The objectives of this study were to examine the growth pattern of infants by anthropometric measurement according to the 5 feeding practices of infants with the subject of two hundred healthy newborn babies from their birth till sixty month of age at intervals of two months. Breast group(BF, n=38), formula group(FF, n=102) and mixed group(ME, n=14) were fed breast milk, formula milk, breast and formula milk, from birth till 6 mo. of age, respectively. Convert 1 group (C1F, n=14) and covert 2 group(CF, n=32) were fed breast milk and mixed milk at 2 mo. of age afterthat switched to formula milk, respectively. From these, the following results were made. All the infants of this study showed superiority to Korean standard growth rate in regards to each growth item for each month age. In the case of males, at their birth, the subscapular skinfold thickness and the total skin fold thickness in the BF group was significantly larger than in MF group and FF group(p<0.05). At 6th month age, the chese circumference of MF group was 45.9cm, and significantly larger than those of BF, FF and C2F groups(p<0.05). In the case of females, at theri birth and 2nd month age, there was no difference among all the feeding groups in regards to each growth rate. At 4th month age, the Kauf index of C1F group was 16.21 and significantly lower than those of four groups(p<0.05). And total skinfold thickness in BF group was larger than in C1F group. The increase rate per month age of all growth items were larger at 2nd month age than at the later months both in males and in females. And until 2nd month age males showed more increase than females in regards to each growth item but after 2nd month age, this sapect did not show up. Multiple linear regression was used to determine predictive factors for infant growth. It was expected that at 6th month age, in the measurement of head circumference and chest circumference and cross-sectional fat area, BF-males were bigger by 22-39% of the explanation index than the infants of other groups. As a result, in spite of the significant lower intakes of energy and nutrients in breast-fed infants than in formula-fed infants, breast-fed infants showed more growth than the average of Korean infant standard growth rate at every month age, and showed no significant growth difference among feeding groups.
For the purpose of investigating the weaning practice for infants, this study of 251 infants aged from 3 months to 2 years old was conducted in Daejeon City during the the period of August 9 through 23, 1978. The results obtained were as follows: About 60% of the infants were breast-fed, 27.6%, mixed-fed, and 12.0%, bottled-fed. The reason for bottle-feeding was either the lack of breast-milk secretion or ill-health of mothers. There was no significant difference in the feeding methods according to a level of mother's education. Sixty precent of the infants began to be weaned 6. months. The most of the infants were completely weaned within 18 months. The knowledge on weaning was mainly obtained from the publications, such as newspapers, journals for women, child care booklets, etc. The difficulties in the weaning practice were the shortage of knowledge on weaning and the unacceptability by the infants. Liquid or semi-liquid foods were firstly given to the more than 60% of the infants as introducing weaning foods, while 23.3% of the babies were given solid foods. Interestingly, the earlier the birth order was, the more babies were given liquid or semi-liquid foods, The motives for weaning was either the boby's demand for other foods than milk(41.3%) or the lack of breast-milk secretion (31.3%). In the selection of supplementary foods, the nutritional value was given the highest consideration) (54.9%). many mothers (64.2%) prepared supplementary foods for infants at home, while 23.1% used commercial body foods and 12.7% gave infants adult's meals as supplementary foods. The major materials for home-made supplementary foods were fruits and vegetables (41.5%) and cereals (37.5%). The commercial supplementary foods (mainly powdered from) were not used much (never used; 53.6%) and even in the babies, who had consumed them once, nearly half of the babies (42.9) did not eat well. Accordingly, the many mothers (68.8%) welcomed the development of the domestic supplementary foods in good quality and one-third (31.2%) responded that they would consume them regardless of the price.
This study was undertaken to determine talc fatty acid intakes of lactating women and breast fed infants. Food consumptions of lactating women were measured at 3 4nd 9 days find 4, 8 and 12 weeks postpartum, respectively and diet samples were collected at the same time. Breast milk and blood samples were collected at 12 weeks postpartum. Fatty acid profiles of diet and breast milk were analyzed with GC. Total fatty acid intakes, fat percentage of energy, P/M/S and n-6/n-3 ratios of lactating women were 50.7 g/d, 20.9$\%$, 0.6/0.9/1 and 4.0/l, respect timely, over the first 12 weeks of postpartum and were not significantly different according to the lactating stages. Total fatty acid intakes and fat percentage of energy of the infects aged 12 weeks through the breast milk alone were 18.9 g/d and 44.8. This study shows that the linoleic acid percentage of energy intake in infants was 6.7$\%$, which was in optimum and/or high level to generally recommended guideline. DHA intakes of lactating women were positively correlated with those of infants from breast mil.
The development of the gut is controlled and modulated by different interacting mechanisms, such as genetic endowment, intrinsic biological regulatory functions, environment influences and last but no least, the diet influence. In this work, we compared the fecal microbiota of breast-fed (BF), formula-fed (FF), and mixed-fed (MF) infants from Hebei Province, China. By using high-throughput 16S rDNA sequencing analyses, we found some differences in gut microbiota in the three groups. Firmicutes and Proteobacteria were the dominant bacteria at the phylum level in the three groups, where FF infants showed a significant depletion in Bacteroidetes (p < 0.001) and Actinobacteria (p < 0.05). Enterobacteriaceae was the dominant bacteria at the family level in the three groups, but FF infants showed higher Enterobacteriaceae enrichment than BF and MF infants (p < 0.05); the abundance of the Bifidobacteriaceae was only 8.16% in the feces of BF infants, but higher than in MF and FF infants (p < 0.05). The number of genera detected (abundance >0.01%) in BF, MF, and FF infants was only 15, 16, and 13, respectively. This study could provide more accurate and scientific data for the future study of infant intestinal flora.

Purpose : Iron-deficiency anemia remains the most common nutritional deficiency in young infants. This study aimed to survey the actual condition of feeding patterns and weaning diet and to study the association between these factors and the prevalence of anemia in infants aged over 9 months. Methods : We studied 171 infants aged 9-24 months who were hospitalized in the general ward with mild to moderate acute illnesses. The mothers answered a questionnaire about the feeding patterns and the status of the weaning diet of their infants. The infants were divided into three groups: infants who were exclusively breast-fed, those who had been given mixed feeding, and artificial milk feeders. Results : The incidence of anemia was significantly higher in exclusively breast-fed infants (23/68, 33.8%) than in the infants with mixed feeding (11/62, 17.7%) and artificial milk feeders (5/41, 12.1%). The mothers' awareness about the state of their infants weaning diet was not related to the presence of anemia in the exclusively breast-fed infants. About 70% of the infants had started the weaning diet before age 6 months in all three groups, without any difference according to feeding patterns. Conclusion : The incidence of anemia was significantly higher in the breast-fed group than in the other infants. Many mothers of breast-fed infants with anemia also believed that their infants were taking sufficient weaning foods. Therefore, further education of the mothers about iron-rich weaning foods and the importance of iron intake during infancy is needed to prevent anemia, especially in breast-fed infants.
To understand the formation of initial gut microbiota, three initial fecal samples were collected from two groups of two breast milk-fed (BM1) and seven formula milk-fed (FM1) infants, and the compositional changes in gut microbiota were determined using metagenomics. Compositional change analysis during week one showed that Bifidobacterium increased from the first to the third fecal samples in the BM1 group (1.3% to 35.1%), while Klebsiella and Serratia were detected in the third fecal sample of the FM1 group (4.4% and 34.2%, respectively), suggesting the beneficial effect of breast milk intake. To further understand the compositional changes during progression from infancy to childhood (i.e., from three weeks to five years of age), additional fecal samples were collected from four groups of two breast milk-fed infants (BM2), one formula milk-fed toddler (FM2), three weaning food-fed toddlers (WF), and three solid food-fed children (SF). Subsequent compositional change analysis and principal coordinates analysis (PCoA) revealed that the composition of the gut microbiota changed from an infant-like composition to an adult-like one in conjunction with dietary changes. Interestingly, overall gut microbiota composition analyses during the period of progression from infancy to childhood suggested increasing complexity of gut microbiota as well as emergence of a new species of bacteria capable of digesting complex carbohydrates in WF and SF groups, substantiating that diet type is a key factor in determining the composition of gut microbiota. Consequently, this study may be useful as a guide to understanding the development of initial gut microbiota based on diet.

Compared to infant formula, breast milk is the best source of nutrition for infants; it not only improves the neonatal intestinal function, but also regulates the immune system and gut microbiota composition. However, probiotic-fortified infant formula may further enhance the infant gut environment by overcoming the limitations of traditional infant formula. We investigated the probiotic formula administration for one month by comparing 118 Korean infants into the following three groups: infants in each group fed with breast milk (50), probiotic formula (35), or placebo formula-fed group (33). Probiotic formula improved stool consistency and defecation frequency compared to placebo formula-fed group. The probiotic formula helped maintaining the level of secretory immunoglobulin A (sIgA), which had remarkably decreased over time in placebo formula-fed infants (compared to weeks 0 and 4). Moreover, probiotic formula decreased the acidity of stool and considerably increased the butyrate concentration. Furthermore, the fecal microbiota of each group was evaluated at weeks 0 and 4. The microbial composition was distinct between each groups, and the abundance of health-promoting bacteria increased in the probiotic formula compared to the placebo formula-fed group. In summary, supplementation of probiotic infant formula can help optimize the infant gut environment, microbial composition, and metabolic activity of the microbiota, mimicking those of breast milk.
Purpose: The purpose of the study was to describe growth and development of breast-fed infants and to depict experiences of breastfeeding mothers. Method: The data were collected from 145 infants and mothers participating in A Healthy Breastfeeding Infant Contest. The instrument used for this study was a self-report questionnaire completed by the participants and an evaluation record completed by the examiners. Results: The more specific results of the study are as follows: the weight of the infants was much higher than the Korean Standards. The height of infants was not significantly different from the Korean Standards except for 5 month old male infants. The results of Denver II showed all 145 infants were classified as normal. The breastfeeding experiences in mothers was as follows; 31.7% of the mothers breastfed for 5 months, 48.3% wanted to breastfed as long as the baby wanted. The mothers pointed out that the difficult problem in breastfeeding was insufficient breastfeeding room in public areas. What mothers want to know related to breastfeeding was, breastfeeding duration, time to begin solid food and recommended amounts, time to discontinue breastfeeding at sleep time and appropriate methods. Conclusion: Mothers' experience in breastfeeding was positive. We should provide mothers a comfortable place in public areas for breastfeeding. Based on the result of the study it's propose that health professionals must intervene in breast care during both antepartum and early postpartum periods.
A study was designed to assess the current status of infant feeding and weaning practice through an retrospective survey on feeding method, a period of weaning and various kinds of weaning food. Analysing a few influential environmental factors while assessing the level of knowledge today's mothers have on infant nutrition. The results are as follows: 1. As random samples for this study, a total of 516 mothers having infants under the age of 3 were surveyed. Among them, 235 were from Seoul and 281 were from Kyongi province (Yongin, Suwon, Bupyong, Poil, Kihung, Ansan(Chungbuk)). 2. Among the infants who fell under the category of normality (Kaup index $15{\sim}18$), the infants from Seoul area amounted to 60.7%, surpassing the percentage of the infants from Kyongi province, 41.9%. The percentage of the infants belong to a group of under nutrition (Kaup index <13) was relatively higher than that of the infants in a group of overnutrition (Kaup index >20). 3. 16.1% of mother surveyed were breast-fed, 54.6% were formula-fed and 29.3% were mixed-fed. The result indicated that the percentage of breast-fed infants of high-educated, working mothers were relatively lower than those of low-educated housewives. 4. Most of the respondents knew the significance or the necessity of supplementary food in terms of weaning. 5. 98.8% of those surveyed responded that the mother's adequate knowledge on weaning was necessary. 70.1% of them replied that they wanted to get various and in-depth information in printed materials such as books or other kinds of publications. They, also showed deep interest in recipe of weaning food. 6. The average period when those surveyed began weaning of their infants was $4.3{\pm}1.8$ months. The tendency of earlier weaning in 3 months was founded among 41.1% of them. About half of the respondents, 52.3%, started weaning of their infants in $4{\sim}6$ months. In overall, 93.4% of them set on weaning in less than 6 months after babies were born. The survey, in addition, revealed an interesting fact that earlier weaning of infants was shown in the group of high-educated mothers. 7. According to the study, finishing period of weaning was $13.3{\pm}5.4$ months on average. Only 38.9% of the respondents ended weaning of their infants in 12 months, the proper period recommended by renowned experts. In general, the infants on formula-feeding finished their weaning later than those on breast-feeding (p<0.05).
This study was conducted to investigate the weaning practice of 170 infants, aged 6 to 20 months, in Sockcho city Kangwon province. Informations on the infant feeding were obtained by interviewing mothers in three different pediatric clinics located in Sockcho. In this survey 40.4% of infants were breast-fed, while 44.1% of them were bottle-fed. Among subjects 75.9% of infants began to be weaned within 6 months. Among those who finished weaning aleady, 56.7% of infants fnished weaning 11 to 13 months. Sixty percent of mothers got the nutritional knowledge on infant feeding by the aid of cook book and child care book. Fruit juice was firstly introduced as infant food. The most favorite food for infants was fruit juices which were followed by soup, and e99 Pudding. Cereals were used frequently as infant foods while meat & fish, beans and vegetables were lesser used for infants. For the improvement of nutritional states of infants. nutritional education programmes and development of infant food is needed.
