Study Reveals Parents’ Drinking Habits Affect Teen Substance Use
A new study indicates that parents’ drinking habits significantly influence whether their children use alcohol or drugs. Researchers from the Federal University of São Paulo discovered that even if parents don’t stop drinking, specific parenting strategies can help break the cycle of substance use.
The study reviewed data from over 4,200 Brazilian teenagers and their parents. It found that a parent’s alcohol consumption increases the likelihood of their child drinking by 24%. This risk becomes even higher when parents use both alcohol and tobacco or vapes, with the chance rising to 28%. These findings were shared in the journal Addictive Behaviors.
The data was collected from 2023 to 2024 across four towns in Brazil, involving adolescents with an average age of 14.7 years and an equal number of boys and girls. According to Zila Sanchez, the study’s lead author, parents’ behavior plays a crucial role in shaping their children’s habits.
The research highlights that the best way to prevent teen substance use is for parents to model good behavior. When parents choose not to drink, a whopping 89% of adolescents also refrain from using alcohol or other drugs.
The home environment notably impacts whether teens use substances, and the study identified four parenting styles:
- Authoritative: Balances affection with clear rules (most effective).
- Authoritarian: Enforces strict rules without much warmth (less effective against alcohol).
- Permissive: Shows affection but lacks rules (provides no protection).
- Neglectful: Lacks both affection and rules (provides no protection).
Sanchez emphasizes that setting boundaries and showing affection can greatly reduce the risk posed by parental substance use. However, affection alone won’t prevent issues if drinking is viewed as a normal way to cope with stress.
The findings also come with caveats. The study, which captures a single moment in time, shows only correlations, not causation. It relies on teenagers’ self-reports, which can be unreliable, and the limited geographic focus may not represent global drinking cultures.
Understanding these dynamics is essential for parents, as teaching healthy habits can go a long way in keeping their children safe from substance use.
