ABSTRACT
Purpose: To explore the relationships between serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP) levels and glucolipid metabolism disorders (GLMD) in obese children and adolescents. Patients and Methods: In this cross-sectional study, 105 obese children and adolescents were selected for the detection of TNF-α, IL-6, hs-CRP, and glycolipid metabolism indicators. All participants were divided into elevated TNF-α group (≥8.1 pg/mL; n=49) and normal TNF-α group (<8.1 pg/mL; n=56), elevated IL-6 group (≥5.9 pg/mL; n=13) and normal IL-6 group (<5.9 pg/mL; n=92), elevated hs-CRP group (≥3.0 mg/L; n=44) and normal hs-CRP group (<3.0 mg/L; n=61), respectively. Results: Low-density lipoprotein cholesterol (LDL-C) in the elevated TNF-α group was higher than that in the normal TNF-α group (P=0.010). TNF-α was positively correlated with LDL-C (P=0.005). Fasting insulin (FINS) and homeostasis model assessment of insulin resistance (HOMA-IR) in the elevated IL-6 group were higher than those in the normal IL-6 group (all for P <0.05), while high-density lipoprotein cholesterol (HDL-C) in the elevated IL-6 group was lower than that in the normal IL-6 group (P<0.001). IL-6 was positively correlated with FINS, 2-hour postprandial insulin, HOMA-IR and triglyceride (all for P <0.01), while was negatively correlated with HDL-C (P=0.006). Moreover, hs-CRP was positively correlated with FINS and HOMA-IR (all for P <0.05). Conclusion: There may be correlations between serum TNF-α, IL-6, hs-CRP levels and GLMD in obese children and adolescents. Attention should be paid to monitoring serum inflammatory factors and preventing their elevation in obese children and adolescents, thus reducing the occurrence of GLMD.
ABSTRACT
BACKGROUND: Good quality of care for inflammatory bowel disease (IBD) depends on high-standard management and facility in the IBD center. Yet, there are no clear measures or criteria for evaluating pediatric IBD (PIBD) center in China. The aim of this study was to develop a comprehensive set of quality indicators (QIs) for evaluating PIBD center in China. METHODS: A modified Delphi consensus-based approach was used to identify a set of QIs of structure, process, and outcomes for defining the criteria. The process included an exhaustive search using complementary approaches to identify potential QIs, and two web-based voting rounds to select the QIs defining the criteria for PIBD center. RESULTS: A total of 101 QIs (35 structures, 48 processes and 18 outcomes) were included in this consensus. Structure QIs focused on the composition of multidisciplinary team, facilities and services that PIBD center should provide. Process QIs highlight core requirements in diagnosing, evaluating, treating PIBD, and disease follow-up. Outcome QIs mainly included criteria evaluating effectiveness of various interventions in PIBD centers. CONCLUSION: The present Delphi consensus developed a set of main QIs that may be useful for managing a PIBD center. Video Abstract.

BACKGROUND: Current adult studies suggest that uric acid (UA) is associated with body fat, but the relationship in obese children is unclear. Thus, we aim to evaluate the association between uric acid and body composition of obese children. METHODS: A total of 79 obese children were included in this study, and 52 children (34 boys and 18 girls) underwent a 6-week weight loss camp, including 34 boys and 18 girls. Six-week weight-loss interventions were performed on all participants through aerobic exercise and appropriate dietary control. Laboratory tests and body composition were collected before and after the intervention. RESULTS: Before the intervention, correlation analysis demonstrated that uric acid was positively correlated with height, weight, body mass index (BMI), waist circumference, hip circumference, fat mass (FM), and free fat mass (FFM) with adjusting for age and gender (P < 0.05). After 6 weeks of intervention, the participants gained 3.12 ± 0.85 cm in height, body fat percentage decreased by 7.23 ± 1.97%, and lost 10.30 ± 2.83 kg in weight. Univariate and multivariate analysis indicated that uric acid at baseline was associated with FM reduction during weight loss (P < 0.05). CONCLUSIONS: This study is the first report that uric acid is associated with BMI and FM, and may play an important role in the reduction of FM during weight loss in obese children and adolescents. The interaction between UA and adiposity factors and its underlying mechanisms need to be further explored. TRIAL REGISTRATION: This study was registered in Clinical Trials.gov (NCT03490448) and approved by the Ethics Committee of Xinhua Hospital, Shanghai Jiao Tong University School of Medicine.
ABSTRACT
INTRODUCTION AND AIMS: Choline-metabolizing genetic variation may interact with choline intake on fetal programming and pregnancy outcome. This case-control study aims to explore the association of maternal choline consumption and phosphatidylethanolamine N-methyltransferase (PEMT) gene polymorphism rs7946 with preterm birth risk. METHODS: 145 Han Chinese women with preterm delivery and 157 Han Chinese women with term delivery were recruited in Shanghai. Dietary choline intake during pregnancy was assessed using a validated food frequency questionnaire. Additionally, DNA samples were genotyped for PEMT rs7946 (G5465A) with plasma homocysteine (Hcy) levels measured. RESULTS: Compared with the lowest quartile of choline intake, women within the highest consumption quartile had adjusted odds ratio (aOR) for preterm birth of 0.48 (95% confidence interval, CI [0.24, 0.95]). There was a significant interaction between maternal choline intake and PEMT rs7946 (p for interaction = 0.04), where the AA genotype carriers who consumed the energy-adjusted choline <255.01 mg/day had aOR for preterm birth of 3.75 (95% CI [1.24, 11.35]), compared to those with GG genotype and choline intake >255.01 mg/day during pregnancy. Additionally, the greatest elevated plasma Hcy was found in the cases with AA genotype and choline consumption <255.01 mg/day (p < 0.001). CONCLUSION: The AA genotype of PEMT rs7946 may be associated with increased preterm birth in these Han Chinese women with low choline intake during pregnancy.

BACKGROUND: The pathogenesis of parenteral nutrition (PN)-associated liver dysfunction is multifactorial. Lipid emulsions may be one of the putative mechanisms. Our aim was to comparatively assess the effect of parenteral olive oil- and soybean oil-based lipid emulsions on liver chemistry and bile acid composition in preterm infants. METHODS: We performed a double-blind, randomized clinical study in which 103 preterm infants were randomly assigned to PN using either soybean oil-based lipid emulsion (SO; n = 51) or olive oil (OO)-based lipid emulsion (OO; n = 52). The primary end point was liver chemistry. The secondary end point was the plasma bile acid composition. RESULTS: One hundred infants completed this study. In the SO group, the serum direct bilirubin was significantly higher after PN for 7 days compared with the OO group. Bile acids increased over time in both treatment groups. However, specific differences in the change in bile acid composition over time were noted between groups. CONCLUSIONS: Differences in direct bilirubin and bile acid composition were observed over time between the 2 groups. Considering the long-term use of lipid emulsions in higher risk babies, these findings might be useful for understanding the pathogenesis of PN-associated liver dysfunction.

BACKGROUND & AIMS: Olive oil (OO), medium-chain triglycerides (MCT)/long-chain triglycerides (LCT) mixture and soybean oil (SO) lipid emulsions are currently used for preterm infants in China. The aim of our study was to compare the lipid profile, fatty acid composition, and antioxidant capacity of preterm infants administered OO, MCT/LCT, or SO lipid emulsions. METHODS: In this study, 156 preterm infants (birth weight < 2000 g and gestational age < 37 weeks) received parenteral nutrition (PN) containing OO, MCT/LCT, or SO lipid emulsions for a minimum of 14 d. On days 0, 7, and 14, the lipid profile, fatty acid composition and antioxidant capacity were analyzed. RESULTS: On day 7, HDL levels in the MCT/LCT group were significantly lower than in the OO (1.06 ± 0.40 mmol/L) or SO groups. LDL levels were higher in the OO group than in the MCT/LCT or SO groups on day 7. A-I/B was higher in MCT/LCT than in OO or SO groups. Myristic acid (C14:0) levels on days 7 and 14 increased in MCT/LCT compared to the OO and SO groups. The OO group had higher oleic acid (C18:1n9) levels than the two other groups. Linoleic acid (C18:2n6), linolenic acid (C18:3n3), and eicosapentaenoic acid (20:5n3) were significantly lower in the OO group than in MCT/LCT or SO groups. Monounsaturated fatty acid levels decreased, and ω-6 polyunsaturated fatty acid and essential fatty acids levels increased in MCT/LCT and SO groups. No significant differences were obtained in SOD, MDA, GSH-Px, and T-AOC among the groups. CONCLUSION: The three lipid emulsions were safe and well tolerated in preterm infants. Oleic acid (C18:1n9) levels increased and LA (C18:2n6), ALA (C18:3n3), and EPA (C20:5n23) levels decreased in OO compared to MCT/LCT or SO.

Overweight and obesity may contribute to bone fractures in children; however, the mechanism involved is not clear. In this study, we assessed the relation between serum osteocalcin levels and body composition in obese children. A total of 79 children (ages 7-12 years) were recruited. Serum osteocalcin levels were negatively correlated with fat percentage and visceral fat area (râ=â-0.24 and râ=â-0.46, respectively, Pâ<â0.05); however, no statistically significant association was found between obesity degree and serum osteocalcin levels (râ=â-0.29, Pâ=â0.052). Serum osteocalcin levels were positively correlated with lean body mass, fat-free mass, and fat-free mass index (râ=â0.24, 0.23, and 0.31, respectively; Pâ<â0.05). In addition, serum osteocalcin levels were significantly lower in severely obese (44.46â±â9.73 µg/mL) and moderately obese (48.72â±â10.82 µg/mL) children than in mildly obese (55.43â±â12.4 µg/mL) and overweight (54.36â±â11.96 µg/mL) children (Pâ=â0.02). These findings indicate that body composition is related to serum osteocalcin levels in overweight and obese children.

OBJECTIVE: The aim of study was to confirm the protective effects of parenteral glutamine supplementation on liver injury in premature infants and determine how quickly effects became evident. METHODS: We performed a double-blind, randomized, controlled clinical study to assess the effect of parenteral nutrition (PN) supplemented with glutamine in premature infants. Thirty infants from two children's centers, were randomly assigned to either a control group (Standard PN; n=15) or a glutamine-supplemented group (GlnPN; n=15). The primary endpoint was hepatic function. The secondary endpoints were total duration of PN, weight and head circumference gain, length of hospitalization, and days on a ventilator. RESULTS: The serum level of alkaline phosphatase (AKP) after parenteral nutrition for 14 days was significantly higher (p<0.05) in the control group. But in the glutamine-supplemented group, the serum concentration of aspartate aminotransferase (AST) and gamma glutamyltransferase (GGT) significantly decreased after PN for 7 days and 14 days (p<0.05), and the level of alkaline phosphatase (AKP) showed no increase. The levels of AKP and GGT were significantly different with time by group interaction. Levels of AKP was higher in control group than glutamine-supplemented group, and GGT level was lower in glutamine-supplemented group compared with controls. There were no significant differences between the groups in terms of total duration of PN, weight gain (g/d), increase in head circumference (cm/w), length of hospitalization, and duration of mechanical ventilation. CONCLUSION: The longer the duration of parenteral nutrition, the more severe hepatic dysfunction became. Parenteral glutamine supplementation suggested a hepatoprotective effect.

BACKGROUND: primary intestinal lymphangiectasia (PIL) is a rare digestive disease and few studies have focused on the therapeutic effect in PIL patients. This study was undertaken to evaluate nutrition-oriented intervention in children with PIL. METHODS: four children with PIL were studied. Their medical records were reviewed. Anthropometric measurements and blood tests were performed during a 8-18 month follow-up. RESULTS: during hospitalization, the 4 patients were subjected to diet intervention. Parenteral nutrition (PN) support was also given to 3 of them. Clinical symptoms and laboratory parameters of the patients were significantly improved at discharge. After discharge, the patients continued diet control, 2 of whom received intermittent PN support. The mean follow-up duration of the 4 patients was 13 months (range, 8-18 months) and they all kept in a stable condition without symptoms relapse. Weight, height and body mass index for age were normal during the follow-up, while total protein, albumin and immunoglobulin concentrations were still slightly below normal level. CONCLUSIONS: nutrition therapy is effective as a valid and safe therapeutic management for PIL patients. No growth retardation was observed in the 4 children after the therapy, but they are still at risk of nutrient malabsorption. Therefore, they need long-term, regular monitoring and intensive nutritional care.

The aim of the study was to evaluate the impact of carbohydrate-to-fat ratio on body weight and appetite regulation in Wistar rats. Twenty-four Wistar rats were randomized to three dietary groups (n = 8): normal carbohydrate diet (NC), low-carbohydrate diet (LC) and high-carbohydrate diet (HC) for 12 weeks. Body weight and food intake were recorded. Circulating leptin and insulin levels were measured by radioimmunoassay method. The expression levels of leptin receptor, insulin receptor, orexin, neuropeptide Y (NPY), agouti-related protein (AgRP) and melanocortin-4 receptor (MC-4R) in the hypothalamus were also measured by realtime polymerase chain reaction (PCR). In the LC group, food intake reduced while body weight increased significantly compared with the NC and HC groups. Plasma leptin levels increased in the LC (18.5 +/- 8.2 ng/mL) group compared with the NC (8.6 +/- 3.8 ng/mL, P < 0.001) and HC (6.6 +/- 1.9 ng/mL, P < 0.001) groups. Realtime reverse transcription-PCR revealed a decrease in the hypothalamic expression level of only leptin receptor in the LC (0.764, 0.471-4.648 copy/mL) and HC (0.357, 0.129-0.781 copy/mL) groups compared with the NC (1.323, 0.616-2.392 copy/mL; P = 0.01) group, and that there was no significant change in those of insulin receptor, AgRP, Orexin, NPY and MC-4R. Low-carbohydrate, high-fat diet raised body weight, which led to a rising of circulating leptin levels and a reduced expression of leptin receptor in the hypothalamus.

BACKGROUND & AIMS: Hepatic dysfunction is one of the most frequent complications of parenteral nutrition. Very low birth weight (VLBW) infants are more sensitive to liver injury due to physiological immaturity. Our studies in animals showed that glutamine supplementation could attenuate TPN-associated liver injury. The aim of study was to investigate whether parenteral glutamine supplementation can improve hepatic tolerance in VLBW infants. METHODS: We performed a double-blind, randomized, and controlled clinical study to investigate whether parenteral glutamine supplementation can improve hepatic tolerance in VLBW infants. Thirty VLBW infants at two children's centers were randomly assigned to either a control group or a glutamine-supplemented group. The primary endpoints were hepatic function and mortality. The secondary endpoints were the time to achieve full enteral nutrition, episodes of gastric residuals, duration of parenteral nutrition, weight and head circumference gain, length of hospitalization, and days on ventilator. RESULTS: The serum levels of aspartate aminotransferase (AST) and total bilirubin (Tbi) were decreased after PN in the glutamine-supplemented group (P < 0.05). No deaths occurred in this study. Four infants assigned to the control group and two infants in the glutamine-supplemented group were withdrawn from the study, according to intention to treat: relative risk [RR]: 1.182; 95% confidence interval [CI]: 0.937-1.490. CONCLUSIONS: Parenteral glutamine supplementation can improve hepatic tolerance in very low birth weight infant, suggesting a hepato-protective effect.

The aim of this study was to determine the effect of the antioxidant vitamin E (VE) on adiponectin and leptin expression in obese rats. Thirty weaning male Sprague-Dawley rats were divided into three groups as follows: (1) a control group, fed with normal chow; (2) a diet-induced obesity group (DIO), fed with a high-fat diet and (3) an intervention group, fed with a high-fat diet supplemented with VE (350 mg/kg). After 10 weeks of being fed according to these group assignments, rats were weighed and euthanized. Blood and adipose tissues were then immediately collected; mRNA and protein levels of leptin and adiponectin were measured by realtime reverse transcription-polymerase chain reaction and Western blotting. Biomarkers of oxidative stress, including serum levels of 8-epi-prostaglandin-F(2)alpha (8-epi-PGF(2)alpha) and glutathione peroxidase activity, were also examined. Adiponectin and leptin levels were lower in the DIO group than in the control group. VE intervention increased the expression of both leptin and adiponectin (P values < 0.05). Association analysis showed that serum leptin levels correlated positively with body fat mass (r = 0.601, P < 0.05). Both serum leptin and adiponectin levels were associated with the presence of serum 8-epi-PGF2 alpha (leptin, r = 0.513, P < 0.05; adiponectin, r = -0.422, P < 0.05). Administration of VE decreases leptin and adiponectin expression in obese rats. This finding is consistent with the view that antioxidants can play an important role in the treatment of obesity-related diseases.

BACKGROUND: To evaluate the effects of high fat on central appetite regulatory genes in Wistar rats by microarray. METHODS: Sixteen male Wistar rats were randomly assigned to control (15% energy from fat) and high-fat (60% energy from fat) diets for 12 weeks. Body weight and food intake were recorded. Plasma leptin, ghrelin and insulin were measured by radioimmunoassay method. The expression of 111 appetite regulatory genes in the hypothalamus was evaluated by microarray and six genes, including leptin receptor, insulin receptor, orexin, NPY, AgRP, MC-4R, were further evaluated by real-time RT-PCR. RESULTS: Body weight increased significantly in HF group compared with control group, whereas energy intake was similar in the two groups. HF had a time dependent effect on plasma leptin, but insulin and ghrelin level remained stable throughout the study. A positive relation was also found between body weight and plasma leptin (r=0.88, P<0.01). The expression of 27 appetite genes in the hypothalamus was significantly affected by HF diet. However, only the expression of leptin receptor was confirmed lower in HF group than that in control by real-time PCR, which suggested that lower expression of leptin receptor might be another reason for leptin resistance. CONCLUSIONS: HF diet fed rats demonstrated leptin resistance, which could be targeted for obesity treatment.

OBJECTIVE: To assess micronutrients level in children with short bowel syndrome. METHODS: Clinical data of 17 children with short bowel syndrome from April 2004 to July 2006 were collected. They received the measurement of serum vitamin A, E and - carotene by high performance liquid chromatography (HPLC). RESULTS: There were 9 boys and 8 girls with age range of 3 months to 18 years. Eleven children did not need parenteral nutrition (PN), and 6 still depended on PN. Six cases were free of ileocolic valve and 11 cases had ileocolic valve. The length of remaining intestine was more than 75 cm in 5 patients and less than 75 cm in 12 patients. Among 11 cases without PN, 9 were tested for serum iron, zinc and copper levels. Their incidences of below the reference value of vitamin A, E and beta - carotene were 23.5%, 35.3% and 58.8%, respectively. The incidences of below the reference value of vitamin A and beta - carotene were higher in patients with weaned PN, less than 75 cm remaining intestine and without ileocolic valve. The patients with more than 75 cm remaining intestine and still with PN had a higher incidence of below the reference of vitamin E, but the incidence was similar in the patients with or without ileocolic valve. Serum zinc was lower than normal level in 3 cases and serum iron was low in 1 case. CONCLUSION: Supplement of extra micronutrients is essential for short bowl syndrome patient whatever they receive the PN or have normal diets, and follow- up is recommended.

OBJECTIVE: Some neonates especially premature infants, low birth weight infants and extremely low birth weight infants have limited endogenous energy stores. It is necessary to establish continuous administration of postnatal nutrition. The use of parenteral nutrition (PN) in neonates with immaturity of digestive system and intentionally delayed feedings has gained widespread acceptance. PN has been shown to provide sufficient nutrients to maintain growth in newborn infants. The major complication of PN in neonates is PN-associated cholestasis (PNAC). It remains a significant and frequent clinical problem for neonatal practitioners. In some cases, progressive liver damage, liver failure and death may become inevitable. In order to analyze the risk factors of the PNAC in neonates and to provide the evidence of safety and efficiency in clinical nutrition support, the clinical data of 612 neonates who had received PN for more than 5 days during the past 20 years were reviewed. METHODS: Retrospective analysis on data collected from April 1985 to March 2005 was performed. The records of 612 neonates were divided into two groups according to the established Nutrition Support Team (NST) in our hospital. Each group included two sub-groups. Seventy neonates of the first group were divided into PNAC group (n = 6) and non-PNAC group (n = 64); these patients were seen between 1st April 1985 and 31st March 1995. The remaining 542 neonates of the second group who were also divided into 2 groups, i.e. PNAC group (n = 12) and non-PNAC group (n = 530) who were seen from 1st April 1995 through 31st March 2005. The incidence of PNAC between the first group and the second group was compared and the associated factors were analyzed. The PNAC was defined when serum level of direct-bilirubin exceeded 1.5 mg/dl or direct-bilirubin greater than 50% of the bilirubin and excluding cholestasis resulted from other diseases. RESULTS: The total incidence of PNAC in neonates who had received TPN for more than 5 days was 2.94%. The incidence of PNAC of the first and the second decade was 8.57% and 2.21%, respectively (OR = 0.242, 95% CI = 0.088 approximately 0.666). The average gestational age (GA) and birth weight (BW) of PNAC group were less than those of the non-PNAC group (GA: (33 +/- 5) w vs. (36 +/- 4) w, P = 0.009; OR = 0.827, 95% CI = 0.698 approximately 0.980. BW: (2003 +/- 743) g vs. (2393 +/- 764) g, P = 0.045; OR = 1.001, 95% CI = 0.999 approximately 1.002). The PN duration and calorie intake of PNAC group was longer than that of the non-PNAC group (PN duration: 32 +/- 30 d vs. (13 +/- 10) d, P = 0.000; OR = 1.072, 95% CI = 1.032 approximately 1.112. Calorie intake: [(272 +/- 46) kJ/(kg.d)] [(65.0 +/- 10.9) kcal/(kg.d)] (1 kcal = 4.184 kJ) vs. [(232 +/- 55) kJ/(kg.d) (55.5 +/- 13.1) kcal/(kg.d)], (P = 0.002; OR = 1.066, 95% CI = 1.012 approximately 1.122), but the weight gain in the non-PNAC group had a tendency to increase as compared to that of the PNAC group [(20 +/- 27) g/d vs. (9 +/- 19) g/d, P = 0.175]. CONCLUSIONS: The incidence of PNAC was associated with the longer duration of PN, the smaller age at initiation of PN, the higher calorie intake, prematurity and lower birth weight. Establishment of the nutrition support team can normalize the practice of the PN administration and decrease the incidence of the complication with nutrition support. It is a favorable mode and it can provide a safer, more effective and reasonable means in clinical nutrition support. To avoid PNAC, it is suggested that the administration of enteric feeding should start as soon as possible, which may enhance effective contraction of gallbladder and secretion of gastrointestinal hormones, and it is best to avoid high calorie of PN and control the calorie intake under 251.04 approximately 334.72 kJ/(kg.d) [60 approximately 80 kcal/(kg.d)].

The occurrence of eating disorders in Chinese adolescents is increasing. However the cause, diagnosis, treatment and prognosis of this disorder are rarely reported by pediatricians. This paper investigated the cause and treatment of six cases of eating disorders in adolescent patients. The medical data of six cases of eating disorders in the Shanghai Children's Medical Center from January 2003 to September 2005 were retrospectively reviewed. The patients were 5 girls and 1 boy, whose onset ages ranged from 12.4 to 15.8 years. They were initially referred to the clinic between 12.9 to 16.7 years, with a course of disease varying from three to twelve months. The patients' body mass index (BMI) varied from 9.07 to 17.0. Four out of the six patients were hospitalized because of low temperature, low blood pressure, bradycardia, dehydration and multiple systems damages. The other two were treated in the out-patient clinic. Based on the medical history and physical examination as well as laboratory findings, five of them were diagnosed with anorexia nervosa and the other one were bulimia nervosa. All of the patients were under the care of a team consisting of pediatricians, dietitians, psychiatrists and nurses. When the patients whose vital signs were unstable, medical treatment focused on life sustention and they were kept on beds compulsively and given nutrition transfusion. Meanwhile cognition and behavior therapy was administered to help the patients find out the internal and environmental factors related to the development of this disorder, establish a new conception of healthy weight, and correct their abnormal eating behaviors. The patients who had a severe distortion of body image and a big resistance to the treatment were additionally administered with psychiatry drugs. After treatment, three patients set up a healthy eating behavior, their body weights gradually recovered and they had no relapse during a 1-year follow-up. The other three patients retained some abnormal eating behaviors and their body weights were always below normal. It was found that eating disorders in adolescents may be triggered by some environmental factors, such as comments on body shape from their peers, fashion influence, academic pressures, and problems in communication. Since the patients' abnormal eating behaviors were masked or neglected by parents at the early stage of the disease and the clinical presentations were related to multiple systems, it is difficult to make an early diagnosis and treatment. It is important to improve the pediatricians' knowledge of eating disorders of adolescents and perform cooperation between a multidisciplinary team for the early diagnosis and treatment of this disorder.

OBJECTIVE: To establish the value of the resting energy expenditure (REE) in healthy newborns and evaluate relative factors of REE. METHODS: One hundred and fifty-four healthy newborns (75 boys, 79 girls; birth-weight 2,500-3,999 g) were enrolled in this study. The Apgar score at the 5th minute was equal to or more than 8; the postnatal age was equal to or more than 5 days. The newborns had no apparent defect. The mothers had no history of metabolic and endocrine diseases. REE was measured by Deltatrac II in child canopy mode for 30-45 minutes during asleep or quiet awake status. RESULTS: The average REE was (201.8 +/- 25.4) kJ/(kg.d), which was significantly lower than the predicted REE by Schofield formula[(226.1 +/- 4.8) kJ/(kg.d), P = 0.000], the predicted REE was 12.04% higher than the measured REE. There were no differences in sex and ways of delivery. The newborns whose birth-weight was between 2,500-2,999 g were measured in two modes: baby and child mode, and the REE values were significantly higher (122.6 +/- 25.0) kJ/(kg.d) and (208.8 +/- 26.4) kJ/(kg.d), respectively (P = 0.000). CONCLUSIONS: The prediction formula might be improper for calculating the REE in newborn infants. The indirect calorimetry was the better way to know the actual REE of newborns. The authors recommended that in child mode the measurement of REE in newborns would be the indirect calorimetry, and the REE in healthy newborns was (201.8 +/- 25.4) kJ/(kg.d).
