    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.

    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.

    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.

  6. 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.

    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

  9. 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

  2. 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.

    Pich, Jordi; Bibiloni, Maria Del Mar; Pons, Antoni; Tur, Josep A

    2015-01-01

    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), or 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 become 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. PMID:26284248

  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...

  1. 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.

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

    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.

  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

    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

    The automotive industry stands in front of a great challenge, to decrease its impact on the environment. One important part in succeeding with this is to decrease the structural weight of the body structure and by that the fuel consumption or the required battery power. Carbon fibre composites are by many seen as the only real option when traditional engineering materials are running out of potential for further weight reduction. However, the automotive industry lacks experience working with ...

  9. Neurotrophic factor control of satiety and body weight.

    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

    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.

    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

    2012-09-01

    Full Text Available Background Urinary tract infections (UTI in infants may manifest in various ways and often appear without symptoms. Previous studies have reported that jaundice has been observed in infants aged less than reported that jaundice has been observed in study in the prevalence of UTI in infants with jaundice aged 2-8 weeks is warranted in order to improve diagnosing capability and provide prompt treatment. Objective To investigate the prevalence and profiles of UTI in infants with jaundice aged 2-8 weeks. Methods This cross-sectional study was carried out in June-December 2011 in infants with jaundice aged 2-8 weeks, Subjects were patients from the Epartment of Child Health, Cipto Mangunkusumo Hospital (CMS, as well as the Pediatric Polyclinics of Budi Kemuliaan and Thamrin Hospitals. All subjects underwent total, direct and indirect bilirubin examinations, urinalyses and urine cultures. Results Of the 110 subjects recruited, the prevalence of UTI was 18.2%. More boys than girl had UTIs (13 boys, 7 girls. The microorganism found in subjects with UTIs were Escherichia coli (10/20Klebsiella pneumoniae (8/20, and Enterobacter aerogenes (2/20. Indirect hyperbilirubenia was found in 5/20 subjects. There were more subjects with UTIs in the non-exclusively breastfed (8/20 and non-breastfed (8/20 groups than in the exclusively breastfed group (4/20, the full term gestational age (GA group (17/20 than the preterm GA group (3/20, and the normal birth weight group (15/20 than the low birth weight group (5/20. The median age of jaundice onset was 3.5 days (range 1-40 days, and the median duration of jaundice was 13.5 days (range 3-56 days. Conclusion The prevalence of UTI in infants aged 2-8 weeks with jaundice was 18.2%. More boys than girls had UTIs. The most common infecting microorganism found in our subjects was Escherichia coli. In daily medical practice, infants with prolonged jaundice of more than 2 weeks should be tested by urinalysis and urine cultures

  14. ESTIMATION OF LIVE BODY WEIGHT FROM LINEAR BODY MEASUREMENTS FOR FARTA SHEEP

    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.

    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.

    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

The data included the size and weight of certain organs. 18 refs

  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

    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. The NWO women showed significant increased value in the three indexes (p NWO women displayed a cluster of anthropometric characteristics (body fat mass percentage, leg indexes) not different to obese women ones. An appropriate diet-therapy and physical activity may be protecting NWO individuals from diabetes and cardiovascular diseases associated to preobese-obese women. PMID:16910350

    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.

  6. Influence of psychotropic drugs prescription on body weight increase

    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

    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

    RO Resende

    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.

  9. 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

    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.

    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.

    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.

  4. Asymptotic weight and maturing rate in mice selected for body conformation

    2000-01-01

    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.

    2014-06-01

    Full Text Available Background: Increased vascular stiffness is a marker of atherosclerosis, which is diagnosed in the early stages of diabetes II. Matrix metalloproteinases (MMPs and their tissue inhibitors (TIMPs are a family of proteolytic enzymes necessary for structure and function of great vessels. 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.

  8. Misperceived pre-pregnancy body weight status predicts excessive gestational weight gain: findings from a US cohort study

    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.)

    Cano, Stefan J.; Alderman, Amy; Soldin, Mark; Thoma, Achilles; Robson, Sam; Kaur, Manraj; Papas, Athanasios; Van Laeken, Nancy; Taylor, Valerie H.; Pusic, Andrea L.

    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.

    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

    2016-01-01

    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

    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.

    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.

    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-...

    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.

  1. 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)

    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.

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. 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

  13. 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

  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.

    Matheny, M.; Strehler, K.Y.E.; M. King; Tümer, N.; Scarpace, P. J.

    2014-01-01

    The present investigation examined whether leptin stimulation of ventral tegmental area (VTA) or nucleus of the solitary tract (NTS) has a role in body weight homeostasis independent of the medial basal hypothalamus (MBH). To this end, recombinant adeno-associated viral techniques were employed to target leptin overexpression or overexpression of a dominant negative leptin mutant (Leptin Antagonist). Leptin Antagonist overexpression in MBH or VTA increased food intake and body weight to simil...

  16. 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...

    Background and objective: Body weight and body mass index (BMI) are considered strong predictors of osteoporotic fractures, though optimal BMI levels remain unsettled. There are several studies conducted on women about the relationship between BMI and bone mineral density (BMD), and just a few so far on men. Therefore, the objective of current study was to analyze the relationship between weight and BMI and BMD measured in lumbar spine (L1-L4), femur neck and total hip in 64 men from Kosovo. ...

  18. Economic Development, Novelty Consumption, and Body Weight: Evidence from the East German Transition to Capitalism

    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...

    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...

  20. 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.

  1. 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.

  2. The Relationships among Body Weights and Linear Dimensions in Rabbit Breeds and Crosses

    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.

  3. 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.

    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

  13. 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.)

  14. Advances in weight loss surgery and body contouring after weight loss

    2010-06-01

    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

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.

    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...

    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.

    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

    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.

    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.

    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

    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.

    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

    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.

  9. 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.
