Iron deficiency (ID) is the most common nutritional deficiency with an estimated prevalence of 15,6% in France in 2006. No study has yet focused on general practitioners (GP) practice in ID screening. We performed an observational descriptive multicenter study to describe the biomarkers used by GP in ID screening, to determine ID prevalence rate among patients screened by their GP, to analyze main factors associated with iron tests prescriptions, and to analyze main factors associated with ID. ID prevalence was 39% (95% CI: 31- 47). Our study shows an inadequate use of TSAT, as well as a lack of consideration by GPs for underlying diseases and risk factors known to be associated with ID.
