Measuring the bias precision accuracy and validity of self-reported height and weight in assessing overweight and obesity status among adolescents using a surveillance system

摘要

BackgroundEvidence regarding bias, precision, and accuracy in adolescent self-reported height and weight across demographic subpopulations is lacking. The bias, precision, and accuracy of adolescent self-reported height and weight across subpopulations were examined using a large, diverse and representative sample of adolescents. A second objective was to develop correction equations for self-reported height and weight to provide more accurate estimates of body mass index (BMI) and weight status.
