Impacto del abandono de la lactancia materna exclusiva sobre la salud de los lactantes / Impact of exclusive breastfeeding withdrawal on the health of babies

Introducción: El abandono de la lactancia materna es uno de los problemas que enfrenta el Sistema Nacional de Salud en Cuba por las consecuencias desfavorables que representa para la salud de los lactantes. Objetivo: Identificar la relación entre el abandono de la lactancia materna exclusiva y las afectaciones en la salud de los lactantes. Material y Métodos: Se realizó un estudio descriptivo, retrospectivo de corte transversal, en 105 lactantes del Policlínico Aleida Fernández Chardiet nacidos en 2019, cuyas madres dejaron de utilizar la lactancia materna exclusiva antes del sexto mes. Las variables utilizadas fueron edad materna, tiempo de duración de la lactancia materna exclusiva, las enfermedades más frecuentes diagnosticadas en el niño y la necesidad de ingresos hospitalarios. Se aplicó la prueba no paramétrica de independencia Chi Cuadrado para demostrar la relación entre variables. Resultados: Predominó el abandono de la lactancia materna exclusiva antes de los 3 meses y no se encontró relación estadísticamente significativa entre esta y las afecciones más frecuentes de los lactantes (las IRA en 40 por ciento y las EDA en 23,8 por ciento). El 55,2 por ciento necesitó ingreso hospitalario antes del sexto mes y la relación con el abandono precoz de la lactancia materna exclusiva fue estadísticamente significativa. Conclusiones: El abandono precoz de la lactancia materna exclusiva afecta la salud de los lactantes y aunque las afecciones no tuvieron una relación estadísticamente significativa con aquella sí tienen una elevada frecuencia en estos niños de tan corta edad(AU)

Introduction: Breastfeeding withdrawal is one of the challenges faced by the Cuban National Health System due to its adverse consequences on the health of babies. Objective: To identify the relationship between exclusive breastfeeding withdrawal and health disorders in babies. Material and Methods: A descriptive, retrospective, cross-sectional study was carried out on 105 breastfed babies from "Aleida Fernández Chardiet" Policlinic who were born in 2019 and were precociously weaned from exclusive breastfeeding before the sixth month. The variables used were: maternal age, duration of exclusive breastfeeding, most frequent diseases diagnosed in the child, and need for hospital admission. The chi-squared non-parametric independence test was used to show the relationship among variables. Results: Exclusive breastfeeding withdrawal before the third month was predominant (71, 4 percent); the most frequent diseases diagnosed were respiratory diseases and diarrheas (40 percent and 23,8 percent, respectively); about half the babies required hospital admission (55,2 percent) before the sixth month; the relationship with early withdrawal of breastfeeding was statistically significant. Conclusions: Early withdrawal of breastfeeding has negative effects on the health of babies. Although the illnesses did not have a statistically significant relationship with it, a high frequency of their incidence was found in such young babies(AU)

The correlations between gut microbiota of Muslim Thai lactating women and their dietary intake and gut microbiota of breastfed infants

@#Introduction: Foods and nutrients are essential not only for human health, but also for the balance of gut microbiota. This research aimed to correlate the gut microbiota of lactating women with their food/ nutrient intakes, as well as with their infants’ gut microbiota. Methods: A cross-sectional study was conducted in 27 pairs of mothers and their exclusively breastfed infants. For lactating women, the dietary assessment was conducted by 24-hour recall, and food groups were assessed following the Food and Agriculture Organization’s guidelines, while nutrient intake was analysed using INMUNCAL V3 programme. Gut microbiota of mothers and infants were measured in stool samples using fluorescent in situ hybridisation technique. Results: It was found that energy intake of mothers was only 66% of the recommended Thai Dietary Reference Intakes (DRIs). Most micronutrient and dietary fibre intakes were below the Thai DRIs. Vitamin A (VA)-rich fruits and vegetables food group correlated positively with Lactobacillus species (spp). The association between gut microbiota and nutrient intake of lactating women showed that total protein, phosphorus, and VA were positively correlated with Bifidobacterium spp.; while β-carotene and vitamin C were also positively correlated with Lactobacillus spp. In contrast, consumption of eggs and calcium correlated negatively with Clostridium spp./ Enterobacter spp. Bifidobacterium spp. and Lactobacillus spp. of lactating women and breastfed infants showed strong correlations. Conclusion: Food and nutrient intakes of lactating women were correlated with their Clostridium spp./Enterobacter spp., Bifidobacterium spp. and Lactobacillus spp. Furthermore, Bifidobacterium spp. and Lactobacillus spp. of mothers and breastfed infants showed strong correlations.

Prevalence of vitamin D deficiency in exclusively breastfed infants at a tertiary healthcare facility in Nairobi, Kenya

ABSTRACT Objective: To determine the prevalence of vitamin D deficiency (VDD) in exclusively breastfed infants at the Aga Khan University Hospital Nairobi, Kenya (AKUHN). The relationships between 25-hydroxyvitamin D; 25OHD, parathyroid hormone (PTH), maternal vitamin D supplementation, and sunlight exposure were also determined. Subjects and methods: Blood from 98 infants was assayed for 25OHD, calcium, phosphate, and PTH. Socio-demographic and clinical characteristics were analyzed using descriptive statistics and inferential analysis (p < 0.05). Results: The prevalence of VDD (25OHD <12 ng/mL), vitamin D insufficiency (VDI, 25OHD 12-20 ng/mL) and vitamin D sufficiency (VDS, 25OHD >20 ng/mL) was 11.2% (95% CI 8.0%-14.4%), 12.2% (95% CI 8.9%-15.5%), and 76.5% (95% CI 72.3%-80.8%) respectively. There was no difference in the mean age, head circumference, length, or weight of infants in VDD, VDI, and VDS groups. PTH was elevated when 25OHD was <12 ng/mL and normal when 25OHD was between 12-20 ng/mL. 25OHD and PTH were normal in infants whose mothers received vitamin D supplements. Infants who received <30 minutes/day of exposure to sunlight were 5 times more likely to have VDI than infants who received ≥30 minutes/day (p = 0.042). Conclusions: The prevalence of VDD in exclusively breastfed infants at AKUHN is low. The current national policy that recommends exclusive breastfeeding of infants in the first 6 months of life appears to be effective in staving off vitamin D deficiency but those infants with < 30 minutes sunlight exposure may benefit from low dose supplemental vitamin D during times of low sunlight exposure.

Impact of infant & young child feeding & caring practices on morbidity

Background: Around 5.9 million children still die every year before reaching their fifth birthday. Child morbidity and mortality due to preventable causes remains high in developing countries. Aim & Objective: To find out the relationship of morbidity with child rearing practices and sociodemographic characteristic. Material and Methods: To cover a sample size of 400 in urban health center area population under 5 children every alternate family was selected by systematic random sampling from the total of 1867 registered families at urban health center. The data was obtained by the interview of mothers and examination of children using predesigned and pretested Questionnaire. The data thus collected, was first coded and then transferred to a master chart on Microsoft Excel sheet, from which distribution as well as co-relation tables were prepared, analyzed and statistically evaluated by SPSS version 20.0.Result: In the present study, the overall fortnightly incidence of morbidity among under 5 children was found to be 65.3% (boys – 64.2%, girls – 66.5%). Exclusive breastfeeding (p < 0.001); time of initiation of breastfeeding (p < 0.001); complementary feeding (p < 0.05) and hand washing practices (p < 0.001) are statistically significant predictors of child morbidity Conclusion: We need comprehensive child health care programme having all three promotive, preventive and curative services.

Asymptomatic hypernatremia in exclusively breastfed neonates

Background: The aim of study was to identify the asymptomatic hyparnatremia in exclusively breastfed neonates and to study the factors associated with it.Methods: A cross-sectional study was conducted from November 2010 to October 2012 in Jawaharlal Nehru Medical College and Hospital, A. M. U., Aligarh. Consecutive term appropriate-for-gestational age and asymptomatic neonates who were exclusively breastfed since birth were enrolled.Results: A total of 1360 term neonates were screened, out of which 145 neonates in each early and late neonatal group were enrolled. Prevalence of hypernatremia in 290 patients was 4.48% (n=13) with mean serum sodium level of 156.6'5.5 mmol/L, ranging from 151 to 167 mmol/L. It was 16 times more common in early compare to late neonates (adjusted odds ratio=16.074, P=0.001), 6 times more common in primi mothers (adjusted odds ratio=6.037, P=0.010) and 7 times more common during summer season (May-August) (adjusted odds ratio=6.566, P=0.017). Other variables like sex, mode of delivery and blood urea levels do not show significant association with hypernatremia. There was a significant positive correlation of serum sodium level with blood urea (r=0.123, P=0.037) and serum creatinine levels (r=0.157, P=0.007), and a negative correlation with blood sugar levels, but it was not significant (r=-0.072, P=0.224).Conclusions: The prevalence of hypernatremia in exclusively breastfed term asymptomatic neonates is 4.8%, and is more common in early neonatal period, in summer season and in babies born to primi mothers. There was a significant positive correlation of serum sodium with blood urea and creatinine levels.

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.

Growth Pattern of Exclusively Breastfed Babies in Urban Affluent of Bangladesh

Objective: To find out the growth in the exclusively breastfed babies of the affluent mothers and to compare the figures with those of the children in the industrialized countries. Methods and materials: Fifty-three babies were selected in 1 year time period for this cross-sectional study under 6-month of age with prefixed criteria, such as exclusively breastfed and not fed with any formula feeding. Recommended schedule of immunization (EPI) was followed to weigh and measure for supine length. Data were analyzed in PC through SPSS and some calculations were done in calculator too. Place and time of work: Data were collected from August 2011 to June 2012 in the Pediatrics Department of Bangladesh Medical College Hospital and the Researcher’s Chamber at Dhanmondi, Dhaka. Results: The data of developed countries showed that in first 3-month of age, children grow in weight 30 gm/day and in length 3.5 cm/month, followed by weight gain of 20 gm/day and linear growth 2 cm/ month in next 3-6 months. Our babies could be compared to those figures, with 33.54 gm/day in the weight gain and 4.17 cm/month in linear growth in the first 3 months. The average weight gain during the next 3 months (3-6 months of age) was 22.3 gm/d and linear growth for this period was 2.12 cm/month. Conclusion: Babies of our country in well-off families can grow optimally in comparison to the growth of the babies in the industrialized countries, or even can exceed, if they are exclusively breastfed and brought up ensuring immunization and follow up in educated mothers.

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.

Rede e apoio social e práticas alimentares de crianças no quarto mês de vida / Social network, social support and feeding habits of infants in their fourth month of life

O objetivo deste trabalho foi investigar a associação entre rede e apoio social e as práticas alimentares de lactentes no quarto mês de vida. Estudo seccional com 294 crianças selecionadas em 4 Unidades de Saúde do município do Rio de Janeiro/RJ/Brasil. Para avaliar as práticas alimentares foi aplicado um recordatório 24h, para medir rede social foram feitas perguntas relacionadas ao número de amigos e parentes "com quem a mãe pode contar" e participação em atividades sociais. A versão em português da escala empregada no "Medical Outcomes Study" foi utilizada para aferir apoio social. Análises foram realizadas por meio de modelos de regressão logística multinomial. A maioria dos lactentes recebeu leite de peito (84%), mas apenas 16% o receberam exclusivamente. Crianças filhas de mães com menor número de parentes com quem contar e com baixo apoio social apresentaram maior chance de estarem em aleitamento artificial em relação ao aleitamento materno exclusivo (AME). Destaca-se a necessidade de integrar os membros da rede social da mulher à atenção pré-natal, ao parto e puerpério para prover o apoio social que atenda as suas necessidades e, assim, contribuir para manutenção do AME.

The scope of this study was to investigate the association between the social network, social support and the feeding habits of infants in their fourth month of life. A cross-sectional study was conducted among 294 children selected at 4 Primary Health Care Units in Rio de Janeiro/ Brazil. A 24-hour dietary recall was applied to the mothers to evaluate the feeding habits. Questions related to the number of people upon whom the woman can rely were asked as well as their participation in social activities to measure the social network. The scale in the Medical Outcomes Study was used to measure social support. The analysis was based on multinomial logistic regression models. Most of the infants (84%) received breast milk, but only 16% were exclusively breastfed. Children whose mothers had a small number of relatives to rely on and with low social support were more likely to be bottle-fed rather than exclusively breastfed. The need to integrate members of the social network of the woman during pre-natal care, birth and the after birth period should be encouraged, in such a way that social support can serve the mother´s requirements, contributing to exclusive breastfeeding.

Padrões de aleitamento materno exclusivo e internação por diarréia entre 1999 e 2008 em capitais brasileiras / Exclusive breastfeeding and diarrhea hospitalization patterns between 1999 and 2008 in Brazilian State Capitals

A prevalência do aleitamento materno tem aumentado nas duas últimas décadas como resultado das políticas públicas de incentivo a esta prática. Trata-se de estudo epidemiológico ecológico, com base em dados secundários das Capitais Brasileiras e Distrito Federal. As prevalências de aleitamento materno, a população de nascidos vivos e os casos de internação hospitalar por diarreias foram comparados entre os anos de 1999 e 2008. Foi utilizado o teste não-paramétrico de Spearman para correlacionar as variáveis. Foram estudados 1.329.618 nascidos vivos no período. O aumento da prevalência de aleitamento materno exclusivo em crianças com menos de 4 meses de vida teve correlação negativa com as taxas de internação por diarreias (r = -0,483, p = 0,014), sendo essa correlação mais forte para meninas (r = -0,521, p = 0,016) que para os meninos (r = -0,476, p = 0,008). O aumento da prevalência de aleitamento materno exclusivo entre 1999 e 2008 parece estar correlacionado com a diminuição das taxas de internação hospitalar por diarreias no mesmo período, corroborando a importância das políticas públicas de promoção, proteção e apoio do aleitamento materno.

The prevalence of breastfeeding has increased over the past two decades in Brazil, as a result of public breastfeeding policies. The scope of this paper is to analyze the correlation between the increase in the prevalence of breastfeeding and hospitalization rates due to diarrhea. It is an epidemiological ecological study, based on secondary data from Brazilian Capital Cities and the Federal District. The prevalence of breastfeeding, the number of live births, and cases of hospitalization due to diarrhea were compared for the years 1999 and 2008 and the Spearman non-parametric test was used to correlate the variables. During the period, 1,329,618 children under one year of age in 1999 and 2008 were studied. The increase in the prevalence of exclusive breastfeeding among children under 4 months old had a negative correlation with hospitalization rates due to diarrhea (Rho=-0.483, p=0.014). This correlation was stronger for girls (Rho=-0.521, p=0.008) than for boys (Rho=-0.476, p=0.016). The increase in the prevalence of breastfeeding between 1999 and 2008 appears to be correlated to a reduction in hospitalization rates due to diarrhea over the same period, corroborating the importance of public policies to protect, support and promote breastfeeding.
