Associations Between Characteristics of Adolescent and Young Adult Cancer Survivors and Their Use of Different Social Media Platforms: An Observational Study of Social Media Accounts.

Abstract

Background: The growing number of adolescent and young adult (AYA) cancer survivors and their unmet needs demand innovative communication and care strategies. This study uses social media data to examine how survivors' demographic and clinical characteristics relate to their social media use. Methods: Data from 300 AYA cancer survivors on six social media sites (YouTube, Instagram, Facebook, TikTok, Reddit, X/formerly Twitter) were collected between August 2022 and March 2023 and analyzed using descriptive statistics and statistical tests (chi-square, Fisher's exact, Welch, Games-Howell post-hoc, logistic regression). Results: Significant differences were observed across platforms for mean current age (p < 0.001) and age at diagnosis (p < 0.001). We also found significant associations between social media type used and current age, age at diagnosis, years since diagnosis, and the timing of social media account creation. AYAs who created their social media account post-diagnosis were less likely to use YouTube (p = 0.003) and more likely to use Facebook (p = 0.009). Treatment completion was associated with increased use of platform X (p = 0.004). Non-White individuals in our sample were less likely to use Facebook (p = 0.008). Significant associations were found between observed sex and platform usage (p < 0.001), with males more likely to use Reddit (p < 0.001) and X (p < 0.001). Conclusions: Significant associations were found between demographic and clinical attributes of AYA cancer survivors and the type of social media they used, suggesting that AYA-specific social media-based interventions should be tailored to subgroup characteristics (e.g., social media type, developmental stage based on age at diagnosis and current age, sex).
