This study was to investigate dietary life and eating-out style related to breakfast frequency of male students in culinary college. This survey was conducted using questionnaires for 110 male students at college in Hongseung. Mean height and body weight of those we investigated was 174 cm and 70.5 kg. The one to two times per week breakfast eating group was 34.55%, which is exceedingly numerous; none per week breakfast eating group was 30%; three to tow times per week breakfast eating group was 15.45%; everyday breakfast eating group was only 9.09%. The breakfast frequency was very low, and the not-eating breakfast problem is serious to think of in male college students. Mean weight, body fat and body mass index(BMI) of the everyday breakfast eating group was lower than the other group even it was not significant. The self-boarding house or dormitory living condition group was not eating breakfast was significant. So a correct dietary lift and eating habit should be taught further for male college students. The smoking group was a significant low frequency of breakfast eating, as well as the lower frequency of breakfast, or worse recognition of self health condition. Higher frequency of breakfast showed more contentment of self body weight. Cooked rice was significantly the most preferable for breakfast. The lower breakfast frequency tended to eat breads or cereals. The lower frequency of breakfast, self recognition of eating rate as speedier was significant, and tended to have a higher frequency of eating-out because of being annoyed by cooking. The lower breakfast frequency ate out more. Twenty five percent of the everyday breakfast eating group ate out because of a special day, and thirty five percent of the not eating breakfast group did so because of being annoyed by cooking. Their mean dietary evaluation grade was under the normal grade, which means that culinary college male students' dietary lives were poor. The lower frequency of breakfast and lower grade of food life evaluation, indicates the importance of nutritional breakfasts education should be improved for male culinary college students also.

In order to investigate the effects of frequent eating-out and breakfast skipping of working men on body mass index and nutrients intake status, working male adults aged 20 or over were selected (n = 1883) from the data of 2001 Korea national health and nutrition survey. The subjects were divided into 4 groups according to the eating-out frequency(high: once or more daily, low: less than once daily) and breakfast eating or not. Four groups were high eating-out with breakfast eating (n = 609), high eating-out with breakfast skipping (n = 192), low eating-out with breakfast eating (n = 877), and low eating-out with breakfast skipping (n = 205). High eating-out group showed higher body mass index (BMI) than low eating-out group, but the difference of BMI was disappeared when adjusted with age, residence region and family income. However high eating-out group in case of breakfast eating, compared with the low eating-out, showed higher intakes or densities of energy, fat, fat-energy% and higher ratio of energy-fat overintake, and also showed higher mean nutritional adequacy ratio and lower ratio of nutrients intake deficiency. Calcium, iron, vitamin A and C intakes were not affected by eating-out frequency, but were lowered by breakfast skipping. Breakfast skipping also decreased intake frequency of unprocessed cereals and increased those of ramyon and carbonated and alcoholic beverages. From the results frequent eating-out with breakfast eating caused increased intakes of energy and fat, but did not cause BMI increase. Breakfast skipping, but not eating-out, had negative influences on mineral and vitamin intakes. Accordingly good eating-out as well as breakfast eating should be exceedingly emphasized at nutrition education for the working males.

In this study, we have analyzed the 2015 KNHANES VI to understand the nutritional and health status of Korean middle-age adults from the perspective of frequency of eating breakfast. Those that eat breakfast five to seven times a week were 76.3 percent (male) and 72.7 percent (female). Frequency of eating lunch and dinner, and eating out was significantly higher among male subjects. The higher the frequency of eating breakfast, the higher the frequency of eating lunch, dinner and eating out. Female subjects that ate breakfast five to seven times a week had lower height and weight compared with other groups, but there was no significant difference of BMI and waist circumference among the four groups. Adults that eat breakfast five to seven times a week had consumed more carbohydrates, dietary fiber, phosphorus, potassium and vitamin C regardless of gender, which validates the nutritional benefits of eating meals regularly. Male adults that ate breakfast five to seven times a week revealed lower levels of diastolic blood pressure and LDL-cholesterol compared with other groups, which validates eating breakfast regularly was beneficial to their health. In conclusion, it is necessary to eat regular meals daily relative to the nutritional status and health of Korean middle-age adults.

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.

BACKGROUND/OBJECTIVES: Skipping breakfast is prevalent in young adult women. This study examined the psychosocial factors and eating behaviors according to the breakfast frequency among female university students. SUBJECTS/METHODS: The subjects were female university students in Seoul, South Korea. A survey was done, and the data from 291 students were analyzed. The subjects were categorized into a high breakfast group (HBG) and low breakfast group (LBG). Analysis of covariance and multiple linear regression were mainly used in data analysis. RESULTS: The subjects had breakfast 3.6 days/week on average. The HBG (47.4%) and the LBG (52.6%) differed significantly in breakfast status, including place, people eating together, breakfast menu, and breakfast preparers (P < 0.001). The HBG agreed more strongly with the advantages of breakfast than the LBG (P < 0.001). The disadvantages/barriers of breakfast were stronger in the LBG (P < 0.001). The HBG felt more confidence in having breakfast (P < 0.001) and confidence in general eating behaviors (P < 0.05). The two groups also differed in the subjective norms from parents/professionals (P < 0.001) and siblings/friends (P < 0.01). The HBG showed desirable eating behaviors more frequently (P < 0.001) and undesirable eating behaviors less frequently (P < 0.001). Multiple regression showed that the following were significantly related to the breakfast frequency, explaining 57.3% of the variance: self-efficacy regarding having breakfast (P < 0.001), perceived barriers of breakfast (no appetite/habit/indigestion, P < 0.001), desirable and undesirable eating behaviors (P < 0.01), subjective norms from parents/professionals (P < 0.05), and perceived barriers due to lack of time/preparation difficulties (P < 0.05). CONCLUSIONS: Psychosocial factors and eating behaviors were significantly related to the breakfast frequency. Nutrition education might include strategies to increase self-efficacy for breakfast, modify the beliefs, particularly the disadvantages/barriers of breakfast, adopt desirable eating behaviors, and elicit support from significant others.

The purpose of this study was to examine the effect of eating with family or alone on the self-rated mental or physical health and then work out strategies of making people recognize the importance of eating with family and its practice. Study subjects were 610 primary school 5th- and 6th-grade students in Daejeon Area. A questionnaire survey was carried out. 57.9% of students had working mothers. The frequency of meal in a day was $2.90{\pm}0.42$ and this frequency was lower in students who had working mothers (p < 0.05). The frequency of skipping breakfast (times/week) was $1.02{\pm}1.77$. The frequencies of eating alone (times/week) were $1.04{\pm}1.65$ for breakfast and $0.97{\pm}1.52$ for dinner. Also, the frequency of eating alone for dinner was higher in students who had working mothers (p < 0.001). When the frequency of eating alone for breakfast or dinner was higher, the frequencies of skipping breakfast and dinner were also higher (for all, p <0.01). When the frequency of eating alone for breakfast or dinner was higher, the self-rated positive mental health were lower (p < 0.05 and p < 0.01 respectively) and the self-rated negative mental health (for dinner, p < 0.05) and the self-rated negative physical health was higher (p < 0.05 and p < 0.01 respectively), thus presenting negative health. The frequencies of eating with family (times/week) were $3.37{\pm}2.50$ for breakfast and $4.14{\pm}2.19$ for dinner. Also, the frequency of eating with family for dinner was lower in students who had working mothers (p < 0.01). When the frequency of eating with family for breakfast was higher, the frequency of skipping breakfast was lower (p < 0.01). When the frequency of eating with family for dinner was higher, the frequency of skipping dinner was lower (p <0.01). In addition, when the frequency of eating with family for breakfast or dinner was higher, the self-rated positive mental health were higher (for both, p <0.01) and the self-rated negative mental health was lower (for breakfast, p < 0.01) and self-rated negative physical health were lower (for both, p <0.01), thus presenting positive health. Therefore, in order to maintain positive health, it is necessary to recognize the importance of eating with family at home and educate people to carry out a systematic and continuous dietary life, thus increasing eating with family and reducing eating alone and skipping a meal.

The purpose of this study was to determine the factors related to eating behavior of breakfast and dietary life score in elementary, middle, and high school students. This study was conducted by administering questionnaires, and data were analyzed by the SPSS program. The subjects were divided into three groups according to school group (elementary, middle, and high school). The subjects consisted of 1,879 students (male 973, female 906) from 11 schools in Kyungpook. The distribution of subjects was as follows: elementary school children 682, middle school students 702, and high school students 495. The results are summarized as follows. Dietary life score was 72.64 for elementary school students, 64.77 for middle school students, and 62.67 for high school students. Frequency of eating breakfast and reasons for skipping breakfast were significantly different according to school group (P<0.001, P<0.01, respectively). The main reason for skipping breakfast was 'habitual skip' for elementary and middle school students (54.8%, 46.7%) and 'getting up too late' in high school students (55.4%). There were no significant association between frequency of eating breakfast and BMI. However, there were significant differences in school performance and sleeping hours according to frequency of eating breakfast (P<0.001, P<0.01, respectively). Dietary life score was significantly different according to frequency of eating breakfast (P<0.001). These results stress the need for intervention programs aimed at decreasing the frequency of skipping breakfast in children and students at school. Further, those who prepares meals for children must increase their concern about preparing breakfast.

The purpose of this study was to evaluate the dietary behavior, nutrient and food intake status and dietary quality based on nutrient and food group intake and Diet Quality Index-International (DQI-I) according to breakfast eating status in female university students. The survey was conducted using questionnaires and 3-day dietary records for 181 female university students residing in Seoul, Gyunggi, and Gangwon. The subjects were divided into two groups by frequency of breakfast eating: skipping breakfast (frequency of eating breakfast under 4 times/week, n=69) and eating breakfast (frequency of eating breakfast over five times/week, n=112). The skipping-breakfast group was significantly lower in its frequency of having lunch than that of the eating-breakfast group. There was no significant difference of energy intake between the two groups; however, the intake of carbohydrate, fiber, folate, vitamin C, vitamin E, Ca and Fe in the skipping-breakfast group was significantly lower than those in the eating-breakfast group. There was no significant difference in Korean's Dietary Diversity Score (KDDS) between the skipping-breakfast group ($4.65{\pm}0.56$) and eating-breakfast group ($4.73{\pm}0.50$). The average DQI-I of the skippingbreakfast group ($56.96{\pm}9.04$) was significantly lower than that of the eating-breakfast group ($61.32{\pm}7.99$). In conclusion, female university students with a high frequency of skipping breakfast may have a lower diet quality and DQI-I score. Therefore, in support of proper dietary management, it is necessary to promote and support breakfast eating.

The objective of this study was to examine relationships between breakfast skipping and ecological factors related to eating practice. Participants were 537 children (male: 274, female: 263) from two elementary schools in Kyunggi-do (School A) and Seoul (School B). Analysis included cross-tabulation of demographics, factors related to eating practice and weight status, frequency of breakfast skipping and types of breakfast and the number of foods at breakfast by schools. Logistic regression were conducted to identify the factors associated with breakfast skipping. Children in school B showed higher socioeconomic status by living environment and the type of fathers' job than those in school A. Eighty six percent of children in school B and 75% in school A ate breakfast 5 times and more per week. School and father's occupation differences correlated with the frequency of breakfast, but not mother's employ status was not. After controlling school. type of father's job, mother's employ status, eating breakfast 5 times and more was associated with eating with other family members, feeling hungry before breakfast, normal weight status, eating Korean traditional meal type and number of food eaten at breakfast. The results stress the need for intervention programs aimed at decreased skipping breakfast among elementary school children. While programs need to reach all children skipping breakfast, approaches need to be suitable to in particular those from low socioeconomic backgrounds.

The purpose of this study was to examine a questionnaire survey on nutrition knowledge, dietary behaviors and the evaluation of nutrient intakes in regard to frequency of eating breakfast for a total 383 high school female students in Chuncheon area. The subjects were categorized into 3 groups according to frequency of breakfast : eating breakfast group (6-7 times/week, 49.1%), sometimes eating breakfast group (3-5 times/week, 22.2%), skipping breakfast group (${\leq}2$ times/week, 28.7%). The eating breakfast group and sometimes eating breakfast group have better grades on nutrition knowledge related to breakfast than the skipping breakfast group. The skipping breakfast group have a smattering of nutrition knowledge like, the importance of having breakfast, maintaining calories, and the brain's energy resource. There was a strong correlation between the frequency of breakfast and dietary behavior grades. The students who skip breakfast have irregular eating habits and their eating speed was improper. Also, their frequency of taking in cereals, proteins, fruits, vegetables, and dairy products was poor. The results of the survey on nutrition intake show that while, students who eat breakfast are consuming only folate, calcium and iron at a less than recommend intake, the students who skip breakfast are consuming vitamin $B_2$, niacin, vitamin C, vitamin $B_1$ as well as folate, calcium, and also iron at a less than recommended intake. Based on these results, it is necessary to develop an awareness program that emphasizes the importance of breakfast and accurate nutrition knowledge for students.
