This study was carried out to identify factors related to breakfasts in elementary, middle and high school students. This study was surveyed by questionnaires and data was analyzed by SPSS program. Exploratory analysis was conducted according to three school student groups (elementary children, middle school students, and high school students). The subjects were 1,886 school students (female 893, male 959) of 51 schools in the nationwide region. The distribution of subjects was elementary school children 544, middle school students 661 and high school students 681. The results are summarized as follows. Only sixty percent of the subjects had breakfast regularly. About one fourth of the subjects had the habit of skipping breakfast or eating it 2$\sim$3 times per week. Frequency of having breakfast and reasions of skipping breakfast were significantly different according to school student groups (p < 0.001 respectively). The rate of skipping breakfast was $14.4\%$ in elementary school, $16.1\%$ in middle school, and $25.0\%$ in high school. The main reason for skipping breakfast was 'not delicious or poor appetite' in elementary school ($42.5\%$), but 'busy' in middle ($50.2\%$) and high school ($61.1\%$). There was no significant difference in frequency of having breakfast according to living areas (rural and urban). There were not significant differences between frequency of having breakfast and BMI and degree of satisfaction on body weight. But there were significant difference in frequency of having breakfast according to economical status (p < 0.05). There were significant differences in degree of school performance according to frequency of having breakfast (p < 0.001) There was significant relationship between the time of attending school and the frequency of having breakfast. But there were significant relationships between frequency of having breakfast and time of rising. These findings suggested that the time of rising was controlled by having enough time that students eat breakfast. And mother (or person who prepares meals) must have more concerns about preparing breakfast for children and students.

The purpose of this study was to investigate the effect of Monacolin-inoculated rice embryo on the body fat and serum lipid profiles in 61 obese elementary school students. The subjects divided into two groups 31 obese children had the experimental diet (rice embryo inoculated Monacolin) and 30 obese children had the control diet three times a day after meals. The mean age, height, weight, and BMI of 61 subjects were $10.5\pm0.5$ years, $143.6\pm6.8cm,\;55.0\pm8.9kg,\;and\;26.1 \pm3.9$, respectively. The changes of body fat mass (kg) in experimental group and control group after 6 weeks were -0.60kg and -0.03kg, respectively. The changes of body fat $(\%)$ in experimental group and control group after 6weeks were $-1.44\%\;and\;-0.25\%$, respectively. These changes of body fat in experimental group were significantly higher than in control group (p<0.05). The change of total-cholesterol in experimental group and control group during 6weeks were -17.52mg/dL and -1.70mg/dL, respectively. The change of LDL-cholesterol in experimental group and control group during 6 weeks were -17.06mg/dL and - 2.80mg/dL, respectively. The change of triglyceride in experimental group and control group after 6 weeks were -9.58mg/dL and 11.67mg/dL. Total-cholesterol, LDL- cholesterol and triglyceride of experimental group after 6 weeks significantly decreased compared to control group (p<0.05). After experimental diet (6 weeks), total-cholesterol was negatively correlated with body water contents, soft lean mass and fat free mass (p<0.05). Triglyceride showed a significantly positive correlation with body weight and body fat mass, however, it was negatively correlated with fat free mass (p<0.05). HDL-cholesterol showed a significantly positive correlation with fat free mass (p<0.05). These results show that Monacolin-inoculated rice embryo is effective in decreasing body fat and blood lipid in obese children.

This survey was carried out to obtain the information concerning nutritional status, including factors of food habits and nutrient intake of the long-lived elderly men and women living in Ganghwa-gun. In order to assess the quality of dietary intake among the elderly, a survey was conducted during December 2003 of 103 subjects who were over 85 years of age. Dietary nutrient intake data were obtained through the 24 hr recall method. Chi-square test and t-test were the main data analysis method. Their dietary habits such as three meals a day and a regular meal time have shown that they have generally good eating habits. Average daily calorie intake ($\%$ RDA) was 1233.2 kcal ($68.8\%$) for male and 1215.8 kcal ($75.8\%$) for female which were lower than the Recommended Dietary Allowances (RDA) for Koreans. Energy intake of females got closer to RDA than that of male. Protein intake was 49.3 g for male and 46.9 g for female (which was $82.3\%$ RDA for male and $85.1\%$ RDA for female) for elderly person, the proportion of animal protein to total protein intake were $45.2\%$ for male and $39.0\%$ for female. Average CPF ratio of energy intake for both male and female were 68.7 : 16.1 : 15.2 and 69.6 : 15.4 : 15.0. SFA : MUFA : PUFA ratio of the subject was 0.78 : 1.03 : 1.00 for male and 0.64 : 0.92 : 1.00 for female. Calcium intakes for both males and females were 321.3 mg and 377.2 mg. Vitamin A was the nutrient found to be least sufficient. Mean daily intakes of most of the vitamins and minerals for both males and females were lower than RDA except vitamin C and Zn for female, especially $\%$ RDAs of vitamin A, Ca for male and vitamin A for females were less than $50\%$ of RDA. In conclusion, long-lived elderly in Ganghwa areas did not consume enough nutrients quantitatively as well as qualitatively, especially Ca, Fe, vitamin A, vitamin $B_2$ and vitamin E. These results suggest that nutritional guidelines for older Koreans should focus on the maintenance of adequate energy intake. In addition, selection of foods with high protein and calcium, such as dairy food, should be emphasized, particularly in the long-lived elderly.

This study was conducted to understand the conceptual definition and characteristics of health inequality. To accomplish this, we analyzed data collected from 14 participants as well as from available literature regarding health inequality using the hybrid model introduced by Schwartz-Barcott and Kim. We categorized health inequality into nine attributes in three dimensions. These dimensions included "target", "precede", and "result," corresponding to the target, cause and consequence of health inequality, respectively. Specifically, we define health inequality as individuals, families, communities, socio-economic, or geographically distinct demographic groups that are treated unfairly and result in several problems such as loss of quality of life, reduction of survival rate, or aggravation of a disease due to (i) poor treatment by a hospital (ii) irregular meals, (iii) desperate need for work (for money), (iv) expensive medical care costs, (v) qualitative differences in medical care by regional groups (vi) the lack of knowledge regarding disease (vii) and inadequate health care because of lack of time. As a result of this unfair treatment, human rights violation occurs. The major contribution from this paper is that we provide a guideline for establishing strategies to reduce health inequality by identifying the concept of health inequality. Based on this study, we recommend development of an educational program to reduce health inequalities.

This study was conducted to investigate the effects of residence types ((1) parent house, (2) dormitory or boarding home, (3) boarding home w/o food) on the dietary habits and health status of college women (20-23 y). Overall, 46.1% of college women reported that they were economically middle class and spent 200,000-390,000 won. Additionally, 17.4% of college women considered themselves healthy, while 33.8% reported that they were not healthy. Furthermore, 32.0% of college women had experience to control their weight and 39.8% reported that they exercised to control their weight. There were no significant differences in the height and weight of the subjects according to residential type, but the amount of skeletal muscles mass ($21.0\;{\pm}\;2.6\;kg$) of the subjects that lived in dormitory or boarding home was significantly higher (p < 0.05) than that of women who lived at home. Additionally, 30.8% of students that lived in private residences, 25.0% of students that dwelled in dormitory or boarding homes and 27.7% of students that boarding home w/o food had three regular meals every day (p < 0.05). It has been reported that 18.3% of college students eat processed and instant foods due to their convenience. In the present study, intakes of energy, protein, fat, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, vitamin C, vitamin E and folic acid for the subjects who lived in dormitory or boarding homes was significantly higher than those of students who lived in private residences (p < 0.05). Additionally, intakes of iron, calcium, and zinc were lower in the subjects that boarding home w/o food (p < 0.05). Finally, the blood glucose level was $84.7\;{\pm}\;13.0\;mg/dL$, and differed significantly by residential types (p < 0.05); however, the average glucose levels of all subjects were within the normal range (90-110 mg/dL).

The purpose of this study was to investigate the relationship between oral health behaviors and the results of the oral dysentery test for dental hygienists and students at Gyeonggi - do and Chungcheongnam - do. Self - filling questionnaires and oral diseases. The following conclusions were obtained. The most common toothbrushing frequency was three times a day (60.2%), and the most dominant frequency of eating between meals was once or less(49.7%). The most common snack that they had was stickiness-free sweetened food(66.5%), and the type of beverage that they had the most was sweetened beverages(49.7%). The average stimulated saliva flow rate was 9.41ml, and they got a mean of 9.52 in the buffering capacity of saliva. The average glucose clearance time was a mean of 12.02. When they took a streptococcus mutans colony count test, 80.1 percent belonged to the low-risk group(<$10^5$), and 82.6 percent belonged to the low-risk group(<$10^5$) when a lactobacillus test was conducted. There was a positive correlation between the irritant saliva fraction and the non-irritating saliva and saliva buffering ability. In the fluoride application experience, the glucose retention time was 10.66 minutes and the fluoride application experience was 13.33 minutes. (P = .008). The importance of oral health, which is directly linked to general health, should be emphasized in order to improve the quality of life as well as the life expectancy. For oral health, which is directly linked to systemic health, it is necessary to provide opportunities for oral health education that can be easily accessed by the public, and to continuously develop and provide oral health care programs for a lifetime.

This study empirically examined the actual level of elementary school children's knowledge of nutrition and the extent of current nutrition education for the children through the use of textbooks. Two or three classes were sampled from each of six schools, respectively, in Gangneung; of the 562 questionnaires that were distributed, 537 were returned and used for analysis. Respondents were all sixth-graders, on average boys and girls were 153.02$\pm$8.19㎝ and 152.79$\pm$7.15㎝ in height and 45.27$\pm$10.32㎏ and 43.33$\pm$7.46㎏ in weight, respectively, which was consistent with others' research. Most children had two siblings and a working mother, considered that they were well off, and their mother prepared meals. Children regularly had breakfast and dinner, although more children had dinner than breakfast. As a whole, their knowledge of the main nutrients contained in foods was lower than their general knowledge of nutrition. There were significant differences in knowledge of the main nutrients contained in foods, with girls showing more knowledge than boys (p<0.01). Most of them learned about nutrition at school, followed by home. At school, Practical Technology classes taught them the most about nutrition. Although Physical Education classes were expected to teach about nutrition in a quantitative way, they accounted for just 4.7% of the overall knowledge. As for the children's understanding of nutrition education through use of a textbook at school, just 19% of the students gained a very good understanding. As for interest in nutrition education at school, 22.2% of the students had no interest, while girls were more likely to have their interest in nutrition education at school affected by knowledge of nutrition than boys. For both boys and girls, the most desired method of education was cooking practice. More research across subjects is necessary so that nutrition education concentrated on the curriculum for fifth-graders can be provided by stages from the lower grades. Since cooking practice or games were preferred, it is necessary to develop nutrition education methods to incite active interest rather than passive education.
