Impact of a modified version of baby-led weaning on iron intake and status: a randomised controlled trial

Outcome measurement instruments used to measure diet-related outcomes in infancy: A scoping review

INTRODUCTION

Supporting positive diet behaviours during infancy is essential to support child health and prevent childhood obesity. How infant diet-related outcomes are measured in trials is crucial to determining intervention effectiveness. This scoping review examined what and how outcome measurement instruments are currently used to measure 13 infant diet-related outcomes from a previously developed core outcome set.

METHODS

The databases EMBASE, MEDLINE, CINAHL and PsycINFO were searched from inception to September 2023. Eligible studies reported trials that included infants ≤1 year old and at least one diet-related outcome measurement instrument. Titles/abstracts and full texts were independently screened in duplicate. Data were narratively synthesised.

RESULTS

136 studies reporting 133 trials were included. Outcome measurement instruments used included 66 questionnaires (n = 70 studies), 65 individual questions (n = 45 studies), 24 food diaries/records (n = 21 studies), 11 24-hour dietary recall (n = 11 studies), and healthcare record data (n = 6 studies). Outcome measurement instruments were predominantly self-administered by researchers in participants homes. There was a lack of reporting for some outcome measurements used.

CONCLUSION

Review findings highlight the need to improve clarity and completeness of outcome reporting. The findings also provide an important first step to address heterogeneity in measurement of infant diet-related outcomes. Consistent measurement of diet-related outcomes is needed to improve synthesis and evaluation of obesity prevention interventions.

Baby-Led Weaning vs. Traditional Complementary Feeding-Differences in Feeding Practices Among Polish Children Aged 6-36 Months-A Cross-Sectional Study

Complementary feeding involves introducing additional foods to a child's diet, influenced by the child's age, developmental stage, and skills, such as sucking, swallowing, and chewing. The WHO and ESPGHAN recommend exclusive breastfeeding for the first six months, with the gradual introduction of complementary foods thereafter. The baby-led weaning (BLW) method emphasises self-feeding and the early introduction of solid foods, fostering independence and development. This study aimed to evaluate the mode of complementary feeding in children aged 6-36 months, considering the BLW method.

MATERIAL AND METHOD

A cross-sectional survey was conducted among the parents of children aged 6-36 months using a Google Forms questionnaire distributed through social media. The study included 1027 participants, with 1017 mother-child pairs meeting the inclusion criteria. The questionnaire covered demographic data, feeding methods, and detailed questions on complementary feeding practices, including BLW. The study included children fed using the baby-led weaning method during supplementary feeding (BLW-baby-led weaning) and children not using the BLW method (NoBLW-no baby-led weaning).

RESULTS

This study found significant differences between the BLW and NoBLW groups in terms of feeding methods and outcomes. BLW children were more often exclusively breastfed (68.9% vs. 58.7%) and started complementary feeding later (79.9% between 6 and 7 months). Adverse events in the BLW group included gagging (64.8%), spitting out food (77.1%), and choking (12.3%), with rare cases requiring medical intervention (0.2%). Children using BLW showed greater autonomy in their eating decisions and had more frequent exposure to varied food textures.

CONCLUSIONS

Children using the BLW method were more likely to be breastfed, had more contact with various textures, and were less likely to consume milk formula and pudding-type products. BLW, despite the risk of choking, is safe under supervision and supports motor development and healthy eating habits. The BLW method has the potential to support healthy eating habits and child independence, but its use requires parental education about safety and appropriate food choices. Further research should focus on the long-term effects of this method, especially in terms of its impact on children's eating habits, motor development, and health at an older age.

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.

Baby Food Pouches, Baby-Led Weaning, and Iron Status in New Zealand Infants: An Observational Study

Iron deficiency in infants can impact development, and there are concerns that the use of baby food pouches and baby-led weaning may impair iron status. First Foods New Zealand (FFNZ) was an observational study of 625 New Zealand infants aged 6.9 to 10.1 months. Feeding methods were defined based on parental reports of infant feeding at "around 6 months of age": "frequent" baby food pouch use (five+ times per week) and "full baby-led weaning" (the infant primarily self-feeds). Iron status was assessed using a venepuncture blood sample. The estimated prevalence of suboptimal iron status was 23%, but neither feeding method significantly predicted body iron concentrations nor the odds of iron sufficiency after controlling for potential confounding factors including infant formula intake. Adjusted ORs for iron sufficiency were 1.50 (95% CI: 0.67-3.39) for frequent pouch users compared to non-pouch users and 0.91 (95% CI: 0.45-1.87) for baby-led weaning compared to traditional spoon-feeding. Contrary to concerns, there was no evidence that baby food pouch use or baby-led weaning, as currently practiced in New Zealand, were associated with poorer iron status in this age group. However, notable levels of suboptimal iron status, regardless of the feeding method, emphasise the ongoing need for paying attention to infant iron nutrition.

Development and validation of the baby eating behaviour coding system (BEBECS) to assess eating behaviour during complementary feeding

Eating behaviour in children is a matter of study for which diverse tools have been designed. Coding systems for videotaped meals allow the extraction of detailed in vivo information; however, there is no tool available for infants following a Baby-Led Weaning (BLW) method. This study aimed to create and validate a new tool to assess eating behaviour in infants during weaning, applicable regardless of the complementary feeding method. The Baby Eating Behaviour Coding System (BEBECS) was developed comprising time variables, behaviours, feeder-led actions, and other meal-related variables. Sixty videos of infants aged 6-18 months following spoon-feeding (SF) or BLW methods were coded by two trained coders. These scores were analysed together with intake and maternal ratings of liking and calmness. Additionally, combined analysis and internal comparison assessed the possible differences in BEBECS variables between SF and BLW. Inter-rater and test-retest reliability had good to excellent agreement: Cohen's Kappa >0.75, Lin's CCC >0.70, and Intraclass Correlation Coefficient >0.75, for almost all variables. Infants' liking and intake of the offered food correlated positively with meal duration and total count of mouth approaches but negatively with having leftovers and time between mouth approaches. Infants' calmness and tiredness were negatively correlated. More food than initially offered was available during the meal in BLW but not in SF. There was a tendency towards more autonomous behaviour in BLW infants regarding changes observed in the time the food was in the mouth at each stage (6, 12, and 18 months). In conclusion, BEBECS has the potential to be a valid tool for application in the research of infant eating behaviour during weaning by trained coders.

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.

Estimated energy and nutrient intake in complementary feeding methods in Brazilian infants: randomized clinical trial

Inadequate nutrient intake during complementary feeding (CF) can affect healthy infant growth and development. A randomized clinical trial was conducted to examine the energy and nutrient intake in Brazilian children randomly assigned to three distinct CF methods. Mother-infant pairs participated in the study, with mothers receiving interventions in one of three CF approaches: (A) strict Parent-Led Weaning (PLW); (B) strict Baby-Led Introduction to Solids (BLISS); and (C) a mixed method. Assessments were made at 5.5 months, nine months, and 12 months of the child's age. Food consumption was measured through 24-h dietary recalls at nine and 12 months, with intake estimates calculated using the Brazilian Food Composition Table. Means or medians of energy and nutrients were compared between groups using ANOVA with Tukey's post hoc test or the Kruskal-Wallis test. A total of 115 infants were evaluated at nine months, and 102 at 12 months. Children in the PLW, BLISS, and mixed method groups exhibited comparable dietary intakes of energy, macronutrients, and micronutrients at both nine and 12 months. Infants following PLW, BLISS, and mixed methods demonstrated similar levels of energy and nutrient intake, underscoring the effectiveness of these strategies in ensuring comparable nutrient intake during the critical phase of CF.Trial registration The trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with identifier [RBR-229scm U1111-1226-9516], [ https://ensaiosclinicos.gov.br/rg/RBR-229scm ]. The full data of the first registration was on 24/09/2019.

Adherence to different complementary feeding methods in the first year of life: A randomized clinical trial

BACKGROUND

Infant-guided methods, such as Baby-Led Introduction to SolidS (BLISS), encourage children to feed themselves from the same food consumed by their family since the beginning of the introduction of complementary foods, in opposition to the Parent-Led Weaning (PLW) method, which proposes foods mashed with a fork and given by parents. Adherence to child-guided methods is low due to a lack of confidence in the children's ability to feed themselves. This study aimed to assess adherence to three methods of food introduction: PLW, BLISS, or mixed (PLW and BLISS) at seven, nine, and 12 months of age.

METHODS

A randomized clinical trial was conducted with mother-infant pairs undergoing intervention at 5.5 months of age. Data were presented in absolute numbers and percentages and analyzed using the Chi-Square test.

RESULTS

The sample was constituted of 139 mother-infant pairs: 45 (32%) used PLW, 48 (35%) used BLISS, and 46 (33%) used the mixed method. Adherence to the method at seven, nine, and 12 months of age children was 34.1% (n = 45), 28.5% (n = 37), and 34.1% (n = 46), respectively. The mixed method presented significantly higher adherence results: 69.0% (n = 29) at seven months, 55.8% (n = 24) at nine months, and 78.6% (n = 33) at 12 months (p<0.001). Among the sample that unfollowed the proposed method, those who used PLW and BLISS migrated mostly to the mixed method at 12 months, 60.0% (n = 27) and 72.9% (n = 35) of them, respectively, because of the feeding mode and 97.8% (n = 44) and 100.0% (n = 48) because of food consistency.

CONCLUSION

Complementary feeding in a mixed method presented higher adherence at seven, nine, and 12 months of age of children, which shows the feasibility of this approach to guide families in the introduction of complementary feeding.

Experiences and opinions towards baby-led weaning by healthcare professionals. A qualitative study

BACKGROUND

Baby-led weaning (BLW) is an alternative method to spoon-feeding to introduce solid foods. This study aimed to describe and understand the experiences and opinions of pediatricians and pediatric nurse specialists of the implementation of the BLW approach.

METHODS

An interpretive descriptive qualitative research was carried out. A focus group with 7 participants and 13 face-to-face interviews were conducted between February and May 2022 (17 females and 3 males). All were audio-recorded, transcribed, and analyzed with the supported by Atlas.Ti qualitative data analysis software.

RESULTS

From the data, two themes developed: (1) BLW as an ideal method of introducing solid food, with the subthemes: "a natural method of introducing complementary feeding" and "BLW is a safe method"; (2) Perceived barriers to the uptake of the BLW method, with the subthemes: "a lack of BLW training prevents the best practice" and "the influence of family and social context on parents."

CONCLUSIONS

Healthcare professionals perceive BLW to be a safe and natural weaning approach. The lack of training of healthcare professionals and the influence of family social context on parents may limit the implementation of BLW.

IMPACT

Baby-led weaning is perceived by healthcare professionals as a safe complementary feeding method that promotes chewing, improves growth, and the development of fine motor skills. However, lack of training of healthcare professionals and the family social context of the parents hinders the uptake of baby-led weaning. The views of the family and parents' social context about baby-led weaning may restrict their willingness to use the method. Family education delivered by healthcare professionals may avoid risks and allay parental anxieties about safety.

Complementary feeding approach and maternal responsiveness in 8- and 12-month-old Italian infants: A longitudinal study

In Western countries, infants are usually introduced to solids through spoon-fed puréed foods (parent-led weaning, PLW). However, an alternative approach known as "baby-led weaning" (BLW), in which infants usually participate in family meals and eat independently, is becoming increasingly popular. We investigated the relationship between the type of complementary feeding approach and maternal responsiveness to infant feeding cues in a longitudinal sample of 178 infants observed at 8 and 12 months. Mothers reported the complementary feeding method used and, from video-recorded meals, we coded the proportion of time infants self-fed and rated maternal responsiveness by means of the Responsiveness to Child Feeding Cues Scale (Hodges et al., 2013). Responsiveness to infant receptiveness and fullness cues were significantly correlated at 8 months, but not at 12 months, when unresponsiveness decreased for receptiveness but remained stable for fullness cues. Thus, as infants got older, mothers were increasingly tuned in to their receptiveness cues. However, we did not observe the same pattern for fullness cues, perhaps because mothers were concerned that their infants did not eat enough. Moreover, at both time points, mothers were more responsive to infants' receptiveness than fullness cues, possibly due to an evolutionary drive to protect infants from starvation. Finally, responsiveness to fullness, but not responsiveness to receptiveness, was positively related to the proportion of infant self-feeding, but there were no significant differences in responsiveness depending on the self-reported complementary feeding approach. Thus, a weaning style that emphasizes independent feeding, regardless of whether this is labeled as BLW, may promote more infant-centered maternal responses at the end of the meal, with potential implications for promoting infant self-regulation not only at mealtimes, but also in other domains.

The effect of baby-led weaning and traditional complementary feeding trainings on baby development

PURPOSE

The aim of this study was to evaluate the risks of self-feeding, transition to early solid food and family meals, choking risk, anemia risk and obesity risk in 6-12-month-old infants who were introduced to complementary feeding using the traditional complementary feeding (TCF) and baby-led weaning (BLW) methods/training.

DESIGN AND METHODS

Mothers of infants who had not yet transitioned to complementary feeding were included in this randomized study. The mothers of 62 infants included in the study were randomized into the intervention groups as TCF and BLW, classified according to the number of children and education level. The research was carried out according to the CONSORT-2010 guidelines after randomization and was concluded with 52 infants and their mothers.

RESULTS

It was found in the study that self-feeding and transition to solid foods in infants fed with the BLW method was higher than the infants fed with the TCF method (p < 0.05). A significant increase was observed in the hemoglobin level of infants fed with the BLW method over time (p < 0.001).

CONCLUSIONS

It was concluded that the BLW method did not lead to risks of obesity, anemia and iron deficiency in transition to complementary feeding. Secondary results indicated that feeding with the BLW method promoted self-feeding and early transition to solid foods and did not lead to the risk of choking.

PRACTICE IMPLICATIONS

Complementary feeding with the BLW method can be safely used by both mothers, healthcare professionals and researchers.

Selenium intakes and plasma selenium of New Zealand toddlers: secondary analysis of a randomised controlled trial

Little is known about Se intakes and status in very young New Zealand children. However, Se intakes below recommendations and lower Se status compared with international studies have been reported in New Zealand (particularly South Island) adults. The Baby-Led Introduction to SolidS (BLISS) randomised controlled trial compared a modified version of baby-led weaning (infants feed themselves rather than being spoon-fed), with traditional spoon-feeding (Control). Weighed 3-d diet records were collected and plasma Se concentration measured using inductively coupled plasma mass spectrometry (ICP-MS). In total, 101 (BLISS n 50, Control n 51) 12-month-old toddlers provided complete data. The OR of Se intakes below the estimated average requirement (EAR) was no different between BLISS and Control (OR: 0·89; 95 % CI 0·39, 2·03), and there was no difference in mean plasma Se concentration between groups (0·04 μmol/l; 95 % CI -0·03, 0·11). In an adjusted model, consuming breast milk was associated with lower plasma Se concentrations (-0·12 μmol/l; 95 % CI -0·19, -0·04). Of the food groups other than infant milk (breast milk or infant formula), 'breads and cereals' contributed the most to Se intakes (12 % of intake). In conclusion, Se intakes and plasma Se concentrations of 12-month-old New Zealand toddlers were no different between those who had followed a baby-led approach to complementary feeding and those who followed traditional spoon-feeding. However, more than half of toddlers had Se intakes below the EAR.

"Baby-led weaning" - Progress in infant feeding or risky trend?

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

Complementary feeding methods in the first year of life: a study protocol for a randomized clinical trial

Background

The traditional spoon-feeding approach to introduction of solid foods during the complementary feeding period is supported by consensus in the scientific literature. However, a method called Baby-Led Introduction to SolidS (BLISS) has been proposed as an alternative, allowing infants to self-feed with no adult interference. To date, there have been no trials in the Brazilian population to evaluate the effectiveness of BLISS in comparison to the traditional approach.

Methods/design

To evaluate and compare three different complementary feeding methods. Data on 144 mother-child pairs will be randomized into intervention groups by methods: (A) strict Parent-Led Weaning; (B) strict Baby-Led Introduction to SolidS; and (C) a mixed method. Prospective participants from Porto Alegre, Brazil, and nearby cities will be recruited through the Internet. The interventions will be performed by nutritionists and speech therapists, at 5.5 months of age of the child, at a private nutrition office equipped with a test kitchen where meals will be prepared according to the randomized method. The pairs will be followed up at 7, 9, and 12 months of age. Data will be collected through questionnaires designed especially for this study, which will include a 24h child food recall, questionnaires on the child’s and parents’ eating behavior, oral habits, eating difficulties, and choking prevalence. At 12 months of age, children will undergo blood collection to measure hemoglobin, ferritin, and C-reactive protein, saliva collection for analysis of genetic polymorphisms, and oral examination. Anthropometric parameters (child and maternal) will be measured at the baseline intervention, at a 9 month home visit, and at the end-of-study visit at the hospital. The primary outcome will be child growth and nutritional status z-scores at 12 months; secondary outcomes will include iron status, feeding behavior, acceptability of the methods, dietary variety, choking, eating behaviors, food preferences, acceptance of bitter and sweet flavors, suction, oral habits, oral hygiene behavior, dental caries, gingival health status, and functional constipation.

Discussion

The trial intends to ascertain whether there are potential advantages to the BLISS complementary feeding method in this specific population, generating data to support families and healthcare providers.

Brazilian health professionals' perception about the Baby-Led Weaning (BLW) method for complementary feeding: an exploratory study

Objective:

To describe Brazilian health professionals’ perception about the Baby-Led Weaning (BLW) method use for complementary feeding.

Methods:

Cross-sectional, descriptive study including 458 health professionals graduated in Nursing, Speech Therapy, Medicine, Nutrition or Dentistry and working in Pediatrics, being directly or indirectly involved with pediatric nutrition. We used a convenience non-probability sampling. The questionnaire applied to participants addressed demographic characteristics, academic degree, workplace, knowledge about clinical practice and perceptions about the possible advantages of the BLW method.

Results:

Participants had a mean age of 34.5±8.5 years, 64.6% of them working in Southeast Brazil and 65.3% being nutritionists. Most participants reported being acquainted with the BLW method (82.0%). Regarding clinical practice, 38.3% mentioned having recommended the BLW some times, 37.5% often and 20.5% always. Most participants fully agreed that the BLW method could have advantages for babies, for example, having them more likely to share family meals, facilitating adaptation to food flavors and consistencies, enhancing chewing and favoring the development of motor skills. On the other hand, important disagreements were also expressed regarding the BLW convenience and the possibility to create less concerns or anxiety in parents.

Conclusions:

The BLW method reported as advantageous, but disagreements were also raised, probably because scientific evidences on the suject are scarse. Further investigation is needed so we can better understand the risks and benefits and health care professionals can feel effectively assisted to offer support and advice to parents and caretakers.

Comparison of food and nutrient intake in infants aged 6-12 months, following baby-led or traditional weaning: A cross-sectional study

BACKGROUND

A baby-led approach to weaning (BLW) encompasses self-feeding and self-selecting graspable foods, offering an alternative to traditional weaning (TW). This cross-sectional study explored adherence to characteristics of BLW and differences in food group exposure and nutrient intake between babies following either TW or BLW.

METHODS

Nutritional data were collected via multiple-pass 24-h recall, following parental completion of an online survey.

RESULTS

Infants were grouped according to age (6-8 months; TW [n = 36] and BLW [n = 24]) and (9-12 months; TW [n = 24] and BLW [n = 12]). BLW babies were more likely to be breast fed (p = 0.002), consumed a higher percentage of foods also consumed by their mother (p = 0.008) and were fed less purees (p < 0.001) at 6-8 months. TW babies were spoon fed more (p ≤ 0.001) at all ages. Amongst babies aged 6-8 months, total intake (from complementary food plus milk) of iron (p = 0.021), zinc (p = 0.048), iodine (p = 0.031), vitamin B12 (p = 0.002) and vitamin D (p = 0.042) and both vitamin B12 (p = 0.027) and vitamin D (p = 0.035) from complementary food alone was higher in babies following TW. Compared to TW, BLW babies aged 6-8 months had a higher percentage energy intake from fat (p = 0.043) and saturated fat (p = 0.026) from their milk. No differences in nutrient intake were observed amongst infants aged 9-12 months. Few differences were observed between groups in their number of exposures to specific food groups.

CONCLUSIONS

TW infants had higher intakes of key micronutrients at 6-8 months, although there were few differences in nutritional intake at 9-12 months or food group exposure between babies following TW or BLW. BLW appears to be socially desirable. Guidance for parents is required, along with larger, longer-term studies, which explore the potential impact of BLW in later childhood.

Complementary Feeding in Italy: From Tradition to Innovation

Complementary feeding (CF) is a pivotal phase of the individual’s growth, during which children develops their future dietary habits. To date, only few studies investigated and compared weaning modalities between different geographical areas. The aim of this article is to describe the current Italian practice for CF in healthy term infants among different areas (North, Center, South) of Italy. Two different multiple-choice questionnaires were produced and sent to 665 Italian primary care pediatricians (PCP) and 2023 families with children under 1 year of age. As emerged from our investigation, in Italy CF is usually started between the 5th and 6th month of life. The preferred approach (chosen by 77% of families) involves the use of home-cooked liquid or semi-liquid ailments, or industrial baby foods. A new CF modality is emerging, consisting of traditional complementary foods with adult food tastings (10% of families). Approximately 91% of pediatricians give written dietary suggestions, and 83% of families follow their advice. We found significantly divergent weaning habits among different areas of Italy. PCP have a key role in guiding parents during the introduction of new foods in their infant’s diet and should take this as an opportunity to educate the whole family to healthy dietary habits.

Complementary Feeding Methods-A Review of the Benefits and Risks

Complementary feeding methods have the potential to not only ensure a diet of nutritional adequacy but also promote optimal food-related behaviours and skills. While the complementary feeding practice known as baby-led weaning (BLW) has gained popularity, evidence supporting the potential benefits and/or risks for infant growth, development, and health warrants consideration. A review of 29 studies was conducted with findings indicating that parents who implement BLW typically have higher levels of education, breastfeed for longer, and differ in other personality traits. Fear of choking was an important factor in parents’ decision not to implement BLW; however, this fear was not supported by the literature. Benefits of BLW included lower food fussiness, higher food enjoyment, lower food responsiveness, and higher satiety responsiveness. While this profile of eating behaviours confers a reduced obesity risk, few studies have examined the relationship between BLW and infant growth robustly. BLW does not seem to increase the risk of inadequate zinc or iron intake; however, emphasis needs to be given to ensuring adequate intake of these micronutrients among all infants. A better understanding of the impacts of BLW is needed to inform evidence-based recommendations to support and guide parents in complementary feeding methods.

Baby-led weaning in Italy and potential implications for infant development

Baby-led weaning is an approach to complementary feeding that emphasizes an infant's ability to self-feed rather than being spoon fed, and to eat minimally-processed foods rather than puréed foods. This study aimed to investigate the variability in infant feeding practices and the possible association with developmental milestones in an Italian population. A sample of 1245 mothers of 6-12 month-old infants completed an online survey about complementary feeding and their infant's attainment of developmental milestones. Infants' eating of family food was positively related to self-feeding and to a lower consumption of puréed foods. As in previous studies in the UK and New Zealand, a baby-led weaning style was positively associated with breastfeeding, exposure to complementary foods around six months of age, earlier exposure to both finger and family foods, and higher interest in family food and shared family meals. Infants who were introduced to solid foods using a baby-led weaning approach were more likely to have met important developmental milestones; when controlling for covariates, percentage of family feeding was positively associated with sitting unsupported at an earlier age and a low spoon-feeding style was associated with crawling at an earlier age. These data suggest that baby-led weaning should be defined more comprehensively. Moreover, its potential influence on developmental domains beyond diet and eating behavior warrants future targeted exploration.

Nutritional Implications of Baby-Led Weaning and Baby Food Pouches as Novel Methods of Infant Feeding: Protocol for an Observational Study

BACKGROUND

The complementary feeding period is a time of unparalleled dietary change for every human, during which the diet changes from one that is 100% milk to one that resembles the usual diet of the wider family in less than a year. Despite this major dietary shift, we know relatively little about food and nutrient intake in infants worldwide and virtually nothing about the impact of baby food "pouches" and "baby-led weaning" (BLW), which are infant feeding approaches that are becoming increasingly popular. Pouches are squeezable containers with a plastic spout that have great appeal for parents, as evidenced by their extraordinary market share worldwide. BLW is an alternative approach to introducing solids that promotes infant self-feeding of whole foods rather than being fed purées, and is popular and widely advocated on social media. The nutritional and health impacts of these novel methods of infant feeding have not yet been determined.

OBJECTIVE

The aim of the First Foods New Zealand study is to determine the iron status, growth, food and nutrient intakes, breast milk intake, eating and feeding behaviors, dental health, oral motor skills, and choking risk of New Zealand infants in general and those who are using pouches or BLW compared with those who are not.

METHODS

Dietary intake (two 24-hour recalls supplemented with food photographs), iron status (hemoglobin, plasma ferritin, and soluble transferrin receptor), weight status (BMI), food pouch use and extent of BLW (questionnaire), breast milk intake (deuterium oxide "dose-to-mother" technique), eating and feeding behaviors (questionnaires and video recording of an evening meal), dental health (photographs of upper and lower teeth for counting of caries and developmental defects of enamel), oral motor skills (questionnaires), and choking risk (questionnaire) will be assessed in 625 infants aged 7.0 to 9.9 months. Propensity score matching will be used to address bias caused by differences in demographics between groups so that the results more closely represent a potential causal effect.

RESULTS

This observational study has full ethical approval from the Health and Disability Ethics Committees New Zealand (19/STH/151) and was funded in May 2019 by the Health Research Council (HRC) of New Zealand (grant 19/172). Data collection commenced in July 2020, and the first results are expected to be submitted for publication in 2022.

CONCLUSIONS

Education of family members to support weaning to solids and nutrition in later infancy in term-born infants

BACKGROUND

Education of family members about infant weaning practices could affect nutrition, growth, and development of children in different settings across the world.

OBJECTIVES

To compare effects of family nutrition educational interventions for infant weaning with conventional management on growth and neurodevelopment in childhood.

SEARCH METHODS

We used the standard strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 5), MEDLINE via PubMed (1966 to 26 June 2018), Embase (1980 to 26 June 2018), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 26 June 2018). We searched clinical trials databases, conference proceedings, and references of retrieved articles. We ran an updated search from 1 January 2018 to 12 December 2019 in the following databases: CENTRAL via CRS Web, MEDLINE via Ovid, and CINAHL via EBSCOhost.

SELECTION CRITERIA

We included randomised controlled trials that examined effects of nutrition education for weaning practices delivered to families of infants born at term compared to conventional management (standard care in the population) up to one year of age.

DATA COLLECTION AND ANALYSIS

Two review authors independently identified eligible trial reports from the literature search and performed data extraction and quality assessments for each included trial. We synthesised effect estimates using risk ratios (RRs), risk differences (RDs), and mean differences (MDs), with 95% confidence intervals (CIs). We used the GRADE approach to assess the certainty of evidence.

MAIN RESULTS

We included 21 trials, recruiting 14,241 infants. Five of the trials were conducted in high-income countries and the remaining 16 were conducted in middle- and low-income countries. Meta-analysis showed that nutrition education targeted at improving weaning-related feeding practices probably increases both weight-for-age z scores (WAZ) (MD 0.15 standard deviations, 95% CI 0.07 to 0.22; 6 studies; 2551 infants; I² = 32%; moderate-certainty evidence) and height-for-age z scores (0.12 standard deviations, 95% CI 0.05 to 0.19; 7 studies; 3620 infants; I² = 49%; moderate-certainty evidence) by 12 months of age. Meta-analysis of outcomes at 18 months of age was heterogeneous and inconsistent in the magnitude of effects of nutrition education on WAZ and weight-for-height z score across studies. One trial that assessed effects of nutrition education on growth at six years reported an uncertain effect on change in height and body mass index z score. Two studies investigated effects of nutrition education on neurodevelopment at 12 to 24 months of age with conflicting results. No trials assessed effects of nutrition education on long-term neurodevelopmental outcomes.

AUTHORS' CONCLUSIONS

Nutrition education for families of infants may reduce the risk of undernutrition in term-born infants (evidence of low to moderate certainty due to limitations in study design and substantial heterogeneity of included studies). Modest effects on growth during infancy may not be of clinical significance. However, it is unclear whether these small improvements in growth parameters in the first two years of life affect long-term childhood growth and development. Further studies are needed to resolve this question.

Baby-led weaning: prevalence and associated factors in Spain

The main goals of this study are to estimate the percentage of mothers who declared feeding their children with baby-led weaning (BLW) and to characterize them. A cross-sectional survey was carried out in 2016 targeting women who had given birth in 2016 (sample size 6777) in Galicia (Spain). The questionnaire included questions regarding the mother's characteristics and behaviors, attitudes, and practices related to BLW. Prevalence of exclusive and non-exclusive BLW was estimated. Different maternal characteristics were evaluated for their possible association with BLW using a logistic regression model. The percentages and ORs were presented with a 95% confidence interval. The study included 6355 women, of which 38.6% (37.4-39.9) had heard of BLW and the overall prevalence of BLW was estimated at 14.0% (13.1-14.9). Prevalence of exclusive BLW was estimated at 2.1% (2.4-3.3). No differences were observed when age was taken into consideration. Children fed with BLW were more likely among mothers who continue with exclusive breastfeeding (OR, 4.1 (95% CI, 3.3-5.0)); live in an urban setting (OR, 1.6 (1.2-2.2)); or have a higher level of education (OR, 1.3 (1.1-1.5)).Conclusion: Full adherence to BLW seems low among mothers who claimed to have fed their children following this method.What is Known:• Baby-led weaning (BLW) has been present in our society for almost two decades, but it remains unclear how many mothers choose BLW for their children.What is New:• BLW is not a common choice for weaning in Spain, and more than half of the mothers had not heard about it.• Full adherence to BLW seems low among mothers who claimed to have fed their children following this method.

Mediation Analysis as a Means of Identifying Dietary Components That Differentially Affect the Fecal Microbiota of Infants Weaned by Modified Baby-Led and Traditional Approaches

The introduction of "solids" (i.e., complementary foods) to the milk-only diet in early infancy affects the development of the gut microbiota. The aim of this study was to determine whether a "baby-led" approach to complementary feeding that encourages the early introduction of an adult-type diet results in alterations of the gut microbiota composition compared to traditional spoon-feeding. The Baby-Led Introduction to SolidS (BLISS) study randomized 206 infants to BLISS (a modified version of baby-led weaning [BLW], the introduction of solids at 6 months of age, followed by self-feeding of family foods) or control (traditional spoon-feeding of purées) groups. Fecal microbiotas and 3-day weighed-diet records were analyzed for a subset of 74 infants at 7 and 12 months of age. The composition of the microbiota was determined by sequencing of 16S rRNA genes amplified by PCR from bulk DNA extracted from feces. Diet records were used to estimate food and dietary fiber intake. Alpha diversity (number of operational taxonomic units [OTUs]) was significantly lower in BLISS infants at 12 months of age (difference [95% confidence interval {CI}] of 31 OTUs [3.4 to 58.5]; P = 0.028), and while there were no significant differences between control and BLISS infants in relative abundances of Bifidobacteriaceae, Enterobacteriaceae, Veillonellaceae, Bacteroidaceae, Erysipelotrichaceae, Lachnospiraceae, or Ruminococcaceae at 7 or 12 months of age, OTUs representing the genus Roseburia were less prevalent in BLISS microbiotas at 12 months. Mediation models demonstrated that the intake of "fruit and vegetables" and "dietary fiber" explained 29% and 25%, respectively, of the relationship between group (BLISS versus control) and alpha diversity.IMPORTANCE The introduction of solid foods (complementary feeding or weaning) to infants leads to more-complex compositions of microbial communities (microbiota or microbiome) in the gut. In baby-led weaning (BLW), infants are given only finger foods that they can pick up and feed themselves-there is no parental spoon-feeding of puréed baby foods-and infants are encouraged to eat family meals. BLW is a new approach to infant feeding that is increasing in popularity in the United States, New Zealand, the United Kingdom, and Canada. We used mediation modeling, commonly used in health research but not in microbiota studies until now, to identify particular dietary components that affected the development of the infant gut microbiota.

Impact of a Modified Version of Baby-Led Weaning on Infant Food and Nutrient Intakes: The BLISS Randomized Controlled Trial

Despite growing international interest in Baby-Led Weaning (BLW), we know almost nothing about food and nutrient intake in infants following baby-led approaches to infant feeding. The aim of this paper was to determine the impact of modified BLW (i.e., Baby-Led Introduction to SolidS; BLISS) on food and nutrient intake at 7–24 months of age. Two hundred and six women recruited in late pregnancy were randomized to Control (n = 101) or BLISS (n = 105) groups. All participants received standard well-child care. BLISS participants also received lactation consultant support to six months, and educational sessions about BLISS (5.5, 7, and 9 months). Three-day weighed diet records were collected for the infants (7, 12, and 24 months). Compared to the Control group, BLISS infants consumed more sodium (percent difference, 95% CI: 35%, 19% to 54%) and fat (6%, 1% to 11%) at 7 months, and less saturated fat (−7%, −14% to −0.4%) at 12 months. No differences were apparent at 24 months of age but the majority of infants from both groups had excessive intakes of sodium (68% of children) and added sugars (75% of children). Overall, BLISS appears to result in a diet that is as nutritionally adequate as traditional spoon-feeding, and may address some concerns about the nutritional adequacy of unmodified BLW. However, BLISS and Control infants both had high intakes of sodium and added sugars by 24 months that are concerning.

Modifiable "Predictors" of Zinc Status in Toddlers

Suboptimal zinc status is common in very young children and likely associated with increased risk of infection and detrimental effects on growth. No studies have determined potentially modifiable "predictors" of zinc status in toddlers from high-income countries. This cross-sectional analysis of 115 toddlers from the Baby-Led Introduction to SolidS (BLISS) study used weighed diet records (three non-consecutive days) to assess dietary intake, and a venous blood sample (trace-element free techniques) to assess plasma zinc, at 12 months of age. "Predictors" of plasma zinc were determined by univariate analysis and multiple regression. Mean (SD) plasma zinc was 9.7 (1.5) μmol/L, 60% were below the IZiNCG reference limit of <9.9 μmol/L. Median (25th, 75th percentiles) intake of zinc was 4.4 (3.7, 5.4) mg/day. Red meat intake (p = 0.004), consumption of zinc-fortified infant formula (3-6 mg zinc/100 g) (p = 0.026), and food fussiness (p = 0.028) were statistically significant "predictors" of plasma zinc at 12 months. Although higher intakes of red meat, and consumption of infant formula, are potentially achievable, it is important to consider possible barriers, particularly impact on breastfeeding, cost, and the challenges of behavior modification. Of interest is the association with food fussiness-further research should investigate the direction of this association.
