Lammers N, et al. - Researchers examined whether there was an association between serum measures of iron stores and restless legs syndrome in young adults in the community. For this investigation, study participants in the Western Australian Pregnancy Cohort (Raine) Study answered questions on restless legs syndrome at age 22 years and gave serum measures of iron stores (ferritin and transferrin saturation) at ages 17 and 22 years. In this cohort, no correlation was found between restless legs syndrome at 22 years and iron stores at 17 or 22 years. In young adults in the community, serum iron stores might not be a valuable indicator of restless legs syndrome risk.
