This study aims at examining perception, life style and food habits by residence type in female college students. The data analysis were conducted by a body fat analyzer and questionnaire survey. The subjects were 230 female college students divided into three groups: home-living group, dormitory group, and self-boarding group. The age of the subjects was 20.3~21.7 years old. Among the subjects, 46.1% were home-living group, 27.4% dormitory group, and 26.5% self-boarding group. There was no significant satisfaction of body weight by residence type. Their exercise frequency were not significant by the groups. The exercise time per day was much in home-living group than dormitory group, and self-boarding group(p<0.05). The meal eating time was regular in dormitory group than in home-living group and self-boarding group at p<0.05. 'Frequency of much food intake', 'frequency of restaurant meal', and 'saltness' were significant by the groups at p<0.05 respectively. Breakfast frequency was significant different by the groups at p<0.05. Intakes frequency of cereals in breakfast, meats in breakfast, vegetables in breakfast was different by the groups at p<0.05.

This study was carried out to examine dietary habits, food frequency and dietary attitudes by gender and nutrition knowledge level in upper-grade school children. Subjects were 223 boys and 208 girls attending 13 elementary schools (5 th and 6 th graders). A self-administered questionnaire was developed to assess nutrition knowledge, dietary habits, food frequency, and dietary attitudes. Nutrition knowledge score assessed by 19 questions was significantly higher in girls than in boys. There were significant differences between boys and girls in several items in dietary habits such as enough breakfast time, dinner regularity, number of side dishes, eating speed, type of snack after dinner, and degree of saltiness of dishes. Girls consumed staple foods such as rice, noodles or bread more frequently, and consumed less frequently ramyun, fried foods, fast foods, and Chinese foods than boys. In addition, girls had more positive dietary attitudes in trying to reduce fast foods, Chinese foods, ramyun and fried foods. Also children in the high or moderate nutrition knowledge level groups had better dietary habits in frequency of meals, frequency of breakfast, enough breakfast time, dinner regularity, activity during the meal, number of side dishes, eating speed, type of snack after dinner, and better food choices by eating staple foods and vegetable side dishes, meats and beans more frequently, and fried foods, doughnuts/cakes, Chinese foods less frequently, and had better dietary attitudes in breakfast, vegetables and fruit intake than children in the low nutrition knowledge level group. Our results showed that dietary habits, food frequency and dietary attitudes were different by gender and nutrition knowledge level. These results suggest that in developing nutrition education program for elementary school children, the differences between gender and nutrition knowledge level should be considered. Nutrition education in elementary schools may change dietary habits and dietary attitudes through increasing nutrition knowledge.

The purpose of this study was to find out the prevalence of constipation nutrition knowledge on dietary fiber and frequency of dietary fiber foods intake of 3rd grade high school girls in Kangnung and Seoul. The total 412 questionnaires were analyzed. Defecation frequency was irregular in 47.6% of the students 21.6% had less than twice a week. Those who were in a hurry during defecation frequency was irregular in 47.6% of the students 21.6% had less than twice a week. Those who were in a hurry during defecation were 57.9% and those spent more than 10 min. for defecation were 21.8% More than half of the students(56.6%) answered to have constipation and 13.8% had taken laxative pills more than once during the last one month period. The nutrition knowledge score was relatively high 7.63 points out of possible 10. Dietary fiber intake scores measured by food frequency questionnaire were 3.78 for fruits 3.71 points out of possible 10. Dietary fiber food intake scores measured by food frequency questionnaire were 3.78 for fruits 3.71 for vegetables and 3.37 for seaweeds meaning taken once a week to 2-3 times per month. For the diagnosis of defecation difficulty a factor called "constipation index" was introduced which was composed of defecation frequency time spending for defecation easiness in defecation and feeling of residue in the intestine after defecation. The Cronbach a coefficient of constipation index was 71. Constipation index was significantly correlated with stress level(p<0.05) haste during defecation(p<.01) and defecation time(p<.01) The higher the stress level the more hurry during defecation and the later the defecation the higher the constipation index. The students who ate more often vegetables and seaweeds had lower constipation index(p<.05, p<.01)05, p<.01)

There is growing evidence that soy isoflavone play beneficial roles in the prevention of chronic diseases such as hormone dependent cancers, cardiovascular diseases, osteoporosis and also reduced incidence of menopausal symptoms. However current data are not sufficient to determine the effective doses for beneficial as well as harmful effects and to support dietary recommendation for isoflavones. Since soy products containing isoflavone are one of the common food items that Koreans consume daily basis, assessing consumption of soy isoflavone by Koreans will give a valuable information on making dietary recommendations for isoflavones. the present study was designed to assess dietary intake of isoflavone of Korean middle-aged women who might receive the most beneficial effects from isoflavone consumption thereby prevent post menopausal related symptoms and diseases. In this study isoflavone contents of soy products were analyzed and soy products and isoflavone consumption of these subjects were assessed by a self-reported dietary questionnaire and isoflavone intake data base. Subjects were consisted of 178 Korean women (35~60 y) who live in urban and rural area. All subjects provided detailed information on demographics, anthropometry, health history, menopausal symptoms, health history, menopausal symptoms, and dietary intake using food frequency questionnaire (FFQ) which was developed for Koreans. The average age of the subjects was 46.6 years. The soy products which the subjects frequently consumed were soybean paste soup, braised fried soybean, tofu residue stew, tofu, soy milk, natto stew, bean sprouts, and soybean broth which contained 10.68 mg, 3.34 mg, 2.44 mg, 2.42 mg, 2.42 mg, 1.12 mg, 1.02 mg, 0.33 mg of isoflavone per 100 g, respectively. The estimated daily intake (EDI) of isoflavones ranged from 0 to 144.3 mg, and the mean daily isoflavone (sum of daidzein and genisten) intake of the subjects was 24.41 mg.

The objective of this study was to investigate the consumption pattern of snacks-containing trans-fatty acid in adolescents living in the Kwang-ju area of Korea, and to analyze the relevance toward their eating behaviors, body composition, nutrient intakes, and consumption frequency of snacks-containing trans fatty acid. A survey questionnaire was developed in order to investigate general environmental factors, eating behavior, nutritional knowledge, and the consumption frequency of snacks-containing trans fatty acid. A total of 312 middle school students were surveyed. The collection rate was 97% and ultimately 282 cases were analyzed. Anthropometric measurements, body composition data, and nutrient intakes were also collected. The consumption frequencies for snacks-containing trans-fatty acid were negatively correlated with food behavior scores (p<0.01) however, pocket money and snack intake frequency per day were positively correlated with consumption frequency. Also, snack consumption frequency had some correlation with the subjects' anthropometric measurements and body composition data such as total body water (p<0.01), body protein (p<0.01), body minerals (p<0.01), and skeletal muscle mass (p<0.01). Finally, the consumption frequency of snacks-containing trans fatty acid was significantly correlated with calcium intake (p<0.05), it also showed correlations with vitamin A, retinol, ${\beta}-carotene$, and folic acid intake, although statistical significance was not verified.

Nutrient intakes estimated using a 24-hr recall, a dirt record and a food frequency questionnaire(FFQ) were compared in a group of ninety-four elderly people(21 males, 73 females) in Cheongju, a city in Chung-Buk province. Mean intakes for energy, protein, Ca, p, Na, K thiamin and niacin obtained from the diet record were higher than those from the 24-hr recall. Mean intakes for energy, protein, Ca, P, Na, K thiamin, niacin and vitamin C from the FFQ were higher than those obtained from the 24-hr recall or the diet record. Correlation coefficients between the nutrient intake values from the 24-hr recall and those from the diet record ranged from 0.84 to 0.95 and were significantly correlated(p < 0.001). About 80% of the subjects in the lowest quintile by the 24-hr recall were also in the lowest two quintiles by the diet record. While the percentage fallen into the opposite category ranged from 0% to 15%. For most nutrients, at least 65% of the subjects when classified by the 24-hr recall fell into the same quintile when classified by the diet record, and the mean kappa value was 0.7. About 52% of the subjects in the lowest category by the 24-hr recall fell into the lowest two categories by FFQ. The mean percentage of the subjects in the lowest quintile by the diet record or in the lowest two quintiles by the FFQ was 51%. For most nutrients, at least 24% of each of the subjects when classified by both the 24-hr recall and the diet record fell into the same category when classified by the FFQ. The kappa values between the 24-hr recall or the diet recall and the FFQ were 0.17. These data indicate that in elderly subjects the 24-hr recall can provide very similar information to that obtained from the diet record but the FFQ can not provide good information if the right FFQ method is not used for only elderly subjects.

Objectives: The objective of this study was to verify the validity of a mobile phone application (app) that applies a 24-hour dietary recall with meal photos, as a means of being a more accurate method of estimating dietary sodium intake. Methods: Of the 203 subjects enrolled, 172 subjects (84 males and 88 females) were selected for the final analysis, excluding those with an intake less than 500 kcal and urine output less than 500 ml. Dietary sodium assessment methods used for comparing with the 24-hour urinary sodium excretion are as follows: 1) face-to-face 24-hour dietary recall, 2) 24-hour dietary recall using the mobile app, 3) face-to-face 24-hour dietary recall considering liquid intakes from soup, stew, water kimchi and noodle, etc (liquid-based dishes), 4) 24-hour dietary recall using the mobile app considering liquid intakes from liquid-based dishes, and 5) food frequency questionnaire. Repeated ANOVA with Bonferroni method was used for comparing the average sodium intake, and Pearson's correlation was applied to correlate the methods used. Results: In women, no significant difference was observed in the average sodium intake between all methods. Moreover, analysis in men and total adults revealed no significant difference between the 24-hour urinary sodium secretion, and 24-hour dietary recall using the app and 24-hour dietary recall using the app considering liquid intakes. Sodium intake by food frequency questionnaire was significantly different when compared with the intake determined from 24-hour urinary sodium excretion. Sodium intake from all methods (except food frequency questionnaire) significantly correlated with values obtained from 24-hour urine sodium excretion. Conclusions: Results of this study validated a mobile phone app using a 24-hour dietary recall with meal photos to better estimate dietary sodium intakes. It is believed that further studies in the future will enable the application as a tool to more accurately determine sodium intake.
