    Full Text Available Aim: Nowadays increasing blood pressure is the most important risk factor of coronary, cerebral and renal vessel diseases. Epidemiological studies indicate that Physical inactivity adversely affects the blood pressure in postmenopausal women. The purpose of this study was to determine the impact of aerobic on body composition and blood pressure in postmenopausal women. Methods: 20 healthy postmenopausal women with similar age and weight were randomly devided in intervention and control groups. Subjects completed an informed consent form and health history questionnaire. The intervention group was trained in an aerobic exercise program for 8 weeks (3 sessions weekly. Weight, body fat percentage (BF%, body mass index (BMI, waist to hip ratio (WHR, Lean body mass and blood pressure (BP were measured in the beginning and the end of the study for all of the subjects. Data were analyzed by the Paired t-test and independent t- test. Results: The results showed that BF% , WHR, BMI decreased and Lean body mass increased significantly in training group after 8 weeks training (P0.05. Conclusions: It seems that a period of aerobic training for 8 weeks can be effective as a non-pharmacological treatment strategy for improvement some physical fitness and body composition indexes, blood pressure in postmenopausal women.

    The purpose of this study was to determine the effect of a combined weights and plyometrics program on golf drive performance. Eleven male golfers' full golf swing was analyzed for club head speed (CS) and driving distance (DD) before and after an 8-week training program. The control group (n = 5) continued their normal training, while the experimental group (n = 6) performed 2 sessions per week of weight training and plyometrics. Controls showed no significant (p > or = 0.05) changes, while experimental subjects showed a significant increase (p golf drive performance were attributed to an increase in muscular force and an improvement in the sequential acceleration of body parts contributing to a greater final velocity being applied to the ball. It was concluded that specific combined weights and plyometrics training can help increase CS and DD in club golfers. PMID:14971982

  6. Dynamics of Delayed p53 Mutations in Mice Given Whole-Body Irradiation at 8 Weeks

    Purpose: Ionizing irradiation might induce delayed genotoxic effects in a p53-dependent manner. However, a few reports have shown a p53 mutation as a delayed effect of radiation. In this study, we investigated the p53 gene mutation by the translocation frequency in chromosome 11, loss of p53 alleles, p53 gene methylation, p53 nucleotide sequence, and p53 protein expression/phosphorylation in p53+/+ and p53+/- mice after irradiation at a young age. Methods and Materials: p53+/+ and p53+/- mice were exposed to 3 Gy of whole-body irradiation at 8 weeks of age. Chromosome instability was evaluated by fluorescence in situ hybridization analysis. p53 allele loss was evaluated by polymerase chain reaction, and p53 methylation was evaluated by methylation-specific polymerase chain reaction. p53 sequence analysis was performed. p53 protein expression was evaluated by Western blotting. Results: The translocation frequency in chromosome 11 showed a delayed increase after irradiation. In old irradiated mice, the number of mice that showed p53 allele loss and p53 methylation increased compared to these numbers in old non-irradiated mice. In two old irradiated p53+/- mice, the p53 sequence showed heteromutation. In old irradiated mice, the p53 and phospho-p53 protein expressions decreased compared to old non-irradiated mice. Conclusion: We concluded that irradiation at a young age induced delayed p53 mutations and p53 protein suppression.

    2007-11-01

    Full Text Available Abstract Background Household food availability is consistently linked to dietary intake; yet behavioral weight control treatment includes only minimal instruction on how to change the home environment to support dietary goals. This pilot study examined whether it is feasible to change the household food environments of behavioral weight loss participants through the use of a commercially available grocery home delivery service. Methods Overweight participants (N = 28; BMI = 31.7 ± 3.6 kg/m2; 89.3% women, 47.9 ± 9.5 years were randomly assigned to 8-weeks of standard behavioral weight loss (SBT or to SBT plus home food delivery (SBT+Home. SBT+Home participants were instructed to do their household grocery shopping via an online service affiliated with a regional supermarket chain and were reimbursed for delivery charges. Results Compared to SBT, SBT+Home produced significantly greater reductions in the total number of foods in the home (p = .01 and number of foods that were high in fat (p = .002. While the groups did not differ in 8-week weight losses, within SBT+Home there was a trend for the number of home deliveries to be associated with weight loss (p = .08. Participants reported that the home delivery service was easy to use and that it helped decrease impulse purchases and lead to healthier choices; however, few planned to continue using the service after the study. Conclusion Encouraging weight loss participants to use a commercially available online grocery ordering and home delivery service reduces the overall number of food items in the home and decreases access to high-fat food choices. More research is needed to determine whether this is a viable strategy to strengthen stimulus control and improve weight loss outcomes.

Design Adults were randomly allocated to follow the Slim Fast Plan, Weight Watchers Pure Points Programme, Dr Atkins' New Diet Revolution, or Rosemary Conley's "Eat Yourself Slim" Diet & Fitness Plan. Setting A multi-centre randomised controlled trial. Subjects 293 adults, mean age 40.3 years and a mean BMI 31.7 (range 27–38 were allocated to follow one of the four diets or control group. Subjects completed a 7-day food and activity diary at baseline (prior to randomisation and after 2 months. Diet records were analysed for nutrient composition using WinDiets (research version. Results A significant shift in the macronutrient composition of the diet with concurrent alteration of the micronutrient profile was apparent with all diets. There was no evidence to suggest micronutrient deficiency in subjects on any of the dietary regimens. However, those sub-groups with higher needs for specific micronutrients, such as folate, iron or calcium may benefit from tailored dietary advice. Conclusion The diets tested all resulted in considerable macronutrient change and resulted in an energy deficit indicating dietary compliance. Health professionals and those working in community and public health should be reassured of the nutritional adequacy of the diets tested. Trial Registration Number NCT00327821

The aims of the present study were to investigate (1 whether body mass would be lost and body composition would change and (2 whether variables of anaerobic fitness prior to the intervention period would be related to loss of body mass and changes in body composition in overweight and obese children and adolescents. Methods: A total of 28 children and adolescents (19 boys, 9 girls attended an 8-week multicomponent inpatient program. Caloric intake was based on the subject's weight and a daily energy deficit of ~500 kcal was targeted. At the beginning and at the end of the program, variables of anaerobic fitness were assessed using Wingate tests. Body composition was measured before and after the program using dual-energy X-ray absorptiometry. Results: Body mass decreased by 11.4% ± 1.6% in boys and by 11.0% ± 2.8% in girls (P < 0.001. Fat mass decreased by 23.8% ± 6.1% in boys and by 21.5% ± 5.2% in girls (P < 0.001. The decrease in fat mass was associated with the decrease in body mass in boys (r = 0.54, P = 0.017 but not in girls (P > 0.05. The decrease in body mass and the decrease in fat mass were neither associated with overall energy expenditure nor with the energy deficit in both genders (P > 0.05.

This double blind controlled study aimed to investigate the effect of 8 weeks' daily consumption of 500 mL of natural orange juice enriched with 11.25 g of levan compared to the same amount of natural orange juice without levan on weight, gastrointestinal symptoms and metabolic profiles of 48 healthy volunteers. The statistical analyses compared between- and within-group findings at baseline, 4 weeks and study closure. The compared parameters were: weight, blood pressure, blood laboratory tests, daily number of defecations, scores of stool consistency, abdominal pain, bloating, gas, dyspepsia, vomiting and heartburn. Despite a higher fiber level recorded in the study group, there was no significant difference in the effect of the two kinds of juices on the studied parameters. Both juices decreased systolic and diastolic pressures, increased sodium level (within normal range), stool number, and bloating scores, and decreased gas scores. In conclusion, levan itself had no effect on weight, gastrointestinal symptoms or metabolic profile of healthy volunteers. Its possible effect on obese, hypertensive or hyperlipidemic patients should be investigated in further studies. PMID:22852055

    AIM: To estimate the standard liver weight for assessing adequacies of graft size in live donor liver transplantation and remnant liver in major hepatectomy for cancer.METHODS: In this study, anthropometric data of body weight and body height were tested for a correlation with liver weight in 159 live liver donors who underwent donor right hepatectomy including the middle hepatic vein. Liver weights were calculated from the right lobe graft weight obtained at the back table, divided by the proportion of the right lobe on the computed tomography.RESULTS: The subjects, all Chinese, had a mean age of 35.8 ± 10.5 years, and a female to male ratio of 118:41. The mean volume of the right lobe was 710.14 ±131.46 mL and occupied 64.55%±4.47% of the whole liver on computed tomography. Right lobe weighed 598.90±117.39 g and the estimated liver weight was 927.54 ± 168.78 g. When body weight and body height were subjected to multiple stepwise linear regression analysis, body height was found to be insignificant. Females of the same body weight had a slightly lower liver weight. A formula based on body weight and gender was derived: Estimated standard liver weight (g) = 218 + BW (kg) x 12.3 + genderx 51 (R2 = 0.48)(female = 0, male = 1). Based on the anthropometric data of these 159 subjects, liver weights were calculated using previously published formulae derived from studies on Caucasian, Japanese, Korean, and Chinese.All formulae overestimated liver weights compared to this formula. The Japanese formula overestimated the estimated standard liver weight (ESLW) for adults less than 60 kg.CONCLUSION: A formula applicable to Chinese males and females is available. A formula for individual races appears necessary.

    Quantitative trait locus (QTL) is a particular region of the genome containing one or more genes associated with economically important quantitative traits. This study was conducted to identify QTL regions for body weight and growth traits in purebred Korean native chicken (KNC). F1 samples (n = 595) were genotyped using 127 microsatellite markers and 8 single nucleotide polymorphisms that covered 2,616.1 centi Morgan (cM) of map length for 26 autosomal linkage groups. Body weight traits were measured every 2 weeks from hatch to 20 weeks of age. Weight of half carcass was also collected together with growth rate. A multipoint variance component linkage approach was used to identify QTLs for the body weight traits. Two significant QTLs for growth were identified on chicken chromosome 3 (GGA3) for growth 16 to18 weeks (logarithm of the odds [LOD] = 3.24, Nominal p value = 0.0001) and GGA4 for growth 6 to 8 weeks (LOD = 2.88, Nominal p value = 0.0003). Additionally, one significant QTL and three suggestive QTLs were detected for body weight traits in KNC; significant QTL for body weight at 4 weeks (LOD = 2.52, nominal p value = 0.0007) and suggestive QTL for 8 weeks (LOD = 1.96, Nominal p value = 0.0027) were detected on GGA4; QTLs were also detected for two different body weight traits: body weight at 16 weeks on GGA3 and body weight at 18 weeks on GGA19. Additionally, two suggestive QTLs for carcass weight were detected at 0 and 70 cM on GGA19. In conclusion, the current study identified several significant and suggestive QTLs that affect growth related traits in a unique resource pedigree in purebred KNC. This information will contribute to improving the body weight traits in native chicken breeds, especially for the Asian native chicken breeds. PMID:26732327

    2002-01-01

    Full Text Available Obesity is characterized by excessive body fat accumulation which may lead to serious health problems and complications. Body mass index is the most optimal parameter to evaluate the level of nutritional status and diagnose obesity. However, modern techniques studying body composition can more accurately determine whether the gain of body weight was on the account of body fat, lean body mass or total body water. If one's body mass index is in the range of normal values but the amount of body fat is above normal range, we talk about sarcopenic obesity. In order to evaluate presence of sarcopenic obesity, a group of 140 normal weight students of the Faculty of Medicine in Novi Sad were measured. Apart from standard anthropometrical parameters the amount of body fat was also determined by using the method of bioelectrical impedance analysis. Sarcopenic obesity was diagnosed in 25.71% of examined students. By using body mass index values this type of obesity cannot be diagnosed, and knowing that a higher amount of body fat in normal weight persons can lead to complications, especially metabolic, it is of great importance to evaluate the amount of body fat accurately.

  15. Selection for body weight in dairy cattle

    Koenen, E.P.C.

    2001-01-01

    This thesis deals with selection for body weight (BW) in dairy cattle. The economic efficiency of present breeding schemes might increase further when selection decisions also consider information on BW as BW relates to feed costs and revenues from beef production. However, the practical implementation of such a selection strategy is hindered by limited knowledge on procedures for data recording and genetic evaluation. The aim of this thesis was to study the possibilities and economic relevan...

    Body weight is regulated by the ability of hypothalamic neurons to orchestrate behavioral, endocrine and autonomic responses via afferent and efferent pathways to the brainstem and the periphery. Weight maintenance requires a balance between energy intake and energy expenditure. Although several components that participate in energy homeostasis have been identified, there is a need to know in more detail their actions as well as their interactions with environmental and psychosocial factors in the development of human obesity. In this review, we examine the role of systemic mediators such as leptin, ghrelin and insulin, which act in the central nervous system by activating or inhibiting neuropeptide Y, Agouti-related peptide protein, melanocortin, transcript related to cocaine and amphetamine, and others. As a result, modifications in energy homeostasis occur through regulation of appetite and energy expenditure. We also examine compensatory changes in the circulating levels of several peripheral hormones after diet-induced weight loss. PMID:26910628

  17. Soy isoflavones increase preprandial peptide YY (PYY, but have no effect on ghrelin and body weight in healthy postmenopausal women

    Full Text Available Abstract Background Soy isoflavones show structural and functional similarities to estradiol. Available data indicate that estradiol and estradiol-like components may interact with gut "satiety hormones" such as peptide YY (PYY and ghrelin, and thus influence body weight. In a randomized, double-blind, placebo-controlled, cross-over trial with 34 healthy postmenopausal women (59 ± 6 years, BMI: 24.7 ± 2.8 kg/m2, isoflavone-enriched cereal bars (50 mg isoflavones/day; genistein to daidzein ratio 2:1 or non-isoflavone-enriched control bars were consumed for 8 weeks (wash-out period: 8-weeks. Seventeen of the subjects were classified as equol producers. Plasma concentrations of ghrelin and PYY, as well as energy intake and body weight were measured at baseline and after four and eight weeks of each intervention arm. Results Body weight increased in both treatment periods (isoflavone: 0.40 ± 0.94 kg, P Conclusion Soy isoflavone supplementation for eight weeks did not significantly reduce energy intake or body weight, even though plasma PYY increased during isoflavone treatment. Ghrelin remained unaffected by isoflavone treatment. A larger and more rigorous appetite experiment might detect smaller differences in energy intake after isoflavone consumption. However, the results of the present study do not indicate that increased PYY has a major role in the regulation of body weight, at least in healthy postmenopausal women.

    2012-01-01

    Background: The objective of the current study was to assess the effects of royal jelly supple-mentation on body weight, total daily energy and macronutrients intakes in type2 diabetic fe-males. Methods: In this randomized clinical trial, fifty female volunteers with type2 diabetes were as-signed into the supplemented (n=25) and placebo (n=25) groups, given a daily dose of 1000 mg royal jelly soft gel or placebo, for 8 weeks, respectively. Before and after the intervention, body weight and height of subjects were measured and body mass index was calculated. Dietary intake of patients was assessed using 24-hour food recall questionnaire for three non consecutive days (including 1 weekend day) and analyzed with Nutritionist IV software. The normally distributed data were compared using paired and independent t-tests, where appropriate. Results: Royal jelly supplementation significantly (P<0.01) decreased the mean body weight (72.45±4.42 vs. 71.00±6.44 kg) while it increased insignificantly in placebo group (73.02±6.44 vs 73.52±6.80 kg). Royal jelly supplementation resulted in significant decrease of mean daily total energy (P<0.01) and carbohydrate (P<0.01) intakes, while in placebo group the mean daily total energy and fat intakes were increased significantly (P<0.05). Conclusion: Supplementation with royal jelly may be beneficial in weight management of di-abetic patients. PMID:24688939

  2. Weight status and body image perceptions in adolescents: current perspectives.

    Voelker, Dana K; Reel, Justine J; Greenleaf, Christy

    2015-01-01

    Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed. PMID:26347007

    Diffusion-weighted magnetic resonance imaging (DWI) provides information on the diffusivity of water molecules in the human body. Technological advances and the development of the concept of diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) have opened the path for routine clinical whole-body DWI. Whole-body DWI allows detection and characterization of both oncological and non-oncological lesions throughout the entire body. This article reviews the basic principles of DWI and the development of whole-body DWI, illustrates its potential clinical applications, and discusses its limitations and challenges.

    2013-06-01

    Many studies have shown that ingestion of high-fructose corn syrup (HFCS) may cause an increase in body weight and abdominal fat. We recently developed a new sweetener containing rare sugars (rare sugar syrup; RSS) by slight isomerization of HFCS. Here, the functional effects of RSS on body weight and abdominal fat, and biochemical parameters in Wistar rats were examined. Rats (n=30) were randomly divided into three groups and maintained for 8-weeks on starch, starch+HFCS (50:50), and starch+RSS (50:50) diets. Rats in the Starch and HFCS groups gained significantly more body weight and abdominal fat than the RSS group. Fasting serum insulin in the RSS group was significantly lower than in the Starch and HFCS groups, although serum glucose in the HFCS and RSS groups was significantly lower than that in the Starch group. Thus, the substitution of HFCS with RSS prevents obesity induced by the consumption of HFCS. PMID:23411176

  8. Body weight and beauty: the changing face of the ideal female body weight.

    Bonafini, B A; Pozzilli, P

    2011-01-01

    By observing the art of different eras, as well as the more recent existence of the media, it is obvious that there have been dramatic changes in what is considered a beautiful body. The ideal of female beauty has shifted from a symbol of fertility to one of mathematically calculated proportions. It has taken the form of an image responding to men's sexual desires. Nowadays there seems to be a tendency towards the destruction of the feminine, as androgynous fashion and appearance dominate our culture. The metamorphosis of the ideal woman follows the shifting role of women in society from mother and mistress to a career-orientated individual. Her depiction by artists across the centuries reveals this change in role and appearance that should be interpreted within the social and historical context of each era with its own theories of what constituted the ideal female body weight.

  10. Mechanisms of body weight fluctuations in Parkinson’s disease

    Andrea eKistner

    2014-06-01

    Full Text Available Typical body weight changes are known to occur in PD. Weight loss has been reported in early stages as well as in advanced disease and malnutrition may worsen the clinical state of the patient. On the other hand an increasing number of patients show weight gain under dopamine replacement therapy or after surgery. These weight changes are multifactorial and involve changes in energy expenditure, perturbation of homeostatic control, and eating behavior modulated by dopaminergic treatment. Comprehension of the different mechanisms contributing to body weight is a prerequisite for the management of body weight and nutritional state of an individual PD patient. This review summarizes the present knowledge and highlights the necessity of evaluation of body weight and related factors, as eating behavior, energy intake and expenditure in PD.

  11. EFFECT OF WEANER BODY WEIGHT ON GROWTH TRAITS OF RABBITS

    U.K. OKE

    2011-01-01

    Full Text Available Data from growth parameters and production traits of 108 ten-week old male rabbits comprising Newzealand white, Dutch and Chinchilla breeds collected over a period of 16 weeks were analysed in a 2- factor factorial in a randomised complete block (RCBD to determine their interrelationships and response to age and weaner body weight groupings as a step towards employing them in selection and breeding programme and predicting live body weight. Individual breeds were grouped into three categories of body weights of low (LBW, medium (MBW, and high (HBW, depending on the body weight range of each breed. The linear body parameters were characterised using Body weight (BW, Heart girth (HG, Shoulder to tail drop, Head to shoulder, Ear length and Tail length, while the Production traits studied were average Daily feed intake, Feed conversion efficiency and mortality. Results of the analysis evinced significant (P<0.01 effect of breed-body weight interaction on the Production traits and linear body parameters studied. High weaner body weight Chinchilla consumed more feed; converted feed to meat more efficiently, gained weight more rapidly and recorded no mortality. Regression and correlation studies revealed that any one of the linear body traits could predict the rabbit body, weight at 20 weeks of age. Trait combination revealed that Ear length Vs Height at withers (R2-0.944, Ear length Vs Heart girth (R2-0.969 and Heart girth (R2= 0.935 best contributed to the total variability in body weight of Newzealand white Dutch and chinchilla respectively.

    Full Text Available Diet, exercise, and pharmacological interventions have limited effects in counteracting the worldwide increase in pediatric body weight. Moreover, the promise that individualized drug design will work to induce weight loss appears to be exaggerated. We suggest that the reason for this limited success is that the cause of obesity has been misunderstood. Body weight is mainly under external control; our brain permits us to eat under most circumstances, and unless the financial or physical cost of food is high, eating and body weight increase by default. When energy-rich, inexpensive foods are continually available, people need external support to maintain a healthy body weight. Weight loss can thereby be achieved by continuous feedback on how much and how fast to eat on a computer screen.

  19. Lumbar spinal loads vary with body height and weight.

    Han, Kap-Soo; Rohlmann, Antonius; Zander, Thomas; Taylor, William R

    2013-07-01

    Knowledge about spinal loading is required for designing and preclinical testing of spinal implants. It is assumed that loading of the spine depends upon body weight and height, as well as on the spine level, but a direct measurement of the loading conditions throughout the spine is not yet possible. Here, computer models can allow an estimation of the forces and moments acting in the spine. The objective of the present study was to calculate spinal loads for different postures and activities at several levels of the thoracolumbar spine for various combinations of body height and weight. A validated musculoskeletal model, together with commercially available software (AnyBody Technology), were used to calculate the segmental loads acting on the centre of the upper endplate of the vertebrae T12 to L5. The body height was varied between 150 and 200 cm and the weight between 50 and 120 kg. The loads were determined for five standard static postures and three lifting tasks. The resultant forces and moments increased approximately linearly with increasing body weight. The body height had a nearly linear effect on the spinal loads, but in almost all loading cases, the effect on spinal loads was stronger for variation of body weight than of body height. Spinal loads generally increased from cranial to caudal. The presented data now allow the estimation of the spinal load during activities of daily living on a subject specific basis, if body height and weight are known. PMID:23040051

  1. The Effect of 8-week Aerobic and Concurrent (aerobic- resistance Exercise Training on Serum IL-6 Levels and Insulin Resistance in Type 2 Diabetic Patients

    P Yousefipoor

    2013-12-01

    Full Text Available Introductoin: Increased level of serum IL-6 is related to development of type 2 diabetes and insulin resistance. The American Diabetes Association and the American College of Sports Medicine recommend that combination of resistance and aerobic exercise is favorable for patients with type 2 diabetes. The purpose of this study was to investigate the effect of 8 weeks of aerobic exercise and concurrent (aerobic-resistance exercise on serum IL-6 Levels and insulin resistance in Type 2 Diabetic patients. Methods: In this study, from patients referring to Kermanshah Diabetes Association, 24 volunteers participated in the study as subjects and were divided into aerobic (n=8, concurrent (n=8, and control group (n=8 randomly. Training program for the aerobic group included 3 sessions of running per week with 60 to 80% maximal heart rate for 8 weeks but the concurrent group in addition to running, performed resistance training of major muscles groups. Before and after the intervention, body weight, BMI, fasting blood glucose, serum IL-6 and HOMA-IR were measured. Results: HOMA-IR and fasting blood glucose were significantly decreased in both training groups after intervention, but showed no significant changes in the control group. No significant changes were observed for serum IL-6 levels, body weight or BMI. Conclusion: performing 8 weeks of aerobic or concurrent training with improvement of insulin resistance and fasting blood glucose could be helpful for type 2 diabetic patients; however, it cannot significantly affect serum IL-6 levels, body weight, or BMI in these patients.

    Objective To compare the body weight reducing effect of two medium-chain fatty acids (MCFA), capric acid and caprylic acid, and the potential underlying mechanisms in C57BL/6J mice fed a high fat diet.Methods Obese C57BL/6J mice were developed on a high-fat diet containing 2% caprylic acid (C8:0), 2% capric acid (C10:0), or 2% oleic acid (C18:1). Body weight and diet intake were monitored twice a week. After 8 weeks of feeding, body fat composition and the protein or mRNA expression of lipolysis-related genes in the white adipose tissue (WAT) were analyzed.Results In the capric acid group, significant reductions were observed in body weight gain, Lee's index, BMI, and epididymal adipose tissue weight, while increased levels of adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), cyclic adenosine monophosphate (cAMP) and beta 3 adrenergic receptor (β3-AR) were found in the adipose tissue, compared to the oleic acid group. No significant differences in these parameters were found between caprylic acid and oleic acid groups.Conclusion Capric acid, but not caprylic acid, is effective in reducing body weight in obese C57BL/6J mice,possibly due to up-regulation of β3-AR, ATGL, and HSL in WAT.

    The objective of this study was to evaluate the use of hip height and width, body condition score, and relevant demographic information to predict body weight (BW) of dairy cows. Seven regression models were developed from data from 972 observations of 554 cows. Parity, hip height, hip width, and...... body condition score were consistently associated with BW. The coefficients of multiple determination varied from 80 to 89%. The number of significant terms and the parameter estimates of the models differed markedly among groups of cows. Apparently, these differences were due to breed and feeding...... regimen. Results from this study indicate that a reliable model for estimating BW of very different dairy cows maintained in a wide range of environments can be developed using body condition score, demographic information, and measurements of hip height and hip width. However, for management purposes...

    Gravity is a force that influences all living systems, and is often disregarded in the study of environment on growth and development. To assess the effect of gravity exposure on growth, immature rats (130-200 g) were evaluated during chronic altered gravity exposure and during transition between gravity fields. The effects of 14 days of spaceflight on body weight gain were evaluated (n=12) and compared to controls. Spaceflight did not affect weight gain. In 6 rats, the transition from spaceflight to 1 G showed a significant (p less than 0.05) post flight weight loss over 48 hr of 13 g compared to controls. Over subsequent days this loss was compensated for with no difference noted after 5 days. Exposure to hypergravity, 2 G for 16 days, was evaluated in groups of n=6 (Control; On Center Control (OCC); Centrifuged). With centrifugation or OCC there was a reduction in body weight within 24 hr. The OCC regained control weights within 13 days. The weight difference, 26 +/- 1 g, persisted with 2 G with no subsequent difference in weight gain over days 3-16 compared to controls; 3.7 +/- 0.1 versus 3.9 +/- 0.1 g/day respectively. Transition from centrifugation to 1 G resulted in a weight increase within 48 hours. Over 16 days the rate of gain was increased 3.1 +/- 0.1 g/day for centrifuge compared to 2.1 +/- 0.1 g/day for controls between Day 3 to 16. However, differences from control were still noted on Day 16. Transition from one gravity field to another causes acute changes in body weight. Transition to microgravity or 1 G, following the acute changes, results in adjustments to attain a normal weight. In hypergravity the acute reduction in body weight persist, but weight gain is normal. Transitioning from hypergravity to 1G results in an increased weight gain to compensate for the persistent reduction during exposure.

  8. The Association of Antidepressant Medication and Body Weight Gain.

    Sara Ranjbar

    2013-04-01

    Full Text Available Objective: To review the literature and discover which antidepressants are responsible for weight gain and then to discuss the areas with lack of adequate knowledge. Method: An electronic search was conducted through Medline, Pubmed, Cochrane library, and ScienceDirect. Forty nine empirical researches were identified and reviewed. Results: Amitriptyline, clomipramine, and mirtazapine have been associated with more weight gain induction in clinical studies, but not in animal-based studies. All TCAs have been reported to cause weight gain except protriptyline. MAOIs have been associated with weight gain. In SSRI group, citalopram and ecitalopram induce weight, yet mixed results exist for paroxetine and fluoxetine. Researches unanimously reported weight loss effect for bupropion. Some studies suggest contributing factors in the relationship of antidepressants with body weight changes including age, gender, base-line weights and treatment duration. Various results of different treatment durations have been reported in some cases but there are not continuous time-dependent studies for the influences of antidepressants on body weight changes. Conclusion: More studies are required to discover underlying mechanisms and the time-dependent effects of antidepressants on body weight changes.

  9. Weight status and the perception of body image in men

    Gardner RM

    2014-07-01

    Full Text Available Rick M Gardner Department of Psychology, University of Colorado Denver, Denver, CO, USA Abstract: Understanding the role of body size in relation to the accuracy of body image perception in men is an important topic because of the implications for avoiding and treating obesity, and it may serve as a potential diagnostic criterion for eating disorders. The early research on this topic produced mixed findings. About one-half of the early studies showed that obese men overestimated their body size, with the remaining half providing accurate estimates. Later, improvements in research technology and methodology provided a clearer indication of the role of weight status in body image perception. Research in our laboratory has also produced diverse findings, including that obese subjects sometimes overestimate their body size. However, when examining our findings across several studies, obese subjects had about the same level of accuracy in estimating their body size as normal-weight subjects. Studies in our laboratory also permitted the separation of sensory and nonsensory factors in body image perception. In all but one instance, no differences were found overall between the ability of obese and normal-weight subjects to detect overall changes in body size. Importantly, however, obese subjects are better at detecting changes in their body size when the image is distorted to be too thin as compared to too wide. Both obese and normal-weight men require about a 3%–7% change in the width of their body size in order to detect the change reliably. Correlations between a range of body mass index values and body size estimation accuracy indicated no relationship between these variables. Numerous studies in other laboratories asked men to place their body size into discrete categorizes, ranging from thin to obese. Researchers found that overweight and obese men underestimate their weight status, and that men are less accurate in their categorizations than

  10. Anatomic Dead Space Cannot Be Predicted by Body Weight

    Brewer, Lara M.; Orr, Joseph A.

    2007-01-01

    Anatomic, airway, or tracheal, dead space is the part of the tidal volume that does not participate in gas exchange. Knowledge of the size of the dead space is important for proper mechanical ventilation, especially if small tidal volumes are used. Respiratory and medical textbooks state that anatomic dead space can be estimated from the patient’s body weight. Specifically, these references suggest dead space can be predicted using a relationship of one milliliter per pound of body weight. Us...

  11. The influence of maternal body composition on birth weight.

    Farah, Nadine

    2012-02-01

    OBJECTIVE: To identify the maternal body composition parameters that independently influence birth weight. STUDY DESIGN: A longitudinal prospective observational study in a large university teaching hospital. One hundred and eighty-four non-diabetic caucasian women with a singleton pregnancy were studied. In early pregnancy maternal weight and height were measured digitally in a standardised way and the body mass index (BMI) was calculated. At 28 and 37 weeks\\' gestation maternal body composition was assessed using segmental multifrequency bioelectrical impedance analysis. At delivery the baby was weighed and the clinical details were recorded. RESULTS: Of the women studied, 29.2% were overweight and 34.8% were obese. Birth weight did not correlate with maternal weight or BMI in early pregnancy. Birth weight correlated with gestational weight gain (GWG) before the third trimester (r=0.163, p=0.027), but not with GWG in the third trimester. Birth weight correlated with maternal fat-free mass, and not fat mass at 28 and 37 weeks gestation. Birth weight did not correlate with increases in maternal fat and fat-free masses between 28 and 37 weeks. CONCLUSIONS: Contrary to previous reports, we found that early pregnancy maternal BMI in a non-diabetic population does not influence birth weight. Interestingly, it was the GWG before the third trimester and not the GWG in the third trimester that influenced birth weight. Our findings have implications for the design of future intervention studies aimed at optimising gestational weight gain and birth weight. CONDENSATION: Maternal fat-free mass and gestational weight gain both influence birth weight.

  12. Body weight gain after radioiodine therapy of hyperthyroidism

    Aim: Analysis and follow up of body weight after radioiodine therapy (RITh) of hyperthyroidism, since excessive weight gain is a common complaint among these patients. Methods: Therapy and body weight related data of 100 consecutive RITh-patients were retrospectively analysed from the time before up to three years after RITh. All patients suffered from hyperthyroidism (Graves' disease or autonomy), but were adjusted to euthyroid levels after RITh. Patients' data were compared to a control group of 48 euthyroid patients out of the same ambulance and during the same time scale. Results: All patients (RITh and controls) gained weight over the time. There was no statistically significant difference in BMI development over three years between RITh-patients and controls (5.5% resp. 4.9% increase). In the first year after RITh, weight gain of the RITh patients was higher indeed, but lower in the follow up, resulting in the same range of weight gain after three years as the controls. Besides that women showed a slightly higher increase of BMI than men, and so did younger patients compared to elder as well as patients with overweight already before RITh. Conclusions: An initially distinct increase of body weight after RITh of hyperthyroidism is mainly a compensation of pretherapeutic weight loss due to hyperthyroidism. Presupposing adequate euthyroid adjustment of thyroid metabolism after therapy, RITh is not responsible for later weight gain and adipositas. (orig.)

    2012-08-01

    Full Text Available Study was conducted in the regency of Minahasa to estimate horse live weight using its chest girth, body length and body volume formula (cylinder volume formula represented by animal chest girth and body length dimensions, particularly focused in Minahasa local horses. Data on animal live weight (LW, body length (BL, chest girth (CG and body volume were collected from 221 stallions kept by traditional household farmers. Animal body volume was calculated using cylinder volume formula with CG and BL as the components of its formula. Regression analysis was carried out for LW with all the linear body measurements. The data were classified on the basis of age. Age significantly (P0.05. Animal live weight was predicted by simple regression models using dependent variable (Y of the animal live weight and independent variable (X of the animal body measurement, either body length, chest girth, or body volume. The correlations between all pairs of measurements were highly significant (P<0.01 for all age groups. Regression analysis showed that live weight could be predicted accurately from body volume (R2= 0.92 and chest girth (R2= 0.90. Simple regression model that can be recommended to predict horse live weight based on body volume with their age groups ranging from 3 to ≥10 years old was as follow: Live weight (kg= 5.044 + 1.87088 body volume (liters. The analyses of data on horse chest girth, body length and body volume formula provided quantitative measure of body size and shape that were desirable, as they enable genetic parameters for these traits to be estimated and also included in breeding programs.

    2014-01-01

    Full Text Available Growing consciousness about ideal body image leads to dietary modifications and consequent eating disorders among girls in developing countries like India. The present study aims to (i assess the prevalence of body weight consciousness and related behaviours among a group of adolescent girls; (ii assess the sociodemographic correlates of weight related behaviours; and (iii compare weight related behaviours of the girls of two religious groups residing in Howrah. The study is the outcome of a cross-sectional school based survey involving 280 (159 Hindu and 121 Muslim girls from standards 8 to 11. Significant differences exist between two religious groups with respect to their family size, socioeconomic profile, and media exposures (in terms of watching television. Consciousness about body weight among girls shows significant difference with respect to religion, family size (χ2=64.77, father’s occupation (χ2=60.28, level of education of both the parents, and media exposure (P<0.05. Consciousness about body weight drives them to adopt several behavioural measures like calorie restriction, food avoidance, and dieting. Sociodemographic correlates of all these behaviours have been analyzed. The study documents that concern over body image and weight loss is quite important among these urban girls.

  15. Weight self-regulation process in adolescence: the relationship between control weight attitudes, behaviors and body weight status

    Jordi ePich

    2015-05-01

    Full Text Available Adolescents’ self-control weight behaviors were assessed (n= 1961; 12-17 years old; 2007-2008 in the Balearic Islands, Spain. The study analyzed the relationships between body weight status, body image and self-weight concern, and actual attempts to lose weight by restrained eating and/or increased exercising. In terms of regulatory focus theory (RFT, we considered that efforts to lose or to maintain weight (successful or failed would be motivated either by a promotion focus (to show an attractive body, a prevention focus (to avoid social rejection of fatness, or both. Results showed that 41% of overweight boys and 25% of obese boys stated that they had never made any attempt to lose weight, and 13% and 4% in females. Around half of overweight boys and around a quarter of obese boys stated that they were Not at all concerned about weight gain, and girls’ percentages decreased to 13% and 11% respectively. By contrast 57% of normal weight girls monitored their weight and stated that they had tried to slim at least once. Weight self-regulation in females attempted to combine diet and exercise, while boys relied almost exclusively on exercise. Apparent lack of consciousness of body weight status among overweight boys, and more important, subsequent absence of behaviors to reduce their weight clearly challenges efforts to prevent obesity. We argue that several causes may be involved in this outcome, including unconscious emotional (self-defense and cognitive (dissonance mechanisms driven by perceived social stigmatization of obesity. The active participation of social values of male and female body image (strong vs. pretty and the existence of social habituation to overweight are suggested. A better knowledge of psychosocial mechanisms underlying adolescent weight self-control may improve obesity epidemics.

  17. Food shopping and weight concern. Balancing consumer and body normality

    Nielsen, Annemette; Holm, Lotte

    2014-01-01

    The desire to achieve a normal, culturally acceptable body is often seen as the main driver of food-consumption practices adopted by individuals who are concerned about their body weight. In social research into weight management self-control is therefore often a central theme. Turning the focus...... towards practices and values related to food shopping, this study adds to our understanding of central features in perceptions of normality among people with weight concerns. In a qualitative study 25 people who participated in a dietary intervention trial in Denmark were interviewed and five people were......, practices and experiences of controlling food intake. The paper suggests that freedom and control are composite and complementary ideals of normality for people with weight concerns. On the basis of this insight, the authors discuss the contribution the paper makes to existing studies of weight management...

  19. Effects of dietary creatine supplementation for 8 weeks on neuromuscular coordination and learning in male albino mouse following neonatal hypoxic ischemic insult.

    Iqbal, Shahid; Ali, Muhammad; Akbar, Atif; Iqbal, Furhan

    2015-05-01

    Creatine monohydrate (Cr) is a dietary supplement known to improve cognitive functions and has positive therapeutic results under various clinical conditions. The aim of this study was to determine the effect of 2 % Cr supplementation on learning, memory formation, neuromuscular coordination, exploratory and locomotory in male albino mice following hypoxic ischemic insult. At postnatal day, 10 male albino mice pups were subjected to right common carotid artery ligation followed by 8 % hypoxia for 25 min. On postnatal day 20, male mice were separated from the litter and divided into two groups on the basis of special diet supplementation. One group was supplemented with 2 % Cr in diet while the other group was raised on ordinary rodent chow for 8 weeks. Behavioral observations were made during rota rod, open field and Morris water maze test for both treatments. It was observed that supplementation with 2 % Cr for 8 weeks following neonatal brain damage resulted in enhanced muscular strength, neuromuscular coordination and improved body weight. In Morris water maze test, it was observed that Cr supplementation significantly improved mean swimming speed and mice on 2 % Cr diet covered more distance but the spatial memory was not improved significantly following hypoxia ischemia encephalopathy (HIE). Open field parameters and percentage of infarct volume remained unaffected following Cr supplementation. We concluded that 2 % dietary Cr supplementation has a potential to improve the muscle strength and body weight in male albino mice following (HIE) and should be considered for the treatment of neurological ailments.

  2. Genetic parameters of body weight and prolificacy in pigeons

    Beaumont Catherine

    2000-07-01

    Full Text Available Abstract Genetic parameters of body weight at weaning and of prolificacy were estimated in three commercial lines of pigeons selected by BLUP (Best Linear Unbiased Prediction on both traits. The model of analysis took into account the direct genetic effects for both traits and the effect of parental permanent environment for body weight. Depending on the line considered, body weight varied from 556.7 g to 647.6 g and prolificacy ranged from 12.5 to 16.8 pigeons weaned per couple of parents per year. Heritability of body weight was high, varying between 0.46 and 0.60, and permanent environment was responsible for 6% to 9% of the total variability. On the contrary, prolificacy was poorly heritable (0.04 to 0.12. They were highly and negatively correlated (-0.77 to -0.82. Body weight showed significant genetic trends in lines B and C. No significant genetic difference could be observed between males and females for both traits.

  4. Modeling of daily body weights and body weight changes of Nordic Red cows.

    Mäntysaari, P; Mäntysaari, E A

    2015-10-01

    Increased availability of automated weighing systems have made it possible to record massive amounts of body weight (BW) data in a short time. If the BW measurement is unbiased, the changes in BW reflect the energy status of the cow and can be used for management or breeding purposes. The usefulness of the BW data depends on the reliability of the measures. The noise in BW measurements can be smoothed by fitting a parametric or time series model into the BW measurements. This study examined the accuracy of different models to predict BW of the cows based on daily BW measurements and investigated the usefulness of modeling in increasing the value of BW measurements as management and breeding tools. Data included daily BW measurements, production, and intake from 230 Nordic Red dairy cows. The BW of the cows was recorded twice a day on their return from milking. In total, the data included 50,594 daily observations with 98,418 BW measurements. A clear diurnal change was present in the BW of the cows even if they had feed available 24 h. The daily average BW were used in the modeling. Five different models were tested: (1) a cow-wise fixed second-order polynomial regression model (FiX) including the exponential Wilmink term, (2) a random regression model with fixed and random animal lactation stage functions (MiX), (3) MiX with 13 periods of weighing added (PER), (4) natural cubic smoothing splines with 8 equally spaced knots (SPk8), and (5) spline model with no restriction on knots but a smoothing parameter corresponding to a fit of 5 degrees of freedom (SPdf5). In the original measured BW data, the within-animal variation was 6.4% of the total variance. Modeling decreased the within animal variation to levels of 2.9 to 5.1%. The smallest day-to-day variation and thereafter highest day-to-day repeatabilities were with PER and MiX models. The usability of modeled BW as energy balance (EB) indicator were evaluated by estimating relationships between EB, or EB

    Hile, M E; Hintz, H F; Erb, H N

    1997-12-01

    Accurate estimates of body weight can be useful in the evaluations of feeding programs, nutritional status and general health, and in calculation of dose levels (such as for anesthesia)-thus providing a valuable tool for captive elephant management. We used body measurements of 75 Asian elephants (Elephas maximus) to predict body weight. Weight, heart girth, height at the withers, body length, and foot-pad circumference were measured. All possible linear regressions of weight on one, two, three, or four body measurements were calculated. The highest correlation with a single measurement was that between heart girth and weight (R2 = 0.90). The data were also divided into age groups (1-13, 18-28, 29-39, and 40-57 yr), and all possible linear regressions were calculated for each group (there were no elephants aged 14-17 yr). Adding body length or pad circumference to heart girth resulted in a slight increase in R2. We conclude that body weight in Asian elephants can be predicted from body measurements and that heart girth is the best predictor. A second body measurement might improve predictive accuracy for some age groups. PMID:9523637

  6. Energy intake and body weight in ovo-lacto vegetarians.

    Levin, N; Rattan, J; Gilat, T

    1986-08-01

    Vegetarians have a lower body weight than omnivores. In this study the relationship between the weight/height ratio and food consumption was evaluated in 92 ovo-lacto vegetarians and 113 omnivores in Israel. The average weight of the vegetarians was significantly lower than that of the omnivores (60.8 kg vs. 69.1 kg), even though the vegetarian diet supplied a significantly higher amount of calories than the nonvegetarian diet (3,030.5 cal/day vs. 2,626.8 cal/day). Consumption of fat was similar in both groups. Carbohydrate consumption was higher in the vegetarians while protein consumption was lower. The prevalence of obesity was significantly lower in the vegetarian group (5.4%) as compared to 19.5% among the omnivores. The lower body weight of vegetarians despite a higher caloric intake is of considerable interest. PMID:3760524

  7. [Etiological and exacerbation factors for COPD. Body weight loss].

    Yokoyama, Akihito

    2016-05-01

    Hunger or malnutrition is not only a historical issue but also a current problem worldwide. Biological responses to hunger are evolutionary prepared in our body, including energy generation by degradation of body proteins. Extreme weight loss (malnutrition) can cause air space enlargement in human and rodents. However, the changes in rodents could be reversible, since refeeding could repair the pathology. On the other hand, weight loss is a common feature in patients with more severe COPD. Complex factors, such as increased energy consumption, decreased food uptake by low grade inflammation, socio-economic factors and so on, are involved in weight loss. Weight loss in patients with COPD also increases the risk of exacerbation, hospitalization, and death. PMID:27254941

    Xu, Baoji; Xie, Xiangyang

    2016-05-01

    Energy balance - that is, the relationship between energy intake and energy expenditure - is regulated by a complex interplay of hormones, brain circuits and peripheral tissues. Leptin is an adipocyte-derived cytokine that suppresses appetite and increases energy expenditure. Ironically, obese individuals have high levels of plasma leptin and are resistant to leptin treatment. Neurotrophic factors, particularly ciliary neurotrophic factor (CNTF) and brain-derived neurotrophic factor (BDNF), are also important for the control of body weight. CNTF can overcome leptin resistance in order to reduce body weight, although CNTF and leptin activate similar signalling cascades. Mutations in the gene encoding BDNF lead to insatiable appetite and severe obesity. PMID:27052383

  11. Social Stress at Work and Change in Women's Body Weight

    Kottwitz, Maria Undine; Grebner, Simone Irmgard; Semmer, Norbert K.; Tschan, Franziska; ELFERING, Achim

    2014-01-01

    Social stressors at work (such as conflict or animosities) imply disrespect or a lack of appreciation and thus a threat to self. Stress induced by this offence to self might result, over time, in a change in body weight. The current study investigated the impact of changing working conditions —specifically social stressors, demands, and control at work— on women’s change in weighted Body-Mass-Index over the course of a year. Fifty-seven women in their first year of occupational life participa...

    Endocrine disrupting chemicals with estrogenic activity play an important role as obesogens. However, studies investigating the most potent natural estrogen, estradiol-17β (E2), at low dose are lacking. We examined endocrine and physiological parameters in gilts receiving distinct concentrations of E2 during pregnancy. We then investigated whether adverse effects prevail in progeny due to a potential endocrine disruption. E2 was orally applied to gilts during the entire period of pregnancy. The concentrations represented a daily consumption at the recommended ADI level (0.05 μg/kg body weight/day), at the NOEL (10 μg/kg body weight/day) and at a high dosage (1000 μg/kg body weight/day). Plasma hormone concentrations were determined using enzyme immuno assays. Offspring body fat was assessed by dual-energy X-ray absorptiometry scanning. In treated gilts receiving 1000 μg E2/kg body weight/day we found significantly elevated plasma E2 levels during pregnancy, paralleled by an increased weight gain. While offspring showed similar weight at birth, piglets exhibited a significant reduction in weight at weaning even though their mothers had only received 0.05 μg E2/kg body weight/day. At 8 weeks of age, specifically males showed a significant increase in overall body fat percentage. In conclusion, prenatal exposure to low doses of E2 affected pig offspring development in terms of body weight and composition. In line with findings from other obesogens, our data suggest a programming effect during pregnancy for E2 causative for the depicted phenotypes. Therefore, E2 exposure may imply a possible contribution to childhood obesity. -- Highlights: ► We investigate the potential role of estradiol-17β (E2) as an obesogen. ► We orally apply E2 at the ADI, NOEL and a high dose to gilts during pregnancy. ► Offspring weight is similar at birth but reduced at weaning even after ADI treatment. ► Male offspring only exhibit an increase in overall body fat percentage

    2012-01-01

    Full Text Available A study, to develop regression models for prediction of body weight from other linear body measurements, was conducted in Esite, Farta and Lai-Gaint districts of South Gondar, Amhara region. Records on body weight (BW and other linear body measurements (Body Length (BL, Wither Height (WH, Chest Girth (CH, Pelvic Width (PW and Ear Length (EL were taken from 941 sheep. Non-linear, simple linear and multiple linear regression models were developed using Statistical Package for Social Sciences (SPSS version 12.0. For the multiple linear regressions, step-wise regression procedures were used. Predicting models were developed for different age, sex and for the pool. Positive and significant (P<0.01 correlations were observed between body weight and linear body measurements for all sex and age groups. Among the four linear body measurements, heart girth had the highest correlation coefficient (except ear length in all age and sex groups which is followed by body length, height at wither and pelvic width. Heart girth was the first variable to explain more variation than other variables in both sex and age groups. The models developed had a coefficient of determination of 0.26 to 0.89; the highest coefficient of determination was depicted for male while the lowest was for dentition groups having two permanent incisors. Regression models in general were poor in explaining weight for the dentition groups above one pair of permanent incisors. Heart girth alone was able to estimate weight with a coefficient of determination of 0.77, for both sexes and the pool. The coefficient of determination of the fitted equations (in general decreased as the age of sheep advances indicating that the fitted equations can predict weight for younger sheep with better accuracy than for older ones. In general, much of the variation in weight was explained when many traits were included in the model. However, for ease of use and to avoid complexity at field condition, it is

    2006-01-01

    Full Text Available Data concerning body measurements, milk yield and body weights data were analysed on 101 of Holstein Friesian cows. Phenotypic correlations indicated positive significant relations between estimated feed efficiency (EFE and milk yield as well as 4 % fat corrected milk yield, and between body measurements and milk yield. However, negative correlations were found between the EFE and body measurements indicating that the taller, longer, deeper and especially heavier cows were not to be efficient as smaller cows

  17. Anorexia nervosa at normal body weight!--The abnormal normal weight control syndrome.

    Crisp, A H

    1981-01-01

    Disgust with "fatness" and a consequent preoccupation with body weight, coupled with an inability to reduce it to or sustain it at the desired low level, characterizes the abnormal normal weight control syndrome. Individuals remain sexually active in a biological sense and often also socially. Indeed their sexual behaviour may be as impulse ridden as is their eating behaviour, which often comprises phases of massive bingeing coupled with vomiting and/or purgation. The syndrome is unlike frank anorexia nervosa in that the latter involves a regression to a position of phobic avoidance of normal body weight and consequent low body weight control with inhibition of both biological and social sexual activity. In abnormal normal weight control there is a strong and sometimes desperate hedonistic and extrovert element that will often not be denied so long as body weight does not get too low. Individuals nevertheless feel desperately "out of control" and insecure beneath their bravura. The syndrome is much more common in females than in males. There is a clinical overlap with anorexia nervosa and obesity in many cases as the disorder evolves. Depression, stealing, drug dependence (including alcohol) and acute self-poisoning and self-mutilation are common complications. Clinic cases probably only represent the tip of the iceberg of the much more widespread morbidity within the general population. Like anorexia nervosa and for the same reasons the disorder is probably more common than it used to be. PMID:7309391

    Excess body weight leads to a variety of metabolic changes and increases the risk for cardiovascular diseases (CVD) in adulthood. The objective of this study was to investigate the presence of risk markers for CVD among Brazilian adolescents of normal weight and with excess body weight. The markers included blood pressure, C-reactive protein, homocysteine, tumor necrosis factor alpha, fibrinogen, fasting insulin and glucose, homeostasis model assessment of insulin resistance (HOMA-IR), leptin, total cholesterol, low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), and triglycerides. We calculated odds ratios (OR) using logistic regression and adjusted for potential confounders such as age, sex, physical activity, and socioeconomic background. Compared with normal weight subjects, overweight/obese adolescents were more likely to have higher systolic blood pressure (OR = 3.49, p overweight increased to 11.09 (95% CI: 4.05-30.35). In conclusion, excess body weight in adolescents exhibits strong associations with several markers that are established as causes of CVD in adults. This observation stresses the importance of primary prevention and of maintaining a healthy body weight throughout adolescence to reduce the global burden of CVD. PMID:27227571

    2015-08-01

    Pollen is offered as alternative or supplementary food for predacious mites; however, it may vary in its nutritional value. Body weight appears a representative parameter to describe food quality. Thus, we assessed the body weight for adults of the generalist mites Amblyseius swirskii, Amblydromalus limonicus, and Neoseiulus cucumeris reared on 22, 12, and 6 pollen species, respectively. In addition, A. swirskii and A. limonicus was reared on codling moth eggs. In all mite species, female body weight was higher than that of males, ranging between 4.33 and 8.18 µg for A. swirskii, 2.56-6.53 µg for A. limonicus, and 4.66-5.92 µg for N. cucumeris. Male body weight ranged between 1.78 and 3.28 µg, 1.37-3.06 µg, and 2.73-3.03 µg, respectively. Nutritional quality of pollen was neither consistent among the mite species nor among sex, revealing superior quality of Quercus macranthera pollen for females of A. swirskii and Tulipa gesneriana pollen for males, Alnus incana pollen for females of A. limonicus and Aesculus hippocastanum pollen for males, and Ae. hippocastanum pollen for both sexes of N. cucumeris. The results are discussed against the background of known or putative pollen chemistry and mite's nutritional physiology. PMID:26014648

  2. Diffusion-weighted imaging in pediatric body magnetic resonance imaging.

    Chavhan, Govind B; Caro-Dominguez, Pablo

    2016-05-01

    Diffusion-weighted MRI is being increasingly used in pediatric body imaging. Its role is still emerging. It is used for detection of tumors and abscesses, differentiation of benign and malignant tumors, and detection of inflamed bowel segments in inflammatory bowel disease in children. It holds great promise in the assessment of therapy response in body tumors, with apparent diffusion coefficient (ADC) value as a potential biomarker. Significant overlap of ADC values of benign and malignant processes and less reproducibility of ADC measurements are hampering its widespread use in clinical practice. With standardization of the technique, diffusion-weighted imaging (DWI) is likely to be used more frequently in clinical practice. We discuss the principles and technique of DWI, selection of b value, qualitative and quantitative assessment, and current status of DWI in evaluation of disease processes in the pediatric body.

    2014-01-01

    Full Text Available Objective: to evaluate the relationship between body composition of preschool children suffering from excess weight and birth weight (BW. Methods: probabilistic sample, by conglomerates, with 17 daycare centers (of a total of 59 composing a final sample of 479 children. We used Z-score of Body Mass Index (zBMI ≥ +1 and ≥ +2, respectively, to identify preschool children with risk of overweight and excess weight (overweight or obesity. The arm muscle area (AMA and the arm fat area (AFA were estimated from measurements of arm circumference, triceps skin fold thickness. Results: the prevalence of risk of overweight was 22.9% (n=110 and excess weight was 9.3% (n=44. The risk of overweight and excess weight in children did not show correlation between BW and AFA, but it did with adjusted arm muscle area (AMAa (rp= 0.21; p= 0.0107. The analysis of the group with excess weight alone also showed a positive correlation between BW and AMAa (rp= 0.42; p= 0.0047. Conclusion: among overweight children, lower BW is associated with a lower arm muscle area in early preschool age, regardless of the fat arm area presented by them.

  4. Elite athletes in aesthetic and Olympic weight-class sports and the challenge of body weight and body compositions.

    Sundgot-Borgen, Jorunn; Garthe, Ina

    2011-01-01

    The use of dieting, rapid weight loss, and frequent weight fluctuation among athletes competing in weight-class and leanness sports have been considered a problem for years, but the extent of the problem and the health and performance consequences have yet to be fully examined. Most studies examining these issues have had weak methodology. However, results from this review indicate that a high proportion of athletes are using extreme weight-control methods and that the rules of some sports might be associated with the risk of continuous dieting, energy deficit, and/or use of extreme weight-loss methods that can be detrimental to health and performance. Thus, preventive strategies are justified for medical as well as performance reasons. The most urgent needs are: (1) to develop sport-specific educational programmes for athletic trainers, coaches, and athletes; (2) modifications to regulations; and (3) research related to minimum percentage body fat and judging patterns.

  5. Social stress at work and change in women's body weight.

    Kottwitz, Maria U; Grebner, Simone; Semmer, Norbert K; Tschan, Franziska; Elfering, Achim

    2014-01-01

    Social stressors at work (such as conflict or animosities) imply disrespect or a lack of appreciation and thus a threat to self. Stress induced by this offence to self might result, over time, in a change in body weight. The current study investigated the impact of changing working conditions--specifically social stressors, demands, and control at work--on women's change in weighted Body-Mass-Index over the course of a year. Fifty-seven women in their first year of occupational life participated at baseline and thirty-eight at follow-up. Working conditions were assessed by self-reports and observer-ratings. Body-Mass-Index at baseline and change in Body-Mass-Index one year later were regressed on self-reported social stressors as well as observed work stressors, observed job control, and their interaction. Seen individually, social stressors at work predicted Body-Mass-Index. Moreover, increase in social stressors and decrease of job control during the first year of occupational life predicted increase in Body-Mass-Index. Work redesign that reduces social stressors at work and increases job control could help to prevent obesity epidemic. PMID:24429516

  7. Unconventional dose administrations: modifications of body and small intestine weights

    The modifications of body and small intestine weight were analyzed after abdominal irradiation in rats. Different doses were administered in single sessions, in two equal fractions with different splits, in multiple daily fractionations, varying the amount of the dose and the intervals among fractions. The results show that body weight gradually decreased after irradiation and only after many days it returned to control levels. Small intestine weight decreased starting from early intervals, and a rapid increase over controls was observed at 5 days. A return to control levels was reaches later. Multiple-daily-fractionation (MDF) irradiation with 12 Gy (1200 rad) produced modifications less evident than the same dose administered in single session and appeared more similar to those observed after 6 or 8 Gy, according to the different splits used. The more marked the damage the lower the interval between fractions when a total dose of 12 Gy was administered in two fractions. The modifications after 6 Gy MDF were less marked than after a single session of the same magnitude, both in body and small-intestinal weight. In conclusion the MDF used in these experiments produced a damage very easily recovered by the organism in spite of the short time of dose administration. (orig.)

    2009-01-01

    To assess the reproducibility of whole-body diffusion weighted imaging (WB-DWI) technique in healthy volunteers under normal breathing with background body signal suppression. Methods WB-DWI was performed on 32 healthy volunteers twice within two-week period using short TI inversion-recovery diffusion-weighted echo-planar imaging sequence and built-in body coil. The volunteers were scanned across six stations continuously covering the entire body from the head to the feet under normal breathing. The bone apparent diffusion coefficient (ADC) and exponential ADC (eADC) of regions of interest (ROIs) were measured. We analyzed correlation of the results using paired-t-test to assess the reproducibility of the WB-DWl technique.Results We were successful in collecting and analyzing data of 64 WB-DWI images. There was no significant difference in bone ADC and eADC of 824 ROIs between the paired observers and paired scans (P>0.05). Most of the images from all stations were of diagnostic quality.Conclusion The measurements of bone ADC and eADC have good reproducibility. WB-DWI technique under normal breathing with background body signal suppression is adequate.

  11. Body weight concerns and antifat attitude in iranian children

    Saideh Garousi

    2014-01-01

    Full Text Available Background: There is increasing evidence that children are showing body image issues in recent years. Body image disturbances in childhood must be taken seriously. The thin ideal is becoming more prominent in Asian countries; however, there is little research examining how this issue affects Iranian children. This study explores body weight concerns and associated factors among children in Iranian elementary schools. Methods: This study was conducted in 500 elementary schools. An assessment of body image and antifat attitudes was undertaken using the figure rating scale. In addition, body mass index (BMI and demographic variables were assessed. Results: Nearly, 27.4% of children were underweight, and 13.3% were obese. There was a significant difference between the mean score of body dissatisfaction (BD between boys and girls (P < 0.05. There were no differences between BD and education of parents, age, and academic grades. In girls, antifat attitudes were significantly related to BMI. Conclusions: The results of this study demonstrate the paramount importance of undertaking further research in order to identify the predictive factors of body concerns and its consequences among Iranian children. In addition, researchers must plan prevention and educational program for these children.

  12. Body image, body dissatisfaction and weight status in south asian children: a cross-sectional study

    Duda Joan L

    2011-01-01

    Full Text Available Abstract Background Childhood obesity is a continuing problem in the UK and South Asian children represent a group that are particularly vulnerable to its health consequences. The relationship between body dissatisfaction and obesity is well documented in older children and adults, but is less clear in young children, particularly South Asians. A better understanding of this relationship in young South Asian children will inform the design and delivery of obesity intervention programmes. The aim of this study is to describe body image size perception and dissatisfaction, and their relationship to weight status in primary school aged UK South Asian children. Methods Objective measures of height and weight were undertaken on 574 predominantly South Asian children aged 5-7 (296 boys and 278 girls. BMI z-scores, and weight status (underweight, healthy weight, overweight or obese were calculated based on the UK 1990 BMI reference charts. Figure rating scales were used to assess perceived body image size (asking children to identify their perceived body size and dissatisfaction (difference between perceived current and ideal body size. The relationship between these and weight status were examined using multivariate analyses. Results Perceived body image size was positively associated with weight status (partial regression coefficient for overweight/obese vs. non-overweight/obese was 0.63 (95% CI 0.26-0.99 and for BMI z-score was 0.21 (95% CI 0.10-0.31, adjusted for sex, age and ethnicity. Body dissatisfaction was also associated with weight status, with overweight and obese children more likely to select thinner ideal body size than healthy weight children (adjusted partial regression coefficient for overweight/obese vs. non-overweight/obese was 1.47 (95% CI 0.99-1.96 and for BMI z-score was 0.54 (95% CI 0.40-0.67. Conclusions Awareness of body image size and increasing body dissatisfaction with higher weight status is established at a young age in

  15. Why do girls watch their weight? Sociocultural and interpersonal influences on body image and weight watching

    Metka Kuhar

    2003-06-01

    Full Text Available Body dissatisfaction, importance of thinness, dieting behaviour, and weight watching were examined through discussions with 34 girls in five focus groups and with a questionnaire survey on the sample of 184 girls. The article emphasis is on sociocultural and interpersonal influences on girl's body images and eating practices. Quantitative and qualitative results point to fashion and media as the strongest pressures to be thin for subjects. Family members and peers are beside magazines, TV programmes and numbers of clothes important source of message about the importance and attainability of thinness. Some respondents reported direct pressures to diet from friends and parents but indirect social influences were more common. These influences included social comparison, teasing, criticizing. A few girls live in a subculture of intense weight and body-shape concern that places them at risk for disordered eating behaviour.

  16. Neuropeptide Y level in paraventricular nucleus of experimental diabetic rats: correlation with sympathetic activity and body weight

    Pallab K Ganguly

    2010-09-01

    Full Text Available Pallab K GangulyCollege of Medicine, Alfaisal University, Riyadh, Kingdom of Saudi ArabiaAbstract: Neuropeptide Y (NPY, colocalized with norepinephrine neuron, is known to modulate sympathetic activity and feeding behavior. Although experimental type 1 diabetes has increased sympathetic activity at the early part of the disease process, little effort was made so far to understand the correlation between NPY level in the hypothalamus and sympathetic activity in diabetes. Male Sprague Dawley rats were made diabetic by a single injection of streptozotocin (65 mg/kg body weight, IV. The animals were then studied after 2, 4, and 8 weeks. Control animals received only citrate vehicle. In an effort to clarify the modulatory effect of NPY at the early stage of diabetes, the paraventricular nucleus (PVN of hypothalamus was sampled by microdialysis for NPY and norepinephrine level. While NPY level was increased immediately within 2 weeks (along with feeding behavior, norepinephrine level was increased only after 8 weeks following injection of streptozotocin. The animals lost significant weight. These results are interpreted to mean that a strong correlation exists between the feeding behavior and NPY level in PVN. Since NPY is known to inhibit sympathetic activity it is possible that NPY receptors are down-regulated following diabetes. The higher level of norepinephrine indicating higher sympathetic activity did not allow the animals to gain weight. In addition, controversy exists regarding pleiotropic activities of NPY related to the feeding behavior of these animals.Keywords: streptozotocin-induced diabetes, increased sympathetic activity, feeding behavior, down-regulation of NPY receptors

    2006-01-01

    The purpose of this study was to identify new indexes of body composition that characterize the normal weight obese (NWO) women. We measured body composition by dual energy x-ray absorptiometry (DXA) and resting metabolic rate (RMR) by indirect calorimetry in a cohort of seventy-five healthy Italian women, subdivided into three groups (nonobese/controls, NWO, preobese-obese women). Despite a normal body mass index (BMI), the NWO women have a higher body fat mass percentage (FAT %) (38.99 +/- 6.03) associated to a significant (p = 0.02) lower amount of lean mass of legs (12.24 +/- 1.31) and lean mass of left leg (6.07 +/- 0.64) with respect to the control group. The NWO group showed a significant (p = 0.043) lower RMR (1201.25 +/- 349.02) in comparison with nonobese and preobese-obese women. To classify NWO individuals among general population, we identified three significant body composition indexes: abdominal index, leg index and trunk index.

    We conducted a retrospective study to determine the association between maternal body mass index and pregnancy weight gain with low birth weight newborns (LBWN) at Phrapokklao Hospital in eastern Thailand. We evaluated the files of 2,012 women who delivered at the hospital. Data obtained from the charts were parity, maternal age, body mass index (BMI), prepregnancy weight, weight gained during pregnancy, gestational age, hematocrit level, referral status, place of residence, fetal presentation, completion of antenatal care visits and maternal HIV infection. Sixty-five point two percent of subjects were aged 20-34 years old. Fifty-seven percent of subjects had a normal BMI and 13.2% were anemic. Thirty- seven point five percent, 32.9% and 29.6% gained too little, the correct amount and too much weight during pregnancy, respectively. Primiparity, too little weight gain and gestational age less than 37 weeks at delivery were all significantly associated with LBWN. Preterm babies were 25 times more likely to have a low birth weight than term infants (adjusted OR = 24.995; 95% CI: 16.824-37.133, p < 0.001). When maternal weight gain of any BMI group was inadequate, the subject had a 3.4 times greater risk (adjusted OR = 3.357; 95% CI: 22.114-5.332, p < 0.001) of having a LBWN. Primiparous women had a 1.7 times (adjusted OR=1.720; 95% CI: 1.182-2.503, p-0.005) greater risk of having a LBWN. The results from this study may be useful to plan maternal health programs for eastern Thailand. PMID:26867367

  20. Multivariate indices as estimates of dry body weight for comparative study of body size in Lepidoptera

    Enrique García-Barros

    2015-04-01

    Full Text Available Comparative studies on the size of adult Lepidoptera (moths and butterflies frequently rely on single linear estimates of body size, namely of forewing length or wingspan. As the shape of the wings of these insects – in fact, of all body parts – differs from one taxon to another, such estimates of body mass may not be adequate for comparisons across a wide taxonomic range. Using the length and width of the forewing, thorax and abdomen, as well as the wing area of 375 species and their correlations with dry body weight, several composite indices were determined that might be used in different circumstances. As the coefficients of determination from the multivariate regression models were rather high (R2>0.96, the results are believed to be reliable. A critical re-evaluation of the results indicates that important variations in the regression slopes described here would be expected, if at all, only from species with unusual body shapes. Incidentally, the bivariate relationships are in agreement with former comparative work on Lepidoptera and other terrestrial insects in that the relationship between body weight and single linear measurements follows a slightly negatively allometric trend, implying comparatively lighter bodies at the largest body sizes and relatively heavier ones at the shortest body sizes.

  1. An alternative to body mass index for standardizing body weight for stature.

    Bagust, A; Walley, T

    2000-09-01

    Although body mass index (BMI) has been adopted by WHO as an international measure of obesity, it lacks a theoretical basis, and empirical evidence suggests it is not valid for all populations. We determined standard weight-for-height using a model calibrated by multivariate analysis of observational data on body dimensions and health status in the USA (NHANES III). A multiple linear regression model based on a simple mathematical formulation accurately described the observed weight variations in this normal adult population. A standardized reference model using just two measurements (upper arm length and sitting height), readily applied in both clinical and research settings using lookup tables, improved explanatory power substantially compared to the best BMI formulation (r(2) increased 16.3% for males, 21.1% for females). Physical dysfunction and self-reported poor health showed strong trends with excess body weight. These findings need confirmation from larger population samples. PMID:10984553

  2. Association between eating out of home and body weight.

    Bezerra, Ilana N; Curioni, Cintia; Sichieri, Rosely

    2012-02-01

    Eating outside of the home environment on a frequent basis has been associated with weight gain. Food choices when eating out are usually high in energy content, which contributes to excessive energy intake; however, the available data on out-of-home eating and obesity are far from conclusive. This systematic review assesses the association between out-of-home eating and body weight in adults over 18 years of age. The literature databases searched included Medline, Embase, Lilacs, The Cochrane Library, and the ISI Web of Knowledge. The review includes a comprehensive quality assessment of all included observational studies, 20 cross-sectional studies, and 8 prospective cohort studies. All but one of the prospective cohort studies and about half of the cross-sectional analyses found a positive association between out-of-home eating and body weight. However, many methodological differences among the studies were found, such as the definition of out-of-home eating and its assessment, which limits comparisons. The results of the present analysis suggest that in future studies fast-food restaurants and other out-of-home dining venues should be analyzed separately, assessments based on a single 24-h recall should be avoided, and controls for at-home choices (which were not included in any of the studies reviewed) are necessary to evaluate this association.

  3. Phytochemicals in the Control of Human Appetite and Body Weight

    Sonia A. Tucci

    2010-03-01

    Full Text Available Since obesity has grown to epidemic proportions, its effective management is a very important clinical issue. Despite the great amount of scientific effort that has been put into understanding the mechanisms that lead to overconsumption and overweight, at the moment very few approaches to weight management are effective in the long term. On the other hand, modern society is also affected by the growing incidence of eating disorders on the other side of the spectrum such as anorexia and bulimia nervosa which are equally difficult to treat. This review will try to summarise the main findings available in the literature regarding the effect of plants or plant extracts (phytochemicals on human appetite and body weight. The majority of plant extracts are not single compounds but rather a mixture of different molecules, therefore their mechanism of action usually targets several systems. In addition, since some cellular receptors tend to be widely distributed, sometimes a single molecule can have a widespread effect. This review will attempt to describe the main phytochemicals that have been suggested to affect the homeostatic mechanisms that influence intake and body weight. Clinical data will be summarised and scientific evidence will be reviewed.

    2010-02-01

    Full Text Available Abstract Background This study aimed to canvass the nature of adolescent-parent interactions about weight, particularly overweight, and to explore ideas of how to foster supportive discussions regarding weight, both in the home and with family doctors. Methods A market research company was contracted to recruit and conduct a series of separate focus groups with adolescents and unrelated parents of adolescents from low-middle socio-economic areas in Sydney and a regional centre, Australia. Group discussions were audio recorded, transcribed, and then a qualitative content analysis of the data was performed. Results Nine focus groups were conducted; two were held with girls (n = 13, three with boys (n = 18, and four with parents (20 mothers, 12 fathers. Adolescent and parent descriptions of weight-related interactions could be classified into three distinct approaches: indirect/cautious (i.e. focus on eating or physical activity behaviors without discussing weight specifically; direct/open (i.e. body weight was discussed; and never/rarely discussing the subject. Indirect approaches were described most frequently by both adolescents and parents and were generally preferred over direct approaches. Parents and adolescents were circumspect but generally supportive of the potential role for family doctors to monitor and discuss adolescent weight status. Conclusions These findings have implications for developing acceptable messages for adolescent and family overweight prevention and treatment interventions.

    2013-03-01

    Full Text Available Obesity has become a major public health burden, not only by the rising prevalence but also because of the associated complications. Furthermore there is a number of diseases whose risk and onset is increased in subjects with overweight such as type 2 diabetes, dislipemias, tumors (endometrial, colon, breast, cancer, etc, skeletal disorders, digestive disturbances, cardiovascular diseases, respiratory disorders, psychological problems, obstetric and gynecological disorders.The prescription of psychotropic drugs is important and, in most countries, consumption has been increased in recent years. Indeed, several drugs used in the treatment of anxiety, depression, bipolar disorder, schizophrenia or epilepsy, can increase body weight and fat deposition or eventually decrease it. These side effects could make a previous situation of obesity to worsen, and it can even cause excessive weight gain in patients with a normal weight at the beginning of the treatment. This increase in adiposity may also contribute to the lack of adherence to the medication and thus a possible relapse of the patients.In this review we report the links between psychotropic drugs administration and weight gain as well as the potential mechanisms that are involved.DOI: http://dx.doi.org/10.14306/renhyd.17.1.4

    2011-01-01

    Here we review the emerging neurobiological understanding of the role of the brain’s reward system in the regulation of body weight in health and in disease. Common obesity is characterized by the over-consumption of palatable/rewarding foods, reflecting an imbalance in the relative importance of hedonic versus homeostatic signals. The popular ‘incentive salience theory’ of food reward recognises not only a hedonic/pleasure component (‘liking’) but also an incentive motivation component (‘wan...

  8. Variance components for body weight in Japanese quails (Coturnix japonica

    2005-03-01

    Full Text Available The objective of this study was to estimate the variance components for body weight in Japanese quails by Bayesian procedures. The body weight at hatch (BWH and at 7 (BW07, 14 (BW14, 21 (BW21 and 28 days of age (BW28 of 3,520 quails was recorded from August 2001 to June 2002. A multiple-trait animal model with additive genetic, maternal environment and residual effects was implemented by Gibbs sampling methodology. A single Gibbs sampling with 80,000 rounds was generated by the program MTGSAM (Multiple Trait Gibbs Sampling in Animal Model. Normal and inverted Wishart distributions were used as prior distributions for the random effects and the variance components, respectively. Variance components were estimated based on the 500 samples that were left after elimination of 30,000 rounds in the burn-in period and 100 rounds of each thinning interval. The posterior means of additive genetic variance components were 0.15; 4.18; 14.62; 27.18 and 32.68; the posterior means of maternal environment variance components were 0.23; 1.29; 2.76; 4.12 and 5.16; and the posterior means of residual variance components were 0.084; 6.43; 22.66; 31.21 and 30.85, at hatch, 7, 14, 21 and 28 days old, respectively. The posterior means of heritability were 0.33; 0.35; 0.36; 0.43 and 0.47 at hatch, 7, 14, 21 and 28 days old, respectively. These results indicate that heritability increased with age. On the other hand, after hatch there was a marked reduction in the maternal environment variance proportion of the phenotypic variance, whose estimates were 0.50; 0.11; 0.07; 0.07 and 0.08 for BWH, BW07, BW14, BW21 and BW28, respectively. The genetic correlation between weights at different ages was high, except for those estimates between BWH and weight at other ages. Changes in body weight of quails can be efficiently achieved by selection.

  10. Shaking weight loss away - Can vibration exercise reduce body fat?

    DARRYL COCHRANE

    2011-03-01

    Full Text Available An exercise modality that requires little time and physical exertion whilst providing the benefits of increased force, power, balance, flexibility, and weight loss would appeal to most people that may be at risk from an imbalanced lifestyle. One such exercise modality that has received a lot of attention has been vibration exercise (VbX, which evokes muscular work and elevates metabolic rate could be a potential method for weight reduction. Popular press has purported that VbX is quick, convenient, and 10 minutes of VbX is equivalent to one hour of traditional exercise, where it has been marketed as the new weight-loss and body toning workout. However, research studies have shown that muscle activation is elicited but the energy demand in response to VbX is quite low. Exhaustive VbX has been reported to produce a metabolic demand of 23 ml/kg/min compared to 44 ml/kg/min from an exhaustive cycle test. Different vibration frequencies have been tested with varying amplitudes and loads, but only small increases in metabolic rate have been reported. Based on these findings it has been indirectly calculated that a VbX session of 26Hz for 3 continuous minutes would only incur a loss of ~ 10.7g fat/hr. Following a 24-week programme of VbX, no observed differences were found in body composition and following 12 months of VbX the time to reach peak O2 was significantly higher in conventional exercise compared to VbX. However, one study has reported that percentage body fat decreased by 3.2% after eight months after VbX in comparison to resistance and control groups that performed no aerobic conditioning. The evidence to date, suggests that VbX can increase whole and local oxygen uptake; however, with additional load, high vibration frequency and/or amplitude it cannot match the demands of conventional aerobic exercise. Therefore, caution is required when VbX programmes are solely used for the purpose of reducing body fat without considering dietary and

  12. Medial orbital gyrus modulation during spatial perspective changes: Pre- vs. post-8 weeks mindfulness meditation.

    Tomasino, Barbara; Campanella, Fabio; Fabbro, Franco

    2016-02-01

    Mindfulness meditation exercises the ability to shift to an "observer perspective". That means learning to observe internally and externally arising stimulations in a detached perspective. Both before and after attending a 8-weeks mindfulness training (MT) participants underwent an fMRI experiment (serving as their own internal control) and solved a own-body mental transformation task, which is used to investigate embodiment and perspective taking (and an non-bodily mental transformation task as control). We found a stimulus×time-points interaction: the own-body mental transformation task (vs. non-bodily) in the post (vs. pre-MT) significantly increased activations in the medial orbital gyrus. The signal change in the right medial orbital gyrus significantly correlated with changes in a self-maturity personality scale. A brief MT caused increased activation in areas involved in self related processing and person perspective changes, together with an increase in self-maturity, consistently with the aim of mindfulness meditation that is exercising change in self perspective.

    2011-08-28

    Deficits in dopamine D2/D3 receptor (D2R/D3R) binding availability using PET imaging have been reported in obese humans and rodents. Similar deficits have been reported in cocaine-addicts and cocaine-exposed primates. We found that D2R/D3R binding availability negatively correlated with measures of body weight at the time of scan (ventral striatum), at 1 (ventral striatum) and 2 months (dorsal and ventral striatum) post scan in rats. Cocaine preference was negatively correlated with D2R/D3R binding availability 2 months (ventral striatum) post scan. Our findings suggest that inherent deficits in striatal D2R/D3R signaling are related to obesity and drug addiction susceptibility and that ventral and dorsal striatum serve dissociable roles in maintaining weight gain and cocaine preference. Measuring D2R/D3R binding availability provides a way for assessing susceptibility to weight gain and cocaine abuse in rodents and given the translational nature of PET imaging, potentially primates and humans.

    2014-10-01

    The aim of this study was to determine the effect of 8-week plyometric training (PT) on the leg power and jump and sprint performance in female soccer players. Eighteen female soccer players from Women Second League (age = 18.2 ± 2.3 years, height = 161.3 ± 5.4 cm, body mass = 56.6 ± 7.2 kg) were randomly assigned to control (n = 9) and plyometric (n = 9) groups. Both groups continued together with regular technical and tactical soccer training for 4 days a week. Additionally, the plyometric group underwent PT for 8 weeks, 1 day per week, 60-minute session duration. During the 8-week period, the control group was hindered from any additional conditioning training. All players' jumps (triple hop, countermovement jump, and standing broad jump), running speed (20 m), and peak power were evaluated before and after 8 weeks. No significant difference was found between the groups at pretest variables (p > 0.05). Significant improvements were found in the posttest of both the groups (p ≤ 0.05), except for 20-m sprint test in the control group (p > 0.05). Triple hop distance, countermovement jump, standing broad jump, peak power, and 20-m sprint test values were all significantly improved in the plyometric group, compared with the control group (p ≤ 0.05). We concluded that short duration PT is an improved important component of athletic performance in female soccer players. The results indicate that safe, effective, and alternative PT can be useful to strength and conditioning coaches, especially during competition season where less time is available for training.

  3. Nutrigenomics of Body Weight Regulation: A Rationale for Careful Dissection of Individual Contributors

    Jaap Keijer

    2014-10-01

    Full Text Available Body weight stability may imply active regulation towards a certain physiological condition, a body weight setpoint. This interpretation is ill at odds with the world-wide increase in overweight and obesity. Until now, a body weight setpoint has remained elusive and the setpoint theory did not provide practical clues for body weight reduction interventions. For this an alternative theoretical model is necessary, which is available as the settling point model. The settling point model postulates that there is little active regulation towards a predefined body weight, but that body weight settles based on the resultant of a number of contributors, represented by the individual’s genetic predisposition, in interaction with environmental and socioeconomic factors, such as diet and lifestyle. This review refines the settling point model and argues that by taking body weight regulation from a settling point perspective, the road will be opened to careful dissection of the various contributors to establishment of body weight and its regulation. This is both necessary and useful. Nutrigenomic technologies may help to delineate contributors to body weight settling. Understanding how and to which extent the different contributors influence body weight will allow the design of weight loss and weight maintenance interventions, which hopefully are more successful than those that are currently available.

This study examined the effects of 8 weeks of aerobic exercise on MMPR9R and TIMP-1 levels in type II diabetic women. Materials and Methods: This is a quasi-experimental study which included 20 in type II diabetic women with mean age of 53.2±2.5 years, body mass index (BMI of 28.73±2.27 and fat percentage of 30.6±2.05, who were randomly divided into two groups: aerobic exercise group (8 weeks, 3 sessions per week for 50 minutes and control group. To examine changes in MMPR9R and TIMP-1, 5 ml of blood was taken from the brachial vein of patients before and 48 hours after completion of exercise period and after 12 hours of fasting at rest. Data analysis was performed using SPSS-16 software with the independent and paired t-tests. Results: A significant decrease was observed in body mass index and body fat percentage in the experimental group (p<0.05. Compared with the control group, the aerobic exercise group showed a significant decrease in MMPR9R (p=0.01 and a significant increase in TIMP-1 levels (p=0.02 after 8 weeks of aerobic exercise. Conclusion: The results showed that aerobic exercise as a stimulus can change the levels of matrix metalloproteinases and their tissue inhibitors in order to prevent cardiovascular diseases in diabetics.

    Full Text Available Growth patterns of four lines of mice selected for body conformation were analyzed with the logistic function, in order to provide baseline information about the relationship between asymptotic weight and maturing rate of body weight. Two lines were divergently selected favoring the phenotypic correlation between body weight and tail length (agonistic selection: CBi+, high body weight and long tail; CBi-, low body weight and short tail, whereas the other two lines were generated by a disruptive selection performed against the correlation between the aforementioned traits (antagonistic selection: CBi/C, high body weight and short tail; CBi/L, low body weight and long tail. The logistic parameters A (asymptotic weight and k (maturing rate behaved in CBi/C and CBi- mice and in CBi+ females as expected in terms of the negative genetic relationship between mature size and earliness of maturing. An altered growth pattern was found in CBi/L mice and in CBi+ males, because in the former genotype, selected for low body weight, the time taken to mature increased, whereas in the latter, selected for high body weight, there was a non-significant increase in the same trait. In accordance with the selective criterion, different sources of genetic variation for body weight could be exploited: one inversely associated with earliness of maturing (agonistic selection, and the other independent of maturing rate (antagonistic selection, showing that genetic variation of A is partly independent of k.

    Full Text Available Abstract Background Current understanding of the associations between actual body weight status, weight perception, body dissatisfaction, and weight control practices among low-income urban African American adolescents is limited. The knowledge can help direct future intervention efforts. Methods Cross-sectional data including measured weight and height and self-reported weight status collected from 448 adolescents in four Chicago Public Schools were used. Results The prevalence of overweight and obesity (BMI ≥ 85th percentile was 39.8%, but only 27.2% considered themselves as obese, although 43.4% reported trying to lose weight. Girls were more likely to express weight dissatisfaction than boys, especially those with BMI ≥ 95th percentile (62.9% vs. 25.9%. BMI ≥ 85th percentile girls were more likely to try to lose weight than boys (84.6% vs. 66.7%. Among all adolescents, 27.2% underestimated and 67.2% correctly judged their own weight status. Multinomial logistic models show that those with BMI ≥ 85th percentile, self-perceived as obese, or expressed body dissatisfaction were more likely to try to lose weight; adjusted odds ratios and 95% confidence intervals were 4.52 (2.53–8.08, 18.04 (7.19–45.30, 4.12 (1.64–10.37, respectively. No significant differences were found in diet and physical activity between those trying to lose weight and those not trying, but boys who reported trying to lose weight still spent more television time (P Conclusion Gender differences in weight perception, body dissatisfaction, and weight control practices exist among African American adolescents. One-third did not appropriately classify their weight status. Weight perception and body dissatisfaction are correlates of weight control practices. Adolescents attempting to lose weight need be empowered to make adequate desirable behavioral changes.

    2008-12-01

    Full Text Available Abstract Background Excessive gestational weight gain promotes poor maternal and child health outcomes. Weight misperception is associated with weight gain in non-pregnant women, but no data exist during pregnancy. The purpose of this study was to examine the association of misperceived pre-pregnancy body weight status with excessive gestational weight gain. Methods At study enrollment, participants in Project Viva reported weight, height, and perceived body weight status by questionnaire. Our study sample comprised 1537 women who had either normal or overweight/obese pre-pregnancy BMI. We created 2 categories of pre-pregnancy body weight status misperception: normal weight women who identified themselves as overweight ('overassessors' and overweight/obese women who identified themselves as average or underweight ('underassessors'. Women who correctly perceived their body weight status were classified as either normal weight or overweight/obese accurate assessors. We performed multivariable logistic regression to determine the odds of excessive gestational weight gain according to 1990 Institute of Medicine guidelines. Results Of the 1029 women with normal pre-pregnancy BMI, 898 (87% accurately perceived and 131 (13% overassessed their weight status. 508 women were overweight/obese, of whom 438 (86% accurately perceived and 70 (14% underassessed their pre-pregnancy weight status. By the end of pregnancy, 823 women (54% gained excessively. Compared with normal weight accurate assessors, the adjusted odds of excessive gestational weight gain was 2.0 (95% confidence interval [CI]: 1.3, 3.0 in normal weight overassessors, 2.9 (95% CI: 2.2, 3.9 in overweight/obese accurate assessors, and 7.6 (95% CI: 3.4, 17.0 in overweight/obese underassessors. Conclusion Misperceived pre-pregnancy body weight status was associated with excessive gestational weight gain among both normal weight and overweight/obese women, with the greatest likelihood of excessive

    Diffusion-weighted magnetic resonance imaging (DWI) provides functional information and can be used for the detection and characterization of pathologic processes, including malignant tumors. The recently introduced concept of ''diffusion-weighted whole-body imaging with background body signal suppression'' (DWIBS) now allows acquisition of volumetric diffusion-weighted images of the entire body. This new concept has unique features different from conventional DWI and may play an important role in whole-body oncological imaging. This review describes and illustrates the basics of DWI, the features of DWIBS, and its potential applications in oncology. (orig.)

    2016-01-01

    Background: Body contouring performed for cosmetic purposes, or after weight loss, has the potential to improve body image and health-related quality of life (HRQL). The BODY-Q is a new patient-reported outcome (PRO) instrument designed to measure patient perceptions of weight loss and/or body contouring. In this article, we describe the psychometric properties of the BODY-Q scales after an international field-test. Methods: Weight loss and body contouring patients from Canada, United States, and United Kingdom were recruited between November 2013 and February 2015. Data were collected using an iPad directly into a web-based application or a questionnaire booklet. Rasch measurement theory analysis was used for item reduction and to examine reliability, validity, and ability to detect change. Results: The sample included 403 weight loss and 331 body contouring patients. Most BODY-Q items had ordered thresholds (134/138) and good item fit. Scale reliability was acceptable, ie, Person separation index >0.70 for 16 scales, Cronbach α ≥0.90 for 18 of 18 scales, and Test–retest ≥0.87 for 17 of 18 scales. Appearance and HRQL scores were lower in participants with more obesity-related symptoms, higher body mass index, and more excess skin and in those pre- versus postoperative body contouring. The 134 weight loss patients who completed the BODY-Q twice, either 6 weeks (weight loss/nonsurgical body contouring program) or 6 months (bariatric program) later, improved significantly on 7 appearance and 4 HRQL scales. Conclusion: The BODY-Q is a clinically meaningful and scientifically sound patient-reported outcome instrument that can be used to measure outcomes in patients who undergo weight loss and/or body contouring.

    2011-08-01

    Full Text Available Introduction:The present study evaluated the hypoglycemic perspectives and weight loss significance of dietary fiber. Dietary fiber was supplemented in commercial wheat flour (atta for the preparation of chapaties, a staple diet of South Asia. Male Sprague Dawley rats (n = 100 were randomly divided into 4 diet groups (n = 25 per group. The control group was fed basal diet that included commercial wheat flour chapati, cornstarch, corn oil, salt and vitamin mixture in such a way that 10% of the protein was available from the final diet. To the basal diet of other 3 groups, chapaties supplemented with 2% guar gum (GG 2%, 3% guar gum (GG 3% and 5% chickpea + 1% guar gum (CP5%+GG1% were added, respectively. All diets were fed to the rats for a period of 8 weeks to perceive the impact of respective compositions. Rats fed on CP 5% + GG1%, showed maximum glucose reduction (14.57% followed by GG 3% (11.64% and GG 2% (9.60% as compared to control diet. Likewise, rats fed on 3% GG showed maximum decline (7.90% in body weight. It was concluded that chapaties prepared from selected treatments provide an additional dietary fiber that could be supportive for diabetic and obese individuals.Results:The results indicated that addition of dietary fiber influenced the physical characteristics of chapati non-significantly. Maximum glucose concentration was found to be 112.50 mg/dL in control group followed by 101.70 and 99.41 mg/dL in groups fed on guar gum 2% and guar gum 3%, respectively. Lowest glucose concentration (96.11 mg/dL was observed in rats fed on the combination of chickpea 5 %+ guar gum 1%. Maximum serum protein concentration was found to be 6.39 g/dL in rats fed on combination of chickpea 5 % + guar gum 1% whilst the remaining three groups showed non significant variations with respect to each other.

    2015-06-01

    Full Text Available Purpose. The purpose of this study was to determine body image and body satisfaction in Polish adult men involved in resistance training and to investigate their relationships with objective anthropometric and training characteristics. Methods. The study included 176 males aged 18-31 years with 1-14 years resistance training experience. The Figure Rating Scale, Body Satisfaction Scale and a self-designed questionnaire were administered. Results. Approximately 62% of the participants would like to be more muscular, only 29% accepted their appearance and 9% would like to be less muscular. The body selected as the personal ideal (M = 5.34 was less muscular than the body considered by the participants to be ideal by other men (normative body; M = 6.07 and was more muscular than the body thought to be most attractive to women (M = 5.10. Actual and ideal body muscularity correlated positively with age and body mass, height and BMI. Dissatisfaction with trunk and motor characteristics correlated positively with ideal body and the body considered most attractive to women as well as with the discrepancy indices between the above factors and the actual body. Conclusions. Men regularly involved in resistance training were found to strive for a muscular physique. The normative body, the physique believed to be desired by other men, was more muscular than what was considered preferential to women. However, the latter constitutes a stronger determinant of the level of body satisfaction in men engaged in resistance training.

    2006-03-01

    Full Text Available Abstract Background Of concern to health educators is the suggestion that college females practice diet and health behaviors that contradict the 2005 dietary guidelines for Americans. In this regard, there remain gaps in the research related to dieting among college females. Namely, do normal weight individuals diet differently from those who are overweight or obese, and are there dieting practices used by females that can be adapted to promote a healthy body weight? Since it is well recognized that females diet, this study seeks to determine the dieting practices used among normal, overweight, and obese college females (do they diet differently and identify dieting practices that could be pursued to help these females more appropriately achieve and maintain a healthy body weight. Methods A total of 185 female college students aged 18 to 24 years participated in this study. Height, weight, waist and hip circumferences, and skinfold thickness were measured to assess body composition. Surveys included a dieting practices questionnaire and a 30-day physical activity recall. Participants were classified according to body mass index (BMI as normal weight (n = 113, overweight (n = 35, or obese (n = 21. Data were analyzed using JMP IN® software. Descriptive statistics included means, standard deviations, and frequency. Subsequent data analysis involved Pearson X2 and one-way analysis of variance with comparison for all pairs that were significantly different using Tukey-Kramer honestly significant difference test. Results Outcomes of this study indicate the majority of participants (83% used dieting for weight loss and believed they would be 2% to 6% greater than current weight if they did not diet; normal weight, overweight, and obese groups perceived attractive weight to be 94%, 85%, and 74%, respectively, of current weight; 80% of participants reported using physical activity to control weight, although only 19% exercised at a level that would

    Pulses are low in energy density, supporting their inclusion in the diet for the management of risk factors of the metabolic syndrome (MetSyn). The aim of the present study was to describe the effects of frequent consumption (five cups/week over 8 weeks) of pulses (yellow peas, chickpeas, navy beans and lentils), compared with counselling to reduce energy intake by 2093 kJ/d (500 kcal/d), on risk factors of the MetSyn in two groups (nineteen and twenty-one subjects, respectively) of overweight or obese (mean BMI 32·8 kg/m2) adults. Body weight, waist circumference, blood pressure, fasting blood parameters and 24 h food intakes were measured at weeks 1, 4 and 8. Blood glucose, insulin, C-peptide, glucagon-like peptide-1 (GLP-1) and ghrelin were measured after a 75 g oral glucose load at weeks 1 and 8. At week 8, both groups reported reductions in energy intake, waist circumference, systolic blood pressure, glycosylated Hb (HbA1c) and glucose AUC and homeostasis model of insulin resistance (HOMA-IR) following the glucose load (P < 0·05). However, HDL, fasting C-peptide and insulin AUC responses were dependent on diet (P < 0·05). HDL and C-peptide increased by 4·5 and 12·3 %, respectively, in the pulse group, but decreased by 0·8 and 7·6 %, respectively, in the energy-restricted group. Insulin AUC decreased in both females and males on the energy-restricted diet by 24·2 and 4·8 %, respectively, but on the pulse diet it decreased by 13·9 % in females and increased by 27·3 % in males (P < 0·05). In conclusion, frequent consumption of pulses in an ad libitum diet reduced risk factors of the MetSyn and these effects were equivalent, and in some instances stronger, than counselling for dietary energy reduction.

    Children and adolescents tend to lose weight, which may be associated with misperceptions of weight. Previous studies have emphasized establishing correlations between eating disorders and an overestimated perception of body weight, but few studies have focused on an underestimated perception of body weight. The objective of this study was to explore the relationship between misperceptions of body weight and weight-related risk factors, such as eating disorders, inactivity, and unhealthy behaviors, among overweight children who underestimated their body weight. We conducted a cross-sectional, descriptive study between December 1, 2006 and February 15, 2007. A total of 29,313 children and adolescents studying in grades 4-12 were enrolled in this nationwide, cross-sectional survey, and they were asked to complete questionnaires. A multivariate logistic regression using maximum likelihood estimates was used. The prevalence of body weight misperception was 43.2% (26.4% overestimation and 16.8% underestimation). Factors associated with the underestimated perception of weight among overweight children were parental obesity, dietary control for weight loss, breakfast consumption, self-induced vomiting as a weight control strategy, fried food consumption, engaging in vigorous physical activities, and sleeping for >8 hours per day (odds ratios=0.86, 0.42, 0.88, 1.37, 1.13, 1.11, and 1.17, respectively). In conclusion, the early establishment of an accurate perception of body weight may mitigate unhealthy behaviors. PMID:26965769

  6. Differential effects of cigarette smoking on birth weight by maternal body mass index.

    Heinz-Partington, Sean; Condous, George; Mongelli, Max

    2016-07-01

    Links between low birth weight and tobacco exposure in utero are well established, as are associations between maternal body mass index (BMI) and birth weight. This study further develops those relationships. In particular, this article analyses whether high maternal weight acts to dampen the previously established link between tobacco exposure and low birth weight. A retrospective cohort study was undertaken, reviewing the birth weights of 13,473 live singleton pregnancies born at a Sydney regional hospital between 1998 and 2003. Results demonstrated a statistically significant decline in reduced birth weight as BMI increased. That is, as body weight increases, tobacco use has a smaller effect on reducing birth weight. Inversely, the effect on reducing birth weight for each cigarette smoked by leaner women was greater. In effect, the adverse influence of tobacco use on birth weight appears to be modulated by increasing maternal BMI. PMID:27013353

    2014-04-01

    This study investigated associations between eating regulation behaviors and body mass index (BMI), weight, and percent body fat in male and female students over the first two years of college. Subjects included 328 college students (215 females and 113 males). Height and weight (via standard techniques), body composition (via bioelectrical impedance analysis), and eating regulation behaviors (using the Regulation of Eating Behavior Scale) were conducted two to three times during both the freshman and sophomore years. Significant associations between eating regulation and BMI, weight, and/or percent body fat were shown mostly in females. In females, higher BMI, weight, and/or percent body fat at the end of the second year of college were found in those with low levels of autonomous, intrinsic motivation, and identified regulation, and high levels of amotivation, while lower BMI, weight, and/or percent body fat were associated with high levels of autonomous, intrinsic motivation, and identified regulation, and low levels of amotivation. The findings that specific eating behaviors in females during the first two years of college influence BMI, weight, and/or percent body fat may be useful for inclusion in university programs focused on college student health to help decrease the risk of obesity and disordered eating/eating disorders in female college students.

    2012-03-01

    To quantify the response to selection, heritability and genetic correlations between weight and size of Litopenaeus vannamei, the body weight (BW), total length (TL), body length (BL), first abdominal segment depth (FASD), third abdominal segment depth (TASD), first abdominal segment width (FASW), and partial carapace length (PCL) of 5-month-old parents and of offspnng were measured by calculating seven body measunngs of offspnng produced by a nested mating design. Seventeen half-sib families and 42 full-sib families of L. vannamei were produced using artificial fertilization from 2-4 dams by each sire, and measured at around five months post-metamorphosis. The results show that hentabilities among vanous traits were high: 0.515±0.030 for body weight and 0.394±0.030 for total length. After one generation of selection. the selection response was 10.70% for offspring growth. In the 5th month, the realized heritability for weight was 0.296 for the offspnng generation. Genetic correlations between body weight and body size were highly variable. The results indicate that external morphological parameters can be applied dunng breeder selection for enhancing the growth without sacrificing animals for determining the body size and breed ability; and selective breeding can be improved significantly, simultaneously with increased production.

    The β-2 and β-3 adrenergic receptors (ADRB2 and ADRB3) are thought to play a role in energy expenditure and lipolysis. However, the effects of the ADRB2 glutamine (Gln) 27 glutamic acid (glutamate) (Glu) and ADRB3 tryptophan (Trp) 64 arginine (Arg) polymorphisms on weight loss remain controversial. The aim of this study was to investigate the effect of these polymorphisms on changes in weight and body composition during a controlled weight-loss program. One hundred seventy-three healthy overweight and obese participants (91 women, 82 men) aged 18-50 years participated in a 22-week-long intervention based on a hypocaloric diet and exercise. They were randomly assigned to 1 of 4 groups: strength, endurance, strength and endurance combined, and physical activity recommendations only. Body weight, body mass index (BMI), and body composition variables were assessed before and after the intervention. Genetic analysis was carried out according to standard protocols. No effect of the ADRB2 gene was shown on final weight, BMI, or body composition, although in the supervised male group, Glu27 carriers tended to have greater weight (p = 0.019, 2.5 kg) and BMI (p = 0.019, 0.88 kg/m(2)) reductions than did noncarriers. There seems to be an individual effect of the ADRB3 polymorphism on fat mass (p = 0.004) and fat percentage (p = 0.036), in addition to an interaction with exercise for fat mass (p = 0.038). After the intervention, carriers of the Arg64 allele had a greater fat mass and fat percentage than did noncarriers (p = 0.004, 2.8 kg). In conclusion, the ADRB2 Gln27Glu and ADRB3 Trp64Arg polymorphisms may influence weight loss and body composition, although the current evidence is weak; however, further studies are necessary to clarify their roles.

  13. Physical Activity: An Important Adaptative Mechanism for Body-Weight Control

    Finelli, Carmine; Gioia, Saverio; La Sala, Nicolina

    2012-01-01

    We review the current concepts about energy expenditure and evaluate the physical activity (PhA) in the context of this knowledge and the available literature. Regular PhA is correlated with low body weight and low body fat mass. The negative fat balance is probably secondary to this negative energy balance. Nonexercise activity thermogenesis (NEAT) and physical activity, that is crucial for weight control, may be important in the physiology of weight change. An intriguing doubt that remains ...

  14. Effects of body weight on discriminative-stimulus control by phencyclidine in the pigeon.

    Massey, B W; McMillan, D. E.

    1987-01-01

    Using a color-tracking procedure with responses reinforced under a second-order schedule, the discriminative-stimulus properties of phencyclidine were studied in pigeons maintained at 70%, 80%, or 90% of their free-feeding weights. The generalization curves for phencyclidine were similar at all three body weights. Generalization curves for pentobarbital, d-amphetamine, and saline were also unrelated to body weight. These data suggest that food deprivation may not influence the discriminative-...

  15. Methodology and factors influencing the association of body weight, performance parameters with linear body measurements assessment in poultry

    2015-10-01

    Full Text Available The preceding review gives some insight on different methods and factors which influence the association of live weight, performance parameters with linear body measurements assessment in poultry. The relationship existing among linear body parameters provides useful information on the performance and carcass value of poultry.  Linear body measurements  variability in poultry arises due to genotypic and environmental effects, and the magnitude of variability may differs under different management practices and environmental conditions. The knowledge of the relationship existing between live weight,  carcass traits  and other performance traits in poultry is crucial because it enable us to predict the body weight and performance  from linear body parts and vice versa. This is on the background that different methods have been employed to assess the association of live weight, performance parameters with linear body measurements in poultry. It is suffice to suggest that the understating of the relationship between linear body measurements and performance traits in poultry could be useful in designing appropriate management, selection and breeding  programs for utilization of poultry genetic resources. Therefore, the conclusion that linear body measurements information for a particular poultry species or breed is important for breed or species identification and economic valuation in its utilization, might be valid.

  16. Maternal weight and body composition in the first trimester of pregnancy.

    Fattah, Chro

    2012-02-01

    OBJECTIVE: Previous studies on weight gain in pregnancy suggested that maternal weight on average increased by 0.5-2.0 kg in the first trimester of pregnancy. This study examined whether mean maternal weight or body composition changes in the first trimester of pregnancy. DESIGN: Prospective observational study. POPULATION: We studied 1,000 Caucasian women booking for antenatal care in the first trimester of pregnancy. SETTING: Large university teaching hospital. METHODS: Maternal height and weight were measured digitally in a standardized way and Body Mass Index (BMI) was calculated. Maternal body composition was measured using segmental multifrequency Bioelectrical Impedance Analysis (BIA). Sonographic examination confirmed the gestational age and a normal ongoing singleton pregnancy in all subjects. MAIN OUTCOME MEASURES: Maternal weight, maternal body composition. RESULTS: The mean BMI was 25.7 kg\\/m(2) and 19.0% of the women were in the obese category (> or =30.0 kg\\/m(2)). Cross-sectional analysis by gestational age showed that there was no change in mean maternal weight, BMI, total body water, fat mass, fat-free mass or bone mass before 14 weeks gestation. CONCLUSIONS: Contrary to previous reports, mean maternal weight and mean body composition values remain unchanged in the first trimester of pregnancy. This has implications for guidelines on maternal weight gain during pregnancy. We also recommend that calculation of BMI in pregnancy and gestational weight gain should be based on accurate early pregnancy measurements, and not on self-reported or prepregnancy measurements.

  3. Body-weight perceptions and selected weight-management goals and practices of high school students--United States, 1990.

    1991-11-01

    Among adults, overweight is associated with elevated serum cholesterol levels, elevated blood pressure, and noninsulin-dependent diabetes and is an independent risk factor for coronary heart disease. Youth who are overweight and remain overweight as adults may increase their risk for certain chronic diseases in adulthood. However, overemphasis on thinness during adolescence may contribute to potentially harmful weight-management practices and eating disorders such as anorexia nervosa and bulimia nervosa. This report presents self-reported body-weight perceptions and selected weight-management goals and practices among high school students in the United States. PMID:1921967

    Cornual pregnancy is a rare form of ectopic pregnancy that usually leads to uterine rupture with resultant life threatening hemorrhage. The mortality of interstitial pregnancies is more than twice that of other tubal pregnancies. Cornual pregnancies often rupture later than other tubal pregnancies because the myometrium is more distensible than the fallopian tube. We report a case where a patient presented at 8 weeks of gestational age with ruptured cornual ectopic pregnancy and hemoperitone...

    2004-03-01

    There have been some observations that low body weight and a low level of some hormones (e.g. IGF-1) during the first half of life are predictors of longer life in mice. However, contradictions in the available data on the biomarkers of aging and predictors of longevity have shown that the research in these fields has become a controversial pursuit. In our study we addressed the following questions: (i) Can particular physiological parameters (body weight, food intake, estrus function, body temperature, incidence of chromosome aberrations in bone marrow cells) measured at the age of 3 and 12 months be a predictor of longevity and the rate of tumor development in five strains of mice? (ii) Can a heavy body weight at the age of 3 and 12 months be a predictor of longevity and high tumor risk in five strains of mice? Mice of five strains-CBA, SHR, SAMR, SAMP and transgenic HER-2/neu (FVB/N)-were under observation from the age of 2-3 months until natural death. Body weight and temperature, food consumption, and estrous cycle were longitudinally studied in all animals. Tumors discovered at autopsy were studied morphologically. We calculated the life span's parameters (mean, maximum, mortality rate, mortality rate doubling time) as well as their correlation with other parameters studied. The longest living CBA mice have the lowest body weight at the ages of 3 and 12 months, the lowest food consumption, body temperature, incidence of chromosome aberrations and spontaneous tumor incidence. In comparison with all other mouse strains they also have the latest disturbances in estrus function and highest body weight gain. The shortest living transgenic HER-2/neu mice have the lowest weight at the ages of 12 months, the lowest body weight gain, maximal body temperature, the most rapid disturbances in estrus function and the highest incidence of chromosome aberrations and tumor incidence in comparison to all other mouse strains. Our findings have shown that heavier body weight at

  20. Relationships between neonatal weight, limb lengths, skinfold thicknesses, body breadths and circumferences in an Australian cohort.

    Emma Pomeroy

    Full Text Available BACKGROUND: Low birth weight has been consistently associated with adult chronic disease risk. The thrifty phenotype hypothesis assumes that reduced fetal growth impacts some organs more than others. However, it remains unclear how birth weight relates to different body components, such as circumferences, adiposity, body segment lengths and limb proportions. We hypothesized that these components vary in their relationship to birth weight. METHODS: We analysed the relationship between birth weight and detailed anthropometry in 1270 singleton live-born neonates (668 male from the Mater-University of Queensland Study of Pregnancy (Brisbane, Australia. We tested adjusted anthropometry for correlations with birth weight. We then performed stepwise multiple regression on birth weight of: body lengths, breadths and circumferences; relative limb to neck-rump proportions; or skinfold thicknesses. All analyses were adjusted for sex and gestational age, and used logged data. RESULTS: Circumferences, especially chest, were most strongly related to birth weight, while segment lengths (neck-rump, thigh, upper arm, and especially lower arm and lower leg were relatively weakly related to birth weight, and limb lengths relative to neck-rump length showed no relationship. Skinfolds accounted for 36% of birth weight variance, but adjusting for size (neck-rump, thigh and upper arm lengths, and head circumference, this decreased to 10%. There was no evidence that heavier babies had proportionally thicker skinfolds. CONCLUSIONS: Neonatal body measurements vary in their association with birth weight: head and chest circumferences showed the strongest associations while limb segment lengths did not relate strongly to birth weight. After adjusting for body size, subcutaneous fatness accounted for a smaller proportion of birth weight variance than previously reported. While heavier babies had absolutely thicker skinfolds, this was proportional to their size. Relative

  1. [Ideal body weight of a young woman--sociocultural and health aspects].

    Kärkkäinen, Ulla; Dadi, Yasmina; Keski-Rahkonen, Anna

    2015-01-01

    A common question made by a young person attending a practice concerns her/his ideal body weight. Culture and health may result in a conflicting definition of good weight. Discontent with one's own body can motivate for successful weight control, but may also lead to unnecessary dieting or disturbed eating. Too strict dieting and accentuating of weight control increase the risk of eating disorders, but on the other hand, adolescent overweight is a risk factor of obesity in adulthood as well.

  2. Connecting theory to fat talk: body dissatisfaction mediates the relationships between weight discrepancy, upward comparison, body surveillance, and fat talk.

    Arroyo, Analisa

    2014-06-01

    The fat talk literature is meager in terms of offering theoretical explanations for women's self-disparaging communication. The research presented here sought to establish a relationship between three prominent body image theories - self-discrepancy theory, social comparison theory, and objectification theory - and fat talk by proposing body dissatisfaction as a potential mediating mechanism. Young adult women (N=201) completed an online questionnaire. As predicted, results revealed that body dissatisfaction significantly mediated the relationships between weight discrepancy, upward comparison, body surveillance and fat talk. Effect size estimates indicated that the size of each indirect effect was medium in magnitude. PMID:24958666

    2009-01-01

    While lifestyle modifications are currently used as firstline treatment for subjects with gastroesophageal reflux disease (GERD), the pathogenetic role of lifestyle factors and consequently, the efficacy of lifestyle measures is controversial. Our aim was to systematically review the pathogenetic link between overweight/ obesity, dietary habits, physical activity and GERD, and the beneficial effect of specific recommended changes, by means of the available literature from the 1999 to the present. Obesity, in particular, abdominal obesity, plays a key role in determining GERD symptoms and complications through mechanical and metabolic effects. Controlled weight loss (by diet or surgery) is effective in improving GERD symptoms. No definitive data exist regarding the role of diet and, in particular, of specific foods or drinks, in influencing GERD clinical manifestations. Moderate physical activity seems to be beneficial for GERD, while vigorous activity may be dangerous in predisposed individuals. In conclusion, being obese/overweight and GERD-specific symptoms and endoscopic features are related, and weight loss significantly improves GERD clinical-endoscopic manifestations. The role of dietary behavior, mainly in terms of specific dietary components, remains controversial. Mild routine physical activity in association with diet modifications, i.e. a diet rich in fiber and low in fat, is advisable in preventing reflux symptoms.

  4. Value of early weight measurements as predictors of body weight at later ages in reindeer

    C.J. Petersson

    1993-12-01

    Full Text Available Phenotypic variances in live weight in a reindeer population and repeatabilities of the weights were estimated. The population consisted of 1847 and 1878 unselected male and female calves respectively, for which data from weighings at 2 and 7 months of age were available. All individuals in a selected population, consisting of 469 of the heaviest females, were weighed at 2, 7 and 19 months of age. The data were colleted during four successive years, 1986 - 1989. An indirect selection model for improving female weight at 19 months of age was proposed. Variance in the unselected population was higher between animals than within animals. Repeatability was estimated to be 0.636 for the male calves and 0.609 for the female calves. In the selected population, within-individual variance was higher than between-animal variance. Repeatabilities were, after correction for the effect of selection, 0.316 (between 2 and 19 months and 0.548 (between 7 and 19 months. The aim of the selection model was to increase the average weight in the primiparous group to improve their calf production ability. Using the model, the number of animals weighing equal to or more than a certain threshold weight and the number needed for recruitment at 19 months of age could be determined.

  5. Effect of endorsed body weight on specific absorption rate during magnetic resonance imaging

    As a routine safety of the patients undergoing magnetic resonance imaging (MRI), the limits of radiofrequency (RF) specific absorption rate (SAR) are set by the manufacturers of all MRI systems because RF causes thermo genesis of the RF exposed tissue. It has been mandatory practice to endorse body weight and age of the patients required by the MRI systems for the SAR check. The problems arise on those patients who are critically ill, and consequently body weight could not be measured. In such cases, approximate body weight has to be endorsed. In case of underweight and overweight patients, sometimes SAR check does not permit to run the MRI pulse sequences. Also, in such cases, body weight remains the parameter which is being changed to get the MRI done. The purpose of this study is to assess the change of SAR with endorsed body weight. The change of SAR was recorded with the endorsed weight using phantoms and most commonly used T1 and T2 weighted pulse sequence on clinical MRI system. At true endorsed weight, using respective coils and the head and spine coil phantoms, the body averaged and localised SAR were found to be within limits while this was not the case with body coil phantom. Unrealistic endorsed weights are permissible for the adult age cases in all coils while using the routine T1 and T2 weighted pulse sequences. This finding is absolutely new in the field and certainly, will be of great applicability to develop a uniform and standard system of SAR checks in the patient interest. (author)

  6. Body weight/image perceptions and prevalence of obesity among adolescents-Kerala, India

    K Ramesh

    2012-01-01

    Full Text Available Introduction: Obesity can be seen as the first wave of a defined cluster of non communicable diseases called "New World Syndrome" creating an enormous socioeconomic and public health burden in poorer countries. The rising prevalence of childhood/adolescent obesity cannot be addressed by a single etiology. Multiple factors plays role and among them perception on body weight and image plays vital role in adolescents. So the objective of this study was to know the perceptions of adolescents on their body weight and body image. Materials and Methods: A cross-sectional study was conducted among students of high schools of Thiruvananthapuram city corporation, Kerala, India. The sample size of this study was 1718 and the technique adopted is multistage and stratified random sampling. Data was collected using pre designed and pretested semi-structured questionnaire which is self-administered. Body mass index was calculated based on physical measurements such as height and weight using standard methods. Results: This study revealed that 67.3% of study subjects underestimated their body weight and 15.5% over estimated their body weight. The prevalence of overweight/obesity is high among those who underestimated their body weight (18.7% compared to subjects who overestimated (6.7% but the prevalence of underweight is high among the subjects who overestimated their body weight (60.8% compared to subjects who underestimated (22%. Conclusion: Schools are probably the ideal medium of intervention as they are central to children′s lives and information can be relatively quickly dissipated through this channel and Helping adolescents to attain a realistic, positive perception of their body weight and image through health education.

    2014-12-01

    The aims of this cross-sectional study were to examine the associations between body weight and mental health indicators including depression, social phobia, insomnia, and self-esteem among Taiwanese adolescents in Grades 7-12. The body mass index (BMI) of 5254 adolescents was calculated based on self-reported weight and height measurements. Body weight status was determined by the age- and gender-specific International Obesity Task Force reference tables. By using participants of average weight as the reference group, the association between body weight status (underweight, overweight, and obesity) and mental health indicators (depression, social phobia, insomnia, and self-esteem) were examined by using multiple regression analysis. The possible moderating effects of sociodemographic characteristics on the association were also examined. After controlling for the effects of sociodemographic characteristics, both overweight (p phobia, or insomnia were found between those who were overweight/obese and those of average weight. No significant differences in the four mental health indicators were found between those who were underweight and those of average weight. Sociodemographic characteristics had no moderating effect on the association between body weight and mental health indicators. In conclusion, mental health and school professionals must take the association between overweight/obesity and self-esteem into consideration when approaching the issue of mental health among adolescents.

    The current study was conducted to investigate the effect of short-term selection in Japanese quail for 4-wk BW and estimate genetic parameters of BW, carcass traits, and egg weight. A selected line and control line were randomly selected from a base population. In each generation, 39 sires and 7...... improve carcass traits. Also, intense selection resulting in high rates of inbreeding might result in decreased response to selection due to inbreeding depression....

  9. Pre-Pregnancy Body Mass Index, Gestational Weight Gain, and Birth Weight: A Cohort Study in China.

    Shaoping Yang

    Full Text Available To assess whether pre-pregnancy body mass index (BMI modify the relationship between gestational weight gain (GWG and child birth weight (specifically, presence or absence of low birth weight (LBW or presence of absence of macrosomia, and estimates of the relative risk of macrosomia and LBW based on pre-pregnancy BMI were controlled in Wuhan, China.From June 30, 2011 to June 30, 2013. All data was collected and available from the perinatal health care system. Logistic regression models were used to estimate the independent association among pregnancy weight gain, LBW, normal birth weight, and macrosomia within different pre-pregnancy BMI groups. We built different logistic models for the 2009 Institute of Medicine (IOM Guidelines and Chinese-recommended GWG which was made from this sample. The Chinese-recommended GWG was derived from the quartile values (25th-75th percentiles of weight gain at the time of delivery in the subjects which comprised our sample.For LBW children, using the recommended weight gain of the IOM and Chinese women as a reference, the OR for a pregnancy weight gain below recommendations resulted in a positive relationship for lean and normal weight women, but not for overweight and obese women. For macrosomia, considering the IOM's recommended weight gain as a reference, the OR magnitude for pregnancy weight gain above recommendations resulted in a positive correlation for all women. The OR for a pregnancy weight gain below recommendations resulted in a negative relationship for normal BMI and lean women, but not for overweight and obese women based on the IOM recommendations, significant based on the recommended pregnancy weight gain for Chinese women. Of normal weight children, 56.6% were above the GWG based on IOM recommendations, but 26.97% of normal weight children were above the GWG based on Chinese recommendations.A GWG above IOM recommendations might not be helpful for Chinese women. We need unified criteria to

  11. Age and body weight of Moroccan local cattle at puberty: Effect of season

    Moroccan local cattle are a distinct breed comprising almost 90% of the total cattle population of 2.5 million. The age and the body weight of some 1662 heifers attaining puberty were determined under two production systems by monitoring plasma progesterone levels as an indicator of the first ovulation. The effect of season on these parameters was also studied. Ovarian cyclicity commenced in 50% of heifers by the age of 16.5 months and at a body weight of 144 kg (70% of the mature body weight). The time of puberty was correlated with both age and body weight and was influenced by both the season of the year at which puberty was reached and the system of rearing. The mean age at which behavioural oestrus was first observed and the heifer inseminated was 26.5 months. Fifty per cent of 546 heifers were pregnant by 27 months of age. (author). 18 refs, 7 figs

  13. Bulimia nervosa symptomatology and body image disturbance associated with distance running and weight loss.

    Gleaves, D H; Williamson, D A; Fuller, R D

    1992-09-01

    To investigate the hypothesis that problems characteristic of eating disorders may often be associated with distance running, 20 women who had lost weight through distance running were compared with a control group who did not exercise and had not lost weight and a comparison group of bulimia nervosa patients. Dependent variables were measures of depression, bulimia nervosa symptomatology, and body image disturbance. No differences were found between the runner group and the normal controls. Bulimics differed from runners and controls on most measures. Thus, the results did not support the proposition that weight loss through running leads to problems related to eating and body image. The failure to find disturbances in body image in runners suggests that body image disturbances are not a direct result of weight loss, as suggested by some theorists. PMID:1422651

  14. Assessing stability of body weight in the brushtail possum (Trichosurus vulpecula).

    Cameron, Kristie E; Bizo, Lewis A; Starkey, Nicola J

    2015-01-01

    When conducting controlled laboratory studies with non-traditional laboratory animals it is important that methods for determining body weight stability are reliable. This helps ensure the health and welfare of animals when they are maintained during periods of free feeding or food restriction. This study compared different methods for determining body weight stability in six common brushtail possums (Trichosurus vulpecula) maintained on a free-feeding diet under laboratory conditions. A criterion of five consecutive weighings with less than ±2.5% change across days and no more than two consecutive days of weight loss or weight gain was judged to be the most suitable criteria for determining stability. It is important to study non-traditional animals, especially endangered or pest species, under controlled laboratory conditions and to have robust methods for establishing body weight stability.

    Dragone, Davide; Ziebarth, Nicolas R.

    2015-01-01

    This paper develops a conceptual framework that can explain why economic development goes along with increases in body weight and obesity rates. We first introduce the concept of novelty consumption, which refers to an increase in food availability due to trade or innovation. Then we study how novel food products alter the optimal consumption bundle and welfare, and possibly lead to changes in body weight. We test our model employing the German reunification as a fast motion natural experimen...

  19. Body Dissatisfaction and Weight-Related Teasing: A Model of Cognitive Vulnerability to Depression Among Women

    Benas, Jessica S.; Uhrlass, Dorothy J.; Gibb, Brandon E.

    2010-01-01

    Although a number of studies have linked body dissatisfaction to depressive symptoms, few have done so within the framework of a vulnerability-stress model. We hypothesized that women’s levels of body dissatisfaction would interact with recent experiences of vulnerability-congruent negative life events (i.e., weight-related teasing) to predict prospective changes in depressive symptoms. Consistent with these hypotheses, experiences of weight-related teasing were more strongly related to depre...

    2008-01-01

    BACKGROUND: Although both maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) may affect birth weight, their separate and joint associations with complications of pregnancy and delivery and with postpartum weight retention are unclear. OBJECTIVES: We aimed to investigate...... prepregnancy BMI with cesarean delivery and were strongly associated with high postpartum weight retention. Moreover, greater weight gains and high maternal BMI decreased the risk of growth restriction and increased the risk of the infant's being born large-for-gestational-age or with a low Apgar score...

  2. Evaluation of body weight of sea cucumber Apostichopus japonicus by computer vision

    Liu, Hui; Xu, Qiang; Liu, Shilin; Zhang, Libin; Yang, Hongsheng

    2015-01-01

    A postichopus japonicus (Holothuroidea, Echinodermata) is an ecological and economic species in East Asia. Conventional biometric monitoring method includes diving for samples and weighing above water, with highly variable in weight measurement due to variation in the quantity of water in the respiratory tree and intestinal content of this species. Recently, video survey method has been applied widely in biometric detection on underwater benthos. However, because of the high flexibility of A. japonicus body, video survey method of monitoring is less used in sea cucumber. In this study, we designed a model to evaluate the wet weight of A. japonicus, using machine vision technology combined with a support vector machine (SVM) that can be used in field surveys on the A. japonicus population. Continuous dorsal images of free-moving A. japonicus individuals in seawater were captured, which also allows for the development of images of the core body edge as well as thorn segmentation. Parameters that include body length, body breadth, perimeter and area, were extracted from the core body edge images and used in SVM regression, to predict the weight of A. japonicus and for comparison with a power model. Results indicate that the use of SVM for predicting the weight of 33 A. japonicus individuals is accurate ( R 2=0.99) and compatible with the power model ( R 2 =0.96). The image-based analysis and size-weight regression models in this study may be useful in body weight evaluation of A. japonicus in lab and field study.

  3. Increases in body weight and nutritional status of transplanted Alaskan caribou

    Patrick Valkenburg

    2000-04-01

    Full Text Available Body weight and natality rate in ungulates can be useful indices to nutririon, bur they may also be influenced by genetic and climatic factors. Because caribou {Rangifer tarandus granti are distributed as discrete populations of metapopulations (i.e., herds that are usually reproductively isolated from each other for unknown periods, it is difficult to separate the influence of genetics and nutrition on body weight, especially where historical data are lacking. To help elucidate the influence of nutrition on potential variation in body weight and natality of caribou in Alaska, we reviewed data for body weight and natality in 5 populations which resulted from Transplants to previously ungrazed ranges, or to areas where reindeer and caribou had been absent for many decades. In 2 of 5 populations body weight increased significantly, and likely increased in the other 3 populations, but data were insufficient. Natality rate increased in all 5 populations, proportion of fecund yearlings was high and 3 of the 5 newly established herds increased at about the maximum biological potential for the species (lambda=1.35. In the Adak transplant, a lactating yearling was documented. These 5 transplanted populations provide additional evidence that body weight and natality rate in Alaskan caribou are sensitive to changes in population density and relatively short-term (i.e., 10 years increases in grazing pressure independenr of climate and genetics.

    2005-01-01

    Full Text Available A breeding experiment was conducted to assess the relationships among body weights and linear body measurements in rabbit breeds and crosses. Data on 259 and 215 kits from 73 and 62 litters at 35 and 56 weaning and post- weaning ages respectively were used in the study. The litters representing 8 genotypes evolved from random mating involving 49 does and 13 bucks. The traits measured were body Weights (BWT , Nose to Shoulder Length ( NTS , Shoulder to Tail Length ( STL , Trunk Length ( TKL , heart girth ( HGT, height at withers ( HTW and length of ear. Measurements of the body components for each genotype were regressed against live weight at 35 and 56 days of age using linear and non-linear (exponential and polynomial regression analyses. The relationship between live weight and each of the measurement were also assessed. The regression equations, estimates of parameters and coefficients of determination ( R for the fitted functions were determined. Body measurements and weight were generally positive and significant (p < 0.001 demonstrating strong inter-relationship among the variables. The coefficient of determination varied from 5.27 to 90.3 and from 0.090 to 90.6 at 35 and 56 days respectively. Based on R , polynomial function was superior in terms of goodness of fit to the data and its ability to predict. Body weight was better predicted using STL of genotype NZWDBD x NZWDBD at both ages.

    Cachexia is a multifactorial syndrome characterized by profound involuntary weight loss, fat depletion, skeletal muscle wasting, and asthenia; all symptoms are not entirely attributable to inadequate nutritional intake. Adipose tissue and skeletal muscle loss during cancer cachexia development has been described systematically. The former was proposed to precede and be more rapid than the latter, which presents a means for the early detection of cachexia in cancer patients. Recently, pioglitazone (PGZ) was proposed to exhibit anti-cancer properties, including a reduction in insulin resistance and adipose tissue loss; nevertheless, few studies have evaluated its effect on survival. For greater insight into a potential anti-cachectic effect due to PGZ, 8-week-old male Wistar rats were subcutaneously inoculated with 1 mL (2×107) of Walker 256 tumor cells. The animals were randomly assigned to two experimental groups: TC (tumor + saline-control) and TP5 (tumor + PGZ/5 mg). Body weight, food ingestion and tumor growth were measured at baseline and after removal of tumor on days 7, 14 and 26. Samples from different visceral adipose tissue (AT) depots were collected on days 7 and 14 and stored at -80o C (5 to 7 animals per day/group). The PGZ treatment showed an increase in the survival average of 27.3% (P< 0.01) when compared to TC. It was also associated with enhanced body mass preservation (40.7 and 56.3%, p< 0.01) on day 14 and 26 compared with the TC group. The treatment also reduced the final tumor mass (53.4%, p<0.05) and anorexia compared with the TC group during late-stage cachexia. The retroperitoneal AT (RPAT) mass was preserved on day 7 compared with the TC group during the same experimental period. Such effect also demonstrates inverse relationship with tumor growth, on day 14. Gene expression of PPAR-γ, adiponectin, LPL and C/EBP-α from cachectic rats was upregulated after PGZ. Glucose uptake from adipocyte cells (RPAT) was entirely re-established due to

  7. Predicting changes of body weight, body fat, energy expenditure and metabolic fuel selection in C57BL/6 mice.

    Juen Guo

    Full Text Available The mouse is an important model organism for investigating the molecular mechanisms of body weight regulation, but a quantitative understanding of mouse energy metabolism remains lacking. Therefore, we created a mathematical model of mouse energy metabolism to predict dynamic changes of body weight, body fat, energy expenditure, and metabolic fuel selection. Based on the principle of energy balance, we constructed ordinary differential equations representing the dynamics of body fat mass (FM and fat-free mass (FFM as a function of dietary intake and energy expenditure (EE. The EE model included the cost of tissue deposition, physical activity, diet-induced thermogenesis, and the influence of FM and FFM on metabolic rate. The model was calibrated using previously published data and validated by comparing its predictions to measurements in five groups of male C57/BL6 mice (N = 30 provided ad libitum access to either chow or high fat diets for varying time periods. The mathematical model accurately predicted the observed body weight and FM changes. Physical activity was predicted to decrease immediately upon switching from the chow to the high fat diet and the model coefficients relating EE to FM and FFM agreed with previous independent estimates. Metabolic fuel selection was predicted to depend on a complex interplay between diet composition, the degree of energy imbalance, and body composition. This is the first validated mathematical model of mouse energy metabolism and it provides a quantitative framework for investigating energy balance relationships in mouse models of obesity and diabetes.

    2015-01-01

    Background:This preliminary study examined the effects of an 8-week supervised reactive balance training program on reaction time (RT) and foot speed, static balance and balance confidence in healthy older adults compared to an exercise control group. Methods:Twenty-five older adults were randomly assigned to a reactive balance training group (QuickBoard;n=12;71.0 ± 8.6 years) or a stationary cycling group (control; n = 13; 70.2 ± 6.0 years). Both groups were tested for foot RT foot speed, static balance, and balance confidence at baseline, 4-week, 8-week, and 4-week follow-up. Results: Results indicated significant improvements in QuickBoard foot RT and speed in both groups with greater improvements in the QuickBoard group. However, no group difference was found in static balance performance. Conclusion: Although the improvements in RT and foot speed may be beneficial for fall and trip prevention, the implications of the current findings for trip avoidance and performance of daily tasks are unclear.

    Full Text Available Charles K Herman1,2, Ari S Hoschander3, Nicolas Teleo1, Berish Strauch21Pocono Medical Center/Pocono Health System, East Stroudsburg, PA, 2Albert Einstein College of Medicine, New York, NY; 3Northshore Long Island Jewish Health System, Manhasset, NY, USAAbstract: Surgical treatment for morbid obesity has been increasing over the last few years. Historically, bariatric surgery had been plagued by complications, both technical and metabolic. The criteria to decide if a patient should have bariatric surgery required that the patient’s morbid obesity was contributing to an otherwise imminent demise. Now, with improved techniques, laparoscopic surgery and better understanding of the metabolic consequences of bariatric surgeries, it is presumed that the benefits outweigh the risks of bariatric surgery in increasing numbers of patients. Additionally, the post-bariatric procedures for body contouring have many documented complications. Most of these can be related to the nutritional status of obese patients and the relative immunodeficiency that obese patients possess. After a thorough literature search it appears that bariatric surgery and post-bariatric body contouring are, indeed, safer than previously thought.Keywords: body contouring, gastric bypass, bariatric surgery

  16. Whole-body diffusion-weighted imaging for staging malignant lymphoma in children

    CT is currently the mainstay in staging malignant lymphoma in children, but the risk of second neoplasms due to ionizing radiation associated with CT is not negligible. Whole-body MRI techniques and whole-body diffusion-weighted imaging (DWI) in particular, may be a good radiation-free alternative to CT. DWI is characterized by high sensitivity for the detection of lesions and allows quantitative assessment of diffusion that may aid in the evaluation of malignant lymphomas. This article will review whole-body MRI techniques for staging malignant lymphoma with emphasis on whole-body DWI. Furthermore, future considerations and challenges in whole-body DWI will be discussed. (orig.)

    2015-01-01

    Full Text Available This study intended to investigate whether body weight gain during adulthood is associated with uterine myomas. 1,560 subjects were evaluated in a Pró-Saúde Study. Weight gain was evaluated in a continuous fashion and also in quintiles. Odds ratios and 95% confidence intervals were estimated through logistic regression models that were adjusted for education levels, color/race, body mass indices at age 20, age of menarche, parity, use of oral contraceptive methods, smoking, health insurance, and the Papanicolaou tests. No relevant differences were observed regarding the presence of uterine myomas among weight gain quintiles in that studied population.

  18. Changing Body Image and Well-Being: Following the Experience of Massive Weight Loss and Body Contouring Surgery

    Jo Gilmartin

    2014-03-01

    Full Text Available This paper reports on the perception of changing body image and well-being for patients who had undergone plastic surgery following massive weight loss. The exploratory, qualitative study was undertaken with 20 patients from one teaching hospital in the south of England. Semi-structured interviews were carried out and a thematic analysis of the data undertaken. The results provide important insights regarding body contouring influencing body image change and the adjustment process involved. The ability to pursue self-esteem and the accruing social benefits is emphasized in the interrelated sub themes including social acceptance, undoing depression and sexual vitality. Body contouring surgery following massive weight loss appears to facilitate improvement in body image and well-being. Adjustment to the changing body image is both empowering and challenging. Supportive educational programmes need to be developed to assist this transition to a more positive body image and appreciation; these could usefully include access to and involvement with patient support groups.

  19. Conjugated linoleic acid reduces body weight gain in ovariectomized female C57BL/6J mice

    Kanaya, Noriko; Chen, Shiuan

    2010-01-01

    Estrogen is an important protective factor against obesity in females. Therefore, postmenopausal women have a higher rate of obesity than premenopausal women, which is associated with age-related loss of ovary function. It has been reported that a diet containing conjugated linoleic acid (CLA) reduced body weight and body fat mass in the animal model as well as in human trials. We hypothesized that ingestion of CLA would reduce body weight gain in ovariectomized (OVX) female C57BL/6J mice whi...

  20. Watching reality weight loss TV. The effects on body satisfaction, mood, and snack food consumption.

    2015-08-01

    The present study investigated the influence of a weight loss reality TV show on body satisfaction, mood and food consumption. Young Australian women (N = 99) first completed baseline measures of state body satisfaction and mood. They were then randomly allocated to either a weight loss or a home renovation programme and were provided with snack foods during viewing. Post-measures included state body satisfaction, state mood and trait dietary restraint and snack food consumption. BMI moderated the relationship between condition and body satisfaction and mood. Larger women experienced less body satisfaction and less positive mood in response to the weight loss programme. Dietary restraint moderated the relationship between condition and food consumption. A greater percentage of women with lower dietary restraint ate in the control condition; whilst a greater percentage of women with higher dietary restraint ate food whilst watching the weight loss programme. These findings highlight the potential negative impact of weight-focused reality TV on mood, body satisfaction and snack food consumption among some women. PMID:25936290

  1. Quinine controls body weight gain without affecting food intake in male C57BL6 mice

    Cettour-Rose Philippe

    2013-02-01

    Full Text Available Abstract Background Quinine is a natural molecule commonly used as a flavouring agent in tonic water. Diet supplementation with quinine leads to decreased body weight and food intake in rats. Quinine is an in vitro inhibitor of Trpm5, a cation channel expressed in taste bud cells, the gastrointestinal tract and pancreas. The objective of this work is to determine the effect of diet supplementation with quinine on body weight and body composition in male mice, to investigate its mechanism of action, and whether the effect is mediated through Trpm5. Results Compared with mice consuming AIN, a regular balanced diet, mice consuming AIN diet supplemented with 0.1% quinine gained less weight (2.89 ± 0.30 g vs 5.39 ± 0.50 g and less fat mass (2.22 ± 0.26 g vs 4.33 ± 0.43 g after 13 weeks of diet, and had lower blood glucose and plasma triglycerides. There was no difference in food intake between the mice consuming quinine supplemented diet and those consuming control diet. Trpm5 knockout mice gained less fat mass than wild-type mice. There was a trend for a diet-genotype interaction for body weight and body weight gain, with the effect of quinine less pronounced in the Trpm5 KO than in the WT background. Faecal weight, energy and lipid contents were higher in quinine fed mice compared to regular AIN fed mice and in Trpm5 KO mice compared to wild type mice. Conclusion Quinine contributes to weight control in male C57BL6 mice without affecting food intake. A partial contribution of Trpm5 to quinine dependent body weight control is suggested.

  2. The association of gut microbiota with body weight and body mass index in preschool children of Estonia

    Epp Sepp

    2013-02-01

    Full Text Available Background: The gut microbiota has been shown to affect both fat storage and energy harvesting, suggesting that it plays a direct role in the development of obesity. The aim of this study was to investigate whether intestinal colonization by particular species/groups of the intestinal microbiota is related to body weight values in Estonian preschool children born in different years during the entire 1990s. Methods: Body weight, height, body mass index (BMI, and quantitative composition of cultivable gut microbiota (staphylococci, enterococci, streptococci, enterobacteria, lactobacilli, anaerobic gram-positive cocci, bifidobacteria, eubacteria, bacteroides, clostridia, and candida were studied in 51 healthy 5-year-old children (40 were born between 1993 and 94 and 11 were born between 1996 and 97. Results: At the age of 5 years, median weight was 19.5 kg and median BMI was 15.3 kg/m2. Significantly higher BMI (p=0.006 was found in 5-year-old children born in late versus early 1990s during the development of socioeconomic situation of Estonia (2% rise in gross domestic product. The counts of the different gut bacteria did not show any association with weight and BMI in the 5-year-old children. However, the BMI values were in positive correlation with a relative share of anaerobic gram-positive bacteria, for example, bifidobacteria when adjusted for sex and year of birth (adj R2=0.459, p=0.026 and eubacteria (adj R2=0.484, p=0.014 in the community of cultured intestinal microbiota. The relative share of bacteroides showed a negative correlation with the childrens’ weight (adj R2=− 0.481, p=0.015. Conclusion: The body weight indices of preschool children of the general population are associated with the proportion of anaerobic intestinal microbiota and can be predicted by sex and particular socioeconomic situation from birth to 5 years of age.

    Diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) yields positive results for cancer against the surrounding tissues. The combination of DWIBS and T2-weighted images (DWIBS/T2) in the diagnosis of gastrointestinal tract cancers was retrospectively analyzed in the present study. Patients were subjected to magnetic resonance imaging after cancer was diagnosed through specimens obtained via biopsy or endoscopic mucosal resection. Sixteen patients were assessed between July, 2012 and June, 2013 and the correlation between detection with DWIBS/T2 and T staging was analyzed. Regarding patients who underwent surgery, the correlation between detection with DWIBS/T2 and the diameter or depth of invasion was analyzed. All cancers that had advanced to >T2 stage were detectable by DWIBS/T2, whereas all cancers staged as T2) or invading beyond the muscularis propria.

  5. Can early breastfeeding support increase the 6-8 week breastfeeding prevalence rate?

    Price, Linda

    2014-05-01

    Breastfeeding has significant health benefits for mothers and babies and is an important strategy to reduce health inequalities (UNICEF, 2010). The Baby Friendly Initiative, a strategy to increase breastfeeding rates, has been adopted by the trust. In line with the trust's priorities, the health visiting team initiated a project to increase the 6-8 breastfeeding prevalence rates. Breastfeeding mothers in a defined project area were offered breastfeeding support in their homes within the first postnatal week. Although the results after six months did demonstrate an overall increase in the 6-8 week prevalence rate of 5%, the monthly figures where disappointingly inconsistent and it was difficult to attribute the rise to the increased support offered. Nevertheless, the feedback from mothers who received support demonstrated that it was valued and had a positive impact on their confidence to continue to breastfeed. PMID:24881195

  6. Separating the mink dam from the litter at 7 or 8 weeks after delivery

    Malmkvist, Jens; Palme, Rupert; Larsen, Torben; Hansen, Steffen Werner

    The optimal timing of separating the mink dam from the litter is suggested to be a balance between the partly conflicting needs of the mother and the kits. Early removal of the dam or partial removal of the litter may protect the dam against exhaustion. Little is known about the maternal motivation.......014). Likewise, the dam calls increased on the separation day, peaking on the first day after separation (D1). The proportion of dams with calls decreased with litter age at separation (P=0.024). We interpret these results as a higher maternal motivation in dams at 7 weeks than at 8 weeks after delivery....... Additionally, the amount of dam calls after separation decreased with the litter size (P=0.022). Thus in addition to litter age, the size of the litter is important for the maternal motivation. These factors should, therefore, be taken into account in studies of the optimal separation age in mink....

  7. Ruptured cornual ectopic pregnancy at 8 weeks gestation- successful conservative approach: a case report

    Shobha S. Shiragur

    2013-08-01

    Full Text Available Cornual pregnancy is a rare form of ectopic pregnancy that usually leads to uterine rupture with resultant life threatening hemorrhage. The mortality of interstitial pregnancies is more than twice that of other tubal pregnancies. Cornual pregnancies often rupture later than other tubal pregnancies because the myometrium is more distensible than the fallopian tube. We report a case where a patient presented at 8 weeks of gestational age with ruptured cornual ectopic pregnancy and hemoperitoneum. Emergency Laparotomy was done and cornual rupture was sutured successfully. Close monitoring of pregnancies in these patients is important to prevent a deleterious delay in treatment of a cornual pregnancy. [Int J Reprod Contracept Obstet Gynecol 2013; 2(4.000: 671-673

    Musaiger, Abdulrahman O; Al-Mannai, Mariam

    2013-04-01

    The aim of this study was to find out the association of media and obesity status with body weight concern among female university students in Kuwait. 228 female students, aged 19-25 years, were selected at convenience from the Women's College in Kuwait. A previously validated questionnaire was used to collect information on the role of media in body concern and how parents, peers and the girls themselves perceived girls' body shapes. Weight and height were gathered by self-reporting. Use of internet and reading women's magazines had a significant impact on dieting by the girls to lose weight (Pinfluence on obese girls than non-obese girls. Only watching television had a significant impact on girls' body shape concern (P<0.053). About 30% of non-obese and 81% of obese girls were dissatisfied with their current weight. There were significant differences between obese and non-obese girls regarding the girls' views and the views of their peers and parents about the body weight of the girls (P<0.000 for all). The pressure from peers and parents, in addition to the mass media, may lead to disturbed attitudes towards eating among Kuwaiti girls. PMID:23557827

    Van de Velde, H; Janssens, G P J; Stuyven, E; Cox, E; Buyse, J; Hesta, M

    2012-01-15

    Overweight in dogs is, as in other companion animals, a major risk factor for several metabolic disorders. However, it is not yet known whether immunity is challenged by increased body weight in dogs. The aim of this study was to investigate the effect of a short-term increase in body weight on immunological variables in adult healthy beagle dogs. Sixteen dogs, divided into a control group (CG) and weight gain group (WGG), were included. During a period of 13 weeks, the CG was fed at maintenance energy requirement (MER), whereas the WGG received a double amount of food. After 13 weeks, blood samples were taken for immunological and biochemical analyses. Weight gain and increased body condition score in the WGG were accompanied by a significant higher leptin concentration. Weight gain increased the number of lymphocytes and immunoglobulins A and M and was responsible for a higher proliferation of peripheral blood mononuclear cells (PBMC). Short-term increase of body weight thus seems to trigger immunological variables in dogs. PMID:22245229

  10. Prenatal Centrifugation: A Mode1 for Fetal Programming of Body Weight?

    Baer, Lisa A.; Rushing, Linda; Wade, Charles E.; Ronca, April E.

    2005-01-01

    'Fetal programming' is a newly emerging field that is revealing astounding insights into the prenatal origins of adult disease, including metabolic, endocrine, and cardiovascular pathophysiology. In the present study, we tested the hypothesis that rat pups conceived, gestated and born at 2-g have significantly reduced birth weights and increased adult body weights as compared to 1-g controls. Offspring were produced by mating young adult male and female rats that were adapted to 2-g centrifugation. Female rats underwent conception, pregnancy and birth at 2-g. Newborn pups in the 2-g condition were removed from the centrifuge and fostered to non-manipulated, newly parturient dams maintained at 1 -g. Comparisons were made with 1-g stationary controls, also crossfostered at birth. As compared to 1-g controls, birth weights of pups gestated and born at 2-g were significantly reduced. Pup body weights were significantly reduced until Postnatal day (P) 12. Beginning on P63, body weights of 2-g-gestated offspring exceeded those of 1-g controls by 7-10%. Thus, prenatal rearing at 2-g restricts neonatal growth and increases adult body weight. Collectively, these data support the hypothesis that 2-g centrifugation alters the intrauterine milieu, thereby inducing persistent changes in adult phenotype.

  11. Mechanism of Body Weight Reducing Effect of Oral Boric Acid Intake

    2013-01-01

    Full Text Available Objective. The effect of oral boric acid intake on reducing body weight has been previously demonstrated although the mechanism has been unclear. This research study reveals the mechanism. Subjects. Twelve mice were used, in groups of six each in the control and study groups. For five days, control group mice drank standard tap water while during the same time period the study group mice drank tap water which contains 0.28 mg/250 mL boric acid. After a 5-day period, gene expression levels for uncoupling proteins (UCPs in the white adipose tissue (WAT, brown adipose tissue (BAT, and skeletal muscle tissue (SMT and total body weight changes were analyzed. Results. Real time PCR analysis revealed no significant change in UCP3 expressions, but UCP2 in WAT (: 0.0317, BAT (: 0.014, and SMT (: 0.0159 and UCP1 in BAT (: 0.026 were overexpressed in the boric acid group. In addition, mice in the boric acid group lost body weight (mean 28.1% while mice in the control group experienced no weight loss but a slight weight gain (mean 0.09%, . Conclusion. Oral boric acid intake causes overexpression of thermogenic proteins in the adipose and skeletal muscle tissues. Increasing thermogenesis through UCP protein pathway results in the accelerated lipolysis and body weight loss.

  12. Genetics of microenvironmental sensitivity of body weight in rainbow trout (Oncorhynchus mykiss selected for improved growth.

    Matti Janhunen

    Full Text Available Microenvironmental sensitivity of a genotype refers to the ability to buffer against non-specific environmental factors, and it can be quantified by the amount of residual variation in a trait expressed by the genotype's offspring within a (macroenvironment. Due to the high degree of polymorphism in behavioral, growth and life-history traits, both farmed and wild salmonids are highly susceptible to microenvironmental variation, yet the heritable basis of this characteristic remains unknown. We estimated the genetic (covariance of body weight and its residual variation in 2-year-old rainbow trout (Oncorhynchus mykiss using a multigenerational data of 45,900 individuals from the Finnish national breeding programme. We also tested whether or not microenvironmental sensitivity has been changed as a correlated genetic response when genetic improvement for growth has been practiced over five generations. The animal model analysis revealed the presence of genetic heterogeneity both in body weight and its residual variation. Heritability of residual variation was remarkably lower (0.02 than that for body weight (0.35. However, genetic coefficient of variation was notable in both body weight (14% and its residual variation (37%, suggesting a substantial potential for selection responses in both traits. Furthermore, a significant negative genetic correlation (-0.16 was found between body weight and its residual variation, i.e., rapidly growing genotypes are also more tolerant to perturbations in microenvironment. The genetic trends showed that fish growth was successfully increased by selective breeding (an average of 6% per generation, whereas no genetic change occurred in residual variation during the same period. The results imply that genetic improvement for body weight does not cause a concomitant increase in microenvironmental sensitivity. For commercial production, however, there may be high potential to simultaneously improve weight gain and

    Full Text Available Background: Assessing body image self-perception has used BMI as an indicator of nutritional status. The visual analogue scale is a highly effective instrument for assessing people′s level of dissatisfaction with their body weight while evaluating the perceptual component of body image. Objective: By knowing body mass index of female medical students, to find out their pattern of body image perception and any attempts done to change their weight. Materials and Methods: All the students residing in MBBS ladies hostel were included in this study and a questionnaire regarding body image perception, diet, physical activity and attempts to change weight was instituted. Their responses were collected, tabulated, analyzed and interpreted. Results: Among 147 study subjects, according to BMI, 25(17% were undernourished while 111(75.5% and 11(7.5% were normally nourished and overweight respectively. 35(23.8% of the subjects felt they were lean, 95(64.6% felt they were normal and 17(11.6% felt they were overweight. Regarding image satisfaction, 98(66.7% of them were satisfied with their image and out of 49 who were not satisfied 30 (20.4 % wanted to reduce weight. Skipping meals was practiced by 42 (28.6% of subjects. Conclusion: About 75.5% of the study group were having normal BMI. Most of them perceived their image correctly regarding to their weight. Most of the underweight and all overweight females were not satisfied. Underweight females preferred to gain weight and overweight females preferred to lose weight.

  14. Relationships between fetal body weight of Wistar rats at term and the extent of skeletal ossification

    Full Text Available We investigated the relationship between fetal body weight at term (pregnancy day 21 and the extent of ossification of sternum, metacarpus, metatarsus, phalanges (proximal, medial and distal of fore- and hindlimbs and cervical and coccygeal vertebrae in Wistar rats. The relationships between fetal body weight and sex, intrauterine position, uterine horn, horn size, and litter size were determined using historical control data (7594 fetuses; 769 litters of untreated rats. Relationships between body weight and degree of ossification were examined in a subset of 1484 historical control fetuses (154 litters which were subsequently cleared and stained with alizarin red S. Fetal weight was independent of horn size, uterine horn side (left or right or intrauterine position. Males were heavier than females and fetal weight decreased with increasing litter size. Evaluation of the skeleton showed that ossification of sternum, metacarpus and metatarsus was extensively complete and independent of fetal weight on pregnancy day 21. In contrast, the extent of ossification of fore- and hindlimb phalanges and of cervical and sacrococcygeal vertebrae was dependent on fetal body weight. The strongest correlation between body weight and degree of ossification was found for hindlimb, medial and proximal phalanges. Our data therefore suggest that, in full-term rat fetuses (day 21, reduced ossification of sternum, metacarpus and metatarsus results from a localized impairment of bone calcification (i.e., a malformation or variation rather than from general growth retardation and that ossification of hindlimb (medial and proximal phalanges is a good indicator of treatment-induced fetal growth retardation.

    2014-10-01

    [Purpose] For maximum efficiency and to prevent injury during javelin throwing, it is critical to maintain muscle balance and coordination of the rotator cuff and the glenohumeral joint. In this study, we investigated the change in the rotator cuff muscle strength, throw distance and technique of javelin throwers after they had performed a specific physical training that combined elements of weight training, function movement screen training, and core training. [Subjects] Ten javelin throwers participated in this study: six university athletes in the experimental group and four national-level athletes in the control group. [Methods] The experimental group performed 8 weeks of the specific physical training. To evaluate the effects of the training, measurements were performed before and after the training for the experimental group. Measurements comprised anthropometry, isokinetic muscle strength measurements, the function movement screen test, and movement analysis. [Results] After the specific physical training, the function movement screen score and external and internal rotator muscle strength showed statistically significant increases. Among kinematic factors, only pull distance showed improvement after training. [Conclusion] Eight weeks of specific physical training for dynamic stabilizer muscles enhanced the rotator cuff muscle strength, core stability, throw distance, and flexibility of javelin throwers. These results suggest that specific physical training can be useful for preventing shoulder injuries and improving the performance for javelin throwers. PMID:25364111

    2016-01-01

    Background Fish protein hydrolysates (FPHs) have been reported as a suitable source of proteins for human nutrition because of their balanced amino acid composition and positive effect on gastrointestinal absorption. Objective Here, we investigated the effect of a FPH, Slimpro®, obtained from blue whiting (Micromesistius poutassou) muscle by enzymatic hydrolysis, on body composition and on stimulating cholecystokinin (CCK) and glucagon-like peptide-1 (GLP-1) secretion. Design A randomized clinical study was carried out on 120, slightly overweight (25 kg/m2 ≤ BMIProduct use was associated with a mild hypocaloric diet (−300 kcal/day). Body composition (body weight; fat mass; extracellular water; and circumference of waist, thighs, and hips) and CCK/GLP-1 blood levels were measured at the beginning of the study and after 45 and 90 days of product use. CCK/GLP-1 levels were measured since they are involved in controlling food intake. Results Treated subjects reported an improvement of body weight composition and an increased blood concentration of both CCK and GLP-1. No differences were found between the 1.4 and 2.8 g FPH doses, indicating a plateau effect starting from 1.4 g FPH. Conclusions Both 1.4 and 2.8 g of FPH were effective in improving body composition and in increasing CCK and GLP-1 blood levels. PMID:26829186

    Full Text Available Background: Previous work reported the benefits of extracts of 2 Cameroonian spices – Irvingia gabonensis and Dichrostachys glomerata— on obese people with metabolic syndrome. Considering the physio-metabolic changes that accompany obesity, the present study investigates the effects of these extracts on healthy overweight participants over an 8-week test period. Methods: The study was an 8 week randomized double-blind, placebo controlled design involving 48 overweight (BMI 26 – 30 participants (27 females and 19 males, divided into 3 groups – placebo, 300 mg I. gabonensis extract (IGOB131, or 300 mg D. glomerata extract (DyglomeraTM. Capsules containing the placebo or the test formulations were administered once daily before the main meal of the day. No major dietary changes or changes in physical activity were demonstrated during the study. Weight and blood lipid parameters were measured at baseline, and at the 4 and 8 weeks interval. Results: Compared to the placebo group, there were significant (p<0.05 reductions in weight of participants in both test groups over the 8 week period. However, these significant changes were not observed in the initial 4 weeks, even though the lipid parameters in the test groups changed significantly (p<0.05. Conclusion: The extracts of Irvingia gabonensis and Dichrostachys glomerata, at a dose of 300 mg per day, were effective in reducing weight and positively modifying lipid parameters in healthy overweight participants.

    2004-01-01

    Maximum rate of food consumption (Cmax) was determined for juvenile Sebastodes fuscescens (Houttuyn) at water temperature of 10, 15, 20 and 25℃. The relationships of Cmax to the body weight (W) at each temperature were described by a power equation: lnCmax = a + b lnW. Covariance analysis revealed significant interaction of the temperature and body weight. The relationship of adjusted Cmax to water temperature (T) was described by a quadratic equation: Cmax =-0.369 + 0.456T - 0.0117T2. The optimal feeding temperature calculated from this equation was 19.5℃. The coefficients of the multiple regression estimation relating Cmax to body weight (W) and water temperature (T) were given in the Table 2.

    The effects of body weight and temperature on the carbon budget of the juvenile bastard halibut, Paralichthys olivaceus , were studied at temperature 13.5, 18, 21.5 and 24 ℃, respectively. The carbon intake, faecal and growth carbon were measured, and the carbon respiration was calculated using the carbon budget equation(CC=GC+FC+RC). The combined relationship between different components of the carbon budget, body weight and temperature could be described by regression equations: CC =1.0206 W 0.8126 e 0.1483 T; G=0.0042 W 1.4096 (-5.11 T 3+285.90 T2-5173.72 T +30314.03); FC =0.0485 W0.7711e 0.1624 T ; UC = 1.4333 W 0.6715e 0.1487 T. Body weight had no significant ffect on the carbon absorption efficiency and the conversion efficiency.

    2004-01-01

    Pancreatic polypeptide (PP) is released from the pancreas in response to a meal. In humans, low-circulating PP levels have been observed in obesity, and administration of pharmacological doses of PP has been shown to decrease food intake. The aim of the present study was to investigate whether low...... circulating PP is associated with weight gain in Pima Indians. Plasma PP concentrations were measured after an overnight fast and 30 min after a standardized mixed meal in 33 nondiabetic male subjects who had a follow-up visit 4.9 +/- 2.5 years later. Cross-sectionally, fasting and postprandial PP levels were...... negatively associated with body size and adiposity. Prospectively, the change in PP response to the meal was negatively associated with the change in body weight (r = -0.53, P = 0.002). In contrast, a high fasting PP level was positively associated with change in body weight (r = 0.45, P = 0.009). In...

    2014-01-01

    Full Text Available INTRODUCTION: Adolescence is a period characterized by changes such as accelerated physical growth and sexual development. Besides having to deal with these changes, adolescents are faced with beauty standards and extreme valorization of physical appearance. OBJECTIVE: This article aims to describe body image and the practice of extreme attitudes regarding weight in Brazilian students. METHODS: Data from the National Survey of School Health (PeNSE 2012 were used in this study. PeNSE 2012 has a representative sample of students in the 9th grade of elementary school in public and private schools across the country. A self-administered questionnaire on body image, practice of extreme measures in relation to weight and sociodemographic data was used. Body image and the practice of extreme attitudes were described for the total sample and according to gender. Poisson regression analyzes were used to identify differences in the practices of extreme attitudes between the different types of body image. RESULTS: More than 38% of the adolescents did not consider their body image as normal. Over 15% of the students referred to carry out extreme weight control practices, combining practices to loose and gain weight. Adolescents who considered themselves fat presented frequency of extreme practices for weight loss 92% higher than that shown by individuals who considered themselves normal. Similarly, adolescents who considered themselves thin presented frequency of extreme attitudes to gain weight (9.7% higher than that shown by students who considered themselves normal (5.6%. CONCLUSIONS: The high frequency of extreme weight control practices among Brazilian adolescents is alarming and should be subject of measures in health and education fields.

  11. Reduced body weight is a common effect of gene knockout in mice

    Lawler Maureen P

    2008-01-01

    Full Text Available Abstract Background During a search for obesity candidate genes in a small region of the mouse genome, we noticed that many genes when knocked out influence body weight. To determine whether this was a general feature of gene knockout or a chance occurrence, we surveyed the Jackson Laboratory Mouse Genome Database for knockout mouse strains and their phenotypes. Body weights were not available for all strains so we also obtained body weight information by contacting a random sample of investigators responsible for a knockout strain. Results We classified each knockout mouse strain as (1 lighter and smaller, (2 larger and heavier, or (3 the same weight, relative to control mice. We excluded knockout strains that died early in life, even though this type of lethality is often associated with a small embryo or reduced body size. Based on a dataset of 1,977 knockout strains, we found that that 31% of viable knockout mouse strains weighed less and an additional 3% weighed more than did controls. Conclusion Body weight is potentially a latent variable in about a third of experiments that use knockout mice and should be considered in interpreting experimental outcomes, e.g., in studies of hypertension, drug and hormone metabolism, organ development, cell proliferation and apoptosis, digestion, heart rate, or atherosclerosis. If we assume that the knockout genes we surveyed are representative then upward of 6,000 genes are predicted to influence the size of a mouse. Body weight is highly heritable, and numerous quantitative trait loci have been mapped in mice, but "multigenic" is an insufficient term for the thousands of loci that could contribute to this complex trait.

    2012-06-01

    Full Text Available The aim of this research is to analyse the semen of different breeds of rabbits and to determine the effects of age, breed, sire, generation and body weight on the ejaculate characteristics of rabbit bucks. Twenty rabbit bucks comprising of three breeds (New-Zealand White 8, Chinchilla 6 and Californian White 6 between the ages of 6-9 months were used to investigate the effect of age, breed, sire and generation on body weight and ejaculate characteristics of the bucks. The experiment was carried out at the Animal Science departmental farm, Ahmadu Bello University, Zaria. Parameters considered include semen colour, semen volume, semen ejaculate volume, semen concentration, semen pH, sperm motility, body weight and age. The mean for semen ejaculate volume, semen concentration, pH, sperm motility, body weight and age were 0.5 mL, 325.5x106 sperm cells/mL, 7.5, 86.6, 2.0 and 7.6% months, respectively. Age, breed and sire had (p≤0.05 effect on ejaculate characteristics but breed and sire had higher significant (p<0.01 effect on body weight. However, generation had no significant effect on the body weight and ejaculate characteristics except on semen pH (p<0.05. The ejaculate characteristics of the rabbit bucks were influenced by age, breed and sire. The values obtained were within the normal standards for rabbits-bucks. New Zealand White bucks proved superior in terms of ejaculate characteristics.

  13. Liver volume in thalassaemia major: relationship with body weight, serum ferritin, and liver function

    It is not known whether body weight alone can adjust for the volume of liver in the calculation of the chelating dose in {beta}-thalassaemia major patients, who frequently have iron overload and hepatitis. The hypothesis is that liver volume in children and adolescents suffering from {beta}-thalassaemia major is affected by ferritin level and liver function. Thirty-five {beta}-thalassaemia major patients aged 7-18 years and 35 age- and sex-matched controls had liver volume measured by MRI. Serum alanine aminotransferase (ALT) and ferritin levels were obtained in the thalassaemia major patients. Body weight explained 65 and 86% of the change in liver volume in {beta}-thalassaemia major patients and age-matched control subjects, respectively. Liver volume/kilogram body weight was significantly higher (P<0.001) in thalassaemia major patients than in control subjects. There was a significant correlation between ALT level and liver volume/kilogram body weight (r=0.55, P=0.001). Patients with elevated ALT had significantly higher liver volume/kilogram body weight (mean 42.9{+-}12 cm{sup 3}/kg) than control subjects (mean 23.4{+-}3.6 cm{sup 3}/kg) and patients with normal ALT levels (mean 27.4{+-}3.6 cm{sup 3}/kg). Body weight is the most important single factor for liver-volume changes in thalassaemia major patients, but elevated ALT also has a significant role. Direct liver volume measurement for chelation dose adjustment may be advantageous in patients with elevated ALT. (orig.)

    2015-02-01

    Full Text Available OBJECTIVES: To investigate the prevalence of excess body weight in the pediatric ward of University Hospital and to test both the association between initial nutritional diagnosis and the length of stay and the in-hospital variation in nutritional status. METHODS: Retrospective cohort study based on information entered in clinical records from University Hospital. The data were collected from a convenience sample of 91 cases among children aged one to 10 years admitted to the hospital in 2009. The data that characterize the sample are presented in a descriptive manner. Additionally, we performed a multivariate linear regression analysis adjusted for age and gender. RESULTS: Nutritional classification at baseline showed that 87.8% of the children had a normal weight and that 8.9% had excess weight. The linear regression models showed that the average weight loss z-score of the children with excess weight compared with the group with normal weight was −0.48 (p = 0.018 and that their length of stay was 2.37 days longer on average compared with that of the normal-weight group (p = 0.047. CONCLUSIONS: The length of stay and loss of weight at the hospital may be greater among children with excess weight than among children with normal weight.

  7. Nutraceuticals for body-weight management: The role of green tea catechins.

    Janssens, Pilou L H R; Hursel, Rick; Westerterp-Plantenga, Margriet S

    2016-08-01

    Green tea catechins mixed with caffeine have been proposed as adjuvants for maintaining or enhancing energy expenditure and for increasing fat oxidation, in the context of prevention and treatment of obesity. These catechins-caffeine mixtures seem to counteract the decrease in metabolic rate that occurs during weight loss. Their effects are of particular importance during weight maintenance after weight loss. Other metabolic targets may be fat absorption and the gut microbiota composition, but these effects still need further investigation in combination with weight loss. Limitations for the effects of green tea catechins are moderating factors such as genetic predisposition related to COMT-activity, habitual caffeine intake, and ingestion combined with dietary protein. In conclusion, a mixture of green tea catechins and caffeine has a beneficial effect on body-weight management, especially by sustained energy expenditure, fat oxidation, and preservation of fat free body-mass, after energy restriction induced body-weight loss, when taking the limitations into account.

    Full Text Available ABSTRACT: Objective: To assess the association between body weight concern and their frequency of exposure to the media among a group of young girls. Methods: A cross sectional study was conducted of 110 girls aged 14-21 years, residing in the district of Howrah, West Bengal. Information on socio-demographic characteristics, weight related concern and media exposures were collected using pretested questionnaires. Weight related concerns included body weight dissatisfaction and perceived body weight. Media exposures included frequency of watching television programs, reading newspaper and magazine articles and browsing internet on topics related to body weight concern. Results: Although the frequency of watching television programs was high among the study participants yet it was not significantly associated with their body weight. Ch-square test showed that there was an association between the frequency of exposure to magazine articles related to body weight concern and initiation of exercise to reduce body weight. Reading of newspaper articles related to body weight by the participants was significantly associated with those who perceive themselves as fat. Multinomial logistic regression analysis revealed that the perception of being overweight was found to be four times more among the girls below 17 years compared to those who are older. Conclusions: Print media (both news paper and magazine did play a significant role in developing concerns over body weight among this group of young girls.

    2016-07-01

    Aster spathulifolius Maxim (AS), a perennial herb of the genus Aster within the family Asteraceae, induced weight loss in a rat model of diet-induced obesity. We hypothesized that AS could also reduce body weight in obese humans. Therefore, we performed a randomized, double-blind, placebo-controlled clinical trial in Korea to evaluate the effect of AS extract (ASE) on body weight and fat mass and its safety in obese humans. Forty-four obese participants (body mass index [BMI], 25-30 kg/m(2)) aged ≥20 years were randomly assigned to the placebo or ASE group (700 mg/d of ASE) and were instructed to take a once-daily pill for 12 weeks. Weight, BMI, waist circumference, fat mass (measured using bioimpedance, dual-energy X-ray absorptiometry, and computed tomography), and laboratory tests were assessed at baseline and at 12 weeks. Body weight significantly decreased after 12 weeks of treatment in the ASE group (placebo vs ASE: -0.08 ± 2.11 kg vs -3.30 ± 3.15 kg, P bioimpedance method: -0.51 ± 1.89 kg vs -2.38 ± 2.30 kg, P < .05; dual-energy X-ray absorptiometry: 0.38 ± 1.59 kg vs -2.26 ± 2.37 kg, P < .05). Changes in lipid profiles, fasting plasma glucose, and hemoglobin A1c did not differ between the 2 groups. No drug-related adverse events were observed during the study. In conclusion, ASE significantly decreases body weight and fat mass in obese humans, suggesting that ASE may be a potential therapeutic candidate for reducing obesity. PMID:27333958

  15. On-farm estimation of energy balance in dairy cows using only frequent body weight measurements and body condition score

    Thorup, Vivi Mørkøre; Edwards, David; Friggens, N C

    2012-01-01

    Precise energy balance estimates for individual cows are of great importance to health, reproduction and feed management. Energy balance is usually calculated as energy input minus output (EBalinout), requiring measurements of feed intake and energy output sources (milk, maintenance, activity......, growth and pregnancy). Except milk yield, direct measurements of these are difficult to obtain in practice, and estimates involve considerable error sources, so limiting on-farm use. Alternatively, energy balance can be estimated from body reserve changes (EBalbody) using body weight (BW) and body....... Further, the FEC profile did not suggest any systematic bias in EBalbody with stage of lactation. Moreover we successfully modeled EBalbody differences between breeds, parities and diets. For the farmer, the ability to predict energy balance for individual cows on-farm without having to measure feed...

  16. Weight Misperceptions and Racial and Ethnic Disparities in Adolescent Female Body Mass Index

    Ramona C. Krauss

    2012-01-01

    Full Text Available This paper investigated weight misperceptions as determinants of racial/ethnic disparities in body mass index (BMI among adolescent females using data from the National Survey of Youth 1997. Compared to their white counterparts, higher proportions of black and Hispanic adolescent females underperceived their weight status; that is, they misperceived themselves to have lower weight status compared to their clinically defined weight status. Compared to their black counterparts, higher proportions of white and Hispanic adolescent females misperceived themselves to be heavier than their clinical weight status. Oaxaca-Blinder decomposition analysis showed that accounting for weight misperceptions, in addition to individual and contextual factors, increased the total explained portion of the black-white female BMI gap from 44.7% to 54.3% but only slightly increased the total explained portion of the Hispanic-white gap from 62.8% to 63.1%. Weight misperceptions explained 13.0% of the black-white female BMI gap and 3.3% of the Hispanic-white female BMI gap. The regression estimates showed that weight underperceptions were important determinants of adolescent female BMI, particularly among black and Hispanic adolescents. Education regarding identification and interpretation of weight status may play an important role to help reduce the incidence and racial disparity of female adolescent obesity.

    2016-01-01

    The inability ofFenneropenaeus chinensis to tolerate low temperatures is of major economic concern in temperate climates, as it reduces their growing season and leads to over-winter mortality. In this study, the heritability of body weight under low grow-out temperature and cold tolerance inF. chinensis were first investigated and estimated using 88 ful-sib families, which might provide crucial information in Chinese fleshy prawn breeding programs. The heritability for body weight under suitable and low temperature ofF. chinensis were both moderate (0.158 0±0.307 5 and 0.132 0±0.026 9 respectively); the large coefficient of variation (approximately 21%) and moderate estimate of heritability for body weight indicated substantial potential for selective breeding. The heritability estimate for cold tolerance was low (0.019 2±0.023 5), and showed no significant differences from zero (P>0.05). A weak genetic correlation between cold tolerance and body weight was also estimated in the present study, also showing no significant differences from zero (P>0.05). Thus, more research needs to be conducted on the more accurate heritability estimate of cold tolerance and genetic correlations between traits inF. chinensis to further improve the achievement of breeding goals.

    Full Text Available Purpose : The research examined the relationship between body weight satisfaction and disordered eating among youth who are active in sport in Singapore. Method : 137 youths (82 boys and 55 girls; age 12-13 enrolled in school sport completed two self-report questionnaires- SCOFF for disordered eating and body weight satisfaction- on two separate occasions that were six months apart (T1 vs. T2. Results : Body mass index for age classifications revealed that 5.1% were severely underweight; 1.5% underweight; 88.3% acceptable weight; 4.4% overweight and 0.7% were severely overweight. Conclusions : (i the prevalence of disordered eating was 46% at baseline measurement and this remained stable at 45.3% six months later; (ii there was no sex difference for disordered eating on the two measurement occasions (T1 vs. T2, p>0.05; (iii the prevalence of youths unsure of their bodyweight satisfaction was 26.6-21.2% which compared to 88.3% adjudged to be of healthy weight; across T1 and T2, more male subjects wanted to gain bodyweight while more female subjects wanted to lose bodyweight; and (iv subjects who were dissatisfied with their bodyweight had significantly greater odds of being at risk for developing DE. Holistic education programmes based upon body image and nutrition, are recommended.

    2005-02-01

    (1) Genetic parameters for the sudden death syndrome (SDS) were estimated in meat-type chickens. Data were collected over 11 generations of selection for body weight within two distinct breeds (Cornish and White Rock). (2) The animal model was used exclusively with linear methods (LM) to estimate genetic parameters. Heritability (h2) of SDS on the liability scale was 0.30 +/- 0.002 and 0.25 +/- 0.002 in the Cornish and White Rock breeds, respectively. (3) A positive genetic correlation (r(g)) with ascites (AS) was determined (approximately 0.3 +/- 0.006). However, it was not possible to estimate the rg of SDS with body weight because of the low prevalence of the defect trait studied (1.8% in the Cornish and 1-5% in the White Rock). (4) Heritability of SDS calculated using male records only was 0.45 +/- 0.009 and 0.35 +/- 0.009, and r(g) with body weight was 0.30 +/- 0.010 and 0.27 +/- 0.009, in the Cornish and White Rock breeds, respectively. (5) In conclusion, the heart defect investigated was heritable with a positive genetic correlation with AS and body weight. PMID:15835252

  8. Liver volume in thalassaemia major: relationship with body weight, serum ferritin, and liver function

    It is not known whether body weight alone can adjust for the volume of liver in the calculation of the chelating dose in β-thalassaemia major patients, who frequently have iron overload and hepatitis. The hypothesis is that liver volume in children and adolescents suffering from β-thalassaemia major is affected by ferritin level and liver function. Thirty-five β-thalassaemia major patients aged 7-18 years and 35 age- and sex-matched controls had liver volume measured by MRI. Serum alanine aminotransferase (ALT) and ferritin levels were obtained in the thalassaemia major patients. Body weight explained 65 and 86% of the change in liver volume in β-thalassaemia major patients and age-matched control subjects, respectively. Liver volume/kilogram body weight was significantly higher (P3/kg) than control subjects (mean 23.4±3.6 cm3/kg) and patients with normal ALT levels (mean 27.4±3.6 cm3/kg). Body weight is the most important single factor for liver-volume changes in thalassaemia major patients, but elevated ALT also has a significant role. Direct liver volume measurement for chelation dose adjustment may be advantageous in patients with elevated ALT. (orig.)

    Minooee, Sonia; Ramezani Tehrani, Fahimeh; Mirmiran, Parvin; Azizi, Fereidoun

    2016-01-01

    Background: Women engaged with polycystic ovarian syndrome (PCOS), as the commonest endocrine disorder, are known to have a specific type of adiposity. Birth weight is among different contributors reported to be responsible for this diversity. Objective: We aimed to compare the relation between birth weight and body fat mass (BFM)/ body lean mass (BLM) in PCOS and their age and body mass index (BMI) matched normal controls. Materials and Methods: In this case-control study, a total number of 70 reproductive aged women, diagnosed with PCOS and 70 age- BMI matched healthy women without hirsutism and/or ovulatory dysfunction were recruited., control group had no polycystic ovaries in ultrasonographic scans. A detailed history of birth weight was taken and was divided into the following categories: PCOS than in controls (19.3% (27) vs. 15.7% (22)). Also body fat and lean mass (BFM, BLM) have increased in adult women with PCOS who were born underweight compared to their normal (19.8±9.05 vs. 12.9±4.5, p=0.001 and 48.9±6.9 vs. 43.2±5.8, p=0.004 respectively). Conclusion: Fetal birth weight influences on the adulthood obesity, BFM and BLM. This impact is different among women with and without PCOS. PMID:27326419

    Artificial sweeteners are widely used all over the world. They may assist in weight management, prevention of dental caries, control of blood glucose of diabetics, and also can be used to replace sugar in foods. In the animal experimentation mice were given oral doses of water solutions of table top artificial sweeteners (saccharin, cyclamate based, acesulfame-K based, and aspartame) the amount of maximum Acceptable Daily Intake (ADI) ad libitum. The controls received only tap water with the same drinking conditions as the treated groups. The mice were fed chow ad libitum.We measured food intake and body weight once a week, water and solutions of artificial sweeteners intake twice a week. The data were analysed by statistical methods (T-probe, regression analysis).Consumption of sweeteners resulted in significantly increased body weight; however, the food intake did not change.These results question the effect of non-caloric artificial sweeteners on weight-maintenance or body weight decrease.

    Regulating the energy density of food could be used as a novel approach for successful body weight reduction in clinical practice. The aim of this study was to conduct a systemic review of the literature on the relationship between food energy density and body weight changes in obese adults to obtain solid evidence supporting this approach. The search process was based on the selection of publications in the English language listed in public databases. A meta-analysis was performed to combine individual study results. Thirteen experimental and observational studies were identified and included in the final analysis. The analyzed populations consist of 3628 individuals aged 18 to 66 years. The studies varied greatly in terms of study populations, study design and applied dietary approaches. The meta-analysis revealed a significant association between low energy density foods and body weight reduction, i.e., -0.53 kg when low energy density foods were eaten (95% CI: -0.88, -0.19). In conclusions, this study adds evidence which supports the energy density of food as a simple but effective measure to manage weight in the obese with the aim of weight reduction. PMID:27104562

  14. For Researchers on Obesity: Historical Review of Extra Body Weight Definitions

    Komaroff, Marina

    2016-01-01

    Rationale. The concept of obesity has been known since ancient world; however, the current standard definition of obesity was endorsed only about a decade ago. There is a need for researches to understand multiple approaches to defining obesity and how and why the standard definition was developed. The review will help to grasp the complexity of the problem and can lead to novel hypotheses in obesity research. Objective. This paper focuses on the objective to understand historical background on the development of “reference and standard tables” of weight as a platform for normal versus abnormal body weight definition. Methods. A systematic literature review was performed to chronologically summarize the definition of body weight from time of Hippocrates till the year of 2010. Conclusion. This paper presents the historical background on the development of “reference and standard tables” of weight as a platform for normal versus abnormal body weight definition. Knowledge of historical approaches to the concept of obesity can motivate researchers to find new hypotheses and utilize the appropriate obesity assessments to address their objectives.

    2010-01-01

    Levels of full-length huntingtin (FL htt) influence organ and body weight, independent of polyglutamine length. The growth hormone-insulin like growth factor-1 (GH-IGF-1) axis is well established as a regulator of organ growth and body weight. In this study, we investigate the involvement...... of the IGF-1 pathway in mediating the effect of htt on body weight. IGF-1 expression was examined in transgenic mouse lines expressing different levels of FL wild-type (WT) htt (YAC18 mice), FL mutant htt (YAC128 and BACHD mice) and truncated mutant htt (shortstop mice). We demonstrate that htt influences...... body weight by modulating the IGF-1 pathway. Plasma IGF-1 levels correlate with body weight and htt levels in the transgenic YAC mice expressing human htt. The effect of htt on IGF-1 expression is independent of CAG size. No effect on body weight is observed in transgenic YAC mice expressing...

  19. Cues of High and Low Body Weight Negatively Influence Adults' Perceptions and Ratings in the Hypothetical Adoption Paradigm

    Anthony A. Volk

    2006-01-01

    Full Text Available Infant and child facial cues influence perceptions and ratings in the Hypothetical Adoption Paradigm as well as actual parental care. A previous study demonstrated that infant and child facial cues of low body weight negatively influenced adults' ratings. The current study sought to replicate and expand on those results by presenting adults with normal faces as well as faces that were digitally altered to display high or low body weight. Cues of abnormal body weight significantly, and negatively, influenced adults’ ratings of adoption preference, health, and cuteness. Effect sizes were larger for cues of high body weight. Thus, infant and child facial cues of abnormal body weight may represent a relative risk factor to the quality of adult care obtained by children with abnormal body weight.

    Diffusion-weighted magnetic resonance imaging (DWI) provides qualitative and quantitative information about the random motion of water molecules in biological tissues and is able to give functional insight into tissue architecture and pathological changes on a cellular level. This technique has the major advantages of not requiring the administration of contrast agents and not exposing the patient to ionizing radiation. Recent technological advances have led to the development of diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) that allows screening of the whole body in 25 minutes. DWI and DWIBS have both revealed great potential in the field of oncology and proved to be useful for detecting and characterizing tumors and evaluating treatment response. This article reviews the basic principles and experimental setup of DWI and DWIBS and illustrates its potential application to the assessment of extracranial tumors. In addition, current limitations and challenges of this promising imaging procedure are discussed. (orig.)

  1. Gestational weight gain and body mass index in children: results from three german cohort studies.

    Andreas Beyerlein

    Full Text Available INTRODUCTION: Previous studies suggested potential priming effects of gestational weight gain (GWG on offspring's body composition in later life. However, consistency of these effects in normal weight, overweight and obese mothers is less clear. METHODS: We combined the individual data of three German cohorts and assessed associations of total and excessive GWG (as defined by criteria of the Institute of Medicine with offspring's mean body mass index (BMI standard deviation scores (SDS and overweight at the age of 5-6 years (total: n = 6,254. Quantile regression was used to examine potentially different effects on different parts of the BMI SDS distribution. All models were adjusted for birth weight, maternal age and maternal smoking during pregnancy and stratified by maternal pre-pregnancy weight status. RESULTS: In adjusted models, positive associations of total and excessive GWG with mean BMI SDS and overweight were observed only in children of non- overweight mothers. For example, excessive GWG was associated with a mean increase of 0.08 (95% CI: 0.01, 0.15 units of BMI SDS (0.13 (0.02, 0.24 kg/m(2 of 'real' BMI in children of normal-weight mothers. The effects of total and excessive GWG on BMI SDS increased for higher- BMI children of normal-weight mothers. DISCUSSION: Increased GWG is likely to be associated with overweight in offspring of non-overweight mothers.

    Full Text Available The objective of the present randomized, open-label, naturalistic 8-week study was to compare the efficacy and safety of treatment with clonazepam (N = 63 and paroxetine (N = 57 in patients with panic disorder with or without agoraphobia. Efficacy assessment included number of panic attacks and clinician ratings of the global severity of panic disorders with the clinical global impression (CGI improvement (CGI-I and CGI severity (CGI-S scales. Most patients were females (69.8 and 68.4% in the clonazepam and paroxetine groups, respectively and age (mean ± SD was 35.9 ± 9.6 years for the clonazepam group and 33.7 ± 8.8 years for the paroxetine group. Treatment with clonazepam versus paroxetine resulted in fewer weekly panic attacks at week 4 (0.1 vs 0.5, respectively; P < 0.01, and greater clinical improvements at week 8 (CGI-I: 1.6 vs 2.9; P = 0.04. Anxiety severity was significantly reduced with clonazepam versus paroxetine at weeks 1 and 2, with no difference in panic disorder severity. Patients treated with clonazepam had fewer adverse events than patients treated with paroxetine (73 vs 95%; P = 0.001. The most common adverse events were drowsiness/fatigue (57%, memory/concentration difficulties (24%, and sexual dysfunction (11% in the clonazepam group and drowsiness/fatigue (81%, sexual dysfunction (70%, and nausea/vomiting (61% in the paroxetine group. This naturalistic study confirms the efficacy and tolerability of clonazepam and paroxetine in the acute treatment of patients with panic disorder.

    Background: Lead exposure is associated with low birth-weight. The objective of this study is to determine whether lead exposure is associated with lower body weight in children, adolescents and adults. Methods: We analyzed data from NHANES 1999–2006 for participants aged ≥ 3 using multiple logistic and multivariate linear regression. Using age- and sex-standardized BMI Z-scores, overweight and obese children (ages 3–19) were classified by BMI ≥ 85th and ≥ 95th percentiles, respectively. The adult population (age ≥ 20) was classified as overweight and obese with BMI measures of 25–29.9 and ≥ 30, respectively. Blood lead level (BLL) was categorized by weighted quartiles. Results: Multivariate linear regressions revealed a lower BMI Z-score in children and adolescents when the highest lead quartile was compared to the lowest lead quartile (β (SE) = − 0.33 (0.07), p < 0.001), and a decreased BMI in adults (β (SE) = − 2.58 (0.25), p < 0.001). Multiple logistic analyses in children and adolescents found a negative association between BLL and the percentage of obese and overweight with BLL in the highest quartile compared to the lowest quartile (OR = 0.42, 95% CI: 0.30–0.59; and OR = 0.67, 95% CI: 0.52–0.88, respectively). Adults in the highest lead quartile were less likely to be obese (OR = 0.42, 95% CI: 0.35–0.50) compared to those in the lowest lead quartile. Further analyses with blood lead as restricted cubic splines, confirmed the dose-relationship between blood lead and body weight outcomes. Conclusions: BLLs are associated with lower body mass index and obesity in children, adolescents and adults. - Highlights: • NHANES analysis of BLL and body weight outcomes • Increased BLL associated with decreased body weight in children and adolescent • Increased BLL associated with decreased body weight in adults.

    2008-01-01

    Objective To evaluate the feasibility of whole body diffusion weighted imaging (DWI) in the diagnosis of metastatic tumor.Methods Fifty-six patients (40 males and 16 females, age ranging from 29 to 84 years with a mean age of 57 years) with a variety of primary tumors were investigated by whole body DWI combined with computed tomography (CT) and/or conventional magnetic resonance imaging (MRI) scans. Twelve patients underwent positron emission tomography. The final diagnosis was made on the basis of CT or high resolution CT result for lung lesion and MRI or CT result for skull, abdomen and other parts. All tumors were classified into four groups by their diameter: below 1.0 cm, 1.0-1.9 cm, 2.0-2.9 cm, and above 3.0 cm. The sensitivity and specificity of whole body DWI in the detection of metastatic tumor were analyzed.Results The sensitivities of whole body DWI for screening metastasis oftlie four groups were 38%, 75%, 97%, and 100%, respectively. Whole body DWI showed the highest sensitivity and specificity for detecting metastasis of the skeletal system. It was difficult to find metastatic tumor whose diameter was below 1.0 cm, or lymph nodes located in the pelvis with diameter below 2.0 cm. Conclusions Whole body DWI is a promising method in the diagnosis ofmetastastic tumors. With the perfection of scanning parameter, whole body DWI should be a new effective whole body technique for tumor detection.

  8. An adaptive diffusion-weighted whole-body magnetic resonance imaging scheme using the multistation approach

    Han, Yeji

    2016-02-01

    Whole-body diffusion-weighted imaging (DWI) is a useful tool in oncology, which enables fast screening of disseminated tumors, lymph nodes or abscesses in the body. Multistation magnetic resonance imaging (MRI) or continuously moving table (CMT) MRI can be performed to overcome the limited field of view (FOV) of the magnet bore in whole-body DWI. Although CMT-MRI is regarded as a more advanced form of whole-body MRI, it cannot be widely used because most of the available MR systems are not equipped with the required hardware/software to perform CMT. Thus, optimizing the multistation approach for whole-body DWI, which is more widely available and easier to perform with the existing MR systems, is worthwhile. To improve the quality of DW images acquired with the multistation approach, we used different combinations of the built-in body RF coil and the phased-array surface RF coils for reception of the signals in whole-body DWI in this work. If different coils are selectively used in the extended FOV and appropriate reconstruction algorithms are exploited, the screening ability of whole-body DWI can be improved while minimizing the patient's discomfort and the artifacts due to physiological motions.

    2014-11-01

    Full Text Available Objective: Parents take an important role in a child's development, but there is currently limited information on parental correlates with children's health behaviour. The purpose of this study, therefore, was to examine whether parental characteristics, such as body weight, TV consumption and sport participation, affect children's body weight and health behaviour. Methods: To examine the effects of parental characteristics on children's body weight and health behaviour, baseline data of 1,118 elementary school children (7.6 ± 0.4 years participating in a school-based intervention in southwest Germany was used. Children's height and weight were measured and parent as well as child behaviour was assessed via questionnaire. Results: BMI percentiles of children were positively associated with parental BMI (r = 0.2, p mother = 2.2, ORfather = 2.3 and parental club sport participation increased the odds for club sport participation in children (ORmother = 1.9, ORfather = 1.7. The relationship between parental and child behaviour was stronger than the relationship between parental BMI and BMI percentiles of the child. Conclusion: These results suggest that parental behaviour and role modelling provide an important contribution to childrens' health behaviour, especially at younger ages.

    Objective To investigate the effects of prenatal exposure to lipopolysaccharide (LPS) on blood pressure and body weight of offspring in rats. Methods Sixteen healthy pregnant rats were randomly divided into two groups. The rats in LPS group were injected intraperitoneally with LPS (0.79 mg·kg-1) at the 8th, 10th, 12th day of gestation. Those in the control group were only treated with NS. After delivery, all offspring were weighed and blood pressure was measured by tail-cuff method once every two weeks from the 6th to 24th week. In the 15th week, their food intakes were weighed every day. At the end of the 24th week, the rats were put to death by decapitation. Abdominal adipose tissues were taken to weigh, and serum level of leptin was detected by RIA. Results The offspring with prenatal LPS exposure showed increased systemic arterial pressure, heavier body weight, elevated food intake, increased adipose tissue weight and increased circulating leptin compared with controls. Conclusions Prenatal exposure to LPS leads to increases in blood pressure and body weight in rats.

    Aim: To investigate the effects of prenatal exposure to lipopolysacchadde (LPS) on blood pressure and body weight of offspring in rats. Methods: Sixteen healthy,pregnant rats were randomly divided into 2 groups. The rats in the LPS group were injected intraperitoneally with LPS (0.79 mg/kg) on the d 8, d 10, and d 12 of gestation. Those in the control group were only treated with normal saline. After delivery, all offspring were weighed and blood pressure was measured by the tail-cuff method once every 2 weeks from the 6th to the 24th week. In the 15th week,their food intake was weighed every day. At the end of the 24th week, the rats were killed by decapitation. Abdominal adipose tissues were weighed, and the serum level of leptin was detected by radioimmunoassay. Results: The offspring with prenatal LPS exposure showed increased systemic arterial pressure, heavier body weight, elevated food intake, increased adipose tissue weight, and increased circulating leptin compared with the controls. Conclusion: Prenatal exposure to LPS leads to increases in blood pressure and body weight in rats.

  12. Standardization and validation of the body weight adjustment regression equations in Olympic weightlifting.

    Kauhanen, Heikki; Komi, Paavo V; Häkkinen, Keijo

    2002-02-01

    The problems in comparing the performances of Olympic weightlifters arise from the fact that the relationship between body weight and weightlifting results is not linear. In the present study, this relationship was examined by using a nonparametric curve fitting technique of robust locally weighted regression (LOWESS) on relatively large data sets of the weightlifting results made in top international competitions. Power function formulas were derived from the fitted LOWESS values to represent the relationship between the 2 variables in a way that directly compares the snatch, clean-and-jerk, and total weightlifting results of a given athlete with those of the world-class weightlifters (golden standards). A residual analysis of several other parametric models derived from the initial results showed that they all experience inconsistencies, yielding either underestimation or overestimation of certain body weights. In addition, the existing handicapping formulas commonly used in normalizing the performances of Olympic weightlifters did not yield satisfactory results when applied to the present data. It was concluded that the devised formulas may provide objective means for the evaluation of the performances of male weightlifters, regardless of their body weights, ages, or performance levels.

  13. Level of satiety: In vitro energy metabolism in brain during hypophagic and hyperphagic body weight recovery

    Rates of in vitro glucose and fatty acid oxidation were examined in four brain sites during hypophagic and hyperphagic recovery of normal body weight. Rats were fed 40, 100, or 160% of normal intake, via gastric intubation, for 3 wk. Another group of rats was starved until body weight loss was equivalent to weight loss in 40%-fed rats. Groups of rats were killed at the conclusion of tube feeding or fasting and at specific periods during recovery of body weight. Brain sites examined were the ventrolateral hypothalamus (VLH), ventromedial hypothalamus (VMH), a caudal brain stem site encompassing the area postrema-nucleus of the solitary tract (AP-NTS), and cortex. During recovery, rats previously fed 160% of normal intake (anorectic) maintained low rates of VLH fatty acid oxidation and were hypophagic until most excess fat was depleted. Conversely, rats previously fed 40% of normal intake (hungry) maintained high rates of VLH fatty acid oxidation and were hyperphagic until most deficient fat was repleted. Rats previously starved maintained high rates of VLH fatty acid oxidation during hyperphagic recovery, although levels of VLH fatty acid oxidation and food intake were initially low on refeeding. Rates of glucose oxidation in the brain sites examined did not relate well to energy balance status and the needed adjustments in food intake. The results indicated that the level of glucose oxidation in the VLH and AP-NTS responded to the level of energy immediately coming into the system (food intake)

    2014-06-01

    Polaprezinc (zinc L-carnosine complex) is a tablet commonly prescribed for gastric ulcers in Japan. Recently, we reported the effects of polaprezinc on pressure ulcer healing at 4-week follow-up. We aimed to further evaluate the efficacy and safety of polaprezinc in 8-week treatment for chronic pressure ulcers. Patients with stage II-IV pressure ulcers for ≥ 8 weeks received 150 mg/day polaprezinc (containing 116 mg L-carnosine and 34 mg zinc) per os for a maximum of 8 weeks. We measured the severity of pressure ulcers weekly using the Pressure Ulcer Scale for Healing (PUSH) score and monitored blood biochemistry. Fourteen patients (nine men; 68.4 ± 11.8 years) were enrolled. Pressure ulcer stages were II (one patient; 7 %), III (nine; 64 %), and IV (four; 29 %). The PUSH score improved significantly from 8.1 [95 % CI, 6.0-10.3] at baseline to -1.4 [-4.0 to 1.1] after 8 weeks (P zinc levels increased significantly (P zinc ratios (P < 0.001) decreased significantly. In one patient, preexisting copper deficiency deteriorated. These preliminary data suggest that polaprezinc may be effective and well-tolerated in 8-week treatment of pressure ulcers and could be a candidate for their oral treatment. PMID:24691900

    Excessive gestational weight gain may lead to long-term increases in maternal body weight and associated health risks. The purpose of this study was to examine the relationship between maternal body weight and weight-related self-efficacy from early pregnancy to 2 years post-partum. Women with live, singleton term infants from a population-based cohort study were included (n = 595). Healthy eating self-efficacy and weight control self-efficacy were assessed prenatally and at 1 year and 2 years post-partum. Body weight was measured at early pregnancy, before delivery, and 6 weeks, 1 year and 2 years post-partum. Behavioural (smoking, breastfeeding) and sociodemographic (age, education, marital status, income) covariates were assessed by medical record review and baseline questionnaires. Multi-level linear regression models were used to examine the longitudinal associations of self-efficacy measures with body weight. Approximately half of the sample (57%) returned to early pregnancy weight at some point by 2 years post-partum, and 9% became overweight or obese at 2 years post-partum. Body weight over time was inversely related to healthy eating (β = -0.57, P = 0.02) and weight control (β = -0.99, P < 0.001) self-efficacy in the model controlling for both self-efficacy measures as well as time and behavioural and sociodemographic covariates. Weight-related self-efficacy may be an important target for interventions to reduce excessive gestational weight gain and post-partum weight gain. PMID:25244078

    2011-09-01

    Full Text Available This experiment was carried out in a 104 m² poultry house located between the geographical coordinates 25°45'00" south latitude and 53°03'25" west longitude and an average altitude of 550 m, from September to November, 2008. The chickens were placed in 12 pens measuring 2 m² each at a stocking density of 12 chickens m-2. This study aimed at evaluating the effect of two different initial weights (chick weight on first day of experiment and two types of litter material on broiler production parameters, litter humidity, as well as on breast and footpad lesions. A total of 240 female Cobb® chickens, derived from the same flock of breeders, was distributed in a completely randomized experimental design with a 2 (initial weight by 2 (litter material factorial arrangement with three replicates per treatment. Initial weights were classified as light (34.40 - 35.22 g or heavy (39.29 - 41.30 g, whereas wood shavings and sawdust were used as litter material. Data were analyzed by ANOVA and means were compared by Tukey's test at 95% confidence level. Initial weight significantly influenced bird performance, as chickens with heavy initial weight presented higher feed intake and body weight. Type of litter did not have any effect on breast injuries and litter humidity. However, the wood shavings litter significantly influenced footpad lesions.

  17. Five-Factor Model Personality Traits and the Objective and Subjective Experience of Body Weight.

    Sutin, Angelina R; Terracciano, Antonio

    2016-02-01

    Research on personality and adiposity has focused primarily on middle-aged and older adults. The present research sought to (a) replicate these associations in a young adult sample, (b) examine whether sex, race, or ethnicity moderate these associations, and (c) test whether personality is associated with the subjective experience of body weight and discrepancies between perceived and actual weight. Participants (N = 15,669; M(age) = 29; 53% female; ∼40% ethnic/racial minority) from Wave 4 of the National Longitudinal Study of Adolescent Health completed a Five-Factor Model personality measure and reported their weight, height, and perception of weight category (e.g., overweight); trained staff measured participants' height, weight, and waist circumference. Conscientiousness was associated with healthier weight, with a nearly 5 kg difference between the top and bottom quartiles. Neuroticism among women and Extraversion among men were associated with higher adiposity. Neuroticism was also associated with misperceived heavier weight, whereas Extraversion was associated with misperceived taller and leaner. The associations were similar across race/ethnic groups. Personality is associated with objective and subjective adiposity in young adulthood. Although modest, the effects are consistent with life span theories of personality, and the misperceptions are consistent with the conceptual worldviews associated with the traits. PMID:25329238

  18. Neighbourhood Influences on Children’s Weight-related Behaviours and Body Mass Index

    Gabrielle L. Jenkin

    2015-08-01

    Full Text Available Introduction: Neighbourhood contextual factors such as accessibility of food shops and green spaces are associated with adult bodyweight but not necessarily weight-related behaviours. Whether these associations are replicated amongst children is unknown.Aim: To understand which aspects of childrens' neighbourhoods are associated with unhealthy weight and weight-related behaviours.Methods: Individual-level data for children from the 2006/7 New Zealand Health Survey (of Body Mass Index (BMI, dietary indicators and socioeconomic variables were linked with geographic level data on neighbourhood deprivation, rural/urban status, percentage of community engaged in active travel, access to green space, food shops and sports/leisure facilities. Logistic regression models were fitted for measures of BMI and weight-related behaviours; sugar sweetened beverage (SSB consumption; fast-food consumption; and television viewing. Results:Increased Ccommunity engagement in active transport was, counterintuitively, the only neighbourhood contextual factor associated with unhealthy weight amongst children. After adjustment for socioeconomic and environmental variables, greater access to green space appeared to have a protective effect on SSB consumption and neighbourhood deprivation was associated with all three unhealthy weight-related behaviours (SSB and fast-food consumption and television viewing. Conclusions: Although further research is needed, evidence from the current study suggests that a repertoire of health promotion interventions and policies to change unhealthy weight- related behaviours in high deprivation neighbourhoods may be required to address childhood obesity.

    Full Text Available David J Browning, Chong Lee, David Rotberg Charlotte Eye, Ear, Nose and Throat Associates, Charlotte, North Carolina, NC, USA Purpose: To determine how algorithms for ideal body weight (IBW affect hydroxychloroquine dosing in women.Methods: This was a retrospective study of 520 patients screened for hydroxychloroquine retinopathy. Charts were reviewed for sex, height, weight, and daily dose. The outcome measures were ranges of IBW across algorithms; rates of potentially toxic dosing; height thresholds below which 400 mg/d dosing is potentially toxic; and rates for which actual body weight (ABW was less than IBW.Results: Women made up 474 (91% of the patients. The IBWs for a height varied from 30–34 pounds (13.6–15.5 kg across algorithms. The threshold heights below which toxic dosing occurred varied from 62–70 inches (157.5–177.8 cm. Different algorithms placed 16%–98% of women in the toxic dosing range. The proportion for whom dosing should have been based on ABW rather than IBW ranged from 5%–31% across algorithms. Conclusion: Although hydroxychloroquine dosing should be based on the lesser of ABW and IBW, there is no consensus about the definition of IBW. The Michaelides algorithm is associated with the most frequent need to adjust dosing; the Metropolitan Life Insurance, large frame, mean value table with the least frequent need. No evidence indicates that one algorithm is superior to others. Keywords: hydroxychloroquine, ideal body weight, actual body weight, toxicity, retinopathy, algorithms

    2015-06-01

    Full Text Available Music is related to stress reduction and increased levels of growth hormone. In rats, music exposure since prenatal period was found to increase body weight of 7-days-old litters and brain cells. Somatic growth was primarily influenced by growth hormone and supported by psycho-physic condition. The objective of this study was to analyze whether music exposure since prenatal until 35 days post-natal period could affect the weight and body-length of the rat-pups. Four pregnant Wistar rats were daily exposed to one hour classic music (Mozart every 17.30 pm since gestation period day one until the 22 litters were 35 days old. Controls were 5 pregnant rats and their 36 litters caged in a different room with no music. Weighing and measuring the body-length (the most anterior point of the nasal septum to the base of the tail were conducted at day 7, 25, and 35. Data were analyzed using Multivariate General-Linear-Modem (α = 0.05. It was revealed that the mean weight of the experimental litters was significantly higher than those of the controls either at day 7 (p = 0.00, day 25 (p = 0.012 or 35 (p = 0.006. Difference of the body-length of the experiment and control animals only significant at day 25 (p = 0.012. Conclusion: Music exposure since prenatal period has significant influences on the weight of the rat-litters aged 7, 25 and 35 days and on the body-length of the 25-days-old litters.

  1. The multidimensional relationship between early adult body weight and women's childbearing experiences.

    Frisco, Michelle L; Weden, Margaret M; Lippert, Adam M; Burnett, Kristin D

    2012-06-01

    This study has three primary goals that make an important contribution to the literature on body weight and childbearing experiences among United States' women. It sheds light on the physiological and social nature of this relationship by examining whether the consequences of early adult weight for lifetime childbearing are shaped by historical social context, women's social characteristics, and their ability to marry. We analyze data from two female cohorts who participated in the National Longitudinal Study of Youth (NLSY79). Cohort 1 entered early adulthood before the U.S. obesity prevalence increased. Cohort 2 entered early adulthood after the obesity prevalence increased. We find that early adult weight is negatively related to the childbearing trajectories and marital status of Cohort 1 but not Cohort 2. Failing to account for race/ethnicity and women's educational background as confounders masks some of these associations, which are evident for both White and Black women. Our results suggest that the health consequences of body weight do not fully drive its impact on childbearing. Rather, the lifetime fertility consequences of early adult weight are malleable, involve social processes, and are dependent on social context. PMID:21944717

  2. The Association between Marital Transitions, Body Mass Index, and Weight: A Review of the Literature

    Lauren Dinour

    2012-01-01

    Full Text Available Objective. To examine the association between different marital transitions and changes in body mass index (BMI and body weight. Methods. A systematic literature search was conducted for peer-reviewed articles published between January 1990 and December 2011. Longitudinal studies were included if they compared dependent variables, such as BMI or weight, before and after a change in marital status. Results. Twenty articles were included: 4 articles described only transitions into marriage and/or cohabitation, 2 articles described only transitions out of marriage and/or cohabitation, and 14 articles described both. Overall, transitions into marriage were associated with weight gain, whereas transitions out of marriage were associated with weight loss. No major differences were observed between genders or across specific marital transition states. Conclusions. Additional research is warranted to better understand this phenomenon and the impact of marital transitions on obesity and obesity-related behaviors. This paper highlights potential opportunities to incorporate programs, practices, and policies that aim to promote and support healthy weights and lifestyles upon entering or leaving a marriage or cohabiting relationship.

    The relationship of body weight (BW) with white adipose tissue (WAT) mass and WAT gene expression pattern was investigated in mice submitted to physical training (PT). Adult male C57BL/6 mice were submitted to two 1.5-h daily swimming sessions (T, N = 18), 5 days/week for 4 weeks or maintained sedentary (S, N = 15). Citrate synthase activity increased significantly in the T group (P < 0.05). S mice had a substantial weight gain compared to T mice (4.06 ± 0.43 vs 0.38 ± 0.28 g, P < 0.01). WAT ...

    Rex rabbit is an important small herbivore for fur and meat production. However, little is known about the gut microbiota in rex rabbit, especially regarding their relationship with different fecal types and growth of the hosts. We characterized the microbiota of both hard and soft feces from rex rabbits with high and low body weight by using the Illumina MiSeq platform targeting the V4 region of the 16S rDNA. High weight rex rabbits possess distinctive microbiota in hard feces, but not in so...

  5. Recombinant human tumor necrosis factor induces acute reductions in food intake and body weight in mice

    1988-01-01

    We examined the effects of treatment with rHuTNF on food consumption and body weight in C3H/HeJ mice. rHuTNF was administered intraperitoneally either by injections of 3, 12, or 24 micrograms twice a day or by implantation of osmotic pumps that released 0.75, 3, or 12 micrograms per day. Dose-dependent reductions in both food intake and weight were induced by rHuTNF. However, in spite of continued exposure to rHuTNF, the mice developed a resistance to rHuTNF and resumed their pretreatment foo...

    Barnard, Neal D; Levin, Susan M; Yokoyama, Yoko

    2015-06-01

    In observational studies, vegetarians generally have lower body weights compared with omnivores. However, weight changes that occur when vegetarian diets are prescribed have not been well quantified. We estimated the effect on body weight when vegetarian diets are prescribed. We searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials for articles through December 31, 2013. Additional articles were identified from reference lists. We included intervention trials in which participants were adults, interventions included vegetarian diets of ≥4 weeks' duration without energy intake limitations, and effects on body weight were reported. Two investigators independently extracted data using predetermined fields. Estimates of body weight change, comparing intervention groups to untreated control groups, were derived using a random effects model to estimate the weighted mean difference. To quantify effects on body weight of baseline weight, sex, age, study duration, study goals, type of diet, and study authorship, additional analyses examined within-group changes for all studies reporting variance data. We identified 15 trials (17 intervention groups), of which 4 included untreated controls. Prescription of vegetarian diets was associated with a mean weight change of -3.4 kg (95% CI -4.4 to -2.4; Pvegetarian diets reduces mean body weight, suggesting potential value for prevention and management of weight-related conditions.

  8. Rapid changes of body weight after a headstand: a metrological analysis.

    Alejandro Acuña-Espinoza

    Full Text Available Despite recent rules from amateur wrestling sport-governing bodies intended to discourage extreme weight loss measures, wrestling culture still includes varied methods to make weight, including holding a headstand position immediately before stepping on the scale. The procedure, according to the notion, will reduce reported mass anywhere between 250 and 500 g (weight between 2.45 and 4.89 N. The aim of this study was to compare any possible differences between the headstand procedure (HS and a normal (CON weight measure, using a metrological approach defined by the European Association of National Metrology Institutes. Seventeen adult men were weighed on a force plate before and after doing a headstand or standing normally for 30s. The order of treatment application was assigned randomly. Post-test weight was significantly larger than pre-test (mean ± s.d. (640.7 ± 62.8 N and 640.3 ± 62.7 N, respectively, p < 0.0001 under both treatments. No treatment vs. time of test interaction was found. No significant difference was found between CON and HS weight (640.6 ± 62.8 N and 640.9 ± 62.9 N, respectively, p=0.3815. The metrological tests suggest that the statistical differences found are related to the force plate measuring errors in every pre-established time interval. The 45 g (0.44 N difference found between pretest and post-test lies within the uncertainty range identified for the equipment (± 110 g or 1.08 N. In conclusion, a 30-second headstand has no significant effect on registered body weight. The small variations obtained were due to equipment-associated measuring errors. This experiment offers systematic empirical evidence to aid in the elimination of this unjustified practice among the wrestling community.

    2013-01-01

    Full Text Available Background. Few safe and effective dietary supplements are available to promote weight loss. We evaluated the safety and efficacy of glucomannan, a water-soluble fiber supplement, for achieving weight loss in overweight and moderately obese individuals consuming self-selected diets. Methods. Participants were randomly assigned to take 1.33 grams of glucomannan or identically looking placebo capsules with 236.6 mL (8 ounces of water one hour before breakfast, lunch, and dinner for 8 weeks. The primary efficacy outcome was change in body weight after 8 weeks. Other efficacy outcomes were changes in body composition, hunger/fullness, and lipid and glucose concentrations. Safety outcomes included gastrointestinal symptoms/tolerance and serum liver enzymes and creatinine levels. Results. A total of 53 participants (18–65 years of age; BMI 25–35 kg/m2 were enrolled and randomized. The two groups did not differ with respect to baseline characteristics and compliance with the study supplement. At 8 weeks, there was no significant difference between the glucomannan and placebo groups in amount of weight loss (−.40±.06 and −.43±.07, resp. or other efficacy outcomes or in any of the safety outcomes. Conclusions. Glucomannan supplements administered over 8 weeks were well tolerated but did not promote weight loss or significantly alter body composition, hunger/fullness, or lipid and glucose parameters. This trial is registered with NCT00613600.

Diffusion-weighted imaging (DWI and diffusion-weighted whole-body imaging with background body signal suppression (DWIBS are useful for this purpose.Patients and methods: One case of ESC with dysphagia presented at our hospital. Endoscopic examination revealed an elevated lesion with an ulcer, and stenosis was detected. DWI showed a high-intensity signal extending from the proximal to the distal ends of the carcinoma and extending to the tunica adventitia. A strong signal was also observed using 18F-fluorodeoxyglucose positron emission tomography (FDG-PET. DWIBS clearly revealed ESC, and these findings, along with those from DWI, suggested that our case had stage-T3 ESC. FDG-PET did not reveal the detailed structure of the ESC. DWIBS, on the other hand, showed that the signal extended to the tunica adventitia and the lumen of the esophagus.Conclusion: These findings suggest that DWI and DWIBS are useful for the detection and assessment of ESC.Keywords: positron emission tomography, endoscopy, computed tomography, cross section, squamous cell carcinoma

    2009-01-01

    The relationship between microsatellite polymorphism and body weight of captive bred Chinese sea cucumber Apostichopus japonicus was investigated in two local populations in Dalian.Among ten loci discovered, nine show changes except for A J07 loci. Seven loci were found highly polymorphic in both populations. For each locus in two populations, the average number of alleles is 6.428 6 and 6.285 7, the average observed heterozygosity at 0.225 7 and 0.245 9, the expected heterozygosity at 0.776 8 and 0.748 8, the polymorphism information content (PIC) at 0.709 2 and 0.674 6, respectively. Further analysis show significant correlation between A. japonicus body weight and occurrence markers AJ02 and AJ04. The findings of the relation may be helpful for molecular breeding,as well as the marker-assisted selection of sea cucumbers.

  15. A dynamical model for describing behavioural interventions for weight loss and body composition change.

    Navarro-Barrientos, J-Emeterio; Rivera, Daniel E; Collins, Linda M

    2011-01-12

    We present a dynamical model incorporating both physiological and psychological factors that predicts changes in body mass and composition during the course of a behavioral intervention for weight loss. The model consists of a three-compartment energy balance integrated with a mechanistic psychological model inspired by the Theory of Planned Behavior (TPB). The latter describes how important variables in a behavioural intervention can influence healthy eating habits and increased physical activity over time. The novelty of the approach lies in representing the behavioural intervention as a dynamical system, and the integration of the psychological and energy balance models. Two simulation scenarios are presented that illustrate how the model can improve the understanding of how changes in intervention components and participant differences affect outcomes. Consequently, the model can be used to inform behavioural scientists in the design of optimised interventions for weight loss and body composition change. PMID:21673826

  16. Reconceptualizing the Association between Food Insufficiency and Body Weight: Distinguishing Hunger from Economic Hardship.

    Ross, Catherine E; Hill, Terrence D

    2013-01-01

    What is the association between food insufficiency and body weight? Although common sense would suggest a negative association, research often finds the opposite. We contrast commodity theories of material privation with stress theories, proposing that the seemingly counterintuitive association results from the confounding influence of economic hardship. Because it is a chronic stressor, economic hardship may contribute to overweight. Data from the WCF project of 2,402 disadvantaged women in Chicago, Boston, and San Antonio show that people who experience economic hardship weigh more; and that the true negative association between body weight and food insufficiency-especially going hungry because one cannot afford food-is revealed only after adjustment for economic hardship.

    2012-05-01

    Maintenance of weight loss remains a challenge for most individuals. Thus, practical and effective weight-loss maintenance (WTLM) strategies are needed. A two-group 12-month WTLM intervention trial was conducted from June 2007 to February 2010 to determine the feasibility and effectiveness of a WTLM intervention for older adults using daily self-monitoring of body weight, step count, fruit/vegetable (F/V) intake, and water consumption. Forty weight-reduced individuals (mean weight lost=6.7±0.6 kg; body mass index [calculated as kg/m²] 29.2±1.1), age 63±1 years, who had previously participated in a 12-week randomized controlled weight-loss intervention trial, were instructed to record daily body weight, step count, and F/V intake (WEV [defined as weight, exercise, and F/V]). Experimental group (WEV+) participants were also instructed to consume 16 fl oz of water before each main meal (ie, three times daily), and to record daily water intake. Outcome measures included weight change, diet/physical activity behaviors, theoretical constructs related to health behaviors, and other clinical measures. Statistical analyses included growth curve analyses and repeated measures analysis of variance. Over 12 months, there was a linear decrease in weight (β=-0.32, Pwater consumption may provide additional WTLM benefits. PMID:22709772

  11. Weight loss and body composition changes following three sequential cycles of ketogenic enteral nutrition

    Gianfranco Cappello

    2012-01-01

    Full Text Available Background: Ketogenic enteral nutrition (KEN is a modification of the protein sparing modified fast in which a protein solution is introduced with a continuous infusion through a nasogastric tube over 10-days cycles. The aim of the study was to perform a retrospective analysis of the safety, compliance, weight loss and body composition changes after 3 sequential 10-days cycles of KEN therapy. Materials and Methods: From a large number of patients who underwent KEN therapy in our department over a 5-year period, we selected 188 patients who participated in 3 KEN cycles with 10-13 days of break between them. Before and after the treatment cycles, body composition was analyzed by bioelectric impedance; a final assessment was made 10 days after the end of last cycle. During each rest period all the patients were on a low-carbohydrate, normal caloric diet. Results: Most patients (97% successfully tolerated the nasogastric treatment and lost an average of 14.4 kg of body weight, 10.6 kg of fat mass and 3.4 kg of body cell mass. Adverse effects were recorded as mild gastric hypersecretion (2% and constipation (5%. Patients continued to lose fat during the 10-day follow up period after the end of each KEN Cycle. This effect may be explained by abnormality of water distribution during the rapid weight loss inducing the observed change in fat mass. Conclusion: Ten-days KEN treatment cycles can induce rapid weight loss and reduction of fat mass in obese patients. Furthermore, preservation of lean mass can be achieved by infusing 1.9 g of protein/kg of BCM.

    Conor Delahunty; Andrew Gray; Alexandra Chisholm; Siew Ling Tey; Rachel Brown

    2011-01-01

    Previous studies have reported that regular nut consumption reduces cardiovascular disease (CVD) risk and does not promote weight gain despite the fact that nuts are energy-dense. However, no studies have investigated the body composition of those regularly consuming nuts compared to similar intakes of other snacks of equal energy density. This parallel study (n = 118) examined the effects of providing daily portions (~1100 kJ/d) of hazelnuts, chocolate, or potato crisps compared to a control...

  13. Does cigarette smoking affect body weight? causal estimates from the clean indoor air law discontinuity

    Pieroni, Luca; Salmasi, Luca

    2012-01-01

    This paper examines the causal effects of smoking behavior on body weight in Italy. In 2005, the Italian government introduced a smoking ban in all indoor public places. We use a regression discontinuity design, which exploits this exogenous variation due to smoking restrictions across cohorts, to achieve identification in our model. Our estimates indicate that the smoking ban reduced cigarette consumption and the smoking participation rate. Most interestingly, we estimate a significant, alth...

  15. The influence of maternal body mass index on fetal weight estimation in twin pregnancy.

    Ryan, Helen M

    2013-11-08

    Sonographic estimation of fetal weight (EFW) is important in the management of high-risk pregnancies. The possibility that increased maternal body mass index (BMI) adversely affects EFW assessments in twin pregnancies is controversial. The aim of this study was to investigate the effect of maternal BMI on the accuracy of EFW assessments in twin gestations prospectively recruited for the ESPRiT (Evaluation of Sonographic Predictors of Restricted growth in Twins) study.

    Metabolic functions are synchronized by the circadian clock setting daily patterns of food intake, nutrient delivery, and behavioral activity. Here, we study the impact of chronic jet-lag (CJL) on metabolism, and test manipulations aimed to overcome potential alterations. We recorded weight gain in C57Bl/6 mice under chronic 6 h advances or delays of the light-dark cycle every 2 days (ChrA and ChrD, respectively). We have previously reported ChrA, but not ChrD, to induce forced desynchronization of locomotor activity rhythms in mice (Casiraghi et al. 2012). Body weight was rapidly increased under ChrA, with animals tripling the mean weight gain observed in controls by day 10, and doubling it by day 30 (6% vs. 2%, and 15% vs. 7%, respectively). Significant increases in retroperitoneal and epidydimal adipose tissue masses (172% and 61%, respectively), adipocytes size (28%), and circulating triglycerides (39%) were also detected. Daily patterns of food and water intake were abolished under ChrA In contrast, ChrD had no effect on body weight. Wheel-running, housing of animals in groups, and restriction of food availability to hours of darkness prevented abnormal increase in body weight under ChrA Our findings suggest that the observed alterations under ChrA may arise either from a direct effect of circadian disruption on metabolism, from desynchronization between feeding and metabolic rhythms, or both. Direction of shifts, timing of feeding episodes, and other reinforcing signals deeply affect the outcome of metabolic function under CJL Such features should be taken into account in further studies of shift working schedules in humans.

    2007-08-01

    Full Text Available The aim of this study was to determine the body weight changes in female patients with bromocriptin treated prolactinoma. Seventeen hyperprolactinemic pre-menopausal female with prolactinoma, aged 18-45 years, with body mass index (BMI 30+/-2,1kg/m2 were included. Basal insulin level was measured in all patients as well as concentrations of luteinizing hormone (LH, follicle-stimulating hormone (FSH, estrogens, testosterone, thyroid-stimulating hormone (TSH and prolactin (PRL. All patients were treated with bromocriptine. PRL levels significantly decreased after six months of the treatment (3543+/-1211 vs.1130+/-588 μIU/ml, p<0.05. After a year of the treatment PRL level was normalized (560+/-297 μIU/ml. Mean body weight did not significantly change during the first 6 months but after a two-year period it significantly decreased (27.6+/-1,4kg/m2. Waist/hip ratio did not significantly change. Normalization of menstrual cycle and libido was obtained in all patients. The results of this study suggest that hyperprolactinemia may be regarded as a reversible cause of obesity in female patients with prolactinoma, and bromocriptin has an important role in the weight loss and insulin decreasing and normalization of gonadotropin secretion as well.

    Ammonia, toxic to aquaculture organisms, represents a potential problem in aquaculture systems, and the situation is exacerbated in closed and intensive shrimp farming operations, expecially for Litopenaeus vannamei. Assessing the potential for the genetic improvement of resistance to ammonia in L. vannamei requires knowledge of the genetic parameters of this trait. The heritability of resistance to ammonia was estimated using two descriptors in the present study: the survival time (ST) and the survival status at half lethal time (SS50) for each individual under high ammonia challenge. The heritability of ST and SS50 were low (0.154 4±0.044 6 and 0.147 5±0.040 0, respectively), but they were both significantly different from zero (P 0.05), suggesting that ST and SS50 could be used as suitable indicators for resistance to ammonia. There were also positive phenotypic and genetic correlation between resistance to ammonia and body weight, which means that resistance to ammonia can be enhanced by the improvement of husbandry practices that increase the body weight. The results from the present study suggest that the selection for higher body weight does not have any negative consequences for resistance to ammonia. In addition to quantitative genetics, tools from molecular genetics can be applied to selective breeding programs to improve the efficiency of selection for traits with low heritability.

    Anorexigenic neuropeptides produced and acting in the brain have the potential to decrease food intake and ameliorate obesity, but are ineffective after peripheral application, owing to a limited ability to cross the blood-brain barrier. We have designed lipidized analogs of prolactin-releasing peptide (PrRP), which is involved in energy balance regulation as demonstrated by obesity phenotypes of both Prrp-knockout and Prrp receptor-knockout mice. The aim of this study was to characterize the subchronic effect of a palmitoylated PrRP analog in two rat models of obesity and diabetes: diet-induced obese Sprague-Dawley rats and leptin receptor-deficient Zucker diabetic (ZDF) rats. In the rats with diet-induced obesity (DIO), a two-week intraperitoneal treatment with palmitoylated PrRP lowered food intake by 24% and body weight by 8%. This treatment also improved glucose tolerance and tended to decrease leptin levels and adipose tissue masses in a dose-dependent manner. In contrast, in ZDF rats, the same treatment with palmitoylated PrRP lowered food intake but did not significantly affect body weight or glucose tolerance, probably in consequence of severe leptin resistance due to a nonfunctional leptin receptor. Our data indicate a good efficacy of lipidized PrRP in DIO rats. Thus, the strong anorexigenic, body weight-reducing, and glucose tolerance-improving effects make palmitoylated PrRP an attractive candidate for anti-obesity treatment. PMID:26906745

  4. Involvement of the Gli3 (Extra-Toes Gene Region in Body Weight in Mice

    Benoît Martin

    2007-01-01

    Full Text Available The mutation extra-toes (Gli3Xt-J on chromosome (Chr 13 of the mouse is known to be involved in the development of the skeleton. The only visible manifestation is the presence of an extra digit on each hind foot. Here we report evidence from several experiments that Gli3XtJ/+ mice weigh more than littermate Gli3+/+ mice, suggesting an effect on body weight of Gli3 or of a gene tightly linked to it on Chr 13. Four independent experiments in different environments were conducted on mice with different genetic backgrounds derived from the C3XtEso Gli3Xt-J/+ Eso/+ linkage testing strain and the JE/Le strain at adult age. The analyses have shown an association between the Gli3Xt-J allele and a body weight increase of about 6.5%. This effect is genetically dominant. It would appear that if the gene of interest is not Gli3 itself, it must be very close to this locus. Indeed, the expected size for this fragment is 7.9 ± 5.3 cM. The manifestation of this gene, observed in two animal facilities and on different genetic backgrounds, is consistent with the idea that the effect of the gene(s is displayed in a stable manner. It accounts for a variation of 6.5% of body weight.

    2014-12-01

    Full Text Available The objective of the present study was to evaluate the supply of a specific-male diet on rooster body weight, hatchability, and fertility. Two diets were supplied during the egg production period: treatment 1, diet formulated for females and containing, in average, 2,830 kcal ME/kg and 15% CP; and treatment 2, diet specifically formulated for male broiler breeders, containing 2,750 kcal ME/kg and 13.5% CP. In the experiment, 26 flocks, with approximately 7,000 females and 840 males each, belonging to the same broiler breeder commercial strain, were distributed into 26 houses (1200m² on the same farm, and submitted to the same management practices. Body weight was evaluated in 13 flocks per treatment and for five weeks (45, 50, 55, 60, 65, and hatchability and fertility in four incubation lots per treatment and for the same weeks. Data were evaluated by the analysis of mixed models for repeated measurements, using the PROC MIXED of SAS 9.3 (SAS Institute Inc., Cary, NC, USA, and means were compared by the test of Tukey-Kramer at 5% significance level. The specific-male diet allowed body weight control during all analyzed weeks and promoted high hatchability and egg fertility. The increase in the number of chicks hatched demonstrates the economic viability of feeding a specific diet for male broiler breeders.

    2005-09-01

    Full Text Available Abstract This study was designed to reveal any differences in effects of fast created versus total inbreeding on reproduction and body weights in mice. A line selected for large litter size for 124 generations (H and a control line (K maintained without selection for the same number of generations were crossed (HK and used as a basis for the experiment. Within the HK cross, full sib, cousin or random mating were practised for two generations in order to create new inbreeding (IBF at a fast rate. In the first generation of systematic mating, old inbreeding was regenerated in addition to creation of new inbreeding from the mating design giving total inbreeding (IBT. The number of pups born alive (NBA and body weights of the animals were then analysed by a model including both IBT and IBF. The IBT of the dam was in the present study found to reduce the mean NBA with -0.48 (± 0.22 (p F was -0.42 (± 0.27. For the trait NBA per female mated, the effect of IBT was estimated to be -0.45 (± 0.29 per 10% increase in the inbreeding coefficient and the effect of IBF was -0.90 (± 0.37 (p F of the dam could be found on sex-ratio and body weights at three and six weeks of age in a population already adjusted for IBT.

    Objective: To explore the characteristics of susceptibility weighted imaging (SWI) of the intravitreous foreign body of autologous eyelashes in rabbits.Methods: A total of 12 New Zealand white rabbits,either sex, weighing 2.5-3.5 kg, and provided by the Experimental Animal Center of Henan Province were employed in this study. For each rabbit, 5 autologous eyelashes (1 cm in length and 0.2-0.3 mm in diameter) were implanted into the right ocular vitreum, while the left control ocular vitreum received sham operation but nothing was implanted. SWI sequential test was made 2 hours postoperatively. Then the rabbits were killed and the specimens of the vitreous bodies of the rabbits were obtained. Hematoxylin and eosin staining and histological examinations were performed. Results: The autologous eyelashes in 8 ocular vitreums of rabbits showed linear low signal intensity on the magnitude images and susceptibility weighted images, but linear high signal intensity on the phase images. Among the 12experimental rabbits, 5 eyelashes in the right vitreum were completely shown in 3 rabbits, partly shown in 5 rabbits (2eyelashes shown in 3 rabbits and 3 eyelashes shown in 2rabbits), and not shown in 4 rabbits. Conclusions: SWI of the foreign body ofintravitreous autologous eyelashes in rabbits has its own characteristics. The combined application of SWI sequential magnitude images, susceptibility weighted images and phase images is helpful to the detection and diagnosis of intravitreous autologous eyelashes in rabbits.

  8. Effect of feeding garlic (allium sativum) on body weight and serum cholesterol levels in rats

    Background: Oral garlic supplementation may be effective in decreasing serum cholesterol levels as much as 15% to 20%. Garlic indirectly effect atherosclerosis by reduction of hyperlipidaemia, hypertension and probably diabetes mellitus and prevents thrombus formation. This study was undertaken to test the hypothesis that garlic powder with a prolonged mode of action promises potent biological effects into hypercholesterolaemia. Methods: Fifty albino rats were randomly divided into 5 equal groups (n=10). All rats were initially fed normal diet for at least 7 days. Then Group A was control and was fed a normal diet + 0.5% cholesterol, Group B was fed normal diet and 3 mg garlic per 10 g of feed and Group C was fed normal diet and 10 mg garlic per 10 g of feed. The experiment lasted for 12 weeks. Body weight and serum cholesterol were noted before and after giving garlic + cholesterol. Results: Effect of serum cholesterol level was significantly decreased after taking 3 and 10 mg of garlic. However it was observed that the body weight was increased after taking garlic. Conclusion: Garlic consumption although can decrease the level of serum cholesterol but it increases the body weight. Garlic consumption alone can decrease serum cholesterol level, but it cannot be used as the main therapeutic agent for hyperlipidaemia. (author)

    Full Text Available Garlic a perennial erect plant is known to have sulphur-containing compounds that act on the hypothalamus increasing the sensitivity of the hypothalamus to leptin which alters the set point at which satiety is reached causing an organism to eat less. Nine mice (six of which were obese were used in this study and grouped into three. Groups A and B were made of 3 obese mice each whereas group C consisted of 3 non-obese mice. For group A and group C mice, 20 ml aqueous garlic extract was added to their feed daily whereas no garlic was added to the feed of group B mice. The study was carried out over a period of 44 days. The weight and blood glucose was measured weekly and the average for each group was computed. Results indicated that Group A mice recorded a reduction in mean body weight by 46.5% (p<0.05. Group B mice had significant increase in mean body weight by 46.2% (p<0.05. The blood glucose level dropped significantly by 18.5% (p<0.05 in group A mice. Garlic had weight loss and hypoglycemic effect in obese mice. These effects were absent in non-obese mice.

    Nan Li

    Full Text Available OBJECTIVE: The aim of the present study was to evaluate the association of maternal prepregnancy body mass index (BMI and gestational weight gain (GWG with anthropometry in the offspring from birth to 12 months old in Tianjin, China. METHODS: Between 2009 and 2011, health care records of 38,539 pregnant women had been collected, and their children had been measured body weight and length at birth, 3, 6, 9 and 12 months of age. The independent and joint associations of pre-pregnancy BMI and GWG based on the Institute of Medicine (IOM guidelines with anthropometry in the offspring were examined using General Linear Model and Logistic Regression. RESULTS: Prepregnancy BMI and maternal GWG were positively associated with Z-scores for birth weight-for-gestational age, birth length-for-gestational age, and birth weight-for-length. Infants born to mothers with excessive GWG had the greatest changes in Z-scores for weight-for-age from birth to Month 3, and from Month 6 to Month 12, and the greatest changes in Z-scores for length-for-age from birth to months 3 and 12 compared with infants born to mothers with adequate GWG. Excessive GWG was associated with an increased risk of offspring overweight or obesity at 12 months old in all BMI categories except underweight. CONCLUSIONS: Maternal prepregnancy overweight/obesity and excessive GWG were associated with greater weight gain and length gain of offspring in early infancy. Excessive GWG was associated with increased infancy overweight and obesity risk.

    2011-09-01

    Full Text Available To establish the relation of body weight indexes and functional state of thyroid in female adolescents with menstrual cycle disorder, living in the iodine-deficiency region, the investigation was conducted in 130 female adolescents with irregular menses. Obesity incidence and overweight in them was 18.5%, body weight deficiency was 43.8%.37.7% of the girls had normal body weight. Statistically significant differences were not defined according to TSH, fT4 and fT3 in patients with different body weight indexes. So, the results of investigation can help to come to the conclusion about the absence of true correlation between body weight and functional thyroid state in female adolescents with irregular menses.

  16. Body Image Distortions, Weight, and Depression in Adolescent Boys: Longitudinal Trajectories into Adulthood.

    Blashill, Aaron J; Wilhelm, Sabine

    2014-01-01

    Depressive symptoms are common among the U.S. population, yet research into prospective risk factors of depression among men is limited. Distorted body image is also prevalent among adolescent boys, and may be linked with elevated depression; however, longitudinal associations have rarely been measured. Thus, the aim of the current study was to assess the prospective relationship between forms of body image distortion and depressive symptoms among adolescent boys, into adulthood. Data were extracted from the National Longitudinal Study of Adolescent Health. Participants were 2,139 U.S. adolescent boys (M age = 16) who were followed prospectively over 13-years (1996 to 2009), into adulthood. Longitudinal mixed-level modeling was employed to assess the temporal prediction of body image distortion on symptoms of depression. Results revealed that boys who were average weight and viewed themselves as either very underweight (very underweight distorted; Cohen's d = .47) or overweight (overweight distorted; Cohen's d = .29) reported significantly higher levels of depressive symptoms compared to boys who accurately viewed their weight as average; this effect remained constant over the 13-year study period. These findings indicated that distortions in body image, particularly extreme distortions, are risk factors for elevated depressive symptoms among adolescent boys, and persist into early adulthood.

  17. The applicability of the dubois height weight formula for measurement of body surface of Indian subjects

    S. S. Ramaswami

    1953-07-01

    Full Text Available The body surface area of 18 healthy adult Indian subjects was measured by taking part by part linear measurements for the whole body with the help of Anthropometry Beam Calipers and applying Du Bois linear formula method. The surface area values computed from Du Bois Height-weight formula were compared with the measured values. The average error in the eighteen cases is 1.5 percent. The standard deviation of the errors is 1.8 percent about the mean error of -0.5 percent. The errors are not statistically significant. As the original Du Bois formula itself is stated to have an average error of 1.5 percent, the present work confirms that the accuracy, with which Du Bois formula predicts body surface, is not sensibly different for Indians as against Europeans

  18. yellow~0,a marker for low body weight in Drosophila melanogaster

    2009-01-01

    Marker-assisted selection(MAS) is an important modern breeding technique,but it has been found that the effect of the markers for quantitative trait loci(QTL) is inconsistent,leading in some cases to MAS failure and raising doubts about its effectiveness.Here the model organism Drosophila melanogaster was employed to study whether an effective marker could be found and applied to MAS.We crossed the stock carrying the y0 marker(a recessive mutation allele of the yellow gene on the X chromosome) with three other stocks carrying corresponding wild-type markers in an F2 design,and found that the y0 marker was in significant association with low body weight(P<0.001).This association was consistent across different backgrounds and the marker effects in female and male were approximately 0.95 σP(phenotypic standard deviation) and 0.68 σP,respectively.We next introgressed a fragment via the y0 marker into a wild stock background over 20 generations of marker-assisted introgression(MAI),and constructed the introgression stock y0(OR)20 in which body weight decreased by 13% and 7%,in female and male,respectively,compared to the wild stock(P<0.0001).This indicated that there must be a single QTL for low body weight that is tightly linked to the y0 marker.We then shortened the introgressed fragment to less than 1.5 cM by a deeper MAI using the y0 marker and the white marker.This narrower fragment also resulted in a similar decrease in body weight to that induced by y0(OR)20,indicating that the QTL for low body weight is located within this less-than-1.5 cM interval.Molecular characteristics of the y0 marker by PCR amplification and Southern blotting revealed that yellow gene was deficient in the y0 stock,leading to disappearance of melanin from the cuticle and probably influencing the developmental process.The above results confirmed the existence of effective QTL markers applicable to MAS breeding schemes,and their potential application in breeding new stocks.

    The aim of this study was to investigate the effects of an 8-week Pilates exercise program on menopausal symptoms and lumbar strength and flexibility in postmenopausal women. In total, 74 postmenopausal women were recruited and randomly allocated to a Pilates exercise group (n=45) and a control group (n=29). Menopausal symptoms were measured through a questionnaire, while lumbar strength was measured through a lumbar extension machine, and lumbar flexibility was measured through sit-and-reach and trunk lift tests performed before and after the Pilates exercise program, respectively. The Pilates exercises consisted of 7-10 min for warm-up, 35-40 min for the main program modified from Pilates Academy International, and 5-7 min for the cool-down, and were performed 3 times a week for 8 weeks. The results showed a significant decrease in menopausal symptoms except urogenital symptoms. Also, the results presented a significant increase in lumbar strength and flexibility after 8 weeks of the Pilates exercise program. We concluded that an 8-week Pilates exercise program is effective in decreasing menopausal symptoms and increasing lumbar strength and flexibility. PMID:27419122

    Full Text Available Abstract Over a period of two years, growth rate and health were measured for dairy calves allowed to suckle their mothers up to 6–8 weeks of age. Thirty-one calves were weighted weekly, and the mean daily growth rate was 1.2 ± 0.03 kg from birth up to 13 weeks of age. Illness in calves and young stock was not observed. In the cows, the mean incidences of ketosis, displaced abomasum, puerperal paresis, mastitis, teat injury and retained placenta were 0, 0, 8, 22, 1 and 1%, respectively, during a 6-year period. The mean daily gain of 56 growing bulls was 1.4 kg when slaughtered at 15 months of age, which is higher than the mean daily gain of 0.95 kg in the population. Probiotics, hormones and vaccines were not used, and antibiotics were only used for treating illness. The present study indicates many advantages and few problems when dairy calves are penned together with the cows and allowed natural feeding up to 6–8 weeks of age. This production system was easy to manage, preferred by the farmer, and may satisfy the public concern regarding the practice of immediate separation of cow and calf in commercial milk production.

    for FFM were strong (r = 0.92 and 0.93). Bland and Altman plots showed limits of agreement of +/-9 kg before and after weight loss; DXA underestimated FFM in women and overestimated FFM in men. DXA accounted for 80% of the lost body weight. The composition of the lost body mass did not differ from...... that estimated by TBK (7.6% FFM and 92.4% FM by TBK; 11% FFM and 89% FM by DXA). CONCLUSION: DXA estimates accurately the body composition and the composition of weight loss in groups of obese subjects. However, the scan table may be too small for patients weighing more than 95 kg....

    Rex rabbit is an important small herbivore for fur and meat production. However, little is known about the gut microbiota in rex rabbit, especially regarding their relationship with different fecal types and growth of the hosts. We characterized the microbiota of both hard and soft feces from rex rabbits with high and low body weight by using the Illumina MiSeq platform targeting the V4 region of the 16S rDNA. High weight rex rabbits possess distinctive microbiota in hard feces, but not in soft feces, from the low weight group. We detected the overrepresentation of several genera such as YS2/Cyanobacteria, and Bacteroidales and underrepresentation of genera such as Anaeroplasma spp. and Clostridiaceae in high weight hard feces. Between fecal types, several bacterial taxa such as Ruminococcaceae, and Akkermansia spp. were enriched in soft feces. PICRUSt analysis revealed that metabolic pathways such as "stilbenoid, diarylheptanoid, gingerol biosynthesis" were enriched in high weight rabbits, and pathways related to "xenobiotics biodegradation" and "various types of N-glycan biosynthesis" were overrepresented in rabbit soft feces. Our study provides foundation to generate hypothesis aiming to test the roles that different bacterial taxa play in the growth and caecotrophy of rex rabbits. PMID:25791609

    Low birth weight and rapid postnatal weight gain are independent and additive risk factors for the subsequent development of metabolic disease. Despite an abundance of evidence for these associations, mechanistic data are lacking. The hormone leptin has received significant interest as a potential programming factor, because differences in the profile of leptin in early life have been associated with altered susceptibility to obesity. Whether leptin alone is a critical factor for programming obesity has, until now, remained unclear. Using the leptin-deficient ob/ob mouse, we show that low birth weight followed by rapid catch-up growth during lactation (recuperated offspring) leads to a persistent increase in body weight in adult life, both in wild-type and ob/ob animals. Furthermore, recuperated offspring are hyperphagic and epididymal fat pad weights are significantly increased, reflecting greater adiposity. These results show definitively that factors other than leptin are crucial in the programming of energy homeostasis in this model and are powerful enough to alter adiposity in a genetically obese strain.

  8. Do body weight and gender shape the work force? The case of Iceland.

    Asgeirsdottir, Tinna Laufey

    2011-03-01

    Most studies of the relationship between body weight - as well as its corollary, beauty - and labor-market outcomes have indicated that it is a function of a gender bias, the negative relationship between excess weight or obesity and labor-market outcomes being greater for women than for men. Iceland offers an exceptional opportunity to examine this hypothesis, given that it scores relatively well on an index of gender equality comprising economic, political, educational, labor-market, and health-based criteria. Equipped with an advanced level of educational attainment, on average, women are well represented in Iceland's labor force. When it comes to women's presence in the political sphere, Iceland is out of the ordinary as well; that Icelanders were the first in the world to elect a woman to be president may suggest a relatively gender-blind assessment in the labor market. In the current study, survey data collected by Gallup Iceland in 2002 are used to examine the relationship between weight and employment within this political and social setting. Point estimates indicate that, despite apparently lesser gender discrimination in Iceland than elsewhere, the bias against excess weight and obesity remains gender-based, showing a slightly negative relationship between weight and the employment rate of women, whereas a slightly positive relationship was found for men.

    OBJECTIVE: To assess birth weight in relation to gestational weight gain (GWG) among women who were and were not obese before pregnancy. METHODS: For a retrospective cohort study, data were obtained for women with a pre-pregnancy body mass index (BMI, calculated as weight in kilograms divided by...... women). RESULTS: A total of 231 obese women were included in analyses. In non-obese and obese women, fetal weight was highest when GWG was above the recommended amount. Among women who had a GWG in line with the recommendations, mean birth weight was higher among those with a pre-pregnancy BMI of 35...... the square of height in meters) of at least 30 who had a singleton delivery at a center in Denmark in 2010-2011. Data were also obtained for 455 non-obese women (BMI 20.0-24.9). GWG was expressed in absolute terms and relative to published recommendations (11-16kg in non-obese women; 5-9kg in obese...

    Defining "healthy weight" is not easy and for an adolescent with all concerns about newly developing physiognomy it is even harder. The aim of this study was to find out the frequency of obesity and the association between the body mass index (BMI), weight-control behaviors and self-perceived body weight status in high school students of a southern city of Turkey. The students from 10 schools were randomly selected among 46,271 students of 72 high schools in Adana from 1999 to 2000. The response rate was 94.8% (2352/2480). The Turkish version of Youth Risk Behavior Survey Questionnaire (YRBSQ) was completed by the students. The students' weights and heights were measured. The mean age was 16.5 +/- 1.0 years of age (range = 14-21 years). The mean BMI was 21.0 +/- 3.1, 25.5% of students were underweight, 65.7% were normal, 6.4% were overweight and 2.3% were obese (p = 0.0001). Of all students, 24.3% defined themselves as thin, 45.3% as normal, 24.9% as overweight and 5.5% as obese (p = 0.0001). The percentage of girls defining their body weight as overweight and obese was significantly higher than the boys (p = 0.0001). Of all students, 35.5% wanted to lose weight, 22.3% wanted to gain weight, 27.8% wanted to keep their current weight. Intention (p = 0.0001) and interventions to lose weight such as going on a diet (p = 0.0001), provocative vomiting (p = 0.0001) and 24-hours starving (p = 0.0001) were significantly higher in girls than boys. Of students, 26.8% (n=620) were on a diet program either to lose or to keep their body weight. There was significant relationship between being on a diet program and intention to change body weight (p = 0.047). We concluded that adolescents living in Adana have relatively higher risk of being underweight than being obese and have unhealthy weight changing plans due to their misperception of their body images. Adolescents may be unconscious on plans and attempts to change their body weights and nutrition and we suggest that

  12. Targeting impulsive processes of eating behavior via the internet. Effects on body weight.

    Veling, Harm; van Koningsbruggen, Guido M; Aarts, Henk; Stroebe, Wolfgang

    2014-07-01

    Because eating behavior can take on an impulsive nature many people experience difficulty with dieting to lose weight. Therefore, an experiment was conducted to test the effectiveness of two interventions targeting impulsive processes of eating behavior to facilitate weight loss: Implementation intentions to remind people about dieting versus a go/no-go task to change impulses toward palatable foods. Dieters performed an online training program (four times in 4 weeks) in which they were randomly assigned to a 2 (implementation intention condition: dieting versus control) × 2 (go/no-go task condition: food versus control) design. They formed either dieting implementation intentions (e.g., If I open the fridge I will think of dieting!) or control implementation intentions. Furthermore, they received either a go/no-go task in which behavioral stop signals were presented upon presentation of palatable foods (food go/no-go task), or upon control stimuli. Participants' weight was measured in the laboratory before and after the intervention. Strength of participants' dieting goal and their Body Mass Index (BMI; as a proxy for impulsiveness toward food) were examined as moderators. Results showed that both dieting implementation intentions and the food go/no-go task facilitated weight loss. Moreover, dieting implementation intentions facilitated weight loss particularly among people with a strong current dieting goal, whereas the food go/no-go task facilitated weight loss independent of this factor. Instead, the food go/no-go task, but not formation of dieting implementation intentions, was primarily effective among dieters with a relatively high BMI. These results provide the first preliminary evidence that interventions aimed at targeting impulsive eating-related processes via the internet can facilitate weight loss. PMID:24675683

  13. The effects of weight loss treatments on upper and lower body fat.

    Kopelman, P G

    1997-08-01

    The intra-abdominal visceral deposition of adipose tissue, which characterises upper body obesity, is a major contributor to the development of hypertension, glucose intolerance and hyperlipidaemia. Conversely, individuals with lower body obesity may have comparable amounts of adipose tissue but remain relatively free from the metabolic consequences of obesity. This raises an obvious question-are there particular weight reducing treatments which specifically target intra-abdominal fat? In theory, surgical removal of upper body fat should be effective. In reality, neither liposuction nor apronectomy ('tummy tuck') have any beneficial metabolic effects, they simply remove subcutaneous adipose tissue which is often rapidly replaced. Vertical banded gastroplasty and gastric bypass operations may be dramatically effective in improving blood pressure, insulin sensitivity and glucose tolerance. However, these benefits result from a parallel reduction in visceral and total body fat. Studies of body fat distribution in postmenopausal women confirm that the marked decrease in adiposity, following a programme of very low calorie diet and exercise, reflects a comparable reduction in visceral and thigh fat. The reduction in waist circumference after a low fat/exercise programme suggests a similar situation in men. Exercise has an important role in treatment but, once again, the fat loss is generalised. Nevertheless, the improved metabolic parameters seen in exercising obese subjects, independent of weight loss, suggest other beneficial actions. Growth hormone (GH) has a marked lipolytic action. GH replacement treatment for GH deficient adults with pronounced abdominal fat deposition, has been shown to reduce intra-abdominal fat by 47% compared to 27% decrease in abdominal subcutaneous fat. Similar beneficial actions on abdominal fat have been reported following treatment with testosterone in obese men. The potential hazards of such treatments make them unsuitable therapy for

    2012-10-01

    Full Text Available Abstract Background Recent studies have shown that body image perception is an important factor in weight control and may be influenced by culture and ethnicity. The aim of the present study was to assess the relationship between immigrant status of the mother and weight status and body image perception of the child. Methods In total, 2706 schoolchildren (1405 boys and 1301 girls aged 8–9 years and their mothers participated in a cross-sectional survey in Emilia-Romagna region (northern Italy. Weight and height of the children were measured and Body Mass Index (BMI was calculated. Actual and ideal body image perception by the children and by the mothers with respect to their children was evaluated according to Collins’ body image silhouettes. Results The BMI values were significantly lower in children of immigrants than in children of Italian mothers (F:17.27 vs 17.99 kg/m2; M:17.77 vs 18.13 kg/m2. The prevalence of overweight/obesity was lower, and the prevalence of underweight higher, in children of immigrant mothers than in those of Italian mothers (overweight- F:21.3 vs 29.1%; M. 28.3 vs 31.4%; underweight- F:5.16 vs 3.84%; M:6.63 vs 2.82%. The children's body image perception was consistent with the differing pattern of nutritional status. In the comparison between actual and ideal figures, the Feel-Ideal Difference Index (FID scores resulted different between the subsample with foreign-born mother in comparison to the native one (significantly lower in daughters of immigrants (FID- F: 0.31 vs 0.57; M: 0.35 vs 0.32. There were significant differences in the choice of the ideal figure of the child between immigrant mothers and Italian mothers (FID- F: -0.05 vs 0.19; M: -0.35 vs −0.03: the ideal figure values were higher in the immigrant mothers of male children and lower in the Italian mothers of female children. Conclusion Our results suggest that cultural and behavioral factors linked to ethnicity play an important role in the

  15. Hemodynamic evaluation of the right portal vein in healthy dogs of different body weights

    de Almeida Mariana F

    2010-05-01

    Full Text Available Abstract Background Doppler ultrasonography is an important tool for evaluating hepatic portal hemodynamics. However, no study in dogs of different body weights, in the range encountered in routine clinical veterinary practice, has been reported. It can be difficult to obtain an ideal insonation angle when evaluating the main portal vein, so evaluation of the right portal vein branch has been described in humans as an alternative. The aim of this study was to analyze, through Doppler ultrasonography, the hemodynamics in the right portal vein branch in dogs of different body weights. Methods Thirty normal dogs were divided in three groups by weight, in order to establish normal values for mean velocity, flow volume and portal congestion index of the right portal vein branch by means of Doppler ultrasonography. Results In all dogs ideal insonation angles were obtained for the right portal vein branch. The average velocity was similar in the three groups, but the portal congestion index and the flow volume differed, showing that the weight of the dog can influence these values. Conclusion Doppler ultrasonography for the evaluation of flow in the right branch of the portal vein could be a viable alternative, or complement, to examining the main vessel segment. This is especially so in those animals in which an ideal insonation angle for examination of the main portal vein is hard to obtain. In addition, the weight of the dog must be considered for the correct evaluation of the portal system hemodynamics, particularly for portal blood flow and the congestion index.

    2012-01-01

    Full Text Available AbstractThe aim of the present study was to investigate the effects of testosterone on certain organs and the macro-anatomical changes induced by this hormone in pubescent male and female rats. The trial was conducted in 32 Sprague-Dawley rats, 16 of which were male and 16 female, at the premises of the Experimental Animals Unit of Selçuk University, Faculty of Veterinary Medicine. The study protocol was approved by the Ethics Board of the same faculty. The male and female rats were allocated to two groups, one which constituted the control group and the other the experimental group. The average body weight of each animal was calculated. The experimental group was injected subcutaneously with 5 mg/kg of testosterone 5 days a week for a period of 10 weeks. At the end of the 10th week, the animals were euthanized; and their average body weight and the weight of the testes, liver, spleen, heart and kidneys were measured. The values of the group, which was administered with testosterone, were compared with those of the control group.The weight of the heart, right kidney, left kidney and spleen of male experimental and control rats did not differ from each other significantly (P>0.05. However, it was determined that testosterone administration led to a statistically significant reduction in the weight of the right and left testes and the liver (p<0.05 in male rats.In result, in the present study, it was demonstrated that testosterone caused certain morphometric changes in the organs of pubescent experimental rats. The results of the present study could be indicative of the effects of testosterone in young athletes, who use anabolic androgenic steroids. The results of the present study may contribute to raising awareness among athletes on the adverse effects of anabolic androgenic steroids.

    Full Text Available Aim To determine an influence of alpha-lipoic acid to reduction of body weight and regulation of total cholesterol concentration, triglycerides and glucose serum levels in obese patients with diabetes mellitus type 2. Methods A prospective study includes two groups of obese patients with diabetes mellitus and signs of peripheral polyneuropathia: examined group (30 patients; 15 females and 15 males, and control group (30 patients; 12 females and 18 males. All were treated with metformin (850-1700 mg/day. Examined patients were additionally treated with alpha-lipoic acid 600 mg/day during 20 weeks. Body mass index and concentrations of total cholesterol, triglycerides and glucose in serum were compared before and after the treatment. Results The group treated with 600 mg alpha-lipoic acid lost significantly more weight, and had lower triglyceride level than the control group. There were no significant differences in total cholesterol and glucose serum levels between the groups. Conclusion Alpha-lipoic acid of 600 mg/day treatment have influenced weight and triglycerides loss in obese patients with diabetes mellitus type 2. It should be considered as an important additive therapy in obese patients with diabetes mellitus type 2.

  19. Anthropometric parameters: weight height, body mass index and mammary volume in relationship with the mammographic pattern

    A prospective study to attempt to relate the anthropometric parameters of height, weight, body mass index as well as age with the mammographic patterns obtained for the patients and obtain an anthropometric profile was carried out. The study was performed in 1.000 women who underwent a mammography in cranial-caudal and medial lateral oblique projection of both breasts, independently of whether they were screened or diagnosed. Prior to the performance of the mammography, weight and height were obtained, and this was also performed by the same technicians, and the patient were asked their bra size to deduce breast volume. With the weight, the body mass index of Quetelet was calculated (weight [kg]/height''2 (ml). After reading the mammography, the patient was assigned to one of the four mammographic patterns considered in the BIRADS (Breast Imaging Reporting and Data System) established by the ACR (American College of Radiology): type I (fat). type II (disperse fibroglandular densities), type III (fibroglandular densities distributed heterogeneously), type 4 (dense). The results were introduced into a computer database and the SPSS 8.0 statistical program was applied, using the statistical model of multivariant logistic regression. In women under 40 years, with normal weight, the dense breast pattern accounted for 67.8% and as the body mass index (BMI) increased, this pattern decreased to 25.1%. The fat pattern is 20% and as the BMI increases, this increased to 80%. In 40-60 year old women with normal weight, the dense pattern accounts for 44% and decreases to 20.9% in the grades II, III and IV obese. The fat pattern is 11.1% and increases to 53.7% in the grade II, III and IV obese. In women over 60 with normal, the dense pattern accounts for 19.3% and and decreases to 13% in the grade III obese. The fat pattern is 5.3% and increases to 20.2% in the grade iii of obesity. As age increases, the probability of presenting a mammographic pattern with a fat image in the

  1. Body weight status, eating behavior, sensitivity to reward/punishment, and gender: relationships and interdependencies

    Anja eDietrich

    2014-10-01

    Full Text Available Behavioral and personality characteristics are factors that may jointly regulate body weight. This study explored the relationship between body mass index (BMI and self-reported behavioral and personality measures. These measures included eating behavior (based on the Three-Factor Eating Questionnaire- TFEQ (Stunkard and Messick, 1985, sensitivity to reward and punishment (based on the BIS/BAS Scales (Carver and White, 1994 and self-reported impulsivity (based on the Barratt Impulsiveness Scale-11 (Patton et al., 1995. We found an inverted U-shaped relationship between restrained eating and BMI. This relationship was moderated by the level of disinhibited eating. Independent of eating behavior, BIS and BAS responsiveness were associated with BMI in a gender-specific manner with negative relationships for men and positive relationships for women. Together, eating behavior and BIS/BAS responsiveness accounted for a substantial proportion of BMI variance (men: ~25%, women: ~32%. A direct relationship between self-reported impulsivity and BMI was not observed. In summary, our results demonstrate a system of linear and non-linear relationships between the investigated factors and BMI. Moreover, body weight status was not only associated with eating behavior (cognitive restraint and disinhibition, but also with personality factors not inherently related to an eating context (BIS/BAS. Importantly, these relationships differ between men and women.

  2. The influence of body weight on social network ties among adolescents.

    Ali, Mir M; Amialchuk, Aliaksandr; Rizzo, John A

    2012-01-01

    Evidence of negative stereotypes, prejudice and discrimination towards obese individuals has been widely documented. However, the effect of a larger body size on social network ties or friendship formations is less well understood. In this paper, we explore the extent to which higher body weight results in social marginalization of adolescents. Using data from a nationally representative sample of adolescents, we estimate endogeneity-corrected models including school-level fixed effects that account for bi-directionality and unobserved confounders to ascertain the effect of body weight on social network ties. We find that obese adolescents have fewer friends and are less socially integrated than their non-obese counterparts. We also find that such penalties in friendship networks are present among whites but not African-Americans or Hispanics, with the largest effect among white females. These results are robust to common environmental influences at the school-level and to controls for preferences, risk attitudes, low self-esteem and objective measures of physical attractiveness.

    AIM: We studied the accuracy of bioelectrical impedance analysis (BIA) to assess changes in body composition during moderate weight loss in obese subjects. METHODS: Estimates of changes in fat mass (FM) and fat-free mass (FFM) by BIA were compared with those by dual-energy X-ray absorptiometry (DXA......) as the reference method during a 10-week standardized weight-loss intervention. In obese women (age: 20-50years, mean BMI: 33.8kg/m(2)) participating in a European multicentre trial (nutrient-gene interactions in human obesity [NUGENOB]), body composition was assessed by BIA (Bodystat QuadScan 4000...... were wide (mean±7-8.5kg). For body-composition changes, although biases were generally non-significant, the limits of agreement were also wide (mean±3.7-4.6kg). An FFM prediction equation for BIA data was developed in subjects scanned with Lunar instruments and cross-validated in an independent sample...

    Full Text Available Strenuous exercise is known to induce oxidative stress leading to the generation of free radicals. The purpose of the present study was to investigate the effects of honey, at a dose (1.5 g/kg weight per d on the MDA and SOD levels of plasma in rats after exhaustive exercise. Male rats (n=48 were divided into four groups, group 1, sedentary with distilled water (Sed -DW n=12, group 2, sedentary control with honey (Sed-H N=12, group 3, exercise trained with distilled water (ET-WD n=12, group 4, exercise trained with honey (ET- H n=12 groups. Four groups were further divided equally into two groups where the rats were studied at rest and immediately after exhaustive exercise. During the training period, groups 2‚4 were treated with 1.5 g/kg body weight honey, freshly diluted by distilled water to 50% and the other groups 1‚3 were treated with distilled water (1 ml just before each administration intragastrically tube daily at 8:00 to rats / once daily for 8 weeks. Endurance training consisted of treadmill running 1.5 h day-1, 5 days a week for 8 weeks, reaching the speed of 2.1 kmh-1at the fourth week. For acute exhaustive exercise, graded treadmill running was conducted reaching the speed of 2.1 km h-1 at the 95th min, 10% uphill, and was continued until exhaustion. Erythrocyte MDA level was significantly increased after exhaustion in groups 1‚3 but not in groups 2‚4 animals compared with the corresponding sedentary rest. Honey treatment caused a significant decrease in MDA levels of groups 2‚ 4 compared to the groups 1‚ 3 animals. While acute exhaustive exercise decreased erythrocyte SOD activity in subgroups 1‚ 3 rats, it increased the activity of this enzyme in groups 2‚ 4 rats. Treadmill training increased the endurance time in trained rats compared with sedentary rats. The results of this study suggest that honey supplementation may be useful to prevent acute exhaustive exercise-induced oxidative stress in erythrocytes by up

    Individuals who are overweight or obese report body image concerns and lower self-esteem. However, little is known about the mechanisms underpinning these associations. The objective of this study was to test body-related shame and guilt as mediators in the association between weight status and self-esteem. Young adult participants (n = 790) completed assessments of self-esteem and body-related guilt and shame, and weight status indicators were measured by trained technicians. Findings from multiple mediation analyses suggest that body-related shame mediates the relationship between weight status and self-esteem. If replicated in longitudinal studies, these findings suggest that reducing body-related emotions may have important implications for improving self-esteem in clinical weight management.

    2012-05-01

    Full Text Available Abstract Background Body weight dissatisfaction is an important factor in preventing weight gain and promoting weight loss or maintenance. This study focuses on differences in the rates of body weight dissatisfaction among obese, preobese and normal weight women and men by socioeconomic status within a general adult population in Germany. Methods Data were analyzed from 4186 adults aged 25 to 74 who participated in a cross-sectional, representative population-based health survey (KORA S4, 1999–2001, Augsburg region/Germany. Body mass was measured anthropometrically and indexed following international standards. Among the 2123 women participating in the survey, 40.3% had a normal weight, 34.9% were preobese, and 24.8% were obese (compared to 25.9%, 51.4% and 22.6% among men, respectively. Body weight dissatisfaction, educational level, household income and occupational status were assessed by computer-aided personal interviewing. An index for socioeconomic status was calculated and categorized into quintiles. Multiple logistic regressions were performed to test for differences in the odds of body weight dissatisfaction across socioeconomic strata in normal weight, preobese and obese groups. Body mass index, age, family status, place of residence and health behaviors were adjusted for. Results Overall, being dissatisfied with one’s body weight was more prevalent in women (48.3% than in men (33.2%. In the normal weight group, no significant differences in the odds of being dissatisfied were found across socioeconomic groups among women or men. Among preobese men, compared to the lowest socioeconomic stratum, increased odds of being dissatisfied with one’s body weight were associated with the highest socioeconomic index group (OR = 2.3, 95% CI: 1.4–3.8, middle and high educational level (OR = 1.6, 95% CI: 1.1–2.3, and OR = 1.9, 95% CI: 1.3–3.7, high income (OR = 1.8, 95% CI: 1.2–2.7, and middle and high occupational

  8. Whole-body vibration training as complement to programs aimed at weight loss

    Carlos Cristi-Montero

    2013-10-01

    Full Text Available Introduction: Whole-body vibration training (WBVT has been shown to be an extremely useful tool for increasing muscle mass, bone tissue, muscle power, flexibility, and strength, among others. However, to date, there are few studies on the effects of WBVT on energy metabolism and whether this tool could be able to enhance weight loss in addition to a nutritional plan and/or exercise. Objective: The aim of this review is to analyse the most recent studies on vibration training in order to determine whether this method constitutes a reliable complement to programs aimed at weight loss. Methods: An updated literature search was conducted using PubMed, SciELO and SPORTDiscus. In addition, a detailed search was also performed from references given in selected studies. Results: WBVT appears to be associated with three pathways involved in weight loss: inhibition of adipogenesis and reduction of fat mass, increased energy expenditure, and increase in muscle mass. After analysing the literature, none of the results for the proposed pathways are consistent, and indeed are often contradictory. Conclusion: Further in-depth research is required on this subject. However, WBVT would appear to be a safe method, and may possibly yield benefits, mainly as regards muscle mass, which in turn might promote weight loss when combined with a nutritional plan and a traditional exercise program.

    Zhang, Cui Hong; Liu, Xiang Yu; Zhan, Yi Wei; Zhang, Long; Huang, Yan Jie; Zhou, Hong

    2015-09-01

    To investigate the single and joint effects of prepregnancy body mass index (BMI) and gestational weight gain (GWG) on pregnancy outcomes, electronic medical records of 14,196 women who delivered singleton live infant at a maternal and child health hospital in Beijing, China, in 2012 were reviewed. Logistic regression was used to assess the associations, adjusting for maternal age, height, education, parity, and offspring sex. Women of high prepregnancy BMI or excessive GWG had higher risks of gestational diabetes mellitus, hypertensive disorders in pregnancy, postpartum hemorrhage, caesarean delivery, macrosomia, and large for gestational age infant, while women of inadequate GWG had higher risks of preterm delivery, low birth weight, and small for gestational age infant. Findings suggest that antenatal care providers should help pregnant women control their GWG to normal. PMID:26058899

    秦涛; 张立勋

    2015-01-01

    Walking is the most basic and essential part of the activities of daily living. To enable the elderly and non-ambulatory gait-impaired patients, the repetitive practice of this task, a novel gait training robot (GTR) was designed followed the end-effector principle, and an active partial body weight support (PBWS) system was introduced to facilitate successful gait training. For successful establishment of a walking gait on the GTR with PBWS, the motion laws of the GTR were planned to enable the phase distribution relationships of the cycle step, and the center of gravity (COG) trajectory of the human body during gait training on the GTR was measured. A coordinated control strategy was proposed based on the impedance control principle. A robotic prototype was developed as a platform for evaluating the design concepts and control strategies. Preliminary gait training with a healthy subject was implemented by the robotic-assisted gait training system and the experimental results are encouraging.

  20. Midupper arm circumference and weight-for-length z scores have different associations with body composition

    Grijalva-Eternod, Carlos S; Wells, Jonathan Ck; Girma, Tsinuel;

    2015-01-01

    understood. OBJECTIVE: We investigated the association between these 2 anthropometric indexes and body composition to help understand why they identify different children as wasted. DESIGN: We analyzed weight, length, MUAC, fat-mass (FM), and fat-free mass (FFM) data from 2470 measurements from 595 healthy...... regression coefficients for the WLZ. Conversely, length showed greater regression coefficients for the MUAC. At all ages, the MUAC was shown to be more influenced than was the WLZ by the FM variability relative to the FFM variability. CONCLUSIONS: The MUAC and WLZ have different associations with body...... composition, and length influences these associations differently. Our results suggest that the WLZ is a good marker of tissue masses independent of length. The MUAC acts more as a composite index of poor growth indexing jointly tissue masses and length.

    2016-07-01

    Full Text Available Background Adolescents’ perception of their weight is a strong factor in shaping dietary habits and weight control and management. Among non-overweight and overweight adolescents, both overestimation and underestimation of weight status are associated with harmful effects. This study aimed to examine the relationship between perceived weight and attitude toward eating disorders among adolescent girls living in Karaj, Iran. Materials and Methods Involving a two-stage random sampling, this cross-sectional study was conducted on a total of 537 high school girls 14-18 years of age living in Karaj. The Eating Attitudes Test (EAT-26 was employed to screen for attitude toward eating disorders. Also, anthropometric measurements (weight and height, perceived and the ideal weights of the participants were assessed.  Results The average age of girls participating in the study was 16.12±1.20. According to the results, 70% of girls had normal body mass index. It was found that the ideal weight of 55% of the girls in the normal body mass index group fell under the lower than normal boundary. Moreover, the prevalence of eating disorders was estimated to be 23.6%. The attitude toward eating disorder was significantly correlated with body mass index of participants and their self-concept (P

  2. Effects of Dietary Calcium on Body Weight, Carcass Fat Content and Adipocyte Size in Male Rats

    J Malekzadeh

    2006-07-01

    Full Text Available Introduction & Objective: Calcium is a micronutrient and now receiving much attention for its doubtful effects on weight and body fatness. A few mechanisms has been suggested for calcium effects on body fatness and the most emphasized one is the reducing of lipolysis and increasing lipogenesis via reducing parathyroid hormone levels. The present study is designed to evaluate the effects of nondairy dietary calcium on adipogenesis and adipocyte size in male Sprague dawley rats. Materials & Methods: This experimental study was done from November to September of 2005 at Tehran school of health, nutrition department. 48 male Spragu-Dawley rats from Damgostar Company were used in three randomly selected groups. The rats were fed low (0.2% W/W, usual (0.5% W/W and high (1.2% W/W dietary calcium based on AIN-93M purified diet. Rats were housed in 12 hours light-dark cycle, 22-25°C room temperature with free access to their respective diets. At the end of the experiment, rats were decapitated and carcass fat content, carcass ash content and mean adipocyte size in testis, peritoneal and subcutaneous fat pads were compared in three groups. The SPSS 11.5 was used as statistical software, running analysis of variance for comparing the effects. Results: weight gain, carcass fat content and adipocyte size, in groups were not significantly different, while serum parathyroid hormone concentrations in high calcium group was significantly lower than low calcium group (p<0.05 and insignificantly lower than usual calcium group [12.36, 23.57 and 42.2 pg/dl respectively]. Serum concentrations of 25-hydroxy cholecalciferol were also insignificantly lower in high calcium group. Conclusion: Our findings suggested that physiological concentration of dietary calcium is not effective on weight gain, body fatness and adipocyte size. Relatively equal fat content beside significant difference in serum parathyroid hormone levels is against the parathyroid theory of calcium

    Full Text Available AIM: To evaluate body composition changes after use of three different types of obesity management protocols: dietary measures and physical activity; acupuncture or laser acupuncture with healthy diet; aiming at achieving stable weight loss among obese Egyptian females. METHODS:  A randomized longitudinal prospective study included 76 obese adult females; aged 26 up to 55 years. Anthropometric, body composition, ultrasonographic and biochemical assessments were done. RESULTS: The three types of obesity management protocols showed significant improvement in body composition (decrease in fat% and increases in FFM and TBW and visceral fat by US. However, nutritional intervention showed highly significant improvement in the skin fold thickness at triceps and biceps sites and peripheral adiposity index.  Acupuncture intervention showed highly significant improvement in fasting blood glucose (decreased and lipid profile (decreased triglycerides, total cholesterol and LDL, and increased HDL. Laser intervention showed highly significant improvement in all the skin fold thickness and some parameters of lipid profile (decreased total cholesterol and LDL. CONCLUSIONS: The three obesity management protocols have significant effect on body composition, but acupuncture has the best effect in improving the lipid profile and fasting blood sugar. In addition, Laser intervention was recommended to improve skin fold thickness and subcutaneous fat.

    2014-11-01

    Full Text Available The objective was to evaluate the frequency of cardiovascular risk factors and hypertension in patients with rheumatoid arthritis depending on body weight. The study involved 100 patients with rheumatoid arthritis and stably selected therapy for more than 6 months at the age from 45 to 65 years (mean age 53,19 ± 5,40 years. Traditional cardiovascular risk was assessed, taking into account risk factors by SCORE scale and amended for patients with RA. The levels of total cholesterol, triglycerides, C-reactive protein, serum creatinine, body mass index, body area index were determined. Arterial hypertension was diagnosed in 41 (41% patients with rheuma¬toid arthritis and was associated with traditional risk factors (age, obesity, rheumatoid factor, hyperuricemia and the duration of glucocorticoid therapy. Obesity and excess body mass occurred in the majority of patients with rheumatoid arthritis, herewith the highest level of inflammation indicators and risk of cardiovascular events was in overweight patients. Obesity was associated with duration of rheumatoid arthritis, the activity of the inflammatory process, the duration of glucocorticoids taking. It is found that the traditional SCORE scale does not fully reflect the risk of cardiovascular events in rheumatoid arthritis. Identification of hypertension and obesity increases the information content of the risk assessment of cardiovascular events in rheumatoid arthritis.

    2013-12-01

    Full Text Available OBJECTIVE: To assess the prevalence of low body weight/thinness, overweight and obesity in a representative sample of children and adolescents from a Brazilian region with low economic development. METHODS: A total of 982 girls and 986 boys, aged seven to 17 years old and assisted by Segundo Tempo Program, from Montes Claros, Minas Gerais, Brazil, were included in the study. Low body weight/thinness, overweight and obesity were defined based on body mass cut-off indexes recommended by the International Obesity Task Force. The prevalence of the nutritional status according to sex and age was compared by chi-square test. RESULTS: In girls, the frequency of low body weight/thinness, overweight and obesity was 4.1, 18.4 and 3.8%, respectively; in boys, these percentages were 6.3, 13.2 and 2.9%, respectively. The low body weight/thinness for girls raised from 2.7% (7-10 years old to 5.5% (15-17 years old; the body weight excess (overweight and obesity decreased from 30.1 to 16.2% for the same age groups. In boys, the corresponding trends were from 3.2 to 9.4% for low body weight/thinness, and from 23.4 to 9.2%, for body weight excess. CONCLUSIONS: The data indicate that, even in a region with low economic status, the body weight excess was the main problem associated with nutritional health. The high overweight and obesity prevalence rates indicate the need of public policies for promoting healthy feeding behaviors and physical activity.

    Mauri Nieminen

    1990-09-01

    Full Text Available Estimation of live weight from measurements of body dimensions is useful in many management activities with domestic animals. In present study live weight was measured from 2932 female and 1037 male semi-domesticated reindeer (Rangifer tarandus tarandus L. during different seasons in 1969-85. The age of reindeer varied between 1 day and 14 yrs. Back length (along back from second spinous process to base of tail and chest girth (just behind front legs were taken also from 1490 female and 510 male reindeer. The growth of reindeer from birth to adulthood was cumulative consisting of a rapid weight accretion during summers followed by a weight loss or stasis during winters. The mathematical analyses of the growth based on exponential solutions gave average values for growth of female and male reindeer. Body weight of females increased until the age of 4.5 yrs and that of males until the age of 5.5 yrs. During winter and spring body weight of hinds decreased 10 to 15 kg and that of stags 30 to 50 kg in different age groups. Significant linear regressions were found between live weight and back length (r = 0.809 and 0.892, live weight and chest girth (r = 0.860 and 0.872 and live weight and combined body measure (back length + chest girth (r = 0.877 and 0.941 and live weight and body volume (r = 0.905 and 0.954, respectively in female and male reindeer. Exponential regressions gave, however, the best estimations of live weight with combined body measure.

    Full Text Available OBJECTIVE: The aim of the present study was to evaluate the single and joint associations of maternal prepregnancy body mass index (BMI and gestational weight gain (GWG with pregnancy outcomes in Tianjin, China. METHODS: Between June 2009 and May 2011, health care records of 33,973 pregnant women were collected and their children were measured for birth weight and birth length. The independent and joint associations of prepregnancy BMI and GWG based on the Institute of Medicine (IOM guidelines with the risks of pregnancy and neonatal outcomes were examined by using Logistic Regression. RESULTS: After adjustment for all confounding factors, maternal prepregnancy BMI was positively associated with risks of gestational diabetes mellitus (GDM, pregnancy-induced hypertension, caesarean delivery, preterm delivery, large-for-gestational age infant (LGA, and macrosomia, and inversely associated with risks of small-for-gestational age infant (SGA and low birth weight. Maternal excessive GWG was associated with increased risks of pregnancy-induced hypertension, caesarean delivery, LGA, and macrosomia, and decreased risks of preterm delivery, SGA, and low birth weight. Maternal inadequate GWG was associated with increased risks of preterm delivery and SGA, and decreased risks of LGA and macrosomia, compared with maternal adequate GWG. Women with both prepregnancy obesity and excessive GWG had 2.2-5.9 folds higher risks of GDM, pregnancy-induced hypertension, caesarean delivery, LGA, and macrosomia compared with women with normal prepregnancy BMI and adequate GWG. CONCLUSIONS: Maternal prepregnancy obesity and excessive GWG were associated with greater risks of pregnancy-induced hypertension, caesarean delivery, and greater infant size at birth. Health care providers should inform women to start the pregnancy with a BMI in the normal weight category and limit their GWG to the range specified for their prepregnancy BMI.

    Full Text Available Abstract Background Associations between body weight, physical activity and dietary intake among a population of metropolitan transit workers are described. Methods Data were collected during October through December, 2005, as part of the baseline measures for a worksite weight gain prevention intervention in four metro transit bus garages. All garage employees were invited to complete behavioral surveys that assessed food choices and physical activity, and weight and height were directly measured. Seventy-eight percent (N = 1092 of all employees participated. Results The prevalence of obesity (BMI >= 30 kg/m2 was 56%. Over half of the transit workers reported consuming fruit (55% and vegetables (59% ≥ 3/week. Reported fast food restaurant frequency was low (13% visited ≥ 3/week. Drivers reported high levels of physical activity (eg. walking 93 minutes/day. However, an objective measure of physical activity measured only 16 minutes moderate/vigorous per day. Compared to other drivers, obese drivers reported significantly less vigorous physical activity, more time sitting, and more time watching television. Healthy eating, physical activity and weight management were perceived to be difficult at the worksite, particularly among obese transit workers, and perceived social support for these behaviors was modest. However, most workers perceived weight management and increased physical activity to be personally important for their health. Conclusion Although transit workers' self-report of fruit and vegetable intake, and physical activity was high, perceived access to physical activity and healthful eating opportunities at the worksite was low. Obese workers were significantly less physically active and were more likely to report work environmental barriers to physical activity.

There was significant correlation between BMI score and monthly personal income.

  19. CALHM1 Deletion in Mice Affects Glossopharyngeal Taste Responses, Food Intake, Body Weight, and Life Span.

    Hellekant, Göran; Schmolling, Jared; Marambaud, Philippe; Rose-Hellekant, Teresa A

    2015-07-01

    Stimulation of Type II taste receptor cells (TRCs) with T1R taste receptors causes sweet or umami taste, whereas T2Rs elicit bitter taste. Type II TRCs contain the calcium channel, calcium homeostasis modulator protein 1 (CALHM1), which releases adenosine triphosphate (ATP) transmitter to taste fibers. We have previously demonstrated with chorda tympani nerve recordings and two-bottle preference (TBP) tests that mice with genetically deleted Calhm1 (knockout [KO]) have severely impaired perception of sweet, bitter, and umami compounds, whereas their sour and salty tasting ability is unaltered. Here, we present data from KO mice of effects on glossopharyngeal (NG) nerve responses, TBP, food intake, body weight, and life span. KO mice have no NG response to sweet and a suppressed response to bitter compared with control (wild-type [WT]) mice. KO mice showed some NG response to umami, suggesting that umami taste involves both CALHM1- and non-CALHM1-modulated signals. NG responses to sour and salty were not significantly different between KO and WT mice. Behavioral data conformed in general with the NG data. Adult KO mice consumed less food, weighed significantly less, and lived almost a year longer than WT mice. Taken together, these data demonstrate that sweet taste majorly influences food intake, body weight, and life span. PMID:25855639

  20. Response to Ascaridia galli infection in growing chickens in relation to their body weight.

    Daş, Gürbüz; Gauly, Matthias

    2014-05-01

    It was hypothesized that chickens with extremely varying body weights (BW) from an otherwise homogeneous host sample cope differently with Ascaridia galli (Schrank 1788) infection. Small and large birds, falling into either the lower or the upper 5% quantiles of BW distribution of a parent stock flock, were selected at an age of 4 weeks, housed separately and fed restrictively with the same amount of feed. At week 5, all the small and large birds (635 and 1,297 g/bird, respectively; P galli eggs and euthanized 52 days post-infection. Small birds had higher daily weight gains (P = 0.004) but final BWs of larger birds were still higher (P galli-specific antibodies and worm length remained unaffected (P > 0.05). In conclusion, large birds resist A. galli infection more effectively than do small ones, possibly through different mechanisms acting on allocation of available nutrient and body reserves under the exposure of the infection.

    2012-01-01

    Full Text Available The present study was aimed at investigating the efficacy and mechanism(s of action of a Chinese herbal formulation, Liuwei Dihuang (LWDH, as a prospective natural weight-lowering product. Following a 2-week acclimation period, 48 obesity-prone (OP-CD rats were divided into 4 groups (n=12 each. One group served as a positive control for obesity (OP, while the other 3 were challenged twice daily by oral gavage with total daily dosages of 500, 1500, or 3500 mg/kg BW LWDH, respectively, for 10 weeks. One group (n=12 of obesity-resistant (OR-CD rats served as the normal control group. All rats were fed the same AIN-93G diet modified to contain 60% energy from fat. The highest LWDH dose significantly reduced body weight during the last 4 weeks of treatment. Food intake was reduced beginning in week 2. The high LWDH dose lowered serum triglyceride (TG and nonesterified fatty acid (NEFA levels and body fat. Both the high and medium doses also lowered serum leptin and insulin levels. Liver function testing revealed no adverse side effects under the current experimental conditions. The results of the present study suggest that LWDH has potential as a preventive or therapeutic natural product against overweight and obesity.

  2. The skinny on cocaine: insights into eating behavior and body weight in cocaine-dependent men.

    Ersche, Karen D; Stochl, Jan; Woodward, Jeremy M; Fletcher, Paul C

    2013-12-01

    There is a general assumption that weight loss associated with cocaine use reflects its appetite suppressing properties. We sought to determine whether this was justified by characterizing, in detail, alterations in dietary food intake and body composition in actively using cocaine-dependent individuals. We conducted a cross-sectional case-control comparison of 65 male volunteers from the local community, half of whom satisfied the DSM-IV-TR criteria for cocaine dependence (n=35) while the other half had no personal or family history of a psychiatric disorder, including substance abuse (n=30). Assessments were made of eating behavior and dietary food intake, estimation of body composition, and measurement of plasma leptin. Although cocaine users reported significantly higher levels of dietary fat and carbohydrates as well as patterns of uncontrolled eating, their fat mass was significantly reduced compared with their non-drug using peers. Levels of leptin were associated with fat mass, and with the duration of stimulant use. Tobacco smoking status or concomitant use of medication did not affect the significance of the results. Weight changes in cocaine users reflect fundamental perturbations in fat regulation. These are likely to be overlooked in clinical practice but may produce significant health problems when cocaine use is discontinued during recovery. PMID:23920064

    Full Text Available Abstract Background An epidemiological study conducted in Italy indicated that coffee has the greatest antioxidant capacity among the commonly consumed beverages. Green coffee bean is rich in chlorogenic acid and its related compounds. The effect of green coffee bean extract (GCBE on fat accumulation and body weight in mice was assessed with the objective of investigating the effect of GCBE on mild obesity. Methods Male ddy mice were fed a standard diet containing GCBE and its principal constituents, namely, caffeine and chlorogenic acid, for 14 days. Further, hepatic triglyceride (TG level was also investigated after consecutive administration (13 days of GCBE and its constituents. To examine the effect of GCBE and its constituents on fat absorption, serum TG changes were evaluated in olive oil-loaded mice. In addition, to investigate the effect on hepatic TG metabolism, carnitine palmitoyltransferase (CPT activity in mice was evaluated after consecutive ingestion (6 days of GCBE and its constituents (caffeine, chlorogenic acid, neochlorogenic acid and feruloylquinic acid mixture. Results It was found that 0.5% and 1% GCBE reduced visceral fat content and body weight. Caffeine and chlorogenic acid showed a tendency to reduce visceral fat and body weight. Oral administration of GCBE (100 and 200 mg/kg· day for 13 days showed a tendency to reduce hepatic TG in mice. In the same model, chlorogenic acid (60 mg/kg· day reduced hepatic TG level. In mice loaded with olive oil (5 mL/kg, GCBE (200 and 400 mg/kg and caffeine (20 and 40 mg/kg reduced serum TG level. GCBE (1%, neochlorogenic acid (0.028% and 0.055% and feruloylquinic acid mixture (0.081% significantly enhanced hepatic CPT activity in mice. However, neither caffeine nor chlorogenic acid alone was found to enhance CPT activity. Conclusion These results suggest that GCBE is possibly effective against weight gain and fat accumulation by inhibition of fat absorption and activation of fat

  4. Systems genetics analysis of body weight and energy metabolism traits in Drosophila melanogaster

    2010-05-01

    Full Text Available Abstract Background Obesity and phenotypic traits associated with this condition exhibit significant heritability in natural populations of most organisms. While a number of genes and genetic pathways have been implicated to play a role in obesity associated traits, the genetic architecture that underlies the natural variation in these traits is largely unknown. Here, we used 40 wild-derived inbred lines of Drosophila melanogaster to quantify genetic variation in body weight, the content of three major metabolites (glycogen, triacylglycerol, and glycerol associated with obesity, and metabolic rate in young flies. We chose these lines because they were previously screened for variation in whole-genome transcript abundance and in several adult life-history traits, including longevity, resistance to starvation stress, chill-coma recovery, mating behavior, and competitive fitness. This enabled us not only to identify candidate genes and transcriptional networks that might explain variation for energy metabolism traits, but also to investigate the genetic interrelationships among energy metabolism, behavioral, and life-history traits that have evolved in natural populations. Results We found significant genetically based variation in all traits. Using a genome-wide association screen for single feature polymorphisms and quantitative trait transcripts, we identified 337, 211, 237, 553, and 152 novel candidate genes associated with body weight, glycogen content, triacylglycerol storage, glycerol levels, and metabolic rate, respectively. Weighted gene co-expression analyses grouped transcripts associated with each trait in significant modules of co-expressed genes and we interpreted these modules in terms of their gene enrichment based on Gene Ontology analysis. Comparison of gene co-expression modules for traits in this study with previously determined modules for life-history traits identified significant modular pleiotropy between glycogen content

  6. Downward spirals of body surveillance and weight/shape concern among African American and Caucasian college women.

    Fitzsimmons, Ellen E; Bardone-Cone, Anna M

    2011-06-01

    Within dominant American culture, females often learn to view themselves from an observer's perspective and to treat themselves as objects to be looked at (i.e., self-objectification), which can result in negative outcomes. Body surveillance (the indicator of self-objectification) has been found to predict concern with weight/shape in predominantly Caucasian samples, but research has not yet examined the potential reciprocal relations between body surveillance and weight/shape concern. Participants were 226 women attending a Midwestern university (70 self-identified as African American and 156 as Caucasian) who provided data at two time points, spaced about 5 months apart. Results revealed that downward spirals of body surveillance and weight/shape concern were apparent for the Caucasian but not the African American women. However, there was evidence that body surveillance helped account for change in weight/shape concern for the African American women. PMID:21596635

  7. Empty plates and larger waists: a cross-sectional study of factors associated with plate clearing habits and body weight.

    Robinson, E; Hardman, C A

    2016-06-01

    Clearing one's plate out of habit when eating may promote excess energy consumption. This study examined whether plate clearing is related to increased body weight in a sample of young adults. It also sought to identify potential determinants of plate clearing. A cross-sectional design was used in which 385 young adults from a UK university completed self-report measures of plate clearing, weight and height, and demographic characteristics. Plate clearing was predictive of heavier body weight in both unadjusted and adjusted analyses. Parental encouragement to clear one's plate during childhood (retrospectively reported) and personal concerns about food waste were both independent predictors of plate clearing tendencies. Clearing one's plate when eating is associated with heavier body weight, and the prevalence of this behaviour may depend on parenting practices and concerns about food waste. Further work examining the longitudinal effect of plate clearing on weight gain is now needed. PMID:26695723

    2008-01-01

    Objective To evaluate the values of whole body diffusion weighted imaging (DWI) in screening primary unknown tumor in patients with metastases.Methods Totally, 34 patients with metastases of primary unknown tumors were scanned with whole body DWI, and conventional magnetic resonance (MR) imaging was performed if suspected lesions were detected. All the metastases including 27 cases of osseous metastases, 2 brain metastases, 2 liver metastases, 1 pulmonary multiple metastasis, 1 neck metastasis and 1 malignant ascites, were diagnosed by computed tomography, single photon emission computed tomography, or MR imaging. For the proven primary tumors diagnosed by biopsy or pathology of surgical specimens, apparent diffusion coefficient (ADC) values of the primary and metastatic lesions were measured respectively. The sensitivity and specificity of this technique for screening primary tumors were evaluated. Results We found 24 cases with suspected primary lesions, in which 23 lesions were proved to be primary tumors, and 1 was proved to be benign lesion. And no definite primary lesion was found in 10 cases on whole body DWI, but in which 1 case was diagnosed with primary tumor by biopsy later, and the other 9 cases remained unknown within follow-up of over half a year. The difference was not significant in ADC values between primary and metastatic lesions (P>0.05). The sensitivity and specificity of whole body DWI for searching primary tumors was 95.8% and 90.0%, respectively. Conclusion Combined with conventional MR scanning, whole body DWI can help to search primary lesions of patients with metastases.

    An intervention study showed that promoting water consumption in schoolchildren prevented overweight, but a mechanism linking water consumption to overweight was not substantiated. We investigated whether increased water consumption replaced sugar-containing beverages and whether changes in water or sugar-containing beverages influenced body weight outcomes. In a secondary analysis of the intervention study in Germany, we analysed combined longitudinal data from the intervention and control groups. Body weight and height were measured and beverage consumption was self-reported by a 24-h recall questionnaire at the beginning and end of the school year 2006/2007. The effect of a change in water consumption on change in sugar-containing beverage (soft drinks and juices) consumption, change in BMI (kg/m2) and prevalence of overweight and obesity at follow-up was analysed using regression analyses. Of 3220 enroled children, 1987 children (mean age 8·3 (sd 0·7) years) from thirty-two schools were analysed. Increased water consumption by 1 glass/d was associated with a reduced consumption of sugar-containing beverages by 0·12 glasses/d (95 % CI -0·16, -0·08) but was not associated with changes in BMI (P=0·63). Increased consumption of sugar-containing beverages by 1 glass/d was associated with an increased BMI by 0·02 (95 % CI 0·00, 0·03) kg/m2 and increased prevalence of obesity (OR 1·22; 95 % CI 1·04, 1·44) but not with overweight (P=0·83). In conclusion, an increase in water consumption can replace sugar-containing beverages. As sugar-containing beverages were associated with weight gain, this replacement might explain the prevention of obesity through the promotion of water consumption. PMID:27040694

    2006-03-01

    Full Text Available The Brazilian Swine and Poultry Research Center (Embrapa Suínos e Aves maintains a chicken breeding program for meat production since 1985. Two control lines (LLc and PPc are maintained, whereas two male lines (TT and ZZ and three female lines (PP, VV and KK have been selected. This paper reports the genetic gain after 15 generations of combined selection (mass and independent culling levels in order to develop the commercial broiler stocks Embrapa 021 and Embrapa 022. Selection pressure has been exerted on weight gain, carcass traits and fertility. In addition, female lines have also been selected for egg production, whereas males have been selected for feed efficiency since 1992. All lines have been selected for breast area instead of carcass traits since 1999. The genetic gain was estimated as the deviation between selected lines and the respective unselected lines at 42 days of age. In female lines, body weight improved 504, 548 and 587 g; average breast area increased 27.60; 16.99 and 26.43 cm²; adjusted feed conversion (42-49 d improved -1.46; -0.97 and 1.76 units, and egg production varied 6.99; 7.12 and -3.43% units for PP, VV and KK, respectively. In male lines, body weight improved 758 and 408 g; average breast area increased 31.95 and 19.38 cm², and adjusted feed conversion improved (42-49 d -0.99 and 1.26 for TT and ZZ, respectively. This breeding program has been effective to generate genetic gain and to develop two commercial products, Embrapa 021 (standard and Embrapa 022 (high yield. Nevertheless, feed efficiency is still not satisfactory.

    Jacquier, Marine; Crauste, Fabien; Soulage, Christophe O.; Soula, Hédi A

    2014-01-01

    Dynamics of body weight and food intake can be studied by temporally perturbing food availability. This perturbation can be obtained by modifying the amount of available food over time while keeping the overall food quantity constant. To describe food intake dynamics, we developed a mathematical model that describes body weight, fat mass, fat-free mass, energy expenditure and food intake dynamics in rats. In addition, the model considers regulation of food intake by leptin, ghrelin and glucos...

  13. Feeding Period Restriction Alters the Expression of Peripheral Circadian Rhythm Genes without Changing Body Weight in Mice

    2012-01-01

    Accumulating evidence suggests that the circadian clock is closely associated with metabolic regulation. However, whether an impaired circadian clock is a direct cause of metabolic dysregulation such as body weight gain is not clearly understood. In this study, we demonstrate that body weight gain in mice is not significantly changed by restricting feeding period to daytime or nighttime. The expression of peripheral circadian clock genes was altered by feeding period restriction, while the ex...

    2015-08-01

    Full Text Available Background: Obesity is widely recognized as one of the most critical health threats to families and children across the country. Obesity is a very serious health problem for people in Louisiana and especially in African Americans Children with 40.5% in the State classified as either overweight or obese as compared to 41.2% nationally. African American women have the highest rates of being overweight or obese (79.8% compared to non-Hispanic whites (57.9%. In 2007, African Americans were 1.4 times as likely to be obese as whites. Therefore this study was designed to test the impact of dietary whey protein (WP and resistant starch (RS shakes/smoothies on reduction of body fat via increased satiety and increased energy expenditure in African Americans. Methods: Twenty eight African American males and females, age 21-43 years old were randomly divided into two groups. For a period of 24-weeks, the treatment group consumed WP and RS shakes/smoothies for breakfast and received nutrition education. For the same period, the control group consumed the same shake/smoothies but with starch powder and received nutrition education. The data was analyzed using SAS version 9.3. Results: At the end of the 24 week study, the treatment group lost a mean body weight of approximately 7 kg (P ≤ 0.008 that was significantly different from the control group (P ≤ 0.209. In addition, the treatment group exhibited a significant decrease of ~6 cm in waist circumference (P ≤ 0.023. There was no significant effect on mean blood pressure in treatment and control group. Conclusion: The findings from this study suggest that a combination of WP and RS in the form of shake/smoothie consumed for breakfast along with a nutrition education component may be an effective method in decreasing body weight, improving waist circumferences and cumulative food intake in African American males and females.

  16. Lifestyle interventions targeting changes in body weight and composition among youth with an intellectual disability: A systematic review.

    Maïano, Christophe; Normand, Claude L; Aimé, Annie; Bégarie, Jérôme

    2014-08-01

    Over the past three decades, the potential effects of lifestyle interventions targeting changes in body weight and composition (weight, body mass index, fat mass, waist circumference) among adults with an intellectual disability (ID) have been examined in various systematic reviews. Nevertheless, since the middle of the 1980s, the potential effects of these interventions for youth with an ID remain an open question. The purpose of this article is to review the effects of lifestyle interventions targeting changes in body weight and composition among youth with an ID. This review will focus on changes in body weight and composition, healthy lifestyle, and secondary health conditions. A systematic review of English- and French-language studies, published between 1981 and 2013, was performed on Academic Search Complete, PsycARTICLES, Medline and Scopus. The nine studies included in this review focused mainly on: a sample with a wide age range (e.g., 7-22 years); males; overweight-obese youth having a mild-to-moderate ID with Down or Prader-Willi syndrome; physical activity interventions; cohort pre- and post-test designs with/without a control group; and changes in body weight and composition. Taken together, results from these studies suggest successful changes in weight, body mass index and fat mass. However, intervention effects on healthy lifestyle and secondary health conditions are scarce and inconclusive. Given the weaknesses of the reviewed studies, the present findings should be considered preliminary and indicative of the need for future research. PMID:24830882

  17. Lifestyle patterns associated with diet, physical activity, body mass index and amount of recent weight loss in a sample of successful weight losers

    Fuglestad Paul T

    2012-06-01

    Full Text Available Abstract Background Research suggests that the interaction between biological susceptibility and environmental risk is complex and that further study of behavioral typologies related to obesity and associated behaviors is important to further elucidate the nature of obesity risk and how to approach it for intervention. The current investigation aims to identify phenotypical lifestyle patterns that might begin to unify our understanding of obesity and obesity related behaviors. Methods Individuals who had recently lost substantial weight of their own initiative completed measures of intentional weight control behaviors and lifestyle behaviors associated with eating. These behaviors were factor analyzed and the resulting factors were examined in relation to BMI, recent weight loss, diet, and physical activity. Results Four meaningful lifestyle and weight control behavioral factors were identified— regularity of meals, TV related viewing and eating, intentional strategies for weight control, and eating away from home. Greater meal regularity was associated with greater recent weight loss and greater fruit and vegetable intake. Greater TV related viewing and eating was associated with greater BMI and greater fat and sugar intake. More eating away from home was related to greater fat and sugar intake, lower fruit and vegetable intake, and less physical activity. Greater use of weight control strategies was most consistently related to better weight, diet, and physical activity outcomes. Conclusions Compared to the individual behavior variables, the identified lifestyle patterns appeared to be more reliably related to diet, physical activity, and weight (both BMI and recent weight loss. These findings add to the growing body of literature identifying behavioral patterns related to obesity and the overall weight control strategy of eating less and exercising more. In future research it will be important to replicate these behavioral factors (over

    Combination therapy is being increasingly used as a treatment paradigm for metabolic diseases such as diabetes and obesity. In the peptide therapeutics realm, recent work has highlighted the therapeutic potential of chimeric peptides that act on two distinct receptors, thereby harnessing parallel complementary mechanisms to induce additive or synergistic benefit compared to monotherapy. Here, we extend this hypothesis by linking a known anti-diabetic peptide with an anti-obesity peptide into a novel peptide hybrid, which we termed a phybrid. We report on the synthesis and biological activity of two such phybrids (AC164204 and AC164209), comprised of a glucagon-like peptide-1 receptor (GLP1-R) agonist, and exenatide analog, AC3082, covalently linked to a second generation amylin analog, davalintide. Both molecules acted as full agonists at their cognate receptors in vitro, albeit with reduced potency at the calcitonin receptor indicating slightly perturbed amylin agonism. In obese diabetic Lep(ob)/Lep (ob) mice sustained infusion of AC164204 and AC164209 reduced glucose and glycated haemoglobin (HbA1c) equivalently but induced greater weight loss relative to exenatide administration alone. Weight loss was similar to that induced by combined administration of exenatide and davalintide. In diet-induced obese rats, both phybrids dose-dependently reduced food intake and body weight to a greater extent than exenatide or davalintide alone, and equal to co-infusion of exenatide and davalintide. Phybrid-mediated and exenatide + davalintide-mediated weight loss was associated with reduced adiposity and preservation of lean mass. These data are the first to provide in vivo proof-of-concept for multi-pathway targeting in metabolic disease via a peptide hybrid, demonstrating that this approach is as effective as co-administration of individual peptides.

    Context: Maternal obesity and gestational diabetes mellitus (GDM) can both contribute to adverse neonatal outcomes. The extent to which this may be mediated by differences in placental metabolism and nutrient transport remains to be determined. Objective: Our objective was to examine whether raised maternal body mass index (BMI) and/or GDM contributed to a resetting of the expression of genes within the placenta that are involved in energy sensing, oxidative stress, inflammation, and metabolic pathways. Methods: Pregnant women from Spain were recruited as part of the “Study of Maternal Nutrition and Genetics on the Foetal Adiposity Programming” survey at the first antenatal visit (12–20 weeks of gestation) and stratified according to prepregnancy BMI and the incidence of GDM. At delivery, placenta and cord blood were sampled and newborn anthropometry measured. Results: Obese women with GDM had higher estimated fetal weight at 34 gestational weeks and a greater risk of preterm deliveries and cesarean section. Birth weight was unaffected by BMI or GDM; however, women who were obese with normal glucose tolerance had increased placental weight and higher plasma glucose and leptin at term. Gene expression for markers of placental energy sensing and oxidative stress, were primarily affected by maternal obesity as mTOR was reduced, whereas SIRT-1 and UCP2 were both upregulated. In placenta from obese women with GDM, gene expression for AMPK was also reduced, whereas the downstream regulator of mTOR, p70S6KB1 was raised. Conclusions: Placental gene expression is sensitive to both maternal obesity and GDM which both impact on energy sensing and could modulate the effect of either raised maternal BMI or GDM on birth weight.

    Full Text Available Background Being overweight is a characteristic that may influence a person’s heat exchange. Objectives The purpose of this study was to assess the effect of body weight on heat strain indices in hot and dry climatic conditions. Materials and Methods This study was completed with a sample of 30 participants with normal weights, as well as 25 participants who were overweight. The participants were physically inactive for a period of 120 minutes in a climatic chamber with hot and dry conditions (22 - 32°C and with 40% relative humidity (RH.The physiological strain index (PSI and heat strain score index (HSSI questionnaires were used. Simultaneous measurements were completed during heat exposure for periods of five minutes. The resting periods acted as the initial measurements for 15 minutes. Results In both groups, oral temperature, heart rate, and thermal perceptual responses increased during heat exposure. The means and standard deviations of heart rate and oral temperature were gathered when participants were in hot and dry climatic conditions and were not physically active. The heart rates and oral temperatures were 79.21 ± 5.93 bpm and 36.70 ± 0.45°C, respectively, for those with normal weights. For overweight individuals, the measurements for heart rate and oral temperature reached 82.21 ± 8.9 bpm and 37.84 ± 0.37°C, respectively. Conclusions The results showed that, compared to participants with normal weights, physiological and thermal perceptual responses were higher in overweight participants. Therefore, overweight individuals should avoid hot/dry weather conditions to decrease the amount of heat strain.

    Evidence is conflicting as to whether youth obesity prevalence has reached a plateau in the United States overall. Trends vary by state, and experts recommend exploring whether trends in weight-related behaviors are associated with changes in weight status trends. Thus, our objective was to estimate between-state variation in time trends of adolescent body mass index (BMI) percentile and weight-related behaviors from 2001 to 2007. A time series design combined cross-sectional Youth Risk Behav...

  5. Atherosclerosis and cardiac function assessment in low-density lipoprotein receptor-deficient mice undergoing body weight cycling

    McMillen, T S; Minami, E.; LeBoeuf, R C

    2013-01-01

    Background: Obesity has become an epidemic in many countries and is supporting a billion dollar industry involved in promoting weight loss through diet, exercise and surgical procedures. Because of difficulties in maintaining body weight reduction, a pattern of weight cycling often occurs (so called ‘yo-yo' dieting) that may result in deleterious outcomes to health. There is controversy about cardiovascular benefits of yo-yo dieting, and an animal model is needed to better understand the cont...

    Chlorpyrifos is one of the largest used and saled organophosphorus pesticides throughout the world. To explore the testicular oxidative damage of 8 week offspring male rat induced by perinatal exposure to chlorpyrifos, the healthy pregnant Wistar female rats were exposed to chlorpyrifos of 0, 0.75, 1.35 and 2.70 mg•kg-1 by gavage during GD 6—PND21 d. Until the offspring male rat reached the age of 8 week, histopathological changes of left testis were observed. We also detected the level of MDA and the activity of GST, GSH-Px, and T-SOD in right tes-tis. The results showed that although no statistical significance were observed in body weight, the organ coefficient of testis and epididymis compared with control group, both of them showed a downward trend and of MDA showed an upward trend when the dose increased (P>0.05). The decrease in the activity of T-SOD of all dose groups, the increase of the activity of GSH-Px of 1.35 mg•kg-1 and 2.70 mg•kg-1 dose groups and the increase in activity of GST of 2.70 mg•kg-1 dose group were statistically significant (P0.05);而MDA呈升高趋势(P>0.05)。各组T-SOD和1.35、2.70 mg•kg-1剂量组GSH-Px活力的下降及2.70 mg•kg-1剂量组GST活力的升高均有统计学意义(P<0.05)。睾丸组织病理学检查结果可见2.70 mg•kg-1剂量组睾丸组织有明显的损伤,管腔中精液量减少,生精细胞脱落增多。上述研究结果提示母鼠于围生期暴露于毒死蜱,可通过氧化损伤诱导子代雄性大鼠睾丸的毒性作用。

  7. Green tea polyphenols reduce body weight in rats by modulating obesity-related genes.

    Chuanwen Lu

    Full Text Available Beneficial effects of green tea polyphenols (GTP against obesity have been reported, however, the mechanism of this protection is not clear. Therefore, the objective of this study was to identify GTP-targeted genes in obesity using the high-fat-diet-induced obese rat model. A total of three groups (n = 12/group of Sprague Dawley (SD female rats were tested, including the control group (rats fed with low-fat diet, the HF group (rats fed with high-fat diet, and the HF+GTP group (rats fed with high-fat diet and GTP in drinking water. The HF group increased body weight as compared to the control group. Supplementation of GTP in the drinking water in the HF+GTP group reduced body weight as compared to the HF group. RNA from liver samples was extracted for gene expression analysis. A total of eighty-four genes related to obesity were analyzed using PCR array. Compared to the rats in the control group, the rats in the HF group had the expression levels of 12 genes with significant changes, including 3 orexigenic genes (Agrp, Ghrl, and Nr3c1; 7 anorectic genes (Apoa4, Cntf, Ghr, IL-1β, Ins1, Lepr, and Sort; and 2 genes that relate to energy expenditure (Adcyap1r1 and Adrb1. Intriguingly, the HF+GTP group restored the expression levels of these genes in the high-fat-induced obese rats. The protein expression levels of IL-1β and IL-6 in the serum samples from the control, HF, and HF+GTP groups confirmed the results of gene expression. Furthermore, the protein expression levels of superoxide dismutase-1 (SOD1 and catechol-O-methyltransferase (COMT also showed GTP-regulated protective changes in this obese rat model. Collectively, this study revealed the beneficial effects of GTP on body weight via regulating obesity-related genes, anti-inflammation, anti-oxidant capacity, and estrogen-related actions in high-fat-induced obese rats.

  9. Reciprocal effects among changes in weight, body image, and other psychological factors during behavioral obesity treatment: a mediation analysis

    Barata José T

    2009-02-01

    Full Text Available Abstract Background Changes in body image and subjective well-being variables (e.g. self-esteem are often reported as outcomes of obesity treatment. However, they may, in turn, also influence behavioral adherence and success in weight loss. The present study examined associations among obesity treatment-related variables, i.e., change in weight, quality of life, body image, and subjective well-being, exploring their role as both mediators and outcomes, during a behavioral obesity treatment. Methods Participants (BMI = 31.1 ± 4.1 kg/m2; age = 38.4 ± 6.7 y were 144 women who attended a 12-month obesity treatment program and a comparison group (n = 49, who received a general health education program. The intervention included regular group meetings promoting lasting behavior changes in physical activity and dietary intake. Body image, quality of life, subjective well-being, and body weight were measured at baseline and treatment's end. Mediation was tested by multiple regression and a resampling approach to measure indirect effects. Treatment group assignment was the independent variable while changes in weight and in psychosocial variables were analyzed alternatively as mediators and as dependent variables. Results At 12 months, the intervention group had greater weight loss (-5.6 ± 6.8% vs. -1.2 ± 4.6%, p Conclusion Changes in weight and body image may reciprocally affect each other during the course of behavioral obesity treatment. No evidence of reciprocal relationships was found for the other models under analysis; however, weight changes partially explained the effects of treatment on quality of life and self-esteem. Weight and psychosocial changes co-occur during treatment and will probably influence each other dynamically, in ways not yet adequately understood. Results from this study support the inclusion of intervention contents aimed at improving body image in weight management programs.

  10. Does the method of weight loss effect long-term changes in weight, body composition or chronic disease risk factors in overweight or obese adults? A systematic review.

    Richard A Washburn

    Full Text Available BACKGROUND: Differences in biological changes from weight loss by energy restriction and/or exercise may be associated with differences in long-term weight loss/regain. OBJECTIVE: To assess the effect of weight loss method on long-term changes in weight, body composition and chronic disease risk factors. DATA SOURCES: PubMed and Embase were searched (January 1990-October 2013 for studies with data on the effect of energy restriction, exercise (aerobic and resistance on long-term weight loss. Twenty articles were included in this review. STUDY ELIGIBILITY CRITERIA: Primary source, peer reviewed randomized trials published in English with an active weight loss period of >6 months, or active weight loss with a follow-up period of any duration, conducted in overweight or obese adults were included. STUDY APPRAISAL AND SYNTHESIS METHODS: Considerable heterogeneity across trials existed for important study parameters, therefore a meta-analysis was considered inappropriate. Results were synthesized and grouped by comparisons (e.g. diet vs. aerobic exercise, diet vs. diet + aerobic exercise etc. and study design (long-term or weight loss/follow-up. RESULTS: Forty percent of trials reported significantly greater long-term weight loss with diet compared with aerobic exercise, while results for differences in weight regain were inconclusive. Diet+aerobic exercise resulted in significantly greater weight loss than diet alone in 50% of trials. However, weight regain (∼ 55% of loss was similar in diet and diet+aerobic exercise groups. Fat-free mass tended to be preserved when interventions included exercise.

  11. In it together: Mother talk of weight concerns moderates negative outcomes of encouragement to lose weight on daughter body dissatisfaction and disordered eating.

    Hillard, Erin E; Gondoli, Dawn M; Corning, Alexandra F; Morrissey, Rebecca A

    2016-03-01

    Mothers' influence on their daughters is important for understanding girls' disordered eating and body dissatisfaction. Direct maternal encouragement of daughters to lose weight is linked to daughters' development of bulimic symptoms, and additional findings indicate that daughters whose mothers merely talk about dieting and body dissatisfaction are more likely to be diagnosed with an eating disorder. The current study extends such research by examining the interactive contributions of maternal encouragement to lose weight and maternal dieting discussions to the prediction of early adolescent daughters' body dissatisfaction and disordered eating over the middle school period. Participants were 89 adolescent girls who were in the 6th grade at Time 1. Regression analyses were conducted to examine interactive effects of mother encouragement to diet and talk of weight concerns on daughter body dissatisfaction, drive for thinness, and dieting behavior. Results suggest an interactive effect in which mothers' dieting talk may act as a buffer against the negative effects of direct encouragement to lose weight. PMID:26551484

    The purpose of this study was to investigate the influence of apple pomace (AP) and apple juice concentrate (AC) supplementation on body weight and fat loss as well as lipid metabolism in obese rats fed a high-fat diet. Diet-induced obese rats were assigned to three groups (n=8 for each group): high fat diet (HFD) control, HFD containing 10% (w/w) AP, and HFD containing 10% (w/w) AC. There was also a normal diet group (n=8). After 5 weeks, body weight gain, adipose tissue weight, serum and he...

  13. The Effect of Body Weight Support on Kinetics and Kinematics of a Repetitive Plyometric Task.

    Elias, Audrey R; Hammill, Curt D; Mizner, Ryan L

    2016-02-01

    Though essential to athletic performance, the ability to land from a jump often remains limited following injury. While recommended, jump training is difficult to include in rehabilitation programs due to high impact forces. Body weight support (BWS) is frequently used in rehabilitation of gait following neurological and orthopedic injury, and may also allow improved rehabilitation of high-impact tasks. There is a differential effect of BWS on walking and running gaits, and the effect of BWS on movements with relatively large vertical displacement is unknown. The current study evaluates the effect of BWS on a replicable single-leg hopping task. We posited that progressive BWS would decrease limb loading while maintaining the joint kinematics of the task. Twenty-eight participants repetitively hopped on and off a box at each of four BWS levels. Peak vertical ground reaction forces decreased by 22.5% between 0% and 30% BWS (P rehabilitation of jumping tasks. PMID:26398961

    2013-10-15

    The clinical implementation of whole body diffusion weighted imaging (WB-DWI) for tumor-detection, -characterization and therapy monitoring is well underway. The method is fast, robust and combined with its wide availability on modern MRI scanners, it has a vast potential clinical impact. Owing to the high tumor to background contrast, its main application areas are simple detection of tumor suspicious lesions (primary tumor, recurrence, and metastasis), tumor grading and therapy monitoring. WB-DWI has a strong diagnostic potential regarding the evaluation of bone marrow and its diseases and as thus, tumor detection and therapy monitoring of bone metastasis is of particular interest. The assessment of a lymphatic tumor spreading is constricted. One of the major hurdles that still hamper the wide clinical application of WB-DWI is a lack of standardization of measurement parameters that limit the comparability of current research results.

  15. Education for healthy body weight: helping adolescents balance the cultural pressure for thinness.

    Collins, M E

    1988-08-01

    Though education for healthy body weight traditionally has focused on obesity, the increased incidence of anorexia nervosa and bulimia among young women suggests education also is needed to address the opposite end of the spectrum. Anorexia nervosa and bulimia are complex and multidimensional disorders associated with individual, family, and sociocultural factors. This article examines the cultural pressure for dieting and thinness currently experienced in America and its impact as a possible predisposing factor for developing eating disorders among adolescent females. Literature is reviewed related to the changing American standard of attractiveness for females reflected by 20th century mass media and its subsequent influence on adolescent concerns for dieting and thinness. Preventive strategies are recommended to help adolescents balance the cultural pressure for thinness and their own desires for attractiveness within the larger context of overall good health.

    Vibrio alginolyticus is a virulent pathogen that affects crab aquacultures. In the present study, the immune responses and antioxidant status of big and small (based on body weight and size) 80-, 100- and 120-day-old specimens of Portunus trituberculatus, challenged for 72 h with Vibrio alginolyticus, were studied. The total hemocyte count (THC), and phagocytic, prophenoloxidase and phenoloxidase activities, of the big individuals (BIs) were higher than those of the small individuals (SIs) (P hemolymph and hepatopancreases of the BIs were higher than in the SIs (P hemolymph, or glutathione peroxidase activity in the cell-free hemolymph or hepatopancreas between the BIs and SIs. The α2-M and crustin gene expression levels in the hemocytes, and SOD expression in the hemocytes and hepatopancreas, were also significantly higher in the BIs. The results suggest that, compared with the SIs, the BIs possessed a higher resistance to V. alginolyticus infection. PMID:26952172

    Zheng-yu Jin; Hua-dan Xue; Hua Tao

    2008-01-01

    @@ Cancer has become the leading cause of mortality in the urban area of China. Whole body diffusion weighted imaging (WB-DWI), also known as virtual positron emission tomography, has gradually become accepted as an image tool in tumor localization, characterization, staging and monitoring response to therapy or tumor recurrence. Our article aimed to summarize the limited initial clinical use of WB-DWI in the referred area, and to analyze the most potential advantage of WB-DWI in therapeutic monitoring and tumor staging. WB-DWI as a highly sensitive, completely non-invasive, well-tolerated and low price technique has a promising furture in tumor assessment. Profound clinical study is necessary for its further application improvement.

    2008-01-01

    Objective To investigate the feasibility of whole body diffusion weighted imaging (WB-DWI) in screening metastasis.Methods WB-DWI was performed in 24 patients diagnosed with various types of primary tumors. The three-dimensional maximum intensity projection reconstruction and black-and-white flip technique were used to observe metastatic lesions, and the results were compared with those of bone scintigraphy. Results By WB-DWI scanning sequence at b = 800 s/mm2, all the bone lesions found by bone scintigraphy in the cohort were well identified, and other lesions of soft tissue and organs were also well demonstrated. Its screening capability was equivalent with bone scintigraphy in screening metastases in bones (P = 0.062). Conclusion WB-DWI was practicable with the parameter settings attempted in metastases screening.

  19. Analysis of Genes Involved in Body Weight Regulation by Targeted Re-Sequencing.

    Anna-Lena Volckmar

    Full Text Available Genes involved in body weight regulation that were previously investigated in genome-wide association studies (GWAS and in animal models were target-enriched followed by massive parallel next generation sequencing.We enriched and re-sequenced continuous genomic regions comprising FTO, MC4R, TMEM18, SDCCAG8, TKNS, MSRA and TBC1D1 in a screening sample of 196 extremely obese children and adolescents with age and sex specific body mass index (BMI ≥ 99th percentile and 176 lean adults (BMI ≤ 15th percentile. 22 variants were confirmed by Sanger sequencing. Genotyping was performed in up to 705 independent obesity trios (extremely obese child and both parents, 243 extremely obese cases and 261 lean adults.We detected 20 different non-synonymous variants, one frame shift and one nonsense mutation in the 7 continuous genomic regions in study groups of different weight extremes. For SNP Arg695Cys (rs58983546 in TBC1D1 we detected nominal association with obesity (pTDT = 0.03 in 705 trios. Eleven of the variants were rare, thus were only detected heterozygously in up to ten individual(s of the complete screening sample of 372 individuals. Two of them (in FTO and MSRA were found in lean individuals, nine in extremely obese. In silico analyses of the 11 variants did not reveal functional implications for the mutations. Concordant with our hypothesis we detected a rare variant that potentially leads to loss of FTO function in a lean individual. For TBC1D1, in contrary to our hypothesis, the loss of function variant (Arg443Stop was found in an obese individual. Functional in vitro studies are warranted.

  20. Effect of 2,3,7,8-tetrachlorodibenzo-p-dioxin administration and high-fat diet on the body weight and hepatic estrogen metabolism in female C3H/HeN mice

    We studied the effect of administration of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) by i.p. injection once every 2 weeks in combination with a high-fat (HF) diet for 8 or 16 weeks on the body and organ weight changes as well as on the hepatic enzyme activity for estrogen metabolism in C3H/HeN female mice. Administration of TCDD at 100 μg/kg b.w. once every 2 weeks for 8 weeks increased the body weight by 46% in the HF diet-fed animals, but not in the regular diet-fed animals. This is the first observation suggesting that TCDD at a high dose (100 μg/kg b.w.), but not at lower doses (1 or 10 μg/kg b.w.), may have a strong obesity-inducing effect in C3H/HeN mice fed an HF diet. While TCDD increased liver weight and decreased thymus weight in animals, these effects were enhanced by feeding animals an HF diet. Metabolism studies showed that TCDD administration for 8 or 16 weeks increased the liver microsomal activity for the 2- and 4-hydroxylation of 17β-estradiol in animals fed a control diet, but surprisingly not in animals fed an HF diet. Treatment with TCDD dose-dependently increased the hepatic activity for the O-methylation of catechol estrogens in both control and HF diet-fed animals, and it also decreased the levels of liver microsomal sulfatase activity for hydrolysis of estrone-3-sulfate. TCDD did not significantly affect the hepatic enzyme activity for the glucuronidation or esterification of endogenous estrogens. It is suggested that enhanced metabolic inactivation of endogenous estrogens by hepatic estrogen-metabolizing enzymes in TCDD-treated, control diet-fed animals contributes importantly to the reduced incidence of estrogen-associated tumors in animals treated with TCDD
