Background

Mobile weight loss interventions using smartphone applications have recently shown promising results. This study aimed to explore the efficacy of a multidisciplinary approach using mobile intervention accompanied by conventional healthcare assets, including a local public health center and regional hospital obesity clinic.

Methods

A total of 150 overweight or obese adults signed up to complete an 8-week anti-obesity intervention program with human coaching through a mobile platform. Paired t-tests and multiple linear regression analysis were used to identify the intervention factors related to weight change.

Results

Among the 150 participants enrolled in this study, 112 completed the 8-week weight loss intervention. Weight, body mass index, waist circumference, fat mass, and fat percentage all showed a statistically significant decrease and MET showed a statistically significant increase after intervention. In multiple linear regression analysis, age (ß = 0.07, P = .06), △MET (ß = −0.0009, P = 0.10), number of articles read (ß = −0.01, P = .04), and frequency of weight records (ß = −0.05, P = .10) were identified as significant factors of weight change. Moreover, age (ß = 0.06, P = .03), sex (female; ß = 1.16, P = .08), △MET (ß = −0.0009, P < 0.001), and number of articles read (ß = −0.02, P < .001, R2 = 0.3728) were identified as significant variables of fat mass change.

Conclusions

The multidisciplinary approach, combining a mobile healthcare application by healthcare providers, was effective for short-term weight loss. Additional studies are needed to evaluate the efficacy of mobile healthcare applications in obesity treatment.
