    2013-01-01

    Cost-effective, sustainable strategies are urgently required to curb the global obesity epidemic. To date, fiscal policies such as taxes and subsidies have been driven largely by imperatives to raise revenue or increase supply, rather than to change population behaviours. This paper reviews the economic evaluation literature around the use of fiscal policies to prevent obesity. The cost-effectiveness literature is limited, and more robust economic evaluation studies are required. However, unc...

    Full Text Available Obesity is a public health problem that has become epidemic worldwide. Substantial literature has emerged to show that overweight and obesity are major causes of co-morbidities, including type II diabetes, cardiovascular diseases, various cancers and other health problems, which can lead to further morbidity and mortality. The related health care costs are also substantial. Therefore, a public health approach to develop population-based strategies for the prevention of excess weight gain is of great importance. However, public health intervention programs have had limited success in tackling the rising prevalence of obesity. This paper reviews the definition of overweight and obesity and the variations with age and ethnicity; health consequences and factors contributing to the development of obesity; and critically reviews the effectiveness of current public health strategies for risk factor reduction and obesity prevention.

    Full Text Available Childhood obesity is the metabolic disorder with the highest prevalence in both children and adults. Urgency to treat and prevent childhood obesity is based on the clear evidence that obesity tends to track from childhood to adulthood, is associated to morbidity also in childhood and to long-term mortality. Early life, i.e., intrauterine life and the first two years, is a sensitive window for prevention. Anatomical and functional maturation of the hypothalamic structures devoted to regulating energy intake and expenditure and body size mainly occurs in the first 1,000 days of life. Therefore, factors affecting the foetal exposition to maternal metabolic environment and early postnatal nutrition are crucial in modulating the definition of the metabolic programming processes in the brain. Maternal diseases, mainly malnutrition for defect or excess, obesity and diabetes, placental disorders and dysfunctions, maternal use of alcohol and drugs, smoking, affect long term metabolic programming of the foetus with lifelong consequences. Similarly, early nutrition contributes to complete the long-term metabolic regulating framework initiated in the uterus. Breastfeeding, adequate weaning, attention to portion size and diet composition are potential tools for reducing the obesity risk later in childhood. Longitudinal randomized controlled studies are needed for exploring the efficacy of obesity prevention strategies initiated after conception.Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

    Background Childhood obesity has been increasing rapidly worldwide. There is limited evidence for effective lifestyle interventions to prevent childhood obesity worldwide, especially in developing countries like China. The objective of this study was to assess the effectiveness of a school-based multi-component lifestyle childhood obesity prevention program (the CLICK-Obesity study) in Mainland China. Methods A cluster randomized controlled trial was developed among grade 4 students from 8 urban primary schools (638 students in intervention, 544 as control) in Nanjing City, China. Students were randomly allocated to the control or intervention group at school-level. A one-year multi-component intervention program (classroom curriculum, school environment support, family involvement and fun programs/events) together with routine health education was provided to the intervention group, while the control group received routine health education only. The main outcome variables assessed were changes in body mass index, obesity occurrence, obesity-related lifestyle behaviors and knowledge. Results Overall, 1108 (93.7%) of the 1182 enrolled students completed the intervention study. The intervention group had a larger marginal reduction than did the control group in overall mean BMI value (-0.32±1.36 vs. -0.29±1.40, p = 0.09), although this was not significant. Compared with the control group, the intervention group was more likely to decrease their BMI (OR = 1.44, 95%CI = 1.10, 1.87) by 0.5 kg/m2 or above, increase the frequency of jogging/running (OR = 1.55, 95%CI = 1.18, 2.02), decrease the frequency of TV/computer use (OR = 1.41, 95%CI = 1.09, 1.84) and of red meat consumption (OR = 1.50, 95%CI = 1.15, 1.95), change commuting mode to/from school from sedentary to active mode (OR = 2.24, 95%CI = 1.47, 3.40), and be aware of the harm of selected obesity risk factors. Conclusions The school-based lifestyle intervention program was practical and effective in improving health behaviors and obesity-related knowledge for children in China. This study provides important policy implications on school-based intervention programs for modifications of obesity-related lifestyles.

    Full Text Available Elizabeth TeixeiraDrexel University College of Nursing and Health Professions, Philadelphia, PA, USAAbstract: Obesity is a major public health concern worldwide. The increasing prevalence of obesity in all ages, especially children and adolescents, has gained global attention and it is widely known that obesity increases the risk of many chronic conditions and illnesses, such as Type 2 Diabetes Mellitus (T2DM and cardiovascular disease (CVD. Obesity is a complex metabolic disorder, however, that is difficult to treat and manage. Therefore, despite the increased awareness about obesity-related health risks, obesity prevention and control has been a major challenge for health professionals. Lifestyle modification is easily prescribed, however, multiple barriers to implementation exist. Barriers include but are not limited to: behavioral and motivational factors, anti-fat bias, access to and reimbursement of educational programs, availability of healthy affordable foods, ongoing support systems that are culturally and community attuned, and comorbidities that limit physical activity and quality of life. Further, the current health care systems are not all designed to focus on health promotion and wellness. These contributing factors complicate weight management and control. Community-based programs are one potentially feasible approach that can assist individuals, families, and communities in developing healthy behaviors that promote and maintain weight loss. This review reports on nine worldwide current studies on the effectiveness of community-based programs in diverse populations targeting obesity. The purpose of this review is to examine evidenced-based interventions that can assist in the development of standard practices in the battle against obesity.Keywords: obesity, community, prevention, physical activity, nutrition

    The rise in income and population growth have increased the demand for food and induced changes in food habits, food purchasing and consumption patterns in Malaysia. With this transition, one of the plausible causes of weight gain and obesity is the frequent consumption of outside food which is synonymous with bigger portion size. Therefore, the aim of this paper is to develop a system dynamics model to analyse the effect of reducing food portion size on weight and obesity prevention. This study combines the different strands of knowledge comprise of nutrition, physical activity and body metabolism. These elements are synthesized into a system dynamics model called SIMULObese. Findings from this study suggested that changes in eating behavior should not emphasize only on limiting the food portion size consumption. The efforts should also consider other eating events such as controlling the meal frequency and limiting intake of high-calorie food in developing guidelines to prevent obesity.

    Obesity is the most common nutritionally related disease of dogs and cats. Several of the important health problems that are inherent with obesity are resolved when the patient's body weight is returned to normal. Proper dietary management is central to successful treatment and prevention. Low-fat, high-fiber diets provide fewer available calories but induce a greater degree of satiety than simple restriction of the obese patient's regular food. Care must be taken to assure that overweight cats are not fasted, because preliminary reports indicate an alarming association between severe caloric restriction and hepatic lipidosis in obese cats. Obesity prevention should ideally be proactive, owing to the predictability of obesity in certain groups of pets. The large number of reduced-energy maintenance type diets that are available for obesity prevention facilitate this goal. PMID:2658285

    Obesity is a medical condition where an individual has an excessive amount of body fat. There are many factors contributing to obesity and one of them is the sedentary behaviour. Rapid development in industrialization and urbanization has brought changes to Malaysia's socioeconomic, especially the lifestyles of Malaysians. With this lifestyle transition, one of the impact is on weight and obesity. How does sedentary behaviour have an impact on the growth of Malaysian population's weight and obesity? What is the most effective sedentary behaviour preventing strategy to obesity? Is it through reduction in duration or frequency of sedentary behaviour? Thus, the aim of this paper is to design an intervention to analyse the effect of decreasing duration and frequency of sedentary behaviour on the population reversion trends of average weight (AW), average body mass index (ABMI), and prevalence of overweight and obesity (POVB). This study combines the different strands of sub-models comprised of nutrition, physical activity and body metabolism, and then synthesis these knowledge into a system dynamics of weight behaviour model, namely SIMULObese. Findings from this study revealed that Malaysian's adults spend a lot of time engaged in sedentary behaviour and this resulted in weight gain and obesity. Comparing between frequency and duration of sedentary behaviour, this study reported that reduced in duration or time spend in sedentary behaviour is a better preventing strategy to obesity compared to duration. As a summary, this study highlighted the importance of decreasing the frequency and duration of sedentary behaviour in developing guidelines to prevent obesity.

    The preschool years offer an opportunity to interrupt the trajectory toward obesity in black children. The Hip-Hop to Health Jr. Obesity Prevention Effectiveness Trial was a group-randomized controlled trial assessing the feasibility and effectiveness of a teacher-delivered weight control intervention for black preschool children. The 618 participating children were enrolled in 18 schools administered by the Chicago Public Schools. Children enrolled in the nine schools randomized to the intervention group received a 14-week weight control intervention delivered by their classroom teachers. Children in the nine control schools received a general health intervention. Height and weight, physical activity, screen time, and diet data were collected at baseline and postintervention. At postintervention, children in the intervention schools engaged in more moderate-to-vigorous physical activity (MVPA) than children in the control schools (difference between adjusted group means = 7.46 min/day, P = 0.02). Also, children in the intervention group had less total screen time (-27.8 min/day, P = 0.05). There were no significant differences in BMI, BMI Z score, or dietary intake. It is feasible to adapt an obesity prevention program to be taught by classroom teachers. The intervention showed positive influences on physical activity and screen time, but not on diet. Measuring diet and physical activity in preschool children remains a challenge, and interventions delivered by classroom teachers require both intensive initial training and ongoing individualized supervision.

    The percentage of failure and relapse in the treatment of obesity is high. Where possible, the preferred strategy for preventing obesity is to modify eating habits and lifestyles. This article aims to provide a framework for evidence on the most effective interventions for addressing childhood obesity, both from a prevention point of view, as well as reducing it, when it is already established. After a review of the scientific literature, the issues that must be considered both in the universal and selective prevention of childhood obesity are presented. Also, in light of the controversy over the tools for measuring and controlling the problem, some clarification is provided on the criteria. Finally, the approach to the prevention of overweight and obesity with a community perspective is separated, with two short protocols being offered with diagrams of the basic procedure to follow.

    The early signs of obesity are observable in early childhood. Although the most promising prevention approaches are family-centered, few relevant early prevention programs exist. This study evaluated the effects of an evidence-based, home-visiting intervention, the Family Check-Up (FCU), on the trajectory of children's weight gain. The FCU was designed to prevent the development of behavior problems by improving family management practices; children's weight has not been an explicit target. On the basis of previous research and conceptual models, we hypothesized that intervention effects on parenting practices, specifically caregivers' use of positive behavior support (PBS) strategies in toddlerhood, would mediate improvements in children's weight trajectories. A total of 731 indigent caregiver-child dyads from a multisite randomized intervention trial were examined. Observational assessment of parenting and mealtime behaviors occurred from age 2-5 years. The child's body mass index (BMI) was assessed yearly from age 5-9.5 years. Path analysis with a latent growth model revealed a significant indirect effect of the FCU on the trajectory of BMI in later childhood. Improvements in caregivers' PBS in toddlerhood, which was related to the nutritional quality of the meals caregivers served to the child during the mealtime task, served as the intervening process. Furthermore, findings indicate that the FCU prevents progression to overweight and obese status amongst at-risk children. These study results add to existing evidence that has demonstrated that family-based interventions aimed at improving general family management skills are effective at preventing weight gain. Future directions are discussed. PMID:25263212

    The extracts of Salacia reticulata (Salacia extract), a plant that has been used for the treatment of early diabetes, rheumatism and gonorrhea in Ayurveda, have been shown to have an anti-obesity effect and suppress hyperglycemia. In this study, the effects of Salacia extract on various symptoms of metabolic disorder were investigated and compared using these TSOD mice and non-obese TSNO mice. Body weight, food intake, plasma biochemistry, visceral and subcutaneous fat (X-ray and CT), glucose tolerance, blood pressure and pain tolerance were measured, and histopathological examination of the liver was carried out. A significant dose-dependent decline in the gain in body weight, accumulation of visceral and subcutaneous fat and an improvement of abnormal glucose tolerance, hypertension and peripheral neuropathy were noticed in TSOD mice. In addition, hepatocellular swelling, fatty degeneration of hepatocytes, inflammatory cell infiltration and single-cell necrosis were observed on histopathological examination of the liver in TSOD mice. Salacia extract markedly improved these symptoms upon treatment. Based on the above results, it is concluded that Salacia extract has remarkable potential to prevent obesity and associated metabolic disorders including the development of metabolic syndrome.

    Full Text Available Abstract Childhood obesity has reached epidemic levels in developed countries. Twenty five percent of children in the US are overweight and 11% are obese. Overweight and obesity in childhood are known to have significant impact on both physical and psychological health. The mechanism of obesity development is not fully understood and it is believed to be a disorder with multiple causes. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. In general, overweight and obesity are assumed to be the results of an increase in caloric and fat intake. On the other hand, there are supporting evidence that excessive sugar intake by soft drink, increased portion size, and steady decline in physical activity have been playing major roles in the rising rates of obesity all around the world. Consequently, both over-consumption of calories and reduced physical activity are involved in childhood obesity. Almost all researchers agree that prevention could be the key strategy for controlling the current epidemic of obesity. Prevention may include primary prevention of overweight or obesity, secondary prevention or prevention of weight regains following weight loss, and avoidance of more weight increase in obese persons unable to lose weight. Until now, most approaches have focused on changing the behaviour of individuals in diet and exercise. It seems, however, that these strategies have had little impact on the growing increase of the obesity epidemic. While about 50% of the adults are overweight and obese in many countries, it is difficult to reduce excessive weight once it becomes established. Children should therefore be considered the priority population for intervention strategies. Prevention may be achieved through a variety of interventions targeting built environment, physical activity, and diet. Some of these potential strategies for intervention in children can be implemented by targeting preschool institutions, schools or after-school care services as natural setting for influencing the diet and physical activity. All in all, there is an urgent need to initiate prevention and treatment of obesity in children.

    Overweight or obesity has become a serious public health problem in the world, scientists are concentrating their efforts on exploring novel ways to treat obesity. Nowadays, the availabilities of bariatric surgery and pharmacotherapy have enhanced obesity treatment, but it should has support from diet, physical exercise and lifestyle modification, especially the functional food. Resistant starch, an indigestible starch, has been studied for years for its beneficial effects on regulating blood glucose level and lipid metabolism. The aim of this review is to summarize the effect of resistant starch on weight loss and the possible mechanisms. According to numerous previous studies it could be concluded that resistant starch can reduce fat accumulation, enhance insulin sensitivity, regulate blood glucose level and lipid metabolism. Recent investigations have focused on the possible associations between resistant starch and incretins as well as gut microbiota. Resistant starch seems to be a promising dietary fiber for the prevention or treatment of obesity and its related diseases. PMID:25966755

    Mothers with obesity or gestational diabetes mellitus have low circulating levels of adiponectin (ADN) and frequently deliver large babies with increased fat mass, who are susceptible to perinatal complications and to development of metabolic syndrome later in life. It is currently unknown if the inverse correlation between maternal ADN and fetal growth reflects a cause-and-effect relationship. We tested the hypothesis that ADN supplementation in obese pregnant dams improves maternal insulin sensitivity, restores normal placental insulin/mechanistic target of rapamycin complex 1 (mTORC1) signaling and nutrient transport, and prevents fetal overgrowth. Compared with dams on a control diet, female C57BL/6J mice fed an obesogenic diet before mating and throughout gestation had increased fasting serum leptin, insulin, and C-peptide, and reduced high-molecular-weight ADN at embryonic day (E) 18.5. Placental insulin and mTORC1 signaling was activated, peroxisome proliferator-activated receptor-? (PPAR?) phosphorylation was reduced, placental transport of glucose and amino acids in vivo was increased, and fetal weights were 29% higher in obese dams. Maternal ADN infusion in obese dams from E14.5 to E18.5 normalized maternal insulin sensitivity, placental insulin/mTORC1 and PPAR? signaling, nutrient transport, and fetal growth without affecting maternal fat mass. Using a mouse model with striking similarities to obese pregnant women, we demonstrate that ADN functions as an endocrine link between maternal adipose tissue and fetal growth by regulating placental function. Importantly, maternal ADN supplementation reversed the adverse effects of maternal obesity on placental function and fetal growth. Improving maternal ADN levels may serve as an effective intervention strategy to prevent fetal overgrowth caused by maternal obesity. PMID:26417088

    Low-income youth are at increased risk for excess weight gain. Although evidence-based prevention programs exist, successful adaptation to provide wide dissemination presents a challenge. Hip-Hop to Health (HH) is a school-based obesity prevention intervention that targets primarily preschool children of low-income families. In a large randomized controlled trial, HH was found to be efficacious for prevention of excessive weight gain. The Expanded Food and Nutrition Education Program (EFNEP) and the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) are USDA-funded nutrition education programs offered to low-income families, and may provide an ideal platform for the wide dissemination of evidence-based obesity prevention programs. A research-practice partnership was established in order to conduct formative research to guide the adaptation and implementation of HH through EFNEP and SNAP-Ed. We present the design and method of a comparative effectiveness trial that will determine the efficacy of HH when delivered by peer educators through these programs compared to the standard EFNEP and SNAP-Ed nutrition education (NE) curriculum. Results from this trial will inform larger scale dissemination. The dissemination of HH through government programs has the potential to increase the reach of efficacious obesity prevention programs that target low-income children and families. PMID:24952282

    Lund, Thomas BØker; SandØe, Peter

    2011-01-01

    The aim of this study was to investigate the Danish public’s support for publicly funded obesity treatment and prevention. It was also examined whether levels of support could be explained by dislike of obese people and / or the belief that those who are obese are personally responsible for their condition. A representative survey of members of the Danish public (N=1,141) was conducted using a web-based questionnaire. The survey was designed to assess attitudes to public funding for obesityrelated health care, and to investigate the impact, on those attitudes, of dislike of obese people, the perceived controllability of obesity, self-reported BMI, and additional attitudinal and sociodemographic characteristics. Public funding of some obesity treatments, such as weight-loss surgery, attracted only limited public support. A majority of the Danish public did support ‘softer’ treatment interventions and preventive initiatives. Attitudes to the treatment of obesity were clearly best predicted by the belief that individuals are personally responsible for their own obesity. Dislike of obese persons had no direct effect on the preference for collective treatment initiatives and only a small effect on support for publicly funded obesity prevention. The high level of disapproval for publicly funded obesity treatment should be cause for concern for decision makers aiming to ensure equal access to health care. Since it is the belief that obese people are personally responsible which explains this disapproval, strategies for challenging public opinion on this issue are discussed.

    Childhood obesity is a major concern for public health. There are multiple factors (e.g., genetic, social, and environmental) that contribute to unhealthy weight gain. Drawing from findings on "obesogenic environments" and core principles of preventive strategies to reduce health inequalities, this paper gives an overview of recent childhood prevention programs that target aspects of the physical environment ("environmental changes"). Out of the ten reviews we screened (including more than 300 studies), we identified very few that addressed aspects of the environment. We focus here on 14 programs that follow different approaches to environmental changes (e.g., access to/quality of playgrounds, changes in school cafeterias). Altering the environment offers opportunities for healthier behaviors and seems to be an effective strategy to prevent childhood obesity. However, the evaluation of those (mostly) multidimensional interventions does not allow drawing firm conclusions about the single effect of environmental changes. We conclude that obesity prevention programs should combine person-based and environmental approaches. PMID:25928754

    Prevention of obesity requires policies that work. In this Series paper, we propose a new way to understand how food policies could be made to work more effectively for obesity prevention. Our approach draws on evidence from a range of disciplines (psychology, economics, and public health nutrition) to develop a theory of change to understand how food policies work. We focus on one of the key determinants of obesity: diet. The evidence we review suggests that the interaction between human food preferences and the environment in which those preferences are learned, expressed, and reassessed has a central role. We identify four mechanisms through which food policies can affect diet: providing an enabling environment for learning of healthy preferences, overcoming barriers to the expression of healthy preferences, encouraging people to reassess existing unhealthy preferences at the point-of-purchase, and stimulating a food-systems response. We explore how actions in three specific policy areas (school settings, economic instruments, and nutrition labelling) work through these mechanisms, and draw implications for more effective policy design. We find that effective food-policy actions are those that lead to positive changes to food, social, and information environments and the systems that underpin them. Effective food-policy actions are tailored to the preference, behavioural, socioeconomic, and demographic characteristics of the people they seek to support, are designed to work through the mechanisms through which they have greatest effect, and are implemented as part of a combination of mutually reinforcing actions. Moving forward, priorities should include comprehensive policy actions that create an enabling environment for infants and children to learn healthy food preferences and targeted actions that enable disadvantaged populations to overcome barriers to meeting healthy preferences. Policy assessments should be carefully designed on the basis of a theory of change, using indicators of progress along the various pathways towards the long-term goal of reducing obesity rates.

    A well-resourced, comprehensive, population-based set of strategies is needed to attenuate and eventually reverse the current trends of increasing obesity prevalence now apparent in most countries. The Epidemiological Triad (host, vector, environment) has proven to be a robust model for other epidemics and is applied to obesity. Host-based strategies are primarily educational and these tend to be most effective among people with higher incomes and higher educational attainment. The main vectors for a high-energy intake are energy-dense foods and drinks and large portion sizes and, for low energy expenditure, machines that promote physical inactivity. Vector-based strategies that alter food formulation can have a significant impact, particularly through influencing common, high-volume foods. The increasingly 'obesogenic' environments are probably the main driving forces for the obesity epidemic. There are many environmental strategies that can influence the physical, economic, policy or socio-cultural environments, but the evidence base for these potentially powerful interventions is small. Children should be the priority population for interventions, and improving the general socio-economic conditions for disadvantaged, marginalized or poor population sectors is also a central strategy for obesity prevention. The key settings for interventions are schools, homes, neighbourhoods, primary health care services and communities. The key macroenvironments for interventions are the transport and infrastructure sector, the media and the food sector. PMID:12458974

  16. Childhood obesity: Determinants, evaluation, and prevention

    Full Text Available Childhood obesity is a grave issue, which needs to be addressed urgently because it leads to several medical and psychosocial problems in children. High prevalence is being increasingly reported in children from developing countries as well. The combination of our genetic propensity to store fat, the ready availability of calorie dense foods, and sedentary lifestyle promotes overweight. The child?s food environment at home and parental obesity are strong determinants. Urban poor in developed countries and urban rich in developing countries are both at risk. In developing countries, a number of beliefs passed down over generations are other important determinants. Evaluation includes assessing the child?s lifestyle, excluding weight-promoting medication history; poor linear growth needs endocrine evaluation; genetic syndromes should be considered if there are clinical pointers. Overweight children should be evaluated for hypertension, dyslipidemia, T2DM, and NAFLD. Therapeutic lifestyle changes targeting food habits and physical activity through parental participation and social support are the cornerstones of preventing childhood obesity. Active travel and play by making the built environment more accessible, ban on ?junk? food advertising, and effective health education through active participation of clinicians, school systems, and the media will go a long way in reversing anticipated trends in childhood obesity.

    Full Text Available Abstract Background Overweight and obesity have a dramatic negative impact on children's health not only during the childhood but also throughout the adult life. Preventing the development of obesity in children is therefore a world-wide health priority. There is an obvious urge for sustainable and evidenced-based interventions that are suitable for families with young children, especially for families with overweight or obese parents. We have developed a prevention program, Early STOPP, combating multiple obesity-promoting behaviors such unbalanced diet, physical inactivity and disturbed sleeping patterns. We also aim to evaluate the effectiveness of the early childhood obesity prevention in a well-characterized population of overweight or obese parents. This protocol outlines methods for the recruitment phase of the study. Design and methods This randomized controlled trial (RCT targets overweight and/or obese parents with infants, recruited from the Child Health Care Centers (CHCC within the Stockholm area. The intervention starts when infants are one year of age and continues until they are six and is regularly delivered by a trained coach (dietitian, physiotherapist or a nurse. The key aspects of Early STOPP family intervention are based on Swedish recommendations for CHCC, which include advices on healthy food choices and eating patterns, increasing physical activity/reducing sedentary behavior and regulating sleeping patterns. Discussion The Early STOPP trial design addresses weaknesses of previous research by recruiting from a well-characterized population, defining a feasible, theory-based intervention and assessing multiple measurements to validate and interpret the program effectiveness. The early years hold promise as a time in which obesity prevention may be most effective. To our knowledge, this longitudinal RCT is the first attempt to demonstrate whether an early, long-term, targeted health promotion program focusing on healthy eating, physical activity/reduced sedentary behaviors and normalizing sleeping patterns could be effective. If proven so, Early STOPP may protect children from the development of overweight and obesity.

    By 2002, China's prevalence of overweight and obesity among adults was 18.9 and 2.9%, respectively. The replacement of traditional Chinese diet with 'Western diet', major declines in all phases of activity and increased sedentary activity are cited as the main reasons explaining the rapid increase in overweight and obesity, which bring major economic and health costs. The Nutrition Improvement Work Management Approach was released in 2010. Overweight and obesity prevention-related policies were added to national planning for disease prevention and control. The Guidelines for Prevention and Control of Overweight and Obesity of Chinese Adults and the School-age Children and Teenagers Overweight and Obesity Prevention and Control Guidelines in China were promulgated in 2003 and 2007, respectively. Few education programmes have been implemented. Selected academic intervention research projects dominate with a focus on reducing child obesity and promoting healthier diets; increasing physical activity and reducing sedentary time; and facilitating changes in family, school, social and cultural environments. Intervention samples are small and have not addressed the increasing rates of obesity throughout the entire population. Government provision of effective policy measures, multisectoral cooperation and increasing corporate social responsibility are keys to curbing the trend towards overweight and obesity in China.

    Public mobilisation is needed to enact obesity-prevention policies and to mitigate reaction against their implementation. However, approaches in public health focus mainly on dialogue between public health professionals and political leaders. Strategies to increase popular demand for obesity-prevention policies include refinement and streamlining of public information, identification of effective obesity frames for each population, strengthening of media advocacy, building of citizen protest and engagement, and development of a receptive political environment with change agents embedded across organisations and sectors. Long-term support and investment in collaboration between diverse stakeholders to create shared value is also important. Each actor in an expanded coalition for obesity prevention can make specific contributions to engaging, mobilising, and coalescing the public. The shift from a top-down to a combined and integrated bottom-up and top-down approach would need an overhaul of current strategies and reprioritisation of resources. PMID:25703113

    The overweight and obesity epidemic among children and adolescents in the United States continues to worsen, with notable racial, ethnic, and socioeconomic disparities. Risk factors for pediatric obesity include genetics; environmental and neighborhood factors; increased intake of sugar-sweetened beverages (SSBs), fast-food, and processed snacks; decreased physical activity; shorter sleep duration; and increased personal, prenatal, or family stress. Pediatricians can help prevent obesity by measuring body mass index at least yearly and providing age- and development-appropriate anticipatory guidance to families. Public policies and environmental interventions aim to make it easier for children to make healthy nutrition and physical activity choices. Interventions focused on family habits and parenting strategies have also been successful at preventing or treating childhood obesity. PMID:26318950

    Full Text Available BACKGROUND: Prevention of childhood obesity is an international public health priority given the significant impact of obesity on acute and chronic diseases, general health, development and well-being. The international evidence base for strategies that governments, communities and families can im [...] plement to prevent obesity, and promote health, has been accumulating but remains unclear. OBJECTIVE: This review primarily aims to update the previous Cochrane review of childhood obesity prevention research and determine the effectiveness of evaluated interventions intended to prevent obesity in children, assessed by change in Body Mass Index (BMI). Secondary aims were to examine the characteristics of the programs and strategies to answer the questions "What works for whom, why and for what cost?" METHODS: Search methods: The searches were re-run in CENTRAL, MEDLINE, EMBASE, PsychINFO and CINAHL in March 2010 and searched relevant websites. Non-English language papers were included and experts were contacted. Selection criteria: The review includes data from childhood obesity prevention studies that used a controlled study design (with or without randomisation). Studies were included if they evaluated interventions, policies or programs in place for twelve weeks or more. If studies were randomized at a cluster level, six clusters were required. Data collection and analysis: Two review authors independently extracted data and assessed the risk of bias of included studies. Data was extracted on intervention implementation, cost, equity and outcomes. Outcome measures were grouped according to whether they measured adiposity, physical activity (PA)-related behaviours or diet-related behaviours. Adverse outcomes were recorded. A meta-analysis was conducted using available BMI or standardized BMI (zBMI) score data with subgroup analysis by age group (0-5, 6-12, 13-18 years, corresponding to stages of developmental and childhood settings). MAIN RESULTS: This review includes 55 studies (an additional 36 studies found for this update). The majority of studies targeted children aged v 6-12 years. The meta-analysis included 37 studies of 27,946 children and demonstrated that programmes were effective at reducing adiposity, although not all individual interventions were effective, and there was a high level of observed heterogeneity (I2 = 82%). Overall, children in the intervention group had a standardised mean difference in adiposity (measured as BMI or zBMI) of -0.15kg/m2 (95% confidence interval (CI): -0.21 to -0.09). Intervention effects by age subgroups were -0.26kg/m2 (95% CI -0.53 to 0.00) (0- 5 years), - 0.15 kg/m2 (95% CI -0.23 to -0.08) (6-12 years), and -0.09 kg/m2 (95% CI -0.20 to 0.03) (13-18 years). Heterogeneity was apparent in all three age groups and could not explained by randomisation status or the type, duration or setting of the intervention. Only eight studies reported on adverse effects and no evidence of adverse outcomes such as unhealthy dieting practices, increased prevalence of underweight or body image sensitivities was found. Interventions did not appear to increase health inequalities although this was examined in fewer studies. AUTHORS' CONCLUSIONS: We found strong evidence to support beneficial effects of child obesity prevention programmes on BMI, particularly for programmes targeted to children aged six to 12 years. However, given the unexplained heterogeneity and the likelihood of small study bias, these findings must be interpreted cautiously. A broad range of programme components were used in these studies and whilst it is not possible to distinguish which of these components contributed most to the beneficial effects observed, our synthesis indicates the following to be promising policies and strategies: school curriculum that includes healthy eating, physical activity and body image; increased sessions for physical activity and the development of fundamental movement skills throughout the school week; improvements in nutritional quality of the food supply in schools; envir

    School-based childhood obesity prevention programs have grown in response to reductions in child physical activity (PA), increased sedentariness, poor diet, and soaring child obesity rates. Multiple systematic reviews indicate school-based obesity prevention/treatment interventions are effective, yet few studies have examined the school nurse role in obesity interventions. Building on a previous study, this study examines a refined health messaging (Let's Go 5-2-1-0) program delivered to fourth and fifth graders (n = 72) by a school nurse with reinforcement on-site health coaching by senior nursing students. Two nursing schools and two elementary schools participated. Measures of PA, body mass index percentile, and self-reported health habits were collected at baseline (School A, September 2009 and School B, January 2010) and end of year (April 2010 for both schools). Findings included statistically significant increases in PA levels and improvements in child-reported health habits. School nurses can influence obesity prevention. Further research on adoption of school nurse-led obesity interventions is warranted. PMID:25747899

    The increased prevalence of childhood overweight and obesity is not unique to industrialized societies; dramatic increases are occurring in urbanized areas of developing countries. In light of the consensus that obesity is a significant public health concern and that many weight-loss interventions have been unsuccessful in the long term, an exploration of food patterns that are beneficial in the primary prevention of obesity is warranted. The focus of this article is to review the relation between vegetarian diets and obesity, particularly as they relate to childhood obesity. Epidemiologic studies indicate that vegetarian diets are associated with a lower body mass index (BMI) and a lower prevalence of obesity in adults and children. A meta-analysis of adult vegetarian diet studies estimated a reduced weight difference of 7.6 kg for men and 3.3 kg for women, which resulted in a 2-point lower BMI (in kg/m(2)). Similarly, compared with nonvegetarians, vegetarian children are leaner, and their BMI difference becomes greater during adolescence. Studies exploring the risk of overweight and food groups and dietary patterns indicate that a plant-based diet seems to be a sensible approach for the prevention of obesity in children. Plant-based diets are low in energy density and high in complex carbohydrate, fiber, and water, which may increase satiety and resting energy expenditure. Plant-based dietary patterns should be encouraged for optimal health and environmental benefits. Food policies are warranted to support social marketing messages and to reduce the cultural and economic forces that make it difficult to promote plant-based dietary patterns. PMID:20237136

    The global obesity epidemic is associated with a sedentary lifestyle and diets rich in high-fat, high-energy foods. The potential role of fruit in preventing overweight and obesity is related to their relatively low energy density, high content of dietary fibre, and associated increasing satiety effect. The physical disruption of fruit is of considerable importance for satiety, as shown in studies in which fruit juices were less satisfying compared to sugar-equivalent intakes of purees and whole fruits. The potential role of fruit in the prevention of overweight and obesity may be connected to the dietary pattern of fruit intake, and with the possibility that fruit intake may substitute for other, more energy-dense foods. The majority of human prospective cohort studies in adults suggest a preventive effect of increased fruit intake oil body weight gain; whereas a few studies have suggested the opposite, in the case of fruit juices. Prospective studies oil children are few and inconclusive, but suggest associations between fruit intake and body weight that are related to the initial nutritional status. In behavioural intervention studies, subjects are often advised to undergo several changes towards a healthy diet and lifestyle, making it impossible to quantity the specific effect of fruit intake oil body weight. In the few available intervention studies in adults, the Study period was often too short to allow measures of body weight changes, and studies oil overweight or obese subjects may not apply to subjects of normal weight. Intervention studies targeted at school children showed that such schemes call be effective in increasing fruit intake, but a convincing role for increased fruit intake in the prevention of overweight and obesity in children still needs to be established. The present evidence suggests that fruit consumption has a potential role in the prevention of overweight and obesity.

This constitutes a "market failure," signaling the need for government interventions with policies, programs, and social marketing. Population prevention strategies are critical, and children and adolescents should be the priority populations. Food marketing to children is a central policy issue for governments to address, and comprehensive regulations are needed to provide substantive protection for children. Community-based intervention programs show some real promise in reducing childhood obesity, but the 2 big challenges ahead are to ensure that there is substantial ongoing funding so that the community capacity to promote healthy weights can be scaled up to a national level and to ensure that policies are in place to support these efforts. The social and cultural shifts that support healthy eating and physical activity occur differentially, and special efforts are needed to reduce the socioeconomic gradients associated with childhood obesity. A positive public health approach encompassing environmental, regulatory, sociocultural, and educational strategies offer the best chance of reducing obesity without increasing disordered eating patterns.

    Government and societal efforts to combat obesity are aimed at prevention, although there is a generation for whom excess weight is the rule rather than the exception. Although measures to prevent a worsening of the current epidemic are important, management of obesity must also be prioritised. Obesity management is beset with problems ranging from attitudinal to clinical and pharmacological, and the individualisation of therapy.

    Over the years, obesity prevention has been a broadly studied subject by both academicians and practitioners. It is one of the most serious public health issue as it can cause numerous chronic health and psychosocial problems. Research is needed to suggest a population-based strategy for obesity prevention. In the academic environment, the importance of obesity prevention has triggered various problem solving approaches. A good obesity prevention model, should comprehend and cater all complex and dynamics issues. Hence, the main purpose of this paper is to discuss the qualitative and quantitative approaches on obesity prevention study and to provide an extensive literature review on various recent modelling techniques for obesity prevention. Based on these literatures, the comparison of both quantitative and qualitative approahes are highlighted and the justification on the used of system dynamics technique to solve the population of obesity is discussed. Lastly, a potential framework solution based on system dynamics modelling is proposed.

    Obesity prevalence in the Brazilian adult population is 12.5% among men and 16.9% among women. Obesity control has been a subject of concern in Brazilian health policies since the publication of the National Food and Nutrition Policy in 1999. The initiatives include a comprehensive national intersectorial plan for obesity prevention and control focused on confronting its social and environmental causes, development of a food and nutrition education framework aimed at intersectorial public policies in the food and nutritional security field, promotion and provision of healthy food in school environments (linked to family farming), structuring nutrition actions in primary healthcare in the national healthcare system, promoting community physical activity, food regulation and control, and encouragement of public participation and food control. We conclude that several initiatives have been developed in Brazil to deal with the challenge of implementing an intergovernmental, intersectorial response to reverse the rising overweight and obesity rates. The success of this response will depend on a governance model that promotes joint and integrated action by different sectors and active participation of society to consolidate the actions, places and laws that protect health and promote healthy lifestyles.

    Cellular telephony has become a bright example of co-evolution of human society and information technology. This trend has also been reflected in health care and health promotion projects which included cell phones in data collection and communication chain. While many successful projects have been realized, the review of phone-based data collection techniques reveals that the existing technologies do not completely address health promotion research needs. The paper presents approaches which close this gap by extending existing versatile platforms. The messaging systems are designed for a health-promotion research to prevent obesity and obesity-related health disparities among low-income Latino adolescent girls. Messaging and polling mechanisms are used to communicate and automatically process response data for the target constituency. Preliminary survey data provide an insight on phone availability and technology perception for the study group.

    High doses of rapamycin, an antiaging agent, can prevent obesity in mice on high fat diet (HFD). Obesity is usually associated with hyperinsulinemia. Here, we showed that rapamycin given orally, at doses that did not affect weight gain in male mice on HFD, tended to decrease fasting insulin levels. Addition of resveratrol, which alone did not affect insulin levels, potentiated the effect of rapamycin, so that the combination decreased obesity and prevented hyperinsulinemia. Neither rapamycin ...

    2007-07-01

    Full Text Available IntroductionBecause of the public’s growing awareness of the childhood obesity epidemic, health policies that address obesogenic environments by encouraging healthy eating and increased physical activity are gaining more attention. However, there has been little systematic examination of state policy efforts. This study identified and described state-level childhood obesity prevention legislation introduced and adopted from 2003 through 2005 and attempted to identify regional geographic patterns of introduced legislation.MethodsA scan of legislation from all 50 states identified 717 bills and 134 resolutions that met study inclusion criteria. Analyses examined patterns in the introduction and adoption of legislation by time, topic area, and geography.ResultsOverall, 17% of bills and 53% of resolutions were adopted. The amount of legislation introduced and adopted increased from 2003 through 2005. The topic areas with the most introduced legislation were school nutrition standards and vending machines (n = 238; physical education and physical activity (n = 191; and studies, councils, or task forces (n = 110. Community-related topic areas of walking and biking paths (37%, farmers’ markets (36%, and statewide initiatives (30% had the highest proportion of bills adopted, followed by model school policies (29% and safe routes to school (28%. Some regional geographic patterns in the introduction of legislation were observed. There was no statistical association between state-level adult obesity prevalence and introduction of legislation.ConclusionPublic health and health policy practitioners can use this information to improve advocacy efforts and strengthen the political climate for establishing childhood obesity prevention legislation within state governments. Expanded surveillance (including standardized identification and cataloging of introduced and adopted legislation will enhance the ability to assess progress and identify effective approaches. Future policy research should examine determinants, implementation, and effectiveness of legislation to prevent childhood obesity.

Mexico currently has few innovative and comprehensive experiences to help curb the growth of this serious public health problem. Therefore, the aim of this study is to assess the effectiveness of a nutrition and physical activity strategy, called "Nutrition on the Go" ("nutrición en movimiento" in maintaining the BMI values of school children in the State of Mexico. Methods A two-stage cluster trial was carried out. Sixty schools were selected in the State of Mexico, of which 30 were randomly assigned to the intervention group (IG and 30 to the control group (CG. A total of 1020 fifth grade school children participated. The intervention strategy aimed to decrease the energy content of school breakfasts and include fruits and vegetables, as well as increase physical activity and the consumption of water during the time spent at school. The strategy was implemented over a 6-month period. Results The estimated probability (EP of obesity between baseline and the final stage for the IG decreased 1% (Initial EP = 11.8%, 95%CI 9.0, 15.2, final EP = 10.8, 95%CI 8.4, 13. For the CG, the probability increased 0.9% (baseline EP = 10.6%; 95%CI 8.1, 13.7; final EP = 11.5, 95%CI 9.0, 14.6. The interaction between the intervention and the stage is the average odd time corrected treatment effect, which is statistically significant (p = 0.01 (OR = 0.68, 95%CI 0.52, 091. This represents the interaction between intervention and stage, which is highly significant (p = 0.01 (OR = 0.68; 95%CI 0.52, 091. In addition, girls had a protective effect on obesity (OR = 0.56; 95%CI 0.39, 0.80. Conclusions The intervention strategy is effective in maintaining the BMI of school children.

  15. Nutraceutical Approach for Preventing Obesity-Related Colorectal and Liver Carcinogenesis

    Directory of Open Access Journals (Sweden)

    Hisataka Moriwaki

    2012-01-01

    Full Text Available Obesity and its related metabolic abnormalities, including insulin resistance, alterations in the insulin-like growth factor-1 (IGF-1/IGF-1 receptor (IGF-1R axis, and the state of chronic inflammation, increase the risk of colorectal cancer (CRC and hepatocellular carcinoma (HCC. However, these findings also indicate that the metabolic disorders caused by obesity might be effective targets to prevent the development of CRC and HCC in obese individuals. Green tea catechins (GTCs possess anticancer and chemopreventive properties against cancer in various organs, including the colorectum and liver. GTCs have also been known to exert anti-obesity, antidiabetic, and anti-inflammatory effects, indicating that GTCs might be useful for the prevention of obesity-associated colorectal and liver carcinogenesis. Further, branched-chain amino acids (BCAA, which improve protein malnutrition and prevent progressive hepatic failure in patients with chronic liver diseases, might be also effective for the suppression of obesity-related carcinogenesis because oral supplementation with BCAA reduces the risk of HCC in obese cirrhotic patients. BCAA shows these beneficial effects because they can improve insulin resistance. Here, we review the detailed relationship between metabolic abnormalities and the development of CRC and HCC. We also review evidence, especially that based on our basic and clinical research using GTCs and BCAA, which indicates that targeting metabolic abnormalities by either pharmaceutical or nutritional intervention may be an effective strategy to prevent the development of CRC and HCC in obese individuals.

    Full Text Available Background: In spite of the numerous chronic diseases that have been linked to obesity, studies focusing on the awareness regarding causes, consequences and strategies to prevent and control of obesity among women are lacking in the literature, especially in developing countries such as India, where obesity is culturally accepted and nurtured and women bearded the highest weight gain in the recent decade. Objective: We explored the awareness regarding causes, consequences and preventive measures of obesity among 325 ever-married aged 20-54 years women with different levels of body mass index (BMI in the national capital territory of Delhi representing urban India. Materials and Methods: A population based follow-up survey of women systematically selected from the second round of National Family Health Survey (NFHS-2, 1998-99 samples who were re-interviewed after four years in 2003. As a part of qualitative data collection, the respondents were asked to free list open-ended questions on causes, consequences and preventive measures of obesity. Responses were analyzed through Anthropac software package. Results: Over eating was reported as the most important cause of obesity by normal and overweight women whereas obese women reported fried food consumption as the most important cause of weight gain. A few women from each group reported changing lifestyle as a cause of obesity. Also, there were lots of misconceptions about the cause of obesity among women (such as no tension in life, more tension, happiness, constipation, problem in Delhi's water etc.. In terms of the consequences of obesity, the participants were well aware of the common physical consequences. Normal and obese women reported breathlessness as the most important consequence whereas overweight women reported problem in standing and sitting. Regarding preventive measures, overweight and obese women reported 'walking' as most important preventive measure of obesity whereas normal women reported 'doing exercise'. In addition, 'dieting' was reported as the next important preventive measures of obesity by all groups of women. Conclusion: Our study of a fairly large, community-based sample of women has shown that women were aware of the complex nature of obesity in terms of causes, consequences and a range of potential solutions. The findings are important for public health interventions in obesity care in India. Implementation of health promotion and health education in the community should use effective school education and mass media programme to raise more awareness of the causes, consequences and preventive measures and hammer misconceptions, to combat the growing level of obesity among Indian women.

    A dramatic increase in childhood overweight/obesity has been recognized globally over the past 50?years. This observed increase may reflect genetic, as well as psychological, environmental, and socio-cultural influences. In the first part of this review, we present an updated summary of the psychosocial factors associated with this change and discuss possible ways in which they operate. Among these factors, lower socio economic status (in both industrialized and non-industrialized countries), being female, belonging to a minority group, and being exposed to adverse life events may all be associated with a greater risk of childhood overweight/obesity. These influences may be mediated via a variety of mechanisms, in particular above-average food intake of low nutritional quality and reduction in physical activity. Other important psychosocial mediators include the influence of the family and peer environment, and exposure to the media. In the second part of the review, we discuss the potential of psychosocial prevention programs to intervene in the processes involved in the rise of childhood overweight/obesity. Two points are emphasized. First, prevention programs should be multidisciplinary, combining the knowledge of experts from different professions, and taking into consideration the important role of the family environment and relevant influential social organizations, particularly school. Second, effective change is unlikely to occur without large-scale programs carried out on a public policy level. PMID:25133140

    Overweight and obesity in children are recognized as a major health problem. The ToyBox-intervention was developed with the aim of preventing obesity in pre-schoolers. Because it is increasingly important to inform policy makers not only on the effects of prevention interventions, but also on their costs and cost-effectiveness, our purpose was to establish a method to estimate the cost-effectiveness of the ToyBox-intervention. In order to estimate the long-term impact of the ToyBox-intervention on health and societal costs, extrapolations of the intervention effect will be conducted to predict children's weight status (based on the body mass index) at adult age. Effects of the adult weight status on the prevalence of obesity-related complications will be modelled through a Markov model, with a total time horizon of 70 years and a cycle length of 1 year. The model will be conducted in six European countries participating in the ToyBox-intervention, based on country-specific economic and epidemiological data. This study describes the methodological rationale and implementation of an analytic model to examine the cost-effectiveness of the ToyBox-intervention for six European countries, in order to inform decision-makers on the value for money of this intervention in the prevention of obesity in pre-schoolers.

    Neumark-Sztainer, Dianne

    2012-12-01

    Weight-related problems, including unhealthy weight control behaviors, binge eating, overweight and obesity, and eating disorders, are prevalent in youth. Furthermore, many young people exhibit more than one of these problems. Therefore, it is essential to consider how to simultaneously work toward the prevention of a broad range of weight-related problems in youth. Dieting, body dissatisfaction, weight talk, and weight-related teasing are commonly addressed risk factors within eating disorder prevention interventions, whereas low levels of physical activity and high intakes of foods high in fat and sugar are commonly addressed within interventions aimed at obesity prevention. Empirical data to be presented in this article demonstrate why risk factors such as dieting and body dissatisfaction, which are typically addressed within the eating disorder field, need to also be addressed within the obesity field. Although dieting and body dissatisfaction strongly predict weight gain over time, these findings are not always taken into account in the design of obesity interventions for youth. Possible reasons as to why risk factors such as dieting, body dissatisfaction, and weight stigmatization may be not adequately addressed within interventions addressing obesity are discussed. Suggestions for how physicians and other nonphysician clinicians might link messages from the fields of both eating disorders and obesity into their work with youth are provided. Finally, the potential for work on mindfulness and yoga to decrease risk factors for both eating disorders and obesity are explored. PMID:23437686

    Full Text Available Still more alarming obesity studies show in fact that it is largely due to incorrect diet and lifestyle. For suitable alternative for prevention of this disease are now considered cereal foods, mainly based on increased fiber content. The importance of dietary fiber for human organism consist primarily in its protective function before civilization diseases. It has beneficial effects on digestive physiology and it is therefore an important factor in the prevention of obesity, but also other diseases. Fiber consumption in developed countries is low and it is below the lower limit of the recommended dose. Slovaks per day take only 10-12 g of fiber, which represents only 47% of the recommended dose. Recent large-scale epidemiological studies have shown that regular consumption of wholegrain cereals can reduce the risk of heart disease and certain cancers by 30 percent. One of the factors that increase the functionality of foods is the so-called indigestible resistant starch. For its the positive impact on the physiology of digestion is referred to as prebiotics new generation of dietary fiber. The increasing availability of tasty, whole grain products rich in fiber could be health benefits. doi:10.5219/76

Although body mass has a positive effect on bone formation, whether the mass derived from an obesity condition or excessive fat accumulation is beneficial to bone remains controversial. The underline pathophysiological relationship between obesity and bone is complex and continues to be an active research area. Recent data from epidemiological and animal studies strongly support that fat accumulation is detrimental to bone mass. To our knowledge, obesity possibly affects bone metabolism through several mechanisms. Because both adipocytes and osteoblasts are derived from a common multipotential mesenchymal stem cell, obesity may increase adipocyte differentiation and fat accumulation while decrease osteoblast differentiation and bone formation. Obesity is associated with chronic inflammation. The increased circulating and tissue proinflammatory cytokines in obesity may promote osteoclast activity and bone resorption through modifying the receptor activator of NF-?B (RANK/RANK ligand/osteoprotegerin pathway. Furthermore, the excessive secretion of leptin and/or decreased production of adiponectin by adipocytes in obesity may either directly affect bone formation or indirectly affect bone resorption through up-regulated proinflammatory cytokine production. Finally, high-fat intake may interfere with intestinal calcium absorption and therefore decrease calcium availability for bone formation. Unraveling the relationship between fat and bone metabolism at molecular level may help us to develop therapeutic agents to prevent or treat both obesity and osteoporosis. Obesity, defined as having a body mass index ? 30 kg/m2, is a condition in which excessive body fat accumulates to a degree that adversely affects health 1. The rates of obesity rates have doubled since 1980 2 and as of 2007, 33% of men and 35% of women in the US are obese 3. Obesity is positively associated to many chronic disorders such as hypertension, dyslipidemia, type 2 diabetes mellitus, coronary heart disease, and certain cancers 456. It is estimated that the direct medical cost associated with obesity in the United States is ~$100 billion per year 7. Bone mass and strength decrease during adulthood, especially in women after menopause 8. These changes can culminate in osteoporosis, a disease characterized by low bone mass and microarchitectural deterioration resulting in increased bone fracture risk. It is estimated that there are about 10 million Americans over the age of 50 who have osteoporosis while another 34 million people are at risk of developing the disease 9. In 2001, osteoporosis alone accounted for some $17 billion in direct annual healthcare expenditure. Several lines of evidence suggest that obesity and bone metabolism are interrelated. First, both osteoblasts (bone forming cells and adipocytes (energy storing cells are derived from a common mesenchymal stem cell 10 and agents inhibiting adipogenesis stimulated osteoblast differentiation 111213 and vice versa, those inhibiting osteoblastogenesis increased adipogenesis 14. Second, decreased bone marrow osteoblastogenesis with aging is usually accompanied with increased marrow adipogenesis 1516. Third, chronic use of steroid hormone, such as glucocorticoid, results in obesity accompanied by rapid bone loss 1718. Fourth, both obesity and osteoporosis are associated with elevated oxidative stress and increased production of proinflammatory cytokines 1920. At present, the mechanisms for the effects of obesity on bone metabolism are not well defined and will be the focus of this review.

    Obesity is increasing worldwide with the Pacific region having the highest prevalence among adults. The most common precursor of adult obesity is adolescent obesity making this a critical period for prevention. The Pacific Obesity Prevention in Communities project was a four-country project (Fiji, Tonga, New Zealand and Australia) designed to prevent adolescent obesity. This paper overviews the project and the methods common to the four countries. Each country implemented a community-based intervention programme promoting healthy eating, physical activity and healthy weight in adolescents. A community capacity-building approach was used, with common processes employed but with contextualized interventions within each country. Changes in anthropometric, behavioural and perception outcomes were evaluated at the individual level and school environments and community capacity at the settings level. The evaluation tools common to each are described. Additional analytical studies included economic, socio-cultural and policy studies. The project pioneered many areas of obesity prevention research: using multi-country collaboration to build research capacity; testing a capacity-building approach in ethnic groups with very high obesity prevalence; costing complex, long-term community intervention programmes; systematically studying the powerful socio-cultural influences on weight gain; and undertaking a participatory, national, priority-setting process for policy interventions using simulation modelling of cost-effectiveness of interventions.

    We developed a theoretical framework to organize obesity prevention interventions by their likely impact on the socioeconomic gradient of weight. The degree to which an intervention involves individual agency versus structural change influences socioeconomic inequalities in weight. Agentic interventions, such as standalone social marketing, increase socioeconomic inequalities. Structural interventions, such as food procurement policies and restrictions on unhealthy foods in schools, show equal or greater benefit for lower socioeconomic groups. Many obesity prevention interventions belong to the agento-structural types of interventions, and account for the environment in which health behaviors occur, but they require a level of individual agency for behavioral change, including workplace design to encourage exercise and fiscal regulation of unhealthy foods or beverages. Obesity prevention interventions differ in their effectiveness across socioeconomic groups. Limiting further increases in socioeconomic inequalities in obesity requires implementation of structural interventions. Further empirical evaluation, especially of agento-structural type interventions, remains crucial. PMID:25121810

    Motivational interviewing is a counseling method used to bring about behavior change; its application by school nurses for preventing obesity in children is still new. This study, based on in-depth interviews with 12 school nurses, shows how school nurses adapted motivational interviewing and integrated it into their daily practice along with other methods they knew from the past. Three dilemmas for school nurses were revealed: when the child was severely overweight and the parents did not perceive this as a problem, when the child and the parents were at different stages of motivation to change, and when applying an individualized approach such as motivational interviewing for preventing a complex societal problem, in this instance obesity. The study raises an important issue to consider, with implications for school nursing and obesity prevention: motivational interviewing as either a counseling method or a prevention strategy.

Sedentary lifestyle and consumption of calorie-dense foods of low nutritional value are speculated to be two of the most important etiological factors responsible for escalating rate of childhood overweight in developing nations. To tackle the childhood obesity epidemic we require comprehensive multidisciplinary evidence-based interventions. Some suggested strategies for childhood obesity prevention and management include increasing physical activity, reducing sedentary time including television viewing, personalized nutrition plans for very obese kids, co-curriculum health education which should be implemented in schools and counseling for children and their parents. In developing countries like India we will need practical and cost-effective community-based strategies with appropriate policy changes in order to curb the escalating epidemic of childhood obesity.

  14. Obesity prevention: the role of policies, laws and regulations.

    2008-01-01

    The commercial drivers of the obesity epidemic are so influential that obesity can be considered a robust sign of commercial success - consumers are buying more food, more cars and more energy-saving machines. It is unlikely that these powerful economic forces will change sufficiently in response to consumer desires to eat less and move more or corporate desires to be more socially responsible. When the free market creates substantial population detriments and health inequalities, government policies are needed to change the ground rules in favour of population benefits.Concerted action is needed from governments in four broad areas: provide leadership to set the agenda and show the way; advocate for a multi-sector response and establish the mechanisms for all sectors to engage and enhance action; develop and implement policies (including laws and regulations) to create healthier food and activity environments, and; secure increased and continued funding to reduce obesogenic environments and promote healthy eating and physical activity.Policies, laws and regulations are often needed to drive the environmental and social changes that, eventually, will have a sustainable impact on reducing obesity. An 'obesity impact assessment' on legislation such as public liability, urban planning, transport, food safety, agriculture, and trade may identify 'rules' which contribute to obesogenic environments. In other areas, such as marketing to children, school food, and taxes/levies, there may be opportunities for regulations to actively support obesity prevention. Legislation in other areas such as to reduce climate change may also contribute to obesity prevention ('stealth interventions'). A political willingness to use policy instruments to drive change will probably be an early hallmark of successful obesity prevention. PMID:18534000

    Endothelial dysfunction precedes atherosclerosis and represents an important link between obesity and cardiovascular events. Strategies designed to prevent endothelial dysfunction may therefore reduce the cardiovascular complications triggered by obesity. We tested the hypothesis that deficiency of P-selectin glycoprotein ligand-1 (Psgl-1) would improve the endothelial dysfunction associated with obesity. Psgl-1-deficient (Psgl-1(-/-)) and wild-type (Psgl-1(+/+)) mice were fed standard chow or a high-fat, high-sucrose diet (diet-induced obesity [DIO]) for 10 weeks. DIO increased mesenteric perivascular adipose tissue (mPVAT) macrophage content and vascular oxidative stress in Psgl-1(+/+) mice but not in Psgl-1(-/-) mice. Pressure myography using mesenteric arteries demonstrated that relaxation responses to acetylcholine were significantly impaired in DIO Psgl-1(+/+) mice, whereas DIO Psgl-1(-/-) mice were protected from endothelial dysfunction with similar relaxation responses to Psgl-1(+/+) or Psgl-1(-/-) mice fed standard chow. The superoxide scavenger 4-hydroxy-2,2,6,6-tetramethylpiperidinyloxy (TEMPOL) partially recovered impaired endothelial function induced by DIO. A neutralizing Psgl-1 antibody was also effective in preventing endothelial dysfunction and reducing mPVAT macrophage content induced by DIO. These results indicate that obesity in mice leads to PVAT inflammation and endothelial dysfunction that is prevented by Psgl-1 deficiency. Psgl-1 inhibition may be a useful treatment strategy for targeting vascular disease associated with obesity. PMID:22891216

    Obesity is currently a global public health problem. Obesity in early life increases the risk of long-term energy imbalance and adult obesity and its comorbidities, type 2 diabetes, and cardiovascular disease. Since infancy and childhood are critical periods for the adoption of food preferences and physical activity, prevention strategies must intervene in these early periods to promote healthy habits and reduce risk behaviors. Trends in the prevalence of childhood obesity and overweight in Spain have continuously increased in the last three decades. Obesity and overweight currently affect 15 and 20% of Spanish children, respectively, and these percentages are among the highest in Europe. Childhood obesity is determined by social and economic factors pertaining to sectors other than the health system, such as advertising, the built environment, education and the school environment, transportation and the food environment. Following the Health in All Policies (HiAP) approach, the authors identified a series of multisector policy changes that may help to prevent and control the current rising trend of childhood obesity in Spain. The HiAP approach acknowledges that social factors including socioeconomic status, gender differences and the work-life balance are important to develop effective policy changes in the prevention of childhood obesity. A key to success in the prevention of childhood obesity in Spain through policy changes will depend on the ability to establish a policy with the explicit and primary goal of improving health outcomes, despite the anticipated resistance from various sectors and stakeholders.

  1. Endostatin Prevents Dietary-Induced Obesity by Inhibiting Adipogenesis and Angiogenesis.

    Endostatin is a well-known angiogenesis inhibitor. Although angiogenesis has been considered as a potential therapeutic target of obesity, the inhibitory effect of endostatin on adipogenesis and dietary-induced obesity has never been demonstrated. Adipogenesis plays a critical role in controlling adipocyte cell number, body weight, and metabolic profile in a homeostatic state. Here we reveal that endostatin inhibits adipogenesis and dietary-induced obesity. The antiadipogenic mechanism of endostatin lies in its interaction with Sam68 RNA-binding protein in the nuclei of preadipocytes. This interaction competitively impairs the binding of Sam68 to intron 5 of mammalian target of rapamycin (mTOR), causing an error in mTOR transcript. This consequently decreases the expression of mTOR, results in decreased activities of the mTOR complex 1 pathway, and leads to defects in adipogenesis. Moreover, our findings demonstrate that the antiangiogenic function of endostatin also contributes to its obesity-inhibitory activity. Through the combined functions on adipogenesis and angiogenesis, endostatin prevents dietary-induced obesity and its related metabolic disorders, including insulin resistance, glucose intolerance, and hepatic steatosis. Thus, our findings reveal that endostatin has a potential application for antiobesity therapy and the prevention of obesity-related metabolic syndromes. PMID:25605807

    Full Text Available Abstract Background Many unhealthy dietary and physical activity habits that foster the development of obesity are established by the age of five. Presently, approximately 70 percent of children in the United States are currently enrolled in early childcare facilities, making this an ideal setting to implement and evaluate childhood obesity prevention efforts. We describe here the methods for conducting an obesity prevention randomized trial in the child care setting. Methods/design A randomized, controlled obesity prevention trial is currently being conducted over a three year period (2010-present. The sample consists of 28 low-income, ethnically diverse child care centers with 1105 children (sample is 60% Hispanic, 15% Haitian, 12% Black, 2% non-Hispanic White and 71% of caregivers were born outside of the US. The purpose is to test the efficacy of a parent and teacher role-modeling intervention on children’s nutrition and physical activity behaviors. . The Healthy Caregivers-Healthy Children (HC2 intervention arm schools received a combination of (1 implementing a daily curricula for teachers/parents (the nutritional gatekeepers; (2 implementing a daily curricula for children; (3 technical assistance with meal and snack menu modifications such as including more fresh and less canned produce; and (4 creation of a center policy for dietary requirements for meals and snacks, physical activity and screen time. Control arm schools received an attention control safety curriculum. Major outcome measures include pre-post changes in child body mass index percentile and z score, fruit and vegetable and other nutritious food intake, amount of physical activity, and parental nutrition and physical activity knowledge, attitudes, and beliefs, defined by intentions and behaviors. All measures were administered at the beginning and end of the school year for year one and year two of the study for a total of 4 longitudinal time points for assessment. Discussion Although few attempts have been made to prevent obesity during the first years of life, this period may represent the best opportunity for obesity prevention. Findings from this investigation will inform both the fields of childhood obesity prevention and early childhood research about the effects of an obesity prevention program housed in the childcare setting.

Few obesity prevention programs for low-income preschoolers and their parents have been rigorously tested, and effects are modest. We are testing a novel obesity prevention program for low-income preschoolers built on the premise that children who are better able to self-regulate in the face of psychosocial stressors may be less likely to eat impulsively in response to stress. Enhancing behavioral self-regulation skills in low-income children may be a unique and important intervention approach to prevent childhood obesity. Methods/design The Growing Healthy study is a randomized controlled trial evaluating two obesity prevention interventions in 600 low-income preschoolers attending Head Start, a federally-funded preschool program for low-income children. Interventions are delivered by community-based, nutrition-education staff partnering with Head Start. The first intervention (n?=?200, Preschool Obesity Prevention Series (POPS, addresses evidence-based obesity prevention behaviors for preschool-aged children and their parents.

We hypothesize that POPS will yield positive effects compared to Usual Head Start, and that the combined intervention (POPS?+?IYS addressing behaviors well-known to be associated with obesity risk, as well as self-regulatory capacity, will be most effective in preventing excessive increases in child adiposity indices (body mass index, skinfold thickness. We will evaluate additional child outcomes using parent and teacher reports and direct assessments of food-related self-regulation. We will also gather process data on intervention implementation, including fidelity, attendance, engagement, and satisfaction. Discussion The Growing Healthy study will shed light on associations between self-regulation skills and obesity risk in low-income preschoolers. If the project is effective in preventing obesity, results can also provide critical insights into how best to deliver obesity prevention programming to parents and children in a community-based setting like Head Start in order to promote better health among at-risk children.

    Full Text Available A systematic review of the literature was conducted to identify the barriers that prevent practitioners from identifying and counseling parents and caregivers of overweight or obese children. Once identified, barriers were organized into thematic categories (parental, provider, and professional barriers and recommendations were generated to facilitate discussion about childhood obesity between professionals and parents. Childhood obesity is a significant public health problem. Healthcare providers must be able to effectively communicate with caregivers and put childhood obesity at the front of healthcare discussions. This article provides a synthesis of the relevant literature and makes recommendations for healthcare providers to overcome the barriers allowing healthier outcomes for children.

    Dehydroepiandrosterone (DHEA) exerts a wide variety of therapeutic effects against medical disorders, such as diabetes and obesity. However, the molecular basis of DHEA action remains to be clarified. Previously, we reported that DHEA-enhanced dual specificity protein phosphatase, designated DDSP, is one of the target molecules of DHEA. To examine the role of DDSP in DHEA signaling, we generated mice that carry a DDSP transgene in which expression is driven by the CAG promoter (DDSP-Tg). DDSP-Tg mice weighed significantly less than wild-type (WT) control mice when a high fat diet was supplied (p obese mice, DDSP-Tg mice with a db/db background were generated (DDSP-Tg db/db). We observed cancellation of obesity by the db/db mutation and development of a cachexic phenotype in DDSP-Tg db/db mice. In conclusion, our study shows that expression of DDSP leads to prevention of diet-induced and genetic (db/db) obesity. Anti-obese effects of DHEA might be mediated through DDSP, which might be a therapeutic target for intervention of obesity. PMID:26523513

    Salacia reticulata Wight (S. reticulata) is a herbal medicine used for treatment of early diabetes in Ayurvedic medicine. In previous reports, the extract of S. reticulata showed preventive effects on obesity and various metabolic disorders and a suppressive effect on differentiation in premature adipocytes. The aim of this research was to elucidate the therapeutic efficacy of the extract of S. reticulata on obesity and various metabolic disorders in 12-week-old TSOD mice with obesity and metabolic disorders and in mature 3T3-L1 adipocytes. In TSOD mice, S. reticulata therapy produced a reduction in body weight and mesenteric fat accumulation, an improvement in abnormal glucose metabolism, and an increase in adiponectin level in plasma. In addition, the mRNA expressions of hormone-sensitive lipase (HSL) and adiponectin were increased in mesenteric fat. In in vitro experiments, S. reticulata therapy produced suppression of intracellular triacylglycerol accumulation and enhancement of glycerol release into the medium in mature 3T3-L1 cells. The mRNA expressions of lipogenesis factor (peroxisome proliferator-activated receptor ?, lipoprotein lipase, CD36, and fatty acid binding protein 4) were down-regulated, while the expressions of lipolysis factor (adipose tissue triacylglycerol lipase and HSL) and adiponectin were up-regulated. Moreover, the extract of S. reticulata enhanced the expression of total AMP-activated protein kinase ? (AMPK?) and phosphorylated AMPK? in mature adipocytes. These findings demonstrate that the extract of S. reticulata has therapeutic effects on obesity and metabolic disorders by enhancing lipogenesis genes and suppressing lipolysis genes through the activation of AMPK? in adipocytes.

Thereafter, abstracts were reviewed and studies were selected based on predefined criteria. The characteristics of the selected studies and the results were extracted in a special form and consequently were reviewed and synthesized.Results: Price increase may lead to a reduction in consumption of the targeted products, but the subsequent effect on caloric intake may be much smaller. Only a limited number of the identified studies reported weight outcomes, most of which are either insignificant or very small in magnitude to make any improvement in public health.Conclusion: The effectiveness of a taxation policy to curb obesity is doubtful and available evidence in most studies is not very straightforward due to the multiple complexities in consumer behavior and the underling substitution effects. There is need to investigate in-depth the potential underlying mechanisms and the relationship between price-increase policies, obesity, and public health outcomes.

    Full Text Available The objective of the present study is to review the different publications associated with probiotics and obesity, as well as to get some new insights regarding the role of the microbiome in diseases such as obesity. An extensive search for scientific publications (studies in animal models, cells, clinical trials and reviews was performed in the following specialist computer databases (PubMed central (PMC-NCBI, Elsevier Journal, Scielo Spain, Scirus, Science Direct to establish the current status of the potential effect of probiotics in the control of obesity in humans, as well as the relationship between intestinal microbiota and obesity. The intestinal microbiota and oral probiotics have a positive effect on human health, as they can regulate the immune functions and protect from infections and chronic inflammatory processes. Although divergent results have recently been reported, it has been shown but not confirmed that intestinal microbiota might play a role as a new factor associated with the regulation of body weight and obesity-related diseases. The international MetaHIT project has shown that human microbiome populations can be grouped into three different enterotypes. Two of these enterotypes (Bacteroides and Ruminococcus seem to encode functions related to obesity. Although the relationship between intestinal microbiota and obesity are not yet well established, the attempt to manipulate intestinal microbiota through diet is suggested as a new plausible approach to prevent, or modify the risk of, obesity and its related diseases.

  4. Preventing childhood obesity: what are we doing right?

    2014-09-01

    After decades of increases, the prevalence of childhood obesity has declined in the past decade in New York City, as measured in children participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and public school students, with the greatest reductions occurring in the youngest children. Possible explanations were changes in demographics; WIC, day care, and school food policies; citywide obesity prevention policies, media messages; and family and community food consumption. Although the decreases cannot be attributed to any one cause, the most plausible explanation is changes in food consumption at home, prompted by media messages and reinforced by school and child care center policy changes. Continued media messages and policy changes are needed to sustain these improvements and extend them to other age groups. PMID:25033123

  5. Activation of transient receptor potential vanilloid type-1 channel prevents adipogenesis and obesity

    DEFF Research Database (Denmark)

    Zhang, Li Li; Yan Liu, Dao

    2007-01-01

    We tested the hypothesis that activation of transient receptor potential vanilloid type-1 (TRPV1) by capsaicin prevents adipogenesis. TRPV1 channels in 3T3-L1-preadipocytes and visceral adipose tissue from mice and humans were detected by immunoblotting and quantitative real-time RT-PCR. The effect of TRPV1 on cytosolic calcium was determined fluorometrically in 3T3-L1-preadipocytes and in human visceral fat tissue. Adipogenesis in stimulated 3T3-L1-preadipocytes was determined by oil red O-staining of intracellular lipid droplets, triglyceride levels, expression of peroxisome proliferator-activated receptor-gamma, and expression of fatty acid synthase. Long-term feeding experiments were undertaken in wild-type mice and TRPV1 knockout mice. We detected TRPV1 channels in 3T3-L1-preadipocytes and visceral adipose tissue from mice and humans. In vitro, the TRPV1 agonist capsaicin dose-dependently induced calcium influx and prevented the adipogenesis in stimulated 3T3-L1-preadipocytes. RNA interference knockdown of TRPV1 in 3T3-L1-preadipocytes attenuated capsaicin-induced calcium influx, and adipogenesis in stimulated 3T3-L1-preadipocytes was no longer prevented. During regular adipogenesis TRPV1 channels were downregulated which was accompanied by a significant and time-dependent reduction of calcium influx. Compared with lean counterparts in visceral adipose tissue from obese db/db and ob/ob mice, and from obese human male subjects we observed a reduced TRVP1 expression. The reduced TRPV1 expression in visceral adipose tissue from obese humans was accompanied by reduced capsaicin-induced calcium influx. The oral administration of capsaicin for 120 days prevented obesity in male wild type mice but not in TRPV1 knockout mice assigned to high fat diet. We conclude that the activation of TRPV1 channels by capsaicin prevented adipogenesis and obesity.

    As obesity rates increase, so too do the risks of type 2 diabetes, cardiovascular disease, and numerous other detrimental conditions. The prevalence of obesity in U.S. adults more than doubled between 1980 and 2010, from 15.0 to 36.1%. Although this trend may be leveling off, obesity and its individual, societal, and economic costs remain of grave concern. In June 2014, a Diabetes Care Editors' Expert Forum convened to review the state of obesity research and discuss the latest prevention initiatives and behavioral, medical, and surgical therapies. This article, an outgrowth of the forum, offers an expansive view of the obesity epidemic, beginning with a discussion of its root causes. Recent insights into the genetic and physiological factors that influence body weight are reviewed, as are the pathophysiology of obesity-related metabolic dysfunction and the concept of metabolically healthy obesity. The authors address the crucial question of how much weight loss is necessary to yield meaningful benefits. They describe the challenges of behavioral modification and predictors of its success. The effects of diabetes pharmacotherapies on body weight are reviewed, including potential weight-neutral combination therapies. The authors also summarize the evidence for safety and efficacy of pharmacotherapeutic and surgical obesity treatments. The article concludes with an impassioned call for researchers, clinicians, governmental agencies, health policymakers, and health-related industries to collectively embrace the urgent mandate to improve prevention and treatment and for society at large to acknowledge and manage obesity as a serious disease.

    2010-01-01

    Full Text Available This paper presents a community-school-higher education partnership approach to the prevention of childhood obesity. Public elementary school personnel, primarily teachers, participated in the design and delivery of a curriculum targeting primary caregivers of 8-9-year-old children. Theoretical framework and methodological approaches guided the development of a cognitive behavioral lifestyle intervention targeting childhood obesity prevention in the Commonwealth of the Northern Mariana Islands (CNMI, a U.S. commonwealth. This project demonstrated that in populations with health disparity, teachers can be a valuable and accessible resource for identifying key health issues of concern to communities and a vital partner in the development of parent and child interventions. Teachers also benefited by gaining knowledge and skills to facilitate student and parent learning and impact on personal and familial health. Successful community-school-higher education partnerships require consideration of local culture and community needs and resources. Moreover, within any community-school–higher education partnership it is essential that a time sensitive and culturally appropriate feedback loop be designed to ensure that programs are responsive to the needs and resources of all stakeholders, and that leaders and policymakers are highly engaged so they can make informed policy decisions.

    Cyclocarya paliurus (CP; qing qian liu), which is used as an herbal tea in China, has been confirmed to have therapeutic effects on hyperlipidemia and obesity, and therefore it is widely consumed to prevent metabolic diseases such as hyperlipidemia and diabetes. In this study, we investigated the preventive effects of CP on obesity and hyperlipidemia, as well as the underlying mechanisms involved in intestinal secretion of apolipoprotein (apo) B48. Sprague-Dawley rats were fed a high-fat diet (HFD) and with or without various concentrations of an ethanol extract of CP (CPE; 2, 4, or 8 g·(kg body mass)(-1)) administered by gavage for 8 weeks. From the results we see that CPE dose-dependently blocked increases in body mass, and decreased food utilization as well as visceral fat mass. Decreased serum levels of total cholesterol, triglycerides, and low density lipoprotein cholesterol, and elevated levels of high density lipoprotein cholesterol, as well as lowered levels of total cholesterol and triglycerides in the liver were also noticed in CPE-treated rats. Magnetic resonance images indicated that the abnormal fat storage induced by the HFD was obviously suppressed by CPE. In addition, ELISA analysis showed reduced fasting serum apoB48 in the CPE treatment groups. Based on the above results, CPE shows a promising preventive effect on obesity and hyperlipidemia, partially through suppressing intestinal apoB48 overproduction. PMID:26203820

    2009-08-01

    This pilot study examined the feasibility of an interactive obesity prevention program delivered to a class of fourth-grade students utilizing daily e-mail messages sent to the students' home computers. The study involved a single intact class of 22 students, 17 (77%) of whom submitted parental permission documentation and received e-mail messages each school day over the course of one month. Concerns regarding Internet safety and children's use of e-mail were addressed fairly easily. Cost/benefit issues for the school did not seem prohibitive. Providing e-mail access to students without a home computer was accomplished by loaning them personal digital assistant (PDA) devices. In larger interventions, loaning PDAs is probably not feasible economically, although cell phones may be an acceptable alternative. It was concluded that this type of interactive obesity prevention program is feasible from most perspectives. Data from a larger scale effectiveness study is still needed. PMID:19827452

    Obesity, mainly childhood obesity, is a worldwide concern. Childhood obesity continues to adulthood, and it is associated with multiple noncommunicable diseases. One important aspect in the fight against obesity is prevention, the earlier, the better. Social marketing is a novel concept being increasingly used as an approach to address social problems and more and more included in the community-based interventions aiming to change unhealthy behaviors. Although there is limited evidence of its...

    2012-03-01

    Full Text Available Abstract Background In 2005, we reported on the success of Comprehensive School Health (CSH in improving diets, activity levels, and body weights. The successful program was recognized as a "best practice" and has inspired the development of the Alberta Project Promoting active Living and healthy Eating (APPLE Schools. The project includes 10 schools, most of which are located in socioeconomically disadvantaged areas. The present study examines the effectiveness of a CSH program adopted from a "best practice" example in another setting by evaluating temporal changes in diets, activity levels and body weight. Methods In 2008 and 2010, we surveyed grade 5 students from approximately 150 randomly selected schools from the Canadian province of Alberta and students from 10 APPLE Schools. Students completed the Harvard Youth/Adolescent Food Frequency Questionnaire, questions on physical activity, and had their height and weight measured. Multilevel regression methods were used to analyze changes in diets, activity levels, and body weight between 2008 and 2010. Results In 2010 relative to 2008, students attending APPLE Schools were eating more fruits and vegetables, consuming fewer calories, were more physically active and were less likely obese. These changes contrasted changes observed among students elsewhere in the province. Conclusions These findings provide evidence on the effectiveness of CSH in improving health behaviors. They show that an example of "best practice" may lead to success in another setting. Herewith the study provides the evidence that investments for broader program implementation based on "best practice" are justified.

  14. Hypothyroidism and obesity: Cause or Effect

    International Nuclear Information System (INIS)

    Objective was to establish relationship between obesity and hypothyroidism and to analyze the frequency of primary hypothyroidism in obese patients and frequency of obesity in primary hypothyroidism patients. We conducted this retrospective, observational study in Department of Endocrinology and Obesity Clinic, Medwin Hospital, Hyderabad, India in March 2008. In the last 18 months (between September 2006 to February 2008), data on 625 consecutive primary hypothyroidism patients (Group I) and 450 patients from obesity clinic (Group II) were analyzed. Frequency difference between the 2 groups was assessed by Chi-square test. In Group I, 278/625 (44%) had body mass index (BMI) >25 kg/m2. Obesity was higher (46% versus 34%) in overt hypothyroidism than in subclinical hypothyroidism (p=0.21). More patients were overweight in overt hypothyroidism group than in subclinical hypothyroidism group (p=0.02). In obesity patients, overt hypothyroidism was present in 33% and subclinical hypothyroidism in 11% patients. Overall thyroid dysfunction was found more in obese individuals with varying degree of significance. Detailed studies are required to assess the cause and effect relation between obesity and hypothyroidism. (author)

Obesity during the adolescent years is associated with many adverse health consequences, including type 2 diabetes, hypertension, hyperlipidemia, and psychosocial problems. Because of substantial advances in technologies and wide acceptance by adolescents, it is now possible to use technology for healthy weight management and prevention of obesity. This systematic review used Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and aimed to evaluate the existing literature reported on the effectiveness of technology-based intervention (web-based, e-learning, and active video games in preventing obesity in adolescents. The primary aim of this review was to explore if components of specific interventions were associated with a reduction in body mass index. Research articles obtained from CINAHL, Embase, PubMed, PsycInfo, and the Cochrane database from1990 to 2014 were reviewed. A total of 131 published articles were identified, and 14 met the inclusion criteria of a randomized or nonrandomized clinical study with body mass index as primary outcome and/or secondary outcomes of diet/physical activity and/or psychosocial function, tested lifestyle interventions to prevent obesity, used technology, and studied adolescents (aged 12–18 years. The results indicated that six of 14 studies found body mass index and/or body fat decreased at short-term (less than 12 months follow-up. Six of eleven studies that examined physical activity or physical activity-related outcomes found an improved physical activity outcome (time playing active video games and increase in physical activity time, while five of seven studies which assessed dietary outcomes indicated improvement in dietary behaviors. Five of seven studies suggested an improvement in psychosocial function (reduced depression, improved self-esteem and efficacy, improvement on Behavior Assessment Scale in adolescents involved in the technology-based intervention. All effective interventions utilized dietary and physical activity strategies as part of intervention components. Because of the variation in duration of intervention (range 10 weeks to 2 years, it is not clear what length of intervention is most effective. Future research should assess the long-term impact of technology-based interventions and evaluate mediators and moderators for weight change in adolescents.

    Salud America! is a national network created to engage Latino researchers, health professionals and community leaders in actions to reduce Latino childhood obesity. An online survey of 148 Salud America! network members investigated relationships between (1) their levels of engagement with the network, (2) self- and collective-efficacy, and (3) behavioral intentions to engage in advocacy for policies that can help reduce Latino childhood obesity. Analyses of these data found that higher levels of Salud America! engagement was associated with collective-advocacy efficacy-greater confidence in organized group advocacy as a way of advancing policies to reduce Latino childhood obesity. A multiple regression analysis found that this sense of collective-efficacy moderately predicted intentions to engage in advocacy behaviors. Salud America! engagement levels were less strongly associated with members' confidence in their personal ability to be an effective advocate, yet this sense of self-efficacy was a very strong predictor of a behavioral intention to advocate. Based on these findings, new online applications aimed at increasing self- and collective-efficacy through peer modeling are being developed for Salud America! in order to help individuals interested in Latino childhood obesity prevention to connect with each other and with opportunities for concerted local actions in their communities.

    2015-01-01

    Children in rural areas face higher rates of obesity than children in urban areas, and their clinicians face challenges with preventing and managing obesity and translation of evidence into practice. We evaluated how the quality improvement (QI) intervention, Healthy Eating Active Living TeleHealth Community of Practice (HEALTH COP), at 7 rural California clinics addressed these challenges. Focus group interviews with QI team members assessed their experiences and factors related to adoption of key changes. Key challenges were clinician and staff buy-in, changing ingrained clinical practices, and motivating patient and families. Facilitators were top-down organizational requirements for QI, linkages to local QI resources, involvement of clinical champions, alignment with existing practices, incorporating a learning system connecting similar clinics, and clear and consistent communication channels. Evaluations of QI interventions should include not only measurement of effectiveness but also identification of factors associated with change and interactions with organizational processes and contexts.

    Full Text Available Abstract Background The first years of life are crucial to start preventive interventions that can have an impact on lifestyle and later overweight and obesity. Under the Italian National Health System (INHS, children are cared for by family pediatricians who perform health balances at regular intervals. The Italian Society of Preventive and Social Pediatrics (SIPPS has designed a randomized controlled trial (RCT to evaluate the effectiveness of family pediatricians for the prevention of childhood obesity in preschool children. We report the rationale and protocol of such trial, named the "Mi voglio bene" ("I love myself" study. Methods "Mi voglio bene" is a parallel-arm RCT. Family pediatricians willing to participate to the trial will be randomly assigned to a control group and to an experimental group. The control group will provide the usual standard of care while the experimental group will implement 10 preventive actions (promotion of breastfeeding, avoidance of solid foods, control of protein intake, avoidance of sugar-sweetened beverages, avoidance of bottle, active means of transportation, identification of early adiposity rebound, limitation of television viewing, promotion of movement, and teaching portion size at 10 time points during a 6-yr follow-up. The main outcome measures is the prevalence of overweight and obesity at 6 years of age. The experimental intervention is expected to reduce the prevalence of overweight and obesity from 25% to 20% and the study requires a total of 3610 children. Each pediatrician will enroll 30 consecutive newborns into the study so that a total of 120 pediatricians will participate to the study. Discussion "Mi voglio bene" is expected to provide important information for the INHS and possibly other institutional child care settings about the effectiveness of a pediatrician-based approach to the prevention of childhood obesity. We published this study protocol with the aim of opening a discussion with all people interested in fighting childhood obesity and to receive useful criticisms.

    2011-09-01

    Obesity is a serious global epidemic and the prevention strategies implemented have been insufficient. Numerous environmental factors have been associated with risk of obesity and their full consideration in prevention policies is important. The connection between food advertising on television and childhood obesity has been demonstrated. The large number of advertisements for unhealthy foods targeted at children through television and its possible impact on health has led some countries to legislate on this matter. However, a conceptual framework of reference enabling legislation must be internationally defined in order to achieve a real impact in preventing childhood obesity. This paper reviews scientific evidence on the relationship between food advertising and childhood obesity as a basis for developing public policies to regulate food marketing on television.

    Previous reviews of childhood obesity prevention have focused largely on schools and findings have been inconsistent. Funded by the US Agency for Healthcare Research and Quality (AHRQ) and the National Institutes of Health, we systematically evaluated the effectiveness of childhood obesity prevention programmes conducted in high-income countries and implemented in various settings. We searched MEDLINE®, Embase, PsycINFO, CINAHL®, ClinicalTrials.gov and the Cochrane Library from inception through 22 April 2013 for relevant studies, including randomized controlled trials, quasi-experimental studies and natural experiments, targeting diet, physical activity or both, and conducted in children aged 2-18 in high-income countries. Two reviewers independently abstracted the data. The strength of evidence (SOE) supporting interventions was graded for each study setting (e.g. home, school). Meta-analyses were performed on studies judged sufficiently similar and appropriate to pool using random effect models. This paper reported our findings on various adiposity-related outcomes. We identified 147 articles (139 intervention studies) of which 115 studies were primarily school based, although?other settings could have been involved. Most were conducted in the United States and within the past decade. SOE was high for physical activity-only interventions delivered in schools with home involvement or combined diet-physical activity interventions delivered in schools with both home and community components. SOE was moderate for school-based interventions targeting either diet or physical activity, combined interventions delivered in schools with home or community components or combined interventions delivered in the community with a school component. SOE was low for combined interventions in childcare or home settings. Evidence was insufficient for other interventions. In conclusion, at least moderately strong evidence supports the effectiveness of school-based interventions for preventing childhood obesity. More research is needed to evaluate programmes in other settings or of other design types, especially environmental, policy and consumer health informatics-oriented interventions. PMID:25893796

    2009-01-01

    Community-based interventions are an important component of obesity prevention efforts. The literature provides little guidance on priority-setting for obesity prevention in communities, especially for socially and culturally diverse populations. This paper reports on the process of developing prioritized, community-participatory action plans for obesity prevention projects in children and adolescents using the ANGELO (Analysis Grid for Elements Linked to Obesity) Framework. We combined stakeholder engagement processes, the ANGELO Framework (scans for environmental barriers, targeted behaviours, gaps in skills and knowledge) and workshops with key stakeholders to create action plans for six diverse obesity prevention projects in Australia (n = 3), New Zealand, Fiji and Tonga from 2002 to 2005. Some sites included sociocultural contextual analyses in the environmental scans. Target groups were under-5-year-olds (Australia), 4-12-year-olds (Australia) and 13-18-year-olds (all four countries). Over 120 potentialbehavioural, knowledge, skill and environmental elements were identified for prioritization leading into each 2-day workshop. Many elements were common across the diverse cultural communities; however, several unique sociocultural elements emerged in some cultural groups which informed their action plans. Youth were actively engaged in adolescent projects, allowing their needs to be incorporated into the action plans initiating the process of ownership. A common structure for the action plan promoted efficiencies in the process while allowing for community creativity and innovation. The ANGELO is a flexible and efficient way of achieving an agreed plan for obesity prevention with diverse communities. It is responsive to community needs, combines local and international knowledge and creates stakeholder ownership of the action plan.

    Full Text Available Abstract Background Developing effective prevention and intervention programs for the formative preschool years is seen as an essential step in combating the obesity epidemic across the lifespan. The overall goal of the current project is to measure the effectiveness of a healthy eating and childhood obesity prevention intervention, the MEND (Mind Exercise Nutrition Do It! program that is delivered to parents of children aged 2-4 years. Methods/Design This randomised controlled trial will be conducted with 200 parents and their 2-4 year old children who attend the MEND 2-4 program in metropolitan and regional Victoria. Parent-child dyads will attend ten 90-minute group workshops. These workshops focus on general nutrition, as well as physical activity and behaviours. They are typically held at community or maternal and child health centres and run by a MEND 2-4 trained program leader. Child eating habits, physical activity levels and parental behaviours and cognitions pertaining to nutrition and physical activity will be assessed at baseline, the end of the intervention, and at 6 and 12 months post the intervention. Informed consent will be obtained from all parents, who will then be randomly allocated to the intervention or wait-list control group. Discussion Our study is the first RCT of a healthy eating and childhood obesity prevention intervention targeted specifically to Australian parents and their preschool children aged 2-4 years. It responds to the call by experts in the area of childhood obesity and child health that prevention of overweight in the formative preschool years should focus on parents, given that parental beliefs, attitudes, perceptions and behaviours appear to impact significantly on the development of early overweight. This is 'solution-oriented' rather than 'problem-oriented' research, with its focus being on prevention rather than intervention. If this is a positive trial, the MEND2-4 program can be implemented as a national program. Trial Registration Australian New Zealand Clinical Trials Registry ACTRN12610000200088

  19. Beyond the Role of Dietary Protein and Amino Acids in the Prevention of Diet-Induced Obesity

    Directory of Open Access Journals (Sweden)

    Klaus J. Petzke

    2014-01-01

    Full Text Available High-protein diets have been shown to prevent the development of diet-induced obesity and can improve associated metabolic disorders in mice. Dietary leucine supplementation can partially mimic this effect. However, the molecular mechanisms triggering these preventive effects remain to be satisfactorily explained. Here we review studies showing a connection between high protein or total amino nitrogen intake and obligatory water intake. High amino nitrogen intake may possibly lower lipid storage, and prevent insulin resistance. Suggestions are made for further systematical studies to explore the relationship between water consumption, satiety, and energy expenditure. Moreover, these examinations should better distinguish between leucine-specific and unspecific effects. Research in this field can provide important information to justify dietary recommendations and strategies in promoting long-term weight loss and may help to reduce health problems associated with the comorbidities of obesity.

    Full Text Available Abstract Background The diets, physical activity and sedentary behavior levels of both children and adults in Australia are suboptimal. The family environment, as the first ecological niche of children, exerts an important influence on the onset of children’s habits. Parent modeling is one part of this environment and a logical focus for child obesity prevention initiatives. The focus on parent’s own behaviors provides a potential opportunity to decrease obesity risk behaviors in parents as well. Objective To assess the effect of a parent-focused early childhood obesity prevention intervention on first-time mothers’ diets, physical activity and TV viewing time. Methods The Melbourne InFANT Program is a cluster-randomized controlled trial which involved 542 mothers over their newborn’s first 18?months of life. The intervention focused on parenting skills and strategies, including parental modeling, and aimed to promote development of healthy child and parent behaviors from birth, including healthy diet, increased physical activity and reduced TV viewing time. Data regarding mothers’ diet (food frequency questionnaire, physical activity and TV viewing times (self-reported questionnaire were collected using validated tools at both baseline and post-intervention. Four dietary patterns were derived at baseline using principal components analyses including frequencies of 55 food groups. Analysis of covariance was used to measure the impact of the intervention. Results The scores of both the "High-energy snack and processed foods" and the "High-fat foods" dietary patterns decreased more in the intervention group: -0.22 (?0.42;-0.02 and ?0.25 (?0.50;-0.01, respectively. No other significant intervention vs. control effects were observed regarding total physical activity, TV viewing time, and the two other dietary patterns, i.e. “Fruits and vegetables” and “Cereals and sweet foods”. Conclusions These findings suggest that supporting first-time mothers to promote healthy lifestyle behaviors in their infants impacts maternal dietary intakes positively. Further research needs to assess ways in which we might further enhance those lifestyle behaviors not impacted by the InFANT intervention.

  1. Laminaria japonica as a food for the prevention of obesity and diabetes.

    2011-01-01

    Various seaweeds have traditionally been used as flavoring materials, food additives, and foodstuffs in many countries, especially those in Asia. The seaweed Laminaria japonica (LJ) is popular as "kombu" in Japanese cuisine. Laminaria sp. is one of the most important marine medicinal foodstuffs, as its biological functions have been widely investigated in both in vitro and in vivo experiments. This chapter introduces recent reports on the ability of Laminaria to prevent obesity and diabetes, and some approaches for effectively using the bioactivities found in Laminaria. The inhibitory effects of Laminaria sp. on triglyceride absorption were investigated in triglyceride-loaded mice and in mice with high-fat-diet-induced obesity. Shaved Laminaria, known as "tororokombu," showed more effective activities in these experiments. The active component was considered to be alginic acid in the water-soluble fraction. On the other hand, the antihyperglycemic effects of a hot water extract of immature Laminaria were investigated in carbohydrate-loaded mice and in in vitro experiments using Caco-2 cells. The potential usefulness of Laminaria sp. as marine medicinal foods may be increased through the use of different processing methods and/or growth stages. These reports suggest that LJ may be useful for preventing lifestyle-related diseases. PMID:22054948

    Messiah, S E; Lipshultz, S E; Natale, R A; Miller, T L

    2013-12-01

    In the past 20 years, the prevalence of obesity in the United States increased almost 50% among adults and by 300% in children. Today, 9.7% of all U.S. infants up to 2 years old have abnormally high weight-for-recumbent length; 25% of children under age 5 are either overweight or obese; and 17% of adolescents are obese. Ethnic disparities in the rates of obesity are also large and apparent in childhood. Further, 44% of obese adolescents have metabolic syndrome. Obese children tend to become obese adults; thus, in a decade, young adults will likely have much higher risks of chronic disease, which has tremendous implications for the healthcare system. However, early childhood may be the best time to prevent obesity. Teachers' healthy eating choices are positively associated with changes in body mass index percentiles for children, for example. In addition, 8 million children attend afterschool programs, which can successfully promote health and wellness and successfully treat obesity. This childhood epidemic of obesity and its health-related consequences in adolescents should be a clinical and public health priority. However, this major public health problem cannot be managed solely in clinical settings. Rather, public health strategies must be integrated into home and family, school and community-based settings.

  13. After-School Based Obesity Prevention Interventions: A Comprehensive Review of the Literature

    Directory of Open Access Journals (Sweden)

    Manoj Sharma

    2012-04-01

    Full Text Available The purpose of this article was to review primary prevention interventions targeting childhood obesity implemented in the after school environment from 2006 and 2011. A total of 20 interventions were found from 25 studies. Children in the interventions ranged from kindergarten to middle schoolers, however a majority was in the 4th and 5th grades. Most of the interventions targeted both physical activity and dietary behaviors. Among those that focused on only one dimension, physical activity was targeted more than diet. The duration of the interventions greatly varied, but many were short-term or brief. Many interventions were also based on some behavioral theory, with social cognitive theory as the most widely used. Most of the interventions focused on short-term changes, and rarely did any perform a follow-up evaluation. A major limitation among after school interventions was an inadequate use of process evaluations. Overall, interventions resulted in modest changes in behaviors and behavioral antecedents, and results were mixed and generally unfavorable with regards to indicators of obesity. Recommendations for enhancing the effectiveness of after school based childhood obesity interventions are presented.

    Background: Due to increasing problems with childhood and adolescent obesity in Austria PRESTO (PrEvention STudy of Obesity created a school based intervention program for promoting a healthy lifestyle in Austrian youth.

    Methods: PRESTO was carried out by a multi-disciplinary team including a physician, a psychologist, a nutritionist and an exercise physiologist. The study was carried out in 12 first grade school classes in Austria (2002-2004, mainly in Vienna (N=260. The control group consisted of 231 subjects. Medical examinations were performed and the participantsf knowledge on good nutrition and dietary habits were collected. Twelve nutrition sessions, one hour per week in each class, were conducted. Teachers were advised to discuss health issues in their classes and specific exercise physiologists were informed about how to integrate appropriate exercises into their lessons.

    Results: In comparison with control group, classes who performed PRESTO showed a significant knowledge of nutrition, consuming less unhealthy foods. These effects could be observed in the short term (14 weeks and at follow up (10 months. 24% subjects could be classified as being overweight (BMI .90.Perc..

    Conclusions: School-oriented intervention programs/studies, like PRESTO, are a potential way to demonstrate positive effect on nutrition, physical activity and healthy behaviours in youth, especially if carried out on a long-term basis. Ultimately PRESTO has proven to be a suitable programme to be disseminated onto schools throughout Austria.

  16. The IDEFICS Community-Oriented Intervention Programme : A New Model for Childhood Obesity Prevention in Europe?

    DEFF Research Database (Denmark)

    De Henauw, Stefaan; Verbestel, V.

    2011-01-01

    Background and objectives: The European Union—as well as other parts of the world—faces a major challenge of increasing incidence of overweight/obesity. In particular, the increase in childhood obesity gives rise to a strong imperative for immediate action. Yet, little is known about the effectiveness of community interventions, and further research in this field is needed. There is, however, a growing consensus that such research should start from the paradigm that the current living environments tend to counteract healthy lifestyles. Questioning these environments thoroughly can help to develop new pathways for sustainable health-promoting communities. Against this background, the IDEFICS (Identification and prevention of dietary- and lifestyle-induced health effects in children and infants) study developed and implemented innovative community-oriented intervention programmes for obesity prevention and healthy lifestyle primarily in children aged 2–10 years in eight European countries: Sweden, Estonia, Germany, Belgium, Hungary, Italy, Spain and Cyprus. Materials and methods: The IDEFICS community-oriented intervention study mobilised an integrated set of interventional efforts at different levels of society, with the aim of facilitating the adoption of a healthy obesity-preventing lifestyle. The overall programme has been composed of 10 modules: three at community level, six at school level and one for parents. The main focus was on diet, physical activity and stress-coping capacity. The sphere of action encompassed both children and their (grand) parents, schools, local public authorities and influential stakeholders in the community. All materials for the interventions were centrally developed and culturally adapted. Results: So far, the following has been achieved: focus group research, literature review and expert consultations were done in an early phase as a basis for the development of the intervention modules. The intervention mapping protocol was followed as guide for structuring the intervention research. The overall intervention programme's duration was 2 years, but a longer-term follow-up programme is under development. Conclusions: This large-scale European effort is expected to contribute significantly to the understanding of this major public health challenge.

    This paper is written as a briefing document with the aim of providing support to policy-makers and government officials tackling obesity and related non-communicable diseases. It is based on a symposium Obesity and non-communicable diseases: Learning from international experiences convened by the International Association for the Study of Obesity (now the World Obesity Federation) and its policy section, the International Obesity TaskForce (now World Obesity - Policy and Prevention). The symposium discussed a wide range of proposals to tackle the consumption of unhealthy food products, including interventions in the market through fiscal policies and marketing restrictions, measures to strengthen public health legislation and measures to limit agri-food company lobbying activities. It recognized the need for government leadership and action in order to reduce preventable deaths while improving economic performance and identified a need for governments to take a systems wide approach to tackling obesity and to work with civil society, especially to monitor the drivers of disease and to hold all stakeholders accountable for progress.

  5. Effects of obesity on vascular potassium channels

    DEFF Research Database (Denmark)

    Climent, Belen; Simonsen, Ulf

    2014-01-01

    This review is focused on the effects of obesity on function and expression of potassium (K) channels in the vasculature. Five families of K channels have been identified in the vascular wall, calcium-activated K (KCa) channels, inward-rectifier K (KIR) channels, ATP-sensitive K (KATP) channels, voltage-gated K (KV) channels and two-pore domain K (K2P) channels. In endothelial cells (EC) and vascular smooth muscle cells (VSMC) opening of K channels leads to hyperpolarisation followed by vasodilatation. In some vascular beds of animal models of obesity, vasodilatation mediated by KCa3.1 and KCa2.3 channels has been reported to remain unaltered or even increased, whereas vasodilatation involving KCa1.1 channel has consistently been reported to be impaired. Changes in expression and function of KIR and KATP channels have also been associated with impaired vasodilatation in animal models of obesity, and therefore activation of these channels may improve endothelial function and reduce the risk of major cardiovascular events. Expression of KV7.x channels is downregulated in small arteries from hypertensive animals and it would be interesting to assess whether these channels contribute to development of hypertension in obese patients. However, the role of KV7.x and K2P channels in regulation of blood pressure remains unexplored compared to other K channels. In conclusion, obesity and metabolic syndrome alter expression, function and sensitivity of vascular K channel subtypes causing smooth muscle dysfunction and probably endothelial dysfunction which makes these patients particularly prone to premature cardiovascular disease. Modulation of K channel activity by use of openers of e.g. KCa and KATP channels may also be attractive to counteract vascular dysfunction observed in obesity.

  8. Metabolic effects of obesity: A review

    Directory of Open Access Journals (Sweden)

    Parul Singla

    2010-07-01

    Full Text Available With the many recent advances in the biomedical world, vast changes are taking place in our growing knowledge of the physiological aspects of almost all the tissues and organs of the human body. One of the most prevalent topics of discussion is the question of obesity and its effect on the metabolic changes in the human body. The original classical role of adipose tissue as an energy storage organ has been greatly modified. We now know that it is an endocrine organ, producing adipokines like leptin, adiponectin, visfatin, resistin, apelin, etc, which modulate metabolic processes in the body. Since obesity is associated with an increase in the adipose tissue mass, these hormones may be expected to be produced in increased concentrations and may thus have a significant impact on the macronutrient metabolism. Further, these adipokines may interact with long term energy modulators like insulin. Even though the scientific community has started unravelling the mysteries of the close linkage between obesity, its hormones and their physiological effects, a lot still remains to be discovered. The present discussion makes an attempt to trace the basic modern day concepts of the role of obesity in various metabolic processes.

  11. Sedentarism, active lifestyle and sport: Impact on health and obesity prevention.

    González-Gross, Marcela; Meléndez, Agustín

    2013-09-01

    The benefits of regular physical activity have been known since ancient Greek. But in the last Century the scientific knowledge around this topic has progressed enormously, starting with the early studies of JN Morris and RS Paffenberger, who demonstrated that physical activity at work reduced incidence of cardiovascular disease and mortality. In the Harvard alumni study, the lowest risk was associated with a weekly output of 1000 to 2000 kcal performing vigorous activities. Further studies in all age groups have supported these findings and have added that even moderate levels of physical activity provide considerable benefits to health, including lower prevalence of overweight and obesity at all ages. Metabolic fat oxidation rate is highest at exercise intensities between 45 and 65% of VO2max. This means that people must be active regularly and force physiological mechanisms at certain intensities. All this body of evidence has contributed to current WHO physical activity recommendations of 150 min/week of moderate to vigorous physical activity (MVPA) in adults and elderly, and 60 min/day of MVPA in children and adolescents, with additional strength training, apart from adopting an active lifestyle. In the last 50 years, occupational physical activity has been reduced for about 120 kcal/day, and sedentarism has emerged as an additional risk factor to physical inactivity. Even if less than 60 min of TV time in adults have been related to lower average BMI, there is still a need for research to determine the appropriate dose of exercise in combination with sedentary behaviours and other activities in the context of our modern lifestyle in order to prevent obesity at all ages. As public health measures have failed to stop the obesity epidemic in the last 3 decades, there is clearly a need to change the paradigm. The inclusion of sport scientists, physical education teachers and other professionals in the multidisciplinary team which should be responsible for drawing the road map to prevent the increase of the obesity epidemic effectively is a "must" from our point of view.

  12. Dietary Protein in the Prevention of Diet-Induced Obesity and Co-Morbidities

    DEFF Research Database (Denmark)

    Tastesen, Hanne SØrup

    2014-01-01

    Background: Obesity and related co?morbidities are increasing problems worldwide and nutritional approaches to prevent and alleviate these diseases are thus of great interest. High?protein diets have been shown to prevent and alleviate obesity and co?morbidities in rodents and humans through increased energy expenditure and satiety. Similarly, protein from different sources and in different forms has been shown to modulate obesity and co?morbidities. However, the impact of protein from different sources consumed at normal dietary levels remains to be further elucidated. Obesity?prone C57BL/6J mice were fed obesity?promoting diets with protein from different sources, in different forms and at different levels to evaluate the affect on development of obesity, glucose intolerance and dyslipidemia. Results: In the present study the dietary level of protein, 16 versus 32 percent energy from protein, was found to be negligible in development of obesity and co?morbidities in mice. Seafood protein with high endogenous taurine and glycine contents was found to prevent diet?induced adiposity and dyslipidemia, both in ad libitum and pair?fed settings. The ability of seafood proteins to prevent these metabolic disturbances was found to associate with the high endogenous taurine and glycine concentrations and to concur with increased energy expenditure and a tendency towards increased voluntary locomotor activity. Consumption of a seafood protein?mixture prevented diet?induced development of obesity as compared to intake of chicken filet and preserved glucose tolerance compared to casein intake. Hydrolyzed casein was shown to prevent obesity compared to intact casein, which was associated with increased spontaneous locomotor activity in hydrolyzed casein?fed mice. No increase in energy expenditure, as assessed by indirect calorimetry, was observed after four weeks, but after eight weeks adaptations towards increased energy expenditure?capacity was present concurrent with altered energy substrate utilization in hydrolyzed caseinfed mice compared to mice fed the intact protein. Conclusions: We found that the source and form of protein has great impact on development and prevention of diet?induced adiposity, dyslipidemia, hyperinsulinemia and impairment of glucose tolerance through modulations of voluntary locomotor activity, energy expenditure and energy substrate metabolism in mice

    The second phase of Active Living Research (ALR-2, 2007-2012) focused on advancing the Robert Wood Johnson Foundation (RWJF)'s goal of reversing the childhood obesity epidemic. The mission was to stimulate and support research to identify environmental factors and policies that influence physical activity for children and families to inform effective childhood obesity prevention strategies, with an emphasis on the lower-income and racial/ethnic communities with highest childhood obesity prevalence. The present report describes ALR activities undertaken to accomplish three goals. The first goal-to build an evidence base-was furthered by funding 230 competitive grants to identify and evaluate promising environment and policy changes. More than 300 publications have been produced so far. The second goal-to build an interdisciplinary and diverse field of investigators-was supported through annual conferences and linked journal supplements, academic outreach to multiple disciplines, and grants targeting young investigators and those representing groups historically disadvantaged or underrepresented in RWJF-funded research. The third goal-to use research to inform policy and practice-was advanced through research briefs; webinars; research-translation grants supporting ALR grantees to design communications tailored to decision-maker audiences; active engagement of policymakers and other stakeholders in ALR program meetings and annual conferences; ALR presentations at policy-related meetings; and broad outreach through a widely used website, e-mailed newsletters, and social media. ALR-2 findings and products have contributed to a rapid increase in the evidence base and field of active living research, as documented by an independent program evaluation. PMID:24439355

    O'Shea, Donal

    2012-02-01

    BACKGROUND: Obese individuals who smoke have a 14 year reduction in life expectancy. Both obesity and smoking are independently associated with increased risk of malignancy. Natural killer cells (NK) are critical mediators of anti-tumour immunity and are compromised in obese patients and smokers. We examined whether NK cell function was differentially affected by cigarette smoke in obese and lean subjects. METHODOLOGY AND PRINCIPAL FINDINGS: Clinical data and blood were collected from 40 severely obese subjects (BMI>40 kg\\/m(2)) and 20 lean healthy subjects. NK cell levels and function were assessed using flow cytometry and cytotoxicity assays. The effect of cigarette smoke on NK cell ability to kill K562 tumour cells was assessed in the presence or absence of the adipokines leptin and adiponectin. NK cell levels were significantly decreased in obese subjects compared to lean controls (7.6 vs 16.6%, p = 0.0008). NK function was also significantly compromised in obese patients (30% +\\/- 13% vs 42% +\\/-12%, p = 0.04). Cigarette smoke inhibited NK cell ability to kill tumour cell lines (p<0.0001). NK cells from obese subjects were even more susceptible to the inhibitory effects of smoke compared to lean subjects (33% vs 28%, p = 0.01). Cigarette smoke prevented NK cell activation, as well as perforin and interferon-gamma secretion upon tumour challenge. Adiponectin but not leptin partially reversed the effects of smoke on NK cell function in both obese (p = 0.002) and lean controls (p = 0.01). CONCLUSIONS\\/SIGNIFICANCE: Obese subjects have impaired NK cell activity that is more susceptible to the detrimental effects of cigarette smoke compared to lean subjects. This may play a role in the increase of cancer and infection seen in this population. Adiponectin is capable of restoring NK cell activity and may have therapeutic potential for immunity in obese subjects and smokers.

    2009-11-01

    Full Text Available Abstract Background The aim of the ACE-Obesity study was to determine the economic credentials of interventions which aim to prevent unhealthy weight gain in children and adolescents. We have reported elsewhere on the modelled effectiveness of 13 obesity prevention interventions in children. In this paper, we report on the cost results and associated methods together with the innovative approach to priority setting that underpins the ACE-Obesity study. Methods The Assessing Cost Effectiveness (ACE approach combines technical rigour with 'due process' to facilitate evidence-based policy analysis. Technical rigour was achieved through use of standardised evaluation methods, a research team that assembles best available evidence and extensive uncertainty analysis. Cost estimates were based on pathway analysis, with resource usage estimated for the interventions and their 'current practice' comparator, as well as associated cost offsets. Due process was achieved through involvement of stakeholders, consensus decisions informed by briefing papers and 2nd stage filter analysis that captures broader factors that influence policy judgements in addition to cost-effectiveness results. The 2nd stage filters agreed by stakeholders were 'equity', 'strength of the evidence', 'feasibility of implementation', 'acceptability to stakeholders', 'sustainability' and 'potential for side-effects'. Results The intervention costs varied considerably, both in absolute terms (from cost saving [6 interventions] to in excess of AUD50m per annum and when expressed as a 'cost per child' estimate (from Conclusion The use of consistent methods enables valid comparison of potential intervention costs and cost-offsets for each of the interventions. ACE-Obesity informs policy-makers about cost-effectiveness, health impact, affordability and 2nd stage filters for important options for preventing unhealthy weight gain in children. In related articles cost-effectiveness results and second stage filter considerations for each intervention assessed will be presented and analysed.

    Full Text Available Obesity impacts the U.S. military by affecting the health and readiness of active duty service members and their families. Preventing Obesity in Military Communities (POMC is a comprehensive research program within Patient Centered Medical Homes (PCMHs in three Military Training Facilities. This paper describes three pilot randomized controlled trials that target critical high risk periods for unhealthy weight gain from birth to young adulthood: (1 pregnancy and early infancy (POMC-Mother-Baby, (2 adolescence (POMC-Adolescent, and (3 the first tour of duty after boot camp (POMC-Early Career. Each study employs a two-group randomized treatment or prevention program with follow up. POMC offers a unique opportunity to bring together research and clinical expertise in obesity prevention to develop state-of-the-art programs within PCMHs in Military Training Facilities. This research builds on existing infrastructure that is expected to have immediate clinical benefits to DoD and far-reaching potential for ongoing collaborative work. POMC may offer an economical approach for widespread obesity prevention, from conception to young adulthood, in the U.S. military as well as in civilian communities.

  16. Prevention of childhood obesity - what type of evidence should we consider relevant?

    DEFF Research Database (Denmark)

    Doak, C; Heitmann, B L

    2009-01-01

    Two reviews, one by Summerbell et al. and the other by Doak et al. came to very different conclusions about the effectiveness of childhood obesity interventions. The aim of this commentary is to assess the extent to which inclusion and exclusion criteria, and the definition of effective outcomes, explain discrepant results. Differences in results were compared by inclusion criteria and outcome definitions. The most important summary recommendations for inclusion/exclusion criteria were to exclude all non-peer review articles, to maintain a 6-month lower limit for duration of study, to include interventions from before 1990, to include pre-school age groups, to include pilot studies and to intervene in high-risk communities. Authors did not reach consensus regarding inclusion of aims not specific to preventing weight gain and the manner of assessment of anthropometric measures. Combining both reviews and applying agreed exclusion criteria leaves 30 interventions; 50% are positive. Excluding studies without an aim specific to preventing weight gain leaves 10/24 (42%) positive interventions. The differences in the results of these two reviews relate to the inclusion criteria and outcome assessments. These findings underscore the importance of the evidence considered in assessing interventions.

    The aim of this cross-sectional study was to use social cognitive theory to predict overweight and obesity behaviors in adolescent girls in Iran. Valid and reliable questionnaires about nutritional and physical activity regarding social cognitive theory constructs (self-efficacy, social support, outcome expectations, and outcome expectancies), dietary habits, and physical activity were filled by 172 overweight and obese girl adolescents. The mean age and body mass index were 13.4?±?0.6 years and 28.2?±?3.6?kg/m(2), respectively. Body mass index was significantly related to hours of television viewing (p?=?.003) and grams of junk food (p?=?.001). None of the social cognitive theory constructs were found to be significant predictors for servings of fruits and vegetables, grams of junk foods, minutes of physical activity, and hours of sedentary behaviors. In future, more culturally appropriate models need to be developed in Iran that can explain and predict prevention behaviors of obesity in Iranian adolescents. PMID:25856805

    Despite isolated areas of improvement, no country to date has reversed its obesity epidemic. Governments, together with a broad range of stakeholders, need to act urgently to decrease the prevalence of obesity. In this Series paper, we review several regulatory and non-regulatory actions taken around the world to address obesity and discuss some of the reasons for the scarce and fitful progress. Additionally, we preview the papers in this Lancet Series, which each identify high-priority actions on key obesity issues and challenge some of the entrenched dichotomies that dominate the thinking about obesity and its solutions. Although obesity is acknowledged as a complex issue, many debates about its causes and solutions are centred around overly simple dichotomies that present seemingly competing perspectives. Examples of such dichotomies explored in this Series include personal versus collective responsibilities for actions, supply versus demand-type explanations for consumption of unhealthy food, government regulation versus industry self-regulation, top-down versus bottom-up drivers for change, treatment versus prevention priorities, and a focus on undernutrition versus overnutrition. We also explore the dichotomy of individual versus environmental drivers of obesity and conclude that people bear some personal responsibility for their health, but environmental factors can readily support or undermine the ability of people to act in their own self-interest. We propose a reframing of obesity that emphasises the reciprocal nature of the interaction between the environment and the individual. Today's food environments exploit people's biological, psychological, social, and economic vulnerabilities, making it easier for them to eat unhealthy foods. This reinforces preferences and demands for foods of poor nutritional quality, furthering the unhealthy food environments. Regulatory actions from governments and increased efforts from industry and civil society will be necessary to break these vicious cycles. PMID:25703111

    2015-03-01

    Obesity prevention programs that are delivered in after-school programs are needed as a focus on curriculum can make it difficult to include this health programming during the school day. The current study examined the implementation of 2 pilot programs in different after-school programs for young children. There were 36 children in the intervention groups and 18 children in comparison groups. Children learned about healthy eating and increasing involvement in physical activity. Lessons were based on the Traffic Light Diet. Results indicated improvement in children's reports of their eating habits. Activity levels improved in 1 school, but not in the other. Parents and children were satisfied with the program and children demonstrated good knowledge of the interventions to promote healthy eating. Future studies should include larger sample sizes and evaluation of the effectiveness of different components of the intervention. Nurses can play a key role in disseminating information and designing and leading after-school programs to improve child knowledge about healthy eating and exercise. Nursing students may also benefit from assisting with conducting these types of programs to improve their experience in health prevention programming. PMID:25365576

    These guidelines for obesity prevention programs encourage a health-centered, rather than weight-centered, approach that focuses on the whole child, physically, mentally, and socially. The emphasis is on living actively, eating in normal and healthful ways, and creating a nurturing environment that helps children recognize their own worth and respects cultural foodways and family traditions. It is recognized that obesity, eating disorders, hazardous weight loss, nutrient deficiencies, size discrimination, and body hatred are all interrelated and need to be addressed in comprehensive ways that do no harm.

    2013-01-01

    The incidence of obesity, increased weight gain and the popularity of high-fat \\/ high-sugar diets are seriously impacting upon the global population. Billions of individuals are affected, and although diet and lifestyle are of paramount importance to the development of adult obesity, compelling evidence is emerging which suggests that maternal obesity and related disorders may be passed on to the next generation by non-genetic means. The processes acting within the uteri of obese mothers may permanently predispose offspring to a diverse plethora of diseases ranging from obesity and diabetes to psychiatric disorders. This review aims to summarise some of the molecular mechanisms and active processes currently known about maternal obesity and its effect on foetal and neonatal physiology and metabolism. Complex and multifactorial networks of molecules are intertwined and culminate in a pathologically synergistic manner to cause disruption and disorganisation of foetal physiology. This altered phenotype may potentiate the cycle of intergenerational transmission of obesity and related disorders.

    Science.gov (United States)

    Ayres-de-Campos, Diogo

    2015-04-01

    Caesarean section in obese patients is associated with an increased risk of surgical wound complications, including haematoma, seroma, abscess and dehiscence. This review focusses on the available strategies to decrease wound complications in this population, and on the clinical management of these situations. Appropriate dose of prophylactic antibiotics, closure of the subcutaneous tissue, and avoidance of subcutaneous drains reduce the incidence of wound complications associated with caesarean section in obese patients. For treatment of superficial wound infection associated with dehiscence, there are data from general surgery patients to suggest that the use of vacuum-assisted devices leads to faster healing and that surgical reclosure is preferable to healing by secondary intention, when there are no signs of ongoing infection. There is a need for stronger evidence regarding the prevention and management of wound complications for caesarean section in obese women. PMID:25457856

    Full Text Available Obesity is a growing issue for all children. Many experts say that preventing obesity is largely a matter of eating the right foods and getting enough physical activity. This advice doesn’t recognize the fact that First Nations, Inuit, and Métis children face unique barriers to growing up healthy and strong simply because of theiridentity. This paper discusses how the social determinants of health impact the ability of Aboriginal children to grow up free of obesity. The paper highlights results from a community-based research project conducted amongst Aboriginal parents and service providers in Ontario who wish to prevent obesity amongst their ownyoung children and clients. Research was carried out over two years to help develop a “toolkit” and training program to help service provides increase efforts to prevent obesity amongst First Nations, Inuit, and Métis children from the ages of 2 to 6 in Ontario.

    Full Text Available Background: Increase in the prevalence of childhood and adolescence obesity in recent years caused many investigations to be held on effective factors on childhood obesity. Environmental factors have a strong impact and are investigated in many studies worldwide. The objective of this study was to determine the effective factors in Neishabur primary school children.Materials and Method: Using two stage cluster sampling from 60 Neishbur primary schools, all students who had body mass index(BMI ?95 percentile, were identified as obese (n=114 and 102 students of the same age and gender were indicated as non-obese pupils. Data were collected by questionnaires. Results: Our analyzed data showed that the mean birth weight in obese cases was significantly more than the others. The ratio of first and second born children in obese group was higher than of the non-obese. The ratio of pupils starting complementary feeding earlier than 6 month of age was significantly higher in obese (80.7% than non-obese children (46.1%. Conclusion: High birth weight, birth order and early treatment with complementary foods were associated with obesity among Neishabur primary school children.

    2013-02-01

    Full Text Available Abstract Background Obesity is increasing in the child-bearing population as are the rates of gestational diabetes. Gestational diabetes is associated with higher rates of Cesarean Section for the mother and increased risks of macrosomia, higher body fat mass, respiratory distress and hypoglycemia for the infant. Prevention of gestational diabetes through life style intervention has proven to be difficult. A Finnish study showed that ingestion of specific probiotics altered the composition of the gut microbiome and thereby metabolism from early gestation and decreased rates of gestational diabetes in normal weight women. In SPRING (the Study of Probiotics IN the prevention of Gestational diabetes, the effectiveness of probiotics ingestion for the prevention of gestational diabetes will be assessed in overweight and obese women. Methods/design SPRING is a multi-center, prospective, double-blind randomized controlled trial run at two tertiary maternity hospitals in Brisbane, Australia. Five hundred and forty (540 women with a BMI > 25.0 kg/m2 will be recruited over 2 years and receive either probiotics or placebo capsules from 16 weeks gestation until delivery. The probiotics capsules contain > 1x109 cfu each of Lactobacillus rhamnosus GG and Bifidobacterium lactis BB-12 per capsule. The primary outcome is diagnosis of gestational diabetes at 28 weeks gestation. Secondary outcomes include rates of other pregnancy complications, gestational weight gain, mode of delivery, change in gut microbiome, preterm birth, macrosomia, and infant body composition. The trial has 80% power at a 5% 2-sided significance level to detect a >50% change in the rates of gestational diabetes in this high-risk group of pregnant women. Discussion SPRING will show if probiotics can be used as an easily implementable method of preventing gestational diabetes in the high-risk group of overweight and obese pregnant women.

    Full Text Available New societies, specially those that are transitioning towesternized lifestyles, are experiencing substantial increases inprevalence of obesity that is showing epidemic characteristicsin several communities. Besides it is well accepted that geneticfactors have an important role in weight control, the observedexplosion of obesity seen in the last century can not be explainedexclusively by alterations in genes that occurred in this shortperiod of time but it is much more suitable to be the result ofenvironmental changes related to the contemporaryindustrialization and technological advances. The primaryenvironmental determinants of obesity are those related to theincrease in caloric intake and low levels of activity thatgenetically susceptible subjects to the weight gain are exposedby the modern style of living. Stimulated by the cheaper andgreater availability of food, the increase in automation andmechanization facilitating the physical inactivity and thecontinuous psychological stress the modern man is actually moreexposed to behavior changes favoring the weight gain. Sinceobesity is widely recognized to be an important cardiovascularand diabetes risk factor, prevention of obesity must be recognizedby policy-makers as an important public health actions to protecthealth. To combat the epidemic of obesity we must cure the“toxic environmental” changing our behavior and promoting newfood technologies.

    Full Text Available Back ground: Obesity is emerging global epidemic in young adults who form the productive group of the society. This has been called as new world syndrome and is a massive reflection of social, economic and cultural problems currently faced by the developing and developed countries. As cardiac autonomic dysfunction often coexists with obesity, early detection of autonomic impairment by simple investigations of autonomic function, can be potentially important to prevent future complications. Objective: To identify cardiovascular autonomic dysfunction in asymptomatic obese young adults. Study design: This study was conducted in the department of Physiology at Kakatiya Medical College, Warangal, A.P, 30 apparently healthy obese subjects of both sex with BMI > 25 kg/sqm were taken as study group. Age and sex matched 30 normal weight subjects (BMI 18.5-22.9 kg/ sqm taken as control group. Methods: Ewing’s battery of 5 noninvasive cardiovascular reflex tests were done for assessing autonomic function. These autonomic function parameters were correlated with BMI, Unpaired Student‘t’ test and Pearson correlation coefficient test were used for statistical analysis. Results: Mean values of all cardiovascular reflex tests were significantly lower in the study group. Conclusion: The results indicate that cardiovascular autonomic dysfunction is present in otherwise healthy obese young adults.

    Context: Research consistently shows that the majority of American children do not consume diets that meet the recommendations of the Dietary Guidelines for Americans, nor do they achieve adequate levels of daily physical activity. As a result, more children are overweight today than at any other time in U.S. history. Schools offer many opportunities to develop strategies to prevent obesity by creating environments in which children eat healthfully and engage regularly in physical activity.

    To build on a growing interest in community-based obesity prevention programs, methods are needed for matching intervention strategies to local needs and assets. We used the Community Readiness Model (CRM), a structured interview guide and scoring system, to assess community readiness to act on childhood obesity prevention, furthering a replication study of a successful intervention. Using the CRM protocol, we conducted interviews with 4 stakeholders in each of 10 communities of similar size, socioeconomic status, and perceived readiness to implement a community-wide obesity prevention intervention. Communities were in California, Florida, Illinois, Massachusetts, New York, North Carolina, Pennsylvania, and Tennessee. The 4 stakeholders were the mayor or city manager, the school superintendent, the school food service director, and a community coalition representative. Interviews were recorded and professionally transcribed. Pairs of trained reviewers scored the transcriptions according to CRM protocol. The CRM assesses 9 stages of readiness for 6 dimensions: existing community efforts to prevent childhood obesity, community knowledge about the efforts, leadership, community climate, knowledge about the issue, and resources. We calculated an overall readiness score for each community from the dimension scores. Overall readiness scores ranged from 2.97 to 5.36 on the 9-point scale. The mean readiness score, 4.28 (SD, 0.68), corresponds with a "preplanning" level of readiness. Of the 6 dimensions, community climate varied the least (mean score, 3.11; SD, 0.64); leadership varied the most (mean score, 4.79; SD, 1.13). The CRM quantified a subjective concept, allowing for comparison among 10 communities. Dimension scores and qualitative data from interviews helped in the selection of 6 communities for a replication study. PMID:22005643

    2013-01-01

    With an estimated 12.1% of children aged 2-5 years already obese, prevention efforts must target our youngest children. One of the best places to reach young children for such efforts is the early care and education setting (ECE). More than 11 million U.S. children spend an average of 30 hours per week in ECE facilities. Increased attention at the national, state, and community level on the ECE setting for early obesity prevention efforts has sparked a range of innovative efforts. To assist these efforts, CDC developed a technical assistance and training framework - the Spectrum of Opportunities for Obesity Prevention in the ECE setting - which also served as the organizing framework for the Weight of the Nation ECE track. Participants highlighted their efforts at national, state, and local levels pursuing opportunities on the Spectrum, the standards and best practices that had been the emphasis of their efforts, and common steps for developing, implementing, and evaluating initiatives. Strong leadership and collaboration among a broad group of stakeholders; systematic assessment of needs, opportunities and resources; funding sources; and training and professional development were reported to be integral for successful implementation of standards and best practices, and sustainability.

    2015-12-01

    Transverse rectus abdominis musculocutaneous (TRAM) flap is the most common procedure performed for breast reconstruction after mastectomy for breast cancer. Obesity is a relative contraindication, and complex modifications have been proposed in the pedicled technique for obese patients. We studied ischemic complications in our patients to investigate the effect of body weight on the outcome of TRAM flap breast reconstruction. Pertinent data from medical records of patients receiving a TRAM flap surgery from 1986 to 2011 were extracted. Patients were divided into three groups based on the body mass index (BMI): normal (30 kg/m(2)). Flap necrosis is defined as any visible nonviable tissue in the reconstructed breast. It was observed that 117 patients had received TRAM flap reconstruction. Fifty-eight patients were excluded. Of the remaining 59 cases, 24 had normal BMI, 21 were overweight, and 14 were obese. No patient was found to develop flap necrosis. Outcome of TRAM flap breast reconstruction in obese patients is similar to nonobese patients. No major necrosis in need of reoperation was identified in the studied obese patients. It was concluded that categorizing obesity as a relative contraindication to TRAM flap breast reconstruction should be revisited based on larger cohort studies. PMID:26730022

  12. Ethical Standards to Guide the Development of Obesity Policies and Programs; Comment on “Ethical Agreement and Disagreement about Obesity Prevention Policy in the United States”

    Directory of Open Access Journals (Sweden)

    David Buchanan

    2013-11-01

    Full Text Available The recent report by Barnhill and King about obesity prevention policy raises important issues for discussion and analysis. In response, this article raises four points for further consideration. First, a distinction between equality and justice needs to be made and consistently maintained. Second, different theories of justice highlight one additional important source of disagreement about the ethical propriety of the proposed obesity prevention policies. Third, another point of contention arises with respect to different understandings of the principle of respect for autonomy due to its often-mistaken equation with simple, unfettered freedom. Finally, based on a more robust definition of autonomy, the key issues in obesity prevention policies can be suitably re-framed in terms of whether they advance just social conditions that enable people to realize human capabilities to the fullest extent possible.

    Full Text Available A pandemia da obesidade juvenil e do sedentarismo está relacionada com o maior risco de doenças cardiovasculares no futuro. Ambas com fisiopatologia inflamatória, essas condições têm atraído significativa atenção científica. O início dos eventos que agridem o endotélio vascular pode ocorrer na infân [...] cia, porém, sinais clínicos da aterosclerose geralmente só aparecem na fase adulta. O tecido adiposo é hoje reconhecido por seu papel ativo, induzindo a produção de citocinas pró e anti-inflamatórias, como o fator de necrose tumoral-alfa, as interleucinas 1, 6 e 10, a proteína C-reativa e outras. Há várias evidências de que os níveis sanguíneos dessas citocinas se encontram mais altos em indivíduos com excesso de peso, inclusive crianças e adolescentes. A prevenção precoce, desde a infância, apresenta-se como a melhor maneira de evitar os danos da obesidade na fase adulta, enquanto o potencial da prática regular de exercícios físicos tem se mostrado surpreendente. Sua ação anti-inflamatória se manifesta através de menores concentrações séricas de interleucina 6, de proteína C-reativa e leptina, além de aumentos na adiponectina. Observa-se escassez de estudos randomizados e controlados avaliando as relações entre obesidade, inflamação e exercícios para a população jovem. Com resultados às vezes controversos, a maioria das conclusões é procedentede estudos com adultos. O objetivo desta revisão é avaliar o papel anti-inflamatório, e assim cardioprotetor, da atividade física regular na obesidade infantojuvenil.

The beginning of the events related to atherosclerosis may occur in child [...] hood, generating endothelial and metabolic dysfunction; however, the symptoms usually only appear later on, in adulthood. The fat tissue is recognized as being metabolically active, stimulating the production of inflammatory cytokines, such as the tumoral necrosis factor, interleukines 1, 6 and 10, C-reactive protein, among others. There is plenty of evidence that the serum levels of these citokines are higher in overweight individuals, including children and adolescents. Early prevention as young as possible is the best way to avoid future consequences of obesity. In this context, the potential benefits of regular physical exercise have been surprising. Researchers have shown evidence of anti-inflammatory responses, including lower levels of interleukine 6, C-reactive protein, leptin, besides higher levels of adiponectins after engagement in regular physical activity. However, we still have few controlled randomized studies addressing the relations between obesity, inflammation and exercise for the pediatric population. There are controversial findings in this field, and many of them come from adult studies. Thus, the purpose of the present review is to evaluate the metabolic role of physical exercise in juvenile obesity, aiming at heart protection.

    Full Text Available A pandemia da obesidade juvenil e do sedentarismo está relacionada com o maior risco de doenças cardiovasculares no futuro. Ambas com fisiopatologia inflamatória, essas condições têm atraído significativa atenção científica. O início dos eventos que agridem o endotélio vascular pode ocorrer na infância, porém, sinais clínicos da aterosclerose geralmente só aparecem na fase adulta. O tecido adiposo é hoje reconhecido por seu papel ativo, induzindo a produção de citocinas pró e anti-inflamatórias, como o fator de necrose tumoral-alfa, as interleucinas 1, 6 e 10, a proteína C-reativa e outras. Há várias evidências de que os níveis sanguíneos dessas citocinas se encontram mais altos em indivíduos com excesso de peso, inclusive crianças e adolescentes. A prevenção precoce, desde a infância, apresenta-se como a melhor maneira de evitar os danos da obesidade na fase adulta, enquanto o potencial da prática regular de exercícios físicos tem se mostrado surpreendente. Sua ação anti-inflamatória se manifesta através de menores concentrações séricas de interleucina 6, de proteína C-reativa e leptina, além de aumentos na adiponectina. Observa-se escassez de estudos randomizados e controlados avaliando as relações entre obesidade, inflamação e exercícios para a população jovem. Com resultados às vezes controversos, a maioria das conclusões é procedentede estudos com adultos. O objetivo desta revisão é avaliar o papel anti-inflamatório, e assim cardioprotetor, da atividade física regular na obesidade infantojuvenil.Nowadays, juvenile obesity and physical inactivity are pandemic conditions which relate to a greater future risk of cardiovascular diseases.

    2008-03-01

    Full Text Available Abstract Background Multiple factors combine to support a compelling case for interventions that target the development of obesity-promoting behaviours (poor diet, low physical activity and high sedentary behaviour from their inception. These factors include the rapidly increasing prevalence of fatness throughout childhood, the instigation of obesity-promoting behaviours in infancy, and the tracking of these behaviours from childhood through to adolescence and adulthood. The Infant Feeding Activity and Nutrition Trial (INFANT aims to determine the effectiveness of an early childhood obesity prevention intervention delivered to first-time parents. The intervention, conducted with parents over the infant's first 18 months of life, will use existing social networks (first-time parent's groups and an anticipatory guidance framework focusing on parenting skills which support the development of positive diet and physical activity behaviours, and reduced sedentary behaviours in infancy. Methods/Design This cluster-randomised controlled trial, with first-time parent groups as the unit of randomisation, will be conducted with a sample of 600 first-time parents and their newborn children who attend the first-time parents' group at Maternal and Child Health Centres. Using a two-stage sampling process, local government areas in Victoria, Australia will be randomly selected at the first stage. At the second stage, a proportional sample of first-time parent groups within selected local government areas will be randomly selected and invited to participate. Informed consent will be obtained and groups will then be randomly allocated to the intervention or control group. Discussion The early years hold promise as a time in which obesity prevention may be most effective. To our knowledge this will be the first randomised trial internationally to demonstrate whether an early health promotion program delivered to first-time parents in their existing social groups promotes healthy eating, physical activity and reduced sedentary behaviours. If proven to be effective, INFANT may protect children from the development of obesity and its associated social and economic costs. Trial registration Current Controlled Trials ISRCTN81847050

    Abstract to the 4th European Conference of Health Promoting Schools 1 May 2013 Authors 1. Ane Høstgaard Bonde (ahbo@steno.dk). Steno Health Promotion Center 2. Peter Bentsen 3. Anette Lykke Hindhede Title Motivational Interviewing by School Nurses: Spirit, Techniques, and Dilemmas in the Prevention of Child Obesity Introduction (max 1500 characters) - 1283 School nurses play a central role in school-based, preventive health services in Denmark (National Board of Health, 2011), and they may play an important role in obesity prevention as well (Kubik et al., 2008). The City of Copenhagen has monitored the growth of school children for many years and has observed an increasing prevalence of overweight and obesity (Pearson et al., 2010). In response to this, The Child and Youth Department of Copenhagen chose a prevention strategy targeting children with a high risk of obesity with an intervention conducted by school nurses using motivational interviewing. Motivational interviewing is a counselling method to bring about behavioural change (Miller and Rollnick 1995). Effect has been documented for a range of problem behaviours related to lifestyle diseases in adults (Rubak et al. 2005; Söderlund et al. 2011). The use of motivational interviewing by school nurses for the prevention of child obesity in a family intervention is still new, and evidence on the potentials and problems is scarce (Resnicow, Davis and Rollnick, 2006; Morrison-Sandberg et al., 2011). Thus, the objective of this study is to investigate the experiences, practices and perceptions of school nurses when applying motivational interviewing to overweight children and their parents. Theoretical/analytical framework (max 1500) pt. 690. The study is based on the theory of motivational interviewing presented by its originators, Miller and Rollnick, in three conceptual papers (Miller & Rollnick, 1995; Emmons & Rollnick, 2001; Miller & Rose, 2009). The specific description of motivational interviewing varies slightly among the papers; however, a constant feature is that the techniques of the method are subordinated the spirit: “Motivational interviewing without this underlying spirit is no longer motivational interviewing” (Miller & Rose, 2009:535). From the three papers, we derived the keywords that characterize the spirit and the techniques of motivational interviewing to be used as a framework in the analysis. Methodology/methods (max 700) – 696 with spaces The study was planned and carried out according to recommended stages of qualitative research interviewing (Kvale & Brinkmann, 2009). We conducted semi-structured, in-depth interviews with a purposive sample of twelve school nurses from twelve schools. The nurses were asked to bring three to four child records as cases for stimulated recall during the interview. The interviews lasted approximately one and a half hour and were audio recorded and transcribed verbatim. The interview material was coded and analysed in two steps: First, openly for what data told about motivational interviewing. Next, specifically according to the keywords of the motivational interviewing spirit and techniques. Key results (max 1500) pt. 965 The study showed that the motivational interviewing spirit and techniques are integrated, inseparable, and adapted by the school nurses. An example is to use the BMI-curve as a tool to inform about the overweight, and to use it with the spirit of motivational interviewing for evoking the child’s own concern, as illustrated in the following quote: “I show the BMI-curve and the dot where the child is placed on the curve. The goal is to make the child talk. Often they have noticed the overweight themselves and are concerned”. The study revealed three dilemmas with motivational interviewing for obesity prevention in children: when the parents did not perceive the child’s overweight as a problem, when the child and the parents were at different stages of motivation to change, and when an applying individualizing approach as motivational interviewing to a complex societal problem such a

    1997-01-01

    During the Bicentennial summer of 1976, American Legion Conventioneers in Philadelphia suffered a dramatic epidemic that left 34 dead. Near the end of 1976, scientists at the Centers for Disease Control (CDC) in Atlanta discovered the bacterium that caused Legionnaires` disease and named it Legionella. Nearly two decades later, a wealth of scientific information exists about the organism, its health effects, epidemiology, microbiology, aquatic ecology, molecular biology, immunology, pathophysiology, etc. Fortunately, for the engineer seeking to prevent Legionnaires` disease, it is unnecessary to master this complexity; the practice of prevention requires understanding a few, straightforward facts. The purpose of this paper is to present four messages about Legionnaires` disease that provide a conceptual framework to guide the crucial role of practical prevention. Those messages are: Legionnaires` disease is important; Legionnaires` disease is an environmental disease; Legionnaires` disease is preventable; and Legionnaires` disease prevention requires the right strategy.

    The ToyBox intervention was developed using an evidence-based approach, using the findings of four reviews. These reviews included three critical and narrative reviews of educational strategies and psychological approaches explaining young children's acquisition and formation of energy-balance related behaviours, and the management of these behaviours, and also a systematic review of behavioural models underpinning school-based interventions in preschool and school settings for the prevention of obesity in children aged 4-6 years. This paper summarises and translates the findings from these reviews into practical evidence based recommendations for researchers and policy-makers to consider when developing and implementing interventions for the prevention of overweight and obesity in young (aged 4-6 years) children. The recommendations focus on two behaviours, physical activity and sedentary behaviour, and healthy eating, and include general recommendations, intervention approaches, interventions content, and simple messages. The review also briefly examines the role that the commercial sector plays in hindering or facilitating attempts to create healthy food environments for children. This paper also recognises that childhood obesity is not an issue for the education sector alone; it needs to be tackled at a multi sectoral level, recognizing the particularly important role of local governments, nongovernment organizations and the media.

  1. Taxation as prevention and as a treatment for obesity: the case of sugar-sweetened beverages.

    The contemporary American food environment makes energy-dense, nutrient-poor foods and beverages the "default" option for most consumers. Economic interventions like taxes can shift the relative prices of unhealthy foods to nudge consumers towards healthier options. Beverages with added sugar are a good starting point for food taxation; they constitute over 10 percent of caloric intake nationwide and provide little or no nutritional value. Current levels of taxation on sugar-sweetened beverages (SSBs) are too low to affect consumer behavior, but the implementation of a penny-per-ounce excise tax could lead to substantial public health benefits. Current estimates predict that a tax that raised the cost of SSBs by 20 percent could lead to an average reduction of 3.8 pounds per year for adults, causing the prevalence of obesity to decline from 33 to 30 percent. SSB taxes would also generate considerable revenue for public health and obesity prevention programs. Although the beverage industry is fighting such taxes with massive lobbying and public relations campaigns, support for the policies is increasing, especially when revenue is earmarked for obesity prevention.

    With obesity affecting approximately 12.5 million American youth, population-level interventions are indicated to help support healthy behaviors. The purpose of this review is to provide a summary of population-level intervention strategies and specific intervention examples that illustrate ways to help prevent and control obesity in children through improving nutrition and physical activity behaviors. Information is summarized within the settings where children live, learn, and play (early care and education, school, community, health care, home). Intervention strategies are activities or changes intended to promote healthful behaviors in children. They were identified from (a) systematic reviews; (b) evidence- and expert consensus-based recommendations, guidelines, or standards from nongovernmental or federal agencies; and finally (c) peer-reviewed synthesis reviews. Intervention examples illustrate how at least one of the strategies was used in a particular setting. To identify interventions examples, we considered (a) peer-reviewed literature as well as (b) additional sources with research-tested and practice-based initiatives. Researchers and practitioners may use this review as they set priorities and promote integration across settings and to find research- and practice-tested intervention examples that can be replicated in their communities for childhood obesity prevention.

    This article discusses how legal rights-based discourse could inform the response of Australian State and federal governments to the increasing prevalence of childhood obesity. The authors contend that the principles in the United Nations Convention on the Rights of the Child (a treaty which has been ratified but not implemented) are capable of providing a basis for a legislative program to prevent childhood obesity. It is argued that an approach to legislation which is grounded on the basis of children's rights would require that there be restrictions on advertising food to children. The authors set out specific proposals for legislative reforms which the federal Parliament could enact to implement the Convention so as to restrict advertising to children. The scope of the discussion is then expanded to consider the implications of rights-based discourse in broader public health contexts. PMID:18807794

    Full Text Available Abstract Background Obesity is a major risk factor for many diseases. The paper calculates the economic impact and the cost per Quality-Adjusted Life Year (QALY resulting from the adoption of eight interventions comprising the clinical and part of the community components of the National Prevention and Health Promotion Program (NPHPP of the Israeli Ministry of Health (MOH which represents the obesity control implementation arm of the MOH Healthy Israel 2020 Initiative. Methods Health care costs per person were calculated by body mass index (BMI by applying Israeli cost data to aggregated results from international studies. These were applied to BMI changes from eight intervention programmes in order to calculate reductions in direct treatment costs. Indirect cost savings were also estimated as were additional costs due to increased longevity of program participants. Data on costs and QALYs gained from Israeli and International dietary interventions were combined to provide cost-utility estimates of an intervention program to reduce obesity in Israel over a range of recidivism rates. Results On average, persons who were overweight (25 ? BMI For overweight (25 ? BMI A program directed at the entire Israeli population aged 20 and over, using a variety of eight different interventions would cost 2.07 billion NIS overall. In the baseline scenario (with an assumed recidivism rate of 50% per annum, approximately 620,000,000 NIS would be recouped in the form of decreased treatment costs and indirect costs, increased productivity and decreased absenteeism. After discounting the 89,000,000 NIS additional health costs attributable to these extra life years, it is estimated that the total net costs to society would be 1.55 billion NIS. This total net cost was relatively stable to increases in the program's recidivism rates, but highly sensitive to reductions in recidivism rates. Under baseline assumptions, implementation of the cluster of interventions would save 32,671 discounted QALYs at a cost of only 47,559 NIS per QALY, less than half of the Israeli per capita GNP (104,000 NIS. Thus implementation of these components of the NPHPP should be considered very cost-effective. Conclusion Despite the large costs of such a large national program to control obesity, cost-utility analysis strongly supports its introduction.

    Full Text Available Objective Evaluate the effect of glycemic index (GI) on biochemical parameters, food intake, energy metabolism, anthropometric measures and body composition in overweight subjects.Materials and methods Simple blind study, in which nineteen subjects were randomly assigned to consume in the laboratory [...] two daily low GI (n = 10) or high GI (n = 9) meals, for forty-five consecutive days. Habitual food intake was assessed at baseline. Food intake, anthropometric measures and body composition were assessed at each 15 days. Energy metabolism and biochemical parameters were evaluated at baseline and the end of the study.Results Low GI meals increased fat oxidation, and reduced waist circumference and HOMA-IR, while high GI meals increased daily dietary fiber and energy intake compared to baseline. There was a higher reduction on waist circumference and body fat, and a higher increase on postprandial fat oxidation in response to the LGI meals than after high GI meals. High GI meals increased fasting respiratory coefficient compared to baseline and low GI meals.Conclusion The results of the present study showed that the consumption of two daily low GI meals for forty-five consecutive days has a positive effect on obesity control, whereas, the consumption of high GI meals result has the opposite effect.

  9. Deletion of skeletal muscle SOCS3 prevents insulin resistance in obesity

    DEFF Research Database (Denmark)

    Beck JØrgensen, Sebastian; O'Neill, Hayley M

    2013-01-01

    Obesity is associated with chronic low-grade inflammation that contributes to defects in energy metabolism and insulin resistance. Suppressor of cytokine signaling (SOCS)-3 expression is increased in skeletal muscle of obese humans. SOCS3 inhibits leptin signaling in the hypothalamus and insulin signal transduction in adipose tissue and the liver. Skeletal muscle is an important tissue for controlling energy expenditure and whole-body insulin sensitivity; however, the physiological importance of SOCS3 in this tissue has not been examined. Therefore, we generated mice that had SOCS3 specifically deleted in skeletal muscle (SOCS MKO). The SOCS3 MKO mice had normal muscle development, body mass, adiposity, appetite, and energy expenditure compared with wild-type (WT) littermates. Despite similar degrees of obesity when fed a high-fat diet, SOCS3 MKO mice were protected against the development of hyperinsulinemia and insulin resistance because of enhanced skeletal muscle insulin receptor substrate 1 (IRS1) and Akt phosphorylation that resulted in increased skeletal muscle glucose uptake. These data indicate that skeletal muscle SOCS3 does not play a critical role in regulating muscle development or energy expenditure, but it is an important contributing factor for inhibiting insulin sensitivity in obesity. Therapies aimed at inhibiting SOCS3 in skeletal muscle may be effective in reversing obesity-related glucose intolerance and insulin resistance.

    Taurine (Tau) regulates ?-cell function and glucose homeostasis under normal and diabetic conditions. Here, we assessed the effects of Tau supplementation upon glucose homeostasis and the morphophysiology of endocrine pancreas, in leptin-deficient obese (ob) mice. From weaning until 90-day-old, C57Bl/6 and ob mice received, or not, 5% Tau in drinking water (C, CT, ob and obT). Obese mice were hyperglycemic, glucose intolerant, insulin resistant, and exhibited higher hepatic glucose output. Tau supplementation did not prevent obesity, but ameliorated glucose homeostasis in obT. Islets from ob mice presented a higher glucose-induced intracellular Ca(2+) influx, NAD(P)H production and insulin release. Furthermore, ?-cells from ob islets displayed a higher oscillatory Ca(2+) profile at low glucose concentrations, in association with glucagon hypersecretion. In Tau-supplemented ob mice, insulin and glucagon secretion was attenuated, while Ca(2+) influx tended to be normalized in ?-cells and Ca(2+) oscillations were increased in ?-cells. Tau normalized the inhibitory action of somatostatin (SST) upon insulin release in the obT group. In these islets, expression of the glucagon, GLUT-2 and TRPM5 genes was also restored. Tau also enhanced MafA, Ngn3 and NeuroD mRNA levels in obT islets. Morphometric analysis demonstrated that the hypertrophy of ob islets tends to be normalized by Tau with reductions in islet and ?-cell masses, but enhanced ?-cell mass in obT. Our results indicate that Tau improves glucose homeostasis, regulating ?-, ?-, and ?-cell morphophysiology in ob mice, indicating that Tau may be a potential therapeutic tool for the preservation of endocrine pancreatic function in obesity and diabetes.

    Population-wide obesity prevention and treatment programs are fundamental to addressing the increasing overweight and obesity rates in socioeconomically disadvantaged populations. Innovative recruitment strategies, including proactive marketing strategies, are needed to ensure such programs have universal reach and target vulnerable populations. This study aimed to determine the success of proactive recruitment to Australia's Get Healthy Information and Coaching Service® (GHS) and to assess whether the recruitment strategy influenced participants' outcomes. Sociodemographic information was collected from all GHS participants who joined the service between February 2009 and August 2013, and anthropometric information regarding behavioural risk factors was collected from all GHS coaching participants at baseline and six months. Data were analysed according to the participants' referral source (self-referral and secondary referral versus proactive recruitment). Participants recruited through proactive marketing were more likely to be male, aged 50 years or older, have high school education, not be in paid employment and be from the lowest three quintiles of socioeconomic advantage. The risk factor profile of coaching participants recruited through proactive marketing did not vary significantly from those recruited via other mechanisms, although they were less likely to be obese and less likely to have a higher 'at risk' waist circumference measurement. Proactively recruited coaching participants reported significant improvements from baseline to six months (consistent with improvements made by participants recruited through other strategies), although they were significantly more likely to withdraw from coaching before they completed the six-month program.Proactive marketing facilitated use of an obesity prevention service; similar services may have greater reach if proactive marketing recruitment strategies are used. These strategies could be encouraged to assist such services to achieve optimal population impact among hard-to-reach populations. PMID:25848739

    We use National Longitudinal Survey of Youth (NLSY) data to examine the effects of obesity on wages by gender. Sample means indicate that both men and women experience a persistent obesity wage penalty over the first two decades of their careers. We then control for a standard set of socioeconomic and familial variables but find that standard covariates do not explain why obese workers experience persistent wage penalties. This suggests that other variables -- including job discrimination, health-related factors and/or obese workers' behavior patterns -- may be the channels through which obesity adversely affects wages. The study closes with a discussion of the public policy implications suggested by these findings. PMID:15362180

    A Mediterranean diet rich in olive oil has profound influence on health outcomes including metabolic syndrome. However, the active compound and detailed mechanisms still remain unclear. Hydroxytyrosol (HT), a major polyphenolic compound in virgin olive oil, has received increased attention for its antioxidative activity and regulation of mitochondrial function. Here, we investigated whether HT is the active compound in olive oil exerting a protective effect against metabolic syndrome. In this study, we show that HT could prevent high-fat-diet (HFD)-induced obesity, hyperglycemia, hyperlipidemia, and insulin resistance in C57BL/6J mice after 17 weeks supplementation. Within liver and skeletal muscle tissues, HT could decrease HFD-induced lipid deposits through inhibition of the SREBP-1c/FAS pathway, ameliorate HFD-induced oxidative stress by enhancing antioxidant enzyme activities, normalize expression of mitochondrial complex subunits and mitochondrial fission marker Drp1, and eventually inhibit apoptosis activation. Moreover, in muscle tissue, the levels of mitochondrial carbonyl protein were decreased and mitochondrial complex activities were significantly improved by HT supplementation. In db/db mice, HT significantly decreased fasting glucose, similar to metformin. Notably, HT decreased serum lipid, at which metformin failed. Also, HT was more effective at decreasing the oxidation levels of lipids and proteins in both liver and muscle tissue. Similar to the results in the HFD model, HT decreased muscle mitochondrial carbonyl protein levels and improved mitochondrial complex activities in db/db mice. Our study links the olive oil component HT to diabetes and metabolic disease through changes that are not limited to decreases in oxidative stress, suggesting a potential pharmaceutical or clinical use of HT in metabolic syndrome treatment.

    Obesity, especially visceral adiposity, is associated with morbidity and mortality through endocrine and mechanical processes. Clinical manifestations due to effects of obesity on the cardiovascular, respiratory, gastrointestinal, musculoskeletal, immune, and integumentary systems have been described. Further studies are needed to understand the pathologic processes underlying these clinical manifestations to improve disease prevention. PMID:19501243

    Full Text Available Abstract Background Efforts to prevent the development of overweight and obesity have increasingly focused early in the life course as we recognise that both metabolic and behavioural patterns are often established within the first few years of life. Randomised controlled trials (RCTs of interventions are even more powerful when, with forethought, they are synthesised into an individual patient data (IPD prospective meta-analysis (PMA. An IPD PMA is a unique research design where several trials are identified for inclusion in an analysis before any of the individual trial results become known and the data are provided for each randomised patient. This methodology minimises the publication and selection bias often associated with a retrospective meta-analysis by allowing hypotheses, analysis methods and selection criteria to be specified a priori. Methods/Design The Early Prevention of Obesity in CHildren (EPOCH Collaboration was formed in 2009. The main objective of the EPOCH Collaboration is to determine if early intervention for childhood obesity impacts on body mass index (BMI z scores at age 18-24 months. Additional research questions will focus on whether early intervention has an impact on children's dietary quality, TV viewing time, duration of breastfeeding and parenting styles. This protocol includes the hypotheses, inclusion criteria and outcome measures to be used in the IPD PMA. The sample size of the combined dataset at final outcome assessment (approximately 1800 infants will allow greater precision when exploring differences in the effect of early intervention with respect to pre-specified participant- and intervention-level characteristics. Discussion Finalisation of the data collection procedures and analysis plans will be complete by the end of 2010. Data collection and analysis will occur during 2011-2012 and results should be available by 2013. Trial registration number ACTRN12610000789066

    2014-08-01

    Exergames have started to find their way into field-based settings, such as schools, communities and homes, as a possible solution to curbing physical inactivity and childhood obesity. However, a clear view of the effects of field-based exergaming on children's obesity-related outcomes is lacking. Hence, a systematic review on this topic is warranted. This review synthesizes the impact of field-based exergames on children's physical and psychosocial outcomes. A total of 34 articles conducted in field-based settings were identified from 104 peer-reviewed publications that investigated the effects of exergames. Upon screening, these articles met the inclusion criteria and a high inter-rater agreement for inclusion was reached between the authors. The effects of field-based exergames on children's habitual physical activity (PA) and obesity-related outcomes (e.g. weight loss, body composition) remain unclear due to design problems, measurement issues and other methodology concerns. In addition, exergame is appealing to children, although strategies are warranted to sustain their interests. In summary, exergames are desirable as a promising addition to promote PA and health. Professionals may integrate exergames at field settings to promote a physically active lifestyle among children with the goal of curbing childhood obesity. PMID:24602072

    2009-05-01

    Full Text Available Introduction: The intragastric balloon is a minimally invasive technique used to treat obesity by reducing hunger and inducing satiety as a result of gastric volume restriction, thus it could be ideal to treat young people who are thought to be easier to change their eating behavior. Aim: The purpose of this prospective clinical study was to investigate the effectiveness of intragastric balloon on obese adolescents, after a six-month period of treatment. Material: Fourteen adolescents -aged 18,5±2,5 yrs- treated by intragastric balloon were studied prospectively. Mean baseline Body Mass Index [BMI] was 39,8 ± 5,8kg/m2 and %Fatty Mass [FM] 41,7 ± 5,4. The data collected every month for the 6mo period was: Body Weight [BW], BMI, Resting metabolic Rate [RMR] by indirect calorimetry, %FM, %Excessive Weight Loss [%EWL] and %Actual Caloric Intake [%ACI]. Appetite related sensations scores [hunger, satiety, desire for food] were also assessed monthly by visual analogue scales [VAS]. The number of follow-up visits was considered as a marker of compliance. Results: Median baseline values were as follows: BM 118kg [range 80 to 174], BMI 39,1kg/m2 [range 33 to 54] [>95th percentile],%FM 42 [range 33 to 49] and %ACI 116,6 [range 60 to 200,5]. After a 6mo period, just before the removal of the balloon, all measured parameters exhibited a statistically significant reduction: the median BW was found to be 108kg [range 62 to 162, p=0,002], the BMI 37kg/m2 [range 26 to 50, p=0,001], %FM 40 [range 20 to 49, p=0,009], the %EWL was 14,29 [range 3,33 to 69,23, p=0,021] and the %ACI=86 [range 33 to 153,96, p=0,02]. Appetite related sensation score was unchanged.The median number of follow-up visits was 4 [range 2 to 7]. Conclusions: Although the number of follow-up visits during the 6 month treatment generally reveals poor compliance,a small though significant weight loss, as a consequence of reduction in the energy intake is prominent. Based on the above findings, a better pre-procedure screening for the appropriate candidates for treatment as well as a better scheduled approach by a multi-disciplinary group, including a dietician and a psychologist is considered mandatory.

    Full Text Available Abstract Background Dietary 1(3-behenoyl-2,3(1-dioleoyl-rac-glycerol (BOO has been reported to inhibit pancreatic lipase activity in vitro and suppress postprandial hypertriacylglycerolemia in humans. In the present study, the anti-obesity activities of BOO and its inhibitory effects on lymphatic triacylglycerol (TAG absorption were investigated in rats. Methods In Experiment 1, rats were fed either BOO or soybean oil (SO diet for 6 weeks. In the BOO diet, 20% of SO was replaced with an experimental oil rich in BOO. In Experiments 2 and 3, rats cannulated in the thoracic duct were administered an emulsions containing trioleoylglycerol (OOO or an oil mixture (OOO:BOO, 9:1. Tri[1-14C]oleoylglycerol (14C-OOO was added to the emulsions administered in Experiment 3. Results No observable differences were detected in food intake or body weight gain between the BOO and SO groups in Experiment 1. Plasma and liver TAG concentrations and visceral fat weights were significantly lower in the BOO group than in the SO group. The apparent absorption rate of fat was significantly lower in the BOO group than in the SO group. In Experiment 2, the lymphatic recovery of oleic and behenic acids was significantly lower at 5 and 6 h after BOO administration than after OOO administration. In Experiment 3, the lymphatic recovery of 14C-OOO was significantly lower at 5 and 6 h after BOO administration than after OOO administration. Conclusions These results suggest that BOO prevents deposition of visceral fat and hepatic TAG by lowering and delaying intestinal absorption of TAG.

  4. Personal responsibility or shared responsibility: What is the appropriate role of the law in obesity prevention?

    Science.gov (United States)

    Brooks, Benjamin

    2015-09-01

    Sensitive to allegations of "nanny state" paternalism, Australian governments support the doctrine that combating obesity is a matter of personal responsibility. Policy-makers endorse the "holistic" approach to obesity prevention, with a view to managing both sides of the nutritional energy equation. This paradigm allows the food and drinks industry to deflect its contributory responsibility for the epidemic and to avoid more stringent regulatory intervention beyond existing self-regulatory and corporate social responsibility regimes. This article argues that the industry must bear shared responsibility for the extent of the obesity crisis, although it cannot bear sole responsibility It defends the public interest case for more invasive, government-led regulation, reframing the crisis as one of public not individual burdens. Mindful of the political risk associated with unfocused calls for regulatory intervention, it articulates a set of regulatory principles to ensure that the interests of consumers and industry are properly acknowledged prior to further regulatory intervention. Finally, the article clarifies the subject, object and content of possible regulatory initiatives, offering an evaluation of their efficacy, practicality and fairness. PMID:26554202

    2015-03-01

    Full Text Available OBJECTIVE: To review the current literature concerning the effects of physical exercise on several metabolic variables related to childhood obesity. DATA SOURCE: A search was performed in Pubmed/MEDLINE and Web of Science databases. The keywords used were as follows: Obesity, Children Obesity, Childhood Obesity, Exercise and Physical Activity. The online search was based on studies published in English, from April 2010 to December 2013. DATA SYNTHESIS: Search queries returned 88,393 studies based on the aforementioned keywords; 4,561 studies were selected by crossing chosen keywords. After applying inclusion criteria, four studies were selected from 182 eligible titles. Most studies found that aerobic and resistance training improves body composition, lipid profile and metabolic and inflammatory status of obese children and adolescents; however, the magnitude of these effects is associated with the type, intensity and duration of practice. CONCLUSIONS: Regardless of the type, physical exercise promotes positive adaptations to childhood obesity, mainly acting to restore cellular and cardiovascular homeostasis, to improve body composition, and to activate metabolism; therefore, physical exercise acts as a co-factor in fighting obesity.

    2010-08-01

    Full Text Available Abstract Background Obesity is a major public health issue; however, only limited evidence is available about effective ways to prevent obesity, particularly in early childhood. Romp & Chomp was a community-wide obesity prevention intervention conducted in Geelong Australia with a target group of 12,000 children aged 0-5 years. The intervention had an environmental and capacity building focus and we have recently demonstrated that the prevalence of overweight/obesity was lower in intervention children, post-intervention. Capacity building is defined as the development of knowledge, skills, commitment, structures, systems and leadership to enable effective health promotion and the aim of this study was to determine if the capacity of the Geelong community, represented by key stakeholder organisations, to support healthy eating and physical activity for young children was increased after Romp & Chomp. Methods A mixed methods evaluation with three data sources was utilised. 1 Document analysis comprised assessment of the documented formative and intervention activities against a capacity building framework (five domains: Partnerships, Leadership, Resource Allocation, Workforce Development, and Organisational Development; 2 Thematic analysis of key informant interviews (n = 16; and 3 the quantitative Community Capacity Index Survey. Results Document analysis showed that the majority of the capacity building activities addressed the Partnerships, Resource Allocation and Organisational Development domains of capacity building, with a lack of activity in the Leadership and Workforce Development domains. The thematic analysis revealed the establishment of sustainable partnerships, use of specialist advice, and integration of activities into ongoing formal training for early childhood workers. Complex issues also emerged from the key informant interviews regarding the challenges of limited funding, high staff turnover, changing governance structures, lack of high level leadership and unclear communication strategies. The Community Capacity Index provided further evidence that the project implementation network achieved a moderate level of capacity. Conclusions Romp & Chomp increased the capacity of organisations, settings and services in the Geelong community to support healthy eating and physical activity for young children. Despite this success there are important learnings from this mixed methods evaluation that should inform current and future community-based public health and health promotion initiatives.

    The prevalence and incidence of overweight and obesity has been studied in a young adult population aged 19-35 years. Special attention was given to the relation with psychosociological variables and life-style. The prevalence of overweight and obesity was also studied in a representative population for The Netherlands, in which population also the relation with self-reported illness and subjective health was studied. In the patient population of four general practices the relation of overweight and obesity with disease was investigated in a retrospective design. Also the influence of the body fat distribution was studied. The prevalence of overweight (BMI greater than 25 kg/m2) in the Dutch adult population was 34% in men and 24% in women. The prevalence of obesity (BMI greater than 30 kg/m2) was 4 and 6% in men and women, respectively. The prevalence of overweight and obesity was negatively related with social class and increased with age. Also, life-style variables such as coffee consumption, alcohol consumption, smoking and amount of hours sleep (CASS behavior), physical activity during leisure time, slimming behavior and health-conscious behavior were correlated with the prevalence of overweight. Life events caused an increase in body weight, but in women (not in men) this gain was suppressed by following slimming periods. Thus, emotional eating seems to be an important factor in the etiology of obesity. The results of our studies on the relation of overweight and obesity with morbidity aspects show a clear relation of some diseases and subjective health with overweight, especially in men and women with an abdominal fat distribution. From the results of this study starting points for the prevention and treatment of obesity are proposed. PMID:2675827

    Full Text Available Abstract Background Schools are the most frequent target for intervention programs aimed at preventing child obesity; however, the overall effectiveness of these programs has been limited. It has therefore been recommended that interventions target multiple ecological levels (community, family, school and individual to have greater success in changing risk behaviors for obesity. This study examined the immediate and short-term, sustained effects of the Switch program, which targeted three behaviors (decreasing children's screen time, increasing fruit and vegetable consumption, and increasing physical activity at three ecological levels (the family, school, and community. Methods Participants were 1,323 children and their parents from 10 schools in two states. Schools were matched and randomly assigned to treatment and control. Measures of the key behaviors and body mass index were collected at baseline, immediately post-intervention, and 6 months post-intervention. Results The effect sizes of the differences between treatment and control groups ranged between small (Cohen's d = 0.15 for body mass index at 6 months post-intervention to large (1.38; parent report of screen time at 6 months post-intervention, controlling for baseline levels. There was a significant difference in parent-reported screen time at post-intervention in the experimental group, and this effect was maintained at 6 months post-intervention (a difference of about 2 hours/week. The experimental group also showed a significant increase in parent-reported fruit and vegetable consumption while child-reported fruit and vegetable consumption was marginally significant. At the 6-month follow-up, parent-reported screen time was significantly lower, and parent and child-reported fruit and vegetable consumption was significantly increased. There were no significant effects on pedometer measures of physical activity or body mass index in the experimental group. The intervention effects were moderated by child sex (for fruit and vegetable consumption, physical activity, and weight status, family involvement (for fruit and vegetable consumption, and child body mass index (for screen time. The perception of change among the experimental group was generally positive with 23% to 62% indicating positive changes in behaviors. Conclusion The results indicate that the Switch program yielded small-to-modest treatment effects for promoting children's fruit and vegetable consumption and minimizing screen time. The Switch program offers promise for use in youth obesity prevention.

    Full Text Available Objective : The aim of this study was to evaluate the late effects of maternal obesity induced by lesion of the ventromedial hypothalamus on offspring metabolism.Materials and methods : Thirty days after the bilateral lesion of the ventromedial hypothalamus, female rats were mated and divided into 2 groups of pregnant animals: Control (C – false lesion (sham and Obese (OB – lesion. Three months after that, with the groups of mothers, offspring were divided into control and obese animals that received a normocaloric diet (C-N and OB-N, and control and obese animals that received a hypercaloric diet (C-H and OB-H. At 120 days of age, the animals were euthanized and their carcasses, feces and food were submitted to calorimetric analysis to determine energy balance and body composition.Results : During the growth period, offspring from obese mothers showed higher values of body weight and food intake than controls. Obese animals showed higher body weight gain and gross food efficiency than control animals in adulthood. The hypercaloric diet led to increased metabolizable energy intake, percentage of absorbed energy and energy expenditure in both groups. Body composition was only affected by the association of hypercaloric diet and maternal obesity that led to increased body fat.Conclusions : Maternal obesity has led to the development of later overweight in offspring, suggesting fetal programming. According to the trend presented, it is believed that the prolonged intake of hypercaloric diets in adult animals may, as an additional effect, induce worsening of the overweight induced by maternal obesity.

    2015-01-01

    Obesity is a strong risk factor for hypertension, but the mechanism linking obesity to hypertension is not fully elucidated. In obesity, circulating concentrations of adiponectin are decreased and hypoadiponectinaemia has in some but not all studies been associated with increased risk of hypertension. Due to this inconsistency, we decided to study adiponectin from two aspects in a cross-sectional in vivo study and in an experimental in vitro study. In the cross-sectional study, 103 men with body mass index (BMI) ? 30.0 kg/m(2) were studied; 63 had 24-hr ambulatory blood pressure (ABP) ? 130/80 mmHg (ObeseHT) and 40 had 24-hr ABP < 130/80 mmHg (ObeseNT). As controls, we studied 27 men with BMI between 20.0 and 24.9 kg/m(2) and 24-hr ABP < 130/80 mmHg (LeanNT). Serum concentrations of adiponectin and body composition using dual-energy X-ray absorptiometry scanning were determined. In vitro, the direct vasomotor response of adiponectin was tested on subcutaneous resistance arteries from human abdominal adipose tissue. The two obese groups had lower adiponectin concentrations compared with LeanNT (p < 0.01) [median (interquartile range)]: ObeseHT 6.5 (5.1-8.3) mg/L; ObeseNT 6.6 (5.2-7.8) mg/L; and LeanNT 9.4 (6.7-12.4) mg/L, with no significant difference in adiponectin concentrations (or body composition) between ObeseHT and ObeseNT (p = 0.67). In vitro, adiponectin did not have any direct vasodilatory effect and adiponectin did not affect angiotensin II-stimulated vasoconstriction. In conclusion, obese hypertensive men have similar serum concentrations of adiponectin as obese normotensive men. In combination with the in vitro data, these findings question a pathogenic role of adiponectin in human hypertension.

    Full Text Available The interest in genetic manipulations of PPARs is as old as their discovery as receptors of ligands with beneficial clinical activities. Considering the effects of PPAR ligands on critical aspects of systemic physiology, including obesity, lipid metabolism, insulin resistance, and diabetes, gene knockout (KO in mice is the ideal platform for both hypothesis testing and discovery of new PPAR functions in vivo. With the fervent pursuit of the magic bullet to eradicate the obesity epidemic, special emphasis has been placed on the impacts of PPARs on obesity and its associated diseases. As detailed in this review, understanding how PPARs regulate gene expression and basic metabolic pathways is a necessary intermediate en route to deciphering their effects on obesity. Over a decade and dozens of genetic modifications of PPARs into this effort, valuable lessons have been learned, but we are left with more questions to be answered. These lessons and future prospects are the subject of this review.

    Background The aim of this study was to analyze the effects of obesity and leptin levels on patients with migraine, and to observe the change of leptin levels in migraineurs. Material/Methods We enrolled 52 migraine patients from the Headache Clinic in Shandong Provincial Hospital into a randomized controlled trial with another 52 age-, sex-, and BMI-matched healthy subjects as controls. Leptin levels in all subjects were determined by radioimmunoassay. Results Compared with the control group, the migraineurs revealed no significant change in leptin levels (P>0.05). Multivariate Logistic regression analysis showed that neither abdominal obesity nor leptin had significant impact on migraine clinical features. Total body obesity had a significant effect on the frequency (OR=4.248), duration (OR=3.167), and intensity (OR=5.225) of the headache. Conclusions Total body obesity affected headache frequency, intensity, and duration, while leptin levels did not. PMID:26508370

    The prevention of childhood obesity is a global priority. However, a range of complex social and environmental influences is implicated in the development of obesity and chronic disease that goes beyond the notion of individual choice. A population-level approach recognises the importance of access to and availability of healthy foods outside the home. These external food environments, in restaurants, supermarkets, and in school, or recreation and sports settings, are often characterised by energy dense, nutrient-poor food items that do not reflect the current nutritional guidelines for health. In addition, our understanding of these broader influences on nutritional intake is still limited. Particularly, lacking is a clear understanding of what constitutes the food environment, as well as robust measures of components of the food environment across different contexts. Therefore, this review summarises the literature on food environments of relevance to childhood obesity prevention, with a focus on places where children live, learn and play. Specifically, the paper highlights the approaches and challenges related to defining and measuring the food environment, discusses the aspects of the food environment unique to children and reports on environmental characteristics that are being modified within community, school and recreational settings. Results of the review show the need for a continued focus on understanding the intersection between individual behaviour and external factors; improved instrument development, especially regarding validity and reliability; clearer reported methodology including protocols for instrument use and data management; and considering novel study design approaches that are targeted at measuring the relationship between the individual and their food environment.

    The prevalence of obesity is increasing globally, and obesity is a major risk factor for metabolic diseases such as type 2 diabetes. Previously, we reported that oral administration of homobrassinolide (HB) to healthy rats triggered a selective anabolic response that was associated with lower blood glucose. Therefore, the aim of this study was to evaluate the effects of HB administration on glucose metabolism, insulin sensitivity, body composition, and gluconeogenic gene expression profiles i...

    Childhood obesity is one of the most important issues in Public Health so that the adoption of innovative preventive integrated approaches is increasingly needed. The presence of coordinated and integrated programmes, aimed at preventing childhood obesity and based on innovative large-scale approaches, was ascertained by means of a literature search. In Europe three programmes, with activities and staff characterized by common aims and active participation of different stakeholders, use such a community-based approach, which allowed changes in physical and social environment, resulting in new and innovative elements for lifestyle modifications.

  5. The Effects of Obesity on Murine Cortical Bone

    Science.gov (United States)

    Martin, Sophi

    This dissertation details the effects of obesity on the mechanical properties and structure of cortical bone. Obesity is associated with greater bone mineral content that might be expected to protect against fracture, which has been observed in adults. Paradoxically however, the incidence of bone fractures has been found to increase in overweight and obese children and adolescents. Femora from adolescent and adult mice fed a high-fat diet are investigated for changes in shape, tissue structure, as well as tissue-level and whole-bone mechanical properties. Results indicate increased bone size, reduced size-independent mechanical properties, but maintained size-dependent mechanical properties. Other changes in cortical bone response to obesity are observed with advancing age. This study indicates that bone quantity and bone quality play important compensatory roles in determining fracture risk, and that fracture risk may not be lessened for adults as previously thought.

    Full Text Available Abstract Background Parents are integral to the implementation of obesity prevention and management recommendations for children. Exploration of barriers to and facilitators of parental decisions to adopt obesity prevention recommendations will inform future efforts to reduce childhood obesity. Methods We conducted 4 focus groups (2 English, 2 Spanish among a total of 19 parents of overweight (BMI ? 85th percentile children aged 5-17 years. The main discussion focused on 7 common obesity prevention recommendations: reducing television (TV watching, removing TV from child's bedroom, increasing physically active games, participating in community or school-based athletics, walking to school, walking more in general, and eating less fast food. Parents were asked to discuss what factors would make each recommendation more difficult (barriers or easier (facilitators to follow. Participants were also asked about the relative importance of economic (time and dollar costs/savings barriers and facilitators if these were not brought into the discussion unprompted. Results Parents identified many barriers but few facilitators to adopting obesity prevention recommendations for their children. Members of all groups identified economic barriers (time and dollar costs among a variety of pertinent barriers, although the discussion of dollar costs often required prompting. Parents cited other barriers including child preference, difficulty with changing habits, lack of information, lack of transportation, difficulty with monitoring child behavior, need for assistance from family members, parity with other family members, and neighborhood walking safety. Facilitators identified included access to physical activity programs, availability of alternatives to fast food and TV which are acceptable to the child, enlisting outside support, dietary information, involving the child, setting limits, making behavior changes gradually, and parental change in shopping behaviors and own eating behaviors. Conclusions Parents identify numerous barriers to adopting obesity prevention recommendations, most notably child and family preferences and resistance to change, but also economic barriers. Intervention programs should consider the context of family priorities and how to overcome barriers and make use of relevant facilitators during program development.

    Full Text Available Abstract Background There is a strong rationale for intervening in early childhood to prevent obesity. Over a quarter of infants gain weight more rapidly than desirable during the first six months of life putting them at greater risk of obesity in childhood. However, little is known about UK healthcare professionals' (HCPs approach to primary prevention. This study explored obesity-related knowledge of UK HCPs and the beliefs and current practice of general practitioners (GPs and practice nurses in relation to identifying infants at risk of developing childhood obesity. Method Survey of UK HCPs (GPs, practice nurses, health visitors, nursery, community and children's nurses. HCPs (n = 116 rated their confidence in providing infant feeding advice and completed the Obesity Risk Knowledge Scale (ORK-10. Semi-structured interviews with a sub-set of 12 GPs and 6 practice nurses were audio recorded, taped and transcribed verbatim. Thematic analysis was applied using an interpretative, inductive approach. Results GPs were less confident about giving advice about infant feeding than health visitors (p = 0.001 and nursery nurses (p = 0.009 but more knowledgeable about the health risks of obesity (p Six main themes emerged from the interviews: 1 Attribution of childhood obesity to family environment, 2 Infant feeding advice as the health visitor's role, 3 Professional reliance on anecdotal or experiential knowledge about infant feeding, 4 Difficulties with recognition of, or lack of concern for, infants "at risk" of becoming obese, 5 Prioritising relationship with parent over best practice in infant feeding and 6 Lack of shared understanding for dealing with early years' obesity. Conclusions Intervention is needed to improve health visitors and nursery nurses' knowledge of obesity risk and GPs and practice nurses' capacity to identify and manage infants' at risk of developing childhood obesity. GPs value strategies that maintain relationships with vulnerable families and interventions to improve their advice-giving around infant feeding need to take account of this. Further research is needed to determine optimal ways of intervening with infants at risk of obesity in primary care.

    Full Text Available The aim of the present study was to evaluate the effect of a 12 week program of physical exercise (PE) on butyrylcholinesterase (BChE) in obese adolescents. This study compared obese adolescents (N = 54) before and after PE, regarding the relative intensity (RI) and activity of different molecular f [...] orms (G1, G2, G4 and G1-ALB) of BChE found in plasma. Waist circumference (WC) and lipid profile were also assessed before and after PE. It was shown that before PE, mean plasma BChE activity was significantly higher in obese than in non-obese adolescents and that it was significantly reduced after PE, becoming similar to that found in non-obese adolescents. Lipid profile and WC also changed in response to PE. These results are consistent with studies that found a correlation between BChE and lipid metabolism and suggest that PE may have led to a physiological regularization of plasma BChE activity. Although mean BChE activity of each isoform was significantly reduced by PE, their RI did not change. This is in accordance with a previous suggestion that this proportion is maintained under factors such as obesity, and may therefore be important for BChE functions.

    Family-and-home-based interventions are an important vehicle for preventing childhood obesity. Systematic process evaluations have not been routinely conducted in assessment of these interventions. The purpose of this study was to plan and conduct a process evaluation of the Enabling Mothers to Prevent Pediatric Obesity Through Web-Based Learning and Reciprocal Determinism (EMPOWER) randomized control trial. The trial was composed of two web-based, mother-centered interventions for prevention of obesity in children between 4 and 6 years of age. Process evaluation used the components of program fidelity, dose delivered, dose received, context, reach, and recruitment. Categorical process evaluation data (program fidelity, dose delivered, dose exposure, and context) were assessed using Program Implementation Index (PII) values. Continuous process evaluation variables (dose satisfaction and recruitment) were assessed using ANOVA tests to evaluate mean differences between groups (experimental and control) and sessions (sessions 1 through 5). Process evaluation results found that both groups (experimental and control) were equivalent, and interventions were administered as planned. Analysis of web-based intervention process objectives requires tailoring of process evaluation models for online delivery. Dissemination of process evaluation results can advance best practices for implementing effective online health promotion programs. PMID:24648285

    Full Text Available Currently, childhood obesity is one of the most important problems in the world health since in recent years has increased significantly in developed countries. The origin of this problem is due to a lifestyle based on little or no physical activity, coupled with poor and unbalanced diet. This condition, in turn, may adversely affect the formation of students due to low self esteem, depression and other psychological problems. The measures proposed are constant to the families of the students and the students themselves, through weekly lectures and workshops, which will take place in the school itself up. In addition, another measure would be to increase the number of hours of physical activity within the school timetable, taking advantage schedules for recreation and dining.The objective of the above work is to make a proposal, as a tool to prevent and treat overweight and obesity among children from the same education.The hypothesis of the project is that the BMI of the sample of the selected school will be reduced significantly due to changes in habits, promoted from this initiative, thereby improving their school performance. No conclusive results because it has not been implemented so far. 

  7. Preventing maternal and early childhood obesity: the fetal flaw in Australian perinatal care.

    2014-01-01

    Almost half of Australian women of child-bearing age are overweight or obese, with a rate of 30-50% reported in early pregnancy. Maternal adiposity is a costly challenge for Australian obstetric care, with associated serious maternal and neonatal complications. Excess gestational weight gain is an important predictor of offspring adiposity into adulthood and higher maternal weight later in life. Current public health and perinatal care approaches in Australia do not adequately address excess perinatal maternal weight or gestational weight gain. This paper argues that the failure of primary health-care providers to offer systematic advice and support regarding women's weight and related lifestyle behaviours in child-bearing years is an outstanding 'missed opportunity' for prevention of inter-generational overweight and obesity. Barriers to action could be addressed through greater attention to: clinical guidelines for maternal weight management for the perinatal period, training and support of maternal health-care providers to develop skills and confidence in raising weight issues with women, a variety of weight management programs provided by state maternal health services, and clear referral pathways to them. Attention is also required to service systems that clearly define roles in maternal weight management and ensure consistency and continuity of support across the perinatal period. PMID:24176286

    We reexamine the effects of obesity on a wide range (n=17) of indicators of functioning drawn from five broad domains: interpersonal problems, psychological problems, suicidal behaviors, academic performance, and psychiatric disorders. Evidence on this question is mixed. Data are analyzed from a large community sample of adolescents 11-17 at baseline (n=4175) who were followed up a year later (n=3134). Using measured height and weight, overweight was defined as 95th>BMI?85th percentile and obese as BMI >95th percentile. At baseline, obesity was associated with increased odds only for any mood disorder and poor perceived mental health. For boys, there were no significant associations, but girls had higher odds of problems at school, poor perceived mental health, and mood disorders. Results from the two-wave cohort reveal obesity increased future risk only for poor perceived mental health. For boys, the same pattern was observed, but for girls there were no significant associations. Overall, we found that weight status had few deleterious effects on adolescent social functioning, in multivariate, prospective analyses. If there is an effect of obesity on functioning, it may operate through mediators such as body image. PMID:23557808

    Full Text Available Dimitrios K Papamargaritis, Dimitrios J Pournaras, Carel W Le RouxImperial Weight Centre, Imperial College London, London, UKAbstract: Obesity is an epidemic disease, and its prevalence is predicted to rise in the future. Many health and social comorbidities, such as cardiovascular disease, type 2 diabetes mellitus, cancer, nonalcoholic fatty liver disease, arthritis, infertility, eating disorders, unemployment, and low quality of life, have been associated with obesity. Nowadays, bariatric surgery is the only effective treatment for severe obesity. An increasing body of literature demonstrates significant remission of obesity-related comorbidities and an increase in life expectancy after surgical treatment. Unfortunately, serious complications can appear after surgery, and the careful preoperative assessment of patients is necessary to estimate the indications and contraindications of bariatric surgery. Recent studies report the lower complication and mortality rates when bariatric procedures are performed in high-volume centers. The purpose of this review is to describe the techniques of the currently used surgical procedures and the clinical effectiveness of bariatric surgery. Additionally, the possible complications and mortality rates after bariatric surgery are discussed.Keywords: obesity, surgery, assessment, clinical effectiveness, complications

    2015-01-01

    Objectives: To evaluate the cognition enhancing effect of the combination of Spirulina and glycyrrhizin in monosodium glutamate (MSG)-induced obese aged rats. Materials and Methods: Obesity was induced in rats by administration of MSG (intraperitoneally, 4 mg/g body weight) for 14 consecutive days from day 1 after birth. Subsequently, the animals were allowed to grow for 18 months with food and water ad libitum. Hypercholesterolemia, hyperglycemia, leptin resistance, were monitored in these animals. Cognitive status was assessed by Barne's maze task and hippocampal acetylcholinesterase (AChE) levels. Further, the animals were treated with Spirulina (Sp) (oral route, 1 g/Kg body weight, for 30 days) alone or glycyrrhizin (Gly) alone (intraperitoneal route, 0.1 mg/Kg, on day 15 and day 21), or their combination (SpGly). Counting of the treatment days was done by considering first day of Sp administration as day 1. After the completion of 30 days of Spirulina treatment or 2 doses of Gly administration or the combination (SpGly) treatment, the animals were left for 3 weeks. They were then were assessed for their biochemical and cognitive changes. Results: The combination of Sp with Gly showed a significant reduction (P < 0.0001) in glucose, cholesterol, leptin levels in the serum with improvement in cognitive functions with concomitant reduction in AChE activity in the hippocampal tissue homogenates (P < 0.0001) of the obese rats. Conclusion: SpGly combination has a potential role in reversing cognitive dysfunctions associated with aging and obesity. PMID:25821309

    Full Text Available Abstract Background The rising burden of obesity in Tonga is alarming. The promotion of healthy behaviours and environments requires immediate urgent action and a multi-sectoral approach. A three-year community based study titled the Ma'alahi Youth Project (MYP conducted in Tonga from 2005-2008 aimed to increase the capacity of the whole community (schools, churches, parents and adolescents to promote healthy eating and regular physical activity and to reduce the prevalence of overweight and obesity amongst youth and their families. This paper reflects on the process evaluation for MYP, against a set of Best Practice Principles for community-based obesity prevention. Methods MYP was managed by the Fiji School of Medicine. A team of five staff in Tonga were committed to planning, implementation and evaluation of a strategic plan, the key planks of which were developed during a two day community workshop. Intervention activities were delivered in villages, churches and schools, on the main island of Tongatapu. Process evaluation data covering the resource utilisation associated with all intervention activities were collected, and analysed by dose, frequency and reach for specific strategies. The action plan included three standard objectives around capacity building, social marketing and evaluation; four nutrition; two physical activity objectives; and one around championing key people as role models. Results While the interventions included a wide mix of activities straddling across all of these objectives and in both school and village settings, there was a major focus on the social marketing and physical activity objectives. The intervention reach, frequency and dose varied widely across all activities, and showed no consistent patterns. Conclusions The adolescent obesity interventions implemented as part of the MYP program comprised a wide range of activities conducted in multiple settings, touched a broad spectrum of the population (wider than the target group, but the dose and frequency of activities were generally insufficient and not sustained. Also the project confirmed that, while the MYP resulted in increased community awareness of healthy behaviours, Tonga is still in its infancy in terms of conducting public health research and lacks research infrastructure and capacity.

    The obesity epidemic is spreading to low-income and middle-income countries as a result of new dietary habits and sedentary ways of life, fuelling chronic diseases and premature mortality. In this report we present an assessment of public health strategies designed to tackle behavioural risk factors for chronic diseases that are closely linked with obesity, including aspects of diet and physical inactivity, in Brazil, China, India, Mexico, Russia, and South Africa. England was included for comparative purposes. Several population-based prevention policies can be expected to generate substantial health gains while entirely or largely paying for themselves through future reductions of health-care expenditures. These strategies include health information and communication strategies that improve population awareness about the benefits of healthy eating and physical activity; fiscal measures that increase the price of unhealthy food content or reduce the cost of healthy foods rich in fibre; and regulatory measures that improve nutritional information or restrict the marketing of unhealthy foods to children. A package of measures for the prevention of chronic diseases would deliver substantial health gains, with a very favourable cost-effectiveness profile. PMID:21074255

    Full Text Available Functional, molecular and genetic neuroimaging has highlighted the existence of brain anomalies and neural vulnerability factors related to obesity and eating disorders such as binge eating or anorexia nervosa. In particular, decreased basal metabolism in the prefrontal cortex and striatum as well as dopaminergic alterations have been described in obese subjects, in parallel with increased activation of reward brain areas in response to palatable food cues. Elevated reward region responsivity may trigger food craving and predict future weight gain. This opens the way to prevention studies using functional and molecular neuroimaging to perform early diagnostics and to phenotype subjects at risk by exploring different neurobehavioral dimensions of the food choices and motivation processes. In the first part of this review, advantages and limitations of neuroimaging techniques, such as functional magnetic resonance imaging (fMRI, positron emission tomography (PET, single photon emission computed tomography (SPECT, pharmacogenetic fMRI and functional near-infrared spectroscopy (fNIRS will be discussed in the context of recent work dealing with eating behavior, with a particular focus on obesity. In the second part of the review, non-invasive strategies to modulate food-related brain processes and functions will be presented. At the leading edge of non-invasive brain-based technologies is real-time fMRI (rtfMRI neurofeedback, which is a powerful tool to better understand the complexity of human brain–behavior relationships. rtfMRI, alone or when combined with other techniques and tools such as EEG and cognitive therapy, could be used to alter neural plasticity and learned behavior to optimize and/or restore healthy cognition and eating behavior. Other promising non-invasive neuromodulation approaches being explored are repetitive transcranial magnetic stimulation (rTMS and transcranial direct-current stimulation (tDCS. Converging evidence points at the value of these non-invasive neuromodulation strategies to study basic mechanisms underlying eating behavior and to treat its disorders. Both of these approaches will be compared in light of recent work in this field, while addressing technical and practical questions. The third part of this review will be dedicated to invasive neuromodulation strategies, such as vagus nerve stimulation (VNS and deep brain stimulation (DBS. In combination with neuroimaging approaches, these techniques are promising experimental tools to unravel the intricate relationships between homeostatic and hedonic brain circuits. Their potential as additional therapeutic tools to combat pharmacorefractory morbid obesity or acute eating disorders will be discussed, in terms of technical challenges, applicability and ethics. In a general discussion, we will put the brain at the core of fundamental research, prevention and therapy in the context of obesity and eating disorders.

    The new German prevention act attempts to deal with the influx of obesity and chronic diseases by educating and informing. It seeks to change individual behaviour and supress lifestyle-related risk factors. In the past, however this behavioural prevention strategy has proved ineffective. A structural prevention strategy, as requested by the WHO, should additionally be put into effect with measures that reach all walks of life, not just the health-conscious people in society. It proposes the following: · At least one hour of daily physical activity or sport at school and kindergarten. · A differential food tax that makes unhealthy foods more expensive and healthy foods cheaper (taxing sugary / fatty foods). · Mandatory quality standards for kindergarten and school meals. · Banning food advertising targeted at children.

    Oxytocin has been suggested as a novel therapeutic against obesity, because it induces weight loss and improves glucose tolerance in diet-induced obese rodents. A recent clinical pilot study confirmed the oxytocin-induced weight-reducing effect in obese nondiabetic subjects. Nevertheless, the mechanisms involved and the impact on the main comorbidity associated with obesity, type 2 diabetes, are unknown. Lean and ob/ob mice (model of obesity, hyperinsulinemia, and diabetes) were treated for 2...

    Obesity-induced changes in lipid metabolism are mechanistically associated with the development of insulin resistance and prediabetes. Recent studies have focused on the extent to which obesity-induced insulin resistance is mediated through oxylipins, derived from enzymatic and nonenzymatic lipid peroxidation. Vitamin E and vitamin C are widely used antioxidant supplements, but conflicting data exist as to whether supplementation with vitamins E and C reduces insulin resistance. The purpose of this work is (1) to test the hypothesis that supplementation with vitamin E and vitamin C prevents the development of insulin resistance and (2) to determine the extent to which antioxidant supplementation modifies obesity-induced changes in hepatic oxylipins. Using obesity-prone Sprague-Dawley rats fed a high-fat, hypercaloric diet, we found that vitamin E and C supplementation did not block the development of insulin resistance, despite increased plasma levels of these antioxidants and decreased hepatic F2-isoprostane (F2-IsoP) concentrations. The obese phenotype was associated with increased hepatic concentrations of cytochrome P450 (CYP450)-dependent linoleic acid and ?-linolenic acid-derived epoxides. Antioxidant supplementation, but not obesity, decreased levels of the lipoxygenase (LOX)-dependent, arachidonic acid-derived products lipoxin A4 (LXA4), 8,15-dihydroxtetraenoate (8,15-DiHETE), and 5,15-DiHETE. Our data demonstrate that antioxidant supplementation and obesity impact hepatic LOX- and CYP450-dependent oxylipin metabolism. PMID:26398714

    Non-fasting triglyceridemia is much closer associated to cardiovascular risk compared to fasting triglyceridemia. We hypothesized that there would be acute differential effects of four common dietary proteins (cod protein, whey isolate, gluten, and casein) on postprandial lipemia in obese non-diabetic subjects. To test the hypothesis we conducted a randomized, acute clinical intervention study with crossover design. We supplemented a fat rich mixed meal with one of four dietary proteins i.e. cod protein, whey protein, gluten or casein. Eleven obese non-diabetic subjects (age: 40-68, body mass index: 30.3-42.0 kg/m(2)) participated and blood samples were drawn in the 8-h postprandial period. Supplementation of a fat rich mixed meal with whey protein caused lower postprandial lipemia (P = .048) compared to supplementation with cod protein and gluten. This was primarily due to lower triglyceride concentration in the chylomicron rich fraction (P = .0293). Thus, we have demonstrated acute differential effects on postprandial metabolism of four dietary proteins supplemented to a fat rich mixed meal in obese non-diabetic subjects. Supplementation with whey protein caused lower postprandial lipemia compared to supplementation with cod and gluten. As postprandial lipemia is closely correlated to cardiovascular disease, long-term dietary supplementation with whey protein may prove beneficial in preventing cardiovascular disease in obese non-diabetic subjects.

  6. Economic instruments for obesity prevention: results of a scoping review and modified delphi survey

    Full Text Available Abstract Background Comprehensive, multi-level approaches are required to address obesity. One important target for intervention is the economic domain. The purpose of this study was to synthesize existing evidence regarding the impact of economic policies targeting obesity and its causal behaviours (diet, physical activity, and to make specific recommendations for the Canadian context. Methods Arksey and O'Malley's (2005 methodological framework for conducting scoping reviews was adopted for this study and this consisted of two phases: 1 a structured literature search and review, and 2 consultation with experts in the research field through a Delphi survey and an in-person expert panel meeting in April 2010. Results Two key findings from the scoping review included 1 consistent evidence that weight outcomes are responsive to food and beverage prices. The debate on the use of food taxes and subsidies to address obesity should now shift to how best to address practical issues in designing such policies; and 2 very few studies have examined the impact of economic instruments to promote physical activity and clear policy recommendations cannot be made at this time. Delphi survey findings emphasised the relatively modest impact any specific economic instrument would have on obesity independently. Based on empirical evidence and expert opinion, three recommendations were supported. First, to create and implement an effective health filter to review new and current agricultural polices to reduce the possibility that such policies have a deleterious impact on population rates of obesity. Second, to implement a caloric sweetened beverage tax. Third, to examine how to implement fruit and vegetable subsidies targeted at children and low income households. Conclusions In terms of economic interventions, shifting from empirical evidence to policy recommendation remains challenging. Overall, the evidence is not sufficiently strong to provide clear policy direction. Additionally, the nature of the experiments needed to provide definitive evidence supporting certain policy directions is likely to be complex and potentially unfeasible. However, these are not reasons to take no action. It is likely that policies need to be implemented in the face of an incomplete evidence base.

    Full Text Available En las últimas décadas la obesidad se ha convertido en un importante problema de salud pública en las sociedades desarrolladas y economías en transición. Los rápidos cambios sociales acontecidos desde mediados del siglo 20 impulsaron importantes transformaciones en los hábitos alimentarios y estilos [...] de vida, con el progresivo abandono de los modelos alimentarios y técnicas culinarias tradicionales, importante disminución de la actividad física y aumento del tiempo de sedentarismo, dando como resultado un desequilibrio en el balance energético. La obesidad es un factor de riesgo asociado para muchas enfermedades crónicas. En los niños además de condicionar su salud como adultos, afecta su salud física, emocional y social durante la niñez. Según algunas estimaciones el coste de la obesidad puede representar hasta el 12% del gasto sanitario en algunos países. Se han desarrollado muchas acciones desde que en torno al año 2000 la OMS alertara sobre el problema. El análisis de los factores implicados en el origen del problema han llevado a reconocer la importancia de crear ambientes favorables para que las opciones alimentarias y de actividad física más saludables sean las más fáciles y asequibles en las actividades y entornos cotidianos más habituales, como colegios, medio laboral, entorno comunitario. Desde hace tiempo se dispone de evidencia de que las intervenciones más efectivas para la prevención de la obesidad infantil deben contemplar múltiples estrategias y prolongarse en el tiempo. Hoy además reconocemos la importancia de poner en marcha políticas que favorezcan entornos amables que estimulen la práctica de actividad física, favorezcan decisiones que permitan configurar hábitos alimentarios más saludables. Abstract in english In recent decades, obesity has become a major public health problem in developed societies and economies in transition. Rapid social changes that have occurred since the mid 20th century prompted major changes in eating habits and lifestyles, with the gradual abandonment of traditional dietary patte [...] rns and culinary techniques, significant decrease in physical activity and increased sedentary time, giving as result in an imbalance in the energy balance. Obesity is a risk factor for many chronic diseases. There is evidence that childhood obesity influences adult health condition. Additionally, obesity in children affects their physical, emotional and social wellbeing. According to some estimates the cost of obesity may represent up to 12% of health cost in some countries. Many actions have been developed since around the year 2000 WHO alerted about the problem. The analysis of the factors involved in the origin of the problem have led to recognize the importance of creating supportive environments for healthier food choices and physical activity to be the easiest and accessible options in common everyday environments, such as schools, workplace or community environment. Evidence is long available that the most effective interventions to prevent childhood obesity should consider multiple strategies and last longer. Today it is also recognized the importance of implementing policies that encourage supportive friendly environments for physical activity and help decisions to opt for healthy eating habits.

    Obesity is an important risk factor for cardiovascular diseases. Change of life style plays very important role for the management of overweight and obesity and related cardiovascular risk factors. Patients need to acquire and adopt these changes. The aim of this study was to screen practices for overweight and obese patients, to decrease their cardiovascular risk and prevent development of cardiovascular diseases. 2489 overweight patients were screened from 29 general practices since April of 2001. The authors surveyed their characteristics of life style: eating and exercise habits, body mass index, waist line, resting blood pressure, heart rate and plasma glucose, total cholesterin, triglyceride, HDL after a 12-hour fasting. A team, which consisted of an internist, a dietician and a physical instructor dealt with the patients. After ruling out secondary obesity the team tailored an individual life-style which focused on dietary interventions (low calorie diet) and increased physical activity. 12 months later the body mass index decreased significantly by 0.56 kg/m 2 on average and further 0.088 kg/m 2 by the end of the second year, the waist line first did not change significantly then decreased 0.04 cm. The rest systolic blood pressure cut down significantly on average 5.9 Hg mm in the first year, and more 0.11 Hg mm by the end of second year. The metabolic parameters also decreased significantly: total cholesterin 0.23 mmol/l in the first year, 0.07 mmol/l in the second year, triglyceride: 0.18 mmol/l; 0.08 mmol/l, blood glucose: 0.15 mmol/l; 0.19 mmol/l. The level of HDL did not change. It is very important for management of overweight and obesity that patients adopt changes of life style. The authors' results show that these patients must be followed very strictly. PMID:17344121

    Obesity is a chronic metabolic disorder that is associated with numerous diseases including hyperlipidemia, diabetes mellitus, hypertension, atherosclerosis, cardiovascular disease, and cancer. Cinnamic acid is a phytochemical compound having many biological effects and could be considered for the management of obesity. This study is aimed to assess the possible anti-obesity and cardioprotective properties of cinnamic acid (CA) in high fat diet-fed rats (HFD). Male Wistar rats were divided into 4 groups. They received normal diet, HFD diet, HFD supplemented with fluvastatin (2 mg/kg/day) or cinnamic acid (30 mg/kg/day) for 7 weeks. The results showed an increase in body weight of HFD rats by ~27 % as compared to control group. Moreover, serum lipase activity underwent a significant rise by 103 % which led to an increase in the levels of total cholesterol (T-Ch), triglycerides (TG), LDL-cholesterol in serum of untreated HFD-fed rats. Furthermore, the concentration of leptin and angiotensin-converting enzyme (ACE) activity exhibited remarkable increases in serum of HFD-fed rats as compared to controls. Whereas, the administration of CA to HFD-fed rats improved the body weight gain and serum lipid profile and reverted back near to normal the activities of lipase and ACE. In addition, the echocardiography evidenced that CA is able to protect the aorta and aortic arch and avoided vasoconstriction by increasing their diameters and improved liver steatosis and kidney indices of toxicity. Overall, these results suggest that cinnamic acid exerts anti-obesity and antihypertensive effects through inhibition of lipid digestive enzymes and ACE. PMID:26139902

    Type 2 diabetes is extremely common in South Asians, e.g. in men from Pakistani and Indian populations it is about three times as likely as in the general population in England, despite similarities in body mass index. Lifestyle interventions reduce the incidence of diabetes. Trials in Europe and North America have not, however, reported on the impact on South Asian populations separately or provided the details of their cross-cultural adaptation processes. Prevention of diabetes and obesity in South Asians (PODOSA) is a randomized, controlled trial in Scotland of an adapted, lifestyle intervention aimed at reducing weight and increasing physical activity to reduce type 2 diabetes in Indians and Pakistanis. The trial was adapted from the Finnish Diabetes Prevention Study. We describe, reflect on and discuss the following key issues: The core adaptations to the trial design, particularly the delivery of the intervention in homes by dietitians rather than in clinics. The use of both a multilingual panel and professional translators to help translate and/or develop materials. The processes and challenges of phonetic translation. How intervention resources were adapted, modified, newly developed and translated into Urdu and Gurmukhi (written Punjabi). The insights gained in PODOSA (including time pressures on investigators, imperfections in the adaptation process, the power of verbal rather than written information, the utilization of English and the mother-tongue languages simultaneously by participants and the costs) might help the research community, given the challenge of health promotion in multi-ethnic, urban societies.

    The prevalence of obesity increases and is associated with increases in co-morbidities e.g. type 2 diabetes, hyperlipidemia, hypertension, obstructive sleep apnea, heart disease, stroke, asthma, several forms of cancer, depression, and may result in reduction of expected remaining lifespan. We have reviewed the adverse effects on the cardiovascular system of anti-obesity drugs now retracted from the market as well as the cardiovascular profile of current drugs and potential pathways which are considered for treatment of obesity. Fenfluramine, and sibutramine were withdrawn due to increased cardiovascular risk, while an inverse agonist at cannabinoid type 1 (CB1) receptors, rimonobant was withdrawn due to serious psychiatric problems. At present there are only few treatments available including orlistat and, phentermine alone or in combination with topiramate and lorcaserin, although cardiovascular side effects need to be clarified regarding phentermine and lorcaserin. Drugs approved for type 2 diabetes including glucagon like peptide (GLP-1) analogues and metformin also cause moderate weight losses and have a favourable cardiovascular profile, while the anti-obesity potential of nebivolol remains unexplored. Pathways with anti-obesity potential include sirtuin activation, blockade of transient receptor potential (TRPV1) channels, acetyl-CoA carboxylase 1 and 2 inhibitors, uncoupling protein activators, bile acids, crotonins, CB1 antagonists, but the cardiovascular profile remains to be investigated. For type 2 diabetes, new drug classes with possible advantageous cardiovascular profiles, e.g. GLP-1 analogues and sodium-glucose co-transport type 2 inhibitors, are associated with weight loss and are currently being evaluated as anti-obesity drugs.

We have reviewed the adverse effects on the cardiovascular system of anti-obesity drugs now retracted from the market as well as the cardiovascular profile of current drugs and potential pathways which are considered for treatment of obesity. Fenfluramine, and sibutramine were withdrawn due to increased cardiovascular risk, while an inverse agonist at cannabinoid type 1 (CB1) receptors, rimonobant was withdrawn due to serious psychiatric problems. At present there are only few treatments available including orlistat and, phentermine alone or in combination with topiramate and lorcaserin, although cardiovascular side effects need to be clarified regarding phentermine and lorcaserin. Drugs approved for type 2 diabetes including glucagon like peptide (GLP-1) analogues and metformin also cause moderate weight losses and have a favourable cardiovascular profile, while the anti-obesity potential of nebivolol remains unexplored. Pathways with anti-obesity potential include sirtuin activation, blockade of transient receptor potential (TRPV1) channels, acetyl-CoA carboxylase 1 and 2 inhibitors, uncoupling protein activators, bile acids, crotonins, CB1 antagonists, but the cardiovascular profile remains to be investigated. For type 2 diabetes, new drug classes with possible advantageous cardiovascular profiles, e.g. GLP-1 analogues and sodium-glucose co-transport type 2 inhibitors, are associated with weight loss and are currently being evaluated as anti-obesity drugs.

    Neighborhood environment is consistently associated with obesity; changes to modifiable aspects of the neighborhood environment may curb the growth of obesity in the US and other developed nations. However, currently the majority of studies are cross-sectional and thus not appropriate for evaluating causality. The goal of this study was to evaluate the effect of a neighborhood-changing intervention on changes in obesity among older women. Over the past 30 years the Portland, Oregon metropolitan region has made significant investments in plans, regulatory structures, and public facilities to reduce sprawl and increase compact growth centers, transit-oriented development approaches, and green space. We used geocoded residential addresses to link data on land-use mix, public transit access, street connectivity, and access to green space from four time points between 1986 and 2004, with longitudinal data on body mass index (BMI) from a cohort of 2003 community-dwelling women aged 66 years and older. Height and weight were measured at clinic visits. Women self-reported demographics, health habits, and chronic conditions, and self-rated their health. Neighborhood socioeconomic status was assessed from census data. Neighborhood walkability and access to green space improved over the 18-year study period. On average there was a non-significant mean weight loss in the cohort between baseline (mean age 72.6 years) and the study's end (mean age 85.0 years). We observed no association between neighborhood built environment or change in built environment and BMI. Greater neighborhood socioeconomic status at baseline was independently associated with a healthier BMI at baseline, and protected against an age-related decline in BMI over time. BMI decreases with age reflect increased frailty, especially among older adults with complex morbidities. Future research should consider the influence of the neighborhood environment on additional relevant health outcomes and should include measures of the social environment in conjunction with built environment measures.

    Shehzad, Adeeb; Khan, Salman; Sup Lee, Young

    2012-02-01

    Obesity is characterized as an increased BMI, which is associated with the increased risk of several common cancers, including colorectal, breast, endometrial, renal, esophageal, gallbladder, melanoma, multiple myeloma, leukemia, lymphoma and prostate cancer. The increased risk of obesity-related cancers could be mediated by insulin resistance, adipokines, obesity-related inflammatory cytokines, sex hormones, transcription factors and oxidative stress, which disrupt the balance between cell proliferation and apoptosis. The yellowish compound, curcumin (diferuloylmethane), is known to possess multifaceted pharmacological effects. The molecular mechanisms linking obesity to cancer risk, and how curcumin mediates anticancer and obesity activities, have not yet been publicized. Curcumin modulates multiple molecular targets and reverses insulin resistance as well as other symptoms that are associated with obesity-related cancers. In this study, we show that ample evidence exists to support recommendations that curcumin mediates multiple molecular pathways, and is considered to be of therapeutic value in the treatment and prevention of obesity-related cancers.

    2015-01-01

    Obesity, which results from an imbalance between energy intake and energy expenditure, has become a major health risk factor worldwide, causing numerous and various diseases such as diabetes, hypertension, and cardiovascular diseases. Fucoxanthin, a specific carotenoid in brown algae, has garnered much attention for its anti-obesity and anti-diabetic effects attributable to a unique mechanism. Fucoxanthin induces uncoupling protein 1 (UCP1) expression in white adipose tissue (WAT). That inner membrane mitochondrial protein, UCP1, can dissipate energy through oxidation of fatty acids and heat production. Furthermore, fucoxanthin improves insulin resistance and ameliorates blood glucose levels through down-regulation of adipocytokines related to insulin resistance in WAT and up-regulation of glucose transporter 4 (GLUT4) in skeletal muscle. Algae fucoxanthin is a beneficial compound for the prevention of the metabolic syndrome. PMID:25748372

    It is the position of the Academy of Nutrition and Dietetics that prevention and treatment of pediatric overweight and obesity require systems-level approaches that include the skills of registered dietitians, as well as consistent and integrated messages and environmental support across all sectors of society to achieve sustained dietary and physical-activity behavior change. This position paper provides guidance and recommendations for levels of intervention targeting overweight and obesity prevention and treatment from preschool age through adolescence. Methods included a review of the literature from 2009 to April 2012, including the Academy's 2009 evidence analysis school-based reviews. Multicomponent interventions show the greatest impact for primary prevention; thus, early childhood and school-based interventions should integrate behavioral and environmental approaches that focus on dietary intake and physical activity using a systems-level approach targeting the multilevel structure of the socioecological model as well as interactions and relationships between levels. Secondary prevention and tertiary prevention/treatment should emphasize sustained family-based, developmentally appropriate approaches that include nutrition education, dietary counseling, parenting skills, behavioral strategies, and physical-activity promotion. For obese youth with concomitant serious comorbidities, structured dietary approaches and pharmacologic agents should be considered, and weight-loss surgery can be considered for severely obese adolescents. Policy and environmental interventions are recommended as feasible and sustainable ways to support healthful lifestyles for children and families. The Academy supports commitment of resources for interventions, policies, and research that promote healthful eating and physical-activity behaviors to ensure that all youth have the opportunity to achieve and maintain a weight that is optimal for health.

  8. Telmisartan prevents weight gain and obesity through activation of peroxisome proliferator-activated receptor-delta-dependent pathways

    He, Hongbo; Yang, Dachun

    2010-01-01

    Telmisartan shows antihypertensive and several pleiotropic effects that interact with metabolic pathways. In the present study we tested the hypothesis that telmisartan prevents adipogenesis in vitro and weight gain in vivo through activation of peroxisome proliferator-activated receptor (PPAR)-delta-dependent pathways in several tissues. In vitro, telmisartan significantly upregulated PPAR-delta expression in 3T3-L1 preadipocytes in a time- and dose-dependent manner. Other than enhancing PPAR-delta expression by 68.2+/-17.3% and PPAR-delta activity by 102.0+/-9.0%, telmisartan also upregulated PPAR-gamma expression, whereas neither candesartan nor losartan affected PPAR-delta expression. In vivo, long-term administration of telmisartan significantly reduced visceral fat and prevented high-fat diet-induced obesity in wild-type mice and hypertensive rats but not in PPAR-delta knockout mice. Administration of telmisartan did not influence food intake in mice. Telmisartan influenced several lipolytic and energy uncoupling related proteins (UCPs) and enhanced phosphorylated protein kinase A and hormone sensitive lipase but reduced perilipin expression and finally inhibited adipogenesis in 3T3-L1 preadipocytes. Telmisartan-associated reduction of adipogenesis in preadipocytes was significantly blocked after PPAR-delta gene knockout. Chronic telmisartan treatment upregulated the expressions of protein kinase A, hormone-sensitive lipase, and uncoupling protein 1 but reduced perilipin expression in adipose tissue and increased uncoupling protein 2 and 3 expression in skeletal muscle in wild-type mice but not in PPAR-delta knockout mice. We conclude that telmisartan prevents adipogenesis and weight gain through activation of PPAR-delta-dependent lipolytic pathways and energy uncoupling in several tissues.

    Parental participation is a key factor in the prevention and management of childhood obesity, thus parental recognition of weight problems is essential. We estimated parental perceptions and their determinants in the Emirati population. We invited 1541 students (grade 1–12; 50% boys) and their parents, but only 1440 (6–19 years) and their parents consented. Of these, 945 Emirati nationals provided data for analysis. Anthropometric and demographic variables were measured by standard methods. CDC BMI percentile charts for age and sex were used to classify children’s weight. Parental perception of their children’s weight status (underweight, normal, and overweight/obese) was recorded. Logistic regression analyses were used to identify independent predictors of parental perceptions of children’s weight status. Of all parents, 33.8% misclassified their children’s’ weight status; underestimating (27.4%) or overestimating (6.3%). Misclassification was highest among parents of overweight/obese children (63.5%) and underweight (55.1%) children. More importantly, parental perceptions of their children being overweight or obese, among truly overweight/obese children, i.e. correct identification of an overweight/obese child as such, were associated with the true child’s BMI percentile (CDC) with an OR of 1.313 (95% CI: 1.209–1.425; pchild’s sex. We conclude that the majority of parents of overweight/obese children either overestimated or, more commonly, underestimated children’s weight status. Predictors of accurate parental perception, in this population, include the true children’s BMI, but not age, household income, and sex. Thus, parents having an incorrect perception of their child’s weight status may ignore otherwise appropriate health messages. PMID:23555833

    Background Mobile technologies have wide-scale reach and disseminability, but no known studies have examined mobile technologies as a stand-alone tool to improve obesity-related behaviors of at-risk youth. Purpose To test a 12-week mobile technology intervention for use and estimate effect sizes for a fully powered trial. Methods Fifty-one low-income, racial/ethnic minority girls aged 9–14 years were randomized to a mobile technology (n=26) or control (n=25) condition. Both conditions lasted 12 weeks and targeted fruits/vegetables (FV; weeks 1–4), sugar-sweetened beverages (SSB; weeks 5–8), and 2 screen time (weeks 9–12). The mobile intervention prompted real-time goal setting and self-monitoring and provided tips, feedback, and positive reinforcement related to the target behaviors. Controls received the same content in a written manual but no prompting. Outcomes included device utilization and effect sizes estimates of FV, SSB, screen time, and BMI. Data were collected and analyzed in 2011–2012. Results Mobile technology girls used the program on 63% of days and exhibited trends toward increased FVs (+0.88, p=0.08) and decreased SSBs (?0.33, p=0.09). The adjusted difference between groups of 1.0 servings of FV (p=0.13) and 0.35 servings of SSB (p=0.25) indicated small to moderate effects of the intervention (Cohen’s d=0.44 and ?0.34, respectively). No differences were observed for screen time or BMI. Conclusions A stand-alone mobile app may produce small to moderate effects for FV and SSB. Given the extensive reach of mobile devices, this pilot study demonstrates the need for larger-scale testing of similar programs to address obesity-related behaviors in high-risk youth.

    2007-05-01

    Full Text Available Abstract Background Studies have shown that a proportion of children as young as two years are already overweight. This indicates that obesity prevention programs that commence as early as possible and are family-focused are needed. This Healthy Beginnings Trial aims to determine the efficacy of a community-based randomized controlled trial (RCT of a home visiting intervention in preventing the early onset of childhood overweight and obesity. The intervention will be conducted over the first two years of life to increase healthy feeding behaviours and physical activity, decrease physical inactivity, enhance parent-child interaction, and hence reduce overweight and obesity among children at 2 and 5 years of age in the most socially and economically disadvantaged areas of Sydney, Australia. Methods/design This RCT will be conducted with a consecutive sample of 782 first time mothers with their newborn children. Pregnant women who are expecting their first child, and who are between weeks 24 and 34 of their pregnancy, will be invited to participate in the trial at the antenatal clinic. Informed consent will be obtained and participants will then be randomly allocated to the intervention or the control group. The allocation will be concealed by sequentially numbered, sealed opaque envelopes containing a computer generated random number. The intervention comprises eight home visits from a specially trained community nurse over two years and pro-active telephone support between the visits. Main outcomes include a duration of breastfeeding measured at 6 and 12 months, b introduction of solids measured at 4 and 6 months, c nutrition, physical activity and television viewing measured at 24 months, and d overweight/obesity status at age 2 and 5 years. Discussion The results of this trial will ascertain whether the home based early intervention is effective in preventing the early onset of childhood overweight and obesity. If proved to be effective, it will result in a series of recommendations for policy and practical methods for promoting healthy feeding and physical activity of children in the first two years of life with particular application to families who are socially and economically disadvantaged.

    2014-12-01

    This paper presents a system dynamics policy model of nutritional food market transformation, tracing over-time interactions between the nutritional quality of supply, consumer food choice, population health, and governmental policy. Applied to the Canadian context and with body mass index as the primary outcome, we examine policy portfolios for obesity prevention, including (1) industry self-regulation efforts, (2) health- and nutrition-sensitive governmental policy, and (3) efforts to foster health- and nutrition-sensitive innovation. This work provides novel theoretical and practical insights on drivers of nutritional market transformations, highlighting the importance of integrative policy portfolios to simultaneously shift food demand and supply for successful and self-sustaining nutrition and health sensitivity. We discuss model extensions for deeper and more comprehensive linkages of nutritional food market transformation with supply, demand, and policy in agrifood and health/health care. These aim toward system design and policy that can proactively, and with greater impact, scale, and resilience, address single as well as double malnutrition in varying country settings.

    2014-05-01

    Since the 1970s, the proportion of overweight and obese people in the United States has grown at an alarming rate. An awareness of the consequences of obesity on the health and well-being of individuals is evident in the plethora of strategic plans at the local and national levels, most of which have largely fallen short of their goals. If interventions continue to be unsuccessful, it is estimated that approximately three of four Americans will be overweight or obese by 2020. Prevention of excess weight gain can be accomplished with relatively small changes in lifestyle behaviours to control body weight. Small sustainable changes are perhaps better than efforts to achieve larger changes that cannot be sustained. Legumes can be a valuable food by which the needs of the undernourished or under-served populations could be met. They can be incorporated into meat products, such as sausages and burgers, to lower the energy density of these foods while providing important nutrients. Replacing energy-dense foods with legumes has been shown to have beneficial effects on the prevention and management of obesity and related disorders, such as cardiovascular disease, diabetes and the metabolic syndrome. This review explores the nutritional value and obesity-related health benefits of legume consumption while focusing on pulses. PMID:24433379

    2013-01-01

    Full Text Available It is estimated that about half of the population in developed countries are either overweight or obese. In some developing nations obesity rates have increased to surpass those seen in Western countries. This rate increase in obesity has many implications as obesity has been associated with numerous negative health effects including increased risks of hypertension, diabetes, cardiovascular disease, stroke, liver disease, apnea, and some cancer types. Obesity is now considered to be one of the major public health concerns facing the society. Cholangiocarcinomas (bile duct cancers are malignant tumors arising from cholangiocytes inside or outside of the liver. Although cholangiocarcinomas are relatively rare, they are highly lethal. The low survival rate associated with cholangiocarcinoma is due to the advanced stage of the disease at the time of diagnosis. Prevention is therefore especially important in this cancer type.

    It is estimated that about half of the population in developed countries are either overweight or obese. In some developing nations obesity rates have increased to surpass those seen in Western countries. This rate increase in obesity has many implications as obesity has been associated with numerous negative health effects including increased risks of hypertension, diabetes, cardiovascular disease, stroke, liver disease, apnea, and some cancer types. Obesity is now considered to be one of the major public health concerns facing the society. Cholangiocarcinomas (bile duct cancers) are malignant tumors arising from cholangiocytes inside or outside of the liver. Although cholangiocarcinomas are relatively rare, they are highly lethal. The low survival rate associated with cholangiocarcinoma is due to the advanced stage of the disease at the time of diagnosis. Prevention is therefore especially important in this cancer type. Some data suggest that the incidence of cholangiocarcinoma in the western world is on the rise. Increasing rate of obesity may be one of the factors responsible for this increase.

    Obesity is a risk factor for stroke, but the determinants of increased stroke risk in obesity are unknown. We have previously reported that obese Zucker rats (OZRs) have a worse stroke outcome and display evidence of remodeling of the middle cerebral artery (MCA), in parallel with hypertension, compared with lean controls. This study tested the hypothesis that hypertension is an essential determinant of cerebral vascular remodeling and increased stroke damage in OZRs. Blood pressure was measu...

    Our evaluation study identifies facilitators and barriers to participation among families participating in the treatment arm of Stanford ECHALE. This culturally tailored obesity prevention trial consisted of a combined intervention with two main treatment components: 1) a folkloric dance program; and 2) a screen time reduction curriculum designed for 7-11 year old Latinas and their families. We conducted 83 interviews (40 parents and 43 girls) in participant homes after 6 months of enrollment in the ECHALE trial. The Spradley ethnographic method and NVivo 8.0 were used to code and analyze narrative data. Three domains emerged for understanding participation: 1) family cohesiveness; 2) perceived gains; and 3) culturally relevant program structure. Two domains emerged for non-participation: program requirements and perceived discomforts. Non-parametric, Spearman's rank correlation coefficients were calculated to assess the relationships with participant attendance data. Sustained participation was most strongly influenced by the domain perceived gains when parents reported better self-esteem, confidence, improved attitude, improved grades, etc. (Spearman r = .45, P = .003). Alternatively, under the domain, perceived discomforts, with subthemes such as child bullying, participation in the combined intervention was inversely associated with attendance (Spearman r = -.38, P = .02). Family-centered, school-based, community obesity prevention programs that focus on tangible short-term gains for girls may generate greater participation rates, enhance social capital, and promote community empowerment. These factors can be emphasized in future obesity prevention program design and implementation. PMID:24392608

    Full Text Available We applied the Transtheoretical Model (TTM to develop the Family Stage of Change (FSOC screening tool. Our goal was to provide practitioners an instrument that measures families’ readiness to change obesity preventing behaviors, in order to optimize family-focused obesity-prevention intervention strategies. We evaluated instrument validity by comparing responses on the FSOC to related items on a validated family behavioral and environmental assessment (Family Nutrition and Physical Activity Assessment; FNPA shown to predict child BMI. Study participants included parents and caregivers (N = 146 of children ages 2-14 years recruited through preschool, elementary, and middle school listservs. Descriptive analyses were conducted on the demographic data, and correlations were run to examine associations between FSOC and FNPA items, domains, and total scores. Strong positive correlations were observed between the individual items (0.44 to 0.75, p < 0.001, domain scores (0.57 to 0.8, p < 0.001, and mean total FSOC and FNPA scores (0.78, p < 0.001 suggesting the FSOC is measuring family level behaviors. Test-retest reliability was evaluated on a subsample of participants (n = 57, and item by item correlations ranged from 0.75 to 1.0, p < 0.001. Our findings suggest the FSOC is a valid and reliable instrument and has the potential to meet an identified need related to family-directed, obesity prevention efforts.

  11. SU-C-18C-04: Evaluation of Effective Dose During Ureteroscopy for Obese and Non-Obese Patients

    International Nuclear Information System (INIS)

    Purpose: Ureteroscopy involves fluoroscopy which potentially results in considerable amount of radiation dose to the patient. Purpose of this study was two-fold: (a) to develop the effective dose computational model for obese and non-obese patients undergoing left and right ureteroscopy, and (b) to evaluate the utility of a commercial Monte Carlo software for dose assessment in ureteroscopy. Methods: Organ dose measurements were performed on an adult male anthropomorphic phantom, representing the non-obese patients, with 20 high-sensitivity MOSFET detectors and two 0.18cc ionization chambers placed in selected organs. Fat-equivalent paddings were placed around the abdominal region to simulate for obese patients. Effective dose (ED) was calculated using ICRP 103 tissue weighting factors and normalized to the effective dose rate in miliSivert per second (mSv/s). In addition, a commercial Monte Carlo (MC) dose estimation program was used to estimate ED for the non-obese model, with table attenuation correction applied to simulate clinical procedure. Results: For the equipment and protocols involved in this study, the MOSFETderived ED rates for the obese patient model (‘Left’: 0.0092±0.0004 mSv/s; ‘Right’: 0.0086±0.0004 mSv/s) was found to be more than twice as much as that to the non-obese patient model (‘Left’: 0.0041±0.0003 mSv/s; ‘Right’: 0.0036±0.0007 mSv/s). The MC-derived ED rates for the non-obese patient model (‘Left’: 0.0041 mSv/s; ‘Right’: 0.0036 mSv/s; with statistical uncertainty of 1%) showed a good agreement with the MOSFET method. Conclusion: The significant difference in ED rate between the obese and non-obese patient models shows the limitation of directly applying commercial softwares for obese patients and leading to considerable underestimation of ED. Although commercial softwares offer a convenient means of dose estimation, but the utility may be limited to standard-man geometry as the software does not account for table attenuation, obese patient geometry, and differences between the anthropomorphic phantom and MC mathematical phantom

    Full Text Available Abstract Background Previous studies of public perceptions of obesity interventions have been quantitative and based on general population surveys. This study aims to explore the opinions and attitudes of obese individuals towards population and individual interventions for obesity in Australia. Methods Qualitative methods using in-depth semi-structured telephone interviews with a community sample of obese adults (Body Mass Index ?30. Theoretical, purposive and strategic recruitment techniques were used to ensure a broad sample of obese individuals with different types of experiences with their obesity. Participants were asked about their attitudes towards three population based interventions (regulation, media campaigns, and public health initiatives and three individual interventions (tailored fitness programs, commercial dieting, and gastric banding surgery, and the effectiveness of these interventions. Results One hundred and forty two individuals (19-75 years were interviewed. Participants strongly supported non-commercial interventions that were focused on encouraging individuals to make healthy lifestyle changes (regulation, physical activity programs, and public health initiatives. There was less support for interventions perceived to be invasive or high risk (gastric band surgery, stigmatising (media campaigns, or commercially motivated and promoting weight loss techniques (commercial diets and gastric banding surgery. Conclusion Obese adults support non-commercial, non-stigmatising interventions which are designed to improve lifestyles, rather than promote weight loss.

    2013-07-15

    The study was carried out to investigate the anti-obesity effects of Aegle marmelos leaves extracts and its phytochemical constituents in vitro and in vivo. The dichloromethane (DCM), ethyl acetate (EtOAc) and n-butanol extracts of A. marmelos leaves were studied for their lipolytic effect. Lipolysis was measured by determining the amount of glycerol released at 12 h and 24 h at 50 ?g/ml and 100 ?g/ml concentrations. Phytochemical investigation of the most active DCM extract yielded 14 compounds. The isolated compounds were evaluated for their lipolytic effects at 50 ?M and 100 ?M. The most active compounds, umbelliferone and esculetin were further screened for their antiobesity effects in vivo in the high fat diet (HFD) induced obese rat model. Umbelliferone and esculetin reduced body weight, total triglyceride (TG), total cholesterol (TC) and glucose level in their respective HFD groups. A. marmelos DCM extract and compounds isolated from it have the potential of counteracting the obesity by lipolysis in adipocytes. PMID:23632084

  17. Evaluation of the childhood obesity prevention program Kids - 'Go for your life'

    2010-05-01

    Full Text Available Abstract Background Kids - 'Go for your life' (K-GFYL is an award-based health promotion program being implemented across Victoria, Australia. The program aims to reduce the risk of childhood obesity by improving the socio-cultural, policy and physical environments in children's care and educational settings. Membership of the K-GFYL program is open to all primary and pre-schools and early childhood services across the State. Once in the program, member schools and services are centrally supported to undertake the health promotion (intervention activities. Once the K-GFYL program 'criteria' are reached the school/service is assessed and 'awarded'. This paper describes the design of the evaluation of the statewide K-GFYL intervention program. Methods/Design The evaluation is mixed method and cross sectional and aims to: 1 Determine if K-GFYL award status is associated with more health promoting environments in schools/services compared to those who are members only; 2 Determine if children attending K-GFYL award schools/services have higher levels of healthy eating and physical activity-related behaviors compared to those who are members only; 3 Examine the barriers to implementing and achieving the K-GFYL award; and 4 Determine the economic cost of implementing K-GFYL in primary schools Parent surveys will capture information about the home environment and child dietary and physical activity-related behaviors. Environmental questionnaires in early childhood settings and schools will capture information on the physical activity and nutrition environment and current health promotion activities. Lunchbox surveys and a set of open-ended questions for kindergarten parents will provide additional data. Resource use associated with the intervention activities will be collected from primary schools for cost analysis. Discussion The K-GFYL award program is a community-wide intervention that requires a comprehensive, multi-level evaluation. The evaluation design is constrained by the lack of a non-K-GFYL control group, short time frames and delayed funding of this large scale evaluation across all intervention settings. However, despite this, the evaluation will generate valuable evidence about the utility of a community-wide environmental approach to preventing childhood obesity which will inform future public health policies and health promotion programs internationally.

    2008-12-01

    Full Text Available Abstract Background The home and neighborhood environments may be important in obesity prevention by virtue of food availability, food preparation, cues and opportunities for physical activity, and family support. To date, little research has examined how home and neighborhood environments in rural communities may support or hinder healthy eating and physical activity. This paper reports characteristics of rural homes and neighborhoods related to physical activity environments, availability of healthy foods, and family support for physical activity and maintaining an ideal body weight. Methods In-depth interviews were conducted with 60 African American and White adults over 50 years of age in two rural counties in Southwest Georgia. Interviews were transcribed verbatim and coded independently by two members of the research team using standard methods of qualitative analysis. Themes were then identified and data matrices were used to identify patterns by gender or race. Results Neighborhood features that supported physical activity were plenty of land, minimal traffic and living in a safe and friendly neighborhood. The major barrier was lack of recreational facilities. The majority of participants were not physically active with their family members due to schedule conflicts and lack of time. Family member-initiated efforts to encourage physical activity met with mixed results, with refusals, procrastination, and increased activity all reported. Participants generally reported it was easy to get healthy foods, although cost barriers and the need to drive to a larger town for a supermarket with good variety were noted as obstacles. Family conversations about weight had occurred for about half of the participants, with reactions ranging from agreement about the need to lose weight to frustration. Conclusion This study suggests that successful environmental change strategies to promote physical activity and healthy eating in rural neighborhoods may differ from those used in urban neighborhoods. The findings also provide insight into the complexities of family support for physical activity and maintaining a healthy weight. Addressing socio-ecologic factors has the potential to increase healthy behaviors and decrease the prevalence of obesity among rural residents.

  19. Effects of Aronia melanocarpa polyphenols on oxidative metabolism and apoptosis of neutrophils from obese and non-obese individuals

    Full Text Available Reactive oxygen species are postulated to be involved in systemic inflammation and oxidative stress in patients with obesity. Activated polymorphonuclear neutrophils (PMNs generate extremely high amounts of reactive oxygen species, but these are normally targeted at pathogens inside intracellular phagosomes. The same beneficial antimicrobial functions, if not controlled, contribute to the tissue damaging effects of inflammatory reactions. The evidence from conventional epidemiology strongly implies fruits and vegetables in protection against oxidative stress. In our study, the in vitro effects of Aronia melanocarpa juice on oxidative metabolism and apoptosis of neutrophils from obese and non-obese individuals has been investigated. We tested 15 obese patients (aged 45 ±9 years, women, BMI = 34 ±4.9 kg/m2. Nine healthy subjects (BMI = 22.2 ±1.6 kg/m2 were enrolled as controls. Neutrophils were isolated and oxidant production, in response to phorbol 12-myristate 13-acetate, was characterized by using luminol dependent chemiluminescence (CL and flow cytometric dichlorofluorescin oxidation assay. Caspase-3 activity, a marker of apoptosis execution, in human neutrophils, measured by a cleavage of the fluorogenic substrate Ac-DEVD-AMC. Additional experiments to assess the direct toxic effect of the aronia polyphenols were also carried out. Neutrophils from obese individuals had a significantly higher H2O2 production and CL response compared to controls (p < 0.05. The oxidative metabolism of PMNs was decreased by aronia juice treatment in both of groups, obese and non-obese individuals. The caspase-3 activity depended on the time of aronia juice treatment and was markedly increased in phorbol-treated cells incubated with polyphenols for 24 hours. This natural product exert beneficial effects in cells and may, therefore, be useful in the treatment of obesity disorders.

    2009-11-01

    Full Text Available Data accumulated over recent years have significantly advanced our understanding of growth factors, cytokines, and hormones in breast milk. Here we deal with leptin, adiponectin, IGF-I, ghrelin, and the more recently discovered hormones, obestatin, and resistin, which are present in breast milk and involved in food intake regulation and energy balance. Little is known about these compounds in infant milk formulas. Nutrition in infancy has been implicated in the long-term tendency to obesity, and a longer duration of breastfeeding appears to protect against its development. Diet-related differences in serum leptin and ghrelin values in infancy might explain anthropometric differences and differences in dietary habits between breast-fed and formula-fed infants also later in life. However, there are still gaps in our understanding of how hormones present in breast milk affect children. Here we examine the data related to hormones contained in mother's milk and their potential protective effect on subsequent obesity.

Diet-related differences in serum leptin and ghrelin values in infancy might explain anthropometric differences and differences in dietary habits between breast-fed and formula-fed infants also later in life. However, there are still gaps in our understanding of how hormones present in breast milk affect children. Here we examine the data related to hormones contained in mother's milk and their potential protective effect on subsequent obesity.

  14. Obesity prevention and personal responsibility: the case of front-of-pack food labelling in Australia

    2010-11-01

    Full Text Available Abstract Background In Australia, the food industry and public health groups are locked in serious struggle for regulatory influence over the terms of front-of-pack food labelling. Clear, unambiguous labelling of the nutritional content of pre-packaged foods and of standardized food items sold in chain restaurants is consistent with the prevailing philosophy of 'personal responsibility'. An interpretive, front-of-pack labelling scheme has the capacity to encourage healthier patterns of eating, and to be a catalyst for improvements in the nutritional quality of food products through re-formulation. On the other hand, the strength of opposition of the Australian Food and Grocery Council to 'Traffic Light Labelling', and its efforts to promote a non-interpretive, voluntary scheme, invite the interpretation that the food industry is resistant to any reforms that could destabilise current (unhealthy purchasing patterns and the revenues they represent. Discussion This article argues that although policies that aim to educate consumers about the nutritional content of food are welcome, they are only one part of a broader basket of policies that are needed to make progress on obesity prevention and public health nutrition. However, to the extent that food labelling has the capacity to inform and empower consumers to make healthier choices - and to be a catalyst for improving the nutritional quality of commercial recipes - it has an important role to play. Furthermore, given the dietary impact of meals eaten in fast food and franchise restaurants, interpretive labelling requirements should not be restricted to pre-packaged foods. Summary Food industry resistance to an interpretive food labelling scheme is an important test for government, and a case study of how self-interest prompts industry to promote weaker, voluntary schemes that pre-empt and undermine progressive public health regulation.

  15. Service-learning in Higher Education Relevant to the Promotion of Physical Activity, Healthful Eating, and Prevention of Obesity.

    Service-learning is a type of experiential teaching and learning strategy combining classroom instruction and meaningful community service and guided activities for reflection. This educational approach has been used frequently in higher education settings, including an array of disciplines such as medicine, theology, public health, physical education, nutrition, psychology, anthropology, and sociology. The purpose of the present review paper was to provide guidance on the use of service-learning within higher education, relevant to the preventive medicine and public health topics of healthful eating, physical activity, and obesity prevention. In service-learning, coursework is structured to address community needs, and to benefit students through the real-world application of knowledge. The benefits for students include positive impacts on social skills, empathy, awareness, understanding, and concern regarding community issues, plus greater confidence and skills to work with diverse populations, increased awareness of community resources, improved motivation, and enhanced knowledge. Educational institutions may also benefit through improved "town and gown" relations, as strong ties, partnerships, and mutually beneficial activities take place. The present literature review describes several service-learning applications such as nutrition education for kids, dietary improvement for seniors, foodservice recipe modification on a college campus, an intergenerational physical activity program for nursing home residents, motor skill development in kindergarteners, organized elementary school recess physical activities, health education, and obesity prevention in children. From this review, service-learning appears to have great potential as a flexible component of academic coursework in the areas of preventive medicine and public health. PMID:23112892

    Schools are increasingly recognized as an ideal setting for interventions to tackle childhood obesity. A better understanding of the views of key stakeholders would help to engage schools and inform the feasibility of such interventions in practice. This meta-synthesis of 18 qualitative studies explores the views of parents, school staff, school governors, school nurses and students on the role of the primary school in preventing childhood obesity. Six categories emerged: 'School as a key setting'; 'What schools should be doing to promote healthy eating (HE)'; 'What schools should be doing to promote physical activity (PA)'; 'General barriers'; 'Barriers to promoting HE at school'; and 'Barriers to promoting PA at school'. Thirty-seven finer-level themes emerged within these categories. Stakeholders agreed on the key role of the primary school as a setting for obesity prevention, the importance of schools providing and promoting opportunities for HE and PA, and the need for schools to work with parents. Some perceived barriers could be overcome at school level, e.g. using unhealthy foods as rewards/fundraisers or withholding PA for bad behaviour. Leadership and guidance from government were considered to be needed to counteract other observed barriers, particularly regarding school canteens, support for parents and time for PA. PMID:23848939

Thirty obese childrenaged 10 to 16 years, with a body mass index (BMI above the 95th percentile according to theclassification proposed by the Centers for Disease Control and Prevention (CDC, 2000, weredivided into two groups: the first group started learning to swim (GSwim, n = 10 and the secondgroup underwent a deep water running program (GDeep, n = 20. Weight, height, BMI, BMIZ-scores, relative and absolute fat, and relative and absolute lean body mass were evaluated atbaseline and after 12 weeks. The program consisted of 12 meetings for nutritional guidance (oncea week and 36 sessions of exercise (three times per week. MANOVA and Fisher’s exact testwere used for statistical analysis, with the level of significance set at p < 0.05. After 12 weeks,GDeep showed a significant reduction in BMI, BMI Z-scores and relative and absolute fat,and an increase in relative and absolute lean body mass. Significant differences were observedbetween GDeep and GSwim in terms of the reduction in body fat (p = 0.014 and the increasein lean mass (p = 0.006. A program of deep water running together with nutritional guidancemay promote significant changes in the body composition of obese children and adolescents dueto the cyclic characteristic of this physical activity.

    Full Text Available Abstract Objectives This paper aims to identify the mediating mechanisms of a school-based obesity prevention program (DOiT. Methods The DOiT-program was implemented in Dutch prevocational secondary schools and evaluated using a controlled, cluster-randomised trial (September 2003 to May 2004. We examined mediators of effects regarding (1 consumption of sugar containing beverages (SCB; (2 consumption of high caloric snacks; (3 screen-viewing behaviour; and (4 active commuting to school. To improve these behaviours the DOiT-program tried to influence the following potentially mediating variables: attitude, subjective norm, perceived behavioural control, and habit-strength. Results Both in boys (n = 418 and girls (n = 436 the DOiT-intervention reduced SCB consumption (between group difference in boys = -303.5 ml/day, 95% CI: -502.4;-104.5, between group difference in girls = -222.3 ml/day, 95% CI: -371.3;-73.2. The intervention did not affect the other examined behaviours. In girls, no intervention effect on hypothetical mediators was found nor evidence of any mediating mechanisms. Boys in intervention schools improved their attitude towards decreasing SCB consumption, while this behaviour became less of a habit. Indeed, attitude and habit strength were significant mediators of the DOiT-intervention's effect (4.5 and 3.8%, respectively on SCB consumption among boys. Conclusion Our findings imply that interventions aimed at EBRB-change should be gender-specific. Future studies aimed at reducing SCB consumption among boys should target attitude and habit strength as mediating mechanisms. Our study did not resolve the mediating mechanisms in girls.

  1. Parents' beliefs about appropriate infant size, growth and feeding behaviour: implications for the prevention of childhood obesity

    Directory of Open Access Journals (Sweden)

    Swift Judy A

    2010-11-01

    Full Text Available Abstract Background A number of risk factors are associated with the development of childhood obesity which can be identified during infancy. These include infant feeding practices, parental response to infant temperament and parental perception of infant growth and appetite. Parental beliefs and understanding are crucial determinants of infant feeding behaviour; therefore any intervention would need to take account of their views. This study aimed to explore UK parents' beliefs concerning their infant's size, growth and feeding behaviour and parental receptiveness to early intervention aimed at reducing the risk of childhood obesity. Method Six focus groups were undertaken in a range of different demographic localities, with parents of infants less than one year of age. The focus groups were audio-recorded, transcribed verbatim and thematic analysis applied using an interpretative, inductive approach. Results 38 parents (n = 36 female, n = 2 male, age range 19-45 years (mean 30.1 years, SD 6.28 participated in the focus groups. 12/38 were overweight (BMI 25-29.99 and 8/38 obese (BMI >30. Five main themes were identified. These were a parental concern about breast milk, infant contentment and growth; b the belief that the main cause of infant distress is hunger is widespread and drives inappropriate feeding; c rationalisation for infants' larger size; d parental uncertainty about identifying and managing infants at risk of obesity and e intentions and behaviour in relation to a healthy lifestyle. Conclusions There are a number of barriers to early intervention with parents of infants at risk of developing obesity. Parents are receptive to prevention prior to weaning and need better support with best practice in infant feeding. In particular, this should focus on helping them understand the physiology of breast feeding, how to differentiate between infant distress caused by hunger and other causes and the timing of weaning. Some parents also need guidance about how to recognize and prepare healthy foods and facilitate physical activity for their infants.

  2. GLP-1 receptor agonist treatment increases bone formation and prevents bone loss in weight-reduced obese women

    Iepsen, Eva W; Lundgren, Julie R

    2015-01-01

    CONTEXT: Recent studies indicate that glucagon-like peptide 1 (GLP-1) regulates bone turnover, but the effects of GLP-1 receptor agonists (GLP-1 RAs) on bone in obese weight-reduced individuals are unknown. OBJECTIVE: To investigate the role of GLP-1 RAs on bone formation and weight loss induced bone mass reductions. DESIGN: Randomized control study. SETTING: Out-patient research hospital clinic. PARTICIPANTS: Thirty-seven healthy obese women. BMI 34±0.5 kg/m(2), age 46±2 years. INTERVENTION: After a low-calorie diet-induced 12% weight loss, participants were randomized to treatment with or without administration of the GLP-1 RA liraglutide (1.2mg/day) for 52 weeks. In case of weight gain, up to two meals per day could be substituted with a low-calorie diet product in order to maintain the weight loss. MAIN OUTCOME MEASURES: Total, pelvic and arm-leg bone mineral content (BMC) and bone markers (CTX-1 and P1NP) were investigated before, after weight loss and after 52 weeks weight maintenance. Primary end points: Change in BMC and bone markers after 52 weeks weight maintenance with or without GLP-1 RA treatment. RESULTS: Total, pelvic and arm-leg BMC decreased during weight maintenance in the control group (p<0.0001), but not significantly in the liraglutide group. Thus, total and arm-leg BMC loss was 4 times greater in the control group compared to the liraglutide group (estimated difference 27g (95% CI 5-48), p=0.01), although the 12% weight loss was maintained in both groups. In the liraglutide group, the bone formation marker P1NP increased by 16% (7±3 ?g/L) vs a 2% (-1±4 ?g/L) decrease in the control group (p<0.05). The bone resorption marker CTX-1 did not change during the weight loss maintenance phase. CONCLUSIONS: Treatment with a long-acting GLP-1 RA increased bone formation by 16% and prevented bone loss after weight loss obtained through a low calorie-diet, supporting its role as a safe weight-lowering agent.

    Reviews of medical malpractice claims against ophthalmologists have revealed a pattern of misunderstanding and improper or underutilization of several risk prevention and defense techniques. This often results in increasing the risk of litigation and weakening the defense of the claims. These techniques include the physician-attorney relationship, dealing with differences in the patient's version of the facts versus that of the physician (he said-she said), the physician-patient relationship, informed refusal, awareness of whom we are trying to convince with our arguments, vicarious liability, subpoena duces tecum, the most dangerous diagnosis, and the management of unethical plaintiff witnesses. Many of these techniques have been extensively described in the literature. This article discusses the means by which to make optimal use of them in order to achieve maximal risk prevention and the strongest possible defense in the event of litigation. PMID:19171218

    Hemmingsson, E

    2014-09-01

    The lack of significant treatment and prevention progress highlights the need for a more expanded strategy. Given the robust association between socioeconomic factors and obesity, combined with new insights into how socioeconomic disadvantage affects both behaviour and biology, a new causal model is proposed. The model posits that psychological and emotional distress is a fundamental link between socioeconomic disadvantage and weight gain. At particular risk are children growing up in a disharmonious family environment, mainly caused by parental socioeconomic disadvantage, where they are exposed to parental frustrations, relationship discord, a lack of support and cohesion, negative belief systems, unmet emotional needs and general insecurity. Without adequate resilience, such experiences increase the risk of psychological and emotional distress, including low self-esteem and self-worth, negative emotions, negative self-belief, powerlessness, depression, anxiety, insecurity and a heightened sensitivity to stress. These inner disturbances eventually cause a psycho-emotional overload, triggering a cascade of weight gain-inducing effects including maladaptive coping strategies such as eating to suppress negative emotions, chronic stress, appetite up-regulation, low-grade inflammation and possibly reduced basal metabolism. Over time, this causes obesity, circular causality and further weight gain. Tackling these proposed root causes of weight gain could potentially improve both treatment and prevention outcomes.

  15. Effects of macronutrient composition and cyclooxygenase-inhibition on diet-induced obesity, low grade inflammation and glucose homeostasis

    DEFF Research Database (Denmark)

    Fjære, Even

    2012-01-01

    Background: Obesity and its related metabolic complications are an increasing problem worldwide. A high fat diet in combination with sucrose has been shown to induce obesity and development of glucose intolerance and insulin resistance in rodents. C57BL/6J mice were fed high fat diets with sucrose- or protein based background, and supplemented with either corn- or fish oil. These experiments were conducted to determine whether macronutrient composition and type of dietary fat can modulate diet-induced obesity, and associated metabolic consequences. The use of non-steroidal anti-inflammatory drugs is escalating, and in view of the increased consumption of obesogenic diets with high levels of dietary carbohydrates and fat, the metabolic consequences of cyclooxygenase-inhibition warrants investigation. Results: High fat/high sucrose diets increased obesity development and expression of macrophage infiltration markers in the adipose tissue. By increasing the amount of dietary protein, at the expanse of sucrose, the obesogenic effect of the HF diet was prevented. The reduced obesogenic effect of the high fat/high protein diet was associated with increased expression of genes related to hepatic gluconeogenesis and ureagenesis, in addition to genes related to thermogenesis. Fish oil enriched diets with polyunsaturated omega-3 fatty acids, are shown to prevent diet-induced obesity, however, this effect was blunted with increased sucrose content in the diet. The obesogenic high fat/high diet in combination with indomethacin, a nonselective cyclooxygenase cyclooxygenase-inhibitor, reduces energy efficiency and fat mass in C57BL/6J mice. Despite prevention of obesity development, indomethacin treatment was associated with hyperglycemia and reduced glucose tolerance. Body weight was not affected when indomethacin was combined with a low fat diet. This further highlights the importance of the background diet and macronutrient composition of experimental diets. Conclusions: In summary, our results demonstrate that the composition of background diet modulates the obesogenic effect of the high fat diet. The obesogenic effect of a high fat/ high sucrose diet can also be prevented with inclusion of indomethacin in the diet.

    Snowdon, W; Thow, A M

    2013-11-01

    The Pacific Island countries experience some of the highest rates of obesity in the world in part due to substantial dietary changes that mirror changes in the food supply in the region. Economic and political ties, donor aid, and trade links are key drivers of the changing availability and accessibility of processed and imported foods. Pacific Island countries have been innovative in developing trade-related policy approaches to create a less obesogenic food environment. Taxation-based approaches that affect pricing in the region include increased import and excise tariffs on sugared beverages and other high-sugar products, monosodium glutamate, and palm oil and lowered tariffs on fruits and vegetables. Other approaches highlight some higher-fat products through labeling and controlling the supply of high-fat meats. The bans on high-fat turkey tails and mutton flaps highlight the politics, trade agreements and donor influences that can be significant barriers to the pursuit of policy options. Countries that are not signatories to trade agreements may have more policy space for innovative action. However, potential effectiveness and practicality require consideration. The health sector's active engagement in the negotiation of trade agreements is a key way to support healthier trade in the region. PMID:24102909

  19. Ablation of insulin-producing cells prevents obesity but not premature mortality caused by a high-sugar diet in Drosophila.

    Ageing can be modulated by genetic as well as nutritional interventions. In female Drosophila melanogaster, lifespan is maximized at intermediate concentrations of sucrose as the carbohydrate source, and yeast as the protein source. Dampening the signal through the insulin/IGF signalling (IIS) pathway, by genetic ablation of median neurosecretory cells (mNSCs) that produce insulin-like peptides, extends lifespan and counteracts the detrimental effects of excess yeast. However, how IIS reduction impacts health on a high-sugar diet remains unclear. We find that, while the ablation of the mNSCs can extend lifespan and delay the age-related decline in the health of the neuromuscular system irrespective of the amount of dietary sugar, it cannot rescue the lifespan-shortening effects of excess sugar. On the other hand, ablation of mNSCs can prevent adult obesity resulting from excess sugar, and this effect appears independent from the canonical effector of IIS, dfoxo. Our study indicates that while treatments that reduce IIS have anti-ageing effects irrespective of dietary sugar, additional interventions may be required to achieve full benefits in humans, where excessive sugar consumption is a growing problem. At the same time, pathways regulated by IIS may be suitable targets for treatment of obesity. PMID:25520354

    Full Text Available The prevalence of overweight and obesity and their associated metabolic disorders are considered a major threat to the public’s health. While several diet and exercise programs are available for weight loss and prevention of weight regain, progress is often slow and disappointing. Recently, natural bioactive phytochemicals present in foods have been discovered for their potential health benefit effects on the prevention of chronic disorders such as cancer, cardiovascular disease, inflammatory and metabolic diseases including obesity.Polyphenols are a class of naturally-occurring phytochemicals, of which some such as catechins, anthocynines, resveratrol and curcumin have been shown to modulate physiological and molecular pathways that are involved in energy metabolism, adiposity, and obesity. The potential in vivo, beneficial effects of these polyphenols on adiposity and obesity as complementary agents in the up-regulation of energy expenditure have emerged by investigating these compounds in cell cultures, animal models of obesity and in some human clinical and epidemiological studies. In this brief review, the efficacy of the above-named polyphenols and their potential efficacy to modulate obesity and some associated disorders are discussed.

    Recent findings have uncovered intimate relationships between circadian clocks and energy metabolism. Epidemiological studies have shown that the frequency of obesity and metabolic disorders increases among shift-workers. Here we found that a chronic shift in light/dark (LD) cycles comprising an advance of six hours twice weekly, induced obesity in mice. Under such conditions that imitate jet lag/shift work, body weight and glucose intolerance increased, more fat accumulated in white adipose tissues and the expression profiles of metabolic genes changed in the liver compared with normal LD conditions. Mice fed at a fixed 12 h under the LD shift notably did not develop symptoms of obesity despite isocaloric intake. These results suggest that jet lag/shift work induces obesity as a result of fluctuating feeding times and it can be prevented by fixing meal times. This rodent model of obesity might serve as a useful tool for understanding why shift work induces metabolic disorders. PMID:26297949

    2010-01-01

    Overweight and obesity have adverse metabolic effects on blood pressure, blood lipids and insulin resistance, consequently increasing the risk of chronic diseases such as type 2 diabetes, cardiovascular diseases, and even certain forms of cancer. Together with abdominal obesity, insulin resistance plays a principal role in initiating and perpetuating the pathological manifestations of the metabolic syndrome. Obesity results from the combined effects of genes, environment and lifestyle. In thi...

    Maternal obesity during pregnancy has been linked to an increased risk of obesity and cardiometabolic disease in the offspring, a phenomenon attributed to developmental programming. Programming effects may be transmissible across generations through both maternal and paternal inheritance, although the mechanisms remain unclear. Using a mouse model, we explored the effects of moderate maternal diet-induced obesity (DIO) on weight gain and glucose-insulin homeostasis in first-generation (F1) an...

    Full Text Available Abstract Background Despite the growing emphasis on the inclusion of ethnic minority patients in research, there is little published on the recruitment of these populations especially to randomised, community based, lifestyle intervention trials in the UK. Methods We share our experience of recruitment to screening in the PODOSA (Prevention of Diabetes and Obesity in South Asians trial, which screened 1319 recruits (target 1800 for trial eligibility. A multi-pronged recruitment approach was used. Enrolment via the National Health Service included direct referrals from health care professionals and written invitations via general practices. Recruitment within the community was carried out by both the research team and through our partnerships with local South Asian groups and organisations. Participants were encouraged to refer friends and family throughout the recruitment period. Results Health care professionals referred only 55 potential participants. The response to written invitations via general practitioners was 5.2%, lower than reported in other general populations. Community orientated, personal approaches for recruitment were comparatively effective yielding 1728 referrals (82% to the screening stage. Conclusions The PODOSA experience shows that a community orientated, personal approach for recruiting South Asian ethnic minority populations can be successful in a trial setting. We recommend that consideration is given to cover recruitment costs associated with community engagement and other personalised approaches. Researchers should consider prioritising approaches that minimise interference with professionals' work and, particularly in the current economic climate, keep costs to a minimum. The lessons learned in PODOSA should contribute to future community based trials in South Asians. Trial Registration Current Controlled Trials ISRCTN25729565

  5. Diabetes preventive gluten-free diet decreases the number of caecal bacteria in non-obese diabetic mice

    Hansen, Axel Kornerup; Ling, Fenjung

    2006-01-01

    Background A gluten-free diet reduces the incidence of diabetes mellitus in non-obese diabetic (NOD) mice, but the mechanism is not known. The aim of this study was to examine the possible influence of the diet on the caecal bacterial flora, which may affect the intestinal physiology and mediate disease prevention. Methods Two groups of NOD mice from the age of 3 weeks were fed either a gluten-free diet or a standard diet. Each diabetic mouse, when diagnosed, along with a non-diabetic mouse from the same diet group and two nondiabetic mice from the alternate diet group were euthanized and sampled for classical bacteriological examination. Results Nine out of 19 (47%) standard-fed mice and 1 out of 19 (5%) gluten-free-fed mice developed diabetes (p < 0.01). Mice on the gluten-free diet had significantly fewer aerobically (p < 0.01) and microaerophilically (p < 0.001) cultivated bacteria in their intestines than standard-fed mice. Non-diabetic mice also had significantly fewer microa erophilic and anaerobic bacteria than diabetic mice (p < 0.05). These differences were primarily due to a difference in the Gram-positive flora. Conclusions The gluten-free diet compared to the standard diet both qualitatively and quantitatively substantially altered the composition of the caecal bacterial flora in NOD mice. Although Gram-positive bacteria might influence the beta cells through certain digestive products, it is more likely to assume that any effect on diabetes incidence is immunological.

  10. Peer Effects on Obesity in a Sample of European Children

    DEFF Research Database (Denmark)

    Gwozdz, Wencke; Sousa-Poza, Alfonso

    2015-01-01

    This study analyzes peer effects on childhood obesity using data from the first two waves of the IDEFICS study, which applies several anthropometric and other measures of fatness to approximately 14,000 children aged two to nine participating in both waves in 16 regions of eight European countries. Peers are defined as same-sex children in the same school and age group. The results show that peer effects do exist in this European sample but that they differ among both regions and different fatness measures. Peer effects are larger in Spain, Italy, and Cyprus – the more collectivist regions in our sample – while waist circumference generally gives rise to larger peer effects than BMI. We also provide evidence that parental misperceptions of their own children's weight goes hand in hand with fatter peer groups, supporting the notion that in making such assessments, parents compare their children's weight with that of friends and schoolmates.

  11. Tackling inequalities in obesity: a protocol for a systematic review of the effectiveness of public health interventions at reducing socioeconomic inequalities in obesity amongst children

    2012-02-01

    Full Text Available Abstract Background There is growing evidence of the impact of overweight and obesity on short- and long-term functioning, health and well-being. Internationally, childhood obesity rates continue to rise in some countries (for example, Mexico, India, China and Canada, although there is emerging evidence of a slowing of this increase or a plateauing in some age groups. In most European countries, the United States and Australia, however, socioeconomic inequalities in relation to obesity and risk factors for obesity are widening. Addressing inequalities in obesity, therefore, has a very high profile on the public health and health services agendas. However, there is a lack of accessible policy-ready evidence on what works in terms of interventions to reduce inequalities in obesity. Methods and design This article describes the protocol for a National Health Service Trust (NHS National Institute for Health Research-funded systematic review of public health interventions at the individual, community and societal levels which might reduce socioeconomic inequalities in relation to obesity amongst children ages 0 to 18 years. The studies will be selected only if (1 they included a primary outcome that is a proxy for body fatness and (2 examined differential effects with regard to socioeconomic status (education, income, occupation, social class, deprivation and poverty or the intervention was targeted specifically at disadvantaged groups (for example, children of the unemployed, lone parents, low income and so on or at people who live in deprived areas. A rigorous and inclusive international literature search will be conducted for randomised and nonrandomised controlled trials, prospective and retrospective cohort studies (with and/or without control groups and prospective repeat cross-sectional studies (with and/or without control groups. The following electronic databases will be searched: MEDLINE, Embase, CINAHL, PsycINFO, Social Science Citation Index, ASSIA, IBSS, Sociological Abstracts and the NHS Economic Evaluation Database. Database searches will be supplemented with website and grey literature searches. No studies will be excluded on the basis of language, country of origin or publication date. Study inclusion, data extraction and quality appraisal will be conducted by two reviewers. Meta-analysis and narrative synthesis will be conducted. The main analysis will examine the effects of (1 individual, (2 community and (3 societal level public health interventions on socioeconomic inequalities in childhood obesity. Interventions will be characterised by their level of action and their approach to tackling inequalities. Contextual information on how such public health interventions are organised, implemented and delivered will also be examined. Discussion In this review, we consider public health strategies which reduce and prevent inequalities in the prevalence of childhood obesity, highlight any gaps in the evidence base and seek to establish how such public health interventions are organised, implemented and delivered.

    HT048 is a combination composed of Crataegus pinnatifida leaf and Citrus unshiu peel extracts. This study aimed to investigate potential anti-obesity effect of the combination. The 3T3-L1 adipocytes were treated with different doses of HT048 and triglyceride accumulation, glycerol release and adipogenesis-related genes were analyzed. For in vivo study, male Sprague Dawley rats were divided according to experimental diets: the chow diet group, the high-fat diet (HFD) group, the HFD supplemented with orlistat group, the HFD supplemented with HT048 group (0.2% or 0.4%) for 12 weeks. We measured the body weight, serum lipid levels and the expression of genes involved lipid metabolism. HT048 treatment dose-dependently suppressed adipocyte differentiation and stimulated glycerol release. The expressions of PPAR? and C/EBP? mRNA were decreased by HT048 treatment in adipocytes. HT048 supplementation significantly reduced the body and fat weights in vivo. Serum lipid levels were significantly lower in the HT048 supplemented groups than those of the HFD group. Expression of the hepatic lipogenesis-related genes were decreased and expression of the ?-oxidation-related genes were increased in rats fed HT048 compared to that of animals fed HFD. These results suggest that HT048 has a potential benefit in preventing obesity through the inhibition of lipogenesis and adipogenesis. PMID:26016552

    Full Text Available ABSTRACT Objective To describe and contrast individual state nutrition and physical activity regulations related to childhood obesity for child care centers and family child care homes in the United States. Methods We conducted a review of regulations for child care facilities for all 50 states and the District of Columbia. We examined state regulations and recorded key nutrition and physical activity items that may contribute to childhood obesity. Items included in this review were: 1 Water is freely available; 2 Sugar-sweetened beverages are limited; 3 Foods of low nutritional value are limited; 4 Children are not forced to eat; 5 Food is not used as a reward; 6 Support is provided for breastfeeding and provision of breast milk; 7 Screen time is limited; and 8 Physical activity is required daily. Results Considerable variation exists among state nutrition and physical activity regulations related to obesity. Tennessee had six of the eight regulations for child care centers, and Delaware, Georgia, Indiana, and Nevada had five of the eight regulations. Conversely, the District of Columbia, Idaho, Nebraska and Washington had none of the eight regulations. For family child care homes, Georgia and Nevada had five of the eight regulations; Arizona, Mississippi, North Carolina, Oregon, Tennessee, Texas, Vermont, and West Virginia had four of the eight regulations. California, the District of Columbia, Idaho, Iowa, Kansas, and Nebraska did not have any of the regulations related to obesity for family child care homes. Conclusion Many states lack specific nutrition and physical activity regulations related to childhood obesity for child care facilities. If widely implemented, enhancing state regulations could help address the obesity epidemic in young children in the United States.

    Childhood cancer survivors are at an increased risk of obesity but causes for this elevated risk are uncertain. We evaluated total energy expenditure in childhood cancer survivors using the doubly labeled water method in a cross-sectional study of 17 survivors of pediatric leukemia or lymphoma (median age, 11.5 y). Mean total energy expenditure was 2073 kcal/d, which was nearly 500 kcal/d lower than estimated energy requirements with recommended levels of physical activity. This energy gap is likely to contribute to the risk of obesity in this population and future trials are needed to assess implications and potential treatment strategies. PMID:25197775

    Full Text Available Abstract Background Given the increase in overweight and obesity prevalence in adolescents in the last decade, effective prevention strategies for these conditions in adolescents are urgently needed. The PRALIMAP (Promotion de l'ALImentation et de l'Activité Physique trial aims to evaluate the effectiveness for these conditions of 3 health promotion strategies -- educational, screening and environmental -- applied singly or in combination in high schools over a 2-year intervention period. Methods PRALIMAP is a stratified 2 × 2 × 2 factorial cluster randomised controlled trial including 24 state high schools in Lorraine, northeastern France, in 2 waves: 8 schools in 2006 (wave 1 and 16 in 2007 (wave 2. Students entering the selected high schools in the 4 academic years from 2006 to 2009 are eligible for data collection. Interventional strategies are organized over 2 academic years. The follow-up consists of 3 visits: at the entry of grade 10 (T0, grade 11 (T1 and grade 12 (T2. At T0, 5,458 (85.7% adolescents participated. The educational strategy consists of nutritional lessons, working groups and a final party. The screening strategy consists in detecting overweight/obesity and eating disorders in adolescents and proposing, if necessary, an adapted care management program of 7 group educational sessions. The environmental strategy consists in improving dietary and physical activity offerings in high schools and facilities, especially catering. The main outcomes are body size evolution over time, nutritional behaviour and knowledge, health and quality of life. An evaluation process documents how each intervention strategy is implemented in the schools and estimates the dose of the intervention, allowing for a per protocol analysis after the main intention-to-treat analysis. Discussion PRALIMAP aims at improving the prevention and management of overweight and obesity in adolescents by translating current evidence into public health practice. Particular attention is paid to clustering, multiple factorials and long-term duration to address common pitfalls in health promotion trials. The results should inform how best to implement, in a school environment, effective nutrition prevention programs targeting adolescents who are at a point their lives when they develop responsibilities and empowerment for health attitude behaviours. Trial registration This trial is registered at ClinicalTrials.gov under NCT00814554.

    Full Text Available Abstract Background The rhizomes of Panax japonicus are used as a folk medicine for treatment of life-style related diseases such as arteriosclerosis, hyperlipidemia, hypertension and non-insulin-dependent diabetes mellitus as a substitute for ginseng roots in China and Japan. Obesity is closely associated with life-style-related diseases. This study was performed to clarify whether chikusetsusaponins prevent obesity induced in mice by a high-fat diet for 9 weeks. Methods We performed two in vivo experiments. In one, female ICR mice were fed a high-fat diet with or without 1 or 3% chikusetsusaponins isolated from P. japonicus rhizomes for 9 weeks. In the other, lipid emulsion with or without chikusetsusaponins was administered orally to male Wistar rats, and then the plasma triacylglycerol level was measured 0.5 to 5 h after the orally administered lipid emulsion. For in vitro experiments, the inhibitory effects of total chikusetsusaponins and various purified chikusetsusaponins on pancreatic lipase activity were determined by measuring the rate of release of oleic acid from triolein in an assay system using triolein emulsified with lecithin. Results Total chikusetsusaponins prevented the increases in body weight and parametrial adipose tissue weight induced by a high-fat diet. Furthermore, consumption of a high-fat diet containing 1 or 3% total chikusetsusaponins significantly increased the fecal content and triacylglycerol level at day 3 compared with the high-fat diet groups. Total chikusetsusaponins inhibited the elevation of the plasma triacylglycerol level 2 h after the oral administration of the lipid emulsion. Total chikusetsusaponins, chikusetsusaponin III, 28-deglucosyl-chikusetsusaponin IV and 28-deglucosyl-chikusetsusaponin V inhibited the pancreatic lipase activity. Conclusion The anti-obesity effects of chikusetsusaponins isolated from P. japonicus rhizomes in mice fed a high-fat diet may be partly mediated through delaying the intestinal absorption of dietary fat by inhibiting pancreatic lipase activity. The present study clearly indicated that the saponin fractions of P. japonicus rhizomes had a significant anti-obesity action and supports the traditional usage as a substitute drug for ginseng roots.
