A Qualitative Investigation of the Relationship Between Consumption, Physical Activity, Eating Disorders, and Weight Consciousness

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.

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.

Energy labelling of alcoholic drinks: An important or inconsequential obesity policy?

Alcohol is calorie dense, but unlike food products, alcoholic drinks tend to be exempt from nutritional labelling laws that require energy content information to be displayed on packaging or at point of purchase. This review provides a perspective on the likely efficacy of alcoholic drink energy labelling as a public health policy to reduce obesity and discusses key questions to be addressed by future research. First, the contribution that alcohol makes to population level daily energy intake and obesity is outlined. Next, consumer need for alcohol energy labelling and the potential impacts on both consumer and industry behavior are discussed. Pathways and mechanisms by which energy labelling of alcoholic drinks could reduce obesity are considered, as well as possible unintended consequences of alcoholic drink energy labelling. Would widespread energy labelling of alcoholic drinks reduce obesity? The unclear effect that alcohol has on population level obesity, the modest contribution calories from alcohol make to daily energy intake and limited impact nutritional labelling policies tend to have on behavior, suggest alcohol energy labelling may have limited impact on population obesity prevalence as a standalone policy. However, there are a number of questions that will need to be answered by future research to make definitive conclusions on the potential for alcohol energy labelling policies to reduce obesity.

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.

Impact of High Fat Diet and Ethanol Consumption on Neurocircuitry Regulating Emotional Processing and Metabolic Function

The prevalence of psychiatry disorders such as anxiety and depression has steadily increased in recent years in the United States. This increased risk for anxiety and depression is associated with excess weight gain, which is often due to over-consumption of western diets that are typically high in fat, as well as with binge eating disorders, which often overlap with overweight and obesity outcomes. This finding suggests that diet, particularly diets high in fat, may have important consequences on the neurocircuitry regulating emotional processing as well as metabolic functions. Depression and anxiety disorders are also often comorbid with alcohol and substance use disorders. It is well-characterized that many of the neurocircuits that become dysregulated by overconsumption of high fat foods are also involved in drug and alcohol use disorders, suggesting overlapping central dysfunction may be involved. Emerging preclinical data suggest that high fat diets may be an important contributor to increased susceptibility of binge drug and ethanol intake in animal models, suggesting diet could be an important aspect in the etiology of substance use disorders. Neuroinflammation in pivotal brain regions modulating metabolic function, food intake, and binge-like behaviors, such as the hypothalamus, mesolimbic dopamine circuits, and amygdala, may be a critical link between diet, ethanol, metabolic dysfunction, and neuropsychiatric conditions. This brief review will provide an overview of behavioral and physiological changes elicited by both diets high in fat and ethanol consumption, as well as some of their potential effects on neurocircuitry regulating emotional processing and metabolic function.

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.

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.

Access schedules mediate the impact of high fat diet on ethanol intake and insulin and glucose function in mice

Alcoholism and high fat diet (HFD)-induced obesity individually promote insulin resistance and glucose intolerance in clinical populations, increasing risk for metabolic diseases. HFD can also stimulate alcohol intake in short-term clinical studies. Unfortunately, there is currently a disconnect between animal models and the clinical findings, as animal studies typically show that HFD decreases ethanol intake while ethanol intake mitigates HFD-induced effects on insulin and glucose dysfunction. However, most previous animal studies utilized forced or continuous HFD and/or ethanol. In three experiments we sought to determine whether HFD (HFD = 60% calories from fat) vs. control diet (chow = 16% fat) alters voluntary two-bottle choice ethanol intake in male C57Bl/6J mice given differing access schedules for 6-7 weeks, and we assessed the resultant impact on metabolic function via insulin and glucose tolerance tests. Experiment 1: Unlimited Access Ethanol + HFD (UAE + HFD; n = 15; 10% ethanol v/v, ad libitum diet and ethanol) or UAE + Chow (n = 15). Experiment 2: Limited Access Ethanol + HFD (LAE + HFD; n = 15; ethanol = 4 h/day; 3 days/week, ad libitum diet) or LAE + Chow (n = 15) with increasing ethanol concentrations (10%, 15%, 20%). Experiment 3: Intermittent HFD with limited access to ethanol (iHFD-E; HFD = single 24-h session/week; ethanol = 4 h/day; 4 days/week) (n = 10). UAE + HFD mice consumed significantly less ethanol and were insulin-resistant and hyperglycemic compared with UAE + Chow mice. LAE + HFD mice consumed ethanol similarly to LAE + Chow mice, but exhibited hyperglycemia, insulin resistance, and glucose intolerance. iHFD-E mice displayed binge eating-like behaviors and consumed significantly more ethanol than mice given ad libitum chow or HFD. iHFD-E mice did not have significantly altered body composition, but developed insulin insensitivity and glucose intolerance. These findings suggest that access schedules influence HFD effects on ethanol consumption and resultant metabolic dysfunction, ethanol intake does not improve HFD-induced metabolic dysfunction, and binge eating-like behaviors can transfer to binge drinking behaviors.

Diet quality, nutrient intakes and biochemical status of New Zealand women of childbearing age according to alcohol consumption patterns

OBJECTIVE

To investigate associations between alcohol consumption patterns and diet quality, nutrient intakes and biochemical profile of women of childbearing age.

DESIGN

Nutrient intake data from 24 h diet recalls, alcohol consumption data and diet quality from the Dietary Habits Questionnaire, and biochemical analyses from the cross-sectional 2008/09 Adult Nutrition Survey in New Zealand.

SETTING

New Zealand households.

PARTICIPANTS

New Zealand women aged 18-45 years (n 1124).

RESULTS

All analyses were completed using Stata and survey weights were used to allow for the complex survey design to produce population estimates. Multinomial logistic regression models were used to examine the associations between drinking patterns and the variables of interest, with 'infrequent moderate/light' drinkers being the reference category. The findings indicate that alcohol-consuming women of childbearing age tend to replace food energy with alcohol energy (P = 0·022). 'More frequent heavy' and 'more frequent moderate/light' drinkers had higher intakes of total, mono- and polyunsaturated fats with the latter group also consuming higher levels of saturated fats (P < 0·05). Women who were 'infrequent moderate/light' drinkers had relatively better diet quality, nutrient intakes and adequate biochemical status in comparison to other drinkers and abstainers. 'Infrequent heavy' drinkers, who were predominantly younger in age, had lower serum vitamin B12 levels (P = 0·01) with a higher proportion of women in this category having below-recommended levels of serum folate (P < 0·05).

CONCLUSIONS

Alcohol consumption, especially heavy drinking patterns, may compromise nutritional status of women of childbearing age.

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.

Correlates of long-term physical activity adherence in women

BACKGROUND

Little is known about the factors that may influence women's adherence to moderate-to-vigorous physical activity (MVPA) using longitudinal data. The purpose of this study was to examine the correlates of long-term physical activity (PA) participation among women.

METHODS

Female data from Waves I, III, and IV (n = 5381) of the National Longitudinal Study of Adolescent to Adult Health (Add Health) were used for the analysis. The outcome of PA adherence was operationalized as (1) consistently physically active (at least 5 instances during the week) in both Waves III and IV (during adulthood), and (2) consistently not physically active or only physically active in either Wave III or IV. Predictor variables from Wave I (during adolescence) included race/ethnicity, PA level, self-perception of being physically fit, general health status, attempt to change weight, parents' income level, parents' education, well-being, depression, access to PA resources, days of physical education (PE), and grade level. Crude and adjusted logistic regression models were utilized to estimate the adjusted odds ratio (aOR) and 95% confidence interval (95%CI) for the outcome variable.

RESULTS

PA levels during adolescence significantly predicted PA adherence (aOR = 1.67, 95%CI: 1.35-2.05). Additionally, wanting to lose weight (aOR = 1.49, 95%CI: 1.20-1.85), using fitness center in the neighborhood (aOR = 1.29, 95%CI: 1.05-1.58), and having 5 days of PE a week (aOR = 1.48, 95%CI: 1.09-2.02) were significant predictors. Women who did not perceive being physically fit (aOR = 0.65, 95%CI: 0.44-0.95) and Black, non-Hispanics (aOR = 0.60, 95%CI: 0.44-0.82) were less likely to adhere to PA.

CONCLUSION

The findings suggested that physically active adolescents were more likely to become active adults. Future research should address interventions (e.g., PE program, community resources) that may promote lifetime PA in women, with the goal of decreasing morbidity and mortality.

Are clear boundaries a prerequisite for well-functioning collaboration in home health care? A mixed methods study

AIM

The aim of this study was to examine whether professional collaboration in home health care is associated with clear boundaries between principals' areas of responsibility and the professions areas of responsibility, respectively.

METHODS

Data were derived from a web-based survey that was carried out in one county in the middle of Sweden during spring 2013. Participants were health professionals and managers from the county council and from all the municipalities in the county. Both structured and open-ended questions were utilised. A total of 421 individuals (90% women) answered the structured questions, and 91 individuals (22% of the 421) answered the open-ended questions. Quantitative data were analysed with descriptive statistics methods, tests of independence and of correlation strength. Qualitative data were analysed with content analysis.

RESULTS

The results from the structured questions showed that well-functioning collaboration was associated with clear boundaries between principals in the county overall, and for respondents in two of three parts of the county. Association between clear boundaries between professions and well-functioning collaboration was found in the county overall among the municipality population. However, in one part of the county, we did not find any correlations between well-functioning collaboration and clear boundaries between professions or principals, with the exception of home help services. The analysis of the open questions gave similar results as the quantitative analysis, illustrated within three themes: The significance of concepts, trust and interdependence, and collaboration as a means for well-being.

CONCLUSION

The results indicate that, recently after an organisational change, clear boundaries between the principals' areas of responsibility and professions' area of responsibility respectively are necessary for effective cooperation between professionals. If the organisation and professionals have previous positive experience of colocated activities, clear boundaries do not share the same importance.

Gender orientation and alcohol-related weight control behavior among male and female college students

OBJECTIVE

We examine weight control behavior used to (a) compensate for caloric content of heavy alcohol use; and (b) enhance the psychoactive effects of alcohol among college students. We evaluate the role of gender orientation and sex.

PARTICIPANTS

Participants completed an online survey (N = 651; 59.9% women; 40.1% men).

METHOD

Weight control behavior was assessed via the Compensatory-Eating-and-Behaviors-in Response-to-Alcohol-Consumption-Scale. Control variables included sex, race/ethnicity, age, and depressive symptoms. Gender orientation was measured by the Bem Sex Role Inventory. The prevalence and probability of alcohol-related weight control behavior using ordinal logistic regression are reported.

RESULTS

Men and women do not significantly differ in compensatory-weight-control-behavior. However, regression models suggest that recent binge drinking, other substance use, and masculine orientation are positively associated with alcohol-related weight control behavior.

CONCLUSIONS

Sex was not a robust predictor of weight control behavior. Masculine orientation should be considered a possible risk factor for these behaviors and considered when designing prevention and intervention strategies.

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.
