Influencer Alcohol Content Boosts Drinking Urges in Young Adults, Study Finds

Alcohol-friendly scenes in social media influencers' daily life videos significantly increase drinking urges among young viewers, according to a new experimental study.

Unlike previous research that only established correlations, this study is notable for being the first to use a randomized controlled trial to establish a temporal causal relationship between content exposure and drinking urges.

A joint research team from Rutgers University and Harvard University published the findings in JAMA Pediatrics on the 24th (local time).

The researchers partnered with online survey firm YouGov to recruit 2,000 U.S. adults aged 18-24, randomly assigning them to two groups. One group viewed 20 Instagram posts from influencers featuring drinking scenes or images of alcohol bottles and glasses, while the other group watched alcohol-free daily life videos from the same influencers.

Measuring changes in drinking urges after viewing, participants exposed to alcohol-friendly content were 73% more likely to experience increased drinking urges than those who were not. The figure remained unchanged even after adjusting for variables including daily social media usage time, lifetime drinking experience, and previous exposure to alcohol marketing.

Participants who reported trusting the influencer were more than five times more likely to experience increased drinking urges than those with lower trust levels. The analysis suggests content influence is amplified when combined with viewers' trust relationships. Participants who had consumed alcohol within the past 30 days were 40% more likely to experience increased urges after viewing alcohol-friendly videos, while those who had engaged in binge drinking during the same period were 30% more likely.

John-Patrick Allem, corresponding author and Rutgers University professor, said, "Any amount of alcohol increases the risk of certain cancers along the gastrointestinal tract, including the mouth, esophagus, and colon." He added, "This is the first study to use a randomized trial to demonstrate that social media alcohol exposure actually triggers drinking urges."

He continued, "We plan to further investigate the impact on young people by categorizing content sources into influencer posts, brand advertisements, and artificial intelligence (AI)-generated content."

Co-author Alex Russell, Harvard Medical School professor, emphasized, "The key to alcohol problem prevention is delaying the onset of drinking." He added, "As the digital environment's influence on adolescent drinking behavior grows, prevention strategies must also focus on the online space."
