THE NCHS has removed all NHANES Lab 21 “Volatile Organic Compounds” data files. The files were removed because of errors in identifying the results that were below the limit of detection, and in the fill values used for results that were below the limit of detection. A corrected data set will be released in October 2006.

This ERS publication, from the USDA, profiles participants in the NSLP. The data was collected from the 2001 SIPP and the 1999-2002 NHANES.

The recently acquired Dietary Interview files for the NHANES 2003-2004 Examination Component have been added to the PRI NHANES 2003-2004 SodaPop Collection.
