Contextualising psychological distress among regular ecstasy users : the importance of sociodemographic factors and patterns of drug use

Introduction and Aims. Considerable concern has been raised about associations between ecstasy use and mental health. Studies of ecstasy users typically investigate varying levels of lifetime use of ecstasy, and often fail to account for other drug use and sociodemographic characteristics of participants, which may explain mixed findings. The current study aimed to examine the relationship between patterns of recent (last six months) ecstasy use and psychological distress among current, regular ecstasy users, controlling for sociodemographic risk factors and patterns of other drug use.

Design and Methods. Data were collected from regular ecstasy users (n = 752) recruited from each capital city in Australia as part of the Ecstasy and related Drugs Reporting System (EDRS). Psychological distress was assessed using the Kessler Psychological Distress Scale (K10). Data were analysed using multinomial logistic regression.

Results. Seven per cent of the sample scored in the ‘high’ distress category and 55% in the ‘medium’ distress category. Patterns of ecstasy use were not independently associated with psychological distress. The strongest predictors of distress were female sex, lower education, unemployment, ‘binge’ drug use including ecstasy (use for >48 h without sleep), frequent cannabis use and daily tobacco use.

Discussion and Conclusions. Regular ecstasy users have elevated levels of psychological distress compared with the general population; however, ecstasy use per se was not independently related to such distress. Other factors, including sociodemographic characteristics and other drug use patterns, appear to be more important. These findings highlight the importance of targeting patterns of polydrug use in order to reduce drug-related harm among regular ecstasy users

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.

How different is it really? – rural and urban primary students’ use of ICT in mathematics

Information and Communication Technology (ICT) offers the potential for changing mathematics education for both teachers and students. However, how ICT is used, and by whom, is critical to realizing this potential. This paper reports on an investigation of the use of ICT in the learning and teaching of mathematics in rural and urban primary schools in Victoria, Australia. Thirty-six teachers and almost 700 students were surveyed regarding their use of ICT for mathematics at home and at school, with a small number of selected teachers and students taking part in interviews. This paper focuses on students’ perceptions of ICT use. A comparison of rural and urban students’ responses shows little difference across most aspects of ICT use, and where there was a difference, the frequency of rural use almost always exceeded that in urban schools.

Vested interests in addiction research and policy alcohol industry use of social aspect public relations organizations against preventative health measures

Aim It has been proposed that alcohol industry ‘social aspects/public relations’ organizations (SAPROs) serve the agenda of lending credibility to industry claims of corporate responsibility while promoting ineffective industry-friendly interventions (such as school-based education or TV advertising campaigns) and creating doubt about interventions which have a strong evidence base (such as higher taxes on alcoholic beverages). This paper investigated whether submissions to Australia's National Preventative Health Taskforce (NPHT) from alcohol industry bodies regarding the Australian SAPRO, Drinkwise, have used this organization to demonstrate corporate responsibility while promoting industry-friendly interventions.

Method Submissions to the Australian National Preventative Health Taskforce (NPHT) discussion paper Australia, the healthiest country by 2020 (n = 375) were examined to identify those with primary alcohol content. A thematic analysis of the resulting 33 submissions was conducted to determine which organization, institution or individual discussed Drinkwise.

Setting Australia.

Findings Nine of the 33 submissions discussed Drinkwise; all were submitted by the alcohol industry or its affiliates. Every industry submission referred to Drinkwise either as providing evidence of social responsibility or by suggesting the industry-friendly actions of Drinkwise as alternatives to those recommended by the NPHT report.

Conclusions Drinkwise has been used by the alcohol industry to create an impression of social responsibility while promoting interventions that maintain profits and campaigning against effective interventions such as higher taxes on alcohol.

The growth performance of Jade Tiger cultured abalone fed diets supplemented with fish oil and vegetable oils

Background
The effects of fish oil (FO) supplementation and the dietary replacement of FO with flaxseed oil (FlaxO) and canola oil (CO) on the growth of cultured abalone was investigated. The study involved three growth experiments: (E1) diets containing 0.5, 1.0, 1.5, 2.0 and 2.5% of FO, respectively; (E2) diets in which FO was serially replaced by 25, 50, 75 and 100% FlaxO, respectively; and (E3) diets in which FO was serially replaced by 25, 50, 75 and 100% CO, respectively.

Results
In Experiment 1, abalone fed a diet supplemented with 1.5% FO showed a significantly higher (121.2 ± 1.1 mg day−1) daily growth rate of weight (DGRw) compared to control (70.1 ± 1.71 mg day−1). In Experiment 2, abalone fed 1.5% FO diet and diets containing 25–75% FlaxO showed no significant differences in DGRw. The diet containing 100% FlaxO showed significantly lower (63.3 ± 6.7 mg day−1) DGRw. In Experiment 3, abalone fed diets containing 25% and 50% CO showed similar DGRw as those fed a 1.5% FO diet. The diet containing 75% and 100% CO showed significantly lower (63.7 ± 5.0 to 95.4 ± 5.1 mg day−1) DGRw.

Conclusion
Supplementation with 1.5% of dietary FO can improve growth performance in cultured abalone. It is feasible to replace 75% of dietary FO with FlaxO and 50% of dietary FO with CO, without negative effect on growth performance.

Researching maternal, neonatal and child health service use in rural and pastoralist Ethiopia: A key informant research approach

Like many nations in sub-Saharan Africa, Ethiopia has both a high neonatal mortality rate and maternal mortality ratio and is unlikely to meet Millennium Development Goals 4 and 5 by 2015. This working paper examines how Key Informant Research (KIR) in rural and pastoralist Ethiopia will identify facilitators and barriers to the use of maternal, neonatal and child health services. The methodology is informed by Participative Ethnographic Evaluation Research (PEER) and Key Informant Monitoring (KIM). Key Informant Research (KIR) training will provide research skills to Health Extension Workers (HEWs) and Non-government organisation (NGO) staff to enable them to develop research questions, collect data and participate in preliminary data analysis. This will enable the identification of strategies that improve the identification of risk, enhance early referral, increase access, affordability and acceptability of skilled birthing services in rural and pastoralist Ethiopia.

Development of an exposure database and surveillance system for use by practicing OSH professionals

This report summarizes the development of an occupational exposure database and surveillance system for use by health and safety professionals at Rocky Flats Environmental Technology Site (RFETS), a former nuclear weapons production facility. The site itself is currently in the cleanup stage with work expected to continue into 2006. The system was developed with the intent of helping health and safety personnel not only to manage and analyze exposure monitoring data, but also to identify exposure determinants during the highly variable cleanup work. Utilizing a series of focused meetings with health and safety personnel from two of the major contractors at RFETS, core data elements were established. These data elements were selected based on their utility for analysis and identification of exposure determinants. A task-based coding scheme was employed to better define the highly variable work. The coding scheme consisted of a two-tiered hierarchical list with a total of 34 possible combinations of work type and task. The data elements were incorporated into a Microsoft Access database with built-in data entry features to both promote consistency and limit entry choices to enable stratified analyses. In designing the system, emphasis was placed on the ability of end users to perform complex analyses and multiparameter queries to identify trends in their exposure data. A very flexible and user-friendly report generator was built into the system. This report generator allowed users to perform multiparameter queries using an intuitive system with very little training. In addition, a number of automated graphical analyses were built into the system, including ex posure levels by any combination of building, date, employee, job classification, type of contaminant, work type or task, exposure levels over time, exposure levels relative to the permissible exposure limit (PELS), and distributions of exposure levels. Both of these interfaces, allow the user to ''drill down'' or gradually narrow query criteria to identify specific exposure determinants. A number of other industrial hygiene processes were automated by the use of this database. Exposure calculations were coded into the system to allow automatic calculation of time-weighted averages and sample volumes. In addition, a table containing all the PELs and other relevant occupational exposure limits was built into the system to allow automatic comparisons with the current standards. Finally, the process of generating reports for employee notification was automated. The implementation of this system demonstrates that an integrated database system can save time for a practicing hygienist as well as provide useful and more importantly, timely information to guide primary prevention efforts.
