Breastfeeding duration and nutritional status of infants and toddlers in Spain. LAyDI study (PAPenRed).

INTRODUCTION: Breastfeeding appears to protect the onset of obesity in infants. The aim is to know whether breastfeeding duration is associated with the risk of obesity in infants and toddlers aged 12 and 24 months. MATERIAL AND METHODS: Prospective longitudinal study in a cohort of children born in Spain between April 2017 and March 2018 (LAyDI study) in the paediatric primary care system conducted in the framework of the PAPenRed research network. Analysis of breastfeeding duration (group 1: fewer than 6 months; group: more than 6 months) and its association with anthropometric variables. RESULTS: A total of 1495 patients attended the 12 months preventive child health visit and 1073 patients the 24 months visit. We found a statistically significant association between breastfeeding duration and weight-for-age, BMI-for-age and weight-for-length/height at 12 and 24 months; breastfeeding duration of less than 6 months was significantly associated with overweight and obesity (based on BMI-for-age and weight-for-length/height) at ages 12 and 24 months. Maternal pre-pregnancy BMI acted as a modifier on the association between breastfeeding duration and overweight and obesity (based on BMI-for-age). CONCLUSIONS: A breastfeeding duration of less than 6 months is associated with a higher percentage of overweight and obesity at ages 12 and 24 months, although maternal pre-pregnancy BMI modifies this relationship at 24 months.

Getting breastfeeding started under pandemic visiting restrictions: lessons learned in Germany.

BACKGROUND: The COVID-19 pandemic contact restrictions considerably changed maternal visiting contacts during the time in which breastfeeding is initiated. We wanted to know how maternity ward staff and mothers rated the conditions of starting breastfeeding under contact restrictions. METHODS: In the Breastfeeding in North Rhine-Westphalia (SINA) study, Germany, 2021/22, chief physicians as well as ward staff from 41 (out of 131) maternity hospitals (82 members of the healthcare sector in total) were surveyed by telephone concerning structural and practical conditions for breastfeeding support before and during the pandemic; 192 (out of 426 eligible) mothers answered an online-questionnaire about their breastfeeding experiences at 2 weeks and 2 months after birth. RESULTS: In almost all of the hospitals, visits were restricted due to the pandemic, with the exception of the primary support person. After more than one year of pandemic experience, the ward staff were convinced that the restrictions were mostly positive for the mothers (97.6%) and for the ward staff themselves (78.0%). A total of 80.5% of the ward staff would maintain the restrictions beyond the pandemic. The mothers themselves mostly rated the restrictions in the hospital as being just right; moreover, many mothers voluntarily maintained the restrictions at home, at least in part. CONCLUSIONS: The unprecedented visiting restrictions in hospitals during the pandemic were like an "experiment" born out of necessity. Restricting visiting arrangements may be an underestimated beneficial component for the development of the mother-infant dyad in perinatal breastfeeding care, particularly in healthcare systems where almost all births occur in the maternity hospital.

Current Evidence on Nutrient Intakes and Infant Growth: A Narrative Review of Baby-Led Weaning vs. Conventional Weaning.

Throughout infancy, changes in growth and development are observed, including changes in nutritional requirements; at approximately 6 months of age, when complementary feeding begins, breastmilk and/or formula are no longer the sole source of energy and nutrients. Little is known about the impact of complementary feeding (CF) approaches used during this time on infant nutrition and growth. Baby-led weaning (BLW) has continued to gain popularity over the last two decades, emphasizing the importance of examining the adequacy of different CF methods. This narrative review of 19 studies from January 2010 to April 2024 aims to discuss the differences between BLW and conventional weaning (CW). The definition of BLW varied across studies, and no standard definition has been established. Though no differences in energy were reported, macronutrient and micronutrient intakes were variable between approaches, including for micronutrients such as iron and zinc. Of the few studies with growth data, results comparing BLW and CW were conflicting. Differences were seen in the demographics of parents who chose to follow BLW and breastfeeding prevalence and duration prior to complementary feeding. Additional research is needed to understand the impacts of BLW and CW on nutrient intakes and growth to inform recommendations for infant complementary feeding approaches.

Maternal Breast Growth and Body Mass Index Are Associated with Low Milk Production in Women.

BACKGROUND: Maternal breast volume is determined by the quantity of glandular and adipose tissue, and it undergoes significant changes during pregnancy. These changes are intricately linked to the development of glandular tissue, which most likely reflects lactation capacity. Evidence indicates that women with overweight or obesity exhibit larger breast volume compared to those with a normal body mass index (BMI), emphasizing the close relationship between breast volume and maternal adiposity. Hence, we aim to investigate breast volume growth and maternal BMI as potential risk factors for low milk production. METHODS: Lactating women (n = 609) from the Perth metropolitan area in Western Australia between 2011 and 2023 were included in the analysis. Twenty-four-hour milk production measurements were conducted using the test weighing method, and milk removal frequencies were recorded. Mothers completed questionnaires regarding demographic, obstetric and infant details. Linear and logistic regression models were used to determine maternal and infant factors associated with milk production. RESULTS: Here we show that increasing maternal age and BMI are associated with low milk production. Moreover, larger pre-pregnancy breast volume and breast growth are associated with both higher BMI and milk production. CONCLUSIONS: Women who are older, have an obese BMI and who have minimal pre-pregnancy breast volume and breast growth should be provided with antenatal screening and breastfeeding support as they are more likely to experience low milk production.

Subcutaneous Semaglutide during Breastfeeding: Infant Safety Regarding Drug Transfer into Human Milk.

Postpartum mothers and their healthcare providers often face the challenge of limited data regarding the safety of drug therapies during lactation. Pregnancy can lead to sustained weight gain, and obesity can negatively impact both physical and psychological well-being. The introduction of GLP-1 agonists to augment weight loss has become a topic of interest for many postpartum mothers. Our study aims to investigate the transmission of semaglutide into human milk in the first steps to ensure the safety and health of both lactating mothers and their breastfed infants. Semaglutide quantification was performed using high-resolution liquid chromatography-mass spectrometry. InfantRisk Center Human Milk biorepository released milk samples from eight women collected at 0, 12 and 24 h post-semaglutide administration. Semaglutide was extracted using protein precipitation in methanol, followed by chromatographic separation. Linear calibration curves for the method ranged between 2.5-30 ng/mL, with a limit of detection of 1.7 ng/mL and a limit of quantification of 5.7 ng/mL (LLOQ). Semaglutide was not detected in any of the collected human milk samples. A worst-case scenario of the relative infant dose (RID) was calculated using the LLOQ as the drug concentration in milk when considering semaglutide's bioavailability and long-acting dose profile. The maximum RID projected was 1.26%, far below the standard 10% safety threshold. While questions about long-term infant outcomes, the safety of maternal nutrient intake, and the nutrient content of breast milk remain, our findings suggest that semaglutide concentrations in human milk are unlikely to pose clinical concerns for breastfed infants. These results support healthcare providers in making informed decisions regarding postpartum therapeutic interventions.

Modifiable and Non-Modifiable Factors That Affect Human Milk Oligosaccharides Composition.

Human milk, the gold standard in infant nutrition, is a unique fluid that provides essential nutrients such as lactose, lipids, proteins, and free oligosaccharides. While its primary role is nutritional, it also protects against pathogens. This protection mainly comes from immunoglobulins, with human milk oligosaccharides (HMOs) providing additional support by inhibiting pathogen binding to host cell ligands. The prebiotic and immune-modulatory activity of HMOs strongly depends on their structure. Over 200 individual structures have been identified so far, with the composition varying significantly among women. The structure and composition of HMOs are influenced by factors such as the Lewis blood group, secretor status, and the duration of nursing. HMO profiles are heavily influenced by maternal phenotypes, which are defined based on the expression of two specific fucosyltransferases. However, recent data have shown that HMO content can be modified by various factors, both changeable and unchangeable, including diet, maternal age, gestational age, mode of delivery, breastfeeding frequency, and race. The first part of this overview presents the historical background of these sugars and the efforts by scientists to extract them using the latest chromatography methods. The second part is divided into subchapters that examine modifiable and non-modifiable factors, reviewing the most recent articles on HMO composition variations due to specific reasons and summarizing potential future challenges in conducting these types of studies.

Investigation of Human Milk as a Biological System in a Multicenter Mother-Infant Cohort: Protocol Design and Cohort Profile of the Phoenix Study.

Breastfeeding and human milk are the gold standard for infant feeding. Studying human milk with a systems biology approach in a large longitudinal cohort is needed to understand its complexity and health implications. The Phoenix study is a multicenter cohort study focusing on the interactions of maternal characteristics, human milk composition, infant feeding practices, and health outcomes of Chinese mothers and infants. A total of 779 mother-infant dyads were recruited from November 2021 to September 2022, and 769 mother-infant dyads were enrolled in the study. Scheduled home visits took place at 1, 4, 6, and 12 months postpartum, and 696 dyads (90.5% participants) completed the 12-month visit. At each visit, maternal and infant anthropometry was assessed. Questionnaires were administered to collect longitudinal information on maternal characteristics and lifestyle, infant feeding, and health. Digital diaries were used to record maternal dietary intake, infant feeding, and stool character. Human milk, maternal feces, infant feces, and infant saliva were collected. An external pharmaceutical-level quality assurance approach was implied to ensure the trial quality. Multi-omics techniques (including glycomics, lipidomics, proteomics, and microbiomics) and machine learning algorithms were integrated into the sample and data analysis. The protocol design of the Phoenix study provides a framework for prospective cohort studies of mother-infant dyads and will provide insights into the complex dynamics of human milk and its interplay with maternal and infant health outcomes in the Chinese population.

Effect of Lactational Low-Protein Diet on Skeletal Muscle during Adulthood and Ageing in Male and Female Mouse Offspring.

Sarcopenia is characterised by the loss of skeletal muscle mass and function, which leads to a high risk of increased morbidity and mortality. Maternal malnutrition has been linked to impaired development of skeletal muscle of the offspring; however, there are limited studies that report the long-term effect of a maternal low-protein diet during lactation on the ageing of skeletal muscles. This study aimed to examine how a maternal low-protein diet (LPD) during lactation affects skeletal muscle ageing in the offspring. Pups born from control mothers were lactated by mothers fed with an LPD. Post-weaning, mice were either maintained on an LPD or switched to a control, normal-protein diet (NPD). In males, an LPD mainly affected the size of the myofibres without a major effect on fibre number and led to reduced grip strength in ageing mice (24 months). Female mice from mothers on an LPD had a lower body and muscle weight at weaning but caught up with control mice at 3 months. During ageing, the muscle weight, myofibre number and survival rate of female pups were significantly affected. These findings highlight the effect of an LPD during lactation on skeletal muscle ageing, the lifespan of offspring and the importance of sexual dimorphism in response to dietary challenges.

Multi-Omics Profiles of Small Intestine Organoids in Reaction to Breast Milk and Different Infant Formula Preparations.

Ensuring optimal infant nutrition is crucial for the health and development of children. Many infants aged 0-6 months are fed with infant formula rather than breast milk. Research on cancer cell lines and animal models is limited to examining the nutrition effects of formula and breast milk, as it does not comprehensively consider absorption, metabolism, and the health and social determinants of the infant and its physiology. Our study utilized small intestine organoids induced from human embryo stem cell (ESC) to compare the nutritional effects of breast milk from five donors during their postpartum lactation period of 1-6 months and three types of Stage 1 infant formulae from regular retail stores. Using transcriptomics and untargeted metabolomics approaches, we focused on the differences such as cell growth and development, cell junctions, and extracellular matrix. We also analyzed the roles of pathways including AMPK, Hippo, and Wnt, and identified key genes such as ALPI, SMAD3, TJP1, and WWTR1 for small intestine development. Through observational and in-vitro analysis, our study demonstrates ESC-derived organoids might be a promising model for exploring nutritional effects and underlying mechanisms.

Effectiveness of moisturising therapy in treating nipple trauma: a systematic review protocol.

INTRODUCTION: Breastfeeding is crucial in infant nutrition and bonding, recommended for at least 6 months and up to 2 years postpartum, providing health benefits for both infants and mothers. However, nipple trauma is common among lactating mothers. Moisturising therapies, such as hydrogel application, aim to promote the healing of nipple wounds. Despite various interventions proposed, comprehensive reviews evaluating the efficacy of moisturising therapies for nipple trauma are lacking. This review aims to appraise the effectiveness of moisturising therapy, particularly tailored for nipple trauma in lactating women. METHODS AND ANALYSIS: This systematic review protocol adheres to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines and is registered in the International Prospective Register of Systematic Reviews. The focus will be on both randomised and non-randomised controlled trials addressing the treatment of nipple trauma in lactating women. In this context, 'moisturising therapy' is categorised as a non-pharmacological intervention applied directly to the nipple, excluding treatments for bacterial or fungal infections. The primary outcomes will include measures of the healing efficiency of nipple trauma and reduction in nipple pain. Searches will be conducted without date restrictions across multiple databases, including PubMed, CINAHL, the Cochrane Library, Web of Science, CiNii Research and Ichushi-Web, in addition to exploration of grey literature. Two independent reviewers will manage all stages of the review process, under the supervision of a third reviewer. Data extraction will encompass participant demographics, study methodologies, sample specifics and measured outcomes. Quality assessment will be conducted using the Joanna Briggs Institute Appraisal Checklist Tools. ETHICS AND DISSEMINATION: Ethics approval is not required for this study. The findings of this review will be disseminated through academic publications, detailed reports and presentations at relevant conferences. PROSPERO REGISTRATION NUMBER: CRD42023481761.

Newborn community health advancements among Ethiopian Orthodox Christian women in North Gondar, Ethiopia: community-based randomised trial protocol.

INTRODUCTION: Despite significant progress over past decades, neonatal and infant morbidity and mortality remain unacceptably high in Ethiopia. Simple interventions have been shown to improve the health of children and reduce mortality. These include promotion of exclusive breast feeding for the first 6 months of life, immunisation and utilisation of available newborn healthcare services, which are proven to improve newborn survival. This study aims to determine the impact of a behaviour change intervention that partners Orthodox priests with volunteer community health workers, known in Ethiopia as the Health Development Army and trains them to conduct newborn health outreach to improve care seeking, uptake of key interventions and identification of sick infants. METHODS: The study designed is a community-randomised trial conducted in the Central Gondar area. The behaviour change intervention pairs trained Orthodox priests with members of the Health Development Army to conduct community health outreach by identifying near-term pregnant women in their communities and educating them on the topics of exclusive breast feeding, immunisation, nutrition and uptake of available child healthcare services. The evaluation of the intervention will enrol up to 150 newborn-mother pairs from communities receiving the behaviour change intervention and another 150 pairs enrolled from control communities. The quantitative analysis will be done by comparing data between the intervention and control groups related to breast feeding, anthropometry, immunisation status and uptake of child health services. The primary outcomes are exclusive breastfeeding through 6 months, mid-upper arm circumference, completion of vaccinations and infant hospitalisation. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the University of Washington (STUDY00006942) and the University of Gondar (No.V/P/RCS/05/2523/2019) Institutional Review Boards. Oral consent was obtained for the formative study, whereas written consent (or witnessed thumbprint) will be obtained from all enrolled mothers. Results will be communicated to community members, relevant government agencies and other stakeholders. TRIAL REGISTRATION NUMBER: NCT05111899.

Faecal microbiota and cytokine profiles of rural Cambodian infants linked to diet and diarrhoeal episodes.

The gut microbiota of infants in low- to middle-income countries is underrepresented in microbiome research. This study explored the faecal microbiota composition and faecal cytokine profiles in a cohort of infants in a rural province of Cambodia and investigated the impact of sample storage conditions and infant environment on microbiota composition. Faecal samples collected at three time points from 32 infants were analysed for microbiota composition using 16S rRNA amplicon sequencing and concentrations of faecal cytokines. Faecal bacterial isolates were subjected to whole genome sequencing and genomic analysis. We compared the effects of two sample collection methods due to the challenges of faecal sample collection in a rural location. Storage of faecal samples in a DNA preservation solution preserved Bacteroides abundance. Microbiota analysis of preserved samples showed that Bifidobacterium was the most abundant genus with Bifidobacterium longum the most abundant species, with higher abundance in breast-fed infants. Most infants had detectable pathogenic taxa, with Shigella and Klebsiella more abundant in infants with recent diarrhoeal illness. Neither antibiotics nor infant growth were associated with gut microbiota composition. Genomic analysis of isolates showed gene clusters encoding the ability to digest human milk oligosaccharides in B. longum and B. breve isolates. Antibiotic-resistant genes were present in both potentially pathogenic species and in Bifidobacterium. Faecal concentrations of Interlukin-1alpha and vascular endothelial growth factor were higher in breast-fed infants. This study provides insights into an underrepresented population of rural Cambodian infants, showing pathogen exposure and breastfeeding impact gut microbiota composition and faecal immune profiles.

Timing of Food Introduction and Allergy Prevention: An Update.

Recommendations about allergy prevention through diet are rapidly changing. In just the past several years, multiple organizations have provided updated guidance and recommendations about infant feeding based on recent studies and meta-analyses. In addition to the increased number of studies supporting the benefit of early introduction of allergenic foods, in particular peanut and egg, recent studies demonstrate that infant and maternal diet diversity may also reduce risk of food allergy and atopy. Skin emollients have not been found to be helpful in prevention of food allergy, and more evidence is needed to determine if emollients play a role in prevention of atopic dermatitis.

Determinants of exclusive breastfeeding among infants under six months in Nepal: multilevel analysis of nationally representative household survey data.

BACKGROUND: The benefits of exclusive breastfeeding (EBF) have been universally documented, with evidence of positive impacts on a child's optimal growth, development, and survival. However, EBF practices in Nepal have fluctuated and declined over the last 25 years. In addition to the individual factors of mothers and infants, EBF practices are affected by multiple community-level factors. Understanding these factors is essential for designing breastfeeding promotion programs to improve child nutritional status in Nepal. This study investigated the individual- and community-level determinants of EBF practices among young infants aged 0-5 months in Nepal. METHOD: We used the dataset from the Nepal Demographic and Health Survey 2022. Information on EBF in the past 24 h was available for 540 infants aged 0-5 months. A multilevel mixed-effect logistic regression was used to identify individual- and community-level factors associated with EBF among infants aged 0-5 months in Nepal. RESULTS: The 24-hour prevalence of EBF among infants aged 0-5 months was 57.46% (95% confidence interval (CI): 52.18, 62.57). The infant's age was inversely associated with EBF prevalence at the individual level. Compared with infants aged < 1 month, infants aged three months (adjusted odds ratio (AOR): 0.14, 95% CI: 0.05, 0.40), four months (AOR: 0.11, 95% CI: 0.04, 0.28), and five months (AOR: 0.07, 95% CI: 0.03, 0.20) were less likely to receive EBF. At the community level, community-level variables such as ≥ 4 ANC visits coverage, maternal employment status, and poverty level were generated by aggregating the individual characteristics in a cluster and were categorized using quartiles into low ("< 25%"), moderate (25-75%), and high (≥ 75%). Mothers from communities with moderate ≥ 4 ANC visits (AOR: 3.30, 95% CI: 1.65, 6.57) and high ≥ 4 ANC visits (AOR: 2.70, 95% CI: 1.40, 5.22) coverage had higher odds of EBF practices than did those from communities with low ≥ 4 ANC visits coverage. Similarly, communities with moderate (AOR: 2.67, 95% CI: 1.34, 5.30) and high (AOR: 2.34, 95% CI: 1.10, 4.99) levels of maternal employment status and moderate levels of poverty (AOR: 2.20, 95% CI: 1.13, 4.28) were associated with a higher likelihood of EBF practices. Subnational level variation was evident, with infants in Lumbini province having lower odds of EBF (AOR: 0.32, 95% CI: 0.13, 0.77) relative to Koshi province. Approximately 9% of the variation in EBF practices was observed among mothers while mapping across clusters in this study. CONCLUSION: Various individual- and community-level factors influence the uptake of EBF in Nepal, underscoring the need to improve the approaches and strategies of EBF programs. This study highlighted the significant association of community-level factors (≥ 4 ANC visits coverage, poverty level, and maternal employment status) with EBF among infants under 6 months. It revealed approximately 9% variability in EBF across clusters. Future efforts to promote EBF should focus on older infants and communities with low poverty levels and low coverage of recommended ≥ 4 ANC visits. Furthermore, context-specific adaptation of such efforts might be required considering the variation observed between the communities in the present study.

Development of a breastfeeding co-parenting intervention program for couples with primiparas: a program development process study.

BACKGROUND: The exclusive breastfeeding rates is low in some countries. Low breastfeeding rates results in higher healthcare expenses and adverse health outcomes for individuals and society. Co-parenting is effective in promoting breastfeeding as it involves shared responsibility and collaboration between parents in raising children. However, the current breastfeeding co-parenting intervention programs exhibits significant variations in components, timing, and duration across studies. An evidence-based breastfeeding co-parenting intervention program is essential for enhancing breastfeeding-related outcomes. OBJECTIVE: To develop an evidence-based breastfeeding co-parenting intervention program for healthcare providers to guide parents with primiparas on breastfeeding. METHOD: To form an initial version of the intervention program, a systematic literature review was conducted to consolidate information on current intervention programs. Two rounds of Delphi method were followed to gather expert comments for the program modification to establish the formal version. RESULTS: Fourteen articles published between 1995 and 2022 were screened. Details of these researches, including starting and ending time, duration and specific contents, were integrated to developed the initial program. Then, six experts completed the two rounds consultation with a positive coefficient of 85.71%, coefficient judgment basis of 0.93, familiarity coefficient of 0.87, authority coefficient of 0.90 and the Kendall's W of 0.62. Finally, an evidence-based breastfeeding co-parenting intervention program was constructed in this study, consisting of breastfeeding co-parenting courses, individual counselling and a father's support group. CONCLUSION: This research developed a breastfeeding co-parenting intervention program for healthcare providers to guide primiparous parents to improve breastfeeding rates. Through a systematic literature review and Delphi method with good reliability, the program integrates breastfeeding courses, individual counseling, and a father's support group. Future research will focus on evaluating its impact and scalability to benefit maternal and infant health globally. TRIAL REGISTRATION: ChiCTR.org.cn (ChiCTR2300069648).

Got bile? Breastmilk bile acids influence norovirus infection.

Breastfeeding provides infection protection for several pathogens but not for noroviruses. Mechanisms explaining this discrepancy have been unclear. In this issue of Cell Host & Microbe, Peiper et al. demonstrate that while breastmilk protects mice from intestinal damage, it promotes neonatal murine norovirus infection due to maternal-derived bile acids.1.

[Introduction of complementary feeding and associated factors in preterm and low birthweight newborns: a prospective cohort study]. / Introdução da alimentação complementar e fatores associados em recém-nascidos pré-termo e com baixo peso: estudo de coorte prospectivo.

This study aimed to analyze the association between sociodemographic factors, maternal and neonatal characteristics and the time taken to introduce complementary feeding in low birthweight and preterm newborns. This is a prospective cohort study of 79 preterm newborns weighing less than or equal to 1,800g. Data were collected at the time of hospital discharge and at the 6th, 9th ,and 12th months of corrected gestational age (CGA), using a structured questionnaire to analyze the time taken to introduce complementary feeding and the texture of the foods introduced. Furthermore, the Survey of Well-being of Young Children (SWYC-BR) was used to assess the risk of developmental delay. Cox proportional hazards regression was used to analyze the variables. The introduction of complementary feeding was assessed in preterm newborns based on the median age of introduction of liquid foods (3.50; IQR: 2.50-5.00), followed by solid (4.70; IQR: 3.20-5.20) and soft foods (5.00; IQR: 4.50-5.50). There was also an association with gestational age (RR = 1.25; 95%CI: 1.02-1.52) throughout the process of food introduction. For solid and soft foods, those with the longest length of stay (RR = 1.03; 95%CI: 1.10-1.05) and on mixed breastfeeding (RR = 2.97; 95%CI: 1.24-7.09) delayed the introduction of complementary feeding the longest. For liquid foods, less severe preterm newborns (Score for Neonatal Acute Physiology and Perinatal Extension - SNAPPE II [RR = 0.96; 95%CI: 0.94-0.98]) and mothers who were breastfeeding at hospital discharge (RR = 11.49; 95%CI: 1.57-84.10) delayed the introduction of complementary feeding. Guidelines are needed to better advise professionals and parents and/or guardians on the ideal time to introduce feeding.

O objetivo deste artigo foi analisar a associação entre os fatores sociodemográficos, as características maternas e neonatais e o tempo de introdução da alimentação complementar em recém-nascidos pré-termo e com baixo peso. Trata-se de um estudo de coorte prospectivo feito com 79 recém-nascidos pré-termo com peso menor ou igual a 1.800g. Os dados foram coletados no momento da alta hospitalar e ao 6º, 9º e 12º mês de idade gestacional corrigida (IGC), com auxílio de um questionário estruturado para analisar o tempo de introdução da alimentação complementar e texturas dos alimentos introduzidos. Além disso, para avaliar o risco de atraso de desenvolvimento, utilizou-se o Survey of Well-being of Young Children (SWYC-BR). Para análise das variáveis, aplicou-se regressão de riscos proporcionais de Cox. A introdução da alimentação complementar foi observada nos recém-nascidos pré-termo, com a mediana de idade de introdução de alimentos líquidos (3,50; IQ: 2,50-5,00), seguido por sólidos (4,70; IQ: 3,20-5,20) e pastosos (5,00; IQ: 4,50-5.50). Ainda, verificou-se associação da idade gestacional (RR = 1.25; IC95%: 1,02-1,52) em todo o processo da introdução alimentar. Para os alimentos sólidos e pastosos, aqueles com o maior tempo de internação (RR = 1,03; IC95%: 1,10- 1,05) e em amamentação mista (RR = 2,97; IC95%: 1,24-7,09) adiaram mais o tempo para introduzir a alimentação complementar. Para alimentos líquidos, recém-nascidos pré-termo menos graves (Score for Neonatal Acute Physiology and Perinatal Extension - SNAPPE II [RR = 0,96; IC95%: 0,94-0,98]) e mães que estavam amamentando na alta hospitalar (RR = 11,49; IC95%: 1,57-84,10) postergaram a introdução alimentar. Diretrizes para melhor orientação de profissionais e pais e/ou responsáveis sobre o momento ideal de introdução alimentar se faz necessário.

En el caso de alimentos sólidos y pastosos, aquellos con mayor tiempo de hospitalización (RR = 1,03; IC95%: 1,10-1,05) y en lactancia mixta (RR = 2,97; IC95%: 1,24-7,09) retrasaron más la introducción de alimentación complementaria. En el caso de alimentos líquidos, los recém-nascidos pré-termo menos graves (Score for Neonatal Acute Physiology and Perinatal Extension - SNAPPE II [RR = 0,96; IC95%: 0,94-0,98]) y las madres que estaban amamantando al alta hospitalaria (RR = 11,49; IC95%: 1,57-84,10) pospusieron la introducción de alimentos. Se hacen necesarias pautas para una mejor orientación a profesionales y padres o tutores sobre el momento ideal para la introducción alimentaria.

The effect of breastfeeding on reducing pain induced by pentavalent vaccine in infants: a randomized clinical trial.

OBJECTIVE: To analyze the effect of breastfeeding on reducing Pentavalent vaccination pain in infants and to identify the necessary breastfeeding interval for antinociceptive action. METHOD: Open parallel randomized clinical trial. Ninety mother-infant dyads participated, distributed into intervention group 1 (n = 30), which breastfed five minutes before vaccination; intervention group 2 (n = 30), which breastfed five minutes before and during vaccination; and control group (n = 30), which did not breastfeed. The outcome variable was the pain level measured by the FLACC Scale. Data analysis was conducted using descriptive and inferential statistics, applying Fisher's Exact, Kolmogorov-Smirnov, Kruskal-Wallis and Dunn's multiple comparison tests, with 0.05 significance level. RESULTS: Pain induced by the Pentavalent vaccine was reduced in intervention groups 1 and 2 (mean pain of 6.06 versus 3.83, respectively) compared to the control group (mean of pain of 7.43), which was significant for intervention group 2 (p < 0.001), indicating that, to achieve lower levels of pain, breastfeeding should be carried out before and during vaccination. CONCLUSION: Longer breastfeeding, conducted five minutes before and during vaccination, reduces the pain induced by the Pentavalent vaccine. No vaccination risks were identified to outweigh the benefits. These results endorse that health professionals should encourage breastfeeding at least five minutes before and during vaccine injection for an antinociception effect.
