What Is Food Noise? A Conceptual Model of Food Cue Reactivity.

As GLP-1 receptor agonists, like semaglutide, emerge as effective treatments for weight management, anecdotal reports from patients and clinicians alike point to a reduction in what has been colloquially termed "food noise", as patients report experiencing less rumination and obsessive preoccupation about food. In this narrative review, we discuss concepts used in studies to investigate human eating behavior that can help elucidate and define food noise, particularly food cue reactivity. We propose a conceptual model that summarizes the main factors that have been shown to determine the magnitude of the reactivity elicited by external and internal food cues and how these factors can affect short- and long-term behavioral and clinical outcomes. By integrating key research conducted in this field, the Cue-Influencer-Reactivity-Outcome (CIRO) model of food cue reactivity provides a framework that can be used in future research to design studies and interpret findings related to food noise and food cue reactivity.

Psychometric Analysis of the Rapid Eating Assessment for Participants-Short Form to Evaluate Dietary Quality in a Pre-Surgical Bariatric Population.

Dietary quality and eating behaviors are essential to evaluating bariatric surgery candidates. The Rapid Eating Assessment for Participants-Short Form (REAP-S) is a previously validated measure of dietary quality suited for use in primary care. This study aimed to evaluate the psychometric properties of the REAP-S in a pre-surgical bariatric population. This study included data from one academic medical center from August 2020 to August 2022. Variables included socio-demographics, the REAP-S, mental health, and assessments of appetitive traits. Statistical methods included Cronbach's alpha, confirmatory factor analysis (CFA), and multivariable analyses. A total of 587 adult patients were included in this analysis. The mean score for the REAP-S was 28.32 (SD: 4.02), indicative of relatively moderate dietary quality. The internal consistency of the REAP-S was moderate, with a Cronbach's alpha of 0.65. The three-factor CFA model resulted in a comparative fit index of 0.91. Race (p = 0.01), body mass index (p = 0.01), food fussiness (p < 0.0001), food responsiveness (p = 0.005), and socially desirable responses (p = 0.003) were significantly associated with the total REAP-S score. Although the REAP-S's original purpose was to assess dietary quality within a primary care population, it shows promise for application within a bariatric surgery-seeking population.

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.

Assessment and impact of paediatric internalized weight bias: A systematic review.

BACKGROUND: Internalized weight bias (IWB) refers to an individual's belief in negative weight-related stigma. Children and adolescents are particularly vulnerable to IWB, but little is known about IWB in this population. OBJECTIVE: To conduct a systematic review to (1) identify the instruments that measure IWB among children and adolescents and (2) explore comorbid variables associated with paediatric IWB. METHODS: This systematic review was conducted in accordance with the PRISMA guidelines. Articles were pulled from Ovid and PubMED Medline, Ovid HealthStar and ProQuest PsychInfo. Studies were included if they were observational studies, addressed the topic of IWB, and included children under the age of 18. Major outcomes were collected and analysed using inductive qualitative methods. RESULTS: 24 studies met inclusion/exclusion criteria. Researchers used two main instruments to measure IWB: Weight Bias Internalization Scale and Weight Self Stigma Questionnaire. There was some variation in the response scales and wording of these instruments between studies. Outcomes with significant associations were divided into four categories: physical health (n = 4), mental health (n = 9), social functioning (n = 5), and eating behaviours (n = 8). CONCLUSIONS: IWB is significantly associated with and may contribute to maladaptive eating behaviours and adverse psychopathology in children.

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 (ß = 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.

Incidence of Substance Use Disorder Following Bariatric Surgery: A Retrospective Cohort Study.

BACKGROUND: New-onset substance use disorder (SUD) following bariatric surgery is a significant concern that is likely multi-factorial, although the etiologies are unclear. Previous studies have identified variable rates of SUD along with utilizing different methods and measures. The objective of this study is to evaluate new-onset SUD diagnoses among adults following bariatric surgery and compare these rates to those in the general population as well as those diagnosed with overweight or obesity. METHODS: Data was extracted from TriNetX Research Platform and used to build three cohorts of adults: those who had bariatric surgery (bariatric surgery cohort), those diagnosed with obesity or overweight, and a general population cohort. Rates of incident SUD were compared among these three groups. Initial encounters for all individuals were from January 1, 2018, to June 30, 2019. RESULTS: The incidence rate of SUD in patients with a history of bariatric surgery was 6.55% (n = 2523). When compared to the general population, persons who had any type of bariatric procedure had a decreased risk of new-onset SUD with an overall odds ratio (OR) [95% confidence limits (CL)] of 0.89 [0.86, 0.93]. When compared to persons with overweight or obesity, bariatric patients were less likely to develop any form of SUD (OR: 0.65 [0.62, 0.67]). CONCLUSION: While overall rates of new-onset SUD are lower among those who had bariatric surgery, they also vary by surgery and substance type. Efforts should still be made to address new-onset SUD in order to optimize the post-surgical care of patients.

Racial Differences in Bariatric Surgical Approach: a Cross-Sectional National Inpatient Sample Analysis.

PURPOSE: Although racial inequalities in referral and access to bariatric surgical care have been well reported, racial difference in the selection of surgical techniques is understudied. This study examined factors associated with the utilization of the two main bariatric surgical techniques: laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). MATERIALS AND METHODS: The National Inpatient Sample database was queried for patients who underwent elective LSG or LRYGB for the treatment of severe obesity. Chi-square tests and multivariable logistic regression assessed associations of surgical approach with patient and facility characteristics. Sensitivity analyses examined the following body mass index (BMI) subgroups: < 40.0 kg/m2, 40.0-44.9 kg/m2, 45.0-49.9 kg/m2, and ≥ 50.0 kg/m2. RESULTS: Within the final cohort (N = 86,053), 73.0% (N = 62,779) underwent LSG, and 27.0% (N = 23,274) underwent LRYGB. Patients with BMI 45.0-49.9 kg/m2 (OR = 0.85) and BMI ≥ 50.0 kg/m2 (OR = 0.80) were less likely to undergo LSG than patients with BMI 40.0-45.0 kg/m2 (all p < 0.001). However, Black (OR = 1.74) and White Hispanic patients (OR = 1.30) were more likely to undergo LSG than White non-Hispanic patients (all p < 0.005). In the BMI ≥ 50.0 kg/m2 group, Black patients were still more likely to undergo LSG compared to White non-Hispanic patients (OR = 1.69, p < 0.001), while Asians/Pacific Islanders were less likely to receive LSG than White non-Hispanic patients (OR = 0.41, p < 0.05). CONCLUSION: In this observational study, we identified racial differences in the selection of common bariatric surgical approaches across various BMI categories. Future investigations are warranted to study and to promote awareness of the racial/ethnic influence in attitudes on obesity, weight loss, financial support, and surgical risks during bariatric discussions with minorities.

Use of a brief, retrospective Comprehensive Feeding Practices Questionnaire in a bariatric-surgery seeking adult population.

Parental feeding practices in childhood have been shown to contribute to childhood eating habits, behaviors, and weight status. Less understood is the longitudinal impact of parental feeding practices on these variables in adulthood. Therefore, the aim of the present work was to validate a modified, brief, Comprehensive Feeding Practices Questionnaire (CFPQ) reformatted to account for retrospective recollections of parental feeding practices experienced in childhood among a sample of adults with obesity. Adults (n = 719, mean age = 44.3 years, mean BMI = 47.1 kg/m2) completed a modified, brief, retrospective CFPQ containing seven pre-defined subscales of the original CFPQ. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) procedures were used to evaluate survey factor structure and associations with gender, BMI, and self-reported race. An EFA derived six-factor model demonstrated better model fit and reliability than the originally proposed seven-factor model. Gender and self-reported race were not correlated with subscales of the brief, retrospective, CFPQ, while BMI was positively correlated with the Food as Reward subscale. This six-factor, brief, retrospective, CFPQ can be used to provide insight into the potential origins of individual eating behaviors, and warrants use in future work attempting to clarify the relationships between parental feeding practices and eating behaviors in adulthood.

Associations of Use of Social Media and Psychopathology and Body Image in Pre- and Post-surgical Bariatric Samples: a Cross-sectional Analysis.

PURPOSE: Interest has grown regarding the impact of social media platforms on mental health including body image and internalized weight bias (IWB) in those who have struggled with weight issues. However, few studies have addressed social media usage in bariatric patient samples. The objective of this study was to understand how the amount of time spent on social media could serve as a predictor for IWB in both pre- and post-operative bariatric patients. MATERIALS AND METHODS: Pre- and post-operative patients at one academic medical center completed self-report measures assessing patients' IWB, depression, anxiety, body dissatisfaction, sociodemographic variables, and social media usage. Data were collected from March 2019 to April 2020. Statistical methods that included correlations, logistical regression models, and ANOVA analysis were used to determine the relationship between time spent on social media and other covariates. RESULTS: A total of 148 responses were collected from the pre-surgical population, with 81 responses from the post-surgical sample. At baseline, the majority of respondents used social media for approximately 1 h per day (n = 37; 27.82%). Time spent on social media was negatively associated with age (r = - 0.24 [- 0.40, - 0.08]), and positively associated with IWB (r = 0.20 [0.02, 0.36]) and anxiety (r = 0.21 [0.01, 0.39]). In the post-operative group, only the 6-month BMI (r = 0.29 [0.05, 0.49]) was positively associated with time spent on social media. CONCLUSION: Given this study's findings, providers are encouraged to become aware of patients' use of social media, and to understand the impact social media usage can have on the mental well-being of patients.

Associations of Internalized Skin Bias With Age, Adverse Psychopathology, and Health-Related Quality of Life Among Patients With Hidradenitis Suppurativa: A Cross-sectional Analysis.

Importance: Hidradenitis suppurativa (HS) is a chronic autoinflammatory disease that is highly associated with affective disorders such as depression and anxiety. Recent studies have shown that patients with HS may also endorse high levels of internalized skin bias (ISB). This redirection of skin disease-related social stigma toward oneself may also play an important role in the associations between adverse psychopathology (eg, depression, anxiety) and health-related quality of life (HRQOL). Objectives: To evaluate the associations of ISB with other core outcomes in HS and to determine if ISB may mediate the associations between adverse psychopathological outcomes and impaired HRQOL. Design, Setting, and Participants: A cross-sectional study of adult patients with HS recruited from 1 academic medical center as well as through virtual social and recruitment networks. Eligible participants completed an online survey comprised of 4 survey instruments along with demographic and disease history information from April 1, 2021, to July 15, 2021. Main Outcomes and Measures: Measures included the Internalized Skin Bias Questionnaire (ISBQ), Burns Anxiety Inventory, the Beck Depression Inventory-II, the Hidradenitis Suppurativa Quality of Life (HiSQOL) instrument, along with demographic and disease history information. The primary outcome was HRQOL as measured by the HiSQOL. Data were analyzed in July through August 2021. Results: The survey was completed by 230 of 279 patients (82.4%; mean [SD] age, 39.2 [11.2] years; 209 [90.9%] identified as female, 203 [88.7%] as not Hispanic, 178 [77.7%] as White). Depression and anxiety were shown to be a substantial burden in this sample, with 56.5% of participants' scores qualifying for moderate or greater anxiety and 45.7% moderate or greater depression. The mean (SD) HRQOL scores were moderately high at 34.5 (16.7), indicating strong levels of impairment. There was a moderate correlation between ISBQ score and depression (r = 0.67); and fair correlations with HRQOL (r = 0.52) and anxiety (r = 0.56). Therefore, ISB appears to positively mediate the associations between depression and anxiety (estimated proportions of total effect that were mediated, 38.7% and 24.9%, respectively) and HRQOL. After controlling for age, disease severity, and disease duration, both ISB and anxiety were positive predictors of impaired HRQOL. Conclusions and Relevance: This cross-sectional study found that ISB was associated with adverse psychopathology and impaired HRQOL in patients with HS. Furthermore, ISB appears to mediate the associations of depression and anxiety with HRQOL. Future studies are needed to design interventions targeted at addressing adverse psychopathology associated with ISB and improving HRQOL and well-being for patients with HS.

The use of emotional intelligence skills in combating burnout among residency and fellowship program directors.

BACKGROUND: Current rates of burnout among physicians are alarming when compared to nonphysician U.S. workers, and numerous interventions have been introduced to mitigate the issue. However, no interventions have specifically targeted the 30% burnout rate among physician program directors. The complex and demanding role of program directors necessitates building relationships, solving crises, securing jobs for residents and maintaining well-being of trainees. The aim of this study is to investigate the impact of emotional intelligence (EQ) on burnout levels among program directors. METHODS: A cross-sectional survey was administered from May 17 to June 30, 2021 to program directors and assistant/ associate program directors at an academic medical center in south-central Pennsylvania. A self-report questionnaire was used to collect data. The survey included an open-ended question along with the Trait Emotional Intelligence Questionnaire- Short Form (TEIQue-SF), Copenhagen Burnout Inventory (CBI), and demographic questions. All data were analyzed using SAS Version 9.4. RESULTS: Of the 109 program directors and assistant/associate program directors invited in the survey, 34 (31.20%) responded. The findings indicate that there is a moderate inverse association between EQ and burnout, suggesting EQ as a protective factor against burnout. We also found that program directors who were considering leaving their position demonstrated higher levels of burnout compared to those who did not. Results from the open-ended question suggest that perceived lack of support, micromanagement, criticism, and extra duties with less payment were among the reasons program directors and associates were considering steeping down from their position. The results showed no association between EQ skills and years of practicing. CONCLUSIONS: Burnout among program directors and assistant/associate program directors is not as alarming as rates of burnout among physicians-in-training. However, despite high level of EQ skills and low burnout level, nearly 43% of program directors were considering leaving their position. Nurturing EQ skills may be useful in improving retention and reducing turnover among medical leaders.

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.

Evaluating the need for dermatological care in a postsurgical bariatric sample.

BACKGROUND: Bariatric surgery rates are increasing in tandem with obesity in the United States. patients after surgery bariatric can lose up to or more than one-third of their excess weight within the first year. This sudden loss of weight can lead to skin redundancy and increased susceptibility to dermatological issues. There is a paucity of literature addressing the issue of skin redundancy and associated factors following bariatric surgery. OBJECTIVES: To evaluate the prevalence and severity of dermatological concerns among postbariatric surgery patients and assess the impact of these issues on patients' quality of life. SETTING: Surgical Weight Loss Clinic at an academic medical center in south-central Pennsylvania. METHODS: A cross-sectional survey was administered from September 9 to November 30, 2020 to adult postoperative patients. Data were collected via self-report questionnaires with a retest issued approximately 72 hours later. The survey included questions regarding occurrences of skin disturbances and the Dermatology Life Quality Index. All analyses were conducted using SAS version 9.4. RESULTS: A total of 575 patients were invited to participate, with 103 participating and 69 completing the retest. The health questionnaire indicated that 69.6% of patients had challenges with skin rashes or irritation due to loose skin; 80.6% were interested in having skin removal surgery; and only 5.8% were referred to a dermatologist for their concerns. CONCLUSION: The presence of skin concerns was associated with impaired HRQOL among postbariatric patients. This suggests a need to further educate the bariatric interdisciplinary team to evaluate the impacts of skin pathology on postbariatric patients.

Associations of Social Desirability on Psychological Assessment Outcomes for Surgical Weight Loss Patients.

Literature regarding mental health and quality of life (QOL) in bariatric patients has reported high occurrence of psychological disturbance and suggested that patients may provide socially desirable responses during pre-surgical assessments in order to minimize the apparent presence of psychological disturbance. We sought to evaluate the associations between socially desirable responding and clinical outcomes of significance and to compare self-reported psychopathology with clinically evaluated diagnoses. Data were retrospectively analyzed for patients undergoing bariatric surgery at one academic medical center. Cross-sectional self-report measures were given to patients prior to surgery. Measures assessed psychopathology, disordered eating, quality of life, and social desirability. Statistical methods included descriptive statistics, correlations and building of univariate linear regression models. Patient psychopathology, disordered eating, and QOL self-report scores were all significantly related to social desirability. Rates of psychopathology were underreported using self-report measures when compared to clinical evaluations by a licensed psychologist. Socially desirable responding may have a significant effect on preoperative assessment of psychopathology and disordered eating of patients preparing for surgical weight loss.

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

BACKGROUND: Research exploring dietary quality patterns within bariatric populations is limited, despite the significance of eating behaviors for postoperative outcomes. Recent studies revealed associations between food insecurity and disordered eating behavior in bariatric patients; however, the relationship between food insecurity and dietary quality is not known. OBJECTIVE: To examine the association between dietary quality and levels of food security within a sample of presurgical bariatric patients. SETTING: One academic medical center in central Pennsylvania, United States of America. METHODS: Patients completed three self-report measures as part of their presurgical psychological assessment process. Food security status was measured by the United States Department of Agriculture's Food Security Module, modified for self-reports. Participants also completed the Rapid Eating Assessment for Participants, short version, which is a measure of dietary quality with scores ranging from 13-39, and the Adult Eating Behavior Questionnaire. Hierarchical multiple regressions were used to assess relationships between dietary quality and food security levels, and mediation models were built to explore associations between variables. RESULTS: Of the 197 participants, 35.5% reported high food security, while 35.0% and 29.5% reported marginal food security and food insecurity, respectively. Compared with patients with high food security, the dietary quality scores of food-insecure patients were 1.3 points lower (95% confidence interval [CI], -3.3 to .7; P = .2) of and marginally food-secure patients were 1.2 points lower (95% CI, -2.9 to .5) than those reporting high food security (P = .2). CONCLUSIONS: Our findings indicate a need for further exploration into the barriers that prebariatric patients may face when attempting to adhere to pre- and postoperative dietary requirements, particularly for those reporting marginal food security and food insecurity. Future research should target postoperative outcomes, including weight gain, weight regain, and dietary adherence, among the most economically vulnerable bariatric patients.

Development of the Weight Management Skills Questionnaire in a Prebariatric Surgery Sample.

BACKGROUND: Weight loss after bariatric surgery is largely predicted by adherence to diet and lifestyle changes. There is no validated measure of self-reported adherence to a range of behaviors including self-monitoring, portion control, healthy food choice, and awareness of hunger and satiety. OBJECTIVES: The goal of the present study was to develop and provide initial evidence for the validity of the Weight Management Skills Questionnaire, a measure of adherence to these changes, by identifying its factor structure and relating the total score and subscale scores to baseline BMI, weight change during a preoperative education program, dysregulated eating, and binge eating disorder (BED). SETTING: University hospital, USA. METHODS: Four hundred twenty-two bariatric surgery candidates responded the WMSQ and measures of eating behavior. Weight collected at the beginning, midpoint, and end of the presurgical program was used to compute percent total weight loss (%TWL) prior to surgery. Hierarchical factor analysis was used to explore the factor structure of the WMSQ while allowing the items to load onto a single general factor reflecting overall adherence to behavioral weight management. RESULTS: The WMSQ has three interpretable subfactors, with all items loading onto the general factor. All scales were unrelated to starting BMI; total score and subfactors measuring general and bariatric-specific weight management skills were associated with %TWL. The scale measuring hunger/satiety responsiveness was negatively related to dysregulated eating/BED. CONCLUSIONS: The WMSQ may be a useful tool in future research exploring the key weight management skills associated with successful weight loss before and after bariatric surgery.

Food insecurity in a pre-bariatric surgery sample: prevalence, demographics and food shopping behaviour.

OBJECTIVE: To identify the prevalence and demographic characteristics of food insecurity in a presurgical bariatric population. To date there has been no research on food insecurity in a presurgical bariatric population. DESIGN: Participants completed the ten-item adult food security survey module created by the US Department of Agriculture (USDA), with additional questions related to food shopping behaviours and perceived affordability of post-bariatric supplements. USDA scoring guidelines were used to classify participants as food secure, marginally food secure and food insecure. SETTING: Academic medical centre bariatric surgery clinic in Central Pennsylvania, USA. PARTICIPANTS: Adult bariatric surgery candidates (n 174). RESULTS: There was a prevalence of 17·8 % for food insecurity and 27·6 % for marginal food security. Food insecurity was associated with younger age, higher BMI, non-White race/ethnicity, having less than a college education, living in an urban area, receiving Medicaid/Medicare and participating in nutrition assistance programmes. Food-insecure participants endorsed food shopping behaviours that could interfere with postsurgical dietary adherence and perceived post-bariatric supplies as unaffordable or inaccessible. CONCLUSIONS: These results highlight the importance of screening bariatric surgical patients for food insecurity. Further study of this important problem within the bariatric population should address effects of food insecurity and related shopping behaviours on postsurgical outcomes and inform the development of programmes to better assist these high-risk patients.

The relationship between food insecurity and binge and night eating symptoms in prebariatric surgery patients is mediated by depressive symptoms.

BACKGROUND: Eleven percent of households in the United States experience food insecurity, which is a lack of access to adequate, desirable food for a healthy lifestyle. Although food insecurity is associated with increased risk of obesity and nonadherence to dietary management of chronic diseases such as diabetes, the correlates of food insecurity have not yet been studied in a bariatric surgery population. OBJECTIVES: To replicate, in a bariatric sample, previous findings that food insecurity is related to eating pathology and to test the hypothesis that this relationship is mediated by depressive symptoms. SETTING: University hospital, United States. METHODS: Two hundred forty bariatric surgery candidates responded to self-report measures of food insecurity and mood, night-eating, and binge-eating symptoms. The sample was 74% female and 71% white, with a mean age of 41.09 (11.84) years. Based on responses to the United States Department of Agriculture Adult Food Security Survey Model, 15.8% were categorized as food insecure and 25.8% as marginally food secure. Multiple regression models with bootstrapping for confidence interval estimates were used to explore mediation hypotheses. RESULTS: Food insecurity was positively associated with symptoms of night eating and binge eating, and these relationships were cross-sectionally mediated by depressive symptoms. CONCLUSIONS: Food insecure bariatric candidates may be at increased risk of poorer postoperative outcomes because of lack of access to needed food and the detrimental mental health impact of this lack of access.

The Adult Eating Behaviour Questionnaire in a bariatric surgery-seeking sample: Factor structure, convergent validity, and associations with BMI.

The aim of this study was to validate the Adult Eating Behaviour Questionnaire (AEBQ), a measure of food approach and avoidant traits, for use in bariatric surgery candidates. Participants were 337 bariatric surgery candidates in the Mid-Atlantic United States. Confirmatory factor analysis suggested that one item did not load onto its original factor. A 34-item, eight-factor model had better fit than a seven-factor model; dropping the Hunger factor, as previously suggested, did not improve fit. The factors had good internal consistency and showed convergent/divergent validity with an existing measure of food approach traits. The emotional overeating scale was positively correlated with BMI at programme entry, whereas the slow eating scale was negatively correlated with baseline weight. The AEBQ scales had the same pattern of intercorrelations and similar means to those of two previously published samples. The AEBQ is a valid measure of appetitive traits in bariatric candidates.
