Background Nearly 50% of Canadians are overweight and their number is increasing rapidly. The majority of obese subjects are treated by primary care physicians (PCPs) who often feel uncomfortable with the management of obesity. The current research proposal is aimed at the development and implementation of an innovative, integrated, interdisciplinary obesity care management system involving both primary and secondary care professionals. Methods We will use both action and evaluative research in order to achieve the following specific objectives. The first one is to develop and implement a preceptorship-based continuing medical education (CME) program complemented by a web site for physicians and nurses working in Family Medicine Groups (FMGs). This CME will be based on needs assessment and will be validated by one FMG using questionnaires and semi structured interviews. Also, references and teaching tools will be available for participants on the web site. Our second objective is to establish a collaborative intra and inter-regional interdisciplinary network to enable on-going expertise update and networking for FMG teams. This tool consists of a discussion forum and monthly virtual meetings of all participants. Our third objective is to evaluate the implementation of our program for its ability to train 8 FMGs per year, the access and utilization of electronic tools and the participants' satisfaction. This will be measured with questionnaires, web logging tools and group interviews. Our fourth objective is to determine the impact for the participants regarding knowledge and expertise, attitudes and perceptions, self-efficacy for the management of obesity, and changes in FMG organization for obesity management. Questionnaires and interviews will be used for this purpose. Our fifth objective is to deliver transferable knowledge for health professionals and decision-makers. Strategies and pitfalls of setting up this program will also be identified. Conclusion This
Obesity disease management opportunities and barriers.
Sidorov, Jaan E; Fitzner, Karen
2006-04-01
Disease management, a system of coordinated health care interventions and communications for chronically ill populations, relies on patient education and case management to engage individuals in the management of their condition. Disease management also aims to enhance the quality of interactions between doctors and patients and advance evidence-based medicine. Because these programs' interventions frequently include helping individuals who suffer comorbidities associated with obesity to reduce their BMI, adaptation of disease management to populations with obesity seems a viable option. A major barrier for implementing disease management for obesity, however, is the lack of proven return on investment, which limits health plan and disease management organization interest. Purchaser demand may overcome this reluctance. Further research is needed to objectively test whether disease management interventions would be clinically effective for obese populations, produce positive financial outcomes for insurers, and enhance workplace productivity.
Unmet needs in obesity management: From guidelines to clinic.
Ritten, Angela; LaManna, Jacqueline
2017-10-01
Despite the rather slow acceptance of obesity as a disease state, several obesity staging systems and weight-management guidelines have been developed and are in use, along with an ever-growing number of treatment options. Many primary care clinicians, including nurse practitioners (NPs), are at the forefront of clinical efforts to assist individuals with obesity, but face challenges due to lack of alignment and consensus among the various staging systems and guidelines. This is further complicated by shortfalls in clinical training related to obesity management and increasing complexities in reimbursement for obesity-related services. Unmet needs in the management of obesity thus stretch from guidelines to clinic. This article examines the principal barriers to effective management of individuals with obesity and considers how concerns might be overcome, with particular emphasis on the role of the NP. ©2017 American Association of Nurse Practitioners.

Despite the strong recommendations of guidelines, intensive obesity management is not offered to all obese patients. This study aimed to examine differences in obesity management between primary care physicians (PCPs) and non-PCPs. A cross-sectional study was performed using the 2006-2007 National Ambulatory Medical Care Survey. Adults (age ≥20 years) with obesity (body mass index (BMI)≥30 kg/m(2) or obesity diagnosis using International Classification of Diseases, Ninth Revision, Clinical Modification code 278) were included in the study cohort. A multivariate logistic regression model was constructed to examine differences between PCPs and non-PCPs (primary independent variable) for obesity management (dependent variable) while controlling for predisposing, enabling, and need characteristics per Anderson's behavioral model. In all, 32.66% of 214 million visits by obese patients in 2006-2007 resulted in obesity management. PCPs were 2.38 times more likely to provide obesity management compared to non-PCPs (odds ratio [OR]=2.37; 95% confidence interval [CI]: 1.69, 3.36). Patients who had preventive visits (OR=2.23; 95% CI: 1.50, 3.32) and chronic visits (OR=1.93; 95% CI: 1.46, 2.55) were more likely to receive obesity management than patients who had acute visits. More time spent with physician, more comorbid conditions, and BMI ≥ 40 significantly increased the likelihood of receiving obesity management, while older age and smoking reduced the likelihood of receiving obesity management. Only one third of ambulatory care visits in 2006-2007 resulted in obesity management. A difference in obesity management was noted between PCPs and non-PCPs. Future research should aim to identify the reasons for these observed differences, ensure equitable access, and address the undertreatment of obesity.
Obesity weight management and bariatric surgery case management programs: a review of literature.
Echols, Jennie
2010-01-01
The proportion of Americans with clinically severe obesity has vast implications for the nation's healthcare system since this population have twice as many chronic medical conditions as people with normal weight. Through the use of review of literature, this article (a) describes the types of weight loss programs; (b) reviews the results from studies on effectiveness of bariatric surgery; and (c) identifies recommendations for obesity and bariatric surgery case management programs. Disease management companies appear to be concentrating on general weight loss strategies associated with wellness and other condition-specific disease management products, whereas larger national healthcare companies with at-risk and insurance products offer specific bariatric surgery management products. Case management programs within healthcare systems, health management organizations, and insurance companies are frequently faced with the management of individuals with morbid obesity and, increasingly, those who are requesting or have undergone bariatric surgery. Research shows that morbid obesity is a disease that remains generally unresponsive to diet and drug therapy but appears to respond well to bariatric surgery. Research findings suggest that surgical treatment is more effective than pharmacological treatment of weight loss and the control of some comorbidities associated with obesity. The number of Americans having weight loss surgery increased by 804% between 1998 and 2004, which appears to be a driver for the recent development of obesity disease management and bariatric surgery case management programs. Although the immaturity and lack of studies citing outcomes of obesity disease and case management programs limit the identification of best practices based on outcomes, emerging practices can be identified and recommendations for case management can be formulated. In addition to primary prevention and treatment programs for obesity, this article describes program
The pharmacological treatment and management of obesity.
Hussain, Syed Sufyan; Bloom, Stephen Robert

Obesity is a pandemic with many complications that increase the societal disease burden and cost of health care, and decrease longevity and quality of life. Currently, 1 in 3 adults in the United States is obese. Physicians must therefore regularly confront obesity and its consequent diseases, and develop strategies for effective treatment and management. This article summarizes current lifestyle modifications, pharmacological treatment, and surgical options for the management of obesity and discusses the benefits, limitations, and risks of each. As insights are gained into the pathophysiology of a gut-brain neurochemical feedback axis governing satiety and feeding behavior, targets for new pharmacotherapies are being developed. In particular, gut hormone analogs are an attractive antiobesity therapy because they appear to lack the adverse effects historically associated with central nervous system-acting agents.
Managing obesity in primary care.
Goldie, Christine; Brown, Jenny
Obesity is a complex problem and often difficult to tackle in primary care. A year-long pilot of a practice nurse-led scheme that used a holistic approach towards self-care in obesity management was set up to reduce the cardiovascular risk of patients who were obese and improve their quality of life. This person-centred approach may offer an important tool in the management of these patients in the GP surgery.
Obesity management in Prader-Willi syndrome.
Salehi, Parisa; Leavitt, Anne; Beck, Anita E; Chen, Maida L; Roth, Christian L
2015-03-01
Prader-Willi Syndrome (PWS) is one of the most common genetic causes of obesity. The phenotype of obesity in PWS is unique and characterized by hyperphagia, earlier meal initiation, delayed meal termination, reduced energy expenditure, abnormal gut hormone profiles, as well as irregular responses to food in areas of the brain associated with satiety and reward. Management of obesity is necessary to avoid major morbidity. The relentless food-seeking behavior associated with PWS such as stealing, hoarding food, eating inedibles, and lying about eating, can cause turmoil both inside and outside of the home. Management is challenging for both patients and caretakers, but at this time there are limited medical therapies available besides dietary restriction and behavior management. However, current research shows promise for discovery of additional treatment options for hyperphagia and obesity management in PWS.
Midwifery Management of Pregnant Women Who Are Obese.

Obesity is associated with increased risks for adverse health outcomes during and after pregnancy in both the woman with obesity and her infant. This study was designed to investigate midwifery management of pregnant women with obesity. Certified midwives and certified nurse-midwives who were members of the American College of Nurse-Midwives were sent a survey. The survey instrument was divided into 4 sections: demographic characteristics; practice guidelines and protocols; the role of the 2015 Levels of Maternal Care guidelines for referral, including transfer to a higher level of care; and factors that influence management of pregnant women with obesity. Descriptive statistics were used to analyze data. In a sample of 546 midwives, 87% of respondents reported observing an increase in perinatal complications associated with obesity. Midwives reported increasing discomfort with the care of pregnant women with obesity as body mass index (BMI) increased. For pregnant women with extreme obesity, the respondents reported less frequent use of physiologic birth guidelines only and increased use of interventions, referral to physician care, and transfer to a higher level of care. Approximately half (270, 49.5%) reported having a guideline that addressed the care of women with obesity. Of these, 145 midwives (53.7%) reported that extreme obesity was the BMI threshold for identifying an increased or high risk for perinatal complications. Sixty percent (339) of midwives who participated requested guidance for management of laboring women who are obese. This study provides a greater understanding of midwifery management practices when caring for women with obesity and opportunities to improve care. The results suggest that midwifery management alters with increased BMI, specifically in the care of women with extreme obesity. Suggestions for future study include research on management of pregnant women with obesity and extreme obesity with outcome data examining management

Obesity is a chronic metabolic disease characterised by an increase of body fat stores. It is a gateway to ill health, and it has become one of the leading causes of disability and death, affecting not only adults but also children and adolescents worldwide. In clinical practice, the body fatness is estimated by BMI, and the accumulation of intra-abdominal fat (marker for higher metabolic and cardiovascular disease risk) can be assessed by waist circumference. Complex interactions between biological, behavioural, social and environmental factors are involved in regulation of energy balance and fat stores. A comprehensive history, physical examination and laboratory assessment relevant to the patient's obesity should be obtained. Appropriate goals of weight management emphasise realistic weight loss to achieve a reduction in health risks and should include promotion of weight loss, maintenance and prevention of weight regain. Management of co-morbidities and improving quality of life of obese patients are also included in treatment aims. Balanced hypocaloric diets result in clinically meaningful weight loss regardless of which macronutrients they emphasise. Aerobic training is the optimal mode of exercise for reducing fat mass while a programme including resistance training is needed for increasing lean mass in middle-aged and overweight/obese individuals. Cognitive behavioural therapy directly addresses behaviours that require change for successful weight loss and weight loss maintenance. Pharmacotherapy can help patients to maintain compliance and ameliorate obesity-related health risks. Surgery is the most effective treatment for morbid obesity in terms of long-term weight loss. A comprehensive obesity management can only be accomplished by a multidisciplinary obesity management team. We conclude that physicians have a responsibility to recognise obesity as a disease and help obese patients with appropriate prevention and treatment. Treatment should be based on
Improving Obesity Prevention and Management in Primary Care in Canada.
Campbell-Scherer, Denise; Sharma, Arya Mitra
2016-09-01
Obesity is a major risk factor for chronic diseases with significant morbidity, mortality and health care cost. There is concern due to the dramatic increase in overweight and obesity in Canada in the last 20 years. The causes of obesity are multifactorial, with underestimation by patients and healthcare providers of the long-term nature of the condition, and its complexity. Solutions related to prevention and management will require multifaceted strategies involving education, health policy, public health and health systems across the care continuum. We believe that to support such strategies we need to have a strong primary care workforce equipped with appropriate knowledge, skills and attitudes to support persons at risk for, or with, obesity. To achieve this end, significant skills building is required to improve primary care obesity prevention and management efforts. This review will first examine the current state, and then will outline how we can improve.
Developing a holistic approach to obesity management.
Brown, Jenny; Wimpenny, Peter
2011-02-01
The aim of this paper is to discuss the theoretical background and relevance of a holistic approach to obesity management by nurses. There is a global rise in the number of people with obesity, such that it now represents one of the major health challenges. However, nurses are often influenced by physical and dietetic focused approaches and could fail to acknowledge a range of other factors that can impact on weight management. As part of the development of a holistic approach to obesity a literature search was undertaken to establish relevant theoretical perspectives that underpin practice in physical, psychological and social aspects of care (focused on the period 1995-2005). In addition, experiences of working in a secondary care weight management clinic were also drawn upon. Psychobiological, attribution and social support theories were identified that could contribute to a better understanding of obesity. If these theoretical perspectives and supporting evidence can be integrated in a holistic approach to care and management it might be possible to promote better health and well-being in those with obesity. Creating a greater understanding of the range of theoretical perspectives and supporting evidence related to obesity could, it is argued, provide enhanced care and management. © 2011 Blackwell Publishing Asia Pty Ltd.
[Role of probiotics in obesity management].
Prados-Bo, Andreu; Gómez-Martínez, Sonia; Nova, Esther; Marcos, Ascensión
2015-02-07
Obesity is a major public health issue as it is related to several chronic disorders, including type-2 diabetes, high blood pressure, dyslipemia, cardiovascular diseases and cancer, among others. Novel research shows that the gut microbiota is involved in obesity and metabolic disorders, revealing that obese animal and human subjects have alterations in the composition of the gut microbiota compared to their lean counterparts. Moreover, it has been observed in germ-free mice that transplantation of the microbiota of either obese or lean mice influences body weight, suggesting that the gut ecosystem is a relevant target for weight management. Certain strains of probiotics may regulate body weight by influencing the host's metabolic, neuroendocrine and immune functions. Taken together, our knowledge about the influence of gut microbiota on obesity is progressing. Therefore, modulation of its composition through probiotics may provide new opportunities to manage overweight and obesity. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

The role of managed care organizations in obesity management.
Schaecher, Kenneth L
2016-06-01
In the United States, obesity is characterized as this century's greatest healthcare threat. The American Medical Association and several other large organizations now classify obesity as a disease. Several federal initiatives are in the planning stages, have been approved, or are being implemented to address the disease. Obesity poses challenges for all healthcare stakeholders. Diet and exercise often are insufficient to create the magnitude of change patients and their attending healthcare providers need. Managed care organizations (MCOs) have 3 tools that can help their members: health and wellness programs focusing on lifestyle changes, prescription weight-loss drugs, and bariatric surgical interventions. MCOs are addressing changes with national requirements and are responding to the availability of new weight-loss drugs to help their members achieve better health. A number of factors either deter or stimulate the progress of weight loss therapy. Understanding how MCOs are key to managing obesity at the local level is important for healthcare providers. It can help MCOs and individual healthcare providers develop and coordinate strategies to educate stakeholders and better manage overall care.
How does obesity affect the endocrine system? A narrative review.
Poddar, M; Chetty, Y; Chetty, V T
2017-06-01
Obesity is a chronic, relapsing medical condition that results from an imbalance of energy expenditure and consumption. It is a leading cause of preventable illness, disability and premature death. The causes of obesity are multifactorial and include behavioural, socioeconomic, genetic, environmental and psychosocial factors. Rarely are endocrine diseases, e.g., hypothyroidism or Cushing's syndrome, the cause of obesity. What is less understood is how obesity affects the endocrine system. In this review, we will discuss the impact of obesity on multiple endocrine systems, including the hypothalamic-pituitary axis, changes in vitamin D homeostasis, gender steroids and thyroid hormones. We will also examine the renin angiotensin aldosterone system and insulin pathophysiology associated with obesity. We will provide a general overview of the biochemical changes that can be seen in patients with obesity, review possible aetiologies of these changes and briefly consider current guidelines on their management. This review will not discuss endocrine causes of obesity. © 2017 World Obesity Federation.

We did not find any paper that assessed clinical inertia in obese patients. Therefore, no paper has compared the clinical inertia rates between morbidly and nonmorbidly obese patients. A cross-sectional observational study was carried out. We analysed 8687 obese patients ⩾40 years of age who attended their health-care center for a checkup as part of a preventive program. The outcome was morbid obesity. Secondary variables were as follows: failure in the management of high blood pressure (HBP), high blood cholesterol (HBC) and high fasting blood glucose (HFBG); gender; personal history of hypertension, dyslipidemia, diabetes, smoking and cardiovascular disease; and age (years). We analysed the association between failures and morbid obesity by calculating the adjusted odds ratio (OR). Of 8687 obese patients, 421 had morbid obesity (4.8%, 95% confidence interval (CI): 4.4-5.3%). The prevalence rates for failures were as follows: HBP, 34.7%; HBC, 35.2%; and HFBG, 12.4%. Associated factors with morbid obesity related with failures were as follows: failure in the management of HBP (OR=1.42, 95% CI: 1.15-1.74, P=0.001); failure in the management of HBC (OR=0.73, 95% CI: 0.58-0.91, P=0.004); and failure in the management of HFBG (OR=2.24, 95% CI: 1.66-3.03, P<0.001). Morbidly obese patients faced worse management for HBP and HFBG, and better management for HBC. It would be interesting to integrate alarm systems to avoid this problem.

Healthcare systems are challenged by steady increases in the number of patients who are overweight and obese. Large-scale, evidence-based behavioral approaches for addressing overweight and obesity have been successfully implemented in systems such as the Veterans Health Administration (VHA). These population-based interventions target reduction in risk for obesity-associated conditions through lifestyle change and weight loss, and are associated with modest weight loss. Despite the fact that VHA has increased the overall reach of these behavioral interventions, the number of high-risk overweight and obese patients continues to rise. Recommendations for weight loss medications and bariatric surgery are included in clinical practice guidelines for the management of overweight and obesity, but these interventions are underutilized. During a recent state of the art conference on weight management held by VHA, subject matter experts identified challenges and gaps, as well as potential solutions and overarching policy recommendations, for implementing an integrated system-wide approach for improving population-based weight management.

Objective This study aims at assessing the status of obesity management in the European region and identifying future goals and objectives of professionals working in the field of obesity. Methods Presidents of all 31 EASO-affiliated (EASO = European Association for the Study of Obesity) national associations for the study of obesity were asked to invite 5 obesity experts from their country to participate in a survey. A total of 74 obesity professionals out of 23 countries participated. Questions addressed the development of guidelines, the status of obesity management, and goals and objectives for the future in obesity management. Further, EASO's three vice-presidents participated in in-depth, semi-structured interviews, in which they were asked to provide their reflection on the survey data. Results Most countries define obesity as a clinical and chronic disease, but various differences in obesity management standards exist across Europe. Existing guidelines mainly focus on the acute treatment of obesity rather than on long-term approaches. Conclusion Multidisciplinary approaches for obesity management and the collaboration between general practitioners and hospitals as well as between professionals at the local level and networks of obesity management centers need to be improved across Europe. Good practices and evidence are available. PMID:27553443

Obesity is recognised as a global epidemic and the most prevalent metabolic disease world-wide. Specialised obesity services, however, are not widely available in Europe, and obesity care can vary enormously across European regions. The European Association for the Study of Obesity (EASO, www.easo.org) has developed these criteria to form a pan-European network of accredited EASO-Collaborating Centres for Obesity Management (EASO-COMs) in accordance with accepted European and academic guidelines. This network will include university, public and private clinics and will ensure that the obese and overweight patient is managed by a holistic team of specialists and receives comprehensive state-ofthe-art clinical care. Furthermore, the participating centres, under the umbrella of EASO, will work closely for quality control, data collection, and analysis as well as for education and research for the advancement of obesity care and obesity science.

Pharmacotherapy in the Management of Pediatric Obesity.
Kelly, Aaron S; Fox, Claudia K
2017-08-01
This review provides a rationale for the use of pharmacotherapy in pediatric weight management, summarizes results of some of the key pediatric clinical trials of approved and "off-label" obesity medications, introduces new options in the pediatric pipeline, and offers a glimpse into the future of pediatric obesity medicine. Despite the need for adjunctive treatments to enhance the outcomes of lifestyle modification therapy among youth with obesity, none of the obesity medications evaluated to date have been shown to meaningfully reduce BMI or cardiometabolic risk factors. Promising medications recently approved for the treatment of obesity in adults will soon be tested in pediatric trials, offering hope that new therapeutic options will soon be available. As new medications are approved to treat pediatric obesity, it will be important to evaluate the safety and efficacy of combination pharmacotherapy and investigate predictors of response. Application of precision medicine approaches to the field of pediatric obesity management will improve the long-term outlook for the tens of millions of youth afflicted with this serious and recalcitrant disease.
Management of obesity in adult Asian Indians.
Behl, S; Misra, A
The prevalence of obesity in India is increasing and ranges from 8% to 38% in rural and 13% to 50% in urban areas. Obesity is a risk factor for development of type 2 diabetes mellitus (T2DM), hypertension, dyslipidemia, coronary heart disease and many cancers. In Asian Indians excess abdominal and hepatic fat is associated with increased risk for T2DM and cardiovascular disease. There is higher risk for development of obesity related non-communicable diseases at lower body mass index levels, compared to white Caucasians. Despite being a commonly encountered medical problem, obesity poses challenges in treatment. Many Indian physicians find themselves to be lacking time and expertise to prepare an appropriate obesity management plan and patients experience continuous weight gain over time despite being under regular medical supervision. In this article, we outline approaches to obesity management in 'real life mode' and in context to Asian Indian patients. Copyright © 2017 Cardiological Society of India. Published by Elsevier B.V.

Nutritional Approaches for Managing Obesity-Associated Metabolic Diseases
Botchlett, Rachel; Woo, Shih-Lung; Liu, Mengyang; Pei, Ya; Guo, Xin; Li, Honggui; Wu, Chaodong
2017-01-01
Obesity is an ongoing pandemic and serves as a causal factor of a wide spectrum of metabolic diseases including diabetes, fatty liver disease, and cardiovascular disease. Much evidence has demonstrated that nutrient overload/overnutrition initiates or exacerbates inflammatory responses in tissues/organs involved in the regulation of systemic metabolic homeostasis. This obesity-associated inflammation is usually at a low-grade and viewed as metabolic inflammation. When it exists continuously, inflammation inappropriately alters metabolic pathways and impairs insulin signaling cascades in peripheral tissues/organs such as adipose tissue, the liver and skeletal muscle, resulting in local fat deposition and insulin resistance and systemic metabolic dysregulation. In addition, inflammatory mediators, e.g., proinflammatory cytokines, and excessive nutrients, e.g., glucose and fatty acids, act together to aggravate local insulin resistance and form a vicious cycle to further disturb local metabolic pathways and exacerbate systemic metabolic dysregulation. Owing to the critical role of nutrient metabolism in the control of the initiation and progression of inflammation and insulin resistance, nutritional approaches have been implicated as effective tools for managing obesity and obesity-associated metabolic diseases. Based on the mounting evidence generated from both basic and clinical research, nutritional approaches are commonly used for suppressing inflammation, improving insulin sensitivity, and/or decreasing fat deposition. Consequently, the combined effects are responsible for improvement of systemic insulin sensitivity and metabolic homeostasis. PMID:28400405
Current concepts in the pharmacological management of obesity.
Carek, P J; Dickerson, L M
1999-06-01
The pharmacological management of obesity has gained increasing attention as new weight loss treatments are approved and a significant proportion of the public strives to lose weight. Obesity is associated with a high mortality rate, multiple chronic medical conditions, and carries an enormous financial burden. Obesity is a multifactorial condition, most often due to an imbalance in energy intake and expenditure. Despite the greater focus on management of obesity, weight loss remains a difficult goal to achieve. Obesity is a chronic medical condition that may require long term treatment, therefore the risks and benefits of all pharmacological agents must be carefully considered. Noradrenergic appetite suppressants (ie. phenyl-propanolamine, phentermine) result in weight loss but stimulatory effects limit their use. The serotonergic agents (fenfluramine, dexfenfluramine) were effective weight loss drugs, but were voluntarily withdrawn from the US market last year because of cardiovascular and pulmonary complications. The combination noradrenergic/serotonergic agent sibutramine is indicated for the management of obesity, particularly in the presence of other cardiovascular risk factors. Modest weight loss is achieved with sibutramine, although weight gain is significant after discontinuation. In addition, long term safety data are not yet available. The thermogenic combination of ephedrine plus caffeine is minimally effective, and adverse effects are usually transient. Other thermogenic agents, such as beta3-agonists, are still under investigation. Agents may alter digestion through lipase inhibition (orlistat) or fat substitution (olestra). Orlistat decreases systemic absorption of dietary fat, decreasing body weight and cholesterol. Olestra is a fat substitute that has been incorporated into snack foods. Olestra substitution for dietary fat has not been studied as a weight loss strategy, although olestra has no caloric value and may be beneficial. The use of
Changing the endpoints for determining effective obesity management.
Ross, Robert; Blair, Steve; de Lannoy, Louise; Després, Jean-Pierre; Lavie, Carl J
2015-01-01
Health authorities worldwide recommend weight loss as a primary endpoint for effective obesity management. Despite a growing public awareness of the importance of weight loss and the spending of billions of dollars by Americans in attempts to lose weight, obesity prevalence continues to rise. In this report we argue that effective obesity management in today's environment will require a shift in focus from weight loss as the primary endpoint, to improvements in the causal behaviors; diet and exercise/physical activity (PA). We reason that increases in PA combined with a balanced diet are associated with improvement in many of the intermediate risk factors including cardiorespiratory fitness (CRF) associated with obesity despite minimal or no weight loss. Consistent with this notion, we suggest that a focus on healthy behaviors for the prevention of additional weight gain may be an effective way of managing obesity in the short term.

Practical perspectives on the management of overweight and obesity.
Gregory, Robert S; Handelsman, Yehuda; Pezalla, Edmund J; Pikelny, Dan
2014-03-01
The prevalence of obesity, defined as a body mass index of 30 or more, has reached epidemic proportions in the United States. Obesity is associated with an increased risk of multiple conditions, including type 2 diabetes mellitus, cardiovascular disease, arthritis, and sleep apnea. To discuss issues related to obesity in the workplace, healthcare, and managed care settings, stakeholders from these areas participated in a roundtable discussion on several topics, including the management of obesity, managed care coverage policies for obesity treatments, and potential strategies for improving patient outcomes. Participants agreed that obesity is a challenging condition to treat. Lifestyle modification, one of the most commonly recommended treatment modalities, is often inadequate on its own, as patients are unable to maintain weight loss over time. Although lifestyle modification remains important, additional tools are needed. In patients who undergo bariatric surgery, lifestyle modification is also necessary for long-term weight maintenance; however, surgery is not appropriate for all patients. Pharmacologic treatment may also be considered, but cost and managed care coverage policies have the potential to limit patient access to this treatment modality. Increased awareness and additional efforts on the part of all stakeholders are needed to improve outcomes for patients affected by obesity.

To better understand obesity, its related conditions and risk factors, and the best assessment and management approaches for the adult population, the Disease Management Association of America and the National Committee for Quality Assurance partnered to conduct a literature review that could inform future initiatives of both organizations as well as others. The goals of the literature review were to: (1) describe the prevalence of obesity and related conditions and their health and financial impacts; (2) illustrate the clinical importance and interrelatedness of the conditions; and, the focus of this article, (3) describe the evidence supporting the different assessment and management options for obesity and comorbid conditions.
Role of Obesity in Asthma: Mechanisms and Management Strategies.
Scott, Hayley A; Wood, Lisa G; Gibson, Peter G
2017-08-01
Obesity is a commonly reported comorbidity in asthma, particularly in severe asthma. Obese asthmatics are highly symptomatic with a poor quality of life, despite using high-dose inhaled corticosteroids. While the clinical manifestations have been documented, the aetiologies of obese-asthma remain unclear. Several potential mechanisms have been proposed, including poor diet quality, physical inactivity and consequent accrual of excess adipose tissue. Each of these factors independently activates inflammatory pathways, potentially exerting effects in the airways. Because the origins of obesity are multifactorial, it is now believed there are multiple obese-asthma phenotypes, with varied aetiologies and clinical consequences. In this review, we will describe the clinical implications of obesity in people with asthma, our current understanding of the mechanisms driving this association and describe recently proposed obese-asthma phenotypes. We will then discuss how asthma management is complicated by obesity, and provide graded recommendations for the management of obesity in this population.
Adult obesity management in primary care, 2008-2013.
Fitzpatrick, Stephanie L; Stevens, Victor J
2017-06-01
In the U.S., the occurrence of weight counseling in primary care for patients with obesity decreased by 10% between 1995-1996 and 2007-2008. There have been several national recommendations and policies to improve obesity management since 2008. The purpose of this study was to examine the rates of body mass index (BMI) screening, obesity diagnosis, and weight management counseling in the U.S. from 2008 to 2013. The National Ambulatory Medical Care Survey visit-level data for adults 18 and over with a primary care visit during survey years 2008-2009, 2010-2011, and 2012-2013 was included in the analyses using SAS v9.3. Study outcomes included percent of visits with: BMI screening; obesity diagnosis; and weight counseling. We compared survey years on these outcomes using 2008-2009 as the reference as well as examined patient and practice-level predictors. Analyses were conducted from 2015 to early 2017. Of the total 55,608 adult primary care visits sampled, 14,143 visits (25%) were with patients with obesity. BMI screening significantly increased between 2008-2009 and 2012-2013 from 54% to 73% (OR=1.75, 95% CI 1.28-2.41); however, percent of visits with an obesity diagnosis remained low at <30%. Weight management counseling during visits significantly declined from 33% to 21% between 2008-2009 and 2012-2013 (OR=0.62, 95% CI 0.41-0.92). Despite emerging recommendations and policies, from 2008 to 2013, obesity management in primary care remained suboptimal. Identifying practical strategies to enforce policies and implement evidence-based behavioral treatment in primary care should be a high priority in healthcare reform. Copyright © 2017 Elsevier Inc.

Obesity has become a truly global epidemic, affecting all age groups, all populations, and countries of all income levels. To date, existing policies and interventions have not reversed these trends, suggesting that innovative approaches are needed to transform obesity prevention and control. There are a number of indications that the obesity epidemic is a systems problem, as opposed to a simple problem with a linear cause-and-effect relationship. What may be needed to successfully address obesity is an approach that considers the entire system when making any important decision, observation, or change. A systems approach to obesity prevention and control has many benefits, including the potential to further understand indirect effects or to test policies virtually before implementing them in the real world. Discussed here are 5 key efforts to implement a systems approach for obesity prevention: 1) utilize more global approaches; 2) bring new experts from disciplines that do not traditionally work with obesity to share experiences and ideas with obesity experts; 3) utilize systems methods, such as systems mapping and modeling; 4) modify and combine traditional approaches to achieve a stronger systems orientation; and 5) bridge existing gaps between research, education, policy, and action. This article also provides an example of how a systems approach has been used to convene a multidisciplinary team and conduct systems mapping and modeling as part of an obesity prevention program in Baltimore, Maryland.

Pediatric obesity has become increasingly prevalent over recent decades. In view of the psychosocial and physical health risks, and the high likelihood that children with obesity will grow to become adults with obesity, there is a clear need to develop evidence-based interventions that can be delivered in the health care system to optimize the health and well-being of children with obesity and their families. The aim of this paper is to describe the development, implementation, and planned evaluation of a parent-based weight management intervention designed for parents of 8-12 year olds with obesity. The principles of Intervention Mapping (IM) were used to develop an intervention called Parents as Agents of Change (PAC © ). From 2006 to 2009, an environmental scan plus qualitative (individual interviews with parents and children), quantitative (medical record reviews), and literature review data were collected to gain broad insight into family factors related to pediatric obesity and its management. Theoretical frameworks and empirical evidence guided curriculum development, which was founded primarily on the tenets of family systems theory and cognitive behavioral theory. PAC was developed as a manualized, 16-session, group-based, health care professional-led intervention for parents to address individual, family, and environmental factors related to the management of pediatric obesity. The intervention was refined based on feedback from local and international experts, and has been implemented successfully in a multi-disciplinary weight management centre in a children's hospital. IM provided a practical framework to guide the systematic development of a pediatric weight management intervention for parents of children with obesity. This logical, step-by-step process blends theory and practice and is broadly applicable in the context of obesity management intervention development and evaluation. Following intervention development, the PAC intervention was

Perioperative management of the severely obese patient: a selective pathophysiological review.
Cullen, Aidan; Ferguson, Andrew
2012-10-01
Obesity is widespread, yet it is often understood primarily as a disorder of body structure. This article provides anesthesiologists with a synopsis of recent research into the complex pathophysiology of obesity. It emphasizes the importance of this information for the perioperative planning and management of this patient group and for reviewing some of the major perioperative challenges. Obesity is a multisystem chronic pro-inflammatory disorder associated with increased morbidity and mortality. Adipocytes are far more than storage vessels for lipids. They secrete a large number of physiologically active substances called adipokines that lead to inflammation, vascular and cardiac remodelling, airway inflammation, and altered microvascular flow patterns. They contribute to linked abnormalities, such as insulin resistance and the metabolic syndrome, and they attract and activate inflammatory cells such as macrophages. These changes can lead ultimately to organ dysfunction, especially cardiovascular and pulmonary issues. In the respiratory system, anesthesiologists should be familiar not just with screening tools for obstructive sleep apnea but also with obesity hypoventilation syndrome, which is less well appreciated and carries a significant outcome disadvantage. Perioperative management is challenging. It is centred around cardiorespiratory and metabolic optimization, minimizing adverse effects of both pain and systemic opioids, effective use of regional anesthesia, and an emphasis on mobilization and nutrition - given the prevalence of micronutrient deficiencies in the severely obese. There is a risk of incorrect drug dosing in obesity, which requires an understanding of the appropriate dosing weights for perioperative medications. The literature clearly highlights the complexity of severe obesity as a multisystem disease, and anesthesiologists caring for these patients perioperatively must have a sound understanding of the changes in order to offer the highest

Obesity is a complex public health issue. Recent data indicate the increasing prevalence and severity of obesity in children. Severe obesity is a real chronic condition for the difficulties of long-term clinical treatment, the high drop-out rate, the large burden of health and psychological problems and the high probability of persistence in adulthood. A staged approach for weight management is recommended. The establishment of permanent healthy lifestyle habits aimed at healthy eating, increasing physical activity and reducing sedentary behavior is the first outcome, because of the long-term health benefits of these behaviors. Improvement in medical conditions is also an important sign of long-term health benefits. Rapid weight loss is not pursued, for the implications on growth ad pubertal development and the risk of inducing eating disorders. Children and adolescents with severe obesity should be referred to a pediatric weight management center that has access to a multidisciplinary team with expertise in childhood obesity. This article provides pediatricians a comprehensive and evidence based update on treatment recommendations of severe obesity in children and adolescents.
Health Behavior Change for Obesity Management
Teixeira, Pedro J.; Marques, Marta M.
2018-01-01
Health behavior change is central in obesity management. Due to its complexity, there has been a growing body of research on: i) the factors that predict the adoption and maintenance of health behaviors, ii) the development and testing of theories that conceptualize relationships among these factors and with health behaviors, and iii) how these factors can be implemented in effective behavior change interventions, considering characteristics of the content (techniques) and delivery. This short review provides an overview of advances in behavior change science theories and methods, focusing on obesity management, and includes a discussion of the main challenges imposed by this research field.

Pharmacological management of obesity in pediatric patients.
Boland, Cassie L; Harris, John Brock; Harris, Kira B
2015-02-01
To review current evidence of pharmacological options for managing pediatric obesity and provide potential areas for future research. A MEDLINE search (1966 to October 2014) was conducted using the following keywords: exenatide, liraglutide, lorcaserin, metformin, obesity, orlistat, pediatric, phentermine, pramlintide, topiramate, weight loss, and zonisamide. Identified articles were evaluated for inclusion, with priority given to randomized controlled trials with orlistat, metformin, glucagon-like peptide-1 agonists, topiramate, and zonisamide in human subjects and articles written in English. References were also reviewed for additional trials. Whereas lifestyle modification is considered first-line therapy for obese pediatric patients, severe obesity may benefit from pharmacotherapy. Orlistat is the only Food and Drug Administration (FDA)-approved medication for pediatric obesity and reduced body mass index (BMI) by 0.5 to 4 kg/m(2), but gastrointestinal (GI) adverse effects may limit use. Metformin has demonstrated BMI reductions of 0.17 to 1.8 kg/m(2), with mild GI adverse effects usually managed with dose titration. Exenatide reduced BMI by 1.1 to 1.7 kg/m(2) and was well-tolerated with mostly transient or mild GI adverse effects. Topiramate and zonisamide reduced weight when used in the treatment of epilepsy. Future studies should examine efficacy and safety of pharmacological agents in addition to lifestyle modifications for pediatric obesity. Lifestyle interventions remain the treatment of choice in pediatric obesity, but concomitant pharmacotherapy may be beneficial in some patients. Orlistat should be considered as second-line therapy for pediatric obesity. Evidence suggests that other diabetes and antiepileptic medications may also provide weight-loss benefits, but safety should be further evaluated. © The Author(s) 2014.
The use of lorcaserin in the management of obesity: a critical appraisal
Bai, Bo; Wang, Yu
2011-01-01
Obesity is a chronic disease with a high prevalence in both developed and developing countries. Effective management of this worldwide epidemic will have a significant impact on the health care system globally. Lifestyle interventions, such as restricting calorie consumption and increasing physical activity, remain a major component of weight-reduction programs. The development of pharmacotherapy for the management of obesity is still at the infancy stage. Side effects have been the key issue for anti-obesity drugs previously withdrawn from the market. The focus of this review, lorcaserin, is a selective serotonin receptor agonist that is currently undergoing Phase III evaluations. The efficacy of this drug in reducing body weight and improving metabolic parameters of obese patients has been demonstrated in two recent clinical trials. The available evidence indicates that this drug does not show unwanted effects on heart valves or pulmonary artery pressure, and the treatment improves the risk factors for type 2 diabetes and cardiovascular diseases. Despite these promising results, additional experimental and clinical studies are critical for the approval of lorcaserin as a new anti-obesity monodrug therapy by the US Food and Drug Administration.

Managing overweight and obesity in adults to reduce cardiovascular disease risk.
Ebbert, Jon O; Elrashidi, Muhamad Y; Jensen, Michael D
2014-10-01
Obesity is a leading preventable cause of death and disability worldwide. Obesity increases the risk for clinically identifiable risk factors for cardiovascular disease (CVD) as well as a host of other metabolic, sleep, and orthopedic disorders. Coordinated and systematic interventions are needed to manage obesity and reduce these risks. The Obesity 2 Expert Panel updated the previous guidelines and produced the "Guideline for the Management of Overweight and Obesity in Adults." The Panel used data from publications from years 1999 to 2011 to address five critical questions, provide evidence statements, and recommend creation of a treatment algorithm to guide decision making about clinical care. The current review discusses the evidence statements pertaining to CVD risk in the assessment and management of patients who are overweight and obese. We summarize the FDA-approved medications for the treatment of overweight and obesity and their impact on CVD risk and risk factors, as well as ongoing clinical trials which will further inform clinical practice.
Dietitians' views of overweight and obese people and reported management practices.
Harvey, E L; Summerbell, C D; Kirk, S F L; Hill, A J
2002-10-01
To examine dietitians' views of overweight and obese people, to explore the role of level of severity on these perceptions (overweight vs. obesity), and to explore the relationship between dietitians' views and their reported weight management practices. An independent measures survey, questioning dietitians about either overweight or obese people. One-hundred and eighty-seven members of the British Dietetic Association. A questionnaire exploring beliefs about the causes, attitudes, perceptions of responsibility and reported weight management practices. Physical inactivity was identified as an important causative factor for both overweight and obesity. Mood, eating too much of the wrong foods, repeated dieting and interpersonal factors were also seen as relatively important for both groups. Attitudes were mixed, but were generally neutral to positive. The most negative attitudes were described in terms of perceived reduced self-esteem, sexual attractiveness and health. Dietitians rated obese people more negatively than overweight people. They viewed both overweight and obese people as being responsible for their excess weight. They also reported very similar management practices for overweight and obese people. Beliefs about the causes of overweight explained more of the variance in practice than dietitians' attitudes towards or perceived responsibility of overweight and obese people. However, these associations were not consistent and strong, and other factors not investigated here are likely to have a greater influence on weight management practices.
Effects of an obesity management mentoring program for Korean children.
Lee, Gyu-Young; Choi, Yun-Jung
2016-08-01
This research aimed to develop and test a mentored obesity management program guiding physical exercise, improving eating habits, and promoting self-esteem among elementary school learners. A nonequivalent control group pretest-posttest design was used. Thirty learners were recruited through convenience sampling from two elementary schools, then evenly assigned to the experimental and control groups. Six nursing students were mentored, receiving 16h of mentorship training. A 10-week mentored obesity management program promoting physical exercise and proper nutrition was developed and provided. The two groups' pretest and posttest body mass index and self-esteem differences were statistically significant. Most participants were satisfied with the program, endorsing its provision in the regular school curriculum. A mentored obesity management program for elementary school learners would effectively manage weight and improve self-esteem. Programs purportedly curtailing childhood obesity should be expanded, and school policies regulated to enable implementation. Copyright © 2016 Elsevier Inc. All rights reserved.
Assessment of obese children and adolescents: a survey of pediatric obesity-management programs.
Eisenmann, Joey C
2011-09-01
This article provides descriptive information on the assessments conducted in stage 3 or 4 pediatric obesity-management programs associated with National Association of Children's Hospital and Related Institutions hospitals enrolled in FOCUS on a Fitter Future. Eighteen institutions completed a survey that considered the following assessments: patient/family medical history; physical examination; blood pressure; body size and composition; blood chemistry; aerobic fitness; resting metabolic rate; muscle strength and flexibility; gross motor function; spirometry; sedentary behavior and physical activity; dietary behavior and nutrition; and psychological assessments. Frequency distributions were determined for each question. Overall, the results indicate that most programs that participated in this survey were following 2007 Expert Committee assessment recommendations; however, a variety of measurement tools were used. The variation in assessment tools, protocols, etc is partially caused by the program diversity dictated by personnel, both in terms of number and duties. It also shows the challenges in standardizing methodologies across clinics if we hope to establish a national registry for pediatric obesity clinics. In addition to providing a better understanding of the current assessment practices in pediatric obesity-management programs, the results provided herein should assist other clinics/hospitals that are developing pediatric obesity programs.
Obesity Treatment in the UK Health System.
Capehorn, Matthew S; Haslam, David W; Welbourn, Richard
2016-09-01
In the UK, as in most other countries in the world, levels of obesity are increasing. According to the Kinsey report, obesity has the second largest public health impact after smoking, and it is inextricably linked to physical inactivity. Since the UK Health and Social Care Act reforms of 2012, there has been a significant restructuring of the National Health Service (NHS). As a consequence, NHS England and the Department of Health have issued new policy guidelines regarding the commissioning of obesity treatment. A 4-tier model of care is now widely accepted and ranges from primary activity, through community weight management and specialist weight management for severe and complex obesity, to bariatric surgery. However, although there are clear care pathways and clinical guidelines for evidence-based practice, there remains no single stakeholder willing to take overall responsibility for obesity care. There is a lack of provision of adequate services characterised by a noticeable 'postcode lottery', and little political will to change the obesogenic environment.
Phentermine and topiramate for the management of obesity: a review
Cosentino, Gina; Conrad, Ariane O; Uwaifo, Gabriel I
2013-01-01
Obesity is now a major public health concern worldwide with increasing prevalence and a growing list of comorbidities and complications. The morbidity, mortality and reduced productivity associated with obesity and its complications result in a major burden to health care costs. Obesity is a complex chronic medical syndrome often with multiple different etiologic factors in individual patients. The long term successful management of obesity remains particularly challenging and invariably requires a multifaceted approach including lifestyle and behavioral modification, increased physical activity, and adjunctive pharmacotherapy. Bariatric surgery remains a last resort though at present it has the best results for achieving sustained robust weight loss. Obesity pharmacotherapy has been very limited in its role for long term obesity management because of the past history of several failed agents as well as the fact that presently available agents are few, and generally utilized as monotherapy. The recent FDA approval of the fixed drug combination of phentermine and extended release topiramate (topiramate-ER) (trade name Qsymia™) marks the first FDA approved combination pharmacotherapeutic agent for obesity since the Phen-Fen combination of the 1990s. This review details the history and clinical trial basis for the use of both phentermine and topiramate in obesity therapeutics as well as the results of clinical trials of their combination for obesity treatment in humans. The initial clinical approval trials offer evidence that this fixed drug combination offers synergistic potential for effective, robust and sustained weight loss with mean weight loss of at least 10% of baseline achieved and sustained for up to 2 years in over 50% of subjects treated. It is anticipated that this agent will be the first in a new trend of multi-agent combination therapy for the chronic adjunctive management of obesity. PMID:23630412
An obesity/cardiometabolic risk reduction disease management program: a population-based approach.
Villagra, Victor G
2009-04-01
Obesity is a critical health concern that has captured the attention of public and private healthcare payers who are interested in controlling costs and mitigating the long-term economic consequences of the obesity epidemic. Population-based approaches to obesity management have been proposed that take advantage of a chronic care model (CCM), including patient self-care, the use of community-based resources, and the realization of care continuity through ongoing communications with patients, information technology, and public policy changes. Payer-sponsored disease management programs represent an important conduit to delivering population-based care founded on similar CCM concepts. Disease management is founded on population-based disease identification, evidence-based care protocols, and collaborative practices between clinicians. While substantial clinician training, technology infrastructure commitments, and financial support at the payer level will be needed for the success of disease management programs in obesity and cardiometabolic risk reduction, these barriers can be overcome with the proper commitment. Disease management programs represent an important tool to combat the growing societal risks of overweight and obesity.
The role of endoscopic therapy in obesity management: intragastric balloons and aspiration therapy
Kumar, Nitin; Sullivan, Shelby; Thompson, Christopher C
2017-01-01
Weight management is increasingly incorporating endoscopic bariatric therapy (EBT). As the global burden of obesity and its comorbidities has increased, it is evident that novel therapeutic approaches will be necessary to address the obesity epidemic. EBTs offer greater efficacy than diet and lifestyle modification and lower invasiveness than bariatric surgery. The US Food and Drug Administration has approved two intragastric balloons and aspiration therapy for the treatment of obesity: Apollo Orbera is indicated for the treatment of Class I and Class II obesity, Re Shape Integrated Dual Balloon system is indicated for the same range with a comorbidity, and Aspire Bariatrics AspireAssist is approved for patients with a body mass index of 35–55 kg/m2. These devices have proven safe and effective in clinical trials and are gaining commercial acceptance in the USA; the Orbera has been used extensively outside the USA for over 20 years. These devices will need to be delivered in the context of a multidisciplinary weight loss program, integrating comprehensive care of obesity. Patient selection is important, and ensuring appropriate patient expectations and understanding of alternatives such as pharmacologic therapy and surgery is essential. With several EBTs on the horizon, patients with obesity will have an even broader array of safe and effective options for weight management in the future. PMID:28740414

[Options for stress management in obesity treatment].
Czeglédi, Edit
2016-02-14
Overeating and physical inactivity are of great importance in the etiology of obesity. Psychological factors are often found in the background of life style. Chronic stress can contribute to physical inactivity and behaviors that hinder the keeping of a diet (e.g., irregular eating pattern, emotional eating). Results of randomized controlled trials show that relaxation can reduce emotional eating, improve cognitive restraint, and thereby reduce weight. However, stress management is more than relaxation. It consists of adaptive emotion-focused and problem-focused coping strategies and skills to improve relationships. Deflection skills may help in replacing emotional eating with other behaviors. Cognitive restructuring, saying no, and problem solving help to prevent or manage conflicts and difficulties otherwise would result in overeating due to distress. Developing stress management skills may result in greater compliance with the treatment. The techniques presented in the study can be easily applied by general practitioners or specialists, and provide tools for optimizing obesity treatment.

Obesity counselling in primary care is positively associated with self-reported behaviour change in patients with obesity. Obesity counselling is rare, and when it does occur, it is often of low quality because of poor training and/or competency of providers' obesity management, lack of time and economical disincentives, and negative attitude towards obesity and obesity management. 5As frameworks are routinely used for behaviour-change counselling and addiction management (e.g. smoking cessation), but few studies have examined its efficacy for weight management. This study presents pilot data from the implementation and evaluation of an obesity management tool (5As of Obesity Management developed by the Canadian Obesity Network) in a primary care setting. Results show that the tool facilitates weight management in primary care by promoting physician-patient communications, medical assessments for obesity and plans for follow-up care. Obesity remains poorly managed in primary care. The 5As of Obesity Management is a theory-driven, evidence-based minimal intervention designed to facilitate obesity counselling and management by primary care practitioners. This project tested the impact of implementing this tool in primary care clinics. Electronic self-administered surveys were completed by pre-screened obese subjects at the end of their appointments in four primary care clinics (over 25 healthcare providers [HCPs]). These measurements were performed before (baseline, n = 51) and 1 month after implementing the 5As of Obesity Management (post-intervention, n = 51). Intervention consisted of one online training session (90 min) and distribution of the 5As toolkit to HCPs of participating clinics. Subjects completing the survey before and after the intervention were comparable in terms of age, sex, body mass index, comorbidities, satisfaction and self-reported health status (P > 0.2). Implementing the 5As of Obesity Management resulted in a twofold increase

Adulthood and childhood obesity is rapidly becoming an epidemic problem and it has a short and long-term impact on health. Short-term consequences are mostly represented by psychological effects; in fact obese children have more chances to develop psychological or psychiatric problems than non-obese children. The main long-term effect is represented by the fact that childhood obesity continues into adulthood obesity and this results in negative effects in young adult life, since obesity increases the risk to develop morbidity and premature mortality. The obesity-related diseases are mostly represented by hypertension, type 2 diabetes, dyslipidemia, cardiovascular diseases. Medical treatment should be discouraged in childhood because of the side effects and it should be only reserved for obese children with related medical complications. Lifestyle changes should be encouraged in both adulthood and childhood obesity. This review focuses on the management of obesity both in adulthood and in childhood, paying particular attention to lifestyle changes that should be recommended.

Search included terms such as "obesity," "overweight," "weight loss," "comorbidity," "diabetes," cardiovascular," "cancer," "depression," "management," and "intervention." Over one third of U.S. adults have obesity. Obesity is associated with a range of comorbidities, including diabetes, cardiovascular disease, obstructive sleep apnea, and cancer; however, modest weight loss in the 5%-10% range, and above, can significantly improve health-related outcomes. Many individuals struggle to maintain weight loss, although strategies such as realistic goal-setting and increased consultation frequency can greatly improve the success of weight-management programs. Nurse practitioners have key roles in establishing weight-loss targets, providing motivation and support, and implementing weight-loss programs. With their in-depth understanding of the research in the field of obesity and weight management, nurse practitioners are well placed to effect meaningful changes in weight-management strategies deployed in clinical practice. ©2017 American Association of Nurse Practitioners.

Nearly two thirds of the US population is overweight or obese and those numbers are climbing. Many organizations are beginning to recognize overweight and obesity as severe health threats and to acknowledge that treatment can serve as an important first step in addressing this epidemic. Through its Obesity with Co-morbidities Initiative, the Disease Management Association of America (DMAA) seeks to raise awareness and improve understanding of the role disease management (DM) can play in the treatment and management of obesity with comorbidities. Among the objectives of the Obesity with Co-morbidities Initiative was to develop standard definitions of obesity and obesity with comorbidities and to conduct qualitative research among key DM stakeholders. The first project undertaken and completed by the Obesity with Associated Co-morbidities Steering Committee and work group was to define the term "obesity" for consistent usage within the DM community for the purposes of population-based interventions. As part of this initiative, DMAA partnered with Synovate, a global market research firm, to conduct focus groups and in-depth interviews in order to collect qualitative data on attitudes and practices related to obesity treatment and coverage among key industry stakeholders, including health plans, disease management organizations, employers, and the business community. The findings indicated that obesity was widely recognized as a serious issue, but there remained varying opinions regarding responsibility, health and productivity costs, coverage, and best treatment methods among the participants. DMAA will continue this initiative through 2007 and will continue to develop a knowledge base of obesity guidelines and management practices, create valuable tools and resources including an online resource center, and facilitate partnerships with other organizations involved in the management and prevention of obesity.
Perceptions of factors associated with weight management in obese adults with schizophrenia.
Lundgren, Jennifer D; Rempfer, Melisa V; Lent, Michelle R; Foster, Gary D
2014-12-01
Individuals with serious mental illnesses are at increased risk of obesity, although the behavioral factors contributing to excess weight are not well understood. We report on the eating behavior, physical activity, and body image of obese adults with and without schizophrenia spectrum disorders. Twenty-two obese adults diagnosed with schizophrenia or schizoaffective disorder were compared to demographically matched obese adults without psychiatric diagnoses on their responses to a comprehensive assessment of several psychosocial and behavioral domains relevant to obesity and weight management. The schizophrenia group, compared to controls, reported more difficulty with several eating behaviors that were self-identified as contributing to increased weight. They also reported more enjoyment of physical activity and greater satisfaction with body weight and shape compared to controls. Clinically relevant group differences were identified that should be considered when designing ecologically valid weight management assessments and interventions for individuals diagnosed with serious mental illnesses. Health care providers are encouraged to assess an individual's weight management strengths and barriers through available assessment tools and home visits, as well as offer specific environmental and behavioral changes to manage hunger and modify eating patterns.

Childhood obesity: a systems medicine approach.
Stone, William L; Schetzina, Karen; Stuart, Charles
2016-06-01
Childhood obesity and its sequelae are a major public health problem in both the USA and globally. This review will focus on a systems medicine approach to obesity. Systems medicine is an integrative approach utilizing the vast amount of data garnered from "omics" technology and integrating these data with conventional pathophysiology as well as diverse environmental factors such as diet, exercise, community dynamics and the intestinal microbiome. Omics technology includes genomics, epigenomics, metagenomics, metabolomics and proteomics. In addition to unraveling etiology, the goals of a systems medicine approach are to provide actionable and evidenced-based clinical approaches. In the case of childhood obesity, an additional goal is characterizing measureable risk factors/biomarkers for obesity at the earliest possible age and devising age-appropriate optimal intervention strategies. It is also important to establish the age at which interventions could be critical. As discussed below, it is possible that some of the pathophysiological and epigenetic changes resulting from childhood obesity could become more irreversible the longer the obesity remains untreated.
Decisions about weight management: a synthesis of qualitative studies of obesity.
Brown, I; Gould, J
2011-04-01
There is a high non-attendance and dropout attrition from weight management interventions for adults with obesity. Patient dissatisfaction with consultations involving decisions about interventions may be a factor. A systematic review was undertaken of qualitative studies reporting perceptions, experiences, contexts and influences for adults facing, or reflecting on, weight management. The aim was to synthesize a generic model of influences on decision-making about weight management for adult patients. Electronic database and hand searches identified 29 qualitative studies involving 1387 participants (mean age 45.3 years; mean BMI 37.1 kg m(-2) ; 79.9% women). Seven overarching themes were inductively derived from extracted data spanning: cultural identity; social structures such as gender; responses to obesity stigma; previous weight loss experiences; personal motivators and barriers; social support; and practical resources. A model is presented in the paper. Improving decisions about weight management requires attention to how diffuse cultural and psycho-social factors, such as obesity stigma, influence patient choices. Reflection on experiences of previous attempts at weight loss is also essential, as are practical resource factors - particularly for less affluent groups. Considering these factors along with more established theories of individual psychological motivations and barriers may help to improve initial participation and retention within interventions. © 2011 The Authors.

Management of obesity in NIDDM (non-insulin-dependent diabetes mellitus).
Cheah, J S
1998-08-01
Obesity is common in NIDDM; in a cohort of 314 diabetics in Singapore, 44.3% are overweight. Management of obesity in diabetics differs from that in non-diabetics in that it is more urgent; weight maintenance is more difficult and hypoglycaemic medication may cause weight changes. Like in the non-diabetic, management of obesity in diabetic requires a pragmatic and realistic approach. A team approach is required: the help of the nurse educator, the dietitian, behaviour modification therapist, exercise therapist etc are required. A detailed history, careful physical examination and relevant investigations are required to assess the severity of the diabetic state and to exclude an occasional underlying cause of the obesity in the obese NIDDM. Weight loss is urgent in the obese NIDDM, especially those with android obesity. There must be a reduction in caloric intake. Weight loss leads to improvement in the glucose tolerance, insulin sensitivity, reduction in lipid levels and fall in blood pressure in the hypertensive. Exercise is of limited value except in the younger obese NIDDM. Metformin is the hypoglycaemic drug of choice as it leads to consistent weight reduction. The sulphonylureas may cause weight gain. Insulin should be avoided where possible as it causes further weight gain. Other hypoglycaemic agents include Glucobay (alpha-glucosidase inhibitor) and Troglitazone (insulin sensitizer) which do not alter the weight. Orlistat (lipase inhibitor) is promising as it causes reduction of weight, blood-glucose and lipid levels. Anti-obesity drugs (noradrenergic and serotonergic agents) have modest effects on weight reduction in the obese NIDDM; a widely use preparation, Dexfenfluramine (Adifax) has been withdrawn because of side effects. Surgery such as gastric plication is the last resort in treating the morbidly obese NIDDM. The discovery of leptin in 1994 has led to intense research into energy homeostasis in obesity; hopefully this will lead to better treatment of
Hypercortisolism in obesity-associated hypertension.
Varughese, Amy G; Nimkevych, Oksana; Uwaifo, Gabriel I
2014-07-01
Obesity is prevalent worldwide and associated with co-morbidities that result in increased cardiovascular risk. Hypertension is the most prevalent obesity comorbidity associated with increased cardiovascular risk. Obesity hypertension is a distinct subtype of essential hypertension. While endogenous Cushing's syndrome is an uncommon cause of both obesity and hypertension, the recent recognition of other hypercortisolemic states has raised the profile of hypercortisolism as an important contributor in obesity hypertension. The high prevalence of exogenous, iatrogenic, pseudo, and subclinical Cushing's syndromes makes hypercortisolism an important diagnostic consideration in the evaluation and management of patients with obesity hypertension who are resistant to conventional management. Available data suggest that the renin-angiotensin-aldosterone system modulating antihypertensives have the best efficacy in hypercortisolism-mediated obesity hypertension. Strategies aimed at reducing cortisol production and action also have utility. This review provides a comprehensive overview of the epidemiology, etiopathogenesis and management options available for glucocorticoid-mediated obesity hypertension.
Role of the family doctor in the management of adults with obesity: a scoping review

Objectives Obesity management is an important issue for the international primary care community. This scoping review examines the literature describing the role of the family doctor in managing adults with obesity. The methods were prospectively published and followed Joanna Briggs Institute methodology. Setting Primary care. Adult patients. Included papers Peer-reviewed and grey literature with the keywords obesity, primary care and family doctors. All literature published up to September 2015. 3294 non-duplicate papers were identified and 225 articles included after full-text review. Primary and secondary outcome measures Data were extracted on the family doctors’ involvement in different aspects of management, and whether whole person and person-centred care were explicitly mentioned. Results 110 papers described interventions in primary care and family doctors were always involved in diagnosing obesity and often in recruitment of participants. A clear description of the provider involved in an intervention was often lacking. It was difficult to determine if interventions took account of whole person and person-centredness. Most opinion papers and clinical overviews described an extensive role for the family doctor in management; in contrast, research on current practices depicted obesity as undermanaged by family doctors. International guidelines varied in their description of the role of the family doctor with a more extensive role suggested by guidelines from family medicine organisations. Conclusions There is a disconnect between how family doctors are involved in primary care interventions, the message in clinical overviews and opinion papers, and observed current practice of family doctors. The role of family doctors in international guidelines for obesity may reflect the strength of primary care in the originating health system. Reporting of primary care interventions could be improved by enhanced descriptions of the providers involved and explanation
Management of obesity in non- insulin- dependent diabetes mellitus.

Weight loss leads to an improvement in glucose tolerance and in insulin sensitivity, as well as to a reduction in lipid levels and to a fall in blood pressure in the hypertensive. Exercise is of limited short-term value measured in terms of weight reduction, except in the younger obese NIDDM patient; but it does allow improvement in overall metabolic control and, long-term, is critical for preferred weight maintenance. The biguanide, Metformin, is the hypoglycaemic drug of choice as it leads to consistent weight reduction. The sulphonylureas may cause weight gain.

In this review, we examine one of the ironies of American health care-that we pay more for disease management than disease prevention. Instead of preventing type 2 diabetes (T2DM) by treating its precursor, obesity, we fail to provide sufficient insurance coverage for weight management only to fund the more costly burden of overt T2DM. There is a vital need for expanded insurance coverage to help foster a weight-centric approach to T2DM management. This includes broader coverage of anti-diabetic medications with evidence of cardiovascular risk reduction and mortality benefit, anti-obesity pharmacotherapy, bariatric surgery, weight loss devices, endoscopic bariatric therapies, and lifestyle interventions for the treatment of obesity. The fundamental question to ask is why weight? Why wait to go after obesity until its end-stage sequelae cause intractable conditions? Instead of managing the complications of T2DM, consider preventing them by tackling obesity.
Management of obesity in patients with type 2 diabetes mellitus in primary care.
Mohammad, Shoaib; Ahmad, Jamal
2016-01-01
Obesity and being overweight is the most powerful risk factor accounting for 80-90% of patients with type 2 diabetes mellitus (T2DM). The epidemic of obesity is driving the diabetes epidemic to alarming levels and primary care is becoming an important setting for obesity management in T2DM in India. Yet many primary care providers feel ill-equipped or inadequately supported to address obesity in patients with diabetes. This article reviews the most recent and strongest evidence-based strategies that may aid physicians in management of obesity in patients with T2DM in primary care. A systematic literature search of MEDLINE using the search terms Obesity, Obesity in T2DM, weight loss and Primary Care was conducted. The American Diabetes Association, National Institute for Health, National Institute of Health and Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN) and World Health Organization websites were also searched. Most studies in this area are observational in design with few randomized controlled trials (RCTs). Articles and studies involving meta-analysis or RCTs were preferred over other types. Effective weight management treatment in T2DM patient can be implemented in the primary care setting. Evidence based individualized lifestyle and pharmacologic measures supported by behavioral intervention and counseling with appropriate and informed surgical referrals has the potential to improve the success of weight management within primary care.

To examine physiotherapists' perceptions of their role in the rehabilitation management of individuals with obesity. A Web-based survey was conducted in 2008. Participants were recruited through the Canadian Physiotherapy Association (CPA) via electronic communication and were eligible if they had entry level to practice qualifications and were residents of Canada. The online questionnaire consisted of 61 statements pertaining to potential PT roles, barriers, and learning needs, developed using the framework of CPA's position statement on obesity. Frequencies were computed for all Likert-scale response items on the questionnaire. A total of 851 physiotherapists, representative of CPA membership, participated in the study. There was strong agreement that physiotherapists have a role to play in the management of clients who are obese through exercise interventions (96%), mobility training (97%), and cardiorespiratory programmes for impairments associated with obesity (95%). Respondents were less clear about their role in the assessment of body fat or patients' weight loss. Lack of client motivation was identified as a barrier to treatment. Physiotherapists were clear that they see their role as largely focused on exercise and education to treat conditions associated with obesity. These are important components but do not by themselves constitute an overall management plan. Purpose: To examine physiotherapists' perceptions of their role in the rehabilitation management of individuals with obesity. Methods: A Web-based survey was conducted in 2008.

The increasing prevalence of chronic pain and obesity has significant health and cost implications for economies in the developed and developing world. Evidence suggests that there is a positive correlation between obesity and chronic pain and the link between them is thought to be systemic inflammation. The aim of this narrative review was to explore the physiological links between chronic musculoskeletal pain and obesity and to consider the potential role of regular physical activity in providing a means of managing obesity-related chronic pain. Systemic inflammation, mechanical overload, and autonomic dysfunction are associated with increased prevalence and severity of chronic pain in individuals with obesity. It has been proposed, therefore, that interventions that target systemic inflammation could help to reduce chronic pain in obese individuals. Reduction in abdominal fat has been shown to alleviate pain and reduce the systemic markers of inflammation that contribute to chronic pain. Interventions that include exercise prescription have been shown to reduce both abdominal fat and systemic inflammation. Furthermore, exercise is also known to reduce pain perception and improve mental health and quality of life that also improves pain outcomes. However, adherence to formal exercise prescription is poor and therefore exercise programmes should be tailored to the interests, needs, and abilities of individuals to reduce attrition.
Parents' views and experiences of childhood obesity management in primary care: a qualitative study.
Turner, Katrina M; Salisbury, Chris; Shield, Julian P H
2012-08-01
Primary care has been viewed as an appropriate setting for childhood obesity management. Little is known about parents' views and experiences of obesity management within this clinical setting. These views and experiences need to be explored, as they could affect treatment success. To explore parents' views and experiences of primary care as a treatment setting for childhood obesity. In-depth interviews were held with 15 parents of obese children aged 5-10 years, to explore their views and experiences of primary care childhood obesity management. Parents were contacted via a hospital-based childhood obesity clinic, general practices and Mind, Exercise, Nutrition … Do it! (MEND) groups based in Bristol, England. The interviews were audio-taped transcribed verbatim and analysed thematically. Parents viewed primary care as an appropriate setting in which to treat childhood obesity but were reluctant to consult due to a fear of being blamed for their child's weight and a concern about their child's mental well-being. They also questioned whether practitioners had the knowledge, time and resources to effectively manage childhood obesity. Parents varied in the extent to which they had found consulting a practitioner helpful, and their accounts suggested that GPs and school nurses offer different types of support. Parents need to be reassured that practitioners will address their child's weight in a non-judgemental sensitive manner and are able to treat childhood obesity effectively. A multidisciplinary team approach might benefit a child, as different practitioners may vary in the type of care they provide.
Respiratory Management of Perioperative Obese Patients.

With a rising incidence of obesity in the United States, anesthesiologists are faced with a larger volume of obese patients coming to the operating room as well as obese patients with ever-larger body mass indices (BMIs). While there are many cardiovascular and endocrine issues that clinicians must take into account when caring for the obese patient, one of the most prominent concerns of the anesthesiologist in the perioperative setting should be the status of the lung. Because the pathophysiology of reduced lung volumes in the obese patient differs from that of the ARDS patient, the best approach to keeping the obese patient's lung open and adequately ventilated during mechanical ventilation is unique. Although strong evidence and research are lacking regarding how to best ventilate the obese surgical patient, we aim with this review to provide an assessment of the small amount of research that has been conducted and the pathophysiology we believe influences the apparent results. We will provide a basic overview of the anatomy and pathophysiology of the obese respiratory system and review studies concerning pre-, intra-, and postoperative respiratory care. Our focus in this review centers on the best approach to keeping the lung recruited through the prevention of compression atelectasis and the maintaining of physiological lung volumes. We recommend the use of PEEP via noninvasive ventilation (NIV) before induction and endotracheal intubation, the use of both PEEP and periodic recruitment maneuvers during mechanical ventilation, and the use of PEEP via NIV after extubation. It is our hope that by studying the underlying mechanisms that make ventilating obese patients so difficult, future research can be better tailored to address this increasingly important challenge to the field of anesthesia.

Gastrointestinal Issues in the Assessment and Management of the Obese Patient
Hussain, Zulfiqar
2007-01-01
As the obesity epidemic spreads across the world, physicians of all specialties will be called on to participate in the management of this condition. Gastroenterologists are no exception and can expect, in the future, to play a major role in all aspects of the care of the obese patient. Thus, gastroenterologists must learn to recognize, prevent, and treat gastrointestinal disorders related to obesity, and they must have an understanding of the risks and benefits of various management strategies. Gastroenterologists may also be called upon to assist in the evaluation and management of liver and gastrointestinal problems that have developed following bariatric surgery. When treating these problems, a thorough understanding of the anatomic and physiologic perturbations associated with a given procedure is essential, as is the knowledge of which complications are linked to weight loss and which are linked to a specific surgical approach.

Physiological and management implications of obesity in critical illness.
Shashaty, Michael G S; Stapleton, Renee D
2014-10-01
Obesity is highly prevalent in the United States and is becoming increasingly common worldwide. The anatomic and physiological changes that occur in obese individuals may have an impact across the spectrum of critical illness. Obese patients may be more susceptible to hypoxemia and hypercapnia. During mechanical ventilation, elevated end-expiratory pressures may be required to improve lung compliance and to prevent ventilation-perfusion mismatch due to distal airway collapse. Several studies have shown an increased risk of organ dysfunction such as the acute respiratory distress syndrome and acute kidney injury in obese patients. Predisposition to ventricular hypertrophy and increases in blood volume should be considered in fluid management decisions. Obese patients have accelerated muscle losses in critical illness, making nutrition essential, although the optimal predictive equation to estimate nutritional needs or formulation for obese patients is not well established. Many common intensive care unit medications are not well studied in obese patients, necessitating understanding of pharmacokinetic concepts and consultation with pharmacists. Obesity is associated with higher risk of deep venous thrombosis and catheter-associated bloodstream infections, likely related to greater average catheter dwell times. Logistical issues such as blood pressure cuff sizing, ultrasound assistance for procedures, diminished quality of some imaging modalities, and capabilities of hospital equipment such as beds and lifts are important considerations. Despite the physiological alterations and logistical challenges involved, it is not clear whether obesity has an effect on mortality or long-term outcomes from critical illness. Effects may vary by type of critical illness, obesity severity, and obesity-associated comorbidities.
Management of Hypothalamic Obesity during Transition from Childhood to Adulthood.
Bretault, Marion; Carette, Claire; Barsamian, Charles; Czernichow, Sébastien
2018-01-01
Hypothalamic obesity (HO) is a rare and serious disease of various origins: tumor, traumatism, radiotherapy, vascular, genetic, or even psychotropic drug use. HO usually begins in childhood with eating disorders and progresses with an aggregate of severe comorbidities. Transition from pediatric to adult health care is a critical period to assure weight stability and a good management of comorbidities. In case of loss to follow-up, there is an increased risk of major weight gain and long-term complications with severe obesity. To minimize this risk, pediatric and adult specialists must work together to prepare, supervise, and monitor transition. Transition ideally involves the patient, parents, and care providers with a good communication between pediatric and adult teams from expert centers. Maintaining a diet and physical activity management plan, acquisition of autonomy for hormone replacement therapy and management of psychosocial consequences of obesity are fundamental issues in patients with HO. Patient associations and specialized diet center weight loss programs can help as well as group approaches. © 2018 S. Karger AG, Basel.

Hyperglycemia in pregnancy is associated with increased risk of offspring childhood obesity. Treatment reduces macrosomia; however, it is unclear if this effect translates into a reduced risk of childhood obesity. We performed a systematic review and meta-analysis of randomized controlled trials to evaluate the efficacy and safety of intensive glycemic management in pregnancy in preventing childhood obesity. We searched MEDLINE, EMBASE, CENTRAL and ClinicalTrials.gov up to February 2016 and conference abstracts from 2010 to 2015. Two reviewers independently identified randomized controlled trials evaluating intensive glycemic management interventions for hyperglycemia in pregnancy and included four of the 383 citations initially identified. Two reviewers independently extracted study data and evaluated internal validity of the studies using the Cochrane Collaboration's Risk of Bias tool. Data were pooled using random-effects models. Statistical heterogeneity was quantified using the I 2 test. The primary outcome was age- and sex-adjusted childhood obesity. Secondary outcomes included childhood weight and waist circumference and maternal hypoglycemia during the trial (safety outcome). The four eligible trials (n=767 children) similarly used lifestyle and insulin to manage gestational hyperglycemia, but only two measured offspring obesity and waist circumference and could be pooled for these outcomes. We found no association between intensive gestational glucose management and childhood obesity at 7-10 years of age (relative risk 0.89, 95% confidence interval (CI) 0.65 to 1.22; two trials; n=568 children). Waist circumference also did not differ between treatment and control arms (mean difference, -2.68 cm; 95% CI, -8.17 to 2.81 cm; two trials; n=568 children). Intensive gestational glycemic management is not associated with reduced childhood obesity in offspring, but randomized data is scarce. Long-term follow-up of trials should be prioritized and comprehensive
Weight management in Canada: an environmental scan of health services for adults with obesity
2014-01-01
Background Obesity in Canada is a growing concern, but little is known about the available services for managing obesity in adults. Our objectives were to (a) survey and describe programs dedicated to weight management and (b) evaluate program adherence to established recommendations for care. Methods We conducted an online environmental scan in 2011 to identify adult weight management services throughout Canada. We examined the degree to which programs adhered to the 2006 Canadian Clinical Practice Guidelines on the Management and Prevention of Obesity in Adults and Children (CCPGO) and the analysis criteria developed by the Association pour la Santé Publique du Québec (ASPQ). Results A total of 83 non-surgical (34 community-based, 42 primary care-based, 7 hospital-based) and 33 surgical programs were identified. All programs encouraged patient self-management. However, few non-surgical programs adhered to the CCPGO recommendations for assessment and intervention, and there was a general lack of screening for eating disorders, depression and other psychiatric diseases across all programs. Concordance with the ASPQ criteria was best among primary care-based programs, but less common in other settings with deficits most frequently revealed in multidisciplinary health assessment/management and physical activity counselling. Conclusions With more than 60% of Canadians overweight or obese, our findings highlight that availability of weight management services is far outstripped by need. Our observation that evidence-based recommendations are applied inconsistently across the country validates the need for knowledge translation of effective health services for managing obesity in adults.

Management of weight loss in obesity-associated male infertility: a spotlight on bariatric surgery.
Abiad, Firass; Awwad, Johnny; Abbas, Hussein A; Zebian, Dina; Ghazeeri, Ghina
2017-12-01
In recent years, there has been a paralleled increase between male obesity and infertility rates. Obesity is associated with impaired hypothalamic-pituitary-gonadal axis, aberrant semen parameters, and subfertility or infertility. Weight loss is strongly recommended for the management of obesity-associated infertility. Lifestyle modifications that include caloric restriction and increased physical activity have a short-lived impact. Bariatric surgery is a better and more durable weight loss alternative. Comprehensive information about the benefits of weight loss on obesity-associated male infertility following bariatric surgery is still emerging. In this review, we discuss the hormonal, physical and environmental mechanism contributing to obesity-associated infertility. We then assess weight loss approaches, which include lifestyle modification, medical and surgical approaches, that can improve fertility in obese men. This review focuses also on bariatric surgery for the management of obese men seeking fertility treatment. Anecdotal evidence suggesting that bariatric surgery can impair fertility is also discussed.
Application of virtual reality methods to obesity prevention and management research.
Persky, Susan
2011-03-01
There is a great need for empirical evidence to inform clinical prevention and management of overweight and obesity. Application of virtual reality (VR) methods to this research agenda could present considerable advantages. Use of VR methods in basic and applied obesity prevention and treatment research is currently extremely limited. However, VR has been employed for social and behavioral research in many other domains where it has demonstrated validity and utility. Advantages of VR technologies as research tools include the ability to situate hypothetical research scenarios in realistic settings, tight experimental control inherent in virtual environments, the ability to manipulate and control any and all scenario elements, and enhanced behavioral measurement opportunities. The means by which each of these features could enhance obesity prevention and management research is discussed and illustrated in the context of an example research study. Challenges associated with the application of VR methods, such as technological limitations and cost, are also considered. By employing experimental VR methods to interrogate clinical encounters and other health-related situations, researchers may be able to elucidate causal relationships, strengthen theoretical models, and identify potential targets for intervention. In so doing, researchers stand to make important contributions to evidence-based practice innovation in weight management and obesity prevention. © 2011 Diabetes Technology Society.

Health information technology to guide pediatric obesity management.
McDonald, Julia; Goldman, Roberta E; O'Brien, Ashley; Ayash, Christine; Mitchell, Kathy; Marshall, Richard; Simon, Steven R; Taveras, Elsie M
2011-06-01
The purpose of this study was to examine pediatricians' familiarity with expert committee recommendations on the management of childhood obesity and their use of health information technology for obesity-related care. The authors interviewed 35 pediatricians from 17 primary care practices using an electronic health record; immersion crystallization facilitated analysis of the qualitative data. Nearly all pediatricians were unfamiliar with expert recommendations; however, all participants reported using growth charts and providing nutrition and physical activity counseling. Most participants wanted easy access to educational materials they could print for patients. The majority of participants were in favor of an electronic alert to identify obese patients, remind clinicians of current guidelines, and facilitate ordering, believing it would help standardize care. Concerns included "alert fatigue," distraction, and disruption of workflow. Suggestions for future electronic functions included tailored educational materials and physical activity resources customized by patient address.

The epidemic of obesity continues at alarming rates, with a high burden to our economy and society. The American Gastroenterological Association understands the importance of embracing obesity as a chronic, relapsing disease and supports a multidisciplinary approach to the management of obesity. Because gastrointestinal disorders resulting from obesity are more frequent and often present sooner than type 2 diabetes mellitus and cardiovascular disease, gastroenterologists have an opportunity to address obesity and provide an effective therapy early. Patients who are overweight or obese already fill gastroenterology clinics with gastroesophageal reflux disease and its associated risks of Barrett's esophagus and esophageal cancer, gallstone disease, nonalcoholic fatty liver disease/nonalcoholic steatohepatitis, and colon cancer. Obesity is a major modifiable cause of diseases of the digestive tract that frequently goes unaddressed. As internists, specialists in digestive disorders, and endoscopists, gastroenterologists are in a unique position to play an important role in the multidisciplinary treatment of obesity. This American Gastroenterological Association paper was developed with content contribution from Society of American Gastrointestinal and Endoscopic Surgeons, The Obesity Society, Academy of Nutrition and Dietetics, and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition, endorsed with input by American Society for Gastrointestinal Endoscopy, American Society for Metabolic and Bariatric Surgery, American Association for the Study of Liver Diseases, and Obesity Medicine Association, and describes POWER: Practice Guide on Obesity and Weight Management, Education and Resources. Its objective is to provide physicians with a comprehensive, multidisciplinary process to guide and personalize innovative obesity care for safe and effective weight management.

Systems Science and Childhood Obesity: A Systematic Review and New Directions
Foster, E. Michael
2013-01-01
As a public health problem, childhood obesity operates at multiple levels, ranging from individual health behaviors to school and community characteristics to public policies. Examining obesity, particularly childhood obesity, from any single perspective is likely to fail, and systems science methods offer a possible solution. We systematically reviewed studies that examined the causes and/or consequences of obesity from a systems science perspective. The 21 included studies addressed four general areas of systems science in obesity: (1) translating interventions to a large scale, (2) the effect of obesity on other health or economic outcomes, (3) the effect of geography on obesity, and (4) the effect of social networks on obesity. In general, little research addresses obesity from a true, integrated systems science perspective, and the available research infrequently focuses on children. This shortcoming limits the ability of that research to inform public policy. However, we believe that the largely incremental approaches used in current systems science lay a foundation for future work and present a model demonstrating the system of childhood obesity. Systems science perspective and related methods are particularly promising in understanding the link between childhood obesity and adult outcomes. Systems models emphasize the evolution of agents and their interactions; such evolution is particularly salient in the context of a developing child. PMID:23710344
Systems and WBANs for Controlling Obesity
Mohammed, Maali Said; Sendra, Sandra
2018-01-01
According to World Health Organization (WHO) estimations, one out of five adults worldwide will be obese by 2025. Worldwide obesity has doubled since 1980. In fact, more than 1.9 billion adults (39%) of 18 years and older were overweight and over 600 million (13%) of these were obese in 2014. 42 million children under the age of five were overweight or obese in 2014. Obesity is a top public health problem due to its associated morbidity and mortality. This paper reviews the main techniques to measure the level of obesity and body fat percentage, and explains the complications that can carry to the individual's quality of life, longevity and the significant cost of healthcare systems. Researchers and developers are adapting the existing technology, as intelligent phones or some wearable gadgets to be used for controlling obesity. They include the promoting of healthy eating culture and adopting the physical activity lifestyle. The paper also shows a comprehensive study of the most used mobile applications and Wireless Body Area Networks focused on controlling the obesity and overweight. Finally, this paper proposes an intelligent architecture that takes into account both, physiological and cognitive aspects to reduce the degree of obesity and overweight. PMID:29599941

Individuals with chronic spinal cord injury (SCI) are susceptible to central and visceral obesity and it's metabolic consequences; consensus based guidelines for obesity management after SCI have not yet been stablished. To identify and compare effective means of obesity management among SCI individuals. This systematic review included English and non-English articles, published prior to April 2017 found in the PubMed/Medline, Embase, CINAHL Psychinfo and Cochrane databases. Studies evaluating any obesity management strategy, alone or in combination, including: diet therapy, voluntary and involuntary exercise such as neuro-muscular electric stimulation (NMES), pharmacotherapy, and surgery, among individuals with chronic SCI were included. Outcomes of interest were reductions in waist circumference, body weight (BW), body mass index (BMI) and total fat mass (TFM) and increases in total lean body mass (TLBM) from baseline. From 3,553 retrieved titles and abstracts, 34 articles underwent full text review and 23 articles were selected for data abstraction. Articles describing weight loss due to inflammation, cancer or B12 deficiency were excluded. The Downs and Black reported poor to moderate quality of the studies. Bariatric surgery produced the greatest permanent weight reduction and BMI correction followed by combinations of physical exercise and diet therapy. Generally, NMES and pharmacotherapy improved TLBM and reduced TFM but not weight. The greatest weight reduction and BMI correction was produced by bariatric surgery, followed by a combination of physical exercise and diet therapy. NMES and pharmacologic treatment did not reduce weight or TFM but increased in TLBM.
Role of the gastroenterologist in the management of the obese patient.
López-Serrano, Antonio; Ortiz Polo, Inmaculada; Sanz de la Vega, Javier; Moreno-Osset, Eduardo
Obesity is a highly prevalent disease worldwide, and one in which gastroenterologists can play an important role. Some digestive diseases are more common in obese patients, and preoperative evaluation may be required in some cases. Additionally, bariatric surgery can lead to digestive complications in the short and long term that require intervention, and endoscopic treatment can be an important factor in weight loss. The aim of this review is to highlight the role of the gastroenterologist in the management of obese patients who are either scheduled for or have undergone surgical or endoscopic treatment for obesity.

Outcomes of neurofeedback training in childhood obesity management: a pilot study.
Chirita-Emandi, Adela; Puiu, Maria
2014-11-01
This pilot study sought to evaluate the neurofeedback training outcomes in childhood obesity management. The study involved 34 overweight and obese children, age 6-18 years (12 patients in the intervention group, 22 in the control group). Complete assessment of children was done before the intervention and 3 and 6 months after the intervention; eating behavior and quality-of-life questionnaires were assessed at study start and 6 months after. All children received classic lifestyle recommendations for weight management, while the intervention group also had 20 neurofeedback sessions (infra-low-frequency training). The neurofeedback intervention was associated with less weight loss compared with classic weight management. The mean change in body-mass index standard deviation score at 3 months was -0.29 for the intervention group and -0.36 for the control group (p=0.337); after 6 months, the changes were -0.30 and -0.56, respectively (p=0.035). Quality of life improved similarly for both groups. Subjective outcomes reported by patients in the intervention were less snacking, improved satiety, enhanced attention capacity, ameliorated hyperactivity, and better sleep patterns. Larger studies, with training methods involving both the left and right cortices, should further clarify the role of neurofeedback training in obesity management.

Bariatric surgery is today the most effective long-term therapy for the management of patients with severe obesity, and its use is recommended by the relevant guidelines of the management of obesity in adults. Bariatric surgery is in general safe and effective, but it can cause new clinical problems and is associated with specific diagnostic, preventive and therapeutic needs. For clinicians, the acquisition of special knowledge and skills is required in order to deliver appropriate and effective care to the post-bariatric patient. In the present recommendations, the basic notions needed to provide first-level adequate medical care to post-bariatric patients are summarised. Basic information about nutrition, management of co-morbidities, pregnancy, psychological issues as well as weight regain prevention and management is derived from current evidences and existing guidelines. A short list of clinical practical recommendations is included for each item. It remains clear that referral to a bariatric multidisciplinary centre, preferably the one performing the original procedure, should be considered in case of more complex clinical situations.

Anaesthetic management of obese parturients: what is the evidence supporting practice guidelines?
Eley, V A; van Zundert, A A J; Lipman, J; Callaway, L K
2016-09-01
Increasing rates of obesity in western populations present management difficulties for clinicians caring for obese pregnant women. Various governing bodies have published clinical guidelines for the care of obese parturients. These guidelines refer to two components of anaesthetic care: anaesthetic consultation in the antenatal period for women with a body mass index (BMI) ≥ 40 kg/m 2 and the provision of early epidural analgesia in labour. These recommendations are based on the increased incidence of obstetric complications and the predicted risks and difficulties in providing anaesthetic care. The concept behind early epidural analgesia is logical-site the epidural early, use it for surgical anaesthesia and avoid general anaesthesia if surgery is required. Experts support this recommendation, but there is weak supporting evidence. It is known that the management of labour epidurals in obese women is complicated and that women with extreme obesity require higher rates of general anaesthesia. Anecdotally, anaesthetists view and apply the early epidural recommendation inconsistently and the acceptability of early epidural analgesia to pregnant women is variable. In this topic review, we critically appraise these two practice recommendations. The elements required for effective implementation in multidisciplinary maternity care are considered. We identify gaps in the current literature and suggest areas for future research. While prospective cohort studies addressing epidural extension ('top-up') in obese parturients would help inform practice, audit of local practice may better answer the question "is early epidural analgesia beneficial to obese women in my practice?".
Weight management in obese pets: the tailoring concept and how it can improve results.
German, Alexander J
2016-10-20
Obesity is now recognised as the most important medical disease in pets worldwide. All current strategies for weight management involve dietary energy restriction with a purpose-formulated diet. Whilst current weight management regimes can be successful, outcomes are often disappointing with the rate of weight loss progressively slowing down as time goes on. Success is most challenging for the most obese dogs and cats that are more likely to discontinue the programme before reaching target weight. To improve outcomes, clinicians must focus carefully on better tailoring programmes, paying particular to setting an appropriate target weight so as to maximise the benefits for the individual. In this opinionated review, the author will discuss findings from recent clinical research studies examining weight management in obese dogs and cats. A strategy for tailoring weight management targets will then be discussed, illustrated with case examples.
Neoliberal science, Chinese style: Making and managing the 'obesity epidemic'.
Greenhalgh, Susan
2016-08-01
Science and Technology Studies has seen a growing interest in the commercialization of science. In this article, I track the role of corporations in the construction of the obesity epidemic, deemed one of the major public health threats of the century. Focusing on China, a rising superpower in the midst of rampant, state-directed neoliberalization, I unravel the process, mechanisms, and broad effects of the corporate invention of an obesity epidemic. Largely hidden from view, Western firms were central actors at every stage in the creation, definition, and governmental management of obesity as a Chinese disease. Two industry-funded global health entities and the exploitation of personal ties enabled actors to nudge the development of obesity science and policy along lines beneficial to large firms, while obscuring the nudging. From Big Pharma to Big Food and Big Soda, transnational companies have been profiting from the 'epidemic of Chinese obesity', while doing little to effectively treat or prevent it. The China case suggests how obesity might have been constituted an 'epidemic threat' in other parts of the world and underscores the need for global frameworks to guide the study of neoliberal science and policymaking.
Can mHealth Revolutionize the Way We Manage Adult Obesity?
Bhardwaj, Niharika N; Wodajo, Bezawit; Gochipathala, Keerthi; Paul, David P; Coustasse, Alberto
2017-01-01
Obesity is the largest driver of chronic preventable diseases, accounting for an estimated $147 billion or 10 percent of total US healthcare costs in 2008. It has been forecasted that 42 percent of Americans will be obese by 2030. Mobile health (mHealth) technologies target and may modify the behavioral factors that lead to obesity to promote a healthy lifestyle. These technologies could potentially reduce the cost and the morbidity and mortality burden of obesity because of their inexpensive and portable nature. This study aimed to analyze the efficacy and cost-effectiveness of mHealth interventions for adult obesity in the United States. The methodology used in this study was a literature review of 54 articles. Weight, body mass index (BMI), waist circumference reductions, and favorable lifestyle behavior changes were noted across most studies. Existing data and research on efficacy and linked costs indicated that mHealth technologies were more effective than other methods and could be inexpensively delivered remotely to manage adult obesity, offering significant benefits over conventional care. Further studies on the costs and benefits of adapting such mHealth interventions in clinical settings are needed.
Conceptual Model of Weight Management in Overweight and Obese African-American Females.
Sutton, Suzanne M; Magwood, Gayenell S; Nemeth, Lynne S; Jenkins, Carolyn M
2017-04-01
Weight management of overweight and obese (OWO) African-American females (AAFs) is a poorly defined concept, leading to ineffective treatment of overweight and obesity, prevention of health sequelae, and risk reduction. A conceptual model of the phenomenon of weight management in OWO AAFs was developed through dimensional analysis of the literature. Constructs were identified and sorted into the dimensions of perspective, context, conditions, process, and consequences and integrated into an explanatory matrix. Through dimensional analysis, weight management in OWO AAFs was characterized as a multidimensional concept, defined from the perspective of weight loss in community-dwelling AAFs. Behaviors associated with weight management are strongly influenced by intrinsic factors and extrinsic conditions, which influence engagement in the processes and consequences of weight management. The resulting conceptual model of weight management in OWO AAFs provides a framework for research interventions applicable in a variety of settings. © 2016 Wiley Periodicals, Inc.

Despite opportunities for didactic education on obesity management, we still observe low rates of weight management visits in our primary care setting. This paper describes the co-creation by front-line interdisciplinary health care providers and researchers of the 5As Team intervention to improve obesity prevention and management in primary care. We describe the theoretical foundations, design, and core elements of the 5AsT intervention, and the process of eliciting practitioners' self-identified knowledge gaps to inform the curricula for the 5AsT intervention. Themes and topics were identified through facilitated group discussion and a curriculum relevant to this group of practitioners was developed and delivered in a series of 12 workshops. The research question and approach were co-created with the clinical leadership of the PCN; the PCN committed internal resources and a practice facilitator to the effort. Practice facilitation and learning collaboratives were used in the intervention For the content, front-line providers identified 43 topics, related to 13 themes around obesity assessment and management for which they felt the need for further education and training. These needs included: cultural identity and body image, emotional and mental health, motivation, setting goals, managing expectations, weight-bias, caregiver fatigue, clinic dynamics and team-based care, greater understanding of physiology and the use of a systematic framework for obesity assessment (the "4Ms" of obesity). The content of the 12 intervention sessions were designed based on these themes. There was a strong innovation values fit with the 5AsT intervention, and providers were more comfortable with obesity management following the intervention. The 5AsT intervention, including videos, resources and tools, has been compiled for use by clinical teams and is available online at http://www.obesitynetwork.ca/5As_Team .

Effective behaviour change techniques in the prevention and management of childhood obesity.
Martin, J; Chater, A; Lorencatto, F
2013-10-01
Rates of childhood obesity are increasing, and it is essential to identify the active components of interventions aiming to prevent and manage obesity in children. A systematic review of behaviour change interventions was conducted to find evidence of behaviour change techniques (BCTs) that are most effective in changing physical activity and/or eating behaviour for the prevention or management of childhood obesity. An electronic search was conducted for randomised controlled trials published between January 1990 and December 2009. Of 4309 titles and abstracts screened, full texts of 135 articles were assessed, of which 17 published articles were included in this review. Intervention descriptions were coded according to the behaviour-specific CALO-RE taxonomy of BCTs. BCTs were identified and compared across obesity management (n=9) vs prevention (n=8) trials. To assess the effectiveness of individual BCTs, trials were further divided into those that were effective (defined as either a group reduction of at least 0.13 body mass index (BMI) units or a significant difference in BMI between intervention and control groups at follow-up) vs non-effective (reported no significant differences between groups). We reliably identified BCTs utilised in effective and non-effective prevention and management trials. To illustrate the relative effectiveness of each BCT, effectiveness ratios were calculated as the ratio of the number of times each BCT was a component of an intervention in an effective trial divided by the number of times they were a component of all trials. Results indicated six BCTs that may be effective components of future management interventions (provide information on the consequences of behaviour to the individual, environmental restructuring, prompt practice, prompt identification as role model/position advocate, stress management/emotional control training and general communication skills training), and one that may be effective in prevention
Surveillance Systems to Track and Evaluate Obesity Prevention Efforts.
Hoelscher, Deanna M; Ranjit, Nalini; Pérez, Adriana
2017-03-20
To address the obesity epidemic, the public health community must develop surveillance systems that capture data at levels through which obesity prevention efforts are conducted. Current systems assess body mass index (BMI), diet, and physical activity behaviors at the individual level, but environmental and policy-related data are often lacking. The goal of this review is to describe US surveillance systems that evaluate obesity prevention efforts within the context of international trends in obesity monitoring, to identify potential data gaps, and to present recommendations to improve the evaluation of population-level initiatives. Our recommendations include adding environmental and policy measures to surveillance efforts with a focus on addressing underserved populations, harmonizing existing surveillance systems, including more sensitive measures of obesity outcomes, and developing a knowledgeable workforce. In addition, the widespread use of electronic health records and new technologies that allow self-quantification of behaviors offers opportunities for innovative surveillance methods.

Obesity is one of the only modifiable risk factors for both incidence and progression of Osteoarthritis (OA). So there is increasing interest from a public health perspective in addressing obesity in the management of OA. While evidence of the efficacy of intereventions designed to address obesity in OA populations continues to grow, little is known about their economic credentials. The aim of this study is to conduct a scoping review of: (i) the published economic evidence assessing the economic impact of obesity in OA populations; (ii) economic evaluations of interventions designed to explicitly address obesity in the prevention and management of OA in order to determine which represent value for money. Besides describing the current state of the literature, the study highlights research gaps and identifies future research priorities. In July 2014, a search of the peer reviewed literature, published in English, was undertaken for the period January 1975 - July 2014 using Medline Complete (Ebscohost), Embase, Econlit, Global Health, Health Economics Evaluation Database (HEED), all Cochrane Library databases as well as the grey literature using Google and reference lists of relevant studies. A combination of key search terms was used to identify papers assessing the economic impact of obesity in OA or economic evaluations conducted to assess the efficiency of obesity interventions for the prevention or management of OA. 14 studes were identified; 13 were cost burden studies assessing the impact of obesity as a predictor for higher costs in Total Joint Arthroplasty (TJA) patients and one a cost-effectiveness study of an intervention designed to address obesity in the managment of mild to moderate OA patients. The majority of the economic studies conducted are cost burden studies. While there is some evidence of the association between severe obesity and excess hospital costs for TJA patients, heterogeneity in studies precludes definitive statements about the
A Community Based Systems Diagram of Obesity Causes.

Application of system thinking to the development, implementation and evaluation of childhood obesity prevention efforts represents the cutting edge of community-based prevention. We report on an approach to developing a system oriented community perspective on the causes of obesity. Group model building sessions were conducted in a rural Australian community to address increasing childhood obesity. Stakeholders (n = 12) built a community model that progressed from connection circles to causal loop diagrams using scripts from the system dynamics literature. Participants began this work in identifying change over time in causes and effects of childhood obesity within their community. The initial causal loop diagram was then reviewed and elaborated by 50 community leaders over a full day session. The process created a causal loop diagram representing community perceptions of determinants and causes of obesity. The causal loop diagram can be broken down into four separate domains; social influences; fast food and junk food; participation in sport; and general physical activity. This causal loop diagram can provide the basis for community led planning of a prevention response that engages with multiple levels of existing settings and systems.

The problem of obesity affects all age groups. It is also observed among menopausal women. Menopause is the time in a woman's life when, as a consequence of hormonal changes occurring in the body, the risk of overweight and obesity increases significantly and, therefore, so does the risk of metabolic and cardiovascular diseases. Excess body weight in menopausal women may also be of social and psychological importance since the occurring symptoms may considerably decrease quality of life and sexual activity of these women. Reduction of body weight in obese menopausal women should play a vital role in treatment of this group of patients. Therefore, adequate management seems to be essential, and it should involve dietary, pharmacological and/or surgical treatment, depending on the patient's needs. Following a rational weight loss plan provided by a dietician under medical supervision may contribute to improvement of the health condition and quality of life. It is recommended to observe the guidelines on dietary management described in this article by adjusting a diet plan individually. The following work constitutes a review of articles from 2004-2014 which are available in the PubMed medical knowledge base and the Polish Medical Bibliography (Polska Bibliografia Lekarska). For this purpose, the following controlled vocabulary has been used: menopausal woman, menopausal diet, menopausal weight gain, menopausal weight loss, dietary management in menopause.

Primary care clinicians are well-positioned to intervene in the obesity epidemic. We studied whether implementation of an obesity intake protocol and electronic health record (EHR) form to guide behavior modification would facilitate identification and management of adult obesity in a Federally Qualified Health Center serving low-income, Hispanic patients. In three studies, we examined clinician and patient outcomes before and after the addition of the weight management protocol and form. In the Clinician Study, 12 clinicians self-reported obesity management practices. In the Population Study, BMI and order data from 5000 patients and all 40 clinicians in the practice were extracted from the EHR preintervention and postintervention. In the Exposure Study, EHR-documented outcomes for a sub-sample of 46 patients actually exposed to the obesity management form were compared to matched controls. Clinicians reported that the intake protocol and form increased their performance of obesity-related assessments and their confidence in managing obesity. However, no improvement in obesity management practices or patient weight-loss was evident in EHR records for the overall clinic population. Further analysis revealed that only 55 patients were exposed to the form. Exposed patients were twice as likely to receive weight-loss counseling following the intervention, as compared to before, and more likely than matched controls. However, their obesity outcomes did not differ. Results suggest that an obesity intake protocol and EHR-based weight management form may facilitate clinician weight-loss counseling among those exposed to the form. Significant implementation barriers can limit exposure, however, and need to be addressed. © The Author 2015.

To investigate what weight management interventions work for men, with which men, and under what circumstances. Realist synthesis of qualitative studies. Sensitive searches of 11 electronic databases from 1990 to 2012 supplemented by grey literature searches. Studies published between 1990 and 2012 reporting qualitative research with obese men, or obese men in contrast to obese women and lifestyle or drug weight management were included. The studies included men aged 16 years or over, with no upper age limit, with a mean or median body mass index of 30 kg/m(2) in all settings. 22 studies were identified, including 5 qualitative studies linked to randomised controlled trials of weight maintenance interventions and 8 qualitative studies linked to non-randomised intervention studies, and 9 relevant UK-based qualitative studies not linked to any intervention. Health concerns and the perception that certain programmes had 'worked' for other men were the key factors that motivated men to engage with weight management programmes. Barriers to engagement and adherence with programmes included: men not problematising their weight until labelled 'obese'; a lack of support for new food choices by friends and family, and reluctance to undertake extreme dieting. Retaining some autonomy over what is eaten; flexibility about treats and alcohol, and a focus on physical activity were attractive features of programmes. Group interventions, humour and social support facilitated attendance and adherence. Men were motivated to attend programmes in settings that were convenient, non-threatening and congruent with their masculine identities, but men were seldom involved in programme design. Men's perspectives and preferences within the wider context of family, work and pleasure should be sought when designing weight management services. Qualitative research is needed with men to inform all aspects of intervention design, including the setting, optimal recruitment processes and
Childhood obesity: knowledge, attitudes, and practices of European pediatric care providers.

To determine and compare attitudes, skills, and practices in childhood obesity management in 4 European countries with different obesity prevalence, health care systems, and economic situations. A cross-sectional survey was distributed to primary health care providers from France, Italy, Poland, and Ukraine. The questionnaire was returned by 1119 participants with a response rate of 32.4%. The study revealed that most of the primary health care providers were convinced of their critical role in obesity management but did not feel sufficiently competent to perform effectively. The adherence to recommended practices such as routine weight and height measurements, BMI calculation, and plotting growth parameters on recommended growth charts was poor. Most primary health care providers recognized the need for continuing professional education in obesity management, stressing the importance of appropriate dietary counseling. The study underlines insufficient implementation of national guidelines for management of obesity regardless of the country and its health system. It also makes clear that the critical problem is not elaboration of guidelines but rather creating support systems for implementation of the medical standards among the primary care practitioners.

Endoscopic sleeve gastroplasty (the Apollo method): a new approach to obesity management.
López-Nava Breviere, Gontrand; Bautista-Castaño, Inmaculada; Fernández-Corbelle, Juan Pedro; Trell, Marta
2016-04-01
Many obese patients cannot lose weight or reject conventional obesity management. Endoscopic sleeve gastroplasty (the Apollo method) is a pioneering coadjuvant, interventionist technique for the integral management of obesity. The goals of this study were to report safety and efficacy results obtained at 6 months in patients undergoing endoscopic sleeve gastroplasty. A prospective study was performed in 55 patients (13 males, 42 females) who were subjected to the Apollo technique; mean age was 43.5 years (range 25-60) and mean BMI was 37.7 kg/m2 (range 30-48). All received multidisciplinary follow-up for weight loss. Weight changes and presence of complications were assessed. Through the endoscope a triangular pattern suture is performed consisting of approximately 3-6 transmural (mucosa to serosa) stitches, using a cinch device to bring them nearer and form a plication. A total of 6-8 plications are used to provide a tubular or sleeve-shaped restriction to the gastric cavity. No major complications developed and patients were discharged at 24 hours following the procedure. Endoscopic and radiographic follow-up at 6 months post-procedure showed a well preserved tubular form to the stomach. After 6 months patients had lost 18.9 kg and 55.3% of excess weight. Endoscopic sleeve gastroplasty, together with dietary and psycho-behavioral changes, is a safe, effective technique in the coadjuvant management of obese patients.
Key issues in the prevention of obesity.
Gill, T P
1997-01-01
Obesity is a serious, chronic medical condition which is associated with a wide range of debilitating and life-threatening conditions. It imposes huge financial burdens on health care systems and the community at large. Obesity develops over time and once it has done so, is difficult to treat. Therefore, the prevention of weight gain offers the only truly effective means of controlling obesity. Very little research has directly addressed the issue of obesity prevention and previous efforts to prevent obesity amongst individuals, groups or whole communities have had very limited success. However, we have learned sufficient from past preventive activities to realise that the management of obesity will require a comprehensive range of strategies with actions that target those with existing weight problems, those at high risk of developing obesity as well as the community as a whole. The prevention and management of obesity in children should be considered a priority as there is a high risk of persistence into adulthood.
Management of obesity in children differs from that of adults.

Obesity in childhood is a very common disorder with an increasing prevalence. It is one of the most serious public health challenges. The objectives of the present paper are to increase the awareness of the problem of obesity in childhood, its serious complications and the need for prevention. Overweight and obese children are likely to remain obese into adulthood and more likely to develop serious complications including health problems such as diabetes and CVD, as well as psychological and social challenges. Overweight and obesity are largely preventable. In adults it is difficult to reduce excessive weight gain once it has become established, thus children should be considered the priority population for intervention strategies and prevention. Nutrition, exercise, weight gain in infancy, genetic and environmental factors, all contribute to the aetiology. Prevention and treatment of obesity in childhood requires education and empowerment of families relating to diet and exercise, along with the regulation and control of food marketing and clear nutritional labelling. The eating and physical activity behaviour of a child is strongly influenced by environmental and social factors. Therefore treatment will have only limited success in an environment where adequate physical activity is inhibited and the consumption of high-energy food is stimulated. Government investment in a health promotion programme addressing the issue of obesity in the population as a whole, with particular emphasis on the prevention and management of obesity in childhood is vital. The family doctor and multidisciplinary team play an important role. Regular visits to the family doctor, including growth assessment, will help motivate the family to restrict energy intake and to increase exercise. Therefore the prevention of childhood obesity needs high priority.

This descriptive study examines the prevalence of obesity-related cardiometabolic (CM) risk factors using CM laboratory metrics, in 3 to 19 year olds presenting to a rural American Academy of Pediatrics stage 3 multidisciplinary weight management clinic based on gender, age ranges, and obesity classes. From 2009 to 2016, 382 children (body mass index ≥85th percentile) enrolled. Multiple logistic regression determined the effects of age, gender, or obesity class on CM risk factors. Odds of elevated insulin were more significant in 15 to 19 year olds than in 3 to 5 year olds, or in 6 to 11 year olds. Obesity class III had higher odds than class II, class I, and overweight in having elevated insulin; twice likely than class II for having low high-density lipoprotein; and twice as likely than class I for high triglycerides. Adolescents and obesity class III categories have significant CM risk but the burden in younger and less severe obesity cohorts cannot be underestimated.

Background : Community-based initiatives show promise for preventing childhood obesity. They are characterized by community leaders and members working together to address complex local drivers of energy balance. Objectives : To present a protocol for a stepped wedge cluster randomized trial in ten communities in the Great South Coast Region of Victoria, Australia to test whether it is possible to: (1) strengthen community action for childhood obesity prevention, and (2) measure the impact of increased action on risk factors for childhood obesity. Methods: The WHO STOPS intervention involves a facilitated community engagement process that: creates an agreed systems map of childhood obesity causes for a community; identifies intervention opportunities through leveraging the dynamic aspects of the system; and, converts these understandings into community-built, systems-oriented action plans. Ten communities will be randomized (1:1) to intervention or control in year one and all communities will be included by year three. The primary outcome is childhood obesity prevalence among grade two (ages 7-8 y), grade four (9-10 y) and grade six (11-12 y) students measured using our established community-led monitoring system (69% school and 93% student participation rate in government and independent schools). An additional group of 13 external communities from other regions of Victoria with no specific interventions will provide an external comparison. These communities will also allow us to assess diffusion of the intervention to control communities during the first three years of the trial. Conclusion : This trial will test effectiveness, over a five-year period, of community-owned, -supported and -led strategies designed to address complex and dynamic causes of childhood obesity.

Management of obesity: improvement of health-care training and systems for prevention and care.

Although the caloric deficits achieved by increased awareness, policy, and environmental approaches have begun to achieve reductions in the prevalence of obesity in some countries, these approaches are insufficient to achieve weight loss in patients with severe obesity. Because the prevalence of obesity poses an enormous clinical burden, innovative treatment and care-delivery strategies are needed. Nonetheless, health professionals are poorly prepared to address obesity. In addition to biases and unfounded assumptions about patients with obesity, absence of training in behaviour-change strategies and scarce experience working within interprofessional teams impairs care of patients with obesity. Modalities available for the treatment of adult obesity include clinical counselling focused on diet, physical activity, and behaviour change, pharmacotherapy, and bariatric surgery. Few options, few published reports of treatment, and no large randomised trials are available for paediatric patients. Improved care for patients with obesity will need alignment of the intensity of therapy with the severity of disease and integration of therapy with environmental changes that reinforce clinical strategies. New treatment strategies, such as the use of technology and innovative means of health-care delivery that rely on health professionals other than physicians, represent promising options, particularly for patients with overweight and patients with mild to moderate obesity. The co-occurrence of undernutrition and obesity in low-income and middle-income countries poses unique challenges that might not be amenable to the same strategies as those that can be used in high-income countries.

Both providers and patients may have important insights to inform the development of obesity prevention and management services in Canadian primary care settings. In this formative study, insights for new obesity management services were sought from both providers and patients in 1 progressive citywide organization (150 physicians, team services, separate offices). Seven focus groups with interprofessional health providers (n = 56) and 4 focus groups with patients (n = 34) were conducted. Two clinical vignettes (adult, child) were used to focus discussion. Four analysts coded for descriptive content and interpretative themes on possible tools and care processes using NVivo. Participants identified numerous strategies for care processes, most of which could be categorized into 1 or more of 11 themes: 6 directed at clinical care of patients (raising awareness, screening, clinical care, skill building, ongoing support, and social/peer support) and 5 directed at the organization (coordination/collaboration, creating awareness among health professionals, adding new expertise to the team, marketing, and lobbying/advocacy). The approach was successful in generating an extensive list of diverse activities to be considered for implementation studies. Both patients and providers identified that multiple strategies and systems approaches will be needed to address obesity management in primary care.

In an attempt to determine the principles of diet management in obese pregnant women, the association between maternal weight gain during pregnancy (Group I; weight reduction, Group II; +0-4 kg, Group III; +5-9 kg, Group IV; +10 kg-) and the incidence of the complications was investigated in 151 obese pregnant women. Studies on glucose tolerance and insulin binding to erythrocytes were also undertaken. 1) In Group I, the incidences of C/S, forceps delivery, prolonged labor and complication of PIH were lower than those of other groups. There were no heavy-for-dates and light-for-dates babies in Group I, differing from the other three groups. 2) Plasma levels of glucose and insulin were high in obese pregnant women on 75 g OGTT in the second trimester. The binding sites of insulin to erythrocytes were significantly decreased in obese pregnant women. In conclusion, the risks of pregnancy complicated by obesity were high. Insulin resistance was a characteristic of obese pregnant women. The results of this study suggested that the nutritional requirements for very obese pregnant women should be restricted to maintaining the same weight or losing weight during the course of pregnancy to minimize maternal and perinatal risks.
Population-based worksite obesity management interventions: a qualitative case study.
Romney, Martha C; Thomson, Erin; Kash, Kathryn
2011-06-01
Due to the increased prevalence of obesity and associated direct and indirect costs to employers, weight management programs have become an integral component of employer and insurer benefits plans. The programs vary in foci, scope, breadth, and implementation. The aim of this study was to explore promising employer-sponsored population-based obesity management programs. A case study that utilized a telephonic semi-structured questionnaire was conducted with small and large organizations located in different regions of the United States that had been recruited to participate. Eight employers and 1 health care advocacy coalition who met the inclusion criteria were interviewed about features of their weight management programs. The case study revealed a number of themes consistent with reports in the literature and reflecting cited best practices. Key findings include confirmation that weight management is a significant component of the wellness strategy in all participating organizations because employers are invested in population health programs and cost savings. Based upon their experience and knowledge, occupational health specialists are responsible for designing, implementing, managing, and evaluating employee health programs. Almost all employers utilize electronic media as a prominent component of wellness and disease management initiatives. Experience has shown that incentives-both financial and nonmonetary-are effective motivators for employee engagement and outcomes. However, while employers report success, favorable outcomes have been difficult to quantify.

To assess the practice patterns and personal beliefs of fertility physicians who care for obese patients seeking assisted reproduction, we conducted a national survey of fertility program directors from both private and academic practices and discovered that although few practices have firm guidelines regarding the management of obese patients, the overwhelming majority of providers believe that body mass index guidelines or cutoffs should exist.

How can primary care providers manage pediatric obesity in the real world?
Hopkins, Kristy F; Decristofaro, Claire; Elliott, Lydia

To provide information regarding evidence-based interventions and clinical practice guidelines as a basis for a clinical toolkit utilizing a step management approach for the primary care provider in managing childhood obesity. Evidence-based literature including original clinical trials, literature reviews, and clinical practice guidelines. Interventions can be stratified based on initial screening of children and adolescents so that selection of treatment options is optimized. For all treatments, lifestyle modifications include attention to diet and activity level. Levels of initial success, as well as maintenance of target body mass index, may be related to the intensity and duration of interventions; involvement of family may increase success rates. For failed lifestyle interventions, or for patients with extreme obesity and/or certain comorbidities, pharmacologic or surgical options should be considered. Many intensive programs have shown success, but the resources required for these approaches may be unavailable to the typical community provider and family. However, using current guidelines, the primary care provider can initiate and manage ongoing interventions in pediatric obesity. A toolkit for primary care implementation and maintenance interventions is provided. ©2011 The Author(s) Journal compilation ©2011 American Academy of Nurse Practitioners.

To assess the Health and Obesity: Prevention and Education (HOPE) Curriculum Project, a web-based clinician education program that promotes appropriate screening, prevention, and management of weight among youth by pediatric practitioners, based on the 2007 Expert Committee recommendations. The project currently provides Maintenance of Certification (MOC) Part 4 credit through the American Board of Pediatrics. Participants identified themselves to the HOPE MOC Part 4 program. Enrollees were required to complete all continuing medical education modules (10.5 hours). Knowledge acquisition and self-reported confidence levels related to screening, prevention, and management practices of pediatric obesity were measured using preknowledge and postknowledge questionnaires. Participants were also required to perform a quality improvement project and submit practice performance data from repeated medical chart reviews over time. Knowledge acquisition, self-efficacy, and practice performance data were analyzed using repeated-measures analyses. The 51 participants demonstrated significant improvements in knowledge acquisition and self-efficacy scores after viewing individual modules. In addition, participants demonstrated significant improvements in measured clinical compliance with recommended practices over time. Participation in the HOPE MOC Part 4 program appeared to improve knowledge acquisition, self-efficacy, and physician compliance with recommended practice recommendations for the screening, prevention, and management of pediatric obesity. Further data are required to determine whether such practice-based improvements translate into actual reduction in patient weight and/or reduction in health-related costs related to overweight and obesity in youth.

Over 60% of people have overweight or obesity, but only a third report receiving counselling from primary care providers. We explored patients' perspectives on the role of primary care in obesity management and their experience with existing resources, with a view to develop an improved understanding of this perspective, and more effective management strategies. Qualitative study employing semi-structured interviews and thematic analysis, with a sample of 28 patients from a cohort of 255 patients living with obesity and receiving care to support their weight management in a large Primary Care Network of family practices in Alberta. Four illustrative themes emerged: (1) the patient-physician relationship plays an important role in the adequacy of obesity management; (2) patients have clear expectations of substantive conversations with their primary care team; (3) complex conditions affect weight and patients require assistance tailored to individual obesity drivers; (4) current services provide support in important ways (accessibility, availability, accountability, affordability, consistency of messaging), but are not yet meeting patient needs for individual plans, advanced education, and follow-up opportunities. Patients have clear expectations that their primary care physician asks them about weight within a supportive therapeutic relationship. They see obesity as a complex phenomenon with multiple drivers. They want their healthcare providers to assess and address their root causes - not simplistic advice to "eat less, move more". Patients felt that the current services were positive resources, but expressed needs for tailored weight management plans, and longer-term follow-up.

There have been consistent recommendations for multicomponent and multidisciplinary approaches for obesity management. However, there is no clear agreement on the components, disciplines or processes to be considered within such an approach. In this study, we explored multicomponent and multidisciplinary approaches through an examination of knowledge, skills, beliefs, and recommendations of stakeholders involved in obesity management. These stakeholders included researchers, practitioners, educators, and patients. We used qualitative action research methods, including convergent interviewing and observation, to assist the process of inquiry. The consensus was that a multicomponent and multidisciplinary approach should be based on four central meta-components (patient, practitioner, process, and environmental factors), and specific components of these factors were identified. Psychologists, dieticians, exercise physiologists and general practitioners were nominated as key practitioners to be included. A complex condition like obesity requires that multiple components be addressed, and that both patients and multiple disciplines are involved in developing solutions. Implementing cycles of continuous improvement to deal with complexity, instead of trying to control for it, offers an effective way to deal with complex, changing multisystem problems like obesity.
Principles and pitfalls in the differential diagnosis and management of childhood obesities.

Obesity is currently the most prevalent chronic childhood disease in Western countries. It is one of the most frequent consultations in general pediatrics and is even more common in pediatric endocrinology. As might be predicted, the prevalence of obesity-associated comorbidities is also increasing in children and adolescents. It is widely accepted that this increase in obesity results from an imbalance between energy intake and expenditure, with an increase in positive energy balance being closely associated with the current lifestyle in Western countries. However, there is increasing evidence indicating that an individual's genetic background is important in determining obesity risk. The physiologic mechanisms controlling appetite and energy expenditure are being revealed in part because of the identification of new causes of human monogenic, syndromic, and endocrine-related obesity. Thus, it is no longer appropriate to talk about obesity, but rather about "obesities" or "different diseases causing obesity," because their pathophysiologic bases differ. Moreover, these obesities require different diagnostic and management approaches. The pediatrician must be aware of this issue and focus the clinical history and physical examination toward specific clinical signs and symptoms to better exploit the available diagnostic and therapeutic resources when facing a child with obesity. Genetic, genomic, and metabolomic studies are often necessary to obtain a more appropriate diagnosis. Cognitive behavioral therapy is fundamental in obese children. The identification of potential targets will hopefully result in new pharmacologic approaches for translational and personalized medicine for obesity in the near future. © 2014 American Society for Nutrition.

An early and accurate recognition of success in treating obesity may increase the compliance of obese children and their families to intervention programs. This observational, prospective study aimed to evaluate the ability and the time to detect a significant reduction of adiposity estimated by body mass index (BMI), percentage of fat mass (%FM), and fat mass index (FMI) during weight management in prepubertal obese children. In a cohort of 60 prepubertal obese children aged 3-9 years included in an outpatient weight management program, BMI, %FM, and FMI were monitored monthly; the last two measurements were assessed using air displacement plethysmography. The outcome measures were the reduction of >5% of each indicator and the time to achieve it. The rate of detection of the outcome was 33.3% (95% CI: 25.9-41.6) using BMI, significantly lower (p<0.001) than either 63.3% using %FM (95% CI: 50.6-74.8) or 70.0% (95% CI: 57.5-80.1) using FMI. The median time to detect the outcome was 71 days using FMI, shorter than 88 days using %FM, and similar to 70 days using BMI. The agreement between the outcome detected by FMI and by %FM was high (kappa 0.701), but very low between the success detected by BMI and either FMI (kappa 0.231) or %FM (kappa 0.125). FMI achieved the best combination of ability and swiftness to identify reduction of adiposity during monitoring of weight management in prepubertal obese children.

This study evaluated the effects of obesity on health-related quality of life (HRQOL) measures in juvenile-onset systemic lupus erythematosus (jSLE). Obesity was defined as a body mass index (BMI) ≥ 95 th percentile according to the Sex-specific Center for Disease Control BMI-For-Age Charts and determined in a multicenter cohort of jSLE patients. In this secondary analysis, the domain and summary scores of the Pediatric Quality of Life (PedsQL) Inventory and the Child Health Questionnaire (CHQ) of obese jSLE patients were compared to those of non-obese jSLE patients as well as historical obese and non-obese healthy controls. Mixed-effects modeling was performed to evaluate the relationship between obesity and HRQOL measures. Among the 202 jSLE patients, 25% (n = 51) were obese. Obesity had a significant negative impact on HRQOL in jSLE, even after adjusting for differences in current corticosteroid use, disease activity, disease damage, gender and race between groups. Obese jSLE patients had lower physical functioning compared to non-obese jSLE patients, and to non-obese and obese healthy controls. Compared to their non-obese counterparts, obese jSLE patients also had worse school functioning, more pain, worse social functioning and emotional functioning. Parents of obese jSLE patients worry more. The CHQ scores for obese jSLE patients were also worse compared to non-obese jSLE patients in several other domains. Our study demonstrates the detrimental effects of obesity on patient-reported outcomes in jSLE. This supports the importance of weight management for the therapeutic plan of jSLE. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Kaiser Permanente, an integrated health care delivery system in the USA, takes a "whole systems" approach to the chronic disease of obesity that begins with efforts to prevent it by modifying the environment in communities and schools. Aggressive case-finding and substantial investment in intensive lifestyle modification programs target individuals at high risk of diabetes and other weight-related conditions. Kaiser Permanente regions are increasingly standardizing their approach when patients with obesity require treatment intensification using medically supervised diets, prescription medication to treat obesity, or weight loss surgery.

The management of obesity is complex and it must be multidisciplinary. Behavioral treatments for control of childhood obesity are based on family; these have a high degree of efficiency. It has been argued that when children and their parents are the main goal of the changes of behavior as a group, results of weight loss generally are better. The objective of this study was to establish the effect of an intervention based on family to reduce weight in students with overweight or obesity. Quasi-experimental study in schoolchildren from 6 to 12 years of age, from a family medicine unit in Ciudad Obregón, Sonora, México. The intervention group corresponded to 30 schoolchildren with overweight or obesity, and one or both of their parents with overweight or obesity; the control group included 30 schoolchildren with overweight or obesity, and normal-weight parents. Weight, height and body mass index (BMI) were measured at baseline, monthly, and at the end of the study. Student t test was used to contrast quantitative variables using the SPSS v.15 program. There were differences in weight, but not in BMI, probably due to the effect of size. Compared with the control group, a higher proportion of schoolchildren showed an improvement with regard to nutritional status. The family intervention is basic for the treatment of overweight and obesity in schoolchildren.
Obesity in pregnancy: risks and management
Fitzsimons, Kate J; Modder, Jo; Greer, Ian A
2009-01-01
Maternal obesity is now considered one of the most commonly occurring risk factors seen in obstetric practice. Compared with women with a healthy pre-pregnancy weight, women with obesity are at increased risk of miscarriage, gestational diabetes, preeclampsia, venous thromboembolism, induced labour, caesarean section, anaesthetic complications and wound infections, and they are less likely to initiate or maintain breastfeeding. Babies of obese mothers are at increased risk of stillbirth, congenital anomalies, prematurity, macrosomia and neonatal death. Intrauterine exposure to obesity is also associated with an increased risk of developing obesity and metabolic disorders in childhood. This article reviews the prevalence of obesity in pregnancy and the associated maternal and fetal complications. Recommendations and suggestions for pre-conception, antenatal and postnatal care of women with obesity are presented, and current research in the UK and future research priorities are considered.

Extreme obesity is a core phenotypic feature of Prader-Willi syndrome (PWS). Among numerous metabolic regulators, the endocannabinoid (eCB) system is critically involved in controlling feeding, body weight, and energy metabolism, and a globally acting cannabinoid-1 receptor (CB 1 R) blockade reverses obesity both in animals and humans. The first-in-class CB 1 R antagonist rimonabant proved effective in inducing weight loss in adults with PWS. However, it is no longer available for clinical use because of its centrally mediated, neuropsychiatric, adverse effects. We studied eCB 'tone' in individuals with PWS and in the Magel2 -null mouse model that recapitulates the major metabolic phenotypes of PWS and determined the efficacy of a peripherally restricted CB 1 R antagonist, JD5037 in treating obesity in these mice. Individuals with PWS had elevated circulating levels of 2-arachidonoylglycerol and its endogenous precursor and breakdown ligand, arachidonic acid. Increased hypothalamic eCB 'tone', manifested by increased eCBs and upregulated CB 1 R, was associated with increased fat mass, reduced energy expenditure, and decreased voluntary activity in Magel2 -null mice. Daily chronic treatment of obese Magel2 -null mice and their littermate wild-type controls with JD5037 (3 mg/kg/d for 28 days) reduced body weight, reversed hyperphagia, and improved metabolic parameters related to their obese phenotype. Dysregulation of the eCB/CB 1 R system may contribute to hyperphagia and obesity in Magel2 -null mice and in individuals with PWS. Our results demonstrate that treatment with peripherally restricted CB 1 R antagonists may be an effective strategy for the management of severe obesity in PWS.

Childhood obesity has serious consequences both immediately and in adulthood. The rates of obesity in children and adolescents are rising rapidly in the Middle East and North Africa (MENA) region. We systematically searched the literature to explore adverse effects associated with childhood obesity in this region and the management efforts for dealing with it. Inclusion criteria were: English-language, non-basic-science focused articles that used any of the standard obesity definitions and were conducted in the MENA countries within the last five years. We searched PubMed using combinations of key terms ((childhood) OR adolescence) AND obesity) AND (MENA or each country) AND ("last five years" [PDat]). Studies that examined adverse effects of childhood obesity gave fairly consistent results, revealing associations with higher blood pressure, pre-diabetes, metabolic abnormalities, and cardiovascular risk. Little or no overall effect on rates of childhood obesity has yet been demonstrated by interventions used to manage the problem. Obesity has a considerable impact on the health of children and adolescents, and the countries of the MENA region should endorse strategies and programs to prevent and manage this problem in an effective way.

Experts recommend that clinicians assess motivational factors before initiating care for pediatric obesity. Currently, there are no well-established clinical tools available for assessing motivation in youth with obesity or their families. This represents an important gap in knowledge since motivation-related information may shed light on which patients might fail to complete treatment programs. Our study was designed to evaluate the measurement properties and utility of the Readiness and Motivational Interview for Families (RMI-Family), a structured interview that utilizes a motivational interviewing approach to (i) assess motivational factors in youth and their parents, and (ii) examine the degree to which motivation and motivation-related concordance between youth and parents are related to making changes to lifestyle habits for managing obesity in youth. From 2016 to 2020, this prospective study will include youth with obesity (body mass index [BMI] ≥97th percentile; 13-17 years old; n = 250) and their parents (n = 250). The study will be conducted at two primary-level, multidisciplinary obesity management clinics based at children's hospitals in Alberta, Canada. Participants will be recruited and enrolled after referral to these clinics, but prior to initiating clinical care. Each youth and their parent will complete the RMI-Family (~1.5 h) at baseline, and 6- and 12-months post-baseline. Individual (i.e., youth or parent) and family-level (i.e., across youth and parent) responses to interview questions will be scored, as will aspects of interview administration (e.g., fidelity to motivational interviewing tenets). The RMI-Family will also be examined for test-retest reliability. Youth data collected at each time point will include demography, anthropometry, lifestyle habits, psychosocial functioning, and health services utilization.

Critically ill morbidly obese patients pose considerable healthcare delivery and resource utilisation challenges in the intensive care setting. These are resultant from specific physiological responses to critical illness in this population and the nature of the interventional therapies used in the intensive care environment. An additional challenge arises for this population when considering the social stigma that is attached to being obese. Intensive care staff therefore not only attend to the physical and care needs of the critically ill morbidly obese patient but also navigate, both personally and professionally, the social terrain of stigma when providing care. To explore the culture and influences on doctors and nurses within the intensive care setting when caring for critically ill morbidly obese patients. A focused ethnographic approach was adopted to elicit the 'situated' experiences of caring for critically ill morbidly obese patients from the perspectives of intensive care staff. Participant observation of care practices and interviews with intensive care staff were undertaken over a four month period. Analysis was conducted using constant comparison technique to compare incidents applicable to each theme. An 18 bedded tertiary intensive care unit in New Zealand. Sixty-seven intensive care nurses and 13 intensive care doctors involved with the care and management of seven critically ill patients with a body mass index ≥40kg/m(2). Interactions between intensive care staff and morbidly obese patients were challenging due to the social stigma surrounding obesity. Social awkwardness and managing socially awkward moments were evident when caring for morbidly obese patients. Intensive care staff used strategies of face-work and mutual pretence to alleviate feelings of discomfort when engaged in aspects of care and caring. This was a strategy used to prevent embarrassment and distress for both the patients and staff. This study has brought new understandings

Obesity is increasing throughout the industrialised world. If left unchecked it will have major implications for both population health and costs to health services. Health professionals have a key role to play in tackling the obesity problem, but little is known about how they may be encouraged to work more effectively with overweight and obese people. The main objective was to determine whether health professionals' management or the organisation of care for overweight and obese people could be improved. We searched the specialised registers of the Cochrane Effective Practice and Organisation of Care Group (May 1997), the Cochrane Depression, Anxiety and Neurosis Group (August 1997), the Cochrane Diabetes Group (August 1997), the Cochrane Controlled Trials Register (September 1997), MEDLINE to January 1998, EMBASE to December 1997, Cinahl (1982 to November 1997), PsycLit (1974 to December 1997), Sigle (1980 to November 1997), Sociofile (1974 to October 1997), Dissertation Abstracts (1861 to January 1998), Conference Papers Index (1973 to January 1998), Resource Database in Continuing Medical Education. We also hand searched seven key journals and contacted experts in the field. Randomised trials, controlled before-and-after studies and interrupted time series analyses of providers' management of obesity or the organisation of care to improve provider practice or patient outcomes. We addressed three a priori comparisons and a fourth post hoc comparison. 1. Interventions aimed at improving health professionals' management or the delivery of health care for overweight/obese patients are more effective than usual care. 2. Interventions aimed at redressing negative attitudes and related practices towards overweight/obese patients are more effective than usual care. 3. Organisational interventions designed to change the structure of services for overweight/obese people are more effective than educational or behavioural interventions for health professionals. 4
Role of Endoscopic Gastroplasty Techniques in the Management of Obesity.
Jung, Yunho
2017-01-01
Health and wellness represent a major global concern. Trends such as a lack of exercise and excessive consumption of calories are major causes of the rapid increase in obesity worldwide. Obesity should be controlled because it can result in other illnesses, such as diabetes, high blood pressure, high cholesterol, coronary artery disease, stroke, breathing disorders, or cancer. However, many people have difficulty in managing obesity through exercise, dietary control, behavioral modifications, and drug therapy. Bariatric surgery is not commonly used due to a variety of complications, even though it has been demonstrated to produce reliable results with respect to adequate weight loss when performed using an open or a laparoscopic approach. Endoscopic bariatric procedures are emerging techniques that are less invasive and safer compared with current surgical approaches. However, the evaluation of endoluminal procedures is limited by the small number of studies and their short-term follow-up.
ROLE OF SYMPATHETIC NERVOUS SYSTEM IN OBESITY RELATED HYPERTENSION
da Silva, Alexandre; doCarmo, Jussara; Dubinion, John; Hall, John E.
2010-01-01
Obesity is recognized as a major, worldwide, health problem. Excess weight is a major cause of increased blood pressure in most patients with essential hypertension, and greatly increases the risk for diabetes, cardiovascular diseases, and end stage renal disease. Although the mechanisms by which obesity raises blood pressure are not completely understood, increased renal sodium reabsorption, impaired pressure natriuresis, and volume expansion appear to play important roles. Several potential mechanisms have been suggested to contribute to altered kidney function and hypertension in obesity, including activation of the sympathetic nervous system (SNS) and the renin-angiotensin-aldosterone system (RAAS), and physical compression of the kidneys, especially when visceral obesity is present. Activation of the SNS in obesity may be due, in part, to hyperleptinemia and other factors secreted by adipocytes and the gastrointestinal tract, activation of the central nervous melanocortin pathway, and baroreceptor dysfunction.

Despite the high prevalence of childhood overweight and obesity enrolment to weight management programs remains difficult, time consuming, costly and has limited effectiveness. The aim of this paper was to explore parents' perspectives on factors that influence their decision to enrol in a program to address their child's weight. Semi-structured qualitative telephone interviews were undertaken with 21 parents of primary school aged children above the healthy weight range who had enrolled in a healthy lifestyle program. Questions were developed and analysed using the Theory of Planned Behaviour. They addressed parental reasons for enrolment, expectations of the program and apprehensions regarding enrolling. Prior to deciding to enrol, parents tended to be aware of the child's weight status, had attempted to address it themselves and had sought help from a number of people including health professionals. Parental decision to enrol was influenced by their evaluation of their previous attempts and their child's emotional state. Awareness of their child's weight status is an important first step in parents taking action at this health issue however it is unlikely to be sufficient on its own. Parental decision to join a childhood obesity management program can be complex and is likely to be made after numerous and unsuccessful attempts to address the child's weight. Strategies to encourage parents to enrol in programs should include activities beyond awareness of weight status. Health professionals should use contact time with parents to raise awareness of the child's weight status and to provide encouragement to address overweight and obesity. Parents must be supported in their attempts to address their child's overweight and obesity whether they choose to manage it themselves or within a program.
A working paradigm for the treatment of obesity in gastrointestinal practice
Acosta, Andres; Camilleri, Michael
2017-01-01
Obesity is a chronic, relapsing, multi-factorial disease characterized by abnormal or excessive adipose tissue accumulation that may impair health and increase disease risks. Despite the ever-increasing prevalence and economic and societal burden, the current approaches to treat obesity are not standardized or generally effective. In this manuscript, we describe a current working paradigm developed by a consensus approach for the multidisciplinary treatment of obesity in the GI practice. Obesity should be managed as a continuum of care focusing on weight loss, weight loss maintenance and prevention of weight regain. This approach needs to be disseminated throughout the health care system, coordinated by a multidisciplinary team and include gastroenterologists who are in a unique position to address obesity. Gastroenterologists are in the front line of managing the morbidity resulting from obesity, and have expertise in use of the essential tools to manage obesity: nutrition, pharmacology, endoscopy and surgery.

Addressing Pediatric Obesity in Clinic
Pujalte, George G. A.; Ahanogbe, Isabella; Thurston, McKennan J.; White, Richard O.; Roche-Green, Alva
2017-01-01
There is an epidemic of pediatric obesity in the United States. In most cases, there is an excess in the amount of calories consumed, compared with the amount of calories expended. Numerous body systems are affected by pediatric obesity, with complications varying between boys and girls. Behavioral, genetic, and environmental factors affect the ability of children to avoid becoming obese. Primary care physicians should screen for obesity in children as much as possible. Associated risk factors for obesity should be uncovered. Methods of preventing obesity should be discussed routinely with children and their families. Healthy dietary habits are key, and so are family-oriented interventions, such as eating together at dinnertime. One hour of moderate to vigorous activity daily is recommended for children and adolescents. While pediatric bariatric surgery is an option, there are also numerous nonpharmacological and pharmacological measures available as management for pediatric obesity. Family-based approaches, such as reducing screen time, have been very successful. Non–weight-bearing exercises also help children and adolescents expend calories without causing injury to themselves. Family availability, activity preference, and developmental levels should all be considerations when managing pediatric obesity. Motivational interviewing may also be helpful, especially when customized for each specific patient and family. Clinicians will play an increasing role in terms of identifying, treating, and preventing pediatric obesity; measures that can be done in the clinic should be considered more and more. PMID:29119130
Agricultural policy and childhood obesity: a food systems and public health commentary.
Wallinga, David
2010-01-01
For thirty-five years, U.S. agriculture has operated under a "cheap food" policy that spurred production of a few commodity crops, not fruit or vegetables, and thus of the calories from them. A key driver of childhood obesity is the consumption of excess calories, many from inexpensive, nutrient-poor snacks, sweets, and sweetened beverages made with fats and sugars derived from these policy-supported crops. Limiting or eliminating farm subsidies to commodity farmers is wrongly perceived as a quick fix to a complex agricultural system, evolved over decades, that promotes obesity. Yet this paper does set forth a series of policy recommendations that could help, including managing commodity crop oversupply and supporting farmers who produce more fruit and vegetables to build a healthier, more balanced agricultural policy.
Why Australia needs to define obesity as a chronic condition.
Opie, C A; Haines, H M; Ervin, K E; Glenister, K; Pierce, D
2017-05-23
In Australia people with a diagnosed chronic condition can be managed on unique funded care plans that allow the recruitment of a multidisciplinary team to assist in setting treatment goals and adequate follow up. In contrast to the World Health Organisation, the North American and European Medical Associations, the Australian Medical Association does not recognise obesity as a chronic condition, therefore excluding a diagnosis of obesity from qualifying for a structured and funded treatment plan. BODY: The Australian guidelines for management of Obesity in adults in Primary Care are structured around a five step process -the '5As': Ask & Assess, Advise, Assist and Arrange'. This article aims to identify the key challenges and successes associated with the '5As' approach, to better understand the reasons for the gap between the high Australian prevalence of overweight and obesity and an actual diagnosis and treatment plan for managing obesity. It argues that until the Australian health system follows the international lead and defines obesity as a chronic condition, the capacity for Australian doctors to diagnose and initiate structured treatment plans will remain limited and ineffective. Australian General Practitioners are limited in their ability manage obesity, as the current treatment guidelines only recognise obesity as a risk factor rather than a chronic condition.
Improving Childhood Obesity Treatment Using New Technologies: The ETIOBE System
Baños, Rosa. M; Cebolla, Ausias; Botella, Cristina; García-Palacios, Azucena; Oliver, Elia; Zaragoza, Irene; Alcaniz, Mariano
2011-01-01
Childhood obesity is an increasing public health problem in western culture. Sedentary lifestyles and an “obesogenic environment” are the main influences on children leading to an increase in obesity. The objective of this paper is to describe an e-health platform for the treatment and prevention of childhood obesity called ETIOBE. This e-health platform is an e-therapy system for the treatment of obesity, aimed at improving treatment adherence and promoting the mechanisms of self-control in patients, to obtain weight loss maintenance and to prevent relapse by establishing healthy lifestyle habits. ETIOBE is composed of three different applications, the Clinician Support System (CSS), the Home Support System (HSS) and the Mobile Support System (MSS). The use of new Information and Communication (ICT) technologies can help clinicians to improve the effectiveness of weight loss treatments, especially in the case of children, and to achieve designated treatment goals.

To evaluate the effects of web-based information on parental self-efficacy in managing obesity risk in preschoolers. The project included a literature review and the development and field testing of an information website that presented information on how to manage nine obesity risk factors for childhood obesity. Parents stated that they had no problems using the website, and 69% reported improved self-efficacy on at least two risk factors. Many parents access the Internet to obtain health information. A website that offers practical information on managing childhood obesity risk factors is a valuable resource for obesity prevention efforts. © 2014, Wiley Periodicals, Inc.

To assess whether health professionals' management or the organisation of care for overweight and obese people could be improved. We searched the specialised registers of the Cochrane Effective Practice and Organisation of Care Group (April 2000), the Cochrane Depression, Anxiety and Neurosis Group (August 1997), the Cochrane Diabetes Group (August 1997), the Cochrane Controlled Trials Register (September 1997), MEDLINE to April 2000, EMBASE to February 2000, Cinahl (1982 to February 2000), PsycLit (1974 to May 2000), Sigle (1980 to April 2000), Sociofile (1974 to October 1997), Dissertation Abstracts (1861 to January 1998), Conference Papers Index (1973 to January 1998), Resource Database in Continuing Medical Education.

Paediatric obesity, physical activity and the musculoskeletal system.
Shultz, S P; Anner, J; Hills, A P
2009-09-01
The current epidemic of paediatric obesity is consistent with a myriad of health-related comorbid conditions. Despite the higher prevalence of orthopaedic conditions in overweight children, a paucity of published research has considered the influence of these conditions on the ability to undertake physical activity. As physical activity participation is directly related to improvements in physical fitness, skeletal health and metabolic conditions, higher levels of physical activity are encouraged, and exercise is commonly prescribed in the treatment and management of childhood obesity. However, research has not correlated orthopaedic conditions, including the increased joint pain and discomfort that is commonly reported by overweight children, with decreases in physical activity. Research has confirmed that overweight children typically display a slower, more tentative walking pattern with increased forces to the hip, knee and ankle during 'normal' gait. This research, combined with anthropometric data indicating a higher prevalence of musculoskeletal malalignment in overweight children, suggests that such individuals are poorly equipped to undertake certain forms of physical activity. Concomitant increases in obesity and decreases in physical activity level strongly support the need to better understand the musculoskeletal factors associated with the performance of motor tasks by overweight and obese children.
Principles and Pitfalls in the Differential Diagnosis and Management of Childhood Obesities123

Obesity is currently the most prevalent chronic childhood disease in Western countries. It is one of the most frequent consultations in general pediatrics and is even more common in pediatric endocrinology. As might be predicted, the prevalence of obesity-associated comorbidities is also increasing in children and adolescents. It is widely accepted that this increase in obesity results from an imbalance between energy intake and expenditure, with an increase in positive energy balance being closely associated with the current lifestyle in Western countries. However, there is increasing evidence indicating that an individual’s genetic background is important in determining obesity risk. The physiologic mechanisms controlling appetite and energy expenditure are being revealed in part because of the identification of new causes of human monogenic, syndromic, and endocrine-related obesity. Thus, it is no longer appropriate to talk about obesity, but rather about “obesities” or “different diseases causing obesity,” because their pathophysiologic bases differ. Moreover, these obesities require different diagnostic and management approaches. The pediatrician must be aware of this issue and focus the clinical history and physical examination toward specific clinical signs and symptoms to better exploit the available diagnostic and therapeutic resources when facing a child with obesity. Genetic, genomic, and metabolomic studies are often necessary to obtain a more appropriate diagnosis. Cognitive behavioral therapy is fundamental in obese children. The identification of potential targets will hopefully result in new pharmacologic approaches for translational and personalized medicine for obesity in the near future. PMID:24829481

Obesity in childhood is one of the major health issues in pediatric health care today. As expected, the prevalence of obesity-related comorbidities has risen in parallel with that of obesity. Consultation regarding these concomitant diseases and subsequent management by subspecialists, including pediatric gastroenterologists, is now common and has resulted in obesity being recognized as a chronic disease requiring coordination of care. Although medications and even surgery may provide effective, though often temporary, treatments for obesity and its comorbidities, behavioral interventions addressing healthy dietary and physical activity habits remain a mainstay in the obesity treatment paradigm. Therefore, the issue of weight management must be addressed by both general practitioner and subspecialist alike. In this report, we review select aspects of pediatric obesity and obesity-related management issues because it relates in particular to the field of pediatric gastroenterology and hepatology.

Therapeutic alliance is a well-recognized predictor of patient outcomes within psychological therapy. It has not been applied to obesity interventions, and Bordin's theoretical framework shows particular relevance to the management of obesity in primary health care. This cross-sectional study of a weight management programme in general practice aimed to determine if therapeutic alliance was associated with patient outcomes. The Working Alliance Inventory short revised version (WAI-SR) was administered to 23 patients and 11 general practitioners (GPs) at the end of a 6-month weight management programme. Use of the WAI-SR indicated that the strength of therapeutic alliance varied between different patient-GP relationships in this pilot intervention. A robust therapeutic alliance was strongly associated with patient engagement in the weight management programme indicated by number of appointments. It was also associated with some general health and quality of life outcomes. These are promising results that require confirmation with larger studies in primary health care. The measurement of therapeutic alliance using the WAI-SR may predict patient attendance and outcomes in obesity interventions in primary healthcare settings. © 2016 World Obesity Federation.

Objectives To investigate what weight management interventions work for men, with which men, and under what circumstances. Design Realist synthesis of qualitative studies. Data sources Sensitive searches of 11 electronic databases from 1990 to 2012 supplemented by grey literature searches. Study selection Studies published between 1990 and 2012 reporting qualitative research with obese men, or obese men in contrast to obese women and lifestyle or drug weight management were included. The studies included men aged 16 years or over, with no upper age limit, with a mean or median body mass index of 30 kg/m2 in all settings. Results 22 studies were identified, including 5 qualitative studies linked to randomised controlled trials of weight maintenance interventions and 8 qualitative studies linked to non-randomised intervention studies, and 9 relevant UK-based qualitative studies not linked to any intervention. Health concerns and the perception that certain programmes had ‘worked’ for other men were the key factors that motivated men to engage with weight management programmes. Barriers to engagement and adherence with programmes included: men not problematising their weight until labelled ‘obese’; a lack of support for new food choices by friends and family, and reluctance to undertake extreme dieting. Retaining some autonomy over what is eaten; flexibility about treats and alcohol, and a focus on physical activity were attractive features of programmes. Group interventions, humour and social support facilitated attendance and adherence. Men were motivated to attend programmes in settings that were convenient, non-threatening and congruent with their masculine identities, but men were seldom involved in programme design. Conclusions Men's perspectives and preferences within the wider context of family, work and pleasure should be sought when designing weight management services. Qualitative research is needed with men to inform all aspects of intervention
Outcomes of weight management in obese pet dogs: what can we do better?
German, Alexander J
2016-08-01
Obesity is arguably the biggest health and welfare issue affecting pet dogs. Although successful weight loss has health benefits, current strategies are far from ideal. Many obese dogs that start a weight programme fail to lose weight, or subsequently regain the weight they have lost. Given that current weight loss strategies are not perfect, clinicians need to focus carefully on tailoring the programme, perhaps setting a pragmatic target for weight loss, so as to ensure the benefits are maximised. This review will summarise key findings from recent clinical research into pet obesity, and present a framework for improving success, by better tailoring weight management regimens and end points to the individual.

Peroxisome proliferator-activated receptor gamma (PPARγ) is a member of the nuclear receptor superfamily of ligand-inducible transcription factors that regulate adipogenesis, lipid metabolism, cell proliferation, inflammation and insulin sensitization. Abnormalities in PPARγ signaling have been associated with obesity, diabetes and cancer. The use of agonists to manage these diseases has been limited by their side effects. Accordingly, dual or pan agonists targeting the PPARα or PPARα and PPARδ, respectively, in addition to the PPARγ have been developed to overcome these side effects. This review details the shared PPARγ-dependent mechanisms between obesity-related cancers and diabetes and their potential therapeutic values. We performed a systematic literature search through pubmed, Scopus and google scholar for articles on PPARγ-dependent signaling in diabetes or cancer. There is growing co-occurrence of obesity-related cancers and diabetes, necessitating the use of effective therapies with the least amount of side effects for concurrent management of these diseases, by targeting potentially shared PPARγ-dependent mechanisms including abnormalities of the wnt/β-catenin, lysosomal acid lipase, inflammatory and cell cycle pathways, and the plasminogen activator system. Taking advantage of the multiple docking sites of the PPARγ and the pleiotropic nature of its signaling, structure-activity relationship and molecular docking studies have provided insights into designer PPARγ agonists or dual PPARα/γ agonists that modulate PPARγ signaling and negate side effects of full PPARγ agonists. Effective therapies, possibly devoid of side effects, for concurrent management of obesity-related cancers and diabetes can be developed through diligent structure-activity and molecular docking studies.

Obesity in pregnancy is rising and is associated with severe health consequences for both the mother and the child. There is an increasing international focus on guidelines to manage the clinical risks of maternal obesity, and for pregnancy weight management. However, passive dissemination of guidelines is not effective and more active strategies are required for effective guideline implementation into practice. Implementation of guidelines is a form of healthcare professional behaviour change, and therefore implementation strategies should be based on appropriate behaviour change theory. This systematic review aimed to identify the determinants of healthcare professionals' behaviours in relation to maternal obesity and weight management. Twenty-five studies were included. Data synthesis of the existing international qualitative and quantitative evidence base used the Theoretical Domains Framework to identify the barriers and facilitators to healthcare professionals' maternal obesity and weight management practice. The domains most frequently identified included 'knowledge', 'beliefs about consequences' and 'environmental context and resources'. Healthcare professionals' weight management practice had the most barriers compared with any other area of maternal obesity practice. The results of this review will be used to inform the development of an intervention to support healthcare professional behaviour change. © 2014 The Authors. obesity reviews © 2014 International Association for the Study of Obesity.

Childhood Obesity: Causes, Consequences, and Management.
Gurnani, Muskaan; Birken, Catherine; Hamilton, Jill
2015-08-01
One-third of North American children are overweight or obese. Pathologic obesity accounts for only a small percentage of these cases. The vast majority are the result of a complex interaction of genetic and hormonal, nutritional, physical activity, and physical and social environmental factors. Obesity increases the risk for various cardiometabolic, pulmonary, and psychosocial complications for children, which often continues into adulthood. Multidisciplinary care, focusing on family-centered behavior change, is an evidence-based, essential part of the treatment, along with pharmacologic and surgical options for more complex cases. Prevention and early intervention strategies are key to reversing the obesity epidemic. Copyright © 2015 Elsevier Inc. All rights reserved.
Overcoming extreme obesity with robotic surgery.

Obesity is often associated with endometrial cancer and has posed a challenge in surgical management. Complications such as wound breakdown, respiratory challenges, cardiac complications and difficult intubations are associated with obesity. For the patient with uterine cancer, surgery is necessary for staging, control of symptoms and cure. With the advent of the da Vinci(™) intuitive robot, alternative surgical options can now be offered to these patients. While surgery is the principal modality for the treatment and management of uterine cancer, the morbidly obese patient faces increased complications and longer postoperative recovery. As studied in the LAP2, comparable outcomes have been noted in laparotomy vs laparoscopic surgery. Recently, minimally invasive surgery has been refined with the advent of the da Vinci robotic system. Applying a minimally invasive technique further enhanced with the da Vinci robotic system, a total laparoscopic hysterectomy with bilateral salpingo-oophorectomy was performed on a patient with a BMI of 98. A 35 year-old G0 woman with a BMI of 98 presented with heavy vaginal bleeding and anaemia. She was diagnosed with endometrioid adenocarcinoma of the uterus, FIGO grade 1. She was treated with a robotically assisted total laparoscopic hysterectomy and bilateral salpingo-oophorectomy. Her postoperative course was uncomplicated and she was discharged home on post-operative day 1. Since obesity is a significant risk factor for endometrial cancer and the prevalence of obesity is increasing, developing surgical techniques to appropriately manage these patients is important. Minimally invasive surgery, specifically with robotic assistance, has increased the possibilities of performing minimally invasive surgery in morbidly obese women. It allows navigation around anatomical barriers and decreases the fatigue experienced by the surgeons. With the increasing obesity of our population and the high prevalence of uterine cancer, further
Challenges in the Management of Geriatric Obesity in High Risk Populations

The global prevalence of obesity in the older adult population is growing, an increasing concern in both the developed and developing countries of the world. The study of geriatric obesity and its management is a relatively new area of research, especially pertaining to those with elevated health risks. This review characterizes the state of science for this “fat and frail” population and identifies the many gaps in knowledge where future study is urgently needed. In community dwelling older adults, opportunities to improve both body weight and nutritional status are hampered by inadequate programs to identify and treat obesity, but where support programs exist, there are proven benefits. Nutritional status of the hospitalized older adult should be optimized to overcome the stressors of chronic disease, acute illness, and/or surgery. The least restrictive diets tailored to individual preferences while meeting each patient’s nutritional needs will facilitate the energy required for mobility, respiratory sufficiency, immunocompentence, and wound healing. Complications of care due to obesity in the nursing home setting, especially in those with advanced physical and mental disabilities, are becoming more ubiquitous; in almost all of these situations, weight stability is advocated, as some evidence links weight loss with increased mortality. High quality interdisciplinary studies in a variety of settings are needed to identify standards of care and effective treatments for the most vulnerable obese older adults. PMID:27153084

Approximately 36% of adult women in the United States are obese. Although obesity affects women similarly to men in terms of prevalence, there seem to be gender-specific differences in the pathophysiology, clinical manifestations, and treatment of obesity. Obesity is linked to comorbid diseases involving multiple organ systems, including the gastrointestinal tract, like gastroesophageal reflux disease, fatty liver disease, and gallstones. This article focuses on obesity in women, specifically the impact of obesity on gastrointestinal diseases and reproductive health, as well as the treatment of obesity in women.

Obesity, hypertension, and chronic kidney disease
Hall, Michael E; do Carmo, Jussara M; da Silva, Alexandre A; Juncos, Luis A; Wang, Zhen; Hall, John E
2014-01-01
Obesity is a major risk factor for essential hypertension, diabetes, and other comorbid conditions that contribute to development of chronic kidney disease. Obesity raises blood pressure by increasing renal tubular sodium reabsorption, impairing pressure natriuresis, and causing volume expansion via activation of the sympathetic nervous system and renin–angiotensin–aldosterone system and by physical compression of the kidneys, especially when there is increased visceral adiposity. Other factors such as inflammation, oxidative stress, and lipotoxicity may also contribute to obesity-mediated hypertension and renal dysfunction. Initially, obesity causes renal vasodilation and glomerular hyperfiltration, which act as compensatory mechanisms to maintain sodium balance despite increased tubular reabsorption. However, these compensations, along with increased arterial pressure and metabolic abnormalities, may ultimately lead to glomerular injury and initiate a slowly developing vicious cycle that exacerbates hypertension and worsens renal injury. Body weight reduction, via caloric restriction and increased physical activity, is an important first step for management of obesity, hypertension, and chronic kidney disease. However, this strategy may not be effective in producing long-term weight loss or in preventing cardiorenal and metabolic consequences in many obese patients. The majority of obese patients require medical therapy for obesity-associated hypertension, metabolic disorders, and renal disease, and morbidly obese patients may require surgical interventions to produce sustained weight loss.

Abstract The Adolescents Surveillance System for Obesity prevention (ASSO) Project aimed at developing standardized and web-based tools for collecting data on adolescents’ obesity and its potential determinants. This has been implemented and piloted in the local area of Palermo city, Italy. The aim of the present study is to provide an overview of the Project's design, implementation, and evaluation, highlighting all the aspects for a potential scale-up of the surveillance system on the whole national territory and abroad, as a sustainable and effective source of data. The overall structure and management, the ASSO-toolkit, the ASSO-NutFit software, and all developed and used procedures for recruiting, training, and data collecting/analyzing are addressed. An interim evaluation has been performed through a feasibility study; a final Project evaluation has been performed reporting the Strengths, Weaknesses, Opportunities, and Threats (SWOT) and the attributes that a surveillance system should have. This article provides a detailed overview of the Project and highlights that ASSO can be considered a valid, logical, coherent, efficient, and sustainable surveillance system that is consistent with countries’ needs and priorities. The system developed by the ASSO Project provides high-quality data and complies with several characteristics typical of a suitable surveillance system. It has a potential of being adopted within the National Health Service and other countries’ Health Services for monitoring adolescents’ obesity and its determinants, such as food intakes, behaviors, physical activity, and fitness profiles.

This paper explores how system-wide approaches to obesity prevention were 'theorised' and translated into practice in the 'Healthy Towns' programme implemented in nine areas in England. Semi-structured interviews with 20 informants, purposively selected to represent national and local programme development, management and delivery were undertaken. Results suggest that informants articulated a theoretical understanding of a system-wide approach to obesity prevention, but simplifying this complex task in the context of uncertainty over programme aims and objectives, and absence of a clear direction from the central government, resulted in local programmes relying on traditional multi-component approaches to programme delivery. The development of clear, practical guidance on implementation should form a central part of future system-wide approaches to obesity prevention. Copyright © 2014 Elsevier Ltd. All rights reserved.

The aim of this study is to determine opportunities and barriers regarding the management of overweight and obese children in daily practice, and to show the value of using focus groups when developing an action plan for childhood overweight management in a local context. Seven focus groups and four semi-structured interviews were conducted with 29 professionals from nine different care disciplines and 7 parents of overweight and obese children aged 4-19 years. After thorough analysis of the focus groups, issues concerning finding the most appropriate care and realising a long-term weight management in daily practice have become clear. Some examples of these issues are: lack of awareness, reluctance to discuss and refer, mutual cooperation, contradictory advice and expectations of treatment and lack of effective support strategies. Focus groups deliver important information on local issues that are important for the development and implementation of a childhood overweight management action plan. And, besides delivering necessary information, focus groups lead to an increased awareness and willingness to improve childhood overweight management in a local context. Copyright © 2012 S.

The incidence of obesity has acquired an epidemic proportion throughout the globe. As a result, increasing number of obese patients is being presented to critical care units for various indications. The attending intensivist has to face numerous challenges during management of such patients. Almost all the organ systems are affected by the impact of obesity either directly or indirectly. The degree of obesity and its prolong duration are the main factors which determine the harmful effect of obesity on human body. The present article reviews few of the important clinical and critical care concerns in critically ill obese patients. PMID:23087857

A multidisciplinary Tier 3 weight management service in primary care recruited patients with a body mass index ≥40 kg·m(-2) , or 30 kg·m(-2) with obesity-related co-morbidity to a 1-year programme. A cohort of 230 participants was recruited and evaluated using the National Obesity Observatory Standard Evaluation Framework. The primary outcome was weight loss of at least 5% of baseline weight at 12 months. Diet was assessed using the two-item food frequency questionnaire, activity using the General Practice Physical Activity questionnaire and quality of life using the EuroQol-5D-5L questionnaire. A focus group explored the participants' experiences. Baseline mean weight was 124.4 kg and mean body mass index was 44.1 kg·m(-2) . A total of 102 participants achieved 5% weight loss at 12 months. The mean weight loss was 10.2 kg among the 117 participants who completed the 12-month programme. Baseline observation carried forward analysis gave a mean weight loss of 5.9 kg at 12 months. Fruit and vegetable intake, activity level and quality of life all improved. The dropout rate was 14.3% at 6 months and 45.1% at 1 year. Focus group participants described high levels of satisfaction. It was possible to deliver a Tier 3 weight management service for obese patients with complex co-morbidity in a primary care setting with a full multidisciplinary team, which obtained good health outcomes compared with existing services. © 2014 The Authors.

Community health centers (CHCs) seek effective strategies to address obesity. MidWest Clinicians’ Network partnered with [an academic medical center] to test feasibility of a weight management quality improvement (QI) collaborative. MidWest Clinicians’ Network members expressed interest in an obesity QI program. This pilot study aimed to determine whether the QI model can be feasibly implemented with limited resources at CHCs to improve weight management programs. Five health centers with weight management programs enrolled with CHC staff as primary study participants; this study did not attempt to measure patient outcomes. Participants attended learning sessions and monthly conference calls to build QI skills and share best practices. Tailored coaching addressed local needs. Topics rated most valuable were patient recruitment/retention strategies, QI techniques, evidence-based weight management, motivational interviewing. Challenges included garnering provider support, high staff turnover, and difficulty tracking patient-level data. This paper reports practical lessons about implementing a weight management QI collaborative in CHCs. PMID:23727964
Greasing the Wheels of Managing Overweight and Obesity with Omega-3 Fatty Acids

The epidemic of overweight and obesity around the world and in the US is a major public health challenge, with 1.5 billion overweight and obese adults worldwide, and 68% of US adults and 31% of US children and adolescents overweight or obese. Obesity leads to serious health consequences, including an increased risk of type 2 diabetes mellitus and heart disease. Current preventive and medical treatments include lifestyle modification, medication, and bariatric surgery in extreme cases; however, they are either not very efficacious or are very expensive. Obesity is a complex condition involving the dysregulation of several organ systems and molecular pathways, including adipose tissue, the pancreas, the gastrointestinal tract, and the CNS. The role of the CNS in obesity is receiving more attention as obesity rates rise and treatments continue to fail. While the role of the hypothalamus in regulation of appetite and food intake has long been recognized, the roles of the CNS reward systems are beginning to be examined as the role of environmental influences on energy balance are explored. Omega-3 polyunsaturated fatty acids are essential nutrients that play a beneficial role in several disease processes due to their anti-inflammatory effects, modulation of lipids, and effects on the CNS. Omega-3 fatty acids, specifically EPA and DHA, have shown promising preliminary results in animal and human studies in the prevention and treatment of obesity. Given their effects on many of the pathways involved in obesity, and specifically in the endocannabinoid and mesocorticolimbic pathways, we hypothesize that EPA and DHA supplementation in populations can reduce the reward associated with food, thereby reduce appetite and food intake, and ultimately contribute to the prevention or reduction of obesity. If these fatty acids do harbor such potential, their supplementation in many parts of the world may hold great promise in reducing the global burden of obesity. PMID:21981905

To achieve WHO's target to halt the rise in obesity and diabetes, dramatic actions are needed to improve the healthiness of food environments. Substantial debate surrounds who is responsible for delivering effective actions and what, specifically, these actions should entail. Arguments are often reduced to a debate between individual and collective responsibilities, and between hard regulatory or fiscal interventions and soft voluntary, education-based approaches. Genuine progress lies beyond the impasse of these entrenched dichotomies. We argue for a strengthening of accountability systems across all actors to substantially improve performance on obesity reduction. In view of the industry opposition and government reluctance to regulate for healthier food environments, quasiregulatory approaches might achieve progress. A four step accountability framework (take the account, share the account, hold to account, and respond to the account) is proposed. The framework identifies multiple levers for change, including quasiregulatory and other approaches that involve government-specified and government-monitored progress of private sector performance, government procurement mechanisms, improved transparency, monitoring of actions, and management of conflicts of interest. Strengthened accountability systems would support government leadership and stewardship, constrain the influence of private sector actors with major conflicts of interest on public policy development, and reinforce the engagement of civil society in creating demand for healthy food environments and in monitoring progress towards obesity action objectives.

There is an increased prevalence of obesity and the metabolic syndrome (MS) among South Asians. The phenotypes of obesity and body fat distribution are different in South Asians; they have high body fat, intra-abdominal and subcutaneous fat and fatty liver at a lower body mass index compared to white Caucasians; this has led to the frequent occurrence of morbidities related to a higher magnitude of adiposity [e.g. type 2 diabetes mellitus (T2DM), hypertension (HTN) and dyslipidemia]. The increasing prevalence of obesity and related diseases in the South Asian population requires aggressive lifestyle management including diet, physical activity and, sometimes, drugs. For therapeutic interventions, several drugs can be used either as mono- or combination therapy. Drugs like orlistat, which is used for the management of obesity, also reduce the risk of T2DM. Similarly, HMG CoA reductase inhibitors decrease low-density-lipoprotein cholesterol levels and reduce the risk of cardiovascular diseases. However, some drugs used for the treatment of HTN (e.g. β-blockers) may increase the risk of hyperglycemia and therefore need to be used with caution. Finally, to prevent obesity, MS and T2DM among South Asians, it is particularly important to effectively implement and strengthen population-based primary prevention strategies. © 2015 Nestec Ltd., Vevey/S.

The Edmonton Obesity Staging System for Pediatrics (EOSS-P) is a useful tool, delineating different obesity severity tiers associated with distinct treatment barriers. The aim of the study was to apply the EOSS-P on a Greek pediatric cohort and assess risk factors associated with each stage, compared to normal weight controls. A total of 361 children (2-14 years old), outpatients of an Athenian hospital, participated in this case-control study by forming two groups: the obese (n = 203) and the normoweight controls (n = 158). Anthropometry, blood pressure, blood and biochemical markers, comorbidities and obesogenic lifestyle parameters were recorded and the EOSS-P was applied. Validation of EOSS-P stages was conducted by juxtaposing them with IOTF-defined weight status. Obesogenic risk factors' analysis was conducted by constructing gender-and-age-adjusted (GA) and multivariate logistic models. The majority of obese children were stratified at stage 1 (46.0%), 17.0% were on stage 0, and 37.0% on stage 2. The validation analysis revealed that EOSS-P stages greater than 0 were associated with diastolic blood pressure and levels of glucose, cholesterol, LDL and ALT. Reduced obesity odds were observed among children playing outdoors and increased odds for every screen time hour, both in the GA and in the multivariate analyses (all P < 0.05). Although participation in sports > 2 times/week was associated with reduced obesity odds in the GA analysis (OR = 0.57, 95% CI = 0.33-0.98, P linear = 0.047), it lost its significance in the multivariate analysis (P linear = 0.145). Analogous results were recorded in the analyses of the abovementioned physical activity risk factors for the EOSS-P stages. Linear relationships were observed for fast-food consumption and IOTF-defined obesity and higher than 0 EOSS-P stages. Parental obesity status was associated with all EOSS-P stages and IOTF-defined obesity status. Few outpatients were healthy obese (stage 0), while

Complementary therapies may increase the success rate of weight loss via a calorie-restricted diet. Acupuncture is a popular complementary therapy for obesity management. To our knowledge, no studies have summarised the effects of laser acupuncture (LA) on obesity. To evaluate the efficacy of LA, in particular with respect to its impact on anthropometric features and appetite in obese adults, by conducting a systematic review of previous clinical trials. We searched PubMed/Medline, Scopus, Web of Science, the Cochrane Library, Embase and Google Scholar electronic databases for papers published through October 2016. All clinical trials in English containing either anthropometric indices or appetite parameters were included. Two reviewers independently examined studies based on a predefined form for data extraction and the Jadad scale for quality assessment in order to minimise bias throughout the evaluation. After screening the papers, seven clinical trials met the criteria and were included in the systematic review. Positive effects of LA therapy were seen in body weight (n=3), body mass index (n=5), waist circumference (n=4), hip circumference (n=3), waist to hip ratio (n=4) and % fat mass (n=3). Appetite parameters were reported in one study, which showed that LA can reduce appetite and increase the sensation of feeling full. Although some studies have indicated beneficial effects for LA on obesity, the lack of evidence with high methodological quality made it impossible to reach a definitive conclusion about the efficacy of LA for obesity management. Further high-quality, randomised, sham-controlled clinical trials with a larger sample size are needed to shed light on the efficacy of LA for obesity management and weight maintenance. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The endocannabinoid system: a new pharmacological target for obesity treatment?
Hu, Jia; Zhu, Chao; Huang, Mao
2009-06-01
Being a great threaten for human health, obesity has become a pandemic chronic disease. There have been several therapeutic treatments for this social health issue, including diet and exercise therapy, medication and surgery, among which the diet is still the most common way. However, none of these therapeutic measures available is ideal, making it necessary to find an effective medical treatment. The endocannabinoid system, which is well known for its contributions in certain mental processes such as relaxation, amelioration of pain and anxiety, and sedation initiation, has been recently reported to play an essential role in regulating appetite and metabolism to maintain energy balance, leading to the belief that endocannabinoid system is closely related to obesity. This new discovery deepens our understanding of obesity, and provides us with a new direction for clinical obesity treatment. Rimonabant is an antagonist for CB1, and has entered the market in some countries. However, although effective as an anti-obesity drug, rimonabant also causes obviously adverse side-effects, thus is being doubted and denied for medical usage.

The aim of this research into 'self-management' was to determine to what extent respondents were aware of their status as overweight or obese. For respondents who indicated that they were overweight or obese, the goal was to determine whether they tried to lose weight, what steps they took to control their, and what specific methods they used. Information was collected using semi-structured interviews from May 31, 2014, to January 30, 2015. Data processing was performed using statistical analysis of the social data SASDM 01/04/10 software. The total study group consisted of 600 respondents, including 302 from the Roma minority, and 298 from the non-Roma majority population (control group). Respondents were selected specifically from South Bohemia Region of the Czech Republic. The sample from the Roma minority was constructed using the snowball method (Snowball Sampling). The control sample of non-Roma was selected through quota sampling. The results indicate that the respondents from both the Roma minority and the non-Roma control group generally recognized when they were overweight or obese, or they were aware of it to a much lesser extent than objective indicators revealed. More than two thirds of the respondents who admitted they were overweight or obese (N = 143) reported that they had suffered from overweight or obesity since they were young adults. Significantly more members of the majority population had tried to lose weight using self-management, whereas the level of effort was significantly less among members of the Roma minority (P = 0). Nevertheless, Roma respondents significantly more often reported (P < 0.01) that they had agreed on a specific weight loss plan with a doctor. The results of our research show that in the context of prevention, it is important to promote self-managed skills, habits and other characteristics that can play an important role in the prevention and treatment of obesity and overweight.

Obesity may reduce diagnostic accuracy of B-type natriuretic peptide (BNP) and affect long-term outcome. This study evaluated patients included in the BASEL study (N = 452). We compared BNP levels in patients with (n = 86) and without (n = 366) obesity (body mass index <30 and >30 kg/m(2)) and determined sensitivities and specificities of BNP in both patient groups by receiver-operating characteristic analysis. Impact of BNP measurements on patient management and outcome in obesity, as well as 360-day mortality, was assessed. The BNP levels were lower in obese patients (172 pg/mL [interquartile range 31-515] vs 306 [interquartile range 75-1,040]). The optimal BNP cut-point to detect heart failure was 182 pg/mL in obese patients and 298 pg/mL nonobese patients. Obese patients had lower in-hospital mortality (3.5% vs 8.5%, P = .045) and 360-day mortality (15% vs 30%, P = .001). In obese patients, the determination of BNP levels reduced time to initiation of the appropriate treatment (96 +/- 98 vs 176 +/- 230, P < .05) without impacting other end points. Adjustment of BNP values in the assessment of obese patients presenting with acute dyspnea seems necessary to improve diagnostic accuracy and patient management. Obese patients had half the short- and long-term mortality of nonobese patients, independent of their final discharge diagnosis.

Building self-esteem in overweight adolescents is key to long-term weight management; yet, self-esteem is rarely a key outcome of adolescent weight management interventions. This systematic review investigates the impact of multicomponent weight management interventions on self-esteem in overweight and obese adolescents. Six databases were searched in December 2014. Eligible studies met the following criteria: (1) randomized controlled trial, (2) overweight or obese participants, (3) adolescents (10-19 years), (4) multicomponent weight management intervention, (5) reported self-esteem and weight changes. Thirteen studies with 1,157 overweight or obese adolescents, aged 10-19 years, were included. Meta-analyses showed no significant change in self-esteem (0.27 [-0.04, 0.59]), but body mass index z -score reduced following intervention (-0.17 [-0.22, -0.11]). The lack of change in self-esteem suggests weight loss alone is insufficient to improve self-esteem. Multicomponent weight management interventions require a specific focus on self-esteem to improve this outcome in overweight and obese adolescents. © The Author 2017.

Naltrexone ER/Bupropion ER: A Review in Obesity Management.
Greig, Sarah L; Keating, Gillian M
2015-07-01
Oral naltrexone extended-release/bupropion extended-release (naltrexone ER/bupropion ER; Contrave(®), Mysimba(™)) is available as an adjunct to a reduced-calorie diet and increased physical activity in adults with an initial body mass index (BMI) of ≥ 30 kg/m(2) (i.e. obese) or a BMI of ≥ 27 kg/m(2) (i.e. overweight) in the presence of at least one bodyweight-related comorbidity, such as type 2 diabetes mellitus, hypertension or dyslipidaemia. In 56-week phase III trials in these patient populations, oral naltrexone ER/bupropion ER 32/360 mg/day was significantly more effective than placebo with regard to percentage bodyweight reductions from baseline and the proportion of patients who achieved bodyweight reductions of ≥ 5 and ≥ 10%. Significantly greater improvements in several cardiometabolic risk factors were also observed with naltrexone ER/bupropion ER versus placebo, as well as greater improvements in glycated haemoglobin levels in obese or overweight adults with type 2 diabetes. Naltrexone ER/bupropion ER was generally well tolerated in phase III trials, with nausea being the most common adverse event. Thus, naltrexone ER/bupropion ER 32/360 mg/day as an adjunct to a reduced-calorie diet and increased physical activity, is an effective and well tolerated option for chronic bodyweight management in obese adults or overweight adults with at least one bodyweight-related comorbidity.

Over the last four decades, as the rates of obesity have increased, so have the challenges associated with its anesthetic management. In the present review, we discuss perioperative anesthesia management issues that are modifiable by the early involvement of the surgical team. We sum up available evidence or expert opinion on issues like patient positioning, postoperative analgesia, and the effect of continuous positive airway pressure (CPAP) ventilation on surgical anastomosis. We also address established predictors of higher perioperative risk and suggest possible management strategies and concerns of obese patients undergoing same day procedures. Finally, a generalized pharmacological model relevant to altered pharmacokinetics in these patients is presented.

Obesity has been linked to morbidity and mortality through increased risk for many chronic diseases. Endothelin (EDN) system has been related to endothelial function but it can be involved in lipid metabolism regulation: Receptor type A (EDNRA) activates lipolysis in adipocytes, the two endothelin receptors mediate arsenic-stimulated adipocyte dysfunction, and endothelin system can regulate adiposity by modulating adiponectin activity in different situations and, therefore, influence obesity development. The aim of the present study was to analyze if single nucleotide polymorphisms (SNPs) in the EDN system could be associated with human obesity. We analyzed two samples of general-population-based studies from two different regions of Spain: the VALCAR Study, 468 subjects from the area of Valencia, and the Hortega Study, 1502 subjects from the area of Valladolid. Eighteen SNPs throughout five genes were analyzed using SNPlex. We found associations for two polymorphisms of the EDNRB gene which codifies for EDN receptor type B. Genotypes AG and AA of the rs5351 were associated with a lower risk for obesity in the VALCAR sample (p=0.048, OR=0.63) and in the Hortega sample (p=0.001, OR=0.62). Moreover, in the rs3759475 polymorphism, genotypes CT and TT were also associated with lower risk for obesity in the Hortega sample (p=0.0037, OR=0.66) and in the VALCAR sample we found the same tendency (p=0.12, OR=0.70). Furthermore, upon studying the pooled population, we found a stronger association with obesity (p=0.0001, OR=0.61 and p=0.0008, OR=0.66 for rs5351 and rs3759475, respectively). Regarding plasma arsenic levels, we have found a positive association for the two SNPs studied with obesity risk in individuals with higher arsenic levels in plasma: rs5351 (p=0.0054, OR=0.51) and rs3759475 (p=0.009, OR=0.53). Our results support the hypothesis that polymorphisms of the EDNRB gene may influence the susceptibility to obesity and can interact with plasma arsenic levels.

Asthma is a chronic disorder affecting millions of people worldwide. The prevalence of asthma is around 300 million and is expected to increase another 100 million by 2025. Obesity, on the other hand, also affects a large number of individuals. Overweight in adults is defined when body mass index (BMI) is between 25 to 30 kg/m2 and obesity when the BMI >30 kg/m2. It has been a matter of interest for researchers to find a relation between these two conditions. This knowledge will provide a new insight into the management of both conditions. At present, obese asthma patients may be considered a special category and it is important to assess the impact of management of obesity on asthma symptoms. PMID:23661915
3. Management and prevention of obesity and its complications in children and adolescents.
Batch, Jennifer A; Baur, Louise A

Obesity in children and adolescents has reached alarming levels--20%-25% of children and adolescents are overweight or obese, and 4.9% of boys and 5.4% of girls are obese. Rates of obesity have increased significantly in Australia from 1985 to 1995, with the prevalence of overweight doubling and obesity trebling. Body mass index (related to reference standards for age and sex) is recommended as a practical measure of overweight and obesity in children, and is used in monitoring individual progress in clinical practice. Obesity in childhood and adolescence may be associated with a range of medical and psychological complications, and can predispose individuals to serious health problems in adult life, including type 2 diabetes, hypertension, dyslipidaemia and non-alcoholic steatohepatitis. Obesity interventions for which there is some evidence include family support, a developmentally appropriate approach, long-term behaviour modification, dietary change, and increased physical activity and decreased sedentary behaviour. Prevention of obesity in children and adolescents requires a range of strategies involving changes in both the microenvironment (eg, housing, neighbourhoods, recreational opportunities) and the macroenvironment (eg, food marketing, transport systems, urban planning).

To explore the perceived barriers, resources, and training needs of rural primary care providers in relation to implementing the American Medical Association Expert Committee recommendations for assessment, treatment, and prevention of childhood obesity. In-depth interviews were conducted with 13 rural primary care providers in Oregon. Transcribed interviews were thematically coded. Barriers to addressing childhood obesity fell into 5 categories: barriers related to the practice (time constraints, lack of reimbursement, few opportunities to detect obesity), the clinician (limited knowledge), the family/patient (family lifestyle and lack of parent motivation to change, low family income and lack of health insurance, sensitivity of the issue), the community (lack of pediatric subspecialists and multidisciplinary/tertiary care services, few community resources), and the broader sociocultural environment (sociocultural influences, high prevalence of childhood obesity). There were very few clinic and community resources to assist clinicians in addressing weight issues. Clinicians had received little previous training relevant to childhood obesity, and they expressed an interest in several topics. Rural primary care providers face extensive barriers in relation to implementing recommended practices for assessment, treatment, and prevention of childhood obesity. Particularly problematic is the lack of local and regional resources. Employing nurses to provide case management and behavior counseling, group visits, and telehealth and other technological communications are strategies that could improve the management of childhood obesity in rural primary care settings. © 2013 National Rural Health Association.

Stress and negative emotions have been shown to be critical factors in inducing overeating as a form of maladaptive coping in obese people. The present study aimed to evaluate the efficacy of an 8-week stress management programme that includes progressive muscle relaxation (PMR) and diaphragmatic breathing on weight loss and eating behaviour in a sample of overweight and obese women who started a weight-loss programme. A total of 34 women with a mean (SD) body mass index of 38.17 (7.19) kg m(-) ² and mean (SD) age 47.35 (11.64) years were recruited from the outpatients Obesity Clinic of a public hospital in Athens. Participants were randomly assigned into a Stress Management (SM) and a control group. Anthropometric measurements were taken before and after the intervention, and the participants completed the following questionnaires: Dutch Eating Behaviour Questionnaire (DEBQ), Eating Attitudes Test (Eat-26), Health Locus of Control (HLC) and Perceived Stress Scale (PSS) before and after the intervention. The findings indicated a significant improvement in weight loss in the SM group [4.44 (0.83) kg] after intervention compared to the control group [1.38 (0.78) kg] (P < 0.05). A higher restrained eating behaviour was observed in the SM group after intervention compared to the control group, although there was no significant difference in perceived stress levels. The intervention group showed greater weight reduction, possibly because of the stress management programme, and a greater dietary restraint was demonstrated by them compared to the control group. It is likely that stress management could facilitate weight loss in obese women; however, more studies are needed to confirm this hypothesis. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

Childhood obesity has become an important public health problem in Thailand. This study aimed to determine the relationship between self discipline and obesity in Bangkok school children. A case control study was conducted. 140 cases (obese children) and 140 controls (normal weight children) were randomly chosen from grades 4-6 students in 4 Bangkok public schools. Questionnaire responses regarding general characteristics and child self-discipline were obtained from children and their parents. Self discipline in eating habits, money management and time management were reported at significantly lower levels among the obese group (p < 0.05). After controlling all other variables, it was revealed that the ranking of factors associated with obesity by adjusted odds ratio (OR) were low self-discipline in managing expenses (3.1), poor home environment (3.0,), moderate self-discipline in time management (2.9), television viewing time ≥2 hours/day (2.6), an obese father (2.2), and an obese mother (1.9). It was recommended that parents and teachers participate in child self-discipline guidance, particularly with regard to eating habits, money management and time management in a supportive environment that both facilitates prevention of obesity and simultaneously develops a child's personal control.

Childhood obesity and insulin resistance: how should it be managed?
Ho, Mandy; Garnett, Sarah P; Baur, Louise A
2014-12-01
Concomitant with the rise in global pediatric obesity in the past decades, there has been a significant increase in the number of children and adolescents with clinical signs of insulin resistance. Given insulin resistance is the important link between obesity and the associated metabolic abnormalities and cardiovascular risk, clinicians should be aware of high risk groups and treatment options. As there is no universally accepted biochemical definition of insulin resistance in children and adolescents, identification and diagnosis of insulin resistance usually relies on clinical features such as acanthosis nigricans, polycystic ovary syndrome, hypertension, dyslipidemia, and nonalcoholic fatty liver disease. Treatment for reducing insulin resistance and other obesity-associated comorbidities should focus on changes in health behaviors to achieve effective weight management. Lifestyle interventions incorporating dietary change, increased physical activity, and decreased sedentary behaviors, with the involvement of family and adoption of a developmentally appropriate approach, should be used as the first line treatment. Current evidence suggests that the primary objective of dietary interventions should be to reduce total energy intake and a combination of aerobic and resistance training should be encouraged. Metformin can be used in conjunction with a lifestyle intervention program in obese adolescents with clinical insulin resistance to achieve weight loss and to improve insulin sensitivity. Ongoing evaluation and research are required to explore optimal protocol and long-term effectiveness of lifestyle interventions, as well as to determine whether the improvements in insulin sensitivity induced by lifestyle interventions and weight loss will lead to a clinical benefit including reduced cardiovascular morbidity and mortality.

An uncontrolled study was conducted to evaluate the effects of a group-based program on weight control, metabolic profiles, and obesity-related complications in obese youth. The program consisted of an initial in-patient session and five group sessions, one, two, three, six, and nine months into the study, providing participants and their parents with information about the consequences of obesity and lifestyle modifications. The severity of obesity and obesity-related complications were evaluated at baseline and 12 months after the intervention. The participants' and their parents' perceptions of the program were assessed. Of the obese youth recruited (n=126), 115 completed the study. Their percentage weight for height and percentage body fat decreased significantly (both p<0.001), and their insulin resistance, lipid profiles, and transaminases levels improved (all p<0.01). The prevalence of prediabetes, dyslipidemia, and elevated transaminases decreased significantly (all p<0.05). The participants and their parents perceived the program as valuable. A group-based program is effective in managing childhood obesity, improving metabolic profiles, and alleviating certain obesity-related complications. A group-based program that provides education and raises the awareness of obese children and their parents about the consequences of obesity is an effective model for treating childhood obesity.

Clinicians vary significantly in their adherence to clinical guidelines for overweight/obesity. This study assessed the impact of electronic health record-based clinical decision support in improving the diagnosis and management of pediatric obesity. The study team programmed a point-of-care alert linked to a checklist and standardized documentation templates to appear during health maintenance visits for overweight/obese children in an outpatient teaching clinic and compared outcomes through medical record reviews of 574 (287 control and 287 intervention) visits. The results demonstrated a statistically significant increase in the diagnosis of overweight/obesity, scheduling of follow-up appointments, frequency of ordering recommended laboratory investigations, and assessment and counseling for nutrition and physical activity. Although clinical guideline adherence increased significantly, it was far from universal. It is unknown if modest improvements in adherence to clinical guidelines translate to improvements in children's health. However, this intervention was relatively easy to implement and produced measurable improvements in health care delivery. © 2014 by the American College of Medical Quality.
An Evaluation of the Identification and Management of Overweight and Obesity in a Pediatric Clinic.
Reyes, Imelda
2015-01-01
With the rise in overweight and obesity in children, it is imperative for health care providers to routinely address appropriate body mass index for children during primary care visits. The purposes of this project were to determine if overweight and obese children are accurately being identified and to evaluate provider adherence to American Academy of Pediatrics guidelines for the management of obesity. A retrospective chart review was completed for all children ages 2, 6, and 10 years who presented for a well-child visit from January 1, 2011, through June 30, 2011. Based on a review of 255 charts, 21.6% of patients were overweight and 18.4% were obese according to standards of the Centers for Disease Control and Prevention. Of these children, 34% were properly documented as being either overweight or obese, and documentation was lacking for the remaining 66%. Of the children correctly identified as being overweight or obese, only 11% and 26%, respectively, were counseled on therapeutic lifestyle changes, including diet and exercise. This review provides evidence that providers have opportunities to intervene early with well-child examinations and that providers have great room for improvement on counseling overweight and obese children.

The abnormal or excessive fat accumulation that impairs health is one of the criteria that fulfills obesity. According to epidemiological data, obesity has become a worldwide public health problem that in turn would trigger additional pathologies such as cardiorespiratory dysfunctions, cancer, gastrointestinal disturbances, depression, sleep disorders, just to mention a few. Then, the search for a therapeutical intervention aimed to prevent and manage obesity has been the focus of study during the last years. As one can assume, the increased prevalence of obesity has translated to search of efficient pharmaceuticals designed to manage this health issue. However, to further complicate the scenario, scientific literature has described that obesity is the result of interaction between multiple events. Therefore, pharmacological approaches have faced a serious challenge for develop the adequate treatment. Here, we argue that a wide range of non-pharmacological/invasive techniques can be used to manage obesity, such as diets, cognitive behavioral interventions, exercise and transcranial direct current stimulation. Combining these techniques may allow improving quality of life of obese patients. Copyright © 2018 European Society for Clinical Nutrition and Metabolism. Published by Elsevier Ltd.

The aim of this research is to examine perceptions of those with comorbid chronic pain and obesity regarding their experience of comorbidity management in primary care settings. Chronic pain and obesity are common comorbidities frequently managed in primary care settings. Evidence suggests individuals with this comorbidity may be at risk for suboptimal clinical interactions; however, treatment experiences and preferences of those with comorbid chronic pain and obesity have received little attention. Semi-structured interviews conducted with 30 primary care patients with mean body mass index=36.8 and comorbid persistent pain. The constant comparative method was used to analyze data. Participants discussed frustration with a perceived lack of information tailored to their needs and a desire for a personalized treatment experience. Participants found available medical approaches unsatisfying and sought a more holistic approach to management. Discussions also focused around the need for providers to initiate efforts at education and motivation enhancement and to show concern for and understanding of the unique difficulties associated with comorbidity. Findings suggest providers should engage in integrated communication regarding weight and pain, targeting this multimorbidity using methods aligned with priorities discussed by patients.
Managing temptation in obesity treatment: a neurobehavioral model of intervention strategies
Appelhans, Bradley M; French, Simone A; Pagoto, Sherry L; Sherwood, Nancy E
2015-01-01
Weight loss outcomes in lifestyle interventions for obesity are primarily a function of sustained adherence to a reduced-energy diet, and most lapses in diet adherence are precipitated by temptation from palatable food. The high nonresponse and relapse rates of lifestyle interventions suggest that current temptation management approaches may be insufficient for most participants. In this conceptual review, we discuss three neurobehavioral processes (attentional bias, temporal discounting, and the cold-hot empathy gap) that emerge during temptation and contribute to lapses in diet adherence. Characterizing the neurobehavioral profile of temptation highlights an important distinction between temptation resistance strategies aimed at overcoming temptation while it is experienced, and temptation prevention strategies that seek to avoid or minimize exposure to tempting stimuli. Many temptation resistance and temptation prevention strategies heavily rely on executive functions mediated by prefrontal systems that are prone to disruption by common occurrences such as stress, insufficient sleep, and even exposure to tempting stimuli. In contrast, commitment strategies are a set of devices that enable individuals to manage temptation by constraining their future choices, without placing heavy demands on executive functions. These concepts are synthesized in a conceptual model that categorizes temptation management approaches based on their intended effects on reward processing and degree of reliance on executive functions. We conclude by discussing the implications of our model for strengthening temptation management approaches in future lifestyle interventions, tailoring these approaches based on key individual difference variables, and suggesting high-priority topics for future research.

Parents play a fundamental role in helping children with obesity to make and maintain healthy lifestyle changes. This study aimed to characterize stages of engagement to change nutrition and physical activity habits among parents whose children with obesity were enrolled in obesity management and examine differences in parents' own nutrition and physical activity habits according to their stage of engagement. Medical records of 113 children (body mass index [BMI] ≥95th percentile) enrolled in an outpatient weight management clinic were reviewed for baseline (cross-sectional) data. Parents completed the Weight Loss Behavior-Stage of Change Scale to assess the degree of engagement in making healthy changes to their lifestyle behaviours. Latent class analysis was used to classify parents into distinct clusters by grouping individuals with similar ratings of stages of engagement regarding nutrition- and physical activity-related behaviours. Parents' engagement in healthy lifestyle behaviours varied (more engaged [n = 43]; less engaged [n = 70]). A greater proportion of parents in the more engaged group was in action and/or maintenance stages of changing their lifestyle habits. The more engaged group was less overweight than the less engaged group (BMI = 28.5 vs. 33.3 kg m(-2); P < 0.05). Further, the more engaged group consumed fewer total calories, calories from fat, trans fat and carbohydrates vs. their less engaged peers (P < 0.05). Compared with the less engaged group, the more engaged group consumed more daily servings of vegetables and fruits (4.9 vs. 3.9, P < 0.05) and accumulated more steps per day (9130 vs. 7225; P < 0.05). The more engaged group was also more likely to meet daily recommendations for vegetable and fruit intake (48.8 vs. 24.3%; P < 0.05) and physical activity (42.9 vs. 22.9%, P < 0.05). Parents of children with obesity varied in their degree of engagement in making healthy changes to their lifestyle
The Whitening of Brown Fat and Its Implications for Weight Management in Obesity.
Shimizu, Ippei; Walsh, Kenneth
2015-06-01
Systemic inflammation resulting from dysfunction of white adipose tissue (WAT) accelerates the pathologies of diabetes and cardiovascular diseases. In contrast to WAT, brown adipose tissue (BAT) is abundant in mitochondria that produce heat by uncoupling respiratory chain process of ATP synthesis. Besides BAT's role in thermogenesis, accumulating evidence has shown that it is involved in regulating systemic metabolism. Studies have analyzed the "browning" processes of WAT as a means to combat obesity, whereas few studies have focused on the impact and molecular mechanisms that contribute to obesity-linked BAT dysfunction--a process that is associated with the "whitening" of this tissue. Compared to WAT, a dense vascular network is required to support the high energy consumption of BAT. Recently, vascular rarefaction was shown to be a significant causal factor in the whitening of BAT in mouse models. Vascular insufficiency leads to mitochondrial dysfunction and loss in BAT and contributes to systemic insulin resistance. These data suggest that BAT "whitening," resulting from vascular dysfunction, can impact obesity and obesity-linked diseases. Conversely, agents that promote BAT function could have utility in the treatment of these conditions.
Self discipline and obesity in Bangkok school children
2011-01-01
Background Childhood obesity has become an important public health problem in Thailand. This study aimed to determine the relationship between self discipline and obesity in Bangkok school children. Methods A case control study was conducted. 140 cases (obese children) and 140 controls (normal weight children) were randomly chosen from grades 4-6 students in 4 Bangkok public schools. Questionnaire responses regarding general characteristics and child self-discipline were obtained from children and their parents. Results Self discipline in eating habits, money management and time management were reported at significantly lower levels among the obese group (p < 0.05). After controlling all other variables, it was revealed that the ranking of factors associated with obesity by adjusted odds ratio (OR) were low self-discipline in managing expenses (3.1), poor home environment (3.0,), moderate self-discipline in time management (2.9), television viewing time ≥2 hours/day (2.6), an obese father (2.2), and an obese mother (1.9). Conclusions It was recommended that parents and teachers participate in child self-discipline guidance, particularly with regard to eating habits, money management and time management in a supportive environment that both facilitates prevention of obesity and simultaneously develops a child's personal control.

Overweight and Obesity in Children and Adolescents
Koyuncuoğlu Güngör, Neslihan
2014-01-01
Obesity among children, adolescents and adults has emerged as one of the most serious public health concerns in the 21st century. The worldwide prevalence of childhood obesity has increased remarkably over the past 3 decades. The growing prevalence of childhood obesity has also led to appearance of obesity-related comorbid disease entities at an early age. Childhood obesity can adversely affect nearly every organ system and often causes serious consequences, including hypertension, dyslipidemia, insulin resistance, dysglycemia, fatty liver disease and psychosocial complications. It is also a major contributor to increasing healthcare expenditures. For all these reasons, it is important to prevent childhood obesity as well as to identify overweight and obese children at an early stage so they can begin treatment and attain and maintain a healthy weight. At present, pharmacotherapy options for treatment of pediatric obesity are very limited. Therefore, establishing a comprehensive management program that emphasizes appropriate nutrition, exercise and behavioral modification is crucial. The physician’s role should expand beyond the clinical setting to the community to serve as a role model and to advocate for prevention and early treatment of obesity. PMID:25241606
The Immune System in Obesity: Developing Paradigms Amidst Inconvenient Truths.
Agrawal, Madhur; Kern, Philip A; Nikolajczyk, Barbara S
2017-08-15
Adipose tissue (AT) houses both innate and adaptive immune systems that are crucial for preserving AT function and metabolic homeostasis. In this review, we summarize recent information regarding progression of obesity-associated AT inflammation and insulin resistance. We additionally consider alterations in AT distribution and the immune system in males vs. females and among different racial populations. Innate and adaptive immune cell-derived inflammation drives insulin resistance both locally and systemically. However, new evidence also suggests that the immune system is equally vital for adipocyte differentiation and protection from ectopic lipid deposition. Furthermore, roles of anti-inflammatory immune cells such as regulatory T cells, "M2-like" macrophages, eosinophils, and mast cells are being explored, primarily due to promise of immunotherapeutic applications. Both immune responses and AT distribution are strongly influenced by factors like sex and race, which have been largely underappreciated in the field of metabolically-associated inflammation, or meta-flammation. More studies are required to recognize factors that switch inflammation from controlled to uncontrolled in obesity-associated pathogenesis and to integrate the combined effects of meta-flammation and immunometabolism. It is critical to recognize that the AT-associated immune system can be alternately beneficial and destructive; therefore, simply blocking immune responses early in obesity may not be the best clinical approach. The dearth of information on gender and race-associated disparities in metabolism, AT distribution, and the immune system suggest that a greater understanding of such differences will be critical to develop personalized treatments for obesity and the associated metabolic dysfunction.

Overweight and obesity in children and adolescents is often accompanied by obesity-related comorbidities. An integrative review of the literature was performed to create a comprehensive algorithm to help primary care providers manage the common comorbidities associated with childhood overweight and obesity. The Cumulative Index to Nursing and Allied Health Literature, ProQuest Nursing and Allied Health Source, and PubMed databases were searched. Evidence from 2002 to present was reviewed. Guidelines and algorithms from the American Academy of Pediatrics, National Association of Pediatric Nurse Practitioners, American Heart Association, American Diabetes Association, Centers for Disease Control and Prevention, National Heart, Lung, and Blood Institute, Agency for Healthcare and Research Quality, U.S. Department of Health and Human Services, and the International Diabetes Federation were also reviewed. Key information was extracted and data sources ranked according to the Polit and Beck evidence hierarchy. Highest level evidence guided the selection and development of recommendations to formulate a comprehensive resource for the recognition and management of pediatric hypertension, sleep apnea, vitamin D deficiency, nonalcoholic fatty liver disease, dyslipidemia, thyroid disease, diabetes mellitus, insulin resistance, metabolic syndrome, and polycystic ovarian syndrome. The Childhood Overweight and Obesity Comorbidities Resource provides a consistent, convenient point-of-care reference to help primary care providers improve pediatric health outcomes. ©2016 American Association of Nurse Practitioners.

Asian Indians exhibit unique features of obesity; excess body fat, abdominal adiposity, increased subcutaneous and intra-abdominal fat, and deposition of fat in ectopic sites (liver, muscle, etc.). Obesity is a major driver for the widely prevalent metabolic syndrome and type 2 diabetes mellitus (T2DM) in Asian Indians in India and those residing in other countries. Based on percentage body fat and morbidity data, limits of normal BMI are narrower and lower in Asian Indians than in white Caucasians. In this consensus statement, we present revised guidelines for diagnosis of obesity, abdominal obesity, the metabolic syndrome, physical activity, and drug therapy and bariatric surgery for obesity in Asian Indians after consultations with experts from various regions of India belonging to the following medical disciplines; internal medicine, metabolic diseases, endocrinology, nutrition, cardiology, exercise physiology, sports medicine and bariatric surgery, and representing reputed medical institutions, hospitals, government funded research institutions, and policy making bodies. It is estimated that by application of these guidelines, additional 10-15% of Indian population would be labeled as overweight/obese and would require appropriate management. Application of these guidelines on countrywide basis is also likely to have a deceleration effect on the escalating problem of T2DM and cardiovascular disease. These guidelines could be revised in future as appropriate, after another large and countrywide consensus process. Till that time, these should be used by clinicians, researchers and policymakers dealing with obesity and related diseases.

Obesity is a risk factor for cardiovascular disease (CVD), diabetes mellitus (DM), and hypertension (HTN). In an era of rapidly growing prevalence of obesity, it is important to explore the current knowledge, attitude, and practices of primary care physicians. Study participants were medical officers (MOs) of primary health centers in three districts of North Karnataka. The questionnaire was developed by a review of literature in the field and validated with five participants for scope, length, and clarity. Of the 102 participants, only 15% were aware about the burden of obesity in India. HTN, DM, and CVD were indicated as comorbidities by 73, 78, and 60 participants, respectively. Only 25 and 12 participants indicated appropriate body mass index (BMI) cut-off values for overweight and obesity diagnosis. Of the 102 participants, 54 were not aware of the guidelines for obesity management. Practices and attitudes of the participants were encouraging. Nearly all of them felt that the adults with BMI within the healthy range should be encouraged to maintain their weight and, three-fourth of them agreed that most overweight persons should be treated for weight loss and small weight loss can achieve major medical benefit. However, nearly half of the participants' responses were stereotypical as they felt only obese and overweight with comorbidities should be treated for weight loss. Two-thirds of them use BMI to diagnose overweight/obese and nearly all of them advice their patients to increase physical activity and restrict fat. Most of the participants were advising their patients to restrict sugar intake, increase fruits and vegetable consumption, reduce red meat, and avoid alcohol consumption. Present study exposed the lack of knowledge regarding obesity. However, practices and attitudes of the participants were promising. There is a need of in-service training to MOs to further improve their knowledge and practices towards management of obesity.

The RePPOP Aquitaine network, which was established in south-west France to prevent and treat paediatric obesity, has developed a multidisciplinary approach based on multicomponent lifestyle interventions and family-based actions. This study assessed the impact of its care management programme and investigated the factors associated with better outcomes. The impact of the RePPOP care management programme was assessed by changes in the body mass index (BMI) Z score, between baseline and the end-of-care management. We focused on 982 overweight or obese children (59.9% girls) with a mean age of 10.64 years and a range of 2.4-17.9 years. A multivariate analysis examined the independent factors associated with better outcomes. At the end-of-care management programme, 75.5% of children had decreased their BMI Z score. Initial characteristics significantly associated with better outcomes were as follows: the age at baseline between five years and 15 years of age, playing sport at a club, being followed up by RePPOP for longer than 10 months, no parental obesity and no academic difficulties. This study confirmed that multidisciplinary treatment had a significant positive effect on paediatric obesity and that social and individual factors affected the efficiency of the care management. ©2016 Foundation Acta Paediatrica.

Challenges in obesity research.
Palou, Andreu; Bonet, M Luisa
2013-09-01
Obesity is the main nutritional problem and one of the most important health problems in developed societies. Central to the challenge of obesity prevention and management is a thoroughly understanding of its determinants. Multiple socio-cultural, socio-economic, behavioural and biological factors--often interrelated and many of them still unknown or poorly understood--can contribute to the establishment and perpetuation of obese phenotypes. Here, we address current research challenges regarding basic aspects of obesity and emerging science for its control, including brown adipose tissue thermogenesis and browning of white fat as possible therapeutic targets for obesity, the influence of the microbioma, and genetics, epigenetics, nutrigenomics and nutrigenetics of obesity. We also highlight hot topics in relation to food and lifestyle as determinants of obesity, including the brain mechanisms underlying environmental motivation to eat, the biological control of spontaneous physical activity, the possible role of concrete foods and food components, and the importance of early life nutrition and environment. Challenges regarding the connections of obesity with other alterations and pathologies are also briefly addressed, as well as social and economical challenges in relation to healthy food production and lifestyle for the prevention of obesity, and technological challenges in obesity research and management. The objective is to give a panoramic of advances accomplished and still ahead relevant to the different stakeholders engaged in understanding and combating obesity.

The review assesses the role of non-pharmacologic therapy for obesity and chronic kidney disease (CKD) associated refractory hypertension (rf HTN). Hypertensive patients with markedly heightened sympathetic nervous system (SNS) activity are prone to develop refractory hypertension (rfHTN). Patients with obesity and chronic kidney disease (CKD)-associated HTN have particularly heightened SNS activity and are at high risk of rfHTN. The role of bariatric surgery is increasingly recognized in treatment of obesity. Current evidence advocates for a greater role of bariatric surgery in the management of obesity-associated HTN. In contrast, renal denervation does not appear have a role in the management of obesity or CKD-associated HTN. The role of baroreflex activation as adjunctive anti-hypertensive therapy remains to be defined.
Exercise intervention for management of obesity.

Obesity touches the lives of most Americans regardless of age. In adults, accrual of co-morbidities, including frank disability, impacts health in ways that mandate aggressive public health action. In children, the rising prevalence of overweight and obesity raises serious prospective concerns for life as these children enter adulthood. Action is imperative to provide medical interventions and preventive strategies to reduce the threat this condition poses to future generations. Obesity primarily results from an energy regulation imbalance within the body; understanding its origin and effects requires considering both the intake (via eating) and output (via moving) of energy. This article focuses on how exercise and physical activity (i.e., energy output) can influence the primary condition of obesity and its health sequelae. Components, strategies, and expected outcomes of exercise and lifestyle activity are addressed. Successful long-term participation in daily movement requires matching exercise regimens and physical activity outlets to individual preferences and environmental conditions. Activity habits of Americans must change at home and in the workplace, schools and the community to positively influence health. Although the goals of Healthy People 2010 to reduce sedentary behavior have not been met, success of other public health interventions (e.g., immunizations, use of bicycle helmets) suggests that social change to alter activity habits can be achieved. Failure to reach our public health goals should serve as a catalyst for broad-based action to help children, adolescents, and adults attain and maintain behaviors that reduce the risk of obesity and its health insults.

The growing prevalence of childhood obesity has become a serious health problem over the past decades. As the immune system is greatly affected by excess weight, in this review of reviews, we discuss the findings of review articles about the relationship between childhood/maternal obesity and children's immune system. We searched English-language articles in PubMed, Scopus, ISI Thomson Reuters, and Google Scholar databases. All relevant reviews, either systematic or narrative, were retrieved. Then their quality was assessed by using the Assessment of Multiple Systematic Reviews and International Narrative Systematic Assessment tools, respectively. In the final step, 26 reviews were included. Our review suggests that childhood obesity is associated with extensive changes in the serum levels of inflammatory and anti-inflammatory cytokines and proteins, as well as the number of immune cells and their behavior. Therefore, it might cause or exacerbate diseases such as asthma, allergy, atopic dermatitis (AD), and obstructive sleep apnea syndrome. Moreover, childhood obesity may reduce the immune system responsiveness to vaccines and microorganisms. Furthermore, studies suggest that maternal obesity increases the risk of asthma in offspring. Future studies are needed to determine different associations of childhood obesity with allergy, atophic dermatitis, and autoimmune diseases.
Systems Thinking and Simulation Modeling to Inform Childhood Obesity Policy and Practice.

In 2007, 31.7% of Georgia adolescents in grades 9-12 were overweight or obese. Understanding the impact of policies and interventions on obesity prevalence among young people can help determine statewide public health and policy strategies. This article describes a systems model, originally launched in 2008 and updated in 2014, that simulates the impact of policy interventions on the prevalence of childhood obesity in Georgia through 2034. In 2008, using information from peer-reviewed reports and quantitative estimates by experts in childhood obesity, physical activity, nutrition, and health economics and policy, a group of legislators, legislative staff members, and experts trained in systems thinking and system dynamics modeling constructed a model simulating the impact of policy interventions on the prevalence of childhood obesity in Georgia through 2034. Use of the 2008 model contributed to passage of a bill requiring annual fitness testing of schoolchildren and stricter enforcement of physical education requirements. We updated the model in 2014. With no policy change, the updated model projects that the prevalence of obesity among children and adolescents aged ≤18 in Georgia would hold at 18% from 2014 through 2034. Mandating daily school physical education (which would reduce prevalence to 12%) and integrating moderate to vigorous physical activity into elementary classrooms (which would reduce prevalence to 10%) would have the largest projected impact. Enacting all policies simultaneously would lower the prevalence of childhood obesity from 18% to 3%. Systems thinking, especially with simulation models, facilitates understanding of complex health policy problems. Using a simulation model to educate legislators, educators, and health experts about the policies that have the greatest short- and long-term impact should encourage strategic investment in low-cost, high-return policies.

Rates of overweight and obese Australians are high and continue to rise, putting a large proportion of the population at risk of chronic illness. Examining characteristics associated with preference for a work-based weight-loss program will enable employers to better target programs to increase enrolment and benefit employees' health and fitness for work. A cross-sectional survey was undertaken at two Australian mining sites. The survey collected information on employee demographics, health characteristics, work characteristics, stages of behavior change, and preference for workplace assistance with reaching a healthy weight. A total of 897 employees participated; 73.7% were male, and 68% had a body mass index in the overweight or obese range. Employees at risk of developing obesity-related chronic illnesses (based on high body mass index) were more likely to report preference for weight management assistance than lower risk employees. This indicates that, even in the absence of workplace promotion for weight management, some at risk employees want workplace assistance. Employees who were not aware of a need to change their current nutrition or physical activity behaviors were less likely to seek assistance. This indicates that practitioners need to communicate the negative effects of excess weight and promote the benefits of a healthy lifestyle to increase the likelihood of weight management. Weight management programs should provide information, motivation. and trouble-shooting assistance to meet the needs of at-risk mining employees, including those who are attempting to change and maintain behaviors to achieve a healthy weight and be suitably fit for work.

Overnutrition and sedentary lifestyle result in overweight or obesity defined as abnormal or excessive fat accumulation that may impair health. According to the WHO, the worldwide prevalence of obesity nearly doubled between 1980 and 2008. In 2008, over 50% of both men and women in the WHO European Region were overweight, and approximately 23% of women and 20% of men were obese. Comprehensive diagnostic and therapeutic approaches should include nutritional treatment to favor the best metabolic and nutritional outcome, as well as to induce potential disease-specific benefits from selected nutritional regimens. Obesity is usually accompanied by an increased muscle mass. This might explain why obesity, under particular circumstances such as cancer or high age, might have protective effects, a phenomenon named the 'obesity paradox'. However, loss of muscle mass or function can also occur, which is associated with poor prognosis and termed 'sarcopenic obesity'. Therefore, treatment recommendations may need to be individualized and adapted to co-morbidities. Since obesity is a chronic systemic disease it requires a multidisciplinary approach, both at the level of prevention and therapy including weight loss and maintenance. In the present personal review and position paper, authors from different disciplines including endocrinology, gastroenterology, nephrology, pediatrics, surgery, geriatrics, intensive care medicine, psychology and psychiatry, sports medicine and rheumatology, both at the basic science and clinical level, present their view on the topic and underline the necessity to provide a multidisciplinary approach, to address this epidemic.

This discussion reflects on concepts of obesity in children and adolescents in the early 21st century. It includes reflections on its history, definition, epidemiology, diagnostic perspectives, psychosocial considerations, musculoskeletal complications, endocrine complications and principles of management. In addition to emphasis on diet and exercise, research and clinical applications in the second decade of the 21 st century emphasize the increasing use of pharmacotherapy and bariatric surgery for adolescent and adult populations with critical problems of overweight and obesity. We conclude with a discussion of future directions in pediatric obesity management. Copyright © 2018 Mosby, Inc. All rights reserved.
Combined strategies in the management of obesity.
Dixon, John B; Dixon, Maureen E

Obesity is a chronic relapsing disease requiring a similar long term approach to management as that of other chronic conditions. Management needs to be multifaceted aiming to achieve sustainable behavioural changes to physical activity and diet to alter the patient and family microenvironment to one favouring better weight control. A range of therapies including specific diets, calorie counting, meal replacements, very low calorie diets, pharmacotherapy, intragastric balloons and surgery can provide very useful additional benefit. Use of these should be guided by the extent of weight loss required to reduce BMI to an acceptable level with regard to the patient's ethnicity, risk and comorbid conditions. Patients need to set goals that are optimistic, but realistic, and understand the benefits of sustained modest weight loss and the likelihood of weight regain requiring repeat episodes of weight loss. Practitioners need to be informed about the efficacy of current therapies and their combinations to enhance choice of suitable methods for achieving the optimal weight loss required by the patient. They will also need to anticipate trigger points for renewed periods of weight loss in the event of weight regain, as relapse is likely but not a reason for abandoning the battle.

Objective Evaluate the effects of obesity on health-related quality of life (HRQOL) measures in juvenile-onset SLE (jSLE). Methods Obesity was defined as a body mass index (BMI) ≥ 95th% according to the sex-specific Center for Disease Control body mass index-for-age charts and determined in a multicenter cohort of jSLE patients. In this secondary analysis, the domain and summary scores of the Pediatric Quality of Life (PedsQL) Inventory and the Child Health Questionnaire (CHQ) of obese jSLE patients were compared to those of non-obese jSLE patients as well as historical obese and non-obese healthy controls. Mixed-effects modeling was performed to evaluate the relationship between obesity and HRQOL measures. Results Among the 202 jSLE patients, 25% (n=51) were obese. Obesity had a significant negative impact on HRQOL in jSLE, even after adjusting for differences in current corticosteroid use, disease activity, disease damage, gender, and race between groups. Obese jSLE patients had lower physical functioning compared to non-obese jSLE patients, and to non-obese and obese healthy controls. Compared to their non-obese counterparts, obese jSLE patients also had worse school functioning, more pain, worse social functioning, and emotional functioning. Parents of obese jSLE patients worry more. The CHQ scores for obese jSLE patients were also worse compared to non-obese jSLE patients in several other domains Conclusion Our study demonstrates the detrimental effects of obesity on patient-reported outcomes in jSLE. This supports the importance of weight management for the therapeutic plan of jSLE. PMID:25335488

Data analysis based on breast cancer risk factors such as age, race, breastfeeding, hormone replacement therapy, family history, and obesity was conducted on breast cancer patients using a new enhanced computerized database management system. My Structural Query Language (MySQL) is selected as the application for database management system to store the patient data collected from hospitals in Malaysia. An automatic calculation tool is embedded in this system to assist the data analysis. The results are plotted automatically and a user-friendly graphical user interface is developed that can control the MySQL database. Case studies show breast cancer incidence rate is highest among Malay women, followed by Chinese and Indian. The peak age for breast cancer incidence is from 50 to 59 years old. Results suggest that the chance of developing breast cancer is increased in older women, and reduced with breastfeeding practice. The weight status might affect the breast cancer risk differently. Additional studies are needed to confirm these findings.

To determine the prevalence of obesity and its related comorbidities among patients being actively managed at a US academic medical centre, and to examine the frequency of a formal diagnosis of obesity, via International Classification of Diseases, Ninth Revision (ICD-9) documentation among patients with body mass index (BMI) ≥30 kg/m 2 . The electronic health record system at Cleveland Clinic was used to create a cross-sectional summary of actively managed patients meeting minimum primary care physician visit frequency requirements. Eligible patients were stratified by BMI categories, based on most recent weight and median of all recorded heights obtained on or before the index date of 1July 2015. Relationships between patient characteristics and BMI categories were tested. A large US integrated health system. A total of 324 199 active patients with a recorded BMI were identified. There were 121 287 (37.4%) patients found to be overweight (BMI ≥25 and <29.9), 75 199 (23.2%) had BMI 30-34.9, 34 152 (10.5%) had BMI 35-39.9 and 25 137 (7.8%) had BMI ≥40. There was a higher prevalence of type 2 diabetes, pre-diabetes, hypertension and cardiovascular disease (P value<0.0001) within higher BMI compared with lower BMI categories. In patients with a BMI >30 (n=134 488), only 48% (64 056) had documentation of an obesity ICD-9 code. In those patients with a BMI >40, only 75% had an obesity ICD-9 code. This cross-sectional summary from a large US integrated health system found that three out of every four patients had overweight or obesity based on BMI. Patients within higher BMI categories had a higher prevalence of comorbidities. Less than half of patients who were identified as having obesity according to BMI received a formal diagnosis via ICD-9 documentation. The disease of obesity is very prevalent yet underdiagnosed in our clinics. The under diagnosing of obesity may serve as an important barrier to treatment initiation. © Article author(s) (or
Drug treatment of obesity: current status and future prospects.
Kakkar, Ashish Kumar; Dahiya, Neha
2015-03-01
Obesity is a growing epidemic and a major contributor to the global burden of disease. Obesity strains the healthcare systems and has profound economic and psychosocial consequences. Historically, pharmacotherapy for obesity has witnessed the rise and fall of several promising drug candidates that had to be eventually withdrawn due to unacceptable safety concerns. Currently four drugs are approved for chronic weight management in obese adults: orlistat, lorcaserin, phentermine/topiramate extended release and naltrexone/bupropion extended release. While lorcaserin and phentermine/topiramate were approved by US Food and Drug Administration (FDA) in 2012, after a gap of 13 years following the licensing of orlistat, naltrexone/bupropion has been recently approved in 2014. This review provides a brief overview of these current therapeutic interventions available for management of obesity along with the evidence of their safety and efficacy. Additionally, several novel monotherapies as well as combination products are undergoing evaluation in various stages of clinical development. These therapies if proven successful will strengthen the existing armamentarium of antiobesity drugs and will be critical to combat the global public health crisis of obesity and its associated co-morbidities.

The aim of this article is to present the most relevant musculoskeletal complications known to be associated with being overweight or obese in childhood and adolescence in order to help the clinicians and physiotherapists in the diagnostic and management of these patients. Various musculoskeletal problems like slipped capital femoral epiphysis and Blount disease are well-known complications. More recent studies describe the effects of overweight on musculoskeletal pain and controversial influences on fracture rates. Reduced physical activity is a contributing factor in obesity, but also effects bone mineral accrual. Reduced postural stability and increased falls may be the reason for increased fracture rates. Furthermore these data show relevant changes of locomotion studied by gait analysis. Longitudinal kinematic studies may be needed to understand the entire aspect of gait development in overweight children. Obesity is still a serious health problem and has a relevant impact on the development of a child's musculoskeletal system. Obesity affects the locomotor sytem both functionally and structurally. Future studies are necessary to help us better understand the pathophysiology and development of optimal therapeutic strategies.
Obesity management: what brings success?

The upward trend in obesity prevalence across regions and continents is a worldwide concern. Today a majority of the world’s population live in a country where being overweight or obese causes more deaths than being underweight. Only a portion of those qualifying for treatment will get the health care they need. Still, a minor weight loss of 5–10% seems to be sufficient to provide a clinically significant health benefit in terms of risk factors for cardiovascular disease and diabetes. Diet, exercise and behavior modifications remain the current cornerstones of obesity treatment. Weight-loss drugs play a minor role. Drugs which were available and reasonably effective have been withdrawn because of side effects. The fact that the ‘old’ well known, but pretty unexciting tools remain the basic armamentarium causes understandable concern and disappointment among both patients and therapists. Hence, bariatric surgery has increasingly been recognized and developed, as it offers substantial weight loss and prolonged weight control. The present review highlights the conventional tools to counter obesity, lifestyle modification, pharmacotherapy and bariatric surgery, including some of the barriers to successful weight loss: (1) unrealistic expectations of success; (2) high attrition rates; (3) cultural norms of self-acceptance in terms of weight and beliefs of fat being healthy; (4) neighborhood attributes such as a lack of well-stocked supermarkets and rather the presence of convenience stores with low-quality foods; and (5) the perception of the neighborhood as less safe and with low walkability. Prevention is the obvious key. Cost-effective societal interventions such as a tax on unhealthy food and beverages, front-of-pack traffic light nutrition labeling and prohibition of advertising of junk food and beverages to children are also discussed.

Obesity is a highly burdensome public health issue associated with premature death, multiple comorbid disabilities and staggering healthcare costs. Between 1980-2000, the prevalence of obesity among children and adolescents nearly tripled. Obesity subjects youth to social stigmatization and discrimination. These economic and personal burdens mandate targeted prevention and detection educational programs for all individuals at risk. The most cost-effective method of approaching this obesity epidemic is through education of health professionals. As part of an "Obesity Prevention in Pediatrics" curriculum, postgraduate-year (PGY)-2 residents first observed and then participated in the dietary evaluation and counseling of pediatric patients and their families. Attitudinal questionnaires, multiple-choice knowledge examinations and a pre-established checklist of desired skills and behaviors provided evaluation of the curriculum's effect on the participants' ability and willingness to manage actually obese or at-risk pediatric patients and their families. Attitudinal survey and knowledge test scores from control PGY-3 residents generally confirmed that their knowledge and counseling skills on obesity prevention and management were well below expectation. Following participation in the curriculum, study residents' knowledge tended to improve, as did their level of comfort in counseling obese and at-risk children, adolescents and their parents. Implementation of an "Obesity Prevention in Pediatrics" curriculum appears to improve participants' knowledge base as well as their skills and level of personal comfort in the recognition, evaluation and management, including counseling, of both obese and at-risk pediatric patients and their families.
Obesity and the reproductive system disorders: epigenetics as a potential bridge.
Crujeiras, Ana B; Casanueva, Felipe F
2015-01-01
Obesity and overweight are significantly involved in several reproductive pathologies contributing to infertility in men and women. In addition, several cancers of the reproductive system, such as endometrial, ovarian, breast, testicular and prostate cancers, are strongly influenced by obesity. However, the molecular mechanisms involved in the association between obesity and reproductive disorders remain unclear. Our proposal is to review the current scientific evidence regarding the effect of obesity-related factors as the core of the collective mechanisms directly and indirectly involved in the relationship between obesity and reproductive disorders, with a special and original focus on the effect of the obesity state microenvironment on the epigenetic profile as a reversible mechanistic link between obesity and the reproductive disorders. A PubMed search was performed using keywords related to obesity and adipose-related factors and epigenetics and associated with keywords related to reproduction. Full-text articles and abstracts in the English language published prior to 31 December 2013 were reviewed. The obesity state notably contributes to a reproductive dysfunction in both men and women, ranging from infertility to oncological outcomes. Several epidemiological and experimental studies demonstrate that factors secreted by the adipose tissue and gut in an obesity state can directly induce reproductive disturbances. Relevantly, these same factors are able to alter the epigenetic regulation of genes, a dynamic and reversible mechanism by which the organism responds to environmental pressures critical to the reproductive function. This review outlines the evidence showing that the association between the reproductive pathologies and obesity is not inevitable but is potentially preventable and reversible. The epigenetic marks related to obesity could constitute a therapeutic target for the reproductive disorders associated with obesity. © The Author 2014

Obesity is a health issue of epidemic proportions in the United States, creating a health and financial burden for Medicare, Medicaid, and commercial populations alike. While obesity has been linked to an increased risk for any number of health conditions, including heart disease, diabetes, and certain cancers, even a moderate weight loss can mitigate some of the negative medical consequences of unhealthy weight. Obese individuals are often unsuccessful at meeting their weight loss goals for a variety of reasons. Many are increasingly looking to gastric bypass surgery as an easy-fix weight loss solution without fully addressing underlying issues for the original weight gain and failures with previous attempts to lose weight. Because of this, over the past five years an increase in gastric bypass surgeries has resulted in cases with poor outcomes and a subsequent reaction by health plans and employers across the country to eliminate coverage. Others have determined that, while exclusion is not the answer, neither is coverage as standard policies allow. Instead, these groups are opting to implement best practice programs that merge individualized counseling, nutritional education/ planning, and physical activity goals with specific policy changes. Evidence has shown that they are achieving success in managing obesity and its impact on healthcare costs and outcomes.

The prevalence of obesity has increased steadily in recent years. Obese people often suffer from diseases which acute decompensation requires a prompt prehospital therapy. The Emergency Medical Service will be confronted with difficulties in clinical diagnostic, therapy and especially with a delayed management of rescue and transport. It is most important to avoid prehospital depreciation in quality and time management. This article reviews the specific requirements of prehospital care of obese persons and discusses possible solutions to optimize the prehospital therapy. © Georg Thieme Verlag Stuttgart · New York.
Unique barriers and needs in weight management for obese women with fibromyalgia.

The aim of this study was to identify barriers, needs, and preferences of weight management intervention for women with fibromyalgia (FM). Obesity appears in higher rates in women with fibromyalgia compared to the population at large, and no study to date has taken a qualitative approach to better understand how these women view weight management in relation to their disease and vice versa. We designed a qualitative interview study with women patients with FM and obesity. Women (N = 15) were recruited by their participation in a fibromyalgia treatment program (FTP) within the year prior. The women approached for the study met the following inclusion criteria: confirmed diagnosis of FM, age between 30 and 60 years (M = 51 ± 6.27), and body mass index (BMI) ≥ 30 (M = 37.88 ± 4.87). Patients completed questionnaire data prior to their participation in focus groups (N = 3), including weight loss history, physical activity data, the Revised Fibromyalgia Impact Questionnaire (FIQR), and the Patient Health Questionnaire 9-item (PHQ-9). Three focus group interviews were conducted to collect qualitative data. Consistent themes were revealed within and between groups. Patients expressed the complex relationships between FM symptoms, daily responsibilities, and weight management. Weight was viewed as an emotionally laden topic requiring compassionate delivery of programming from an empathetic leader who is knowledgeable about fibromyalgia. Patients view themselves as complex and different, requiring a specifically tailored weight management program for women with FM. Women with FM identify unique barriers to weight management, including the complex interrelationships between symptoms of FM and health behaviors, such as diet and exercise. They prefer a weight management program for women with FM that consists of an in-person, group-based approach with a leader but are open to a tailored conventional weight management program. Feasibility may be one of the biggest barriers

To explore factors influencing participation and attrition in a family-led weight-management programme for obese Pacific children. Qualitative study used bilingual in-depth interviews at exit and end of an 8-week weight-management programme. New Zealand. Forty-two parents/primary caregivers of obese children who were randomised in the intervention weight-management programme. Programmatic factors that enhanced retention included: simultaneous delivery to both children and parents as participants; delivery of the programme in small group settings at local community venues; enabling trustworthy and accountable relationships; providing resources for travel to venues and regular telephone/text messaging follow-up calls reinforcing programme goals; and day and time scheduling. Suggested programme improvements included having ethnic-specific Island-language delivery and practical sessions like cooking classes and shopping expeditions at local food stores. The research found that unpredictable external life crises like extended family deaths, a change in job shift, family illnesses (both acute and those requiring chronic management) and long-term family visitations affected participation and momentum. A loss of momentum through managing life crises was often difficult to overcome for participants, leading them to drop out of the weight-management programme. Most drop-out participants preferred to defer their programme participation with hopes of re-committing to future programmes at another time. In order for weight-management programmes to be effective, participants must be able to complete them. Identifying factors that predict participation and attrition may serve as a basis for programme improvement.
Medical and surgical treatment of obesity.
Kissane, Nicole A; Pratt, Janey S A
2011-03-01
The prevalence of obesity has reached epidemic proportions. Conceptualization of obesity as a chronic disease facilitates greater understanding its treatment. The NIH Consensus Conference on Gastrointestinal Surgery for Severe Obesity provides a framework by which to manage the severely obese--specifically providing medical versus surgical recommendations which are based on scientific and outcomes data. Medical treatments of obesity include primary prevention, dietary intervention, increased physical activity, behavior modification, and pharmacotherapy. Surgical treatment for obesity is based on the extensive neural-hormonal effects of weight loss surgery on metabolism, and as such is better termed Metabolic Surgery. Surgery is not limited to the procedure itself, it also necessitates thorough preoperative evaluation, risk assessment, and counseling. The most common metabolic surgical procedures include Roux-en-Y gastric bypass, adjustable gastric band, sleeve gastrectomy, and biliopancreatic diversion. Surgical outcomes for metabolic surgery are well studied and demonstrate superior long-term weight loss compared to medical management in cases of severe obesity.

To evaluate the clinical effectiveness of weight management interventions in adults with intellectual disabilities (ID) and obesity using recommendations from current clinical guidelines for the first line management of obesity in adults. Full papers on lifestyle modification interventions published between 1982 to 2011 were sought by searching the Medline, Embase, PsycINFO and CINAHL databases. Studies were evaluated based on (1) intervention components, (2) methodology, (3) attrition rate (4) reported weight loss and (5) duration of follow up. Twenty two studies met the inclusion criteria. The interventions were classified according to inclusion of the following components: behaviour change alone, behaviour change plus physical activity, dietary advice or physical activity alone, dietary plus physical activity advice and multi-component (all three components). The majority of the studies had the same methodological limitations: no sample size justification, small heterogeneous samples, no information on randomisation methodologies. Eight studies were classified as multi-component interventions, of which one study used a 600 kilocalorie (2510 kilojoule) daily energy deficit diet. Study durations were mostly below the duration recommended in clinical guidelines and varied widely. No study included an exercise program promoting 225-300 minutes or more of moderate intensity physical activity per week but the majority of the studies used the same behaviour change techniques. Three studies reported clinically significant weight loss (≥ 5%) at six months post intervention. Current data indicate weight management interventions in those with ID differ from recommended practice and further studies to examine the effectiveness of multi-component weight management interventions for adults with ID and obesity are justified.

Obesity is a pressing public health concern, which frequently presents in primary care. With the explosive obesity epidemic, there is an urgent need to maximize effective management in primary care. The 5As of Obesity Management™ (5As) are a collection of knowledge tools developed by the Canadian Obesity Network. Low rates of obesity management visits in primary care suggest provider behaviour may be an important variable. The goal of the present study is to increase frequency and quality of obesity management in primary care using the 5As Team (5AsT) intervention to change provider behaviour. The 5AsT trial is a theoretically informed, pragmatic randomized controlled trial with mixed methods evaluation. Clinic-based multidisciplinary teams (RN/NP, mental health, dietitians) will be randomized to control or the 5AsT intervention group, to participate in biweekly learning collaborative sessions supported by internal and external practice facilitation. The learning collaborative content addresses provider-identified barriers to effective obesity management in primary care. Evidence-based shared decision making tools will be co-developed and iteratively tested by practitioners. Evaluation will be informed by the RE-AIM framework. The primary outcome measure, to which participants are blinded, is number of weight management visits/full-time equivalent (FTE) position. Patient-level outcomes will also be assessed, through a longitudinal cohort study of patients from randomized practices. Patient outcomes include clinical (e.g., body mass index [BMI], blood pressure), health-related quality of life (SF-12, EQ5D), and satisfaction with care. Qualitative data collected from providers and patients will be evaluated using thematic analysis to understand the context, implementation and effectiveness of the 5AsT program. The 5AsT trial will provide a wide range of insights into current practices, knowledge gaps and barriers that limit obesity management in primary practice

Obesity and its associated disorders are a growing epidemic across the world. Many genetic, physiological, and behavioral factors play a role in the etiology of obesity. Diet and exercise are known to play a valuable role in the treatment and prevention of obesity and associated disorders such as hypertension, heart disease, and diabetes. Therefore, the purpose of this review is to examine the prevalence, etiology, consequences, and treatment of obesity. PMID:18500955

Background: The 5As [Ask, Assess, Advise, Agree, Assist] of Obesity Management Team study was a randomized controlled trial of an intervention that was implemented and evaluated to help primary care providers improve clinical practice for obesity management. This paper presents health care provider perspectives of the impacts of the intervention on individual provider and team practices. Methods: This study reports a thematic network analysis of qualitative data collected during the 5As Team study, which involved 24 chronic disease teams affiliated with family practices in a Primary Care Network in Alberta. Qualitative data from 28 primary care providers (registered nurses/nurse practitioners [n = 14], dietitians [n = 7] and mental health workers [n = 7]) in the intervention arm were collected through semistructured interviews, field notes, practice facilitator diaries and 2 evaluation workshop questionnaires. Results: Providers internalized 5As Team intervention concepts, deepening self-evaluation and changing clinical reasoning around obesity. Providers perceived that this internalization changed the provider-patient relationship positively. The intervention changed relations between providers, increasing interdisciplinary understanding, collaboration and discovery of areas for improvement. This personal and interpersonal evolution effected change to the entire Primary Care Network. Interpretation: The 5As Team intervention had multiple impacts on providers and teams to improve obesity management in primary care. Improved provider confidence and capability is a precondition of developing effective patient interventions. Trial registration: ClinicalTrials.gov, no.: NCT01967797. PMID:28450428
The obesity epidemic: scope of the problem and management strategies.
Graves, Barbara W
2010-01-01
As the obesity epidemic increases, primary care clinicians are encountering obesity and health problems associated with obesity more frequently than ever before. In 2007, 41% of women were classified as obese, with a body mass index (BMI) of 30 or higher. Non-Hispanic blacks and Hispanics are more likely to be obese than white, non-Hispanics. A wide spectrum of health problems has been associated with obesity, including cardiovascular disease, diabetes, metabolic syndrome, osteoarthritis, and polycystic ovary syndrome. Obesity has been shown to be a low-grade inflammatory state, which may be responsible for many of the comorbidities. The general consensus recommends screening for obesity and counseling to promote weight loss. In some cases, pharmacotherapy and or bariatric surgery may be recommended.

Paradoxical Effects of Fruit on Obesity
Sharma, Satya P.; Chung, Hea J.; Kim, Hyeon J.; Hong, Seong T.
2016-01-01
Obesity is exponentially increasing regardless of its preventable characteristics. The current measures for preventing obesity have failed to address the severity and prevalence of obesity, so alternative approaches based on nutritional and diet changes are attracting attention for the treatment of obesity. Fruit contains large amounts of simple sugars (glucose, fructose, sucrose, etc.), which are well known to induce obesity. Thus, considering the amount of simple sugars found in fruit, it is reasonable to expect that their consumption should contribute to obesity rather than weight reduction. However, epidemiological research has consistently shown that most types of fruit have anti-obesity effects. Thus, due to their anti-obesity effects as well as their vitamin and mineral contents, health organizations are suggesting the consumption of fruit for weight reduction purposes. These contradictory characteristics of fruit with respect to human body weight management motivated us to study previous research to understand the contribution of different types of fruit to weight management. In this review article, we analyze and discuss the relationships between fruit and their anti-obesity effects based on numerous possible underlying mechanisms, and we conclude that each type of fruit has different effects on body weight.

The Family Nutrition and Physical Activity Screening Tool (FNPA) evaluates family behavioural and environmental factors associated with pediatric obesity, but it is unknown if FNPA scores differ among youth across obesity severities. Our aim was to determine the association between the FNPA and obesity severity in youth referred to weight management. Upon initiating treatment, height, weight, and the FNPA were collected according to standard procedures. Cut-points for overweight/obesity, severe obesity (SO) class 2, and SO class 3 were calculated. FNPA scores were compared across weight status groups using analysis of covariance, and odds of SO across FNPA quartiles were evaluated with multiple logistic regression. Participants included 564 5-18year old who initiated treatment and completed the FNPA. After adjustment, FNPA scores differed by weight status with higher/healthier scores in youth with overweight/obesity (56.6±8.5) when compared to those with SO class 2 (55.0±7.1; p=0.015) or SO class 3 (53.6±9.0; p<0.001). Compared to those in the highest FNPA quartile, youth in the 2nd quartile had 1.8 (95% CI: 1.1, 2.9) times higher odds of SO, and those in the lowest FNPA quartile had 2.1 (95% CI: 1.3, 3.4) times higher odds of SO. Youth with SO had unhealthier subscale scores among 6 of 10 constructs, including nutritional, physical activity, sedentary, and sleep behaviours. Results suggest a consistent inverse relationship between the FNPA and adiposity among youth presenting for weight management. The FNPA is a useful metric for programs and clinicians targeting family behaviours and the home environment to combat obesity. Copyright © 2016 Asia Oceania Association for the Study of Obesity.

Background Obesity levels in the UK have reached a sustained high and ∼4% of the population would be candidates for bariatric surgery based upon current UK NICE guidelines, which has important implications for Clinical Commissioning Groups. Sources of data Summary data from Cochrane systematic reviews, randomized controlled trials (RCTs) and cohort studies. Areas of agreement Currently, the only treatment that offers significant and durable weight loss for those with severe and complex obesity is surgery. Three operations account for 95% of all bariatric surgery in the UK, but the NHS offers surgery to only a small fraction of those who could benefit. Laparoscopic adjustable gastric banding (gastric banding) has potentially the lowest risk and up-front costs of the three procedures. Areas of controversy Reliable Level 1 evidence of the relative effectiveness of the operations is lacking. Growing points As a point intervention, weight loss surgery together with the chronic disease management strategy for obesity can prevent significant future disease and mortality, and the NHS should embrace both. Areas timely for developing research Better RCT evidence is needed including clinical effectiveness and economic analysis to answer the important question ‘which is the best of the three operations most frequently performed?’ This review considers the current evidence for gastric banding for the treatment of severe and complex obesity.

A multidisciplinary Tier 3 weight management service in primary care recruited patients with a body mass index ≥40 kg·m−2, or 30 kg·m−2 with obesity-related co-morbidity to a 1-year programme. A cohort of 230 participants was recruited and evaluated using the National Obesity Observatory Standard Evaluation Framework. The primary outcome was weight loss of at least 5% of baseline weight at 12 months. Diet was assessed using the two-item food frequency questionnaire, activity using the General Practice Physical Activity questionnaire and quality of life using the EuroQol-5D-5L questionnaire. A focus group explored the participants' experiences. Baseline mean weight was 124.4 kg and mean body mass index was 44.1 kg·m−2. A total of 102 participants achieved 5% weight loss at 12 months. The mean weight loss was 10.2 kg among the 117 participants who completed the 12-month programme. Baseline observation carried forward analysis gave a mean weight loss of 5.9 kg at 12 months. Fruit and vegetable intake, activity level and quality of life all improved. The dropout rate was 14.3% at 6 months and 45.1% at 1 year. Focus group participants described high levels of satisfaction. It was possible to deliver a Tier 3 weight management service for obese patients with complex co-morbidity in a primary care setting with a full multidisciplinary team, which obtained good health outcomes compared with existing services.

To provide an overview of the current advances in childhood obesity physiology, intervention, and prevention. Structural and functional brain impairments are present in obese adolescents with metabolic syndrome (MetS). Aerobic training for 20 or 40 min per day produced similar affects on metabolic risk factors. Vitamin D supplementation has been shown to improve the metabolic risk factors in obese children; however, obese children require greater doses to treat vitamin D deficiency. A 10-week community-based exergaming weight management program significantly decreased the BMI in obese children. There is surmounting research on MetS and its associated risk factors in obese children. Gaining a comprehensive overview of the factors associated with obesity in children is crucial in developing the most effective intervention strategies. Community-based and family-centered interventions have generated positive results in reducing children's BMI and improving MetS risk factors. In addition to obesity intervention efforts, ongoing prevention initiatives are imperative to reduce the prevalence of childhood obesity.
Applications of geographic information systems (GIS) data and methods in obesity-related research.

Geographic information systems (GIS) data/methods offer good promise for public health programs including obesity-related research. This study systematically examined their applications and identified gaps and limitations in current obesity-related research. A systematic search of PubMed for studies published before 20 May 2016, utilizing synonyms for GIS in combination with synonyms for obesity as search terms, identified 121 studies that met our inclusion criteria. We found primary applications of GIS data/methods in obesity-related research included (i) visualization of spatial distribution of obesity and obesity-related phenomena, and basic obesogenic environmental features, and (ii) construction of advanced obesogenic environmental indicators. We found high spatial heterogeneity in obesity prevalence/risk and obesogenic environmental factors. Also, study design and characteristics varied considerably across studies because of lack of established guidance and protocols in the field, which may also have contributed to the mixed findings about environmental impacts on obesity. Existing findings regarding built environment are more robust than those regarding food environment. Applications of GIS data/methods in obesity research are still limited, and related research faces many challenges. More and better GIS data and more friendly analysis methods are needed to expand future GIS applications in obesity-related research. © 2017 World Obesity Federation.

Obesity has been considered as a disease by the World Health Organisation since 1997. It was previously considered a simple risk factor and a manifestation of consumer society. This recognition was based on several developments, including epidemiological data showing the worldwide spread of the disease; the increasing health expenditure due to the obesity-related increase in type 2 diabetes; and progress in pathophysiological concepts. Obesity is a chronic and progressive disease. Management approaches range from prevention to surgery, and must be adapted to the individual situation.

To describe an integrated, operational platform from which mail- and telephone-based health promotion programs are implemented and to specifically relate this approach to weight management programming in a managed care setting. In-depth description of essential systems structures, including people, computer technology, and decision-support protocols. The roles of support staff, counselors, a librarian, and a manager in delivering a weight management program are described. Information availability using computer technology is a critical component in making this system effective and is presented according to its architectural layout and design. Protocols support counselors and administrative support staff in decision making, and a detailed flowchart presents the layout of this part of the system. This platform is described in the context of a weight management program, and we present baseline characteristics of 1801 participants, their behaviors, self-reported medical conditions, and initial pattern of enrollment in the various treatment options. Considering the prevalence and upward trend of overweight and obesity in the United States, a need exists for robust intervention platforms that can systematically support multiple types of programs. Weight management interventions implemented using this platform are scalable to the population level and are sustainable over time despite the limits of defined resources and budgets. The present article describes an innovative approach to reaching a large population with effective programs in an integrated, coordinated, and systematic manner. This comprehensive, robust platform represents an example of how obesity prevention and treatment research may be translated into the applied setting.
Sex hormones and systemic inflammation are modulators of the obese-asthma phenotype.

Both systemic inflammation and sex hormones have been proposed as potential mediators of the obese-asthma phenotype. The aim of this study was to examine the associations between sex hormones, oral contraceptive pill (OCP) use, systemic inflammation and airway inflammation in adults with asthma. Obese (n = 39) and nonobese (n = 42) females and obese (n = 24) and nonobese (n = 25) males with asthma were recruited. Females were further categorized as reproductive-aged (<50 years old; n = 36) or older (>50 years old; n = 45). Thirteen (36.1%) reproductive-aged females were using the OCP. Participants had induced sputum cell counts measured and blood analysed for sex hormones and inflammatory markers. Obese reproductive-aged females had higher sputum %neutrophils than nonobese reproductive-aged females (45.4 ± 24.3% vs 27.5 ± 17.5%, P = 0.016); however, there was no difference in sputum neutrophils in obese compared with nonobese males (P = 0.620) or older females (P = 0.087). Multiple linear regression analysis found testosterone and OCP use to be negative predictors of sputum %neutrophils, while C-reactive protein and IL-6 were positive predictors of sputum %neutrophils. BMI and age were not significant predictors in the multivariate model. Reproductive-aged females using the OCP had significantly lower sputum %neutrophils than those not using the OCP (23.2 ± 12.6% vs 42.1 ± 23.8%, P = 0.015). This study suggests that sex hormones and systemic inflammation may be mediating the obese-asthma phenotype. The observation that OCP use was associated with lower sputum %neutrophils in reproductive-aged females warrants further investigation. © 2016 John Wiley & Sons A/S.

Employment discrimination against obese women in obesity clinic's patients perspective.
Obara-Gołębiowska, Małgorzata
2016-01-01
The workplace is one of many areas of life where obese people are unfairly treated. According to the literature obese women are particularly susceptible to discrimination in employment. There is a lack of polish researches of this subject. The main objective of this study was to analyze personal, subjective experiences related to weight bias and discrimination against obese people in the workplace of obese Polish women. The study was carried out in a hospital clinic for obesity management. A total of 420 women with BMI>30, aged 21 to 72, participated in group interviews focused on the weight bias and discrimination against obese people in the workplace. In the group of clinically obese women, 5.3% of subjects had experienced employment discrimination and 10.5% had been victims of verbal and social abuse in the workplace. The most common psycho-physical consequences of the weight stigma were emotional problems, lack of motivation and overeating in response to stress. Weight-based discrimination in the workplace poses a problem in Poland. The weight stigma and occupational discrimination lead to psycho-physical discomfort which exacerbates overeating and obesity.
Impact of Obesity on Heart and Lung Transplantation: Does Pre-Transplant Obesity Affect Outcomes?
Bozso, S J; Nagendran, Je; Gill, R S; Freed, D H; Nagendran, Ja
2017-03-01
Increasing prevalence of obesity has led to a rise in the number of prospective obese heart and lung transplant recipients. The optimal management strategy of obese patients with end-stage heart and lung failure remains controversial. This review article discusses and provides a summary of the literature surrounding the impact of obesity on outcomes in heart and lung transplantation. Studies on transplant obesity demonstrate controversy in terms of morbidity and mortality outcomes and obesity pre-transplantation. However, the impact of obesity on outcomes seems to be more consistently demonstrated in lung rather than heart transplantation. The ultimate goal in heart and lung transplantation in the obese patient is to identify those at highest risk of complication that may warrant therapies to mitigate risk by addressing comorbid conditions.

Obesity presents a major health hazard of the 21st century. It promotes co-morbid diseases such as heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Excessive energy intake, physical inactivity, and genetic susceptibility are main causal factors for obesity, while gene mutations, endocrine disorders, medication, or psychiatric illnesses may be underlying causes in some cases. The development and maintenance of obesity may involve central pathophysiological mechanisms such as impaired brain circuit regulation and neuroendocrine hormone dysfunction. Dieting and physical exercise offer the mainstays of obesity treatment, and anti-obesity drugs may be taken in conjunction to reduce appetite or fat absorption. Bariatric surgeries may be performed in overtly obese patients to lessen stomach volume and nutrient absorption, and induce faster satiety. This review provides a summary of literature on the pathophysiological studies of obesity and discusses relevant therapeutic strategies for managing obesity. PMID:25412152

Healthy Together Victoria (HTV) - a complex 'whole of system' intervention, including an embedded cluster randomized control trial, to reduce chronic disease by addressing risk factors (physical inactivity, poor diet quality, smoking and harmful alcohol use) among children and adults in selected communities in Victoria, Australia (Healthy Together Communities). To describe the methodology for: 1) assessing changes in the prevalence of measured childhood obesity and associated risks between primary and secondary school students in HTV communities, compared with comparison communities; and 2) assessing community-level system changes that influence childhood obesity in HTC and comparison communities. Twenty-four geographically bounded areas were randomized to either prevention or comparison (2012). A repeat cross-sectional study utilising opt-out consent will collect objectively measured height, weight, waist and self-reported behavioral data among primary [Grade 4 (aged 9-10y) and Grade 6 (aged 11-12y)] and secondary [Grade 8 (aged 13-14y) and Grade 10 (aged 15-16y)] school students (2014 to 2018). Relationships between measured childhood obesity and system causes, as defined in the Foresight obesity systems map, will be assessed using a range of routine and customised data. This research methodology describes the beginnings of a state-wide childhood obesity monitoring system that can evolve to regularly inform progress on reducing obesity, and situate these changes in the context of broader community-level system change.

Obesity is an excess of fat mass. Fat mass is an energy depot but also an endocrine organ. A deregulation of the sympathetic nervous system (SNS) might produce obesity. Stress exaggerates diet-induced obesity. After stress, SNS fibers release neuropeptide Y (NPY) which directly increases visceral fat mass producing a metabolic syndrome (MbS)-like phenotype. Adrenergic receptors are the main regulators of lipolysis. In severe obesity, we demonstrated that the adrenergic receptor subtypes are differentially expressed in different fat depots. Liver and visceral fat share a common sympathetic pathway, which might explain the low-grade inflammation which simultaneously occurs in liver and fat of the obese with MbS. The neuroendocrine melanocortinergic system and gastric ghrelin are also greatly deregulated in obesity. A specific mutation in the type 4 melanocortin receptor induces early obesity onset, hyperphagia and insulin-resistance. Nonetheless, it was recently discovered that a mutation in the prohormone convertase 1/3 simultaneously produces severe gastrointestinal dysfunctions and obesity.
Lorcaserin Use in the Management of Morbid Obesity in a Pre-Liver Transplant Patient.

Management of obesity and decompensated cirrhosis in those requiring liver transplantation (LT) is a challenging dilemma. Because of concerns for perioperative complications, many centers avoid transplant in those with a body mass index (BMI) greater than 40 kg/m(2) . Bariatric surgery is associated with increased risk attributable to complications of portal hypertension, including variceal rupture. Therefore, weight loss and LT options are limited. Several new classes of weight loss drugs are commercially available, including the anoretic, lorcaserin. This case illustrates the successful use of lorcaserin in a morbidly obese individual with decompensated cirrhosis evaluated for LT listing.

Obesity is a chronic disease of increasing prevalence reaching epidemic proportions. Genetic defects as well as epigenetic effects contribute to the obesity phenotype. Investigating gene (e.g. MC4R defects)-environment (behavior, infectious agents, stress) interactions is a relative new field of great research interest. In this study, we have made an effort to create an interactome (henceforth referred to as "obesidome"), where extrinsic stressors response, intrinsic predisposition, immunity response to inflammation and autonomous nervous system implications are integrated. These pathways are presented in one interactome network for the first time. In our study, obesity-related genes/gene products were found to form a complex interactions network.

The rapid increase in childhood obesity is a serious public health problem, and has led to the development of many interventions. However, no intervention has emphasized whole grains as a strategy to manage childhood obesity. Therefore, this article describes the protocol of a 12-week multi-component, family-based intervention on whole grain, using a healthy balanced diet for managing childhood obesity. The GReat-Child trial utilize a quasi-experimental method in which two schools in Kuala Lumpur are assigned to intervention and control groups. The eligibility criteria are overweight/obese children, aged 9 through 11 years, who has no serious co-morbidities. The children who report consuming whole-grain foods in their 3-day diet-recall during the screening will be excluded. The study sample is characterized by anthropometric measurements (weight, height, percentage of body fat and waist circumference), whole grain and nutrient intakes (3-day 24-h diet recalls), and their knowledge, attitudes and practices towards whole grain. The 12-week intervention is comprised of three components addressing behaviour, personal and environmental factors, based on social cognitive theory: (1) individual diet counselling for the parents; (2) six 30-min nutrition education classes and (3) school delivery of whole-grain foods; The control school does not receive any interventions, however, for ethical purposes, a health talk is conducted after the entire GReat-Child Trial is completed. The GReat-Child trial represents a novel approach to examining the effectiveness of the intervention of whole grain in a healthy balanced diet on managing childhood obesity. We anticipate that this trial will reveal not only whether whole grain intervention will be effective in managing childhood obesity, but also provide greater insights into the acceptance of whole grain among Malaysian children.

Despite increasing prevalence of obesity, no country has successfully implemented comprehensive pathways to provide advice to all the severely obese patients that seek treatment. We aimed to formulate pathways for referral into and out of weight assessment and management clinics (WAMCs) that include internal medicine/primary care physicians as part of a multidisciplinary team that could provide specialist advice and interventions, including referral for bariatric surgery. Using a National Institute of Health and Care Excellence (NICE)-accredited process, a Guidance Development Group conducted a literature search identifying existing WAMCs. As very few examples of effective structures and clinical pathways existed, the current evidence base for optimal assessment and management of bariatric surgery patients was used to reach a consensus. The model we describe could be adopted internationally by health services to manage severely obese patients.
Neurological Consequences of Obesity
O’Brien, Phillipe D.; Hinder, Lucy M.; Callaghan, Brian C.; Feldman, Eva L.
2017-01-01
Obesity, primarily a consequence of poor dietary choices and an increased sedentary lifestyle, has become a global pandemic that brings with it enormous medical, social, and economic challenges. Not only does obesity increase the risk of cardiovascular disease and certain cancers, but it is also recognized as a key driver of other metabolic syndrome (MetS) components. These components include insulin resistance, hyperglycemia with prediabetes or type 2 diabetes, dyslipidemia, and hypertension, and are underlying contributors to systemic metabolic dysfunction. More recently, obesity and diet-induced metabolic dysfunction have been identified as risk factors for the development of a wide variety of neurological disorders in both the central and peripheral nervous systems. An abundance of literature has shown that obesity is associated with mild cognitive impairment and altered hippocampal structure and function, and there is a robust correlation between obesity and Alzheimer’s type dementia. Similarly, many reports show that both the autonomic and somatic components of the peripheral nervous system are impacted by obesity. The autonomic nervous system, under control of the hypothalamus, displays altered catabolic and anabolic processes in obese individuals attributed to sympathetic-parasympathetic imbalances. A close association also exists between obesity and polyneuropathy, a complication most commonly found in prediabetic and diabetic patients, and is likely secondary to a combination of obesity-induced dyslipidemia with hyperglycemia. This review will outline the pathophysiological development of obesity and dyslipidemia, discuss the adverse impact of these conditions on the nervous system, and provide evidence for lipotoxicity and metabolic inflammation as the drivers underlying the neurological consequences of obesity. In addition, this review will examine the benefits of lifestyle and surgical interventions in obesity-induced neurological disorders. PMID
Lowered testosterone in male obesity: mechanisms, morbidity and management
Fui, Mark Ng Tang; Dupuis, Philippe; Grossmann, Mathis
2014-01-01
With increasing modernization and urbanization of Asia, much of the future focus of the obesity epidemic will be in the Asian region. Low testosterone levels are frequently encountered in obese men who do not otherwise have a recognizable hypothalamic-pituitary-testicular (HPT) axis pathology. Moderate obesity predominantly decreases total testosterone due to insulin resistance-associated reductions in sex hormone binding globulin. More severe obesity is additionally associated with reductions in free testosterone levels due to suppression of the HPT axis. Low testosterone by itself leads to increasing adiposity, creating a self-perpetuating cycle of metabolic complications. Obesity-associated hypotestosteronemia is a functional, non-permanent state, which can be reversible, but this requires substantial weight loss. While testosterone treatment can lead to moderate reductions in fat mass, obesity by itself, in the absence of symptomatic androgen deficiency, is not an established indication for testosterone therapy. Testosterone therapy may lead to a worsening of untreated sleep apnea and compromise fertility. Whether testosterone therapy augments diet- and exercise-induced weight loss requires evaluation in adequately designed randomized controlled clinical trials. PMID:24407187

Information about the availability and effectiveness of childhood obesity training during residency is limited. We surveyed residency program directors from pediatric, internal medicine-pediatrics (IM-Peds), and family medicine residency programs between September 2007 and January 2008 about childhood obesity training offered in their programs. The response rate was 42.2% (299/709) and ranged by specialty from 40.1% to 45.4%. Overall, 52.5% of respondents felt that childhood obesity training in residency was extremely important, and the majority of programs offered training in aspects of childhood obesity management including prevention (N = 240, 80.3%), diagnosis (N = 282, 94.3%), diagnosis of complications (N = 249, 83.3%), and treatment (N = 242, 80.9%). However, only 18.1% (N = 54) of programs had a formal childhood obesity curriculum with variability across specialties. Specifically, 35.5% of IM-Peds programs had a formal curriculum compared to only 22.6% of pediatric and 13.9% of family medicine programs (p < 0.01). Didactic instruction was the most commonly used training method but was rated as only somewhat effective by 67.9% of respondents using this method. The most frequently cited significant barrier to implementing childhood obesity training was competing curricular demands (58.5%). While most residents receive training in aspects of childhood obesity management, deficits may exist in training quality with a minority of programs offering a formal childhood obesity curriculum. Given the high prevalence of childhood obesity, a greater emphasis should be placed on development and use of effective training strategies suitable for all specialties training physicians to care for children.

The prevalence of obesity has increased globally over the last 2 decades. Although the body mass index has been a convenient and simple index of obesity at the population level, studies have shown that obesity defined by body mass index alone is a remarkably heterogeneous condition with varying cardiovascular and metabolic manifestations across individuals. Adipose tissue is an exquisitely active metabolic organ engaged in cross-talk between various systems; perturbation of adipose tissue results in a pathological response to positive caloric balance in susceptible individuals that directly and indirectly contributes to cardiovascular and metabolic disease. Inadequate subcutaneous adipose tissue expansion in the face of dietary triglycerides leads to visceral and ectopic fat deposition, inflammatory/adipokine dysregulation, and insulin resistance. Conversely, preferential fat storage in the lower body depot may act as a metabolic buffer and protect other tissues from lipotoxicity caused by lipid overflow and ectopic fat. Translational, epidemiological, and clinical studies over the past 30 years have clearly demonstrated a strong link between visceral and ectopic fat and the development of a clinical syndrome characterized by atherogenic dyslipidemia, hyperinsulinemia/glucose intolerance, hypertension, atherosclerosis, and adverse cardiac remodeling/heart failure. This relationship is even more nuanced when clinical entities such as metabolically healthy obesity phenotype and the obesity paradox are considered. Although it is clear that the accumulation of visceral/ectopic fat is a major contributor to cardiovascular and metabolic risk above and beyond the body mass index, implementation of fat distribution assessment into clinical practice remains a challenge. Anthropometric indexes of obesity are easily implemented, but newer imaging-based methods offer improved sensitivity and specificity for measuring specific depots.

The purpose of the study was to evaluate a parent involvement intervention for childhood obesity intended to increase parents' skills in managing children's weight-related behavior and to improve child-parent relationships. Many studies reported on parental influence on childhood obesity, emphasizing parent involvement in prevention and management of childhood obesity. A randomized controlled trial was conducted. Forty-two parents of overweight/obese children were recruited from four cities and randomized to the experimental group or control group. The parental intervention was provided only to parents in the experimental group and consisted of weekly newsletters and text messages for a period of 5 weeks. Exercise classes and nutrition education were provided to all children. Lifestyle Behaviour Checklist and the Child-Parent Relationship Scale (CPRS) were used for measurement of parent outcome. For the child outcome, dietary self-efficacy, exercise frequency, and body mass index were measured. A mixed-design analysis of variance was performed with city location entered as a random effect. After the intervention, CPRS of parents and dietary self-efficacy of children showed an increase in the experimental group (p < .05). Intervention effects differed significantly according to the city location regarding the control efficacy of parents and dietary self-efficacy of children (p < .05). The results support the effectiveness of the parent involvement intervention in promoting child-parent relationship and dietary self-efficacy of children. However, a 5-week parent involvement intervention was not sufficient to produce significant changes in children's body mass index. Further research is needed to investigate effects of parent involvement intervention with long-term evaluation. Copyright © 2016. Published by Elsevier B.V.

Background Obesity is a pressing public health concern, which frequently presents in primary care. With the explosive obesity epidemic, there is an urgent need to maximize effective management in primary care. The 5As of Obesity Management™ (5As) are a collection of knowledge tools developed by the Canadian Obesity Network. Low rates of obesity management visits in primary care suggest provider behaviour may be an important variable. The goal of the present study is to increase frequency and quality of obesity management in primary care using the 5As Team (5AsT) intervention to change provider behaviour. Methods/design The 5AsT trial is a theoretically informed, pragmatic randomized controlled trial with mixed methods evaluation. Clinic-based multidisciplinary teams (RN/NP, mental health, dietitians) will be randomized to control or the 5AsT intervention group, to participate in biweekly learning collaborative sessions supported by internal and external practice facilitation. The learning collaborative content addresses provider-identified barriers to effective obesity management in primary care. Evidence-based shared decision making tools will be co-developed and iteratively tested by practitioners. Evaluation will be informed by the RE-AIM framework. The primary outcome measure, to which participants are blinded, is number of weight management visits/full-time equivalent (FTE) position. Patient-level outcomes will also be assessed, through a longitudinal cohort study of patients from randomized practices. Patient outcomes include clinical (e.g., body mass index [BMI], blood pressure), health-related quality of life (SF-12, EQ5D), and satisfaction with care. Qualitative data collected from providers and patients will be evaluated using thematic analysis to understand the context, implementation and effectiveness of the 5AsT program. Discussion The 5AsT trial will provide a wide range of insights into current practices, knowledge gaps and barriers that limit

To find out the differences on biomedical data between obese and non-obese participants, and to identify risk factors associated with systemic inflammation in healthy Palestinian adults. A cross-sectional study involved 105 apparently healthy adults. Interview questionnaire was used to collect personal information. Participants were excluded if they suffered from acute or chronic inflammatory diseases, or continued using medicines, which might affect the biomedical results. In association with increased Body Mass Index (BMI), the obese group displayed significant higher markers including: interleukin 6 (IL-6), high sensitivity C reactive protein (hs-CRP), total cholesterol (TC), systolic blood pressure (SBP), and diastolic blood pressure (DBP). Obese group in association with increased waist circumference (WC) was higher significantly in inflammatory markers (IL-6, hs-CRP), lipid profile (TC) and triglyceride (TG), and blood pressure (SBP, DBP). A tertile of a feature of systemic inflammation (hs-CRP) was created, by Ordinal Logistic Regression, after adjusting for the age, gender, smoking habits, physical activity pattern, father and mother's health history; risk factors were the increased BMI [OR: 1.24] (95% CI: 1.005-1.548, P=0.050), IL-6 [OR: 3.35] (95% CI: 1.341-8.398, P=0.010), DBP [OR: 1.19] (95% CI: 1.034-1.367, P=0.015), and reduced Adiponectin [OR: 0.59] (95% CI: 0.435-0.820, P=0.001). Finally, BMI correlated with IL-6 and hs-CRP (r=0.326, P=0.005; r=0.347, P<0.001; respectively), and hs-CRP correlated with IL-6 (r=0.303, P=0.010), and inversely with Adiponectin (r=-0.342, P=0.001). The increased level of IL-6 and reduced Adiponectin, which strongly associated with obesity, indicated that having high BMI is a useful marker in association with IL-6 and further developed systemic inflammation.

Strategies for the management of patients with obesity.
Hamilton, Michael
2002-01-01
The prevalence of overweight and obesity is increasing worldwide. During the last two decades, the prevalence of adults in the higher body mass index (BMI) categories in the US has increased the most, as much as 300% for those with a BMI above 40kg/m2. In children and adolescents, a doubling of the prevalence of severe overweight poses a serious health risk to future generations of young adults who may develop chronic diseases normally associated with aging. The simple definition of obesity, an imbalance between energy intake and energy expenditure, ignores the complexity of, and largely unknown interactions between, genes, food intake and physical activity, which together determine bodyweight and fat distribution. Although the etiology and manifestations of overweight and obesity are complex, the assessment of overweight and obesity requires only an accurate measurement of bodyweight, height and abdominal circumference, as well as a history and physical examination attuned to the morbidities that commonly accompany overweight and obesity such as diabetes mellitus, hypertension, dyslipidemia and sleep apnea. The treatment of patients with overweight and obesity continues to be based on changes to diet and physical activity. Simple behavior modification techniques are within the reach of busy clinicians. The additional use of available bodyweight reduction medications can reliably lead to a 5 to 10% reduction from initial bodyweight, a loss that has been shown to provide significant health benefit. The use of meal replacements has also been shown to be effective and is probably an under-appreciated treatment resource. Surgery is the most successful treatment for those with severe obesity and should be discussed as an option for those in the appropriate bodyweight categories. Because societal trends favor the greater intake of calorie-dense foods and less physical activity to accomplish the activities of daily life, the future of obesity treatment will require the

To (1) examine the opinions of medical staff working in spinal cord injury (SCI) centres (SCICs); (2) evaluate their knowledge, attitudes and practices towards obesity prevention and management; (3) report the number of beds and dietitians available at each SCIC. A 37-item questionnaire was sent to 23 SCICs in the UK, the Netherlands, Belgium and the Republic of Ireland between September 2012 and January 2013. Eighteen SCICs returned the questionnaires for analysis. All respondents stated that they had an interest in obesity treatment but only 2.3% of the respondents received training in obesity management. Sixty-one percent of staff did not consider body mass index (BMI) to be appropriate for use in SCI patients and subsequently less than half of the respondents use BMI routinely. The majority of respondents reported that they are confident in dealing with overweight (74.5%) and obese (66.1%) SCI adults, less than half (44.1%) are confident in treating overweight and obese SCI children. Respondents also indicated the need for nationally adopted guidelines and a lack of physical activity provision. There were 17.5 whole-time equivalent (WTE) dietitians recorded in 22 SCICs, equivalent to 47.8 beds per WTE dietitians (range 10-420). Non-UK SCIC dietitians are significantly better resourced than in UK SCICs (beds per WTE dietitian: 36 vs 124, P=0.035). Medical staff expressed the need to participate in obesity prevention and management. Appropriate training should be considered for all medical staff and the development of specific weight management guidelines and dietetic provision should be considered.

Background In the United States, approximately one-third of adolescents are now overweight or obese, and one in six is obese. This financial cost and the larger nonfinancial costs of obesity make obesity prevention and management for adolescents imperative for the health of the nation. However, primary care visits are typically brief, and primary care providers may lack adequate resources to help overweight or obese adolescents to manage weight issues. To augment the efficacy of primary care visits for adolescent weight management, mobile phone technology can be used as an adjunct treatment that provides additional opportunities for encouraging improvement in lifestyle, attainment, and maintenance of healthy weight. Objective The purposes of this study were to (1) measure effects of an innovative mobile phone technology-based intervention for overweight and obese adolescents and to (2) examine the intervention’s feasibility for use in primary care clinics. Methods The mobile phone-based intervention had three components: use of the Fitbit Flex, participation in an online educational program, and receipt of biweekly text messages during the maintenance phase. A randomized controlled study design was utilized. Data regarding anthropometrics (body mass index [BMI] and waist-to-hip ratio), blood pressure, levels of physical and sedentary activity, diet, and self-efficacy regarding physical activity and diet were collected at baseline and at 3 and 6 months after the baseline assessment. Results A total of 40 adolescents participated in the study. At the 6-month follow-up visit, compared to participants in the control group, the mobile phone-based intervention participants had significant improvement in BMI (z=–4.37, P=.001), diastolic blood pressure (z=–3.23, P=.001), physical activity days per week (z=2.58, P=.01), TV and computer time (z=–3.34, P=.001), servings of fruits and vegetables per day (z=2.74, P=.006), servings of soda and sweetened drinks (z=–3

Previous efforts to forecast future trends in obesity applied linear forecasts assuming that the rise in obesity would continue unabated. However, evidence suggests that obesity prevalence may be leveling off. This study presents estimates of adult obesity and severe obesity prevalence through 2030 based on nonlinear regression models. The forecasted results are then used to simulate the savings that could be achieved through modestly successful obesity prevention efforts. The study was conducted in 2009-2010 and used data from the 1990 through 2008 Behavioral Risk Factor Surveillance System (BRFSS). The analysis sample included nonpregnant adults aged ≥ 18 years. The individual-level BRFSS variables were supplemented with state-level variables from the U.S. Bureau of Labor Statistics, the American Chamber of Commerce Research Association, and the Census of Retail Trade. Future obesity and severe obesity prevalence were estimated through regression modeling by projecting trends in explanatory variables expected to influence obesity prevalence. Linear time trend forecasts suggest that by 2030, 51% of the population will be obese. The model estimates a much lower obesity prevalence of 42% and severe obesity prevalence of 11%. If obesity were to remain at 2010 levels, the combined savings in medical expenditures over the next 2 decades would be $549.5 billion. The study estimates a 33% increase in obesity prevalence and a 130% increase in severe obesity prevalence over the next 2 decades. If these forecasts prove accurate, this will further hinder efforts for healthcare cost containment. Copyright © 2012 Elsevier Inc. All rights reserved.
Type 2 diabetes and obesity in adults.
Whitmore, Catherine
There are approximately 2.5 million people in the UK with diabetes; 85-95% of whom have type 2 diabetes. Type 2 diabetes mellitus is characterized by insulin resistance and impaired insulin secretion. As approximately 90% of people with type 2 diabetes are overweight or obese, obesity is seen as a significant contributory factor in its development. This article aims to examine some of the physiological mechanisms by which overweight and obesity contribute to the development of type 2 diabetes, and review some of the approaches to managing overweight and obesity in the person with established type 2 diabetes, including dietary management, the use of reduced carbohydrate diets on glycamic control, anti-diabetes and anti-obesity drugs both in use and in development, and bariatric surgery.

Objective: To evaluate peripheral respiratory system resistance and reactance (Rrs and Xrs, respectively) in obese individuals. Methods: We recruited 99 individuals, dividing them into four groups by body mass index (BMI): < 30.0 kg/m2 (control, n = 31); 30.0-39.9 kg/m2 (obesity, n = 13); 40.0-49.9 kg/m2 (severe obesity, n = 28); and ≥ 50.0 kg/m2 (morbid obesity, n = 13). Using impulse oscillometry, we measured total Rrs, central Rrs, and Xrs. Peripheral Rrs was calculated as the difference between total Rrs and central Rrs. All subjects also underwent spirometry. Results: Of the 99 individuals recruited, 14 were excluded because they failed to perform forced expiratory maneuvers correctly during spirometry. The individuals in the severe obesity and morbid obesity groups showed higher peripheral Rrs and lower Xrs in comparison with those in the two other groups. Conclusions: Having a BMI ≥ 40 kg/m2 was associated with a significant increase in peripheral Rrs and with a decrease in Xrs. PMID:26578133

Given the prevalence of childhood obesity and the limited support for preventing and managing obesity in primary care settings, the Seattle Children's Hospital's Children's Obesity Action Team has partnered with Steps to Health King County to develop a pediatric obesity quality-improvement project. Primary care clinics joined year-long quality-improvement collaboratives to integrate obesity prevention and management into the clinic setting by using the chronic-disease model. Sustainability was enhanced through integration at multiple levels by emphasizing small, consistent behavior changes and self-regulation of eating/feeding practices with children, teenagers, and families; building local community partnerships; and encouraging broader advocacy and policy change. Cultural competency and attention to disparities were integrated into quality-improvement efforts. . Participating clinics were able to increase BMI measurement and weight classification; integrate management of overweight/obese children and family and self-management support; and grow community collaborations. Over the course of 4 years, this project grew from a local effort involving 3 clinics to a statewide program recently adopted by the Washington State Department of Health. This model can be used by other states/regions to develop pediatric obesity quality-improvement programs to support the assessment, prevention, and management of childhood obesity. Furthermore, these health care efforts can be integrated into broader community-wide childhood-obesity action plans.

Systems thinking represents an innovative and logical approach to understanding complexity in community-based obesity prevention interventions. We report on an approach to apply systems thinking to understand the complexity of a successful obesity prevention intervention in early childhood (children aged up to 5 years) conducted in a regional city in Victoria, Australia. A causal loop diagram (CLD) was developed to represent system elements related to a successful childhood obesity prevention intervention in early childhood. Key stakeholder interviews (n = 16) were examined retrospectively to generate purposive text data, create microstructures, and form a CLD. A CLD representing key stakeholder perceptions of a successful intervention comprised six key feedback loops explaining changes in project implementation over time. The loops described the dynamics of collaboration, network formation, community awareness, human resources, project clarity, and innovation. The CLD developed provides a replicable means to capture, evaluate and disseminate a description of the dynamic elements of a successful obesity prevention intervention in early childhood.
Childhood obesity in secondary care: national prospective audit of Australian pediatric practice.

In many countries, pediatricians offer skilled secondary care for children with conditions more challenging than can readily be managed in the primary care sector, but the extent to which this sector engages with the detection and management of obesity remains largely unexplored. This study aimed to audit the prevalence, diagnosis, patient, and consultation characteristics of obesity in Australian pediatric practices. This was a national prospective patient audit in Australia. During the course of 2 weeks, members of the Australian Paediatric Research Network prospectively recorded consecutive outpatient consultations by using a brief standardized data collection form. Measures included height, weight, demographics, child and parent health ratings, diagnoses, referrals, investigations, and consultation characteristics. We compared the prevalence of pediatrician-diagnosed and measured obesity (body mass index ≥95th percentile) and top-ranked diagnoses, patient, and consultation characteristics in (a) obese and nonobese children, and (b) obese children with and without a diagnosis. A total of 198 pediatricians recorded 5466 consultations with 2-17 year olds, with body mass index z-scores calculated for 3436 (62.9%). Of the 12.6% obese children, only one-third received an "overweight/obese" diagnosis. Obese children diagnosed as overweight/obese were heavier, older, and in poorer health than those not diagnosed and incurred more Medicare (government-funded health system) cost and referrals. Obesity is infrequently clinically diagnosed by Australian pediatricians and measurement practices vary widely. Further research could focus on supporting and normalizing clinical obesity activities from which pediatricians and parents could see clear benefits. Copyright © 2013 Academic Pediatric Association.

Despite the advice clinicians have been giving patients about the importance of restricting their food intake and increasing physical activity levels, the Centers for Disease Control and Prevention (CDC) states that 78.6 million adults in the United States (US) are still obese. With these statistics in mind, this symposium provided insights on the genetic, cultural, and environmental underpinning of obesity and discussed the latest research on pharmacotherapy, surgery, and the need to individualize treatment.
Prebiotics as a modulator of gut microbiota in paediatric obesity.
Nicolucci, A C; Reimer, R A
2017-08-01
This review highlights our current understanding of the role of gut microbiota in paediatric obesity and the potential role for dietary manipulation of the gut microbiota with prebiotics in managing paediatric obesity. The aetiology of obesity is multifactorial and is now known to include microbial dysbiosis in the gut. Prebiotics are non-digestible carbohydrates which selectively modulate the number and/or composition of gut microbes. The goal of prebiotic consumption is to restore symbiosis and thereby confer health benefits to the host. There is convincing evidence that prebiotics can reduce adiposity and improve metabolic health in preclinical rodent models. Furthermore, there are several clinical trials in adult humans highlighting metabolic and appetite-regulating benefits of prebiotics. In paediatric obesity, however, there are very limited data regarding the potential role of prebiotics as a dietary intervention for obesity management. As the prevalence of paediatric obesity and obesity-associated comorbidities increases globally, interventions that target the progression of obesity from an early age are essential in slowing the obesity epidemic. This review emphasizes the need for further research assessing the role of prebiotics, particularly as an intervention in effectively managing paediatric obesity. © 2016 World Obesity Federation.

Lorcaserin, plus diet and exercise, has demonstrated significant weight loss and improved cardiometabolic parameters vs. placebo in patients with overweight/obesity in three randomized, placebo-controlled trials. We examined whether lorcaserin is also associated with greater improvements in health-related quality of life (HRQOL) and whether these improvements are wholly attributable to weight loss. Pooled data from Behavioral Modification and Lorcaserin for Overweight and Obesity Management (BLOOM), Behavioral Modification and Lorcaserin Second Study for Obesity Management (BLOSSOM) and BLOOM-Diabetes Mellitus (BLOOM-DM) trials were analysed (n = 5624). HRQOL was assessed at baseline and 52 weeks using the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire. Multiple mediation analyses were conducted to evaluate the mechanisms underlying improved HRQOL. Greater HRQOL improvements were observed at 52 weeks in lorcaserin vs. placebo (P < 0.0001). A greater percentage of lorcaserin patients (54.1%) experienced meaningful improvements in IWQOL-Lite total score than placebo patients (48.2%) (P < 0.001). Body mass index (BMI) reduction was the primary driver of improved HRQOL (P < 0.0001), with depressive symptoms and total cholesterol also playing a role (P < 0.05). Improved HRQOL varied by gender, age, race and presence of diabetes and other comorbidities. Lorcaserin treatment significantly improves HRQOL compared with placebo. Although BMI reduction accounts for the majority of these improvements, improvement in depressive symptoms and total cholesterol are contributing factors. © 2017 World Obesity Federation.
Exploring the relationship between parental concern and the management of childhood obesity.
Moore, Lucas C; Harris, Carole V; Bradlyn, Andrew S
2012-05-01
Parental concern about child weight has been identified as a factor in parental monitoring and regulation of child diet. However, little is known about factors that influence parental concern or about how concern may influence parent management of child physical activity. The objectives of the current study were to identify the factors associated with parental concern about child weight and determine if parental concern is associated with specific actions to improve diet and increase physical activity. A stratified random sample of 1,500 parents of children in kindergarten, 2nd, 4th, 5th, 7th, and 9th grade were interviewed. Interviews addressed: (a) child and parent physical activity, (b) child and family nutrition, (c) child and parent BMI weight category, (d) interactions with health care providers, (e) parent obesity knowledge, (f) school assessment of BMI, and (g) parent perception of and concern about child weight. Child gender, weight status, and parent perception of child weight were significant predictors of parental concern. Parents were significantly more likely to report concern if their child was female, they believed their child to be overweight/obese, or their child was overweight/obese as indicated by BMI percentile. Concerned parents were significantly more likely to limit child screen time, take steps to improve child diet, and increase child physical activity than were parents who reported no concern. Treatment and prevention efforts should emphasize parental concern and awareness about child weight by providing accurate feedback on child weight status and education regarding the health risks associated with childhood overweight and obesity. Schools can play an important role in this process through the incorporation of BMI screenings.

Background Information about the availability and effectiveness of childhood obesity training during residency is limited. Methods We surveyed residency program directors from pediatric, internal medicine-pediatrics (IM-Peds), and family medicine residency programs between September 2007 and January 2008 about childhood obesity training offered in their programs. Results The response rate was 42.2% (299/709) and ranged by specialty from 40.1% to 45.4%. Overall, 52.5% of respondents felt that childhood obesity training in residency was extremely important, and the majority of programs offered training in aspects of childhood obesity management including prevention (N = 240, 80.3%), diagnosis (N = 282, 94.3%), diagnosis of complications (N = 249, 83.3%), and treatment (N = 242, 80.9%). However, only 18.1% (N = 54) of programs had a formal childhood obesity curriculum with variability across specialties. Specifically, 35.5% of IM-Peds programs had a formal curriculum compared to only 22.6% of pediatric and 13.9% of family medicine programs (p < 0.01). Didactic instruction was the most commonly used training method but was rated as only somewhat effective by 67.9% of respondents using this method. The most frequently cited significant barrier to implementing childhood obesity training was competing curricular demands (58.5%). Conclusions While most residents receive training in aspects of childhood obesity management, deficits may exist in training quality with a minority of programs offering a formal childhood obesity curriculum. Given the high prevalence of childhood obesity, a greater emphasis should be placed on development and use of effective training strategies suitable for all specialties training physicians to care for children.

Metabolic signals and innate immune activation in obesity and exercise.
Ringseis, Robert; Eder, Klaus; Mooren, Frank C; Krüger, Karsten
2015-01-01
The combination of a sedentary lifestyle and excess energy intake has led to an increased prevalence of obesity which constitutes a major risk factor for several co-morbidities including type 2 diabetes and cardiovascular diseases. Intensive research during the last two decades has revealed that a characteristic feature of obesity linking it to insulin resistance is the presence of chronic low-grade inflammation being indicative of activation of the innate immune system. Recent evidence suggests that activation of the innate immune system in the course of obesity is mediated by metabolic signals, such as free fatty acids (FFAs), being elevated in many obese subjects, through activation of pattern recognition receptors thereby leading to stimulation of critical inflammatory signaling cascades, like IκBα kinase/nuclear factor-κB (IKK/NF- κB), endoplasmic reticulum (ER) stress-induced unfolded protein response (UPR) and NOD-like receptor P3 (NLRP3) inflammasome pathway, that interfere with insulin signaling. Exercise is one of the main prescribed interventions in obesity management improving insulin sensitivity and reducing obesity- induced chronic inflammation. This review summarizes current knowledge of the cellular recognition mechanisms for FFAs, the inflammatory signaling pathways triggered by excess FFAs in obesity and the counteractive effects of both acute and chronic exercise on obesity-induced activation of inflammatory signaling pathways. A deeper understanding of the effects of exercise on inflammatory signaling pathways in obesity is useful to optimize preventive and therapeutic strategies to combat the increasing incidence of obesity and its comorbidities.

Epigenetics and obesity cardiomyopathy: From pathophysiology to prevention and management.
Zhang, Yingmei; Ren, Jun
2016-05-01
Uncorrected obesity has been associated with cardiac hypertrophy and contractile dysfunction. Several mechanisms for this cardiomyopathy have been identified, including oxidative stress, autophagy, adrenergic and renin-angiotensin aldosterone overflow. Another process that may regulate effects of obesity is epigenetics, which refers to the heritable alterations in gene expression or cellular phenotype that are not encoded on the DNA sequence. Advances in epigenome profiling have greatly improved the understanding of the epigenome in obesity, where environmental exposures during early life result in an increased health risk later on in life. Several mechanisms, including histone modification, DNA methylation and non-coding RNAs, have been reported in obesity and can cause transcriptional suppression or activation, depending on the location within the gene, contributing to obesity-induced complications. Through epigenetic modifications, the fetus may be prone to detrimental insults, leading to cardiac sequelae later in life. Important links between epigenetics and obesity include nutrition, exercise, adiposity, inflammation, insulin sensitivity and hepatic steatosis. Genome-wide studies have identified altered DNA methylation patterns in pancreatic islets, skeletal muscle and adipose tissues from obese subjects compared with non-obese controls. In addition, aging and intrauterine environment are associated with differential DNA methylation. Given the intense research on the molecular mechanisms of the etiology of obesity and its complications, this review will provide insights into the current understanding of epigenetics and pharmacological and non-pharmacological (such as exercise) interventions targeting epigenetics as they relate to treatment of obesity and its complications. Particular focus will be on DNA methylation, histone modification and non-coding RNAs. Copyright © 2016 Elsevier Inc. All rights reserved.
Current attitudes and practices of obesity counselling by health care providers.
Petrin, Christine; Kahan, Scott; Turner, Monique; Gallagher, Christine; Dietz, William H
Relatively few patients receive obesity counselling consistent with the USPSTF guidelines, and many health care professionals (HCPs) are biased in their attitudes towards obesity management. A national sample of family physicians, internists, OB/GYN physicians, and nurse practitioners (NPs) completed a web-based survey of beliefs, practice, and knowledge regarding obesity management. A majority of HCPs believe that it is both the patient's and the provider's responsibility to ensure that the patient is counselled about obesity. Obesity (77%), obesity-related diseases (79%), or obesity-related risk factors (71%) prompt HCPs to offer obesity counselling; 59% of HCPs wait for the patient to broach the subject of their weight. Increased blood pressure (89%) and heart disease risks (90%) are the most common themes in counselling. Across all HCPs except NPs "exercise" is discussed more frequently than "physical activity" (85% vs 81%), "diet" more frequently than "eating habits" (77% vs 75%), and "obesity" more frequently than "unhealthy weight" (60% vs 45%). NPs are more likely to discuss physical activity, eating habits, and unhealthy weight instead. To improve counselling for obesity, HCPs reported needing more time (70%), training in obesity management (53%), improved reimbursement (53%), and better tools to help patients recognise obesity risks (50%). Obesity-related diseases, risk factors, or obesity alone predict obesity counselling amongst HCPs. Better training in weight management and tools to help patients recognise risks appear to be key elements in helping patients compare the risks of what they may consider invasive therapy against the risks of continued obesity.

The sensitivity of the appetite system of a group of obese individuals was assessed in response to two challenges known to reduce hunger and enhance satiety in lean people. The challenges were the presentation of a caloric (high protein) load and the activation of serotonin systems. Eight obese female adults (BMI = 38) received 2 X 15 mg d-fenfluramine or placebo daily for 3 days, the study conforming to a 2 X 2 factor (drug X lunch type), double blind, repeated measures design. Three hours after dosing on day 3 they ate either a high carbohydrate (63 percent of total energy) or high protein (54 percent) lunchtime meal (the caloric load). These fixed meal challenges were equal in energy (475 kcal), weight and fat content. Ratings of hunger motivation and food preferences were tracked over the course of lunch and for a further 3 hours, at which point subjects returned for a self-selection test meal. Intakes from this second open meal revealed significant main effects of both caloric load and drug on energy intake, with the high protein d-fenfluramine combination being the most potent anorectic pairing. These findings were supported by the profiles of hunger motivation. This study has confirmed that the appetite system of these subjects was responsive to these biologically relevant challenges. The results suggest that the combination of an appetite modulating drug with specific dietary intervention may represent an effective strategy for the management of hunger arising from caloric restriction.

We demonstrate the use of a systems-based framework to assess solutions to complex health problems such as obesity. We coded 12 documents published between 2004 and 2013 aimed at influencing obesity planning for complex systems design (9 reports from US and Canadian governmental or health authorities, 1 Cochrane review, and 2 Institute of Medicine reports). We sorted data using the intervention-level framework (ILF), a novel solutions-oriented approach to complex problems. An in-depth comparison of 3 documents provides further insight into complexity and systems design in obesity policy. The majority of strategies focused mainly on changing the determinants of energy imbalance (food intake and physical activity). ILF analysis brings to the surface actions aimed at higher levels of system function and points to a need for more innovative policy design. Although many policymakers acknowledge obesity as a complex problem, many strategies stem from the paradigm of individual choice and are limited in scope. The ILF provides a template to encourage natural systems thinking and more strategic policy design grounded in complexity science.

The escalating epidemic of obesity has increased the incidence of obesity-induced complications to historically high levels. Adipose tissue is a dynamic energy depot, which stores energy and mobilizes it during nutrient deficiency. Excess nutrient intake resulting in adipose tissue expansion triggers lipid release and aberrant adipokine, cytokine and chemokine production, and signaling that ultimately lead to adipose tissue inflammation, a hallmark of obesity. This low-grade chronic inflammation is thought to link obesity to insulin resistance and the associated comorbidities of metabolic syndrome such as dyslipidemia and hypertension, which increase risk of type 2 diabetes and cardiovascular disease. In this review, we focus on and discuss members of the chemokine system for which there is clear evidence of participation in the development of obesity and obesity-induced pathologies. PMID:24741577

Parental obesity is a risk factor for offspring obesity. It is unclear whether parental obesity also confers risk for obesity-associated conditions (e.g., a proinflammatory or prothrombotic state) in the absence of offspring obesity. We compared concentrations of multiple biomarkers representing distinct biological pathways (C-reactive protein [CRP], aldosterone, renin, B-type natriuretic peptide, NH(2)-terminal proatrial natriuretic peptide, fibrinogen, and plasminogen activator inhibitor-1) in nonobese Framingham Offspring Study participants with no parents (n = 665), one parent (n = 488), or two parents (n = 119) with obesity (BMI > or =30 kg/m(2)). Nonobese offspring with both parents with obesity had higher CRP levels (median 2.16 mg/l) than offspring with one parent (1.58 mg/l) or no parents (1.35 mg/l) with obesity. After multivariable adjustment, a nonlinear relationship with parental obesity became evident: compared with those without parental obesity, CRP levels were higher in offspring with two obese parents (P = 0.04) but not in offspring with only one obese parent (P = 0.76). Renin levels were more linearly related to parental obesity status, being significantly higher in offspring with one parent (P = 0.04) or two parents (P = 0.09) with obesity (P = 0.02 for trend). The other systemic biomarkers did not vary according to parental obesity status (all P > 0.05). Our findings suggest that offspring with a high risk of developing obesity have an altered biomarker profile, characterized by systemic inflammation and increased neurohormonal activity, even in the absence of obesity. This is consistent with the notion that parental obesity may confer an increased susceptibility to other adiposity-associated traits.

This study was done to determine the effects of weight management program using self-efficacy in middle-aged obese women. The study also attempted to measure the effects of the program on the weight efficacy lifestyle, body composition, and depression. The research design of this study was a nonequivalent control group pretest-posttest design. The experimental group consisted of 21 middle-aged obese women and another 21 middle-aged obese women in the control group. The women in the experimental group participated in the weight management program for 12 weeks using self-efficacy. The weight management program using self-efficacy included education on effects of exercise for weight control, aerobic exercise program, muscle training and counseling through the telephone. After 12 weeks of participation in the program, BMI (p<.0001), body fat % (p<.0001), abdominal fat (p<.0001), in the experimental group were significantly decreased compared to the control group. Weight self-efficacy lifestyle (p<.0001) and depression (p=.006) in the experimental group were significantly improved after the program compared to the control group. According to these findings, weight management program self-efficacy for middle-aged obese women could increase weight efficacy lifestyle, and decrease depression, BMI, body fat, and abdominal fat. The result also suggested that the increasing weight efficacy and lifestyle help the obese women to perform and continue exercise. This program could be used in the community such as public health center for weight care and mental health promotion of middle-aged obese women.

Overweight and obesity prevalence has increased over the past 30 years. Few studies have looked at the enrolled Military Health System (MHS) population (2.2 million per year). This descriptive study examined trends in overweight and obesity in both children and adults from fiscal years 2009 to 2012 and compared them to the U.S. population. Prevalence in MHS children decreased over time for overweight (14.2-13.8%) and obesity (11.7-10.9%). Active duty adults showed an increase in overweight prevalence (52.7-53.4%) and a decrease in obesity prevalence (18.9-18.3%). For nonactive duty, both overweight and obesity prevalence remained relatively unchanged around 33%. For both children and adults, overweight and obesity prevalence increased with age, except for obesity in the nonactive duty ≥ 65 subgroup. When compared to the United States by gender and age, MHS children generally had a lower overweight and obesity prevalence, active duty adults had higher overweight and lower obesity prevalence, and nonactive duty adults had comparable overweight and obesity prevalence, except for obesity in both men in the 40 to 59 subgroup and women in ≥ 60 subgroup. More research on the MHS population is needed to identify risk factors and modifiable health behaviors that could defeat the disease of obesity.

Obese individuals are more likely to develop heart failure. Yet, once heart failure is established, the impact of overweight and obesity on prognosis and survival is unclear. The purpose of this joint scientific statement of the European Association for the Study of Obesity and the European Society of Hypertension is to provide an overview on the current scientific literature on obesity and heart failure in terms of prognosis, mechanisms, and clinical management implications. Moreover, the document identifies open questions that ought to be addressed. The need for more tailored weight management recommendations in heart failure will be emphasized and, in line with the emerging evidence, aims to distinguish between primary disease and secondary outcome prevention. In the primary prevention of heart failure, it appears prudent advising obese individuals to lose or achieve a healthy body weight, especially in those with risk factors such as hypertension or type 2 diabetes. However, there is no evidence from clinical trials to guide weight management in overweight or obese patients with established heart failure. Prospective clinical trials are strongly encouraged.

Obesity is a chronic disease, and it requires chronic therapy. Hypertension, dyslipidemia, diabetes and cardiovascular diseases are leading causes of mortality in the modern world. All of them are strongly linked to obesity. While treating obesity, those conditions are also managed. Obese patients should always be treated through lifestyle interventions, though the results of such interventions are modest. Pharmacotherapy is a second step in the treatment of obesity, approved only when weight loss targets were not reached through lifestyle intervention. During the history of antiobesity drugs, many of them were withdrawn because of their side effects. Various guidelines recommend prescribing drug therapy for obesity through consideration of the potential benefits and limitations. Orlistat deactivates intestinal lipase and inhibits intestinal fat lipolysis. It is actually the only drug on the European market approved for the treatment of obesity. Orlistat therapy reduces weight to a modest extent, but it reduces the incidence of diabetes beyond the result achieved with lifestyle changes. Recently, some effective antiobesity drugs like sibutramine and rimonabant have been removed from the market due to their side effects. The new combination of topimarate and fentermine is approved in the US but not in Europe. The cost effectiveness of long-term pharmacotherapy of obesity is still an unresolved question.

Obesity affects more than 35% of Americans, increasing the risk of more than 200 comorbid conditions, impaired quality of life and premature mortality. This review aimed to summarize literature published over the past 15 years regarding the prevalence and impact of obesity in people with haemophilia (PWH) and to discuss implementing general guidelines for weight management in the context of the haemophilia comprehensive care team. Although few studies have assessed the effects of obesity on haemophilia-specific outcomes, existing evidence indicates an important impact of weight status on lower extremity joint range of motion and functional disability, with potentially important effects on overall quality of life. Data regarding bleeding tendency in PWH with coexisting obesity are largely inconclusive; however, some individuals may experience reduced joint bleeds following moderate weight loss. Additionally, conventional weight-based dosing of factor replacement therapy leads to increased treatment costs for PWH with obesity or overweight, suggesting pharmacoeconomic benefits of weight loss. Evidence-based recommendations for weight loss include behavioural strategies to reduce caloric intake and increase physical activity, pharmacotherapy and surgical therapy in appropriate patients. Unique considerations in PWH include bleed-related risks with physical activity; thus, healthcare professionals should advise patients on types and intensities of, and approaches to, physical activity, how to adjust treatment to accommodate exercise and how to manage potential activity-related bleeding. Increasing awareness of these issues may improve identification of PWH with coexisting obesity and referral to appropriate specialists, with potentially wide-ranging benefits in overall health and well-being. © 2017 The Authors.

The Chronic Care Model (CCM) is helpful to illustrate multiple levels of influence in the management of chronic disease, such as overweight and obesity in adolescents. Unfortunately, various constraints create gaps in the management process activities performed within the CCM. Consumer health technologies (CHT) may serve as a linkage between adolescents with overweight or obesity, their parents, and their pediatricians. To conduct formative research to qualitatively identify views of adolescents with overweight and obesity on use of consumer health technologies to manage weight loss across chronic care management settings. As part of a multi-perspective qualitative study, 10 focus groups were conducted with adolescents with overweight and obesity. Forty-eight adolescents (15 male, 33 female) aged 12 to 17 years who were current participants of an intensive lifestyle change camp in the summer of 2012 participated in focus groups. All adolescents were classified as overweight (21%) or obese (79%) according to body mass index (BMI) for age charts published by the Centers for Disease Control and Prevention. All focus groups were recorded, transcribed verbatim, and checked for accuracy. Predefined and open coding were used to analyze transcripts for emerging themes. Adolescents perceive CHT, with its functional requirements of assistance with restaurant food selection, teaching cooking skills, and providing encouragement and motivation, to be helpful with overweight and obesity self-management. Desired features to carry out these functional requirements included avatars, self-monitoring capabilities, social networking, and rewards. Our findings largely agree with previously reported parental perceptions of the benefit of CHT for adolescent overweight and obesity self-management and strengthen support for the design and implementation of CHT within the CCM.

Environmental Perturbations: Obesity
Shore, Stephanie A.
2014-01-01
Obesity currently affects about one third of the U.S. population, while another one third is overweight. The importance of obesity for certain conditions such as heart disease and type 2 diabetes is well appreciated. The effects of obesity on the respiratory system have received less attention and are the subject of this chapter. Obesity alters the static mechanic properties of the respiratory system leading to a reduction in the functional residual capacity (FRC) and the expiratory reserve volume (ERV). There is substantial variability in the effects of obesity on FRC and ERV, at least some of which is related to the location, rather than the total mass of adipose tissue. Obesity also results in airflow obstruction, which is only partially attributable to breathing at low lung volume, and can also promote airway hyperresponsiveness and asthma. Hypoxemia is common is obesity, and correlates well with FRC, as well as with measures of abdominal obesity. However, obese subjects are usually eucapnic, indicating that hypoventilation is not a common cause of their hypoxemia. Instead, hypoxemia results from ventilation perfusion mismatch caused by closure of dependent airways at FRC. Many obese subjects complain of dyspnea either at rest or during exertion, and the dyspnea score also correlates with reductions in FRC and ERV. Weight reduction should be encouraged in any symptomatic obese individual, since virtually all of the respiratory complications of obesity improve with even moderate weight loss. PMID:23737172

This study used focus group methodology to examine perceptions of obesity and weight management among Latina immigrant women in Alabama. Four focus groups (N = 25) were conducted in Spanish as part of a participatory intervention development process. Participants were obese/overweight Latina immigrant women (BMI > 25) primarily recruited from a community hospital. The majority of participants were from Mexico. Participants described obesity in the context of short-term effects such as physical symptoms and aesthetics. Perceived weight gain was related to lifestyle changes since moving to the US. Social isolation, depression, and stress were reported to contribute to weight gain. Participants expressed interest in weight loss but emphasized a desire for programs that preserve traditional foods and include family. Weight-management programs designed for Latina immigrants should address their perceptions of obesity. This data also suggests that those interventions that preserve culture and incorporate family may have increased community buy-in.
A sympathetic nervous system evaluation of obesity stigma.
Oliver, Michael D; Datta, Subimal; Baldwin, Debora R

The portrayal of obesity in the media is often one of negativity. Consequently, it may generate an increase in stigma. Obesity stigma, a form of social discrimination, is responsible for many of the negative psychological and physiological effects on individual wellness. These effects not only impact individual health, but also affect the economy, and ultimately, societal wellness. In an attempt to examine the influence of the media on obesity stigma, this study tested the hypothesis that positive priming would lead to a reduction in obesity stigma. To further our understanding of this relationship, we: 1) examined the role of priming on physiological measures (e.g. salivary alpha amylase and skin conductance) in 70 college students by introducing positive and negative media images of individuals with obesity, and 2) assessed psychological measures (e.g. perceived stress, need to belong, and self-esteem, and Body Mass Index). After the priming manipulation, participants read a vignette depicting the discrimination of an individual with obesity and answered subsequent questions assessing participants' attributional blame of obesity. Results of this study revealed that priming affects physiological responding to obesity stigmatization. In conclusion, these findings suggest that incorporating positive media images of individuals with obesity may be an effective tool for reducing stigma and the various physiological consequences associated with it, which in turn, can enhance societal health and wellness.

The results of psychological tests of the obese are inconsistent and no characteristic personality structure of the obese can be deduced from them. Investigations in childhood obesity failed to establish a general psychogenetic model of obesity. Yet overweight and ideal weight-subjects differ in spontaneous eating behaviour. Appetite and satiety of obese subjects are controlled by external stimuli to a far greater extent than in nonobese. From a behavioural scientific viewpoint it is proposed that learning experiences during childhood socialisation generate the disposition for obesity which can manifest itself later, after interaction with a special environment. At this stage, however, individual reactions to starting overweight are insolved; this process is strongly influenced by individual personality structures: an inadequate conflict management favours obesity; by cognitive control normal weight can be preserved in spite of the acquired disposition for obesity. Taking these "latently obese" as an example the role of personality structure and wrong eating habits is discussed and related to possible therapeutic strategies. A model of the psychogenetic basis of obesity is proposed. In this model eating-related learning experience is attributed a primary role and individual personality structure a secondary role in the psychogenesis of obesity.
Gastrointestinal Complications of Obesity

Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett’s esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

Thinking Evolutionarily About Obesity
Genné-Bacon, Elizabeth A.
2014-01-01
Obesity, diabetes, and metabolic syndrome are growing worldwide health concerns, yet their causes are not fully understood. Research into the etiology of the obesity epidemic is highly influenced by our understanding of the evolutionary roots of metabolic control. For half a century, the thrifty gene hypothesis, which argues that obesity is an evolutionary adaptation for surviving periods of famine, has dominated the thinking on this topic. Obesity researchers are often not aware that there is, in fact, limited evidence to support the thrifty gene hypothesis and that alternative hypotheses have been suggested. This review presents evidence for and against the thrifty gene hypothesis and introduces readers to additional hypotheses for the evolutionary origins of the obesity epidemic. Because these alternate hypotheses imply significantly different strategies for research and clinical management of obesity, their consideration is critical to halting the spread of this epidemic.

In the United States, approximately one-third of adolescents are now overweight or obese, and one in six is obese. This financial cost and the larger nonfinancial costs of obesity make obesity prevention and management for adolescents imperative for the health of the nation. However, primary care visits are typically brief, and primary care providers may lack adequate resources to help overweight or obese adolescents to manage weight issues. To augment the efficacy of primary care visits for adolescent weight management, mobile phone technology can be used as an adjunct treatment that provides additional opportunities for encouraging improvement in lifestyle, attainment, and maintenance of healthy weight. The purposes of this study were to (1) measure effects of an innovative mobile phone technology-based intervention for overweight and obese adolescents and to (2) examine the intervention's feasibility for use in primary care clinics. The mobile phone-based intervention had three components: use of the Fitbit Flex, participation in an online educational program, and receipt of biweekly text messages during the maintenance phase. A randomized controlled study design was utilized. Data regarding anthropometrics (body mass index [BMI] and waist-to-hip ratio), blood pressure, levels of physical and sedentary activity, diet, and self-efficacy regarding physical activity and diet were collected at baseline and at 3 and 6 months after the baseline assessment. A total of 40 adolescents participated in the study. At the 6-month follow-up visit, compared to participants in the control group, the mobile phone-based intervention participants had significant improvement in BMI (z=-4.37, P=.001), diastolic blood pressure (z=-3.23, P=.001), physical activity days per week (z=2.58, P=.01), TV and computer time (z=-3.34, P=.001), servings of fruits and vegetables per day (z=2.74, P=.006), servings of soda and sweetened drinks (z=-3.19, P=.001), physical activity self-efficacy (z=2

The brain's reward system is crucial to understand obesity in modern society, as increased neural responsivity to reward can fuel the unhealthy food choices that are driving the growing obesity epidemic. Brain's reward system responsivity to food and monetary rewards in individuals with excessive weight (overweight and obese) versus normal weight controls, along with the relationship between this responsivity and body mass index (BMI) were tested. The sample comprised 21 adults with obesity (BMI > 30), 21 with overweight (BMI between 25 and 30), and 39 with normal weight (BMI < 25). Participants underwent a functional magnetic resonance imaging (fMRI) session while performing two tasks that involve the processing of food (Willing to Pay) and monetary rewards (Monetary Incentive Delay). Neural activations within the brain reward system were compared across the three groups. Curve fit analyses were conducted to establish the association between BMI and brain reward system's response. Individuals with obesity had greater food-evoked responsivity in the dorsal and ventral striatum compared with overweight and normal weight groups. There was an inverted U-shape association between BMI and monetary-evoked responsivity in the ventral striatum, medial frontal cortex, and amygdala; that is, individuals with BMIs between 27 and 32 had greater responsivity to monetary stimuli. Obesity is associated with greater food-evoked responsivity in the ventral and dorsal striatum, and overweight is associated with greater monetary-evoked responsivity in the ventral striatum, the amygdala, and the medial frontal cortex. Findings suggest differential reactivity of the brain's reward system to food versus monetary rewards in obesity and overweight.

As childhood obesity is a concern in many communities, this study investigated outpatient evaluation and initial management of overweight and obese pediatric patients in U.S. military medical treatment facilities (MTFs). Samples of 579 overweight and 341 obese patients (as determined by body mass index [BMI]) aged 3-17 years were drawn from MTFs. All available FY2011 outpatient records were searched for documentation of BMI assessment, overweight/obesity diagnosis, and counseling. Administrative data for these patients were merged to assess coded diagnostic and counseling rates and receipt of recommended laboratory screenings. Generic BMI documentation was high, but BMI percentile assessments were found among fewer than half the patients. Diagnostic recording or recognition totaled 10.9% of overweight and 32.0% of obese. Counseling rates were higher, with 46.4% and 61.0% of overweight and obese patients, respectively, receiving weight related counseling. Among patients 10 years of age or older, rates of recommended lab screenings for diabetes, liver abnormality, and dyslipidemia were not greater than 33%. BMI percentile recording was strongly associated with diagnostic recording, and diagnostic recording was strongly associated with counseling. Improvements to electronic health records or implementation of local procedures to facilitate better diagnostic recording would likely improve adherence to clinical practice guidelines. ©2016 American Association of Nurse Practitioners.
Obesity Prevalence by Occupation in Washington State, Behavioral Risk Factor Surveillance System
Lu, Dayu; Fan, Z. Joyce
2014-01-01
Introduction Data that estimate the prevalence of and risk factors for worker obesity by occupation are generally unavailable and could inform the prioritization of workplace wellness programs. The aims of this study were to estimate the prevalence of obesity by occupation, examine the association of occupational physical activity and a range of health behaviors with obesity, and identify occupations in which workers are at high risk of obesity in Washington State. Methods We conducted descriptive and multivariable analyses among 37,626 employed Washington State respondents using the Behavioral Risk Factor Surveillance System in odd numbered years, from 2003 through 2009. We estimated prevalence and prevalence ratios (PRs) by occupational groups adjusting for demographics, occupational physical activity level, smoking, fruit and vegetable consumption, and leisure-time physical activity (LPTA). Results Overall obesity prevalence was 24.6% (95% confidence interval [CI], 24.0–25.1). Workers in protective services were 2.46 (95% CI, 1.72–3.50) times as likely to be obese as workers in health diagnosing occupations. Compared with their counterparts, workers who consumed adequate amounts of fruits and vegetables and had adequate LTPA were significantly less likely to be obese (PR = 0.91; 95% CI, 0.86–0.97 and PR = 0.63; 95% CI, 0.60–0.67, respectively). Workers with physically demanding occupational physical activity had a lower PR of obesity (PR = 0.83; 95% CI, 0.78–0.88) than those with nonphysically demanding occupational physical activity. Conclusion Obesity prevalence and health risk behaviors vary substantially by occupation. Employers, policy makers, and health promotion practitioners can use our results to target and prioritize workplace obesity prevention and health behavior promotion programs. PMID:24406093

Obesity has been linked to several types of cancer. Access to adequate health information activates people's participation in managing their own health, which ultimately improves their health outcomes. Nevertheless, the existing online information about the relationship between obesity and cancer is heterogeneous and poorly organized. A formal knowledge representation can help better organize and deliver quality health information. Currently, there are several efforts in the biomedical domain to convert unstructured data to structured data and store them in Semantic Web knowledge bases (KB). In this demo paper, we present, OC-2-KB (Obesity and Cancer to Knowledge Base), a system that is tailored to guide the automatic KB construction for managing obesity and cancer knowledge from free-text scientific literature (i.e., PubMed abstracts) in a systematic way. OC-2-KB has two important modules which perform the acquisition of entities and the extraction then classification of relationships among these entities. We tested the OC-2-KB system on a data set with 23 manually annotated obesity and cancer PubMed abstracts and created a preliminary KB with 765 triples. We conducted a preliminary evaluation on this sample of triples and reported our evaluation results.

The incidence of obesity especially in Romanian population is presently escalating as a major nutrition and health problem. Clinicians aided by scientists are engaged in research approaches that include heredity aspects linked with behavior, education, applied nutrition studies and clinical therapies in order to prevent, control and reverse obesity. The common goal is to identify areas of basic and clinical research to understand aspects of human biology that may be considered as obesogenic. Regarding these approaches, recent discoveries in genetics, epigenetics and functional genomics, based on advancing technologies, are tools employed to prevent and treat obesity. The purpose of this article is to present the current knowledge of key components of the FTO gene role in the obesogenic system that links genetic, epigenetic and environmental, lifestyle/ diet nutritional and behavioral components and to describe the results obtained by genotyping and interviewing relevant selected groups of Romanian population. FTO rs9939609 genotyping was performed on a Romanian study group of 53 subjects (30 obese, 23 normal). Results have been analyzed in association with obesity parameters and comorbidities in order to identify this polymorphism's effect on body mass in our Caucasian cohort. At the same time, personal history of the subjects in correlation with the FTO genotypes provided important information on the FTO gene's influence on the feeding behavior and food selection of these individuals. In conclusion, the FTO rs9939609 polymorphism has been identified as a common gene variant in our Romanian Caucasian cohort, proving a high association with all the parameters of obesity and obesity comorbidities. The adherence to a Mediterranean diet is benefic for subjects with genetic predisposition for this disorder as long as it is kept for a long period of time along with sustained physical exercise. Association studies are an extremely important tool in understanding the

Obesity, particularly abdominal obesity, is currently considered a chronic low-grade inflammatory condition that plays an active role in the development of the pathophysiologic phenomena responsible for metabolic syndrome and cardiovascular disease through the secretion of proinflammatory adipokines and cytokines. In recent years clear genetic, pathogenic, and epidemiologic links have been established between psoriasis and obesity, with important implications for health. The relationship between the 2 conditions is probably bidirectional, with obesity predisposing to psoriasis and psoriasis favoring obesity. Obesity also has important implications in the treatment of psoriasis, such as a greater risk of adverse effects with conventional systemic drugs and reduced efficacy and/or increased cost with biologic agents, for which dosage should be adjusted to the patient's weight.

In most cases, obesity does not stem from a specific psychologic disturbance. Some obese people overeat, as do their family or their socio-professional peers, and this cannot be considered a pathologic behaviour. Many obese patients increase their energy intake when frustrated, anxious, or tired, like many normal individuals who enjoy a better weight regulation. But when obesity increases suddenly and/or severely in these circumstances, and in gross obesity, abnormal feeding behaviour is usually responsible: prandial or, more often extraprandial overeating (nibbling, gorging, binge eating, night eating, excess alcohol, carbohydrate craving). Serotoninergic mechanisms of the latter have focused wide interest. Conflicting situations and/or anxiety are usually a factor in child obesity. Deppreciated self-image and feelings of culpability, partly secondary to obesity itself and dietary failures often contribute to feeding disturbances, sometimes surreptitious, carrying a risk of vicious circle. But weight reduction itself, while improving self image, carries a risk of unmasking depressive tendencies, especially when too quick. Hence the importance of careful and comprehensive management.

Background In the United States, overweight/obesity among youth has reached epidemic proportions. The purpose of this project was to (1) examine primary care provider adherence to American Academy of Pediatrics guidelines; (2) compare adherence based on patients' weight classification, age, race, and gender; and (3) identify areas for improvement in health care delivery. Methods A retrospective chart audit and feedback quality improvement project was conducted with a stratified random sample of 175 charts of 6- to 19-year-olds seen for well-child visits. Frequencies of provider adherence were reported. χ(2) Analyses of weight classification, age, race, or gender influence on adherence was calculated. Results After discussion with the primary care providers, 5 areas were identified as priorities for change (diagnosis based on BMI, parental history of obesity, sleep assessment, endocrine assessment, and attendance of patients at the follow-up visit). Conclusion Cost-efficient, feasible strategies to improve provider adherence to recommendations for identification, prevention and management of childhood overweight and obesity were identified. © The Author(s) 2015.

Weight gain in pregnancy is physiological but if a woman is overweight prior to pregnancy, this will put both women and foetus at risk of adverse complications. Obesity can affect women at all the stages of pregnancy. Obese women can be a cause of reduced fertility as compared to a normal weight woman, and a typical example is of the Polycystic ovarian syndrome (PCOS). The incidence of Gestational Diabetes Mellitus ,hypertension and preeclamsia is 2-3 folds higher in obesity particularly with a BMI of> 30kg/m2. The chances of thromboembolism, miscarriage, Caesarian - section and stillbirth are increased as well. Perinatal mortality, increased chances of genetic disorders of the foetus and macrosomia are all increased with obesity. To avoid all these complications health education regarding healthy life style and diet with regular moderate intensity exercise is the cornerstone of the management.

Obesity prevalence in the United States appears to be leveling, but the reasons behind the plateau remain unknown. Mechanistic insights can be provided from a mathematical model. The objective of this study is to model known multiple population parameters associated with changes in body mass index (BMI) classes and to establish conditions under which obesity prevalence will plateau. A differential equation system was developed that predicts population-wide obesity prevalence trends. The model considers both social and nonsocial influences on weight gain, incorporates other known parameters affecting obesity trends, and allows for country specific population growth. The dynamic model predicts that: obesity prevalence is a function of birthrate and the probability of being born in an obesogenic environment; obesity prevalence will plateau independent of current prevention strategies; and the US prevalence of overweight, obesity, and extreme obesity will plateau by about 2030 at 28%, 32%, and 9% respectively. The US prevalence of obesity is stabilizing and will plateau, independent of current preventative strategies. This trend has important implications in accurately evaluating the impact of various anti-obesity strategies aimed at reducing obesity prevalence. Copyright © 2013 The Obesity Society.

Little is known about the suitability of three commonly used body mass index (BMI) classification systems for Indigenous youth. We estimated overweight and obesity prevalence among Cree youth of Eeyou Istchee according to three BMI classification systems, assessed the level of agreement between them, and evaluated their accuracy through body fat and cardiometabolic risk factors. Data on 288 youth (aged 8-17 years) were collected. Overweight and obesity prevalence were estimated with Centers for Disease Control and Prevention (CDC), International Obesity Task Force (IOTF) and World Health Organization (WHO) criteria. Agreement was measured with weighted kappa (κw). Associations with body fat and cardiometabolic risk factors were evaluated by analysis of variance. Obesity prevalence was 42.7% with IOTF, 47.2% with CDC, and 49.3% with WHO criteria. Agreement was almost perfect between IOTF and CDC (κw = 0.93), IOTF and WHO (κw = 0.91), and WHO and CDC (κw = 0.94). Means of body fat and cardiometabolic risk factors were significantly higher (P trend < 0.001) from normal weight to obesity, regardless of the system used. Youth considered overweight by IOTF but obese by CDC or WHO exhibited less severe clinical obesity. IOTF seems to be more accurate in identifying obesity in Cree youth.
Elevated systemic hepcidin and iron depletion in obese pre-menopausal females.

Little is known about the suitability of three commonly used body mass index (BMI) classification system for Indigenous children. This study aims to estimate overweight and obesity prevalence among school-aged Nunavik Inuit children according to International Obesity Task Force (IOTF), Centers for Disease Control and Prevention (CDC), and World Health Organization (WHO) BMI classification systems, to measure agreement between those classification systems, and to investigate whether BMI status as defined by these classification systems is associated with levels of metabolic and inflammatory biomarkers. Data were collected on 290 school-aged children (aged 8-14 years; 50.7% girls) from the Nunavik Child Development Study with data collected in 2005-2010. Anthropometric parameters were measured and blood sampled. Participants were classified as normal weight, overweight, and obese according to BMI classification systems. Weighted kappa (κw) statistics assessed agreement between different BMI classification systems, and multivariate analysis of variance ascertained their relationship with metabolic and inflammatory biomarkers. The combined prevalence rate of overweight/obesity was 26.9% (with 6.6% obesity) with IOTF, 24.1% (11.0%) with CDC, and 40.4% (12.8%) with WHO classification systems. Agreement was the highest between IOTF and CDC (κw = .87) classifications, and substantial for IOTF and WHO (κw = .69) and for CDC and WHO (κw = .73). Insulin and high-sensitivity C-reactive protein plasma levels were significantly higher from normal weight to obesity, regardless of classification system. Among obese subjects, higher insulin level was observed with IOTF. Compared with other systems, IOTF classification appears to be more specific to identify overweight and obesity in Inuit children.

Excess weight gain is the most significant, preventable cause of increased blood pressure (BP) in patients with primary (essential) hypertension and increases the risk for cardiovascular and renal diseases. In this review, we discuss the role of the brain melanocortin system in causing increased sympathetic activity in obesity and other forms of hypertension. In addition, we highlight potential mechanisms by which the brain melanocortin system modulates metabolic and cardiovascular functions. PMID:24789984

Obesity is a significant public health issue in the US constituting an independent risk factor for morbidity and mortality as well as complicating the management of other medical conditions. Yet, traditionally most physicians receive little training in evidence-based obesity interventions. Previous literature suggests many physicians believe they do not have effective tools to address obesity and/or that obesity management is not within their scope of practice. Given the new emphasis from NIH and AAFP urging physicians to conceptualize and treat obesity as a chronic medical condition, we examined obesity-related knowledge and practices among military and civilian primary care physicians. Results were similar across these two physician groups in suggesting many physicians still may be ill-prepared to manage obesity in the primary care setting. Implications for patient care and future research are discussed.

Young adults are underrepresented in standard behavioral weight loss trials, and evidence suggests that they differ from older adults on many weight related constructs. The aim of this review is to explore young adults’ attitudes toward obesity and weight management, with particular attention to those factors that may play a role in development of future treatment efforts. Both intrapersonal and interpersonal considerations unique to young adulthood are assessed; in addition, we examine young adults’ perceptions of specific weight-related behaviors such as dieting, physical activity, and self-weighing. Conclusions are consistent with other findings suggesting that weight management interventions should be adapted and designed specifically for this age group. PMID:26923688

Engaging youth from racial and ethnic minority communities as leaders for change is a potential strategy to mobilize support for addressing childhood obesity, but there are limited curricula designed to help youth understand the complex influences on obesity. Our aim was to develop and pilot test a systems science curriculum to elicit rural African American youth perspectives on childhood obesity and enhance their understanding of and support for obesity prevention solutions. The curriculum was designed so it could be integrated with existing positive youth development curricula that help youth advocate for and implement identified solutions. We conducted four workshop sessions with youth that engaged them in systems learning activities such as guided systems diagramming activities. The participants ( n = 21) completed validated surveys presession and postsession that assessed their causal attributions of obesity and support for obesity prevention policies. The youths' perception that environmental factors cause obesity increased ( p < .05), and perceptions that individual behavior and biology cause obesity did not change. Their support for policies that addressed food access and food pricing significantly increased ( p < .05). The youths' system diagrams elucidated links between multilevel factors such as personal attitudes, social influence, and the built environment, which provides important information for designing synergistic solutions. The changes we observed in youths' perceptions of obesity and support for policy changes have important implications for youths' interest and willingness to advocate for social and environmental changes in their community. The strategies have a promising role in supporting community mobilization to address childhood obesity.

Objective Obesity prevalence in the United States (US) appears to be leveling, but the reasons behind the plateau remain unknown. Mechanistic insights can be provided from a mathematical model. The objective of this study is to model known multiple population parameters associated with changes in body mass index (BMI) classes and to establish conditions under which obesity prevalence will plateau. Design and Methods A differential equation system was developed that predicts population-wide obesity prevalence trends. The model considers both social and non-social influences on weight gain, incorporates other known parameters affecting obesity trends, and allows for country specific population growth. Results The dynamic model predicts that: obesity prevalence is a function of birth rate and the probability of being born in an obesogenic environment; obesity prevalence will plateau independent of current prevention strategies; and the US prevalence of obesity, overweight, and extreme obesity will plateau by about 2030 at 28%, 32%, and 9%, respectively. Conclusions The US prevalence of obesity is stabilizing and will plateau, independent of current preventative strategies. This trend has important implications in accurately evaluating the impact of various anti-obesity strategies aimed at reducing obesity prevalence. PMID:23804487

Childhood obesity is one of the most critical public health problems in the world. It is associated with low neuromuscular function and postural deformities. Whether weight loss can improve postural stability and neuromuscular control, benefit daily activities, or prevent injury is unknown. Therefore, this study attempts to investigate the effect of a 6 month weight management program on postural stability and neuromuscular control among obese children. We will conduct a prospective, single-blind, randomized controlled trial with 120 prepubescent obese children. Participants will be randomly assigned to a weight management group or a control group. The weight management group will participate in a dietary and exercise program. The control group will receive health education. After the intervention, participants will be followed for 6 months with no active intervention. The primary and secondary outcomes will be assessed at the baseline, and after 6 months and 12 months. Primary outcome measures will include body weight, body height, body mass index, waist circumference, hip circumference, and body fat percentage. Secondary outcome measures will include three-dimensional functional biomechanics in different tasks, proprioception tests of the knee and ankle, neuromuscular response of the leg muscles, and muscle strength tests of the knee and ankle. Furthermore, adverse events will be recorded and analyzed. An intention-to-treat analysis will be performed if any participants withdraw from the trial. The important features of this trial include the randomization procedures and large sample size. This study attempts to estimate the effect of weight loss intervention on outcomes, including daily life function, postural stability, and neuromuscular control in prepubescent obese children. Therefore, our results can be useful for obese children, medical staff, and healthcare decision makers. Chinese Clinical Trial Registry ChiCTR-IOB-15005874.
Diet and exercise in management of obesity and overweight.
Fock, Kwong Ming; Khoo, Joan
2013-12-01
According to World Health Organization, in 2010 there were over 1 billion overweight adults worldwide with 400 million adults who were obese. Obesity is a major risk factor for diabetes, cardiovascular disease, musculoskeletal disorders, obstructive sleep apnea, and cancers (prostate, colorectal, endometrial, and breast). Obese people may present to the gastroenterologists with gastroesophageal reflux, non-alcoholic fatty liver, and gallstones. It is important, therefore, to recognize and treat obesity. The main cause of obesity is an imbalance between calories consumed and calories expended, although in a small number of cases, genetics and diseases such as hypothyroidism, Cushing's disease, depression, and use of medications such as antidepressants and anticonvulsants are responsible for fat accumulation in the body. The main treatment for obesity is dieting, augmented by physical exercise and supported by cognitive behavioral therapy. Calorie-restriction strategies are one of the most common dietary plans. Low-calorie diet refers to a diet with a total dietary calorie intake of 800-1500, while very low-calorie diet has less than 800 calories daily. These dietary regimes need to be balanced in macronutrients, vitamins, and minerals. Fifty-five percent of the dietary calories should come from carbohydrates, 10% from proteins, and 30% from fats, of which 10% of total fat consist of saturated fats. After reaching the desired body weight, the amount of dietary calories consumed can be increased gradually to maintain a balance between calories consumed and calories expended. Regular physical exercise enhances the efficiency of diet through increase in the satiating efficiency of a fixed meal, and is useful for maintaining diet-induced weight loss. A meta-analysis by Franz found that by calorie restriction and exercise, weight loss of 5-8.5 kg was observed 6 months after intervention. After 48 months, a mean of 3-6 kg was maintained. In conclusion, there is evidence
Obesity in Women: Insights for the Clinician.

As a leading cause of morbidity and mortality in the United States and worldwide, obesity is a disease that is frequently encountered in clinical practice today and requires a range of medical interventions. While obesity affects both men and women across all ages, multiple issues are particularly germane to women's health, particularly as obesity is more prevalent among women than men in the United States and obesity among women of reproductive health relates to the growing issue of childhood obesity. Discussed herein are the epidemiology and pathophysiology of obesity along with the impact of perinatal obesity on fetal programming. Guidance on screening and management of obesity through lifestyle intervention, pharmacologic therapy, and bariatric surgery, as well as avoidance of weight-promoting medications wherever possible, is elaborated. Particular attention is paid to the contribution of these modalities to weight loss as well as their impact on obesity-related comorbidities that affect a woman's overall health, such as type 2 diabetes and hypertension, and her reproductive and gynecologic health. With modest weight loss, women with obesity can achieve notable improvements in chronic medical conditions, fertility, pregnancy outcomes, and symptoms of pelvic floor disorders. Moreover, as children born to women after bariatric surgery-induced weight loss show improved metabolic outcomes, this demonstrates a role for maternal weight loss in reducing risk of development of metabolic disturbances in children. In light of the immense cost burden and mortality from obesity, it is important to emphasize the role of lifestyle intervention, pharmacologic management, and bariatric surgery for weight loss in clinical practice to mitigate the impact of obesity on women's health.

Intervention programs targeting parents to manage childhood overweight and obesity have emerged based on parents influence on the health behaviors of their children. The purpose of this review was to systematically evaluate intervention programs targeting parents to manage childhood overweight and obesity using the Reach, Efficacy, Adopt, Implementation, and Maintenance (RE-AIM) framework. There was a moderate risk of bias across all studies. The overall proportion of studies (n=7) reporting on each dimension of the RE-AIM framework ranged from 78.6% (reach) to 23.8% (maintenance). The majority of intervention programs demonstrated improvement in child BMI. However intervention programs did not reach families of diverse race/ethnicity, were provided by highly trained professionals, and demonstrated high attrition, thus limiting generalizability.

Novel and emerging approaches to combat adolescent obesity
Sharma, Manoj; Branscum, Paul
2010-01-01
Overweight and obesity continue to be health concerns facing today’s adolescent population. Along with metabolic and physical problems associated with obesity, today’s obese adolescents also face many psychological issues such as high rates of depression, anxiety, and social discrimination. Obesity is commonly recognized as having many causes, such as genetic, lifestyle and environmental. There are four major modalities for management of overweight and obesity in adolescents: dietary management, increasing physical activity, pharmacological therapy, and bariatric surgery. The purpose of this study was to conduct a review of novel and emerging approaches for preventing and managing adolescent obesity. It was found that while not always the case, theory driven approaches are being better utilized in newer interventions especially by those directed toward prevention. New theories that are being used are the theories of reasoned action, planned behavior, intervention mapping, and social marketing. Schools are found to be the most common place for such interventions, which is appropriate since virtually all children attend some form of private or public school. Limitations found in many studies include the underuse of process evaluations, the low number of studies attempted, environmental or policy changes, and that not all studies used a similar control group for comparison.

Pharmacological Treatment of Obesity in Children and Adolescents: Present and Future
Iughetti, Lorenzo; China, Mariachiara; Berri, Rossella; Predieri, Barbara
2011-01-01
The prevalence of overweight and obesity is increasing in children and adolescents worldwide raising the question on the approach to this condition because of the potential morbidity, mortality, and economic tolls. Dietetic and behavioral treatments alone have only limited success; consequently, discussion on strategies for treating childhood and adolescent obesity has been promoted. Considering that our knowledge on the physiological systems regulating food intake and body weight is considerably increased, many studies have underlined the scientific and clinical relevance of potential treatments based on management of peripheral or central neuropeptides signals by drugs. In this paper, we analyze the data on the currently approved obesity pharmacological treatment suggesting the new potential drugs. PMID:21197151

Examine associations among weight status, weight perception, and weight management practices of Supplemental Nutrition Assistance Program-Education (SNAP-Ed) participants in Georgia. Self-reported weight, height, and weight-related practices were assessed and analyzed in 270 SNAP-Ed participants. Almost three quarters of the sample self-reported overweight or obesity. Among overweight and obese subjects, 39% and 69%, respectively, accurately perceived themselves as overweight. More than half of the sample desired weight loss and 44% had attempted weight loss in the past year. Overweight/obese subjects who accurately perceived their weight were more likely to desire and to have attempted weight loss than those who under-perceived their weight. Approximately 58% of all subjects who had attempted to lose weight reported use of both methods suggested for weight loss: exercise and dietary changes. The high prevalence of self-reported overweight/obesity combined with a desire to lose weight among the study sample demonstrated the necessity to develop SNAP-Ed curricula emphasizing weight management.

Currently more than 1 billion adults are overweight (Sthula) and at least 300 million of them are clinically obese. Obesity leads to adverse metabolic effects on blood pressure, cholesterol, triglycerides, and insulin resistance. Present study was planned to assess the role of Agnimanthadi compound containing Agnimantha, Mustaka, Gomutra (cow's urine), and Eranda Patra Kshara and Vashpa Svedana (VS) (generalized steaming) in the management of obesity. 80 patients of Sthaulya (obesity) were selected out of which 67 completed the treatment and they were treated in two groups. Amongst these, 38 patients were treated with Agnimanthadi compound in the dose of 2 gram (four capsules of 500 mg) 3 times a day with lukewarm water before meal and remaining 29 patients were given VS only. The duration of treatment in both groups was 7 weeks with follow-up for 2 months after the completion of treatment. Analysis of the overall effects of both the groups showed that VS provided marked reduction in weight, body mass index, and other signs and symptoms in patients of Sthaulya in comparison to the Agnimanthadi treated group.
Role of Bupropion Plus Naltrexone for the Management of Obesity
Booth, Kemper; Clements, Jennifer N.
2016-01-01
Objective. The pharmacology, pharmacokinetics, efficacy, and safety of bupropion plus naltrexone for weight loss were reviewed. Data Sources. A MEDLINE search (1970 to November 2015) was conducted for English-language articles using specific MESH terms. Study Selection and Data Extraction. Published Phase 3 clinical trials with primary endpoints related to weight loss were included and critiqued in this review. Study Selection and Data Extraction. Five trials were retrieved and reviewed regarding the efficacy and safety of bupropion plus naltrexone among obese and overweight patients. Data Synthesis. Bupropion is a dopamine/norepinephrine reuptake inhibitor, and naltrexone is an opioid receptor antagonist. The combination of these agents has led to increased weight loss, compared to placebo, among overweight and obese patients with a body mass index (BMI) at or above 30 or BMI at or above 27 with a comorbid condition. The combination of bupropion and naltrexone can produce an average placebo-subtracted weight loss of 4.25% over 56 weeks. Gastrointestinal (ie, nausea, vomiting, constipation) and central nervous system adverse events (ie, headache, dizziness) were commonly reported, and there was a high dropout rate among participants. Conclusions. Bupropion plus naltrexone has demonstrated effective weight loss, in conjunction with lifestyle modifications, among overweight and obese patients with and without comorbidities. Bupropion plus naltrexone has not been studied among special patient populations, such as those with sleep apnea, osteoarthritis, or extreme BMIs. Additional clinical trials and postmarketing data will provide a better understanding of this medication for weight loss.
Anaesthesia in the obese child.
Philippi-Höhne, Claudia
2011-03-01
The incidence of childhood obesity ranges today from approximately 8% to 17%, and is an increasing issue in developed and developing countries. This disease will become increasingly significant in paediatric anaesthesia. Obese children not only have anaesthesia-relevant co-existing diseases, that are, asthma and hypertension, but also have a higher incidence of anaesthesia-related complication. This review covers current definition and some epidemiology of childhood obesity. It summarises potential co-morbidities and provides details for preoperative evaluation, anaesthetic management and prevention of perioperative complications.

This paper presents a system management methodology for building successful resource management systems that possess lifecycle effectiveness. This methodology is based on an analysis of the traditional practice of Systems Engineering Management as it applies to the development of resource management systems. The analysis produced fifteen significant findings presented as recommended adaptations to the traditional practice of Systems Engineering Management to accommodate system development when the requirements are incomplete, unquantifiable, ambiguous and dynamic. Ten recommended adaptations to achieve operational effectiveness when requirements are incomplete, unquantifiable or ambiguous are presented and discussed. Five recommended adaptations to achieve system extensibility when requirements are dynamic are also presented and discussed. The authors conclude that the recommended adaptations to the traditional practice of Systems Engineering Management should be implemented for future resource management systems and that the technology exists to build these systems extensibly.

With nearly 40% of U.S. adults obese, and childhood and adolescent rates rising, obesity and associated comorbidities are serious public health concerns with massive societal costs. Often, lifestyle interventions do not offer sufficient weight loss to improve health, requiring surgery and medications as adjunct management strategies. Here, we present a 4-month case study in which the sustained, low-dose, and constant administration of the thyroid receptor β selective agonist GC-1 (sobetirome) from a novel nanochannel membrane implant was assessed in an obese, pre-diabetic rhesus macaque. Dramatic loss of white adipose tissue in the abdomen from 36 to 18% was observed via magnetic resonance imaging in conjunction with normalized serum insulin and glycemia, with no signs of cardiotoxicity shown. The non-human primate study highlights sustained low-dose delivery of GC-1 from our minimally invasive subcutaneous implant as a valuable approach to induce weight loss and manage obesity and comorbidities, including type 2 diabetes.
Obesity Prevention and Weight Maintenance After Loss.
German, Alexander James
2016-09-01
Obesity is one of the most prevalent medical diseases in pets. Outcomes are often disappointing; many animals either fail to reach target weight or regain weight. This article discusses managing obesity, focusing on prevention. It gives guidance on establishing monitoring programs that use regular body weight and condition assessments to identify animals at risk of inappropriate weight gain, enabling early intervention. Weight management in obese animals is a lifelong process. Regular weight and body condition monitoring are key to identifying animals that rebound early, while continuing to feed a therapeutic weight loss diet can help prevent it from happening.

mediation role of BMI was identified in the relationship between social status and the variables of interest. This study focused on a sample of people from the general population. It confirmed previous results of others studies. All results gave a feeling of resignation and powerlessness which can seize obese individuals (especially when BMI increases). As a consequence, there is a need for more adapted weight management to achieve a genuine therapeutic alliance. Copyright © 2017. Published by Elsevier Masson SAS.
The effect of obesity, weight gain, and weight loss on asthma inception and control.
Forno, Erick; Celedón, Juan C
2017-04-01
There is ample and growing evidence that obesity increases the risk of asthma and morbidity from asthma. Here, we review recent clinical evidence supporting a causal link between obesity and asthma, and the mechanisms that may lead to 'obese asthma'. Although in some children obesity and asthma simply co-occur, those with 'obese asthma' have increased asthma severity, lower quality of life, and reduced medication response. Underlying mechanistic pathways may include anatomical changes of the airways such as obstruction and dysanapsis, systemic inflammation, production of adipokines, impaired glucose-insulin metabolism, altered nutrient levels, genetic and epigenetic changes, and alterations in the airway and/or gut microbiome. A few small studies have shown that weight loss interventions may lead to improvements in asthma outcomes, but thus far research on therapeutic interventions for these children has been limited. Obesity increases the risk of asthma - and worsens asthma severity or control - via multiple mechanisms. 'Obese asthma' is a complex, multifactorial phenotype in children. Obesity and its complications must be managed as part of the treatment of asthma in obese children.

N-3 Polyunsaturated Fatty Acids and Inflammation in Obesity: Local Effect and Systemic Benefit
Huang, Feiruo
2015-01-01
Overwhelming consensus emerges among countless evidences that obesity is characterized by a chronic low-grade inflammation in the adipose tissue (AT), which subsequently develops into a systemic inflammatory state contributing to obesity-associated diseases. N-3 Polyunsaturated fatty acids (n-3 PUFA), known as important modulators participating in inflammatory process, turn out to be an effective mitigating strategy dealing with local and systemic inflammation observed in obesity. Some of the effects of n-3 PUFA are brought about by regulation of gene expression through interacting with nuclear receptors and transcription factors; other effects are elicited by modulation of the amount and type of mediator derived from PUFAs. The metabolic effects of n-3 PUFA mainly result from their interactions with several organ systems, not limited to AT. Notably, the attenuation of inflammation in hard-hit AT, in turn, contributes to reducing circulating concentrations of proinflammatory cytokines and detrimental metabolic derivatives, which is beneficial for the function of other involved organs. The present review highlights a bridging mechanism between n-3 PUFA-mediated inflammation relief in AT and systemic benefits. PMID:26339623

Obesity and Dyslipidemia in South Asians
Misra, Anoop; Shrivastava, Usha
2013-01-01
Obesity and dyslipidemia are emerging as major public health challenges in South Asian countries. The prevalence of obesity is more in urban areas than rural, and women are more affected than men. Further, obesity in childhood and adolescents is rising rapidly. Obesity in South Asians has characteristic features: high prevalence of abdominal obesity, with more intra-abdominal and truncal subcutaneous adiposity than white Caucasians. In addition, there is greater accumulation of fat at “ectopic” sites, namely the liver and skeletal muscles. All these features lead to higher magnitude of insulin resistance, and its concomitant metabolic disorders (the metabolic syndrome) including atherogenic dyslipidemia. Because of the occurrence of type 2 diabetes, dyslipidemia and other cardiovascular morbidities at a lower range of body mass index (BMI) and waist circumference (WC), it is proposed that cut-offs for both measures of obesity should be lower (BMI 23–24.9 kg/m2 for overweight and ≥25 kg/m2 for obesity, WC ≥80 cm for women and ≥90 cm for men for abdominal obesity) for South Asians, and a consensus guideline for these revised measures has been developed for Asian Indians. Increasing obesity and dyslipidemia in South Asians is primarily driven by nutrition, lifestyle and demographic transitions, increasingly faulty diets and physical inactivity, in the background of genetic predisposition. Dietary guidelines for prevention of obesity and diabetes, and physical activity guidelines for Asian Indians are now available. Intervention programs with emphasis on improving knowledge, attitude and practices regarding healthy nutrition, physical activity and stress management need to be implemented. Evidence for successful intervention program for prevention of childhood obesity and for prevention of diabetes is available for Asian Indians, and could be applied to all South Asian countries with similar cultural and lifestyle profiles.

Obesity and cancer: inflammation bridges the two
Kolb, Ryan; Sutterwala, Fayyaz S.; Zhang, Weizhou

Obesity is a growing public health problem and affects 35% US adults. Obesity increases the risk of many cancer types and is associated with poor outcomes. Clinical management of cancer patients has been essentially the same between normal weight and obese individuals. Understanding causal mechanisms by which obesity drives cancer initiation and progression is essential for the development of novel precision therapy for obese cancer patients. One caveat is that various mechanisms have been proposed for different cancer types for their progression under obesity. Since obesity is known to have global impact on inflammation, here we will summarize recent literature and discuss the potential of inflammation being the common causal mechanism to promote cancer promotion across cancer types.

In the United States, more than 50 million people have blood pressure at or above 120/80 mm Hg. All components of cardiorenal metabolic syndrome (CRS) are linked to metabolic abnormalities and obesity. A major driver for CRS is obesity. Current estimates show that many of those with hypertension and CRS show some degree of systemic and cardiovascular insulin resistance. Several pathophysiologic factors participate in the link between hypertension and CRS. This article updates recent literature with a focus on the function of insulin resistance, obesity, and renin angiotensin aldosterone system-mediated oxidative stress on endothelial dysfunction and the pathogenesis of hypertension.

Obesity and weight management in the elderly: a focus on men.
Han, T S; Wu, F C W; Lean, M E J
2013-08-01
The rising rate of overweight/obesity among the ever-growing ageing population is imposing massive and rapidly changing burdens of ill health. The observation that the BMI value associated with the lowest relative mortality is slightly higher in older than in younger adults, mainly through its reduced impact on coronary heart disease, has often been misinterpreted that obesity is not as harmful in the elderly, who suffer a large range of disabling consequences of obesity. All medical consequences of obesity are multi-factorial and most alleviated by modest, achievable weight loss (5-10 kg) with an evidence-based maintenance strategy. But severe obesity, e.g. BMI >40 may demand greater weight loss e.g. >15 kg to reverse type 2 diabetes. Since relatively reduced physical activity and reduced muscle mass (sarcopenic obesity) are common in the elderly, combining exercise and modest calorie restriction optimally reduces fat mass and preserves muscle mass - age presents no obstacle and reducing polypharmacy is a valuable outcome. The currently licensed drug orlistat has no age-related hazards and is effective in a low fat diet, but the risks from bariatric surgery begin to outweigh benefits above age 60. For the growing numbers of obese elderly with diabetes, the glucagon-like peptide-1 (GLP-1) receptor analogue liraglutide appears a safe way to promote and maintain substantial weight loss. Obesity and sarcopenia should be prevented from younger age and during life-transitions including retiral to improve future health outcomes and quality of life, with a focus on those in "obese families".

Interactions between pre-existing differences in mesolimbic function and neuroadaptations induced by consumption of fatty, sugary foods are thought to contribute to human obesity. This study examined basal and cocaine-induced changes in striatal neurotransmitter levels without diet manipulation and D2 /D3 dopamine receptor-mediated transmission prior to and after consumption of "junk-foods" in obesity-prone and obesity-resistant rats. Microdialysis and liquid chromatography-mass spectrometry were used to determine basal and cocaine-induced changes in neurotransmitter levels in real time with cocaine-induced locomotor activity. Sensitivity to the D2 /D3 dopamine receptor agonist quinpirole was examined before and after restricted junk-food exposure. Selectively bred obesity-prone and obesity-resistant rats were used. Cocaine-induced locomotion was greater in obesity-prone rats versus obesity-resistant rats prior to diet manipulation. Basal and cocaine-induced increases in dopamine and serotonin levels did not differ. Obesity-prone rats were more sensitive to the D2 receptor-mediated effects of quinpirole, and junk-food produced modest alterations in quinpirole sensitivity in obesity-resistant rats. These data show that mesolimbic systems differ prior to diet manipulation in susceptible versus resistant rats, and that consumption of fatty, sugary foods produce different neuroadaptations in these populations. These differences may contribute to enhanced food craving and an inability to limit food intake in susceptible individuals. © 2016 The Obesity Society.

Interventions targeting parenting focused modifiable factors to prevent obesity and promote healthy growth in the first 1000 days of life are needed. Scale-up of interventions to global populations is necessary to reverse trends in weight status among infants and toddlers, and large scale dissemination will require understanding of effective strategies. Utilizing nutrition education theories, this paper describes the design of a digital-based nutrition guidance system targeted to first-time mothers to prevent obesity during the first two years. The multicomponent system consists of scientifically substantiated content, tools, and telephone-based professional support delivered in an anticipatory and sequential manner via the internet, email, and text messages, focusing on educational modules addressing the modifiable factors associated with childhood obesity. Digital delivery formats leverage consumer media trends and provide the opportunity for scale-up, unavailable to previous interventions reliant on resource heavy clinic and home-based counseling. Designed initially for use in the United States, this system's core features are applicable to all contexts and constitute an approach fostering healthy growth, not just obesity prevention. The multicomponent features, combined with a global concern for optimal growth and positive trends in mobile internet use, represent this system's future potential to affect change in nutrition practice in developing countries.

Scoping review report: obesity in older adults.
Decaria, J E; Sharp, C; Petrella, R J

Obesity is associated with an increased risk for early death, heart disease and stroke, disability and several other comorbidities. Although there is concern about the potential burden on health-care services with the aging demographic and the increasing trend of obesity prevalence in older adults, evidence on which to base management strategies is conflicting for various reasons. The analytic framework for this review is based on a scoping review methodology, and was conducted to examine what is known about the diagnosis, treatment and management of obesity in older adults. A total of 492 relevant research articles were identified using PubMed, Scirus, EBSCO, Clinicaltrials.gov, Cochrane Reviews and Google Scholar. The findings of this review indicate that the current WHO (World Health Organization)-recommended body mass index, waist circumference and waist-to-hip ratio obesity thresholds for the general adult population may not be appropriate for older adults. Alternatively, weight change or physical fitness may be more useful measures of mortality and health risk in obese older adults. Furthermore, although obesity in older adults is associated with several disorders that increase functional disability, epidemiological evidence suggests that obesity is protective against mortality in seniors. Consequently, the trend toward increasing prevalence of obesity in older adults will lead to an increase in unhealthy life years and health-care costs. The findings from this review also suggest that treatment strategies for obese older adults should focus on maintaining body weight and improving physical fitness and function rather than weight loss, and that a combination of aerobic and resistance exercise appears to be the most effective strategy. In conclusion, this review demonstrates the need for more research to clarify the definition of obesity in older adults, to establish criteria for evaluating when to treat older adults for obesity, and to develop effective
Obesity and weight management at menopause.
Proietto, Joseph
2017-06-01
Many women report gaining weight as they transition through menopause. For most, the weight gain is modest and can be reduced with a conscious effort to limit energy intake and increase energy expenditure. However, many women who are already overweight and obese will gain more weight as they approach menopause. The aims of this paper are to explain the reasons for menopausal weight gain and to detail a method for achieving and sustaining a substantial weight loss. Weight gain during menopause is predominantly due to a reduction in spontaneous activity. For women who are lean, advice about controlling energy intake and increasing physical activity may be all that is required to prevent weight gain. For women who are overweight and obese rapid weight loss is best achieved with the help of a very low energy diet. This must be followed by lifelong behaviour modification with or without the help of hunger-suppressing pharmacotherapy.
Obesity and fractures in postmenopausal women.
Compston, Juliet
2015-07-01
Although obesity was previously believed to be protective against fracture, there is now evidence that a significant proportion of fractures in postmenopausal women occur in those who are obese. In this article the epidemiology, pathophysiology and clinical management of fractures in obese postmenopausal women are discussed with particular focus on the site specificity of the effect of BMI on fracture, interactions between fat and bone and risk assessment and prevention of fractures. There is similarity in many respects between risk factors for fracture in obese and nonobese women, although falls may play a particularly important role in the obese. Treatment rates in obese postmenopausal women with fracture are currently low, and further studies are required to establish effective preventive strategies. Fractures in obese postmenopausal women contribute significantly to the overall fracture burden in this population. Further work is required to establish their pathophysiology and to develop effective preventive strategies.

The coordinative pattern is an important feature of locomotion that has been studied in a number of pathologies. It has been observed that adaptive changes in coordination patterns are due to both external and internal constraints. Obesity is characterized by the presence of excess mass at pelvis and lower-limb areas, causing mechanical constraints that central nervous system could manage modifying the physiological interjoint coupling relationships. Since an altered coordination pattern may induce joint diseases and falls risk, the aim of this study was to analyze whether and how coordination during walking is affected by obesity. We evaluated interjoint coordination during walking in 25 obese subjects as well as in a control group. The time-distance parameters and joint kinematics were also measured. When compared with the control group, obese people displayed a substantial similarity in joint kinematic parameters and some differences in the time-distance and in the coupling parameters. Obese subjects revealed higher values in stride-to-stride intrasubjects variability in interjoint coupling parameters, whereas the coordinative mean pattern was unaltered. The increased variability in the coupling parameters is associated with an increased risk of falls and thus should be taken into account when designing treatments aimed at restoring a normal locomotion pattern.

Adipocytes properties and crosstalk with immune system in obesity-related inflammation.
Maurizi, Giulia; Della Guardia, Lucio; Maurizi, Angela; Poloni, Antonella
2018-01-01
Obesity is a condition likely associated with several dysmetabolic conditions or worsening of cardiovascular and other chronic disturbances. A key role in this mechanism seem to be played by the onset of low-grade systemic inflammation, highlighting the importance of the interplay between adipocytes and immune system cells. Adipocytes express a complex and highly adaptive biological profile being capable to selectively activate different metabolic pathways in order to respond to environmental stimuli. It has been demonstrated how adipocytes, under appropriate stimulation, can easily differentiate and de-differentiate thereby converting themselves into different phenotypes according to metabolic necessities. Although underlying mechanisms are not fully understood, growing in adipocyte size and the inability of storing triglycerides under overfeeding conditions seem to be crucial for the switching to a dysfunctional metabolic profile, which is characterized by inflammatory and apoptotic pathways activation, and by the shifting to pro-inflammatory adipokines secretion. In obesity, changes in adipokines secretion along with adipocyte deregulation and fatty acids release into circulation contribute to maintain immune cells activation as well as their infiltration into regulatory organs. Over the well-established role of macrophages, recent findings suggest the involvement of new classes of immune cells such as T regulatory lymphocytes and neutrophils in the development inflammation and multi systemic worsening. Deeply understanding the pathways of adipocyte regulation and the de-differentiation process could be extremely useful for developing novel strategies aimed at curbing obesity-related inflammation and related metabolic disorders. © 2017 Wiley Periodicals, Inc.

There is increasing recognition that low-intensity physical activities of daily life play an important role in achieving energy balance and that their societal erosion through substitution with sedentary (mostly sitting) behaviors, whether occupational or for leisure, impact importantly on the obesity epidemic. This has generated considerable interest for better monitoring, characterizing, and promoting countermeasures to sedentariness through a plethora of low-level physical activities (e.g., active workstations, standing desks, sitting breaks), amid the contention that altering posture allocation (lying, sitting, standing) can modify energy expenditure to impact upon body weight regulation and health. In addressing this contention, this paper first revisits the past and more recent literature on postural energetics, with particular emphasis on potential determinants of the large inter-individual variability in the energy cost of standing and the impact of posture on fat oxidation. It subsequently analyses the available data pertaining to various strategies by which posture allocations, coupled with light physical activity, may increase energy expenditure beyond the sedentary threshold, and their relevance as potential targets for obesity management.

Targeting obesity-related adipose tissue dysfunction to prevent cancer development and progression
Gucalp, Ayca; Iyengar, Neil M.; Hudis, Clifford A.; Dannenberg, Andrew J.
2016-01-01
The incidence of obesity, a leading modifiable risk factor for common solid tumors, is increasing. Effective interventions are needed to minimize the public health implications of obesity. Although the mechanisms linking increased adiposity to malignancy are incompletely understood, growing evidence points to complex interactions among multiple systemic and tissue-specific pathways including inflamed white adipose tissue. The metabolic and inflammatory consequences of white adipose tissue dysfunction collectively provide a plausible explanation for the link between overweight/obesity and carcinogenesis. Gaining a better understanding of these underlying molecular pathways and developing risk assessment tools that identify at-risk populations will be critical in implementing effective and novel cancer prevention and management strategies.

Genetics and epigenetics of obesity.
Herrera, Blanca M; Keildson, Sarah; Lindgren, Cecilia M
2011-05-01
Obesity results from interactions between environmental and genetic factors. Despite a relatively high heritability of common, non-syndromic obesity (40-70%), the search for genetic variants contributing to susceptibility has been a challenging task. Genome wide association (GWA) studies have dramatically changed the pace of detection of common genetic susceptibility variants. To date, more than 40 genetic variants have been associated with obesity and fat distribution. However, since these variants do not fully explain the heritability of obesity, other forms of variation, such as epigenetics marks, must be considered. Epigenetic marks, or "imprinting", affect gene expression without actually changing the DNA sequence. Failures in imprinting are known to cause extreme forms of obesity (e.g. Prader-Willi syndrome), but have also been convincingly associated with susceptibility to obesity. Furthermore, environmental exposures during critical developmental periods can affect the profile of epigenetic marks and result in obesity. We review the most recent evidence for genetic and epigenetic mechanisms involved in the susceptibility and development of obesity. Only a comprehensive understanding of the underlying genetic and epigenetic mechanisms, and the metabolic processes they govern, will allow us to manage, and eventually prevent, obesity.

Despite emphasis of recent guidelines on multidisciplinary teams for collaborative weight management, little is known about non-physician health professionals' perspectives on obesity, their weight management training, and self-efficacy for obesity care. To evaluate differences in health professionals' perspectives on (1) the causes of obesity; (2) training in weight management; and (3) self-efficacy for providing obesity care. Data were obtained from a cross-sectional Internet-based survey of 500 U.S. health professionals from nutrition, nursing, behavioral/mental health, exercise, and pharmacy (collected from January 20 through February 5, 2014). Inferences were derived using logistic regression adjusting for age and education (analyzed in 2014). Nearly all non-physician health professionals, regardless of specialty, cited individual-level factors, such as overconsumption of food (97%), as important causes of obesity. Nutrition professionals were significantly more likely to report high-quality training in weight management (78%) than the other professionals (nursing, 53%; behavioral/mental health, 32%; exercise, 50%; pharmacy, 47%; p<0.05). Nutrition professionals were significantly more likely to report high confidence in helping obese patients achieve clinically significant weight loss (88%) than the other professionals (nursing, 61%; behavioral/mental health, 51%; exercise, 52%; pharmacy, 61%; p<0.05), and more likely to perceive success in helping patients with obesity achieve clinically significant weight loss (nutrition, 81%; nursing, behavioral/mental health, exercise, and pharmacy, all <50%; p<0.05). Nursing, behavioral/mental health, exercise, and pharmacy professionals may need additional training in weight management and obesity care to effectively participate in collaborative weight management models.

The objective was to determine whether obesity screening and weight management program participation and outcomes are equitable for individuals with serious mental illness (SMI) and depressive disorder (DD) compared to those without SMI/DD in Veterans Health Administration (VHA), the largest integrated US health system, which requires obesity screening and offers weight management to all in need. We used chart-reviewed, clinical and administrative VHA data from fiscal years 2010-2012 to estimate obesity screening and participation in the VHA's weight management program (MOVE!) across groups. Six- and 12-month weight changes in MOVE! participants were estimated using linear mixed models adjusted for confounders. Compared to individuals without SMI/DD, individuals with SMI or DD were less frequently screened for obesity (94%-94.7% vs. 95.7%) but had greater participation in MOVE! (10.1%-10.4% vs. 7.4%). MOVE! participants with SMI or DD lost approximately 1 lb less at 6 months. At 12 months, average weight loss for individuals with SMI or neither SMI/DD was comparable (-3.5 and -3.3 lb, respectively), but individuals with DD lost less weight (mean=-2.7 lb). Disparities in obesity screening and treatment outcomes across mental health diagnosis groups were modest. However, participation in MOVE! was low for every group, which limits population impact.

Anti-Obesity Pharmacotherapy: New Drugs and Emerging Targets
Kim, Gilbert W.; Lin, Jieru E.; Blomain, Erik S.; Waldman, Scott A.
2014-01-01
Obesity is a growing pandemic and related health and economic costs are staggering. Pharmacotherapy partnered with lifestyle modifications form the core of current strategies to reduce the burden of this disease and its sequelae. However, therapies targeting weight loss have a significant history of safety risks, including cardiovascular and psychiatric events. Here, evolving strategies for developing anti-obesity therapies, including targets, mechanisms, and developmental status are highlighted. Progress in this field is underscored by Belviq® (lorcaserin) and Qsymia® (phentermine/topiramate), the first agents in more than 10 years to achieve regulatory approval for chronic management weight in obese patients. On the horizon, novel insights in metabolism and energy homeostasis reveal cGMP signaling circuits as emerging targets for anti-obesity pharmacotherapy. These innovations in molecular discovery may elegantly align with practical off-the-shelf approaches leveraging existing approved drugs that modulate cGMP levels for the management of obesity.

Attrition in pediatric weight management is a substantial problem. This study examined factors associated with short- and long-term attrition from a lifestyle and behavioral intervention for parents of children with overweight or obesity. Fifty-two families with children ages 6 to 12 years old and body mass index at or above the 85th percentile participated in a randomized controlled trial focused on parents, comparing parent-based cognitive behavioral therapy with parent-based psychoeducation for pediatric weight management. We examined program attrition using two clinical phases of the intervention: short-term and long-term attrition, modeled using the general linear model. Predictors included intervention type, child/parent weight status, sociodemographic factors, and health of the family system. Higher self-assessed health of the family system was associated with lower short-term attrition; higher percentage of intervention sessions attended by parents was associated with lower long-term attrition. Different variables were significant in our short- and long-term models. Attrition might best be conceptualized based on short- and long-term phases of clinical, parent-based interventions for pediatric weight management.

Existing evidence on the role of sociodemographic variables as risk factors for overweight and obesity in school-aged children is inconsistent. Furthermore, findings seem to be influenced by the obesity definition applied. Therefore, this study aimed to investigate if school sociodemographic indicators were associated with weight status in Irish primary schoolchildren and whether this association was sensitive to different obesity classification systems. A nationally representative cross-sectional sample of 7542 Irish children (53.9% girls), mean age 10.4 (±1.2SD) years, participating in the Childhood Obesity Surveillance Initiative in the 2010, 2012/2013 or 2015/2016 waves were included. Height, weight and waist circumference were objectively measured. Five definitions of obesity were employed using different approaches for either body mass index (BMI) or abdominal obesity. Associations between overweight and obesity and sociodemographic variables were investigated using adjusted multilevel logistic regression analyses. Children attending disadvantaged schools were more likely to be overweight and obese than their peers attending non-disadvantaged schools, regardless of the obesity classification system used. Associations remained significant for the BMI-based obesity definitions when the sample was stratified by sex and age group, except for boys aged 8-10.5 years. Only boys aged ≥10.5 years in disadvantaged schools had higher odds of abdominal obesity (UK 1990 waist circumference growth charts: OR = 1.56, 95%CI = 1.09-2.24; waist-to-height ratio: OR = 1.78, 95%CI = 1.14-2.79) than those in non-disadvantaged schools. No associations were observed for school urbanisation level. School socioeconomic status was a strong determinant of overweight and obesity in Irish schoolchildren, and these associations were age- and sex-dependent. School location was not associated with overweight or obesity. There remains a need to intervene with school

Most US adults are overweight or obese. Understanding differences in obesity prevalence across subpopulations could facilitate the development and dissemination of weight management services. To inform Veterans Health Administration (VHA) weight management initiatives, we describe obesity prevalence among subpopulations of VHA patients. Cross-sectional descriptive analyses of fiscal year 2014 (FY2014) national VHA administrative and clinical data, stratified by gender. Differences ≥5% higher than the population mean were considered clinically significant. Veteran VHA primary care patients with a valid weight within ±365 days of their first FY2014 primary care visit, and a valid height (98% of primary care patients). We used VHA vital signs data to ascertain height and weight and calculate body mass index, and VHA outpatient, inpatient, and fee basis data to identify sociodemographic- and comorbidity-based subpopulations. Among nearly five million primary care patients (347,112 women, 4,567,096 men), obesity prevalence was 41% (women 44%, men 41%), and overweight prevalence was 37% (women 31%, men 38%). Across the VHA's 140 facilities, obesity prevalence ranged from 28% to 49%. Among gender-stratified subpopulations, obesity prevalence was high among veterans under age 65 (age 18-44: women 40%, men 46%; age 45-64: women 49%, men 48%). Obesity prevalence varied across racial/ethnic and comorbidity subpopulations, with high obesity prevalence among black women (51%), women with schizophrenia (56%), and women and men with diabetes (68%, 56%). Overweight and obesity are common among veterans served by the VHA. VHA's weight management initiatives have the potential to avert long-term morbidity arising from obesity-related conditions. High-risk groups-such as black women veterans, women veterans with schizophrenia, younger veterans, and Native Hawaiian/Other Pacific Islander and American Indian/Alaska Native veterans-may require particular attention to ensure that

Parturients with super-morbid obesity, defined as body mass index greater than 50kg/m(2), represent a growing segment of patients who require anesthetic care for labor and delivery. Severe obesity and its comorbid conditions place the parturient and fetus at greater risk for pregnancy complications and cesarean delivery, as well as surgical and anesthetic complications. The surgical approach for cesarean delivery in these patients may require a supra-umbilical vertical midline incision due to a large pannus. The dense T4-level of spinal anesthesia can cause difficulties with ventilation for the obese patient during the procedure, which can be prolonged. Patients also may have respiratory complications in the postoperative period due to pain from the incision. We describe the anesthetic management of three parturients with body mass index ranging from 73 to 95kg/m(2) who had a cesarean delivery via a supra-umbilical vertical midline incision. Continuous lumbar spinal and low thoracic epidural catheters were placed in each patient for intraoperative anesthesia and postoperative analgesia, respectively. Continuous spinal catheters were dosed with incremental bupivacaine boluses to achieve surgical anesthesia. In one case, the patient required respiratory support with non-invasive positive pressure ventilation. Two cases were complicated by intraoperative hemorrhage. All patients had satisfactory postoperative analgesia with a thoracic epidural infusion. None suffered postoperative respiratory complications or postdural puncture headache. The use of a continuous lumbar spinal catheter and a low thoracic epidural provides several advantages in the anesthetic management of super-morbidly obese parturients for cesarean delivery.

Obesity Prevention in Older Adults.
Volpe, Stella Lucia; Sukumar, Deeptha; Milliron, Brandy-Joe
2016-06-01
The number of older adults living in the USA, 65 years of age and older, has been steadily increasing. Data from the National Health and Nutrition Examination Survey (NHANES), 2007-2010, indicate that more than one-third of older adults, 65 years of age and older, were obese. With the increased rate of obesity in older adults, the purpose of this paper is to present research on different methods to prevent or manage obesity in older adults, namely dietary interventions, physical activity interventions, and a combination of dietary and physical activity interventions. In addition, research on community assistance programs in the prevention of obesity with aging will be discussed. Finally, data on federal programs for older adults will also be presented.

Although postmenopausal associated disorders are important public health problems worldwide, to date limited studies evaluated the endothelial function and systemic inflammation response to weight loss in obese postmenopausal women. This study was done to evaluate the endothelial function and systemic inflammation response to weight loss in obese postmenopausal Saudi women. Eighty postmenopausal obese Saudi women (mean age 52.64±6.13 year) participated in two groups: Group (A) received aerobic exercise on treadmill and diet whereas, group (B) received no intervention. Markers of inflammation and endothelial function were measured before and after 3 months at the end of the study. The values of body mass index(BMI), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), C-reactive protein (CRP), inter-cellular adhesion molecule (ICAM-1), vascular cell adhesion molecule (VCAM-1) and plasminogen activator inhibitor-1 activity (PAI-1:Ac) were significantly decreased in group (A), while changes were not significant in group (B). Also, there were significant differences between mean levels of the investigated parameters in group (A) and group (B) after treatment. Weight loss ameliorates inflammatory cytokines and markers of endothelial function in obese postmenopausal Saudi women.

Obesity is a serious public health problem and being multifactorial is difficult to tackle. Since the intestinal ecosystem's homeostasis is, at least partially, diet-dependent, its modulation may be triggered by food components that are designed to exert a modulatory action leading to a health-promoting effect. Milk whey proteins, are considered as such promising factors since they influence satiation as well as body weight and constitute the source of biologically active peptides which may modulate health status locally and systemically. This way, whey proteins are associated with obesity. Therefore, this paper is aimed at the estimation of the impact of whey proteins using a commercially available whey protein isolate on the physiological response of mice with diet-induced obesity. The physiological response was evaluated on the local-intestinal level, scrutinizing intestinal microbiota as one of the important factors in obesity and on the systemic level, analyzing the response of the organism. Whey proteins brought about the decrease of the fat mass with a simultaneous increase of the lean mass of animals with diet induced obesity, which is a promising, health-promoting effect. Whey proteins also proved to act beneficially helping restore the number of beneficial bifidobacteria in obese animals and decreasing the calorie intake and fat mass as well as the LDL level. Overall, supplementation of the high fat diet with whey proteins acted locally by restoration of the intestinal ecosystem, thus preventing dysbiosis and its effects and also acted systemically by strengthening the organism increasing the lean mass and thus hindering obesity-related detrimental effects.

Ghrelin-system components [native ghrelin, In1-ghrelin, Ghrelin-O-acyltransferase enzyme (GOAT) and receptors (GHS-Rs)] are expressed in a wide variety of tissues, including the pancreas, where they exert different biological actions including regulation of neuroendocrine secretions, food intake and pancreatic function. The expression of ghrelin system is regulated by metabolic conditions (fasting/obesity) and is associated with the progression of obesity and insulin resistance. Cortistatin (CORT), a neuropeptide able to activate GHS-R, has emerged as an additional link in gut-brain interplay. Indeed, we recently reported that male CORT deficient mice (cort-/-) are insulin-resistant and present a clear dysregulation in the stomach ghrelin-system. The present work was focused at analyzing the expression pattern of ghrelin-system components at pancreas level in cort-/- mice and their control littermates (cort +/+) under low- or high-fat diet. Our data reveal that all the ghrelin-system components are expressed at the mouse pancreatic level, where, interestingly, In1-ghrelin was expressed at higher levels than native-ghrelin. Thus, GOAT mRNA levels were significantly lower in cort-/- mice compared with controls while native ghrelin, In1-ghrelin and GHS-R transcript levels remained unaltered under normal metabolic conditions. Moreover, under obese condition, a significant increase in pancreatic expression of native-ghrelin, In1-ghrelin and GHS-R was observed in obese cort+/+ but not in cort-/- mice. Interestingly, insulin expression and release was elevated in obese cort+/+, while these changes were not observed in obese cort-/- mice. Altogether, our results indicate that the ghrelin-system expression is clearly regulated in the pancreas of cort+/+ and cort -/- under normal and/or obesity conditions suggesting that this system may play relevant roles in the endocrine pancreas. Most importantly, our data demonstrate, for the first time, that endogenous CORT is essential
Obese children experience higher plantar pressure and lower foot sensitivity than non-obese.

Children obesity is a risk factor for several dysfunctions and diseases, with negative effects on the morphology of the locomotor system, plantar pressure and body stability. A relationship between postural control and sensorimotor information has been assumed. However, there is few data on the effects of children obesity on the availability of sensorial information from the foot during standing. Twenty obese and twenty non-obese children were evaluated for foot sensitivity and plantar pressure during unipedal and bipedal stance. Data were compared between obese and non-obese participants, between foot regions and between legs. Obese children experiences higher plantar pressure and have lower foot sensitivity than non-obese. Additionally, obese children had similar sensitivity for different foot regions, as compared to the non-obese. Children obesity negatively influences foot sensitivity. Bipedal stance seemed more sensitive to differentiate between obese and non-obese. Higher plantar pressure and lower foot sensitivity in obese children may affect performance of weight bearing activities, contribute to higher risk of foot injuries and have potential implication for children footwear design and clinical physical examination.

The food environment plays an important and often dominant role in food choice, eating patterns, and ultimately, energy intake. The Obesity Society and the American Society for Nutrition jointly sponsored a series of reviews on topics of interest to both memberships. The goal was to consider the state of understanding on selected issues related to the food environment and obesity and to identify key knowledge gaps. The first article (not necessarily of importance) targeted energy density (ED) and focuses on the role of ED in the regulation of energy intake and body weight. It offers recommendations for prioritizing research. The second article addresses economic factors and examines food and beverage purchases as a function of price changes. It concludes that targeted food taxes and subsidies alone are unlikely to substantially affect obesity. The third article concerns sweetened beverages and points out the difficulty in establishing the strength of the association between intake of sugar-sweetened beverages and weight gain and obesity. In the fourth article, the contributions of palatability and variety to eating behavior and weight are reviewed. Article five explores the influence of portion size on energy intake and weight management. It finds that consumers generally tend to eat proportionally more as portion size increases. The sixth article focuses on the efficacy and effectiveness of eating frequency manipulations for body weight management and finds that such manipulations have consistently yielded null results. Finally, article seven identifies several limitations of the existing literature regarding neighborhood access to healthy foods. This series of reviews addresses important questions regarding the contribution of the food environment to obesity. Independent of physiological/genetic determinants, factors such as ED, cost, food form, palatability, variety, portion size, eating frequency, and access to healthy food are each evaluated for their role in
Obesity and health system reform: private vs. public responsibility.
Yang, Y Tony; Nichols, Len M
2011-01-01
Obesity is a particularly vexing public health challenge, since it not only underlies much disease and health spending but also largely stems from repeated personal behavioral choices. The newly enacted comprehensive health reform law contains a number of provisions to address obesity. For example, insurance companies are required to provide coverage for preventive-health services, which include obesity screening and nutritional counseling. In addition, employers will soon be able to offer premium discounts to workers who participate in wellness programs that emphasize behavioral choices. These policies presume that government intervention to reduce obesity is necessary and justified. Some people, however, argue that individuals have a compelling interest to pursue their own health and happiness as they see fit, and therefore any government intervention in these areas is an unwarranted intrusion into privacy and one's freedom to eat, drink, and exercise as much or as little as one wants. This paper clarifies the overlapping individual, employer, and social interest in each person's health generally to avoid obesity and its myriad costs in particular. The paper also explores recent evidence on the impact of government interventions on obesity through case studies on food labeling and employer-based anti-obesity interventions. Our analysis suggests a positive role for government intervention to reduce and prevent obesity. At the same time, we discuss criteria that can be used to draw lines between government, employer, and individual responsibility for health, and to derive principles that should guide and limit government interventions on obesity as health reform's various elements (e.g., exchanges, insurance market reforms) are implemented in the coming years. © 2011 American Society of Law, Medicine & Ethics, Inc.
Rare Genetic Forms of Obesity: Clinical Approach and Current Treatments in 2016
Huvenne, Hélène; Dubern, Béatrice; Clément, Karine; Poitou, Christine

Obesity results from a synergistic relationship between genes and the environment. The phenotypic expression of genetic factors involved in obesity is variable, allowing to distinguish several clinical pictures of obesity. Monogenic obesity is described as rare and severe early-onset obesity with abnormal feeding behavior and endocrine disorders. This is mainly due to autosomal recessive mutations in genes of the leptin-melanocortin pathway which plays a key role in the hypothalamic control of food intake. Melanocortin 4 receptor(MC4R)-linked obesity is characterized by the variable severity of obesity and no notable additional phenotypes. Mutations in the MC4R gene are involved in 2-3% of obese children and adults; the majority of these are heterozygous. Syndromic obesity is associated with mental retardation, dysmorphic features, and organ-specific developmental abnormalities. Additional genes participating in the development of hypothalamus and central nervous system have been regularly identified. But to date, not all involved genes have been identified so far. New diagnostic tools, such as whole-exome sequencing, will probably help to identify other genes. Managing these patients is challenging. Indeed, specific treatments are available only for specific types of monogenic obesity, such as leptin deficiency. Data on bariatric surgery are limited and controversial. New molecules acting on the leptin-melanocortin pathway are currently being developed. PMID:27241181
What Is Driving Obesity? A Review on the Connections Between Obesity and Motorized Transportation.
King, Douglas M; Jacobson, Sheldon H
2017-03-01
Traveling by automobile rather than walking or cycling can encourage obesity by eliminating physical activity. As national obesity rates in the USA have reached 37.9% in 2014, understanding the connections between obesity and transportation choices can help policymakers in the public health community propose effective obesity interventions at the national level. Following from foundational studies examining associations between the built environment and leisure walking, recent studies consider a diverse set of transportation choices regarding mode (e.g., automobile, walking, public transit) and purpose (e.g., commuting, leisure), along with studies on the effectiveness of several transportation-related interventions for obesity. The reviewed studies point toward potential interventions for obesity; there is emerging evidence that commuting by public transit may be one such intervention. Moreover, new data-gathering tools such as global positioning systems, geographic information systems, and accelerometers may alleviate statistical obstacles in conducting future studies.

Few data exist about the characteristics and management of enteric leaks after mini-gastric bypass (MGB). We aimed to describe the incidence, presentation, and surgical management of enteric leaks in patients who underwent laparoscopic MGB for morbid obesity. Private practice. An 8-year, 9-month retrospective chart review was performed on patients who had enteric leak requiring reoperation after MGB at a single institution. Thirty-five of 2321 patients were included. Ninety-seven percent had symptoms. Arterial hypertension and heavy smoking were predicting factors of leaks occurrence post-MGB (P<.01). Enteric leak was diagnosed by systematic upper gastrointestinal series in 4 pts (11.4%) and by computed tomography with oral water soluble contrast in 4 of 31 pts (13%). In the other 27 patients, diagnosis of the leak was made intraoperatively. Eleven patients (32%) had leak arising from the gastric stapler line (type 1), 4 (11%) from the gastrojejunal anastomosis (type 2), and 20 (57%) from undetermined origin. The most common presentation was intra-abdominal abscess in type 1 and leaks of undetermined origin and generalized peritonitis in type 2. One third of the patients who underwent reoperation developed well-drained chronic fistula into the irrigation-drainage system, with complete healing in all patients without any further procedure. The mean hospital stay was 19 days with no mortality reported. Enteric leak leading to intra-abdominal sepsis post-MGB is rare (1.5%) An operative aggressive management based on clinical symptoms is the treatment of choice allowing no postoperative leak-related mortality and complete healing.

Rates of obesity have increased significantly over the last three decades in the United States and globally. In addition to contributing to heart disease and diabetes, obesity is a major unrecognized risk factor for cancer. Obesity is associated with worsened prognosis after cancer diagnosis and also negatively affects the delivery of systemic therapy, contributes to morbidity of cancer treatment, and may raise the risk of second malignancies and comorbidities. Research shows that the time after a cancer diagnosis can serve as a teachable moment to motivate individuals to adopt risk-reducing behaviors. For this reason, the oncology care team--the providers with whom a patient has the closest relationships in the critical period after a cancer diagnosis--is in a unique position to help patients lose weight and make other healthy lifestyle changes. The American Society of Clinical Oncology is committed to reducing the impact of obesity on cancer and has established a multipronged initiative to accomplish this goal by 1) increasing education and awareness of the evidence linking obesity and cancer; 2) providing tools and resources to help oncology providers address obesity with their patients; 3) building and fostering a robust research agenda to better understand the pathophysiology of energy balance alterations, evaluate the impact of behavior change on cancer outcomes, and determine the best methods to help cancer survivors make effective and useful changes in lifestyle behaviors; and 4) advocating for policy and systems change to address societal factors contributing to obesity and improve access to weight management services for patients with cancer. © 2014 by American Society of Clinical Oncology.

Nonalcoholic steatohepatitis (NASH) is common in morbidly obese persons. Liver biopsy is diagnostic but technically challenging in such individuals. This study was undertaken to develop a clinically useful scoring system to predict the probability of NASH in morbidly obese persons, thus assisting in the decision to perform liver biopsy. Consecutive subjects undergoing bariatric surgery without evidence of other liver disease underwent intraoperative liver biopsy. The outcome was pathologic diagnosis of NASH. Predictors evaluated were demographic, clinical, and laboratory variables. A clinical scoring system was constructed by rounding the estimated regression coefficients for the independent predictors in a multivariate logistic model for the diagnosis of NASH. Of 200 subjects studied, 64 (32%) had NASH. Median body mass index was 48 kg/m(2) (interquartile range, 43-55). Multivariate analysis identified six predictive factors for NASH: the diagnosis of hypertension (odds ratio [OR], 2.4; 95% confidence interval [CI], 1-5.6), type 2 diabetes (OR, 2.6; 95% CI, 1.1-6.3), sleep apnea (OR, 4.0; 95% CI, 1.3-12.2), AST > 27 IU/L (OR, 2.9; 95% CI, 1.2-7.0), alanine aminotransferase (ALT) > 27 IU/L (OR, 3.3; 95% CI, 1.4-8.0), and non-Black race (OR, 8.4; 95% CI, 1.9-37.1). A NASH Clinical Scoring System for Morbid Obesity was derived to predict the probability of NASH in four categories (low, intermediate, high, and very high). The proposed clinical scoring can predict NASH in morbidly obese persons with sufficient accuracy to be considered for clinical use, identifying a very high-risk group in whom liver biopsy would be very likely to detect NASH, as well as a low-risk group in whom biopsy can be safely delayed or avoided.
Role of PUFAs, the precursors of endocannabinoids, in human obesity and type 2 diabetes.
Dain, Alejandro; Repossi, Gaston; Das, Undurti N; Eynard, Aldo Renato
2010-06-01
Polyunsaturated fatty acids (PUFAs) serve as precursors of the endocannabinoids (ECs) that are bioactive lipids molecules. Recent studies revealed that ECs participate in several physiological and pathological processes including obesity and type 2 diabetes mellitus. Here we review the experimental and clinical aspects of the role of endocannabinoids in obesity and type 2 diabetes mellitus and the modification of the endocannabinoids by exogenously administered PUFAs. Based on these evidences, we propose that the endocannabinoid system (ECS) can be modulated by exogenous manipulation of PUFAs that could help in the prevention and management of human diseases such as obesity, metabolic syndrome and type 2 diabetes mellitus.

Fink, Jennifer T; Smith, David R; Singh, Maharaj; Ihrke, Doug M; Cisler, Ron A
2016-04-01
The purpose of this research was to retrospectively examine whether demographic differences exist between those who participated in an employee wellness program and those who did not, and to identify the selection of employees' choice in weight management activities. A nonequivalent, 2-group retrospective design was used. This study involved employees at a large, not-for-profit integrated health system. Of the total organization employee pool (29,194), 19,771 (68%) employees volunteered to be weighed (mean body mass index [BMI]=28.9) as part of an employee wellness program. Weight management activities available included: (1) Self-directed 5% total body weight loss; (2) Healthy Solutions at home; (3) Weight Watchers group meetings; (4) Weight Watchers online; and (5) Employee Assistance Program (EAP)-directed healthy weight coaching. Measures were participation rate and available weight management activity participation rate among obese employees across demographic variables, including sex, age, race, job type, and job location. The analysis included chi-square tests for all categorical variables; odds ratios were calculated to examine factors predictive of participation. Of the total 19,771 employees weighed, 6375 (32%) employees were obese (defined as BMI ≥30); of those, 3094 (49%) participated in available weight management activities. Participation was higher among females, whites, those ages >50 years, and non-nursing staff. In conclusion, participation rate varied significantly based on demographic variables. Self-directed 5% weight loss was the most popular weight management activity selected. (Population Health Management 2016;19:132-135).
Obesity pharmacotherapy: What is next?
Colon-Gonzalez, Francheska; Kim, Gilbert W.; Lin, Jieru E.; Valentino, Michael A.; Waldman, Scott A.
2014-01-01
The increase in obesity in the Unites States and around the world in the last decade is overwhelming. The number of overweight adults in the world surpassed 1 billion in 2008. Health hazards associated with obesity are serious and include heart disease, sleep apnea, diabetes, and cancer. Although lifestyle modifications are the most straightforward way to control weight, a large portion of the population may not be able to rely on this modality alone. Thus, the development of anti-obesity therapeutics represents a major unmet medical need. Historically, anti-obesity pharmacotherapies have been unsafe and minimally efficacious. A better understanding of the biology of appetite and metabolism provides an opportunity to develop drugs that may offer safer and more effective alternatives for weight management. This review discusses drugs that are currently on the market and in development as anti-obesity therapeutics based on their target and mechanism of action. It should serve as a roadmap to establish expectations for the near future for anti-obesity drug development. PMID:23103610

Obesity is underdiagnosed, hampering system-based health promotion and research. Our objective was to develop and validate a claims-based risk model to identify obese persons using medical diagnosis and prescription records. We conducted a cross-sectional analysis of de-identified claims data from enrollees of 3 Blue Cross Blue Shield plans who completed a health risk assessment capturing height and weight. The final sample of 71,057 enrollees was randomly split into 2 subsamples for development and validation of the obesity risk model. Using the Johns Hopkins Adjusted Clinical Groups case-mix/predictive risk methodology, we categorized study members' diagnosis (ICD) codes. Logistic regression was used to determine which claims-based risk markers were associated with a body mass index (BMI) > or = 35 kg/m(2). The sensitivities of the scores > or =90(th) percentile to detect obesity were 26% to 33%, while the specificities were >90%. The areas under the receiver operator curve ranged from 0.67 to 0.73. In contrast, a diagnosis of obesity or an obesity medication alone had very poor sensitivity (10% and 1%, respectively); the obesity risk model identified an additional 22% of obese members. Varying the percentile cut-point from the 70(th) to the 99(th) percentile resulted in positive predictive values ranging from 15.5 to 59.2. An obesity risk score was highly specific for detecting a BMI > or = 35 kg/m(2) and substantially increased the detection of obese members beyond a provider-coded obesity diagnosis or medication claim. This model could be used for obesity care management and health promotion or for obesity-related research.

The severity of obstructive sleep apnea in children determines perioperative management and is an indication for postoperative polysomnography. The relationship between increasing weight and sleep apnea severity in children remains unclear. To compare demographic, clinical, and polysomnography parameters in normal-weight, overweight, obese, and morbidly obese children, as well as identify demographic factors that predict sleep apnea severity. Case series with chart review. Academic children's hospital. A retrospective chart review of 290 children aged 2 to 18 years who underwent polysomnography at an academic children's hospital was performed. Demographics, clinical findings, and polysomnographic parameters were recorded. Children were categorized as normal weight, overweight, obese, or morbidly obese. Differences were assessed using linear and logistical regression models. Significance was set at P < .05. Morbidly obese were older than normal-weight children (mean, 8.0 ± 0.5 years vs 5.8 ± 0.3 years; P < .001) and less likely to have a normal polysomnogram (16% vs 48%; P = .02). There were no differences in sex, ethnicity, birth status (term or preterm), or tonsil size between normal-weight, overweight, obese, and morbidly obese children. Sleep efficiency and percentage of time in rapid eye movement were decreased in morbidly obese compared with other children (P < .05). The apnea-hypopnea index was positively correlated with increasing body mass index z score only as a function of increasing age (P < .001). Obstructive sleep apnea severity is correlated with a combination of increasing age and weight but not with either variable independently. This study suggests that obese and morbidly obese older children are most likely to have severe obstructive sleep apnea. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

The Australian Capital Territory 'It's Your Move!' (ACT-IYM) was a three-year (2012-2014) systems intervention to prevent obesity among adolescents. The ACT-IYM project involved three intervention schools and three comparison schools and targeted secondary students aged 12-16 years. The intervention consisted of multiple initiatives at individual, community, and school policy level to support healthier nutrition and physical activity. Intervention school-specific objectives related to increasing active transport, increasing time spent physically active at school, and supporting mental wellbeing. Data were collected in 2012 and 2014 from 656 students. Anthropometric data were objectively measured and behavioural data self-reported. Proportions of overweight or obesity were similar over time within the intervention (24.5% baseline and 22.8% follow-up) and comparison groups (31.8% baseline and 30.6% follow-up). Within schools, two of three the intervention schools showed a significant decrease in the prevalence of overweight and obesity (p<0.05). There was some evidence of effectiveness of the systems approach to preventing obesity among adolescents. Implications for public health: The incorporation of systems thinking has been touted as the next stage in obesity prevention and public health more broadly. These findings demonstrate that the use of systems methods can be effective on a small scale. © 2017 The Authors.

Despite several clinical practice guidelines, there remains a considerable gap in prevention and management of obesity in primary care. To address the need for changing provider behaviour, a randomized controlled trial with convergent mixed method evaluation, the 5As Team (5AsT) study, was conducted. As part of the 5AsT intervention, the 5AsT tool kit was developed. This paper describes the development process and evaluation of these tools. Tools were co-developed by the multidisciplinary research team and the 5AsT, which included registered nurses/nurse practitioners (n = 15), mental health workers (n = 7) and registered dieticians (n = 7), who were previously randomized to the 5AsT intervention group at a primary care network in Edmonton, Alberta, Canada. The 5AsT tool development occurred through a practice/implementation-oriented, need-based, iterative process during learning collaborative sessions of the 5AsT intervention. Feedback during tool development was received through field notes and final provider evaluation was carried out through anonymous questionnaires. Twelve tools were co-developed with 5AsT. All tools were evaluated as either 'most useful' or 'moderately useful' in primary care practice by the 5AsT. Four key findings during 5AsT tool development were the need for: tools that were adaptive, tools to facilitate interdisciplinary practice, tools to help patients understand realistic expectations for weight loss and shared decision-making tools for goal setting and relapse prevention. The 5AsT tools are primary care tools which extend the utility of the 5As of obesity management framework in clinical practice. © 2015 The Authors.

Obesity and obesity-related conditions, such as type 2 diabetes, are a major issue for Veteran health. Veterans Health Administration (VA) researchers and health systems leaders have worked separately and together to provide more effective weight management programs for Veterans. Although randomized clinical trials are often considered the gold standard for establishing efficacy of interventions in controlled circumstances, pragmatic clinical trials (PCTs) provide agility for translation. VA researchers and health system leaders collaboratively designed a PCT to compare the Diabetes Prevention Program (VA-DPP) to usual care (MOVE!®) in promoting weight loss and glycemic control among overweight/obese Veterans with prediabetes. Together, they navigated the tensions that exist between quality improvement and research activities, facing challenges but reaping significant rewards. Early findings led to updated national guidance for delivering obesity treatment in VA. Partnered research and the use of PCTs can be powerful strategies for accelerating evidence-based findings into practice. Collaborative partnerships between researchers and health systems leaders can help enhance and sustain translation in real-world settings.
Development and Evaluation of an Obesity Ontology for Social Big Data Analysis.
Kim, Ae Ran; Park, Hyeoun-Ae; Song, Tae-Min
2017-07-01
The aim of this study was to develop and evaluate an obesity ontology as a framework for collecting and analyzing unstructured obesity-related social media posts. The obesity ontology was developed according to the 'Ontology Development 101'. The coverage rate of the developed ontology was examined by mapping concepts and terms of the ontology with concepts and terms extracted from obesity-related Twitter postings. The structure and representative ability of the ontology was evaluated by nurse experts. We applied the ontology to the density analysis of keywords related to obesity types and management strategies and to the sentiment analysis of obesity and diet using social big data. The developed obesity ontology was represented by 8 superclasses and 124 subordinate classes. The superclasses comprised 'risk factors,' 'types,' 'symptoms,' 'complications,' 'assessment,' 'diagnosis,' 'management strategies,' and 'settings.' The coverage rate of the ontology was 100% for the concepts and 87.8% for the terms. The evaluation scores for representative ability were higher than 4.0 out of 5.0 for all of the evaluation items. The density analysis of keywords revealed that the top-two posted types of obesity were abdomen and thigh, and the top-three posted management strategies were diet, exercise, and dietary supplements or drug therapy. Positive expressions of obesity-related postings has increased annually in the sentiment analysis. It was found that the developed obesity ontology was useful to identify the most frequently used terms on obesity and opinions and emotions toward obesity posted by the geneal population on social media.

GPR55 is a putative cannabinoid receptor, and l-α-lysophosphatidylinositol (LPI) is its only known endogenous ligand. We investigated 1) whether GPR55 is expressed in fat and liver; 2) the correlation of both GPR55 and LPI with several metabolic parameters; and 3) the actions of LPI on human adipocytes. We analyzed CB1, CB2, and GPR55 gene expression and circulating LPI levels in two independent cohorts of obese and lean subjects, with both normal or impaired glucose tolerance and type 2 diabetes. Ex vivo experiments were used to measure intracellular calcium and lipid accumulation. GPR55 levels were augmented in the adipose tissue of obese subjects and further so in obese patients with type 2 diabetes when compared with nonobese subjects. Visceral adipose tissue GPR55 correlated positively with weight, BMI, and percent fat mass, particularly in women. Hepatic GPR55 gene expression was similar in obese and type 2 diabetic subjects. Circulating LPI levels were increased in obese patients and correlated with fat percentage and BMI in women. LPI increased the expression of lipogenic genes in visceral adipose tissue explants and intracellular calcium in differentiated visceral adipocytes. These findings indicate that the LPI/GPR55 system is positively associated with obesity in humans. PMID:22179809

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.

Prenatal exposure to antibacterials may permanently dysregulate fetal metabolic patterns via epigenetic pathways or by altering maternal microbiota. We examined the association of prenatal exposure to systemic antibacterials with overweight and obesity in schoolchildren. We conducted a prevalence study among Danish schoolchildren aged 7-16 years using data from routine school anthropometric evaluations conducted during 2002-2013. Prenatal exposure to antibacterials was ascertained by using maternal prescription dispensations and infection-related hospital admissions during pregnancy. We defined overweight and obesity among the children using standard age- and sex-specific cutoffs. We computed sex-specific adjusted prevalence ratios (aPRs) of overweight and obesity associated with exposure to prenatal antibacterials, adjusting for maternal age at delivery, marital status, smoking in pregnancy and multiple gestation; we also stratified the analyses by birth weight. Among 9886 schoolchildren, 3280 (33%) had prenatal exposure to antibacterials. aPRs associated with the exposure were 1.26 (95% confidence interval (CI): 1.10-1.45) for overweight and 1.29 (95% CI: 1.03-1.62) for obesity. Among girls, aPRs were 1.16 (95% CI: 0.95-1.42) for overweight and 1.27 (95% CI: 0.89 to 1.82) for obesity. Among boys, aPRs were 1.37 (95% CI: 1.13-1.66) for overweight and 1.29 (95% CI: 0.96-1.73) for obesity. The aPR for overweight was higher among schoolchildren with birth weight <3500 g (aPR: 1.30, 95% CI: 1.05-1.61) than in schoolchildren with birth weight ⩾3500 g (aPR: 1.18, 95% CI: 0.95-1.46). Inversely, the association for obesity was higher among schoolchildren with birth weight ⩾3500 g (aPR: 1.35, 95% CI: 1.00-1.81) than among those who were <3500 g at birth (aPR: 1.16, 95% CI: 0.82-1.65). Prenatal exposure to systemic antibacterials is associated with an increased risk of overweight and obesity at school age, and this association varies by birth weight.

Obesity is an epidemic with important health repercussions in addition to high treatment-related costs. Between 2006 and 2007 the WHO developed new assessment tools, which aren't being globally used. In fact, there is no unified problem management across the hemisphere. To update obesity epidemiology, to promote application of WHO’s standards, to review new findings on physiopathology (i.e., fatty tissue as endocrine organ, intestinal microbiota), to update epidemiological information, and to provide management guidelines that can be integrated in clinical care. LAPSGHAN called up its members to collaborate in preparing this review article under the direction of an editor/coordinator, who selected the contents and literature with the best evidencetogether with the members. Each member prepared a separate document for each content. The chosen contents were later collated, unified, and edited. Results. This documents highlights the following: 1) Although extreme obesity is increasing in the US, overweight and obesity prevalence has stabilized, while in other countries it is alarmingly increasing; 2) New information regarding role of fatty tissue as endocrine organ and self-regulator of obesity; 3) The promising role of microbiota; and 4) Guidelines for children handling during consultation and follow-up. There is no widespread implementation of standards and guidelines from the World Health Organization (WHO). There is no agreement as to whether z-scores or percentiles should be used, especially regarding children under 2 due to their changing body complexion. The most accepted tool to assess overweight, obesity and severe obesity is the Body Mass Index (BMI). This document provides recommendations on how to approach clinical care with affected children.
Primary Care Interventions to Reduce Childhood Obesity in Latino Families.
Gonzalez, Giulliana
2016-01-01
Increasing rates of obesity in Latino children call for culturally sensitive primary care interventions. Despite recent efforts to address this growing disparity, little is known about cultural variables that influence obesity management programs in Latino children. A literature search was conducted using CINHAL, Scopus, PubMed, and PsycINFO to review the state of the science regarding primary care interventions to decrease obesity in Latino children. The author analyzed the effects of several cultural practices on obesity and made recommendations based on their clinical implications for weight reduction management programs. Obesity in Latino children is a multifactorial problem influenced by family behaviors, cultural perceptions of weight and health, traditional dietary norms, and socioeconomic status. Current practice lags behind national obesity management recommendations and is further hindered by a lack of consideration of the roles of key cultural differences in Latino families. It is imperative to recognize the importance of family preferences and culture when developing weight reduction programs so as to foster long-term behavior changes. More research assessing the efficacy of culturally competent interventions is necessary to guide national efforts to address this increasing disparity.

Obesity in women of reproductive age is increasing in prevelance worldwide. Obesity reduces fertility and increases time taken to conceive, and obesity-related comorbidities (such as type 2 diabetes and chronic hypertension) heighten the risk of adverse outcomes for mother and child if the woman becomes pregnant. Pregnant women who are obese are more likely to have early pregnancy loss, and have increased risk of congenital fetal malformations, delivery of large for gestational age infants, shoulder dystocia, spontaneous and medically indicated premature birth, and stillbirth. Late pregnancy complications include gestational diabetes and pre-eclampsia, both of which are associated with long-term morbidities post partum. Women with obesity can also experience difficulties during labour and delivery, and are more at risk of post-partum haemorrhage. Long-term health risks are associated with weight retention after delivery, and inherent complications for the next pregnancy. The wellbeing of the next generation is also compromised. All these health issues could be avoided by prevention of obesity among women of reproductive age, which should be viewed as a global public health priority. For women who are already obese, renewed efforts should be made towards improved management during pregnancy, especially of blood glucose, and increased attention to post-partum weight management. Effective interventions, tailored to ethnicity and culture, are needed at each of these stages to improve the health of women and their children in the context of the global obesity epidemic.

The study aim was to determine the utility of and satisfaction with a Centers for Disease Control and Prevention (CDC) Web-based employer tool, CDC's LEAN Works!, which provides evidence-based recommendations and promising practices for obesity prevention and control at worksites. This study examined employers' natural usage (i.e., without any study parameters on how, when, or how much to use the Web site and its resources) and impressions of the Web site. Employers of varying sizes, industry types, and levels of maturity in offering obesity management programs and from both private and public sectors were recruited to participate in the study. A convenience sample of 29 employers enrolled to participate. Participants were followed over a 12-month period. First impressions, bimonthly use of the Web site, and final assessments were collected using self-report surveys and individual interviews. Descriptive analyses were conducted. Almost all (96%) of participants reported a positive experience with the Web site, noting it provided a wealth of information. Most reported they planned to continue to use the Web site to develop (77%), implement (92%), and evaluate (85%) their obesity management programs. Aspects of the Web site that employers found valuable included a step-by-step implementation process, templates and toolkits, specific recommendations, and promising practices. CDC's LEAN Works! is a useful resource for employers wishing to develop and implement evidence-based workplace obesity prevention programs.
Do family meals affect childhood overweight or obesity?: nationwide survey 2008-2012.
Lee, H J; Lee, S Y; Park, E C
2016-06-01
The prevalence of childhood obesity is increasing worldwide and this trend is no exception for South Korea. A multidisciplinary approach is needed for the prevention and management of childhood obesity. To do so, among many other strategies, managing the family unit can be a very effective strategy. The purpose of this study was to identify the relationship between frequency of family meals and overweight/obesity in elementary students and to suggest the management and prevention strategies of childhood obesity. Data from a total of 2904 elementary students were analyzed from the 2008-2012 Korea National Health and Nutrition Examination Survey. Multiple logistic regression analysis was used to examine the association between overweight/obesity and family meals. Of the total 2904 elementary students, 573 (19.4%) were overweight or obese. The odds ratio of overweight or obese students who had family dinner only was 1.21 (95% CI: 0.89-1.64), that of those who had family breakfast only was 3.20 (95% CI: 1.70-6.02), and that of those who had neither family breakfast nor family dinner was 4.17 (95% CI: 1.98-8.78) compared with those who had both family breakfast and family dinner. The frequency of family meals was strongly an inverse association with childhood overweight or obesity. Therefore, we suggest that the intervention of childhood obesity should include family meals. © 2015 World Obesity.

A number of studies have associated obesity with altered gut microbiota, although results are discordant regarding compositional changes in the gut microbiota of obese animals. Herein we used a meta-analysis to obtain an unbiased evaluation of structural and functional changes of the gut microbiota in diet-induced obese rodents. The raw sequencing data of nine studies generated from high-fat diet (HFD)-induced obese rodent models were processed with QIIME to obtain gut microbiota compositions. Biological functions were predicted and annotated with KEGG pathways with PICRUSt. No significant difference was observed for alpha diversity and Bacteroidetes-to-Firmicutes ratio between obese and lean rodents. Bacteroidia, Clostridia, Bacilli, and Erysipelotrichi were dominant classes, but gut microbiota compositions varied among studies. Meta-analysis of the nine microbiome data sets identified 15 differential taxa and 57 differential pathways between obese and lean rodents. In obese rodents, increased abundance was observed for Dorea, Oscillospira, and Ruminococcus, known for fermenting polysaccharide into short chain fatty acids (SCFAs). Decreased Turicibacter and increased Lactococcus are consistent with elevated inflammation in the obese status. Differential functional pathways of the gut microbiome in obese rodents included enriched pyruvate metabolism, butanoate metabolism, propanoate metabolism, pentose phosphate pathway, fatty acid biosynthesis, and glycerolipid metabolism pathways. These pathways converge in the function of carbohydrate metabolism, SCFA metabolism, and biosynthesis of lipid. HFD-induced obesity results in structural and functional dysbiosis of gut microbiota. The altered gut microbiome may contribute to obesity development by promoting insulin resistance and systemic inflammation.

Introduction We present a case on conservative management of salvaging the mesh in an immunocompromised morbidly obese patient, who developed a synergistic gangrene infection following a primary open mesh repair of an incisional hernia. Presentation of case Our patient presented with a surgical wound infection, comorbidities were Chronic Lymphoblastic Leukemia (CLL), Body Mass Index (BMI) of 50, hypertension and diet controlled type-2 diabetes. In surgery, wide necrotic wound debridement, early and repetitive wound drainages with the use of a large pore polypropylene mesh and a detailed surgical follow up was required. High dose intravenous broad-spectrum antibiotic treatment and Negative Pressure Wound Therapy (NPWT) was administrated in combination with adopting a multidisciplinary approach was key to our success. Discussion Stoppa Re et al. complied a series of 360 ventral hernia mesh repairs reporting an infection rate of 12% that were managed conservatively. However, our selective case is unique within current literature, being the first to illustrate mesh salvage in a morbid obese patient with CLL. Recent modifications in mesh morphology, such as lower density, wide pores, and lighter weight has led to considerable improvements regarding infection avoidance. Conclusion This case has demonstrated how a planned multidisciplinary action can produce prosperous results in a severely obese immunocompromised patient with an SSI, following an incisional hernia repair.

Obesity and chronic disease: always offender or often just accomplice?
Egger, Garry; Dixon, John
2009-10-01
Over a decade ago, the finding of a form of low-grade systemic inflammation ('metaflammation') associated with obesity, insulin resistance and chronic disease proffered a causal explanation for the latter. However, recent work has shown that metaflammation is also associated with several modern lifestyle-related and environmental inducers, with or without obesity. Here, we present accumulating data to show a link between metaflammation and a number of non-microbial environmental and lifestyle stimulants, both with and without obesity. This implies that obesity may often be an accomplice to, as much as an offender in, major metabolic disease. The real (albeit distal) cause of such a disease appears to lie in aspects of the modern techno-industrial environment driving unhealthy lifestyle behaviours. If true, this suggests that while individual weight loss may be a component of chronic disease management, it may be neither 'necessary' nor 'sufficient' to reduce the problem at a population level. Greater multidisciplinary and policy input is needed to modify the economic and political drivers of the modern, obesogenic environment.
Innate Immune Activation in Obesity
Lumeng, Carey N.
2014-01-01
The innate immune system is a prewired set of cellular and humoral components that has developed to sense perturbations in normal physiology and trigger responses to restore the system back to baseline. It is now understood that many of these components can also sense the physiologic changes that occur with obesity and be activated. While the exact reasons for this chronic immune response to obesity are unclear, there is strong evidence to suggest that innate inflammatory systems link obesity and disease. Based on this, anti-inflammatory therapies for diseases like type 2 diabetes and metabolic syndrome may form the core of future treatment plans. This review will highlight the components involved in the innate immune response and discuss the evidence that they contribute to the pathogenesis of obesity-associated diseases. PMID:23068074

Background Obesity is a major global epidemic and a burden to society and health systems. It is well known risk factor for a number of chronic medical conditions with high morbidity and mortality. This study aimed to provide an estimate of the direct costs associated to outpatient and inpatient care of overweight and obesity related diseases in the perspective of the Brazilian Health System (SUS). Methods Population attributable risk (PAR) was calculated for selected diseases related to overweight and obesity and with the following parameters: Relative risk (RR) ≥ 1.20 or RR ≥1.10 and < 1.20, but important problem of public health due its high prevalence. After a broad search in the literature, two meta-analysis were selected to provide RR for PAR calculation. The prevalence rates of overweight and obesity in Brazilians with ≥18 years were obtained from large national survey. The national health database (DATASUS) was used to estimate the annual cost of the Brazilian Unified Health System (SUS) with the diseases included in the analysis. The extracted values were stratified by sex, type of service (inpatient or outpatient care) and year. Data were collected from 2008 to 2010 and the results reflect the average of 3 years. Brazilian costs were converted into US dollars during the analysis using a purchasing power parity basis (2010). Results The estimated total costs in one year with all diseases related to overweight and obesity are US$ 2,1 billion; US$ 1,4 billion (68.4% of total costs) due to hospitalizations and US$ 679 million due to ambulatory procedures. Approximately 10% of these cost is attributable to overweight and obesity. Conclusion The results confirm that overweight and obesity carry a great economic burden for Brazilian health system and for the society. The knowledge of these costs will be useful for future economic analysis of preventive and treatment interventions. PMID:22713624
Dysfunction of autonomic nervous system in childhood obesity: a cross-sectional study.

To assess the distribution of autonomic nervous system (ANS) dysfunction in overweight and obese children. Parasympathetic and sympathetic ANS function was assessed in children and adolescents with no evidence of impaired glucose metabolism by analysis of heart rate variability (low frequency power ln(LF), high frequency power, ln(HF); ln(LF/HF) ratio, ratio of longest RR interval during expiration to shortest interval during inspiration (E/I ratio), root mean square of successive differences (RMSSD); sympathetic skin response (SSR); and quantitative pupillography (pupil diameter in darkness, light reflex amplitude, latency, constriction velocity, re-dilation velocity). The relationship of each ANS variable to the standard deviation score of body mass index (BMI-SDS) was assessed in a linear model considering age, gender and pubertal stage as co-variates and employing an F-statistic to compare the fit of nested models. Group comparisons between normal weight and obese children as well as an analysis of dependence on insulin resistance (as indexed by the Homeostasis Model Assessment of Insulin Resistance, HOMA-IR) were performed for parameters shown to correlate with BMI-SDS. Statistical significance was set at 5%. Measurements were performed in 149 individuals (mean age 12.0 y; 90 obese 45 boys; 59 normal weight, 34 boys). E/I ratio (p = 0.003), ln(HF) (p = 0.03), pupil diameter in darkness (p = 0.01) were negatively correlated with BMI-SDS, whereas ln(LF/HF) was positively correlated (p = 0.05). Early re-dilation velocity was in trend negatively correlated to BMI-SDS (p = 0.08). None of the parameters that depended significantly on BMI-SDS was found to be significantly correlated with HOMA-IR. These findings demonstrate extended ANS dysfunction in obese children and adolescents, affecting several organ systems. Both parasympathetic activity and sympathetic activity are reduced. The conspicuous pattern of ANS dysfunction raises the possibility that obesity may give

To review the evidence and provide recommendations for the counselling and management of obese parturients. Outcomes evaluated include the impact of maternal obesity on the provision of antenatal and intrapartum care, maternal morbidity and mortality, and perinatal morbidity and mortality. Literature was retrieved through searches of Statistics Canada, Medline, and The Cochrane Library on the impact of obesity in pregnancy on antepartum and intrapartum care, maternal morbidity and mortality, obstetrical anaesthesia, and perinatal morbidity and mortality. Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to April 2009. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The evidence obtained was reviewed and evaluated by the Maternal Fetal Medicine and Clinical Practice Obstetric Committees of the SOGC under the leadership of the principal authors, and recommendations were made according to guidelines developed by the Canadian Task Force on Preventive Health Care. Implementation of the recommendations in this guideline should increase recognition of the issues clinicians need to be aware of when managing obese women in pregnancy, improve communication and consultation amongst the obstetrical care team, and encourage federal and provincial agencies to educate Canadians about the values of entering pregnancy with as healthy a weight as possible. 1. Periodic health examinations and other appointments for gynaecologic care prior to pregnancy offer ideal opportunities to raise the issue of weight loss before conception. Women should be
Development and Evaluation of an Obesity Ontology for Social Big Data Analysis
Kim, Ae Ran; Song, Tae-Min
2017-01-01
Objectives The aim of this study was to develop and evaluate an obesity ontology as a framework for collecting and analyzing unstructured obesity-related social media posts. Methods The obesity ontology was developed according to the ‘Ontology Development 101’. The coverage rate of the developed ontology was examined by mapping concepts and terms of the ontology with concepts and terms extracted from obesity-related Twitter postings. The structure and representative ability of the ontology was evaluated by nurse experts. We applied the ontology to the density analysis of keywords related to obesity types and management strategies and to the sentiment analysis of obesity and diet using social big data. Results The developed obesity ontology was represented by 8 superclasses and 124 subordinate classes. The superclasses comprised ‘risk factors,’ ‘types,’ ‘symptoms,’ ‘complications,’ ‘assessment,’ ‘diagnosis,’ ‘management strategies,’ and ‘settings.’ The coverage rate of the ontology was 100% for the concepts and 87.8% for the terms. The evaluation scores for representative ability were higher than 4.0 out of 5.0 for all of the evaluation items. The density analysis of keywords revealed that the top-two posted types of obesity were abdomen and thigh, and the top-three posted management strategies were diet, exercise, and dietary supplements or drug therapy. Positive expressions of obesity-related postings has increased annually in the sentiment analysis. Conclusions It was found that the developed obesity ontology was useful to identify the most frequently used terms on obesity and opinions and emotions toward obesity posted by the geneal population on social media.

Objective Adult obesity is recognized as a chronic disease. According to principles of chronic disease management, healthcare professionals should work collaboratively with patients to determine appropriate therapeutic strategies that address overweight and obesity, specifically considering a patient’s disease status in addition to their individual needs, preferences, and attitudes regarding treatment. A central role and responsibility of healthcare professionals in this process is to inform and educate patients about their treatment options. Although current recommendations for the management of adult obesity provide general guidance regarding safe and proper implementation of lifestyle, pharmacological, and surgical interventions, healthcare professionals need awareness of specific evidence-based information that supports individualized clinical application of these therapies. More specifically, healthcare professionals should be up-to-date on approaches that promote successful lifestyle management and be knowledgeable about newer weight loss pharmacotherapies, so they can offer patients with obesity a wide range of options to personalize their treatment. Accordingly, this educational activity has been developed to provide participants with the latest information on treatment recommendations and therapeutic advances in lifestyle intervention and pharmacotherapy for adult obesity management. Design and Methods This supplement is based on the content presented at a live CME symposium held in conjunction with ObesityWeek 2014. Results This supplement provides an expert summary of current treatment recommendations and recent advances in nonsurgical therapies for the management of adult obesity. Patient and provider perspectives on obesity management are highlighted in embedded video clips available via QR codes, and new evidence will be applied using clinically relevant case studies. Conclusions This supplement provides a topical update of obesity management

Background Severe obesity in adolescents has deleterious physical and psychological complications necessitating frequent multi-disciplinary clinic visits. Greater treatment engagement has been equated with weight-loss. However, traditional medical weight-loss programs for adolescents have high attrition rates. Social media is widely used by adolescents and may enhance medical weight management engagement and success. Objective The first objective was to examine the acceptability and feasibility of using a private social media group as an adjunct to medical weight management in youth ages 14 to 20 years with severe obesity [body mass index (BMI) ≥ 35 kg/m2]. The second objective was to pilot test the use of social media to improve treatment engagement and decrease attrition rates. Methods In this single arm, 12 week pre-post study, participants attended individual clinic visits and participated in a moderated private social media group that received nutrition, exercise, and behavior change social media communications or “posts” 3 to 4 times/week. Youth commented and/or liked posts from the moderator and each other. Social media engagement was measured with the number of likes and comments on social media. Clinic attrition was compared, measuring clinic visit attendance 12 weeks prior, during, and after the intervention with mixed linear regression models. Correlations of social media engagement with changes from baseline for BMI, BMI-z score, and psychosocial measures were fit. Results All 13 enrolled youth completed the study and reported that the group was enjoyable, helpful, reinforced their weight management program, and would recommend using social media to support other youth. The pilot trial was acceptable and feasible. Youth mean weekly engagement (likes + comments) in social media was greater than once a day (8.6 ±3.6). Compared to 12 weeks prior to the intervention, there was no significant decrease in clinic visit attendance at the end of the

Achondroplasia is the most common form among the different types of osteochondrodysplasia that cause dwarfism. Dwarves develop obesity quite frequently and surgical treatment has shown greater efficacy, both for effective weight loss and long term maintenance. The objective of this report was to present the case of bariatric surgery with Y-en-Roux gastric bypass in an achondroplastic dwarf with morbid obesity. The different difficulties in the anesthetic management of this patient and the way they were dealt with were discussed in order to decrease intraoperative morbidity and mortality. This is a 29 years old female dwarf with achondroplasia and morbid obesity since childhood. She was 123 cm tall and weighed 144 kg at the time of admission to the Bariatric Surgery service. With a body mass index (BMI) of 95.18 kg.m2, she had several associated diseases especially of the respiratory system and osteoarticular system. After a long follow-up with diet, exercises, and psychological support, her clinical condition improved and she was referred for surgery: Y-en-Roux gastroplasty using the technique of Capella-Fobi. Intubation of the awake patient under direct laryngoscopy was difficult and a bronchofibroscope had to be used. Surgery was uneventful and the patient was maintained under total intravenous anesthesia with continuous infusion of remifentanil and propofol. She was extubated at the end of the surgery still in the operating room. The simultaneous comorbidities of achondroplasia and morbid obesity can hinder the anesthetic management, especially regarding the airways. A thorough pre-anesthetic evaluation is necessary to anticipate the conducts and minimize risks, therefore optimizing the evolution of anesthesia.
Gastrointestinal Morbidity in Obesity
Acosta, Andres; Camilleri, Michael
2014-01-01
Obesity is a complex disease that results from increased energy intake and decreased energy expenditure. The gastrointestinal system plays a key role in the pathogenesis of obesity and facilitates caloric imbalance. Changes in gastrointestinal hormones and the inhibition of mechanisms that curtail caloric intake result in weight gain. It is not clear if the gastrointestinal role in obesity is a cause or an effect of this disease. Obesity is often associated with type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVD). Obesity is also associated with gastrointestinal disorders, which are more frequent and present earlier than T2DM and CVD. Diseases such as gastro-esophageal reflux disease, cholelithiasis or non-alcoholic steatohepatitis are directly related to body weight and abdominal adiposity. Our objective is to assess the role of each gastrointestinal organ in obesity and the gastrointestinal morbidity resulting in those organs from effects of obesity. PMID:24602085
The Role of Aldosterone in Obesity-Related Hypertension
Kawarazaki, Wakako
2016-01-01
Obese subjects often have hypertension and related cardiovascular and renal diseases, and this has become a serious worldwide health problem. In obese subjects, impaired renal-pressure natriuresis causes sodium retention, leading to the development of salt-sensitive hypertension. Physical compression of the kidneys by visceral fat and activation of the sympathetic nervous system, renin–angiotensin systems (RAS), and aldosterone/mineralocorticoid receptor (MR) system are involved in this mechanism. Obese subjects often exhibit hyperaldosteronism, with increased salt sensitivity of blood pressure (BP). Adipose tissue excretes aldosterone-releasing factors, thereby stimulating aldosterone secretion independently of the systemic RAS, and aldosterone/MR activation plays a key role in the development of hypertension and organ damage in obesity. In obese subjects, both salt sensitivity of BP, enhanced by obesity-related metabolic disorders including aldosterone excess, and increased dietary sodium intake are closely related to the incidence of hypertension. Some salt sensitivity-related gene variants affect the risk of obesity, and together with salt intake, its combination is possibly associated with the development of hypertension in obese subjects. With high salt levels common in modern diets, salt restriction and weight control are undoubtedly important. However, not only MR blockade but also new diagnostic modalities and therapies targeting and modifying genes that are related to salt sensitivity, obesity, or RAS regulation are expected to prevent obesity and obesity-related hypertension.

The prevalence of obesity among children and adolescents is on the rise. The majority of overweight or obese children are treated by primary health care providers including paediatricians, family practitioners, dieticians, nurses, and school health services - and not by specialists. The majority of obese children have no underlying medical disorder causing their obesity yet a significant proportion might suffer from obesity-related co-morbidities. This text is aimed at providing simple and practical tools for the identification and management of children with or at risk of overweight and obesity in the primary care setting. The tips and tools provided are based on data from the recent body of work that has been published in this field, official statements of several scientific societies along with expert opinion provided by the members of the Childhood Obesity Task Force (COTF) of the European Association for the Study of Obesity (EASO). We have attempted to use an evidence-based approach while allowing flexibility for the practicing clinician in domains where evidence is currently lacking and ensuring that treating the obese child involves the entire family as well.

A growing body of literature suggests that obesity has a significant impact on asthma risk, phenotype, and prognosis. Epidemiological studies have clearly demonstrated that asthma is more likely to occur in obese patients, and health status is impaired in obese individuals with asthma, with obese asthmatics experiencing more symptoms, worse quality of life, increased healthcare use, and increased asthma severity. However, obesity has well-described effects on lung function and mechanics that can lead to symptoms of dyspnea without causing the pathophysiologic changes of asthma. Adding to the challenges of evaluating this association, some studies have failed to demonstrate a robust relationship between obesity and traditional biomarkers of airway inflammation in adult asthmatics, leading to the conclusion that obesity does not necessarily worsen airway inflammation in asthma. In this regard, emerging data suggest that nonatopic mechanisms may be relevant in obese asthmatics, and that these mechanisms may have a direct impact on the response of obese asthmatics to asthma therapies, most notably inhaled glucocorticoids. This article will review selected aspects of the contributions of obesity-related airway and systemic inflammation to asthma, with a focus on the impact of obesity as a modifier of risk, prognosis, and therapeutic response in asthma. © 2014 New York Academy of Sciences.

A comprehensive policy approach is needed to control the growing obesity epidemic. This paper proposes the Obesity Policy Action (OPA) framework, modified from the World Health Organization framework for the implementation of the Global Strategy on Diet, Physical Activity and Health, to provide specific guidance for governments to systematically identify areas for obesity policy action. The proposed framework incorporates three different public health approaches to addressing obesity: (i) 'upstream' policies influence either the broad social and economic conditions of society (e.g. taxation, education, social security) or the food and physical activity environments to make healthy eating and physical activity choices easier; (ii) 'midstream' policies are aimed at directly influencing population behaviours; and (iii) 'downstream' policies support health services and clinical interventions. A set of grids for analysing potential policies to support obesity prevention and management is presented. The general pattern that emerges from populating the analysis grids as they relate to the Australian context is that all sectors and levels of government, non-governmental organizations and private businesses have multiple opportunities to contribute to reducing obesity. The proposed framework and analysis grids provide a comprehensive approach to mapping the policy environment related to obesity, and a tool for identifying policy gaps, barriers and opportunities.

Background Although the United Kingdom’s (UK’s) General Medical Council (GMC) recommends that graduating medical students are competent to discuss obesity and behaviour change with patients, it is difficult to integrate this education into existing curricula, and clinicians report being unprepared to support patients needing obesity management in practice. We therefore aimed to identify factors influencing the integration of obesity management education within medical schools. Methods Twenty-seven UK and Irish medical school educators participated in semi-structured interviews. Grounded theory principles informed data collection and analysis. Themes emerging directly from the dataset illustrated key challenges for educators and informed several suggested solutions. Results Factors influencing obesity management education included: 1) Diverse and opportunistic learning and teaching, 2) Variable support for including obesity education within undergraduate medical programmes, and 3) Student engagement in obesity management education. Findings suggest several practical solutions to identified challenges including clarifying recommended educational agendas; improving access to content-specific guidelines; and implementing student engagement strategies. Conclusions Students’ educational experiences differ due to diverse interpretations of GMC guidelines, educators’ perceptions of available support for, and student interest in obesity management education. Findings inform the development of potential solutions to these challenges which may be tested further empirically. PMID:23578257

Chronic inflammation has been proposed to contribute to the pathogenesis of diet-induced obesity. However, scarce therapeutic options are available to treat obesity and the associated immunometabolic complications. Glucocorticoids are routinely employed for the management of inflammatory diseases, but their pleiotropic nature leads to detrimental metabolic side effects. We developed a glucagon-like peptide-1 (GLP-1)-dexamethasone co-agonist in which GLP-1 selectively delivers dexamethasone to GLP-1 receptor-expressing cells. GLP-1-dexamethasone lowers body weight up to 25% in obese mice by targeting the hypothalamic control of feeding and by increasing energy expenditure. This strategy reverses hypothalamic and systemic inflammation while improving glucose tolerance and insulin sensitivity. The selective preference for GLP-1 receptor bypasses deleterious effects of dexamethasone on glucose handling, bone integrity, and hypothalamus-pituitary-adrenal axis activity. Thus, GLP-1-directed glucocorticoid pharmacology represents a safe and efficacious therapy option for diet-induced immunometabolic derangements and the resulting obesity.

The major aim of this study was to investigate whether the motivational salience of food cues (as reflected by their attention-grabbing properties) differs between obese and normal-weight subjects in a manner consistent with altered reward system function in obesity. A total of 18 obese and 18 normal-weight, otherwise healthy, adult women between the ages of 18 and 35 participated in an eye-tracking paradigm in combination with a visual probe task. Eye movements and reaction time to food and non-food images were recorded during both fasted and fed conditions in a counterbalanced design. Eating behavior and hunger level were assessed by self-report measures. Obese individuals had higher scores than normal-weight individuals on self-report measures of responsiveness to external food cues and vulnerability to disruptions in control of eating behavior. Both obese and normal-weight individuals demonstrated increased gaze duration for food compared to non-food images in the fasted condition. In the fed condition, however, despite reduced hunger in both groups, obese individuals maintained the increased attention to food images, whereas normal-weight individuals had similar gaze duration for food and non-food images. Additionally, obese individuals had preferential orienting toward food images at the onset of each image. Obese and normal-weight individuals did not differ in reaction time measures in the fasted or fed condition. Food cue incentive salience is elevated equally in normal-weight and obese individuals during fasting. Obese individuals retain incentive salience for food cues despite feeding and decreased self-report of hunger. Sensitization to food cues in the environment and their dysregulation in obese individuals may play a role in the development and/or maintenance of obesity.

Venous thromboembolism (VTE) remains among the leading causes of maternal mortality in the developed world, presenting variably as deep vein thrombosis (DVT), pulmonary embolism (PE) or cerebral vein thrombosis (CVT), among others. Obesity in particular has been recognized as the principal contributing factor to the risk of VTE in pregnancy and with the global increase in the rates of obesity affecting reproductive age women, heightened awareness of the risk and consequences of VTE in this population are vital. Thus, prophylaxis, diagnosis and treatment of VTE in the obese gravida are discussed.

Overweight and obesity are highly prevalent conditions worldwide, linked to an increased risk for death, disability and disease due to metabolic and biochemical abnormalities affecting the biological human system throughout different domains. Biomarkers, defined as indicators of biological processes in health and disease, relevant for body mass excess management have been identified according to different criteria, including anthropometric and molecular indexes, as well as physiological and behavioural aspects. Analysing these different biomarkers, we identified their potential role in diagnosis, prognosis and treatment. Epigenetic biomarkers, cellular mediators of inflammation and factors related to microbiota-host interactions may be considered to have a theranostic value. Though, the molecular processes responsible for the biological phenomenology detected by the other analysed markers, is not clear yet. Nevertheless, these biomarkers possess valuable diagnostic and prognostic power. A new frontier for theranostic biomarkers can be foreseen in the exploitation of parameters defining behaviours and lifestyles linked to the risk of obesity, capable to describe the effects of interventions for obesity prevention and treatment which include also behaviour change strategies.

Contributing factors to obesity have been identified, yet prevention and treatment efforts have had limited long-term success. It has recently been suggested that some individuals may experience an addictive-like response to certain foods, such as losing control over consumption and continued consumption despite negative consequences. In support, shared biological and behavioral features seem to exist between "food addiction" and traditional substance-use disorders. "Food addiction" may be another important contributor to obesity. The current chapter reviews existing literature regarding neural systems implicated similarly in obesity and addiction, discusses unique considerations for addictive-like eating, and proposes directions for future research regarding "food addiction" as an emerging construct for addiction medicine. © 2016 Elsevier B.V.

Childhood obesity is one of the greatest health challenges of the 21st century. The EASO COTF is convinced that classifying obesity as a chronic disease in children and adolescents is a crucial step for increasing individual and societal awareness, and for improving early diagnosis and intervention. Such a classification will enhance the development of novel preventive and treatment approaches, health care policies and systems, and the education of healthcare workers. The management of obesity prior to the appearance of co-morbidities may prevent their escalation into significant medical and psychosocial problems, and reduce their economic and societal impact. Childhood is a unique window of opportunity to influence lifetime effects on health, quality of life, prevention of non-communicable chronic diseases and disabilities. The Convention on the Rights of the Child by UNICEF states that parties shall strive to ensure that no child is deprived of his or her right of access to health care services. The EASO COTF is aiming to address these issues via educational activities for health care workers, identification of research agendas, and the promotion of collaborations among clinicians, researchers, health institutions, organizations and states across Europe.

Beyond Obesity and Lifestyle: A Review of 21st Century Chronic Disease Determinants
Dixon, John
2014-01-01
The obesity epidemic and associated chronic diseases are often attributed to modern lifestyles. The term “lifestyle” however, ignores broader social, economic, and environmental determinants while inadvertently “blaming the victim.” Seen more eclectically, lifestyle encompasses distal, medial, and proximal determinants. Hence any analysis of causality should include all these levels. The term “anthropogens,” or “…man-made environments, their by-products and/or lifestyles encouraged by these, some of which may be detrimental to human health” provides a monocausal focus for chronic diseases similar to that which the germ theory afforded infectious diseases. Anthropogens have in common an ability to induce a form of chronic, low-level systemic inflammation (“metaflammation”). A review of anthropogens, based on inducers with a metaflammatory association, is conducted here, together with the evidence for each in connection with a number of chronic diseases. This suggests a broader view of lifestyle and a focus on determinants, rather than obesity and lifestyle per se as the specific causes of modern chronic disease. Under such an analysis, obesity is seen more as “a canary in a mineshaft” signaling problems in the broader environment, suggesting that population obesity management should be focused more upstream if chronic diseases are to be better managed.

Total laparoscopic hysterectomy (TLH) in obese patients is challenging. We sought to evaluate whether total laparoscopic hysterectomies using the da Vinci robotic system in obese patients, in comparison with non-obese patients, is a reasonable surgical approach. One-hundred consecutive robot-assisted TLHs were performed over a 17-month period. Obesity was not a contraindication to robotic surgery, assuming adequate respiratory function to tolerate Trendelenburg position and, for cancer cases, a small enough uterus to allow vaginal extraction without morcellation. Data were prospectively collected on patient characteristics, total operative time, hysterectomy time, estimated blood loss, length of stay, and complications. Outcomes with non-obese and obese women were compared. The median age, weight, and BMI of the 100 patients who underwent robot-assisted TLH was 57.6 years (30.0-90.6), 82.1 kg (51.9-159.6), and 30.2 kg/m(2) (19.3-60.2), respectively. Fifty (50%) patients were obese (BMI ≥ 30); 22 patients were morbidly obese (BMI ≥ 40). There was no increase in complications (p = 0.56) or blood loss (p = 0.44) with increasing BMI. While increased BMI was associated with longer operative times (p = 0.05), median time increased by only 36 min when comparing non-obese and morbidly obese patients. Median length of stay was one day for all weight categories (p = 0.42). Robot-assisted TLH is feasible and can be safely performed in obese patients. More data are needed to compare robot-assisted TLH with other hysterectomy techniques in obese patients. Nonetheless, our results are encouraging. Robot-assisted total laparoscopic hysterectomy may be the preferred technique for appropriately selected obese patients.
New medications for treatment of obesity: metabolic and cardiovascular effects.
Pucci, Andrea; Finer, Nicholas
2015-02-01
The management of obesity remains a major challenge. Dietary therapy often fails, whereas bariatric surgery, although successful, is demanding and applicable to a limited number of patients. Drug therapy has had many setbacks over the past 20 years because of serious adverse effects; however, several new drugs for the treatment of obesity are either licensed in some parts of the world, submitted for registration, or completing phase III trials. These include combinations (at low dose) of existing drugs, e.g., bupropion + naltrexone (Contrave), phentermine + topiramate (Qsymia), higher doses of existing drugs licensed for other indications (liraglutide, 3 mg), and new entities (lorcaserin). We discuss the challenges and opportunities for obesity pharmacotherapy and review in detail the efficacy of the new drugs regarding weight loss and both desirable and potential undesirable cardiovascular (CV) and metabolic risk factors. Substantial barriers remain, even if the drugs are approved, in successfully integrating these agents into weight management practice, largely related to cost, patient acceptability, and clinician willingness to be engaged in obesity treatment. Although hard clinical outcome benefit (at least for CV outcomes) has yet to be established, obesity pharmacotherapy may soon address many of the challenges in the clinical management of obesity, although newer and better drug combinations and more evidence of benefit from appropriately designed outcome trials is needed.

Osteosarcopenic obesity in women: impact, prevalence, and management challenges
JafariNasabian, Pegah; Inglis, Julia E; Kelly, Owen J; Ilich, Jasminka Z
2017-01-01
Osteosarcopenic obesity syndrome (OSO) has recently been identified as a condition encompassing osteopenia/osteoporosis, sarcopenia and obesity. OSO is especially deleterious in older adults (even if they are not obese by conventional measures), due to age-related redistribution of fat and its infiltration into bone and muscle. Osteoporosis and bone fractures in elderly increase the risk of sarcopenia, which, through decreased mobility, increases the risk of more falls and fractures, creating a vicious cycle. Obesity plays a dual role: to a certain extent, it promotes bone and muscle gains through mechanical loading; in contrast, increased adiposity is also a source of pro-inflammatory cytokines and other endocrine factors that impair bone and muscle. As the elderly population increases, changes in lifestyle to delay the onset of OSO, or prevent OSO, are warranted. Among these changes, dietary patterns and physical activity modifications are the first ones to be implemented. The typical Western diet (and lifestyle) promotes several chronic diseases including OSO, by facilitating a pro-inflammatory state, largely via the imbalance in omega-6/omega-3 fatty acid ratio and low-fiber and high-processed food consumption. Nutritional modifications to prevent and/or alleviate the OSO syndrome include adequate intake of protein, calcium, magnesium and vitamin D and increasing consumptions of foods containing omega-3 polyunsaturated fatty acids and fiber. Certain types of physical activity, often decreased in overweight/obese women and in elderly, might preserve bone and muscle, as well as help in reducing body fat accrual and fat infiltration. Habitual daily activities and some alternative modes of exercise may be more appropriate for older adults and play a crucial role in preventing bone and muscle loss and maintaining optimal weight. In conclusion, older adults who suffer from OSO syndrome may benefit from combined efforts to improve diet and physical activity, and such

School entry provides an opportune moment for health professionals to intervene with children who are overweight, yet identification and management of childhood obesity presents challenges in practice. This multi-method qualitative study explored the experiences of 26 school health professionals in addressing childhood obesity at school entry. Methods included semi-structured interviews with service managers (n = 3); focus groups with school nurses (n = 12) and child health practitioners (n = 6); and open-ended questionnaires with school nurses (n = 4) and child health practitioners (n = 1) who were unable to attend the focus groups. A thematic analysis revealed agreement between service managers, school nurses and child health practitioners. Whilst it was felt school health professionals have an important role to play in managing childhood obesity, efforts to address child weight were limited by a lack of capacity, lack of clear protocols, challenges of engaging parents and insufficient training in childhood obesity and related lifestyle issues. School health policymakers need to recognize childhood obesity as a serious public health issue, allocate appropriate resources to nurse training and development and ensure clear pathways are established to ensure consistency of care. © The Author(s) 2015.

The prevalence of obesity is associated with many health-related problems. Currently, more than 300 million people are considered to be obese. According to the World Health Organization (WHO), by 2030, 87 and 439 million people will be affected in India and the world, respectively. Today, herbal medicines are gaining interest in the treatment of obesity and diabetes, because of their minimal side effects. Gymnemic acid - an active component isolated from Gymnema sylvestre - has anti-obesity and antidiabetic properties, decreases body weight and also inhibits glucose absorption. Several components extracted from Gymnema prevent the accumulation of triglycerides in muscle and liver, and also decrease fatty acid accumulation in the circulation. In this paper, an attempt has been made to review the effects of various extracts from Gymnema sylvestre in the regulation of carbohydrate and lipid metabolism in both animal and clinical studies. © 2013 Society of Chemical Industry.

ACTION (Awareness, Care, and Treatment in Obesity maNagement) examined obesity-related perceptions, attitudes, and behaviors among people with obesity (PwO), health care providers (HCPs), and employer representatives (ERs). A total of 3,008 adult PwO (BMI ≥ 30 by self-reported height and weight), 606 HCPs, and 153 ERs completed surveys in a cross-sectional design. Despite several weight loss (WL) attempts, only 23% of PwO reported 10% WL during the previous 3 years. Many PwO (65%) recognized obesity as a disease, but only 54% worried their weight may affect future health. Most PwO (82%) felt "completely" responsible for WL; 72% of HCPs felt responsible for contributing to WL efforts; few ERs (18%) felt even partially responsible. Only 50% of PwO saw themselves as "obese," and 55% reported receiving a formal diagnosis of obesity. Despite HCPs' reported comfort with weight-related conversations, time constraints deprioritized these efforts. Only 24% of PwO had a scheduled follow-up to initial weight-related conversations. Few PwO (17%) perceived employer-sponsored wellness offerings as helpful in supporting WL. Although generally perceived as a disease, obesity is not commonly treated as such. Divergence in perceptions and attitudes potentially hinders better management. This study highlights inconsistent understanding of the impact of obesity and need for both self-directed and medical management. © 2017 The Obesity Society.

Bariatric surgery (BSx) produces clinically relevant weight loss that translates into improved quality of life, decreased mortality, and reduction in medical comorbidities, including cardiovascular (CV) risk. Little is known about patients' decision-making process to undergo BSx, but risk perception is known to influence medical decision-making. This study examined CV and BSx risk perception in obese subjects undergoing BSx (n = 268) versus those managed medically (MM) (n = 273). This retrospective population-based survey of subjects evaluated for BSx had 148 (55%) and 88 (32%) responders in the BSx and MM groups, respectively. Survey questions assessed risk perceptions and habits prior to weight loss intervention. CV risk was calculated using the Framingham Risk Score (FRS). At baseline, BSx subjects had a greater body mass index and greater prevalence of diabetes and depression. Follow-up mean weight loss was greater in the BSx group. BSx subjects perceived obesity as a greater risk to their overall health than the surgical risk. FRS declined in the BSx group (10 to 5%; p < 0.001) while there was no change in the MM group (8 to 8%; p = 0.54). Those without a measurable decrease in CV risk had a greater tendency to perceive the risk of BSx as greater than that of obesity. Obese subjects undergoing BSx are more likely than MM subjects to perceive obesity as a greater risk to their health than BSx. MM subjects generally underestimate their CV risk and overestimate the risk of BSx. Active discussion of CV risk using the FRS and the perception of risk associated with bariatric surgery can enhance patients' ability to make an informed decision regarding their management. © The European Society of Cardiology 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Obesity is increasingly being linked to the risk of developing and dying from cancer. In recognition of the growing contribution of obesity to cancer risk and outcomes, ASCO made obesity and cancer one of its core initiatives in 2014. The goals of this initiative included raising awareness of the relationship between obesity and cancer, providing tools and resources to oncology providers and patients to help encourage conversations regarding weight management in cancer survivors, fostering a robust research agenda, and advocating for access to evidence-based weight management programs for cancer survivors. Efforts to date have included developing patient and provider toolkits focused on weight management and physical activity, publishing a policy statement outlining ASCO's initiatives in this area, and hosting a summit focused on obesity research in cancer populations. As ASCO has defined its priorities in the area of obesity and cancer, it has become increasingly clear that obesity is a problem that extends far beyond its impact on cancer risk and outcomes. Many groups, including those focused on heart disease, diabetes, and endocrinology, have been developing, testing, and implementing obesity prevention and treatment strategies for years. As ASCO moves forward with its obesity initiative, the next steps will focus on forging collaboration with groups working on obesity-related initiatives both within and outside of the field of cancer to learn from their efforts and to partner with them on efforts to increase the education of medical professionals; raising awareness in lay populations regarding the negative health consequences of obesity and effective strategies to foster weight loss; developing collaborative research initiatives; and working together to advocate for the societal changes that will be needed to combat the obesity epidemic in the United States and beyond.
Obesity, Inflammation, and Cancer.
Deng, Tuo; Lyon, Christopher J; Bergin, Stephen; Caligiuri, Michael A; Hsueh, Willa A
2016-05-23
Obesity, a worldwide epidemic, confers increased risk for multiple serious conditions, including cancer, and is increasingly recognized as a growing cause of preventable cancer risk. Chronic inflammation, a well-known mediator of cancer, is a central characteristic of obesity, leading to many of its complications, and obesity-induced inflammation confers additional cancer risk beyond obesity itself. Multiple mechanisms facilitate this strong association between cancer and obesity. Adipose tissue is an important endocrine organ, secreting several hormones, including leptin and adiponectin, and chemokines that can regulate tumor behavior, inflammation, and the tumor microenvironment. Excessive adipose expansion during obesity causes adipose dysfunction and inflammation to increase systemic levels of proinflammatory factors. Cells from adipose tissue, such as cancer-associated adipocytes and adipose-derived stem cells, enter the cancer microenvironment to enhance protumoral effects. Dysregulated metabolism that stems from obesity, including insulin resistance, hyperglycemia, and dyslipidemia, can further impact tumor growth and development. This review describes how adipose tissue becomes inflamed in obesity, summarizes ways these mechanisms impact cancer development, and discusses their role in four adipose-associated cancers that demonstrate elevated incidence or mortality in obesity.

This study examined the impact of U.S. chain restaurant food consumption in China and South Korea from an ecological perspective. Specifically, it explored the relationships among several environmental and individual variables that have been found to affect obesity/weight management in previous research, including the prevalence/popularity of U.S. chain restaurants in these countries, frequency of U.S. chain restaurant food consumption, self-efficacy in weight management, willingness to communicate about weight/diet, self-perceptions of weight/obesity stigma, body mass index (BMI), and depression. The results indicated that willingness to communicate about weight/diet predicted increased self-efficacy in weight management. Higher BMI scores were found to predict increased weight/obesity stigma, and increased frequency of U.S. restaurant food consumption, weight/obesity stigma, and reduced self-efficacy in weight management were found to predict increased levels of depression. The theoretical and practical implications of the findings are discussed, along with limitations and directions for future research.
Development of an Obesity Prevention Dashboard for Wisconsin.
Ryan, Karissa; Pillai, Parvathy; Remington, Patrick L; Malecki, Kristen; Lindberg, Sara
2016-11-01
A comprehensive obesity surveillance system monitors obesity rates along with causes and related health policies, which are valuable for tracking and identifying problems needing intervention. A statewide obesity dashboard was created using the County Health Rankings model. Indicators were obtained through publicly available secondary data sources and used to rank Wisconsin amongst other states on obesity rates, health factors, and policies. Wisconsin consistently ranks in the middle of states for a majority of indicators and has not implemented any of the evidence-based health policies. This state of obesity report shows Wisconsin has marked room for improvement regarding obesity prevention, especially with obesity-related health policies. Physicians and health care systems can play a pivotal role in making progress on obesity prevention.
A one-way text messaging intervention for obesity.
Ahn, Ahleum; Choi, Jaekyung

Worldwide, there has been a startling increase in the number of people who are obese or overweight. Obesity increases the risk of cardiovascular disease and overall mortality. Mobile phone messaging is an important means of human communication globally. Because the mobile phone can be used anywhere at any time, mobile phone messaging has the potential to manage obesity. We investigated the effectiveness of a one-way text messaging intervention for obesity. Participants' body mass index and waist circumference were measured at the beginning of the programme and again after 12 weeks. The text message group received text messages about exercise, dietary intake, and general information about obesity three times a week, while the control group did not receive any text messages from the study. Of the 80 participants, 25 subjects in the text message group and 29 participants in the control group completed the study. After adjusting for baseline body mass index, the body mass index was significantly lower in the text message group than in the control group (27.9 vs. 28.3; p = 0.02). After adjusting for the baseline waist circumference, the difference of waist circumference between the text message group and control group was not significant (93.4 vs. 94.6; p = 0.13). The one-way text messaging intervention was a simple and effective way to manage obesity. The one-way text messaging intervention may be a useful method for lifestyle modification in obese subjects. © The Author(s) 2015.
Low muscle mass--tall and obese children a special genre of obesity.
Ralt, Dina
2007-01-01
The prevalence of over-weight and obesity has increased markedly in the last two decades and vast international resources have been directed toward researching these issues. Obesity would appear to be a problem that is easy to resolve: just eat less and move more. However, this very common condition has turned out to be extremely troublesome, and in some cases even insolvable. A perspective is presented here suggesting that some of the insoluble cases of obesity are the result of an inborn condition of a very low muscle mass. The interplay between less muscle and more fat tissue is discussed from physiological and environmental perspectives with an emphasis on the early years of childhood. It is proposed that these interactions lead to bodily economic decisions sliding between thrift or prodigal strategies. The thrift strategy results not only in obesity and less physical activity but also in other maladies which the body is unable to manage. What leads to obesity (less muscle, more fat) in the medial population will result in morbid obesity when the children are short of muscle tissue from the start. Attempts to lessen the consequences of low muscle mass, which might be very difficult at adulthood, can be more fruitful if initiated at childhood. Early recognition of the ailment is thus crucial. Based on studies demonstrating a 'rivalry' between muscle build-up and height growth at childhood, it is postulated that among the both taller and more obese children the percentage of children with lower muscle mass will be significant. A survey of the height and BMI (Body Mass Index) of Israeli fifth graders supports this postulation. A special, body/muscle-building gymnastics program for children is suggested as a potential early intervention to partially prevent this type of almost irreversible ill progress of obesity.
Obesity, insulin resistance, and type 1 diabetes mellitus.
Polsky, Sarit; Ellis, Samuel L
2015-08-01
To summarize recent studies about obesity, insulin resistance, and type 1 diabetes mellitus (T1DM). Overweight and obesity continue to be prevalent among individuals with T1DM. Obesity rates appear to have reached a plateau among children with T1DM in some parts of the world. The risk for development of T1DM is increased by obesity and may occur at an earlier age among obese individuals with a predisposition. Obesity increases the risk for comorbidities among individuals with T1DM, especially metabolic syndrome, and microvascular and macrovascular diseases. Metformin, glucagon-like peptide-1 agonist therapy, sodium glucose cotransporter-2 inhibitor therapy, and bariatric surgery may be beneficial therapies for glucose control, comorbidity management, and obesity among adults with T1DM. Insulin resistance may be improved among obese individuals with T1DM by biguanides (metformin) and glucagon-like peptide-1 agonists (exenatide). We review the last 18 months of literature on obesity, insulin resistance, and T1DM to highlight new epidemiologic results and treatments.
Glucagon-like peptide 1 in the pathophysiology and pharmacotherapy of clinical obesity
Anandhakrishnan, Ananthi; Korbonits, Márta
2016-01-01
Though the pathophysiology of clinical obesity is undoubtedly multifaceted, several lines of clinical evidence implicate an important functional role for glucagon-like peptide 1 (GLP-1) signalling. Clinical studies assessing GLP-1 responses in normal weight and obese subjects suggest that weight gain may induce functional deficits in GLP-1 signalling that facilitates maintenance of the obesity phenotype. In addition, genetic studies implicate a possible role for altered GLP-1 signalling as a risk factor towards the development of obesity. As reductions in functional GLP-1 signalling seem to play a role in clinical obesity, the pharmacological replenishment seems a promising target for the medical management of obesity in clinical practice. GLP-1 analogue liraglutide at a high dose (3 mg/d) has shown promising results in achieving and maintaining greater weight loss in obese individuals compared to placebo control, and currently licensed anti-obesity medications. Generally well tolerated, provided that longer-term data in clinical practice supports the currently available evidence of superior short- and long-term weight loss efficacy, GLP-1 analogues provide promise towards achieving the successful, sustainable medical management of obesity that remains as yet, an unmet clinical need.

Canine patients are generally regarded as being clinically obese when their body weight is at least 15% above ideal. The incidence of obesity in dogs is thought to be in the range of 20-40% of the general population and, since obesity is known to predispose or exacerbate a range of serious medical conditions, its importance cannot be overstated. Management of obesity through dietary restriction and increased exercise is often difficult to achieve and dependent upon owner compliance. Until recently there has been no authorized therapeutic medication available for weight reduction in dogs, and drugs used in people have proved unsuitable. However, with the development of microsomal triglyceride transfer protein inhibitors for canine use, such as dirlotapide, the veterinarian has a novel method with which to augment traditional weight control programmes. This approach has the additional advantage that weight loss is achieved without dietary restriction or change in exercise regimen, providing encouragement for the owner to comply with subsequent dietary and exercise recommendations, thereby increasing the likelihood for long-term success.

Ghrelin is an endogenous appetite stimulant that may have a role in ovarian function. Women with polycystic ovary syndrome have anovulation and frequently weight management issues; however the associations between ghrelin and hormonal markers in polycystic ovary syndrome have not been well studied. In order to characterize the association between total ghrelin levels and ovarian function and the possible modification of this relationship by obesity, we examined total ghrelin levels and anti-mullerian hormone, total testosterone, and insulin in obese and non-obese women with and without polycystic ovary syndrome. Total ghrelin levels were lower in obese women with polycystic ovary syndrome (n = 45) compared to obese controls (n = 33) (p = 0.005), but similar in non-obese women with polycystic ovary syndrome (n = 20) compared to non-obese controls (n = 21) (p = NS). In the obese polycystic ovary syndrome group, anti-mullerian hormone was associated with ghrelin levels independent of age, insulin, and total testosterone (p = 0.008). There was no association between total ghrelin and anti-mullerian hormone levels in non-obese women with polycystic ovary syndrome, non-obese controls, or obese controls (p = NS). Our results provide evidence for a potential relationship between ghrelin and ovarian function in obese women with polycystic ovary syndrome that was not observed in non-obese women with polycystic ovary syndrome or controls.

Obesity is a global public health problem and a risk factor for several diseases that financially impact healthcare systems. To estimate the direct costs attributable to obesity (body mass index {BMI} ≥ 30 kg/m2) and morbid obesity (BMI ≥ 40 kg/m2) in adults aged ≥ 20 incurred by the Brazilian public health system in 2011. Public hospitals and outpatient care. A cost-of-illness method was adopted using a top-down approach based on prevalence. The proportion of the cost of each obesity-associated comorbidity was calculated and obesity prevalence was used to calculate attributable risk. Direct healthcare cost data (inpatient care, bariatric surgery, outpatient care, medications and diagnostic procedures) were extracted from the Ministry of Health information systems, available on the web. Direct costs attributable to obesity totaled US$ 269.6 million (1.86% of all expenditures on medium- and high-complexity health care). The cost of morbid obesity accounted for 23.8% (US$ 64.2 million) of all obesity-related costs despite being 18 times less prevalent than obesity. Bariatric surgery costs in Brazil totaled US$ 17.4 million in 2011. The cost of morbid obesity in women was five times higher than it was in men. The cost of morbid obesity was found to be proportionally higher than the cost of obesity. If the current epidemic were not reversed, the prevalence of obesity in Brazil will increase gradually in the coming years, as well as its costs, having serious implications for the financial sustainability of the Brazilian public health system.
Obesity and Heart Failure: Focus on the Obesity Paradox.
Carbone, Salvatore; Lavie, Carl J; Arena, Ross
2017-02-01
The escalating prevalence of obesity has been linked to substantial increases in both metabolic and cardiovascular disease. Nevertheless, the direct effects of obesity on cardiovascular health and function require further exploration. In particular, the relationship between obesity and cardiac function has received intense scrutiny. Although obesity increases the risk for development of heart failure (HF), it appears to exert a protective effect in patients in whom HF has already been diagnosed (the "obesity paradox"). The protective effects of obesity in patients with previously diagnosed HF are the focus of particularly intense research. Several explanations have been proposed, but most studies are limited by the use of body mass index to classify obesity. Because body mass index does not distinguish between fat mass, fat-free mass, and lean mass, individuals with similar body mass indices may have vastly different body composition. This article discusses the roles of body composition, diet, cardiorespiratory fitness, and weight loss in the development of cardiac dysfunction and HF and the potential protective role that body composition compartments might play in improving HF prognosis. Based on an intensive literature search (Pubmed, Google Scholar) and critical review of the literature, we also discuss how a multidisciplinary approach including a nutritional intervention targeted to reduce systemic inflammation and lean mass-targeted exercise training could potentially exert beneficial effects for patients with HF.

Background State-level estimates from the Centers for Disease Control and Prevention (CDC) underestimate the obesity epidemic because they use self-reported height and weight. We describe a novel bias-correction method and produce corrected state-level estimates of obesity and severe obesity. Methods Using non-parametric statistical matching, we adjusted self-reported data from the Behavioral Risk Factor Surveillance System (BRFSS) 2013 (n = 386,795) using measured data from the National Health and Nutrition Examination Survey (NHANES) (n = 16,924). We validated our national estimates against NHANES and estimated bias-corrected state-specific prevalence of obesity (BMI≥30) and severe obesity (BMI≥35). We compared these results with previous adjustment methods. Results Compared to NHANES, self-reported BRFSS data underestimated national prevalence of obesity by 16% (28.67% vs 34.01%), and severe obesity by 23% (11.03% vs 14.26%). Our method was not significantly different from NHANES for obesity or severe obesity, while previous methods underestimated both. Only four states had a corrected obesity prevalence below 30%, with four exceeding 40%–in contrast, most states were below 30% in CDC maps. Conclusions Twelve million adults with obesity (including 6.7 million with severe obesity) were misclassified by CDC state-level estimates. Previous bias-correction methods also resulted in underestimates. Accurate state-level estimates are necessary to plan for resources to address the obesity epidemic. PMID:26954566

[Possibilities of mobile applications for managing obesity according to professionals].
Aguilar-Martínez, Alicia; Tort, Elena; Medina, F Xavier; Saigí-Rubió, Francesc
2015-01-01
Given the increasing use and importance of mobile telephone applications (apps) in the health setting, this study aimed to ascertain the views of health professionals involved in the treatment of obesity about their current needs and gaps in their requirements, their willingness to use mobile apps, and the features these devices should have for the treatment of obesity. A qualitative study was conducted through semi-structured interviews with experts treating obesity. The experts believed that apps could be useful to interact or deal with patients. However, their willingness to use apps contrasts with the current limited use of these devices. Practitioners felt that apps could partly compensate for the lack of daily contact between patients and professionals and could increase interaction with patients, achieving more favourable weight control results, especially with regard to improved adherence and motivation. In terms of the functionality and requirements of such apps, the main elements to be included were records of weight, physical activity and food consumption. Adding apps to the existing treatment of overweight and obesity still requires further definition of its functions. Additionally, further investigation is needed into both the role and involvement of professionals in the design process and during treatment. Copyright © 2015 SESPAS. Published by Elsevier Espana.

Obesity services: how best to develop a coherent way forward.
Barth, Julian H; O'Kane, Mary
2016-03-01
Obesity now affects 25% of the UK population. This volume of patients cannot be managed by current NHS services. It really needs a public health approach which encourages an environment where it is easier for the public to take healthy rather than unhealthy actions. However, there remain substantial numbers of patients who will benefit from medical intervention. This needs a joined-up service which extends from a healthy environment, linking gyms, weight loss groups, community cooking lessons, etc. with pathways connecting primary and secondary healthcare. To date, the National Health Service has not managed to develop a coherent policy that addresses obesity as a major cause of health and social care expenditure. The most important step in primary care is probably to identify the presence of obesity. The medical steps should be in the identification and management of comorbidities. The purpose of treating obesity is not weight loss alone but improving health, so the narrative needs to change from weight to blood pressure, glucose tolerance, physical fitness, etc. Many physicians believe that weight loss is an unwinnable battle but there are several well conducted studies in which primary care, supported by specialists, can deliver successful clinical weight loss. Specialist medical and surgical care for obesity will be required for complex cases and is essential for overseeing long-term postsurgical follow-up to prevent and treat nutritional and metabolic complications. Obesity management suffers from a lack of coherent national public health policies, fragmentation of care and a lack of knowledge of what successful treatment entails. Health benefits do not require a return to a healthy BMI. © 2015 John Wiley & Sons Ltd.
The Treatment of Achalasia in Obese Patients.
Wesp, Julie A; Farrell, Timothy M
2018-04-01
Epidemiological studies have demonstrated that obesity is frequently associated with esophageal motility disorders. Morbid obesity and achalasia may coexist in the same patient. The management of the morbidly obese patient with achalasia is complex and the most effective treatment remains controversial. The aim of this study is to review the pathophysiology, clinical presentation, diagnostic evaluation, and treatment of achalasia in morbidly obese patients. PubMed search from January 1990 to July 2017, including the following terms: achalasia, morbid obesity, bariatric, and treatment. Achalasia in the setting of morbid obesity may be successfully treated by endoscopic or surgical methods. Surgeons may choose to add a bariatric procedure, with various strategies present in the literature. A review of the present literature suggests that the preferred approach to achalasia in the morbidly obese patient is to address both disease processes simultaneously with a laparoscopic Heller myotomy and a Roux-en-Y gastric bypass. Roux-en-Y gastric bypass is cited by most experts as the bariatric procedure of choice, given its antireflux benefits. A well-powered study, comparing the various approaches to the treatment of achalasia in the setting of morbid obesity, is required to establish a consensus.
Ciliary dysfunction and obesity.
Mok, C A; Héon, E; Zhen, M
2010-01-01
Obesity associates with increased health risks such as heart disease, stroke and diabetes. The steady rise in the obese population worldwide poses an increasing burden on health systems. Genetic factors contribute to the development of obesity, and the elucidation of their physiological functions helps to understand the cause, and improve the prevention, diagnosis and treatment for this disorder. Primary cilia are evolutionarily conserved organelles whose dysfunctions lead to human disorders now defined as ciliopathies. Human ciliopathies present pleiotropic and overlapping phenotypes that often include retinal degeneration, cystic renal anomalies and obesity. Increasing evidence implicates an intriguing involvement of cilia in lipid/energy homeostasis. Here we discuss recent studies in support of the key roles of ciliary genes in the development and pathology of obesity in various animal models. Genes affecting ciliary development and function may pose promising candidate underlying genetic factors that contribute to the development of common obesity.

Public health related tweets are difficult to identify in large conversational datasets like Twitter.com. Even more challenging is the visualization and analyses of the spatial patterns encoded in tweets. This study has the following objectives: How can topic modeling be used to identify relevant public health topics such as obesity on Twitter.com? What are the common obesity related themes? What is the spatial pattern of the themes? What are the research challenges of using large conversational datasets from social networking sites? Obesity is chosen as a test theme to demonstrate the effectiveness of topic modeling using Latent Dirichlet Allocation (LDA) and spatial analysis using Geographic Information System (GIS). The dataset is constructed from tweets (originating from the United States) extracted from Twitter.com on obesity-related queries. Examples of such queries are 'food deserts', 'fast food', and 'childhood obesity'. The tweets are also georeferenced and time stamped. Three cohesive and meaningful themes such as 'childhood obesity and schools', 'obesity prevention', and 'obesity and food habits' are extracted from the LDA model. The GIS analysis of the extracted themes show distinct spatial pattern between rural and urban areas, northern and southern states, and between coasts and inland states. Further, relating the themes with ancillary datasets such as US census and locations of fast food restaurants based upon the location of the tweets in a GIS environment opened new avenues for spatial analyses and mapping. Therefore the techniques used in this study provide a possible toolset for computational social scientists in general and health researchers in specific to better understand health problems from large conversational datasets.
New trends on obesity and NAFLD in Asia.
Fan, Jian-Gao; Kim, Seung-Up; Wong, Vincent Wai-Sun
2017-10-01
Traditionally, obesity and its related diseases have been considered a problem in Western countries. However, in the past two decades, urbanisation in many Asian countries has led to a sedentary lifestyle and overnutrition, setting the stage for the epidemic of obesity. This article reviews the epidemiological trend of obesity in Asia, with special emphasis on the emerging condition of non-alcoholic fatty liver disease (NAFLD). Currently, the population prevalence of NAFLD in Asia is around 25%, like many Western countries. While hepatocellular carcinoma and end-stage liver disease secondary to NAFLD remain uncommon, a rising trend has emerged. Around 8-19% of Asians with body mass indexes less than 25kg/m 2 are also found to have NAFLD, a condition often described as "lean" or "non-obese" NAFLD. Although this condition is generally less severe than that in more obese patients, steatohepatitis and fibrotic disease are well recognized. Central adiposity, insulin resistance and weight gain are major risk factors, and genetic predisposition, such as the PNPLA3 polymorphism appears to be more important in the development of NAFLD in the non-obese population. Lifestyle modification remains the cornerstone of management for obesity and NAFLD, but few patients can achieve adequate weight reduction and even fewer can maintain the weight in the long run. While pharmacological agents have entered phase III development for steatohepatitis, Asian patients are under-represented in most drug trials. Future studies should define the optimal management of obesity and NAFLD in Asia. Copyright © 2017 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

Obesity is globally the most prevalent nutritional disorder. Multifaceted therapeutic approaches are called for to halt the cascade from neonatal adiposity/high birth weight to childhood excessive weight gain/adult obesity with comorbidities. Recent experimental and clinical data provide one new target for interventions aiming to close this vicious circle: the microbiota. An aberrant gut microbiota, dysbiosis, induces immune and metabolic disturbances both locally and, consequent upon impaired gut barrier function, also systemic low-grade inflammation, which is causally linked to insulin resistance. The gut microecology could thus fill the gap between energy intake and expenditure by processing nutrients and regulating their access to and storage in the body, producing chemicals of hormonal nature and controlling the secretion of proinflammatory mediators locally and systemically. Conversely, being highly sensitive to environmental impacts, particularly to early feeding, the compositional development of the gut microbiota may prove the target of choice in efforts to reduce the risk of obesity. It has been demonstrated that a lower number of bifidobacteria precedes the development of obesity, and a dearth of butyrate-producing bacteria and an overall richness of bacteria increase the risk of metabolic disease; moreover, recognition that practices known to disrupt the early gut microbiota, e.g., cesarean section delivery and antibiotic exposure, contribute to obesity, encourages to pursue this line of research. © 2017 Nestec Ltd., Vevey/S.

For unclear reasons, obese children with asthma have higher morbidity and reduced response to inhaled corticosteroids. To assess whether childhood obesity is associated with airway dysanapsis (an incongruence between the growth of the lungs and the airways) and whether dysanapsis is associated with asthma morbidity. We examined the relationship between obesity and dysanapsis in six cohorts of children with and without asthma, as well as the relationship between dysanapsis and clinical outcomes in children with asthma. Adjusted odds ratios (ORs) were calculated for each cohort and in a combined analysis of all cohorts; longitudinal analyses were also performed for cohorts with available data. Hazard ratios (HRs) for clinical outcomes were calculated for children with asthma in the Childhood Asthma Management Program. Being overweight or obese was associated with dysanapsis in both the cross-sectional (OR, 1.95; 95% confidence interval [CI], 1.62-2.35 [for overweight/obese compared with normal weight children]) and the longitudinal (OR, 4.31; 95% CI, 2.99-6.22 [for children who were overweight/obese at all visits compared with normal weight children]) analyses. Dysanapsis was associated with greater lung volumes (FVC, vital capacity, and total lung capacity) and lesser flows (FEV 1 and forced expiratory flow, midexpiratory phase), and with indicators of ventilation inhomogeneity and anisotropic lung and airway growth. Among overweight/obese children with asthma, dysanapsis was associated with severe disease exacerbations (HR, 1.95; 95% CI, 1.38-2.75) and use of systemic steroids (HR, 3.22; 95% CI, 2.02-5.14). Obesity is associated with airway dysanapsis in children. Dysanapsis is associated with increased morbidity among obese children with asthma and may partly explain their reduced response to inhaled corticosteroids.

Severe obesity (SO) in pediatrics has become increasing prevalent in recent decades.The objective of our study was to examine differences in demographic, anthropometric, cardiometabolic, and lifestyle variables in children and youth with SO versus their less overweight/obese (OW/OB) peers. A retrospective medical record review of 6-19 year old participants enrolled in an outpatient pediatric weight management clinic was conducted. SO (body mass index [BMI] ≥99(th) percentile) and OW/OB (BMI ≥85(th) and <99(th) percentile) groups were created according to Centers for Disease Control and Prevention definitions. Demographic, anthropometric, cardiometabolic and lifestyle data reported at baseline (pre-intervention) were retrieved. Of the 345 participants, most were girls (56.2%), Caucasian (78.7%), and had family incomes > $50,000/year (65.7%). The SO group (n = 161) had lower HDL-cholesterol and higher liver enzymes, insulin resistance and blood pressure than the OW/OB group (n = 184; all p < 0.01). They also reported higher total energy intakes, fewer steps/day, less moderate-to-vigorous physical activity, and more leisure time screen time (all p < 0.02) than their leaner peers. Compared to the OW/OB group, a higher proportion of individuals in the SO group possessed cardiometabolic risk factors, including high triglycerides (45.8% vs 58.5%), alanine aminotransferase (55.4% vs 81.4%), insulin resistance (55.6% vs 82.1%), systolic blood pressure (11.5% vs 27.3%), diastolic blood pressure (17.8% vs 30.0%), and low HDL-cholesterol (44.6% vs 64.6%; all p < 0.02). Aside from the ~75% of participants (groups combined) who met the daily recommended intakes of grain and meat products, <50% of boys and girls met any of the remaining nutrition and physical activity-related recommendations. Compared to the OW/OB group, greater proportions of children and youth in the SO group failed to meet moderate-to-vigorous physical activity (48.4% vs 31.9%) and leisure

Obesity is the result of a complex interplay among several factors leading to medical, functional and psychosocial consequences that markedly reduce life expectancy and impair quality of life. Is obesity itself a disease? Is obesity a brain disease? Who should treat obesity? This paper is a narrative review aimed to describe and to argue the prevalent position of some major Italian scientific and academic institutions dealing with obesity. According to the recent statements and recommendations published by the Italian Society for Obesity (SIO) and the Italian Society for the Study of Eating Disorders (SISDCA), the management of obese patients should include five main levels of care: (1) primary care, (2) outpatient treatment, (3) intensive outpatient treatment, (4) residential rehabilitative treatment, and (5) hospitalization. Ideally, patients suffering from obesity need a multidimensional evaluation intended to design an individualized treatment plan applying different procedures and therapeutic strategies (diet, physical activity and functional rehabilitation, educational therapy, cognitive-behavior therapy, drug therapy, and bariatric surgery). This thorough approach should address not only weight loss but also quality of weight loss, medical and psychiatric comorbidity, psychosocial problems, and physical disability. Such management of obesity requires an effective multiprofessional team, while health services have to overcome a number of administrative and organizational barriers that do not account for diseases requiring resources and professionals from different areas of medicine. Integrating several competences in a team-based approach demands specific education, skills and expertise. As for other diseases, the principles of complexity theory may offer a model useful to implement both teamwork and care delivery for patients with obesity.

The glyoxalase system in the cytoplasm of cells provides the primary defence against glycation by methylglyoxal catalysing its metabolism to D-lactate. Methylglyoxal is the precursor of the major quantitative advanced glycation endproducts in physiological systems - arginine-derived hydroimidazolones and deoxyguanosine-derived imidazopurinones. Glyoxalase 1 of the glyoxalase system was linked to anthropometric measurements of obesity in human subjects and to body weight in strains of mice. Recent conference reports described increased weight gain on high fat diet-fed mouse with lifelong deficiency of glyoxalase 1 deficiency, compared to wild-type controls, and decreased weight gain in glyoxalase 1-overexpressing transgenic mice, suggesting a functional role of glyoxalase 1 and dicarbonyl stress in obesity. Increased methylglyoxal, dicarbonyl stress, in white adipose tissue and liver may be a mediator of obesity and insulin resistance and thereby a risk factor for development of type 2 diabetes and non-alcoholic fatty liver disease. Increased methylglyoxal formation from glyceroneogenesis on adipose tissue and liver and decreased glyoxalase 1 activity in obesity likely drives dicarbonyl stress in white adipose tissue increasing the dicarbonyl proteome and related dysfunction. The clinical significance will likely emerge from on-going clinical evaluation of inducers of glyoxalase 1 expression in overweight and obese subjects. Increased transcapillary escape rate of albumin and increased total body interstitial fluid volume in obesity likely makes levels of glycation of plasma protein unreliable indicators of glycation status in obesity as there is a shift of albumin dwell time from plasma to interstitial fluid, which decreases overall glycation for a given glycemic exposure.

Food is a potent natural reward and food intake is a complex process. Reward and gratification associated with food consumption leads to dopamine (DA) production, which in turn activates reward and pleasure centers in the brain. An individual will repeatedly eat a particular food to experience this positive feeling of gratification. This type of repetitive behavior of food intake leads to the activation of brain reward pathways that eventually overrides other signals of satiety and hunger. Thus, a gratification habit through a favorable food leads to overeating and morbid obesity. Overeating and obesity stems from many biological factors engaging both central and peripheral systems in a bi-directional manner involving mood and emotions. Emotional eating and altered mood can also lead to altered food choice and intake leading to overeating and obesity. Research findings from human and animal studies support a two-way link between three concepts, mood, food, and obesity. The focus of this article is to provide an overview of complex nature of food intake where various biological factors link mood, food intake, and brain signaling that engages both peripheral and central nervous system signaling pathways in a bi-directional manner in obesity.

The objective of an operations management system is to provide an orderly and efficient method to operate and maintain aerospace vehicles. Concepts are described for an operations management system and the key technologies are highlighted which will be required if this capability is brought to fruition. Without this automation and decision aiding capability, the growing complexity of avionics will result in an unmanageable workload for the operator, ultimately threatening mission success or survivability of the aircraft or space system. The key technologies include expert system application to operational tasks such as replanning, equipment diagnostics and checkout, global system management, and advanced man machine interfaces. The economical development of operations management systems, which are largely software, will require advancements in other technological areas such as software engineering and computer hardware.
New advances in models and strategies for developing anti-obesity drugs

Introduction Obesity is a worldwide pandemic. Obesity-related health and economic costs are staggering. Existing strategies to combat obesity through lifestyle improvements and medical intervention have had limited success. Pharmacotherapy, in combination with lifestyle modification, may play a vital role in reversing the disease burden. However, past and current weight-loss medications have had serious safety risks, notably cardiovascular and psychiatric events. Areas covered We review the strategies for designing new anti-obesity drugs by describing those currently in development. We describe their target, mechanism of action, and developmental or regulatory status. We also discuss the problem of weight regain following weight loss, and its relevance to the long-term success of anti-obesity pharmacotherapy. Expert opinion For weight management drugs to achieve the safety and efficacy required to be impactful, current studies are uncovering and characterizing new targets, including new signaling circuits and hormones regulating appetite and metabolism, and re-evaluating the role of pharmacotherapy in weight management. To avoid the safety failures of many past weight-loss drugs, the models and strategies covered in this article incorporate recent advances in knowledge and technology. We discuss the emergence of cGMP signaling as a potentially transformative target in weight management. Modulating cGMP signaling may represent an ideal goal for an anti-obesity pharmacotherapy, reflecting some of the major themes described in the present review: targeting pathways that are newly realized as relevant for weight management; promoting safety by re-purposing drugs that are safe, proven, and approved for clinical use; and having a synergistic effect on multiple, reinforcing pathways.

There is hardly any empirical evidence on emotion processing by controlled studies in obesity. Participants rated their emotions in response to visual emotional stimuli from the International Affective Picture System. Study 1 compared obese women with normal-weight controls and women with eating disorders. Study 2 compared obese men with normal-weight controls. Obese women had reduced emotional intensity scores for all basic emotions and the mixed emotion sadness-fear. Obese men had reduced scores for all emotions except happiness and disgust; anger showed a trend towards significance. The results were mainly based on ratings from non-depressed obese individuals. Obese men and women scored significantly lower on most basic and mixed emotions. Non-depressed obese subjects seem particularly affected. These new findings must be validated by further study, and longitudinal evaluation after weight loss, e.g. by bariatric surgery, will be of interest.

2017-07-01
After decades of rapid increase, the rate of obesity in adults in the USA is beginning to slow and the rate of childhood obesity is stabilizing. Despite these improvements, the obesity epidemic continues to be a major health and financial burden. Obesity is associated with serious negative health outcomes such as cardiovascular disease, type II diabetes, and, more recently, cognitive decline and various neurodegenerative dementias such as Alzheimer's disease. In the past decade, major advancements have contributed to the understanding of the role of the central nervous system (CNS) in the development of obesity and how peripheral hormonal signals modulate CNS regulation of energy homeostasis. In this article, we address how obesity affects the structure and function of the blood-brain barrier (BBB), the impact of obesity on Alzheimer's disease, the effects of obesity on circulating proteins and their transport into the brain, and how these changes can potentially be reversed by weight loss.

Depression and obesity are important in children because they affect health in childhood and later life. The exact relationship between obesity and depression, especially in children, remains undefined. Using a cross-sectional chart review design, our study looked at a weight management clinic-based sample of 117 obese children, 7 to 17 years old, to determine the relationship between absolute BMI and depression as measured by the Children's Depression Index (CDI) while accounting for confounders, such as the child's medical problems, physical activity, and family structure. There was no correlation between depression as measured by the CDI and increasing BMI in obese children seeking weight management. However, we did demonstrate a positive correlation between depression and paternal absence and daily television/computer/video game time. Clinicians should encourage decreasing screen time and might consider family therapy for obese children in families that lack paternal involvement.

Prospective patient registries have been successfully utilized in several disease states with a goal of improving treatment approaches through multi-institutional collaboration. The prevalence of youth with severe obesity is at a historic high in the United States, yet evidence to guide effective weight management is limited. The Pediatric Obesity Weight Evaluation Registry (POWER) was established in 2013 to identify and promote effective intervention strategies for pediatric obesity. Sites in POWER provide multicomponent pediatric weight management (PWM) care for youth with obesity and collect a defined set of demographic and clinical parameters, which they regularly submit to the POWER Data Coordinating Center. A program profile survey was completed by sites to describe characteristics of the respective PWM programs. From January 2014 through December 2015, 26 US sites were enrolled in POWER and had submitted data on 3643 youth with obesity. Ninety-five percent were 6-18 years of age, 54% female, 32% nonwhite, 32% Hispanic, and 59% publicly insured. Over two-thirds had severe obesity. All sites included a medical provider and used weight status in their referral criteria. Other program characteristics varied widely between sites. POWER is an established national registry representing a diverse sample of youth with obesity participating in multicomponent PWM programs across the United States. Using high-quality data collection and a collaborative research infrastructure, POWER aims to contribute to the development of evidence-based guidelines for multicomponent PWM programs.

The Centers for Medicare & Medicaid Services Electronic Health Record Meaningful Use Incentive Program requires physicians to document body mass index (BMI) and a follow-up treatment plan for adult patients with BMI ≥ 25. To examine the effect of a best practice alert on physician documentation of obesity-related care and referrals to weight management treatment, in a cluster-randomized design, 14 primary care clinics at an academic medical center were randomized to best practice alert intervention (n = 7) or comparator (n = 7). The alert was triggered when both height and weight were entered and BMI was ≥30. Both intervention and comparator clinics could document meaningful use by selecting a nutrition education handout within the alert. Intervention clinics could also select a referral option from the list of clinic and community-based weight management programs embedded in the alert. Main outcomes were proportion of eligible patients with (1) obesity-related documentation and (2) referral. There were 26,471 total primary care encounters with 12,981 unique adult patients with BMI ≥ 30 during the 6-month study period. Documentation doubled (17 to 33%) with implementation of the alert. However, intervention clinics were not significantly more likely to refer patients to weight management than comparator clinics (2.8 vs. 1.3%, p = 0.07). Although the alert was associated with increased physician meaningful use compliance, it was not an effective strategy for improving patient access to weight management services. Further research is needed to understand system-level characteristics that influence obesity management in primary care.

Severe obesity in adolescents has deleterious physical and psychological complications necessitating frequent multi-disciplinary clinic visits. Greater treatment engagement has been equated with weight-loss. However, traditional medical weight-loss programs for adolescents have high attrition rates. Social media is widely used by adolescents and may enhance medical weight management engagement and success. The first objective was to examine the acceptability and feasibility of using a private social media group as an adjunct to medical weight management in youth ages 14 to 20 years with severe obesity [body mass index (BMI) ≥ 35 kg/m2]. The second objective was to pilot test the use of social media to improve treatment engagement and decrease attrition rates. In this single arm, 12 week pre-post study, participants attended individual clinic visits and participated in a moderated private social media group that received nutrition, exercise, and behavior change social media communications or "posts" 3 to 4 times/week. Youth commented and/or liked posts from the moderator and each other. Social media engagement was measured with the number of likes and comments on social media. Clinic attrition was compared, measuring clinic visit attendance 12 weeks prior, during, and after the intervention with mixed linear regression models. Correlations of social media engagement with changes from baseline for BMI, BMI-z score, and psychosocial measures were fit. All 13 enrolled youth completed the study and reported that the group was enjoyable, helpful, reinforced their weight management program, and would recommend using social media to support other youth. The pilot trial was acceptable and feasible. Youth mean weekly engagement (likes + comments) in social media was greater than once a day (8.6 ±3.6). Compared to 12 weeks prior to the intervention, there was no significant decrease in clinic visit attendance at the end of the intervention (M=.231, P=.69) or 12 weeks at

To determine total dietary fiber (TDF) composition of feline diets used for management of obesity and diabetes mellitus. Cross-sectional survey. Dry veterinary (n = 10), canned veterinary (12), and canned over-the-counter (3) feline diets. Percentage of TDF as insoluble dietary fiber (IDF), high-molecular-weight soluble dietary fiber (HMWSDF), and low-molecular-weight soluble dietary fiber (LMWSDF) was determined. Median measured TDF concentration was greater than reported maximum crude fiber content in dry and canned diets. Median TDF (dry-matter) concentration in dry and canned diets was 12.2% (range, 8.11% to 27.16%) and 13.8% (range, 4.7% to 27.9%), respectively. Dry and canned diets, and diets with and without a source of oligosaccharides in the ingredient list, were not different in energy density or concentrations of TDF, IDF, HMWSDF, or LMWSDF. Similarly, loaf-type (n = 11) and gravy-type (4) canned diets differed only in LMWSDF concentration. Disparities in TDF concentrations among products existed despite a lack of differences among groups. Limited differences in TDF concentration and dietary fiber composition were detected when diets were compared on the basis of carbohydrate concentration. Diets labeled for management of obesity were higher in TDF concentration and lower in energy density than diets for management of diabetes mellitus. Diets provided a range of TDF concentrations with variable concentrations of IDF, HMWSDF, and LMWSDF. Crude fiber concentration was not a reliable indicator of TDF concentration or dietary fiber composition. Because carbohydrate content is calculated as a difference, results suggested that use of crude fiber content would cause overestimation of both carbohydrate and energy content of diets.

Weight loss studies were conducted in children without asthma have demonstrated a reduction in systemic inflammation. However, the impact of weight loss in the obese paediatric population with asthma has not been investigated. To measure the effects of weight loss on markers of systemic inflammation in obese children with bronchial asthma. Eighty obese children with bronchial asthma (42 boys, and 38 girls) with mean age 13.86 ± 3.21 years were divided into two equal groups. The training group received diet regimen, exercise training in addition to the medical treatment for two months, where the control group received the medical treatment only. There was a 17.5%, 15.5%, 22.4%, 14.1% and 15.9% reduction in mean values of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), interleukin-8 (IL-8), Leptin and body mass index (BMI) respectively and 38.7 % increase in mean values of adiponectin in the training group. While, there was a 0.7%, 9.0%, 2.8%, 1.6% and 1.2% increase in mean values of TNF-alpha, IL-6, IL-8, Leptin and BMI respectively and 3.9% decrease in mean values of adiponectin in the control group. The mean values of TNF-alpha, IL-6, IL-8, Leptin and BMI was decreased and adiponectin was increased significantly in the training group, however the results of the control group were not significant. Also, there were significant differences between both groups at the end of the study. Weight loss improves markers of systemic inflammation in obese Saudi children with bronchial asthma.

Background Obesity is a serious and costly disease that is growing in epidemic proportions. Obesity-related hospitalizations have nearly tripled from 1996 to 2009. If the current trend in the growth of obesity continues, the total healthcare costs attributable to obesity could reach $861 billion to $957 billion by 2030. The American Medical Association has officially recognized obesity as a disease. Obesity is a public health crisis affecting approximately more than 33% of Americans and costing the healthcare system more than $190 billion annually. Objectives To review the 2 new drugs that were recently approved by the US Food and Drug Administration (FDA) for the treatment of obesity, lorcaserin HCl (Belviq) and phentermine/topiramate (Qsymia) and their potential impact on the treatment of obese patients. Discussion Lifestyle modification is the first and mainstay treatment for obesity. Antiobesity drugs are indicated as adjuncts to a healthy, low-fat, low-calorie diet and an exercise plan. Currently, 4 drugs are approved by the FDA for the treatment of obesity, 2 of which were approved after June 2012. These 2 drugs, Belviq and Qsymia, have added new tools for the treatment of obesity. In addition to reducing body mass index, these drugs have been shown to reduce hemoglobin A1c levels in patients with diabetes and blood pressure levels in patients with hypertension, as well as to decrease lipid levels in patients with hyperlipidemia. This article reviews the drugs' mechanisms of action, evaluates landmark clinical studies leading to the FDA approval of the 2 drugs, their common side effects, and the benefits these new drugs can provide toward the management of the obesity epidemic that are different from other medications currently available. Conclusion The weight loss seen in patients who are using the 2 new medications has been shown to further improve other cardiometabolic health parameters, including blood pressure, blood glucose levels, and serum lipid
Obesity in Childhood Cancer Survivors: Call for Early Weight Management123
Zhang, Fang Fang; Parsons, Susan K
2015-01-01
A high prevalence of obesity and cardiometabolic conditions has been increasingly recognized in childhood cancer survivors. In particular, survivors of pediatric acute lymphoblastic leukemia have been found to be at risk of becoming overweight or obese early in treatment, with increases in weight maintained throughout treatment and beyond. Nutrition plays an important role in the etiology of obesity and cardiometabolic conditions and is among the few modifiable factors that can prevent or delay the early onset of these chronic conditions. However, nutritional intake in childhood cancer survivors has not been adequately examined and the evidence is built on data from small cohorts of survivors. In addition, the long-term impact of cancer diagnosis and treatment on survivors’ nutritional intake as well as how survivors’ nutritional intake is associated with chronic health conditions have not been well quantified in large-scale studies. Promoting family-based healthy lifestyles, preferably at a sensitive window of unhealthy weight gain, is a priority for preventing the early onset of obesity and cardiometabolic conditions in childhood cancer survivors.

Refeeding Syndrome: An Important Complication Following Obesity Surgery.
Chiappetta, Sonja; Stein, Jürgen
2016-01-01
Refeeding syndrome (RFS) is an important and well-known complication in malnourished patients, but the incidence of RFS after obesity surgery is unknown and the awareness of RFS in obese patients as a postsurgical complication must be raised. We present a case of RFS subsequent to biliopancreatic diversion in a morbidly obese patient. A 48-year-old female patient with a BMI of 41.5 kg/m2 was transferred to our hospital due to Wernicke's Encephalopathy in a global malabsorptive syndrome after biliopancreatic diversion. Parenteral nutrition, vitamin supplementation and high-dosed intravenous thiamine supplementation were initiated. After 14 days, the patient started to develop acute respiratory failure, and neurological functions were impaired. Blood values showed significant electrolyte disturbances. RFS was diagnosed and managed according to the NICE guidelines. After 14 days, phosphate levels had returned to normal range, and neurological symptoms were improved. Extreme weight loss following obesity surgery has been shown to be associated with undernutrition. These patients are at high risk for evolving RFS, even though they may still be obese. Awareness of RFS as a postsurgical complication, the identification of patients at risk as well as prevention and correct management should be routinely performed at every bariatric center. © 2016 The Author(s) Published by S.

Disability Discrimination and Obesity: The Big Questions?
Flint, Stuart W; Snook, Jeremé
2015-12-01
Obesity discrimination in employment and recruitment has become a topic of focus for research examination with increasing reports of discrimination by colleagues and managers. Whilst a limited number of legal cases have emerged, disability law is consulted in line with the expectation of anti-discriminatory practices at work. In line with disability law, whether obesity is defined as a disability or not has an impact on the outcome of a court ruling. Ambiguity when defining obesity through either the medical or social model means there are many questions that remain unanswered which might lead to inconsistency in court rulings.

Obesity is a multi-factorial health problem in which genetic factors play an important role. Limited results have been obtained in single-gene studies using either genomic or transcriptomic data. RNA sequencing technology has shown its potential in gaining accurate knowledge about the transcriptome, and may reveal novel genes affecting complex diseases. Integration of genomic and transcriptomic variation (expression quantitative trait loci [eQTL] mapping) has identified causal variants that affect complex diseases. We integrated transcriptomic data from adipose tissue and genomic data from a porcine model to investigate the mechanisms involved in obesity using a systems genetics approach. Using a selective gene expression profiling approach, we selected 36 animals based on a previously created genomic Obesity Index for RNA sequencing of subcutaneous adipose tissue. Differential expression analysis was performed using the Obesity Index as a continuous variable in a linear model. eQTL mapping was then performed to integrate 60 K porcine SNP chip data with the RNA sequencing data. Results were restricted based on genome-wide significant single nucleotide polymorphisms, detected differentially expressed genes, and previously detected co-expressed gene modules. Further data integration was performed by detecting co-expression patterns among eQTLs and integration with protein data. Differential expression analysis of RNA sequencing data revealed 458 differentially expressed genes. The eQTL mapping resulted in 987 cis-eQTLs and 73 trans-eQTLs (false discovery rate < 0.05), of which the cis-eQTLs were associated with metabolic pathways. We reduced the eQTL search space by focusing on differentially expressed and co-expressed genes and disease-associated single nucleotide polymorphisms to detect obesity-related genes and pathways. Building a co-expression network using eQTLs resulted in the detection of a module strongly associated with lipid pathways. Furthermore, we

Objective Whole-body protein metabolism is dysregulated with obesity. Our goal was to determine if activity and expression of major protein degradation pathways are compromised specifically in human skeletal muscle with obesity. Methods We utilized primary Human Skeletal Muscle cell (HSkM) cultures since cellular mechanisms can be studied absent of hormones and contractile activity that could independently influence metabolism. HSkM from 10 lean (BMI ≤ 26.0 kg/m2) and 8 severely obese (BMI ≥ 39.0) women were examined basally and when stimulated to atrophy (serum and amino acid starvation). Results HSkM from obese donors had a lower proportion of type I myosin heavy chain and slower flux through the autophagic/lysosomal pathway. During starvation, flux through the ubiquitin-proteasome system diverged according to obesity status, with a decrease in the lean and an increase in HSkM from obese subjects. HSkMC from the obese also displayed elevated proteasome activity despite no difference in proteasome content. Atrophy-related gene expression and myotube area were similar in myotubes derived from lean and obese individuals under basal and starved conditions. Conclusions Our data indicate that muscle cells of the lean and severely obese have innate differences in management of protein degradation, which may explain their metabolic differences.

Objective To compare the effectiveness and safety of carbohydrate-modified diets with a standard portion-controlled diet among obese children. Study design Obese children (n=102) aged 7-12 years were randomly assigned to a 3-month intervention of low carbohydrate (LC), reduced glycemic load (RGL), or standard portion-controlled (PC) diet, along with weekly dietary counseling and bi-weekly group exercise. Anthropometry, dietary adherence, and clinical measures were evaluated at baseline, 3, 6 and 12 months. Analyses applied intention-to-treat longitudinal mixed models. Results Eighty-five children (83%) completed the 12-month assessment. Daily caloric intake decreased from baseline to all time points for all diet groups (p<0.0001), although LC diet adherence was persistently lower (p<0.0002). At 3 months BMI z-score was lower in all diet groups (LC: -0.27 ± 0.04; RGL: -0.20 ± 0.04; PC: -0.21 ± 0.04; p<0.0001) and maintained at 6 months, with similar results for waist circumference (WC) and percent body fat (%BF). At 12 months, participants in all diet groups had lower BMI z-scores than at baseline (LC: -0.21±0.04; RGL: -0.28±0.04; PC: -0.31±0.04; p<0.0001), and lower %BF, but no reductions in WC were maintained. All diets demonstrated some improved clinical measures. Conclusions Diets with modified carbohydrate intake were as effective as a PC diet for weight management in obese children. However, lower adherence to the LC diet suggests this regimen is more difficult for children to follow, particularly in the long-term. PMID:22381024
The Health Consequences of Obesity in Young Adulthood.
Cheng, Hoi Lun; Medlow, Sharon; Steinbeck, Katharine
2016-03-01
Young adults are gaining weight faster than any age group. This weight gain and the appearance of obesity-related comorbidities often commence in adolescence. Psychosocial distress and mental health issues are common and debilitating, and treatment approaches are likely to be similar to those for adolescents. At the same time, young adults may have physical morbidities which will continue and worsen throughout adulthood, such as hypertension, diabetes and polycystic ovarian syndrome. Health consequences of obesity are challenging to manage in young adults as their symptoms may be minimal, they are less likely to engage with healthcare due to other life priorities and their neurocognitive developmental stage makes therapy adherence difficult. Clinicians who manage young adults with obesity need to be aware of these age-specific challenges, as well as the sexual and reproductive health concerns that are present in this age group.
Childhood obesity: nurses' role in addressing the epidemic.
Rabbitt, Aifric; Coyne, Imelda
Obesity is a significant long-term health problem that is common among children and adolescents in Western countries. Being overweight or obese (extremely overweight) can contribute to type 2 diabetes in childhood and increase the risk of cardiovascular disease in adulthood. Primary prevention of obesity prevents the development of serious secondary complications in adulthood. Nurses can help parents and children by providing nutritional advice and, through weight management programmes, offer strategies for decreasing caloric intake and increasing physical activity. Nurses' actions should always take a whole-family approach because it is challenging for obese children to alter their dietary or physical habits if not supported by their families. Nurses should work with all members of the multidisciplinary team in addressing childhood obesity as it is a major health issue with long-term mobidities.

The number of overweight and obese children and adolescents has increased worldwide. Obese children and adolescents need counseling interventions, including technology-based methods, to help them manage their weight by changing their lifestyles. To describe technology-based counseling interventions in supporting obese or overweight children and adolescents to change their weight/lifestyle. Descriptive systematic literature review. A literature search was conducted using Cinahl, Medline, PsycINFO, and Medic databases in September 2010 and updated in January 2015. Predefined inclusion criteria were used for the search. After a quality assessment, 28 studies were included in the data extraction. No statistically significant difference in BMI was detected between the intervention and control groups. However, in some studies, it was found that BMI decreases and there were statistically significant differences in fruit and vegetable consumption. In two studies, differences in physical activity were detected between the intervention and control groups, but in eight studies, the difference was not significant. Goal setting and feedback on progress support physical activity and changes in diet. This study identifies available technology interventions for obese or overweight children and adolescents. It seems that using technology-based counseling intervention may encourage obese and overweight children and adolescents to pursue a healthier lifestyle.
The Physiologic Effects of Pneumoperitoneum in the Morbidly Obese
Nguyen, Ninh T.; Wolfe, Bruce M.

Objective: To review the physiologic effects of carbon dioxide (CO2) pneumoperitoneum in the morbidly obese. Summary Background Data: The number of laparoscopic bariatric operations performed in the United States has increased dramatically over the past several years. Laparoscopic bariatric surgery requires abdominal insufflation with CO2 and an increase in the intraabdominal pressure up to 15 mm Hg. Many studies have demonstrated the adverse consequences of pneumoperitoneum; however, few studies have examined the physiologic effects of pneumoperitoneum in the morbidly obese. Methods: A MEDLINE search from 1994 to 2003 was performed using the key words morbid obesity, laparoscopy, bariatric surgery, pneumoperitoneum, and gastric bypass. The authors reviewed papers evaluating the physiologic effects of pneumoperitoneum in morbidly obese subjects undergoing laparoscopy. The topics examined included alteration in acid-base balance, hemodynamics, femoral venous flow, and hepatic, renal, and cardiorespiratory function. Results: Physiologically, morbidly obese patients have a higher intraabdominal pressure at 2 to 3 times that of nonobese patients. The adverse consequences of pneumoperitoneum in morbidly obese patients are similar to those observed in nonobese patients. Laparoscopy in the obese can lead to systemic absorption of CO2 and increased requirements for CO2 elimination. The increased intraabdominal pressure enhances venous stasis, reduces intraoperative portal venous blood flow, decreases intraoperative urinary output, lowers respiratory compliance, increases airway pressure, and impairs cardiac function. Intraoperative management to minimize the adverse changes include appropriate ventilatory adjustments to avoid hypercapnia and acidosis, the use of sequential compression devices to minimizes venous stasis, and optimize intravascular volume to minimize the effects of increased intraabdominal pressure on renal and cardiac function. Conclusions: Morbidly obese

Continuous glucose monitoring system (CGMS) can measure glucose levels at 5-minute intervals over a few days, and may be used to detect hypoglycemia, guide insulin therapy, and control glucose levels. This study was undertaken to assess the glucose metabolism disorder by CGMS in obese children. Eighty-four obese children were studied. Interstitial fluid (ISF) glucose levels were measured by CGMS for 24 hours covering the time for oral glucose tolerance test (OGTT). Impaired glucose tolerance (IGT), impaired fasting glucose (IFG), type 2 diabetic mellitus (T2DM) and hypoglycemia were assessed by CGMS. Five children failed to complete CGMS test. The glucose levels in ISF measured by CGMS were highly correlated with those in capillary samples (r=0.775, P<0.001). However, the correlation between ISF and capillary glucose levels was lower during the first hour than that in the later time period (r=0.722 vs r=0.830), and the ISF glucose levels in 69.62% of children were higher than baseline levels in the initial 1-3 hours. In 79 obese children who finished the CGMS, 2 children had IFG, 2 had IGT, 3 had IFG + IGT, and 2 had T2DM. Nocturnal hypoglycemia was noted during the overnight fasting in 11 children (13.92%). Our data suggest that glucose metabolism disorder including hyperglycemia and hypoglycemia is very common in obese children. Further studies are required to improve the precision of the CGMS in children.

Information on risks associated with obesity during infancy specific to Hispanic children is scarce. This retrospective medical record review describes characteristics and parenting practices of Hispanic children age <2 years referred for obesity care at a tertiary hospital over a 6-year period. Data on 29 Hispanic children collected from parent-completed assessment forms and clinician documentation were analyzed. Children were of mean age 16.2 ± 4.9 months; body mass index z scores ranged from 1.5 to 9.4 (mean 4.5 ± 1.7); 45% were male; 97% received public insurance; 38% were breastfed ≥6 months; and 93% had a parent who was overweight or obese. Parenting practices included bottle feeding in bed (50%), regularly drinking sweetened beverages (33%), ≥2 hours of screen time (60%), and having a TV in child’s bedroom (55%). Better understanding of factors that contribute to the development of rapid weight gain of Hispanic children can inform future clinical and public health interventions. PMID:29147676

The aim of this communication is to provide some evidence linking the overweight/obesity and their impacts on different dimensions of health. We reviewed the related studies published from 1990 up till now through PubMed Central/Medline, which provide evidence linking obesity with health related issues. It is a risk factor for metabolic disorders and leads to serious health consequences for individuals and burden for the health care system as a whole. Literature search showed that it is related to at least 18 co-morbidities which are attributable to overweight and obesity. Moreover obese individuals more often suffer from significant joint pains, disorders and it also has social as well as psychological impairments. It is high time that countries facing the problems of obesity initiate some intervention measures to monitor and control this growing epidemic. PMID:25878654
Osteoarthritis, obesity and weight loss: evidence, hypotheses and horizons – a scoping review
Bliddal, H; Leeds, A R; Christensen, R
2014-01-01
Obesity is widely acknowledged as a risk factor for both the incidence and progression of osteoarthritis, and has a negative influence on outcomes. Loss of at least 10& of body weight, coupled with exercise, is recognized as a cornerstone in the management of obese patients with osteoarthritis, and can lead to significant improvement in symptoms, pain relief, physical function and health-related quality of life. However, questions still remain surrounding optimal management. Given the significant health, social and economic burden of osteoarthritis, especially in obese patients, it is imperative to advance our knowledge of osteoarthritis and obesity, and apply this to improving care and outcomes. This paper overviews what is already known about osteoarthritis and obesity, discusses current key challenges and ongoing hypotheses arising from research in these areas, and finally, postulates what the future may hold in terms of new horizons for obese patients with osteoarthritis.

Behavioral Variables Associated with Obesity in Police Officers
CAN, S. Hakan; HENDY, Helen M.
2014-01-01
Past research has documented that non-behavioral variables (such as long work hours, exposure to police stressors) are associated with obesity risk in police officers, but limited research has examined behavioral variables that might be targeted by Employee Assistance Programs for police weight management. The present study compared non-obese and obese officers for behavioral variables found associated with obesity in other adult samples: physical activity (cardiovascular, strength-training, stretching), sleep duration, and consumption of alcohol, fruit and vegetables, and snack foods. Participants included 172 male police officers who completed questionnaires to report height and weight, used to calculate body mass index (BMI = kg/m2) and to divide them into “non-obese” and “obese” groups. They also reported the above behaviors and six non-behavioral variables found associated with obesity risk: age, health problems, family support, police work hours, police stressors, police support. ANCOVAs compared each behavioral variable across obesity status (non-obese, obese), with the six non-behavioral variables used as covariates. Results revealed that cardiovascular and strength-training physical activity were the only behavioral variables that differed significantly between non-obese and obese police officers. The use of self-reported height and weight values may provide Employee Assistance Program with improved cost, time, and officer participation. PMID:24694574

The purpose of this study was to investigate whether the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene and 3123C/A polymorphism of the angiotensin II type 2 receptor (AT(2)R) gene affect blood pressure and other obesity-related metabolic changes in response to low-energy diets using meal replacement shakes for weight loss. Clinical, metabolic, and biochemical profiles were measured before and after a 2-mo intervention in 32 obese women (age 49.9 ± 8.4 [SD] y; BMI 28.4 ± 3.3 kg/m²) restricted to 1200 kcal/d (5021 kJ/d). The polymorphisms were determined with an intercalater-mediated FRET probe assay system. Although weight loss and nutrient intake levels did not differ among the genotypes, the reduction in body fat after weight loss was significantly less in the ACE deletion/deletion (D/D) genotype than insertion/insertion (I/I) plus I/D genotype (-2.25 ± 1.40% versus -0.80 ± 1.57%, P < 0.05). The AT₂R A/A group had significantly less improved levels of systolic blood pressure (-7.23 ± 8.50 versus 2.50 ± 12.6 mmHg, P < 0.05), low-density lipoprotein-cholesterol (-0.36 ± 0.29 versus -0.09 ± 0.25 mmol/L, P < 0.05), carbohydrate (-54.4 ± 27.2 versus -31.8 ± 16.3 mg/min, P < 0.05) and fat oxidation (8.31 ± 11.86 versus 0.05 ± 9.99 mg/min, P < 0.05) than the C/C plus C/A genotypes. The present findings suggest that the homozygous form of the ACE gene may hinder the improvement of body fat and that the homozygous form of the AT₂R gene may make improving systolic blood pressure and some obesity-related metabolic parameters through a dietary intervention difficult among obese women.

To investigate factors that may be associated with urinary incontinence (UI) in abdominal obese and non-obese adult males. Data were analyzed for 2671 men (≥40 years of age) who participated in the National Health and Nutrition Examination Survey (2005-2008). We define abdominal obesity as a waist circumference >102 cm. Men with Incontinence Severity Index ≥3 were defined as having UI. Logistic regression analyses were used to identify factors associated with stress and urge UI. Multivariate analysis found that in abdominal obese men, stress UI was associated with enlarged prostate (odds ratio [OR] = 2.20, 95% confidence interval [CI]: 1.16-4.16), chronic respiratory tract disease (OR = 2.78, 95% CI: 1.55-4.97), and major depression (OR = 4.79, 95% CI: 1.79-12.84). In non-obese men, arthritis was associated with stress UI (odds ratio = 3.37, 95% CI: 1.06-10.73). Urge UI in abdominally obese men was associated with age ≥65 years (OR = 1.67, 95% CI: 1.05-2.67), being non-Hispanic black (OR = 1.63, 95% CI: 1.06-2.52), and with enlarged prostate (OR = 2.30, 95% CI: 1.54-3.40), arthritis (OR = 1.39, 95% CI: 1.03-1.88), and major depression (OR = 2.96, 95% CI: 1.89-4.64). Urge UI in non-obese men was associated with current smoking (OR = 1.79, 95% CI: 1.01-3.17), major depression (OR = 2.60, 95% CI: 1.33-5.09) and vitamin D deficiency (OR = 1.61, 95% CI: 1.01-2.59). Factors associated with urinary incontinence varied with abdominal obesity status and type of UI. The findings identify important contributors to urinary incontinence that clinicians should consider to help manage and effectively treat the condition.
Obesity and type 1 diabetes mellitus management.

Patients with type 1 diabetes mellitus (T1DM) traditionally had a low body mass index and microangiopathic complications were common. The Diabetes Control and Complications Trial, published in 1993, demonstrated that therapy aimed at maintaining HbA1c levels as close to normal as feasible reduced the incidence of microangiopathy. Since then, the use of intensive insulin therapy to optimise metabolic control became generalised, with two main side effects: a higher rate of severe hypoglycaemia and increased weight gain. Approximately 50% of patients with T1DM are currently obese or overweight, which reduces or nullifies the benefits of good metabolic control, and which has other negative consequences; therefore, strategies to achieve weight control in patients with T1DM are necessary. At present, treatment with GLP-1 and SGLT-2 inhibitors has yielded promising short-term results that need to be confirmed in studies with larger numbers of patients and long-term follow-up. It is possible that, in coming years, the applicability of bariatric surgery in obese patients with T1DM will be similar to that of the general population or T2DM.

An obesity paradox, wherein obese patients have lower mortality, has been described in cardiopulmonary diseases, including pulmonary arterial hypertension (PAH). Our objective was to determine whether obesity and body mass index (BMI) are associated with mortality in patients with PAH. We assessed incident patients with idiopathic, drug-induced, and heritable PAH from the French PAH Registry. Cox regression and Kaplan-Meier analysis were used to assess the association between BMI and obesity with all-cause mortality. Of 1255 patients included, 30% were obese. A higher proportion of females (65.1% vs 53.4%, p<0.01), drug-induced PAH (28.9% vs 9.2%, p<0.01), systemic hypertension, diabetes, and hypothyroidism were present in the obese group. More obese patients were in New York Heart Association class III (66.4% vs. 57.1%), fewer were class IV (11.8% vs 16.9%) (p<0.01), and 6-minute walk distance was lower (276±121 vs 324±146, p<0.01). Right atrial pressure, pulmonary wedge pressure and cardiac index were higher while pulmonary vascular resistance was lower in obese patients. Neither BMI (HR 0.99, 95%CI 0.97-1.01, p=0.41) nor obesity (HR 1.0, 95%CI 0.99-1.01, p=0.46) were associated with mortality in multivariable analyses. There was a significant interaction between age and obesity such that mortality increased among morbidly obese patients under 65 years old (HR 3.01, 95%CI 1.56-5.79, p=0.001). Obesity was not associated with mortality in the overall population, but there was an age-obesity interaction with increased mortality among young morbidly obese patients. These results have implications for active weight management in younger morbidly obese patients who are otherwise candidates for lung transplantation. Copyright © 2018. Published by Elsevier Inc.

The obesity epidemic has spared no age group, even young infants. Most childhood obesity is incident by the age of 5 years, making prevention in preschool years a priority. To examine 2-year changes in age- and sex-specific BMI z-scores and obesity-related behaviours among 441 of the 475 originally recruited participants in High Five for Kids, a cluster randomized controlled trial in 10 paediatric practices. The intervention included a more intensive 1-year intervention period (four in-person visits and two phone calls) followed by a less intensive 1-year maintenance period (two in-person visits) among children who were overweight or obese and age 2-6 years at enrolment. The five intervention practices restructured care to manage these children including motivational interviewing and educational modules targeting television viewing and intakes of fast food and sugar-sweetened beverages. After 2 years, compared with usual care, intervention participants had similar changes in BMI z-scores (-0.04 units; 95% CI -0.14, 0.06), television viewing (-0.20 h/d; -0.49 to 0.09) and intakes of fast food (-0.09 servings/week; -0.34 to 0.17) and sugar-sweetened beverages (-0.26 servings/day; -0.67 to 0.14). High Five for Kids, a primarily clinical-based intervention, did not affect BMI z-scores or obesity-related behaviours after 2 years. © 2016 World Obesity Federation.

To apply the Theory of Planned Behaviour to examine the relationship between the constructs of background factors and beliefs towards using policy, systems and environmental (PSE) strategies and reported use of PSE strategies to prevent obesity by a group of professional nutrition educators. Cross-sectional study using self-reported survey. Cooperative Extension in New York, USA. Nutrition educators (n 58); survey response rate 100 %. Nutrition educators' reported use of PSE strategies to prevent obesity were positively associated with background factors of their community networking and number of staff they managed, their belief of other people's expectations of them to make PSE changes and the belief that their communities were ready to use PSE strategies; and negatively associated with their belief that individual-level factors contributed to obesity. The relationships among these variables were complicated and their use of PSE strategies occurred only when they utilized their professional networks at a moderately high level (above mean of 5·3 on a scale of 1-7), given that their community was also ready to use PSE strategies. Nutrition educators' use of PSE strategies depends on several internal and external factors. Community networking needs to be emphasized as one of the most significant factors contributing to nutrition educators' work in this area. Organizational and community support should be in place in order to facilitate nutrition educators' effective use of PSE strategies.

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.
Genetics of Oxidative Stress in Obesity
Rupérez, Azahara I.; Gil, Angel; Aguilera, Concepción M.
2014-01-01
Obesity is a multifactorial disease characterized by the excessive accumulation of fat in adipose tissue and peripheral organs. Its derived metabolic complications are mediated by the associated oxidative stress, inflammation and hypoxia. Oxidative stress is due to the excessive production of reactive oxygen species or diminished antioxidant defenses. Genetic variants, such as single nucleotide polymorphisms in antioxidant defense system genes, could alter the efficacy of these enzymes and, ultimately, the risk of obesity; thus, studies investigating the role of genetic variations in genes related to oxidative stress could be useful for better understanding the etiology of obesity and its metabolic complications. The lack of existing literature reviews in this field encouraged us to gather the findings from studies focusing on the impact of single nucleotide polymorphisms in antioxidant enzymes, oxidative stress-producing systems and transcription factor genes concerning their association with obesity risk and its phenotypes. In the future, the characterization of these single nucleotide polymorphisms (SNPs) in obese patients could contribute to the development of controlled antioxidant therapies potentially beneficial for the treatment of obesity-derived metabolic complications.

Mobile-Health (mHealth) is the fastest-developing eHealth sector, with over 100 000 health applications (apps) currently available. Overweight/obesity is a problem of wide public concern that is potentially treatable/preventable through mHealth. This study describes the current weight-management app-market. Five app stores (Apple, Google, Amazon, Windows and Blackberry) in UK, US, Russia, Japan and Germany, Italy, France, China, Australia and Canada were searched for keywords: 'weight', 'calorie', 'weight-loss', 'slimming', 'diet', 'dietitian' and 'overweight' in January/February 2016 using App-Annie software. The 10 most downloaded apps in the lifetime of an app were recorded. Developers' lists and the app descriptions were searched to identify any professional input with keywords 'professional', 'dietitian' and 'nutritionist'. A total of 28 905 relevant apps were identified as follows: Apple iTunes=8559 (4634, 54% paid), Google Play=1762 (597, 33.9% paid), Amazon App=13569 (4821, 35.5% paid), Windows=2419 (819, 17% paid) and Blackberry=2596 (940, 36% paid). The 28 905 identified apps focused mainly on physical activity (34%), diet (31%), and recording/monitoring of exercise, calorie intake and body weight (23%). Only 17 apps (0.05%) were developed with identifiable professional input. Apps on weight management are widely available and very popular but currently lack professional content expertise. Encouraging app development based on evidence-based online approaches would assure content quality, allowing healthcare professionals to recommend their use.

This study explored current physiotherapy practice trends for management of children who are overweight or obese. The professional needs of physiotherapists working with this population were also assessed, including the perceived need for physiotherapy clinical guidelines for prevention and management of children with obesity. A cross-sectional survey design was used, with questionnaires purposefully distributed through 13 key physiotherapy services throughout Australia. Snowball sampling resulted in completed questionnaires from 64 physiotherapists who provided services to children. Half (n=33, 52%) of respondents provided services specifically to overweight or obese children. Of those providing services, one-quarter had prior training specific to working with this population. Most used multi-disciplinary models (n=16, 76%) and provided under 5h of obesity-related services each week (n=29, 88%). Half (n=16, 49%) used body mass index as an outcome measure but more (n=25, 76%) used bodyweight. Only 14 (42%) assessed motor skills. The majority of respondents (n=57, 89%) indicated a need for physiotherapy guidelines to best manage overweight and obese children. Professional development priorities included: 'Educating children and families', 'Assessment methods' and 'Exercise prescription' for overweight and obese children. This data provides workforce intelligence to guide future professional training and inform development of clinical guidelines for physiotherapists in prevention and management of children with obesity and related chronic disease.
Managing hybrid marketing systems.
Moriarty, R T; Moran, U
1990-01-01
As competition increases and costs become critical, companies that once went to market only one way are adding new channels and using new methods - creating hybrid marketing systems. These hybrid marketing systems hold the promise of greater coverage and reduced costs. But they are also hard to manage; they inevitably raise questions of conflict and control: conflict because marketing units compete for customers; control because new indirect channels are less subject to management authority. Hard as they are to manage, however, hybrid marketing systems promise to become the dominant design, replacing the "purebred" channel strategy in all kinds of businesses. The trick to managing the hybrid is to analyze tasks and channels within and across a marketing system. A map - the hybrid grid - can help managers make sense of their hybrid system. What the chart reveals is that channels are not the basic building blocks of a marketing system; marketing tasks are. The hybrid grid forces managers to consider various combinations of channels and tasks that will optimize both cost and coverage. Managing conflict is also an important element of a successful hybrid system. Managers should first acknowledge the inevitability of conflict. Then they should move to bound it by creating guidelines that spell out which customers to serve through which methods. Finally, a marketing and sales productivity (MSP) system, consisting of a central marketing database, can act as the central nervous system of a hybrid marketing system, helping managers create customized channels and service for specific customer segments.

Obesity has been linked with a proinflammatory state and the development of inflammatory diseases. Data on the clinical course and treatment of obese patients with inflammatory bowel disease (IBD) are limited. We used an institutional IBD registry to investigate the impact of obesity on IBD severity and treatment. This was a retrospective analysis of prospectively collected data for 3 years (2009-2011). Patients with IBD were categorized by body mass index (BMI). IBD-related quality of life, biochemical markers of inflammation, comorbidities, health care utilization, and treatment were characterized. Obesity was defined as a BMI ≥30 (type I: 30-34.9, type II: 35-39.9, and type III ≥40). Among 1494 patients with IBD, 71.9% were above their ideal BMI and 31.5% were obese. Obesity was more common in ulcerative colitis compared with patients with Crohn's disease (P = 0.04). Obese class II and class III patients were predominantly female. Obesity in IBD was associated with female gender (P < 0.0001), diabetes mellitus (P < 0.001), hypertension (P < 0.001), hyperlipidemia (P < 0.001), poor quality of life (P < 0.0001), and increased rates of C-reactive protein elevation (P = 0.008). In logistic regression analysis, quality of life and C-reactive protein elevation were not independently correlated with obesity. There was no association between increasing BMI and annual prednisone use, emergency department visits, hospitalization, and surgery. Obesity was associated with lower milligrams per kilogram doses of purine analogs and biologics. Obesity in IBD is not associated with increased health care utilization and IBD-related surgeries. Optimal regimens for drug dosing in obese patients with IBD have yet to be defined.

This study aims to compare three body mass index (BMI)-based classification systems of childhood obesity: the French, the International Obesity Task Force (IOTF) and the World Health Organization (WHO) references. The study involved 1382 schoolchildren, recruited from the Lille Academic District in France in May 2009 aged 8.4±1.7 years (4.0-12.0 years). Their mean height and body mass were 131.5±10.9cm and 30.7±9.2kg, respectively, resulting in a BMI of 17.4±3.2kg/m(2). The weight status was defined according to the three systems considered in this study. The agreement between these references was tested using the Cohen's kappa coefficient. The prevalence of overweight was higher with the WHO references (20.0%) in comparison with the French references (13.8%; P<0.0001) and the IOTF (16.2%; P≤0.01). A similar result was found with obesity (WHO: 11.6% vs. IOTF: 6.7%; or French references: 6.7%; P<0.0001). Agreement between the three references ranged from "moderate" to "perfect" (0.43≤κ≤1.00; P<0.0001). Kappa coefficients were higher when the three references were used to classify children as obese (0.63≤κ≤1.00; P<0.0001) as compared to classification in the overweight (obesity excluded) category (0.43≤κ≤0.94; P<0.0001). When sex and age categories (4-6 years vs. 7-12 years) were considered to define the overweight status, the lowest kappa coefficient was found between the French and WHO references in boys aged 7-12 years (κ=0.28; P<0.0001), and the highest one in girls aged 7-12 years between the French references and IOTF (κ=0.97; P<0.0001). As for obesity, agreement between the three references ranged from 0.60 to 1.00 (P<0.0001), with the lowest values obtained in the comparison of the WHO references against French references or IOTF among boys aged 7-12 years (κ=0.60; P<0.0001). Overall, the WHO references yield an overestimation in overweight and/or obesity within this sample of schoolchildren as compared to the French references and the

In recent years, the incidence of childhood obesity in Europe, and Spain in particular, has increased dramatically. Bariatric surgery could play a major role in treating of adolescents with severe obesity. However, no specific guidelines for bariatric surgery currently exist in Spain. The Board of the Spanish Society for Obesity Surgery and Metabolic Diseases (SECO) proposed a study of childhood obesity by using the Delphi method. This prospective study involved 60 experts from nine national societies. Each society leader recruited experts from their society in obesity-related fields. Two online questionnaires were taken, and consensus on guidelines for various obesity treatments was reached according to the percentage of answers in favor or against inclusion of a given guideline. Based on these results, preoperative, surgical management and follow-up of childhood obesity management among others were analyzed. The survey results indicated significant concern among all societies regarding obesity. There was strong consensus with regard to adolescents and obesity, medical treatment, dietary recommendations, environmental and social factors, and goals for adolescents with obesity. Consensus on the use of intragastric balloons and other techniques was not reached. However, biliopancreatic diversion was rejected as a primary treatment, and mandatory psychological/psychiatric assessment was agreed upon. Inclusion criteria accepted were similar to those for adults with the exception of surgery in those with a body mass index <40. Spanish obesity-related societies are aware of the societal problem of childhood obesity. Multisociety development of national approaches may arise from consensus-building studies among specialists.
A complications-based clinical staging of obesity to guide treatment modality and intensity
Daniel, Sunil; Soleymani, Taraneh; Garvey, William T.
2014-01-01
Purpose of review The current medical model for obesity management is BMI-centric because BMI is the predominant measure used to gauge disease severity, as well as indications for various treatment modalities. Recent advancements in therapy and understanding of the relationship between BMI and obesity-related complications call for a re-examination of this approach. Recent findings Advancements in treatment, including the recent approval of two new weight loss medications in the USA, have enabled development of new medical models for management of obesity. On the basis of accumulating data demonstrating the benefits of weight loss regarding multiple obesity-related complications (e.g., diabetes prevention, type 2 diabetes mellitus, cardiovascular disease risk, nonalcoholic steatohepatitis, sleep apnea), a complications-centric model is proposed that employs weight loss as a tool to treat and prevent obesity comorbidities. This model assures that the aggressiveness of therapy is commensurate with disease severity, and that therapy is directed at those obese patients who will benefit most from weight loss therapy. The treatment algorithm is comprehensive in addressing complications and quantitative when possible in the staging of risk or disease severity. Summary A complications-centric approach to obesity management identifies patients who will benefit most from weight loss, and optimizes patient outcomes, benefit/risk ratio, and the cost–effectiveness of interventions.

Genetics of obesity: can an old dog teach us new tricks?
Yeo, Giles S H
2017-05-01
At one level, obesity is clearly a problem of simple physics, a result of eating too much and not expending enough energy. The more complex question, however, is why do some people eat more than others? Studies of human and mouse genetics over the past two decades have uncovered a number of pathways within the brain that play a key role in the control of food intake. A prime example is the leptin-melanocortin pathway, which we now know greatly contributes to mammalian appetitive behaviour. However, genetic disruption of this pathway remains rare and does not represent the major burden of the disease that is carried by those of us with 'common obesity'. In recent years, genome-wide association studies have revealed more than 100 different candidate genes linked to BMI, with most (including many components of the melanocortin pathway) acting in the central nervous system and influencing food intake. So while severe disruption of the melanocortin pathway results in severe obesity, subtle variations in these genes influence where you might sit in the normal distribution of BMI. As we now enter this 'post-genomics' world, can this new information influence our treatment and management of obese patients?
Is the calorie concept a real solution to the obesity epidemic?
Camacho, Salvador; Ruppel, Andreas
2017-01-01
ABSTRACT Background: The obesity epidemic has been growing steadily across the whole world, and so far not a single country has been able to reverse it. The cause of obesity is stated by the World Health Organization as an energy imbalance between calories consumed and calories expended. However, growing evidence suggests that the calorie imbalance concept may not be sufficient to manage and reverse the obesity epidemic. Objective: To discuss the use of the calorie imbalance concept and its elements as a tool for weight management as well as its possible negative consequences and implications for public health, with the aim to point toward the need of an updated concept for causes of obesity. This update should guide public health interventions more efficiently to limit obesity by preventing weight gain or promoting weight loss. Methods: This is a literature reviews based on a semi-structured approach to determine the material to be examined. Results: After revisiting general facts about fat generation and accumulation, we propose an updated concept for the causes of obesity including diet composition and hormonal regulation of fat metabolism. Conclusions: We discuss how this updated concept could benefit the overall efficiency of strategies against obesity, and hypothesize how potential resistance to adopting this new view could be lowered.

The international management standards allow their integrated approach, thereby combining aspects of particular importance to the activity of any organization, from the quality management systems or the environmental management of the information security systems or the business continuity management systems. Although there is no national or international regulation, nor a defined standard for the Integrated Management System, the need to implement an integrated system occurs within the organization, which feels the opportunity to integrate the management components into a cohesive system, in agreement with the purpose and mission publicly stated. The issues relating to information security in the organization, from the perspective of the management system, raise serious questions to any organization in the current context of electronic information, reason for which we consider not only appropriate but necessary to promote and implement an Integrated Management System Quality - Environment - Health and Operational Security - Information Security

Obesity is associated with larger tumors, shorter time to PSA failure, and higher Gleason scores. However, the mechanism(s) by which obesity promotes aggressive prostate cancer remains unknown. We hypothesize that circulating factors related to obesity promote prostate cancer progression by modulating components of the metastatic cascade. Male C57BL/6 mice (6 weeks) were fed an ad libitum diet-induced obesity (60% fat) or control diet (10% fat) for 12 weeks. Serum was collected, metabolic and inflammatory proteins were measured by an antibody array. Sera were used to measure, in vitro, characteristics of a metastatic phenotype. Comparable to obese men, obese sera contained higher levels or leptin, vascular endothelial growth factor, PAI-1, interleukin-6 (IL-6) and lower levels of testosterone. In prostate cells, serum was used to assess: proliferation, invasion, migration, epithelial-mesenchymal-transition (EMT) and matrix metalloproteinase (MMP) activity. LNCaP and PacMetUT1 cells exposed to obese sera increased proliferation, whereas PrEC and DU145 were unaffected. LNCaP, PacMetUT1 and DU145 cancer cells exposed to obese sera resulted in increased invasion, migration and MMP-9 activity. Prostate cancer cells exposed to obese sera showed increased vimentin, dispersion of e-cadherin and β-catenin from the plasma membrane. We report, prostate cancer cells exposed to sera from obese mice increases proliferation, invasion, migration, MMP activity and induces changes in proteins critical for EMT.

Obesity recognition in primary care is important to address the epidemic. We aimed to evaluate primary care clinician-reported documentation, management practices, beliefs and attitudes toward obesity compared to body mass index (BMI) calculation, obesity prevalence and actual documentation of obesity as an active problem in electronic health record in a rural academic center. Our target population for previously validated clinician survey was 56 primary care providers working at 3 sites. We used calendar year 2012 data for assessment of baseline system performance for metrics of documentation of BMI in primary care visits, and proportion of visits in patients with obesity with obesity as a problem. Standard statistical methods assessed the data. Survey response rate was 91%. Average age of respondents was 48.9 years and 62.7% were females. 72.5% clinicians reported having normal BMI. The majority of clinicians reported regularly documenting obesity as an active problem, and utilized motivational interviewing and basic good nutrition and healthy exercise. Clinicians identified lack of discipline and exercise time, access to unhealthy food and psychosocial issues as major barriers. Most denied disliking weight loss discussion or patients taking up too much time. In 21,945 clinic visits and 11,208 annual preventive care visits in calendar year 2012, BMI was calculated in 93% visits but obesity documentation as an active problem only 27% of patients meeting BMI criteria for obesity. Despite high clinician-reported documentation of obesity as an active problem, actual obesity documentation rates remained low in a rural academic medical center.

Adolescent obesity is a chronic disease that is impacted from each patient's biopsychosocial milieu. Successfully treating pediatric obesity requires long-term, innovative, systematic involvement to facilitate patient and family engagement and change. Extensive chart review was done for three obese adolescents who underwent comprehensive weight management in an adolescent clinic seen within the past 5 years. The charts were reviewed starting from the time of initial contact through the last visit in the clinic. The patients are no longer receiving care within the clinic. The patients presented with BMI>99th percentile, family history of obesity, severe psychosocial stressors, and multiple obesity-related comorbidities. Their treatment involved comprehensive multidisciplinary intervention in an adolescent weight management clinic within a tertiary care center. In addition to rigorous support through frequent office visits, these patients all eventually required temporary, alternative living arrangements to successfully implement recommendations. One patient resided with another family member; two went to inpatient weight management program care for 2-3 months. All subjects successfully lost weight when away from their primary residence, and they demonstrated improvement or resolution of comorbidities. This case series of three adolescents who underwent comprehensive obesity evaluation and treatment demonstrates multidisciplinary care across interconnected treatment programs and active engagement of family. Those who maintained successful weight loss reduced sedentary time, demonstrated family support (e.g., key members attending follow-up visits), and altered their living environment and were committed to their own health goals.
Obesity and Asthma: A Missing Link.

Obesity and asthma are two chronic conditions that affect millions of people. Genetic and lifestyle factors such as diet, physical activity, and early exposure to micro-organisms are important factors that may contribute to the escalating prevalence of both conditions. The prevalence of asthma is higher in obese individuals. Recently, two major phenotypes of asthma with obesity have been described: one phenotype of early-onset asthma that is aggravated by obesity, and a second phenotype of later-onset asthma that predominantly affects women. Systemic inflammation and mechanical effect, both due to the expansion of the adipose tissue, have been proposed as the main reasons for the association between obesity and asthma. However, the mechanisms involved are not yet fully understood. Moreover, it has also been suggested that insulin resistance syndrome can have a role in the association between these conditions. The intestinal microbiota is an important factor in the development of the immune system, and can be considered a link between obesity and asthma. In the obese state, higher lipopolysaccharide (LPS) serum levels as a consequence of a microbiota dysbiosis have been found. In addition, changes in microbiota composition result in a modification of carbohydrate fermentation capacity, therefore modifying short chain fatty acid (SCFA) levels. The main objective of this review is to summarize the principal findings that link obesity and asthma.
