Which parents provide zero-alcohol beverages to adolescents? A survey of Australian parents' practices and intentions.

OBJECTIVE: Zero-alcohol beverages (<0.5% alcohol by volume) appear and taste similar to alcoholic beverages but are regulated similarly to soft drinks in many countries, blurring the distinction between alcoholic and non-alcoholic beverages. How parents view provision of zero-alcohol beverages to adolescents is likely a key determinant of adolescent consumption. We investigated factors associated with parents' provision of zero-alcohol beverages to adolescents, including attitudes toward zero-alcohol beverages and demographic, knowledge, and behavioural factors known to be associated with provision of alcoholic beverages. METHODS: We conducted an online cross-sectional survey of N = 1197 Australian parents of adolescents aged 12-17 years in April-May 2022. We examined associations with zero-alcohol beverage provision using binomial logistic regression, and with future provision intentions using multinomial logistic regression analyses. RESULTS: Factors significantly associated (p < .001) with parents' provision and future intentions to provide zero-alcohol beverages to their adolescent included beliefs that zero-alcohol beverages had benefits for adolescents (Adjusted Odds Ratio [AOR] 2.69 (provision); 3.72 (intentions)), provision of alcoholic beverages (AOR 2.67 (provision); 3.72 (intentions)), and an incorrect understanding of alcohol guidelines for adolescents (AOR 2.38 (provision); 1.95 (intentions)). CONCLUSIONS: Parents' provision and intentions to provide zero-alcohol beverages were associated with beliefs about zero-alcohol beverages as well as some factors associated with provision of alcoholic beverages. Precautionary advice to parents that the provision of zero-alcohol beverages may serve to normalise alcohol consumption may be warranted.

Personal and reported partner pornography viewing by Australian women, and association with mental health and body image.

Background Personal and partner pornography viewing may affect health and wellbeing. This study aimed to improve understanding of the effects of pornography on mental health and body image, given emerging evidence of increasing use, particularly among young people. METHODS: A cross-sectional survey was implemented, targeting people who had accessed health and fitness content via social media. Convenience sampling was used and participants were recruited via advertising on social media. RESULTS: Overall, 76% (75/99) of women reported having ever viewed pornography, and 21% had viewed pornography frequently (monthly/weekly/daily) in the prior 12 months. The association between frequent viewing and higher-risk Kessler 10 Psychological Distress Scale scores lost significance once controlled for age (adjusted OR 2.30, 95%CI 0.82-6.49, P=0.11). There was an association with frequent reported partner pornography use (monthly/weekly/daily) and increased Drive for Muscularity scores (adjusted OR 2.20, 95%CI 1.01-4.80, P=0.048). There were no other associations found with pornography use (personal or partner) and body image or mental health, although this was limited by the small sample size. Most women (85%, 41/48) reported being happy with their partner's pornography use, and in qualitative responses, indicated that pornography had minimal effect on their lives. Nevertheless, multiple qualitative responses indicated a multiplicity of perceived effects of pornography, including negative effects on body image. CONCLUSIONS: Pornography had a minor effect on mental health and body image in this study. Additional research is required to improve understanding of the effects of pornography on body image and mental health, particularly among vulnerable individuals.

Wagering Advertisements and Inducements: Exposure and Perceived Influence on Betting Behaviour.

A proliferation of wagering advertising has raised concerns about its effects, especially on vulnerable gamblers. This study examined exposure to wagering advertisements and inducements, and their reported influence on the size, frequency and riskiness of bets placed-amongst regular bettors and by gambler risk group. An Ecological Momentary Assessment design minimised recall bias. After completing a baseline survey, 722 regular bettors completed up to 15 surveys administered on 5 days per week over three non-consecutive weeks. Data were analysed for the 316 race bettors and 279 sports bettors completing at least one survey. The results indicate that regular bettors have almost daily exposure to wagering advertising, including for inducements. The most frequently seen and influential advertisement types were direct messages (emails, texts and/or phone calls from wagering operators, which, in Australia, bettors are automatically opted-into when opening a betting account) and advertisements on betting websites or apps. Participants reported the most influential inducements to be: stake-back offers, multi-bet offers, match your stake or deposit offers, better odds/winnings inducements, happy hours, rewards programs, and cash out early offers. The findings indicate that wagering advertisements, including for inducements, are likely to be having powerful effects on regular bettors. On each day that respondents saw these advertisements (most days for most advertisement types), substantial minorities reported increased size and frequency of betting. Results did not vary by gambler risk group. Understanding which types of wagering advertising are associated with most gambling-related harm can inform advertising regulations, targeted public health interventions, and future research.

Where's the Bonus in Bonus Bets? Assessing Sports Bettors' Comprehension of their True Cost.

Wagering inducements with bonus bets are prominently marketed and often have play-through conditions requiring further expenditure. However, these conditions are not usually presented in the inducement advertisement and may be difficult to locate. The play-through conditions themselves are complex and may lead bettors to miscalculate the inducement's true cost. Therefore, in relation to inducements with bonus bets, this study aimed to assess: (1) whether their perceived attractiveness varies with the amount and type of information provided about their play-through conditions; (2) bettors' comprehension of their true cost; and (3) whether bettors' comprehension of their true cost varies with problem gambling severity. A sample of 299 Australian sports bettors completed an online survey and rated the attractiveness of three variations of an inducement. Promo1 simply noted that "terms and conditions apply"; promo2 included the terms and conditions immediately below the offer; and promo3 revealed the true cost of the offer. Respondents were asked to calculate the true cost before this was revealed. The study found that detailing key terms and conditions for an offer directly below the advertisement impacts negatively on its perceived attractiveness. Moreover, nearly three in five bettors underestimated the additional amount they would need to bet to access any winnings from the bonus bet. No significant differences were found amongst gambler risk groups. The results imply that current approaches to marketing these inducements are likely to lead consumers to overestimate their attractiveness and underestimate their cost. To enhance responsible gambling practice, these promotional offers should be presented in ways that enable informed decision-making.

"I aspire to look and feel healthy like the posts convey": engagement with fitness inspiration on social media and perceptions of its influence on health and wellbeing.

BACKGROUND: Fitspiration is a popular social media trend containing images, quotes and advice related to exercise and healthy eating. This study aimed to 1) describe the types of fitspiration content that users access and how they engage with content, 2) investigate the disordered eating and exercise behaviours and psychological distress of individuals who access fitspiration, and 3) understand the perceived influence of fitspiration on health and wellbeing. METHODS: Participants who access fitspiration content were recruited via social media to complete a cross-sectional online survey. Participants' psychological distress was measured using the Kessler 10 Psychological Distress Scale (K10); disordered eating behaviours using the Eating Attitudes Test-26 (EAT-26); and compulsive exercise behaviours using the Exercise Addiction Inventory (EAI). Participants also answered a series of open-ended questions about their experiences with fitspiration. A descriptive statistical analysis was conducted for quantitative data. Responses to open-ended questions were analysed for key themes using an iterative process of open, axial and thematic coding. RESULTS: Participants (N = 180, 151 female, median age 23.0 years (IQR 19.0, 28.5)) most commonly accessed content posted by personal trainers and athletes (59.4%), posts tagged with the 'fitspiration' hashtag (53.9%) and posted by 'everyday' people (53.3%). Overall, 17.7% of participants were classified as high risk for an eating disorder, 17.4% reported very high levels of psychological distress, and 10.3% were at risk of addictive exercise behaviours. Participants described both positive and negative influences of engaging with fitspiration content. The influence on their health beliefs and behaviours was explained through four key themes: 1) Setting the 'healthy ideal', 2) Failure to achieve the 'ideal', 3) Being part of a community, and 4) Access to reliable health information. CONCLUSIONS: Many participants reported benefits of fitspiration content including increased social support and access to health information. However, participants also reported that fitspiration content could negatively influence their wellbeing and perception of healthy goals. Content posted by relatable individuals or qualified experts was perceived as most trustworthy. Future research is needed to determine the individual and content-related factors associated with negative and positive fitspiration experiences.

Investigating Differences Between Drugs Used in the Australian Night-Time Economy: Demographics, Substance Use, and Harm.

BACKGROUND: Understanding the characteristics of drug users in the night-time economy (NTE), and whether particular drugs are associated with risky practices and experience of harm, is necessary to inform targeted policy responses in this context. OBJECTIVES: To investigate the correlates of drugs used in the Australian NTE relating to demographics, alcohol use, and experience of harm. METHODS: Patrons were interviewed in the NTE of five Australian cities in 2012-2013 (n = 7,028; 61.9% male, median age 22 years). A custom designed survey gathered demographic data, alcohol, and substance use on the current night, and experience of harm in/around licensed venues in the past 3 months. Multivariate logistic regression analyses examined the correlates of drug use. RESULTS: Ecstasy was most commonly reported (4.0%), followed by cannabis (2.9%), methamphetamine (2.6%), and cocaine (1.6%). Ecstasy users were more likely to be younger and report energy drink consumption. Cannabis users were more likely to be male, and to have been involved in intoxication-related accidents/injuries and sexual aggression in/around licensed venues in the past 3 months. Methamphetamine users were more likely to have been interviewed later, and to have engaged in pre-drinking. Cocaine users were more likely to be male, aged 21 years or more, have a blood alcohol concentration of greater than 0.10%, and to have been involved in intoxication-related accidents/injuries in the past three months. Conclusions/Importance: We identified significant differences between types of drug users and the harms they experience, underscoring the need to develop innovative harm reduction policies in the NTE rather than blanket population-based approaches.

Is low BMI associated with specific drug use among injecting drug users?

Body mass index (BMI) of a sample of people who regularly inject drugs (N = 781) was examined to gauge the impact of specific types of drug use. Cross-sectional interviews were undertaken in 2010 as part of a national monitoring program funded by the Australian Government. Latent class analysis identified three groups of drug users, with heroin users at 3.4 times the risk of being underweight compared with amphetamine users, and amphetamine users were at almost twice the odds of being obese compared with lower level morphine users. Nutrition should play a part in harm minimization.

Harm from the drinking of people you know: A range of effects from different relationships.

AIMS: To describe the range of effects experienced due to the drinking of people respondents know and analyze risk and protective factors for harm from the drinking of partners and household members, other relatives and friends and co-workers. DESIGN, SETTING AND PARTICIPANTS: Surveys of 2574 participants' experiences were obtained from two samples: 1000 people responded to random digitally dialled Australian mobile calls and 1574 participants responded from the Life in AustraliaTM panel survey. MEASUREMENTS: Respondents were asked whether they had been negatively affected in the previous 12 months by the drinking of persons they knew who were 'a heavy drinker or drank a lot sometimes' and the nature of these harms. Weighted logistic regressions were used to analyze differences in rates of key negative outcomes from known others' drinking by gender, age and socio-economic status. FINDINGS: Almost two thirds [60.2%; 95% confidence interval (CI) = 57.7%-62.7%] of participants reported having heavy drinkers in their lives and 21.8% (95% CI = 19.8%-23.9%) reported being negatively affected by the drinking of people they knew well in some way. Participants reported a gamut of effects, including, most commonly, adverse social effects: having to transport relatives and friends who had been drinking, role failure and faults, being emotionally hurt or neglected, serious arguments, family problems, having to care for drinkers and verbal abuse. Less commonly, respondents reported physical or sexual harm, property damage, financial stress and threats from others' drinking. Women (odds ratio = 1.49; 95% CI = 1.13-1.95), younger people, rural, Australian-born (vs. respondents born overseas in non-English speaking countries) and more frequent drinkers were more likely to report harm from a drinker they knew than their counterparts after adjusting for other variables in the model. CONCLUSIONS: Australians appear to be commonly adversely affected by the drinking of people they know. Harms from known drinkers are more likely to be experienced by women than men, particularly from the people they live with and other relatives.

"They start on the zero-alcohol and they wanna try the real thing": Parents' views on zero-alcohol beverages and their use by adolescents.

OBJECTIVE: Zero-alcohol beverages containing 0.0-0.5% alcohol by volume may offer public health benefits if individuals use them to substitute for alcohol-containing products, thereby reducing alcohol use. There are, however, concerns that zero-alcohol beverages may encourage adolescents' earlier interest in alcohol and increase exposure to alcohol company branding. As this poses a challenge for parents, we studied parents' views on zero-alcohol beverages and their provision to adolescents. METHODS: We interviewed n=38 parents of 12-17-year-olds and used reflexive thematic analysis to interpret interview data. RESULTS: Parents considered zero-alcohol beverages to be 'adult beverages' that potentially supported reduced adult drinking but were unnecessary for adolescents. Parents were concerned that adolescent zero-alcohol beverage use could normalise alcohol consumption and be a precursor to alcohol initiation. There was a potential conflict between moderate provision in 'appropriate' contexts, and potential benefits, which were each supported by some parents. Uncertainty on health qualities was also reported. CONCLUSIONS: Parents reported conflicting and cautious views on zero-alcohol beverage provision to adolescents. IMPLICATIONS FOR PUBLIC HEALTH: As evidence on the impacts of zero-alcohol beverage availability develops, parent-targeted messages highlighting the potential risk of normalisation of alcohol use for young people could be developed, in conjunction with broader policy responses.

Establishing the Melbourne Injecting Drug User Cohort Study (MIX): rationale, methods, and baseline and twelve-month follow-up results.

BACKGROUND: Cohort studies provide an excellent opportunity to monitor changes in behaviour and disease transmission over time. In Australia, cohort studies of people who inject drugs (PWID) have generally focused on older, in-treatment injectors, with only limited outcome measure data collected. In this study we specifically sought to recruit a sample of younger, largely out-of-treatment PWID, in order to study the trajectories of their drug use over time. METHODS: Respondent driven sampling, traditional snowball sampling and street outreach methods were used to recruit heroin and amphetamine injectors from one outer-urban and two inner-urban regions of Melbourne, Australia. Information was collected on participants' demographic and social characteristics, drug use characteristics, drug market access patterns, health and social functioning, and health service utilisation. Participants are followed-up on an annual basis. RESULTS: 688 PWID were recruited into the study. At baseline, the median age of participants was 27.6 years (IQR: 24.4 years - 29.6 years) and two-thirds (67%) were male. Participants reported injecting for a median of 10.2 years (range: 1.5 months - 21.2 years), with 11% having injected for three years or less. Limited education, unemployment and previous incarceration were common. The majority of participants (82%) reported recent heroin injection, and one third reported being enrolled in Opioid Substitution Therapy (OST) at recruitment. At 12 months follow-up 458 participants (71% of eligible participants) were retained in the study. There were few differences in demographic and drug-use characteristics of those lost to follow-up compared with those retained in the study, with attrition significantly associated with recruitment at an inner-urban location, male gender, and providing incomplete contact information at baseline. CONCLUSIONS: Our efforts to recruit a sample of largely out-of-treatment PWID were limited by drug market characteristics at the time, where fluctuating heroin availability has led to large numbers of PWID accessing low-threshold OST. Nevertheless, this study of Australian injectors will provide valuable data on the natural history of drug use, along with risk and protective factors for adverse health outcomes associated with injecting drug use. Comprehensive follow-up procedures have led to good participant retention and limited attrition bias.

Alcohol's harm to others in 2021: Who bears the burden?

BACKGROUND AND AIMS: Alcohol's harm to others (AHTO) has become a key driver of national and international alcohol policy. This study aimed to produce a contemporary, comprehensive estimate of the correlates and harms from others' drinking in 2021 in Australia. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: Across Australia, 2574 adults (1380 women; 1172 men) were sampled via two cross-sectional survey modes: a random-digit dial mobile phone sample of 1000 people and 1574 people from the Life in Australia™ panel survey. In 2021 participants were asked about harms they had experienced from the drinking of family, friends, co-workers and the public in the past year. Applying combined sample weights from each mode, bivariable and adjusted multivariable logistic regressions were used to analyse differences in rates of AHTO by participant gender, age, residence in rural or metropolitan regions, country of birth, education and employment. FINDINGS: In 2021, 23.6% reported being negatively affected by strangers' drinking and 21.3% by the drinking of someone they knew, with 34.3% reporting being negatively affected a lot or a little by either; 42.4% of respondents reported specific harms from strangers' drinking. Thus, 48.1% of respondents reported any harm (negative effects or specific harms) from others' drinking. Women, younger people, Australian-born and heavier episodic drinkers reported significantly higher rates of AHTO compared with other respondents. Smaller percentages (7.5%) of participants reported being harmed substantially by others' drinking, including by people they knew (5.8%) or strangers (2.3%). Stratified analyses showed that heavier drinking, furloughed, younger men who were born overseas in English-speaking countries were affected by others' drinking, whereas women were affected regardless of these factors (apart from age). CONCLUSIONS: More than one-third of Australian adults appear to have been negatively affected by others' drinking in 2021, with women, younger people and heavier drinkers at greater risk. Substantial harm appears to be more likely to arise from the drinking of people Australians know than from strangers' drinking.

Modelling antiviral treatment to prevent hepatitis C infection among people who inject drugs in Victoria, Australia.

OBJECTIVES: To develop a mathematical model to project the potential impact of hepatitis C virus (HCV) treatment on HCV infection prevalence among people who inject drugs (PWID). DESIGN AND SETTING: An existing model of HCV transmission among PWID was parameterised using data from Victoria, Australia, including specific parameter estimates of the number of people who are currently active injecting drug users, average duration of injecting, chronic HCV infection prevalence among PWID, annual mortality, and annual HCV treatment rate. We also explored the impact of prevalence uncertainty, program scale-up, and new treatments. MAIN OUTCOME MEASURE: Prevalence of chronic HCV infection among people who are currently active injecting drug users. RESULTS: With annual treatment rates of 13, 17, or 25 per 1000 PWID, the model predicts relative prevalence reductions of 20%, 30%, and 50%, respectively, within 30 years. If new treatments giving higher sustained viral response rates are available in 5 years, estimated impact is increased by 21%­23% at 15 years, and 17%­38% at 30 years, depending on treatment rates. CONCLUSIONS: This model suggests that modest rates of current HCV treatment among PWID in Victoria, Australia could halve HCV infection prevalence among PWID in 30 years. This finding suggests that interventions aimed at increasing access to HCV treatment in community clinics will benefit individual PWID and reduce HCV infection prevalence.

Gambling-Related Intimate Partner Violence Against Women: A Grounded Theory Model of Individual and Relationship Determinants.

This study aimed to examine how problem gambling interacts with gendered drivers of intimate partner violence (IPV) against women to exacerbate this violence. Interviews were conducted with 48 female victims of IPV linked to a male partner's gambling; 24 female victims of IPV linked to their own gambling; and 39 service practitioners from 25 services. Given limited research into gambling-related IPV, but a stronger theoretical base relating to IPV against women, this study used an adaptive grounded theory approach. It engaged with existing theories on gendered drivers of violence against women, while also developing a grounded theory model of individual and relationship determinants based on emergent findings from the data. Gambling-related IPV against women was found to occur in the context of expressions of gender inequality, including men's attitudes and behaviors that support violence and rigid gender expectations, controlling behaviors, and relationships condoning disrespect of women. Within this context, the characteristics of problem gambling and the financial, emotional and relationship stressors gambling causes intensified the IPV. Alcohol and other drug use, and co-morbid mental health issues, also interacted with gambling to intensify the IPV. Major implications. Reducing gambling-related IPV against women requires integrated, multi-level interventions that reduce both problem gambling and gendered drivers of violence. Gambling operators can act to reduce problem gambling and train staff in responding to IPV. Financial institutions can assist people to limit their gambling expenditure and families to protect their assets. Service providers can be alert to the co-occurrence of gambling problems and IPV and screen, treat, and refer clients appropriately. Public education can raise awareness that problem gambling increases the risk of IPV. Reducing gender inequality is also critical.

Parent and child co-resident status among an Australian community-based sample of methamphetamine smokers.

INTRODUCTION: Children in families where there is substance misuse are at high risk of being removed from their parents' care. This study describes the characteristics of a community sample of parents who primarily smoke methamphetamine and their child or children's residential status. DESIGN AND METHODS: Baseline data from a prospective study of methamphetamine smokers ('VMAX'). Participants were recruited via convenience, respondent-driven and snowball sampling. Univariable and multivariable logistic regression analyses were used to estimate associations between parental status; fathers' or mothers' socio-demographic, psychosocial, mental health, alcohol, methamphetamine use dependence, alcohol use and child or children's co-residential status. RESULTS: Of the 744 participants, 394 (53%) reported being parents; 76% (88% of fathers, 57% of mothers) reported no co-resident children. Compared to parents without co-resident children, parents with co-resident children were more likely to have a higher income. Fathers with co-resident children were more likely to be partnered and not to have experienced violence in the previous 6 months. Mothers with co-resident children were less likely to have been homeless recently or to have accessed treatment for methamphetamine use. DISCUSSION AND CONCLUSIONS: The prevalence of non-co-resident children was much higher than previously reported in studies of parents who use methamphetamine; irrespective of whether in or out of treatment. There is a need for accessible support and services for parents who use methamphetamine; irrespective of their child or children's co-residency status. Research is needed to determine the longitudinal impact of methamphetamine use on parents' and children's wellbeing and to identify how parents with co-resident children (particularly mothers) can be supported.

A prospective cohort of people who use methamphetamine in Melbourne and non-metropolitan Victoria, Australia: Baseline characteristics and correlates of methamphetamine dependence.

INTRODUCTION AND AIMS: Limited research has investigated methamphetamine use and related harms in rural and regional Australia. We investigated whether people who used methamphetamine in non-metropolitan Victoria differed in their sociodemographics and were more likely to be methamphetamine-dependent than those recruited in Melbourne. DESIGN AND METHODS: We used baseline data from an ongoing prospective cohort study, 'VMAX'. Participants were recruited from Melbourne and three non-metropolitan Victorian regions. Sequential multivariable logistic regression of nested models assessed unadjusted and adjusted associations between residential locations and methamphetamine dependence. RESULTS: The sample mostly (77%) comprised people who used methamphetamine via non-injecting means (N = 744). Thirty-nine percent were female. Melbourne-based participants were less likely than non-metropolitan participants to identify as Aboriginal and Torres Strait Islander, be heterosexual, have children and be unemployed. More frequent methamphetamine use (adjusted odds ratio 1.22, 95% confidence interval 1.12-1.34) and using crystal methamphetamine versus 'speed' powder (adjusted odds ratio 2.38, 95% confidence interval 1.26-3.64) were independently (P < 0.05) associated with being classified as methamphetamine-dependent. A significantly higher percentage of participants in every non-metropolitan region were classified as methamphetamine-dependent vs. those in Melbourne, but this relationship was attenuated when adjusting for methamphetamine use frequency and primary form used. Despite 65% of participants being classified as methamphetamine-dependent, less than half had recently (past year) accessed any professional support for methamphetamine, with minimal variation by recruitment location. DISCUSSIONS AND CONCLUSIONS: VMAX participants in non-metropolitan Victoria were more likely to be methamphetamine-dependent than those living in Melbourne. Unmet need for professional support appears to exist among people using methamphetamine across the state, regardless of geographical location.

The impact of exposure to wagering advertisements and inducements on intended and actual betting expenditure: An ecological momentary assessment study.

BACKGROUND AND AIMS: Research suggests that a large proportion of regular sports and race bettors experience harm related to their gambling. In Australia, people who bet regularly are targeted by a proliferation of different forms of inducements and advertising - many of which are believed to encourage excessive betting and erroneous perceptions of risk. However, scant research has examined the impact of marketing messaging to this group, which is also limited to cross-sectional or qualitative designs. We aimed to determine whether exposure to wagering advertisements and inducements influenced intended betting expenditure, actual betting expenditure, and spending more than intended. METHODS: We report on an ecological momentary assessment study, measuring regular exposure to 20 different forms of marketing, as well as wagering spend from 318 race bettors and 279 sports bettors. Up to 15 assessments per participant were conducted over 3 weeks (mean = 11.46, median = 14), yielding 6,843 observations for analysis. RESULTS: Exposure to advertising and inducements was reliably linked to a greater likelihood of betting, higher intended and actual betting expenditure, and spending more than intended. "Push" messaging and inducements that convey the impression of reduced risk (stake-back inducements and multibet offers) were particularly influential, as well as brands promoted during events and advertisements on betting websites/apps. DISCUSSION AND CONCLUSIONS: Given that a large proportion of regular sports and race bettors experience problems, restrictions on these forms of marketing are advisable. These findings suggest that this is particularly important for marketing that is "pushed" to gamblers or that suggests reduced risk.

Correlates of alcohol consumption on heavy drinking occasions of young risky drinkers: event versus personal characteristics.

AIMS: Risky single-occasion drinking (RSOD) by young people is a serious public health issue, yet little is known about the specific circumstances of risky drinking occasions. This study examined the independent effects of event- and individual-specific variables on RSOD. DESIGN: Longitudinal cohort study measuring self-reported RSOD and event- and individual-specific variables across two drinking occasions approximately 1 year apart. SETTING: Metropolitan Melbourne, Australia. PARTICIPANTS: A sample of 710 young risky drinkers aged between 18 and 25 years and defined as engaging in risky drinking practices (males: consumed alcohol in excess of 10 Australian Standard Drinks (ASD: 10 g ethanol) in a single occasion in the previous year; females: consumed alcohol in excess of seven ASD for females in a single occasion in the previous year). MEASUREMENTS: Random digit-dial telephone landline survey of the most recent heavy drinking occasion and socio-demographic variables. The primary outcome was the log of the total drinks consumed in the most recent heavy drinking occasion. Event-specific (e.g. number of drinking locations) and time-varying (e.g. weekly income) and time-invariant (e.g. sex) individual-specific variables were examined as correlates of total drinks consumed. FINDINGS: Changes in event-specific characteristics including the length of the drinking occasion (Likelihood Ratio χ2 (2) = 24.4, P < 0.001), the number of drinking locations (Wald χ2(1)  = 7.6, P = 0.006) and the number of different drink types (Wald χ2(1)  = 13.6, P < 0.001) were associated with increases in total drinks consumed, after adjustment for time-invariant and time-variant individual-specific variables such as gender, income level and weekly consumption. Few other effects were noted. CONCLUSIONS: Event-specific characteristics are important predictors of the number of drinks consumed during risky single occasion drinking (RSOD) and illustrate the importance of event contexts when considering interventions targeting RSOD. The total number of drinks consumed in a RSOD session appears to rise independently with the duration of the drinking event, the number of drinking locations and the number of different types of beverage consumed.

Trends in morphine prescriptions, illicit morphine use and associated harms among regular injecting drug users in Australia.

This paper examines population trends in morphine prescriptions in Australia, and contrasts them with findings from annual surveys with regular injecting drug users (IDU). Data on morphine prescriptions from 1995 to 2003 were obtained from the Drug Monitoring System (DRUMS) run by the Australian Government Department of Health and Ageing. Data collected from regular IDU as part of the Australian Illicit Drug Reporting System (IDRS) were analysed (2001 - 2004). The rate of morphine prescription per person aged 15 - 54 years increased by 89% across Australia between 1995 and 2003 (from 46.3 to 85.9 mg per person). Almost half (46%) of IDU surveyed in 2004 reported illicit morphine use, with the highest rates in jurisdictions where heroin was less available. Recent morphine injectors were significantly more likely to be male, unemployed, out of treatment and homeless in comparison to IDU who had not injected morphine. They were also more likely to have injected other pharmaceutical drugs and to report injection related problems. Among those who had injected morphine recently, the most commonly reported injecting harms were morphine dependence (38%), difficulty finding veins into which to inject (36%) and scarring or bruising (27%). Morphine use and injection is a common practice among regular IDU in Australia. In some cases, morphine may be a substitute for illicit heroin; in others, it may be being used to treat heroin dependence where other pharmacotherapies, such as methadone and buprenorphine, are perceived as being unavailable or undesirable by IDU. Morphine injection appears to be associated with polydrug use, and with it, a range of problems related to drug injection. Further research is required to monitor and reduce morphine diversion and related harms by such polydrug injectors.

Prevalence and correlates of drink driving within patrons of Australian night-time entertainment precincts.

BACKGROUND: Drink driving is a significant public health concern, and contributes to many road fatalities worldwide. The current study is the first to examine the prevalence and correlates of drink driving behavior in a sample of night-time entertainment precinct attendees in Australia. METHODS: Interviews were conducted with 4214 night-time entertainment precinct attendees in two metropolitan and three regional cities in Australia. Seven correlates of self-reported drink driving were examined: gender, age, occupation, blood alcohol concentration (BAC), alcohol consumed prior to attending a licensed venue, energy drink consumption, and other drug consumption. RESULTS: Fourteen percent of night-time entertainment precinct attendees reported drink driving in the past three months. Bivariate logistic regression models indicated that males were significantly more likely than females to report drink driving in the past three months. Blue-collar workers and sales/clerical/administrative workers were significantly more likely to report drink driving behavior in the past three months than white-collar workers. The likelihood of reporting drink driving during the three months prior to interview significantly increased as BAC on the current night out increased, and when patrons reported engaging in pre-drinking or other drug use. The multivariate model presented a similar pattern of results, however BAC and pre-drinking on the night of the interview were no longer independent significant predictors. CONCLUSIONS: Males, blue collar/sales/clerical/administrative workers, and illicit drug consumers were more likely to report engaging in drink driving behavior than their counterparts. Interventions should focus on addressing the considerable proportion night-time entertainment precinct attendees who report engaging in drink driving behavior.

Diversion and injection of buprenorphine-naloxone film two years post-introduction in Australia.

INTRODUCTION AND AIMS: We report 2 years of post-marketing surveillance of the diversion and injection of buprenorphine-naloxone (BNX) film following its introduction in 2011. DESIGN AND METHODS: Interviews were conducted with people who inject drugs regularly (PWID) (2004-2013), opioid substitution therapy clients (2013, n = 492) and key experts (n = 44). Key outcomes were unsanctioned removal of supervised doses, diversion, injection and street price. Prevalence of past 6-month injection among PWID was adjusted for background availability of opioid substitution therapy medications using sales data. RESULTS: Among out-of-treatment PWID, the levels of regular (weekly+) BNX film injection were comparable to methadone and BNX tablets, and lower than mono-buprenorphine, adjusting for background availability. Fewer BNX film clients [3%; 95% (CI) 1-5] regularly injected their medication than mono-buprenorphine clients (25%; 95% CI 11-39), but at levels equivalent to those among methadone (3%; 95% CI 1-6) and BNX tablet clients (2%; 95% CI 0-6). Key experts perceived BNX film needed less supervised dosing time as it dissolved rapidly and was harder to remove from the mouth than sublingual tablets; however, removal of supervised doses was higher among BNX film clients (15%; 95% CI: 10-20) than methadone clients (3%; 95% CI 1-6), and not significantly different from BNX tablet (11%; 95% CI 2-21) and mono-buprenorphine clients (31%; 95% CI 16-46). DISCUSSION AND CONCLUSIONS: Two years post-introduction, levels of BNX film diversion and injection remained comparable with those for methadone and BNX tablets, and lower than mono-buprenorphine. We found no evidence that BNX film has lower non-adherence and diversion than the tablet formulation.
