Abstract:
residing in Seoul using the 3-day food record. Frequency for breakfast skipping was the highest as compared with lunch and dinner skipping. Frequencies for breakfast and lunch skipping were significantly higher in weekend than weekday (p < 0.05). The daily average food, vegetable food and animal food intakes were 1,327.6 g, 800.5 g, and 425.8 g, respectively. Total food and vegetable food intakes of weekday were significantly higher than weekend (p < 0.05). The dietary variety score (DVS) was 20.5 in daily average, 23.3 in weekday and 15.1 in weekend, which showed significantly higher in weekday than weekend (p < 0.05). The daily averages of energy, protein, fat and carbohydrate intake were 2244.9 kcal, 89 g, 72.6 g, and 311.2 g, respectively. Fat intake was significantly lower and carbohydrate, fiber, phosphate, iron, sodium, potassium, vitamin A, niacin, folate, and vitamin C intakes were significantly higher in weekday than weekend (p < 0.05). The percentages of energy intake from carbohydrate, protein, and fat were 55.4%, 15.8%, 28.8% in daily average, 56.8%, 15.8%, 27.4% in weekday and 53.6%, 15.8%, 30.7% in weekend, respectively. The percentages of energy intake from carbohydrate in weekday and weekend were below 60%, and that from fat was above 27% in weekday and weekend. Carbohydrate intake was significantly higher and fat intake was significantly lower in weekday than weekend (p < 0.05). Energy intakes of daily average, weekday and weekend were above 83% as compared with estimated energy requirement (EER). Intakes of dietary fiber, calcium, potassium, vitamin C, riboflavin and folate were below 75% as compared with adequate intake (AI) or recommended intake (RI). Mean adequacy ratios (MAR), an index of overall dietary quality were 0.78 in daily average, 0.80 in weekday and 0.75 in weekend. MAR of weekend showed significantly lower than weekday (p < 0.05). This study revealed that the overall nutrient intake status was worse in weekend than weekday among high school boys.
