A scalable, mobile phone base intervention designed to slow weight regain after an initial weight loss had no significant effect on participants’ weight, according to a study publish this week in PLOS Medicine by Falko Sniehotta from Newcastle University, UK and colleagues.
Effective behavioral weight loss
Obesity is a major contributor to preventable life-years lost worldwide; so while effective behavioral weight loss interventions are available, weight loss is often follow by weight regain. In the new study, researchers carry out a randomize control trial involving 288 people from North East England with obesity who had recently lost at least 5% of their body weight.
The NULevel intervention consist of a single face to face goal-setting meeting; also self-monitoring, and personalized feedback on weight, diet, and physical activity via SMS text messages with embed links. The control group received standard lifestyle advice via newsletter.
Overall, 264 participants completed the trial. Those participating in the intervention group weigh themselves more frequently and were more physically active. However, the mean weight gain over the 12 month study period was similar in the two groups; hence with an average of 1.8 kg (95% CI 0.5 to 3.1) gain in the intervention group and 1.8 kg (95% CI 0.6 to 3.0) gain in the control group. The data suggest that the intervention is unlikely to be consider cost effective in its current form.
Intervention over the active
They conclude that the incremental dose of the NULevel intervention; hence over the active control condition might have insufficient to affect weight outcomes,” the authors say. This research should inform future intervention; so design decisions regarding delivery modality and intensity.
In conclusion, among individuals with obesity; so they find no evidence of effectiveness of a remotely deliver; so low-intensity behavioural intervention base on self-regulation theory in reducing weight regain; hence compare to standardize lifestyle advice and independently achieve; so clinically significant weight loss for individuals who receive a set of wire lessly connect weighing scales.
The NULevel intervention improve various hypothesize mediators compare to the control arm; so including physical activity and self-weighing; but no differences in WLM. They conclude that the incremental dose of the NULevel intervention over the active control condition; hence might have insufficient to affect weight outcomes. This research should inform future intervention design decisions regarding delivery modality and intensity.
