The association between weight misperception and weight-related behaviors among U.S. adults with overweight and obesity.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWeight misperception arises when there is a difference between an individual's actual weight and their perceived weight status. This study aimed to determine associations between weight misperception and weight-related behaviors in individuals with overweight and obesity.
methodsThe study utilized 2017-2020 data from the National Health and Nutrition Examination Survey (NHANES). Adult participants who answered the "How do you consider your weight?" question were included in the analysis. Adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were calculated using weighted logistic regression models to estimate associations between weight-related behaviors and weight misperception.
resultsThe study included 4,608 participants, of whom 1,155 (25.1%) misperceived their weight status. Weight misperception was highest among males (65.7%), young adults (33.9%), and non-Hispanic white individuals (56.3%). Multivariable analysis revealed that females were less likely than males to misperceive their weight (aOR: 0.32 [95% CI: 0.27-0.38]). Participants with higher incomes (aOR: 0.73 [95% CI: 0.56-0.95]) and obesity (aOR: 0.11 [95% CI: 0.09-0.13]) had lower odds of misperception. Conversely, Hispanic (aOR: 1.47 [95% CI: 1.16-1.86]), non-Hispanic Black individuals (aOR: 2.4 [95% CI: 1.86-3.11]), and single participants (aOR: 1.37 [95% CI: 1.14-1.63]) had higher odds. Weight misperceivers were significantly less likely to have attempted weight loss (aOR: 0.28 [95% CI: 0.23-0.33]) and engaged in weight-related behaviors, as compared to those with accurate weight perception.
conclusionsLower engagement in weight-related behaviors was associated with weight misperception, highlighting the importance of awareness of actual weight for effective obesity interventions.
