The feeding siblings questionnaire (FSQ): Development of a self-report tool for parents with children aged 2-5 years.

Over the last decade, there have been repeated calls to expand the operationalisation of food parenting practices. The conceptualisation and measurement of these practices has been based primarily on research with parent-child dyads. One unexplored dimension of food parenting pertains to the evaluation of practices specific to feeding siblings. This study describes the development and validation of the Feeding Siblings Questionnaire (FSQ) - a tool designed to measure practices in which siblings are positioned as mediators in parents' attempts to prompt or persuade a child to eat. Item development was guided by a conceptual model derived from mixed-methods research and refined through expert reviews and cognitive interviews. These interviews were conducted in two phases, where parents responded to the questionnaire primarily to test i) the readability and relevance of each item, and ii) its overall feasibility. The instrument was completed by 330 parents (96.1% mothers) in Australia with two children aged 2-5 years, and repeated by 133 parents (40.3%) two weeks later. Exploratory factor analysis was performed on baseline data. Internal consistency and test re-test reliability of the subsequent subscales were examined. Construct validity was assessed through comparisons with existing measures of food parenting practices and child eating behaviours. The final FSQ scale included 22 items, reflecting five food parenting practices: sibling competitiveness, active sibling influence, threatening unequal division of food, sibling role modelling, and vicarious operant conditioning. Internal consistency and test re-test reliability estimates were high, and there was some evidence of convergent construct validity. While its factor structure should be confirmed in a different sample, the FSQ offers a novel tool for assessing, monitoring, and evaluating feeding interactions beyond those confined to the parent-child dyad.

Reliability and validity of rapid assessment tools for measuring 24-hour movement behaviours in children aged 0-5 years: the Movement Behaviour Questionnaire Baby (MBQ-B) and child (MBQ-C).

BACKGROUND: The development of validated "fit-for-purpose" rapid assessment tools to measure 24-hour movement behaviours in children aged 0-5 years is a research priority. This study evaluated the test-retest reliability and concurrent validity of the open-ended and closed-ended versions of the Movement Behaviour Questionnaire for baby (MBQ-B) and child (MBQ-C). METHODS: 300 parent-child dyads completed the 10-day study protocol (MBQ-B: N = 85; MBQ-C: N = 215). To assess validity, children wore an accelerometer on the non-dominant wrist (ActiGraph GT3X+) for 7 days and parents completed 2 × 24-hour time use diaries (TUDs) recording screen time and sleep on two separate days. For babies (i.e., not yet walking), parents completed 2 × 24-hour TUDs recording tummy time, active play, restrained time, screen time, and sleep on days 2 and 5 of the 7-day monitoring period. To assess test-retest reliability, parents were randomised to complete either the open- or closed-ended versions of the MBQ on day 7 and on day 10. Test-retest intraclass correlation coefficients (ICC's) were calculated using generalized linear mixed models and validity was assessed via Spearman correlations. RESULTS: Test-retest reliability for the MBQ-B was good to excellent with ICC's ranging from 0.80 to 0.94 and 0.71-0.93 for the open- and closed-ended versions, respectively. For both versions, significant positive correlations were observed between 24-hour diary and MBQ-B reported tummy time, active play, restrained time, screen time, and sleep (rho = 0.39-0.87). Test-retest reliability for the MBQ-C was moderate to excellent with ICC's ranging from 0.68 to 0.98 and 0.44-0.97 for the open- and closed-ended versions, respectively. For both the open- and closed-ended versions, significant positive correlations were observed between 24-hour diary and MBQ-C reported screen time and sleep (rho = 0.44-0.86); and between MBQ-C reported and device-measured time in total activity and energetic play (rho = 0.27-0.42). CONCLUSIONS: The MBQ-B and MBQ-C are valid and reliable rapid assessment tools for assessing 24-hour movement behaviours in infants, toddlers, and pre-schoolers. Both the open- and closed-ended versions of the MBQ are suitable for research conducted for policy and practice purposes, including the evaluation of scaled-up early obesity prevention programs.

A design thinking-led approach to develop a responsive feeding intervention for Australian families vulnerable to food insecurity: Eat, Learn, Grow.

BACKGROUND: Design thinking is an iterative process that innovates solutions through a person-centric approach and is increasingly used across health contexts. The person-centric approach lends itself to working with groups with complex needs. One such group is families experiencing economic hardship, who are vulnerable to food insecurity and face challenges with child feeding. OBJECTIVE: This study describes the application of a design thinking framework, utilizing mixed methods, including co-design, to develop a responsive child-feeding intervention for Australian families-'Eat, Learn, Grow'. METHODS: Guided by the five stages of design thinking, which comprises empathizing, defining, ideating, prototyping, and testing. We engaged with parents/caregivers of a child aged 6 months to 3 years through co-design workshops (n = 13), direct observation of mealtimes (n = 10), a cross-sectional survey (n = 213) and semistructured interviews (n = 29). Findings across these methods were synthesized using affinity mapping to clarify the intervention parameters. Parent user testing (n = 12) was conducted online with intervention prototypes to determine acceptability and accessibility. A co-design workshop with child health experts (n = 9) was then undertaken to review and co-design content for the final intervention. RESULTS: Through the design thinking process, an innovative digital child-feeding intervention was created. This intervention utilized a mobile-first design and consisted of a series of short and interactive modules that used a learning technology tool. The design is based on the concept of microlearning and responds to participants' preferences for visual, brief and plain language information accessed via a mobile phone. User testing sessions with parents and the expert co-design workshop indicated that the intervention was highly acceptable. CONCLUSIONS: Design thinking encourages researchers to approach problems creatively and to design health interventions that align with participant needs. Applying mixed methods-including co-design- within this framework allows for a better understanding of user contexts, preferences and priorities, ensuring solutions are more acceptable and likely to be engaged.

Food Insecurity and Feeding Experiences Among Parents of Young Children in Australia: An Exploratory Qualitative Study.

BACKGROUND: Responsive feeding is a reciprocal process between caregiver and child that is primarily child-led. It is linked to the development of positive eating behaviors and food preferences. There is evidence that household chaos, family dynamics, the quality of mealtime routines, financial hardship, and food insecurity can impact the feeding relationship. OBJECTIVE: This study explored factors influencing feeding experiences among Australian parents with young children experiencing financial hardship, including household chaos and food insecurity. DESIGN: This qualitative semi-structured interview study was conducted as a component of a larger research program to design and evaluate a parent program to support responsive feeding practices in Australian families experiencing financial hardship and food insecurity. PARTICIPANTS/SETTING: Participants were caregivers of a child aged 6 months to 3 years (n = 29), living in Australia, who self-identified as experiencing financial hardship. Interviews were conducted in person and via telephone between August 2021 and January 2022. ANALYSIS: Transcripts were analyzed using the Framework Method of thematic analysis. RESULTS: Five key themes were generated: family tensions heightened through hardship, making tradeoffs and sacrifices, the unseen mental load, the inescapable impact of COVID-19, and resiliency and being creative. Despite facing multiple hardships and challenges with feeding the family, parents demonstrated resilience and capabilities through creative food resource management and organizational skills. Parents experienced a high mental load through the cognitive and emotional work of planning, adapting, anticipating, and caring for the family's needs through meals and child feeding. CONCLUSIONS: Programs to support child feeding need to consider the high mental load families with food insecurity experience and how this can impact parents' capacity. Program content should be contextually sensitive to the experience of food insecurity and consider the constraints inherent in families and communities while building on capabilities and strengths.

A great way to bring up health behaviour topics at playgroup: a qualitative evaluation of the Healthy Conversations @ Playgroup program.

BACKGROUND: The early years is a critical stage to establish optimal nutrition and movement behaviours. Community playgroups are a relaxed environment for parents with a focus on social connection and supporting parents in their role as 'First Teachers'. Playgroups are therefore an opportunistic setting to promote health behaviours in the early years. To support parents with young children around healthy lifestyle behaviours, the Healthy Conversations @ Playgroup program was delivered in urban and regional areas, across three Australian jurisdictions between 2021-2023. OBJECTIVE: This qualitative evaluation aimed to understand how the Healthy Conversations @ Playgroup program was experienced by parents, playgroup coordinators and peer facilitators. DESIGN: Semi-structured virtual interviews and focus groups were conducted with parents, playgroup coordinators (i.e., person responsible for coordinating the playgroup) and peer facilitators (i.e., trained facilitator for the program) that participated in the Healthy Conversations @ Playgroup study. Transcripts were analysed following a thematic analysis approach. RESULTS: Twenty-eight playgroup parents, coordinators or peer facilitators participated in one of 8 focus groups or 5 interviews. Four themes were developed: Program strengths and challenges; Setting strengths and challenges; Factors that impact program delivery; Participant's suggestions for future program delivery. CONCLUSIONS: The Healthy Conversations @ Playgroup program was valued by parents, providing validation and normalisation of parenting practices, and fostering a shared experience of parenting. Playgroups are a convenient setting for families to attend. The dynamic and distracting nature of the playgroup setting were carefully considered when designing the program. Strategies to further enhance program engagement could include use of coordinator or parent champions, tailored delivery, and extending the reach to other family members.

Development and validation of a short dietary questionnaire for assessing obesity-related dietary behaviours in young children.

There are few short, validated tools to assess young children's obesity-related dietary behaviours, limiting the rapid screening of dietary behaviours in research and practice-based early obesity prevention. This study aimed to develop and assess the reliability and validity of a caregiver-reported short dietary questionnaire to rapidly assess obesity-related dietary behaviours in children aged 6 months to 5 years. The Early Prevention of Obesity in Childhood Dietary Questionnaire (EPOCH-DQ) was developed using a rigorous process to determine content and structural validity. Three age-appropriate versions were developed for (1) infants, aged 6-12 months, (2) toddlers, aged 1-2.9 years and (3) pre-schoolers, aged 3-5 years. The questionnaire (7-15 items) measures dietary behaviours, including diet risk from non-core food and beverage intake, diet quality from vegetable frequency, bread type and infant feeding practices. Test-retest reliability was assessed from repeated administrations 1 week apart (n = 126). Internal consistency, concurrent validity (against a comparison questionnaire, the InFANT Food Frequency Questionnaire), construct validity and interpretability were assessed (n = 209). Most scores were highly correlated and significantly associated (p < 0.05) for validity (rs: 0.45-0.89, percentage agreement 68%-100%) and reliability (intraclass correlation coefficient: 0.61-0.99) for diet risk, diet quality and feeding practice items. The EPOCH-DQ shows acceptable validity and reliability for screening of obesity-related behaviours of children under 5 years of age. The short length and, thus, low participant burden of the EPOCH-DQ allows for potential applications in various settings. Future testing of the EPOCH-DQ should evaluate culturally and socio-economically diverse populations and establish the predictive validity and sensitivity to detect change.

Screening tools used in primary health care settings to identify health behaviours in children (birth-16 years); A systematic review of their effectiveness, feasibility and acceptability.

BACKGROUND: Child health behaviour screening tools have potential to enhance the effectiveness of health promotion and early intervention. This systematic review aimed to examine the effectiveness, acceptability and feasibility of child health behaviour screening tools used in primary health care settings. METHODS: A systematic review of studies published in English in five databases (CINAHL, Medline, Scopus, PsycINFO and Web of Science) prior to July 2022 was undertaken. Eligible studies described: 1) screening tools for health behaviours (dietary, physical activity, sedentary or sleep-related behaviours) used in primary health care settings in children birth to 16 years; 2) tool effectiveness for identifying child health behaviours and changing practitioner behaviour; 3) tool acceptability or feasibility from child, caregiver or practitioner perspective and/or 4) implementation of the screening tool. RESULTS: Of the 7145 papers identified, 22 studies describing 14 screening tools were included. Only four screening tools measured all four behaviour domains. Fourteen studies reported changes in practitioner self-reported behaviour, knowledge and practice. Practitioners and caregivers identified numerous benefits and challenges to screening. CONCLUSIONS: Health behaviour screening can be an acceptable and feasible strategy to assess children's health behaviours in primary health care. Further evaluation is needed to determine effectiveness on child health outcomes.

"You just have to spread it thin": Perceptions and feeding experiences of Australian fathers of young children living with disadvantage.

The role of fathers in feeding is an emerging field within child feeding literature. Fathers have unique contributions to make to family mealtimes and child eating behaviours. However, qualitative research on fathers' experiences is limited, especially in the context of disadvantage. This study explored fathers' perceptions of their roles and feeding practices and their lived experience of disadvantage through a symbolic interactionism lens. Twenty-five Australian fathers of children aged six months to five years who experienced socioeconomic disadvantage participated in semi-structured interviews. Five themes were constructed from reflexive thematic analysis: (i) responsibilities for foodwork are based on strengths, opportunities, and values, (ii) negotiating fatherhood identity from a place of tension to acceptance, (iii) struggling with financial and mental strain, and food insecurity, (iv) managing adversity whist prioritising feeding children, and (v) paternal feeding practices are driven by values, adversity, and emotions. The division of foodwork was contingent on family capability and employment, maternal gatekeeping, paternal attitudes and values, and intergenerational, cultural and gender norms around earning and childrearing. Economic, environmental, and emotional stressors triggered changes to fathers' feeding practices, often contradicting their ideals (e.g., providing alternative meals, using rewards and electronic devices, unstructured settings). Fathers described income and food-based strategies to protect children's food intake, which may involve caregivers forgoing meals. These findings provide insight into fathers' feeding experiences through recognising personal, interpersonal, and systemic enablers and barriers. Promoting optimal feeding practices should include targeted feeding support and broader structural interventions to address inequality. Fathers' experiences as they navigate child mealtime interactions within a context of adversity can be used to inform child feeding interventions to improve child health and development.

A Double-Blind Randomised Controlled Trial of Prebiotic Supplementation in Children with Autism: Effects on Parental Quality of Life, Child Behaviour, Gastrointestinal Symptoms, and the Microbiome.

PURPOSE: Modifying gut bacteria in children with autism may influence behaviour, with potential to improve family functioning. We conducted a randomised controlled trial to assess the effect of prebiotics on behaviour, gastrointestinal symptoms and downstream effects on parental quality of life. METHOD: Children with autism (4-10yrs) were randomised to 2.4 g/d of prebiotic (GOS) or placebo for six weeks. Pre and post stools samples were collected, and validated questionnaires used to measure change in social and mealtime behaviours, GI symptoms and pQOL. Linear mixed models evaluated group differences for behavioural variables, and Mann Whitney U tests were used to compare change between-groups for GI symptoms, differential abundance of genera and alpha diversity of the microbiome. RESULTS: Thirty-three parent-child dyads completed the trial. No group difference was seen for behavioural variables but both groups improved significantly from baseline. There was a medium effect size between groups for GI symptoms (d = 0.47) and pQOL (d = 0.44) driven by greater improvements in the prebiotic group. Bifidobacterium increased threefold following prebiotics (1.4-5.9%, p < 0.001) with no change in controls. Supplements were well tolerated, compliance with dose 94%. CONCLUSION: Prebiotics modify levels of Bifidobacterium and prove well tolerated but in this instance, resulted in only marginal effects on GI symptoms and pQOL. A larger sample of children with more severe symptoms could help to determine the potential of prebiotics in autism.

Dads at Mealtimes: Associations between Food Security, Household and Work Chaos, and Paternal Feeding Practices among Australian Fathers Living with Disadvantage.

Understanding how fathers engage in feeding while experiencing disadvantage is important for family-focused interventions. A cross-sectional online survey involving 264 Australian fathers was conducted to explore feeding involvement and the relationships between feeding practices, food insecurity, and household and work chaos. Practices related to coercive control, structure, and autonomy support were measured for two age groups (<2 years and 2-5 years). Multivariable linear regression was used to examine the associations for each practice. Three-quarters of the sample were food insecure, impacting adults more than children, and correlated with household chaos. Food insecurity was associated with increased 'persuasive feeding' and 'parent-led feeding' in younger children. Household chaos was positively associated with coercive control practices in both younger and older child groups, with the strongest associations for 'using food to calm' and 'overt restriction', respectively. In older child groups, household chaos was negatively associated with 'offer new foods' and 'repeated presentation of new foods'. Structure practices had no significant relationships with any factors, and work chaos did not predict any feeding practices. These findings emphasize a need for societal and structural support to address food insecurity and household chaos. Tailored strategies are crucial to support fathers in responsive feeding.

Barriers and enablers to a healthy food environment in Australian childcare services: Exploring directors' perspectives.

ISSUE ADDRESSED: Early childhood education and care (ECEC) settings are ideal environments to optimise nutrition and positively influence children's food behaviours. However, recent research has identified the need to improve nutrition policies, food provision, and mealtime environments in Australian ECEC settings. This study explored the perceptions of ECEC directors regarding barriers and enablers to a health-promoting food environment within ECEC services. METHODS: Eleven directors from ECEC services in Nerang, Queensland, and surrounding areas, participated in qualitative interviews between March and May 2021. Transcripts were analysed using qualitative content analysis that followed a deductive-inductive approach employing nutrition-related domains from the Wellness Child Care Assessment Tool, these being: (i) nutrition policy; (ii) nutrition education; (iii) food provision; and (iv) mealtimes. Transcripts were coded independently by two researchers in NVivo and consensus for barriers and enablers was achieved through discussion. RESULTS: Barriers and enablers were reported across four domains (nutrition policy, nutrition education, food provision, and mealtimes). Comprehensive nutrition-related policies were an enabler to a healthy nutrition environment but were sometimes described as lacking detail or customisation to the service. Nutrition education for children was described as competing with other activities for time and resources in an already-crowded curriculum. Financial and time pressures faced by families were a barrier to healthy food provision in services where families provided food for children. The ability of staff to sit with children and engage in conversation during mealtimes was an enabler; however, competing demands on time and the unavailability of food for staff were cited as barriers to health-promoting mealtimes. CONCLUSIONS: Directors in ECEC services report both barriers and enablers to a healthy food environment. Nutrition policies were an enabler when comprehensive and relevant but a barrier when vague and not tailored to the service environment. ECEC services should be supported to develop and implement service-specific nutrition policies and practices by engaging with parents and staff. SO WHAT?: The barriers and enablers reported in this study should be considered when designing and implementing future evidence-based interventions to improve the nutrition environment in ECEC services.

Food Parenting Practices and Child Eating Behaviors in Australian Families: A Cross-Sectional Sibling Design.

BACKGROUND: Research on feeding in early childhood has focused primarily on parent-child dyadic interactions, despite parents enacting these practices within the complex dynamic of the family system. OBJECTIVE: Using a sibling design, this study aimed to assess how parents may adapt their food parenting practices for siblings in response to differences in their eating behaviors. DESIGN: A cross-sectional online survey was conducted between October and December 2022. PARTICIPANTS/SETTING: Data were collected from parents (97.5% women) in Australia with 2 children aged 2 to 5 years (n = 336 parents and n = 672 children). MAIN OUTCOME MEASURES: Survey items were completed for each sibling, and included four subscales of the Children's Eating Behaviour Questionnaire and seven subscales of the Feeding Practices and Structure Questionnaire-28. STATISTICAL ANALYSES PERFORMED: Multiple linear regression models examined associations between within-sibling pair differences in child eating behaviors and food parenting practices, adjusting for differences in child body mass index z score, age, gender, and early feeding method. RESULTS: Within-sibling pair differences in eating behaviors were associated with differences in some food parenting practices. For the fussier sibling, parents reported using more control-based practices, including persuasive feeding, reward for eating, and reward for behavior, and less of the structure-based practice, family meal settings (P values < 0.001). Similar directions of associations were found for persuasive feeding, reward for eating, and family meal settings with siblings who were slower eaters or more satiety responsive (P values < 0.007); however, no significant differences in reward for behavior were observed in relation to sibling differences in these eating behaviors. For the more food responsive sibling, parents reported using more control-based practices, including reward for behavior and overt restriction (P values < 0.002). CONCLUSIONS: Within families, parents may adapt certain practices in response to differences in their children's eating behaviors. Interventions promoting responsive feeding should be designed to acknowledge the integral role of siblings in shaping parents' feeding decisions.

Female Leadership during COVID-19: The Effectiveness of Diverse Approaches towards Mitigation Management during a Pandemic.

This paper tackles the question of how female leaders at national levels of government managed COVID-19 response and recovery from the first COVID-19 case in their respective countries through to 30 September 2021. The aim of this study was to determine which COVID-19 mitigations were effective in lowering the viral reproduction rate and number of new cases (per million) in each of the fourteen female presidents' countries-Bangladesh, Barbados, Belgium, Bolivia, Denmark, Estonia, Finland, Germany, Iceland, Lithuania, New Zealand, Norway, Serbia, and Taiwan. We first compared these countries by finding a mean case rate (29,420 per million), mean death rate (294 per million), and mean excess mortality rate (+1640 per million). We then analyzed the following mitigation measures per country: school closing, workplace closing, canceling public events, restrictions on gatherings, closing public transport, stay-at-home requirements, restrictions on internal movement, international travel controls, income support, debt/contract relief, fiscal measures, international support, public information campaigns, testing policy, contact tracing, emergency investment in healthcare, investment in vaccines, facial coverings, vaccination policy, and protection of the elderly. We utilized the random forest approach to examine the predictive significance of these variables, providing more interpretability. Subsequently, we then applied the Wilcoxon rank-sum statistical test to see the differences with and without mitigation in effect for the variables that were found to be significant by the random forest model. We observed that different mitigation strategies varied in their effectiveness. Notably, restrictions on internal movement and the closure of public transportation proved to be highly effective in reducing the spread of COVID-19. Embracing qualities such as community-based, empathetic, and personable leadership can foster greater trust among citizens, ensuring continued adherence to governmental policies like mask mandates and stay-at-home orders, ultimately enhancing long-term crisis management.

Cognitive Testing of Items Measuring Movement Behaviours in Young Children Aged Zero to Five Years: Development of the Movement Behaviour Questionnaires for -Baby (MBQ-B) and -Child (MBQ-C).

This paper describes the cognitive interview phase of the development of two brief surveys, the Movement Behaviour Questionnaire-Baby (MBQ-B) and Movement Behaviour Questionnaire-Child (MBQ-C), which measure the duration of physical activity, screen time, and sleep of children aged 0-5 years. The aims were (1) review the format, content, and clarity of questionnaire items and response options, (2) understand how parents retrieve, encode, and formulate responses when asked about their child's movement behaviours, and (3) identify potential sources of response error and make appropriate modifications. Interviews with parents of children aged 0-5 years were conducted using concurrent think-aloud techniques and probing questions. Parents reviewed the MBQ-B and/or MBQ-C depending on the developmental stage of their child(ren). Twenty-nine interviews were conducted with 20 parents, over four iterative rounds. Participants recalled usual family routines and rules when estimating the duration/frequency of behaviours. To estimate active play, parents referred to the child's daily routine considering wake and bedtimes, naps, and mealtimes. Participants were influenced by the examples provided, being unable to interpret these as exemplars only. Decomposing general items into specific questions with examples was well received. Use of numeracy skills when estimating duration was evident. Interviews informed revisions to item wording, examples, and recall prompts, which will be taken forward into the MBQ-B and MBQ-C validation studies. Utilising cognitive interviewing can enhance confidence that questionnaire items are correctly interpreted and understood by participants.

Understanding the pathways between prenatal and postnatal factors and overweight outcomes in early childhood: a pooled analysis of seven cohorts.

BACKGROUND/OBJECTIVES: Childhood overweight and obesity are influenced by a range of prenatal and postnatal factors. Few studies have explored the integrative pathways linking these factors and childhood overweight. This study aimed to elucidate the integrative pathways through which maternal pre-pregnancy body mass index (BMI), infant birth weight, breastfeeding duration, and rapid weight gain (RWG) during infancy are associated with overweight outcomes in early childhood from ages 3 to 5 years. SUBJECTS/METHODS: Pooled data from seven Australian and New Zealand cohorts were used (n = 3572). Generalized structural equation modelling was used to examine direct and indirect associations of maternal pre-pregnancy BMI, infant birth weight, breastfeeding duration, and RWG during infancy with child overweight outcomes (BMI z-score and overweight status). RESULTS: Maternal pre-pregnancy BMI was directly associated with infant birth weight (ß 0.01, 95%CI 0.01, 0.02), breastfeeding duration ≥6 months (OR 0.92, 95%CI 0.90, 0.93), child BMI z-score (ß 0.03, 95%CI 0.03, 0.04) and overweight status (OR 1.07, 95%CI 1.06, 1.09) at ages 3-5 years. The association between maternal pre-pregnancy BMI and child overweight outcomes was partially mediated by infant birth weight, but not RWG. RWG in infancy exhibited the strongest direct association with child overweight outcomes (BMI z-score: ß 0.72, 95%CI 0.65, 0.79; overweight status: OR 4.49, 95%CI 3.61, 5.59). Infant birth weight was implicated in the indirect pathways of maternal pre-pregnancy BMI with RWG in infancy, breastfeeding duration, and child overweight outcomes. The associations between breastfeeding duration (≥6 months) and lower child overweight outcomes were fully mediated by RWG in infancy. CONCLUSIONS: Maternal pre-pregnancy BMI, infant birth weight, breastfeeding duration and RWG in infancy act in concert to influence early childhood overweight. Future overweight prevention interventions should target RWG in infancy, which showed the strongest association with childhood overweight; and maternal pre-pregnancy BMI, which was implicated in several pathways leading to childhood overweight.

'I'm having jelly because you've been bad!': A grounded theory study of mealtimes with siblings in Australian families.

Obesity prevention interventions have been designed to promote responsive feeding in early childhood. However, existing interventions primarily target first-time mothers without considering the complexities of feeding multiple children within a family unit. By applying principles of Constructivist Grounded Theory (CGT), this study aimed to explore how mealtimes are enacted in families with more than one child. A mixed-methods study was conducted with parent-sibling triads (n = 18 families) in South East Queensland, Australia. Data included direct mealtime observations, semistructured interviews, field notes, and memos. Data were analysed using open and focused coding, during which constant comparative analysis was applied. The sample comprised of two-parent families with children ranging in age from 12 to 70 months (median sibling age difference = 24 months). A conceptual model was developed to map sibling-related processes integral to the enactment of mealtimes in families. Notably, this model captured feeding practices used by siblings, such as pressure to eat and overt restriction, that previously had only been described in parents. It also documented feeding practices used by parents that may occur only in the presence of a sibling, such as leveraging sibling competitiveness and rewarding a child to vicariously condition their sibling's behaviour. The conceptual model demonstrates complexities in feeding that give shape to the overall family food environment. Findings from this study can inform the design of early feeding interventions that support parents to remain responsive, particularly when their perceptions and expectations of siblings differ.

Parental Influences on Physical Activity and Screen Time among Preschool Children from Low-Income Families in Brazil.

Background: Children from low-middle income countries (LMIC) are disproportionately affected by obesity, and low physical activity (PA) and high screen time (ST) are major contributors. Parents are key influencers on children's PA and ST, yet, no study has investigated relationships between parenting practices and children's PA and ST in LMIC families. This study examined parental influences on PA and ST among preschool-aged children from low-income families in Brazil. Methods: Parents completed a validated, culturally adapted interviewer-administered survey assessing child ST and parenting practices. Child sedentary time, total movement, and energetic play were measured by accelerometery. Results: Data were available on 77 parent-child dyads [mean age 4.6 years (standard deviation = 0.8), 53% male, and 41% mixed-race]. Parenting practices associated with greater PA were use of PA to reward/control behavior (rho = 0.34-0.49), limiting or monitoring ST (rho = 0.30), explicit modeling/enjoyment of PA (rho = 0.24), verbal encouragement for PA (rho = 0.30), and importance and value of PA (rho = 0.24-0.38; p < 0.05). Parenting practices associated with higher ST were rules around active play indoor (rho = 0.23), use of ST to reward/control behavior (rho = 0.30), exposure to screens (rho = 0.40), and explicit modeling/enjoyment of ST (rho = 0.50; p < 0.05). Conclusion: Recognized parenting practices such as explicit modeling of PA and ST, monitoring and limiting ST, and rules and restrictions about PA and ST are associated with young children's PA and ST in low-income Brazilian families. The findings identify potential targets for family-based interventions to promote healthy lifestyle behaviors and prevent childhood obesity.

Adherence to 24-hour movement guidelines among rural Brazalian preschool children: associations with parenting practices.

BACKGROUND: Young children residing in rural areas of low-and-middle income countries (LMICs) such as Brazil are at greater risk of obesity and related chronic health conditions. Yet, the extent to which rural preschool children from Brazil aged 3- to 6-years meet the World Health Organisation (WHO) 24-hour movement guidelines is unknown. Parents play a central role in the development of children's movement behaviors with logistic support, co-participation, modelling, and setting rules and limits recognized as influential parenting practices. However, the bulk of parenting research has been conducted in families from high income countries (HICs) and little is known about the relationship between parenting practices and children's movement behaviors in LMIC communities. Therefore, the aims of this study were two-fold: (1) report the proportion of preschool children from low-income families in rural Brazil meeting the WHO 24-hour movement guidelines; and (2) determine associations with theory-based parenting practices related to physical activity, screen time, and sleep. METHODS: A representative sample of 324 families from a rural district in north-eastern Brazil completed a validated, culturally adapted interviewer-administered survey assessing child physical activity, screen time and sleep, and associated parenting practices. The proportion of children meeting the physical activity, screen time, and sleep recommendations and all combinations of these recommendations was calculated. Forward selection logistic regression was used to determine which parenting practices were associated with meeting the individual recommendations and the 24-hour movement guidelines. RESULTS: Less than half of the children (47.5%) met the physical activity recommendation, 22% met the screen time recommendation, 62% met the sleep recommendation, with just over 10% meeting all three recommendations in the 24-h movement guidelines. Having fewer rules and restrictions around indoor and outdoor play, limiting, or monitoring screen time, and maintaining a consistent bedtime routine were key parenting practices associated with children´s adherence to the 24-hour movement guidelines. CONCLUSION: Only 1 in 10 rural Brazilian preschool children meet the 24-hour movement guidelines. These findings underscore the need for family-based interventions targeting parenting practices to support healthful movement behaviors in young children from LMICs.

Development, validation and item reduction of a food literacy questionnaire (IFLQ-19) with Australian adults.

BACKGROUND: Food literacy is theorised to improve diet quality, nutrition behaviours, social connectedness and food security. The definition and conceptualisation by Vidgen & Gallegos, consisting of 11 theoretical components within the four domains of planning and managing, selecting, preparing and eating, is currently the most highly cited framework. However, a valid and reliable questionnaire is needed to comprehensively measure this conceptualisation. Therefore, this study draws on existing item pools to develop a comprehensive food literacy questionnaire using item response theory. METHODS: Five hundred Australian adults were recruited in Study 1 to refine a food literacy item pool using principal component analysis (PCA) and item response theory (IRT) which involved detailed item analysis on targeting, responsiveness, validity and reliability. Another 500 participants were recruited in Study 2 to replicate item analysis on validity and reliability on the refined item pool, and 250 of these participants re-completed the food literacy questionnaire to determine its test-retest reliability. RESULTS: The PCA saw the 171-item pool reduced to 100-items across 19 statistical components of food literacy. After the thresholds of 26 items were combined, responses to the food literacy questionnaire had ordered thresholds (targeting), acceptable item locations (< -0.01 to + 1.53) and appropriateness of the measurement model (n = 92% expected responses) (responsiveness), met outfit mean-squares MSQ (0.48-1.42) (validity) and had high person, item separation (> 0.99) and test-retest (ICC 2,1 0.55-0.88) scores (reliability). CONCLUSIONS: We developed a 100-item food literacy questionnaire, the IFLQ-19 to comprehensively address the Vidgen & Gallegos theoretical domains and components with good targeting, responsiveness, reliability and validity in a diverse sample of Australian adults.

Core outcome set for early intervention trials to prevent obesity in childhood (COS-EPOCH): Agreement on "what" to measure.

BACKGROUND: Heterogeneity in the outcomes collected and reported in trials of interventions to prevent obesity in the first five years of life highlights the need for a core outcome set to streamline intervention evaluation and synthesis of effects. This study aimed to develop a core outcome set for use in early childhood obesity prevention intervention studies in children from birth to five years of age (COS-EPOCH). METHODS: The development of the core outcome set followed published guidelines and consisted of three stages: (1) systematic scoping review of outcomes collected and reported in early childhood obesity prevention trials; (2) e-Delphi study with stakeholders to prioritise outcomes; (3) meeting with stakeholders to reach consensus on outcomes. Stakeholders included parents/caregivers of children aged ≤ five years, policy-makers/funders, researchers, health professionals, and community and organisational stakeholders interested in obesity prevention interventions. RESULTS: Twenty-two outcomes from nine outcome domains (anthropometry, dietary intake, sedentary behaviour, physical activity, sleep, outcomes in parents/caregivers, environmental, emotional/cognitive functioning, economics) were included in the core outcome set: infant tummy time; child diet quality, dietary intake, fruit and vegetable intake, non-core food intake, non-core beverage intake, meal patterns, weight-based anthropometry, screentime, time spent sedentary, physical activity, sleep duration, wellbeing; parent/caregiver physical activity, sleep and nutrition parenting practices; food environment, sedentary behaviour or physical activity home environment, family meal environment, early childhood education and care environment, household food security; economic evaluation. CONCLUSIONS: The systematic stakeholder-informed study identified the minimum outcomes recommended for collection and reporting in early childhood obesity prevention trials. Future work will investigate the recommended instruments to measure each of these outcomes. The core outcome set will standardise guidance on the measurement and reporting of outcomes from early childhood obesity prevention interventions, to better facilitate evidence comparison and synthesis, and maximise the value of data collected across studies.
