Mobile health applications enhance weight loss efficacy following bariatric surgery.

INTRODUCTION: With the epidemic of obesity numerous mobile health (mHealth) applications have been designed with the goal of facilitating weight loss. This technology has the potential to focus behavioral modification in a manner that's effective for weight loss. We examined the use of this mHealth technology in our bariatric surgery population to evaluate effects on weight loss following surgery.
METHODS: Single institution prospective randomized control trial performed at an academic center. 56 patients who recently underwent a laparoscopic sleeve gastrectomy (LSG) were enrolled into a control group with standard post-operative monitoring and a mHealth application group provided with iPad© minis with the MyFitnessPal© mHealth application. Participants were followed for 24 months. The primary outcomes were effect on weight loss as determined by excess body weight loss (%EWL) and excess BMI loss (%EBL).
RESULTS: Statistically significant differences in weight loss outcomes between the groups were present throughout the duration of the study. At 12 months, %EWL was 74.41% (control) vs 81.41% (mHealth) p value 0.047 and at 24 months, it was 59.10% (control) vs 71.47% (mHealth) p value 0.0078. %EBL findings at 12 months was 28.02% (control) vs 32.15% (mHealth) p value 0.0007 and at 24 months, it was 25.39% (control) vs 27.87% (mHealth) p value 0.048.
CONCLUSION: Our results demonstrate mHealth applications are a useful adjunct to improve and maintain weight loss following bariatric surgery. We suggest mHealth applications should be utilized following bariatric surgery for improved outcomes.
