The purpose of this study was to compare nutrients intake, eating behavior, and health indices according to intake frequency of wheat-based foods, using results from the 2013~2015 National Health and Nutrition Examination Survey. Subjects were 882 men age 40~64. According to intake frequency of wheat-based foods per week, two groups (Low intake group (LG); less than four times, High intake group (HG); more than four times) were divided, and their percentages were 54.0% and 46.0% respectively. Frequency of consuming wheat-based foods per week was 4.80, and there was significant difference (p<0.001) in both groups. Intake frequency according to wheat-based foods was high in noodles, cookies, and breads. Daily energy intake was higher, approximately 630 kcal in HG than LG (p<0.001). Also, energy ratio of fat and protein was higher in HG. There were significant differences in nutrient density per 1,000 kcal of minerals and vitamins between the two groups (p<0.01, p<0.001), except calcium, phosphorus, and niacin. In dietary behavior, frequency of meals (daily) was significant. In total cholesterol and LDL-cholesterol of health indices, HG was higher than LG (p<0.01). Results of this study reveal that frequent intake of wheat-based foods has negative effect on nutrition and health.

The purpose of this study was to obtain baseline data on dietary management of women's constipation. We estimated the prevalence of self reported constipation, bowel habits and foods & nutrients intake. The subjects were 169 female college students (normal = 92, constipation group = 77) aged 19 to 23 years. We conducted anthropometric measurements, an evacuation habits survey, and a dietary intake assessment for three days by a 24 hour recall method. The prevalence of self reported constipation was 46% (n = 77). Results showed that bowel habits (the difficulty of evacuation, the duration of evacuation and the feeling after evacuation) were significantly different between the two groups. Over 65% of constipation group used laxatives for constipation relief. Frequency of stress and deep sleeping were related with constipation. In daily food consumption and nutrients intake, there was not a significant difference between the groups. However in relation to bowel habits which factors influence constipation, the study showed that the intake of water, potatoes, kimchi, and fruits correlated with evacuation facility. Further, there were no findings in the difference of foods consumption and nutrients intake between the two groups. But some life style changes and food intakes (potato and kimchi) may be useful to improve constipation symptoms in young women.

This study was to investigate the relation of nutrients intake, health status, and bone mineral density in middle-aged women. Daily nutrients intake were analyzed by convenient method. The BMD of subjects were measured by Dual Energy X-ray Absorptiometry(DEXA). BMD was measured at the spine(vertebrae L2-L4) and femur(neck, Ward's triangle and trochanter). The nutrients intake of subjects were higher than recommended dietary allowances(RDA) except for calorie, iron, calcium, vitamin B1. Nutrients intake of vitamin A(p<0.05), iron(p<0.01), vitamin $B_2$(p<0.05), niacin(p<0.05), and vitamin C(p<0.05) between $\leq$49 yr group and $\geq$50 yr group. Mean daily intake of calcium was much less than the Korean RDA, 78.5% in $\leq$49 yr group and 77.3% in $\geq$50 yr group. 35.8% of the subjects under 50 years of age($\leq$49 yr group) and 77.4% of the subjects from 50 years up($\geq$50 yr group) were classified as osteopenia or osteoporosis. BMD of L2-L4 were positively correlated with height(p<0.05), weight(p<0.05) and BMI(p<0.05). BMD of femoral neck was positively correlated with BMI(p<0.05), BMD of Ward's triangle was positively correlated with weight(p<0.001). But BMD of L2-L4 and femoral neck were negatively correlated with age(p<0.05), menarche(p<0.05). BMD of Ward's triangle was negatively correlated with age(p<0.001). The BMD of L2-L4 were positively correlated with animal protein(p<0.05), calcium(p<0.05) and iron(p<0.05). The BMD of femoral neck was positively correlated with animal protein(p<0.05). The BMD of Ward's triangle was positively correlated with animal protein(p<0.001) and iron(p<0.001). The above results suggest that it should be difficult to prevent middle-aged women's bone destruction through nutrients intake. Further investigation is necessary to prove the mutual relations between BMD, exercise, and calcium intake. Therefore, middle-aged women will need proper exercise as well as Ca supplementation in order to prevent osteoporosis with aging.

The purpose of this study was to estimate the iron availability and to analyze dietary factors which influence hematological indices of 130 female adolescents with iron deficiency anemia. Intakes of iron and other nutrients were estimated using a self-administrated questionnaire combined with the 24-hour recall mehtod and iron availability was calculated by Monsen's method. Mean daily intakes of calorie, protein and vitamin C were 1631.0kcal(77.7% of RDA), 54.7g(84.2% of RDA) and 45.7mg(83.0% of RDA), respectively. In terms of iron, mean daily intake was 8.7mg(48.3% of RDA) and heme iron intake was 3.0mg which correspond to 34% of total iron intake. The amount of total absorbable iron was 1.5mg and the estimated bioavailability of dietary iron was 17.2%. In summary, intake of several nutrients for most of the subjects were under RDA. Dietary factors affecting hematological indices were analyzed by stepwise multiple regression. Intake of vitamin C was a major determinant of Hb level, while both intake of enhancing factor and iron availability were major determinants of serum ferritin level. In conclusion proper nutritional education and guidance for iron deficiency anemic female adoalescent needs to be developed and to improve their iron storage should be increased intakes of enhancing factors, female adoalescents.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea. The subjects were 64 Chinese college students in Korea (educated group, 32 students vs. non-educated group, 32 students). Educated group was lessoned as group and/or individual. Nutrition education program consisted of four lessons (40min/lesson), '6 major nutrients & function (group lesson)', '6 food group and sources (group lesson)', 'personalized daily needed energy and food exchange units using Food Exchange System (individual lesson)', and 'smart choice of snacks and eating-out foods (group lesson)'. We examined the differences between educated group and non-educated group in nutrition knowledge, dietary attitudes and nutrients intake. After education, there were positive improvements on nutrition knowledge: 'function and foods of 6 nutrients', on dietary attitudes: 'type of breakfast' in educated group. In the evaluation of nutrient intakes according to Dietary Reference Intakes for Korean (KDRI), there were positive improvements on intake levels of riboflavin, fiber, vitamin B6, vitamin C, folate, Ca and K in the educated group. In the index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased in the educated group. In conclusion, it is possible to improve nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea through the nutrition education focused on personalized daily needed energy and food exchange units.

The purpose of this study was to investigate the effects of preschool children's taste preferences on their intake of nutrients and the degree of dental caries. The subjects were 126 preschool children (boys 62 and girls 64) in Daegu area. Their taste preferences and food intake were investigated and their teeth were also examined. The energy intake of boys (1550 kcal) were significantly higher than that of girls (1441 kcal). Daily dietary intakes of nutrients-except niacin and vitamin C-were higher than those of RDA. Vitamin B$_1$ intake of the group preferring a salty taste was significantly lower than that of the other group (p<0.05). Vitamin B$_2$ intake of the group preferring a salty taste was significantly higher than that of the other group (p<0.05). Vitamin C intake of the group preferring a hot taste was significantly higher than that of the other group (p<0.05). The group with a preference for sweet had more experiences of dental caries and more decayed teeth than the other group, but which is not significant. The experiences of dental caries were negatively correlated with protein intake (p<0.01). The decayed teeth were negatively correlated with energy and protein intakes (p<0.01). Our data suggested that taste preferences are associated with vitamins intake and the degree of dental caries in preschool children. It means the sweet preference increased the experiences of the dental caries.

The purpose of this study was to investigate the relationships of dietary nutrients and serum heavy metals in college women living Choong-Nam area of Korea. The mean age, height, weight, and BMI were 22.9years, 158.74cm, 53.39kg, and 21.71kg/$m^2$ respectively. The mean daily energy intake was 85.9% of RDA for Koreans. The ratio of energy from carbohydrate, fat, and protein was 61:23:16. And the daily vitamin A, B$_2$, Ca were 90%, 78%, 60% of RDA for Korea, respectively. The mean serum levels of Pb, Cd, Cr were 0.190, 0.005, 0.025$\mu\textrm{g}$/$m\ell$, respectively. The serum Cd was significantly different with dietary carbohydrate(p＜0.05). And the serum Cr was significantly different with dietary protein intake(p＜0.05), phosphorus(p＜0.01), potassium(p＜0.05). respectively.

This study was performed to investigate the adequacy of dietary fat and protein intakes among female college students. Daily intakes of energy, fat, protein, major amino acids and other nutrients were measured in 52 female college students. Daily energy intake was 75.8% of the recommended intake. Fat and protein consist 19.2% and 16.7% of the total calorie, respectively. The average protein consumption per day was 105% of the recommended intake. Essential amino acids intakes were more than the recommended amounts which appears in the 6th edition of Recommended Dietary Allowances for Koreans. However, when the intake of each essential amino acid was compared to the recommended amino acid requirement pattern, these subjects did not meet the estimated requirements. There was a highly significant correlation between daily protein intake and lipid intake implying the major sources of protein in the diet were also major sources of fat. Daily intakes of dietary fiber, vitamin C, iron, and phosphorous were above the recommended levels of intake. However, blood hemoglobin concentration was marginal indicating dietary iron consumption is not a good marker for iron status. Also, calcium intake was only 63.5% of the recommended intake. Therefore, these results imply that main problems for these subjects are low energy consumption, low calcium intake, and the quality of protein. However, as opposed to the hypothesis, the main energy sources were not the food items high in saturated fats such as instant foods, which should be emphasized further.

In order to investigate the effects of frequent eating-out and breakfast skipping of working men on body mass index and nutrients intake status, working male adults aged 20 or over were selected (n = 1883) from the data of 2001 Korea national health and nutrition survey. The subjects were divided into 4 groups according to the eating-out frequency(high: once or more daily, low: less than once daily) and breakfast eating or not. Four groups were high eating-out with breakfast eating (n = 609), high eating-out with breakfast skipping (n = 192), low eating-out with breakfast eating (n = 877), and low eating-out with breakfast skipping (n = 205). High eating-out group showed higher body mass index (BMI) than low eating-out group, but the difference of BMI was disappeared when adjusted with age, residence region and family income. However high eating-out group in case of breakfast eating, compared with the low eating-out, showed higher intakes or densities of energy, fat, fat-energy% and higher ratio of energy-fat overintake, and also showed higher mean nutritional adequacy ratio and lower ratio of nutrients intake deficiency. Calcium, iron, vitamin A and C intakes were not affected by eating-out frequency, but were lowered by breakfast skipping. Breakfast skipping also decreased intake frequency of unprocessed cereals and increased those of ramyon and carbonated and alcoholic beverages. From the results frequent eating-out with breakfast eating caused increased intakes of energy and fat, but did not cause BMI increase. Breakfast skipping, but not eating-out, had negative influences on mineral and vitamin intakes. Accordingly good eating-out as well as breakfast eating should be exceedingly emphasized at nutrition education for the working males.

This study was carried out to compare the nutrients intakes, factors to influence on nutrient intake and frequency of food group intake between the two gruops of elderly living in Yangcheon, Seoul(n=105) and in Yongin(n=159). The results obtained by cross-sectional survey using questionnaires were as follows. 1) The average age of the subjects was 71.9 and there was no significant difference in age and gender distribution according to the residential areas. 2) The intakes of energy, protein, Fe, vitamin A, niacin, thiamin, riboflavin, and vitamin C were significantly higher in the urban elderly than those of the rural elderly(p<0.05).3) The average daily intakes of energy, protein, Ca and Fe of the subjects were lower than those of the Korean RDAs in general and the rural elderly showed more severe deficiencies. 4) Individual nutrient intakes and food group intakes were related to the pocket money, number of different foods taken daily, education level, residential area, and the degree of exercise. These results suggested the needs of nutrition intervention for the low-income, rural elderly.
