  • 24-hour recall is the dietary assessment method most frequently used to evaluate dietary intake; however, accuracy is an issue when using this method, especially in large-scale studies. The purpose of this study was to assess the validity of dietary intake estimation using one serving size. Estimates of energy and nutrients taken in over a 24-hr period based on actual intake amount (24HRAI) and based on estimates of one serving size (24HRSS) were compared. Data were analyzed using a paired t-test, Pearson's correlation coefficients, and a cross-classification method. In male subjects, intake levels of energy, fat, vitamin C, vitamin $B_1$, Zn, and total food measured using 24HRAI were significantly higher than those measured using 24HRSS. In female subjects, intake of carbohydrates, fiber, fat, vitamin A, vitamin C, vitamin B complexes, various minerals, and total food measured using 24HRAI were significantly lower than those measured using 24HRSS. Energy-adjusted Pearson's correlation coefficients revealed that intake of all nutrients showed a significant positive relationship between the two measurement methods in both males and females. Cross-classification analysis revealed that 50.5~67.6% of women and 40.3~71% of men were classified in the same quartile of intake of each nutrient when comparing data from 24HRAI and 24HRSS. We conclude that using one serving size in 24-hr recall analysis was valid and therefore may be used in studies to assess food consumption in the general adult population. Also, this method can be used to classify energy and nutrient intake into quartile, which is useful in examining the association between diet and chronic diseases.

  • To assess the food habits, nutrient intake and diet quality of preschool children aged 1 to 6 in Pusan by their meals and snacks, dietary survey was conducted with 176 subjects by a questionnaire and 24hr recall method. 63.1% of the subjects often skipped meals and 72.1% of those skipped breakfast in the main. 94.5% had snacks over once per day. The mean energy intake was 1406.4kcal, with 57.7% of energy intake being supplied by carbohydrate, 13.7% by protein, 28.6% by fat. 54.9%, 71.7% and 26.5% of intakes of protein, calcium and iron were supplied respectively by animal food. Most of iron intake came from plant origin. The percent of calcium intake from animal origin was low significantly in a group aged 4 to 6(p<0.05). The mean intakes of calcium, iron and niacin of total subjects were below Recommended Dietary Allo wance(RDA) for Koreans. The mean intakes of iron and niacin of a group aged 1 to 3 were below RDA as well as those of energy, caicium, vitamin B2 and niacin of the group aged 4 to 6. For calcium, iron, vitamin A, niacin and vitamin C, proportions of subjects with intake levels less than 75% of RDA were all over 36%. For most nutrients, proportions of subjects with intake levels less than 75% of RDA were higher in the group aged 4 to 6 than in the group aged 1 to 3. Nutrient adequacy ratios(NAR) were the lowest in iron in case of the group aged 1 to 3 and in calcium in case of the group aged 4 to 6. NAR of iron increased and that of vitamin B2 decreased significantly along increase age(p<0.05). The mean adequacy ratios(MAR) were 0.82 for total subjects, 0.83 for the group aged 1 to 3 and 0.80 for the group aged 4 to 6. The indexes of nutritional quality(INQ) of calcium, iron and niacin of the group aged 1 to 3 were below 1 as well as those of calcium, vitamin B2 and niacin of the group aged 4 to 6. Both of the age groups received 31.6~59.0% of daily intakes of energy, fat, calcium, phosphrous, vitamin B2 and vitamin C from snacks. So snacks clearly play an important role in dietary intake. Both of the NARs of most nutrients and MAR were higher in snacks than in three meals. The INQs of calcium and iron from three meals and those of iron, vitamin A, vitamin B1 and niacin from snacks of the group aged 1 to 3 were all below 1. The INQs of calcium and vitamin B2 from three meals and those of vitamin A and niacin from snacks of the group aged 4 to 6 were all below 1. In conclusion, nutritional characteristics were different between the two age groups. More attention should be paid to improve adequacy of nutrient intake through meals. And dietary management for snacks is needed especially in the group aged 1 to 3.

  • The purpose of this study was to evaluate nutritional value of traditional fermented foods by dietary intake of university students living in Chungnam. 210 students were asked for their daily food intake using 24-hour recall method for 3 days. And daily nutrient intakes from total foods and fermented foods were analyzed and compared. The mean weight, height, and BMI of the subjects were 67.36㎏, 174.39㎝, 22.15㎏/$m^2$ in men and 53.45㎏, 161.86㎝, 20.40㎏/$m^2$ in women, respectively. The daily intakes of protein, phosphorus, and vitamin B1 were 106.82%, 137.88%, and 108.99% of the Korean RDA. However, the energy, calcium, iron, vitamin A, vitamin B2, niacin, vitamin C intakes did not reached the RDA for Koreans. The fermented food intake was 9.09% of total food intake. And the percentages of fermented food intakes were 81.53% for Kimchi and 14.75% for Chang. The vegetable protein, vegetable oil, dietary fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B1, vitamin B2, niacin and vitamin C intakes per 1000㎉ consumption from fermented foods were significantly higher than those from total foods. The fermented food intake showed positive correlation with iron, and plant iron intakes. In conclusion, the percentage of fermented food intake was about 9% and the major items were Kimchi and alcoholi beverages in university students. Fermented food intake may be important to improve the intakes of calcium, iron and vitamin.

  • This study was conducted to assess dietary intake and quality obtained by 24-hour recall method between Korean-Chinese in Yanbian, China(Korean-Chinese) and Koreans in Kuri, Korea(Koreans). The subjects consisted of 730 Korean-Chinese and 696 Koreans. Mean daily energy intake of Korean-Chinese was 1,788kcal and that of Korean was 1,844kcal. Proportions of energy intake from carbohydrate, fat, and protein were 62.6: 16.9: 14.2 for Korean-Chinese and 65.4: 16.3: 14.4 for Koreans. Nutrient intake levels of Koreans were higher than those of Korean-chinese in most nutrients. Calcium and vitamin $B_2$ intakes as percent of Korean RDA were less than 60% in Korean-Chinese. Koreans consumed calcium and vitamin A in the level less than 80% of Korean RDA. Iron intake level of Korean females was less than 75% of Korean RDA. Korean-Chinese consumed 90.4% of food from plant origin, and Koreans consumed 82.5% of food from plant origin. Mean dietary diversity score(DDS) of Korean-Chinese, $3.00{\pm}0.39$, was significantly lower than that of Koreans, $3.73{\pm}0.76(p<0.05)$. Mean dietary variety score(DVS) of Korean-Chinese, 13.6, was significantly lower than that of Koreans, 20.1(p<0.001). According to these results, some adults in the both Korean-Chinese and Koreans did not consume enough nutrients, especially calcium and vitamin $B_2$ intake for Korean-Chinese and calcium and vitamin A intake for Koreans. Dietary qualities of Korean-Chinese subjects and Korean females were not adequate. In the future, further research to promote dietary quality of Koreans including Korean-Chinese must consider the results of this study.

  • This study was conducted to identify dietary factors that may affect the occurrence of gastric cancer in Koreans. Preoperative daily nutrition intake and diet quality of patients diagnosed with gastric cancer were evaluated. Collected data were comparatively analyzed by gender. The results were then used to prepare basic materials to aid in the creation of a desirable postoperative nutrition management program. The subjects of this study were 812 patients (562 men and 250 women) who were diagnosed with gastric cancer and admitted for surgery at Soonchunhyang University Hospital between January 2003 and December 2010. Nutrition intake and diet quality were evaluated by the 24-hr recall method, the nutrient adequacy ratio, mean adequacy ratio (MAR), nutrient density (ND), index of nutritional quality (INQ), dietary variety score (DVS), and dietary diversity score (DDS). The rate of skipping meals and eating fast, alcohol consumption, and smoking were significantly higher in males than those in females. The levels of energy, protein, fat, carbohydrate, phosphorous, sodium, potassium, vitamin $B_1$, vitamin $B_2$, niacin, and cholesterol consumption were significantly higher in males than those in females. Intake of fiber, zinc, vitamin A, retinol, carotene, folic acid were significantly higher in females than those in males. MAR in males was significantly higher (0.83) than that in females (0.79). INQ values were higher in females for zinc, vitamin A, vitamin $B_2$, vitamin $B_6$, and folic acid than those in males. The average DVS was 17.63 for females and 13.19 for males. The average DDS was 3.68 and the male's average score was 3.44, whereas the female's average score was 3.92. In conclusion, males had more dietary habit problems and poor nutritional balance than those of females. Our findings suggest that proper nutritional management and adequate dietary education for the primary prevention of gastric cancer should be emphasized in men.

  • The vitamin $B_{6}$ status of 49 healthy college student (women, aged 20-26 y) was estimated for evaluation of vitamin $B_{6}$ status and the Korean Recommended Dietary Allowance (RDA) for vitamin $B_{6}$. The average daily vitamin $B_{6}$ intake of the subjects was 0.86 $\pm$ 0.289 mg/d or 61.43 $\pm$ 24.10% of Korean RDA. The average ratio of vitamin $B_{6}$ intake to daily protein intake was 0.014 $\pm$ 0.003 mg/g protein. Foods from animal and plaint sources provided 34.25 $\pm$ 18.62% and 65.78 $\pm$ 18.72%, respectively, of total vitamin $B_{6}$. Plasma pyridoxal 5'-phosphate (PLP) concentration was significantly (p<.01 - p<.001) positively correlated to intakes of all other nutrients except vitamin C. However, no significant correlation was found between plasma PLP and nutrient intake. Vitamin $B_{6}$ intake only tended to have a positive correlation with plasma PLP concentration. Plasma total cholesterol was correlated to plasma PLP concentration (p<.05). Plasma PLP had no correlation with levels of glucose, triglyceride, and albumin. These results confirm that the present Korea RDA for vitamin $B_{6}$ of 1.4mg/d based on 0.02 mg/g protein is adequate.

  • This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.

  • Because the intake of vitamin A had been consistently found to be low among Koreans, there has been a concern that mild vitamin A deficiency might be prevalent in the population. However, the inaccuracy of vitamin A database has long been suspected database for the nutrient. This study was performed to assess the vitamin A and E status in 208 adults over 20 years of age living in a rural area of Korea. Newly modified database for vitamin A and E was used to estimate the dietary intake of the subjects in this study. A cross sectional survey of dietary intake with 24-hour recall method was conducted. Serum retinol and $\alpha$-tocopherol levels of the subjects were analyzed in fasting samples using HPLC. For vitamin A, mean levels of dietary intake and percent of RDA were 620.3$\pm$1087RE/day and 88.6$\pm$155.4%, respectively, which were considerably higher than the levels reported in 1995 Korean national Nutrition survey(470.1RE/day and 67.2%, respectively). For vitamin E, the levels were 9.74$\pm$6.30mg/day and 97.4$\pm$63.0%, respectively. Mean concentration of serum retinol was 83.1$\pm$30.1$\mu\textrm{g}$/dl and none of the subjects was below 10$\mu\textrm{g}$/dl, or deficient level. Mean serum retinol in men, 99.8$\pm$30.4$\mu$g/dl, was significantly higher than in women, 70.7$\pm$23.4$\mu\textrm{g}$/dl (p<0.01). Mean concentration of serum $\alpha$-tocopherol was 1.17$\pm$0.52mg/dl and that of one subject was below 0.5mg/dl, or deficient level. Serum $\alpha$-tocopherol levels of the old subjects were higher than the younger subjects in both sexes(p<0.05). These data suggest that contrary to the previous reports about low intake of vitamin a, intake and serum levels of vitamin A among the subjects are not low. Also, in this study, intake and serum levels of vitamin E are not low, either. (Korean J Nutrition 34(2) : 213~221, 2001)

  • This study has investigated the effect of dietary attitudes on nutritional status of nurses living in Kyungnam province. A total of 249 muses working at hospitals in the Kyungnam area participated in this study. The general characteristics and dietary attitudes of the subjects were surveyed using a self-administered questionnaire, and nutrient intakes were examined using one day 24-hour recall method from November 14 to December 20, in 2001. The data of nutrient intakes were analyzed by the Computer Aided Nutritional Analysis Program and then the diet quality was estimated using the Index of Nutritional Quality (INQ). The subjects were classified as the high score group (17.3 %), medium score group (54.2%), and low score group (28.5%) based on dietary attitude score. The results were as follows: Average age of subjects was 27.1 years old, average nursingexperience was 5.7 years, and 70.7% of the subjects graduated from a junior college. The rate of shift work (45.4%) and non-shift work (54.6%) were similar. The average score on dietary attitudes in thehigh score group was 78.8, and those in he medium score group and in the low score group were 58.6 and 40.8 out of 100 points respectively. The average intake of energy (p < 0.001), carbohydrate (p < 0.001), protein (p < 0.05), animal protein (p < 0.01), animal fat (p < 0.05), vitamin $B_1$ (p < 0.01), vitamin $B_2$ (p < 0.0l), niacin (p < 0.001), Ca (p < 0.001), Fe (p < 0.001), animal Fe (p < 0.01), P (p < 0.001), and crude fiber (p < 0.00l), were significantly higher in the high score group than those in the medium score group and low score group. In the high score group, the average intake of protein, vitamin $B_1$, niacin, vitamin C and P were above 125% of the Korean RDA, and in medium score group, those of vitamin C and P, and in low score group, that of vitamin C were above 125% of the Korean RDA. In the high score group, nutrient of intake below 75% of the Korean RDA was Ca, and those in medium score group were vitamin $B_2$, Ca, and Fe, and those in low score group were energy, vitamin $B_2$, Ca and Fe. The intake ratio of Ca and P showed an unbalanceof 1:2, and that of animal protein/plant protein, and that of animal fat/plant fat were high (1.45-1.64) in all group;. The dietary attitude had a positive correlation (p < 0.00l) with nutrition intake except vitamin A and vitamin C.

  • This study was conducted to investigate the validity of using a cameraphone for a dietary intake survey method. The subjects were 28 female college students. After eating a standard lunch meal which consisted of plain rice, seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi, the quantity of dietary intake, calorie intake & nutrients intake were analyzed by weighed method, diet record method and cameraphone method by dietitian with k without cameraphone analysis training. There were no significant differences in the quantity of 6 foods intake between weighted method and cameraphone method by dietitians with camera phone analysis training. However, the quantity of seaweed soup, bulgogi & cucumber salad intake analyzed by diet record method was significantly lower than the weighed method. And the quantity of seaweed soup, bulgogi, cucumber salad, roasted anchovy and kimchi intake analyzed by the cameraphone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. There were no significant differences in the calorie intake and nutrients intake between the weighted method and camera phone method by dietitians with camera-phone analysis training. However, protein, calcium, iron, phosphorous, Vitamin A, Vitamin $B_2$, Vitamin E and cholesterol intake analyzed by diet record method was significantly lower than the weighed method. And fat and Vitamin $B_2$ intake analyzed by the camera phone method by dietitians without cameraphone analysis training was significantly lower than the weighed method. Therefore, this study suggests that the use of the camerephone may be a valid and convenient method fur evaluating a dietary intake survey. However, systematic and standard education is necessary about the size and volume of dishes and angle of photo for more accurate results.
