INTRODUCTION: Formaldehyde (FA) is currently classified as a known carcinogen. In addition to being a ubiquitous compound with many common exogenous exposure sources, it is also part of multiple metabolic pathways and present in every living cell. The objectives of this study were to determine normative levels of FA as measured by FA-Hemoglobin (Hb) adducts in the United States (US) and to determine if FA-Hb levels differ based on a variety of demographic factors.
METHODS: Data collected between 2013 and 2016 by the National Health and Nutrition Examination Survey were assessed from 4521 participants representing approximately 244 million individuals living in the US. General linear models were used to examine associations between FA-Hb adducts and sample characteristics. FA-Hb levels were summarized using geometric mean concentrations (GMC) and associated 95% confidence intervals (CI).
RESULTS: The overall GMC was 131.10 nmol/g Hb (95% CI 129.39-132.83). Analyses revealed no evidence to support associations between FA-Hb levels and age, gender, income, or nicotine use. Among adults, non-Hispanic Black race was associated with lower FA-Hb levels compared to all other race/ethnicity groups, P < 0.01.
CONCLUSION: The study provides the first normative values for FA in adults and children. These data could be a tool to assess the body's response to acute and chronic exposure.
