[Alcohol drinking patterns in Spain: a country in transition].

BACKGROUND Alcohol consumption in Mediterranean countries is in a transition period. The objective is to describe in the Spanish adult population the pattern of alcohol consumption by major sociodemographic variables. METHODS A cross-sectional study among 20,608 individuals aged ≥ 15 years who participated in the Spanish Health Interview Survey (ENS) 2011-2012. According to average intake, people were classified as heavy drinkers if they drank ≥ 40 g/day of alcohol (men) or ≥ 24 g/day (women). Binge drinking was defined as the consumption of ≥ 6 standard drinks (men) and ≥ 5 (women) at any drinking occasion (4-6 hours) in the last year. The beverage preference and the trend for 1987-2012 (ENS of these years) were estimated. The relationship of the distribution of drinking patterns with sociodemographic variables was analyzed using adjusted logistic regression models. RESULTS The prevalence of heavy drinkers was 1.3% (2% in men and 0.7% in women). In men, heavy drinking was more frequent among 45 to 64 year olds (odds ratio (OR)=2.92 compared to men of 15-29 years; CI 95%: 1.59-5.38) and those born in Spain (OR=3.45; CI 95%: 1.59-7.69). In women, the only differences observed were those regarding education level, with heavy drinking increasing as the level of education increases (p linear trend <0.001). The prevalence of binge drinking during the last year was 19.6% in men and 7.1% in women. In both genders, the risk of binge drinking decreased with age and increased with higher education level (p linear trend <0.001). The standardized prevalence of heavy drinkers has declined from 18.8% in 1987 to 1.3% in 2012. CONCLUSION Alcohol consumption in Spain is consistent with the model for countries in transition, where binge drinking is the most common pattern of excessive use of alcohol. A strong decline in heavy drinkers was observed and wine has been displaced by beer in beverage preference.
