Impact of an Internet‐Based Lifestyle Intervention on Behavioral and Psychosocial Factors During Postpartum Weight Loss
Open accessAbstract
Objective: This cluster randomized trial tested whether an effective internet‐based weight‐loss intervention for low‐income, postpartum women resulted in greater improvements in targeted social cognitive theory (SCT) constructs and psychosocial outcomes. Methods: Fit Moms/Mamás Activas was a 12‐month cluster randomized controlled trial of 370 postpartum women at 12 Special Supplemental Nutrition Program for Women, Infants, Children (WIC) clinics that were randomly assigned to intervention or standard WIC. SCT constructs (weight‐control behaviors, cognitive restraint, disinhibition, self‐efficacy, social support, body image) and psychosocial outcomes (depressive symptoms and stress) were measured at study entry and after 6 and 12 months. Results: The intervention versus standard WIC resulted in greater 12‐month increases in weight‐control behaviors (3.28 points [95% CI: 1.06‐5.50]), self‐monitoring of weight and eating (2.28 points [1.17‐3.40]), and cognitive restraint (1.93 points [0.78‐3.08]) (all P ≤ 0.004). The intervention effect was only modestly (η p2 = 0.02) mediated by improvements in these factors. No significant group by time effect was observed for disinhibition, self‐efficacy, social support, body image, depressive symptoms, or stress. Conclusions: Among low‐income postpartum women, an effective internet‐based weight‐loss program resulted in improved weight‐control behaviors and cognitive restraint but did not affect other SCT targets and psychosocial outcomes.

The majority of articles (n = 24) did not deal with the feasibility of the interventions.
“However, the majority of the articles (n = 24) did not deal with the feasibility of the interventions [20, 35, 36, 38, 40, 43–45, 47, 48, 50, 51, 56, 62, 64, 66, 67, 69, 72–77].”

The Methods and Results describe a trial assessing weight-control behaviors and psychosocial outcomes, rather than intervention feasibility. The Discussion mentions high retention but does not present a feasibility assessment. This single paper cannot establish the citing document’s aggregate count of 24 articles or that they were a majority. (LLM, conf=0.78)

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.
