A recent review published by The BMJ highlights the association between social media use and risky health behaviors among adolescents.
The study indicates that engaging with social media is linked to increased instances of alcohol, drug, and tobacco use, as well as anti-social behavior, risky sexual behaviors, and gambling among young people.
Notably, exposure to content promoting risky health behaviors on social media, such as alcohol advertising, demonstrated the strongest evidence of harm, particularly concerning alcohol consumption and unhealthy eating habits.
While social media is recognized as a platform for health promotion, concerns persist regarding its potential adverse effects on the health behaviors of adolescents.
Previous reviews focused on university and college students, lacked a specific examination of social media, and did not assess study quality.
To address these gaps, the researchers analyzed over 250 social media measures reported in 73 studies spanning from 1997 to 2022, involving 1.4 million adolescents with an average age of 15 years.
Although the majority of studies were conducted in high-income countries and varied in quality, the researchers utilized the GRADE system to assess the certainty of evidence.
Key findings revealed that frequent or daily social media use was associated with higher odds of alcohol consumption (48%), drug use (28%), and tobacco use (85%) compared to infrequent or non-daily use.
Exposure to content promoting risky health behaviors on social media, especially regarding unhealthy eating and alcohol use, exhibited the most substantial evidence of harm.
The study also found stronger associations for alcohol consumption among adolescents aged 16 years and older and for exposure to user-generated content compared to marketer-generated content.
Additionally, spending at least 2 hours a day on social media doubled the odds of alcohol consumption compared to less than 2 hours of use.
While the researchers acknowledge limitations, such as reliance on personal recall for social media measures, they emphasize the need for further research to establish causality, understand effects on health inequalities, and identify the most harmful aspects of social media.
As the digital landscape evolves, the study advocates for precautionary measures in academic, governmental, health, and educational sectors to address the potential risks associated with adolescents’ use of social media, particularly considering the inherent experimental and risk-taking behaviors of adolescence.
