Assessment of nutrition and physical activity environments in family child care homes: modification and psychometric testing of the Environment and Policy Assessment and Observation

Children's physical activity in family child care homes: Influence of quality status, environment and policy features, and child characteristics

BACKGROUND

About half of preschool-age children are not meeting recommendations of 15 min/h of physical activity (PA), and nearly one out of seven children between the ages of 2-5 years are living with obesity. Furthermore, children attending family child care homes (FCCHs), compared with larger child care centers, engage in lower levels of PA and appear to be at a higher risk of obesity. Therefore, examining PA and multi-level factors that influence PA in children who attend FCCHs is essential.

METHODS

The Childcare Home Eating and Exercise Study (CHEER) examined PA behaviors of 184 children enrolled in 56 FCCHs and FCCH quality status, environment and policy features, and child characteristics. PA was assessed by accelerometer, and FCCH environment and policy was assessed via structured observation. Multiple linear regression was used to model associations between school day total PA and FCCH quality status, environment and policy features, and child characteristics.

RESULTS

Child participants were on average 3.1 years old; participants were non-Hispanic Black (47.3%), Non-Hispanic White (42.9%), other race/ethnicity (7.1%), and Hispanic/Latin (2.7%). Children in FCCH settings participated in 11.2 min/h of total PA, which is below the recommended 15 min per hour. The PA environment and policy observation yielded a score of 11.8 out of a possible 30, which is not supportive of child PA. There were no associations between total child PA and FCCH quality status, environment and policy features, and child characteristics in these FCCH settings.

CONCLUSIONS

This study was unique in its examination of PA and a comprehensive set of factors that may influence PA at the individual, organizational, environmental, and policy levels in a diverse sample of children attending FCCHs in South Carolina. Additional research is needed to better understand how to increase children's physical activity while they are in the FCCH setting. This research should use multi-level frameworks and apply longitudinal study designs.

Effectiveness of Interventions Promoting Dietary Intake, Physical Activity, and Healthy Weight Status of Children in Family Child Care: A Systematic Review

INTRODUCTION

This systematic review examines the effectiveness of interventions in family child care (FCC) on (1) children's dietary intake, physical activity levels and weight, and (2) FCC health-promoting environments, policies, and practices. Quasi-experimental studies measuring these outcomes were included.

METHODS

All available articles up to July 2023 were searched using MEDLINE, ERIC, CINAHL, Embase, Scopus, and A+ Education, and 15 interventions were included. Methodological quality was assessed with the Effective Public Health Practice Project Assessment tool.

RESULTS

Thirteen studies were weak, and 2 strong in quality. Four interventions included children's dietary intake as an outcome measure, 2 included physical activity, and 3 weight status. Twelve interventions assessed nutrition and 7 physical activity environmental outcomes.

DISCUSSION

Interventions in FCC improved children's dietary intake, but their impact on physical activity and weight status was inconclusive. Furthermore, positive impacts were observed in environmental outcomes related to nutrition, whereas research on physical activity environmental outcomes was limited.

IMPLICATIONS FOR RESEARCH AND PRACTICE

Future research could replicate interventions to validate effectiveness and understand positive outcome mechanisms. Future interventions might use FCC stakeholders' input, incorporate innovative physical activity components, enhance FCC providers' position as role models, involve parents, and target those groups that are at a high risk of being obese.

Advancing assessment of responsive feeding environments and practices in child care

Child care environments offer an ideal setting for feeding interventions. CELEBRATE Feeding is an approach implemented in child care environments in two Maritime Provinces in Canada to support responsive feeding (RF) to foster children's self-efficacy, self-regulation, and healthy relationships with food. This study aimed to describe RF in child care using established and enhanced scoring frameworks. The Environment and Policy Assessment and Observation (EPAO) was modified to reflect RF environments and practices, resulting in our modified EPAO and a CELEBRATE scale. Observations were conducted in 18 child care rooms. Behaviours and environments were scored on both scales, creating 21 RF scores, with a score of '3' indicating the most responsiveness. Descriptive analyses of the scores were conducted. The overall room averages were Mean (M) = 41.00, Standard Deviation (SD) = 7.07 (EPAO), and M = 37.92 SD = 6.50 (CELEBRATE). Most responsive scores among rooms within our EPAO and CELEBRATE scales, respectively, were 'educators not using food to calm or encourage behaviour' (M = 2.94, SD = 0.24; M = 2.98, SD = 0.06) and 'not requiring children to sit at the table until finished' (M = 2.89, SD = 0.47; M = 2.97, SD = 0.12). The least responsive scores within the EPAO were 'educator prompts for children to drink water' (M = 0.78, SD = 0.94) and 'children self-serving' (M = 0.83, SD = 0.38). The least responsive in the CELEBRATE scale were 'enthusiastic role modelling during mealtime' (M = 0.70, SD = 0.68) and 'praise of mealtime behaviour unrelated to food intake' (M = 0.74, SD = 0.55). The CELEBRATE scale captured unique observation information about RF to allow documenting change over time with detailed measurement to inform and support nutrition interventions within child care environments.

Policies, Practices, and Environmental Characteristics Among Family Child Care Homes in South Carolina

Background: Child care program requirements have adopted nutrition and physical activity standards to address childhood obesity, but few studies have examined the effects of these standards in family child care homes (FCCHs). Methods: In a cross-sectional study (2017-2019), the Childcare Home Eating and Exercise study examined self-reported provider characteristics and observed policies and practices related to physical activity and nutrition in FCCHs in South Carolina. Two-sample t-tests were used to compare observed nutrition and physical activity policy, practice, and environment scores in child care homes that participated in versus did not participate in the state's ABC Quality program, which is designed to improve child care and includes policies and practices intended to increase physical activity levels and improve diet quality. Results: Environment and Policy Assessment and Observation results for nutrition and physical activity were 7.5 out of 21 and 11.8 out of 30, respectively, indicating much room for improvement in nutrition and physical activity policies, practices, and environment in South Carolina FCCHs. The study found one difference between FCCHs that did and did not participate in the ABC Quality program; non-ABC homes provided more time for physical activity. Conclusions: Future research should develop ways to strengthen the guidelines and improve the implementation of obesity prevention standards in FCCHs.

Mediation of the association between social environmental characteristics of family childcare home and weight status in children by diet quality

BACKGROUND

The food and beverages served in family childcare homes (FCCHs) may play an important role in the development of childhood overweight and obesity. This analysis examines whether children's diet quality mediates the relationship between foods and beverages served in FCCHs and preschool-aged children's weight status.

METHODS

Trained and certified staff conducted observations for two days in each FCCH, using the Environment and Policy Assessment and Observation (EPAO) measure to determine the foods and beverages served to children (N = 370) in FCCHs (N = 120). They also used the Dietary Observation in Child Care (DOCC) protocol to assess children's food and beverage intake during childcare, from which we calculated the Healthy Eating Index-2015 (HEI), a measure of diet quality. Height and weight were measured for each child with parent consent from which the child's body mass index (BMI) z-scores were calculated. A multilevel mediation analysis was conducted to indicate whether children's diet quality mediates the relations between food and beverage served in FCCHs and preschool-aged children's weight status.

RESULTS

Children's total HEI scores significantly mediated the relationship between the EPAO subscale Food Provided and children's BMI z-scores (B=-0.01, p < .05, 95% CI = [-0.03, - 0.002]). Further, the EPAO subscale Food Provided was positively associated with the total HEI score (B = 0.75, p < .01, 95% CI = [0.32, 1.18]). Total HEI scores were negatively associated with BMI z-score (B=-0.01, p < .05, 95% CI = [-0.02, - 0.001]).

CONCLUSION

Children's diet quality did significantly mediate the relationship between the food served in FCCHs and children's weight status. More longitudinal studies with longer follow-up periods need to be conducted to confirm these relationships. Further, future studies need to examine the relationships between a broader spectrum of FCCH environmental characteristics and home environment with children's weight status, as well as other mediators including physical activity.

Mediation of the Association between Social Environmental Characteristics of Family Childcare Home and Weight Status in Children by Diet Quality

Background

The food and beverages served in family childcare homes (FCCHs) may play an important role in the development of childhood overweight and obesity. This analysis examines whether children's diet quality mediates the relationship between foods and beverages served in FCCHs and preschool-aged children's weight status.

Methods

Trained and certified staff conducted observations for two days in each FCCH, using the Environment and Policy Assessment and Observation (EPAO) measure to determine the foods and beverages served to children (N=370) in FCCHs (N=120). They also used the Dietary Observation in Child Care (DOCC) protocol to assess children's food and beverage intake during childcare, from which we calculated the Healthy Eating Index-2015 (HEI), a measure of diet quality. Height and weight were measured for each child with parent consent from which the child's body mass index (BMI) z-scores were calculated from. A multilevel mediation analysis was conducted to indicate whether children's diet quality mediates the relations between food and beverage served in FCCHs and preschool-aged children's weight status.

Results

Children's total HEI scores significantly mediated the relationship between the EPAO subscale "Food provided" and children's BMI z-scores (B=-.01, p<.05, 95% CI = [-.03, -.002]). Further, the EPAO subscale "Food provided" was positively associated with the total HEI score (B=.75, p<.01, 95% CI = [.32, 1.18]). Total HEI scores were negatively associated with BMI z-score (B=-.01, p<.05, 95% CI = [-.02, -.001]).

Conclusion

Children's diet quality did significantly mediate the relationship between the food served in FCCHs and children's weight status. More longitudinal studies with longer follow-up periods need to be conducted to confirm these relationships. Further, future studies need to examine the relationships between a broader spectrum of FCCH environmental characteristics and home environment with children's weight status, as well as other mediators including physical activity.

Early childhood eating behaviors associated with risk of overweight and its socio-ecological determinants in Korean preschool children

BACKGROUND/OBJECTIVES

This study aimed to identify preschool children's eating behaviors associated with early childhood obesity and its multi-level, socio-ecological determinants.

SUBJECTS/METHODS

In a cross-sectional study of 364 mothers of preschool children aged 3-5 years, these children's healthy eating behaviors were assessed using a validated preschool nutrition quotient (NQ-P) questionnaire. The children's overweight or obesity statuses were determined based on body mass index percentiles from the 2017 Korean National Growth Chart. The associations between the NQ-P score and risk of overweight or obesity were examined using multivariable logistic regression. The associations of individual, maternal, physical, and media environmental factors with the NQ-P score were also examined using multivariable linear regression.

RESULTS

Preschool children with greater NQ-P scores were at a significantly lower risk of overweight or obesity (P < 0.01). The NQ-P score had a significantly positive association with maternal body mass index and an inverse association with household income (all P < 0.05). Maternal parenting and feeding practices exhibited associations with the NQ-P score. Positive associations were observed with "warm," "structured," and "autonomy-supportive" parenting as well as monitoring feeding practices (all P < 0.05). In addition, the NQ-P score had a significantly positive association with the childcare center's anti-obesogenic environment, such as the provision of nutritional and physical-activity support and vicinity of the built food environment to the home, including access to good-quality food, fruits and vegetables, and low-fat foods (all P < 0.05). Regarding media environments, the NQ-P score demonstrated more significant associations with viewing and eating and/or cooking content displayed on online video platforms (all P < 0.05) than with that on television.

CONCLUSIONS

Our findings confirm the significance of healthy eating behaviors in early-childhood-obesity prevention and underscore the importance of multilevel maternal, physical, and media environmental interventions that effectively guide eating behaviors in preschool children.

Nutrition Practices of Family Child Care Home Providers and Children's Diet Quality

OBJECTIVE

To examine the relationship between the diet quality of children aged 2-5 years cared for in family child care homes (FCCHs) with provider adherence to nutrition best practices.

DESIGN

Cross-sectional analysis.

PARTICIPANTS

Family child care home providers (n = 120, 100% female, 67.5% Latinx) and children (n = 370, 51% female, 58% Latinx) enrolled in a cluster-randomized trial.

MAIN OUTCOME MEASURES

Data were collected over 2 days at each FCCH. The Environment and Policy Assessment and Observation tool was used to document whether providers exhibited nutrition practices on the basis of the Nutrition and Physical Activity Self-Assessment for Child Care. Each practice was scored as either present or absent. Children's food intake was observed using Diet Observation at Child Care and analyzed with the Healthy Eating Index-2015.

ANALYSIS

Multilevel linear regression models assessed the association between providers exhibiting best practices regarding nutrition and children's diet quality. The model accounted for clustering by FCCH and controlled for provider ethnicity, income level, and multiple comparisons.

RESULTS

Children in FCCHs in which more of the best practices were implemented had higher diet quality (B = 1.05; 95% confidence interval [CI], 0.12-1.99; P = 0.03). Specifically, children whose providers promoted autonomous feeding (B = 27.52; 95% CI, 21.02-34.02; P < 0.001) and provided nutrition education (B = 7.76; 95% CI, 3.29-12.23; P = 0.001) had higher total Healthy Eating Index scores.

CONCLUSIONS AND IMPLICATIONS

Future interventions and policies could support FCCH providers in implementing important practices such as autonomy feeding practices, talking informally to children about nutrition, and providing healthful foods and beverages.

Feeding and Activity Environments for Infants and Toddlers in Childcare Centers and Family Childcare Homes in Southeastern New England

Few studies have documented the food and physical activity (PA) environments of childcare settings caring for children <24 months of age, although they may be key contributors to developing child PA and diet patterns. We used an adapted Environment and Policy Assessment and Observation tool to assess the food and activity environments for infants and toddlers in childcare centers (n = 21) and family childcare homes (FCCH) (n = 20) and explored differences by childcare type. Many similarities were found between childcare site types; however, centers used more recommended feeding practices than FCCH (e.g., 100% of center providers talked with toddlers about feelings of hunger or fullness compared to 18% of family childcare providers (FCCP), p < 0.01). Differences in non-recommended feeding practices (e.g., spoon feeding, bottle propping and encouraging unhealthy foods) were mixed between childcare types. Toddlers in centers spent more time playing at higher PA levels than those in FCCH (61 vs. 13 min, p < 0.001). Screen time was observed in FCCH, but not in centers. Differences between childcare types may indicate differential influences on infant and toddler feeding and PA behaviors, which could predict disparate obesity risk. Future research should further observe these behaviors in a larger sample of centers and FCCH to inform childcare interventions and policies.

Assessment of Feeding Practices and Mealtime Environments in Australian Family Daycare Services

OBJECTIVE

Assess educators' feeding practices and mealtime environments in family daycare services and examine the factors associated with educators' feeding practices and mealtime environments.

METHODS

Cross-sectional observational study of family daycare services (n = 33) in Australia. Best practices for mealtime environments and educator feeding practices were assessed during each mealtime using the Environment Policy Assessment and Observation instrument. Correlates assessed via survey included: socioeconomic status, main language spoken at home, early childhood career experience, and nutrition professional development. Descriptive statistics and independent t tests were calculated.

RESULTS

Educators typically had higher scores, indicating better practices, for (the absence of) negative practices compared with positive practices. The only positive practice meeting best-practice standards was educators sitting with children during the meal. There were no significant correlations for educators' feeding practices or mealtime environment.

CONCLUSIONS AND IMPLICATIONS

Educators may benefit from professional development targeting positive feeding practices and supportive mealtime environments.

A multi-component tailored intervention in family childcare homes improves diet quality and sedentary behavior of preschool children compared to an attention control: results from the Healthy Start-Comienzos Sanos cluster randomized trial

Background

Childcare settings are important environments for influencing child eating and physical activity (PA). Family childcare homes (FCCH) care for many children of low-income and diverse racial/ethnic backgrounds who are at greater risk for poor diet quality, low PA, and obesity, but few interventions have targeted this setting. The aim of this study was to assess the efficacy of a multicomponent intervention conducted in FCCH on the diet quality and PA of 2–5 year old children in their care.

Trial design

Cluster randomized trial.

Methods

The cluster-randomized trial, Healthy Start/Comienzos Sanos (2015–2019) evaluated an 8-month nutrition and PA intervention that included four components: (1) monthly telephone calls from a support coach using brief motivational interviewing, (2) tailored reports, newsletters and videos, (3) group support meetings, and (4) active play toys. After completing baseline measurement, FCCH were randomized into intervention or comparison groups in matched pairs. Both groups received the same intervention components but on different topics (intervention: nutrition/PA vs. comparison: reading readiness/literacy). Evaluation staff were blinded to group assignment. Child primary outcome measures collected at baseline and 8-months included: 1) Healthy Eating Index (HEI-2015) scores calculated from diet observation, and 2) accelerometer measurement of PA. Process measures were collected from field data and provider surveys. Generalized Estimating Equation Models assessed changes in HEI-2015 scores and PA over time by experimental condition.

Results

Ethnically diverse FCCH providers (n = 119) and 2-to-5-year-old children in their care (n = 377) were included in the final analysis. Process evaluation showed high participation in all intervention components except for group meetings. Compared to children in comparison group FCCH, children in intervention FCCH increased total HEI-2015 scores by 7.2 points (p < .001) including improvement in component scores for vegetables (0.84 points, p = .025) and added sugar (0.94 points, p = .025). For PA, compared to children in the comparison group, children in intervention FCCH decreased sedentary time by 5.7% (p = .021).

Conclusions

The multicomponent Healthy Start intervention was effective in improving diet quality and sedentary behavior of children in FCCH, which demonstrates the promise of obesity prevention interventions in this setting. Future research could include enhancing the Healthy Start intervention to strengthen the PA component, considering virtual peer support, and determining how to best translate and disseminate the intervention into FCCH nationally.

Food Outlet Density, Distance, and Food Quality Offered to Preschool-Aged Children at Family Child Care Homes

OBJECTIVE

To examine how food environments around family child care homes (FCCHs) are associated with the healthfulness of foods served to children.

DESIGN

Cross-sectional data from a mail survey of FCCH providers, InfoUSA.

PARTICIPANTS

The study included 132 Mississippi FCCHs (26% response).

MAIN OUTCOME MEASURES

Dependent: compliance with nutrition best practices for 9 food categories; composite healthfulness score. Independent: counts of supermarkets, small-medium grocery stores, produce stores, convenience stores within 5 miles; distance to supermarket.

ANALYSIS

Logistic regression estimated associations between best-practice compliance and food environment. Linear regression estimated associations between composite food healthfulness and food environment. Models stratified by rural/urban location.

RESULTS

Rural FCCHs with higher counts of supermarkets, convenience stores, and produce stores had lower compliance with selected best practices (fried/prefried potatoes, high-sugar/high-fat foods). Urban FCCHs with more supermarkets had higher compliance with fruit not canned in syrup; those with more small-medium grocery stores and convenience stores had lower compliance with selected best practices (fried/prefried potatoes, vegetables, low-fat meats).

CONCLUSIONS AND IMPLICATIONS

Food environment measures were associated with some nutrition best practices, though not consistently in the expected direction. Future research could examine food quality at stores near rural FCCHs. Programs that improve local food environments may improve foods served at FCCHs.

Quality of Nutrition Environments, Menus and Foods Served, and Food Program Achievement in Oklahoma Family Child Care Homes

Child care environments foster children's healthy eating habits by providing exposure to healthy foods and feeding practices. We assessed the healthfulness of nutrition environments, menu/meal quality, and the achievement of Child and Adult Care Food Program (CACFP) guidelines and best practices in Oklahoma CACFP-enrolled family child care homes (FCCHs) (n = 51). Two-day classroom observations were conducted. Healthfulness of classroom nutrition environments was assessed using the Environment and Policy Assessment and Observation (EPAO). Foods served to and consumed by children were quantified using the Dietary Observations in Child Care (DOCC) tool. Nutrient analysis was performed to determine total energy for foods listed on menus, served to, and consumed by children. Menu and meal food variety and CACFP Guideline Achievement Scores were determined. Average nutrition environment score was 11.7 ± 1.2 (61.5% of maximum possible score). Energy (kcals) from menus and consumed by children was insufficient to meet two-thirds of their daily reference intake. Children were exposed to 1.7 vegetables and 1.3 fruits per meal. CACFP Guideline Achievement Scores were 66.3% ± 7.8 for menus and 59.3% ± 7.6 for mealtimes. Similar to previous research, our findings indicate a need for improved FCCH nutrition practices. Tailored interventions for FCCHs are needed.

Assessing the implementation of healthy eating and physical activity policies and practices in the family day care setting: A cross-sectional study

ISSUE ADDRESSED

While the family day care setting provides a unique opportunity to improve child health, few studies have assessed obesity prevention practices of this setting. This study aimed to examine the (a) prevalence of implementation of evidence-based healthy eating and physical activity policies and practices among schemes (ie overarching governing agency) and educators in the family day care setting in Australia; and (b) associations between educator socio-demographic characteristics and implementation of healthy eating and physical activity practices.

METHODS

Family day care schemes (n = 16) responsible for educators (n = 174) located in the Hunter New England region of NSW participated in a telephone survey in 2018, reporting their implementation of evidence-based healthy eating and physical activity policies and practices. Linear mixed regression analyses were used to determine whether educator characteristics were associated with higher percentages of implementation.

RESULTS

Few schemes had comprehensive breastfeeding (0%) and screen time (19%) policies. However, the majority of educators (81%) communicated with families when lunchboxes were not consistent with guidelines. Educators implemented an average of 64.3% of practices assessed. Educators located in higher socioeconomic areas implemented a significantly higher percentage of practices than those in lower socioeconomic areas (P < .000). Educator years of experience was positively associated with percentage of implementation (P = .009).

CONCLUSIONS

The implementation of obesity prevention policies and practices in the family day care setting is variable and associated with educator socio-demographic characteristics. SO WHAT?: There is a need to support family day care schemes to improve their obesity prevention environments, particularly those related to policies.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Testing the effects of interventions to increase consumption of fruit and vegetables, including those focused on specific child-feeding strategies or broader multicomponent interventions targeting the home or childcare environment is required to assess the potential to reduce this disease burden.

OBJECTIVES

To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and two clinical trials registries to identify eligible trials on 25 January 2020. We searched Proquest Dissertations and Theses in November 2019. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included trials to identify further potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risks of bias of included trials; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included 80 trials with 218 trial arms and 12,965 participants. Fifty trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fifteen trials examined the impact of parent nutrition education only in increasing child fruit and vegetable intake. Fourteen trials examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. Two trials examined the effect of a nutrition education intervention delivered to children in increasing child fruit and vegetable intake. One trial examined the impact of a child-focused mindfulness intervention in increasing vegetable intake. We judged 23 of the 80 included trials as free from high risks of bias across all domains. Performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining trials. There is low-quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption, equivalent to an increase of 5.30 grams as-desired consumption of vegetables (SMD 0.50, 95% CI 0.29 to 0.71; 19 trials, 2140 participants; mean post-intervention follow-up = 8.3 weeks). Multicomponent interventions versus no intervention has a small effect on child consumption of fruit and vegetables (SMD 0.32, 95% CI 0.09 to 0.55; 9 trials, 2961 participants; moderate-quality evidence; mean post-intervention follow-up = 5.4 weeks), equivalent to an increase of 0.34 cups of fruit and vegetables a day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.13, 95% CI -0.02 to 0.28; 11 trials, 3050 participants; very low-quality evidence; mean post-intervention follow-up = 13.2 weeks). We were unable to pool child nutrition education interventions in meta-analysis; both trials reported a positive intervention effect on child consumption of fruit and vegetables (low-quality evidence). Very few trials reported long-term effectiveness (6 trials), cost effectiveness (1 trial) or unintended adverse consequences of interventions (2 trials), limiting our ability to assess these outcomes. Trials reported receiving governmental or charitable funds, except for four trials reporting industry funding.

AUTHORS' CONCLUSIONS

Despite identifying 80 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains limited in terms of quality of evidence and magnitude of effect. Of the types of interventions identified, there was moderate-quality evidence that multicomponent interventions probably lead to, and low-quality evidence that child-feeding practice may lead to, only small increases in fruit and vegetable consumption in children aged five years and under. It is uncertain whether parent nutrition education or child nutrition education interventions alone are effective in increasing fruit and vegetable consumption in children aged five years and under. Our confidence in effect estimates for all intervention approaches, with the exception of multicomponent interventions, is limited on the basis of the very low to low-quality evidence. Long-term follow-up of at least 12 months is required and future research should adopt more rigorous methods to advance the field. This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available. Please refer to the Cochrane Database of Systematic Reviews for the current status of this review.

Child Care Setting and Its Association With Policies and Practices That Promote Physical Activity and Physical Literacy in the Early Years in British Columbia

BACKGROUND

Physical activity (PA) is critical to early child development, and child care is a key setting for promotion. The authors investigated differences in daily PA and sedentary behavior practices as well as physical environments between family child care (FCC) and group child care (GCC) settings for children aged 3-5 years in Canada.

METHODS

Group child care (n = 581) and FCC (n = 357) managers completed surveys assessing the implementation of PA promoting practices and description of their environments. Crosstabulation and chi-square tests of association were used to examine differences between GCC and FCC.

RESULTS

The prevalence of facilities implementing 120 minutes of active play (odds ratio [OR] 2.23; 95% confidence interval [CI], 1.58-3.15), <30 minutes on screens (OR 1.35; 95% CI, 1.02-1.80), and 60-minute outdoors daily (OR 1.99; 95% CI, 1.4-2.9) was more likely in FCC compared with GCC. However, implementation of fundamental movement skill activities (OR 1.40; 95% CI, 1.01-1.92), breaking up prolonged sitting (OR 1.86; 95% CI, 1.36-2.5), and outdoor space for large group running games (OR 1.74; 95% CI, 1.07-2.83) were more likely in GCC.

CONCLUSIONS

Child care setting was associated with daily PA and sedentary practices and outdoor space for PA. Interventions to support PA in child care should be tailored to different settings and the facilitators explored.

Keys to healthy family child care homes: Results from a cluster randomized trial

Early care and education settings, such as family child care homes (FCCHs), are important venues for children's health promotion. Keys to Healthy Family Child Care Homes evaluated a FCCH-based intervention's impact on children's diet and physical activity. This study enrolled 496 children aged 1.5-4 years and 166 FCCH providers into a cluster-randomized control trial (intervention = 242 children/83 FCCHs, control = 254 children/83 FCCHs) conducted during 2013-2016. The 9-month intervention addressed provider health, health of the FCCH environment, and business practices, and was delivered through three workshops, three home visits, and nine phone calls. The attention control arm received a business-focused intervention. Primary outcomes were children's diet quality (2 days of observed intakes summarized into Healthy Eating Index scores) and moderate to vigorous physical activity (3 days of accelerometry) at the FCCH. Secondary outcomes were child body mass index (BMI), FCCH provider health behaviors, and FCCH nutrition and physical activity environments and business practices. Repeated measures analysis, using an intent-to-treat approach, accounting for clustering of children within FCCHs and adjusting for child age, sex, and BMI, was used to evaluate change (completed in 2018). Compared to controls, intervention children significantly improved their diet quality (5.39, p = .0002, CI = 2.53, 8.26) but not MVPA (0.31, p = .195, CI = -0.16, 0.79). Intervention FCCH providers significantly improved their diet quality and several components of their FCCH environment (i.e., time provided for physical activity, use of supportive physical activity practices, and engagement in nutrition and physical activity education/professional development). FCCHs are malleable settings for health promotion, especially diet quality. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.govNCT01814215.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Interventions to increase consumption of fruit and vegetables, such as those focused on specific child-feeding strategies and parent nutrition education interventions in early childhood may therefore be an effective strategy in reducing this disease burden.

OBJECTIVES

To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and two clinical trials registries to identify eligible trials on 25 August 2019. We searched Proquest Dissertations and Theses in May 2019. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included trials to identify further potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risks of bias of included trials; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included 78 trials with 214 trial arms and 13,746 participants. Forty-eight trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fifteen trials examined the impact of parent nutrition education in increasing child fruit and vegetable intake. Fourteen trials examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. Two trials examined the effect of a nutrition education intervention delivered to children in increasing child fruit and vegetable intake. One trial examined the impact of a child-focused mindfulness intervention in increasing vegetable intake. We judged 20 of the 78 included trials as free from high risks of bias across all domains. Performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining trials. There is very low-quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption equivalent to an increase of 4.45 g as-desired consumption of vegetables (SMD 0.42, 95% CI 0.23 to 0.60; 18 trials, 2004 participants; mean post-intervention follow-up = 8.2 weeks). Multicomponent interventions versus no intervention has a small effect on child consumption of fruit and vegetables (SMD 0.34, 95% CI 0.10 to 0.57; 9 trials, 3022 participants; moderate-quality evidence; mean post-intervention follow-up = 5.4 weeks), equivalent to an increase of 0.36 cups of fruit and vegetables per day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.12, 95% CI -0.03 to 0.28; 11 trials, 3078 participants; very low-quality evidence; mean post-intervention follow-up = 13.2 weeks). We were unable to pool child nutrition education interventions in meta-analysis; both trials reported a positive intervention effect on child consumption of fruit and vegetables (low-quality evidence). Very few trials reported long-term effectiveness (6 trials), cost effectiveness (1 trial) and unintended adverse consequences of interventions (2 trials), limiting their assessment. Trials reported receiving governmental or charitable funds, except for four trials reporting industry funding.

AUTHORS' CONCLUSIONS

Despite identifying 78 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains limited. There was very low-quality evidence that child-feeding practice may lead to, and moderate-quality evidence that multicomponent interventions probably lead to small increases in fruit and vegetable consumption in children aged five years and younger. It is uncertain whether parent nutrition education interventions are effective in increasing fruit and vegetable consumption in children aged five years and younger. Given that the quality of the evidence is very low or low, future research will likely change estimates and conclusions. Long-term follow-up of at least 12 months is required and future research should adopt more rigorous methods to advance the field. This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available.

Improving nutrition and physical activity environments of family child care homes: the rationale, design and study protocol of the 'Healthy Start/Comienzos Sanos' cluster randomized trial

BACKGROUND

Early childhood is a crucial time to foster healthy eating and physical activity (PA) habits, which are critical for optimal child health, growth and development. Child care facilities are important settings to promote healthy eating and PA and prevent childhood obesity; however, almost all prior intervention studies have focused on child care centers and not family child care homes (FCCH), which care for over 1.6 million U.S. children.

METHODS

This paper describes Healthy Start/Comienzos Sanos, a cluster-randomized trial evaluating the efficacy of a multicomponent intervention to improve nutrition and PA environments in English and Spanish-speaking FCCH. Eligible child care providers complete baseline surveys and receive a two-day FCCH observation of the home environment and provider practices. Parent-consented 2-5 year-old children are measured (height, weight, waist circumference), wear accelerometers and have their dietary intake observed during child care using validated protocols. FCCH providers are then randomly assigned to receive an 8-month intervention including written materials tailored to the FCCH providers' need and interest, videos, peer support coaching using brief motivational interviewing, and periodic group meetings focused on either nutrition and PA (Intervention) or reading readiness (Comparison). Intervention materials focus on evidence-based nutrition and physical activity best practices. The initial measures (surveys, two-day observation of the FCCH and provider practices, child diet observation, physical measures, and accelerometer) are assessed again 8 and 12 months after the intervention starts. Primary outcomes are children's diet quality (Healthy Eating Index), time in moderate and vigorous PA and sedentary PA during child care. Secondary outcomes include FCCH provider practices and foods served, and PA environments and practices. Possible mediators (provider attitudes, self-efficacy, barriers and facilitators) are also being explored. Process evaluation measures to assess reach, fidelity and dose, and their relationship with dietary and PA outcomes are included.

DISCUSSION

Healthy Start/Comienzos Sanos fills an important gap in the field of childhood obesity prevention by rigorously evaluating an innovative multicomponent intervention to improve the nutrition and physical activity environments of FCCH.

Nutrition-Related Practices of Family Child Care Providers and Differences by Ethnicity

BACKGROUND

Child care settings play an important role in shaping children's eating behaviors; yet few studies have included family child care homes (FCCHs). We examined provider-reported nutrition-related practices in FCCHs and observed adherence to nutrition guidelines from the Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC), exploring differences by provider ethnicity.

METHODS

We assessed baseline data from a cluster-randomized trial, including surveys with FCCH providers and observational data collected at the FCCH. We examined provider-reported nutrition-related practices and if providers met NAP SACC guidelines using observational data. Differences by ethnicity were assessed using chi-square and multivariate log-linear analysis adjusting for education.

RESULTS

Providers completed a telephone survey (n = 166, 100% female and 72% Hispanic) and participated in 2 full-day observations (n = 119). Many providers reported engaging in positive nutrition-related practices. Significant differences by ethnicity included the following: Hispanic providers less likely to report feeding practices that were responsive to children's self-regulation, but also less likely to report eating and drinking unhealthy foods/beverages in front of children and having screens on during meals and more likely to report seeking nutrition trainings. Using observational data, only 10 of 26 NAP SACC practices were met by >60% of providers. Few ethnic differences in meeting guidelines were found (7 of 26 practices).

CONCLUSIONS

While providers engage in some positive nutrition practices, improvement is needed to ensure that all providers actually meet evidence-based guidelines. Ethnic differences in certain practices underscore the need for culturally relevant trainings.

Physical Activity and Sedentary Behaviors of Children in Family Child Care Homes: Are There Opportunities for Improvement?

PURPOSE

Many children attend family child care homes (FCCHs), an important setting to influence children's physical activity (PA) and sedentary behavior (SB). This study assessed children's PA and SB while in FCCHs, characteristics of the FCCH PA environment, and relationships between the environment and child PA and SB.

METHOD

Children ages 1.5-4.0 years (n = 495) were recruited from 165 FCCHs in North Carolina. Children's moderate to vigorous PA and SB were measured via accelerometry for 3 days. FCCH PA environments were assessed over 2 days using the Environment and Policy Assessment and Observation for FCCHs. Ten subscores and an overall PA environment score (possible range: 0-30) were calculated; higher scores indicate better quality.

RESULTS

Children accumulated 30 (13) minutes of moderate to vigorous PA and 143 (42) minutes of SB in FCCHs daily. FCCHs scored low on the Environment and Policy Assessment and Observation for FCCHs, with an average overall score of 13 (2). FCCHs scored highest on screen time and screen time practices subscores, and lowest on PA education/professional development and PA policy subscores. Although no statistically significant associations were observed, some large Cohen d effect sizes were noted (eg, outdoor playtime subscore and moderate to vigorous PA).

CONCLUSIONS

This study highlights opportunities to improve FCCHs and increase children's behaviors (eg, providing adequate time and outdoor play spaces).

Modifying the Environment and Policy Assessment and Observation (EPAO) to better capture feeding practices of family childcare home providers

OBJECTIVE

To describe the modification and validation of an existing instrument, the Environment and Policy Assessment and Observation (EPAO), to better capture provider feeding practices.

DESIGN

Modifications to the EPAO were made, validity assessed through expert review, pilot tested and then used to collect follow-up data during a two-day home visit from an ongoing cluster-randomized trial. Exploratory factor analysis investigated the underlying factor structure of the feeding practices. To test predictive validity of the factors, multilevel mixed models examined associations between factors and child's diet quality as captured by the Healthy Eating Index-2010 (HEI-2010) score (measured via the Dietary Observation in Childcare Protocol).

SETTING

Family childcare homes (FCCH) in Rhode Island and North Carolina, USA.ParticipantsThe modified EPAO was pilot tested with fifty-three FCCH and then used to collect data in 133 FCCH.

RESULTS

The final three-factor solution ('coercive control and indulgent feeding practices', 'autonomy support practices', 'negative role modelling') captured 43 % of total variance. In multilevel mixed models adjusted for covariates, 'autonomy support practices' was positively associated with children's diet quality. A 1-unit increase in the use of 'autonomy support practices' was associated with a 9·4-unit increase in child HEI-2010 score (P=0·001).

CONCLUSIONS

Similar to the parenting literature, constructs which describe coercive controlling practices and those which describe autonomy-supportive practices emerged. Given that diets of pre-schoolers in the USA remain suboptimal, teaching childcare providers about supportive feeding practices may help improve children's diet quality.

The physical environment in family childcare homes and children's physical activity

BACKGROUND

Family childcare homes (FCCHs) are the second largest provider of childcare in the United States, yet little is known about how this setting influences children's physical activity, particularly related to the physical environment. Thus, the purpose of this study was to determine what aspects of the FCCH physical environment facilitate or hinder children's physical activity.

METHODS

Data were collected from 166 FCCH providers and 496 preschool-aged children in 2013-2014 as part of the Keys to Healthy FCCHs study. Children's moderate-to-vigorous physical activity (MVPA) was measured using Actigraph GT3X+ accelerometers. Wear data from the childcare day were isolated, and cut-points were applied in order to calculate children's minutes of MVPA per hour. FCCH-level estimates of child MVPA per hour were calculated. Indoor and outdoor physical environment characteristics were assessed during a 2-day observation using the Environment and Policy Assessment and Observation modified for FCCHs. General linear models were used to examine the relationship between indoor, portable play equipment, and outdoor FCCH physical environment characteristics and children's MVPA per hour.

RESULTS

Only indoor play space was significantly associated with children's MVPA (β = 0.33; p = .034), indicating that when provided with more indoor space for active play, children were more physically active. No significant associations were noted between portable play equipment or the outdoor environment and children's MVPA.

CONCLUSIONS

Indoor space was the only physical environment characteristic associated with children's MVPA, suggesting that teaching FCCH providers how to best utilize their indoor play space for active play may be a way to promote children's physical activity. Futures studies should explore the impact of other environmental characteristics of the FCCH (e.g., provider practices and policies) on children's physical activity.

Activating Childcare Environments for All Children: the Importance of Children's Individual Needs

Characteristics of the physical childcare environment are associated with children’s sedentary behavior (SB) and physical activity (PA) levels. This study examines whether these associations are moderated by child characteristics. A total of 152 1- to 3-year-old children from 22 Dutch childcare centers participated in the study. Trained research assistants observed the physical childcare environment, using the Environment and Policy Assessment Observation (EPAO) protocol. Child characteristics (age, gender, temperament and weight status) were assessed using parental questionnaires. Child SB and PA was assessed using Actigraph GT3X+ accelerometers. Linear regression analyses including interaction terms were used to examine moderation of associations between the childcare environment and child SB and PA. Natural elements and portable outdoor equipment were associated with less SB and more PA. In addition, older children, boys and heavier children were less sedentary and more active, while more use of childcare and an anxious temperament were associated with more SB. There were various interactions between environmental factors and child characteristics. Specific physical elements (e.g., natural elements) were especially beneficial for vulnerable children (i.e., anxious, overactive, depressive/withdrawn, overweight). The current study shows the importance of the physical childcare environment in lowering SB and promoting PA in very young children in general, and vulnerable children specifically. Moderation by child characteristics shows the urgency of shaping childcare centers that promote PA in all children, increasing equity in PA promotion in childcare.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Interventions to increase consumption of fruit and vegetables, such as those focused on specific child-feeding strategies and parent nutrition education interventions in early childhood may therefore be an effective strategy in reducing this disease burden.

Multicomponent interventions versus no intervention may have a very small effect on child consumption of fruit and vegetables (SMD 0.35, 95% CI 0.04 to 0.66; participants = 2009; studies = 5; low-quality evidence), equivalent to an increase of 0.37 cups of fruit and vegetables per day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.12, 95% CI -0.03 to 0.28; participants = 3078; studies = 11; very low-quality evidence).Insufficient data were available to assess long-term effectiveness, cost effectiveness and unintended adverse consequences of interventions.

The family child care home environment and children's diet quality

BACKGROUND

Developing healthy eating behaviors and food preferences in early childhood may help establish future healthy diets. Large numbers of children spend time in child care, but little research has assessed the nutritional quality of meals and snacks in family child care homes. Therefore, it is important to assess foods and beverages provided, policies related to nutrition and feeding children, and interactions between providers and children during mealtimes. We examined associations between the nutrition environments of family child care homes and children's diet quality.

METHODS

We assessed the nutrition environments of 166 family child care homes using the Environment and Policy Assessment and Observation (EPAO) (scores range: 0-21). We also recorded foods and beverages consumed by 496 children in care and calculated healthy eating index (HEI) (scores range: 0-100). We used a mixed effects linear regression model to examine the association between the EPAO nutrition environment (and EPAO sub-scales) and child HEI, controlling for potential confounders.

RESULTS

Family child care homes had a mean (standard deviation, SD) of 7.2 (3.6) children in care, 74.1% of providers were black or African American, and children had a mean (SD) age of 35.7 (11.4) months. In adjusted multivariable models, higher EPAO nutrition score was associated with increased child HEI score (1.16; 95% CI: 0.34, 1.98; p = 0.006). Higher scores on EPAO sub-scales for foods provided (8.98; 95% CI: 3.94, 14.01; p = 0.0006), nutrition education (5.37; 95% CI: 0.80, 9.94; p = 0.02), and nutrition policy (2.36; 95% CI: 0.23, 4.49; p = 0.03) were all associated with greater child HEI score.

CONCLUSIONS

Foods and beverages served, in addition to nutrition education and nutrition policies in family child care homes, may be promising intervention targets for improving child diet quality.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future chronic diseases, including cardiovascular disease.

OBJECTIVES

To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE and Embase to identify eligible trials on 25 September 2017. We searched Proquest Dissertations and Theses and two clinical trial registers in November 2017. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included studies to identify further potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements.

Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included 55 trials with 154 trial arms and 11,108 participants. Thirty-three trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Thirteen trials examined the impact of parent nutrition education in increasing child fruit and vegetable intake. Eight studies examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. One study examined the effect of a nutrition intervention delivered to children in increasing child fruit and vegetable intake.We judged 14 of the 55 included trials as free from high risks of bias across all domains; performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining studies.Meta-analysis of trials examining child-feeding practices versus no intervention revealed a positive effect on child vegetable consumption (SMD 0.38, 95% confidence interval (CI) 0.15 to 0.61; n = 1509; 11 studies; very low-quality evidence), equivalent to a mean difference of 4.03 g of vegetables. There were no short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.11, 95% CI -0.05 to 0.28; n = 3023; 10 studies; very low-quality evidence) or multicomponent interventions versus no intervention (SMD 0.28, 95% CI -0.06 to 0.63; n = 1861; 4 studies; very low-quality evidence).Insufficient data were available to assess long-term effectiveness, cost effectiveness and unintended adverse consequences of interventions. Studies reported receiving governmental or charitable funds, except for three studies reporting industry funding.

AUTHORS' CONCLUSIONS

Despite identifying 55 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains sparse. There was very low-quality evidence that child-feeding practice interventions are effective in increasing vegetable consumption in children aged five years and younger, however the effect size was very small and long-term follow-up is required. There was very low-quality evidence that parent nutrition education and multicomponent interventions are not effective in increasing fruit and vegetable consumption in children aged five years and younger. All findings should be considered with caution, given most included trials could not be combined in meta-analyses. Given the very low-quality evidence, future research will very likely change estimates and conclusions. Such research should adopt more rigorous methods to advance the field.This is a living systematic review.
