I don't know anyone that has two drinks a day : young people, alcohol and the government of pleasure

Problematic alcohol consumption is a major public health, health education and health promotion issue in Australia and internationally. In an effort to better understand young people's drinking patterns and motivations we investigated the cultural drivers of drinking in 14–24 year-old Australians. We interviewed 60 young people in the state of Victoria aged 20–24 about their drinking biographies. At the time of interviewing, the draft guidelines on low-risk drinking were released by the National Health and Medical Research Council, Australia, and we asked our participants what they knew about them and if they thought they would affect their drinking patterns. Their responses indicate that pleasure and sociability are central to young people's drinking cultures which is supported by a range of research. However, O’Malley and Valverde claim that pleasure is silenced and/or deployed strategically in neo-liberal governance discourses about drugs and alcohol such as these guidelines which raises questions about the limits of such discourses to affect changes in drinking patterns.

Family relationship quality and early alcohol use : evidence for gender-specific risk processes

Objective: Family characteristics (relationship quality, parental behaviors, and attitudes relating to alcohol use) are known to influence alcohol use in the mid-teen years, and there is evidence that family characteristics have different influences on mid-teen girls versus boys. This study examined child gender differences in the association of family relationship quality, parental disapproval of children's alcohol use, and parental alcohol use with early adolescent alcohol use.

Method: Grade 6 and 8 students (modal age 11 and 13, respectively; N = 6,837; 52.6% female) were recruited from 231 schools across three Australian states. Hypotheses were tested using two-level ordinal logistic regression (individuals nested within schools). The main dependent measure was lifetime frequency of early adolescent alcohol consumption. Independent variables included mother's/father's alcohol use, closeness, conflict, and disapproval of adolescent alcohol use. Control variables included sensation seeking, peer alcohol use, and socioeconomic disadvantage.

Results: The key findings were that for the young age group (Grade 6), emotional closeness to the parent of the opposite sex was protective. Family conflict was associated with females' drinking in both age groups but not males' drinking.

Conclusions: There was evidence of gender differences in the epidemiology of family relationship quality and early alcohol use. Social developmental models may need revision to account for these child gender differences. Gender-specific family dynamics may be an important consideration for family-oriented prevention strategy.

Influence of family factors and supervised alcohol use on adolescent alcohol use and harms : similarities between youth in different alcohol policy contexts

Objective: Harm-minimization policies suggest that alcohol use is a part of normal adolescent development and that parents should supervise their children's use to encourage responsible drinking. Zero-tolerance policies suggest that all underage alcohol use should be discouraged. This article compared hypotheses derived from harm-minimization and zero-tolerance policies regarding the influence of family context and supervised drinking on adolescent alcohol use and related harms among adolescents in Washington State, USA, and Victoria, Australia. two states that have respectively adopted zero-tolerance and harm-minimization policies.

Method: Representative samples of seventh-grade students (N = 1,945:989 females) were recruited from schools in each state. Students completed comprehensive questionnaires on alcohol use, related problem behaviors, and risk and protective factors annually from 2002 to 2004 when they were in ninth grade.

Results: Relationships between family context and alcohol use and harmful use were very similar in both states. Adult-supervised settings for alcohol use were associated with higher levels of harmful alcohol consequences. Adult-supervised alcohol use mediated the links between favorable parental attitudes to alcohol use and ninth-grade alcohol use for students in both states.

Conclusions: Despite policy differences in the two states, relationships between family context variables and alcohol use and harmful use are remarkably similar. Adult-supervised settings for alcohol use resulted in higher levels of harmful alcohol consequences, contrary to predictions derived from harm-minimization policy. Findings challenge the harm-minimization position that supervised alcohol use or early-age alcohol use will reduce the development of adolescent alcohol problems.

Gender differences in the impact of families on alcohol use : a lagged longitudinal study of early adolescents

Aims From the pre-teen to the mid-teen years, rates of alcohol use and misuse increase rapidly. Cross-sectional research shows that positive family emotional climate (low conflict, high closeness) is protective, and there is emerging evidence that these protective mechanisms are different for girls versus boys. The aim of this study was to explore gender differences in the longitudinal impact of family emotional climate on adolescent alcohol use and exposure to peer drinking networks.

Design Three-wave two-level (individual, within-individual over time) ordinal logistic regression with alcohol use in the past year as the dependent measure and family variables lagged by 1 year.

Setting Adolescents completed surveys during school hours.

Participants A total of 855 Australian students (modal age 10–11 years at baseline) participating in the International Youth Development Study (Victoria, Australia).

Measurements These included emotional closeness to mother/father, family conflict, parent disapproval of alcohol use and peer alcohol use.

Findings For girls, the effect of emotional closeness to mothers on alcohol use was mediated by exposure to high-risk peer networks. Parent disapproval of alcohol use was protective for both genders, but this effect was larger for boys versus girls, and there was no evidence that peer use mediated this effect. Peer drinking networks showed stronger direct risk effects than family variables.

Conclusions Family factors unidirectionally impact on growth in adolescent alcohol use and effects vary with child gender.

Effect of a commercial alcohol ethoxylate surfactant (C11–15E7) on biodegradation of phenanthrene in a saline water medium by Neptunomonas naphthovorans

Biodegradation of poorly soluble polycyclic aromatic hydrocarbons (PAHs) has been a challenge in bioremediation. In recent years, surfactant-enhanced bioremediation of PAH contaminants has attracted great attention in research. In this study, biodegradation of phenanthrene as a model PAHs solubilized in saline micellar solutions of a biodegradable commercial alcohol ethoxylate nonionic surfactant was investigated. The critical micelle concentration (CMC) of the surfactant and its solubilization capacity for phenanthrene were examined in an artificial saline water medium, and a type of marine bacteria, Neptunomonas naphthovorans, was studied for the biodegradation of phenanthrene solubilized in the surfactant micellar solutions of the saline medium. It is found that the solubility of phenanthrene in the surfactant micellar solutions increased linearly with the surfactant concentrations, but, at a fixed phenanthrene concentration, the biodegradability of phenanthrene in the micellar solutions decreased with the increase of the surfactant concentrations. This was attributed to the reduced bioavailability of phenanthrene, due to its increased solubilization extent in the micellar phase and possibly lowered mass transfer rate from the micellar phase into the aqueous phase or into the bacterial cells. In addition, an inhibitory effect of the surfactant on the bacterial growth at high surfactant concentrations may also play a role. It is concluded that the surfactant largely enhanced the solubilization of phenanthrene in the saline water medium, but excess existence of the surfactant in the medium should be minimized or avoided for the biodegradation of phenanthrene by Neptunomonas naphthovorans.

Effects of additives on the cloud points of selected nonionic linear ethoxylated alcohol surfactants

Effects of various additives including inorganic salts, nonionic and ionic surfactants, water-soluble polymers and alcohols on the cloud points of three linear nonionic surfactants, Tergitol 15-S-7, Tergitol 15-S-9 and Neodol 25-7, were investigated. These surfactants are readily biodegradable and either linear primary or secondary ethoxylated alcohols. Cloud points of these surfactants were functions of their concentrations and concentrations of additives. The cloud points of nonionic surfactant mixtures lay in between the cloud points of individual component surfactants. Presence of two ionic surfactants, sodium dodecyl sulfate (SDS) and cetyl trimethyl ammonium bromide (CTAB), increased the cloud point of 1 wt% Tergitol 15-S-7 micellar solution dramatically when concentrations of ionic surfactants approaching their critical micelle concentration. Addition of water-soluble polymers decreased the cloud point, while addition of inorganic salts can either increase or decrease the cloud points. However, the effect of an alcohol additive on cloud point was dependent on its chain length or its water solubility. Interestingly, synergistic effects between sulfate or phosphate and pentanol on depression of cloud points of Tergitol 15-S-9 were discovered. A linear model predicting cloud points of Tergitol 15-S-X (X = 7, 9 and 12) surfactants and Neodol 25-X (X = 7, 9 and 12) surfactants were proposed with a correlation to logarithm of their ethylene oxide numbers.

Key themes and research agendas in the sport-alcohol nexus

This article synthesizes the main themes and research agendas that have been explored in studies of sports-associated drinking. It identifies four themes in which sport and alcohol come together: (a) the commercial economy; (b) social practices and cultural identities; (c) crime and violence; and (d) health behaviors. The article highlights the paradoxical and contradictory nature of the sport-alcohol nexus, especially in relation to health behaviors and crime and violence, where sport is both a context for and a “solution” to health damaging and criminal behavior. The article also argues for the contribution that studies of sports-based drinking can make to the sociology of sport and alcohol use more broadly, particularly with regard to applying new theoretical perspectives such as “calculated hedonism” and “casual leisure” to drinking in sporting contexts. It also extends our analysis of the beer-sport-gender “holy trinity” to considering drinking by women as well as among less traditional forms of masculine identities.

Everyday risks and professional dilemmas : fieldwork with alcohol-based (sporting) subcultures

This article discusses some of the everyday risks and professional dilemmas encountered when conducting participant-observation based research into the use and meaning of alcohol among fans of Australian Rules football. The key risks and dilemmas were those that emerged from female researchers entering into a predominantly male football subculture in which alcohol is routinely (and often excessively) consumed, the negotiation of key gatekeepers, the potential dangers of conducting research with participants who are inebriated and the duty of care to research participants. The article draws on an eighteen-month period of ethnographic fieldwork to highlight the risks and dilemmas negotiated and re-negotiated throughout the research process. The article argues that a failure to attend to these and other risks and dilemmas can threaten the viability of research among drinking-based communities and subcultures.

Association of adolescent symptoms of depression and anxiety with alcohol use disorders in young adulthood : findings from the Victorian Adolescent Health Cohort Study

Objective: To examine the association of adolescent depression and anxiety symptoms with alcohol abuse or dependence in young adulthood.

Design, setting and participants: Cohort study of the health and wellbeing of adolescents and young adults in Victoria, assessed at 8 waves (periods) of data collection, from age 14 to 24 years, between 1992 and 2003. Young people who participated in the cohort study at least once during the six adolescent assessment points (conducted 6 months apart, from age 14 to 17 years), at least once during young adulthood and who were alive at Wave 8 (n = 1758).

Main outcome measure: Alcohol abuse or dependence assessed using the alcohol and substance abuse modules of the Composite International Diagnostic Interview at age 24 years.

Results: Adolescents with moderate to high levels of depression and anxiety symptoms (measured by the revised Clinical Interview Schedule) had an increased risk of alcohol abuse or dependence in young adulthood, compared with young adults with low levels of adolescent depression and anxiety symptoms, after adjusting for potential confounding factors. Risk was higher for those with symptoms at more than two adolescent assessment points (odds ratio [OR] 1.9; 95% CI, 1.7–2.0) and for those with symptoms at one or two assessment points (OR 1.3; 95% CI, 1.2–1.4), compared with those with no above-threshold symptoms in adolescence.

Conclusions: Adolescents with depression and anxiety symptoms are at increased risk for alcohol use disorders into young adulthood. They warrant vigilance from primary care providers in relation to alcohol use well into adulthood.

Association between 5-HTTLPR genotypes and persisting patterns of anxiety and alcohol use : results from a 10-year longitudinal study of adolescent mental health

The serotonin transporter gene (5-HTT) encodes a transmembrane protein that plays an important role in regulating serotonergic neurotransmission and related aspects of mood and behaviour. The short allele of a 44 bp insertion/deletion polymorphism (S-allele) within the promoter region of the 5-HTT gene (5-HTTLPR) confers lower transcriptional activity relative to the long allele (L-allele) and may act to modify the risk of serotonin-mediated outcomes such as anxiety and substance use behaviours. The purpose of this study was to determine whether (or not) 5-HTTLPR genotypes moderate known associations between attachment style and adolescent anxiety and alcohol use outcomes. Participants were drawn from an eight-wave study of the mental and behavioural health of a cohort of young Australians followed from 14 to 24 years of age (Victorian Adolescent Health Cohort Study, 1992 - present). No association was observed within low-risk attachment settings. However, within risk settings for heightened anxiety (ie, insecurely attached young people), the odds of persisting ruminative anxiety (worry) decreased with each additional copy of the S-allele (B30% per allele: OR 0.77, 95% CI 0.62–0.97, P¼0.029). Within risk settings for binge drinking (ie, securely attached young people), the odds of reporting persisting high-dose alcohol consumption (bingeing) decreased with each additional copy of the S-allele (B35% per allele: OR 0.74, 95% CI 0.64–0.86, Po0.001). Our data suggest that the S-allele is likely to be important in psychosocial development, particularly in those settings that increase risk of anxiety and alcohol use problems.

Early age alcohol use and later alcohol problems in adolescents : individual and peer mediators in a bi-national study

This paper examines whether there is cross-national similarity in the longitudinal relationship between early age alcohol use and adolescent alcohol problems. Potential mechanisms underlying this relationship also are examined, testing adolescent alcohol use, low self-regulation, and peer deviance as possible mediators. Students (N = 1,945) participating in the International Youth Development Study, a longitudinal panel survey study, responded to questions on alcohol use and influencing factors, and were followed annually over a 3-year period from 2002 to 2004 (98% retention rate). State-representative, community student samples were recruited in grade 7 in Washington State, United States (US, n = 961, 78% of those eligible; Mage = 13.09, SD = .44) and Victoria, Australia (n = 984, 76% of those eligible; Mage = 12.93, SD = .41). Analyses were conducted using multiple-group structural equation modeling. In both states, early age alcohol use (age 13) had a small but statistically significant association with subsequent alcohol problems (age 15). Overall, there was little evidence for mediation of early alcohol effects. Low self-regulation prospectively predicted peer deviance, alcohol use, and alcohol problems in both states. Peer deviance was more positively related to alcohol use and low self-regulation among students in Victoria compared to students in Washington State. The small but persistent association of early age alcohol use with alcohol problems across both samples is consistent with efforts to delay alcohol initiation to help prevent problematic alcohol use. Self-regulation was an important influence, supporting the need to further investigate the developmental contribution of neurobehavioral disinhibition.
