Rural-Urban Disparities in Mobile Health Application Ownership and Utilization Among Cancer Survivors.

Objective: Mobile health applications (mHealth apps) can provide health care and health-promoting information while contributing to improving cancer survivors' quality of life and health outcomes. However, little is known about the rural-urban distribution of mHealth app ownership and utilization. In this study, we explore the characteristics of cancer survivors who own and use mHealth apps and examine rural-urban disparities in mHealth app ownership and utilization among cancer survivors.

Methods: We utilized data from the "Health Information National Trends Survey-Surveillance, Epidemiology, and End Results" pilot study, fielded among cancer survivors from 3 U.S. cancer registries (Iowa, New Mexico, and California) in 2021. Our sample included 942 cancer survivors who reported owning a smart device (a smartphone and/or a tablet computer). The analyses included computing weighted proportions and fitting a multivariable regression model.

Results: Overall, 60.3% of cancer survivors reported using mHealth apps, and 16.9% resided in rural areas. Approximately 45.0% of rural cancer survivors reported utilizing mHealth apps (vs 63.5% of urban survivors). Regression analysis revealed that rural cancer survivors had 46.0% lower odds of owning and using mHealth apps compared with their urban counterparts (adjusted odds ratio = 0.54; 95% CI: 0.36, 0.80).

Conclusions: Rural cancer survivors were less likely to own and use mHealth apps compared with urban survivors. Rural cancer survivors usually face structural and health care system-related barriers to health care access and affordability. Leveraging mHealth technology as a tool could potentially contribute to improving health care delivery for rural cancer survivors, and help address existing structural and informational barriers to access.
