This study was aimed to evaluate any influence of environmental factors associated with feeding on infants' growth. One hundred infants(62 males and 38 females) aged 4-9 months were measured for length and were weighed. Their mothers were interviewed using questionnaires including general and environmental characteristics and maternal feeding attitude, ideal body habitus, infant's food behavior, and infant's food behavior, and infant's temperament. A further study was conducted on 29 infants at the time their ages reached 12 months. Their dietary intakes were assessed, and blood hemoglobin and serum ferritin concentrations were measured. Z-scores of weight-for-age(WAZ) and Z-scores of height-for-age(HAZ) of 4-9 month- old infants were not correlated with age, education level, income, weight, and height of their parents. Formula-fed infants had significantly lower WAZ and body mass index (BMI) than those of breast fed infants. WAZ was significantly correlated with maternal feeding attitude, but not with ideal body habitus, infant's food behavior or infant's temperament. WAZ of 12-months after birth because of supplementary foods introduced from 6 months of age. WAZ and BMI were positively correlated with blood hemoglobin concentration. Therefore, to ensure proper growth of infants, efforts should be given to postental factors such as breast-feeding, maternal feeding attitude, adequate iron status as well as prenatal factors.

The longitudinal changes in the transitional milk yields of Korean lactating women(14 primiparae, 11 multiparae) have been studied by test-weighing method in the part of Kangwon Province form 7 day to 15 days postpartum. The transitional milk yields at 7, 10, 15 days postpartum were 531$\pm$148,598$\pm$156 and 639$\pm$169g, respectively. The mean milk yield was 589$\pm$162g from 7 to 15 days postpartum. The transitional milk yields between primiparae and multiparae appeared not significantly different but significantly different between mothers of boys and girl(p<0.05). The distribution of individual transitional milk yields were found 550-649g(28.0%), 450-549g(24.0%), 650-749g(13.3%) and 750-849g(13.3%). The transitional milk yields were not affected by mother's age, weight gain during pregnancy, gestational period and infant's weight at birth but affected by maternal height(p<0.05). Maternal weight reduction during the lactation had no correlation with the transitional milk yeilds.

The longitudinal changes on human milk intake of exclusively breast-fed infants(boys=15, girls=12) from 0.5 to 6 months after parturition have been studied by test-weighing method in Cheongju and Anseong area. Infant milk intake per day tended to increase during lactation. The mean intake at 0.5, 1, 2, 3, 4, 5, and 6 months were 532, 695, 734, 756, 785, 767, and 710g, respectively. The average intakes were 752 and 660g for boys and girls, respectively. The overall mean intake was 711g/day. The milk intake between boys and girls at 1, 2, 4 months, and mean value was significantly different(p<0.05). Infant milk intake had a significant positive correlation with human milk volume of lactating women, but no correlation with maternal age, weight before delivery, height, and birth weight.

Purpose: Pregnancy in transplanted mother is considered as a high-risk pregnancy, and significant incidences of prematurity and low-birthweight(LBW) infants have been reported. The objective of this study is to examine the outcome of pregnancy in transplanted mothers and to evaluate the current growth status in their children. Patients and Methods: We retrospectively reviewed 54 pregnancies in 40 kidney recipients until June 1999. Outcomes of pregnancy were reviewed and assessment of the current growth status in children was performed. Results: 54 pregnancies in 40 recipients were identified; 22 ended in termination of pregnancy because of unwanted pregnancy or therapeutic purposes. And of the other 32, 29 livebirths resulted in 28 recipients. The mean age of conception was $30.3{\pm}3.8$ years, with a mean interval from transplantation to conception of $35.9{\pm}23.2$ months. All patients were maintained on immunosuppressive regimens. Incidence of drug-treated hypertension(HTN) prior to pregancy was $52\%$, HTN during pregnancy, $48\%$; preeclampsia, $41\%$; urinary tract infection, $48\%$; oligohydramnios $4\%$; and no rejection during pregnancy and up to 3month post delivery. Of the 29 liveborn infants, prematurity(<37wk) occurred in $52\%$, LBW(<2500g) in $62\%$, VLBW(<1500g) in $7\%$ and $48\%$ born intrauterine growth retardation(IUGR). Mean gestational age was $36.3{\pm}3.0\;wk$; a mean birthweight, $2.23{\pm}0.6\;kg$; a mean birth-height, $45.1{\pm}3.6cm$. Current mean height standard deviation score (height SDS) was $0.29{\pm}0.91$ and mean weight SDS was $0.62{\pm}1.34$. Only one child($4\%$) under 1 year of age was below 10 percentile in height. Most of children had no medical problems except for 4 children; cleft palate(1), tuberous sclerosis(1), essential hematuria(1), and one child expired due to sepsis. Conclusion: This study showed similar incidence of premaure birth($57\%$) and low birth weight infants($62\%$), but lower incidence of spontaneous abortion($5.6\%$) was observed and compared to other studies. Postnatal growth in majority of children($96\%$) achieved catch-up growth before 1 year. Present study supports a more optimistic view of pregnancy in renal transplant mother and normal growth in their children.

This was a prospective cohort study of 976 infants from birth to 12 months of age. Infants were fed breast milk, goat infant formula, cow infant formula, or a combination of formula and breast milk during the first 4 months of age. Data on type of milk feeding and infant growth (weight and height) were collected at birth and at 4, 8, and 12 months during routine clinical assessment. The number and consistency of bowel motions per day were recorded based on observational data supplied by the mothers. Infants fed breast milk or goat or cow infant formula during the first 4 months displayed similar growth outcomes. More of the infants fed cow infant formula had fewer and more well-formed bowel motions compared with breast-fed infants. The stool characteristics of infants fed goat formula resembled those of infants fed breast milk.

This study was conducted to investigate the bone mineral density (BMD) and the anthropometric measurements, socioeconomic factors, family history of osteoporosis and other environmental factors affecting BMD in children. One hundred sixty children (80 males, 80 females) in second grade of elementary school in Seoul were recruited; the mean age was 7.7 $\pm$ 0.47 years. Bone mineral density was measured in the lumbar spine (LS), femoral neck (FN), femoral trochanter (FT), and Ward's triangle (WT) by Dual Energy X-ray Absorptiometry (DEXA). Socioeconomic factors, family history of osteoporosis, and other environmental factors were assessed by questionnaire. Bone mineral densities of LS, FN, FT, and WT were 0.677, 0.637, 0.618, and 0.658 g/$\textrm{cm}^2$. BMD of boys was higher than that of girls (LS: 0.685 vs. 0.669, FN: 0.660 vs. 0.614, FT: 0.632 vs. 0.604, WT: 0.678 vs. 0.639 g/$\textrm{cm}^2$). Anthrometric measurements (height, weight relative body weight, circumference of waist and hip) were positively correlated with BMD. With increasing family income, BMD of LS was significantly lowered, and negative correlation was observed between mother's age at birth of subject and the BMD of FN. And the BMD of children with a family history of osteoporosis was significantly lower. However BMDs were not different by educational level of parents, family pattern, delivery term, birth weight, and type of feeding. Further studies are needed to clarify the factors affecting BMD of children and earlier age, included infants and even prenatal life. If any association is revealed and persist until the attainment of peak bone mass, osteoporosis prevention programs are needed to be start very early in the life cycle.

This study was designed to investigate the relationships between children's physical growth and health and their raising conditions and to find out the important conditions to improve their physical growth and health. The rasing conditions were classified into three major parts; i. e., family conditions, conditions of nutrition up-taking, and conditions of rest or sleep and exercise or play. Then, the questionnaire including the items to survey these three areas of raising condition and the items to evaluate the health status were given to children' mothers or fathers and filled up by them. The data of their 4 anthropometric measures; body weight, stature, sitting height and chest girth, were also collected from their latest records of health examination. The data of health status were converted to health scores representing 6 domains of health; digestive organs, respiratory organs, auto-nerve systems, fatigue, others and health as a whole. Then, correlations of raising conditions were determined with four antropometric measures and 6 health scores as criterion variables. Then, number of families to live together, and child's birth order in the domain of family conditions, habits of unbalanced diet, eating frequency of eggs, fruits, green and yellow vegetables, light colored vegetables, milk products in the domain of nutrition up-take, and the time for study at home, the place for play, the number of friends to play with together, the hours for playing out of door, the hours for playing sports, and the hours to move their body for assisting house keeping were picked out to investigate their relationships with physical growth and health status. Then, their habits of unbalanced diet and eating frequency of eggs, green or yellow colored vegetables, and milk products were found more influential conditions and more over, birth order, the time for study at home, the time to play out of door showed moderate degree of connection with physical growth and health status in early childhood.

Russell-Silver syndrome is a type of intrauterine growth retardation, characterized by short stature noted at birth, hemiatrophy or asymmetry, variation in sexual development and other abnormalities, including cafe-aulait pigmentation and clinodactyly. Facial features commonly associated with this syndrome are a small triangular face, decreased facial height, down-turned corners of the mouth(shark's mouth), a small mandible, and occasionally asymmetry. The major intra-oral features of the syndrome that have been reported are a high-arched palate, delayed tooth eruption, microdontia, hypodontia, and crowding. These cases were diagnosed at birth as Russell-Silver syndrome by clinical features such as prenatal growth retardation, short stature, low body weight, et al., and have been treated with growth hormone. The purpose of this paper is to report the dental findings of two patients and review the pertinent literature through the two cases.

Sotos syndrome (SS, OMIM 117550) is characterized by prenatal and postnatal overgrowth with multiple congenital anomalies. However, there have been few cases of growth retardation caused by renal failure from infancy. We report a case of dysplasia of the bilateral kidneys with renal failure and poor postnatal growth. A 2-month-old boy visited the emergency room owing to poor oral intake and abdominal distension. He was born at the gestational age of 38 weeks with a birth weight of 4,180 g. After birth, he had feeding difficulty and abdominal distension. Upon physical examination, his height and weight were in less than the 3rd percentile, while his head circumference was in the 50th percentile on the growth curve. He also showed a broad and protruding forehead and high hairline. Blood laboratory tests showed severe azotemia; emergent hemodialysis was needed. Abdominal ultrasonography revealed bilateral renal dysplasia with multiple cysts and diffuse bladder wall thickening. A posterior urethral valve was suggested based on vesicoureterography and abdominal magnetic resonance findings. Results of a colon study to rule out congenital megacolon did not reveal any specific findings. The conventional karyotype of the patient was 46, XY. Array comparative genomic hybridization study revealed a chromosome 5q35 microdeletion including the NSD1 gene, based on which SS was diagnosed. We describe a case of SS presenting with end stage renal disease due to posterior urethral valve. The typical somatic overgrowth of SS in the postnatal period was not observed due to chronic renal failure that started in the neonatal period.

Background: Acute respiratory infections (ARIs), especially pneumonia, remain a major cause of infant mortality worldwide. In Indonesia, pneumonia is the second most common cause of infant and toddler deaths. Exclusive breastfeeding and basic immunization can protect infants and children from contracting pneumonia. Purpose: Our goal was to assess the risk factors for childhood pneumonia in regions with a high prevalence of pneumonia in Indonesia. Methods: This case-control study was conducted between March and April 2019. A total of 176 infants and toddlers aged 10-59 months were enrolled and selected from among patients who visited the community health center. Cases of pneumonia were diagnosed clinically based on the World Health Organization guidelines, and the control was nonpneumonia. Results: The risk factors for the diagnosis of pneumonia included no or nonexclusive breastfeeding (odds ratio [OR], 7.95; 95% confidence interval [CI], 3.52-17.94), incomplete basic immunizations (OR, 4.47; 95% CI, 2.22-8.99), indoor air pollution (OR, 7.12; 95% CI, 3.03-16.70), low birth weight (OR, 3.27; 95% CI, 1.19-8.92), and a high degree of wasting (OR, 2.77; 95% CI, 1.06-7.17). Other variables such as nutritional status (height-for-age z score), age, sex, and educational status of the mother were not risk factors for pneumonia. Conclusion: No or nonexclusive breastfeeding, incomplete basic immunizations, indoor air pollution, a history of low birth weight, and severe malnutrition were risk factors for childhood pneumonia. Breastfeeding was the dominant factor, while sex modified the relationship between exclusive breastfeeding and the incidence of pneumonia.
