Effects of different feeding patterns on physical and nutritional status of infants aged 6‒12 months / 上海预防医学

ObjectiveTo analyze the effects of different feeding patterns on the physical and nutritional status of children aged 6‒12 months， so as to provide reference for promoting scientific feeding and health development of infants and young children. MethodsChildren born between December 2019 and February 2020 and who had completed three follow-up visits at 6‒， 9‒ （8‒10 months） and 12‒ （11‒14 months） months old in all of the 13 communities of Minhang， Shanghai were selected. The subjects’ basic information was investigated by questionnaires. The indicators including feeding pattern， physical development （body weight， body length， head circumference） and nutritional status （the detection rate of overweight， obesity， low body weight， growth retardation， emaciation and iron deficiency anemia） were followed up in the outpatient department， with iron deficiency anemia only monitored at the 6‒ and 12‒ months old. According to different feeding patterns， the groups of 6‒ months old were divided into three groups of exclusive breast feeding （EBF）， mixed feeding （MF） and artificial feeding （AF）， while 9‒ and 12‒ months old were divided into MF and AF groups. The differences of basic information and follow-up results among the groups were analyzed. ResultsA total of 470 children were included， including 130 （27.66%）， 288 （61.28%） and 52 （11.06%） respectively in EBF， MF and AF groups at the 6‒ months old，and 319 （67.87%） and 196 （41.70%） in MF group at the 9‒ and 12‒ months old. There was no significant difference in the other follow-up results among the groups. The detection rate of iron deficiency anemia in 6‒ months old EBF （13.08%） was higher than that in MF group （5.90%） and AF group （1.92%） （χ2=8.40， P=0.010）， while it was still higher in 12‒ months old MF group （9.69%） than in AF group （2.92%） （χ2=9.68， P=0.002）. ConclusionThere is no significant difference in body weight，body length， head circumference， and the detection rates of overweight， obesity， low body weight， growth retardation and emaciation among the groups of different feeding patterns in the children aged 6‒12 months. The detection rate of iron deficiency anemia in the EBF and MF groups is significantly higher than that in the AF groups of children aged 6‒ and 12‒ months old.

Characteristics of immune function of full-term infants with different feeding patterns at the age of 3 months: a prospective cohort study / 中国当代儿科杂志

OBJECTIVES@#To explore the characteristics of immune function of healthy full-term infants at the age of 3 months, and to analyze the relationship of immune function with feeding pattern and sex.@*METHODS@#A total of 84 healthy full-term infants born in four hospitals in Beijing and Hohhot, China were prospectively recruited. Their feeding patterns remained unchanged within 4 months after birth. They were divided into a breast-feeding group and a milk powder feeding group according to their feeding patterns. At the age of 3 months after birth, peripheral venous blood samples of the two groups were collected to evaluate cellular immunity and humoral immunity and perform routine blood test. The laboratory indices were compared between infants with different feeding patterns and sexes.@*RESULTS@#Compared with the milk powder feeding group, the breast-feeding group had significantly lower proportion of T cell second signal receptor CD28, immunoglobulin M, and proportion and absolute count of neutrophils (@*CONCLUSIONS@#Sex has no significant effect on the proportion of lymphocyte subsets in 3-month-old full-term infants, but feeding patterns are associated with the proportion of CD28

Parents’ Knowledge and Children’s Feeding Patterns in Relation to Caries Experiences

@#This study aims to assess the association of parents’ knowledge, children’s feeding pattern, and other contributing factors with caries experience of a child. This was a cross-sectional study using a validated questionnaire of 145 children aged two to eight years old attending the Faculty of Dentistry, Universiti Teknologi MARA (UiTM), Malaysia. The questionnaires were given to the parents during their children’s dental visit in paediatric clinic and primary care. Dental caries was traced from the patient’s record in the Integrated Dental Records Management System (IDERMS) and clinical examination was done for those who did not have the dental record. Charting was recorded using dentition status and treatment need based on the 1997 World Health Organization (WHO) criteria. Data were analysed using the independent t-test and one-way ANOVA to examine the association of dental caries with two and three or more categorical variables respectively using SPSS 23.0. The study participants were 74 (51%) boys and 71 (49%) girls. The mean dmft score of the participants was 3.31 (4.36). Caries experience was statistically significant with the reason for first dental visit (p < 0.001), the age of the children discontinues bottle-feeding (p < 0.001), habits of leaving bottle-feeding while sleeping (p = 0.011), children wake up for milk at night (p = 0.050) and knowledge of parents on the effect of leaving bottle while sleeping (p = 0.037). Children feeding patterns and parents’ knowledge of the risk factors of dental caries were significantly associated with caries experience among children aged two to eight years old.

Se encontró relación significativa entre diversidad Alimentaria y la talla del niño

Introduction: Food diversity can be used to measure the quality of the feeding habits. It has a positive association with diet quality and constitutes an important factor to reach the nutritional requirements. Objectives: Assess the variability in feeding patterns of pre-schoolers living in Asunción, from families with high socioeconomic status and the relation with their nutritional status. Methodology: Observational, transversal in time, qualitative study. The researchers evaluated children from 2-6 years of age, from families with high socioeconomic status living in Asunción, from September to October of 2014, using antromopetric measures and two questionnaires applied in direct interview format: the first one with demographic data and the second one with a list of locally available food. The nutritional status and its relation with food diversity were assessed, measuring frequency. World's Health Organization's Software Anthro 3.2 was used for anthropometric evaluation. Results: In total, 67 children were included in the study, mainly female. 89,5% of the patient's mother had concluded tertiary education. 63% of patients were well-nourished and 31,5% had excess weight (overweight and obese). 19% were in risk of stumpting and 1,5% were in the range of stumpting. A total of 172 food varieties were found, distributed in 9 groups, the mean quantity of food varieties consumed by children was of 69,19 (CI: 95%, 63,79-74,59), ranging from 28 to 126 food varieties. Significant differences were not found in Body Mass Index and food diversity; but a statistically significant relation was found between food diversity and height. Conclusion: Low variability in feeding patterns was found in children with high socioeconomic status. There was a significant relation between food diversity and the child's height

Effects of three different ways of feeding on physical growth of low birth weight premature infants after discharge / 中国基层医药

Objective To investigate the effects of three different ways of feeding on the physical growth of low birth weight premature infants discharged from hospital.Methods 90 premature infants were selected.According to the different feeding methods,the infants were divided into A,B,C groups.Premature infants of A group were fed with preterm infants formula milk after discharge.B group received breast feeding.C group was fed with term infants formula milk.The physical growth at postnatal 30d,60d and 90d of three groups were observed and compared.Results The weight,length and head circumference of premature infants at postnatal 30d,90d in A group were better than those of B group and C group,the differences were statistically significant (all P ＜ 0.05).The weight,length and head circumference of premature infants at postnatal 60d in A group were similar to those in B group,the differences were not statistically significant (all P ＞ 0.05).The weight,length and head circumference of premature infants at postnatal 60d in A group and B group were better than those in C group,the differences were statistically significant (all P ＜0.05).Conclusion Compared with the breast feeding and traditional formula milk,formula milk for preterm infants is more conducive to the growth of premature infants to obtain nutrients,effectively promote the growth of premature infants,improve the prognosis and quality of life in preterm infants.

Oral Hygiene Practices and Bottle Feeding Pattern Among Children with Early Childhood Caries: A Preliminary Study

@#The purpose of this study was to assess the association of bottle feeding and oral hygiene practices with the severity of caries among 3 to 5-year-old children with Early Childhood Caries (ECC). This cross-sectional study was carried out on pediatric dental patients with ECC attending a public university hospital. The parents or guardians were interviewed for the bottle-feeding pattern and oral hygiene practices followed by a clinical dental examination of their children with ECC. Data analysis was done using Chi squared test. Out of 32 children, 69% had severe early childhood caries with mean dft of 8.88. In this study, 87.5% of the subjects had a history of bottle feeding, with 53.1% still being bottle fed at the time of study. Current bottle-feeding habit was found to be statistically significant with the severity of caries (p=0.021). Majority (69 %) of the children were introduced to tooth brushing only after 1 year of age. About 40% of the children consumed either pre-chewed rice and/or shared spoons or feeding utensils with their parents or siblings but there was no significant association with the severity of caries (p=1.00). Because of its association with ECC, prolonged bottle feeding is significantly associated with the severity of caries in our study population. Besides, vertical and horizontal transmission of bacteria was also a risk factor for ECC, but it did not show any significant association with severity of ECC.

Differences in ichthyofauna feeding habits among lateral lagoons and the river channel in a large reservoir / As diferenças nos hábitos alimentares da ictiofauna entre lagoas laterais e o canal do rio em um grande reservatório

In this study, we investigated differences in feeding habits of small-sized ichthyofauna among lateral lagoons and the river channel in a large reservoir. The study was performed in four lagoons and in one sampling site of the main channel in Rosana Reservoir, Paranapanema River, Brazil. The samples were taken in September and November of 2004 and in January, March, May, and August of 2005. Fish were sampled with a 7.5 m2 hand net. Five manual throws were made toward aquatic macrophytes stands. The sampling design favored the collection of small-sized fish fauna (juveniles/small-sized species). The stomach contents of 42 species were analyzed. A total of 183 different items were consumed by fish. These items were grouped in 11 food categories, which were used to classify fish into seven trophic guilds. Aquatic insects were consumed by 32 species and were the predominant feeding item. In the river, the most consumed items were aquatic insects, cladocerans, and phytoplankton, whereas in the lagoons aquatic insects, copepods, and cladocerans were the main items. By comparing each trophic guild, the number of insectivores, algivores, and zooplanktivores species was higher in the lagoons than in the river, and the opposite was found only for omnivore fish. Low niche width in all sites indicates high trophic specialization and low niche overlap between pairs of species. Fish assemblage in the lateral lagoons presents feeding habits distinct from those of the river species, indicating that the coexistence and high abundance of small-sized fish in the sampling sites are explained by their high feeding adaptability, which includes a tendency toward dietary specialization, low feeding overlap, and resource partitioning, along with different temporal resource uses.

O objetivo deste estudo foi avaliar a diferença no hábito alimentar da ictiofauna entre lagoas laterais e o canal do rio num reservatório de grande porte. O estudo foi realizado em quatro lagoas e um ponto no reservatório de Rosana, rio Paranapanema, Brasil. As amostras foram coletadas em setembro e novembro de 2004 e janeiro, março, maio e agosto de 2005. Foram realizados cinco arrastos manuais com uma rede de 7,5m2, junto aos bancos de macrófitas aquáticas. O desenho amostral favoreceu a coleta de peixes juvenis e espécies de pequeno porte. Os conteúdos estomacais de 42 espécies foram analisados. Um total de 183 diferentes itens foi consumido, que foram agrupados em 11 categorias alimentares. Sete guildas tróficas foram estabelecidas. Insetos aquáticos foram consumidos por 32 espécies de peixes, sendo o item alimentar predominante. O padrão alimentar da ictiofauna no rio foi diferente quando comparado as lagoas, como demonstrado na Análise de Correspondência Destendenciada. No rio, os principais itens alimentares foram insetos aquáticos, cladóceros e fitoplâncton, enquanto que nas lagoas os principais itens foram insetos aquáticos, copépodes e cladóceros. Comparando-se cada guilda trófica, o número de espécies de insetívoros, algívoros e zooplanctívoros foi maior nas lagoas do que no rio e o oposto foi encontrado somente para os onívoros. Foram registrados baixos valores de amplitude de nicho, indicando que as espécies apresentam alta especialização trófica, e baixa sobreposição de nicho trófico entre os pares de espécies. Finalmente, este estudo mostra que a coexistência e alta abundância das espécies de peixe de pequeno porte encontrada nas lagoas laterais são explicadas pela adaptabilidade alimentar, o uso temporal dos recursos pelos peixes e pela ampla disponibilidade de alimento existente nas lagoas.

Preliminary study of intestinal flora distribution in infants with different feeding patterns / 中华实用儿科临床杂志

Objective To investigate the characteristics of intestinal flora in infants with different feeding patterns.Methods Sixty-two cases of health infants(30-120 d)were divided into 4 groups according to their feeding patterns:breast feeding,imported powder milk feeding,domestic powder milk feeding and mixed feeding.Samples of their fresh feces in each group were collected and divided into sections equally:the bifidobacteria were isolated in anaerobic box and the number was counted for one section;for the other section,total DNA of intestinal flora was extracted and enterobacterial repetitive intergenic consensus (ERIC) fingerprints were amplified with the method of ERIC-PCR.After that,the specific bands observed in different groups were cloned and sequenced and alignmented.Results The colonies of bifidobacteria were more in breast feeding and mixed feeding groups[(9.10 ± 1.33) cfu/g;(8.62 ± 1.35) cfu/g]than those in domestic powder milk feeding and imported powder milk feeding groups[(7.62 ± 1.22) cfu/g;(7.32 ± 0.80) cfu/g,t =3.23,P ＜ 0.05];while there was no significant difference between breast feeding and mixed feeding groups,and between 2 powder milk feeding groups.Two specific bands were found from the ERIC fingerprints (A:1 100 bp mainly in breast feeding,domestic powder milk feeding and mixed feeding groups;B:1 000 bp mainly in imported powder milk feeding group).Sequencing and analysis of Basic Local Alignment Search Tool showed that homologous bacteria of A and B fragments were bifidobacterium longum.The encoding protein of A fragments might be related to the enzymes of carbohydrate metabolism,and B fragments were related to the enzymes of protein metabolism.Conclusions The colonies of bifidobacteria in intestinal tract are more in breast feeding and mixed feeding infants than those in formula feeding groups.The distribution of intestinal flora in domestic powder milk feeding infants is more similar to that of the breast feeding infants.

Feeding Pattern and Health Challenges of Nigerian Primary School Children in a Southeastern Urban Centre.

Aims: To document the feeding pattern of public primary school children, with emphasis on the staple diet and skipped meals; and the influence of diet and certain maternal demographic characteristics on their health and nutritional status. Study Design: This was a cross sectional descriptive study. Place and Duration of Study: The study was done in Onitsha, Anambra state, South East Nigeria between September and December, 2010 Methodology: This was a cross sectional descriptive study with multistage sampling of 804 children aged 6 to 12years from 12 public primary schools in the area. Selection was based on the age and gender distribution in each school. Verbal and written explanation was given to the parents/care givers who were invited to the schools to respond to interviewer administered questionnaires. Information was obtained on the feeding pattern of their children and maternal demographic characteristics. The children of those who responded, thereafter, had their heights measured and were assessed for clinically obvious morbidities. Information obtained on the age of respondents was verified from the schools’ registers. Data entry and analyses were done using Microsoft Office Excel 2007 and Statistical Package for Social Sciences (SPSS) version 16. Results: There were 406 males and 398 females with a male to female ratio of 1.02:1. Their staple diet was cassava and rice. An average of 2.5% of the children skipped one meal daily. Breakfast, which was the only meal that had a significant effect on stunted growth, (F=24.177, p value=0.002) was skipped by 2.2% of the children on the day of Original Research Article British Journal of Medicine & Medical Research, 4(27): 4542-4552, 2014 4543 interview. Only 1 of the children had a fruit within 24hours of the data collection. Fourteen percent of these children were stunted and the predominant morbidity observed was dermatophytosis. Most of the mothers (82%) were engaged in petty trading and menial jobs with 23.8% of them spending less than 500naira (3USD) on daily feeding. Maternal education and occupation were significantly associated with stunting in the children; p<0.05. Conclusion: Provision of at least 1 free school meal, preferably breakfast, is advocated for children in public primary schools. This will help to improve the daily nutritional content of the meals of these children who are obviously from poor homes.

Food and feeding pattern of Channa punctatus in two different habitats at Tarai region of Uttarakhand.

A comparative study was conducted for the food items and feeding pattern of Channa punctatus in pond environment and in reservoir of Tarai region in Uttarakhand state.Observation was made for body length, gut length, food and feeding frequency and qualitative and quantitative analysis of gut content.Both, body length and gut length were in higher side with a ratio of 1:2.1 for the natural fish stock of reservoir. Gut content mainly consists of crustacean, insects, mollusks, small fishes and semi-digested material. There was significant difference for the percent occurrence of the food items (p < 0.01) of natural stock of reservoir and pond reared stock. The study revealed that seasonal variability of natural food items in different habitats and their biological diversity put impacts on the biological needs in terms of food and feeding pattern of the same fish species.

Índice de masa corporal y tensión arterial al año de edad según peso al nacer, ganancia de peso y patrones de alimentación temprana / Body mass index and blood pressure at one year of age by birth weight, weight gain and early feeding patterns

Introducción. Las alteraciones en el crecimiento temprano se asocian con diferentes condiciones adversas en el curso de la vida. Objetivo. Analizar la asociación entre variación en el estado nutricional durante el segundo semestre de la vida y tensión arterial al año de vida, según condiciones al nacer y patrones alimentarios en una cohorte de niños sanos. Población y métodos. Estudio prospectivo de una cohorte de niños sanos seguidos entre los 6 y 12 meses de edad, entre octubre/2007 y marzo/ 08 en el Hospital Pedro de Elizalde. Se valoró peso y edad gestacional al nacer, peso, talla e índice de masa corporal (IMC) a los 6, 9 y 12 meses, duración de lactancia materna y tensión arterial a los 12 meses de edad. Resultados. Se estudiaron 120 niños que completaron el seguimiento. La variación en el valor estandarizado de IMC entre 6-12 meses de edad constituye el único predictor de IMC a los 12 meses (R2 0,12; Coef b 0,34; error estándar 0,11; p 0,006). La interacción entre duración de lactancia materna y bajo peso para la edad gestacional constituye el principal predictor de la variación de IMC (R2 0,11; Coef b -0,15; error estándar 0,04, p < 0,001). El incremento en una unidad estandarizada de IMC al año implica un incremento en 1,76 mmHg de tensión arterial diastólica. Conclusión. El aumento en el IMC se vinculó con menor duración de la lactancia materna. Tal variación se asocia con mayor IMC al año de edad y éste, a su vez, con mayor tensión arterial.

Introduction. Abnormal early growth patterns have been associated with overweight and other related diseases along the life course. Objective. To analyze the association between changes in growth patterns and nutrition status during the second semester of life and blood pressure (BP), according to weight for gestational age (GE), and early dietary patterns, in a sample of healthy children. Methods. Prospective study from a sample of healthy children followed between 6-12 months of age, between 10/07 and 3/08 at Hospital P. Elizalde. Gender, weight and gestational age at birth, weight, height and body mass index (BMI, WHO ref.) at 6, 9 and 12 months, length of breastfeeding, and blood pressure (BP) at 12 months of age were assessed. Results. One hundred twenty infants were follow- up. Variation in standardized BMI between 6-12 months of age is the main predictor of BMI at 12 months of age (R2 0.12; Coef b 0.34; error estándar 0.11; p 0.006). The interaction term between length of breastfeeding and small for gestational age is the main predictor of changes in BMI between 6-12 months of age (R2 0.11; Coef b -0.15; error estándar 0.04, p < 0.001). Each standardized unit increment in BMI implies an increase of 1.76 mmHg in diastolic blood pressure at one year. Conclusion. Length of gestation, birth weight and early feeding patterns are associated with weight gain during the first year of life, which is linked at the same time to BMI and BP. The positive change in BMI was associated with shorter duration of breastfeeding and this in turn to higher blood pressure at one year.

Feeding pattern of children under two years in some selected villages.

Objective: The present study was aimed to find out the feeding pattern of children less than two years of age in rural areas. Methodology: The study area consisting of three villages of Muradnagar Upazila under the district of Comilla. Families having children under-two years of age were included in the study. A total number of 54 families finally entered in the study. Respondents were interviewed using structured questionnaire regarding initiation of breast feeding of the new born, their breast feeding pattern and weaning of the children. Socio-demographic characteristics of the respondents were recorded. Data were presented as number and percentage. Results: Out of the 54 respondents 52 (96.3%) were mothers and 2 (3.7%) fathers. Of the total 50 (92.6%) respondents was housewife. Among 54 respondents 36 (66.7%) were in the age group of 18 to 25 years. Thirteen (24.1%) respondents were illiterate and among the rest 27 (50%) had primary level and 2 (3.7%) had bachelor level of education. Twenty six (48.1%) respondents said newborns were given breast milk first and rest 28 (51.9%) mentioned about giving of honey, cow’s milk and sweet water made of sugar or sugar product. Twelve (22.2%) mothers started breast feeding within 15 minutes after birth, 28 (51.9%) after 1 hour or more. Twenty one 21 (38.9%) had given exclusive breast feeding to the children for six months and 33 (61.1%) given additional stuff during that time. Thirty (55.6%) mothers started weaning before reaching 6 months of age, 13 (24.0%) between 6 months to 12 months and 1 (1.9%) started after 12 months. Commonly used weaning foods were rice, shuzi, khichuri, cow’s milk, infant formula, fish, egg, meat, honey, vegetables and fruits especially banana. Conclusion: The data suggest wide range of variability still exists in allowing colostrums to the newborn, breast feeding itself and also weaning practice.

A study on the incidence of anemia according to feeding patterns and the status of weaning diet / 소아과

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.

A comparative study on iron deficiency anemia based on feeding patterns of nine-month-old infants / 소아과

PURPOSE: This study was conducted to evaluate the red cell indices and frequency of iron deficiency anemia based on the feeding patterns of nine-month-old infants. METHODS: Blood tests were performed on 253 nine-month-old infants, who visited Il Sin Christian Hospital for health checkups from January to December 2007. Their parents answered telephonic questions regarding their feeding patterns and weaning foods. RESULTS: Three infants groups were created according to feeding patterns before they started weaning foods. One group was exclusively breast-fed (48.6%), another had mixed feeding (27.3%), and the third had artificial milk feeding (24.1%). Red cell indices (hemoglobin, hematocrit, MCV, MCH) of the breast-fed group were comparatively lower than those of the other two groups (P<0.05). Twenty-five infants (9.9%) were diagnosed with iron-deficiency anemia. According to feeding patterns, the frequency of anemia was highest in the breast-fed group. Six infants who started weaning foods before six months of age (113 infants) were diagnosed with iron-deficiency anemia (5.3%), and nineteen who started after six months of age (140 infants) were diagnosed with iron-deficiency anemia (13.6%). CONCLUSION: When nine-month old infants visit hospitals for health check-ups, pediatricians must consider their feeding pattern and weaning foods histories, and then recommend screening blood tests for iron-deficiency anemia.

Effects of the 8-week Resistance Exercise on Body Composition, Serum Hormone Profiles and Feeding Patterns of Obese Females

This study was designed to investigate the effects of 8-week resistance exercise by using dumbell on the body composition, serum hormone profiles and feeding patterns in young and healthy female students with over 30% of body fat, aged 22 years in Masan, Korea. The subjects were all six, performed successfully the entire exercise-program. Anthropometry, serum lipid and neurohormone profiles of subjects were analyzed at 0, 4 and 8 weeks after exercise. And also their food and nutrient intakes were self-reported by 3-day record and food frequency questionnaire. Triceps skinfoldthickness of the subject students significantly reduced after the exercise to 46% less than before (p < 0.002). The serum concentrations of leptin, insulin and catecholamine appeared to decrease steadily, but not significantly. Total protein in serum increased significantly (p < 0.05), and Na (p < 0.005), K (p < 0.001) and Fe (p < 0.058) concentrations increased remarkably within the normal range. The 8-week resistance exercise tended to induce fiber consumption (p < 0.089) of subject students and changed the P/M/S ratio changed into the desirable way from 0.8 : 1 : 1 to 1 : 1 : 1, and that of n- 6/n-3 PUFA from 11 : 1 to 6 : 1. After taking exercise, the intake frequency of cookies (p < 0.058) and raymeun (p < 0.085) decreased, but finally this feeding pattern returned to the way as before even though at marginal significance. Consequently the resistance exercise may induce the desirable changes of body fat and improve serum lipid profiles and feeding patterns in young obese females.

A Comparative Study of Red Blood Cell Indices and Anemia by Feeding Patterns

PURPOSE: Iron-deficiency anemia is the most common nutritional deficiency in young infants. This study was designed to determine feeding patterns in infants, and determine a correlation between feeding patterns and incidence of anemia. METHODS: This study was conducted by taking blood tests (hemoglobin, hematocrit, and red cell indices) by venipuncture with the electronic counters from 221 infants aged 9-12 months old, who came to Well Baby Clinics in the Department of Pediatrics, Seoul Sacred Heart Hospital for a health check-up. Their mothers answered a questionnaire regarding their feeding patterns. RESULTS: The 221 infants aged 9-12 months, were divided into three groups, i.e. infants who were exclusively breast-fed(group A=6.8%), those who had been given mixed feeding or breast milk for 2 months and then switched to artificial formula milk(group B=22.6%), and those who had been given artificial formula milk since birth(group C=70.6%). Of the 221 infants, 7 infants(3.2 %) were found to have iron deficiency anemia. Infants with anemia comprised 20.0%(3/15) of group A, significantly more than the 2.0(1/50) of group B and 1.9%(3/156) of group C(P<0.005). CONCLUSION: The incidence of iron-deficiency anemia was 3.2%, which was lower than previous reports, as 93.2% of the infants studied were from middle-class families. Seven infants with iron deficiency anemia were found to have been insufficiently fed with iron-rich weaning foods. Thus, studying the feeding patterns of infants is highly predictive of their risk for anemia. Therefore, regular blood tests on infants at high risk for anemia is recommended, as well as supplementary feeding of iron-fortified foods.

Pre-exercise rather than post-exerclse intake of a large meal enhances liver glycogen sparing during endurance exercise in rats / 体力科学

We investigated the effects of feeding a large meal to female rats (n = 66) just before or just after voluntary wheel running on energy metabolism during a final endurance exercise test. The rats were divided into three groups ; one fed a large meal just before exercise (BE), one fed a large meal just after exercise (AE), and one fed <I>ad libitum</I> (AD) . The rats were allowed to run voluntarily from 20 : 00 to 07 : 00 h. The BE group were given a large meal (more than 12 g) between 19 : 00 and 20: 00 h and a small meal (3 g) between 07 : 00 and 08 : 00 h. The AE group were given a large meal (more than 12 g) between 07 : 00 and 08 : 00 h and a small meal (3 g) between 19 : 00 and 20 : 00 h. After 4 weeks, 6 rats in each group were sacrificed at 22 : 00 h, and 12 rats in each group were sacrificed after 30 min starting from 22 : 00 h at 15 m/min (n=6) or 35 m/min (n=6) on a rodent treadmill (0° grade) . Four rats in each group were sacrificed after 30 min starting from 22 : 00 h at rest on the treadmill as a control. The plasma free fatty acid (FFA) and glycerol concentrations increased significantly during low-speed exercise in the AD group, and during higher-speed exercise in all groups. The liver glycogen concentration was significantly greater in the AE group than in the other groups at rest, and decreased significantly during exercise at both speeds in the AD group, but not in the BE and AE groups. The gastrocnemius muscle glycogen concentration was decreased significantly during exercise at both speeds in the AD group, and at high speed in the BE and AE groups.<BR>These results indicate that intake of a large meal just after exercise can store a high level of liver glycogen at the beginning of exercise than <I>ad libitum</I> feeding or large meal intake just before exercise, and expend plasma FFA in muscle during exercise compared with <I>ad libitum</I> feeding. This suggests that large meal intake just after exercise contributes to improvement of metabolic capacity in endurance exercise with enhanced liver glycogen sparing.

THE RELATIONSHIP BETWEEN THE DIET AND THE GROWTH OF INFANTS DURING THE WEANING PERIOD (6-18 MONTHS) / 营养学报

The growth curves and diet of 185 babies in rural area near Beijing from 6 months to 18 months old have been studied. Infants were divided into 3 groups according to their diet taken:(1) 89 babies had breast milk only;(2) 66 babies took more than 250g animal milk per day besides breast milk;(3) 30 babies who did not have breast milk and only animal milk was taken. All the babies were gradually transferred to an ordinary cereal based diet during the weaning period. To half of them a soybean and cereal based formula fortified with minerals and vitamins was supplied, which would provide 6.6g protein and 141 kcal and some other nutrients per day.The results showed that the growth curves of body weight and height of children were much better than the data obtained in 1975, but still lagged behind that of the urban children, especially for the body weight. The weight curves of the babies who took animal milk seemed higher than the other groups. Female babies who were fed with breast milk and supplemented with the weaning food have a better weight and height curves than non-supplemented ones, but this was not seen in males. The hemoglobin contents of the babies who took animal milk when they were 18 months old were lower than that of the 6 months old, but there were no differences in the breast milk groups, and the lowering of the hemoglobin level in the animal milk groups could be corrected by adding weaning food in the diet. When the babies were 6 months old, 39.3% of them had a hair zinc content below the lower limit of the normal range, and it became to 47.6% when they were 18 months old. So zinc deficiency of the babies were present in this local area, and it should be fortified into the weaning food.
