BackgroundCurrent and previous psychopathology in bariatric surgery candidates is believed to be common. Accurate prevalence estimates, however, are difficult to obtain given that bariatric surgery candidates often wish to appear psychiatrically healthy when undergoing psychiatric evaluation for approval for surgery. Also, structured diagnostic assessments have been infrequently used.MethodsThe present report concerned 199 patients enrolled in the Longitudinal Assessment of Bariatric Surgery study, who also participated in the Longitudinal Assessment of Bariatric Surgery-3 psychopathology substudy. The setting was 3 university hospitals, 1 private not-for-profit research institute, and 1 community hospital. All the patients were interviewed independently of the usual preoperative psychosocial evaluation process. The patients were explicitly informed that the data would not be shared with the surgical team unless certain high-risk behaviors, such as suicidality, that could lead to adverse perioperative outcomes were reported.ResultsMost of the patients were women (82.9%) and white (nonwhite 7.6%, Hispanic 5.0%). The median age was 46.0 years, and the median body mass index was 44.9 kg/m2. Of the 199 patients, 33.7% had ≥1 current Axis I disorder, and 68.8% had ≥1 lifetime Axis I disorder. Also, 38.7% had a lifetime history of a major depressive disorder, and 33.2% had a lifetime diagnosis of alcohol abuse or dependence. All these rates were much greater than the population-based prevalence rates obtained for this age group in the National Comorbidity Survey–Replication Study. Also, 13.1% had a lifetime diagnosis and 10.1% had a current diagnosis of a binge eating disorder.ConclusionThe current and lifetime rates of psychopathology are high in bariatric surgery candidates, and the lifetime rates of affective disorder and alcohol use disorders are particularly prominent. Finally, binge eating disorder is present in approximately 1 in 10 bariatric surgery candidates. 相似文献
OBJECTIVE: The purpose of this study was to examine the influence of the number of foods presented and the amount of food presented on overeating or binge eating behavior in obese subjects with and without binge eating disorder (BED). METHOD: Ten subjects (5 BED, 5 non-BED), male and female, aged 18-65, participated. Their body weight was > or =130% of their ideal body weight (IBW). They were evaluated in a feeding laboratory setting on four occasions when they were presented with (a) either one or two binge foods presented in (b) either two or four times the amount of their self-reported usual intake during a binge/overeating episode. Measurement included energy intake and self-recorded measures of hunger, fullness, anxiety, and depression. RESULTS: The results indicated that the number and amount of food presented influenced significantly the amount of food consumed. Although subjects with BED tended to eat more than the non-BED obese, the differences did not reach statistical significance. DISCUSSION: The results have implications for the interpretation of results obtained in feeding laboratory settings, suggesting that attention needs to be given to both the number and amount of foods presented because both variables have an impact on the amount of food eaten during overeating or binge eating episodes. 相似文献
Psychiatric disorders are not uncommon among severely obese patients who present for bariatric surgery. This paper (1) reviews the results of the published studies using the structured interviews to assess psychopathology in bariatric surgery candidates; (2) compares the prevalence rates of psychiatric disorders across these studies with the data from other population samples; and (3) assesses whether sociodemographic variables appear to affect these prevalence rates. We searched online resources, PubMed, PsychINFO and reference lists of all the relevant articles to provide an overview of evidence so far and highlight some details in the assessment and comparisons of different samples in different countries. The prevalence estimates in the non-treatment obese group did not appear to differ substantially from the general population group in the US or the Italian population samples, although they were relatively higher for the German population. However, the rates of psychopathology in the bariatric surgery candidates were considerably higher than the other two population groups in all the samples. Overall, the most common category of lifetime Axis I disorders in all the studies was affective disorders, with anxiety disorders being the most common category of current Axis I disorders. Certain demographic characteristics are also associated with higher rates of psychopathology, such as, female gender, low socioeconomic status, higher BMI. Overall, methodological and sociodemographic differences make these studies difficult to compare and these differences should be taken into account when interpreting the results. 相似文献
To examine cross-sectional associations between food insecurity and 12-month eating disorders, mood disorders, and anxiety disorders among U.S. adults.
Methods
This study used data collected between 2001 and 2003 from 2914 participants in the National Comorbidity Survey-Replication, a nationally representative sample of U.S. adults (mean age = 44.9 years; 53.4% female). Twelve-month food insecurity was assessed with a modified version of the Short Form U.S. Household Food Security Scale. Twelve-month DSM-IV diagnoses of mental disorders were based on the World Health Organization Composite International Diagnostic Interview. Modified Poisson regression models were conducted, adjusting for age, sex, race/ethnicity, education, and income-to-poverty ratio.
Results
Food insecurity was experienced by 11.1% of participants. Food insecurity was associated with greater prevalence of bulimic-spectrum eating disorders (prevalence ratio [PR] = 3.81; 95% confidence interval [CI] 2.26–6.42), mood disorders (PR = 2.53; 95% CI 1.96–3.29), and anxiety disorders (PR = 1.69; 95% CI 1.39–2.07).
Conclusion
Results indicate that food insecurity is associated with a range of internalizing mental disorders, though these findings should be confirmed with contemporary data to reflect DSM-5 diagnostic updates and the economic effects of the COVID-19 pandemic. Findings from this study emphasize the need to expand food insecurity interventions and improve access to mental health services for food-insecure populations.
OBJECTIVE: Eating disorder (ED) research is increasingly focusing on the proximal antecedents to disordered eating behavior. Such antecedents may include cognitions, environmental stimuli, social interactions, and affective states. Current ED theories suggest that the relationships between antecedents and eating behavior may be complex, including interaction associations, time-lagged effects, and associations that persist only for brief periods of time. Similarly, these theories often include the consequences of behavior-influencing variables of interest (e.g., short-term reductions in negative affect). Careful examination of such theories, however, has been limited by a reliance on data collection methods not appropriate for testing these effects. METHOD: This study examines alternative methods for data collection and analysis that overcome previously noted limitations, using data collected in several studies with eating-disordered participants. RESULTS: The development of a technique called ecological momentary assessment (EMA) allows the ongoing study of behavior in its natural context and reduces biases associated with retrospective recall. The development of technology that allows the sophisticated collection and storage of such data (e.g., palm-top computers), along with statistical procedures for analyzing hierarchically nested, repeated measures data, allow precise testing of complex theoretical models. DISCUSSION: We demonstrate several important features of this research: (1) patients are willing and able to engage in EMA studies, (2) data not possible to collect using other designs are obtainable, (3) complex theoretical models can be evaluated using these data and appropriate statistical methods, and (4) the collection and analysis of EMA data present unique difficulties to ED researchers. Finally, we endorse and provide recommendations for the use of EMA in future ED research and practice. 相似文献
