Landberg J, et al. - In offspring during youth and young adulthood, researchers explored the connection between various indicators of father's alcohol use (average volume of consumption, frequency of drinking into intoxication, having been apprehended for drunkenness and alcohol-related disorders) and suicidal behaviour (defined as suicide attempts and completed suicides). The research is based on a cohort of 68,910 Swedish citizens born between 1970 and 1985 and have fathers who partook in conscription for compulsory military training in 1969/70. During conscription, information on fathers’ alcohol use was obtained. Findings suggested an association of fathers’ alcohol use with increased risk of suicidal behaviour among offspring in youth and young adulthood. The highest risk, including being apprehended for drunkenness and diagnosed alcohol-related disorders, is observed for offspring to fathers with the most problematic consumption. The results, however, show that the offspring of fathers drinking below these levels often face an increased risk of suicidal behaviour. Furthermore, while the connections to a large extent are explained by other risk factors that tend to co-occur with parental heavy drinking, most indicators of fathers’ alcohol use are independently linked to increased risk of suicidal behaviour in offspring.
