ABSTRACT

Background:

There is growing interest in mobile technology for obesity management. Despite the known effectiveness of workplace-based weight loss programs, there are few studies of smartphone-delivered intervention.

Objective:

Development and verification of an integrated and personalized mobile technology-based weight control program, optimized for workplaces.

Methods:

A weight reduction algorithm was developed for calorie prescription, continuous monitoring, periodic feedback and re-evaluation, goal re-setting, and offline intervention with behavior-changing strategies. 30 obese volunteers (BMI ≥25kg/m2) participated in a 12-week Health-On pilot program. The primary outcome was weight reduction, and secondary outcomes were improved anthropometric measures, metabolic profiles, and fat CT measures, all assessed pre- and post-intervention.

Results:

Health-On incorporated proprietary algorithms and several strategies intended to maximize adherence, using compatible online and offline interventions. The median body weight of the 30 participants decreased from 81.3kg (Interquatile range (IQR)77.1-87.8) before intervention to 76.6kg (IQR70.8-79.5) after the 12week intervention period(p<0.001). The metabolic profiles and fat measures (blood pressure, HbA1c, total cholesterol, triglyceride, HDL, LDL, ALT, visceral and subcutaneous adipose tissue; p<0.05) also improved significantly.

Conclusions:

These findings indicate that Health-On is an effective weight loss program, easily implemented in workplaces.
