RESUMO

BACKGROUND: Preterm infants have imperfect neurological development, uncoordinated sucking-swallowing-breathing, which makes it difficult to realize effective oral feeding after birth. How to help preterm infants achieve complete oral feeding as soon as possible has become an important issue in the management of preterm infants. Non-nutritive sucking (NNS), as a useful oral stimulation, can improve the effect of oral feeding in preterm infants. This review aimed to explore the effect of NNS on oral feeding progression through a meta-analysis. METHODS: We systematically searched PubMed, CINHAL, Web of Science, Embase, Cochrane databases, China's National Knowledge Infrastructure (CNKI), Wanfang and VIP database from inception to January 20, 2024. Search terms included 'non-nutritive sucking' 'oral feeding' and 'premature.' Eligibility criteria involved randomized controlled studies in English or Chinese. Studies were excluded if they were reviews, case reports, or observational studies from which valid data could not be extracted or outcome indicators were poorly defined. The meta-analysis will utilize Review Manager 5.3 software, employing either random-effects or fixed-effects models based on observed heterogeneity. We calculated the mean difference (MD) and 95% confidence interval (CI) for continuous data, and estimated pooled odds ratios (ORs) for dichotomous data. Sensitivity and publication bias analyses were conducted to ensure robust and reliable findings. We evaluated the methodological quality of randomized controlled trials (RCTs) utilizing the assessment tool provided by the Cochrane Collaboration. RESULTS: A total of 23 randomized controlled trials with 1461 preterm infants were included. The results of the meta-analysis showed that NNS significantly shortened time taken to achieve exclusive oral feeding (MD = -5.37,95%CI = -7.48 to-3.26, p<0.001), length of hospital stay(MD = -4.92, 95% CI = -6.76 to -3.09, p<0.001), time to start oral feeding(MD = -1.41, 95% CI = -2.36 to -0.45, p = 0.004), time to return to birth weight(MD = -1.72, 95% CI = -2.54 to -0.91, p<0.001). Compared to the NNS group, the control group had significant weight gain in preterm infants, including weight of discharge (MD = -61.10, 95% CI = -94.97 to -27.23, p = 0.0004), weight at full oral feeding (MD = -86.21, 95% CI = -134.37 to -38.05, p = 0.0005). In addition, NNS reduced the incidence of feeding intolerance (OR = 0.22, 95% CI = 0.14 to 0.35, p<0.001) in preterm infants. CONCLUSION: NNS improves oral feeding outcomes in preterm infants and reduces the time to reach full oral feeding and hospitalization length. However, this study was limited by the relatively small sample size of included studies and did not account for potential confounding factors. There was some heterogeneity and bias between studies. More studies are needed in the future to validate the effects on weight gain and growth in preterm infants. Nevertheless, our meta-analysis provides valuable insights, updating existing evidence on NNS for improving oral feeding in preterm infants and promoting evidence-based feeding practices in this population.

RESUMO

Current practice regarding complementary feeding (CF) is influenced by socio-cultural background. Our group already investigated the Italian approach to CF in the years 2015-2017. Our aim was to update those data by finding out: if the habits have changed nationwide, how the trends changed in each area, and if the differences between regions still exist. We devised and submitted to Italian primary care paediatricians (PCP) a questionnaire consisting of four items regarding the suggestions they gave to families about CF and compared the results to the ones from our previous survey. We collected 595 responses. Traditional weaning was the most recommended method, with a significant reduction compared to the period of 2015-2017 (41% vs. 60%); conversely, the proportion of PCP endorsing baby-led weaning (BLW) or traditional spoon-feeding with adult food tastings has increased, while the endorsement of commercial baby foods dropped. BLW is still more popular in the North and Centre compared to the South (24.9%, 22.3%, and 16.7%, respectively). The age to start CF and the habit of giving written information have not changed over time. Our results highlighted that Italian paediatricians encourage BLW and traditional CF with adult tastings more than in the past, at the expense of traditional spoon-feeding.

RESUMO

INTRODUCTION: Over one-quarter of children in sub-Saharan Africa are stunted; however, commercial supplements only partially meet child nutrient requirements, cannot be sustainably produced, and do not resolve physiological barriers to adequate nutrition (eg, inflammation, microbiome dysbiosis and metabolic dysfunction). Redesigning current infant and young child feeding (IYCF) interventions using locally available foods to improve intake, uptake and utilisation of nutrients could ameliorate underlying pathogenic pathways and improve infant growth during the critical period of complementary feeding, to reduce the global burden of stunting. METHODS AND ANALYSIS: Child Health Agriculture Integrated Nutrition is an open-label, individual household randomised trial comparing the effects of IYCF versus 'IYCF-plus' on nutrient intake during infancy. The IYCF intervention comprises behaviour change modules to promote infant nutrition delivered by community health workers, plus small-quantity lipid-based nutrient supplements from 6 to 12 months of age which previously reduced stunting at 18 months of age by ~20% in rural Zimbabwe. The 'IYCF-plus' intervention provides these components plus powdered NUA-45 biofortified sugar beans, whole egg powder, moringa leaf powder and provitamin A maize. The trial will enrol 192 infants between 5 and 6 months of age in Shurugwi district, Zimbabwe. Research nurses will collect data plus blood, urine and stool samples at baseline (5-6 months of age) and endline (9-11 months of age). The primary outcome is energy intake, measured by multipass 24-hour dietary recall at 9-11 months of age. Secondary outcomes include nutrient intake, anthropometry and haemoglobin concentration. Nested laboratory substudies will evaluate the gut microbiome, environmental enteric dysfunction, metabolic phenotypes and innate immune function. Qualitative substudies will explore the acceptability and feasibility of the IYCF-plus intervention among participants and community stakeholders, and the effects of migration on food production and consumption. ETHICS AND DISSEMINATION: This trial is registered at ClinicalTrials.gov (NCT04874688) and was approved by the Medical Research Council of Zimbabwe (MRCZ/A/2679) with the final version 1.4 approved on 20 August 2021, following additional amendments. Dissemination of trial results will be conducted through the Community Engagement Advisory Board in the study district and through national-level platforms. TRIAL REGISTRATION NUMBER: NCT04874688.

RESUMO

Baby-led weaning (BLW), proposed as a new form of complementary feeding, has emerged as a real trend phenomenon in the media. Infants are seated at the family table from the age of 6 months, facing the foods they grab and bring to their mouth: they decide which foods they want to eat and what amount. The consumption of mashed foods and the use of a spoon are totally discouraged. BLW is increasingly used in nurseries and centers of young children. A bibliographic search carried out between 2000 and 2021 found 423 articles, of which 38 were selected. The clinical studies selected are 11 cross-sectional observational studies and two randomized controlled studies. BLW promotes breastfeeding, the early introduction of morsels, the respect of the child's appetite, the use of unprocessed foods, and the choice of "homemade" and friendliness. These benefits can nonetheless be reached with usual complementary feeding (SCF), according to current recommendations. Other benefits are claimed without scientific evidence such as easier achievement of dietary complementary feeding and an optimal growth with prevention of excess weight gain. BLW has some obvious downsides. The infant may not get enough energy, iron, zinc, vitamins, and other nutrients, or too much protein, saturated fat, salt, or sugar. The risk of choking, which must be distinguished from the physiological gagging reflex, has not been ruled out by scientific studies. Currently, the Nutrition Committee of the French Pediatric Society considers that the data published to date in terms of benefits and risks of BLW do not lend themselves to advice for this practice in preference over SCF carried out according to current recommendations.

RESUMO

Food digestion and absorption in infants are closely related to early growth and long-term health. Human milk and infant formula are the main food sources for 0-6 month-old infants. Due to the immature gastrointestinal tract of newborns, mild digestive problems, such as inefficient digestion and impaired absorption of proteins, lipids and lactose, and gut dysbiosis, are often seen in infancy. The differences in composition between infant formula and human milk make mild digestive problems more likely to occur in formula-fed infants. In recent years, several types of infant formulas have been developed to treat or reduce gastrointestinal digestive problems in infants. This review summarizes the gastrointestinal environment of infants and the digestion of human milk and different infant formulas. We particularly focus on the common digestive problems and appropriate nutritional solutions that may occur in healthy term infants during the first six months of life.

RESUMO

Children's executive functions (EFs) emerge over time and can be shaped by household environments and dietary intake. However, there is a lack of knowledge about how these factors influence EFs in children aged 18-24 months. This study tested a model exploring the relations between parent-reported dietary intake, household chaos, and child EF. The sample consisted of 294 families participating in the STRONG Kids2 birth cohort study of nutrition and child health. Caregivers completed the Food Frequency Questionnaire (FFQ), the Confusion, Hubbub, and Order Scale (CHAOS), and the Behavior Rating Inventory of Executive Function®-Preschool Version (BRIEF-P) to assess model variables. Regression analyses revealed a significant and independent association between assorted snacks and processed foods and two EF subscales. There were also significant associations between household chaos and each EF subscale. There was no significant moderation effect. These findings suggest that family households characterized by dysregulation are associated with children's EF difficulties during early childhood and that the role of unhealthy dietary intake in child EF should be explored further. Future longitudinal studies that include multi-method approaches are needed to document the mechanisms through which household chaos impacts child EF over time.

RESUMO

Malnutrition continues to be a primary concern for researchers and policymakers in India. There is limited scientific research on the effect of agriculture on child nutrition in the country using a large representative sample. To the best of our knowledge, no study has examined the spatial clustering of child malnutrition and its linkage with agricultural production at the district-level in the country. The present study aims to examine agricultural production's role in improving the nutritional status of Indian children through child feeding practices. The nutritional indicators of children from the National Family Health Survey-4 (2015-16) and the agricultural production data for all the 640 districts of India obtained from the District-Wise Crop Production Statistics (2015-16), published by the Ministry of Agriculture, Government of India were used for the analysis. The statistical analysis was undertaken in STATA (version 14.1). ArcMap (version 10.3), and GeoDa (version 1.8) were used for the spatial analysis. The study found a higher prevalence of malnutrition among children who had not received Minimum Meal Frequency (MMF), Minimum Dietary Diversity (MDD), and Minimum Acceptable Diet (MAD). Further, child feeding practices- MMF, MDD, and MAD- were positively associated with high yield rates of spices and cereals. The yield rate of cash crops, on the contrary, harmed child feeding practices. Production of pulses had a significant positive effect on MDD and MAD. Districts with high cereal yield rates ensured that children receive MMF and MAD. There is a significant spatial association between child feeding practices and malnutrition across Indian districts. The study suggests that adopting nutrient-sensitive agriculture may be the best approach to improving children's nutritional status.

RESUMO

Inconsistent conclusions from infant sleep and feeding studies may influence parents feeding-related decisions. This study aimed to systematically review the existing literature on infant sleep and its relation to the timing of introduction to complementary foods and type of milk feeding to better understand their role(s) in infant sleep. Cohort, longitudinal, cross-sectional studies, and controlled trials were identified using online searches of five databases up to April 2020. Twenty-one articles with a total of 6225 infants under 12 months-of-age were eligible. Exclusively breastfed infants (≤6 months-of-age) had a greater number of night wakings, but most studies (67%) reported no difference in night-time and 24 h sleep duration compared to formula-fed infants. However, after 6 months-of-age, most studies (>65%) reported breastfed infants to sleep less in the night-time and over 24 h compared to formula-fed infants. Furthermore, studies reported no association between the timing of introduction to complementary foods and infant sleep duration (<12 months-of-age). Future studies using standardized methodologies and definitions, transdisciplinary expertise, and longitudinal design are required to better understand the complex role of feeding on sleep.

RESUMO

INTRODUCTION: Long-chain polyunsaturated fatty acids (LC-PUFAs) are critical for infant growth and development, particularly arachidonic acid (ARA, C20:4n-6) and docosahexaenoic acid (DHA, C22:6n-3). ARA and DHA are components of cell membrane phospholipids and play an important role in cell division, differentiation, and signaling; and DHA is the n-3 fatty acid predominant in the developing brain and retina. During the third trimester of pregnancy, LC-PUFAs increase substantially in fetal circulation, and a "biomagnification" process in the fetal brain is observed. Moreover, LC-PUFAs are precursors of eicosanoids and metabolites, which modulate the intensity and duration of the immune response. LC-PUFA synthesis implies complex desaturation and elongation processes on their principal precursors, linoleic acid (LA) (18:3 n-6) (series n-6) and α-linolenic acid (LNA) (20:3 n-3) (series n-3), where fatty acid desaturases (FADS) and elongases (ELOVL) are competing. It is important to notice that during the first months of life, as a consequence of low enzymatic activity, LC-PUFA synthesis from LA and LNA is reduced, especially in those infants carrying variations in the FADS and ELOVL genes, which are involved in LC-PUFA synthesis, and so they are unable to supply their own DHA and ARA needs. Homozygote infants for FADS haplotype A (97 % of the Latinoamerican population) show low levels of ARA (only 43 %) and DHA (only 24 %) when compared to those carrying haplotype D (more prevalent in Europe, Africa and Asia). Human milk is the only source of LA, LNA, ARA, and DHA for the neonate and infant till complementary feeding (CF) is introduced. Infants fed with infant formulas must receive enough amounts of LA, LNA, ARA, and DHA to cover their nutritional requirements. The new guidelines by the European Food Safety Authority (EFSA) (2016) recommend that infant formulas and follow-on formulas must contain 20-50 mg of DHA/100 kcal (0.5-1 % of total fatty acids, which is higher than in human milk and the majority of infant formulas in the market), and it is not necessary to add ARA. This new regulation, which is already applicable since February 2020, has resulted in profound controversy because there is no scientific evidence about its appropriateness and safety for healthy children. Then, different international expert groups have revised the research already published about the effects of ARA and DHA addition to infant formulas, and discussed different emerging questions from this European directive. The expert group led from the University of Granada (Spain) recommends the addition of ARA in similar or higher concentrations than those of DHA, at least equal to those present in human milk (0.3 % of total fatty acids), although preferably 0.5 % and up to around 0.64 % of total fatty acids, since new studies confirm the optimal intake of ARA and DHA during the different developmental stages. This recommendation could be of particular importance for infants carrying the haplotype A of FADS.


INTRODUCCIÓN: Los ácidos grasos poliinsaturados de cadena larga (AGPI-CL) son críticos para el crecimiento y desarrollo infantil, en particular los ácidos araquidónico (ARA, C20:4n-6) y docosahexaenoico (DHA, C22:6n-3). El ARA y el DHA son componentes de los fosfolípidos de las membranas celulares y desempeñan importantes funciones en la división, diferenciación y señalización celular, siendo el DHA el ácido graso de la serie n-3 predominante en el cerebro y la retina en desarrollo. Durante el tercer trimestre de la gestación, los AGPI-CL aumentan de forma sustancial en la circulación fetal, observándose un proceso de "biomagnificación" en el cerebro fetal. Además, los AGPI-CL son precursores de los eicosanoides y metabolitos implicados en la modulación de la intensidad y duración de la respuesta inmunitaria. La síntesis de AGPI-CL implica un complejo proceso de desaturación y elongación desde los precursores principales, el ácido linoleico (18:3 n-6) (LA) (serie n-6) y el ácido α-linolénico (20:3 n-3) (LNA) (serie n-3), por los cuales compiten las enzimas desaturasas (FADS) y elongasas (ELOVL). Es importante indicar que en los primeros meses de vida, como consecuencia de la baja actividad enzimática, la síntesis de AGPI-CL a partir de LA y LNA es reducida, especialmente en los niños con variaciones en los genes que codifican las FADS y ELOVL involucradas en la síntesis de AGPI-CL y que, por tanto, son incapaces de cubrir por sí mismos sus necesidades de ARA y DHA. Los homocigotos para el haplotipo A de las FADS (97 % de la población latinoamericana) muestran niveles de ARA y DHA de tan solo un 43 % y un 24 %, respectivamente, inferiores a los de los individuos con haplotipo D (más frecuente en Europa, África y Asia). La leche humana constituye la única fuente de LA, LNA, ARA y DHA para el recién nacido y el lactante hasta la introducción de la alimentación complementaria (AC). Los niños alimentados con fórmulas infantiles deben recibir las cantidades de LA, LNA, ARA y DHA suficientes para cubrir los requerimientos nutricionales. La nueva normativa de la Autoridad Europea de Seguridad Alimentaria (EFSA) (2016) indica que las fórmulas infantiles de inicio y continuación deben contener entre 20 y 50 mg de DHA/100 kcal (0,5-1 % del total de ácidos grasos: más elevado que en la leche humana y en la mayoría de fórmulas infantiles comercializadas) sin la necesidad de incluir también ARA. Esta nueva regulación, que está vigente desde febrero de 2020, ha despertado una gran controversia, al no existir evidencia científica acerca de su pertinencia y seguridad para los niños sanos. Por ello, diferentes grupos de expertos internacionales han revisado la investigación publicada acerca del ARA y el DHA, y discutido diferentes cuestiones emergentes a partir de esta nueva directiva Europea. El grupo de expertos, liderado desde la Universidad de Granada (España), recomienda la adición de ARA en concentraciones iguales o mayores que las de DHA, alcanzando al menos el contenido presente en la leche humana (0,3 % del total de ácidos grasos), aunque preferiblemente un 0,5 % y hasta alrededor del 0,64 % del total de AG, hasta que nuevos estudios confirmen la ingesta óptima de ARA y DHA durante las distintas etapas del desarrollo. Esta recomendación podría ser de especial importancia para los niños portadores del haplotipo A de las FADS.

RESUMO

We cross-culturally adapted and validated the Infant Feeding Style Questionnaire (IFSQ) in Brazil. The cross-cultural adaptation and content validity assessment was conducted in five steps: translation, synthesis of translations, back-translation, evaluation by experts, and pre-test. To evaluate reliability, construct validity, and floor and ceiling effects, interviews were conducted with 465 mother-infant pairs at Primary Health Centers in the Federal District, Brazil. The mothers answered the Brazilian Portuguese version of the IFSQ (IFSQ-Br), which evaluated four feeding styles (laissez-faire, pressuring, restrictive, and responsive) from 9 sub-constructs. The indulgent style was not evaluated due to time limitation. We performed reliability analysis using Cronbach's alpha coefficient and construct validity was evaluated through Confirmatory Factor Analysis. Higher means were found in the sub-constructs of the responsive and restrictive styles. The IFSQ-Br presented adequate reliability (α = 0.73) with values for the Cronbach's alpha coefficient of the sub-constructs ranging from 0.42 to 0.75. In the Confirmatory Factor Analysis, the final models presented good fit, with the Comparative Fit Indices (CFI) ranging from 0.86 to 1.0 and the Root-Mean Squared Error of Approximation (RMSEA) between 0.0 and 0.09. The IFSQ-Br was shown to be a valid and reliable questionnaire to evaluate maternal feeding beliefs and behaviors in Brazil. Future studies should evaluate the psychometric properties of the indulgent style and include mother-infant pairs from different cultural contexts in Brazil.

RESUMO

Does the quality of our diet during early life impact our long-term mental health? Accumulating evidence suggests that nutrition interacts with our genes and that there is a strong association between the quality of diet and mental health throughout life. Environmental influences such as maternal diet during pregnancy or offspring diet have been shown to cause epigenetic changes during critical periods of development, such as chemical modifications of DNA or histones by methylation for the regulation of gene expression. One-carbon metabolism, which consists of the folate and methionine cycles, is influenced by the diet and generates S-Adenosylmethinoine (SAM), the main methyl donor for methylation reactions such as DNA and histone methylation. This review provides current knowledge on how the levels of one-carbon metabolism associated micronutrients such as choline, betaine, folate, methionine and B vitamins that play a role in brain function can impact our well-being and mental health across the lifespan. Micronutrients that act as methyl donors for SAM formation could affect global or gene methylation, altering gene expression and phenotype. Strategies should then be adopted to better understand how these nutrients work and their impact at different stages of development to provide individualized dietary recommendations for better mental health outcomes.

RESUMO

The feeding of colostrum and mother's transitional milk improves immune protection and neurodevelopmental outcomes. It also helps with gut maturation and decreases the risks of infection. The supply of nutrients from human milk (HM) is not adequate for preterm infants, even though preterm mother's milk contains higher concentrations of protein, sodium, zinc, and calcium than mature HM. The human milk fortifiers, particularly those with protein, calcium, and phosphate, should be used to supplement HM to meet the necessities of preterm infants. The management of fluid and electrolytes is a challenging aspect of neonatal care of preterm infants. Trace minerals such as iron, zinc, copper, iodine, manganese, molybdenum, selenium, chromium, and fluoride are considered essential for preterm infants. Vitamins such as A, D, E, and K play an important role in the prevention of morbidities, such as bronchopulmonary dysplasia, retinopathy of prematurity, and intraventricular hemorrhage. Therefore, supplementation of HM with required nutrients is recommended for all preterm infants.

RESUMO

Enteral feeding is the preferred method of nutrient provision for preterm infants. Though parenteral nutrition remains an alternative to provide critical nutrition after preterm delivery, the literature suggests that enteral feeding still confers significant nutritional and non-nutritional benefits. Therefore, the purpose of this narrative review is to summarize health and clinical benefits of early enteral feeding within the first month of life in preterm infants. Likewise, this review also proposes methods to improve enteral delivery in clinical care, including a proposal for decision-making of initiation and advancement of enteral feeding. An extensive literature review assessed enteral studies in preterm infants with subsequent outcomes. The findings support the early initiation and advancement of enteral feeding impact preterm infant health by enhancing micronutrient delivery, promoting intestinal development and maturation, stimulating microbiome development, reducing inflammation, and enhancing brain growth and neurodevelopment. Clinicians must consider these short- and long-term implications when caring for preterm infants.

RESUMO

BACKGROUND: Small and nutritionally at-risk infants under 6 months (<6m) are a vulnerable group at increased risk of mortality, morbidity, poor growth and sub-optimal development. Current national and international (World Health Organization) management guidelines focus mainly on infants' needs, yet growing evidence suggests that maternal factors also influence infant outcomes. We aimed to inform future guidelines by exploring the impacts of maternal-focused interventions on infant feeding and growth. METHODS: We conducted a systematic review of reviews published since 2008 (PROSPERO, register number CRD 42019141724). We explored five databases and a wide variety of maternal-focused interventions based in low- and middle-income countries. Infant outcomes of interest included anthropometric status, birthweight, infant mortality, breastfeeding and complementary feeding practices. Given heterogenous interventions, we present a narrative synthesis of the extracted data. RESULTS: We included a total of 55 systematic reviews. Numerous maternal interventions were effective in improving infant growth or feeding outcomes. These included breastfeeding promotion, education, support and counselling interventions. Maternal mental health, while under-researched, showed potential to positively impact infant growth. There was also some evidence for a positive impact of: women's empowerment, m-health technologies, conditional cash transfers, water, sanitation and hygiene and agricultural interventions. Effectiveness was increased when implemented as part of a multi-sectoral program. Antenatal supplementation with macronutrient, multiple micronutrients, Vitamin D, zinc, iron folic acid and possibly calcium, iodine and B12 in deficient women, improved birth outcomes. In contrast, evidence for postnatal supplementation was limited as was evidence directly focusing on small and nutritionally at-risk infants; most reviews focused on the prevention of growth faltering. CONCLUSION: Our findings suggest sufficient evidence to justify greater inclusion of mothers in more holistic packages of care for small and nutritionally at-risk infants aged <6m. Context specific approaches are likely needed to support mother-infant dyads and ensure infants survive and thrive.

RESUMO

INTRODUCTION: With the aim of improving the care of the premature newborn during their hospital stay, and their well-being in the transition from enteral to independent feeding, it is proposed to incorporate an assessment system within a Spanish Neonatal Unit. The translation of the Early Feeding Skills Assessment (EFSA) tool is presented, along with a study of its measurement properties. PATIENTS AND METHOD: A total of 104 assessments were made on premature babies of less than 34 + 6 weeks of gestational age, admitted to the neonatal unit with total or partial feeding, including a normal neurological examination for their age and with physiological stability. RESULTS: The EFSA 2010 tool achieved an acceptable value (0.76) as regards its internal consistency. The EFSA 2018 tool maintained an acceptable internal consistency value (0.751). As regards the reliability between two observers, the results showed a satisfactory and excellent reliability in 57.69% of the items in the EFSA 2010 tool, a property that improved in the EFSA 2018 tool (73.68%). CONCLUSIONS: The Spanish version of the EFSA tool is consistent and reliable for use as a tool for the assessment of oral abilities for feeding premature babies admitted into a Spanish Neonatal Unit.

RESUMO

The FEEDMI Study (NCT03663556) evaluated the influence of infant feeding (mother's own milk (MOM), donor human milk (DHM) and formula) on the fecal microbiota composition and alkaline phosphatase (ALP) activity in extremely and very preterm infants (≤32 gestational weeks). In this observational study, preterm infants were recruited within the first 24 h after birth. Meconium and fecal samples were collected at four time points (between the 2nd and the 26th postnatal days. Fecal microbiota was analyzed by RT-PCR and by 16S rRNA sequencing. Fecal ALP activity, a proposed specific biomarker of necrotizing enterocolitis (NEC), was evaluated by spectrophotometry at the 26th postnatal day. A total of 389 fecal samples were analyzed from 117 very preterm neonates. Human milk was positively associated with beneficial bacteria, such as Bifidobacterium, Bacteroides ovatus, and Akkermancia muciniphila, as well as bacterial richness. Neonates fed with human milk during the first week of life had increased Bifidobacterium content and fecal ALP activity on the 26th postnatal day. These findings point out the importance of MOM and DHM in the establishment of fecal microbiota on neonates prematurely delivered. Moreover, these results suggest an ALP pathway by which human milk may protect against NEC.

RESUMO

Considering the importance of iodine to support optimal growth and neurological development of the brain and central nervous system, this study aimed to assess and evaluate iodine status in Norwegian infants. We collected data on dietary intake of iodine, iodine knowledge in mothers, and assessed iodine concentration in mother's breast milk and in infant's urine in a cross-sectional study at two public healthcare clinics in the inland area of Norway. In the 130 mother-infant pairs, the estimated infant 24-h median iodine intake was 50 (IQR 31, 78) µg/day. The median infant urinary iodine concentration (UIC) was 146 (IQR 93, 250) µg/L and within the recommended median defined by the World Health Organization for this age group. Weaned infants had a higher UIC [210 (IQR 130, 330) µg/L] than exclusively breastfed infants [130 (IQR 78, 210) µg/L] and partially breastfed infants [135 (IQR 89, 250) µg/L], which suggest that the dietary data obtained in this study did not capture the accurate iodine intake of the included infants. The iodine status of infants in the inland area of Norway seemed adequate. Weaned infants had higher UIC compared to breastfed infants, suggesting early access and consumption of other sources of iodine in addition to breast milk.

RESUMO

INTRODUCTION: Childhood undernutrition is a major public health problem especially in low and middle-income countries (LMIC). The prevalence of early introduction of complementary feeding, low meal frequency, and low dietary diversity are frequent in LMICs. The effect of inappropriate complementary feeding practices on the nutritional status of children is not well documented in East African countries including Tanzania. Therefore, this study aimed at determining the effect of inappropriate complementary feeding practices on the nutritional status of children aged 6-24 months in urban Moshi, Tanzania. METHODOLOGY: A retrospective cohort study was done using the Pasua and Majengo cohorts of mother-child pairs in urban Moshi who were enrolled from 2002 to 2017. About 3355 mother-child pairs were included in the analysis. Appropriate complementary feeding practices were assessed using WHO IYFP indicators such as age at introduction of solid, semi-solid, or soft foods, minimum dietary diversity, and minimum meal frequency. Nutritional status (stunting, wasting, and underweight) was determined. Multilevel modeling was applied to obtain the effect of inappropriate complementary feeding practices on the nutritional status of children and to account for the clustering effect of mothers and children and the correlation of repeated measures within each child. RESULTS: Majority of the children (91.2%) were given soft/semi-solid/solid foods before six months of age, 40.3percent had low meal frequency, and 74percent had low dietary diversity. Early introduction of complementary food at age 0-1 month was statistically significantly associated with higher risks of wasting and underweight (ARR 2.9, 95%CI 1.3-6.3; and ARR 2.6, 95% CI 1.3-5.1 respectively). Children with low minimum meal frequency had higher risks of stunting, wasting, and underweight (ARR 2.9, 95%CI 2.3-3.6; ARR 1.9, 95%CI 1.5-2.5 and ARR 1.9, 95%CI 1.5-2.4 respectively). Children with low minimum dietary diversity were more likely to be stunted than is the case with their peers who received the minimum dietary diversity (ARR 1.3, 95% CI 1.01-1.6). CONCLUSION: There were a high proportion of children, which were fed inappropriately; Inappropriate complementary feeding practices predisposed children to undernutrition. Our study supports the introduction of complementary feeding, providing minimum dietary diversity, and minimum feeding frequency at six months of age as important in improving the nutritional status of the children.

RESUMO

Ensuring the nutritional demands of preterm (PT) infants during complementary feeding could contribute significantly to the infants' long-term health and development. However, the dietary guidelines for complementary feeding in PT are scarce. Thus, describing dietary intake and identifying nutritional targets for these infants could be of great interest. The aim of this study is to assess the food intake and anthropometric parameters in a Mediterranean infant cohort from 6 to 24 months and to identify nutritional targets especially focused on late preterm infants. This is a longitudinal prospective study analyzing information from administered questionnaires about general characteristics and food frequency consumption in 115 infants (20 PT (32 to 36 gestational weeks), 95 full-term (FT)) at 6, 12 and 24 months of age. Results show that the differences in the prevalence of underweight observed in PT infants vs. FT infants are maintained for up to 6 months of age but disappear at 12 and 24 months. The age of inclusion of new foods and the average intake of the main food groups was not different from that of FTs. Although protein intake at 6 months was directly correlated with weight gain and growth in FT, these associations were not observed in PT. At the nutritional level, the low intake of vitamin D in preterm infants is noteworthy. These findings may be useful when designing new intervention strategies for this population group.
