The decision to measure or to ask about data concerning height and weight in order to calculate body mass index (BMI) has an influence on the economy and validity of the measurements. Although self-reported information is less expensive, this information may possibly have a bias on the determined prevalences of different weight groups. Using representative data from the KiGGS study with a comparison of directly measured and self-reported BMI data, Kurth and Ellert (2010) developed two correction formulas for prevalences resulting from self-reported information. The aim of the study was to examine the practicability of the proposed correction formulas on our own data concerning self-reported BMI data of 11- to 13-year-old girls (n=1,271) and to assess the plausibility of the corrected measurements. As a result, the prevalences of our own data changed in the expected direction both for underweight and for overweight. Both formulas were found to be practicable, the consideration of the subjective weight status (formula 2) resulted in a greater change in prevalences compared to the first correction formula.
