This study was carried out to investigate the experiences of breast milk feeding information and education, breast milk feeding knowledge and attitude and needs for breast milk feeding nutrition education of high school students to encourage breast milk feeding. The subjects were 565 (male: 250, female: 315) high school students from first to third grade. The results obtained were as follows: In this survey, only 30.0% of subjects experienced breast milk feeding information and only 6.1% of subjects had breast milk feeding education. And the subjects showed the average scores of knowledge of breast milk feeding were 0.29 points of 1 point. Subjects knew well about ingredients of breast milk but they didn't know well about the physiology and method of breast milk feeding and benefits of breast milk feeding for mothers. The average scores of attitude of breast milk feeding were 3.03 points of 4 points, showed slight positive attitudes of breast milk feeding, but they had negative attitudes of emotional and practical aspects. The future plan of feeding practices was breast milk feeding 35.9% and 60.0% of formula milk feeding. A concern was that the students showed high ratio of formula milk feeding plan and they decided by incorrect knowledge of breast milk feeding. The 33.5% of students answered high school students will need breast milk feeding nutrition education, and they thought hospital faculties were the proper educators of breast milk feeding education, but dietitians were recomended as educators because of easy access at school and good knowledge of life-cycle nutrition. Therefore, to encourage breast milk feeding by mothers and supporters of breast milk feeding, breast milk feeding nutrition education is needed urgently among high school male and female students. And nutrition education programs will have to contain benefits of breast milk for babies and mothers and physiology and practical methods of breast milk feeding to improve emotional and practical attitudes for breast milk feeding. Nationwide campaign to promote breast milk feeding at public areas will be needed.

This study was carried out using a questionnaire in order to investigate factors affecting the status and the method of infant feeding in Incheon area. The subjects were 126 monthers of infants ranging from 3 months to 18 months. The results are : the percentages of those feeding colostrum and breast milk has decreased in comparison with the previous results. But the percentage of breast-feeding gets higher in a case where colostrum or breast milk is first fed after delivery. Also frequency and birth order of child plays a part : the more frequently monthers try to feed breast milk in the earliest period of feeding, the more they keep breast-feeding, and the latter-born(the second-born or the third born) children get more chances to be breast-fed than the first-born. Another noticeable factor is what babies feed on during hospitalization. if they get fed more breast milk than infant formula while they are in hospital, they tend to keep feeding on breast milk after they come back home. Breast-feeding group have good knowledge and information abut the importance of breast-feeding. The data shows that they believe the superiority of breast milk.

This study was performed to investigate the vitamin A intake of exclusively breast-fed infants and to compare the value with the Recommended Dietary Allollwances(BDA) for Korean infants. We examined retinol and ${\beta}$-carotene contents of breast milk in 32 lactating women by HPLC analysis and also the consumed volume of the milk of their infants by the test-weighing method during the first 5 months of lactation. Total vitamin A contents of the milk shelved 67.3, 56.5, 51.2, 45.2, 39.0 and 34.lR.E./100m1 at 0.5, 1, 2, 3, 4 and 5 months of lactation respectively. Vitamin A intake of breast-fed infants were 320, 371, 368, 325, 292 and 251R.E/day during the five-month nursing period. Vitamin A intake per body weight of breast-fed infants was measured at 86.4, 79.8, 63.6, 49.1, 40.0 and 31.9R.E/kg/day. Body weight gain of infants was not affected by the vitamin A intake from the milk during the lactation. We conclude that breast-fed infants most likely receives vitamin A from the milk adequately compared with the RDA for Korean infants. (Korean J Nutrition 31(9) : 1433-1439, 1998)

Purpose: In this study the effects of breast massage on breast pain, breast-milk sodium, and newborn suckling in early postpartum mothers were investigated. Methods: The design was a non-synchronized nonequivalent control group pretest-post-test design. Sixty postpartum mothers who were admitted to a postpartum care center and had problems with breastfeeding were recruited. Of these mothers, 44 were assigned to the intervention group and received two 30-minute breast massages within 10 days of postpartum period. The others were assigned control group and received only routine care. Breast pain was measured using a numeric pain scale and number of times newborns suckled was observed throughout breastfeeding. Breast milk was self-collected to evaluate breast-milk sodium. Results: Mean age of postpartum mothers was 30 years old. Compared to the control group, women in the intervention group reported significant decreases in breast pain (p<.001), increases in number of times newborns suckled after the first and second massage (p<.001), and a decrease in breast-milk sodium after the first massage (p=.034). Conclusion: Breast massage may have effects on relieving breast pain, decreasing breast-milk sodium, and improving newborn suckling. Breast massage can be used to solve breast problems. Further research is needed to validate our findings.

In order to investigate the longitudinal changes on zinc secretion of lactating women and zinc intake of breast-fed infants, we examined 20 lactating women(10 primipare and 10 multipare) and their infants during the first 90 days postpartum. We measured the consumed volume of human milk by test-weighing method and zinc concentration by atomic absorption spectophotometry after wet digestion. Weight gain of infants was -5.7, 54.1, 46.3, 42.0 and 32.3g/day at 7, 15, 30, 60 and 90 days postpartum, respectively. The secretion volume of human milk was 527, 608, 724, 841 and 798g/day respectively. The consumed volume of human milk of breast-fed infants was 432, 503, 603, 715 and 715g/day. The intake level of breast milk to secretion volume reached 85.0% in average. The zinc concentration of the milk was 4.29, 3.32, 2.52, 1.62 and 1.18mg/l, and the zinc intake of breast-fed infants was 1.80, 1.69, 1.45, 1.15 and 0.70mg/day. Zine intake per body weight of infants averaged 0.32mg/kg/day during the first 90 days postpartum. The average zinc intake of breast-fed infants was 1.36mg/day, which is 27.2% of the recommended daily allowance for 0-4-month-old infants.

In order to investigate the body weight change and human milk intake of breast-fed infants, we examined thirty-three infants with test-weing method in Sokcho area during the first 5 months of lactation. The average birth weight of infants was 3300g. They grew 3300, 3805, 4676, 5878, 6786, 7403, and 8111g when they became 0.5, 1, 2, 3, 4, and 5 months old. The is human milk intake was 515, 650, 718, 731, 746 and 796g/day during the lactatin. Human milk intake of boys was significantly higher than that of girls at 1(p<0.05), 2(p<0.01), and 3(p<0.01) months of lactation. During lactatin, the number of feedings per day decrerased. The human milk intakes per feeding had increased from 54.4g at 0.5 months to 98.9g at 5 months of lactation The human milk intake on infants was not affected by gestational period and birth weight. From this survey, we found a difference between boys and girls in human milk intake.

In order to investigate the vitamin I intake of exclusively breast-fed infants, we examined 33 lactating women and their infants at 0.5, 1, 2, 3, 4 and 5 months of lactation. Vitamin E contents of human milk were determined by HPLC analysis. Vitamin E contents of the milk showed 539, 520, 464, 422, 409 and 351$\mu\textrm{g}$/100m1 during the lactation respectively. Vitamin E contents of the human milk were not affected by energy, lipid and protein consumption of lactating women. Vitamin E intake of breast-fed infants averaged 3375 and 269$\mu\textrm{g}$/day in boys and girls during the first 5 months of lactation. Vitamin E intake per body weight of breast-fed infants appeared 725, 752, 600, 461, 420 and 334$\mu\textrm{g}$/kg/day respectively. We conclude that breast-fed infants most likely receives adequate vitamin E from the human milk compared with recommended dietary allowances for Korean infants.

This study was carried out to investigate the lactation and weaning practice of infants and their mothers' attitude on infant nutrition. We interviewed 152 mothers in three pediatric clinics located in Sokcho city. From this survey, $76.3\%$ of infants was fed colostrum milk during first one week of life. During the first 4 months, $31.6\%$ of infants was fed breast-milk, while $42.8\%$ of them was fed bottled-milk. More housewives fed their babies with breast milk than the working mothers. Infants ate first weaning food at 5.73$\pm$1.86 months of life. Highly educated mothers showed positive response to the questionnaire : Breast-feeding is good for baby but it requires mother's sacrifice, and Breast-feeding may ruin the good shape of mothers. Highly income mothers responded negatively to the statement : Breast-feeding is not a must for infants since bottled-milk is a good substitution for breast-milk. Comparing with the mothers whose income was about 1 -2 million won per month, with ones who got paid less than 1 million won per month the former responded positively to : Breast-feeding is good for baby but it requires mother's sacrifice. Mothers recognized the importance of weaning in the following order : Supply of nutrition, Enforcement of digestion and absorption capability, Variety of taste, Disease prevention, Development of self-reliance, and Development of baby tooth. To improve the infants' nutritional status, education program on infant nutrition should be organized and run for the pregnant and lactating women in obstetrician and pediatric clinics and through the mass media as well.

This study was done to determine the trans fatty acid (tFA) composition of human milk from postpartum to sixth months after delivery, to investigate the tFA intake of lactating women, and to estimate the intakes of tFA by infants exclusively fed breast milk. A total of 27 lactating Korean women participated to this study voluntarily, gave their breast milk, and responded to an investigation of their diets. The lactating women consumed 2.3-2.8 g/d of tFAs over the period of the first, second, third, and sixth months postpartum, which was 3.4-4.9% of the total fat intake and 0.8%-1.2% of the total energy intake. The proportions of tFAs in the breast milk were 1.89% in colostrum, 1.78% in transitional milk, and 1.78-2.25 in mature milk of the first, second, third, and sixth months postpartum. The tFAs of the breast milk identified in this study were C16:1n9t, C18:1n9t, C18:2n6t12t, C18:2n6t12c, C18:2n6t12t and C18:2n6t11t. Among them, C18:1n9t was predominant, which made up 59.26% of all tFAs in cob strum, 62.36% in transitional milk, and 64.42% in mature milk. The proportion of total tFA was unchanged with time, although some significant differences were noted for individual tFAs. The percentages of C18:2n6t12c and C18:2n6c12t decreased over the study period. Estimated tFA intake of the exclusively breast-fed infants was 0.18 g/d when fed colostrum, 0.29 g/d when fed transitional milk, and 0.53 g/d when fed mature milk until the sixth month of postpartum. Those were 0.5%, 0.8%, and 1.1% of the total energy intake. The results in this study indicate that lactating Korean women consume not a large quantity of tFAs, secrete breast milk not containing much tFA, and the estimated intake of tFAs by infants fed exclusively breast milk is not great.

Purpose: The purpose of this research is to provide basic informations for the encouragements of premature infants' breast feeding. Method: From August 10 to October 9, 2002, we have carried out a statical research which surveyed 148 mothers of premature infants registered in NICU. The sample had generated cluster-randomly from 25 General Hospitals, all over the Korea peninsula and being surveyed with 74 questionnaires. Result: Mean hospitalized day of premature infants was 27.9 days. The mean total feeding period was 19.1 days and continuous breast feeding period 12.4days. They were interested in breast feeding education-they answered that they would join the breast feeding education if they were given the chance 87.8％. There was significant relation between babies fed only breast milk and the body weight of birth(p<.05). The reasons why mother gave the baby her breast milk include 'for her baby's health' and 'people said breast milk is good for babies' with a portion of 99％. The main reason why mothers could not execute breast feeding was 'the deficit of breast milk volume' 50.0％ and other reason were 'because of start to support more nutritions '18.2％, 'difficulty to carry out the breast milk to hospital'13.6％. The reasen why mothers could not try breast feeding at first were 'deficit of breast milk volume'37.0％, 'not to be prepared for breast feeding because of unexpected delivery'32.6％. Conclusion: We need a program to inform importance and excellent of the breast feeding and a plan to increase the premature infants' breast feeding through the importation of fortifier.
