Perceptions and concerns of parents about elementary school lunch service were investigated by questionnaires in March, 1998. Five hundred and ten parents were selected randomly from schools in the city area, the rural area or the islands in Incheon Metropolitan city. 95% of parents preferred the school lunch service because nutritious food was available to the children regardless of family income or mother's occupation. Meal cost per capita was in the range of 1,000 and 1,200 won, which satisfied most parents (74%). Moreover, many parents (68.8%) were willing to pay extra money to support the school lunch program and they actually had such experiences (82.4%). More than 90% of the respondents wanted to be adviced about the menu. Subjects chose nutrition and sanitation(25%), taste (18%), and meal size (16%) as aspects of improvement in school lunches. Parents wanted to participate in serving foods, cooking, and washing dishes once (23%) or twice (31%) a year and they considered this as a good opportunity to join the school activities. 98% of parents showed very positive responses to the nutritional education provided by the school dietitian.

As the school lunch program is expanding to middle and high schools in Korea, a survey has been conducted to provide informations of the types and menus which are most favored on 190 middle and high school students in Metropolitan area. The sources/menus of foods relating to their lunches were proportionally ranked as: school food services (54.2%): individual lunch-box from home(37.4%); take-out lunch box(3.7%): school cafeterias(1.6%): and commercial restaurant, undefined, and skip a meal(1.1%). For the present practices for lunch, 52.1 and 47.9% of the students responded satisfaction on its sources and menus, respectively. A meal valued less than 2,000 won was paid by 54.9% of the respondents. In the meantime, 33.7 and 55.4% of the students were unsatisfied with lunch box from home and school cafeteria of the present lunch practices, respectively. The reasons against their satisfactions were enumerated as their preferences for take-out lunch box(22.2%), school cafeteria(21.0%), outside restaurant(17.3%), individual lunch-box from home(16.1%), school cafeterias(8.6%), and undefined (14.8%). For the individual lunch-box from home, two major obstacles, i.e., it is neither warm to eat, nor diverse/properly-sized in side dishes, were reasons for dissatisfaction of the students. The school lunch programs were blamed for its poor taste and lacks of variety and volume of the side dish which is mostly composed of kimchi, seasoned vegetables, and bulgogi. The most popular side dishes were pork- or fish cutlets, hams, and sausages while food with carrots, garlics or red peppers, vegetables like pumpkins, lotus roots, and seasoned vegetables were mostly disliked. It was concluded that the school lunch programs for middle- and high school students could be settled down by preparing with well-nourished food items that suits students' taste best and be served at right temperature.

This study was designed to assess the iron nutritional status and growth development of children provided with and without the national school -lunch program(NLSP). The subjects consisted of 590 elementary school children (313 boys, 277 girls) in the 2nd, 4th and 6th grades provided with (n=390) and without (n=200) NSLP. anthropometric measurements were taken for body weight, height, triceps skinfold thickness and body fat percentage. Nutrient intakes were assessed by a modified 24 -hour recall method. Fastinig blood samples were obtained and analyzed for hemoglobin concentration, hematocrit, serum iron and total iron binding capacity. The results obtained are summarized as follows. No significant differences between children provided with and without NSLP were found in height and body weight, but triceps skinfold thickness and body fat(%) were significantly higher in children without NSLP than in those with NSLP. There was no significant difference in hemoglobin concentration and hematocrit between children provided with and without NSLP. However, serum iron concentration and transferrin saturation were higher in the children provided with NSLP(81.9$\mu\textrm{g}$/dl and 22.8%) than in the children without NSLP(73.1$\mu\textrm{g}$/dl and 20.9%). When comparing iron and vitamin C intakes , iron intake was significantly higher in children provided with school-lunch, but vitamin C intake was significantly higher in children provided without school-lunch. Percentages of iron -deficient anemia in underweight, normal and obese children when judged by total iron binding capacity were 14.9%, 12.5% and 25.8% respectively.

Teacher's satisfaction with school lunch programs run by foodservice(FS) management types were surveyed with questionnaire at 5 middle and 4 elementary schools. The 88 middle and 104 elementary school teachers who participated and schools' FS management were of 5 types : self/conventional, contracted/conventional, contracted/commissary and contracted/dosirak delivery. Most teachers knew correctly their schools' present FS management types and thoroughly understood the main reasons for needing school lunch program with proper nutrition, better taste and balanced diets in addition to the first reason its less work than preparing homelunches. Teacher's satisfactions with their present school FS were high in self/conventional and contracted/conventional and was very low in contracted/commissary and contracted/ dosirak Taste, hygiene, nutrition and dining facilities in turn were pointed out to be improved : firstly hygiene in the self and firstly taste in the contracted. Particularly dining-rooms were found to have narrow space, uncomfortable chairs and tables, unclean, and having unpleasant smells. Teachers observed that the overall students' food habits such as eating more various foods and better table manners through that school lunch programs, particularly the self-managed types were improved. Conclusively most teachers emphasized school lunch programs to be continued and preferred self-managed types and contracted/conventional types as the second best in having less work to manage, better, taste, nutrition and hygiene, less cost and better nutrition education in turn. And they thought school founders should handle the finances needed to newly establish or repair the school FD facilities, otherwise provided with the partial aid of student's parents.

We evaluated the nutritional status of 116 Songmyun middle school students. The means of height and weight were similar to the standards published by the Ministry of Education(1991). The height of 79% of the subjects was in the normal range, and the height for 11% was below the normal range. While 27% of the subjects were underweight, 18% and 8% were overweight and obese, respectively. The percentage of anemia was 29%, and the mean urinary urea nitrogen to creatinine ratio was 8$\pm$4. Total daily energy and nutrient intake was 48-103% of RDAs, and especially calcium and iron intake was very low. Carbohydrate, protein and fat intake was 71%, 12% and 17% of total calories, respectively. Breakfast, lunch, dinner and the between meals provided 20%, 37%, 26% and 18% of total energy intake. Energy and nutrient intake from lunch box was 52-95% of the 1/3 RDAs. Our data suggest that the nutrition education for the meal planners of the subjects is necessary to improve the nutritional status of the subjects. In addition, the school lunch program is recommended.

The purpose of this study was to provide fundamental data for health promotion and improvement of the dietary life in students who receive school lunch support (SLS) by comparative analysis of food service satisfaction, dietary habits, and nutrition intakes according to SLS. The subjects of this study consisted of 258 boys and 233 girls at a middle school in Incheon. The students' average age was 14.9 years, average height was 161.3 cm, and average weight was 52.0 kg. The breakfast eating frequency of the No-SLS (NSLS) group was significantly greater than that of the SLS group (P<0.05). The time spent for eating breakfast in the SLS group was significantly shorter than that of the NSLS group for boys. There was no significant difference in dietary attitudes according to SLS. For satisfaction of the quantity and diversity of the school lunch menu in girls, the SLS group had higher satisfaction than the NSLS group. The daily energy intake of the SLS group was significantly lower than that of the NSLS group in both boys and girls. The majority of daily nutrients intakes in the SLS group were also significantly lower than those in the NSLS group. In summary, the female students in the SLS group were more satisfied with school lunch service than general students. However, SLS students less frequently ate breakfast and showed lower energy and nutrient intakes. Therefore, in order to improve the nutritional status and dietary life of students who receive school lunch support, consistent nutrition management and support in schools are required.

The purpose of this study was to investigate children's nutrient intakes by school lunch. Evaluation of nutrient intakes by school lunch for three days was conducted with 86 children in urban and 64 children in rural of Jeonbuk area. The results of this study were as follows. 1) With respect to amounts of provided nutrients in school lunch, CPF (carbohydrate : protein : fat) energy ratio was 48.6 : 19.7 : 31.6 in urban and was 46.7 : 20.5 : 32.7 in rural. Compared to 1/3 RDA (RDA) of children for 10-12 years, folic acid and zinc were provided below 50 % of RDA. Protein, fat, phosphorus, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C and vitamin E were provided above 125 % of RDA. There were no differences in amounts of provided nutrients-except calcium, vitamin A, vitamin $B_6$, folic acid and zinc-between urban and rural. 2) With respect to amounts of nutrient intakes, CPF energy ratio was 51.1 : 17.4 : 31.5 in urban and 47.5 : 19.7 : 32.7 in rural. Compared to RDA, folic and zinc were below 50 % of RDA. Iron and vitamin $B_6$ were below 75 % of RDA. Protein, fat, phosphorus and vitamin E were above 125 % of RDA. There were significant differences in nutrient intakes between urban and rural. The children in rural showed higher levels of nutrient intakes-energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, vitamins and folic acid-compared to those of children in urban. These results suggest that programs are needed for providing adequate nutrient intakes for children in school lunch and for improving nutrient intakes of children in urban.

The present study was conducted to evaluate nutritional intake by lunch-box of middle school girls who live in Chonbuk area. Anthropometric measurements and food intake from lunch-box over a three day period were investigated in a total of 110 middle school girls from rural (n＝37) and urban (n＝73) areas. The results are summarized as follows : 1. Not all the steamed rice in the lunch-box had enough mixed-cereal. 2. In the survey of food intake by food groups, 70.5% of the food came from the cereal group. 3. The intake of protein, phosphate, Vitamins $B_1 and B_2$, niacine and Vitamin E were adequate, however, the intake of other nutrients was significantly lower than those of one-third of the Korean RDA.4. Protein, lipid, and zinc intakes of the students from the rural area were significantly lower than those of students from the urban area. however, the carbohydrate and dietary fiber intakes of those in the rural area were significantly higher than those of the students in the urban area. 5. The percentage of calories from carbohydrate : protein lipid ratio was 67.6 : 12.2 : 16.9 for students in the rural area and 59.2 : 14.9 : 22.5 respectively for those in the urban area. In Summary, the intake of calcium, iron, Vitamins A, $B_6$, and D, folate and zinc from lunch-box in middle school girls was much lower than that of one-third of the Korean RDA. The intake of carbohydrate and dietary fiber of the students in the rural area was significantly higher, but that of protein, lipids, and zinc was lower than that of the students in the urban area. Therefore, nutritional education programs for both students and their parents should be provided to improve the daily food intake from lunch-box.
