Underlying mechanisms in the relationship between stress and alcohol consumption in regular and risky drinkers (MESA): methods and design of a randomized laboratory study

Across the spectrum: Acute alcohol responses in young adults with mild, moderate, and severe alcohol use disorder

BACKGROUND

Little is known about acute subjective and physiological responses to alcohol in individuals with alcohol use disorder (AUD), particularly as it pertains to the spectrum of AUD severity. This study examined acute biphasic alcohol response phenotypes in participants with mild, moderate, and severe AUD.

METHODS

Study data was from the third cohort of the Chicago Social Drinking Project (N = 101, 50 % male; M age=27.1 years). AUD severity was determined based on the DSM-5; 20 % of participants had mild, 20 % had moderate, and 60 % had severe AUD. In a random-order, within-subject, oral alcohol administration paradigm, participants received a high alcohol dose (0.8g/kg), a very high alcohol dose (1.2g/kg), and placebo in separate sessions. Breath alcohol concentration (BrAC), subjective responses (liking, wanting, stimulation, and sedation), and cortisol levels were measured.

RESULTS

Analyses revealed that, relative to those with mild AUD, both very high and high alcohol doses (vs. placebo) significantly increased liking, wanting, and stimulation in the severe AUD subgroup, with a dose-response relationship (very high dose > high dose > placebo) in the moderate AUD subgroup. Alcohol produced lower sedation in participants with moderate and severe AUD relative to mild AUD, suggestive of tolerance to alcohol's sedating and fatiguing effects. Cortisol response to alcohol did not differ across groups, except for higher baseline levels in the severe AUD subgroup, which carried forward.

CONCLUSIONS

Taken together, these findings indicate that higher AUD severity is associated with enhanced sensitivity to alcohol's positive effects, challenging traditional notions of global alcohol tolerance and reward deficit in people who drink excessively.

Cultural and emotional intelligence correlates with healthy lifestyles

A healthy lifestyle is essential to prevent illness and live a happy life. Previous research has shown that social intelligence, such as emotional intelligence (EQ) and cultural intelligence (CQ), is related to a healthy lifestyle. However, there are fewer studies that clarify the relationship between CQ and lifestyle compared to EQ and lifestyle, and the relationship between the facets that make up these intelligences and lifestyle is also unclear. Therefore, in this study, we aimed to clarify the relationship between the eight facets of these intelligences and the seven lifestyles by multiple regression analysis and relative importance analysis. As a result, consistent with the Self-Regulated Learning (SRL) strategy theory, which is based on motivation and metacognition, it was shown that the two intelligences, Use of emotion EQ and Metacognitive CQ, were most broadly correlated with the five lifestyles, and Self-emotional appraisal EQ was also correlated with the two lifestyles. These results suggest that in today's globalized society, in addition to the intelligence required to understand and utilize one's own emotions, there is a need for intelligence to understand different cultures and to verify and correct the accuracy of knowledge about them.

Predictors of Academic Adjustment Among International Students in Rural Southern USA

Academic adaptation is crucial for the success and well-being of international students, especially in rural areas where cultural and social support resources may be limited. This study aimed to identify predictors of academic adaptation among international students in the rural southern United States, focusing on social support, cultural integration, alcohol use, and acculturative stress. A cross-sectional study was conducted with 141 international students from two universities: the University of Mississippi/Oxford campus and the University of Alabama. Data were collected through a web-based survey using validated scales to measure cultural integration, acculturative stress, social support, alcohol use, and academic adaptation. Pearson correlation and multiple linear regression analyses were performed to identify significant predictors of academic adaptation. The sample consisted of 54.6% male and 45.4% female students, with a mean age of 29.4 years. The majority were graduate students (89.4%), with the majority being funded by graduate teaching or research assistantships (78.7%). Correlation analyses showed that social support was positively correlated with academic adaptation (r = 0.62, p < 0.01). Also, cultural integration was positively corelated with academic adaptation (r = 0.33, p < 0.001). However, acculturative stress was negatively correlated with academic adaptation (r = -0.20, p < 0.05). The fully adjusted regression analyses identified social support as a positive predictor of academic adaptation among international students in rural U.S. universities. The model demonstrated that each unit increase in the social support score was associated with a 0.61 increase in the academic adaptation score (95% CI [0.44, 0.79], p < 0.001). These findings highlight the need for tailored support programs addressing the unique challenges faced by this population to enhance their academic success and overall well-being.

Evaluating the synergy: anxiety prevalence and alcohol consumption patterns in high-income countries using Granger causality analysis

BACKGROUND

Alcohol consumption frequently experiences episodes of severe anxiety. This study set out to explore the long-term effects of alcohol consumption on anxiety, revealing insights into how alcohol consumption uniquely impact anxiety, aiming to inform mental health and public health approaches. This research paper explores the complex relationship between the prevalence of anxiety and the consumption patterns of wine, beer, and spirits across fifty-two high-income countries with a continental analysis.

METHOD

By employing significant secondary data taken from the World Health Organization and Our World in Data online databases and covering the period from 1990 to 2019, this study seeks to explore various causality relationships over this period. Its primary objective is to fill the empirical gap in existing research by using Granger causality analysis to reveal the dynamic relationships between the consumption of alcohol and the prevalence of anxiety. This study endeavours to provide a continental analysis of the high-income countries, which allows for including a comprehensive viewpoint in the context of a single investigation.

RESULTS

The findings demonstrate a variety of patterns of causality in alcohol consumption and anxiety prevalence in a one-way causal relationship across specific continents, a bidirectional relationship in others, and no apparent causal relationship in several countries.

CONCLUSION

The inference made from the study's results goes beyond scholarly curiosity; it establishes the foundation for further investigations and the development of customised policies aimed at reducing the mutually reinforcing dangers of alcohol consumption and anxiety disorders.

Association between sociodemographics and change in alcohol or tobacco use behaviors during the COVID-19 pandemic

OBJECTIVE

To examine the association between various sociodemographic factors with alcohol and tobacco use behaviors during the COVID-19 pandemic.

METHODS

Participants from Ohio and Indiana were asked to participate in the 'Impact of COVID-19 on the Cancer Continuum Consortium' study (N = 32,989) from June-November 2020. Those who completed the survey and responded to key study questions were included (n = 5,374). Participants were asked about the frequency and type of alcohol and tobacco product used. Multivariable logistic regression was conducted to determine factors associated with the impact of COVID-19 on change in alcohol and/or tobacco use.

RESULTS

Mean age was 57 years old, 68% were female, 90% non-Hispanic white, 75% married, and 31% lived in rural counties. Out of 5,374 participants, 53% used alcohol-only (n = 2,833), 5% used tobacco-only (n = 255), 7% used both alcohol and tobacco (n = 395), and 35% used neither alcohol nor tobacco (n = 1,891). Urban county of residence (vs. rural) was associated with an increase in alcohol-use (p = 0.0001), change in alcohol products (p = 0.023), and an increase in tobacco use (p = 0.05). Among alcohol-only users, those who were younger (OR = 0.97), female (OR = 1.58), married (OR = 1.69), of high socioeconomic status (OR = 1.99), residing in urban counties (OR = 1.65), and had elevated financial (OR = 1.06) and employment concerns (OR = 1.28) were significantly more likely to report increased alcohol-use. Similarly, among tobacco users, those who were younger (OR = 0.97), female (OR = 2.79), married (OR = 2.16) or divorced (OR = 2.83), and had higher levels of neighborhood disadvantage (OR = 2.19) were significantly more likely to report increased tobacco-use.

CONCLUSIONS

Findings suggest targeted intervention and prevention strategies for young, female participants with elevated financial and employment concerns during the COVID-19 pandemic are necessary to mitigate risks associated with higher odds of alcohol and tobacco use. Our findings on alcohol and tobacco use may be a result of the unique social and economic influence of the pandemic on women.

The ad-libitum taste test as measure of momentary alcohol use in the laboratory: an investigation of construct validity and confounding factors

RATIONALE

The ad-libitum taste test is a widely used covert measure of motivation to consume alcohol in the laboratory. However, studies on its construct validity and potential confounding factors are scarce.

OBJECTIVES

This study aimed to evaluate the construct validity of the ad-libitum taste test by examining the association of ad-libitum alcohol consumption with typical alcohol use and craving, and investigating potential moderation by trait anxiety, depressiveness, current mood, and drinking motives.

METHODS

A sample of 264 young male individuals were offered two 0.33 l glasses of beer. Participants were instructed to rate the characteristics of each drink, while the percentage of beverages containing alcohol consumed was assessed. Associations of ad-libitum consumption with typical alcohol use and craving were assessed using non-parametric and piecewise regressions. Moreover, moderator analysis with trait anxiety, depressiveness, current mood, and drinking motives was carried out.

RESULTS

Ad-libitum alcohol consumption was associated with typical alcohol use and alcohol craving. However, these associations decreased at high consumption levels. Associations between ad-libitum consumption, typical alcohol use, and craving were stable across several conditions, except that the association between ad-libitum consumption and craving increased with higher social, conformity, and coping drinking motives.

CONCLUSIONS

The ad-libitum taste test appears to be a valid measure of the motivation to drink alcohol in laboratory studies in young male adults, although this validity might be compromised at high levels of ad-libitum consumption. Consideration of these factors can contribute to further refining the ad-libitum taste test as a valuable tool for assessing motivation to consume alcohol in laboratory studies.

Emotional, coping factors and personality traits that influenced alcohol consumption in Romanian students during the COVID-19 pandemic. A cross-sectional study

BACKGROUND

During the COVID-19 pandemic, after 3 months from the installation of the state of emergency on the territory of Romania, data were collected from 677 students and master's students, to explore the problematic alcohol consumption (AC).

METHODS

The evaluation was done with: Alcohol Use Disorders Identification Test, Depression, Anxiety and Stress Scales, Strategic Coping Approach Scale and The Freiburg Personality Inventory. The statistical methods used were linear regression with bootstrap procedure, Spearman's rank correlation, and the Mann-Whitney U test.

RESULTS

More than half were affected by depression or anxiety of moderate to extremely severe intensity. The prevalence of problematic alcohol consumption was low: (Hazardous and Extremely Hazardous (2.3) and Medium Risk (10.2). Early onset increases the subsequent risk of problematic AC, compared to women, men recorded a higher AC (p <.01). Anxiety, antisocial action, personality traits Aggressiveness and Somatic complaints had the effect of increasing the alcohol consumption score (p <.01). Significant but weak positive correlations between AC on one hand, and depression, anxiety, stress and antisocial action on the other hand were found (p <.01).

CONCLUSIONS

Probably the prevalence of AC was low as a result of the fact that most respondents were studying in the field of health promotion and as a result of the closure of entertainment venues. This study advocates for the education of youngsters to clearly express their opinions without violating the boundaries of others' feelings (assertive action) and to act prudently in dangerous or uncertain situations (cautious action) since these coping mechanisms were not associated with problematic alcohol consumption. The promotion of positive, achievement-oriented, life attitudes is equally important, as these characteristics of the Life Satisfaction personality dimensions were also found as non-determinants of alcohol-induced problems. The association of problematic AC with antisocial actions as a coping mechanism and high scores on Aggressiveness calls for interventions to educate the younger generation how to acquire and adopt healthy mechanisms to control tensions without resorting to alcohol consumption, more so as the two variables reinforce each other. Drinking as a means of gaining courage must be carefully reconsidered since anxiety generally hits back, often in increased levels.

Inter- and transgenerational heritability of preconception chronic stress or alcohol exposure: Translational outcomes in brain and behavior

Chronic stress and alcohol (ethanol) use are highly interrelated and can change an individual's behavior through molecular adaptations that do not change the DNA sequence, but instead change gene expression. A recent wealth of research has found that these nongenomic changes can be transmitted across generations, which could partially account for the "missing heritability" observed in genome-wide association studies of alcohol use disorder and other stress-related neuropsychiatric disorders. In this review, we summarize the molecular and behavioral outcomes of nongenomic inheritance of chronic stress and ethanol exposure and the germline mechanisms that could give rise to this heritability. In doing so, we outline the need for further research to: (1) Investigate individual germline mechanisms of paternal, maternal, and biparental nongenomic chronic stress- and ethanol-related inheritance; (2) Synthesize and dissect cross-generational chronic stress and ethanol exposure; (3) Determine cross-generational molecular outcomes of preconception ethanol exposure that contribute to alcohol-related disease risk, using cancer as an example. A detailed understanding of the cross-generational nongenomic effects of stress and/or ethanol will yield novel insight into the impact of ancestral perturbations on disease risk across generations and uncover actionable targets to improve human health.

Building a healthy lifestyle: the role of emotional intelligence among Italian university students

Given the numerous evidence demonstrating the influence of emotions in engaging risky behaviors, it seems inevitable to consider new approaches that promote healthy lifestyles. This study examines the relationship between emotional intelligence (EI) and unhealthy lifestyles among undergraduate university students in Southern Italy, since a correlation between EI and harmful health behaviors has been postulated. The present cross-sectional study was conducted among over 18-year-old university students using an online, anonymous, self-administered questionnaire. Socio-demographic characteristics, tobacco use, nicotine dependence, alcohol consumption, and skipping breakfast were investigated. Nearly a third of the sample were current smokers (30.9%). Problematic drinking was shown in 9.9% of the students. Almost one-fourth (23.1%) reported breakfast skipping ≥ 3 days a week. Emotional clarity and total EI scores were significantly lower in current smokers with moderate/high nicotine dependence. Problematic drinking revealed lower emotional clarity and total EI scores. Breakfast skippers showed lower emotional attention and total EI scores. The interconnectedness of unhealthy behaviors and the potential for one behavior to lead to or predict another were  also shown. The study findings provide useful insights to develop evidence-based strategies to empower the young adults to choose a health-promoting lifestyle. The figures suggest that emotional learning interventions could support this goal.

Evaluation of Health Pattern and Stress Levels among Patients Undergoing Alcohol Addiction Treatment-A Cross Sectional Study

Alcohol consumption is linked to over 200 diseases and injuries. It is also classified as a risk factor for several types of neoplasms as well as infectious diseases (i.e., HIV and tuberculosis). In 2019, among people aged 25 to 49, alcohol use was the leading risk factor for attributable burden of disease. There are many factors that affect alcohol drinking patterns such as social and economic status, social norms, cultural customs, availability of alcohol, etc. Stress also plays a significant role in the process of developing alcohol addiction. The aim of our study was to examine health patterns and stress levels among patients undergoing alcohol addiction treatment. The study sample consisted of 104 patients who were treated in a hospital ward due to alcohol dependence. Three standardized questionnaire tools were used to measure the sense of coherence and the level of stress among those patients. The main results suggest that the level of perceived stress correlated negatively with all dimensions of sense of coherence and all indicators of health behaviors, however, age was positively correlated with positive mental attitude, proper eating habits, and health behaviors. In conclusion, it is worth noting that developing patterns for positive health behaviors will make it possible to avoid alcohol dependence or reinforce the treatment results if alcohol dependence syndrome occurs.

Urbanicity and alcohol use epidemiology in the 21st century

PURPOSE OF REVIEW

This review aimed to gather recent studies that could identify the specificities in the relationship between urbanization and alcohol use epidemiology in the current century.

RECENT FINDINGS

Although we find lower rates of alcohol use among adolescents in urban environments than in rural ones, this difference tends to diminish until it disappears by the time they reach adulthood. In addition to excessive marketing and increased accessibility, several urban environment characteristics have been related to alcohol use. First, problematic alcohol use is linked to stress and mental health problems like depression and anxiety, which are common in metropolitan areas. Second, alcohol use behaviors are influenced by homelessness, loneliness, and deprivation in megacities, where female and male individuals have presented more similar alcohol use behaviors (i.e. gender convergence). Third, treatment levels for alcohol use disorders are very low.

SUMMARY

There is a new epidemiological wave of alcohol consumption in large urban centers, largely influenced by advertisement and marketing. Social and psychological risk factors and subpopulations of interest were identified for preventive interventions in large urban centers (i.e. advertisement regulation). In addition, increasing the availability of treatment, including specific medications for alcohol use disorder, should be strongly encouraged.
