Nutrition and Physical Activity in Child Care. Results from an Environmental Intervention

BACKGROUND With evidence of increased levels of obesity in younger children, the child-care setting is an important intervention target. Few environmental interventions exist, and none target both diet and physical activity. The Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) intervention was developed to fill this research and practice gap. DESIGN Randomized controlled. SETTING/PARTICIPANTS Health professionals (child-care health consultants) serving child-care centers in North Carolina were recruited (n=30), randomly assigned into intervention or delayed-intervention control groups, and trained to implement the NAP SACC program. Up to three child-care centers were recruited (n=84) from each consultants existing caseload. INTERVENTION Implemented in 2005, the NAP SACC intervention includes an environmental self-assessment, selection of areas for change, continuing education workshops, targeted technical assistance, and re-evaluation. Implementation occurred over a 6-month period. MAIN OUTCOME MEASURES An observational instrument, Environment and Policy Assessment and Observation (EPAO), provided objective evidence of intervention impact and was completed by trained research staff blinded to study assignment. Data were collected in 2005 and 2006. Statistical analyses were conducted in 2006. RESULTS Intention-to-treat analysis results were nonsignificant. Exploratory analyses using only centers that completed most of the NAP SACC program suggest an intervention effect. CONCLUSIONS Factors in the intervention design, the fidelity of implementation, the selection of outcome measure, or a combination of these may have contributed to the lack of intervention effect observed. Because of this studys use of existing public health infrastructure and its potential for implementation, future studies should address strategies for improving effectiveness.

An instrument to assess the obesogenic environment of child care centers.

OBJECTIVES To describe protocol and interobserver agreements of an instrument to evaluate nutrition and physical activity environments at child care. METHODS Interobserver data were collected from 9 child care centers, through direct observation and document review (17 observer pairs). RESULTS Mean agreement between observer pairs was 87.26% and 79.29% for the observation and document review, respectively. Items with lower agreement were primarily staff behavior, counting across the day/week, and policy classifications. CONCLUSIONS Although some revisions are required, the interobserver agreement for the environment and policy assessment and observation (EPAO instrument) appears to be quite good for assessing the nutrition and physical activity environment of child care centers.

Dietary Intakes in North Carolina Child-Care Centers: Are Children Meeting Current Recommendations?

The purpose of this study was to determine whether food consumed by children while in center-based child care meets the new MyPyramid food group recommendations for children 2 to 5 years of age. Dietary observation of 117 children from 20 child-care centers throughout North Carolina was conducted. The type and amount of food served to and consumed by children was observed and assessed using Nutrition Data System for Research (NDS-R) software (version 2005, Nutrition Coordinating Center, University of Minnesota, Minneapolis). Portion sizes were then compared to the new MyPyramid food group recommendations to see whether 1/2 to 2/3 (for time spent in full-day child care) of the recommended amounts were consumed. On average, of the five main food groups, children consumed only the 1/2 to 2/3 recommendation for milk. Children also consumed less than 13% of MyPyramid recommendations for whole grains and 7% of MyPyramid recommendations for dark vegetables. Also noteworthy, 50% of milk consumed was whole milk and 75% of the meat consumed was of the high-fat or fried variety. Overall, our data suggest that children are not consuming recommended amounts of whole grains, fruits (excluding 100% fruit juice), or vegetables while attending full-time child care, and are consuming excess amounts of saturated fat and added sugar.

Best-Practice Guidelines for Physical Activity at Child Care

Research has indicated that the child care center is a very strong predictor of preschool-aged childrens physical activity levels, making this an important setting to help young children obtain physical activity that is appropriate for their health and development. However, some evidence suggests that organized child care may not adequately support childrens physical activity needs. Although many organizations provide recommendations, guidelines, or standards for motor skill development and physical activity opportunities, no set of guidelines exist that directly target the overall physical activity environment at child care. Because of the lack of comprehensive recommendations, the Nutrition and Physical Activity Self-assessment for Child Care best-practice guidelines for healthy weight development were created on the basis of an extensive review of existing guidelines, research evidence, and expert review. The purpose of this article is to present these physical activity best-practice guidelines and provide data on how these guidelines compare to current practice in a large sample (N = 96) of child care centers in North Carolina. These best-practice guidelines include recommendations for 8 unique components of the child care environment, including active opportunities, fixed play environment, portable play environment, sedentary opportunities, sedentary environment, staff behavior, staff training/education, and physical activity policies. Our results showed that only a few of the best-practice guidelines were achieved by a majority of the 96 North Carolina child care centers that participated in this study. Establishing comprehensive guidelines for physical activity at child care could result in higher activity levels and healthier children, but more research is needed.

Reliability and validity of a nutrition and physical activity environmental self-assessment for child care

BackgroundFew assessment instruments have examined the nutrition and physical activity environments in child care, and none are self-administered. Given the emerging focus on child care settings as a target for intervention, a valid and reliable measure of the nutrition and physical activity environment is needed.MethodsTo measure inter-rater reliability, 59 child care center directors and 109 staff completed the self-assessment concurrently, but independently. Three weeks later, a repeat self-assessment was completed by a sub-sample of 38 directors to assess test-retest reliability. To assess criterion validity, a researcher-administered environmental assessment was conducted at 69 centers and was compared to a self-assessment completed by the director. A weighted kappa test statistic and percent agreement were calculated to assess agreement for each question on the self-assessment.ResultsFor inter-rater reliability, kappa statistics ranged from 0.20 to 1.00 across all questions. Test-retest reliability of the self-assessment yielded kappa statistics that ranged from 0.07 to 1.00. The inter-quartile kappa statistic ranges for inter-rater and test-retest reliability were 0.45 to 0.63 and 0.27 to 0.45, respectively. When percent agreement was calculated, questions ranged from 52.6% to 100% for inter-rater reliability and 34.3% to 100% for test-retest reliability. Kappa statistics for validity ranged from -0.01 to 0.79, with an inter-quartile range of 0.08 to 0.34. Percent agreement for validity ranged from 12.9% to 93.7%.ConclusionThis study provides estimates of criterion validity, inter-rater reliability and test-retest reliability for an environmental nutrition and physical activity self-assessment instrument for child care. Results indicate that the self-assessment is a stable and reasonably accurate instrument for use with child care interventions. We therefore recommend the Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) instrument to researchers and practitioners interested in conducting healthy weight intervention in child care. However, a more robust, less subjective measure would be more appropriate for researchers seeking an outcome measure to assess intervention impact.

Comparison of Menus to Actual Foods and Beverages Served in North Carolina Child-Care Centers

Menus from child-care centers are an important source of information for parents, researchers, and child-care regulators, but previous research suggests that menus do not accurately represent foods served. The purpose of this study was to compare menus with actual foods and beverages served to children in child-care centers. Menus were collected and a dietary observation was conducted to document all foods and beverages served to children during the course of 1 day in 84 child-care centers in North Carolina in the fall of 2005. Frequencies of foods and beverages on the menus vs those served were computed by eating occasion, food category, and individual foods and beverages. Of the 254 meals and snacks served, 131 (52%) meals and snacks matched entirely what was stated on the menu. Of the 820 individual foods and beverages served, 710 (86.6%) matched those listed on the menus. An additional 110 foods and beverages were served but not listed on the menus. Grains, juice, and vegetables were served less often than indicated on the menus, and milk, protein-rich foods, fruits, mixed dishes, and foods of low nutritional value were served more often than listed on the menus. Overall, just over half of all meals and snacks matched menus, and nearly 90% of individual foods and beverages served matched those stated on menus. Parents of children in child care and dietetics practitioners providing consultation to child-care centers can encourage not only provision of healthy foods and beverages, but also accurate menus in child care.

Improving Nutrition and Physical Activity in Child Care: What Parents Recommend

A large percentage of children in the United States spend part of their day in out-of-home child care. As rates of obesity continue to rise, especially among young children, child care has become a focus for nutrition and physical activity intervention. Parental involvement is an important component of these efforts. During summer 2006, parents of children in child care were surveyed to better understand their perceived quality of meals, snacks, and physical activity at the child-care center, and their recommendations for improvement. Parents of children who attended 94 licensed child-care centers in North Carolina were invited to complete a brief survey of perceived quality of meals, snacks, and physical activity at their centers using close-ended questions. Open-ended questions were used to identify suggestions for improvement. Five hundred eight parents from 91 child-care centers completed the questionnaire. The majority of parents reported quality of meals and snacks at the center as either excellent (30% meals, 27% snacks) or good (42% meals, 46% snacks). The main recommendations for improving meals and snacks were to increase fruits and vegetables and provide a variety of healthful foods. The majority of parents categorized the quality of physical activity at the center as excellent (36%) or good (46%), and suggested more structured, outdoor activities for children. Findings from this study provide insight into key areas of concern for parents regarding the nutrition and activity environment of child-care centers. This information may be used to create or modify interventions or policies and to help motivate parents to become advocates for change in child care.

Nutrition practices and mealtime environments of North Carolina child care centers.

BACKGROUND The majority of children in the United States attend out-of-home child care. However, little is known about the nutritional quality of foods served and the mealtime environments. METHODS We assessed 96 child care centers over one full day using a researcher-administered structured observation and document review. We focused on eight nutrition domains: (1) fruits and vegetables, (2) whole grains, (3) high-sugar, high-salt, and high-fat foods, (4) beverages, (5) food availability and service, (6) staff behaviors, (7) training and education, and (8) policies. We computed daily means and frequencies for each domain. RESULTS Seventy-five percent of centers participated in the Child and Adult Care Food Program, indicating they served low-income children. Centers enrolled 66 children on average; 60% were white, 28% were black, 4% were Native American, and 8% identified as mixed race. On the day of observation, seven centers did not serve a fruit and 15 did not serve a vegetable. Eighty centers served a high-sugar or high-salt food and 84 did not serve any whole grains. Five centers did not provide water indoors to children, 22 served juice twice, and 50 served whole milk. Seventeen centers had a vending machine on site visible to parents and children. Overall, children were served excessive juice, high-sugar and high-salt snack foods, and too much whole milk. CONCLUSIONS Centers had room for improvement and could strive to serve more nutritious foods and create healthier mealtime environments for children.
