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.

The menu planning is closely tied to the acceptability of the food and the satisfaction of the food service system to its client, therefore national school lunch program(NSLP) menu should consider the food preferences of the students. To provide appropriate information and guidelines about desirable NSLP menu planning, the comparison between the frequency of NSLP menus and food preferences of the students was performed, NSLP menus with cooking method of 776 meals were collected from 10 elementary NSLP schools in Seoul and Kyunggi province, and food preference data was surveyed with 1618 elementary school students from 4 NSLP schools in Korea in 1995. According to the cooking methods, NSLP menus served Kimchi(98.3%), rice(71.4%) and soup(71.1%) frequently. Based on the food groups, NSLP menus served vegetables most frequently(188%), followed by grains(101.4%), milk(100%), meat(57.3%), fruits(50.3%), and so on. By Spearman Rank Correlations analysis, the serving frequencies of vegetable side dishes(r=.33, p=.05) were positively correlated with the students' preference score. According to the cooking method, the serving frequencies of steamed dishes(r=1.0, p=.00), salads(r=1.0, p=.00), Kimchi(r=.85, p=.01) and rice one-dish meal(r=.80, p=.10) were positively correlated with the students' preference score. However, the serving frequencies of the main dishes(r=.13, p=.57) and soup group(r=.15, p=.57) were not significantly correlated with the students' preference score. Even though the serving frequency of fruit were negatively correlated with the students' preference score(r= -.80, p=.10). These results indicated that the NSLP menu planned the vegetable side dishes in accordance with the students' food preferences, but it planned the main dish, soup group, and meat side dish group discordantly. Therefore further efforts are needed to involve the preferred cooking methods for increasing the food acceptability. It could be used for the basic guidelines for menu planning of NSLP, and for the future improvement of NSLP in Korea.

This study was performed to assess the nutrient intakes and diet quality of rural middle school students provided with and without the national school lunch program(NSLP). The data on dietary intakes were obtained by using food record method questionnaires which were collected from 340 rural middle school students provided with(n=177) and without (n=163) NSLP. Diet quality was accessed by NAR(nutrient adequacy ration), MAR(mean adequacy ration), and INQ( index of nutritional quality). Total energy intakes of the boys were 2123 kcal with NSLP and 1857 kcal without NSLP. Total energy intakes of the girls were 1913 kcal with NSLP and 1814 kcal without NSLP. Phosphorus, vitamin A, vitamin E, ascorbic acid, thiamin, riboflavin, and niacin intakes were above the RDA in the NSLP group. For those without NLSP, phosphorus, vitamin E, thiamin intakes were above RDA, however, calcium, iron vitamin A, vitamin $B_6$ were less than the RDA. The mean adequacy ration(MAR), an index of dietary quality was 0.69(with) 0.62(without) for males and 0.62(without) for females The indexes of nutritional quality(INQ) were over 1 for most nutrients except calcium, vitamin A, vitamin B$_2$ and zinc. The study showed that total daily energy and nutrient intakes were significantly higher in students provided with than those without school-lunches. Thus, the school-lunch program is recommenced and necessary to improve the nutritional status of middle school students.

The purpose of this study was no investigate serum lipid levels of primary school children and to estimate their intakes of total fat and fatty acids. Subjects fasting blood samples were obtained and analyzed for serum triglycerides(TG), total cholesterol(Chol) and high density lipoprotein-cholesterol (HDL-Chol). Low density lipoprotein cholesterol (LDL-Chol), LDL-Chol/HDL-Chol ratio(LPH), and atherogenic index(AI) were calculated,. Dietary intake of nutrients was assessed by means of a 24-hour recall method using food models and other measuring tools . The serum levels of TG, Chol and LDL-Chol in girls were higher than those in boys, but the serum HDL-Chol level of girls was lower than that of boys. As the degree of obesity increased, the serum TG level of girls was lower than that of boys. As the degree of oesity increased , the serum TG level of girls increased. The serum LDL-Chol level was higher in obese boys than in normal ones. Percentage s of subjects at risk of cardiovascular disease based on corresponding criteria of TG, Chol,HDL-CHol and LDL-Chol were 25.9%, 7.6%, 20.7% and 10.1%, respectively. The serum TG level of children provided with the national school lunch program(NSLP) was lower than that of children without NLSP. The total fat intake of boys was higher than that of girls, but calorie-adjusted fat intake became similar between the two groups. Intakes of polyunsaturated fatty acids(PUFA), monounsaturated fatty acids(MUFA) and saturated fatty acids(SFA) were 13.3$\pm$9.5g, 16.1$\pm$9.3g and 21.4$\pm$14.2g in boys, respecitively , and 12.6$\pm$11.3g, 15.3$\pm$9.7g and 19.9$\pm$13.1g in girls, respectively . The ratios of polyunsaturated /monoun-saturated /saturated /saturated fatty acids(P/M/S) in boys and girls were 0.7/0.8/1.0 and 0.8/0.8/1.0 respectively. The ratios of $\omega$6/$\omega$3 fatty acids in boys and girls were found to be 12.1 /1.0 and 8.6/1.0 , respectively. These results indicated the urgent need of nutritional education in primary schools to prevent further increase in childhood obesity and hyperlipidemia . Therefore, this study will contribute to the establishment of dietary guidelines and health recommendation for school children.
