The Effectiveness Of Mobile Health Chronic Disease Management System Based Wearable Device On Elderly With Hypertensive And Diabetic In Community

Objective: The aim of this study is a six-month randomized controlled trial was conducted on elderly patients with hypertensive and diabetic in the community by mobile health chronic disease management system based on wearable devices.The relationship between frequency of mobile health chronic disease management system is also investigated.Methods: A randomized pilot trial comparing intervention group(mHealth care)and control group(usual care)was previously conducted.Trial duration was 6 months.The mHealth care including blood pressure and other physical condition management,diet management and offline health lectures.The questionnaire included the demographic characteristics of the subjects,diagnosis and treatment of chronic diseases,health behaviors,food consumption,and physical activity.The researchers whom after training asked the subjects one-to-one and filled in the electronic questionnaire.Then checked and proofed the data by two researcher independently.After the intervention,the independent sample t test was used to compare the difference in blood pressure and other body measurements between two groups.The chi-square test compared the differences in the health behavior between the two groups.One-way ANOVA analysis of different frequency in mHealth care for blood pressure and other body measurements.Regression model was established to predict different index in the trial.Results: After 6 months follow-up,the DBP increased to 1.35 ±14.74 mmHg,the body weight increased to 0.39 ± 5.84 kg in the intervention group,5.28 ±11.36 mmHg and 1.81 ±2.53 kg in the control group.The DBP and body weight in the intervention group were better than the control group.The difference was statistically significant(P<0.05).The visceral fat grade in the intervention group decreased to 0.25 ±1.65,while that in the control group increased to 0.44 ±1.55.The improvement of visceral fat grade in the intervention group was better than that in the control group(P<0.003).After the intervention,drinking in the intervention group was lower than that in the control group(P< 0.026),but there was no significant difference in other healthy behaviors between two groups.The frequency of mHealth care was divided into stopped early,stopped moderately and consecutive over long term.Except blood pressure,there was no significant difference among the three different use frequencies in other body measurements.The regression results showed that SBP depress 10.115mmHg(95% CI-16.746 ~-3.484)in the consecutive over long term group than stopped early group.There was no significant difference between the stopped moderately group and stopped early group.The self-feeling health status of the intervention group was significantly different from that of the control group(P< 0.05).52.6% of the patients in the intervention group thought that the mobile medical chronic disease management system was very useful.Self-perception of health status and willingness to continue to participate in the study in the intervention group were significantly different between control group(P<0.05).52.6% in the intervention group considered the mobile healthl chronic disease management system to be very useful.Conclusion:The mobile health chronic disease management system based on wearable device can control patients with hypertensive and diabetic the blood pressure and body weight.The different frequency of mHealth care is associated with improved blood pressure control.Maintaining consecutive over long term frequency is helpful for blood pressure control.But further research is required to confirm that the duration and pattern of mHealth care is related to the effect of blood pressure control.
