A PLoS One prospective cohort study by a Chinese research team presents what it says is the first investigation of mobile phone use and rheumatoid arthritis incidence. Using UK Biobank data, the study reports higher risks among mobile phone users and those using a phone for more than 30 minutes per week, among 479,966 participants where 6,082 developed rheumatoid arthritis during a median follow-up time of almost 14 years.

"To our knowledge, the relationship between MPU and the incidence of RA remains unexplored."

— Ren et al.

"Individuals who used cell phones had a 14% elevated risk of the onset of RA (HR: 1.14, 95% CI: 1.07-1.23), with an 8% elevated risk (HR: 1.08, 95% CI: 1.02-1.15) observed among those who used a mobile phone for more than 30 minutes per week."

— Ren et al.

"Results indicate that increased MPU, longer duration of use, and greater weekly mobile phone usage time may be associated with an elevated risk of developing RA."

— Ren et al.
