Abstract
Currently, most predictions of metabolic-associated fatty liver disease (MAFLD) in school-aged children utilize indicators that usually predict nonalcoholic fatty liver disease (NAFLD). The present study aimed to develop new predictive models and predictors for children with MAFLD, which could enhance the feasibility of MAFLD screening programs in the future. A total of 331 school-aged overweight/obese children were recruited from six primary schools in Ningbo city, China. Hepatic steatosis and fibrosis were detected with controlled attenuation parameter (CAP) and liver stiffness measurement (LSM), respectively. Machine learning methods were adapted to build a set of variables to predict MAFLD in children. Then, the area under the curve (AUC) of multiple models and indices was compared to predict pediatric MAFLD. Compared with non-MAFLD children, children with MAFLD had more obvious metabolic disturbances, as they had higher anthropometric indicators, alanine aminotransferase, fasting plasma glucose, and inflammation indicators (white blood cell count, hemoglobin, neutrophil count) (all P < 0.05). The optimal variables for all subjects selected by random forest (RF) were alanine aminotransferase, uric acid, insulin, and BMI. The logistic regression (LR) model performed best, with AUC values of 0.758 for males and 0.642 for females in predicting MAFLD. LnAI-BMI, LnAI, and LnAL-WHtR were approving indices for predicting pediatric MAFLD in all participants, boys and girls individually. CONCLUSIONS This study developed LR models and sex-specific indices for predicting MAFLD in overweight/obese children that may be useful for widespread screening and identification of children at high risk of MAFLD for early treatment. WHAT IS KNOWN • Most of the indicators predicting pediatric MAFLD are derived from the predictive indicators for NAFLD, but the diagnostic criteria for MAFLD and NAFLD are not exactly the same. • The accuracy of predictors based on routine physical examination and blood biochemical indicators to diagnose MAFLD is limited. WHAT IS NEW • This study developed indicators based on routine examination parameters that have approving performance for MAFLD, with AUC values exceeding 0.70.

Abstract
BACKGROUND Malnutrition including undernutrition, overnutrition, and micronutrient deficiencies are considerable problems worldwide, with variable burdens among different communities. Its complications include physical and cognitive impairment, with the probability of irreversible lifelong consequences. We aimed to assess the prevalence of undernutrition, overweight, obesity, and anemia in preschoolers, being a risk group for developmental adverse events. METHODS We recruited 505 healthy preschool children, with a male: female ratio of 1.05:1. Children with chronic diseases were excluded. We used anthropometry and complete blood count to screen for malnutrition and anemia. RESULTS The mean age of the study group was 3.8 ± 1.4 years (1.02-7). The screening results were average in 228 (45.1%) children, while 277 (54.9%) children had either abnormal anthropometry, anemia, or both. We observed undernutrition in 48 (9.5%) children; among them, 33 (6.6%) were underweight, 33 (6.6%) wasted, and 15 (3%) were stunted, with no significant difference between children aged below or above five. We identified overnutrition in 125 (24.8%); 43 (8.5%) were overweight, 12 (2.4%) were obese, and 70 (13.9%) had a high body mass index Z score, not qualifying the definition of overweight. Anemia was diagnosed in 141 (27.9%) children and was significantly more frequent among older children without gender discrimination. About 10% (50 children) had both anemia and abnormal anthropometry. The frequency of abnormal anthropometry was comparable between children with anemia and those with normal hemoglobin. CONCLUSION Malnutrition and anemia in preschoolers are still a heavy burden affecting about half of our study group, with an upward trend towards the overnutrition side. Anemia is still a moderate public health problem in preschoolers.

Abstract
BACKGROUND Both low-carbohydrate (LC) and calorie-restricted (CR) diets have been shown to have metabolic benefits. However, the two regimens have yet to be thoroughly compared. We conducted a 12-week randomized trial to compare the effects of these diets separately and in combination on both weight loss and metabolic risk factors in overweight/obese individuals. METHODS A total of 302 participants were randomized to LC diet (n = 76), CR diet (n = 75), LC + CR diet (n = 76), or normal control (NC) diet (n = 75) using a computer-based random number generator. The primary outcome was the change in body mass index (BMI). The secondary outcomes included body weight, waist circumference, waist-to-hip ratio, body fat, and metabolic risk factors. All participants attended health education sessions during the trial. RESULTS A total of 298 participants were analyzed. BMI change over 12 weeks was - 0.6 (95% CI, - 0.8 to - 0.3) kg/m2 in NC, - 1.3 (95% CI, - 1.5 to - 1.1) kg/m2 in CR, - 2.3 (95% CI, - 2.6 to - 2.1) kg/m2 in LC, and - 2.9 (95% CI, - 3.2 to - 2.6) kg/m2 in LC + CR. LC + CR diet was more effective than LC or CR diet alone at reducing BMI (P = 0.001 and P < 0.001, respectively). Furthermore, compared with the CR diet, the LC + CR diet and LC diet further reduced body weight, waist circumference, and body fat. Serum triglycerides were significantly reduced in the LC + CR diet group compared with the LC or CR diet alone. Plasma glucose, homeostasis model assessment of insulin resistance, and cholesterol concentrations (total, LDL, and HDL) did not change significantly between the groups during the 12-week intervention. CONCLUSIONS The reduction of carbohydrate intake without restricting caloric intake is more potent to achieve weight loss over 12 weeks when compared to a calorie-restricted diet in overweight/obese adults. The combination of restricting carbohydrate and total calorie intake may augment the beneficial effects of reducing BMI, body weight, and metabolic risk factors among overweight/obese individuals. TRIAL REGISTRATION The study was approved by the institutional review board of Zhujiang Hospital of Southern Medical University and registered at the China Clinical Trial Registration Center (registration number: ChiCTR1800015156).

Abstract
The present study examined associations between sleep and physical activity among a diverse sample of 97 urban children (ages 7-9) with persistent asthma. Differences in associations were evaluated by race/ethnicity and weight status. The extent to which sleep moderated the association between lung function and physical activity was also evaluated. Generalized linear models were utilized to examine associations. Findings indicated that, among the aggregate sample, more frequent nighttime awakenings were associated with less time spent engaging in moderate-to-vigorous physical activity (MVPA). Important differences in these associations were identified by both race/ethnicity and weight status. Better lung function was associated with, (a) higher levels of MVPA for children with better sleep efficiency and fewer nighttime awakenings, and (b) lower levels of MVPA for children with poorer sleep efficiency and more frequent nighttime awakenings. In short, sleep mattered with respect to children's physical activity levels in this sample.

Abstract
PURPOSE Vitamin D has been identified to have a relation to the development of insulin resistance-related diseases, such as type 2 diabetes (T2D). T2D is often associated with obesity and dyslipidemia. Our study aimed to analyze the relationship between vitamin D and lipid profile in patients with T2D. METHODS A total of 446 T2D patients who were hospitalized from January 2015 to December 2016 were recruited. Baseline characteristics were recorded, including body mass index (BMI), serum level of 25 hydroxy vitamin D (25(OH)D), and other biochemical indicators. T2D patients were divided into normal-weight group and overweight/obese group according to their BMI. Subgroup analysis was conducted after patients were subdivided using the quartet-method according to serum level of 25(OH)D. Differences in glucose and lipid metabolism indicators were analyzed. The correlation between serum 25(OH)D and lipid profiles was assessed by the multiple linear regression. RESULTS The levels of serum 25(OH)D and high-density lipoprotein cholesterol in T2D patients of overweight/obesity group were significantly lower than those in normal-weight group, while the levels of triglyceride (TG) and HOMA-IR were significantly higher (P < 0.05). Subgroup analysis uncovered that total cholesterol (TC) and TG levels were lower with higher 25(OH)D in normal weight T2D patients. In overweight/obese T2D patients, TG level was lower in patients with higher 25(OH)D (P < 0.05). There were no significant differences in low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBG), fasting insulin (FINS), and hemoglobin Alc (HbAlc) among Q1-Q4 in both normal weight and overweight/obese groups. Pearson test showed that serum 25(OH)D was positively correlated with high density lipoprotein cholesterol (HDL-C), and negatively correlated with TC and TG. Serum 25(OH)D was unrelated to low density lipoprotein cholesterol (LDL-C) in both groups. Multiple linear regression analysis only demonstrated an independent negative correlation between 25(OH)D and TG levels in the overweight/obese group (P < 0.01). CONCLUSIONS In overweight/obese patients with T2D, serum 25(OH)D was independently, negatively correlated with TG. Vitamin D supplementation should be guaranteed in patients with diabetes, especially with obese T2D.

Abstract
Purpose To examine changes in physical activity (PA) during a behavioral weight-loss intervention and determine baseline factors associated with PA goal achievement. Methods Overweight/obese community-dwelling adults with valid PA accelerometer data (N=116; mean age 51.7 years; 89% female; 83% non-Hispanic White) were recruited into a single-arm prospective cohort study examining the effects of a 12-month intervention that included 24 in-person group sessions, weight-loss, calorie, fat gram, and PA goals, self-monitoring, and feedback. Minutes of moderate-to-vigorous (MV) PA and steps were measured using a waist-worn accelerometer (ActiGraph GT3x) at baseline, 6 months, and 12 months. Achievement of the 150 minute/week MVPA goal was examined using total minutes and bout minutes (i.e., counting only PA occurring in bouts ≥10 minutes in length). Change in PA was analyzed using non-parametric tests for multiple comparisons. Associations of factors with meeting the PA goal were modeled using binary logistic regression. Results At 6 months, there were increases from baseline in MVPA (median [p25, p75]: 5.3 [-0.9, 17.6] minutes/day) and steps (863 [-145, 2790] steps/day), both p<0.001. At 12 months, improvements were attenuated (MVPA: 2.4 [-2.0, 11.4] minutes/day, p=0.047; steps: 374[-570, 1804] p=0.14). At 6 months, 33.6% of individuals met the PA goal (using total or bout minutes). At 12 months, the percent meeting the goal using total MVPA [31%] differed from bout MVPA [22.4%]. Male gender (OR=4.14, p=0.027) and an autumn program start (versus winter; OR=3.39, p=0.011) were associated with greater odds of goal achievement at 6 months. Conclusions The intervention increased PA goal achievement at 6 and 12 months with many making clinically meaningful improvements. Our results suggest female participants may require extra support toward improving PA levels.

Abstract
PURPOSE The hormone ghrelin has an important role in a wide range of metabolic and nonmetabolic processes. Ghrelin gene polymorphisms have been reported to influence obesity or lipid abnormalities in some ethnic groups. This study was conducted mainly to examine the possible association of ghrelin - 604 G > A and Leu72Met polymorphisms with obesity and related traits in a Southwest Chinese population. METHODS Three hundred and eighty-six Han Chinese individuals (118 obese and 268 normal weight control subjects) in the Chengdu area were studied using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Clinical and biochemical parameters were also analyzed. RESULTS The genotype and allele frequencies of ghrelin gene polymorphisms in participants with obesity showed no significant difference compared to those in nonobese controls. However, in the nonobese control group, carriers of genotype Met/Met at the Leu72Met site had higher serum TC and LDL-C concentrations than those of the Leu/Leu genotype (P < 0.05). When nonobese subjects were stratified by sex, the genotype-dependent effects on TC and LDL-C were more evident, although this was observed only in females. In addition, genotype-related effects on these lipid parameters at this site were observed in male obese subjects only. CONCLUSIONS The Leu72Met polymorphism of the ghrelin gene is associated with altered plasma TC and LDL-C concentrations, and the effects on TC and LDL-C levels are sex-dependent in both nonobese and obese subjects in the Chinese population of the Chengdu area.

Abstract
Background In recent years, the exciting emergence of circulating miRNAs as stable, reproducible, and consistent among individuals has opened a promising research opportunity for the detection of non-invasive biomarkers. A firm connection has been established between circulating miRNAs and glycaemic as well as metabolic homeostasis, showing that levels of specific miRNAs vary under different physio-pathological conditions. Objective In this pilot study, we investigated the expression of candidate miRNAs, hsa-miR-191-3p and hsa-miR-375, in relation to biomarkers associated with insulin sensitivity in a subgroup (n=58) of subjects participating to the European I.Family Study, a project aimed to assess the determinants of eating behaviour in children and adolescents and related health outcomes. The sample included overweight/obese children/adolescents since overweight/obesity is a known risk factor for impaired glucose homeostasis and metabolic disorders. Biological targets of candidate miRNAs were also explored in silico. Results We observed a significant association of the two miRNAs and early changes in glycaemic homeostasis, independent of covariates including country of origin, age, BMI z-score, puberty status, highest educational level of parents, total energy intake, energy from fats, energy from carbohydrates, and energy from proteins. Conclusion Identification of circulating miRNAs associated with insulin impairment may offer novel approaches of assessing early variations in insulin sensitivity and provide evidence about the molecular mechanisms connected to early changes in glycaemic homeostasis.

Abstract
BACKGROUND Several biologic mechanisms, including inflammation and immune changes, have been proposed to explain the role of obesity in prostate cancer (CaP) progression. Compared to men of a healthy weight, overweight and obese men are more likely to have CaP recurrence post-prostatectomy. Obesity is related to inflammation and immune dysregulation; thus, weight loss may be an avenue to reduce inflammation and reverse these immune processes. OBJECTIVES This study explores the reversibility of the biological mechanisms through intentional weight loss using a comprehensive weight management program in men undergoing prostatectomy. Outcomes include blood and tissue biomarkers, microtumor environment gene expression, inflammation markers and Dietary Inflammatory Index (DII) scores. METHODS Twenty overweight men undergoing prostatectomy participated in this study. Fifteen men chose the intervention and 5 men chose the nonintervention group. The intervention consisted of a comprehensive weight loss program prior to prostatectomy and a weight maintenance program following surgery. Prostate tissue samples were obtained from diagnostic biopsies before the intervention and prostatectomy samples after weight loss. Blood samples and diet records were collected at baseline, pre-surgery after weight loss and at study end after weight maintenance. Immunohistochemistry and NanoString analysis were used to analyze the tissue samples. Flow cytometry was used to assess circulating immune markers. Inflammation markers were measured using Luminex panels. RESULTS The intervention group lost >5% body weight prior to surgery. DII scores improved during the weight loss intervention from baseline to pre-surgery (P = 0.002); and between group differences were significant (P = 0.02). DII scores were not associated with IL-6 nor hsCRP. In the intervention, CXCL12, CXCR7, and CXCR4 (C-X-C motif chemokine ligand/receptor) and Ki67 expression decreased in the prostate tissue from biopsy to surgery (P = 0.06), yet plasma CXCL12 increased during the same timeframe (P = 0.009). The downregulation of several genes (FDR<0.001) was observed in the intervention compared to the non-intervention. Changes in immune cells were not significant in either group. CONCLUSION This feasibility study demonstrates that in overweight men with localized CaP, weight loss alters blood, and tissue biomarkers, as well as tumor gene expression. More research is needed to determine the biological and clinical significance of these findings.

Abstract
PURPOSE The study aimed to investigate the relationship between elevated maternal body mass index (BMI) and foetal chromosomal aberrations by performing single-nucleotide polymorphism (SNP) array-based genetic testing on products of conception (POC). METHODS We retrospectively reviewed the data for 1068 assisted reproductive technology (ART)-conceived POC originated from 1068 patients with early spontaneous miscarriage. First, all types of chromosomal abnormalities were defined. Then, the baseline characteristics, including maternal age, BMI, thyroid-stimulating hormone (TSH), gestational age, fertilization method, reasons for fertility treatment, embryo transfer (ET) cycle, stage of embryo development and the embryo morphology grade, were compared between chromosomally normal and abnormal POC groups. Finally, a multivariate logistic regression model was used to analyse various factors affecting the foetal chromosomal abnormality rate. RESULTS The SNP array results showed that 45.3% (484/1068) of POC were chromosomally normal and that 54.7% (584/1068) of POC presented chromosomal abnormalities. Of these 584 chromosomally abnormal POC, 388 (66.4%) were trisomy, 42 (7.2%) had a monosomy, 68 (11.6%) were found with segmental aneuploidy, 46 (7.9%) were mosaic, 28 (4.8%) were identified as polyploidy and 12 (2.1%) were euploid samples with uniparental disomy (UPD). Multivariate logistic regression results showed that the risk of miscarrying chromosomally abnormal POC increased 1.424-fold in women with normal BMI compared to women with an elevated BMI (≥ 25 kg/m2) (OR = 1.424, 95% CI = 1.074-1.888, p = 0.014). CONCLUSION Women with an elevated BMI (≥ 25 kg/m2) are more likely to miscarry chromosomally normal POC.

Abstract
BACKGROUND AND AIMS While excess energy intake and physical inactivity constitute the obvious causes of body fat accumulation, persistent organic pollutants (POPs) are novel factors that have been linked to cardiometabolic disorders. Major sources of POPs are animal fats including fatty fish. Given the putative protective effects of fish on cardiovascular disease, we explored whether high consumption of fatty fish increased serum concentrations of POPs. METHODS AND RESULTS Men and women aged 35-70 years with body mass index between 25 and 38 kg/m2 and at least 1 cardiometabolic component were randomized to high intakes of fatty fish (mostly farmed salmon, ∼630 g/week; n = 45), high intakes of nuts (∼200 g/week; n = 42) or a control group following their usual diet but restricting fatty fish and nuts for 6 months (n = 44). Concentrations of 15 POPs (5 organochlorinated compounds, 2 dioxin-like polychlorinated biphenyls and 8 non-dioxin-like polychlorinated biphenyls) and cardiometabolic risk factors were measured at baseline and end of the study. Results showed that changes in concentrations of individual and classes of POPs did not differ between the dietary groups and controls (p > 0.05). Among cardiometabolic risk factors HDL-cholesterol increased in the fatty fish group compared to controls (+0.10 mmol/L, CI (0.05-0.20); p = 0.005) while no changes were observed in the group consuming nuts. CONCLUSION Fatty fish consumption for 6 months did not increase the serum concentrations of POPs in individuals with overweight or obesity and metabolic risk. While this finding appears reassuring regarding short-term intakes of farmed salmon, long term variations in POPs in adipose stores require further study.

Abstract
AIMS To investigate the association of obesity phenotypes with non-obese components of metabolic syndrome (MetS) by considering the presence of general adiposity and central obesity. METHODS We analyzed the data of population-based cross-sectional study of 981 adults' individuals who were community dwelling in urban population of Babol, the north of Iran. The demographic characteristics and anthropometric measures and hypertension were collected with standard method by trained nurses. The fasting blood sugar, CHL, TG, HDL-C and LDL-C were measured by enzymatic method. The presence of cardiometabolic risk factors were analyzed according to the combination of obesity phenotypes either overweight/obese or central obese. The logistic regression model was used to calculate the adjusted odds ratio (OR) of obesity phenotypes in compared with normal weight not central obese in association of presence of metabolic abnormality. RESULTS The 394 (40.6%) individuals were both overweight/obese and central obese and 295 (30.1%) persons were "normal weight not central obese" and the minority 28(2.9%) were normal weight but central obese and the remainder 260 (26.5%) were "overweight/obese not central obese". Overweight/obese not central obese increased significantly the odds of presence of ≥2 non-obese components of metabolic abnormality by 2.17 times (95%CI OR: 1.51, 3.13) but the OR was elevated for the joint phenotypes of overweight/obese and central obese (OR = 4.16 (95%CI: 2.85, 6.06) as compare with normal weight not central obese. CONCLUSIONS Overweight/obese alone increased the risk of cardiometabolic abnormality but being overweight/obese and central obese a further elevated the risk compared with "normal weight not central obese".

Abstract
Food cue-reactivity tasks are used to induce and evaluate food cravings. Extant research has implicated the role of tasting foods in heightening cue-elicited food craving. The present study was the first to evaluate a taste manipulation during a food cue-reactivity task to optimize cue-elicited craving and predict food intake. Participants with overweight/obesity (N = 35; M age = 33.46 years [SD = 13.27]; M BMI = 32.91 kg/m2 [SD = 5.34]) engaged in one laboratory session and were randomized to a 'No Taste' or 'Taste' condition. All participants reported baseline food craving and observed two types of high-calorie food cues during a cue-reactivity task: photographic and real foods. The Taste group tasted real food cues and the No Taste group did not. Cue-elicited craving was assessed after the presentation of each food cue. Calorie intake of palatable foods was subsequently measured during a bogus taste test. Results indicated that cue-elicited craving to high-calorie foods was greater for the No Taste relative to the Taste group and that calorie intake was greater for the Taste relative to the No Taste group; both effects were nonsignificant, but of medium-size. Cue-elicited craving was significantly greater following exposure to high-calorie real food cues compared to photographic food cues. Results provide initial evidence that presenting high-calorie real (vs. photographic) food cues and forgoing taste manipulation during a food cue-reactivity task may optimize cue-elicited craving, and that taste manipulation could increase subsequent food intake. Future research should be conducted to replicate findings in larger samples with greater power to detect significant effects.

Abstract
OBJECTIVE The present study examined the prevalence of and risk factors for malnutrition in a population-based cohort of women of childbearing age in rural Bangladesh. DESIGN A cross-sectional study that collected pre-pregnancy weight, height, and data on selected risk factors for nutritional status of women. SETTING The study was conducted in Sylhet District of Bangladesh. SUBJECTS Study subjects included 13 230 non-pregnant women of childbearing age. Women were classified into underweight (<18·5 kg/m2), normal (18·5-24·9 kg/m2) and overweight/obese (≥25·0 kg/m2) using BMI; and into moderate to severe stunting (<150 cm), mild stunting (150-<155 cm) and normal (≥155 cm) using height. Two multinomial logistic regression models were fitted for BMI: model 1 examined individual and household factors associated with BMI, and model 2 additionally examined the association of community variables. The same analysis was conducted for height. RESULTS Prevalence of underweight, overweight/obesity and moderate to severe stunting was 37·0, 7·2 and 48·6 %, respectively. Women's education and household wealth were inversely related to both underweight status and stunting. Underweight rate was significantly lower in the post-harvest season. Women with any education and who belonged to households with higher wealth were more likely to be overweight/obese. CONCLUSIONS The study documented high underweight and stunting, and moderate overweight/obesity rates among rural Bangladeshi women; and recommends design and implementation of a multidimensional intervention programme based on individual-, household- and community-level risk factors that can address underweight, stunting and overweight/obesity to improve the nutritional status of women of childbearing age in Bangladesh.

Abstract
PURPOSE To compare intakes of dietary iron and enhancers and inhibitors of iron absorption between overweight/obese (OW/OB) adolescents and their normal weight (NW) peers, and between parental education levels stratified by weight status. METHODS This was a comparative cross-sectional study of adolescents (n 121 OW/OB and n 102 NW) aged 12-14 years, attending a secondary school in Nonthaburi province, Thailand. Socio-demographic data were obtained from participants' parents using a questionnaire. Participants recorded their intakes for 3 non-consecutive days, using a prospective food record. RESULTS Compared with NW adolescents, OW/OB adolescents consumed more total protein and animal protein after adjustment for energy intake (both p = 0.047). OW/OB adolescents whose mothers were less educated consumed more total iron and available iron after adjustment for energy intake, compared with their OW/OB peers whose mothers were more educated (p = 0.045 and p = 0.040). NW adolescents with more highly educated mothers had higher absolute and energy-adjusted fibre intakes (both p = 0.047). However, NW adolescents of mothers with a high-intermediate level of education consumed less calcium, after adjustment for energy intake (p = 0.028). CONCLUSIONS OW/OB adolescents with less educated mothers had higher energy-adjusted intakes of iron and available iron. Dietary differences in OW/OB adolescents relative to maternal education, and other socioeconomic indicators, should be explored in a nationally representative data set.

Abstract
A main target of growth hormone (GH) is adipose tissue in human body. The GH secretion in obesity patients is impaired. It is needless to say that growth hormone receptor (GHR) is necessary in GH hormone signaling. The purpose of the present study is to examine the association between single nucleotide polymorphisms (SNPs) and the development of obesity. A total of 211 overweight/obese subjects with a body mass index (BMI) ≥23 kg/m2 and 157 nonoverweight/obese controls with a BMI of 18.5-23.0 kg/m2 were involved in this study. Seven SNPs including the rs6451620 (intron), rs4130114 (intron), rs4410646 (intron), rs6898743 (intron), rs4394131 (intron), rs6182 (Cys440Phe), and rs6184 (Pro579Thr) and rs2229765 SNPs of GHR gene were genotyped. Genotyping was performed using custom DNA chip. SNPStats was used to calculate the odds ratio, 95% confidence interval, and P-value. The link-age disequilibrium block and haplotypes among seven SNPs were determined using Haploview version 4.2. Dominant, recessive, and log-additive genetic models were conducted for genetic analyzing. Among tested SNPs in GHR gene, rs4410646 and rs6898743 showed significant association with obesity (rs4410646, P=0.02 in dominant model and P=0.036 in log-additive model; rs6898743, P=0.039 in dominant model and P=0.044 in log-additive model).

Abstract
A main target of growth hormone (GH) is adipose tissue in human body. The GH secretion in obesity patients is impaired. It is needless to say that growth hormone receptor (GHR) is necessary in GH hormone signaling. The purpose of the present study is to examine the association between single nucleotide polymorphisms (SNPs) and the development of obesity. A total of 211 overweight/obese subjects with a body mass index (BMI) ≥23 kg/m2 and 157 nonoverweight/obese controls with a BMI of 18.5–23.0 kg/m2 were involved in this study. Seven SNPs including the rs6451620 (intron), rs4130114 (intron), rs4410646 (intron), rs6898743 (intron), rs4394131 (intron), rs6182 (Cys440Phe), and rs6184 (Pro579Thr) and rs2229765 SNPs of GHR gene were genotyped. Genotyping was performed using custom DNA chip. SNPStats was used to calculate the odds ratio, 95% confidence interval, and P-value. The link-age disequilibrium block and haplotypes among seven SNPs were determined using Haploview version 4.2. Dominant, recessive, and log-additive genetic models were conducted for genetic analyzing. Among tested SNPs in GHR gene, rs4410646 and rs6898743 showed significant association with obesity (rs4410646, P=0.02 in dominant model and P=0.036 in log-additive model; rs6898743, P=0.039 in dominant model and P=0.044 in log-additive model). In summary, these results suggest that GHR gene polymorphisms might play a role in the development of obesity in the Korean population.

Abstract
BACKGROUND Dietary patterns that are considered healthy (eg, the Dietary Approaches to Stop Hypertension diet and Mediterranean diet) may be more successful in reducing typical cardiovascular disease risks compared to dietary patterns considered unhealthy (eg, energy-dense diets such as the typical American diet). OBJECTIVE This study assessed the effects of a Korean diet, the 2010 Dietary Guidelines for Americans (DGA), and a typical American diet on cardiometabolic risk factors, including lipid levels and blood pressure, in overweight, non-Asian individuals in the United States with elevated low-density lipoprotein cholesterol. DESIGN/INTERVENTION The study was a three-period crossover, controlled-feeding study from January 2012 to May 2012. Thirty-one subjects were randomly allocated to one of six possible sequential orders for consuming the three diets for 4 weeks, each separated by a 10-day break. Data analysis included 27 subjects on the Korean diet periods and 29 in the DGA and typical American diet periods. Subjects remained weight stable. MAIN OUTCOME MEASURES Lipid profile, blood pressure, insulin, glucose, and 24-hour urinary sodium were determined at baseline and at the end of each diet period. STATISTICAL ANALYSES PERFORMED The additive main effects multiplicative interactions model was used to test for a subject by diet interaction. Differences among diets were determined using a mixed-models procedure (PROC MIXED) with random intercept for each subject. RESULTS Total cholesterol and low-density lipoprotein cholesterol significantly decreased on Korean (P<0.0001 and P<0.01, respectively) and DGA (P<0.01 and P<0.05, respectively) diets, but not on the typical American diet. Although an unfavorable outcome, high-density lipoprotein cholesterol significantly decreased on all three diets (Korean: P<0.0001; DGA: P<0.0001; typical American: P<0.05). No diet had a significant effect on serum triglycerides, but a slight increase in triglycerides in the Korean and decrease in the DGA resulted in a significant difference between these two diets (P<0.01). All three diets caused modest decreases in systolic and diastolic blood pressure, which reached statistical significance for DGA only (P<0.05 and P<0.01, respectively). No diet had significant effect on fasting insulin, whereas fasting glucose decreased significantly on the Korean (P<0.01) and typical American (P<0.05) diets only. Urinary sodium output decreased significantly on DGA (P<0.0001). CONCLUSIONS After a 4-week feeding period, Korean and DGA diet patterns resulted in positive changes in cardiovascular disease risk factors.

Abstract
Background A critical need exists to better understand the physiological sequel of vitamin D supplementation in obese individuals and African Americans. The aim was to comprehensively evaluate dose- and time-responses of a panel of vitamin D biomarkers to vitamin D supplements in this population. Methods We conducted a 16-week randomized, double-blinded, and placebo-controlled clinical trial. Seventy overweight/obese African Americans (age 13–45 years, 84 % females) with 25-hydroxyvitamin D [25(OH)D] concentrations ≤20 ng/mL were randomly assigned to receive a supervised monthly oral vitamin D3 of 18,000 IU (~600 IU/day, n = 17), 60,000 IU (~2000 IU/day, n = 18), 120,000 IU (~4000 IU/day, n = 18), or placebo (n = 17). Results There were significant dose- and time-responses of circulating 25(OH)D, 1,25-dihydroxyvitamin D [1,25(OH)2D], and intact parathyroid hormone (iPTH), but not fibroblast growth factor-23 (FGF-23), phosphorus and urine calcium to the vitamin D supplements. The mean 25(OH)D concentrations in the 2000 IU and 4000 IU groups reached ≥30 ng/mL as early as 8-weeks and remained at similar level at 16-weeks. The increase of 25(OH)D was significantly higher in the 4000 IU group than all the other groups at 8-weeks. The increase of 1,25(OH)2D was significantly higher in the 2000 IU and 4000 IU groups than the placebo at 8-weeks. Only the 4000 IU compared to the placebo significantly reduced iPTH at 8- and 16-weeks. Conclusions Our RCT, for the first time, comprehensively evaluated time- and dose- responses of vitamin D supplementation in overweight/obese African Americans with suboptimal vitamin D status. Circulating 25(OH)D, 1,25(OH)2D, and iPTH, but not FGF-23, phosphorus and urine calcium, respond to vitamin D supplementation in a time- and dose–response manner. By monthly dosing, 2000 IU appears to be sufficient in achieving a 25(OH)D level of 30 ng/mL in this population. However, importantly, 4000 IU, rather than 2000 IU, seems to suppress iPTH. If replicated, these data might be informative in optimizing vitamin D status and providing individualized dosing recommendation in overweight/obese African Americans. Trial registration ClinicalTrials.gov number: NCT01583621, Registered on April 3, 2012.

Abstract
The majority of people with type 2 diabetes are overweight or obese, and weight loss is a recommended treatment strategy. A systematic review and meta-analysis was undertaken to answer the following primary question: In overweight or obese adults with type 2 diabetes, what are the outcomes on hemoglobin A1c (HbA1c) from lifestyle weight-loss interventions resulting in weight losses greater than or less than 5% at 12 months? Secondary questions are: What are the lipid (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides) and blood pressure (systolic and diastolic) outcomes from lifestyle weight-loss interventions resulting in weight losses greater than or less than 5% at 12 months? And, what are the weight and metabolic outcomes from differing amounts of macronutrients in weight-loss interventions? Inclusion criteria included randomized clinical trial implementing weight-loss interventions in overweight or obese adults with type 2 diabetes, minimum 12-month study duration, a 70% completion rate, and an HbA1c value reported at 12 months. Eleven trials (eight compared two weight-loss interventions and three compared a weight-loss intervention group with a usual care/control group) with 6,754 participants met study criteria. At 12 months, 17 study groups (8 categories of weight-loss intervention) reported weight loss <5% of initial weight (-3.2 kg [95% CI: -5.9, -0.6]). A meta-analysis of the weight-loss interventions reported nonsignificant beneficial effects on HbA1c, lipids, or blood pressure. Two study groups reported a weight loss of ≥5%: a Mediterranean-style diet implemented in newly diagnosed adults with type 2 diabetes and an intensive lifestyle intervention implemented in the Look AHEAD (Action for Health in Diabetes) trial. Both included regular physical activity and frequent contact with health professionals and reported significant beneficial effects on HbA1c, lipids, and blood pressure. Five trials (10 study groups) compared weight-loss interventions of differing amounts of macronutrients and reported nonsignificant differences in weight loss, HbA1c, lipids, and blood pressure. The majority of lifestyle weight-loss interventions in overweight or obese adults with type 2 diabetes resulted in weight loss <5% and did not result in beneficial metabolic outcomes. A weight loss of >5% appears necessary for beneficial effects on HbA1c, lipids, and blood pressure. Achieving this level of weight loss requires intense interventions, including energy restriction, regular physical activity, and frequent contact with health professionals. Weight loss for many overweight or obese individuals with type 2 diabetes might not be a realistic primary treatment strategy for improved glycemic control. Nutrition therapy for individuals with type 2 diabetes should encourage a healthful eating pattern, a reduced energy intake, regular physical activity, education, and support as primary treatment strategies.

Abstract
This study investigated the differences in eating disorder psychopathology, appearance satisfaction, and self-esteem between 194 overweight/obese college women with and without binge eating. Participants were categorized as binge eating (BE; n=56) or non-binge eating (NBE; n=138) based on reports of binge eating at least once per week on average for the past 28days and no episodes of vomiting or laxative use in the past 28days. The BE group had significantly greater levels of eating, weight, and shape concerns and lower levels of appearance satisfaction and self-esteem than the NBE group. For the BE group, binge eating frequency was negatively correlated with dietary restraint. Results are generally consistent with studies utilizing clinical and community samples. The findings extend such research by examining binge eating in a sample of overweight and obese college women and indicating that overall appearance satisfaction is lower among women with binge eating. Study findings also highlight potential issues to address in obesity and binge eating intervention efforts for college populations. Future research is needed to replicate these findings in additional samples of college women and men.
