Unpacking the behavioural components and delivery features of early childhood obesity prevention interventions in the TOPCHILD Collaboration: a systematic review and intervention coding protocol.
INTRODUCTION: Little is known about how early (eg, commencing antenatally or in the first 12 months after birth) obesity prevention interventions seek to change behaviour and which components are or are not effective. This study aims to (1) characterise early obesity prevention interventions in terms of target behaviours, delivery features and behaviour change techniques (BCTs), (2) explore similarities and differences in BCTs used to target behaviours and (3) explore effectiveness of intervention components in preventing childhood obesity. METHODS AND ANALYSIS: Annual comprehensive systematic searches will be performed in Epub Ahead of Print/MEDLINE, Embase, Cochrane (CENTRAL), CINAHL, PsycINFO, as well as clinical trial registries. Eligible randomised controlled trials of behavioural interventions to prevent childhood obesity commencing antenatally or in the first year after birth will be invited to join the Transforming Obesity in CHILDren Collaboration. Standard ontologies will be used to code target behaviours, delivery features and BCTs in both published and unpublished intervention materials provided by trialists. Narrative syntheses will be performed to summarise intervention components and compare applied BCTs by types of target behaviours. Exploratory analyses will be undertaken to assess effectiveness of intervention components. ETHICS AND DISSEMINATION: The study has been approved by The University of Sydney Human Research Ethics Committee (project no. 2020/273) and Flinders University Social and Behavioural Research Ethics Committee (project no. HREC CIA2133-1). The study's findings will be disseminated through peer-reviewed publications, conference presentations and targeted communication with key stakeholders.

Transforming Obesity Prevention for CHILDren (TOPCHILD) Collaboration: protocol for a systematic review with individual participant data meta-analysis of behavioural interventions for the prevention of early childhood obesity.
INTRODUCTION: Behavioural interventions in early life appear to show some effect in reducing childhood overweight and obesity. However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials worldwide. Combining the individual participant data (IPD) from these trials will enhance statistical power to determine overall effectiveness and enable examination of individual and trial-level subgroups. We present a protocol for a systematic review with IPD meta-analysis to evaluate the effectiveness of obesity prevention interventions commencing antenatally or in the first year after birth, and to explore whether there are differential effects among key subgroups. METHODS AND ANALYSIS: Systematic searches of Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycInfo and trial registries for all ongoing and completed randomised controlled trials evaluating behavioural interventions for the prevention of early childhood obesity have been completed up to March 2021 and will be updated annually to include additional trials. Eligible trialists will be asked to share their IPD; if unavailable, aggregate data will be used where possible. An IPD meta-analysis and a nested prospective meta-analysis will be performed using methodologies recommended by the Cochrane Collaboration. The primary outcome will be body mass index z-score at age 24±6 months using WHO Growth Standards, and effect differences will be explored among prespecified individual and trial-level subgroups. Secondary outcomes include other child weight-related measures, infant feeding, dietary intake, physical activity, sedentary behaviours, sleep, parenting measures and adverse events. ETHICS AND DISSEMINATION: Approved by The University of Sydney Human Research Ethics Committee (2020/273) and Flinders University Social and Behavioural Research Ethics Committee (HREC CIA2133-1). Results will be relevant to clinicians, child health services, researchers, policy-makers and families, and will be disseminated via publications, presentations and media releases.

However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials worldwide. Combining the individual participant data (IPD) from these trials will enhance statistical power to determine overall effectiveness and enable examination of intervention-covariate interactions. We present a protocol for a systematic review with IPD meta-analysis to evaluate the effectiveness of obesity prevention interventions commencing antenatally or in the first year after birth, and to explore whether there are differential effects among key subgroups
Associations between autism symptom severity and mealtime behaviors in young children presented with an unfamiliar food
BackgroundFeeding problems are common in children with Autism Spectrum Disorder (ASD), and there are associations between parent reports of child ASD symptom severity and feeding problems. The current study further explores this association between ASD severity and family mealtime behaviors using directly observed naturalistic mealtime interactions.Methods and proceduresSeventy-three children (Mage = 5.42 years) were presented an unfamiliar food during a videotaped but otherwise typical home meal. Mealtime behavior was assessed through coding of the videotaped meal using the Dyadic Interaction Nomenclature for Eating (DINE) and parent report (Brief ASD Mealtime Behavior Inventory; BAMBI). ASD severity was assessed with the clinician-completed Childhood Autism Rating Scale-Second Edition (CARS-2).Outcomes and resultsGreater ASD severity was associated with fewer bites of the unfamiliar food, greater disruptive behavior during meals, and greater parental commands to take bites during meals. We found negative associations between limited food variety and food refusal (BAMBI subscales) and child bites of the unfamiliar food, with higher levels of limited food variety and food refusal associated with fewer bites of the unfamiliar food.Conclusions and implicationsChildren with more severe ASD may eat less and be more disruptive during meals, despite parent redirection. We also found associations between the BAMBI and DINE which suggest the BAMBI may be a sensitive measure of mealtime behaviors such as food flexibility and food refusal

Changes in diet quality and home food environment in preschool children following weight management
Abstract Background Family-based obesity treatment interventions can successfully reduce energy intake in preschoolers. An implicit goal of obesity treatment interventions is to improve diet quality, but diet quality has been less examined as a treatment outcome in studies of preschoolers. The purpose of this study was to conduct a secondary analysis comparing the change in diet quality and home food environment in preschoolers assigned to a behavioral family-based obesity intervention (LAUNCH), motivational interviewing (MI) condition, or standard care (STC) condition. Methods Three 24-h dietary recalls were completed at baseline and 6-months and were analyzed using NDS-R software; diet quality was assessed using the Healthy Eating Index-2010 (HEI-2010). Availability of foods and beverages in the home was assessed through direct observation using the Home Health Environment tool that classifies foods and beverages as ‘red’ or ‘green’ based upon fat and sugar content. Repeated measures linear mixed effects models were used to examine changes in diet quality and home food environment between conditions (LAUNCH, MI, STC). Results At 6-months, preschoolers in the LAUNCH condition had a higher HEI-2010 total score (62.8 ± 13.7) compared to preschoolers in the MI (54.7 ± 13.4, P = 0.022) and STC (55.8 ± 11.6, P = 0.046) conditions. Regarding the home food environment, families in LAUNCH had significantly less ‘red’ foods in their home at 6-months (12.5 ± 3.4 ‘red’ foods) compared to families in MI (14.0 ± 3.7 ‘red’ foods, P = 0.030), and STC (14.3 ± 3.4 ‘red’ foods, P = 0.006). There were no statistically significant differences across home food environments for number of ‘green’ foods. Conclusion Family-based obesity treatment interventions for preschoolers can improve overall diet quality and alter the home food environment through reductions in ‘red’ foods.
