Food insecurity is linked to poorer dietary quality in prebariatric surgery patients

Food insecurity and weight-loss efforts among a nationally representative sample of US adults with higher weight

OBJECTIVE

The objective of this study was to examine the prevalence of food insecurity among a nationally representative sample of US adults who were attempting weight loss, as well as the associations of food insecurity with weight-loss strategies.

METHODS

This study included adults with BMI ≥ 25.0 kg/m2 who were intentionally trying to lose weight within the past year from the 2017 to March 2020 data cycle of the National Health and Nutrition Examination Study. Participants were categorized as either food insecure or food secure (US Food Security Survey Module), and their use of weight-loss strategies was compared using unadjusted logistic regression models and models adjusted for sociodemographics.

RESULTS

Nearly one-quarter (22.96%, n = 582) of participants were food insecure. In unadjusted models, participants with food insecurity were more likely to use unhealthy weight-loss methods (e.g., skipping meals, taking laxatives or vomiting) and less likely to use healthy methods (e.g., exercising, joining a weight-loss program; p < 0.05). In adjusted models, participants with food insecurity were less likely to join a weight-loss program and eat less sugar, candy, and sweets.

CONCLUSIONS

Food insecurity is common among US adults with higher weight who are trying to lose weight, and individuals with food insecurity are less likely to use healthy weight-loss strategies.

Associations of Food Addiction Symptomatology and Disordered Eating Behaviors in a Pre-Surgical Bariatric Population

The construct of food addiction (FA) has been highly debated in recent years particularly in the fields of disordered eating, medical weight management, and bariatric surgery. Some researchers have argued that FA symptoms are distinct, highly prevalent, and present a barrier for patients seeking medical treatment for obesity. The purpose of this study is to evaluate the cross-sectional associations between FA symptomatology, binge eating disorder (BED) and other appetitive traits, as well as dietary quality in a sample of adults with obesity seeking bariatric surgery. This post hoc analysis was conducted on a prospectively collected dataset from August 2020 to August 2022 at a single academic medical center. Descriptive statistics were used to characterize the sample. Additional analyses included: correlation coefficients, multivariable linear regression, and analysis of variance. A total of 587 patients were included in this analysis with low average scores for FA symptoms (mean: 1.48; standard deviation (SD): 2.15). Those with no BED symptoms had the lowest average FA symptoms scores (mean: 0.87; SD: 1.52) and those with both bingeing and LOCE had the highest average scores (mean: 3.35; SD: 2.81). This finding supports the hypothesis that, while related, FA and BED may represent different cognitions and behaviors.

Associations of COVID-19 Lockdowns on Eating Behaviors and Body Mass Index in Patients with a History of Bariatric Surgery: a Cross-Sectional Analysis

INTRODUCTION

Few studies have explored the impact of the COVID-19 pandemic on the eating behaviors, dietary quality, and changes in weight of postoperative bariatric surgery patients.

METHODS

A cross-sectional survey on eating behaviors and attitudes toward food was emailed or given to patients who had bariatric surgery before March 2020. Patient charts were reviewed for weight measures.

RESULTS

Seventy-five (71.43%) patients experienced weight recurrence with an average increase in body mass index (BMI) of 2.83 kg/m² (SD: 2.19). The majority of patients reported no symptoms of binge eating (n = 81, 77.14%) with 16 (15.24%) qualifying for loss of control eating (LOCE). LOCE was significantly associated with grazing behavior (p = 0.04), emotional over-eating (p = 0.001), and food responsiveness (p = 0.002). LOCE was negatively associated with dietary quality (p = 0.0009) and satiety responsiveness (p = 0.01). Grazing behavior was significantly associated with emotional over-eating (p < 0.0001) and food responsiveness (p < 0.0001) as well as negatively associated with dietary quality (p < 0.0001). Slow eating was negatively associated with grazing (p = 0.01), emotional over-eating (p = 0.003), and food responsiveness (p < 0.0001). When included in a regression model controlling for age and sex, emotional over-eating was a significant predictor of weight recurrence (β = 0.25; p = 0.04).

CONCLUSION

Our results suggest that maladaptive eating behaviors contributed to LOCE and poor dietary quality during the COVID-19 pandemic; however, slow eating may be protective against grazing, emotional over-eating, and food responsiveness.

Food insecurity, weight-based discrimination, weight self-stigma, and mental health in post-bariatric surgery patients

The United States Department of Agriculture defines food insecurity (FI) as reduced quality and variety of diet or overall reduced food intake. To date, limited research has investigated the relationship between FI, weight stigma, and bariatric surgery. The existing literature suggests that FI in bariatric surgery patients is significantly associated with being a person of color, depression, receiving Medicare or Medicaid, and higher eating disorder (ED) pathology. Research also suggests that weight stigma in bariatric surgery patients is associated with worsened weight loss outcomes. No research to our knowledge has investigated FI, internalized weight stigma, weight-based discrimination, and history of bariatric surgery in one sample. Bariatric surgery patients in this study (N = 266) reported elevated rates of FI relative to the general population, via an online questionnaire. Those with FI also reported higher rates of depression, anxiety, ED pathology, internalized weight stigma, and experiences of weight-based discrimination compared to those who were food secure. Given these findings, bariatric surgical centers should evaluate all potential patients for FI before surgery and, at the bare minimum, provide additional support before and post-surgery. The ethics of conducting bariatric surgery in those with FI who lack significant medical comorbidity also must be considered.

Psychosocial Aspects of Metabolic and Bariatric Surgeries and Endoscopic Therapies

Obesity is a prevalent progressive and relapsing disease for which there are several levels of intervention, including metabolic and bariatric surgery (MBS) and now endoscopic bariatric and metabolic therapies (EBMTs). Preoperative psychological assessment focused on cognitive status, psychiatric symptoms, eating disorders, social support, and substance use is useful in optimizing patient outcomes and minimizing risks in MBS. Very little is known about the psychosocial needs of patients seeking EBMTs, though these investigations will be forthcoming if these therapies become more widespread. As MBS and EBMT inherently alter the gastrointestinal (GI) tract, considerations for the longer-term GI functioning of the patient are relevant and should be considered and monitored.

Binge Eating Before and After Bariatric Surgery

PURPOSE OF REVIEW

The purpose is to review the state of the literature of binge eating in the context of bariatric surgery including prevalence, conceptualization, assessment, course, and related sequela throughout the perioperative continuum, particularly highlighting new advancements and future directions.

RECENT FINDINGS

Accurate assessment of binge eating in bariatric samples is essential for optimization of patient outcomes. Binge eating is less prevalent after bariatric surgery; however, prevalence rates increase over time. Most studies do not find a relationship between pre-operative binge eating and suboptimal weight outcomes after surgery. Refinement in understanding and conceptualization of post-operative binge eating is needed; new conceptualizations have proposed such a definition. Emerging constructs relevant to binge eating for bariatric patients include food addiction and food insecurity. Despite the introduction of formal diagnostic criteria for binge eating disorder, many uncertainties regarding the prevalence, course, and effects of binge eating currently exist; varied assessment methods continue to be a barrier to research on binge eating in bariatric surgery samples. Consensus on operational definitions for post-operative binge eating and best practices for assessment are areas for future consideration.

Hunger mediates the relationship between food insecurity and binge eating among bariatric surgery candidates

BACKGROUND

The food insecurity-obesity paradox suggests that people lacking access to adequately nutritious foods are more susceptible to disordered eating. However, the mechanisms underlying the relationship between food insecurity and binge eating are not well understood.

OBJECTIVES

This study sought to assess the role of eating behaviors (i.e., cognitive restraint, disinhibition, and hunger) as mediators between food insecurity and binge eating among a sample of preoperative bariatric candidates.

SETTING

University hospital in the Appalachian region of the United States.

METHODS

A total of 369 adults seeking bariatric surgery were included in this cross-sectional study. Patients completed validated measures of food insecurity and eating behaviors as part of a routine psychological evaluation prior to bariatric surgery.

RESULTS

Food insecurity was significantly related to binge eating symptoms (r[369] = .14, P < .01) and hunger (r[369] = .11, P < .05). Hunger mediated the relationship between food insecurity and binge eating (b = 1.23, standard error = .62, 95% confidence interval .08-2.54). Food insecurity was not associated with restraint (r[369] = .06, P = .27) or disinhibition (r[369] = .02, P = .69).

CONCLUSIONS

Food insecurity presents a unique pathway to binge eating that has several implications for intervention prior to bariatric surgery. Identification of food insecurity and the subsequent effects on eating behaviors is crucial to understanding the factors relevant to disordered eating prior to bariatric surgery.

The role of food and activity environment in a bariatric surgery population: impact on postoperative weight loss

BACKGROUND

Food and activity factors may have an impact on weight in the general population, but little is known about how this affects postbariatric surgery weight loss.

OBJECTIVES

To understand the impact of environmental food and activity factors on weight loss after bariatric surgery.

SETTING

A multidisciplinary integrated health system with an accredited bariatric surgery program.

METHODS

An institutional review board-approved retrospective review of patients who underwent bariatric surgery from 2001-2018 was completed. Food security, food retailers, and activity factors associated with postoperative percentage of total body weight loss (TBWL) at short-term (1-2 yr), medium-term (3-5 yr), and long-term (≥6 yr) follow-up were evaluated.

RESULTS

Overall, 1673 patients were included; 90% experienced ≥20% TBWL in the short term and 65% in the long term. No differences in mean TBWL were observed for food deserts or areas with high versus low food insecurity. Mean TBWL was significantly different for low versus high healthy food density (32.5% versus 33.4%, P = .024) and low versus high fitness facility density (32.6% versus 33.4%, P = .048) at short-term follow-up. Increased mean TBWL was observed for counties with more versus less exercise opportunities at short and medium-term follow-up (33.4% versus 32.5%, P = .025; 31.2% versus 29.7%, P = .019).

CONCLUSION

Patients experienced significant TBWL after bariatric surgery. Living in a food desert or area with high food insecurity did not significantly impact mean TBWL. Healthy food density, fitness facility density, and exercise opportunities had a short- to medium-term impact on TBWL. These data can be used to support patients to maximize the benefits of bariatric surgery.

Predictors of surgical intervention for those seeking bariatric surgery

BACKGROUND

Bariatric surgery has been found to be effective in the treatment of severe obesity. Studies have shown that the majority of eligible patients do not undergo surgery.

OBJECTIVES

It is important to identify variables that may impact patient decision making and potentially lead to the disproportionate underutilization of bariatric surgery.

SETTING

The study was conducted at one academic medical center in central Pennsylvania.

METHODS

Bariatric patients who participated in a preoperative psychological assessment from 2017 to early 2020 completed comprehensive self-report questionnaires addressing sociodemographic variables, health history, psychopathology, and eating behaviors. Body mass index was calculated based on clinical measurements of each patient at the start of the preoperative program. Sociodemographic variables and self-report instrument scores were compared between those who completed surgery and those who did not.

RESULTS

Of the 1234 participants, significant differences were found between the compared variables. All minority groups were less likely to undergo surgery than White patients. Participants reporting higher impairment were less likely to progress to surgery. Impairments across 3 behavioral eating assessments were associated with a lower likelihood of surgery.

CONCLUSION

There are multiple factors that contribute to patient progression to surgery, and ultimately whether the patient undergoes bariatric surgery. Results show a need for further investigation surrounding the sociodemographic and psychosocial variables that influence the patient's advancement to surgery. Both providers and patients could benefit from a deeper understanding of potential barriers to utilization of bariatric surgery.
