Exploring the links between unhealthy eating behaviour and heavy alcohol use in the social, emotional and cultural lives of young adults (aged 18-25): A qualitative research study

Nutritional habits and eating attitude in university students during the last wave of COVID-19 in Spain

Emotional Eating is eating in response to negative emotional states, such as boredom, loneliness, or anxiety. For some young people, both food and alcohol are a source of pleasure in their social life. A cross-sectional study was conducted in 2022-23 in the Health Sciences Faculty. Mediterranean Diet Adherence Test, alcohol use disorders identification test (AUDIT), Emotional Eater Questionnaire (EEQ), Pittsburgh Sleep Quality Index, Yale Food Addiction, Perceived Stress Scale, and Anxiety Questionnaire STAI, were employed. Emotional eater (EE) regarding to no emotional eater (NEE) presented a mild food addiction, a significantly high intake of carbohydrates, fat, and alcohol. Energy intake is dependent on saturated fat, also they are not conscious of their intake of calories, had worse sleep quality, high perceived stress, and worse healthy eating index (HEI) due to their intake of sweets and soft drinks. The diet quality could be affected by the stress of the pandemic. The association of emotional eating with the intake of sweet foods and alcoholic drinks maybe is a remaining situation of COVID-19. We suppose that maladaptive eating behaviors have improved over time during this pandemic. Even though it is necessary to promote healthier eating among university students, it is also necessary to improve healthy habits.

Diet modifies the association between alcohol consumption and severe alcohol-related liver disease incidence

It is elusive why some heavy drinkers progress to severe alcohol-related liver disease (ALD) while others do not. This study aimed to investigate if the association between alcohol consumption and severe ALD is modified by diet. This prospective study included 303,269 UK Biobank participants. Alcohol consumption and diet were self-reported. The diet score was created from 4 items selected using LASSO. Cox proportional hazard model showed that the diet score was monotonically associated with severe ALD risk, adjusted for sociodemographics, lifestyle factors, and alcohol consumption. Relative excess risk due to interaction analysis indicated that having a higher ALD diet score and a higher alcohol consumption simultaneously confers to 2.44 times (95% CI: 1.06-3.83) higher risk than the sum of excess risk of each factor. In this work, we show that people who have a poor diet might be more susceptible to severe ALD due to alcohol consumption.

Tobacco and alcohol co-use: Lifestyle and sociodemographic factors, and personality aspects as potential predictors in the "Seguimiento Universidad de Navarra" cohort

Tobacco and alcohol co-use are two major lifestyle modifiable risk factors. Understanding the determinants of both behaviors helps to develop interventions to prevent these exposures. However, previous studies have focused on predictors of individual tobacco or alcohol use. This study aims to explore the potential predictors of tobacco and alcohol co-use among Spanish university graduates from the "Seguimiento Universidad de Navarra" (SUN) cohort study. A total of 7175 participants who were co-users of tobacco and alcohol were selected for this cross-sectional analysis. Their mean age was 39.1 years (12.04 SD) and 57.3% were women. Univariate regression models were used to select the potential predictors of tobacco and alcohol co-use, and the areas under the ROC curves (AUC) were calculated. Multivariable logistic regression models were used to create a predictive model. Baseline potential predictors included sociodemographic factors, lifestyle habits, and perceived personality aspects. In the multivariable model, the main significant potential predictors of tobacco and alcohol co-use were driving under the influence of alcohol (odds ratio [OR] = 1.65 [1.43-1.90]), drinking 1-2 cups of coffee daily (OR = 1.50 [1.24-1.84]), drinking three or more cups of coffee daily (OR = 1.61 [1.35-1.91]), and doing more physical activity than recommended (OR = 1.18 [1.02-1.34]) when compared with the reference group. Conversely, those who were married (OR = 0.87 [0.75-0.99], ate at home 7 days a week (OR = 0.69 [0.60-0.80]), or had a high perceived level of competitiveness (OR = 0.83 [0.72-0.95]) had a lower risk of co-use (AUC 0.61 [confidence interval 95% 0.59-0.63]), compared to the reference group. These results could be used by healthcare professionals, especially nurses, to effectively assess patients at higher risk of tobacco and alcohol co-use.

Nutrient intake, alcohol consumption, emotional eating and anxiety in women nursing students

Objective

The aim of the study was to analyze dietary habits, alcohol habits, emotional eating and anxiety in a sample of Spanish nursing students. These students appear to be essential to the field of public health and to teaching their future patients about their own good practices.

Methods

A cross-sectional investigation was conducted. Participants completed the Emotional Eater Questionnaire, the Alcohol Use Disorder Identification Test (AUDIT) test to evaluate alcohol intake, the State-Trait anxiety Inventory (STAI) test to measure levels of anxiety as a state and anxiety as a trait, and self-reported sociodemographic data. Following classroom instruction, three-day food records were used to gauge food intake.

Results

The calorie intake for the macronutrients Ca, Mg, K, and Fe were below the Recommended Dietary Intakes (DRI) and imbalanced. The percentage E of proteins was 132.7 % more than recommended, while the percentage of carbohydrates is below the recommended level. Dietary energy consumption barely equaled 78 % of the total energy consumed by this sex and age group. With respect to emotional eating, nursing women students were low emotional eater (44 %) > emotional eater (30 %) > non-emotional eater (22.7 %). The students' emotional eating is substantially connected with fast food and sweets, or less healthy food intake behaviors. According to the Alcohol Use Disorder Identification Test (AUDIT), 82.7 % of female students used alcohol on a regular basis in a low-risk manner.

Conclusion

The findings demonstrated a link between anxiety and dietary fat intake. Trait anxiety was negatively connected with emotional eating (EE), whereas state anxiety was positively correlated with meat consumption. It is crucial to consider these findings when creating prevention/intervention plans and profiles of harmful eating behaviors.

Alcohol and morality: one alcoholic drink is enough to make people declare to harm others and behave impurely

We aimed to understand if alcohol intoxication affects the willingness to violate moral foundations (care, fairness, authority, loyalty, and purity). We conducted a laboratory study (N = 387) with three randomized groups: alcohol intoxication, placebo, and control, measuring the sacralization of moral foundations via the Moral Foundations Sacredness Scale. The study showed intoxicated participants sacralized moral foundations of care and purity more often than participants from control and placebo groups. It means participants declared more willing to physically harm other people and animals and behave impurely, e.g., doing deviant sexual behaviors or selling their souls. No differences related to fairness, authority, and loyalty were found. Our study helps to understand the decision processes underlying immoral behaviors, including crimes. We showed that even one drink makes people change their judgments about what is right and wrong (in the cases of harmful and impure behaviors), and because this kind of judgment precedes immoral behaviors, our results may help explain why some people under the influence of alcohol break the rules by doing things which they would never do when sober.

The Singaporean foodscape - Convenience, choice, entertainment, and sociality for young workers

Singapore is famous for its diverse, affordable, and exciting foodscape. This paper focuses on understanding the multifaceted role that the Singaporean food environment plays in working young adults' lives, and how young adults interact with this environment to make food choices. Using a focused ethnographic approach, including 33 semi-structured interviews and participant-observation, we explore the ways in which busy working young adults interact with the foodscape. The food environment provides young adults, who eat out frequently, with highly accessible food options that cater to their budgets and palates. They often dine at hawker centres and similar food establishments with colleagues, friends and family. These establishments offer accessible, affordable, and appealing food. Overall, the foodscape provides a source of popular entertainment through the exploration of diverse cuisines and novel shared social experiences. Young adults are heavy users of social media to maintain social networks and to explore the food environment. Capitalizing on this, food marketing on social media targets this group with the promotion of food-related experiences. While it may not always promote healthy eating, the Singaporean foodscape offers convenience, choice, entertainment, and sociality. In the process, it facilitates the formation of cultural and national identity and the protection of mental well-being through the maintenance and development of relationships, and a sense of belonging.

Macronutrient Intake, Sleep Quality, Anxiety, Adherence to a Mediterranean Diet and Emotional Eating among Female Health Science Undergraduate Students

INTRODUCTION

COVID-19 provoked a myriad of challenges for people's health, poor life satisfaction and an unhealthy diet that could be associated with serious negative health outcomes and behaviours. University is a stressful environment that is associated with unhealthy changes in the eating behaviours of students. The association between diet and mental health is complex and bidirectional, depending on the motivation to eat; emotional eaters regulate their emotions through the increased consumption of comfort foods.

OBJECTIVE

The aim of this study was to compare the nutritional habits, alcohol consumption, anxiety and sleep quality of female health science college students.

MATERIAL AND METHODS

A cross-sectional study of 191 female undergraduate students in Madrid was used. Their body mass index and waist hip ratio were measured. The questionnaires used included the Mediterranean Diet Adherence test, AUDIT, Emotional Eater Questionnaire, Pittsburgh Sleep Quality Index, and Food Addiction, Perceived Stress Scale and STAI questionnaires.

RESULTS

We observed a high intake of protein, fat, saturated fatty acids and cholesterol. Overall, 9.5% never had breakfast, and 66.5% consciously reduced their food intake. According to Pittsburgh Sleep Quality Index, they mainly slept 6-7 h, and 82% presented with a poor sleep quality; 13.5% presented moderate-high food addiction, and 35% had moderate Mediterranean Diet Adherence score.

CONCLUSION

Female students' macronutrient imbalances were noted, with a high-level protein and fat intake diet and a low proportion of carbohydrates and fibre. A high proportion of them need alcohol education and, depending on the social context, they mainly drank beer and spirits.

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.

Association Between Emotional Eating, Sociodemographic Characteristics, Physical Activity, Sleep Duration, and Mental and Physical Health in Young Adults

BACKGROUND

Emotional eating (EmE) is one of the most common eating behaviors maladaptive among young adults, however, in the Peruvian context, it remains unexplored.

OBJECTIVE

The aim of the study was to determine the association between negative EmE, sociodemographic characteristics, physical activity, sleep duration, and mental and physical health in young adults.

METHODS

A cross-sectional study was conducted in 400 young Peruvian adults living in three regions of Peru (coast, jungle, and highlands). An online survey was used to collect information on sociodemographic characteristics, physical activity, sleep duration, depressive symptoms, anxiety, hypertension, and negative EmE. In addition, self-reported anthropometric data were collected to calculate body mass index (BMI).

RESULTS

Approximately 55.8% of women presented negative EmE. Logistic regression analysis revealed that participants aged 30-39 years were less likely to have negative EmE in both female and male gender, OR; 0.24, 95% CI; 0.08-0.66, p<0.01 and OR; 0.40, 95% CI; 0.16-0.97, p<0.05, respectively. Perform physical activity 3 to 4 times 5.22 (95% CI: 1.31-20.78), 1 to 2 times a week 5.77 (95% CI: 1.91-17.44), and never 15.18 (95% CI: 3.90-59.00) were associated with negative EmE. Moreover, sleeping less than 7 hours per day (OR; 2.26, 95% CI; 1.04-4.90), depressive symptoms (OR = 6.29, 95% CI: 1.27-31.19), anxiety (OR = 14.13, 95% CI: 2.46-80. 97, p<0.01), hypertension (OR = 7.58, 95% CI: 1.24-46.17), and BMI ≥25 (overweight/obese) (OR = 1.51, 95% CI: 1.66-3.41) were associated with negative EmE.

CONCLUSION

The findings show that there is an association between negative EmE, sociodemographic characteristics, physical activity, sleep duration, and mental and physical health in young adults.

Dietary patterns of adolescent students during the COVID-19 pandemic lockdown

This study aimed to analyze the dietary patterns of adolescent students during the COVID-19 pandemic lockdown. To achieve the research´s aim 127 adolescent students, 60 men (18.88±4.18 years) and 67 women (17.61±7.43 years) completed an online questionnaire that analyzed variables regarding their nutritional profile. Adolescent students presented a dietary pattern during the COVID-19 pandemic lockdown characterized by different associations of food consumption, On one hand, the consumption of healthier foods such as meat, fish, vegetables, legumes, rice, or pasta, and on the other hand non-healthier foods as food, alcohol, or pastries. Further investigations are needed to implement multidisciplinary interventions to develop healthier habits in schools and to encourage the adoption of healthy diets among adolescents.

"… because I'm so drunk at the time, the last thing I'm going to think about is calories": Strengthening the argument for Drunkorexia as a food and alcohol disturbance, evidence from a qualitative study

Objectives

Drunkorexia are inappropriate compensatory behaviours in response to alcohol consumption (restricting food intake, excessive exercise, and purging). Past (predominantly quantitative) research shows that Drunkorexia is prevalent in 18–26‐year‐olds, and has significant negative health‐related consequences. There is a debate whether Drunkorexia constitutes an eating or substance disorder, or a Food and Alcohol Disturbance (FAD). To further explore this, and understand underlying motivators, this study utilized qualitative methods.

Design

Qualitative interviews with ten participants (aged 18–26).

Methods

Interviews were analysed with Thematic Analysis.

Results

Three themes were developed: (1) Appearance concerns as motivators, (2) Drunkorexia behaviours to get value for money, and (3) “It’s just a pattern… something I’ve always done”: Drunkorexia as a routine. Results show that Drunkorexia is driven by appearance‐related concerns, such as, wanting to look better/slimmer, engaged in, in relation to an event, such as going out drinking, and carried out despite negative health‐related consequences. However, disregard for compensatory behaviours once drunk was also described, culminating in the consumption of high‐calorie food. This suggests that Drunkorexia is not a persistent pattern of maladaptive behaviour as found in eating or substance use disorders. Wanting value for money (i.e., feeling the maximum intoxication) was described as another reason for Drunkorexia engagement; thus showing that participants consider compensatory behaviours part of their routine of going out drinking.

Conclusions

These result support the view of Drunkorexia as a FAD, rather than an eating or substance use disorder, and show that 18–26‐year‐olds are an at‐risk group for Drunkorexia and its negative health‐related consequences.

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.

Risky Behaviours of Spanish University Students: Association with Mediterranean Diet, Sexual Attitude and Chronotype

The most common drugs that are consumed by young people are alcohol and tobacco, which are especially prevalent in universities. These risk behaviours can be determined by a series of intrinsic and extrinsic factors. The aim of this study was to evaluate the consumption of alcohol and tobacco by Spanish university students and the relationship between the Mediterranean diet, sexual attitudes and opinions, and chronotype. A multicentre observational study enrolled 457 students from two public universities in Spain. The study period was from December 2017 to January 2018. The majority of the participants consumed alcohol (90.2%), tobacco consumption was low (27.2%), with a high percentage of students (78.6%) having a low dependence on nicotine. The surveyed students demonstrated a high adherence to the Mediterranean diet, which was shown to be associated with less risky alcohol consumption. The Mediterranean diet is a part of healthy lifestyle, and avoiding heavy drinking results in the intention to maintain such a lifestyle. In addition, unhealthy eating habits (skipping breakfast, eating sweets and pastries daily, and fast-food consumption) had a tendency to induce risky alcohol consumption. Therefore, to promote healthy lifestyle habits, it is considered important to establish programs that promote healthy diets in university settings and to evaluate them periodically.

'Joining the Dots': Individual, Sociocultural and Environmental Links between Alcohol Consumption, Dietary Intake and Body Weight-A Narrative Review

Alcohol is energy-dense, elicits weak satiety responses relative to solid food, inhibits dietary fat oxidation, and may stimulate food intake. It has, therefore, been proposed as a contributor to weight gain and obesity. The aim of this narrative review was to consolidate and critically appraise the evidence on the relationship of alcohol consumption with dietary intake and body weight, within mainstream (non-treatment) populations. Publications were identified from a PubMed keyword search using the terms 'alcohol', 'food', 'eating', 'weight', 'body mass index', 'obesity', 'food reward', 'inhibition', 'attentional bias', 'appetite', 'culture', 'social'. A snowball method and citation searches were used to identify additional relevant publications. Reference lists of relevant publications were also consulted. While limited by statistical heterogeneity, pooled results of experimental studies showed a relatively robust association between acute alcohol intake and greater food and total energy intake. This appears to occur via metabolic and psychological mechanisms that have not yet been fully elucidated. Evidence on the relationship between alcohol intake and weight is equivocal. Most evidence was derived from cross-sectional survey data which does not allow for a cause-effect relationship to be established. Observational research evidence was limited by heterogeneity and methodological issues, reducing the certainty of the evidence. We found very little qualitative work regarding the social, cultural, and environmental links between concurrent alcohol intake and eating behaviours. That the evidence of alcohol intake and body weight remains uncertain despite no shortage of research over the years, indicates that more innovative research methodologies and nuanced analyses are needed to capture what is clearly a complex and dynamic relationship. Also, given synergies between 'Big Food' and 'Big Alcohol' industries, effective policy solutions are likely to overlap and a unified approach to policy change may be more effective than isolated efforts. However, joint action may not occur until stronger evidence on the relationship between alcohol intake, food intake and weight is established.

Drunkorexia: is it really "just" a university lifestyle choice?

PURPOSE

The current study investigated the prevalence of compensatory behaviours (caloric restriction, increased exercise and bulimic tendencies) in response to alcohol consumption (also known as Drunkorexia) in students, non-students and previous students, as well as beginning to understand the presence of possible predictors of these behaviours (body esteem, sensation seeking).

METHODS

A volunteer sample of students, non-students and previous students (n = 95) completed the Compensatory Eating and Behaviours in Response to Alcohol Consumption Scale, a questionnaire which measures overall Drunkorexia engagement. The participants also completed the Body Esteem Scale for Adolescents and Adults Scale (BESAA) and the Brief Sensation Seeking Scale (BSSS) to investigate predictors of Drunkorexia.

RESULTS

The results indicated that there was no significant difference in Drunkorexia engagement and behaviours between students, non-students and previous students. It was also found that both low body esteem and high sensation seeking tendencies were significant predictors of Drunkorexia; specifically, the appearance esteem factor of the BESAA and the disinhibition factor of the BSSS.

CONCLUSIONS

Findings suggest that Drunkorexia is also present outside of student populations, and therefore, future interventions and research should include non-students in samples. In addition, findings support the idea that Drunkorexia cannot be classified solely as an eating disorder or a substance abuse disorder. As a result of this, further research should be conducted to fully understand why this complex behaviour exists.

Is Alcohol Consumption Related to Lifestyle Factors in Romanian University Students?

Poor eating habits and substance abuse are major public health concerns among young adults transitioning into university life. This study's objective was to assess Romanian students' alcohol consumption and correlate it with other lifestyle factors. We performed a cross-sectional study of 1212 students with a mean age of 21.1 ± 2.4 years. We applied a valid online questionnaire to evaluate and statistically analyze the interrelation between alcohol consumption and lifestyle factors by multivariate statistical analysis. The prevalence of alcohol consumption among the student population enrolled in the study was 79.9%. Multiple regression showed that alcohol consumption was positively associated with gender (p < 0.001), level of physical activity (p = 0.009), number of cigarettes (p < 0.001), and fast-food consumption (p < 0.001), and negatively associated with sleep (p = 0.012) and study hours (p < 0.001). The study revealed a high prevalence (18%) of binge drinking among males. The frequent use of illicit drugs is associated with alcohol consumption (p < 0.001) but present at low levels (1.6%). The study evidenced a high prevalence of alcohol consumption in students, especially in males, and poor food behavior related to the intake of vegetables and fruits. Health promotion campaigns regarding the harmful effects of alcohol, smoking, poor nutrition, and ongoing illicit drug prevention campaigns are needed to improve students' performances.

The case for developing a cohesive systems approach to research across unhealthy commodity industries

OBJECTIVES

Most non-communicable diseases are preventable and largely driven by the consumption of harmful products, such as tobacco, alcohol, gambling and ultra-processed food and drink products, collectively termed unhealthy commodities. This paper explores the links between unhealthy commodity industries (UCIs), analyses the extent of alignment across their corporate political strategies, and proposes a cohesive systems approach to research across UCIs.

METHODS

We held an expert consultation on analysing the involvement of UCIs in public health policy, conducted an analysis of business links across UCIs, and employed taxonomies of corporate political activity to collate, compare and illustrate strategies employed by the alcohol, ultra-processed food and drink products, tobacco and gambling industries.

RESULTS

There are clear commonalities across UCIs' strategies in shaping evidence, employing narratives and framing techniques, constituency building and policy substitution. There is also consistent evidence of business links between UCIs, as well as complex relationships with government agencies, often allowing UCIs to engage in policy-making forums. This knowledge indicates that the role of all UCIs in public health policy would benefit from a common approach to analysis. This enables the development of a theoretical framework for understanding how UCIs influence the policy process. It highlights the need for a deeper and broader understanding of conflicts of interests and how to avoid them; and a broader conception of what constitutes strong evidence generated by a wider range of research types.

CONCLUSION

UCIs employ shared strategies to shape public health policy, protecting business interests, and thereby contributing to the perpetuation of non-communicable diseases. A cohesive systems approach to research across UCIs is required to deepen shared understanding of this complex and interconnected area and also to inform a more effective and coherent response.

College campuses' influence on student weight and related behaviours: A review of observational and intervention research

Research indicates that most college students are not meeting dietary and physical activity guidelines, and the average student gains an estimated 1.6-3.0 kg during 4 years of study. College administrations are well-positioned to influence student weight-related health behaviours by ensuring that campus environments/policies promote health. However, to date, campus health interventions have largely addressed individual and interpersonal factors rather than environmental/policy-level changes. Using an ecological perspective, this narrative review synthesizes the literature on campus environmental/policy-level factors (e.g., food availability, physical activity requirements) associated with student diet, physical activity and weight, as well as campus interventions to address these factors. Web of Science and PubMed databases were searched between December 2018 and November 2019. Results indicate that campus food environments may contribute to overconsumption and weight gain, and the number of campuses requiring students to participate in physical activity courses is in decline. Eight examples of environmental/policy-level campus interventions are presented: nutrition labels in dining halls, campus-wide healthy choice marketing campaigns, restricted payment methods for à la cart dining, trayless dining, health-themed residence halls, peer health education programmes, active classroom spaces and physical activity course requirements. Implications for research and health promotion programmes/policies in the field of college health are discussed.
