The Swiss cohort study on substance use risk factors : findings of two waves

Aim: To summarize published findings in peer-reviewed journals of the first two waves of the Swiss Cohort Study on Substance Use Risk Factors (C-SURF), a longitudinal study assessing risk and protective factors of 5,987 young men during the phase of emerging adulthood (20 years at baseline, followed-up 15 months later). Methods: Included were 33 studies published until November 2014 focusing on substance use. Results: Substance use in early adulthood is a prevalent and stable behavior. The 12-month prevalence of nonmedical use of prescription drugs (10.6%) lies between that of cannabis (36.4%) and other illicit drugs such as ecstasy (3.7%) and cocaine (3.2%). Although peer pressure in the form of misconduct is associated with increased substance use, other aspects such as peer involvement in social activities may have beneficial effects. Regular sport activities are associated with reduced substance use, with the exception of alcohol use. Young men are susceptible to structural conditions such as the price of alcohol beverages or the density of on-premise alcohol outlets. Particularly alcohol use in public settings such as bars, discos or in parks (compared with private settings such as the home) is associated with alcohol-related harm, including injuries or violence. Being a single parent versus nuclear family has no effect on alcohol use, but active parenting does. Besides parenting, religiousness is an important protective factor for both legal and illegal substance use. Merely informing young men about the risks of substance use may not be an effective preventive measure. At-risk users of licit and illicit substances are more health literate, e. g., for example, they seek out more information on the internet than non-at-risk-users or abstainers. Discussion: There are a number of risk and protective substance use factors, but their associations with substance use do not necessarily agree with those found outside Europe. In the United States, for example, heavy alcohol use in this age group commonly takes place in private settings, whereas in Switzerland it more often takes place in public settings. Other behaviors, such as the nonmedical use of prescription drugs, appear to be similar to those found overseas, which may show the need for targeted preventive actions. C-SURF findings point to the necessity of establishing European studies to identify factors for designing specific preventive actions.

Are alcohol outlet densities strongly associated with alcohol-related outcomes? A critical review of recent evidence.

ISSUES: There have been reviews on the association between density of alcohol outlets and harm including studies published up to December 2008. Since then the number of publications has increased dramatically. The study reviews the more recent studies with regard to their utility to inform policy. APPROACH: A systematic review found more than 160 relevant studies (published between January 2009 and October 2014). The review focused on: (i) outlet density and assaultive or intimate partner violence; (ii) studies including individual level data; or (iii) 'natural experiments'. KEY FINDINGS: Despite overall evidence for an association between density and harm, there is little evidence on causal direction (i.e. whether demand leads to more supply or increased availability increases alcohol use and harm). When outlet types (e.g. bars, supermarkets) are analysed separately, studies are too methodologically diverse and partly contradictory to permit firm conclusions besides those pertaining to high outlet densities in areas such as entertainment districts. Outlet density commonly had little effect on individual-level alcohol use, and the few 'natural experiments' on restricting densities showed little or no effects. IMPLICATIONS AND CONCLUSIONS: Although outlet densities are likely to be positively related to alcohol use and harm, few policy recommendations can be given as effects vary across study areas, outlet types and outlet cluster size. Future studies should examine in detail outlet types, compare different outcomes associated with different strengths of association with alcohol, analyse non-linear effects and compare different methodologies. Purely aggregate-level studies examining total outlet density only should be abandoned. [Gmel G, Holmes J, Studer J. Are alcohol outlet densities strongly associated with alcohol-related outcomes?

Risk of All-Cause Mortality in Alcohol-Dependent Individuals: A Systematic Literature Review and Meta-Analysis.

BACKGROUND: Alcohol dependence (AD) carries a high mortality burden, which may be mitigated by reduced alcohol consumption. We conducted a systematic literature review and meta-analysis investigating the risk of all-cause mortality in alcohol-dependent subjects. METHODS: MEDLINE, MEDLINE In-Process, Embase and PsycINFO were searched from database conception through 26th June 2014. Eligible studies reported all-cause mortality in both alcohol-dependent subjects and a comparator population of interest. Two individuals independently reviewed studies. Of 4540 records identified, 39 observational studies were included in meta-analyses. FINDINGS: We identified a significant increase in mortality for alcohol-dependent subjects compared with the general population (27 studies; relative risk [RR] = 3.45; 95% CI [2.96, 4.02]; p < 0.0001). The mortality increase was also significant compared to subjects qualifying for a diagnosis of alcohol abuse or subjects without alcohol use disorders (AUDs). Alcohol-dependent subjects continuing to drink heavily had significantly greater mortality than alcohol-dependent subjects who reduced alcohol intake, even if abstainers were excluded (p < 0.05). INTERPRETATION: AD was found to significantly increase an individual's risk of all-cause mortality. While abstinence in alcohol-dependent subjects led to greater mortality reduction than non-abstinence, this study suggests that alcohol-dependent subjects can significantly reduce their mortality risk by reducing alcohol consumption.

Drinking locations and alcohol-related harm: Cross-sectional and longitudinal associations in a sample of young Swiss men.

BACKGROUND: Alcohol consumption--in particular drinking volume (DV) and risky single occasion drinking (RSOD)--has been related to a wide range of negative consequences and health problems. Previous studies also suggested that drinking in certain locations may be more strongly associated with the occurrence of alcohol-related harm than drinking in others. However, they were conducted in countries culturally and legally different from European countries and were limited to cross-sectional designs. This study investigates the cross-sectional and longitudinal associations of alcohol-related harm with DVs in different locations in a sample of young Swiss men. METHODS: A representative sample of 4536 young Swiss male drinkers completed baseline and 15-month follow-up questionnaires. These assessed DVs in 11 locations, alcohol-related harm (i.e. number of alcohol-related consequences and alcohol use disorder criteria) and frequency of RSOD. Cross-sectional and longitudinal associations of alcohol-related harm with DVs in each location were tested using regression models, with and without adjustment for frequency of RSOD. RESULTS: Both cross-sectional and longitudinal analyses showed significant positive associations between alcohol-related harm and DVs at friends' homes, in discos/nightclubs and in outdoor public places, when controlling for frequency of RSOD. In contrast, the contribution of DVs at one's own home and in restaurants was consistently not significant when adjusted for frequency of RSOD. When controlling for RSOD, associations between alcohol-related harm and DVs in bars/pubs, when playing sports, during other leisure activities, at cinemas/theatres, during sporting events, and during special events were not consistent between cross-sectional and longitudinal analyses. CONCLUSION: Results suggest that prevention interventions should not only target reducing the overall volume of alcohol consumed and the frequency of RSOD in general, but they should additionally focus on limiting alcohol consumption in outdoor public places, discos/nightclubs, and in friends' homes in particular, or at least on preventing harm occurring in these occasions.

Validation of French and German versions of a Perceived Neighborhood Social Cohesion questionnaire among young Swiss males, and its relationship with substance use

This study main purpose was the validation of both French and German versions of a Perceived Neighborhood Social Cohesion Questionnaire. The sample group comprised 5065 Swiss men from the "Cohort Study on Substance Use Risk Factors." Multigroup Confirmatory factor analysis showed that a three-factor model fits the data well, which substantiates the generalizability of Perceived Neighborhood Social Cohesion Questionnaire factor structure, regardless of the language. The Perceived Neighborhood Social Cohesion Questionnaire demonstrated excellent homogeneity (α = 95) and split-half reliability (r = .96). The Perceived Neighborhood Social Cohesion Questionnaire was sensitive to community size and participants' financial situation, confirming that it also measures real social conditions. Finally, weak but frequent correlations between Perceived Neighborhood Social Cohesion Questionnaire and alcohol, cigarette, and cannabis dependence were measured.

Alcohol and brief intervention for trauma victims

Objective:to describe the causes and severities of trauma in patients who met the criteria for alcohol abuse or dependence according to Mini International Neuropsychiatric Interview, and to display the pattern of alcohol consumption and subsequent changes one year after trauma.Methods:a transversal and longitudinal quantitative study carried out between November 2012 and September 2013 in the ED. Medical and nursing students collected blood samples, applied the J section of the Mini International Neuropsychiatric Interview (MINI) and submitted alcohol abusers and dependents to BI. One year after admission, patients were contacted and asked about their patterns of alcohol use and their reasons for any changes.Results:from a sample of 507 patients admitted to the ED for trauma, 348 responded to MINI, 90 (25.9%) being abusers and 36 (10.3%) dependent on alcohol. Among the abusers, the most frequent cause of injury was motorcycle accident (35.6%) and among the dependents it was predominantly interpersonal violence (22.2%). Positive blood samples for alcohol were identified in 31.7% of the abusers and 53.1% of the dependents. One year after trauma, 66 abusers and 31 dependents were contacted, and it was ascertained that 36.4% of the abusers and 19.4% of the dependents had decreased alcohol consumption. The main reported reason for the reduction was the experienced trauma.Conclusion:the motorcycle accident was the most common cause of injury. The detection of problematic alcohol use and implementation of BI are important strategies in the ED, however for alcohol abusers and dependents, BI was not the most reported reason for any changes in patterns of alcohol use.

Moderating effects of gender on the relationships among substance use and school outcomes /

The following study was a secondary analysis of data drawn from adolescents in South Western Ontario. The purpose of the study was to: examine the relationships among substance use and school outcomes, explore the relationships between gender and school outcomes, examine the moderating potential of gender on the substance useschool outcomes relationship, and to provide researchers and educators further knowledge of adolescent substance use behaviours. Many previous studies have failed to include the three most common substances used by adolescents (i.e., alcohol, tobacco, and marijuana). Furthermore, many studies have included only one school outcome instead of comparing several outcome variables. Moderated hierarchical regression was used to determine if gender moderated the substance use-school outcomes relationships. The dependent variables consisted of alcohol use, binge drinking, tobacco use, and marijuana use. Five measure of school outcomes were used as independent variables, including Grade Point Average, Positive School-role Behaviour, Negative School Behaviour, School Withdrawal, and School Misbehaviour. The results for this study indicated that substance use and gender were both predictors of all school outcome variables. Furthermore, gender was found to moderate 5 of the 25 substance use-school outcome relationships.

The impact of education on the use of breat self- examination among Canadian women

The purpose of this study was to examine the relationship between the level of education that Canadian women have and their use of breast self-examination (BSE). The secondary objective of this study was to do some exploratory research to measure how the demographic characteristics of these women, and the behaviours that they chose to participate in, might be associated to their use of BSE. This exploratory research was done to gain a better understanding of what kinds of lifestyle and behavioural factors are associated with the use of BSE, and how these factors impact on the relationship that education has on women's use of BSE. The data for the women in the sample were taken from the 1990 Population Health Survey, conducted by Statistics Canada. This survey included questions related to both the demographic characteristics of this population, and their behavioural choices in regards to various healthy lifestyle factors. Education was found to be significantly related to the use of BSE. Many of the demographic variables (age, income, marital status and language) were also found to be significantly related to the use of BSE. The behavioural variables (tobacco use, alcohol use) did not reflect such a strong relationship.

Attachment and alcohol : testing a motivational model of problem drinking /

The purpose of this study was to replicate and extend a motivational model of problem drinking (Cooper, Frone, Russel, & Mudar, 1995; Read, Wood, Kahler, Maddock & Tibor, 2003), testing the notion that attachment is a common antecedent for both the affective and social paths to problem drinking. The model was tested with data from three samples, first-year university students (N=679), students about to graduate from university (N=206), and first-time clients at an addiction treatment facility (N=21 1). Participants completed a battery of questionnaires assessing alcohol use, alcohol-related consequences, drinking motives, peer models of alcohol use, positive and negative affect, attachment anxiety and attachment avoidance. Results underscored the importance of the affective path to problem drinking, while putting the social path to problem drinking into question. While drinking to cope was most prominent among the clinical sample, coping motives served as a risk factor for problem drinking for both individuals identified as problem drinkers and university students. Moreover, drinking for enhancement purposes appeared to be the strongest overall predictor of alcohol use. Results of the present study also supported the notion that attachment anxiety and avoidance are antecedents for the affective path to problem drinking, such that those with higher levels of attachment anxiety and avoidance were more vulnerable to experiencing adverse consequences related to their drinking, explained in terms of diminished affect regulation. Evidence that nonsecure attachment is a potent predictor of problem drinking was also demonstrated by the finding that attachment anxiety was directly related to alcohol-related consequences over and above its indirect relationship through affect regulation. However, results failed to show that attachment anxiety or attachment avoidance increased the risk of problem drinking via social influence.

L’apport du capital social, familial, personnel et délinquant à l’explication de la relation entre alcool, drogues et violence chez les jeunes

Cette étude s’inscrit dans le cadre plus large des travaux menés par le groupe de recherche Drug, Alcool and Violence International (DAVI) qui cherche à préciser la nature des liens qui se tissent entre l’alcool, les drogues et la violence chez trois groupes de jeunes - étudiants, décrocheurs, contrevenants - des villes de Montréal, Toronto, Philadelphie et Amsterdam. Elle explore plus spécialement les dimensions du capital social, familial, individuel et délinquant comme étant des voies d’explication possibles de la relation constatée entre la consommation d’alcool et de drogues et la manifestation de gestes de violence chez les jeunes de la grande région montréalaise fréquentant le milieu scolaire secondaire. Trois objectifs spécifiques de recherche sont poursuivis soit : 1) déterminer, à travers une recension des écrits scientifiques, les modalités formant les dimensions du capital social, familial, individuel et délinquant; 2) cerner empiriquement dans les données, quelles sont les modalités à disposition permettant de rendre compte de la contribution du capital social, du capital familial, du capital individuel et du capital délinquant dans l’explication de la relation alcool/drogues et violence chez les jeunes; et 3) vérifier si les dimensions à l’étude influencent a) la consommation par les jeunes d’alcool et de drogues; b) la manifestation par eux de comportements délinquants, et plus spécialement de comportements violents, et c) la relation entre alcool, drogues et violence chez les jeunes fréquentant le milieu scolaire secondaire montréalais en fonction de ces dimensions. L’échantillon de type aléatoire est composé de 995 répondants (garçons et filles ) qui se répartissent dans huit écoles secondaires francophones et deux écoles secondaires anglophones provenant des secteurs public ou privé et de milieu favorisé ou défavorisé se trouvant sur les territoires des villes de Montréal, Laval et Longueuil constituant « la grande région de Montréal ». Les participants devaient répondre à un questionnaire composé de 138 questions dont la grande majorité sont fermées. Les données sociodémographiques caractérisant le jeune et son environnement, ses rapports avec sa famille, ses amis, l’école, son quartier, sa consommation d’alcool et de drogues, l’existence dans sa vie de comportements violents dont il aurait été auteur ou victime, la manifestation de gestes de délinquance ou de troubles de comportement sont les principales dimensions de la vie du jeune sondées par le questionnaire utilisé. D’entrée de jeu, spécifions que peu importe les substances consommées, très peu d’étudiants en font un usage problématique et que l’on ne note aucune propension à la délinquance chez la majorité des élèves de l’échantillon En somme, les analyses amènent à conclure à l’existence de relations statistiquement significatives entre la consommation d’alcool, de marijuana et de drogues dures et la propension à la délinquance et aux troubles de comportement, ces relations étant de force variable allant de modérée à forte. Toutefois, il faut bien noter que ces relations ne touchent qu’un petit nombre des élèves du secondaire participant à notre étude, comme ce fût le cas dans d’autres études. Plus spécifiquement, le capital familial paraît influencer seulement la consommation de marijuana. Ainsi, plus le degré de supervision parentale diminue, plus la fréquence de consommation de marijuana augmente. Le capital individuel produit un impact plus important sur la consommation d’alcool, de marijuana et de drogues dures, les troubles de comportement, et la propension à la délinquance. Ainsi, plus le capital individuel est affecté négativement, plus la consommation d’alcool, de marijuana et de drogues dures de même que la propension à la délinquance et aux troubles de comportement seront importants. Le capital social, quant à lui, explique davantage la consommation de marijuana que la consommation d’alcool et de drogues dures ou encore la manifestation de troubles de comportement et la propension à la délinquance. Finalement, le capital délinquant paraît influencer la consommation d’alcool, de marijuana et de drogues dures. Son influence se fait ressentir également, mais dans une moindre mesure, sur la manifestation de troubles de comportement et la propension à la délinquance. À notre grande surprise, la dimension du capital familial qui se révèle être particulièrement influente dans les écrits scientifiques ne ressort pas dans nos analyses comme nous l’avions envisagé. Nous attribuons cet état de fait aux limites imposées par l’utilisation d’une banque de données constituée initialement à d’autres fins que celles visées dans notre étude, et dans laquelle les facteurs reliés au capital familial, identifiés dans les écrits, n’étaient pas tous présents. Nul doute à que la consommation de substances psychoactives et la propension à la délinquance et aux troubles de comportement sont des comportements présents dans la population juvénile. Les modèles généralement utilisés pour expliquer les comportements déviants à l’étude ne produisent pas de résultats probants en ce qui concerne les écoliers, une population de jeunes d’ailleurs rarement étudiée à cet égard. Le modèle d’explication au cœur de nos analyses, mettant à contribution les dimensions du capital social, familial, individuel et délinquant, paraît prometteur surtout en ce qui concerne le capital délinquant, et ce, en dépit des limites imposées par la banque de données utilisée. À la lumière des résultats obtenus, il semble que l’explication de la cooccurrence de la consommation de substances psychoactives et de la propension à la délinquance et aux troubles de comportement soit multifactorielle. Les principaux facteurs contributifs sont ceux du capital délinquant pour la consommation d’alcool, de marijuana et de drogues dures de même que pour la propension à la délinquance alors les troubles de comportement se révèlent davantage expliqués par les facteurs composant le capital individuel. Nous estimons que la combinaison des dimensions du capital familial, individuel, social et individuel constitue une voie d’explication prometteuse de la relation alcool/drogue et violence chez les jeunes. Il nous apparaît dès lors qu’un instrument de collecte de données spécifiquement conçu pour en explorer le potentiel explicatif devrait être à la base de prochaines recherches en ce sens.

Patrons de consum d'alcohol en estudiants universitaris

L’objectiu general d’aquesta tesi és conèixer la prevalença i el patró de consum d’alcohol d’una mostra de 2,137 estudiants de la Universitat de Girona (17-35 anys). S’utilitzà un disseny multimètode integrant la metodologia quantitativa (estudi d’enquesta) amb la metodología qualitativa (grups focals). Un 65% dels joves són consumidors habituals d’alcohol. La influència social de pares, germans i amics és una variable crucial en la iniciació i manteniment del consum d’aquesta droga. El consum habitual és més freqüent entre aquells que van experimentar més precoçment amb la substància. Entre els homes és més habitual el consum massiu, però més dones efectuen consums considerats d’alt risc. Els joves reconeixen algunes repercussions socials de l’abús de l’alcohol però no en perceben per a la salut física. Aquests resultats mostren la necessitat de: endarrerir l’edat de primera experimentació, informar del risc del consum d’alcohol i fomentar un oci nocturn alternatiu i saludable.

Relations between Depression, Alcohol and Gender in the Metropolitan Region of São Paulo, Brazil

Como parte do projeto GENACIS, este artigo visou estimar a prevalência de depressão em amostra urbana de São Paulo, Brasil, assim como a associação entre depressão e padrão de uso de álcool segundo gênero. Para tanto, foi realizado inquérito epidemiológico com amostra probabilística e por conglomerados, com um total de 2083 adultos. Utilizou-se o CIDI SF para identificação de depressão. A análise estatística utilizou o teste de Rao Scott e regressão logística multivariada. A taxa de resposta foi de 74,9%. Predominaram mulheres (58,8%), menores de 40 anos de idade (52%). A prevalência de depressão foi de 28,3% para as mulheres e 12,7% para os homens. Entre os homens, 61,1% são de bebedores no último ano e a depressão esteve associada ao padrão de consumo de álcool, à maior frequência de binge drinking e à presença de problemas decorrentes do álcool. Entre as mulheres, 69,5% são abstinentes e a depressão se associou à convivência com cônjuge com problemas devidos ao álcool. Os resultados ressaltam que a associação entre depressão e consumo de álcool é distinta entre os gêneros.

Alcohol and Quality of Life Among Social Groups for the Elderly in Sao Jose dos Campos, Brazil

This study aims to investigate alcohol consumption within social groups for the elderly in So Jos, dos Campos-Brazil, and to check for a correlation between alcohol consumption and quality of life. A sample of 500 individuals participating on social groups for the elderly were interviewed by using the Alcohol Use Disorders Identification Test (AUDIT) to verify alcohol consumption; the Medical Outcomes Study 36 Item Short Form (SF-36), for evaluating quality of life; and the Oral Health Impact Profile short form (OHIP-14), for evaluating oral health-related quality of life. The average alcohol consumption was very low (1.48), being higher in men (2.23) than women (1.09). The SF-36 average score for the domain of physical function was 70.5; for role-physical function 64.9; for bodily pain,68.3; for general health 73.8; for vitality,72.4; for social function 82.8; for role-emotional function 72.3 and for mental health 75.0. The OHIP-14 average score was 3.87. AUDIT did not correlate with SF-36 domains, or with OHIP-14. However, there was a negative correlation between OHIP 14 and all SF-36 domains. This elderly sample has a very low consumption of alcohol, and no correlation was found between alcohol consumption and oral and medical quality of life.

Condutas de risco em jovens mulheres: álcool e sexo não seguro, temas necessários na formação de professores

The youth has been calling attention due to the large number of social problems resulting from the risky behaviors. One of the behaviors that stand out is the use of alcohol because, besides being the first drug to be used by children and adolescents, this population begins to use increasingly early. Another behavior that is becoming concern in that particular group, also with early start, is the unprotected sex, causing problems as the unplanned pregnancy, abortions and sexually transmitted diseases. However, one factor is becoming relevant and requiring further study, the number of young women developing sexually transmitted diseases and becoming risk drinkers. In this direction, this study has as objective to discuss the high number of alcohol use among young women, the vulnerability that this use causes for the unprotected sex and the importance of these subjects teachers training. It should be noted, finally, the lack of training of teachers to work with the thematic ones, and mainly, the need to deconstruct gender stereotypes, an obstacle in preventing the use of alcohol, other drugs and sexually transmitted diseases.

Validity of alcohol screening instruments in general population gender studies: an analytical review

The present study is an analytical review of the methodology used in studies of efficacy of screening instruments to detect harmful use/ alcohol dependence according to the gender in population surveys. Systematic review of bibliography was done, using data from Web of Science, Pubmed and PsycInfo. Population studies were included without date range, in English, Spanish or Portuguese languages, with sample of adults, evaluating psychometric characteristics of any alcohol screening instrument, whereas studies in special population or under treatment as well as prevalence of alcohol consumption were excluded. Thirteen studies were selected to be included in the present review. According to the studies, the instruments that presented a better performance among men were AUDIT and its derivatives (6 studies) and CAGE (2 studies), whereas among women, AUDIT and its derivatives (7 studies), followed by CAGE (3 studies). The increase of consumption and problems related to alcohol use and its implications for public health indicate the need and urgency for adequacy of screening instruments to differences of gender in general population. The population surveys in the area are scarce. Furthermore, the found studies present heterogeneous methodology which makes accurate comparisons difficult.
