Vitamin D3 Levels Not Linked to Academic Achievement
Vitamin D<sub>3</sub> Levels Not Linked to Academic Achievement
(HealthDay News) – Serum 25-hydroxyvitamin D (25[OH]D)3 concentrations are not associated with academic performance in children.
To investigate the association between serum 25(OH)D concentrations and academic performance, Anna-Maija Tolppanen, PhD, of the University of Bristol in the United Kingdom, and colleagues conducted a prospective cohort study involving 3,171 children. Serum 25(OH)D3 and 25(OH)D2 concentrations were measured at a mean age of 9.8 years, and academic performance was assessed at age 13–14 years and 15–16 years.
The researchers found no correlation between serum 25(OH)D3 concentrations and any educational outcomes. Higher concentrations of 25(OH)D2 correlated with worse performance in English at age 13–14 years and with worse academic performance at age 15–16 years.
"Our findings do not support suggestions that children should have controlled exposure to sunlight, or vitamin D supplements, in order to increase academic performance," the authors write.
