Alcohol use disorders and perceived drinking norms: ethnic differences in Israeli adults

OBJECTIVE

Individuals' perceptions of drinking acceptability in their society (perceived injunctive drinking norms) are widely assumed to explain ethnic group differences in drinking and alcohol use disorders (AUDs), but this has never been formally tested. Immigrants to Israel from the former Soviet Union (FSU) are more likely to drink and report AUD symptoms than other Israelis. We tested perceived drinking norms as a mediator of differences between FSU immigrants and other Israelis in drinking and AUDs.

METHOD

Adult household residents (N = 1,349) selected from the Israeli population register were assessed with a structured interview measuring drinking, AUD symptoms, and perceived drinking norms. Regression analyses were used to produce odds ratios (OR) and risk ratios (RR) and 95% confidence intervals (CI) to test differences between FSU immigrants and other Israelis on binary and graded outcomes. Mediation of FSU effects by perceived drinking norms was tested with bootstrapping procedures.

RESULTS

FSU immigrants were more likely than other Israelis to be current drinkers (OR = 2.39, CI [1.61, 3.55]), have higher maximum number of drinks per day (RR = 1.88, CI [1.64, 2.16]), have any AUD (OR = 1.75, CI [1.16, 2.64]), score higher on a continuous measure of AUD (RR = 1.44, CI [1.12, 1.84]), and perceive more permissive drinking norms (p < .0001). For all four drinking variables, the FSU group effect was at least partially mediated by perceived drinking norms.

CONCLUSIONS

This is the first demonstration that drinking norms mediate ethnic differences in AUDs. This work contributes to understanding ethnic group differences in drinking and AUDs, potentially informing etiologic research and public policy aimed at reducing alcohol-related harm.

Stressful Life Events and Relapse Among Formerly Alcohol Dependent Adults

We examined associations between stressful life events and relapse among adults in the United States with at least 1 year of remission from DSM-IV alcohol dependence. The sample consisted of individuals in remission from alcohol dependence at the Wave 1 interview (2001-2002) for the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) who also participated in a Wave 2 interview (2004-2005; N 1,707). Associations between stressful life events, demographic variables, = and the binary outcome of alcohol dependence relapse were examined with multiple logistic regression models. After adjustment for potential confounders, respondents who were divorced or separated in the year preceding the baseline assessment (Wave 1) were over two times more likely (OR = 2.32; CI = 1.01-5.34) to have relapsed 3 years later (Wave 2), compared to those not experiencing a divorce/separation in the 12 months prior to Wave 1. No other stressful life event was associated with relapse. Findings suggest that formerly alcohol dependent adults are at increased risk for relapse following divorce/separation. These results highlight the need for social work practitioners to consider the possibility of relapse following a divorce when one or both partners have a history of alcohol dependence.

Do socio-economic gradients in smoking emerge differently across time by gender? Implications for the tobacco epidemic from a pregnancy cohort in California, USA

Understanding current patterns of population smoking by socioeconomic position (SEP) can be substantially enhanced by research that follows birth cohorts over long periods of time, yet such data in the US are rare. Information from birth cohorts followed during critical time periods when the health consequences of smoking became widely known can inform the ways in which current smoking prevalence has been shaped by the historical processes that preceded it. The present study utilizes data from a substudy of the Child Health and Development Study pregnancy cohort (N = 1612). Women were queried about smoking status in 1959-1962, 1971-1972 and 1977-1980. Women were divided into three cohorts based on date of birth. Offspring represented another birth cohort assessed for smoking in 1977-1980. Results indicated that the overall prevalence of smoking exhibited cohort-specific patterns that persisted across time. Notably, the youngest maternal cohort (born 1937-1946) had high smoking prevalence throughout and showed no appreciable decrease (44.7%, 41.4%, 40.1% for 1959-1962, 1971-1972, and 1977-1980). Results also indicated that the relation of smoking to SEP exhibited cohort-specific patterns over time. Among the oldest birth cohort (born 1914-1930), no inverse relation of SEP to smoking was observed at any time; in contrast, an inverse relation emerged by 1959-1962 among the youngest cohort of mothers. Among the adolescent offspring, there was a strong SEP gradient (OR = 2.0, 95% CI = 1.4-3.0) that was stronger than in any maternal birth cohort at any assessment (β = 0.40, SE = 0.1, p<0.01). We conclude that SEP gradients in smoking emerge across birth cohorts rather than time alone, with increasingly strong gradients across time especially among younger cohorts.

The structure and predictive validity of the internalizing disorders

Multivariate comorbidity research indicates mood and anxiety (internalizing) disorders share one or more common liabilities, but categorical, dimensional, and hybrid accounts of these liabilities have not been directly compared. We modeled seven internalizing disorders in a nationally representative sample of 43,093 individuals via confirmatory factor, latent class, exploratory factor mixture, and exploratory structural equation modeling analyses. A two-dimensional (distress-fear) liability structure fit best and replicated across gender, assessment waves, and lifetime/12-month diagnoses. These liabilities, not disorder-specific variation, predicted future internalizing pathology, suicide attempts, angina, and ulcer.

Home foreclosure and risk of psychiatric morbidity during the recent financial crisis

BACKGROUND

A defining feature of the US economic downturn of 2008-2010 was the alarming rate of home foreclosure. Although a substantial number of US households have experienced foreclosure since 2008, the effects of foreclosure on mental health are unknown. We examined the effects of foreclosure on psychiatric symptomatology in a prospective, population-based community survey.

METHOD

Data were drawn from the Detroit Neighborhoods and Health Study (DNHS), waves 1 and 2 (2008-2010). A probability sample of predominantly African-American adults in Detroit, Michigan participated (n=1547). We examined the association between home foreclosure between waves 1 and 2 and increases in symptoms of DSM-IV major depression and generalized anxiety disorder (GAD).

RESULTS

The most common reasons for foreclosure were an increase in monthly payments, an increase in non-medical expenses and a reduction in family income. Exposure to foreclosure between waves 1 and 2 predicted symptoms of major depression and GAD at wave 2, controlling for symptoms at wave 1. Even after adjusting for wave 1 symptoms, sociodemographics, lifetime history of psychiatric disorder at wave 1 and exposure to other financial stressors between waves 1 and 2, foreclosure was associated with an increased rate of symptoms of major depression [incidence density ratio (IDR) 2.4, 95% confidence interval (CI) 1.6-3.6] and GAD (IDR 1.9, 95% CI 1.4-2.6).

CONCLUSIONS

We provide the first prospective evidence linking foreclosure to the onset of mental health problems. These results, combined with the high rate of home foreclosure since 2008, suggest that the foreclosure crisis may have adverse effects on the mental health of the US population.

Mood and anxiety disorders and their association with non-medical prescription opioid use and prescription opioid-use disorder: longitudinal evidence from the National Epidemiologic Study on Alcohol and Related Conditions

BACKGROUND

Non-medical use of prescription opioids represents a national public health concern of growing importance. Mood and anxiety disorders are highly associated with non-medical prescription opioid use. The authors examined longitudinal associations between non-medical prescription opioid use and opioid disorder due to non-medical opioid use and mood/anxiety disorders in a national sample, examining evidence for precipitation, self-medication and general shared vulnerability as pathways between disorders.

METHOD

Data were drawn from face-to-face surveys of 34 653 adult participants in waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions. Logistic regression models explored the temporal sequence and evidence for the hypothesized pathways.

RESULTS

Baseline lifetime non-medical prescription opioid use was associated with incidence of any mood disorder, major depressive disorder (MDD), bipolar disorder, any anxiety disorder and generalized anxiety disorder (GAD in wave 2, adjusted for baseline demographics, other substance use, and co-morbid mood/anxiety disorders). Lifetime opioid disorder was not associated with any incident mood/anxiety disorders. All baseline lifetime mood disorders and GAD were associated with incident non-medical prescription opioid use at follow-up, adjusted for demographics, co-morbid mood/anxiety disorders, and other substance use. Baseline lifetime mood disorders, MDD, dysthymia and panic disorder were associated with incident opioid disorder due to non-medical prescription opioid use at follow-up, adjusted for the same covariates.

CONCLUSIONS

These results suggest that precipitation, self-medication as well as shared vulnerability are all viable pathways between non-medical prescription opioid use and opioid disorder due to non-medical opioid use and mood/anxiety disorders.

Child maltreatment increases sensitivity to adverse social contexts: neighborhood physical disorder and incident binge drinking in Detroit

INTRODUCTION

Exposure to child maltreatment is associated with elevated risk for behavioral disorders in adulthood. One explanation for this life-course association is that child maltreatment increases vulnerability to the effects of subsequent stressors; however, the extent to which maltreatment increases sensitivity to social context has never been examined. We evaluated whether the association between neighborhood physical disorder and binge drinking was modified by child maltreatment exposure.

METHODS

Data were drawn from the Detroit Neighborhood Health Study, a prospective representative sample of predominately African Americans in the Detroit population. Neighborhood physical disorder was measured via systematic neighborhood assessment. Child maltreatment indicators included self-reported physical, sexual, and emotional abuse. Incident binge drinking was defined as at least one episode of ≥5 drinks (men) or ≥4 drinks (women) in the past 30-day period among those with no binge drinking at baseline (N=1013).

RESULTS

Child maltreatment and neighborhood physical disorder interacted to predict incident binge drinking (B=0.16, p=0.02) and maximum number of past 30-day drinks (B=0.15, p=0.04), such that neighborhood physical disorder predicted problematic alcohol use only among individuals with high exposure to child maltreatment.

CONCLUSION

The results add to the growing literature that African Americans in the US are exposed to an array of stressors that have pernicious consequences for problematic alcohol use. Our results document the need for increased attention to the potential for at-risk alcohol use among populations with a high degree of stress exposure.

Childhood maltreatment and the structure of common psychiatric disorders

BACKGROUND

Previous research suggests that various types of childhood maltreatment frequently co-occur and confer risk for multiple psychiatric diagnoses. This non-specific pattern of risk may mean that childhood maltreatment increases vulnerability to numerous specific psychiatric disorders through diverse, specific mechanisms or that childhood maltreatment engenders a generalised liability to dimensions of psychopathology. Although these competing explanations have different implications for intervention, they have never been evaluated empirically.

AIMS

We used a latent variable approach to estimate the associations of childhood maltreatment with underlying dimensions of internalising and externalising psychopathology and with specific disorders after accounting for the latent dimensions. We also examined gender differences in these associations.

METHOD

Data were drawn from a nationally representative survey of 34 653 US adults. Lifetime DSM-IV psychiatric disorders were assessed using the AUDADIS-IV. Physical, sexual and emotional abuse and neglect were assessed using validated measures. Analyses controlled for other childhood adversities and sociodemographics.

RESULTS

The effects were fully mediated through the latent liability dimensions, with an impact on underlying liability levels to internalising and externalising psychopathology rather than specific psychiatric disorders. Important gender differences emerged with physical abuse associated only with externalising liability in men, and only with internalising liability in women. Neglect was not significantly associated with latent liability levels.

CONCLUSIONS

The association between childhood maltreatment and common psychiatric disorders operates through latent liabilities to experience internalising and externalising psychopathology, indicating that the prevention of maltreatment may have a wide range of benefits in reducing the prevalence of many common mental disorders. Different forms of abuse have gender-specific consequences for the expression of internalising and externalising psychopathology, suggesting gender-specific aetiological pathways between maltreatment and psychopathology.

Medical marijuana laws in 50 states: investigating the relationship between state legalization of medical marijuana and marijuana use, abuse and dependence

BACKGROUND

Marijuana is the most frequently used illicit substance in the United States. Little is known of the role that macro-level factors, including community norms and laws related to substance use, play in determining marijuana use, abuse and dependence. We tested the relationship between state-level legalization of medical marijuana and marijuana use, abuse, and dependence.

METHODS

We used the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a national survey of adults aged 18+ (n=34,653). Selected analyses were replicated using the National Survey on Drug Use and Health (NSDUH), a yearly survey of ∼68,000 individuals aged 12+. We measured past-year cannabis use and DSM-IV abuse/dependence.

RESULTS

In NESARC, residents of states with medical marijuana laws had higher odds of marijuana use (OR: 1.92; 95% CI: 1.49-2.47) and marijuana abuse/dependence (OR: 1.81; 95% CI: 1.22-2.67) than residents of states without such laws. Marijuana abuse/dependence was not more prevalent among marijuana users in these states (OR: 1.03; 95% CI: 0.67-1.60), suggesting that the higher risk for marijuana abuse/dependence in these states was accounted for by higher rates of use. In NSDUH, states that legalized medical marijuana also had higher rates of marijuana use.

CONCLUSIONS

States that legalized medical marijuana had higher rates of marijuana use. Future research needs to examine whether the association is causal, or is due to an underlying common cause, such as community norms supportive of the legalization of medical marijuana and of marijuana use.

Cohort effects explain the increase in autism diagnosis among children born from 1992 to 2003 in California

BACKGROUND

The incidence and prevalence of autism have dramatically increased over the last 20 years. Decomposition of autism incidence rates into age, period and cohort effects disentangle underlying domains of causal factors linked to time trends. We estimate an age-period-cohort effect model for autism diagnostic incidence overall and by level of functioning.

METHODS

Data are drawn from sequential cohorts of all 6 501 262 individuals born in California from 1992 to 2003. Autism diagnoses from 1994 to 2005 were ascertained from the California Department of Development Services Client Development and Evaluation Report.

RESULTS

Compared with those born in 1992, each successively younger cohort has significantly higher odds of an autism diagnosis than the previous cohort, controlling for age and period effects. For example, individuals born in 2003 have 16.6 times the odds of an autism diagnosis compared with those born in 1992 [95% confidence interval (CI) 7.8-35.3]. The cohort effect observed in these data is stronger for high than for low-functioning children with an autism diagnosis.

DISCUSSION

Autism incidence in California exhibits a robust and linear positive cohort effect that is stronger among high-functioning children with an autism diagnosis. This finding indicates that the primary drivers of the increases in autism diagnoses must be factors that: (i) have increased linearly year-to-year; (ii) aggregate in birth cohorts; and (iii) are stronger among children with higher levels of functioning.

Estimating risk for suicide attempt: are we asking the right questions? Passive suicidal ideation as a marker for suicidal behavior

BACKGROUND

Desire for death is not generally considered a harbinger of more severe suicidal behavior and is not routinely included in suicide research and assessment interviews. We aimed to compare desire for death and suicidal ideation as clinical markers for suicide attempts.

METHODS

Using data from two nationally representative surveys (n=42,862 and n=43,093 respectively), we examined whether desire for death predicts suicide attempts. We compared the odds ratio (OR) and "Number Needed to be Exposed for one additional person to be Harmed" [NNEH] for lifetime suicide attempts among those with desire for death but no suicidal ideation; those with suicidal ideation but no desire for death, and those with both desire for death and suicidal ideation, compared to those with neither desire for death nor suicidal ideation.

RESULTS

The risk for lifetime suicide attempt was similar among those with lifetime desire for death with no suicidal ideation and those with lifetime suicidal ideation with no desire for death. Respondents with both lifetime desire for death and suicidal ideation had the highest risk for lifetime suicide attempts.

LIMITATIONS

Cross-sectional design and self-reported suicidal ideation/attempts are viewed as limitations of this study.

CONCLUSIONS

Querying individuals on desire for death has the same value as assessing suicidal ideation to examine risk for suicide attempt. A combination of desire for death and suicidal ideation is the best predictor for suicide attempts. This is of high clinical relevance since we suggest that desire for death should be included as a potential clinical marker of suicidality in clinical assessments.

The social norms of birth cohorts and adolescent marijuana use in the United States, 1976-2007

AIMS

Studies of the relationship between social norms and marijuana use have generally focused on individual attitudes, leaving the influence of larger societal-level attitudes unknown. The present study investigated societal-level disapproval of marijuana use defined by birth cohort or by time-period.

DESIGN

Combined analysis of nationally representative annual surveys of secondary school students in the United States conducted from 1976 to 2007 as part of the Monitoring the Future study.

SETTING

In-school surveys completed by adolescents in the United States.

PARTICIPANTS

A total of 986 003 adolescents in grades 8, 10 and 12.

MEASUREMENTS

Main predictors included the percentage of students who disapproved of marijuana in each birth cohort and time-period. Multi-level models with individuals clustered in time-periods of observation and birth cohorts were modeled, with past-year marijuana use as the outcome.

FINDINGS

Results indicated a significant and strong effect of birth cohort disapproval of marijuana use in predicting individual risk of marijuana use, after controlling for individual-level disapproval, perceived norms towards marijuana and other characteristics. Compared to birth cohorts in which most (87-90.9%) adolescents disapproved of marijuana use, odds of marijuana use were 3.53 times higher in cohorts where fewer than half (42-46.9%) disapproved (99% confidence interval: 2.75, 4.53).

CONCLUSIONS

Individuals in birth cohorts that are more disapproving of marijuana use are less likely to use, independent of their personal attitudes towards marijuana use. Social norms and attitudes regarding marijuana use cluster in birth cohorts, and this clustering has a direct effect on marijuana use even after controlling for individual attitudes and perceptions of norms.

Mental health service use by persons of Asian ancestry with DSM-IV mental disorders in the United States

OBJECTIVES

This study compared the prevalence and odds of mental health service utilization among people of Asian ancestry with lifetime DSM-IV mood, anxiety, alcohol, and drug use disorders with utilization by members of other racial and ethnic groups with similar disorders.

METHODS

Between 2001 and 2002, a total of 43,093 noninstitutionalized individuals were assessed by the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) study of lifetime prevalence of DSM-IV psychiatric disorders and mental health service utilization among various ethnic and racial groups.

RESULTS

Among individuals with lifetime mood disorders, Asians had significantly lower mental health service utilization compared with whites (odds ratio [OR]=.31, 95% confidence interval [CI]=.21-.46), Hispanics (OR=.49, CI=.33-71), and Native Americans (OR=.27, CI=.15-.48) but similar utilization compared with blacks. There were no statistically significant differences in lifetime mental health service utilization for alcohol and drug use disorders among racial and ethnic groups.

CONCLUSIONS

Asians with lifetime mood disorders underutilized mental health services even after adjustment was made for socioeconomic variables and years of residency in the United States. Future studies of culture-specific attitudes, correlates, and barriers to mental health service utilization are warranted.

The role of race/ethnicity in alcohol-attributable injury in the United States

A substantial proportion of injuries worldwide are attributable to alcohol consumption, and US estimates indicate that the drinking patterns of racial/ethnic groups vary considerably. The authors reviewed evidence from 19 publications regarding racial/ethnic differences in overall alcohol-attributable injury as well as percent blood alcohol content positivity for injury deaths in the United States. They found that Native Americans evidence higher rates of alcohol-attributable motor vehicle crash fatality, suicide, and falls compared with other racial/ethnic groups; conversely, Asians evidence lower rates of alcohol-attributable injury than other racial/ethnic groups. The rate of alcohol positivity and intoxication among Hispanics is disproportionately high relative to estimates of alcohol use. Black subgroups also evidence higher rates of alcohol positivity than would be expected given estimates of alcohol use, including for alcohol positivity among drivers of fatally injured black children and homicide. These findings highlight the continued need for public health focus on Native American populations with respect to alcohol consumption and injury. Further, the disparity in alcohol-attributable injury mortality among black and Hispanic groups relative to their reported rates of alcohol consumption is an overlooked area of research. The authors review potential social determinants of racial/ethnic disparities in alcohol-attributable injuries and identify directions for further research on these patterns.

Birth cohort effects and gender differences in alcohol epidemiology: a review and synthesis

BACKGROUND

Alcohol consumption has demonstrated substantial temporal trends, with some evidence suggesting strong birth cohort effects. The identification of at-risk birth cohorts can inform the interpretation of alcohol trends across age, time, and demographic characteristics such as gender. The present literature review has 2 objectives. First, we conduct a cross-national review of the literature on birth cohort differences in alcohol consumption, disorder, and mortality. Second, we determine the consistency of evidence for birth cohort effects on gender differences.

METHODS

A search was conducted and key data on population characteristics, presence and direction of cohort effects, and interactions with gender compiled. Thirty-one articles were included.

RESULTS

Evidence suggests that younger birth cohorts in North America, especially those born after World War II, are more likely than older cohorts to engage in heavy episodic drinking and develop alcohol disorders, but this cohort effect is not found in Australia and western Europe. Cross-nationally, substantial evidence indicates that women in younger cohorts are at especially high risk for heavy episodic drinking and alcohol disorders.

DISCUSSION

Younger birth cohorts in North America and Europe are engaging in more episodic and problem drinking. The gender gap in alcohol problems is narrowing in many countries, suggesting shifting social norms surrounding gender and alcohol consumption. These trends suggest that public health efforts to specifically target heavy drinking in women are necessary.

Nicotine dependence, abuse and craving: dimensionality in an Israeli sample

AIMS

Evidence-based changes planned for Diagnostic and Statistical Manual 5th edition (DSM-5) substance use disorders (SUDs) include combining dependence and three of the abuse criteria into one disorder and adding a criterion indicating craving. Because DSM-IV did not include a category for nicotine abuse, little empirical support is available for aligning the nicotine use disorder criteria with the DSM-5 criteria for other SUDs.

DESIGN

Latent variable analyses, bootstrap tests and likelihood ratio tests were used to explore the unidimensionality, psychometric properties and information of the nicotine criteria.

SETTING AND PARTICIPANTS

A sample of household residents selected from the Israeli population register yielded 727 life-time cigarette smokers.

MEASUREMENTS

DSM-IV nicotine dependence criteria and proposed abuse and craving criteria, assessed with a structured interview.

FINDINGS

Three abuse criteria (hazardous use, social/interpersonal problems and neglect roles) were prevalent among smokers, formed a unidimensional latent trait with nicotine dependence criteria, were intermixed with dependence criteria across the severity spectrum and significantly increased the diagnostic information over the dependence-only model. A craving criterion was shown to fit well with the other criteria.

CONCLUSION

Similar to findings from research on other substances, nicotine dependence, abuse and craving criteria appear to derive from a common underlying dimension. The results support alignment of nicotine criteria with those for alcohol and drug use disorders in Diagnostic and Statistical Manual 5th edition.

Community-level determinants of tobacco use disparities in lesbian, gay, and bisexual youth: results from a population-based study

OBJECTIVE

To determine whether characteristics of the social environment surrounding lesbian, gay, and bisexual (LGB) youth contribute to their rates of tobacco use after controlling for established community-level risk factors.

DESIGN

Cross-sectional.

SETTING

Population-based study of youth.

PARTICIPANTS

A total of 31,852 eleventh-grade students (1413 LGB individuals [4.44%]) in Oregon completed the Oregon Healthy Teens survey in 2006-2008.

MAIN EXPOSURES

We created a composite index of the social environment in 34 Oregon counties. This measure included the proportion of same-sex couples, the presence of gay-straight alliances in schools, and school policies (nondiscrimination and antibullying) that specifically protected LGB students.

MAIN OUTCOME MEASURES

Any tobacco use in the past 30 days.

RESULTS

A more supportive social environment for LGB youth was significantly associated with reduced tobacco use (odds ratio, 0.92; 95% confidence interval, 0.90-0.94). This effect remained robust after controlling for sociodemographic variables and multiple community-level risk factors for tobacco use, including median county-level income, exposure to cigarette advertisements, exposure to teacher and peer smoking in schools, and school smoking rules.

CONCLUSION

This study documents an association between an objective measure of the social environment and sexual orientation-related disparities in tobacco use. These results highlight the need for structural-level interventions that reduce smoking behaviors in LGB youth.

An invariant dimensional liability model of gender differences in mental disorder prevalence: evidence from a national sample

Epidemiological studies of categorical mental disorders consistently report that gender differences exist in many disorder prevalence rates and that disorders are often comorbid. Can a dimensional multivariate liability model be developed to clarify how gender impacts diverse, comorbid mental disorders? We pursued this possibility in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; N = 43,093). Gender differences in prevalence were systematic such that women showed higher rates of mood and anxiety disorders, and men showed higher rates of antisocial personality and substance use disorders. We next investigated patterns of disorder comorbidity and found that a dimensional internalizing-externalizing liability model fit the data well, where internalizing is characterized by mood and anxiety disorders, and externalizing is characterized by antisocial personality and substance use disorders. This model was gender invariant, indicating that observed gender differences in prevalence rates originate from women and men's different average standings on latent internalizing and externalizing liability dimensions. As hypothesized, women showed a higher mean level of internalizing, while men showed a higher mean level of externalizing. We discuss implications of these findings for understanding gender differences in psychopathology and for classification and intervention.

Borderline personality disorder co-morbidity: relationship to the internalizing-externalizing structure of common mental disorders

BACKGROUND

Borderline personality disorder (BPD) shows high levels of co-morbidity with an array of psychiatric disorders. The meaning and causes of this co-morbidity are not fully understood. Our objective was to investigate and clarify the complex co-morbidity of BPD by integrating it into the structure of common mental disorders.

METHOD

We conducted exploratory and confirmatory factor analyses on diagnostic interview data from a representative US population-based sample of 34 653 civilian, non-institutionalized individuals aged ≥18 years. We modeled the structure of lifetime DSM-IV diagnoses of BPD and antisocial personality disorder (ASPD), major depressive disorder, dysthymic disorder, panic disorder with agoraphobia, social phobia, specific phobia, generalized anxiety disorder, post-traumatic stress disorder, alcohol dependence, nicotine dependence, marijuana dependence, and any other drug dependence.

RESULTS

In both women and men, the internalizing-externalizing structure of common mental disorders captured the co-morbidity among all disorders including BPD. Although BPD was unidimensional in terms of its symptoms, BPD as a disorder showed associations with both the distress subfactor of the internalizing dimension and the externalizing dimension.

CONCLUSIONS

The complex patterns of co-morbidity observed with BPD represent connections to other disorders at the level of latent internalizing and externalizing dimensions. BPD is meaningfully connected with liabilities shared with common mental disorders, and these liability dimensions provide a beneficial focus for understanding the co-morbidity, etiology and treatment of BPD.

Suicidal ideation and suicide attempts among Hispanic subgroups in the United States: 1991-1992 and 2001-2002

OBJECTIVE

To compare the prevalence of suicidal ideation/attempts among Hispanic subgroups in the US in 1991-1992 and 2001-2002, and identify high-risk groups.

METHOD

Data were drawn from the 1991-1992 National Longitudinal Alcohol Epidemiologic Survey (NLAES, n = 42,862) and the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC, n = 43,093), two nationally representative surveys of individuals aged 18 years and older.

RESULTS

1) Puerto Ricans are the Hispanic ethnic subgroup with the highest rates of suicide attempts; 2) 45- to 64-year-old Puerto Rican women are a high-risk group for suicide attempts; 3) Over the 10 year period between the two surveys, the lifetime prevalence of suicide attempts significantly increased among 18- to 24-year-old Puerto Rican women and Cuban men, and among 45- to 64-year-old Puerto Rican men.

CONCLUSION

Hispanics in the US are not a homogeneous group. We identify high-risk groups among Hispanics. Specific interventions for subgroups of Hispanics at high risk for suicidal behaviors may be required.

Birth-cohort trends in lifetime and past-year prescription opioid-use disorder resulting from nonmedical use: results from two national surveys

OBJECTIVE

This study aims to test whether recent increases in the reported prevalence of opioid-use disorder in the United States occurred across all age groups (period effect), consistently only among younger age groups (age effect), or varied according to year of birth (cohort effects).

METHOD

Joint analysis of data from the 1991-1992 National Longitudinal Alcohol Epidemiologic Survey (NLAES) and the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), focusing on individuals ages 18-57, grouped by 10-year age intervals. Sample sizes for the present analyses were 30,846 for the NLAES and 31,397 for the NESARC. Prevalence of lifetime and past-year prescription opioid-use disorder resulting from nonmedical use (abuse and dependence) was examined.

RESULTS

Within birth cohorts, prevalence of lifetime prescription opioid-use disorder increased during the 10 years between surveys, indicating the importance of age effects. In addition, lifetime and past-year prevalence of prescription opioid-use disorder was higher among more recent birth cohorts as compared with earlier birth cohorts, indicating the importance of cohort effects. Consistent with a period effect, cross-cohort comparisons showed that risk for prescription opioid-use disorder has increased for all individuals regardless of their birth cohort membership from the NLAES to the NESARC survey.

CONCLUSIONS

Findings suggest that more problems (abuse and dependence) may emerge as prescription opioid users get older and that more recent birth cohorts are at higher risk for prescription opioid problems.

Stress, coping, and depression: testing a new hypothesis in a prospectively studied general population sample of U.S.-born Whites and Blacks

The scarcity of empirically supported explanations for the Black/White prevalence difference in depression in the U.S. is a conspicuous gap in the literature. Recent evidence suggests that the paradoxical observation of decreased risk of depression but elevated rates of physical illness among Blacks in the U.S. compared with Whites may be accounted for by the use of coping behaviors (e.g., alcohol and nicotine consumption, overeating) among Blacks exposed to high stress levels. Such coping behaviors may mitigate deleterious effects of stressful exposures on mental health while increasing the risk of physical ailments. The racial patterning in mental and physical health outcomes could therefore be explained by this mechanism if a) these behaviors were more prevalent among Blacks than Whites and/or b) the effect of these behavioral responses to stress was differential by race. The present study challenges this hypothesis using longitudinal, nationally-representative data with comprehensive DSM-IV diagnoses. Data are drawn from 34,653 individuals sampled in Waves 1 (2001-2002) and 2 (2004-2005) as part of the US National Epidemiologic Survey on Alcohol and Related Conditions. Results showed that a) Blacks were less likely to engage in alcohol or nicotine consumption at low, moderate, and high levels of stress compared to Whites, and b) there was a significant three-way interaction between race, stress, and coping behavior for BMI only (F = 2.11, df = 12, p = 0.03), but, contrary to the hypothesis, elevated BMI was protective against depression in Blacks at low, not high, levels of stress. Further, engagement in unhealthy behaviors, especially at pathological levels, did not protect against depression in Blacks or in Whites. In sum, the impact of stress and coping processes on depression does not appear to operate differently in Blacks versus Whites. Further research testing innovative hypotheses that would explain the difference in Black/White depression prevalence is warranted.

Alcohol craving and the dimensionality of alcohol disorders

BACKGROUND

ICD-10 includes a craving criterion for alcohol dependence while DSM-IV does not. Little is known about whether craving fits with or improves the DSM-IV criteria set for alcohol-use disorders.

METHOD

Data were derived from current drinkers (n=18 352) in the 1991-1992 National Longitudinal Alcohol Epidemiologic Survey (NLAES), a nationally representative survey of US adults >17 years of age. The Alcohol Use Disorder and Associated Disabilities Interview Schedule was used to assess the eleven DSM-IV dependence and abuse criteria, and alcohol craving. Exploratory factor, item response theory, and regression analyses were used to evaluate the psychometric properties and concurrent validity of DSM-based alcohol disorder criteria with the addition of alcohol craving.

RESULTS

The past 12-month prevalence of craving was 1.3%. Craving formed part of a unidimensional latent variable that included existing DSM-IV criteria. Craving demonstrated high severity on the alcohol-use disorder continuum, resulting in an improved dimensional model with greater discriminatory ability compared with current DSM-IV criteria. Correlates of the diagnosis did not change with the addition of craving, and past 12-month craving was associated with prior alcohol dependence, depression, and earlier age of alcohol disorder onset among those with current DSM-IV alcohol dependence.

CONCLUSIONS

The addition of craving to the existing DSM-IV criteria yields a continuous measure that better differentiates individuals with and without alcohol problems along the alcohol-use disorder continuum. Few individuals are newly diagnosed with alcohol dependence given the addition of craving, indicating construct validity but redundancy with existing criteria.

The protective effects of social/contextual factors on psychiatric morbidity in LGB populations

BACKGROUND

Lesbian, gay and bisexual (LGB) populations evidence higher rates of psychiatric disorders than heterosexuals, but most LGB individuals do not have mental-health problems. The present study examined risk modifiers at the social/contextual level that may protect LGB individuals from the development of psychiatric disorders.

METHODS

Data are drawn from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (N = 34,653), a nationally representative study of non-institutionalized US adults. Risk variables included social isolation and economic adversity. High state-level concentration of same-sex couples, obtained from the US Census, was examined as a protective factor.

RESULTS

The past-year prevalence of major depression and generalized anxiety disorder was lower among LGB respondents living in states with higher concentrations of same-sex couples, compared with LGB respondents in states with lower concentrations. Additionally, the increased risk for mood and anxiety disorders among LGB individuals exposed to economic adversity and social isolation was evident only in states with low concentrations of same-sex couples. These interactions between the risk and protective factors were not found among heterosexuals, suggesting specificity of the effects to LGB individuals. Results were not attenuated after controlling for socio-demographic factors, state-level income inequality, state-level policies targeting LGBs and state-level attitudes towards LGB-relevant issues.

CONCLUSIONS

These results provide evidence for the protective effect of social/contextual influences on the prevalence of psychiatric disorders in LGB individuals. Measures of the social environment should be incorporated into future research on the mental health of LGB populations.

Levels of risk: maternal-, middle childhood-, and neighborhood-level predictors of adolescent disinhibitory behaviors from a longitudinal birth cohort in the United States

OBJECTIVE: Disruptive behavior in adolescence may indicate a broad vulnerability to disinhibition, which begins in childhood and culminates in adult externalizing psychopathology. We utilized prospective birth cohort data to assess childhood predictors of adolescent disinhibition. We also examined the effect of pre-adolescent fluctuation in cognitive ability. METHODS: Data were drawn from the Child Health and Development Study cohort, born 1961-1963; we used the subsample who participated in follow-up through adolescence (n=1752). Six indicators of behavioral disinhibition (BD), reported in adolescence, were analyzed as a count outcome. Predictor variables were drawn from several waves of data collection and included individual-, maternal-, and neighborhood-level measures. Cognitive ability was assessed with the Peabody Picture Vocabulary Test at two time points. Neighborhood characteristics were assessed using census data from 1970. RESULTS: Number of BD indicators was predicted by maternal characteristics at prenatal assessment (maternal age and alcohol consumption) and age-10 assessment (maternal smoking, education, and separation from father). Characteristics of the child that predicted BD included birth order and conduct problems in middle childhood. Neighborhood poverty did not predict BD. Regardless of initial cognitive ability score, movement to a higher quartile by adolescence was associated with lower BD, while movement to a lower quartile was associated with higher BD. CONCLUSION: Risk for adolescent BD exists prenatally and extends through middle childhood. Change in cognitive ability during pre-adolescence emerged as a potentially important factor that merits further investigation. A greater focus on the life course can aid in comprehensively understanding disruptive behavior emergence in adolescence.

Stress, coping, and depression: testing a new hypothesis in a prospectively studied general population sample of U.S.-born Whites and Blacks

The scarcity of empirically supported explanations for the Black/White prevalence difference in depression in the U.S. is a conspicuous gap in the literature. Recent evidence suggests that the paradoxical observation of decreased risk of depression but elevated rates of physical illness among Blacks in the U.S. compared with Whites may be accounted for by the use of coping behaviors (e.g., alcohol and nicotine consumption, overeating) among Blacks exposed to high stress levels. Such coping behaviors may mitigate deleterious effects of stressful exposures on mental health while increasing the risk of physical ailments. The racial patterning in mental and physical health outcomes could therefore be explained by this mechanism if a) these behaviors were more prevalent among Blacks than Whites and/or b) the effect of these behavioral responses to stress was differential by race. The present study challenges this hypothesis using longitudinal, nationally-representative data with comprehensive DSM-IV diagnoses. Data are drawn from 34,653 individuals sampled in Waves 1 (2001-2002) and 2 (2004-2005) as part of the US National Epidemiologic Survey on Alcohol and Related Conditions. Results showed that a) Blacks were less likely to engage in alcohol or nicotine consumption at low, moderate, and high levels of stress compared to Whites, and b) there was a significant three-way interaction between race, stress, and coping behavior for BMI only (F = 2.11, df = 12, p = 0.03), but, contrary to the hypothesis, elevated BMI was protective against depression in Blacks at low, not high, levels of stress. Further, engagement in unhealthy behaviors, especially at pathological levels, did not protect against depression in Blacks or in Whites. In sum, the impact of stress and coping processes on depression does not appear to operate differently in Blacks versus Whites. Further research testing innovative hypotheses that would explain the difference in Black/White depression prevalence is warranted.

Stigma and treatment for alcohol disorders in the United States

Among a nationally representative sample of adults with an alcohol use disorder, the authors tested whether perceived stigmatization of alcoholism was associated with a lower likelihood of receiving alcohol-related services. Data were drawn from a face-to-face epidemiologic survey of 34,653 adults interviewed in 2004-2005 who were aged 20 years or older and residing in households and group quarters in the United States. Alcohol abuse/dependence was diagnosed by using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, version (AUDADIS-IV). The stigma measure used was the Perceived Devaluation-Discrimination Scale. The main outcome was lifetime intervention including professional services and 12-step groups for alcohol disorders. Individuals with a lifetime diagnosis of an alcohol use disorder were less likely to utilize alcohol services if they perceived higher stigma toward individuals with alcohol disorders (odds ratio = 0.37, 95% confidence interval: 0.18, 0.76). Higher perceived stigma was associated with male gender (β = -0.75; P < 0.01), nonwhite compared with non-Hispanic white race/ethnicity, lower income (β = 1.0; P < 0.01), education (β = 1.48; P < 0.01), and being previously married (β = 0.47; P = 0.02). Individuals reporting close contact with an alcohol-disordered individual (e.g., relative with an alcohol problem) reported lower perceived stigma (β = -1.70; P < 0.01). A link between highly stigmatized views of alcoholism and lack of services suggests that stigma reduction should be integrated into public health efforts to promote alcohol treatment.

A multiphase method for estimating cohort effects in age-period contingency table data

PURPOSE

Understanding the effects of age, period, and cohort on disease morbidity and mortality may help identify etiological factors and inform prevention programs. We illustrate a three-phase method that conceptualizes the cohort effect as a partial interaction between age and period. As an example of application, we analyze homicide mortality data for males in the United States from 1935 through 2004.

METHODS

The three-phased method begins with graphical inspection; second, a median polish is used to remove the log-additive components of age and period effects; third, a linear regression of residuals from the median polish is modeled to quantify the relative magnitude of the cohort effect.

RESULTS

Individuals born after 1960 have a significantly increased rate of homicide relative to those born between 1920 and 1924. After removal of the log-additive effects of age and period, the estimated homicide rate for men born between 1980 and 1984 is more than twice the rate for men born between 1920 and 1924 (rate ratio, 2.11; 95% confidence interval, 1.98-2.25).

CONCLUSION

The three-phase method presented herein offers several advantages, the foremost being an alternative conceptualization of the cohort effect not as an independent component of age and period effects, but as a partial interaction. In addition, the strengths of the method include computational simplicity, interpretability, and reliability.

The role of a prescription in anxiety medication use, abuse, and dependence

OBJECTIVE

Prescriptions for anxiety medications have increased substantially in recent years. Individuals with anxiety disorders are at risk of nonmedical use of these medications, but information about whether this risk is elevated among patients with a prescription for such medications is lacking. The authors compared risk of nonmedical use in individuals in a national sample with and without a prescription for anxiety medication and identified characteristics associated with nonmedical use.

METHOD

Data were drawn from face-to-face surveys of 34,653 adult participants in the National Epidemiologic Survey on Alcohol and Related Conditions. The risk of nonmedical use of prescription anxiety medication and associated drug use disorders was computed for individuals who had or had not ever received a prescription for anxiety medication; among those who had received a prescription, characteristics associated with nonmedical use were analyzed.

RESULTS

Prescription of anxiety medication was associated with lifetime and past-year nonmedical use (odds ratios, 1.6 and 1.9, respectively) and lifetime DSM-IV abuse or dependence (odds ratio, 2.6). Among respondents who received a prescription (N=4,294), nonmedical use was associated with male sex, younger age, white race, history of use of illicit drugs, history of other drug use disorders, and history of illegal behaviors.

CONCLUSIONS

These results indicate that prescription for anxiety medications is associated with nonmedical use of these medications, although the direction of causality cannot be determined in this study. Although anxiety medications have clinical utility, greater clinical attention should be given to the potential for their abuse among patients at particular risk.

Telescoping and gender differences in alcohol dependence: new evidence from two national surveys

OBJECTIVE

The course of alcohol disorders in women is often described as "telescoped" compared to that in men, with a later age at initiation of alcohol use but shorter times from use to dependence and treatment. This study examined evidence for such a telescoping effect in the general population and tested birth cohort effects for gender differences.

METHOD

Data from two U.S. national surveys conducted 10 years apart (1991-1992 and 2001-2002) using the same diagnostic instrument (the Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV) were used to analyze five birth cohorts. Age at initiation of alcohol use, time from first use to dependence, and time from dependence to first treatment were analyzed. Interaction terms (cohort by gender; cohort by gender by time) were tested in Cox proportional hazards models.

RESULTS

Little evidence was found for a telescoping effect in women. For alcohol use and dependence, cohort and gender interacted, which suggests that gender differences are diminished in more recent cohorts. A three-way interaction of cohort, gender, and time was significant for time from first use to dependence, suggesting that men have a shorter time to dependence, especially in younger cohorts.

CONCLUSIONS

A telescoping effect is not evident in the general population. Gender differences in the overall hazard of alcohol use and dependence are decreasing in more recent cohorts, while gender differences in time from first use to dependence are increasing. These findings challenge the commonly held notion of a gender-specific course of alcohol disorders and suggest the need for a greater clinical focus on problem drinking in women and further research on accelerated time to dependence in men.

Responses to discrimination and psychiatric disorders among Black, Hispanic, female, and lesbian, gay, and bisexual individuals

OBJECTIVES

We examined associations between perceived discrimination due to race/ethnicity, sexual orientation, or gender; responses to discrimination experiences; and psychiatric disorders.

METHODS

The sample included respondents in the 2004-2005 National Epidemiologic Survey on Alcohol and Related Conditions (n = 34 653). We analyzed the associations between self-reported past-year discrimination and past-year psychiatric disorders as assessed with structured diagnostic interviews among Black (n = 6587); Hispanic (n = 6359); lesbian, gay, and bisexual (LGB; n = 577); and female (n = 20 089) respondents.

RESULTS

Black respondents reported the highest levels of past-year discrimination, followed by LGB, Hispanic, and female respondents. Across groups, discrimination was associated with 12-month mood (odds ratio [ORs] = 2.1-3.1), anxiety (ORs = 1.8-3.3), and substance use (ORs = 1.6-3.5) disorders. Respondents who reported not accepting discrimination and not discussing it with others had higher odds of psychiatric disorders (ORs = 2.9-3.9) than did those who did not accept discrimination but did discuss it with others. Black respondents and women who accepted discrimination and did not talk about it with others had elevated rates of mood and anxiety disorders, respectively.

CONCLUSIONS

Psychiatric disorders are more prevalent among individuals reporting past-year discrimination experiences. Certain responses to discrimination, particularly not disclosing it, are associated with psychiatric morbidity.

Suicidal ideation and suicide attempts in the United States: 1991-1992 and 2001-2002

The aim of the study is to compare the prevalence of suicidal ideation and attempts in the United States in 1991-1992 and 2001-2002, and identify sociodemographic groups at increased risk for suicidal ideation and attempts. Data were drawn from the National Institute on Alcohol Abuse and Alcoholism 1991-1992 National Longitudinal Alcohol Epidemiologic Survey (n=42,862) and the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (n=43,093), two nationally representative household surveys of non-institutionalized civilians aged 18 years and older, residing in the United States. The lifetime prevalence of suicide attempts remained unchanged in the United States between 1991-1992 and 2001-2002. Specific groups, namely 18- to 24-year-old white and black women, 25- to 44-year-old white women and 45- to 64-year-old Native American men were identified as being at high risk for suicide attempts. Despite prevention and treatment efforts, the lifetime prevalence of suicide attempts remains unchanged. Given the morbidity and mortality associated with suicide attempts, urgent action is needed to decrease the prevalence of suicide attempts in the United States.

What is a cohort effect? Comparison of three statistical methods for modeling cohort effects in obesity prevalence in the United States, 1971-2006

Analysts often use different conceptual definitions of a cohort effect, and therefore different statistical methods, which lead to differing empirical results. A definition often used in sociology assumes that cohorts have unique characteristics confounded by age and period effects, whereas epidemiologists often conceive that period and age effects interact to produce cohort effects. The present study aims to illustrate these differences by estimating age, period, and cohort (APC) effects on obesity prevalence in the U.S. from 1971 to 2006 using both conceptual approaches. Data were drawn from seven cross-sectional waves of the National Health and Nutrition Examination Survey. Obesity was defined as BMI >or=30 for adults and >or=95th percentile for children under the age of 20. APC effects were estimated using the classic constraint-based method (first-order effects estimated and interpreted), the Holford method (first-order effects estimated but second-order effects interpreted), and median polish method (second-order effects are estimated and interpreted). Results indicated that all methods report significant age and period effects, with lower obesity prevalence in early life as well as increasing prevalence in successive surveys. Positive cohort effects for more recently born cohorts emerged based on the constraint-based model; when cohort effects were considered second-order estimates, no significant effects emerged. First-order estimates of age-period-cohort effects are often criticized because of their reliance on arbitrary constraints, but may be conceptually meaningful for sociological research questions. Second-order estimates are statistically estimable and produce conceptually meaningful results for epidemiological research questions. Age-period-cohort analysts should explicitly state the definition of a cohort effect under consideration. Our analyses suggest that the prevalence of obesity in the U.S. in the latter part of the 20th century rose across all birth cohorts, in the manner expected based on estimated age and period effects. As such, the absence or presence of cohort effects depends on the conceptual definition and therefore statistical method used.

The impact of institutional discrimination on psychiatric disorders in lesbian, gay, and bisexual populations: a prospective study

OBJECTIVES

We examined the relation between living in states that instituted bans on same-sex marriage during the 2004 and 2005 elections and the prevalence of psychiatric morbidity among lesbian, gay, and bisexual (LGB) populations.

METHODS

We used data from wave 1 (2001-2002) and wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (N = 34,653), a longitudinal, nationally representative study of noninstitutionalized US adults.

RESULTS

Psychiatric disorders defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, increased significantly between waves 1 and 2 among LGB respondents living in states that banned gay marriage for the following outcomes: any mood disorder (36.6% increase), generalized anxiety disorder (248.2% increase), any alcohol use disorder (41.9% increase), and psychiatric comorbidity (36.3% increase). These psychiatric disorders did not increase significantly among LGB respondents living in states without constitutional amendments. Additionally, we found no evidence for increases of the same magnitude among heterosexuals living in states with constitutional amendments.

CONCLUSIONS

Living in states with discriminatory policies may have pernicious consequences for the mental health of LGB populations. These findings lend scientific support to recent efforts to overturn these policies.

Associations between perceived weight discrimination and the prevalence of psychiatric disorders in the general population

Despite the increased prevalence of weight discrimination, few studies have examined the association between perceived weight discrimination and the prevalence of current psychiatric disorders in the general population. This study utilized a subsample of overweight and obese individuals (N = 22,231) from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a cross-sectional nationally representative study of noninstitutionalized US adults. Perceived weight discrimination is associated with substantial psychiatric morbidity and comorbidity. These results remained significant after adjusting for a potential confound, perceived stress. Moreover, social support did not buffer against the adverse effects of perceived weight discrimination on mental health. Controlling for BMI did not diminish the associations, indicating that perceived weight discrimination is potentially harmful to mental health regardless of weight. These results highlight the urgent need for a multifaceted approach to address this important public health issue, including interventions to assist overweight individuals in coping with the mental health sequelae of perceived weight discrimination.

State-level policies and psychiatric morbidity in lesbian, gay, and bisexual populations

OBJECTIVES

We investigated the modifying effect of state-level policies on the association between lesbian, gay, or bisexual status and the prevalence of psychiatric disorders.

METHODS

Data were from wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative study of noninstitutionalized US adults (N=34,653). States were coded for policies extending protections against hate crimes and employment discrimination based on sexual orientation.

RESULTS

Compared with living in states with policies extending protections, living in states without these policies predicted a significantly stronger association between lesbian, gay, or bisexual status and psychiatric disorders in the past 12 months, including generalized anxiety disorder (F=3.87; df=2; P=.02), post-traumatic stress disorder (F=3.42; df=2; P=.04), and dysthymia (F=5.20; df=2; P=.02). Living in states with policies that did not extend protections also predicted a stronger relation between lesbian, gay, or bisexual status and psychiatric comorbidity (F=2.47; df=2; P=.04).

CONCLUSIONS

State-level protective policies modify the effect of lesbian, gay, or bisexual status on psychiatric disorders. Policies that reduce discrimination against gays and lesbians are urgently needed to protect the health and well-being of this population.

Pathways between nonmedical opioid use/dependence and psychiatric disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions

BACKGROUND

While nonmedical use of opioids and psychiatric disorders are prevalent in the population, little is known about the temporal ordering between nonmedical opioid use and dependence and psychiatric disorders.

METHOD

Data were gathered in a face-to-face survey of the United States conducted in the 2001-2002 (NESARC wave 1). Participants were household and group quarters residents aged 18 years and older (n=43,093). Cox proportional hazards models with time-dependent covariates were used to investigate potential pathways between lifetime nonmedical opioid use/dependence and psychiatric disorders.

RESULTS

Preexisting psychiatric disorders (mood disorders, major depressive disorder, bipolar I disorder, anxiety disorders, panic and generalized anxiety disorders) were associated with an increased risk of nonmedical opioid use, with hazard ratios ranging from 2.2[95% CI=1.6-3.1] (any anxiety disorder) to 3.1[95% CI=2.4-2.4] (bipolar I disorder). Preexisting nonmedical opioid use was associated with an increased risk of onset of psychiatric disorders, with hazard ratios ranging from 2.8[95% CI=2.2-3.6] (generalized anxiety disorder) to 3.6[95% CI=2.6-4.9] (bipolar I disorder), adjusted for demographics and other illegal drug use. Nonmedical use of opioids led to the development of dependence more often among individuals with preexisting psychiatric disorders, hazard ratios were particularly strong for generalized anxiety disorder (HR=10.8, 95% CI=4.9-23.7) and bipolar I disorder (HR=9.7, 95% CI=5.4-17.3). Preexisting opioid dependence resulting from nonmedical opioid use was associated with an increased risk of onset of psychiatric disorders, with hazard ratios ranging from 4.9[95% CI=3.0-7.9] (mood disorders) to 8.5[95% CI=4.5-16.0] (panic disorder), adjusted for demographics and alcohol and/or other illegal drug dependence.

CONCLUSIONS

Our findings support a general vulnerability to nonmedical opioid use and major psychopathologies, as well as evidence for a 'self-medication' model for dependence resulting from nonmedical opioid use with bipolar disorder and generalized anxiety disorder.

Influence of a drinking quantity and frequency measure on the prevalence and demographic correlates of DSM-IV alcohol dependence

BACKGROUND

Recent research suggests that adding a quantity/frequency alcohol consumption measure to diagnoses of alcohol use disorders may improve construct validity of the diagnoses for Diagnostic and Statistical Manual of Mental and Behavior Disorders (DSM-V). This study explores the epidemiological impact of including weekly at-risk drinking (WAD) in the DMS-IV diagnostic definition of alcohol dependence via 3 hypothetical reformulations of the current criteria.

METHODS

The sample was the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample with 43,093 adults aged >18 in the U.S interviewed with the Alcohol Use Disorder and Associated Disabilities Interview Schedule IV. The current (DSM-IV) definition of alcohol dependence was compared with 4 hypothetical alcohol dependence reformulations that included WAD: (1) WAD added as an eighth criteria; (2) WAD required for a diagnosis; (3) adding abuse and dependence criteria together, and including WAD with a 3 of 12 symptom threshold; (4) adding abuse and dependence criteria together, and including WAD with a 5 of 12 symptom threshold.

RESULTS

The inclusion of at-risk drinking as an eighth criterion of alcohol dependence has a minimal impact on the sociodemographic correlates of alcohol dependence but substantially increases the prevalence of dependence (from 3.8% to 5.0%). At-risk drinking as a required criterion or as part of a diagnosis that combines abuse with dependence criteria with a higher threshold (5+ criteria) decreases prevalence and has a larger impact on sociodemographic correlates. Blacks, Hispanics, and women are less likely to be included in diagnostic reformulations that include WAD, whereas individuals with low-income and education are more likely to remain diagnosed.

CONCLUSIONS

Including WAD as either a requirement of diagnosis or as an additional criterion would have a large impact on the prevalence of alcohol dependence in the general population. The inclusion of a quantity/frequency requirement may eliminate false positives from studies of alcohol disorder etiology and improve phenotype definition for genetic association studies by reducing heterogeneity in the diagnosis, but may also reduce eligibility for treatment services among women and racial/ethnic minorities compared.

Adverse childhood events and lifetime alcohol dependence

OBJECTIVES

We sought to study the association between adverse events occurring in childhood and adolescence and lifetime alcohol dependence in a representative sample of American adults.

METHODS

With data from the National Epidemiologic Survey on Alcohol and Related Conditions, we conducted logistic regression multivariate analyses to examine the impact of adverse events occurring in childhood (aged < 18 years) on the lifetime prevalence of alcohol dependence. We controlled for age at drinking onset, binge drinking, alcoholism in parents and grandparents of respondents, and demographic characteristics.

RESULTS

Adverse childhood events were associated with familial alcoholism and with early and binge drinking, and therefore, we controlled for these potential confounders. Experiencing 2 or more adverse childhood events, compared with none, significantly increased the risk for alcohol dependence, even after we controlled for sociodemographic variables and disorder-specific potential confounders not considered in the extant literature (adjusted odds ratio = 1.37; 95% confidence interval = 1.06, 1.77).

CONCLUSIONS

Individuals who experienced 2 or more adverse childhood events are at increased risk for lifetime alcohol dependence. A better understanding of the factors underlying the risk for alcohol dependence is important for developing better prevention and early intervention measures.

Childhood or adolescent parental divorce/separation, parental history of alcohol problems, and offspring lifetime alcohol dependence

BACKGROUND

This study examined whether the experiences of childhood or adolescent parental divorce/separation and parental alcohol problems affected the likelihood of offspring DSM-IV lifetime alcohol dependence, controlling for parental history of drug, depression, and antisocial behavior problems.

METHOD

Data were drawn from the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a nationally representative United States survey of 43,093 civilian non-institutionalized participants aged 18 and older, interviewed in person. Logistic regression models were used to calculate the main and interaction effects of childhood or adolescent parental divorce/separation and parental history of alcohol problems on offspring lifetime alcohol dependence, after adjusting for parental history of drug, depression, and antisocial behavior problems.

RESULTS

Childhood or adolescent parental divorce/separation and parental history of alcohol problems were significantly related to offspring lifetime alcohol dependence, after adjusting for parental history of drug, depression, and antisocial behavior problems. Experiencing parental divorce/separation during childhood, even in the absence of parental history of alcohol problems, remained a significant predictor of lifetime alcohol dependence. Experiencing both childhood or adolescent parental divorce/separation and parental alcohol problems had a significantly stronger impact on the risk for DSM-IV alcohol dependence than the risk incurred by either parental risk factor alone.

CONCLUSIONS

Further research is needed to better identify the factors that increase the risk for lifetime alcohol dependence among those who experience childhood or adolescent parental divorce/separation.

Changes in cigarette use and nicotine dependence in the United States: evidence from the 2001-2002 wave of the national epidemiologic survey of alcoholism and related conditions

OBJECTIVES

We examined the roles of gender and poverty in cigarette use and nicotine dependence among adults in the United States.

METHODS

Our data were drawn from the 2001-2002 National Epidemiological Survey of Alcoholism and Related Conditions, a nationally representative sample of US adults 18 years and older.

RESULTS

The overall rate of cigarette use declined between 1964 and 2002. Nicotine dependence does not appear to have declined overall, and there is evidence that nicotine dependence has increased among women in recent cohorts. The odds of nicotine dependence among cigarette users appear to have increased significantly in recent cohorts.

CONCLUSIONS

Despite recent declines in cigarette use, the prevalence of nicotine dependence has increased among some groups and has remained steady overall, which may be hampering public health initiatives to reduce cigarette use. Efforts to study or curb cigarette use should therefore take nicotine dependence into account.

Cannabis withdrawal in the United States: results from NESARC

OBJECTIVE

Although cannabis is the most widely abused illicit drug, little is known about the prevalence of cannabis withdrawal and its factor structure, clinical validity, and psychiatric correlates in the general population.

METHOD

National Epidemiologic Survey on Alcohol and Related Conditions participants were assessed, in 2001-2002, with structured in-person interviews covering substance history, DSM-IV Axis I and II disorders, and withdrawal symptoms after cessation of use. Of these, 2613 had been frequent cannabis users (> or = 3 times/week), and a "cannabis-only" subset (N = 1119) never binge-drank or used other drugs > or = 3 times/week.

RESULTS

In the full sample and subset, 44.3% (SE = 1.19) and 44.2% (SE = 1.75), respectively, experienced > or = 2 cannabis withdrawal symptoms, while 34.4% (SE = 1.21) and 34.1% (SE = 1.76), respectively, experienced > or = 3 symptoms. The symptoms formed 2 factors, one characterized by weakness, hypersomnia, and psychomotor retardation and the second by anxiety, restlessness, depression, and insomnia. Both symptom types were associated with significant distress/impairment (p < .01), substance use to relieve/avoid cannabis withdrawal symptoms (p <.01), and quantity of cannabis use (among the cannabis-only users p < .05). Panic (p < .01) and personality (p > .01) disorders were associated with anxiety symptoms in both samples, family history of drug problems was associated with weakness symptoms in the subset (p = .01), and depression was associated with both sets of symptoms in the subset (p < or = .05).

CONCLUSION

Cannabis withdrawal was prevalent and clinically significant among a representative sample of frequent cannabis users. Similar results in the subset without polysubstance abuse confirmed the specificity of symptoms to cannabis. Cannabis withdrawal should be added to DSM-V, and the etiology and treatment implications of cannabis withdrawal symptoms should be investigated.

Nicotine dependence and mental disorders among adults in the USA: evaluating the role of the mode of administration

BACKGROUND

To investigate the association between nicotine dependence (ND), by cigarette smoking and use of smokeless tobacco (UST), and mental disorders.

METHOD

Face-to-face surveys (n=43 093) were conducted in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Nicotine use, ND, and mental disorders were assessed using DSM-IV criteria.

RESULTS

UST-ND was associated with a significantly increased likelihood of any anxiety disorder, specific phobia, alcohol abuse and dependence. Consistent with previous findings, cigarette smoking-ND was associated with an increased likelihood of all mental disorders examined. Among those without ND, cigarette smoking was specifically associated with panic attacks and panic disorder; non-dependent UST was not associated with mental disorders.

CONCLUSIONS

Our findings suggest that the association between ND and mental disorders is relatively specific to the mode of nicotine administration. Among those who are nicotine dependent, cigarette use is associated with most major psychiatric disorders, whereas UST is associated with dysthymia and specific phobia. Among those who use tobacco but are not nicotine dependent, cigarette use is associated with dysthymia and panic disorder; UST is not associated with any major mood or anxiety disorders. The link between mental disorders and nicotine is complex, and is associated primarily with dependence, and not with non-dependent use.

Past 12-month and lifetime comorbidity and poly-drug use of ecstasy users among young adults in the United States: results from the National Epidemiologic Survey on Alcohol and Related Conditions

BACKGROUND

Ecstasy use is prevalent among young people and often co-occurs with other drug use, but little is known about the past 12-month and lifetime psychiatric comorbidity and specific additional drug abuse among young adult ecstasy users in the general population. To provide this information, we compared current ecstasy users to former users, other illicit drug users, and non-illicit drug users.

METHOD

Data were gathered in a face-to-face survey of the United States conducted in the 2001-2002 (NESARC). Participants were household and group quarters residents aged 18-29 years (n=8666). We measured current ecstasy use defined as any use in the past year; former ecstasy use as use prior to the past year only; other lifetime drug use included any drug other than ecstasy; lifetime non-illicit drug use as no illicit drug use. Associations were determined for nine other classes of illicit drugs, eight personality disorders, and seven mood and anxiety disorders.

RESULTS

Of current ecstasy users, 44% used >3 other classes of illicit drugs in the past year, compared to 1.6% of non-ecstasy drug users. Current ecstasy use was associated with current anxiety (OR=3.7), specifically panic disorder (OR=7.7) and specific phobia (OR=4.1), also alcohol abuse (OR=21.6) and dependence (OR=4.1) and any personality disorder (OR=5.1) compared to non-illicit drug users.

CONCLUSIONS

Results indicate important differences in comorbidities of current and former ecstasy users compared to other drug users and lifetime non-illicit drug users that may affect phenotype definitions and etiologic studies. Ecstasy use may represent a distinct population of drug users for which unique treatments may be necessary.

Service utilization differences for Axis I psychiatric and substance use disorders between white and black adults

OBJECTIVE

Although studies have shown disparities between black and white populations in service utilization for mental disorders, little information exists on whether such disparities apply equally across disorders. The objective of this study was to examine racial differences in lifetime prevalence of service utilization for mood and anxiety disorders and for alcohol and drug use disorders, with controls for predisposing, enabling, and need-for-service variables unequally distributed between racial-ethnic groups.

METHODS

Data were from a face-to-face epidemiologic survey of 32,752 non-Hispanic white or black adults ages 18 and older residing in households and group quarters in the United States. Main outcome measures were treatment for mood, anxiety, and alcohol and drug use disorders.

RESULTS

White adults were consistently more likely than black adults to have had treatment for mood disorders (odds ratio [OR]=2.16, 95% confidence interval [CI]=1.80-2.59) and anxiety disorders (OR=1.77, 95% CI=1.43-2.19) after adjustment for predisposing and enabling factors and need for service (severity of disorder). In contrast no evidence of lower service utilization for treatment of alcohol use disorders emerged among black respondents (OR=.87, 95% CI=.69-1.10). Moreover, white respondents with drug use disorders were significantly less likely than black respondents to receive treatment for a drug problem (OR=.64, 95% CI=.47-.88).

CONCLUSIONS

Differences in treatment between black and white adults depended on the specific disorder and type of treatment considered. Prevention and intervention strategies should address disorder-specific disparities in services received.

Racial/ethnic disparities in service utilization for individuals with co-occurring mental health and substance use disorders in the general population: results from the national epidemiologic survey on alcohol and related conditions

OBJECTIVE

This study sought to determine whether black/white disparities in service utilization for mental health and substance use disorders persist or are diminished among individuals with psychiatric comorbidity in the general population.

METHOD

The 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions was used to identify individuals with lifetime co-occurring substance use disorders and mood/anxiety disorders (N = 4250; whites, N = 3597; blacks, N = 653). Lifetime service utilization for problems with mood, anxiety, alcohol, and drugs was assessed.

RESULTS

Compared to whites, blacks with co-occurring mood or anxiety and substance use disorders were significantly less likely to receive services for mood or anxiety disorders, equally likely to receive services for alcohol use disorders, and more likely to receive some types of services for drug use disorders. Regardless of race/ethnicity, individuals with these co-occurring disorders were almost twice as likely to use services for mood/anxiety disorders than for substance use disorders.

CONCLUSION

Despite the fact that comorbidity generally increases the likelihood of service use, black/white disparities in service utilization among an all-comorbid sample were found, although these disparities differed by type of disorder. Further research is warranted to understand the factors underlying these differences. Prevention and intervention strategies are needed to address the specific mental health needs of blacks with co-occurring disorders, as well as the overall lack of service use for substance use disorders among individuals with co-occurring psychiatric conditions.
