Ten-year trends (1992 to 2002) in sociodemographic predictors and indicators of alcohol abuse and dependence among whites, blacks, and Hispanics in the United States

Background: The objective of this paper is to examine 10‐year trends (1992 to 2002) in the number and type of indicators of DSM‐IV abuse and dependence among whites, blacks, and Hispanics in the United States. Methods: Data are from the 1991 to 1992 National Longitudinal Alcohol Epidemiologic Survey (NLAES; n = 42,862) and the 2001 to 2002 National Epidemiologic Study on Alcohol and Related Conditions (NESARC; n = 43,093). Both surveys used multistage cluster sample procedures to select respondents 18 years of age and older from the U.S. household population. Results: Increases in the prevalence of alcohol abuse between 1992 and 2002 seem associated with a rise in the prevalence of the indicator for “hazardous use.” which usually means reports of driving after drinking. The decrease in dependence was not associated with changes in a particular indicator. In addition, both in 1992 and 2002, 12.3 to 15.4% of the men and 5.2 to 7.9% of the women were diagnostic “orphans.” These respondents reported 1 or 2 indicators of alcohol dependence as present. Conclusions: The observed trends in number and types of indicators of DSM‐IV alcohol abuse and dependence were probably triggered by a complex interplay between individuals’ volume and pattern of drinking and reactions from the drinkers’ social environment. The close association between hazardous use of alcohol and the prevalence of abuse deserves further discussion. A medical diagnostic category should not be so dependent on a criterion that may be influenced by social situations. It is necessary to understand more about diagnostic “orphans” to better design interventions to address their problems.     

Relationship between personality change and the onset and course of alcohol dependence in young adulthood

Aims To examine the reciprocal effects between the onset and course of alcohol use disorder (AUD) and normative changes in personality traits of behavioral disinhibition and negative emotionality during the transition between adolescence and young adulthood. Design Longitudinal–epidemiological study assessing AUD and personality at ages 17 and 24 years. Setting Participants were recruited from the community and took part in a day‐long, in‐person assessment. Participants Male (n = 1161) and female (n = 1022) twins participating in the Minnesota Twin Family Study. Measurements The effects of onset (adolescent versus young adult) and course (persistent versus desistent) of AUD on change in personality traits of behavioral disinhibition and negative emotionality from ages 17 to 24 years. Findings Onset and course of AUD moderated personality change from ages 17 to 24 years. Adolescent onset AUD was associated with greater decreases in behavioral disinhibition. Those with an adolescent onset and persistent course failed to exhibit normative declines in negative emotionality. Desistence was associated with a ‘recovery’ towards psychological maturity in young adulthood, while persistence was associated with continued personality dysfunction. Personality traits at age 11 predicted onset and course of AUD, indicating personality differences were not due to active substance abuse. Conclusions Personality differences present prior to initiation of alcohol use increase risk for alcohol use disorder, but the course of alcohol use disorder affects the rate of personality change during emerging adulthood. Examining the reciprocal effects of personality and alcohol use disorder within a developmental context is necessary to improve understanding for theory and intervention.     

Lifetime alcohol intake and pattern of alcohol consumption in patients with alcohol-induced pancreatitis in comparison with patients with alcohol use disorder

Objective: To examine lifetime drinking patterns in men and women with alcohol-induced pancreatitis (AIP) in comparison with patients with alcoholic use disorder (AUD) without pancreatic disease.

Methods: Alcohol consumption patterns were assessed using a validated questionnaire, the Lifetime Drinking History (LDH), during an outpatient visit. Patients diagnosed with AIP were matched for gender and age (+/? 5 years) with patients with AUD in addiction treatment.

Results: A total of 45 patients with AIP (35 males, 10 females) and 45 AUD patients were included. Alcohol consumption patterns were not significantly different between males and females with AIP and those with history of acute AIP and chronic pancreatitis (CP). Alcohol consumption patterns of AIP and AUD patients were similar in terms of onset age and duration of alcohol consumption, lifetime alcohol intake and drinks per drinking day. A higher proportion of binge drinking was found among patients with AUD than those with AIP (median 1.00 vs. 0.94, p?=?.01). Males with AUD had lower onset age (15 vs. 16 years, p?=?.03), higher total amount of spirits (35520 vs. 10450 drinks, p?=?.04) and higher proportion of binge drinking (1.00 vs. 0.97, p?=?.01) than males with AIP, whereas females with AIP and AUD had similar drinking patterns.

Conclusions: Alcohol drinking patterns and lifetime drinking history was similar in patients with AIP and patients with AUD. Males with AIP had lower total amount of spirits and lower proportion of binge drinking than those with AUD, suggesting the idiosyncratic etiology of AIP.     

Trends in alcohol services utilization from 1991-1992 to 2001-2002: ethnic group differences in the U.S. population

Background: During the early 1990s in the United States, changes to the provision and financing of alcohol treatment services included reductions in inpatient treatment services and in private sector spending for treatment. We investigated trends in alcohol services utilization over the 10‐year period from 1991–1992 to 2001–2002 among U.S. whites, blacks, and Hispanics. Methods: Data come from 2 household surveys of the U.S. adult population. The 1991 to 1992 National Longitudinal Alcohol Epidemiologic Survey and the 2001 to 2002 National Epidemiologic Survey on Alcohol and Related Conditions conducted face‐to‐face interviews with a multistage cluster sample of individuals 18 years of age and older in the continental United States. Treatment utilization represented both total utilization and the use of alcohol services. Data analyses were prevalence rates and multivariate logistic regressions for lifetime utilization with drinkers and individuals with alcohol use disorders (AUDs). Results: From 1991–1992 to 2001–2002, drinking‐related emergency room and human services use increased for drinkers, while total utilization and the use of private health professional services and mutual aid decreased for individuals with AUDs. In drinkers and individuals with AUDs, blacks and Hispanics were less likely than whites to use private health professional care. Hispanics with AUDs were less likely than whites with AUDs to use alcohol or drug programs. Ethnicity interacted with alcohol severity to predict alcohol services utilization. At higher levels of alcohol severity, blacks and Hispanics were less likely than whites to ever use treatment and to use alcohol services (i.e., human services for Hispanic drinkers, mental health services for blacks with AUDs, and mutual aid for Hispanics with AUDs). Conclusions: Our findings showed increases from 1991–1992 to 2001–2002 in alcohol services utilization for drinkers, but reductions in utilization for individuals with AUDs. Blacks and Hispanics, particularly those at higher levels of alcohol severity, underutilized treatment services compared to whites. These utilization trends for blacks and Hispanics may reflect underlying disparities in healthcare access for minority groups, and language and logistical barriers to utilizing services.     

The Hispanic Paradox: Race/Ethnicity and Nativity,Immigrant Enclave Residence and Cognitive Impairment Among Older US Adults

Hispanics, and particularly foreign‐born Mexican Americans, have been shown to fare better across a range of health outcomes than might be expected given the generally higher levels of socioeconomic disadvantage in this population, a phenomena termed the “Hispanic Paradox”. Previous research on social disparities in cognitive aging, however, has been unable to address both race/ethnicity and nativity (REN) in a nationally‐representative sample of US adults leaving unanswered questions about potentially “paradoxical” advantages of Mexican ethnic‐origins and the role of nativity, socioeconomic status (SES), and enclave residence. We employ biennial assessments of cognitive functioning to study prevalent and incident cognitive impairment (CI) within the three largest US REN groups: US‐born non‐Hispanic whites (US‐NHW), US‐born non‐Hispanic blacks (US‐NHB), US‐born Mexican Americans (US‐MA), and foreign‐born Mexican Americans (FB‐MA). Data come from a nationally‐representative sample of community‐dwelling older adults in the Health and Retirement Study linked with the 2000 Census and followed over 10 years (N = 8,433). Large disadvantages in prevalent and incident CI were observed for all REN minorities respective to US‐born non‐Hispanic whites. Individual and neighborhood SES accounted substantially for these disadvantages and revealed an immigrant advantage: FB‐MA odds of prevalent CI were about half those of US‐NHW and hazards of incident CI were about half those of US‐MA. Residence in an immigrant enclave was protective of prevalent CI among FB‐MA. The findings illuminate important directions for research into the sources of cognitive risk and resilience and provide guidance about CI screening within the increasingly diverse aging US population.     

Probability and Predictors of Transition from Abuse to Dependence on Alcohol,Cannabis, and Cocaine: Results from the National Epidemiologic Survey on Alcohol and Related Conditions

Background: Little is known about the transition from substance abuse to substance dependence. Objectives: This study aims to estimate the cumulative probability of developing dependence and to identify predictors of transition to dependence among individuals with lifetime alcohol, cannabis, or cocaine abuse. Methods: Analyses were done for the subsample of individuals with lifetime alcohol abuse (n = 7802), cannabis abuse (n = 2832), or cocaine abuse (n = 815) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Estimated projections of the cumulative probability of transitioning from abuse to dependence were obtained by the standard actuarial method. Discrete-time survival analyses with time-varying covariates were implemented to identify predictors of transition to dependence. Results: Lifetime cumulative probability estimates indicated that 26.6% of individuals with alcohol abuse, 9.4% of individuals with cannabis abuse, and 15.6% of individuals with cocaine abuse transition from abuse to dependence at some point in their lives. Half of the transitions of alcohol, cannabis, and cocaine dependence occurred approximately 3.16, 1.83, and 1.42 years after abuse onset, respectively. Several sociodemographic, psychopathological, and substance use-related variables predicted transition from abuse to dependence for all of the substances assessed. Conclusion: The majority of individuals with abuse do not transition to dependence. Lifetime cumulative probability of transition from abuse to dependence was highest for alcohol, followed by cocaine and lastly cannabis. Time from onset of abuse to dependence was shorter for cocaine, followed by cannabis and alcohol. Although some predictors of transition were common across substances, other predictors were specific for certain substances.     

Prospective Follow‐Up of Empirically Derived Alcohol Dependence Subtypes in Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC): Recovery Status,Alcohol Use Disorders and Diagnostic Criteria,Alcohol Consumption Behavior,Health Status,and Treatment Seeking

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.     

Rates and correlates of relapse among individuals in remission from DSM-IV alcohol dependence: a 3-year follow-up

Background: There is little information on the stability of abstinent and nonabstinent remission from alcohol dependence in the general U.S. population. The aim of this study was to examine longitudinal changes in recovery status among individuals in remission from DSM‐IV alcohol dependence, including rates and correlates of relapse, over a 3‐year period. Methods: This analysis is based on data from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative sample of U.S. adults aged 18 years and older originally interviewed in 2001 to 2002 and reinterviewed in 2004 to 2005. The Wave 1 NESARC identified 2,109 individuals who met the DSM‐IV criteria for full remission from alcohol dependence. Of these, 1,772 were reinterviewed at Wave 2, comprising the analytic sample for this study. Recovery status at Wave 2 was examined as a function of type of remission at Wave 1, with a focus on rates of relapse, alternately defined as recurrence of any alcohol use disorder (AUD) symptoms and recurrence of DSM‐IV alcohol dependence. Logistic regression models were used to estimate the odds of relapse among asymptomatic risk drinkers and low‐risk drinkers relative to abstainers, adjusted for a wide range of potential confounders. Results: By Wave 2, 51.0% of the Wave 1 asymptomatic risk drinkers had experienced the recurrence of AUD symptoms, compared with 27.2% of low‐risk drinkers and 7.3% of abstainers. Across all ages combined, the adjusted odds of recurrence of AUD symptoms relative to abstainers were 14.6 times as great for asymptomatic risk drinkers and 5.8 times as great for low‐risk drinkers. The proportions of individuals who had experienced the recurrence of dependence were 10.2, 4.0, and 2.9%, respectively, and the adjusted odds ratios relative to abstainers were 7.0 for asymptomatic risk drinkers and 3.0 for low‐risk drinkers. Age significantly modified the association between type of remission and relapse. Differences by type of remission were not significant for younger alcoholics, who had the highest rates of relapse. Conclusions: Abstinence represents the most stable form of remission for most recovering alcoholics. Study findings highlight the need for better approaches to maintaining recovery among young adults in remission from alcohol dependence, who are at particularly high risk of relapse.     

Lifetime drinking history in patients with alcoholic liver disease and patients with alcohol use disorder without liver disease

Objective: To determine the differences in lifetime alcohol intake (LAI) and drinking patterns between patients with alcoholic liver disease (ALD) and alcohol use disorder (AUD) without notable liver injury and between males and females with ALD.

Methods: Alcohol drinking patterns were assessed using the Lifetime Drinking History (LDH) a validated questionnaire, during an outpatient visit. Patients with AUD, currently in addiction treatment, were matched for gender and age (±5 years) with the ALD group.

Results: A total of 39 patients with ALD (26 males and 13 females; median age 58) and equal number of AUD patients were included (median age 56 years). The onset age for alcohol drinking and duration of alcohol consumption was similar in ALD and AUD. The number of drinking days was higher in women with ALD than in women with AUD: 4075 [(3224–6504) versus 2092 (1296–3661), p?=?.0253]. The LAI and drinks per drinking day (DDD) were not significantly different between patients with ALD and AUD. Females with ALD had lower LAI than males with ALD: 32,934 (3224–6504) versus 50,923 (30,360–82,195), p?=?.0385, fewer DDD (p?=?.0112), and lower proportion of binge drinking as compared to males with ALD (p?=?.0274).

Conclusions: The total LAI was similar in patients with ALD and AUD. The number of drinking days over the lifetime was associated with the development of ALD in females. Females with ALD had significantly lower alcohol consumption than men with ALD despite similar duration in years of alcohol intake which supports the concept of female propensity of ALD.     

Differences between treatment-seeking and non-treatment-seeking participants in medication studies for alcoholism: do they matter?

Background: Medication development for alcoholism typically includes experimental pharmacology studies with non-treatment-seeking individuals with alcohol use disorder (AUD) paving the way for randomized controlled trials in treatment-seekers with AUD. Objectives: The goal of this study is to provide a direct comparison between AUD treatment-seeking research participants and non-treatment-seeking participants on demographic and clinical variables and to test whether variables that differentiate the two groups are associated with clinical outcomes. Method: Non-treatment-seeking AUD participants (n = 213; 76.3% male) who completed behavioral pharmacology studies were compared to treatment-seekers who completed the COMBINE Study (n = 1383; 69.1% male) on demographic and clinical variables. Analyses examined whether the variables that differentiated the two groups predicted treatment outcomes in the COMBINE Study. Results: Analyses revealed that treatment-seeking participants were older, had more years of education, higher Alcohol Dependence Scale scores, higher Drinker Inventory of Consequences scores, higher Obsessive Compulsive Drinking Scale scores, a greater number of DSM-IV symptoms of AUD, longer duration of AUD, and consumed more standard drinks and more drinks per drinking day (i.e., in the past 30 days) compared to non-treatment-seeking participants. Nearly all characteristics that differed between the groups predicted at least one of the primary clinical outcomes of the COMBINE Study. Conclusions: This study highlights a host of clinical and demographic factors that differ between non-treatment-seeking and treatment-seeking research participants and the clinical significance of these variables. Differences between samples should be considered and addressed in order to promote greater consilience across stages of medication development.     

Alcohol expectancies and drinking in different age groups

Aims Because expectancies about the effects of alcohol change as drinking experience is accumulated, it is likely that the relationship of expectancy to drinking will differ with age. In this study, we examine the prediction of drinking behavior from positive and negative outcome expectancy at different ages. Design Data were collected as part of the National Alcohol Survey, using a multi‐stage area probability sample of the household population of the 48 contiguous United States. Participants US residents aged 12 and older (n = 2875). Measurements Survey questions included drinking habits (frequency, quantity, frequency of drunkenness, maximum quantity) and beliefs about the effects of alcohol (alcohol expectancies). Findings Structural equation models tested the relationship of positive and negative expectancy to drinking behavior in six age groups. Outcome expectancy accounted for a larger portion of the variance in drinking among younger respondents than among older respondents. However, suppression effects were common. When suppression effects were considered, positive expectancy predicted drinking better than negative expectancy only among respondents under 35, while negative expectancy was a better predictor of drinking status in most respondents over 35 years. Among drinkers, positive expectancy predominated over negative expectancy when suppression effects were considered. Conclusions These results suggest that negative expectancy predicts abstention, while positive expectancy predicts level of drinking among drinkers. In expectancy research, differences between drinkers and abstainers, age of participants and the presence of suppression effects should be taken into account.     

Age differences in diagnostic criteria of DSM-IV alcohol dependence among adults with similar drinking behaviour

Aims To test age differences in the prevalence of DSM‐IV alcohol dependence (AD) diagnostic criteria in the adult general population while controlling for drinking behaviour. Design and setting Cross‐sectional data from the 2006 German Epidemiological Survey of Substance Abuse (ESA) were used, applying a two‐stage probability sampling design. The survey used self‐administered questionnaires and telephone interviews (mixed‐mode design; 45% response rate). Participants The analytical sample consisted of n = 6984 individuals aged 18–64 years reporting alcohol consumption within the previous year. Measurements Age effects on individual AD criteria were estimated using logistic regression models, adjusting for eight mutually exclusive drinking groups (defined in terms of average daily alcohol intake and episodic heavy drinking) and socio‐economic variables. Findings When controlling for drinking behaviour, 18–24‐year‐olds were more likely to meet the criteria ‘tolerance’, ‘larger/longer’ and ‘time spent’ relative to older age groups. In contrast, the likelihood of experiencing ‘withdrawal’ symptoms increased with age. There was no significant age effect on the diagnosis of AD. Conclusions Age differences in the prevalence of specific alcohol dependence diagnostic criteria such as ‘tolerance’, ‘drinking larger amount or for longer than intended’ and ‘time spent recovering’ cannot be fully explained by differences in drinking behaviour.     

DSM-IV to DSM-5: the impact of proposed revisions on diagnosis of alcohol use disorders

Aims To determine the prevalence of past 12‐month DSM‐5 alcohol use disorders (AUDs), to quantify and characterize individuals who remain stably unaffected or affected and those who ‘switch’ diagnostically between DSM‐IV and DSM‐5 classifications. Design Data from the nationally representative wave 2 of the National Epidemiological Survey of Alcohol and Related Conditions (NESARC) collected in 2004–05. Setting General population survey. Participants All surveyed participants (n = 34 653, aged 21 years and older) and 29 993 individuals reporting life‐time alcohol use across both waves of NESARC. Measurements DSM‐IV and DSM‐5 criteria were coded using proposed guidelines. Findings The prevalence of DSM‐5 AUDs was 10.8% with the corresponding prevalence of DSM‐IV abuse/dependence being 9.7%, implying a modest 11.3% increase. Those who switched diagnostically from affected to unaffected (19.6% of DSM‐IV affected) were most likely to have endorsed hazardous use, due particularly to drinking and driving, while those who transitioned from unaffected to affected (3.3% of DSM‐IV unaffected) were primarily DSM‐IV diagnostic orphans reporting larger/longer and quit/cut‐back. Dropping the legal criterion did not affect the prevalence significantly, while the addition of craving also had a relatively modest impact on prevalence. Conclusion The proposed DSM‐5 revisions eliminate successfully individuals diagnosed previously with DSM‐IV alcohol abuse due primarily to hazardous use alone and incorporate diagnostic orphans into the diagnostic realm. Definitions of craving and importantly, hazardous use require considerable attention as it is likely that they will contribute to variations in reports of increased prevalence of alcohol use disorders between DSM‐IV to DSM‐5.     

The Alcohol Dependence Syndrome, 30 years later: a commentary. the 2006 H. David Archibald lecture

AIMS: Major classification systems for alcohol use disorders (DSM-IV and ICD-10) contain elements of the 1976 Edwards and Gross formulation of the Alcohol Dependence Syndrome (ADS). However, issues remain about the criteria that identify Alcohol Dependence (AD) as distinct from Alcohol Abuse (AA) in DSM-IV and Harmful Use in ICD-10. These issues, in part, have their roots in changing historical perceptions of alcohol use and its problems. We discuss current diagnostic criteria for AA and AD, collectively called Alcohol Use Disorders (AUDs), in the context of their historical evolution; research progress in understanding alcohol problems, including alcohol dependence; new findings on the severity of AUDs as classified by DSM-IV; and the role of alcohol consumption patterns in future classifications of AUDs. METHODS: This paper is based largely on the 2006 H. David Archibald Lecture. Parts of the original lecture have been modified to reflect more recent findings from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) of the US National Institute on Alcohol Abuse and Alcoholism (NIAAA). RESULTS: The original Edwards and Gross ADS construct is supported by advances in biological and behavioral science over the past 30 years. New findings indicate that DSM-IV AA and AD are not diagnostically distinct entities, but represent a continuum of severity of AUDs. The ADS criteria may best represent one quantifiable dimension of alcohol use problems and this scale can be related to that of the frequency of harmful patterns of drinking. CONCLUSION: The Edwards and Gross ADS criteria can be used as the basis for beginning the development of scalable multi-dimensional criteria for diagnosing AUDs in new initiatives to revise DSM-IV and ICD-10.     

Social networks and alcohol use disorders: findings from a nationally representative sample

Background: While some argue that social network ties of individuals with alcohol use disorders (AUD) are robust, there is evidence to suggest that individuals with AUDs have few social network ties, which are a known risk factor for health and wellness. Objectives: Social network ties to friends, family, co-workers and communities of individuals are compared among individuals with a past-year diagnosis of alcohol dependence or alcohol abuse to individuals with no lifetime diagnosis of AUD. Method: Respondents from Wave 2 of the National Epidemiologic Survey on Alcohol Related Conditions (NESARC) were assessed for the presence of past-year alcohol dependence or past-year alcohol abuse, social network ties, sociodemographics and clinical characteristics. Results: Bivariate analyses showed that both social network size and social network diversity was significantly smaller among individuals with alcohol dependence, compared to individuals with alcohol abuse or no AUD. When social and clinical factors related to AUD status were controlled, multinomial logistic models showed that social network diversity remained a significant predictor of AUD status, while social network size did not differ among AUD groups. Conclusion: Social networks of individuals with AUD may be different than individuals with no AUD, but this claim is dependent on specific AUD diagnosis and how social networks are measured.     

Disparities in Influenza Vaccine Coverage in the United States, 2008

OBJECTIVES: To determine the distribution of influenza vaccine coverage in the United States in 2008. DESIGN: Cross‐sectional analysis. SETTING: The 2008 Behavioral Risk Factor Surveillance Survey, which employs random‐digit dialing to interview noninstitutionalized adults in the United States and territories. PARTICIPANTS: Two hundred forty‐nine thousand seven hundred twenty‐three persons aged 50 and older. MEASUREMENTS: Participants were asked whether they had had an influenza vaccination during the previous 12 months. RESULTS: In 2008, 42.0% of adults aged 50 to 64 and 69.5% of adults aged 65 and older reported receiving an influenza vaccination in the past 12 months. Vaccine coverage generally increased with advancing age (P<.001), higher levels of education (P<.001) and total household income (P<.001), and greater morbidity (P<.001). In participants aged 50 to 64, vaccine prevalence was lower in men (39.9%) than in women (44.1%; P<.001), although no significant differences were observed in older adults. Within each 5‐year interval of age, non‐Hispanic blacks and Hispanics had significantly lower vaccine prevalence than non‐Hispanic whites (P<.001 for all comparisons). For participants aged 65 and older, non‐Hispanic blacks and Hispanics were 56% (adjusted prevalence ratio (PR)=1.56, 95% confidence interval (CI)=1.48, 1.64) and 44% (adjusted PR=1.44, 95% CI=1.35, 1.54) more likely, respectively, to be unvaccinated than non‐Hispanic whites, adjusting for age and sex. Racial and ethnic disparities in vaccine coverage narrowed with increasing number of diseases, although these disparities remained significant in older adults with two or more diseases (P<.05). CONCLUSION: There were large disparities in influenza vaccine coverage in 2008, particularly across race and ethnicity and socioeconomic position. Accordingly, more targeted interventions are needed to improve vaccine delivery to disadvantaged segments of the U.S. population.     

Improvement in quality of life among women and men aged 60 years and older following treatment for alcohol use disorder

Background

Previous studies have yielded mixed results on the association between gender and alcohol use disorder (AUD) treatment outcomes. Thus, additional research is needed to determine the effect of gender on AUD treatment outcomes, including quality of life (QoL), particularly among older adults.

Aims

In a clinical sample of older adults with DSM-5 AUD, we examined changes in QoL from the beginning of AUD treatment through 1 year of follow-ups. We also examined the effect of gender and explored interaction effects with gender on QoL.

Methods

We utilized data from the “Elderly Study,” a multi-national, single-blind, randomized, controlled trial of 693 adults aged 60+ with DSM-5 AUD. Alcohol use was assessed with the Form-90, and QoL with the brief version of the World Health Organization QoL measure. Information was collected at treatment initiation and at 4-, 12-, 26-, and 52-week follow-ups. Multilevel mixed-effects logistic and linear regression models were used to examine QoL changes and the effect of gender on changes in QoL.

Results

Following treatment, small, but significant improvements were seen over time in overall perceived health (p < 0.05). Improvements that persisted over the 1-year follow-up period were seen in the QoL domains of physical health (β: 2.6, 95% CI: 1.4–3.9), psychological health (β: 3.5, 95% CI: 3.3–3.8), social relationships (β: 4.0, 95% CI: 2.5–5.6), and environmental health (β: 1.4, 95% CI: 0.4–2.4). No significant changes were seen over time in overall perceived QoL (p = 0.58). Gender was not associated with changes in any of the QoL outcome measures (all p ≥ 0.05).

Conclusions

Among 60+ year-old adults receiving treatment for DSM-5 AUD, improvements in QoL were achievable and maintained over time, but were not associated with gender.     

Commentary on Boyd et al. (2012): Debunking myths about methadone and crime

Aims To identify independent risk factors of the recurrence of alcohol dependence (AD) in people with a remitted disorder at baseline and persistence of AD in people with a current disorder at baseline. Design Prospective cohort study with assessments at baseline and 2‐year follow‐up. Setting Recruitment from the general population, primary care and out‐patient mental health‐care services. Participants People with remitted AD (n = 253) and current AD (n = 135). Measurements Recurrence and persistence of AD during 2‐year follow‐up were established using the Composite International Diagnostic Interview (CIDI) interview based on DSM‐IV. Logistic regression analyses were performed to explore the role of potential risk factors (i.e. baseline severity of alcohol problems, measures for depression and anxiety, socio‐demographics, vulnerability factors and addiction‐related factors) as independent predictors of a negative course. Findings Overall recurrence and persistence rates of AD were 14.6 and 40.7%, respectively, and were highly conditional on the severity of alcohol problems [adjusted odds ratio (OR) per standard deviation (SD) increase: OR = 3.64, 95% confidence interval (CI): 2.21–6.01 and OR = 2.12, 95% CI: 1.32–3.40, respectively). Severity of depressive/anxiety symptoms was an additional independent predictor of the recurrence of AD, whereas male gender and high education were significant independent risk factors of the persistence of AD. Conclusions Alcohol dependence has a dynamic course, with only moderate levels of diagnostic stability. Both recurrence and persistence of alcohol dependence are highly dependent on severity of baseline alcohol problems, whereas severity of depressive/anxiety symptoms predicts only the recurrence of alcohol dependence. Both measures may be useful in identifying people at an increased risk of a negative course and who could be targeted by prevention strategies.     

Discrepancies in estimates of prevalence and correlates of substance use and disorders between two national surveys

AIM: To assess the degree to which methodological differences might influence estimates of prevalence and correlates of substance use and disorders by comparing results from two recent surveys administered to nationally representative US samples. METHODS: Post-hoc comparison of data from the 2002 National Survey on Drug Use and Health (NSDUH) with data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) administered in 2001-02. RESULTS: Prevalence estimates for all substance use outcomes were higher in the NSDUH than in the NESARC; ratios of NSDUH to NESARC prevalences ranged from 2.1 to 5.7 for illegal drug use outcomes. In the NSDUH, past-year substance use disorder (SUD) prevalence estimates were higher for cocaine and heroin, but were similar to NESARC estimates for alcohol, marijuana and hallucinogens. However, prevalence estimates for past-year SUD conditional on past-year use were substantially lower in the NSDUH for marijuana, hallucinogens and cocaine. Associations among drug and SUD outcomes were substantially higher in the NESARC. Total SUD prevalence did not differ between surveys, but estimates for blacks and Hispanics were higher in the NSDUH. CONCLUSION: A number of methodological variables might have contributed to such discrepancies; among plausible candidates are factors related to privacy and anonymity, which may have resulted in higher use estimates in the NSDUH, and differences in SUD diagnostic instrumentation, which may have resulted in higher SUD prevalence among past-year substance users in the NESARC.     

Alcohol screening in young persons attending a sexually transmitted disease clinic

OBJECTIVE: To compare the ability of 3 brief alcohol screens (Alcohol Use Disorders Identification Test [AUDIT], CRAFFT, and CAGE) to identify adolescents and young adults with a current alcohol use disorder (AUD) and to determine whether there are gender-based or race-based differences in screening performance. DESIGN, PARTICIPANTS, AND SETTING: Cross-sectional study of 358 young persons (55% males; 49% blacks; age range, 15-24 years; mean age, 20.6 years) who were attending an urban clinic for sexually transmitted diseases and reported alcohol use during the past year. MEASUREMENTS: Receiver operating characteristic (ROC) curve analysis was used to determine the ability of the 3 screens to discriminate between participants with and without AUDs detected in the Structured Clinical Interview for DSM-IV (SCID). RESULTS: One third (33%) of participants met Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria for a current AUD (24% with alcohol abuse and 9% with alcohol dependence). The AUDIT performed best at a cut score of 9 (sensitivity, 0.76; specificity, 0.79), CRAFFT at a cut score of 2 (sensitivity, 0.94; specificity, 0.33), and CAGE at a cut score of 1 (sensitivity, 0.69; specificity, 0.63). The AUDIT had the best overall performance (area under the curve [AUC], 0.84), followed closely by CRAFFT (AUC, 0.79) and then CAGE (AUC, 0.70). Performance of screens did not differ by gender. The AUDIT performed slightly better in whites than blacks, but no race-based differences were observed for the CAGE or CRAFFT. CONCLUSIONS: Clinicians should use the AUDIT or CRAFFT, rather than the CAGE, to screen young persons for AUDs. The AUDIT performs best, but its length may limit its utility in this setting. The CRAFFT is a suitable alternative, with excellent sensitivity and no gender-based or race-based differences.
