The FDA’s Center for Tobacco Products (CTP) and the NIH’s National Institute on Drug Abuse (NIDA) announce the release of the first in a series of restricted-use biomarker data files from Wave 5 of the Population Assessment of Tobacco and Health (PATH) Study collected December 2018 – November 2019. This latest addition to the PATH Study’s Biomarker Restricted-Use Files (BRUF) includes urine panel assay data files, namely urinary nicotine metabolites (UNICM), creatinine (CREAU), metals, and volatile organic compounds metabolites (VOCM). The release also includes datafiles containing urine biomarkers of oxidative stress (F2PG2a) at Wave 3. Qualified researchers may apply for access through the PATH Study Biomarker Restricted-Use Files webpage at https://doi.org/10.3886/ICPSR36840.
In addition, updates were made to the Wave 5 Public-Use File (PUF), the Wave 5 Restricted-Use File (RUF), Wave 4 BRUF, the Wave 1 – Wave 4 VOCM BRUFs. Researchers may apply to access the RUF at https://doi.org/10.3886/ICPSR36231, and the PUF can be accessed at https://doi.org/10.3886/ICPSR36498. Restricted-Use Master Linkage Files were also updated and are available at https://doi.org/10.3886/ICPSR38008.
The Biospecimen Access Program webpage at http://bit.ly/2wBFOtc provides information on how to access the urine, serum, plasma, and genomic DNA (gDNA) collected from adult PATH Study participants during Wave 1 (2013-2014) and urine collected during Wave 2 (2014-2015), Wave 3 (2015-2016), Wave 4 (2016-2018), and Wave 5 (2018-2019).
The PATH Study is a household-based, nationally representative, longitudinal cohort study of youth (12-17 years old) and adults in the United States. The study was launched in 2011 to inform FDA’s regulatory activities under the Family Smoking Prevention and Tobacco Control Act.
