Twenty-two percent of the children had pyridoxine deficiency, of which 15 percent had an AC ≥ 3.37 and 7 percent had border-line deficiency (AC between 3.08-3.36). The prevalence of pyridoxine deficiency increased with age from 11 percent in the first year to 31 percent in the age range of 49-60 months.Mahidol UniversityMedicineNursingArticleSCOPUS10.1093/ajcn/41.4.770
