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.

A comparative study of blood alcohol concentrations in Australian night-time entertainment districts

INTRODUCTION AND AIMS There is little research describing how intoxication levels change throughout the night in entertainment districts. This research aims to describe levels of alcohol intoxication across multiple Australian metropolitan and regional nightlife districts. DESIGN AND METHODS This study was conducted in the night-time entertainment districts of three metropolitan cities (Sydney, Melbourne and Perth) and two regional cities (Wollongong and Geelong) in Australia. Data collection occurred approximately fortnightly in each city on a Friday or Saturday night between 8 pm and 5 am. Brief structured interviews (3-10 min) and breathalyser tests were undertaken in busy thoroughfares over six months. RESULTS Of the 7037 individuals approached to participate in the study, 6998 [61.8% male, mean age 24.89 years (standard deviation 6.37; range 18-73)] agreed to be interviewed. There was a linear increase in blood alcohol concentration (BAC) levels throughout the night. Post hoc testing revealed significantly more highly intoxicated participants (i.e. BAC above 0.10 mg of alcohol per 100 mL of blood) after midnight (P < 0.05). The overall mean BAC was 0.06 mg/100 mL. Men were more intoxicated than women earlier in the night, but gender differences disappeared by 3 am. There was no age differences in intoxication earlier in the night, but after midnight, patrons over the age of 21 showed increasing BAC levels. DISCUSSION AND CONCLUSIONS There is a consistent trend across the cities of high to very high levels of intoxication later in the night, with trends after midnight being significantly different to those before.

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.

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.

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.
