Ascorbic acid status of children with developmental disabilities.

N S Springer

    Journal of the American Dietetic Association
    |October 1, 1979
    PubMed
    Summary

    Children with developmental disabilities generally had adequate ascorbic acid intake, but some showed low serum levels and impaired vitamin C metabolism. Further research into nutrient status is warranted.

    Area of Science:

    • Nutritional biochemistry
    • Pediatric health

    Background:

    • Assessing ascorbic acid status in children with developmental disabilities is crucial for understanding their nutritional needs.
    • Dietary intake and biochemical markers provide a comprehensive view of vitamin C levels.

    Observation:

    • Thirty-nine children (ages 3-19) with developmental disabilities were evaluated for ascorbic acid status.
    • Dietary records indicated high mean intakes (204% of allowance), but biochemical tests revealed varied results.
    • Fasting serum levels averaged 1.3 mg/dL, with only two children showing unacceptable deficiency.

    Findings:

    • Ascorbic acid load tests identified low, moderate, and high urinary excretors.
    • Children with low dietary intake (<66% allowance) were more likely to have deficient serum levels and poor urinary recovery.
    • Normal children consistently demonstrated high excretion rates post-load test.

    Implications:

    • While average intake appears sufficient, a subset of children with developmental disabilities may still experience vitamin C deficiency or impaired metabolism.
    • Biochemical assessment is vital for identifying subclinical deficiencies not evident from dietary records alone.
    • These findings highlight the need for individualized nutritional monitoring in this population.
