Abstract

Purpose: This study aimed to examine the preliminary effect, feasibility, and acceptability of a lifestyle intervention program using a mobile application (app) versus the effect of a program using a booklet for adults with metabolic syndrome (MetS). Patients and Methods: This trial was conducted in two community centers of Hong Kong. Participants were included if they were adults with MetS, aged over 50, and able to use a smartphone. Eligible subjects were randomly assigned to either the app group or booklet group. Those in the booklet group received a health talk and a booklet, whereas those in the app group received a health talk and a MetS app to support their exercise maintenance and health records for 3 months. Both groups received similar educational content related to healthcare for MetS clients. Data were collected at baseline (T1) and at 1-(T2) and 3-month (T3) intervals. Outcomes were body weight (primary outcome), total amount of exercise, blood pressure, and lipid concentrations. Data were analyzed using the generalized estimat-ing equation models. Feasibility and acceptability were assessed in process evaluation. Results: Ninety-eight individuals were screened for eligibility and 77 were randomized into the app group (n = 38) or booklet group (n = 39). The attrition rate at T3 was 11.690%. The app group showed a significant reduction in body weight (β = −1.069, p = 0.012) and body mass index (β = −0.371, p = 0.026), a greater amount of exercise (β = 8.454, p = 0.032), and improved exercise self-efficacy (β = 10.62, p = 0.001) within 3 months. There were no significant differences between groups for other outcomes. The participants appreciated the proposed intervention of the programme. Conclusion: The MetS app may be incorporated in the health promotion programme to support exercise maintenance and a healthy lifestyle in the community.
