Introduction: In Spain, alcohol consumption patterns are changing from a Mediterranean to a Northern Europe pattern, although, high-risk drinkers prevalence has decreased in the last few decades. Therefore, it is of interest to study the independent effects of age, period, and cohort on low-risk drinkers prevalence, high-risk drinkers prevalence, and on the total volume of alcohol consumed in the Spanish adult population.


Methods:
Data were taken from 9 surveys from the National Health Survey and from the European Health Survey of Spain from 1987 to 2014. The sample size was of 180,153 individuals aged 15 and older. According to the average grams of pure ethanol consumed, participants were classified into low-risk drinkers (1-39 g/day in men, and 1-23 g/day in women), and high-risk drinkers (≥40 g/day in men, and ≥24 g/day in women). Volume of alcohol consumption was also measured.


Results:
From 1987 to 2014, in both sexes, there was a decrease of alcohol consumption with age, an increase in low-risk drinkers prevalence across periods and cohorts, a drop in high-risk drinkers prevalence, as well as a decline in alcohol volume intake. High-risk drinkers prevalence peaked in cohorts born from the 1940s to the 1960s, whereas there was an increase in low-risk drinkers prevalence thereafter. A generational shift has been observed, due to the most recent cohorts born after the 1960s, who are low-risk drinking cohorts, with lower rates of alcohol consumption.


Conclusions:
In Spain, since the cohorts born in the 1960s, there has been an increase in the prevalence of low-risk drinkers, whereas high-risk drinkers prevalence has declined, leading to a global drop in the alcohol volume consumption. Further studies should focus on studying trends of more complex Mediterranean patterns.
