Our objective was to estimate ID prevalence and associated sociodemographic markers in young children in France. The Saturn\u2010Inf national cross\u2010sectional hospital\u2010based survey recruited 3,831 French children &lt;6\u00a0years old between 2008 and 2009 to assess lead poisoning prevalence and to establish a biobank. This secondary analysis measured serum ferritinemia (SF) in sera kept frozen at \u221280\u00a0\u00b0C for children with sufficient serum aliquots and C\u2010reactive protein &lt;10\u00a0mg\/L. For the 657 participating children (17% of the Saturn\u2010Inf study), the median age was 3.9\u00a0years (interquartile range: 2.2\u20135.1); 52% were boys. The median SF was 44\u00a0\u03bcg\/L (interquartile range: 28\u201371). ID prevalence was 2.8% (95% confidence interval [1.7, 4.7]) and 3.2% (95% confidence interval [2.0, 5.1]) with an SF threshold of 10 and 12\u00a0\u03bcg\/L, respectively.
