The Role of Personalized Normative Feedback in the Efficacy of Brief Intervention Among Argentinian University Students: A Randomized Controlled Trial.

Background: Personalized Normative Feedback (PNF) aims to modify misperceptions about peer consumption that influence one's drinking. PNF is usually a component in Brief Interventions delivered to university students. Despite this, whether PNF contributes to improving the effect of brief interventions is unclear. Objectives: This randomized controlled trial aimed to determine the role of PNF as an active ingredient in a face-to-face motivational brief intervention. Results: Participants were students from an Argentinian university (n=806; M=20.14; SD=3.17; 63.2% women) who presented at least one binge drinking episode in the last 12 months. Students were randomly assigned to 1) a Brief Intervention, 2) a Brief Intervention with PNF, or 3) an evaluation-only control group. The follow-up was three months later. After controlling sex and age, General Linear Models showed that both the brief intervention and the brief intervention with PNF reduced the quantity and frequency of alcohol consumption, binge drinking, and alcohol problems compared to the control condition. No differences were found between the brief intervention and the brief intervention with PNF. Also, treating eight students with brief intervention and 10 with brief intervention with PNF was necessary to benefit one student. Conclusions: In conclusion, this study demonstrates that brief intervention reduces alcohol consumption among Latin American university students and that PNF might not be an active ingredient of its effectiveness in this population. However, PNF could benefit students with specific characteristics, like those who overestimate their peers' drinking, highlighting the need to study moderators of effectiveness further.

Efficacy of Brief Intervention for Alcohol Consumption during Pregnancy in Argentinean Women: A Randomized Controlled Trial.

INTRODUCTION: Although Brief Intervention (BI) has proven to reduce alcohol consumption during pregnancy in high income countries, there is no evidence from the Southern Cone of America. Thus, we conducted a study to assess BI efficacy among Argentinean pregnant women. METHOD AND MATERIALS: We collected data on pregnant women receiving prenatal care at the public health system in Mar del Plata, Argentina. Women with less than 26 weeks of gestation (n = 486) were randomized to brief advice (BA) or BI. Three months later they were re-assessed; women with more than 26 weeks of gestation constituted a screening only control group (SC) (n = 154). Self-reported quantity and frequency of alcohol consumption, frequency of binge drinking, and related problems after three months were used as outcomes. We performed generalized estimating equations and clinical significance analyses. Also, we obtained newborn health indicators from the city's health system database to use as objective outcomes. Women who did not participate in any of the three former conditions were randomly selected to constitute a non-screening control group (NSC) (n = 150). We compared objective outcomes among BI, BA, and NSC groups using the Wilcoxon rank test. RESULTS: In comparison with SC, BI and BA reduced alcohol consumption, without differences between the latter two. Newborns of women who received BI and BA had better health indicators compared with the NSC group. CONCLUSIONS: performing either a BI or BA reduces alcohol consumption among Argentinean pregnant women and might lead to healthier newborns.

Road traffic injury risk from alcohol and cannabis use among emergency department patients in Argentina.

Objective: To report the risk from alcohol, cannabis, and their combined use for non-fatal road traffic injuries for drivers, passengers, and pedestrians. Methods: Risk was estimated using the case-crossover method. Participants (N= 306) were injured patients from an emergency department in Mar del Plata, Argentina. Results: Alcohol use (OR= 6.78, CI 95% 3.75-12.25) as well as combined alcohol and cannabis use (OR= 7.05, CI 95% 1.16-42.73) significantly increased the risk of a road traffic injuries. Alcohol use increased the risk in both, women (OR= 8.87, CI 95% 2.69-29.21) and men (OR= 6.16, CI 95% 3.10-12.23); in those >30 years old (OR= 6.01, CI 95% 2.09-17.24) and those <30 years old (OR= 7.15, CI 95% 3.49-14.65). This last group also had an increased risk after combined alcohol and cannabis use (OR= 7.05, CI 95% 1.16-42.75). Both drivers (OR= 6.40, CI 95% 3.23-12.69) and passengers (OR= 13.83, CI 95% 2.87-66.42) had an increased risk after alcohol consumption. Conclusions: To our knowledge, these are the first estimates of the risk of having a road traffic injury after alcohol and cannabis consumption in one of the countries of the Southern Cone (Argentina, Chile, and Uruguay). These results highlight the urgent need to implement and enforce comprehensive alcohol control measures. Furthermore, given the global trend towards legalizing cannabis for recreational use, our results could also inform policymakers to enact or amend impaired driving laws.

Profiles of alcohol use disorder criteria: Help-seeking vs self-achieved remission in Argentinean hospital patients.

This study aimed to identify alcohol use disorder (AUD) criteria that better characterized those who seek treatment and those who recover on their own. We gathered data from help-seeking (HS) patients in an alcohol unit and compared them with self-achieved remission (SAR) patients. The best criteria to predict HS were psychological problems due to use, physical problems due to use, repeated attempts or desire to stop using, and not being able to stop drinking. The best criteria to predict SAR were tolerance, craving, hazardous use, much time spent, larger/longer use than intended, and role impairment. We discuss the impact of these results in current efforts to improve the accuracy of AUD diagnosis.

Alcohol consumption's attributable disease burden and cost-effectiveness of targeted public health interventions: a systematic review of mathematical models.

BACKGROUND: Around 6% of total deaths are related to alcohol consumption worldwide. Mathematical models are important tools to estimate disease burden and to assess the cost-effectiveness of interventions to address this burden. METHODS: We carried out a systematic review on models, searching main health literature databases up to July 2017. Pairs of reviewers independently selected, extracted data and assessed the quality of the included studies. Discrepancies were resolved by consensus. We selected those models exploring: a) disease burden (main metrics being attributable deaths, disability-adjusted life years, quality-adjusted life years) or b) economic evaluations of health interventions or policies, based on models including the aforementioned outcomes. We grouped models into broad families according to their common central methodological approach. RESULTS: Out of 4295 reports identified, 63 met our inclusion criteria and were categorized in three main model families that were described in detail: 1) State transition -i.e Markov- models, 2) Life Table-based models and 3) Attributable fraction-based models. Most studies pertained to the latter one (n = 29, 48.3%). A few miscellaneous models could not be framed into these families. CONCLUSIONS: Our findings can be useful for future researchers and decision makers planning to undertake alcohol-related disease burden or cost-effectiveness studies. We found several different families of models. Countries interested in adopting relevant public health measures may choose or adapt the one deemed most convenient, based on the availability of existing data at the local level, burden of work, and public health and economic outcomes of interest.

Epidemiology of alcohol consumption and related problems in Latin American countries: Contributions of psychology.

Alcohol consumption is the leading risk factor for morbi-mortality in many Latin American Countries. However, epidemiologic studies are relatively scarce. Among factors such as limited research capacity, disciplinary traditions and an emphasis on psychopathology within the field of psychology, have been postulated to account for this. The aim of this article is to review epidemiologic research on alcohol in Spanish Speaking Latin American Countries, and to measure the contribution of psychology to the field. A systematic search was performed in English and Spanish using regional and international data bases. We identified 269 articles. Most focused on consumption patterns in youth, with samples from a single school and using a variety of measures. With the exception of multinational efforts like Emergency Room Collaborative Alcohol Analysis Project or those supported by World Health Organization/Pan American Health Organization, studies reviewed reflected little cross country collaboration. Mexico accounted for most of the productivity, while many countries had very few or no articles. Most research was performed by health science researchers with a small contribution from psychology, but which increased significantly over time. The results of this review provide a broad identification of patterns regarding epidemiologic research on alcohol, and demonstrate the need for national scientific policies to promote research on public health topics.

Alcohol and Road Traffic Injuries in Latin America and the Caribbean: A Case-Crossover Study.

BACKGROUND: This study reports dose-response estimates for the odds ratio (OR) and population attributable risk of acute alcohol use and road traffic injury (RTI). METHODS: Data were analyzed on 1,119 RTI patients arriving at 16 emergency departments (EDs) in Argentina, Brazil, Costa Rica, Dominican Republic, Guatemala, Guyana, Mexico, Nicaragua, Panama, and Trinidad and Tobago. Case-crossover analysis, pair-matching the number of standard drinks consumed within the 6 hours prior to the RTI with 2 control periods (prior d/wk), was performed using fractional polynomial analysis for dose-response. RESULTS: About 1 in 6 RTI patients in EDs were positive for self-reported alcohol 6 hours prior to the injury (country range 8.6 to 24.1%). The likelihood of an RTI with any drinking prior (compared to not drinking) was 5 times higher (country range OR 2.50 to 15.00) and the more a person drinks the higher the risk. Every drink (12.8 g alcohol) increased the risk of an RTI by 13%, even 1 to 2 drinks were associated with a sizable increase in risk of an RTI and a dose-response was found. Differences in ORs for drivers (OR = 3.51; 95% CI = 2.25 to 5.45), passengers (OR = 8.12; 95% CI = 4.22 to 15.61), and pedestrians (OR = 6.30; 95% CI = 3.14 to 12.64) and attributable fractions were noted. Acute use of alcohol was attributable to 14% of all RTIs, varying from 7% for females to 19% for being injured as a passenger. CONCLUSIONS: The finding that the presence of alcohol increases risk among drivers and nondrivers alike may further help to urge interventions targeting passengers and pedestrians. Routine screening and brief interventions in all health services could also have a beneficial impact in decreasing rates of RTIs. Higher priority should be given to alcohol as a risk factor for RTIs, particularly in Latin America and the Caribbean.

Gender and Alcohol Use Disorders Diagnostic Criteria in Emergency Department Patients of Argentina.

BACKGROUND: Alcohol consumption and its related consequences are not equal for women and men, although related studies do not frequently include gender analysis. OBJECTIVE: Our aim was to characterize differences in endorsement of ICD-10 and DSM 5 alcohol use disorder (AUD) criteria by gender in an Argentinean emergency department population. METHODS: A probability sample of patients (N = 923) from the largest emergency department in the city of Mar del Plata, Argentina (44% were females, aged 16 to 86, M (SD) = 37.31(15.20) was collected. Using a structured questionnaire, diagnostic criteria for alcohol use disorders, alcohol consumption, and socio-demographic variables were obtained. Bivariate and multivariate analyses were used to assess differences in the endorsement of each diagnostic criterion by gender. RESULTS: Women were less likely to endorse each of the criteria for each of the diagnostic schemes. Even after controlling alcohol consumption, socio-demographic variables, severity of alcohol use disorders and adjusting for multiple comparisons females had a lower probability than males of endorsing withdrawal and impaired control. CONCLUSIONS: gender differences in the endorsement of diagnostic criteria for both the DSM 5 and ICD-10 were found. Some differences in endorsement but not all, might be partially explained by alcohol consumption patterns and socio-demographic factors, and same remained after controlling severity of the AUD. Results also suggest a differential functioning of DSM 5 and ICD-10 AUD criteria for women and men.

[Alcohol consumption before and during pregnancy in Argentina: prevalence and risk factors]. / Consumo de alcohol antes y durante la gestación en Argentina prevalencia y factores de riesgo.

OBJECTIVE: Describe alcohol consumption by Argentine women before and during pregnancy and identify the factors associated with consumption- and pregnancy-related changes. METHODS: Cross-sectional observational study. Women were interviewed after giving birth and receiving care at two perinatal health care centers in Santa Fe, Argentina. Sociodemographic information, data on their alcohol use, and other information were obtained from the participants. A descriptive analysis of consumption prevalence rates was made and the factors associated with patterns of alcohol use were identified by means of repeated measure analysis. RESULTS: Of the 614 participants, 75.2% had had at least one alcoholic drink (standard unit) during pregnancy and 83.3% had done so in the previous year; 15.1% admitted having at least one episode of binge drinking (five or more drinks) during pregnancy and 27.6% in the year prior to pregnancy. Only 30.6% of the women said they had made any change in consumption during the previous year; of those, 55.6% reduced their consumption and 41.8% stopped drinking. Women who consumed the most alcohol before and during pregnancy reported higher consumption by their partners, smoked, and had more permissive attitudes about alcohol use during pregnancy. CONCLUSIONS: A specific prevention plan is required in Argentina to reduce alcohol use in pregnant women, adjusted to local patterns of use, with interventions that include couples, and focused on the youngest women, those who use tobacco, and those who have more permissive attitudes about alcohol use.

Alcohol intake and risk of injury.

Injuries constitute a leading cause of morbidity and mortality in the world, with intentional injuries and those related to traffic most important, due to their social impact and high prevalence. Although alcohol consumption has been identified as a risk factor for injuries, few studies have assessed risk separately for intentional injuries and unintentional injuries caused by traffic, and by other causes. The objective of this paper was to estimate the risk of injuries after acute alcohol consumption for intentional injuries and unintentional traffic and non-traffic injuries, using, alternatively, two exposure measures: self-reported drinking prior to the event and blood alcohol concentration. A probability sample was collected of 540 patients from the emergency department of a hospital in Argentina. Logistic regressions were performed, with and without adjusting for gender, age and drinking pattern. Higher risks were found when blood alcohol concentration was used as a measure of consumption, compared to self-report. The highest risk estimates were obtained for intentional injuries, followed by unintentional traffic and, lastly, by unintentional non-traffic injuries. After controlling for confounders, risks for intentional and unintentional traffic injuries appeared similar for those above and below the legal limit. Results point to a significant involvement of alcohol in the regional context.

Alcohol as a trigger for medical emergencies.

In this paper, our goal is to report relative risks of the impact of alcohol consumption 6 hours prior to medical emergencies presenting in the emergency department for 8,346 patients in seven countries using data from the Emergency Room Collaborative Alcohol Analysis Project. We found that alcohol increased the risk of a medical emergency by 2.17 times (confidence interval: 1.78-2.65), and those without a regular pattern of heavy drinking and those younger showed a greater risk. Acute alcohol is associated not only with injury but also with medical emergencies. More studies are needed on the acute role of alcohol in medical emergencies, preferably with data on the type of medical emergencies.

Threshold and optimal cut-points for alcohol use disorders among patients in the emergency department.

BACKGROUND: Current research suggests that Diagnostic and Statistical Manual of Mental Disorder (DSM)-IV alcohol abuse and dependence form a unidimensional continuum in emergency department (ED) patients in 4 countries: Argentina, Mexico, Poland, and the United States. In this continuum of alcohol use disorder (AUD), there are no clear-cut distinctions between the criteria for dependence and abuse in the severity dimension based on prior results from item response theory (IRT) analysis. Nevertheless, it is desirable to find a threshold for identifying cases for clinical practice and cut-points of clinical utility in this continuum to distinguish between patients more or less affected by an AUD, using a scale of symptoms count. METHODS: Data from 5,193 patients in 7 ED sites in the same 4 countries (3,191 current drinkers) were used to study the structure, threshold, and possible cut-points for the diagnoses of AUD. RESULTS: The proposed changes in the DSM-V, dropping the abuse item "legal problems" and adding an item on "craving," did not impact the IRT performance and unidimensionality of AUD in this sample. With a total set of 11 items (deleting "legal problems" and adding "craving" to the current set of DSM criteria), an endorsement of 2 or more criteria can be used as the threshold to define those with an AUD in clinical practice. Furthermore, we can distinguish at least 2 levels of clinical severity, 2 to 3 criteria (moderate), and 4 or more criteria (severe). CONCLUSIONS: A dimensional approach to AUD using the proposed new set of criteria for the DSM-V can be used to propose a threshold and levels of severity. More research in different populations and countries is needed to further substantiate a threshold and cut-points that could be used in new formulations of substance use disorders.

Alcohol industry, corporate social responsibility and country features in Latin America.

INTRODUCTION AND AIMS: Research on corporate behaviour can contribute to the understanding of the possible adverse impacts of alcohol-industry corporate social responsibility (CSR) initiatives and their potential influence on policymaking. This study explores the association between alcohol-industry CSR activities and selected country features in Latin America and the Caribbean. DESIGN AND METHODS: Nine health experts evaluated 148 CSR activities using a standardised protocol; activities were classified into the categories risk management CSR (rmCSR), that is, to avoid/rectify externalities (n = 67), and strategic CSR, that is, to fulfill philanthropic responsibilities (n = 81). We evaluated the associations, separately, between the number of rmCSR and of strategic CSR actions in each country with threats from public health measures (specifically, the level of research into alcohol consumption and harms, the existence of an alcohol surveillance system and the number of governmental alcohol policy actions) and per capita alcohol consumption; we adjusted by economic indices (country income level and the gross domestic product) and population size. RESULTS: Multivariate analyses showed that the higher the level of alcohol research within a country and its per capita consumption, the more likely rmSCR activities were to occur, independently of the country's economic development or population. DISCUSSION AND CONCLUSIONS: Results suggest rmSCR actions could be implemented as a way to preserve markets by counteracting scientific evidence about alcohol related harms. This evidence could serve as a starting point to future research, contributing to the understanding of alcohol industry behaviour and the advancement of effective public policies.

The relationship between self-reported drinking and BAC level in emergency room injury cases: is it a straight line?

BACKGROUND: While the validity of self-reported consumption based on blood alcohol concentration (BAC) has been found to be high in emergency room (ER) samples, little research exists on the estimated number of drinks consumed given a BAC level. Such data would be useful in establishing a dose-response relationship between drinking and risk (e.g., of injury) in those studies for which the number of drinks consumed is not available but BAC is. METHODS: Several methods were used to estimate the number of drinks consumed in the 6 hours prior to injury based on BAC obtained at the time of ER admission of n = 1,953 patients who self-reported any drinking 6 hours prior to their injury and who arrived to the ER within 6 hours of the event, from the merged Emergency Room Collaborative Alcohol Analysis Project (ERCAAP) and the World Health Organization Collaborative Study on Alcohol and Injury across 16 countries. RESULTS: The relationship between self-reported consumption and averaged BAC within each consumption level appeared to be fairly linear up to about 7 drinks and a BAC of approximately 100 mg/dl. Above about 7 reported drinks, BAC appeared to have no relationship with drinking, possibly representing longer consumption periods than only the 6 hours before injury for those reporting higher quantities consumed. Both the volume estimate from the bivariate BAC to self-report relationship as well as from a Widmark calculation using BAC and time from last drink to arrival to the ER indicated a somewhat weak relationship to actual number of self-reported drinks. CONCLUSIONS: Future studies may benefit from investigating the factors suspected to be driving the weak relationships between these measures, including the actual time over which the reported alcohol was consumed and pattern of drinking over the consumption period.

The Association Between Early Drinking and Dependence Varies by Drinking Context.

Evidence regarding the association between early drinking (ED) and later dependence is controversial. It has been alternately hypothesized that ED either plays a causal role in the development of dependence or that it is an early marker of increased psychosocial vulnerabilities. Despite a clear rationale for delaying youth consumption, it is important to discern this relationship. However, most epidemiological evidence comes from individual studies and high-income countries. If there is a causal link between ED and dependence, an association at the aggregate level would be expected. Furthermore, if the link is due to biological mechanisms, the association should be rather invariable regardless of the drinking context, while if the association is due to psychosocial factors, a wider variability is to be expected. We explored whether the association between ED and dependence varied across countries clustered by their shared contextual drinking characteristics. We used data from 169 countries from the Global Information System on Alcohol and Health of the World Health Organization: ED, alcohol dependence, heavy episodic drinking (HED), actual drinkers, and alcohol policy. To cluster countries by their shared drinking characteristics (prevalences of HED and actual drinkers, and alcohol policy), we used, sequentially, two multivariate data reduction techniques: a multiple correspondence analysis (MCA) and a hierarchic classification. To estimate the association between ED and alcohol dependence, beta regressions were performed, and then adjusted by country income-level and repeated by gender. The results indicated four country clusters: primarily abstainers (class 1), low drinking countries (class 2), high drinking countries (class 3), and very high drinking countries (class 4). Positive relationships between ED and alcohol dependence were found for all the countries in the world and for those in classes 1 and 2. No significant relationships were found for class 3 or class 4. These results were similar for males, but not for females, where no significant relationships were found after adjusting for income level. The association between ED and dependence varies according to the drinking context. Our findings either suggest that the ED-dependence association may be due to individual or environmental vulnerabilities that promote consumption outside cultural norms or that, if there is a causal link between ED and dependence, it is strongly moderated by psychosocial characteristics.

A Multilevel Model of Alcohol Outlet Density, Individual Characteristics and Alcohol-Related Injury in Argentinean Young Adults.

OBJECTIVES: Previous research from high-income countries has consistently shown an association between alcohol-related harms and neighborhood characteristics such as alcohol outlet density, but this research has not been extended to middle- and low-income countries. We assessed the role of neighborhood characteristics such as alcohol outlet density, overcrowding and crime rates, and individual characteristics including gender, age, alcohol and marijuana use, and geographic mobility associated with alcohol-related injuries in university students in Argentina. METHODS: Data were collected from a randomized sample of students attending a national public university (n = 1346). Descriptive, bivariable, and multilevel logistic regression analyses were performed. RESULTS: In the final model, on-premises alcohol outlet density-but not off-premises outlet density, overcrowding or crime-was associated with past-year and lifetime alcohol-related injury (median odds ratio=1.16). At the individual level, quantity (odds ratio (OR)=1.05, 95% CI=(1.01, 1.10)) and frequency (OR=1.66, 95% CI=(1.41,1.97)) of alcohol consumption and age (OR=0.81, 95% CI=(0.74, 0.88)) were associated with past-year and lifetime alcohol-related injury. CONCLUSIONS: This study contributes to an area with a paucity of information from non-high-income countries, finding differences with previous literature.

OBJECTIFS: Des recherches antérieures menées dans des pays à revenu éléve ont constamment montré une association entre les méfaits liés à l'alcool et les caractéristiques du quartier telles que la densité des points de vente d'alcool, mais cette recherche n'a pas été étendue aux pays à revenu moyen et faible. Nous avons évalué le rôle des caractéristiques du quartier telles que la densité des points de vente d'alcool, la surpopulation et les taux de criminalité, et les caractéristiques individuelles, y compris le sexe, l'âge, la consommation d'alcool et de marijuana, et la mobilité géographique associée aux blessures liées à l'alcool chez les étudiants universitaires en Argentine. MÉTHODES: Les données ont été recueillies auprès d'un échantillon aléatoire d'étudiants fréquentant une université publique nationale (n=1 346). Des analyses de régression logistique descriptives, bivariables et multiniveaux ont été effectuées. RÉSULTATS: Dans le modèle final, la densité des points de vente d'alcool sur place - mais pas la densité des points de vente hors établissement, le surpeuplement ou la criminalité - était associée aux blessures liées a l'alcool au cours de la dernière année et au cours de la vie (rapport de cotes médian=1.16). Au niveau individuel, quantité (OR=1.05, IC à 95%=(1.01, 1.10)) et fréquence (OR=1.66, IC à 95%=(1.41,1.97)) de consommation d'alcool et âge (OR=0.81, 95% IC=(0.74, 0.88)) étaient associés à des blessures liées à l'alcool au cours de la dernière année et de leur vie entière. CONCLUSIONS: Cette étude contribue à un domaine où les informations sur les pays qui ne sont pas à revenu élevé sont rares, trouvant des différences avec la littérature précédente.

Evidence of DSM-5 and ICD-11 concurrent validity among Argentineansseeking treatment for alcohol use disorders / Evidencia de la validez concurrente del DSM-5 e ICD-11 en argentinos que buscan tratamiento por trastorno por uso de alcohol

Current efforts to better understand alcohol use disorder (AUD) have led to revisions of the most used classification systems, the DSM and the ICD. There is scarce information regarding how the latest versions of those two classification systems (DSM-5 and ICD-11) relate to functional characteristics (functional impairment (FI) and subjective distress (SD)) associated with AUD. Aim:To examine how the primary diagnostic system's criteria (DSM) and guidelines (ICD) were related to two functional characteristics (FI and SD) as evidence of these systems' concurrent validity in Argentineans with AUD. Methods:We conducted a cross-sectional correlational study with a clinical sample (n=34) in 2018. Results:AUD's severity was more strongly related to SD than FI. FI was weakly related to the criterion of much time spent usingit. We found weak associations between SD and role impairment, interpersonal problems, tolerance, and physical or psychological problems due to use, withdrawal, and much time spent using. Only one of the ICD guidelines was weakly related to SD, and we found moderate positive correlations between DSM-5 and FI and between DSM-5 and SD. Conclusion:DSM-5 was more accurate than ICD-11 in identifying those with higher levels of FI and SD and, thus, had a greater concurrent validity among a clinical sample of Argentineans with AUD. Our results contribute to a better understanding of the detection of alcohol-related conditions.

Los esfuerzos por comprender mejor el trastorno por uso de alcohol (TUA) han dado lugar a revisiones de los sistemas de clasificación más utilizados, el DSM y la ICD. Hay escasa información sobre cómo sus últimas versiones (DSM-5 y ICD-11) se relacionan con las características funcionales (deterioro funcional (DF) y angustia subjetiva (AS)) asociadas con el TUA. Objetivo: examinar cómo los criterios de los sistemas de diagnóstico se relacionaron con dos características funcionales (DF y AS) como evidencia de la validez concurrente en argentinos con TUA. Métodos: Realizamos un estudio correlacional-transversal con una muestra clínica (n= 34) en el año 2018. Resultados: La gravedad del AUD estuvo más fuertemente relacionada con la AS que con la DF. El DF se relacionó débilmente con el criterio mucho tiempo dedicado al uso. Se encontraron asociaciones débiles entre AS y deterioro de roles, problemas interpersonales, tolerancia y problemas físicos o psicológicos debido al uso, abstinencia y mucho tiempo dedicado al uso. Sólo una de las guías de la CIE estaba débilmente relacionada con la AS, y encontramos correlaciones positivas moderadas entre el DSM-5 y AS y entre el DSM-5 y DF. Conclusión: El DSM-5 fue más preciso que la CIE-11 para identificar a aquellos con mayores niveles de AS y DF y, por tanto, tuvo una mayor validez concurrente en la población observada. Estos resultados contribuyen a una mejor comprensión de la detección de las condiciones mentales relacionadas con el uso de alcohol.

Alcohol and violence in the emergency department: a regional report from the WHO collaborative study on alcohol and injuries.

OBJECTIVE: To determine the relative risk (RR) of non-fatal unintentional and violence-related injury associated with alcohol consumption in three emergency departments in Latin America (2001-2002). MATERIAL AND METHODS: Pair-matched case-crossover was used to obtain RR estimates for alcohol in non-fatal injuries among 447 patients in Argentina (A), 489 in Brazil (B) and 455 in Mexico (M). Intentional (violence) or unintentional (non-violence) injury status were the main outcomes. RESULTS: About 46% of violence-related cases involved alcohol (versus 11.5% for non-violence related cases). The risk of violence-related injury increased with drinking and had an OR= 15.0 (95% confidence interval (CI), 5.8-39.1), with an OR= 4.2 (CI= 2.7-6.5) for unintentional injuries. CONCLUSIONS: Increasing amounts of drinking may have pronounced consequences on the risk of triggering an injury, especially for a violence-related injury. The RR estimates provided here can be useful for new estimates on alcohol and the burden of disease.

Is the alcohol industry doing well by 'doing good'? Findings from a content analysis of the alcohol industry's actions to reduce harmful drinking.

OBJECTIVES: The aims of this study were to: (1) describe alcohol industry corporate social responsibility (CSR) actions conducted across six global geographic regions; (2) identify the benefits accruing to the industry ('doing well'); and (3) estimate the public health impact of the actions ('doing good'). SETTING: Actions from six global geographic regions. PARTICIPANTS: A web-based compendium of 3551 industry actions, representing the efforts of the alcohol industry to reduce harmful alcohol use, was issued in 2012. The compendium consisted of short descriptions of each action, plus other information about the sponsorship, content and evaluation of the activities. Public health professionals (n=19) rated a sample (n=1046) of the actions using a reliable content rating procedure. OUTCOME MEASURES: WHO Global strategy target area, estimated population reach, risk of harm, advertising potential, policy impact potential and other aspects of the activity. RESULTS: The industry actions were conducted disproportionately in regions with high-income countries (Europe and North America), with lower proportions in Latin America, Africa and Asia. Only 27% conformed to recommended WHO target areas for global action to reduce the harmful use of alcohol. The overwhelming majority (96.8%) of industry actions lacked scientific support (p<0.01) and 11.0% had the potential for doing harm. The benefits accruing to the industry ('doing well') included brand marketing and the use of CSR to manage risk and achieve strategic goals. CONCLUSION: Alcohol industry CSR activities are unlikely to reduce harmful alcohol use but they do provide commercial strategic advantage while at the same time appearing to have a public health purpose.

Alcohol Use Disorders in Argentinian Girls and Women 12 Months Before Delivery: Comparison of DSM-IV, DSM-5, and ICD-10 Diagnostic Criteria.

BACKGROUND: The evidence of important problems related to prenatal alcohol exposure has faced researchers with the problem of understanding and screening alcohol use in this population. Although any alcohol use should be considered risky during pregnancy, identifying alcohol-drinking problems (ADPs) could be especially important because women with ADPs could not benefit from a simple advice of abstinence and because their offsprings are subjected to a higher risk of problems related with prenatal alcohol exposure. In this context, we aim to study the prevalence and characteristics of ADPs in pregnant women, evaluating the performance of different diagnostic systems in this population. OBJECTIVES: The aims of the study were to describe the prevalence of ADPs obtained with the criteria of the Diagnostic and Statistical Manual of Mental Disorders in its fourth (DSM-IV) and fifth edition (DSM-5), and the International Classification of Diseases (ICD)-10, in Argentinean females aged 13 to 44 years, 12 months before delivery; to evaluate the level of agreement between these classification systems; and to analyze the performance of each diagnosis criterion in this population. METHODS: Data were collected through personal interviews of a probability sample of puerperal women (N = 641) in the city of Santa Fe (Argentina), between October 2010 and February 2011. Diagnoses compatible with DSM-IV, DSM-5, and ICD-10 were obtained through the Composite International Diagnostic Interview. Agreement among diagnostic systems was measured through Cohen kappa. Diagnosis criteria performance were analyzed considering their prevalence and discriminating ability (D value). RESULTS: Total ADP prevalence was 6.4% for DSM-IV (4.2% abuse and 2.2% dependence), 8.1% for DSM-5 (6.4% mild, 0.8% moderate, and 0.9% severe alcohol use disorder), and 14.1% for the ICD-10 (11.9% harmful use and 2.2% dependence). DSM-5 modifications improved agreement between DSM and ICD. The least prevalent and worst discriminating ability diagnostic criterion was "legal problems." The most prevalent and 1 of the best discriminating ability diagnostic criterion was '"health issues." CONCLUSIONS: DSM-IV and ICD-10 dependence prevalence was similar to that of previous studies in pregnant women, whereas abuse prevalence was surprisingly higher. Our results indicate a better performance of the DSM-5 alcohol use disorder category relative to the DSM-IV dual categorization. Nevertheless, the poor diagnostic performance of some DSM-5 criteria in this population could evidence their intercultural variability.
