Vitamin B-6 Inadequacy Is Prevalent in Rural and Urban Indonesian Children
Abstract
The vitamin B-6 status of Indonesian children was evaluated by determining their dietary vitamin B-6 intakes, erythrocyte alanine aminotransferase activity coefficients and plasma pyridoxal phosphate (PLP) concentrations. Thirty-eight third-grade elementary school children (ages = 8–9 y) in rural and 39 in urban areas of Bogor, West Java, Indonesia, voluntarily served as subjects. The subjects included 39 male and 38 female students. The mean vitamin B-6 intake of the subjects was 0.57 mg/d. Fifty-five percentage of the children reported consuming <0.5 mg/d of vitamin B-6 (the 1998 Estimated Average Requirement for those 4–8 y). Erythrocyte alanine aminotransferase activity coefficients 1.25 were observed in 30%, and plasma PLP concentrations 30 nmol/L were observed in 25%; these values are considered indicative of vitamin B-6 inadequacy. Similar percentages of male and female subjects had inadequate vitamin B-6 status. Significantly more (P < 0.05) rural children than urban had inadequate vitamin B-6 status as assessed by the three indices. Vitamin B-6 inadequacy was found to be prevalent among these Indonesian children, especially those living in rural areas. ________________________________________ KEY WORDS: • vitamin B-6 status • alanine aminotransferase • plasma PLP • Indonesian children
