Influences in food selection during complementary feeding in breastfeeding infants: A systematic review and metasynthesis of qualitative studies

In the transition period from breastfeeding to the introduction of complementary feeding, the choice of food is extremely important for the child's development as many factors may be related. This study aims to investigate, through a systematic review and qualitative meta-synthesis, influence in the selection of foods in the introduction of complementary foods for children, including qualitative studies without language or publication period restrictions. Searches were performed in PubMed, LILACS, SciELO, Cinahl, Embase, Web of Science, and Scopus. Initially, 12,489 articles were selected for tittle reading, 13 were included in the review. Four analytical themes related to factors influencing complementary feeding were identified: family socioeconomic conditions, cultural and family aspects, guidance and advice from health professionals, and factors inherent to the infant. Economic factors, such as the opportunity to offer foods not consumed during the parents' childhood, were emphasized. The influence of grandmothers' opinions and community beliefs and traditions were considered. Trust in pediatricians and community health agents' advice, although considered, conflicted with cultural and family traditions. Mothers/caregivers often preferred to offer foods the child shows preference for, rather than introducing new flavors. The findings underscore the need for a better understanding of qualitative aspects.

Complementary feeding challenges: Insights from Swiss parents' perspectives

Parents play a crucial role in deciding what foods to introduce to their infants during the transition from milk to solids. This study examined the challenges they face, including adherence to official complementary feeding recommendations and the struggles and concerns across different stages of feeding. Specifically, this study focused on the initial stage (transition from breastmilk/formula to mashed foods), middle stage (consumption of mashed foods and some fingerfoods, transitioning towards family foods) and late stage (complete transition to family diet). Findings from 22 semi-structured interviews with Swiss parents reveal that, despite being well-informed, practical obstacles such as returning to work, limited time for preparing homemade foods, managing multiple children, and food preferences often hinder adherence. Safety concerns like allergies and choking were prominent early on but decreased as infants grew older and parents gained confidence. In the middle phase, concerns shifted towards pesticides, indicating a growing awareness of food quality. Maintaining a healthy diet was a constant concern, with early reassurance from breastfeeding or formula feeding giving way to worries about balanced nutrition as solids became more prominent. Time constraints were particularly significant in the first two stages, due to the effort of preparing small amounts of mash and later cooking separate meals. Tailored support and clear communication can help parents navigate these challenges and promote healthier feeding practices.

Importance of dietary fiber in children

Dietary fibers (DFs) are essential components of human nutrition and are principally defined as non-digestible carbohydrates (oligosaccharides and polysaccharides) usually classified by their physicochemical and physiological characteristics (water solubility, viscosity, fermentability, and bulking effect). Unfortunately, there is limited information on dietary fiber recommendations for children, and the evidence on their effect on health and symptom control is mainly available for the adult population. Therefore, this review aims to give a comprehensive overview of the characteristics and dietary sources of dietary fiber and their potential health benefits in healthy children but also their potential use in the treatment of sick children.

Length-weight growth analysis up to 12 months of age in three groups according to the dietary pattern followed from pregnant mothers and children during the first year of life

BACKGROUND

The aim of the present study was to analyze the length-weight growth up to 12 months of age in three groups considering the respective dietary pattern followed from the pregnant mothers and from the infants during the first year of the life. Moreover, the cultural inference of vegetarianism has been studied.

METHODS

Between September 2017 and May 2018, more than 100 mothers have been proposed to participate in this study. As a result of preliminary evaluation, which ensures the presence of inclusion criteria and the absence of exclusion criteria, 55 mothers and their 63 children have been enrolled and assessed with a questionnaire previously created for the study.

RESULTS

A statistically significant difference has emerged between the omnivorous and the vegan group from the comparison for the weight of children at birth, 6 months and 12 months, both when expressed in grams and when expressed in growth percentiles. Furthermore, between the two children groups just mentioned, a significant difference has emerged from the comparison for the length expressed in growth percentiles at 12 months and for the Body Mass Index at 6 months. No statistically significant differences have emerged between the omnivorous group and the lacto-ovo/lacto-vegetarian group and between the latter and the vegan one.

CONCLUSIONS

Although differences between the three groups of children have emerged with regard to some anthropometric parameters, their length-weight growth during the first year of life has been harmonic and physiological regardless of the type of planned diet.

Beliefs, Evaluations, and use of commercial infant Food: A survey among German parents

Complementary feeding is a critical milestone for parents, who must decide the extent to which they feed their infants with homemade foods (HMFs) or commercial infant foods (CIFs). The current study focused on how parents perceive and evaluate CIFs and what drives them to use these products. Understanding the wide variety of factors that influence parents' decisions to use CIFs as a food source is crucial to helping them make more balanced food choices for their infants. Data from an online survey with 858 German parents revealed their negative perceptions of CIFs, particularly in terms of nutritional quality and texture, and concerns that CIFs contain higher levels of pesticides and heavy metals compared to HMFs, despite acknowledging the expertise of the infant nutrition industry. These perceptions were likely to be driven by the 'natural-is-better' belief and parents' desire for control over the ingredients in their infants' meals, contributing to their skepticism towards CIFs. Additionally, our study found that while many parents know traditional nutrition guidelines, they are less familiar with recent updates. Parents' benefit beliefs about CIFs and parents' trust in the food industry strongly influenced the use of CIFs, while infant age and parent gender had a less strong, yet significant influence on CIFs consumption. Overall, the present study offers new quantitative insights into the factors that motivate parents to use CIFs. Furthermore, it underscores the need for health authorities to improve their communication strategies towards parents concerning new dietary guidelines.

Practices for introducing complementary foods in Taiwan: A nationwide survey from 2013 to 2016

BACKGROUND/PURPOSE

Introducing complementary foods to infants is a critical stage in their healthy growth and development process. In this study, we analyzed the feeding habits and choices of caregivers in Taiwan during this essential transition period.

METHODS

Data from the 2013-2016 Nutrition and Health Survey in Taiwan were analyzed. Using a multistage stratified sampling technique, we collected data through questionnaires on the feeding practices, challenges, and information sources associated with complementary feeding. We also investigated the timing of introducing various foods. Certain feeding indicators recommended by the World Health Organization were modified and used for analysis.

RESULTS

Among 439 caregivers of infants aged 2-24 months, complementary feeding typically began at 5 months, and it primarily began with cereals and pureed foods. At 6-8 months of age, 98.29% of the infants received these foods. Only 48.39% of infants aged 6-24 months consumed eggs or flesh foods. Among the primary challenges for caregivers were concerns regarding infants' adaptation to new foods (38.2%), refusal of foods by infants (37.1%), and uncertainty regarding which foods to introduce (11.4%). The main sources of information were friends and family (46.9%), the Internet (46.5%), and baby care books (35.6%). Notably, approximately 51% of the respondents used commercial baby foods.

CONCLUSION

In Taiwan, although the majority of infants begin complementary feeding on time, the introduction of eggs and flesh foods is typically delayed. Given the growing reliance on the Internet in the modern age, accurate feeding information should be disseminated online.

Nutritional Considerations of Plant-Based Diets for People With Food Allergy

Plant-based diets (PBD) have been reported throughout history, but are increasingly common in current times, likely in part due to considerable emphasis on climate change and human health and wellness. Many dietary organisations around the world endorse well-planned, nutritionally adequate PBD, which exclude some or all forms of animal-based foods. However, special attention must be given to patients who follow PBD and also have food allergy (FA), as avoidance may increase the risk of developing nutritional deficiencies, including poor growth in children, weight loss in adults and vitamin and mineral deficiencies. Given the increasing prevalence of both PBD and food allergen avoidance diets, healthcare providers are likely to counsel patients with FA who also follow a PBD. In this review, an overview of PBD in patients with FA is provided, including recent trends, macro- and micronutrient needs, and growth for children and weight gain considerations for adults. With regard to a PBD, special attention should be given to ensure adequate fat and protein intake and improving the bioavailability of several minerals such as iron, zinc, iodine, calcium and magnesium, and vitamins such as A, B2, B12 and D. Although the collective data on growth amongst children following a PBD are varied in outcome and may be influenced in part by the type of PBD, growth must be regularly monitored and in adults weight gain assessed as part of any clinical assessment in those people with FA.

Food oral processing and eating behavior from infancy to childhood: evidence on the role of food texture in the development of healthy eating behavior

Eating behaviors develop in early life and refine during childhood, shaping long-term food choice and dietary habits, which underpin optimum growth and health. The development of Food Oral Processing (FOP) is of major importance in the establishment of eating behaviors at two scale levels: for the initial acceptance of food texture and for the longer-term development of eating behaviors associated to food intake. To date, both processes have been studied as independent topics and the current review proposes a parallel vision on their development from the onset of complementary feeding to later childhood. Individual factors affecting these FOP-related behaviors as they relate to food texture acceptance are discussed, alongside examples of interventions aiming at modifying them. Opportunity to better consider food textures when designing foods for children is addressed. Altogether, the review demonstrates the critical role of food texture in the development of a child's FOP skills, eating habits, and dietary patterns. These scientific knowledges need to be considered for the development of healthier eating behavior. We identify research gaps that need to be addressed and highlight the need to design foods that can support the development of healthy oral processing and eating behaviors among infants and children.

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.

Relationship between Infant Feeding and the Microbiome: Implications for Allergies and Food Intolerances

Childhood is a critical period for immune system development, which is greatly influenced by the gut microbiome. Likewise, a number of factors affect the gut microbiome composition and diversity, including breastfeeding, formula feeding, and solid foods introduction. In this regard, several studies have previously demonstrated that breastfeeding promotes a favorable microbiome. In contrast, formula feeding and the early incorporation of certain solid foods may adversely affect microbiome development. Additionally, there is increasing evidence that disruptions in the early microbiome can lead to allergic conditions and food intolerances. Thus, developing strategies to promote optimal infant nutrition requires an understanding of the relationship between infant nutrition and long-term health. The present review aims to examine the relationship between infant feeding practices and the microbiome, as well as its implications on allergies and food intolerances in infants. Moreover, this study synthesizes existing evidence on how different eating habits influence the microbiome. It highlights their implications for the prevention of allergies and food intolerances. In conclusion, introducing allergenic solid foods before six months, alongside breastfeeding, may significantly reduce allergies and food intolerances risks, being also associated with variations in gut microbiome and related complications.

Dietary Strategies in the Prevention and Treatment of Hypertension in Children and Adolescents: A Narrative Review

This study aims to gather information on effective dietary strategies for the prevention and treatment of hypertension (HTN) in children and adolescents. It discusses specific nutritional models such as the Diet Approaches to Stop Hypertension (DASH diet), traditional Asian diets, plant-based diets, the Southern European traditional Atlantic diet, and the Mediterranean diet, highlighting the benefits of these approaches. The manuscript also addresses dehydration resulting from insufficient fluid intake among children, as well as the consumption of inappropriate beverages, like soft drinks and energy drinks, which contributes to the development of HTN. Additionally, it examines the role of oxidative stress in the pathomechanism of HTN in children, particularly in relation to the antioxidant potential of food components such as selenium, magnesium, and selected vitamins. The relationship between sodium and potassium intake from food and the development of HTN in children is also explored. Finally, this study discusses public health strategies for the prevention of HTN in children. A comprehensive search was performed across multiple databases, such as PubMed/MEDLINE, the Cochrane Library, Science Direct, and EBSCO. This search focused on locating English-language meta-analyses, systematic reviews, randomized clinical trials, and observational studies from around the globe.

Early diet and the risk of coeliac disease. An update 2024 position paper by the ESPGHAN special interest group on coeliac disease

This position paper by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Special Interest Group on Coeliac Disease (SIG-CD) presents an update to the 2016 recommendations concerning early diet and the risk of coeliac disease (CD). This update adheres to the policy that mandates reviewing guidelines every 5 years, particularly when new data emerge. The 2024 statements and recommendations are essentially similar to the 2016 recommendations. Breastfeeding, whether any amount, exclusive, or of any duration, does not reduce the risk of developing CD. Introducing gluten into an infant's diet at any time between completed 4 months (≥17 weeks) and 12 months of age does not affect the cumulative incidence of CD, although earlier introduction may lead to earlier seroconversion and CD. In observational studies involving cohorts with a known risk for CD, consuming a high amount of gluten compared to a low amount during weaning and in the subsequent childhood years-specifically the first 2-3 years, and even up to 5 years in some studies-was associated with an increased risk for CD. However, the specific optimal amounts of gluten consumption remain undetermined due to insufficient evidence on safe thresholds, and the impact of restricting gluten in the diet of healthy children of unknown risk for CD is unknown. Thus, any recommendation on the gluten amount is currently unjustifiable for the general population and infants with known HLA risk types. There is no specific guidance on the type of gluten-containing foods to be introduced at weaning.

Increasing Maternal Anxiety in the Pre- to Postpartum Transition Predicts Infant Feeding Practices and Beliefs

OBJECTIVE

Anxiety symptoms increase for some mothers in the perinatal period. Little is known about how increasing anxiety relates to infant feeding beliefs or weight-for-length. We examined relationships between clinically meaningful increases in maternal anxiety symptoms and perceptions of infant feeding behaviors and weight-for-length.

METHODS

Participants were 237 mothers with singleton pregnancies enrolled from obstetric care between 2015 and 2020 who completed the Infant Feeding Questionnaire (IFQ) at 6 months. Anxiety symptoms were measured during pregnancy (M = 24.6 weeks, SD = 6.3) and 6 weeks postpartum using the PROMIS-6A. Linear regression was used to test associations of prenatal, postpartum, or clinically meaningful increases in anxiety symptoms (ie, 3T-score increase) with two outcomes: IFQ (seven factors) and infant weight-for-length at age 6 months.

RESULTS

Prenatal symptoms were unrelated to IFQ factors. Postpartum symptoms predicted IFQ factors related to worry, such as concern for infant undereating/becoming underweight (B = 0.012, P = .02). Increasing symptoms predicted worry-related concerns as well as concern for infant hunger (B = 0.60, P ≤ .01) and greater preference for feeding on a schedule (B = 0.65, P ≤ .01). In a model including both increasing symptoms and postpartum symptoms, increasing anxiety symptoms drove associations with IFQ factors (eg, preference for feeding on a schedule, (B = 0.81, P = .01). Anxiety was unrelated to infant weight-for-length at 6 months.

CONCLUSIONS

Clinically meaningful increases in anxiety symptoms were associated with feeding beliefs related to worry. Increasing anxiety was a better predictor of feeding beliefs than the presence of pre- or postpartum symptoms alone. Mothers with increasing anxiety may benefit from support establishing health-promoting infant feeding practices.

Food texture experiences across nine age groups in Indian infants from urban areas

The introduction of complementary food plays a fundamental role in dietary behaviours later in life. Little is known about the influences of age on food texture acceptance in young Indian children. Thus, the objective of this cross-sectional study was to describe the relationship between age and food texture experiences in young children aged 4-36 months in India from urban areas using a parental-reported survey. This study relies on a face-to-face parent survey, which was conducted comprising 306 children categorised into 9 age groups. Questions focussed on food texture experience considering 16 textures were analysed. Textures such as dissolvable, sticky, and soupy/liquidy were already accepted by more than half of 4-5-month-old infants. In India, soupy/liquidy is a more common base texture than pureed. Indeed, pureed was found to be introduced to a majority of infants only from 8 to 9 months onwards. Food textures such as rubbery, slippery, and foods with skin were more likely rejected by the youngest children. With increasing age, the refusal probability of food textures decreased. Our survey showed food texture experiences in Indian children aged from 4 to 36 months. It provides useful insights for parents and healthcare professionals by contributing to the understanding of texture acceptance during the transition to complementary foods.

Clinically Relevant Topics and New Tendencies in Childhood Nutrition during the First 2 Years of Life: A Survey among Primary Care Spanish Paediatricians

A multicenter cross-sectional study was conducted among 245 experienced Spanish paediatricians, who completed an online survey based on clinically relevant topics in nutrition during the first two years of life and their recommendations to parents in daily clinical practice. Most participants advise about the choking risk associated with baby-led weaning (BLW) and more than 60% consider that infants can receive an insufficient variety and quantity of nutrients with this practice. The general opinion is that there is a lack of evidence for delaying the introduction of gluten and other allergenic foods in the complementary feeding of healthy infants. Most participants agree/strongly agree that two servings of dairy products are the adequate daily amount in a diversified diet and 93.4% disagree/strongly disagree with the use of vegetal beverages under 1 year of life. There is a general agreement to avoid added salt and sugar before 12 months of life, the consideration that organic foods do not have a better nutritional profile than non-organic ones, and the limitations of vegetarian diets especially for adequate provision of micronutrients. Overall, there is an adequate knowledge of the new trends by paediatricians and younger ones seemed more in favor of them and interested in receiving more information on most topics.

Infant formulas for the treatment of functional gastrointestinal disorders: A position paper of the ESPGHAN Nutrition Committee

Functional gastrointestinal disorders (FGID), such as infant regurgitation, infant colic, and functional constipation, are common and typically physiological phenomena during the early months of an infant's life and account for frequent consultations with pediatricians. Various infant formulas are marketed for their management and are frequently given by parents to infants before a medical consultation. However, the evidence supporting their effectiveness is limited and some have altered nutritional compositions when compared to standard formulas. Thus, these products should only be used under medical supervision and upon medical advice. Marketing and over-the-counter sales do not ensure proper medical guidance and supervision. The aim of this position paper is to review the current evidence regarding the safety and efficacy of formulas specifically formulated for addressing regurgitation, colic, and constipation, recognized as FGID. The objective is to provide guidance for clinical management based on the highest quality of available evidence. A wide search using Pubmed, MEDLINE, EMBASE and Cochrane Database of Systematic Reviews was performed including the MESH terms infant formula, colic, constipation, regurgitation, reflux, palmitate, lactase, lactose, magnesium, hydrolyzed protein, prebiotics or probiotics. 752 papers were identified and screened. Finally, 72 papers were included in the paper. In the absence of evidence, recommendations reflect the authors' combined expert opinion. Final consensus was obtained by multiple e-mail exchange and meetings of the Nutrition Committee. (1) For breastfed infants experiencing FGID such as regurgitation, colic, or constipation, transitioning from breastfeeding to commercial formulas is not recommended. (2) In general, whether an infant is breastfed or formula-fed, it's crucial to reassure parents that FGIDs are normal and typically do not necessitate treatment or change to a special formula. (3) Thickened formulas, often termed anti-reflux formulas, may be considered in specific cases of regurgitation. (4) The usage of specialized formulas for infants with colic is not advised due to a lack of clinical evidence. (5) In the case of constipation in infants, the use of formulas enriched with high β-palmitate and increased magnesium content may be considered to soften the stool. Generally, there is limited evidence supporting the use of specialized formulas for FGID. Breastfeeding should never be discontinued in favor of formula feeding.

World Health Organization (WHO) guideline on the complementary feeding of infants and young children aged 6-23 months 2023: A multisociety response

The recent World Health Organization (WHO) guideline aims to provide evidence-based recommendations on complementary feeding (CF) of healthy term infants and young children 6-23 months living in low-, middle-, and high-income countries, including both breastfed and non-breastfed children. Like WHO, our organizations aim to promote optimal infant and young child nutrition and health, with a focus on promoting breastfeeding as well as appropriate and timely CF. In this paper, we share our concerns about aspects of the guideline, some of which may have the potential to cause unintended harm in infants and young children and suggest alternative or modified proposals.

Stability of child appetitive traits and association with diet quality at 5 years and 9-11 years old: Findings from the ROLO longitudinal birth cohort study

BACKGROUND

We explored change in child appetitive traits from 5 to 9-11 years old and examined associations between appetitive traits at both timepoints and child diet quality.

METHODS

This is secondary analyses of the ROLO longitudinal birth cohort study, including mother-child dyads from the 5 and 9-11-year old follow-up. The Children's Eating Behaviour Questionnaire measured child appetitive traits, with 167 children having matched data for both timepoints. The Healthy Eating Index (HEI) measured diet quality. Linear mixed models and multiple linear regression were completed.

RESULTS

Mean (SD) score for 'Emotional Overeating' (1.63 (0.51) vs. 1.99 (0.57), p = <0.001) and 'Enjoyment of Food' (3.79 (0.72) vs. 3.98 (0.66), p = <0.001) increased from 5 to 9-11 years. Mean score for 'Desire to Drink' (2.63 (0.94) vs. 2.45 (0.85), p = 0.01), 'Satiety Responsiveness (3.07 (0.66) vs. 2.71 (0.66), p = <0.001), 'Slowness Eating' (3.02 (0.77) vs. 2.64 (0.78), p = <0.001), and 'Food Fussiness' (3.00 (1.04) vs. 2.81 (0.96), p = 0.001) decreased. At 5-years-old, 'Food Responsiveness' and 'Enjoyment of Food' were positively associated with HEI and 'Desire to Drink', 'Satiety Responsiveness' and 'Food Fussiness' were negatively associated with HEI. At 9-11-years, 'Enjoyment of Food' was positively and 'Desire to Drink' and 'Food 'Fussiness' were negatively associated with HEI.

CONCLUSIONS

Food approach appetitive traits increased over time, whereas food avoidant appetitive traits tended to decrease. At both time points 'Food Fussiness' and 'Desire to Drink" were inversely associated with HEI. Further research on how appetitive traits track over childhood and how this relates to dietary quality and weight is warranted.

Associations between breastfeeding duration and adherence to complementary feeding recommendations in Scotland

We aimed to describe how breastfeeding relates to adherence to complementary feeding (CF) recommendations, diet diversification and feeding skills development and whether sociodemographic factors explain any differences observed. The Scottish Maternal Infant and Nutrition Survey for infants aged 8-12 months collected breastfeeding history, CF practices, diet and sociodemographic data using a self-completion questionnaire. Non-healthful CF practices were starting CF < 6 months, any consumption of sugar-sweetened beverages (SSBs), sweet or salty snacks (treats) or unmodified cow's milk and regular consumption of commercial baby foods. Diet diversification and feeding skills were assessed by amount of self-feeding and number of food groups, meals and snacks eaten daily. Of the 2730 mothers, 20% were solely infant formula fed (IFF) and 48% continued breastfeeding ≥6 months. Compared to IFF babies, mothers who gave any breast milk ≥6 months were more likely to start CF ≥ 6 months compared to those IFF (66% vs. 37%) and less likely to give treats (15% vs. 45%), SSBs (11% vs. 20%) and commercial baby foods (31% vs. 53%). These associations remained highly significant (p < 0.001) even after sociodemographic factor adjustment. Despite starting CF later, infants breastfed ≥6 months ate the same number of food groups and meals as those IFF, were just as likely to self-feed purees and more likely to self-feed finger foods daily (87% vs. 81% p < 0.001). Mothers who breastfeed beyond 6 months adhere more to CF recommendations and start CF later compared to IFF, but their babies eat a similarly diverse diet and have similar feeding skills.

Complementary feeding practices of caregivers of infants with Down syndrome as compared to caregivers of typically developing infants

Caregiver feeding practices during the complementary feeding period (6 months-2 years) may be particularly important for infants with Down syndrome (DS) as they are at higher risk for later health conditions (e.g., obesity, diabetes) that can be influenced by early feeding practices. However, how well caregivers of infants with DS are meeting infant feeding evidence-based practices is relatively unknown. Caregivers of infants with DS (N = 75) and caregivers of typically developing (TD) infants (N = 66) aged 0-2 years completed an online survey about their infant feeding practices and information sources. Caregiver practices and information sources were statistically compared between groups. Results indicated that there are significant differences in the feeding practices of caregivers of infants with DS when compared to caregivers of TD infants. Caregivers of infants with DS were less likely to meet infant feeding evidence-based practices than caregivers of TD infants. Caregivers of infants with DS were also more concerned about their infant's food intake and later weight status. Some individual feeding practices also significantly differed between groups, with caregivers of infants with DS more likely to meet evidence-based practices of purchasing iron rich foods and avoiding added salt, but less likely to use responsive feeding practices than caregivers of TD infants. Caregivers of infants with DS were also less likely to receive information about how to navigate the complementary feeding period than caregivers of TD infants. Coupled with existing research, the results of the present study suggest that infant feeding evidence-based practices should be reviewed for their appropriateness for this population and additional support for caregivers of infants with DS should be implemented to help them navigate this important period.

Introduction of Solid Foods in Preterm Infants and Its Impact on Growth in the First Year of Life-A Prospective Observational Study

The aim of this study was to investigate whether age at introduction of solid foods in preterm infants influences growth in the first year of life. This was a prospective observational study in very low birth weight infants stratified to an early (<17 weeks corrected age) or a late (≥17 weeks corrected age) feeding group according to the individual timing of weaning. In total, 115 infants were assigned to the early group, and 82 were assigned to the late group. Mean birth weight and gestational age were comparable between groups (early: 926 g, 26 + 6 weeks; late: 881 g, 26 + 5 weeks). Mean age at weaning was 13.2 weeks corrected age in the early group and 20.4 weeks corrected age in the late group. At 12 months corrected age, anthropometric parameters showed no significant differences between groups (early vs. late, mean length 75.0 vs. 74.1 cm, weight 9.2 vs. 8.9 kg, head circumference 45.5 vs. 45.0 cm). A machine learning model showed no effect of age at weaning on length and length z-scores at 12 months corrected age. Infants with comorbidities had significantly lower anthropometric z-scores compared to infants without comorbidities. Therefore, regardless of growth considerations, we recommend weaning preterm infants according to their neurological abilities.

Complementary feeding approaches and risk of choking: A systematic review

There are two main complementary feeding (CF) approaches: traditional spoon-feeding (TSF) and baby-led weaning (BLW). Many parents and healthcare professionals have concerns about the risk of choking associated with BLW. Since asphyxia is one of infants' main causes of death, this study aims to understand the influence of the CF approach adopted by caregivers on infants' risk of choking. A systematic review was performed. The search was conducted through PubMed, Scopus, and Web of Science databases. We included randomized controlled trials or observational studies published between January 2010 and November 2023, with a clear definition of the intervention and directly assessing the risk of choking. After the selection procedure, 7 of the 165 studies initially identified were included. No study reported statistically significant differences in the risk of choking between babies following BLW, baby-led introduction to solids (BLISS), and TSF. In five studies, although not statistically significant, infants in the TSF group had more choking episodes than those in the BLW or BLISS groups. The risk of choking does not seem to be associated with the CF approach. Instead, it may be related to the familiarity of the baby with each texture and the parent's understanding of the information about how to minimize the risk of choking. Recall bias may be present in all included studies. Advice on how to modify foods to make them safer needs to be clearer and reinforced to all parents.

A Descriptive Study of Spanish and Ecuadorian Commercial Infant Cereals: Are They in Line with Current Recommendations?

Cereals are an important source of nutrients, especially used in complementary feeding. The objective of this study is to review the nutritional composition of cereal-based foods for infants from 4 months and toddlers that are offered in Spain and Ecuador, countries selected because of the opportunity to work in them, and due to their socio-economic differences (industrialized and developing countries, respectively). The number of these products was 105 cereals in Spain and 22 in Ecuador. The products were classified as gluten-free cereals, five cereals, eight cereals, multigrain cereals, and cookies. A 25 g serving was used to determine the percentage in which the samples analyzed can cover the Reference Nutrient Intake (RNI) for micronutrients in infants from 7 months and toddlers according to the European Food Safety Authority (EFSA). Nutritional information per 100 g of dry product was collected according to medium, minimum, and maximum units, and nutrient density was calculated. The age range in which these products are recommended is different in both countries. The nutritional composition presents some differences; Spanish cereals show a lower content of sodium, added sugars, hydrolyzed cereals, and maltodextrin than Ecuadorian cereals. Commercialized cereals could contribute to satisfying the nutritional needs of infants and toddlers; however, they can also be a source of non-recommended components.

Early feeding practices and eating behaviour in preschool children: The CORALS cohort

This study aimed to investigate if the duration of breastfeeding and the method at initiation of complementary feeding affect eating behaviour in children aged 3-6 years. This is a cross-sectional analysis from the Childhood Obesity Risk Assessment Longitudinal Study project, an ongoing longitudinal cohort study that aims to identify childhood obesity risk factors in Spanish children. A total of 1215 children aged 3-6 years were included. Breastfeeding duration and the method of initiation of complementary feeding [baby-led weaning (BLW), traditional/spoon or mixed method] were evaluated. Eating behaviour at 3-6 years was assessed with the Child Eating Behaviour Questionnaire. Generalized linear models were fitted to assess the association between the aforementioned exposures and eating behaviour. Children breastfed for ≥4 months were less likely to be fussy eaters at 3-6 years compared to those breastfed for <1 month (OR: 0.86 95% CI: 0.76-0.98; p = 0.031). Compared to those children using the traditional/spoon-feeding method, those initiating complementary feeding through BLW or through a mixed approach were more likely to have higher scores on the enjoyment of food (EF) (OR, 95% CI: 1.33, 1.13-1.57; p = 0.001 and 1.17, 1.05-1.30; p = 0.002, respectively) and lower scores on food fussiness (FF) at 3-6 years (0.76, 0.62-0.91; p = 0.004 and 0.87, 0.78-0.98; p = 0.033, respectively). Breastfeeding for ≥4 months and initiation of complementary feeding with the BLW and a mixed approach were associated with greater EF and lower FF, which should endure practice.

Factors impacting complementary feeding advice given by paediatricians in Cyprus

BACKGROUND

Complementary feeding has long-term effects on health but there is heterogeneity in recommendations across Europe. Recommendations include responsive feeding practices and nutritional needs but there is a debate in primary paediatricians as to which one should be the main criterion for complementary feeding. This pilot study investigated (i) the factors affecting the recommendations of paediatricians in Cyprus for starting complementary feeding, (ii) whether their main criterion is the developmental readiness or the nutritional needs of the infant and (iii) how this priority influences recommendations.

METHODS

The 11-item questionnaire was completed by 73 Cypriot paediatricians.

RESULTS

Approximately 66% of paediatricians recommended starting complementary feeding between 5 and 6 months, 29% between 4 and 5 and 3% between 6 and 7 months. Predefined schemes were recommended by ∼25% of paediatricians, baby-led weaning by 14% and 58% of paediatricians recommended either modality depending on the family circumstances whilst 4% involve the mother in the decision process. Approximately 64% of paediatricians recommended the introduction of parent's diet after the first year of life. Approximately 55% of paediatricians chose developmental readiness and 45% nutritional needs of the infant as their primary criterion for starting complementary feeding. Paediatricians who prioritized developmental readiness were more likely to be younger, less likely to advice on meat quantity and less likely to follow good nutritional practice.

CONCLUSIONS

The younger the paediatrician the more likely they are to prioritize developmental readiness over nutritional needs of the infant for complementary feeding. Paediatricians who prioritized developmental readiness were also less likely to provide nutritional advice.

Development of eating skills in infants and toddlers from a neuropediatric perspective

Early infant feeding and swallowing are complex motor processes involving numerous muscles in coordination, e.g. the orofacial muscles as well as the muscles of the pharynx, larynx and esophagus. The newborn's reflexive drinking develops into the ability to ingest pureed complementary food as infancy progresses. Finally, in the last part of the first year of life, a differentiated eating, chewing and swallowing process develops allowing the voluntary intake of different foods of the family diet. The dietary schedule for the first year of life, which describes the recommended nutrition of infants in Germany, corresponds to these milestones in eating development. Disturbances in gross motor development, sensory processing issues, and organic and behavioral problems are known to interfere with the development of eating skills. Swallowing disorders (dysphagia) in children can have a detrimental effect on food intake and pose a serious risk to growth and development. Their prevention treatment requires a multidisciplinary approach with the aim of enabling the child to eat independently in the long term.

Pediatric Intestinal Failure Associated Eating Disorder: An Overview of the Importance of Oral Feeding in a Population at Risk for Feeding Difficulties

Achieving feeding skills and food acceptance is a multi-layered process. In pediatric intestinal failure (PIF), oral feeding is important for feeding skills development, physiologic adaptation, quality of life and the prevention of eating disorders. In PIF, risk factors for feeding difficulties are common and early data suggests that feeding difficulties are prevalent. There is a unique paradigm for the feeding challenges in PIF. Conventional definitions of eating disorders have limited application in this context. A pediatric intestinal failure associated eating disorder (IFAED) definition that includes feeding/eating skills dysfunction, psychosocial dysfunction, and the influence on weaning nutrition support is proposed.

Potential Micronutrient Deficiencies in the First 1000 Days of Life: The Pediatrician on the Side of the Weakest

PURPOSE OF REVIEW

This study is to examine potential micronutrient deficiencies and any need for supplementation in children following specific diet plans in the first 1000 days of life.

RECENT FINDINGS

Optimal nutrition in the first 1000 days of life has a lifelong positive impact on child development. Specific intrauterine and perinatal factors, pathological conditions, and dietary restrictions can represent potential risk factors for micronutrient deficiencies in the first 1000 days of life, which can have negative systemic consequences. Preterm and low-birth-weight infants are intrinsically at risk because of immature body systems. Children affected by cystic fibrosis are prone to malnutrition because of intestinal malabsorption. The risk of micronutrient deficiency can increase in various situations, including but not limited to children following selective dietary regimens (vegetarian and vegan diets and children affected by specific neuropsychiatric conditions) or specific dietary therapies (children affected by food allergies or specific metabolic disorders and children following restricted diet as a part of therapeutic approach, i.e., ketogenic diet for epilepsy). In light of this situation, the micronutrient status in these categories of children should be investigated in order to tailor strategies specific to the individual's metabolic needs, with a particular focus on deficiencies which can impair or delay the physical and cognitive development of children, namely, vitamin B12, vitamin D and folic acid, as well as oligo-elements such as iron, zinc, calcium, sodium, magnesium, and phosphorus, and essential fatty acids such as omega-3. Identification of micronutrient deficiency in the first 1000 days of life and timely supplementation proves essential to prevent their long-term consequences.

Relationship between prematurity and difficulties in the transition of food consistency in childhood: a systematic review

PURPOSE

To systematically review the literature regarding the impact of prematurity on the transition of food consistencies in infants during the introduction of complementary feeding.

RESEARCH STRATEGIES

Searches were conducted in the EMBASE, Latin American and Caribbean Literature in Health Sciences (LILACS), LIVIVO, PubMed/Medline, Scopus, and Web of Science databases, Google Scholar; for gray literature, searches were conducted on Open Gray, and ProQuest Dissertations & Theses databases, from August 10, 2020, onwards.

SELECTION CRITERIA

"PECOS" was selected to determine inclusion criteria: Population (P): Infants; Exposure (E): Prematurity; Comparison (C): Full-term newborns; Outcomes (O): Progression of food consistencies in premature newborns with or without comparison; Study design (S): Cohort study, Case-control; Cross-sectional.

DATA ANALYSIS

The methodological quality of the selected observational studies was assessed using the Meta-Analysis of Statistics Assessment and Review Instrument (MASTARI).

RESULTS

A total of 3,310 articles were found, of which nine were selected for qualitative synthesis. Among the selected studies, a relationship between invasive oral interventions and feeding difficulties was observed for all assessed skills, with feeding difficulties being more frequent in infants with lower gestational age.

CONCLUSION

Most studies found no significant relationship between prematurity and difficulties in the progression of food consistencies during the introduction of complementary feeding; only three studies demonstrated such a relationship.

Preterm Infants on Early Solid Foods and Neurodevelopmental Outcome-A Secondary Outcome Analysis of a Randomized Controlled Trial

There are no evidence-based recommendations regarding the introduction of solid foods in preterm infants. The objective of this study was to investigate whether age at the introduction of solid foods affects neurodevelopmental outcomes. This study focuses on analyzing secondary outcomes from a prospective trial involving very low birth weight infants who were randomly assigned to either an early (10-12th week corrected age) or a late (16-18th week corrected age) complementary feeding group. The study evaluated neurodevelopmental outcomes at one and two years of corrected age, as well as at three years and four months of uncorrected age by utilizing Bayley scales. In total, 89 infants were assigned to the early and 88 infants to the late group, all with a mean gestational age of 27 + 1 weeks. A linear mixed-effects model was used to compare neurodevelopmental outcomes across the study groups, taking into account variables such as gestational age at birth, sex, nutrition at discharge, parents' highest education level, and high-grade intraventricular hemorrhage. The analysis did not reveal any significant differences between the groups. The timepoint of the introduction of solid foods had no impact on neurodevelopmental outcomes at one and two years of corrected age, and at three years and four months of uncorrected age.

Use of Different Iron Preparations for Prophylaxis and Effects on Iron Status in Infancy

Aim: To evaluate using different iron preparations for iron deficiency and/or iron deficiency anemia prophylaxis in infants and their iron status. Methods: In this study, we retrospectively evaluated the electronic patient records of 651 healthy children aged 9 to 13 months who met the inclusion criteria and who were followed up in pediatric follow-up outpatient clinics between January 2023 and June 2023. Results: A total of 651 children with a mean age of 11.2 ± 1.4 months, 54.7% of whom were boys, who met the inclusion criteria were included in the study; 56.5% of the children were using Fe + 3 salt and the others were using Fe + 2 salt, microencapsulated iron, or sucrosomial iron drops. After the fifth month of prophylaxis, when the effects of the iron preparations used on the mean laboratory values were evaluated, it was found that hemoglobin, serum iron, and ferritin levels were lower in sucrosomial iron and microencapsulated iron users compared to other preparations (p = 0.001). When statistically pairwise comparisons were made between the groups, hemoglobin and serum iron values were found to be lower in the group using sucrosomial iron compared to the groups using Fe + 2 and Fe + 3 salts (p < 0.0001). Hemoglobin and ferritin levels were higher in the group using Fe + 2 salt compared to both sucrosomial iron and microencapsulated iron groups (p < 0.0001). When the infants were evaluated according to iron status, it was found that 208 (31.9%) had iron deficiency. Iron deficiency was found to be less in infants of families who defined their economic status as rich and in infants who used iron regularly (p-values 0.044 and 0.001, respectively). Iron deficiency/iron deficiency anemia was observed at a higher rate in the group using sucrosomial iron and microencapsulated iron prophylaxis (p = 0.001). Conclusions: To prevent iron deficiency, it is very important to use appropriate iron preparations for prophylaxis and to feed foods with high iron content. Although we found that families were willing to use different iron preparations other than iron salts for their infants, the results presented herein indicate that the rate of iron deficiency was lower in patients using iron salts. However, randomized controlled studies are needed to determine whether these preparations are effective in iron prophylaxis in infants.

Breastfeeding Duration Is Not Associated With Offspring Inflammatory Bowel Disease Risk in Three Population-Based Birth Cohorts

BACKGROUND & AIMS

Breastfeeding is critical for offspring health and development. Although many observational studies report a protective effect between breastfeeding and inflammatory bowel disease (IBD), the relationship is not well-understood.

METHODS

We used prospectively collected data from 3 population-based birth cohorts (Danish National Birth Cohort, Norwegian Mother, Father, and Child Cohort, and All Babies in Southeast Sweden) and cross-linked national registers to ascertain the impact of breastfeeding duration on offspring IBD risk in each country, using adjusted Cox proportional regression analyses. We performed meta-analyses to determine pooled estimates.

RESULTS

We included 148,737 offspring and 169,510 offspring in analyses of exclusive and any breastfeeding duration, respectively. During median follow-up of 16.3-22.3 years, between 1996 and 2021, 543 offspring were diagnosed with IBD. In each country, there was no association between exclusive breastfeeding duration and offspring IBD risk after adjusting for birth year (Denmark), offspring sex, parental IBD status, maternal education, smoking during pregnancy, age at delivery, mode of delivery, preterm birth, and small for gestational age. The pooled adjusted hazard ratio for IBD was 1.24 (95% confidence interval, 0.94-1.62; Q = 0.16, I2 = 0.0%) and 1.02 (95% confidence interval, 0.85-1.21; Q = 1.45, I 2= 0.0%) among offspring breastfed exclusively for ≥6 months and <4 months, respectively, compared with 4-5 months. Similarly, we found null associations in pooled analyses of any breastfeeding duration and IBD, subtypes Crohn's disease and ulcerative colitis, as well as in cohort-specific analyses.

CONCLUSIONS

In prospectively collected data from 3 population-based birth cohorts, the duration of exclusive or any breastfeeding was not associated with offspring IBD risk.

Metabolomics in Children Cow's Milk Protein Allergy: Possible Contribution from a System Biology Approach?

One of the most frequent triggers of food anaphylaxis in pediatric age but also among the most common, early, and complex causes of childhood food allergy is cow's milk protein allergy (CMPA). The diagnostic course and management of this allergy is defined in a complex clinical picture due to several factors. First of all, the epidemiological data are not uniform, mainly as a consequence of the diagnostic methodology used in the various studies and the different age ranges covered. In addition, there is the complexity of terminology, since although CMPA traditionally refers to immune-mediated reactions to cow's milk, it is a term encompassing numerous clinical features with different symptoms and the requirement for specific treatments. Moreover, the differential diagnosis with other very frequent diseases, especially in the first year of life, such as gastro-esophageal reflux disease or colic, is still complex. This can result in misdiagnosis and incorrect treatment, with harmful health consequences and significant economic repercussions. In this context, the combination of several omics sciences together, which have already proved useful in clarifying the allergenicity of cow's milk proteins with greater precision, could improve the diagnostic tests currently in use through the identification of new, more specific, and precise biomarkers that make it possible to improve diagnostic accuracy and predict the patient's response to the various available treatments for the recovery of tolerance.

Sociocultural context of exclusive breastfeeding in Africa: A narrative review

Background and Aims

Although exclusive breastfeeding (EBF) has many benefits, it is not commonly practiced in several countries as a result of context-specific challenges. EBF practice is thus a global health discourse because over 200 million children suffer from malnutrition despite the abundance of human milk. The risk of starvation remains very high among African children with less than 40% of them exclusively breastfed. In Africa, the adoption or nonadherence to EBF is a sociocultural issue. Hence, this narrative review examined the sociocultural context of EBF in the region.

Methods

PubMed, Google Scholar, and Scopus were searched using keywords related to EBF and Africa. Relevant data from selected studies were synthesized narratively and reported using a structured narrative format.

Results

EBF is strongly rooted in every culture and is a culturally determined behavior. Some believe that colostrum is dirty and harmful to newborns and, thus, needs to be purified. Despite the belief that human milk is the best food for babies, mothers often complement human milk with other foods right from birth because of perceived lactation inadequacy. Most African mothers believe in prelacteal feeding to help cleanse the infant's gastrointestinal tract for digestion, quench thirst, flush the bladder and help the mother to rest after childbirth before breastfeeding (BF) is initiated. The role of significant others was equally found important in the decision and duration of BF. The availability of family support (especially from grandmothers and husbands) reportedly encouraged EBF in Africa. The duration and exclusivity of BF in Africa are negatively associated with demographic variables like young age, low level of education, being unmarried, low income, out of employment, and parity (first-time mother).

Conclusion

While there have been some efforts and policies to improve EBF, it is important to consider context-specific challenges and sociocultural factors. There is a need for more deliberate efforts to encourage mothers through the implementation of effective best practices concerning EBF in Africa.

Breastmilk mineral composition among well-educated mothers from Central Poland - Associations with maternal dietary intake, dietary patterns and infant psychomotor development

BACKGROUND

Maternal dietary habits could affect breastmilk mineral composition, which may influence infant development. Mineral dietary intake or supplementation slightly affects its breastmilk concentration. However, the intake of selected food groups or dietary patterns that reflect diet complexity could have a greater impact. Hence, the aim of the study was to assess breastmilk mineral composition at one, three, and six months of lactation among mothers living in urban area of Central Poland, as well as the evaluate maternal dietary determinants and associations with infant anthropometric and psychomotor development.

METHODS

The study was conducted among 43 healthy and exclusively breastfeeding mothers. In the first, third, and sixth months of lactation, we collected breastmilk samples and assessed the concentration of Ca, P, Zn, Fe, Se, Ni, As, Pb, and Cd using the ICP-MS method. Maternal dietary habits were evaluated by a food frequency questionnaire in the first month of lactation, whereas in the third and sixth by the three-day food record. Based on the collected data adherence to the Polish-adapted Mediterranean (Pl-aMED; 1 month) and the DASH diet (Mellen's Index; 3 and 6 months) was assessed. In the third and sixth months of lactation infant anthropometric parameters and the sixth month of lactation psychomotor development were evaluated.

RESULTS

Breastmilk Se, Ni, As, Pb, and Cd levels were under the LOQ in all the breastmilk samples at all study visits. Median breastmilk mineral concentrations of Ca, P, Zn, and Fe in the first, third, and sixth months of lactation varied from 381.9 to 332.7 mg/L, 161.6 to 139.1 mg/L, 2.2 to 0.8 mg/L, and 0.26 to 0.17 mg/L, respectively. Maternal dietary intake and supplementation did not affect breastmilk Ca, P, Zn, and Fe. Pl-aMED scores were associated with breastmilk Ca (β = 0.489, 95% CI 0.180 - 0.799, p = 0.003) and Zn (β = 0.499, 95% CI 0.199 - 0.798, p = 0.002) in the first month of lactation, whereas no association with the DASH diet were observed in the third and sixth month of lactation. Breastmilk Fe in the third month was associated with infant motor development (β = 0.420, 95% CI 0.113 - 0.727, p = 0.009) in the sixth month of life, but no other associations with anthropometric or psychomotor development were observed. Moreover, we estimated that few infants meet their adequate intake (AI) requirements for P, Zn, and Fe.

CONCLUSION

Our study showed that maternal adherence to Pl-aMED is a significant predictor of breastmilk Ca and Zn in the first month of lactation, which may be especially important considering that more than 75% of infants had inadequate Zn intake. Moreover, we found that breastmilk Fe positively influenced infant motor development, despite the majority of infants having inadequate intake. On the other hand, no infant had deficiency symptoms, which emphasizes the necessity to evaluate of AI norms for infants.

Working with companies that manufacture breastmilk substitutes: An EAACI position paper

Breastmilk is the optimal source of nutrition for infants and should ideally be provided exclusively for the first 6 months of life, and alongside complementary food until 2 years of life. However, there are circumstances where a breastmilk substitute (BMS) may be required. This includes maternal and/or child conditions or personal preference. Whilst these circumstances should never be used as an opportunity to promote BMS, healthcare professionals (HCPs) need to have the knowledge of suitable alternatives and should always be guided by scientific and health motives when recommending a BMS. The Task Force 'Milk Formula Industry Sponsorship' from the European Academy of Allergy and Clinical Immunology (EAACI), provides with this publication recommendations for EAACI interactions with the BMS manufacturers and how this will be supervised.

Junk food use and neurodevelopmental and growth outcomes in infants in low-resource settings

Introduction

Feeding infants a sub-optimal diet deprives them of critical nutrients for their physical and cognitive development. The objective of this study is to describe the intake of foods of low nutritional value (junk foods) and identify the association with growth and developmental outcomes in infants up to 18 months in low-resource settings.

Methods

This is a secondary analysis of data from an iron-rich complementary foods (meat versus fortified cereal) randomized clinical trial on nutrition conducted in low-resource settings in four low- and middle-income countries (Democratic Republic of the Congo, Guatemala, Pakistan, and Zambia). Mothers in both study arms received nutritional messages on the importance of exclusive breastfeeding up to 6 months with continued breastfeeding up to at least 12 months. This study was designed to identify the socio-demographic predictors of feeding infants' complementary foods of low nutritional value (junk foods) and to assess the associations between prevalence of junk food use with neurodevelopment (assessed with the Bayley Scales of Infant Development II) and growth at 18 months.

Results

1,231 infants were enrolled, and 1,062 (86%) completed the study. Junk food feeding was more common in Guatemala, Pakistan, and Zambia than in the Democratic Republic of Congo. 7% of the infants were fed junk foods at 6 months which increased to 70% at 12 months. Non-exclusive breastfeeding at 6 months, higher maternal body mass index, more years of maternal and paternal education, and higher socioeconomic status were associated with feeding junk food. Prevalence of junk foods use was not associated with adverse neurodevelopmental or growth outcomes.

Conclusion

The frequency of consumption of junk food was high in these low-resource settings but was not associated with adverse neurodevelopment or growth over the study period.

Cohort profile update-overview of over 35 years of research in the Dortmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study

PURPOSE

To provide an update on the cohort profile of the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study, including objectives, study design, methods and description of the comprehensive data pool, as well as to summarize the most important research findings of recent years.

METHODS

In 1985, the open (dynamic) cohort started to collect information on diet, growth, development, and metabolism of healthy children and adolescents in Dortmund, Germany. Detailed data are collected annually during infancy, childhood, and adolescence of the participants, including a 3-day weighed dietary record, a 24-h urine sample, anthropometric and medical examinations as well as interviews on lifestyle.

RESULTS

Even if the basic examination modules have not changed since the start over 35 years ago, the DONALD study has been continuously further developed by introducing new modules. As such, participants are also invited for follow-up examinations during adulthood since 2005, including an additional fasting blood withdrawal. Overall, 2375 (♂: 1177; ♀: 1198) participants were recruited in the DONALD study between 1985 and 2022. Data from ~ 30,700 anthropometric measurements, ~ 19,200 dietary records, ~ 10,600 24-h urine and ~ 1300 blood samples are available from an observation period of over 35 years.

CONCLUSION

The DONALD study provides a large data pool for longitudinal studies on nutrition, growth, and health in childhood and adolescence, its impact on the development of diseases in early adult life as well as dietary intake trends over more than three decades.

Early-childhood body mass index and its association with the COVID-19 pandemic, containment measures and islet autoimmunity in children with increased risk for type 1 diabetes

AIMS/HYPOTHESIS

The aim of this study was to determine whether BMI in early childhood was affected by the COVID-19 pandemic and containment measures, and whether it was associated with the risk for islet autoimmunity.

METHODS

Between February 2018 and May 2023, data on BMI and islet autoimmunity were collected from 1050 children enrolled in the Primary Oral Insulin Trial, aged from 4.0 months to 5.5 years of age. The start of the COVID-19 pandemic was defined as 18 March 2020, and a stringency index was used to assess the stringency of containment measures. Islet autoimmunity was defined as either the development of persistent confirmed multiple islet autoantibodies, or the development of one or more islet autoantibodies and type 1 diabetes. Multivariate linear mixed-effect, linear and logistic regression methods were applied to assess the effect of the COVID-19 pandemic and the stringency index on early-childhood BMI measurements (BMI as a time-varying variable, BMI at 9 months of age and overweight risk at 9 months of age), and Cox proportional hazard models were used to assess the effect of BMI measurements on islet autoimmunity risk.

RESULTS

The COVID-19 pandemic was associated with increased time-varying BMI (β = 0.39; 95% CI 0.30, 0.47) and overweight risk at 9 months (β = 0.44; 95% CI 0.03, 0.84). During the COVID-19 pandemic, a higher stringency index was positively associated with time-varying BMI (β = 0.02; 95% CI 0.00, 0.04 per 10 units increase), BMI at 9 months (β = 0.13; 95% CI 0.01, 0.25) and overweight risk at 9 months (β = 0.23; 95% CI 0.03, 0.43). A higher age-corrected BMI and overweight risk at 9 months were associated with increased risk for developing islet autoimmunity up to 5.5 years of age (HR 1.16; 95% CI 1.01, 1.32 and HR 1.68, 95% CI 1.00, 2.82, respectively).

CONCLUSIONS/INTERPRETATION

Early-childhood BMI increased during the COVID-19 pandemic, and was influenced by the level of restrictions during the pandemic. Controlling for the COVID-19 pandemic, elevated BMI during early childhood was associated with increased risk for childhood islet autoimmunity in children with genetic susceptibility to type 1 diabetes.

Late Preterm Newborns: Breastfeeding and Complementary Feeding Practices

BACKGROUND

The aim of this study is to identify factors associated with successful breastfeeding in late preterm infants (LPIs) and explore the initiation of complementary feeding; Methods: Prospective cohort study was conducted of infants born at 34+0 to 36+6 weeks gestational age in the Hospital of the Lithuanian University of Health Sciences Kaunas Clinics during 2020-2021. Families were followed up until the infants reached 12 months of age. Average breastfeeding initial time, average breastfeeding duration time, prevalence of exclusive breastfeeding and average solid-food feeding initiation time were examined. The correlations among factors that might affect breastfeeding rates were calculated using the chi-square test (p < 0.05); Results: In our study with 222 eligible participants, we observed a statistically significant delay in breastfeeding initiation only in the 34+0+6 gestational age group (p < 0.001). At discharge, the 36+0+6 group exhibited a significantly higher exclusive breastfeeding rate (p < 0.001). Over the first year, breastfeeding rates varied, with no correlation found between duration of exclusive breastfeeding and gestational age. Initial solid-food feeding times were similar across groups, and all infants were introduced to vegetables first; Conclusions: Vaginal delivery, skin-to-skin contact after birth, early rooming-in, and breastfeeding within 2 h after birth statistically significantly causes earlier breastfeeding initiation and longer duration of breastfeeding in LPIs. All infants began solid-food feeding at an average age of 5 months, with vegetables being the primary food choice.

Acceptance of bite presentations and feeding behaviors of 8 to 12-month-old infants: A reflection of typical feeding development

PURPOSE

The lack of age-appropriate expectations for feeding acceptance patterns in early childhood is a barrier to early and accurate identification of pediatric feeding disorder (PFD). The objective of the study was to describe the process by which typically developing children 8-12 months of age accept or refuse bite presentations and their corresponding feeding behaviors, aiming to establish age-appropriate normative data for feeding acceptance.

METHOD

Using cross-sectional methodology, we studied the proportion of bite presentations accepted, the type of feeding behaviors-passive, disruptive, expulsion, feeding concerns- observed at presentation and acceptance or refusal, and the duration between presentation to acceptance or refusal in 63 healthy infants between 8 and 12 months of age. Descriptive statistics and a one-way ANOVA were conducted to compare the effect of age and texture.

RESULTS

Findings reveal high levels of bite acceptance of 80 % or > for children across ages, but with lower texture-specific differences. Both passive and disruptive behaviors were present even during acceptance of bites without any expulsion. Feeding concerns showed developmental trends with rapid reduction by 12 months suggesting improvement in oral feeding skills. The duration of acceptance and refusals revealed clear patterns by age and texture with an average of 3 s for acceptance but <1 s for refusal.

CONCLUSIONS

This study describes bite acceptance patterns in a cohort of typically developing infants between 8 and 12 months of age by examining the acceptance of bites, frequency and type of feeding behaviors, and duration differences when children accept versus refuse a bite. Findings may be applied in the future to provide more sensitive detection of problematic feeding patterns to aid in the detection of pediatric feeding disorder.

Complementary Feeding: Tradition, Innovation and Pitfalls

According to WHO, "complementary feeding (CF) is the process starting when breast milk alone or infant formula alone is no longer sufficient to meet the nutritional requirements of infants, and therefore, other foods and liquids are needed, along with breast human milk or a breastmilk substitute". CF is one of the most important "critical and sensitive periods" in human life: indeed, timing and approaches to solid foods introduction in an infant's nutrition are of utmost importance as potential epigenetic factors from infancy to adulthood. CF is also deeply influenced by each country and single-family traditions, culture, and beliefs. The aim of our narrative review is to analyze traditional CF practices, including innovative and alternative ones that emerged in the last decades, such as baby-led weaning or plant-based weaning, and to evaluate their effects on the risk of developing non-communicable diseases. Moreover, we will discuss pitfalls and misunderstandings that pediatricians frequently have to face when dealing with complementary feeding. Health care professionals must not have prejudices against parents' wishes or traditions about CF; rather, they should support and educate them in case of any alternative CF choice, always pursuing the infant's adequate growth, neuro- and taste development, and the achievement of correct eating behavior as the primary goal.

Primary, secondary and tertiary prevention of food allergy: current practices and future directions

The incidence of food allergies has risen around the globe, and experts have been exploring methods of preventing such allergies in young children to ease the burden of disease and reduce the morbidity and mortality caused by anaphylaxis to food allergens. Such preventative measures can be categorised as primary, secondary and tertiary prevention, which are discussed in detail in this review. Primary prevention is defined as the prevention of becoming sensitised towards specific allergens. The evidence suggests that avoiding common allergenic foods during pregnancy and breastfeeding is not protective against food allergies, and guidelines recommend weaning from 4 to 6 months of age, with recent studies supporting the early introduction of peanuts at 4 months to prevent peanut allergy. Secondary prevention targets patients who are already sensitised and aims to halt the progression of sensitisation, with evidence for high rates of success and safety in trials of early introduction to milk and peanuts using oral immunotherapy in sensitised infants. Tertiary allergy prevention focuses on reducing the risk of a patient having anaphylaxis, with oral immunotherapy being the most common method of promoting tolerance in allergic children. Several studies have demonstrated successful reintroduction for milk, egg and peanut; however, no such guidelines are recommended for other foods. Finally, dietary advancement therapy in the form of milk and egg ladders has been employed as a method of primary, secondary and tertiary prevention of allergies, particularly in Ireland, the UK and Canada.

Factors associated with age of presentation of pediatric feeding disorder

AIM

Understanding the association between pediatric feeding disorder (PFD) and age of presentation is limited. We aimed to investigate factors associated with PFD among different age groups.

METHODS

Retrospective analysis of medical records of infants and toddlers diagnosed with PFD, according to the World Health Organization-based definition. We compared children aged 1-12 months to those aged 13-72 months.

RESULTS

Included were 253 children with PFD (median [interquartile range] age 16.4 [9.5-33] months at diagnosis, 56% boys). Significantly more children in the younger age group were girls (52.6% vs. 34.4%, respectively, p = .03) and preterm (25% vs. 14%, p = .03). They had more hospitalizations (34% vs. 23%, p = .03) and needed more prescription medications (36% vs. 17%, p < .01). Additionally, disturbances in oral intake were primarily linked to feeding skills dysfunction in the younger group and nutritional dysfunction in the older group (39.6% vs. 23.7% and 55% vs. 38%, respectively, p = .02).

CONCLUSIONS

Infants under 1 year old with PFD represent a distinct patient group with unique characteristics and outcomes. The age of presentation plays a significant role in children with PFD, necessitating tailored treatment strategies.

Early feeding and nutritional status of Portuguese children in the first 36 months of life: EPACI Portugal 2012-a national representative cross-sectional study

Background

Early feeding practices have a critical role in the future not only in health but also in modulating eating habits. This study aimed to assess breastfeeding and complementary feeding practices and the nutritional status of Portuguese toddlers aged 0-36 months.

Methods

EPACI Portugal 2012 is a cross-sectional study of a national representative sample. Trained interviewers collected data about early feeding practices and anthropometrics. Body mass index was classified according to World Health Organization criteria. Frequencies and survival analysis were used to characterize variables.

Results

More than 90% of children were initiated breastfeeding, around 20% were exclusively breastfed for six months, and about 20% were breastfed at 12 months while complementary feeding was taking place. Exclusive breastfeeding was determined by maternal prepregnancy body mass index (HR 1.01; 95% CI 1.00, 1.03, P=.03) and low birth weight (HR 1.61; IC 95% 1.21, 2.15, P=.001) of the infants. About 90% were initiated complementary feeding between four and six months, and almost 10% were introduced to cow's milk before 12 months. In the second year of life, 83.2% and 61.6% of toddlers have already consumed nectars and sweet desserts, respectively. About one-third of Portuguese toddlers showed a body mass index z-score >1, and 6.6% were overweight/obese (z-score >2). No association was found between the duration of breastfeeding or timing of complementary feeding and the body mass index z-score in children.

Conclusions

Despite the low prevalence of exclusive breastfeeding at six months, Portuguese infants effectively comply with dietary recommendations during the first year of life. The transition to the family diet must be carefully made. There is a high prevalence of Portuguese toddlers at least at overweight risk. The duration of breastfeeding or timing of complementary feeding was not associated with the expression of overweight/obesity.

Plant-Based Diets in Children: Secular Trends, Health Outcomes, and a Roadmap for Urgent Practice Recommendations and Research-A Systematic Review

People are increasingly encouraged to reduce animal food consumption and shift towards plant-based diets; however, the implications for children's health are unclear. In this narrative review of research in high-income settings, we summarize evidence on the increasing consumption of plant-based diets in children and update an earlier systematic review regarding their associations with children's health outcomes. The evidence indicates that vegan, but not vegetarian, diets can restrict growth relative to omnivorous children and increase the risk of being stunted and underweight, although the percentage affected is relatively small. Bone mineral content is reduced in vegetarian and, in particular, vegan children, compared to omnivores. Both vegetarian and vegan children who do not use vitamin B12 supplements manifest with B12 deficiency; however, supplementation rectifies this problem. Both vegetarians and vegans have lower concentrations of 25(OH)D if unsupplemented, and lower body iron stores, but usually have normal iron metabolism markers. Both groups are at risk of iodine deficiency, and this might affect thyroid health. Children consuming a vegan diet have a more favorable lipid profile than omnivorous children; however, the results for a vegetarian diet are inconsistent and vary by outcome. Based on the same scientific evidence, national and international dietary recommendations are heterogeneous, with some countries supporting plant-based diets among infants, children, and adolescents, and others discouraging them. We offer a research roadmap, highlighting what is needed to provide adequate evidence to harmonize dietary recommendations for plant-based diets in children. A number of measures should urgently be introduced at international and national levels to improve the safety of their use in children.

Diet Diversity During Infancy and the Prevalence of Sensitization and Allergy in Children up to 3 Years of Age in the Kujawsko-Pomorskie Voivodeship, Poland

The study examines the influence of a diversified diet, changes in the consistency of introduced foods, and the method of meal preparation during infancy on the development of sensitization and/or allergy in toddlers. Introducing more product groups into the diet reduced the risk of allergy at 6 months of age (adjusted odds ratio [aOR] = 0.17; 95% confidence interval [CI] 0.04-0.71; P = 0.015) and at 12 months (aOR = 0.14; 95% CI 0.03-0.57; P = 0.006). Children with allergy and/or sensitization had been introduced to fewer product groups at 6 months (P = 0.003; P < 0.001; P = 0.008) and at 12 months (P = 0.001, P < 0.001; P = 0.001) compared with those without allergy and/or sensitization. Children with allergy and/or sensitization were fed ready-made, ie, purchased, products significantly more often than self-prepared foods compared with children without allergy and/or sensitization (P = 0.001; P = 0.006). Allergic and/or sensitized children tended to be switched to solids later (11 vs 10 months, P = 0.041; P = 0.037) (12 vs 10 months, P = 0.013) than children without sensitization and/or allergy. The earlier introduction of a varied diet reduced the risk of allergy and/or sensitization. Delaying the introduction of solid foods and using ready-made products instead of self-prepared ones increases the risk of allergy in toddlers.

Dietary Intervention during Weaning and Development of Food Allergy: What Is the State of the Art?

Food allergy (FA) affects approximately 6-8% of children worldwide causing a significant impact on the quality of life of children and their families. In past years, the possible role of weaning in the development of FA has been studied. According to recent studies, this is still controversial and influenced by several factors, such as the type of food, the age at food introduction and family history. In this narrative review, we aimed to collect the most recent evidence about weaning and its role in FA development, organizing the gathered data based on both the type of study and the food. As shown in most of the studies included in this review, early food introduction did not show a potential protective role against FA development, and we conclude that further evidence is needed from future clinical trials.
