| Summary: | Abstract Traumatic brain injury (TBI) is often the leading cause of death and the most common cause of permanent disability in children and young adults. The hospital admission rates as well as the incidence and mortality rates of TBI vary enormously in different countries and populations. Even though alcohol misuse is a well-known modifiable risk factor for TBI and other injuries, few studies have been carried out on drinking patterns in relation to TBI, alcohol’s role in recurrent brain injuries as well as TBI in relation to alcohol use in children and adolescents. The Northern Finland 1966 Birth Cohort was used to study the epidemiology and recurrence of TBI as well as alcohol use by children with TBI by the age of 14 years and those who sustained TBI later in life. The role of parents’ alcohol misuse on children’s TBI was also studied. The incidence of TBI in the whole study population was 118/100 000 person-years (PY), and the pediatric incidence of TBI (children aged under 16 years) was 130/100 000 PY. Up to the age of 10 years, the occurrence of TBI did not differ by gender, but after that age, boys and men had a higher incidence compared to girls and women. Mortality from TBI in the whole study population was 14/100 000 PY. Parental alcohol misuse and male gender were significant risk factors for the occurrence of TBI in childhood. Drinking to intoxication at the age of 14 years was a more common habit of TBI subjects than controls, especially among girls. Frequent alcohol drinking and drunkenness reported at the age of 14 years as well as male gender were independent predictors of TBI later in life. An alcohol-related first TBI and urban place of birth were found to be significant risk factors for recurrent TBI. A significant positive correlation between first and recurrent TBIs with respect to alcohol involvement was observed. Alcohol drinking and parental alcohol misuse should be recognized among children and adolescents with acute TBI. Because alcohol drinking predicts the recurrence of TBI, a brief ...
