Validação de um instrumento de avaliação da ingestão de bebidas alcoólicas e de etanol por consumidores excessivos

Abstract

The excessive consumption of alcohol and alcoholic drinks is an habit with high socioeconomic costs and a strong impact on health that requires research aiming at establishing adequate political options concerning trends, observed behaviours and consumption. Objectives: To validate an instrument to evaluate the consumption of the different kinds of alcoholic drinks and alcohol-related behaviours; to assess the determinants of alcoholic drinks consumption. Type of study: Validation study of an instrument to assess alcoholrelated behaviours. Place: Coimbra. Population: Excessive alcohol consumers. Methods: Cross-sectional study based on a questionnaire and biochemical markers assessment, aiming to validate an instrument to evaluate alcohol consumption and alcoholrelated behaviours. Results: A correlation between age at first contact with alcohol and the begining of the regular consumption(r = 0,72; p < 0,001) was found. Alcohol consumption in the last 12 months correlated with - % CDT (r = 0,54; p < 0,001) and with γ-GT (r = 0,47; p < 0,001). Conclusions: The validity of the instrument developed to evaluate alcohol-related behaviours is acceptable and therefore it may be used to establish hierarchy between levels of alcohol consumption defined by categories of ingestion and negative consequences.
