This study was conducted to investigate variables related to dietary fiber intake among sixth grade children in an elementary school in Daejon city. One hundred and forty-seven children completed a questionnaire for determining their socioeconomic background and their food habits. Anthropometric measurements were taken, and a 24-hour diet recall method was used to collect three-day food intakes. The socioeconomic status of the children's families belonged to the upper middle class; 53.0% of their fathers and 25.8% of their mothers had completed college or higher degrees. 27.9% of the mothers had jobs, including part-time jobs. Approximately 30% of the children skipped breakfast, 66.4% of the children preferred animal foods to plant foods, and 52.4% of the children preferred green vegetables to yellow or pale vegetables. Grilled meat dishes, such as Grilled beef rib with seasoning, Bulgogi, grilled pork belly and beef steaks, were the most popular types of food eaten outside home by the children. Daily dietary fiber intake was 14.5 g in boys and 14.5 g in girls, and these intakes are low compared to the standard guidelines. The average intakes of energy and protein of the children were 84.5% and 114.0% of the Korean Recommended Dietary Allowances (RDAs), respectively. Besides energy, riboflavin, iron and calcium intakes were below the RDAs, and especially calcium intake was only 50% of the RDAs. On the other hand, thiamin, niacin, ascorbic acid, protein and phosphorus intakes exceeded the Korean RDAs. Family income or the children's body mass index (BMI) was not directly related to dietary fiber intakes. However, higher dietary fiber intakes tended to be related to higher intakes of green vegetables and fruits. Children with higher dietary fiber intake tended to prefer plant foods to animal foods. Energy and most nutrients, except heme iron and retinol, showed positive relationships with dietary fiber intake. Especially potassium and plant origin protein and calcium were highly correlated with dietary fiber intakes(r＞0.6). From these results, it is concluded that dietary fiber intakes of these sixth grade elementary school children were less than the standard reference and it is anticipated to decrease further in the future with increased incomes. Therefore, increased intakes of dietary fiber by elementary school children should be promoted through nutrition education, together with the development of cooking methods and recipes utilizing green vegetables and fruits.

The purposes of this study were to investigate the characteristics of lifestyle and dietary habits of the colorectal cancer patients in Daegu and Kyungpook areas and to collect the data useful for nutrition education for the prevention of colorectal cancer in this community. The case subjects of the study were 123 patients diagnosed recently as colorectal cancer at Kyungpook National University Hospital. The control subjects were 182 persons who did not have any gastrointestinal diseases, including the patients from the department of orthopedic surgery and healthy volunteers. The survey covering general characteristics, life style, dietary habits, eating behaviors, and food intake frequency was administered by individual interviews using questionnaires. The results of the study suggest that high BMI, daily life stress, pessimistic personality, lack of physical activities, and familial cancer history might be the possible risk factors for the incidence of colorectal cancer. Dietary factors suspected as risk factors for colorectal cancer in the present study included strong preferences to meats, salty and fatty taste foods, low intake of water, alcohol drinking, smoking, coffee intake and irregular eating habits. A high consumption of seaweeds, green-yellow vegetables, light-colored vegetables, and green tea was suggested as a preventive factor for colorectal cancer. It is recommended to conduct more extensive and systematic surveys in the near future to reconfirm the risk factors of colorectal cancer in consideration of the characteristic food culture in this community. The results of the present study may be applied to nutritional education for the prevention of colorectal cancer for the local residents. (Korean J Nutrition 38(2): 125～143, 2005)

This study was conducted with 375 workers in Changwon to examine the effects of working patterns on dietary habits and health. A self-administered questionnaire was conducted July 22 October 30, 2019. According to the results of the dietary habits and health related factors analysis, non-shift administrative workers showed significantly higher rates of green tea intake (p<0.05), and shift production workers showed significantly higher smoking rates (p<0.001) and waist circumferences (p<0.01). According to the results of the Pearson's correlation coefficient analysis, work hours showed negative correlations with job satisfaction (r=0.22, p<0.01) and positive correlations with perceived stress level (r=0.14, p<0.01). Temporary workers showed negative correlations with feel job satisfaction(r=0.14, p<0.01), perceived stress level (r=0.12, p<0.05), and concern about health (r=0.13, p<0.05). Diabetes showed positive correlations with hypertension (r=0.20, p<0.01), low HDL cholesterolemia (r=0.22, p<0.01), abdominal obesity (r=0.13, p<0.05), and hypertriglyceridemia(r=0.22, p<0.01). Based on these results, this researcher proposes that continuous attention and support of industries and communities are necessary for nutritional education and counseling relative to improving workers' dietary lives as well as disease prevention and control.

BACKGROUND/OBJECTIVES: The prevalence of food allergies in Korean children aged 6 to 12 years increased from 10.9% in 1995 to 12.6% in 2012 according to nationwide population studies. Treatment for food allergies is avoidance of allergenic-related foods and epinephrine auto-injector (EPI) for accidental allergic reactions. This study compared knowledge and perception of food allergy labeling and dietary practices of students. SUBJECTS/METHODS: The study was conducted with the fourth to sixth grade students from an elementary school in Yongin. A total of 437 response rate (95%) questionnaires were collected and statistically analyzed. RESULTS: The prevalence of food allergy among respondents was 19.7%, and the most common food allergy-related symptoms were urticaria, followed by itching, vomiting and nausea. Food allergens, other than 12 statutory food allergens, included cheese, cucumber, kiwi, melon, clam, green tea, walnut, grape, apricot and pineapple. Children with and without food allergy experience had a similar level of knowledge on food allergies. Children with food allergy experience thought that food allergy-related labeling on school menus was not clear or informative. CONCLUSION: To understand food allergies and prevent allergic reactions to school foodservice among children, schools must provide more concrete and customized food allergy education.

Objectives: This study was conducted to observe recent changes in adolescents' dietary behavior and indirectly evaluate the effects of the government's nutritional policies in Korea. Methods: We analyzed the secular trends in seven dietary behaviors using the Korea Youth Risk Behavior Web-based Survey data from 2005 to 2009. Through literature review, we included the policies implemented for the improvement of adolescents' dietary behaviors during the same periods. Results: The significant linear trends were observed in all dietary behaviors (p<0.05). Overall, all behaviors except the fruit intake rate were desirably changed during five years but undesirable changes were observed between 2008 and 2009 in all behaviors. Within those periods, several policies were implemented including 'Ban on carbonated-beverages in school', 'Green Food Zone', etc. Despite confirmed evidence of their effects, the policies on individual behavior such as nutrition education didn't influence the prevalence of dietary behaviors because they were conducted to too limited persons. Polices on the school environmental improvement, such as ban on carbonated beverage in school, were more effective because they decreased the exposure of undesirable food environment. However, for effect of Green Food Zone improving community environment we couldn't come to a conclusion because of too short period after full implementation. Conclusions: Among government nutrition policies conducted from 2005 to 2009, those on environmental improvement, especially in school, were more effective than those on individual behavior. Therefore, the development and implement of policies on school environmental improvement are needed in Korea.

The purpose of this study was to examine the effect of nutrition education about the Korean food guide to middle school students on food intake measured by food frequency. Three hundred first graders were sampled from two coeducational middle schools located in the small city of Chungnam area, and divided into 167 (74 boys, 93 girls) education groups of one school and 133 (70 boys, 63 girls) non education groups of the other school. Nutrition education was given to the education group for a total of 16 hours and no education to the non education group during the same period. After education, average nutrition knowledge scores of education group increased from $6.40\pm2.17\;to\;6.81\pm1.56$ significantly especially boys with a high range of increase and girls no increase. Dietary habit scores improved significantly from $46.2\pm6.5\;to\;49.1\pm6.2$ in both boys and girls of education group. Of the knowledge and dietary habits, ability of choosing a balanced meal, biased eating to some food, and taking diverse foods at every meal improved significantly in education group. In non education group no significant increases of either nutrition knowledge scores and dietary habit scores were shown. In addition education group showed significant increases after education, in the intake frequencies of rice$\cdot$noodle$\cdot$loaf bread, kimchi, green and yellow vegetables, and soybean$\cdot$soybean curds by 0.27, 0.23, 0.40 and 0.32 servings per day, compared with non education group. These changes were greater in girls than in boys. According to these results, it can be concluded that nutrition education about the Korean food guide improved effectively not only student's nutrition knowledge and dietary habits, but also healthy food intake ability. It is necessary to prepare long-term and continuous school-based nutrition education programs for the students to get into a habit of healthy food intake.

The purpose of the present study was to measure the dietary folate intake of Korean women of childbearing age. Folate intake obtained from 24-hour recall method and food frequency questionnaire was assessed in two hundred and ninety-three nonpregnant and non-lactating healthy women of childbearing age. The mean folate intake of women aged 20-29 was 112.8ug/day, 49.3% of their recommended level of 250ug/day. Folate intake of women aged 30-49 was 129.0ug/day, significantly higher than that of participants aged 20-29. A quartile analysis on the folate intake revealed that there significant differences in the consumption of dark green, leafy vegetables (p<0.01), other vegetables (p<0.01), and fruits and legumes(p<0.05) between the highest of childbearing age is far from adequate. To reach of the present study show that the folate intake of Korean women of childbearing age is far from adequate. To reach the recommended intake level of 250ug/day for women of childbearing age, folate supplementation and special nutrition education promoting folate intake might be necessary.

This study was to obtain information about the dietary habits, the dietary attitudes, nutrition knowledge, and the food consumption of middle school students and to assess relationships between the dietary habits, the dietary attitudes, and nutrition knowledge of middle school students. Data were collected from 390 middle school students in Kimcheon. In the dietary habits, the regularity of breakfast showed the highest point and the snack consumption showed the lowest point. Female students were lower in the regularity of breakfast, and male students were higher in overeating of dinner and night. In the dietary attitudes and the perceived importance of nutrition, male students showed more favorable attitudes and perceived more importance of nutrition. In the nutrition knowledge, the responses to items 'Cola or cider doesn't have calories' and 'An egg contains lots of cholesterol' were the lowest point. Female students had higher knowledge than male students. In the food intake, grains, milk.yogurt.cheese, and fruits were always eaten or frequently eaten. While fast food, spicy and salty food, seaweeds, carbonated drinks, and yellow or green vegetables were eaten in lower frequency than other foods. Male students consumed more meat.ham.egg.fish, fried.stir-fried food, fast food, carbonated drinks, and spicy and salty food than female students. The correlation between dietary attitudes and dietary habits was statistically significant. The correlation between dietary attitudes and the perceived importance of nutrition was statistically significant. But the correlation between dietary attitudes and nutrition knowledge was statistically significant for female students, not significant for male students. Nutrition knowledge was related to the perceived importance of nutrition. It might be suggested that effective nutrition education program might be developed and implemented to ensure the good eating behaviors of middle school students.

Objectives: The study was performed to examine the dietary behaviors and life stress of middle school students in the Gyeonggi area. Methods: A total of 580 middle school students (295 males, 285 females) in the Gyeonggi area participated in the study between July and August in 2011. The study was a questionnaire-based survey that included dietary habits, dietary behaviors, and life stress. Results: For dietary habits, the score for drinking milk was higher in male students than in female students, whereas the score for eating fruits was higher in female students compared to male students. There were significant differences in foods eaten and preferred under stress between male and female students. Male students showed significantly less changes in the number of meals, amount of meal intake, number of snacks, snack intake, frequency of overeating, and appetite during stress than female students. Life stress score of students largely came from academic factors, and female students showed higher stress levels in personal and surrounding environment factors than male students. Life stress score was significantly lower in students with high and moderate levels of dietary habits than in students with a low level of dietary habits. Total score for dietary habits and scores for eating adequate amounts of foods for each meal, considering a combination of food groups at each meal and eating green and orange vegetables, were significantly negatively correlated with life stress score. Life stress score was significantly negatively correlated with meal regularity and positively with the level of overeating. Conclusions: This study may provide basic information on dietary habits and life stress according to gender and the relationship between dietary behaviors and life stress of middle school students, and it suggests gender-based nutrition education programs to solve undesirable dietary habits and dietary behaviors in students with higher stress.
