Virtual Reality Distraction for Needle-Related Pain and Distress in Children: A Multicenter Randomized Controlled Trial.

This international multicenter randomized controlled trial aimed to compare the effectiveness of virtual reality (VR) distraction with an identical non-VR game in reducing needle-related pain and anxiety in children undergoing venous blood draw. The study involved 304 children aged 5-9 years undergoing a blood draw procedure, randomly allocated to one of three groups: VR distraction, non-VR distraction, and control group (usual care). The distraction task was based on the Multiple Object Tracking (MOT) paradigm, and the game was identical in design and gameplay for both VR and non-VR distraction groups. The primary outcome was self-reported pain intensity using the Faces Pain Scale-Revised (FPS-R). Secondary outcomes included child distress, attention/distraction to the blood draw, and parent and medical staff satisfaction with procedure. Analyses were conducted using analysis of variance and multivariable linear regression models. The results showed that VR distraction and non-VR distraction performed similarly, showing large effect sizes compared with standard care. There was no significant difference between the two types of distraction. The study's findings suggest that VR and non-VR distraction are similarly effective in reducing needle-related pain and anxiety in children undergoing venous blood draw. This is the first well-powered study comparing modern VR distraction with an identical task displayed on a smartphone or monitor screen. The study's results have important implications for using VR in clinical settings and suggest that investing in expensive VR equipment for acute pain management may not be necessary.

Examining the relationship between adversity and suicidality and self-harm in Irish adolescents from 2020 to 2022.

BACKGROUND: Research indicates that there is a strong association between childhood adversity and youth suicide and self-harm. However, there is currently a lack of understanding about the patterns of adversity most frequently experienced by youth across social settings, and whether these typologies differently predict youth engagement in suicide and self-harm. This study examines the dominant patterns of adversity experienced by adolescents across home, peer, and school contexts, and explores the relationship between youth's adversity profiles and their suicide and self-harm outcomes, across a two year period (2020-2022). METHODS: Secondary analyses were performed on data collected from 10,281 (50 % male) adolescents who participated in the Irish Planet Youth questionnaire in 2020 (n = 5004) or 2022 (n = 5277). RESULTS: Findings from clustered latent class analyses indicated that there are four dominant profiles of adversity experienced by adolescents. Class 1 (Multiple Adversity) was characterised by a high probability of experiencing adversity across multiple social settings. Class 2 (Parent Adversity) had a strong likelihood of experiencing adversity with parents. Class 3 (Peer Adversity) were likely to experience adversity within the peer/friend domain. Class 4 was characterised by a low probability of experiencing adversity. Findings from logistic regression models with BCH training weights indicated that there were significant differences in self-harm and suicidality across the adversity classes. In comparison to the low adversity group, adolescents in the multiple adversity group were more likely to self-harm and attempt suicide. LIMITATIONS: These findings are based on cross-sectional data and rely on the use of single-item measurements, which may limit the generalisability of findings. DISCUSSION: Results indicate that youth who experience adversity across home, peer and school contexts are at the greatest risk of engaging in suicide and self-harm. These findings have important implications for policy and practice, and suggest that youth experiencing adversity across multiple settings should be priority targets for intervention.

Participant perspectives on cognitive remediation and social recovery in early psychosis (CReSt-R): An acceptability study.

AIM: Psychosis spectrum disorders continue to rank highly among causes of disability. This has resulted in efforts to expand the range of treatment targets beyond symptom remission to include other recovery markers, including social and occupational function and quality of life. Although the efficacy of psychosocial interventions in early psychosis has been widely reported, the acceptability of these interventions is less well-known. This study explores the participant perspective on a novel, psychosocial intervention combining cognitive remediation and social recovery therapy. METHODS: We employed a qualitative research design, based on semi-structured interviews and reflexive thematic analysis. Six participants with early psychosis were recruited from the intervention arm of a randomized pilot study, three women and three men, aged between 22 and 27 years. RESULTS: Four themes were developed through the analytical process, namely, (1) a solid therapeutic foundation, (2) multi-directional flow of knowledge, (3) a tailored toolset, and (4) an individual pathway to recovery. Participants also provided pragmatic feedback about how to improve the delivery of the therapy assessments and intervention. Both the themes and pragmatic feedback are described. CONCLUSIONS: People with early psychosis described the intervention as acceptable, engaging, helpful and person-centred, suggesting its potential role in a multicomponent therapy model of early intervention in psychosis services. Participants in this study also highlight the importance of an individualized approach to therapy, the vital role of the therapeutic relationship and the ecological validity and value of adopting an assertive outreach delivery, providing therapy outside a conventional clinic setting.

Evaluation of a community-based intervention for youth mental health in rural Ireland.

BACKGROUND: This study aimed to provide information about pathways to care and clinical response to community-based brief interventions for improving youth mental health through evaluating the Mindspace Mayo service. METHODS: Participants were 1,184 individuals aged 12-25 years (Mean = 17.92, SD = 2.66) who engaged with the Mindspace service. Demographic information included gender, age and living situation. The Clinical Outcome in Routine Evaluation (CORE) was used to measure psychological distress before and after attending the Mindspace service between February 2015 and 2022. RESULTS: On average, individuals received six sessions of therapeutic support. Analyses indicated that most referrals were made by either a parent (40%) or self-referral (38%). The most frequent reason for referral was mood and anxiety-related issues. Across the entire sample, reductions in CORE scores were both statistically and clinically significant. Neither the source of the referral nor living situation significantly predicted intervention response. Complexity of issues presented at referral significantly predicted a reduction in psychological distress post-intervention in young people aged over 17 years. CONCLUSIONS: This study highlighted the value of primary care mental health services for young people aged 12-25 years, and underlined the importance of recording electronic data to track referral pathways, reasons for referral and the intervention outcomes over time.

Weight stigma experienced by patients with obesity in healthcare settings: A qualitative evidence synthesis.

Weight stigma research is largely focused on quantifiable outcomes with inadequate representation of the perspectives of those that are affected by it. This study offers a comprehensive systematic review and synthesis of weight stigma experienced in healthcare settings, from the perspective of patients living with obesity. A total of 1340 studies was screened, of which 32 were included in the final synthesis. Thematic synthesis generated three overarching analytical themes: (1) verbal and non-verbal communication of stigma, (2) weight stigma impacts the provision of care, and (3) weight stigma and systemic barriers to healthcare. The first theme relates to the communication of weight stigma perceived by patients within patient-provider interactions. The second theme describes the patients' perceptions of how weight stigma impacts upon care provision. The third theme highlighted the perceived systemic barriers faced by patients when negotiating the healthcare system. Patient suggestions to reduce weight stigma in healthcare settings are also presented. Weight stigma experienced within interpersonal interactions migrates to the provision of care, mediates gaining equitable access to services, and perpetuates a poor systemic infrastructure to support the needs of patients with obesity. A non-collaborative approach to practice and treatment renders patients feeling they have no control over their own healthcare requirements.

Youth Suicide and Self-Harm: Latent Class Profiles of Adversity and the Moderating Roles of Perceived Support and Sense of Safety.

Research suggests that exposure to adversity can lead to an increased risk of experiencing suicidal and self-injurious thoughts or behaviours, but few studies have examined whether different patterns of adversity are differentially associated with youth suicide/self-harm. The current study aims to explore the relationship between exposure to adversity across various social domains and youth self-harm and suicidality, using a person centred approach, and examines whether access to social support and a sense of safety across home, peer or school settings buffer the relationship between adversity and self-harm/suicidality. Secondary data analyses were carried out on cross-sectional self-report data collected from 4848 (Mage=15.78, SD = 0.59; 50% female) adolescents who participated in the Irish Planet Youth survey. Latent Class Analyses identified four distinct profiles of adversity; low-adversity (n = 2043, 42%); peer-adversity (n = 972, 20%); parental-adversity (n = 1189, 25%); and multiple-adversity (n = 644, 13%). Findings from logistic moderated regressions indicated that there were significant differences in self-harm and suicidality across the adversity classes. Although parental support and perceived safety at school were negatively associated with suicidality and self-harm outcomes, no significant moderation effects were observed. These findings suggest that youth who experience adversity across multiple social domains are more likely to report suicidal and self-harm thoughts and behaviours, and should be key targets for intervention/prevention efforts. While parental support and school safety may act as significant compensatory factors, further work is needed to identify the social resources that can offset the risk imposed by youth's adverse experiences.

Obesity in Adults: A 2022 Adapted Clinical Practice Guideline for Ireland.

BACKGROUND: This Clinical Practice Guideline (CPG) for the management of obesity in adults in Ireland, adapted from the Canadian CPG, defines obesity as a complex chronic disease characterised by excess or dysfunctional adiposity that impairs health. The guideline reflects substantial advances in the understanding of the determinants, pathophysiology, assessment, and treatment of obesity. SUMMARY: It shifts the focus of obesity management toward improving patient-centred health outcomes, functional outcomes, and social and economic participation, rather than weight loss alone. It gives recommendations for care that are underpinned by evidence-based principles of chronic disease management; validate patients' lived experiences; move beyond simplistic approaches of "eat less, move more" and address the root drivers of obesity. KEY MESSAGES: People living with obesity face substantial bias and stigma, which contribute to increased morbidity and mortality independent of body weight. Education is needed for all healthcare professionals in Ireland to address the gap in skills, increase knowledge of evidence-based practice, and eliminate bias and stigma in healthcare settings. We call for people living with obesity in Ireland to have access to evidence-informed care, including medical, medical nutrition therapy, physical activity and physical rehabilitation interventions, psychological interventions, pharmacotherapy, and bariatric surgery. This can be best achieved by resourcing and fully implementing the Model of Care for the Management of Adult Overweight and Obesity. To address health inequalities, we also call for the inclusion of obesity in the Structured Chronic Disease Management Programme and for pharmacotherapy reimbursement, to ensure equal access to treatment based on health-need rather than ability to pay.

A Systematic Review of Help-Seeking Interventions for Parents of Adolescents.

PURPOSE: Parents do not always seek timely help for adolescents when the need arises. Although interventions to increase parental help-seeking have been evaluated and published, no systematic review of these interventions has been conducted. The aim of this systematic review is to collate, synthesise, and evaluate research on help-seeking interventions for parents of adolescents. METHODS: Six electronic databases were searched from inception to May 2020 using terms related to the concepts of "parent" and "help-seeking" and focusing on parents of adolescents (aged 10-19 years). Methodological quality was assessed using the Quality Assessment Tool for Quantitative Studies; the Behavioural Change Taxonomy was used to code behavioral change techniques, and "promising interventions" were identified using pre-established criteria. RESULTS: Eighteen studies met inclusion criteria, with six rated strong for design and methodology. The most frequently identified Behavioural Change Taxonomies included a credible source delivering the intervention, supporting parents, and providing prompts/cues regarding services/appointments. Four interventions were identified as "promising" because of strong methodology, significant positive outcomes, and strong evidence-base. CONCLUSIONS: More high-quality, theory-driven parental help-seeking interventions using common outcome measures are needed to advance the literature in this area. Future research should replicate the promising interventions identified to develop best practice guidelines.

Recruiting 'hard to reach' parents for health promotion research: experiences from a qualitative study.

OBJECTIVE: Marginalised populations are less likely to take part in health research, and are sometimes considered 'easy to ignore'. We aimed to describe our approach and results of recruiting parents who experience disadvantage, for focus groups exploring infant feeding on the island of Ireland. Upon receiving ethical approval, we implemented recruitment strategies that included building rapport with community organisations through existing networks, targeting specific organisations with information about our aims, and utilising social media groups for parents. RESULTS: We approached 74 organisations of which 17 helped with recruitment. We recruited 86 parents/carers (one male) for 19 focus groups (15 urban/4 rural). Seventy two percent met at the eligibility criteria. Most participants were recruited through organisations (91%), and the remainder on social media (9%). Recruitment barriers included multiple steps, research fatigue, or uncertainty around expectations. Factors such as building rapport, simplifying the recruitment process and being flexible with procedures were facilitators. Despite comprehensive, multi-pronged approaches, the most marginalised parents may not have been reached. Further alternative recruitment strategies are required for recruiting fathers, rural populations, or those without the capacity or opportunity to engage with local services.

Exploring healthcare professionals' views of the acceptability of delivering interventions to promote healthy infant feeding practices within primary care: a qualitative interview study.

OBJECTIVE: Early-life nutrition plays a key role in establishing healthy lifestyles and preventing chronic disease. This study aimed to (1) explore healthcare professionals' (HCP) opinions on the acceptability of and factors influencing the delivery of interventions to promote healthy infant feeding behaviours within primary care and (2) identify proposed barriers/enablers to delivering such interventions during vaccination visits, to inform the development of a childhood obesity prevention intervention. DESIGN: A qualitative study design was employed using semi-structured telephone interviews. Data were analysed using qualitative content analysis; findings were also mapped to the Theoretical Framework of Acceptability (TFA). SETTING: Primary care in Ireland. PARTICIPANTS: Twenty-one primary care-based HCP: five practice nurses, seven general practitioners, three public health nurses, three community dietitians and three community medical officers. RESULTS: The acceptability of delivering interventions to promote healthy infant feeding within primary care is influenced by the availability of resources, HCP's roles and priorities, and factors relating to communication and relationships between HCP and parents. Proposed barriers and enablers to delivering interventions within vaccination visits include time constraints v. opportunistic access, existing relationships and trust between parents and practice nurses, and potential communication issues. Barriers/enablers mapped to TFA constructs of Affective Attitude, Perceived Effectiveness and Self-Efficacy. CONCLUSIONS: This study provides a valuable insight into HCP perspectives of delivering prevention-focused infant feeding interventions within primary care settings. While promising, factors such as coordination and clarity of HCP roles and resource allocation need to be addressed to ensure acceptability of interventions to HCP involved in delivery.

Psychometric properties of the Peer Mental Health Stigmatization Scale-Revised in adolescents and young adults.

AIM: This study aimed to examine the factorial validity and reliability of the Peer Mental Health Stigmatization Scale (PMHSS) in adolescents and young adults. METHODS: Young people (N = 963) aged 12 to 25 years (M = 16.1, SD = 3.08) were recruited across two studies. Study 1 included adolescents (n = 776) recruited from secondary schools and study 2 included young adults (n = 187) recruited from universities. All participants completed the PMHSS. RESULTS: Exploratory factor analysis resulted in a bi-factorial solution of the PMHSS by retaining 11 items out of the original 16 that loaded on the latent factors of stigma agreement and stigma awareness. Confirmatory factor analysis established the factor structure of the tool in adolescents and young adults. CONCLUSIONS: This shorter version of the PMHSS remains the only validated tool that measures stigma awareness and stigma agreement in youth. We recommend that this version is used in future research.

"They Just Need to Come Down a Little Bit to your Level": A Qualitative Study of Parents' Views and Experiences of Early Life Interventions to Promote Healthy Growth and Associated Behaviours.

The first 1000 days is a critical window of opportunity to promote healthy growth and associated behaviours. Health professionals can play an important role, in part due to the large number of routine contacts they have with parents. There is an absence of research on the views of parents towards obesity prevention and the range of associated behaviours during this time period. This study aimed to elicit parents' views on early life interventions to promote healthy growth/prevent childhood obesity, particularly those delivered by health professionals. Semi-structured interviews were conducted with 29 parents (24 mothers, 5 fathers) who were resident in Ireland and had at least one child aged under 30 months. Data were analysed using reflexive thematic analysis. Two central themes were generated: (1) navigating the uncertainty, stress, worries, and challenges of parenting whilst under scrutiny and (2) accessing support in the broader system. Parents would welcome support during this critical time period; particularly around feeding. Such support, however, needs to be practical, realistic, evidence-based, timely, accessible, multi-level, non-judgemental, and from trusted sources, including both health professionals and peers. Interventions to promote healthy growth and related behaviours need to be developed and implemented in a way that supports parents and their views and circumstances.

A collaborative approach to developing sustainable behaviour change interventions for childhood obesity prevention: Development of the Choosing Healthy Eating for Infant Health (CHErIsH) intervention and implementation strategy.

OBJECTIVES AND DESIGN: There is growing recognition of the need for effective behaviour change interventions to prevent chronic diseases that are feasible and sustainable and can be implemented within routine health care systems. Focusing on implementation from the outset of intervention development, and incorporating multiple stakeholder perspectives to achieve this, is therefore essential. This study explores the development of the Choosing Healthy Eating for Infant Health (CHErIsH) childhood obesity prevention intervention and implementation strategy to improve infant feeding behaviours. METHODS: Five qualitative and quantitative evidence syntheses, two primary qualitative studies, and formal/informal consultations were conducted with practice, policy, research, and parent stakeholders. The Behaviour Change Wheel was used to guide the integration of findings. RESULTS: The CHErIsH intervention targets parent-level behaviour change and comprises (1) brief verbal messages and (2) trustworthy resources, to be delivered by health care professionals (HCPs) during routine infant vaccination visits. The implementation strategy targets HCP-level behaviour change and comprises (1) a local opinion leader, (2) incentivized training, (3) HCP resources and educational materials, (4) electronic delivery prompts, (5) awareness-raising across all primary care HCPs, and (6) local technical support. CONCLUSIONS: This study provides a rigorous example of the development of an evidence-based intervention aimed at improving parental infant feeding behaviours, alongside an evidence-based behaviour change strategy to facilitate implementation and sustainability in primary care. This approach demonstrates how to systematically incorporate multiple stakeholder perspectives with existing literature and move from multiple evidence sources to clearly specified intervention components for both the intervention and implementation strategy. Statement of Contribution What is already known? Incorporating insights from practice, policy, and public/patient stakeholders plays a key role in developing behaviour change interventions that are feasible and sustainable and can be implemented within routine health care systems. However, there are limited examples that provide in-depth guidance of how to do this using a systematic approach. What this study adds? This study describes an innovative use of the Behaviour Change Wheel to integrate multiple sources of evidence collected from practice, policy, research, and parent stakeholders to concurrently develop an evidence-based intervention to improve parental infant feeding behaviours and an implementation strategy to facilitate sustainable delivery by health care professionals in routine primary care.

Peer Support and Role Modelling Predict Physical Activity Change among Adolescents over Twelve Months.

Physical activity levels decline during adolescence; however, some individuals initiate or maintain physical activity participation during this period of life. Socialisation impacts physical activity participation, yet few studies have explored the role of parental and peer processes concurrently on youth physical activity transitions over time. This study examined whether mother's father's and friends' support, modelling and teasing predicted adolescents' physical activity initiation, drop-off or maintenance over twelve months. In total, 803 adolescents (62.5% females, M age = 13.72) from Dublin, Ireland, completed self-report measures of support, modelling, teasing, and physical activity. Participants were classified as physical activity maintainers (17.8%), low active maintainers (58.8%), drop-offs (10.3%) or physical activity initiators (13.1%). The results revealed that parental support and modelling were unrelated to adolescents' physical activity transitions, however mother's and father's support predicted sustained physical activity participation twelve months later. In contrast, peer processes predicted physical activity maintenance, initiation and drop-off at one-year follow-up underscoring the salient role of peers for adolescents' behaviour change. In line with expectancy-value theory, the findings indicate that parents and peers represent distinct socialising agents that impart their influence on adolescents' physical activity maintenance and behaviour change through various mechanisms, highlighting the need to consider both sources of socialisation concurrently in future studies of adolescent behaviour change.

Childhood fussy/picky eating behaviours: a systematic review and synthesis of qualitative studies.

Fussy/picky eating behaviours are common across childhood. Recent reviews of the fussy eating literature focus on quantitative research and do not adequately account for families' subjective experiences, perceptions and practices. This review aims to synthesise the increasing volume of qualitative work on fussy eating. A systematic search of relevant databases was carried out. Studies were included if they were qualitative, published since 2008, with a primary focus on families' experiences, perceptions and practices regarding fussy eating, food neophobia, or food refusal in children (aged one to young adult). Studies with clinical samples, or relating to children under one year were excluded. Ten studies were eligible for this review and were synthesised using meta-ethnography (developed by Noblit and Hare). This review provides a comprehensive description and definition of fussy eating behaviours. A conceptual model of the family experience of fussy eating was developed, illustrating relationships between child characteristics (including fussy eating behaviours), parent feeding beliefs, parent feeding practices, mealtime emotions and parent awareness of food preference development. Our synthesis identified two ways in which fussy eating relates to mealtime emotions (directly and via parent feeding practices) and three distinct categories of parent beliefs that relate to fussy eating (self-efficacy, attributions and beliefs about hunger regulation). The model proposes pathways which could be explored further in future qualitative and quantitative studies, and suggests that parent beliefs, emotions, and awareness should be targeted alongside parent feeding practices to increase effectiveness of interventions. The majority of studies included in this review focus on pre-school children and all report the parent perspective. Further research is required to understand the child's perspective, and experiences of fussy eating in later childhood. PROSPERO Registration: CRD42017055943.

A core outcome set for trials of infant-feeding interventions to prevent childhood obesity.

BACKGROUND: Standardisation of outcomes measured and reported in trials of infant-feeding interventions to prevent childhood obesity is essential to evaluate and synthesise intervention effects. The aim of this study is to develop an infant-feeding core outcome set for use in randomised trials of infant-feeding interventions, with children ≤1 year old, to prevent childhood obesity. METHODS: Core outcome set development followed four stages: (1) systematic review of outcomes reported in the extant literature; (2) meeting with national and international stakeholders to discuss and clarify identified outcomes; (3) e-Delphi study with national and international stakeholders to prioritise outcomes; (4) meeting with national and international stakeholders to reach consensus on outcomes. Stakeholders in stages 2-4 were paediatricians, general practitioners, nurses, midwives, non-clinician researchers, parents, dieticians, nutritionists, and childcare providers. RESULTS: Twenty-six outcomes were identified for inclusion in the core outcome set. These were grouped in nine outcome domains: 'breastfeeding and formula feeding', 'introduction of solids', 'parent feeding practices and styles', 'parent knowledge and beliefs', 'practical feeding', 'food environment', 'dietary intake', 'perceptions of infant behaviour and preferences', and 'child weight'. CONCLUSIONS: The core outcome set identified in this study is the minimum that should be measured and reported in trials of infant-feeding interventions to prevent childhood obesity. This standardisation of outcomes will enable more comprehensive examination and synthesis of the effects of infant-feeding interventions to prevent childhood obesity.

Lending an Ear: iPeer2Peer plus Teens Taking Charge online self-management to empower adolescents with arthritis in Ireland: protocol for a pilot randomised controlled trial.

INTRODUCTION: Juvenile idiopathic arthritis (JIA) negatively affects adolescents' everyday activities. To address the need for innovative, effective, convenient, low-cost psychosocial self-management programmes, we developed an Irish version of Canadian Teens Taking Charge (TTC) and integrated it with Skype-based peer support iPeer2Peer (iP2P). OBJECTIVES: To explore the feasibility and preliminary outcome impact (effectiveness) of an integrated iP2P and Irish TTC, via three-arm (treatment as usual, TTC and iP2P-TTC) pilot randomised controlled trial (RCT); and determine feasibility and sample size for a full RCT. To ensure active involvement of adolescents with JIA via a Young Person Advisory Panel and examine how participants experienced the study. Finally, to see if TTC and iP2P with TTC reduce costs for families. METHODS AND ANALYSIS: Recruitment of 60 families will be ongoing until July 2019, via healthcare professionals and support groups. Analysis will consist of single-blinded (outcome assessment), three-arm pilot RCT, using online questionnaires, with assessments at baseline (T1), after intervention (T2) and 3 months post-intervention (T3). The primary outcomes on feasibility with comparisons of TTC and iP2P-TTC on fidelity, acceptability and satisfaction, engagement and degrees of tailoring. The secondary outcomes will be self-management and self-efficacy and a range of health-related quality-of-life factors, pain indicators and costs.Participants from the intervention groups will be invited to share their perspectives on the process in semistructured interviews. Quantitative data will be analysed using SPSS V.21 and the audio-taped and transcribed qualitative data will be analysed using qualitative content analysis. DISSEMINATION: Via journal articles, conference presentations, co-delivered by key stakeholders when possible, launch of accessible, effective and sustainable Internet self-management and peer support for Irish adolescents with JIA. TRIAL REGISTRATION NUMBER: ISRCTN13535901; Pre-results.

The effectiveness of health professional-delivered interventions during the first 1000 days to prevent overweight/obesity in children: A systematic review.

Childhood obesity is a global public health challenge. Early prevention, particularly during the first 1000 days, is advocated. Health professionals have a role to play in obesity prevention efforts, in part due to the multiple routine contacts they have with parents. We synthesized the evidence for the effectiveness of obesity prevention interventions delivered by health professionals during this time period, as reviews to date have not examined effectiveness by intervention provider. We also explored what behaviour change theories and/or techniques were associated with more effective intervention outcomes. Eleven electronic databases and three trial registers were searched from inception to 04 April 2019. A total of 180 studies, describing 39 trials involving 46 intervention arms, were included. While the number of interventions has grown considerably, we found some evidence for the effectiveness of health professional-delivered interventions during the first 1000 days. Only four interventions were effective on a primary (adiposity/weight) and secondary (behavioural) outcome measure. Twenty-two were effective on a behavioural outcome only. Several methodological limitations were noted, impacting on efforts to establish the active ingredients of interventions. Future work should focus on the conduct and reporting of interventions.

Choosing Healthy Eating for Infant Health (CHErIsH) study: protocol for a feasibility study.

INTRODUCTION: Childhood obesity is a public health challenge. There is evidence for associations between parents' feeding behaviours and childhood obesity risk. Primary care provides a unique opportunity for delivery of infant feeding interventions for childhood obesity prevention. Implementation strategies are needed to support infant feeding intervention delivery. The Choosing Healthy Eating for Infant Health (CHErIsH) intervention is a complex infant feeding intervention delivered at infant vaccination visits, alongside a healthcare professional (HCP)-level implementation strategy to support delivery. METHODS AND ANALYSIS: This protocol provides a description of a non-randomised feasibility study of an infant feeding intervention and implementation strategy, with an embedded process evaluation and economic evaluation. Intervention participants will be parents of infants aged ≤6 weeks at recruitment, attending a participating HCP in a primary care practice. The intervention will be delivered at the infant's 2, 4, 6, 12 and 13 month vaccination visits and involves brief verbal infant feeding messages and additional resources, including a leaflet, magnet, infant bib and sign-posting to an information website. The implementation strategy encompasses a local opinion leader, HCP training delivered prior to intervention delivery, electronic delivery prompts and additional resources, including a training manual, poster and support from the research team. An embedded mixed-methods process evaluation will examine the acceptability and feasibility of the intervention, the implementation strategy and study processes including data collection. Qualitative interviews will explore parent and HCP experiences and perspectives of delivery and receipt of the intervention and implementation strategy. Self-report surveys will examine fidelity of delivery and receipt, and acceptability, suitability and comprehensiveness of the intervention, implementation strategy and study processes. Data from electronic delivery prompts will also be collected to examine implementation of the intervention. A cost-outcome description will be conducted to measure costs of the intervention and the implementation strategy. ETHICS AND DISSEMINATION: This study received approval from the Clinical Research Ethics Committee of the Cork Teaching Hospitals. Study findings will be disseminated via peer-reviewed publications and conference presentations.

Behaviour change techniques and theory use in healthcare professional-delivered infant feeding interventions to prevent childhood obesity: a systematic review.

The conceptual basis of early childhood feeding interventions for obesity prevention is poorly understood. The aim of this systematic review is to characterise these interventions' use of behaviour change techniques (BCTs) and psychological theory, focusing on interventions delivered by healthcare professionals for children ≤ 2 years. We searched seven electronic databases from inception to January 2019 and identified 12 trials. BCTs and theory use were identified using the Behaviour Change Technique Taxonomy v1 and the Theory Coding Scheme respectively. Interventions used 19 BCTs, most commonly 'Instruction on how to perform the behaviour' (12 of 12 studies) and 'Social support (unspecified)' (8 of 12 studies). The mean number of BCTs used was 5.1. Six trials explicitly stated basing interventions on theory, most commonly social cognitive theory and responsive feeding (4 of 6 studies each). Links between theory use and BCTs were poor. Early childhood feeding interventions have insufficiently integrated psychological theories into their development and evaluation. We recommend greater consideration of psychological theory incorporating family and systems approaches and responsive feeding in future intervention development. Moreover, these theories should explicitly link with BCTs. These theories and BCTs should also be included in the evaluation phase.
