“…Moreover, we make use of an objective measure of intoxication (based on a breathalyzer reading), which further reduces measurement error problems within the data. Second, the response rate for this research was much lower than in prior similar intercept survey research in Hamilton (see Cameron et al, 2018a , Cameron et al, 2018b ), which may reduce somewhat the representativeness of the sample.…”

“…Hamilton CBD was chosen for convenience (proximity to the researcher’s institution), previous researcher experience with the location, and comparability with past research in the Hamilton night-time economy. Following an established research protocol for street-intercept surveys ( Cameron et al, 2018a , Cameron et al, 2018b ) and a systematic random sampling technique, every seventh pedestrian passing through a fixed location was invited to participate in the survey. The fixed location for the research was between the main taxi stand and the most popular bars in the CBD, in a well-lit and safe site.…”

Highlights A substantial minority of the ambient population in the night-time economy had engaged in side-loading. Unlike pre-drinking, side-loading was not statistically significantly associated with greater levels of intoxication (as measured by breath alcohol content). Side-loading might not be used as a method for drinkers to enhance intoxication, but instead as a means of sustaining a target level of intoxication.

“…We found no difference in intoxication levels between men and women, unlike Cameron et al . [32], who found that average breath alcohol concentration flattened out for women from midnight, but continued to increase throughout the night for men (the lack of gender differences in intoxication is also clear from a plot of average breath alcohol concentration over time, as shown in Figure S1). It is unclear why this change in the temporal pattern of intoxication has occurred, and this warrants further investigation.…”

“…The fieldwork team consisted of four interviewers and two supervisors. Following an established research protocol [31,32], every seventh pedestrian passing through a fixed location was offered the opportunity to participate in the survey. In practice, the four interviewers separated into two pairs, with one pair counting pedestrians and inviting participants moving in one direction, and the other pair doing the same for pedestrians moving in the opposite direction.…”

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.

“…A 2014 review reported that the majority of the research into this behaviour had been conducted in the US or the UK 9 . More recently, a number of other countries such as Switzerland, 10,11 Denmark, 12 Brazil, 13 New Zealand 14 and Australia 15-18 have also started to investigate this phenomenon. However, the generalisability of these studies to a larger population is not always possible due to limits in sample size, representativeness and cultural differences.…”

Objective: To cross-sectionally examine heavy episodic drinking (HED) and pre-loading with alcohol among young Australian women in relation to the alcohol-induced adverse outcomes of memory loss, vomiting and injury. Methods: A total of 7,800 participants, aged 20-25 years, from the 1989-95 cohort of the Australian Longitudinal Study on Women's Health answered all questions on alcohol use, reported drinking alcohol in the previous year and were not pregnant at the third survey in 2015. Log-binomial models were used to estimate prevalence ratios for adverse outcomes associated with increased frequency of HED and pre-loading. Results: The majority of participants reported HED (83.4%) and/or pre-loading (65.6%), which had a moderate correlation (r=0.646). Just over half (55.2%) of participants experienced at least one adverse event, with vomiting being most common. As the frequency of HED or preloading increased, so did the risk of an adverse outcome. Conclusions: Both HED and pre-loading pose a risk to young Australian women, and that risk rises with increased frequency. Implications for public health: Although HED has been a target of public health policy and interventions, pre-loading has received limited attention. In addition to addressing HED, there is a need to consider the risk posed by pre-loading, a related, yet unique risky drinking behaviour.
