    Abstract:
    OBJECTIVE: To study the nutritional status and differences in vitamin B1, vitamin B2, and niacin of the urban/rural infants in Shandong Province, and to provide scientific basis for infants nutrition interventions. METHODS: 106 urban infants and 290 rural infants were selected from a city in Shandong Province. Forty milliliter urinary was collected from each one, which was adjusted to pH 4-5 with concentrated hydrochloric acid immediately. The concentration of thiamine, riboflavin and niacin in the urine was detected by fluorescence method. RESULTS: The insufficient percentages of vitamin B, vitamin B2 and niacin in urban infants were 1.9%, 8.0% and 9.1%, and that in rural infants were 4.5%, 56.7% and 27.1%. The median concentrations of vitamin B1 in urban and rural infants were 495.00 and 420.56 microg/g respectively, in which the 12-month and 24-month groups in urban were higher than that in rural (P<0.05). The medians of vitamin B2 content in urban and rural infants were 303.07 and 70.88 microg/g, and the content of vitamin B2 in urban infants was higher than that in rural infants in each group (P<0.05). The median concentrations of niacin content in urban and rural infants were 6.31 and 4.22 microg/g, and the niacin content of 6month-, 12 month-, 18 month- and 24 month- groups in urban infants were higher than that in rural infants (P<0.05). CONCLUSION: There were significant differences in vitamin B1, B2 and niacin content of infants between urban and rural areas, and the nutriture of urban infants was better than the rural infants. More improvement measures should be given to infants in rural areas for the high proportion of vitamin B, and niacin deficiency.
