The purpose of the study was to examine health-related behaviors and nutrient intake in relation to job stress level of police officers. Total of 166 police officers working in Jeonbuk area participated in the study. The study was conducted from February to March, 2009. Subjects were given self-administered questionnaire on their general health status, dietary and health-related habits. Nutrient intake was assessed by semi-quantitative food frequency questionnaire. Subjects were divided into four groups (very low, low, high, very high) by their job stress level scores. Main concerns of job stress were from 'job demand', 'organizational system' and 'lack of reward'. More than 95% of the subjects were confident of their health status. Health habits, such as drinking, smoking and exercising, were better than that of average Korean men. There were significant differences in dietary habits in relation to job stress level. Lower job stress group showed lower rate of skipping breakfast (p<0.01), more affordable meal time (p<0.05) and better snacking habits (p<0.001). Sweet food preference was higher in lower job stress group (p<0.05). The average calorie intake was $2063\pm532.7$ (88.5% of EER) and there was no significant difference in nutrient intake among job stress levels. However, mean intake of calcium and vitamin $B_2$ was less than 75% of %DRI in higher job stress group. Therefore, further support in nutritional counseling programs to improve dietary behaviors and health habits and to reduce job concerned stress of the police officers will be necessary.

In this study, we examined family history of chronic diseases, food group intake and physical activity in $5^{th}\;and\; 6^{th}$ grade elementary school children. Food group intake was compared with the KDRI food guides for children. The measurements of daily physical activity, television viewing, computer use, and daily servings of five food groups, including grains, meats, dairy products, fruits, and vegetables, were based on child and parent self-reports. As indices of obesity, the obesity index(%) and BMI(Body Mass Index) were used. The results were as follows. In boys, 83.2% were normal weight with 7.4% slightly obese, 7.4% moderately obese, and 2.0 were highly obese while the percentages of normal and slightly obese in girls were 89.9% and 6.2% respectively (p<0.05). The boys had more hours of daily physical activity(p<0.05) and more hours of computer usage(Internet searching or games)(p<0.05) than the girls. Slightly over 50% of the subjects met the daily recommended servings of grains, dairy products, fruits, and vegetables according to the KDRI food guides. However, only 26% of boys and 27% of girls met the recommended daily servings of protein foods such as meats, beans, and eggs. Thirty two percent(32%) of girls consumed high fat snacks everyday while 32% consumed high sugar snacks every day. The girls consumed more vegetables(p<0.05) and more high sugar snacks(p<0.05) than the boys. The children with family histories of obesity showed greater obesity rates(p<0.05) and sedentary lifestyles(p< 0.05) than those children without a family history of obesity. Children with family histories of high blood pressure consumed more sewings of vegetables and high fat snacks than the controls(p<0.05). The children with family histories of obesity consumed more high sugar or high fat snacks than the controls(p<0.05).

The time 18 months after birth is very important for the prevention of early childhood caries because this time is proper to assure the completion of weaning and to perform the diet counseling, and caries process is initiated or actively aggravated under the total influence of feeding pattern from this period. For the purpose of examining the infection status of Streptococcus mutans and Lactobacillus of 18 month old infants and their mothers, and analyzing the correlation between infection status versus various caries-risk factors, this study was performed on the 60 infants of 18 months old and their mothers through the microbiological screening of saliva samples and direct questionnaire to mothers about the caries risk factors. And the results were as follows, 1. The higher the mother's infection level of S. muntans, the higher the infant's infection level and transmission rate. 2. Compared with non-caries group, higher infection level of S. mutans in both infants and mothers and transmission rate were revealed in caries group. 3. The higher the infant's infection level of S. mutans, the higher the caries prevalence and deft values, the less the monthly income of the parents, the longer the period of breast feeding, and the higher the consumption rate of sugared snacks. 4. Most of Lactobacillus infected infants were revealed to be infected also with S. mutans and to have caries. 5. The higher deft value, less parents' monthly income, more frequent daily nursing and more irregular snacking patterns were found among Lactobacillus infected group compared with not-infected group.

The purpose of this study was to investigate the sweets preference, food frequency, dietary habits, and nutrition knowledge of middle school students who like sweets. A survey instrument consisted of a self-administered questionnaire, a food frequency questionnaire, and anthropometric measurements. Three hundreds thirty five students aged 13 to 15 years old were divided into two groups, Sweets Liking Group (SLG) and a control group based on the subjects' scores for dietary habits, sweets preference, and food frequency. For dietary habits, the score for meal regularity was significantly lower in the SLG group compared to the control (p<0.001). In addition, the SLG group was more likely to skip breakfast (p<0.001), eat inadequate amount of meals (p<0.001), and consume yellow-green vegetables less frequently (p<0.001) than the control. The subjects' nutrition knowledge was assessed using 20 questions representing five categories, including functions of nutrients, nutrition and health, food pyramid and food groups, healthful snacking and the right dietary attitude. The total scores for nutrition knowledge indicated that the SLG had a poorer nutrition knowledge for all five categories than the control (boys p<0.05, girls p<0.01). For food frequency, the SLG consumed more sweets but less grains, cereals, fishes, beans, vegetables, and milk and milk products than the control (p<0.001). Strong positive correlations appeared between sweets preference, sweets frequency, and sweets-related dietary habits; and all were negatively correlated to nutrition knowledge. Sweets frequency was negatively related to meal regularity, breakfast consumption, meal adequacy, and balanced meals. The findings suggest that nutrition education is necessary to improve the dietary pattern, especially sweets consumption, of Korean young adolescents.

The dietary habits of 156 female college students in the Department of Food and Nutrition (n=79) and other departments (n=77) at Sahmyook University, Nowon-gu, Seoul were evaluated from September to December, 2009. All participants completed a questionnaire designed to determine the mini dietary assessment score, as well as to evaluate nutrient intake, healthrelated questions and to determine a physical score. The students in the department of food and nutrition tended to consume more vegetables than Kimchi for each meal (39.2%), fried foods twice a week (38.0%) (p<0.05) and less fruits and fruit juices (29.1%). In addition, 15.2% of students ate Samgyeopsal and Galbi less than two times a week (p<0.05). The subjects in the department of food and nutrition took less vitamin $B_1$ and more vitamin C and E than the subjects in the other departments (p<0.05). All subjects regularly exercised for 30 minutes to 1 hour (45.7%), one or two times weekly (43.5%). The subjects in the other departments consumed more nutrient supplements. Overall, 69.1% of the subjects consumed nutrient supplements. A total of 87.8% of the subjects in the other departments consumed alcoholic beverages and all subjects began to drink when they were in high school (50.4%). The primary reason given to continue drinking was to maintain good relationships with friends (76.7%). Overall, the results of this study indicate that students in the department of food and nutrition of Sahmyook university have better dietary habits and nutrient intake than those in other departments. The results highlight the necessary to introduce a practical method of inducing good dietary habits to the everyday life of students. One approach may be to provide greater opportunity for students in other departments to attend classes in the department of food and nutrition.

The purpose of this study was to develop a nutrition education curriculum with teacher's guide which includes discretionary activities for obese children. A survey was carried out to investigate the recognition of body image and food behaviors according to the obesity index (mild, moderate, severe) in school children (4~6th grade, 158 boys and 60 girls) who were selected based on a physical examination in May, 2006 in the Gyeongnam province. Next, a nutrition education curriculum with teacher's guide was developed on the basis of the findings from the survey and from preceding researches. The results are summarized as follow. The results of this study showed the existence of some nutritional problems such as overeating, prejudice, skipping meals, snacking patterns, etc, which indicate the need for nutritional management for obese children. Most overweight children (80.3%) showed the most interest in the nutrition education program, particularly with regards to dieting for weight control (64.7%). The developed nutrition education curriculum consisted of 8 main subjects and 13 subtitles. The curriculum was prepared for 13 lessons and included songs and singing, making-up lyrics, games about nutrition, discussions of the experience of eating (satiety, thirst, hunger), debates on dietary habits, writing and others to promote the interest for learning. We aimed to develop this program in an attempt to improve the dietary habits of obese school children. This is very important because once a dietary habit is formed in adults, it is difficult to change and the best adjustable stage is during childhood. Therefore, early nutrition education during elementary school can change and build-up the awareness of health in young elementary school children.

We studied the nutritional status of on mentally handicapped children living at home or in institutions since early teenage years are nutritionally important. The subjects of 7 to 12 year old mentally retarded children attenending a special education school in Seoul were surveyed with questionnaires as well as 2-day dietary recall records, with the help of persons of their care-giver when needed. Among the 64 children,54.7% are living in institutions and the rest of them are living at home. They were ranged from the trainable (64.1%) , the educable (26.6%) , and the non-trainable (9.4%) . Their average daily intake of energy intakes (%RDA) was 2,070.1 kcal (94.1%) , Ca 603.9 mg (75.5%) , Fe 11.1 mg (92.5%), Vt.A 507.5 RE (84.6%) , Vt. B$_2$.1g (88.2%), niacin 14.1 g (93.6%) and Vt. C 58.2 g (83.1%) . Their average intakes of these nutrients were significantly higher in subjects of institutions than at home. The nutrients consumed at a much higher level than the RDh of the normal children were Vt. B, (1.6 g,146.8%) and protein (75.3g, 136.9%) . The higher percentage of children at home were under consumed of several nutrients (< 75% RDA) than ones in institutions. When comparing the degree of handicap, energy and nutrient intakes except Vt. C were highest in educable children than trainable ones or Dawn's children. MAR of the diets of the subjects was 0.84. Children at home showed lower MAR as well as NAR of each nutrients, whereas children belonged to INQ < 1 were less at home. Handicapped children at home were snacking higher amount relative to their calorie intake and too frequently, that may lead to their poor nutrition. There was positive correlations between factors of nutrition and physical and dietary behaviors, but there were no correlations between factors of nutrition and health-related habits. Nutritional caring mentally handicapped children in institutions seemed to be more effectively managed.

Purpose: This study examined the relationship among the use of food-related content (FRC), dietary behaviors, and dietary self-efficacy to demonstrate the need for nutrition education to help adolescents build healthy eating habits and provide evidence for developing nutrition education programs for adolescents. Methods: Three hundred and eighty-one high school students in Seoul and Gyeonggi areas participated in the study. The subjects were divided into three groups (low, medium, and high) according to the level of use of the FRC, and their general characteristics, dietary behaviors, and dietary self-efficacy were analyzed. Correlation analysis was performed between FRC usage, dietary behaviors, and dietary self-efficacy, and the mediating effects of dietary self-efficacy on the relationship between the level of the use of FRC and dietary behaviors were estimated. Results: A higher level of FRC usage was associated with an increased daily cost of eating out and snacking, but no difference was observed in the BMI range. The subjects in a group with a high level of FRC usage ate convenience store or instant foods instead of homemade meals (p = 0.033), had a late-night meal or snack (p = 0.024), and turned to emotional eating under stress (p < 0.001) more than those in the low level group. In addition, the high level group checked the nutrition facts label more carefully when purchasing processed foods (p = 0.016) and exercised at least 30 minutes daily, not considering physical education classes (p = 0.057). The higher level of FRC use, the lower the dietary self-efficacy, whereby the subscales 'environmental stimulus control efficacy' and 'affective factor control efficacy' showed complete mediating effects. Conclusion: Given that FRC has been increased recently, adolescents are in need of support to help them control and enhance their dietary self-efficacy as well as develop healthy dietary behaviors through proper nutrition education programs.

Purpose: This study examined the effects of a mobile app-based program to reduce the dietary sugar intake according to the stages of the behavioral change in dietary sugar reduction in female college students. Methods: The program used in this study can monitor the dietary sugar intake after recording the dietary intake and provide education message for the reduction of dietary sugar intake. In an eight-week pre-post intervention study, 68 female college students were instructed to record all the food they consumed daily and received weekly education information. At pre-post intervention, the subjects were asked to answer the questionnaire about sugar-related nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. For statistical analysis, ANOVA and a paired t-test were used for comparative analysis according Precontemplation (PC), Contemplation Preparation (C P), and A M (Action Maintenance) stage. Results: Significant differences were observed in the frequency of snacking, experience of nutrition education, and preference for sweetness according to the stages of behavior change in dietary sugar reduction. After finishing an intervention, the sugar-related nutrition knowledge score was increased significantly in the stages of Precontemplation (PC) and Contemplation Preparation (C P). The score of the sugar intake behavior increased significantly in all stages. The intake frequency of chocolate, muffins or cakes, and drinking yogurt decreased significantly in the PC stage and the intake frequency of biscuits, carbonated beverages, and fruit juice decreased significantly in the C P stage. Subjects in the PC and C P stages had an undesirable propensity in nutrition knowledge, sugar-intake behavior, and sugar-intake frequency compared to the A M stage, but this intervention improved significantly their nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. Conclusion: This program can be an effective educational tool in the stages of PC and C P, and is expected to further increase the usability and sustainability of mobile application if supplemented appropriately to a health platform program.
