Pre‐drinking behaviour of people in the night‐time economy: Evidence from a street‐intercept survey in New Zealand

Abstract

Introduction. Pre-drinking behaviour has grown in prevalence and generates harm for pre-drinkers and others. In this article, we answer three research questions: (i) Where and when do pre-drinkers obtain their alcohol?; (ii) What is the difference in the level of intoxication of pre-drinkers versus non-pre-drinkers, and how does this difference vary over the course of a night?; and (iii) Is the level of intoxication of pre-drinkers related to where and when they obtain their alcohol? Methods. We obtained data from 469 respondents using a street-intercept survey conducted in Hamilton, New Zealand in 2019. Data were analysed by cross-tabulation, linear regression and plotting the average intoxication level in the night-time economy over time. Results. The majority of pre-drinkers purchase their alcohol for pre-drinking on the day of consumption. Half of the same-day purchasers purchase before 6 pm. The average level of intoxication increases over the course of the night, and is unambiguously higher for pre-drinkers than non-pre-drinkers. The level of intoxication does not differ based on the source or timing of pre-drinking purchases. The main motivation for pre-drinking was price, especially among women. Discussion and Conclusions. Pre-drinking is a contributor to intoxication in the night-time economy, but most drinkers purchase their alcohol for pre-drinking before 7 pm. Further research is required to understand whether trading hours restrictions for offpremises alcohol suppliers will affect the most harmful drinking patterns. Price interventions to reduce the price differential between on-licenced and off-licence alcohol outlets offer the greatest potential to reduce pre-drinking and associated harm.

Alcohol consumption and heavy episodic drinking within different types of drinking occasion in Great Britain: An event-level latent class analysis

“…Mixed-trade drinking occasions also appear important for understanding harmful alcohol consumption as at least 65% of occasions involved heavy drinking in all three mixed-trade occasion types. Event-level studies identify occasions involving drinking across the on-and off-trade trade sectors as commonplace, associated with higher consumption levels and therefore higher risk [4,15,28,29]. However, beyond the specific practice of pre-drinking among young adults [30][31][32], little is known about the varying forms such occasions may take, who engages in them and how they contribute to some drinkers reaching high levels of alcohol consumption in a single day or across a week.…”

The impact of COVID-19 restrictions on acute hospital presentations due to alcohol-related harm in Waitematā Auckland, New Zealand

“…20 This must then reflect the availability and prominence of packaged alcohol consumption in New Zealand, which has been shown as problematic. 21 Published national data of drinking practices during the pandemic vary considerably. In Colombia, Mexico 22 and South Australia, 23 alcohol use reportedly decreased, while in Greece consumption was largely unchanged.…”
