ABSTRACT: Background
The aims of the current study were to assess the nutritional status of 25OHD3 and retinol in a northern Chinese population using our established reliable method for the simultaneous determination of serum 25OHD3 and retinol.Method
We established a reliable method for the simultaneous determination of 25OHD3 and retinol using SPE and UPLC/PDA; measured the serum levels of 25OHD3 and retinol in elementary school students, middle school students, and adults (n = 1181) in northern China; and assessed their nutritional status.Results
Our method had good precision, detection limit, and linear quantitative range and could process 100 samples within 12 h. The average levels of 25OHD3 and retinol were 16.1 ± 6.7 ng/ml and 328.1 ± 117.1 ng/ml, respectively, in all samples. VD deficiency was common, with a prevalence > 60% in all three age groups, and the high prevalence of VA deficiency (26.1%) was observed only in the elementary school students.Conclusions
Vitamin A supplementation should be considered for elementary school students, and vitamin D supplementation is highly recommended for all age groups in Harbin. Our method could be widely adopted in population-based studies and clinical practice.
