NIAAA BUDGET
 

Fiscal Year (FY) 2019

 On September 28, 2018, the President signed H.R.6157 - Department of Defense and Labor, Health and Human Services, and Education Appropriations Act, 2019 and Continuing Appropriations Act, 2019 Public Law No. 115-245. The National Institutes of Health (NIH) received a total of $39.3 billion, $2.1 billion above the fiscal year 2018 enacted level. This funding includes allocations for the HEAL Initiative, the 21st Century Cures Act, the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, and research on influenza. The bill provides a general increase to NIH Institutes and Centers and it continues to support for the Gabriella Miller Kids First Act pediatric research initiative.

 The FY 2019 appropriation for NIAAA provides $525.6 million. This represents a $16 million or a 3.1 percent increase over the FY 2018 budget level. NIAAA estimates it will support a total of 793 RPGs in FY 2019.
 

FY 2020

The President released his FY 2020 budget in March, requesting $34.4 billion for NIH, a $4.9 billion decrease from FY 2019, and $452.4 million for NIAAA, a $73.2 million decrease from FY 2019

NIAAA RESEARCH HIGHLIGHTS

 

Biomarkers of Macrophage Activation and Immune Danger Signals Predict Clinical Outcomes in Alcoholic Hepatitis

Significance: The Model for End-Stage Liver Disease (MELD) score is a combined index of lab test results for liver and renal functions and has been the gold standard for prognostic evaluation of severe liver disease conditions. However, the MELD score is a poor mortality predictor for patients with alcoholic hepatitis. This study assessed novel candidate biomolecules, focusing on a panel of recently identified potential biomarkers of tissue injury and immune cell activation. Among these, plasma levels of soluble cluster of differentiation 14 (sCD14), soluble cluster of differentiation 163 (sCD163), and osteopontin (OPN) show promise in predicting not only 90-day alcoholic hepatitis mortality, but also infection and organ failure. Prior to application of any of the potential biomarkers in clinical settings, validation in additional cohorts will be required.

Although mortality due to acute alcoholic hepatitis (AH) correlates with Model for End-Stage Liver Disease (MELD) scores, new biomarkers are critically needed to manage this disease. An increase in inflammatory markers and macrophage activation are associated with acute AH and could be potential biomarkers of clinical events and/or mortality. We enrolled 89 clinically-diagnosed AH patients in four US academic medical centers. Plasma from AH patients had a significant increase in gut microbial translocation indicators (endotoxin, bacterial 16S rDNA) and host response indicators (soluble (s)CD14 and lipopolysaccharide binding protein, LBP) compared to controls. Patient MELD and Glasgow Alcoholic Hepatitis scores (GAHS) correlated with endotoxin levels. AH patients also had a significant increase in High Mobility Group Protein 1 (HMGB1), a sterile danger signal molecule, and osteopontin (OPN), a multifunctional phosphoprotein involved in neutrophil activation, compared to controls. Increased levels of OPN positively correlated with increasing MELD scores and GAHS and LBP levels. Consistent with these results, AH patients had significantly increased circulating levels of macrophage activation (sCD163 and sCD206) markers compared to healthy controls and sCD163 and sCD206 significantly and positively correlated with OPN, HMGB1, and LBP levels as well as with MELD and GAHS scores. These findings indicate a connection between microbial translocation, immune cell activation and AH severity. Plasma sCD14, OPN, sCD163 and sCD206 levels were significantly higher in non-survivors than survivors. In multivariate regression models, we identified sCD14, sCD163, and OPN as independent predictors of 90-day mortality, infection, and organ failure development, respectively. Thus, our study suggests that sCD14, LBP, OPN, sCD163, and sCD206 are new biomarkers to indicate severity and predict clinical outcomes in AH.

 Preconception Paternal Alcohol Exposure Exerts Sex-Specific Effects on Offspring Growth and Long-Term Metabolic Programming

 Significance: Previous animal research has demonstrated that paternal chronic alcohol exposure prior to conception has developmental consequences for offspring, including sex-specific growth restriction and placental dysfunction during gestation. This study examined the long-term effects of chronic preconception paternal alcohol exposure on offspring growth and metabolic programming. Results indicated that paternal alcohol exposure is associated with prolonged fetal gestation and increased intrauterine growth restriction, which affected male offspring more than females. Male growth deficits persisted into adult life and were associated with insulin hypersensitivity, increased markers of hepatic fibrosis, and alterations in immune signaling. These abnormalities may suggest alterations in a sperm-inherited epigenetic program that influences the formation and function of the placenta. Importantly, these findings suggest that preconception lifestyle choices of biological fathers may impact offspring.

 Background: Although clinical data support an association between paternal alcohol use and deficits in child neurocognitive development, the relationship between paternal drinking and alcohol-induced growth phenotypes remains challenging to define. Using an established mouse model of chronic exposure, previous work by our group has linked preconception paternal alcohol use to sex-specific patterns of fetal growth restriction and placental dysfunction. The aim of the present study was to investigate the long-term impact of chronic preconception paternal alcohol use on offspring growth and metabolic programming. Results: Preconception paternal alcohol exposure induced a prolonged period of fetal gestation and an increased incidence of intrauterine growth restriction, which affected the male offspring to a greater extent than the females. While the female offspring of ethanol-exposed males were able to match the body weights of the controls within the first 2 weeks of postnatal life, male offspring continued to display an 11% reduction in weight at 5 weeks of age and a 6% reduction at 8 weeks of age. The observed growth deficits associated with insulin hypersensitivity in the male offspring, while in contrast, females displayed a modest lag in their glucose tolerance test. These metabolic defects were associated with an up-regulation of genes within the pro-fibrotic TGF-β signaling pathway and increased levels of cellular hydroxyproline within the livers of the male offspring. We observed suppressed cytokine profiles within the liver and pancreas of both the male and female offspring, which correlated with the up-regulation of genes in the LiverX/RetinoidX/FarnesoidX receptor pathways. However, patterns of gene expression were highly variable between the offspring of alcohol-exposed sires. In the adult offspring of alcohol-exposed males, we did not observe any differences in the allelic expression of Igf2 or any other imprinted genes. Conclusions: The impact of paternal alcohol use on child development is poorly explored and represents a significant gap in our understanding of the teratogenic effects of ethanol. Our studies implicate paternal exposure history as an additional and important modifier of alcohol-induced growth phenotypes and challenge the current maternal-centric exposure paradigm.

 Inactivation of a CRF-Dependent Amygdalofugal Pathway Reverses Addiction-Like Behaviors in Alcohol-Dependent Rats

 Significance:  Previous research has strongly implicated the central nucleus of the amygdala (CeA) in stress and alcohol withdrawal-related effects, including elevated consumption. The current study identifies a population of corticotropin-releasing factor (CRF) neurons projecting from the CeA to the bed nucleus of the stria terminalis (BNST) that are activated by withdrawal from chronic alcohol exposure in rats. Inactivation of these CRF neurons decreased the intensity of somatic withdrawal signs and attenuated the escalation of alcohol drinking. These results suggest that drugs or gene therapies targeting this neural pathway may effectively treat symptoms of AUD.

The activation of a neuronal ensemble in the central nucleus of the amygdala (CeA) during alcohol withdrawal has been hypothesized to induce high levels of alcohol drinking in dependent rats. In the present study we describe that the CeA neuronal ensemble that is activated by withdrawal from chronic alcohol exposure contains ~80% corticotropin-releasing factor (CRF) neurons and that the optogenetic inactivation of these CeA CRF+ neurons prevents recruitment of the neuronal ensemble, decreases the escalation of alcohol drinking, and decreases the intensity of somatic signs of withdrawal. Optogenetic dissection of the downstream neuronal pathways demonstrates that the reversal of addiction-like behaviors is observed after the inhibition of CeA CRF projections to the bed nucleus of the stria terminalis (BNST) and that inhibition of the CRFCeA-BNST pathway is mediated by inhibition of the CRF-CRF1 system and inhibition of BNST cell firing. These results suggest that the CRFCeA-BNST pathway could be targeted for the treatment of excessive drinking in alcohol use disorder.

 Chronic Alcohol Drinking Slows Brain Development in Adolescent and Young Adult Nonhuman Primates

 Significance:  Alcohol misuse during late adolescence and early adulthood is a risk factor for the development of alcohol use disorder. This longitudinal study used a macaque model of daily alcohol self-administration and in vivo imaging to quantify the impact of chronic alcohol exposure on neural alterations that occur during this developmental period. Heavy alcohol self-administration during late adolescence was associated with reduced growth rates of the subcortical thalamus, cerebral white matter, and overall brain volume. These results demonstrate that heavy alcohol exposure during the transition to young adulthood significantly impacts brain development in macaques, an insult that may lead to the continuation of heavy drinking throughout later adult life.

 The transition from adolescence to adulthood is associated with brain remodeling in the final stages of developmental growth. It is also a period when a large proportion of this age group engages in binge alcohol drinking (occasional consumption of four to five drinks leading to intoxication) and heavy alcohol drinking (binge drinking on 5 d in a month). Here we report on magnetic resonance imaging of developmental changes in the brain occurring during late adolescence and early adulthood (3.5–7.5 years of age) in a rhesus macaque model of alcohol self-administration. Monkeys were imaged prior to alcohol exposure, and following 6 and 12 months of daily (22 h/d) access to ethanol and water. The results revealed that the brain volume increases by 1ml/1.87 years throughout the late adolescence and early adulthood in controls. Heavy alcohol drinking reduced the rate of brain growth by 0.25 ml/year per 1 g/kg daily ethanol. Cortical volume increased throughout this period with no significant effect of alcohol drinking on the cortical growth rate. In subcortical regions, age-dependent increases in the volumes of globus pallidus, thalamus, brainstem, and cerebellum were observed. Heavy drinking attenuated the growth rate of the thalamus. Thus, developmental brain volume changes in the span of late adolescence to young adulthood in macaques is altered by excessive alcohol, an insult that may be linked to the continuation of heavy drinking throughout later adult life.

 Chronic Intermittent Ethanol Exposure Selectively Increases Synaptic Excitability in the Ventral Domain of the Rat Hippocampus 

Significance:  Evidence for distinct functional roles of hippocampal subregions suggests that the dorsal hippocampus (dHC) primarily mediates spatial learning and memory whereas the ventral hippocampus (vHC) regulates anxiety- and depressive-like behaviors. Previous research has implicated hippocampal dysregulation in the pathophysiology of alcohol use disorder (AUD), but the discrete effects of chronic alcohol on synaptic transmission in the vHC compared to the dHC have not been characterized. This study demonstrated that withdrawal from chronic intermittent alcohol exposure enhances synaptic excitability specifically in the vHC, providing insight into a neural mechanism that may contribute to the negative affect observed during abstinence in AUD.

Abstract: Many studies have implicated hippocampal dysregulation in the pathophysiology of alcohol use disorder (AUD). However, over the past twenty years, a growing body of evidence has revealed distinct functional roles of the dorsal (dHC) and ventral (vHC) hippocampal subregions, with the dHC being primarily involved in spatial learning and memory and the vHC regulating anxiety- and depressive-like behaviors. Notably, to our knowledge, no rodent studies have examined the effects of chronic ethanol exposure on synaptic transmission along the dorsal/ventral axis. To that end, we examined the effects of the chronic intermittent ethanol vapor exposure (CIE) model of AUD on dHC and vHC synaptic excitability. Adult male Long–Evans rats were exposed to CIE or AIR for 10 days (12 h/day; targeting blood ethanol levels of 175–225 mg%) and recordings were made 24 h into withdrawal. As expected, this protocol increased anxiety-like behaviors on the elevated plus-maze and successive alleys test. Extracellular recordings revealed marked CIE-associated increases in synaptic excitation in the CA1 region that were exclusively restricted to the ventral domain of the hippocampus. Western blot analysis of synaptoneurosomal fractions revealed that the expression of two proteins that regulate synaptic strength, GluA2 and SK2, were dysregulated in the vHC, but not the dHC, following CIE. Together, these findings suggest that the ventral CA1 region may be particularly sensitive to the maladaptive effects of chronic ethanol exposure and provide new insight into some of the neural substrates that may contribute to the negative affective state that develops during withdrawal.

 Endocannabinoid Control of the Insular-Bed Nucleus of the Stria Terminalis Circuit Regulates Negative Affective Behavior Associated with Alcohol Abstinence

Significance: Negative affect during alcohol abstinence is a feature of alcohol use disorder (AUD) that may promote relapse. Using a mouse model of chronic alcohol consumption followed by forced abstinence, this study demonstrates that the endocannabinoid-sensitive projection from the insular cortex to the dorsal bed nucleus of the stria terminalis (dBNST) plays a key role in regulating negative affective behavior. These results establish the insula-dBNST neurocircuit as a promising target for endocannabinoid-based pharmacotherapy to alleviate negative affective symptoms associated with abstinence in AUD.

Negative affect is a core symptom domain associated with an array of neurological and psychiatric disorders and is only partially targeted by current therapies, highlighting the need for better, more targeted treatment options. This study focuses on negative affective symptoms associated with prolonged alcohol abstinence, one of the leading causes of relapse. Using a mouse model of chronic alcohol consumption followed by forced abstinence (CDFA), prolonged alcohol abstinence increased c-fos expression and spontaneous glutamatergic neurotransmission in the dorsal bed nucleus of the stria terminalis (dBNST), a region heavily implicated in negative affect in both humans and rodents. Further, pharmacologically enhancing endogenous cannabinoids (eCB) with JZL184 prevents abstinence-induced increases in dBNST neuronal activity, underscoring the therapeutic potential of drugs targeting the brain's eCB system. Next, we used a channelrhodopsin-assisted mapping strategy to identify excitatory inputs to the dBNST that could contribute to CDFA-induced negative affect. We identified the insular cortex (insula), a region involved in regulating interoception, as a dense, functional, eCB-sensitive input to the dBNST. Using a chemogenetic strategy to locally mimic eCB signaling, we demonstrate that the insula strongly influences the CDFA behavioral phenotype and dBNST neuronal activity. Lastly, we used an anterograde strategy for transynaptic targeting of Cre expression in combination with a Gq-DREADD to selectively recruit dBNST neurons receiving insula projections. Chemogenetic recruitment of these neurons mimicked behavioral and c-fos responses observed in CDFA. Collectively, this study supports a role for the insula-BNST neural circuit in negative affective disturbances and highlights the therapeutic potential of the eCB system for treating negative affective disorders.

The lncRNA BDNF-AS is an Epigenetic Regulator in the Human Amygdala in Early Onset Alcohol Use Disorders

Significance: Long non-coding RNAs (lncRNA), which regulate gene expression and chromatin structure, play an important role in normal brain development. Brain-derived neurotropic factor (BDNF) is a critical molecular player in alcohol use disorder (AUD), and BDNF antisense (BDNF-AS) is a lncRNA that negatively regulates BDNF. The current study compared BDNF-AS expression and associated epigenetic mechanisms in the postmortem human amygdala in individuals with AUD who began drinking either before (“early onset”) or after (“late onset”) age 21 to age-matched control samples. Increased BDNF-AS expression in the amygdala was observed in the early onset AUD group, suggesting a possible role for developmentally-sensitive lncRNAs in early onset AUD. These results suggest that regulation of BDNF may prove useful in the treatment of adult psychopathology after adolescent alcohol drinking.

Objective: Previous work has found that individuals with alcohol dependence have decreased circulating BDNF in blood. Also, transgenic mice harboring a homolog of a common human polymorphism of BDNF (Val66Met) compulsively consume more alcohol than wild-type mice. However, the role of BDNF in the molecular mechanisms of AUD is unknown. Design: This study evaluated the expression and functional role of BDNF-AS in postmortem amygdala of either early onset or late onset alcoholics (individuals who began drinking before or after 21 years of age, respectively) and age-matched control subjects. ChIP assay evaluated the epigenetic modifications at several different BDNF loci. Conclusions: BDNF-AS expression is increased in early onset but not in late onset AUD amygdala and appears to be regulated epitranscriptomically via decreased N6-methyladenosine on BDNF-AS. Early onset AUD individuals show repressive chromatin remodeling at several different BDNF gene loci. Also, the early immediate gene ARC, which is a downstream target of BDNF and involved in synaptic plasticity, is decreased in the amygdala of early onset AUDs through interactions with the synaptic activity response element (SARE) in the ARC promoter. Conclusions: These findings taken together with previous studies suggest that disruptions to BDNF expression and ARC signaling are likely to increase the risk for alcohol dependence, and the risk is greater if these changes occur at a critical period of brain development, such as adolescence, due to enduring effects on epigenetic programming.

The Relationship Between Impaired Control, Impulsivity, and Alcohol Self-Administration in Nondependent Drinkers

 Significance: Loss of control over drinking and impulsivity, among other behaviors, are key features of alcohol use disorder (AUD). This study examined the relationship between impaired control over drinking and alcohol consumption and the modulation of this relationship by impulsive personality traits in drinkers without AUD. Impaired control, measured by self-report, was associated with higher alcohol self-administration in a human laboratory paradigm. Impaired control was also found to be a significant mediator of the relationship between the tendency to act rashly during positive mood states (“positive urgency”) and alcohol self-administration. These findings highlight the critical role of impaired control over drinking on alcohol consumption and subjective responses in drinkers without AUD.

Impaired control over drinking is a significant marker of alcohol use disorder (AUD), and a potential target of intervention (Heather, Tebbutt, Mattick, & Zamir, 1993; Leeman, Toll, Taylor, & Volpicelli, 2009). Impaired control may be related to, but conceptually distinct from, impulsivity (Leeman, Patock-Peckham, & Potenza, 2012; Leeman, Ralevski, et al., 2014). However, the relationship between impaired control, impulsivity, and alcohol consumption, particularly in nondependent drinkers is less clear. This study aimed to characterize these relationships using a free-access intravenous alcohol self-administration (IV-ASA) paradigm in nondependent drinkers (N = 48). Results showed individuals with higher self-reported impaired control achieved higher blood alcohol concentrations (BAC) during the IV-ASA session and reported greater hedonic subjective responses to alcohol. Higher impaired control was also associated with greater positive urgency and reward sensitivity. Moderated-mediation analysis showed that the relationship between positive urgency and peak BAC was mediated by impaired control, and partially moderated by subjective alcohol response. These findings highlight the critical role of impaired control over drinking on alcohol consumption and subjective responses in nondependent drinkers.

Predictive Validity of a 2-Question Alcohol Screen at 1-, 2-, and 3-Year Follow-Up

Significance: Previous research has established the validity of NIAAA’s two-question alcohol risk youth Screening Guide, which aids primary care providers in identifying 9- to 18-year-olds at risk for alcohol-related problems, across multiple settings and underage populations. This study, conducted across a large network of pediatric emergency departments, tests the Screening Guide for its ability to accurately assess longer-term risky drinking and alcohol use disorder (AUD) in youth. Results indicated that youth showing at least “low risk” or higher on the Screening Guide at baseline were significantly more likely to report risky drinking or meet criteria for AUD, when interviewed one, two, and three years later. The Screening Guide’s brevity; ability to detect the risk of alcohol use, alcohol use, and AUD early; and ease of use should facilitate its routine use in busy clinical practice settings.

 Background: The National Institute on Alcohol Abuse and Alcoholism (NIAAA) 2-question screen is a valid adolescent alcohol screening tool. No studies have examined if this tool predicts future alcohol problems. We conducted a study at 16 pediatric emergency departments to determine the tool's predictive validity for alcohol misuse and alcohol use disorders (AUDs). Methods: Participants (N = 4834) completed a baseline assessment battery. A subsample of participants completed the battery at 1, 2, and 3 years follow up. Results: Of the 2209 participants assigned to follow-up, 1611 (73%) completed a 1-year follow-up, 1591 (72%) completed a 2-year follow-up, and 1377 (62%) completed a 3-year follow-up. The differences in AUDs between baseline NIAAA screen nondrinkers and lower-risk drinkers were statistically significant at 1 year (P = .0002), 2 years (P <.0001), and 3 years (P = .0005), as were the differences between moderate- and highest-risk drinkers at 1 and 2 years (P < .0001 and P = .0088, respectively) but not at 3 years (P = .0758). The best combined score for sensitivity (86.2% at 1 year, 75.6% at 2 years, and 60.0% at 3 years) and specificity (78.1% at 1 year, 79.2% at 2 years, and 80.0% at 3 years) was achieved by using "lower risk" and higher as a cutoff for the prediction of a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnosis. Conclusions: The NIAAA 2-question screen can accurately characterize adolescent risk for future AUDs. Future studies are needed to determine optimaluse of the screen.

Evaluation of Drinking Risk Levels as Outcomes in Alcohol Pharmacotherapy Trials: a Secondary Analysis of 3 Randomized Clinical Trials

Significance: The US Food and Drug Administration recognizes total abstinence and no heavy drinking days as outcomes for pivotal pharmacotherapy trials for alcohol use disorder (AUD). Although both outcomes are clinically intuitive, neither considers the magnitude of reduction in drinking or the potential benefits of reductions in drinking short of total abstinence or no heavy drinking. This study conducted secondary analyses of data from three multi-site AUD pharmacotherapy trials to evaluate reduction in World Health Organization (WHO) drinking risk level as a treatment outcome. This measure captures reduction in drinking, an outcome which is more often achieved by subjects than total abstinence or no heavy drinking days. Results suggest that WHO drinking risk level reduction is equally or more sensitive to treatment compared to total abstinence and no heavy drinking days, demonstrating that this measure is an indicator of treatment efficacy that could be included as an additional outcome for AUD pharmacotherapy trials.

Objective: To compare 2 drinking reduction outcomes with total abstinence and no heavy drinking outcomes. Design, Setting, and Participants: Data were obtained from 3 multisite, randomized, placebo-controlled clinical trials of medications for treating alcohol dependence (naltrexone, varenicline, and topiramate) in adults with DSM-IV-categorized alcohol dependence. Main Outcomes and Measures: Within each trial, the percentage of participants in active and placebo conditions who met responder definitions of abstinence, no heavy drinking days, a WHO 1-level reduction, and a WHO 2-level reduction was computed by month with corresponding effect sizes (Cohen h).Results: Across the 3 trials (N = 1169; mean [SD] age, 45 [10] years; 824 [70.5%] men), the percentage of participants classified as responders during the last 4 weeks of treatment was lowest for abstinence (naltrexone, 34.7% [100 of 288]; varenicline, 7.3% [7 of 96]; topiramate, 11.7% [21 of 179]) followed by no heavy drinking days (naltrexone, 51.0% [147 of 288]; varenicline, 24.0% [23 of 96]; topiramate, 20.7% [37 of 179]), WHO 2-level reduction (naltrexone, 75.0% [216 of 288]; varenicline, 55.2% [53 of 96]; topiramate, 44.7% [80 of 179]), and WHO 1-level reduction (naltrexone, 83.3% [240 of 288]; varenicline, 69.8 [67 of 96]; topiramate, 54.7% [98 of 179]) outcomes. Standardized treatment effects observed for the WHO 2-level reduction outcomes (naltrexone, Cohen h = 0.214 [95% CI, 0.053 -0.375]; varenicline, 0.273 [95% CI, -0.006 to 0.553]; topiramate, 0.230 [95% CI, 0.024-0.435]) and WHO 1-level reduction (naltrexone, Cohen h = 0.116 [95% CI, -0.046 to 0.277]; varenicline, 0.338 [95% CI, 0.058-0.617]; topiramate, 0.014 [95% CI, -0.192 to 0.219]) were comparable with those obtained using abstinence (naltrexone, Cohen h = 0.142 [95% CI, -0.020 to 0.303]; varenicline, 0.146 [95% CI, -0.133 to 0.426]; topiramate, 0.369 [95% CI, 0.163-0.574]) and no heavy drinking days (naltrexone, Cohen h = 0.140 [95% CI, -0.021 to 0.302]; varenicline, 0.232 [95% CI, -0.048 to 0.511]; topiramate, 0.207 [95% CI, 0.002-0.413]).Conclusions and Relevance: WHO drinking risk level reductions appear to be worthwhile indicators of treatment outcome in AUD pharmacotherapy trials. These outcomes may align with drinking reduction goals of many patients and capture clinically meaningful improvements experienced by more patients than either abstinence or no heavy drinking days.

DSM-5 Alcohol Use Disorder Severity as a Function of Sexual Orientation Discrimination: A National Study

Significance:  The Institute of Medicine’s 2011 report on the health of sexual and gender minorities emphasized that the absence of explanatory frameworks hampers the ability to effectively prevent, mitigate, or treat alcohol use disorder (AUD) in high‐risk vulnerable populations. This study examined the association between DSM‐5 AUD severity and sexual orientation discrimination using a nationally representative sample. Sexual minorities who experienced higher levels of sexual orientation discrimination had significantly higher levels of AUD severity than sexual minorities who experienced lower levels or no discrimination, with proximal experiences of discrimination more salient than distal experiences. These findings provide new evidence that sexual minorities who experience high levels of sexual orientation discrimination are at substantially increased risk of severe AUD.

Background: Sexual minorities are more likely than their heterosexual counterparts to develop alcohol use disorder (AUD), and understanding the underlying reasons for this heightened risk is a public health priority. This study examined relationships between sexual orientation discrimination and DSM-5 AUD severity. Methods: The 2012 to 2013 National Epidemiologic Survey on Alcohol and Related Conditions III conducted in-person interviews with a nationally representative sample of U.S. adults (N = 36,309). Approximately 2.8% of the target population self-identified as lesbian, gay, or bisexual, 3.1% had at least 1 past-year same-sex sexual partner, and 8.3% reported same-sex sexual attraction. Results: Adults who identified as lesbian, gay, bisexual, heterosexual with same-sex attraction and/or current same-sex sexual partners, and those not sure of their sexual identity, had higher rates of individual DSM-5 AUD criteria than heterosexual-identified adults with only opposite-sex attraction and sexual partners. Respondents who were bisexual or unsure of their sexual identity consistently had the highest probabilities of endorsing each of these AUD criteria relative to the other subgroups. Differences in AUD severity across sexual orientation subgroups were much larger among women than among men. Sexual minorities who experienced higher levels of sexual orientation discrimination had significantly higher levels of AUD severity than sexual minorities who experienced lower levels or no discrimination. In particular, greater levels of sexual orientation discrimination increased the odds of impaired control criteria and pharmacologic criteria. Associations between prior-to-past-year sexual orientation discrimination and AUD severity were not as robust as those involving past-year discrimination. Conclusions: Sexual minorities are at substantially greater risk of severe DSM-5 AUD, and this is particularly true among those who experience high levels of sexual orientation discrimination. Findings indicate that proximal experiences of discrimination are more salient than distal experiences. AUD treatment should address recent sexual orientation discrimination given that such experiences are associated with more severe AUD. (McCabe SEHughes TLWest BTVeliz P, and Boyd CJ.
