Association between Social Media Use for Health Purpose and Depressive Symptoms

Objectives: This study examines the relationship between social media use for health purposes and depressive symptoms across four age groups: young adults (18‐34), younger middle-aged adults (35‐49), older middle‐aged adults (50‐64), and older adults (65+). While research often focuses on younger or older populations, middle-aged adults receive less attention despite their distinct social media engagement. As social media’s role in health grows, this study explores its varying effects on depression across life stages. Methods: A sample of 6,789 adults aged 18 and older was drawn from the 2017 and 2018 Health Information National Trends Survey (HINTS). Multiple linear regression analyses stratified by age were conducted to predict depression levels based on social media use for health purposes. Results: Social media use for health was positively associated with depressive symptoms in three age groups, but not among those aged 65 and older. The relationship varied by age, with different demographic factors influencing the association. Conclusion: This study highlights the need for targeted interventions to improve digital health literacy, provide age-specific support, and address broader social factors impacting mental health. A comprehensive approach can help mitigate the potential risks of social media use on mental well-being.
