Association between Social Media Use and Depressive Symptoms: A Cross-sectional Survey (Preprint)
BACKGROUND The use of social media or social networking site (SNS) is increasing across all age groups, and one of the primary motives of using SNS is to seek health-related information. Previous research shows inconclusive results regarding the effect of SNS use on depression, as social comparison that individuals experience while using SNS increases the likelihood of depression. But other argues the beneficial use of SNS in managing mental health. OBJECTIVE Our study aims to explore the relationship between SNS use for health purpose and depression across the four age groups (18-34 years old, 35-49 years old, 50-64 years old, and above 65 years old). METHODS A sample of 6,789 adults aged 18 and older was extracted from a 2017 and 2018 Health Information National Trends Survey (HINTS). Univariate and bivariate analyses to examine the association between each variable and four age groups were conducted. Multiple linear regression analyses to predict depression level among participants with use of SNS for health purpose were conducted. RESULTS SNS use for health purpose and depression were positively associated for all age groups with strongest association among the youngest group (=.113, P<.001). Income and self-reported health status indicated an inverse relationship for all age groups, while race and marital status differed by age group. Gender and frequency of visiting health care providers predicted higher level of depression depending on age group, such as positive association among 35-49 years old group (=.076, P<.05; =.077, P<.05, respectively). CONCLUSIONS Overall, SNS users may be susceptible to social comparison. Age-tailored interventions educating on healthy SNS use along with identifying individuals with existing depressive symptoms through assessment of SNS use pattern are needed.
