Objective To explore the effects of community-based chronic disease management based on smart wearable devices and the Internet in the health management of hypertensive patients in the community. Methods The multistage cluster sampling method was used to enroll study subjects from six communities in Nan’an District

Chongqing

from July 2018 to July 2019. Fifty eligible subjects were selected from each community

and the random number table method was used to divide the study subjects into a control group and an intervention group

150 cases each. The subjects in the control group were subjected to conventional hypertension chronic disease management in accordance with the current national regulations and requirements. The subjects in the intervention group received community-based chronic disease management based on smart wearable devices and the Internet. A self-made questionnaire was used to collect relevant information from the study subjects. Data for body composition（body composition including body mass

muscle mass

visceral fat index

bone mass

body fat percentage

body water

and body score） and blood pressure were collected before and after the intervention

and all other information was collected after the intervention. Results After 6 months of intervention

99 subjects in the intervention group completed follow-up and 102 subjects in the control group completed follow-up. The difference between the two groups in this regard was not statistically significant（P>0.05）. The difference between the two groups was statistically significant（P<0.05） when comparing general information like age

height

and education level. The body mass and body mass index of subjects in both groups were higher than those before the intervention

and the differences were statistically significant（P<0.05）. The net effect of the intervention on body mass

blood pressure

and body composition was analyzed using double-difference regression

and the results showed that the net effect in the intervention group was a significant reduction in body visceral fat index scores compared to the control group（P<0.05）. It was also seen that the net effect of the intervention in changing body mass

blood pressure

muscle mass

bone mass

body fat percentage and body score in the 2 study groups was not statistically significant（P>0.05）. Conclusion The community-based chronic disease management approach based on smart wearable devices and the Internet has an adjunctive effect on hypertension control

especially in changing visceral fat index scores in hypertensive patients

and in-depth studies should be conducted in the future to clarify its long-term effects and cost-benefit ratio.
