Data Release

Updated Data

URXUCR was updated to correct the Limit of Detection, only six data points were affected.

2013-2014 Aldehyde – Serum datasets (ALD_H & ALDS_H) were updated to correct the Limits of Detection (LOD) for various analytes in the LOD table in both documentation files. However, only data for one analyte (LBXI5AL-Isopentanaldehyde)was updated, as the LOD was corrected from 0.119 ng/mL to 0.316 ng/mL.

Documentation and SAS labels for the following pooled-sample datasets were updated to reflect the correct units the analyte values were reported in. No changes were made to the actual values of any analytes in these datasets.

Updated Data

2011-2012 Oral Health – Dentition File (OHXDEN_G) was updated to provide the 2011-2012 dental fluorosis clinical assessment data in a separate dataset (FCXCLN_G) to be consistent with the release of the 2013-2014 and 2015-2016 data. Variables for the 2011-2012 fluorosis data were renamed to reflect the new file name (i.e., prefix changed from OHX to FCX). There were no changes to any data values. There were no changes to any variables remaining in the 2011-2012 Oral Health – Dentition file.

 

March 2019

Updated Data

The SSANA_A, SSANA_B and SSANA_C are combined into one 6-year dataset SSANA_A with a set of 6-year weight attached.

TFA_A was updated to add data points for children 6-19 years.

TFA_F was updated to add data points for children 3-19 years.

Data Release

Updated Data

2011-2012 folate and folate form datasets were updated to correct a calibration bias in the serum folic acid determination. Please refer to the analytic notes in the documentations accompanying the datasets for more details.

2007-2008 serum folate forms dataset was updated to: 1) add two comment code variables (LBDSF1LC, LBDSF2LC) documenting cases with values below lower detection limit, these variables were inadvertently omitted from original release; and 2) rename two folate form variables as “LBXSF1SI” and “LBXSF2SI” to reflect the SI unit (nmol/L) of their values, no changes were made to the actual values of these two variables.

GLU_I dataset was updated to round the LBXGLU variable to the nearest whole number.

Documentation for the Volatile Organic Compounds (VOC) datasets in three earlier cycles were updated. 2001-2002: References were added; and 2003-2004 & 2005-2006: units of measurement for MTBE and Trihalomethane analytes were corrected to pg/mL. No changes were made to any data points in these datasets.

Updated Data

  • The documentation for the 1999-2016 Demographic Variables & Sample Weights files was updated to include information on weighted mean age for NHANES participants in the top-coded age group.
    No changes were made to any data points in these datasets.
  • Human Papillomavirus (HPV) DNA – Vaginal Swab: Digene Hybrid Capture & Roche Linear Array datasets in the 2005-2006 cycles (HPVSWR_D
    and SWR_D_R) were updated to add two variables (LBXH2RL-Hybrid Capture high risk result and
    LBXH3RL-Hybrid Capture low risk result) inadvertently omitted from the original release.
  • Laboratory method files inadvertently omitted from the original release for 2003-2012 human papillomavirus (HPV) vaginal swab and serum datasets were added.
  • The documentation for the pooled-sample environmental exposure laboratory datasets in the 2005-2006 and 2007-2008 cycles has been updated to include a Limit of Detection (LOD) table. No changes were made to any data points in these datasets.
