Health risk assessment requires the use of human exposure variables (HEVs, also known as exposure factors [EFs]) during the exposure characterization stage. To ensure that the results are more specific to the French population, it is necessary to use French data. Currently, few data suitable for deterministic and probabilistic health risk assessments are available. A previous study by the French Institute for Public Health Surveillance (InVS) in 2007 proposed a body mass distribution based on the 2002–2003 ten-year study by the National Institute of Statistics and Economic Studies (INSEE). This article proposes an update of the description and distribution of body mass for the French population based on the Study on Health, Environment, Biomonitoring, Physical Activity, and Nutrition (Esteban), whose data were collected between 2014 and 2016. The results are presented here to facilitate their use by risk assessors (results by school age group for children and results for men and women analyzed separately and together). [authors’ abstract]
