To assess trans fatty acids (tFAs) intake of middle school students in Busan, behavior of having meals and 3 day's food record were surveyed in 800 subjects. 35.3% of subjects responded to twice a day in frequency of snack intake. Preferred snack items were ice cream (68.6%) and milk (57.0%). Subjects of dining out preferred jajangmyon (54.6%), seasoned chicken (50.5%), fried chicken (35-3%) in order when dined out. Mean daily tFAs intake of subjects was 1.68$\pm$0.04 g. Mean daily intake level of girls was 1.89$\pm$0.06 g which was significantly higher than that of boys, 1.40 $\pm$ 0.05 g (p<0.001). Naturally derived tFAs intake was 1.04$\pm$0.03 g which corresponded to 62.1% of total tFAs intake per day and industrially derived tFAs intake was 0.64 $\pm$ 0.02 g, 37.9% of total tFAs intake per day. Calorie percentage of tFAs was 0.8% and fat percentage of tFAs was 3.16%. The level of tFAs intake showed a significant difference with monthly allowance (p<0.05) and frequency of snack intake (p<0.001) in girls, which was not the case in boys. The main sources of tFAs were milk and dairy products (34.3%), bakeries (18.3%), and fish and meat products (16.2%), in order. From above results, we can conclude that tFAs intake of middle school student is not as much as that of Western teenagers. However, exact estimation of tFAs intake requires database of tFAs in broad range of processed foods commonly consumed in Korea.
