The Prevalence of Smartphones and WeChat Use Among Older Adults With Chronic Disease in a Western China.

Telemedicine is a promising way to deliver patient education and health services, but access to information technology among potential patients is a prerequisite. This study surveyed the prevalence of smartphone use and the use of the Chinese social networking platform WeChat and Wi-Fi access in the homes of older adults in a western area of China. A convenience sample of 225 older adults with chronic diseases in two tertiary hospitals was interviewed regarding smartphone ownership, WeChat use, and access to Wi-Fi at home. Participant ability in performing the activities of daily living was also assessed. Logistic regressions were used to analyze the independently associated factors of smartphone ownership, WeChat use, and Wi-Fi access at home. The results show that the prevalence of smartphone use was 19.6%, only 8.9% of those surveyed used WeChat, but 39.6% had access to Wi-Fi at home. Education level was the only factor significantly associated with the three dependent variables. Ability in performing activities of daily living was positively correlated with access to Wi-Fi at home (odds ratio, 2.549; P = .011). It will be difficult to implement telemedicine through smartphones in such relatively poor areas of China. Better-educated older adults who are less dependent in performing activities of daily living are potential users of telemedicine.
