BACKGROUND
Background: Healthcare apps on smartphones are used to retrieve health information and manage health. A number of healthcare apps have been employed to support diabetes self-management, and evidence has accumulated on the outcomes of interventions using individual apps. However, only a small percentage of all healthcare apps have a proven effect on people with diabetes, and it is unclear which apps should be recommended in non-English-speaking countries. Verifying that the healthcare apps used by people with diabetes are useful for diabetes management behaviors will help healthcare providers know which apps to recommend.
OBJECTIVE
Objective: The purpose of this study was to clarify whether and how the use of healthcare apps affects the self-management behavior of people with diabetes.
METHODS
Methods: A cross-sectional questionnaire was given to patients with type 2 diabetes who were pre-registered with an Internet research company. The items on the questionnaire involved the use of smartphone healthcare apps, diabetes self-management behaviors (Japan Summary of Diabetes Self-Care Activities [J-SDSCA]), motivations for diabetes self-management (autonomous motivation and controlled motivation), and feelings of competence in self-management (Perceived Competence for Diabetes Scale). To examine whether a healthcare app had an effect on the self-management behavior score, a multiple regression analysis was conducted with the J-SDSCA score as the objective variable.
RESULTS
Results: Of the 253 participants, 61 (24.1%) indicated that they were currently using a healthcare app. Those using a healthcare app had a significantly higher J-SDSCA score than those not using one (beta =.15, 95% CI 0.60–3.54, P <.001). Regarding the frequency of exercise, the use of apps for steps and walking distance led to a significant difference (beta =.22, 95% CI 0.59–1.90, P <.001). For general diet, the use of any healthcare app had no significant effect (P =.22).
CONCLUSIONS
Conclusions: The use of healthcare apps was beneficial for diabetes self-management. Given that even non-specialized apps can improve diabetes self-management behaviors, health care providers should encourage patients to use apps that are tailored to their preferences and that are easy to use long-term. The use of healthcare apps was particularly associated with increased exercise regimen efforts. Recommending the use of healthcare apps, especially apps that include pedometers, could be useful when patients have problems with exercise.
