Bottom Line: A higher percentage of males were involved in alcohol-related aggression compared with females.In males, the DE and DI patterns significantly increased the likelihood of alcohol-related aggression, whereas the DNE pattern was negatively associated.Similar results were found in females, although the DI pattern was not significantly associated with alcohol-related aggression.

ABSTRACT

Background: Although there have been a wide range of epidemiological studies examining the impact of patterns of alcohol consumption among adolescents, there remains considerable variability in both defining these patterns and the ability to comprehensively evaluate their relationship to behavioural patterns. This study explores a new procedure for defining and evaluating drinking patterns and integrating well-established indicators. The composite measure is then used to estimate the impact of these patterns on alcohol-related aggressive behaviour among Italian adolescents.

Methods: Data were collected as part of the 2011 European School Survey Project on Alcohol and other Drugs (ESPAD). A national sample of 14,199 students aged 15-19 years was collected using an anonymous, self-administered questionnaire completed in a classroom setting. Drinking patterns were established using principal component analysis. Alcohol-related aggression was analysed as to its relationship to patterns of drinking, behaviour of friends towards alcohol use, substance use/abuse, school performance, family relationships and leisure activities.

Results: Several specific drinking patterns were identified: "Drinking to Excess" (DE), "Drinking with Intoxication" (DI) and "Drinking but Not to Excess" (DNE). A higher percentage of males were involved in alcohol-related aggression compared with females. In males, the DE and DI patterns significantly increased the likelihood of alcohol-related aggression, whereas the DNE pattern was negatively associated. Similar results were found in females, although the DI pattern was not significantly associated with alcohol-related aggression. Overall, cigarette smoking, illegal drug use, truancy, limited parental monitoring, frequent evenings spent outside of the home and peer influence associated strongly with alcohol-related aggression.

Conclusions: Our findings suggest that drinking patterns, as uniquely monitored with an integrated metric, can: 1) explain drinking habits better than commonly used indicators of alcohol use and 2) provide a better understanding of behavioural risks such as alcohol-related aggression. Environmental background also appears to strongly associate with this type of aggressive behaviour.

Three-dimensional representation of the drinking patterns. “Drinking to excess” (upper panel), “Drinking with intoxication” (central panel) and “Drinking but not to excess” (lower panel) obtained through principal component analysis. Each point represents the value of the pattern corresponding to the combination of the three indicators (perceived intoxication, binge drinking, and alcohol use). Shade of grey varies from light to dark grey (from lowest to highest value).

Figure 1: Three-dimensional representation of the drinking patterns. “Drinking to excess” (upper panel), “Drinking with intoxication” (central panel) and “Drinking but not to excess” (lower panel) obtained through principal component analysis. Each point represents the value of the pattern corresponding to the combination of the three indicators (perceived intoxication, binge drinking, and alcohol use). Shade of grey varies from light to dark grey (from lowest to highest value).

Mentions: Figure 1 shows a three-dimensional representation of the aforementioned drinking patterns: points represent all the theoretical values that the specific pattern could assume in correspondence of the combination of frequencies of the three selected indicators. The points are presented in shades of grey, from light grey at the lowest value to dark grey at the highest. As shown, ED pattern had higher values at increasing frequencies of all indicators, DI pattern had higher values at increasing frequency of both alcohol use and intoxication, DNE pattern had higher values in correspondence with higher frequency of alcohol use and lower frequency of binge drinking.
