The objective of this study was to investigate the effects of vegetarian (lacto-ovo vegetarian) and non-vegetarian diets on dietary habits, nutrient intake, and health status. The vegan subjects were 22 children. Among them, 54.5% of the subjects had a specific religion, 36.4% had been vegetarian since weaning, and 9.1% had become vegetarian to prevent obesity or atopy. The percentages of excessive eating by the vegetarian children were lower compared to the non-vegetarian children. The rates of intake of vegetables (42.2%) and fruits and fruit juice (55.9%) by the vegetarian children were higher compared to non-vegetarian subjects. Non-vegetarian children consumed more milk, dairy products, as well as meat, fish, eggs, soybean, and tofu than the vegetarian subjects. Vegetarian children ate more bread, potato, and fruits as snacks than non-vegetarian children. Furthermore, non-vegetarian children consumed more carbonated beverages and ice cream than the vegetarian subjects (p<0.05). Generally, the subjects' energy intake was lower than standard values, and vegetarian children's calcium intake was deficient. Non-vegetarian children's fiber intake was deficient, and they consumed fat, vitamin $B_2$, calcium, and cholesterol excessively (p<0.05). Nutrition tablet intake was higher among non-vegetarian children; however, the rate of fatigue among subjects was higher among vegetarian subjects than non-vegetarian subjects. Among the vegetarian subjects, 19.6% reported that they had a cold. Consequently, for the purpose of attaining balanced physical development and growth among children, an education program that emphasizes complete diets should be prepared.

This study described the status of snack intake and personality of middle school students, determined the differences in snack intake and personality according to gender and grade levels, and examined the effect of snack intake on personality. Data were collected from a self-reported survey from students of a middle school in Gwangju city and 717 questionnaires used for the analyses. The data were analyzed for frequency, percentage, mean, standard deviation, Cronbach's α, t-test, ANOVA, Duncan test, and multiple regression analysis using SPSS/PC 18.0 program. The results obtained were as follows. First, as for the snack intake frequency, '1~2 times per a day' had the largest number of responses(42.3%), followed by 'sometimes'(37.6%), '2~3 times per a day'(12.6%), 'never'(7.5%). As for the reason of snack intake, 'habitually'(27.3%) had the largest number of responses, followed by 'insufficient amount of meal'(21.0%), 'skipping meals'(13.6%), and 'stress relief'(8.2%). Mean score of agreeableness was the highest(3.64) among the personality components followed by Openness/intellect(3.42), Extraversion(3.36), Conscientiousness(3.15), and Emotional Stability(3.09) on the 5-point scale. Second, there were statistically significant differences in Emotional Stability depending on the gender. There were statistically significant differences in Extraversion, Agreeableness, and Openness/intellect by the grade level. Third, fruit intake frequency had statistically significant influence on Extraversion(β=.134). Intake frequency of bread(β=-.099), fruit(β=.142), ice cream(β=.092), and rice cake(β=.090) had statistically significant influence on Agreeableness. Intake frequency of bread(β=.105), drink(β=-.113), fruit(β=.113), and flour-based food(β=-.126) had statistically significant influence on Emotional Stability. Intake frequency of fruit(β=.106) and milk(β=.110) had statistically significant influence on Openness/intellect. Intake frequency of fruit had statistically positive influence on all the personality components. Intake frequency of rice cake had statistically positive influence on two personality components. Intake frequency of drinks had statistically negative influence on Emotional Stability. The outcomes indicate that snack intake affects the personality of adolescents.

To assess trans fatty acids (tFAs) intake of a girls' high school students in Pusan, dietary history and quantitative food frequency questionnaire (FFQ) were surveyed and analyzed with a total subjects of 274, 268 in summer and winter respectively. It was shown that 38.0% of subjects which was the highest percentage, had snack twice a day in frequency of snack intake. The most favorite snack of subjects was ice cream (46.4%), the preference for milk and dairy products was considerably high. 43.4% of subjects responded to once a month in frequency of dining out. They preferred grilled pork (39.1%), hamburger (36.9%), grilled beef (26.6%) in order. It was also appeared that they preferred fast food. In the case of eating bread, 8.0% of subjects ate bread and margarine, 7.1% butter. Generally, the subjects preferred margarine to butter. tFAs intake for each person per day was $4.24{\pm}0.18\;g$. There was significant difference in tFAs intake according to parents income (p<0.05), frequency of snack intake (p<0.001) and that of dining out (p<0.05). tFAs intake produced naturally (N-tFAs) was $0.86{\pm}0.00\;g$ which corresponded to 20.3% of total tFAs intake per day. tFAs intake produced artificially (H-tFAs) in the process of hardening oil was $3.38{\pm}0.14\;g$, equaled to 79.7% of total tFAs intake per day. There was significant difference between H-tFAs intake for each person per day (p=0.000)

This study was conducted to investigate causes for health problems among college women by analyzing factors related to their dietary habits, physical development, health habits, and blood parameters. The subjects were ages 20 to 24 years, lived in the Seoul area and were randomly selected during March, 2008 to August, 2009. The average height and weight of the overall subjects were $162.02{\pm}4.89\;cm$ and $53.96{\pm}7.00\;kg$, respectively. According to a 3-point assessment scale for the subjects' dietary habits, the average point value was 21.2. The percentage of subjects that ate breakfast daily was only 30.5%, and they omitted regular meals at least once a week. Approximately 83.5% of the subjects reported eating out often or frequently, and preferred Korean foods when they ate out. The subjects had interim meals (snacks) one or two times daily, and 40.4% of them preferred unbalanced meals. As their interim meals, among the 'good' group, ate breaded potatoes (39.3%), carbonated beverages, and ice cream (36.8%), whereas the 'poor' group, drank milk and ate dairy products (38.0%) as well as fast food and fried food (22.8%). Intakes of energy, fat, vitamins $B_2$ and $B_6$, niacin, folic acid, calcium, iron, zinc, and phosphorus were higher in the 'poor' group. The average hemoglobin level ($13.77{\pm}1.00\;g/dL$) among the subjects was within normal range; while 2.7% of subjects had hemoglobin levels under 11.1 g/dL (standard value) and were examined as anemic. The degree of interest in health was 24.5% higher among the subjects who had poor dietary habits. In contrast, among those who had good dietary habits, 49.6% reported they had no interest in regular exercise. The subjects reported that regular meals, nutrient intake, sufficient rest, and sleep as necessary to maintain health. The average amount of sleep obtained by the subjects was 6~8 hours. Among the 'poor' group, 36.2% reported that they exercised regularly, whereas 18.5% of the subjects in the 'good' group reported regular exercise (p<0.05). In conclusion, it appears necessary to provide nutrition education through teaching and to promote nutrition and health to college women so they can control their individual health status and create practicable dietary plans.

The purpose of this study was to compare the intake status of calcium, phosphorus, iron, and zinc of Korean adults residing in different regions. Subjects were recruited and divided into three groups according to the districts where they lived, which included rural (n=137), coastal (n=100), and urban district (n=117). Subjects were interviewed using a general questionnaire and 24-hour recall method for dietary intake. The average age of the subjects were 58.1 years for rural district, 57.7 years for coastal district, and 48.6 years for urban district. There was no significance in total food intake by regions. The food intakes from cereals, mushrooms, vegetables of rural district, that from fishes of coastal district, and those from sugars, milks, oils of urban area were the highest among three districts. The calcium, phosphorus, iron, and zinc intakes were $60.1\%,\;123.9\%,\;95.2\%,\;and\;73.1\%$ of RDAs, respectively. The calcium intakes as percentage of RDA in rural and coastal district were significantly (p<0.01) lower than that in urban district. A larger number of subjects from coastal or urban district ate under $75\%$ of zinc RDA compared to those from rural village. Major sources of dietary calcium in total subjects were anchovy, kimchi, milk, soybean curd, rice, ice cream, sea mustard, yogurt, loach, and welsh onion. Rice supplied $15.5\%$ for phosphorus, $22.1\%$ for iron, and $35.9\%$ for zinc of total intake. Except for rice, major sources of dietary zinc were pork, beef, small red bean, dog meat, chicken, jacopever, soybean curd, glutinous millet, and kimchi. In conclusion, the food and mineral intakes of adults differed according to the regions in which they resided. The food and nutrient intakes of coastal district were not satisfactory, and calcium and zinc intakes of three regions did not meet RDAs. Therefore, it is required unique and discriminatory nutritional education with each region for increasing intakes of calcium and zinc.
