Use of social media has been linked to increased anxiety and depression, as well as reduced well-being in adolescents and young adults, but similar associations in older adults have not been well studied, and longitudinal data are lacking, Ron H. Perlis, MD, of Massachusetts General Hospital, Boston, and colleagues wrote in their paper, which was published in JAMA Network Open.
To examine the association between social media use and depressive symptoms in older adults, the researchers reviewed data from 13 waves of an internet survey conducted each month between May 2020 and May 2021. The survey respondents included individuals aged 18 years and older, with a mean age of 56 years.
In the study the researchers analyzed responses from 5,395 individuals aged 18 years and older, with a mean age of 56 years. The study participants had minimal or no depressive symptoms at baseline, according to scores on the nine-item Patient Health Questionnaire (PHQ-9).
Overall, 8.9% of the respondents reported a worsening of 5 points or more on the PHQ-9 score on a follow-up survey, which was the primary outcome. Participants who reported using social media platforms Snapchat, Facebook, or TikTok were significantly more likely to report increased depressive symptoms, compared with those who did not report use of social media. The fully adjusted odds ratio was largest for Snapchat (aOR, 1.53), followed by Facebook (aOR, 1.42), and TikTok (aOR, 1.39).
Incorporating recent television and internet news terms, such as COVID-19, changed the association for Snapchat, for which the aOR decreased from 1.53 to 1.12 when news source terms were included in the survey. TikTok and Facebook associations remained similar.
When the results were further stratified by age, use of TikTok and Snapchat was associated with depressive symptoms in those aged 35 years and older, but not in those younger than 35 years. However, the opposite pattern emerged for Facebook; use was associated with depressive symptoms for individuals younger than 35 years, but not in those aged 35 years and older (aOR, 2.60 vs. aOR, 1.12).
The association between increased self-reported depressive symptoms and use of certain social media platforms was not impacted by baseline social support or face-to-face interactions, the researchers noted.
Family physician was surprised results weren’t more significant
In the current study, “I was honestly surprised the results weren’t more significant,” Mary Ann Dakkak, MD, of Boston University said in an interview. “That said, social media uses during the COVID pandemic may have been a necessary social outlet and form of connection for many people who were otherwise isolated.”
To still see a significant increase in depression when social media could have been a positive force may suggest a heavier impact during “normal” times, she added.
“It is not surprising that what we see in youth is shown among adults,” noted Dr. Dakkak, who was not involved with this study. “I always tell my patients that what is good for their children is good for the adults too, and vice versa.
“We expect to see outcomes of this on youth and adults who have been more isolated, who have used more screen time for learning, work, connection and boredom, in the near future,” she said. “The complex nature of why social media may have been used more heavily for connection during a time when in-person meetings were not possible may be a heavy confounder as the typical profile of heavy social media users may have differed during the COVID shutdowns.”
