Metabolic Equivalent (MET) Values for Activities in the 2002 Census Occupational Classification System (OCS)

This Web site is a companion piece to the paper:

Tudor-Locke C, Ainsworth BE, Washington TL, Troiano R. Assigning metabolic equivalent values to the 2002 census occupational classification systemExternal Web Site Policy. J Phys Act Health 2011 May;8(4):581-6.

It contains, and provides a searchable interface to, Tables 3 through 24 referenced in that article. Tables 1 and 2 are contained within the article itself.

The MET values presented on these tables and in the original article are to be used expressly for analysis of Occupational Classification System data. While they are based on the Compendium of Physical Activities, the MET levels differ from those in the Compendium due to combining activities and their associated MET levels in the OCS.

For consistency in assigning intensity values to physical activity questionnaires, researchers should use the MET values presented in the Compendium of Physical ActivitiesExternal Web Site Policy.
