School foodservices serve vegetarian meals to shape healthy eating habits and create environmental awareness among students. The purpose of this study was to evaluate the nutritional content of vegetarian menus of an elementary school foodservice. We examined 334 vegetarian and 545 non-vegetarian menus at elementary schools in the Chungnam area and compared their food composition and nutrient content. The average number of dishes per vegetarian menu was 7.0, which was significantly lower than the 7.3 items per non-vegetarian menu. The number of staple and dessert dishes on the vegetarian menus was significantly higher than that of non-vegetarian menus. Contrarily, the non-vegetarian menus had a higher number of broths and side dishes than vegetarian menus. Menus comprising grains, meats·fishes·eggs, vegetables·beans, fruits, and dairy products constituted 39.2% of vegetarian and 50.1% of non-vegetarian menus. The dietary diversity score was 4.3 for the vegetarian menu and this was significantly lower than 4.5 for the non-vegetarian menus. In terms of nutrient content and the index of nutritional quality, the vegetarian menus had significantly higher levels of vitamin A and calcium than the non-vegetarian menus. However, the protein and vitamin B₁ levels were lower in the vegetarian menus. Our results suggest a need to develop balanced vegetarian menus and expand education to improve awareness, acceptance, and consumption of vegetables among school-age children.

The purpose of this study is to investigate the importance of well-being related to lifestyle choices such as food habits, food choices, life pattern, etc. The survey was conducted among college students using a questionnaire and a 5-point Likert score in Seoul City and Kyunggido Province during September 2005. The responses of 968 college students were analyzed by the SPSS program. The results were as follows. Most of the subjects were female(76.2%), and lived with their parents (85.6%). The average score of 'food habits', 'choosing food materials', 'purchasing' and 'life pattern' were $2.71{\pm}1.22,\;2.86{\pm}1.28,\;2.41{\pm}1.21,\;and\;2.97{\pm}1.31$ respectively in males and $3.01{\pm}1.20,\;3.00{\pm}1.32,\;2.55{\pm}1.20,and\;2.68{\pm}1.40$ in females, respectively. In regard to 'food habits', the scores were significantly affected by gender(p<0.001), smoking(p<0.05), alcohol consumption(p<0.05), exercise(p<0.001), weight satisfaction(p<0.001), method of weight control(p<0.001), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001), and whether the individual tried a well-being item(p<0.001). In regarding to 'choosing food materials' the scores were significantly affected by gender(p<0.001), smoking(p<0.05), exercise(p<0.001), weight satisfaction(p<0.05), method of weight control(p<0.05), use of nutritional supplement(p<0.05), attempts at weight control(p<0.001), regularity of breakfast(p<0.001), level of interest in well-being(p<0.001) ), and whether the individual tried a well-being item(p<0.001). Out of the factors affecting 'purchasing', the association with BMI was remarkable. Students who were overweight, obese or underweight showed higher average scores than students of normal weight. The primary concerns and trial of well-being of college students were food and exercise. Therefore, the purchase of well-being goods is related to their weight control in college students. In regard to 'life pattern' the scores were significantly affected by exercise(p<0.01), use of computer(p<0.001), BMI(p<0.001), weight control(p<0.001), use of nutritional supplement(p<0.05), regularity of breakfast(p<0.001), level of interest in wellbeing(p<0.001), whether the individual tried a well-being item(p<0.001), and having taken lecture on well-being(p<0.05). Therefore nutrition education is needed for healthy eating habits of college students and it is necessary to develop a series of lectures to teach them about diet and exercise programs.

The purposes of the study were to identify knowledge and skill levels required for effective nutrition teachers and to compare perceived need and dietitians' self-evaluation of the knowledge and skills. A total of 60 knowledge statements and 70 skill statements associated with 11 job functional areas were specified through a literature review and expert panel reviews. A total of 457 dietitians working at school foodservices in Seoul and Gyeonggi province were surveyed using a self-administrated questionnaire and 148 responses were returned. Excluding responses with significant missing data, 142 responses were used for data analysis. In terms of knowledge, 'sanitation, food safety and employee safety(4.60)' category received the highest perceived need score, followed by 'nutrition education(4.56)' and 'nutrition counseling(4.45).' The knowledge category that received the highest self-evaluation was 'nutrition and menu management(3.66)' while the category that received the lowest self-evaluation was 'teaching practices(2.83).' In terms of skills, the highest perceived need was associated with 'nutrition education(4.49)', followed by 'sanitation, food safety and employee safety(4.46)' and 'nutrition counseling(4.39).' The dietitians rated their skills related to 'sanitation, food safety and employee safety(3.67)' the highest but their skills related to 'teaching practices(2.84)' the lowest. The dietitians' self-evaluated knowledge and skill scores were significantly lower than their perceived need of the knowledge and skills in all job functional areas(p<0.001). A quadratic analysis based on the requirement and self-evaluation of the knowledge and skills revealed that priorities of the education programs targeting school nutrition teachers or students preparing to be a nutrition teacher should be placed on improving knowledge and skills related to nutrition education, nutrition counseling, teaching practices, sanitation and employee safety, and nutrition and menu management. Educational programs for nutrition teachers should be designed to decrease the gaps between the need and self-evaluation of the knowledge and skills for effective nutrition teachers. The findings of the study can be used to develop education materials for nutrition teachers. The knowledge and skills identified in the study should be updated and revised regularly to reflect changes in regulations and current practices in school foodservice programs.

This study aimed to investigate the relationship between the nutrition quotient and the dietary intake of adolescents. A total of 393 adolescents were surveyed to evaluate their Nutrition Quotient for Korean Adolescents (NQ-A) scores and dietary intake. The average age of the survey subjects was 15 years and the average NQ-A score of the subjects was 49.11±13.35. There was no significant difference in the NQ-A scores according to gender and age. The average dietary diversity score was 3.77±0.85, and it was significantly higher in boys than in girls (p< .05) with the scores of 12-14-year-old students being significantly higher than those aged 15-18 years (p< .01). The results of comparing the percentage of recommended intake or adequate intake and the mean adequacy ratio (MAR) according to the NQ-A grade, showed that the 'High' grade had a significantly higher intake percentage of vitamin B1, B12, folate, phosphorus, iron and a significantly higher MAR (p< .05). From a long-term perspective, efforts to improve dietary habits are deemed necessary to meet an individual's nutritional requirements. Adolescents themselves should develop proper eating behaviors and acquire suitable dietary management skills to enhance their nutritional status, ultimately contributing to an improvement in their quality of life.

The principal objective of this study was to evaluate elementary students' awareness of the importance of hand washing, as well as their hand-washing behavior. The data was collected by self-reported questionnaire from 697 students in elementary schools with serving food in a classroom in Busan. Their hand-washing frequency was high, at '3~4 times per day (37.0%)'. 51.0% of the respondents did not wash their hands that often because they were 'not accustomed' to washing their hands, and 35.9% of respondents regarded washing their hands as 'annoying'. The most frequently reported hand washing agent was 'soap and water (71.4%)'. Approximately 95~98% of the respondents always washed their hands after using the bathroom, 87.9% of them washed their hands before eating food, and 86.7% of them washed their hands upon returning home. However, 27.3%, 34.1% and 65.9% of the respondents did not wash their hands after handling money, after eating, and after coughing or sneezing, respectively. Significant factors related to increased hand-washing frequency were gender (p<0.001) and the period of attendance at kindergarten (p<0.05). The mean scores of importance and performance of hand washing were significantly higher for girls than for boys. The group with higher rate (over 4.5/5.0) for the importance of sanitary hand-washing behavior showed significantly higher scores in hand-washing behavior before serving food and before eating than those of the lower rated group (below 4.0/5.0). This study shows that sanitation education is required not only for food handlers but also for students in school foodservices.
