Obesity and advocacy: A joint clinical perspective and expert review from the obesity medicine association and the obesity action coalition - 2024

Background

This joint clinical perspective by the Obesity Medicine Association (OMA) and Obesity Action Coalition (OAC) provides clinicians an overview of the role of advocacy in improving the lives of patients living with the disease of obesity, as well as describes opportunities how to engage in advocacy.

Methods

This joint clinical perspective is based upon scientific evidence, clinical experiences of the authors, and peer review by the OMA leadership. The Obesity Medicine Association is the largest organization of physicians, nurse practitioners, physician associates, and other clinical experts (i.e., over 5000 members at time of print) who are engaged in improving the lives of patients affected by the disease of obesity. The OAC is a national nonprofit organization of more than 80,000 members who are dedicated to serving the needs of individuals living with obesity.

Results

Advocacy involves educational and public policy initiatives that through relationships, networks, and targeted strategies and tactics (e.g., traditional media, social media, petitions, and direct communication with policy makers), promote public awareness and establish public policies that help mitigate bias, stigma, and discrimination, and generally improve the lives of patients living with the disease of obesity.

Conclusions

An objective of advocacy is to foster collective involvement and community engagement, leading to collaborations that help empower patients living with obesity and their clinicians to seek and achieve changes in policy, environment, and societal attitudes. Advocacy may also serve to enhance public awareness, promote prevention, advance clinical research, develop safe and effective evidenced-based therapeutic interventions, and facilitate patient access to comprehensive and compassionate treatment of the complex disease of obesity.

Laser Acupuncture versus Liraglutide in Treatment of Obesity: A Multi-Institutional Retrospective Cohort Study

BACKGROUND

Obesity is a global concern, driving the search for alternative treatments beyond lifestyle changes and medications. Laser acupuncture (LA) shows promise in obesity management, yet few studies compare it with FDA-approved medications. This study aimed to assess and compare LA's impact with liraglutide on weight reduction in obese individuals.

METHODS

Data from the Chang Gung Research Database (CGRD) (2013-2018) were analyzed. Primary outcomes included changes in body weight and BMI within 180 days, with secondary outcomes measuring the proportion achieving 5%, 10%, and 15% weight loss. Adverse events were also assessed.

RESULTS

Of 745 subjects (173 LA users, 572 liraglutide users), LA users lost more weight by day 180 (5.82 ± 4.39 vs. 2.38 ± 5.75 kg; p < 0.001) and had a greater BMI reduction (-2.27 ± 1.73 vs. -0.93 ± 2.25 kg/m2; p < 0.001). More LA users achieved 5% and 10% weight loss compared to liraglutide users (64.2% vs. 22.7%, 26.6% vs. 4.2%; all p < 0.001). After balancing baseline differences, LA's benefits remained significant. No adverse events were reported with LA.

CONCLUSIONS

LA may offer superior weight reduction compared to liraglutide. Future studies should explore LA alone or in combination with liraglutide for obesity management.

Obesity, dyslipidemia, and cardiovascular disease: A joint expert review from the Obesity Medicine Association and the National Lipid Association 2024

Background

This joint expert review by the Obesity Medicine Association (OMA) and National Lipid Association (NLA) provides clinicians an overview of the pathophysiologic and clinical considerations regarding obesity, dyslipidemia, and cardiovascular disease (CVD) risk.

Methods

This joint expert review is based upon scientific evidence, clinical perspectives of the authors, and peer review by the OMA and NLA leadership.

Results

Among individuals with obesity, adipose tissue may store over 50% of the total body free cholesterol. Triglycerides may represent up to 99% of lipid species in adipose tissue. The potential for adipose tissue expansion accounts for the greatest weight variance among most individuals, with percent body fat ranging from less than 5% to over 60%. While population studies suggest a modest increase in blood low-density lipoprotein cholesterol (LDL-C) levels with excess adiposity, the adiposopathic dyslipidemia pattern most often described with an increase in adiposity includes elevated triglycerides, reduced high density lipoprotein cholesterol (HDL-C), increased non-HDL-C, elevated apolipoprotein B, increased LDL particle concentration, and increased small, dense LDL particles.

Conclusions

Obesity increases CVD risk, at least partially due to promotion of an adiposopathic, atherogenic lipid profile. Obesity also worsens other cardiometabolic risk factors. Among patients with obesity, interventions that reduce body weight and improve CVD outcomes are generally associated with improved lipid levels. Given the modest improvement in blood LDL-C with weight reduction in patients with overweight or obesity, early interventions to treat both excess adiposity and elevated atherogenic cholesterol (LDL-C and/or non-HDL-C) levels represent priorities in reducing the risk of CVD.

Relationship between dietary knowledge, food preference, and long-short term health status among Chinese adults

BACKGROUND AND OBJECTIVES

In recent years, with the improvement of people's living standards and changes in dietary patterns, dietary knowledge and food preference have been playing an increasingly crucial role in health. The aim of our study was to examine the relationship between dietary knowledge, food preference, and long-short term health status among Chinese adults aged 18-70.

METHODS AND STUDY DESIGN

This study employed cross-sectional data from the 2015 China Health and Nutrition Survey obtained from 4822 adults. We utilized self-assessed health status as an indicator of long-term health status and utilized sickness in the last four weeks as a measure of short-term health status. Taking advantage of ordered probit regression, long-term health status was regressed on all predictors, while the binary logistic regression was used to analyze the factors influencing short-term health status. The propensity score matching is employed to account for potential selection bias in analysis, thereby increasing the robustness and credibility of results.

RESULTS

The analysis revealed that dietary knowledge and food preference can improve an individual's long-term health status significantly. However, there is no evidence to show that short-term health status is affected by food preference. Furthermore, dietary knowledge is negatively associated with short-term health status.

CONCLUSIONS

These findings highlight the importance of dietary education and healthy eating habits in improving the long-term health status of Chinese adults. The study suggests implications for public health strategies aimed at enhancing the health and well-being of Chinese adults.

Dietary determinants of overnutrition among hypertensive patients in southwest Ethiopia: an ordinal regression model

Overnutrition is a recognized risk factor for hypertension, but evidence is lacking among hypertensive patients for tailored dietary interventions. This study assessed dietary factors in 331 hypertensive patients in southwest Ethiopia. The data was collected through a questionnaire and analyzed using factor analysis. Body mass index (BMI) was calculated, and a BMI above 25 kg m-2 was considered overnutrition. An ordinal logistic regression model was used to model the data and control confounders. Adjusted odds ratio and p-values were reported. Among the 331 respondents, consumption of cereals and grains (57.0%); roots and tubers (58.5); and legumes (50.0%), while 28.6% drink alcohol, was common. About 29.0% (24.1-34.2) had overnutrition (22%, 17.6-26.6%, overweight and 7.0%, 4.5-10.3%, obesity). While the predicted odds of overnutrition were higher among males (AOR = 2.85; 1.35-6.02), married (AOR = 1.47; 0.69-3.12), illiterates (AOR = 2.09; 1.18-3.72), advanced age (AOR = 1.65; 0.61-4.61), government employees (AOR = 6.83; 1.19-39.2), and urban dwellers (AOR = 4.06; 1.76-9.36), infrequent vegetable consumption (AOR = 1.47; 0.72-2.96) and lower and higher terciles of cereals and animal-source food consumption (AOR = 1.56; 0.72-3.34). Overnutrition among hypertensive patients was significantly high and associated with unhealthy dietary consumption, educational status, residence, and occupation, emphasizing the need for targeted dietary counseling.

Effects of phentermine / topiramate extended-release, phentermine, and placebo on ambulatory blood pressure monitoring in adults with overweight or obesity: A randomized, multicenter, double-blind study

Background

A fixed-dose combination of phentermine and extended-release topiramate (PHEN/TPM - approved for weight management) has demonstrated in-clinic reduction of blood pressure (BP). Ambulatory BP monitoring (ABPM) may be a better predictor of cardiovascular disease risk than in-clinic BP.

Methods

This randomized, multicenter, double-blind study enrolled 565 adults with overweight/obesity. Inclusion criteria included participants willing to wear ABPM device for 24 h. Exclusion criteria included screening blood pressure >140/90 mmHg and antihypertensive medications not stable for 3 months prior to randomization. Participants received placebo (n = 184), phentermine 30 mg; (n = 191), or PHEN 15 mg/TPM 92 mg; (n = 190). 24-hour ABPM was performed at baseline and at week 8. The primary endpoint was mean 24-h systolic BP (SBP) as measured by ABPM, in the per protocol population.

Results

Participants were mostly female (73.5 ​%) and White (81.6 ​%), with a mean age of 53.4 years; 32.4 ​% had no hypertension diagnosis or treatment, 62.5 ​% had hypertension using 0 to 2 antihypertensive medications, and 5.1 ​% had hypertension using ≥ 3 antihypertensive medications. Baseline mean SBP/diastolic BP (DBP) was 123.9/77.6 ​mmHg. At week 8, mean SBP change was -0.1 ​mmHg (placebo), +1.4 ​mmHg (phentermine 30 ​mg), and -3.3 ​mmHg (PHEN/TPM). Between-group difference for PHEN/TPM versus placebo was -3.2 ​mmHg (95 ​% CI: -5.48, -0.93 ​mmHg; p ​= ​0.0059). The between-group difference for PHEN/TPM versus phentermine 30 ​mg was -4.7 ​mmHg (95 ​% CI: -6.96, -2.45 ​mmHg; p ​< ​0.0001). Common (>2 ​% in any treatment group) adverse events (i.e., dry mouth, constipation, nausea, dizziness, paresthesia, dysgeusia, headache, COVID-19, urinary tract infection, insomnia, and anxiety) were mostly mild or moderate.

Conclusions

In this randomized, multicenter, double-blind ABPM study, PHEN/ TPM reduced SBP compared to either placebo or phentermine 30 mg (Funding: Vivus LLC; ClinicalTrials.gov: NCT05215418).

Obesity, thrombosis, venous disease, lymphatic disease, and lipedema: An obesity medicine association (OMA) clinical practice statement (CPS) 2023

Background

This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) is intended to provide clinicians with an overview on obesity, thrombosis, venous disease, lymphatic disease, and lipedema.

Methods

The scientific support for this CPS is based upon published citations, clinical perspectives of OMA authors, and peer review by the Obesity Medicine Association leadership.

Results

Topics in this CPS include obesity, thrombosis, venous disease, lymphatic disease, and lipedema. Obesity increases the risk of thrombosis and cardiovascular disease via fat mass and adiposopathic mechanisms. Treatment of thrombosis or thrombotic risk includes healthful nutrition, physical activity, and the requisite knowledge of how body weight affects anti-thrombotic medications. In addition to obesity-related thrombotic considerations of acute coronary syndrome and ischemic non-hemorrhagic stroke, this Clinical Practice Statement briefly reviews the diagnosis and management of clinically relevant presentations of deep vein thromboses, pulmonary embolism, chronic venous stasis, varicose veins, superficial thrombophlebitis, lipodermatosclerosis, corona phlebectatica, chronic thromboembolic pulmonary hypertension, iliofemoral venous obstruction, pelvic venous disorder, post-thrombotic syndrome, as well as lymphedema and lipedema - which should be included in the differential diagnosis of other edematous or enlargement disorders of the lower extremities.

Conclusions

This Obesity Medicine Association (OMA) Clinical Practice Statement (CPS) on obesity, thrombosis, and venous/lymphatic disease is one of a series of OMA CPSs designed to assist clinicians in the care of patients with the disease of obesity.
