Abstract

In this pilot study, the effects of two computer-assisted dieting (CAD) interventions on weight loss and blood chemistry were examined among overweight and obese adults. Participants (91 community members, average age 42.6 years) were randomly assigned to CAD-only (a single-session introduction and provision of a dieting software, n = 30), CAD plus an additional four-session self-management group training (CAD+G, n = 31) and a waitlist control group whose members were randomised into the two interventions at the 3-month follow-up (n = 30). A three (group)-by-two (time) repeated measures ANOVA revealed no significant group by time interaction during the initial 3-month period. However, the two intervention groups combined showed a significant, though moderate weight loss relative to the control group. Further, although a general improvement was found with regard to the lipid panel results during the first 3 months of the trial, the treatment by time interaction was not significant. A comparison of the developments in the two intervention groups during the 3- to 6-month follow-up time period revealed a tendency towards greater weight regain in the CAD-only condition. The evidence suggests that CAD supports initial weight loss; however, additional self-management training might be necessary to support maintenance.

  • Two of the studies comparing an interactive computer-based intervention with a minimal or no treatment control condition were three-arm trials, and both reported no significant difference between the two computer intervention arms.

    “Two of the studies comparing an interactive computer-based intervention with a minimal or no treatment control condition (Schroder 2010; Wylie-Rosett 2001) were three-arm trials, in which a third treatment arm supplemented the computer-based intervention with an in-person treatment component. Both studies reported that there was not a significant difference between the two computer intervention ar”

  • When the sole quasi-randomized trial (Schroder 2010) was omitted, results were similar to the initial analysis (MD -2.8 kg, 95% CI -3.7 to -1.9, P < 0.00001; 339 participants; four trials), although heterogeneity remained moderate (I2 = 31%).

    “When we omitted the sole quasi-randomized trial (Schroder 2010), which was also the only trial that included an ongoing in-support arm as one component of the computer intervention, results were again similar to the initial analysis (MD −2.8 kg (95% CI −3.7 to −1.9), P < 0.00001; 339 participants; four trials; Analysis 1.1: sensitivity analysis 1.1.2), although heterogeneity remained moderate (I2”

  • One trial (Schroder 2010) was a quasi-randomized controlled trial which assigned every third participant, hence investigators and participants could potentially have foreseen assignments and the review judged that allocation was not adequately concealed.

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.
