An mHealth Intervention to Reduce the Packing of Discretionary Foods in Children's Lunch Boxes in Early Childhood Education and Care Services: Cluster Randomized Controlled Trial

Background

Interventions in early childhood education and care (ECEC) services have the potential to improve children’s diet at the population level.

Objective

This study aims to test the efficacy of a mobile health intervention in ECEC services to reduce parent packing of foods high in saturated fat, sugar, and sodium (discretionary foods) in children’s (aged 3-6 years) lunch boxes.

Methods

A cluster randomized controlled trial was undertaken with 355 parent and child dyads recruited by phone and in person from 17 ECEC services (8 [47%] intervention and 9 [53%] control services). Parents in the intervention group received a 10-week fully automated program targeting barriers to packing healthy lunch boxes delivered via an existing service communication app. The program included weekly push notifications, within-app messages, and links to further resources, including websites and videos. The control group did not receive any intervention. The primary outcomes were kilojoules from discretionary foods and associated nutrients (saturated fat, free sugars, and sodium) packed in children’s lunch boxes. Secondary outcomes included consumption of kilojoules from discretionary foods and related nutrients and the packing and consumption of serves of discretionary foods and core food groups. Photography and weights of foods in children’s lunch boxes were recorded by trained researchers before and after the trial to assess primary and secondary outcomes. Outcome assessors were blinded to service allocation. Feasibility, appropriateness, and acceptability were assessed via an ECEC service manager survey and a parent web-based survey. Use of the app was assessed via app analytics.

Results

Data on packed lunch box contents were collected for 88.8% (355/400) of consenting children at baseline and 84.3% (337/400) of children after the intervention. There was no significant difference between groups in kilojoule from discretionary foods packed (77.84 kJ, 95% CI −163.49 to 319.18; P=.53) or the other primary or secondary outcomes. The per-protocol analysis, including only data from children of parents who downloaded the app, also did not find any statistically significant change in primary (−1.98 kJ, 95% CI −343.87 to 339.90; P=.86) or secondary outcomes. Approximately 61.8% (102/165) of parents in the intervention group downloaded the app, and the mean service viewing rate of weekly within-app messages was 26% (SD 14.9). Parents who responded to the survey and participating services agreed that it was appropriate to receive lunch box information via the app (40/50, 80% and 6/8, 75%, respectively).

Conclusions

The intervention was unable to demonstrate an impact on kilojoules or associated nutrients from discretionary foods packed in children’s lunch boxes. Low app downloads and program message views indicate a need to explore how to improve factors related to implementation before further testing similar mobile health interventions in this setting.

Feasibility of a Web-Based Implementation Intervention to Improve Child Dietary Intake in Early Childhood Education and Care: Pilot Randomized Controlled Trial

Background

Internationally, the implementation of evidence-based healthy eating policies and practices within early childhood education and care (ECEC) settings that encourage children’s healthy diet is recommended. Despite the existence of evidence-based healthy eating practices, research indicates that current implementation rates are inadequate. Web-based approaches provide a potentially effective and less costly approach to support ECEC staff with implementing nutrition policies and practices.

Objective

The broad aim of this pilot randomized controlled trial is to assess the feasibility of assessing the impact of a web-based program together with health promotion officer (HPO) support on ECEC center implementation of healthy eating policies and practices. Specifically, we seek to describe the completion rate of study evaluation processes (participant consent and data collection rates); examine ECEC center uptake, acceptability, and appropriateness of the intervention and implementation strategies; understand the potential cost of delivering and receiving implementation support strategies; and describe the potential impact of the web-based intervention on the implementation of targeted healthy eating practices among centers in the intervention group.

Methods

A 6-month pilot implementation trial using a cluster-randomized controlled trial design was conducted in 22 ECEC centers within the Hunter New England region of New South Wales, Australia. Potentially eligible centers were distributed a recruitment package and telephoned by the research team to assess eligibility and obtain consent. Centers randomly allocated to the intervention group received access to a web-based program, together with HPO support (eg, educational outreach visit and local technical assistance) to implement 5 healthy eating practices. The web-based program incorporated audit with feedback, development of formal implementation blueprints, and educational materials to facilitate improvement in implementation. The centers allocated to the control group received the usual care.

Results

Of the 57 centers approached for the study, 22 (47%) provided consent to participate. Data collection components were completed by 100% (22/22) of the centers. High uptake for implementation strategies provided by HPOs (10/11, 91% to 11/11, 100%) and the web-based program (11/11, 100%) was observed. At follow-up, intervention centers had logged on to the program at an average of 5.18 (SD 2.52) times. The web-based program and implementation support strategies were highly acceptable (10/11, 91% to 11/11, 100%). Implementation of 4 healthy eating practices improved in the intervention group, ranging from 19% (2/11) to 64% (7/11).

Conclusions

This study provides promising pilot data to warrant the conduct of a fully powered implementation trial to assess the impact of the program on ECEC healthy eating practice implementation.

A cross-sectional study of packed lunchbox foods and their consumption by children in early childhood education and care services

AIM

To (a) describe lunchbox foods packed and consumed by children attending early childhood education and care services; (b) compare the serves of foods packed and consumed with nutrition guideline recommendations; and (c) explore associations between parent characteristics and serves of food groups packed in lunchboxes.

METHODS

A cross sectional study was conducted on a sample of early childhood education and care services where parents provide food in the Hunter New England region of NSW, Australia. Lunchbox contents were assessed using photography and pre- and post-meal weights. Descriptive statistics were used to describe packing and consumption of core food groups and discretionary foods.

RESULTS

Data on food packed and consumed were collected for 355 children's lunchboxes from 17 services (preschools n = 14, long day care services n = 3). Less than half (44%) of lunchboxes contained vegetables, and 54% contained at least one serve of discretionary foods. Less than 1% of lunchboxes met all setting-specific nutrition guidelines. On average, children consumed 68% of lunchbox contents, with the lowest consumption rate being for vegetables. An association was found between parent education level and packing of discretionary foods (-0.36, P = <.01) but not for packing of fruit or vegetables.

CONCLUSIONS

Lunchboxes contained an over-representation of discretionary foods and under-representation of vegetables, and children had a low preference for consuming vegetables compared with other food groups. Interventions to support parent packing of lunchboxes in line with nutrition guidelines and strategies to expand child preference for foods such as vegetables are warranted.

A Cluster Randomised Controlled Trial of an Intervention to Increase Physical Activity of Preschool-Aged Children Attending Early Childhood Education and Care: Study Protocol for the 'Everybody Energise' Trial

The use of ‘Energisers,’ short bouts of moderate-to-vigorous physical activity (MVPA), have been shown to significantly increase children’s physical activity within the school setting but not within Early Childhood Education and Care (ECEC) centres. The aim of this study is to assess the efficacy of an intervention involving the provision of educator-led daily Energisers to increase the time children spend in MVPA while attending ECEC. Fourteen ECEC centres in the Hunter region of New South Wales, Australia, will be randomised to either an intervention or control group. The intervention group will be supported by the research team to implement three brief (5-min) educator-led Energisers each day for children aged three to six years between the hours of 9:00 a.m. to 3.00 p.m. Control ECEC centres will continue to provide ‘normal practice’ to children. The primary trial outcome is child minutes of MVPA whilst in ECEC, assessed objectively via accelerometery over three days. Outcome assessment will occur at baseline and 6 months post-baseline. Linear mixed models under an intention-to-treat framework will be used to compare differences between groups in MVPA at follow-up. This will be the first cluster randomised controlled trial to test the efficacy of Energisers in isolation on increasing the time children spend in MVPA.

Implementation of continuous free play schedules in Australian childcare services: A cross-sectional study

ISSUE ADDRESSED

Modifying the scheduling of physical activity opportunities to provide children with more frequent opportunities for outdoor free play has been demonstrated to increase child physical activity while in care. The primary aim of this study was to describe the implementation of continuous free play schedules to allow children to access outdoor play areas, consistent with sector guidelines in a national sample of Australian childcare services. Secondary aims were to investigate the associations between the implementation of such schedules and service characteristics, and assess the perceived barriers and enablers to implementation.

METHODS

A cross-sectional study was undertaken with a random sample of 326 centre-based childcare services located across Australia. Childcare service characteristics, continuous free play scheduling and perceived barriers and enablers to implementation were assessed via a survey administered to service managers online or via telephone.

RESULTS

A total of 203 service managers (62%) reported implementing a continuous free play schedule, for three periods of 126 minutes per period, each day on average. Service type (long day care services), size (services with higher numbers of child enrolments [≥80 children]) and socio-economic area (services located in lower socio-economic areas) were associated with the implementation of a continuous free play schedule. The most prevalent barriers to implementation included insufficient staff to ensure adequate supervision of children (69%) and service layout being unsuitable (65%), while the most prevalent enablers included advice on how to overcome staffing or supervision issues (89%) and to re-orientate the service layout (54%).

CONCLUSIONS

There is scope to support the implementation of continuous free play schedules consistent with childcare sector guidelines. SO WHAT?: Future intervention research that targets the reported barriers and enablers to implementation is needed.

The Impact of a Childcare Food Service Intervention on Child Dietary Intake in Care: An Exploratory Cluster Randomized Controlled Trial

PURPOSE

To assess the efficacy of a food service implementation intervention designed to increase provision of foods consistent with nutrition guidelines on child consumption of fruit, vegetables, breads/cereals, meat/alternatives, dairy, and diet quality in care.

DESIGN

Exploratory cluster randomized controlled trial.

SETTING

Twenty-five childcare centers in New South Wales, Australia.

SAMPLE

Three hundred ninety-five children aged 2 to 5 years.

INTERVENTION

Centers were randomized to the intervention or control group. Intervention development was guided by the Theoretical Domains Framework and included securing executive support, provision of group training, resources, audit and feedback, and one-on-one support. The intervention was delivered across six months and the study was conducted between March and December 2016.

MEASURES

Child diet was assessed by educators using a validated questionnaire modified for completion in childcare center.

ANALYSIS

Data were analyzed in SAS using generalized linear mixed models adjusted for clustering.

RESULTS

Children in the intervention group consumed significantly higher number of serves of vegetables (0.4 serves; P < .001), wholegrain cereals (0.7 serves; P = .02), and meat/alternatives (0.5 serves; P < .001), and had higher diet quality scores (10.3; P < .001).

CONCLUSIONS

A food service intervention targeting the provision of food significantly improved child dietary intake in care. Such findings are relevant to health promotion practitioners responsible for supporting improvements in child diet.

Challenges of Increasing Childcare Center Compliance With Nutrition Guidelines: A Randomized Controlled Trial of an Intervention Providing Training, Written Menu Feedback, and Printed Resources

PURPOSE

To assess the effectiveness of an intervention including training, provision of written menu feedback, and printed resources on increasing childcare compliance with nutrition guidelines.

DESIGN

Parallel group randomized controlled trial.

SETTING

Hunter New England region, New South Wales, Australia.

PARTICIPANTS

Forty-four childcare centers that prepare and provide food on-site to children while in care.

INTERVENTION

The intervention was designed using the Theoretical Domains Framework, targeted managers, and cooks and included implementation strategies that addressed identified barriers.

MEASURES

Outcomes included the proportion of menus providing food servings (per child) compliant with overall nutrition guideline recommendations and each individual food group assessed via menu assessments. Cook knowledge of recommendations, intervention acceptability, adverse events, and barriers were also assessed via questionnaires with cooks and managers.

ANALYSIS

Logistic regression models, adjusted for baseline values of the outcome.

RESULTS

At baseline and follow-up, zero centers in the intervention and control groups were compliant with the overall menu guidelines or for the vegetable and meat food groups. Follow-up between-group differences in compliance for discretionary (33.3 vs 5, P = .18), dairy (41.7 vs 15, P = .16), breads and cereals (8.3 vs 10 P = 1.00), and fruit (16.7 vs 10, P = .48) were all nonsignificant. Relative to the control group, intervention centers showed a significantly greater increase in percentage of cooks with correct knowledge for vegetable servings (93.3 vs 36.4, P = .008).

CONCLUSION

Although the application of the theoretical framework produced a broader understanding of the determinants of menu compliance, due to the complexity of guidelines, limited follow-up support, lower training uptake, and low intervention dose, the intervention was not effective in supporting the practice change required.
