    Published in Sleep Medicine

    Methodology

    Observational study combining validated sleep questionnaires with wrist actigraphy in children and adolescents with documented iron deficiency.

    Key Findings

    Children and adolescents with iron deficiency showed a higher burden of parent-reported sleep disturbance and actigraphy-measured sleep fragmentation, including restless-legs-type symptoms, than reference expectations.

    Conclusions

    Pediatric ID/IDA was associated with caregiver-reported and actigraphic sleep disruption, characterized by restless and fragmented sleep.

    Limitations

    Small sample (n=31), no matched control group, cross-sectional design that cannot establish causation, and no interventional iron repletion arm.
