Barriers to Obesity Management: Patient and Physician Factors

Efficacy of phentermine/topiramate extended release in weight management and metabolic profiles: A multicentre study in South Korea

AIMS

Clinical trials have demonstrated the effectiveness of the phentermine and topiramate combination in weight management. This research evaluated the efficacy and safety of phentermine/topiramate extended release (ER) for weight management, focusing on alterations in body weight and metabolic parameters in routine clinical practice.

MATERIALS AND METHODS

We retrospectively included people with obesity who initiated phentermine/topiramate ER between January 2020 and April 2023 at 10 tertiary hospitals in South Korea. The study assessed body weight changes at 5-6 months and for those who continued, at 12 months, along with metabolic parameters. Total body weight was measured using calibrated electronic scales with participants in light indoor clothing.

RESULTS

The cohort included 1839 patients (540 men and 1299 women), with a 5-6-month continuation rate of 48%. At 5-6 months, the mean weight reduction was 7.9%, with sex-specific losses of 7.1% in men and 8.2% in women. Over 56% of participants achieved more than 5% weight loss, with 23% exceeding a 10% reduction. Younger participants, women and those with moderate to severe obesity exhibited more pronounced weight loss compared to older men and individuals with mild obesity, respectively. Concurrently, phentermine/topiramate ER treatment improved glucose regulation, lipid profiles and decreased blood pressure: the HbA1c decreased by 0.4 ± 0.9%, low-density lipoprotein (LDL) cholesterol by 10 ± 32 mg/dL and systolic blood pressure by 6 ± 15 mmHg (all p < 0.001). Treatment was well-tolerated, with a 15% incidence of mild adverse events like paresthesia, dry mouth and insomnia. At 12 months, patients who persisted in treatment (21%) experienced an average weight loss of 9.6%, with 65% surpassing a 5% weight loss.

CONCLUSION

The study suggests phentermine/topiramate ER is an effective option for obesity management in a South Korean population, though long-term adherence remains a challenge.

Factors influencing patients to choose one obesity treatment over another: a qualitative study

BACKGROUND

When deciding a treatment option for the disease of obesity, knowing what the patient's preferences are and what factors have influenced them can support healthcare professionals (HCPs) in tailoring their management plan. Little is known about patient preferences for obesity treatment. The present study was designed to identify factors that may influence these preferences.

OBJECTIVE

We aimed to identify factors affecting patient preferences and subsequent obesity treatment preferences among those seeking treatment for obesity-related disorders.

METHODS

Using a participatory action research design, we conducted World Café focus groups as part of a triangulation process with previously collected individual interviews and photovoice. Using purposive sampling, 12 patients with obesity complications of chronic kidney disease, type 2 diabetes, and metabolic dysfunction-associated steatotic liver disease took part. Thematic analysis was conducted to review themes, determine their significance, and report the findings.

RESULTS

Five themes emerged from the World Café on what influences patient treatment choice, which were 1) lack of resources, 2) healthcare professionals' knowledge gaps, 3) lack of understanding, 4) emotional impact, and 5) support from family, friends, and HCPs. This data was then reviewed with the findings from the previous methodologies of one-to-one interviews and photovoice. Overall, four main themes were identified, which were 1) structural factors, 2) physical and emotional impact, 3) knowledge (of healthcare professionals and patients), and 4) support.

CONCLUSION

This study demonstrates the importance of ensuring access to all treatment options by developing effective treatment plans with clear information for patients.

Obesity and Hypertension: Etiology and the Effects of Diet, Bariatric Surgery, and Antiobesity Drugs

Obesity-related hypertension (HTN) is a growing global health concern, being a significant contributor to cardiovascular morbidity and mortality. The article reviews the complex pathophysiological mechanisms involved in the link between obesity and HTN, including neurohormonal activation, inflammation, insulin resistance, and endothelial dysfunction. The role of adipokines, specifically leptin and adiponectin, in blood pressure regulation is highlighted, along with the impact of advanced glycation end-products on vascular function. We discuss the effectiveness of lifestyle therapies, including weight loss, and diet for the management of obesity HTN. We also discuss the utilization of pharmacologic agents, including GLP-1 receptor agonists, and the impact of bariatric surgery on long-term blood pressure control. Despite enhanced treatment, significant barriers to treatment exist, including obesity stigma, limited access to health care, and adherence problems. Future research must focus on personalized approaches, like pharmacogenomics, to optimize hypertension treatment in the obese.

Global barriers to decision makers for prioritizing interventions for obesity

The treatment of obesity remains underprioritized. New pharmacologic options for the treatment of obesity have shown effectiveness and safety but are not widely reimbursed. Despite the unmet need and the existence of effective prevention and treatment strategies, substantial barriers exist to effectively address obesity as a disease. The purpose of this scoping review was to investigate the barriers for decision makers in prioritizing interventions for obesity and to seek out interconnection between barriers to prevention and treatment. A scoping review was conducted using a systematic search of both scientific databases and Health Technology Assessment (HTA) databases. Studies that addressed barriers to reimbursement or prioritization of obesity treatment and prevention were included. A total of 26 articles and 14 HTAs were included. Four main barriers for decision makers to prioritize new interventions for obesity were identified: perceptions, knowledge, economics, and politics. There was a high degree of interconnectedness among barriers, as well as large overlaps between barriers in relation to bariatric surgery, pharmacologic treatments, and prevention regulation. Multiple barriers exist that impact decision makers in prioritizing interventions for treating obesity. A strong interconnectedness of the barriers was found, indicating a systems approach to improve global prioritization to address the disease. This study suggests that decision makers should carefully consider all main barriers when addressing the obesity epidemic.

Breaking the Silence on Obesity

Obesity is a significant global public health concern, and health care providers play a crucial role in addressing it by offering healthy lifestyle counseling and weight management support. Evidence demonstrates that even brief counseling on healthy behaviors can lead to meaningful changes and sustained weight management. However, weight consultations are often underutilized in primary care due to various barriers, including biases against patients with obesity, misconception of physicians with obesity, or concerns about stigmatizing them by initiating discussions about weight. This paper explores the impact of biases, misconceptions, and stigma on the communication and treatment of patients with obesity and proposes strategies to overcome these challenges. Practical solutions include fostering inclusive health care environments for individuals of all body sizes and utilizing the 5A model (Ask, Assess, Advise, Agree, Assist) to guide respectful and effective weight management conversations.

Efficacy of Dichrostachys Glomerata Supplementation on Overweight and Mildly Obese Adult's Weight, Mood, and Health-Related Quality of Life: A Randomized Double-Blind Placebo-Controlled Trial

Despite their widespread use, research is needed to evaluate the weight loss and related health/wellness outcomes of herbal plants. Preliminary research found that the fruit of Dichrostachys glomerata is safe and has potential weight loss effects. This study aimed to examine the effect of a standardized powder of D. glomerata fruit pods (DYG-400®) on weight, food cravings, mood, and health-related quality of life of overweight and mildly obese adults. In this CONSORT-compliant double-blind placebo-controlled trial, 56 adults (Mean [M] age = 44.50, M [body mass index] BMI = 31.66) were randomized to either the D. glomerata Group (DG; 300 mg/d) or Placebo Group (PG; rice protein, 300 mg/d) for 60 days. Participants weight was assessed along with self-report assessments of the Food Cravings Questionnaire, CDC Health-related Quality of Life, Perceived Stress Scale, Trait Anxiety Inventory, and Profile of Mood States at Baseline, Day 30, and Day 60. The data were collected from March 2023 to June 2023 and stored electronically, and analyzed using general linear models with repeated measures. DG lost more weight at Day 60 compared to PG, p = .05 (4.11 vs. 2.19 lbs). DG had reduced food cravings from Baseline to Day 30 and Day 60 compared to PG, p < .001. Perceived stress, p < .001, and mood, p = .017, improved from Baseline to Day 60 for DG compared to PG. Anxiety decreased from Baseline to Day 60 for DG and from Baseline to Day 30 for PG, p < .001. Health-related Quality of Life improved for DG compared to PG, p < .001. D. glomerata (DYG-400®) may be an effective herbal intervention to promote weight loss and health. Extended clinical trials across diverse populations and settings are needed.

The Patient's Journey in Obesity within the United States: An Exercise of Resilience against Disease

Obesity is often viewed as a result of patient failure to adhere to healthy dietary intake and physical activity; however, this belief undermines the complexity of obesity as a disease. Rates of obesity have doubled for adults and quadrupled for adolescents since the 1990s. Without effective interventions to help combat this disease, patients with obesity are at increased risk for developing type 2 diabetes, heart attack, stroke, liver disease, obstructive sleep apnea, and more. Patients often go through several barriers before they are offered pharmacotherapy or bariatric surgery, even though evidence supports the use of these interventions earlier. This partially stems from the cultural barriers associated with using these therapies, but it is also related to healthcare provider bias and limited knowledge of these therapies. Finally, even when patients are offered treatment for obesity, they often run into insurance barriers that keep them from treatment. There needs to be a cultural shift to accept obesity as a disease and improve access to effective treatments sooner to help decrease the risk of health complications associated with obesity.

Long-term impact of weight loss in people with class II obesity on the overall burden of disease: Evidence from the National Health Screening Cohort in Korea

BACKGROUND

Obesity is known to increase overall disease burden but does obesity management actually help reduce disease burden?

OBJECTIVES

To investigate the effects of weight loss on disease burden in people with obesity using the National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) in Korea.

SETTING

Pure longitudinal observational study using Nationwide cohort database.

METHODS

Out of 514,866 NHIS-HEALS cohort, participants with class II obesity in Asia-Pacific region (30 ≤ body mass index [BMI] < 35) who underwent health check-up provided by NHIS during 2003-2004 (index date) were included. All final participants continued to receive a total of 5 biennial health check-ups over the next 10 years without missing. A group-based trajectory model (GBTM) was used to categorize subjects based on 10-year BMI change patterns. The changes of co-morbidities, healthcare resource utilization, and medical cost were analyzed.

RESULTS

The final study subjects (9857) were categorized into 3 trajectory clusters based on the pattern of BMI (kg/m2) change: maintenance (57.35%) with an average change of -.02 ± .06, loss (38.65%) with -.04 ± .08, and substantial loss (4.0%) with -.10 ± .18. The annual increases in the number of co-morbidities per subject in each cluster were .18, .18, and .16 (all P < .001), respectively. The increase of healthcare resource utilization over time was lowest for the substantial loss compared to maintenance and loss. With each passing year, the average annual total healthcare cost increased by ₩21,200 ($16.48, P = .034) and ₩10,500 ($8.16, P = .498) in the maintenance and loss, respectively, but decreased by ₩62,500 ($48.59, P = .032) in the substantial loss.

CONCLUSIONS

Weight loss in people with obesity was associated with a reduced burden of disease, as evidenced by lower co-morbidity, healthcare resource utilization rate, and decreased medical costs. This study highlights the potential positive long-term impact on Korean society when actively managing weight in individuals with obesity.

Implementation of a pharmacist-led weight loss service to improve medication access and weight loss

BACKGROUND

Obesity is a prevalent medical condition that can contribute to an increased risk of developing serious comorbidities, leading to an increase in hospitalizations, morbidity, and mortality. Many of these medical conditions can be improved with weight loss.

OBJECTIVES

This project was designed to improve weight loss outcomes and assess the utilization of services provided by clinical pharmacists for collaborative weight loss management.

METHODS

The study design was a single-center, retrospective, and quality improvement study within 3 outpatient clinics at Tufts Medical Center. Patients referred to the pharmacist-led weight loss service from September 1 to October 31, 2022, and continued care for up to 6 months were included. Pharmacist services included selection of weight loss medication, assistance with medication access, device teaching and dose titration, lifestyle counseling, and follow-up. The primary outcome was percent weight loss from baseline.

RESULTS

Seventy-nine patients were referred to the pharmacist-led weight loss service. Mean age of patients was 51 years (SD ±13). Sixty-one patients were female (77.2%). Median baseline weight was 105.5 kg (IQR 93.1 to 120.5 kg) and body mass index 38.1 kg/m2 (IQR 33.9 to 43.5 kg/m2). The median percent weight loss from baseline through the end of the study duration was -8.0% (IQR -3.1 to -12.1%).

CONCLUSION

Pharmacists were able to effectively provide weight loss care through a pharmacist-led weight loss service by aiding in medication access, providing education on devices and lifestyle management, and engaging in frequent follow-up. Future directions of this study include expansion of the pharmacist-led weight loss service to other ambulatory care clinics within TMC.

Efficacy and Safety of Once-Weekly Subcutaneous Semaglutide in Overweight or Obese Adults: A Systematic Review with Meta-Analysis

BACKGROUND

To evaluate the efficacy and safety of once-weekly subcutaneous semaglutide treatment in overweight or obese patients without type 2 diabetes.

METHODS

Randomized clinical trials that assessed the impact of once-weekly semaglutide on body weight and safety outcomes in overweight or obese patients were retrieved from PubMed, EMBASE, and Lilacs up to November 2023. Risk of bias was assessed with RoB 2.0, and certainty of evidence (CoE) with GRADE. A random-effects meta-analysis was conducted.

RESULTS

Ten publications, with 22.155 patients, were included. Semaglutide decreased relative body weight (MD: -11.80; 95%CI: -13.53 to -10.07; CoE: High), absolute body weight (MD: -11.58; 95%CI: -13.25 to -9.90; CoE: High) and BMI (MD: -4.15; 95%CI: -4.85 to -3.45; CoE: High). Semaglutide also increased the proportion of patients who achieved 5%, 10%, and 15% of weight loss ([weight loss≥5%: RR 2.29, 95% CI: 1.88 to 2.80; CoE: High]; [weight loss≥10%: RR 4.54, 95% CI: 3.45 to 5.98; CoE: High]; [weight loss≥15%: RR 8.29, 95%CI: 5.54 to 12.39; CoE: High]). Semaglutide leads to small risk to adverse events (RR: 1.03; 95%CI: 1 to 1.06; CoE: High), no difference in the serious adverse events (RR: 1.07; 95%CI: 0.70 to 1.62; CoE: Low), but increases in the risk to discontinued treatment (RR: 2.03; 95%CI: 1.87 to 2.20; CoE: High) and gastrointestinal adverse events (RR: 3.26; 95%CI: 1.99 to 5.34; CoE: Moderate).

CONCLUSION

This up-to-date systematic review highlights that once-weekly semaglutide treatment resulted in clinically important weight loss, becoming a promising adjuvant therapy for obesity.

Comparing the Efficacy of Digital and In-Person Weight Loss Interventions for Patients with Obesity and Glycemic Disorders: Evidence from a Randomized Non-Inferiority Trial

Digital weight loss interventions present a viable and cost-effective alternative to traditional therapy. However, further evidence is needed to establish the equal effectiveness of both approaches. This randomized controlled non-inferiority trial aimed to compare the effects of an intensive in-person weight loss intervention program with Vitadio digital therapy. One hundred patients with obesity and diagnosed with type 2 diabetes, prediabetes, or insulin resistance were enrolled and randomly assigned to one of the two treatment groups. Over a 6-month period, the control group received five in-person consultations with a physician who specialized in obesity treatment, a dietitian and/or a nutrition nurse, while the intervention group followed the digital program based on a multimodal therapeutic approach. The extent of weight loss was assessed and compared between the groups. Additionally, changes in body composition and metabolic parameters for the digital intervention group were analyzed. The study results demonstrated comparable effectiveness of both treatments for weight reduction. The positive effects of Vitadio were further evidenced by favorable changes in body composition and lipid metabolism and improved glycemic control in the intervention group. These findings suggest that Vitadio is an effective tool for assisting patients with managing obesity and preventing diabetes progression.

Patient perspectives about treatment preferences for obesity with complications

Objective

Obesity and many of its comorbidities can be improved by nutritional therapy, lifestyle modification, pharmacotherapy, and surgical intervention. Relatively little is known about patients' preferences for the range of obesity treatments. The present study was undertaken to identify factors that may influence these preferences. By evaluating patient-preferred treatment options and factors influencing patients, treatment adherence and efficacy may be improved. Our objective was to identify factors that influence patient preferences and subsequent choice of obesity treatment among those seeking treatment for obesity-related complications.

Methods

Participatory action research, using purposeful sampling, was used to recruit 33 patients with obesity complications. Recruitment took place in specialist clinics for non-alcoholic fatty liver disease, diabetes, hypertension, and chronic kidney disease. Sixteen males and 17 females aged 18-70 years with a BMI>35 kg/m2 were recruited. Prior to the interview, participants watched a 60-min video explaining nutritional therapies, pharmacotherapies, and surgical therapies in equipoise. Data were collected in one-to-one semi-structured interviews using zoom or the telephone; reflective thematic analysis was used.

Results

Four themes emerged: 1) structural factors, 2) autonomy, 3) interaction with formal care, and 4) the emotional and physical consequences of obesity. 39% of participants preferred nutritional therapy with support from medical professionals. 27% chose bariatric surgery. 24% chose pharmacotherapy alone, while 6% chose pharmacotherapy combined with nutritional therapy, 3% of participants wanted no intervention.

Conclusion

The challenges can be addressed by increasing support for healthcare professionals toward enhancing both their knowledge and the health literacy of patients. Future research should focus on improving access to treatment pathways for patients as well as developing health literacy programs and educational programs for healthcare professionals.

Obesity and Cancer Rehabilitation for Functional Recovery and Quality of Life in Breast Cancer Survivors: A Comprehensive Review

Obesity is a global health challenge with increasing prevalence, and its intricate relationship with cancer has become a critical concern in cancer care. As a result, understanding the multifactorial connections between obesity and breast cancer is imperative for risk stratification, tailored screening, and rehabilitation treatment planning to address long-term survivorship issues. The review follows the SANRA quality criteria and includes an extensive literature search conducted in PubMed/Medline, Web of Science, and Scopus. The biological basis linking obesity and cancer involves complex interactions in adipose tissue and the tumor microenvironment. Various mechanisms, such as hormonal alterations, chronic inflammation, immune system modulation, and mitochondrial dysfunction, contribute to cancer development. The review underlines the importance of comprehensive oncologic rehabilitation, including physical, psychological, and nutritional aspects. Cancer rehabilitation plays a crucial role in managing obesity-related symptoms, offering interventions for physical impairments, pain management, and lymphatic disorders, and improving both physical and psychological well-being. Personalized and technology-driven approaches hold promise for optimizing rehabilitation effectiveness and improving long-term outcomes for obese cancer patients. The comprehensive insights provided in this review contribute to the evolving landscape of cancer care, emphasizing the importance of tailored rehabilitation in optimizing the well-being of obese cancer patients.

Attitude and Belief of Healthcare Professionals Towards Effective Obesity Care and Perception of Barriers; An Updated Systematic Review and Meta-analysis

BACKGROUND

Obesity is a serious chronic disease that adversely affects health and quality of life. However, a significant percentage of people do not participate in or adhere to weight loss programs. Therefore, a multidisciplinary approach is needed to identify critical barriers to effective obesity management and to examine health practitioners' attitudes and behaviors towards effective obesity treatment.

METHODS

This systematic review was conducted in accordance with PRISMA 2020. Eligible studies were identified through a systematic review of the literature using Medline, Scopus, Cochrane, Google Scholar, Web of Science, and Embase databases from January 1, 2011 to March 2, 2021.

RESULTS

A total of 57 articles were included. Data on 12663 physicians were extracted from a total of 35 quantitative articles. Some of the most commonly perceived attitude issues included "obesity has a huge impact on overall health", "obesity is a disease" and "HCPs are to blame". Health professionals were more inclined to believe in "using BMI to assess obesity," "advice to increase physical activity," and "diet/calorie reduction advice." The major obstacles to optimal treatment of obesity were "lack of motivation", "lack of time" and "lack of success".

CONCLUSION

Although the majority of health care professionals consider obesity as a serious disease which has a large impact on overall health, counseling for lifestyle modification, pharmacologic or surgical intervention occur in almost half of the visits. Increasing the length of physician visits as well as tailoring appropriate training programs could improve health care for obesity.

A Survey of Obesity Education and Training in United States Pharmacy Schools

OBJECTIVE

To assess how obesity is addressed in Doctor of Pharmacy (PharmD) schools and colleges, identify the extent to which core obesity competencies are covered in the curricula, and identify opportunities for expanding obesity management training.

METHODS

An online survey was conducted with PharmD program leaders in the United States. Respondents answered questions regarding obesity education in their pharmacy school curricula. Data were analyzed in aggregate, using descriptive statistics.

RESULTS

We collected responses from 75 of 150 (50%) PharmD programs. One-third (32%) of respondents thought their graduating students were very prepared to discuss obesity pharmacotherapy (anti-obesity medication) options with patients. A total of 45% reported obesity pharmacological treatment was covered to a great extent. Few respondents (19%) were very familiar with anti-obesity medications; 21% thought their students were similarly familiar. No programs covered weight stigma and discrimination to a great extent. Most respondents (88%) believed obesity education was fairly/very important to include in PharmD curricula, and 96% thought it was similarly appropriate to include. But 72% indicated that expanding obesity education was not a priority/low priority. Lack of room in the curricula was cited as the greatest barrier, with 60% of PharmD programs reporting this to be a large barrier.

CONCLUSION

Pharmacists, as medication experts, are key members of the care team. However, obesity management/pharmacotherapy is not emphasized in most pharmacy schools. Therefore, pharmacists are not well-prepared to provide counseling on medications for obesity. Leveraging guidance on core obesity competencies and available resources could help expand obesity education in pharmacy schools.

Achieving consensus on the language of obesity: a modified Delphi study

BACKGROUND

Obesity is recognized by the World Health Organization as a chronic disease. As such, it should be referred to using the language of chronic diseases, with correct and established terminology and definitions. This study was designed to map the current language used to discuss obesity and to compare this with the standard language used for chronic disease.

METHODS

We performed a modified Delphi study to identify the language of chronic disease that is being used in the context of obesity, and to identify discrepancies and potential use of inadequate language with respect to the standard language used for chronic diseases. Participants (n = 24) were identified from relevant stakeholder groups and desk research, and included patients, healthcare professionals, policymakers, researchers, industry, and payers (social insurers) of 18 nationalities/regions in Europe, North/South America, and South Africa. Participants were enrolled between 20.10.2020 and 30.10.2020. The study comprised two rounds of qualitative surveys. In Round 1, participants responded to six open-ended questions. Round 2 comprised 38 statements based on key terms/themes identified in Round 1 and covered the definition, causes, progression, treatment, management, and complications of obesity. Consensus was defined as ≥70% participant agreement on a statement.

FINDINGS

All participants completed Round 1 and 23 participants completed Round 2. In Round 2, consensus was reached for 28 of the 38 statements. Participants reached a consensus regarding the use of statements that acknowledge the heterogeneous nature of obesity, but not on the use of statements that: defined obesity based on body mass index; regarded psychological, physical, or physiological factors among the main causes of obesity; or implied that weight loss should be the aim of obesity treatment.

INTERPRETATION

This study uses expert consensus to provide insight into the language used to describe obesity as a chronic disease, and forms the basis for a unified language of obesity.

Effects of the probiotic Lactiplantibacillus plantarum IMC 510® on body composition, biochemical parameters, gut microbiota composition and function, and clinical symptoms of overweight/obese subjects

BACKGROUND AND AIM

In recent decades, obesity prevalence has reached epidemic proportions and considering the pivotal role of gut microbiota (GM) in the regulation of energy balance, alternative non-pharmacological approaches involving probiotics' administration have been proposed. The aim of the present study was to evaluate the effect of Lactiplantibacillus plantarum IMC 510® supplementation on anthropometric and biochemical parameters, GM composition and functionality, and gastrointestinal and general symptoms of overweight/obese subjects.

METHODS

Forty overweight/obese subjects were randomly assigned to daily consume the probiotic Lactiplantibacillus plantarum IMC 510® or placebo for 3 months. Before and after the administration period, anthropometric and biochemical parameters, self-administered questionnaires, and plasma and stool samples were obtained from each participant. The GM characterization was performed with 16S rRNA sequencing, while fecal short (SCFAs) and medium (MCFAs) chain fatty acids were analyzed with a gas chromatography-mass spectrometry protocol.

RESULTS

Compared to placebo, probiotic supplementation determined a significant decrease in body weight, BMI, waist circumference, waist-to-height ratio, and blood glucose. Moreover, probiotic administration produced a significant decrease of the genera Hafnia-Obesumbacterium and Romboutsia and an increase of Succiniclasticum spp.; conversely, placebo administration resulted in the decrease of Actinomycetaceae and an increase of both Alloprevotella spp. and of the levels of pro-inflammatory hexanoic and heptanoic acids.

CONCLUSION

Thanks to its effect in increasing some beneficial gut bacteria and lowering effects on waist circumference, fasting glucose levels and gastrointestinal symptoms of obese subjects, Lactiplantibacillus plantarum IMC 510® supplementation could represent a future and encouraging strategy for the prevention or treatment of obesity.

Prioritizing obesity treatment: expanding the role of cardiologists to improve cardiovascular health and outcomes

Obesity is a major risk factor for cardiovascular disease, yet management remains poor. Cardiologists and healthcare professionals treating people with high cardiovascular risk are in a position to address overweight and obesity to improve cardiovascular health. There are several treatment options for obesity, which are associated with numerous health benefits. Modest weight reductions of 5-10% improve cardiovascular risk factors, with greater weight loss bringing about greater benefits. Anti-obesity medications can support weight reduction when lifestyle modifications alone are insufficient. The weight loss induced by these treatments can improve cardiovascular risk, and some therapies - such as glucagon-like-peptide-1 analogues - may promote these benefits independently of weight loss. Bariatric surgery can induce greater weight losses than other treatment modalities and is associated with numerous health benefits, but newer medications such as semaglutide and those in development, such as tirzepatide, produce robust weight loss efficacy that is approaching that of bariatric surgery. Healthcare professionals must approach this disease with compassion and collaborate with patients to develop sustainable plans that improve health and maintain weight loss over the long term.

A Conceptual Model for Mobile Health-enabled Slow Eating Strategies

Ingestive behaviors (IBs) (eg, bites, chews, oral processing, swallows, pauses) have meaningful roles in enhancing satiety, promoting fullness, and decreasing food consumption, and thus may be an underused strategy for obesity prevention and treatment. Limited IB monitoring research has been conducted because of a lack of accurate automated measurement capabilities outside laboratory settings. Self-report methods are used, but they have questionable validity and reliability. This paper aimed to present a conceptual model in which IB, specifically slow eating, supported by technological advancements, contributes to controlling hedonic and homeostatic processes, providing an opportunity to reduce energy intake, and improve health outcomes.

Twelve-Year Trajectory of Disease Burden and Mortality by Obesity Level in Korea: Analysis of the National Health Insurance Service Database

INTRODUCTION

Despite increases in obesity prevalence, awareness of obesity as a disease requiring active treatment remains lacking in Korea. We investigated differences in medical problems and expenditures and mortality across obesity categories using 12-year data from the National Health Insurance Service.

MATERIALS AND METHODS

Individuals aged 40-79 years who underwent medical examinations during 2003-2004 (n = 415,201) were divided based on Asian body mass index (kg/m²) criteria: normal weight (18.5 to < 23.0, 36.4%), overweight (23.0 to < 25.0, 28.3%), obesity (25.0 to < 30.0, 32.5%), and severe obesity (≥ 30.0, 2.8%). Medical problems and expenditures were fitted to linear mixed models. Mortality was analyzed via Cox proportional-hazards model.

RESULTS

More severe obesity was associated with a higher rate of medical problems, relative to normal weight: coefficient = 0.31 (95% confidence interval [CI], 0.30-0.32) for overweight, 0.61 (0.60-0.61) for obesity, and 1.07 (1.04-1.09) for severe obesity. A similar association was observed for medical expenditure: coefficient = 8.85 (95%CI, 6.80-10.89) for overweight, 20.04 (18.07-22.01) for obesity, and 48.76 (43.66-53.86) for severe obesity. Relative to overweight participants, those with normal weight and severe obesity exhibited a higher mortality risk (hazard ratio [HR] 1.21 [95%CI, 1.18-1.25] for normal; 1.27 [1.19-1.36] for severe obesity). In age-specific analyses, mortality risk was the highest for participants with severe obesity, aged < 60 years (HR, 1.58 [95%CI, 1.41-1.77]).

CONCLUSION

Disease burden including medical problems and expenditure, and mortality in middle-aged adults, increased proportionally to the degrees of obesity. Health policies and medical systems aimed at reducing the burden of obesity may help reduce the burden of disease on society.

The Related Metabolic Diseases and Treatments of Obesity

Obesity is a chronic disease characterized by the abnormal or excessive accumulation of body fat, affecting more than 1 billion people worldwide. Obesity is commonly associated with other metabolic disorders, such as type 2 diabetes, non-alcoholic fatty liver disease, cardiovascular diseases, chronic kidney disease, and cancers. Factors such as a sedentary lifestyle, overnutrition, socioeconomic status, and other environmental and genetic conditions can cause obesity. Many molecules and signaling pathways are involved in the pathogenesis of obesity, such as nuclear factor (NF)-κB, Toll-like receptors (TLRs), adhesion molecules, G protein-coupled receptors (GPCRs), programmed cell death 1 (PD-1)/programmed death-ligand 1 (PD-L1), and sirtuin 1 (SIRT1). Commonly used strategies of obesity management and treatment include exercise and dietary change or restriction for the early stage of obesity, bariatric surgery for server obesity, and Food and Drug Administration (FDA)-approved medicines such as semaglutide and liraglutide that can be used as monotherapy or as a synergistic treatment. In addition, psychological management, especially for patients with obesity and distress, is a good option. Gut microbiota plays an important role in obesity and its comorbidities, and gut microbial reprogramming by fecal microbiota transplantation (FMT), probiotics, prebiotics, or synbiotics shows promising potential in obesity and metabolic syndrome. Many clinical trials are ongoing to evaluate the therapeutic effects of different treatments. Currently, prevention and early treatment of obesity are the best options to prevent its progression to many comorbidities.
