%X <B>OBJECTIVE: </B>We aimed to investigate the frequency of vitamin C deficiency scurvy in the Australian paediatric context, describe cohorts at risk, and identify factors associated with development of symptoms in children with vitamin C deficiency. We also aimed to propose a management guideline for children with features of scurvy.<BR><B>METHODS: </B>A retrospective study was done at a tertiary paediatric hospital in Australia over a three-year period, from August 2019 to July 2022. Children from birth to 18 years old, whose vitamin C levels were low (<23 μmol/L), were included. Data extracted from hospital medical records included demographics, weight, co-morbidities, eating disorder diagnoses, clinical features, investigations and treatment. Descriptive statistics and risk statistics were performed.<BR><B>RESULTS: </B>In a cohort of 887 patients who had their vitamin C levels checked, we identified 272 (31%) who had a vitamin C level <23 μmol/L. Of these, 13 (5%) were symptomatic of vitamin C deficiency and 19 (7%) may have been symptomatic. In patients with vitamin C deficiency, 248 (91%) had comorbidities, neurodevelopmental disorders being most common, and 176 (65%) had restricted eating. When the asymptomatic and symptomatic groups were compared, in the symptomatic group, there was a significantly lower vitamin C level and disordered eating related to autism spectrum disorders was more common.<BR><B>CONCLUSIONS: </B>In order to avoid delayed diagnoses and unnecessary investigations, clinicians should be familiar with symptoms of scurvy and perform a dietary assessment, vitamin C assay, and commence empiric vitamin C supplementation where appropriate.
