Sex differences in associations between delay discounting and expectancies for alcohol analgesia.

Self-medication of pain with alcohol is prevalent, and expectancies for alcohol analgesia likely influence pain relief and alcohol consumption. Hazardous alcohol use has been associated with greater delay discounting rates; however, little is known about the relationship between delay discounting and expectancies for alcohol analgesia. Therefore, the present study examined sex differences in associations between delay discounting and expectancies for alcohol analgesia. Healthy drinkers without chronic pain (N = 53) completed measures of expectancies for alcohol analgesia, alcohol use, and alcohol outcome expectancies. A five-trial adjusting-delay discounting task (DDT) for monetary outcomes was also administered. Regression analyses revealed that sex moderated the relationship between delay discounting and expectancies for alcohol analgesia. Steeper delay discounting rates were associated with weaker expectancies for alcohol analgesia among men when adjusting for average alcohol consumption. Among women, nonsignificant associations between delay discounting rates and expectancies for alcohol analgesia were observed. These findings provide initial evidence of sex differences in associations between delay discounting and expectancies for alcohol analgesia. The directionality of these associations was unexpected and may have implications for patterns of self-medication with alcohol. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Social, psychological and health characteristics associated with stability and change in adult alcohol consumption.

Many studies analyzing health effects of alcohol consumption have operationalized alcohol intake from a single baseline measure without further follow-up. Consequently, there is a lack of knowledge about stability and change in alcohol consumption over the life course and the social, psychological, lifestyle, and health characteristics associated with different alcohol consumption trajectories. The aims of the study were to describe the prevalence of different adult-life alcohol consumption trajectories among Danish men and to analyze social, psychological, lifestyle and health characteristics associated with these trajectories. For 2510 Danish men, retrospective decade-based information on alcohol consumption during life period 26-60 years was obtained in late midlife and information on individual characteristics was obtained in young adulthood, late midlife and from national hospital registries. The men were allocated to one of six a priori defined alcohol consumption trajectories. About 65% of Danish men had a stable moderate consumption, drinking 1-21 units weekly while the five other consumption trajectories were comparatively rare: 3% stable abstainers, 4.7% stable high-risk drinkers, 10.9% with increasing and 12.7% with decreasing consumption. Moderate consumption over the adult life-course was associated with the most favorable social, psychological, lifestyle and health characteristics while the other trajectories were generally associated with less favorable characteristics to varying degrees-e. g. this was the case for the stable abstaining trajectory and in particular the trajectory with decreasing consumption. The findings suggest that the majority of Danish men drink moderately in the life period from young adulthood to late midlife, and deviance from this 'normal' moderate consumption trajectory is associated with less favorable social, psychological, lifestyle and health characteristics. Some of these characteristics may influence alcohol consumption patterns, but for some of the trajectories, alcohol consumption may influence health as well as social and psychological functioning.

Understanding how alcohol environment influences youth drinking: A concept mapping study among university students.

The aim of the study was to identify the environmental factors that influence alcohol consumption, according to university students, and assess the relative importance and the frequency attributed to each factor. A study using Concept Mapping methodology was performed with a sample of nursing students, who participated in two face-to-face data collection sessions. In session 1, a consensus about the environmental aspects that influence their alcohol consumption was obtained. In session 2, the statements obtained were rated according to their relative importance and frequency in alcohol use (1 = minimum; 5 = maximum). Subsequently, all data were analyzed with the RCMAP of the statistical package R 3.6.1.Approximately 60 students participated in each session. Most were women aged 20 to 24. In session 1, a total of 55 statements were obtained and classified into 7 different clusters: Advertising (9 statements); Family environment (4 statements); Social pressure (12 statements); Responsibilities/norms (4 statements); Holidays and leisure time (7 statements); Emotional situations (8 statements); Accessibility (11 statements). Factors related to social pressure, holidays and leisure time, and alcohol accessibility were considered the most important and frequent in alcohol consumption. In contrast, alcohol advertising was considered the least important (mean 2.6 out of 5) and frequent (mean 2.1 out 5) factor. In conclusion, the factors considered most relevant among nursing students match those having more resources allocated for prevention and health promotion, except for alcohol advertising, which was perceived as less important and frequent compared with the other factors.

Excessive alcohol consumption after exposure to two types of chronic social stress: intermittent episodes vs. continuous exposure in C57BL/6J mice with a history of drinking.

The attraction to alcohol can be greatly increased when it is consumed in a social context. While pro-social interactions can potentiate voluntary alcohol drinking under some conditions, aversive social experience (i.e., social stress) can similarly intensify alcohol consumption. We sought to determine how exposure to different types of chronic social stress (i.e., intermittent episodes of social defeat or continuous social stress) influences alcohol consumption and the reinforcing effects of alcohol in mice with a history of drinking. Separate cohorts of male C57BL/6J mice were exposed to either 10days of continuous or intermittent social defeat stress. In experiment 1, mice were assigned to 20% w/v alcohol consumption in a two-bottle choice protocol both prior to and after exposure to social defeat stress. In a second experiment, mice engaged in an operant response sequence to gain access to alcohol wherein completion of a fixed interval (FI; 5min) schedule was reinforced with continuous access to alcohol (fixed ratio; FR1) for up to 1.8g/kg. Alcohol-reinforced responding and subsequent alcohol consumption were assessed daily for 4weeks prior to the 10-day social stress exposure and for 6-week post-stress. Machine learning was implemented to standardize the analysis of defeat behaviors exhibited by the intruder mouse during confrontation with an attacking resident. In mice with a prior history of alcohol drinking, intermittent episodes of social defeat stress produced a significant increase in 20% EtOH consumption in preference over concurrently available water. This increased intake persisted for at least 6weeks after the final social stress experience. Intermittently stressed mice also accelerated their anticipatory responding during the fixed interval component of the operant response chain that was reinforced by alcohol. Neither unstressed controls nor mice exposed to continuous social stress exhibited significant increases in alcohol consumption and alcohol reinforcement. Episodic social defeat stress promotes the seeking and consumption of alcohol, extending earlier work to alcohol-experienced mice. We hypothesize that intermittent access to alcohol and intermittent episodes of social stress are additive and share common sensitizing neural mechanisms that engender excessive alcohol consumption.

The impact of COVID-19 on nurse alcohol consumption: Aqualitative exploration.

Aims and objectivesTo explore the long‐term impact of the COVID‐19 pandemic on nurse alcohol consumption.BackgroundThe COVID‐19 pandemic has caused immense disruption to healthcare services worldwide, and nurses have not been immune, experiencing burnout, declining mental health and ultimately, attrition from the profession. Increases in alcohol consumption have been reported across subsections of society, including those with pre‐existing mental ill health and experiencing high stress, and exploring this phenomenon in nurses is essential for workforce well‐being and sustainability.DesignQualitative descriptive study design.MethodsSecondary analysis of individual, semi‐structured interviews with nurses (N = 42) from diverse settings across Australia, including community, primary and hospital settings, conducted in July and August 2021. Data were analysed using structural coding and reported in accordance with the CORE‐Q guidelines.FindingsTwo key themes were found after analysis of the data: (1) factors influencing alcohol consumption (subthemes: workplace factors and external factors), and (2) the pandemic's influence on alcohol consumption (subthemes: increased consumption, moderation of consumption and alcohol as a reward).ConclusionsSeveral participants described increased alcohol consumption because of the COVID‐19 pandemic, particularly due to the stress of working in an environment where resources were scarce. Workplace factors such as overtime, missed breaks and heightened workload were all described as driving stress, and in turn increased alcohol consumption.Relevance to clinical practiceIncreased alcohol consumption has been associated with burnout, absenteeism and intention to leave. The nursing profession is currently undergoing significant continuing stress providing care and management to patients with the SARS‐CoV‐2 virus, and increased alcohol consumption is a significant threat to personal and workforce well‐being, workforce sustainability and quality nursing care.

The effects of acute alcohol administration on circulating endocannabinoid levels in humans.

Several lines of evidence suggest that endocannabinoid signalling may influence alcohol consumption. Preclinical studies have found that pharmacological blockade of cannabinoid receptor 1 leads to reductions in alcohol intake. Furthermore, variations in endocannabinoid metabolism between individuals may be associated with the presence and severity of alcohol use disorder. However, little is known about the acute effects of alcohol on the endocannabinoid system in humans. In this study, we evaluated the effect of acute alcohol administration on circulating endocannabinoid levels by analysing data from two highly-controlled alcohol administration experiments. In the first within-subjects experiment, 47 healthy participants were randomized to receive alcohol and placebo in a counterbalanced order. Alcohol was administered using an intravenous clamping procedure such that each participant attained a nearly identical breath alcohol concentration of 0.05%, maintained over 3 h. In the second experiment, 23 healthy participants self-administered alcohol intravenously; participants had control over their exposure throughout the paradigm. In both experiments, circulating concentrations of two endocannabinoids, N-arachidonoylethanolamine (AEA) and 2-arachidonoylglycerol (2-AG), were measured at baseline and following alcohol exposure. During the intravenous clamping procedure, acute alcohol administration reduced circulating AEA but not 2-AG levels when compared to placebo. This finding was confirmed in the self-administration paradigm, where alcohol reduced AEA levels in an exposure-dependent manner. Future studies should seek to determine whether alcohol administration has similar effects on brain endocannabinoid signalling. An improved understanding of the bidirectional relationship between endocannabinoid signalling and alcohol intake may deepen our understanding of the aetiology and repercussions of alcohol use disorder.

Factors influencing alcohol consumption in adolescents in Indonesia: A literature study

Factors Associated with Alcohol Consumption among Adolescents in Selected Secondary Schools in a Local Government Area of Oyo State, Southwest, Nigeria

Alcohol use during adolescence and young adulthood remain a prominent public health problem. This study identifies factors associated with alcohol consumption among adolescents in selected secondary schools in Ibadan North Local Government Area, Southwest, Nigeria. A cross-sectional descriptive study was used. One hundred and seventy-six (176) respondents were consecutively selected using the random technique. Data were analyzed using chi-square and hypotheses tested at a 5% level of significance. Findings revealed that the majority of the respondents had poor knowledge of alcohol consumption, while (36.4%) of the respondents had consumed alcoholic beverages. Over half (54.5%) engaged in drinking alcohol as a result of peer influence. The majority (70%) of them had good knowledge of factors influencing alcohol consumption and factors influencing consumption among the respondents. Thus, the rate of alcohol consumption among adolescents was low (36.4%) as a larger percentage (64.6%) of them did not consume alcohol owing to their knowledge of the effect and the presence of some protective factors within the environment. In conclusion, alcohol consumption among adolescents was low, knowledge of its consumption was high, and it was associated with its actual consumption. Alcohol use is also associated with peer influence and environmental variables, while age and gender did not have any relationship with alcohol consumption. Therefore, educational intervention to improve knowledge of the consequences of alcohol consumption among adolescents and public policies with preventive educational campaigns was recommended.

Craving mediates the association between attentional bias to alcohol and in vivo alcoholic beverage consumption in young social drinkers.

Franken's attentional bias hypothesis proposes that attentional bias to alcohol (ABA) activates craving, which motivates alcohol consumption behavior. While this hypothesis was put forward to account for alcohol dependence, the present study tested whether Franken's model may potentially contribute to explaining variation in beer consumption among young social drinkers.ABA was measured by presenting participants with dual videos, one showing alcoholic beverages and the other non-alcoholic beverages, and assessing relative attention to each using a visual probe procedure. Self-reported alcohol craving was assessed four times over the session. In vivo alcoholic beverage consumption was assessed by the remaining weight of alcohol bottle following consumption, measured at conclusion of the experiment.The study revealed that ABA positively predicted alcohol craving (p < .01) and in vivo beer consumption (p < .01). The relationship between ABA and beer consumption was fully mediated by craving (β = .63, 95% CI [.04, 1.29]).To our knowledge, this is the first study to show that the relationship between ABA and in vivo alcoholic beverage consumption is fully mediated by alcohol craving. Future research can extend understanding of the causal relationship between ABA, craving, and consumption, by determining whether direct modification of ABA influences alcohol consumption by altering craving.

The association between unemployment trajectories and alcohol consumption patterns. Evidence from a large prospective cohort in The Netherlands.

Unemployment is expected to influence alcohol consumption, but studies show mixed results, partly because most studies concentrate on current employment status. However, unemployment could be particularly consequential if it is part of a trajectory of employment precariousness. Moreover, the association between unemployment and alcohol consumption may not be homogeneous across the population, but differ by subgroups (e.g. socioeconomic status). This study longitudinally analyses the association between different employment trajectories and alcohol consumption, and examines if the association is moderated by socioeconomic status (SES), partner status, age and gender. Four waves of data of the Lifelines Cohort study are used. Sample consists of individuals from 18-50 years old, active in the labor market (n = 104,766) from the northern provinces of the Netherlands. Employment trajectories are defined by employment status in each wave, duration of unemployment, and number of exposures to unemployment. Drinking patterns are divided into "abstainers", "moderate drinking" (<1.5 drinks/day), "heavy drinking" (≥1.5 drinks/day) and "binge drinking" (≥5 drinks/occasion; 4 for women). The associations are estimated with multinomial logistic regression models. Results show that recent, long-term unemployment (≥ 6 months) is associated with higher rates of heavy drinking (RRR = 1.26 [95 % CI 1.03-1.54]), whereas short-term unemployment does not show any association with the outcome. Being continuously unemployed throughout the observation period shows a strong association with binge drinking (RRR = 1.43 [95 % CI 1.06-1.93]), as well as reporting 2 or more long unemployment spells (RRR = 1.49 [95 % CI 1.21-1.83]). The group of abstainers (77.95 % women) have significantly lower SES, and poorer health than their peers. For some individuals, recent unemployment increases the likelihood for abstinence (RRR = 1.23 [95 % CI 1.00-1.51]). Evidence suggests that length of unemployment is key in order to grasp its effects in terms of changing drinking patterns.

Voluntary Adolescent-Onset Alcohol Drinking Fails to Influence Alcohol Consumption or Anxiety-Like Behaviour in Adulthood in Female Alcohol-Preferring Rats.

AimsAlcohol exposure during adolescence is associated with both increased risk for alcohol use disorders and anxiety in adulthood. Our present experiments examined this association using alcohol-preferring AA (Alko Alcohol) rats selected for high voluntary alcohol drinking.MethodsTwo groups of female AA rats acquired alcohol drinking at different ages. We gave the adolescent-onset group free choice to 10% alcohol and water for seven weeks, starting on post-natal day 42 (PND 42), whereas the adult-onset group started drinking alcohol on PND 112. After the 7-week drinking, we withdrew the adolescent group from alcohol for two weeks, followed by another voluntary 7-week drinking period, started at the same age as the adult-onset group. We assessed anxiety-like behaviour repeatedly during alcohol drinking with open field and elevated plus maze tests. At the end of alcohol drinking, we also tested the rats using the light/dark box, stress-induced body temperature test and social dominance test.ResultsDuring the first 7-week alcohol drinking, adolescent rats exhibited significantly slower acquisition of alcohol drinking and lower alcohol preference than the adult-onset group. However, when tested at the same age as the adult-onset rats, they displayed identical alcohol intake and preference. We found no alcohol-induced effects on anxiety- or stress-related behaviour in the experimental groups at any time points.ConclusionsThese data show that the genetically determined phenotype of high alcohol drinking of the female alcohol-preferring AA rats is not associated with a predisposition to develop anxiety-like behaviour following voluntary alcohol exposure, even when initiated during adolescence.

Changes in perceptions of the alcohol environment among participants in a Photovoice project conducted in two districts with different socio-economic status.

Perceptions of the alcohol environment may influence alcohol consumption patterns. The purpose of this study was to describe changes in perceptions of the urban alcohol environment as experienced by residents of two districts with different socio-economic status after taking part in a Photovoice study. The study was conducted in Madrid, Spain, in a district with a high socio-economic status (HSES) and another district with a low socio-economic status (LSES). A Photovoice project was conducted with 26 participants divided into four groups based on sex and district. Groups met over five sessions in which they discussed photographs taken by the participants themselves on the subject of alcohol in their neighbourhood. A qualitative, descriptive and thematic analysis of participants’ discourses was performed to explore changes in their perceptions of the alcohol environment over the project sessions. Changes in perceptions of the alcohol environment were observed in all groups over the project. The process of change varied by districts’ socio-economic characteristics and gender. Greater changes in perceptions of the alcohol environment were observed in HSES, especially among women, as the participants had a much more positive initial view of their alcohol environment. In LSES, participants showed a more critical perception of the alcohol environment from the beginning of the study, and this broadened and intensified over the course of the sessions. Changes in perceptions also varied by thematic categories, including some categories that were discussed from the start (e.g. socialising and alcohol consumption) and categories that only emerged in later sessions (e.g. alcohol advertising). Involvement in a Photovoice project has favoured a shift in the participant’s perceptions of their alcohol environment towards more critical positions, widening their scope of perceived elements and raising their awareness of specific problems, such as alcohol advertising and social role of alcohol consumption in relation to alcohol exposure.

Low but not moderate amounts of caffeine increase co-consumption of ethanol in C57BL/6J mice

The increasingly popular combination of “energy drinks” containing high amounts of caffeine and alcohol has been shown to induce a stimulated, rather than sedated, state which may result in increased binge drinking and increased risk for alcohol-attributable accidents. We sought to examine consumption patterns of and withdrawal from alcohol and caffeine using a voluntary co-consumption animal model. Male and female adult C57BL/6J mice were given access to increasing doses of caffeine (0.01–0.05%) and/or alcohol (3–20%) in a two-bottle choice, intermittent access voluntary paradigm with fluid consumption recorded daily. Anxiety-like behavior during withdrawal was assessed via elevated plus maze or open field test in experiment 2. Increasing both alcohol and caffeine simultaneously in Experiment 1 resulted in no significant changes in co-consumption compared to mice given access to only alcohol or caffeine. Experiment 2 held caffeine concentration steady while slowly increasing alcohol content and resulted in mice consuming more alcohol when it was consumed in tandem with low dose caffeine. Both male and female mice consumed more caffeine when it was paired with alcohol; however, no significant differences were observed during withdrawal behavior. These results suggest that caffeine may dose-dependently positively influence alcohol consumption in mice and echo clinical literature suggesting that caffeine and alcohol together may result in a heightened state of stimulation and lead to further binge drinking. The intermittent access paradigm affords increased translational validity regarding investigations of alcohol and caffeine co-consumption and may be useful in identifying the neurobiological mechanisms concerning co-consumption of such substances.

Perceived Stress as A Mediator in The Relationship between Time Perspectives and Alcohol Consumption

Heavy drinking is injurious to health and may even lead to death. Previous studies showed that Past-Negative, Present-Fatalistic, and Future time perspectives influence alcohol consumption; however, this study presents evidence that contradicts these claims. Lazarus and Folkman’s (1984) transactional model of stress and coping explains that cognitive processes, such as perceived stress, are responsible for individual choices of coping strategies or decision to consume alcoholic beverages. Personal factors also influence time perspectives. This study applies the aforementioned model to hypothesize that the relationship between time perspectives and alcohol consumption is mediated by perceived stress. A total of 307 participants aged 18–22 years (late adolescence) who were habitual consumers of alcohol participated in this study. Mediation analysis was employed and it was revealed that perceived stress did not mediate the relationship between Past-Negative and Present-Fatalistic time perspectives and alcohol consumption. However, perceived stress was found to be a mediator in the relationship between Future time perspective and alcohol consumption. To summarize, dominant Past-Negative and Present-Fatalistic time perspectives can cause alcohol consumption in individuals who possess specific characteristics. Conversely, stress can precipitate alcohol consumption for individuals evincing the Future time perspective.

Patterns of alcohol consumption in european pregnant women with alcohol use disorder

IntroductionPrenatal alcohol exposure can have a negative impact on a child’s neurocognitive development. Still, about 16% of European women maintain alcohol consumption, even after knowing they are pregnant. Several studies have shown that alcohol use patterns alter drastically during pregnancy. However, little is known about how these change in women with Alcohol Use Disorder (AUD) diagnosis.ObjectivesTo understand the impact of pregnancy on alcohol use patterns in women at high risk or with previous AUD diagnosis.MethodsBibliographic research was made through the PubMed/NCBI database. No time limit was specified on the search. Pertinent manuscripts were individually reviewed for additional relevant citations.ResultsSeveral factors influence alcohol consumption during pregnancy, including financial status, educational level, and high levels of psychological stress. Although older age at the onset of pregnancy is deemed a risk factor for alcohol consumption, women of 25 or fewer years of age are at higher risk for AUD, as are those with a history of criminal behaviour and family history of AUD. Pregnancy seems to play a critical role in altering alcohol use patterns, reducing the risk of AUD in about 70%, regardless of pregnancy trimester. This is seen even in women who present high-risk factors for AUD.ConclusionsPregnancy presents itself as a behavioural change promoter and should be regarded as a window of opportunity for intervention in women with AUD. However, there are few studies that focus on alcohol consumption patterns specifically in women with AUD, whereby making it necessary to extrapolate the available data.

Alcohol Consumption during a Pandemic Lockdown Period and Change in Alcohol Consumption Related to Worries and Pandemic Measures.

Whether lockdown related to the COVID-19 pandemic influences alcohol consumption is not well known. This study assesses alcohol consumption and hazardous drinking behavior during the initial phase of pandemic measures in Norway and identifies potential risk factors. A cross-sectional study (N = 25,708) was conducted in Bergen, Norway, following the first six weeks of strict infection control measures. In a model of self-assessed increased alcohol consumption, logistic regression analysis was conducted with independent variables for COVID-19-related worries, joblessness, quarantine, self-reported drinking behavior, age, gender, and occupational situation. These are reported with odds ratios (ORs) with 95% confidence intervals. Fifty-one percent of respondents reported economic or health-related worries due to COVID-19, 16% had been in quarantine, 49% worked/studied from home, 54% reported hazardous drinking behavior, and 13% reported increased alcohol consumption. People aged 30–39 years had elevated odds of increased alcohol consumption during lockdown (OR 3.1, 2.4−3.8) compared to the oldest adults. Increased drinking was more frequent among people reporting economic worries (OR 1.6, 1.4−1.8), those quarantined (OR 1.2, 1.1−1.4), and those studying or working at home (OR 1.4, 1.3−1.6). More than half of respondents reported hazardous drinking behavior. Increased alcohol consumption during lockdown was common among people with economic worries, people in quarantine, and people studying or working at home. These data could be important when adjusting pandemic measures.

Temperament and character of patients with alcohol toxicity during COVID \u2212\u200919 pandemic

BackgroundCorona virus epidemic may be acts as a stressor or trauma that affects both physical health and mental health. People exhibited various reactive behaviors to confront with this stressful situation. In Iran, one of the common motives for alcohol consumption is to scape problems and cope with stresses. It has been shown that personality factors influence alcohol consumption, since they are associated with drinking motives. The main purpose of this study was to investigate the correlation between temperament and character and alcohol abuse.MethodsThis cross-section study was conducted on 135 alcohol intoxicated patients admitted to emergency room in March 2020 and 255 participants who were randomly selected from public in Shiraz. A questionnaire consisted of TCI (Temperament and character inventory) and several questions about COVID-19 pandemic. It was completed by a trained interviewer using the matched answer technique. Demographic factors were self-reported.ResultsAmong the alcohol intoxicated group, 117 (86.7%) were males and 18(13.3%) were females. The mean age of the participants was 32.43 ± 10.81 years. Among control group, 99 (38.8%) were males and 156 (61.2%) were females. The mean age of control group was 33.12 ± 14.77 years. Alcohol toxicity was mostly observed among the young males (male/female ratio was 6.45). According to temperament and character index, mean scores of novelty seeking, harm avoidant, and self-transcendence were higher in the alcohol toxicity group than normal population (P < 0.01). Mean scores of reward dependent, cooperativeness, and self-directedness were higher in normal population than the alcohol toxicity group (P < 0.001). The mean score of persistence was not significantly different between methanol intoxicated and normal population groups (P = 0.718).ConclusionAlcohol intoxicated patients had higher scores of novelty-seeking and self-transcendence and lower scores of reward-dependency scores, cooperativeness and self-directedness. These scores are associated with higher likelihood of personality disorders.

Applying a complex systems perspective to alcohol consumption and the prevention of alcohol-related harms in the 21st century: a scoping review.

A complex systems perspective has been advocated to explore multi-faceted factors influencing public health issues, including alcohol consumption and associated harms. This scoping review aimed to identify studies that applied a complex systems perspective to alcohol consumption and the prevention of alcohol-related harms in order to summarize their characteristics and identify evidence gaps. Studies published between January 2000 and September 2020 in English were located by searching for terms synonymous with 'complex systems' and 'alcohol' in the Scopus, MEDLINE, Web of Science and Embase databases, and through handsearching and reference screening of included studies. Data were extracted on each study's aim, country, population, alcohol topic, system levels, funding, theory, methods, data sources, time-frames, system modifications and type of findings produced. Eighty-seven individual studies and three systematic reviews were identified, the majority of which were conducted in the United States or Australia in the general population, university students or adolescents. Studies explored types and patterns of consumption behaviour and the local environments in which alcohol is consumed. Most studies focused on individual and local interactions and influences, with fewer examples exploring the relationships between these and regional, national and international subsystems. The body of literature is methodologically diverse and includes theory-led approaches, dynamic simulation models and social network analyses. The systematic reviews focused on primary network studies. The use of a complex systems perspective has provided a variety of ways of conceptualizing and analyzing alcohol use and harm prevention efforts, but its focus ultimately has remained on predominantly individual- and/or local-level systems. A complex systems perspective represents an opportunity to address this gap by also considering the vertical dimensions that constrain, shape and influence alcohol consumption and related harms, but the literature to date has not fully captured this potential.

Análisis de las redes sociales en el consumo de alcohol

El consumo de alcohol se ha convertido en un problema grave de salud, en la actualidad, entre los jóvenes de 14 y 30 años. El objetivo del presente trabajo fue analizar la comunicación en redes sociales en relación al consumo de alcohol. Durante el periodo de tiempo descrito se recopilaron un total de 2063 comentarios de Twitter. Los resultados muestran las diferentes opiniones que tienen los usuarios, los medios divulgativos, así como la policía o los grupos de protesta sobre la ingesta de alcohol. De modo, que la mayoría de jóvenes apoyan el consumo de alcohol como forma de divertirse, mientras que la policía, los grupos de protesta y los medios de divulgación muestran a la sociedad y concretamente a los jóvenes las consecuencias que tiene el consumo. Como conclusión, cabe destacar como las redes sociales se han convertido en la nueva forma de comunicarse entre los jóvenes, lo que facilita el intercambio de opiniones, ideas e información a nivel mundial. Así, han posibilitado observar como las redes sociales influyen en el consumo y la prevención del alcohol, por tanto, las redes pueden ser utilizadas como herramientas para realizar campañas y programas de prevención del consumo de alcohol en los jóvenes, reduciendo la ingesta del mismo.

Depression, Alcoholics Anonymous Involvement, and Daily Drinking Among Patients with co-occurring Conditions: A Longitudinal Parallel Growth Mixture Model.

Patients with cooccurring mental health and substance use disorders often find it difficult to sustain long-term recovery. One predictor of recovery may be how depression symptoms and Alcoholics Anonymous (AA) involvement influence alcohol consumption during and after inpatient psychiatric treatment. This study utilized a parallel growth mixture model to characterize the course of alcohol use, depression, and AA involvement in patients with cooccurring diagnoses. Participants were adults with cooccurring disorders (n=406) receiving inpatient psychiatric care as part of a telephone monitoring clinical trial. Participants were assessed at intake, 3-, 9-, and 15-month follow-up. A 3-class solution was the most parsimonious based upon fit indices and clinical relevance of the classes. The classes identified were high AA involvement with normative depression (27%), high stable depression with uneven AA involvement (11%), and low AA involvement with normative depression (62%). Both the low and high AA classes reduced their drinking across time and were drinking at less than half their baseline levels at all follow-ups. The high stable depression class reported an uneven pattern of AA involvement and drank at higher daily frequencies across the study timeline. Depression symptoms and alcohol use decreased substantially from intake to 3months and then stabilized for 90% of patients with cooccurring disorders following inpatient psychiatric treatment. These findings can inform future clinical interventions among patients with cooccurring mental health and substance use disorders. Specifically, patients with more severe symptoms of depression may benefit from increased AA involvement, whereas patients with less severe symptoms of depression may not.
