Evaluation of a long day care intervention targeting the mealtime environment and curriculum to increase children's vegetable intake: a cluster randomised controlled trial using the multiphase optimisation strategy framework.

OBJECTIVE: To determine the reach, adoption, implementation and effectiveness of an intervention to increase children's vegetable intake in long day care (LDC). DESIGN: A 12-week pragmatic cluster randomised controlled trial, informed by the multiphase optimisation strategy (MOST), targeting the mealtime environment and curriculum. Children's vegetable intake and variety was measured at follow-up using a modified Short Food Survey for early childhood education and care and analysed using a two-part mixed model for non-vegetable and vegetable consumers. Outcome measures were based on the RE-AIM framework. SETTING: Australian LDC centres. PARTICIPANTS: Thirty-nine centres, 120 educators and 719 children at follow-up. RESULTS: There was no difference between intervention and waitlist control groups in the likelihood of consuming any vegetables when compared with non-vegetable consumers for intake (OR = 0·70, (95 % CI 0·34-1·43), P = 0·32) or variety (OR = 0·73 (95 % CI 0·40-1·32), P = 0·29). Among vegetable consumers (n 652), there was no difference between groups in vegetable variety (exp(b): 1·07 (95 % CI:0·88-1·32, P = 0·49) or vegetable intake (exp(b): 1·06 (95 % CI: 0·78, 1·43)), P = 0·71) with an average of 1·51 (95 % CI 1·20-1·82) and 1·40 (95 % CI 1·08-1·72) serves of vegetables per day in the intervention and control group, respectively. Intervention educators reported higher skills for promoting vegetables at mealtimes, and knowledge and skills for teaching the curriculum, than control (all P < 0·001). Intervention fidelity was moderate (n 16/20 and n 15/16 centres used the Mealtime environment and Curriculum, respectively) with good acceptability among educators. The intervention reached 307/8556 centres nationally and was adopted by 22 % eligible centres. CONCLUSIONS: The pragmatic self-delivered online intervention positively impacted educator's knowledge and skills and was considered acceptable and feasible. Intervention adaptations, using the MOST cyclic approach, could improve intervention impact on children' vegetable intake.

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.

Unpacking the cost of the lunchbox for Australian families: a secondary analysis.

Ninety per cent of Australian school children bring a home-packed lunch to school, with 44% of the food consumed during school hours being unhealthy. Among other factors, cost is a key consideration for food provision; however, the costs to Australian families are not well understood. Therefore, we aimed to determine what families are currently paying for school lunchboxes in Australian primary schools and to examine associations between food costs and socio-demographic factors with dietary quality. An audit of local retail outlets was used to determine the food costs of lunchbox contents. Costs (AUD) were adjusted for inflation as of early 2023. The lunchboxes of 1026 children aged 4-12 years at 12 Catholic primary schools in New South Wales, Australia, were assessed at the start of the day, using photography assessment methods and a validated School Food Checklist. The mean cost of lunchbox contents was $4.48 AUD (SD 1.53), containing a mean energy of 2699 kJ (SD 859), with 37.3% (SD 23.9) of energy sourced from unhealthy foods. Multiple linear regression analyses found that the strongest predictors of higher lunchbox cost (P < 0.05) were a higher proportion of energy from unhealthy foods (B = 0.016) and lower Socio-Economic Indexes for Areas (B = -0.178), when controlling for child socio-demographics. The results indicated that lunchbox food costs to Australian families are comparable to alternative school food service models in Australia and internationally. Results demonstrate the cost of food is not the only barrier to providing a healthy school lunchbox. Demonstrating a need for cost-considerate systematic interventions addressing food provision challenges and socio-economic disparities faced by families.

How and where does "care" fit within seminal life-course approaches? A narrative review and critical analysis.

AIMS: To map the concepts of the caring life-course theory that are used in life-course approaches from different disciplines; establish whether there is a common recognition of, or language used, to describe care in those life-course approaches; and identify the role and contribution of care to the life-course literature. DESIGN: This discursive paper uses a narrative review process to explore points of convergence and divergence between life-course approaches and the caring life-course theory. METHODS: Categories for analysis were developed deductively and inductively, focusing on the constructs of fundamental care, capacity and capability, care network, care transition, care trajectory and care biography. RESULTS: We identified four disciplinary perspectives: (1) life-course sociology; (2) life-course epidemiology; (3) lifespan developmental psychology; and (4) life-course health development. While six core constructs of the caring life-course theory were described, either explicitly or implicitly, in existing life-course approaches, no single approach fully describes the role and contribution of care across the lifespan. CONCLUSION: Life-course approaches have largely neglected the contribution and role of care in informing the life-course discourse. This review highlights the significance of care beyond traditional healthcare settings and recognizes it as a fundamental human need for well-being and development, which can contribute to existing life-course literature. IMPLICATION FOR THE PROFESSION AND/OR PATIENT CARE: There is a need to understand care as a complex system and embrace a whole-system, life-course approach to enable nurses and other healthcare professionals to provide high-quality, patient-centred care. IMPACT: Incorporating care within a life-course approach provides opportunities to integrate and deliver care centred around the person, their life transitions, trajectories and care networks, including informal carers and healthcare professionals. NO PATIENT OR PUBLIC CONTRIBUTION: Patients or members of the public were not involved in this study as it is a discursive paper based on the relevant literature.

Sources and determinants of free sugars intake by 5-year-old Australian children in the SMILE cohort.

Reducing free sugars intake is important for the prevention of dental caries and obesity in children. The study aimed to determine the amount and sources of free sugars known to contribute to dental caries, and identify sociodemographic determinants of intake by children aged 5 years in Australia. Cross-sectional analysis of dietary data from a cohort study, collected using a customized food frequency questionnaire were used to calculate free sugars intake as grams/day and percentage contribution to Estimated Energy Requirement (EER). The percent contribution of food sources to free sugars intake was derived. Sociodemographic determinants of achieving intakes within WHO thresholds (i.e., <5% and <10% Energy were explored with multinomial logistic regression. Complete data were available for 641 children (347 boys, 294 girls). Median (IQR) free sugars intake (g/day) was 31.6 (21.3-47.6) in boys and 28.1 (19.6-47.9) in girls. The median (IQR) percentage contribution to EER was 7.9 (5.4-12.7); 21% and 42% of children had intakes <5% EER and between 5% and <10%, respectively. The main sources of free sugars were: (1) Cakes, Biscuits and Cereal Bars; (2) Sweetened Milk Products (predominantly yoghurts) and (3) Desserts. Maternal university education, single-parent household, and maternal place of birth being Australia or New Zealand were associated with free sugars intake <5% EER. In conclusion, less than a quarter of 5-year-old children in the SMILE cohort achieved the WHO recommendations to limit free sugars to <5% EER. Strategies to lower free sugars intake could target priority populations such migrants, populations with lower levels of education or health literacy and identify areas for intervention in the wider food environments that children are exposed to.

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.

Evaluation of a menu box delivery service for Australian long-day care services to improve food provision and child intake: a cluster randomised controlled trial.

OBJECTIVE: To evaluate the impact of a menu box delivery service tailored to the long-day care (LDC) setting on improving menu compliance with recommendations, children's diet quality and dietary intake while in care. DESIGN: A cluster randomised controlled trial in LDC centres randomly assigned to an intervention (menu box delivery) or comparison (menu planning training) group. The primary outcome was child food provision and dietary intake. Secondary outcomes include menu compliance and process evaluation, including acceptability, fidelity and menu cost (per child, per day). SETTING: South Australian LDC centres. PARTICIPANTS: Eight LDC centres (n 224 children) provided data. RESULTS: No differences were observed in serves/d between intervention and comparison centres, for provision (intervention, 0·9 inter-quartile range (IQR) 0·7-1·2; comparison, 0·8 IQR 0·5-1·3) or consumption (intervention, 0·5 IQR 0·2-0·8; comparison, 0·5 IQR 0·3-0·9) of vegetables. Child food provision and dietary intake were similar across both groups for all food groups (P < 0·05). At follow-up, all intervention centres met menu planning guidelines for vegetables, whereas only one comparison centre met guidelines. Intervention centre directors found the menu box delivery more acceptable than cooks. Cost of the intervention was AUD$2·34 greater than comparison centres (intervention, AUD$4·62 (95 % CI ($4·58, $4·67)); comparison, AUD$2·28 (95 % CI ($2·27, $2·30)) per child, per day). CONCLUSIONS: Menu compliance can be improved via a menu delivery service, delivering equivalent impacts on child food provision and dietary intake compared with an online training programme. Further exploration of cooks acceptability and cost is essential before scaling up to implementation.

Development and internal validation of the SMILE-FSS: a Free Sugars Screener for Australian children aged 2 and 5 years.

OBJECTIVE: To develop and internally validate a Free Sugars Screener (FSS) for Australian children aged 2 and 5 years. DESIGN: Using data collected from a ninety-nine-item (2-year-olds) and ninety-eight-item (5-year-olds) FFQ in the Study of Mothers' and Infants' Life Events affecting oral health (SMILE-FFQ), a regression-based prediction modelling approach was employed to identify a subset of items that accurately estimate total free sugars intake (FSI). The predictors were grams of free sugars (FSg) for individual items in the SMILE-FFQ and child's age and sex. The outcome variable was total FSI per person. To internally validate the SMILE-FSS items, the estimated FSg was converted to percent energy from free sugars (%EFS) for comparison to the WHO free sugars guideline categories (< 5 %, 5-< 10 % and ≥ 10 %EFS) using cross-classification analysis. SETTING: Australia. PARTICIPANTS: 858 and 652 2- and 5-year-old children, respectively, with complete dietary (< 5 % missing) and sociodemographic data. RESULTS: Twenty-two and twenty-six items were important in predicting FSI at 2 and 5 years, respectively. Items were similar between ages with more discretionary beverage items (e.g. sugar-sweetened beverages) at 5 years. %EFS was overestimated by 4·4 % and 2·6 %. Most children (75 % and 82 %) were categorised into the same WHO free sugars category with most (87 % and 95 %) correctly identified as having < 10 %EFS in line with the WHO recommendation. CONCLUSIONS: The SMILE-FSS has good internal validity and can be used in research and practice to estimate young Australian children's FSI and compare to the WHO free sugars guidelines to identify those 'at risk'.

Development of an initiatives package to increase children's vegetable intake in long day care centres using the Multiphase Optimisation Strategy (MOST) randomised factorial experiment.

OBJECTIVE: To inform a package of initiatives to increase children's vegetable intake while in long day care (LDC) by evaluating the independent and combined effects of three initiatives targeting food provision, the mealtime environment and the curriculum. DESIGN: Using the Multiphase Optimisation Strategy (MOST) framework, a 12-week, eight-condition (n 7 intervention, n 1 control) randomised factorial experiment was conducted. Children's dietary intake data were measured pre- and post-initiative implementation using the weighed plate waste method (1× meal and 2× between-meal snacks). Vegetable intake (g/d) was calculated from vegetable provision and waste. The optimal combination of initiatives was determined using a linear mixed-effects model comparing between-group vegetable intake at follow-up, while considering initiative fidelity and acceptability. SETTING: LDC centres in metropolitan Adelaide, South Australia. PARTICIPANTS: 32 centres, 276 staff and 1039 children aged 2-5 years. RESULTS: There were no statistically significant differences between any of the intervention groups and the control group for vegetable intake (all P > 0·05). The curriculum with mealtime environment group consumed 26·7 g more vegetables/child/day than control (ratio of geometric mean 3·29 (95 % CI 0·96, 11·27), P = 0·06). Completion rates for the curriculum (> 93 %) and mealtime environment (61 %) initiatives were high, and acceptability was good (4/5 would recommend), compared with the food provision initiative (0-50 % completed the menu assessment, 3/5 would recommend). CONCLUSION: A programme targeting the curriculum and mealtime environment in LDC may be useful to increase children's vegetable intake. Determining the effectiveness of this optimised package in a randomised controlled trial is required, as per the evaluation phase of the MOST framework.

Changes in fitness and fatness in Australian schoolchildren during the summer holidays: fitness lost, fatness regained? A cohort study.

BACKGROUND: Emerging evidence suggests that children's fatness increases and fitness declines at a greater rate during the summer holiday period, compared with the school year. The aim of this study was to compare rates of change in fitness and fatness over the in-term and summer holiday periods among Australian schoolchildren. A secondary aim was to explore whether rates of change differed according to the child's sex, socio-economic status (SES), pubertal status and weight status. METHODS: Children (n = 381) initially in Grade 4 (age 9) were recruited for this 2-year longitudinal study. Fatness (% body fat, BMI z-score, waist-to-height ratio) and fitness (20-m shuttle run and standing broad jump) were measured at the start and end of two consecutive years. Rates of change were calculated for the two in-school periods (Grades 4 and 5) and for the summer holiday period. Rates of change in fatness and fitness between in-school and holiday periods were compared, and differences in rates of change according to sex, socio-economic status, and weight status were explored. RESULTS: During the holidays, percentage body fat increased at a greater rate (annualised rate of change [RoC]: +3.9 vs. Grade 4 and + 4.7 vs. Grade 5), and aerobic fitness declined at a greater rate (RoC - 4.7 vs. Grade 4 and - 4.4 vs. Grade 5), than during the in-school periods. There were no differences in rates of change for BMI z-score, waist-to-height ratio or standing broad jump. Body fatness increased faster in the holidays (relative to the in-school period) in children who are overweight and from low-SES families. Aerobic fitness declined more rapidly in the holidays in children who are overweight. CONCLUSION: This study highlights that during the summer holiday period, children experience greater increases in fatness and declines in fitness, with children who live with low-SES families and are overweight being more affected. The findings suggest the need for targeted interventions during this period to address these negative health trends.

Barriers and enablers to the family meal across time; a grounded theory study comparing South Australian parents' perspectives.

Family meals are positively associated with numerous beneficial health and social outcomes. Current discourse however claims that parents are faced with numerous barriers when trying to bring the family together to share a meal. Solutions for overcoming barriers to a positive shared family meal are often individualistic and do not address the systemic pressures and burdens families have faced for decades. The aim of this study was to explore the systemic and novel barriers and enablers to shared family meals as experienced by families across time. To achieve this, a qualitative study informed by grounded theory was conducted. Parents of South Australian families were recruited and interviewed in the 1990s, and a new sample of parents were recruited and interviewed in 2020. Transcripts were analysed using grounded theory and comparative analysis methods. Thirty-two parents from 16 families were interviewed in the 1990s, and 22 parents from 10 families in 2020. Ten factors were identified presenting as either enablers or barriers to the family meal, depending on the context they were experienced. Barriers and enablers were largely consistent across time. Scheduling and flexibility, children's disruptions and children's independence, privileges required to have family meals and motivation and commitment to the family meal were identified as persistent enablers and barriers across time. These findings indicate that parents are faced with similar challenges they have been facing for decades and are still not being adequately supported to execute family meals regularly. Recognising that factors present as either barriers or enablers to the family meal provides us with opportunities to transform barriers to enablers and support families to have regular, meaningful family meals.

The family meal, a ritual frozen in time; an Australian grounded theory study.

Family meals are recognized as an opportunity to promote the health of families. Popular discourse posits that changes to contemporary family life have made family meals harder to achieve and promotion of the 'traditional' family meal may be adding pressures to contemporary families. While research has been conducted on family meals over the last three decades, there is no explicit investigation of the experiences and practices of family meals over this time. Understanding the evolution of family meal practices across time is important for developing achievable expectations in relation to this ritual. Qualitative interviews were conducted with a diverse population of South Australian parents in the 1990s (n = 32) and with a separate population of parents in 2020 (n = 22) to gather their experiences of family meal practices. A comparative analysis, informed by grounded theory, was undertaken to identify similarities and differences in experiences across these two time periods. The results indicated stability in many family meal experiences across time, particularly in their value and significance in family life. Negotiations balancing time, cost, food preferences and responsibility persisted. The stability of family meal values and practices is important to consider when making recommendations, designing interventions and creating services targeting the family meal.

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.

Parental work hours and household income as determinants of unhealthy food and beverage intake in young Australian children.

OBJECTIVE: This study examined parental work hours and household income as determinants of discretionary (energy dense, nutrient poor) food and beverage intake in young children, including differences by eating occasion. DESIGN: Secondary analysis of cross-sectional data. Three hierarchical regression models were conducted with percent energy from discretionary food and beverages across the day, at main meals, and at snack times being the outcomes. Dietary intake was assessed by 1x24-hour recall and 1-2x24-hour food record(s). Both maternal/paternal work hours were included, and total household income. Covariates included household, parent and child factors. SETTING: Data from the NOURISH/SAIDI studies were collected between 2008-13. PARTICIPANTS: Participants included 526 mother-child dyads (median(IQR) child age 1.99(1.96,2.03) years). Forty-one percent of mothers did not work while 57% of fathers worked 35-40 hours/week. Most (85%) households had an income of ≥$50k AUD/year. RESULTS: Household income was consistently inversely associated with discretionary energy intake (ß= -0.12 to -0.15). Maternal part-time employment (21-35 hours/week) predicted child consumption of discretionary energy at main meals (ß=0.10, p=0.04). Paternal unemployment predicted a lower proportion of discretionary energy at snacks (ß= -0.09, p=0.047). CONCLUSIONS: This work suggests that household income should be addressed as a key opportunity-related barrier to healthy food provision in families of young children. Strategies to reduce the time burden of healthy main meal provision may be required in families where mothers juggle longer part-time working hours with caregiving and domestic duties. The need to consider the role of fathers and other parents/caregivers in shaping children's intake was also highlighted.

The Family Meal Framework: A grounded theory study conceptualising the work that underpins the family meal.

The family meal has been recognised as an integral part of family life. With the positive health outcomes associated with the family meal, it has been proposed as a strategy for encouraging health-promoting behaviours. However, a detailed understanding of the physical and mental work required to execute the family meal is lacking. The aim of this research was to conduct a grounded theory study to understand the components required to successfully execute the family meal. Two temporal data sets (1993-4/2020) in which diverse participants were sampled were used for this study. Methods used to conduct qualitative interviews with parents in the 1990s were mirrored in the conduct of qualitative interviews with parents in 2020. The interview data was analysed drawing on grounded theory methodology and methods. The entire sample included 54 parents from 28 families. A conceptual framework, 'The Family Meal Framework', was developed from the analyses. The five main components of The Framework are the cognitions (invisible work considering the needs of the family), actions (physical tasks required for the family meal), outcomes (the event of the family meal), the beliefs and feelings (expectations and attitudes toward the family meal), and the person(s) responsible (who undertakes the work). This framework provides a novel theory describing the reactive, cyclical nature of the work required to execute the family meal. This new understanding provides discrete opportunities for intervention in family meal research, practice, policy and promotion.

Towards a unifying caring life-course theory for better self-care and caring solutions: A discussion paper.

AIM: To present the first iteration of the caring life-course theory. BACKGROUND: Despite requiring care from birth to death, a person's universal or fundamental care needs and the subsequent care provision, either by self or others, has yet to be presented within a life-course perspective. Accurately describing the care people require across their lifespan enables us to identify who, what type, how and where this care should be provided. This novel perspective can help to legitimise a person's care needs and the support they require from wider care systems and contexts. DESIGN: Discussion paper outlines theory development. We adopted an inductive approach to theory development, drawing upon existing literature and the team's diverse experiences. Our theoretical insights were refined through a series of collaborative meetings to define the theory's constructs, until theoretical saturation was reached. DISCUSSION: Fourteen constructs are identified as essential to the theory. We propose it is possible, using these constructs, to generate caring life-course trajectories and predict divergences in these trajectories. The novel contribution of the theory is the interplay between understanding a person's care needs and provision within the context of their lifespan and personal histories, termed their care biography, and understanding a person's care needs and provision at specific points in time within a given care network and socio-political context. IMPACT FOR NURSING: The caring life-course theory can provide a roadmap to inform nursing and other care industry sectors, providing opportunities to integrate and deliver care from the perspective of the person and their care history, trajectories and networks, with those of professional care teams. It can help to shape health, social and economic policy and involve individuals, families and communities in more constructive ways of talking about the importance of care for improved quality of life and healthy societies.

The food and nutrient intake of 5- to 12-year-old Australian children during school hours: a secondary analysis of the 2011-2012 National Nutrition and Physical Activity Survey.

OBJECTIVE: School food intake of Australian children is not comprehensively described in literature, with limited temporal, nationally representative data. Greater understanding of intake at school can inform school-based nutrition promotion. This study aimed to describe the dietary intake of primary-aged children during school hours and its contribution to daily intake. DESIGN: This secondary analysis used nationally representative, cross-sectional data from the 2011 to 2012 National Nutrition and Physical Activity Survey. Dietary intake was assessed using validated 24-h dietary recalls on school days. Descriptive statistics were undertaken to determine energy, nutrients, food groups and food products consumed during school hours, as well as their contributions to total daily intake. Associations between school food intake and socio-demographic characteristics were explored. SETTING: Australia. PARTICIPANTS: Seven hundred and ninety-five children aged 5-12 years. RESULTS: Children consumed 37 % of their daily energy and 31-43 % of select nutrient intake during school hours, with discretionary choices contributing 44 % of school energy intake. Most children consumed less than one serve of vegetables, meat and alternatives or milk and alternatives during school hours. Commonly consumed products were discretionary choices (34 %, including biscuits, processed meat), bread (17 %) and fruit (12 %). There were limited associations with socio-economic position variables, apart from child age. CONCLUSIONS: Children's diets were not aligned with national recommendations, with school food characterised by high intake of discretionary choices. These findings are consistent with previous Australian evidence and support transformation of the Australian school food system to better align school food consumption with recommendations.

Identifying opportunities for strengthening advice to enhance vegetable liking in the early years of life: qualitative consensus and triangulation methods.

OBJECTIVE: To prioritise and refine a set of evidence-informed statements into advice messages to promote vegetable liking in early childhood, and to determine applicability for dissemination of advice to relevant audiences. DESIGN: A nominal group technique (NGT) workshop and a Delphi survey were conducted to prioritise and achieve consensus (≥70 % agreement) on thirty evidence-informed maternal (perinatal and lactation stage), infant (complementary feeding stage) and early years (family diet stage) vegetable-related advice messages. Messages were validated via triangulation analysis against the strength of evidence from an Umbrella review of strategies to increase children's vegetable liking, and gaps in advice from a Desktop review of vegetable feeding advice. SETTING: Australia. PARTICIPANTS: A purposeful sample of key stakeholders (NGT workshop, n 8 experts; Delphi survey, n 23 end users). RESULTS: Participant consensus identified the most highly ranked priority messages associated with the strategies of: 'in-utero exposure' (perinatal and lactation, n 56 points) and 'vegetable variety' (complementary feeding, n 97 points; family diet, n 139 points). Triangulation revealed two strategies ('repeated exposure' and 'variety') and their associated advice messages suitable for policy and practice, twelve for research and four for food industry. CONCLUSIONS: Supported by national and state feeding guideline documents and resources, the advice messages relating to 'repeated exposure' and 'variety' to increase vegetable liking can be communicated to families and caregivers by healthcare practitioners. The food industry provides a vehicle for advice promotion and product development. Further research, where stronger evidence is needed, could further inform strategies for policy and practice, and food industry application.

Study protocol for Healthy Conversations @ Playgroup: a multi-site cluster randomized controlled trial of an intervention to promote healthy lifestyle behaviours in young children attending community playgroups.

BACKGROUND: Early childhood is a critical window for preventing obesity and chronic disease. Yet, 1 in 4 Australian children aged 5 years and under are affected by overweight or obesity; and significant proportions of children under 5 years fail to meet guidelines for diet quality, physical activity (PA), screen time, and sleep. Consequently, effective interventions to promote healthy lifestyle behaviors and prevent obesity during early childhood are needed. Community playgroups provide an opportunity for parents, carers, and children to meet in a safe and relaxed environment to play and share information. The structure, low cost and reach of playgroups provide a unique platform to engage parents in a scalable program to promote healthful lifestyle behaviors and prevent childhood obesity. However, the evidence base for the effectiveness of health promotion programs delivered in community playgroup settings is limited and lacking credible evidence from rigorously conducted randomized controlled trials. METHODS: The Healthy Conversations @ Playgroup randomized controlled trial (RCT) aims to address the underlying behavioral risk factors for obesity by helping parents take effective steps to improve their child's dietary, PA, screen time, and sleep behaviors. The intervention program comprises 10 "healthy conversations" led by a trained peer facilitator, designed to increase parents' behavioral capability and self-efficacy to implement autonomy-supportive parenting practices. The program will be delivered biweekly during regularly scheduled playgroup sessions over 10-weeks. Effectiveness will be tested in a 2-arm cluster RCT involving 60 community playgroups in three states across Australia. After baseline assessments, participating playgroups will be randomly allocated to either intervention or wait-list control conditions. Primary outcomes (vegetable intake, discretionary foods, daily PA, screen time, sleep duration, and body mass index [BMI] z-score) will be assessed at baseline, immediately post-intervention (10-weeks; T2) and 6-months post-intervention (T3). Outcomes will be assessed for differential change at T2 and T3. DISCUSSION: The Healthy Conversations @ Playgroup trial will rigorously evaluate a novel peer-led intervention program to promote healthful lifestyle behaviors and prevent obesity in children and families attending community playgroups. If effective, the program could be immediately scaled-up and delivered in community playgroups across Australia. TRIAL REGISTRATION: Trial registered 22nd January 2021 with the Australian and New Zealand Clinical Trials Registry ( ACTRN12621000055808 ).

Understanding the influence of physical resources and social supports on primary food providers' snack food provision: a discrete choice experiment.

BACKGROUND: Snack eating occasions contribute approximately a third of children's energy intake, with approximately half of all unhealthy foods consumed during snack times. Therefore, it is critical to understand the drivers of primary food providers' snack provision. The study aims were to determine the relative importance of physical resources and social supports when primary food providers are choosing snacks to provide to their child, and to investigate how these attributes differ in social versus non-social occasions, and between subgroups of primary food providers based on socio-economic position. METHODS: Primary food providers of three to seven-year olds completed an online discrete choice experiment, by making trade-offs when completing repeated, hypothetical choice tasks on the choice of snacks to provide to their child in: 1) non-social and 2) social condition. Choice tasks included two alternatives consisting of varying attribute (i.e. factor) levels, and an opt-out option. The order of conditions shown were randomized across participants. Multinomial logit model analyses were used to determine utility weights for each attribute. RESULTS: Two-hundred and twenty-five primary food providers completed the study, providing 1125 choice decisions per condition. In the non-social condition, the top three ranked attributes were type of food (utility weight 1.94, p < 0.001), child resistance (- 1.62, p < 0.001) and co-parent support (0.99, p < 0.001). In the social condition, top ranking attributes were child resistance (utility weight - 1.50, p < 0.001), type of food (1.38, p < 0.001) and co-parent support (1.07, p < 0.001). In both conditions, time was not a significant influence and cost was of lowest relative importance. Subgroup analyses revealed cost was not a significant influence for families from higher socio-economic backgrounds. CONCLUSIONS: Type of food, child resistance and co-parent support were of greatest relative importance in primary food providers' snack provision decision-making, regardless of social condition or socio-economic position. In designing future interventions to reduce unhealthy snacks, researchers should prioritize these influences, to better support primary food providers in changing their physical and social opportunity.
