The relationship between birth order and acute alcohol intoxication among Dutch adolescents

Abstract

Background: Prior research demonstrated the relationship between birth order and adolescent risky behavior. The possible connection between the presence of siblings and birth order and underage alcohol abuse is unknown. Methods: Our study involves 10 years of data collection on underage alcohol intoxication in Dutch hospitals. A total of 2,234 patients were included in the current study. Results: Adolescents treated for alcohol intoxication less often have no siblings (6.7%) than the population has (14.8%). Furthermore, middle and youngest children are overrepresented in the patient population. Conclusion: The presence of older siblings is a risk factor for acute alcohol intoxication.
