This study is to identify the characteristics of the growth and deveolpment, and to assess Obesity Index, BMI and Kaup Index of infants paticipated in a healthy breast-feeding contest. The subjects of this study were 94 breast- feeding infants, ages from 6 to 8 months. Their weight and height were measured and compared with Korean Standards. Their developmental state was tested by DDST(Denver Develop- mental Screening Test) standardized in Korea. The data were analyzed by using the SPSS-WIN 10.0. The result is as follows : 1. The weight of infants was more than Korean Standards, but the height was less. 2. There were statistically significant differences in Obesity Index, BMI and Kaup Index. Obese infants estimated by Obesity Index were about 10％, but by BMI and Kaup Index were 35.1％ and 27.7％. 3. Spearman's rhos of Obesity Index and Kaup Index, Obesity Index and BMI, and Kaup Index and BMI were individually 0.526, 0.528 and 0.753. In conclusion, BMI should be added to the criteria for assessing healthy breast-feeding infants.

Advances in neonatal care system and research have resulted in an increased survival rate among low birth weight infants in the industrialized countries. Recent Korean neonatal mortality and morbidity statistics, and current status of Korean neonatal intensive care facilities were reviewed here for the sake of future improvement and research. Morbidity statistics revealed that perinatal diseases accounted for 80％ of the death of premature infants implying the possibility of its reduction by the vigorous prenatal care service in future.On the basis of extensive studies of nutritional support and growth rate of premature infants, commercial formulas for premature infants have been developed and various aspects of feeding techniques are standardized. However, problem of growth deficit of premature infants remains unsolved as medical problem. NICU specialists are challenged with the tasks of prenatal education or provision of care that minimizes the neurodevelopmental problems seen in preterm infants, various short-term outcome researches have been reported and those are reviewed here to promote research interest in the field of neonatal nursing. Systemic long-term outcome studies are also awaited in Korea for the formulation of welfare policy in future. Nursing science has to embrace all these interdisciplinary studies as their own research field in collaboration with neonatologist, nutritionist, rehabilitation therapist, social workers and teachers.

Purpose: This study was to verify the effects of infant massage on weight recovery from physiologic weight loss, physical development of infants, and identity of their mothers. Method: A study with quasi-experimental design with time delay method was conducted from October 20, 2004 through February 20, 2005 with mothers and infants recruited from postpartum care center. 20 infants in the experimental group (once a day massage group) and 22 control group remained for the final analysis. Data were analyzed using SPSS win 11.0 program by frequency, percentage, mean, standard deviation, t-test and $X^2-test$. Results: There was no significant group difference in weight recovery from physiologic weight loss. However, experiment group showed significant increase in weight and chest circumference in 4 weeks after birth compare to the control group. For changes in behavior, experimental group showed more positive behavioral changes. The mothers who conducted massage for their infants showed higher score of identity as mothers. Conclusion: Since massage applied once a day can be still effective on physical growth of the infants, massage training program for mothers should be developed to apply easily for their infants at home. Further study is suggested to identify influencing factors on performed by mothers and identity as mothers.

One- to three-month-old infants (n=232) were compared their upper arm cumference and skinfold thickness(triceps, subscapular) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). As reported previously, weight, length, head and chest circumferences of these infants were good, and overall growth status was not significantly different by feeding methods, but weight, weight velocity and chest circumference of formula-fed infants were higher than breast-feds at 3month, significantly. Hear, the triceps skinfold thickness of infants at 1, 2, and 3 postpartum months were 7.4, 9.5 and 10.5 mm, respectively. The triceps skinfold thickness of breast-fed infants were higher than formula-feds at 1 and 2 postpartum month, but at 3 month that of formula-fed infants was greater than breast-fed infants, insignificantly. The subscapular skinfold thickness of infants were 6.4, 9.2 and 10.6 mm at 1 to 3 postpartum months, respectively. The upper arm circumference of infants were 11.7, 13.4, 14.3cm, and the arm muscle diameter were 34.5,39.3 and 41.7cm at one to three postpartum months, respectively. The upper arm circumference of male infants was higher than females at 2, 3 postpartum months. Overall, there were no signifiant differences between feeding methods in triceps and subscapular skinfold thickness, upper arm circumference and arm muscle diameter. But 3-month-old formula-fed male infant showed bigger significantly in arm circumference than the breast-feds. From this survey, long-term survey on growth and body composition of large scales might be necessary to determine the effect of feeding methods of infants after 3 months and to set proper body composition standard for infant.

Purpose: Sodium is an essential nutritional electrolyte that affects growth. A low serum sodium concentration in healthy premature infants beyond 2 weeks of life is called late-onset hyponatremia (LOH). Here, we investigated the association between LOH severity and growth outcomes in premature infants. Methods: Medical records of premature infants born at ≤32 weeks of gestation were reviewed. LOH was defined as a serum sodium level <135 mEq/L regardless of sodium replacement after 14 days of life. Cases were divided into two groups, <130 mEq/L (severe) and ≥130 mEq/L (mild). Characteristics and growth parameters were compared between the two groups. Results: A total of 102 premature infants with LOH were included. Gestational age ([GA] 27.7 vs. 29.5 weeks, p<0.001) and birth weight (1.04 vs. 1.34 kg, p<0.001) were significantly lower in the severe group. GA was a risk factor of severe LOH (odds ratio [OR], 1.328, p=0.022), and severe LOH affected the development of bronchopulmonary dysplasia (OR, 2.950, p=0.039) and led to a poor developmental outcome (OR, 9.339, p=0.049). Growth parameters at birth were lower in the severe group, and a lower GA and sepsis negatively affected changes in growth for 3 years after adjustment for time. However, severe LOH was not related to growth changes in premature infants. Conclusion: Severe LOH influenced the development of bronchopulmonary dysplasia and developmental outcomes. However, LOH severity did not affect the growth of premature infants beyond the neonatal period.

This study was carried out to investigate the feeding practices, growth status and correlation with maternal perceptions of breast feeding and lactation with infuts' feeding methods in the Pocheon area. The subjects were 103 infants ranging from 3 to 21 postpartum months and their mothers. The results obtained were as follows : In this survey, 36.9% of the infants were breast-feeding, while 53.4% of them were bottle-feeding, and 9.7% of them were mixed-feeding. The reason for bottle-feeding was due mainly to the lack of breast-milk secretion. Z-scores of weight-f3r-age and height-for-age were similar to Korean standards, but malnutrition and overnutrition were also noticed by kaup index and WLI. The average maternal perceptions of breast-feeding and lactation was 3.7 out of 10 possible points, the breast-feeding group scored 4.7, and formula-feeding and mixed-feeding group scored 3.0. That of BF group was higher than FF+MF groups and was positively correlated with growth status. Therefore to ensure proper growth of infants and to promote breast-feeding, efforts should be given to community nutritional services including nutrition education for the importance of colostrum and breast-milk, practical breast-feeding methods, and nutritional management during pregnancy. Also nutrition education for mothers will be continued to 1-3 postpartum months to promote successful breast-feeding.

This study was carried out to evaluate the calcium and phosphorus intakes and correlation with growth performance of 25male breast and formula-fed infants from 1 to 3 months postpartum. There were four groups breast-fed(BF) and three formula-fed groups(FFM, FFN and FFP). There was no significant difference in the height and weight of infants according to feeding methods and formula brands. Milk intake and the concentration of calcium and phosphorus from human milk and the formulas were measured. The average calcium content of human milk was 26.6$\pm$4.1mg/dl and 13.5$\pm$2.0mg/dl, respectively. The average calcium intakes of the brest-fed and formula-fed infants were 205.5$\pm$29.3mg/day and the 460.5$\pm$70.6mg/day, respectively the average calcium intake of breast-fed infants was significantly lower than that of formula fed infant. The percent of RDA(41%) of breast-fed infants was lower than that(75.4%) of formula fed infant. The average phosphorus intake of the brest-fed and formula-fed infants were 105.1$\pm$20.1mg/day and 288.3$\pm$37.3mg/day, respectively. The precent of RDA(27%) for brest fed was significantly lower than that(75.4%) of formula fed. The Ca/P ratios were 2.1 in brest fed and 1.6 in formula fed infant. The average calcium and phosphorus intakes of the formula fed infants was higher than that of the brest-fed infants. This data suggests the calcium and phosphorus intakes form human milk sufficiently support the growth of infants. Therefore, the level of calcium and phosphorus recommended dietary allowances for infants should be reduced.

This study was carried out to longitudinally investigate the iron and zinc intakes and correlation with growth performance of 25 male breast-and formula-fed infants from 1 to 3 months postpartum, longitudinally. There were four groups breast fed(BF) and three formula fed groups((FFM, FFN and FFP). Milk intakes and the concentration of iron and zinc from human milk and the formulas were measured. The iron content of human milk was $2.07\pm{1.05(0.63~5.65)}\mu{g}$/ml. The zinc content was $2.43\pm{1.14(0.70~5.30)}\mu{/ml.}$ Both were not significantly different among postpartum months. The average iron intake of the breast-fed and formula-fed infants was $1.6\pm{0.7mg/}$day and $8.4\pm{2.3mg}$/day, respectively. The iron intake of breast-fed infants was higher than previous reports. And that of formula-fed infants was higher than the RDA. The average zinc intake of the breast-fed group was $1.9\pm{0.9mg/}$day and formula-fed infants' was $2.7\pm{0.7mg/}$day, which was higher than the RDA. There was no correlation between these mineral intakes and the growth performance during 1 to 3 postpartum months. So, extensive studies of the iron content of human milk and wide cross-sectional studies for establishing iron and zinc recommended dietary allowances for infants are needed.

This study was to investigate the nutrient intake of infants according to the 3 feeding groups which are as follows : breast-feeding(BF), formula-feeding(FF), mixed-feeding(MF) infants. Intake was compared between these 3 groups and present Korean RDA at 2month of age. The energy and the nutrient intake in the FF infants were significantly higher than in the BF infants and MF infants(p<0.05). Unfortunately, the energy and nutrient intake in all groups still do not meet RDA, excluding iron intake in FF infants. It might be suggested that follow-up study is needed to inspect whether the significant lower intakes of energy and nutrients in BF infants than in FF infants can bring about some significant effects on the growth of the infants.

Soy-based formula has been used for centuries in Korea. Soybeans contain phytochemicals with a biochemically active component, isoflavone. Isoflavone is a kind of phytoestrogens, structurally and functionally similar to estrogen. This study was conducted to investigate the effects of soy-based infant formula on growth, development, and isoflavone concentration in the plasma and urine. Thirty-nine healthy infants who were delivered at K university medical center were recruited. Experimental groups were the breast milk group (n = 15, BM) who were fed breast milk, soy-based formula group (n = 10, SBF) who were fed soy-based infant formula, and the casein-based formula group (n = 14, CBF) who were fed casein-based infant formula for 4 months. HPLC analysis was used to measure the concentration of isoflavones. The measurements of infant weight, length, head circumference and chest circumference were all in the normal growth range and were similar among the experimental groups. No significant differences were found in the scores of total mean of infant development test (Development Quotient, DQ) among the experimental groups. The isoflavone content of soy-based formula was significantly higher than. that of breast milk and casein-based formula. Plasma concentration of daidzein and genistein in the infants fed soy-based formula (daidzein : 264.1 ng/ml, genistein : 392.1 ng/ml) was significantly higher (p<.0001) than that in infants fed breast milk (daidzein : 3.4 ng/ml, genistein : 3.8 ng/ml) and casein-based formula (daidzein: 8.1 ng/ml, genistein: 9.3 ng/ml). Also, urinary daidzein and genistein concentrations in infants fed soy-based formula (daidzein: 19.82 $\mu$g/ml, genistein : 17.89 $\mu$g/ml) were significantly higher (p<.001) than those in infants fed breast milk (daidzein: 0.28 $\mu$g/ml, genistein : 0.22 $\mu$g/ml) and casein-based formula (daidzein : 0.45 $\mu$g/ml, genistein : 0.33 $\mu$g/ml).
