Abstract
Compiling evidence supports that selenium plays a vital role in glucose metabolism. Triglyceride-glucose index (TyG) and triglyceride-glucose-body mass index (TyG-BMI) are commonly used in epidemiologic studies to evaluate insulin resistance and cardiovascular disease (CVD) risks. This study is aimed to investigate the association between whole blood selenium concentration and TyG and TyG-BMI. A total of 6290 participants (age ≥ 20 years) from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 were included. Multiple linear regression models were used to examine the association between blood selenium quartiles and TyG and TyG-BMI. Subgroup analysis stratified by diabetes status was also performed. The adjusted model showed a positive association between TyG and blood selenium concentration (β [95%CI] = 0.099 [0.063, 0.134], p < 0.001) and TyG-BMI (β [95%CI] = 3.185 [2.102, 4.268], p < 0.001). The association persisted after stratification by diabetes status (p < 0.001). Participants were stratified into four quartiles based on selenium concentration (Q1: 1.08-2.24 μmol/L, Q2: 2.25-2.42 μmol/L, Q3: 2.43-2.62 µmol/L, Q4: 2.63-8.08). Compared with the Q1 group, TyG in the Q3 and Q4 groups was significantly higher (β = 0.075 [95%CI 0.039 to 0.112] and β = 0.140 [95%CI 0.103 to 0.176], respectively). Additionally, TyG-BMI in the Q2, Q3, and Q4 groups was higher than that in the Q1 group (β = 1.189 [95%CI 0.065 to 2.314], β = 2.325 [95%CI 1.204 to 3.446], and β = 4.322 [95%CI 3.210 to 5.435], respectively). Blood level of selenium was positively associated with TyG and TyG-BMI, indicating that excessive blood selenium may be associated with impaired insulin sensitivity and increased risk of cardiovascular disease.

Abstract
AIMS To estimate change in young people's alcohol consumption during COVID-19 restrictions in Australia in early-mid 2020, and test whether those changes were consistent by gender and level of consumption prior to the pandemic. DESIGN Prospective longitudinal cohort. SETTING Secondary schools in New South Wales, Tasmania and Western Australia. PARTICIPANTS Subsample of a cohort (n = 443) recruited in the first year of secondary school in 2010-11. Analysis data included three waves collected in September 2017-July 2018, September 2018-May 2019 and August 2019-January 2020), and in May-June 2020. MEASUREMENTS The primary predictors were time, gender and level of consumption prior to the pandemic. Outcome variables, analysed by mixed-effects models, included frequency and typical quantity of alcohol consumption, binge drinking, peak consumption, alcohol-related harm and drinking contexts. FINDINGS Overall consumption (frequency × quantity) during the restrictions declined by 17% [incidence rate ratio (IRR) = 0.83; 95% confidence interval (CI) = 0.73, 0.95] compared to February 2020, and there was a 35% decline in the rate of alcohol-related harms in the same period (IRR = 0.66; 95% CI = 0.54, 0.79). Changes in alcohol consumption were largely consistent by gender. CONCLUSIONS From a survey of secondary school students in Australia, there is evidence for a reduction in overall consumption and related harms during the COVID-19 restrictions.

Abstract
Alcohol consumption is an important predictor of a variety of negative outcomes. There is an extensive literature that examines the differences in the estimated level of alcohol consumption between types of assessments (e.g., quantity-frequency [QF] questionnaires, daily diaries). However, it is typically assumed that all QF-based measures are nearly identical in their assessment of the volume of alcohol consumption in a population. Using timeline follow-back data and constructing common QF consumption measures, we examined differences among survey instruments to assess alcohol consumption and heavy drinking. Using three data sets, including clinical to community samples, we demonstrate how scale-specific item characteristics (i.e., number of response options and ranges of consumption assessed by each option) can substantially affect the estimated mean level of consumption and estimated prevalence of binge drinking. Our analyses suggest that problems can be mitigated by employing more resolved measures of quantity and frequency in consumption questionnaires.

Abstract
Elevated alcohol reward value (RV) has been linked to higher levels of drinking and alcohol-related consequences, and there is evidence that specific drinking motives may mediate the relationship between demand and problematic alcohol use in college students, making these variables potentially important indicators of risk for high RV and alcohol problems. The present study evaluated these relationships in a high-risk sample of military veterans. Heavy-drinking (N = 68) veterans of Operations Enduring Freedom or Iraqi Freedom (OEF/OIF) completed the alcohol purchase task (APT) measure of alcohol demand (RV), and standard assessments of alcohol consumption, alcohol-related problems, and drinking motives. RV was associated with overall alcohol consequences, interpersonal alcohol consequences, social responsibility consequences and impulse control consequences. Mediation analyses indicated significant mediation of the relationships between RV and a number of problem subscales by social motives, coping-anxiety motives, coping-depression motives and enhancement motives. This suggests that individuals who have a high valuation of alcohol may have increased motivation to drink in social, mood-enhancement, and coping situations, resulting in increased alcohol-related consequences. Demand and drinking motives should be examined as potential indicators of need for intervention services and as treatment targets in veterans. (PsycINFO Database Record

Abstract
A randomized clinical trial of culturally adapted and unadapted motivational interviewing to reduce drinking and related problems among heavy drinking Latinos assessed 57 participants at baseline and at 2 (86% retention) and 6 months (84% retention) after treatment. Significant decreases across both treatments were found in heavy drinking days per month and drinking consequences (p < .001), with greater reductions for drinking consequences for culturally adapted motivational interviewing at 2 months (p = .009) and continuing reductions in culturally adapted motivational interviewing at 6 months. Findings provide preliminary support for the value of cultural adaptation to enhance the efficacy of motivational interviewing with Latino heavy drinkers.

Abstract
AIMS This study compares current 12-month drinkers who do not report drinking in the last 30 days with current drinkers who drank in the last 30 days and assesses possible misclassification errors from use of a 30-day consumption measure. DESIGN Data are from the 2005 US National Alcohol Survey (n = 6919), a national household probability survey. SETTING Telephone interviews were used to measure alcohol use and alcohol-related problems. PARTICIPANTS This study compared 1300 current drinkers who did not drink in the last 30 days with 2956 current drinkers who drank in the last 30 days. MEASUREMENTS Volume was measured by quantity/frequency scales (12-month and 30-day) and a graduated frequency scale (12-month). Both groups were compared by demographic, alcohol volume, days of five or more drinks, social consequences and dependence measures. FINDINGS Results indicate a significantly lower prevalence rate of current drinking for 30-day measures-47.3% (45.8%, 48.8%) versus 67.3% (66.0%, 68.7%) with 12-month measures. Further, 385 non-30-day drinkers reported 12-month drinking frequencies of once a month or more often, suggesting possible inconsistent reporting of their alcohol use. When this group of 'inconsistent' respondents is compared with the 915 non-30-day current drinkers who reported less than monthly drinking, they reported significantly higher yearly volume, days of five or more drinks, mean social consequences and proportion reporting alcohol dependence. CONCLUSIONS In population surveys assessing alcohol use, asking about the previous 12 months rather than the past 30 days provides higher estimates of current use, including more days of heavy episodic use.

Abstract
Background Numerous studies have documented a profound reduction in alcohol use among pregnant women, whereas research on expectant fathers has been scarce. The aim of this study was to measure changes in alcohol consumption from before pregnancy to 17 weeks in gestation for mothers and fathers, differentiating between parents with and without any previous children, and to measure how level and change in alcohol consumption into early pregnancy was associated with relationship satisfaction. Methods The data collection was conducted as part of the Norwegian Mother and Child Cohort Study (MoBa) at the Norwegian Institute of Public Health. This cohort now includes 108 000 children, 90 700 mothers and 71 500 fathers recruited from 1999 to 2008. The present study comprises 82 362 couples. Alcohol consumption was assessed using a questionnaire including items about usual drinking frequency, quantities, and number of occasions with heavy episodic drinking (HED). Relationship satisfaction was measured by five items scored on a Likert agreement scale. Results The findings indicate that both mothers and fathers reduce their drinking significantly during pregnancy. Reduction was apparent for all three measures of alcohol consumption. First-time fathers reduced their alcohol consumption more than experienced fathers, from initially higher levels. The gap between the fathers and their pregnant partner was greater for first-time parents compared to parents with previous children. Drinking pre-pregnancy and relationship satisfaction during pregnancy were weakly related within each partner, whereas no association across partners was observed. Conclusions Both expectant mothers and fathers changed their alcohol consumption patterns when expecting a child. Almost all mothers stopped drinking, whereas fathers reduced their drinking to a considerable degree. Relationship satisfaction was only slightly related to their drinking patterns. The findings may have important policy implications, mainly with regard to developing alcohol preventive strategies.

Abstract
BACKGROUND This paper examines the prevalence, the symptom profile, and the drinking and sociodemographic predictors of current (past 12 months) DSM-IV alcohol abuse and dependence among Mexican Americans living along the U.S.-Mexico border and those living in metropolitan areas away from the border. METHODS Respondents in the non-border areas (primarily Houston and Los Angeles) constitute a multistage probability sample (N = 1,288) of these areas, interviewed as part of the 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS). Respondents in the border area (N = 1,307) constitute a household probability sample of Mexican Americans living on the border. In both surveys, data were collected during computer-assisted interviews conducted in respondents' homes. The HABLAS and the border sample response rates were 76 and 67%, respectively. RESULTS Although bivariate analyses revealed no overall differences between border and non-border locations, (negative) age trends were more pronounced on the border for male abuse and for dependence among both genders. Among females aged 18 to 29, border residence was linked to significantly higher rates of dependence. In multivariable analyses, the prevalence of male abuse declined more rapidly with age on the border than off the border. Other unique predictors of male abuse were Jewish/other religion and weekly volume of alcohol consumption. Being married or out of the workforce, attaining a higher education, having no religious preference, and weekly volume uniquely predicted female dependence. Age and weekly volume uniquely predicted male dependence. CONCLUSIONS The prevalence of alcohol use disorders among Mexican Americans on and off the U.S.-Mexico border largely mirrors previously documented patterns of alcohol consumption in these areas. For young Mexican American women in particular, border residence is linked to heightened vulnerability to alcohol dependence.

Abstract
Alcohol is the 5th leading risk factor to the global disease burden and disability and about half of the global alcohol burden was attributable to injuries. Despite a large body of evidence documenting the associations between alcohol and injuries, data from Asian countries including South Korea are sparse. The aim of this study was to investigate the associations between episodic heavy past-year drinking, problem drinking symptomatic of alcohol dependence and alcohol-related and intentional injuries. Data from 1989 injured patients recruited for the WHO/NIAAA Collaborative Study on Alcohol and Injury in South Korea were analyzed with respect to the prevalence rates and associations between injuries and frequency of past-year episodic heavy drinking and problem drinking. In estimating the odds ratios (ORs) and the associated 95% confidence intervals between alcohol intake and injuries multivariable logistic models were employed to adjust for sociodemographic characteristics and selected drinking variables. All analyses were conducted using the SAS 9.2 software. Findings of this study were consistent with prior studies that the risk of alcohol-related or intentional injury was positively associated with the frequency of episodic heavy drinking. The magnitudes of the associations were larger with frequent consumption of 5+ drinks (OR=4.0 approximately) than with frequent consumption of 12+ drinks (OR=3.1). Strong associations were also noted between RAPS4-assessed alcohol dependence and alcohol-related and intentional injuries. Further, the prevalence of intentional injury and its association with alcohol increased sharply once the acute alcohol intake exceeded 90 ml. Our results were consistent with prior studies that episodic heavy consumption, acute intoxication and problem drinking are pervasive among emergency room patients. Results of our study also lent support for administering a single-item screener querying consumption of 5+ drinks at a sitting in the past 12 months as a triage tool in Korea.

Abstract
OBJECTIVE: To examine the association between acculturation, birthplace, and alcohol-related social problems across Hispanic national groups. METHOD: 5,224 Hispanic adults (18+ years) were interviewed using a multistage cluster sample design in Miami, New York, Philadelphia, Houston, and Los Angeles. RESULTS: Multivariate analysis shows no association between acculturation and problems among men or women. Birthplace is a risk factor for social problems among both genders. Among men, Mexican Americans, Puerto Ricans, and South/Central Americans are more likely to report social problems than Cuban Americans. Other risk factors for men are unemployment, a higher volume of drinking, and a higher frequency of binge drinking. Among women, Mexican American origin and binge drinking are also risk factors for reporting problems. CONCLUSIONS: U.S.-born Hispanics may experience stress and other detrimental effects to health because of their minority status, which may increase the likelihood of more drinking and the development of alcohol-related problems.

Abstract
Heavy episodic or "binge" drinking is commonly defined as drinking 4-5 drinks per occasion (5/4 definition) or drinking that results in a blood alcohol concentration (BAC) of .08%. The present study compared the validity of each binge definition as an indicator of at-risk, problem drinking. Two hundred and fifty-one college students were classified as nonbinge drinkers or as binge drinkers based on the 5/4 definition or the .08% BAC definition. The two definitions of binge drinking were examined in terms of their sensitivity and specificity as indicators of alcohol-related problems as determined by scores on the Alcohol Use Disorders Identification Test (AUDIT). Over half the sample (56%) were at-risk drinkers according to the AUDIT. The .08% definition detected only one-half of these individuals. Gender differences were also evident. Female binge drinkers actually achieved significantly higher estimated BACs per episode than their male binge drinking counterparts. The findings suggest that drinking to a subthreshold BAC (ie, <.08%) is not sufficient to avoid alcohol-related problems, and that total quantity (ie, total standard drinks) per occasion might contribute to risk independent of the BAC achieved during drinking episodes. The findings also highlight the importance of considering frequency of consumption in determining risky drinking versus relying solely on quantity measures.

Abstract
BACKGROUND Item response theory (IRT) has been used to examine alcohol use disorder (AUD) symptoms and their psychometric properties but has not been previously applied to AUD symptoms from an American Indian sample. METHODS Lifetime DSM-IV AUD symptoms and binge drinking (5+ drinks men/4+ drinks women) at ≥1, ≥4, ≥8, and ≥15 days per month during the period of heaviest lifetime drinking criteria were assessed in 530 American Indian participants. Exploratory factor analysis was used to examine the factor structure of the 10 AUD symptoms and each alcohol consumption criterion. Two-parameter IRT models generated marginal maximum likelihood estimates for discrimination (a) and threshold (b) parameters for 10 DSM-IV AUD symptoms and each consumption criterion. Differential item functioning (DIF) analysis was used to assess AUD symptom severity in groups defined by gender and age at interview. RESULTS The AUD symptoms of "Withdrawal" and "Activities Given Up" were the most severe symptoms. "Tolerance" and "Social/Interpersonal Problems" were the least severe. All AUD symptoms fell on the moderate portion of the severity continuum, except "Withdrawal," which fell at the lower end of the severe portion. The consumption criterion of 5+/4+ (male/female) at ≥8 times per month demarcated the portion of the severity continuum where AUD symptoms began to occur at a probability of 50%. DIF analysis showed significant gender and age at interview differences for "Hazardous Use,""Tolerance," and "Activities Given Up," but not for the other AUD symptoms. CONCLUSIONS In this American Indian community sample, alcohol abuse and dependence did not represent distinct disorders. Only one AUD symptom was found outside the moderate portion of the underlying AUD severity continuum. Drinking 5+/4+ (male/female) drinks at a frequency of ≥8 times per month during the period of heaviest lifetime drinking was found to function well as both a risk and a diagnostic criterion for lifetime DSM-IV AUD. DSM-IV AUD symptom criteria, as currently assessed, may be limited in their ability to capture the full range of symptom severity of AUDs, at least in this high-risk population.

Abstract
BACKGROUND The degree to which distinct behavioral components of impulsivity predict alcohol consumption is as yet not well-understood. Further, the possibility that this relation might be more pronounced in groups characterized by heightened impulsivity (i.e., individuals with ADHD) has not been tested. METHODS The current study examined the degree to which three specific behavioral components of impulsivity (i.e., poor response inhibition, poor attentional inhibition, and increased risk-taking) were associated with quantity and frequency of alcohol consumption in a group of young adult social drinkers with ADHD (n = 33) and in a comparison control group (n = 21). Participants performed the delayed ocular return task (attentional inhibition), the cued go/no-go task (behavioral inhibition), and the balloon analogue risk task (risk-taking). RESULTS Both poor behavioral inhibition and greater risk-taking were related to greater quantity of consumption in the entire sample, whereas poor attentional inhibition was related to greater quantity specifically among those with ADHD. By contrast, only risk-taking was associated with frequency of consumption, and this was found specifically in the control group. CONCLUSIONS These findings provide important information regarding the potential role of distinct behavioral components of impulsivity in drinking behavior, and highlight unique relevance of attentional impairments to drinking behavior in those with ADHD.

Abstract
Twenty-eight patients with diabetes who screened positive for at-risk drinking were assigned to brief alcohol intervention (BAI) (n = 14) or standard care (SC) (n = 14) treatment conditions. All participants completed a baseline interview and one-, three, and six-month follow-up interviews. Across the six-month follow-up period, there was a significantly greater reduction in quantity of alcohol consumed in the BAI group. At the six-month follow-up, the BAI group had a greater reduction in quantity of alcohol consumed, percentage of heavy drinking days, and frequency of drinking. Reductions in alcohol use were associated with improved adherence in certain components of diabetes self-care behavior. The results of this study suggest that brief alcohol interventions are efficacious in reducing alcohol use among at-risk drinkers with diabetes and that reductions in alcohol use may result in some improvements in adherence to diabetes self-care behavior.

Abstract
OBJECTIVE The purpose of this study was to examine the prevalence and correlates of alcohol-related problems across four Hispanic national groups: Mexican Americans, Puerto Ricans, Cuban Americans, and South/Central Americans. METHOD Using a multistage cluster sample design, 5,224 individuals ages 18 years and older were selected from the household population of five U.S. metropolitan areas: Miami, New York, Philadelphia, Houston, and Los Angeles. RESULTS Cuban Americans had the lowest prevalence of alcohol-related problems. Significant differences across national group for zero versus two or more problems and for one versus two or more problems existed among men. Puerto Rican women were most likely to report two or more problems. The presence of zero versus two or more problems varied significantly across groups. There was variation in problem type across national groups among both men and women. Regression analyses showed that all groups were more likely than Cuban Americans to report two or more problems (vs zero) (Puerto Ricans: odds ratio [OR] = 2.02, p < .05; Mexican Americans: OR = 2.92, p < or = .01; South/Central Americans: OR = 2.12, p < or = .01). Being U.S. born (vs foreign born) increased the likelihood of experiencing one (OR = 1.57, p < .05) and two or more problems (OR = 1.95, p < or = .01). The volume of consumption was associated with problems (one problem: OR = 1.16, p < or = .01; two or more problems: OR = 1.31, p < or = .01). Heavy episodic drinking less than once a month was associated with two or more problems (OR = 6.15, p < or = .01). Heavy episodic drinking one or more times a month was associated with one problem (OR = 1.74, p < or = .01) and two or more problems (OR = 3.18, p < or = .01). CONCLUSIONS It is important to recognize that Hispanics are not a homogenous group.

Abstract
OBJECTIVE Many surveys employed to study college drinking ask whether students have had a five-drink (for men) or four-drink (for women) episode in one sitting at least once during the previous 2 weeks to indicate risky or heavy episodic drinking. However, some researchers have questioned the predictive validity of the 5/4 measure. This study tested whether such students attained extremely high blood alcohol concentrations (BACs) during the previous 30 days. METHOD Freshmen students were recruited by presentation of short screening surveys in the classroom or outside the student stores. Students who reported a risky drinking episode were invited to enroll in the study and were given a lengthy survey battery that included a computerized 30-day Timeline Followback recall of their drinking. The amount of alcohol consumed was used along with each subject's gender and weight to calculate an estimated BAC (eBAC) for each event and the maximum eBAC taken for this report. RESULTS Fifty-five percent of the 953 students who completed the screening survey met criterion for enrollment, and 381 students entered the study. The average peak calculated eBAC was 233 mg/dl. Only 9.2% of subjects did not have an eBAC value at or above the threshold for a driving while intoxicated offense, 80 mg/dl. CONCLUSIONS Students who report one recent risky drinking episode are very likely to have had at least one heavy drinking episode that generated a BAC in excess of the threshold for driving while intoxicated. Many report extremely high consumption levels. The 5/4 screening question is highly predictive of abusive drinking and can be used to identify students at severe risk for adverse events related to the consumption of alcohol.

Abstract
AIMS The aim of this study was to identify changes in patterns of alcohol consumption over a 20-year interval among older women and men, and to examine the associations between guideline-defined excessive drinking and late-life drinking problems. DESIGN, PARTICIPANTS AND MEASURES: A community sample of 719 adults between 55 and 65 years of age who consumed alcohol at or prior to baseline participated in a survey of alcohol consumption and drinking problems and was followed 10 years and 20 years later. FINDINGS The likelihood of excessive drinking declined over the 20-year interval as adults matured into their 70s and 80s. However, at ages 75-85, 27.1% of women and 48.6% of men consumed more than two drinks per day or seven drinks per week. At comparable guideline levels of alcohol consumption, older men were more likely to have drinking problems than were older women. Consumption of more than two drinks per day or seven drinks per week was identified as a potential conservative guideline for identifying excessive drinking associated with an elevated likelihood of drinking problems. CONCLUSIONS A substantial percentage of older adults who consume alcohol engage in guideline-defined excessive drinking and incur drinking problems. The finding that older men may be more likely than older women to experience problems when they drink beyond guideline levels suggests that alcohol guidelines for men should not be set higher than those for women.

Abstract
OBJECTIVE To evaluate trends in the past 30-day prevalence of binge drinking by age, sex, and student status, among youths and young adults in the United States between 1979 and 2006, a period that encompasses the federally mandated transition to a uniform legal drinking age of 21 years, and other policy changes aimed at curbing underage drinking. METHOD Data were analyzed from 20 administrations of the National Survey on Drug Use and Health, yielding a pooled sample of more than 500,000 subjects. Trends in relative risk for four different age groups, stratified by sex, relative to the 24- to 34-year-old reference group were calculated. We also examined trends in risk for binge drinking associated with student status (among college-age students) and race/ethnicity. RESULTS Significant reductions in relative risk for binge drinking over time were observed for 12- to 20-year-old males, but no changes were observed for females in this age range, and binge drinking among minority females increased. Risk for binge drinking increased among 21- to 23-year-old women, with college women outpacing nonstudents in this age range. Trends also indicate that no reduction in binge drinking occurred for college men. CONCLUSIONS Although the overall trend is toward lower rates of binge drinking among youths, likely a result of a higher legal drinking age and other changes in alcohol policy, little improvement has occurred for college students, and increases in binge drinking among women has offset improvements among youths. Understanding these specific demographic trends will help inform prevention efforts.

Abstract
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.

Alcohol consumption and quitting smoking in the International Tobacco Control (ITC) Four Country Survey. Drug Alcohol Depend 2009; 100:214-20.

Abstract
Although greater alcohol consumption has been associated with decreased odds of quitting smoking in prospective studies, the aspects of drinking most strongly associated with quitting have not been fully explored and examination of potential confounder variables has been limited. Further studies are needed to inform efforts to enhance smoking cessation among the substantial portion of smokers who drink alcohol. The present study examines: (a) drinking frequency, average weekly quantity of alcohol consumption, and frequency of heavy drinking as prospective predictors of quit smoking behaviors, (b) difference across countries in this prediction, and (c) third variables that might account for the association between alcohol consumption and quitting smoking. Data were drawn from the International Tobacco Control Four Country Survey, a prospective cohort study of smokers in Australia, Canada, the UK, and the US. A total of 4831 participants provided alcohol data at one study wave and were re-interviewed 1 year later. Individuals who drank heavily (4+/5+ drinks for women and men, respectively) more than once a week had significantly lower rates of quitting smoking than all other participants, in part due to the fact that a significantly lower proportion of those making a quit attempt remained quit for more than 1 month at follow-up. The role of frequent heavy drinking did not differ by country or sex and was not accounted for by demographics, smoking dependence, or attitudes regarding quitting smoking. Neither drinking frequency nor weekly quantity of consumption showed robust associations with quitting behaviors. Results indicate further study of interventions to address heavy drinking among smokers is warranted.

Abstract
OBJECTIVE The purpose of this study was to develop a quantitative measure of alcohol consumption for gene-mapping studies. METHOD Using a sample of 3,787 young-adult twin women and an independent sample of 489 men and women from a college drinking study, we developed an alcohol-consumption factor score indexed by (1) maximum typical consumption (log-transformed quantity frequency [LQNTFRQ]), (2) maximum drinks in a 24-hours period (LMAXALC), (3) frequency of drinking five or more drinks per day (FIVE), and (4) frequency of drinking to intoxication (INTOX). We tested (1) for factorial and psychometric equivalence across samples and genders; (2) for construct validity and its equivalence, across samples and genders, using measures of tobacco and cannabis use and family history of alcoholism; and (3) to determine the heritability of the alcohol-consumption factor score using a genetic psychometric model. RESULTS A single-factor model fit well with factor loadings ranging from .60 to .90. With rare exception, we found support for measurement invariance across the two samples and across genders. Measures of nicotine and cannabis use as well as family history of alcoholism were associated, to a similar extent across samples and genders, with the underlying alcohol-consumption factor. Psychometric twin modeling revealed that each of the alcohol-consumption measures (h2=34%-47%) and the underlying factor score (h2=50%) were heritable, with the remainder of the variance attributable to individual-specific environmental factors. This moderately heritable alcohol-consumption factor also accounted for a majority of the genetic variance in LQNTFRQ, LMAXALC, FIVE, and INTOX. CONCLUSIONS Quantitative measures of alcohol consumption with the favorable attributes of measurement invariance, construct validity, and moderate heritability can greatly enhance future gene-mapping efforts, supplementing information afforded by conventional diagnostic measures of alcohol abuse/dependence.

Abstract
Diabetes Mellitus is a serious chronic disease, affecting an increasing number of individuals worldwide. Adherence to diabetes self-care behaviors is key to the successful management of the disease. At-risk drinking is common among diabetic patients and is associated with inferior diabetes treatment adherence and outcomes, resulting in increased mortality and morbidity. Furthermore, individuals with diabetes who engage in at-risk drinking are also in danger of incurring the negative consequences of at-risk drinking found in the general population. Research suggests that alcohol use screening and intervention do not commonly occur during the course of primary care treatment for diabetes. While methods for reducing alcohol use in this population have been largely unexplored to date, brief interventions to reduce at-risk drinking have been well-validated in other patient populations and offer the promise to reduce at-risk drinking among diabetic patients, resulting in improved diabetes treatment adherence and outcomes.

Abstract
BACKGROUND Recent investigations using item response modeling have begun to conceptualize alcohol consumption, problems, and dependence as representing points along a single continuum of alcohol involvement. Such a conceptualization may be of particular benefit to measurement of alcohol involvement in adolescents, but investigations to date have been limited to adult samples and may not generalize to adolescents due to age-related developmental differences. METHODS This study used Rasch model analyses to examine the properties of indices of alcohol consumption and problems among 6,353 adolescents, aged 12 to 18 years, in Wave 1 of the Add Health survey. A particular focus was on whether the functioning of items changed when these adolescents were re-interviewed in Wave 3 when they were 18 to 24 years of age. RESULTS Rasch model analyses supported the unidimensionality and additive properties of the items in the Wave 1 data. Comparisons of Wave 1 and Wave 3 data indicated differential item functioning in most of the items such that items related to alcohol consumption were more severe during adolescence, whereas items related to alcohol problems were more severe in young adulthood. CONCLUSIONS A valid index of alcohol involvement in adolescents can be constructed combining indices of alcohol consumption and alcohol problems. Such an index covers a range of severity and functions similarly across sex and race/ethnicity. A similar index can be constructed in young adulthood. However, the interpretation of scores must be attentive to developmental differences. In particular, for adolescents, indices of alcohol consumption are relatively closer in severity to indices of alcohol problems than they are among young adults. Thus, alcohol problems are more likely among adolescents than young adults given a similar level of drinking.

Abstract
BACKGROUND Extended-release naltrexone (XR-NTX) is a once-a-month injectable formulation for the treatment of alcohol dependence previously shown to reduce drinking and heavy drinking relative to placebo (Garbutt et al., 2005). A 24-week, randomized, double-blind, placebo-controlled study established the efficacy and safety of XR-NTX in this patient population. In this report, the effect of XR-NTX on quality of life (QOL) was examined. METHODS Alcohol-dependent patients were randomly assigned to receive XR-NTX 380 mg (N = 205), XR-NTX 190 mg (N = 210), or placebo (N = 209), combined with a standardized psychosocial intervention. QOL was assessed using the Medical Outcomes Study 36-item short-form health survey, administered at baseline and at 4-week intervals during 24 weeks of treatment. RESULTS Compared with U.S. population norms, patients showed initial impairment in the health-related QOL domains of mental health, social functioning, and problems with work or other daily activities due to emotional problems. Adherence to all 6 injections was 65% for XR-NTX 190 mg, 63% for XR-NTX 380 mg, and 64% for placebo. Generalized estimating equations analyses using an intention-to-treat sample revealed that XR-NTX 380 mg was associated with significantly greater improvements from baseline in mental health (p = 0.0496), social functioning (p = 0.010), general health (p = 0.048), and physical functioning (p = 0.028), compared with placebo. Linear regression analyses revealed that reductions from baseline in drinking (percentage of drinking days and percentage of heavy drinking days in the last 30 days) were significantly (p < 0.05) correlated with improvements in quality of life. CONCLUSION Extended-release naltrexone 380 mg in combination with psychosocial intervention was associated with improvements in QOL, specifically in the domains of mental health, social functioning, general health, and physical functioning.

Abstract
AIM To review and discuss measurement issues in survey assessment of alcohol consumption for epidemiological studies. METHODS The following areas are considered: implications of cognitive studies of question answering such as self-referenced schemata of drinking, reference period and retrospective recall, as well as the assets and liabilities of types of current (e.g. food frequency, quantity-frequency, graduated frequencies and heavy drinking indicators) and life-time drinking measures. Finally we consider units of measurement and improving measurement by detailing the ethanol content of drinks in natural settings. RESULTS AND CONCLUSIONS Cognitive studies suggest inherent limitations in the measurement enterprise, yet diary studies show promise of broadly validating methods that assess a range of drinking amounts per occasion; improvements in survey measures of drinking in the life course are indicated; attending in detail to on- and off-premise drink pour sizes and ethanol concentrations of various beverages shows promise of narrowing the coverage gap plaguing survey alcohol measurement.

Abstract
Although the heavy episodic drinking (HED) measure of 5+ drinks (sometimes 4+ for women) is used extensively, there is no empirical basis for the designation of 5 drinks as the threshold (vs. another threshold that may perform equally). The present study sought to determine the threshold for HED that maximally predicts proximal and distal adverse-drinking-related outcomes. Participants included 115 young adults (57% female; 96% Caucasian) who partook in an 8-week Internet survey that assessed daily drinking as well as next-day hangover; 10 months later, adverse outcomes (problem drinking, alcohol-related problems, maximum number of drinks, and drug use) were surveyed. Thresholds were computed, with a range from 1+ drinks to 15+ drinks, and outcomes were predicted from each threshold. Findings for hangover measures showed relatively good convergence across multiple indicators, with greatest prediction occurring at a threshold of 10+ drinks per occasion. Different thresholds were observed for long-term outcomes, with higher thresholds indicative of outcomes with greater severity. Although alternatives to HED, such as subjective effects and blood alcohol concentration, can indicate risky drinking, a threshold measure of HED may have advantages in terms of prevention and of intervention efforts.

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

Abstract
OBJECTIVES We used several different guidelines for appropriate alcohol use to identify patterns of high-risk alcohol consumption among older women and men and examined associations between these patterns and late-life alcohol use problems. METHODS A sample of 1291 older adults participated in a survey of alcohol consumption and alcohol use problems and was studied again 10 years later. RESULTS Depending on the guideline, 23% to 50% of women and 29% to 45% of men engaged in potentially unsafe alcohol use patterns. The likelihood of risky alcohol use declined over the 10 years; however, the numbers of drinks consumed per week and per day were associated with alcohol use problems at both assessment intervals. CONCLUSION Our findings imply that guidelines for alcohol consumption should be no more liberal for older men than for older women.

Abstract
OBJECTIVES Data from the 1984, 1990, and 1995 National Alcohol Surveys were used to investigate whether declines shown previously in drinking and heavy drinking across many demographic subgroups have continued. METHODS Three alcohol consumption indicators--current drinking (vs abstaining), weekly drinking, and weekly heavy drinking (5 or more drinks in a day)--were assessed for the total US population and for demographic subgroups. RESULTS Rates of current drinking, weekly drinking, and frequent heavy drinking, previously reported to have decreased between the 1984 and 1990 surveys, remained unchanged between 1990 and 1995. Separate analyses for each beverage type (beer, wine, and spirits) and most demographic subgroups revealed similar temporal patterns. CONCLUSIONS Alcohol consumption levels, declining since the early 1980s, may reach a minimum by the 21st century. Consumption levels should be monitored carefully over the next few years in the event that long-term alcohol consumption trends may be shifting.

Abstract
In 1997 the Addiction Research Foundation of Ontario and Canadian Centre on Substance Abuse released updated guidelines for low-risk alcohol consumption. This paper presents the scientific rationale behind this statement. Important comprehensive overviews on the consequences of alcohol use were studied. Formal meta-analyses on morbidity and mortality were examined wherever possible. Individual elements from similar guidelines were investigated for their scientific foundation. Limited original analyses defined risk levels by average weekly consumption. The evidence reviewed demonstrated that placing limits on both daily intake and cumulative intake over the typical week is justifiable for the prevention of important causes of morbidity and mortality. Gender-specific limits on weekly consumption were also indicated. In these updated guidelines intended for primary prevention, days of abstinence are not necessarily recommended. Intoxication should be avoided and abstinence is sometimes advisable. Available evidence does not strongly favour one alcoholic beverage over another for cardiovascular health benefits.
