Prevalence of Vitamin D Deficiency in Children

摘要

Among toddlers, milk consumption significantly reduced the chance of vitamin D deficiency (odds ratio [OR] = 0.51), with each cup of milk per day increasing serum 25-hydroxyvitamin D levels by 3.1 ng per mL (8 nmol per L). No correlation was found between vitamin D deficiency and sex, time spent outdoors, sunscreen use, sun sensitivity, or skin pigmentation.
