Riboflavin Nutritional Status of Preschool Children in Busan Assessed by Dietary Intake and Urinary Excretion

To assess riboflavin status by dietary intake and urinary excretion of preschool children in Busan and to evaluate the relationship of intakes of food and nutrient with urinary riboflavin excretion, riboflavin food frequencies of 40 common foods affecting intakes of riboflavin by food fequency method, nutrient intake by 24hr recall and 24hr urinary riboflavin excretion were measured with 97 preschool children. The mean riboflavin intake was 0.90 mg and above RDA. Dairy group was the primary source of riboflavin intake and provided 44.8% of the total daily riboflavin intake. The mean urinary riboflavin excretion and riboflavin excretion per gram of creatinine were 395.21$\mu\textrm{g}$ and 2110.41$\mu\textrm{g}$ respectively, The mean riboflavin intake (p<0.01, p<0.01), riboflavin density (p <0.001, p<0.001) and urinary riboflavin excretion per gram of creatinine (p<0.05, p<0.05) were significantly low with the two patterns of food group intake where dairy group was omitted (GMVFDS = 111101, consuming no dairy group and GMVFDS=l11001, consuming no fruit and dairy groups). On the basis of urinary riboflavin excretion per gram of creatinine, 14.3% of subjects in the group aged 1 to 3 and 18.2% of subjects in the group aged 4 to 6 were at risk of deficiency respectively. The urinary riboflavin excretion per gram of creatinine showed positive significant correlations with usual intakes of riboflavin from food groups of dairy (p<0.05), meat (p<0.05) and animal (p<0.05). So nutritional education is needed in order to consume dairy food group daily and to increase usual intake of animal food group including meat.(Korean J Nutrition 35(9) : 970~981, 2002)
