Breast Milk Iodine and Iodine Status of Breast-Fed Infants.

Background: Breast milk is the only source of iodine for exclusively breast-fed infants. Iodine status of breast-fed infants depends on iodine in breast milk and also number of feeding in 24 hours. Iodine deficiency and iodine excess both have bad impact on infant’s health. Objective: To measure the iodine in breast milk and to evaluate iodine status of their breast-fed infants. Materials and method: This observational analytical study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka with active cooperation of Kumudini Women’s Medical College Hospital, Mirzapur, Tangail involving fifty lactating mothers and their exclusively breast-fed infants. Early morning urine and breast milk samples were collected in dry and clean plastic container free from any chemical contamination. Urinary iodine was used as indicator for assessing iodine status. All statistical analyses were done by using SPSS (statistical programme for social science) 12 version software package for Windows. Results: The median (range) urinary iodine concentration of lactating mothers and their breast-fed infants were 225.25 μg/L (61.50-530.00) and 225.75 μg/L (100.50-526.00) respectively. The median (range) breast-milk iodine concentration was 157 μg/L (54.50-431.50) which was more than three times of recommended minimum concentration (50 μg/L). Only 2 (4%) lactating mothers had mild biochemical iodine deficiency (UIE, 50-99 μg/L). There was no biochemical iodine deficiency of breast-fed infants. Iodine in breast milk of lactating mothers was positively correlated with their urinary iodine excretion (p<0.01). Infant’s urinary iodine was positively correlated with iodine concentration in breast milk (p<0.01) and with urinary iodine of lactating mothers (p<0.01). Conclusion: Lactating mothers and their breast-fed infants in this study were iodine sufficient. If iodine content of breast-milk is within normal range, 10-12 numbers of feeding in 24 hours for infants is enough to get sufficient iodine from their mother’s milk.

Food and Nutrition Surveillance System/SISVAN: getting to know the feeding habits of infants under 24 months of age / Sistema de Vigilância Alimentar e Nutricional/SISVAN: conhecendo as práticas alimentares de crianças menores de 24 meses

The objective of the Food and Nutrition Surveillance System (SISVAN) is to monitor the food intake of individuals attended by the Brazilian Unified Health System (SUS). The objective of this research was to identify the feeding practices of children under 24 months of age who were attended at Primary Healthcare Units (UBS), using SISVAN, and to assess the relationship with maternal sociodemographic profiles. A cross-sectional study was conducted in order to evaluate 350 children using the Food Consumption Marker Form of SISVAN, and maternal demographic data to identify sociodemographic profiles by exploratory factor analysis. Of the children assessed, 41.1% were under 6 months of age and 98.7% of those between 6 and 23 months had an inadequate intake. Two sociodemographic profiles were found: Profile 1 (mothers with lower income, less education, and recipients of the 'Bolsa Família' conditional family grant program) associated with the consumption of water/tea, cow's milk and salty baby food; and Profile 2 (older mothers with many children and with a larger number of residents in the household) associated with breast milk consumption (p = 0.048). The use of SISVAN made it possible to identify that children had inadequate feeding practices, and Profile 1 appears to be a risk profile for weaning.

O Sistema de Vigilância Alimentar e Nutricional (SISVAN) objetiva monitorar as características do consumo alimentar de indivíduos atendidos pelo Sistema Único de Saúde. O objetivo deste estudo foi identificar as práticas alimentares de crianças menores de 24 meses que frequentam Unidades Básicas de Saúde (UBS), utilizando o SISVAN, e avaliar a relação com perfis sociodemográficos maternos. Estudo transversal que avaliou 350 crianças utilizando-se o Formulário de Marcadores de Consumo Alimentar do SISVAN, e dados sociodemográficos maternos para a identificação dos perfis a partir da análise fatorial exploratória. Das crianças avaliadas, 41,1% das menores de 6 meses e 98,7% daquelas entre 6 e 23 meses apresentaram consumo inadequado. Foram encontrados 2 perfis sociodemográficos: Perfil 1 (mães com menor renda, menor escolaridade e beneficiárias do Programa Bolsa Família) associado com o consumo de água/chá, leite de vaca e papa salgada; e Perfil 2 (mães com mais idade, com maior número de filhos e com maior número de residentes no domicílio) associado com o consumo de leite materno (p= 0,048). A utilização do SISVAN possibilitou identificar que as crianças apresentaram práticas alimentares inadequadas, e o Perfil 1 parece ser um perfil de risco para o desmame.

Comparison of the gut microbiota profile in breast-fed and formula-fed Korean infants using pyrosequencing

BACKGROUND/OBJECTIVES: Feeding in infancy is the most significant determinant of the intestinal microbiota in early life. The aim of this study was to determine the gut microbiota of Korean infants and compare the microbiota obtained between breast-fed and formula-fed Korean infants. SUBJECTS/METHODS: We analyzed the microbial communities in fecal samples collected from twenty 4-week old Korean (ten samples in each breast-fed or formula-fed) infants using pyrosequencing. RESULTS: The fecal microbiota of the 4-week-old Korean infants consisted of the three phyla Actinobacteria, Firmicutes, and Proteobacteria. In addition, five species, including Bifidocbacterium longum, Streptococcus salivarius, Strepotococcus lactarius, Streptococcus pseudopneumoniae, and Lactobacillus gasseri were common commensal intestinal microbiota in all infants. The predominant intestinal microbiota in the breast-fed infants (BFI) included the phylum Actinobacteria (average 70.55%), family Bifidobacteriacea (70.12%), genus Bifidobacterium (70.03%) and species Bifidobacterium longum (69.96%). In the microbiota from the formula-fed infants (FFI), the proportion of the phylum Actinobacteria (40.68%) was less, whereas the proportions of Firmicutes (45.38%) and Proteobacteria (13.85%) as well as the diversity of each taxonomic level were greater, compared to those of the BFI. The probiotic species found in the 4-week-old Korean infants were Bifidobacterium longum, Streptococcus salivarius, and Lactobacillus gasseri. These probiotic species accounted for 93.81% of the microbiota from the BFI, while only 63.80% of the microbiota from the FFI. In particular, B. longum was more abundant in BFI (69.96%) than in FFI (34.17%). CONCLUSIONS: Breast milk supports the growth of B. longum and inhibits others. To the best of our knowledge, this study was the first attempt to analyze the gut microbiota of healthy Korean infants according to the feeding type using pyrosequencing. Our data can be used as a basis for further studies to investigate the development of intestinal microbiota with aging and disease status.

Meningitis por estreptococo ß-hemolítico del grupo B en lactantes / Meningitis in breast-fed infants caused by Group B ß-hemolytic streptococcus

Introducción: el estreptococo ß-hemolítico del grupo B es causa frecuente de sepsis y muerte neonatal. Objetivo: caracterizar el comportamiento de la meningitis por estreptococo ß-hemolítico del grupo B en Cuba. Métodos: se realizó un estudio observacional (descriptivo y analítico) de 57 casos de meningitis por ß-hemolítico del grupo B, con inicio de los síntomas entre el 1ro de enero de 1998 y 31 de diciembre de 2010. Se estimó el riesgo según el año de ocurrencia, la edad, el sexo, la provincia y el municipio, así como la letalidad y la asociación de la demora en la consulta médica y el ingreso hospitalario, con la muerte. Resultados: la incidencia de todo el período fue 0,03/1 000 nacidos vivos y la letalidad alcanzó 31,58 %. La proporción de casos en el sexo masculino (50,9 %) fue muy similar al femenino (49,1 %). Los menores de 2 meses fueron más afectados por la enfermedad (38 casos) y aportaron el 100 % de los fallecidos (18). Las provincias con mayor riesgo fueron Pinar del Río (0,09/1 000 nacidos vivos) y Santiago de Cuba (0,08/1 000 nacidos vivos). El municipio con mayor riesgo fue San Luis, en Santiago de Cuba (0,31/1 000 nacidos vivos). La media de tiempo para la consulta médica fue alrededor de 17 horas, y para el ingreso fue aproximadamente 5 horas. No hubo asociación de la demora para la consulta (RR= 0,66) y el ingreso (RR= 1,22) con la muerte. Conclusiones: la meningitis por estreptococo ß-hemolítico del grupo B constituye una causa importante y prevenible de meningitis y muerte neonatal en Cuba.

Introduction: group B ß-hemolytic streptococcus is a common cause of sepsis and neonatal death, Objective: to characterize the behavior of the Group B ß-hemolytic streptococcus meningitis in Cuba. Methods: an observational, descriptive and analytical study was performed on 57 patients suffering meningitis caused by Group B ß-hemolytic streptococcus, with the onset of symptoms ranging from January 1st 1998 to December 2010. The risk was estimated according to the year of occurrence, the age, the province and the municipality as well as the fatality rate and the association of delay in medical diagnosis and in admission to the hospital and death. Results: the incidence rate of the whole period was 0.03 per 1 000 livebirths and the fatality rate amounted to 31.58 %. The propo9rtion of cases between males and females was very similar (50.9 % and 49.1 % respectively). The infants aged younger than 3 months were more affected by the disease (38 cases) and they accounted for 100 % of those children who died (18 cases). The most risky provinces were Pinar del Rio (9.09 per 1 000 livebirths) and Santiago de Cuba (0.08 per 1 000 livebirths). The municipality with the highest risk index was San Luis in Santiago de Cuba (0.31 per 1 000 livebirhts). The average length of time for medical diagnosis was 17 hours and for admission to the hospital was 5 hours. No association was found between delay in medical diagnosis (RR= 0.66) and in admission to the hospital (RR= 1.22) and death occurrence. Conclusions: Group B ß-hemolytic streptococcus is a significant preventable cause of meningitis and neonatal death.

A Case of Zinc Deficiency Dermatitis in Breast Milk Fed Infant Mimicking Atopic Dermatitis / 소아알레르기및호흡기학회지

Zinc deficiency can result from acrodermatitis enteropathica, an inadequate dietary intake, malabsorption, increased body loss, or intravenous feeding. Unlike acrodermatitis enteropathica, breast feeding-induced acrodermatitis is transient and improves when nursing ends. Breast feeding-induced acrodermatitis is caused by a ZnT-2 transporter dysfunction in the mother's mammary glands. We report a case of a 6-month-old male infant who presented with erythematous patches and plaques involving the perioral, perineal, and acral areas and loose stools since 2 weeks after birth. Atopic dermatitis was considered initially, but the lesions did not respond to topical antibiotics, corticosteroids, or maternal dietary restriction from allergenic food. The patient's serum zinc concentration was low, and the mother's serum and milk had low zinc levels. The differential diagnosis for atopic dermatitis is extensive. Physicians should be alert for the possibility of zinc deficiency dermatitis in breast milk fed infants that mimics atopic dermatitis.

The Characteristics and Diagnostic Methods of Food Protein Induced Proctocolitis / 대한소아소화기영양학회지

Food protein induced proctocolitis (FPIPC) is a non-IgE mediated food allergy. FPIPC occurs exclusively among breast-fed infants within the first months of life. FPIPC is often diagnosed clinically in normal-conditioned infants with rectal bleeding. But FPIPC among infancy with rectal bleeding is less general than conceived. The endoscopic findings reveal an edematous and erythematous mucosa with superficial erosions or ulcerations, bleeding and lymphoid nodular hyperplasia. The prominent eosinophilic infiltrates in the rectosigmoid mucosa are important for the histopathologic diagnosis of FPIPC. However, in explaining eosinophilic infiltration within the lamina propria of the mucosa, it is necessary to differentiate whether it is a part of normal findings or occurs due to inflammatory reactions. Oral food challenge and elimination test is performed to identify the same clinical reaction as the symptom of FPIPC by the administration of a specific type of food to infants. The most common causal food is cow's milk. Thus oral food challenge and elimination test can be the effective way of confirming FPIPC, reducing the possibility of misdiagnosis. The purpose of this report is to identify the characteristics of FPIPC, to introduce its diagnostic methods, and to suggest the future direction of research.

Comportamiento de la bronquiolitis en pacientes ingresados / Behavior of bronchiolitis in admitted patients

INTRODUCCION: la bronquiolitis es una enfermedad aguda respiratoria baja, que ocasiona un alto número de ingresos en lactantes. OBJETIVO: identificar el comportamiento de la bronquiolitis para poder tomar decisiones y trazar estrategias sanitarias y administrativas, así como pautas institucionales para el Servicio de Urgencias, en relación con los criterios de ingreso y la prevención de los factores de riesgo modificables más frecuentes que presentan estos pacientes. MÉTODOS: estudio descriptivo, retrospectivo y transversal de 67 lactantes egresados con el diagnóstico de bronquiolitis durante los meses de septiembre 2005, febrero 2006, septiembre 2006 y febrero 2007. Se revisaron las historias clínicas de 70 lactantes, y se excluyeron 3 por no tener los elementos al examen físico para clasificar la severidad de la enfermedad. RESULTADOS: 57 pacientes fueron menores de 6 meses (85 por ciento), 43 del sexo masculino (64 por ciento), 54 de nuestros casos (80 por ciento) tuvieron una lactancia materna inadecuada, en 44 niños (66 por ciento ) existían fumadores en la vivienda, 49 de los pacientes (73 por ciento) fueron clasificados según la severidad de la enfermedad en moderados y graves. CONCLUSIONES: el 100 por ciento de nuestros pacientes presentaron algún factor de riesgo de la enfermedad, con predominio de la edad menor de 6 meses, sexo masculino, lactancia materna inadecuada o ausente, y fumadores en la vivienda. En cuanto a la severidad de la enfermedad predominaron los pacientes evaluados como moderados

INTRODUCTION: bronchiolitis is a low respiratory acute disease provoking a high number of admissions in breast-fed babies. OBJECTIVE: to identify the behavior of the bronchiolitis to take decisions and to design administrative and health strategies, as well as institutional guidelines for the Emergence Service, related to the admission criteria and prevention of the more frequent modifiable risk factors present in these patients. METHODS: a cross-sectional, retrospective and descriptive study was conducted in 67 breast-fed children discharged and diagnosed with bronchiolitis during September, 2005, February, 2006 and February, 2007. The medical records from 70 breast-fed children were reviewed excluding three of them due to a lack of elements in the physical examination to classify the severity of the entity. RESULTS: fifty five patients were aged under 6 months (85 percent), 43 of male sex (64 percent), and 54 of our cases (80 percent) had a inappropriate breastfeeding, 44 children(66 percent) had a history of family smokers, 49 of patients (73 percent) were classified as moderate and severe according the severity of the entity. CONCLUSIONS: the 100 percent of our patients had some risk factor of the disease, with predominance of an age under 6 months, male sex, inappropriate or lacking breastfeeding and a history of family smokers. As regards the severity of disease there was predominance of patients assessed as moderate

Síndrome de kawasaki: presentación de un caso poco común / Kawasaki syndrome: presentation of an uncommon case

La enfermedad de Kawasaki es un proceso vasculítico multisistémico cuya etiología es poco conocida. La presentación clínica es florida y su evolución está condicionada al inicio temprano de la terapia específica con gammaglobulinas, de allí la importancia de un diagnóstico precoz. Habitualmente estos casos cursan con dilatación del lecho arterial coronario siendo excepcional la aparición de alteraciones a nivel de arterias de mayor calibre, menos común aneurismas a nivel cerebral, que confiere un peor pronóstico para estos pacientes. Presentamos el caso de lactante de 3 meses de edad con aneurisma de ambas arterias coronarias, arteria subclavia izquierda, cerebral media derecha y ambas Iliacas, y obstrucción de las mismas.

Kawasaki disease, a multisystem vasculitis of unknown etiology can present in various ways. It is crucial to make an early diagnosis, and consequently give gamma globulin in order to abort its insidious evolution and not infrequently fatal outcome. Aneurysms and obstruction of the coronary arteries are the most characteristic presentations. Other large vessels may be involved, with the cerebral circulation being affected least often but having the worst prognosis. We present a clinical case of a 3 month old breast fed infant with aneurysms and obstructions in both coronary arteries, the left subclavian, right middle cerebral, and both iliac arteries.

A Case of Transient Acrodermatitis Enteropathica in A Breast-fed Full-term Infant / 대한피부과학회지

A 5 month-old, breast-fed, full-term female infant presented with an acral and periorificial dermatitis. Her serum zinc level was low. Her mother's serum zinc level was normal and breast milk zinc was slightly reduced. The infant responded rapidly to zinc therapy. After interruption of zinc therapy, she showed slightly reduced zinc levels, but no relapse, while receiving powdered milk and other baby foods. To maintain zinc serum level, zinc was readministered for 4 weeks. Follow-up zinc levels were normal after discontinuation of the zinc readministration. A diagnosis of transient acrodermatitis enteropathica was made based on the above findings.

A Case of Hypocalcemia due to Vitamin D Deficiency in Exclusively Breast-fed Infant / 대한소아내분비학회지

Hypocalcemia is due to Hypoparathyroidism, Vitamin D deficiency, Hypomagnesemia, Inadequate calcium intake. The benefits of breast-feeding are well established. There are no need to supply calcium or Vitamin D in breast-fed infant. We report a case of infantile hypocalcemia caused by Vitamin D deficiency in exclusively breast-fed infant. He had no hypocalcemic symptom and hypocalcemia was found incidentally by routine laboratory tests during pneumonia treatment. He was presented with a low serum calcium level and 1,25(OH)2 Vit D3 level and high PTH. He was improved by Calcium and Vitamin D supplement. After then his mother continued breast feeding exclusively and resisted to feed her baby weaning food. During follow up period, hypocalcemia was recheked after discontinuation of vitamin D supplement. At 11 months of age, the calcium level was normal without vitamin D supplement after he had eaten weaning food. This report describes a case of hypocalcemia induced by vitamin D deficiency in exclusively breast-fed infant, with review of the literature.

Clinical Features and the Natural History of Dietary Protein Induced Proctocolitis: a Study on the Elimination of Offending Foods from the Maternal Diet / 대한소아소화기영양학회지

PURPOSE: The aim of this study was to identify the clinical features and natural history of dietary protein induced proctocolitis (DPIPC) and to detect the causative foods of DPIPC, and to evaluate the effect of elimination of the foods on the course of the disease. METHODS: Between March 2003 and July 2004, data from 30 consecutive patients with DPIPC who were followed for over 6 months, was reviewed. The diagnostic criterion used for DPIPC was an increase in the number of eosinophils in the lamina propria (> or =60 per 10 high-power fields). In breast feeding mothers, 5 highly allergenic foods were eliminated from the maternal diet for 7 days, namely, allergenic food groups such as dairy products, eggs, nuts and soybean, fish and shellfish, and wheat and buckwheat. We observed the disappearance or appearance of hematochezia after elimination or challenge with the offending foods. RESULTS: Before diagnosis infants were breast-fed (93.3%) or formula-fed (6.7%). Mean age at symptom onset was 11.5+/-5.1 (5~24) weeks, and mean age at diagnosis was 17.8+/-9.5 (8~56) weeks. Duration from symptom onset to diagnosis was 6.3+/-6.7 (0~36) weeks. Mean peripheral blood eosinophil count was 478+/-320 (40~1,790)/mm3 and eosinophilia (>250/mm3) was observedin 90.0% of patients. None of patients were found to have an increased serum IgE level. Of 15 patients that received sigmoidoscopy, nodular hyperplasia with erosion was observed in 93.3%. Of 27 patients whose mother ate the diet eliminated the 5 food groups, hematochezia diappeared in 74.1% of patients. Offending foods were identified as dairy products (37.5%), wheat and buckwheat (27.5%), fish and shellfish (20.0%), nuts and soybean (7.5%) and eggs (7.5%). A free maternal diet without patient's clinical symptoms was achieved at 29.4+/-8.7 (9~44) weeks of patient's age, and a free baby diet without blood in stools was achieved at 37.5+/-9.7 (12~56) weeks of age. CONCLUSION: DPIPC commonly occurs in exclusively breast-fed babies. Elimination of the above-mentioned 5 hyper-allergenic food groups from the maternal diet for 7days enables the detection of the offending foods. DPIPC is a transient disorder and 96.0% of patients can tolerate the offending foods at 12 months of age.

Vitamin A Intake of Exclusively Breast-Fed Infants in Cheongju and Anseong areas

This study was longitudinally conducted to evaluate vitamin A intake of exclusively breast-fed infants compared with the Recommended Dietary Allowances (RDA) for Korean infants. Twenty-seven Korean lactating women and their infants during the first 6 months of lactation in Cheongju and Anseong areas were participated. Retinol and beta-carotene contents in the milk were determined using HPLC and also the milk consumption of the infants was measured by the test-weighing methods. Vitamin A (retinol and beta-carotene) contents of the milk were 65.7, 57.2, 48.1, 43.9, 38.2, 38.7 and 44.0 R.E./100 ml, and vitamin A intakes of the breast-fed infants were 361, 402, 348, 331, 304, 305 and 322 R.E./day at 0.5, 1, 2, 3, 4, 5 and 6 month of lactation, respectively. The average intake of vitamin A was 339.1 R.E./day and the percentage to RDA was 96.9% during 6 months. Vitamin A intakes per body weight of the breast-fed infants were 96.7, 88.3, 62.1, 50.0, 41.8, 39.3 and 39.6 R.E./kg/day at 0.5, 1, 2, 3, 4, 5 and 6 month. The body weight increased normally from 3.4 +/- 0.5 kg at birth during lactation. It is suggested that the breast-fed infants in Cheongju and Anseong areas consumed adequately vitamin A from the milk compared with RDA for Korean infants.

A Case of Transient Acrodermatitis Enteropathica / 대한피부과학회지

Acrodermatitis enteropathica is a rare autosomal recessive disorder affecting early infancy. This syndrome is characterized by acral and periorificial dermatitis, alopecia and intractable diarrhea. Whereas hereditary acrodermatitis enteropathica is caused by mutation affecting intestinal zinc absorption, transient acrodermatitis enteropathica is caused by inadequate supply or malabsorption of zinc in the premature infant. We report a case of transient acrodermatitis enteropathica in a 5-month-old, breast-fed premature infant.

Protein, Ca, Mg and P Intakes of Breast-fed Infants during Lactation

This study was longitudinally conducted to evaluate the intakes of protein, Ca, Mg and P of exclusively breast-fed infants compared with the Recommended Dietary Allowances (RDA) for Korean infants. Twenty Korean lactating women and their infants during the first 3 months of lactation in Incheon area were participated. Protein, Ca and Mg, and P contents in the milk were determined using semimicro Kjeldahl (N X 6.38) , atomic absorption spectrophotometer and colorimeter, respectively, and also the milk consumption of the infants was measured by the test-weighing method. Protein contents of the milk were 1.96, 1.63, 1.51, 1.25 and 1.16 g/100 ml, and protein intakes of the breast-fed infants were 9.00, 9.85, 9.17, 8.97 and 7.76 g/day at 7, 15, 30, 60 and 90 days postpartum. The average protein intake per body weight of the breast-fed infants was 1.84 g/kg/day. The average intakes of Ca, Mg, P were 172.1 mg/day, 15.2 mg/day and 91.4 mg/day, respectively, and the average Ca/P ratio was 1.91. There was positive correlation between protein and Ca, protein and p, and Ca and P contents while negative correlation between Mg and P, The body weight of breast-fed infants increased normally from 3.6+/-0.41 g at birth to three month during lactation. It is suggested that the breast-fed infants in Incheon area consume almost adequately protein, Ca and P from the milk compared with RDA for Korean infants.

Comparison of Hematologic and Serum Biochemistric Values at 1 Month of Age between Breast-fed and Formula-fed Infants

PURPOSE: We compared the hematologic data, serum biochemical and immunoglobulin values at 1 month of age and anthropometric variables at 1, 4, and 6 months of age between breast-fed and formula-fed infants. METHODS: Healthy full-term infants whose parents agreed with our study were enrolled. The hematologic and serum biochemical and immunoglobulin values were measured at birth and at 1 month of age. Anthropometric variables were measured at birth and 1, 4, and 6 months of age. RESULTS: In general, the hematologic and serum biochemical and immunoglobulin values were not different at 1 month of age between breast-fed and formula-fed infants. And there were no differences in growth between breast-fed and formula-fed infants from 0 to 6 months. CONCLUSION: There were no differences in growth and almost same values of hematology, serum biochemistry, immunoglobulin between breast-fed and formula-fed infants.

A Longitudinal Study of Calcium and Phosphorus Intakes of Korean Infants from 1 to 3 Months in Breast-Fed vs Formula-Fed Infants / 대한지역사회영양학회지

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+/-4.1mg/dl and 13.5+/-2.0mg/dl, respectively. The average calcium intakes of the brest-fed and formula-fed infants were 205.5+/-29.3mg/day and the 460.5+/-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+/-20.1mg/day and 288.3+/-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.

Comparison of Immunoglobulin Levels in Serum between Breast- and Formula-fed Newborns / 대한임상병리학회지

BACKGROUND: It had been well known that breast feeding to infants has many advantages and benefits comparing to formula feeding. So, We performed this study to clarify the relationship between immunoglobulin (Ig) levels and diet during newborn period. METHODS: We measured the levels of IgG, IgA and IgM by Array 360 System (Beckman Instruments, CA, U.S.A). Subjects were 29 breast-fed and 13 formula-fed newborns. We evaluated the results and analyzed the change of concentrations of IgG, IgA and IgM according to diet, sex and postnatal period. RESULTS: The levels of IgG, IgA and IgM in breast-fed newborns at postnatal 1-day were higher than formula-fed newborns, but the levels of Ig G and Ig A in formula-fed newborns at postnatal 30-day were higher than breast-fed newborns. CONCLUSIONS: There was no clinical signficance in the difference of IgG, IgA and IgM levels according to diet, sex and postnatal period, respectively.

Concentrations of Major Minerals and Trace Elements in Sera of The Breast-fed and Formula-fed Infants / 대한지역사회영양학회지

The serum concentrations of the major minerals(calcium, phosphorus, magnesium, sodium, potassium) and trace elements(iron, Zinc, copper manganese)were datermined in 23 breast fed infants living in Eumsung, Choong-buk region. The results obtained are summarized as follows: 1)The mean levels of calcium, phosphorus, magnesium, sodium and potassium of the serum of total subjects were 8.15+/-0.33mg/dI, 11.06+/-0.16mg/dI, 2.00+/-0.14mg/dI, 3.4476+/-17.99mg/dI and 9.06+/-2.04mg/dI respectively. 2)The serum concentrations of iron, zinc, copper and manganese in total subjects averaged 95.83+/-0.33mg/dI, 93.79+/-7.06 microgram/dI and 98.57+/-7.06 microgram/dI and 4.93+/-0.62 microgram/dI respecitively. 3)Breast fed infants had significantly higher serum calcim, magnesium, sodium and iron concentrations than the formula fed groups. Otherwise, serum potassium, copper and manganese levels in breast milk fed infants were significantly lower than those in formula fed infants. 4) In formula fed infants, serum potassium and copper levels increased increased significantly with months after birth.

A Study on Nutritional Status of Iron and Lipids in Infants

PURPOSE: This study was conducted to get baseline data to establish a guideline for the infant nutrition by observing the feeding practice and nutritional intake during infancy and evaluationg the nutritional status of iron and lipids at 12-month-old infants. METHODS: This survery was cnducted from July to November, 1992. Subjects were healthy infants who were brought to Yeungnam University Hospital for vaccination. We followed up feeding methods for 6 months in 120 infants, and laboratory tests which include hemoglobin, fematocrit, MCHC, ferritin, total cholesterol, HDL-cholesterol, triglyceride and urea nitrogen/creatinine ratio were done in 36 infants at 12 months of age. RESULTS: Male to female sex ratio was 1.6:1 in total 120 study infants. Among 36 infants who took laboratory tests, five infants were breast-fed, 25 were formula-fed, and 6 were mexed-fed. Percentage of the formula-fed infants increased as their monthly age increases. Although 54.2% of the studied infants were started weaning diet at four months of age, 10.8% of infants were not given any weaning diet until 6 month of age. Breastfed infnats had lower hemoglobin(10.6+/-1.8g/dl), hematocrit(32.6+/-3.6%), serum ferritin(13.6+/-13.1ng/ml)(p<0.05), and 15.6% of them had anemia and 16.7% of them had iron deficiency. Serum lipids levels except total cholesterol in breaset-fed female infants were comparable between groups. CONCLUSIONS: We confirm that the incidence of iron deficiency anemia was increased in breast fed infants and there was no difference in lipids levels according to different feeding methods. Adequate iron supplementation through weaning diets is one of the most important problems in breast milk feeding
