Tracking the decline in Australian adolescent drinking into adulthood

Area of Science:

• Public Health
• Epidemiology
• Sociology

Background:

• Adolescent alcohol consumption in Australia has significantly decreased since the early 2000s.
• This study investigates if these declines persist into adulthood and across different demographic groups.

Purpose of the Study:

• To examine the maintenance of reduced adolescent drinking patterns into adulthood.
• To assess the consistency of these trends across sex and socio-economic status.

Main Methods:

• Utilized quasi-cohorts from seven waves of Australian household survey data (2001-2019).
• Analyzed data from 20,733 participants aged 14-24, grouped into birth cohorts.
• Measured past-year alcohol consumption, regular risky drinking, and total alcohol volume, with socio-economic status based on residence.

Main Results:

• Drinking declines were consistent across socio-economic groups and similar for males and females.
• More recent birth cohorts exhibited significantly lower drinking levels across all measures.
• Cohort differences in drinking diminished with increasing age, though lower levels were maintained up to age 24.

Conclusions:

• Adolescent cohorts with lighter drinking patterns maintain reduced consumption into early adulthood.
• Sustained reductions in alcohol and risky drinking are evident across socio-economic strata.
• These findings highlight a generational shift in drinking behaviors among young Australians.
