Aims: To research whether the rising number of hospital treatments of alcohol intoxication is an indicator of an increase in risky alcohol consumption among adolescents. Methods: This was investigated within the framework of two secondary analyses (examination of crimes committed and accidents caused under the influence of alcohol among 10 – 20-year-old adolescents, as well as the alcohol blood concentration (BAC) of adolescents treated in hospital, n = 1 020) and a field study (population survey, n = 285). Results: The number of hospital treatments was positively correlated with crimes, but not with accidents under the influence of alcohol. In a city with a high prevalence of hospital treatments related to alcohol intoxication, more people would primarily call an ambulance as compared to a city with a low prevalence. The average BAC continuously declined within a two-year-period. Conclusions: The number of hospital treatments and criminal offenses committed under the influence of alcohol is indicative of an increase in risky alcohol consumption. However, the number of hospital treatments is associated with a higher sensitivity of the population and is not supported by the number of accidents under the influence of alcohol.
