Overweight, obesity, and body weight perception among Czech adolescents: a two-decade analysis, HBSC study 2002-2022.
Article in Central European journal of 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
objectivesExcess body weight and weight misperception in adolescents are associated with various physical and mental health risks. This study analysed trends in overweight, obesity, body image, and body weight perception among Czech adolescents between 2002 and 2022, considering gender, age and socioeconomic status (SES).
methodsData were retrieved from the questionnaire of the Health Behaviour in School-aged Children (HBSC) study conducted in 2002, 2006, 2010, 2014, 2018 and 2022 (N = 52,363; 49.9% girls). The difference test between two proportions was used to assess time trends in weight status (WS), body image and body weight perception across gender and SES groups. Logistic regression analysis was performed to examine the likelihood of being overweight/obese, and underestimating or overestimating WS.
resultsBetween 2002 and 2022, overweight and obesity increased significantly, while non-overweight rates declined across both genders and SES groups, with a greater rise among boys and adolescents from low SES backgrounds. In 2022, more adolescents, regardless the gender and SES, perceived their body as "too thin" compared to 2002. Over the 20-year period, underestimation of WS increased while overestimation decreased among both girls and boys and across all SES groups. Accurate perception of WS rose among girls but worsened among boys. Girls were less likely than boys to be overweight/obese or to underestimate their WS but had higher odds of overestimating it.
conclusionsThe significant rise in overweight and obesity, especially in boys and adolescents from low SES backgrounds, during the last 20 years points out to socioeconomic disparities and should be taken into account when creating new policies. An improvement in correct perception of WS among girls and a decline in overestimating WS across genders and SES groups could help reduce risks of developing mental health problems/eating disorders. Conversely, an increase in underestimation of WS may contribute to weight-related health risks.
