the feto-placental-maternal unit. IUGR results in significant perinatal and long-term complications, including the development of insulin resistance/metabolic syndrome in adulthood. The thrifty phenotype hypothesis holds that intrauterine malnutrition leads to an adaptive response that alters the fetal metabolic and hormonal milieu designed for intrauterine survival. This fetal programming predisposes to an increased susceptibility for chronic diseases. Although the mechanisms controlling intrauterine growth are poorly understood, adipose tissue may play an important role in linking poor fetal growth to the subsequent development of adult diseases. Adipose tissue secretes a number of hormones, called adipocytokines, important in modulating metabolism and recently involved in intrauterine growth. This review aims to summarize reported findings concerning the role of adipocytokines (leptin, adiponectin, ghrelin, tumor necrosis factor (TNF), interleukin-6 (IL6), visfatin, resistin, apelin) in early life, while attempting to speculate mechanisms through which differential regulation of adipocytokines in IUGR may influence the risk for development of chronic diseases in later life.

Abstract
Adipose tissue is involved in the regulation of glucose and lipid metabolism, energy balance, inflammation and immune response. Abdominal obesity plays a key role in the development of insulin resistance because of the high lipolytic rate of visceral adipose tissue and its secretion of adipocytokines. Low birth weight subjects are prone to central redistribution of adipose tissue and are at high risk of developing metabolic syndrome, type 2 diabetes and cardiovascular disease. Intrauterine adipogenesis may play a key role in the fetal origin of the pathogenesis of metabolic syndrome, type 2 diabetes and cardiovascular disease. Therefore, knowledge of the behavior of visceral adipose tissue-derived stem cells could provide a greater understanding of the metabolic risk related to intrauterine growth retardation, with potential clinical implications for the prevention of long-term metabolic alterations.

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 The aim of this study was to quantify serum adiponectin concentrations in short children born small for gestational age (SGA) compared with those in children born appropriate for gestational age (AGA), and to assess the relationship between the serum levels of adiponectin and insulin-like growth factor binding protein-1 (IGFBP-1) known as a predictor of the development of type 2 diabetes mellitus and cardiovascular disease. SUBJECTS AND METHODS Sixteen prepubertal short children born SGA and 20 short children born AGA, matched for age, body mass index, height, pubertal status, gestational age, bone age and midparental height, were included in the study. The serum levels of adiponectin, IGFBP-1, insulin and insulin-like growth factor-I (IGF-I) were measured in the fasting state. RESULTS The levels of serum adiponectin were significantly lower in the SGA than in AGA children (10.5 +/- 4.2 vs. 13.9 +/- 5.1 micro g/ml, P < 0.05). The levels of serum IGFBP-1, insulin and IGF-I were all similar in both groups. Overall, there was a significant positive correlation between adiponectin and IGFBP-1 (r = 0.40, P < 0.05). CONCLUSIONS Our results suggest that hypoadiponectinaemia in short SGA children without catch-up growth may reflect insulin resistance and imply a higher risk of developing type 2 diabetes mellitus. Additionally, adiponectin may be a more sensitive indicator for latent insulin resistance than IGFBP-1 in short SGA children.

Abstract
BACKGROUND Adiponectin and resistin are fat cell-derived hormones, which are thought to be respectively protective and disadvantageous with regard to the development of cardiovascular disease and diabetes mellitus type 2. Low birth weight has been associated with increased risks for the development of these diseases. In short, small-for-gestational-age (SGA) children, GH therapy has several positive effects regarding cardiovascular risk factors. On the other hand, concern has been expressed about the effects of GH therapy on insulin sensitivity. METHODS We measured adiponectin and resistin levels in 136 short prepubertal children born SGA and their association with cardiovascular risk parameters and growth factors. Also, we compared the levels with normal-statured controls. The effect of GH treatment was evaluated in 50 short SGA children vs. baseline and vs. an untreated sex- and age-matched SGA control group. RESULTS Short SGA children had similar adiponectin and lower resistin levels, compared with normal-statured controls. In GH-treated SGA children, neither adiponectin nor resistin levels changed significantly during 2 yr of GH treatment. Compared with untreated sex- and age-matched SGA controls, GH-treated SGA children had similar adiponectin and lower resistin levels. Adiponectin correlated inversely with age but not any cardiovascular risk parameter or growth factor. Higher IGF-I levels in GH-treated children were associated with lower resistin levels. CONCLUSIONS Compared with normal-statured controls, short prepubertal SGA children had similar adiponectin and lower resistin levels. Two years of GH treatment had no effect on their adiponectin and resistin levels.

Abstract
Hypoxia is a common neonatal stress that induces insulin resistance and a decrease in body weight gain. Dexamethasone is often used to treat neonatal cardiopulmonary disease, and also leads to insulin resistance and a decrease in body weight gain. The current study addressed the hypothesis that serum concentrations of the adipokines adiponectin and/or resistin are altered during hypoxia and/or dexamethasone therapy in neonatal rats. Rat pups with their lactating dams were exposed to hypoxia (11% O2) from birth and treated with a tapering regimen of dexamethasone from postnatal day (PD) 3-6. Serum adiponectin and resistin were measured on PD7. Hypoxia and dexamethasone independently decreased body weight gain and increased adiponectin levels. The combination of hypoxia and dexamethasone did not further increase adiponectin. Dexamethasone caused a small increase in resistin in normoxic pups, which may facilitate the hyperinsulemic- normoglycemic state we previously described. We also conclude that adiponectin is increased during hypoxia in response to a decrease in the sensitivity to insulin.

Abstract
Children born small for gestational age are at high risk of developing insulin resistance, type 2 diabetes, hyperlipidemia, hypertension and cardiovascular disease in adulthood. In addition, approximately 10% of SGA children do not achieve a normal adult height. Studies performed in SGA children to evaluate markers of metabolic disease in prepubertal, pubertal and adolescent subjects, indicate a higher prevalence of subtle endocrine and metabolic abnormalities that may precede the onset of overt disease in adulthood. At present, however, there are no conclusive data supporting the need of systematic close monitoring of GH-IGF, hypothalamus-pituitary-adrenal and hypothalamus-pituitary-gonadal axes, as well as insulin sensitivity, glucose homeostasis, and lipid metabolism. Monitoring of metabolic parameters should probably be reserved to SGA children with genetic predisposition to type 2 diabetes and hyperlipidemia, as early identification of metabolic alterations might prompt effective preventive interventions and, ultimately, reduce cardiovascular risk.
