Barriers and enablers to Caregivers Responsive feeding Behaviour (CRiB): A mixed method systematic review protocol

Background: Childhood overweight and obesity is a major public health issue. Responsive feeding has been identified as having a protective effect against child overweight and obesity, and is associated with healthy weight gain during infancy. Responsive feeding occurs when the caregiver recognises and responds in a timely and developmentally appropriate manner to infant hunger and satiety cues. Despite its benefits, responsive feeding is not ubiquitous. To better support caregivers to engage in responsive feeding behaviours, it is necessary to first systematically identify the barriers and enablers associated with this behaviour. This mixed-methods systematic review therefore aims to synthesise evidence on barriers and enablers to responsive feeding using the COM-B model of behavioural change. Methods: 7 electronic databases will be searched (Maternal and Infant Care, CINAHL, Cochrane, PubMed, Medline, PsycINFO, EMBASE). Studies examining factors associated with parental responsive and non-responsive feeding of infants and children (<2 years) will be included. Papers collecting primary data, or analysing primary data through secondary analysis will be included. All titles, abstracts and full texts will be screened by two reviewers. Quantitative and qualitative data from all eligible papers will be independently extracted by at least two reviewers using pre-determined standardised data extraction forms. Two reviewers will independently assess the methodological quality of the studies using the Mixed Methods Appraisal Tool (MMAT). This review will be reported according to the Preferred Reporting Items for Systematic reviews and Meta Analyses (PRISMA). Ethics and dissemination: Ethical approval is not required for this review as no primary data will be collected, and no identifying personal information will be present. The review will be disseminated in a peer reviewed journal. PROSPERO registration: CRD42019144570 (06/08/2019)


Amendments from Version 1
Following suggestions from the reviewers, we have amended the introduction to address their comments.Throughout the manuscript, the phrasing was adjusted to avoid individual personal responsibility.In the first paragraph we have included information on the importance of the first 2 years of life in relation to both feeding, and other developmental processes.We have also included a sentence reporting that responsive feeding may be protective, and included a citation to support this.At the end of the second paragraph, we have been more specific the age range of participants in a statement made, and have provided more recent citations to support this.We have also been more specific in regards to parental perception of infant weight, and which feeding styles may correspond.In paragraph 3, we have provided more information about a reference cited, including types of populations and additional information on the factors identified in that review.At the end of this paragraph, we have included that evidence is mixed, and included previous literature mentioning how infant characteristics (such as fussiness, appetitive traits, and genetics) may influence parent feeding.The repetition of the word "supports" (in paragraph 4) was removed and an alternative given.

Introduction
The number of children overweight under the age of five is estimated to be over 41 million 1 , leading to prevalence of overweight and obesity in infants and children being identified as a major public health issue 2 .Infancy is posited to be a sensitive period for the development of child overweight, particularly the first two years 3,4 .The first 2 years are especially important because, during this time, children's feeding preferences and behaviours are influenced by modifiable parental approaches to child feeding that can lead to childhood obesity 5,6 .Throughout this time, infants experience bottle and breastfeeding, complementary feeding 7 , leading onto a solid diet.Beyond this, other critical aspects of child development occur, including development of attachment 8 and self-regulation 9 , and attention 10 which may interact with feeding.For instance, during the first 2 years of life, infants learn to self-regulate their food intake, from their own appetitive traits 11 and from their environment 12 .Childhood obesity can lead to immediate and long term health complications, including, obstructive sleep apnoea, high blood pressure and obesity related cardiovascular disease 13 .Children who have obesity are more likely to have obesity in adulthood, which is associated with a higher risk of many chronic diseases 14 .Parental feeding practices and styles (as outlined in Table 1) are a crucial determinant in the aetiology of childhood obesity 15 , with responsive feeding (both bottle and breast feeding) identified as having a protective effect against child overweight and obesity, and an associated reduced risk of overweight and obesity 16,17 .
Responsiveness is a reciprocal dimension of feeding in which an infant or young child provides clear feeding cues, such as hunger and satiety, and the caregiver responds in a prompt and developmentally appropriate manner 3 .Responsive feeding can relate to early consumption of breast and/or formula milk, as well as in relation to introducing and establishing solid food consumption.From a very young age infants have the ability to selfregulate their food intake 18 but the volume of food an infant consumes depends on their caregiver's ability to recognise and respond appropriately to their infant's hunger and satiety cues, as well as this ability to self-regulate their intake.Non-responsive feeding may occur between an infant and caregiver when a caregiver misinterprets or misunderstands the infant's hunger and satiety cues, and so responds by offering a developmentally inappropriate amount, type or texture of food.Non-responsive feeding may include, instrumental feeding, pressuring a child to eat, and controlling food intake, which have all been associated with childhood overweight and obesity [19][20][21] .Non-responsive feeding can be conceptualised as being at the opposite end of the spectrum to responsive feeding and research suggests it has a role in childhood weight gain and overweight 3 .For example, caregivers who have an inability to recognise an infant's weight is within a healthy range (with the infant being underweight or overweight), often utilise non-responsive feeding styles such as food restriction (for those infants perceived as overweight), or pressuring-to eat

Instrumental feeding
Using food as a reward for a desired outcome (i.e. a positive behaviour).This may strengthen the preference for that food (often high calorie) 19 .

Pressuring to eat
Prompting to eat more food; the caregiver is concerned with increasing the child's food intake (such as adding cereal to a child's bottle to increase intake) 22 .
Monitoring food intake Monitoring a child's food intake; may be expected to result in a lower BMI, however research has often identified no weight change 23 .

Responsive feeding
Responding promptly and in a developmentally appropriate manner to infant cues of satiety and hunger 3 .

Food restriction
Minimising access to food to reduce child's weight.This can result in the opposite effect by causing the child to seek out the restricted food 19 .
(for those infants perceived as underweight) 24,25 .These feeding styles have been associated with children (from birth through to age 18 years inclusive) developing unhealthy eating styles (such as emotional eating and eating in the absence of hunger), leading to an increased risk of obesity [26][27][28] .
Multiple factors may affect how caregivers engage in feeding behaviours.A recent qualitative review included studies consisting of predominantly or only mothers, in Europe, North America, Australasia and Mexico, with the majority of studies recruiting low-income caregivers 29 .This review explored parental experiences of infant feeding and highlighted that some of these influencing factors are environmentally based.).These included costs of infant feeding 30 , time constraints 31 , sources of information (official recommendations 32 , healthcare professionals 33 , and friends and family 30 , confusion of information from multiple sources 34 , and pressure from family 35 .Additional factors include psychological factors (such as maternal mental health 36 and maternal executive functioning 37 ), and social factors (including, interpersonal relationships, marital status, occupation, and the influence of family and friends) 29 .Parental knowledge, beliefs, and prior experience also influence their feeding practices and styles 29 .Previous literature, such as an analysis of the GEMINI cohort study, has noted the importance of genetics in appetitive traits including slowness in eating, satiety responsiveness, food responsiveness and enjoyment of food 11 .Caregivers may also be simply responding to their infant's appetite 12 with infants varying in appetite 38 .Additionally, parents have been found to adjust their feeding style dependent on their child's weight; an infant who is perceived by the parent to be underweight may be pressured to eat more, whilst parents may restrict their infant's food intake if they perceive their infant to be overweight 24 .However, evidence is mixed for maternal pressure to eat, with some research suggesting pressure to eat is associated with increased risk of obesity 3 , meanwhile it has also been reported that pressure to eat is associated with lower weight at 2 years 21 .Infant temperament may also influence feeding practices, with infants perceived as fussier, less responsive to food, and more responsive to internal satiety cues being pressured more 39 .Although the evidence is mixed, it appears that responsive feeding is protective against the development of childhood obesity 40 .
Although sources such as the WHO UNICEF Baby Friendly Initiative (BFI) exist to provide guidance on improving caregivers' knowledge about responsive feeding 41,42 , parents still report uncertainty about how 'best' to feed their infants 29 .It is also suggested that healthcare professionals have not been equipped appropriately to assist caregivers in responsive feeding 43 .In order to improve information and support for caregivers it is necessary to examine the barriers and enablers to responsive feeding.Understanding the underlying factors that influence responsive feeding will contribute to the development of a caregiver-focused support that aids responsive feeding.Systematic reviews have reported that healthcare professionals providing responsive feeding guidance to mothers on identifying and responding to children's satiety and hunger cues can lead to healthy weight status/gain in early childhood 18,[44][45][46][47] .
Of central importance to improving and supporting appropriate responsive feeding behaviours is the fact that some determinants of this behaviour are modifiable, such as caregiver knowledge, and may be specifically targeted through interventions.Models of behaviour change are fundamental to informing such interventions and strategies to promote positive public health 48 .The COM-B (capability, opportunity, motivation and behaviour) model for example provides a framework for understanding behaviour change, and incorporates 'capability', 'opportunity', and 'motivation' are conceptualised as the three conditions necessary for behavioural change 48 .Utilising the COM-B model to map barriers and enablers of responsive feeding behaviours provides a useful and tangible first step towards development of interventions and supports to assist primary caregivers to engage in responsive feeding behaviours that are associated with reduced risk of childhood obesity.

Research questions
What are the barriers and enablers associated to responsive and non-responsive feeding to prevent childhood overweight and obesity?

Study registration
This study has been registered with the international Prospective Register of Systematic Reviews on 6 th August 2019 (PROSPERO; registration number, CRD42019144570).

Study design
A step-by-step flow diagram will be used in accordance with the Preferred Reporting Items for Systematic review and Metaanalysis protocol (PRISMA-P) guidelines, to demonstrate the study selection process, and rationale will be provided for excluded studies.The entirety of the review will follow the PRISMA-P checklist.

Ethics
Ethical approval is not required for this review as no experimental or observational research will be carried out, and no identifying personal information will be present or collected.

Types of studies
This review will examine both qualitative and quantitative primary studies that have examined factors associated with caregiver responsive and nonresponsive feeding of children up to 2 years old.All studies collecting primary data, or analysing primary data through secondary analyse will be included.Quantitative research such as, randomised control trials, case-control studies, retrospective and prospective cohort studies, cross-sectional and longitudinal studies will be included.In addition, qualitative studies, including research conducted as part of the process evaluation of an intervention trial, will be included.A broad remit of studies will be included in order to ensure factors that emerge in a variety of contexts and settings are identified.The studies must be published in English due to limitations in translation resources, and there will be no restriction on publication date.

Inclusion and exclusion criteria Population
Primary caregivers (parents, guardians) of healthy children ≤ 2 years old.Studies of infants with medical conditions affecting feeding and growth, very preterm infants <32 weeks gestation, low birth weight (VLBW) <2500 g 49 , and those who have been fed via a naso-gastric tube will be excluded from this review.We will also exclude studies including infants with major sensory and physical disabilities (e.g.blindness, deafness) because of the additional challenges that caregivers of these infants may find implementing responsive feeding in early life.To ensure the findings can contribute to the development of an intervention to reduce the risk of childhood overweight in a UK and Ireland-relevant population, studies conducted in countries where responsive feeding is used to improve weight gain in malnourished infants will be excluded.Studies will only be included if they are carried out in an economically developed country (as indicated by membership of the Organisation for Economic Co-operation and Development (OECD)) 50 .

Exposures
The exposures of interest are the barriers and enablers associated with primary caregiver feeding responsiveness and nonresponsiveness.Examples of non-responsive feeding include, pressuring a child to eat, instrumental feeding, and controlling food intake which have all been associated with childhood overweight and obesity [19][20][21] .

Outcomes
To be included, studies need to report a factor that could be a barrier or enabler to responsive feeding, for example an intervention that includes anticipatory guidance.Responsive feeding during first 2 years of life as reported by the study authors.This will include outcomes measured using established scales, e.g.Child Feeding Questionnaire 51 , and qualitative data in relation to caregiver feeding practices (such as, ensuring feeding context with few distractions) 52 .Results from quantitative studies (for example, p-values, odds ratios, and confidence intervals) will be used to determine the existence and strength of associations between factors and feeding, whilst results from the qualitative studies (such as themes) will be synthesised to narratively explore barriers and enablers experienced by caregivers to responsive feeding.

Method for identifying studies for inclusion
The following databases will be searched: CINAHL, Cochrane Library, Medline, Embase, PubMed, PsycINFO, Maternity and Infant Care database.All databases will be searched from inception.All databases will be searched using the comprehensive search strategy outlined below.

Search strategy
The searches will be based on concepts associated with infant feeding behaviours to include proxy terms for responsive and non-responsive feeding and any barriers or enablers to primary caregiver engagement.We will use the following search strategy: Feeding type concept: authoritarian OR authoritative OR bottle feeding OR breastfeeding OR breast feeding OR breast-feeding OR complementary feeding OR controlled feeding OR controlling feeding OR emotional feeding OR formula feeding OR non-responsive* OR pressured OR restricted feeding OR restricting feeding OR responsive

Study selection
One researcher (VS) will independently screen titles and abstracts of all identified papers against eligibility criteria.Two other researchers (JR, SR) will each screen titles and abstracts of half of the identified papers.At least two members of the researcher team (VS, JR, KM, EO, SR) will then independently screen full texts of potentially eligible articles for inclusion.Any discrepancies will be resolved by discussion or recourse to a third reviewer from the team (VS, JR, KM, EO, SR).If necessary, the reviewers will attempt to contact authors of original articles to request missing information or for clarification.All references will be imported into EndNote and duplicates will be removed through EndNote and through manual screening.

Data extraction
Raw data from qualitative studies will be extracted onto an Excel spreadsheet and qualitative and quantitative data will be extracted using pre-determined standardised data extraction forms (see extended data 53,54 ).
For the qualitative data extraction one researcher (SR) will extract the study participant, setting and design details of each paper and another researcher (JR) will download any qualitative data from each study to word files.Qualitative data will include the quotes, interpretative text and any other supplementary data.Two researchers (JR, SR) will each examine the qualitative data from three of the included papers and code the data relevant to barriers and enablers to responsive feeding to the COM-B framework.The researchers will meet to compare their interpretation of the data and coding, and any discrepancies will be discussed and resolved.
The quantitative data will be extracted independently by two reviewers (KM, EO), with one researcher (VS) extracting data from all quantitative studies, whilst two more researchers (KM, EO) will each extract data from half of the identified studies.The general study details (including author, title, date) will be extracted along with more specific details such as participant information, infant weight, and intervention details.
Results of the study will be recorded (such as, confidence intervals, p-values, and standard deviations).Identified determinants and association factors identified in quantitative studies will be mapped onto the COM-B model, and will be synthesised with consideration given to the context of the strength of associations and effects.Researchers (VS, KM, EO) will meet to discuss findings of the data extraction and resolve any discrepancies.

Assessment of risk of bias
Two reviewers (VS, SR) will independently assess the methodological quality of these studies using the Mixed Methods Appraisal Tool (MMAT) 55 ; any discrepancies will be resolved through consensus discussion or recourse to a third member of the research team (JR, KM, EO).MMAT provides two screening questionnaires, which are used in the appraisal stage of mixed methods systematic reviews.The MMAT is used to appraise five study types: randomised control trials, non-randomised studies, quantitative studies, qualitative research, and mixed methods design studies.

Strategy for data synthesis
We will use narrative text along with tables of the findings from the included studies, structured around: 1) the relation of barriers and enablers to responsive feeding and non-responsive feeding, and 2) the existence and strength of association between factors and responsive and/or non-responsive feeding outcomes.Depending on the heterogeneity of quantitative studies identified, a meta-analysis will be conducted.
To synthesise the extracted qualitative data, we will use a 'best fit' framework synthesis, as outlined by Booth and Carroll 56 .Framework synthesis is a structured approach in which data are analysed using concepts or themes specified a priori 57,58 .The 'best fit' approach follows seven distinct steps, which includes incorporation of inductively emerging themes with pre-specified themes within the a priori framework.This allows for a flexible and rigorous approach to qualitative evidence synthesis 59 .It provides a pragmatic approach to providing context-specific information and understanding of parents' experiences of, and barriers and facilitators to responsive feeding.The framework to be used is the Capability, Opportunity, and Motivation Model of Behaviour (COM-B model) 48 , and findings will be mapped onto this model.
Participant quotations and authors' interpretations in the results sections of included papers will be coded using the a priori COM-B framework.An inductive thematic analysis of the data will also be conducted and additional themes, which are not accounted for by the COM-B model, will be added to the coding framework.Concepts from the COM-B framework and inductive thematic analysis will then be revisited and synthesised into a final set of themes.
Quantitative data will be extracted onto the COM-B model, with evidence of each barrier and enabler to responsive feeding.All stages of analysis will be conducted by one researcher (VS) and will be reviewed and discussed by all members of the study team to reach consensus on the final evidence synthesis.
Subgroup/subset analysis Subgroup analysis will be determined and led by the data, but may include high/low income, mothers/fathers, primi/multiparous mothers.

Dissemination of findings
The results of this systematic review will be published in a peer-reviewed journal.

Study status
As of the 6 th January 2020, the selected databases have been searched, titles/abstracts have been screened, full texts have been screened against eligibility criteria, and data extraction has started.

Discussion
The aim of this systematic review is to analyse the scientific literature exploring and reporting on barriers and enablers to responsive feeding.The findings will inform researchers, health professionals and caregivers about the ways in which responsive feeding during infancy might be promoted, supported and improved.This could include identification of the groups of caregivers who find responsive feeding more challenging and a clear understanding of the behavioural components which may make this difficult.This should inform the co-production of specific education and support packages for both health professionals and caregivers.
Evidence around the barriers and enablers associated with responsive feeding will also enable researchers to inform health professional communities and to develop and/or adapt any existing interventions.This has the potential to contribute to reduce inappropriate feeding and could be particularly important in the prevention of childhood obesity.It is anticipated that the findings may also inform intervention development in ensuring that barriers to responsive feeding are tackled.In regards to intervention development and improvement, it is important that where it is not possible to modify a particular determinant (for example, maternal executive functioning, or infant temperament) the intervention may be adapted to suit the caregivers specific needs.

Potential limitations
This review will only include studies which are published in English, due to limitations in translation resources.This could mean excluding other relevant information based on language barriers.Secondly, unpublished literature will not be included, possibly leaning towards an increased risk of publication bias in the research that is included.

Amendments
If we need to make any amendments to this protocol, we will give the date of each amendment, describe the change and provide rationale in this section.The protocol is well designed and clearly justified.I have a few comments which I hope will fine tune the manuscript.

Extended data
Please consider adjusting phrasing to ensure 'person first' language and to avoid emphasis on individual personal responsibility: for example, 'Children who are obese are more likely to be obese in adulthood,therefore exposing themselves to a higher risk of many chronic diseases' would be better phrased as 'Children who have obesity are more likely to have obesity in adulthood, which is associated with a higher risk of many chronic diseases'.
A wide range of individual and social factors influencing parental use of responsive feeding are listed in the introduction but core literature is missing, which considers the role of the infant characteristics in responsive feeding.It is likely to be much easier to feed responsively when an infant has appetite within a healthy range, and when an infant gives clear hunger and satiety cues.Studies have shown that infant appetite is strongly related to later BMI and that this is in part genetically mediated (see Gemini cohort outputs).Parents also adjust their feeding in response to changes in weight or appetite across time (e.g.see studies on twins and siblings discordant for appetitive traits).Infants who are more temperamentally difficult may also demonstrate signals that are harder to 'read'.These will also likely constitute important barriers/enablers to responsive feeding.It is of course necessary to focus the review on targets for behaviour change that are potentially modifiable, nonetheless, those parents who are feeding infants who are at the extremes of appetite or temperament traits may also be in greatest need of tailored intervention.
Perhaps these factors can be considered in the proposed subgroup analysis, subject to the data yielded.
Perhaps these factors can be considered in the proposed subgroup analysis, subject to the data yielded.
I was curious why permissive or 'laissez faire' was not included in search terms related to feeding type concept, given that authoritarian and authoritative are included.
I am glad to see the mixed methods approach being taken in this review, this will yield a richer picture of the overall current state of knowledge.The application of the COM-B model to structure of the review will provide an excellent mapping for subsequent intervention planning.

Author Response 03 Jun 2020 , Anglia Ruskin University, Cambridge, UK Vicki Slater Many thanks for taking time to review this protocol manuscript and for your helpful comments.We have spent time addressing these.Firstly, we went through the manuscript and the phrasing was changed in order to ensure 'person first' language to ensure there is no individual personal responsibility.Secondly, we have now included previous literature which includes the role of genetics (as in the Gemini outputs), and additionally the role of infant appetite, and appetitive traits.We have now also included literature on infant fussiness and how this relates to infant feeding.Finally, you mentioned why 'permissive' or 'laissez faire were not included in our search terms.We decided that most often 'laissez faire' and 'permissive' are typically presented/written in combination with the term 'feeding', and as we included 'feeding' within our search terms, papers including 'laissez faire' or 'permissive' would therefore be picked up.Once again, thank you for your comments and taking the time to review our manuscript.

Introduction section:
Research and frameworks (including WHO Commission on Ending Childhood Obesity) would also suggest that the first 2000 days (conception to five years) are critical periods for child development, including establishing eating and weight gain patters.Why might the first two years be particularly important within this time frame?E.g., What specifically happens in a child's life, in relation to eating/weight development, that makes it a critical stage?It seems important to mention that responsive feeding across the first two years will involve periods of breast/bottle feeding, transitioning to solids and for almost all infants, an exclusively solid diet -where the socialisation of children's food preferences and eating behaviours and all manner of child reactions that go with it) are in full swing.Additionally, other critical foundations of child development are being laid during this early period (e.g., child attachment, self-regulation etc…) beyond the feeding scenario that may influence parent feeding/child eating-weight interactions.Hence we really need to consider child development (including weight gain) more holistically.
As per the previous comment: The first sentence in second paragraph of this paper reminds us that feeding is a reciprocal process.Again in the discussion there is a very brief mention of child temperament.Yet the paper seems to focus mainly on the parent and what the parent does during feeding.It would seem appropriate to mention in the introduction some of the characteristics the child might bring to the 'feeding table', which need to be factored in when considering parent feeding.We also know that contributors to child overweight/obesity are more complex and broader than just parent feeding (e.g., genetics, intrauterine effects; social and health inequities, particularly now that we have evidence showing rates of under and over nutrition often go hand in hand in low to middle-income populations), and this should be acknowledged, even if beyond the scope of the proposed review.

"
…": It would be helpful to clarify for Inability to recognize an infant's weight is within a healthy weight range the reader if this is in regards to infants being over or under weight or both and what parental feeding was observed according to types of weight perceptions.E.g., what did mothers do if they perceived their child to be underweight and then overweight?: Please "These feeding styles have been associated with children developing unhealthy eating styles" confirm for the reader if this is referring to infants or children in older age groups and provide citations for specific studies supporting the statement.Please use more recent citations if possible given that reference of review cited is from 2007.It also seems necessary to make it clear that evidence relating to child feeding and outcomes has been mixed (and there are reasons for this), but largely, it appears that child feeding and outcomes has been mixed (and there are reasons for this), but largely, it appears that responsive feeding may be protective....
