Method: Secondary analyses of data from the 1986 Northern Finland Birth Cohort study were conducted. Participants were 6,963 individuals born in Finland. Multi-informant (parent, teacher, youth), multi-method (surveys, population registers) data were collected at birth, in childhood (age 8), in adolescence (age 16), and in young adulthood (up to age 28). In terms of the primary variables, parental alcohol use was measured at birth and in adolescence via parent report. Adolescent alcohol use was measured via self-report, whereas indicators of young adult alcohol abuse were assessed using hospital and criminal records. Structural equation modeling analyses were conducted in Mplus.
Results: Father’s alcohol use had distal (birth: b=.050, B=.12, p<.05) and proximal (adolescence: b=.020, B=.09, p<.05) associations with adolescent alcohol use, whereas mother’s alcohol use was only proximally related (b=.014, B=.06, p<.05) to teen drinking. Parent alcohol use in adolescence was related to young adult alcohol abuse indirectly through adolescent alcohol use, which was a strong proximal predictor of alcohol abuse (b=.586, B=.50, p<.05). Both family contextual risk at birth (b=.065, B=.08, p<.05) and childhood externalizing (b=.513, B=.15, p<.05) predicted alcohol abuse over and above alcohol use. Peer deviance was strongly related to alcohol use (b=.565, B=.74, p<.05).
Conclusions: Findings suggest that early and ongoing screening for parental alcohol use, especially that of fathers, could help identify youth at risk for adolescent alcohol use and progression to alcohol abuse. Likewise, early and sustained multi-component, ecological interventions are needed to reduce youth’s risk for alcohol use and abuse.
