Parental Drinking Linked to Impaired Parenting, Study Finds

No safe limit for parental alcohol use was identified.

A new systematic review from the University of Agder and Oxford Brookes University has found a clear association between alcohol use and impaired parenting practices. The research analyzed 68 studies published between 1991 and 2026, examining how drinking around children influences parenting behaviors and interactions.

Key Findings

• Higher alcohol intake increases the risks of stricter discipline and more conflict with children.
• Drinking is associated with reduced attentiveness and lower relationship quality between parent and child.
• No safe threshold for parental alcohol use was identified.

Researcher's Statement

“One of the key takeaways is not that every single glass of wine or beer is dangerous, but that there is no safe limit. Alcohol use affects parents, parenting practices, and children in different ways. We need to rethink what is safe.”
— Barbara Carvalho, doctoral research fellow at the University of Agder

Broader Context

Most studies (53 of 68) originated from the United States, which limits cross-cultural transferability. However, researchers emphasized that parents without alcohol use disorders (AUDs) may still negatively affect their children through their drinking patterns.

Carvalho noted the findings are particularly relevant in Norway, where drinking frequency is low but per-occasion consumption is high.

The study did not recommend abstinence but aimed to raise awareness of the possible consequences of drinking on parenting.
