This report presents the development of the gain weighted eigenspace assignment methodology. This provides a designer with a systematic methodology for trading off eigenvector placement versus gain magnitudes, while still maintaining desired closed-loop eigenvalue locations. This is accomplished by forming a cost function composed of a scalar measure of error between desired and achievable eigenvectors and a scalar measure of gain magnitude, determining analytical expressions for the gradients, and solving for the optimal solution by numerical iteration. For this development the scalar measure of gain magnitude is chosen to be a weighted sum of the squares of all the individual elements of the feedback gain matrix. An example is presented to demonstrate the method. In this example, solutions yielding achievable eigenvectors close to the desired eigenvectors are obtained with significant reductions in gain magnitude compared to a solution obtained using a previously developed eigenspace (eigenstructure) assignment method.

The aim of this review was to summarize the literature regarding the impact of the menopause transition on body weight and body composition. We conducted a search of the literature using Medline (Ovid, 1946-present) and PubMed (1966-2012) for English-language studies that included the following search terms: 'menopause', 'midlife', 'hormone therapy' or 'estrogen' combined with 'obesity', 'body weight' or 'body composition'. Whereas weight gain per se cannot be attributed to the menopause transition, the change in the hormonal milieu at menopause is associated with an increase in total body fat and an increase in abdominal fat. Weight excess at midlife is not only associated with a heightened risk of cardiovascular and metabolic disease, but also impacts adversely on health-related quality of life and sexual function. Animal and human studies indicate that this tendency towards central abdominal fat accumulation is ameliorated by estrogen therapy. Studies mostly indicate a reduction in overall fat mass with estrogen and estrogen-progestin therapy, improved insulin sensitivity and a lower rate of development of type 2 diabetes. The hormonal changes across the perimenopause substantially contribute to increased abdominal obesity which leads to additional physical and psychological morbidity. There is strong evidence that estrogen therapy may partly prevent this menopause-related change in body composition and the associated metabolic sequelae. However, further studies are required to identify the women most likely to gain metabolic benefit from menopausal hormone therapy in order to develop evidence-based clinical recommendations.

The total amounts of fat in a fast food menu consisting of French fries and fried Chicken Nuggets from McDonald's and KFC, respectively, bought in 35 different countries vary from 41 to 71 gram. In most countries the menu contained unacceptably high amounts of industrially-produced trans fat which contributes to an increased risk of ischaemic heart disease, weight gain, abdominal fat accumulation and type 2 diabetes. The quality of the ingredients in fast food ought to be better and the size of the portions smaller and less energy-dense so that frequent fast food meals do not increase the risk of obesity and diseases among customers.

Pregnancy is frequently followed by the development of obesity. Aside from psychological factors, hormonal changes influence weight gain in pregnant women. We attempted to assess the potential association between personality type and the extent of gestational weight gain. The study group involved 773 women after term delivery (age 26.3 ± 3.9 years, body mass before pregnancy 61.2 ± 11.1 kg). Weight gain during pregnancy was calculated by using self-reported body mass prior to and during the 38th week of pregnancy. Personality type was assessed using the Polish version of the Framingham Type A Behavior Patterns Questionnaire (adapted by Juczynski). Two hundred forty-six (31.8%) study subjects represented type A personalities, 272 (35.2%) type B and 255 (33.0%) an indirect type. Gestational weight gain was related to the behavior patterns questionnaire score and age. In women type A personality, the weight gain was higher than in women with type B behavior of the same age. In women >30, the gestational weight gain was larger for type B personalities. Type A personality and increased urgency in younger pregnant women increases the risk of developing obesity during pregnancy in women below 30 years old. A higher level of competitiveness demonstrates a risk factor of excessive weight gain during pregnancy regardless of age.

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. Copyright © 2011 Elsevier B.V. All rights reserved.

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.

regnancy and the postpartum period are unique opportunities to promote healthy lifestyle choices including a healthy diet and regular exercise. This is especially important for those who are overweight or obese. Women are weighed at their first antenatal visit and body mass index (BMI) calculated, but not all hospitals routinely weigh women throughout pregnancy. A qualitative Dublin study examined experiences of routine weighing during antenatal care. This study found that women expected to be weighed during pregnancy and postpartum. The benefits of this included providing reassurance and minimising postpartum weight retention. Furthermore, women were eager to receive more information about healthy lifestyle interventions and gestational weight gain (GWG) from healthcare professionals

Weight gain during pregnancy affects obesity risk in offspring. To assess weight gain among UW Health prenatal patients and to identify predictors of unhealthy gestational weight gain. Retrospective cohort study of women delivering at UW Health during 2007-2012. Data are from the UW eHealth Public Health Information Exchange (PHINEX) project. The proportion of women with excess and insufficient (ie, unhealthy) gestational weight gain was computed based on 2009 Institute of Medicine guidelines. Multivariable logistic regression was used to identify risk factors associated with excess and insufficient gestational weight gain. Gestational weight gain of 7,385 women was analyzed. Fewer than 30% of prenatal patients gained weight in accordance with Institute of Medicine guidelines. Over 50% of women gained excess weight and 20% gained insufficient weight during pregnancy. Pre-pregnancy weight and smoking status predicted excess weight gain. Maternal age, race/ethnicity, smoking status, and having Medicaid insurance predicted insufficient weight gain. Unhealthy weight gain during pregnancy is the norm for Wisconsin women. Clinical and community interventions that promote healthy weight gain during pregnancy will not only improve the health of mothers, but also will reduce the risk of obesity in the next generation.

Factors associated with weight gain during pregnancy that may be linked to maternal overweight and obesity were examined. In this observational study, 144 women reported on demographics, (prepregnancy) body weight, and lifestyles in self-reported questionnaires at 30 weeks gestation. Body weight at the end of pregnancy (self-reported at 6 weeks postpartum) was used to determine total gestational weight gain. Multivariate prediction models were developed to identify factors associated with total gestational weight gain and excessive gestational weight gain (i.e., higher weight gain than recommended by the Institute of Medicine). Women gained 14.4 (+/-5.0) kg during pregnancy. Obese women gained almost 4 kg less than normal weight women. Pregnant women judging themselves to be less physically active or women who reported increased food intakes during pregnancy gained significantly more weight. Over one third of women (38%) gained more weight than recommended. Being overweight, judging yourself to be less physically active than others, and a perceived elevated food intake during pregnancy were significantly associated with excessive weight gain (odds ratio [OR] = 6.33, 95% confidence interval [CI]: 2.01-19.32; OR = 3.96, 95% CI: 1.55l, 10.15; and OR = 3.14, 95% CI: 1.18, 8.36, respectively). A higher age at menarche and hours of sleep reduced the odds for excessive weight gain (OR = 0.75, 95% CI: 0.57, 0.99; and OR = 0.35, 95% CI: 0.57, 0.93, respectively). Mean hours of sleep, perceived physical activity, and measures of food intake at 30 weeks gestation were identified as modifiable behavioral correlates for excessive gestational weight gain. Strategies to optimize gestational weight gain need to be explored, with a focus on the identified factors.

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.

The origin of weight gain after functional surgery for Parkinson's disease (PD) is incompletely known. We have done a prospective study to determine the possible causes of weight gain after pallidal and subthalamic surgery. Twenty-seven patients were studied (9 unilateral pallidotomy, 9 bilateral deep brain stimulation (DBS) of palidum, and 9 bilateral DBS of suthalamic nucleus) with a follow-up of 12 months. The relationship between weight gain and changes in motor situation, levodopa dosage, dyskinesias, dysphagia and mood state were analyzed. The patients filled a questionnaire about the severity and etiology of weight gain. Weight gain was noted in 26 patients (mean of 4.7 kg at 12 months). It was found a significant correlation between weight gain and improvement of dyskinesias (AIMS) (r = 0.461; p = 0.023), the scores of the UPDRS part III, (r = 0.479; p = 0.028), and a significant inverse correlation with the pre-operative weight of the patient (r = 0.399; p = 0.050). Weight gain was most pronounced with bilateral than unilateral pallidal surgery (p = 0.021). The majority of patients referred weight gain as an slight adverse event and secondary to the improvement of dyskinesias. Functional surgery for PD, independently of the surgical target, provokes weight gain which is benign in the majority of cases. Reduction of energy expenditure with respect to the pre-operative situation would be the responsible of that phenomenon.

To examine the influence of health behaviours and psychological well-being on gestational weight gain using a biopsychosocial model. A prospective cohort study of pregnant women consecutively recruited at their first antenatal care visit. A self-administered questionnaire was used to collect data on health behaviours and psychological well-being in early pregnancy. Linear regression and logistic regression were used to identify predictors of total weight gain in kilograms and weight gain outside the current Institute of Medicine recommendations, respectively. A maternity hospital in the Republic of Ireland. Data on 799 women were analysed. Pre-pregnant BMI ≥30·0 kg/m2, short stature, parity >0, decreased food intake and absence of health insurance predicted lower absolute gestational weight gain, while foreign nationality, consumption of takeaway meals more than once weekly and increased food intake predicted higher absolute gestational weight gain. Overweight and obesity, foreign nationality, increased food intake and height >170 cm were risk factors for excessive weight gain, while antenatal depression was protective against excessive weight gain. Notably, physical activity measures were not related to the gestational weight gain outcomes. Pre-pregnancy overweight and increased food intake were the strongest predictors of excessive gestational weight gain. None of the psychological well-being measures examined, with the exception of antenatal depression, was associated with any of the weight gain outcomes. The behavioural predictors of gestational weight gain were increased food intake and takeaway consumption. Public health promotions should target pre-pregnancy BMI and pregnancy-associated change in food intake.

To examine the association of physical fitness, sports participation, physical activity and sedentary behavior as well as dietary patterns and family background with weight gain in non-overweight elementary school children, independent of absolute body weight. Height, weight, and physical fitness were assessed in 1249 (51% male) children in south-west Germany during the fall of 2010 and 2011 (age at baseline: 7.0±0.6years). Based on changes in body mass index percentiles children were classified into a weight loss, constant weight, or weight gain group. Health behavior and family background were assessed via parent questionnaire. Group differences were examined via analysis of variance and multinomial logistic regression. Weight gain was associated with low physical activity, lack of active transport, and lack of regular breakfast at follow-up. Children in the weight gain category also displayed lower fitness during baseline and follow-up, but differences were more pronounced during follow-up. TV time, migration background or parental education was not associated with weight gain. Ensuring adequate physical activity and high fitness is an important aspect in the prevention of excessive weight gain during childhood. In addition to sports participation active transport should be emphasized in future weight management programs in children. Copyright © 2013 Elsevier Inc. All rights reserved.

Objective The objective of this study was to estimate the proportion of pregnant women with systemic lupus erythematosus meeting Institute of Medicine guidelines for gestational weight gain and determine correlates of adherence to guidelines. Methods Singleton, live births in the Hopkins Lupus Pregnancy Cohort 1987-2015 were included. Pre-pregnancy weight was the weight recorded 12 months prior to pregnancy/first trimester. Final weight was the last weight recorded in the third trimester. Adherence to Institute of Medicine guidelines (inadequate, adequate, or excessive) was based on pre-pregnancy body mass index. Fisher's exact test and analysis of variance determined factors associated with not meeting guidelines. Stepwise selection estimated predictors of gestational weight gain. Results Of the 211 pregnancies, 34%, 24% and 42% had inadequate, adequate and excessive gestational weight gain, respectively. In exploratory analyses, differences in Institute of Medicine adherence were observed by pre-pregnancy body mass index, race, elevated creatinine during pregnancy and pre-pregnancy blood pressure. Odds of inadequate and excessive gestational weight gain increased 12% with each 1 kg/m 2 increase in pre-pregnancy body mass index. Lower maternal education was associated with increased odds of inadequate and excessive gestational weight gain. Conclusions As in the general population, most women with systemic lupus erythematosus did not meet Institute of Medicine guidelines. Our results identified predictors of gestational weight gain to aid in targeted interventions to improve guideline adherence in this population.

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

Research in normal weight individuals paradoxically suggests that measures of attempted eating restriction might represent robust predictors of weight gain. This review examined the extent to which measures of dieting (e.g., self-reported weight loss dieting in the past year) and dietary restraint (e.g., the Cognitive Restraint scale from the Three-Factor Eating Questionnaire) have prospectively predicted weight change. We located and reviewed 25 prospective studies containing 40 relevant comparisons. Studies were limited to those in which participants were non-obese (with a mean BMI between 18.5 and 30) and averaged at least 12 years old. Neither measure predicted future weight loss. Fifteen of the 20 comparisons (75%) that examined measures of dieting significantly predicted future weight gain whereas only 1 of 20 (5%) that examined restrained eating measures did so. Two plausible explanations for these findings are that: (1) dieters and restrained eaters do not differ in terms of an underlying proneness toward weight gain, but restrained eating represents a more effective means of preventing it; and (2) normal weight individuals who diet do so because they are resisting a powerful predisposition toward weight gain which dieting ultimately fails to prevent. Recent dieting in non-obese individuals may be a valuable proxy of susceptibility to weight gain. This easily assessed characteristic could identify individuals for whom obesity prevention interventions would be particularly appropriate. PMID:24032024

To examine the association between weight gain since menopause and weight regain after a weight loss program. Participants were 19 obese women who participated in a 15-week weight loss program and a 12-month follow-up. Main outcomes were: body composition, resting metabolic rate, energy intake, energy expenditure, and weight regain at follow-up. All body composition measures significantly decreased after intervention (all P ≤ 0.01) while all measures of fatness increased significantly after the 12-month follow-up (P ≤ 0.01). Body weight gain since menopause was associated with body weight regain (r = 0.65; P = 0.003) after follow-up even after adjustment for confounders. Weight gain since menopause is associated with body weight regain following the weight loss program. Therefore, weight gain since menopause should be considered as a factor influencing weight loss maintenance in older women.
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.

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. Copyright 2005 Movement Disorder Society.

Full Text Available The present article is an attempt to perceive the universal sustainability observable in an individual country or region, where the religious, political, social-demographic, economic, environmental, creative, technological and investment subsystems are revealed not only through the vitality of spiritual and material existence media, but rather through the signs of the development of these subsystems as self-assembled units through the erosion of their interaction. The problem of optimal allocation of investment resources among the separate sustainability’s subsystems was addressed by means of expert methods and techniques of portfolio methodology which will enable the achievement of the enshrined universal sustainability standards. A country-specific index composition of sustainability subsystems’ indices was chosen as the universal sustainability index for the specific country. The index in its dynamics is perceived as a random process. While projecting its state and evaluating its power, i.e., the impact of the subsystem efficiency in a particular moment, this power is measured by the level of the index and the reliability or guarantee of an appropriate level. To solve the problem of investment resources allocation, the idea of Markowitz Random Field was invoked in order to reach the maximum power of sustainability index while applying the technical solution—the so-called “GoldSim” system. Engineering is a methodology that aspires to reveal the core attributes of complex systems and instruments in order to manage the possibility to influence these properties for the systems. Experimental expert evaluation and case study is performed on Lithuanian data.

ABSTRACT: BACKGROUND: Antipsychotic-induced weight gain constitutes a major unresolved clinical problem which may ultimately be associated with reducing life expectancy by 25 years. Overweight is associated with brain deterioration, cognitive decline and poor quality of life, factors which...... are already compromised in normal weight patients with schizophrenia. Here we outline the current strategies against antipsychotic-induced weight gain, and we describe peripheral and cerebral effects of the gut hormone glucagon-like peptide-1 (GLP-1). Moreover, we account for similarities in brain changes...... between schizophrenia and overweight patients. DISCUSSION: Current interventions against antipsychotic-induced weight gain do not facilitate a substantial and lasting weight loss. GLP-1 analogues used in the treatment of type 2 diabetes are associated with significant and sustained weight loss...

In a treatment-effect framework using Add Health data, we investigate whether adolescents gain weight when increasingly exposed to obesity in their social networks. We find that weight gain can be a reaction to an increase, but not a decrease, in exposure to obesity that is based on social ties, not geographic proximity. Taking an endogenous growth perspective on the prevalence of obesity, we thus attempt to reveal a mechanism through which obesity may potentially develop into a sweeping epid...

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...

Existing evidence suggests that the prevalence of overweight and obesity among prisoners in different settings is high. Evaluating weight change during incarceration would allow for the investigation of whether the prison environment indeed contributes to unfavourable weight changes. This study aimed to do a systematic review and a meta-analysis of existing evidence regarding weight change during incarceration. We conducted a systematic literature search by using five different online databases and included grey literature. A total of 16 studies, all conducted in developed countries, were identified. Weight change was computed in 11 of these studies and was self-reported in five studies. Only two studies included youth. In all but 1 of the 11 studies using actual assessment of weight change, there was an increase in body weight or body mass index on average or weight gain occurred among a significant proportion of participants. A meta-analysis of eight of these studies showed an average weight gain of 0.43 (95% CI 0.14, 0.72) lb/week. In all studies including perceived weight change, a high proportion (43% to 73%) of participants reported weight gain during incarceration. Health promotion activities within prisons should incorporate initiatives aimed at combating unhealthy weight developments. © 2017 World Obesity Federation.

Conclusion: Younger women, women who were obese at diagnosis, women with more than 36 months since diagnosis, or women who showed lower diet quality should be considered at high-risk for weight gain. Findings from our study suggest that optimal weight management strategies should be developed using ethnically- or culturally-appropriate approaches.

Physiologic studies suggest that sleep restriction has metabolic effects that predispose to weight gain. The authors investigated the association between self-reported usual sleep duration and subsequent weight gain in the Nurses' Health Study. The 68,183 women who reported habitual sleep duration in 1986 were followed for 16 years. In analyses adjusted for age and body mass index, women sleeping 5 hours or less gained 1.14 kg (95% confidence interval (CI): 0.49, 1.79) more than did those sleeping 7 hours over 16 years, and women sleeping 6 hours gained 0.71 kg (95% CI: 0.41, 1.00) more. The relative risks of a 15-kg weight gain were 1.32 (95% CI: 1.19, 1.47) and 1.12 (95% CI: 1.06, 1.19) for those sleeping 5 and 6 hours, respectively. The relative risks for incident obesity (body mass index: >30 kg/m(2)) were 1.15 (95% CI: 1.04, 1.26) and 1.06 (95% CI: 1.01, 1.11). These associations remained significant after inclusion of important covariates and were not affected by adjustment for physical activity or dietary consumption. These data suggest that short sleep duration is associated with a modest increase in future weight gain and incident obesity. Further research is needed to understand the mechanisms by which sleep duration may affect weight.

We determined body weight increase in first year Dutch college students. We had the objective to determine whether the awareness of the unhealthy lifestyle raised concerns and willingness to change habits. Body weight, heartbeat, BMI, body fat percentages, and blood pressure values were collected from 1095 students. Comprehensive statistical analysis was performed on the data. The students had a mean weight gain of 1.1 kg and an average BMI gain of 0.35. Members of a student corps gained significantly more weight (1.6 ± 3.1 kg) than non-members (1.0 ± 2.5 kg), while students who are living independently gained an average of 0.5 kg more than students living with their parents (p < 0.05). Approximately 40% of the students changed their eating patterns and 30.7% of the students consumed more alcohol. Students experienced hindrance in physical exercise and mental well-being. Students with a high BMI without irregular eating habits were willing to change their lifestyle. However, students who had irregular lifestyles exhibited the lowest willingness to change their eating behaviors and to lose weight. Our study provides insight into means by which adolescents at high risk for weight gain can be approached to improve experienced quality of life.

This narrative review discusses gestational weight gain (GWG) and medical outcomes of pregnancy, including metabolic, cardiovascular, respiratory, musculoskeletal and psychiatric systems. Taken as a whole, the available evidence shows that excessive GWG increases the risk of all medical complications of pregnancy, and negatively impacts the long-term health and weight of both mothers and their offspring. Briefly, interventions to encourage appropriate GWG are discussed and readers are directed to resources to facilitate discussion of pregnancy weight.

Prior research makes competing predictions regarding whether marital satisfaction is positively or negatively associated with weight gain. The health regulation model suggests that satisfying relationships facilitate the functions of marriage that promote health. Thus, spouses should be most likely to gain weight when either partner is less satisfied because marital strain causes stress that interferes with self-regulatory behaviors. The mating market model, in contrast, suggests that weight maintenance is motivated primarily by the desire to attract a mate. Thus, spouses should be least likely to gain weight when either partner is less satisfied because they should feel an increased need to attract a new mate. This longitudinal study of 169 newlywed couples evaluated each possibility. Spouses completed measures of height, weight, marital satisfaction, stress, steps toward divorce, and several covariates biannually for 4 years. Supporting the mating market model, own and partner satisfaction were positively associated with changes in weight, and this association was mediated by steps toward divorce: Spouses who were less satisfied than usual or had partners who were less satisfied than usual were more likely to consider divorce and thus less likely to gain weight. These findings challenge the idea that quality relationships always benefit health, suggesting instead that spouses in satisfying relationships relax their efforts to maintain their weight because they are no longer motivated to attract a mate. Interventions to prevent weight gain in early marriage may therefore benefit from encouraging spouses to think about their weight in terms of health rather than appearance.

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.
On day 15, the proportions of HIV-positive and HIV-negative children who had sustained weight gain were not significantly different. Conclusion. Chronically malnourished children with superimposed SAM benefit from the use of RUTF as much as children without chronic nutritional deprivation, regardless of HIV status.

Background Excessive weight gain during pregnancy is associated with multiple maternal and neonatal complications. However, interventions to prevent excessive weight gain during pregnancy have not been adequately evaluated. Objectives To evaluate the effectiveness of interventions for preventing excessive weight gain during pregnancy and associated pregnancy complications. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (20 October 2011) and MEDLINE (1966 to 20 October 2011). Selection criteria All randomised controlled trials and quasi-randomised trials of interventions for preventing excessive weight gain during pregnancy. Data collection and analysis We assessed for inclusion all potential studies we identified as a result of the search strategy. At least two review authors independently assessed trial quality and extracted data. We resolved discrepancies through discussion. We have presented results using risk ratio (RR) for categorical data and mean difference for continuous data. We analysed data using a fixed-effect model. Main results We included 28 studies involving 3976 women; 27 of these studies with 3964 women contributed data to the analyses. Interventions focused on a broad range of interventions. However, for most outcomes we could not combine data in a meta-analysis, and where we did pool data, no more than two or three studies could be combined for a particular intervention and outcome. Overall, results from this review were mainly not statistically significant, and where there did appear to be differences between intervention and control groups, results were not consistent. For women in general clinic populations one (behavioural counselling versus standard care) of three interventions examined was associated with a reduction in the rate of excessive weight gain (RR 0.72, 95% confidence interval 0.54 to 0.95); for women in high-risk groups no intervention appeared to reduce excess weight gain.

Antibiotics, prebiotics and probiotics are widely used as growth promoters in agriculture. In the 1940s, use of Streptomyces aureofaciens probiotics resulted in weight gain in animals, which led to the discovery of chlortetracycline. Tetracyclines, macrolides, avoparcin and penicillins have been commonly used in livestock agriculture to promote growth through increased food intake, weight gain, and improved herd health. Prebiotic supplements including oligosaccharides, fructooligosaccharides, and galactosyl-lactose improve the growth performance of animals. Probiotics used in animal feed are mainly bacterial strains of Gram-positive bacteria and have been effectively used for weight gain in chickens, pigs, ruminants and in aquaculture. Antibiotics, prebiotics and probiotics all modify the gut microbiota and the effect of a probiotic species on the digestive flora is probably determined by bacteriocin production. Regulations governing the introduction of novel probiotics and prebiotics vary by geographical region and bias is very common in industry-funded studies. Probiotic and prebiotic foods have been consumed for centuries, either as natural components of food, or as fermented foods and it is possible to cause the same weight gain effects in humans as in animals. This review presents the use of growth promoters in food-producing animals to influence food intake and weight gain. Copyright © 2016 Elsevier Ltd. All rights reserved.

Prior studies of immigrants to the United States show significant weight gain after 10 years of US residence. Pediatric refugees are a vulnerable population whose post-immigration weight trajectory has not been studied. We examined the longitudinal weight trajectory of 1067 pediatric refugees seen in a single university based refugee health program between the dates of September 3, 2012 and September 3, 2014 to determine how quickly significant weight gain occurs post-arrival. The most recent BMI was abstracted from the electronic health record and charts reviewed to obtain serial BMI measurements in 3 year increments after the date of US arrival. The mean arrival BMI percentile for all refugees was 47th percentile. This increased significantly to the 63rd percentile within 3 years of US arrival (p refugees. The overall prevalence of age and sex adjusted obesity rose from 7.4 % at arrival to 18.3 % within 9 years of US immigration exceeding the pediatric US national obesity prevalence of 16.9 %. Pediatric refugees are at increased risk of rapid weight gain after US immigration. Targeted interventions focused on prevention of weight gain in specific populations are warranted.

To determine whether weight loss could reverse excessive sleep in high-fat diet-induced obesity. Three groups of mice participated in the study. A weight gain/loss group was fed with high-fat food for 6 weeks (weight gain), and regular food again for 4 weeks (weight loss). A control group and a weight gain only group were fed with regular food and high-fat food, respectively, for 10 weeks after the baseline. Adult male C57BL/6 mice. The amounts of wake, rapid eye movement sleep (REMS) and non-REM sleep (NREMS) were determined at week 0 (baseline), week 6, and week 10. The weight gain/loss group displayed a significant decrease in wakefulness and increases in NREMS and episodes of NREMS during 6 weeks of weight gain, which were reversed during subsequent 4 weeks of weight loss. The weight gain only group displayed significant decrease in wakefulness and increase of NREMS and REMS at both week 6 and week 10. The control group did not show significant sleep alterations during the experiment. These observations indicate that sleep alterations induced by weight gain are reversed by weight loss in obese animals. These data may shed light on the mechanisms underlying the well-established association between obesity and sleepiness in humans and may lead to new therapeutic strategies for these 2 increasingly prevalent problems in the modern societies.

We have established an animal model for olanzapine-induced body weight gain, and used it to explore the relation between this weight gain, excessive food consumption, gross motor activity, and macronutrient choice. Female Sprague-Dawley rats received olanzapine (OLAN) or diluent (1.2mg/kg per day) via gavage for 10 days. Rats receiving OLAN exhibited significant increases in body weight when compared with control rats. Body weight returned to control levels once OLAN treatment was discontinued. Food consumption among the OLAN-treated group was significantly greater than among control rats between 6 and 10 days of treatment. Between 4 and 10 days of treatment, feed efficiency (grams of weight gained/grams of food consumed) was also significantly greater among animals receiving OLAN. In contrast, chronic administration of haloperidol (0.04mg/kg; q.d.; gavage) did not influence body weight or food consumption of treated rats. Gross motor activity was significantly reduced by OLAN between 1 and 10 days of treatment, also returning to control levels when treatment was discontinued. No significant changes were observed in brain DA, DOPAC, HVA or 5-HIAA among animals receiving OLAN daily for 30 days; however, 5-HT levels were significantly elevated. In contrast, acute (1.2mg/kg; 2h; i.p.) administration of OLAN significantly increased brain DOPAC and HVA levels without affecting those of 5-HT or 5-HIAA. OLAN (1.2mg/kg; q.d.; 10 days) administration did not alter macronutrient choice (carbohydrate:protein ratio) of rats. These data show that an animal model of OLAN-induced weight gain is readily generated, and suggest that the weight gain results at least in part from increased food intake, reduced gross motor activity, and enhanced feed efficiency.

Preterm births occur among 11.4% of all live infant births. Without steady weight gain, premature infants may experience lengthy hospitalizations, neurodevelopmental deficits and hospital readmissions, which can increase the financial burden on the health care system and their families. The total U.S. health-related costs linked to preterm infant deliveries are estimated at $4.33 billion. Kangaroo care is a feasible practice that can improve preterm infant weight gain. However, this intervention is utilized less often throughout the U.S. due to numerous barriers including a lack of consistent protocols, inadequate knowledge, and decreased level of confidence in demonstrating the proper kangarooing technique. An integrative review was conducted to evaluate the impact of kangaroo care on premature infant weight gain in order to educate nurses about its efficacy among preterm infants. A literature search was conducted using CINAHL, PubMed, Cochrane Reviews, ClinicalKey and Google Scholar. Large volume searches were restricted using appropriate filters and limiters. Most of the evaluated studies determined that weight gain was greater among the kangarooing premature infants. Kangaroo care is a low-tech low-cost modality that can facilitate improved preterm infant weight gain even in low-resource settings. Despite its current efficacy, kangaroo care is not widely utilized due to several barriers including an absence of standardized protocols and a lack of knowledge about its benefits. Kangaroo care can become a widespread formalized practice after nurses and parents learn about the technique and its numerous benefits for premature infants, including its association with improved weight gain.

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.

This study described the nutritional status of 228 pregnant women and the influence of this on birth weight. 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 (ppregnant women who began the pregnancy 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.

Psychotropic drugs can induce substantial weight gain, particularly during the first 6 months of treatment. The authors aimed to determine the potential predictive power of an early weight gain after the introduction of weight gain-inducing psychotropic drugs on long-term weight gain. Data were obtained from a 1-year longitudinal study ongoing since 2007 including 351 psychiatric (ICD-10) patients, with metabolic parameters monitored (baseline and/or 1, 3, 6, 9, 12 months) and with compliance ascertained. International Diabetes Federation and World Health Organization definitions were used to define metabolic syndrome and obesity, respectively. Prevalences of metabolic syndrome and obesity were 22% and 17%, respectively, at baseline and 32% and 24% after 1 year. Receiver operating characteristic analyses indicated that an early weight gain > 5% after a period of 1 month is the best predictor for important long-term weight gain (≥ 15% after 3 months: sensitivity, 67%; specificity, 88%; ≥ 20% after 12 months: sensitivity, 47%; specificity, 89%). This analysis identified most patients (97% for 3 months, 93% for 12 months) who had weight gain ≤ 5% after 1 month as continuing to have a moderate weight gain after 3 and 12 months. Its predictive power was confirmed by fitting a longitudinal multivariate model (difference between groups in 1 year of 6.4% weight increase as compared to baseline, P = .0001). Following prescription of weight gain-inducing psychotropic drugs, a 5% threshold for weight gain after 1 month should raise clinician concerns about weight-controlling strategies. © Copyright 2015 Physicians Postgraduate Press, Inc.

The objective of this study was to examine the associations of sleep duration with subsequent weight and major weight gain in women and men during a follow-up period of 5-7years. The data were derived from the Helsinki Health Study cohort mail questionnaire surveys among 40-60-year-old employees of the City of Helsinki, Finland. At baseline in 2000-2002, 8960 people responded to the survey (80% women, response rate 67%). The follow-up survey was conducted in 2007 among all respondents to the baseline survey (n=7332, response rate 83%). Sleep duration (5h or less up to 10h or more) and weight and weight gain of at least 5kg were based on self-reports. Analyses of variance and logistic regression analyses were used to examine the associations between sleep duration and weight, as well as major weight gain. Short sleep duration was associated with major weight gain [odds ratio (OR) 1.52; 95% confidence interval (CI) 1.08, 2.14] during the follow-up. Adjusting for several covariates had only minor effects on that association. Long sleep duration was associated with major weight gain after adjusting for age (OR 1.35; 95% CI 1.00-1.81). No associations were found among men. Sleep duration was associated with major weight gain among middle-aged employed women. Short sleep may be a risk factor for subsequent weight gain. © 2010 European Sleep Research Society.

This article examines the relationship between weight gain and childhood teasing in children. Anthropometric data and self-reported teasing experiences were collected on a sample of second and third graders at a local elementary school in a disadvantaged suburban community. The study model uses bio-ecological development theory in which child development is understood in context: the child's physical characteristics influence the social environment, which interact and influence the behaviors that result in physical development and characteristics such as weight gain. Results suggest that teasing influences BMI change and that the relationship is more complex than simply stating that obese children are teased. Copyright © 2014 Elsevier Inc. All rights reserved.

Breast-feeding is considered to offer optimal nutrition for healthy infant growth and development. Observational studies have linked breast-feeding to reduced obesity. CASE OBSERVATION: We observed an infant who was born macrosomic (4.56 kg) and showed excessive weight gain markedly exceeding the 97th percentile of weight during full breast-feeding. At the age of 4 months, the weight was greater than 11 kg. Clinical evaluation did not reveal any underlying pathology. After the introduction of complementary feeding and hence reduction of the breast milk intake, the excessive weight gain was attenuated and the slope of the percentile curve paralleled upper percentiles. Since this pattern suggested full breast-feeding as the driver of excessive weight gain, we analyzed the human milk composition at the infant age of 1 year and compared the results with published data on composition at this stage of lactation. The milk contents of lactose, fat, fatty acids, polar lipids, carnitine species, and insulin were similar to the reference data. The adiponectin content was increased. The most remarkable alteration was a high milk protein content (mean 1.25 g/dl, reference 0.8 g/dl). A very high protein supply in infancy has been previously shown to increase plasma concentrations of the growth factors insulin and IGF-1, weight gain, and later obesity. We speculate that interindividual variations in human milk adiponectin and protein contents may contribute to modulation of the growth of fully breast-fed infants and in this case may have contributed to excessive weight gain during full breast-feeding. This hypothesis merits being tested in future cohort studies. © 2014 S. Karger AG, Basel.

To investigate the effect of birth weight and early weight gain on the timing of various measures of puberty in both girls and boys. A total of 856 newborns enrolled in the North Carolina Infant Feeding Study were followed to age 5 years, with 600 children followed up at adolescence. Birth weight was obtained from medical records and children were weighed at study visits until age 5 years; gains in standardized weights were calculated over four early age intervals: 0-6 months, 6-12 months, 1-2 years and 2-5 years. Age at menarche in girls and age at advanced Tanner stages in both girls and boys were reported by adolescents and their parents. Survival models were used to analyse the effects of birth weight and early weight gain on these outcomes. Girls with higher birth weight and greater weight gains during the four early age intervals were younger when they reached menarche and advanced Tanner stages; boys with greater early weight gains also were younger when they reached advanced Tanner stages, but few of these effects were statistically significant. Higher birth weights and greater weight gains during infancy and early childhood can lead to earlier sexual maturation in girls. Published 2012.

Conclusions: Students experienced hindrance in physical exercise and mental well-being. Students with a high BMI without irregular eating habits were willing to change their lifestyle. However, students who had irregular lifestyles exhibited the lowest willingness to change their eating behaviors and to lose weight. Our study provides insight into means by which adolescents at high risk for weight gain can be approached to improve experienced quality of life.

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.

Adenotonsillectomy (TA), performed for obstructive sleep apnea (OSA) or recurrent tonsillitis (RT), has been associated with weight gain after surgery. The objective of this study was to look at a large population of children undergoing TA and the demographic factors that contribute to postoperative weight gain. Case series with retrospective chart review. Tertiary, urban academic care center. Children undergoing TA at an academic center between 2008 and 2011 were included in this study. Demographic data (age, gender, race), OSA disease severity, preoperative and 3- to 6-month postoperative normalized body mass index (BMI; z-scores), and changes in z-scores were compared. Complete weight data after TA were available for 115 children, 85 of whom underwent surgery for OSA. Mean age (7.2 ± 4.3 vs 7.3 ± 4.4 years, P = .955) and gender distribution (38% female vs 50% male; P = .323) were similar for the OSA and RT groups. However, children with OSA were more likely to be black (60% vs 33%) than RT patients (P = .026). Overall, the preoperative BMI z-score increased from 0.98 ± 1.50 to 1.21 ± 1.25 (P = .0009) with no difference by surgical indication (P = .58). Multiple linear regression analysis demonstrated that only age was significantly, and negatively, associated with changes in BMI z-scores (P = .015). Similar to previous studies, children had weight gain after TA. In this analysis, younger age (≤ 6 years) was a significant predictor of postoperative weight gain. Future research should prospectively evaluate the association between weight gain and demographic factors in children undergoing TA, with special attention to the relationship with age.

Nutrition is an important regulator of the tempo of growth and obesity is usually associated with tall childhood stature and earlier pubertal development. Several longitudinal studies have demonstrated that timing of puberty is most closely linked to infancy weight gain: suggesting an early window for programming of growth and development. Earlier puberty in the UK MRC 1946 birth cohort was related to smaller size at birth and rapid growth between 0 and 2 years. Rapid early weight gain leads to taller childhood stature and higher insulin-like growth factor I (IGF-I) levels, possibly through early induction of growth hormone (GH) receptor numbers, and such children are also at risk of childhood obesity. In the Avon Longitudinal Study of Parents and Children, rapid infancy weight gain was associated with increased risk of obesity at 5 and 8 years, with evidence of insulin resistance, exaggerated adrenarche and reduced levels of sex hormone binding globulin (SHBG). Potentially the elevated IGF-I and adrenal androgen levels, increased aromatase activity and increased 'free' sex steroid levels consequent to lower SHBG levels could all promote activity of the GnRH pulse generator. In addition obese children have higher leptin levels, a proven permissive factor in initiating LH pulsatility. Obesity could also affect the rate of progression through puberty as nutrition and SHBG may act respectively as an accelerator and brake on peripheral sex steroid action. Early weight gain and early pubertal development might also be associated with loss of the pubertal growth spurt perhaps through obesity-related suppression of GH secretion. Trans-generational recurrence of low birth weight, early catch-up weight gain, earlier menarche, and shorter adult stature have been observed in women, and could contribute to the strong heritability in age at menarche.

Context No research has been conducted on bicycle riding and weight control in comparison to walking. Objective To assess the association between bicycle riding and weight control in premenopausal women. Design, Setting, and Participants This was a 16-year follow-up of 18, 414 women in the Nurses’ Health Study II. Main Outcome Measures Weight change between 1989 and 2005 was the primary outcome and odds of gaining >5% of baseline body weight (BBW) by 2005 the secondary outcome. Results At baseline, only 39% walked briskly while only 1.2% bicycled for ≥30 min/d. For a 30 min/d increase in activity between 1989 and 2005, weight gain was significantly less for brisk walking (−1.81 kg; 95% confidence interval (CI) = −2.05,−1.56), bicycling (−1.59 kg; 95%CI= −2.09, −1.08), and other activities (−1.45 kg; 95%CI= −1.66, −1.24) but not for slow walking (+0.06 kg; 95%CI= −0.22, 0.35). Women who reported no bicycling in 1989 and increased to as little as 5 minutes/day in 2005 gained less weight (−0.74 kg; 95%CI= −1.41, −0.07, P-trend5% of their BBW (Odds Ratio (OR) =0.74, 95%CI=0.56–0.98) compared with those who reported no bicycling; overweight/obese women had lower odds at 2–3 hours/week (OR=0.54, 95%CI=0.34–86). Conclusions Bicycling, similar to brisk walking, is associated with less weight gain and an inverse dose-response relationship exists, especially among overweight/obese women. Future research should focus on brisk walking but also on greater time spent bicycling. PMID:20585071

Background: Body weight in lower animals and humans is highly stable despite a very large flux in energy intake and expenditure over time. Conversely, the existence of higher-than-average variability in weight may indicate a disruption in the mechanisms responsible for homeostatic weight regulation. Objective: In a sample chosen for weight-gain proneness, we evaluated whether weight variability over a 6-mo period predicted subsequent weight change from 6 to 24 mo. Design: A total of 171 nonobese women were recruited to participate in this longitudinal study in which weight was measured 4 times over 24 mo. The initial 3 weights were used to calculate weight variability with the use of a root mean square error approach to assess fluctuations in weight independent of trajectory. Linear regression analysis was used to examine whether weight variability in the initial 6 mo predicted weight change 18 mo later. Results: Greater weight variability significantly predicted amount of weight gained. This result was unchanged after control for baseline body mass index (BMI) and BMI change from baseline to 6 mo and for measures of disinhibition, restrained eating, and dieting. Conclusions: Elevated weight variability in young women may signal the degradation of body weight regulatory systems. In an obesogenic environment this may eventuate in accelerated weight gain, particularly in those with a genetic susceptibility toward overweight. Future research is needed to evaluate the reliability of weight variability as a predictor of future weight gain and the sources of its predictive effect. The trial on which this study is based is registered at clinicaltrials.gov as NCT00456131. PMID:26354535

Weight loss improves the cardiovascular and metabolic risk associated with obesity. However, insufficient data are available about the health effects of weight gain, separate from the obesity itself. We sought to determine whether the changes in body weight before open gastric bypass surgery (OGB) would have a significant effect on the immediate perioperative hospital course. A retrospective chart review of 100 consecutive patients was performed to examine the effects of co-morbidities and body weight changes in the immediate preoperative period on the hospital length of stay and the rate of admission to the surgical intensive care unit (SICU). Of our class III obese patients undergoing OGB, 95% had ≥1 co-morbid condition and an overall SICU admission rate of 18%. Compared with the patients with no perioperative SICU admission, the patients admitted to the SICU had a greater degree of insulin resistance (homeostatic model analysis-insulin resistance 10.8 ± 1.3 versus 5.9 ± 0.5, P = .001), greater serum triglyceride levels (225 ± 47 versus 143 ± 8 mg/dL, P = .003), and had gained more weight preoperatively (.52 ± .13 versus .06 ± .06 lb/wk, P = .003). The multivariate analyses showed that preoperative weight gain was a risk factor for a longer length of stay and more SICU admissions lasting ≥3 days, as were a diagnosis of sleep apnea and an elevated serum triglyceride concentration. The results of the present retrospective study suggest that weight gain increases the risk of perioperative SICU admission associated with OGB, independent of the body mass index. Sleep apnea and elevated serum triglyceride levels were also important determinants of perioperative morbidity. In view of the increasing epidemic of obesity and the popularity of bariatric surgical procedures, we propose that additional clinical and metabolic research focusing on the understanding of the complex relationship among obesity, positive energy balance, weight gain, and perioperative

Juniperus pollen is highly allergenic and is produced in large quantities across Texas, Oklahoma, and New Mexico. The pollen negatively affects human populations adjacent to the trees, and since it can be transported hundreds of kilometers by the wind, it also affects people who are far from the source. Predicting and tracking long-distance transport of pollen is difficult and complex. One parameter that has been understudied is the hygroscopic weight gain of pollen. It is believed that juniper pollen gains weight as humidity increases which could affect settling rate of pollen and thus affect pollen transport. This study was undertaken to examine how changes in relative humidity affect pollen weight, diameter, and settling rate. Juniperus ashei, Juniperus monosperma, and Juniperus pinchotii pollen were applied to greased microscope slides and placed in incubation chambers under a range of temperature and humidity levels. Pollen on slides were weighed using an analytical balance at 2- and 6-h intervals. The size of the pollen was also measured in order to calculate settling rate using Stokes' Law. All pollen types gained weight as humidity increased. The greatest settling rate increase was exhibited by J. pinchotii which increased by 24 %.

Authors have recently suggested that difficult temperament in infancy may be associated with rapid weight gain, but no previous studies actually report associations between temperament and feeding as a response to infant distress. The purpose of the present study was to examine whether greater infant difficulty elicits more feeding, which in turn leads to more rapid weight gain in early infancy. One hundred fifty-four mother-infant pairs were visited at 3 and 6 months in their homes. Besides anthropometric measures, mothers kept a 24-h diary of their infants' sleep, cry and feed patterns, and answered questions regarding feeding and infant difficultness. The results showed that feeding occurred as a response to nearly half (48%) of the crying intervals recorded, though it more often occurred in the absence of crying (83%). Mothers were most likely to report holding or rocking their infant as the first strategy they would employ if their baby fussed or cried. A regression analysis that included crying, feeding, weaning, sleep and infant weight revealed maternal reports of numbers of feeds per day as the only variable that predicted weight gain from 3 to 6 months. Infant crying is often followed by feeding, and more frequent feeding may promote more rapid weight gain. However, feeding frequency in the first few months appears to be more a matter of maternal discretion than a yoked response to temperamental difficulty. This does not preclude the possibility that overfeeding in later infancy could be tied to temperamental difficulty and subsequently related to overweight in early childhood. © 2012 John Wiley & Sons Ltd.
Full Text Available Introduction: Various factors affect the health of both mother and fetus which maternal nutrition is one of them. Weight gain in pregnancy is one of the valid criteria for assessing nutritional status. The aim of this study was to investigate the relationship between weight gain in pregnancy and birth weight in Yazd city. Methods: This was a cross-sectional study. Data of 200 pregnant women 16 to 40 years that referred to health centers of Yazd were studied.low birth weight and normal weight in infants were considered less than 2500 gr and more than 2500 gr, respectively. Data were analyzed through SPSS 16 software. Results: The Mean age of the study was 26.65 years. Weight gain during pregnancy was 12/39 kg. The mean birth weight was 3147 gr of which 7.5 percent (n = 15 LBW and 92/5 percent (185 patients had normal weight. Mean of BMI was 24.08 kg/m2 in study group. The correlation between maternal weight gain during pregnancy and birth weight was not significant. Conclusion: birth weight may be affected by other factors such as general and mental health of the mother and number of pregnancies, so by identifying these factors more careness than of pregnant women can be taken.

Background: Normal-weight adults gain lower-body fat via adipocyte hyperplasia and upper-body subcutaneous (UBSQ) fat via adipocyte hypertrophy. Objectives: We investigated whether regional fat loss mirrors fat gain and whether the loss of lower-body fat is attributed to decreased adipocyte number or size. Design: We assessed UBSQ, lower-body, and visceral fat gains and losses in response to overfeeding and underfeeding in 23 normal-weight adults (15 men) by using dual-energy X-ray absorptiometry and abdominal computed tomography scans. Participants gained ∼5% of weight in 8 wk and lost ∼80% of gained fat in 8 wk. We measured abdominal subcutaneous and femoral adipocyte sizes and numbers after weight gain and loss. Results: Volunteers gained 3.1 ± 2.1 (mean ± SD) kg body fat with overfeeding and lost 2.4 ± 1.7 kg body fat with underfeeding. Although UBSQ and visceral fat gains were completely reversed after 8 wk of underfeeding, lower-body fat had not yet returned to baseline values. Abdominal and femoral adipocyte sizes, but not numbers, decreased with weight loss. Decreases in abdominal adipocyte size and UBSQ fat mass were correlated (ρ = 0.76, P = 0.001), as were decreases in femoral adipocyte size and lower-body fat (ρ = 0.49, P = 0.05). Conclusions: UBSQ and visceral fat increase and decrease proportionately with a short-term weight gain and loss, whereas a gain of lower-body fat does not relate to the loss of lower-body fat. The loss of lower-body fat is attributed to a reduced fat cell size, but not number, which may result in long-term increases in fat cell numbers. PMID:22760561

Full Text Available Introduction: Gestational weight gain is an important modifiable factor known to influence fetal outcomes including birth weight and adiposity. Leptin is normally correlated with adiposity and is also known to increase throughout pregnancy, as the placenta becomes a source of leptin synthesis. Several studies have reported positive correlations between cord blood leptin level and either birthweight or size for gestational age, as well as body mass index (BMI. Objective: To determine the correlation of prenatal leptin concentration in pregnant adolescents with their gestational weight gain, postpartum weight retention, and weight/length of their newborn. Methods: A cohort study was conducted on pregnant Mexican adolescents from Gestational Week 26–28 to three months postpartum (n = 168 mother–child dyads. An anthropometric assessment was made of each pregnant adolescent, and the serum level of leptin and the intake of energy were determined. The newborn was evaluated each month during postpartum. Clinical records were reviewed to obtain sociodemographic data. Bivariate correlations, tests for repeating measurements and logistic regression models were performed. Results: Leptin concentration gradually increased during the third trimester of pregnancy. At Gestation Week 36, leptin level correlated with gestational weight gain. When comparing adolescents that had the lowest and highest concentration of leptin, the former presented a mean of 6 kg less in gestational weight gain (inter-subject leptin concentration, p = 0.001; inter-subject energy intake, p = 0.497. Leptin concentration and gestational weight gain exerted an effect on the weight of the newborn (inter-subject leptin concentration for Week 32, p = 0.024; inter-subject gestational weight gain, p = 0.011. Newborn length was associated with leptin concentration at Week 28 (leptin effect, p = 0.003; effect of gestational weight gain, p = 0.722. Conclusions: Pregnant adolescents with

The present weight stigma study examined whether attitudes toward and employability of a normal weight person can change after learning that the person had been obese. Participants (N = 154) viewed an image of a normal weight woman and rated their impression of her. Next, participants rated their impression of her overweight image after learning how she had previously gained and subsequently lost weight. Participants rated the model far less favorably including perceived employability if they thought the once overweight model lost weight through surgery vs. diet and exercise. How the model initially gained the weight had little impact on participant ratings. Surgical weight loss had a significant impact on personality judgments. These negative views extended to hiring decisions.

Gestational weight gain (GWG) has in numerous studies been associated with offspring birth weight (BW) and childhood weight. However, these associations might be explained by genetic confounding as offspring inherit their mother's genetic potential to gain weight. Furthermore, little is known about...... whether particular periods of pregnancy could influence offspring body weight differently. We therefore aimed to explore total and trimester-specific effects of GWG in monozygotic (MZ) twin mother-pairs on their offspring's BW, weight at 1 year and body mass index (BMI) at 5 and 10 years. MZ twin mothers...... statistically weak, suggested no associations between GWG and offspring weight or BMI during infancy or childhood. Our study suggests that total, and possibly also second and third trimester, GWG are associated with offspring BW when taking shared genetic and environmental factors within twin pairs into account...

Main outcomes were: body composition, resting metabolic rate, energy intake, energy expenditure, and weight regain at follow-up.Results: All body composition measures significantly decreased after intervention (all P ≤ 0.01 while all measures of fatness increased significantly after the 12-month follow-up (P ≤ 0.01. Body weight gain since menopause was associated with body weight regain (r = 0.65; P = 0.003 after follow-up even after adjustment for confounders.Conclusion: Weight gain since menopause is associated with body weight regain following the weight loss program. Therefore, weight gain since menopause should be considered as a factor influencing weight loss maintenance in older women.Keywords: obesity, body weight, weight regain, postmenopausal women, aging
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.

Excessive gestational weight gain (GWG) is associated with increased birth weight and neonatal adiposity. However, timing of excessive GWG may have a differential impact on birth outcomes. The objective of this study was to compare the effect of early and mid/late excessive GWG on newborn anthropometry in the context of the Canadian clinical recommendations that are specific for first trimester and for second/third trimesters based on maternal pre-pregnancy BMI. We included 607 glucose-tolerant women in our main analyses, after excluding women who had less than the recommended total GWG. Maternal body weight was measured in early pregnancy, mid-pregnancy, and late pregnancy. Maternal and fetal clinical outcomes were collected, including newborn anthropometry. Women were divided into four groups according to the Canadian guidelines for GWG in the first and in the second/third trimesters: (1) "overall non-excessive" (reference group); (2) "early excessive GWG"; (3) "mid/late excessive GWG"; and (4) "overall excessive GWG." Differences in newborn anthropometry were tested across GWG categories. Women had a mean (±SD) pre-pregnancy BMI of 24.7 ± 5.2 kg/m(2) and total GWG of 15.3 ± 4.4 kg. Women with mid/late excessive GWG gave birth to heavier babies (gestational age-adjusted birth weight z-score 0.33 ± 0.91) compared with women in the reference group (0.00 ± 0.77, P = 0.007), whereas women with early excessive GWG gave birth to babies of similar weight (gestational age-adjusted z-score 0.01 ± 0.86) to the reference group (0.00 ± 0.77, P = 0.84). When we stratified our analyses and investigated women who gained within the recommendations for total GWG, mid/late excessive GWG specifically was associated with greater newborn size, similar to our main analyses. Excessive GWG in mid/late pregnancy in women who did not gain weight excessively in early pregnancy is associated with increased birth size, even in those who gained within the Canadian recommendations

The aim of the present study was to examine the influence of a supervised and regular program of aquatic activities throughout gestation on maternal weight gain and birth weight. A randomized clinical trial. Instituto de Obstetricia, Ginecología y Fertilidad Ghisoni (Buenos Aires, Argentina). One hundred eleven pregnant women were analyzed (31.6 ± 3.8 years). All women had uncomplicated and singleton pregnancies; 49 were allocated to the exercise group (EG) and 62 to the control group (CG). The intervention program consisted of 3 weekly sessions of aerobic and resistance aquatic activities from weeks 10 to 12 until weeks 38 to 39 of gestation. Maternal weight gain, birth weight, and other maternal and fetal outcomes were obtained by hospital records. Student unpaired t test and χ(2) test were used; P values ≤.05 indicated statistical significance. Cohen's d was used to determinate the effect size. There was a higher percentage of women with excessive maternal weight gain in the CG (45.2%; n = 28) than in the EG (24.5%; n = 12; odds ratio = 0.39; 95% confidence interval: 0.17-0.89; P = .02). Birth weight and other pregnancy outcomes showed no differences between groups. Three weekly sessions of water activities throughout pregnancy prevents excessive maternal weight gain and preserves birth weight. The clinicaltrial.gov identifier: NCT 02602106.

To evaluate the impact of a worksite intervention to prevent weight gain among adult workers. A controlled community trial was performed by dividing the workers into two groups: intervention group (IG) and control group (CG). The theoretical framework applied was Intervention Mapping Protocol and the intervention was implemented through interactive software for weight self-monitoring. To evaluate the impact of the intervention, the differences in weight, BMI and waist circumference between the IG and CG were assessed before and 6 months after the intervention by regression models. Additionally, the sustainability of the intervention was evaluated at 12 months after the intervention. Settings São Paulo, Brazil. Four companies; 281 workers for the analysis of effectiveness and 427 for the analysis of sustainability. The intervention resulted in significant reductions in weight, BMI and waist circumference in the IG compared with the CG. The impact of the intervention on IG individuals' body weight was -0·73 kg, while the weight of CG individuals increased. IG individuals with adequate initial weights did not show significant variations, while those who were overweight demonstrated a significant reduction in body weight. The intervention resulted in a reduction of 0·26 kg/m2 in BMI and 0·99 cm in waist circumference, and the sustainability analysis after 12 months showed a continued reduction in body weight (-0·72 kg). The behavioural intervention was effective, resulting in weight maintenance among participants with adequate initial weight and in significant reductions among those who were overweight. More research on longer-term weight maintenance is needed.

Full Text Available Poor maternal nutrition is a major contributor to the high incidence of low birth weight deliveries in developing countries. This study aimed to assess the impact of second trimester maternal dietary intake on gestational weight gain and neonatal birth weight. A longitudinal study was conducted in a tertiary care hospital in Sri Lanka. Participants were 141 pregnant women at 18–24 weeks gestation who were followed up until delivery. Maternal dietary intake was assessed using a validated Food Frequency Questionnaire at 21.1 ± 1.8 gestational weeks. Gestational weight gain was examined at the end of 28 weeks gestation and at the end of pregnancy. Energy and nutrient intakes were calculated using NutriSurvey 2007 (EBISpro, Willstaett, Germany nutrient analysis software, modified for Sri Lankan foods. The mean total gestational weight gain of women with low carbohydrate intake (229–429 g/day was 2.2 kg less than that of women with moderate carbohydrate intake (430–629 g/day (95% confidence interval (CI 0.428–4.083 kg; p = 0.016. Similarly, babies of women with low carbohydrate intake were 312 g lighter compared with those of women with a moderate carbohydrate intake (95% CI 91–534 g; p = 0.006. Our results suggest that second trimester maternal carbohydrate intake has significant impacts on total gestational weight gain and neonatal birth weight.

Background: Gestational weight gains (GWGs) that exceed the 2009 Institute of Medicine recommended ranges increase risk of long-term postpartum weight retention; conversely, GWGs within the recommended ranges are more likely to result in positive maternal and fetal outcomes. Despite this evidence, recent epidemiologic studies have shown that the majority of pregnant women gain outside the target GWG ranges. A mathematical model that predicts GWG and energy intake could provide a clinical tool for setting precise goals during early pregnancy and continuous objective feedback throughout pregnancy. Objective: The purpose of this study was to develop and validate a differential equation model for energy balance during pregnancy that predicts GWG that results from changes in energy intakes. Design: A set of prepregnancy BMI–dependent mathematical models that predict GWG were developed by using data from a longitudinal study that measured gestational-changes in fat-free mass, fat mass, total body water, and total energy expenditure in 63 subjects. Results: Mathematical models developed for women with low, normal, and high prepregnancy BMI were shown to fit the original data. In 2 independent studies used for validation, model predictions of fat-free mass, fat mass, and total body water matched actual measurements within 1 kg. Conclusions: Our energy-balance model provides plausible predictions of GWG that results from changes in energy intakes. Because the model was implemented as a Web-based applet, it can be widely used by pregnant women and their health care providers. PMID:22170365

Cross-sectional studies have reported significant temporal increases in prevalence of childhood obesity in both genders and various racial groups, but recently the rise has subsided. Childhood obesity prevention trials suggest that, on average, overweight/obese children lose body weight and nonoverweight children gain weight. This investigation tested the hypothesis that overweight children lose body weight/fat and nonoverweight children gain body weight/fat using a longitudinal research design that did not include an obesity prevention program. The participants were 451 children in 4th to 6th grades at baseline. Height, weight, and body fat were measured at month 0 and month 28. Each child's BMI percentile score was calculated specific for their age, gender and height. Higher BMI percentile scores and percent body fat at baseline were associated with larger decreases in BMI and percent body fat after 28 months. The BMI percentile mean for African-American girls increased whereas BMI percentile means for white boys and girls and African-American boys were stable over the 28-month study period. Estimates of obesity and overweight prevalence were stable because incidence and remission were similar. These findings support the hypothesis that overweight children tend to lose body weight and nonoverweight children tend to gain body weight.

Gestational weight gain (GWG) is an important predictor of short and long-term pregnancy outcomes for both mother and child, and women who set a GWG goal are more likely to gain within recommended ranges. Little information is available regarding potentially modifiable factors that underlie a woman's GWG goals. Our aims were to explore women's perceptions regarding factors that affect GWG, their understanding of appropriate GWG, their goal-setting experiences including patient-health care provider (HCP) conversations, and supportive interventions they would most like to help them achieve the recommended GWG. We conducted nine in-depth interviews and seven focus groups with a total of 33 Boston, Massachusetts (MA) area women who were pregnant and had delivered within the prior 6 months. We recorded and transcribed all interviews. Two investigators independently coded resulting transcripts. We managed data using MAXQDA2 and conducted a content analysis. Perceived factors that contributed to GWG goal-setting included the mother's weight control behaviors concerning exercise and diet-including a "new way of eating for two" and "semblance of control", experiences during prior pregnancies, conversations with HCPs, and influence from various information sources. Women focused on behaviors with consistent messaging across multiple sources of information, but mainly trusted their HCP, valued one-to-one conversations with them about GWG, preferred that the HCP initiate the conversation about GWG goals, and would be open to have the conversation started based on visual aid based on their own GWG progression. Pregnant women highly value discussions with their HCP to set GWG goals. Pregnant women view their clinicians as the most reliable source of information and believe that clinicians should open weight-related discussions throughout pregnancy.
Full Text Available The aim of this study was to analyse the impact of maternal BMI at start of pregnancy and maternal weight gain during pregnancy on the risk of various diseases later in life.In a population-based cohort from southern Sweden, women with at least one delivery registered in the Swedish Medical Birth Register ten or more years before answering a health questionnaire were identified (n = 13,608. Complete data were found in 3,539 women.Women with BMI >25 at start of pregnancy had increased risk of developing obesity (OR 21.9, diabetes (OR 6.4, cardiac disease (OR 2.7, endocrine diseases (OR 2.3, and other morbidity (OR 1.4, compared with women of normal weight. A high weight gain (>15 kg during pregnancy was associated to later risk of overweight (OR 2.0 and obesity (OR 2.2, but not diabetes, cardiac disease, or endocrine diseases. A positive association was found between low weight gain and the risk of developing psychiatric disorders (OR 1.6.A high BMI at start of pregnancy significantly increased the risk of several diseases later in life. However, a high weight gain during pregnancy was only significant for future overweight and obesity. These findings have implications for both pregestational intervention and post gestational follow up of obese and overweight women.

Both the history of obesity and weight loss may change how menopause affects metabolic health. The purpose was to determine whether obesity and/or weight loss status alters energy balance (EB) and subsequent weight gain after the loss of ovarian function. Female lean and obese Wistar rats were randomized to 15% weight loss (WL) or ad libitum fed controls (CON). After the weight loss period, WL rats were kept in EB at the reduced weight for 8 weeks prior to ovariectomy (OVX). After OVX, all rats were allowed to eat ad libitum until weight plateaued. Energy intake (EI), spontaneous physical activity, and total energy expenditure (TEE) were measured with indirect calorimetry before OVX, immediately after OVX, and after weight plateau. Changes in energy intake (EI), TEE, and weight gain immediately after OVX were similar between lean and obese rats. However, obese rats gained more total weight and fat mass than lean rats over the full regain period. Post-OVX, EI increased more (P ≤ 0.03) in WL rats (58.9 ± 3.5 kcal/d) than CON rats (8.5 ± 5.2 kcal/d), and EI partially normalized (change from preOVX: 20.5 ± 4.2 vs. 1.5 ± 4.9 kcal/day) by the end of the study. As a result, WL rats gained weight (week 1:44 ± 20 vs. 7 ± 25 g) more rapidly (mean = 44 ± 20 vs. 7 ± 25 g/week; P < 0.001) than CON Prior obesity did not affect changes in EB or weight regain following OVX, whereas a history of weight loss prior to OVX augmented disruptions in EB after OVX, resulting in more rapid weight regain. © 2017 The Authors.

The aim of the study was to conduct a survey using a dedicated questionnaire to estimate feeding difficulties, gastrointestinal involvement and weight gain in a population of 118 Duchenne muscular dystrophy (DMD) patients (age range 13.80-35.8 years). All the answers were entered in a database and the data analysed subdividing the cohort into age groups (3-9, 9-13, 13-18, 18-24, 24-30, 30-36 years). The results indicate that chewing difficulties are frequent and become increasingly present with age, associated with a progressive increase of the duration of meals. Episodes of choking or other clinical signs of swallowing difficulties are in contrast much less frequent even after age 18. Aspiration pneumonia were also not very frequent and only occurred in 7/118. Clinical signs of gastroesophageal reflux requiring treatment were only found in 5 while 43/118 complained of constipation requiring treatment. Very few of our patients had their weight above 2 SD (n = 4) and this was always found in patients between 9 and 18 years while after this age there was an increasing number of patients with weight below 2 SD. The results of our survey suggest that although choking is one of the most feared complications in patients with DMD, clinical signs of swallowing abnormalities are infrequent when collecting clinical information retrospectively. Further studies using an objective evaluation such as videofluoroscopy are needed to identify minor signs that may not be obvious on clinical examination.

To evaluate the effects of maternal pre-pregnancy body mass index (pre-BMI) and gestational weight gain (GWG) on neonatal birth weight (NBW) in the population of Chinese healthy pregnant women, attempting to guide weight control in pregnancy. A retrospective cohort study of 3772 Chinese women was conducted. The population was stratified by maternal pre-BMI categories as underweight (pre-BMI, GWG, and NBW were investigated by multivariate analysis. NBW increased significantly with the increase of maternal pre-BMI level (P0.05). The multivariate analysis showed that both pre-BMI and GWG were positively correlated with NBW (Ppre-BMI, underweight predicted an increased odds ratio of small-for-gestational-age (SGA) and decreased odds ratio for macrosomia and large-for-gestational-age (LGA), and the results were opposite for overweight. With the increase of GWG, the risk of SGA decreased and the risks of macrosomia and LGA increased. In addition, in different pre-BMI categories, the effects of weight gain in the first trimester on NBW were different (Ppre-BMI and GWG, extreme pre-BMI and GWG are both associated with increased risks of abnormal birth weight, and maternal pre-BMI may modify the effect of weight gain in each trimester on NBW. A valid GWG guideline for Chinese women is an urgent requirement, whereas existing recommendations seem to be not very suitable for the Chinese.

BACKGROUND: Clinical recommendations to limit gestational weight gain (GWG) imply high GWG is causally related to adverse outcomes in mother or offspring, but GWG is the sum of several inter-related complex phenotypes (maternal fat deposition and vascular expansion, placenta, amniotic fluid...... and fetal growth). Understanding the genetic contribution to GWG could help clarify the potential effect of its different components on maternal and offspring health. Here we explore the genetic contribution to total, early and late GWG. PARTICIPANTS AND METHODS: A genome-wide association study was used...... to identify maternal and fetal variants contributing to GWG in up to 10 543 mothers and 16 317 offspring of European origin, with replication in 10 660 mothers and 7561 offspring. Additional analyses determined the proportion of variability in GWG from maternal and fetal common genetic variants...

This study determined how sociocultural messages to change one's body are perceived by adolescents from different cultural groups. In total, 4904 adolescents, including Australian, Chilean, Chinese, Indo-Fijian, Indigenous Fijian, Greek, Malaysian, Chinese Malaysian, Tongans in New Zealand, and Tongans in Tonga, were surveyed about messages from family, peers, and the media to lose weight, gain weight, and increase muscles. Groups were best differentiated by family pressure to gain weight. Girls were more likely to receive the messages from multiple sociocultural sources whereas boys were more likely to receive the messages from the family. Some participants in a cultural group indicated higher, and others lower, levels of these sociocultural messages. These findings highlight the differences in sociocultural messages across cultural groups, but also that adolescents receive contrasting messages within a cultural group. These results demonstrate the difficulty in representing a particular message as being characteristic of each cultural group. Copyright © 2014 Elsevier Ltd. All rights reserved.

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.

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.

The objective of this study was to investigate if food intake (dairy, snacks, caloric beverages, bread, cheese, margarine/butter, potato/rice/pasta/grains, red meat, fish and fruit/berries/vegetables) is associated with gestational weight gain (GWG) in Swedish women. Four day food records from 95 pregnant Swedish women were collected in the last trimester. GWG was calculated as weighed body weight in the last trimester (median gestational week 36) minus self-reported pre-pregnancy body weight. Excessive GWG was defined according to the guidelines by the Institute of Medicine. Food groups tested for association with GWG were dairy (milk, yoghurt and sour milk), snacks (sweets, crisps, popcorn, ice cream and cookies, but not nuts and seeds), caloric beverages (soft drinks, juice, lemonade and non-alcoholic beer), bread, cheese, margarine/butter, potato/rice/pasta/grains, red meat, fish and fruit/berries/vegetables. Median (lower-upper quartiles) GWG was 12.1 kg (10.0-15.3). In total, 28 % had an excessive GWG. Excessive GWG was most common among pre-pregnancy overweight and obese women, where 69 % had an excessive GWG. Median daily intake of fruits and vegetables was 352 g (212-453), caloric beverages was 238 g (100-420) and snacks was 111 g (69-115). Multivariable linear regression analysis showed that intake of caloric beverages, snacks, fish, bread and dairy in the last trimester of pregnancy were positively related to GWG (R(2) = 0.32). Multivariable logistic regression analysis showed that intake of caloric beverages, snacks, fish, and bread was associated with higher odds ratios for excessive GWG. Intake of caloric beverages, snacks, fish and bread were positively related to excessive GWG. Thus, these results indicate that maternal dietary intake should be given higher attention in the antenatal care.

AIMS: Weight gain is an ongoing challenge when initiating insulin therapy in patients with Type 2 diabetes mellitus. However, if prediction of insulin associated weight gain was possible on an individualized level, targeted initiatives could be implemented to reduce weight gain. The objective...... of this study was to identify predictors of weight gain in insulin treated patients with Type 2 diabetes mellitus. METHODS: A total of 412 individuals with Type 2 diabetes mellitus were, in addition to metformin or placebo, randomized into 18-month treatment groups with three different insulin analogue...... treatment regimens. Participants with excessive weight gain were defined as the group with weight gain in the 4(th) quartile. We developed a pattern classification method to predict individuals prone to excessive weight gain. RESULTS: The median weight gain among all patients (n = 412) was 2.4 (95...

We intended to (i) to compare the composition of weight loss and weight gain using densitometry, deuterium dilution (D₂O), dual-energy X-ray absorptiometry (DXA), magnetic resonance imaging (MRI) and the four-compartment (4C) model and (ii) to compare regional changes in fat mass (FM), fat-free mass (FFM) and skeletal muscle as assessed by DXA and MRI. Eighty-three study participants aged between 21 and 58 years with a body mass index range of 20.2-46.8 kg/m(2) had been assessed at two different occasions with a mean follow-up between 23.5 and 43.5 months. Body-weight changes within weight stable, a gain or a loss of >3% of initial weight was considered as a significant weight change. There was a considerable bias between the body-composition data obtained by the individual methods. When compared with the 4C model, mean bias of D₂O and densitometry was explained by the erroneous assumption of a constant hydration of FFM, thus, changes in FM were underestimated by D₂O but overestimated by densitometry. Because hydration does not normalize after weight loss, all two-component models have a systematic error in weight-reduced subjects. The bias between 4C model and DXA was mainly explained by FM% at baseline, whereas FFM hydration contributed to additional 5%. As to the regional changes in body composition, DXA data had a considerable bias and, thus, cannot replace MRI. To assess changes in body composition associated with weight changes, only the 4C model and MRI can be used with confidence.

Background Weight gain during pregnancy has an important impact on maternal and neonatal health. Unlike the Institute of Medicine (IOM) recommendations for weight gain in singleton pregnancies, those for twin gestations are termed “provisional”, as they are based on limited data. The objectives of this study were to determine the neonatal and maternal outcomes associated with gaining weight below, within and above the IOM provisional guidelines on gestational weight gain in twin pregnancies, ...

To assess the impact of a group lifestyle intervention on gestational weight gain in a cohort of obese pregnant women. A cohort study comparing 60 pregnant women enrolled in an educational intervention with controls from the same institution who receive routine prenatal care. Subjects were matched with controls by pre-pregnancy body mass index, parity and ethnicity. Subjects participated in group and individual counseling sessions focused on diet, exercise and weight goals. The primary outcome was gestational weight gain. A greater number of patients in the intervention group met the Institute of Medicine weight gain recommendations (35 versus 24, p = 0.0446). Mean gestational weight gain of participants was lower than the control group, but this was not statistically significant. Number of sessions attended was associated with a decrease in total weight gained. Educational interventions targeting obese pregnant women may be an effective way to limit gestational weight gain. Participation in educational sessions likely influences total weight gain.

Here we explore the genetic contribution to total, early and late GWG. A genome-wide association study was used to identify maternal and fetal variants contributing to GWG in up to 10 543 mothers and 16 317 offspring of European origin, with replication in 10 660 mothers and 7561 offspring. Additional analyses determined the proportion of variability in GWG from maternal and fetal common genetic variants and the overlap of established genome-wide significant variants for phenotypes relevant to GWG (for example, maternal body mass index (BMI) and glucose, birth weight). Approximately 20% of the variability in GWG was tagged by common maternal genetic variants, and the fetal genome made a surprisingly minor contribution to explain variation in GWG. Variants near the pregnancy-specific beta-1 glycoprotein 5 (PSG5) gene reached genome-wide significance (P=1.71 × 10-8) for total GWG in the offspring genome, but did not replicate. Some established variants associated with increased BMI, fasting glucose and type 2 diabetes were associated with lower early, and higher later GWG. Maternal variants related to higher systolic blood pressure were related to lower late GWG. Established maternal and fetal birth weight variants were largely unrelated to GWG. We found a modest contribution of maternal common variants to GWG and some overlap of maternal BMI, glucose and type 2 diabetes variants with GWG. These findings suggest that associations between GWG and later offspring/maternal outcomes may be due to the relationship of maternal

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...
Full Text Available Excessive weight gain, hyperglycemia, type 2 diabetes and hyperlipidemia are significant clinical adverse effects that appear as a result of the treatment with second generation atypical antipsychotic drugs. These drugs possibly cause weight gain by stimulating appetite and increasing insulin resistance. Amantadine, nizatidine, ranitidine, famotidine, topiramate, reboxetine and metformin are notified as the effective drugs which were used in order to prevent the weight gain due to atypical antipsychotic drugs. As an antidiabetic agent, metformin draws attention due to reducing weight gain and correcting insulin resistance. The aim of this paper was to evaluate studies searching fort he effect of metformin on weight-gain due to atypical antipsychotics.

Full Text Available Sustainable production is a principle in which we must meet the needs of the present without compromising the capacity of future generations. Despite the successful development of pesticides against endo and ectoparasites found in domestic ruminants, these parasites are still the major problem of the herbivore production system. The purpose of this study was to know the population of gastrintestinal parasites and their influence on weight gain of calves kept in organic and conventional grazing. Thus, organic and conventional calves were randomly selected in 2008 and 2009. The fecal egg count (FEC indentified the following genders of helminths: Haemonchus, Trichostrongylus, Oesophagostomum, Cooperia, Strongyloides, Trichuris and oocysts of Eimeria. There was no significant difference (p>0.05 between FEC in organic and conventional animals. Calves younger than 6 months showed significant higher infection (p<0.05 than calves between 7 and 12 months of age. The weight gain observed during the study was of 327g/day and 280g/day for conventional and organic systems animals, respectively. Consequently, the combination of sustainable practices of grazing associated with the selective application of anthelmintics may be a feasible alternative for nematode control in a conventional system and in transition to an organic one.

The aims of the study were to assess whether women during the first year of college experience (1) significant weight gain; (2) a prospective relation between dietary restraint and weight gain; (3) an increase in disordered eating; and (4) a prospective relation between dietary restraint or concern about the Freshmen 15 (i.e., weight gain of 15 lbs during the freshman year of college) and disordered eating. Participants were 336 female students in their first year of college who completed questionnaire measures of Body Mass Index (BMI), eating disorder pathology, dietary restraint, body image, and self-esteem. Participants' mean weight gain was approximately 3 lbs (1.5 kg), and among those who gained weight, the mean gain was 7.32 lbs (3.3 kg). Dietary restraint in September did not predict weight change in April, but participants who lost weight reported significantly greater dietary restraint than those participants who gained weight. Eating disorder symptoms increased significantly from September to April. Dietary restraint, concern about the "Freshman 15", and self-esteem in September uniquely predicted EDE-Q Weight and Shape Concern subscale scores in April. Female students in their first year of college gain a small but significant amount of weight, and weight gain was mostly unrelated to dietary restraint. Disordered eating increases during the first year of college and, is predicted by prospective dietary restraint and concerns about weight gain.

Inconsistent findings in previous studies of the association between sleep duration and changes in body mass index (BMI) may be attributed to misclassification of sleep duration fluctuations over time and unmeasured confounders such as genetic factors. The aim of the present study was to overcome these failings by using repeated measurements and panel data analysis to examine the sleep-BMI association. Panel data were derived by secondary use of the data from mandatory health checkups at a Japanese gas company. Male non-shift workers aged 19-39 years in 2007 were annually followed until 2010 (n = 1687, 6748 records). BMI was objectively measured, and sleep duration was self-reported. Compared with 7-hour sleepers, panel analysis with the population-averaged model showed a significant increase in BMI among 5-hour (0.11 kg/m(2), P = 0.001), 6-hour (0.07 kg/m(2), P = 0.038), and ≥8-hour (0.19 kg/m(2), P = 0.009) sleepers. On the other hand, after adjustment for unobserved time-invariant confounders using the fixed-effects model, the magnitude of the association was considerably attenuated and no longer significant (5-hour, 0.07 kg/m(2), P = 0.168; 6-hour, 0.02 kg/m(2), P = 0.631; ≥8-hour sleepers, 0.06 kg/m(2), P = 0.460). The longitudinal association between sleep duration and changes in BMI may be upwardly biased by unobserved time-invariant confounders rather than misclassified sleep duration. The net effect of sleep duration on weight gain may therefore be less than previously believed.

It was recently postulated that a nutritional intervention aiming at achieving weight gain might increase survival in ALS patients. This article discusses the effect of nutritional status and weight gain on survival, respiratory status and physical function. Based on the available literature, it remains unknown whether weight gain during the progression of the disease improves survival whatever the baseline body weight is. A high body mass index may impair respiratory muscle function and pass...
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 ability of clozapine to induce weight gain in female rats was investigated in three studies with progressively lowered doses of clozapine. In an initial preliminary high dose study, clozapine at 6 and 12 mg/kg (i.p., b.i.d.) was found to induce weight loss. In a subsequent intermediate dose study, we obtained no evidence for clozapine-induced weight gain despite using identical procedures and doses of clozapine (1-4 mg/kg, i.p., b.i.d.) with which we have observed olanzapine-induced weight gain, hyperphagia, enhanced adiposity and metabolic changes [Cooper G, Pickavance L, Wilding J, Halford J, Goudie A (2005). A parametric analysis of olanzapine-induced weight gain in female rats. Psychopharmacology; 181: 80-89.]. Instead, clozapine induced weight loss without alteration in food intake and muscle mass or changes in levels of glucose, insulin, leptin and prolactin. However, these intermediate doses of clozapine enhanced visceral adiposity and elevated levels of adiponectin. In a final study, low doses of clozapine (0.25-0.5 mg/kg, i.p, b.i.d.) induced weight loss. These data demonstrate that clozapine-induced weight gain can be much more difficult to observe in female rats than olanzapine-induced weight gain. Moreover, these findings contrast with clinical findings with clozapine, which induces substantial weight gain in humans. Clozapine-induced enhanced adiposity appears to be easier to observe in rats than weight gain. These findings, along with other preclinical studies, suggest that enhanced adiposity can be observed in the absence of antipsychotic-induced weight gain and hyperphagia, possibly reflecting a direct drug effect on adipocyte function independent of drug-induced hyperphagia [e.g. Minet-Ringuet J, Even P, Valet P, Carpene C, Visentin V, Prevot D, Daviaud D, Quignard-Boulange A, Tome D, de Beaurepaire R (2007).

This study sought to determine how dietary patterns, self-esteem, depressive symptoms, and intention to lose weight were associated with body size among adolescent African-American mothers 1 year after delivery and with changes in body size over the next year. Cross-sectional and longitudinal self-reported measures were collected 1 year after delivery. Weight and height were collected 1 and 2 years after delivery. The subjects were 118 low-income, African-American adolescent mothers recruited after the birth of their first child. Multivariate analysis of covariance and multivariate regression analysis were conducted to examine predictors of body size 1 year after delivery and changes in body size over the next year. Analyses were adjusted for maternal age, education, breastfeeding history, and intervention. One year after delivery, 33.0% of mothers were overweight (body mass index [BMI] > or =95th percentile) and 23.7% were at risk for overweight (BMI > or =85th and lose weight, chi(2)=10.8, Plose weight were not related to body size or increase in body size. One year after delivery, overweight among adolescent mothers was common and increased over time. Although nearly half of overweight mothers reported an intention to lose weight, their weight gain did not differ from that of other mothers, suggesting that they lack effective weight-loss behaviors, and may be good candidates for intervention. African-American adolescent mothers have high rates of overweight and snack consumption and may benefit from strategies to identify nutritious, palatable, affordable, and accessible alternatives to high-fat snack food.

(1) To use the available research to estimate the amount of weight gained by college freshman during their first year of college. (2) To identify potential predictors of freshman weight gain. A meta-analysis was conducted in November 2008. The analysis focused on articles published in English scientific journals between 1985 and 2008 available on the MEDLINE, Web of Science, and PsycINFO databases and excluded studies of weight change over periods beyond freshman year. Twenty-four studies met the inclusion criteria. Based on a pooled sample of 3,401 cases, mean weight gain was 3.86 (95% confidence intervals [CI] = 3.81-3.91) lbs. Potential contributors to gain were recent dieting, high baseline weight, and psychological stress. The first year of college is a period of vulnerability for weight problems. Further research is needed to better understand freshman weight gain and devise appropriate prevention strategies based on predictors of gain.

The freshman year of college is a period of heightened risk for weight gain. This study examined measures of restrained eating, disinhibition, and emotional eating as predictors of weight gain during the freshman year. Using Lowe's multi-factorial model of dieting, it also examined three different types of dieting as predictors of weight gain. Sixty-nine females were assessed at three points during the school year. Weight gain during the freshman year averaged 2.1 kg. None of the traditional self-report measures of restraint, disinhibition, or emotional eating were predictive of weight gain. However, both a history of weight loss dieting and weight suppression (discrepancy between highest weight ever and current weight) predicted greater weight gain, and these effects appeared to be largely independent of one another. Individuals who said they were currently dieting to lose weight gained twice as much (5.0 kg) as former dieters (2.5 kg) and three times as much as never dieters (1.6 kg), but the import of this finding was unclear because there was only a small number of current dieters (N = 7). Overall the results indicate that specific subtypes of dieting predicts weight gain during the freshman year better than more global measures of restraint or overeating.

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.

Excessive gestational weight gain is associated with adverse infant, childhood and maternal outcomes and research to develop interventions to address this issue is ongoing. The views of women on gestational weight gain and the resources they would consider helpful in addressing this are however largely unknown. This survey aimed to determine the views of newly pregnant women, living in areas of social disadvantage, on 1) their current body weight and potential gestational weight gain and 2) the resources or interventions they would consider helpful in preventing excessive gestational weight gain. A convenience sample of overweight and obese pregnant women living in Fife, UK, were invited to complete a short anonymised questionnaire at their 12 week booking visit. 428 women, BMI>25 kg/m(2), completed the questionnaire. Fifty-four per cent of respondents were obese (231) and 62% were living in areas of mild to moderate deprivation. Over three-quarters of participants felt dissatisfied with their current weight (81%). The majority of women (60%) expressed some concern about potential weight gain. Thirty-nine percent were unconcerned about weight gain during their pregnancy, including 34 women (19%) who reported having retained weight gained in earlier pregnancies. Amongst those concerned about weight gain advice on physical activity (41%) and access to sports/leisure facilities were favoured resources (36%). Fewer women (12%) felt that group sessions on healthy eating or attending a clinic for individualised advice (14%) would be helpful. "Getting time off work" was the most frequently cited barrier (48%) to uptake of resources other than leaflets. These data suggest a lack of awareness amongst overweight and obese women regarding excessive gestational weight gain. Monitoring of gestational weight gain, and approaches for its management, should be formally integrated into routine antenatal care. Barriers to the uptake of resources to address weight gain are numerous

Aim: To assess the effect of various maternal characteristics in diabetic pregnancies on birthweight (BW) taking into account birthweight of an elderly sibling. Method: We identified all pregnant diabetic women in North Jutland County. Birthweight and certain maternal characteristics including Hb......A1c values after 20th gestational week were collected. Multiple regression models were fitted to assess the effect various predictors of birthweight in both entire cohort (n=501) and in a subset with available weight of sibling (n=139). Sibling weight was calculated as relative to expected weight...... adjusted for age and sex using a Danish reference. E.g. an observed sibling weight of 3800 g with expected BW 3400 g predicts 11.8% extra weight equal to 134 grams (114x11.8) and one extra gestational day predicts an additional weight of 27 grams. Results: The effects in terms of additional grams in BW...

To describe the first-week feeding patterns for breast- vs bottle-fed babies, and their association with sustained breast-feeding and infant weight gain at 6 weeks. A longitudinal cohort study. Feeding diaries were completed by mothers in an urban UK community shortly after birth; follow-up weight and feeding data were collected at routine health checks. Mothers of 923 full-term infants born during the recruiting period agreed to join the study. In all, 502 usable diaries were returned from 54% of the cohort. Breast-fed infants were fed more frequently (2.71 h between feeds) than bottle-fed infants (3.25 h between feeds) and mixed-fed infants (3.14 h between feeds) (Pweight gain at 6 weeks for breast-feeders, but no analysed factors were associated with higher weight gain for bottle-feeders. This large-scale study of first-week feeding patterns sheds light on the important and complicated issues of breast-feeding continuation and infant weight gain, with implications for the feeding advice given to mothers. Supplementary bottle feeds were clearly associated with discontinued breast-feeding at 6 weeks. Over that period, higher weight gain was associated with more frequent feeding for breast-fed infants only. Henry Smith Charity, SPARKS, Child Growth Foundation.

Objectives: To determine the effects of pre-pregnancy body mass index (BMI) and gestational weight gain on maternal and fetal complications, and to examine whether Turkish women achieve the recommended gestational weight gain. We also investigated the relationship between pregnancy weight gain and mode of delivery, with an examination of maternal anthropometry. Methods: A retrospective cross-sectional study was conducted on a population of 986 pregnant women between November 2011 and November 2015 at Atatürk Education and Research Hospital, Ankara, Turkey. Maternal age, BMI, monthly weight gain during pregnancy, infant birth weight, gender, and maternal and fetal adverse outcomes were evaluated. Results: The frequency of maternal complications was positively associated with elevated pre-pregnancy BMI (p0.05). The percentage of women who gained the Institute of Medicine (IOM)-recommended amount of weight was the highest in the underweight BMI group (54.1%) and the lowest in the obese BMI group (24.3%). Pregnancy weight gain exceeded IOM recommendations in the overweight (56.3%) and obese (52.5%) groups. Conclusions: While maternal weight gain during pregnancy affects neonatal body weight, higher pre-pregnancy BMI has an adverse effect on recommended weight gain during pregnancy, with increased maternal complications.

Insufficient sleep is associated with obesity, yet little is known about how repeated nights of insufficient sleep influence energy expenditure and balance. We studied 16 adults in a 14- to 15-d-long inpatient study and quantified effects of 5 d of insufficient sleep, equivalent to a work week, on energy expenditure and energy intake compared with adequate sleep. We found that insufficient sleep increased total daily energy expenditure by ∼5%; however, energy intake—especially at night after dinner—was in excess of energy needed to maintain energy balance. Insufficient sleep led to 0.82 ± 0.47 kg (±SD) weight gain despite changes in hunger and satiety hormones ghrelin and leptin, and peptide YY, which signaled excess energy stores. Insufficient sleep delayed circadian melatonin phase and also led to an earlier circadian phase of wake time. Sex differences showed women, not men, maintained weight during adequate sleep, whereas insufficient sleep reduced dietary restraint and led to weight gain in women. Our findings suggest that increased food intake during insufficient sleep is a physiological adaptation to provide energy needed to sustain additional wakefulness; yet when food is easily accessible, intake surpasses that needed. We also found that transitioning from an insufficient to adequate/recovery sleep schedule decreased energy intake, especially of fats and carbohydrates, and led to −0.03 ± 0.50 kg weight loss. These findings provide evidence that sleep plays a key role in energy metabolism. Importantly, they demonstrate physiological and behavioral mechanisms by which insufficient sleep may contribute to overweight and obesity. PMID:23479616

Weight gain after kidney transplantation affects 50% to 90% of kidney transplant recipients. Factors leading to weight gain in recipients are thought to include a change in lifestyle (eg, dietary intake and physical activity), age, race, sex, and immunosuppressant medications. To examine dietary intake and physical activity of kidney transplant recipients at baseline and 3 and 6 months after transplantation to identify contributing factors to weight gain. Descriptive, correlational study using secondary data from a larger parent study examining genetic and environmental contributors to weight gain after kidney transplantation. Forty-four kidney transplant recipients at a mid-South university hospital-based transplant institute who had dietary intake, physical activity, and clinical data at baseline and 3 and 6 months were included. Dietary intake, physical activity, weight, and body mass index. Mean weight gain increased by 6% from baseline to 6 months. Interestingly, dietary intake did not change significantly from baseline to 6 months. Hours of sleep per day decreased during the same period (P = .02). Dietary intake, physical activity, age, race, sex, and immunosuppression showed no significant relationship to weight gain at 6 months. Little consideration has been given to dietary intake and physical activity of kidney transplant recipients and the effects of these variables on weight gain. Further studies with a larger sample are needed, as weight gain after transplantation is a significant risk factor for diminished long-term outcomes.

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. 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. 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. 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.
Full Text Available Madhubhashinee Dayabandara, Raveen Hanwella, Suhashini Ratnatunga, Sudarshi Seneviratne, Chathurie Suraweera, Varuni A de Silva Department of Psychiatry, Faculty of Medicine, University of Colombo, Colombo, Sri Lanka Abstract: Antipsychotic-induced weight gain is a major management problem for clinicians. It has been shown that weight gain and obesity lead to increased cardiovascular and cerebrovascular morbidity and mortality, reduced quality of life and poor drug compliance. This narrative review discusses the propensity of various antipsychotics to cause weight gain, the pharmacologic and nonpharmacologic interventions available to counteract this effect and its impact on adherence. Most antipsychotics cause weight gain. The risk appears to be highest with olanzapine and clozapine. Weight increases rapidly in the initial period after starting antipsychotics. Patients continue to gain weight in the long term. Children appear to be particularly vulnerable to antipsychotic-induced weight gain. Tailoring antipsychotics according to the needs of the individual and close monitoring of weight and other metabolic parameters are the best preventive strategies at the outset. Switching to an agent with lesser tendency to cause weight gain is an option, but carries the risk of relapse of the illness. Nonpharmacologic interventions of dietary counseling, exercise programs and cognitive and behavioral strategies appear to be equally effective in individual and group therapy formats. Both nonpharmacologic prevention and intervention strategies have shown modest effects on weight. Multiple compounds have been investigated as add-on medications to cause weight loss. Metformin has the best evidence in this respect. Burden of side effects needs to be considered when prescribing weight loss medications. There is no strong evidence to recommend routine prescription of add-on medication for weight reduction. Heterogeneity of study methodologies and other

To evaluate the relationships among excessive gestational weight gain, neonatal adiposity, and adverse obstetric outcomes in women with mild gestational diabetes mellitus. This is a secondary analysis of a multicenter randomized clinical trial of women with mild gestational diabetes mellitus. Based on self-reported prepregnancy body weight, gestational weight gain was categorized as excessive if it was greater than 2009 Institute of Medicine guidelines. Maternal outcomes and neonatal anthropomorphic characteristics were compared between women with excessive weight gain and those without excessive weight gain. Multiple linear and logistic regression analyses were performed to adjust for confounding factors. We studied 841 women who participated in the main trial and had prepregnancy body mass index (BMI) and delivery information available (n=431 treatment group, n=410 no treatment). After adjustment for factors including treatment and prepregnancy BMI, excessive weight gain remained associated with large for gestational age (adjusted odds ratio [OR] 2.94, 95% confidence interval [CI] 1.81-4.93), birth weight greater than 4,000 g (adjusted OR 2.56, 95% CI 1.54-4.40), preeclampsia (adjusted OR 2.96, 95% CI 1.35-7.03), and cesarean delivery for labor arrest (adjusted OR 2.37, 95% CI 1.30-4.44). In addition, excessive weight gain was independently associated with increased total neonatal fat (Pdiabetes mellitus, excessive gestational weight gain was independently associated with both greater birth weight and adiposity.

The current research aims to describe the weight-control strategies and family support for young people reporting sustained weight loss in a large, population-based sample. Data were collected as part of Youth'07, a nationally representative survey of the health and well-being of New Zealand youth. New Zealand secondary schools, 2007. Secondary-school students (n 9107). Among young people who attempted weight loss in the previous year, 51% reported long-term weight loss (lost weight and maintained weight loss for 6 months). Students reporting long-term weight loss were more likely to be male, but did not differ by age, ethnicity, socio-economic deprivation or measured weight status from students who reported temporary/recent weight loss or no weight loss. Students with long-term weight loss also reported healthier weight-control strategies (e.g., exercising, eating fewer fatty foods, eating fewer sweets), high parental support for healthy eating/activity and were less likely to report being teased about their weight by their family and having junk food available at home than students with temporary/recent weight loss or no weight loss. Approximately 50% of young people attempting weight loss reported sustained weight loss. Young people who reported sustained weight loss appeared to have more family support than those who did not achieve this, suggesting the importance for weight-control services and interventions in adolescents of actively engaging the family.

Assessment of the joint and independent relationships of gestational weight gain and prepregnancy body mass index (BMI) on risk of infant mortality was performed. This study used Pennsylvania linked birth-infant death records (2003-2011) from infants without anomalies born to mothers with prepregnancy BMI categorized as underweight (n = 58,973), normal weight (n = 610,118), overweight (n = 296,630), grade 1 obesity (n = 147,608), grade 2 obesity (n = 71,740), and grade 3 obesity (n = 47,277). Multivariable logistic regression models stratified by BMI category were used to estimate dose-response associations between z scores of gestational weight gain and infant death after confounder adjustment. Infant mortality risk was lowest among normal-weight women and increased with rising BMI category. For all BMI groups except for grade 3 obesity, there were U-shaped associations between gestational weight gain and risk of infant death. Weight loss and very low weight gain among women with grades 1 and 2 obesity were associated with high risks of infant mortality. However, even when gestational weight gain in women with obesity was optimized, the predicted risk of infant death remained higher than that of normal-weight women. Interventions aimed at substantially reducing preconception weight among women with obesity and avoiding very low or very high gestational weight gain may reduce risk of infant death. © 2015 The Obesity Society.

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. Methods Phenotypic and genetic analyses were completed on 8340 growing tom turkeys that were measured for feed intake and body weight gain over a four-week period from 16 to 20 weeks of age. Results The heritabilities of RG and RIG were 0.19 ± 0.03 and 0.23 ± 0.03, respectively. Residual body weight gain had moderate genetic correlations with feed intake (−0.41) and body weight gain (0.43). All three linear combinations to form the RIG traits had genetic correlations ranging from −0.62 to −0.52 with feed intake, and slightly weaker, 0.22 to 0.34, with body weight gain. Sorted into three equal groups (low, medium, high) based on RG, the most efficient group (high) gained 0.62 and 1.70 kg more (P feed intake for the high group was less (P efficient) had both the lowest (P feed intake (18.86 vs. 19.57 and 20.41 kg) and the highest (P feed intake between the top ranked birds based on different residual feed efficiency traits may be small when looking at the average individual, however, when extrapolated to the production level, the lower feed intake values could lead to significant savings in feed costs over time.

To systematically examine the relationship between sleep duration and subsequent weight gain in observational longitudinal human studies. Systematic review of twenty longitudinal studies published from 2004-October 31, 2010. While adult studies (n = 13) reported inconsistent results on the relationship between sleep duration and subsequent weight gain, studies with children (n = 7) more consistently reported a positive relationship between short sleep duration and weight gain. While shorter sleep duration consistently predicts subsequent weight gain in children, the relationship is not clear in adults. We discuss possible limitations of the current studies: 1) the diminishing association between short sleep duration on weight gain over time after transition to short sleep, 2) lack of inclusion of appropriate confounding, mediating, and moderating variables (i.e., sleep complaints and sedentary behavior), and 3) measurement issues.

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

Participants completed a validated pregnancy physical activity questionnaire (PPAQ, 3 telephone-validated 24-hr dietary recalls, and wore a pedometer for one week. PPWR was measured 6 weeks after delivery. Results showed that 72% had healthy prepregnancy BMIs. However, 52% consumed >300 kcal/day in excess of their EER, 54% exceeded recommended GWG, and more overweight (93% than normal weight women (38% cited nonrecommended GWG targets. Following delivery, 33% were classified as overweight, and 17% were obese. Multiple logistic regressions revealed that women targeting “recommended weight gain advice” were 3 times more likely to meet total GWG recommendations (OR: 3.2, P<0.05; women who complied with weekly GWG goals minimized PPWR (OR: 4.2, P<0.02. In conclusion, appropriate GWG targets, lower energy intakes, and physical activity should be emphasized in prenatal education programs.

High consumption of sugar-sweetened drinks has been associated with weight gain and obesity in the United States. This trend may also be affecting populations with different eating patterns who increasingly are adopting typical US dietary patterns. We assessed whether the consumption of sweetened drinks and other food items increased the likelihood of weight gain in a Mediterranean population. This was a prospective cohort analysis of 7194 men and women with a mean age of 41 y who were followed-up for a median of 28.5 mo with mailed questionnaires. Dietary exposure was assessed with a previously validated semiquantitative food-frequency questionnaire. During follow-up, we observed that 49.5% of the participants increased their weight (x weight gain: 0.64 kg; 95% CI: 0.55, 0.73 kg). In the participants who had gained > or =3 kg in the 5 y before baseline, the adjusted odds ratio of subsequent weight gain for the fifth quintile compared with the first quintile of sugar-sweetened soft drink consumption was 1.6 (95% CI: 1.2, 2.1; P for trend = 0.02). This association was absent in the participants who had not gained weight in the 5-y period before baseline. The consumption of hamburgers, pizza, and sausages (as a proxy for fast-food consumption) was also independently associated with weight gain (adjusted odds ratio for the fifth compared with the first quintile = 1.2; 95% CI: 1.0, 1.4; P for trend = 0.05). We also found a significant, but weaker, association between weight gain and both red meat and sweetened fruit juice consumption. In a Mediterranean cohort, particularly in the participants who had already gained weight, an increased consumption of sugar-sweetened soft drinks and of hamburgers, pizza, and sausages was associated with a higher risk of additional subsequent weight gain.

Maternal nutritional status of pre pregnancy and gestational weight gain affects the preterm birth. The association between maternal nutritional status of pre pregnancy and preterm birth appears to be complex and varied by studies from different countries, thus this association between the gestational weight gain and preterm birth is more consolidated. The study aims to determine any association between the pre pregnancy maternal nutritional status, gestational weight gain and the preterm birth rate in the Albanian context. In case control study, we analyzed women who have delivered in obstetric institutions in Tirana during the year 2012. Body mass index and gestational weight gain of 150 women who had a preterm delivery were compared with those of 150 matched control women who had a normal delivery regarding the gestation age. The self-reported pre pregnancy weight, height, gestational weight gain, age, education and parity are collected through a structured questioner. The body mass index and gestational weight gain are categorized based on the Institute of Medicine recommendation. The multiple logistic regression is used to measure the association between the nutritional status of pre pregnancy and gestational weight gain and the preterm birth rate. The women which have a underweight status or obese of pre pregnancy are more likely to have a preterm birth compared to the women of a normal pre-pregnancy nutritional status (respectively OR =2.7 and 4.3 p<0.05). Women who do not reach the recommended gestational weight gain are more likely to have a preterm birth compared to the women which reach this weight (OR=1.8 p< 0.05). Maternal nutritional status and gestational weight gain affects the risk for preterm birth. Pre-pregnancy and gestation nutritional assessments should be part of routine prenatal visits.

Our aim was to investigate the prevalence and magnitude of weight gain in-patients with bipolar disorder when treated with a second-generation antipsychotic as an add-on treatment to a mood stabilizer in routine clinical practice. Data were derived from the quality register for bipolar disorder in Sweden (BipoläR). Patients with bipolar disorder who started add-on treatment with a SGA (n = 575) were compared at next yearly follow-up with age and sex matched patients who were only treated with a mood stabilizer (n = 566). The primary outcome measure was change in body weight and body mass index (BMI). We also assessed the prevalence of clinically significant weight gain defined as ≥7% gain in body weight. The group that received add-on treatment with antipsychotics neither gained more weight nor were at higher risk for a clinically significant weight gain than the reference group. Instead, factors associated with clinically significant weight gain were female sex, young age, low-baseline BMI, and occurrence of manic/hypomanic episodes. We found no evidence of an overall increased risk of weight gain for patients with bipolar disorder after receiving add-on SGA to a mood stabilizer in a routine clinical setting. © 2017 John Wiley & Sons A/S.

Weight gain during pregnancy has an important impact on maternal and neonatal health. Unlike the Institute of Medicine (IOM) recommendations for weight gain in singleton pregnancies, those for twin gestations are termed "provisional", as they are based on limited data. The objectives of this study were to determine the neonatal and maternal outcomes associated with gaining weight below, within and above the IOM provisional guidelines on gestational weight gain in twin pregnancies, and additionally, to explore ranges of gestational weight gain among women who delivered twins at the recommended gestational age and birth weight, and those who did not. A retrospective cohort study of women who gave birth to twins at ≥20 weeks gestation, with a birth weight ≥ 500 g was conducted in Nova Scotia, Canada (2003-2014). Our primary outcome of interest was small for gestational age (<10th percentile). In order to account for gestational age at delivery, weekly rates of 2nd and 3rd trimester weight gain were used to categorize women as gaining below, within, or above guidelines. We performed traditional regression analyses for maternal outcomes, and to account for the correlated nature of the neonatal outcomes in twins, we used generalized estimating equations (GEE). A total of 1482 twins and 741 mothers were included, of whom 27%, 43%, and 30% gained below, within, and above guidelines, respectively. The incidence of small for gestational age in these three groups was 30%, 21%, and 20%, respectively, and relative to gaining within guidelines, the adjusted odds ratios were 1.44 (95% CI 1.01-2.06) for gaining below and 0.92 (95% CI 0.62-1.36) for gaining above. The gestational weight gain in women who delivered twins at 37-42 weeks with average birth weight ≥ 2500 g and those who delivered twins outside of the recommend ranges were comparable to each other and the IOM recommendations. While gestational weight gain below guidelines for twins was associated with some

Full Text Available Background. Weight gain is frequently reported after hemithyroidectomy but the significance is recently discussed. Therefore, the aim of the study was to examine changes in body weight of hemithyroidectomized patients and to evaluate if TSH increase within the reference range could be related to weight gain. Methods. In a controlled follow-up study, two years after hemithyroidectomy for benign euthyroid goiter, postoperative TSH and body weight of 28 patients were compared to preoperative values and further compared to the results in 47 matched control persons, after a comparable follow-up period. Results. Two years after hemithyroidectomy, median serum TSH was increased over preoperative levels (1.23 versus 2.08 mIU/L, P<0.01 and patients had gained weight (75.0 versus 77.3 kg, P=0.02. Matched healthy controls had unchanged median serum TSH (1.70 versus 1.60 mIU/L, P=0.13 and weight (69.3 versus 69.3 kg, P=0.71. Patients on thyroxin treatment did not gain weight. TSH increase was significantly correlated with weight gain (r=0.43, P<0.01. Conclusion. Two years after hemithyroidectomy for benign euthyroid goiter, thyroid function is lowered within the laboratory reference range. Weight gain of patients who are biochemically euthyroid after hemithyroidectomy may be a clinical manifestation of a permanently decreased metabolic rate.

Full Text Available 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.
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.

Both obesity and gestational diabetes mellitus are increasing in prevalence, being a major health problem in pregnancy with independent and additive impact on obstetrics outcomes. It is recognized that inadequate gestational weight gain is an independent risk factor for pregnancy-related morbidity. The aim of this study was to evaluate the effect of gestational weight gain on obstetric and neonatal outcomes in obese women with gestational diabetes. Retrospective multicenter study of obese women with gestational diabetes. The assessed group was divided into three categories: women who gained below (9 kg) the 2009 Institute of Medicine recommendations. Maternal and neonatal outcomes were compared and adjusted odds ratios calculated controlling for confounders. Only 35,1 % of obese women with gestational diabetes (n = 634) achieved the recommended gestational weight gain; 27,8 % (n = 502) gained below and 37,1 % (n = 670) above the recommendations. There was a positive correlation between gestational weight gain and neonatal birthweight (r = 0,225; p obstetric and neonatal outcomes than an excessive or even an adequate weight gain. Therefore, specific recommendations should be created since gestational weight gain could be a modifiable risk factor for adverse obstetric outcomes.

Since the gut microbiota may play a causal role in the development of obesity, it is important to understand how pre-pregnancy weight and gestational weight gain (GWG) impact the gut microbiota of mothers at the time of delivery and their infants in early life. In this study, we performed 16S rRNA gene sequencing on gut microbiota samples from 169 women 4 days after delivery and from the 844 samples of their infants at six timepoints during the first 2 years of life. We categorized the women (1) according to pre-pregnancy body mass index into overweight/obese (OW/OB, BMI ≥ 25) or non-overweight/obese (BMI diversity and taxonomic composition of the maternal and infant samples by exposure groups. We also compared taxonomic similarity between maternal and infant gut microbiota. Maternal OW/OB was associated with lower maternal alpha diversity. Maternal pre-pregnancy OW/OB and excessive GWG were associated with taxonomic differences in the maternal gut microbiota, including taxa from the highly heritable family Christensenellaceae, the genera Lachnospira, Parabacteroides, Bifidobacterium, and Blautia. These maternal characteristics were not associated with overall differences in the infant gut microbiota over the first 2 years of life. However, the presence of specific OTUs in maternal gut microbiota at the time of delivery did significantly increase the odds of presence in the infant gut at age 4-10 days for many taxa, and these included some lean-associated taxa. Our results show differences in maternal gut microbiota composition at the time of delivery by pre-pregnancy weight and GWG, but these changes were only associated with limited compositional differences in the early life gut microbiota of their infants. Further work is needed to determine the degree to which these maternal microbiota differences at time of birth with OW/OB and GWG may affect the
Full Text Available Olanzapine is a first line medication for the treatment of schizophrenia, but it is also one of the atypical antipsychotics carrying the highest risk of weight gain. Metformin was reported to produce significant attenuation of antipsychotic-induced weight gain in patients, while the study of preventing olanzapine-induced weight gain in an animal model is absent. Berberine, an herbal alkaloid, was shown in our previous studies to prevent fat accumulation in vitro and in vivo. Utilizing a well-replicated rat model of olanzapine-induced weight gain, here we demonstrated that two weeks of metformin or berberine treatment significantly prevented the olanzapine-induced weight gain and white fat accumulation. Neither metformin nor berberine treatment demonstrated a significant inhibition of olanzapine-increased food intake. But interestingly, a significant loss of brown adipose tissue caused by olanzapine treatment was prevented by the addition of metformin or berberine. Our gene expression analysis also demonstrated that the weight gain prevention efficacy of metformin or berberine treatment was associated with changes in the expression of multiple key genes controlling energy expenditure. This study not only demonstrates a significant preventive efficacy of metformin and berberine treatment on olanzapine-induced weight gain in rats, but also suggests a potential mechanism of action for preventing olanzapine-reduced energy expenditure.

Although previous studies showed the long-term effects of sleep duration on risk of weight gain, Western tends to gain weight irrespective of sleep duration over a long period. Conversely, it is showed that body mass index (BMI) decreases during a long period in Japanese and thus, the long-term effect of sleep duration on weight gain and obesity is still unclear in Asia. We followed up 13,629 participants aged 40-79years and prospectively collected data from 1995 to 2006. We divided the participants into five groups according to their self-reported sleep duration: ⩽5h (short sleep), 6h, 7h (reference), 8h, and ⩾9h (long sleep). The main outcome was ⩾5kg weight gain or BMI⩾25kg/m(2) (obesity). We used logistic regression analyses to derive odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for several confounding factors. We observed no association between sleep duration and risk of ⩾5kg weight gain and obesity. After stratification by BMI, long sleepers had a significantly increased risk of ⩾5kg weight gain (OR: 1.36, 95%CI: 1.09-1.70) in obese participants. Among community-dwelling Japanese, only obese long sleepers have a significantly increased long-term risk of ⩾5kg weight gain. Copyright © 2012 Elsevier B.V. All rights reserved.

Prevention of obesity and weight maintenance have become important public health issues. One strategy for prevention of obesity is to identify critical periods of weight gain across the life span. The purpose of this initial evaluation was to determine whether the transition from high school to college is such a critical period. A total of 135 college students were weighed in September and December of their freshman year and a subset also provided data in May. Results showed that statistically significant but modest weight increases occurred during the freshman year for most participants. However, one quarter of participants gained at least 2.3 kg during the first semester of college, and the proportion of participants classified as overweight or obese increased markedly. For this subset of participants, the freshman year of college could be considered a critical period for weight gain. Identifying critical periods for weight gain may be an important first step towards the development of effective obesity prevention programs.
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

Among the proteins secreted by adipocytes, acylation stimulating protein (ASP), which plays a crucial role in energetic balance regulation, merits particular attention. ASP is a protein of the C3 complement system, responsible for glucose and lipids metabolism in an insulin-independent mechanism. ASP's role during pregnancy and its interactions with pregnancy hormones remains unknown. The lipogenic character of ASP may impose a question as to what extent this hormone participates in pregnant women lipogenesis, and what is the basal and postprandial ASP secretion during the second trimester of pregnancy. The results of the examinations of 26 pregnant women during the second trimester of their first pregnancy were analyzed. Due to the limited data available in the literature, a control group was examined. The group consisted of 8 healthy non-pregnant patients within similar age ranges. Blood samples were collected in order to determine ASP, total cholesterol, HDL, LDL and triglyceride levels. Basal ASP levels present in obese pregnant women (group OBP; 30.20 +/- 2.13 ng/mL) were significantly higher than those in the healthy control group (group LnP; 20.49 +/- 1.97 ng/mL), P<0.05. Mann-Whitney U test- analysis of these group differences indicated that OBP patients had significantly higher ASP levels than controls at 30 (P<0.01), 60 (P<0.01), and 120 (P<0.01) min after a meal. After a meal, the incremental ASP area under the curve in group OBW patients was significantly higher from that observed in control group LnP (718,9 +/- 263,9 ng/mL x 2h vs. 35,1 +/- 14,6 ng/mL x 2h, P<0.05). Basal concentration of triglycerides, total cholesterol and LDL cholesterol were significantly higher in all pregnant women compared to the group of non-obese non-pregnant women. It was found that lipid parameters were highly dependent upon body mass gain during pregnancy. Group OBP demonstrated significantly higher basal concentrations of all parameters of lipid metabolism in comparison

To assess the prevalence of weight gain among male and female college freshmen. Study 1 examined weight change over freshman and sophomore years among 904 students attending a state university in Indiana, from 2002-2004. Study 2 examined weight and BMI change over the freshman year among 382 students attending a private university in Rhode Island, from 2004-2006. 77% of Study 1 participants and 70% of Study 2 participants gained weight during their freshman year, largely during the first semester. In Study 1, weight gain averaged 3.5 kg in females and males; in Study 2, weight gain averaged 1.6 kg for females and 2.5 kg for males. Students continued to gain weight their sophomore year, with females 4.2 kg and males 4.3 kg heavier than at start of college. Overweight/obesity rates increased from baseline to end of freshman year for Study 1 (21.6% to 36%) and Study 2 participants (14.7% to 17.8%). The first years of college may be a critical developmental window for establishing weight gain prevention efforts.

To ascertain the relationship between maternal weight gain and birth weight, in every pre-gestational body mass index (BMI) category. A two-stage sampling observational and descriptive study was carried out in the health department of La Ribera (Valencia, Spain). The sample was divided into four groups according to pre-gestational BMI. 140 pregnant women were studied. We observed rising pre-gestational weight gain (PWG) and trimestral gradients. There was a higher increase from the first to the second trimester than from the second to the third trimester in every pre-gestational BMI category. According to the international recommendations of Institute of Medicine, 16.4% of women had an inferior gestational weight gain (GWG), 38.6% were within the recommendations and 45% were above them. The pre-gestational BMI, categorized by the WHO, is related to the birth weight, showing a statistical significance (F=6.636 and and pweight gain than the recommended have newborns with higher birth weight (4,353 ± 821.924 g) and, underweight mothers with a lower weight gain than the recommended, have newborns with lower birth weights (2,900 ± 381.83 g) than the rest of the groups. The absolute gestational weight gain did not show a statistical significance compared to the birthweight in any of the pre-gestational BMI categories and, as an isolated indicator, is not an added value to the prenatal quality control.

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.

Decades of research have reported only weak associations between the intakes of specific foods or drinks and weight gain and obesity. Randomized controlled dietary intervention trials have only shown very modest effects of changes in nutrient intake and diet composition on body weight in obese...... subjects. This review summarizes the scientific evidence on the role mental stress (either in or not in association with impaired sleep) may play in poor sleep, enhanced appetite, cravings and decreased motivation for physical activity. All these factors contribute to weight gain and obesity, possibly via...

Full Text Available Risk factors for obesity and weight gain are typically evaluated individually while "adjusting for" the influence of other confounding factors, and few studies, if any, have created risk profiles by clustering risk factors. We identified subgroups of postmenopausal women homogeneous in their clustered modifiable and non-modifiable risk factors for gaining ≥ 3% weight.This study included 612 postmenopausal women 50-79 years old, enrolled in an ancillary study of the Women's Health Initiative Observational Study between February 1995 and July 1998. Classification and regression tree and stepwise regression models were built and compared.Of 27 selected variables, the factors significantly related to ≥ 3% weight gain were weight change in the past 2 years, age at menopause, dietary fiber, fat, alcohol intake, and smoking. In women younger than 65 years, less than 4 kg weight change in the past 2 years sufficiently reduced risk of ≥ 3% weight gain. Different combinations of risk factors related to weight gain were reported for subgroups of women: women 65 years or older (essential factor: < 9.8 g/day dietary factor, African Americans (essential factor: currently smoking, and white women (essential factor: ≥ 5 kg weight change for the past 2 years.Our findings suggest specific characteristics for particular subgroups of postmenopausal women that may be useful for identifying those at risk for weight gain. The study results may be useful for targeting efforts to promote strategies to reduce the risk of obesity and weight gain in subgroups of postmenopausal women and maximize the effect of weight control by decreasing obesity-relevant adverse health outcomes.

Full Text Available We have investigated the prospective association between excess gestational weight gain (GWG and development of diabetes by 21 years post-partum using a community-based large prospective cohort study in Brisbane, Australia. There were 3386 mothers for whom complete data were available on GWG, pre-pregnancy BMI and self-reported diabetes 21 years post-partum. We used The Institute of Medicine (IOM definition to categorize GWG as inadequate, adequate and excessive. We found 839 (25.78% mothers gained inadequate weight, 1,353 (39.96% had adequate weight gain and 1,194 (35.26% had gained excessive weight during pregnancy. At 21 years post-partum, 8.40% of mothers self-reported a diagnosis of diabetes made by their doctor. In the age adjusted model, we found mothers who gained excess weight during pregnancy were 1.47 (1.11,1.94 times more likely to experience diabetes at 21 years post-partum compared to the mothers who gained adequate weight. This association was not explained by the potential confounders including maternal age, parity, education, race, smoking, TV watching and exercise. However, this association was mediated by the current BMI. There was no association for the women who had normal BMI before pregnancy and gained excess weight during pregnancy. The findings of this study suggest that women who gain excess weight during pregnancy are at greater risk of being diagnosed with diabetes in later life. This relationship is likely mediated through the pathway of post-partum weight-retention and obesity. This study adds evidence to the argument that excessive GWG during pregnancy for overweight mothers has long term maternal health implications.

The purpose of this review was to examine the relationship between exercise dose and reductions in weight gain during pregnancy in exercise interventions. Systematic literature review. Four electronic research databases (PubMed, Web of Science, CINAHL, and Academic Search Premiere) were used to identify exercise interventions conducted with pregnant women. Eligible articles must have satisfied the following criteria: inclusion of a control condition, exercise as a major intervention component, weight gain measured and reported for each experimental condition, description of exercise dose (frequency, intensity and duration), and utilized an adequate number of control conditions to assess independent effects of exercise on weight gain. The literature search identified 4837 articles. Of these, 174 abstracts were screened and 21 intervention studies (18 exercise-only, 3 exercise/diet) were eligible for review. Only 38% of the interventions achieved statistically significant reductions in gestational weight gain. Successful interventions possessed higher adherence and lower attrition rates and were predominantly conducted among normal weight populations. No clear patterns or consistencies of exercise dose and reductions in weight gain were evident. An exercise dose associated with reductions in weight gain was unquantifiable among these interventions. Adherence and retention rates were strong contributors to the success of exercise interventions on gestational weight gain. It is strongly suggested that future researchers investigate methods to increase adherence and compliance, especially among overweight and obese women, and utilize objective measurement tools to accurately evaluate exercise dose performed by the participants and the impact on body composition and weight gain.

Carnitine transfer across the placenta occurs predominantly during the third trimester. Unless L-carnitine is provided, very preterm infants develop carnitine deficiency. Although breast milk and infant formulas contain L-carnitine, parenteral nutrition solutions do not routinely provide L-carnitine. We hypothesized that prolonged L-carnitine supplementation in very preterm infants would improve weight gain and shorten length of stay in the hospital. The study was a double-blind parallel placebo-controlled randomized clinical trial. Eligible patients were power to detect a 10% increase in weight gain from birth until 36 weeks of postmenstrual age or discharge from the hospital. Secondary outcome variables included food efficiency (defined as weight gain divided by caloric intake), weight gain at 4 weeks of age, time to regain birth weight and length of stay. Among the 63 infants enrolled in the trial, 32 were randomized to L-carnitine and 31 to placebo. L-Carnitine supplementation did not significantly affect average daily weight gain from birth until 36 weeks or hospital discharge, or any of the secondary outcome variables. Prolonged supplementation of L-carnitine did not improve long-term weight gain in very preterm infants.

To better understand the mechanisms behind breastfeeding and childhood obesity, we assessed the association of weight gain with the mode of milk delivery aside from the type of milk given to infants. A longitudinal study of infants followed up from birth to age 1 year. Multilevel analyses were conducted to estimate infant weight gain by type of milk and feeding mode. Pregnant women were recruited from a consumer mail panel throughout the United States between May 2005 and June 2007. One thousand eight hundred ninety nine infants with at least 3 weight measurements reported during the first year. Six mutually exclusive feeding categories and proportions of milk feedings given as breastmilk or by bottle. Weight measurements reported on 3-, 5-, 7-, and 12-month surveys. Compared with infants fed at the breast, infants fed only by bottle gained 71 or 89 g more per month when fed nonhuman milk only (P feedings, but it was positively associated with proportion of bottle-feedings among those who received mostly breastmilk. Among infants fed only breastmilk, monthly weight gain increased from 729 g when few feedings were by bottle to 780 g when most feedings were by bottle. Infant weight gain might be associated not only with type of milk consumed but also with mode of milk delivery. Regardless of milk type in the bottle, bottle-feeding might be distinct from feeding at the breast in its effect on infants' weight gain.

Gestational weight gain above or below the 2009 National Academy of Medicine guidelines has been associated with adverse maternal and neonatal outcomes. Although it has been well established that excess gestational weight gain is associated with the development of gestational hypertension and preeclampsia, the relationship between gestational weight gain and adverse perinatal outcomes among women with pregestational (chronic) hypertension is less clear. The objective of this study was to examine the relationship between gestational weight gain above and below National Academy of Medicine guidelines and perinatal outcomes in a large, population-based cohort of women with chronic hypertension. This is a population-based retrospective cohort study of women with chronic hypertension who had term, singleton, vertex births in the United States from 2012 through 2014. Prepregnancy body mass index was calculated using self-reported prepregnancy weight and height. Women were categorized into 4 groups based on gestational weight gain and prepregnancy body mass index: (1) weight gain less than, (2) weight gain within, (3) weight gain 1-19 lb in excess of, and (4) weight gain ≥20 lb in excess of the National Academy of Medicine guidelines. The χ(2) tests and multivariable logistic regression analysis were used for statistical comparisons. Stratified analyses by body mass index category were additionally performed. In this large birth cohort, 101,259 women met criteria for inclusion. Compared to hypertensive women who had gestational weight gain within guidelines, hypertensive women with weight gain ≥20 lb over National Academy of Medicine guidelines were more likely to have eclampsia (adjusted odds ratio, 1.93; 95% confidence interval, 1.54-2.42) and cesarean delivery (adjusted odds ratio, 1.60; 95% confidence interval, 1.50-1.70). Excess weight gain ≥20 lb over National Academy of Medicine guidelines was also associated with increased odds of 5-minute Apgar confidence
Full Text Available Abstract Background Previous research indicated that women are more vulnerable than men to adverse psychological consequences of weight gain. Other research has suggested that weight gain experienced during antipsychotic therapy may also psychologically impact women more negatively. This study assessed the impact of acute treatment-emergent weight gain on clinical and functional outcomes of patients with schizophrenia by patient gender and antipsychotic treatment (olanzapine or haloperidol. Methods Data were drawn from the acute phase (first 6-weeks of a double-blind randomized clinical trial of olanzapine versus haloperidol in the treatment of 1296 men and 700 women with schizophrenia-spectrum disorders. The associations between weight change and change in core schizophrenia symptoms, depressive symptoms, and functional status were examined post-hoc for men and women and for each medication group. Core schizophrenia symptoms (positive and negative were measured with the Brief Psychiatric Rating Scale (BPRS, depressive symptoms with the BPRS Anxiety/Depression Scale and the Montgomery-Asberg Depression Rating Scale, and functional status with the mental and physical component scores on the Medical Outcome Survey-Short Form 36. Statistical analysis included methods that controlled for treatment duration. Results Weight gain during 6-week treatment with olanzapine and haloperidol was significantly associated with improvements in core schizophrenia symptoms, depressive symptoms, mental functioning, and physical functioning for men and women alike. The conditional probability of clinical response (20% reduction in core schizophrenia symptom, given a clinically significant weight gain (at least 7% of baseline weight, showed that about half of the patients who lost weight responded to treatment, whereas three-quarters of the patients who had a clinically significant weight gain responded to treatment.

To examine the associations of TV viewing time and domain-specific physical activity with weight change; to determine whether domain-specific physical activity moderates the potential association of TV viewing time with weight change. We used four-year longitudinal data (baseline: 2003-2004, follow-up: 2007-2008) on 969 adults from selected neighborhoods in Adelaide, Australia (Age: 48.6 ± 10.6 years, 61% females). Mixed models examined four-year weight change as the dependent variable, with TV viewing time, habitual transport and past week domain-specific physical activity at baseline as independent variables. On average, participants gained 1.6 kg over four years. TV viewing time at baseline was positively associated with weight gain at follow-up. Each additional hour of TV viewing was associated with 0.24-0.27 kg of extra weight gain. This relationship was not moderated by recent recall of transport, leisure-time, and occupational physical activity, but was moderated by habitual transport: an additional hour of TV viewing time at baseline was significantly associated with an extra weight gain of 0.65 kg at follow-up among those who were inactive in everyday transport; TV time was not significantly associated with weight change among those who were regularly active in transport. Habitual active transport may protect adults against risk of weight gain associated with prolonged TV viewing time. Copyright © 2012 Elsevier Inc. All rights reserved.

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.

Weight gain has been reported in patients with Parkinson's disease (PD) treated with deep brain stimulation of the subthalamic nucleus (STN-DBS). To evaluate the influence of STN-DBS on weight changes, we studied food-related hormones. Anthropometric parameters and food-related hormones (leptin, adiponectin, resistin, ghrelin, cortisol, insulin, and thyroid stimulating hormone) were measured in 27 patients with STN-DBS during a 12 month period following electrode implantation. Besides marked motor improvements on STN-DBS, PD patients significantly gained weight. The mean weight gain at 12 months was 5.2±(SD)5.8 kg. A significant decrease in cortisol levels compared to baseline appeared at month 2 and persisted at 12 months (pweight gain in PD patients. Direct effects of STN-DBS on hypothalamic catabolic/anabolic peptide balance remain hypothetical and necessitate further elucidation.

College freshmen are highly vulnerable to experiencing weight gain, and this phenomenon is associated with an increased risk of chronic diseases and mortality in older adulthood. Technology offers an attractive and scalable way to deliver behavioral weight gain prevention interventions for this population. Weight gain prevention programs that harness the appeal and widespread reach of Web-based technologies (electronic health or eHealth) are increasingly being evaluated in college students. Yet, few of these interventions are informed by college students' perspectives on weight gain prevention and related lifestyle behaviors. The objective of this study was to assess college freshmen students' concern about weight gain and associated topics, as well as their interest in and delivery medium preferences for eHealth programs focused on these topics. Web-based surveys that addressed college freshmen students' (convenience sample of N=50) perspectives on weight gain prevention were administered at the beginning and end of the fall 2015 semester as part of a longitudinal investigation of health-related issues and experiences in first semester college freshmen. Data on weight gain prevention-related concerns and corresponding interest in eHealth programs targeting topics of potential concern, as well as preferred program delivery medium and current technology use were gathered and analyzed using descriptive statistics. A considerable proportion of the freshmen sample expressed concern about weight gain (74%, 37/50) and both traditional (healthy diet: 86%, 43/50; physical activity: 64%, 32/50) and less frequently addressed (stress: 82%, 41/50; sleep: 74%, 37/50; anxiety and depression: 60%, 30/50) associated topics within the context of behavioral weight gain prevention. The proportion of students who reported interest in eHealth promotion programs targeting these topics was also generally high (ranging from 52% [26/50] for stress management to 70% [35/50] for eating a

Excessive weight gain during pregnancy can have adverse health outcomes for mother and infant throughout pregnancy. However, few studies have identified the psychosocial factors that contribute to women gaining excessive weight during pregnancy. To review the existing literature that explores the impact of psychosocial risk factors (psychological distress, body image dissatisfaction, social support, self-efficacy and self-esteem) on excessive gestational weight gain. A systematic review of peer-reviewed English articles using Academic Search Complete, Cumulative Index to Nursing and Allied Health Literature, MEDLINE Complete, PsycINFO, Informit, Web of Science, and Scopus was conducted. Quantitative studies that investigated psychosocial factors of excessive GWG, published between 2000 and 2014 were included. Studies investigating mothers with a low risk of mental health issues and normally-developing foetuses were eligible for inclusion. From the total of 474 articles located, 12 articles were identified as relevant and were subsequently reviewed in full. Significant associations were found between depression, body image dissatisfaction, and social support with excessive gestational weight gain. No significant relationships were reported between anxiety, stress, self-efficacy, or self-esteem and excessive gestational weight gain. The relationship between psychosocial factors and weight gain in pregnancy is complex; however depression, body dissatisfaction and social support appear to have a direct relationship with excessive gestational weight gain. Further research is needed to identify how screening for, and responding to, psychosocial risk factors for excessive gestational weight gain can be successfully incorporated into current antenatal care.

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

Decades of research have reported only weak associations between the intakes of specific foods or drinks and weight gain and obesity. Randomized controlled dietary intervention trials have only shown very modest effects of changes in nutrient intake and diet composition on body weight in obese subjects. This review summarizes the scientific evidence on the role mental stress (either in or not in association with impaired sleep) may play in poor sleep, enhanced appetite, cravings and decreased motivation for physical activity. All these factors contribute to weight gain and obesity, possibly via decreasing the efficacy of weight loss interventions. We also review evidence for the role that lifestyle and stress management may play in achieving weight loss in stress-vulnerable individuals with overweight. © 2017 World Obesity Federation.

The objective of this study was to quantify the weight gain of freshmen during their first 12 weeks at Cornell University. In addition, students completed questionnaires that revealed particular behaviors and activities that were associated with weight gain. Serial, correlational study. A total of 68 freshmen from Cornell University. A total of 60 students were weighed during the first week of the semester, then again 12 weeks later. They were also given a questionnaire to complete concerning their behavior during the previous 12 weeks. After adjusting for clothing weights, the mean weight gain of the freshmen was 1.9+/-2.4 kg, a value significantly different from 0. Two regression models generated from the questionnaire were fitted to the weight gain. The first linear regression model (Model 1) accounted for 58% of the variance and indicated that eating in the 'all-you-can-eat' dining halls accounted for 20% of the variance in weight gain. Snacking and eating high-fat 'junk food' accounted for anther 20%. When initial weight was used as a covariate (Model 2), the consumption of junk foods, meal frequency and number of snacks accounted for 47% of the variance. The study clearly demonstrated that significant weight gain during first semester college is a real phenomenon and can be attributed to tangible environmental stimuli. The weight gain is considerably greater than that observed in the population and may be useful as a model to test various techniques that may reduce or reverse the 'epidemic' of obesity observed in the general population.

Atypical antipsychotics appear to have the greatest potential to induce weight gain. Antipsychotic-induced weight gain is the one of main cause of non-compliance and discontinuation of treatment, often resulting in the relapse of psychosis. To compare the weight gain between amisulpride and blonanserin treatment, in persons with psychosis. Fifty six subjects with psychosis attending psychiatry department at KR Hospital, Mysore were randomized into two equal groups. After obtaining informed consent, subjects of group I received amisulpride tablets 200 mg BD, and group II received blonanserin tablets 4 mg BD, for eight weeks. Body weight, Body Mass Index (BMI) and Waist Hip Ratio (WHR) were measured at baseline, 4 weeks and 8 weeks. The mean weight gain with amisulpride at 4 weeks was 2.73 kg (5.21%) and at 8 weeks was 4.34 kg (8.28%) from the baseline. The mean weight gain with blonanserin at 4 weeks was 1.77 kg (3.46%) and at 8 weeks was 3.46 kg (6.75%) from the baseline. The mean BMI increase at 8 weeks with amisulpride was 1.66 ± 0.56 and with blonanserin was 1.34 ± 0.77. The mean WHR increase at 8 weeks with amisulpride was 0.036 ± 0.026 and with blonanserin was 0.029 ± 0.020. There was statistically significant increase in weight, BMI and WHR associated with both blonanserin and amisulpride at 8 weeks. But there was no statistically significant difference in those parameters between blonanserin and amisulpride, at eight weeks. Even though there was no significant difference in the weight gain caused by blonanserin, in comparison with amisulpride, both these drugs individually caused significant weight gain at 8 weeks, which is in contrast with the earlier studies, which needs to be further evaluated.

Full Text Available Background Massage is a tactile/kinesthetic stimulation with biochemical and physiological effects on the body. Newborn infant massage stimulation given by mothers may promote maternal-infant bonding and attachment, enhance infant weight gain and stimulate the production of breast milk. There have been few studies on the effect of massage stimulation on weight gain in full term infants, and this topic remains controversial. Objective To examine the effect of massage stimulation on weight gain in full term infants. Methods This quasi-experimental study was held in Sanglah Hospital and Bunda Setia Maternity Clinic. Massage stimulation was performed by mothers once daily for a four week period. Massage stimulation was given to 30 full term infants and their weight gain was compared to 31 control infants who did not receive massages. Results There were no differences in subject characteristics between the massage and control groups. Median weight gain in the massage group was 1230 grams, while that in the control group was 830 grams (P=0.028. Conclusion Weight gain in full term infants in the massage group was significantly greater than that in the control group after 4 weeks.

Children with obstructive sleep apnoea commonly undergo adenotonsillectomy as first-line surgical treatment. This paper aimed to investigate whether this intervention was associated with weight gain after surgery in the paediatric population with obstructive sleep apnoea. Two independent researchers systematically reviewed the literature from 1995 to 2014 for studies on patients who underwent adenotonsillectomy with weight-based measurements before and after surgery. The databases used were Ovid Medline, Embase and PubMed. Six papers satisfied all inclusion criteria. Four of these papers showed a significant weight increase and the others did not. The only high quality, randomised, controlled trial showed a significant increase of weight gain at seven months follow up, even in patients who were already overweight before their surgery. The current evidence points towards an association between adenotonsillectomy and weight gain in patients with obstructive sleep apnoea in the short term.

Data describing the effects of weight gain across adulthood on overall health are important for weight control. To examine the association of weight gain from early to middle adulthood with health outcomes later in life. Cohort analysis of US women from the Nurses' Health Study (1976-June 30, 2012) and US men from the Health Professionals Follow-Up Study (1986-January 31, 2012) who recalled weight during early adulthood (at age of 18 years in women; 21 years in men), and reported current weight during middle adulthood (at age of 55 years). Weight change from early to middle adulthood (age of 18 or 21 years to age of 55 years). Beginning at the age of 55 years, participants were followed up to the incident disease outcomes. Cardiovascular disease, cancer, and death were confirmed by medical records or the National Death Index. A composite healthy aging outcome was defined as being free of 11 chronic diseases and major cognitive or physical impairment. A total of 92 837 women (97% white; mean [SD] weight gain: 12.6 kg [12.3 kg] over 37 years) and 25 303 men (97% white; mean [SD] weight gain: 9.7 kg [9.7 kg] over 34 years) were included in the analysis. For type 2 diabetes, the adjusted incidence per 100 000 person-years was 207 among women who gained a moderate amount of weight (≥2.5 kg to adulthood was associated with significantly increased risk of major chronic diseases and decreased odds of healthy aging. These findings may help counsel patients regarding the risks of weight gain.

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.

The objective of this study was to investigate the association of nutrient intake and pregnancy outcome mediated by weight gain during pregnancy, job status, and household income. Maternal age, educational level, self-reported pre-pregnancy weights, educational level, and household income were collected from the women at 2 months postpartum. For each offspring, weight at birth, length at birth, and gestational age were collected. Participants were asked to report the frequency of consumption of foods between 28-42 weeks into the pregnancy. Diet was assessed by using a validated 106-item semi-quantitative food-frequency questionnaire (SQFFQ) and women were asked portions and quantities based on pictures, food models, and measuring tools such as cups or teaspoons. Results showed that women who gained below the recommended weight gain during pregnancy, within, and over were 25.3%, 38.7%, 36.0%, respectively. In comparison to weight gain and the offspring's length and weight at birth, the offspring of mothers with a lower weight gain had a higher length. Energy, protein, vitamin B2, vitamin C, calcium, and potassium were significantly lower at employed group. We did not observe a significant difference between birth characteristics and maternal nutrient intake by income. Infants with a higher ponderal index at birth were born to women with a higher pre-pregnancy body mass index (BMI).
Full Text Available 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.

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. We recruited 36 healthy volunteers, who were randomized to either a standardized diet to gain ≈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 heart rate variability was performed at baseline, after weight gain, and after weight loss to determine the ratio of low-frequency to high-frequency power and to examine the relationship between changes in heart rate variability 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. Low frequency/high frequency 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 was seen that correlated consistently with changes in heart rate variability. Short-term fat gain in healthy subjects is associated with increased cardiac sympathetic activation during wakefulness and sleep, but the mechanisms remain unclear.

Objectives The Kangaroo method helps promote maternal breastfeeding and adequate growth of low birthweight preterm infants. The objective of this study was to analyze the association between weight-gain velocity during use of the Kangaroo method and maternal and infant variables. Methods A nested cross-sectional study in a cohort of newborn infants managed using the Kangaroo method was carried out at a reference center for the method in Brazil. Data on low birthweight and preterm infants managed using the Kangaroo Method (n = 78) and on their respective mothers (n = 70) was collected between January and July 2014. Maternal and infant variables were associated and correlated with weight-gain velocity (g/kg/day) at each phase of the method (p Kangaroo method. Birthweight of under 1500 g was associated with a lower likelihood of inadequate weight-gain velocity of the newborn at phase 1 (OR = 0.1; 95 % CI 0.01-0.78; p = 0.012). In phase 3, maternal age was directly correlated with weight-gain velocity. Conclusions Weight-gain velocity was associated with maternal (age) and infant (gestational age at birth, birthweight, weight for gestational age at birth, length of hospital stay and five-minute Apgar score) variables. Knowledge of the factors influencing weight-gain velocity and its behavior at each phase of the method can help guide conduct toward potentializing factors that promote adequate weight-gain.

To analyze the weight gain and to describe the metabolic complications in preterm newborns with nutritional support (NS) and to describe nutritional practices in the first month of hospitalization for 52 preterm newborns. Descriptive and prospective study of preterm infants (30-36 gestational weeks), with birth weight > 1 kg, hospital stay > 12 days, without respiratory support or complications, conducted at a public hospital in Leon, Guanajuato, Mexico from January to November 2006. Weight, serum glucose, insulin, cholesterol, triglycerides, gamma-glutamyltransferase, creatinine, urea nitrogen, type of NS (parenteral PN, enteral EN, mixed MN), energy content, and macronutrient intake were measured weekly. To obtain representative data, nutritional practices were not altered by the study protocol. One way ANOVA and Wilcoxon tests were used in data analyses. Overall, 52 newborns were included, averaging 33 gestational weeks and 1,590 g of weight. The NS was started by the fourth day on average. Parenteral nutrition was the most frequent NS during the first 2 weeks (75%). Energy and macronutrient supply was 50% less than the recommended. Weight gain ranged from -100 to 130 g/week. Parenteral nutrition showed better weekly weight gain, followed by EN. The metabolic complication rate per person-day was greater for MN (0.56), than for EN (0.16) or PN (0.09). Routine surveillance of weight and metabolic complications was deficient. Late onset of NS, insufficient energy supply, and deficient surveillance were obstacles to weight gain and to prevent the metabolic complications in these newborns.

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.

To determine the self-reported counselling practices of health care providers with regard to prenatal weight gain and the risks of inappropriate gain. We conducted a cross-sectional survey using a self-administered questionnaire at obstetrician, midwifery, and family medicine clinics in Hamilton, Ontario. Health care providers were eligible to participate if they provided prenatal care and could read English sufficiently well to complete the survey. Forty-two health care providers completed the survey; of these, 95% reported counselling women to gain a specific amount of weight, and 81% reported that they recommended values that were in accordance with the 2009 Institute of Medicine/Health Canada guidelines. The risks of excess and inadequate gain were reported as being discussed with their patients by 87% and 76% of health care providers, respectively. In this first study to the best of our knowledge of gestational weight gain counselling since the publication of the 2009 guidelines, most health care providers reported discussing weight gain and the risks of inappropriate gain, which is incongruent with previously published information on their patients' reports of counselling.

Full Text Available Obesity is an emerging major health risk for women around the world. In this regard, little attention has been given to pregnancy, a moment of risk not only for major weight gain in these women, but also for macrosomia in their offspring. The objective of this study is to evaluate weight gain during pregnancy. Data pertains to a cohort of pregnant women attending general prenatal care clinics in six state capitals in Brazil, from 1991 to 1995. We studied women aged 20 years and over with singleton pregnancies and no diagnosis of diabetes outside pregnancy, enrolled at approximately 20 - 28 weeks of gestation. According to the Institute of Medicine criteria, 38% (95%CI: 36-40% of the women studied gained less and 29% (95%CI: 28-31% had more than the recommended total weight gain. These proportions vary according to pre-pregnancy nutritional status. Given the increasing epidemic of obesity, the high prevalence of overweight and obesity in Brazilian women prior to pregnancy, and the lack of achievement of recommended weight gain during pregnancy, more effective means of managing weight gain during pregnancy are necessary.

Extreme weight changes, or changes in weight greater than 10 kg within a 2-year period, can be caused by numerous factors that are much different than typical weight fluctuations. This paper uses two interesting cases of extreme weight change (a female who experienced extreme weight gain and a male who experienced extreme weight loss) from participants in the Energy Balance Study to illustrate the physiological and psychosocial variables associated with the weight change over a 15-month period, including rigorous assessments of energy intake, physical activity (PA) and energy expenditure, and body composition. In addition, we provide a brief review of the literature regarding the relationship between energy balance (EB) and weight change, as well as insight into proper weight management strategies. The case studies presented here are then placed in the context of the literature regarding EB and weight change. This report further supports previous research on the importance of regular doses of PA for weight maintenance, and that even higher volumes of PA are necessary for weight loss. Practitioners should emphasize the importance of PA to their patients and take steps to monitor their patients' involvement in PA.

This study examined the relationship between therapeutic alliance and primary symptom change (weight gain) during CBT for anorexia nervosa. The aims were threefold: (1) to establish the strength of the therapeutic alliance across the treatment, (2) to determine whether early therapeutic alliance is associated with the completion of CBT for this client group, and (3) to determine the direction of the relationship between therapeutic alliance and weight gain. Adult outpatients (N=65) with a diagnosis of anorexia nervosa (or atypical anorexia nervosa) completed a measure of alliance at session six and at the end of treatment. Weight was recorded at the start of treatment, session six and at the end of treatment. The strength of the alliance was consistently high in the sample. However, early therapeutic alliance was not associated with either the likelihood of completing treatment or subsequent weight gain. In contrast, both early and later weight gain were associated with the strength of subsequent alliance. These findings indicate that it might be advisable to focus on techniques to drive weight gain rather than rely on the therapeutic alliance to bring about therapeutic change.

To investigate whether increments of weight gain in early infancy are related to the timing of adiposity rebound (AR). A total of 271 children (147 boys and 124 girls) in 1 community were enrolled in the study. Serial measurements of body mass index were carried out at the ages of 4, 8, and 12 months and 1.5, 2, 3, 4, 5, 6, 7, 8, 9, and 10 years, based on which the age of AR was determined. We also calculated body weight increments in 3 separate periods: birth to 4 months, 4-8 months, and 8-12 months. There was no significant relationship between weight gain in any period of infancy and the age of AR. Weight gain between birth and 4 months was positively correlated only with body mass index at 7 years of age. We could not find an association between body weight gain during infancy and the timing of AR. This suggests that infantile weight gain is not related to childhood obesity through AR.

Objective Food reinforcement is cross-sectionally related to body mass index and energy intake in adults, and prospectively predicts weight gain in children, but there has not been any research studying food reinforcement as a predictor of adult weight gain. Design and Methods This study examined whether the relative reinforcing value of food versus sedentary activities, as measured on a progressive ratio schedule, predicts 12 month weight gain. Dietary disinhibition and dietary restraint were also examined as potential moderators of this relationship, in a sample of 115 non-obese (Body Mass Indexreinforcement significantly increased the variance from 6.3% to 11.7% (p = 0.01) and predicted weight gain (p = 0.01). Dietary disinhibition moderated this relationship (p = 0.02) and increased the variance an additional 4.7% (p = 0.02), such that individuals with high food reinforcement had greater weight gain if they were also high in disinhibition. Conclusions These results suggest that food reinforcement is a significant contributor to weight change over time, and food reinforcement may have the biggest effect on those who are most responsive to food cues.

Excessive pregnancy weight gain is associated with adverse maternal and child health outcomes. Intervention developers have assumed that adopting a healthier diet and increasing physical activity in pregnancy can limit weight gain, but evaluations of such interventions have yielded mixed results. Recent reviews of this literature have not identified defining characteristics of effective interventions. We systematically reviewed 10 published controlled trials of interventions that aimed to reduce gestational weight gain through changes in diet or physical activity. Characteristics of the sample, intervention content and delivery, and methodology were categorized. Meta-analysis showed that, overall, diet and physical activity change was effective in reducing gestational weight gain, but there was considerable heterogeneity in outcomes. Our analysis points to sample characteristics and aspects of intervention design, content, delivery and evaluation which differ between studies and may explain variation in effectiveness. Failure to evaluate changes in behaviour or its psychological determinants, and under-reporting of intervention content, may obscure identification of the processes by which weight change is effected. This limits our ability to discern active intervention ingredients. We suggest that behaviour-based gestational weight gain reduction interventions be more systematically designed, evaluated and reported to build on insights from behavioural science. © 2011 The Authors. obesity reviews © 2011 International Association for the Study of Obesity.

OBJECTIVE: To assess birth weight in relation to gestational weight gain (GWG) among women who were and were not obese before pregnancy. METHODS: For a retrospective cohort study, data were obtained for women with a pre-pregnancy body mass index (BMI, calculated as weight in kilograms divided by ......±410g) or at least 40 (3671±374g) than among non-obese women (3394±453g; P=0.0058). CONCLUSION: Birth weight is related to both maternal BMI and GWG. In obese women, adherence to GWG recommendations does not seem to prevent increased birth weights....

The Institute of Medicine (IOM) guidelines are the most widely used guidelines on gestational weight gain; however, accumulation of evidence that body composition in Asians differs from other races has brought concern regarding whether their direct application is appropriate. We aimed to study to what extent optimal gestational weight gain among women in Japan differs by pre-pregnancy body mass index (BMI) and to compare estimated optimal gestational weight gain to current Japanese and Institute of Medicine (IOM) recommendations. We retrospectively studied 104,070 singleton pregnancies among nulliparous women in 2005-2011 using the Japanese national perinatal network database. In five pre-pregnancy BMI sub-groups (17.0-18.4, 18.5-19.9, 20-22.9, 23-24.9, and 25-27.4 kg/m 2 ), we estimated the association of the rate of gestational weight gain with pregnancy outcomes (fetal growth, preterm delivery, and delivery complications) using multivariate regression. Weight gain rate associated with the lowest risk of adverse outcomes decreased with increasing BMI (12.2 kg, 10.9 kg, 9.9 kg, 7.7 kg, and 4.3 kg/40 weeks) for the five BMI categories as described above, respectively. Current Japanese guidelines were lower than optimal gains, with the lowest risk of adverse outcomes for women with BMI below 18.5 kg/m 2 , and current IOM recommendations were higher than optimal gains for women with BMI over 23 kg/m 2 . Optimal weight gain during pregnancy varies largely by pre-pregnancy BMI, and defining those with BMI over 23 kg/m 2 as overweight, as proposed by the World Health Organization, may be useful when applying current IOM recommendations to Japanese guidelines.

Young adults attending college are more vulnerable to weight gain than the general population. We sought to identify health behavior change targets related to weight management in college students. Based on the social cognitive theory model for health behavior change, we investigated the health-related lifestyle behaviors and physiological characteristics of this population. Forty-three college students (18.3±0.1 years) completed a series of quantitative assessments (body weight and compositi...

Our aim was to investigate the association between gestational weight gain (GWG) and postpartum weight retention (PWR) in pre-pregnancy underweight, normal weight, overweight or obese women, with emphasis on the American Institute of Medicine (IOM) recommendations. We performed secondary analyses on data based on questionnaires from 1,898 women from the "Smoke-free Newborn Study" conducted 1996-1999 at Hvidovre Hospital, Denmark. Relationship between GWG and PWR was examined according to BMI as a continuous variable and in four groups. Association between PWR and GWG according to IOM recommendations was tested by linear regression analysis and the association between PWR ≥ 5 kg (11 lbs) and GWG by logistic regression analysis. Mean GWG and mean PWR were constant for all BMI units until 26-27 kg/m(2). After this cut-off mean GWG and mean PWR decreased with increasing BMI. Nearly 40% of normal weight, 60% of overweight and 50% of obese women gained more than recommended during pregnancy. For normal weight and overweight women with GWG above recommendations the OR of gaining ≥ 5 kg (11 lbs) 1-year postpartum was 2.8 (95% CI 2.0-4.0) and 2.8 (95% CI 1.3-6.2, respectively) compared to women with GWG within recommendations. GWG above IOM recommendations significantly increases normal weight, overweight and obese women's risk of retaining weight 1 year after delivery. Health personnel face a challenge in prenatal counseling as 40-60% of these women gain more weight than recommended for their BMI. As GWG is potentially modifiable, our study should be followed by intervention studies focusing on GW.

The Institute of Medicine and the National Research Council have issued new guidelines for gestational weight gain as well as recommendations for action and research that call for “a radical change in the care provided to women of childbearing age.” For the first time, these guidelines consider the outcomes of both mother and child during and after delivery and the trade-offs between them. The recommendations call for women to begin pregnancy at a healthy weight and to gain within the guidelines, a goal not previously achieved. They also call for individualized preconceptional, prenatal, and postpartum care to help women attain a healthy weight, gain within the guidelines, and return to a healthy weight. Scientific evidence was inadequate to provide specific guidelines by obesity class or to support a public health recommendation to reduce the guidelines below 5–9 kg (11–20 lb) for obese women.

The aim of the present study was to assess the impact of obesity and gestational weight gain on the risk of subtypes of preterm birth, because little is known about these associations. The study included 62 167 women within the Danish National Birth Cohort for whom self-reported information about...... prepregnancy body mass index (BMI) and gestational weight gain was available. Information about spontaneous preterm birth with or without preterm premature rupture of membranes (PPROM) and about induced preterm deliveries was obtained from national registers. Cox regression analyses were used to examine...... associations of prepregnancy BMI and gestational weight gain with subtypes of preterm birth. The crude risks of PPROM and of induced preterm deliveries were higher in obese women (BMI > or = 30) than in normal-weight women (18.5

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.

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 increase together with fat mass (P weight increase together with fat mass (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.

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.

Full Text Available Several studies suggest that the holiday season, starting from the last week of November to the first or second week of January, could be critical to gaining weight. This study aims to review the literature to determine the effects of the holidays on body weight. In studies of adults, a significant weight gain was consistently observed during this period (0.4 to 0.9 kg, p0.05 during this period. Among individuals with obesity who attempt to lose weight, an increase in weight was observed (0.3 to 0.9 kg, significant in some but not in all studies, as well as increase in weight in motivated self-monitoring people (0.4 to 0.6%, p<0.001. Programs focused on self-monitoring during the holidays (phone calls and daily mailing appeared to prevent weight gain, but information is limited. The holiday season seems to increase body weight in adults, even in participants seeking to lose weight and in motivated self-monitoring people, whereas in children, adolescents, and college students, very few studies were found to make accurate conclusions.

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...

Full Text Available The objective of the papper was to verify the relationship between dietary intake and interdialytic weight gain in patients with chronic kidney disease. Cross-sectional study, in a renal clinic in Irati, Paraná, Brazil. Prehemodialysis weight and weight after hemodialysis were evaluated. Food intake was analyzed according to food frequency and usual food day (DAH. The data were evaluated descriptively and also through the chi-square test, Student's t-test and Mann-Whitney test. Sixty-one patients (54.1% participated in the study, with a mean age of 57.78±14.58 years, 62.3% of males. The mean pre-hemodialysis weight was 68.28±15.14 kg, while hemodialysis was 65.63±15.01 kg (p0.05. The other food groups (meat, cereals, fats and sweets also had no association with weight gain (p> 0.05. When the nutrients were compared, according to the DAH, there was no relation with the interdialytic weight gain (p>0.05. Thus, it was observed that there was a relationship between interdialytic weight gain and macronutrient consumption; The same was not observed for micronutrients.

To examine the associations between sleep problems and major weight gain during a 5- to 7-year follow-up among middle-aged women and men. The Helsinki Health Study prospective cohort baseline survey data from 2000 to 2002 (n = 8960, response rate 67%) among 40- to 60-year-old municipal employees and follow-up survey data from 2007 (n = 7332, response rate 83%) were used. Logistic regression analysis was used to examine the association between the four-item Jenkins Sleep Questionnaire and major weight gain of 5 kg or more over a 5- to 7-year follow-up. Half of the participants reported at least occasional sleep problems, whereas 13% of women and 17% of men reported no such problems at baseline. The frequency of sleep problems varied by item. Frequent sleep problems were reported by 20% of women and 17% of men. Major weight gain was reported by 25% of women and 24% of men. Trouble falling asleep (odds ratio (OR) 1.65; 95% confidence interval (CI) 1.22, 2.22), waking up several times per night (OR 1.49; 95% CI 1.22, 1.81) and trouble staying asleep (OR 1.41; 95% CI 1.13, 1.75) were associated with major weight gain during the follow-up in women but not in men. In contrast, waking up tired was unassociated with weight gain. The summary measure of the four items was also associated with weight gain in women. Adjusting for baseline body mass index, physical health, health behaviour, marital status, education, work arrangements and sleep duration had only minor effects on the above associations. Adjusting for common mental disorders at baseline, the associations were attenuated but remained for trouble falling asleep, waking up several times per night and trouble staying asleep. Occasional sleep problems were also associated with weight gain. Sleep problems likely contribute to weight gain. To prevent major weight gain and obesity, sleep problems need to be taken into account.

The purpose of this study was to determine the information that pregnant women report receiving when being counseled about weight gain and the risks of inappropriate gain. With the use of a self-administered questionnaire at prenatal clinics in Hamilton, Ontario, Canada, a cross-sectional survey was conducted of women who had had at least 1 prenatal visit, who could read English, and who had a live singleton gestation. Three hundred ten women completed the survey, which was a 93.6% response rate. Although 28.5% (95% confidence interval, 23.5-33.6%) reported that their health care provider had made a recommendation about how much weight they should gain, only 12.0% (95% confidence interval, 8-16.1%) of the women reported having achieved the recommended weight gain in accordance with the 2009 guidelines. One quarter of the women reported being told that there were risks with inappropriate gain. Despite the recent 2009 publication of the gestational weight gain guidelines, only 12% of women reported being counseled correctly, which suggests an urgent need for improved patient education.

We sought to evaluate inadequate gestational weight gain and fetal growth among overweight and obese women. We conducted an analysis of prospective singleton term pregnancies in which 1053 overweight and obese women gained >5 kg (14.4 ± 6.2 kg) or 188 who either lost or gained ≤5 kg (1.1 ± 4.4 kg). Birthweight, fat mass, and lean mass were assessed using anthropometry. Small for gestational age (SGA) was defined as ≤10th percentile of a standard US population. Univariable and multivariable analysis evaluated the association between weight change and neonatal morphometry. There was no significant difference in age, race, smoking, parity, or gestational age between groups. Weight loss or gain ≤5 kg was associated with SGA, 18/188 (9.6%) vs 51/1053 (4.9%); (adjusted odds ratio, 2.6; 95% confidence interval, 1.4-4.7; P = .003). Neonates of women who lost or gained ≤5 kg had lower birthweight (3258 ± 443 vs 3467 ± 492 g, P women who gained ≤5 kg had significantly lower birthweight, lean body mass, fat mass, percent fat mass, head circumference, and length. There were no significant differences in neonatal outcomes between those who lost weight and those who gained ≤5 kg. In overweight and obese women weight loss or gain ≤5 kg is associated with increased risk of SGA and decreased neonatal fat mass, lean mass, and head circumference. Copyright © 2014 Mosby, Inc.

Cigarette smokers are generally known to gain weight after quitting smoking, and such weight gain is thought to contribute to the worsening of glucose tolerance. While smoking cessation therapy such as nicotine replacement is useful to minimize post-cessation weight gain, substantial gain occurs even during the therapy. The purpose of the present study was to identify factors associated with weight gain during smoking cessation therapy. We evaluated 186 patients(132 males and 54 females)who visited our outpatient clinic for smoking cessation, and successfully achieved smoking abstinence. We performed gender-adjusted regression analysis for the rate of BMI increase from the beginning of cessation to 3 months after initiation. Furthermore, we performed multivariate analysis to investigate factors that determine the BMI increase after smoking cessation. The mean BMI significantly (ptherapy. There was no significant difference in the extent of BMI increase between nicotine patch and varenicline therapy groups. Factors significantly correlated with the %BMI increase at 3 months after the start of therapy were triglyceride (p = 0.0006, βa = 0.260), high-density lipoprotein cholesterol (p = 0.0386, βa = -0.168), daily cigarette consumption (p = 0.0385, βa = 0.154), and the Fagerström Test for Nicotine Dependence (FTND) score (p = 0.0060, βa = 0.203). Stepwise multivariate analysis demonstrated that triglyceride and the FTND score were the factors determining the post-cessation BMI increase and that the FTND score was the strongest one. The present study demonstrated that smokers with a high FTND score are more likely to gain weight during smoking cessation therapy. Thus, smokers with a high nicotine dependency may require intervention against weight gain in the cessation clinic.
Full Text Available Abstract Background Obesity and weight gain are correlated with psychological ill health. We predicted that childhood emotional problems and self-perceptions predict weight gain into adulthood. Methods Data on around 6,500 individuals was taken from the 1970 Birth Cohort Study. This sample was a representative sample of individuals born in the UK in one week in 1970. Body mass index was measured by a trained nurse at the age of 10 years, and self-reported at age 30 years. Childhood emotional problems were indexed using the Rutter B scale and self-report. Self-esteem was measured using the LAWSEQ questionnaire, whilst the CARALOC scale was used to measure locus of control. Results Controlling for childhood body mass index, parental body mass index, and social class, childhood emotional problems as measured by the Rutter scale predicted weight gain in women only (least squares regression N = 3,359; coefficient 0.004; P = 0.032. Using the same methods, childhood self-esteem predicted weight gain in both men and women (N = 6,526; coefficient 0.023; P N = 6,522; coefficient 0.022; P Conclusion Emotional problems, low self-esteem and an external locus of control in childhood predict weight gain into adulthood. This has important clinical implications as it highlights a direction for early intervention strategies that may contribute to efforts to combat the current obesity epidemic.

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. © 2014 International Parkinson and Movement Disorder Society.

To provide perspective to the most recent evidence regarding the association between early weight gain in infancy and the development of asthma and atopy during childhood, and highlight the potential mechanisms involved. Recently, several birth cohort studies involving more than 25 000 children have found a consistent association between early weight gain in the first 2 years of life and incident asthma during school age. Methodology differs substantially between the studies and complicates the establishment of definite conclusions. Specific mechanisms for this association have been proposed, including impairment in lung development and elevated levels of growth factors and cytokines associated with airway inflammation and remodeling. A limited number of studies indicate that early weight gain in infancy is also associated with recurrent wheezing during preschool age but not with the development of atopy. A consistent association between early weight gain in infancy and incident asthma during school age has been observed in several cohort studies. The identification of this modifiable risk factor for the development of asthma opens the possibility of preventive intervention. Additional studies are necessary to clarify the involved mechanisms and some pending questions, such as the influence of early weight gain in asthma phenotypes and severity.

To investigate the changes of regional cerebral blood flow (rCBF) in early-onset anorexia nervosa (AN) before and after weight gain, we examined resting rCBF using single photon emission computed tomography (SPECT) with [(123)I]iodoamphetamine ((123)I-IMP). Ten female children with AN (mean age 13.2 years old) participated in this study. SPECT examinations were performed in all patients twice at the beginning of treatment and after weight gain. The mean body mass index (BMI) was changed from 13.1 to 16.6 during 4 months treatment period. Automatic voxel-based analysis of the images was carried out using statistical parametric mapping (SPM) software. Relatively increased rCBF in the bilateral parietal lobe and limbic lobe including the posterior cingulate cortex (PCC) were observed after weight gain in early-onset AN. There was no significant decrease in the rCBF after weight gain. A significant positive correlation was observed between BMI and rCBF in the right thalamus, right parietal lobe, and right cerebellum. These results suggested that weight gain during the process of recovery from early-onset AN might activate specific brain regions which are possibly relevant to the pathophysiological aspects of the disorder.

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.

Increasing physical activity in pregnancy may improve pregnancy outcomes for obese women. Exercise could reduce gestational weight gain, improve the maternal circulating lipid profile as well as alter leptin, Interleukin-8 (IL-8) and Monocyte Chemoattractant Protein-1 (MCP-1) levels. The aim of this study was to investigate the effects of exercise on gestational weight gain, maternal circulating lipids, IL-8, MCP-1 and leptin levels in obese pregnant women. The analysis was performed in the 35 obese women enrolled in the pilot BAMBINO randomised controlled trial who provided blood samples at 12- and 28-weeks gestation. Women in the exercise intervention arm received an individualised exercise plan. Blood samples, exercise diary and pedometer data were obtained at 12-, 20-, 28- and 36-weeks' gestation. Cord blood was obtained at delivery. Women in the exercise arm exercised more than those in the control arm (P = 0.038). There was no difference in gestational weight gain, excess gestational weight gain, MCP-1 and leptin levels between women in the exercise intervention (n = 19) or the control arm (n = 16). IL-8 was not detectable. Exercise did not alter the maternal lipid profile. The low level of physical activity achieved in obese women in the exercise intervention arm was insufficient to alter gestational weight gain, MCP-1, leptin or circulating lipid levels. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

An association between antibiotic use and excessive weight gain or obesity in healthy infants and young children has been reported, but evidence is inconsistent and based on observational studies of growth in relation to incidental antibiotic exposures. To evaluate whether prolonged antibiotic exposure is associated with weight gain in children participating in a clinical trial of antibiotic prophylaxis to prevent recurrent urinary tract infection. Secondary analysis of data from the Randomized Intervention for Children With Vesicoureteral Reflux Study, a 2-year randomized clinical trial that enrolled participants from 2007 to 2011. All 607 children who were randomized to receive antibiotic (n = 302) or placebo (n = 305) were included. Children with urinary tract anomalies, premature birth, or major comorbidities were excluded from participation. Trimethoprim-sulfamethoxazole or placebo taken orally, once daily, for 2 years. Weight gain as measured by change in weight-for-age z score from baseline to the end-of-study visit at 24 months. Secondary outcomes included weight gain at 6, 12, and 18 months and the prevalence of overweight or obesity at 24 months. Participants had a median age of 12 months (range, 2-71 months) and 558 of 607 (91.9%) were female. Anthropometric data were complete at the 24-month visit for 428 children (214 in the trimethoprim-sulfamethoxazole group and 214 in the placebo group). Weight gain in the trimethoprim-sulfamethoxazole group and the placebo group was similar (mean [SD] change in weight-for-age z score: +0.14 [0.83] and +0.18 [0.85], respectively; difference, -0.04 [95% CI, -0.19 to 0.12]; P = .65). There was no significant difference in weight gain at 6, 12, or 18 months or in the prevalence of overweight or obesity at 24 months (24.8% vs 25.7%; P = .82). Subgroup analyses showed no significant interaction between weight gain effect and age, sex, history of breastfeeding, prior antibiotic use, adherence to study

Despite the high prevalence of overweight among Hispanic children in the United States, definitive predictors of weight gain have not been identified in this population. The study objective was to test sociodemographic, metabolic, and behavioral predictors of 1-y weight gains in a large cohort of Hispanic children studied longitudinally. Subjects (n = 879) were siblings from 319 Hispanic families enrolled in the Viva la Familia Study. Families were required to have at least one overweight child aged 4-19 y. One-year changes in weight and body composition by dual-energy X-ray absorptiometry were measured. Data were from parental interviews, birth certificates, multiple-pass 24-h dietary recalls, 3-d accelerometry, 24-h respiration calorimetry, measurements of eating in the absence of hunger, and measurement of fasting blood biochemistry indexes by radioimmunoassay. Generalized estimating equations and principal component analysis were applied. Weight gain increased with age (P = 0.001), peaking at approximately 10 y of age in girls and approximately 11 y of age in boys. Mean (+/-SD) weight gain was significantly higher in overweight (7.5 +/- 3.7 kg/y) than in nonoverweight (4.4 +/- 2.4 kg/y) children and in boys than in girls. When adjusted for age, age squared, sex, and Tanner stage, the final model indicated a child's body mass index (BMI; kg/m2) status, maternal BMI, energy expenditure (total energy expenditure, basal metabolic rate, and sleeping metabolic rate), and fasting blood biochemistry indexes (total triiodothyronine, insulin, leptin, and ghrelin) as independent, positive predictors of weight gain (P = 0.01-0.001). Knowledge of the metabolic and behavioral predictors of weight gain in Hispanic children will inform prevention and treatment efforts to address this serious public health problem in the United States.

To determine if gestational weight gain (GWG) in adolescents is associated with long-term weight increases 12 years and 18 years after delivery of a first child and the differential effects of weight gain during pregnancy that is inadequate, the appropriate amount, and excessive based on the 2009 Institute of Medicine (IOM) recommendations. Secondary data analysis of data from a randomized controlled trial. Memphis, Tennessee. Two hundred ninety-eight (298) primiparous low-income Black women who were adolescents at the time of their first pregnancies. Linear regression was used to examine the relationship between body mass index (BMI) at 12 and 18 years postdelivery and GWG, parity, prepregnancy BMI, and smoking. The total sample experienced a significant BMI increase from prepregnancy to 12 years and 18 years postdelivery. More than 50% of the women had a BMI increase greater than 10 kg/m(2) . By 18 years postdelivery, 85% were overweight or obese. Prepregnancy BMI and GWG had a positive significant effect on BMI 12 and 18 years later, whereas smoking had a negative effect. Those who gained excessive weight based on the IOM recommendations had a significantly higher BMI compared with those who gained appropriately. Gestational weight gain had long-term effects on BMI in a minority adolescent population. Excessive pregnancy weight gain is likely to contribute to long-term weight retention, especially if adolescents are overweight or obese when they become pregnant with their first children. Intervention during pregnancy to limit GWG has the potential of limiting long-term negative health consequences that result from overweight and obesity in minority women. © 2013 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

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.

Objectives To examine clinical and demographic characteristics associated with availability of self-reported and measured pre-pregnancy weight, differences in these parameters, and characteristics associated with self-report accuracy. Methods Retrospective cohort of 7483 women who delivered at a large academic medical center between 2011 and 2014. Measured pre-pregnancy weights recorded within a year of conception and self-reported pre-pregnancy weights reported anytime during pregnancy were abstracted from electronic medical records. Difference in weights was calculated as self-reported minus measured pre-pregnancy weight. Logistic and linear regression models estimated associations between demographic and clinical characteristics, and presence of self-reported and measured weights, and weight differences. Results 42.2% of women had both self-reported and measured pre-pregnancy weight, 49.7% had only self-reported, and 2.8% had only measured. Compared to white women, black women and women of other races/ethnicities were less likely to have self-reported weight, and black, Asian, and Hispanic women, and women of other races/ethnicities were less likely to have measured weights. For 85%, pre-pregnancy BMI categorized by self-reported and measured weights were concordant. Primiparas and multiparas were more likely to underreport their weight compared to nulliparas (b = -1.32 lbs, 95% CI -2.24 to -0.41 lbs and b = -2.74 lbs, 95% CI -3.82 to -1.67 lbs, respectively). Discussion Utilization of self-reported or measured pre-pregnancy weight for pre-pregnancy BMI classification results in identical categorization for the majority of women. Providers may wish to account for underreporting for patients with a BMI close to category cutoff by recommending a range of gestational weight gain that falls within recommendations for both categories where feasible.

High dietary energy density (ED) has been associated with weight gain. However, little is known about the long-term effects of ED on weight changes among free-living subjects, particularly in Japanese and other Asian populations. In this study, we assessed dietary habits and weight changes in participants (5778 males and 7440 females, 35-69 years old) of the Takayama study. ED was estimated using a validated FFQ at baseline only. Information on body weight (BW) was obtained by self-administered questionnaires at baseline and follow-up. Mean BW difference in 9·8 years was 17 (se 4221) g for men and -210 (se 3889) g for women. In men, ED was positively associated with BW at follow-up after controlling for age, BW, height, physical activity score, alcohol consumption, energy intake, years of education at the baseline and change of smoking status during the follow-up. On average, men in the highest quartile of ED (>5·322 kJ/g (>1·272 kcal/g)) gained 138 (se 111) g, whereas men in the lowest ED (lost 22 (se 111) g (P for trend=0·01). The association between ED and BW gain was stronger in men with normal weight. In women, the association between ED and weight change was not statistically significant. In conclusion, contrary to some studies that report an association between ED and weight gain in the overweight only, our data suggest that high-ED diets may be associated with weight gain in the lean population as well, at least in male subjects.

Full Text Available 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.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.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.

Weight gain and metabolic disturbances represent serious side-effects in antipsychotic (AP) treatment, particularly with clozapine and olanzapine. The methylenetetrahydrofolate reductase (MTHFR) gene is a key determinant in the folate metabolism and previous studies reported a significant effect on AP-induced weight gain and related metabolic abnormalities. Thus, we investigated MTHFR gene variants and changes in several important metabolic parameters in AP-treated patients. In this study, two functional MTHFR polymorphisms, rs1801133 (C677T) and rs1801131 (A1298C), were investigated for changes in weight and metabolic parameters. Genotypic associations were evaluated in a large population (n = 347 including 66 first episode psychosis, FEP patients) treated mostly with clozapine and olanzapine. We did not detect any genotypic association with weight changes (p > 0.05) in our total sample and in the sample refined for ancestry and medication. In our allelic analyses, we observed a trend for the 677-C allele to be associated with weight gain in the total sample (p = 0.03). This effect appeared to be driven by the FEP patients where those carrying the C-allele gained, on average, twice as much weight. Exploratory analyses revealed a significant association between the C677T and the A1298C polymorphism with HDL cholesterol serum levels in patients (p = 0.031). Overall we did not detect a major effect of two functional MTHFR gene variants and AP-induced weight gain. However, our findings suggest an effect of the C677T polymorphism in FEP patients and changes in weight and cholesterol levels. Further investigations in a larger sample are required.

Obese and overweight women have an increased risk of breast cancer and worse outcomes at the time of diagnosis. Women tend to gain weight after breast cancer diagnosis and during chemotherapy for early-stage disease, which may in turn increase risk for worse outcomes. We examined if weight gained during adjuvant chemotherapy was associated with worse survival outcomes. We queried our database for data on patients who received adjuvant third-generation chemotherapy for early-stage breast cancer. Univariate and multivariate analyses by Cox regression were performed for survival outcomes across three categories according to BMI variation from start to end of chemotherapy: >0.5 kg/m(2) loss or gain and stable BMI (±0.5 kg/m(2) ). We included 1998 patients in this study. Women over 50 years old and postmenopausal were more likely to lose weight during adjuvant chemotherapy, whereas women under 30 years old gained more weight (P original weight (ρ = -0.3, P 0.5 kg/m(2) compared to maintaining BMI was marginally associated with increased locoregional recurrence risk (HR: 2.53; 95% CI, 1.18-5.45; P = 0.017), adjusting for grade, stage, and radiation delivery. Weight variation during adjuvant chemotherapy for early-stage breast cancer may occur as both weight gain and weight loss in a balanced manner. Furthermore, this variation seems to be transient in nature and does not appear to significantly influence recurrence rates and overall survival. © 2017 The Authors.

The purpose of this study was to 1) investigate lifetime weight changes in community dwelling old-old, those age 80 or older; 2) explore reasons for weight changes from their personal perspective and 3) examine ways the old-old feel they can successfully lose weight. A cross sectional design was used for this qualitative study. One county of a southeastern U.S. state. Nine community dwelling old-old. Content analysis of transcripts was used to examine the interviews. All of the old-old interviewed had reached their maximum weight after the age of 65. Average lifetime weight gain was 73 pounds. All wanted to lose weight and found ways to incorporate small changes in their everyday lives. With increasing life expectancy among older adults, health promotion targeting weight control needs to include the old-old.

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.

A prospective study of chronotype as a predictor of increased weight gain and body mass index (BMI) among college freshman was undertaken. At baseline, 137 college freshmen were characterized as morning, neutral, or evening types using the reduced version of the Morningness-Eveningness Questionnaire. Additionally, information was collected regarding weight, BMI, and health habits (e.g., junk food and alcohol consumption). These additional measures consisted of a descriptive questionnaire, the Pittsburgh Sleep Quality Index, the International Physical Activity Questionnaire, the Gray-Donald Eating Patterns Questionnaire, and the Positive and Negative Affect Scale. Participants included 79 females and 80 males with a mean age of 18.25 (SD = 0.56) yrs. Eight weeks later, participants returned (N = 54) to complete follow-up measures, which were identical to baseline assessments with the exception of the descriptive questionnaire, in which demographic questions were removed. Evening types had a significantly greater BMI gain (p weight gain relationship.

significantly lowered their intakes of added sugars and saturated fat and increased their protein intake by ~1% of total energy compared to controls. Of these dietary variables only intakes of added sugar appeared to be related to GWG, while no association was observed for saturated fat or protein. Further...... analyses revealed that foods that contributed to intake of added sugars, including sweets, snacks, cakes, and soft drinks were strongly associated with weight gain, with women consuming sweets ≥2/day having 5.4 kg (95% CI 2.1-8.7) greater weight gain than those with a low (... for soft drinks were more conflicting, as women with high weight gain tended to favour artificially sweetened soft drinks. CONCLUSION: In our sample of obese pregnant women, craving for sweets, snacks, and soft drinks strongly predicts GWG. Emphasis on reducing intakes of these foods may be more relevant...

The United States has the unenviable distinction of having both the highest obesity rate among Organisation for Economic Co-operation and Development (OECD) member countries and the highest incarceration rate in the world. Further, both are socially patterned by race/ethnicity and socioeconomic position. Incarceration involves various health behaviors that could influence adult weight trajectory. We evaluated the associations between history and duration of adult incarceration and weight gain using the National Survey of American Life (N=6082 adults residing in the 48 contiguous states between February 2001 and March 2003). We propensity score-matched individuals to control for the probability of having a history of incarceration. To examine the relation between prior incarceration and adult weight gain, we fit gender-stratified generalized estimating equations controlling for propensity of incarceration history, age, education, income, race/ethnicity, and marital status. For males (N=563), incarceration was associated with about a 1.77 kg/m(2) lower gain in body mass index (BMI) during adulthood, after adjusting for age, education, income, race/ethnicity, and marital status in addition to the propensity of having a history of incarceration (95% CI: -2.63, -0.92). For females (N=286), no significant overall relationship was found between a history of incarceration and adult weight gain. In subgroup analyses among those with an incarceration history, we found no overall association between duration of incarceration and adult weight gain in men or women. In sensitivity analyses, neither tobacco smoking nor parity changed the results. The results of this study indicate that incarceration is associated with a lower transition of weight gain in males, but not in females.. Copyright © 2015 Elsevier Inc. All rights reserved.

Counselling women for and managing birth after caesarean section are important. Research is needed on evaluation of antenatal factors that predict likelihood of successful trial of labour after caesarean section (TOLAC). To evaluate the effect of gestational weight gain on mode of delivery in women having TOLAC. A retrospective cohort study of eligible women who underwent TOLAC (January 2012 to July 2015) at a large urban hospital. Gestational weight gain was classified as 'excessive' or 'not excessive' based on calculated pre-pregnancy body mass index. Multivariable logistic regression analysis was performed to estimate the association of gestational weight gain and vaginal birth, adjusting for socio-demographic and pregnancy-related factors. Of 534 women, those who gained excessive weight were less likely to have a vaginal birth as women who did not (adjusted odds ratio (aOR) 0.48, 95% confidence interval (CI) 0.29-0.81)). Women with previous vaginal birth were more likely to have a vaginal birth (aOR 3.74, 95% CI 1.90-7.36), while women ≥35, women who had an epidural, and women who delivered at 40 weeks, were less likely (aOR 0.58, 95% CI 0.35-0.97, aOR 0.12, 95% CI 0.07-0.22, and aOR 0.53, 95% CI 0.31-0.91, respectively). Gaining excessive weight in pregnancy is potentially modifiable, and can be incorporated into individual antenatal counselling, and into risk prediction models, to assist with informed decision making around planned mode of delivery in women with previous caesarean section. Future research could focus on interventions to reduce gestational weight gain in women planning TOLAC. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.
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.

Purpose To review the recently issued guidelines for weight gain during pregnancy. Recent findings These guidelines were developed to minimize the negative health consequences for both mother and fetus of inadequate or excessive gain. They call for categorizing women’s prepregnancy body mass index using the WHO/NHLBI cutoff points and provide ranges of recommended weight gain for underweight (28–40 lb), normal-weight (25–35 lb), overweight (15–25 lb) and obese (11–20 lb) gravidas. Data were insufficient to construct specific guidelines for women with class II or class III obesity. Women should attempt to conceive at a normal weight for better obstetric outcomes. Improved comprehensive preconceptional care is necessary to help women reach this goal. Most American women currently gain below or above the new ranges, so changes are required in both women’s behavior and how their care is managed. Data from a variety of interventions related to improved diet and increased physical activity show that individualized care can assist women in gaining within these guidelines. Summary The guidelines offer many opportunities for obstetrician/gynecologists, together with ancillary health care providers, to assume a larger role as “women’s health care physicians” and to conduct research that could improve the health of mothers and children.

Obesity is a major health problem world-wide. Medical intervention is often needed to tackle this problem, and accordingly the need for developing more effective, safer and cheaper weight reducing drugs has become paramount in recent years. In the present study, the effects of lime (Citrus aurantifolia) essential oils in reducing body weight, individually and in co-administration with ketotifen, an antihistaminic drug that causes weight gain, has been investigated using a mouse model. During the 45 days experimental period, the mice that received ketotifen demonstrated an enhancement both in the amount of food intake and body weight compared with the control group. Groups treated with lime essential oil displayed a reduction in body weight and food consumption in mice, possibly through promoting anorexia which might have played a role in weight loss. Interestingly, co-administration of the lime essential oil and ketotifen caused significant suppression in gaining weight, as well as decreased body weights of mice. The data obtained in this study suggested that lime essential oil plays an important role in weight loss and could be useful in the treatment of drug-induced obesity and related diseases. The GC-MS analysis of the essential oils of C. aurantifolia was also performed and approximately 22 main components, with limonene (28.27%) being the principal one, were identified and quantified.

There are significant variations in gestational weight gain, with many women gaining in excess of the Institute of Medicine guidelines. Unfortunately, efforts to improve appropriate gestational weight gain have had only limited success. To date, interventions have focused primarily on decreasing energy intake and/or increasing physical activity. Maternal resting energy expenditure, which comprises ∼60% of total energy expenditure compared with the ∼20% that comes from physical activity, may be an important consideration in understanding variations in gestational weight gain. Our objective was to quantify the changes in resting energy expenditure during pregnancy and their relationship to gestational weight gain and body composition changes among healthy women. We hypothesized that greater gestational weight gain, and fat mass accrual in particular, are inversely related to variations in resting energy expenditure. We conducted a secondary analysis of a prospective cohort studied before conception and late pregnancy (34-36 weeks). Body composition (estimated using hydrodensitometry) and resting energy expenditure (estimated using indirect calorimetry) were measured. The relationship between the changes in resting energy expenditure and gestational weight gain and the change in fat mass and fat-free mass were quantified. Resting energy expenditure was expressed as kilocalories per kilogram of fat-free mass per day (kilocalories per kilogram of fat-free mass-1/day-1) and kilocalories per day. Correlations are reported as r. Among 51 women, preconception body mass index was 23.0 (4.7) kg/m2; gestational weight gain was 12.8 (4.7) kg. Preconception and late pregnancy resting energy expenditure (kilocalories per day) correlated positively with the change in fat-free mass (r = 0.37, P = .008; r = 0.51, P = .001). Late-pregnancy resting energy expenditure (kilocalories per kilogram of fat-free mass-1/day-1) was inversely associated with the change in fat mass (r
Full Text Available Castration is a controversial practice in swine production because in some countries is still performed without anaesthesia, and therefore causes intense suffering and stress to animals. This study investigated the effect of pre-surgical administration of local anaesthesia (LA on the growth performance of piglets until the end of the growth phase (102 days. Piglets aged 3 to 5 days were selected in pairs of similar weights and same age. They were originated from 22 litters. The groups were randomly assigned to one of two treatments. Castration was performed with (LA; n = 45 or without (NLA; n = 45 intra-testicular administration of 0.5 mL of 2% lidocaine plus adrenaline per testicle, administered by an automatic repeating vaccinator. Castration was performed 10 min later. Average daily weight gain and economic impact were evaluated between the intervals before castration until 21 (weaning phase, before castration until 60 (end of the initial nursery phase and before castration until 102 (growth phase days of age. Average daily weight gain data were analyzed by comparing the average daily weight gain between the weaning phase, 60 and 102 days of age versus the initial weight (pre-castration. At the end of the growing phase, animals treated with LA showed greater weight gain than animals castrated without anaesthesia. LA also showed improved cost:benefit ratio and theore might provide greater economic benefit under the conditions used in this study. Our findings have proved that castration with LA improves long-term weight gain of piglets.

Childhood obesity rates have reached epidemic proportions. Excessive weight gain in infancy is associated with persistence of elevated weight status and later obesity. In this review, we make the case that weight gain in the first 6 mo is especially predictive of later obesity risk due to the metabolic programming that can occur early postpartum. The current state of knowledge regarding the biological determinants of excess infant weight gain is reviewed, with particular focus on infant feeding choice. Potential mechanisms by which different feeding approaches may program the metabolic profile of the infant, causing the link between early weight gain and later obesity are proposed. These mechanisms are likely highly complex and involve synergistic interactions between endocrine effects and factors that alter the inflammatory and oxidative stress status of the infant. Gaps in current knowledge are highlighted. These include a lack of data describing 1) what type of infant body fat distribution may impart risk and 2) how maternal metabolic dysfunction (obesity and/or diabetes) may affect milk composition and exert downstream effects on infant metabolism. Improved understanding and management of these early postnatal determinants of childhood obesity may have great impact on reducing its prevalence.

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.

Smoking cessation-related weight gain can have significant negative health and career consequences for military personnel. Alcohol reduction combined with smoking cessation may decrease weight gain and relapse. A randomized clinical trial of military beneficiaries compared a standard smoking cessation (i.e., brief informational) intervention (N=159), with a brief motivational smoking cessation intervention that emphasized reduced drinking to lessen caloric intake and minimize weight gain (N=158). Participants who received the motivational intervention were significantly more likely to quit smoking at the 3-month follow-up (p=0.02), but the differences were not maintained at 6 (p=0.18) or 12months (p=0.16). Neither weight change nor alcohol reduction distinguished the 2 groups. Smoking cessation rates at 12months (motivational group=32.91%, informational group=25.79%) were comparable to previous studies, but successful cessation was not mediated by reduced drinking. Alcohol reduction combined with smoking cessation did not result in decreased weight gain or improved outcomes. Copyright © 2017. Published by Elsevier Ltd.

Childhood obesity is a serious public health issue. Understanding environmental factors and their contribution to weight gain is important if interventions are to be effective. The purpose of this research was to assess the relationship between weight gain in children and accessibility of fast-food outlets. A longitudinal sample of 1577 children was created using two time points from the National Child Measurement Programme in South Gloucestershire (2006/7 and 2012/13). A spatial analysis was conducted using a weighted accessibility score on the number of fast-food outlets within a 1-km network radius of each child's residence to quantify access to fast food. The mean accessibility score for all children was 0.73 (standard deviation: 1.14). Fast-food outlets were more prevalent in areas of deprivation. A moderate association was found between deprivation score and accessibilty score (r = 0.4, P Children who had greater access to fast-food outlets were more likely (odds ratio = 1.89, P = 0.04) to gain significant weight (>50 percentile points) compared to children who had no access to fast-food outlets. This paper supports previous research that fast-food outlets are more prevalent in areas of deprivation and presents new evidence on fast-food outlets as a potential contributor towards weight gain in mid-childhood.

Background: Human and animal studies report a blunted sense of taste in people who are overweight or obese, with heightened sensitivity also reported after weight loss. However, it is unknown if taste changes concurrently with weight gain. Objective: This study investigated the association of weight gain with changes in suprathreshold taste intensity perception in a free-living population of young adults. Methods: Taste response, anthropometric measures, and diet changes were assessed with a longitudinal study design in first-year college students 3 times throughout the academic year. At baseline, 93 participants (30 males, 63 females) were an average of 18 y old, with a body mass index (in kg/m 2 ) of 21.9. Sweet, umami, salty, sour, and bitter taste intensities were evaluated at 3 concentrations by using the general Labeled Magnitude Scale. Ordinary least-squares regression models assessed the association of weight gain and within-person taste change, adjusting for sex, race, and diet changes. Results: Participants gained an average of 3.9% in weight, ranging from -5.7% to +13.8%. With each 1% increase in body weight, males perceived sweet and salty as less intense, with taste responses decreasing by 11.0% (95% CI: -18.9%, -2.3%; P = 0.015) and 7.5% (95% CI: -13.1%, -1.5%; P = 0.015) from baseline, respectively. Meanwhile, females did not experience this decrement, and even perceived a 6.5% increase (95% CI: 2.6%, 10.5%; P = 0.007) in sour taste with similar amounts of weight gain. Changes in the consumption of meat and other umami-rich foods also negatively correlated with umami taste response (-39.1%; 95% CI: -56.3%, -15.0%; P = 0.004). Conclusions: A modest weight gain is associated with concurrent taste changes in the first year of college, especially in males who experience a decrement in sweet and salty taste. This suggests that young-adult males may be susceptible to taste loss when gaining weight. © 2017 American Society for Nutrition.

Overweight and obesity have been associated with unemployment but less is known about changes in weight associated with changes in employment. We examined weight changes associated with job-loss, retirement and maintaining employment in two samples of working adults in the United Kingdom. This was a prospective study of 7201 adults in the European Prospective Investigation of Cancer (EPIC)-Norfolk study (aged 39-76 years) and 4539 adults in the British Household Panel Survey (BHPS) who were followed up over 43 months and 26 months, respectively. In both samples, changes in measured (EPIC) and self-reported (BHPS) weight were computed for each participant and assessed in relation to three employment transitions: maintaining paid employment, retirement and job-loss. Regression models adjusted for potential confounders. Further analyses evaluated the contribution of diet, physical activity and smoking to weight gain. In EPIC-Norfolk, weight change differed across the three employment transitions for women but not men. The mean (95% CI) annualised change in weight for women who became unemployed over the follow-up period was 0.70 (0.55, 0.85) kg/y while those who maintained employment gained 0.49 (0.43, 0.55) kg/y (P = 0.007). Accounting for changes in smoking, diet and physical activity did not substantially alter the difference in weight gain among groups. In BHPS, job-loss was associated with weight gain of 1.56 (0.89, 2.23) kg/y, while those who maintained employment 0.60 (0.53, 0.68) kg/y (P changes associated with retirement were similar to those staying in work. In BHPS, job-loss was also associated with significant declines in self-reported well-being and increases in sleep-loss. Two UK-based samples of working adults reveal strong associations between job-loss and excess weight gain. The mediating behaviours are so far unclear but psychosocial mechanisms and sleep-loss may contribute to the excess weight gain among individuals who become unemployed. Copyright

The United States has the unenviable distinction of having both the highest obesity rate among Organisation for Economic Co-operation and Development (OECD) member countries and the highest incarceration rate in the world. Further, both are socially patterned by race/ethnicity and socioeconomic position. Incarceration involves various health behaviors that could influence adult weight trajectory. We evaluated the associations between history and duration of adult incarceration and weight gain...

Background Smoking cessation has been reported to be associated with high total gestational weight gain (GWG), which itself is a risk factor for adverse maternal-infant outcomes. Recent studies have criticized conventional single measures of GWG, since they may lead to biased results. Therefore, we aimed to compare patterns of GWG based on serial antenatal weight measurements between women who: never smoked, quit during pregnancy, continued to smoke. Methods Participants (N?=?509) of our long...

Obesity is a risk factor for developing Barrett's esophagus (BE), a precursor to esophageal cancer. Long BE lengths are associated with greater risk for malignancy. How weight gains from young adulthood (defined as ages 19 to 29 years) affect BE length is unknown. To examine current body mass index (BMI), weight gains from young adulthood, and evening snacking near bedtime during young adulthood in BE patients. Cross-sectional analysis of 71 patients from 2001 to 2008 from a 600-bed tertiary care center in the United States who were newly diagnosed with BE by endoscopy and mucosal biopsies. Barrett's esophagus length and age at presentation. Pearson's correlation coefficient (r) measured the linear association between continuous variables. The Kruskal-Wallis test was used to compare medians by segment length and the chi-squared test or Fisher's exact test for categorical data. Quantile regression was used for multivariable adjustment. Younger patients had higher BMIs at diagnosis (r=-0.32, P=0.007). Patients who gained more than 23 kg from young adulthood were diagnosed at an adjusted median age of 18.0 years younger 95% CI (6.1-29.9, P=0.004) than patients with no weight gains. BMI was not correlated with BE length (r=-0.12, P=0.33). Weight gains from young adulthood were not associated with BE length after multivariable adjustment (P=0.19). Patients whose late evening snack or bedtime was less than 4 hours from dinner had longer median BE lengths than those who went to bed later (5 vs 2 cm, P=0.02). Longer BE lengths were associated with shorter dinner-bedtime intervals during young adulthood but not with current BMI or weight gains from young adulthood.

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.

Full Text Available We evaluate pastures formed of Pennisetum purpureum cv.cameroon and Urochloa brizantha.cv. Marandu aiming at greater live weight gains per animal and per hectare. The animals were crossbred male half blood Tabapuã/Nellore live weight of 280 kg (9.3 kilos. Each grass was submitted to four stocking rates in a rotated grazing system with three days of grazing and 36 days of rest, resulting in a 39 days grazing cycle. In the summer the stocking rates were 2.64, 3.49, 4.34 and 5.09 UA/ha in and winter the rates were 164, 2.38, 3.26 and 3.89 UA/ha. In summer, the stocking rate of 4.34 UA/ha enabled best combination between weight gain per animal and per area with daily average gains of 0.560kg/animal and 2.99 kg/ha on cameroon grass and of 0.505 kg/animal and 2.79 kg/ha for braquiarão grass. However, in winter, the stocking rate of 3.26 UA/ha was the one which enabled greatest animal yield with daily average gains of 0.670kg/animal and 2.86 kg/ha on cameroon grass and 0.503 kg/animal and 2.10kg/ha on braquiarão grass. The weight gain per animal and per area is influenced by stocking rate. The cameroon grass provides greater weight than grass braquiarão gains, both animal as per area, in both rainy and dry seasons.

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.

Examine sleep restriction's effects on weight gain, daily caloric intake, and meal timing. Repeated-measures experiments assessing body weight at admittance and discharge in all subjects (N = 225) and caloric intake and meal timing across days following 2 baseline nights, 5 sleep restriction nights and 2 recovery nights or across days following control condition nights in a subset of subjects (n = 37). Controlled laboratory environment. Two hundred twenty-five healthy adults aged 22-50 y (n = 198 sleep-restricted subjects; n = 31 with caloric intake data; n = 27 control subjects; n = 6 with caloric intake data). Approximately 8-to-1 randomization to an experimental condition (including five consecutive nights of 4 h time in bed [TIB]/night, 04:00-08:00) or to a control condition (all nights 10 h TIB/night, 22:00-08:00). Sleep-restricted subjects gained more weight (0.97 ± 1.4 kg) than control subjects (0.11 ± 1.9 kg; d = 0.51, P = 0.007). Among sleep-restricted subjects, African Americans gained more weight than Caucasians (d = 0.37, P = 0.003) and males gained more weight than females (d = 0.38, P = 0.004). Sleep-restricted subjects consumed extra calories (130.0 ± 43.0% of daily caloric requirement) during days with a delayed bedtime (04:00) compared with control subjects who did not consume extra calories (100.6 ± 11.4%; d = 0.94, P = 0.003) during corresponding days. In sleep-restricted subjects, increased daily caloric intake was due to more meals and the consumption of 552.9 ± 265.8 additional calories between 22:00-03:59. The percentage of calories derived from fat was greater during late-night hours (22:00-03:59, 33.0 ± 0.08%) compared to daytime (08:00-14:59, 28.2 ± 0.05%) and evening hours (15:00-21:59, 29.4 ± 0.06%; Ps sleep restriction promoted weight gain. Chronically sleep-restricted adults with late bedtimes may be more susceptible to weight gain due to greater daily caloric intake and the consumption of calories during late-night hours

The purpose of this study was to investigate associations between body weight and illness characteristics, including weight gain and therapeutic efficacy, in adolescents with schizophrenia. Adolescents ages 13-17 years (n = 107) with American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) schizophrenia enrolled in a 6 week, double-blind, placebo-controlled trial comparing olanzapine and placebo. Therapeutic response was assessed by the Brief Psychiatric Rating Scale for Children (BPRS-C). Secondary outcomes included the Clinical Global Impressions-Severity (CGI-S) scale and Positive and Negative Syndrome Scale (PANSS). Obesity was defined as sex-/age-adjusted body mass index (BMI) ≥ 95th percentile. Linear regression was used to analyze the relationship between weight gain and psychiatric symptom improvement; logistic regression was conducted to identify predictors of baseline obesity. Weight gain was significantly correlated with greater BPRS-C reduction among olanzapine-treated subjects (r = -0.31, ptreatment (p=0.12), and a treatment by weight gain interaction did not emerge in a repeated-measures mixed model analysis that included time in the study (t = 1.27, p = 0.21). Additionally, weight gain ≥ 7% was not significantly associated with response or remission. Among 17 adolescents (16%) with obesity at study entry, obesity was not significantly associated with endpoint BPRS-C illness severity. However, girls (p = 0.03), individuals hospitalized within the past year (p = 0.02), and those with less severe overall (p = 0.03) and negative symptoms (p = 0.003) according to the CGI-S and PANSS negative subscale, respectively, were more likely to be obese at baseline. Baseline obesity was associated with lower illness severity, which could be mediated by greater treatment adherence, leading to more weight gain. Olanzapine-related weight gain was not independently associated with symptomatic outcome when controlling
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

Preterm birth is a disease of multifactorial etiologies that has environmental, social, and maternal health components. Individual studies have shown that exposure to arsenic contaminated drinking water, child marriage, and low maternal weight gain during pregnancy contribute to preterm birth. These factors are highly prevalent and often co-exist in Bangladesh, a country in South Asia with one of the world's highest prevalences of preterm birth. To evaluate the individual and interactive effects of prenatal arsenic exposure, child marriage, and pregnancy weight gain on preterm birth in a prospective birth cohort in Bangladesh. During 2008-2011, we recruited 1613 pregnant women aged ≥18years at ≤16weeks of gestation and followed them until 1-month post-partum. We measured total arsenic in drinking water (n=1184) and in maternal toenails (n=1115) collected at enrollment and ≤1-month post-partum, respectively using inductively coupled plasma mass spectrometry. Child marriage (child marriage, and 0.64 (95% CI: 0.42-0.97) for a pound per week increase in maternal weight during the 2nd and 3rd trimesters. In stratified analysis by child marriage, pregnancy weight gain was inversely associated with preterm birth among women with a history of child marriage (RR=0.58; 95% CI: 0.37-0.92), but not among women with no history of child marriage (RR=86; 95% CI: 0.37-2.01). Mediation analysis revealed that both arsenic exposure and child marriage had small but significant associations with preterm birth via lowering pregnancy weight gain. Similar associations were observed when arsenic exposure was assessed using maternal toenail arsenic concentrations. Reducing arsenic exposure and ending child marriage could reduce the risk of preterm birth in Bangladesh. Furthermore, enhancing nutritional support to ensure adequate weight gain during pregnancy may provide additional benefits especially for women with a history of child marriage.

Full Text Available Worldwide, different guidelines are used to assess the adequacy of gestational weight gain. This study identified the recommendations for gestational weight gain in Brazilian women. We also determined the proportion of women with adequate weight gain in accordance with these recommendations and the associated perinatal outcomes. A systematic review was performed. A computerized search was conducted utilizing the following databases: PubMed, MEDLINE, Web of Science, Embase, SciELO and Google Scholar. Observational studies of healthy, Brazilian, pregnant women were included. Studies were excluded if they did not provide pregestational weight and gestational weight gain or if they studied women with comorbid conditions. A meta-analysis was performed to evaluate the odds ratio of inadequate (insufficient or excessive gestational weight gain. Seventeen studies were included in the systematic review and four studies were included in the meta-analysis. The most widely used recommendations were from the Institute of Medicine. Excessive gestational weight gain was associated with fetal macrosomia and high rates of cesarean delivery. Overweight women had a higher risk of excessive gestational weight gain than eutrophic women (OR=2.80, 95%CI=2.22-3.53. There are no standardized recommendations concerning gestational weight gain based on Brazilian population-based data. Many Brazilian women are overweight or obese at the beginning of pregnancy. Overweight pregnant women have a higher risk of excessive gestational weight gain. Excessive gestational weight gain was associated with cesarean delivery and fetal macrosomia.

To explore attitudes toward weight gain during pregnancy in women with and without eating disorders and across eating disorder subtypes, and to examine associations among weight-gain attitudes and actual gestational weight gain, infant birth weight, and infant size-for-gestational-age. Pregnant women (35,929) enrolled in the prospective population-based Norwegian mother and child cohort study (MoBa) provided information at approximately week 18 of gestation regarding eating disorders and weight gain attitudes. We explored these variables in women with anorexia nervosa, bulimia nervosa, eating disorder not otherwise specified, purging type, and binge eating disorder (BED). The presence of an eating disorderly was associated with greater worry over gestational weight gain. In women without eating disorders, greater worry was associated with higher gestational weight gain, higher infant weights, greater likelihood of a large-for-gestational-age infant, and reduced likelihood of a small-for-gestational-age infant. Women with BED who reported greater worry also experienced higher weight gains during pregnancy. Women with eating disorders tend to experience weight-gain-related worry during pregnancy. Early worry about gestational weight-gain may be a harbinger of high gestational gain.

Retrospective review of patients from a multicenter database. To evaluate the nutritional status of children with thoracic insufficiency syndrome (TIS) and to determine if treatment with vertical expandable prosthetic titanium ribs (VEPTR) leads to improvements in weight percentile. Children with pulmonary insufficiency characteristically have poor nutrition as the energy expenditure from the extra work of breathing approaches the nutritional gain of eating. To our knowledge, no previous studies have examined the relation between VEPTR and potential nutritional improvements in children with TIS. Seventy-six patients at 7 different institutions underwent placement of VEPTR devices for treatment or prevention of TIS. Mean age at surgery was 3.7 years (range, 8 months-14 years). All patients were observed for a minimum of 24 months with an average follow-up of 3.3 years (range, 2-6 years). Before surgery and at each postoperative visit, patients were weighed and the Cobb angle was measured. All weights were converted to normative percentiles based on the patient's age. Overall, we found a significant increase in the percentile of patients' weights after VEPTR surgery (P = 0.0004). Of the 76 patients in our series, 60 (79%) were 5 percentile weight before surgery, 50% (8/16) had increased weight percentiles after surgery. For most patients, the majority of weight gain occurred between 4 and 8 months after surgery; weight gain continued up to 48 months after surgery. The change in Cobb angle had no relation to the change in weight percentile. A total of 79% of patients with TIS were less than 5 percentile in weight, thus meeting the criteria for "failure to thrive." Our study demonstrates a significant improvement in the nutritional status of these children after VEPTR surgery, which is an important outcome measure in this population.

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.

The aim of the study was to assess weight changes after traumatic brain injury (TBI) in children and the factors influencing them. We conducted a longitudinal observational study of children with TBI of mixed severity who were consecutively admitted to one rehabilitation department (39 children; 23 males, 16 females; median age 8y 7mo; 25th to 75th centiles 3y 7mo-11y 6mo). Weight and height before TBI were obtained from the children's records and were measured monthly for 1 year after TBI. Body mass index (BMI) and BMI z-scores were calculated, and pre-TBI values were compared with the final values using paired tests. Linear mixed-effect interaction models were used to assess the effect of various factors on z-score evolution. Z-score curves revealed early weight loss followed by a rapid increase in weight. The mean BMI gain over the period under study was 0.9 kg/m² (p children had become overweight by the time of final assessment. Factors associated with a greater rate of increase in the post-TBI z-score were mobility restriction, male sex, and older age. Global pre- to post-TBI weight gain was significantly higher in males (z-score 0.7). Pituitary hormonal testing was available for 17 children at 3 months and for 27 at 1 year. Growth hormone deficiency was detected in one child. Weight gain of children during the first year after TBI was rapid and excessive. Male sex was a risk factor for excessive weight gain. © The Authors. Developmental Medicine & Child Neurology © 2012 Mac Keith Press.

To examine whether excessive recreational Internet time, insufficient sleep, regular coffee consumption, or alcoholic beverages promote weight gain. A longitudinal cohort of >5000 girls (Growing Up Today Study), from all over the United States and aged 14 to 21 years, returned surveys in 2001 reporting typical past-year recreational Internet time, sleep, coffee (with caffeine), and alcohol consumption. We estimated correlations among these 4 exposures. Each girl also reported her height and weight in 2000 and again in 2001. Multivariate models investigated associations between 1-year change in body mass index and same-year exposures, adjusted for adolescent growth/development, activity, and inactivity. The exposures were highly (P .50). More Internet time, more alcohol, and less sleep were all associated (P gained more body mass index from 2000 to 2001. For females in weight-promoting categories of all exposures, this translates to nearly 4 extra pounds gained over 1 year. We found no evidence that drinking coffee promotes weight gain. Older girls may benefit from replacing recreational Internet time with sleep and by avoiding alcohol.

Full Text Available Goals/Background. To evaluate children’s growth in the first year of life, who have cleft palate and lip, without the use of palatal plates. Materials/Method. Chart review was conducted, retrospectively, in the Center for Integral Assistance of Cleft Lip and Palate (CAIF, in Brazil, between 2008 and 2009. Results for both genders were compared to the data published by the World Health Organization (WHO regarding average weight gain in children during their first year of life. Results. Patients with syndromic diagnosis and with cleft classified as preforamen were excluded, resulting in a final number of 112 patients: 56 male and 56 female. Similar patterns were seen comparing the two genders. Although it was observed weight gain below the average until the 11th month in male patients and until 9 months in female patients, both genders remained at the 50th percentile (p50 and improved after the 4th month of age for boys and the 9th month of age for girls. Conclusion. Children with cleft palate weigh less than regular children during their first months of life. At the end of the first year, weight gain is similar comparing normal and affected children. However, factors that optimized weight gain included choosing the best treatment for each case, proper guidance, and multiprofessional integrated care.

Grey world algorithm is a simple but widely used global white balance method for color cast images. However, this algorithm only assumes that the mean values of the R, G, and B components tend to be equal, which may lead to false alarms in some normal images with large areas of single color background, for example, images in ocean background. Another defect is that grey world algorithm may cause luminance variations in the channels having no cast. We note that though different in mean values, standard deviations of the three channels are supposed to converge in color cast images, which is not suitable for those false alarms. Based on this discrepancy, through a mathematical manipulation both on mean values and standard deviations of the three channels, a novel color correction model is proposed by weighting the gain coefficients in grey world model. All the three weighted gain coefficients in the proposed model tend to be 1 on images containing large single color regions so as to avoid false alarms. For the color cast images, the channel existing color cast is given a weighted gain coefficient much less than 1 to correct color cast, while the other two channels are distributed weighted gain coefficients approximately equal to 1 thus to ensure that the proposed model has little negative effects on channels with no color cast. Experiments show that our model presents better performance in color correction.

Childhood bullying has long-term negative mental and physical health correlates, including weight gain and symptoms of depression. The purpose of this research is to examine whether bullying in the first year of school is associated with greater weight gain by early adolescence and whether adolescent depressive symptoms mediate this association. Data were drawn from the Longitudinal Study of Australian Children. Children (N = 3929) were measured every 2 years; BMI and waist circumference were available from ages 4 to 15. Parents reported on bullying at age 6. Children reported on their depressive symptoms at ages 12-13. Participants who weighed in the obese category at age 4 had an over 50% increased risk of being bullied in school at age 6. Being bullied at age 6 was associated with excess weight gain between ages 6 and 15, defined as either BMI or waist circumference. Depressive symptoms at age 12 partially explained the association between bullying and increases in adiposity. None of the associations varied by gender. Similar to other forms of peer victimization, bullying early in school is associated with greater weight gain through early adolescence; depressive symptom is one mechanism that contributes to this association.

We sought to determine the impact of maternal weight gain on fetal growth in gestational diabetes (GDM) in relation to treatment modality, body mass index (BMI) and glycemic control. Two thousand four hundred fifty-four GDMs were evaluated. Obesity was defined as BMI >29; good glycemic control ≤ 100 mg/dl; maternal age 30 years; parity ± 1; large for gestational age (LGA) >90th percentile and small for gestational age (SGA) diet-treated women in glycemic control showed a four-fold higher rate of LGA compared to insulin-treated women. A 36-lb weight gain in insulin-treated patients had a six-fold higher risk. In poor glycemic control, LGA rates were higher in all BMI/weight gain categories. Logistic regressions for LGA/SGA revealed that level of glycemia, weight gain, parity, obesity and treatment (for LGA only) were significant. Different thresholds used for different maternal BMI categories in addition to the achievement of glycemic control and pharmacological therapy will enhance pregnancy outcome.

To model the hypothetical impact of preventing excessive gestational weight gain on midlife obesity and compare the estimated reduction with the US Healthy People 2020 goal of a 10% reduction of obesity prevalence in adults. We analyzed 3917 women with 1 to 3 pregnancies in the prospective US National Longitudinal Survey of Youth, from 1979 to 2012. We compared the estimated obesity prevalence between 2 scenarios: gestational weight gain as reported and under the scenario of a hypothetical intervention that all women with excessive gestational weight gain instead gained as recommended by the Institute of Medicine (2009). A hypothetical intervention was associated with a significantly reduced estimated prevalence of obesity for first (3.3 percentage points; 95% confidence interval [CI] = 1.0, 5.6) and second (3.0 percentage points; 95% CI = 0.7, 5.2) births, and twice as high in Black as in White mothers, but not significant in Hispanics. The population attributable fraction was 10.7% (95% CI = 3.3%, 18.1%) in first and 9.3% (95% CI = 2.2%, 16.5%) in second births. Development of effective weight-management interventions for childbearing women could lead to meaningful reductions in long-term obesity.

Food reinforcement, the extent to which people are willing to work to earn a preferred snack food, and parental obesity are risk factors for weight gain, but there is no research comparing the predictive effects of these factors for adolescent weight gain. 130 non-obese adolescents (M age=15.2 ± 1.0; M BMI=20.7 ± 2.0; M zBMI=0.16 ± 0.64) at differential risk for weight gain based on parental obesity completed baseline food and money reinforcement tasks, and provided zBMI data over a 2-year follow-up. The number of obese (BMI ≥ 30) parents (p=0.007) and high food reinforcement (p=0.046) were both significant independent predictors of greater zBMI increases, controlling for age, sex, parent education and minority status. Having no obese parents or being low or average in food reinforcement was associated with reductions in zBMI, but those high in food reinforcement showed larger zBMI increases (0.102) than having one obese parent (0.025) but less than having two obese parents (0.177). Food reinforcement and parental obesity independently predict future weight gain among adolescents. It might be fruitful for obesity prevention programs to target both high risk groups.

Full Text Available Objective. To evaluate the relationship of physical activity (PA and sedentary behaviour with gestational weight gain (GWG and birth weight. Design. Combined data from two prospective studies: (1 nulliparous pregnant women without BMI restrictions and (2 overweight and obese pregnant women at risk for gestational diabetes. Methods. Daily PA and sedentary behaviour were measured with an accelerometer around 15 and at 32–35 weeks of gestation. The association between time spent in moderate-to-vigorous PA (MVPA and in sedentary activities with GWG and birth weight was determined. Main outcome measures were GWG between 15 and 32 weeks of gestation, average GWG per week, and birth weight. Results. We studied 111 women. Early in pregnancy, 32% of women spent ≥30 minutes/day in at least moderate PA versus 12% in late pregnancy. No significant associations were found between time spent in MVPA or sedentary behaviour with GWG or birth weight. Conclusions. We found no relation between MVPA and sedentary behaviour with GWG or birth weight. The small percentage of women meeting the recommended levels of PA indicates the need to inform and support pregnant women to maintain regular PA, as there seems to be no adverse effect on birth weight and maintaining PA increases overall health.

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.

Recent studies have shown an association between weight change and the makeup of the intestinal microbiota in humans. Specifically, Lactobacillus, a part of the entire gastrointestinal tract's microbiota, has been shown to contribute to weight regulation. We examined the association between the level of oral Lactobacillus and the subsequent 6-year weight change in a healthy population of 322 Danish adults aged 35-65 years at baseline. Prospective observational study. In unadjusted analysis the level of oral Lactobacillus was inversely associated with subsequent 6-year change in BMI. A statistically significant interaction between the baseline level of oral Lactobacillus and the consumption of complex carbohydrates was found, e.g. high oral Lactobacillus count predicted weight loss for those with a low intake of complex carbohydrates, while a medium intake of complex carbohydrates predicted diminished weight gain. A closer examination of these relations showed that BMI change and Lactobacillus level was unrelated for those with high complex carbohydrate consumption. A high level of oral Lactobacillus seems related to weight loss among those with medium and low intakes of complex carbohydrates. Absence, or a low level of oral Lactobacillus, may potentially be a novel marker to identify those at increased risk of weight gain. © 2017 The Author(s) Published by S. Karger GmbH, Freiburg.

Depression and weight change are linked, but there is a paucity of studies on their association during clinical treatment. The present study investigated how risk factors for a weight gain of at least 10% (major weight gain) and mental health modify their mutual association during a 6-year prospective follow-up of depressed outpatients. The study sample consisted of 121 depressed treatment-seeking outpatients with a mean age of 44.9 years. A 6-year follow-up started in January 1996. At baseline and on follow-up after 2 and 6 years, psychiatric diagnoses were obtained using the Structured Clinical Interview for DSM-III-R (SCID-I), while cluster C personality disorders (PD) were assessed on 6-month follow-up (SCID-II). Depression was also assessed with the Hamilton Rating Scale for Depression (HAM-D) and general psychopathology with the Symptom Checklist-90 (SCL-90) at baseline and at the end of the 6-year follow-up. Weight changes were based on measurements at baseline and at the end of the follow-up. Logistic regression was used to study the factors associated with major weight gain (≥ 10%). Altogether, 16% of the study sample experienced major weight gain during the 6-year follow-up. Adverse childhood/adolescent experiences as a self-perceived cause of depression (OR 3.72, 95% CI 1.06-13.1, p=0.040), higher scores in the HAM-D (OR 1.11, 95% CI 1.02-1.22, p=0.019) and the SCL-90 subscale of anxiety (OR 2.22, 95% CI 1.11-4.42, p=0.023) at baseline, and cluster C PD at 6 months (OR 3.16, 95% CI 1.11-8.97, p=0.031) were separately associated with major weight gain after adjusting for age, gender, and baseline body mass index (BMI). The severity of depressive and anxiety symptoms and linking adverse childhood with depression at the beginning of treatment, as well as cluster C PD at 6 months, were predictors of major weight gain.

Two independent guidelines on appropriate weight gain for Japanese pregnant women have been established in 1997 and 2006. This study aimed to evaluate changes in the amount of gestational weight gain in pregnant women, the birth weight of their neonates, and the incidence of complications of pregnancy and neonatal outcome in women who delivered at Hyogo Prefectural Kaibara Hospital. Between 1988 and 2014, 6367 women delivered live singleton neonates at full term. The study period was divided into period I (1988-1996), period II (1997-2005), and period III (2006-2014). Changes in weight gain and birth weight were assessed. Complications of pregnancy and neonatal outcome were compared among the periods. Weight gain had been decreased in periods I and II, and weight gain was increased in period III. There was no difference in birth weights between the periods. The incidences of pregnancy-induced hypertension in periods II and III were higher than that in period I (pwomen.

Although there is growing evidence that higher adiposity increases ovarian cancer risk, little is known about its impact in African American (AA) women, the racial/ethnic group with the highest prevalence of obesity. We evaluated the impact of body mass index (BMI) 1 year before diagnosis and weight gain since age 18 years on ovarian cancer risk in a population-based case-control study in AA women in 11 geographical areas in the US. Cases (n = 492) and age and site matched controls (n = 696) were identified through rapid case ascertainment and random-digit-dialing, respectively. Information was collected on demographic and lifestyle factors, including self-reported height, weight at age 18 and weight 1 year before diagnosis/interview. Multivariable logistic regression was used to compute odds ratios (OR) and 95% confidence intervals (CI), adjusting for potential covariates. Obese women had elevated ovarian cancer risk, particularly for BMI ≥ 40 kg/m(2) compared to BMI risk per 5 kg/m(2) of BMI and 6% (95% CI: 1.01-1.10) increase in risk per 5 kg of weight gain. Excluding hormone therapy users essentially did not change results. Obesity and excessive adult weight gain may increase ovarian cancer risk in post-menopausal AA women. © 2016 UICC.

Evidence is lacking regarding effective weight control treatments in pregnancy for ethnic minority women with obesity. This study evaluated whether a technology-based behavioral intervention could decrease the proportion of African American women with overweight or obesity who exceeded Institute of Medicine (IOM) guidelines for gestational weight gain. We conducted a two-arm pilot randomized clinical trial. Participants were 66 socioeconomically disadvantaged African American pregnant women (12.5 ± 3.7 weeks' gestation; 36% overweight, 64% obesity) recruited from two outpatient obstetric practices at Temple University between 2013 and 2014. We randomized participants to usual care (n = 33) or a behavioral intervention (n = 33) that promoted weight control in pregnancy. The intervention included: (1) empirically supported behavior change goals; (2) interactive self-monitoring text messages; (3) biweekly health coach calls; and (4) skills training and support through Facebook. The intervention reduced the proportion of women who exceeded IOM guidelines compared to usual care (37% vs. 66%, P = 0.033). Intervention participants gained less weight during pregnancy (8.7 vs. 12.3 kg, adjusted mean difference: -3.1 kg, 95% CI: -6.2 to -0.1). No group differences in neonatal or obstetric outcomes were found. The intervention resulted in lower prevalence of excessive gestational weight gain. © 2015 The Obesity Society.

Efforts are under way to identify successful strategies to reduce long-term childhood obesity risk, such as ways to improve diet quality. To identify foods and beverages associated with excess weight gain, we used cohort data from the Avon Longitudinal Study of Parents and Children in the United Kingdom. We quantified the associations between changes in or levels of consumption of twenty-seven food and beverage groups and excess weight gain in three-year periods among youth ages 7-13. When we considered all dietary factors and physical activity levels simultaneously, we found that foods with the largest positive associations with three-year excess weight gain were fat spread (butter or margarine), coated (breaded or battered) poultry, potatoes cooked in oil (French fries, roasted potatoes, and potato chips), coated fish, processed meats, other meats, desserts and sweets, milk, and sugar-sweetened beverages. Foods associated with weight loss were whole grains and high-fiber cereals. These results provide evidence for targeting specific food and beverage groups in efforts to influence weight outcomes.

Previous research suggests that sleep duration is associated with obesity and weight gain. However, the majority of these studies are of cross-sectional design, with only a few cohort studies. In order to validate previous findings in a more real-world context, we evaluated the association between sleep duration, obesity, and weight gain in a large, 3-year cohort study. A retrospective cohort study was conducted involving 21,469 apparently healthy individuals aged 20 years or older who underwent annual health check-ups at the Center for Preventive Medicine, St. Luke's International Hospital, between 2005 and 2008. The participants were divided into four groups according to their self-reported average nightly sleep duration (≤5, 6, 7, and ≥8 h). We identified individuals with obesity (body mass index ≥25 kg/m(2)) and weight gain. Multivariate linear regression analysis and logistic regression analysis were used to explore the association between these variables and sleep duration, adjusting for age, gender, alcohol consumption, current smoking, past medical history, and level of physical activity. Compared with those who slept 7 h, the individuals who slept ≤5 h night were more likely to experience weight gain (β coefficient = 0.03; 95% CI = 0.03-1.1) and to become obese (OR = 1.5; 95% CI = 1.1-2.0). No significant difference was seen between subjects who slept more than 8 h and those sleeping 7 h (OR = 1.3; 95% CI = 0.9-1.8). Short sleep (≤5 h) is significantly associated with weight gain and obesity in both male and female adults.

To investigate the effect of pre- and postdischarge interventions on breastfeeding outcomes and weight gain among preterm infants. PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) database were searched for study selection using MeSH terms infant/premature, breastfeeding, weight gain, patient discharge, postnatal care, and counseling. Inclusion criteria included studies that involved preterm infants who were born less than or equal to 37 weeks of gestation, randomized controlled trials that were in English, conducted in developed countries, and had breastfeeding and weight gain outcomes. A total of 8 articles met inclusion criteria. All data related to breastfeeding outcomes including duration, exclusivity, maternal satisfaction, and weight gain were extracted from the randomized controlled trials for the purpose of data synthesis. A total of 310 studies were reviewed. Eight randomized controlled trials met the inclusion criteria. Gestational age of the infants in the studies ranged from 26 to 37 weeks. The results revealed that kangaroo care, peer counseling, in-home breast milk intake measurement, and postdischarge lactation support improved breastfeeding outcomes among preterm infants, and that maternal satisfaction improved with postdischarge interventions. No significant evidence of pre- and postdischarge interventions on weight gain was found. Pre- and postdischarge interventions were effective in promoting breastfeeding exclusivity, duration, and maternal satisfaction among mothers of preterm infants. These findings have important clinical implications that support the need for evidence-based breastfeeding interventions for preterm infants before discharge and vigilant postdischarge support. Research to determine more effective interventions to promote exclusive and long-term breastfeeding among preterm infants is required.

Low concentrations of plasma adiponectin, the most abundant adipose-specific protein, are observed in obese individuals and predict the development of type 2 diabetes. Administration of adiponectin to rodents prevented diet-induced weight gain, suggesting a potential etiologic role...... of hypoadiponectinemia in the development of obesity. Our aim was to prospectively examine whether low plasma adiponectin concentrations predict future weight gain in Pima Indians, explaining the predictive effect of adiponectin on the development of type 2 diabetes.

Objectives To examine whether excessive recreational Internet time, insufficient sleep, regular coffee consumption, or alcoholic beverages promote weight gain. Study design A longitudinal cohort of >5000 girls (Growing Up Today Study), from all over the US and aged 14–21yrs, returned surveys in 2001 reporting typical past-year recreational Internet time, sleep, coffee (with caffeine) and alcohol consumption. We estimated correlations among these four exposures. Each girl also reported her height and weight in 2000 and again in 2001. Multivariate models investigated associations between 1-year change in body mass index (BMI) and same-year exposures, adjusted for adolescent growth/development, activity and inactivity. Results The exposures were highly (pcoffee with Internet time (p>0.50). More Internet time, more alcohol, and less sleep were all associated (pdrinking coffee promotes weight gain. Conclusions Older girls may benefit from replacing recreational Internet time with sleep and by avoiding alcohol. PMID:18614178

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

To compare objective and subjective weight gain of second-generation antipsychotics in schizophrenia and bipolar disorder. English-language literature published and cited in PubMed (MEDLINE) from January 1966 to December 2015 was searched with the keywords antipsychotic, atypical antipsychotic, or generic/brand name of atypical antipsychotics, and schizophrenia, bipolar disorder, bipolar mania, or bipolar depression, and safety, tolerability, weight gain, and randomized, placebo-controlled clinical trials. The absolute risk increases and the numbers needed to treat to harm (NNH) for ≥7% weight gain (objective) and self-report weight gain (subjective) were estimated. In schizophrenia, the NNH for 7% or greater weight gain ranged from 5 to 62, and the NNH for self-reported weight gain was from 11 to -224. The ratio of self-reported NNH to 7% or greater NNH was from 1.5 to 8.0. In bipolar mania, the NNH for 7% or greater weight gain ranged from 7 to -101 and the NNH for self-reported weight gain was from 13 to 84. The ratio of self-reported NNH to 7% or greater NNH was from 0.9 to 2.5. In bipolar depression, the NNH for 7% or greater weight gain ranged from 5 to 69, and the NNH for self-reported weight gain was from 8 to 17. The ratio of self-reported NNH to 7% or greater NNH was 1.2 to 1.6. Subjective reporting underestimated the risk of antipsychotic-related weight gain compared with objectively measured weight change. Self-awareness of antipsychotic-related weight gain was lower in patients with schizophrenia than in patients with bipolar disorder. Measuring weight change during antipsychotic treatment should be a routine practice.

Approximately one third of all deliveries in the United States are via cesarean. Previous research indicates weight gain during pregnancy is associated with an increased risk of cesarean delivery. It remains unclear, however, whether and to what degree weight gain between deliveries (ie, interdelivery weight gain) is associated with cesarean delivery in a subsequent pregnancy following a vaginal delivery. The objective of the study was to determine whether interdelivery weight gain is associated with an increased risk of intrapartum cesarean delivery following a vaginal delivery. This was a case-control study of women who had 2 consecutive singleton births of at least 36 weeks' gestation between 2005 and 2016, with a vaginal delivery in the index pregnancy. Women were excluded if they had a contraindication to a trial of labor (eg, fetal malpresentation or placenta previa) in the subsequent pregnancy. Maternal characteristics and delivery outcomes for both pregnancies were abstracted from the medical record. Maternal weight gain between deliveries was measured as the change in body mass index at delivery. Women who underwent a subsequent cesarean delivery were compared with those who had a repeat vaginal delivery using χ2 statistics for categorical variables and Student t tests or analysis of variance for continuous variables. Multivariable logistic regression was used to determine whether interdelivery weight gain remained independently associated with intrapartum cesarean delivery after adjusting for potential confounders. Of 10,396 women who met eligibility criteria and had complete data, 218 (2.1%) had a cesarean delivery in the subsequent pregnancy. Interdelivery weight gain was significantly associated with cesarean delivery and remained significant in multivariable analysis for women with a body mass index increase of at least 2 kg/m2 (adjusted odds ratio, 1.53, 95% confidence interval, 1.03-2.27 for a body mass index increase of 2 kg/m2 to women who gained

The obesity-asthma phenotype has become an increasingly common situation in our clinical practice. The mechanisms behind poor asthma control in subjects who are obese remain unclear. We aimed to determine the effect of obesity on asthma control in a group of adult patients Method: Subjects who had been diagnosed as having asthma and who were admitted to our clinic were included to this study. Body mass index (BMI) and asthma control status of the patients were evaluated. BMI values at the time of diagnosis were also collected from the patient files, and the difference between basal and current BMI values were calculated. The effect of obesity and weight gain on asthma control was investigated. The study population was composed of 218 patients (29 men, 189 women), with a mean (standard deviation) age of 52.01 ± 11.6 years. Fifty-four percent of the patients were obese, 27.5% were overweight, and 18.3% were of normal weight. The baseline and current BMI values were higher in women than in the men. BMI increased with the increase in age or disease duration. Asthma control was poor in the patients who were obese and overweight despite optimal treatment. Moreover, asthma control was worse in patients who gained weight during the follow-up period. In our study, we found a significant relationship between obesity and asthma control. In addition, weight gain and being nonatopic also was found to worsen asthma control. In light of our finding that weight gain led to a decrease in asthma control, we suggest that weight loss may improve the course of asthma.

High body mass index (BMI) measured in middle age or later is an established risk factor for endometrial cancer. However, whether BMI measured in early adulthood and adult weight change are associated with endometrial cancer risk is less clear, particularly among nonusers of postmenopausal hormones (PMH). These associations were investigated among women in the Cancer Prevention Study II Nutrition Cohort. Women taking PMH (n = 11,624, 12 % of all women) were excluded, and the analysis was limited to 33,057 postmenopausal women who did not take PMH. Between enrollment in 1992/1993 and 30 June 2009, 447 women were diagnosed with endometrial cancer. Cox proportional hazards regression was used to calculate hazard rate ratios (RR) and corresponding 95 % confidence intervals (CI) for the association of BMI at age 18, calculated from recalled weight, and weight change between age 18 and 1992, with endometrial cancer incidence. BMI at age 18 was associated with higher risk of endometrial cancer in multivariable models adjusted for other risk factors (RR 1.29, 95 % CI 1.12-1.49 per 5 BMI units). Similarly, adult weight change was associated with higher risk of endometrial cancer (RR 1.81, 95 % CI 1.66-1.98 per 5 BMI unit change) in multivariable models adjusted for other risk factors. High BMI at age 18 and greater adult weight gain were strongly associated with risk of endometrial cancer. These results underscore the importance of both avoiding overweight/obesity in young adulthood and preventing weight gain thereafter to minimize risk of this cancer.

There is ample and growing evidence that obesity increases the risk of asthma and morbidity from asthma. Here, we review recent clinical evidence supporting a causal link between obesity and asthma, and the mechanisms that may lead to 'obese asthma'. Although in some children obesity and asthma simply co-occur, those with 'obese asthma' have increased asthma severity, lower quality of life, and reduced medication response. Underlying mechanistic pathways may include anatomical changes of the airways such as obstruction and dysanapsis, systemic inflammation, production of adipokines, impaired glucose-insulin metabolism, altered nutrient levels, genetic and epigenetic changes, and alterations in the airway and/or gut microbiome. A few small studies have shown that weight loss interventions may lead to improvements in asthma outcomes, but thus far research on therapeutic interventions for these children has been limited. Obesity increases the risk of asthma - and worsens asthma severity or control - via multiple mechanisms. 'Obese asthma' is a complex, multifactorial phenotype in children. Obesity and its complications must be managed as part of the treatment of asthma in obese children.

Objectives We hypothesized that shorter sleep durations and greater variability in sleep patterns are associated with weight gain in the first semester of university. Methods Students (N=132) completed daily sleep diaries for 9-weeks, completed the MEQ (chronotype) and CES-D (depressed mood) at week9, and self-reported weight/height (weeks 1&9). Mean and variability scores were calculated for sleep duration (TST,TSTv), bedtime (BT,BTv), and wake time (WT,WTv). Results An initial hierarchical regression evaluated (block1) sex, ethnicity; (block2) depressed mood, chronotype; (block3) TST; (block4) BT, WT; and (block5; R2change=0.09, p=0.005) TSTv, BTv, WTv with weight change. A sex-by-TSTv interaction was found. A final model showed that ethnicity, TST, TSTv, and BTv accounted for 31% of the variance in weight change for males; TSTv was the most significant contributor (R2 change=0.21, psleep duration contributes to males’ weight gain. Further investigation needs to examine sex-specific outcomes for sleep and weight. PMID:25115969

Interpersonal psychotherapy (IPT) prevents weight gain in adults with obesity and binge-eating-disorder, and is especially effective among those with increased psychosocial problems. However, IPT was not superior to health education (HE) to prevent excess weight gain at 1-year follow-up in 113 adolescent girls at high-risk for excess weight gain because of loss-of-control eating and high body mass index (BMI; kg/m2; Tanofsky-Kraff et al., 2014). Participants from the original trial were recontacted 3 years later for assessment. At baseline, adolescent- and parent-reported social-adjustment problems and trait anxiety were evaluated. At baseline and follow-ups, BMIz and adiposity by dual-energy x-ray absorptiometry were obtained. Nearly 60% were reassessed at 3 years, with no group differences in participation (ps ≥ .70). Consistent with 1 year, there was no main effect of group on change in BMIz/adiposity (ps ≥ .18). In exploratory analyses, baseline social-adjustment problems and trait-anxiety moderated outcome (ps social-adjustment problems or anxiety, IPT, compared to HE, was associated with the steepest declines in BMIz (p anxiety in HE and girls with low anxiety in IPT experienced gains (ps ≤ .03), while girls in IPT with high anxiety stabilized. Parent-reports yielded complementary findings. In obesity-prone adolescent girls, IPT was not superior to HE in preventing excess weight gain at 3 years. Consistent with theory, exploratory analyses suggested that IPT was associated with improvements in BMIz over 3 years among youth with high social-adjustment problems or trait anxiety. Future studies should test the efficacy of IPT for obesity prevention among at-risk girls with social-adjustment problems and/or anxiety. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Smoking cessation has been reported to be associated with high total gestational weight gain (GWG), which itself is a risk factor for adverse maternal-infant outcomes. Recent studies have criticized conventional single measures of GWG, since they may lead to biased results. Therefore, we aimed to compare patterns of GWG based on serial antenatal weight measurements between women who: never smoked, quit during pregnancy, continued to smoke. Participants (N = 509) of our longitudinal study were recruited from seven antenatal clinics in Southwestern Ontario. Serial GWG measurements were abstracted from medical charts, while information on smoking status was obtained from a self-administered questionnaire at a median gestational age of 32 (27-37) weeks. GWG patterns were assessed by fitting piecewise mixed-effects models. First trimester weight gains and weekly rates for the last two trimesters were compared by smoking status. During the first trimester, women who never smoked and those who quit during pregnancy gained on average 1.7 kg (95 % CI: 1.4-2.1) and 1.2 kg (0.3-2.1), respectively, whereas women who continued smoking gained more than twice as much (3.5 kg, 2.4-4.6). Weekly rate of gain in the second and third trimesters was highest in women who quit smoking (0.60 kg/week, 0.54-0.65), approximately 20 and 50 % higher than in women who never smoked and those who smoked during pregnancy, respectively. In this longitudinal study to examine GWG by smoking status based on serial GWG measurements, we found that women who quit smoking experienced a rapid rate of gain during the last two trimesters, suggesting that this high-risk group may benefit from targeted interventions.
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 conduct a systematic review assessing the effects of weight gain on the incidence of periodontitis in adults. Electronic searches in four databases were performed up to and including February 2015. Only prospective longitudinal studies assessing the association between weight gain and the incidence of periodontitis in adults were eligible to be included in this study. All studies should state a clear description of nutritional status (Body Mass Index; Waist Circumference) as well as the case definition of periodontitis. Pooled relative risks (RR) for becoming overweight and obese on the incidence of periodontitis were estimated by meta-analysis. Quality was assessed with the Newcastle-Ottawa scale for cohort studies. Five articles were included in this review and meta-analysis with 42,198 subjects enrolled. Subjects who became overweight and obese presented higher risk to develop new cases of periodontitis (RR 1.13; 95%CI 1.06-1.20 and RR 1.33 95%CI 1.21-1.47 respectively) compared with counterparts who stayed in normal weight. A clear positive association between weight gain and new cases of periodontitis was found. However, these results are originated from limited evidence. Thus, more studies with longitudinal prospective design are needed. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Obesity and poor sleep are highly prevalent among Black women. We examined whether a weight gain prevention intervention improved sleep among Black women. We conducted a randomized trial comparing a 12-month weight gain prevention intervention that included self-monitoring through mobile technologies and phone coaching to usual care in community health centers. We measured sleep using the Medical Outcomes Study Sleep Scale at baseline, 12 months, and 18 months. The scale examines quantity of sleep, sleep disturbance, sleep adequacy, daytime somnolence, snoring, shortness of breath, and global sleep problems (sleep problem indices I and II). Participants (n = 184) were on average 35.4 years and obese (BMI 30.2 kg/m2); 74% made sleep duration was 6.4 (1.5) hours. Controlling for weight change and sleep medication, the intervention group reported greater improvements in sleep disturbance [-8.35 (-16.24, -0.45)] and sleep problems at 12 months: sleep problem index I [-8.35 (-16.24, -0.45)]; sleep problem index II [-8.35 (-16.24, -0.45)]. However, these findings did not persist at 18 months. Preventing weight gain may afford clinical benefit on improving sleep quality. The trial was registered with the ClinicalTrials.gov database (NCT00938535).

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.

To identify risk factors for adverse pregnancy outcome in women with inflammatory bowel disease (IBD) and to assess the effect of maternal pre-pregnancy weight and weight gain during pregnancy on pregnancy outcome. A retrospective, matched control study of all gravid women with IBD treated in a single tertiary center. Data were compared with healthy controls matched to by age, parity and pre-pregnancy BMI in a 3:1 ratio. Overall, 300 women were enrolled, 75 women in the study group (28 with ulcerative colitis and 47 with Crohn's disease) and 225 in the control group. The rates of preterm delivery and small for gestational age were higher in the study group (13.3 vs. 5.3% p = 0.02 and 6.7 vs. 0.9%, p = 0.004). The rate of cesarean section (36 vs. 19.1%; p = 0.002), NICU admission (10.7 vs. 4.0%, p = 0.03) and low 5-Min Apgar (4.0 vs. 0.4%, p = 0.02) were increased in the study group. Disease activity within 3 months of conception [OR 8.4 (1.3-16.3)] and maternal weight gain of less than 12 kg. [OR 3.6 (1.1-12.2)] were associated with adverse pregnancy outcome. Active disease at conception and inappropriate weight gain during pregnancy are associated with increased adverse pregnancy outcome in patients with IBD.

To investigate how the 2009 Institute of Medicine (IOM) guidelines for pregnancy weight gain for obese women relate to the longer-term outcome of childhood obesity. Maternal, neonatal, soioeconomic, and nutritional histories were collected for mothers with children age 2-5 years old. Women in each body mass index (BMI) category were categorized based on under, appropriate (AG), and over weight gain per IOM guidelines and compared with rates of childhood obesity in each category. A total of 502 mother-child pairs were enrolled; 36.4% of women were obese at the start of pregnancy. Obese women who were AG by IOM guidelines were more likely than underweight, normal weight, and overweight women to have obese offspring (29.5% vs. 14.2%, p = 0.04). The BMI percentiles of the offspring of obese AG women were 10 percentile points higher than the 55th percentile of the other groups. The 2009 IOM pregnancy weight gain guidelines for obese women may still be too high when considering longer-term outcomes such as childhood obesity. Further studies are needed.

Childhood disadvantage has been associated with increased risk of obesity from childhood through adulthood and those who are disadvantaged across the lifecourse are at highest risk. The effect of lifecourse socioeconomic status (SES) is particularly important for Black women due to the higher prevalence of low SES and obesity in Black compared to White women. We assessed associations of lifecourse SES, as indicated by educational status, with adult weight in African American women. We assessed the associations of parental education, current education (education of participant or her spouse), and a combination of parental and current education (lifecourse education) with weight gain among 21,457 women aged education compared to the highest level (college graduate). The age- and height-adjusted differences in mean weight gain for the lowest levels of parental and current education compared to the highest levels were 3.29 and 4.49 kg, respectively. The age-adjusted risk ratios for obesity for the lowest level of parental and current education were 1.44 (95% CI 1.32-1.57) and 1.75 (95% CI 1.57-1.95), respectively. Risk of obesity was lowest among those with current education of college graduate, regardless of parental education. Educational level of college graduate may overcome the adverse effects of low parental education on weight gain and obesity risk.

Adverse pregnancy outcomes, including maternal and neonatal outcomes of women with inappropriate GWG, including underweight and overweight, were studied and compared with those of women with appropriate GWG.Results: Complete data of 1,943 women were obtained. Among these women, the mean age was 17.4±1.4 years and mean body mass index at first visit was 19.1±3.0 kg/m2. The prevalence of inappropriate GWG was 61.7%. Underweight women were more likely to experience anemia and preterm delivery, whereas overweight women required more cesarean sections because of cephalopelvic disproportion and preeclampsia, compared to women with appropriate weight gain (all P<0.001. The rates of gestational diabetes mellitus among women who were underweight, overweight, or appropriate weight were not significantly different.Conclusion: More than 60% of teenage pregnancies showed inappropriate GWG. GWG had a significant impact on pregnancy outcomes. Keywords: prevalence, pregnancy outcome, inappropriate gestational weight gain, teenage pregnancy

Full Text Available The aim of the present study was to evaluate the influence of age and genetics in dairy heifers on resistance to the cattle tick Rhipicephalus (Boophilus microplus and correlate these parameters with weight gain. Twenty-two heifers were evaluated from birth up to two years of age. Resistance to the cattle tick was evaluated by counting the number of engorged female ticks and subjective qualification of the larvae and nymph infestation. The animals were weighted in the first 24 hours after birth and at six, 12, 18 and 24 months of age. The average tick count and weight gain were compared by Tukey’s test at 5% significance. Subsequently, linear regression was performed to verify the strength of the association between the risk factors age and genetics and infestation by R. (B. microplus. Age and genetics were both significant risk factors for R. (B. microplus infestation in heifers. Between the third and sixth months of age, the animals showed a window of susceptibility to R.

To prospectively examine the extent to which mealtime habits influences the risk of weight gain and obesity in Mexican adults. We performed a prospective cohort study. The Mealtime Habits Quality (MHQ) scale was used for assessing participants' MHQ; the outcomes of interest were gain ≥5 % of body weight, developing overweight/obesity and abdominal obesity, after 7 years of follow-up. In order to estimate the independent effect of MHQ on anthropometric indicators, generalized linear models were computed to obtain adjusted relative risks (95 % CI). The state of Morelos, Mexico.

Compared with participants classified in the higher MHQ category, individuals in the middle and lower MHQ groups had a 4·1 (2·5, 6·7) and 6·2 (3·9, 9·7) fold greater risk of gain ≥5 % of body weight, respectively; 6·6 (2·8, 15·5) and 8·6 (3·7, 19·8) fold greater risk of becoming overweight/obese, respectively; and 3·8 (2·0, 7·3) and 5·3 (2·8, 9·8) fold greater risk of developing abdominal obesity, respectively. This study provides evidence about the influence of a set of mealtime habits on obesity indicators, showing that greater adherence to unadvisable mealtime habits increases the risk of developing unhealthy anthropometric indicators. Since the meal is one of the most important sources of food intake, and consequently weight status, the MHQ scale can be a useful population tool to predict weight gain and obesity.

Objectives Childhood disadvantage has been associated with increased risk of obesity from childhood through adulthood and those who are disadvantaged across the lifecourse are at highest risk. The effect of lifecourse socioeconomic status (SES) is particularly important for black women due to the higher prevalence of low SES and obesity in black compared to white women. We assessed associations of lifecourse SES, as indicated by educational status, with adult weight in African American women. Design We assessed the associations of parental education, current education (education of participant or her spouse), and a combination of parental and current education (lifecourse education) with weight gain among 21,457 women aged less than age 55 in the longitudinal Black Women’s Health Study which began in 1995. Main Outcome Measures We estimated the mean difference in weight gain between age 18 and age in 2009, and risk ratios for obesity in 2009, in each level of education compared to the highest level (college graduate). Results The age- and height-adjusted differences in mean weight gain for the lowest levels of parental and current education compared to the highest levels were 3.29 and 4.49 kg, respectively. The age-adjusted risk ratios for obesity for the lowest level of parental and current education were 1.44 (95% CI 1.32-1.57) and 1.75 (95% CI 1.57-1.95), respectively. Risk of obesity for was lowest among those with current education of college graduate, regardless of parental education. Conclusions Educational level of college graduate may overcome the adverse effects of low parental education on weight gain and obesity risk. PMID:22764643

The objective of this study is to gain an in-depth understanding of issues related to gestational weight gain (GWG) including general health, diet, and physical activity among high and low income women and to elucidate socio-ecological and psychosocial risk factors that increase risk for excessive GWG. We conducted 9 focus groups with high (n = 4 groups) and low (n = 5 groups) income pregnant women aged 18-35 years to discuss health, GWG, diet and physical activity following a discussion guide. The constant comparative method was used to code focus group notes and to identify emergent themes. Themes were categorized within the integrative model of behavioral prediction. Low income women, in contrast to high income women, had higher BMIs, had more children, and were African American. Diet and physical activity behaviors reported by low income women were more likely to promote positive energy balance than were those of high income women. The underlying behavioral, efficacy, and normative beliefs described by both groups of women explained most of these behaviors. Experiencing multiple risk factors may lead to (1) engaging in several behavior changes during pregnancy unrelated to weight and (2) holding more weight gain-promoting beliefs than weight maintaining beliefs. These factors could inhibit diet and physical activity behaviors and/or behavior changes that promote energy balance and in combination, result in excessive GWG. Low income women experience multiple risk factors for excessive GWG and successful interventions to prevent excessive GWG and pregnancy related weight gain will need to recognize the complex web of influences.
Full Text Available The FTO gene, located on chromosome 16q12.2, and the MAF gene, located on chromosome 16q22-23, were identified as genes harboring common variants with an impact on obesity predisposition. We studied the association of common variants with birth weight, gain of body weight, body mass index (BMI, Ponderal index and relevant neonatal outcomes in a large German cohort of infants with a birth weight below 1500 grams.The single nucleotide polymorphisms rs9939609 (FTO gene and rs1424233 (MAF gene were genotyped using allelic discrimination assays in a prospective multicenter cohort study conducted in 15 neonatal intensive care units in Germany from September 2003 until January 2008. DNA samples were extracted from buccal swabs according to standard protocols.1946 infants were successfully genotyped at FTO and 2149 infants at MAF. Allele frequencies were not significantly different from other European cohorts. The polymorphisms were in Hardy-Weinberg equilibrium. The polymorphisms did not show associations with birth weight, BMI and Ponderal Index at discharge, and weight gain, neither testing for a dominant, additive nor for a recessive model.Since an association of the polymorphisms with weight gain has been demonstrated in multiple populations, the lack of association in a population of preterm infants with regular tube feeding after birth and highly controlled feeding volumes provides evidence for the hypothesis that these polymorphisms affect food intake behavior and hunger rather than metabolism and energy consumption.

Excess weight gain affects nearly half of all pregnancies in the United States and is a strong risk factor for adverse maternal and fetal outcomes, including long-term obesity. The Internet is a prominent source of information during pregnancy; however, the accuracy of this online information is unknown. To identify, characterize, and assess the accuracy of frequently accessed webpages containing information about weight gain during pregnancy. A descriptive study was used to identify and search frequently used phrases related to weight gain during pregnancy on the Google search engine. The first 10 webpages of each query were characterized by type and then assessed for accuracy and completeness, as compared to Institute of Medicine guidelines, using crowdsourcing. A total of 114 queries were searched, yielding 305 unique webpages. Of these webpages, 181 (59.3%) included information regarding weight gain during pregnancy. Out of 181 webpages, 62 (34.3%) contained no specific recommendations, 48 (26.5%) contained accurate but incomplete recommendations, 41 (22.7%) contained complete and accurate recommendations, and 22 (12.2%) were inaccurate. Webpages were most commonly from for-profit websites (112/181, 61.9%), followed by government (19/181, 10.5%), medical organizations or associations (13/181, 7.2%), and news sites (12/181, 6.6%). The largest proportion of for-profit sites contained no specific recommendations (44/112, 39.3%). Among pages that provided inaccurate information (22/181, 12.2%), 68% (15/22) were from for-profit sites. For-profit websites dominate the online space with regard to weight gain during pregnancy and largely contain incomplete, inaccurate, or no specific recommendations. This represents a significant information gap regarding an important risk factor for obesity among mothers and infants. Our findings suggest that greater clinical and public health efforts to disseminate accurate information regarding healthy weight gain during pregnancy

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.
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. Key features included

Weight gain has been reported after deep brain stimulation of the subthalamic nucleus (STN-DBS), a widely used treatment for Parkinson's disease (PD). This nucleus has been repeatedly found to be linked both to reward and to inhibitory control, two key aspects in the control of food intake. In this study, we assessed whether weight gain experienced by patients with PD after STN-DBS, might be due to an alteration of reward and inhibitory functions. Eighteen patients with PD were compared to eighteen healthy controls and tested three times: before surgery, in ON medication and after surgery, respectively five days after the implantation in ON medication/OFF stimulation and at least three months after surgery in ON medication/ON stimulation. All participants were assessed for depression (Beck Depression Inventory), anhedonia (Snaith-Hamilton Pleasure Scale) and impulsiveness (Barratt Impulsiveness Scale). They performed a battery of tests assessing food reward sensitivity (Liking, Wanting and Preference) and a food go/no-go task. Results showed that body weight significantly increased after STN-DBS. A few days after surgery, patients were slower and more impulsive in the go/no-go task, showed a higher preference for high calorie (HC) foods and rated foods as less tasty. Months after subthalamic stimulation, the performance on the go/no-go task improved while no differences were observed in reward sensitivity. Interestingly, weight gain resulted greater in patients with higher levels of attentional impulsiveness pre-surgery, higher wanting for low calorie (LC) foods and impulsivity in the go/no-go task in ON medication/ON stimulation. However, only wanting and attentional impulsivity significantly predicted weight change. Furthermore, weight gain resulted associated with the reduction of l-Dopa after surgery and disease's duration. In conclusion, our findings are consistent with the view that weight gain in PD after STN-DBS has a multifactorial nature, which reflects

To study the influence of maternal socioeconomic and emotional factors on infant weight gain and weight faltering (failure to thrive) in the first year of life. The Gateshead Millennium Baby Study is a population birth cohort in northeast England studied prospectively from birth, via parental questionnaires and a health check aged 13 months. Data were collected on maternal education, deprivation, eating attitudes, and depression, using the Edinburgh Post Natal Depression Scale (EPDS) at 3 months. Weight gain was assessed using change in weight SD score, conditional on birth weight (Thrive Index); weight faltering was defined as conditional weight gain below the 5th centile. Of 923 eligible infants born at term, 774 (84%) had both weight and questionnaire data. Replicating a previous finding, both the highest and the lowest levels of deprivation were associated with weight faltering; this was independent of the type of milk feeding. No relation was found with maternal educational status. Maternal eating restraint was unrelated to weight gain. Infants of mothers with high depression symptom scores (EPDS >12) had significantly slower weight gain and increased rates of weight faltering up to 4 months (relative risk 2.5), especially if they came from deprived families, but by 12 months they were no different from the remainder of the cohort. In this setting, social and maternal characteristics had little influence on infants' weight gain, apart from a strong, but transient effect of postnatal depression.

Obesity is a major health problem in the United States and a growing concern among members of the military. Posttraumatic stress disorder (PTSD) has been associated with overweight and obesity and may increase the risk of those conditions among military service members. Disordered eating behaviors have also been associated with PTSD and weight gain. However, eating disorders remain understudied in military samples. We investigated longitudinal associations among PTSD, disordered eating, and weight gain in the Millennium Cohort Study, which includes a nationally representative sample of male (n = 27,741) and female (n = 6,196) service members. PTSD at baseline (time 1; 2001-2003) was associated with disordered eating behaviors at time 2 (2004-2006), as well as weight change from time 2 to time 3 (2007-2008). Structural equation modeling results revealed that the association between PTSD and weight change from time 2 to time 3 was mediated by disordered eating symptoms. The association between PTSD and weight gain resulting from compensatory behaviors (vomiting, laxative use, fasting, overexercise) was significant for white participants only and for men but not women. PTSD was both directly and indirectly (through disordered eating) associated with weight change. These results highlight potentially important demographic differences in these associations and emphasize the need for further investigation of eating disorders in military service members.

to explore gestational weight gain in healthy women in relation to pre-pregnancy Body Mass Index, diet and physical activity. a cross-sectional survey was conducted among 455 healthy pregnant women of all gestational ages receiving antenatal care from an independent midwife in the Netherlands. Weight gain was assessed using the Institute of Medicine (IOM) guidelines and classified as below, within, or above the guidelines. A multinomial regression analysis was performed with weight gain classifications as the dependent variable (within IOM-guidelines as reference). Independent variables were pre-pregnancy Body Mass Index, diet (broken down into consumption of vegetables, fruit and fish) and physical activity (motivation to engage in physical activity, pre-pregnancy physical activity and decline in physical activity during pregnancy). Covariates were age, gestational age, parity, ethnicity, family income, education, perceived sleep deprivation, satisfaction with pre-pregnancy weight, estimated prepregnancy body mass index, smoking, having a weight gain goal and having received weight gain advice from the midwife. forty-two per cent of the women surveyed gained weight within the guidelines. Fourteen per cent of the women gained weight below the guidelines and 44 per cent gained weight above the guidelines. Weight gain within the guidelines, compared to both above and below the guidelines, was not associated with pre-pregnancy Body Mass Index nor with diet. A decline in physical activity was associated with weight gain above the guidelines (OR 0.54, 95 per cent CI 0.33-0.89). Weight gain below the guidelines was seen more often in women who perceived a greater sleep deprivation (OR 1.20, 95 per cent CI 1.02-1.41). Weight gain above the guidelines was seen less often in Caucasian women in comparison to non-Caucasian women (OR 0.22, 95 per cent CI 0.08-0.56) and with women who did not stop smoking during pregnancy (OR 0.49, 95 per cent CI 0.25-0.95). a decline in

Prenatal air pollution exposure inhibits fetal growth, but implications for postnatal growth are unknown. We assessed weights and lengths of US infants in the Project Viva cohort at birth and 6 months. We estimated 3rd-trimester residential air pollution exposures using spatiotemporal models. We estimated neighborhood traffic density and roadway proximity at birth address using geographic information systems. We performed linear and logistic regression adjusted for sociodemographic variables, fetal growth, and gestational age at birth. Mean birth weight-for-gestational age z-score (fetal growth) was 0.17 (standard deviation [SD] = 0.97; n = 2,114), 0- to 6-month weight-for-length gain was 0.23 z-units (SD = 1.11; n = 689), and 17% had weight-for-length ≥95th percentile at 6 months of age. Infants exposed to the highest (vs. lowest) quartile of neighborhood traffic density had lower fetal growth (-0.13 units [95% confidence interval (CI) = -0.25 to -0.01]), more rapid 0- to 6-month weight-for-length gain (0.25 units [95% CI = 0.01 to 0.49]), and higher odds of weight-for-length ≥95th percentile at 6 months (1.84 [95% CI = 1.11 to 3.05]). Neighborhood traffic density was additionally associated with an infant being in both the lowest quartile of fetal growth and the highest quartile of 0- to 6-month weight-for-length gain (Q4 vs. Q1, odds ratio = 3.01 [95% CI = 1.08 to 8.44]). Roadway proximity and 3rd-trimester black carbon exposure were similarly associated with growth outcomes. For 3rd-trimester particulate matter (PM2.5), effect estimates were in the same direction, but smaller and imprecise. Infants exposed to higher traffic-related pollution in early life may exhibit more rapid postnatal weight gain in addition to reduced fetal growth.

Specific dietary and other lifestyle behaviors may affect the success of the straightforward-sounding strategy "eat less and exercise more" for preventing long-term weight gain. We performed prospective investigations involving three separate cohorts that included 120,877 U.S. women and men who were free of chronic diseases and not obese at baseline, with follow-up periods from 1986 to 2006, 1991 to 2003, and 1986 to 2006. The relationships between changes in lifestyle factors and weight change were evaluated at 4-year intervals, with multivariable adjustments made for age, baseline body-mass index for each period, and all lifestyle factors simultaneously. Cohort-specific and sex-specific results were similar and were pooled with the use of an inverse-variance-weighted meta-analysis. Within each 4-year period, participants gained an average of 3.35 lb (5th to 95th percentile, -4.1 to 12.4). On the basis of increased daily servings of individual dietary components, 4-year weight change was most strongly associated with the intake of potato chips (1.69 lb), potatoes (1.28 lb), sugar-sweetened beverages (1.00 lb), unprocessed red meats (0.95 lb), and processed meats (0.93 lb) and was inversely associated with the intake of vegetables (-0.22 lb), whole grains (-0.37 lb), fruits (-0.49 lb), nuts (-0.57 lb), and yogurt (-0.82 lb) (P≤0.005 for each comparison). Aggregate dietary changes were associated with substantial differences in weight change (3.93 lb across quintiles of dietary change). Other lifestyle factors were also independently associated with weight change (Psleep (more weight gain with 8 hours of sleep), and television watching (0.31 lb per hour per day). Specific dietary and lifestyle factors are independently associated with long-term weight gain, with a substantial aggregate effect and implications for strategies to prevent obesity.

In Experiment 1, food deprivation resulting in a 30% reduction in body weight produced significant increases in wheel running in both obese and lean female Zucker rats. In Experiment 2, a new technique, food contingent activity (FR, VI), dramatically increased wheel running in both obese and lean female Zucker rats. This increase in activity was achieved primarily during the dark period. Regardless of changes in activity levels, food intake and body weight gain remained similar to controls. When food was again available ad lib, activity levels rapidly decreased for obese but not lean rats. These results indicate that behavioral interventions alone are not sufficient to correct the obesity of the genetically obese rat.

Excessive weight gain during pregnancy and subsequent postpartum weight retention may contribute to the epidemic of obesity among women of childbearing age. Preventing excessive gestational weight gain (GWG) to optimize maternal, fetal and infant wellbeing is therefore of great importance. A number...... of dietary interventions in this area has been conducted with inconsistent results, which has made it difficult to identify effective strategies to prevent excessive weight gain during pregnancy among normal weight, overweight and obese women. The primary objective of this review was to evaluate the effect...

Evaluation of the relationship between canine weight gain from 6 to 15 weeks of age and passive coxofemoral joint (CFJ) laxity at 16 weeks of age. Longitudinal cohort study. Full- or half-sibling hounds (n = 56). Hounds were weighed weekly from 6 to 15 weeks of age. Individual average daily gain (ADG) was calculated for each week (weekly) and for the study (overall). PennHIP distraction index (DI) was determined for each CFJ at 16 weeks. Mixed effects linear models were evaluated for associations of DI (highest and mean) with 15-week weight and ADGs (actual or normalized). Left and right DIs were compared with a Student's paired t-test. Significance was set at Pjoint laxity. Based on our results, ad libitum feeding between 6 and 15 weeks of age does not appear to have an adverse impact on joint laxity at 16 weeks of age as measured by the PennHIP DI.

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. (c) 2009 Movement Disorder Society.

Obesity is one of the most common chronic conditions in the world. Its management is difficult, partly due to the multiple associated comorbidities including fatty liver, diabetes, hypertension, and hyperlipidemia. As a result, the choice of prescription medications in overweight and obese patients has important implications as some of them can actually worsen the fat accumulation and its associated metabolic complications. Several prescription medications are associated with weight gain with mechanisms that are often poorly understood and under-recognized. Even less data are available on the distribution of fat and lipotoxicity (the organ damage related to fat accumulation). The present review will discuss the drugs associated with weight gain, their mechanism of action, and the magnitude and timing of their effect.

This study aimed to improve understanding of obesity in prison by investigating prison nurses' perceptions of weight gain and obesity. In-depth semistructured interviews were carried out with 17 nurses who worked in two male prisons in the United Kingdom. Nurses identified a variety of factors that they believed contributed to obesity and weight gain in the prison setting. These included factors caused by prisoner behavior, such as poor food choices and sedentary lifestyle. Factors influenced by the prison environment, such as stress of imprisonment, prison regime, and prison culture, were also seen as significant. These factors were seen as barriers to the role of nurses delivering care in prison. Nurses explained how they adapted their role to overcome these barriers.

To investigate how extracorporal cholesterol lowering therapy affects circulating leptin levels in patients with ravenous hunger after treatment and permanent weight gain. A case report. 51 y old caucasian male patient with moderate chronic renal failure. Serum Leptin concentration (RIA, Linco Research Inc, St. Louis, MO, USA), total cholesterol, low density lipoprotein cholesterol, blood glucose levels, calorie intake by food records. During treatment total cholesterol was reduced by 50%. Serum Leptin levels showed a 42% reduction at the end of treatment, that by far exceeds the physiological diurnal variation. Calorie intake was significantly increased on days of treatment. We conclude that this artificial reduction in circulating leptin plays an important role in the pathogenesis of ravenous hunger and weight gain under extracorporal cholesterol lowering therapy in this case.

Adult male and female rats were housed in a sedentary condition or given free access to a running wheel for 50 days. Running wheel activity of female rats was higher than that of males throughout the experiment. Food intake, of both male and female rats that could take exercise increased, and the rate of increase of females was greater than that of males. In both males and females there was a positive correlation between food intake and running wheel activity. These findings suggest that the sex difference in the rate of increase in food intake elicited by wheel running is at least partly explained by the sex difference in running wheel activity. Although food intake increased as a function of running wheel activity, the weight gains of both sexes were slower than those of sedentary rats. In both sexes this slower weight gain was mainly due to less accumulation of fat.

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.
Full Text Available Purpose: Targeting the problem of overload trucking in Highway Transportation of iron ore from Caofeidian to Tangshan (HTCT, this paper aims to assess long-term effects of alternative Truck Weight Regulation (TWR policies on sustainability of HTCT. Design/methodology/approach: A system dynamics model was established for policy evaluation. The model, composed of six interrelating modules, is able to simulate policies effects on trucking issues such as freight flow, truck traffic flow, pavement performance, highway transport capacity and trucking time, and further on the Cumulative Economic Cost (CEC including transport cost and time cost of freight owners and the Cumulative Social Cost (CSC including pavement maintenance cost, green house gas emission cost, air pollutants emission cost and traffic accidents cost, so the effects of TWR policies on sustainability of HTCT could be evaluated. Findings: According to different values of overload ratio which a TWR policy allows, alternative TWR policies are classified into three types, which are The Rigid Policy (TRP, The Moderate Policy (TMP and The Tolerant Policy (TTP. Results show that the best policy for sustainability of HTCT depends on the importance of CSC which is expected by the local government. To be specific, (1 if CSC is considered much less important than CEC, the local government should continue implementing the current TTP with the maximum overload ratio; (2 if CSC is considered much more important than CEC, then TRP is recommended; and (3 if CSC is considered slightly more important than CES, TMP with overload ratio of 80% is the best. Practical implications: Conclusions of this paper may help the local government design appropriate TWR policies to achieve sustainability of HTCT. Originality/value: To the best of our knowledge, this is the first effort to evaluate TWR policies on sustainability of regional freight transportation based on system dynamics modeling.

To determine whether gestational weight gain (GWG) was associated with increased odds of childhood overweight after accounting for pre-pregnancy BMI. In a prospective cohort study based on a premarital and perinatal health care system in China, data of 100 612 mother-child pairs were obtained. The main exposure was GWG as both a continuous and categorical variable. The outcome measure was overweight, defined by age- and sex-specific cutoff values for body mass index (BMI) in children aged 3-6 years. A 1-kg increase in maternal GWG was associated with an increase of 0.009 (95% confidence interval [CI]: 0.007-0.010, P < 0.001) in children's mean BMI; in the subgroup of pre-pregnancy overweight/obese mothers, the increase in children's BMI was 0.028 (95% CI, 0.017-0.039, P < 0.001). Excessive GWG played an important role in childhood overweight when adequate GWG was used as the reference, with an odds ratio (OR) of 1.21 (95% CI, 1.12-1.29). The risk was highest (OR 2.22; 95% CI, 1.79-2.76) in the children of mothers who were overweight/obese before pregnancy and gained excessive weight during pregnancy. Greater maternal GWG was associated with greater offspring BMI, and the risk of overweight was doubled in children whose mothers were overweight/obese before pregnancy and gained excessive weight during pregnancy. As a result, maintenance of appropriate weight gain during pregnancy and prophylaxis of maternal overweight/obesity before pregnancy should be a strategy for preventing childhood overweight/obesity.

Objective Prenatal androgen exposure has been suggested to play a role in polycystic ovary syndrome. Given the limited information on what maternal characteristics influence maternal testosterone levels, and the even less explored routes by which female fetus androgen exposure would occur, the aim of this study was to investigate the impact of maternal age, BMI, weight gain, depressed mood and aromatase SNPs on testosterone levels in maternal serum and amniotic fluid of female fetuses.

. Generally, low GWG was advantageous for the mother, but it increased the risk of having a small baby, particularly for underweight women. CONCLUSIONS: Heavier women may benefit from avoiding high and very high GWG, which brings only a slight increase in the risk of growth restriction for the infant. High...... weight gain in underweight women does not appear to have deleterious consequences for them or their infants, but they may want to avoid low GWG to prevent having a small baby....

Obesity prevalence has shown a marked increase in recent years. Strategies designed to manage the trend are not always effective in the long term. This qualitative study investigated perceived causes of weight gain in a group of female slimmer's. Understanding beliefs about the causes of a problem can help explain behaviour and find solutions. It is therefore justified and timely to explore beliefs about causes of weight gain. A group of 11 (adult) slimmer's were interviewed using a semi-structured approach, and the data obtained were analysed thematically. Four main themes were identified; importance of habits, influence of learning early models about the world through food, eating beyond feeling full and use of food as therapy. Behavioural causes were given to explain weight gain, perceived to be mediated by modern lifestyles or changes in circumstances. In addition, beliefs about food and its function related to personal history or childhood experience, which subsequently were used negatively in adulthood. The potential contributions of these findings for practice are explored. © 2012 The Authors. Journal of Human Nutrition and Dietetics © 2012 The British Dietetic Association Ltd.

Full Text Available 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.

During recovery from social stress in a visible burrow system (VBS), during which a dominance hierarchy is formed among the males, rats display hyperphagia and gain weight preferentially as visceral adipose tissue. By proportionally increasing visceral adiposity, social stress may contribute to the establishment of metabolic disorder. Amylin was administered to rats fed ad libitum during recovery from VBS stress in an attempt to prevent hyperphagia and the resultant gain in body weight and fat mass. Amylin treatment reduced food intake, weight gain, and accumulation of fat mass in male burrow rats, but not in male controls that spent time housed with a single female rather than in the VBS. Amylin did not alter neuropeptide Y (NPY), agouti-related peptide (AgRP), or proopiomelanocortin (POMC) mRNA expression in the arcuate nucleus of the hypothalamus as measured at the end of the recovery period, nor did it affect plasma corticosterone or leptin. Amylin exerted most of its effect on food intake during the first few days of recovery, possibly through antagonism of NPY and/or increasing leptin sensitivity. The potential for chronic social stress to contribute to metabolic disorder is diminished by amylin treatment, though the neuroendocrine mechanisms behind this effect remain elusive. PMID:22832535

A prospective study of chronotype as a predictor of increased weight gain and body mass index (BMI) among college freshman was undertaken. At baseline, 137 college freshmen were characterized as morning, neutral, or evening types using the reduced version of the Morningness-Eveningness Questionnaire. Additionally, information was collected regarding weight, BMI, and health habits (e.g., junk food and alcohol consumption). These additional measures consisted of a descriptive questionnaire, the Pittsburgh Sleep Quality Index, the International Physical Activity Questionnaire, the Gray-Donald Eating Patterns Questionnaire, and the Positive and Negative Affect Scale. Participants included 79 females and 80 males with a mean age of 18.25 (SD=0.56) yrs. Eight weeks later, participants returned (N=54) to complete follow-up measures, which were identical to baseline assessments with the exception of the descriptive questionnaire, in which demographic questions were removed. Evening types had a significantly greater BMI gain (p<0.05) when compared with morning/neutral types. Health behaviors did not differ by chronotype. Future studies should seek to clarify the mechanisms underlying the chronotype-BMI/weight gain relationship. PMID:23688114

Short night-time sleep duration is a possible factor contributing to childhood obesity. Our objective was to evaluate associations between sleep timing (including bedtime and waketime) and weight gain in 4- to 5-year-old children. We used cross-sectional and longitudinal regression analyses of a large, nationally representative sample of children from the Early Childhood Longitudinal Study-Birth Cohort. Data regarding the timing and duration of weekday sleep were assessed via parent questionnaire. Short sleep duration, late bedtime and early waketime were defined as those greater than one standard deviation from the mean for the group. Using linear regression adjusted for confounders, sleep duration at 4 and 5 years and bedtime at 5 years were linked to body mass index (BMI) z-score (P sleeping sleep duration (P sleep durations and later bedtimes were more likely to be obese and to gain weight over time. Pediatricians should encourage families to place children to bed at earlier times to promote longer sleep duration as a potential means of controlling weight gain. © 2014 The Authors.

Gaining too much or too little weight in pregnancy (according to Institute of Medicine (IOM) guidelines) negatively affects both mother and child, but many women find it difficult to manage their gestational weight gain (GWG). Here we describe the use of the intervention mapping protocol to design 'Come On!', an intervention to promote adequate GWG among healthy pregnant women. We used the six steps of intervention mapping: (i) needs assessment; (ii) formulation of change objectives; (iii) selection of theory-based methods and practical strategies; (iv) development of the intervention programme; (v) development of an adoption and implementation plan; and (vi) development of an evaluation plan. A consortium of users and related professionals guided the process of development. As a result of the needs assessment, two goals for the intervention were formulated: (i) helping healthy pregnant women to stay within the IOM guidelines for GWG; and (ii) getting midwives to adequately support the efforts of healthy pregnant women to gain weight within the IOM guidelines. To reach these goals, change objectives and determinants influencing the change objectives were formulated. Theories used were the Transtheoretical Model, Social Cognitive Theory and the Elaboration Likelihood Model. Practical strategies to use the theories were the foundation for the development of 'Come On!', a comprehensive programme that included a tailored Internet programme for pregnant women, training for midwives, an information card for midwives, and a scheduled discussion between the midwife and the pregnant woman during pregnancy. The programme was pre-tested and evaluated in an effect study.

In 2010, the American Heart Association established the concept of ideal cardiovascular health. Nationally representative data estimated that Healthy Diet Score. In a cohort of young adults (N=196), we aimed to investigate the prevalence of ideal cardiovascular health and ideal Healthy Diet Score and its association to weight gain over a 4-year follow-up period. Anthropometric measures, blood pressure, and blood samples were taken according to standardized procedures. Dietary intake was measured by a 3-day food diary and verified by a registered dietitian. We observed that only 0.5% of our sample met the criteria for ideal cardiovascular health and only 4.1% met the criteria for an ideal Healthy Diet Score. The components of the Healthy Diet Score with the lowest observance were consumption of fruits and vegetables (9.7%) and whole grains (14.8%). Meeting zero or one out of five of the Healthy Diet Score components was associated with increased risk of weight gain over 4 years compared with meeting at least two components (P=0.03). With the exception of dietary criteria, prevalence was high for achieving ideal levels of the remaining six cardiovascular health metrics. In conclusion, in this sample of young adults, a very low prevalence of ideal overall cardiovascular health was observed, mainly driven by poor dietary habits, and a poor Healthy Diet Score was associated with increased weight gain.

The use of high fructose corn syrup (HFCS) has increased over the past several decades in the United States while overweight and obesity rates have risen dramatically. Some scientists hypothesize that HFCS consumption has uniquely contributed to the increasing mean body mass index (BMI) of the U.S. population. The Center for Food, Nutrition, and Agriculture Policy convened an expert panel to discuss the published scientific literature examining the relationship between consumption of HFCS or "soft drinks" (proxy for HFCS) and weight gain. The authors conducted original analysis to address certain gaps in the literature. Evidence from ecological studies linking HFCS consumption with rising BMI rates is unreliable. Evidence from epidemiologic studies and randomized controlled trials is inconclusive. Studies analyzing the differences between HFCS and sucrose consumption and their contributions to weight gain do not exist. HFCS and sucrose have similar monosaccharide compositions and sweetness values. The fructose:glucose (F:G) ratio in the U.S. food supply has not appreciably changed since the introduction of HFCS in the 1960s. It is unclear why HFCS would affect satiety or absorption and metabolism of fructose any differently than would sucrose. Based on the currently available evidence, the expert panel concluded that HFCS does not appear to contribute to overweight and obesity any differently than do other energy sources. Research recommendations were made to improve our understanding of the association of HFCS and weight gain.

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. 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. 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 olive oil, it is recommended that nurses use oil in infant massage in the neonatal units.

Fetuin inhibits insulin-induced insulin receptor (IR) autophosphorylation and tyrosine kinase activity in vitro, in intact cells, and in vivo. The fetuin gene (AHSG) is located on human chromosome 3q27, recently identified as a susceptibility locus for type 2 diabetes and the metabolic syndrome. Here, we explore insulin signaling, glucose homeostasis, and the effect of a high-fat diet on weight gain, body fat composition, and glucose disposal in mice carrying two null alleles for the gene encoding fetuin, Ahsg (B6, 129-Ahsg(tm1Mbl)). Fetuin knockout (KO) mice demonstrate increased basal and insulin-stimulated phosphorylation of IR and the downstream signaling molecules mitogen-activated protein kinase (MAPK) and Akt in liver and skeletal muscle. Glucose and insulin tolerance tests in fetuin KO mice indicate significantly enhanced glucose clearance and insulin sensitivity. Fetuin KO mice subjected to euglycemic-hyperinsulinemic clamp show augmented sensitivity to insulin, evidenced by increased glucose infusion rate (P = 0.077) and significantly increased skeletal muscle glycogen content (P < 0.05). When fed a high-fat diet, fetuin KO mice are resistant to weight gain, demonstrate significantly decreased body fat, and remain insulin sensitive. These data suggest that fetuin may play a significant role in regulating postprandial glucose disposal, insulin sensitivity, weight gain, and fat accumulation and may be a novel therapeutic target in the treatment of type 2 diabetes, obesity, and other insulin-resistant conditions.

This meta-analysis aimed to estimate the relation between excessive gestational weight gain and macrosomia. We performed a meta-analysis by searching PubMed, EMBASE and the Cochrane library for English-language literature from inception to 1 October 2014. Studies assessing the relationship between excessive gestational weight gain and macrosomia were included. Characteristics including study design, country, sample size, definition of macrosomia, adjusted odds ratios, CIs and adjustment factors were extracted independently by two reviewers. Summary odds ratios were calculated by using a random-effects model meta-analysis. 15 relevant articles were eligible for the meta-analysis. Incorporated by random-effect model before the heterogeneity tests, the value of OR was 2.35 (95 % CI: 1.95, 2.85). Stratified analysis showed no differences regarding different study design, definition of macrosomia and location of study. There was no indication of a publication bias either from the result of Egger's test (P = 0.572) or Begg's test (P = 0.572). Our meta-analysis indicated that excessive gestational weight gain might increase the risk of macrosomia.

Helicobacter suis is a zoonotically important bacterium, that has been associated with gastritis and ulcerative lesions of the pars oesophagea of the stomach in pigs. Its exact role in these pathologies, however, still remains controversial. Therefore, a total of 29 medicated early weaned piglets were inoculated intragastrically or orally, with a total of 2 × 10(9) viable H. suis bacteria and the effect on gastric pathology and weight gain was determined. Twenty-three medicated early weaned piglets were inoculated with a sterile culture medium and used as sham-inoculated controls. The animals were euthanized between 28 and 42 days after inoculation. Infected animals showed a more severe gastritis compared to the control group. There was also a significant reduction of approximately 60 g per day (10%) in weight gain in H. suis inoculated animals compared to the sham-inoculated control animals. In conclusion, this study demonstrates for the first time that a pure in vitro culture of H. suis not only causes gastritis but also a marked decrease of the daily weight gain in experimentally infected pigs.

Sociocultural pressure to be thin is commonly reported by adolescents; yet, to what extent such pressure is associated with weight gain has not been evaluated longitudinally. Examine whether pressure to be thin was positively associated with weight and fat gain in adolescents. Participants were 196 healthy adolescent (age 15 ± 1 years old) girls (65%) and boys of varying weights (BMI 25 ± 7 kg/m2 ) studied at baseline and 1-year follow-up. At baseline, adolescents and their mothers reported pressure to be thin by questionnaire. At baseline and follow-up, BMI was calculated, and fat mass was assessed with air displacement plethysmography. Multiple regression was used to examine associations between baseline pressure to be thin and 1-year changes in BMI and fat mass. Accounting for multiple covariates, including baseline BMI or fat, adolescent-reported pressure from parents and peers and mother-reported pressure toward their teen were associated with greater gains in either adolescent BMI or fat (ps effects (ps peer pressure to be thin were associated with increases in BMI and fat mass during adolescence, particularly in heavier adolescents. Further research is necessary to clarify how this association operates reciprocally and to identify underlying explanatory mechanisms. © 2016 World Obesity Federation.

Based on clinical and animal studies, this review suggests a tri-phasic effect of second-generation antipsychotics (SGAs) on circulating ghrelin levels: an initial increase exerted by the acute effect of SGAs; followed by a secondary decrease possibly due to the negative feedback from the SGA-induced body weight gain or hyperphagia; and a final re-increase to reach the new equilibrium. Moreover, the results can also vary depending on individual SGAs, other hormonal states, dietary choices, and other confounding factors including medical history, co-treatments, age, gender, and ghrelin measurement techniques. Interestingly, rats treated with olanzapine, an SGA with high weight gain liabilities, are associated with increased hypothalamic ghrelin receptor (GHS-R1a) levels. In addition, expressions of downstream ghrelin signalling parameters at the hypothalamus, including neuropeptide Y (NPY)/agouti-related peptide (AgRP) and proopiomelanocortin (POMC) are also altered under SGA treatments. Thus, understanding the role of ghrelin signalling in antipsychotic drug-induced weight gain should offer potential novel pharmacological targets for tackling the obesity side-effect of SGAs and its associated metabolic syndrome.

With rates of obesity and diabetes rising worldwide, effective ways of managing weight are becoming more important. We present the case study of a middle-aged Caucasian-American woman (body mass index (BMI) 27.8, overweight category) who wanted to lose weight. The patient participated in a behaviour modification programme with a physician trained in lifestyle medicine as well as health and wellness coaching. After the 14-week programme, which included 9, 1 h long walking sessions with the clinician, the patient lost 11 Ibs (BMI 24.7, normal category). The programme included a combination of increasing physical activity, eating appropriate quantities of healthy foods, goal setting and a positive attitude. The patient has kept her BMI at or below 24.1 for over 2 years. This case demonstrates a novel approach to weight loss management--walking therapeutic sessions--and also outlines critical components of lifestyle medicine counselling that facilitate the process of sustainable weight loss and lasting change. 2016 BMJ Publishing Group Ltd.

Background Weight gain in pregnancy is an essential physiological adaptation, supporting growth and development of a fetus, and is distributed among lean mass including total body water, and fat mass gains. Although gestational weight gain provides a source of energy for the mother and fetus, excess gestational weight gain may underlie reported associations between parity and future metabolic disorders, and is linked to postpartum weight retention and insulin resistance. Although weight gain is often proposed as a modifiable variable to mitigate adverse maternal and offspring health outcomes, our knowledge of specific maternal body composition changes with weight gain, and the potential metabolic consequences, is limited. Furthermore, although gestational weight gain alters maternal body composition, the impact of excess weight gain on fat and lean mass is not well studied. Understanding the accrual of fat and lean body mass may improve our understanding of the role of excessive gestational weight gain and metabolic dysfunction. Objective To quantify the relationship between gestational weight gain and maternal fat and lean body mass accrual, and to compare fat and lean body mass accrual according to 2009 Institute of Medicine Guidelines for Gestational Weight Gain in Pregnancy adherence. We hypothesized that exceeding current weight gain guidelines would be associated with greater fat, compared with lean body, mass accrual. Study Design This is a secondary analysis of a randomized controlled trial of 49 overweight/obese women; all 49 are included in this secondary analysis. Maternal weight and body composition using air densitometry (BOD POD) were collected in early (13 0/6-16 6/7 weeks) and late (34 0/7-36 6/7 weeks) pregnancy. Correlations were made between gestational weight gain and change in fat and lean body mass. We compared change in fat and lean body mass by adherence to 2009 Institute of Medicine Guidelines for Gestational Weight Gain in Pregnancy

The food addiction model proposes that obesity overlaps with addiction in terms of neurobiological alterations in the striatum and related clinical manifestations (i.e., craving and persistence of unhealthy habits). Therefore, we aimed to examine the functional connectivity of the striatum in excess-weight versus normal-weight subjects and to determine the extent of the association between striatum connectivity and individual differences in food craving and changes in body mass index (BMI). Forty-two excess-weight participants (BMI > 25) and 39 normal-weight participants enrolled in the study. Functional connectivity in the ventral and dorsal striatum was indicated by seed-based analyses on resting-state data. Food craving was indicated with subjective ratings of visual cues of high-calorie food. Changes in BMI between baseline and 12 weeks follow-up were assessed in 28 excess-weight participants. Measures of connectivity in the ventral striatum and dorsal striatum were compared between groups and correlated with craving and BMI change. Participants with excess weight displayed increased functional connectivity between the ventral striatum and the medial prefrontal and parietal cortices and between the dorsal striatum and the somatosensory cortex. Dorsal striatum connectivity correlated with food craving and predicted BMI gains. Obesity is linked to alterations in the functional connectivity of dorsal striatal networks relevant to food craving and weight gain. These neural alterations are associated with habit learning and thus compatible with the food addiction model of obesity. Copyright © 2016 Society of Biological Psychiatry. Published by Elsevier Inc.

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.

Maternal weight before and during pregnancy is associated with offspring neurobehaviour in childhood. We investigated maternal weight prior to and during pregnancy in relation to neonatal neurobehaviour. We hypothesized that maternal obesity and excessive gestational weight gain would be associated with poor neonatal attention and affective functioning. Participants (n = 261) were recruited, weighed and interviewed during their third trimester of pregnancy. Pre-pregnancy weight was self-reported and validated for 210 participants, with robust agreement with medical chart review (r = 0.99). Neurobehaviour was measured with the NICU Network Neurobehavioural Scale (NNNS) administered on Days 2 and 32 postpartum. Maternal exclusion criteria included severe or persistent physical or mental health conditions (e.g. chronic disease or diagnoses of Bipolar Disorder or Psychotic Spectrum Disorders), excessive substance use, and social service/foster care involvement or difficulty understanding English. Infants were from singleton, full-term (37-42 weeks gestation) births with no major medical concerns. Outcome variables were summary scores on the NNNS (n = 75-86). For women obese prior to pregnancy, those gaining in excess of Institute of Medicine guidelines had infants with poorer regulation, lower arousal and higher lethargy. There were no main effects of maternal pre-pregnancy body mass index on neurobehaviour. Women gaining above Institute of Medicine recommendations had neonates with better quality of movement. Additional studies to replicate and extend results past the neonatal period are needed. Results could support underlying mechanisms explaining associations between maternal perinatal weight and offspring outcomes. These mechanisms may inform future prevention/intervention strategies. © 2016 Blackwell Publishing Ltd. © 2016 Blackwell Publishing Ltd.

Weight gain associated with antipsychotics in schizophrenia has been an ongoing concern. This meta-analysis examined the efficacy and safety of amantadine as an adjunctive treatment of weight gain in schizophrenia by systematically searching and analyzing randomized controlled trials (RCTs). RCTs comparing adjunctive amantadine with placebo in adult patients with schizophrenia were included in the meta-analysis. Two independent investigators searched the literature and extracted data. Weighted and standardized mean differences (WMDs/SMDs) and risk ratio ± 95% confidence intervals were calculated. Five RCTs (n = 265) with double-blinded design lasting 8.2 ± 5.9 weeks were included in the analysis. Amantadine outperformed placebo regarding weight reduction with moderate effect size (trials, 3; n = 205; WMD -2.22 kg; P = 0.001, I = 45%). Amantadine also outperformed placebo at endpoint in the negative symptom (the Positive and Negative Syndrome Scale [PANSS] [1 trial] and the Scale for the Assessment of Negative Symptoms [1 trial]) scores (trials, 2; n = 84; SMD, -0.56; P = 0.01, I = 12%), but not in the PANSS total scores (trials, 2) (SMD, -0.31; P = 0.16, I = 0%) and the positive symptom (PANSS [1 trial] and the Scale for the Assessment of Positive Symptoms [1 trial]) scores (SMD, 0.13; P = 0.54, I = 0%). Except for insomnia (P = 0.007; number needed to harm, 6; 95% confidence interval, 4-16), all-cause discontinuation (risk ratio, 1.12; P = 0.54, I = 0%) and other adverse events were similar between the amantadine and placebo groups. According to this meta-analysis of 5 RCTs, adjunctive amantadine seems to be an effective option for attenuating antipsychotic-related weight gain in patients with schizophrenia. More RCTs are needed to inform clinical recommendations.

The administration of antipsychotic drugs to human patients or experimental animals leads to significant weight gain, which is widely presumed to be driven by hyperphagia; however, the contribution from energy expenditure remains unclear. These studies aim to examine the contribution of shifts in energy expenditure, particularly those involving centrally mediated changes in thermogenesis, to the body weight gain associated with the administration of olanzapine to female Sprague Dawley rats. Olanzapine (6 mg/kg/day orally) caused a transient increase in food intake but a maintained increase in body weight. When pair-fed rats were treated with olanzapine, body weight continued to rise compared to vehicle-treated rats, consistent with a reduction in energy expenditure. Brown adipose tissue (BAT) temperature, measured using biotelemetry devices, decreased immediately after the onset of olanzapine treatment and remained depressed, as did physical activity. UCP1 expression in interscapular BAT was reduced following chronic olanzapine treatment. An acute injection of olanzapine was preceded by an injection of a retrograde tracer into the spinal cord to evaluate the nature of the olanzapine-activated neural pathway. Levels of Fos protein in a number of spinally projecting neurons within discrete hypothalamic and brainstem sites were elevated in olanzapine-treated rats. Some of these neurons in the perifornical region of the lateral hypothalamus (LHA) were also Orexin A positive. These data collectively show a significant impact of thermogenesis (and physical activity) on the weight gain associated with olanzapine treatment. The anatomical studies provide an insight into the central neuroanatomical substrate that may subserve the altered thermogenic responses brought about by olanzapine.

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. PMID:25685394

Administering monosodium glutamate (MSG) to neonatal rodents induces obesity and type 2 diabetes. In addition, several studies have shown that MSG administered to pregnant animals can cross the placenta and reach the foetus. The present study was performed to investigate the effects of administering MSG to pregnant ICR mice on dam and neonatal growth. Pregnant mice were treated with 60 or 120 mg MSG once daily from day 5 of pregnancy to one day before parturition by subcutaneous injection. In addition, the body weights of the neonates were determined until nine weeks of age. The birth weights of neonates were not different between the control and MSG-treated groups. However, MSG treatment resulted in a lower body weight gain of neonates during lactation. In addition, this underweight of the MSG-treated group at weaning returned to normal compared with the control group at five weeks of age. Cross-fostering experiments indicated that the lower body weight gain of neonates in the MSG-treated group during lactation was due to its effects on the dam. Serum prolactin levels and mammary gland development of the mice were examined next to determine the reasons for this lactation problem. Although there were no differences in prolactin levels, morphological analyses of the mammary glands revealed apparent differences, including low numbers and altered phenotype of alveoli, between the control and MSG-treated groups. Taken together, our results show that treating pregnant mice with excess MSG induced lower neonate body weight gain during lactation. © The Author(s) 2015.

To determine the prevalence of excessive gestational weekly weight gain and to identify its association with demographic, socioeconomic, obstetric, anthropometric, and behavioral characteristics. This cross-sectional study included 328 pregnant women attending all health units in the urban area of Vitória da Conquista, Bahia. The data were collected from May 2010 to June 2011. The weekly weight gain was evaluated according to the current recommendations of the Institute of Medicine. The association among the studied factors and the excessive weekly weight gain was observed in pregnant women in the second and third trimesters, using the Poisson regression with robust variance. The prevalence rate of excessive weekly weight gain in pregnant women in the second and third trimesters was found to be 42.5%. The determinants of excessive weekly weight gain were family income < 1 minimum wage (PR: 2.65; 95%CI 1.18 - 4.83) and pregestational weight status overweight/obesity (PR: 1.33; 95%CI 1.01 - 1.75). The results emphasize the importance of monitoring the weight gain during pregnancy. The evaluation of the weekly weight gain enables early interventions with the goal of preventing the excessive total weight gain and its consequences for both the mother and the child.

High prepregnancy body mass index (BMI), excessive gestational weight gain (GWG), and gestational diabetes mellitus (GDM) are associated with the risk of childhood obesity. This study aims to examine the extent to which these effects may be mediated through the placenta. Data included 33,893 mothers and their singleton infants from birth to 7 years old (total 154,590 visits) in the Collaborative Perinatal Project, a U.S. multicenter prospective cohort study from 1959 to 1976. The placentas were weighed after removing cord and membranes. We performed sequential generalized estimating equation-linear models excluding and including placental weight to evaluate its mediation effect. In this population, 21.7% of mothers had overweight or obesity, 17.3% had excessive GWG, and 350 (1%) had diagnosed GDM; in addition, 7.2% children had obesity. After adjustment for prepregnancy BMI and other covariates, childhood BMI was 0.23 (95% CI: 0.05, 0.40) kg/m(2) higher for children born to mothers with GDM versus those without GDM. Inclusion of placental weight in the model attenuated the association by 52% to 0.11 (95% CI: -0.06, 0.28) and similarly attenuated the associations with childhood BMI for GWG by 25% and maternal prepregnancy BMI by 17%. Placental weight partly mediates the effects of prepregnancy BMI, excessive GWG, and GDM on childhood BMI. © 2016 The Obesity Society.

Nasal obstruction is a risk factor in sleep-disordered breathing with a negative impact on the quality of life in humans. We investigated hydration changes produced by short term reversible, bilateral, nasal obstruction in young developing rat pups. Physiological parameters of growth (weight gain and gastric content weight) and dehydration were analyzed during two periods; during nasal obstruction at post-natal day 8 (days 9, 11 and 13), plus 7 and 90 days after recovery of nasal breathing (day 15 and adulthood). Body weight gain in oral breathing rat pups was slower compared to controls. Gastric weight was decreased significantly only in oral breathing rat pups on days 9 and 11 while plasma osmolality and vasopressin levels increased (indicators of dehydration). There were no differences between controls and treated rat pups by day 15, or at adulthood. Short term nasal obstruction-induced forced oral breathing, decreased gastric content which had a negative impact on growth and blood glucose concentration in the short term for female rat pups. Plasma corticosterone levels increased during the dehydration but were normal in males by 90 days. This could be a model for blocked nose syndrome in the newborn. Possible long term consequences on development are discussed. Copyright Â© 2010 Elsevier Inc. All rights reserved.

To evaluate whether nutritional management intervention can prevent excessive weight gain during pregnancy and improve perinatal outcomes. This cross-sectional study included 276 pregnant women undergoing prenatal care between June 2010 and December 2011 at the Obstetrics and Gynecology Department of the Second Affiliate Hospital of the ChongQing University of Medical Sciences, Chongqing, China. Of them, 131 women received individualized nutritional management in addition to routine prenatal care (intervention group), and 145 women received only routine prenatal care (control group). The primary study outcome was gestational weight gain (GWG). Secondary outcomes included birth weight, Apgar score, and incidence of pregnancy complications. Baseline demographic characteristics of the 2 groups were the same. The average GWG was higher in the control group (12.57+/-4.62 kg) compared with the intervention group (7.58+/-1.59 kg; p=0.000). The incidence rate of preeclampsia was 3.1% and gestational diabetes was 3.8% for the intervention group, compared with 11% for preeclampsia and 14.5% gestational diabetes for the control group (p<0.05). The incidence rates of premature rupture of membranes, preterm labor, birth weight, birth of a newborn, and major congenital anomalies did not significantly differ between the 2 groups. Nutritional management intervention prevented excessive GWG and improved perinatal outcomes. These results support the hypothesis that nutritional management intervention can decrease the rate of complications experienced by expecting mothers.

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 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.

Dietary composition may affect insulin secretion, and high insulin levels, in turn, may increase the risk for cardiovascular disease (CVD). To examine the role of fiber consumption and its association with insulin levels, weight gain, and other CVD risk factors compared with other major dietary components. The Coronary Artery Risk Development in Young Adults (CARDIA) Study, a multicenter population-based cohort study of the change in CVD risk factors over 10 years (1985-1986 to 1995-1996) in Birmingham, Ala; Chicago, III; Minneapolis, Minn; and Oakland, Calif. A total of 2909 healthy black and white adults, 18 to 30 years of age at enrollment. Body weight, insulin levels, and other CVD risk factors at year 10, adjusted for baseline values. After adjustment for potential confounding factors, dietary fiber showed linear associations from lowest to highest quintiles of intake with the following: body weight (whites: 174.8-166.7 lb [78.3-75.0 kg], PFiber was also associated with blood pressure and levels of triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and fibrinogen; these associations were substantially attenuated by adjustment for fasting insulin level. In comparison with fiber, intake of fat, carbohydrate, and protein had inconsistent or weak associations with all CVD risk factors. Fiber consumption predicted insulin levels, weight gain, and other CVD risk factors more strongly than did total or saturated fat consumption. High-fiber diets may protect against obesity and CVD by lowering insulin levels.

This survey evaluated the effects of physical activity on gestational weight gain and birth weight of pregnant women attended by the Family Health Program in Campina Grande, Northeast of Brazil. A cohort study enrolling 118 pregnant women was conducted between 2005 and 2006. Evaluation of the initial nutritional status was performed following Atalah's criteria and gestational weight gain was evaluated according to the Institute of Medicine. The pattern of physical activity was evaluated according to METs (metabolic equivalent) and its association with weight gain and birth weight was determined. The predominant physical activity pattern at 16 weeks was mild, in 85.6% of pregnant women. An important reduction of physical activity levels was observed with evolution of pregnancy and 98.3% of pregnant women were sedentary at 24 weeks and 100% at 32 weeks. In the initial evaluation of nutritional status 50% were normal, 23% had low weight and 27% had overweight/obesity. At second and third trimesters about 45% of pregnant women had excessive weight gain. Adequate birth weight for gestational age was found in 85.6% of neonates but macrosomia was highly frequent (8.5%). A significant association between METs at 24 weeks and gestational weight gain was found in the second trimester (p=0.045). All the pregnant women were sedentary in the third trimester and a significant association between physical activity pattern and gestational weight gain was found in the second trimester, but there was no association between this pattern and birth weight.

Behavioral studies reveal that obese vs. lean individuals show attentional bias to food stimuli. Yet research has not investigated this relation using objective brain imaging or tested whether attentional bias to food stimuli predicts future weight gain, which are important aims given the prominence of food cues in the environment. We used functional magnetic resonance imaging (fMRI) to examine attentional bias in 35 adolescent girls ranging from lean to obese using an attention network task involving food and neutral stimuli. BMI correlated positively with speed of behavioral response to both appetizing food stimuli and unappetizing food stimuli, but not to neutral stimuli. BMI correlated positively with activation in brain regions related to attention and food reward, including the anterior insula/frontal operculum, lateral orbitofrontal cortex (OFC), ventrolateral prefrontal cortex (vlPFC), and superior parietal lobe, during initial orientation to food cues. BMI also correlated with greater activation in the anterior insula/frontal operculum during reallocation of attention to appetizing food images and with weaker activation in the medial OFC and ventral pallidum during reallocation of attention to unappetizing food images. Greater lateral OFC activation during initial orientation to appetizing food cues predicted future increases in BMI. Results indicate that overweight is related to greater attentional bias to food cues and that youth who show elevated reward circuitry responsivity during food cue exposure are at increased risk for weight gain.

Severity of obstructive sleep apnea (OSA) is estimated based on respiratory events per hour [i.e., apnea-hypopnea index (AHI)]. The aim of this study was to investigate effects of weight change on the severity of respiratory events. Respiratory event severity, including duration and morphology, was estimated by determining parameters quantifying obstruction and desaturation event lengths and areas, respectively. Respiratory events of 54 OSA patients treated with dietary intervention were evaluated at baseline and after 5-year follow-up in subgroups with different levels of weight change. AHI, oxygen desaturation index (ODI) and obstruction event severities decreased during weight loss. In lower level weight loss, the decrease was milder in obstruction severity than in AHI and ODI, indicating that the decrease in the number of events is more focused on less severe events. In weight gain groups, parameters incorporating obstruction event severity, AHI and ODI increased, although increase was greater in parameters incorporating obstruction event severity. The number and severity of respiratory events were modulated differently by the level of weight change. AHI misses this change in the severity of respiratory events. Therefore, parameters incorporating information on the respiratory event severities may bring additional information on the health effects obtained with dietary treatment of OSA.
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.

Young adults attending college are more vulnerable to weight gain than the general population. We sought to identify health behavior change targets related to weight management in college students. Based on the Social Cognitive Theory model for health behavior change, we investigated the health-related lifestyle behaviors and physiological characteristics of this population. Forty-three college students (18.3+/-0.1 years) completed a series of quantitative assessments (eg, body weight and composition, cardiorespiratory fitness, and diet and activity habits) and structured qualitative assessments (ie, structured interview or focus group). Participants were predominantly normal weight (mean body mass index 22.2+/-0.4) and fit (maximal oxygen consumption 50.5+/-1.5 mL/kg/minute). However, healthful eating and physical activity were not considered high priorities, despite having ample free time, high exercise self-efficacy, positive outcome expectations for exercise, and a desire to exercise more. Participants reported that regularly engaging in exercise was difficult. This may have been due to poor planning/time management, satisfaction with body image, lack of accountability, and feelings of laziness. Dietary patterns generally met recommendations but were low in fruits, vegetables, and whole grains. Social support for exercise and healthful dietary habits were important factors associated with health behaviors. Students reported a decline in exercise and dietary habits relative to high school, which may have contributed to college weight gain. Our results suggest that this population may not have adequate self-regulatory skills, such as planning and self-monitoring, to maintain healthful behaviors in the college environment. Food and nutrition professionals working with young adults attending college may use these findings to guide the behavioral therapy component of their weight management medical nutrition therapy goals and outcomes.

To explain weight gain patterns in the first two years of life, we compared the predictive values of potential risk factors individually and within four different domains: prenatal, nutrition, lifestyle and socioeconomic factors. In a Dutch population-based birth cohort, length and weight were measured in 2475 infants at 1, 6, 12 and 24 months. Factors that might influence weight gain (e.g. birth weight, parental BMI, breastfeeding, hours of sleep and maternal education) were retrieved from health care files and parental questionnaires. Factors were compared with linear regression to best explain differences in weight gain, defined as changes in Z-score of weight-for-age and weight-for-length over 1-6, 6-12 and 12-24 months. In a two-step approach, factors were first studied individually for their association with growth velocity, followed by a comparison of the explained variance of the four domains. Birth weight and type of feeding were most importantly related to weight gain in the first six months. Breastfeeding versus formula feeding showed distinct growth patterns in the first six months, but not thereafter. From six months onwards, the ability to explain differences in weight gain decreased substantially (from R2total = 38.7% to R2totalweight and breast feeding were most important to explain early weight gain, especially in the first six months of life. After the first six months of life other yet undetermined factors start to play a role.

Prospective comparative study. To evaluate whether weight percentile (WP) increases after VEPTR insertion, and whether WP correlates with nutrition labs and pulmonary function. Children with thoracic insufficiency syndrome (TIS) often have "failure to thrive" (WP ≤5). Previous authors have reported an increase in WP after VEPTR surgery. Weight gain was hypothesized to be secondary to improved pulmonary function. The presence of a correlation between WP, and nutrition labs and pulmonary function tests (PFT) after VEPTR insertion has not been studied. Demographic, nutrition, radiographic, and PFT data were collected on 35 VEPTR patients with a minimum follow-up of 2 years. The relationship between WP, and nutrition labs and pulmonary function was analyzed. Preoperative WP was ≤5 (PREOP≤5) in 13 patients (37%) and >5 (PREOP>5) in 22 patients (63%). Although all children gained weight, the PREOP≤5 group was more likely to have an increase in WP (P = 0.014). Sixty-eight percent of the PREOP>5 group had a decrease in WP and 32% of the PREOP>5 patients met the criteria for failure to thrive at final follow-up. Overall, there was no change in the number of children with a WP ≤5 (13 vs 15). Forty-two percent of the children who maintained or increased their WP had a gastrostomy tube, compared to 19% of those who decreased their WP. Seventy-three percent of the patients with failure to thrive at final follow-up did not have a gastrostomy tube. No significant correlations were found between WP and nutrition labs, radiographic measures, or PFTs. We did not find an overall change in WP after VEPTR insertion. We did not find any correlation between WP and nutrition labs or pulmonary function. Weight gain after VEPTR surgery may be secondary to nutritional optimization in high-risk patients. Children who do not have failure to thrive at presentation also require attention. 2.

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.

There is a wide acknowledgement of obesity as a relevant clinical entity. Such relevance can be inferred by the huge worldwide amount of research and related health promotion and clinical efforts. Though the evidence sustains some cues for the therapeutic success, the overall long-term effectiveness of obesity treatment tends to be not so satisfactory. Scientific literature is not unequivocal in key areas of nutritional intervention, such as the magnitude of caloric restriction, proportion of macronutrients, meal frequency, among others. The same applies to the area of physical activity recommendation for weight control. As a correlate of this scenario of incertitude, there is a proliferation of interventions and there is a clear need to integrate the scientific and clinical evidence. This paper presents a narrative literature review of key issues of clinical practice in obesity, regarding a set of actions that, in the overall, have as main purpose the promotion of reduction and/or control of body weight. The role of the health professional is highlighted as a facilitator of acquisition of habits that favor weight control, by integrating the professional's scientific knowledge with the patient's readiness for and capacity to change.

There is a plethora of cross-sectional work on maternal perceptions of child weight status showing that mothers typically do not classify their overweight child as being overweight according to commonly used clinical criteria. Awareness of overweight in their child is regarded as an important prerequisite for mothers to initiate appropriate action. The gap in the literature is determining whether, if mothers do classify their overweight child's weight status correctly, this is associated with a positive outcome for the child's body mass index (BMI) at a later stage. To explore longitudinal perceptions of child weight status from mothers of a contemporary population-based birth cohort (Gateshead Millennium Study) and relationships of these perceptions with future child weight gain. Data collected in the same cohort at 7, 12 and 15 years of age: mothers' responses to two items concerning their child's body size; child's and mother's BMI; pubertal maturation; demographic information. Mothers' perceptions of whether their child was overweight did not change markedly over time. Child BMI was the only significant predictor of mothers' classification of overweight status, and it was only at the extreme end of the overweight range and in the obese range that mothers reliably described their child as overweight. Even when mothers did appropriately classify their child as overweight at an earlier stage, this was not related to relatively lower child BMI a few years later. Mothers tend to classify their child as overweight in only more extreme cases. It is an important finding that no beneficial impact was shown on later child BMI in overweight children whose mothers classified their child's weight status as overweight at an earlier stage.
Full Text Available Abstract Background Nearly 60% of black women are obese. Despite their increased risk of obesity and associated chronic diseases, black women have been underrepresented in clinical trials of weight loss interventions, particularly those conducted in the primary care setting. Further, existing obesity treatments are less effective for this population. The promotion of weight maintenance can be achieved at lower treatment intensity than can weight loss and holds promise in reducing obesity-associated chronic disease risk. Weight gain prevention may also be more consistent with the obesity-related sociocultural perspectives of black women than are traditional weight loss approaches. Methods/Design We conducted an 18-month randomized controlled trial (the Shape Program of a weight gain prevention intervention for overweight black female patients in the primary care setting. Participants include 194 premenopausal black women aged 25 to 44 years with a BMI of 25–34.9 kg/m2. Participants were randomized either to usual care or to a 12-month intervention that consisted of: tailored obesogenic behavior change goals, self-monitoring via interactive voice response phone calls, tailored skills training materials, 12 counseling calls with a registered dietitian and a 12-month YMCA membership. Participants are followed over 18 months, with study visits at baseline, 6-, 12- and 18-months. Anthropometric data, blood pressure, fasting lipids, fasting glucose, and self-administered surveys are collected at each visit. Accelerometer data is collected at baseline and 12-months. At baseline, participants were an average of 35.4 years old with a mean body mass index of 30.2 kg/m2. Participants were mostly employed and low-income. Almost half of the sample reported a diagnosis of hypertension or prehypertension and 12% reported a diagnosis of diabetes or prediabetes. Almost one-third of participants smoked and over 20% scored above the clinical threshold

Objective To describe African American and White women’s perceptions of weight gain, physical activity, and nutrition during pregnancy and to explore differences in perceptions by race. Design Qualitative interview study. Setting Two Ob/Gyn clinics in South Carolina, USA. Participants Thirty pregnant women (15 African American, 15 White) between 20–30 weeks gestation, equally represented across pre-pregnancy BMI categories (10 normal weight, 10 overweight, and 10 obese). Findings White women more frequently described intentions to meet weight gain, physical activity, and dietary guidelines in pregnancy than African American women. African American women were more concerned with inadequate weight gain while White women more commonly expressed concerns about excessive weight gain. More White women discussed the importance of physical activity for weight management. Regardless of race, few women described risks of excessive weight gain or benefits of physical activity as it relates to the baby’s health. The primary cited barrier of healthy eating was the high cost of fresh produce. Key conclusions and implications for practice Several knowledge gaps as well as race differences were identified in women’s perceptions and intentions toward weight gain, physical activity, and nutrition during pregnancy. Future interventions should seek to educate women about common misperceptions. It may be necessary to culturally tailor gestational weight gain interventions to optimize health outcomes.

Maternal obesity and weight gain during pregnancy are risk factors for child obesity. Associations may be attributable to causal effects of the intrauterine environment or genetic and postnatal environmental factors. We estimated associations of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) overall and in early pregnancy, midpregnancy, and late pregnancy with neonatal adiposity. Participants were 826 women enrolled in a Colorado prebirth cohort who delivered term infants (2010-2013). GWG to 39 wk of gestation was predicted by using mixed models, and early pregnancy, midpregnancy, and late pregnancy rates of GWG (0-17, 17-27, and 27 wk to delivery) were calculated from repeated weight measures. Neonatal body composition was measured by using air-displacement plethysmography ≤3 d after birth. Each1-kg/m(2) increase in maternal BMI was associated with increased neonatal fat mass (5.2 g; 95% CI: 3.5, 6.9 g), fat-free mass (7.7 g; 95% CI: 4.5, 10.9 g), and percentage of body fat (0.12%; 95% CI: 0.08%, 0.16%). Each 0.1-kg/wk increase in predicted GWG was associated with increased fat mass (24.0 g; 95% CI: 17.4, 30.5 g), fat-free mass (34.0 g; 95% CI: 21.4, 46.6 g), and percentage of body fat (0.55%; 95% CI: 0.37%, 0.72%). No interaction was detected between BMI and GWG in their effects on neonatal body composition. Early pregnancy, midpregnancy, and late pregnancy rates of GWG were independently associated with fat mass and percentage of body fat. Midpregnancy and late pregnancy GWGs were associated with fat-free mass. An observed GWG that exceeded recommendations was associated with higher neonatal fat mass and fat-free mass but not percentage of body fat relative to adequate GWG. Maternal prepregnancy BMI and GWG, including period-specific GWG, were positively and independently associated with neonatal adiposity. Associations of early and midpregnancy weight gain with neonatal adiposity support the hypothesis that greater maternal
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 Abstract Background Most clinical trials of antipsychotics in children are brief, failing to address their long-term safety, particularly when taken concurrently with other psychotropics. This hypothesis-generating analysis evaluates potential correlates of weight gain in children receiving extended risperidone treatment. Methods Medically healthy 7–17 year-old patients treated with risperidone for six months or more were enrolled. Anthropometric measurements were conducted. Developmental and medication history was obtained from the medical record. Information related to birth weight, dietary intake, physical activity, and parental weight was collected. Mixed regression analyses explored the contribution of various demographic and clinical factors to age- and sex-adjusted weight and body mass index (BMI z scores over the treatment period. Results The sample consisted of 110 patients (89% males with a mean age of 11.8 years (sd = 2.9 upon enrollment. The majority had an externalizing disorder and received 0.03 mg/kg/day (sd = 0.02 of risperidone, for 2.5 years (sd = 1.7, to primarily target irritability and aggression (81%. Polypharmacy was common with 71% receiving psychostimulants, 50% selective serotonin reuptake inhibitors (SSRIs, and 32% α2-agonists. Weight and BMI z score were positively correlated with baseline weight at the start of risperidone, treatment duration, and the weight-adjusted dose of risperidone but inversely associated with the weight-adjusted dose of psychostimulants and the concurrent use of SSRIs and α2-agonists. The effect of risperidone dose appeared to attenuate as treatment extended while that of psychostimulants became more significant. The rate of change in weight (or BMI z score prior to and within the first 12 weeks of risperidone treatment did not independently predict future changes neither did birth weight, postnatal growth, dietary intake, physical activity, or parental weight

This study prospectively assessed the association of the inflammatory potential of a diet using the dietary inflammatory index (DII) with average yearly weight changes and incident overweight/obesity. Seven thousand and twenty-seven university graduates with body mass index <25 from the Seguimiento Universidad de Navarra (SUN) cohort were followed up during a median of 8.1 years. The DII, a validated tool based on scientific evidence to appraise the relationship between dietary parameters and inflammatory biomarkers, was used. A validated food-frequency questionnaire was used to assess intake of total energy, food, and nutrients, from which DII scores were calculated at baseline and after 10 years of follow-up. After a median follow-up of 8.1 years, 1,433 incident cases of overweight or obesity were observed. Hazard ratios for overweight/obesity were calculated, including multivariable time-dependent Cox regression models with repeated measures of diet. The hazard ratio for subjects in the highest quartile (most pro-inflammatory diet) was 1.32 (95% confidence interval 1.08-1.60) compared with participants in the lowest quartile (most anti-inflammatory diet), with a significant linear dose-response relationship (P = 0.004). Consistently, increases in average yearly weight gains were significantly associated with proinflammatory diets. A proinflammatory diet was significantly associated with a higher annual weight gain and higher risk of developing new-onset overweight or obesity. © 2017 The Obesity Society.

To examine the associations between the lifestyle factors-sports, alcohol, nutrition, overweight, and smoking, the eating styles of dietary restraint, external eating, and emotional eating on the one hand, and the change in body mass index (BMI) on the other hand. Using a Web-based lifestyle questionnaire, responses were obtained from 1562 employees. We found a consistent main effect of emotional eating and doing sports on change in BMI. High emotional eating was related to weight gain, whereas a high level of sporting was related to weight loss. Restrained eating and external eating were not found to have a significant influence on change in BMI. Additionally, a consistent moderator effect of sporting on emotional eating was found (P sports compared with those with low engagement in strenuous sports. This indicates that strenuous physical activity can indeed attenuate the positive association between emotional eating and body weight gain. Emotions may drive people with overweight and obesity to overeat. Sports activities may attenuate but do not solve the problem. If we want to cure the disease, psychological treatment strategies have to be developed.

Weight gain accompanied by an increased tendency for central fat distribution is common among women in midlife. These changes are a result of aging, decreasing estrogen levels after menopause, and other unique influences in menopausal women that interfere with the adoption of healthy lifestyle measures. Central obesity, in particular, results in several adverse metabolic consequences, including dysglycemia, dyslipidemia, hypertension, and cardiovascular disease. Given that cardiovascular disease is the leading cause of death in postmenopausal women, the importance of weight management in midlife cannot be overemphasized. In addition, weight gain in midlife contributes to other health risks including cancer, arthritis, mood disorders, and sexual dysfunction. It is imperative that primary care physicians screen midlife women for overweight/obesity and offer appropriate advice and referral. In addition to counseling regarding lifestyle change, behavioral modification, and psychological support, it is important to address the unique barriers to adoption of healthy lifestyle measures in postmenopausal women, including the presence of vasomotor symptoms, mood disorders, and sleep disturbance. When indicated, menopausal hormone therapy should be considered to manage bothersome symptoms. Despite its favorable influence on body fat distribution, menopausal hormone therapy cannot be recommended as a treatment for central obesity in midlife women.
