In a cross-sectional study of 701 individuals ages 50-89 years to assess the prevalence and severity of Restless Legs Syndrome (RLS), investigators report that the serum iron, transferrin and ferritin were similar in RLS and non-RLS patients, but the soluble transferrin receptor (sTR) concentrations were higher in subjects with and without RLS. Female sex and high sTR independently predicted the risk of RLS. A high sTr indicates increased iron turnover.
