Overweight, obesity, and body weight perception among Czech adolescents: a two-decade analysis, HBSC study 2002-2022

The 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.
