This study was conducted to provide basic information on the nutritional status and dietary behaviors of the deaf teenagers. The subjects of this study were 87 deaf-mute high school students in Pusan and Kyung-nam area and, in comparison,90 general high school students in Ham-an area. The survey was investigated by using a self-administered questionnaire. The results were as follows: Deaf-mute group was consisted of 63.2% male and 36.8% female, and mean of height and weight of male were 171.2 cm and 61.9kg, female were 158.0cm and 51.7kg. Obesity index and body mass index (BMI) were normal range in both deaf-mute and normal groups. The average nutrition knowledge score of the deaf-mute group was 6.8 $\pm$ 1.5 out of possible 10 points, that was significantly lower than 7.3 $\pm$ 0.8 of the normal group (p<0.01). The mean of self-control and conscious control scores in the eating behaviors of the deaf-mute group were 2.6 $\pm$ 1.2 and 2.4 $\pm$ 1.3 out of possible 5 points from each item, which was significantly higher than 2.1 $\pm$ 1.3 and 1.8 $\pm$ 1.4 of the normal group (p< 0,01). Nutrients consumed below 90% of Korean RDA were energy (79.9%), Ca (71.5%) for deaf-mute male students and Ca (88.5%) for deaf-mute female students. Energy (71.4%), protein (87.8%), Ca (74.8%), vitamin B$_1$ (83.4%) intake of normal male students and energy (72.8%), Ca (71.2%), Fe (78.7%) intake of normal female students were below 90% of Korean RDA. Energy, protein, fat, vitamin B$_1$, niacin intake of deaf-mute male students were significantly higher than normal male students and all nutrients intake of deaf-mute female students were significantly higher than normal female students. By the correlation of nutrients intakes with nutrition knowledge, there was positive correlation with the intakes of Ca, Fe, vitamin A, vitamin B$_2$, and vitamin C in the deaf-mute group, while there was negative correlation with the nutrients intakes (except for protein and fat) in the normal group. The amount of meal, breakfast, regularity of meal time, frequency of snacks showed a positive relation to nutrient intakes in deaf-mute group and amount of meal, breakfast, regularity of meal time, frequency of overeating showed a positive relation to nutrient intakes in normal group. The nutrition knowledge had no correlation with food habits or eating behaviors in both groups.(Korean J Nutrition 35(9) : 982~995, 2002)

The purpose of this study was to obtain the nutritional values and objective data of uncooked powdered food (UPF) in korea. We interviewed 27 healthy female subjects aged over 25 years living in the lksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Their body compositions were measured using body fat analyzer. Also we conducted hematological and clinical analysis of blood. The intake of energy, lipid and protein has decreased as people started to take UPF, but the intake of vitamins and minerals has increased. The quality of meals has improved after taking UPF. Due to the energy loss by taking UPF, weight and body fat gradually lessened. Among the lost weight the percentage of the body fat was high and we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening body fat. The most positive change among biochemical changes by taking UPF was decreasing of serum lipid contents. The concentrations of total cholesterol and LDL-cholesterol gradually decreased and decreased intently after 12weeks. Serum HDL-cholesterol gradually increased and serum triglyceride showed gradual decrement. When healthy adult women replaced two of three meals with UPF for 3months, we were able to see some useful changes like decrement of body fat and serum lipid control and during this 3month period, no significant nutritional problems occurred. Complete judgement on UPF may be difficult with these conclusions but if people take a nomal meal once and replenish iron from taking UPF twice a day, we assume that replacing UPF with regular meal not be a problem in nutritional status. If other experiments on the effects of UPF proceed, we believe that those experiments will be very helpful in judging the nutritional value of UPF. (Korean J Nutrition 36(1) : 49-63, 2003)

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.

A computerized dietary prescription and nutritional counseling system for patients having hyperlipidemia has been developed using a personal computer. This system is composed of three programs. The first program is designed to investigate dietary history of patient, such as a dietary habit and a preference of food, to find out his incorrect dietary behavior and to give him some suggestions to correct dietary behavior. The second one is developed to analyze the energy and nutrients intake using 24-hour dietary recall method and also evaluate the status of dietary intake, especially the status of dietary fat. With these data, patient can replan pattern of his food intake including in-between-meal snack as well as regular meals. The third one is the diet and menu Planning program made using food exchange table. It provides the patient with a meal pattern suitable in his weight, activity and the other status of the body. Practicing these programs, patient with hyperlipidemia can help himself very conveniently in organizing his meal plan and in improving his dietary behavior.

BACKGROUND/OBJECTIVES: This study analyzed factors affecting consumption frequencies of vegetables and fruits in Korean adolescents. SUBJECTS/METHODS: Consumption frequencies of vegetables and fruits, general characteristics, meal, health, and other variables were analyzed for a total of 147,047 adolescents who participated in the KYRBWS (Korea Youth Risk Behavior Web-based Survey) conducted in 2006 and 2011 by the Korea Centers for Disease Control and Prevention. RESULTS: Consumption frequencies of vegetables and fruits more than once a day significantly decreased in 2011 compared to 2006 based on Chi-square test conducted for every factor employed in the study. Analysis of factors showed that consumption frequencies of vegetables and fruits were reduced in both study years as subjective income decreased, whereas intake frequencies increased with mother's education level and reduction of adolescent stress level. CONCLUSIONS: In general, consumption frequencies of vegetables and fruits decreased in 2011 compared to those in 2006. Thus, future research needs to improve dietary guidelines for nutrition education in order for students to recognize the importance of food consumption and necessity of increasing daily serving sizes of vegetables and fruits for their balanced consumption.

This study was conducted to find the gender and age differences in dietary behaviors and food consumption pattern of Korean American adults living in western parts of USA. The structured survey forms and self-administered food frequency questionnaire were used to assess dietary behavior and nutrient intakes. It was found that younger subjects kept their meal time more irregularly and skipped breakfast more often than older subjects due to lack of time. There were significant age differences in skipping meals, kind of skipping meals, and the reasons for skipping meals. Young subjects consumed more American type food while older subjects consumed more traditional Korean food. Nutrient intakes of males' except for the elderly were significantly higher in energy, protein, Fe and P than those of females'. Vitamin A and vitamin C intake were significantly higher in females. Energy ratio of carbohydrate: protein: fat was 56.2 : 16.8 : 27.0. Females consumed more plant food as their dietary sources of protein, fat, Ca and Fe, compared to males. Ca intakes of participants' were below $75\%$ of RDA except for the youngest male and $30\~49$ aged male and females. Futhermore, Ca intake was below $70\%$ after age 50 in both genders. Effective nutrition education program targeting Korean Americans in the community should be developed and implemented to increase Ca consumption.

The purpose of this study was to survey several aspects of health and food related behavior of college students in Wonju area. Questionnaires were delivered personally to 430 students. The 37.9% of subjects were self-boarded and 27.4% lived in their home in Wonju area. They spend 230,000 won in average per month. Male students spent money more than female students and self-boarding students spent money more than other residental type students. The 90% of subjects thought they were healthy and the 25% of subjects exercised regularly. The subjects self-recognized their body as fat were more concerning about their weight control and had more weight control experience. SeIf-boarding students tended to skip their meals and had unbalanced diet. Students who lived in dormitory tended to skip meal less. Female students showed higher scores at balanced diet, snack intake, and left meal than male students. Self recognized their body as medium showed lower scores at overeating and eating irregularly. The amount of consumption of carbonated beverage was the highest among several instant foods. The frequencies of intake of those instant foods were different by gender, residental types, and eating behaviors.

The purpose of this study was to explore the relationship between dietary behavior and the nutrient intake status in the youth of rural areas, based on their personal characters such as their sex, age, family type, number of family members, mother's age, occupation, and school career. This study was made by use of a self-administrated questionnaire with a 24-hour recall for 5days as an instrument with 439 randomly selected students. Statistical methods applied to analyze the data were frequency, percent, Willcoxon Rank-sum test, Kruskal-wallis test, x2-test by contingence table, and Spearman's correlation coefficient in non parametric statistical cases. Some of the interesting results are as follows : 1) The correlation between sex and breakfast is highly significant. That is, over 80% of male students had breakfast every day, whereas only about 60% of female students had breakfast every day. Bad table manners and some other problems are insignificant with respect to the personal characters in the relations between the personal characters and eating behaviors. However, the regularity of every meal, the frequency of having meals with other family members, and the frequency of meals eaten out and snacks show significant differences. 2) The mother's occupation does not have any influence on the nutrient intake of their students when the relationship between personal characters and nutrient intake was analysed. On the other hand sex, the mother's school career, the numbers of family members, the type of family, and the income of the family showed significant differences nutrient intakes. 3) The regularity and the frequency of having meals, meals eaten out with their family members, and the table manners during meals showed significant differences in the intake of nutrient elements such as calorie, protein, fat, fiber, calcium, iron, phosphorus, vitamin B1, vitamin B2, niacin and vitamin C. However some consideration during meals and problems in eating habit are insignificant with regard to nutrient intake.

The purpose of this study was to investigate the nutrient intake, eating behaviors and health-related lifestyles of Korean non-nutrition major college students after they took a nutrition course. The subjects were 40 male and 147 female students at a university in Inchon. The results are summarized as follows: Average height of male and female students was 176.2 and 162.0 cm, respectively. Average weight was 66.2 and 52.3 kg, respectively. Average intake of calories, protein, vitamin A, vitamin C, vitamin $B_1$, vitamin $B_2$, niacin, and Ca was lower than Korean RDA. Fe intake of female students was lower than Korean RDA. Most students have had dietary problems such as overeating, eating unbalanced meals, and skipping meals. More than 60% of the students skipped breakfast. The main reason for skipping meals was lack of time. Most students didnt exercise regularly. About 40% of the students took vitamin or mineral supplements. As for smoking and alcohol use, 11.3% of the students drank alcohol and smoked, and 74.2% of them only drank alcohol. More than 30% of the students drank alcohol once a week. Most students ate out twice a week, and chose their based on taste rather than nutritional value. The main reason for eating out was simply to enjoy a meal. More than 60% of the students ate at places in or around campus. After taking the nutrition course, intake of milk and other dairy products, vegetables, fruits and protein-rich foods increased in female students. For both male and female students, intake of fat, sugar, processed foods, soft drinks, fried foods and spices decreased. Therefore, nutrition education had effect on non-nutrition major students, suggesting that proper nutrition education encouraged healthy eating habits on the part of college students.
