Profiles of binge eating: the interaction of depressive symptoms, eating styles, and body mass index

Longitudinal Impact of Disordered Eating Attitudes on Depression, Anxiety, and Somatization in Young Women with Anorexia and Bulimia

Background/Objectives: Eating disorders, characterized by severe disturbances in eating behavior, are a public health concern, particularly among young women. This longitudinal study aimed to investigate the relationship between disordered eating attitudes and mental health outcomes, including depression, anxiety, and somatization, among individuals with eating disorders. Methods: A total of 471 young German women hospitalized with anorexia nervosa or bulimia nervosa participated in this study. Assessments were conducted at two points over a two-month interval using the Eating Disorder Inventory-2 (EDI-2) and the Patient Health Questionnaire. Regression analyses were performed to determine predictors of depression, anxiety, and somatization. The study controlled for socio-demographic segmentation using Sinus-Milieus, a social classification system, as a covariate. Results: Regression analyses revealed that interpersonal distrust and impulse regulation were significant predictors of subsequent depression. Impulse regulation strongly predicted subsequent anxiety, while both impulse regulation and social insecurity were strong predictors of subsequent somatization. The Neo-Ecological Milieu emerged as the most prevalent socio-demographic group (34.4% of participants). The Sinus-Milieus segmentation, however, did not significantly impact the health outcomes, suggesting consistent mental health issues across socio-demographic groups. Conclusions: This study's findings underscored the role of disordered eating attitudes in predicting mental health outcomes among young women with eating disorders. Addressing these attitudes in therapeutic settings may help mitigate symptoms of not only the primary condition but also depression, anxiety, and somatization.

Loneliness as a moderator of the association of affective symptoms and binge eating among college women

Affective symptoms (e.g., depression, anxiety, shame) are a potent risk factor for binge eating. However, less is known on the role of loneliness as a moderator of affective symptoms and binge eating. This objective of the current study was to investigate main effects and interactions of affective symptoms and loneliness in relation to binge eating in college women. A sample of 556 undergraduate women completed self-report questionnaires of affective symptoms, loneliness, and binge eating. Results revealed significant interactions between each affective symptom variable and loneliness in relation to binge eating, such that loneliness strengthened the positive association of affective symptoms and greater binge eating. The findings of this study demonstrate an important role of loneliness to binge eating among college women, especially those with underlying affective vulnerabilities. More theoretical and treatment-oriented work on the role of loneliness in binge eating is needed to understand mechanisms and interventions/preventions.

The relation between questionnaire-measured self-reported emotional eating and disordered eating behaviors: A meta-analysis of nearly three decades of research

Extensive research exists on the association between self-reported emotional eating (EE) and disordered eating (DE) behaviors. Heterogeneity exists by type (e.g., unidimensional vs. multidimensional) and valence (e.g., negative vs. positive) of self-reported EE, and no previous meta-analyses have examined the association between self-reported EE and DE behaviors. A total of 67 studies (N = 26,289; 43 reporting relations in one model, and 24 reporting relations in more than one model) met inclusion criteria; ranges for age and publication date were 18.0-61.8 years old and 1995 to 2022. Five models quantified relations between DE behaviors and 1) broad negative EE, 2) EE in response to depression, 3) EE in response to anger and anxiety, 4) EE in response to boredom, and 5) EE in response to positive emotions. Using random-effects models, pooled Cohen's d effect sizes suggested small, positive relations between DE behaviors and self-reported broad negative EE (d = 0.40, p < 0.001), EE-depression (d = 0.41, p < 0.001), EE-anger/anxiety (d = 0.35, p < 0.001), and EE-boredom (d = 0.38, p < 0.001). A significant, but very small, positive relation was observed between DE behaviors and self-reported EE-positive (d = 0.08, p = 0.01). Subgroup analyses suggested a medium, positive relation between self-reported broad negative EE and binge eating (d = 0.53, p < 0.001) and a small, positive relation between self-reported broad negative EE and dietary restraint (d = 0.20, p < 0.001). Significant heterogeneity was identified across all models except for the EE-boredom and DE behaviors model. Higher BMI, but not age, clinical status, or type of DE behavior strengthened the positive relation between self-reported broad negative EE and DE behaviors. Findings support previous research suggesting that negative and positive EE are distinct constructs, with negatively valenced EE being more closely associated with DE behaviors, especially binge eating.

Weight stigma from romantic partners: Its relations with maladaptive and adaptive coping and depressive symptoms

Social devaluation of being overweight is common in daily life, but little is known about the weight stigma in romantic relationships. The present study investigated the roles of maladaptive and adaptive coping strategies in the relation between the experience of weight stigma in romantic relationships and depressive symptoms in men and women, respectively. Analyses of gender differences and structural equation modeling yielded several findings. First, while men and women experienced similar levels of weight stigma from their romantic partners, women were more likely to use exercise avoidance, disengagement coping, and reappraisal coping strategies, and to exhibit more depressive symptoms than men. Second, men who experienced weight stigma tended to cope with it through exercise avoidance and disengagement coping, which were related to greater depressive symptoms. Men also coped with weight stigma adaptively via reappraisal coping, which was additionally associated with more positive affect. Third, the relation between the experience of weight stigma and depressive symptoms in women was only explained by using disengagement coping. These findings extend the understanding of weight stigma to a specific context and provide some insight that future interventions to reduce the impacts of weight stigma should be tailored accordingly for men and women.

Interoceptive sensibility, intuitive eating, binge, and disordered eating behavior among individuals with obesity: A comparative study with the general population

The present study assessed the links between interoceptive sensibility, binge, disordered (emotional, restrained, and external) and intuitive eating among individuals with obesity (n = 57) and normal weight (n = 29). Individuals with obesity presented lower "attention regulation," "body-listening," and "trusting" interoceptive dimensions. When age was controlled, group differences on "trusting" remained significant. Individuals with obesity showed lower intuitive eating, higher emotional, and binge eating compared to controls. Higher "body listening," "eating for physical rather than emotional reasons," and "reliance on hunger and satiety cues" predicted lower binge eating whereas "external eating" predicted higher binge eating among individuals with obesity. Eating for physical reasons and reliance on hunger and satiety had protective mediating roles in the relationship between external and binge eating in both groups. Interoceptive sensibility and intuitive eating should conjointly serve as psychotherapeutic targets for disordered eating, obesity, and weight management.

Could Gut Microbiota Composition Be a Useful Indicator of a Long-Term Dietary Pattern?

Despite the known effects of diet on gut microbiota composition, not many studies have evaluated the relationship between distinct dietary patterns and gut microbiota. The aim of our study was to determine whether gut microbiota composition could be a useful indicator of a long-term dietary pattern. We collected data from 89 subjects adhering to omnivorous, vegetarian, vegan, and low-carbohydrate, high-fat diet that were equally distributed between groups and homogenous by age, gender, and BMI. Gut microbiota composition was analyzed with a metabarcoding approach using V4 hypervariable region of the 16S rRNA gene. K-means clustering of gut microbiota at the genus level was performed and the nearest neighbor classifier was applied to predict microbiota clustering classes. Our results suggest that gut microbiota composition at the genus level is not a useful indicator of a subject's dietary pattern, with the exception of a vegan diet that is represented by a high abundance of Prevotella 9. Based on our model, a combination of 26 variables (anthropometric measurements, serum biomarkers, lifestyle factors, gastrointestinal symptoms, psychological factors, specific nutrients intake) is more important to predict an individual's microbiota composition cluster, with 91% accuracy, than the dietary intake alone. Our findings could serve to develop strategies to educate individuals about changes of some modifiable lifestyle factors, aiming to classify them into clusters with favorable health markers, independent of their dietary pattern.

The Relationship between Binge Drinking and Binge Eating in Adolescence and Youth: A Systematic Review and Meta-Analysis

Adolescence and youth are critical periods in which alcohol consumption is usually initiated, especially in the form of binge drinking. In recent years, it is increasingly common to find adolescents and young people who also present binge behaviors towards unhealthy food with the aim of alleviating their anxiety (emotional eating) and/or because of impulsive personality. Despite the social and health relevance of this issue, it remains scarcely studied and more preventive research needs to be developed. Our meta-analysis study aimed to evaluate the relationship and co-occurrence of both binge behaviors during adolescence and young adulthood to clarify the link between binge drinking and eating. Selective literature search on different online databases was performed. We identified discrete but significant results regarding the direct association between binge drinking and binge eating in correlation coefficients and odds ratio. Future research should focus on the common psychological background and motives behind these problematic behaviors owing to their clinical implications for effective prevention and treatment.

A snapshot of eating behaviors in undergraduate college students living in South Florida

Objective: To examine a) whether college students' eating behaviors are different by students' sex and/or body mass index (BMI) categories and b) the correlations between college students' eating behaviors and the degree to which they rely on internal bodily signals for food intake. Participants: Undergraduate college students 18-24 years old at a public university located in South Florida. Methods: Eligible students answered questionnaires to examine interoception, intuitive eating, and eating behaviors including emotional eating, restrained eating, cognitive restraint, external eating, and uncontrolled eating. Pearson correlation and independent t test were used (significance: p < 0.05). Results: Females reported lower interoception, intuitive eating, and higher emotional eating than males. Students with lower BMI had higher intuitive eating and lower restrained eating. Interoception was positively correlated with intuitive eating and negatively correlated with emotional, uncontrolled, restrained, and external eating. Conclusion: College students who have a better connection with their bodily signals have healthier eating behaviors and lower BMI.

Binge-eating behaviors in adolescents and young adults during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic and subsequent public health measures have resulted in a worsening of eating disorder symptoms and an increase in psychological distress. The present study examined symptoms and behaviors in adolescents and young adults with emotional eating, bingeing behaviors and binge eating disorder during the pandemic. Additionally, the study explored if individuals who experienced pandemic-related food availability and food affordability issues experienced increased binge-eating symptoms and negative feelings.

METHOD

Participants (n = 39) were a convenience sample who participated between November 2020 and January 2021 in a weight and lifestyle management program at an urban New England pediatric hospital. Participants completed online surveys that assessed (1) participant's exposure to COVID-19 related stress and binge-eating behaviors using the COVID-19 Exposure and Family Impact Survey-Adolescent and Young Adult Version (CEFIS-AYA) and the Binge Eating Scale (BES) respectively, (2) participants' and their families' ability to attain and afford food and its association with bingeing behaviors, and (3) the relationship between food availability and affordability and negative emotions.

RESULTS

Nearly half of all participants (48.7%) reported moderate to severe bingeing during the COVID-19 pandemic; those who experienced greater COVID-related stress reported more binge-eating behaviors (p = 0.03). There were no associations between indicators of food availability and affordability and binge eating or between food availability and affordability and negative feelings.

CONCLUSIONS

Higher pandemic-related stress was associated with more binge-eating behaviors among adolescents and young adults. These results underscore the need to monitor symptoms and provide treatment for these patients despite barriers to care imposed by the COVID-19 pandemic. Research and clinical care for adolescents and young adults with EDs must recognize and respond to pandemic effects across the weight and disordered eating spectrum.

The associations among psychological distress, stressors of the COVID-19 pandemic, and disinhibited eating of parents of three- to five-year-old children

Individuals' psychological distress is associated with disinhibited eating (external and emotional eating). The aim of the current study was to examine the moderating associations of COVID-19-related stress on parents' psychological distress (anxiety, hostility, depression) and external and emotional eating. One hundred and sixty U.S. parents of three- to five-year-old children (Mage = 34.08, SD = 6.76; 89 females) completed an online survey. After accounting for participant characteristics (i.e., age, BMI, sex), regression analyses showed that COVID-19 stress moderated the effects of anxiety, hostility, and depression on external eating. Additionally, findings showed that COVID-19 stress moderated hostility (but not anxiety or depression) on emotional eating. These findings suggest that unexpected stressors from the COVID-19 pandemic may exacerbate disinhibited eating among those individuals who experience psychological distress. This presents support for providing interventions that focus on healthy coping strategies and family well-being, support groups, and community resources (e.g., financial assistance) to alleviate external pressures during unprecedented times.

Eating behaviors, eating styles and body mass index during COVID-19 confinement in a college sample: a predictive model

BACKGROUND

COVID-19 confinement affected lifestyles. There is inconclusive evidence about changes in eating patterns, and there are few studies on the impact on body mass index (BMI), the occurrence of dysfunctional behaviors (binge eating, fat intake), and the predictive role of maladaptive eating styles (emotional, external, and restrained eating).

OBJECTIVES

(1) To analyze the differences in binge eating, fat intake, BMI, and maladaptive eating styles before and during COVID-19 confinement, and (2) to analyze whether maladaptive eating styles (before confinement) predicted binge eating, fat intake, and BMI during confinement.

METHODS

The sample consisted of 146 Spanish college students, divided into 104 females (71.2%; age: M = 22.20, SD = 2.97) and 42 males (28.8%; age: M = 24.74; SD = 3.53). All completed several dietary measures and BMI twice: before COVID-19 confinement (T1, November 2019) and during COVID-19 confinement (T2, April 2020).

RESULTS

BMI and maladaptive eating styles did not change in T2 (vs. T1). However, binge eating and fat intake decreased in T2. Emotional eating at T1 positively predicted BMI and binge eating at T2. External eating at T1 positively (and marginally) predicted fat intake at T2. Restrained eating at T1 positively predicted binge eating at T2, and negatively (and marginally) predicted BMI and fat intake at T2. The model explained 80.5% of the variance in BMI, 41.5% of the variance in binge eating, and 25.8% of the variance in fat intake during COVID-19 confinement.

CONCLUSIONS

The COVID-19 confinement had a positive impact on some eating behaviors. Future policies should focus part of their prevention on maladaptive eating styles to curb dysfunctional eating behaviors and BMI problems in times of stress.

Fear of COVID-19 mediates the relationship between negative emotional reactivity and emotional eating

Recent studies have highlighted high levels of emotional eating during the coronavirus (COVID‐19) pandemic, but have not satisfactorily explained these changing eating patterns. Here, we tested one potential explanatory model broadly based on a biosocial model of emotional eating. Specifically, we examined the extent to which negative emotional reactivity was associated with emotional eating, as well as the mediating role of fear of COVID‐19. A total of 474 women from Romania were asked to complete measures of emotional eating, negative emotional reactivity, and fear of COVID‐19. Mediation analysis showed that higher negative emotional reactivity was significantly and directly associated with greater emotional eating. This direct relationship was also mediated by fear of COVID‐19. These results highlight one possible route through which the ongoing COVID‐19 pandemic may have resulted in elevated rates of emotional eating, though further research is needed.

Negative urgency and central adiposity in a community sample: Moderated mediation by depressive symptoms and eating behaviors

Negative urgency - acting rashly in response to negative emotions - is a risk factor for central adiposity. We examine whether the relationship between negative urgency and waist-to-height ratio (WHtR) is mediated by eating behaviors (emotional eating, external eating, and cognitive restraint) and moderated by depressive symptom severity, factors that could be targeted to reduce risk associated with negative urgency. Using baseline data from the Nathan Kline Institute-Rockland Sample (N = 872; mean age = 42.4 years, SD = 15.3; 65% female; 27% non-White; mean body mass index = 27.9 kg/m², SD = 5.9), we conducted a series of mediation and moderated mediation analyses controlling for age, sex, race, and socioeconomic status. Overall, there was a positive association between negative urgency and WHtR. Emotional eating (ab = 0.02, SE = 0.003, 95% CI [0.02, 0.03]) and uncontrolled eating (ab = 0.008, SE = 0.002, 95% CI [0.004, 0.01]) were partial mediators of the relationship between negative urgency and WHtR, while cognitive restraint was not. In a parallel mediation model, emotional eating remained significant, while uncontrolled eating did not. Depressive symptom severity moderated the indirect effect of negative urgency on WHtR through emotional eating (b_int = -0.08, p < .001) but not the direct effect of negative urgency on WHtR. Our results indicate that emotional eating is a viable potential mechanism explaining the relationship between negative urgency and WHtR, and the indirect effect of negative urgency on WHtR through emotional eating becomes stronger as depressive symptom severity decreases.

Risk factors for binge eating severity among adolescent girls and boys. A structural equation modeling approach

OBJECTIVE

Parental bonding, low self-esteem, emotion dysregulation, and eating style are correlated with each other and are associated with binge eating among adolescents. However, no studies have yet examined all these variables simultaneously. In the current study, the independent and combined influences of such constructs on binge eating were tested with structural equation modeling.

METHOD

A sample of 973 students aged between 12 and 16 (M = 14.17, SD = 1.25) years was screened by means of self-report measures assessing parental bonding, self-esteem, emotion dysregulation, eating styles and binge eating severity.

RESULTS

Self-esteem (β = -0.205) and eating styles (emotional β = 0.313, external β = 0.133, and restrained β = 0.178) had a direct effect on binge eating severity. The model (χ²₍₂₂₎ = 57.679; RMSEA = 0.041; CFI = 0.987; TLI = 0.949; SRMR = 0.024) revealed that the paths from both maternal and paternal care and maternal overprotection to binge eating were mediated through low self-esteem, emotion dysregulation and each eating style, explaining 35% of the variance.

DISCUSSION

Findings provide support for a comprehensive theoretical-based model of risk factors for binge eating and suggest the possible mechanisms through which the quality of early parental relationships contribute to developing dysfunctional eating patterns. Treatment and prevention efforts should improve self-esteem and emphasize emotion regulation capabilities.

Two of a Kind? Mapping the Psychopathological Space between Obesity with and without Binge Eating Disorder

(1) Background: Obesity (OB) is a frequent co-morbidity in Binge Eating Disorder (BED), suggesting that both conditions share phenotypical features along a spectrum of eating-related behaviors. However, the evidence is inconsistent. This study aimed to comprehensively compare OB-BED patients against OB individuals without BED and healthy, normal-weight controls in general psychopathological features, eating-related phenotypes, and early life experiences. (2) Methods: OB-BED patients (n = 37), OB individuals (n = 50), and controls (n = 44) completed a battery of standardized questionnaires. Responses were analyzed using univariate comparisons and dimensionality reduction techniques (linear discriminant analysis, LDA). (3) Results: OB-BED patients showed the highest scores across assessments (e.g., depression, emotional and stress eating, food cravings, food addiction). OB-BED patients did not differ from OB individuals in terms of childhood traumatization or attachment styles. The LDA revealed a two-dimensional solution that distinguished controls from OB and OB-BED in terms of increasing problematic eating behaviors and attitudes, depression, and childhood adversities, as well as OB-BED from OB groups in terms of emotional eating tendencies and self-regulation impairments. (4) Conclusions: Findings support the idea of a shared spectrum of eating-related disorders but also highlight important distinctions relevant to identifying and treating BED in obese patients.

Prediction model for abnormal eating behaviour among hospital nurses: A structural equation modelling approach

BACKGROUND

Nurses are at a high risk of developing abnormal eating behaviour. However, few studies have attempted to identify the factors that influence such behaviour.

AIM

This study identifies factors that can predict abnormal eating behaviour in hospital nurses.

DESIGN

This study adopted a cross-sectional, descriptive correlational research design.

METHODS

A literature review was used to establish a hypothetical model, comprising the eight factors of shift work, job stress, depression, sleep quality, fatigue, coping strategy (active coping and passive coping) and abnormal eating behaviour. A convenience sample of 298 nurses aged less than 45 was recruited from two university hospitals, and structured questionnaire was administered between March and April 2017. The hypothesized model was tested using structural equation modelling.

RESULTS

Sleep quality and passive coping directly affect abnormal eating behaviour, which implies that poor sleep quality and increased passive coping worsens the behaviour. Shift work and depression indirectly affect abnormal eating behaviours.

CONCLUSION

Nursing managers and health policy makers should adopt strategies such as improving the shift-work pattern, providing adequate rest time after a night shift and enabling coping strategies by providing educational programs for hospital nurses.

Depression, Anxiety and Eating Disorder-Related Impairment: Moderators in Female Adolescents and Young Adults

Adolescents and young adults, particularly females, are highly vulnerable to the development of anxiety disorders, depression, and eating disorders. Comorbid anxiety disorder or depression in eating disorders are associated with greater symptom severity, poorer prognosis, and burden of illness. Nonetheless, studies on what affects the relationship between anxiety, depression, and eating disorders in female at-risk samples are scarce. Using hierarchical linear modeling, the present study examined potential moderators to explain between-person differences in the association between anxiety, depression, and eating disorder-related impairment within 12- to 25-year-old females (N = 320). High impairment in anxiety/depression was associated with more severe eating disorder symptoms. Older age as well as greater impairment in mood dysregulation, self-esteem, and perfectionism were linked to more severe eating disorder symptomatology. Whereas mood dysregulation, self-esteem, and perfectionism had no statistically significant moderating effects, younger age appeared to augment the association of anxiety/depression and eating disorder symptomatology. Preventive care in particular needs to consider age-related effects as eating disorder symptoms are associated more strongly with symptoms of anxiety and depression in early adolescence.

Eating to Cope With the COVID-19 Pandemic and Body Weight Change in Young Adults

PURPOSE

Life disruptions caused by the novel coronavirus (COVID-19) pandemic are particularly salient for young adults. Some young adults may engage in unhealthy eating practices to cope with social distancing and isolation during the pandemic, which could increase incidental weight gain. The purpose of this study was to examine the association of eating to cope with the pandemic with body weight change in young adults before versus after spread of COVID-19.

METHODS

Data included the baseline (October/2018-October/2019) and follow-up (May/2020-July/2020) assessments from an ongoing longitudinal cohort recruited from Southern California. A diverse sample of participants (54% Hispanic; age = 19.72[.47] years; N = 1,820) completed online self-report measures of weight at baseline and follow-up and were given a checklist of pandemic coping behaviors including overeating (yes/no) and eating high fat or sugary foods (yes/no) to cope with social distancing and isolation during the pandemic.

RESULTS

With and without adjusting for confounders, young adults who did versus did not report overeating to cope with the pandemic gained more weight from baseline to follow-up (5.55 vs. 2.54 lbs). Unhealthy food intake to cope with the pandemic was not associated with weight change. Baseline weight moderated the association of eating coping practices with weight change such that individuals with higher baseline weight gained more weight if they engaged in eating to cope behaviors versus not (p's≤.001).

CONCLUSIONS

Unhealthy eating behavior to cope with the pandemic and corresponding body weight increases may be occurring in young adults. Interventions to promote healthy eating practices in young adults warrant consideration for weight gain prevention during the pandemic.

Understanding the Influence of Eating Patterns on Binge Drinking: A Mediation Model

BACKGROUND

Binge drinking is an important health problem, and it has been related to binge eating and fat intake in animal models, but this relationship has not been tested in humans. The first objective of this study was to analyze whether binge eating and fat intake are related to binge drinking in a youth sample. The second objective was to analyze whether binge eating and fat intake mediate the relationship between individual factors associated with binge eating and fat intake (sex, body mass index (BMI), drive for thinness, body dissatisfaction, eating styles, impulsivity, and food addiction) and binge drinking.

METHODS

A sample of 428 undergraduate students filled out several questionnaires on binge drinking, binge eating, fat intake, drive for thinness, body dissatisfaction, eating styles, food addiction, and impulsivity.

RESULTS

Results showed an excellent model fit: χ2(25) = 30.342 (p = 0.212), comparative fit index (CFI) = 0.992, root mean squared error of approximation (RMSEA) = 0.022 [90% CI = 0.000, 0.047]. Binge eating and fat intake were positively related to binge drinking. Furthermore, emotional eating, external eating, and food addiction showed positive and statistically significant indirect relationships with binge drinking, whereas the relationship with restrained eating was negative.

CONCLUSIONS

These findings point to the need to use a broader approach in understanding and preventing binge drinking in the youth population by showing the influence of the eating pattern on this problem. This information could be helpful in preventing future behaviors and improving interventions that address health risk behaviors.

The moderating effects of mindful eating on the relationship between emotional functioning and eating styles in overweight and obese women

PURPOSE

The aim of the current study was to examine the moderating effect of mindful eating on the relationship between emotional functioning and eating styles in overweight and obese women.

METHODS

One hundred and eighty four overweight and obese adult women (BMI 30.12 ± 3.77 kg/m²) were assessed with the Difficulties in Emotion Regulation Scale, the Positive and Negative Affect Schedule, the Three Factor Eating Questionnaire and the Mindful Eating Scale.

RESULTS

Mindful eating significantly moderated several of the relationships between emotional functioning and eating styles. At all levels of mindful eating, emotion dysregulation and negative affect are both associated with greater emotional eating, but with stronger associations for high levels of mindful eating. For people low in mindful eating, both emotion dysregulation and negative affect are associated with lower restrictive eating, and neither of them are associated with uncontrolled eating. For people high in mindful eating, neither emotion dysregulation nor negative affect are associated with restrictive eating, and only negative affect is associated with greater uncontrolled eating.

CONCLUSION

When mindful eating techniques are included as part of an intervention for overweight or obese individuals, it is even more important that those interventions should also include techniques to reduce emotion dysregulation and negative affect.

Emotional disorder symptoms, anhedonia, and negative urgency as predictors of hedonic hunger in adolescents

Affect and reward are associated with unhealthy eating and weight; however, less research has examined affective predictors of hedonic hunger (i.e., extreme reward responsivity, pleasure toward, and drive for food), particularly among adolescents. Whether symptoms indicative of emotional disturbance increase risk of adverse reward-based eating-related symptoms such as hedonic hunger, is unknown. Such evidence could explain why emotional problems increase risk of eating and weight problems among adolescents, when eating-related health problems often originate. This report examined baseline emotional disorder symptoms, negative urgency (i.e., tendency to act impulsively in response to negative affect), and anhedonia (i.e., loss of interest in activities and decreased pleasure) as prospective predictors of increases in hedonic hunger in adolescents; associations between changes in emotional disturbance problems and hedonic hunger were also examined. Ninth-grade students (N = 2598) from high schools completed paper-and-pencil surveys at baseline and a 1-year follow-up. In a multivariable model controlling for the covariance of emotional problems, higher negative urgency, general anxiety, and obsessive-compulsive symptoms, and lower anhedonia at baseline independently predicted increases in hedonic hunger one year later. Also, increases in negative urgency, general anxiety, and obsessive-compulsive symptoms and decreases in anhedonia independently predicted increases in hedonic hunger. Affect- and reward-related variables may be important contributors to risk of hedonic hunger in adolescence.

Partial sleep deprivation and food intake in participants reporting binge eating symptoms and emotional eating: preliminary results of a quasi-experimental study

Sleep deprivation consistently increases food intake. This study aimed to evaluate the effect of partial sleep deprivation on food intake in individuals reporting binge eating, controlling for self-reported depressive emotional eating. Fourteen young adults reporting binge eating symptoms and 14 controls denying any eating disorders symptoms were offered a large and varied breakfast after a night of habitual sleep (HN) and after a night of partial sleep deprivation (DN). Food intake was unobtrusively measured while daily food intake was measured via a food diary. Results revealed only a significant effect of the Night on fibre consumed at breakfast and on the amount of daily snacks: both groups consumed less fibre and more snacks after DN compared to after HN. However, when controlling for depressive emotional eating, results showed that individuals reporting low depressive emotional eating ate less after DN than after HN at breakfast, but then they ate more throughout the day. Partial sleep deprivation may decrease fibre consumption and increase daily snacks regardless of binge eating symptoms, while daily food intake may increase only in individuals who do not report emotional eating.

LEVEL OF EVIDENCE

Experimental study, Level 1.

Independent and interactive associations of negative affect, restraint, and impulsivity in relation to binge eating among women

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of binge eating. In addition, a two-way interaction was found for negative affect and nonplanning impulsivity in relation to binge eating, such that nonplanning impulsivity strengthened the association between negative affect and binge eating. Attentional and nonplanning facets of impulsivity may function as an underlying trait-level risk factor interacts with affective and/or cognitive risk (e.g., negative affect, dietary restraint) factors to predict elevated binge eating.

Examining social support, rumination, and optimism in relation to binge eating among Caucasian and African-American college women

PURPOSE

Binge eating is a significant concern among college age women-both Caucasian and African-American women. Research has shown that social support, coping, and optimism are associated with engaging in fewer negative health behaviors including binge eating among college students. However, the impact of sources of social support (i.e., support from family, friends, and a special person), rumination, and optimism on binge eating as a function of race/ethnicity has received less attention. The purpose of this study was to examine the association between social support, rumination, and optimism and binge eating among Caucasian and American-American women, separately.

METHOD

Caucasian (n = 100) and African-American (n = 84) women from a university in the Mid-Atlantic US completed an online survey about eating behaviors and psychosocial health.

RESULTS

Social support from friends was associated with less likelihood of binge eating among Caucasian women. Social support from family was associated with less likelihood of binge eating among African-American women, but greater likelihood of binge eating among Caucasian women. Rumination was associated with greater likelihood of binge eating among Caucasian and African-American women. Optimism was associated with less likelihood of binge eating among African-American women.

CONCLUSIONS

These results demonstrate similarities and differences in correlates of binge eating as a function of race/ethnicity.

Evaluating the Ecological Validity of the Dutch Eating Behavior Questionnaire Among Obese Adults Using Ecological Momentary Assessment

This study evaluated the ecological validity (i.e., accurate measurement of a construct as experienced in naturalistic settings) of the self-report Dutch Eating Behavior Questionnaire (DEBQ). Obese adults (N = 50) completed the DEBQ, followed by a 2-week ecological momentary assessment protocol that included measures of eating episodes and associated intrapersonal contextual factors. Results revealed that DEBQ Emotional Eating was associated with greater negative affect and less positive affect at both pre- and post-eating episode, as well as post-eating ratings of feeling driven to eat. DEBQ External Eating was positively associated with pre-eating expectations about enjoying the taste of food, but was unrelated to actual enjoyment reported post-eating; External Eating was positively associated with the post-eating ratings of feeling driven to eat. DEBQ Dietary Restraint was positively associated with pre-eating intentions to eat less to lose/avoid gaining weight. Overall, results provide some support for the ecological validity of the DEBQ.

Association between depression and eating behaviors among bariatric surgery candidates in a Turkish sample

PURPOSE

The purpose of this study was to explore further whether depression is associated with problematic eating behaviors in a sample of Turkish bariatric surgery candidates.

METHODS

This descriptive study included 168 consecutively seen bariatric surgery candidates in a university bariatric surgery outpatient. Participants were asked to complete the Dutch Eating Behavior Questionnaire (DEBQ), the Beck Depression Inventory (BDI) and surveys assessing sociodemographic and clinical variables. Correlations and linear regression analyses were performed to evaluate the relationship between clinical and demographic variables.

RESULTS

Participants had a mean age 37.7 ± 11.3 years and BMI of 46.4 ± 6.7 kg/m² (SD = 6.7). According to BDI scores, 75.5 % of the patients had mild, moderate, or severe depressive symptomatology. Lower levels of depressive symptoms were associated with higher levels of restrictive eating (r = -0.17; p = 0.04), whereas higher levels of depressive symptoms were associated with more frequent eating in response to both internal (r = 0.3; p = 0.002) and external (r = 0.2; p = 0.04) cues. The BDI scores were significantly associated with increased external eating (ß = 0.03, p < 0.02) and emotional eating (ß = 0.03, p < 0.002) scores. BMI (β = -0.02, p = 0.02 > 0.1) was not associated with DEBQ total scores.

CONCLUSIONS

This research suggests that mild, moderate or severe depressive symptoms are observed in most of the bariatric surgical candidate patients. There is a positive correlation between severity of depression and emotional/external eating behaviors, and a negative correlation between severity of depression and restrictive eating behavior. Additional research is needed to determine whether treating depression preoperatively can assist with alleviating problematic eating behaviors.

Social appearance anxiety and dietary restraint as mediators between perfectionism and binge eating: A six month three wave longitudinal study

Binge eating is related to perfectionism and restrained eating. However, the mechanisms underlying these relationships are not well understood. It is possible that social anxiety, specifically social appearance anxiety (i.e., the fear of overall appearance evaluation), influences the relationship between binge eating, perfectionism, and dietary restraint. In the current study (N = 300 women), we tested the relationship between dietary restraint, social appearance anxiety, concern over mistakes (a component of perfectionism), and binge eating in prospective data (three time points: at baseline, at two month, and at six month follow up). We found that social appearance anxiety, dietary restraint, and concern over mistakes each predicted binge eating at baseline. Only social appearance anxiety prospectively predicted binge eating when accounting for all variables. Further, in the tested model, social appearance anxiety mediated the relationship between concern over mistakes and binge eating across six months. On the contrary, dietary restraint did not mediate the relationship between concern over mistakes and binge eating in the tested model. The finding that social appearance anxiety served as a mediator between concern over mistakes and binge eating, but that dietary restraint did not, implies that social appearance anxiety may be a more salient prospective predictor of binge eating than dietary restraint. Intervening on social appearance anxiety may be important in the treatment and prevention of binge eating.

Anxiety as a Moderator of the Relationship Between Body Image and Restrained Eating

PURPOSE

To examine three indicators of psychopathology (stress, anxiety, and depression) as potential moderators of the relationship between body image dissatisfaction (BID) and restrained, emotional, and external eating, while controlling for family-related variables (i.e., household income, living situation, and psychopathology in the family) and individual variables (i.e., body mass index, physical activity, and major life events).

DESIGN AND METHODS

A descriptive, correlational cross-sectional design was used. A sample of 894 female undergraduates aged between 18 and 25 completed a self-reported questionnaire.

FINDINGS

Moderation analyses indicated that anxiety significantly moderated the relationship between BID and restrained eating, whereas depression and stress did not.

PRACTICE IMPLICATIONS

Findings may be used in the development and implementation of education and prevention programs for disordered eating in college campuses. The usefulness of these findings for nursing practice is discussed.

Parent binge eating and depressive symptoms as predictors of attrition in a family-based treatment for pediatric obesity

BACKGROUND

Attrition is a significant problem in family-based treatment (FBT) for childhood obesity. Despite this, very few studies have examined factors associated with attrition. The current study examined parent symptoms of depression and binge eating as predictors of attrition in FBT.

METHODS

Participants included 77 parents of overweight children enrolled in FBT for childhood obesity. Data were collected at baseline and post-treatment. Binary logistic regression was used to assess associations between parent binge eating symptoms, depressive symptoms, and attrition.

RESULTS

Results showed that parent binge eating symptoms (p=0.02), but not depressive symptoms (p=0.07), were significantly associated with attrition, after controlling for parent BMI, treatment group assignment, and family income.

CONCLUSIONS

Higher reported parent binge eating symptoms were significantly related to attrition in FBT. Assessment of parent binge eating may be important in identifying families at risk for dropping out of FBT. Further, FBT may need to be adapted for families with parents who have a high level of psychopathology.
