BACKGROUND
Traditional Chinese Medicine (TCM) theories assert that body constitution and meridian energy lay the foundation for disease prevention. TCM-based health concepts have not been incorporated into the mHealth app for persons with prediabetes.
OBJECTIVE
The study aimed to examine the effectiveness of a TCM mHealth app for individuals with prediabetes.
METHODS
This randomized controlled trial recruited 121 individuals with prediabetes at a teaching hospital in New Taipei City between February 2020 and May 2021. The participants were randomly assigned to TCM mHealth app (n=42), ordinary mHealth app (n=41), or control group (n=38). The ordinary mHealth app included physical activity (PA), diet, disease education, and individual records. The TCM m-Health app additionally included qi and body constitution as well as constitution-based PA and diet advices. The control group did not receive apps. Data were collected at baseline, the end of the 12-weeks intervention, and 1 month after the intervention. Body constitution was measured by the body constitution questionnaire, which yielded yang-deficiency, ying-deficiency, and phlegm-stasis, with higher scores indicating a greater deficiency. Meridian energy was examined by using the Meridian Energy Analysis Device. The Short-Form 36 was used to evaluate health-related quality of life (HRQOL), which yielded physical component scores (PCS) and mental component scores (MCS), with higher scores indicating better physical and mental aspects of HRQOL, respectively.
RESULTS
Compared to the control group, the TCM mHealth app group had a significant improvement after the intervention in yang-deficiency ( =-3.15, P=.04) and phlegm-stasis ( =-3.45, P=.04) body constitution, bladder ( =10.79, P =.02) and gallbladder meridian energy ( =13.10, P =.01), PCS ( =4.93, P=.001), and MCS ( =8.11, P<.001). They also improved greater in HbA1c ( =-0.11, P =.03), body mass index (BMI, =-0.37, P =.04), small intestine meridian energy ( =16.38, p=.04), phlegm-stasis body constitution ( =-3.30, P =.02), PCS ( =4.89, P=.001), and MCS ( =7.26, P<.001) at 1 month after the intervention compared to the control group. The ordinary mHealth app group had a greater increase in MCS ( =4.63, P =.02) at the end of intervention compared to the control group.
CONCLUSIONS
The TCM mHealth app can be used in health management for individuals with prediabetes to improve their blood sugar control, BMI, body constitution, meridian energy, and HRQOL.
