Abstract Aim: the aim of the present study was to assess the validity of self-reported weight and height among Cypriot adolescents. Method: Adolescents’ weight and height was measured during school. Students completed the questionnaires EAT-26 and EDI-3. Results: self-reported and measured weight and height are highly correlated. Boys underreport their weight by 0.28 kg and over report their height by 0.84 cm; girls underreport their weight by 0.91 kg and over report their height by 1.52 cm. 8% of overweight adolescents would have been neglected if self-report measures were relied upon. Overweight adolescents make greater self-report errors in BMI in comparison to their normal/ underweight counterparts. Adolescents who overestimated their weight by 5% had lower scores on Drive for thinness scales and Body dissatisfaction scales. Conclusion: relying on selfreport estimates of height and weight can lead to erroneous conclusions of prevalence estimates of overweight and obesity among Cypriot adolescents and must be used with caution.
