A new analysis of 23 years of Australian Household, Income and Labour Dynamics in Australia (HILDA) survey data finds parental drinking habits have the strongest influence on children between ages 15 and 17.
Researchers tracked more than 6,600 people and 43,000 observations, linking individuals’ alcohol use at different ages to their parents’ average drinking when the child was 12–18.
Parental influence wanes through the twenties and resurfaces for many at 28–37, when adults become parents themselves.
The effect is largely same-sex: mothers most strongly influence daughters, fathers influence sons, with limited crossover.
Comparisons including non-birth caregivers suggest household norms, not genetics, drive much of the effect.
The study stresses that repeated patterns matter more than one-off occasions and notes long-term data showing parental supply of alcohol is associated with heavier teen drinking later.
It recommends harm-minimisation measures: moderate, low-key parental drinking, avoiding supplying alcohol to teenagers, and clear rules and communication.
Broader trends show a decline in teenage drinking in high-income countries—Australia’s reported drinking among 14–17-year-olds fell from about 70% in 2001 to ~30% by 2022–23.
