Speaker Notes

Because of the numerous advantages of using BMI-for-age for assessing overweight in children and adolescents, expert committees and advisory groups have recommended BMI-for-age as the accepted measure. Published references are listed on the slide. Briefly, the background on recommendations to use BMI-for-age follow:

  • In 1994, an expert committee on Clinical Guidelines for Overweight in Adolescent Preventive Services was convened to provide advice on the development of Bright Futures: National Guidelines for Health Supervision of Infants, Children and Adolescents and Guidelines for Adolescent Preventive Services (GAPS). The committee recommended that BMI-for-age be used to routinely screen for overweight in adolescents.

  • In 1997, a consensus panel recommended that BMI for age be used routinely to screen children for overweight. They also recommended cutpoints of between the 85th and 95th percentiles to identify children and adolescents as at risk of overweight and at or above the 95th percentile to identify children and adolescents as overweight. (Barlow and Dietz, 1998).

  • Also, in 1997, an international conference convened by the International Obesity Task Force concluded that BMI is a reasonable measure for assessing overweight in children and adolescents worldwide. (Dietz and Bellizzi, 1999; Bellizzi and Dietz, 1999).
