Trial results for a mobile lifestyle intervention targeting overweight and obesity were posted on ClinicalTrials.gov on 2026-01-15. The gamified intervention group achieved a least squares mean weight loss of -5.3 Kg, compared to -3.49 Kg in the standard app group, with a p-value of 0.09 for the difference.
Background
Obesity and overweight are significant public health concerns, often co-occurring with conditions like Type 2 Diabetes. Achieving long-term sustained weight loss is a primary goal in managing these conditions. Digital interventions, particularly those incorporating elements like social gaming to encourage self-monitoring and social support, represent a promising approach to facilitate behavioral changes necessary for weight management. This study explored the effectiveness of such an intervention in a diverse adult cohort.
Trial design
This completed study, designated as Phase NA, enrolled 243 participants with Overweight and Obesity and Type2 Diabetes. The trial aimed to examine long-term sustained weight loss using a digital intervention. The intervention included social gaming elements to reward behaviors such as self-monitoring and social support. Participants were randomized into either a 'Gamified mLIFE App Group' or a 'Standard mLIFE App' group to compare their effectiveness.
Key results
The trial reported the following key measurements at 12 months:
- Change in Body Weight:
- Participants in the Gamified mLIFE App Group experienced a least squares mean change of -5.3 Kg (Standard Error 0.64).
- Participants in the Standard mLIFE App group experienced a least squares mean change of -3.49 Kg (Standard Error 0.72).
- Change in Energy Intake:
- The Gamified mLIFE App Group showed a least squares mean change of -347.73 Kcals (Standard Error 91.15).
- The Standard mLIFE App group showed a least squares mean change of -257.42 Kcals (Standard Error 92.93).
- Change in Weekly Moderate to Vigorous Physical Activity (MVPA):
- The Gamified mLIFE App Group showed a least squares mean change of -4.66 min/wk (Standard Error 23.45).
- The Standard mLIFE App group showed a least squares mean change of -3.5 min/wk (Standard Error 24.91).
A Mixed Models Analysis comparing the final values between groups for body weight indicated a mean difference of -1.81, with a 95.0% confidence interval ranging from -3.71 to 0.09. The p-value for this analysis was 0.09.
What this means
The results suggest that the gamified mobile lifestyle intervention led to a numerically greater reduction in body weight and energy intake compared to the standard app intervention over 12 months. While the gamified group lost 1.81 Kg more on average, the p-value of 0.09 indicates that this difference did not reach conventional statistical significance. Changes in moderate to vigorous physical activity were minimal in both groups. These findings provide insights into the potential benefits of incorporating social gaming into digital weight management programs, warranting further investigation into the long-term efficacy and clinical significance of such interventions.
