Vitamin E Inadequacy Observed in a Group of 2- to 6-Year-Old Children Living in Kwangju, Republic of Korea
Bibliographic record
Abstract
Studies on the vitamin E status of Korean children are lacking. Dietary intakes and plasma concentrations of tocopherols of healthy 2- to 6-year-olds living in Kwangju, Republic of Korea, were determined and their vitamin E status evaluated. Subjects included 66 girls and 65 boys, with 21–32 subjects per age group. Subjects’ intakes were recorded by a trained interviewer for foods eaten at preschool/kindergarten; otherwise, three consecutive 24-hour food recalls were obtained from parents. Plasma tocopherol concentrations were determined using high-performance liquid chromatography. Intakes of energy and total monounsaturated and polyunsaturated fats were significantly different (p < 0.05) among age groups, not gender, with 2- and 3-year-olds having lower intakes. Alpha- and γ-tocopherol intakes were similar by age and gender. Sixty-seven percent consumed less than the Korean Adequate Intakes for vitamin E, and 77% had α-tocopherol intakes less than USA/Canadian Estimated Average Requirements. Plasma α-tocopherol concentrations, but not γ-tocopherol, were significantly higher (p < 0.05) for 2-year-olds. Two-thirds of subjects had plasma α-tocopherol concentrations less than 12 μmol/L, which is indicative of vitamin E inadequacy in adults; guidelines for children do not exist. Many of the Korean children had inadequate intakes and likely inadequate plasma concentrations of vitamin E.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
