Demographic and substance use factors associated with non-violent alcohol-related injuries among patrons of Australian night-time entertainment districts

This study examined the relationship between patron demographics, substance use, and experience of recent alcohol-related accidents and injuries that were not due to interpersonal violence in night-time entertainment districts. Cross-sectional interviews (n = 4016) were conducted around licensed venues in entertainment districts of five Australian cities. Demographic factors associated with non-violent alcohol-related injuries were examined, including gender, age, and occupation. The association between substance use on the night of interview; blood alcohol concentration (BAC), pre-drinking, energy drink consumption, and illicit drug use; and experience of injury was also explored. Thirteen percent of participants reported an alcohol-related injury within the past three months. Respondents aged younger than 25 years were significantly more likely to report an alcohol-related injury. Further, a significant occupation effect was found indicating the rate of alcohol-related injury was lower in managers/professionals compared to non-office workers. The likelihood of prior alcohol-related injury significantly increased with BAC, and self-reported pre-drinking, energy drink, or illicit drug consumption on the night of interview. These findings provide an indication of the demographic and substance use-related associations with alcohol-related injuries and, therefore, potential avenues of population-level policy intervention. Policy responses to alcohol-related harm must also account for an assessment and costing of non-violent injuries.

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.

Awareness and correlates of short‐term and long‐term consequences of alcohol use among Australian drinkers

Objective: To investigate awareness of short‐term and long‐term consequences of alcohol use among a sample of Australian adult drinkers. Demographic correlates of the awareness of each consequence were also explored.

Funder interference in addiction research: An international survey of authors

OBJECTIVE Scientific research is essential to the development of effective addiction treatment and drug policy. Actions that compromise the integrity of addiction science need to be understood. The aim of this study is to investigate funder (e.g. industry, government or charity) interference in addiction science internationally. METHOD Corresponding authors of all 941 papers published in an international specialist journal July 2004 to June 2009 were invited to complete a web questionnaire. A sensitivity analysis with extreme assumptions about non-respondents was undertaken. RESULTS The questionnaire was completed by 322 authors (response fraction 34%), 36% (n=117) of whom had encountered at least one episode (median=3, Interquartile range=4) of funder interference in their research: 56% in Australasia, 33% in Europe, and 30% in North America. Censorship of research outputs was the most common form of interference. The wording or writing of reports and articles, as well as where, when and how findings were released were the areas in which influence was most often reported. CONCLUSIONS Funder interference in addiction science appears to be common internationally. Strategies to increase transparency in the addiction science literature, including mandatory author declarations concerning the role of the funder, are necessary.

Correlates of verbal and physical aggression among patrons of licensed venues in Australia

INTRODUCTION AND AIMS The current study aimed to examine the association between patron demographics and substance use, and experiences of verbal and physical aggressive incidents within the last 3 months among patrons of night-time entertainment precincts (NEP) in Australia. DESIGN AND METHODS Patron interviews (n = 4216) were conducted around licensed venues in the NEPs of five Australian cities. Seven correlates of verbal and physical aggressive incidents were examined: gender, age, occupation, blood alcohol concentration, pre-drinking, energy drink use and illicit drug use in the current session. RESULTS A total of 7.5% and 8.2% of respondents reported involvement in a verbally and physically aggressive incident in the past 3 months, respectively. Multivariate logistic regression models indicated men and people <25 years old were significantly more likely to report both verbal and physical aggressive incidents. A significant occupation effect showed lower levels of both verbal and physical aggression in managers/professionals compared with non-office workers. The likelihood of being involved in a verbally aggressive incident significantly increased with energy drink consumption, while the likelihood of being involved in a physically aggressive incident significantly increased with blood alcohol concentration, energy drink consumption and illicit drug use. DISCUSSION AND CONCLUSIONS This study highlights the different correlates of verbal and physical aggression within NEPs, suggesting they should be viewed as distinct types of violence, rather than points on a continuum. Major modifiable correlates with verbal and physical aggression included intoxication, energy drink consumption, and illicit drug use, suggesting the need for further interventions and policy development to address these key issues.

Trends across the night in patronage, intoxication, and licensed venue characteristics in five Australian cities

ABSTRACT Background: While alcohol-related harm is reportedly greater on weekend evenings, research investigating trends in the intoxication levels of patrons and factors that increase risk of harm over the night is lacking. Objectives: The aim was to observe trends over the course of the night for patron demographics, venue characteristics and patron intoxication. Methods: Observations of licensed venues and patrons in night-time entertainment districts of five Australian cities were conducted. In total, 798 observations occurred between 9 pm and 2 am on Friday and Saturday nights across 61 unique bars, nightclubs, and pubs. Patron characteristics such as gender and percentage of patrons under 25 years of age were estimated. Measures of venue characteristics included number of patrons, percentage venue capacity, ease of patron movement, bar crowding, and time to service. Measures of intoxication included the percentage of patrons showing any signs of alcohol intoxication, percentage of patrons too intoxicated to remain in the venue, overall level of intoxication, and percentage of patrons showing signs of drug use. Results: Patron capacity increased across the night, peaking at 11 pm in bars, and 1 am in nightclubs. Patron intoxication measures increased for all venue types across the night. Patrons showed more signs of drug use in nightclubs than other venue types. Conclusions: Increasing intoxication and decreasing patron numbers later in the night provides support for restricted trading hours and improved responsible service of alcohol policies. Specific venue types should be targeted to reduce drug use in the night-time economy.

Targeting at-risk samples through brief face-to-face interviews in night-time entertainment precincts

ABSTRACT Aims: This exploratory paper investigates the demographic profile of patrons who may be underrepresented in face-to-face interviews by employing a brief version of an interview. Method: Patron interviews (n = 8,664) were conducted in seven Australian cities; 63% completed the full interview and 37% completed the brief interview. Assessed correlates of interview type comprised gender, age, pre-drinking, consumption of alcohol mixed with energy drinks, illicit drug use, involvement in verbal or physical aggression, alcohol-related injuries, and blood alcohol concentration (BAC). Results: Using a brief interview increased the response rate by 34%. Multi-level logistic regression models indicated compared to those who completed the full interview, brief interview respondents were more likely to be: male, have a BAC of ≥0.05 to <0.10 or ≥0.10 g/100 ml, report pre-drinking, and report involvement in physical aggression. Respondents were also less likely to compete the brief interview with each 1 year increase in age. Conclusion: Compared to longer interviews, brief patron interviews can capture a different and more at-risk demographic group and increase the overall response rate. These findings raise questions about the representativeness of long interview samples describing young drinkers who experience aggression. The study also provides the groundwork for future validation of brief interviews.

A mapping review of evaluations of alcohol policy restrictions targeting alcohol-related harm in night-time entertainment precincts

BACKGROUND Alcohol-related harm in night-time entertainment precincts (NEPs) is disproportionately high for the amount of alcohol consumed within these areas. Previous evaluations of alcohol restrictions targeting NEPs have often looked at restrictions in isolation and not attempted to create a comprehensive theoretical explanation that takes multiple restrictions into account. The aim of this review is to establish which restrictions have been adequately evaluated in previous literature, and to identify any research which may provide the basis for a theoretical model that explains the interactions between different alcohol restrictions in NEPs and their combined impact on alcohol-related-harm. METHODS A mapping review was conducted to plot evaluations of the effectiveness of different alcohol restrictions in NEPs at reducing assault and injury rates (protocol PROSPERO 2017: CRD42017069773). Six databases and 145 websites were searched, results were categorised based on the type of restrictions evaluated: Outlet density, trading hours, lockouts, price, patron bans, and drinks restrictions. RESULTS Forty-eight articles were identified out of 20,743 returned by the systematic search. Thirty-five of these papers were original works, and 13 reviews. Outlet density was examined in 15 of the papers, trading hours in 30, lockouts in 21, price in 2, patron bans in 7 and drinks restrictions in 15. CONCLUSION No pre-existing theoretical models were identified. Outlet density, trading hours, and price restrictions all had evidence that suggested high levels of effectiveness in NEPs and would be suitable for inclusion in a theoretical model. More research is required before attempting to include lockouts, patron bans and drinks restrictions in a theoretical model. Future research should focus on establishing a theoretical model based on evidence of effective alcohol restrictions and gathering an evidence base for under-researched restrictions.

Adolescent violence towards parents: prevalence and characteristics using Australian Police Data

Adolescent violence toward parents is a unique form of family violence which for many, including police personnel, challenges traditional views of parent–child relationship, and raises questions about victimization. There has been minimal research in Australia to date in this area, and knowledge about both prevalence rates and the characteristics of offenders and victims remains limited. This exploratory study utilized police data from four Australian States to document prevalence rates of reported offenses to police, and the characteristics of adolescent violence toward parents in Australia. Between 1% and 7% of family violence reported to the police is adolescent violence toward parents. The “typical” perpetrator is a 15- to 17-year-old Caucasian young man who is generally violent toward his mother. Findings are limited by the differing police practice and policy variations between States, including the use of police discretion, leaving several questions open for further investigation. In conclusion, there is a need for change in policy and practice with regards how best to assess and respond to adolescent violence toward parents.
