The institute of Medicine Equation was published in September 2002. It is the equation which is behind the 2005 Dietary Guidleines for Americans and the new food pyramid, MyPyramid.
The Institute of Medicine equation uses a different approach to most others. The equation doesn't measure BMR, but uses experiments based on doubly labelled water. The scientists at the institute of medicine said in their report that the factorial method tended to underestimate calorie expenditurewhen using the factorial method.
Boys Age 3-18: <math>EER=88.5-(61.9*Age)+PA*((26.7*wt)+(903*ht))</math>
Girls Age 3-18: <math>EER=135.3-(30.8*Age)+PA*((10*wt)+(934*ht))</math>
Toddlers aged 2: <math>EER=(89*wt)-80</math>
These equations are for healthy weight children and adults. Correction formulae are used for overweight and obese individuals. These corrections for children and adolescents have been debated by S. J. Woodruff, R. M. Hanning, and S. I. Barr in a paper in Obesity Reviews published January 1 2009. The issue is whether or not the different formulae are actually necessary or possibly even harmful if overestimate occurs and thus contributes to an even higher and unhealthier body weight in these individualsWoodruff, S. J., Hanning, R. M., & Barr, S. I.... Read More
