Drunkorexia: A new term and diagnostic criteria

"There's just a lot of numbers and I just want to have a drink": The challenge of communicating the energy content of alcohol products

Various governments are considering the implementation of energy labelling on alcohol products as one element of obesity prevention policies. However, little is known about the most effective ways to communicate energy information to consumers. The aim of the present study was to explore consumers' reactions to different energy information provision formats to assist the development of effective energy labels. Nine focus groups (n = 83 participants) were conducted with Australian adults who reported drinking alcohol at least twice per month. Participants were exposed to an energy-only information label and labels displaying full nutrition information panels. A thematic analysis approach was used to identify key issues. While few participants were overtly enthusiastic about the mandatory display of energy values on alcohol products, there was general support for the provision of this information to assist those drinkers who could benefit from it. Substantial confusion was apparent as participants attempted to distil meaning from the provided information, particularly where it was expressed in terms of serving sizes and standard drinks. Full nutrition panels were particularly problematic in terms of creating a health halo due to the nil or low values for multiple nutrients listed. This was especially notable for information relating to sugar content. Overall, there appears to be inadequate public understanding of the concept of dietary energy in alcoholic beverages and the various terms used to quantify its presence, which is likely to limit the utility of mandatory energy information provision requirements unless they are accompanied by effective community education.

Az ezredfordulót követő első évtizedben vált divatossá, döntően egyetemi hallgatók körében, egy nagy kockázatú viselkedés, a drunkorexia, amely a szándékos éhezés vagy falás és hánytatás alkoholabúzussal történő kombinációja. A drunkorexia a fiatal felnőtt lakosság körében növekvő gyakoriságú, de nem kellően ismert prevalenciájú tünetegyüttes, amely jelentős fizikai, pszichológiai és szociális-egészségügyi következményekkel jár. Az éhezés és az excesszív alkoholfogyasztás kiváltotta anyagcsere-változások közötti interferencia életveszélyes állapot kialakulását okozhatja. A diagnosztikai kritériumok finomítása lehetővé teszi a pontos diagnózis felállítását. A terápia során a pszichoedukáció és a pszichoterápiás módszerek mellett a gyógyszeres kezelésnek is helye van.

Comprehensive Management of Drunkorexia: A Scoping Review of Influencing Factors and Opportunities for Intervention

BACKGROUND AND OBJECTIVES

Drunkorexia is a novel alcohol-related disorder prevalent among adolescents and young adults. Extensive research on the causes and their relationship is lacking. Identifying these aspects could improve early detection and management by healthcare professionals. The aim of this review was to identify the influencing factors of drunkorexia in adolescents and young adults, as well as the main opportunities for action by health professionals.

METHODS

A scoping review was conducted in June and July 2024 using three databases (Pubmed, Scopus, and Web of Science). A search and review protocol were established and registered in PROSPERO. The research questions were formulated in Patient, Concept, Context (PCC) formats for an adequate literature review. Original articles from January 2008 to July 2024 were included. Reviews, meta-analyses, and doctoral theses or academic texts were excluded. In the screening phase, a methodological assessment was conducted using the Joanna Briggs Institute's (JBI) critical appraisal tools to support study eligibility. Depending on the study design, different checklists were used, and cross-sectional studies that received scores of 4/8 or higher, quasi-experimental designs that obtained 5/9 or higher, and qualitative research that obtained 5/10 or higher were accepted.

RESULTS

A total of 1502 studies were initially found. After applying the inclusion/exclusion criteria, 20 studies were selected. Complications of emotion regulation, both positive and negative metacognitive beliefs, inability to effectively manage stress and anxiety, symptoms of post-traumatic stress disorder, self-discipline and self-control, or differences in social expectations are predisposing factors for drunkorexia. The management of malnutrition and dehydration is an opportunity for clinical professionals to address this problem. In addition, mental health issues can provide another opportunity to manage heavy alcohol consumption.

CONCLUSIONS

Drunkorexia must be recognized as a new disease to be addressed from a multidisciplinary perspective. In this way, increasing research on this trend would support prevention and intervention strategies. The use of digital platforms is essential for raising social awareness of this negative habit.

Unification of the food and alcohol disturbance literature: A systematic review

Food and alcohol disturbance (FAD) reflects the functional relationship between disordered eating and alcohol use. There are two motivations underlying FAD - to enhance the effects of alcohol and/or to compensate for alcohol-related calories. Yet, most FAD studies have failed to adequately measure the motives underlying these behaviors, leading to inconsistent and imprecise findings. The aim of the current systematic review was to thematically consolidate FAD research findings by motive, identify limitations of the existing literature, and highlight next steps for FAD researchers. Eighty-one publications, presenting data from 38,536 participants, were included in the current review. Prevalence rates for the caloric compensation and alcohol enhancement motives range from 5.6% - 88.7% and 4.7% - 81.7%, respectively. Alcohol use and disordered eating were the primary correlates of FAD for both motives, and alcohol-related consequences were positively associated with both FAD motives cross-sectionally. Major limitations of the literature include inconsistent operationalization and imprecise measurement of FAD. Primary recommendations include adopting the terminology of and operationalization of FAD presented here, ensuring attention to FAD motive in developing and testing research questions, and moving beyond cross-sectional studies. Findings from this review can be used to contribute to more rigorous and unified FAD research.

Relationship between college lifestyle variables, eating disorder education, and eating disorder risk

Objective: This study examined relationships between eating disorder risk (EDR), lifestyle variables (e.g., exposure to healthy eating media), and differences among male and female college students. Participants: College students (N = 323) completed survey questionnaires (Fall, 2016). Fifty-three participants retook the survey at a later time. Methods: Participants completed a survey measuring EDR using EDI-3 subscales and 10 college lifestyle variables. Female and male EDR and Time 1 and Time 2 EDR were compared. Relationships between EDR and college life-style variables were examined. Results: Exercise, fewer daily meals, less face-to-face interactions, more digital interactions, less exposure to healthy eating media, and having conversations about body image were associated with EDR risk. Male college students showed an increase in EDR over time. Conclusions: Several lifestyle factors predicted EDR in college females and males. These lifestyle factors are modifiable and may be addressed by colleges during orientation and within the campus environment.

Past body shaming experiences and food and alcohol disturbance in young adults: indirect effects via psychological distress

PURPOSE

This study investigated the associations between retrospective reports of body image victimization (i.e. body shaming) perpetrated by peers and by parents during childhood or adolescence, and food and alcohol disturbance (FAD) in young adulthood, considering the possible mediating role of psychological distress (i.e. subthreshold symptoms of anxiety and depression).

METHODS

The study involved 1624 young adults aged between 18 and 30 (69% women), who completed an online survey.

RESULTS

Our findings revealed that participants who reported more frequent body image victimization episodes during childhood and adolescence exhibited higher levels of psychological distress and, in turn, higher scores of FAD in young adulthood.

CONCLUSIONS

This result represents a novel contribution to understanding the psychological correlates of FAD in youths. Limitations and implications are discussed. Level of evidence Level V, descriptive study.

"If You Don't Eat, You Can Get Drunk Faster": A Qualitative Investigation of Food and Alcohol Disturbance (FAD) Expectancies

Background: Food and alcohol disturbance (FAD; i.e., use of any compensatory behavior within the context of a drinking episode to offset alcohol-related calories and/or enhance the effects of alcohol) is prevalent among U.S. college students and associated with negative consequences. Expectancies for anticipated outcomes of alcohol use and thinness/restriction behaviors, which comprise FAD, serve as promising targets of intervention for these behaviors individually; however, no study to date has identified or examined FAD expectancies, specifically. Objectives: The purpose of this study was to qualitatively examine the positive and negative FAD expectancies described by students experienced with FAD. Methods: Semi-structured open-ended interviews were conducted with 22 undergraduates with a lifetime history of FAD behavior (72.7% female, 77.3% white non-Hispanic, Mage=20.14). Results: Positive FAD expectancy themes included: Mood Improvement, Appearance/Weight-related Benefits, Alcohol Enhancement, and Social Approval and Connectedness. Negative FAD expectancy themes included: Reputational and Social Concerns, Negative Physical Consequences, Negative Psychological Consequences, and Cognitive and Behavioral Impairment. Conclusions: Results suggest that while there are many similarities, FAD expectancies are distinct from existing alcohol and thinness/restriction expectancies. Specifically, the Mood Improvement theme conceptualizes mood-related improvement within the context of both positive and negative reinforcement and both the Social Approval and Connectedness and Social and Reputational Consequences themes focus on the ways in which one's peers may view and interact with others. Findings lay the groundwork for identifying expectancies that underlie FAD behaviors and provide directions for future research and intervention efforts.

Drunkorexia Among a Sample of Lebanese Adults: The Role of Early Maladaptive Schemas

Background: Drunkorexia is a food and alcohol disturbance described as being a range of disordered and compensatory eating behaviors that co-occur with excessive alcohol consumption. The remarkable correlation, highlighted in the literature, between dysfunctional cognitions and both eating disorders and substance use disorders is able to emphasize that cognitive phenomena can be an intrapersonal factor linked to drunkorexia disorder. The aim of this study was to assess the correlation between early maladaptive schemas (EMSs) and drunkorexia among a sample of Lebanese adults.Method: We conducted a cross-sectional study across all the Lebanese governorates (September-December 2020; N = 258). The Drunkorexia Motives and Behaviors Scales, Drunkorexia Fails Scale, Drunkorexia during an Alcohol Consumption Event Scale, and Post-Drinking Compensation Scale were used to assess drunkorexia, whereas the Young Schema Questionnaire-Short Form three was used to measure EMSs.Results: Emotional deprivation and subjugation were significantly associated with more drunkorexia motives, whereas emotional inhibition was significantly associated with less drunkorexia motives. Failure was significantly associated with more drunkorexia behaviors. Abandonment and mistrust were significantly associated with more drunkorexia fails, whereas unrelenting standards was significantly associated with less drunkorexia fails. Subjugation was significantly associated with more drunkorexia during alcohol consumption on events. Social isolation was significantly associated with more post-drinking compensation, whereas unrelenting standards was significantly associated with less post-drinking compensation.Conclusion: Our findings showed that drunkorexia is positively associated with EMSs, delineating as well the specific relationships between dysfunctional cognitive schemas and drunkorexia's maladaptive behavioral aspects. They support the hypothesis that EMSs might play an important role in drunkorexia's development and perpetuation. This study could therefore serve healthcare professionals for the cognitive approach of patients with concomitant alcohol misuse and eating disorders while emphasizing the value of cognitive-behavioral interventions-namely schema therapy.

Food and alcohol disturbance among people who have undergone bariatric surgery

There have been numerous investigations of aberrant eating and substance abuse among patients who have undergone bariatric surgery, which affects the metabolism and the pharmacokinetics of alcohol. However, there is a dearth of literature considering the complex interplay between changes in post-surgery food and alcohol consumption. Furthermore, despite the increasing recognition of issues surrounding replacing food consumption with alcohol consumption (Food and Alcohol Disturbance [FAD]), most emerging research has focused on young adult populations. This perspective reviews and synthesizes the small but growing body of research on the interplay between food and alcohol consumption, particularly FAD, and considers its application to bariatric surgery in general. There are unique considerations for patients who have undergone bariatric surgery. Patients experience altered gastric anatomy, which affects food and alcohol metabolism, and are advised to abstain from drinking alcohol after surgery. After reviewing the available literature, this perspective highlights future directions for research and practice in bariatric surgery.

Social Anxiety and Drunkorexia Behaviors among Adolescents and Young Adults: The Moderating Role of Resilience

Background: Existing evidence showed that social anxiety represents a significant factor in eating disorders. However, to our knowledge, no prior study has examined the association between social anxiety and drunkorexia behaviors. Objectives: The present study aimed at exploring the relationship between social anxiety and drunkorexia behaviors, and investigating resilience as a moderator of this relationship. Participants were 333 adolescents and young adults aged 15-24 years (Mage=18.26, SDage= 1.55; 66% females) who completed an online survey. Results: The results indicated that drunkorexia behaviors were positively correlated to three dimensions of social anxiety; however, only fear of negative evaluation had a significant predictive effect. In addition, resilience only moderated the relationship between fear of negative evaluation and drunkorexia behaviors, such that youths reporting high fear of negative evaluation and low resilience showed greater drunkorexia behaviors, whereas youths reporting high resilience showed no correlation between fear of negative evaluation and drunkorexia behaviors. Conclusions: The findings highlight the importance of drunkorexia interventions and preventive measures aimed at strengthening youths' resilience and ability to effectively manage stress and social anxiety (i.e., fear of negative evaluation).

Food and Alcohol Disturbance in High School Adolescents: Prevalence, Characteristics and Association with Problem Drinking and Eating Disorders

Food and alcohol disturbance (FAD) is characterized by the association of alcohol use with compensatory behaviors such as restricting calories, physical activity and purging. Despite not being part of the current nosography, research has grown in the past 10 years, mostly on college students' samples. In this study, we aim to describe the prevalence, characteristics and association of FAD with problem drinking (PD) and eating disorder risk (EDR) in a sample of Italian high school students. Participants were 900 high school students (53.6% males; mean age = 16.22) that were administered standardized questionnaires. Students who screened positive for PD, EDR and both were, respectively, 17.3%, 5.9% and 1.3%. Approximately one out four students reported FAD behaviors, mostly to control weight and by restricting calories, with higher prevalence and severity among those who screened positive for PD. Purging behaviors were rare overall (15.5%), but significantly more frequent in participants who screened positive for both PD and EDR (41.7%). FAD was more strongly associated with alcohol use severity than with ED symptom severity across all subgroups. FAD behaviors appear to be common in the Italian high school population and more strongly associated with PD. Future studies should investigate FAD's impact on adolescents' functioning and possible early interventions.

Food and alcohol disturbance among US college students: a mixed methods scoping review

OBJECTIVE

Conduct a scoping review of food and alcohol disturbance (FAD) in US college students to overview the literature within this population and identify research opportunities.

METHODS

Studies (n = 39) were selected using systematic searches of databases and references. Search terms included: drunkorexia, "food and alcohol disturbance," and "compensatory behavior" AND alcohol AND eating.

RESULTS

Issues with methodological quality were noted. Most studies used quantitative methods and cross-sectional designs with small, biased samples. Terminologies, conceptualizations, and measures varied; however, 30% of studies neglected enhanced intoxication effects. Prevalence ranged from approximately 10-55%, with greater risk for women. Alcohol use and disordered eating were primary predictors. Personality, affective, and social factors are potential correlates. Alcohol-related consequences were higher for those with FAD.

CONCLUSIONS

While the literature is inconsistent and unclear, FAD appears to be common among college students and associated with negative consequences. Suggestions and considerations for future research are provided.

Examining gender and the longitudinal effect of weight conscious drinking dimensions on body mass index among a college freshman cohort

Objective: This study aims to: (1) examine gender differences for weight conscious drinking among college students accounting for the broader phenomenon (e.g. including the Alcohol Effects dimension); and (2) longitudinally examine the effect of weight conscious drinking behaviors on body mass index (BMI). Participants: United States freshmen students from eight participating universities (N= 1,149). Methods: Structural equation modeling was used to model the effect of gender on weight conscious drinking dimensions at 7-month follow-up. Results: Findings suggest a significant effect of gender on Alcohol Effects (β = -.15, SE = .05, p = .005) at 7-month follow-up among college freshmen. Weight conscious drinking dimensions predicted no significant change in BMI at 7-month follow-up among college freshmen. Conclusion: Findings contribute to weight conscious drinking theory and provide campus weight conscious drinking prevention initiatives with evidence to tailor their programming to address female tendencies to engage in compensatory strategies to enhance the psychoactive effects of alcohol.

An integrative model as a step toward increasing the awareness of eating disorders in the general population

Eating disorders (EDs) represent a contradictory chapter of clinical psychiatry, i.e., although they are associated with significant prevalence and risks in the long term (including vital risk, especially for anorexia nervosa), the therapeutic resources are minimal and based on low-quality data. Another contradiction arose in the last few decades, i.e., a variety of new EDs have been described, either by clinicians or signaled by mass media, but their systematic exploration is progressing very slowly. Entities like "food addiction," "orthorexia nervosa," or "emotional eating disorder" still require intensive exploration in order to find the most accurate diagnostic instruments, diagnosis criteria, prevalence data, vulnerability factors, and therapeutic approaches. This article is focused on integrating into a comprehensive model a variety of EDs not specified or loosely defined by the current international classifications of psychiatric disorders. This framework is intended as an instrument for stimulating clinical and epidemiological research, with potential favorable consequences for therapeutic research. The dimensional model suggested here includes four main categories that accommodate the already recognized EDs (i.e., anorexia nervosa, bulimia nervosa, and binge eating disorder) as well as ten EDs that still need intensive research to find their clinical and pathophysiological characteristics. More good-quality studies are urgently required regarding this topic, based on the mental and physical negative impact these EDs may have in the short and long term, especially in vulnerable populations (e.g., pregnant women, athletes, adolescents, etc.).

The Psychological Impact of the COVID-19 Pandemic on Alcohol Abuse and Drunkorexia Behaviors in Young Adults

The COVID-19 outbreak negatively affected young adults' psychological well-being, increasing their stress levels and symptoms of anxiety and depression, and potentially triggering health-risk behaviors. The present study was aimed at investigating the psychological impact of the COVID-19 pandemic on alcohol abuse and drunkorexia behaviors among young adults living in Italy. Participants were 370 emerging adults (63% women, 37% men; Mage = 21.00, SDage = 2.96, range: 18-30) who were recruited through an online survey between November 2021 and March 2022. Participants completed measures of alcohol abuse, drunkorexia behaviors, negative life experiences, and post-traumatic symptoms related to the COVID-19 outbreak. The results showed that the emotional impact and negative life experiences associated with the pandemic predicted both alcohol abuse and drunkorexia behaviors, albeit in different ways. Specifically, the number of negative life experiences during the pandemic and the tendency to avoid COVID-19-related negative thoughts positively predicted alcohol abuse; and the presence of intrusive thoughts associated with the pandemic significantly predicted the frequency of drunkorexia behaviors. Implications for research and clinical practice are discussed.

Weight misperception and substance use: Brazilian Study of Cardiovascular Risks in Adolescents (ERICA)

BACKGROUND

Adolescence is a crucial period for body image formation. Weight misperception is the discrepancy between individuals' body weight perception and their actual nutritional status. Both weight concerns and substance use are common among adolescents, and there is evidence of an associations between these two variables. Thus, the aim of this study was to assess the association between weight misperception and substance use (smoking and alcohol) in a national sample of normal weight Brazilian adolescents.

METHODS

Data were obtained from the Brazilian Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional, multicenter, national, school-based survey, carried out in 124 municipalities with more than 100,000 inhabitants from Brazil. The sample included adolescents aged 12-17 years, classified as normal weight by nutritional status evaluation. The following measures were collected: weight underestimation and overestimation (exposure); having tried cigarette smoking, current smoking, current alcohol consumption, binge drinking and current smoking and alcohol consumption(outcomes); macro-region, sex, type of school, and excessive screen time (confounders). The frequency of variables was calculated with 95% confidence intervals (CI). Poisson regression models were used to estimate prevalence ratios (PR).

RESULTS

In total, data from 53,447 adolescents were analyzed. Weight misperception was present in a third of the adolescents, with similar prevalence of weight underestimation and overestimation. In adolescents aged 12-14 years, weight underestimation and overestimation were associated with having tried cigarette smoking (PR: 1.18 and 1.43, respectively), current alcohol consumption (PR: 1.33 for both weight misperception categories), and binge drinking (PR: 1.96 and 2.01, respectively). Weight underestimation was associated with both having tried cigarette smoking and current alcohol consumption in boys (PR: 1.14 and 1.16, respectively) and girls (PR: 1.32 and 1.15, respectively). In girls, weight overestimation was associated with all substance use variables (PR between 1.19 and 1.41).

CONCLUSIONS

Our results showed an association between weight misperception and having tried cigarette smoking, alcohol consumption, and binge drinking in younger adolescents. In addition, weight overestimation was associated with all substance use indicators in girls. Based on our findings, interventions aimed to improve weight perception in normal weight adolescents may contribute to the reduction of substance use in this population.

Emotion regulation and drunkorexia behaviors among Lebanese adults: the indirect effects of positive and negative metacognition

BACKGROUND

Although metacognition processes are a core feature of restrictive eating and alcohol cravings and entail an individual to control both of his/her emotions and thoughts, yet, to our knowledge, a scarcity of research has examined their potential role in drunkorexia as cognitive and emotional predictors. The following study investigates the different associations between two emotion regulation strategies (i.e. emotional suppression and cognitive reappraisal) and drunkorexia behaviors in a sample of Lebanese adults, exploring the possible indirect effects of positive and negative alcohol-related metacognitions.

METHODS

This was a cross-sectional study that enrolled 335 participants (March-July 2021).

RESULTS

Higher problematic alcohol use (beta = 5.56), higher physical activity index (beta = 0.08), higher expressive suppression (beta = 0.23), higher negative metacognitive beliefs about cognitive harm due to drinking (beta = 0.75) and higher cognitive reappraisal (beta = 0.20) were significantly associated with more drunkorexic behaviors. The positive metacognitive beliefs about cognitive self-regulation significantly mediated the association between cognitive reappraisal and drunkorexia behaviors. Both the positive metacognitive beliefs about cognitive self-regulation and the negative metacognitive beliefs about the uncontrollability of drinking significantly mediated the association between expressive suppression and drunkorexia behaviors.

CONCLUSION

This study demonstrated that emotional and metacognitive processes are associated with drunkorexia, addressing as well the mediating effect between deficient emotional regulation and risky behavioral patterns. Overall, our results would speculate that the lack of emotional and cognitive assets might enhance internal distress perceived out of control, leading individuals to indulge in maladaptive behavioral patterns for managing the underlying impairment.

Drunkorexia behaviors and motives, eating attitudes and mental health in Lebanese alcohol drinkers: a path analysis model

BACKGROUND

Drunkorexia refers to limited intake of high-calorie food to avert gaining weight and the need to increase in alcohol excessive consumption. The present study aimed to check for an association between depression, anxiety, and stress with drunkorexia behaviors/motives among Lebanese adults, while evaluating the mediating role of inappropriate eating attitude in those associations.

METHODS

Two hundred and fifty-eight participants enrolled in this cross-sectional study, who filled an online survey (September-December 2020).

RESULTS

Drunkorexia behaviors were considered as the dependent variable; the path coefficients from stress to anxiety, from anxiety to eating attitudes, from eating attitudes to drunkorexia behaviors and from anxiety to drunkorexia behaviors were all significant. The indirect relationships showed that eating attitudes mediated the association between anxiety and drunkorexia behaviors. When taking the drunkorexia motives as the dependent variable, the path coefficients from stress to anxiety, from anxiety to eating attitudes, from eating attitudes to drunkorexia motives, and from anxiety to drunkorexia motives were all significant. The indirect relationships showed that eating attitudes mediated the association between anxiety and drunkorexia motives.

CONCLUSION

This study highlighted that individuals with more psychological problems (depression, anxiety, and stress) and inappropriate eating habits exhibit more drunkorexic motivations and behaviors.

Weighing the Risk: Developmental Pathways and Processes Underlying Obesity to Substance Use in Adolescence

Research on co-occurring obesity and substance use in adolescence has grown substantially in the past decade, but questions on the pathways and processes underlying co-occurrence remain. This review first synthesizes empirical findings on the relationship between obesity and substance use (e.g., alcohol, cannabis, tobacco use). Multidisciplinary theoretical frameworks referencing behavioral medicine, neuroscience, psychology, and public health are then used to inform an interdisciplinary, conceptual model focused on pathways and processes by which obesity increases risk of substance use. Recommendations for future research underscore the importance of prospective studies that encompass multiple domains of development. Recommendations for practice include family-based interventions that promote adaptive self-regulation, targeted antibullying or victimization interventions, and increased attention by health professionals on risky behavior associated with adolescent obesity.

Time Devoted to Individual, Collective, and Two-Person Sports: Its Association with Risk of Exercise Addiction and Alcohol Use Disorder

INTRODUCTION

Although sport activities have beneficial effects on health, excessive practice can lead to exercise addiction (EA), which can be associated with other addictive behaviors. However, results regarding the comorbidities between EA and alcohol use disorder (AUD) remain heterogeneous. This study aims to investigate the relationship between a proxy of AUD and different sport practices, more specifically focusing on EA.

METHODS

One thousand nine hundred eighty-five (N = 1,985) participants were recruited online and selected to represent the French adult population. Participants were asked to answer questions regarding sport activity, with the EA inventory questionnaire investigating EA, and alcohol consumption, with the CAGE questionnaire investigating a proxy of AUD (score ≥2).

RESULTS

AUD was associated with a higher risk of EA and with more time devoted to collective sports (such as football) and two-person sports (such as tennis). The risk of EA was higher for individual sports (such as running), and the risk of AUD seems to increase with the level of physical activity for collective sport but to decrease for individual sports. The type of sports partly but significantly mediated the relationship between AUD and EA.

CONCLUSIONS

Results support the hypothesis that different types of sport have different risks for EA (individual sports being more concerned) and AUD (collective sports being more concerned). Results suggest that the type of sports may be a crucial variable to understand how physical activity can be a risk factor for alcohol disorders. The social dimension of collective sports should be further investigated to facilitate preventive approaches.

An examination of the role of social comparison orientation and social norms in drunkorexia engagement

Drunkorexia is a behavior pattern marked by calorie restriction and/or compensation in relation to alcohol consumption. The aim of the present study was to examine the role of social norms (descriptive, injunctive) and social comparison orientation (SCO; global, alcohol-specific, eating disorder-related) in drunkorexia engagement. Specifically, our research aimed to examine a possible interaction between norms and SCO; we hypothesized that the relationship between social norms and drunkorexia would be moderated by SCO in that the relationship would be stronger among those elevated on SCO. Data were collected from an undergraduate sample (n = 501); participants completed the consent form and questions/questionnaires via Qualtrics. The results indicated that the predictor variables examined were correlated with overall drunkorexia engagement. In the regression models, in terms of main effects, eating disorder-related SCO emerged as the strongest predictor of the drunkorexia dimensions as well as overall drunkorexia engagement. Descriptive norms emerged as the second strongest predictor in the models. Only one interaction was identified; eating disorder-related SCO moderated the relationship between descriptive norms and the bulimia drunkorexia dimension. The simple slopes analysis indicated that descriptive norms was positively predictive of the bulimia drunkorexia dimension only among individuals with average or elevated eating disorder-related SCO. Social comparisons made regarding one's body, eating, or exercise (eating disorder-related) and social norms are potentially important targets for drunkorexia prevention and/or intervention programs. Further research is needed to better understand risk factors for drunkorexia engagement in the college population.

Traumatic stress and alcohol-related disordered eating in a college sample

The current study examined the association between posttraumatic stress symptoms and disordered eating behaviors related to alcohol consumption (i.e., "drunkorexia"). Participants: Participants were 478 undergraduate students at a university in the southeastern United States. Method: Participants completed online self-report questionnaires related to alcohol-related disordered eating and compensatory behaviors, posttraumatic stress symptoms, problematic drinking, and weight and shape concerns. Results: Results found that posttraumatic stress symptoms, body weight and shape concerns, and problematic drinking were independent predictors of alcohol-related disordered eating. Conclusion: These findings confirm previous research that symptoms of eating disorders and symptoms of problem drinking predict disordered eating patterns surrounding alcohol use and further indicate that trauma may play an important role in such behaviors. Results have implications for trauma-informed treatment for college students presenting with "drunkorexia."

Prevalence and demographic, substance use, and mental health correlates of fasting among U.S. college students

BACKGROUND

Fasting is an unhealthy behavior that has been frequently used as part of weight loss attempts. To date, little research has been conducted to determine the prevalence and substance use and mental health correlates of fasting among college students. Therefore, the aim of this study was to estimate the prevalence and associations between any (≥ 1 time) and regular (≥ 13 times) occurrences of fasting in the past 4 weeks and substance use and mental health correlates among a large sample of college students from 2016 to 2020.

METHODS

Data from four academic survey years (2016-2020; N = 8255) of the national (USA) Healthy Minds Study were analyzed. Unadjusted prevalence of any and regular fasting by survey year and gender was estimated. Multiple logistic regression analyses were conducted to estimate the associations between any and regular fasting and the demographic (age, body mass index, race/ethnicity, sexual orientation, highest parental education), substance use (cigarette use, marijuana use, other illicit drug use, alcohol use), and mental health (depression, anxiety, eating disorder symptoms, suicidal ideation, non-suicidal self-injury) correlates.

RESULTS

Any fasting in the past 4 weeks was common among both men (14.77%) and women (18.12%) and significantly increased from 2016 (10.30%) to 2020 (19.81%) only among men. Regular fasting significantly increased among both men and women from 2016 (men: 1.46%; women: 1.79%) to 2020 (men: 3.53%; women: 6.19%). Among men and women, both any and regular fasting in the past 4 weeks were associated with higher odds of all mental health symptoms, including a positive depression, anxiety, and eating disorder screen, suicidal ideation, and non-suicidal self-injury. Among women, but not men, any and regular fasting in the past 4 weeks were associated with higher odds of marijuana use and other illicit drug use (e.g., cocaine, ecstasy).

CONCLUSIONS

The results from this study underscore both the high and increasing prevalence of fasting among a national sample of college students, as well as the substance use and mental health symptoms associated with this behavior. Healthcare professionals both on and off campus should consider screening for fasting behaviors among college students and provide appropriate intervention when needed.

Food and alcohol disturbance in a broad age-range adult sample

Food and alcohol disturbance involves restricting, purging, or excessively exercising to compensate for the calories consumed from drinking alcohol, or to enhance intoxication levels. But these compensatory behaviors, colloquially termed "drunkorexia," have only been investigated in young adult samples-primarily college students-who are presumed to be at risk due to their high episodic drinking rates. Therefore, this study sought preliminary evidence that food and alcohol disturbance occurs in a broader age-range sample of adult drinkers. We recruited 253 participants aged 18 to 76 (M_age = 38.71) from Mechanical Turk. Rates of food and alcohol disturbance (measured by the Compensatory Eating Behaviors in Response to Alcohol Consumption) were high: 64% of the sample endorsed performing at least one compensatory behavior in the past three months. There were no gender differences in overall prevalence, though men were more likely than women to engage in food and alcohol disturbance to enhance intoxication levels. Drinking habits, drinking motivated by conformity, and abnormal eating attitudes were the strongest predictors of food and alcohol disturbance. However, eating attitudes were a stronger predictor of these behaviors in men than women, whilst drinking habits were a stronger predictor of these behaviors in women than men. The high prevalence of food and alcohol disturbance in our broad age-range sample, alongside the far-reaching health consequences of these behaviors, highlights the need for increased awareness in younger, middle, and older adults alike.

Exploring the association between psychological distress and drunkorexia behaviors in non-clinical adolescents: the moderating role of emotional dysregulation

PURPOSE

Although drunkorexia seems to represent a new form of eating disorder, it shares several features with traditional eating disorders. However, very little is known about the association between drunkorexia and a widely studied correlate of eating disorders, such as psychological distress and about mechanisms underlying this association. The present study aimed to investigate the relation between symptoms of anxiety and depression and drunkorexia, and to explore the role of emotional dysregulation as moderator of this relationship.

METHODS

The sample was composed of 402 adolescents (222 females, 180 males; range 15-21) who completed self-reported measures: Drunkorexia Motives and Behaviors Scale, which assesses different behaviors and motivations associated with drunkorexia, Emotional dysregulation scale from the Eating Disorder Inventory-3, reflecting difficulties regulating emotions, and Anxiety and Depression scales from the Symptom CheckList-90 Revised, assessing general signs of anxious and depressive symptoms.

RESULTS

Anxious symptomatology resulted a significant statistical predictor of drunkorexia behaviors (β = .28, p = .001). Furthermore, emotional dysregulation moderated the relation between anxiety and drunkorexia; specifically, a positive relation was found both at medium levels (β = .22, p = .007) and at higher levels of emotional dysregulation (β = .38, p = .000), whereas at lower levels of emotional dysregulation, this association became nonsignificant.

CONCLUSIONS

Findings suggest that adolescents who experience both elevated anxiety and emotional dysregulation may be more likely to turn to drunkorexia to reduce their unregulated negative affect in the absence of more adaptive emotion regulation strategies. Implications for intervention and prevention programs are discussed.

Drunkorexia and Emotion Regulation and Emotion Regulation Difficulties: The Mediating Effect of Disordered Eating Attitudes

Drunorexia refers to food calorie intake restriction to prevent weight gain and the desire to enhance the more extensive intoxicating effects of alcohol. The present study aimed to investigate the association of drunkorexia with emotion regulation as well as emotion regulation difficulties across the Lebanese population, and assess disordered eating attitudes as a potential mediator of these relationships. The cross-sectional study enrolled participants (n = 258) from all Lebanese districts. The study was performed through an online survey based on a self-designed and structured questionnaire. The Drunkorexia Motives and Behaviors Scales (DMBS), the College Life Alcohol Salience Scale (CLASS), the Difficulties in Emotion Regulation Scale (DERS-16), the Emotion Regulation Questionnaire (ERQ) and the Eating Attitudes Test (EAT-26) were used in the present study. The results showed that higher EAT-26 total scores (more disordered eating attitudes) (B = 0.16) and higher DERS-16 total score (B = 0.30) were significantly associated with more drunkorexia motives. Also, higher EAT-26 total scores (B = 0.09) and higher DERS-16 total score (B = 0.17) were significantly associated with more drunkorexia behaviors. In addition, higher EAT-26 total scores (B = 0.10) and higher DERS-26 total score (B = 0.36) were significantly associated with more drunkorexia fails. Furthermore, higher EAT-26 total scores (B = 0.07), and higher DERS-16 total score (B = 0.37) were significantly associated with more drunkorexia during an alcohol consumption event. Higher EAT-26 total scores (B = 0.09), and higher DERS-16 total score (B = 0.22) were significantly associated with more post-drinking compensation. Higher EAT-26 total scores (B = 0.21), higher DERS-16 total scores (B = 0.65) and higher emotion regulation (B = 0.33) were significantly associated with higher CLASS scores. The results showed that EAT-26 total scores partially mediated the association between DERS-16 total score and drunkorexia motives (25.20%), between DERS-16 total score and drunkorexia behaviors (25.16%), between DERS-16 total score and drunkorexia fails (106.87%), between DERS-16 total score and drunkorexia during an alcohol consumption event (11.84%), between DERS-16 total score and post-drinking compensation (22.55%), between ERQ total score and college life alcohol salience (8.35%) and between DERS-16 total score and college life alcohol salience (20.14%). This study highlighted that only emotional regulation difficulties were associated with drunkorexia, whereas emotional regulation was not significantly associated with such behavior.

Drunkorexia: Normative behavior or gateway to alcohol and eating pathology?

Drunkorexia is characterized by a group of behaviors designed to minimize caloric intake while maximizing levels of alcohol intoxication. Individuals plan and modify their diet, via skipping meals, exercising, or purging, to save calories for a night of alcohol consumption. Minimal research has examined risk factors related to drunkorexia, and little is known regarding associated problems. We used structural equation modeling to test associations between coping and enhancement motives, drive for thinness, body dissatisfaction, and disordered eating (i.e., bulimia behaviors) and drinking among an at-risk college population (N = 364). Drive for thinness and alcohol coping motives were positively associated with drunkorexia. Notably, drunkorexia was associated with alcohol-related outcomes, but not bulimia. While common risk factors are shared with eating pathology, drunkorexia appears to be a unique construct apart from bulimia behaviors. Results indicate drunkorexia behaviors may extend past normative drinking and place individuals at increased risk of alcohol-related problems. The current study contributes to greater understanding of functional models and maladaptive outcomes related to drunkorexia behaviors.

Drunkorexia: An Examination of the Role of Theory of Mind and Emotional Awareness among Adolescents

This study aimed to investigate Theory of Mind (ToM) and emotional awareness in drunkorexia, an emerging behavior characterized by calorie restriction when drinking alcohol is planned. A sample of 246 adolescents (148 females, 98 males; range 17-20) completed self-reported measures assessing drunkorexia, ToM and lack of emotional awareness. Drunkorexia was negatively correlated with ToM abilities, with reading neutral emotions, and positively with lack of emotional awareness. ToM and lack of emotional awareness were also found to predict drunkorexia. Findings highlighted that adolescents who engage in drunkorexia may have difficulties in reading others' mental states and being aware of their emotions.

Examining the role of body esteem and sensation seeking in drunkorexia behaviors

PURPOSE

The purpose of the present study was to examine the role of body esteem (BE), sensation seeking (SS), and their interaction in drunkorexia, a behavior pattern marked by calorie restriction/compensation in the context of alcohol consumption. While previous research on drunkorexia has focused on a range of variables, the present study examined two novel variables and their potential interaction: body esteem (weight, appearance) and sensation seeking.

METHODS

A sample of college students (n =488) completed the Body Esteem Scale for Adolescents and Adults, the Brief Sensation Seeking Scale, and the Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale, which measures overall drunkorexia engagement as well as four dimensions: alcohol effects, bulimia, dietary restraint and exercise, and restriction.

RESULTS

Moderated linear regression analyses indicated that SS and BE (weight, appearance) did not interact in predicting drunkorexia. Rather, only main effects were observed; SS, weight esteem (WE), and appearance esteem (AE) were significant in predicting overall drunkorexia engagement. In terms of the drunkorexia dimensions, AE was a significant predictor in the alcohol effects, dietary restraint and exercise, and restriction models. WE was significant in the dietary restraint and exercise model as well as the restriction model. SS was a significant predictor across all drunkorexia dimensions.

CONCLUSIONS

Our findings suggest that both elevated SS and lowered BE are associated with drunkorexia engagement. Implications for practice are discussed. Drunkorexia is a complex and multifaceted behavior pattern; therefore, further research is needed in this area of study.

Binge eating disorder is not predictive of alcohol abuse disorders in long-term follow-up period after Roux-en-Y gastric bypass surgery

INTRODUCTION

Some studies have shown an increase in alcohol use disorders (AUD) after Roux-en-Y gastric bypass surgery (RYGB), but its relationship with binge eating disorder (BED) has not been fully explored. The purpose of this study was to determine the prevalence of AUD and BED after RYGB and also to evaluate if BED is predictive of late postoperative occurrence of AUD or BED.

METHODS

Patients (n = 46) submitted to RYGB, in a tertiary outpatient weight management service at a Federal University of Sao Paulo, Brazil, were tested for BED and AUD using the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R) and AUDIT, respectively. BED was tested before surgery, while both disorders were evaluated with a follow-up period of 12 ± 1.6 years after RYGB.

RESULTS

No patients reported AUD before RYBP. After a mean period of 12 years from surgery, ten patients (21.7%) were diagnosed with AUD. Before surgery, BED was present in 24 patients (52.2%) and it was detected in seven out of these 24 patients (29.2%) after RYGB. Thirteen new cases of BED (28.2%) were detected after surgery; total of 20 patients (43.5%) with BED. No association was found between pre- and postsurgery BED (p = 0.148). After RYGB, four out of 24 patients (16.6%) with presurgery BED developed AUD, and no association was found between presurgery BED and postsurgery AUD (p = 0.384). Seven out of ten patients (70%) with AUD after RYGB also developed BED, but no statistical significance was found between these two disorders (p = 0.061).

CONCLUSION

The presence of BED before RYGB did not predict AUD and BED after RYGB. Nevertheless, factors involved in a possible association between BED and AUD after surgery remain to be determined.

Psychological characteristics and eating attitudes in adolescents with drunkorexia behavior: an exploratory study

PURPOSE

Drunkorexia represents an emerging phenomenon that is still understudied especially among adolescents. The present study aimed to investigate the relation between drunkorexia and psychological characteristics relevant and commonly associated with existing forms of eating disorders.

METHODS

The sample was composed of 849 adolescents (513 boys, 334 girls, 2 unknown; range 14-22) who completed a survey composed of Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale and Psychological scales of the Eating Disorders Inventory-3.

RESULTS

Our findings highlighted that drunkorexia was associated with low self-esteem, personal alienation, interoceptive deficits, emotional dysregulation, and asceticism. Hierarchical multiple regression analysis indicated that difficulties with emotion regulation and ascetic tendencies were significant predictors of drunkorexia among adolescents.

CONCLUSIONS

Our findings suggest the importance for programs preventing drunkorexia to be focused on training adolescents in using more adaptive strategies to manage emotions and accepting both emotional and physical signals without feeling guilty or threatened.

Behavioral and Neurobiological Consequences of Hedonic Feeding on Alcohol Drinking

A complex interplay of peripheral and central signaling mechanisms within the body of an organism maintains energy homeostasis. In addition, energy/food intake is modified by various external factors (e.g., palatability, food availability, social and environmental triggers). Highly palatable foods can provoke maladaptive feeding behavior, which in turn disrupts normal homeostatic regulation resulting in numerous health consequences. Furthermore, neuroendocrine peptides, traditionally considered to regulate appetite and energy homeostasis, also control the intake and reinforcing properties of alcohol and drugs of abuse. Therefore, dysregulated eating as a result of a hedonic/binge-like intake of hyper-palatable food may impact alcohol drinking behavior. Relevant in this case is the fact that eating disorders are highly comorbid with several neuropsychiatric conditions, including alcohol use disorder. The present review is intended to summarize the neurobiological and functional consequences of hedonic feeding on alcohol intake.

The association between Food and Alcohol Disturbance (FAD), race, and ethnic identity belonging

PURPOSE

A growing body of literature has established that food and alcohol disturbance (FAD: decreasing one's caloric intake in preparation for alcohol consumption) is a specific health risk that endangers health and wellbeing. Recent research on trends in FAD has revealed ethno-racial disparities. A sociological analysis is helpful to center race and examine the role of ethnic identity in reproducing health disparities. The current study is guided by theories of socialization into ideal body types by race.

METHODS

Study uses data from a cross-sectional survey conducted among college students. The sample includes White and Black American college students, ages 18-25, and uses ordinal logistic regression to test for the impact of race and ethnic identity on engagement in FAD using the Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS).

RESULTS

FAD prevalence was lower among Black Americans than among White Americans in the sample. Results from ordered logistic regression models indicate that stronger ethnic ties reduce likelihood of FAD among Black Americans but have the opposite effect among White Americans. This modification effect provides evidence that ethnic identity belonging protects against FAD for Black Americans but acts as a risk factor for FAD among White Americans.

CONCLUSIONS

Findings shed light on the documented racial disparities in FAD and weight control behavior more broadly. Ethnic identity modifies the relationship between race and FAD in our sample.
