Binge Drinking, Other Substance Use, and Concurrent Use in the U.S., 2016-2018

Brain correlates and functional connectivity linking stress, autonomic dysregulation, and alcohol motivation

High stress is a key risk factor for alcohol use disorder (AUD) and often accompanied by physiological dysregulation including autonomic nervous system (ANS) disruptions. However, neural mechanisms underlying drinking behaviors associated with stress and ANS disruptions remain unclear. The current study aims to understand neural correlates of stress, ANS disruptions, and subsequent alcohol intake in social drinkers with risky drinking. Using functional magnetic resonance imaging (fMRI), we investigated brain and heart rate (HR) autonomic responses during brief exposure to stress, alcohol, and neutral cues utilizing a well-validated, individualized imagery paradigm in 48 social drinkers of which 26 reported high-risk drinking (HD) while 22 reported low-risk drinking (LD) patterns. Results indicated that HD individuals showed stress and ANS disruptions with increased basal HR, stress-induced craving, and decreased brain response to stress exposure in frontal-striatal regions including the ventromedial prefrontal cortex (VmPFC), anterior cingulate cortex, striatum, insula, and temporal gyrus. Furthermore, whole-brain correlation analysis indicated that greater basal HR was associated with hypoactive VmPFC, but hyperactive medulla oblongata (MOb) responses during stress, with an inverse association between activity in the VmPFC and Mob (whole-brain corrected (WBC), p < 0.05). Functional connectivity with the MOb as a seed to the whole brain indicated that HD versus LD had decreased functional connectivity between the VmPFC and MOb during stress (WBC, p < 0.05). In addition, those with more compromised functional connectivity between the VmPFC and MOb during stress consumed greater amount of alcohol beverage during an experimental alcohol taste test conducted on a separate day, as well as in their self-reported weekly alcohol intake. Together, these results indicate that stress-related, dysfunctional VmPFC control over brain regions of autonomic arousal contributes to greater alcohol motivation and may be a significant risk factor for hazardous alcohol use in non-dependent social drinkers. Findings also suggest that restoring VmPFC integrity in modulating autonomic arousal during stress may be critical for preventing the development of AUD.

Neural correlates of increased alcohol demand following alcohol cue exposure in adult heavy drinkers

Alcohol use disorder is associated with overvaluation of alcohol relative to other rewards, in part due to dynamic increases in value in response to alcohol-related cues. In a neuroeconomic framework, alcohol cues increase behavioral economic demand for alcohol, but the neural correlates these cue effects are unknown. This functional magnetic resonance imaging study combined a neuroeconomic alcohol purchase task with an alcohol cue exposure in 72 heavy drinkers with established sensitivity to alcohol cues (51 % female; mean age=33.74). Participants reported how many drinks they would consume from $0-$80/drink following exposure to neutral and alcohol images in a fixed order. Participants purchased significantly more drinks in the alcohol compared to the neutral condition, which was also evident for demand indices (i.e., intensity, breakpoint, Omax, elasticity; ps<0.001; ds=0.46-0.92). Alcohol purchase decisions were associated with activation in rostral middle and medial frontal gyri, anterior insula, posterior parietal cortex, and dorsal striatum, among other regions. Activation was lower across regions in the alcohol relative to neutral cue condition, potentially due to greater automaticity of choices in the presence of alcohol cues or attenuation of responses due to fixed cue order. These results contribute to growing literature using neuroeconomics to understand alcohol misuse and provide a foundation for future research investigating decision-making effects of environmental alcohol triggers.

Alcohol Consumption and Illicit Drug Use: Associations With Fall, Fracture, and Acute Health Care Utilization Among People With HIV Infection

BACKGROUND

Given alcohol and/or other drug (AOD) use occurs among people with HIV (PWH), we examined its association with falls and fall-related outcomes and whether frailty moderates the association.

SETTING

Northeastern US city.

METHODS

We analyzed an observational cohort of PWH with current or past AOD use. Alcohol measures were any past 14-day heavy use, average alcohol/day, and days with heavy use. Drug use measures were past 30-day illicit use of cocaine, opioids, and sedatives. Repeated cross-sectional associations were estimated with separate multivariable generalized estimating equation regression models for each fall-related outcome.

RESULTS

Among PWH (n = 251; mean age 52 [SD = 10]), 35% reported heavy alcohol use, 24% cocaine, 16% illicit opioids, 13% illicit sedatives, and 35% any fall; 27% were frail. Heavy alcohol use was associated with a fall (AOR = 1.49, 95% CI: 1.08 to 2.07), multiple falls (AOR = 1.55 95% CI: 1.10 to 2.19), and fall/fracture-related emergency department visit or hospitalization (AOR = 1.81, 95% CI: 1.10 to 2.97). Higher average alcohol/day and more heavy drinking days were associated with multiple falls. Illicit sedative use was associated with a fall, multiple falls, and emergency department visit/hospitalization and opioid use with fracture. Frailty moderated the association of heavy alcohol use and a fall (AOR = 2.26, 95% CI: 1.28 to 4.01 in those frail) but not in those not frail.

CONCLUSION

The effect of AOD use on falls and fall-related outcomes was most pronounced with alcohol, particularly among frail PWH. Heavy alcohol, illicit sedative, and illicit opioid use are high-priority targets for preventing falls and fall-related consequences for PWH.

Analytical description of adolescent binge drinking patients

BACKGROUND

Binge drinking is a widespread health compromising behavior among adolescents and young adults, leading to significant health problems, injuries and mortality. However, data on alcohol consumption is often unreliable, as it is mainly based on self-reporting surveys. In this five-year study (2014-2019) at the University Children's Hospital Zurich, we analyzed blood samples from adolescent binge drinking patients to investigate blood alcohol concentrations (BACs), co-ingestion of drugs, assess compliance between self-reported and measured substance use, and test for genetic components of innate alcohol tolerance. Furthermore, hair analysis was performed to retrospectively access drug exposure and to evaluate the potential of hair analysis to assess binge drinking.

METHODS

In a prospective, single-center study, patients with alcohol intoxications aged 16 years and younger were included. Blood and hair samples were analyzed by sensitive liquid chromatography - tandem mass spectrometry drug analysis. HTTLPR genotyping was performed with PCR and fragment analysis.

RESULTS

Among 72 cases, 72 blood and 13 hair samples were analyzed. BACs ranged from 0.08-3.20‰ (mean 1.63‰, median 1.60‰), while a mean concentration of 3.64 pg/mg hair (median 3.0 pg/mg) of the alcohol marker ethyl glucuronide (EtG) was detected in eleven hair samples, providing no evidence of chronic excessive drinking. In 47% of the cases, co-ingested drugs were qualitatively detected next to ethanol, but only 9% of the detected drugs had blood concentrations classified as pharmacologically active. Cannabis consumption (22%) and stimulant intake (16%) were the most frequently observed drugs. Compliance between patients' statements and measured substances matched well. Although we investigated the genetic contribution to innate alcohol tolerance via the 5-HTTLPR polymorphism, the diverse genetic background of the cohort and small sample size did not allow any conclusions to be drawn.

CONCLUSION

Almost half of our binge drinking patients tested positive for other substances, primarily cannabis. We anticipate that our study enhances understanding of consumption behavior of young people and encourage continued efforts to address the harmful effects of binge drinking and co-occurring substance use.

Predictors of polysubstance use in patients with severe alcohol use disorder: the role of reward craving

BACKGROUND

Different craving typologies (i.e., reward, relief, obsessive) have been identified in alcohol use disorder (AUD) but have been less investigated in specific populations like AUD patients with polysubstance use (PSU). The role of dysfunctional personality traits and reward pathways has been reported in both AUD and PSU. We hypothesized that patients with AUD-PSU might show a prevalent reward craving, alongside specific sociodemographic, clinical, and personality features, and aimed at investigating differences in 423 severe AUD outpatients with and without PSU.

METHODS

One hundred fifteen patients (27.1% of the sample, 67% males, 42 ± 11.6 years old) displayed PSU. Sociodemographic, clinical features and psychopathological/personality dimensions were assessed through: Craving Typologies Questionnaire (CTQ); Obsessive-Compulsive Drinking Scale (OCDS); UPPS-P Impulsive Behavior Scale (S-UPPS-P); Difficulties in Emotion Regulation Scale (DERS). A binomial logistic regression explored factors associated with PSU.

RESULTS

We found higher CTQ 'reward' scores (p < 0.001) in AUD-PSU patients, and a significant association between reward craving and PSU through logistic regression (OR:1.13; p = 0.005). Earlier AUD onset (p < 0.001), greater rates of binge drinking (p = 0.029), more legal problems (p = 0.015), but no significantly higher S-UPPS-S and DERS scores, were detected in AUD-PSU patients.

CONCLUSIONS

Reward craving was associated with increased risk for PSU in severe AUD patients. Given AUD-PSU participants greater severity and detrimental treatment responses imputed to PSU, identifying prevalent craving types among risk factors for PSU in AUD may help to implement therapeutic strategies. Addressing neurobiological and behavioral mechanisms through combined psychotherapies, pharmacological and neuromodulation treatments could support tailored interventions with better long-term outcome.

Risky business: an examination of drinking games in college settings and their impact: a systematic review

This systematic review explores the prevalence and impact of Drinking Games (DG) among college students. DGs involve social drinking with the goal of heavy alcohol consumption and are associated with risky behaviours. The review aims to quantify the relationship between DG participation, alcohol consumption, and negative outcomes. It also investigates gender moderation and unexplored motivational factors for DG engagement. Following PRISMA guidelines, 34 studies were included after screening 317 records. The studies comprised n = 34,197 participants and were analysed for various variables, including gender dynamics, motivations, and associated negative consequences. Gender convergence in DG participation was noted, emphasizing the importance of gender-specific interventions. Participants were aware of risks but often perceived negative outcomes as a badge of honour. Motivations for DGs were linked to social interaction and a sense of belonging. Personality traits like sensation seeking and identification with college drinking culture played significant roles in DG engagement and outcomes. The review underscores the need for targeted interventions to address shifting perceptions of negative consequences and consider personality traits when designing preventive measures. It also highlights the significance of gender-specific strategies. However, variations in DG measurement and possible selection bias among heavy drinkers participating in DGs remain limitations. This systematic review provides insights into DG prevalence and its link to negative outcomes among college students. The findings stress the importance of tailored interventions and further research to mitigate risk factors and promote healthier drinking behaviours in this demographic.

Alcohol Use Among Treatment-Seeking Individuals With Opioid Use Disorder

OBJECTIVE

Individuals in the United States with opioid use disorder (OUD) have high rates of co-occurring alcohol use disorder. However, there is limited research on co-use patterns among opioid and alcohol use. The present study examined the relationship between alcohol and opioid use in treatment-seeking individuals with an OUD.

METHOD

The study used baseline assessment data from a multisite, comparative effectiveness trial. Participants with an OUD who had used nonprescribed opioids in the last 30 days (n = 567) reported on their alcohol and opioid use during the past 30 days using the Timeline Followback. Two mixed-effects logistic regression models were used to assess the effect of alcohol use and binge alcohol use (≥4 drinks/day for women and ≥5 drinks/day for men) on opioid use.

RESULTS

The likelihood of same-day opioid use was significantly lower on days in which participants drank any alcohol (p < .001) as well as on days in which participants reported binge drinking (p = .01), controlling for age, gender, ethnicity, and years of education.

CONCLUSIONS

These findings suggest that alcohol or binge alcohol use is associated with significantly lower odds of opioid use on a given day, which was not related to gender or age. The prevalence of opioid use remained high on both alcohol use and non-alcohol use days. In line with a substitution model of alcohol and opioid co-use, alcohol may be used to treat symptoms of opioid withdrawal and possibly play a secondary and substitutive role in individuals with OUD substance use patterns.

Initial Validation of the Intentions to Co-Use Alcohol and Opioids Scale

Co-use of alcohol and prescription opioid medication increases risk for harmful and potentially fatal health effects (e.g., overdose). Behavioral intentions (i.e., the immediate antecedent of corresponding behavior according to the Theory of Planned Behavior) are important in prediction of substance use, and a valid measure assessing intentions to co-use alcohol and opioids is needed to identify individuals at-risk for harmful substance use. The goal of the current study was to develop and conduct the psychometric validation of a six-item Intentions to Co-Use Alcohol and Opioids (ICAO) scale. Participants included 261 (Mage = 38; 64% male) past-month drinkers with a current opioid prescription and chronic musculoskeletal pain who completed a targeted online survey. Confirmatory factor analysis indicated that a single-factor structure provided good model fit (Bollen-Stine bootstrap p = .121). Moreover, the ICAO demonstrated high internal consistency (α = .96) and was correlated with measures of alcohol and opioid use/co-use. These findings provide support for the single-factor structure, reliability, and concurrent/convergent validity of the ICAO among individuals who endorse alcohol use, opioid use, and chronic musculoskeletal pain. The ICAO may offer clinical utility as a tool to identify individuals at greater risk of potentially fatal co-use of alcohol and opioid medications.

Alcohol and Other Substance Use Before and During the COVID-19 Pandemic Among High School Students - Youth Risk Behavior Survey, United States, 2021

Adolescence is a critical phase of development and is frequently a period of initiating and engaging in risky behaviors, including alcohol and other substance use. The COVID-19 pandemic and associated stressors might have affected adolescent involvement in these behaviors. To examine substance use patterns and understand how substance use among high school students changed before and during the COVID-19 pandemic, CDC analyzed data from the nationally representative Youth Risk Behavior Survey. This report presents estimated prevalences among high school students of current (i.e., previous 30 days) alcohol use, marijuana use, binge drinking, and prescription opioid misuse and lifetime alcohol, marijuana, synthetic marijuana, inhalants, ecstasy, cocaine, methamphetamine, heroin, and injection drug use and prescription opioid misuse. Trends during 2009-2021 were assessed using logistic regression and joinpoint regression analyses. Changes in substance use from 2019 to 2021 were assessed using prevalence differences and prevalence ratios, stratified by demographic characteristics. Prevalence of substance use measures by sexual identity and current co-occurring substance use were estimated using 2021 data. Substance use prevalence declined during 2009-2021. From 2019 to 2021, the prevalence of current alcohol use, marijuana use, and binge drinking and lifetime use of alcohol, marijuana, and cocaine and prescription opioid misuse decreased; lifetime inhalant use increased. In 2021, substance use varied by sex, race and ethnicity, and sexual identity. Approximately one third of students (29%) reported current use of alcohol or marijuana or prescription opioid misuse; among those reporting current substance use, approximately 34% used two or more substances. Widespread implementation of tailored evidence-based policies, programs, and practices likely to reduce risk factors for adolescent substance use and promote protective factors might further decrease substance use among U.S. high school students and is urgently needed in the context of the changing marketplaces for alcohol beverage products and other drugs (e.g., release of high-alcohol beverage products and increased availability of counterfeit pills containing fentanyl).

Effectiveness of text message interventions with different behavior change techniques on alcohol consumption among young adults: a five-arm randomized controlled trial

AIMS

This studys aim is to test the effectiveness of five interventions each utilizing a unique set of behavior change techniques on reducing alcohol consumption at 3 and 6 months among young adults with hazardous drinking.

DESIGN, SETTING AND PARTICIPANTS

This study used a five-arm parallel randomized controlled trial with 3- and 6-month follow-ups. Recruitment occurred at four emergency departments in Pittsburgh, PA, USA. Participants were non-treatment-seeking young adults (mean age = 22.1 years; 68.5% female; 37.1% black) who reported hazardous drinking.

INTERVENTIONS

Participants were randomized to one of five automated text message interventions for 12 weeks that interacted with participants on the 2 days per week that they typically drank: assisted self-monitoring (TRACK: control condition; n = 245), pre-drinking cognition feedback (PLAN; n = 226), alcohol consumption feedback (USE; n = 235), adaptive goal support (GOAL; n = 214) and a combination of interventions (COMBO; n = 221).

MEASUREMENTS

Primary outcome was number of past month binge drinking days at 3-month post-randomization calculated from a 30-day time-line follow-back. Primary intention-to-treat analysis compared PLAN, USE, GOAL and COMBO against TRACK (control condition). The four active conditions were not compared against each other. A secondary outcome, durability of effects, was measured at 6 months.

FINDINGS

From baseline to 3-month follow-up (retention = 81.1%), compared with TRACK, in which past-month mean binge drinking days increased from 2.7 to 3.4, mean binge drinking days decreased in COMBO from 3.0 to 2.3 [adjusted β = -0.52; 95% confidence interval (CI) = -0.77, -0.26], GOAL from 3.0 to 2.6 (adjusted β = -0.34; 95% CI = -0.59, -0.10) and USE from 3.3 to 2.9 (adjusted β = -0.38; 95% CI = -0.62, -0.14). At 6 months (retention = 73.8%), COMBO, GOAL, USE and PLAN had significantly lower mean binge drinking days compared with TRACK.

CONCLUSION

Text message interventions incorporating feedback on either drinking plans and/or alcohol consumption and/or drinking limit goal support produced small yet durable reductions in binge drinking days in non-treatment-seeking young adults with hazardous drinking.

Assessment of substance use among injured persons seeking emergency care in Nairobi, Kenya

Introduction

Trauma is a leading cause of morbidity and mortality in Kenya. In many countries, substance use is common among patients presenting with injuries to an emergency center (EC).

Objective

To describe the epidemiology of self-reported substance use among adult injured patients seeking ED care in Nairobi, Kenya.

Methods

This prospective cross-sectional study, assessed patients presenting with injuries to the Kenyatta National Hospital ED in Nairobi, Kenya from March through June of 2021. Data on substance use, injury characteristics and ED disposition were collected. Substances of interest were alcohol, stimulants, marijuana, and opiates. The Alcohol Use Disorders Identification Test-Concise (AUDIT-C) tool was used to characterize hazardous alcohol use.

Results

A total of 1,282 patients were screened for participation, of which 646 were enrolled. Among participants, 322 (49.8%) reported substance use in the past month (AUDIT-C positive, stimulants, opiates, and/or marijuana). Hazardous alcohol use was reported by 271 (42.0%) patients who screened positive with AUDIT-C. Polysubstance use, (≥2 substances) was reported by 87 participants in the past month. Median time from injury to ED arrival was 13.1 h for all enrolees, and this number was significantly higher among substance users (median 15.4 h, IQR 5.5 - 25.5; p = 0.029).

Conclusions

In the population studied, reported substance use was common with a substantial proportion of injured persons screening positive for hazardous alcohol use. Those with substance use had later presentations for injury care. These data suggest that ED programming for substance use disorder screening and care linkage could be impactful in the study setting.

Alcohol Consumption and 15 Causes of Fatal Injuries: A Systematic Review and Meta-Analysis

INTRODUCTION

The proportion of fatal nontraffic injuries that involve high levels of alcohol use or alcohol intoxication was assessed by cause of injury to generate alcohol-attributable fractions. Updated alcohol-attributable fractions can contribute to improved estimates of the public health impact of excessive alcohol use.

METHODS

Peer-reviewed and gray literature for 1995-2019 on 15 causes of fatal nontraffic injuries in the U.S., Canada, or Mexico were systematically reviewed, and state data systems were queried for available estimates of fatalities with recorded blood alcohol concentration levels and proportions of decedents with blood alcohol concentrations ≥0.10 g/dL by cause of injury. For each injury cause, alcohol-attributable fractions across studies were synthesized by meta-analysis of single proportions using generalized linear mixed models.

RESULTS

In total, 60 published studies and 40 additional population-level data points from 6 state data systems were included. The meta-analyzed alcohol-attributable fractions by cause of injury are as follows: air-space transport (0.03), aspiration (0.24), child maltreatment (0.09), drowning (0.31), fall injuries (0.37), fire injuries (0.34), firearm injuries (0.24), homicide (0.29), hypothermia (0.29), motor vehicle nontraffic crashes (0.42), occupational and machine injuries (0.08), other road vehicle crashes (railroad trespasser injuries) (0.63), poisoning (not alcohol) (0.20), suicide (0.21), and water transport (0.27), yielding an overall median alcohol-attributable fraction of 0.27.

DISCUSSION

Excessive alcohol use is associated with substantial proportions of violent and nonviolent injury deaths. These findings can improve the data used for estimating alcohol-attributable injury deaths and inform the planning and implementation of evidence-based strategies (e.g., increasing alcohol taxes, regulating alcohol outlet density) to prevent them.

Positive associations between cannabis and alcohol use polygenic risk scores and phenotypic opioid misuse among African-Americans

BACKGROUND

This study examined whether polygenic risk scores (PRS) for lifetime cannabis and alcohol use were associated with misusing opioids, and whether sex differences existed in these relations in an urban, African-American sample.

METHODS

Data were drawn from three cohorts of participants (N = 1,103; 45% male) who were recruited in first grade as part of a series of elementary school-based, universal preventive intervention trials conducted in a Mid-Atlantic region of the U.S. In young adulthood, participants provided a DNA sample and reported on whether they had used heroin or misused prescription opioids in their lifetime. Three substance use PRS were computed based on prior GWAS: lifetime cannabis use from Pasman et al. (2018), heavy drinking indexed via maximum number of drinks from Gelernter et al. (2019), and alcohol consumption from Kranzler et al. (2019).

RESULTS

Higher PRS for lifetime cannabis use, greater heavy drinking, and greater alcohol consumption were associated with heightened risk for misusing opioids among the whole sample. Significant sex by PRS interactions were also observed such that higher PRS for heavy drinking and alcohol consumption were associated with a greater likelihood of opioid misuse among males, but not females.

CONCLUSION

Our findings further elucidate the genetic contributions to misusing opioids by showing that the genetics of cannabis and alcohol consumption are associated with lifetime opioid misuse among young adults, though replication of our findings is needed.

Alcohol use and binge drinking in baccalaureate nursing students: A descriptive study

BACKGROUND

Current literature validates that drinking is a problem on many college and university campuses. While educators are aware that drinking negatively impacts learning, it is imperative that nursing educators understand why this behavior exists and recognize strategies and opportunities to mitigate drinking for students in the nursing major.

PURPOSE

The purposes of this study were to understand the prevalence of and reasons for alcohol use and binge drinking in undergraduate baccalaureate nursing students in the United States and identify ways faculty may promote a healthy learning environment to decrease the incidence of alcohol use and binge drinking.

METHOD

This descriptive study used a web-based survey methodology. The survey contained a demographic questionnaire, alcohol use survey, and open-ended questions to address reasons for drinking and stressors. The survey was randomly distributed to baccalaureate nursing programs throughout the United States.

RESULTS

The final sample included 937 participants. Nursing students abuse alcohol for a variety of reasons including lack of understanding of binge drinking, peer pressure, dealing with mental health issues, and as a way to cope with multifaceted life stressors. Slightly over half (51%) of these participants reported drinking behavior that would be considered hazardous and 3% were in the alcohol dependent category on the alcohol use survey.

CONCLUSION

These findings are consistent with social concerns about alcohol use. Nursing students yearned for help and support from faculty regarding how to handle stress and desired faculty to be role models. Faculty who form collaborative partnerships with students, foster healthy coping strategies which may promote academic success and more importantly favorable outcomes as future practicing nurses.

Alcohol Use Cravings as a Mediator Between Associated Risk Factors on Increased Alcohol Use among Youth Adults in New York During the COVID-19 Pandemic

The sudden increase in alcohol use in the young adult population during the COVID-19 pandemic may be partially explained by social isolation and stress due to restricted stay-at-home orders. The goal of this study was to assess specific psychological factors (e.g., anxiety, depressive symptoms, sleep disturbances, and alcohol cravings) and COVID-19 diagnoses and their association with increased alcohol use and misuse during the COVID-19 pandemic among New York residents 18-35 years of age. Survey data were collected via Qualtrics between July 2020-October 2020. Path analyses tests were employed to test alcohol use cravings as a mediator. Among the total sample (N=575), mean age was 27.94±4.12; a majority were White non-Hispanic (66%), female (55%) and had completed a 4-year college or university degree (n = 249; 43.5%). Results revealed that alcohol use cravings was a significant mediator between sleep disturbances, having a COVID-19 diagnoses, and having mental health symptoms on increased alcohol use. Our findings underscore the importance of providing alcohol use prevention and treatment resources in this unprecedented COVID-19 era. Policymakers, public health professionals, and clinicians have a significant role in curbing the COVID-19-induced substance use epidemic.
