Obesity history, physical exam, laboratory, body composition, and energy expenditure: An Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) 2022.

Background: This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) on History, Physical Exam, Body Composition and Energy Expenditure is intended to provide clinicians an overview of the clinical and diagnostic evaluation of patients with pre-obesity/obesity. Methods: The scientific information for this CPS is based upon published scientific citations, clinical perspectives of OMA authors, and peer review by the Obesity Medicine Association leadership. Results: This CPS outlines important components of medical, dietary, and physical activity history as well as physical exams, with a focus on specific aspects unique to managing patients with pre-obesity or obesity. Patients with pre-obesity/obesity benefit from the same preventive care and general laboratory testing as those without an increase in body fat. In addition, patients with pre-obesity/obesity may benefit from adiposity-specific diagnostic testing - both generally and individually - according to patient presentation and clinical judgment. Body composition testing, such as dual energy x-ray absorptiometry, bioelectrical impedance, and other measures, each have their own advantages and disadvantages. Some patients in clinical research, and perhaps even clinical practice, may benefit from an assessment of energy expenditure. This can be achieved by several methods including direct calorimetry, indirect calorimetry, doubly labeled water, or estimated by equations. Finally, a unifying theme regarding the etiology of pre-obesity/obesity and effectiveness of treatments of obesity centers on the role of biologic and behavior efficiencies and inefficiencies, with efficiencies more often associated with increases in fat mass and inefficiencies more often associated with decreases in fat mass. Conclusion: The Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) on History, Physical Exam, Body Composition and Energy Expenditure is one of a series of OMA CPSs designed to assist clinicians in the care of patients with the disease of pre-obesity/obesity.

Conclusions: This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) on 30 common obesity myths, misunderstandings, and/or oversimplifications is one of a series of OMA CPSs designed to assist clinicians in the care of patients with the disease of obesity. Knowledge of the underlying science may assist the obesity medicine clinician improve the care of patients with obesity.

Nutrition and physical activity: An Obesity Medicine Association (OMA) Clinical Practice Statement 2022.

Background: This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) on Nutrition and Physical Activity provides clinicians an overview of nutrition and physical activity principles applicable to the care of patients with increased body fat, especially those with adverse fat mass and adiposopathic metabolic consequences. Methods: The scientific information and clinical guidance is based upon referenced evidence and derived from the clinical perspectives of the authors. Results: This OMA CPS on Nutrition and Physical Activity provides basic clinical information regarding carbohydrates, proteins, fats (including trans fats, saturated fats, polyunsaturated fats, and monounsaturated fats), general principles of healthful nutrition, nutritional factors associated with improved health outcomes, and food labels. Included are the clinical implications of isocaloric substitution of refined carbohydrates with saturated fats and vice-versa, as well as definitions of low-calorie, very low-calorie, carbohydrate-restricted, and fat-restricted dietary intakes. Specific dietary plans discussed include carbohydrate-restricted diets, fat-restricted diets, very low-calorie diets, the Mediterranean diet, Therapeutic Lifestyle diet, Dietary Approaches to Stop Hypertension (DASH), ketogenic (modified Atkins) diet, Ornish diet, Paleo diet, vegetarian or vegan diet (whole food/plant-based), intermittent fasting/time restricted feeding, and commercial diet programs. This clinical practice statement also examines the health benefits of physical activity and provides practical pre-exercise medical evaluation guidance as well as suggestions regarding types and recommended amounts of dynamic (aerobic) training, resistance (anaerobic) training, leisure time physical activity, and non-exercise activity thermogenesis (NEAT). Additional guidance is provided regarding muscle physiology, exercise prescription, metabolic equivalent tasks (METS), and methods to track physical activity progress. Conclusion: This Obesity Medicine Association Clinical Practice Statement on Nutrition and Physical Activity provides clinicians an overview of nutrition and physical activity. Implementation of appropriate nutrition and physical activity in patients with pre-obesity and/or obesity may improve the health of patients, especially those with adverse fat mass and adiposopathic metabolic consequences.

Obesity and Men's Health.

The health outcomes of men are significantly worse, when compared with their female counterparts, for the top 15 leading causes of death nationwide. At this time, men are not actively engaged in the health care system, creating a challenge for those managing patients in the clinical setting. The premature morbidity and mortality of men financially burdens the health care system and places a financial strain in secondary and tertiary preventive care that is simply not sustainable. Obesity is a catalyst that fuels disease and is directly responsible for the pathogenesis for the disease claiming the lives of men nationwide.

A Systematic Review of Dietary Supplements and Alternative Therapies for Weight Loss.

OBJECTIVE: Dietary supplements and alternative therapies are commercialized as a panacea for obesity/weight gain as a result of the minimal regulatory requirements in demonstrating efficacy. These products may indirectly undermine the value of guideline-driven obesity treatments. Included in this study is a systematic review of the literature of purported dietary supplements and alternative therapies for weight loss. METHODS: A systematic review was conducted to evaluate the efficacy of dietary supplements and alternative therapies for weight loss in participants aged ≥18 years. Searches of Medline (PubMed), Cochrane Library, Web of Science, CINAHL, and Embase (Ovid) were conducted. Risk of bias and results were summarized qualitatively. RESULTS: Of the 20,504 citations retrieved in the database search, 1,743 full-text articles were reviewed, 315 of which were randomized controlled trials evaluating the efficacy of 14 purported dietary supplements, therapies, or a combination thereof. Risk of bias and sufficiency of data varied widely. Few studies (n = 52 [16.5%]) were classified as low risk and sufficient to support efficacy. Of these, only 16 (31%) noted significant pre/post intergroup differences in weight (range: 0.3-4.93 kg). CONCLUSIONS: Dietary supplements and alternative therapies for weight loss have a limited high-quality evidence base of efficacy. Practitioners and patients should be aware of the scientific evidence of claims before recommending use.

Obesity and genetics.

Genetics is now known to play a substantial role in the predisposition to obesity and may contribute up to 70% risk for the disease. Over a hundred genes and gene variants related to excess weight have been discovered. Yet, genetic obesity risk does not always translate into actual obesity development, suggesting complex interactions between genetic, behavioral, and environmental influences and resulting epigenetic changes. Rare but serious forms of monogenic obesity typically appear in early childhood. Polygenic obesity is most common and demonstrates strong interplay between genes and the obesogenic environment. This review provides an overview of genetic causes of obesity, potential mechanisms of epigenetic changes, and environmental influences that should diminish obesity bias and offer hope for more effective obesity prevention and intervention strategies.

Nurse practitioner students' observations of preceptor engagement in obesity management and weight bias: A mixed-methods approach.

BACKGROUND: Obesity is considered a growing epidemic in the United States. Nurse practitioners (NPs) have the opportunity to serve as leaders in addressing concerns related to disease management, particularly obesity. Currently, we lack an awareness of how NP students are learning obesity management from their preceptors. PURPOSE: Thus, the current study sought to explore how NP students perceive preceptors' behaviors when managing patients with obesity. METHODOLOGICAL ORIENTATION: This study used a mixed-methods design. Participants were asked to report how often they observed their preceptors engage in different strategies when interacting with patients with obesity (e.g., calculate body mass index, identify goals). Students were then asked to respond to the statement: "share observations you made of how patients with obesity were treated in this environment." Students completed 2 clinical rotations during this period and, thus, were asked to answer the questions twice to capture experiences at both clinical sites. SAMPLE: Researchers surveyed 225 NP students completing clinical rotations in 3 settings (Family Practice, Pediatrics, and Obstetrics/Gynecology). CONCLUSIONS: Quantitative results revealed significant differences in the frequency of observed obesity management behaviors by all preceptors. Qualitative results revealed that NP students most often observed preceptors displaying interpersonal warmth without weight bias when working with patients with obesity. Contrary to current literature, this sample of NP students observed their preceptors engaging in positive interactions with individuals with obesity. IMPLICATIONS FOR PRACTICE: Educators must continue to teach students to engage in unbiased behavior toward patients. It is critical to continue to improve obesity management content offered in NP programs.

Weight History in Clinical Practice: The State of the Science and Future Directions.

Eliciting a weight history can provide clinically important information to aid in treatment decision-making. This view is consistent with the life course perspective of obesity and the aim of patient-centered care, one of six domains of health care quality. However, thus far, the value and practicality of including a weight history in the clinical assessment and treatment of patients with obesity have not been systematically explored. For these reasons, the Clinical Committee of The Obesity Society established a task force to review and assess the available evidence to address five key questions. It is concluded that weight history is an essential component of the medical history for patients presenting with overweight or obesity, and there are strong and emerging data that demonstrate the importance of life stage, duration of exposure to obesity, maximum BMI, and group-based trajectory modeling in predicting risk for increased morbidity and mortality. Consideration of these and other patient-specific factors may improve risk stratification and clinical decision-making for screening, counseling, and management. Recommendations are provided for the key elements that should be included in a weight history, and several needs for future clinical research are outlined.

Implications of differing attitudes and experiences between providers and persons with obesity: results of the national ACTION study.

Objective: Our aim was to explore how differing attitudes, expectations, and experiences among people with obesity (PwO) and healthcare providers (HCPs) might have an impact on effectively implementing current obesity treatment guidelines. Methods: Online surveys were conducted among 3,008 adult PwO (BMI≥30 by self-reported height and weight) and 606 HCPs. Results: PwO with weight loss ≥ 10% during the previous three years were more likely to have been diagnosed with obesity and to have discussed a weight loss plan with an HCP. However, only 21% believe HCPs have a responsibility to actively contribute to their obesity treatment. Further, HCPs tend not to effectively communicate the diagnosis of obesity, its nature as a serious and chronic disease, the full range of treatment options, and obesity's implications for health and quality of life. Regarding treatment goals, HCPs more often focus on BMI reduction, while PwO's goals focus on improved functioning, energy, and appearance. HCPs also tend to underestimate their patients' motivation to address their obesity. Twenty-eight percent of HCPs 'completely agreed' that losing weight was a high priority for PwO, whereas more than half of PwO 'completely agreed' that losing weight was a high priority for them. When asked how their HCP could better support them, PwO most often expressed a desire for helpful resources, as well as assistance with specific and realistic goal-setting to improve health. Conclusions: HCPs can more effectively implement obesity treatment guidelines by more clearly and proactively communicating with PwO about their diagnosis, health implications of obesity, desired treatment goals, and the full range of treatment options. HCPs should understand that most PwO believe that managing their disease is solely their own responsibility. HCPs can also encourage more effective conversations by better appreciating their patients' motivation and treatment goals.

Competency in obesity management: An educational intervention study with nurse practitioner students.

BACKGROUND: The National Center for Health Statistics reported that obesity is at epidemic levels in the United States, with an estimated 70.7% of adults affected by overweight and obesity. The disease state of obesity affects all generations and is pervasive among all socioeconomic groups. PURPOSE: This study was designed to examine the impact of implementing educational modules to determine if the intervention improved knowledge and comfort levels for Nurse Practitioner students when managing patients with obesity. METHODS: Nurse Practitioner students completed a survey regarding knowledge and comfort level in managing patients with obesity. Students then completed modules designed to train health care providers on the management of obesity. A postmodule assessment was administered to determine if the obesity management modules improved competency and perceived skills when treating patients with overweight and obesity. RESULTS: Participants' mean score on the knowledge test represented a significant improvement following training. Their comfort level in managing patients with obesity increased. IMPLICATIONS FOR PRACTICE: Implementing these modules in graduate education may be a helpful avenue to improve competency in obesity management. Acknowledging that obesity is a disease and requires a multifaceted approach when helping patients improve their health. This change in perception may lead to better goal-setting with the patient, empathetic understanding, and broader patient involvement in the treatment.

Advanced Practice Nursing student knowledge in obesity management: A mixed methods research study.

BACKGROUND: Obesity, the most prevalent chronic disease affecting multiple systems, is associated with increased mortality and a decreased life expectancy. OBJECTIVES: The purpose of this study was to identify Advanced Practice Nursing (APN) students' confidence of obesity management as well as satisfaction of APN curriculum on and curricular recommendations regarding obesity management. DESIGN: Modified convergent mixed-methods design. SETTING: A university-based college of nursing in the Deep South. PARTICIPANTS: Graduate APN Students. METHODS: An exploratory mixed methods online survey was administered to APN students. The survey included demographics; confidence in obesity management; knowledge of pharmacological treatment; self-reported height and weight; experiences and challenges related to obesity management; and suggestions of curricular content changes for the treatment of obesity that would increase student expertise and confidence. RESULTS: Ninety-nine surveys were completed by 94 female and five male APN students aged 26 to 61 years. The majority (70.7%) were white with BMIs ranging from 19.57 to 51.37 (x̅=27.81). Areas where students were least comfortable were prescribing anti-obesity medications and accurately billing for obesity management. Fourteen percent of APN students reported feeling that their graduate nursing education program did not prepare them well in obesity management, 25.3% reported feeling slightly well prepared, 32% reported feeling moderately well prepared, and 27.8% reported feeling very well or extremely well prepared. Qualitative responses accentuated insecurity in areas such as initiating a discussion on obesity management with patients who have obesity. CONCLUSIONS: Overall, APN students requested that their curriculum incorporate more instruction on how to begin the discussion of weight loss and provide clear evidence-based guidelines that include diet, exercise, and medication options. An efficient way to affect the management and treatment of obesity is to ensure that the next generation of providers is thoroughly prepared to implement the best evidence-based obesity management for patients.

Perceptions of Barriers to Effective Obesity Care: Results from the National ACTION Study.

OBJECTIVE: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Current pharmacotherapies for obesity: A practical perspective.

BACKGROUND AND PURPOSE: To review the currently available pharmacotherapies for obesity management with a particular focus on the United States. METHODS: Narrative review based on literature searches and the latest prescribing information (up to July 2017). CONCLUSIONS: Obesity pharmacotherapies may assist those individuals who have obesity, or overweight with comorbidities, who have failed to maintain weight loss with lifestyle modifications alone (caloric restriction and increased physical activity). Currently approved options in the United States include phentermine for short-term use and five obesity pharmacotherapies that can be used long-term (orlistat, lorcaserin, phentermine-topiramate, naltrexone-bupropion, and liraglutide 3.0 mg). If the use of an obesity pharmacotherapy is indicated, treatment should be selected to provide the most appropriate option for each individual and their circumstances. Variables such as contraindications, individual comorbidities, patient choice, patient readiness to incorporate additional behavioral changes (e.g., alcohol prohibition), and cost should guide choices. IMPLICATIONS FOR PRACTICE: Each of the obesity pharmacotherapies has advantages and disadvantages that can help guide treatment choice. Those receiving treatment may also have individual preferences based on factors such as administration route, frequency of dosing, and/or safety profile. In addition, some options may be particularly appropriate for patients with common obesity-related complications such as depression or diabetes.

Principles on integrating behavioral health into medical homes must not designate leaders as "physicians only".

Nurse practitioners have long included high-quality behavioral health in the care they provide to individuals and families nationwide. Just as the principles of the medical home have been an integral part of nurse practitioners' practice, so has the concept of whole person orientation incorporating both physical and mental or behavioral health care. It is therefore encouraging that organized medicine has embraced integrated physical and behavioral health care in patient-centered medical homes, a position that could help improve the wellbeing of patients all throughout the United States. Although the American Association of Nurse Practitioners (AANP) has long supported such integration, we do not support the physician-centric joint principles included in the current issue of Annals of Family Medicine (The Working Party Group on Integrated Behavioral Healthcare et al., 2014), as they create provider and leadership roles that are too narrow and restrictive for the provision of health care in the 21st century. As written, they limit access to high-quality care and restrict patient choice of health care providers.
