Differences in dietary habits between Korean smokers and non-smokers were investigated using information obtained from 7,370 adults, aged 20 years and older who participated in the 1998 Korean National Health and Nutrition Sulvey. Dietary habit data including: skipping of meals, meal regularity, meal volume, snacking habits, removing fatty portions before eating foods, and dietary supplement intake were collected using a structured questionnaire by interview. Individual smoking data was also collected by interview as part of the health behavior survey. A Chi-square test was used to test the association between the dietary habits and smoking. 66.9% of the men were smokers (daily current or occasional current), while only 6.7% of women smoked. On average, 34.7% of the subjects were smokers. Smokers were more likely than nonsmokers to engage in the following dietary habits considered unhealthy: skipping breakfast, meal irregularity, large dinners, small breakfasts, frequently eating out, and eating food without removing the fatty portion. Therefore, Korean smokers should be provided education to assist them in making healthy dietary choices such as: eating regular meals, small dinners, and removing fatty Portion of foods. The survey also revealed that a substantial percentage (about 20%) of the subjects were taking some kind of dietary supplement, regardless of smoking status. It is, therefore, alto necessary to inform the general public that a balanced diet is the ideal way to obtain nutrients for optimal health.

We studied teachers' breakfast habits and their preferences on various breakfast types so that we will furnish data to nutrition education including ideal breakfast habit and development of various menus. The meal considered as most importantly were dinner (66.2%), fellowed by lunch(21.6%), all three meals(6.4%) and breakfast(5.8%). Men considered breakfast more importantly than women. On the contrary, women considered dinner more significantly compared to men. The group aged 45 and over emphasized breakfast and all three meal. 78.1% of subjects answered that breakfast is necessary and 61.5% of subjects ate breakfast regularly. Those who have breakfast regularly was lower in women(50.0%) than in men(71.3%). Instead, those who eat breakfast irregularly or skipping it was higher among women(50.0%) than among men(29.7%). The percentages of having breakfast regularly was higher in older groups. For breakfast, 82.1% of subjects had conventional meal which included rice, soup and Kimch. On the other hand, 13.9% of subjects had Western style breakfast such as bread, cornflakes and milk. The major reason for eating breakfast regularly was answered as 'maintain health(71.8%)'. The major reason for eating breakfast irregularly or skipping was 'don't have enough time to eat(48.0%)', 'poor appetite(28.6%)'. The major physical discomfort after skipping breakfast was 'experience brash(35.6%)', 'lack of physical strength(35.1%)'. Subjects answered that breakfast served as 'source of physical strength(64.9%)', 'provides nutritional balance for a day(21.1%)' and 15.0% of subjects ate out breakfast. Therefore, it is suggested that teachers as well as school children be provided breakfast and snack in school. The preference and opinion regarding breakfast types wer conventional food including rice, soup and Kimch(67.0%). There was a little preference in Western style food such as bread, milk and coffee(14.3%), cereals mixture and porridge(10.7%). It was noticeable that 49.1% of females and those who reside in Seoul(42.2%) selected various breakfast types excluding conventional food. Therefore it will be accepted to working women as breakfast if it is nutritionally balanced and cook well in short time.

BACKGROUND/OBJECTIVES: Adolescents who skip breakfast have an increased prevalence of chronic diseases. Thus, we aimed to evaluate whether the intake of rice-based breakfast had positive effects on blood glucose indices and to determine the possibility of diabetes prevalence in Korean youths who habitually skip breakfast. SUBJECTS/METHODS: In this randomized parallel-group controlled trial, 81 subjects who were suitable for compliance among 105 middle-and high-school students aged 12-18 years who usually skipped breakfast were included in this study (rice-meal group [RMG], n = 26; wheat-meal group [WMG], n = 29; general-meal group [GMG], n = 26). The RMG and WMG received a rice-based breakfast and a wheat-based breakfast for 12 weeks, respectively. The anthropometric indices, blood glucose indices, and metabolites were measured at baseline and the endpoint, respectively. RESULTS: The mean body weights in the RMG, WMG, and GMG groups at the endpoint were 62.44 kg, 61.80 kg, and 60.28 kg, respectively, and the mean body weights of the WMG and GMG groups at the endpoint were significantly higher than that at baseline (P < 0.05). The levels of fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) values were significantly decreased in the RMG group at the endpoint compared to baseline (P < 0.05, P < 0.05, respectively). The levels of tryptophan and tyrosine in the WMG group at the endpoint were significantly higher than that those at baseline (P < 0.01, P < 0.05, respectively). CONCLUSIONS: Rice-based breakfast has positive effects on fasting insulin levels and HOMA-IR in Korean adolescents who skip breakfast. Additionally, it was found that a skipping breakfast could increase the prevalence of diabetes in adolescents who skip breakfast. Therefore, in addition to reducing breakfast skipping, it is vital to develop a rice-based menu that fits teenage preferences to prevent chronic diseases such as diabetes.

The purpose of this study was to provide fundamental data on the importance of eating breakfast by analyzing the dietary habits, dietary attitude, dietary behavior, and nutrition knowledge between of male high school students according to breakfast eating status. The subjects consisted of 400 male high school students living in Chungnam. There was no significant difference according to grade, height, and weight between students who skipped breakfast and those who ate breakfast. Further, satisfaction and perception about body weight were not statistically different between the two groups. Regarding relationships with friends, to the response 'I have a lot of relationships with friends' was 25.5% in the skipping breakfast group and 45.7% in the eating breakfast group. The academic records of the students who ate breakfast were much higher. Meal regularity, meal satisfaction, and dietary attitude of the eating breakfast group were better than those of the skipping breakfast group. Regarding the level of nutritional knowledge, students who skipped breakfast scored $7.6{\pm}2.9$ points while the students who ate breakfast scores $7.9{\pm}3.1$ points, indicating no significant difference. The students who ate breakfast had better friendships, higher academic achievement, and better dietary behavior and attitude. Therefore, it is necessary to increase nutrition education and reduce the skipping of breakfast through a variety of methods, such as school food service and simple recipes for Korean food. It should also be considered that nutrition education for parents be widely provided.

An ecological study of food and nutrition was conducted among 198 children, 6 to 12 years old, of the Songmyun elementary school and Samsong elementary school, located in remote villages of Chungchun-myun, Goisan-gun, Chung Buk Province between July 11 and 16, 1988. The results were summarized as follows. In regard to frequency of skipping breakfast, 3.3% of subjects skipped every morning; 15% often skipped; and the others never skipped. The most common reason for skipping a meal was lack of appetite. 6.6% of subjects often skipped an evening meal because of delayed meal preparation by a mother who returned home late. The survey found that 5.1% of subjects skipped a lunch at school. The reasons for skipping lunch were the mother’s being too busy to prepare a boxed lunch; a school bag too heavy to carry for a long distance to school; no adequate side-dishes for the boxed lunch. Growth patterns of those children having poor food habits, were reflected in lower figures in arm circumference and weight for height. The percentage of children having meals with their family on weekdays was 84.7% for breakfast; 85.6% for evening meal. About 7% of subjects had many dislikes and 74.1% had some dislikes in what they ate; 18.9% had good food preferences. There was a strong correlation between appetite or food preferences and anthropometric measurements or nutrient intake. Boiled rice was the predominant dietary staple, and principal sources of protein taken by subjects at home were soy beans and soy products. Regarding the boxed lunch prepared at home, most popular was one with only one kind of side-dish, including kimchee. 43.4% of the side-dishes were prepared with vegetables only. As for between meal snacks, milk and milk products, fruits and breads were popular among the subjects. The survey found that the children liked fruits, yogurt, corn, Chajang noodle; in contrast, lowest preference was for soup made with bones, curried meat with rice, and aromatic vegetables. The survey discovered a local dietary characteristics; 46.2% of the children customarily ate frog meat, an unconventional food.

The purpose of this study was to investigate the difference in dietary attitudes, dietary behaviors and health-related lifestyles among Korean college students (392 males, 808 females) participating in a web class of nutrition education. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. Most female subjects with weight-control attempt had eating habit problems such as overeating and food jags. The female subjects with weight-control attempt showed significantly higher rate of skipping dinner compared to those without weight-control attempt. As for frequency of exercise, the subjects with weight-control attempt exercised more frequently compared to those without weight-control attempt. In subjects, weight-control attempt was significantly associated with exercise. Nutrient adequacy ratio and mean adequacy ratio of the subjects with weight-control attempt were significantly lower compared to those without weight-control attempt. These results suggest that skipping dinner or exercise might be used as weight-control methods in Korean college female students participating in a nutrition education class via the internet.

The purpose of this study was to evaluate nutrient intake and meal variety with breakfast eating in Korean adolescents using data from the 2008-2009 National Health and Nutrition Examination Survey. The analysis included 1245 adolescents aged 12 to 18 years. The subjects were divided into two groups according to breakfast skipping (BS: breakfast skipping, n = 235, BE: breakfast eating, n = 1110). The BS group was significantly higher in its frequency of eating soda drinks, instant noodle, and ice cream than the BE group. The BS group consumed significantly lower quantities of plant calcium and plant protein per 1,000 kcal compared to the BE group. Also the intake of cereal and vegetables in the BS group was significantly lower than those in the BE group, however, the intake of beverage in the BS group was significantly higher than that in the BE group. The average number of foods of the BE and BS groups were 29.50 and 25.85, respectively and revealed a statistical significance (p < 0.0001). The snack intake and % energy from snack intake of the BS group were significantly higher than those of the BE group. Also, the fasting blood glucose concentrations were significantly higher in the BS group compared to the BE group. In conclusion, adolescents who skip breakfast may have lower meal variety and higher blood glucose concentrations. Therefore, in support of proper dietary management, it is necessary to promote and encourage breakfast eating.

The purpose of this study was to evaluate the dietary behaviors as well as energy and nutrient intake in elementary and middle school students according to breakfast eating status. The survey was conducted using questionnaires and dietary records among 191 elementary school students and 280 middle school students residing in Chungnam. The subjects were divided into two groups according to frequency of eating breakfast: breakfast skipping (frequency of eating breakfast under 4 times/week) and breakfast eating (frequency of eating breakfast over 5 times/week). The rate of breakfast skipping was 27.2% for the elementary school students and 31.1% for the middle school students. The breakfast skipping group had a significantly lower frequency of having dinner, a lower proportion of eating at regular meal times, and a significantly higher frequency of leaving food after meals than the breakfast eating group for both elementary and middle school students. In the case of the elementary students, there was a significant difference in carbohydrate intake between the two groups. In the case of the middle school students, the intakes of energy, protein, carbohydrate, dietary fiber, vitamin A, vitamin B2, niacin, vitamin B6, folate, vitamin C, Ca, and Fe in the breakfast skipping group were significantly lower than those in the breakfast eating group. These results show that nutrient deficiencies among breakfast skipping individuals cannot be compensated for at the other meals during the day in middle school-aged adolescents whose nutrient requirements are high for growth. Therefore, in support of proper dietary management, it is necessary to promote and support breakfast eating in adolescents.

The goal of this study was to determine the nutritional value and nutrients provided by each meal and snack of consumed by university students. Subjects were randomly selected from volunteer students at five universities in Ankara. A sample of 400 students (167 female and 233 male) aged between 19 and 24 years participated in this study. A questionnaire designed to assess general characteristics, anthropometric measurements, and 24 hours dietary records was administered using face to face interviews. According to body mass index classifications, 69.5% of male students, and 77.7% of female students were found to be in the normal weight categories. Overweight categories were found to be 25.1% and 5.6% for males and females, respectively. Breakfast and lunch were the most frequently skipped meals, with a total of 47.7% of students skipping breakfast and 25.2% skipping lunch. The percentages of energy deficiency were found to be 78.4% in males, and 81.1% in females. Dinner was the main meal for consumption of energy and the other nutrients, except saturated fatty acids, for both genders. Also, dinner was the largest contributor of energy in both genders. Students ate more bread, cereals, and meat at dinner than during the other meals and snacks. Fruit was consumed more during snacks than at the other meals by all students. It was concluded that students need more nutritional information about healthy nutritional habits, adequate intake of nutrients, and ideal body weights.

Alcohol has as much effect on our lives as the different taste for foods that people have all of the world. Recently, the interest about drinking habits has increased with the rise in health problems for college students with poor health related behavior. The purpose of this study was to evaluate alcohol consumption, smoking and eating behavior of college students in the Kyungsan area. This survey was administered through questionnaires, and the subjects were 177 male and 189 female college students. The self-administered questionnaire was composed of questions concerning social-demographic factors, general characteristics, cigarette smoking, alcohol consumption and eating behavior. The data were analyzed by $\chi$$^2$-test and t-test. According to the survey results, almost of all of the survey subjects drank alcohol. The mean alcohol consumption level per day for male students (33.9${\pm}$29.7g) were significantly higher than for the female students (18.5${\pm}$16.5g), and more than 39.6% of the subjects drank alcohol 1-3 days a week. Alcohol consumption changed the students eating habits. Most students had dietary problems such as fast eating, skipping meal and spending too much money on fast food. The survey about eating behavior of the students showed the male students had more problems when compared with female students. Alcohol consumption levels and alcohol dependence showed a significant positive correlation with smoking cigarettes (r=0.386, p＜0.001). The correlation coefficient between alcohol consumption and eating behavior was negatively correlated with skipping meals (r=-0.121, p＜0.001). However, there were significant and positive correlations with overeating when students were depressed (r=0.130, p＜0.05), with eating meals when watching TV or videos (r=0.085) and with spending money on fast food(r=0.235, p＜0.235). The results indicate that health related behaviors of college students in the present study were fairly good. More attention should be given to college students and their habits of skipping meal, alcohol drinking and smoking, and the fairly good students can act as a model for correct dietary behavior so as to improve overall student health.
