A review of the relationships between extreme obesity, quality of life, and sexual function.

Extreme obesity is associated with significant health issues as well as substantial psychosocial burden for many individuals. Numerous studies have documented the impairments in quality of life associated with extreme obesity. Sexual behavior and functioning is an important aspect of quality of life but is frequently overlooked in research studies as well as clinical care. This paper focuses on the quality of life and sexual functioning of obese individuals with specific focus on the changes in these domains following the substantial weight losses seen after bariatric surgery.

Assessing Psychosocial Functioning of Bariatric Surgery Candidates with the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF)

BackgroundPsychological comorbidity is common in bariatric surgery candidates. Many multidisciplinary teams incorporate psychometric testing to screen for psychological factors that, if left unattended, may negatively impact surgical results. Here, we report descriptive findings and empirical correlates of Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) scales among of bariatric surgery candidates undergoing a pre-surgical psychological evaluation.MethodsThe sample consisted of male (n = 324) and female (n = 658) patients seeking bariatric surgery who were administered the MMPI-2-RF at their psychological evaluation. Psychosocial and medical variables were retrospectively coded from the patients’ medical records. These criteria included history/current mental health diagnoses and treatments, maladaptive eating behaviors/diagnoses, past/current substance use, abuse history, sleep apnea, and denial of surgery.ResultsDescriptive analyses demonstrated similar findings for male and female candidates and replicated previous reports. MMPI-2-RF scales measuring emotional dysfunction were associated with maladaptive eating patterns, a history of Major Depressive Disorder, and previous suicide attempts. Scale scores measuring behavioral dysfunction were associated with current/past substance use and previous physical abuse. MMPI-2-RF scale scores measuring somatic problems were associated with a higher BMI at the time of surgery, sleep apnea diagnosis/adherence, physical/sexual abuse history, active mood disorder, previous mental health diagnoses, and maladaptive eating patterns.ConclusionsThe MMPI-2-RF can aid in identifying a broad range of psychological comorbidity among bariatric surgery candidates. When used in conjunction with a pre-surgical psychological interview, it can aid in the assessment of psychological factors relevant to pre-surgical psychological assessment of bariatric surgery candidates.

Pilot evaluation of a substance abuse prevention group intervention for at-risk bariatric surgery candidates

BACKGROUND Concerns have been raised about an increased incidence of substance abuse after bariatric surgery. Alcohol use after surgery may be particularly problematic because of changes in pharmacokinetics leading to greater intoxication. The present study evaluated a substance abuse prevention group pilot intervention for at-risk bariatric surgery candidates. METHODS Patients with a history of substance abuse/dependence or at-risk substance use applying for weight loss surgery (WLS; N = 86) were referred to a single-session 90-minute intervention (67.4% female; 65.1% Caucasian; mean age 46.2 years; mean body mass index 48.77 kg/m(2)). The session included education about the health effects of alcohol/substances on WLS outcomes, developing alternative coping strategies, identifying warning signs of misuse, and providing treatment resources. Patients completed a preintervention and postintervention questionnaire measuring knowledge of substance use health effects, the Alcohol Use Disorders Identification Test-Consumption Items, and items on motivation for abstinence. RESULTS Patients reported a significant increase in knowledge regarding the negative effects of substance abuse after surgery (t = 42.34; P<.001). Patients also reported more healthy alternative coping strategies after the intervention (t = 18.96; P<.001). In addition, a significant number of patients reported a lower intention of consuming alcohol after surgery (χ(2) = 16.18; P<.001) and were more likely to report health reasons as motivation to abstain (χ(2) = 102.89; P< .001). CONCLUSIONS At-risk patients applying for weight loss surgery may benefit from a substance abuse prevention intervention. More research will be needed to see if such benefits can be sustained over time and if interventions affect postsurgical behaviors.

Use of the MMPI-2-RF Suicidal/Death Ideation and Substance Abuse Scales in Screening Bariatric Surgery Candidates

Bariatric surgery patients are at increased risk for suicide and lifetime substance abuse problems, and these risks are surgical contraindications. The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) has scales to screen for these risks factors, among others. We seek to evaluate the classification accuracy of the MMPI-2-RF Suicidal/Death Ideation (SUI) and Substance Abuse (SUB) scales to optimize their use in bariatric surgery settings. Data were collected from 1,311 (72.1% female; 65.5% Caucasian) bariatric surgery candidates from the Cleveland Clinic as well as 295 (94.1% female; 85.9% Caucasian) bariatric surgery candidates from a private practice in St. Paul, Minnesota. Classification accuracies were calculated at original and revised SUI and SUB interpretative cutoffs in the Cleveland Clinic sample and replicated in the St. Paul sample. Significant and meaningful classification accuracy gains were demonstrated by excluding a death ideation item from the SUI scale and lowering the interpretive cutoff on the SUB scale. Practical implications and study limitations are discussed.

Graze eating among bariatric surgery candidates: prevalence and psychosocial correlates

BACKGROUND Graze eating is defined as repetitive, unplanned eating of small amounts of food throughout the day. Little consensuses exist regarding whether graze eating, like binge eating disorder (BED), is characterized by feelings of loss of control (LOC). Furthermore, little is known about how patients who graze eat with and without LOC differ psychologically. OBJECTIVES The present study seeks to better characterize graze eating by examining differences between graze eating with LOC (+LOC) and without LOC (-LOC) among presurgical bariatric patients. SETTING A large, Midwestern academic medical center. METHODS The sample consisted of 288 adult bariatric surgery candidates (mean age 45.8, standard deviation [SD] 12.57) who underwent a presurgical psychological evaluation. Graze eating, BED, and other mental health diagnoses were evaluated using a semistructured interview. Participants were also administered the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and binge eating scale (BES). Data were collected using a retrospective chart review. RESULTS Among the 33% (n = 95) of the sample who reported preoperative graze eating, 32% (n = 30) also endorsed LOC. Graze eating, particularly with LOC, was associated with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) diagnoses of anxiety disorders and BED, and multiple measures of internalizing dysfunction on the MMPI-2-RF. CONCLUSIONS Bariatric surgery candidates who graze eat experience a greater degree of overall distress and psychopathology including anxiety and depression. The minority who experience grazing+LOC appear to have even greater risk of psychopathology. Moreover, there appears to be significant overlap with BED. Future research should explore whether these 2 maladaptive eating patterns benefit from similar treatment.

Psychological predictors of body image concerns 3 months after bariatric surgery

BACKGROUND Although studies have associated postoperative weight loss with improvement in body image dissatisfaction, some individuals continue to report body image concerns after bariatric surgery. These concerns are linked to increased depressive symptoms and decreased self-esteem in bariatric populations. OBJECTIVE This study sought to explore preoperative factors that may predict early body image concerns 3 months after bariatric surgery. SETTING Academic medical center. METHOD Data were analyzed from 229 patients evaluated for bariatric surgery who completed a 3-month postoperative psychology appointment and the Minnesota Multiphasic Personality Inventory, Second Edition, Restructured Form (MMPI-2-RF). Scales measuring depression, persecution, self-doubt, and inadequacy were examined. Medical records were reviewed for demographic characteristics, psychotropic medication usage, history of psychological treatment, and current or lifetime depression diagnosis. RESULTS Patients who preoperatively scored higher on demoralization (F [1, 227] = 35.40, P< .001), low positive emotions (F [1, 227] = 4.18, P< .05), ideas of persecution (F [1, 227] = 15.24, P< .001), self-doubt (F [1, 227] = 27.47, P< .001), and inefficacy (F [1, 227] = 21.34, P< .001) were significantly more likely to report body image concerns 3 months after bariatric surgery. Similarly, body image concerns were more common in patients with a preoperative depression diagnosis (χ(2) = 8.76, P<.01), current psychotropic medication usage (χ(2) = 7.13, P<.01), and history of outpatient therapy (χ(2) = 8.34, P<.01) and psychotropic medication (χ(2) = 9.66, P< .001). CONCLUSION Bariatric surgery candidates with psychopathology and other psychological risk factors are more likely to report body image concerns early after bariatric surgery. Future research is warranted to determine whether this association remains further out from surgery.

Depression and infertility in women seeking bariatric surgery

BACKGROUND Obesity has been associated with abnormalities in reproductive functioning and fertility in women. A number of potential mechanisms have been identified, including neuroendocrine functioning and polycystic ovarian syndrome. Associations between infertility, depression, and anxiety have been found in nonobese populations; however, the relationship between depression and infertility in women pursuing bariatric surgery has not been examined. This study sought to explore potential psychosocial correlates of infertility in a female bariatric population. METHODS Data were analyzed from female patients of childbearing age (n = 88; 70.5% Caucasian; mean age 36.2; mean education 14.3 years; mean body mass index [BMI] 47.9 kg/m(2)) psychologically evaluated for bariatric surgery. Participants were dichotomized as Infertility+(n = 43) or Infertility-(n = 45) based on a medical history self-report questionnaire. Medical records were reviewed for demographic characteristics, BMI, physical and/or sexual abuse history, psychiatric medication usage, outpatient behavioral health treatment, and psychiatric diagnoses. RESULTS Women identified as Infertility+were more likely to have been diagnosed with a depressive disorder not otherwise specified or a major depressive disorder (χ(2) = 3.71, P<.05, χ(2) = 4.33, P< .05) than Infertility-women. However, Infertility+women were less likely to be involved in outpatient behavioral health treatment (χ(2) = 5.65, P< .05) or to have a history of psychotropic medication usage (χ(2) = 4.61, P<.05). CONCLUSION Women struggling with infertility may be more psychiatrically vulnerable than other bariatric surgery candidates and less likely to have received mental health treatment. Additional research on the association between fertility, depression, behavioral health treatment, and obesity is warranted. Future research should consider whether this potential relationship changes after bariatric surgery.

Psychosocial Issues After Bariatric Surgery

This chapter reviews the literature on psychosocial issues after bariatric surgery. This chapter discusses the research in several specific areas, including depression, suicide, eating pathology, and alcohol abuse. In addition, studies examining quality of life and body image following weight loss surgery are reviewed. Behavioral and social factors potentially influencing outcomes (adherence and social support) are also summarized. Overall, this literature underscores the complex relationship between surgical and psychosocial outcomes. Further, this research highlights the value of addressing psychosocial factors before and after surgery in an attempt to enhance outcomes.
