RESUMEN
BACKGROUND: Sexual minorities have higher rates of anxiety, depression, and binge eating compared to heterosexual peers. Internalized weight bias (IWB) is also higher for sexual minorities when compared to heterosexual peers. However, research has not examined whether the relationships between IWB and anxiety, depression, and binge eating differ among heterosexual and sexual minority adults pursuing bariatric surgery. OBJECTIVES: To examine whether sexual orientation (heterosexual or sexual minority) moderated the relationships between IWB and anxiety, depression, and binge eating among adults pursuing bariatric surgery. SETTING: University hospital, United States METHODS: Participants included 811 adults who presented for bariatric surgery, 45 (5.5%) of which identified as a sexual minority. Self-reported data were collected as part of a standard preoperative psychological evaluation for surgical clearance. Three separate moderation models were run to test hypotheses. RESULTS: Sexual orientation did not moderate the association of IWB with anxiety or depression. The IWB by sexual orientation interaction was significant for binge eating (F 1856) = 4.84, P = .03, R2 = .27 such that the association between IWB and binge eating was significantly stronger for sexual minority patients (b = .54, 95% confidence interval {CI} [.36, .70]), compared to heterosexual patients (b = .33, 95% CI [.30, .38]). CONCLUSIONS: Minority stress from identifying as a sexual minority may increase vulnerability to binge eating from IWB among bariatric candidates. Future research examining the directionality of the relationship between IWB and binge eating among sexual minorities is warranted.
RESUMEN
The Brief COPE Inventory is a widely used scale that measures how a person copes with a specific situation. Despite its widespread use, the factor structure of this scale is somewhat unclear and has not been tested among patients pursuing bariatric surgery. We tested competing factor analytic models of the Brief COPE Inventory among patients pursuing bariatric surgery to identify the best fitting factor model for use in pre-surgical psychological evaluations. We also examined reliability and validity of the subscales from the best fitting model of coping. Participants included 1984 patients pursuing bariatric surgery (Mage = 42.58 years, SD = 10.89, 81.39% female). The best fitting model of the Brief COPE Inventory among patients pursuing bariatric surgery was a three-factor model including interpersonal, intrapersonal, and maladaptive coping strategies. These results were replicated in a subset of the original sample and demonstrated appropriate convergent and discriminant validity with several key outcomes. The Brief COPE Inventory can be conceptualized as a multidimensional scale assessing interpersonal coping, intrapersonal coping, and maladaptive coping among patients pursuing bariatric surgery. Future work should examine how these subscales are related to surgical outcomes among people receiving treatment for excess weight.

BACKGROUND: The relationship between coping (i.e., how a person deals with stress) and weight loss after bariatric surgery is relatively inconsistent. Anxiety and depression may contribute to the lack of consistent findings in this area. It is possible that coping, including interpersonal, intrapersonal, and maladaptive coping, predicts weight loss among individuals with higher levels of anxiety or depression but not among those with lower levels of anxiety and depression. OBJECTIVE: The aim of this study was to examine the moderating role of anxiety and depression on the association between coping and weight loss in patients 24 months after bariatric surgery. SETTING: University Hospital, West Virginia, U.S.A. METHODS: Participants included 841 patients who underwent bariatric surgery, 396 of whom had 24-month weight loss data (mean age, 43.21 yr [SD, ±11.40 yr]). We ran 3 moderation models to test whether the relationship between various coping styles and postoperative weight loss was moderated by anxiety and depression symptoms. RESULTS: There was a statistically significant interaction between anxiety and depression on the association between interpersonal coping and percent excess weight loss (%EWL). Anxiety and depression also moderated the relationship between maladaptive coping and %EWL. Anxiety and depression did not moderate the association between intrapersonal coping and %EWL, but intrapersonal coping positively predicted %EWL at 24 months after bariatric surgery. CONCLUSIONS: Maladaptive coping predicted less weight loss for patients with high levels of anxiety and/or depression. Interpersonal coping predicted more weight loss for patients with low levels of anxiety and/or depression. Clinicians should take patient levels of anxiety and depression into account when making recommendations to promote weight loss among patients pursuing bariatric surgery.

PURPOSE: Coping is related to numerous health outcomes, including weight loss. However, the relationship between coping and weight loss after bariatric surgery remains unclear. OBJECTIVES: The first objective of this study was to examine cross-sectional relationships between coping, anxiety, and depression. The second objective was to determine whether baseline anxiety and depression predicted weight loss 24 months after bariatric surgery. The final objective was to identify which aspects of coping are related to weight loss 24 months after bariatric surgery. MATERIALS AND METHODS: Participants included 1203 adults who completed a pre-surgical bariatric evaluation, including 841 patients who underwent bariatric surgery, 396 of whom had 24-month weight data. Psychological variables were collected during a pre-surgical psychological evaluation. Weight-related variables were obtained through patients' electronic medical records 24 months after surgery. RESULTS: Baseline intrapersonal coping (e.g., problem-solving, acceptance) predicted both weight loss variables at 24 months after surgery. However, baseline interpersonal and maladaptive coping were not related to weight loss. Baseline anxiety and depression similarly did not predict weight loss after surgery. CONCLUSION: Use of intrapersonal coping strategies at baseline predicted weight loss 24 months after bariatric surgery. Clinicians should assess and bolster these self-reliant coping strategies prior to surgery to improve patient outcomes.

Adverse Childhood Experiences (ACEs) have been shown to be prevalent in bariatric surgery candidates with comorbid psychological symptoms. While bariatric patients who have mental illness or a history of ACEs are less likely to lose weight, presence of a support system has been reported to mitigate ACEs' effects and to maintain long-term weight loss. The current study aims to examine the association between ACEs and psychological symptoms and the effect of potential protective factors on the association among bariatric patients. The study included a total of 199 subjects seeking bariatric surgery who completed a psychological evaluation including ACEs, psychological symptoms, and presence of support system as part of the presurgical multidisciplinary weight management consultations at a large university hospital. Multivariate regression models were used to examine the association between ACEs and psychological symptoms and potential effect of support system on the association. The study found that there is a significant association between ACEs and psychological symptoms. The study also revealed that patients who reported having a childhood supportive person were significantly associated with a lower BMI, while those who reported having adulthood supportive person showed significantly less symptoms of depression, anxiety, and binge eating. The findings have significant implications that addressing ACEs in preoperative surgical process in relation to psychological conditions and therapeutic interventions within their close environmental system will be beneficial for patients to achieve optimal surgical outcomes.
RESUMEN
BACKGROUND: Few studies have examined the adjuvant use of antiobesity medications with surgery, especially in the pre- and early postoperative periods. OBJECTIVE: Evaluate the impact of adjuvant pharmacotherapy on bariatric surgery outcomes. SETTING: University hospital, United States. METHODS: A retrospective chart review of patients receiving adjuvant pharmacotherapy for obesity treatment and bariatric surgery. Patients received pharmacotherapy either preoperatively if their body mass index was >60, or in the first or second postoperative years for suboptimal weight loss. Outcome measures included percentage of total body weight loss as well as comparison with the expected weight loss curve as determined by the Metabolic and Bariatric Surgery Risk/Benefit Calculator. RESULTS: A total of 98 patients were included in the study, with 93 (94.9%) undergoing sleeve gastrectomy and 5 (5.1%) undergoing Roux-en-Y gastric bypass surgery. During the study period, patients were prescribed phentermine and/or topiramate. At postoperative year 1, patients who received pharmacotherapy preoperatively lost 31.3% of their total body weight (TBW) compared with 25.3% TBW for patients with suboptimal weight loss who received medication in the first postoperative year, and 20.8% TBW for patients who did not receive any antiobesity medication in the first postoperative year. Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) curve for comparison, patients receiving medication preoperatively weighed 2.4% less than expected, whereas patients receiving medication during the first postoperative year weighed 4.8% higher than expected. CONCLUSION: For patients having bariatric surgery who fall below the expected MBSAQIP weight loss curve, early initiation of antiobesity medications can improve the weight loss, with preoperative pharmacotherapy having the greatest effect.

Depression and anxiety are prevalent among bariatric surgery candidates, yet little is known about the course of symptoms after surgery. This study aimed to identify how soon changes in depression and anxiety occur after surgery. A retrospective review of patients treated at a university hospital was conducted. Participants attended a presurgical psychological evaluation, completed surgery, and attended follow-up visits with bariatric medical providers (2 weeks, 6 weeks, 3 months, and 6 months postoperatively). Depression and anxiety symptoms were assessed at all time points by the Patient-Reported Outcomes Measurement Information System (PROMIS) Depression and Anxiety. Generalized estimating equations models with repeated measures by person over time were used to examine change in depression and anxiety symptoms across time. Among 27 patients, anxiety (incident rate ratio (IRR) = 0.81, p = 0.04) and depression (IRR = 0.78, p = 0.05) significantly improved both 6 weeks and 3-6 months after bariatric surgery, after controlling for education, marital status, surgery type, age, and baseline body mass index. This is the first known study to show faster improvement in anxiety compared to depression after bariatric surgery. Understanding reductions in anxiety and depression symptoms may be important for postoperative care and timing of weight maintenance interventions.
RESUMEN
BACKGROUND: Positive relationships exist between adult food insecurity and binge eating, and between adverse childhood experiences and binge eating. However, the nature of these relationships remains to be determined. OBJECTIVES: The current study sought to examine the association between binge eating and childhood abuse and/or neglect and household dysfunction and to explore whether the strength of the relationship between adverse childhood experiences and binge eating differs across levels of food insecurity in patients seeking bariatric surgery. SETTING: University Hospital in the Appalachian region of United States. METHODS: A total of 366 adults seeking bariatric surgery completed validated questionnaires as a component of a routine psychological evaluation prior to surgery. RESULTS: Only childhood experiences of abuse and/or neglect were positively related to adult binge eating, r(363) = .13, P = .011. Food insecurity moderated the relationship between adverse childhood experiences and binge eating, F(4, 358) = 242.98, P < .001, such that the relationship was stronger for individuals who endorsed the presence of both food insecurity and adverse childhood experiences (M = 15.90; standard deviation [SD] = 8.38), relative to individuals who endorsed the absence of both food insecurity and adverse childhood experiences (M = 11.19; SD = 7.91; Tukey P = .005; d = .58). CONCLUSIONS: Food insecurity strengthens the relationship between adverse childhood experiences and adult binge eating. Results suggest that healthcare providers should include assessments of both adverse childhood experiences and food insecurity to identify patients who may be at risk for disordered eating prior to surgery, as these individuals may require additional interventions to address binge eating and related factors.

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.

OBJECTIVE: Research has demonstrated that adverse childhood experiences (ACEs) were related to elevated lifetime risk of developing obesity, but the underlying mechanisms between ACEs and development of obesity are yet to be fully elucidated. The current study aims to extend exiting evidence on underlying mechanisms between ACEs and development of obesity by examining whether depressive symptom and binge eating symptom have independently significant mediating effects on the association. METHODS: The study used data from a total of 473 patients seeking bariatric surgery who completed psychological evaluation including ACEs, depressive symptom, and binge eating scale as a part of presurgical multidisciplinary weight management consultations. Mediation analyses were conducted using the PROCESS macro for SPSS to examine the research objective. RESULTS: The study found that depressive symptom uniquely mediated the relationship between ACEs and obesity, but binge eating symptom did not significantly mediate the relationship independently of depression. CONCLUSIONS: The unique role of depression in relation to childhood trauma in this study argues for more focus on a mental health intervention with bariatric patients during the preoperative period. Addressing ACEs for bariatric patients who present psychiatric symptoms during preoperative process could have potential benefits to patient care.

BACKGROUND: Though psychosocial factors are routinely examined in presurgical psychological evaluations, the predictive value of some psychosocial factors on postsurgical weight loss is still relatively unknown. Additional research examining the predictive value of psychological constructs preoperatively and long-term weight outcomes is needed to enhance the clinical utility of the presurgical psychological evaluations. OBJECTIVE: This study aimed to examine psychosocial factors as predictors of weight outcomes 30 months after bariatric surgery. SETTING: University hospital in the Appalachian region of United States. METHODS: Participants included 196 adults who underwent bariatric surgery. Psychosocial data were collected as part of a routine psychological evaluation prior to bariatric surgery. Objective weight was obtained through patients' medical records at 12, 24, and 30 months after surgery. RESULTS: Linear mixed models was used to examine presurgical psychosocial factors predicting postsurgical weight loss (n at 12 months = 153, n at 24 months = 130, n at 30 months = 92). Anxiety had a significant interaction effect with time (estimate = -.01, P = .013), indicating that higher anxiety was associated with less weight loss over time. Those with severe anxiety before surgery lost the most weight 12 months after surgery but also regained the most weight 30 months after surgery. Other predictors were not statistically significant. CONCLUSION: Anxiety assessed prior to surgery predicted reduced weight loss 30 months after bariatric surgery, after controlling for surgery type, baseline weight, sex, and age. Results highlight the importance of evaluation and treatment of anxiety in presurgical bariatric 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.

Most obesity prevalence data rely on self-report, which typically differs when compared to objectively measured height, weight, and body mass index (BMI). Given that Latino men have high rates of obesity in the United States and demonstrate greater misreporting compared to Caucasian men, examining the factors that contribute to misreporting among Latino men is warranted. This study examined BMI, Latino ethnic background (Mexican or Puerto Rican), and social desirability in relation to misreporting of BMI, as defined as the discrepancy between self-reported and measured height and weight, in Latino men. Participants were 203 adult Mexican and Puerto Rican men, average age 39.41 years, who participated in a larger study. Participants self-reported their weight and height, had their weight and height objectively measured, and completed a measure of social desirability. Measured BMI was the strongest predictor of misreporting BMI, such that the greater the participants' BMI, the greater the discrepancy in BMI (p < .001). Misreporting of BMI did not vary based on ethnic background, and measured BMI did not moderate the relationship between social desirability and misreporting of BMI. When normative error was distinguished from misreporting in post-hoc analyses, results showed that only 34.5% of participants demonstrated misreporting. Findings highlight the importance of identifying normative error when examining misreporting in order to improve the accuracy of self-reported BMI data. Future research on misreporting for Latino men should include weight awareness, acculturation, and length of U.S. residency as these variables may be related to self-reported weight and height.

BACKGROUND AND AIMS: High-resolution anorectal manometry (HRM) is associated with significant patient and parent anxiety, which can impact the success and efficiency of the procedure. The nature of HRM necessitates cooperation of an alert child. This study examined effects of psychoeducation intervention on decreasing procedural distress in both pediatric patients and their parents. METHODS: A prospective randomized study of children aged 3-12 years, undergoing HRM, was performed utilizing child-centric educational video. Patients received either psychological preparation intervention or treatment-as-usual. Distress was assessed through self-reported and parent-reported anxiety measures (STAIC-S; STAI-S), physiological arousal measurements, and an observational scale of procedural distress (PBCL). RESULTS: A total of 63 children, aged 3-12 yrs (6.7 ± 2.5), completed the study. Measures of observed and reported distress and anxiety (PBCL; STAIC-S) were significantly less in children receiving intervention. Parents of children in the intervention group also reported significantly less preprocedural anxiety (STAI-S). Effects on physiological arousal were mixed, with significant preprocedural decrease in systolic blood pressure but no difference in heart rate from baseline. CONCLUSIONS: Preprocedural psychological preparation was effective in decreasing pediatric patient and parental self-reported anxiety associated with HRM. Intervention decreased physician time necessary to successfully complete the study and significantly decreased the number of times patients had to endure balloon inflation.
RESUMEN
BACKGROUND: Among adults with diabetes, 19-34% will develop a diabetic foot ulcer (DFU), which increases amputation risk and health care costs, and worsens quality of life. Regular physical activity, when increased gradually, may help prevent DFUs. In this mixed-methods study, we examined the feasibility of a low-intensity, technology-based behavioral intervention to increase activity in adults at risk for DFUs. METHOD: Participants at risk for a DFU (n = 12; 66% female; mean age = 59.9 years) received four in-person exercise and behavioral counseling sessions over 2-3 weeks, supplemented with use of an activity monitor (to track steps) and text messages (to reinforce behavioral strategies) for an added 8 weeks. Pre- and postintervention assessments of accelerometer measured activity, daily mobility, and glycemic control (A1C) were completed. Treatment acceptability was assessed by questionnaire and via key informant interview. RESULTS: The program appears feasible since all but one participant attended all four sessions, all used the activity monitor and all responded to text messages. Treatment acceptability (scale: 1 = very dissatisfied, 5 = extremely satisfied) was high; average item ratings were 4.79 (SD = 0.24). Participants increased their steps by an average of 881.89 steps/day (d = 0.66). A1C decreased on average by 0.33% (d = 0.23). Daily mobility did not change. Interview results suggest that participants perceived benefits from the intervention. Participant recommended improvements included providing more physical activity information, addressing pain, and intervention delivery in a podiatry clinic. CONCLUSION: Individuals at risk for a DFU might benefit from a minimally intensive, technology-based intervention to increase their physical activity. Future research comparing the intervention to usual care is warranted.

OBJECTIVES: Active videogames (AVGs) could provide a novel approach to increasing physical activity and decreasing sedentary activity in children, but little is known about which children are likely to use AVGs. This study examined whether youth demographics, social support, and AVG engagement influence use of AVGs and physical activity. MATERIALS AND METHODS: A diverse sample of youth participants (42.4% non-Hispanic white), aged 8-14 years (n = 85), who owned an AVG console, completed surveys, wore an activity monitor, and logged AVG use for 1 week. Regression analyses were used to examine variables associated with daily AVG minutes and to examine the relationship between daily AVG minutes and daily steps. RESULTS: Older and non-Hispanic white children played AVGs for fewer minutes per day (P's < 0.03). Greater peer support for playing AVGs was associated with greater daily AVG minutes (P = 0.003). Daily AVG minutes were not associated with daily steps. CONCLUSIONS: Results suggest that younger children and children who do not identify as non-Hispanic white may be more open to playing AVGs. Targeting social support in AVG interventions may increase time spent playing AVGs.

OBJECTIVE: The Make Better Choices 1 trial demonstrated that participants with unhealthy diet and activity behaviors who were randomized to increase fruits/vegetables and decrease sedentary leisure achieved greater diet and activity improvement than those randomized to change other pairs of eating and activity behaviors. Participants randomized to decrease saturated fat and increase physical activity achieved the least diet-activity improvement. This study examined which psychological mechanisms mediated the effects of the study treatments on healthy behavior change. METHODS: Participants (n = 204) were randomized to 1 of 4 treatments: increase fruits/vegetables and physical activity; decrease saturated fat and sedentary leisure; decrease saturated fat and increase physical activity; increase fruits/vegetables and decrease sedentary leisure. Treatments provided 3 weeks of remote coaching supported by mobile decision support technology and financial incentives. Mediational analyses were performed to examine whether changes in positive and negative affect, and self-efficacy, stages of readiness to change, liking, craving and attentional bias for fruit/vegetable intake, saturated fat intake, physical activity, and sedentary leisure explained the impact of the treatments on diet-activity improvement. RESULTS: Greater diet-activity improvement in those randomized to increase fruits/vegetables and decrease sedentary leisure was mediated by increased self-efficacy (indirect effect estimate = 0.04; 95% bias corrected CI, 0.003-0.11). All treatments improved craving, stage of change and positive affect. CONCLUSION: Accomplishing healthy lifestyle changes for 3 weeks improves positive affect, increases cravings for healthy foods and activities, and enhances readiness to make healthy behavior changes. Maximal diet and activity improvement occurs when interventions enhance self-efficacy to make multiple healthy behavior changes. (PsycINFO Database Record
