Participant recruitment and retention (R&R) are well-documented challenges in longitudinal studies, especially those involving populations historically underrepresented in research and vulnerable groups (e.g., pregnant people or young children and their families), as is the focus of the HEALthy Brain and Child Development (HBCD) birth cohort study. Subpar access to transportation, overnight lodging, childcare, or meals can compromise R&R; yet, guidance on how to overcome these “logistical barriers” is sparse. This study’s goal was to learn about the HBCD sites’ plans and develop best practice recommendations for the HBCD consortium for addressing these logistical barriers.

The HBCD’s workgroups developed a survey asking the HBCD sites about their plans for supporting research-related transportation, lodging, childcare, and meals, and about the presence of institutional policies to guide their approach. Descriptive statistics described the quantitative survey data. Qualitative survey responses were brief, not warranting formal qualitative analysis; their content was summarized.

Twenty-eight respondents, representing unique recruitment locations across the U.S., completed the survey. The results indicated substantial heterogeneity across the respondents in their approach toward supporting research-related transportation, lodging, childcare, and meals. Three respondents were aware of institutional policies guiding research-related transportation (10.7%) or childcare (10.7%).

This study highlighted heterogeneity in approaches and scarcity of institutional policies regarding research-related transportation, lodging, childcare, and meals, underscoring the need for guidance in this area to ensure equitable support of participant R&R across different settings and populations, so that participants are representative of the larger community, and increase research result validity and generalizability.

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.

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).

South Australian LDC centres.

Eight LDC centres (n 224 children) provided data.

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).

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.

To describe environmentally sustainable (ES) and healthy food provision practices in childcare services in Victoria, Australia.

Cross-sectional study.

Childcare services providing food onsite.

Staff completed an online survey that explored ES food provision practices including purchasing seasonal/local food, food waste awareness/management, and food cost/child/d. A purposively sampled subgroup conducted weighed audits to determine compliance with guidelines and total waste, serving waste (prepared, not served) and plate waste.

Survey results found 8 % of services (n 129) had previously conducted food waste audits. Service audits (n 12) found 27 % total food waste (range: 9 % - 64 %). Statistically significant differences in plate waste were found between services who had previously conducted food waste audits (7 %) and those who had not (17 %) (P = 0·04). The most common ES practice was ‘providing seasonal food’; the least common was ‘maintaining a compost system’ and ‘less packaged foods’. Most services (95 %) purchased foods from supermarkets with 23 % purchasing from farmers’ markets. This was statistically lower for regional/rural services (8 %), compared to metropolitan services (27 %) (P = 0·04). Twenty-seven per cent of services spent AUD2·50 or less per child per day on food. Only one audited service provided a menu compliant with childcare food provision guidelines.

Childcare settings procure and provide large volumes of food; however, food waste awareness appears limited, and environmentally sustainable food procurement practices may be less affordable and difficult to achieve. Understanding the impact of food waste awareness on food waste practices and food costs across time merits further research.

The federal Child and Adult Care Food Program (CACFP) sets minimum nutrition and portion size standards for meals served in participating childcare programs. CACFP has been associated with more nutritious meals served. It is unclear, however, whether CACFP results in children’s dietary intake being aligned with national recommendations. We assess whether children’s dietary intake in CACFP-participating childcare centres meets benchmarks set by the Dietary Guidelines for Americans (DGA).

This is a cross-sectional study. We used direct observation to estimate quantities of foods/beverages served and consumed per child. Mean amounts served per child per day were compared with CACFP portion size requirements for each component (fruits, vegetables, milk and meat/meat alternate). Mean amounts of foods/beverages consumed were compared with DGA recommendations (energy content, fruits, vegetables, whole/refined grains, dairy, protein and added sugars). One sample t-tests evaluated if quantities served and consumed were different from CACFP and DGA standards, respectively.

Six CACFP-participating childcare centres.

2–5 year-old children attending childcare.

We observed forty-six children across 166 child meals. Most meals served met CACFP nutrition standards. Compared with CACFP portion size standards, children were served more grains at breakfast and lunch; more fruits/vegetables at lunch but less at breakfast and snack and less dairy at all eating occasions. Compared with DGA recommendations, children under-consumed every food/beverage category except grains during at least one eating occasion.

Children were served quantities of foods/beverages mostly consistent with CACFP portion size requirements, but had sub-optimal intake relative to DGA. More research is needed to help children consume healthy diets in childcare.

To test a culturally tailored obesity prevention intervention in low-income, minority preschool age children.

A three-group clustered randomised controlled trial.

Twelve Head Start centres were randomly assigned to a centre-based intervention, a combined centre- and home-based intervention, or control using a 1:1:1 ratio. The centre-based intervention modified centre physical activity and nutrition policies, staff practices, and child behaviours, while the home-based intervention supported parents for obesity prevention at home.

The primary end point was change in children’s BMI (kg/m2) at post-test immediately following completion of the 8-month intervention. Secondary end points included standardised scores for BMI (BMIz) and body weight (WAZ), and BMI percentiles (BMI pctl).

Three-year-old children enrolled in Head Start in San Antonio, Texas, with written parent consent (n 325), 87 % Latino, 57 % female with mean age (sd) of 3·58 years (0·29).

Change in BMI at post-test was 1·28 (0·97), 1·28 (0·87) and 1·41 (0·71) in the centre + home-based intervention, centre-based intervention and control, respectively. There was no significant difference in BMI change between centre + home-based intervention and control or centre-based intervention and control at post-test. BMIz (adjusted difference –0·12 (95 % CI, –0·24, 0·01), P = 0·06) and WAZ (adjusted difference, –0·09 (–0·17, –0·002), P = 0·04) were reduced for children in centre + home-based intervention compared with control group.

There was no reduction in BMI at post-test in children who received the intervention. Findings shed light on methodological challenges in childhood obesity research and offer future directions to explore health equity-oriented obesity prevention.

This study assessed the level of fathers’ involvement in childcare activities and its association with the diet quality of their children in Northern Ghana.

The study was carried out in the Northern, Upper East and Upper West regions of Ghana. The people in the study area mostly depend on agriculture as their main occupation.

A community-based comparative analytical cross-sectional study.

A sample of 422 rural mother–father pairs who had at least one child aged 6–36 months.

The overall level of fathers’ involvement in childcare and feeding activities was high among 63·5 % of the respondents in the 6 months prior to the study. The most common childcare activity men were involved in was providing money for the purchase of food for the child. Minimum acceptable diet was higher for children with a higher level of paternal involvement in childcare activities (adjusted OR = 3·33 (95 % CI: 1·41, 7·90)), compared to their counterparts whose father’s involvement was poor. Fathers who had a positive attitude to childcare and feeding were 2·9 more likely to get involved in childcare activities (adjusted OR = 2·90 (95 % CI: 1·87, 4·48)).

The findings confirm earlier studies that show that fathers’ involvement in childcare activities including feeding is positively associated with improved child feeding practices. The findings point to the need to have a policy shift in which both men and women are key actors in interventions designed to improve child nutritional status in rural settings of Northern Ghana.

Previous studies have found long lasting cognitive delays among children with early childcare experience, especially institutionalised experience. However, little is known about institutions’ effect in late childhood.

Our goal is to identify the characteristics of cognitive functions in connection to attachment related anxiety among adopted children and children living in institutional care.

The participants’ (N=68, Mage=14.20, 29 boys and 39 girls) cognitive functions were measured with the following tests: Rey15 Memory Task, Knock And Tap Task, Simon Says Test, Verbal Fluency Task, D-KEFS 20 Questions Test. Participants completed two questionnaires: the Family Affluence Scale and the Experiences In Close Relationships Revised Scale. The results from the adopted children (N=19) and children living in institutional care (N=18) were compared to the matched control group: children living with their biological parents (N=31).

Children living in institutional care did not differ significantly from their (SES-based) matched controls. Children adopted after the age of 2 years (N=7, M =56,57month) and the low SES control group (N=14) differed from the high SES control group on tests of attention (Verbal Fluency Task, Mhigh.c.=212.50, Mad.aft.2=193.50, U=59.50, z=-2.62, p=0.009) and verbal memory (Rey15, Mhigh.c.=17.94, Mad.aft.2=9.18, U=35.00, z=-2.79, p=0.005). Children adopted before the age of 2 years differed from the high SES control as well, in inhibition (Simon Says Test, Mhigh.c.=12.26, Mad.bef.2=18.88, U=55.55, z=-2.23, p=0.026).

Our findings suggest that only in the early years is child protection experience associated with long-lasting cognitive delays and attachment related anxiety.

No significant relationships.

To explore government support service access, perceived barriers/enablers to menu planning and menu compliance in long day care (LDC) centres in Victoria, Australia, where the Victorian Government-funded Healthy Eating Advisory Service (HEAS) is available to provide free LDC menu planning support.

This is a cross-sectional study design. Data were collected from online surveys with the option of uploading 2 weeks of menus and recipes. Menu compliance was scored for quantity, quality and variety. Barriers/enablers to menu planning guideline implementation were determined using the Theoretical Domains Framework (TDF). Independent t tests, one-way ANOVA and chi-square tests assessed relationships between characteristics, barriers/enablers and menu scores.

Eighty-nine LDC centres that prepare food onsite.

LDC staff responsible for menu planning (n 89) and menus from eighteen centres.

Fifty-five per cent of centres had accessed HEAS. Of eighteen provided menus, only one menu was compliant with menu planning guidelines. HEAS access was associated with higher average scores in four of seven TDF domains, namely knowledge/awareness, skills/role, reinforcement/influence and optimism/intent. There were no correlations between menu score and barriers/enablers; however, menu quality scores were higher for those accessing HEAS.

Childcare-specific government support services may be an important public health nutrition strategy and may improve menu planning guideline implementation as well as menu quality; however, this does not necessarily translate into menu compliance. Research should confirm these findings in larger studies to ascertain uptake of these services. Public health efforts should focus on exploring barriers and enablers to uptake of government support services to increase reach and acceptability.

To determine whether the ‘Read for Nutrition’ programme would increase liking and consumption of broccoli (a target vegetable) in preschool children and test acceptability and practicality of the programme.

Pilot pre-post intervention study, where childcare teachers received training and coaching followed by reading the book ‘Monsters Don’t Eat Broccoli’ multiple times with the children during a three-week intervention.

Five classrooms of Educare, Lincoln, Nebraska in 2018.

Sixty-nine (11 to 16 children per classroom) preschool-aged children and sixteen teachers (minimum, three per classroom).

Average total consumption of broccoli increased 35 % (0·14 ounces or 0·05th cup) after the ‘Read for Nutrition’ programme (t = 2·66; P = 0·01; 95 % CIs (0·035, 0·246)) for all children. Proportional consumption increased for children who received ≥ five exposures to the book (t46 = 2·77; P = 0·008). Exposures to the book predicted proportional consumption (β = 0·365; P = 0·002). Liking of broccoli increased (W69 = 2·2, P = 0·03) as well. Teachers rated the programme as acceptable, practical and enjoyable to children and to themselves.

Programmes such as ‘Read for Nutrition’ have the potential to improve children’s vegetable liking and consumption in early care and education settings with only book readings and no exposure to a real vegetable.
