Alcohol consumption and gender in the 20th century: the case of Switzerland

Summary: Given the changes of gender roles in this century it is hardly justified to assume constant proportions of alcohol consumption for males and females. The purpose of the study was to reconstruct the consumption trends of males and females in Switzerland since the beginning of the 20th century. Cirrhosis mortality and survey data were used to disaggregate by sex the per capita alcohol consumption based on liver cirrhosis mortality suggests that the evolution of alcohol consumption in Switzerland followed a parallel course for both sexes only until the 1930 s. The low consumption during World War II and the evident increase until the beginning of the '60s seem to have resulted above all from the variations in consumption of beer by men. The decrease in total alcohol consumption observed since the '70s is also most probably due only to men; there is no indication of a decreasing consumption by women. The tendency of male and female consumption patterns to become more similar should be taken into account in the prevention of alcohol misus

Paradoxical Changes in Alcohol Consumption and CAGE Ratings Between 1996 and 2006 in the General Population of Geneva

Aims: To assess changes between 1996 and 2006 in alcohol use and dependence in the general population of Geneva, Switzerland. Methods: Postal surveys of alcohol consumption patterns in representative samples of the general population were compared. The four-item CAGE (Cut down, Annoyed, Guilty, Eye-opener) screener was used to estimate alcohol dependence. Results: There were 742 participants in 1996 (response rate 75%) and 1487 in 2006 (76%). The proportions of daily drinkers (1996: 18%; 2006: 10%; P14drinks/week) decreased between 1996 (13%) and 2006 (7%; P<0.001). However, decreases in heavy drinking were limited to men aged 30+ and women aged 30-49. The average number of drinks/week decreased from 6.4 in 1996 to 5.0 in 2006 (P<0.001). Perception of safe drinking levels decreased between 1996 (4drinks/day) and 2006 (3drinks/day, P<0.001). The prevalence of alcohol dependence, defined as a CAGE score ≥2, increased among women (1996: 6%; 2006: 14%; P=0.001), but not among men (1996: 18%, 2006: 19%). Two of the CAGE items were endorsed more frequently by women in 2006 than in 1996: ‘guilty' (1996: 9%; 2006: 15%; P=0.018) and ‘should cut down' (1996: 12%; 2006: 18%; P=0.04). Drinking and driving did not change significantly over time (2006: 21% of men, 9% of women). Conclusion: Alcohol consumption, heavy drinking and perceived levels of safe drinking decreased over these 10 years, but not drink driving or alcohol dependence. Paradoxically, alcohol dependence even increased among women, driven by CAGE items ‘guilty' and ‘should cut down', suggesting that changes in CAGE scores reflected changes in the social acceptability of drinking rather than changes in dependenc

Gait quality scoring data of Franches-Montagnes stallions at walk and trot on a treadmill by experts of the breed and their reliability

This article presents the data obtained from the scoring of 24 stallions of the Franches-Montagnes (FM) horse breed by six experts of this breed. The experts scored six traits at walk and eight at trot from the video recordings of these stallions walking and trotting on a treadmill during an incremental speed test. The scores were given on a scale of one to nine. All experts scored the same videos twice (two scoring tests) with a time interval of two years, and without feedback from the first scoring. Video sequences were presented in a different order between first and second scoring. The inter- and intra-rater reliability of the data was assessed using intraclass correlation coefficients (ICC) to evaluate its quality

Adolescent Drinking Patterns Across Countries: Associations with Alcohol Policies

Early consumption of full servings of alcohol and early experience of drunkenness have been linked with alcohol-related harmful effects in adolescence, as well as adult health and social problems. On the basis of secondary analysis of county-level prevalence data, the present study explored the current pattern of drinking and drunkenness among 15- and 16-year-old adolescents in 40 European and North American countries. Data from the 2006 Health Behavior in School Children survey and the European School Survey Project on Alcohol and other Drugs were used. The potential role of alcohol control and policy measures in explaining variance in drinking patterns across countries was also examined. Policy measures and data on adult consumption patterns were taken from the WHO Global Information System on Alcohol and Health, Eurostat and the indicator of alcohol control policy strength developed by Brand DA, Saisana M, Rynn LA et al. [(2007) Comparative analysis of alcohol control policies in 30 countries. PLoS Med 4:e151.]. We found that a non-significant trend existed whereby higher prices and stronger alcohol controls were associated with a lower proportion of weekly drinking but a higher proportion of drunkenness. It is important that future research explores the causal relationships between alcohol policy measures and alcohol consumption patterns to determine whether strict policies do in fact have any beneficial effect on drinking patterns, or rather, lead to rebellion and an increased prevalence of binge drinkin

The role of drunken older siblings and drunken peers in the alcohol-violence nexus

Background: It is common knowledge that alcohol use and violence in adolescence is interrelated. However, less is known about variables which modify the link between alcohol use and violent behaviours in adolescence. The present study investigates how the interaction of intraindividual [adolescent risky single occasion drinking (RSOD)], intrafamilial (risky drinking of older siblings) and extrafamilial (risky drinking among peers) alcohol-related risk factors contributes to adolescents' violence and delinquency. Methods: Multiple linear regression analyses including two- and three-way interactions were conducted based on a national representative sample of 3711 8-10th graders in Switzerland (mean age 15.0, SD = 0.95) who had older siblings. Results: All three alcohol-related risk factors and the three-way interaction contributed significantly to the frequency of violence and delinquency. Adolescents who frequently engage in RSOD and have both drunken peers and drunken older siblings had the highest levels of violence and delinquency. Moreover, their association between own drinking and violence increased the steepest. Conclusion: The present study confirmed the occurrence of cumulative risk processes and demonstrated that excessive alcohol consumption among older siblings and peers represents a crucial contextual factor for the link between adolescents' risky drinking and violence and delinquency. For prevention, the findings suggest that a focus on peers alone may not be effective if the familial background is not taken into consideratio

Brief alcohol interventions: Do counsellors' and patients' communication characteristics predict change?

Aims: To identify communication characteristics of patients and counsellors during brief alcohol intervention (BAI) which predict changes in alcohol consumption 12 months later. Methods: Tape-recordings of 97 BAI sessions with hazardous drinkers were analysed using the Motivational Interviewing Skill Code (MISC). Outcome measures were (i) baseline to a 12-month difference in the weekly drinking quantity, and (ii) baseline to a 12-month difference in heavy drinking episodes per month. Bivariate analyses were conducted for all MISC measures, and significant variables were included in multiple linear regression models. Results: Patient communication characteristics (ability to change) during BAI significantly predicted the weekly drinking quantity in the multiple linear regression model. There were significant differences for some of the counsellor skills in bivariate analyses but not in the multiple regression model adjusting for patients' talk characteristics. Changes in heavy drinking showed no significant association with patient or counsellor skills in the multiple linear regression model. Conclusion: Findings indicate that the more the patient expresses ability to change during the intervention, the more weekly alcohol use decreases. The role of the counsellor during the interaction, and influence on the outcomes was not clearly established. Implications for BAI and related research are discusse

Parents' alcohol use: gender differences in the impact of household and family chores

Background: Social roles influence alcohol use. Nevertheless, little is known about how specific aspects of a given role, here parenthood, may influence alcohol use. The research questions for this study were the following: (i) are family-related indicators (FRI) linked to the alcohol use of mothers and fathers? and (ii) does the level of employment, i.e. full-time, part-time employment or unemployment, moderate the relationship between FRI and parental alcohol use? Methods: Survey data of 3217 parents aged 25-50 living in Switzerland. Mean comparisons and multiple regression models of annual frequency of drinking and risky single occasion drinking, quantity per day on FRI (age of the youngest child, number of children in the household, majority of child-care/household duties). Results: Protective relationships between FRI and alcohol use were observed among mothers. In contrast, among fathers, detrimental associations between FRI and alcohol use were observed. Whereas maternal responsibilities in general had a protective effect on alcohol use, the number of children had a detrimental impact on the quantity of alcohol consumed per day when mothers were in paid employment. Among fathers, the correlations between age of the youngest child, number of children and frequency of drinking was moderated by the level of paid employment. Conclusion: The study showed that in Switzerland, a systematic negative relationship was more often found between FRI and women's drinking than men's. Evidence was found that maternal responsibilities per se may protect from alcohol use but can turn into a detrimental triangle if mothers are additionally in paid employmen

Young Swiss men's risky single-occasion drinking: Identifying those who do not respond to stricter alcohol policy environments

BACKGROUND Previous research has demonstrated a preventive effect of the alcohol policy environment on alcohol consumption. However, little is known about the heterogeneity of this effect. Our aim was to examine the extent of heterogeneity in the relationship between the strictness of alcohol policy environments and heavy drinking and to identify potential moderators of the relationship. METHODS Cross-sectional data from 5986 young Swiss men participating in the cohort study on substance use risk factors (C-SURF) were analysed. The primary outcome was self-reported risky single-occasion drinking in the past 12 months (RSOD, defined as 6 standard drinks or more on a single occasion at least monthly). A previously-used index of alcohol policy environment strictness across Swiss cantons was analysed in conjunction with 21 potential moderator variables. Random forest machine learning captured high-dimensional interaction effects, while individual conditional expectations captured the heterogeneity induced by the interaction effects and identified moderators. RESULTS Predicted subject-specific absolute risk reductions in RSOD risk ranged from 16.8% to - 4.2%, indicating considerable heterogeneity. Sensation seeking and antisocial personality disorder (ASPD) were major moderators that reduced the preventive relationship between stricter alcohol policy environments and RSOD risk. They also were associated with the paradoxical observation that some individuals displayed increased RSOD risk in stricter alcohol policy environments. CONCLUSION Whereas stricter alcohol policy environments were associated with reduced average RSOD risk, additionally addressing the risk conveyed by sensation seeking and ASPD would deliver an interlocking prevention mix against young Swiss men's RSOD

‘I DRINK SPIRITS TO GET DRUNK AND BLOCK OUT MY PROBLEMS ' BEVERAGE PREFERENCE, DRINKING MOTIVES AND ALCOHOL USE IN ADOLESCENCE

Aims: To investigate among adolescents whether (i) drinking motives are related to beverage preference; (ii) beverage preference is related to alcohol use (drinking levels and risky drinking occasions); (iii) the association between beverage preference and alcohol use is moderated or mediated by drinking motives. Method: Data from a national representative sample of 5379 8th-10th graders in Switzerland (mean age 15.1, SD = 0.95) were analysed using multiple regression analyses. Beverage preference was based on the proportion of a specific beverage in the total amount of drinks consumed at the last drinking occasion. Drinking motives were assessed by the drinking motive questionnaire revised (DMQ-R). Results: A significant positive association was found between enhancement motives and a preference for beer and spirits; the association was negative with regard to a preference for wine and alcopops. Conformity motives were positively related to a wine preference but negatively to a beer preference. Only a preference for beer and spirits was significantly associated with alcohol use in models that exclude motives. However, the association between beer preference and adolescent alcohol use was mediated by drinking motives. A preference for alcopops and spirits was moderated by motives: social drinkers who preferred alcopops drank less than those who did not prefer alcopops. Coping drinkers who preferred spirits drank more than those who preferred other alcoholic drinks. Conclusions: Drinking motives are potential explanatory factors for the association between beverage preference and alcohol use. Prevention approaches should target coping motives, particularly for adolescents who show a preference for spirit

Alcohol consumption and social inequality at the individual and country levels—results from an international study

Background: International comparisons of social inequalities in alcohol use have not been extensively investigated. The purpose of this study was to examine the relationship of country-level characteristics and individual socio-economic status (SES) on individual alcohol consumption in 33 countries. Methods: Data on 101 525 men and women collected by cross-sectional surveys in 33 countries of the GENACIS study were used. Individual SES was measured by highest attained educational level. Alcohol use measures included drinking status and monthly risky single occasion drinking (RSOD). The relationship between individuals' education and drinking indicators was examined by meta-analysis. In a second step the individual level data and country data were combined and tested in multilevel models. As country level indicators we used the Purchasing Power Parity of the gross national income, the Gini coefficient and the Gender Gap Index. Results: For both genders and all countries higher individual SES was positively associated with drinking status. Also higher country level SES was associated with higher proportions of drinkers. Lower SES was associated with RSOD among men. Women of higher SES in low income countries were more often RSO drinkers than women of lower SES. The opposite was true in higher income countries. Conclusion: For the most part, findings regarding SES and drinking in higher income countries were as expected. However, women of higher SES in low and middle income countries appear at higher risk of engaging in RSOD. This finding should be kept in mind when developing new policy and prevention initiative
