Abstract

Objectives To evaluate the efficacy of an Internet behavioral weight loss program; and determine if adding periodic in-person sessions to an Internet intervention improves outcomes.Methods 481 healthy overweight adults (28% minority) were randomized to one of 3 delivery methods of a behavioral weight loss program with weekly meetings: Internet (n=161), InPerson (n=158), or Hybrid (Internet+InPerson, n=162). Outcome variables were weight at baseline and 6 months and percent of subjects achieving a 5 and 7% weight loss. The study took place in two centers in Vermont and Arkansas from 2003 to 2008.Results Conditions differed significantly in mean weight loss [8.0 (6.1) kg vs. 5.5 (5.6) kg vs. 6.0 (5.5) kg], for InPerson, Internet, and Hybrid respectively, p<0.01, n=462). Weight loss for InPerson was significantly greater than the Internet and Hybrid conditions (p<0.05). Although the proportion reaching a 5% weight loss did not differ, the proportion losing 7% did differ significantly (56.3% vs. 37.3% vs. 44.4% for InPerson, Internet, and Hybrid respectively, p<0.01).Conclusions These results demonstrate that the Internet is a viable alternative to in-person treatment for the delivery and dissemination of a behavioral weight-control intervention. The addition of periodic in-person sessions did not improve outcomes.

  • One weight loss study (Harvey-Berino 2010) compared an interactive computer-based intervention with an in-person intervention.

    “One weight loss study (Harvey-Berino 2010) compared an interactive computer-based intervention with an in-person intervention.”
  • In Harvey-Berino 2010, results were similar when percent weight change rather than kilograms change was the outcome: the computer group lost less than the in-person group (MD 2.2%, 95% CI 0.9 to 3.5; P = 0.0007; 319 participants).

    “Results were similar when percent weight change rather than kilograms change was the outcome (MD 2.2% (95% CI 0.9 to 3.5); P = 0.0007; 319 participants; Analysis 2.2; analysis 2.2.1)”
  • In Harvey-Berino 2010, there was not a statistically significant difference between intervention groups in attendance or journal submission.

    “There was not a statistically significant difference between intervention groups in attendance or journal submission, and the authors did not test for associations between attendance or compliance and weight loss within intervention groups.”
  • In Harvey-Berino 2010, when the interactive computer-based intervention group was compared to the hybrid intervention group, there was no statistically significant difference in weight loss (MD 0.2 kg, 95% CI −1.0 to 1.4; P = 0.75; 323 participants).

    “When the interactive computer-based intervention group was compared to the hybrid intervention group, there was no statistically significant difference in weight loss (MD 0.2 kg (95% CI −1.0 to 1.4) P = 0.75; 323 participants; Analysis 2.1; analysis 2.1.2).”
  • In Harvey-Berino 2010, at completion of the six-month intervention, participants in the interactive computer-based intervention group lost less weight than participants in the in-person intervention group (MD 2.1 kg, 95% CI 0.8 to 3.4; P = 0.002; 319 participants).

    “At the completion of the six-month intervention, participants in the interactive computer-based intervention group lost less weight than the participants in the in-person intervention group (MD 2.1 kg (95% CI 95% CI 0.8 to 3.4) P = 0.002; 319 participants, one trial, Analysis 2.1; analysis 2.1.1).”

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.
