The number and complexity of obesity treatments has increased rapidly in recent years. This is driven by the approval of new anti-obesity medications (AOMs) that produce larger degrees of weight loss than previously approved AOMs. Unfortunately, access to these highly effective therapies and to integrated team-based obesity care is limited by intra-/interpersonal patient, institutional/practitioner, community, and policy factors. We contextualized these complexities and the impact of patients' social drivers of health (SDOH) by adapting the social ecological model for obesity. Without multi-level intervention, these barriers to care will deepen the existing inequities in obesity prevalence and treatment outcomes among historically underserved communities. As General Internal Medicine (GIM) physicians, we can help our patients navigate the complexities of evidence-based obesity treatments. As care team leaders, GIM physicians are well-positioned to (1) improve education for trainees and practitioners, (2) address healthcare-associated weight stigma, (3) advocate for equity in treatment accessibility, and (4) coordinate interdisciplinary teams around non-traditional models of care focused on upstream (e.g., policy changes, insurance coverage, health system culture change, medical education requirements) and downstream (e.g., evidence-based weight management didactics for trainees, using non-stigmatizing language with patients, developing interdisciplinary weight management clinics) strategies to promote optimal obesity care for all patients.

BACKGROUND:This study aimed to explore whether patients' perception of procedural fairness in physicians' communication was associated with willingness to follow doctor's recommendations, self-efficacy beliefs, dietary behaviors, and body mass index. METHODS:(43.6% Black, 40.7% Hispanic/Latino, 55.8% female, mean age = 50 years), who enrolled in a weight management study in two New York City healthcare institutions. We conducted ordinary least squares path analyses with bootstrapping to explore direct and indirect associations among procedural fairness, willingness to follow recommendations, self-efficacy, dietary behaviors, and body mass index, while controlling for age and gender. RESULTS:Serial, multiple mediator models indicated that higher procedural fairness was associated with an increased willingness to follow recommendations which, in turn, was associated with healthier dietary behaviors and a lower BMI (indirect effect =  - .02, SE = .01; 95% CI [- .04 to - .01]). Additionally, higher procedural fairness was associated with elevated dietary self-efficacy, which was, in turn, was associated with healthier dietary behaviors and lower BMI (indirect effect =  - .01, SE = .003; 95% CI [- .02 to - .002]). CONCLUSIONS:These findings highlight the importance of incorporating procedural fairness in physician-patient communication concerning weight management in diverse primary care patients.

BACKGROUND:Weight stigma is a fundamental cause of health inequality. Body positivity may be a counterbalance to weight stigma. Social media is replete with weight-stigmatizing content and is a driver of poor mental health outcomes; however, there remains a gap in understanding its potential to mitigate the prevalence and impact of harmful messaging and to promote positive effects on a large scale. OBJECTIVE:We selected musical artist Lizzo, whose brand emphasizes body positivity and empowerment, for an instrumental case study on the discourse on social media and specifically Instagram. We focused on 3 domains, including body positivity, physical health, and emotional well-being. These domains challenge social norms around weight and body size and have the potential to positively affect the physical and psychological health of people with diverse body sizes. METHODS:We evaluated posts by Lizzo, comments from Instagram users, and replies to comments over a 2-month period (October 11 to December 12, 2019). Two coders rated Lizzo's posts and Instagram users' comments for their sentiments on the 3 domains. Replies to Instagram users' comments were assessed for their reactions to comments (ie, did they oppose or argue against the comment or did they support or bolster the comment). Engagement metrics, including the number of "likes," were also collected. RESULTS:The final sample included 50 original posts by Lizzo, 250 comments from Instagram users, and 1099 replies to comments. A proportion of Lizzo's content included body positive sentiments (34%) and emotional well-being (18%); no posts dealt explicitly with physical health. A substantial amount Instagram users' comments and replies contained stigmatizing content including the use of nauseated and vomiting emojis, implications that Lizzo's body was shameful and should be hidden away, accusations that she was promoting obesity, and impeachments of Lizzo's health. In spite of the stigmatizing content, we also discovered content highlighting the beneficial nature of having positive representation of a Black woman living in a larger body who is thriving. Moreover, analysis of the discourse between users illustrated that stigmatizing expressions are being combated online, at least to some degree. CONCLUSIONS:This study demonstrates that Lizzo has exposed millions of social media users to messages about body positivity and provided more visibility for conversations about weight and shape. Future research should examine the extent to which body positive messages can lead to greater acceptance of individuals living in larger bodies. Instagram and other social media platforms should consider ways to reduce body-shaming content while finding ways to promote content that features diverse bodies. Shifting the landscape of social media could decrease stereotypes about weight and shape while increasing dialog about the need for greater acceptance and inclusion of people with diverse bodies.

OBJECTIVE/UNASSIGNED:HbA1c is an insensitive marker for assessing real-time dysglycemia in obesity. This study investigated whether 1-h plasma glucose level (1-h PG) ≥155 mg/dL (8.6 mmol/L) during an oral glucose tolerance test (OGTT) and continuous glucose monitoring (CGM) measurement of glucose variability (GV) better reflected dysglycemia than HbA1c after weight loss from metabolic and bariatric surgery. METHODS/UNASSIGNED:This was a prospective cohort study of 10 participants with type 2 diabetes compared with 11 participants with non-diabetes undergoing sleeve gastrectomy (SG). At each research visit; before SG, and 6 weeks and 6 months post-SG, body weight, fasting lipid levels, and PG and insulin concentrations during an OGTT were analyzed. Mean amplitude of glycemic excursions (MAGE), a CGM-derived GV index, was analyzed. RESULTS/UNASSIGNED:-cell function, remained reduced in the diabetes group when compared to the non-diabetes group. CONCLUSIONS/UNASSIGNED:-cell dysfunction and the potential residual risk of diabetes complications.

PURPOSE/OBJECTIVE:We undertook a trial to test the efficacy of a technology-assisted health coaching intervention for weight management, called Goals for Eating and Moving (GEM), within primary care. METHODS:). The primary outcome (weight change at 12 months) and exploratory outcomes (eg, program attendance, diet, physical activity) were analyzed according to intention to treat. RESULTS:= .48). There were no statistically significant differences in secondary outcomes. Exploratory analyses showed that the GEM arm had a greater change than the EUC arm in mean number of weekly minutes of moderate to vigorous physical activity other than walking, a finding that may warrant further exploration. CONCLUSIONS:The GEM intervention did not achieve clinically important weight loss in primary care. Although this was a negative study possibly affected by health system resource limitations and disruptions, its findings can guide the development of similar interventions. Future studies could explore the efficacy of higher-intensity interventions and interventions that include medication and bariatric surgery options, in addition to lifestyle modification.

In 2022, 1 in 8 people in the world were living with obesity, and lifestyle interventions that include diet, exercise, and behavioral modification have been the foundation for management of obesity. Recently, pharmacologic therapies have been developed for management of obesity, the newest of these being glucagon-like peptide 1 receptor agonists. With the development of new pharmacologic options, the American Gastroenterological Association developed a guideline in 2022 to provide evidence-based recommendations for the pharmacologic management of obesity in adults and recommended, for adults with obesity or overweight with weight-related complications who have had an inadequate response to lifestyle interventions, adding pharmacologic agents to lifestyle interventions over continuing lifestyle interventions alone. In this article, 2 experts review the available evidence to answer the following questions: How effective are lifestyle interventions for the treatment of obesity? How effective are pharmacologic interventions for the treatment of obesity? Given these options, how do you engage in a shared decision-making discussion to develop a mutually agreed-on treatment plan?

Widespread pain (WP) is associated with reduced function and disability. Importantly, three-fourths of the approximately 42% of U.S. adults with obesity have WP. Moreover, rates of adult obesity are higher, and WP outcomes are worse in racialized non-Hispanic Black and Hispanic/Latino/a/X groups, potentially exacerbating existing pain disparities. Bariatric surgery significantly reduces weight and improves pain. However, recurrent or unresolved pain after bariatric surgery can hinder weight loss or facilitate weight regain. The current study conducted a secondary analysis of a longitudinal study of predictors and mechanisms of weight loss after bariatric surgery to examine the point prevalence of WP and pain trajectories 24 months post surgery. Our secondary aim was to examine the association between weight loss and pain characteristics. Our exploratory aim was to longitudinally examine racial differences in pain trajectories after bariatric surgery. Our results showed that point prevalence decreased after bariatric surgery. Additionally, significant improvements in pain trajectories occurred within the first 3 months post surgery with a pattern of pain reemergence beginning at 12 months post surgery. Hispanic/Latino/a/X participants reported a higher number of painful anatomical sites before bariatric surgery, and the rate of change in this domain for this group was faster compared with the racialized non-Hispanic Black participants. These findings suggest that pain improvements are most evident during the early stages of surgical weight loss in racialized populations of adults with WP. Thus, clinicians should routinely monitor patients' weight changes after bariatric surgery as they are likely to correspond to changes in their pain experiences. PERSPECTIVE: This article presents the prevalence and pain trajectories of racialized adults with WP after surgical weight loss. Clinicians should evaluate changes in the magnitude and spatial distribution of pain after significant weight change in these populations so that pain interventions can be prescribed with greater precision.

PURPOSE/OBJECTIVE:We developed a comprehensive sleeve gastrectomy (SG) weight loss study cohort and biorepository to uncover mechanisms, biomarkers and predictive factors of weight loss, weight maintenance and amelioration of obesity-related comorbidities. For this purpose, we collected psychosocial, anthropometric, clinical data and a variety of samples pre-surgery, intraoperatively and 1.5, 3, 12 and 24 months post-surgery. For longer-term assessment, the collection of psychosocial and anthropometric data was extended to 10 years. Here, we present in-depth characterisation of the cohort and detailed overview of study procedures as a foundation for future analyses. PARTICIPANTS/METHODS:We consented 647 participants between June 2017 and March 2020 from two bariatric surgery clinics in New York City-one major urban hospital and one private hospital. Of 355 participants who provided baseline data, 300 underwent SG. Of these, 79% are females with an average age of 38 years, 68% are Hispanic, 20% are non-Hispanic Black and 11% are non-Hispanic White. FINDINGS TO DATE/RESULTS:We collected intraoperative adipose and stomach tissues from 282 patients and biosamples (blood, urine, saliva, stool) from 245 patients at 1.5 months, 238 at 3 month, 218 at 12 months and 180 at 24 months post-surgery. We are currently collecting anthropometric and psychosocial data annually until 10 years post-surgery. Data analysis is currently underway. FUTURE PLANS/UNASSIGNED:Our future research will explore the variability in weight loss outcomes observed in our cohort, particularly among Black and Hispanic patients in comparison to their White counterparts. We will identify social determinants of health, metabolic factors and other variables that may predict weight loss success, weight maintenance and remission of obesity-related comorbidities. Additionally, we plan to leverage our biorepository for collaborative research studies. We will complete long-term follow-up data by December 2031. We plan to apply for funding to expand biosample collection through year 10 to provide insights into the mechanisms of long-term weight maintenance.

PURPOSE/OBJECTIVE:Examine associations between whether participants' were matched to their preferred financial incentive design and behavioral goal adherence in a weight management intervention. DESIGN/METHODS:Secondary quantitative analysis incorporating qualitative survey data. SETTING/METHODS:Primary care clinics in socioeconomically disadvantaged communities in New York City and Los Angeles. SUBJECTS/METHODS:668 participants (mean age 47.7 years, 81.0% female, 72.6% Hispanic) with obesity were enrolled in the Financial Incentives foR Weight Reduction (FIReWoRk) intervention. MEASURES/METHODS:We explored qualitatively participant's reasons for hypothetically choosing a behavioral goal-directed vs a weight loss outcome-based financial incentive program. Additionally, behavioral adherence to different goals was collected at the 6-month timepoint, categorized by match to preferred financial incentive design. ANALYSIS/METHODS:Logistic regression was used to examine if participants with certain demographic and higher psychosocial factors were more likely to choose goal-directed over outcome-based incentives. Additionally, logistic regression was used to test for associations between preference and behavioral adherence, using incentive type as an interaction term. RESULTS:= .025). Moderation analysis revealed that participants who preferred goal-directed and were matched to goal-directed had greater rates of behavioral adherence for program attendance and self-weighing, but not dietary tracking and physical activity tracking, compared to those who preferred outcome-based and were matched to outcome-based. CONCLUSION/CONCLUSIONS:Receiving one's preferred incentive design may not play a strong role in behavioral goal adherence during financially incentivized weight loss interventions.
