Strong and weak cross-inheritance of substance use disorders in a nationally representative sample.

Substance use disorders (SUDs) are moderately to highly heritable and are in part cross-transmitted genetically, as observed in twin and family studies. We performed exome-focused genotyping to examine the cross-transmission of four SUDs: alcohol use disorder (AUD, n = 4487); nicotine use disorder (NUD, n = 4394); cannabis use disorder (CUD, n = 954); and nonmedical prescription opioid use disorder (NMPOUD, n = 346) within a large nationally representative sample (n = 36,309), the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III). All diagnoses were based on in-person structured psychiatric interview (AUDADIS-5). SUD cases were compared alone and together to 3959 "super controls" who had neither a SUD nor a psychiatric disorder using an exome-focused array assaying 363,496 SNPs, yielding a representative view of within-disorder and cross-disorder genetic influences on SUDs. The 29 top susceptibility genes for one or more SUDs overlapped highly with genes previously implicated by GWAS of SUD. Polygenic scores (PGS) were computed within the European ancestry (EA) component of the sample (n = 12,505) using summary statistics from each of four clinically distinct SUDs compared to the 3959 "super controls" but then used for two distinctly different purposes: to predict SUD severity (mild, moderate, or severe) and to predict each of the other 3 SUDs. Our findings based on PGS highlight shared and unshared genetic contributions to the pathogenesis of SUDs, confirming the strong cross-inheritance of AUD and NUD as well as the distinctiveness of inheritance of opioid use disorder.

Armed Conflict, Substance Use and HIV: A Global Analysis.

Armed conflict is frequently assumed to be a contributor to the global HIV epidemic, but existing evidence is sparse. We examined the relationship between armed conflict between 2002 and 2008 and HIV disability life years (DALYs) in 2010 among WHO Member States. Using partial least squares analysis we also examined moderation of the armed conflict-HIV link by two susceptibility constructs (background risk, substance use) and one vulnerability mediator (numbers of refugees, people on ART, and total HIV spending). Background risk directly impacted HIV DALYs (p < 0.05), substance use moderated the conflict-HIV relationship (p < 0.01). The vulnerability construct mediated the conflict-HIV association (p < 0.01). Findings underscore the need to align HIV prevention/intervention efforts with pre-existing HIV burden and reduce the impact of natural disasters on the populace in conflict-affected states. Integration of substance prevention/harm reduction programs within national HIV responses, attention to most-at-risk populations and increased surveillance/treatment of drug resistant HIV and TB is warranted.

Effects of State-Level Tobacco Environment on Cigarette Smoking are Stronger Among Those With Individual-Level Risk Factors.

INTRODUCTION: To better understand the impact of the state-level tobacco environment (eg, tobacco control policies, attitudes towards smoking) on cigarette smoking, we examined whether the relationship of state tobacco environments to smoking is modified by individual-level vulnerability factors. METHODS: In a nationally representative sample of US adults (N = 34 638), past-year smoking and heavy smoking were examined. State-level tobacco environment was defined by tobacco-related control policies and attitudes, ranging from permissive to restrictive; individual vulnerability was defined by childhood maltreatment and/or parental substance problems. Additive interaction tested differences in state-level tobacco environment effects on smoking and heavy smoking by individual-level vulnerability. RESULTS: Significant interactions (P values < .01) indicated that the state tobacco environment had the strongest relationship to smoking outcomes among individuals with greatest individual vulnerability. For example, among respondents with childhood maltreatment and parental substance problems, those in states with permissive tobacco environments had 13.3% greater prevalence of smoking than those in restrictive states. Among respondents with neither individual-level risk factor, those in permissive states had 2.8% greater prevalence than those in restrictive states (interaction P value = .0002). CONCLUSIONS: Further restricting states' smoking environments could help reduce the prevalence of smoking and heavy smoking, particularly among those at increased individual risk in the general population. IMPLICATIONS: This study shows that the protective effect of restrictive state-level tobacco environments on smoking or heavy smoking was stronger among those especially vulnerable due to individual-level risk factors (parental substance problems, childhood maltreatment). Thus, public health campaigns to influence attitudes towards smoking or legislation to strengthen tobacco control could have a broad effect, particularly impacting those with vulnerability to smoking, which may help decrease smoking prevalence and reduce the massive public health burden of tobacco-related morbidity and mortality.

The epidemiology of DSM-5 posttraumatic stress disorder in the United States: results from the National Epidemiologic Survey on Alcohol and Related Conditions-III.

OBJECTIVES: To present current, nationally representative US findings on the past-year and lifetime prevalences, sociodemographic correlates, psychiatric comorbidity, associated disability, and treatment of DSM-5 posttraumatic stress disorder (PTSD). METHODS: Face-to-face interviews with 36,309 adults in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III. PTSD, alcohol and drug use disorders, and selected mood, anxiety, and personality disorders were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-5. RESULTS: Past-year and lifetime prevalences were 4.7 and 6.1 %, higher for female, white, Native American, younger, and previously married respondents, those with

Regularly Drinking Alcohol Before Sexual Activity in a Nationally Representative Sample: Prevalence, Sociodemographics, and Associations With Psychiatric and Substance Use Disorders.

OBJECTIVES: We addressed regular drinking before sex and its associated risk factors. METHODS: From the wave 2 National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative adult US sample (fielded 2004-2005), we determined the 12-month prevalence of regularly drinking alcohol before sexual activity. Among 17,491 sexually active drinkers, we determined the sociodemographic, psychiatric, and substance use correlates of regularly drinking before sex. RESULTS: Regular presex drinking's 12-month prevalence was 1.8%. Significant bivariate sociodemographic correlates were age, gender, race/ethnicity, education, family income, marital status, and employment status. Generalized anxiety disorder and alcohol dependence were associated with significantly increased odds of being a regular presex drinker after controlling for covariates. CONCLUSIONS: We estimate that 4.3 million American adults are regular presex drinkers. Future research should examine this public health issue at the population level, with particular focus on pathways that link it to psychopathology.

ADHD and the externalizing spectrum: direct comparison of categorical, continuous, and hybrid models of liability in a nationally representative sample.

PURPOSE: Alcohol use disorders, substance use disorders, and antisocial personality disorder share a common externalizing liability, which may also include attention-deficit hyperactivity disorder (ADHD). However, few studies have compared formal quantitative models of externalizing liability, with the aim of delineating the categorical and/or continuous nature of this liability in the community. This study compares categorical, continuous, and hybrid models of externalizing liability. METHOD: Data were derived from the 2004-2005 National Epidemiologic Survey on Alcohol and Related Conditions (N = 34,653). Seven disorders were modeled: childhood ADHD and lifetime diagnoses of antisocial personality disorder (ASPD), nicotine dependence, alcohol dependence, marijuana dependence, cocaine dependence, and other substance dependence. RESULTS: The continuous latent trait model provided the best fit to the data. Measurement invariance analyses supported the fit of the model across genders, with females displaying a significantly lower probability of experiencing externalizing disorders. Cocaine dependence, marijuana dependence, other substance dependence, alcohol dependence, ASPD, nicotine dependence, and ADHD provided the greatest information, respectively, about the underlying externalizing continuum. CONCLUSIONS: Liability to externalizing disorders is continuous and dimensional in severity. The findings have important implications for the organizational structure of externalizing psychopathology in psychiatric nomenclatures.

Exploring patterns of alcohol use and alcohol use disorder among Asian Americans with a finer lens.

BACKGROUND: National survey data suggest Asian Americans (AA) are less likely to consume alcohol and develop AUD than Americans in other groups. However, it is common for AA to be born outside of the US and carry gene variants that alter alcohol metabolism, both of which can lead to lower levels of alcohol involvement. The current study examined differences in alcohol use and AUD between AA and other groups before and after controlling for birth location and gene variants. DESIGN: Past year alcohol measures were examined from adults 18+ (N=22,848) in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions III before and after controlling for birth location (inside or outside of the US) and gene variants (ALDH2*2 and ADH1B*2/ADH1B*3). Gender gaps in alcohol measures also were assessed. RESULTS: Before adjustments, AA were less likely than White Americans to drink in the previous year (OR=0.50, 95% CI 0.41-0.62), binge (OR=0.68, 95% CI 0.52-0.88), engage in frequent heavy drinking (OR=0.55, 95% CI 0.42-0.73), and reach criteria for AUD (OR=0.71, 95% CI 0.53-0.94). After controlling for birth location and gene variants, AA remained less likely to drink in the past year (OR=0.54, 95% CI 0.41-0.70) but all other differences disappeared. Gender gaps were only observed for AA born outside of the US, highlighting the importance of experience rather than racial category per se. CONCLUSIONS: Findings indicate that heterogeneity among AA leads to spurious generalizations regarding alcohol use and AUD and challenge the model minority myth.

The performance of DSM-5 alcohol use disorder and quantity-frequency of alcohol consumption criteria: An item response theory analysis.

BACKGROUND: Maladaptive patterns of drinking are central to the development of AUD. However, no DSM-5 criteria ask about patterns of alcohol use, such as 5+/4+ binge drinking. It is important to examine whether such an item would improve the diagnostic utility of the DSM-5 instrument. METHOD: Using a large representative sample of the US population, we used item response theory (IRT) methodology to examine the threshold, discrimination, and information value and differential criterion functioning of DSM-5 AUD criteria, along with a 5+/4+ drinking pattern criterion assessed at various levels of frequency. RESULTS: The best fit drinking pattern criterion (defined at 5+/4+ drinking at least once a week in the past year) tapped the milder end of that continuum, which was similar to the criterion of drinking in larger amounts or for longer than intended. The new DSM-5 craving criterion was associated with mid-level values of threshold and discrimination. The AUD criteria with the addition of the 5+/4+ drinking pattern criterion demonstrated invariance across important subgroups of the population. CONCLUSIONS: Among the criteria with the lowest level of threshold, the drinking pattern criterion has demonstrated its utility of the DSM-5 classification by identifying clinically significant but milder AUD cases. Along with its relationship to AUD relapse, the new craving criterion tapped the moderate levels of threshold and discrimination and thus, argues for its continued inclusion in the DSM-5 AUD formulation. Study results showed that DSM-5 AUD criteria and the 5+/4+ drinking pattern criterion formed a unidimensional continuum of AUD severity.

Prevalence, correlates, disability, and comorbidity of DSM-IV schizotypal personality disorder: results from the wave 2 national epidemiologic survey on alcohol and related conditions.

OBJECTIVE: To present nationally representative findings on the prevalence, correlates, and comorbidity of and disability associated with DSM-IV schizotypal personality disorder (SPD). METHOD: This study used the 2004-2005 Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions, which targeted a nationally representative sample of the adult civilian population of the United States aged 18 years and older and residing in households and group quarters. In Wave 2, attempts were made to conduct face-to-face reinterviews with all respondents to the Wave 1 interview. RESULTS: Lifetime prevalence of SPD was 3.9%, with significantly greater rates among men (4.2%) than women (3.7%) (p < .01). Odds for SPD were significantly greater among black women, individuals with lower incomes, and those who were separated, divorced, or widowed; odds were significantly lower among Asian men (all p < .01). Schizotypal personality disorder was associated with substantial mental disability in both sexes. Co-occurrence rates of Axis I and other Axis II disorders among respondents with SPD were much higher than rates of co-occurrence of SPD among respondents with other disorders. After adjustment for sociodemographic characteristics and additional comorbidity, associations remained significant in both sexes between SPD and 12-month and lifetime bipolar I disorder, social and specific phobias, and posttraumatic stress disorder, as well as 12-month bipolar II disorder, lifetime generalized anxiety disorder, and borderline and narcissistic personality disorders (all p < .01). CONCLUSIONS: Common and unique factors may underlie associations of SPD with narcissistic and borderline personality disorders, whereas much of the comorbidity between SPD and most mood and anxiety disorders appears to reflect factors common to these disorders. Some of the associations with SPD were sex specific. Schizotypal personality disorder and dependent, avoidant, and borderline personality disorders were associated with the occurrence of schizophrenia or psychotic episode. Schizotypal personality disorder is a prevalent, fairly stable, highly disabling disorder in the general population. Sex differences in associations of SPD with other specific Axis I and II disorders can inform more focused, hypothesis-driven investigations of factors underlying the comorbid relationships. Schizotypal as well as borderline, dependent, and avoidant personality disorders may be components of the schizophrenia spectrum.

Changes in the prevalence and correlates of cocaine use and cocaine use disorder in the United States, 2001-2002 and 2012-2013.

To present nationally representative data on changes in the prevalences of 12-month cocaine use, cocaine use disorder (CocUD) and 12-month CocUD among 12-month cocaine users between 2001 and 2002 and 2012-2013. Data were derived from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and the 2012-2013 NESARC-III. Between 2001 and 2002 and 2012-2013, prevalences of 12-month cocaine use and DSM-IV CocUD significantly increased and 12-month CocUD among 12-month users significantly decreased. Increases in risk of cocaine use were seen across nearly all sociodemographic subgroups while increases in CocUD were observed among women, those in the oldest age group, Whites, individuals with the lowest incomes and highest education, and those residing in urban areas. Prevalence of CocUD among users significantly declined overall and among men, individuals aged 30-44 years old, the never-married, respondents with incomes between $20,000 and $34,000, and those residing in the Midwest. Increases in coca cultivation in Colombia in recent years together with increases in the purity of cocaine entering the U.S. portend more significant increases in the rates of cocaine use and CocUD in the U.S. along with increases in cocaine-related morbidity and mortality. The results of this study support the continued monitoring of cocaine use and CocUD in the U.S., especially in view of the narrowing of the gender gap and shifts in race-ethnic, age and socioeconomic differentials seen between 2001 and 2002 and 2012-2013.

The alcohol use disorder and associated disabilities interview schedule-IV (AUDADIS-IV): reliability of new psychiatric diagnostic modules and risk factors in a general population sample.

This study presents test-retest reliability statistics and information on internal consistency for new diagnostic modules and risk factors for alcohol, drug, and psychiatric disorders from the Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV (AUDADIS-IV). Test-retest statistics were derived from a random sample of 1899 adults selected from 34,653 respondents who participated in the 2004-2005 Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Internal consistency of continuous scales was assessed using the entire Wave 2 NESARC. Both test and retest interviews were conducted face-to-face. Test-retest and internal consistency results for diagnoses and symptom scales associated with posttraumatic stress disorder, attention-deficit/hyperactivity disorder, and borderline, narcissistic, and schizotypal personality disorders were predominantly good (kappa>0.63; ICC>0.69; alpha>0.75) and reliability for risk factor measures fell within the good to excellent range (intraclass correlations=0.50-0.94; alpha=0.64-0.90). The high degree of reliability found in this study suggests that new AUDADIS-IV diagnostic measures can be useful tools in research settings. The availability of highly reliable measures of risk factors for alcohol, drug, and psychiatric disorders will contribute to the validity of conclusions drawn from future research in the domains of substance use disorder and psychiatric epidemiology.

DSM-5 cannabis use disorder in the National Epidemiologic Survey on Alcohol and Related Conditions-III: Gender-specific profiles.

OBJECTIVE: The objective of this study was to present current information on the prevalence, correlates, comorbidity and quality of life among men and women with cannabis use disorder (CUD). METHODS: In 2012-2013, 36,309 respondents ≥18years old participated in face-to-face interviews in the National Epidemiologic Survey on Alcohol and Related Conditions-III. RESULTS: Prevalence of 12-month CUD was greater among men (3.5%) than women (1.7%). Women experienced shorter duration from onset of cannabis use to onset of CUD than men (mean=5.8years, men; mean=4.7years, women). In both men and women, prevalences of CUD were greater among young adults, Blacks, and those with lower income and greater among Native American women relative to White women. CUD was highly comorbid with other substance use disorders, PTSD, ASPD and borderline and schizotypal PDs for men and women. Quality of life for individuals with CUD was low regardless of gender. CONCLUSIONS: DSM-5 CUD among men and women is highly prevalent, comorbid and characterized by low quality of life. Results highlighted the need for integrated treatment of CUD and comorbid disorders and the urgency of identifying and implementing effective prevention and intervention approaches, especially for those sociodemographic subgroups for which both men and women are at greater risk for the disorder.

Concurrent use of alcohol with other drugs and DSM-5 alcohol use disorder comorbid with other drug use disorders: Sociodemographic characteristics, severity, and psychopathology.

BACKGROUND: Little is known about the sociodemographic profiles, the intensity of drinking, the severity of alcohol use disorder (AUD), and psychopathology among individuals with specific patterns of concurrent alcohol and drug use and AUD and other drug use disorders (DUDs) comorbidity. METHODS: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions-III. We examined sociodemographic correlates and psychopathology among individuals with specific patterns of concurrent use of alcohol and drug and AUD-DUD comorbidity relative to alcohol use or AUD only, respectively, using multinomial logistic regression. We also examined whether concurrent alcohol and drug use and AUD-DUD comorbidity increased the intensity of drinking and severity of AUD, respectively. RESULTS: The majority (62.0%) of past-year drinkers used only alcohol. The 12-month prevalence of AUD only was 53.5%. Individuals with concurrent use of alcohol and drugs and AUD-DUD comorbidity were more likely to be men, younger, never/previously married, with lower education and income (odds ratios (ORs) ≥ 1.2). Concurrent use of alcohol and drugs and AUD- DUD comorbidity groups were more likely to experience psychopathology than the alcohol use only and AUD only groups, respectively (ORs ≥ 1.3). The intensity of drinking was greater among the concurrent use groups relative to the alcohol use only group, while the severity of AUD was greater among AUD-DUD comorbidity groups relative to the AUD only group. CONCLUSIONS: Research on consequences and treatment outcome of concurrent use of alcohol and drugs and AUD-DUD comorbidity is warranted to inform the development of more effective prevention/intervention programs.

Epidemiology of Adult DSM-5 Major Depressive Disorder and Its Specifiers in the United States.

Importance: No US national data are available on the prevalence and correlates of DSM-5-defined major depressive disorder (MDD) or on MDD specifiers as defined in DSM-5. Objective: To present current nationally representative findings on the prevalence, correlates, psychiatric comorbidity, functioning, and treatment of DSM-5 MDD and initial information on the prevalence, severity, and treatment of DSM-5 MDD severity, anxious/distressed specifier, and mixed-features specifier, as well as cases that would have been characterized as bereavement in DSM-IV. Design, Setting, and Participants: In-person interviews with a representative sample of US noninstitutionalized civilian adults (≥18 years) (n = 36 309) who participated in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions III (NESARC-III). Data were collected from April 2012 to June 2013 and were analyzed in 2016-2017. Main Outcomes and Measures: Prevalence of DSM-5 MDD and the DSM-5 specifiers. Odds ratios (ORs), adjusted ORs (aORs), and 95% CIs indicated associations with demographic characteristics and other psychiatric disorders. Results: Of the 36 309 adult participants in NESARC-III, 12-month and lifetime prevalences of MDD were 10.4% and 20.6%, respectively. Odds of 12-month MDD were significantly lower in men (OR, 0.5; 95% CI, 0.46-0.55) and in African American (OR, 0.6; 95% CI, 0.54-0.68), Asian/Pacific Islander (OR, 0.6; 95% CI, 0.45-0.67), and Hispanic (OR, 0.7; 95% CI, 0.62-0.78) adults than in white adults and were higher in younger adults (age range, 18-29 years; OR, 3.0; 95% CI, 2.48-3.55) and those with low incomes ($19 999 or less; OR, 1.7; 95% CI, 1.49-2.04). Associations of MDD with psychiatric disorders ranged from an aOR of 2.1 (95% CI, 1.84-2.35) for specific phobia to an aOR of 5.7 (95% CI, 4.98-6.50) for generalized anxiety disorder. Associations of MDD with substance use disorders ranged from an aOR of 1.8 (95% CI, 1.63-2.01) for alcohol to an aOR of 3.0 (95% CI, 2.57-3.55) for any drug. Most lifetime MDD cases were moderate (39.7%) or severe (49.5%). Almost 70% with lifetime MDD had some type of treatment. Functioning among those with severe MDD was approximately 1 SD below the national mean. Among 12.9% of those with lifetime MDD, all episodes occurred just after the death of someone close and lasted less than 2 months. The anxious/distressed specifier characterized 74.6% of MDD cases, and the mixed-features specifier characterized 15.5%. Controlling for severity, both specifiers were associated with early onset, poor course and functioning, and suicidality. Conclusions and Relevance: Among US adults, DSM-5 MDD is highly prevalent, comorbid, and disabling. While most cases received some treatment, a substantial minority did not. Much remains to be learned about the DSM-5 MDD specifiers in the general population.

The role of alcohol consumption in future classifications of alcohol use disorders.

BACKGROUND: Item response theory (IRT) was used to determine whether DSM-IV alcohol abuse and dependence and consumption criteria were arrayed along a continuum of severity. METHODS: Data came from a large, nationally representative sample of the U.S. adult population. RESULTS: DSM-IV alcohol abuse and dependence criteria formed a continuum of alcohol use disorder severity along with the drinking 5+/4+ at least once a week in the past year criterion. Criteria were invariant across sex, race-ethnicity, and age subgroups. CONCLUSION: The drinking 5+/4+ high-risk drinking pattern was identified as a suitable criterion for future classifications of DSM-IV alcohol use disorder. Some dependence criteria were among the least severe criteria, and some abuse criteria were among the most severe, findings that question the validity of DSM-IV abuse and dependence categories as distinct entities and that do not support the assumption of abuse as prodromal to dependence. Physical dependence and addiction were identified as defining elements of the continuum. Further research examining their dimensional properties and relationships to high-risk drinking patterns appears warranted. An approach highlighting a more important role of consumption in future classifications of alcohol use disorder defined broadly to encompass all alcohol-related harm, including addiction and physical dependence, is discussed.

National Trends in Suicide Attempts Among Adults in the United States.

Importance: A recent increase in suicide in the United States has raised public and clinical interest in determining whether a coincident national increase in suicide attempts has occurred and in characterizing trends in suicide attempts among sociodemographic and clinical groups. Objective: To describe trends in recent suicide attempts in the United States. Design, Setting, and Participants: Data came from the 2004-2005 wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and the 2012-2013 NESARC-III. These nationally representative surveys asked identical questions to 69 341 adults, 21 years and older, concerning the occurrence and timing of suicide attempts. Risk differences adjusted for age, sex, and race/ethnicity (ARDs) assessed trends from the 2004-2005 to 2012-2013 surveys in suicide attempts across sociodemographic and psychiatric disorder strata. Additive interactions tests compared the magnitude of trends in prevalence of suicide attempts across levels of sociodemographic and psychiatric disorder groups. The analyses were performed from February 8, 2017, through May 31, 2017. Main Outcomes and Measures: Self-reported attempted suicide in the 3 years before the interview. Results: With use of data from the 69 341 participants (42.8% men and 57.2% women; mean [SD] age, 48.1 [17.2] years), the weighted percentage of US adults making a recent suicide attempt increased from 0.62% in 2004-2005 (221 of 34 629) to 0.79% in 2012-2013 (305 of 34 712; ARD, 0.17%; 95% CI, 0.01%-0.33%; P = .04). In both surveys, most adults with recent suicide attempts were female (2004-2005, 60.17%; 2012-2013, 60.94%) and younger than 50 years (2004-2005, 84.75%; 2012-2013, 80.38%). The ARD for suicide attempts was significantly larger among adults aged 21 to 34 years (0.48%; 95% CI, 0.09% to 0.87%) than among adults 65 years and older (0.06%; 95% CI, -0.02% to 0.14%; interaction P = .04). The ARD for suicide attempts was also significantly larger among adults with no more than a high school education (0.49%; 95% CI, 0.18% to 0.80%) than among college graduates (0.03%; 95% CI, -0.17% to 0.23%; interaction P = .003); the ARD was also significantly larger among adults with antisocial personality disorder (2.16% [95% CI, 0.61% to 3.71%] vs 0.07% [95% CI, -0.09% to 0.23%]; interaction P = .01), a history of violent behavior (1.04% [95% CI, 0.35% to 1.73%] vs 0.00% [95% CI, -0.12% to 0.12%]; interaction P = .003), or a history of anxiety (1.43% [95% CI, 0.47% to 2.39%] vs 0.18% [95% CI, 0.04% to 0.32%]; interaction P = .01) or depressive (0.99% [95% CI, -0.09% to 2.07%] vs -0.08% [95% CI, -0.20% to 0.04%]; interaction P = .05) disorders than among adults without these conditions. Conclusions and Relevance: A recent overall increase in suicide attempts among adults in the United States has disproportionately affected younger adults with less formal education and those with antisocial personality disorder, anxiety disorders, depressive disorders, and a history of violence.

Predictors of treatment utilization and barriers to treatment utilization among individuals with lifetime cannabis use disorder in the United States.

OBJECTIVE: To present information on predictors of treatment utilization and barriers to treatment utilization among individuals with lifetime DSM-5 cannabis use disorder (CUD). METHOD: Face-to-face survey of a representative sample of the adult US general population (n=36,309). RESULTS: Treatment rates for CUD were low in this general population survey (13.7%). Severity of CUD and comorbidity of other lifetime drug use disorders were significant predictors of lifetime treatment utilization for CUD. Preference for self-reliance, minimizing problems, fear of stigma, and financial and structural issues were among the most frequently endorsed reasons for respondents not seeking treatment when they perceived the need for treatment among individuals with lifetime CUD, regardless of whether they eventually utilized treatment at some time in their lives. CONCLUSIONS: Given the rising prevalence of CUD in the US over the past decade and currently low treatment rates for CUD, increased provision for services for CUD appears critically needed, especially those that screen for and treat, when present, other drug use disorders. Programs to reduce stigma and financial barriers are needed, as well as programs to increase awareness among the general public, health care professionals about the nature and seriousness of CUD, and the availability and effectiveness of treatment for this disorder.

Prevalence, correlates, comorbidity and treatment of electronic nicotine delivery system use in the United States.

INTRODUCTION: This study presents nationally representative data on the prevalence, correlates, psychiatric comorbidity and treatment (including pharmacological and nonpharmacological) among electronic nicotine delivery system (ENDS) users. METHODS: Face-to-face interviews in the National Epidemiologic Survey on Alcohol and Related Conditions-III. RESULTS: Prevalences of 12-month and lifetime ENDS use were 3.8% (SE=0.14) and 5.4% (SE=0.17). Odds of ENDS use were greater among men than women, regardless of timeframe. Rates were lower among Blacks, Hispanics and Asians/Pacific Islanders relative to Whites. Odds of 12-month and lifetime ENDS use was also higher among younger (<65years) than older (≥65years) individuals and higher among individuals with high school education relative to these with some college education. Odds of 12-month and lifetime ENDS use was also higher among individuals with incomes <$70,000.00 compared with those with incomes≥$70,000.00 and higher among the previously married relative to those who were currently married. Associations between 12-month ENDS use and severe nicotine use disorder were strong, whereas associations with other substance use disorders and borderline and antisocial personality disorders were modest (AORs=1.3-2.6). Rates of treatment seeking to cut down or quit tobacco or nicotine use (12-month, 25.0% (SE=1.6); lifetime, 24.4% (SE=1.4)) were low. CONCLUSIONS: ENDS use is substantially comorbid, especially with nicotine use disorder. Virtually all ENDS users smoked cigarettes. Research is needed to understand their role in smoking cessation, adverse effects on bodily systems and their potential for addiction and comorbidity.

The Epidemiology of Antisocial Behavioral Syndromes in Adulthood: Results From the National Epidemiologic Survey on Alcohol and Related Conditions-III.

OBJECTIVE: To present current, nationally representative US findings on prevalence, correlates, psychiatric comorbidity, disability, and treatment of DSM-5 antisocial personality disorder (ASPD) and adulthood antisocial behavioral syndrome without conduct disorder before 15 years of age (AABS). METHOD: Face-to-face interviews were conducted with respondents (N = 36,309) in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III. DSM-5 alcohol, nicotine, and specific drug use disorders and selected mood, anxiety, trauma-related, eating, and personality disorders were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-5. RESULTS: Prevalences of ASPD and AABS were 4.3% and 20.3%, respectively, and were highest among male, white, Native American, younger, and unmarried respondents, those with high school or less education, lower incomes, and Western residence. Both antisocial syndromes were significantly associated with 12-month and lifetime substance use, dysthymia/persistent depressive, bipolar I, posttraumatic stress, and borderline and schizotypal personality disorders (odds ratios [ORs] = 1.2-7.0). ASPD was additionally associated with 12-month agoraphobia and lifetime generalized anxiety disorder (ORs = 1.3-1.6); AABS, with 12-month and lifetime major depressive and 12-month generalized anxiety disorders (ORs = 1.2-1.3). Both were associated with significant disability (P < .001 to .01). Most antisocial survey respondents were untreated. CONCLUSIONS: One in 4 US adults exhibits syndromal antisocial behavior, with similar sociodemographic and psychiatric correlates and disability regardless of whether onset occurred before 15 years of age, illustrating the clinical and public health significance of both ASPD and AABS. In addition to laying groundwork for estimates of social and economic costs, and further etiologic and nosologic research, these findings highlight the urgency of effectively preventing and treating antisocial syndromes, including investigation of whether treatment for comorbidity hastens symptomatic remission and improves quality-of-life outcomes.

Prevalence, sociodemographic correlates and DSM-5 substance use disorders and other psychiatric disorders among sexual minorities in the United States.

PURPOSE: The purpose of this study was to present current nationally representative data on the prevalences, sociodemographic correlates and risk of DSM-5 substance use disorders and other psychiatric disorders among sexual minorities (SMs) relative to heterosexuals, and among SMs by gender. METHODS: Data were derived from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III. RESULTS: In the general noninstitutionalized population, 1.5%, 1.3% and 0.5% of individuals self-identified as gay/lesbian, bisexual and not sure sexual orientations. Men were more likely to report gay/lesbian orientation than women (1.8% vs. 1.2%). Women were more likely than men to report bisexual (1.8% vs. 0.8%) and not sure (0.6% vs. 0.4%) sexual orientations. Sociodemographic characteristics varied across sexual orientation and gender. Relative to heterosexuals, disparities in substance use and psychiatric disorders were found across sexual orientations, especially among bisexual women. Greater rates of specific psychiatric disorders were also demonstrated by women reporting bisexual and not sure orientations relative to lesbian women, with fewer differences in rates of psychopathology among SM men. CONCLUSIONS: Despite growing acceptance of SMs and SM rights over the past decade, substantial mental health disparities exist among these subgroups of the U.S. noninstitutionalized population, especially among bisexual women. More research is needed to understand these mental health disparities, while considering nuances of multiple intersecting minority identities and unique contextual factors. FINDINGS: underscore the importance of advancing future population-based research that includes detailed information on the health and well-being of SMs in the United States.
