Influence of Drinking Context and Age of Onset on Alcohol Consumption Patterns and Motivations Among Uruguayan Adults

Abstract

Objectives: An early age of drinking onset is linked to a greater likelihood of alcohol-related problems. Alcohol use occurs in places featuring characteristic social groups, and different drinking contexts are associated with different levels of alcohol-related outcomes. Drinking context may affect drinking motives, expectations or alcohol-related outcomes in concert with individual-level variables. The study aimed to examine how the preferred drinking context and age of the first drink affects the occurrence and volume of alcohol use, drinking motives and alcohol-related expectations. Methods: This cross-sectional study was conducted at Faculty of Veterinary Medicine, University of the Republic, Montevideo, Uruguay, from September 2020 to January 2021. Uruguayan citizens ≥18 years old were asked about their preferred drinking context, the age of first alcohol use and alcohol consumption frequency. In addition, the Drinking Motives Questionnaire and Alcohol Outcome Expectancies Questionnaire were used. Results: A total of 752 Uruguayan citizens were included. The distribution of alcohol consumption across social contexts was not influenced by the age of first alcohol use. Those who began drinking early and endorsed solitary drinking reported higher frequency of drinking (P P P P P Conclusion: Solitary drinking as a high-risk drinking context is likely to interact with the age of first alcohol use, suggesting that drinking in specific contexts is associated with specific drinking motivations and expectancies. This study represents progress towards exploring factors that influence alcohol consumption among a broader range of socio-cultural populations.
