Mobile health behaviour change support system as independent treatment tool for obesity: a randomized controlled trial
Authors' conclusion
The mHBCSS as a stand-alone treatment of obesity results in weight reduction and weight loss maintenance with remarkable adherence rate. Further studies are needed to establish how to best implement the scalable and resource-efficient mHBCSS into the standard care of obesity to achieve optimal weight loss results.
Study context
- Population
- Volunteers with obesity (BMI 30–40 kg/m² and age 18–65 years); 88.5% women, mean BMI 34.3 kg/m² (SD 2.8), age 46.5 years (SD 9.5)retention 98.5% at 6 months
- Participants
- 200 volunteers
- Comparison
- Immediate access to mobile health behaviour change support system (mHBCSS) vs wait-list control
- Primary endpoint
- Weight loss from baseline
- Follow-up
- 6 months
Methodological detailswait-list controlled

Primary result
As reported in the abstract
Weight change from baseline
mHBCSS
−2.5%
95% CI −3.4–-1.6
Wait-list control
0.2%
95% CI −0.4–0.9
Between groups p < 0.001
Further findings
- Weight change from baseline (maintenance) · 12 months — mHBCSS
- −2.1% (95% CI −3.3–-0.9)
- Weight change from baseline (maintenance): p = 0.001
Metabolic traits
- No significant effect of mHBCSS usage on metabolic traits
Retention rate · 12 months
- Retention at 12-month visit
- 89.0%
