The purpose of this study was to investigate the eating behavior, food preference and nutrition knowledge according to the body style of male college students. The subjects were 219 male students enrolled in University, Taegu. The data was collected by using a survey questionnaire and an anthropometric measurement. The results were summarized as follows: The mean height, weight and BMI of subjects were $173.8{\pm}8.7cm,\;65.8{\pm}7.9Kg,\;and\;21.9{\pm}2.4$, respectively. The subjects were divided into three groups according to the BMI: underweight group(<20); normal group(20-25); and overweight group(>25). One third of the subjects preferred to gain weight(33.8%); 47 subjects preferred to lose weight(21.5%); and the rest of the subjects satisfied their physique(44.7%). Most of subjects considered 'supper' as the most important meal during a day. Among the food items, the most frequently and evenly ingested item by subjects was 'Kimchi' : 'Ham and sausage' was the least preferred food among subjects. There was no significant difference in preference among three groups and almost half of the subjects had irregular meal time because of busy schedule. The preference for meat showed high score among underweight group; on the other hand, the preference for fruits and vegetables showed high score among overweight group. Usually subjects gained nutrition knowledge through media including newspaper, magazine and TV. There was no significant difference of the nutrition knowledge score among three groups. Based on these results, nutrition education program for the college student should be arranged in the classes.

Purpose: This study was conducted to examine the status of dietary behavior and its association with study-related factors in middle school students. Methods: Study-related factors, dietary habit score and dietary behaviors were surveyed by questionnaire and then analyzed. A total of 580 students in some middle schools in Gyeonggi-do participated in this study. Collected data were analyzed using SPSS for windows Ver. 22.0. Results: 71.3% of the subjects slept for 6 ~ 8 hours, and the studying time outside of school was the highest (2 ~ 4 hours). The highest score for stress from studying by private lessons or academies was 'seldom stressed', with higher stress being observed in male students than female students. The average dietary habit score was 3.69 in male students and 3.62 in female students. The highest average time for meal eating was 10 ~ 20 minutes, with shorter times being observed for male students than female students. Eating meals was regular in most students and the highest number of snack eating was 1 ~ 2 times a day. For dietary behaviors by study-related factors, students with more than 2 hours of studying time outside of school showed higher dietary habit scores than those with less than 2 hours, who showed significantly higher rates of eating 2 meals a day. As the sleeping hours and daily average studying hours increased, the rate of regular meal eating increased significantly. Conclusion: The students showed good, above average dietary behaviors, but gender differences in study-related factors and dietary behaviors. Moreover, the sleeping hours and the studying time outside of school were correlated with dietary habit scores and dietary behaviors. Thus, continuous and systematic education for proper dietary behavior is needed along with greater interest in students with problems of study-related factors, particularly those due to study burden.

Purpose: The prevalence of childhood obesity has increased dramatically. It is important to know about life style and dietary habits of the obese children because the treatment of childhood obesity focuses on using behavioral modification techniques. We aimed to develop a questionnaire for the purpose of providing convenient and useful guidance to pediatricians who evaluate and treat obese children. Methods: Previously developed questionnaire was given to 94 obese children and their parents who had visited clinic for obese children and adolescents. We analyzed response rates on questions and reliability between children and their parents. Results: The response rates on questions were somewhat high. Agreement of paired questions of both parents and children was also moderately high (63~92%). It is acceptable to complete questions by either parents or children alone. Items for hours of playing video games or computer, maternal job, kind of consuming beverage and food outside home were added. Conclusion: We concluded that some questions are not needed to be given to both parents and their children. It would be better to have parents record life style of their children and to have children record their food intake with physical activity outside home.

Cookies containing wheat flour mixed with 10, 30 or 50% esterified with octenylsuccinic anhydride (OSA, 3%) and dry-heated ($130^{\circ}C$, 2 hr) high amylose rice (Goami 2) starch (DH-OSAR) were prepared and then their physical and digestive properties were evaluated. When the amount of added DH-OSAR increased, the hardness and brittleness of the cookies decreased, and L (brightness) value increased. For the digestive properties, the cookies containing 50% DH-OSAR significantly increased the amount of slowly digestible starch (SDS), and decreased the amount of rapidly digestible starch (RDS), resulting in the lowest expected Glycemic Index (eGI) among tested cookies. Although the cookies containing DHOSAR were inferior to the control, the addition of xanthan gum (0.5% based on total powder amount) significantly improved their textural and sensory properties. Specially, the cookies containing 50% DH-OSAR and the addition of 0.5% xanthan gum showed the lowest eGI value, maintaining the improved textural and sensory properties.

Objectives: This study was conducted to examine the length of exposure to smartphone and its association with dietary behavior toward snacks, lifestyle, and nutrition knowledge in elementary school students. Methods: Subjects were 372 5th and 6th grade schoolchildren in Cheongju, Korea, and data was collected by a self-administered questionnaire. They were divided into two groups by the time spent using smartphone: moderate (< 2 hours/day) and overexposure (${\geq}2$ hours/day). Data was analyzed using frequency analysis, ${\chi}^2$-test, and independent t-test as well as analysis of covariance when necessary. Results: Approximately half of subjects (41.4%) reported spending ${\geq}2$ hours/day using smartphone. That habit was more frequent among students in the 6th grade, those who received more monthly allowance, and who has a working mother. 63.4% of the subjects reported that they consumed snacks while watching television, using a computer and/or a smartphone and 48.1% said that they consumed snacks while they use a smartphone. Both situations were most prevalent among those with overexposure to smartphone (${\geq}2$ hours/day). We also observed that a higher percentage of subjects from the overexposure group spent more money on snack foods with the preference for ice cream, fast food, and carbonated drinks. Further, those in the overexposure group consumed more ice cream, cookies, and carbonated drinks. In addition, they had less desirable dietary behavior and health-related lifestyle (sleep duration and frequency of regular exercise) compared to those with moderate smartphone usage (< 2 hours/day). However, there was no statistical difference in nutrition knowledge among children with different degrees of smartphone usage. Conclusions: Our results showed that longer smartphone use was associated with less desirable snack preference/consumption and other dietary behavior in elementary school students. Thus interest and positive attitudes towards healthy snacks and diet should be reinforced in nutrition education programs, especially for those who are prone to use smartphones.

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.
