Gender differences in the associations among body mass index, weight loss, exercise, and drinking among college students

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).

Health, health behaviors, and medical care utilization among college students with obesity

Objective: The study assessed perceived health, health behaviors and conditions, and medical care utilization among students of different weight categories. Participants: Participants were college students (n = 37,583) from 58 institutions who responded to a national survey of student health behaviors. Methods: Chi-squared and mixed model analyses were completed. Results: Compared to healthy weight students, those with obesity were less likely to report excellent health and meet dietary and physical activity recommendations, and more likely to have obesity-related chronic conditions and to have attended a medical appointment in the prior 12 months. Students with obesity (84%) and overweight (70%) were more likely to be attempting weight loss compared to students of healthy weight (35%). Conclusions: Students with obesity have poorer health and health behaviors relative to students of healthy weight; students with overweight were in between. Adapting and implementing evidence-based weight management programs within colleges/universities may be beneficial for student health.

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.

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.

Differences between preemptive and non-preemptive physical activity among 'drunkorexia'-positive college students

Objective: 'Drunkorexia' is characterized by compensating for alcohol-related calories using physical activity (PA). Drunkorexia is common on college campuses but little is known about the PA behaviors within the drunkorexia paradigm. Methods: First-year college students living on campus completed an online survey collecting drunkorexia, PA, and alcohol consumption data. A total of 127 participants reported engaging in drunkorexia behaviors. Results: Fifty-three participants were classified as preemptively physically active (e.g., PA and drink on Tuesday) compared to 74 as non-preemptively physically active. Preemptively physically active participants consumed more alcohol on Fridays and Saturdays than those non-preemptively physically active. Preemptively physically active participants engaged in significantly greater amounts PA. Females accounted for all significant differences between groups. Discussion: Among drunkorexia-positive participants, many made preemptive efforts to control their calories before consuming alcohol, which may predispose them to higher incidences of adverse outcomes such as alcohol poisoning, unwanted sexual advances, and death.

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.

Food and alcohol disturbance among young adults during the COVID-19 lockdown in Italy: risk and protective factors

PURPOSE

The COVID-19 lockdown measures have had a significant impact on risk behaviors as alcohol use and disordered eating. However, little is known about a serious health-risk-behavior named "food and alcohol disturbance" (FAD), characterized by engaging in dysfunctional eating on days of planned alcohol consumption. The aim of the present study was to investigate potential factors that may have put young adults at risk or protected against FAD during the COVID-19 lockdown.

METHODS

A sample of 447 young adults (280 females, 167 males; range 18-26) completed an online survey during the country's nationwide lockdown composed of self-reported measures assessing FAD behaviors, alcohol consumption, compensatory behaviors, eating and weight concerns, social support, emotion regulation strategies, and living arrangement.

RESULTS

Our findings showed that FAD was significantly and positively correlated to alcohol consumption, use of laxatives, self-induced vomiting, eating and weight concerns, and expressive suppression, and negatively correlated to social support and living with family. Hierarchical regression analysis revealed that alcohol consumption, eating concern, and expression suppression positively predicted FAD, while social support and living with family were negative predictors.

CONCLUSIONS

Our results suggest that during the COVID-19 lockdown, preoccupation with eating and the use of expressive suppression may have increased vulnerability to FAD; conversely, perceived social support and living with family may have been a source of protection against this dysfunctional behavior.

Associations between Impulsivity and Exercise Addiction, Disordered Eating, and Alcohol Use Behaviors: A Latent Profile Analysis

BackgroundDespite the known negative consequences of exercise addiction and preliminary evidence suggesting that it may co-occur with other health risk behaviors, no studies to date have examined exercise addiction among college students in conjunction with disordered eating behaviors and alcohol use. The aim of this study was to describe which college students are most at-risk for co-occurring health risk behaviors to enhance the efficiency of health risk prevention efforts. Method: Guided by multidimensional theories of impulsivity and substance use models of comorbidity, this study used latent profile analysis to examine whether separate, conceptually meaningful profiles of risk for exercise addiction, disordered eating behaviors, and alcohol use would emerge among 503 college students from a large public university. Results: The best-fitting model supported three profiles. MANOVA results revealed significant profile differences based on exercise addiction, binge eating, purging, laxative/pill/diuretic use, exercising longer than 60 minutes, negative urgency, and problematic alcohol use. Profile 3 students (n = 29), labeled the Affect Driven Health Risk-Takers, demonstrated the highest levels of impulsivity (i.e., negative urgency, lack of premeditation, lack of perseverance, and sensation seeking) and the most risk behaviors compared to the other two profiles. Profile membership was associated with distinct levels of negative urgency, exercise addiction, disordered eating behaviors, and problematic alcohol use. A small proportion of undergraduates demonstrated co-occurring exercise addiction, disordered eating behaviors, and problematic alcohol use. Profile membership also predicted the health outcomes of clinically significant exercise addiction and hazardous alcohol use. Conclusions: Findings illuminated how patterns of risk behavior engagement were associated with clinically significant exercise addiction and hazardous alcohol use and will inform prevention efforts and clinical interventions with at-risk college students.

The effect of COVID-19 pandemic and quarantine period on physical activity and dietary habits of college-aged students

The coronavirus disease 2019 (COVID-19) pandemic led to sudden extreme changes in lifestyle, potentially causing adverse changes in physical activity, sedentary behavior, and dietary habits. The objective of the study was to investigate the effects of COVID-19 quarantine on physical activity, dietary habits, and food insecurity among college students who were impacted by the quarantine periods and campus closures. The findings of the study will provide preliminary evidence on dietary, physical activity, and sedentary behavior changes induced by the pandemic among college students.

Participants (n ​= ​403) completed a cross-sectional self-report online questionnaire, evaluating the physical activity, sedentary behavior, and dietary behaviors before- and during-COVID-19 campus closures (March–May 2020). Sociodemographic and descriptive information was also obtained from each participant. Wilcoxon signed-rank test was used to assess changes in physical activity, sedentary behavior, and dietary habits. McNemar's test was used to compare food insecurity changes. Data were presented as median and interquartile range.

A total of 291 participants who met the inclusion criteria were enrolled in the study (college-aged, 18–24 years). Physical activity decreased at vigorous (2 days/week to 1 day/week, p ​< ​0.001), moderate (4 days/week to 1 day/week, p ​< ​0.001), and light (4 days/week to 2 days/week, p ​< ​0.001) intensity levels, while sedentary behavior increased (4 ​h/day to 7 ​h/day, p ​< ​0.001) from pre-to during-COVID-19 quarantine period. Frequencies of meals at home and alcohol consumption increased (Z ​= ​−3.911 and Z ​= ​−4.022, p ​< ​0.001), while frequency of fruit consumption decreased (Z ​= ​−2.116, p ​< ​0.001) from pre-to during-COVID-19 quarantine period. Daily alcohol intake also increased during COVID-19 quarantine period (Z ​= ​−4.442, p ​< ​0.001). Lastly, the percentage of individuals reporting food insecurity significantly increased during COVID-19 quarantine (p ​< ​0.001).

College-aged students in quarantine significantly decreased physical activity participation and increased sedentary behavior. Changes in dietary habits were observed, including increased meals at home, alcohol consumption, and decreased fruit consumption. Food insecurity also doubled among college-aged students during quarantine. Public health strategies to attenuate these changes in lifestyle habits should be implemented during a global pandemic.

Characterising the patterns of and factors associated with increased alcohol consumption since COVID-19 in a UK sample

INTRODUCTION

To examine changes in drinking patterns and to assess factors associated with reported increases in frequency of drinking, units consumed and frequency of heavy episodic drinking (HED) during the UK lockdown.

METHODS

Online cross-sectional survey of 2777 self-selected UK adults.

RESULTS

Thirty percent of participants reported drinking more frequently in lockdown, 16% reported drinking more units per drinking occasion and 14% reported more frequent HED. For men and women, increased frequency of drinking was associated with being less likely to believe alcohol drinking would lead to greater chance of catching COVID-19 (men: OR = 0.99, 95% CI = 0.98, 1.00; women: OR = 0.99, 95% CI = 0.99, 1.00) and deterioration in psychological wellbeing (OR = 1.27, 95% CI = 1.04, 1.54; OR = 1.29, 95% CI = 1.11, 1.51); increased unit consumption was associated with deterioration in financial situation (OR = 1.50, 95% CI = 1.21, 1.86; OR = 1.31, 95% CI = 1.05, 1.64) and physical health (OR = 1.31, 95% CI = 1.03, 1.67; OR = 1.66, 95% CI = 1.31, 2.10). Finally, increases in the frequency of HED were associated with deterioration in psychological wellbeing (OR = 1.65, 95% CI = 1.25, 2.18; OR = 1.46, 95% CI = 1.17, 1.82) and being furloughed (OR = 3.25, 95% CI = 1.80, 5.86; OR = 2.06, 95% CI = 1.19, 3.56). Other gender differences were detected, for example, living with children was associated with an increase in units consumed (OR = 1.72, 95% CI = 1.09, 2.73) and the frequency of HED (OR = 2.40, 95% CI = 1.44, 3.99) for men, but not women.

DISCUSSION AND CONCLUSIONS

In this self-selected UK sample, a significant proportion of individuals reported drinking more frequently in lockdown, drinking more units per drinking occasion and more frequent HED. There were consistent predictors of increased consumption across men and women, but other gender differences were detected. This study identifies groups that may require targeted support in future lockdowns.

Shyness and susceptibility to social influence: Stronger concordance between norms and drinking among shy individuals

Despite a large body of work exploring associations between perceived norms and drinking and norms-based interventions for drinking, less work has examined moderators of associations between norms and drinking outcomes to determine potential sub-groups that might benefit most from brief norms-based interventions. The present study investigates shyness as a moderator of associations between drinking norms and alcohol use. We hypothesized that shyness would moderate associations between drinking norms and alcohol use such that individuals who are higher in shyness might be more sensitive to social influence and thus show stronger associations between drinking norms and alcohol use. Participants included 250 college students (70% female; 44.5% White/Caucasian) aged 18-26 (M = 21.02, SD = 2.16) who met heavy drinking criteria (4/5 drinks on one or more occasions in the past month for women/men). Participants completed measures of demographics, shyness, alcohol use, alcohol-related problems, and drinking norms remotely at baseline and one-month follow-up (N = 169). Drinking norms were negatively associated with shyness and positively associated with baseline and follow-up drinking. Shyness was negatively associated with baseline drinking but not associated with follow-up drinking. Interaction models tested longitudinal associations between shyness, descriptive drinking norms, and follow-up drinking, controlling for baseline drinking and gender. Results showed that associations between drinking norms and drinks per week were strongest among people who were higher in shyness. Individuals who are shy may be more susceptible to social influence and thus may benefit more from a norms-based drinking intervention. Future work may explore shyness as a moderator of norms-based intervention efficacy.

Baseline cortisol predicts drunkorexia in female but not male college students

"Drunkorexia" or compensatory eating behaviors in response to alcohol consumption, resembles a subclinical eating disorder, and is a current public health concern. Eating disorders and alcohol abuse are associated with dysfunction of the hypothalamic-pituitary-adrenal axis (HPA). One index of HPA function is cortisol. As causes of drunkorexia remain elusive, the present study examined cortisol function as it relates to drunkorexia. Participants:n = 73 (49 women) college students. Method: Participants provided daytime saliva samples for cortisol analyses prior to completing an online survey measuring alcohol consumption, drunkorexia, and alcohol problems as measured by the Rutgers Alcohol Problem Index (RAPI). Results: Multiple regressions indicated that baseline cortisol significantly positively correlated with drunkorexia behaviors in women but not men. Higher baseline cortisol and aspects of drunkorexia related to alcohol problems. Conclusion: Programs educating about stress management and health risks of drunkorexia may decrease engagement in drunkorexia behaviors among college students.

Sex and racial/ethnic differences in the prevalence of overweight and obesity among U.S. college students, 2011-2015

To investigate sex and racial/ethnic differences in overweight and obesity in college students. Participants: A nationally representative sample of 319,342 U.S. college students (mean age = 20.4 years; 67.7% female) from Fall 2011 to Spring 2015. Methods: A secondary data analysis of multi-year cross-sectional data was performed. Multiple logistic regression was used to examine factors (e.g. cumulative grade average, year in school, and living place) associated with overweight and obesity determined from BMI calculated by self-reported height and weight. Results: The prevalence of overweight and obesity was significantly higher for both sexes in Spring 2015 than in Fall 2011. Significant differences were found in overweight and obesity by sex and race/ethnicity. Higher adjusted odds ratios for overweight and obesity were observed for men, blacks, and Hispanics (compared to whites). Asians had the lowest adjusted odds of overweight and obesity. Conclusions: Intervention strategies for the prevention and management of overweight and obesity in U.S. college students should consider sex and racial/ethnic inequalities.

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.

Double Vision on Social Media: How Self-Generated Alcohol-Related Content Posts Moderate the Link between Viewing Others' Posts and Drinking

A robust finding is the positive association between self-generated alcohol-related content (SG-ARC) on social media (SM) and drinking among emerging adults; however, the reasons for this relationship are still unclear. A factor that has yet to be explored in combination with SG-ARC is how viewing others' alcohol-related content (ARC) may be impacting young adults' drinking. This cross-sectional study conducted across two universities asked students (N = 780; M = 20.80 years old; SD = 2.29; 67.82% female) to self-report how many SG-ARC posts they posted, to estimate how much they saw others' ARC, and how much they drank weekly. SG-ARC was then evaluated as a moderator of the association between viewing others' ARC and drinking. A negative binomial regression model with robust sandwich estimators was employed. Results revealed that both SG-ARC and viewing others' ARC were positively associated with drinking. A significant two-way interaction between SG-ARC and others' ARC emerged such that viewing others' posts appeared to exert an influence on drinking, particularly for students who did not post as many SG-ARC posts. These findings provide evidence that seeing others' ARC may be socially influencing students to drink, especially if they do not post as much SG-ARC themselves, by altering their internalized drinking norms.

The Role of Alcohol-Related Proactive Dietary Restriction to Feel the Psychoactive Effects of Alcohol Faster on Binge Drinking Frequency among Freshmen College Students

BACKGROUND

There is a positive cross-sectional relationship between alcohol-related proactive dietary restriction to feel the effects of alcohol faster (APDR) and binge drinking, a health and safety issue impacting college students. Objective: To examine: 1) the longitudinal predictive ability of varying levels of APDR on binge drinking frequency; and 1a) the strength of the relationship between varying levels of APDR and binge drinking frequency during freshman year of college (n = 1,149).

METHODS

Ordinal logistic regression was used to model the relationship between APDR and binge drinking frequency.

RESULTS

Main findings suggest APDR of students who reported eating less than usual (low APDR) prior to drinking to feel the effects of alcohol faster was a significant predictor of binge drinking frequency (1.27 (95% CI, 0.06 to 0.42), Wald χ² (1) = 8.46, p=.009) at baseline, but not at 7-month follow-up (1.02 (95% CI, -0.18 to 0.23), Wald χ² (1) = .51, p=.83). APDR for students who reported skipping one or more meals (high APDR) to feel the effects of alcohol faster was not a significant predictor of binge drinking frequency at baseline nor at 7-month follow-up.

CONCLUSION

Low APDR is a significant predictor of binge drinking frequency that is established early in the first semester of college with no significant change occurring in binge drinking frequency over the course of students' freshman year at 7-month follow-up. Campus health professionals are urged to emphasize the detrimental health effects of low APDR early in the first semester of college.

Sex differences in the trajectories of and factors related to extracurricular sport participation and exercise: a cohort study spanning 13 years

BACKGROUND

Extracurricular sport participation and exercise (ESPE) refers to regular exercise/sport participation in addition to the physical education in school among a school-aged population. Rather than general physical activity, ESPE is typically deliberately initiated and presents an efficient target for interventions. However, compared to physical activity, relatively few studies have investigated sex differences in the development of and factors associated with ESPE using a person-centered approach. This study aimed to examine the latent trajectories of ESPE from childhood to emerging adulthood across sexes, and to identify the associated sex-specific individual (i.e., body mass index, body dissatisfaction, stress, and screen behavior) and parental (i.e., parental exercise and parental screen behavior) factors.

METHODS

This study used data from part of the Child and Adolescent Behavior in Long-term Evolution (CABLE) project, which comprised 2072 fourth graders (aged 9 years) in Northern Taiwan followed annually from 2001 to 2013 (13 waves). Repeated-measures latent class analysis was used to identify the trajectories of ESPE for males and females, respectively. Multinomial logistic regression was further used to identify sex-specific factors related to ESPE.

RESULTS

Four trajectories of ESPE were identified for males and females. For males, these trajectories were Rarely-to-Never (20%), Often-to-Rarely (32%), Always-to-Never (21%), and Always (27%). For females, these trajectories were Rarely-to-Never (34%), Rarely (23%), Always-to-Rarely (33%), and Always (10%). We observed that the developmental patterns of ESPE varied by sex such that there was an earlier decline in the trajectories of ESPE in females than in males and that, compared with males, fewer females maintained exercise habits in young adulthood. Furthermore, we found several sex-specific factors related to ESPE, namely, stress, BMI, and parental exercise. Body dissatisfaction and individual screen behavior were associated with trajectories of ESPE for both sexes.

CONCLUSIONS

We found distinct trajectories of ESPE from childhood to emerging adulthood for both sexes. The trajectories of ESPE for males and females, however, differ in terms of patterns and associated factors. Our findings suggest that efforts to increase ESPE should be initiated early, and may be made more effective by considering sex differences.

Examining the effect of weight conscious drinking on binge drinking frequency among college freshmen

To examine the effect of weight-conscious drinking and compensatory behavior temporality on binge drinking frequency of college freshmen. Participants: Freshmen (n = 1149) from eight US universities, Fall 2015. Methods: Participants completed the Compensatory Eating Behaviors in Response to Alcohol Consumption Scale and Alcohol Use Disorders Identification Test-Consumption. Structural equation modeling was used to model the effect of weight-conscious drinking constructs on binge drinking frequency. Results: Bulimia, Dietary Restraint and Exercise, Restriction, proactive Alcohol Effects, during Alcohol Effects, and proactive Dietary Restraint and Exercise factors significantly predicted binge drinking frequency. Conclusion: Weight-conscious drinking among this cohort of college students comprises temporal factors significantly associated with binge drinking frequency. Relationships between Bulimia, Dietary Restraint and Exercise, and Restriction compensatory behaviors and binge drinking should be considered in interventions to address binge drinking among college students.

Sex and racial/ethnic differences in sleep quality and its relationship with body weight status among US college students

Objective: To examine sex and racial/ethnic differences in sleep quality and the association between sleep quality and body weight status among US college students. Participants: A nationally representative sample (N = 324,767) of college students from 2011 to 2015. Methods: A secondary data analysis of cross-sectional data. Results: Women showed poorer sleep quality (nights per week getting enough sleep to feel rested) than men (4.00 versus 4.34 days; p < .001). In both men and women, compared with non-Hispanic whites, racial/ethnic minorities showed lower sleep quality (p < .001). Compared with normal weight participants, overweight participants had poorer sleep quality (p = .007) among men, and both overweight (p = .004) and obese participants (p < .001) had lower sleep quality among women. Conclusions: Understanding sex and racial/ethnic sleep differences and the association between sleep and body weight status is important for colleges to promote college students' healthy sleep.

Assessment of Alcohol Consumption and Anxiety as Predictors of Risk of Anorexia and Bulimia in Non-Clinicals Samples

The objective of this study is to assess the effect of alcohol consumption, anxiety, and food restriction before and after consuming alcohol and body image on the risk of anorexia and bulimia in college students from Tijuana, Baja California, through predictive statistical models. A quantitative, descriptive, and cross-sectional design and a non-probabilistic sample of 526 college students from Tijuana, Baja California, México were used. Application of the scales (with acceptable psychometric properties) was conducted in classrooms. Through path analyses, four models were found with adequate indicators of goodness of fit: (1) risk of anorexia in women [Chi Square (X²) = 5.34, p = 0.376, Adjusted Determination Coefficient (R²)= 0.250]; (2) anorexia risk for men (X² = 13.067, p = 0.192, R² = 0.058); (3) risk of bulimia in women (X² = 3.358, p = 0.645, R² = 0.202); and bulimia risk for men (X² = 14.256, p = 0.075, R² = 0.284). The findings provide empirical evidence for the food and alcohol disturbance model.

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.

LEVEL OF EVIDENCE

Level V, descriptive study.

Drunkorexia: A new term and diagnostic criteria

Individuals who restrict their caloric intake and/or exercise excessively to mitigate the calories from alcohol consumption may suffer from an eating disorder, substance abuse disorder, or both. While the term "drunkorexia" has been used in both academic articles and popular culture, issues persist with respect to diagnosing and treating this condition. Classifying the behavior as a subcategory of Other Specified Feeding and Eating Disorders (OSFED) would provide patients with an increased likelihood of receiving insurance coverage for this condition. A consistent definition of this behavior and a more medically accurate/appropriate term-such as "alcoholimia"-are both needed to advance treatment and prevention efforts.

Drunkorexia: Disordered eating behaviors and risky alcohol consumption among adolescents

The first goal of our study was to examine the differences on disordered eating and alcohol consumption among heavy, occasional restrictors, and non-restrictors in a sample of 823 adolescents. The second goal was to analyze the relation of drunkorexia between unhealthy eating and alcohol use. Our results showed that heavy restrictors reported more eating disorder symptoms and alcohol use than occasional restrictors and non-restrictors. Similarly, occasional restrictors showed more unhealthy eating and drinking behaviors than non-restrictors. Both disordered eating and alcohol use were significant predictors of drunkorexia, supporting the argument of drunkorexia as an overlapping of dysfunctional eating and drinking patterns.

Examination of the relationships between dietary restraint, alcohol, and adverse problems among women

OBJECTIVE

Women who report greater chronic dieting consume more alcohol, drink more frequently, and experience greater problems than women who report less chronic dieting. Alcohol may also temporarily disrupt a woman's dietary rules, leading to increased caloric intake and subsequent restriction. This study examined whether alcohol use mediated the relationship between dietary restraint and alcohol problems in a woman's daily life.

PARTICIPANTS

Women (N = 59) completed the study by the fall of 2013.

METHODS

Participants completed up to six assessments for 10 days, including intended dietary restraint, alcohol use, and problems.

RESULTS

Drinking quantity partially mediated the relationship between dietary restraint and alcohol problems. For each drink consumed, there was a 1.4 times greater likelihood of eating after drinking, which was associated with greater intention to subsequently restrict calories.

CONCLUSIONS

The types of drinks consumed and reasons for restricting one's caloric intake may inform the relationship between these behaviors.

Racial/ethnic differences in body weight perception among U.S. college students

OBJECTIVE

To examine racial/ethnic differences in weight perception by sex among U.S. college students.

PARTICIPANTS

a national sample (N = 70,267) of college students selected from 2- and 4-year postsecondary institutions (N = 62) during the Fall semester from 2011 to 2014.

METHODS

This is a secondary data analysis using 4 years of American College Health Association-National College Health Assessment IIb data. Sex-stratified multinomial logistic regression was performed to investigate racial/ethnic differences in body weight perception.

RESULTS

Compared with non-Hispanic whites, non-Hispanic black men and women were more likely to underestimate their body weight (p < .01). Asian men and women were more likely to overestimate their body weight than non-Hispanic whites (p < .001).

CONCLUSIONS

Weight-related interventions should take into account racial/ethnic differences in body weight perception.

Behavioral Correlates of Empirically-Derived Dietary Patterns among University Students

Given the importance of young adulthood in establishing lifelong dietary habits, it is imperative to better understand potential underlying drivers of dietary behavior in the university-age population. Dietary patterns have been associated with disease risk, but behavioral predictors of dietary pattern adherence are poorly understood, especially among emerging adults. This study aims to evaluate health-related behaviors associated with dietary pattern scores among freshmen participating in the Tufts Longitudinal Health Study (TLHS; n = 630). We previously derived dietary patterns using principal components analysis and orthogonal rotation from dietary intake data. Health-related behavior data were collected via survey. All data were collected during the Spring semesters of 1998⁻2007. Unadjusted linear models were used to determine associations between dietary pattern scores and health-related behaviors. Significant correlates were retained in multivariable regression models, which were adjusted for demographic characteristics. We found that never eating meals away from home was associated with higher adherence to the Prudent and lower adherence to the Western and Alcohol patterns. Intention to lose weight was negatively associated with the Western pattern, while intention to gain weight was positively associated with all dietary patterns. These findings suggest that intervention efforts aimed at improving eating out behaviors and engaging in healthy weight management strategies may promote healthier dietary patterns among university students.

Alcohol use and strenuous physical activity in college students: A longitudinal test of 2 explanatory models of health behavior

OBJECTIVE

To help clarify the effect of gender on the bidirectional relationship between alcohol use and strenuous physical activity in college students.

PARTICIPANTS

Five hundred twenty-four (52% female) college students recruited in August 2008 and 2009 and followed up in April 2009 and April 2011, respectively.

METHODS

Participants reported their alcohol use and strenuous physical activity on 2 occasions (baseline and follow-up) spaced approximately 1 or 2 years apart.

RESULTS

For females, alcohol use quantity at baseline was associated with increased strenuous physical activity at 1- and 2-year follow-ups, and alcohol use frequency at baseline was associated with decreased strenuous physical activity at 2-year follow-up. For males, alcohol use frequency at baseline predicted decreased strenuous physical activity at 1-year follow-up.

CONCLUSIONS

Gender differences may be explained from an eating disorders perspective such that women use physical activity as a compensatory strategy to combat potential weight gain from calories consumed during alcohol use.

Gender-moderated links between urgency, binge drinking, and excessive exercise

OBJECTIVE

Exercise correlates with alcohol use, but the nature of this relation and the extent to which it is maladaptive remains unclear. Urgency and motives for engaging in drinking and exercise might indicate when these behaviors are problematic. The current study examined whether urgency moderated the association between exercise motivated by weight loss and drinking.

PARTICIPANTS

College students (N = 589, 45.7% male) completed the study during the spring of 2012.

METHODS

Participants completed self-report assessment measures, including frequency/quantity of alcohol consumption, exercise for weight loss, and urgency, during a single session.

RESULTS

Negative urgency moderated the relation between exercise and alcohol consumption in men but not women; the link between excessive exercise and alcohol use was stronger for men with higher levels of urgency.

CONCLUSIONS

Further clarification of the mechanisms underlying alcohol use and physical activity-particularly maladaptive approaches to exercise-will inform health interventions among college students.

Cross-Sectional Associations between Empirically-Derived Dietary Patterns and Indicators of Disease Risk among University Students

The transition from adolescence to adulthood is a unique period during which lifelong dietary habits are shaped. Dietary patterns (DPs) among young adults attending college have not been adequately described, and associations between DPs and indicators of disease risk are not well understood in this age group. Dietary data were collected from undergraduates participating in the Tufts Longitudinal Health Study (TLHS; 1998-2007) by Food Frequency Questionnaire (FFQ; n = 1323). DPs were derived using principal components analysis with varimax rotation. Scree plots; eigenvalues; factor loadings; and previous studies were used to determine and label the DPs retained. Cross-sectional relationships between DP scores and anthropometric measures (percent body fat (PBF) and (BMI) and lipid biomarkers (total; HDL and LDL cholesterol; and triglycerides) were assessed with multivariable regression models; adjusted for demographics; physical activity; smoking; intention to gain/lose weight; and total energy intake. Effect modification by sex was tested. Three DPs were identified: Prudent; Western; and Alcohol. Greater adherence to the Prudent DP was associated with favorable anthropometric outcomes. The Alcohol DP was associated with a favorable lipid profile. Associations between the Western DP and blood lipids differed by sex; with unfavorable impact observed only among males. Our findings add to the literature linking DPs in young adults with measurable adiposity and cardiometabolic outcomes; suggesting that improving nutrition among college students could reduce chronic disease risk.

Validation of the Italian version of the Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS)

The aim of the study was to evaluate, in a representative sample of high school students, the psychometric characteristics of the Italian version of the CEBRACS scale (Rahal et al., 2011), a questionnaire investigating compensatory eating behaviors correlated with alcohol consumption. These behaviors are adopted to make up for calories consumed through the drinking of alcohol and/or to enhance the intoxicative effects of alcohol. Study participants were selected from an initial sample of 965 students. Out of the 965 youths originally recruited, 640 (376 males and 264 females) reported drinking alcohol over the previous 3 months, and were considered eligible for the purpose of the study. The following questionnaires were administered: CEBRACS, Alcohol Use Disorders Identification Test (AUDIT) (Saunders, 1993), and the Eating Disorder Inventory-3 (EDI-3) (Garner, 2004). Test/retest reproducibility was evaluated on a subgroup of 189 youths. The factorial structure, internal consistency, test–retest reliability and concurrent validity of CEBRACS were evaluated. Factor analysis of inter-item correlation indicated 5 factors as being better suited to describe data, with an estimated 68.85% variance: "Alcohol Effect, "Laxative Use", "Dietary Restraint and Exercise", "Diuretic Use", "Restriction and Vomiting". A high degree of reproducibility and homogeneity (ICC = 0.806; Cronbach's Alpha = 0.886) of the scale was detected. A significant correlation was revealed between CEBRACS, the three eating disorder risk scales comprised in EDI-3 and scores and clinical risk yielded by AUDIT. The overall reliability and validity of the CEBRACS scale was confirmed in an extensive sample of Italian students, highlighting a satisfactory construct validity, good internal consistency and good degree of reproducibility. In view of the relevance of the problem, associated with serious health risks, a more widespread investigation of the phenomenon should be conducted using evaluation tools of proven validity and reliability on both representative samples of the general population and clinical samples.

Exploring the motives and mental health correlates of intentional food restriction prior to alcohol use in university students

This study explored the prevalence of and motivations behind ‘drunkorexia’ – restricting food intake prior to drinking alcohol. For both male and female university students ( N = 3409), intentionally changing eating behaviour prior to drinking alcohol was common practice (46%). Analyses performed on a targeted sample of women ( n = 226) revealed that food restriction prior to alcohol use was associated with greater symptomology than eating more food. Those who restrict eating prior to drinking to avoid weight gain scored higher on measures of disordered eating, whereas those who restrict to get intoxicated faster scored higher on measures of alcohol abuse.

Patterns of compensatory behaviors and disordered eating in college students

Abstract.

OBJECTIVE

The current study investigated rates of endorsement of eating-related compensatory behaviors within a college sample.

PARTICIPANTS

This sample included male and female students (N = 1,158).

METHODS

PARTICIPANTS completed the Eating Disorder Examination Questionnaire (EDE-Q). The study defined 3 groups of students: those who did not endorse purging behaviors, those who endorsed only exercise, and those who endorsed laxative use or vomiting. Rates of related eating disorder risk variables were compared across the 3 groups.

RESULTS

Almost half of college students reported utilizing exercise as a compensatory strategy over the past 28 days. Those reporting compensatory exercise did not differ from other community and college samples on EDE-Q subscales.

CONCLUSIONS

Findings suggest that college students report significant rates of compensatory exercise, and those who report exercise as their only compensatory behavior also report relatively low levels of eating disorder risk.

"Drunkorexia": exploring the who and why of a disturbing trend in college students' eating and drinking behaviors

OBJECTIVE

"Drunkorexia," limiting food intake before alcohol consumption, increases college students' risk for negative alcohol-related health consequences. The current study tested whether (1) women engage in drunkorexia more frequently than men; (2) weight control motivations explain sex differences in drunkorexia; and (3) among women, weight control motivations are a particularly strong predictor of drunkorexia for heavier drinkers.

PARTICIPANTS

Undergraduate males and females (N = 63) recruited during fall of 2011.

METHODS

PARTICIPANTS self-reported their alcohol consumption, drunkorexia, and weight control motivations online.

RESULTS

Findings supported hypotheses: weight control motivations explained why women engage in drunkorexia more than men; and the weight control motivation → drunkorexia relation was strongest for heavier- (vs lighter-) drinking women.

CONCLUSION

Women have more weight concerns than men, which makes them more likely to engage in drunkorexia. Heavy-drinking women with strong weight control motivations are at greatest risk for drunkorexia. Interventions should help students more safely reconcile pressures to be thin and drink alcohol.
