RESUMO
BACKGROUND: Previous studies have identified a violence typology of self- and other-directed violence. This study examines the extent to which substance use disorders (SUDs) as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), independent of serious psychological distress, major depressive episodes, assault arrest, and criminal justice involvement, are associated with these violence categories. METHOD: Data were obtained from the National Survey on Drug Use and Health (NSDUH) pooled across survey years 2008-2015, with a combined sample of 314,881 adult respondents. According to self-report data on suicide attempt (self-directed) and attacking someone with the intent for serious injury (other-directed), violence was categorized in four categories: none, self-directed only, other-directed only, and combined self-/other-directed. Multinomial logistic regression was used to estimate the adjusted odds ratios associated with the risk factors for different forms of violence. RESULTS: Nicotine dependence and the number of DSM-IV SUDs criteria (except the criterion of legal problems) for alcohol, marijuana, and pain reliever use disorders are significantly associated with the self-/other-directed violence categories. LIMITATIONS: Cross-sectional data do not allow assessment of directionality of important factors. CONCLUSIONS: The identification of the combined self- and other-directed violence among adults in the general population extends studies in the adolescent population, and significant correlation between self- and other-directed violence provides additional support for clinical studies that established this association. Findings expand the associated risk factors identified in previous studies for the adult population. Prevention and treatment programs need to address both forms of violence and suicidality.

INTRODUCTION: Alcohol dependence (AD) presents with substantial clinical heterogeneity, including concurrent use of non-alcohol drugs. Here, we examine specific patterns of concurrent non-alcohol substance use during the previous year among a nationally representative sample of adults with DSM-IV AD, and estimate their population prevalence in the U.S. We then evaluate alcohol use behavior and comorbid psychopathology among respondents with AD according to their patterns of concurrent non-alcohol substance use. METHODS: These analyses utilized data from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Latent class analyses classified respondents with AD into four clinically meaningful patterns of concurrent substance use: (1) use of alcohol only; (2) use of alcohol and tobacco only; (3) use of alcohol, tobacco and cannabis; and (4) use of alcohol, tobacco, cannabis, cocaine, and other illicit drug(s). RESULTS: Among AD respondents, the most prevalent pattern was the use of alcohol and tobacco only (weighted percentage, 32.4%), followed by the use of alcohol only (weighted percentage, 27.5%). AD respondents who used alcohol, tobacco, cannabis, cocaine, and other illicit drug(s) (weighted percentage, 25.3%) manifested the most severe pattern of alcohol consumption, and had significant overrepresentations of major depression, panic, and other anxiety disorders as well as paranoid, schizotypal, borderline, antisocial, and histrionic personality disorders compared with those who used alcohol alone. CONCLUSIONS: Specific patterns of concurrent substance use convey important information regarding the clinical presentation and prognosis for AD. In particular, concurrent use of illicit drugs over the past year by AD individuals was associated with greater severity and comorbid psychopathology. These data suggest the need for pragmatic trials of AD interventions that take into account patterns of substance use behavior in addition to an AD diagnosis.

BACKGROUND: Few epidemiologic studies have examined a full range of adolescent psychiatric disorders in the general population. The association between psychiatric symptom clusters (PSCs) and DSM-IV alcohol use disorders (AUDs) among adolescents is not well understood. METHODS: This study draws upon the public-use data from the 2000 National Household Survey on Drug Abuse, including a study sample of 19,430 respondents aged 12 to 17. Logistic regression and exploratory structural equation modeling assess the associations between PSCs and DSM-IV AUDs by gender. The PSCs are based on brief screening scales devised from the Diagnostic Interview Schedule for Children Predictive Scales. RESULTS: Several PSCs were found to be significantly associated with DSM-IV AUDs, including separation anxiety, generalized anxiety, depression, oppositional defiant disorder, and conduct disorder among both genders, and panic disorder and obsessive/ compulsive disorder among females. Consistent with the literature, the analysis of PSCs yields 3 factors identical for both genders-2 internalizing factors (fear and anxiety-misery) and 1 externalizing factor. Adolescents who scored higher on the externalizing factor tended to have higher levels of the AUD factor. Female adolescents who scored higher on the internalizing misery factor and lower on the internalizing fear factor also tended to have higher levels of the AUD factor. CONCLUSIONS: The associations that we found between PSCs and AUDs among adolescents in this study are consistent with those found among adults in other studies, although gender may moderate associations between internalizing PSCs and AUDs. Our findings lend support to previous findings on the developmentally stable associations between disruptive behaviors and AUDs among adolescents as well as adults in the general population.

OBJECTIVE: We used motor vehicle traffic (MVT) crash fatalities as an example to examine the extent of underreporting of alcohol involvement on death certificates and state variations. METHOD: We compared MVT-related death certificates identified from national mortality data (Multiple Cause of Death [MCoD] data) with deaths in national traffic census data from the Fatality Analysis Reporting System (FARS). Because MCoD data were not individually linked to FARS data, the comparisons were at the aggregate level. Reporting ratio of alcohol involvement on death certificates was thus computed as the prevalence of any mention of alcohol-related conditions among MVT deaths in MCoD, divided by the prevalence of decedents with blood alcohol concentration (BAC) test results (not imputed) of .08% or greater in FARS. Through bivariate analysis and multiple regression, we explored state characteristics correlated with state reporting ratios. RESULTS: Both MCoD and FARS identified about 450,000 MVT deaths in 1999-2009. Reporting ratio was only 0.16 for all traffic deaths and 0.18 for driver deaths nationally, reflecting that death certificates captured only a small percentage of MVT deaths involving BAC of .08% or more. Reporting ratio did not improve over time, even though FARS indicated that the prevalence of BAC of at least .08% in MVT deaths increased from 19.9% in 1999 to 24.2% in 2009. State reporting ratios varied widely, from 0.02 (Nevada and New Jersey) to 0.81 (Delaware). CONCLUSIONS: The comparison of MCoD with FARS revealed a large discrepancy in reporting alcohol involvement in MVT deaths and considerable state variation in the magnitude of underreporting. We suspect similar underreporting and state variations in alcohol involvement in other types of injury deaths.

The aim of this study is to examine associations among childhood physical, emotional, or sexual abuse and violence toward self (suicide attempts [SA]) and others (interpersonal aggression [IA]). Data were obtained from the National Epidemiologic Survey on Alcohol and Related Conditions Waves 1 and 2 (n=34,653). Multinomial logistic regression examined associations between type of childhood abuse and violence categories, adjusting for demographic variables, other childhood adversity, and DSM-IV psychiatric disorders. The prevalence of reported childhood abuse was 4.60% for physical abuse, 7.83% for emotional abuse, and 10.20% for sexual abuse. Approximately 18% of adults reported some form of violent behavior, distributed as follows: IA, 13.37%; SA, 2.64%; and SA with IA, 1.85%. After adjusting for demographic variables, other childhood adversity, and psychiatric disorders, each type of childhood abuse was significantly related to increased risk for each violence category as compared with the no violence category. Furthermore, the odds ratio of childhood physical abuse was significantly higher for SA with IA when compared with IA, and the odds ratio of childhood sexual abuse was significantly higher for SA and SA with IA when compared with IA. Childhood physical, emotional, and sexual abuse is directly related to the risk for violent behaviors to self and others. Both internalizing and externalizing psychiatric disorders impact the association between childhood abuse and violence. The inclusion of suicidal behaviors and interpersonal aggression and internalizing/externalizing psychiatric disorders within an integrated conceptual framework will facilitate more effective interventions for long-lasting effects of child abuse.

BACKGROUND: Alcohol, tobacco and marijuana are the most commonly used drugs by adolescents in the U.S. However, little is known about the patterning of early adolescent substance use, and its implications for problematic involvement with substances in young adulthood. We examined patterns of substance use prior to age 16, and their associations with young adult substance use behaviors and substance use disorders in a nationally representative sample of U.S. adolescents. METHOD: Using data from Wave 4 of the Add Health Survey (n=4245), we estimated the prevalence of various patterns of early adolescent use of alcohol, cigarettes, and marijuana use individually and in combination. Then we examined the effects of patterns of early use of these substances on subsequent young adult substance use behaviors and DSM-IV substance use disorders. RESULTS: While 34.4% of individuals reported no substance use prior to age 16, 34.1% reported either early use of both alcohol and marijuana or alcohol, marijuana and cigarettes, indicating the relatively high prevalence of this type of polysubstance use behavior among U.S. adolescents. Early adolescent use of all three substances was most strongly associated with a spectrum of young adult substance use problems, as well as DSM-IV substance use disorder diagnoses. CONCLUSIONS: This research confirms the elevated prevalence and importance of polysubstance use behavior among adolescents prior to age 16, and puts early onset of alcohol, marijuana and cigarette use into the context of use patterns rather than single drug exposures.

OBJECTIVE: To examine unintentional alcohol and drug poisoning in association with substance use disorders (SUDs) and mood and anxiety disorders. METHOD: International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) external-cause-of-injury codes on discharge records of patients ages 12+ years from the 2010 Nationwide Inpatient Sample were examined to identify cases with unintentional alcohol poisoning (E860) and/or drug poisoning (E850-E858). ICD-9-CM diagnosis codes were examined to identify comorbid alcohol dependence, drug dependence, tobacco use disorder, and mood/anxiety disorders. Poisson regression was used to derive risk ratios to assess the associations between these comorbid conditions and alcohol/drug poisoning. RESULTS: Estimated numbers of hospitalisations related to unintentional alcohol and drug poisoning were, respectively, 5623 and 60 423 in men, and 3147 and 68 568 in women. For both sexes, the proportion with SUDs or mood/anxiety disorders was significantly higher among inpatients with alcohol and drug poisoning than among all inpatients. Estimated risk ratios indicated strong relationships of SUDs and mood/ anxiety disorders with unintentional poisoning from alcohol and drugs. The strongest association was between alcohol dependence and alcohol poisoning for both sexes. Significant associations also existed between drug dependence and drug poisoning, and mood/anxiety disorders and poisoning from alcohol and drugs. CONCLUSIONS: SUDs and mood/anxiety disorders are key risk factors for unintentional poisoning by alcohol and drugs among inpatients in the USA. Effective treatments of these disorders should be targeted as poisoning prevention efforts. Future studies are needed to clarify a potential bias in the data due to differential inpatient mental condition screening practices.

BACKGROUND: The placebo effect often undermines efforts to determine treatment effectiveness in clinical trials. A significant placebo response occurs in alcohol trials, but it is not well understood. The purpose of this study was to characterize the placebo response across multiple naltrexone and acamprosate studies. METHODS: Fifty-one trials, 3 with a naltrexone and an acamprosate arm, 31 with at least 1 naltrexone arm, and 17 with at least 1 acamprosate arm, were identified from Cochrane reviews and PubMed search. To be included in this study, patients had to be at least 18 years old, abstinent from alcohol before randomization, and meet a diagnosis of alcohol dependence. Pearson correlation coefficients (rp ) and simple linear regression were used to describe the strength of linear relationships between placebo response and treatment effect size. Spearman's rank correlation coefficients (rs ) were used to examine the strength of associations between study characteristics and placebo response. RESULTS: For the end point measures of percent days abstinent and total abstinence, a negative relationship was evident between placebo response and treatment effect size in the naltrexone trials (rp = -0.55, p < 0.01 and rp = -0.20, p = 0.35, respectively) as well as in the acamprosate trials (rp = -0.45, p = 0.09 and rp = -0.56, p = 0.01, respectively). The placebo response for percent days abstinent was negatively correlated with mean age of participants (rs = -0.42, p = 0.05) across naltrexone trials and positively correlated with publication year (rs = 0.57, p = 0.03) across acamprosate trials. However, these 2 study characteristics were not significantly correlated with treatment effect size. CONCLUSIONS: The placebo response varied considerably across trials and was negatively correlated with the treatment effect size. Additional studies are required to fully understand the complex nature of the placebo response and to evaluate approaches to minimize its effects.

OBJECTIVE: To examine associations between DSM-IV psychiatric disorders and other- and self-directed violence in the general population. METHODS: Data were obtained from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) Waves 1 & 2 (n=34,653). Four violence categories were derived from a latent class analysis (LCA) of 5 other-directed and 4 self-directed violent behavior indicators. Multinomial logistic regression examined class associations for gender, race-ethnicity, age and DSM-IV substance use, mood, anxiety, and personality disorders. RESULTS: Approximately 16% of adults reported some form of violent behavior distributed as follows: other-directed only, 4.6%; self-directed only, 9.3%; combined self- and other-directed, 2.0%; and no violence, 84.1%. The majority of the DSM-IV disorders included in this study were significantly and independently related to each form of violence. Generally, other-directed violence was more strongly associated with any substance use disorders (81%) and any personality disorders (42%), while self-directed violence was more strongly associated with mood (41%) and anxiety disorders (57%). Compared with these two forms of violence, the smaller group with combined self- and other-directed violence was more strongly associated with any substance use disorders (88%), mood disorders (63%), and personality disorders (76%). CONCLUSION: Findings from this study are consistent with recent conceptualizations of disorders as reflecting externalizing disorders and internalizing disorders. The identification of the small category with combined forms of violence further extends numerous clinical studies which established associations between self- and other-directed violent behaviors. The extent to which the combined violence category represents a meaningful and reliable category of violence requires further detailed studies.

OBJECTIVES: We assessed the effect of internal possession (IP) laws, which allow law enforcement to charge underage drinkers with alcohol possession if they have ingested alcohol, on underage drinking behaviors. METHODS: We examined Youth Risk Behavior Survey (YRBS) data from 12 states with IP laws and with YRBS data before and after each law's implementation. We used logistic regression models with fixed effects for state to assess the effects of IP laws on drinking and binge drinking among high school students. RESULTS: Implementation of IP laws is associated with reductions in the odds of past-month drinking. This reduction was bigger among male than among female adolescents (27% vs 15%) and only significant among younger students aged 14 and 15 years (15% and 11%, respectively). Male adolescents also reported a significant reduction (24%) in the odds of past-month binge drinking under IP laws. CONCLUSIONS: These findings suggest that IP laws are effective in reducing underage drinking, particularly among younger adolescents.

To describe prevalence trends in hospitalized live births affected by placental transmission of alcohol and drugs, as well as prevalence trends among parturient women hospitalized for liveborn delivery and diagnosed with substance abuse problems in the United States from 1999 to 2008. Comparison of the two sets of trends helps determine whether the observed changes in neonatal problems over time were caused by shifts in maternal substance abuse problems. This study independently identified hospitalized live births and maternal live born deliveries from discharge records in the Nationwide Inpatient Sample, one of the largest hospital administrative databases. Substance-related diagnosis codes on the records were used to identify live births affected by alcohol and drugs and parturient women with substance abuse problems. The analysis calculated prevalence differences and percentage changes over the 10 years, with Loess curves fitted to 10-year prevalence estimates to depict trend patterns. Linear and quadratic trends in prevalence were simultaneously tested using logistic regression analyses. The study also examined data on costs, primary expected payer, and length of hospital stays. From 1999 to 2008, prevalence increased for narcotic- and hallucinogen-affected live births and neonatal drug withdrawal syndrome but decreased for alcohol- and cocaine-affected live births. Maternal substance abuse at delivery showed similar trends, but prevalence of alcohol abuse remained relatively stable. Substance-affected live births required longer hospital stays and higher medical expenses, mostly billable to Medicaid. The findings highlight the urgent need for behavioral intervention and early treatment for substance-abusing pregnant women to reduce the number of substance-affected live births.

OBJECTIVE: Neither the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised (DSM-III-R), nor the DSM-IV uses measures of substance consumption as part of the diagnostic criteria for substance use disorders. Therefore, this report examined the extent to which frequency and/or quantity of consumption across a broad spectrum of substances are associated with DSM-IV diagnoses of specific substance use disorders and whether there are informative hierarchical levels of consumption among users, abusers, and those who are substance dependent in the U.S. general population. METHOD: The analyses focused on consumption data from respondents of the 2001-2002 National Epidemiologic Survey of Alcohol and Related Disorders. Multinomial logistic regression was used to predict DSM-IV diagnoses of dependence or abuse based on the continuous consumption measures. RESULTS: Among individuals who used substances, the substances with the greatest liability for dependence were nicotine first and cocaine second. For nearly all substances investigated, users without specific substance use disorders demonstrated lower levels of quantity and frequency of consumption relative to those with DSM-IV abuse and dependence disorders. Dose-response curves for the log odds of abuse and dependence suggested unidimensionality of abuse and dependence for frequency of alcohol drinking; frequency of cannabis use; frequency of opioid use; frequency of hallucinogen use; and, to a lesser extent, frequency of amphetamine use. However, the dose-response curves for the quantity of alcohol consumed demonstrated differential patterns for abuse and dependence such that alcohol dependence has a distinctly greater "quantity of use" relationship than that found among alcohol-abusing individuals. CONCLUSIONS: These results confirm the findings of others concerning the unidimensionality of abuse and dependence diagnoses when consumption variables alone are examined and suggest that consumption measures may be useful metrics gauging severity.

OBJECTIVE: Premised on biological evidence from animal research, recent clinical studies have, for the most part, concluded that elevated blood alcohol concentration levels are independently associated with higher survival or decreased mortality in patients with moderate to severe traumatic brain injury (TBI). This study aims to provide some counterevidence to this claim and to further future investigations. METHOD: Incident data were drawn from the largest U.S. trauma registry, the National Trauma Data Bank, for emergency department admission years 2002-2006. TBI was identified according to the National Trauma Data Bank's definition using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), codes. To eliminate confounding, the exact matching method was used to match alcohol-positive with alcohol-negative incidents on sex, age, race/ethnicity, and facility. Logistic regression compared in-hospital mortality between 44,043 alcohol-positive and 59,817 matched alcohol-negative TBI incidents, with and without causes and intents of TBI and Injury Severity Score as covariates. A sensitivity analysis was performed within a subsample of isolated moderate to severe TBI incidents. RESULTS: Alcohol use at the time of injury was found to be significantly associated with an increased risk for TBI. Including varied causes and intents of TBI and Injury Severity Score as potential confounders in the regression model explained away the statistical significance of the seemingly protective effect of alcohol against TBI mortality for all TBIs and for isolated moderate to severe TBIs. CONCLUSIONS: The null finding shows that the purported reduction in TBI mortality attributed to positive blood alcohol likely is attributable to residual confounding. Accordingly, the risk of TBI associated with alcohol use should not be overlooked.

This study examined associations between binge drinking and other substance use and perpetration of violence against self and others. Data were pooled from the 2003, 2005, and was constructed to reflect four categories of behaviors: other-directed violence only, self-directed violence only, combined other- and self-directed violence, and no violence. Results from multinomial logistic regressions show that the frequency of binge drinking and other substance use were significant risk factors for each of the violence categories relative to no-violence. However, the strengths of these associations varied across the violence categories.
RESUMO
OBJECTIVE: The incidence rate of hepatocellular carcinoma has been rising in the United States during the last 2 decades. Heavy alcohol use has been widely recognized as one of the major etiological factors of hepatocellular carcinoma. This study sought to assess the extent to which heavy alcohol use contributed to premature death from hepatocellular carcinoma on a population scale in the United States. METHOD: We analyzed the Multiple Cause of Death public-use data sets. Using codes from the International Classification of Diseases, 10th Revision, hepatocellular carcinoma death was defined based on the underlying cause of death, and heavy alcohol use was indicated by the presence of any alcohol-induced medical conditions among the contributing causes of death. During 1999-2006 in the United States, 51,400 hepatocellular carcinoma deaths were identified from 17,727,245 natural deaths of persons age 25 or older. We conducted Poisson regression, life table, and multiple linear regression analyses to compare prevalence ratios, cumulative probabilities, and mean ages of death, respectively, from hepatocellular carcinoma by heavy alcohol use status across sex and race/ethnicity. RESULTS: Heavy alcohol use decedents had higher prevalence ratios of dying from hepatocellular carcinoma than from non-chronic liver diseases compared with those decedents without heavy alcohol use. Heavy alcohol use was associated with decreased mean ages and increased cumulative probabilities of death among hepatocellular carcinoma decedents across racial/ethnic groups in both sexes. This association was stronger among women than men and stronger among non-Hispanic Whites than non-Hispanic Blacks. CONCLUSIONS: This study provides mortality-based empirical evidence to further establish heavy alcohol consumption as one of the key risk factors contributing to premature deaths from hepatocellular carcinoma in the United States, and its effect appears more prominent among women and non-Hispanic Whites.

OBJECTIVE: Recent reports indicate an increase in rates of hospitalizations for drug overdoses in the United States. The role of alcohol in hospitalizations for drug overdoses remains unclear. Excessive consumption of alcohol and drugs is prevalent in young adults ages 18-24. The present study explores rates and costs of inpatient hospital stays for alcohol overdoses, drug overdoses, and their co-occurrence in young adults ages 18-24 and changes in these rates between 1999 and 2008. METHOD: Data from the Nationwide Inpatient Sample were used to estimate numbers, rates, and costs of inpatient hospital stays stemming from alcohol overdoses (and their subcategories, alcohol poisonings and excessive consumption of alcohol), drug overdoses (and their subcategories, drug poisonings and nondependent abuse of drugs), and their co-occurrence in 18- to 24-year-olds. RESULTS: Hospitalization rates for alcohol overdoses alone increased 25% from 1999 to 2008, reaching 29,412 cases in 2008 at a cost of $266 million. Hospitalization rates for drug overdoses alone increased 55%, totaling 113,907 cases in 2008 at a cost of $737 million. Hospitalization rates for combined alcohol and drug overdoses increased 76%, with 29,202 cases in 2008 at a cost of $198 million. CONCLUSIONS: Rates of hospitalizations for alcohol overdoses, drug overdoses, and their combination all increased from 1999 to 2008 among 18- to 24-year-olds. The cost of such hospitalizations now exceeds $1.2 billion annually. The steepest increase occurred among cases of combined alcohol and drug overdoses. Stronger efforts are needed to educate medical practitioners and the public about the risk of overdoses, particularly when alcohol is combined with other drugs.

OBJECTIVE: The aim of this study was to quantify the effect of comorbid alcohol and drug use disorders on premature death, as reflected by the manner of death (suicide and other unnatural death versus natural death) and the age at death, among decedents with unipolar and bipolar disorders. METHODS: This study is based on the US Multiple Cause of Death public-use data files for 1999 to 2006. Secondary data analysis was conducted comparing decedents with unipolar/bipolar disorders and decedents with all other causes of death, based on the death records of 19,052,468 decedents in the Multiple Cause of Death data files who died at 15 years and older. Poisson regression models were used to derive prevalence ratios to assess the effect of comorbid substance use disorders (SUD) on the risks for being an unnatural death among mood disorder deaths. Multiple-cause life table analysis and mean age at death were used to quantify the effect of comorbid SUDs on premature mortality among mood disorder deaths. RESULTS: Prevalence of comorbid SUDs was higher among unipolar and bipolar disorder deaths than that among all other deaths. Among unipolar and bipolar disorder deaths, comorbid SUDs were associated with elevated risks for suicide and other unnatural death in both men and women (prevalence ratios ranging 1.49-9.46, P < .05). They also were associated with reductions in mean ages at death (ranging 11.7-33.8 years, P < .05). In general, these effects were much stronger for drug use disorders than for alcohol use disorders. Both SUDs had stronger effects on suicide among women, whereas their effects on other unnatural deaths were stronger among men. CONCLUSIONS: This study is among the first to provide population mortality-based evidence to further establish comorbid SUD as one of the key risk factors for premature death among individuals with unipolar or bipolar disorders in the United States. Clinicians need to be aware of the potentially lethal risk associated with these comorbid conditions.

BACKGROUND: Hispanics have much higher cirrhosis mortality rates than non-Hispanic Blacks and Whites. Although heavy alcohol use and hepatitis C virus (HCV) infection are two major risk factors for cirrhosis, no studies have systematically assessed the contribution of alcohol- and HCV-related cirrhosis deaths to the total cirrhosis mortality for Hispanics as a whole and its variations across Hispanic subgroups. To fill this gap, this study presents the latest data on total cirrhosis mortality as well as its component alcohol- and HCV-related cirrhosis mortality for all Hispanics and for Hispanic subgroups. METHODS: The multiple-cause approach was used to analyze data from the U.S. Multiple Cause of Death Data Files for 28,432 Hispanics and 168,856 non-Hispanic Whites (as a comparison group) who died from cirrhosis as the underlying or a contributing cause during 2000-2004. Four major Hispanic subgroups were defined by national origin or ancestry, including Mexicans, Puerto Ricans, Cubans, and Other Hispanics. The cirrhosis deaths were divided into four distinctive cause-of-death categories: alcohol-related, HCV-related, both alcohol- and HCV-related, and neither alcohol- nor HCV-related. Age-adjusted total cirrhosis death rates and percentage shares of the cause-specific categories were compared across Hispanic subgroups and non-Hispanic Whites. RESULTS: Compared with non-Hispanic Whites, all Hispanic subgroups except Cubans had much higher cirrhosis mortality. The age-adjusted total cirrhosis death rates were twice as high for Puerto Ricans and Mexicans as for non-Hispanic Whites. Alcohol-related and HCV-related cirrhosis death rates also were higher for most Hispanic subgroups than for non-Hispanic Whites. CONCLUSIONS: Heavy alcohol use and hepatitis C viral infection are two important factors contributing to the high cirrhosis mortality among Hispanics. However, their relative contributions to total cirrhosis mortality varied by gender and Hispanic subgroup. This information is useful for targeted prevention and intervention efforts to address the excessive cirrhosis mortality in the Hispanic population.

BACKGROUND: We have previously reported on an empirical classification of Alcohol Dependence (AD) individuals into subtypes using nationally representative general population data from the 2001 to 2002 Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and latent class analysis. Our results suggested a typology of 5 separate clusters based upon age of onset of AD, multigenerational familial AD, rates of antisocial personality disorder (ASPD), endorsement of specific AD and Alcohol Abuse (AA) criteria, and the presence of comorbid mood, anxiety, and substance use disorders (SUD). In this report, we focus on the clinical follow-up of these cluster members in Wave 2 of the NESARC (2004 to 2005). METHODS: The mean interval between NESARC Wave 1 and NESARC Wave 2 interviews was 36.6 (SD = 2.6) months. For these analyses, we utilized a Wave 2 NESARC sample that was comprised of a total of 1,172 individuals who were initially ascertained as having past-year AD at NESARC Wave 1 and initially subtyped into one of 5 groupings using latent class analysis. We identified these subtypes as: (i) Young Adult, characterized by very early age of onset, minimal family history, and low rates of psychiatric and SUD comorbidity; (ii) Functional, characterized by older age of onset, higher psychosocial functioning, minimal family history, and low rates of psychiatric and SUD comorbidity; (iii) Intermediate Familial, characterized by older age of onset, significant familial AD, and elevated comorbid rates of mood disorders SUD; (iv) Young Antisocial, characterized by early age of onset and elevated rates of ASPD, significant familial AD, and elevated rates of comorbid mood disorders and SUD; (v) Chronic Severe, characterized by later onset, elevated rates of ASPD, significant familial AD, and elevated rates of comorbid mood disorders and SUD. In this report, we examine Wave 2 recovery status, health status, alcohol consumption behavior, and treatment episodes based upon these subtypes. RESULTS: Significantly fewer of the Young Adult and Functional subtypes continued to meet full DSM-IV AD criteria in Wave 2 than did the Intermediate Familial, the Young Antisocial, and the Chronic Severe subtypes. However, we did not find that treatment seeking for alcohol problems increased over Wave 1 reports. In Wave 2, Young Antisocial and Chronic Severe subtypes had highest rates of past-year treatment seeking. In terms of health status, the Intermediate Familial, the Young Antisocial, and the Chronic Severe subtypes had significantly worse mental health scores than the Young Adult and Functional subtypes. For physical health status, the Functional, Intermediate Familial, Young Antisocial, and the Chronic Severe subtypes had significantly worse scores than the Young Adult subtype. In terms of alcohol consumption behavior, the Young Adult, Functional, and Young Antisocial subtypes significantly reduced their risk drinking days between Wave 1 and Wave 2, whereas the Intermediate Familial and the Chronic Severe subtypes did not. DISCUSSION: The results suggest that the empirical AD typology predicts differential clinical outcomes 3 years later. Persistence of full AD, treatment seeking, and worse mental health status were associated most strongly with those subtypes manifesting the greatest degree of psychiatric comorbidity. Reductions in alcohol consumption behavior and good physical health status were seen among the 2 younger subtypes. Overall, the least prevalent subtype, the Chronic Severe, showed the greatest stability in the manifestations of AD, despite having the highest rate of treatment seeking.

OBJECTIVE: This study was conducted to assess the association of "diagnostic orphans" at baseline and subsequent development of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol use disorders (AUDs) 5 years later. METHOD: A sample of 8,534 respondents was drawn from the National Longitudinal Survey of Youth for the years 1989 and 1994. Diagnostic orphans were defined as respondents who met one or two alcohol dependence symptom criteria but did not meet the criteria for a diagnosis of alcohol abuse or dependence. Using multinomial logistic regression analysis, 1994 assessments of DSM-IV AUD were regressed on 1989 baseline assessments of diagnostic orphan status and DSM-IV AUD. In addition to demographic characteristics, other background variables included heavy episodic drinking at baseline and early problem behaviors (antisocial behaviors, illicit substance use, and age at onset of alcohol use). RESULTS: Findings from this 5-year prospective study indicate that diagnostic orphan status at baseline was predictive of DSM-IV AUD at follow-up. These associations remained significant when other early behavioral problems were included in the models. CONCLUSIONS: The present findings have important diagnostic implications for the proposed DSM-V, particularly for a dimensional diagnosis incorporating less severe forms of alcohol dependence.
