Vitamin B-6 dietary intake and status of rural and urban Indonesian elementary school children
Abstract
The study was conducted in Bogor, West Java, Indonesia. Thirty-eight third-grade elementary school children (age = 8–9 y) in rural and thirty-nine in urban areas participated voluntarily. The subjects included male and female students. Food sources of vitamin B-6, commonly consumed by the subjects, were analyzed for total B-6 content using Saccharomyces uvarum, and compared with the vitamin B-6 values of the USDA Nutrient Database for Standard Reference. The vitamin B-6 status of the subjects were assessed utilizing vitamin B-6 dietary intake, erythrocyte alanine aminotransferase (EALAT) activity coefficient, and plasma pyridoxal phosphate (PLP) concentration. The overall vitamin B-6 analyzed values for these foods were significantly lower than the USDA database values. The dietary vitamin B-6 intakes of the subjects based on analyzed values (0.57 ± 0.26 mg/d) were significantly lower (p < 0.0001) than based on USDA database values (0.97 ± 0.31 mg/d). Estimation of vitamin B-6 intakes using analyzed values of the local foods more accurately represented actual intakes of the children than database values. Twenty-nine percent of the subjects (13% of urban and 45% of rural) reported consuming ≤2/3 1998 RDA, for United States and Canada, of vitamin B-6. EALAT activity coefficients ≥1.25 were observed in 30% of the subjects of which 18% were urban and 42% rural. PLP concentrations ≤30 nmol/L were observed in 25% of the subjects (10% of urban and 40% of rural). Significantly more (p < 0.05) rural children than urban had inadequate vitamin B-6 status as assessed by the three indices. Similar percentages of nude and female subjects had inadequate vitamin B-6 status. Vitamin B-6 inadequacy was prevalent among the Indonesian children, especially those in rural areas, participating in this study.
