Abstract

Objective This study investigated changes in the quality of life of men and women who participated in a primary care-based weight loss intervention program.Methods Participants were enrolled in a 2-year randomized clinical trial (POWER-UP) conducted at the University of Pennsylvania and in six affiliated primary care practices. Inclusion criteria included the presence of obesity (body mass index of 30-50 kg m(-2)) and at least two components of the metabolic syndrome.Main outcome measures Quality of life was assessed by three measures: the Short Form Health Survey (SF-12); the Impact of Weight on Quality of Life-Lite; and the EuroQol-5D.Results Six months after the onset of treatment, and with a mean weight loss of 3.9 ± 0.3 kg, participants reported significant improvements on all measures of interest with the exception of the Mental Component Score of the SF-12. These changes remained significantly improved from baseline to month 24, with the exception of the EuroQol-5D. Many of these improvements were correlated with the magnitude of weight loss and, for the most part, were consistent across gender and ethnic group.Conclusions Individuals with obesity and components of the metabolic syndrome reported significant improvements in most domains of the quality of life with a modest weight loss of 3.7% of initial weight, which was achieved within the first 6 months of treatment. The majority of these improvements were maintained at month 24, when participants had lost 3.0% of their weight.

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

  • In all but four studies over 90% of the women were white.

    “In all but four 40 , 42 , 43 , 44 over 90% of the women were white. 2 , 3 , 33 , 34 , 38 , 39 , 51”

    From Positive psychological well-being in women with obesity: A scoping review of qualitative and quantitative primary research (2022) · cites this paper as [40]

    The Results, under “Participants’ Baseline Characteristics” (page not available), report that 311 of 390 participants were women and approximately 60% of all participants were European-American. Even if every European-American participant were a woman, fewer than 90% of the women could have been white. The paper therefore contradicts the attributed proportion for this study. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

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.
