Abstract

Objective Text-messaging shows promise as a health intervention. This randomized controlled trial evaluated a daily text-messaging weight loss intervention.Methods Overweight and obese adults (n=170) in California were randomized to receive daily interactive and personally weight-relevant text-messages or monthly e-newsletters. Participants were measured at baseline, 6 and 12 months. Group differences were assessed in weight loss. Relation of text-messaging adherence to weight loss and change in pedometer steps was examined.Results There were no group differences in weight loss over 6 (1.53 lb vs 3.72 lb) or 12 months (2.27 lb vs 3.64 lb; control vs intervention). Text-messaging adherence was moderately strong (60-69%). Participants with greater adherence lost more weight at 6 (p=.039) and 12 months (p=.023) than those who were less adherent. Intervention participants' steps increased almost 3000 steps/day over time (p<.05), and higher step counts were associated with greater weight loss (p<.05). Text-messaging satisfaction was moderate to high, and pedometer-related satisfaction was associated with greater weight loss (p<.05).Conclusions Although text-messaging had no effect on weight, adherence was associated with improvement in weight-related behaviors and weight outcomes. Text-messages could be a useful adjunct to weight loss treatments.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There have not been any RCTs of a smartphone app as a weight loss intervention in itself using both self-monitoring and text-messaging functions.

    “Although there have been RCTs using text-messaging interventions for weight management, PDAs for self-monitoring and smartphone apps as adjuncts to other weight management interventions, to our knowledge there have not been any RCTs of a smartphone app as a weight loss intervention in itself using both self-monitoring and text-messaging functions.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
