    Deep brain stimulation (DBS) is a neurosurgical technique that has now been available for some 25 years. It is used in the treatment of various motor disorders, e.g. Parkinson's disease (PD), essential tremor and dystonia, and neuropsychiatric illnesses, e.g. obsessive-compulsive disorder and Tourette syndrome. The surgical targets of DBS include the thalamic ventralis intermedius nucleus (Vim), the globus pallidus internus (GPi) and more recently the subthalamic nucleus (STN), currently considered as the reference target in the treatment of PD. In the last ten years, most studies in PD patients have described a rapid and marked weight gain in the months following DBS of the STN. This weight gain sometimes induces obesity and can have metabolic repercussions. The physiopathological mechanisms responsible for the weight gain are multifactorial (changes in energy metabolism and eating behaviour, reduction of motor complications, etc.). This review reports current knowledge concerning weight changes in patients treated by DBS with different surgical targets. It also describes the mechanisms responsible for weight gain and the health outcome for the patients.

    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.

    Background Since feed represents 70% of the total cost in poultry production systems, an animal’s ability to convert feed is an important trait. In this study, residual feed intake (RFI) and residual body weight gain (RG), and their linear combination into residual feed intake and body weight gain (RIG) were studied to estimate their genetic parameters and analyze the potential differences in feed intake between the top ranked birds based on the criteria for each trait.

    Full Text Available Overweight and obesity are frequently reported to be a significant issue in schizophrenia resulting in the inherent complications of these disorders. Body weight gain also commonly results from treatment with the most tolerable and efficacious pharmacological treatments, second-generation antipsychotics. However there are numerous other factors that contribute to increased body mass in individuals with schizophrenia prior to the initiation of treatment. With prior research indicating that individuals with schizophrenia have higher rates of overweight and obesity before treatment. Therefore this article provides a review of pertinent issues associated with body weight gain in schizophrenia in an attempt to delineate the impact of both the disease and treatment upon body weight gain. The results of the review indicate that body weight gain in schizophrenia occurs from both psychosocial and biological factors that are further compounded by antipsychotic treatment. The article concludes with recommendations for future research.

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

    The present study was aimed at assessing alterations in serum PCT in terms of its relation to body weight gain in pulmonary tuberculosis (PTB) patients undergoing treatment. Among patients (25-75 years) diagnosed with pulmonary tuberculosis, those that were new smear positive, showed sputum conversion at the end of 2 months and were declared clinically cured at the end of 6 months, were included in the study (n = 40). Serum procalcitonin was determined by BRAHMS PCT-Q kit. Patients were divided into two study groups-Group 1 (n = 21; serum PCT > 2 ng/ml at diagnosis), Group 2 (n = 19; serum PCT > 10 ng/ml at diagnosis). Body weights of all patients were obtained at three different time points, PTB-0 (at diagnosis), PTB-2 (after 2 months of intensive treatment) and PTB-6 (after 6 months of treatment). In both groups, mean body weights at PTB-2 and PTB-6 were significantly higher than those at PTB-0 and at PTB-6 were significantly higher than those at PTB-2. However, percentage body weight gain following 2 months of intensive treatment was higher in group 1 (4.05 % gain, p < 0.01) than in group 2 (2.75 % body weight gain, p < 0.05). Thus, the percentage gain in group 1 was tending more towards the desirable minimum gain of 5 % during intensive phase. Increase in serum PCT levels in pulmonary tuberculosis is inversely associated with body weight gain during treatment. Thus, PCT could play a role in regulation of body weight gain in anorectic conditions like tuberculosis.

    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

    We evaluated body weight changes in patients with Parkinson's disease (PD) after electrode implantation for deep brain stimulation (DBS) in the subthalamic nucleus (STN) in relation to clinical improvement. Thirty PD patients who received STN DBS were included (22 men, 8 women; mean age, 60.0 +/- 7.1 years; mean PD duration, 13.5 +/- 3.7 years; mean body mass index [BMI], 21.6 +/- 3.0 kg/m2). Body weight, physical activity, and Unified Parkinson's Disease Rating Scale (UPDRS) scores were noted before and 3 and 12 months after the procedure. Significant weight gain occurred in 29 patients; the mean increase was 14.8 +/- 9.8% of initial body weight in 1 year. Of the patients, 46.5% reported weight gain in the first 3 months, 21.4% gradual weight gain in the first 6 months, and 32.1% a slow increase for 1 year. Mean BMI increased up to 24.7 +/- 3.7 kg/m2. After 1 year, mean UPDRS motor score improved significantly in off and in on; and therapy complications improved by 91.0 +/- 17.0%. BMI changes at 3 and 12 months were significantly correlated to dyskinesia score changes, and levodopa dosage was not. In PD, STN DBS produces not only symptom control, but also weight gain. DBS candidates should be given nutritional counseling before the intervention to prevent rapid and/or excessive weight gain.

    Chronic bilateral subthalamic stimulation leads to a spectacular clinical improvement in patients with motor complications. However, the post-operative body weight gain involved may limit the benefits of surgery and induce critical metabolic disorders. Twenty-four Parkinsonians (61.1 +/- 1.4 years) were examined 1 month before (M - 1) and 3 months after (M + 3) surgery. Body composition and energy expenditure (EE) were measured (1) over 36 h in calorimetric chambers (CC) with rigorous control of food intakes and activities [sleep metabolic rate, resting activities, meals, 3 or 4 sessions of 20 min on a training bicycle at 13 km/h and daily EE] and (2) in resting conditions (basal metabolic rate) during an acute L-dopa challenge (M - 1) or according to acute 'off' and 'on' stimulation (M + 3). Before surgery, EE was compared between the Parkinsonian patients and healthy subjects matched for height and body composition (metabolic rate during sleep, daily EE) or matched to predicted values (basal metabolic rate). Before surgery, in Parkinsonian men but not women, (1) daily EE was higher while sleep metabolic rate was lower compared to healthy matched men (+9.2 +/- 3.9 and -8.2 +/- 2.3%, respectively, P weight gain. Parkinson's disease is associated with profound alterations in the central control of energy metabolism. Normalization of energy metabolism after DBS-STN implantation may favour body weight gain, of which quality was gender specific. As men gained primarily fat-free mass, a reasonable weight gain may be tolerated, in contrast with women who gained only fat. Other factors such as changes in free-living physical activity may help to limit body weight gain in some patients.

    Obesity during pregnancy may be correlated with an adverse nutritional status affecting pregnancy and offspring outcomes. We examined the associations of prepregnancy body mass index and gestational weight gain with plasma fatty acid concentrations in mid-pregnancy. This study was embedded in a population-based prospective cohort study among 5636 women. We obtained prepregnancy body mass index and maximum weight gain during pregnancy by questionnaires. We measured concentrations of saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), n-3 polyunsaturated fatty acid (n-3 PUFA) and n-6 polyunsaturated fatty acid (n-6 PUFA) at a median gestational age of 20.5 (95% range 17.1-24.9) weeks. We used multivariate linear regression models. As compared to normal weight women, obese women had higher total SFA concentrations [difference: 0.10 standard deviation (SD) (95% Confidence Interval (CI) 0, 0.19)] and lower total n-3 PUFA concentrations [difference: - 0.11 SD (95% CI - 0.20, - 0.02)]. As compared to women with sufficient gestational weight gain, those with excessive gestational weight gain had higher SFA concentrations [difference: 0.16 SD (95% CI 0.08, 0.25)], MUFA concentrations [difference: 0.16 SD (95% CI 0.08, 0.24)] and n-6 PUFA concentrations [difference: 0.12 SD (95% CI 0.04, 0.21)]. These results were not materially affected by adjustment for maternal characteristics. Our results suggest that obesity and excessive weight gain during pregnancy are associated with an adverse fatty acids profile. Further studies are needed to assess causality and direction of the observed associations.

    2015-01-01

    We developed a novel decision-making paradigm that allows us to apply prospect theory in behavioral economics to body mass. 67 healthy young adults completed self-report measures and two decision-making tasks for weight-loss, as well as for monetary rewards. We estimated risk-related preference and loss aversion parameters for each individual, separately for weight-loss and monetary rewards choice data. Risk-seeking tendency for weight-loss was positively correlated with body mass index in individuals who desired to lose body weight, whereas the risk-seeking for momentary rewards was not. Risk-seeking for weight-loss was correlated to excessive body shape preoccupations, while aversion to weight-gain was correlated with self-reports of behavioral involvement for successful weight-loss. We demonstrated that prospect theory can be useful in explaining the decision-making process related to body mass. Applying prospect theory is expected to advance our understanding of decision-making mechanisms in obesity, which might prove helpful for improving healthy choices.

    In patients with Parkinson's disease, significant weight gain following chronic deep brain stimulation (DBS) has been reported. Recently, relevant weight gain could be demonstrated also following subthalamic nucleus DBS in patients with primary cervical dystonia. Prospective analyses of body weight changes following DBS in patients with dystonia, however, have not been published so far. We aimed to analyse the changes of body weight following DBS in patients with dystonia. The body mass index (BMI) of 17 consecutive patients with segmental or generalised dystonia (mean age 54.6 ± 16.1 years) treated with bilateral DBS of the globus pallidus internus (GPi) (n = 14) or the thalamic ventral intermediate nucleus (n = 3) was measured preoperatively (pre-OP) and at three follow-up (FU) time points post-DBS surgery (FU1 = 7 months, FU2 = 17 months, FU3 = 72 months). All patients benefited from marked improvement in their dystonia. The mean BMI pre-OP (SD) was 22.5 (±3.7) kg/m(2) and increased stepwise to 24.0 (±3.3) kg/m(2) at FU1, 24.4 (±3.7) kg/m(2) at FU2 and 24.9 (±3.7) kg/m(2) at FU3 (p weight gain, in particular during the first 6 months post-OP. This probably is a result of improvement of dystonic motor symptoms and recovery of eating dysfunction rather than a target-specific phenomenon.

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

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

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

Adult male C57BL/6 mice were submitted to two 1.5-h daily swimming sessions (T, N = 18, 5 days/week for 4 weeks or maintained sedentary (S, N = 15. Citrate synthase activity increased significantly in the T group (P < 0.05. S mice had a substantial weight gain compared to T mice (4.06 ± 0.43 vs 0.38 ± 0.28 g, P < 0.01. WAT mass, adipocyte size, and the weights of gastrocnemius and soleus muscles, lung, kidney, and adrenal gland were not different. Liver and heart were larger and the spleen was smaller in T compared to S mice (P < 0.05. Food intake was higher in T than S mice (4.7 ± 0.2 vs 4.0 ± 0.3 g/animal, P < 0.05 but oxygen consumption at rest did not differ between groups. T animals showed higher serum leptin concentration compared to S animals (6.37 ± 0.5 vs 3.11 ± 0.12 ng/mL. WAT gene expression pattern obtained by transcription factor adipocyte determination and differentiation-dependent factor 1, fatty acid synthase, malic enzyme, hormone-sensitive lipase, adipocyte lipid binding protein, leptin, and adiponectin did not differ significantly between groups. Collectively, our results showed that PT prevents BW gain and maintains WAT mass due to an increase in food intake and unchanged resting metabolic rate. These responses are closely related to unchanged WAT gene expression patterns.

Citrate synthase activity increased significantly in the T group (P < 0.05). S mice had a substantial weight gain compared to T mice (4.06 ± 0.43 vs 0.38 ± 0.28 g, P < 0.01). WAT mass, adipocyte size, and the weights of gastrocnemius and soleus muscles, lung, kidney, and adrenal gland were not different. Liver and heart were larger and the spleen was smaller in T compared to S mice (P < 0.05). Food intake was higher in T than S mice (4.7 ± 0.2 vs 4.0 ± 0.3 g/animal, P < 0.05) but oxygen consumption at rest did not differ between groups. T animals showed higher serum leptin concentration compared to S animals (6.37 ± 0.5 vs 3.11 ± 0.12 ng/mL). WAT gene expression pattern obtained by transcription factor adipocyte determination and differentiation-dependent factor 1, fatty acid synthase, malic enzyme, hormone-sensitive lipase, adipocyte lipid binding protein, leptin, and adiponectin did not differ significantly between groups. Collectively, our results showed that PT prevents BW gain and maintains WAT mass due to an increase in food intake and unchanged resting metabolic rate. These responses are closely related to unchanged WAT gene expression patterns.

    Obesity is reaching epidemic proportions worldwide, and is associated with chronic illnesses such as diabetes, cardiovascular disease, hypertension and dyslipidemias (metabolic syndrome). Commonly held causes of obesity are overeating coupled with a sedentary lifestyle. However, it has also been postulated that exposure to endocrine disrupting chemicals (EDCs) may be related to the significant increase in the prevalence of obesity and associated diseases. In the present study, developmental and reproductive effects of lifelong exposure to environmentally relevant concentrations of two natural mixtures of persistent organic pollutants (POPs) were investigated using classical and molecular methods in a controlled zebrafish model. The mixtures used were extracted from burbot (Lota lota) liver originating from freshwater systems in Norway (Lake Mjøsa and Lake Losna). The concentration of POPs in the zebrafish ranged from levels detected in wild fish (Lake Mjøsa and Lake Losna), to concentrations reported in human and wildlife populations. Phenotypic effects observed in both exposure groups included (1) earlier onset of puberty, (2) elevated male/female sex ratio, and (3) increased body weight at 5 months of age. Interestingly, genome-wide transcription profiling identified functional networks of genes, in which key regulators of weight homeostasis (PPARs, glucocoricoids, CEBPs, estradiol), steroid hormone functions (glucocoricoids, estradiol, NCOA3) and insulin signaling (HNF4A, CEBPs, PPARG) occupied central positions. The increased weight and the regulation of genes associated with weight homeostasis and insulin signaling observed in the present study suggest that environmental pollution may affect the endocrine regulation of the metabolism, possibly leading to increased weight gain and obesity.

    Full Text Available Previous research has shown that mifepristone can prevent and reverse weight gain in animals and human subjects taking antipsychotic medications. This proof-of-concept study tested whether a more potent and selective glucocorticoid receptor antagonist could block dietary-induced weight gain and increase insulin sensitivity in mice. Ten-week-old, male, C57BL/6J mice were fed a diet containing 60% fat calories and water supplemented with 11% sucrose for 4 weeks. Groups (=8 received one of the following: CORT 108297 (80 mg/kg QD, CORT 108297 (40 mg/kg BID, mifepristone (30 mg/kg BID, rosiglitazone (10 mg/kg QD, or vehicle. Compared to mice receiving a high-fat, high-sugar diet plus vehicle, mice receiving a high-fat, high-sugar diet plus either mifepristone or CORT 108297 gained significantly less weight. At the end of the four week treatment period, mice receiving CORT 108297 40 mg/kg BID or CORT 108297 80 mg/kg QD also had significantly lower steady plasma glucose than mice receiving vehicle. However, steady state plasma glucose after treatment was not highly correlated with reduced weight gain, suggesting that the effect of the glucocorticoid receptor antagonist on insulin sensitivity may be independent of its mitigating effect on weight gain.

    Anorexia nervosa (AN), a severe mental disorder with an onset during adolescence, has been found to be difficult to treat. Identifying variables that predict long-term outcome may help to develop better treatment strategies. Since body image distortion and weight gain are central elements of diagnosis and treatment of AN, the current study investigated perceptual body image distortion, defined as the accuracy of evaluating one's own perceived body size in relation to the actual body size, as well as total and early weight gain during inpatient treatment as predictors for long-term outcome in a sample of 76 female adolescent AN patients. Long-term outcome was defined by physical, psychological and psychosocial adjustment using the Morgan-Russell outcome assessment schedule as well as by the mere physical outcome consisting of menses and/or BMI approximately 3 years after treatment. Perceptual body image distortion and early weight gain predicted long-term outcome (explained variance 13.3 %), but not the physical outcome alone. This study provides first evidence for an association of perceptual body image distortion with long-term outcome of adolescent anorexia nervosa and underlines the importance of sufficient early weight gain.

    The relationship between serum growth factors and body weight gain was examined in five Dorset lambs. The lambs were weighed and bled by jugular puncture at 2-week intervals between 2 and 18 weeks of age. Somatomedin-like activity (Sm) declined from initially high concentrations at 2 weeks to fairly constant concentrations between 6 and 18 weeks. Relative weight gain--i.e., gain expressed as a percentage of body weight--declined in a manner similar to that of Sm. Mean relative weight gain and mean Sm for the eight 2-week intervals were significantly related (r = .84). Absolute body weight gain--i.e., gain expressed in kilograms--remained fairly constant throughout the study and was not significantly correlated to Sm (r = .15). Serum fibroblast proliferative activity (FPA) was measured as a possible indicator of collective activities of serum growth factors. FPA initially followed a pattern similar to that of Sm, decreasing between 2 and 6 weeks and plateauing until 12 weeks. After 12 weeks, FPA increased to concentrations similar to those observed at 2 weeks. The increase in FPA after 12 weeks was apparently due to an increase in a non-Sm growth factor and had no obvious relationship to body weight changes. Results of the in vitro cell assay system might have been more meaningful if cell type(s) other than WI-38 fibroblasts (e.g., myogenic cells) had been used for estimating collective activities of serum mitogenic factors. The data suggest that serum Sm-like activity may be important in the regulation of growth in sheep.

    Full Text Available ABSTRACTThe objective of this study was to evaluate the effects of 1% dietary glutamic acid on the body weight, intestinal morphometry, and anti-Newcastle antibody titers of broiler chickens submitted to heat stress. One-d-old male broiler chicks (n=120 were distributed according to a 2 x 2 factorial design with two environmental temperatures (thermoneutral or heat stress and two diets (with 0 or 1% glutamic acid. Heat stress temperature was constantly maintained (24h/day 5 ºC higher than the thermoneutral temperature. Diets supplied the nutritional requirements of broilers in the pre-starter (1 to 7d and starter (8 to 21d phases. Birds were vaccinated against Newcastle disease on d 7 via eye drop. On days 5, 10, 15, and 20, individual body weight was determined, serum samples were collected from five birds, and duodenum samples were collected from four birds per treatment. Serum anti-Newcastle antibody titers were determined by enzyme immunoassay and transformed into log10. Villus height, crypt depth, and villus: crypt ratio were measured in the duodenum. Data were analyzed by ANOVA. Chronic heat stress negatively affected body weight and intestinal morphometry during the pre-starter and starter phases, but had no effect on antibody titers. Dietary glutamic acid supplementation (1% improved body weight and intestinal integrity of birds submitted to heat stress when compared with non-supplemented and heat-stressed birds.

    2012-07-01

    The purpose was to determine the relationship between insulin resistance (IR) and risk of gaining body fat percentage (BF%), body weight, and abdominal fat over 18 months. A prospective cohort study was conducted using a sample of 226 women. IR was assessed using fasting blood insulin and glucose levels to calculate homeostatic model assessment (HOMA). Participants were divided into High (4th quartile) Moderate (2nd and 3rd quartiles), and Low (1st quartile) HOMA categories. BF% was estimated using plethysmography (Bod Pod), weight was measured in a standard swimsuit, and abdominal fat was indexed using the average of two circumferences taken at the umbilicus. Participants wore accelerometers and completed weighed food logs for 7 consecutive days to control for the effect of physical activity (PA) and energy intake, respectively. On average, women in the High HOMA group decreased in BF% (-0.48 ± 3.60), whereas those in the Moderate (0.40 ± 3.66) and Low HOMA (1.17 ± 3.15) groups gained BF% (F = 5.4, P = 0.0211). Changes in body weight showed a similar dose-response relationship (F = 4.7, P = 0.0317). However, baseline IR was not predictive of changes in abdominal fat (F = 0.8, P = 0.3635). Controlling for several covariates had little effect on gains in BF% and weight, but adjusting for initial BF% and/or initial weight nullified changes in BF% and weight across the IR groups. In conclusion, women with High HOMA tend to gain significantly less BF% and weight than women with low or moderate HOMA. The decreased risk appears unrelated to several covariates, except initial BF% and weight levels, which seem to play key roles in the relationships.

    Dietary flavonoids may protect against cardiovascular diseases (CVD). Increased circulating lipid levels and hepatic lipid accumulation are known risk factors for CVD. The aim of this study was to investigate the effects and underlying molecular mechanisms of the flavonoid quercetin on hepatic lipid metabolism in mice with high-fat diet induced body weight gain and hepatic lipid accumulation. Adult male mice received a 40 energy% high-fat diet without or with supplementation of 0.33 % (w/w) quercetin for 12 weeks. Body weight gain was 29 % lower in quercetin fed mice (p lipid accumulation to 29 % of the amount present in the control mice (p lipid profiling revealed that the supplementation significantly lowered serum lipid levels. Global gene expression profiling of liver showed that cytochrome P450 2b (Cyp2b) genes, key target genes of the transcription factor constitutive androstane receptor (Car; official symbol Nr1i3), were downregulated. Quercetin decreased high-fat diet induced body weight gain, hepatic lipid accumulation and serum lipid levels. This was accompanied by regulation of cytochrome P450 2b genes in liver, which are possibly under transcriptional control of CAR. The quercetin effects are likely dependent on the fat content of the diet.

    In an earlier work (S. E. Swithers & T. L. Davidson, 2008), rats provided with a fixed amount of a yogurt diet mixed with saccharin gained more weight and showed impaired caloric compensation relative to rats given the same amount of yogurt mixed with glucose. The present 4 experiments examined the generality of these findings and demonstrated that increased body weight gain was also demonstrated when animals consumed a yogurt diet sweetened with an alternative high-intensity sweetener (acesulfame potassium; AceK) as well as in animals given a saccharin-sweetened base diet (refried beans) that was calorically similar but nutritionally distinct from low-fat yogurt. These studies also extended earlier findings by showing that body weight differences persist after saccharin-sweetened diets are discontinued and following a shift to a diet sweetened with glucose. In addition, rats first exposed to a diet sweetened with glucose still gain additional weight when subsequently exposed to a saccharin-sweetened diet. The results of these experiments add support to the hypothesis that exposure to weak or nonpredictive relationships between sweet tastes and caloric consequences may lead to positive energy balance.

    Two F2 generations of an intercross between Hampshire boars and Hungarian Large White sows were produced to estimate the effects of the porcine KIT genotypes (II, Ii and ii) on quantitative and qualitative haematological indices, on piglet birth weight and growth performance until weaning. Piglets carrying the I allele had significantly fewer lymphocytes (p = 0.041) than the ii homozygotes, heterozygotes had measures between the two homozygotes. KIT genotypes did not influence white blood cells, red blood cells, haemoglobin and haematocrite. II genotype piglets were significantly lighter at birth than the ones carrying the recessive i allele, the effect of KIT genotypes on gain until weaning was not significant, but II piglets tended to gain less. The results of this study support the hypothesis of M. Johansson, H. Ellegren, L. Marklund, U. Gustavsson, E. Ringmar-Cederberg, K. Andersson, I. Edfors-Lilja and L. Andersson [(1992) Genomics, 14, 965] that the pleiotrophic effect of the porcine KIT mutations on haematopoietic cells must be mild.

    Highlights: • The expression of Jazf1 in the liver suppressed lipid accumulation. • Jazf1 significantly increases transcription of fatty acid synthase. • Jazf1 plays a critical role in the regulation of energy and lipid homeostasis. • Jazf1 associates the development of metabolic disorder. • Jazf1 may provide a new therapeutic target in the management of metabolic disorder. - Abstract: Jazf1 is a 27 kDa nuclear protein containing three putative zinc finger motifs that is associated with diabetes mellitus and prostate cancer; however, little is known about the role that this gene plays in regulation of metabolism. Recent evidence indicates that Jazf1 transcription factors bind to the nuclear orphan receptor TR4. This receptor regulates PEPCK, the key enzyme involved in gluconeogenesis. To elucidate Jazf1’s role in metabolism, we fed a 60% fat diet for up to 15 weeks. In Jazf1 overexpression mice, weight gain was found to be significantly decreased. The expression of Jazf1 in the liver also suppressed lipid accumulation and decreased droplet size. These results suggest that Jazf1 plays a critical role in the regulation of lipid homeostasis. Finally, Jazf1 may provide a new therapeutic target in the management of obesity and diabetes.

    BACKGROUND: The obesogenic potential of high-fat diets (HFD) in rodents is attenuated when the protein:carbohydrate ratio is increased. However, it is not known if intake of an HFD irrespective of the protein:carbohydrate ratio and in the absence of weight gain, affects glucose homeostasis...... no differences were observed during insulin tolerance tests. The hyperinsulinemic euglycemic clamp revealed tissue-specific effects on glucose homeostasis in all HFD-fed groups. HFD-fed mice exhibited decreased insulin-stimulated glucose uptake in white but not in brown adipose tissue, and sustained endogenous...... glucose production under insulin-stimulated conditions. We observed no impairment of insulin-stimulated glucose uptake in skeletal muscles of different fiber type composition.

  7. Energy Gap in the Aetiology of Body Weight Gain and Obesity: A Challenging Concept with a Complex Evaluation and Pitfalls

    2014-01-01

    Full Text Available The concept of energy gap(s is useful for understanding the consequence of a small daily, weekly, or monthly positive energy balance and the inconspicuous shift in weight gain ultimately leading to overweight and obesity. Energy gap is a dynamic concept: an initial positive energy gap incurred via an increase in energy intake (or a decrease in physical activity is not constant, may fade out with time if the initial conditions are maintained, and depends on the ‘efficiency' with which the readjustment of the energy imbalance gap occurs with time. The metabolic response to an energy imbalance gap and the magnitude of the energy gap(s can be estimated by at least two methods, i.e. i assessment by longitudinal overfeeding studies, imposing (by design an initial positive energy imbalance gap; ii retrospective assessment based on epidemiological surveys, whereby the accumulated endogenous energy storage per unit of time is calculated from the change in body weight and body composition. In order to illustrate the difficulty of accurately assessing an energy gap we have used, as an illustrative example, a recent epidemiological study which tracked changes in total energy intake (estimated by gross food availability and body weight over 3 decades in the US, combined with total energy expenditure prediction from body weight using doubly labelled water data. At the population level, the study attempted to assess the cause of the energy gap purported to be entirely due to increased food intake. Based on an estimate of change in energy intake judged to be more reliable (i.e. in the same study population and together with calculations of simple energetic indices, our analysis suggests that conclusions about the fundamental causes of obesity development in a population (excess intake vs. low physical activity or both is clouded by a high level of uncertainty.

    Patients with high-output small bowel ostomies are at risk for total body sodium depletion (TBSD), defined as a urine sodium level children. The records of all children beyond the age of infancy with a small bowel ostomy cared for in our Children's Intestinal Rehabilitation Program from 2010-2012 were reviewed. Four patients between the ages of 18 months and 19 years were identified as having TBSD. All 4 patients experienced unintentional weight loss, despite adequate energy intake based on calculated needs, which was associated with a urine sodium level ≤10 mmol/L. With the supplementation of sodium, either enteral or intravenous, all patients demonstrated improved weight gain and correction of TBSD. The following cases suggest that the relationship between TBSD and FTT may extend well beyond the neonatal period and possibly into adulthood. We advise that patients of all ages with high stoma output have routine urine sodium levels checked, particularly in the setting of weight loss or poor gain. Furthermore, instances of TBSD should be treated with sodium supplementation. Further research is needed to better understand the relationship between TBSD and FTT and to establish intervention guidelines.

    Neonatal maternal separation (MS) in rats has been reported to result in permanent dysfunctions of the hypothalamic-pituitary-adrenal axis and the development of anxiety- and depression-like behaviors later in life. In this study, we examined the effects of post-weaning social isolation stress on food intake and body weight gain of rats with MS experience. MS was performed daily for 180 min during the first 2 weeks of birth and nonhandled control (NH) pups were left undisturbed. Weanling male pups were caged either in a group of three or singly (social isolation), and then subjected to behavioral sessions for anxiety- or depression-like behaviors at 2 months of age. Social isolation following MS experience, but neither MS nor social isolation alone, significantly increased food intake and weight gain. MS pups showed increased immobility in forced swim test, compared to NH pups, regardless of their housing conditions. In elevated plus maze test, group-caged MS pups spent less time in the open arms and more time in the closed arms than group-caged NH pups, but social isolation did not further affect the arm stay of MS pups. However, statistical analyses revealed an interaction between MS and social isolation not only in the time spent in each arms, but also in defecation scores during the ambulatory activity test. These results suggest that post-weaning social isolation may promote hyperphagia and weight gain in young rats that experienced neonatal maternal separation, perhaps, in relation with its impact on the psycho-emotional behaviors of MS pups.

    Full Text Available The aims of study were to evaluate the use of fermented of oil palm fronds (FOPF on body weight gain and meat quality of goat. This experiment was arranged in Completely Randomized Design with 3 treatments i.e. R1 (grass 0%: FOPF 100%, R2 (grass 50%: FOPF 50% and R3 (grass 100%: FOPF 0% and 5 replications. The parameters of the study were feed intake, average daily gain (ADG, weight and percentage of carcass and meat quality. The results indicated that feed intake and meat quality of goat was not affected by treatment, but the average daily gain, carcass weight, and percentage of carcass, was affected by the differences of percentage of FOPF in the pellet complete feed. The best ration was in the R1 ration (grass 0%: FOPF 100% that significantly different (P<0.05 from the other rations. The feed intake tended to be higher in goat fed R1 (895.87 g/d compared to those in goat with the R2 (854.38 g/d and R3 (851.53 g/d. The average daily gain and carcass weight were higher in goat fed R1 ration compared to those in goat fed R2 and R3. Consequently, the carcass percentage in R1 was higher than those in R2 and R3. The carcass percentage was ranged from 38.41-41.38%. The Ribeye area was higher in goat fed R1 (9.73 cm2 than R2 (8.34 cm2 and R3 (7.76 cm2. In this study, the protein content of goat meat was ranged from 19.06 to 20.71%, lipid content was ranged from 0.703 to 1.106% and water content was range from 72.45% to 74.12%, in which were not different among the treatments. It can be concluded that the use of FOPF in a complete feed could improve performance and meat quality of goat.

    Development and characterization of animal models of depression are essential for fully understanding the pathogenesis of depression in humans. We made and analyzed a mouse model exhibiting social deficit and hyperphagia-like behavior using a subchronic and mild social defeat stress (sCSDS) paradigm. The body weight, food and water intake of mice were monitored during a test period, and their behaviors and serum components were analyzed at two stages: immediately after the sCSDS period and 1 month after the sCSDS. The body weight and food intake of defeated mice were significantly higher than control mice at the sCSDS period, and these differences were sustained until 1 month after the sCSDS, whereas the water intake of defeated mice was significantly higher than control mice for the period of sCSDS only. Behavioral analyses revealed that the defeated mice exhibit significant social aversion to unfamiliar mice in a social interaction test and a trend of anxiety-like behavior in an elevated-plus maze test. Possibly due to polydipsia-like symptoms, defeated mice had significantly lower levels of albumin and blood urea nitrogen than control mice immediately after the sCSDS period but not at 1 month after sCSDS. The present study revealed that our sCSDS mice keep much more water in their body than control mice. This study reports the first step toward an understanding of the mechanisms of stress-induced overhydration, over-eating and resultant weight gain.

    Full Text Available The aim of this study was to evaluate the effects of resistance exercise, such as weight-lifting (WL on the biochemical parameters of lipid metabolism and cardiovascular disease risk in the rats fed casein (control or whey protein (WP diets. Thirty-two male Fisher rats were randomly assigned to sedentary or exercise-trained groups and were fed control or WP diets. The WL program consisted of inducing the animals to perform the sets of jumps with weights attached to the chest. After seven weeks, arteriovenous blood samples were collected for analysis. The WL or WP ingestion were able to improve the lipid profile, reducing the TC and non-HDL cholesterol concentrations, but only WP treatment significantly increased the serum HDL concentrations, thereby also affecting the TC/HDL and HDL/non-HDL ratios. However, WL plus WP was more effective in improving the HDL/non-HDL ratio than the exercise or WP ingestion alone and the body weight gain than exercise without WP ingestion.

    Systemic inflammation may mediate the association between chronic obstructive pulmonary disease (COPD) and extrapulmonary comorbidities. We measured high-sensitivity C-reactive protein (hs-CRP) in COPD and quantified the effect modification by body weight change and sex. Using data from the Swiss study on Air Pollution and Lung Diseases in Adults (SAPALDIA; n = 5,479) with measurements of forced expiratory volume in 1 s (FEV(1)), body weight and hs-CRP, we examined the association of hs-CRP and categories of body weight change (lost weight and weight gained 0-5%, 5-9%, 9-14% and >14%) with fast FEV(1) decline. hs-CRP was elevated both in association with fast FEV(1) decline and body weight gain. Subjects with fast FEV(1) decline and weight gain (>14%) had higher hs-CRP (2.0 mg L(-1) for females versus 1.6 mg L(-1) for males). After adjustment for age, smoking, physical activity, hormonal therapy and diabetes, elevated hs-CRP (>3 mg) was found to be more likely in subjects with fast FEV(1) decline (OR(males) 1.38, OR(females) 1.42) and in those with weight gain >14% (OR(males) 2.04, OR(females) 4.51). The association of weight gain and fast FEV(1) decline predicts a higher level of systemic inflammation. Since the effect of weight gain on systemic inflammation is larger in females than in males, weight gain may be a risk factor for extrapulmonary comorbidities in females with COPD.

    Recent data suggests that abnormal maternal pre-pregnancy body mass index (BMI) or gestational weight gain (GWG) is associated with unfavorable delivery outcomes. However, limited clinical evidence is available to support this correlation in China. Participating 510 mother-infant pairs were recruited from the Shanghai First Maternity and Infant Hospital, China, between January 1st and 30th 2016. Maternal pre-pregnancy BMI was categorized according to the China’s classification and GWG according to the 2009 Institute of Medicine recommendations (IOM). Linear regression tested the associations between pre-pregnancy BMI or GWG and length of gestation, birthweight, length, and head circumference. Logistic regression assessed the associations between pre-pregnancy BMI or GWG and macrosomic, small- (SGA) and large- (LGA) for-gestational-age infants. Overweight/obese women showed increased length of gestation and birthweight, but did not have a higher risk of macrosomic and LGA infants compared with normal weight women. Women with excessive GWG showed increased length of gestation, birthweight, length, and head circumference, and were more likely to deliver macrosomic and LGA infants compared with women with adequate GWG. Although a relatively low proportion of women from Shanghai area are overweight/obese or exhibit excessive GWG, both high pre-pregnancy BMI and excessive GWG influence perinatal outcomes.

    VGF (non-acronymic) was first highlighted to have a role in energy homeostasis through experiments involving dietary manipulation in mice. Fasting increased VGF mRNA in the Arc and levels were subsequently reduced upon refeeding. This anabolic role for VGF was supported by observations in a VGF null (VGF-/-) mouse and in the diet-induced and gold-thioglucose obese mice. However, this anabolic role for VGF has not been supported by a number of subsequent studies investigating the physiological effects of VGF-derived peptides. Intracerebroventricular (ICV) infusion of TLQP-21 increased resting energy expenditure and rectal temperature in mice and protected against diet-induced obesity. Similarly, ICV infusion of TLQP-21 into Siberian hamsters significantly reduced body weight, but this was due to a decrease in food intake, with no effect on energy expenditure. Subsequently NERP-2 was shown to increase food intake in rats via the orexin system, suggesting opposing roles for these VGF-derived peptides. Thus to further elucidate the role of hypothalamic VGF in the regulation of energy homeostasis we utilised a recombinant adeno-associated viral vector to over-express VGF in adult male Siberian hamsters, thus avoiding any developmental effects or associated functional compensation. Initially, hypothalamic over-expression of VGF in adult Siberian hamsters produced no effect on metabolic parameters, but by 12 weeks post-infusion hamsters had increased oxygen consumption and a tendency to increased carbon dioxide production; this attenuated body weight gain, reduced interscapular white adipose tissue and resulted in a compensatory increase in food intake. These observed changes in energy expenditure and food intake were associated with an increase in the hypothalamic contents of the VGF-derived peptides AQEE, TLQP and NERP-2. The complex phenotype of the VGF-/- mice is a likely consequence of global ablation of the gene and its derived peptides during development, as well

    The biological activities of cannabidiol (CBD), a major non-psychotropic constituent of the fiber-type cannabis plant, have been examined in detail (e.g., CBD modulation of body weight in mice and rats). However, few studies have investigated the biological activities of cannabidiol-2',6'-dimethyl ether (CBDD), a dimethyl ether derivative of the parent CBD. We herein focused on the effects of CBDD on body weight changes in mice, and demonstrated that it stimulated body weight gain in apolipoprotein E (ApoE)-deficient BALB/c. KOR/Stm Slc-Apoe(shl) mice, especially between 10 and 20 weeks of age.

    Full Text Available Gestational weight gain (GWG may interfere in perinatal outcomes and also cause future problems throughout woman’s life. The aim of this population-based study is to evaluate the GWG in Campinas city, southeast of Brazil. A total of 1052 women, who delivered in the three major maternity hospitals in Campinas, were interviewed during postpartum period. The general average of GWG was 13.08±6.08. Of total women, 13.6% were obese and 24.6% were overweight and, in these groups, 55.9% and 53.7%, respectively, exceeded GWG according to the Institute of Medicine recommendations. 6.2% of total women had low body mass index (BMI and 35.5% in this group had insufficient GWG. Overweight and obese women had a higher risk of excessive GWG and delivery by c-section. The c-section rate was 58.9% and increased according to GWG. Prematurity was more prevalent first in obese and then in low BMI women. Considering the high BMI in women in reproductive age, it is necessary to take effective guidelines about lifestyle and nutritional orientation in order to help women reach adequate GWG. All of them could improve prenatal outcomes and women’s heath as a whole.

    Full Text Available Caffeine (120 mg/kg was administered intragastrically to pregnant rats daily on gestational days 8-21. An increase in serum concentration of glucose and total protein was found in animals, which were given caffeine. The protein content proved to be highly significant in the experimental group of animals. The control group showed a negative interdependence between body weight gain and glucose concentration. No correlation was found between body weight gain and total protein concentration, yet the glucose concentration significantly influenced the total protein concentration in this group of animals. Among animals which received caffeine, correlations between total protein and glucose concentrations were observed. The analysis did not show that the glucose or total protein concentration significantly influenced the body weight gain of pregnant female rats in the experimental group. The research conducted suggests the possibility of modulating effects of caffeine on adaptive processes during pregnancy.

    The prevalence of obesity is an increasing health problem throughout the world. Maternal pre-pregnancy weight, maternal nutrition and maternal weight gain are among the factors that can cause childhood obesity. Both maternal obesity and excessive weight gain increase the risks of excessive fetal weight gain and high birth weight. Rapid weight gain during fetal period leads to changes in the newborn body composition. Specifically, the increase in body fat ratio in the early periods is associat...

    The steroid 17β-estradiol (E2) modulates energy homeostasis by reducing feeding behavior and increasing energy expenditure primarily through estrogen receptor α (ERα)-mediated mechanisms. Intact ERαKO female mice develop obesity as adults exhibiting decreased energy expenditure and increased fat deposition. However, intact transgenic female mice expressing a DNA-binding-deficient ERα (KIKO) are not obese and have similar energy expenditure, activity and fat deposition as to wild type (WT) females, suggesting that non-estrogen response element (ERE)-mediated signaling is important in E2 regulation of energy homeostasis. Initial reports did not examine the effects of ovariectomy on energy homeostasis or E2's attenuation of post-ovariectomy body weight gain. Therefore, we sought to determine if low physiological doses of E2 (250 ng QOD) known to suppress post-ovariectomy body weight gain in WT females would suppress body weight gain in ovariectomized KIKO females. We observed that the post-ovariectomy increase in body weight was significantly greater in WT females than in KIKO females. Furthermore, E2 did not significantly attenuate the body weight gain in KIKO females as it did in WT females. E2 replacement suppressed food intake and fat accumulation while increasing nighttime oxygen consumption and activity only in WT females. E2 replacement also increased arcuate POMC gene expression in WT females only. These data suggest that in the intact female, ERE-independent mechanisms are sufficient to maintain normal energy homeostasis and to partially restore the normal response to ovariectomy. However, they are not sufficient for E2's suppression of post-ovariectomy body weight gain and its effects on metabolism and activity.

    Full Text Available Abstract Background The purpose of the study was to evaluate the effects of maternal pre-pregnancy body mass index (BMI and gestational weight gain on perinatal outcomes in a population of Korean women. Methods We retrospectively reviewed the medical records of 2,454 women who had received antenatal care at Seoul St. Mary's Hospital from January 2007 to December 2009. We used World Health Organization definitions for Asian populations of underweight (BMI Results Among obese women, the adjusted ORs for gestational diabetes, hypertensive disorder, and incompetent internal os of cervix were 4.46, 2.53, and 3.70 (95% CI = 2.63-7.59, 1.26-5.07, and 1.50-9.12, respectively, and the adjusted ORs for neonatal complications such as macrosomia and low Apgar score were 2.08 and 1.98 (95% CI = 1.34-3.22 and 1.19-3.29, respectively, compared with normal weight women. However, there was no positive linear association between gestational weight gain and obstetric outcomes. In normal weight women, maternal and neonatal complications were significantly increased with inadequate weight gain during pregnancy (p Conclusions This study shows that pre-pregnancy overweight and obesity are more closely related to the adverse obstetric outcomes than excess weight gain during pregnancy. In addition, inadequate weight gain during pregnancy can result in significant complications.

    Objective To evaluate the risk of emergency cesarean section according to the prepregnancy body mass index (BMI) and gestational weight gain per the 2009 Institute of Medicine guidelines. Methods A retrospective analysis of data from 2,765 women with singleton full-term births (2009 to 2012) who attempted a vaginal delivery was conducted. Pregnancies with preeclampsia, chronic hypertension, diabetes, planned cesarean section, placenta previa, or cesarean section due to fetal anomalies or intrauterine growth restriction were excluded. Odds ratios (ORs) and confidence intervals (CIs) for emergency cesarean section were calculated after adjusting for prepregnancy BMI or gestational weight gain. Results Three-hundred and fifty nine (13.0%) women underwent emergency cesarean section. The adjusted OR for overweight, obese, and extremely obese women indicated a significantly increased risk of cesarean delivery. Gestational weight gain by Institute of Medicine guidelines was not associated with an increased risk of cesarean delivery. However, inadequate and excessive weight gain in obese women was highly associated with an increased risk of emergency cesarean section, compared to these in normal BMI (OR, 5.56; 95% CI, 1.36 to 22.72; OR, 3.63; 95% CI, 1.05 to 12.54; respectively), while there was no significant difference between normal BMI and obese women with adequate weight gain. Conclusion Obese women should be provided special advice before and during pregnancy for controlling weight and careful consideration should be needed at the time of vaginal delivery to avoid emergency cesarean section.

    China has one of the highest rates of cesarean sections in the world. However, limited epidemiological studies have evaluated the risk factors for cesarean section among Chinese women. Thus, the aim of this cohort study was to investigate the associations between pre-pregnancy BMI, gestational weight gain (GWG) and the risk of cesarean section in China. A total of 57,891 women with singleton, live-born, term pregnancies were included in this analysis. We found that women who were overweight or obese before pregnancy had an elevated risk of cesarean section. Women with a total GWG above the Institute of Medicine (IOM) recommendations had an adjusted OR for cesarean section of 1.45 (95% CI, 1.40-1.51) compared with women who had GWG within the IOM recommendations. Women with excessive BMI gain during pregnancy also had an increased risk of cesarean section. When stratified by maternal pre-pregnancy BMI, there was a significant association between excessive GWG and increased odds of cesarean section across all pre-pregnancy BMI categories. These results suggest that weight control efforts before and during pregnancy may help to reduce the rate of cesarean sections.

    The aim of this study was to determine the effects of the chronic ingestion of aspartame (ASP) on brain neuropeptide Y (NPY) concentrations, plasma hormones, food intake and body fat. Two groups of male Long-Evans rats, fed on a control (C) well-balanced diet, had to drink either a 0.1% ASP solution or water for a period of 14 weeks starting at weaning. Food intake and body weight were weekly recorded. At the end of the experiment, fat pads were sampled, leptin and insulin were measured in the plasma and NPY in several microdissected brain areas. Substituting ASP for water led to lower body weight (-8%; Pplasma insulin concentrations. Plasma leptin was significantly reduced by 34% (Pcomposition could be related to the decreased effects of NPY on lipid and energy metabolism, independently of insulin. The reasons for the NPY decrease (regulatory or toxicological) are not obvious. The constitutive amino acids of the ASP molecule might participate in the NPY regulation.

    Mice selected for weight gain from 3 to 9 weeks of age on a normal (N) protein diet containing 19.3% protein and a reduced (R) protein diet with 5.1% protein were reared on both diets in generations 7 and 9. The lines NH, NC, NL, RH, RC and RL (H, high; C, control; L, low) were tested for weight gain on diet N and R and for feed intake and feed efficiency on diet N in generation 7. In generation 9, the lines were tested for body composition traits (fat, protein and water percentage) at 3, 6, 9 and 12 weeks of age on both diets. A significant (p < 0.0001) genotype x environment interaction for growth rate was observed in generation 7. Weight gain at both the protein levels was best improved by selection at the protein level itself. Furthermore, the ranking of the lines on diet N was similar for weight gain, feed intake and feed efficiency. In generation 9 at 9 weeks of age, the ranking of the lines for fat percentage was equal to the ranking for weight gain in generation 7 on both test-diets. The association between weight gain and protein or water percentage was less pronounced, particularly on diet R. These results suggest that the largest genetic improvement in growth rate is obtained when the protein content of the feed is the same in selection and production. However, when selection is carried out in one environment while the animals have to perform under conditions with varying nutrient protein contents, selection in an inferior environment may be advantageous.

    Necropsy of gastrointestinal tract of 125 free-range chickens from a subtropical and humid zone of northwestern India revealed four nematode spp. (Ascaridia galli, Heterakis gallinarum, Capillaria spp. and Cheilospirura hamulosa) and four cestode spp. (Raillietina cesticillus, Raillietina echinobothrida, Raillietina tetragona and Amoebotaenia cuneata) The overall prevalence of the helminth parasites was 72.0%. Amongst various helminth species encountered in the region, A. galli emerged out as the most prevalent, followed by H. gallinarum, R. cesticillus and R. echinobothrida. The impact of helminthic infections on body weight gain in growing chickens was investigated. One hundred growing chickens, aged 40 days were randomly assigned to two groups (treated and untreated controls) of 50 birds each. The birds in treated group were given fenbendazole at 7.5 mg per kg body weight in drinking water, while the birds in other group served as untreated controls. At the end of the 90 days of the field trial, the mean body weight gain of untreated controls was 1232.2 ± 7.28 g (13.7 g/day) compared with 1617.6 ± 5.43 g (18.0 g/day) in the treated group. It was associated with a significantly (P < 0.05) higher mean worm burden (32.92 ± 6.12) in untreated controls than the treated group (2.46 ± 1.14). The prevalences of helminthic species and their impact on body weight gain in growing backyard chickens have been discussed.

    Weight gain following renal transplantation occurs frequently but has not been investigated quantitatively. A retrospective chart review of 115 adult renal transplant recipients was used to describe patterns of weight gain during the first 5 years after transplantation. Only 23 subjects (21%) were overweight before their transplant. Sixty-six subjects (57%) experienced a weight gain of greater than or equal to 10%, and 49 subjects (43%) were overweight according to Metropolitan relative weight criteria at 1 year after transplantation. There was an inverse correlation between advancing age and weight gain, with the youngest patients (18-29 years) having a 13.3% weight gain and the oldest patients (age greater than 50 years) having the lowest gain of 8.3% at 1 year (P = 0.047). Black recipients experienced a greater weight gain than whites during the first posttransplant year (14.6% vs. 9.0%; P = 0.043), and maintained or increased this difference over the 5-year period. Men and women experienced comparable weight gain during the first year (9.5% vs. 12.1%), but women continued to gain weight throughout the 5-year study (21.0% total weight gain). The men remained stable after the first year (10.8% total weight gain). Recipients who experienced at least a 10% weight gain also increased their serum cholesterol (mean 261 vs. 219) and triglyceride (mean 277 vs. 159) levels significantly, whereas those without weight gain did not. Weight gain did not correlate with cumulative steroid dose, donor source (living-related versus cadaver), rejection history, pre-existing obesity, the number of months on dialysis before transplantation, or posttransplant renal function. Posttransplant weight gain is related mainly to demographic factors, not to treatment factors associated with the transplant. The average weight gain during the first year after renal transplantation is approximately 10%. This increased weight, coupled with changes in lipid metabolism, may be significant in

    The supplementation of foods with biologically active compounds can be a powerful approach for improving diet and well being. In this study we separately included in pasta matrices a concentrate of γ-conglutin, a glucose-lowering protein from Lupinus albus seeds, an isolate of the other main lupin storage proteins and ovalbumin, at a ratio corresponding to 125 mg of pure protein in 100 g of pasta. With these products we fed rats made hyperglycaemic, for 3 weeks. Among the most relevant changes measured in body and blood parameters were: (i) a significant reduction in food intake of rats fed γ-conglutin concentrate supplemented pasta and a significant limitation in the body weight increase in rats fed α, β and δ-conglutin isolate supplemented pasta, while the food conversion indices were unchanged; (ii) a reduction in glycaemia upon glucose overload trial, especially in the γ-conglutin concentrate supplemented pasta fed animals, at a dose of 45 mg per kg body weight. The correlations among the measured parameters are discussed. Overall, the results evidence the potentiality of supplementing traditional foods with exogenous nutraceutical seed proteins to control body weight gain and glycaemia.

    To evaluate the effects of duck hepatitis virus-1 (DHV-1) on the body weight gain in duck and the effects of silymarin on it in vivo, 100 10-d-old ducks, both male and female, were collected to be subjected to the test. The experiments were conducted in 8 groups: in group 1-3, the animals were inoculated with 1:105 diluted duck hepatitis virus (DHV-1) infected allantoic fluid and given 0, 30, and 50 mg kg-1 BW d-1 silymarin orally, respectively. In group 4-6, the animals were inoculated with 1:5×105 diluted DHV-1 infected allantoie fluid and given 0, 10, and 30 mg kg-1 BW d-1 silymarin orally, respectively. In group 7, the animals were given 10 mg kg-1 BW d-1 silymarin only. Group 8 was the control one treated by injecting sterillized saline into the leg muscles. All the silymarin was given from 0 to 4 d after inoculation of the virus. By the 5th d after inoculation, the vein blood was drawn from the dorsal foot vein and the plasma samples were collected and stored at -20℃. The body weight gain (BWG) was measured from 0 to 10 d after inoculation. The plasma IGF-I, T3, and T4 concentrations were measured by radioimmunoassay (RIA). At the virus dose of 1:5×105 diluted virus infected allantoic fluid, the inoculation of the virus enhanced the BWG significantly compared with that of the control (P< 0.01), while 10-50 mg kg-1 BW d-1 silymarin could counteract the effects of the virus on the BWG dose-dependently. The plasma IGF-I levels showed no correlation with the BWG, but the T3 levels showed a same tropism with the body weight gain. The present results indicated that sublethal DHV-1 enhanced the body weight gain of ducklings significantly, and the silymarin could counteract this effect in vivo.

    Records of individual feed intake (FI) and BW gain (GN) were obtained from the Germ Plasm Evaluation (GPE) program at US Meat Animal Research Center (USMARC). Animals were randomly assigned to pens. Only pens with 6 to 9 steers (n = 289) were used for this study (data set 1). Variance components and genetic parameters were estimated using data set 1. Estimated genetic values (EGV) for FI were calculated by 5 methods using single and 2-trait analyses: 1) individual FI and individual GN, 2) individual FI alone, 3) 2-trait with individual GN but with FI missing, 4) individual GN and pen total FI, and 5) pen total FI alone. Analyses were repeated but with some of the same records assigned artificially to 36 pens of 5 and 4 paternal half sibs per pen (data sets 2 and 3). Models included year as a fixed factor and birth and weaning weights, age on test, and days fed as covariates. Estimates of heritability were 0.42 +/- 0.16 and 0.34 +/- 0.17 for FI and GN. The estimate of the genetic correlation was 0.57 +/- 0.23. Empirical responses to selection were calculated as the average EGV for the top and bottom 10% based on rank for each method but with EGV from method 1 substituted for the EGV on which ranking was based. With data set 1, rank correlations between EGV from method 1 and EGV from methods 2, 3, 4, and 5 were 0.99, 0.53, 0.32, and 0.15, respectively. Empirical responses relative to method 1 agreed with the rank correlations. Accuracy of EGV for method 4 (0.44) was greater than for method 3 (0.35) and for method 5 (0.29). Accuracies for methods 4 and 5 were greater than indicated by empirical responses and correlations with EGV from method 1. Comparisons of the 5 methods were similar for data sets 2 and 3. With data set 2, rank correlations between EGV from method 1 and EGV from methods 3, 4, and 5 were 0.47, 0.64, and 0.62. Average accuracies of 56, 75, and 75% relative to method 1 (0.67) generally agreed with the empirical responses to selection. As expected

    Full Text Available Abstract Background Elevated pregnancy estrogen levels are associated with increased risk of developing breast cancer in mothers. We studied whether pregnancy weight gain that has been linked to high circulating estrogen levels, affects a mother's breast cancer risk. Methods Our cohort consisted of women who were pregnant between 1954–1963 in Helsinki, Finland, 2,089 of which were eligible for the study. Pregnancy data were collected from patient records of maternity centers. 123 subsequent breast cancer cases were identified through a record linkage to the Finnish Cancer Registry, and the mean age at diagnosis was 56 years (range 35 – 74. A sample of 979 women (123 cases, 856 controls from the cohort was linked to the Hospital Inpatient Registry to obtain information on the women's stay in hospitals. Results Mothers in the upper tertile of pregnancy weight gain (>15 kg had a 1.62-fold (95% CI 1.03–2.53 higher breast cancer risk than mothers who gained the recommended amount (the middle tertile, mean: 12.9 kg, range 11–15 kg, after adjusting for mother's age at menarche, age at first birth, age at index pregnancy, parity at the index birth, and body mass index (BMI before the index pregnancy. In a separate nested case-control study (n = 65 cases and 431 controls, adjustment for BMI at the time of breast cancer diagnosis did not modify the findings. Conclusions Our study suggests that high pregnancy weight gain increases later breast cancer risk, independently from body weight at the time of diagnosis.

    Agavins act as a fermentable dietary fiber and have attracted attention due to their potential for reducing the risk of disease. Therefore, we evaluated the effect of supplementation using 10% agavins with a short-degree of polymerization (SDP) from Agave angustifolia Haw. (AASDP) or Agave potatorum Zucc. (APSDP) along with chicory fructans (RSE) as a reference for 5 weeks, on the energy intake, body weight gain, satiety-related hormones from the gut and blood (GLP-1 and ghrelin), blood glucose and lipids, and short-chain fatty acids (SCFAs) from the gut of ad libitum-fed mice. We evaluated the energy intake daily and weight gain every week. At the end of the experiment, portal vein blood samples as well as intestinal segments and the stomach were collected to measure glucagon-like peptide-1 (GLP-1) and ghrelin using RIA and ELISA kits, respectively. Colon SCFAs were measured using gas chromatography. The energy intake, body weight gain, and triglycerides were lower in the fructan-fed mice than in the STD-fed mice. The AASDP, APSDP, and RSE diets increased the serum levels of GLP-1 (40, 93, and 16%, respectively vs. STD) (P ≤ 0.05), whereas ghrelin was decreased (16, 38, and 42%, respectively) (P ≤ 0.05). Butyric acid increased significantly in the APSDP-fed mice (26.59 mmol g(-1), P ≤ 0.001) compared with that in the AASDP- and RSE-fed mice. We concluded that AASDP and APSDP are able to promote the secretion of the peptides involved in appetite regulation, which might help to control obesity and its associated metabolic disorder.

    Full Text Available To explore the joint and independent effects of gestational weight gain (GWG and pre-pregnancy body mass index (BMI on pregnancy outcomes in a population of Chinese Han women and to evaluate pregnant women's adherence to the 2009 Institute of Medicine (IOM gestational weight gain guidelines.This was a multicenter, retrospective cohort study of 48,867 primiparous women from mainland China who had a full-term singleton birth between January 1, 2011 and December 30, 2011. The independent associations of pre-pregnancy BMI, GWG and categories of combined pre-pregnancy BMI and GWG with outcomes of interest were examined using an adjusted multivariate regression model. In addition, women with pre-pregnancy hypertension were excluded from the analysis of the relationship between GWG and delivery of small-for-gestational-age (SGA infants, and women with gestational diabetes (GDM were excluded from the analysis of the relationship between GWG and delivery of large-for-gestational-age (LGA infants.Only 36.8% of the women had a weight gain that was within the recommended range; 25% and 38.2% had weight gains that were below and above the recommended range, respectively. The contribution of GWG to the risk of adverse maternal and fetal outcomes was modest. Women with excessive GWG had an increased likelihood of gestational hypertension (adjusted OR 2.55; 95% CI = 1.92-2.80, postpartum hemorrhage (adjusted OR 1.30; 95% CI = 1.17-1.45, cesarean section (adjusted OR 1.31; 95% CI = 1.18-1.36 and delivery of an LGA infant (adjusted OR 2.1; 95% CI = 1.76-2.26 compared with women with normal weight gain. Conversely, the incidence of GDM (adjusted OR 1.64; 95% CI = 1.20-1.85 and SGA infants (adjusted OR 1.51; 95% CI = 1.32-1.72 was increased in the group of women with inadequate GWG. Moreover, in the obese women, excessive GWG was associated with an apparent increased risk of delivering an LGA infant. In the women who were underweight, poor weight gain was

    Previous studies on group housing of pregnant sows have mainly focused on reproduction, but we hypothesized that the social rank of pregnant sows housed in groups could also affect birth weight, growth, and behavior of their offspring. Therefore, in the present study, pregnant gilts and sows were housed in 15 different groups (n = 7 to 14 animals per group) from 4 d after AI until 1 wk before the expected farrowing date. All groups were fed by an electronically controlled sow feeding system that registered, on a 24-h basis, the time of first visit, number of feeding and non-feeding visits, and number of times succeeding another sow within 2 s. Only in the first 6 groups (n = 57 animals), agonistic interactions were observed continuously. The percentage of agonistic interactions won was highly correlated (r(s) = 0.90, P 50% (n = 62) and low-social ranking (LSR) sows a DS gestation length, litter size, or percentage of live born piglets. During a novel object (NO) test at 3 wk of age, HSR offspring moved and vocalized more than LSR offspring (P Pig breeders that apply group housing for pregnant sows should pay attention to reducing competition around the feeding area, which may reduce aggression among the sows and minimize differences between HSR and LSR sows.

    Full Text Available Short stature, a marker for undernutrition early in life, has been associated with obesity in Brazilian women, but not in men. We tested the hypothesis that weight gain during the reproductive years could explain this gender difference. A national two-stage household survey of mothers with one or more children under five years of age was conducted in Brazil in 1996. The subjects were women aged 20 to 45 years (N = 2297, with last delivery seven months or more prior to the interview. The regions of the country were divided into rural, North/Northeast (urban underdeveloped and South/Southeast/Midwest (urban developed. The dependent variables were current body mass index (BMI measured, BMI prior to childbearing (reported, and BMI change. Socioeconomic variables included mother's years of education and family purchasing power score. A secondary analysis was restricted to primiparous women. The prevalence of current overweight and overweight prior to childbearing (BMI > or = 25 kg/m² was higher among shorter women (<1.50 m compared to normal stature women only in the urban developed region (P < 0.05. After adjustment for socioeconomic variables, age, parity, BMI prior to childbearing, and age at first birth, current BMI was 2.39 units higher (P = 0.008 for short stature women living in the urban developed area compared with short stature women living in the urban underdeveloped area. For both multiparous and primiparous women, BMI gain compared to the value prior to childbearing was significantly higher among short stature women living in the urban developed region (P <= 0.04. These results provide clear evidence that short stature was associated with a higher BMI and with an increased risk of weight gain/retention with pregnancy in the developed areas of Brazil, but not in the underdeveloped ones.

  6. Fetal Programming of Obesity: Maternal Obesity and Excessive Weight Gain

    2014-10-01

    Full Text Available The prevalence of obesity is an increasing health problem throughout the world. Maternal pre-pregnancy weight, maternal nutrition and maternal weight gain are among the factors that can cause childhood obesity. Both maternal obesity and excessive weight gain increase the risks of excessive fetal weight gain and high birth weight. Rapid weight gain during fetal period leads to changes in the newborn body composition. Specifically, the increase in body fat ratio in the early periods is associated with an increased risk of obesity in the later periods. It was reported that over-nutrition during fetal period could cause excessive food intake during postpartum period as a result of metabolic programming. By influencing the fetal metabolism and tissue development, maternal obesity and excessive weight gain change the amounts of nutrients and metabolites that pass to the fetus, thus causing excessive fetal weight gain which in turn increases the risk of obesity. Fetal over-nutrition and excessive weight gain cause permanent metabolic and physiologic changes in developing organs. While mechanisms that affect these organs are not fully understood, it is thought that the changes may occur as a result of the changes in fetal energy metabolism, appetite control, neuroendocrine functions, adipose tissue mass, epigenetic mechanisms and gene expression. In this review article, the effects of maternal body weight and weight gain on fetal development, newborn birth weight and risk of obesity were evaluated, and additionally potential mechanisms that can explain the effects of fetal over-nutrition on the risk of obesity were investigated [TAF Prev Med Bull 2014; 13(5.000: 427-434

    Full Text Available Objectives. To investigate whether lifestyle-only intervention in obese children who maintain or lose a modest amount of weight redistributes parameters of body composition and reverses metabolic abnormalities. Study Design. Clinical, anthropometric, and metabolic parameters were assessed in 111 overweight or obese children (CA of 11.3 ± 2.8 years; 63 females and 48 males, during 8 months of lifestyle intervention. Patients maintained or lost weight (1–5% (group A; n: 72 or gained weight (group B. Results. Group A patients presented with a decrease in systolic blood pressure (SBP and diastolic blood pressure (DBP ( and , resp., BMI (, z-score BMI (, waist circumference (, fat mass (, LDL-C (, Tg/HDL-C ratio (, fasting and postprandial insulin (, and HOMA (, while HDL-C ( and QUICKI increased (. Conversely, group B patients had an increase in BMI (, waist circumference (, SBP (, and in QUICKI (, while fat mass (, fasting insulin (, and HOMA ( decreased. Lean mass, DBP, lipid concentrations, fasting and postprandial glucose, postprandial insulin, and ultrasensitive C-reactive protein (CRP remained stable. Conclusions. Obese children who maintain or lose a modest amount of weight following lifestyle-only intervention tend to redistribute their body fat, decrease blood pressure and lipid levels, and to improve parameters of insulin sensitivity.

    Full Text Available Strain intercross experiments provide a powerful means for mapping genes affecting complex quantitative traits. We report on the genetic variability of the intercross of the Large (LG/J and Small (SM/J inbred mouse strains as a guide to gene mapping studies. Ten SM/J males were crossed to 10 LG/J females, after which animals were randomly mated to produce F1, F2, and F3 intercross generations. The 1632 F3 animals from 200 full-sib families were used to estimate heritabilities and genetic correlations of the traits measured. A subset of families was cross-fostered at birth to allow measurement of the importance of post-natal maternal effects. Data was collected on weekly body weight from one to 10 weeks and on organ weights, body weight, reproductive fat pad weight, and tail length at necropsy in the intercross generations. There was no heterosis for age-specific weights or necropsy traits, except that one-week weight was the highest in the F2 generation, indicating heterosis for maternal effect in the F1 mothers. We found moderate to high heritability for most age-specific weights and necropsy traits. Maternal effects were significant for age-specific weights from one to four weeks but disappeared completely at ten-week weight. Maternal effects for necropsy traits were low and not statistically significant. Age-specific weights showed a typical correlation pattern, with correlation declining as the difference in ages increased. Among necropsy traits, reproductive fat pad and body weights were very highly genetically correlated. Most other genetic correlations were low to moderate. The intercross between SM/J and LG/J inbred mouse strains provides a valuable resource for mapping quantitative trait loci for body size, composition, and morphology

    Full Text Available RATIONALE: Progressive midlife weight gain is associated with multiple adverse health outcomes and may represent an early manifestation of insulin resistance in a distinct subset of women. Emerging data implicate hyperinsulinema as a proximate cause of weight gain and support strategies that attenuate insulin secretion. OBJECTIVE: To assess a previously reported novel hypocaloric carbohydrate modified diet alone (D, and in combination with metformin (M and metformin plus low-dose rosiglitazone (MR, in diverse women with midlife weight gain (defined as >20lbs since the twenties, normal glucose tolerance, and hyperinsulinemia. PARTICIPANTS: 46 women, mean age 46.6±1.0, BMI 30.5±0.04 kg/m2, 54.5% white, 22.7% black, 15.9% Hispanic, at 2 university medical centers. METHODS: A dietary intervention designed to reduce insulin excursions was implemented in 4 weekly nutritional group workshops prior to randomization. MAIN OUTCOME MEASURE: Change in 6-month fasting insulin. Pre-specified secondary outcomes were changes in body weight, HOMA-IR, metabolic syndrome (MS measures, leptin, and adiponectin. RESULTS: Six-month fasting insulin declined significantly in the M group: 12.5 to 8.0 µU/ml, p = .026. Mean 6-month weight decreased significantly and comparably in D, M, and MR groups: 4.7, 5.4, and 5.5% (p's.049, .002, and.032. HOMA-IR decreased in M and MR groups (2.5 to 1.6 and 1.9 to 1.3, p's = .054, .013. Additional improvement in MS measures included reduced waist circumference in D and MR groups and increased HDL in the D and M groups. Notably, mean fasting leptin did not decline in a subset of subjects with weight loss (26.15±2.01 ng/ml to 25.99±2.61 ng/ml, p = .907. Adiponectin increased significantly in the MR group (11.1±1.0 to 18.5±7.4, p<.001 Study medications were well tolerated. CONCLUSIONS: These findings suggest that EMPOWIR's easily implemented dietary interventions, alone and in combination with pharmacotherapies that

    Introduction of a new group of antipsychotic drugs, called atypical because of the proprieties differing them from classical neuroleptics, gave hope for the beginning of a new era in treatment of psychoses, including schizophrenia. Different mechanisms of action not only resulted in a broader spectrum of action and high efficacy but also in a relative lack of extrapiramidal symptoms. However, atypical neuroleptics are not totally free from adverse effects. Symptoms such as sedation, metabolic changes and weight gain, often very quick and severe - present also in the case of classical drugs, but put to the background by extrapiramidal symptoms--have become prominent. Weight gain is important both from the clinical and subjective point of view--as associated with serious somatic consequences and as a source of enormous mental distress. These problems are addressed in this review, with the focus on weight gain associated with the use of specific atypical neuroleptics.

    Benzylamine is found in Moringa oleifera, a plant used to treat diabetes in traditional medicine. In mammals, benzylamine is metabolized by semicarbazide-sensitive amine oxidase (SSAO) to benzaldehyde and hydrogen peroxide. This latter product has insulin-mimicking action, and is involved in the effects of benzylamine on human adipocytes: stimulation of glucose transport and inhibition of lipolysis. This study examined whether chronic, oral administration of benzylamine could improve glucose tolerance and the circulating lipid profile without increasing oxidative stress in overweight and pre-diabetic mice. The benzylamine diffusion across the intestine was verified using everted gut sacs. Then, glucose handling and metabolic markers were measured in mice rendered insulin-resistant when fed a high-fat diet (HFD) and receiving or not benzylamine in their drinking water (3600micromol/(kgday)) for 17 weeks. HFD-benzylamine mice showed lower body weight gain, fasting blood glucose, total plasma cholesterol and hyperglycaemic response to glucose load when compared to HFD control. In adipocytes, insulin-induced activation of glucose transport and inhibition of lipolysis remained unchanged. In aorta, benzylamine treatment partially restored the nitrite levels that were reduced by HFD. In liver, lipid peroxidation markers were reduced. Resistin and uric acid, surrogate plasma markers of metabolic syndrome, were decreased. In spite of the putative deleterious nature of the hydrogen peroxide generated during amine oxidation, and in agreement with its in vitro insulin-like actions found on adipocytes, the SSAO-substrate benzylamine could be considered as a potential oral agent to treat metabolic syndrome.

    The number of Americans who are overweight or obese has reached epidemic proportions. Elevated weight is associated with health problems and increased medical expenditures. This paper analyzes Waves 1 and 2 of the National Epidemiological Survey of Alcohol and Related Conditions to investigate the role of alcohol consumption in weight gain. Alcohol is not only an addictive substance but also a high-calorie beverage that can interfere with metabolic function and cognitive processes. Because men and women differ in the type and amount of alcohol they consume, in the biological effects they experience as a result of alcohol consumption, and in the consequences they face as a result of obesity, we expect our results to differ by gender. We use first-difference models of body mass index (BMI) and alcohol consumption (frequency and intensity) to control for time-invariant unobservable factors that may influence changes in both alcohol use and weight status. Increasing frequency and intensity of alcohol use is associated with statistically significant yet quantitatively small weight gain for men but not for women. Moreover, the first-difference results are much smaller in magnitude and sometimes different in sign compared with the benchmark pooled cross-sectional estimates.

    Identifying subjects at high risk of weight gain according to consumption of food groups is important for individualizing nutritional education, but prospective studies of this issue have been few. We determined whether intake of specific food groups could predict future weight gain. We evaluated data from health checkups on 1236 Japanese men aged 28 to 87 years in 2005 and 2006. Dietary intake was assessed by a 24-h dietary recall at baseline. Weight change was measured after 1 year. Weight increased in 44.7% (n = 553) of participants. Multivariate regression analysis involving many food groups showed a significant association between sugar intake and weight gain after adjustment for age, body mass index (BMI), total energy intake, alcohol, smoking and regular physical exercise (β = 0.22, P = 0.04). The effect of intake of 'fats and oils' was significant when adjusted for age and BMI, however, it became insignificant after adjustment for age, BMI and total energy intake. Intake of sugar, which was evaluated as a food group, was predictive of subsequent weight gain among Japanese men, even after adjustment for many confounders. This corroborates the evidence so far concerning the links between sugar intake and weight gain. Further long-term research is required to give robust recommendation to the public.

  17. Do low-calorie sweeteners promote weight gain in rodents?

    Glendinning, John I

    2016-10-01

    Low-calorie sweeteners (LCSs) are used globally to increase the palatability of foods and beverages, without the calories of sugar. Recently, however, there have been claims that LCSs promote obesity. Here, I review the literature linking LCS consumption to elevated body weight in rodents. A recent systematic review found when the LCSs were presented in water or chow, only a minority of the studies reported elevated weight gain. In contrast, when the LCSs were presented in yogurt, the majority of the studies reported elevated weight gain. This review focuses on this latter subset of studies, and asks why the combination of LCSs and yogurt promoted weight gain. First, LCSs have been hypothesized to induce metabolic derangement because they uncouple sweet taste and calories. However, the available evidence indicates that the LCS-treated yogurts did not actually taste sweet to rats in the published studies. Without a sweet taste, the concerns about uncoupling sweet taste and calories would not be relevant. Second, in several studies, the LCS-treated yogurt increased weight gain without increasing caloric intake. This indicates that caloric intake alone cannot explain the elevated weight gain. Third, there is evidence that LCSs and yogurt can each alter the gut microbiota of rodents. Given recent work indicating that changes in gut microbiota can modulate body weight, it is possible that the combination of LCS and yogurt alters the gut microbiota in ways that promote weight gain. While this hypothesis remains speculative, it is consistent with the observed rodent data. In human studies, LCSs are usually presented in beverages. Based on the rodent work, it might be worthwhile to evaluate the impact of LCS-treated yogurt in humans.

    Full Text Available Abstract Background More people than ever are considered obese and the resulting health problems are evident. These facts highlight the need for identification of critical time periods for weight gain. Therefore the purpose was to assess potential changes that occur in body weight during the Thanksgiving holiday break in college students. Methods 94 college students (23.0 ± 4.6 yrs, 72.1 ± 14.0 kg, 172.6 ± 9.3 cm, 24.0 ± 3.9 kg/m2 reported to the human body composition laboratory at the University of Oklahoma following a 6-hour fast with testing occurring prior to, and immediately following the Thanksgiving holiday break (13 ± 3 days. Body weight (BW was assessed using a balance beam scale while participants were dressed in minimal clothing. Paired t-tests were used to assess changes in BW pre and post Thanksgiving holiday with additional analysis by gender, body mass index (BMI, and class standing (i.e. undergraduate vs. graduate. Results Overall, a significant (P P P 2 group compared to a non significant 0.2 kg gain in the normal group (2. Conclusion These data indicate that participants in our study gained a significant amount of BW (0.5 kg during the Thanksgiving holiday. While an increase in BW of half a kilogram may not be cause for alarm, the increase could have potential long-term health consequences if participants retained this weight gain throughout the college year. Additionally, because the overweight/obese participants gained the greatest amount of BW, this group may be at increased risk for weight gain and further obesity development during the holiday season.

    This research encompasses a community sample of 497 women in peri- and post-menopause and uses structural equation modelling to investigate the structural models of weight variation and weight gain. Variables such as body shape concerns, depression, stress and life events are explored. Weight gain (from pre-menopause to current menopausal status) was observed in 69 per cent of participants. The predictors of weight gain were lower education level (β = -.146, p = .017), less or no physical exercise (β = -.111, p = .021), having a recent psychological problem (β = .191, p post-menopause (β = .147, p = .013) and more frequent body shape concerns (β = .313, p menopause is recommended; risk groups should be targeted considering the predictors of weight increase.

    The mechanisms behind weight gain following deep brain stimulation (DBS) surgery seem to be multifactorial and suspected depending on the target, either the subthalamic nucleus (STN) or the globus pallidus internus (GPi). Decreased energy expenditure following motor improvement and behavioral and/or metabolic changes are possible explanations. Focusing on GPi target, our objective was to analyze correlations between changes in brain metabolism (measured with PET) and weight gain following GPi-DBS in patients with Parkinson's disease (PD). Body mass index was calculated and brain activity prospectively measured using 2-deoxy-2[18F]fluoro-D-glucose PET four months before and four months after the start of GPi-DBS in 19 PD patients. Dopaminergic medication was included in the analysis to control for its possible influence on brain metabolism. Body mass index increased significantly by 0.66 ± 1.3 kg/m2 (p = 0.040). There were correlations between weight gain and changes in brain metabolism in premotor areas, including the left and right superior gyri (Brodmann area, BA 6), left superior gyrus (BA 8), the dorsolateral prefrontal cortex (right middle gyrus, BAs 9 and 46), and the left and right somatosensory association cortices (BA 7). However, we found no correlation between weight gain and metabolic changes in limbic and associative areas. Additionally, there was a trend toward a correlation between reduced dyskinesia and weight gain (r = 0.428, p = 0.067). These findings suggest that, unlike STN-DBS, motor improvement is the major contributing factor for weight gain following GPi-DBS PD, confirming the motor selectivity of this target.

    Full Text Available Objective: Proper nutrition during pregnancy is essential for optimal fetal growth. Investigation of the relation between pregnancy weight gain and birth weight in rural regions of Rasht, center of Guilan Province in Iran, was the purpose of this study. Methods: In this cohort study, prenatal data of 918 women who attended local health centers with singleton term pregnancies were recorded. Maternal demographic characteristics, anthropometric measurements, total pregnancy weight gain and birth weight were recorded by health workers. The women were stratified based on their pre-pregnancy body mass index (BMI into four groups: underweight women, women with normal weight, overweight women and obese women. The relation between weight gain and low birth weight (LBW, birth weight <2500 g and macrosomia (birth weight >4000 g was studied in these four groups. Data were analyzed using Chi-square test, independent t-test, Pearson correlation and logistic regression with 95% confidence intervals. Findings: More than 50% of underweight women and women with normal weight and almost 30% of overweight and obese women gained weight less than what is mentioned in the Institute of Medicine (IOM recommendations. The incidence rate of LBW was 7.1% and that of macrosomia was 5%. Mean weight gain of women with LBW was significantly less than mean weight gain of women who had an infant with a birth weight more than 2500 g (P=0.002. Women who gained weight less than the recommended range had higher rate of LBW in their infants (P=0.01 and the incidence of macrosomia in women with a weight gain above the recommended weight was higher than that in others (P=0.012. Pregnancy weight gain less than what is mentioned in the IOM guideline was the only predictor for LBW (OR=2.79, CI=1.16-6.73, P=0.02. Conclusion:Pregnancy weight gains less than what is mentioned in the IOM recommendation was a significant predictor of LBW, regardless of pre-pregnancy BMI.

Laparotomized rats (n=18 were randomly divided into three equal groups. Normal saline was administered to the rats of group 1 (control. Tramadol (dosed at 10 mg/kg bwt was administered singly to the rats of group 2. The same dose of tramadol was administered repeatedly every 12 h up to 72 h to the rats of group 3. On day 3 and 10 post-laparotomy (PSL, blood urea nitrogen, serum creatinine, total serum protein, hematocrit, hemoglobin concentration and red blood cell counts in the rats of group 2 were found to be significantly (P<0.05 higher than those obtained in group 1 and group 3. Mean weights of rats in group 1 and group 3 were significantly lower than those of the rats of group 2 PSL. This study showed that repeated tramadol administration lead to slower weight gain as well as marked decrease in biochemical and erythrocytic variables in rats. Therefore, single administration of tramadol PSL may suffice for analgesia. [J Adv Vet Anim Res 2015; 2(3.000: 316-320

    Full Text Available Rice koji is considered a readily accessible functional food that may have health-promoting effects. We investigated whether white, yellow, and red koji have the anti-obesity effect in C57BL/6J mice fed a high-fat diet (HFD, which is a model for obesity. Mice were fed HFD containing 10% (w/w of rice koji powder or steamed rice for 4 weeks. Weight gain, epididymal white adipose tissue, and total adipose tissue weight were significantly lower in all rice koji groups than in the HFD-rice group after 4 weeks. Feed efficiency was significantly reduced in the yellow koji group. Blood glucose levels were significantly lower in the white and red koji groups with HOMA-R and leptin levels being reduced in the white koji group. White and red koji increased glucose uptake and GLUT4 protein expression in L6 myotube cells. These results showed that all rice koji have the anti-obesity or anti-diabetes effects although the mechanisms may differ depending on the type of rice koji consumed.

    2008-01-01

    Context Soft drink consumption in the United States has tripled in recent decades, paralleling the dramatic increases in obesity prevalence. The purpose of this clinical review is to evaluate the extent to which current scientific evidence supports a causal link between sugar-sweetened soft drink consumption and weight gain. Evidence acquisition MEDLINE search of articles published in all languages between 1966 and December 2006 containing key words or medical subheadings, such as “soft drinks” and “weight.” Additional articles were obtained by reviewing references of retrieved articles, including a recent systematic review. All reports with cross-sectional, prospective cohort, or clinical trial data in humans were considered. Evidence synthesis Six of 15 cross-sectional and 6 of 10 prospective cohort studies identified statistically significant associations between soft drink consumption and increased body weight. There were 5 clinical trials; the two that involved adolescents indicated that efforts to reduce sugar-sweetened soft drinks slowed weight gain. In adults, 3 small experimental studies suggested that consumption of sugar-sweetened soft drinks caused weight gain; however, no trial in adults was longer than 10 weeks or included more than 41 participants. No trial reported the effects on lipids. Conclusions Although observational studies support the hypothesis that sugar-sweetened soft drinks cause weight gain, a paucity of hypothesis-confirming clinical trial data has left the issue open to debate. Given the magnitude of the public health concern, larger and longer intervention trials should be considered to clarify the specific effects of sugar-sweetened soft drinks on body weight and other cardiovascular risk factors.

    Dietary fibre (DF) obtained from Agave tequilana, which is rich in fructans and insoluble DF, and jamaica calyces (Hibiscus sabdariffa), which is rich in DF and phenolic compounds, were assessed as new potential functional ingredients using the hypercholesterolemic animal model. Wistar rats (200-250 g) were divided into 3 groups (n=8) and fed with cholesterol-rich diets supplemented with cellulose (CC, control), agave DF (ADF) or ADF with jamaica calyces (ADF-JC). After consuming the test diets for 5 weeks, weight gain in the ADF-JC group was significantly lower than in the other groups. The ADF and ADF-JC groups had a reduced concentration of cholesterol transporters in the caecum tissue, although no changes were observed in the plasma lipid profile. Both treatments improved the redox status by reducing the malondialdehyde serum levels and protein oxidative damage, compared to the CC group. DF from A. tequilana alone, or in combination with jamaica calyces, shows promising potential as a bioactive ingredient.

    Previous studies reported that the co-injection of leptin and cannabinoid CB1 receptor antagonists reduces food intake and body weight in rats, and this effect is more profound than that induced by these compounds individually. Additionally, serotonin mediates the effects of numerous anorectic drugs. To investigate whether serotonin interacts with leptin and endocannabinoids to affect food intake and body weight, we administered 5-hydroxytryptamine(HT)1B and 5-hydroxytryptamine(HT)2C serotonin receptor antagonists (3 mg/kg GR 127935 and 0.5 mg/kg SB 242084, respectively) to male Wistar rats treated simultaneously with leptin (100 μg/kg) and the CB1 receptor inverse agonist AM 251 (1 mg/kg) for 3 days. In accordance with previous findings, the co-injection of leptin and AM 251, but not the individual injection of each drug, resulted in a significant decrease in food intake and body weight gain. Blockade of the 5-HT1B and 5-HT2C receptors completely abolished the leptin- and AM 251-induced anorectic and body-weight-reducing effects. These results suggest that serotonin mediates the leptin- and AM 251-dependent regulation of feeding behavior in rats via the 5-HT1B and 5-HT2C receptors.

    Full Text Available Objective: to estimate the role of adipose tissue in gestational weight gain (GWG and preferential fat deposition among normal-weight women. Subjects and methods: prospective cohort study of 84 pregnancies: maternal body mass index 18,5–24,9 kg/m2, singleton term pregnancy, nondiabetic women, somatically well. GWG and skinfold thickness were evaluated in the 1st, 2nd, 3d trimesters, on the 3d day after delivery. Results: fat mass gain in low GWG was similar to recommended GWG and in the high-GWG group was greater one. Women with recommended and low GWG returned to their initial fat level on the 3d day after delivery, in excessive weight gain fat significantly increased (р=0,025. Compared to initial recommended GWG resulted in triceps skinfold thicknesses loss (р=0,001, in abdominal skinfold gained nothing and in thighs skinfold thicknesses increasing (р=0,021. Inadequate GWG leads to fat loss in arms (р=0,017, fat of abdominal area and thighs return to initial level. In excessive GWG fat in the upper trunk and arms not changed, in the lower area (thighs significantly increased compared to initial level (р=0,001 or other groups (р=0,001. Conclusion: excessive GWG was associated with greater adipose tissue cumulation and its deposition preferentially over the thighs. Inadequate GWG was clearly linked to low fat-free mass gain.

    BACKGROUND/OBJECTIVES: Physiological evidence indicates that high-protein diets reduce caloric intake and increase thermogenic response, which may prevent weight gain and regain after weight loss. Clinical trials have shown such effects, whereas observational cohort studies suggest an association...... between greater protein intake and weight gain. In both types of studies the results are based on average weight changes, and show considerable diversity in both directions. This study investigates whether the discrepancy in the evidence could be due to recruitment of overweight and obese individuals......, and body characteristics. Different subsets of the DCH-participants, comparable with the trial participants, were analyzed for weight maintenance according to the randomization status (high or low protein) of the matched trial participants. RESULTS: Trial participants were generally heavier, had larger...

    We examine the impact of Axis II personality disorders (PDs) on body weight. PDs are psychiatric conditions that develop early in life from a mixture of genetics and environment, are persistent, and lead to substantial dysfunction for the affected individual. The defining characteristics of PDs conceptually link them with body weight, but the direction of the relationship likely varies across PD type. To investigate these links, we analyze data from Wave II of the National Epidemiological Survey of Alcohol and Related Conditions. We measure body weight with the body mass index (BMI) and a dichotomous indicator for obesity (BMI≥30). We find that women with PDs have significantly higher BMI and are more likely to be obese than otherwise similar women. We find few statistically significant or economically meaningful effects for men. Paranoid, schizotypal, and avoidant PDs demonstrate the strongest adverse impacts on women's body weight while dependent PD may be protective against elevated body weight among men. Findings from unconditional quantile regressions demonstrate a positive gradient between PDs and BMI in that the effects are greater for higher BMI respondents.

    Full Text Available The present study was conducted to determine some environmental factors affecting birth weight, weaning weight and daily live weight gain of Holstein calves of a livestock facility in Izmir, Turkey. The data on 2091 calves born between the years 2005-2010 were used to assess the relevant parameters. Effects of calving year, calving month, calf gender and the interaction between calving year and calving month on calves’ birth weights were highly significant. The overall mean of birth weights was 39.6±0.15 kg. In addition, effects of calving year, calving month, gender, birth weight, weaning age, calving year x calving month, calving year x gender and calving year x calving month x gender interactions on weaning weight (WW and daily live weight gain (DLWG were highly significant. The overall means of WW and DLWG were respectively found to be 79.7±0.20 kg and 525±2.5 g. A one kilogram increase in birth weight resulted in an increase of 0.89 kg in weaning weight and a decrease of 1.26 g in daily live weight gain. Prenatal temperature-humidity index (THI affected birth weight of calves (R2=0.67. Increasing THI from 50 to 80 resulted in 3.8 kg decrease in birth weight.

    BACKGROUND: According to Karasek's Demand/Control Model, workload can be conceptualized as job strain, a combination of psychological job demands and control in the job. High job strain may result from high job demands combined with low job control. Aim To give an overview of the literature...... on the association between obesity and psychological workload. METHOD: We carried out a review of the associations between psychological workload and body weight in men and women. In total, 10 cross-sectional studies were identified. RESULTS: The review showed little evidence of a general association between...... psychological workload and body mass index. Only weak positive associations were found, and only between elements of psychological workload and overall body weight. For body fat distribution, two out of three studies showed a positive association in men, but the associations became insignificant after...

  18. Ablation of TRPM5 in Mice Results in Reduced Body Weight Gain and Improved Glucose Tolerance and Protects from Excessive Consumption of Sweet Palatable Food when Fed High Caloric Diets.

    Full Text Available The calcium activated cation channel transient receptor potential channel type M5 (TRPM5 is part of the downstream machinery of the taste receptors and have been shown to play a central role in taste signalling. In addition it is also found in other types of chemosensory cells in various parts of the body as well as in pancreatic β-cells. The aim of this study was to investigate the effects of TRPM5 gene ablation on body weight, insulin sensitivity and other metabolic parameters in long-term high caloric diet induced obesity. Trpm5-/- mice gained significantly less body weight and fat mass on both palatable carbohydrate and fat rich cafeteria diet and 60% high fat diet (HFD and developed less insulin resistance compared to wild type mice. A main finding was the clearly improved glucose tolerance in Trpm5-/- mice compared to wild type mice on cafeteria diet, which was independent of body weight. In addition, it was shown that Trpm5-/- mice consumed the same amount of calories when fed a HFD only or a HFD in combination with a palatable chocolate ball, which is in contrast to wild type mice that increased their caloric intake when fed the combination, mainly due to excessive consumption of the chocolate ball. Thus the palatable sugar containing diet induced overeating was prevented in Trpm5-/- mice. This indicates that sweet taste induced overeating may be a cause for the increased energy intake and glucose intolerance development seen for wild type mice on a sugar and high fat rich cafeteria diet compared to when on a high fat diet. This study point to an important role for the taste signalling system and TRPM5 in diet induced glucose intolerance.

    Maarten Bak

    Full Text Available INTRODUCTION: Antipsychotics (AP induce weight gain. However, reviews and meta-analyses generally are restricted to second generation antipsychotics (SGA and do not stratify for duration of AP use. It is hypothesised that patients gain more weight if duration of AP use is longer. METHOD: A meta-analysis was conducted of clinical trials of AP that reported weight change. Outcome measures were body weight change, change in BMI and clinically relevant weight change (7% weight gain or loss. Duration of AP-use was stratified as follows: ≤6 weeks, 6-16 weeks, 16-38 weeks and >38 weeks. Forest plots stratified by AP as well as by duration of use were generated and results were summarised in figures. RESULTS: 307 articles met inclusion criteria. The majority were AP switch studies. Almost all AP showed a degree of weight gain after prolonged use, except for amisulpride, aripiprazole and ziprasidone, for which prolonged exposure resulted in negligible weight change. The level of weight gain per AP varied from discrete to severe. Contrary to expectations, switch of AP did not result in weight loss for amisulpride, aripiprazole or ziprasidone. In AP-naive patients, weight gain was much more pronounced for all AP. CONCLUSION: Given prolonged exposure, virtually all AP are associated with weight gain. The rational of switching AP to achieve weight reduction may be overrated. In AP-naive patients, weight gain is more pronounced.

    The prevalence of overweight and obesity among adolescents is rising rapidly in many countries, including Malaysia. This article aims to present the associations between body mass index-based body weight status, body weight perception, and weight control practices among adolescents in Malaysia. The Malaysia School Based Nutrition Survey 2012, which included a body weight perception questionnaire and anthropometric measurements, was conducted on a representative sample of 40 011 students from Standard 4 until Form 5, with a 90.5% response rate. Comparing actual and perceived body weight status, the findings show that 13.8% of adolescents underestimated their weight, 35.0% overestimated, and 51.2% correctly judged their own weight. Significantly more normal weight girls felt they were overweight, whereas significantly more overweight boys perceived themselves as underweight. The overall appropriateness of weight control practices to body weight was 72.6%. Adolescents attempting to lose or gain weight need to have better understanding toward desirable behavioral changes.

  4. Muscle Mass and Weight Gain Nutritional Supplements

    Science.gov (United States)

    Campbell, Bill

    There are numerous sports supplements available that claim to increase lean body mass. However, for these sports supplements to exert any favorable changes in lean body mass, they must influence those factors regulating skeletal muscle hypertrophy (i.e., satellite cell activity, gene transcription, protein translation). If a given sports supplement does favorably influence one of these regulatory factors, the result is a positive net protein balance (in which protein synthesis exceeds protein breakdown). Sports supplement categories aimed at eliciting a positive net protein balance include anabolic hormone enhancers, nutrient timing pre- and postexercise workout supplements, anticatabolic supplements, and nitric oxide boosters. Of all the sports supplements available, only a few have been subject to multiple clinical trials with repeated favorable outcomes relative to increasing lean body mass. This chapter focuses on these supplements and others that have a sound theoretical rationale in relation to increasing lean body mass.

    Full Text Available A meta-analysis was made of data from a total of 211 growing-finishing Iberian (IB pigs from four separate and independent sets of trials. Within each set of trials, a factorial arrangement of treatments was used, involving several concentrations of ideal protein in the diets and two or three levels of feed intake. Pigs were slaughtered at several stages of growth from 10 to 150 kg body weight (BW. The partition of dietary protein in the body of the pigs, the empty-body gain (EBG, the chemical composition of EBG, growth of primal cuts in the cold eviscerated carcass (without head, feet, and tail, and mass of dissected tissues in trimmed shoulder and ham were determined. Linear regression equations allowed estimating N requirements for maintenance as 175 mg/(kg BW0.75 · kg dry-matter intake · d-1 and an average value for the net efficiency of utilization of the dietary protein apparently absorbed of 0.386. In pigs offered adequate protein to energy diets, EBG was predicted as a function of average BW and feeding level (p<0.001. Multiple regression equations were constructed, which derived nutrient (g kg-1 or energy (MJ kg-1 composition of EBG as a function of empty-body weight (EBW, dietary protein to energy ratio, and level of feeding (p<0.001. These predictive equations, not applicable to pigs of lean and conventional genotypes, can contribute to the design of optimal feeding strategies to improve the efficiency of IB pig production systems and to achieve high quality standards in end products for the market.

    One in four Canadian adults is obese, and more women are entering pregnancy with a higher body mass index (BMI) than in the past. Pregnant women who are overweight or obese have a higher risk of pregnancy-related complications than women of normal weight. Gestational weight gain (GWG) is also associated with childhood obesity. Although the factors influencing weight gain during pregnancy are multifaceted, little is known about the social inequality of GWG. This review will address some of the socioeconomic factors and maternal characteristics influencing weight gain and the impact that excessive GWG has on health outcomes such as post-partum weight retention. The effects of an overweight or obese pre-pregnancy BMI on GWG and neonatal outcomes will also be addressed. The timing of weight gain is also important, as recommendations now include trimester-specific guidelines. While not conclusive, preliminary evidence suggests that excessive weight gain during the first trimester is most detrimental.

    Body weight changes occur during the clinical course of Parkinson's disease (PD) and with surgical treatment, but the effect of dopaminergic treatment on weight is unknown. Body mass index (BMI), Hamilton depression scale score (HDS), and Unified Parkinson's Disease Rating Scale III (UPRS-III) were measured before and 3 months after starting pramipexole in 28 PD patients. Pramipexole produced a significant weight increase, as well as motor and mood improvement (P weight gain in PD.

Utilizaram-se 26 animais machos não-castrados, com peso vivo (PV médio inicial de 15 kg e 7 a 8 meses de idade, alimentados com dieta contendo 2,6 Mcal de energia metabolizável. Ao início do experimento, seis animais foram abatidos e serviram como referência para estimativa da composição corporal e do peso de corpo vazio (PCVZ iniciais. Posteriormente, formaram-se grupos homogêneos de quatro animais, distribuídos ao acaso em dois programas de alimentação (tratamentos: alimentação à vontade (AV; e restrição alimentar de 85, 70 e 55% do consumido pelo grupo com alimentação à vontade. Os animais com AV foram abatidos no momento em que o PV se aproximou de 25 kg. As equações do logaritmo (log dos conteúdos corporais de proteína (CCP foram ajustadas considerando o log do PCVZ. Derivando-se essa equação, obteve-se a equação de predição do conteúdo de proteína por kg de ganho de PCVZ. Os conteúdos protéicos dos animais experimentais mantiveram-se praticamente constantes e variaram de 205,60 para 201,69 g/kg de PCVZ (redução de 1,9% e de 15 para 25 kg com o aumento do PV.

    This study examined weight trajectories in obese patients with binge eating disorder (BED) during the year prior to treatment initiation and explored potential correlates of these weight changes. One hundred thirty (N=130) consecutive, treatment-seeking, obese patients with BED were assessed with structured interviews and self-report questionnaires. Eighty-three percent (83%; n=108) of treatment seeking obese BED patients gained weight, and 65% (n=84) gained a clinically significant amount of weight (greater than or equal to 5% body weight), in the year preceding treatment. Overall, participants reported a mean percent weight gain of 8% (16.6 pounds) during the 12months prior to treatment with a wide range of weight changes across participants (from a 52% weight gain to a 13% weight loss). A substantial proportion of patients (35%), categorized as High Weight Gainers (defined as gaining more than 10% of body weight during previous year), reported gaining an average of 16.7% of body weight. Low Weight Gainers (defined as gaining greater than 5%, but less than 10%) comprised 29% of the sample and were characterized by a mean gain of 6.9% of body weight. Weight Maintainers/Losers (defined as having maintained or lost weight during the 12months prior to treatment) comprised 17% of the sample and reported losing on average 2.8% of body weight. These three groups did not differ significantly in their current weight and eating behaviors or eating disorder psychopathology. The majority of treatment-seeking obese patients with BED reported having gained substantial amounts of weight during the previous year. These findings provide an important context for interpreting the modest weight losses typically reported in treatment studies of BED. Failure to produce weight loss in these studies may be reinterpreted as stabilization of weight and prevention of further weight gain.

This is a retrospective study, developed in a health center in the municipality of São Paulo, with data obtained from medical records. Linear regression analysis was carried out. An association was verified between the initial and final nutritional status (ppregnancy underweight was higher compared those who started overweight/obese (p=0.005). Weight gain was insufficient for 43.4% of the pregnant women with adequate initial weight and for 36.4% of all the pregnant women studied. However, 37.1% of those who began the pregnancy overweight/obese finished with excessive weight gain, a condition that ultimately affected almost a quarter of the pregnant women. Anemia and low birth weight were uncommon, however, in the linear regression analysis, birth weight was associated with weight gain (pnutritional care before and during pregnancy to promote maternal-infant health.

    The involvement of the gut microbiota on weight-gain and its relationship with childhood undernutrition and growth has been reported. Thus, the gut microbiota constitutes a potential therapeutic target for preventing growth impairment. However, our knowledge in this area is limited. In this study we aimed at evaluating the relationship among early microbiota, growth, and development in preterm infants. To this end we assessed the levels of specific microorganisms by qPCR, and those of short chain fatty acids by mean of gas-chromatography, in feces from 63 preterm newborns and determined their weight-gain during the first months. The statistical analyses performed indicate an influence of the intestinal microbiota in weight-gain, with the levels of some microorganisms showing a significant association with the weight-gain of the infant. The levels of specific microbial groups during the first days of life were found to affect weight gain by the age of 1 month. Moreover, clustering of the infants on the basis of the microbiota composition at 1 month of age rendered groups which showed differences in weight z-scores. Our results suggest an association between the gut microbiota composition and weight-gain in preterm infants at early life and point out potential microbial targets for favoring growth and maturation in these infants.

    Full Text Available Introduction: Abnormal weight gain during pregnancy may exert a negative effect on the development of the foetus, the course of pregnancy, and later the state of health of the mother and her baby. Due to the unfavourable health consequences of abnormal body weight gains in expectant mothers studies of the factors that determine the amount of these gains are important. Aim of the research : Evaluation of the relationship between health behaviours in pregnancy, nutritional status before pregnancy, selected socio-demographic factors, and gestational weight gain. Material and methods : The investigation included 274 women. Using a questionnaire, information was collected pertaining to the place of residence, age, body height and weight, cigarette smoking, and eating habits during pregnancy. The total weight gain during pregnancy was calculated as the difference between perinatal weight and pre-pregnancy body weight. Gestational weight gains were classified as low, recommended, or high. Results: Increased risk of high weight gain was associated with the consumption of alcoholic beverages (odds ratio (OR = 2.82, especially beer (OR = 2.72, high consumption of products supplying proteins of animal origin (OR = 2.87, and overweight before pregnancy (OR = 3.37, as well as the delivery being the mother’s first, compared to the third and subsequent childbirth (OR = 4.17. Conclusions: This study indicates that there is a need for health education among females at reproductive age in order to reduce excess weight before conception, and promotion of adequate health behaviours in pregnancy, which would allow the maintenance of normal weight gain during this period.

    Dopamine agonists have been implicated in causing compulsive behaviors in patients with Parkinson's disease (PD). These have included gambling, hypersexuality, hobbyism, and other repetitive, purposeless behaviors ("punding"). In this report, we describe 7 patients in whom compulsive eating developed in the context of pramipexole use. All of the affected patients had significant, undesired weight gain; 4 had other comorbid compulsive behaviors. In the 5 patients who lowered the dose of pramipexole or discontinued dopamine agonist treatment, the behavior remitted and no further weight gain occurred. Physicians should be aware that compulsive eating resulting in significant weight gain may occur in PD as a side-effect of dopamine agonist medications such as pramipexole. Given the known risks of the associated weight gain and obesity, further investigation is warranted.

    The mechanisms behind weight gain following deep brain stimulation (DBS) surgery seem to be multifactorial and suspected depending on the target, either the subthalamic nucleus (STN) or the globus pallidus internus (GPi). Decreased energy expenditure following motor improvement and behavioral and/or metabolic changes are possible explanations. Focusing on GPi target, our objective was to analyze correlations between changes in brain metabolism (measured with PET) and weight gain following GPi...

    Objective To investigate the association between weekly weight gain, during the second and third trimesters, classified according to the 2009 Institute of Medicine (IOM/NRC) recommendations, and maternal and fetal outcomes. Methods Gestational weight gain was evaluated in 2,244 pregnant women of the Brazilian Study of Gestational Diabetes (Estudo Brasileiro do Diabetes Gestacional – EBDG). Outcomes were cesarean delivery, preterm birth and small or large for gestational age birth (SGA, LGA). Associations between inadequate weight gain and outcomes were estimated using robust Poisson regression adjusting for pre-pregnancy body mass index, trimester-specific weight gain, age, height, skin color, parity, education, smoking, alcohol consumption, gestational diabetes and hypertensive disorders in pregnancy. Results In fully adjusted models, in the second trimester, insufficient weight gain was associated with SGA (relative risk [RR] 1.72, 95% confidence interval [CI] 1.26–2.33), and excessive weight gain with LGA (RR 1.64, 95% CI 1.16–2.31); in third trimester, excessive weight gain with preterm birth (RR 1.70, 95% CI 1.08–2.70) and cesarean delivery (RR 1.21, 95% CI 1.03–1.44). Women with less than recommended gestational weight gain in the 2nd trimester had a lesser risk of cesarean deliveries (RR 0.82, 95% CI 0.71–0.96) than women with adequate gestational weight gain in this trimester. Conclusion Though insufficient weight gain in the 3rd trimester was not associated with adverse outcomes, other deviations from recommended weight gain during second and third trimester were associated with adverse pregnancy outcomes. These findings support, in part, the 2009 IOM/NRC recommendations for nutritional monitoring during pregnancy. PMID:23382944

    Objective The objective is to estimate the impact of maternal weight gain outside the 2009 Institute of Medicine recommendations on perinatal outcomes in twin pregnancies. Study Design Twin pregnancies with two live births between January 1, 2004 and December 31, 2014 delivered after 23 weeks Finger Lakes Region Perinatal Data System (FLRPDS) and Central New York Region Perinatal Data System were included. Women were classified into three groups using pre-pregnancy body mass index (BMI). Perinatal outcomes in women with low or excessive weekly maternal weight gain were assessed using normal weekly weight gain as the referent in each BMI group. Results Low weight gain increased the risk of preterm delivery, birth weight less than the 10th percentile for one or both twins and decreased risk of macrosomia across all BMI groups. There was a decreased risk of hypertensive disorders in women with normal pre-pregnancy weight and an increased risk of gestational diabetes with low weight gain in obese women. Excessive weight gain increased the risk of hypertensive disorders and macrosomia across all BMI groups and decreased the risk of birth weight less than 10th percentile one twin in normal pre-pregnancy BMI group. Conclusion Among twin pregnancies, low weight gain is associated with low birth weight and preterm delivery in all BMI groups and increased risk of gestational diabetes in obese women. Our study did not reveal any benefit from excessive weekly weight gain with potential harm of an increase in risk of hypertensive disorders of pregnancy. Normal weight gain per 2009 IOM guidelines should be encouraged to improve pregnancy outcome in all pre-pregnancy BMI groups.

    This paper aims at opening the black box of peer effects in adolescent weight gain. Using Add Health data on secondary schools in the U.S., we investigate whether these effects partly flow through the eating habits channel. Adolescents are assumed to interact through a friendship social network. We propose a two-equation model. The first equation provides a social interaction model of fast food consumption. To estimate this equation we use a quasi maximum likelihood approach that allows us to control for common environment at the network level and to solve the simultaneity (reflection) problem. Our second equation is a panel dynamic weight production function relating an individual's Body Mass Index z-score (zBMI) to his fast food consumption and his lagged zBMI, and allowing for irregular intervals in the data. Results show that there are positive but small peer effects in fast food consumption among adolescents belonging to a same friendship school network. Based on our preferred specification, the estimated social multiplier is 1.15. Our results also suggest that, in the long run, an extra day of weekly fast food restaurant visits increases zBMI by 4.45% when ignoring peer effects and by 5.11%, when they are taken into account.

    It depends. Weight doesn't appear to increase with combined oral contraception (OC) compared with nonhormonal contraception, but percent body fat may increase slightly. Depot-medroxyprogesterone acetate injection (DMPA) users experience weight gain compared with OC and nonhormonal contraception (NH) users.

    Women, particularly pregnant women, are the most vulnerable population of the society and their health status is one of the major indicators of development. There were enough studies on pre pregnancy body mass index (IPBMI) and inadequate weight gain during pregnancy (IWGP) of women in other part of the world and India, but none in Assam. In Assam a large number of population are in the category of low socio-economic group, a group most vulnerable to under nutrition. Thus this study was framed with the said indicators to throw light on the factors affecting the health status of pregnant women to accordingly address the situation. A cross sectional study using multistage sampling design with probability proportional to size was made comprising of 461 pregnant women belonging to low socio-economic status. Responses regarding their socio-economic, socio-cultural, health, diet and environmental background were collected and coded. The study revealed that although IPBMI (34.06%) was slightly lower than the reported state, national and global percentage the revealed IWGP (82%) was an astounding figure. The blood samples analyzed showed a high degree of inadequacy in almost all micronutrients (iron 63.1%, calcium 49.5% and copper 39.9%) studied in our survey.

    Pregnancy is now considered to be an important risk factor for new or persistent obesity among women during the childbearing years. High gestational weight gain is the strongest predictor of maternal overweight or obesity following pregnancy. A growing body of evidence also suggests that both high and low gestational weight gains are independently associated with an increased risk of childhood obesity, suggesting that influences occurring very early in life are contributing to obesity onset. ...

    We examined the association between exercise during pregnancy and meeting gestational weight gain recommendations. Data came from the 2009 South Carolina Pregnancy Risk Assessment Monitoring System (n = 856). Women reported their participation in exercise/sports activities before and during pregnancy, including the number of months and types of exercise. We developed an exercise index (EI), the product of the number of months spent in exercise and average metabolic equivalents for specific exercise. The 2009 Institute of Medicine's guideline was used to categorize gestational weight gain into three classes: inadequate, adequate, and excessive. Multinomial logistic regression models were used to adjust for confounders. Over 46 % of women exceeded the recommended weight gain during pregnancy. Nearly one third (31.9 %) of women reported exercising ≥3 times a week at any time during pregnancy. Compared to women who did not report this level of exercise during pregnancy, exercising women were more likely to meet gestational weight gain recommendations (32.7 vs. 18.7 %) and had a lower odds of excessive gestational weight gain [adjusted odds ratio (AOR) 0.43, 95 % confidence interval 0.24-0.78]. Women with an EI above the median value of those women who exercised or women who exercised ≥3 times a week for 6-9 months during pregnancy had lower odds of excessive gestational weight gain (AOR for EI 0.20, 0.08-0.49; AOR for months 0.26, 0.12-0.56, respectively). Our findings support the need to promote or increase exercise during pregnancy to reduce the high proportion of women who are gaining excessive weight.

    Introduction. Delta Healthy Sprouts trial was designed to test the comparative impact of two home visiting programs on weight status, dietary intake, and health behaviors of Southern African American women and their infants. Results pertaining to the primary outcome, gestational weight gain, are reported. Methods. Participants (n = 82), enrolled early in their second trimester of pregnancy, were randomly assigned to one of two treatment arms. Gestational weight gain, measured at six monthly home visits, was calculated by subtracting measured weight at each visit from self-reported prepregnancy weight. Weight gain was classified as under, within, or exceeding the Institute of Medicine recommendations based on prepregnancy body mass index. Chi-square tests and generalized linear mixed models were used to test for significant differences in percentages of participants within recommended weight gain ranges. Results. Differences in percentages of participants within the gestational weight gain guidelines were not significant between treatment arms across all visits. Conclusions. Enhancing the gestational nutrition and physical activity components of an existing home visiting program is feasible in a high risk population of primarily low income African American women. The impact of these enhancements on appropriate gestational weight gain is questionable given the more basic living needs of such women. This trial is registered with ClinicalTrials.gov NCT01746394, registered 4 December 2012. PMID:27595023

    Signe Fabricius-Bjerre

    Full Text Available BACKGROUND: Low birth weight followed by accelerated weight gain during early childhood has been associated with adverse metabolic and cardiovascular outcomes later in life. The aim of this study was to examine the impact of early infant weight gain on glucose metabolism and cardiovascular risk factors in adolescence and to study if the effect differed between adolescents born small for gestational age (SGA vs. appropriate for gestational age (AGA. METHODOLOGY/PRINCIPAL FINDINGS: Data from 30 SGA and 57 AGA healthy young Danish adolescents were analysed. They had a mean age of 17.6 years and all were born at term. Data on early infant weight gain from birth to three months as well as from birth to one year were available in the majority of subjects. In adolescence, glucose metabolism was assessed by a simplified intravenous glucose tolerance test and body composition was assessed by dual-energy X-ray absorptiometry. Blood pressures as well as plasma concentrations of triglycerides and cholesterol were measured. Early infant weight gain from birth to three months was positively associated with the fasting insulin concentration, HOMA-IR, basal lipid levels and systolic blood pressure at 17 years. There was a differential effect of postnatal weight gain on HOMA-IR in AGA and SGA participants (P for interaction = 0.03. No significant associations were seen between postnatal weight gain and body composition or parameters of glucose metabolism assessed by the simplified intravenous glucose tolerance test. In subgroup analysis, all associations with early infant weight gain were absent in the AGA group, but the associations with basal insulin and HOMA-IR were still present in the SGA group. CONCLUSION: This study suggests that accelerated growth during the first three months of life may confer an increased risk of later metabolic disturbances--particularly of glucose metabolism--in individuals born SGA.

    The aim of our study was to assess changes in body-weight in relation to active electrode contact position in the subthalamic nucleus. Regular body weight measurements were done in 20 patients with advanced Parkinson's disease within a period of 18 months after implantation. T1-weighted (1.5T) magnetic resonance images were used to determine electrode position in the subthalamic nucleus and the Unified Parkinson's disease rating scale (UPDRS-III) was used for motor assessment. The distance of the contacts from the wall of the third ventricle in the mediolateral direction inversely correlated with weight gain (r = -0.55, pweight gain (9.4 ± (SD)4.4 kg, N = 11) than those with both contacts located laterally (3.9 ± 2.7 kg, N = 9) (pweight gain, suggesting a regional effect of subthalamic stimulation on adjacent structures involved in the central regulation of energy balance, food intake or reward.

    Gestational weight gain is known to influence fetal growth. However, it is unclear whether the associations between gestational weight gain and fetal growth vary by trimester. In a diverse cohort of 8,977 women who delivered a singleton between 2011 and 2013, we evaluated the associations between trimester-specific gestational weight gain and infant size for gestational age. Gestational weight gain was categorized per the 2009 Institute of Medicine (IOM) recommendations; meeting the recommendations was the referent. Large for gestational age and small for gestational age were defined as birthweight > 90th percentile or <10th percentile, respectively, based on a national reference standard birthweight distribution. Logistic regression models estimated the odds of having a large or small for gestational age versus an appropriate for gestational age infant. Only gestational weight gain exceeding the IOM recommendations in the 2nd and 3rd trimesters independently increased the odds of delivering a large for gestational age infant (Odds Ratio (95% Confidence Interval): 1st: 1.17 [0.94, 1.44], 2nd: 1.47 [1.13, 1.92], 3rd: 1.70 [1.30, 2.22]). Gestational weight gain below the IOM recommendations increased the likelihood of having a small for gestational age infant in the 2nd trimester only (1.76 [1.23, 2.52]). There was effect modification, and gestational weight gain below the IOM recommendations increased the likelihood of having a small for gestational age infant in the 2nd trimester and only among women with a pre-pregnancy body mass index from 18.5–24.9 kg/m2 (2.06 [1.35, 3.15]). These findings indicate that gestational weight gain during the 2nd and 3rd trimesters is more strongly associated with infant growth. Interventions to achieve appropriate gestational weight gain may optimize infant size at birth. PMID:27442137

    la duración de la labor de parto y el IMC pregestacional de embarazada. Asimismo, la presencia de distocia y lesión fetal se observó más frecuentemente en pacientes con obesidad. Se pudo observar también como la ganancia de peso durante la gestación se relaciona también con la antropometría neonatal. No solo se determinó un aumento en el peso, talla y circunferencia cefálica de aquellos productos de madres que ganaron más peso de lo aconsejado por la norma, sino que el porcentaje de productos grande para edad gestacional fue mayor en este grupo. No obstante, al analizar la influencia de la ganancia de peso sobre la labor de parto, no se evidenció una diferencia significativa entre ellas. Si se toma como referencia al grupo con una ganancia de peso adecuada durante el embarazo, se puede observar que el porcentaje de recién nacidos pequeños para edad gestacional (PEG fue semejante entre este y los que presentaron una ganancia de peso menor a la recomendada, mientras que el de recién nacidos grandes para edad gestacional (GEG fue significativamente mayor en el grupo con una ganancia de peso mayor a la aconsejada. Conclusiones: El presente estudio demostró que el índice de masa corporal y la ganancia de peso durante el embarazo influye sobre el peso de los recién nacidos.Aim: To explore the relationship between pregestational body mass index (BMI and maternal weight gain during pregnancy with the newborns weight in the national health system. Materials and methods: This is a cross-sectional observational study. Three hundred and sixty medical records from pregnant patients seen at the Obstetrics Service of the Calderon Guardia Hospital were analyzed. Maternal variables related to the prenatal birth control were: age, weight, height, body mass index (kg/m2, weight gain per trimester and total weight gain through pregnancy. Labor and delivery variables included were: gestational age, mode of delivery, labor and expulsive period duration in minutes

    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.

    Full Text Available We investigate the effect of electroacupuncture (EA on protecting the weight gain side effect of rosiglitazone (RSG in type 2 diabetes mellitus (T2DM rats and its possible mechanism in central nervous system (CNS. Our study showed that RSG (5 mg/kg significantly increased the body weight and food intake of the T2DM rats. After six-week treatment with RSG combined with EA, body weight, food intake, and the ratio of IWAT to body weight decreased significantly, whereas the ratio of BAT to body weight increased markedly. HE staining indicated that the T2DM-RSG rats had increased size of adipocytes in their IWAT, but EA treatment reduced the size of adipocytes. EA effectively reduced the lipid contents without affecting the antidiabetic effect of RSG. Furthermore, we noticed that the expression of PPARγ gene in hypothalamus was reduced by EA, while the expressions of leptin receptor and signal transducer and activator of transcription 3 (STAT3 were increased. Our results suggest that EA is an effective approach for inhibiting weight gain in T2DM rats treated by RSG. The possible mechanism might be through increased levels of leptin receptor and STAT3 and decreased PPARγ expression, by which food intake of the rats was reduced and RSG-induced weight gain was inhibited.

    Drug-naive patients with schizophrenia often present metabolic abnormalities and obesity. Weight gain may be the side effect of treatment with many antipsychotic drugs. Genetic effects, besides many other factors, are known to influence obesity in patients with schizophrenia treated with antipsychotics. Numerous studies of several genes' polymorphisms have been performed. -759C/T polymorphism of 5HT2C gene attracted most attention. In 5 independent studies of this polymorphism the association between T allele with the lower AP-induced weight gain was detected. No associations could be detected between weight gain and other polymorphisms of serotonergic system genes as well as histaminergic system genes. Studies of adrenergic and dopaminergic system have neither produced any unambiguous results. Analysis of the newest candidate genes (SAP-25, leptin gene) confirmed the role of genetic factors in AP-induced weight gain. It is worth emphasising, that the studies have been conducted in relatively small and heterogenic groups and that various treatment strategies were used.

    Background Gestational diabetes mellitus (GDM) is a common complication during pregnancy,and gestational weight gain is one of the major and modifiable risk factors.This study aims to estimate the relationship between the rate of gestational weight gain before diagnosis of GDM and the subsequent risk of GDM.Methods A case-control study was conducted with 90 GDM cases and 165 women in the control group from May 2012 to August 2012 at Peking University First Affiliated Hospital.GDM was diagnosed according to the standards issued by the Ministry of Health of China in 2011.The plasma glucose levels,weights,and covariate data of the women were obtained based on medical records.Univariate analysis and unconditional Logistic regression model were used to estimate the associations.Results After adjusting for age at delivery,parity,and pre-pregnancy body mass index,the risk of GDM increased with increasing rates of gestational weight gain.Compared with the lower rate of gestational weight gain (less than 0.28 kg per week),a rate of weight gain of 0.28 kg per week or more was associated with increased risk of GDM (odds ratio:2.03; 95% confidence interval:1.15 to 3.59).The association between the rate of gestational weight gain and GDM was primarily attributed to the increased weight gain in the first trimester.Conclusion High rates of gestational weight gain,particular during early pregnancy,may increase a woman's risk of GDM.

    Does eating good-tasting food influence body weight? To investigate, we first established some concentrations of sucralose and mineral oil in chow that mice strongly preferred. Then, in Experiment 1, we compared groups of 16 mice fed plain chow (i.e., chow with no additives) to groups fed chow with added (a) sucralose, (b) mineral oil, (c) sucralose and mineral oil, or (d) sucralose on odd days and mineral oil on even days. During a 6-week test, the body weights and body compositions of the five groups never differed. In Experiment 2, we compared groups of 18 mice fed plain chow or plain high-fat diet to groups fed these diets with added sucralose. During a 9-week test, the high-fat diet caused weight gain, but the body weights of mice fed the sucralose-sweetened diets did not differ from those fed the corresponding plain versions. Two-cup choice tests conducted at the end of each experiment showed persisting strong preferences for the diets with added sucralose and/or mineral oil. In concert with earlier work, our results challenge the hypothesis that the orosensory properties of a food influence body weight gain. A good taste can stimulate food intake acutely, and guide selection toward nutrient-dense foods that cause weight gain, but it does not determine how much is eaten chronically.

    Pregnancy is now considered to be an important risk factor for new or persistent obesity among women during the childbearing years. High gestational weight gain is the strongest predictor of maternal overweight or obesity following pregnancy. A growing body of evidence also suggests that both high and low gestational weight gains are independently associated with an increased risk of childhood obesity, suggesting that influences occurring very early in life are contributing to obesity onset. In response to these data, the US Institute of Medicine (IOM) revised gestational weight gain guidelines in 2009 for the first time in nearly two decades. However, less than one third of pregnant women achieve guideline-recommended gains, with the majority gaining above IOM recommended levels. To date, interventions to optimize pregnancy weight gains have had mixed success. In this paper, we summarize the evidence from human and animal studies linking over-nutrition and under-nutrition in pregnancy to maternal and child obesity. In addition, we discuss published trials and ongoing interventions to achieve appropriate gestational weight gain as a strategy for obesity prevention in women and their children.

    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.

    The prevalence of weight disorders among school-aged children is an increasing phenomenon and it is of great importance to identify the characteristics of individuals at risk of gaining or retaining weight. This study aimed to examine the prevalence of weight disorders and their tracking over a 3-year period in a sample of Italian children. Body mass, body height and selected skinfold thicknesses were assessed in 355 children at the age of 7 and 10 years. Tracking of body mass index (BMI), inverted BMI (iBMI) and skinfold-based body fat were analyzed and the relationships between changes in BMI and body fat were examined. Children presenting with overweight or obesity at 7 years old showed a trend toward lower weight categories at 10 years old. Conversely, a trend to become overweight was observed among normal weight boys, and a trend to become underweight was observed among normal weight girls. BMI, iBMI and body fat showed good levels of tracking, with high correlations between measurements performed at 7 and 10 years of age. Furthermore, BMI and iBMI changes were correlated to body fatness changes. The present study shows the importance of carefully following children's development over time because weight disorders may appear even in previously normal weight children.

    Several hypotheses have been put forward to explain weight gain after deep brain stimulation (DBS), but none provides a fully satisfactory account of this adverse effect. We analyzed the correlation between changes in brain metabolism (using positron emission tomography [PET] imaging) and weight gain after bilateral subthalamic nucleus DBS in patients with Parkinson's disease. Body mass index was calculated and brain activity prospectively measured using 2-deoxy-2[18F]fluoro-D-glucose 3 months before and 4 months after the start of subthalamic nucleus deep brain stimulation in 23 patients with Parkinson's disease. Motor complications (United Parkinson's Disease Rating Scale [UPDRS]-IV scores) and dopaminergic medication were included in the analysis to control for their possible influence on brain metabolism. Mean ± standard deviation (SD) body mass index increased significantly by 0.8 ± 1.5 kg/m(2) (P = 0.03). Correlations were found between weight gain and changes in brain metabolism in limbic and associative areas, including the orbitofrontal cortex (Brodmann areas [BAs] 10 and 11), lateral and medial parts of the temporal lobe (BAs 20, 21, 22,39 and 42), anterior cingulate cortex (BA 32), and retrosplenial cortex (BA 30). However, we found no correlation between weight gain and metabolic changes in sensorimotor areas. These findings suggest that changes in associative and limbic processes contribute to weight gain after subthalamic nucleus DBS in Parkinson's disease.

  1. Modelling body weight, dieting and obesity traps

    Barbieri, Paolo Nicola

    2017-02-01

    This paper presents a theoretical investigation into why losing weight is so difficult even in the absence of rational addiction, time-inconsistent preferences or bounded rationality. We add to the existing literature by focusing on the role that individual metabolism has on weight loss. The results from the theoretical model provide multiple steady states and a threshold revealing a situation of "obesity traps" that the individual must surpass in order to successfully lose weight. Any weight-loss efforts that the individual undertakes have to surpass such threshold in order to result in permanent weight loss, otherwise the individual will gradually regain weight and converge to his or her previous body weight.

    Cessation of drug use often coincides with increased food consumption and weight gain in recovering addicts. However, it is not known whether this phenomenon (particularly the weight gain) is uniquely human, or whether it represents a consequence of drug cessation common across species. To address this issue, rats (n = 10/group) were given systemic injections of D-amphetamine (3 mg/kg) or an equal volume of saline vehicle for 9 consecutive days. Beginning 2 days after the final injection, rats were given free access to a highly palatable food mixture (consisting of sugar and butter) along with their standard chow diet, and food consumption and body weight were measured every 48 h for 30 days. Consistent with clinical observations, amphetamine-treated rats showed a greater increase in body weight over the course of the 30 days relative to vehicle-treated rats. Surprisingly, there was no difference in highly palatable food consumption between amphetamine- and vehicle-treated groups, but the amphetamine-treated group consumed significantly more standard chow than the control group. The finding that a history of chronic amphetamine exposure increases food consumption is consistent with previous work in humans showing that withdrawal from drugs of abuse is associated with overeating and weight gain. The current findings may reflect amphetamine-induced sensitization of mechanisms involved in reward motivation, suggesting that weight gain following drug cessation in humans could be due to similar mechanisms.

    Full Text Available Probiotics has been used to substitute antibiotic treatments used as growth promoters and to improve productive performance. The term probiotic is used to namelive micro-organisms such as microbes and bacteria with beneficial effects to livestock farms when consumed as dietary supplements. This review investigates the evidence for the use of probiotics in sheep’s final body weight gain combined with livestock grazing management system with yeast (Saccharomyces cerevisiae. Twenty one native sheep were chosen randomly for this study, with an average weight of 14.71 kg ± 1.9 under continuous grazing; the meadows are used as sheep pastures where Kikuyo grass grows (Pennisetum clandestinum and water ad libitum. Sheep were classified in three different treatments: T1, control treatment, without adding yeast; T2, added with 5 g/day of yeast; and T3, supplemented with 15 g/day of yeast. Throughout this study was possible to find a beneficial effect on final weight and average daily gain. The results were compared by ANOVA with a significance level of 95%. A significant difference was observed on final body weight of sheep for T3 (p ≤ 0.05. In addition, it was found that daily weight gain was 100 g, 120 g and 220 g for T1, T2 and T3 respectively. This research leads us to conclude that the addition of 15 g of yeast improves daily bodyweight gain and final weight of grazing native sheep.

    The purpose of this study was to characterize the magnitude of acute weight gain (AWG) and dehydration in mixed martial arts (MMA) fighters before competition. Urinary measures of hydration status and body mass were determined approximately 24 hours before and then again approximately 2 hours before competition in 40 MMA fighters (mean ± SE, age: 25.2 ± 0.65 years, height: 1.77 ± 0.01 m, body mass: 75.8 ± 1.5 kg). The AWG was defined as the amount of body weight the fighters gained in the approximately 22-hour period between the official weigh-in and the actual competition. On average, the MMA fighters gained 3.40 ± 2.2 kg or 4.4% of their body weight in the approximately 22-hour period before competition. Urine specific gravity significantly decreased (p 1.021 immediately before competition indicating significant or serious dehydration. The MMA fighters undergo significant dehydration and fluctuations in body mass (4.4% avg.) in the 24-hour period before competition. Urinary measures of hydration status indicate that a significant proportion of MMA fighters are not successfully rehydrating before competition and subsequently are competing in a dehydrated state. Weight management guidelines to prevent acute dehydration in MMA fighters are warranted to prevent unnecessary adverse health events secondary to dehydration.

    Full Text Available The aim of our study was to assess changes in body-weight in relation to active electrode contact position in the subthalamic nucleus. Regular body weight measurements were done in 20 patients with advanced Parkinson's disease within a period of 18 months after implantation. T1-weighted (1.5T magnetic resonance images were used to determine electrode position in the subthalamic nucleus and the Unified Parkinson's disease rating scale (UPDRS-III was used for motor assessment. The distance of the contacts from the wall of the third ventricle in the mediolateral direction inversely correlated with weight gain (r = -0.55, p<0.01 and with neurostimulation-related motor condition expressed as the contralateral hemi-body UPDRS-III (r = -0.42, p<0.01. Patients with at least one contact within 9.3 mm of the wall experienced significantly greater weight gain (9.4 ± (SD4.4 kg, N = 11 than those with both contacts located laterally (3.9 ± 2.7 kg, N = 9 (p<0.001. The position of the active contact is critical not only for motor outcome but is also associated with weight gain, suggesting a regional effect of subthalamic stimulation on adjacent structures involved in the central regulation of energy balance, food intake or reward.

    子代发生超重肥胖的风险更高,OR(95%CI)值分别为2.90(1.97~4.28)、3.17(1.44~6.97)。结论母亲孕前较高的BMI和不适宜的孕期增重是导致学龄前儿童超重肥胖的危险因素;孕妇应采取科学的方法调整孕前BMI,并根据孕前BMI控制孕期增重,以在生命早期预防学龄前儿童超重肥胖的发生。%Objective To examine the effect of maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with childhood overweight and adiposity, and to explore possible early life risk factors for obesity in preschool children. Methods Basic information of pregnant women and gestation period came from the Ma'anshan Birth Cohort Study,a part of the China-Anhui Birth Cohort Study (C-ABCS) . Pregnant women in routine health care from four municipal medical and health institutions were enrolled voluntarily during October 2008 and October 2010 in Ma'anshan City. A total of 5 084 pregnant women and 4 669 singleton live births were included in this study. Between April 2014 and April 2015, 3 797 children were followed up. Children whose BMI were>85th percentiles for age and genders of World Health Organization (WHO) reference were considered as overweight, and >95th percentiles for age and genders cut-off values were considered as obesity (pathological and secondary causes of obesity were excluded). Gestational weight gain was defined according to the Institute of Medicine (IOM) guidelines. Univariate and binary regression model analysis was used to examine the effect of pre-pregnancy BMI and GWG with childhood overweight and adiposity. Results Of the 3 797 pregnant women, the prevalence of underweight, normal weight, overweight and obesity were respectively 22.6%(n=858), 70.3%(n=2 671), 6.2%(n=234) and 0.9% (n=34). There were 3 563 pregnant women who were obtained gestational weight gain data, the prevalence of inadequate GWG, appropriate GWG, excessive GWG were respectively 12.4%(n=443), 25

    The rates of child and adult obesity have increased in most developed countries over the past several decades. The health consequences of obesity affect both physical and mental health, and the excess body weight can be linked to an elevated risk for developing type 2 diabetes, cardiovascular problems, and depression. Among the factors that can influence the development of obesity are higher infant weights and increased weight gain, which are associated with higher risk for excess body weight later in life. In turn, mother's excess body weight during and after pregnancy can be linked to the risk for offspring overweight and obesity through dietary habits, mode of delivery and feeding, breast milk composition, and through the influence on infant gut microbiota. This review considers current knowledge of these potential mechanisms that threaten to create an intergenerational cycle of obesity.

    Full Text Available Preeclamptic twin pregnancy with larger gestational weight gain (GWG is suggested to have a higher risk of peripartum cardiomyopathy (PPCM. This was true in a 5-year experience at a single center. A primiparous woman with twins and prepregnancy weight of 51.0 kg exhibited hypertension at gestational week (GW 32−6/7 and GWG of 18.3 kg (6.0 kg and 2.9 kg during the last four weeks and one week of gestation, resp. concomitant with generalized edema, gave birth at GW 34−4/7, developed proteinuria, cough, and dyspnea postpartum, and was diagnosed with preeclampsia and PPCM showing left ventricular ejection fraction of 34% and plasma BNP level of 1530 pg/mL. This was the only case of PPCM among 101 (12 with preeclampsia and 3266 women with twin and singleton pregnancies, respectively. Thus, PPCM occurred significantly more often in women with preeclamptic twin pregnancies than in women with singleton pregnancies (8.3% [1/12] versus 0.0% [0/3266], P=0.0355. This patient showed the greatest weight gain of 6.0 kg during the last four weeks of gestation and the greatest weight loss of 19.2 kg during one month postpartum among 90 women with twin deliveries at GW ≥ 32.

    Background Previous studies have shown an association between total excessive gestational weight gain and hypertension in pregnancy. However, this may be a reflection of excessive water retention associated with the pathophysiology of hypertensive disorders of pregnancy. Early excessive weight gain, prior to the third trimester, results in greater maternal fat deposition and inflammation, which has also been associated with the development of hypertension. By focusing on early excessive weight gain, the association between maternal weight gain and the future development of hypertension can be examined. Objective To evaluate the association between early excessive maternal weight gain and the development of hypertension during pregnancy. Study Design This was a secondary analysis of a longitudinal cohort study of 1,441 women without chronic hypertension who were enrolled in a prospective study evaluating maternal angiogenic factors and the prediction of preeclampsia. Initial body mass index (BMI) was calculated by weight and height at the first study visit. Early excessive maternal weight gain was defined as weight gain by 28 weeks that exceeded the Institute of Medicine (IOM) guidelines and was calculated utilizing the maximum amount of weight gain per week recommended by the IOM based on the patient's starting BMI (normal: 0.45 kg; overweight: 0.32 kg; obese: 0.27 kg). Hypertension was defined as a sustained systolic blood pressure of ≥140 mm Hg or a diastolic blood pressure of ≥90 mm Hg. Logistic regression was used to determine the association between early excessive weight gain, initial BMI, and the development of hypertension, including gestational hypertension and preeclampsia, during pregnancy. Results Of 1,441 women, 767 (53.2%) had weight gain that exceeded the IOM guidelines in the first 28 weeks and 154 (10.8%) developed hypertension during pregnancy. Women whose weight gain exceeded the IOM guidelines were more likely to develop

    The body is the place where the dimensions of space, time, subjectivity and objectivity meet and interact. These dimensions are considered with regard to eating, sleeping and sex within the couple. When a disfunctioning appears in one of these three fundamental aspects, it is, in general, treated alone. Eating, sleeping and sex are, on the contrary, interdependant, and in this perspective, a therapeutical intervention on one of these vital functions can lead to an amelioration of another one of them.

    Prenatal maternal immune activation has been used to test the neurodevelopmental hypothesis of schizophrenia. Most of the data are in mouse models; far less is available for rats. We previously showed that maternal weight change in response to the immune activator polyinosinic-polycytidylic acid (Poly IC) in rats differentially affects offspring. Therefore, we treated gravid Harlan Sprague-Dawley rats i.p. on embryonic day 14 with 8 mg/kg of Poly IC or Saline. The Poly IC group was divided into those that lost or gained the least weight, Poly IC (L), versus those that gained the most weight, Poly IC (H), following treatment. The study design controlled for litter size, litter sampling, sex distribution, and test experience. We found no effects of Poly IC on elevated zero maze, open-field activity, object burying, light-dark test, straight channel swimming, Morris water maze spatial acquisition, reversal, or shift navigation or spatial working or reference memory, or conditioned contextual or cued fear or latent inhibition. The Poly IC (H) group showed a significant decrease in the rate of route-based learning when visible cues were unavailable in the Cincinnati water maze and reduced prepulse inhibition of acoustic startle in females, but not males. The Poly IC (L) group exhibited altered responses to acute pharmacological challenges: exaggerated hyperactivity in response to (+)-amphetamine and an attenuated hyperactivity in response to MK-801. This model did not exhibit the cognitive, or latent inhibition deficits reported in Poly IC-treated rats but showed changes in response to drugs acting on neurotransmitter systems implicated in the pathophysiology of schizophrenia (dopaminergic hyperfunction and glutamatergic hypofunction).

    In recent years, the prevalence of hypertension and prehypertension increased markedly among children and adolescents, highlighting the importance of identifying determinants of elevated blood pressure early in life. Low birth weight and rapid early childhood weight gain are associated with higher...... future blood pressure. However, few studies have examined the timing of postnatal weight gain in relation to later blood pressure, and little is known regarding the contribution of linear growth. We studied 957 participants in Project Viva, an ongoing US prebirth cohort. We examined the relations...... of gains in body mass index z-score and length/height z-score during 4 early life age intervals (birth to 6 months, 6 months to 1 year, 1 to 2 years, and 2 to 3 years) with blood pressure during mid-childhood (6-10 years) and evaluated whether these relations differed by birth size.

    Full Text Available Introduction. Prenatal care is considered an important tool for promoting a healthy lifestyle, but has not been studied as a predictor for maternal weight gain during pregnancy, especially in Romania, where evidence about pregnancy and nutrition is scarce. Objective. This study has aimed to explore the relationship between pre-gestational body mass index (BMI, adequacy of prenatal care and weight gain during pregnancy. Methods. We carried a cross-sectional study on a sample of 400 pregnant women admitted at the “Cuza Voda” Obstetrics and Gynecology Hospital in Iasi. Information regarding demographic characteristics, number of prenatal visits, date of the initial hospital record, nutritional education during pregnancy were registered throughout a questionnaire filled out by means of a direct interview. The anthropometric indicators analyzed were the pre-gestational BMI and the pregnancy weight gain. Data on caloric intake were obtained using a food frequency questionnaire. Results. Weight gain within the limits of the Institute of Medicine recommendations was noticed at 44.35% of the women who declared that they received nutritional advice compared to 40.7% of those who did not receive advice regarding diet during pregnancy. Overweight (53.1% and obese women (66.7% had a larger weight gain than those with a normal pre-pregnancy BMI (29.8% (p<0.001. The variables that were identified with an effect on weight gain in this sample of pregnant women were: inadequate prenatal care, pre-gestational BMI and energy intake. Conclusion. Identifying the pre-gestational BMI and diet changes as predictors of weight gain underline the importance of an individualized prenatal care.

    Objective Determine whether early weight gain predicts full remission at end-of-treatment (EOT) and follow-up in two different treatments for adolescent anorexia nervosa, and to track the rate of weight gain throughout treatment and follow-up. Method Participants were 121 adolescents with AN (mean age = 14.4 years, SD = 1.6), from a two-site (Chicago and Stanford) randomized controlled trial. Adolescents were randomly assigned to family-based treatment (FBT) (n=61) or individual adolescent supportive psychotherapy (AFT) (n=60). Treatment response was assessed using percent of expected body weight (EBW) and the global score on the Eating Disorder Examination (EDE). Full remission was defined as having achieved ≥95% EBW and within one standard deviation of the community norms of the EDE. Full remission was assessed at EOT as well as 12-month follow-up. Results Receiver operating characteristic analyses showed that the earliest predictor of remission at EOT was a gain of 5.8 pounds (2.65 kg) by session 3 in FBT (AUC = .670; p=.043), and a gain of 7.1 pounds (3.20 kg) by session 4 in AFT (AUC=0.754, p=.014). Early weight gain did not predict remission at follow-up for either treatment. A survival analysis showed that weight was marginally superior in FBT as opposed to AFT (Wald chi-square=3.692, df=1, p=.055). Conclusion Adolescents with AN who receive either FBT or AFT, and show early weight gain, are likely to remit at EOT. However, FBT is superior to AFT in terms of weight gain throughout treatment and follow-up. PMID:24190844

    The relationship between the body weight or weight gain during pregnancy and various obstetrical factors was investigated in 731 patients who delivered in San-ikukai Hospital for in the year 1986. The patients were classified into three groups according to their body weight in non-pregnant states: slender (n = 214), ordinary (n = 379) and obese (n = 138), according to the standard for "The decision diagram for the estimation of obesity and emaciation in Japanese" published in 1986 by the Ministry of Health and Welfare, Japan. Each of these groups was further divided into two groups according to the degree of weight gain during pregnancy (more or less than 15kg). Then, the duration of labor, the blood loss during delivery, the birth weight, the placental weight and the obstetrical abnormalities (prolonged labor, arrested labor, blood loss of more than 500 ml, fetal distress and toxemia of pregnancy) were investigated in these groups. The blood loss, the neonatal birth weight and the placental weight in the obese groups were much greater than those in the ordinary or the slender group (p less than 0.005). However, there was no significant difference in the duration of the labor among these groups. The incidence of obstetrical abnormalities in the obese group was significantly higher than in the ordinary or the slender group (chi 2 = 4.37, p less than 0.05, chi 2 = 5.27, p less than 0.025).(ABSTRACT TRUNCATED AT 250 WORDS)

    Olanzapine (OLZ), one of the second-generation atypical antipsychotics (SGAs), has shown relative advantages in patient adherence and outcomes. However, OLZ has also been associated with a higher incidence of weight gain than most other SGAs. Excessive weight gain may in turn contribute to long-term health concerns for some individuals. Zonisamide (ZNS), a medication approved in the United States as an adjunct in the management of epilepsy, has a diverse pharmacological profile, including sodium channel blockade, monoamine enhancement, and inhibition of carbonic anhydrase. ZNS has also been reported to cause weight loss in both humans and rodents. We hypothesized that this profile might be beneficial when co-administered with OLZ. To test this hypothesis, we evaluated the effects of OLZ on body weight, as well as the pathways known to regulate feeding behavior and arousal in the Sprague-Dawley rat. As indicated via c-Fos expression, we found an OLZ-induced activation in the nucleus accumbens and orexin neurons in the lateral hypothalamus. An OLZ-associated development of hyperphagia, weight gain and elevated blood glucose in the rat was also found. These outcomes were attenuated and reversed in the presence of concomitant ZNS. These results suggest the hypothesis that ZNS may effectively treat or prevent weight gain or metabolic changes associated with the SGAs. Future studies of this combination in patients through appropriately designed human clinical studies are encouraged.

    The gestational weight gain (GWG) guidelines of the Institute of Medicine (IOM) aim to optimize birth outcomes and reduce pregnancy complications. The GWG guidelines are set based on the prepregnancy weight status and optimal weight gain at different trimesters of pregnancy. Dietary references intakes (DRIs) of the IOM are set for each trimester of pregnancy for energy intake and other essential nutrients by age groups (≤ 18, 19-30, 31-51 years). The DRIs, however, do not take into account the differing energy and nutrient requirements of women with different prepregnancy weights. In this cross-sectional study, we tested the hypothesis that diet quality during pregnancy is associated with adequate GWG at different stages of pregnancy. Diet quality during pregnancy was assessed from a 24-h recall measured by the healthy eating index of 2005 (HEI-2005). Both GWG and diet quality data were from 490 pregnant women aged 16-43 years included in National Health and Nutrition Examination Survey 2003-2006, a program of studies designed to assess the health and nutritional status of adults and children in the US, during which pregnant women were oversampled. Logistic regression models adjusted for age, trimester of gestation, race/ethnicity, education level, marital status, family poverty income ratio, daily supplement use, physical activity, and prepregnancy BMI were used to investigate if HEI-2005 is a determinant of GWG status at different trimesters of pregnancy. We found that HEI-2005 scores were not determinants of adequate GWG, although inadequate intake of total vegetables (OR 3.8, CI 1.1-13.2, p = 0.03) and oils were associated with excessive GWG (OR 2.8, CI 1.2-6.4, p = 0.02) when covariates were controlled. Although adequate GWG was not associated with diet quality as measured by HEI-2005 during pregnancy in this study, comprehensive prenatal counseling is still important to reduce adverse birth outcomes.

    Although obesity is associated with osteoarthritis, it is unclear whether body weight (BW) independently affects articular cartilage catabolism (i.e., independent from physiological factors that also accompany obesity). The primary purpose of this study was to evaluate the independent effect of BW on articular cartilage catabolism associated with walking. A secondary purpose was to determine how decreased BW influenced cardiovascular response due to walking. Twelve able-bodied subjects walked for 30 minutes on a lower-body positive pressure treadmill during three sessions: control (unadjusted BW), +40%BW, and -40%BW. Serum cartilage oligomeric matrix protein (COMP) was measured immediately before (baseline) and after, and 15 and 30 minutes after the walk. Heart rate (HR) and rate of perceived exertion (RPE) were measured every three minutes during the walk. Relative to baseline, average serum COMP concentration was 13% and 5% greater immediately after and 15 minutes after the walk. Immediately after the walk, serum COMP concentration was 14% greater for the +40%BW session than for the -40%BW session. HR and RPE were greater for the +40%BW session than for the other two sessions, but did not differ between the control and -40%BW sessions. BW independently influences acute articular cartilage catabolism and cardiovascular response due to walking: as BW increases, so does acute articular cartilage catabolism and cardiovascular response. These results indicate that lower-body positive pressure walking may benefit certain individuals by reducing acute articular cartilage catabolism, due to walking, while maintaining cardiovascular response. Key pointsWalking for 30 minutes with adjustments in body weight (normal body weight, +40% and -40% body weight) significantly influences articular cartilage catabolism, measured via serum COMP concentration.Compared to baseline levels, walking with +40% body weight and normal body weight both elicited significant increases in

    Metabolic adaptation to weight changes relates to body weight control, obesity and malnutrition. Adaptive thermogenesis (AT) refers to changes in resting and non-resting energy expenditure (REE and nREE) which are independent from changes in fat-free mass (FFM) and FFM composition. AT differs in response to changes in energy balance. With negative energy balance, AT is directed towards energy sparing. It relates to a reset of biological defence of body weight and mainly refers to REE. After weight loss, AT of nREE adds to weight maintenance. During overfeeding, energy dissipation is explained by AT of the nREE component only. As to body weight regulation during weight loss, AT relates to two different set points with a settling between them. During early weight loss, the first set is related to depleted glycogen stores associated with the fall in insulin secretion where AT adds to meet brain's energy needs. During maintenance of reduced weight, the second set is related to low leptin levels keeping energy expenditure low to prevent triglyceride stores getting too low which is a risk for some basic biological functions (e.g., reproduction). Innovative topics of AT in humans are on its definition and assessment, its dynamics related to weight loss and its constitutional and neuro-endocrine determinants.

    Full Text Available The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT strain tilapia (Oreochromis sp. selected for weight gain. The data set used contained information on 6,650 animals. The genetic values of 8,590 animals in a relationship matrix of five generations were predicted. The following morphometric measurements were evaluated: standard length; body depth and body width. Body area and volume were also calculated. Bi-character analyses involving morphometric traits were used to estimate (covariance components. Heritability, larval and fingerling common environmental effects were estimated for each trait, together with the genetic and phenotypic correlations between traits. Bayesian procedures were utilised by Gibbs chains, and the convergence of the chains was tested using the Heidelberger and Welch method. Genetic trends were estimated by segmented regression of the fish breeding values of the generations considered in this study. Estimates of heritability (0.28 a 0.31 had moderate to high magnitudes for all traits. Genetic correlations between traits were all above 0.8, and the genetic gains were satisfactory from the third generation onwards. From the estimates of the genetic parameters and genetic gain the morphometric traits evaluated have good potential for selection.

    The prevalence of obesity and overweight has increased in almost all Western countries in the past twenty to thirty years, with social disparities in many of these countries. This paper contributes to the literature on the relation between education and body weight by studying the effect of higher...... education on body weight according to subgroups of parental income background. To uncover the causal relationship between higher education and body weight, we use a reform of the Danish student grant scheme, which involved a grant increase of approximately 60% in 1988. When using this reform as instrumental...... variable, we find no effect among men of higher education on the probability of being either overweight or healthy-weighted. However, we find suggestive evidence that the effect differs by income background. Amongst men who grew up in low-income households, enrolling in higher education increases...

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

    Obesity in preschoolers has risen dramatically in the last decade. Although studies have demonstrated that parents of preschoolers have incorrect perceptions of their child's body weight, little is known about the factors that may be associated with these perceptions. The purpose of this study was to examine the relationships between parental perceptions of preschool child body weight and parental psychosocial factors. Quantitative analyses included descriptive statistics, correlations, and regression analyses. More than one third of the children in the sample were at risk for being overweight or were already overweight. However, less than 6% of parents felt that their child had an elevated body weight. Results from univariate logistic regression analyses demonstrated that the parent's health literacy level was a significant predictor of the accuracy of their perceptions regarding their child's body weight (p perceptions. Results from this study indicate that assessing parental perceptions of preschool child body weight can help providers accurately understand how parents view their children and lead to tailored educational interventions. In addition, the results support previous research suggesting that parental health literacy is a key to providing high-quality family-centered care.

  11. Olanzapine-high potency antipsychotic drug inducing significant weight gain: A case report

    Full Text Available INTRODUCTION Olanzapine is a second generation antipsychotic (SGA with a high level of therapeutic effectiveness in schizophrenia and other psychotic disorders. Along with the positive therapeutic effects, an increase of the body weight frequently occurs. According to the literature, the average weight gain is about 6-7 kg during several months of treatment. This could be valued as a moderate weight increase. CASE OUTLINE This article presents a case of a young female with schizophrenia, without clinical improvement with several antipsychotics (clozapine, risperidone, haloperidol and with the occurrence of significant neurological side effects. The treatment started with olanzapine (baseline was associated with good initial response (PANSS reduction 20% in the first two weeks and the improvement was maintained further on (PANSS reduction 50% after 16 weeks. Significant increase (20 kg, 40% in weight appeared during the following 16 weeks (BMI at baseline 17.9 kg/m2; BMI 16 weeks later 25.1 kg/m2. CONCLUSION High effectiveness of olanzapine in schizophrenia symptoms reduction was accompanied by a significant weight gain. However, this drug leads to impaired glucoregulation, dyslipidaemia etc. It also increases the risk of diabetes and cardio-vascular diseases, i.e. the main causes of mortality in schizophrenia after a suicide. Therefore, clinicians are suggested to focus on possible predictors of weight gain during olanzapine therapy, and act accordingly in order to prevent serious health consequences.

    It has been suggested that the use of nonnutritive sweeteners (NNSs) can lead to weight gain, but evidence regarding their real effect in body weight and satiety is still inconclusive. Using a rat model, the present study compares the effect of saccharin and aspartame to sucrose in body weight gain and in caloric intake. Twenty-nine male Wistar rats received plain yogurt sweetened with 20% sucrose, 0.3% sodium saccharin or 0.4% aspartame, in addition to chow and water ad libitum, while physical activity was restrained. Measurements of cumulative body weight gain, total caloric intake, caloric intake of chow and caloric intake of sweetened yogurt were performed weekly for 12 weeks. Results showed that addition of either saccharin or aspartame to yogurt resulted in increased weight gain compared to addition of sucrose, however total caloric intake was similar among groups. In conclusion, greater weight gain was promoted by the use of saccharin or aspartame, compared with sucrose, and this weight gain was unrelated to caloric intake. We speculate that a decrease in energy expenditure or increase in fluid retention might be involved.

  13. Weight Gain, Schizophrenia and Antipsychotics: New Findings from Animal Model and Pharmacogenomic Studies

    Full Text Available Excess body weight is one of the most common physical health problems among patients with schizophrenia that increases the risk for many medical problems, including type 2 diabetes mellitus, coronary heart disease, osteoarthritis, and hypertension, and accounts in part for 20% shorter life expectancy than in general population. Among patients with severe mental illness, obesity can be attributed to an unhealthy lifestyle, personal genetic profile, as well as the effects of psychotropic medications, above all antipsychotic drugs. Novel “atypical” antipsychotic drugs represent a substantial improvement on older “typical” drugs. However, clinical experience has shown that some, but not all, of these drugs can induce substantial weight gain. Animal models of antipsychotic-related weight gain and animal transgenic models of knockout or overexpressed genes of antipsychotic receptors have been largely evaluated by scientific community for changes in obesity-related gene expression or phenotypes. Moreover, pharmacogenomic approaches have allowed to detect more than 300 possible candidate genes for antipsychotics-induced body weight gain. In this paper, we summarize current thinking on: (1 the role of polymorphisms in several candidate genes, (2 the possible roles of various neurotransmitters and neuropeptides in this adverse drug reaction, and (3 the state of development of animal models in this matter. We also outline major areas for future research.

    This study aimed to investigate the optimal degree of weight gain across the gestational spectrum in 1971 children enrolled at birth and followed up to age 7 years. Weight gain in infancy was categorized into four groups based on weight gain z-scores: slow (1.28). Underweight and overweight or obesity (OWO) were defined as a body mass index ≤5(th) and ≥85(th) percentile, respectively, for age and gender. In our population, OWO was far more common than underweight (39.7% vs. 3.6%). Weight gain tracked strongly from age 4 to 24 months, and was positively associated with OWO and an unfavorable pattern of metabolic biomarkers, although the degree of weight gain for the risk was different across gestational categories. Extremely rapid weight gain led to a particularly high risk of OWO among children born early term and late preterm: odds ratio: 3.3 (95% confidence interval: 1.9 to 5.5) and 3.7 (1.8 to 7.5), respectively, as compared to those with on track weight gain. Our findings suggest that monitoring and ensuring optimal weight gain across the entire gestational spectrum beginning from birth represents a first step towards primary prevention of childhood obesity.

    Full Text Available Background. Increasing body mass index (BMI is associated with increased risk of mortality; however, quantifying weight gain in men undergoing androgen deprivation therapy (ADT for prostate cancer (PC remains unexplored. Methods. Between 1995 and 2001, 206 men were enrolled in a randomized trial evaluating the survival difference of adding 6 months of ADT to radiation therapy (RT. BMI measurements were available in 171 men comprising the study cohort. The primary endpoint was weight gain of ≥10 lbs by 6-month followup. Logistic regression analysis was performed to assess whether baseline BMI or treatment received was associated with this endpoint adjusting for known prognostic factors. Results. By the 6-month followup, 12 men gained ≥10 lbs, of which 10 (83% received RT + ADT and, of these, 7 (70% were obese at randomization. Men treated with RT as compared to RT + ADT were less likely to gain ≥10 lbs (adjusted odds ratio (AOR: 0.18 [95% CI: 0.04–0.89]; P=0.04, whereas this risk increased with increasing BMI (AOR: 1.15 [95% CI: 1.01–1.31]; P=0.04. Conclusions. Consideration should be given to avoid ADT in obese men with low- or favorable-intermediate risk PC where improved cancer control has not been observed, but shortened life expectancy from weight gain is expected.

    Growing evidence links perceived stress—a potentially modifiable psychosocial risk factor—with health behaviors and obesity. Yet little is known about the relationship between stress during pregnancy and gestational weight gain, particularly among women with pregnancy complications. We conducted a cross-sectional analysis to examine associations between psychosocial stress during pregnancy and gestational weight gain among women with gestational diabetes. We used baseline data from the Gestational Diabetes’s Effects on Moms (GEM) study: 1,353 women with gestational diabetes who delivered a term singleton within Kaiser Permanente Northern California were included. Perceived stress near the time of gestational diabetes diagnosis was measured using the validated Perceived Stress Scale (PSS10). Gestational weight gain was categorized according to the 2009 Institute of Medicine recommendations. Binomial regression analyses adjusted for gestational age and maternal age at the time of gestational diabetes diagnosis, and race/ethnicity and estimated rate ratios (RR) and their 95% confidence interval (CI). Among women with a normal pregravid Body Mass Index (BMI 18.5–24.9 kg/m2), there was a significant association between high (Q4) PSS score and risk of both exceeding and gaining below the Institute of Medicine recommendations compared to those with lower stress (Q1) [adjusted RR = 2.16 95% CI 1.45–3.21; RR = 1.39 95% CI 1.01–1.91, respectively.] Among women with pregravid overweight/obesity (BMI≥25 kg/m2), there was no association. Although the temporal relationship could not be established from this study, there may be a complex interplay between psychosocial stress and gestational weight gain among women with gestational diabetes. Further studies examining stress earlier in pregnancy, risk of developing gestational diabetes and excess/inadequate gestational weight gain are warranted to clarify these complex relationships.

    OBJECTIVE To test the hypothesis that greater chocolate-candy intake is associated with more weight gain in postmenopausal women. DESIGN AND METHODS Prospective cohort study involving 107,243 post-menopausal American women aged 50–79 years (mean=60.7) at enrolment in the Women’s Health Initiative (WHI), with three-year follow up. Chocolate-candy consumption was assessed by food frequency questionnaire and body weight was measured. Linear mixed models, adjusted for demographic, socio-economic, anthropomorphic and behavioral variables, were used to test our main hypotheses. RESULTS Compared to women who ate a 1 oz (~28 g) serving of chocolate candy <1 per month, those who ate this amount 1 per month to <1 per week, 1 per week to < 3 per week and ≥3 per week showed greater three-year prospective weight gains (kg) of 0.76 (95% CI: 0.66, 0.85), 0.95 (0.84, 1.06) and 1.40 (1.27, 1.53), respectively, (p for linear trend<0.0001). Each additional 1 oz/day was associated with a greater three-year weight gain (kg) of 0.92 (0.80, 1.05). The weight gain in each chocolate-candy intake level increased as BMI increased above the normal range (18.5–25 kg/m2), and as age decreased. CONCLUSIONS Greater chocolate-candy intake was associated with greater prospective weight gain in this cohort of post-menopausal women. PMID:25644711

    Full Text Available O presente trabalho foi realizado na Universidade Federal de Santa Maria, com o intuito de avaliar a composição corporal e exigências líquidas de energia e proteína de novilhos. Foi conduzido um experimento com uma dieta contendo 70% de silagem de milho e 30% de concentrado. Foram utilizados 40 novilhos Santa Gertrudis, com 3,5 anos de idade, sendo quatro deles abatidos no início do experimento e 36 distribuídos ao acaso nos tratamentos e abatidos no final do período experimental. De cada carcaça foi retirada uma secção da 9ª à 11ª costela e determinada a sua composição física e química, através do que foi estimada a composição corporal. Foram ajustadas as equações lineares entre log do conteúdo de proteína, gordura e energia do corpo vazio e log do peso do corpo vazio. Constatou-se que, ao aumentar o peso do corpo vazio, o conteúdo de proteína desse corpo e do seu ganho de peso diminui, enquanto os de gordura e energia aumentam. Assim, os animais de maior peso corporal vazio apresentam exigências de energia mais elevadas e de proteína inferiores às dos animais de menor peso.The present work was carried out at Universidade Federal de Santa Maria to evaluate composition of the body and body weight gain. A experiment was conducted with 70% of corn silage and 30% of concentrate. Forty 3,5 years old Santa Gertrudis steers were used; four of them were slaughtered at the beginning of the experiment and 36 were randomly assigned to the treatments and slaughtered at the end of the experimental period. From each carcass the 9th to 11th rib section was taken and its physical and chemical composition determined, and from this the body composition was estimated. Linear equations between log of protein, fat and energy content in the empty body and log of empty body weight were fitted. It was observed that increasing empty body weight decreased the content of protein in empty body and in empty body weight gain while it increased

    Full Text Available Abstract Background The incidence of weight gain is highest during young adulthood. Our study aims to describe weight gain patterns among young adults and to evaluate physician recognition of and counseling for rapid weight gain. Methods This retrospective cohort study included patients ages 18-35 at an academic internal medicine clinic between 2004-2008. We conducted chart reviews to determine weight change over time, whether weight gain greater than 3 lbs/year was documented, whether counseling was provided, and whether patients became overweight. We categorized weight gain documentation by location on the problem list, encounter diagnosis, or note text. We categorized counseling as weight-specific or general diet and exercise counseling. We used Chi-square tests to evaluate the relationship between weight change over time and the following variables: gender, diagnosis of weight gain, and counseling for weight gain. Fisher's Exact test was used to test for an association between diagnosis and counseling category. Results The study included 365 patients. Weight gain was greater than 3 lbs/year for 24% (90/365 of patients, of whom 56 (15% gained 3-5.9 lbs/year, and 34 (9% gained more than 6 lbs/year. Among patients gaining more than 3 lbs/year, physicians documented weight gain as a problem in only 10% (9/90. Of the 9 patients for whom weight gain was documented, physicians provided weight-specific counseling in three, and general diet and exercise counseling in four. Of the 81 individuals with no documented diagnosis of weight gain, 63% had no documented counseling, but 34% received general diet and exercise counseling. Among patients with over 180 days of follow-up, 8% (10/126 became overweight. Conclusions Physicians infrequently recognize or counsel for weight gain among young adult patients. Improving identification of patients with rapid weight gain can provide an opportunity for tailored weight-related counseling.

    Full Text Available Objectives. To systematically review the evidence from prospective and retrospective cohort studies on the association between gestational weight gain (GWG and offspring’s body weight. Methods. Electronic databases PubMed, Web of Science, CINAHL, and Academic Search Premiere were searched from inception through March 18, 2013. Included studies (n=23 were English articles that examined the independent associations of GWG with body mass index (BMI and/or overweight status in the offspring aged 2 to 18.9 years. Two authors independently extracted the data and assessed methodological quality of the included studies. Results. Evidence from cohort studies supports that total GWG and exceeding the Institute of Medicine maternal weight gain recommendation were associated with higher BMI z-score and elevated risk of overweight or obesity in offspring. The evidence of high rate of GWG during early- and mid-pregnancy is suggestive. Additionally, the evidence on inadequate GWG and net GWG in relation to body weight outcomes in offspring is insufficient to draw conclusions. Conclusions. These findings suggest that GWG is a potential risk factor for childhood obesity. However, findings should be interpreted with caution due to measurement issues of GWG and potential confounding effects of shared familial characteristics (i.e., genetics and maternal and child’s lifestyle factors.

    To determine prospectively whether physical activity canprevent age-related weight gain and whether changing levels of activityaffect body weight. DESIGN/SUBJECTS: The study consisted of 8,080 maleand 4,871 female runners who completed two questionnaires an average(+/-standard deviation (s.d.)) of 3.20+/-2.30 and 2.59+/-2.17 yearsapart, respectively, as part of the National Runners' Health Study.RESULTS: Changes in running distance were inversely related to changes inmen's and women's body mass indices (BMIs) (slope+/-standard error(s.e.): -0.015+/-0.001 and -0.009+/-0.001 kg/m(2) per Deltakm/week,respectively), waist circumferences (-0.030+/-0.002 and -0.022+/-0.005 cmper Deltakm/week, respectively) and percent changes in body weight(-0.062+/-0.003 and -0.041+/-0.003 percent per Deltakm/week,respectively, all P<0.0001). The regression slopes were significantlysteeper (more negative) in men than women for DeltaBMI and Deltapercentbody weight (P<0.0001). A longer history of running diminishedthe impact of changing running distance on men's weights. When adjustedfor Deltakm/week, years of aging in men and years of aging in women wereassociated with increases of 0.066+/-0.005 and 0.056+/-0.006 kg/m(2) inBMI, respectively, increases of 0.294+/-0.019 and 0.279+/-0.028 percentin Delta percentbody weight, respectively, and increases of 0.203+/-0.016and 0.271+/-0.033 cm in waist circumference, respectively (allP<0.0001). These regression slopes suggest that vigorous exercise mayneed to increase 4.4 km/week annually in men and 6.2 km/week annually inwomen to compensate for the expected gain in weight associated with aging(2.7 and 3.9 km/week annually when correct for the attenuation due tomeasurement error). CONCLUSIONS: Age-related weight gain occurs evenamong the most active individuals when exercise is constant.Theoretically, vigorous exercise must increase significantly with age tocompensate for the expected gain in weight associated withaging.

Treatments that prevent or reverse age-related increase in bone marrow adiposity could both increase new bone formation and inhibit bone destruction. We tested the hypothesis that dietary supplementation with combinations of vitamin D and phytochemicals inhibits bone loss and decreases adiposity to a greater extent than control or vitamin D-alone diets. Aged ovariectomized female rats (12 months old, n=50, initial body weight=240 g) were given control (AIN-93M diet), vitamin D (2,400 IU/kg), or vitamin D plus resveratrol (16, 80, or 400 mg/kg of diet [low, medium, and high dose, respectively]), quercetin (80, 400, or 2,000 mg/kg of diet), and genistein (64, 256, or 1,040 mg/kg of diet) for 8 weeks. The high-dose treatment (vitamin D+400 mg/kg resveratrol+2,000 mg/kg quercetin+1,040 mg/kg genistein) reduced body weight gain (P<.05) and the fat pad weights (P<.05). This treatment also increased the serum concentration of insulin-like growth factor-1 (P<.05) and the bone mineral content of the femur. Micro-computed tomography and histomorphometric analyses indicated that the high-dose treatment prevented loss of trabecular bone (P<.05) and reduced marrow adipocytes (P<.001) and osteoclasts (P<.05) compared with the control and vitamin D alone (P<.05). We conclude that aged ovariectomized female rats supplemented with vitamin D combined with genistein, quercetin, and resveratrol had improved bone mineral density and reduced body weight gain and a significant decrease in bone marrow adipocytes. The synergistic effects of a combination of phytochemicals with vitamin D may be effective in reducing bone loss and weight gain after menopause.

    Second generation antipsychotic drugs (SGAs) cause substantial body weight gain/obesity and other metabolic side-effects such as dyslipidaemia. Their antagonistic affinity to the histaminergic H1 receptor (H1R) has been identified as one of the main contributors to weight gain/obesity side-effects. The effects and mechanisms of betahistine (a histaminergic H1R agonist and H3 receptor antagonist) have been investigated for ameliorating SGA-induced weight gain/obesity in both animal models and clinical trials. It has been demonstrated that co-treatment with betahistine is effective in reducing weight gain, associated with olanzapine in drug-naïve patients with schizophrenia, as well as in the animal models of both drug-naïve rats and rats with chronic, repeated exposure to olanzapine. Betahistine co-treatment can reduce food intake and increase the effect of thermogenesis in brown adipose tissue by modulating hypothalamic H1R-NPY-AMPKα (NPY: neuropeptide Y; AMPKα: AMP-activated protein kinase α) pathways, and ameliorate olanzapine-induced dyslipidaemia through modulation of AMPKα-SREBP-1-PPARα-dependent pathways (SREBP-1: Sterol regulatory element binding protein 1; PPARα: Peroxisome proliferator-activated receptor-α) in the liver. Although reduced locomotor activity was observed from antipsychotic treatment in rats, betahistine did not affect locomotor activity. Importantly, betahistine co-treatment did not influence the effects of antipsychotics on serotonergic receptors in the key brain regions for antipsychotic therapeutic efficacy. However, betahistine co-treatment reverses the upregulated dopamine D2 binding caused by chronic olanzapine administration, which may be beneficial in reducing D2 supersensitivity often observed in chronic antipsychotic treatment. Therefore, these results provide solid evidence supporting further clinical trials in treating antipsychotics-induced weight gain using betahistine in patients with schizophrenia and other mental

    BACKGROUND: In Danish data, the tradeoffs between mother and infant in the risks of adverse pregnancy outcomes were reached at lower gestational weight gain (GWG) among multiparous than among primiparous women. It is unknown whether the same difference exists among American women. OBJECTIVE......: The objective was to determine whether these tradeoffs also differ by parity among women in a contemporary American birth cohort. DESIGN: Data from 822 primiparous and 2055 multiparous American women who participated in the Infant Feeding Practices Study II (2005-2007), a national cohort study, were analyzed...... by multiple logistic regression analyses for women in 3 categories of prepregnancy body mass index. RESULTS: Primiparous women gained more weight during pregnancy than did multiparous women (mean ± SD: 15.9 ± 6.9 compared with 13.5 ± 6.2 kg; P

    To compare body mass index (BMI) and daily energy intake (DEI) after subthalamic versus pallidal deep brain stimulation (DBS). Weight gain following DBS in Parkinson's disease patients remains largely unexplained and no comparison of subthalamic and pallidal (GPi) stimulation has yet been performed. BMI and DEI, dopaminergic drug administration and motor scores were recorded in 46 patients with PD before STN (n = 32) or GPi (n = 14) DBS and 3 and 6 months after. At M6, BMI had increased by an average of 8.4% in the STN group and 3.2% in the GPi group. BMI increased in 28 STN and 9 GPi patients. This increase was significantly higher in the STN group (P weight gain, inadequately explained by motor improvement or reduced dopaminergic drug dosage, occurred in subthalamic DBS patients. The difference between groups suggests additional factors in the STN group, such as homeostatic control center involvement.

    Our aim was to confirm in our environment what has been observed and described by other writers about the importance of achieving a "critical body weight'' and an adequate "fat percentage'' -on the basis of the calculation of total body water- for the initiation and development of pubertal events. This study included 92 girls, healthy, well nourished, belonging to upper middle class from a high school of The National University of Cordoba. The longitudinal method of control was used every 6 months and at the precise moment of menarche. Out of 20 antropometrical variables observed height, weight and height, TBW as percentage of body weight, lean body and fat weight, fat percentage and skin folds ppercentiles for each girl at menarche. A regression between fat percentage and skin folds was done. Percentiles 5 to 95 of fat percentage in relation to body water percentage were estimated. At menarche the average for the different variables are: Heigth 155.6 cm +/- 0.469; Weight 45.8 Kg +/- 0,5; TBW 25.216 lit. +/- 0.318; lean body weigth 35.02 Kg (S.D.2.98); fat weigth 10.86 Kg (S. D. 3.17). The addition of skin folds was correlated fat percentage, thus, an equation was obtained for the average calculation of such percentage %F= 12.16 + (0.313 x fold addition). The minium percentage for the onset of menstrual cycles is 17.3% and corresponds to percentile 10. However, there is a 5% of girls who start to menstruate with a 15.5% of fat and none of them is below that value. The reasons mentioned above suggest that is necessary to obtain a "critical body weigth'' as well as a "fat percentage'' minimum for the onset and maintenance of menstrual cycles, among our girls, similar o what has been obtained by doctor Frisch.

    A retrospective chart review characterizing changes in 17 male and 10 female Parkinson's disease (PD) patients undergoing deep brain stimulation (DBS) surgery indicated that 6 mo before surgery, patients lost a mean of 5.1 lbs, whereas in the 6 mo after surgery, subjects gained a mean of 10.1 lbs; 22% gained more than 14 lbs. In 10 patients followed an additional 6 mo, weight gain continued. This weight gain may be associated with decreased energy expenditure due to subsidence of chronic tremor. The magnitude of gain underscores the need for proactive management of body weight in PD patients undergoing DBS.

    Olanzapine is effective at treating multiple domains of schizophrenia symptoms. However, it induces serious metabolic side effects. Antipsychotic drug's antagonistic affinity to histamine H₁ receptors has been identified as a main contributor for weight gain/obesity side effects. This study therefore investigated whether a combined treatment of betahistine (a H₁ receptor agonist and H₃ receptor antagonist) could reduce the body weight/obesity induced by olanzapine. Female Sprague Dawley rats were treated orally with olanzapine (1 mg/kg, t.i.d.) and/or betahistine (2.67 mg/kg, t.i.d.), or vehicle for two weeks. Rats treated with olanzapine exhibited significant body weight gain and increased food intake. Co-treatment of olanzapine with betahistine significantly prevented (-45%) weight gain and reduced feeding efficiency compared to sole olanzapine treatment. Betahistine treatment alone had no effect on weight gain and food intake. Olanzapine reduced locomotor activity, but not betahistine. These findings demonstrate that olanzapine-induced body weight gain can partially be reduced by co-treatment with betahistine. Betahistine has H₃ receptor antagonistic effects to increase histamine release, which may augment its direct agonistic effects on H₁ receptors. These findings have important implications for clinical trials using betahistine to control antipsychotic-induced obesity side effects.

    2006-01-06

    Background: Body weight increases with aging. Short-term,longitudinal exercise training studies suggest that increasing exerciseproduces acute weight loss, but it is not clear if the maintenance oflong-term, vigorous exercise attenuates age-related weight gain inproportion to the exercise dose. Methods: Prospective study of 6,119 maleand 2,221 female runners whose running distance changed less than 5 km/wkbetween their baseline and follow-up survey 7 years later. Results: Onaverage, men who ran modest (0-24 km/wk), intermediate (24-48 km/wk) orprolonged distances (>_48 km/wk) all gained weight throughage 64,however, those who ran ?48 km/wk had one-half the average annual weightgain of those who ran<24 km/wk. Age-related weight gain, and itsreduction by running, were both greater in younger than older men. Incontrast, men s gain in waist circumference with age, and its reductionby running, were the same in older and younger men. Women increased theirbody weight and waist and hip circumferences over time, regardless ofage, which was also reduced in proportion to running distance. In bothsexes, running did not attenuate weight gain uniformly, but ratherdisproportionately prevented more extreme increases. Conclusion: Men andwomen who remain vigorously active gain less weight as they age and thereduction is in proportion to the exercise dose.

    Full Text Available The objective of this study was evaluate the effects of immunocastration on body weight gain, carcass characteristics and meat quality of Nellore beef cattle. Eighty Nellore beef cattle, with initial body weight of 357±8.63 kg, were placed in feedlots and distributed in two treatments (40 animals per treatments as follow: one - non-vaccinated bulls and two - immunocastrated bulls (Bopriva®, Pfizer Animal Health. The animals placed on treatment two were vaccinated in two doses, first application 30 days before they arrive on the feedlots and second on the day they arrive on feedlots. After 67 days of experimental period, was calculated the daily gain of live weight in kg/day of the 80 animals and selected 20 animals from each treatment for the slaughter and carcass evaluations, and ten from each group for the meat analyzes. The data were submitted to analysis of variance. Immunocastrated animals showed lower daily weight gain, hot carcass weight, carcass yield, pH, leg thickness, muscle depth, loin muscle area, carcass muscle percentage, shear force and moisture. However, this animals had higher concentration of lactate and cortisol blood, chest depth, fat thickness, finishing degree, a *, b * and c*, liquid loss in thawing process, myofibrillar fragmentation index and ether extract of meat when compared to non-vaccinated bulss. The immunocastration (Bopriva® is an alternative for improving the quality of meat by the higher fat deposition and by the reduction of the shear force of the meat when compared to non-vaccinated bulls.

    Full Text Available The purpose of the review was to summarise the effect of some commonly available natural products used for body weight management. We collected data from PubMed and scientific journals. There are numerous publications on this topic, however we have summarized the most commonly available and potent natural products from recent 53 publications. The natural products analyzed in this paper include catechins, capsaicin, conjugated linoleic acid, fucoxanthin, soy isoflavone, glabridin, astaxanthin and cyaniding-3-glucoside. These natural products are effective and safe for body weight management. Further studies need to be conducted to investigate the mechanism of action, metabolism, long term safety and side effects of these natural products, as well as interactions between these natural products with dietary components.

  1. Alterations to melanocortinergic, GABAergic and cannabinoid neurotransmission associated with olanzapine-induced weight gain.

    Full Text Available BACKGROUND/AIM: Second generation antipsychotics (SGAs are used to treat schizophrenia but can cause serious metabolic side-effects, such as obesity and diabetes. This study examined the effects of low to high doses of olanzapine on appetite/metabolic regulatory signals in the hypothalamus and brainstem to elucidate the mechanisms underlying olanzapine-induced obesity. METHODOLOGY/RESULTS: Levels of pro-opiomelanocortin (POMC, neuropeptide Y (NPY and glutamic acid decarboxylase (GAD(65, enzyme for GABA synthesis mRNA expression, and cannabinoid CB1 receptor (CB1R binding density (using [(3H]SR-141716A were examined in the arcuate nucleus (Arc and dorsal vagal complex (DVC of female Sprague Dawley rats following 0.25, 0.5, 1.0 or 2.0 mg/kg olanzapine or vehicle (3×/day, 14-days. Consistent with its weight gain liability, olanzapine significantly decreased anorexigenic POMC and increased orexigenic NPY mRNA expression in a dose-sensitive manner in the Arc. GAD(65 mRNA expression increased and CB1R binding density decreased in the Arc and DVC. Alterations to neurotransmission signals in the brain significantly correlated with body weight and adiposity. The minimum dosage threshold required to induce weight gain in the rat was 0.5 mg/kg olanzapine. CONCLUSIONS: Olanzapine-induced weight gain is associated with reduced appetite-inhibiting POMC and increased NPY. This study also supports a role for the CB1R and GABA in the mechanisms underlying weight gain side-effects, possibly by altering POMC transmission. Metabolic dysfunction can be modelled in the female rat using low, clinically-comparable olanzapine doses when administered in-line with the half-life of the drug.

    The authors estimated the benchmark durations (BMDs) and their 95% lower confidence limit (BMDL) for the reference duration of shiftwork for weight gain. A 14-yr prospective cohort study was conducted in male workers at a Japanese steel company (n = 7254) who had received annual health check-ups between 1991 and 2005. The endpoints in the study were either a 5%, 7.5%, or 10% increase in body mass index (BMI) during the period of observation, compared to the BMI at entry. The association between the duration of shiftwork and weight gain was investigated using multivariate pooled logistic regression analyses with stepwise selection of covariates, including age, BMI measured during the study, drinking and smoking habits, and habitual exercise. The BMDL/BMD for shiftwork in subjects aged in their 40s or ≥50 yrs was estimated using benchmark responses (BMRs) of 5% or 10% and parameters for the duration of shiftwork and other covariates. For workers aged in their 40s, the BMDL/BMD for shiftwork with a BMR of 5% was 18.6/23.0 yrs (≥7.5%) and 16.9/19.4 yrs (≥10%). For workers aged ≥50 yrs, the BMDL/BMD with a BMR of 5% was 22.9/28.2 yrs (≥7.5%) and 20.6/23.6 yrs (≥10%). The reference duration of shiftwork that associated with weight gain was shown to be at least 17 yrs in middle-aged workers. Special attention should be paid to prevent weight gain at an earlier stage and not when this increase in weight has become apparent.

  3. The consequences of obesity and excess weight gain in pregnancy.

    Norman, Jane E; Reynolds, Rebecca M; Reynolds, Rebecca

    2011-11-01

    The prevalence of obesity in pregnancy is rising exponentially; about 15-20% of pregnant women now enter pregnancy with a BMI which would define them as obese. This paper provides a review of the strong links between obesity and adverse pregnancy outcome which operate across a range of pregnancy complications. For example, obesity is associated with an increased risk of maternal mortality, gestational diabetes mellitus, thromboembolism, pre-eclampsia and postpartum haemorrhage. Obesity also complicates operative delivery; it makes operative delivery more difficult, increases complications and paradoxically increases the need for operative delivery. The risk of the majority of these complications is amplified by excess weight gain in pregnancy and increases in proportion to the degree of obesity, for example, women with extreme obesity have OR of 7·89 for gestational diabetes and 3·84 for postpartum haemorrhage compared to their lean counterparts. The consequences of maternal obesity do not stop once the baby is born. Maternal obesity programmes a variety of long-term adverse outcomes, including obesity in the offspring at adulthood. Such an effect is mediated at least in part via high birthweight; a recent study has suggested that the odds of adult obesity are two-fold greater in babies weighing more than 4 kg at birth. The mechanism by which obesity causes adverse pregnancy outcome is uncertain. This paper reviews the emerging evidence that hyperglycaemia and insulin resistance may both play a role: the links between hyperglycaemia in pregnancy and both increased birthweight and insulin resistance have been demonstrated in two large studies. Lastly, we discuss the nature and rationale for possible intervention strategies in obese pregnant women.

  4. Consuming fire ants reduces northern bobwhite survival and weight gain

    Northern bobwhite quail, Colinus virginianus (L.) (Galliformes: Odontophoridae), population declines are well documented, but pinpointing the reasons for these decreases has proven elusive. Bobwhite population declines are attributed primarily to loss of habitat and land use changes. This, however, does not entirely explain population declines in areas intensively managed for bobwhites. Although previous research demonstrates the negative impact of red imported fire ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae) on northern bobwhites, the mechanisms underlying this effect are largely unknown. To meet the protein demands of early growth and development, bobwhite chicks predominantly consume small insects, of which ants are a substantial proportion. Fire ants alter ant community dynamics by often reducing native ant diversity and abundance while concurrently increasing the abundance of individuals. Fire ants have negative effects on chicks, but they are also a large potential protein source, making it difficult to disentangle their net effect on bobwhite chicks. To help investigate these effects, we conducted a laboratory experiment to understand (1) whether or not bobwhites consume fire ants, and (2) how the benefits of this consumption compare to the deleterious impacts of bobwhite chick exposure to fire ants. Sixty bobwhite chicks were separated into two groups of 30; one group was provided with starter feed only and the second group was provided with feed and fire ants. Bobwhite chicks were observed feeding on fire ants. Chicks that fed on fire ants had reduced survival and weight gain. Our results show that, while fire ants increase potential food sources for northern bobwhite, their net effect on bobwhite chicks is deleterious. This information will help inform land managers and commercial bobwhite rearing operations.

  5. Perceived stress and freshman weight change: the moderating role of baseline body mass index.

    Boyce, Jessica A; Kuijer, Roeline G

    2015-02-01

    The transition from high-school to university is a critical period of weight change. Popular media suggest that freshman students gain 15 lb (6.80 kg) of body weight during their first year at university (i.e., the freshman 15). In contrast, a recent meta-analysis calculated freshman weight gain to be 1.75 kg, with statistics suggesting that only a proportion of freshman students are prone to gain weight. Researchers are beginning to investigate how certain variables and interactions between such variables predict freshman weight status. The current study focused on body mass index (BMI) and psychological stress. In isolation, previous research has tested how these two variables predict freshman student's weight status. However, because BMI and stress interact to predict weight gain and weight loss in adult samples, the current study tested the interaction between student's baseline BMI and baseline stress levels to predict weight change in a New Zealand sample of freshman students (N=65). Participants completed two separate online surveys in March and October 2012 (i.e., New Zealand's academic year). Although only three students gained over 6.80 kg (i.e., the freshman 15), participants did gain a statistically significant 1.10 kg of body weight during the year. Consistent with previous research, students with a higher baseline BMI gained a higher amount of body weight. However, this main effect was qualified by an interaction between stress and BMI. Students who entered university with high levels of stress gained weight if they also had high BMIs; if they had lower BMIs then they lost weight. In order to reduce unhealthy levels of freshman weight change, vulnerable students need to be taught stress-reduction techniques and coping strategies early in the academic year.

    Full Text Available BACKGROUND: Genome-wide studies have identified several common genetic variants that are robustly associated with adult obesity risk. Exploration of these genotype associations in children may provide insights into the timing of weight changes leading to adult obesity. METHODS AND FINDINGS: Children from the Avon Longitudinal Study of Parents and Children (ALSPAC birth cohort were genotyped for ten genetic variants previously associated with adult BMI. Eight variants that showed individual associations with childhood BMI (in/near: FTO, MC4R, TMEM18, GNPDA2, KCTD15, NEGR1, BDNF, and ETV5 were used to derive an "obesity-risk-allele score" comprising the total number of risk alleles (range: 2-15 alleles in each child with complete genotype data (n = 7,146. Repeated measurements of weight, length/height, and body mass index from birth to age 11 years were expressed as standard deviation scores (SDS. Early infancy was defined as birth to age 6 weeks, and early infancy failure to thrive was defined as weight gain between below the 5th centile, adjusted for birth weight. The obesity-risk-allele score showed little association with birth weight (regression coefficient: 0.01 SDS per allele; 95% CI 0.00-0.02, but had an apparently much larger positive effect on early infancy weight gain (0.119 SDS/allele/year; 0.023-0.216 than on subsequent childhood weight gain (0.004 SDS/allele/year; 0.004-0.005. The obesity-risk-allele score was also positively associated with early infancy length gain (0.158 SDS/allele/year; 0.032-0.284 and with reduced risk of early infancy failure to thrive (odds ratio = 0.92 per allele; 0.86-0.98; p = 0.009. CONCLUSIONS: The use of robust genetic markers identified greater early infancy gains in weight and length as being on the pathway to adult obesity risk in a contemporary birth cohort.

  7. Compact Weighted Class Association Rule Mining using Information Gain

    2011-01-01

    Weighted association rule mining reflects semantic significance of item by considering its weight. Classification constructs the classifier and predicts the new data instance. This paper proposes compact weighted class association rule mining method, which applies weighted association rule mining in the classification and constructs an efficient weighted associative classifier. This proposed associative classification algorithm chooses one non class informative attribute from dataset and all the weighted class association rules are generated based on that attribute. The weight of the item is considered as one of the parameter in generating the weighted class association rules. This proposed algorithm calculates the weight using the HITS model. Experimental results show that the proposed system generates less number of high quality rules which improves the classification accuracy.

A cross-sectional survey was conducted amongst 661 adolescents (324 males; 337 females) aged 12-17 years selected from government schools using a multistage stratified random sampling technique. A pretested validated questionnaire was employed to determine the perception of adolescents toward their weight status. A nine figure silhouette illustration was used to measure perceptions of their ideal body image and how it compares with their current body weight. The results revealed that overweight (18.5%) and obesity (27.2%) were higher among males than in females (13.1% and 20.5% respectively). A high proportion of overweight males and females considered themselves as average (45.0% and 52.3%, respectively). Similarly, 56.9% of obese male and 46.4% of females considered themselves as average weight. Of non-overweight/obese males and females, 27.6% and 39.3% respectively, were pressured by parents to gain weight (p > 0.000). In general overweight and obese adolescents were more likely to face pressure from their parents and teased by friends than non-overweight/obese adolescents. Compared to their current body image, overweight and obese adolescents chose a significantly lighter figure as their ideal (p < 0.000). It is suggested that the current health education curriculum should include information related to healthy body weight and appropriate diet and lifestyle so as to minimize risk of developing distorted body image concerns in adolescence and beyond.

    Expression of β-Kotho, fibroblast growth factor receptor (FGFR)-1c and 2c, which bind FGF21, is decreased in the white adipose tissue of obese mice. The aim of the present study was to determine the role of FGFR2c in the development of obesity and diabetes in KKAy mice. Treatment with mouse monoclonal FGFR2-IIIc antibody (0.5 mg kg−1) significantly suppressed body weight gain and epididymal white adipose tissue weight in individually housed KKAy mice while having no effect on daily food intake. In addition, treatment with FGFR2-IIIc antibody significantly increased plasma-free fatty acid levels while having no effect on blood glucose or plasma FGF21 levels. Moreover, treatment with FGFR2-IIIc antibody had no significant effect on the expression of uncoupling protein-1, uncoupling protein-2 or peroxisome proliferator-activated receptor-γ coactivator 1α in the epididymal white adipose tissue. The treatment with FGFR2-IIIc antibody had no significant effects on daily food intake and body weight gain in individually housed KK mice. These findings suggest that FGFR2-IIIc upregulates the adiposity induced by social isolation in KKAy mice, and that decreased expression and/or function of FGFR2c might be a compensatory response to enhanced adiposity. Inhibition of FGFR2-IIIc function might be a novel therapeutic approach for obesity. PMID:27892934

    The increasing worldwide incidence of obesity and the limitations of current treatments raise the need for finding novel therapeutic approaches to treat this disease. The purpose of the current study was first to investigate the effects of tungstate on body weight and insulin sensitivity in a rat model of diet-induced obesity. Second, we aimed to gain insight into the molecular mechanisms underlying its action. Oral administration of tungstate significantly decreased body weight gain and adiposity without modifying caloric intake, intestinal fat absorption, or growth rate in obese rats. Moreover, the treatment ameliorated dislipemia and insulin resistance of obese rats. These effects were mediated by an increase in whole-body energy dissipation and by changes in the expression of genes involved in the oxidation of fatty acids and mitochondrial uncoupling in adipose tissue. Furthermore, treatment increased the number of small adipocytes with a concomitant induction of apoptosis. Our results indicate that tungstate treatment may provide the basis for a promising novel therapy for obesity.

    Excessive weight gain is common after renal transplantation, but it is unknown whether environmental factors, such as food availability, contribute to this important clinical problem. We evaluated the effects of food availability (fast food restaurants, convenience stores, and grocery stores within 1, 2, and 3 mile buffers of transplant recipients' residences) on body mass index (BMI) change during the first year post-transplant. Participants (n = 299) resided in Memphis, Tennessee. BMI increased by 1.42 units (p restaurants and convenience stores were not significantly associated with BMI change.

    There is a lack of research documenting the weight-making practices of mixed-martial-arts (MMA) competitors. The purpose of the investigation was to quantify the magnitude and identify the methods of rapid weight loss (RWL) and rapid weight gain (RWG) in MMA athletes preparing for competition. Seven athletes (mean ± SD, age 24.6 ± 3.5 yrs, body mass 69.9 ± 5.7 kg, competitive experience 3.1 ± 2.2 yrs) participated in a repeated-measures design. Measures of dietary intake, urinary hydration status, and body mass were recorded in the week preceding competition. Body mass decreased significantly (p<0.0005) from baseline by 5.6 ± 1.4 kg (8 ± 1.8%). During the RWG period (32 ± 1 hours) body mass increased significantly (p<0.001) by 7.4 ± 2.8 kg (11.7 ± 4.7%), exceeding RWL. Mean energy and carbohydrate intake were 3176 ± 482 kcal·day(-1) and 471 ± 124 g·day(-1), respectively. At the official weigh-in 57% of athletes were dehydrated (1033 ± 19 mOsmol·kg(-1)) and the remaining 43% were severely dehydrated (1267 ± 47 mOsmol·kg(-1)). Athletes reported using harmful dehydration-based RWL strategies, including sauna (43%) and training in plastic suits (43%). Results demonstrated RWG greater than RWL, this is a novel finding and may be attributable to the 32 hour duration from weigh-in till competition. The observed magnitude of RWL and strategies used are comparable to those which have previously resulted in fatalities. Rule changes which make RWL impractical should be implemented with immediate effect to ensure the health, safety and wellbeing of competitors.

    Full Text Available Objectives: This study aimed to examine the effectiveness of an Islamic voluntary fasting intervention to control post-Ramadan weight gain. Methods: This study was conducted between July and November 2011. Two weight loss intervention programmes were developed and implemented among groups of overweight or obese Malay women living in the Malaysian cities of Putrajaya and Seremban: a standard programme promoting control of food intake according to national dietary guidelines (group B and a faith-based programme promoting voluntary fasting in addition to the standard programme (group A. Participants’ dietary practices (i.e., voluntary fasting practices, frequency of fruit/vegetable consumption per week and quantity of carbohydrates/protein consumed per day, body mass index (BMI, blood pressure, fasting blood high-density lipoprotein cholesterol (HDL-C and total cholesterol (TC:HDL-C ratio were assessed before Ramadan and three months post-Ramadan. Results: Voluntary fasting practices increased only in group A (P <0.01. Additionally, the quantity of protein/carbohydrates consumed per day, mean diastolic pressure and TC:HDL-C ratio decreased only in group A (P <0.01, 0.05, 0.02 and <0.01, respectively. Frequency of fruit/vegetable consumption per week, as well as HDL-C levels, increased only in group A (P = 0.03 and <0.01, respectively. Although changes in BMI between the groups was not significant (P = 0.08, BMI decrease among participants in group A was significant (P <0.01. Conclusion: Control of post-Ramadan weight gain was more evident in the faith-based intervention group. Healthcare providers should consider faith-based interventions to encourage weight loss during Ramadan and to prevent post-Ramadan weight gain among patients.

    Gestational weight gain (GWG) is a determinant of health and nutrition of mothers and offspring. However, many factors associated with GWG are not completely understood. The present study assessed the relationship between sociodemographics, dietary intake, and physical activity with GWG in 308 Iranian pregnant women attending government healthcare centres in Rafsanjan city, Iran. Women gained an average of 12.87±3.57 kg during pregnancy while 54% did not gain weight within the Institute of Medicine (IOM)-recommended range. Univariate logistic models showed that gestaional weight gain was related to age, pre-pregnancy body mass index (BMI), energy intake, and sitting time. Cumulative logit model showed positive relationship between age (p=0.0137) and pre-pregnancy BMI (pnutritional status and physical activity should be emphasized in antenatal care.

    OBJECTIVE: To investigate the effect of gestational weight gain in obese glucose-tolerant women. RESEARCH DESIGN AND METHODS: We performed a historical cohort study of 481 women with prepregnancy BMI > or = 30 kg/m2 and a normal 2-h 75-g oral glucose tolerance test (OGTT) during the third trimester.......0-11.0]). There was no difference in rates of small-for-gestational-age infants. Significant predictors for birth weight (determined by multiple linear regression) were gestational weight gain, 2-h OGTT result, pre-gestational BMI, maternal age, gestational age, and smoking. CONCLUSIONS: Increasing weight gain in obese women...... is associated with increasing pregnancy complications. Our data suggest that minimal gestational weight gain might normalize birth weight. Prospective studies should be performed to clarify the safety of recommending limited gestational weight gain....

    Full Text Available An increasing number of studies indicate that dairy products, including whey protein, alleviate several disorders of the metabolic syndrome. Here, we investigated the effects of whey protein isolate (whey in mice fed a high-fat diet hypothesising that the metabolic effects of whey would be associated with changes in the gut microbiota composition. Five-week-old male C57BL/6 mice were fed a high-fat diet ad libitum for 14 weeks with the protein source being either whey or casein. Faeces were collected at week 0, 7, and 13 and the fecal microbiota was analysed by denaturing gradient gel electrophoresis analyses of PCR-derived 16S rRNA gene (V3-region amplicons. At the end of the study, plasma samples were collected and assayed for glucose, insulin and lipids. Whey significantly reduced body weight gain during the first four weeks of the study compared with casein (P<0.001-0.05. Hereafter weight gain was similar resulting in a 15% lower final body weight in the whey group relative to casein (34.0±1.0 g vs. 40.2±1.3 g, P<0.001. Food intake was unaffected by protein source throughout the study period. Fasting insulin was lower in the whey group (P<0.01 and glucose clearance was improved after an oral glucose challenge (P<0.05. Plasma cholesterol was lowered by whey compared to casein (P<0.001. The composition of the fecal microbiota differed between high- and low-fat groups at 13 weeks (P<0.05 whereas no difference was seen between whey and casein. In conclusion, whey initially reduced weight gain in young C57BL/6 mice fed a high-fat diet compared to casein. Although the effect on weight gain ceased, whey alleviated glucose intolerance, improved insulin sensitivity and reduced plasma cholesterol. These findings could not be explained by changes in food intake or gut microbiota composition. Further studies are needed to clarify the mechanisms behind the metabolic effects of whey.

    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

In the present article we review current evidence pointing at an important role of histamine in the regulation of appetite and metabolism. Studies using both knockout mouse models as well as pharmacological studies have revealed that histamine acts as an anorexigenic agent via stimulation of histamine H(1......) receptors. One effect of histamine in the regulation of appetite is to act as a mediator of the inhibitory effect of leptin on appetite. It seems that histamine may attenuate and delay the development of leptin resistance in high-fat-diet-induced obesity. Furthermore, histamine may also act to accelerate...

    A 47 years old woman underwent autologous fat grafting to treat a 5×4 cm depression of the lower lid and the upper cheek secondary resection of squamous cell carcinoma and subsequent coverage by full thickness skin graft. 20 mL of autologous fat were harvested from lower abdomen, centrifuged and injected subcutaneously. The patient then gained a total of 15 kg over a period of 24 months. Eye dystopia developed while the grafted area became convex. MRI confirmed subcutaneous fat mass going to the orbital floor through the inferior septal defect. The fat excess was removed through a trans-conjonctival approach allowing for a progressive regression of diplopia after 2 months while the oedema reduced. The overall follow up from the resection-coverage and last examination was 5 years. In this case with a context of noticeable weight gain, the growth of a fat graft trapped between a sclerous plane and the eye, that penetrated the orbital cavity through a septal defect led have led to exophthalmos, ocular dystopia and diplopia. Systematic overcorrection in autologous fat grafting should be prevented, especially in functional areas and on low body mass index patient that might gain weight.

    Weight, body mass index (BMI) and energy expenditure/energy intake (EE/EI) was studied in 19 Parkinson's disease (PD) patients after subthalamic deep brain stimulation (STN-DBS) versus 14 nonoperated ones. Operated patients had a significant weight gain (WG, + 9.7 +/- 7 kg) and BMI increase (+ 4.7 kg/m2). The fat mass was higher after STN-DBS. Resting EE (REE; offdrug/ON stimulation) was significantly decreased in STN-DBS patients, while their daily energy expenditure (DEI) was not significantly different. A significant correlation was found among WG, BMI increase, and pre-operative levodopa-equivalent daily dose, their reduction after STN-DBS, and the differential REE related to stimulation and the REE in the offdrug/OFF stimulation condition. In conclusion, STN-DBS in PD induces a significant WG associated with a reduction in REE without DEI adjustment.

    The aim of the present study was to examine the associations of sugary drink consumption and its substitution with alternative beverages with body weight gain among young children predisposed to future weight gain. Secondary analysis of the Healthy Start Study, a 1·5-year randomised controlled trial designed to prevent overweight among Danish children aged 2-6 years (n 366), was carried out. Multivariate linear regression models were used to investigate the associations of beverage consumption with change in body weightweight) or BMI(ΔBMI) z-score. Substitution models were used to extrapolate the influence of replacing sugary drinks with alternative beverages (water, milk and diet drinks) on Δweight or ΔBMI z-score. Sugary drink intake at baseline and substitution of sugary drinks with milk were associated with both Δweight and ΔBMI z-score. Every 100 g/d increase in sugary drink intake was associated with 0·10 kg and 0·06 unit increases in body weight (P=0·048) and BMI z-score (P=0·04), respectively. Substitution of 100 g/d sugary drinks with 100 g/d milk was inversely associated with Δweight (β=-0·16 kg; P=0·045) and ΔBMI z-score (β=-0·07 units; P=0·04). The results of this study suggest that sugary drink consumption was associated with body weight gain among young children with high predisposition for future overweight. In line with the current recommendations, sugary drinks, whether high in added or natural sugar, should be discouraged to help prevent childhood obesity. Milk may be a good alternative to sugary drinks with regard to weight management among young obesity-predisposed children.

    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.

  14. Gaining effciency via weighted estimators for multivariate failure time data

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Multivariate failure time data arise frequently in survival analysis.A commonly used tech-nique is the working independence estimator for marginal hazard models.Two natural questions are how to improve the effciency of the working independence estimator and how to identify the situations under which such an estimator has high statistical effciency.In this paper,three weighted estimators are proposed based on three different optimal criteria in terms of the asymptotic covariance of weighted estimators.Simplifiedclose-form solutions are found,which always outperform the working indepen-dence estimator.We also prove that the working independence estimator has high statistical effciency,when asymptotic covariance of derivatives of partial log-likelihood functions is nearly exchangeable or diagonal.Simulations are conducted to compare the performance of the weighted estimator and work-ing independence estimator.A data set from Busselton population health surveys is analyzed using the proposed estimators.

    This study examined racial/ethnic differences in gestational weight gain (GWG) predictors and association of first-trimester GWG to overall GWG among 271 White women and 300 Latina women. Rates of within-guideline GWG were higher among Latinas than among Whites (28.7% versus 24.4%, p < 0.016). Adjusted odds of above-guideline GWG were higher among prepregnancy overweight (OR = 3.4, CI = 1.8–6.5) and obese (OR = 4.5, CI = 2.3–9.0) women than among healthy weight women and among women with above-guideline first-trimester GWG than among those with within-guideline first-trimester GWG (OR = 4.9, CI = 2.8–8.8). GWG was positively associated with neonate birth size (p < 0.001). Interventions targeting prepregnancy overweight or obese women and those with excessive first-trimester GWG are needed.

    Full Text Available The obesity epidemic requires the development of prevention policy targeting individuals most likely to benefit. We used self-reported prepregnancy body weight of all women giving birth in Nova Scotia between 1988 and 2006 to define obesity and evaluated socioeconomic, demographic, and temporal trends in obesity using linear regression. There were 172,373 deliveries in this cohort of 110,743 women. Maternal body weight increased significantly by 0.5 kg per year from 1988, and lower income and rural residence were both associated significantly with increasing obesity. We estimated an additional 82,000 overweight or obese women in Nova Scotia in 2010, compared to the number that would be expected from obesity rates of just two decades ago. The critical age for weight gain was identified as being between 20 and 24 years. This age group is an important transition age between adolescence and adulthood when individuals first begin to accept responsibility for food planning, purchasing, and preparation. Policy and public health interventions must target those most at risk, namely, younger women and the socially deprived, whilst tackling the marketing of low-cost energy-dense foods at the expense of healthier options.

  18. Role of oxytocin signaling in the regulation of body weight.

    Obesity and its associated metabolic disorders are growing health concerns in the US and worldwide. In the US alone, more than two-thirds of the adult population is classified as either overweight or obese [1], highlighting the need to develop new, effective treatments for these conditions. Whereas the hormone oxytocin is well known for its peripheral effects on uterine contraction during parturition and milk ejection during lactation, release of oxytocin from somatodendrites and axonal terminals within the central nervous system (CNS) is implicated in both the formation of prosocial behaviors and in the control of energy balance. Recent findings demonstrate that chronic administration of oxytocin reduces food intake and body weight in diet-induced obese (DIO) and genetically obese rodents with impaired or defective leptin signaling. Importantly, chronic systemic administration of oxytocin out to 6 weeks recapitulates the effects of central administration on body weight loss in DIO rodents at doses that do not result in the development of tolerance. Furthermore, these effects are coupled with induction of Fos (a marker of neuronal activation) in hindbrain areas (e.g. dorsal vagal complex (DVC)) linked to the control of meal size and forebrain areas (e.g. hypothalamus, amygdala) linked to the regulation of food intake and body weight. This review assesses the potential central and peripheral targets by which oxytocin may inhibit body weight gain, its regulation by anorexigenic and orexigenic signals, and its potential use as a therapy that can circumvent leptin resistance and reverse the behavioral and metabolic abnormalities associated with DIO and genetically obese models.

    chronic diseases in adult life such as metabolic syndrome for cases of low birth weight and diabetes and obesity for macrossomic infants. The objective of this study was to describe a cohort of pregnant women according to their nutritional status, gestational weight gain, uterine artery notches, and birth weight. METHODS: A cohort of 115 pregnant women attending the Family Health Program in Campina Grande, PB, was evaluated every four gestational weeks. The initial maternal nutritional status was determined through the body mass index (kg/m² and women were classified according to Atalah´s criteria for gestational age. Arterial resistance was assessed through Doppler velocimetry on the 20th week of pregnancy. RESULTS: overweight and obesity were observed in 27% of the sample whereas 23% were undernourished. A high incidence of excessive weight gain was found in the second (44% and in the third quarter (45%. Birth weight distribution indicated that 10% were of low birth weight and there were 9% of macrossomic babies. A high prevalence of uterine artery diastolic notches of was observed.

    This study assessed young adults' beliefs about weight gain with the goal of improving intervention efforts with this high-risk group. A total of 1,347 incoming freshman (45% male; 81% non-Hispanic white; 18.6 ± 1.7 years; BMI = 23.3 ± 2.3 kg/m2) at a large state university in the Northeast completed a survey designed to assess: (i) degree of concern about weight gain, (ii) level of interest in weight control programs, and (iii) the most acceptable setting for an intervention. Perceptions about freshman weight gain were consistent across gender, with men and women reporting that the average student gains 5.4 ± 1.9 kg and 5.6 ± 1.9 kg respectively. Men in general were less concerned about weight gain (P gain 6.2 ± 4.2 kg before becoming concerned compared to 3.1 ± 1.7 kg among women (P gaining weight than normal weight (NW) men (P gain less weight before becoming concerned (5.0 ± 3.0 kg vs. 6.7 ± 4.5 kg, P prevent weight gain (17% men vs. 40% women, P prevention program did not vary by weight status (P = 0.59). Both men and women were most likely to report a willingness to attend classes on a local college campus compared to other settings. Findings highlight the challenges of engaging young adults in weight gain prevention programs, particularly young men, and are discussed in terms of implications for improving recruitment efforts and intervention development with this population.

    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.

    Full Text Available Because of concerns related to the use of antibiotics in animal agriculture, antibiotic-free alternatives are greatly needed to prevent disease and promote animal growth. One of the current challenges facing commercial turkey production in Minnesota is difficulty obtaining flock average weights typical of the industry standard, and this condition has been coined “Light Turkey Syndrome” or LTS. This condition has been identified in Minnesota turkey flocks for at least five years, and it has been observed that average flock body weights never approach their genetic potential. However, a single causative agent responsible for these weight reductions has not been identified despite numerous efforts to do so. The purpose of this study was to identify the bacterial community composition within the small intestines of heavy and light turkey flocks using 16S rRNA sequencing, and to identify possible correlations between microbiome and average flock weight. This study also sought to define the temporal succession of bacteria occurring in the turkey ileum. Based upon 2.7 million sequences across nine different turkey flocks, dominant operational taxonomic units (OTUs were identified and compared between the flocks studied. OTUs that were associated with heavier weight flocks included those with similarity to Candidatus division Arthromitus and Clostridium bartlettii, while these flocks had decreased counts of several Lactobacillus species compared to lighter weight flocks. The core bacterial microbiome succession in commercial turkeys was also defined. Several defining markers of microbiome succession were identified, including the presence or abundance of Candidatus division Arthromitus, Lactobacillus aviarius, Lactobacillus ingluviei, Lactobacillus salivarius, and Clostridium bartlettii. Overall, the succession of the ileum bacterial microbiome in commercial turkeys proceeds in a predictable manner. Efforts to prevent disease and promote growth in

    Olanzapine is widely used to treat schizophrenia and other disorders, but causes adverse obesity and other metabolic side-effects. Both animal and clinical studies have shown that co-treatment with betahistine (a histaminergic H1 receptor agonist and H3 receptor antagonist) is effective for ameliorating olanzapine-induced weight gain/obesity. To reveal the mechanisms underlying these effects, this study investigated the effects of co-treatment of olanzapine and betahistine (O+B) on expressions of histaminergic H1 receptor (H1R), AMP-activated protein kinase (AMPK), neuropeptide Y (NPY), and proopiomelanocortin (POMC) in the hypothalamus associated with reducing olanzapine-induced weight gain. Olanzapine significantly upregulated the mRNA and protein expressions of H1R, while O+B co-treatment significantly downregulated the H1R levels, compared to the olanzapine-only treatment group. The NPY mRNA expression was significantly enhanced by olanzapine, but it was significantly reversed by O+B co-treatment. The hypothalamic H1R expression was positively correlated with total food intake, and NPY expression. Olanzapine also increased AMPKα activation measured by the AMPKα phosphorylation (pAMPKα)/AMPKα ratio compared with controls, whereas O+B co-treatment decreased the pAMPKα/AMPKα ratio, compared with olanzapine only treatment. The pAMPKα/AMPKα ratio was positively correlated with total food intake and H1R expression. Although olanzapine administration decreased the POMC mRNA level, this level was not affected by O+B co-treatment. Therefore, these results suggested that co-treatment with betahistine may reverse olanzapine-induced body weight gain via the H1R-NPY and H1R-pAMPKα pathways.

    Although cardiovascular risks decrease after quitting smoking, body weight often increases in the early period after smoking cessation. We have previously reported that the serum level of the α1-antitrypsin-low-density lipoprotein complex (AT-LDL)-an oxidatively modified low-density lipoprotein that accelerates atherosclerosis-is high in current smokers, and that the level rapidly decreases after smoking cessation. However, the effects of weight gain after smoking cessation on this cardiovascular marker are unknown. In 183 outpatients (134 males, 49 females) who had successfully quit smoking, serum AT-LDL levels were measured using an enzyme-linked immunosorbent assay. For all persons who had successfully quit smoking, body mass index (BMI) significantly increased 12 weeks after the first examination (p smoking is influenced by weight gain after smoking cessation.

    The objective of this study was to examine the associations of working conditions with major weight gain. Three different groups of work-related factors were examined: (i) work arrangements, (ii) physical working conditions, and (iii) psychosocial working conditions. The data are based on the Helsinki Health Study (HHS) questionnaire surveys. A baseline mail survey was made among middle-aged employees of the City of Helsinki in 2000-2002. A follow-up survey was made in 2007. Regression analyses with odds ratios and 95% confidence intervals were calculated. During the 5- to 7-year follow-up, 26% of women and 24% of men gained in weight 5 kg or more. Working conditions were mostly unassociated with weight gain. However, nighttime shift work, physical threat at work, and hazardous exposures at work were moderately associated with weight gain. More attention should be devoted to the prevention of weight gain in general and among risk groups in particular.

    Olanzapine is the one of first line antipsychotic drug for schizophrenia and other serious mental illness. However, it is associated with troublesome metabolic side-effects, particularly body weight gain and obesity. The antagonistic affinity to histamine H1 receptors (H1R) of antipsychotic drugs has been identified as one of the main contributors to weight gain/obesity side-effects. Our previous study showed that a short term (2 weeks) combination treatment of betahistine (an H1R agonist and H3R antagonist) and olanzapine (O+B) reduced (-45%) body weight gain induced by olanzapine in drug-naïve rats. A key issue is that clinical patients suffering with schizophrenia, bipolar disease and other mental disorders often face chronic, even life-time, antipsychotic treatment, in which they have often had previous antipsychotic exposure. Therefore, we investigated the effects of chronic O+B co-treatment in controlling body weight in female rats with chronic and repeated exposure of olanzapine. The results showed that co-administration of olanzapine (3 mg/kg, t.i.d.) and betahistine (9.6 mg/kg, t.i.d.) significantly reduced (-51.4%) weight gain induced by olanzapine. Co-treatment of O+B also led to a decrease in feeding efficiency, liver and fat mass. Consistently, the olanzapine-only treatment increased hypothalamic H1R protein levels, as well as hypothalamic pAMPKα, AMPKα and NPY protein levels, while reducing the hypothalamic POMC, and UCP1 and PGC-1α protein levels in brown adipose tissue (BAT). The olanzapine induced changes in hypothalamic H1R, pAMPKα, BAT UCP1 and PGC-1α could be reversed by co-treatment of O+B. These results supported further clinical trials to test the effectiveness of co-treatment of O+B for controlling weight gain/obesity side-effects in schizophrenia with chronic antipsychotic treatment.

    Histamine antagonism has been implicated in antipsychotic drug-induced weight gain. Betahistine, a histamine enhancer with H1 agonistic/H3 antagonistic properties (48 mg t.i.d.), was coadministered with olanzapine (10 mg/day) in three first-episode schizophrenia patients for 6 weeks. Body weight was measured at baseline and weekly thereafter. Clinical rating scales were completed at baseline and at week 6. All participants gained weight (mean weight gain 3.1+/-0.9 kg) and a similar pattern of weight gain was observed: an increase during the first 2 weeks and no additional weight gain (two patients) or minor weight loss (one patient) from weeks 3 to 6. None gained 7% of baseline weight, which is the cut-off for clinically significant weight gain. Betahistine was safe and well tolerated and did not interfere with the antipsychotic effect of olanzapine. Our findings justify a placebo-controlled evaluation of the putative weight-attenuating effect of betahistine in olanzapine-induced weight gain.

    Full Text Available Prior studies of appetite regulatory networks, primarily in rodents, have established that targeted electrical stimulation of ventromedial hypothalamus (VMH can alter food intake patterns and metabolic homeostasis. Consideration of this method for weight modulation in humans with severe overeating disorders and morbid obesity can be further advanced by modeling procedures and assessing endpoints that can provide preclinical data on efficacy and safety. In this study we adapted human deep brain stimulation (DBS stereotactic methods and instrumentation to demonstrate in a large animal model the modulation of weight gain with VMH-DBS. Female Göttingen minipigs were used because of their dietary habits, physiologic characteristics, and brain structures that resemble those of primates. Further, these animals become obese on extra-feeding regimens. DBS electrodes were first bilaterally implanted into the VMH of the animals (n = 8 which were then maintained on a restricted food regimen for 1 mo following the surgery. The daily amount of food was then doubled for the next 2 mo in all animals to produce obesity associated with extra calorie intake, with half of the animals (n = 4 concurrently receiving continuous low frequency (50 Hz VMH-DBS. Adverse motoric or behavioral effects were not observed subsequent to the surgical procedure or during the DBS period. Throughout this 2 mo DBS period, all animals consumed the doubled amount of daily food. However, the animals that had received VMH-DBS showed a cumulative weight gain (6.1±0.4 kg; mean ± SEM that was lower than the nonstimulated VMH-DBS animals (9.4±1.3 kg; p<0.05, suggestive of a DBS-associated increase in metabolic rate. These results in a porcine obesity model demonstrate the efficacy and behavioral safety of a low frequency VMH-DBS application as a potential clinical strategy for modulation of body weight.

    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.

    Full Text Available Objective. Excessive gestational weight gain (GWG is associated with adverse maternal and child outcomes and contributes to obesity in women. Our aim was to identify early pregnancy factors associated with excessive GWG, in a contemporary nulliparous cohort. Methods. Participants in the SCOPE study were classified into GWG categories (“not excessive” versus “excessive” based on pregravid body mass index (BMI using 2009 Institute of Medicine (IOM guidelines. Maternal characteristics and pregnancy risk factors at 14–16 weeks were compared between categories and multivariable analysis controlled for confounding factors. Results. Of 1950 women, 17% gained weight within the recommended range, 74% had excessive and 9% inadequate GWG. Women with excessive GWG were more likely to be overweight (adjOR 2.9 (95% CI 2.2–3.8 or obese (adjOR 2.5 (95% CI 1.8–3.5 before pregnancy compared to women with a normal BMI. Other factors independently associated with excessive GWG included recruitment in Ireland, younger maternal age, increasing maternal birthweight, cessation of smoking by 14–16 weeks, increased nightly sleep duration, high seafood diet, recent immigrant, limiting behaviour, and decreasing exercise by 14–16 weeks. Fertility treatment was protective. Conclusions. Identification of potentially modifiable risk factors for excessive GWG provides opportunities for intervention studies to improve pregnancy outcome and prevent maternal obesity.

METHODS: The weight and height/length of 409 preschool children at daycare centers were measured according to internationally recommended rules. The weight values and body mass indices of the children were transformed into a z-score per the standard method described by the World Health Organization. The Pearson correlation coefficients (rP and the linear regressions between the anthropometric parameters and the body mass index z-scores of preschool children were statistically analyzed (alpha = 0.05. RESULTS: The mean age of the study population was 3.2 years (± 0.3 years. The prevalence of excess weight was 28.8%, and the prevalence of overweight and obesity was 8.8%. The correlation coefficients between the body mass index z-scores of the preschool children and the birth weights or body mass indices at birth were low (0.09 and 0.10, respectively. There was a high correlation coefficient (rP = 0.79 between the mean monthly gain of weight and the body mass index z-score of preschool children. A higher coefficient (rP = 0.93 was observed between the ratio of the mean weight gain per height gain (g/cm and the preschool children body mass index z-score. The coefficients and their differences were statistically significant. CONCLUSION: Regardless of weight or length at birth, the mean ratio between the weight gain per g/cm of height growth from birth presented a strong correlation with the body mass index of preschool children. These results suggest that this ratio may be a good indicator of the risk of excess weight and obesity in preschool-aged children.

    Full Text Available Weight-gain in psychiatric populations is a common clinical challenge. Many patients suffering from mental disorders, when exposed to psychotropic medications, gain significant weight with or without other side-effects. In addition to reducing the patients′ willingness to comply with treatment, this weight-gain may create added psychological or physiological problems that need to be addressed. Thus, it is critical that clinicians take precautions to monitor and control weight-gain and take into account and treat all problems facing an individual. In this review, we examine some of the key issues surrounding weight-gain in individuals suffering from mental disorders for contemporary practitioners in community clinics. We describe some factors known to make certain patients more susceptible to treatment-induced weight-gain and mechanisms implicated in this process. We also highlight a few psychological and pharmacological interventions that have proven effective in weight management. Importantly, we provide critical steps for management and prevention of weight-gain and related issues in the clinical practice of psychopharmacology.

    Inadequate weight gain in pregnancy is a major contributor to low birth weight in Colorado, where the low birth weight rate is among the highest in the nation. In 2004, the Colorado Department of Public Health and Environment implemented a population-based intervention in 9 counties, including provider training and a public media campaign, to encourage pregnant women to gain an adequate amount of weight in pregnancy as defined by the 1990 Institute of Medicine guidelines. Pregnancy Risk Assessment Monitoring System survey data were used to track weight gain in pregnancy in 1997 through 2004 (baseline), 2005 (post-intervention), and 2006 and 2007 (after the intervention had concluded). During the period immediately after the implementation of the intervention, the percentage of women delivering in the 9 study counties who gained an inadequate amount of weight during pregnancy dropped from 18.4 at baseline to 12.8 in 2005. However, this progress was reversed in 2006, when the percentage of women with inadequate weight gain rose to 19.7. Training providers to educate women about the importance of adequate weight gain in pregnancy, in conjunction with a social marketing campaign, appears to be a promising approach to addressing a major contributor to low birth weight. However, a time-limited intervention is likely to have temporary results.

    The main aims of this study were to describe change in psychological outcomes for adolescents with anorexia nervosa across two treatments, and to explore predictors of change, including baseline demographic and clinical characteristics, as well as weight gain over time. Participants were 121 adolescents with anorexia nervosa from a two-site (Chicago and Stanford) randomized controlled trial who received either family-based treatment or individual adolescent supportive psychotherapy. Psychological symptoms (i.e., eating disorder psychopathology, depressive symptoms, and self-esteem) were assessed at baseline, end of treatment, 6-month, and 12-month follow-up. Conditional multilevel growth models were used to test for predictors of slope for each outcome. Most psychological symptoms improved significantly from baseline to 12 month follow-up, regardless of treatment type. Depressive symptoms and dietary restraint were most improved, weight and shape concerns were least improved, and self-esteem was not at all improved. Weight gain emerged as a significant predictor of improved eating disorder pathology, with earlier weight gain having a greater impact on symptom improvement than later weight gain. Adolescents who presented with more severe, complex, and enduring clinical presentations (i.e., longer duration of illness, greater eating disorder pathology, binge-eating/purging subtype) also appeared to benefit more psychologically from treatment.

    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.

    Second generation antipsychotics, like olanzapine (OLZ), have become the first line drug treatment for patients with schizophrenia. However, OLZ treatment is often associated with body weight (BW) gain and metabolic derangements. Therefore, the search for prospective markers for OLZ's negative side effects as well as adjunctive treatments to inhibit these has been of major interest. The aim of this study was to investigate in healthy male volunteers (age: 36 ± 11 years; BW: 84 ± 12 kg; BMI=25.5 ± 2.5) whether adjunctive topiramate (TPM) administration opposes OLZ-induced weight gain over the course of 14 days treatment. In addition, we investigated behavioral, endocrine and metabolic characteristics as underlying and potentially predictive factors for weight regulation and/or metabolic derangements associated with OLZ and TPM treatment. While adjunctive TPM indeed reduced OLZ-induced weight gain (PTPM. Using multiple regression analysis, BW gain was the key factor explaining metabolic disturbances (e.g., plasma insulin- LDL interaction: PTPM treatment, nor its circulating levels, contributed to variation observed in ΔBW. In a second multiple regression analysis, we observed that a low baseline thyrotropin profile (TSHAUC) before the start of drug treatment was associated with an increase in ΔBW over the course of drug treatment (PTPM treatment did attenuate OLZ induced BW gain (PTPM treatment blocking OLZ-induced ΔBW gain. Others have shown that OLZ-induced BW gain is associated with improvement in brief psychiatric rating scores (BPRS); adjunctive TPM treatment may be a solution specifically for those subjects susceptible to OLZ-induced rapid weight gain who-on a therapeutic level-benefit most of OLZ treatment.

    Objective To study the relations between different feeding patterns and the body weight retention of the perinatal women living in rural areas of China. Methods A cluster sampling method was used to investigate 409 women, who are currently living in rural areas of Tianjin, at pregnant and perinatal status. While, their body weights and heights before pregnancy, antepartum and postpartum were measured, respectively. Body weight retention was the difference of the measured data after postpartum minus pre-pregnant weight Varianee analysis was used for statistic comparison. Results The rate of exclusive breasffeeding was 70. 9% (290/409) within four months. The net body weight retention of women (5.8 kg) using the exclusive breasffeeding was lower than that of the women (7.0 kg) using artificial feeding within 4 - 6 months, but there was no significantly statistic difference (F = 1.45, P = 0. 236). However, there was the opposite result within 7 -9 months,the data showed that the body weight retention in the women using the exclusive breasffeeding was 4.9 kg, which was significantly higher than that the women (2.9 kg) with artificial feeding (F = 3. 17, P = 0. 043). The food consumption of the women (901 g) using exclusive breastfeeding was the highest,followed by those (877 g) using mixed feeding and the women (750 g) using artificial feeding. Conclusion The body weight retention after postpartum should be related to infant feeding patterns. After postpartum, the weight loss of women using the exclusive breasffeeding is relatively low. While,for the women using the exclusive breasffeeding,the net weight retention during pregnancy and after postpartum were lower than those with artificial feeding. Therefore, it is neeessary to enhance health edueation and guidance on promoting exclusive breast-feeding as well as increasing awareness on pre-pregnant health.%目的 了解农村妇女生育后喂养方式与体重滞留的关系.方法 采用整群抽样的方法 ,

    Full Text Available During pregnancy, many women gain excessive weight, which is related to adverse maternal and neonatal outcomes. In this study, we evaluated whether rate of gestational weight gain (RGWG in early, mid, and late pregnancy is strongly associated with adverse pregnancy outcomes. A retrospective chart review of 2,789 pregnant Korean women was performed. Weights were recorded at the first clinic visit, during the screening test for fetal anomaly, and during the 50g oral glucose challenge test and delivery, to represent early, mid, and late pregnancy, respectively. A multivariate logistic regression analysis was performed to examine the relationship between RGWG and adverse pregnancy outcomes. At early pregnancy, the RGWG was significantly associated with high risk of developing gestational diabetes mellitus (GDM, pregnancy-induced hypertension (PIH, large for gestational age (LGA infants, macrosomia, and primary cesarean section (P-CS. The RGWG of mid pregnancy was not significantly associated with any adverse pregnancy outcomes. The RGWG at late pregnancy was significantly associated with a lower risk of developing GDM, preterm birth and P-CS, but with a higher risk of developing LGA infants and macrosomia. When the subjects were divided into three groups (Underweight, Normal, and Obese, based on pre-pregnancy body mass index (BMI, the relationship between early RGWG and adverse pregnancy outcomes was significantly different across the three BMI groups. At early pregnancy, RGWG was not significantly associated to adverse pregnancy outcomes for subjects in the Underweight group. In the Normal group, however, early RGWG was significantly associated with GDM, PIH, LGA infants, macrosomia, P-CS, and small for gestational weight (SGA infants, whereas early RGWG was significantly associated with only a high risk of PIH in the Obese group. The results of our study suggest that early RGWG is significantly associated with various adverse pregnancy outcomes

    Full Text Available Antipsychotic drugs are widely used in treating schizophrenia, bipolar disorder, and other psychiatric disorders. Many of these drugs, despite their therapeutic advantages, substantially increase body weight. We assessed the association of alleles of 31 genes implicated in body weight regulation with weight gain among patients being treated with specific antipsychotic medications in the CATIE trial, we found that rs2237988 in ATP-binding cassette subfamily C member 8 (ABCC8 , and rs11643744 and rs9922047 in Fat Mass and Obesity Associated (FTO were associated with such weight gain.

    BACKGROUND: A diet with a high glycemic index (GI) and glycemic load (GL) may promote overconsumption of energy and increase the risk of weight gain. OBJECTIVE: The objective of the study was to investigate the relation between GI and GL of habitual diets and subsequent 6-y changes in body weight...... born in 1922, 1932, 1942, or 1952. A baseline health examination and a dietary history interview were carried out in 1987 and 1988; a follow-up health examination was performed in 1993 and 1994. RESULTS: Positive associations between GI and changes in body weight (DeltaBW), percentage body fat (Delta...... observed in men, and no significant associations with GL were observed in either sex. CONCLUSIONS: High-GI diets may lead to increases in BW, body fat mass, and WC in women, especially in sedentary women, which suggests that physical activity may protect against diet-induced weight gain. No associations...

    The purpose of this qualitative study was to explore perceptions and beliefs about body size, weight, and weight loss among obese African American women in order to form a design of weight loss intervention with this target population. Six focus groups were conducted at a community health clinic. Participants were predominantly middle-aged with a mean Body Mass Index of 40.3 +/- 9.2 kg/m(2). Findings suggest that participants (a) believe that people can be attractive and healthy at larger sizes; (b) still feel dissatisfied with their weight and self-conscious about their bodies; (c) emphasize eating behavior as the primary cause for weight gain; (d) view pregnancy, motherhood, and caregiving as major precursors to weight gain; (e) view health as the most important reason to lose weight; (f) have mixed experiences and expectations for social support for weight loss; and (g) prefer treatments that incorporate long-term lifestyle modification rather than fad diets or medication.

    Previous studies have established that higher birthweight is associated with increased risk of breast cancer. However, the mechanisms underlying this association remain unclear. We explored whether maternal pregnancy weight gain and pre-pregnancy body mass index (BMI), which influence birthweight, are associated with risk of breast cancer in offspring. The Nurses' Mothers case-control study of breast cancer was nested in the Nurses' Health Study I and II cohorts. Mothers of 814 nurses with and 1,809 nurses without breast cancer completed questionnaires with information on pre-pregnancy height and weight, pregnancy weight gain, and other aspects of their pregnancies with the nurse daughters. We calculated odds ratios for breast cancer using conditional logistic regression. Mean pregnancy weight gain was 23 lb, and average pre-pregnancy BMI was 21 kg/m². Mothers' weight gain during pregnancy was not associated with the daughters' risk of breast cancer. Compared to women whose mothers gained 20-29 lb, women whose mothers gained less than 10 lb had a relative risk of 0.92 (95% confidence interval [CI]: 0.62-1.36), adjusting for the age of the nurses. Women whose mothers gained 40 or more pounds had a relative risk of 0.82 (95% CI: 0.55-1.23). Mothers' pre-pregnancy BMI was not associated with the daughters' risk of breast cancer. Women whose mothers had a pre-pregnancy BMI of 30 or more had a relative risk of 0.77 (95% CI: 0.34-1.74) compared to those with BMI less than 20. Additional adjustment for prenatal factors or for nurses' characteristics later in life had no effect on the results. The association between birthweight and breast cancer risk is likely due to factors independent of mothers' weight gain during pregnancy or pre-pregnancy BMI. Because BMIs and pregnancy weight gains were lower in this population than today, we cannot rule out associations for very high pre-pregnancy BMIs or pregnancy weight gains.

    Full Text Available Abstract Background Identifying risk factors that affect excess weight gain during pregnancy is critical, especially among women who are at a higher risk for obesity. The goal of this study was to determine if acculturation, a possible risk factor, was associated with gestational weight gain in a predominantly Puerto Rican population. Methods We utilized data from Proyecto Buena Salud, a prospective cohort study of Hispanic women in Western Massachusetts, United States. Height, weight and gestational age were abstracted from medical records among participants with full-term pregnancies (n=952. Gestational weight gain was calculated as the difference between delivery and prepregnancy weight. Acculturation (measured via a psychological acculturation scale, generation in the US, place of birth and spoken language preference was assessed in early pregnancy. Results Adjusting for age, parity, perceived stress, gestational age, and prepregnancy weight, women who had at least one parent born in Puerto Rico/Dominican Republic (PR/DR and both grandparents born in PR/DR had a significantly higher mean total gestational weight gain (0.9 kg for at least one parent born in PR/DR and 2.2kg for grandparents born in PR/DR and rate of weight gain (0.03 kg/wk for at least one parent born in PR/DR and 0.06 kg/wk for grandparents born in PR/DR vs. women who were of PR/DR born. Similarly, women born in the US had significantly higher mean total gestational weight gain (1.0 kg and rate of weight gain (0.03 kg/wk vs. women who were PR/ DR born. Spoken language preference and psychological acculturation were not significantly associated with total or rate of pregnancy weight gain. Conclusion We found that psychological acculturation was not associated with gestational weight gain while place of birth and higher generation in the US were significantly associated with higher gestational weight gain. We interpret these findings to suggest the potential importance of the

    Full Text Available Abstract Background Women aged 25–45 years represent a high risk group for weight gain and those with children are at increased risk because of weight gain associated with pregnancy and subsequent lifestyle change. Average self-reported weight gain is approximately 0.60 kg per year, and weight gain is associated with increased risk of chronic disease. There are barriers to reaching, engaging and delivering lifestyle interventions to prevent weight gain in this population. Methods This study investigated the baseline weight related behaviors and feasibility of recruiting and delivering a low intensity self-management lifestyle intervention to community based women with children in order to prevent weight gain, compared to standard education. The recruitment and delivery of the cluster-randomized controlled intervention was in conjunction with 12 primary (elementary schools. Baseline data collection included demographic, anthropometric, behavioral and biological measures. Results Two hundred and fifty community based women were randomized as clusters to intervention (n = 127 or control (n = 123. Mean age was 40.4 years (SD 4.7 and mean BMI 27.8 kg/m2 (SD 5.6. All components of this intervention were successfully delivered and retention rates were excellent, 97% at 4 months. Nearly all women (90% reported being dissatisfied with their weight and 72% attempted to self-manage their weight. Women were more confident of changing their diet (mean score 3.2 than physical activity (mean score 2.7. This population perceived they were engaging in prevention behaviors, with 71% reporting actively trying to prevent weight gain, yet they consumed a mean of 68 g fat/day (SD30 g and 27 g saturated fat/day (SD12 g representing 32% and 13% of energy respectively. The women had a high rate of dyslipidemia (33% and engaged in an average of 9187 steps/day (SD 3671.

    To investigate the relationship among parity, length of the inter-pregnancy intervals and excessive pregnancy weight gain in the first pregnancy and the risk of obesity. Using a prospective cohort study of 3,422 non-obese, non-pregnant US women aged 14-22 years at baseline, adjusted Cox models were used to estimate the association among parity, inter-pregnancy intervals, and excessive pregnancy weight gain in the first pregnancy and the relative hazard rate (HR) of obesity. Compared to nulliparous women, primiparous women with excessive pregnancy weight gain in the first pregnancy had a HR of obesity of 1.79 (95% CI 1.40, 2.29); no significant difference was seen between primiparous without excessive pregnancy weight gain in the first pregnancy and nulliparous women. Among women with the same pregnancy weight gain in the first pregnancy and the same number of inter-pregnancy intervals (12 and 18 months or ≥18 months), the HR of obesity increased 2.43-fold (95% CI 1.21, 4.89; p = 0.01) for every additional inter-pregnancy interval of pregnancy intervals. Among women with the same parity and inter-pregnancy interval pattern, women with excessive pregnancy weight gain in the first pregnancy had an HR of obesity 2.41 times higher (95% CI 1.81, 3.21; p obesity risk unless the primiparous women had excessive pregnancy weight gain in the first pregnancy, then their risk of obesity was greater. Multiparous women with the same excessive pregnancy weight gain in the first pregnancy and at least one additional short inter-pregnancy interval had a significant risk of obesity after childbirth. Perinatal interventions that prevent excessive pregnancy weight gain in the first pregnancy or lengthen the inter-pregnancy interval are necessary for reducing maternal obesity.

    Full Text Available Antipsychotic induced weight gain is the most common and distressing side effect. This also affects the compliance toward the treatment and hence the prognosis. Non - pharmacological interventions such as exercise and diet modifications alone might not be sufficient most of the times; also ensuring compliance toward this is difficult in patients with psychiatric illness. So, the role of weight - reducing drugs become important. In this case report, we describe the use of low - dose topiramate as a weight - reducing agent, in a patient with a bipolar affective disorder - mania with psychotic symptoms, who had significant risperidone - induced weight gain.

    Repeated attempts to lose weight by temporary dieting may result in weight cycling, eventually further gain of body fat, and possible metabolic adaptation. We tested this with a controlled experiment in C57BL/6J mice subjected to four weight cycles (WC), continuous hypercaloric feeding (HF), or low-fat feeding (LF). To search for genes involved in an adaptive mechanism to former weight cycling and avoid acute effects of the last cycle, the last hypercaloric feeding period was prolonged by an additional 2 wk before euthanization. Total energy intake was identical in WC and HF. However, compared with HF, the WC mice gained significantly more total body mass and fat mass and showed increased levels of circulating leptin and lipids in liver. Both the HF and WC groups showed increased adipocyte size and insulin resistance. Despite these effects, we also observed an interesting maintenance of circulating adiponectin and free fatty acid levels after WC, whereas changes in these parameters were observed in HF mice. Global gene expression was analyzed by microarrays. Weight-cycled mice were characterized by a downregulation of several clock genes (Dbp, Tef, Per1, Per2, Per3, and Nr1d2) in adipose tissues, which was confirmed by quantitative PCR. In 3T3-L1 cells, we found reduced expression of Dbp and Tef early in adipogenic differentiation, which was mediated via cAMP-dependent signaling. Our data suggest that clock genes in adipose tissue may play a role in metabolic adaptation to weight cycling.

    Full Text Available Tessa JM Wallace, Clement C Zai, Eva J Brandl, Daniel J MüllerNeurogenetics Section, Center for Addiction and Mental Health, Department of Psychiatry, University of Toronto, Toronto, ON, CanadaAbstract: Antipsychotic-induced weight gain is a serious side effect of antipsychotic medication that can lead to increased morbidity, mortality, and non-compliance in patients. Numerous single nucleotide polymorphisms have been studied for association with antipsychotic-induced weight gain in an attempt to find genetic predictors of this side effect. An ability to predict this side effect could lead to personalized treatment plans for predisposed individuals, which could significantly decrease the prevalence and severity of weight gain. Variations in the serotonin receptor 2c gene (HTR2C have emerged as promising candidates for prediction of antipsychotic-induced weight gain. Specifically, the well-studied -759C/T promoter polymorphism has been associated with weight gain in diverse populations, although some studies have reported no association. This discrepancy is likely due to heterogeneity in study design with respect to ethnicity, treatment duration, and other variables. Notably, the association between HTR2C and antipsychotic-induced weight gain appears strongest in short-term studies on patients with limited or no previous antipsychotic treatment. Other, less extensively studied promoter polymorphisms (-697C/G, -997G/A, and -1165A/G have also emerged as potential predictors of antipsychotic-induced weight gain. Conversely, the well-studied intronic polymorphism Cys23Ser does not appear to be associated. With further research on both HTR2C and other genetic and environmental predictors of antipsychotic-induced weight gain, a predictive test could one day be created to screen patients and provide preventative or alternative treatment for those who are predisposed to this serious side effect.Keywords: HTR2C, pharmacogenomics, promoter polymorphism

    Abstract Background Maternal feeding practices have been proposed to play an important role in early child weight gain and obesogenic eating behaviors. However, to date longitudinal investigations in young children exploring these relationships have been lacking. The aim of the present study was to explore prospective relationships between maternal feeding practices, child weight gain and obesogenic eating behaviors in 2-year-old children.

  4. Novel regulator of acylated ghrelin, CF801, reduces weight gain, rebound feeding after a fast, and adiposity in mice

    2015-09-01

    Full Text Available Ghrelin is a 28 amino-acid hormonal peptide that is intimately related to the regulation of food intake and body weight. Once secreted, ghrelin binds to the growth hormone secretagogue receptor-1a (GHSR-1a, the only known receptor for ghrelin and is capable of activating a number of signaling cascades ultimately resulting in an increase in food intake and adiposity. Because ghrelin has been linked to overeating and the development of obesity, a number of pharmacological interventions have been generated in order to interfere with either the activation of ghrelin or interrupting ghrelin signaling as a means to reducing appetite and decrease weight gain. Here we present a novel peptide, CF801, capable of reducing circulating acylated ghrelin levels and subsequent body weight gain and adiposity. To this end, we show that IP administration of CF801 is sufficient to reduce circulating plasma acylated ghrelin levels. Acutely, intraperitoneal injections of CF801 resulted in decreased rebound feeding after an overnight fast. When delivered chronically decreased weight gain and adiposity without affecting caloric intake. CF801, however, did cause a change in diet preference, decreasing preference for a high fat diet and increasing preference for regular chow diet. Given the complexity of ghrelin receptor function, we propose that CF801 along with other compounds that regulate ghrelin secretion may prove to be a beneficial tool in the study of the ghrelin system, and potential targets for ghrelin based obesity treatments without altering the function of ghrelin receptors.

    Dairy products have previously been reported to be associated with beneficial effects on body weight and metabolic risk markers. Moreover, primary data from the Diet, Obesity and Genes (DiOGenes) study indicate a weight-maintaining effect of a high-protein-low-glycaemic index diet. The objective of the present study was to examine putative associations between consumption of dairy proteins and changes in body weight and metabolic risk markers after weight loss in obese and overweight adults. Results were based on secondary analyses of data obtained from overweight and obese adults who completed the DiOGenes study. The study consisted of an 8-week weight-loss phase and a 6-month weight-maintenance (WM) phase, where the subjects were given five different diets varying in protein content and glycaemic index. In the present study, data obtained from all the subjects were pooled. Dairy protein intake was estimated from 3 d dietary records at two time points (week 4 and week 26) during the WM phase. Body weight and metabolic risk markers were determined at baseline (week -9 to -11) and before and at the end of the WM phase (week 0 and week 26). Overall, no significant associations were found between consumption of dairy proteins and changes in body weight and metabolic risk markers. However, dairy protein intake tended to be negatively associated with body weight gain (P=0·08; β=-0·17), but this was not persistent when controlled for total protein intake, which indicates that dairy protein adds no additional effect to the effect of total protein. Therefore, the present study does not report that dairy proteins are more favourable than other proteins for body weight regulation.

    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.

    Excessive gestational weight gain (GWG) is associated with complications for both mother and child. Minority women are at increased risk for excessive GWG, yet are underrepresented in published weight control interventions. To inform future interventions, we examined the prevalence and accuracy of provider advice and its association with personal beliefs about necessary maternal weight gain among predominantly Latina pregnant women. Secondary analysis examining baseline data (N = 123) from a healthy lifestyle randomized controlled trial conducted in and urban area of the South East. Only 23.6 % of women reported being told how much weight to gain during pregnancy; although 58.6 % received advice that met Institute of Medicine recommendations. Concordance of mothers' personal weight gain target with clinical recommendations varied by mothers' pre-pregnancy weight status [χ (4) (2)  = 9.781, p = 0.044]. Findings suggest the need for prenatal providers of low-income, minority women to engage patients in shaping healthy weight gain targets as a precursor to preventing excessive GWG and its complications.

    Prematurity and poor weight gaining are important causes for neonatal hospitalization. The present study aimed to investigate the role of medium-chain triglyceride (MCT) oil via massage therapy as a supplementary nutritional method on the weight gain of Neonatal Intensive Care Units (NICU)-hospitalized neonates. This randomized clinical trial performed among 121 stable premature neonates hospitalized in the NICU of Qaem Educational Hospital, Mashhad, Iran. They were randomly divided into three groups: oil-massage, massage alone and control groups. These groups were compared on the basis of weight gain during a one-week interval. The three groups were matched for sex, mean gestational age, birth weight, head circumference, delivery, and feeding type (P>0.05). The mean weight gain on the 7th day in the oil massage group was 105±1.3gr and 52±0.1gr in the massage group; whereas 54±1.3gr weight loss was observed in the control group. Significant differences were observed between the oil-massage group and the other two groups, respectively (P=0.002 and P=0.000). The findings of this study suggest that transcutaneous feeding with MCT oil massage therapy in premature neonates can result in accelerated weight gain in this age group with no risk of NEC.

Methods: Randomized clinical trial with 61 premature infants, of both sexes, with postconceptional age greater or equal to 32 weeks and at least ten days of life, without detected abnormalities in the visual and hearing systems, and hospitalized in the Kangaroo-Mother Unit. Patients were randomized in two groups: of 31 preterm infants received multimodal stimulation with music daily, for seven days; 30 preterm infants received only multimodal stimulation. The following characteristics were evaluated: weight gain, energy consumption, heart rate and respiratory rate, stress signs and feeding method. Comparison between groups was made by Student’s t-test, Mann Whitney test and chi-square test, being significant p<0.05. Results: The two groups did not present significant differences in relation to the feeding method and energy consumption (p=0.46; however, weight gain was greater in the Experimental Group (p=0.002, which also presented better stability in cardiac and respiratory rates (p<0.001 and a significant reduction of stress signs (p=0.007, compared with the Control Group. Conclusions: The recorded music with multimodal stimulation is associated with a greater gain in body weight of hospitalized preterm infants as well as presents a positive influence on vital and stress signs (Clinical Trials Registry - UTN: U1111-1153-9301.

  12. Are breaks in daily self-weighing associated with weight gain?

    Directory of Open Access Journals (Sweden)

    Elina E Helander

    Full Text Available Regular self-weighing is linked to successful weight loss and maintenance. However, an individual's self-weighing frequency typically varies over time. This study examined temporal associations between time differences of consecutive weight measurements and the corresponding weight changes by analysing longitudinal self-weighing data, including 2,838 weight observations from 40 individuals attending a health-promoting programme. The relationship between temporal weighing frequency and corresponding weight change was studied primarily using a linear mixed effects model. Weight change between consecutive weight measurements was associated with the corresponding time difference (β = 0.021% per day, p<0.001. Weight loss took place during periods of daily self-weighing, whereas breaks longer than one month posed a risk of weight gain. The findings emphasize that missing data in weight management studies with a weight-monitoring component may be associated with non-adherence to the weight loss programme and an early sign of weight gain.

    Obesity has been associated with increased cardiac sympathetic activation during wakefulness, but the effect on sleep-related sympathetic modulation is not known. The aim of this study was to investigate the effect of fat gain on cardiac autonomic control during wakefulness and sleep in humans. We performed a randomized controlled study to assess the effects of fat gain on heart rate variability (HRV). We recruited 36 healthy volunteers, who were randomized to either a standardized diet to gain approximately 4 kg over 8 weeks followed by an 8 week weight loss period (n=20), or to serve as a weight-maintainer control (n=16). An overnight polysomnogram with power spectral analysis of HRV was performed at baseline, after weight gain, and after weight loss to determine the ratio of low frequency (LF) to high frequency (HF) power, and to examine the relationship between changes in HRV and changes in insulin, leptin and adiponectin levels. Mean weight gain was 3.9 kg in the fat gain group versus 0.1 kg in the maintainer group. LF/HF increased both during wakefulness and sleep after fat gain and returned to baseline after fat loss in the fat gain group, and did not change in the control group. Insulin, leptin and adiponectin also increased after fat gain and fell after fat loss, but no clear pattern of changes were seen that correlated consistently with changes in HRV. Short-term fat gain in healthy subjects is associated with increased cardiac sympathetic activation during wakefulness and sleep but the mechanisms remain unclear. PMID:21357280

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.

    Second-generation antipsychotics (SGAs), valproate, and sulpiride are related to significant weight gain and risk of metabolic syndrome (MetS). Among SGAs, olanzapine and clozapine are associated with the highest metabolic risk while ziprasidone is among one of the SGAs with the lowest risk. Several reports suggest that weight loss is observed in switching other antipsychotics to ziprasidone. Here we describe a female patient with chronic paranoid schizophrenia who had an unexpected weight gain and developed MetS during a cross-switch from a polypharmacy of olanzapine, valproate and sulpiride to ziprasidone monotherapy.

    AIM: To examine the effects of long-term proton pump inhibitor (PPI) therapy on body weight (BW) and body mass index (BMI) in patients with gastroesophageal reflux disease (GERD). METHODS: The subjects were 52 patients with GERD and 58 sex- and age-matched healthy controls. GERD patients were treated with PPI for a mean of 2.2 years (range, 0.8-5.7 years), and also advised on lifestyle modifications (e.g. selective diet, weight management). BW, BMI and other parameters were measured at baseline and end of study. RESULTS: Twenty-four GERD patients were treated daily with 10 mg omeprazole, 12 with 20 mg omeprazole, 8 with 10 mg rabeprazole, 5 with 15 mg lansoprazole, and 3 patients with 30 mg lansoprazole. At baseline, there were no differences in BW and BMI between reflux patients and controls. Patients with GERD showed increases in BW (baseline: 56.4 ± 10.4 kg, end: 58.6 ± 10.8 kg, mean ± SD, P < 0.0001) and BMI (baseline: 23.1 ± 3.1 kg/m~2, end: 24.0 ± 3.1 kg/m~2, P < 0.001), but no such changes were noted in the control group. Mean BW increased by 3.5 kg (6.2% of baseline) in 37 (71%) reflux patients but decreased in only 6 (12%) patients during treatment. CONCLUSION: Long-term PPI treatment was associated with BW gain in patients with GERD. Reflux patients receiving PPI should be encouraged to manage BW through lifestyle modifications.

  6. Control of body weight by eating behavior in children

    2015-10-01

    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.

  8. Control of Body Weight by Eating Behavior in Children

    OpenAIRE

    2015-01-01

    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 ...

    We compared obstetric outcomes based on gestational weight gain in normal-weight and obese women using traditional Institute of Medicine (IOM) guidelines and newly recommended Cedergren criteria. Using the New Jersey Pregnancy Risk Assessment Monitoring System (PRAMS) database and electronic birth records, perinatal outcomes were analyzed to estimate the independent effects of prepregnancy body mass index (BMI) and gestational weight gain by IOM versus Cedergren criteria. Of 9125 subjects in PRAMS database from 2002 to 2006, 53.7% had normal BMI, 12.3% were overweight, 18.2% were obese, and the rest were underweight. Among normal-weight mothers, when compared with the IOM guidelines, macrosomia (6.45% versus 4.27%) and cesarean delivery rates (30.42% versus 29.83%) were lower using Cedergren criteria but the rates of preterm delivery (5.06% versus 9.44%), low birth weight (0.38% versus 2.42%), and neonatal intensive care unit (NICU) admissions (7.02% versus 10.86%) were higher with the Cedergren criteria. Similarly, among obese patients, when compared with IOM guidelines, macrosomia (10.79% versus 5.47%) and cesarean delivery rates (43.95% versus 40.71%) were lower using Cedergren criteria but the rates of preterm delivery (6.83% versus 8.32%), low birth weight (0.87% versus 1.88%), and NICU admissions (8.92% versus 13.78%) were higher with the Cedergren criteria. Based on our results, ideal gestational weight gain is presumably somewhere between the IOM and Cedergren's guidelines.

  11. Preventing olanzapine-induced weight gain using betahistine: a study in a rat model with chronic olanzapine treatment.

    Full Text Available Olanzapine is the one of first line antipsychotic drug for schizophrenia and other serious mental illness. However, it is associated with troublesome metabolic side-effects, particularly body weight gain and obesity. The antagonistic affinity to histamine H1 receptors (H1R of antipsychotic drugs has been identified as one of the main contributors to weight gain/obesity side-effects. Our previous study showed that a short term (2 weeks combination treatment of betahistine (an H1R agonist and H3R antagonist and olanzapine (O+B reduced (-45% body weight gain induced by olanzapine in drug-naïve rats. A key issue is that clinical patients suffering with schizophrenia, bipolar disease and other mental disorders often face chronic, even life-time, antipsychotic treatment, in which they have often had previous antipsychotic exposure. Therefore, we investigated the effects of chronic O+B co-treatment in controlling body weight in female rats with chronic and repeated exposure of olanzapine. The results showed that co-administration of olanzapine (3 mg/kg, t.i.d. and betahistine (9.6 mg/kg, t.i.d. significantly reduced (-51.4% weight gain induced by olanzapine. Co-treatment of O+B also led to a decrease in feeding efficiency, liver and fat mass. Consistently, the olanzapine-only treatment increased hypothalamic H1R protein levels, as well as hypothalamic pAMPKα, AMPKα and NPY protein levels, while reducing the hypothalamic POMC, and UCP1 and PGC-1α protein levels in brown adipose tissue (BAT. The olanzapine induced changes in hypothalamic H1R, pAMPKα, BAT UCP1 and PGC-1α could be reversed by co-treatment of O+B. These results supported further clinical trials to test the effectiveness of co-treatment of O+B for controlling weight gain/obesity side-effects in schizophrenia with chronic antipsychotic treatment.

  12. Electrical vagus nerve stimulation decreases food consumption and weight gain in rats fed a high-fat diet.

    There is growing evidence that vagus nerve stimulation (VNS) has a suppressive effect on both short- and long-term feeding in animal models. We previously showed that long-term VNS (102 days) with low-frequency electrical impulses (0.05 Hz) decreased food intake and body weight in rats. In the present study, we investigated the effect of high frequency (10 Hz) VNS on feeding behavior and appetite in rats fed a high-fat diet; peptide secretion and other parameters were assessed as well. Adult male Wistar rats were each implanted subcutaneously with a microstimulator (MS) and fed a high-fat diet throughout the entire study period (42 days). The left vagus nerve was stimulated by rectangular electrical pulses (10 ms, 200 mV, 10 Hz, 12 h a day) generated by the MS. Body weight and food intake were measured each morning. At the end of the experimental period, animals were euthanized and blood samples were taken. Serum levels of ghrelin, leptin and nesfatin-1 were assessed using radioimmunoassays. Adipose tissue content was evaluated by weighing epididymal fat pads, which were incised at the time of sacrifice. To determine whether VNS activated the food-related areas of the brain, neuronal c-Fos induction in the nuclei of the solitary tract (NTS) was assessed. Chronic vagus nerve stimulation significantly decreased food intake, body weight gain and epididymal fat pad weight in animals that received VNS compared with control animals. Significant neuronal responses in the NTS were observed following VNS. Finally, serum concentrations of ghrelin were increased, while serum levels of leptin were decreased. Although not significant, serum nesfatin-1 levels were also elevated. These results support the theory that VNS leads to reductions in food intake, body weight gain and adipose tissue by increasing brain satiety signals conducted through the vagal afferents. VNS also evoked a feed-related hormonal response, including elevated blood concentrations of nesfatin-1.

    The objective of this study was to estimate whether maternal history of childhood maltreatment was associated with pre-pregnancy obesity or excessive gestational weight gain. Pregnant women (n = 472) reported pre-pregnancy weight and height and gestational weight gain and were followed up to 16 years post-partum when they reported maltreatment on the Childhood Trauma Questionnaire (CTQ). CTQ score ranged from no maltreatment (25) to severe maltreatment (125). Prenatal mental health modified the association between CTQ score and maternal weight (P alcohol use, a one standard deviation (1 SD) increase in CTQ score was associated with a 45% increase in the risk of pre-pregnancy obesity among the 141 women with elevated anxiety (≥75th percentile on the State Trait Anxiety Inventory) [relative risk, RR (95% confidence interval, CI): 1.45 (1.12, 1.88)], but was not associated among less anxious (maltreatment and weight gain. Factors such as psychological status and traumatic experiences in early childhood may contribute to pre-pregnancy obesity and excessive gestational weight gain.

    This study examined differences in gestational weight gain for women in CenteringPregnancy (CP) group prenatal care versus individually delivered prenatal care. We conducted a retrospective chart review and used propensity scores to form a matched sample of 393 women (76 % African-American, 13 % Latina, 11 % White; average age 22 years) receiving prenatal care at a community health center in the South. Women were matched on a wide range of demographic and medical background characteristics. Compared to the matched group of women receiving standard individual prenatal care, CP participants were less likely to have excessive gestational weight gain, regardless of their pre-pregnancy weight (b = -.99, 95 % CI [-1.92, -.06], RRR = .37). CP reduced the risk of excessive weight gain during pregnancy to 54 % of what it would have been in the standard model of prenatal care (NNT = 5). The beneficial effect of CP was largest for women who were overweight or obese prior to their pregnancy. Effects did not vary by gestational age at delivery. Post-hoc analyses provided no evidence of adverse effects on newborn birth weight outcomes. Group prenatal care had statistically and clinically significant beneficial effects on reducing excessive gestational weight gain relative to traditional individual prenatal care.

    Introduction Diverse factors influence an individual’s ability to successfully achieve and maintain energy balance consistent with a healthy body weight. Eating frequency is one among the varied feature that thought to have a direct impact on the body weight gain. Aim The present cross-sectional study has been carried out with the intention of awareness of food habit that specifically emphasize the frequency of eating and its effect on weight gain of an individual. Materials and Methods This cross-sectional study involved 265 medical undergraduate students. Faculty validated close ended questionnaire was distributed to the students and the responses given by them were then analysed. Statistical evaluation of data with Spearman correlation coefficient (r) was done. Results Among the total 265 participants, 177 (66.8%) were noted to have normal Body Mass Index (BMI 18.5-24.9). Out of them, 113 (64%) found to have eating frequency 3-4 meals/day, 44 (25%) with 1-2 meals/day, 18 (10%) with 5-6 meals/day and 2 (1%) with more than 6 meals/day. Low positive correlation (r=0.09) between mean frequency of eating and the number of subjects with normal BMI was observed. Conclusion An increase in the eating frequency can also be correlated with an increased prevalence of normal BMI individuals provided adequate physical exercise.

    Full Text Available Objective. Compared with other insulin analogues, insulin detemir induces less weight gain. This study investigated whether this effect was achieved by influencing the hypothalamic appetite regulators neuropeptide Y (NPY and galanin (GAL. Methods. Type  2 diabetic rat models were established with a high-fat diet and intraperitoneal injection of STZ. All rats were divided into NC, DM, DM+DE and DM+GLA groups. Glycemic levels of all study groups were checked at study onset and after 4 weeks of insulin treatment. Food intake and body weight were monitored during treatment. After 4 weeks, the hypothalamus of rats was examined for NPY and GAL mRNA and protein expression. Results. After 4 weeks of treatment, compared with the DM+GLA group, the DM+DE group exhibited less food intake (P<0.05 and less weight gain (P<0.05, but showed similar glycemic control. The expression of hypothalamic NPY and GAL at both mRNA and protein level were significantly lower (P<0.05 in the DM+DE group. Conclusion. Insulin detemir decreased food intake in type 2 diabetic rats, which led to reduced weight gain when compared to insulin glargine treatment. This effect is likely due to downregulation of hypothalamic NPY and GAL.

    Full Text Available OBJECTIVES: Seeds are excellent sources of proteinase inhibitors, some of which may have satietogenic and slimming actions. We evaluated the effect of a trypsin inhibitor from Tamarindus indica L. seeds on weight gain, food consumption and cholecystokinin levels in Wistar rats. METHODS: A trypsin inhibitor from Tamarindus was isolated using ammonium sulfate (30-60% following precipitation with acetone and was further isolated with Trypsin-Sepharose affinity chromatography. Analyses were conducted to assess the in vivo digestibility, food intake, body weight evolution and cholecystokinin levels in Wistar rats. Histological analyses of organs and biochemical analyses of sera were performed. RESULTS: The trypsin inhibitor from Tamarindus reduced food consumption, thereby reducing weight gain. The in vivo true digestibility was not significantly different between the control and Tamarindus trypsin inhibitor-treated groups. The trypsin inhibitor from Tamarindus did not cause alterations in biochemical parameters or liver, stomach, intestine or pancreas histology. Rats treated with the trypsin inhibitor showed significantly elevated cholecystokinin levels compared with animals receiving casein or water. CONCLUSION: The results indicate that the isolated trypsin inhibitor from Tamarindus reduces weight gain by reducing food consumption, an effect that may be mediated by increased cholecystokinin. Thus, the potential use of this trypsin inhibitor in obesity prevention and/or treatment should be evaluated.

  19. The antipsychotic olanzapine interacts with the gut microbiome to cause weight gain in mouse.

    Directory of Open Access Journals (Sweden)

    Andrew P Morgan

    Full Text Available The second-generation antipsychotic olanzapine is effective in reducing psychotic symptoms but can cause extreme weight gain in human patients. We investigated the role of the gut microbiota in this adverse drug effect using a mouse model. First, we used germ-free C57BL/6J mice to demonstrate that gut bacteria are necessary and sufficient for weight gain caused by oral delivery of olanzapine. Second, we surveyed fecal microbiota before, during, and after treatment and found that olanzapine potentiated a shift towards an "obesogenic" bacterial profile. Finally, we demonstrated that olanzapine has antimicrobial activity in vitro against resident enteric bacterial strains. These results collectively provide strong evidence for a mechanism underlying olanzapine-induced weight gain in mouse and a hypothesis for clinical translation in human patients.

    Obesity is a major public health concern. In western countries, the prevalence of obesity in pregnant women has strongly increased, with reported prevalence rates reaching 30%. Also, up to 40% of women gain an excessive amount of weight during pregnancy. Recent observational studies and meta-analyses strongly suggest long-term impact of maternal obesity and excessive weight gain during pregnancy on adiposity, cardiovascular and respiratory related health outcomes in their children. These observations suggest that maternal adiposity during pregnancy may program common health problems in the offspring. Currently, it remains unclear whether the observed associations are causal, or just reflect confounding by family-based sociodemographic or lifestyle-related factors. Parent-offspring studies, sibling comparison studies, Mendelian randomization studies and randomized trials can help to explore the causality and underlying mechanisms. Also, the potential for prevention of common diseases in future generations by reducing maternal obesity and excessive weight gain during pregnancy needs to be explored.

  2. Compensatory weight gain due to dopaminergic hypofunction: new evidence and own incidental observations

    2008-12-01

    Full Text Available Abstract There is increasing evidence for a role of dopamine in the development of obesity. More specifically, dopaminergic hypofunction might lead to (overcompensatory food intake. Overeating and resulting weight gain may be induced by genetic predisposition for lower dopaminergic activity, but might also be a behavioral mechanism of compensating for decreased dopamine signaling after dopaminergic overstimulation, for example after smoking cessation or overconsumption of high palatable food. This hypothesis is in line with our incidental finding of increased weight gain after discontinuation of pharmaceutical dopaminergic overstimulation in rats. These findings support the crucial role of dopaminergic signaling for eating behaviors and offer an explanation for weight-gain after cessation of activities associated with high dopaminergic signaling. They further support the possibility that dopaminergic medication could be used to moderate food intake.

    Full Text Available Objective. To determine the effectiveness of exercise and/or nutrition interventions and to address body weight changes during the menopause transition. Methods. A systematic review of the literature was conducted using electronic databases, grey literature, and hand searching. Two independent researchers screened for studies using experimental designs to evaluate the impact of exercise and/or nutrition interventions on body weight and/or central weight gain performed during the menopausal transition. Studies were quality appraised using Cochrane risk of bias. Included studies were analyzed descriptively. Results. Of 3,564 unique citations screened, 3 studies were eligible (2 randomized controlled trials, and 1 pre/post study. Study quality ranged from low to high risk of bias. One randomized controlled trial with lower risk of bias concluded that participation in an exercise program combined with dietary interventions might mitigate body adiposity increases, which is normally observed during the menopause transition. The other two studies with higher risk of bias suggested that exercise might attenuate weight loss or weight gain and change abdominal adiposity patterns. Conclusions. High quality studies evaluating the effectiveness of interventions targeting body weight changes in women during their menopause transition are needed. Evidence from one higher quality study indicates an effective multifaceted intervention for women to minimize changes in body adiposity.

  6. Toward a quantitative theory of food consumption choices and body weight.

    Science.gov (United States)

    Buttet, Sebastien; Dolar, Veronika

    2015-04-01

    We propose a calibrated dynamic model of food consumption choices and body weight to study changes in daily caloric intake, weight, and the away-from-home share of calories consumed by adult men and women in the U.S. during the period between 1971 and 2006. Calibration reveals substantial preference heterogeneity between men and women. For example, utility losses stemming from weight gains are ten times greater for women compared to men. Counterfactual experiments show that changes in food prices and household income account for half of the increase in weight of adult men, but only a small fraction of women's weight. We argue that quantitative models of food consumption choices and body weight have a unique role to play in future research in the economics of obesity.

    Over 30% of youth and adolescents have overweight or obesity, and health care providers are increasingly discussing weight-based health with these patients. Stigmatizing language in provider-patient communication about obesity is well documented and could be particularly detrimental to youth and adolescents. Although some research has examined preferences for weight-based terminology among adults, no studies have addressed these issues in youth populations. This study represents a preliminary and systematic investigation of weight-based language preferences among adolescents with overweight and obesity enrolled in a summer weight loss camp. Participants (N=50) indicated preferences for weight-based language and emotional responses to words that their family members used in reference to their body weight. Weight neutral terminology ('weight', 'body mass index') were most preferred, although some differences in word preferences emerged by the participants' gender. Boys preferred having their weight described as 'overweight' and 'heavy', while girls preferred the word 'curvy'. A large proportion of participants, particularly girls, reported experiencing sadness, shame, and embarrassment if parents used certain words to describe their body weight, which highlights the importance of considering the emotional impact of weight-based terminology. Providers may consider asking youth and adolescents for their preferences when discussing weight-based health.International Journal of Obesity advance online publication, 4 April 2017; doi:10.1038/ijo.2017.55.

  8. Daily Self-Weighing to Control Body Weight in Adults

    2014-12-01

    Full Text Available The objective of this study is to review the history of daily self-weighing for weight control, discuss the possibility that self-weighing may cause adverse psychological symptoms, and propose mechanisms that explain how self-weighing facilitates weight control. A systematic forward (citation tracking approach has been employed in this study. In the early literature, experimental tests did not demonstrate a benefit of adding daily self-weighing to traditional behavioral modification for weight loss. More recent studies have shown that daily self-weighing combined with personalized electronic feedback can produce and sustain weight loss with and without a traditional weight loss program. Daily self-weighing appears to be effective in preventing age-related weight gain. Apart from these experimental findings, there is considerable agreement that the frequency of self-weighing correlates with success in losing weight and sustaining the weight loss. The early literature suggested frequent self-weighing may be associated with negative psychological effects. However, more recent experimental trials do not substantiate such a causal relationship. In conclusion, daily self-weighing may be a useful strategy for certain adults to prevent weight gain, lose weight, or prevent weight regain after loss. More research is needed to better understand the role of different types of feedback, who benefits most from self-weighing, and at what frequency.

  9. Pregnancy weight gain and postpartum loss: avoiding obesity while optimizing the growth and development of the fetus.

    Lederman, S A

    2001-01-01

    Weight gain during pregnancy may contribute to obesity development. Concerns about possible adverse effects of pregnancy weight gain on later maternal weight and on labor and delivery must be rigorously evaluated in light of possible benefits for fetal growth and development. Birth-weight rises with increased pregnancy weight gain, and perinatal and neonatal mortality fall as birthweight increases in both preterm and term infants. The lowest mortality is observed at 3500 to 4500 g in infants of white women. Although often thought to be at high risk, infants termed "macrosomic" include infants of the lowest mortality rate. Thus, restricting weight gain may be detrimental to the baby. Weight gain that is optimal for the mother and the baby differs according to the mother's prepregnancy weight. Pregnancy weight gain exceeding current recommendations is associated with increases in maternal fat gain, pregnancy complications, and delivery problems and should be discouraged. Postpartum weight loss is essential to prevent permanent weight increase. Smoking cessation during pregnancy, reduced postpartum physical activity, and other lifestyle changes can contribute to increased postpartum weight. Health care providers can help to reduce obesity risk by regularly monitoring women's weight; promoting appropriate prepregnancy weight, pregnancy weight gain, and postpartum weight less; and explicitly encouraging maintenance of an active postpartum lifestyle.

    Full Text Available Live weights and 21 body measurements of 110 adult brood mares from Thoroughbred breed were evaluated in Hungary. Body measurements and some body measure indices were determined. One way ANOVA was used to compare the studs. Regression equations were developed to estimate the live weight from body measurements. Population genetic parameters of the examined traits were estimated. Only few differences among studs, concerning evaluated body measurements, were presented - firstly: body measurements, related to the kilter and nutritional status (hearth girth - were significant. Between the mentioned traits and the live weight medium positive correlation (r = 0.47 - 0.79; P<0.01 was found. For the estimation of live weight with regression model the necessary data are as follows: hearth girth, 2nd width of rump and diagonal length of body. The determination coefficient was 0.80 (P<0.01. Height at withers, of back and at rump (h2 = 0.66, 0.67 and 0.51 showed medium heritability values. The heritability of depth of chest and height of bieler-point were 0.32 and 0.48, respectively. Quite small differences were found between the stallions in most of the body measurements. The live weight and height measurements were exceptions, as here the differences between the sires were slightly higher. As a conclusion it can be stated that the Thoroughbred population in Hungary is quite homogenous in terms of the most important body measurements.

    Full Text Available Perfluoroalkyl substances (PFASs are ubiquitous, persistent pollutants widely used in the production of common household and consumer goods. There is a limited body of literature suggesting that these chemicals may alter metabolic pathways and growth trajectories. The relationship between prenatal exposures to these chemicals and gestational weight gain (GWG has received limited attention. One objective was to analyze the associations among maternal plasma levels of three common perfluoroalkyl substances (perfluorooctanoate (PFOA, perfluorooctanesulfonate (PFOS, perfluorohexanesulfanoate (PFHxS and GWG. Additionally, we explored whether GWG was associated with cord blood PFAS levels. This study utilized data collected in the Maternal-Infant Research on Environmental Chemicals (MIREC Study, a trans-Canada cohort study of 2001 pregnant women. Our analysis quantified associations between (1 maternal PFAS concentrations and GWG and (2 GWG and cord blood PFAS concentrations. Maternal PFOS concentrations were positively associated with GWG (β = 0.39 95% CI: 0.02, 0.75. Interquartile increases in GWG were significantly associated with elevated cord blood PFOA (OR = 1.33; 95% CI: 1.13 to 1.56 and PFOS (OR = 1.20; 95% CI: 1.03 to 1.40 concentrations. No statistically significant associations were observed between GWG and either measure of PFHxS. These findings warrant elucidation of the potential underlying mechanisms.

    A better understanding of women's perceptions of weight gain and related behaviors during pregnancy is necessary to inform behavioral interventions. We used the Theory of Planned Behavior (TPB) to examine pregnant women's perceptions and intentions toward weight gain, physical activity (PA), and nutrition using a mixed methods study design. Women between 20 and 30 weeks gestation (n = 189) were recruited to complete an Internet-based survey. Salient beliefs toward weight gain, PA, and nutrition were captured through open-ended responses and content analyzed into themes. TPB constructs (attitude, subjective norm, perceived behavioral control, intentions) were examined using Pearson correlations and hierarchical linear regression models. Salient beliefs were consistent with the existing literature in non-pregnant populations, with the addition of many pregnancy-specific beliefs. TPB constructs accounted for 23-39 % of the variance in weight gain, PA, and nutrition intentions, and made varying contributions across outcomes. The TPB is a useful framework for examining women's weight-related intentions during pregnancy. Study implications for intervention development are discussed.

    Full Text Available Abstract Background The use of atypical antipsychotics in schizophrenic patients has been associated with a risk of weight gain. Similarly, recovery from depression is often followed by improved appetite, greater food intake and potential increase in weight. Case presentation A Caucasian 33-year-old schizophrenic female patient was being treated with 6 mg/day of risperidone and 15 mg/day of clorazepate. She developed depressive symptomatology and 40 mg/day of fluoxetine was gradually added to her treatment regimen for about 9 months. After the remission of depression, and the discontinuation of fluoxetine, she experienced an increase in appetite and subsequently excessive weight gain of 52 kg. Re-administration of fluoxetine did not reverse the situation. The patient developed diabetes mellitus, which was successfully controlled with metformin 1700 mg/day. The addition at first of orlistat 360 mg/day and later of topiramate 200 mg/day has helped her to lose a significant part of the weight gained (30 kg. Conclusion The case suggests a probable association between the remission of depressive symptomatology and weight gain in a schizophrenic patient.

    The objective of this study was to investigate whether pregnancy, delivery, and neonatal outcome among obese pregnant women who took part in an intervention study for weight restriction differed from a group of obese pregnant women attending regular antenatal care. The intervention group consisted of 155 obese pregnant women and 193 obese pregnant women who formed a control group. We found that a weight gain restriction of less than 7 kg during pregnancy is safe for both the mother and the neonate.

  2. Association between Maternal Fish Consumption and Gestational Weight Gain: Influence of Molecular Genetic Predisposition to Obesity.

    Directory of Open Access Journals (Sweden)

    Sofus C Larsen

    Full Text Available Studies suggest that fish consumption can restrict weight gain. However, little is known about how fish consumption affects gestational weight gain (GWG, and whether this relationship depends on genetic makeup.To examine the association between fish consumption and GWG, and whether this relationship is dependent on molecular genetic predisposition to obesity.A nested case-cohort study based on the Danish National Birth Cohort (DNBC sampling the most obese women (n = 990 and a random sample of the remaining participants (n = 1,128. Replication of statistically significant findings was attempted in the Avon Longitudinal Study of Parents and Children (ALSPAC (n = 4,841. We included 32 body mass index (BMI associated single nucleotide polymorphisms (SNPs and 5 SNPs found associated with GWG. BMI associated SNPs were combined in a genetic risk score (GRS. Associations between consumption of fish, GRS or individual variants and GWG were analysed, and interactions between fish and the GRS or individual variants were examined.In the DNBC, each portion/week (150 g of fatty fish was associated with a higher GWG of 0.58 kg (95% CI: 0.16, 0.99, P<0.01. For total fish and lean fish, similar patterns were observed, but these associations were not statistically significant. We found no association between GRS and GWG, and no interactions between GRS and dietary fish on GWG. However, we found an interaction between the PPARG Pro12Ala variant and dietary fish. Each additional Pro12Ala G-allele was associated with a GWG of -0.83 kg (95% CI: -1.29, -0.37, P<0.01 per portion/week of dietary fish, with the same pattern for both lean and fatty fish. In ALSPAC, we were unable to replicate these findings.We found no consistent evidence of association between fish consumption and GWG, and our results indicate that the association between dietary fish and GWG has little or no dependency on GRS or individual SNPs.

    Full Text Available Abstract Background Rapid weight gain in infancy is an important predictor of obesity in later childhood. Our aim was to determine which modifiable variables are associated with rapid weight gain in early life. Methods Subjects were healthy infants enrolled in NOURISH, a randomised, controlled trial evaluating an intervention to promote positive early feeding practices. This analysis used the birth and baseline data for NOURISH. Birthweight was collected from hospital records and infants were also weighed at baseline assessment when they were aged 4-7 months and before randomisation. Infant feeding practices and demographic variables were collected from the mother using a self administered questionnaire. Rapid weight gain was defined as an increase in weight-for-age Z-score (using WHO standards above 0.67 SD from birth to baseline assessment, which is interpreted clinically as crossing centile lines on a growth chart. Variables associated with rapid weight gain were evaluated using a multivariable logistic regression model. Results Complete data were available for 612 infants (88% of the total sample recruited with a mean (SD age of 4.3 (1.0 months at baseline assessment. After adjusting for mother's age, smoking in pregnancy, BMI, and education and infant birthweight, age, gender and introduction of solid foods, the only two modifiable factors associated with rapid weight gain to attain statistical significance were formula feeding [OR = 1.72 (95%CI 1.01-2.94, P = 0.047] and feeding on schedule [OR = 2.29 (95%CI 1.14-4.61, P = 0.020]. Male gender and lower birthweight were non-modifiable factors associated with rapid weight gain. Conclusions This analysis supports the contention that there is an association between formula feeding, feeding to schedule and weight gain in the first months of life. Mechanisms may include the actual content of formula milk (e.g. higher protein intake or differences in feeding styles, such as feeding to schedule

  4. Explaining rigid dieting in normal-weight women: the key role of body image inflexibility.

    Science.gov (United States)

    Ferreira, Cláudia; Trindade, Inês A; Martinho, Ana

    2016-03-01

    Restrictive dieting is an increasing behavior presented by women in modern societies, independently of their weight. There are several known factors that motivate diet, namely a sense of dissatisfaction with one's body and unfavorable social comparisons based on physical appearance. However, dieting seems to have a paradoxical effect and has been considered a risk factor for weight gain and obesity in women and for maladaptive eating. Nevertheless, the study of the emotional regulation processes that explain the adoption of inflexible and rigid eating behaviors still remains little explored. In this line, the present study aims to explore why normal-weight women engage in highly rigid and inflexible diets. We hypothesize that body and weight dissatisfaction and unfavorable social comparisons based on physical appearance explain the adoption of inflexible eating rules, through the mechanisms of body image inflexibility. The current study comprised 508 normal-weight female college students. Path analyses were conducted to explore the study's hypotheses. Results revealed that the model explained 43 % of inflexible eating and revealed excellent fit indices. Furthermore, the unwillingness to experience unwanted events related to body image (body image inflexibility) mediated the impact of body dissatisfaction and unfavorable social comparisons on the adoption of inflexible eating rules. This study highlights the relevance of body image inflexibility to explain rigid eating attitudes, and it seems to be an important avenue for the development of interventions focusing on the promotion of adaptive attitudes towards body image and eating in young women.

    Leonurus sibiricus, also called motherwort, is a well-known functional food and medicinal herb. It has been known to possess beneficial properties for women's health, especially for aged women. Estrogen deficiency in the menopause could induce lipid metabolic abnormalities in body fat, resulting in obesity. In this study, the inhibitory effects of L. sibiricus on obesity after the menopause were investigated. Female C57BL/6 mice were ovariectomized and fed high-fat diet (HFD) for 12 weeks. Following an induction period, aqueous extracts of L. sibiricus (LS) were orally administrated for 6 weeks. The body, uterine, and visceral fat weights were measured immediately after the animals were killed. Histological analysis was performed to monitor fat and liver. Serum levels of glucose, triglyceride, total cholesterol, and LDL-cholesterol were evaluated. In addition, the expression of lipases was analyzed. Total body weight was significantly decreased by LS treatment. Histological changes in adipocyte size were shown along with a decrease of visceral fat weight in the LS-treated group. In addition, the fat infiltration of liver was reduced by LS administration. LS-treated mice experienced decreases of serum triglyceride, total cholesterol, and LDL-cholesterol levels. The expression of HSL and ATGL was significantly increased by LS treatment. These results suggest that LS could regulate the lipid metabolism via an increase of lipases expression in ovariectomized and HFD-fed mice. LS might be a novel candidate for a functional food to inhibit weight gain after the menopause.

    2016-01-01

    The regulation of food intake and energy expenditure usually limits important loss or gain of body weight. Hormones (leptin, ghrelin, insulin) and nutrients (glucose, triglycerides) are among the main regulators of food intake. Leptin is also involved in leptin resistance, often associated with obesity and characterized by a reduced efficacy to regulate food intake. Mathematical models describing the dynamics of body weight have been used to assist clinical weight loss interventions or to stu...

    We examined the association of body mass index (BMI), body weight perception, and weight control behaviors with problematic Internet use in a nationwide sample of Korean adolescents. Cross-sectional data from the 2010 Korean Youth Risk Behavior Web-based Survey collected from 37,041 boys and 33,655 girls in middle- and high- schools (grades 7-12) were analyzed. Participants were classified into groups based on BMI (underweight, normal weight, overweight, and obese), body weight perception (underweight, normal weight, and overweight), and weight control behavior (no weight control behavior, appropriate weight control behavior, inappropriate weight control behavior). The risk of problematic Internet use was assessed with the Korean Internet Addiction Proneness Scale for Youth-Short Form. Both boys and girls with inappropriate weight control behavior were more likely to have problematic Internet use. Underweight, overweight, and obese boys and girls were more likely to have problematic Internet use. For both boys and girls, subjective perception of underweight and overweight were positively associated with problematic Internet use. Given the negative effect of inappropriate weight control behavior, special attention needs to be given to adolescents' inappropriate weight control behavior, and an educational intervention for adolescents to control their weight in healthy ways is needed.

    1983-12-01

    The relationships between the shelf level at which mice were housed and body weight and food consumption/wastage were examined by analyzing data obtained from the first 9 months of a carcinogenic dose-response study carried out in 24,192 female BALB/c mice using 2-acetylaminofluorene (2-AAF) as the carcinogen. Each cage, containing four mice, was maintained on a rack at a given shelf level throughout the course of the experiment to allow analysis of data by shelf level. The amount of food removed from each feeder and the body weight of each mouse was measured weekly. Average body weight gain during the first 12 weeks was lowest on the top shelf, highest on the next two shelves, and progressively lower as the shelf approached the lowest level on the rack. Body weights attained by week 36 of the experiment generally reflected this same pattern. Weekly food consumption/wastage, as measured by disappearance of food from the feeder, generally showed the converse shelf-level pattern as that shown by body weight gain. Removal of food from feeders was greatest on the top shelf, lowest on the next shelf, and progressively increased with each succeedingly lower shelf. Although it is not clear whether the food removal pattern was related more to food consumption or food wastage, the observation was reproducible.

    2010-11-01

    An inverse relationship between brain serotonin and food intake and body weight has been known for more than 30 years. Specifically, augmentation of brain serotonin inhibits food intake, while depletion of brain serotonin promotes hyperphagia and weight gain. Through the decades, serotonin receptors have been identified and their function in the serotonergic regulation of food intake clarified. Recent refined genetic studies now indicate that a primary mechanism through which serotonin influences appetite and body weight is via serotonin 2C receptor (5-HT(2C)R) and serotonin 1B receptor (5-HT(1B)R) influencing the activity of endogenous melanocortin receptor agonists and antagonists at the melanocortin 4 receptor (MC4R). However, other mechanisms are also possible and the challenge of future research is to delineate them in the complete elucidation of the complex neurocircuitry underlying the serotonergic control of appetite and body weight.

    We investigated the relationships between L/S promoter (SERTPR) and l/s intron2 (SERTin2) genetic variants of serotonin transporter (SERT) polymorphisms with olanzapine-induced weight gain and treatment response in 94 female schizophrenic patients treated with olanzapine for up to 3 months. Body mass index (BMI) was calculated for each patient prior to olanzapine administration and 3 months afterwards. To assess and evaluate improvement of clinical psychotic symptoms and therapeutic response to the antipsychotic, all patients were rated using the Positive and Negative Syndrome ScaLe (PANSS). Overall, the presence of S SERTPR allelic variant and SS genotype was associated with significantly higher weight gain in subjects who were non-obese at the time of admission. The presence of L SERTPR variant was associated with significantly better treatment response measured with total PANSS and general PANSS subscale, while the presence of l SERTin2 variant determined better treatment response only in several items. No evidence of linkage disequilibrium between the two loci was found in the sample. These findings identify genetic factors associated with oLanzapine-induced weight gain and treatment response in femaLe schizophrenic patients.

  13. Body characteristics, [corrected] dietary protein and body weight regulation. Reconciling conflicting results from intervention and observational studies?

    Directory of Open Access Journals (Sweden)

    Mikkel Z Ankarfeldt

    Full Text Available BACKGROUND/OBJECTIVES: Physiological evidence indicates that high-protein diets reduce caloric intake and increase thermogenic response, which may prevent weight gain and regain after weight loss. Clinical trials have shown such effects, whereas observational cohort studies suggest an association between greater protein intake and weight gain. In both types of studies the results are based on average weight changes, and show considerable diversity in both directions. This study investigates whether the discrepancy in the evidence could be due to recruitment of overweight and obese individuals into clinical trials. SUBJECTS/METHODS: Data were available from the European Diet, Obesity and Genes (DiOGenes post-weight-loss weight-maintenance trial and the Danish Diet, Cancer and Health (DCH cohort. Participants of the DCH cohort were matched with participants from the DiOGenes trial on gender, diet, and body characteristics. Different subsets of the DCH-participants, comparable with the trial participants, were analyzed for weight maintenance according to the randomization status (high or low protein of the matched trial participants. RESULTS: Trial participants were generally heavier, had larger waist circumference and larger fat mass than the participants in the entire DCH cohort. A better weight maintenance in the high-protein group compared to the low protein group was observed in the subgroups of the DCH cohort matching body characteristics of the trial participants. CONCLUSION: This modified observational study, minimized the differences between the RCT and observational data with regard to dietary intake, participant characteristics and statistical analysis. Compared with low protein diet the high protein diet was associated with better weight maintenance when individuals with greater body mass index and waist circumference were analyzed. Selecting subsets of large-scale observational cohort studies with similar characteristics as

    Full Text Available Background: Despite the fact that effect of massage with or without oil on the baby′s weight gain is not clear, but recent studies have shown that massage with essential oils make lipid absorption through the skin. The aim of this study was to evaluate the effect of olive oil massage on weight gain in preterm infants. Materials and Methods: This study was a single-blind, randomized controlled clinical trial. In this study, infants who met inclusion criteria for the study were divided into two groups by using random numbers table. Newborns in intervention group were under massage for 10 days and 3 times for 15 min daily; the mother of these newborns had been trained already using olive oil. Moreover, the infants of the control group were under massaging without oil same as the above-mentioned method. Researchers weighed babies daily during 10 days and recorded it at the checklist. Data from the study were reviewed and analyzed by descriptive statistics and repeated measure test using the statistical software SPSS/13. Results: This study showed that the neonatal weight gain in the infants with the oil massage was 21 g daily in average, whereas the increase in infant massage without oil was 7 g. This difference was statistically significant (P < 0.001. Conclusion: Considering the positive effect of infant massage on weight gain in premature infants with olive oil, it is recommended that nurses use oil in infant massage in the neonatal units.

    to extrapolate the influence of replacing sugary drinks with alternative beverages (water, milk and diet drinks) on Δweight or ΔBMI z-score. Sugary drink intake at baseline and substitution of sugary drinks with milk were associated with both Δweight and ΔBMI z-score. Every 100 g/d increase in sugary drink...... intake was associated with 0·10 kg and 0·06 unit increases in body weight (P=0·048) and BMI z-score (P=0·04), respectively. Substitution of 100 g/d sugary drinks with 100 g/d milk was inversely associated with Δweight (β=-0·16 kg; P=0·045) and ΔBMI z-score (β=-0·07 units; P=0·04). The results...... of this study suggest that sugary drink consumption was associated with body weight gain among young children with high predisposition for future overweight. In line with the current recommendations, sugary drinks, whether high in added or natural sugar, should be discouraged to help prevent childhood obesity...

    Within the past 5 years there has been an increase of premature infants surviving in the neonatal intensive care unit as well as an increasing cost for each day the infant is kept there. It is important for the premature infant to acquire the feeding skills necessary for weight gain, which lead to discharge from the hospital, and recent advancements have indicated the effectiveness in using contingent music to teach sucking skills to premature infants. The purpose of the first analysis in this study was to determine the effects of Pacifier Activated Lullaby (PAL) trials on weight gain of premature infants. During a 2-year time period, 62 infants from a sample of 188 met criteria for analysis. A one-way analysis of variance showed no significance in daily weight gain for the number of PAL trials completed. The mean weight gains for infants with 1 PAL trial = 13.85 grams, 2 trials = 26.67, 3 trials = 29.64, and 4 or more = 22.89. The Pearson product-moment correlation between the mean percent of music earned via nonnutritive sucking (NNS) and mean weight gain of all trials approached significance (p = .077, r = 0.18). In a second analysis, weight gained prior to use of PAL, during use of PAL, and post use of PAL was analyzed. Results indicated no significant difference between weight gain 1 day prior to use of PAL, the day of PAL trial, and 1 day post use of PAL. Mean weight gain for those infants who participated in 1 PAL trial was 8.49 grams for 1 day prior to use of PAL, 18.73 the day of PAL trial, and 24.81 for 1 day post use of PAL. Mean weight gain for 3 days prior to using the PAL was 10.78, 11.30 on the day of PAL trial, and 24.78 grams for 3 days post PAL use. The analyses show definite trends of greater weight gain with PAL use; however, individual variability within groups was greater than group differences leading to no significance in statistical analysis. In the third analysis the effect of proximity between premature infants' feeding schedule and PAL

    Background The social valorisation of overweight in African populations could promote high-risk eating behaviours and therefore become a risk factor of obesity. However, existing scales to assess body image are usually not accurate enough to allow comparative studies of body weight perception in different African populations. This study aimed to develop and validate the Body Size Scale (BSS) to estimate African body weight perception. Methods Anthropometric measures of 80 Cameroonians and 81 ...

    We investigated main and interactive effects of maternal pre-pregnancy obesity and gestational weight gain on circadian cortisol from the second to third trimester. A diverse sample of 215 pregnant women was enrolled. Maternal height and most recent pre-pregnancy weight were collected at study initiation (22% obese). Weight and circadian salivary cortisol samples were measured during second (24±4) and third (35±1 weeks) trimesters. During the third trimester, women who were obese prior to conception showed elevated evening cortisol versus normal weight women. This pattern was moderated by weight gain in excess of Institute of Medicine guidelines, such that women who were obese prior to conception and gained greater than 7.94kg by the 35±1 week visit displayed greatest elevations in evening cortisol. Given links between excessive prenatal glucocorticoid exposure and both poor maternal and offspring health outcomes, elevated maternal cortisol may be one mechanism underlying links between maternal obesity and adverse perinatal outcomes.

    High-fat diets rapidly cause weight gain and glucose intolerance. We sought to determine whether these changes could be mitigated with prior exercise training. Male C57BL/6J mice were exercise-trained by treadmill running (1 h/day, 5 days/wk) for 4 wk. Twenty-four hours after the final bout of exercise, mice were provided with a high-fat diet (HFD; 60% kcal from lard) for 4 days, with no further exercise. In mice fed the HFD prior to exercise training, the results were blunted weight gain, reduced fat mass, and a slight attenuation in glucose intolerance that was mirrored by greater insulin-induced Akt phosphorylation in skeletal muscle compared with sedentary mice fed the HFD. When ad libitum-fed sedentary mice were compared with sedentary high-fat fed mice that were calorie restricted (-30%) to match the weight gain of the previously trained high-fat fed mice, the same attenuated impairments in glucose tolerance were found. Blunted weight gain was associated with a greater capacity to increase energy expenditure in trained compared with sedentary mice when challenged with a HFD. Although mitochondrial enzymes in white adipose tissue and UCP-1 protein content in brown adipose tissue were increased in previously exercised compared with sedentary mice fed a HFD, ex vivo mitochondrial respiration was not increased in either tissue. Our data suggest that prior exercise training attenuates high-fat diet-induced weight gain and glucose intolerance and is associated with a greater ability to increase energy expenditure in response to a high-fat diet.

    Cancer cachexia is a well-recognized syndrome in human patients that is characterized by progressive involuntary weight loss. The prevalence of this syndrome in veterinary cancer patients is unknown. This study's objective was to investigate the occurrence of weight loss and cachexia, as characterized by body condition scoring, in dogs presented to a veterinary oncology service. Information collected on 100 dogs included signalment, diagnosis, weight at time of diagnosis, and, when available, weight from a time approximately 12 months before diagnosis. Body condition was assessed by using a 9-point system based on body silhouette and palpation of adipose tissue (4-5 = optimal, 1 = extreme cachexia, 9 = extreme obesity). Muscle wasting was scored based on palpation of skeletal muscle (3 = no wasting, 2 = mild, 1 = moderate, 0 = severe). Only 4% of the dogs exhibited cachexia as defined by a body condition score or = 7). Fifteen percent had evidence of clinically relevant muscle wasting (dogs. At the time of diagnosis, 31% had maintained or gained weight, 31% had lost up to 5%, 14% had lost between 5 and 10%, and 23% had lost >10% of body weight. Overall, the percentage of dogs with signs indicating a decline in nutritional status was less than what has been reported for human cancer patients. Future studies should investigate the extent to which weight loss occurs in canine patients on an appropriate plane of nutrition as well as to establish whether an association exists between poor nutritional status and outcome in canine cancer patients.

    Across species obesity is associated with several disorders but in companion animals little information is available on the impact of chronic obesity on immune competence. The aim of the present study was to investigate whether weight gain and stable obese bodyweight affects the immune cell response. Obesity was induced in eight adult healthy beagle dogs (weight gain group; WGG) by a weight gain period (WGP) of 47 weeks, which was immediately followed by a period (stable period: SP) of stable obesity of 26 weeks. Eight adult healthy beagle dogs were included as a control group (CG) and remained at their ideal bodyweight throughout the entire study. Body composition was measured at five intervening time-points. Concentration of serum leptin and inflammatory cytokines, functionality of lymphocytes and phagocytic activity of neutrophils and monocytes were evaluated at ten intervening time-points. Serum leptin concentration was rising during the WGP in the WGG but went to lower concentrations during the SP. At the end of long-term weight gain, a decreased mitogen-induced proliferation of T-lymphocytes was noted but this alteration seemed to be transient after stabilization of bodyweight. This finding may imply an altered immune response for dogs with different energy balances. However, no systemic low grade inflammation or alteration in other immune cell functions was observed. Consequently it is suggested that the change in energy balance during the onset of obesity (becoming obese versus being obese), evokes an additional obesity-related disorder in dogs, i.e. impaired T-lymphocyte immune function.

    Behavioural therapy and bariatric surgery often produce rapid, massive body weight loss that may impact a patient's ability to gauge his/her new body shape. Although the patient is aware of the weight loss, he/she continues to feel obese, as if there was a conflict between the previous body schema and the new one. Here, we report the case of a 40-year-old woman who developed major body distortions after massive weight loss. Psychometric and behavioural assessments revealed strong disturbances in several tasks involving body representation. In particular, we observed abnormal behaviour in a body-scaled action task. Our findings suggest that the rapidity of our patient's weight loss prevented her central nervous system from correctly updating the body schema.

    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.

    Full Text Available Fatty acids (FAs are fundamental for a foetus’s growth, serving as an energy source, structural constituents of cellular membranes and precursors of bioactive molecules, as well as being essential for cell signalling. Long-chain polyunsaturated FAs (LC-PUFAs are pivotal in brain and visual development. It is of interest to investigate whether and how specific pregnancy conditions, which alter fatty acid metabolism (excessive pre-pregnancy body mass index (BMI or gestational weight gain (GWG, affect lipid supply to the foetus. For this purpose, we evaluated the erythrocyte FAs of mothers and offspring (cord-blood at birth, in relation to pre-pregnancy BMI and GWG. A total of 435 mothers and their offspring (237 males, 51% were included in the study. Distribution of linoleic acid (LA and α-linolenic acid (ALA, and their metabolites, arachidonic acid, dihomogamma linoleic (DGLA and ecosapentanoic acid, was significantly different in maternal and foetal erythrocytes. Pre-pregnancy BMI was significantly associated with maternal percentage of MUFAs (Coeff: −0.112; p = 0.021, LA (Coeff: −0.033; p = 0.044 and DHA (Coeff. = 0.055; p = 0.0016; inadequate GWG with DPA (Coeff: 0.637; p = 0.001; excessive GWG with docosaexahenoic acid (DHA (Coeff. = −0.714; p = 0.004. Moreover, pre-pregnancy BMI was associated with foetus percentage of PUFAs (Coeff: −0.172; p = 0.009, omega 6 (Coeff: −0.098; p = 0.015 and DHA (Coeff: −0.0285; p = 0.036, even after adjusting for maternal lipids. Our findings show that maternal GWG affects maternal but not foetal lipid profile, differently from pre-pregnancy BMI, which influences both.

    Metabolic and behavioral changes that occur during pregnancy have well-known effects on maternal and fetal health during the immediate pregnancy and now are thought to be a catalyst for future health throughout later life. Recommendations for appropriate gestational weight gain (GWG) and lifestyle modifications during pregnancy have changed throughout history as more is known about this crucial time. Herein we discuss the current GWG recommendations and the impact of pregnancy and excess GWG gain on the current and future health of women and children including risk of obesity, gestational diabetes, type 2 diabetes, cardiovascular disease, and metabolic syndrome.

    The current study was aimed to evaluate gestational weight gain and its socio-demographic determinants among pregnant women in north-west of Iran. In the current cross-sectional study, four hundred eighty one pregnant women aged 26.12 ± 7.45 years were enrolled. Data on pre-pregnancy weight, height, age, educational attainment, parity, household size, hemoglobin status and total pregnancy weight gain were extracted from routine health center records. The pregnant women were categorized based on their pre-pregnancy body mass index (BMI) as underweight, normal weight and overweight or obese according to the 2009 Institute of Medicine (IOM) recommendations. Participants were also classified according to their educational level into three 'some school', 'high school' and 'college' groups. Gestational weight gain in 27.6% of pregnant women was in normal IOM recommended range; while, weight gain in 49% and 23.2% of pregnant women was below and above recommended range respectively. Women with high educational attainment (≥12 years) have significantly higher weight gain compared with low-educated women (nutritional status and health care programs in current health care services in Iran.

    2014-07-01

    Adults consume millions of kilocalories over the course of a few years, but the typical weight gain amounts to only a few thousand kilocalories of stored energy. Furthermore, food intake is highly variable from day to day and yet body weight is remarkably stable. These facts have been used as evidence to support the hypothesis that human body weight is regulated by active control of food intake operating on both short and long time scales. Here, we demonstrate that active control of human food intake on short time scales is not required for body weight stability and that the current evidence for long term control of food intake is equivocal. To provide more data on this issue, we emphasize the urgent need for developing new methods for accurately measuring energy intake changes over long time scales. We propose that repeated body weight measurements can be used along with mathematical modeling to calculate long-term changes in energy intake and thereby quantify adherence to a diet intervention and provide dynamic feedback to individuals that seek to control their body weight.

    finished in feedlot randomly allocated in four groups according to urea levels (0.0; 0.4; 0.8 and 1.2% of total dry matter. Animals were slaughtered with 32kg of live weight. There was no difference among urea levels for the following parameters: daily weight gain, live weight at slaughter, hot and chilled carcass weights, percentage of weight losses during chilling, commercial and biological carcass dressing out, non-carcass components weights, body condition and conformation, and fat deposition. However, for the skin weight (kg the 0.0% level was lower than the 0.8% level. There were not observed differences among treatments for the following variables: muscle pH at three moments, morphometric and carcass cut proportions. The leg length of the lambs fed diet with 0.8% urea was lower than that of 0.0% level. For leg compacity, 0.8% was smaller than the leg length of those fed with 0.o% urea. It was concluded that growing levels of urea utilization is viable and did not affect the variables that were analyzed in this work.

    Full Text Available Obesity is reaching epidemic proportions in both developed and developing countries. Even modest weight gain increases the risk for chronic illness, yet evidence-based interventions to prevent weight gain are rare. This trial will determine if a simple low-intensity intervention can prevent weight gain in women compared to general health information.We conducted a 1-yr pragmatic, cluster randomised controlled trial in 41 Australian towns (clusters randomised using a computer-generated randomisation list for intervention (n = 21 or control (n = 20. Women aged 18 to 50 yr were recruited from the general population to receive a 1-yr self-management lifestyle intervention (HeLP-her consisting of one group session, monthly SMS text messages, one phone coaching session, and a program manual, or to a control group receiving one general women's health education session. From October 2012 to April 2014 we studied 649 women, mean age 39.6 yr (+/- SD 6.7 and BMI of 28.8 kg/m(2 (+/- SD 6.9 with the primary outcome weight change between groups at 1 yr. The mean change in the control was +0.44 kg (95% CI -0.09 to 0.97 and in the intervention group -0.48 kg (95% CI -0.99 to 0.03 with an unadjusted between group difference of -0.92 kg (95% CI -1.67 to -0.16 or -0.87 kg (95% CI -1.62 to -0.13 adjusted for baseline values and clustering. Secondary outcomes included improved diet quality and greater self-management behaviours. The intervention appeared to be equally efficacious across all age, BMI, income, and education subgroups. Loss to follow-up included 23.8% in the intervention group and 21.8% in the control group and was within the anticipated range. Limitations include lack of sensitive tools to measure the small changes to energy intake and physical activity. Those who gained weight may have been less inclined to return for 1 yr weight measures.A low intensity lifestyle program can prevent the persistent weight gain observed in women.

    Pancreatic polypeptide (PP) is released from the pancreas in response to a meal. In humans, low-circulating PP levels have been observed in obesity, and administration of pharmacological doses of PP has been shown to decrease food intake. The aim of the present study was to investigate whether low...... circulating PP is associated with weight gain in Pima Indians.

    Most patients with type 2 diabetes present with comorbid overweight or obesity. Reaching and maintaining acceptable glycemic control is more difficult in overweight and obese patients, and these conditions are associated with increased risk for cardiovascular and other diseases. Glycemic management for these patients is complicated by the fact that insulin and many of the oral medications available to treat type 2 diabetes produce additional weight gain. However, an increasing number of therapeutic options are available that are weight neutral or lead to weight loss in addition to their glycemic benefits. This article evaluates the evidence from clinical trials regarding the relative glycemic benefits, measured in terms of glycated hemoglobin change, versus the impact on body weight of each medication currently approved for type 2 diabetes. In general, the sulfonylureas, thiazolidinediones, and D-phenylalanine derivatives have been shown to promote weight gain. The dipeptidyl peptidase-4 inhibitors are weight neutral, while the biguanides, incretin mimetics, and amylin mimetics promote weight loss. Trials examining the glycemic benefits of the weight loss agents orlistat and sibutramine are also examined. Awareness of this evidence base can be used to inform medication selection in support of weight management goals for patients with type 2 diabetes.

    Bradley, J A; Niilo, L

    1985-04-01

    Concentrations of immunoglobulins and total proteins in second-day post-partum serum samples of 62 beef calves from multiparous dams were measured by zinc sulphate turbidity, electrophoresis, radial immunodiffusion and refractometry. These results, together with health records and weight gains, were used to evaluate the practice of routinely force-feeding 1 L of stored colostrum to suckled beef calves immediately after birth. There was no apparent benefit from such force-feeding. It did not result in greater 48-hour serum immunoglobulin levels, nor did it improve weight gains at 42 days. None of the calves required treatment for neonatal disease, but one force-fed calf died from inhalation of regurgitated colostrum.

  7. Weight Gain, Metabolic Syndrome, and Breast Cancer Recurrence: Are Dietary Recommendations Supported by the Data?

    2012-01-01

    Full Text Available Metabolic syndrome, which can include weight gain and central obesity, elevated serum insulin and glucose, and insulin resistance, has been strongly associated with breast cancer recurrence and worse outcomes after treatment. Epidemiologic and prospective data do not show conclusive evidence as to which dietary factors may be responsible for these results. Current strategies employ low-fat diets which emphasize supplementing calories with increased intake of fruit, grain, and vegetable carbohydrate sources. Although results thus far have been inconclusive, recent randomized trials employing markedly different dietary strategies in noncancer patients may hold the key to reducing multiple risk factors in metabolic syndrome simultaneously which may prove to increase the long-term outcome of breast cancer patients and decrease recurrences. Since weight gain after breast cancer treatment confers a poor prognosis and may increase recurrence rates, large-scale randomized trials are needed to evaluate appropriate dietary interventions for our breast cancer patients.

    Objective To estimate the percentage of infants with large birth size attributable to excess gestational weight gain (GWG), independent of prepregnancy body mass index, among mothers with preexisting diabetes mellitus (PDM). Study design We analyzed 2004–2008 Florida linked birth certificate and maternal hospital discharge data of live, term (37–41 weeks) singleton deliveries (N = 641,857). We calculated prevalence of large-for-gestational age (LGA) (birth weight-for-gestational age ≥ 90th percentile) and macrosomia (birth weight > 4500 g) by GWG categories (inadequate, appropriate, or excess). We used multivariable logistic regression to estimate the relative risk (RR) of large birth size associated with excess compared to appropriate GWG among mothers with PDM. We then estimated the population attributable fraction (PAF) of large birth size due to excess GWG among mothers with PDM (n = 4427). Results Regardless of diabetes status, half of mothers (51.2%) gained weight in excess of recommendations. Large birth size was higher in infants of mothers with PDM than in infants of mothers without diabetes (28.8% versus 9.4% for LGA, 5.8% versus 0.9% for macrosomia). Among women with PDM, the adjusted RR of having an LGA infant was 1.7 (95% CI 1.5, 1.9) for women with excess GWG compared to those with appropriate gain; the PAF was 27.7% (95% CI 22.0, 33.3). For macrosomia, the adjusted RR associated with excess GWG was 2.1 (95% CI 1.5, 2.9) and the PAF was 38.6% (95% CI 24.9, 52.4). Conclusion Preventing excess GWG may avert over one-third of macrosomic term infants of mothers with PDM. Effective strategies to prevent excess GWG are needed. PMID:27539071

  10. Physical Activity Plays an Important Role in Body Weight Regulation

    Directory of Open Access Journals (Sweden)

    Jean-Philippe Chaput

    2011-01-01

    Full Text Available Emerging literature highlights the need to incorporate physical activity into every strategy intended to prevent weight gain as well as to maintain weight loss over time. Furthermore, physical activity should be part of any plan to lose weight. The stimulus of exercise provides valuable metabolic adaptations that improve energy and macronutrient balance regulation. A tight coupling between energy intake and energy expenditure has been documented at high levels of physical exercise, suggesting that exercise may improve appetite control. The regular practice of physical activity has also been reported to reduce the risk of stress-induced weight gain. A more personalized approach is recommended when planning exercise programs in a clinical weight loss setting in order to limit the compensatory changes associated to exercise-induced weight loss. With modern environment promoting overeating and sedentary behavior, there is an urgent need for a concerted action including legislative measures to promote healthy active living in order to curb the current epidemic of chronic diseases.

    Fish consumption is the major dietary source of EPA and DHA, which according to rodent experiments may reduce body fat mass and prevent obesity. Only a few human studies have investigated the association between fish consumption and body-weight gain. We investigated the association between fish consumption and subsequent change in body weight. Women and men (n 344,757) participating in the European Prospective Investigation into Cancer and Nutrition were followed for a median of 5.0 years. Linear and logistic regression were used to investigate the associations between fish consumption and subsequent change in body weight. Among women, the annual weight change was 5.70 (95 % CI 4.35, 7.06), 2.23 (95 % CI 0.16, 4.31) and 11.12 (95 % CI 8.17, 14.08) g/10 g higher total, lean and fatty fish consumption per d, respectively. The OR of becoming overweight in 5 years among women who were normal weight at enrolment was 1.02 (95 % CI 1.01, 1.02), 1.01 (95 % CI 1.00, 1.02) and 1.02 (95 % CI 1.01, 1.04) g/10 g higher total, lean and fatty consumption per d, respectively. Among men, fish consumption was not statistically significantly associated with weight change. Adjustment for potential over- or underestimation of fish consumption did not systematically change the observed associations, but the 95 % CI became wider. The results in subgroups from analyses stratified by age or BMI at enrolment were not systematically different. In conclusion, the present study suggests that fish consumption has no appreciable association with body-weight gain.

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

    Patients with schizophrenia experience higher rates of obesity and related morbidity and mortality than the general population does. Given preclinical studies revealing the role of histamine H1 receptor in human eating behavior, and the potential of olanzapine to block with this system, we hypothesized that histamine H1 receptor agonists may be beneficial in reducing antipsychotic-associated weight gain. In the present study, 36 patients with a diagnosis of schizophrenia or schizoaffective disorder and treated with olanzapine were randomized to betahistine (48 mg/d) or matching placebo for 16 weeks. Study outcomes were change in body weight from baseline and effect on antipsychotic efficacy of olanzapine. The patients in the betahistine group had less weight gain (-1.95 kg) compared with placebo group (5.6 + 5.5 kg vs 6.9 + 5.6 kg, respectively). Positive and Negative Syndrome Scale Questionnaire showed improvement within each group and that subjects treated with betahistine enjoyed an improvement (reduction) by a mean of 35.7 points, higher when compared with placebo subjects who had a reduction of 26.6 points (P = 0.233). An almost equal amount of subjects in both groups experienced adverse effects during the course of this study (87.5% of betahistine vs 85.0% of placebo-treated subjects). Overall, there were no clinically marked differences in safety signals between both groups. A larger study addressing the weaknesses of this pilot study is warranted.

    Excess body weight is a very serious problem, especially in North America and Europe. It has been referred to as a "pandemic" since it has progressively increased over the past several decades. Moreover, excess body weight significantly increases the risk of numerous diseases and clinical disorders, including all-cause mortality, coronary and cerebrovascular diseases, various cancers, type 2 diabetes mellitus, hypertension, liver disease and asthma, as well as psychopathology, among others. Unfortunately, overweight and obesity are now common in both young children and adolescents. Although the causes of excess body weight are multi-factorial, the most important factors are excess caloric intake coupled with limited energy expenditure. Therefore, lifestyle modification can significantly reduce the risk of morbidity and mortality and thereby increase longevity and improve the quality of life.

    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...... observed. The study shows that the aim of achieving a normal body does not eclipse the importance of enacting values linked to ideas of the ‘normal consumer’. Using empirical examples, the study illuminates how consumer freedom is attained in ways that are both complementary to, and in conflict with...

    The objective was to characterize puerperal women in relation to gestational weight gain and their newborns in accordance with the nutritional state at birth. This is a descriptive, quantitative and retrospective study approved by the Ethics Committee at the institution responsible. The collection of data was from December 2012 to May 2013. The sample was composed of 24 puerperal women and their children. The participants presented an average age of 26.5 (DP=5.4) years, 79.2% white; 91.7% married; 58.3% multiparous; 75% with a level of education between secondary school and higher education; 58.3% with a low family income; 54.1% presented an altered pre-gestational nutritional state and 75% obtained an inadequate gestational weight gain. 79.2% of the newborns were classified as Adequate for Gestational Age (AIG). The newborns classified as Large for Gestational Age (GIG) were from pregnant women that had excessive weight gain or were overweight. It was concluded that health professionals should be attentive to nutritional deviations with the intention of avoiding complications for maternal/fetal health.

  19. Betahistine decreases olanzapine-induced weight gain and somnolence in humans.

    Science.gov (United States)

    Barak, Nir; Beck, Yaffa; Albeck, Joseph H

    2016-03-01

    Olanzapine's efficacy in schizophrenia is attributed to antagonism of dopamine and serotonin receptors. Olanzapine is also a potent histamine-H1 antagonist that results in weight gain and somnolence. Betahistine is a centrally acting histamine-H1 agonist, and therefore may reduce olanzapine's effect on histamine receptors in the brain. Olanzapine's high affinity for the histamine-H1 receptor warrants the use of high doses of betahistine. Forty-eight healthy women were recruited and randomized to receive either betahistine 144 mg/day or matching placebo for 4 weeks. Due to the high dose of betahistine, olanzapine was started only on the second week and titrated up to 10 mg/day, and co-administration continued for an additional 2 weeks. Only nominal differences in adverse events were noted between the treatment groups. Betahistine caused a 37% reduction in mean weight gain (1.24 kg in the betahistine arm vs. 1.93 kg in the placebo arm; p=.049) and 60% reduction in the mean increase in daytime Epworth sleepiness scores (1.82 units in the betahistine group vs. 3.57 units in the placebo group; p=.042). The present study suggests that betahistine-olanzapine co-administration, in healthy female subjects, yields an acceptable safety profile with mitigation of weight gain and somnolence. This should be further tested in a patient cohort.

  20. Leptin and inhibin B as predictors of reproductive recovery in patients with anorexia nervosa during weight gain

    Directory of Open Access Journals (Sweden)

    Ćetković Aleksandar

    2006-01-01

    Full Text Available Introduction: Anorexia nervosa represents an eating disorder that is associated with substantial psychological, social and physiological abnormalities, involving 0.5-2% of female population. Objective: The secretion patterns of inhibin B, as marker of gonadal activity, and leptin, as an indicator of energy balance and body composition, were analyzed in our cross-sectional study in order to asses the restoration of reproductive function in patients with anorexia nervosa (AN during gaining of normal weight. Method: The study included 20 patients with low weight AN (BMI 14.3±0.3 kg/mI, 22 partially recovered AN (BMI 17.4±0.1 kg/mI, and 29 gained regular weight, out of whom 16 had no restoration of menstrual cycle (BMI 19.5±0.1 kg/mI, and 13 had at least six consecutive menstrual cycles (BMI 19.3±1.0 kg/mI. Nineteen eumenorrheic females with BMI 19.8±0.4 kg/mI were the controls. Results: Significant correlation between leptin and inhibin B (ς=0.446; p=0.000, leptin and delta LH (ς=0.611; p<0.001, and inhibin B and delta LH (ς=0.574; p<0.001 was found in patients with anorexia nervosa during weight gain. Leptin (p=0.0039, inhibin B (p=0.0173, LH (p=0.0323 and delta LH (p=0.0087 were important predictors of reproductive recovery in patients with anorexia nervosa during gaining of normal weight. Among aforementioned parameters, leptin (p=0.0057 appeared to be the most important. Conclusion: Leptin is the most important predictor of reproductive recovery in patients with anorexia nervosa during weight normalization. These findings suggest that decreased leptin levels may be responsible for several neuroendocrine abnormalities seen in anorexia nervosa. Thus, interventional studies involving administration of recombinant leptin are required to fully clarify the physiologic and potentially therapeutic role of leptin in anorexia nervosa.

    The purpose of this study was to determine the relative importance of inadequate gestational weight gain as a cause of infant mortality. Birth and infant death certificate data were obtained from a random sample of 100,000 records from the National Center for Health Statistics (NCHS) 2002 Birth Cohort Linked Birth/Infant Death Data File. Descriptive and proportional hazards regression analyses were used to assess the odds of infant mortality associated with inadequate gestational weight gain compared to normal weight gain. Nearly 30% of women experienced inadequate weight gain. Infants born to women with inadequate gestational weight gain had odds of infant death that were 2.23 times the odds for infants born to women with normal weight gain. Increased odds remained after adjustment for gestational age, low birth weight, maternal age, maternal education, and maternal race. Among racial or ethnic subgroups, African American women were 1.3 times as likely as white women to have an infant die, but they were no more likely to have an infant die than white women if they had inadequate weight gain. There is a substantial and significant association between inadequate gestational weight gain and infant death that does not differ by race, ethnic group membership, or maternal age.

    The causes of the current high prevalence of overweight and obesity among children are not clearly known. Schools have been implicated in the causal chain to high child obesity prevalence. Recent studies have compared school year versus summertime changes (herein called seasonal differences) in child adiposity or related phenomena. The most common seasonal pattern in six longitudinal descriptive studies was that overweight and obese children experienced accelerated gain in weight or some BMI indicator during the summer, whereas healthy weight children gained less or not at all. Four physical activity (PA) intervention studies demonstrated that school year fitness improvements were lost during the summer. One study showed that PA declined across the summer. Another study provided conflicting results of lower total energy expenditure in the summer, but no seasonal difference in total energy expenditure after adjusting for fat-free mass. This pattern of fairly rapid seasonal differences suggests that PA is the primary factor contributing to seasonal differences in weight or BMI, but the documented seasonal pattern in PA (i.e., higher in summer) does not support this relationship. Sleep duration has also been inversely related to child adiposity. Seasonal patterns in adiposity, PA, and sleep need to be clearly established separately for overweight and healthy weight children in further longitudinal research to provide a clear focus for national policy.

    With increasingly adverse lifestyles, young women in many countries have rapid weight gain and rising obesity. In keeping with this, most pregnant women exceed recommended gestational weight gain (GWG) and then retain weight postpartum. The consequences of excess GWG include maternal risks during pregnancy, neonatal risks and maternal obesity and chronic disease longer term, presenting a significant public health and economic burden worldwide. This article discusses the adverse maternal and infant risks with excess GWG apparent from observational studies, summarizes the existing guidelines for optimal GWG and highlights the need for further research to identify optimal GWG recommendations across the different ethnicities and weight ranges.We also review the evidence for lifestyle interventions in pregnancy to prevent excess GWG and highlighting the work underway to integrate large scale meta-analyses of individual patient data from lifestyle intervention studies to inform clinical practice beyond current observational data. Finally, we address the need to implement lifestyle interventions into routine pregnancy care to improve short and long term maternal health outcomes.

    Full Text Available Dehydration secondary to gastroenteritis is one of the most common reasons for office visits and hospital admissions. The indicator most commonly used to estimate dehydration status is acute weight loss. Post-illness weight gain is considered as the gold-standard to determine the true level of dehydration and is widely used to estimate weight loss in research. To determine the value of post-illness weight gain as a gold standard for acute dehydration, we conducted a prospective cohort study in which 293 children, aged 1 month to 2 years, with acute diarrhea were followed for 7 days during a 3-year period. The main outcome measures were an accurate pre-illness weight (if available within 8 days before the diarrhea, post-illness weight, and theoretical weight (predicted from the child's individual growth chart. Post-illness weight was measured for 231 (79% and both theoretical and post-illness weights were obtained for 111 (39%. Only 62 (21% had an accurate pre-illness weight. The correlation between post-illness and theoretical weight was excellent (0.978, but bootstrapped linear regression analysis showed that post-illness weight underestimated theoretical weight by 0.48 kg (95% CI: 0.06-0.79, p<0.02. The mean difference in the fluid deficit calculated was 4.0% of body weight (95% CI: 3.2-4.7, p<0.0001. Theoretical weight overestimated accurate pre-illness weight by 0.21 kg (95% CI: 0.08-0.34, p = 0.002. Post-illness weight underestimated pre-illness weight by 0.19 kg (95% CI: 0.03-0.36, p = 0.02. The prevalence of 5% dehydration according to post-illness weight (21% was significantly lower than the prevalence estimated by either theoretical weight (60% or clinical assessment (66%, p<0.0001.These data suggest that post-illness weight is of little value as a gold standard to determine the true level of dehydration. The performance of dehydration signs or scales determined by using post-illness weight as a gold standard has to be

    elevados.The net energy content for maintenance (NEm and gain (NEg of the napiergrass, under rotational grazing, as well as the changes on protein and fat concentrations in body and in weight gain of 36 ¾ Gyr-Holstein steers, grazing the forage, during the rainy season were determined. Half of steers had grazing time restricted to four hours daily, to limit energy intake to a level close to the maintenance level, and half had free access to the pasture. Six steers were slaughtered at begining of the trial, to determine initial body composition, and six (three from each treatment, at each subsequent 35 day. Prediction equations of the changes of body composition, with increase of body weight, were fitted by regression of log10 body content of protein and fat on log10 empty body weight. By differentiation of those equations, the prediction equations of composition of weight gain were obtained. The energy concentrations were estimated from protein and fat content and respective calorie equivalents. By regression of retained energy (RE on metabolizable energy (ME intake, the efficiency of ME utilization for gain, as the regression coeficient, and the ME requirement for maintenance (level of ME intake for RE = 0 were estimated. The efficiency of utilization of ME for maintenance (Km was obtained by the ratio: Km = NEm/MEm. The NEm and NEg of napiergrass were determined, respectively, as the products of Km and Kg to ME content of the forage, and the values 1.02 and 0.59 Mcal/kg dry matter, respectively, were obtained. The protein concentrations in the body and in body weight gain remained in higher levels and the fat energy concentrations remained in lower levels than those reported, in Brazil, for zebu and crossbred steers showing higher weight gains.

    America's obesity epidemic has gathered much media attention recently. A rise in the percent of the population who are obese coincides with an increase in the widespread use of non-caloric artificial sweeteners, such as aspartame (e.g., Diet Coke) and sucralose (e.g., Pepsi One), in food products (Figure 1). Both forward and reverse causalities have been proposed. While people often choose "diet" or "light" products to lose weight, research studies suggest that artificial sweeteners may contribute to weight gain. In this mini-review, inspired by a discussion with Dr. Dana Small at Yale's Neuroscience 2010 conference in April, I first examine the development of artificial sweeteners in a historic context. I then summarize the epidemiological and experimental evidence concerning their effects on weight. Finally, I attempt to explain those effects in light of the neurobiology of food reward.

    Full Text Available Tuberculosis still remains a major public health problem even though it is treatable and curable. Weight gain measurement during anti tuberculosis (TB treatment period is an important component to assess the progress of TB patients. In this study, Latent Growth Models (LGMs were implemented in a longitudinal design to predict the change in weight of TB patients who were given three different regimens under randomized controlled clinical trial for anti-TB treatment. Linear and Quadratic LGMs were fitted using Mplus software. The age, sex and treatment response of the TB patients were used as time invariant independent variables of the growth trajectories. The quadratic trend was found to be better in explaining the changes in weight without grouping than the quadratic model for three group comparisons. A significant increase in the change of weight over time was identified while a significant quadratic effect indicated that weights were sustained over time. The growth rate was similar in both the groups. The treatment response had significant association with the growth rate of weight scores of the patients.

  12. Body weight, anorexia, and undernutrition in older people.

    Ideal body weight for maximum life expectancy increases with advancing age. Older people, however, tend to weigh less than younger adults, and old age is also associated with a tendency to lose weight. Weight loss in older people is associated with adverse outcomes, particularly if unintentional, and initial body weight is low. When older people lose weight, more of the tissue lost is lean tissue (mainly skeletal muscle) than in younger people. When excessive, the loss of lean muscle tissue results in sarcopenia, which is associated with poor health outcomes. Unintentional weight loss in older people may be a result of protein-energy malnutrition, cachexia, the physiological anorexia of aging, or a combination of these. The physiological anorexia of aging is a decrease in appetite and energy intake that occurs even in healthy people and is possibly caused by changes in the digestive tract, gastrointestinal hormone concentrations and activity, neurotransmitters, and cytokines. A greater understanding of this decrease in appetite and energy intake during aging, and the responsible mechanisms, may aid the search for ways to treat undernutrition and weight loss in older people.

    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

    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

    Full Text Available Abstract Background LeptiCore® is a proprietary combination of various ingredients which have been shown to have properties which could be beneficial to weight loss in obese and overweight human subjects. This study evaluates the effect of Lepticore® on bodyweight as well as parameters associated with obesity and metabolic syndrome. Methods The study was an 8 week randomized, double-blind, placebo-controlled design involving 92 obese (mean BMI > 30 kg/m2 participants (37 males; 55 females; ages 19-52; mean age = 30.7. The participants were randomly divided into three groups: placebo (n = 30, LeptiCore® formula A (low dose (n = 31 and LeptiCore® formula B (high dose (n = 31. Capsules containing the placebo or active formulations were administered twice daily before meals with 300 ml of water. None of the participants followed any specific diet nor took any weight-reducing medications for the duration of the study. A total of 12 anthropomorphic and serological measurements were taken at the beginning of the study and after 2, 4, 6, and 8 weeks of treatment. Results Compared to the placebo group, the two active groups showed statistically significant differences on all 12 variables by week 8. These included four anthropomorphic variables (body weight, body fat, waist and hip size and eight measures of serological levels (plasma total cholesterol, LDL, HDL, triglycerides, blood glucose, serotonin, leptin, C-reactive protein. The two active groups also showed significant intra-group differences on all 12 variables between study onset and week 8. Conclusion The LeptiCore® formulation at both the low and high dosages appears to be helpful in the management of fat gain and its related complications. The higher dosage resulted in significantly greater reductions in body weight and triglyceride, blood glucose, and C-reactive protein levels, as well as increased serotonin levels.

    2013-02-01

    Full Text Available Abstract Background Maternal feeding practices have been proposed to play an important role in early child weight gain and obesogenic eating behaviors. However, to date longitudinal investigations in young children exploring these relationships have been lacking. The aim of the present study was to explore prospective relationships between maternal feeding practices, child weight gain and obesogenic eating behaviors in 2-year-old children. The competing hypothesis that child eating behaviors predict changes in maternal feeding practices was also examined. Methods A sample of 323 mother (mean age = 35 years, ± 0.37 and child dyads (mean age = 2.03 years, ± 0.37 at recruitment were participants. Mothers completed a questionnaire assessing parental feeding practices and child eating behaviors at baseline and again one year later. Child BMI (predominantly objectively measured was obtained at both time points. Results Increases in child BMI z-scores over the follow-up period were predicted by maternal instrumental feeding practices. Furthermore, restriction, emotional feeding, encouragement to eat, weight-based restriction and fat restriction were associated prospectively with the development of obesogenic eating behaviors in children including emotional eating, tendency to overeat and food approach behaviors (such as enjoyment of food and good appetite. Maternal monitoring, however, predicted decreases in food approach eating behaviors. Partial support was also observed for child eating behaviors predicting maternal feeding practices. Conclusions Maternal feeding practices play an important role in the development of weight gain and obesogenic eating behaviors in young children and are potential targets for effective prevention interventions aiming to decrease child obesity.

    2016-07-01

    Full Text Available The effectiveness of exercise training for preventing excessive gestational weight gain (GWG and gestational diabetes mellitus (GDM is still uncertain. As maternal obesity is associated with both GWG and GDM, there is a special need to assess whether prenatal exercise training programs provided to obese women reduce the risk of adverse pregnancy outcomes. Our primary aim was to assess whether regular supervised exercise training in pregnancy could reduce GWG in women with prepregnancy overweight/obesity. Secondary aims were to examine the effects of exercise in pregnancy on 30 outcomes including GDM incidence, blood pressure, blood measurements, skinfold thickness, and body composition.This was a single-center study where we randomized (1:1 91 pregnant women with a prepregnancy body mass index (BMI ≥ 28 kg/m2 to exercise training (n = 46 or control (standard maternity care (n = 45. Assessments were done at baseline (pregnancy week 12-18 and in late pregnancy (week 34-37, as well as at delivery. The exercise group was offered thrice weekly supervised sessions of 35 min of moderate intensity endurance exercise and 25 min of strength training. Seventeen women were lost to follow-up (eight in the exercise group and nine in the control group. Our primary endpoint was GWG from baseline testing to delivery. The principal analyses were done as intention-to-treat analyses, with supplementary per protocol analyses where we assessed outcomes in the women who adhered to the exercise program (n = 19 compared to the control group. Mean GWG from baseline to delivery was 10.5 kg in the exercise group and 9.2 kg in the control group, with a mean difference of 0.92 kg (95% CI -1.35, 3.18; p = 0.43. Among the 30 secondary outcomes in late pregnancy, an apparent reduction was recorded in the incidence of GDM (2009 WHO definition in the exercise group (2 cases; 6.1% compared to the control group (9 cases; 27.3%, with an odds ratio of 0.1 (95% CI 0.02, 0.95; p = 0

    The health care environment still needs knowledge based discovery for handling wealth of data. Extraction of the potential causes of the diseases is the most important factor for medical data mining. Fuzzy association rule mining is wellperformed better than traditional classifiers but it suffers from the exponential growth of the rules produced. In the past, we have proposed an information gain based fuzzy association rule mining algorithm for extracting both association rules and membership functions of medical data to reduce the rules. It used a ranking based weight value to identify the potential attribute. When we take a large number of distinct values, the computation of information gain value is not feasible. In this paper, an enhanced approach, called gain ratio based fuzzy weighted association rule mining, is thus proposed for distinct diseases and also increase the learning time of the previous one. Experimental results show that there is a marginal improvement in the attribute selection process and also improvement in the classifier accuracy. The system has been implemented in Java platform and verified by using benchmark data from the UCI machine learning repository.

    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.

    Full Text Available Abstract Background The impact of excess gestational weight gain (GWG on maternal and child health outcomes is well documented. Understanding how health care providers view and manage GWG may assist with influencing healthy gestational weight outcomes. This study aimed to assess General Practitioner's (GPs perspectives regarding the management and assessment of GWG and to understand how GPs can be best supported to provide healthy GWG advice to pregnant women. Methods Descriptive qualitative research methods utilising semi - structured interview questions to assess GPs perspectives and management of GWG. GPs participating in shared antenatal care in Geelong, Victoria and Sydney, New South Wales were invited to participate in semi - structured, individual interviews via telephone or in person. Interviews were digitally recorded and transcribed verbatim. Data was analysed utilising thematic analysis for common emerging themes. Results Twenty eight GPs participated, 14 from each state. Common themes emerged relating to awareness of the implications of excess GWG, advice regarding weight gain, regularity of gestational weighing by GPs, options for GPs to seek support to provide healthy lifestyle behaviour advice and barriers to engaging pregnant women about their weight. GPs perspectives concerning excess GWG were varied. They frequently acknowledged maternal and child health complications resulting from excess GWG yet weighing practices and GWG advice appeared to be inconsistent. The preferred support option to promote healthy weight was referral to allied health practitioners yet GPs noted that cost and limited access were barriers to achieving this. Conclusions GPs were aware of the importance of healthy GWG yet routine weighing was not standard practice for diverse reasons. Management of GWG and perspectives of the issue varied widely. Time efficient and cost effective interventions may assist GPs in ensuring women are supported in achieving

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.

    The prevalence of being overweight during childhood continues to increase in the USA and Canada and children living in rural areas are more at risk than their urban counterparts. The objectives of this study were to evaluate how well the parent’s perception of their child’s weight status correlated with objectively measured weight status among a group of rural children and to identify predictors of inaccurate parental perceptions of child’s weight status. Participants were children from the Saskatchewan Rural Health Study conducted in 2010. Self-administered questionnaires were distributed through rural schools to parents of children in grades one to eight. Parents reported their child’s height and weight and rated their child’s weight status (underweight, just about the right weight, or overweight). Standardized body mass index (BMI) categories were calculated for clinically measured height and weight and for parental report of height and weight for 584 children. Logistic regression analysis was performed to identify predictors of misclassification of the parent’s perception of child’s weight status adjusting for potential confounders. Clinically measured overweight was much higher (26.5%) compared to parental perceived overweight (7.9%). The misclassification of the child’s BMI was more likely to occur if the child was a boy (odds ratio (OR) = 1.58) or non-Caucasian (OR = 2.03). Overweight was high in this group of rural children and parental perception of weight status underestimated the actual weight status of overweight school-age children. Parental reporting of child weight status has implications for public health policy and prevention strategies. Future research should focus on assessing longitudinal effects of parental misperceptions of child’s weight status. PMID:27527235

    The availability of genetic tests for multifactorial conditions such as obesity raises concerns that higher-risk results could lead to fatalistic reactions or lower-risk results to complacency. No study has investigated the effects of genetic test feedback for the risk of obesity in non-clinical samples. The present study explored psychological and behavioral reactions to genetic test feedback for a weight related gene (FTO) in a volunteer sample (n = 18) using semi-structured interviews. Respondents perceived the gene test result as scientifically objective; removing some of the emotion attached to the issue of weight control. Those who were struggling with weight control reported relief of self-blame. There was no evidence for either complacency or fatalism; all respondents emphasized the importance of lifestyle choices in long-term weight management, although they recognized the role of both genes and environment. Regardless of the test result, respondents evaluated the testing positively and found it motivating and informative. Genetic test feedback for risk of weight gain may offer psychological benefits beyond its objectively limited clinical utility. As the role of genetic counselors is likely to expand, awareness of reasons for genetic testing for common, complex conditions and reactions to the test result is important.
