Abstract
Background:
The amount of time children spend in child care each week has increased in recent years. The aim of this cross-sectional study was to describe the nutritional quality of foods served and the mealtime environment in 24 child care centers in Georgia.
Methods:
Data were collected between April 2010 and September 2010. Each child care center provided a sample 5-day menu (breakfast, lunch, and an afternoon snack) at baseline. Energy and nutrient contents of the menus were analyzed using NutriKids Menu Planning & Nutritional Analysis software (LunchByte Systems, Inc., Rochester, NY). Foods and beverages on the menus were compared to MyPlate food group standards for preschoolers. The child care environment was assessed in each center over 1 full day using the Environment and Policy Assessment and Observation instrument.
Results:
Menus met one half to two thirds of the recommended levels for energy, carbohydrate, protein, and vitamins A and C. However, the menus were high in saturated fat and sodium content and did not meet the recommendations for iron or fiber. The majority of the centers did not meet the recommendations for MyPlate food group standards for preschoolers. On the day of the observation, seven centers did not serve a vegetable and more than half of the centers (n=13) did not serve any whole grains. Nineteen centers served high-sugar and/or high-fat foods and 11 did not have visible water indoors.
Conclusions:
This study identified determinants of the child care environment and nutritional characteristics of the combined meals and snacks offered to children. Findings from this study could inform child care centers how to provide healthier nutrition environments to preschool children.
Introduction
This increase in overweight and obesity in preschoolers is paralleled by a concurrent increase in the use of child care facilities in the United States. Approximately 60% of preschool-aged children with employed mothers are in some form of nonparental care on a regular basis. 5 Children consume a large proportion of their daily energy intake at child care facilities. The Academy of Nutrition and Dietetics recommends that children consume at least one third of their daily nutrition requirements at part-time child care programs (4–7 hours per day) and at least one half to two thirds of their daily nutrition requirements at full-time child care programs (i.e., 8 hours or more). 6 Child care centers that serve low-income families may qualify to participate in the USDA Child and Adult Care Food Program (CACFP) and receive reimbursement for meals and snacks served. 7 Currently, this federal program requires centers to include components from the milk, fruit, vegetable, grain or bread, and meat or meat alternate food groups on their menus, but does not require meals and snacks to meet nutrient-based standards. 8 To ensure that the meals and snacks provided by CACFP are consistent with national nutrition guidance, the USDA asked the Institute of Medicine (IOM) to review and recommend improvements, as necessary, to bring CACFP meal requirements into alignment with those of other federally funded food assistance programs and with the 2010 Dietary Guidelines for Americans.9,10 According to the IOM, the recommended meal requirements will likely increase children's and adults' consumption of fruits, vegetables, whole-grain–rich foods, and lean meats while decreasing their intake of solid fats, trans fats, added sugars, and sodium. 10
Previous studies have assessed the nutritional quality of foods and beverages served to children in child care11–19 ; however, few studies exist on mealtime environment and center policies, including monitoring and training staff.17–21 The aim of this study was to assess, at baseline, the foods and beverages listed on the menus and describe the nutrition practices and mealtime environments in child care centers in southwest Georgia.
Methods
Study Design
This study is part of the Caregivers Promoting Healthy Habits project, a 1-year wellness policy implementation program in 24 child care centers in southwest Georgia.22,23 The objectives of the project are to (1) introduce child care providers to the concept and benefits of wellness policy, (2) help child care providers develop and implement wellness policy in their child care centers, (3) support child care centers through training, technical assistance, and funding, and (4) evaluate the effect of a wellness policy on children and staff in a child care environment.
Centers were provided with technical assistance by a registered dietitian and up to $2000 to support implementation. Center directors and staff participated in four trainings on nutrition and physical activity, menu planning, food safety, and healthy habits consistent with the wellness policies. Trainings were conducted in group settings where participants could exchange ideas with other child care center staff.
Setting and Participants
The southwest region of Georgia was selected for program implementation based on many of the counties' low rankings on a number of health status indicators, including child poverty, adult obesity, and high school graduation rate. In winter 2010, the Georgia Department of Early Care and Learning issued an abbreviated request for applications (RFAs) to centers, held a preapplication conference to introduce centers to the program, and distributed previously developed nutrition and physical activity materials and curricula. Interested centers were asked to respond to RFAs by submitting a self-assessment to help identify areas related to nutrition and physical activity that needed improvement, six selected wellness policies, and proposed activities related to implementation of policies. At baseline, 24 child care centers applied and were enrolled in the program.
Participation criteria for the program included that centers were licensed by the state and were not considered a child care or Pre-K program in an elementary school. All centers were required to be enrolled in the CACFP. 7 For-profit (n=14) and nonprofit (n=10) centers were included in the program, with four centers offering the Head Start program and only one accredited by the National Association for the Education of Young Children. All centers provided full-day programs.
Baseline data were collected between April 2010 and September 2010. The Georgia State University Institutional Review Board approved all study procedures and activities. All participants (child care centers' directors) provided written informed consent.
Assessment of Nutrition Environment and Practices
Assessment of child care centers' menus
All centers provided two meals and one snack each day to participating children while at the child care centers. Centers were asked to provide their 5-day menu during the initial visit, because it is a required document as part of the Environment and Policy Assessment and Observation instrument (EPAO; described later). A registered dietitian coded and standardized all the menu items. NutriKids Menu Planning & Nutritional Analysis software (Version 11.1, 2009; LunchByte Systems Inc., Rochester, NY) was used for menu analysis. Food service providers were asked for clarification regarding specific types of different foods when they were not listed on the menu (e.g., type of milk). Food items described in the menus were matched with the most appropriate food item in the database (e.g., the “assorted cereal” choice on NutriKids was matched for “cereal” on the menu). Information on portion sizes was also entered for every menu item. The centers were using the portion sizes required in the CACFP program for the meal pattern components for children 3–5 years of age. 8 For quality control, each menu entered was compared with the submitted menu for errors.
Energy and nutrient contents of 120 menus across the 24 centers were analyzed quantitatively for energy and 11 main nutrients (carbohydrate, protein, total fat, saturated fat, cholesterol, fiber, sodium, calcium, iron, and vitamins A and C) based on the 2011 Position of the Academy of Nutrition and Dietetics 6 and the 2010 Dietary Guidelines for Americans. 9 Energy and nutrient content for breakfast, lunch, and snacks served each day were summed and averaged over the 5 days for each participating center. The mean and standard deviation (SD) of the 5-day mean nutrients were then calculated for the 24 participating centers.
The menus were also analyzed qualitatively using a menu rubric developed by the researchers and a registered dietitian. The rubric evaluated the frequency of food items listed on the menus from the different food groups from MyPlate for preschoolers 24 : whole grains; vegetables; fruits; meats and meat alternatives; milk and milk alternatives; high-fat or high-sugar foods; and sugar-sweetened or artificially sweetened beverages. A registered dietitian filled the rubric based on the 5-day menus provided by the participating centers.
Observation of the nutrition environment
The child care environment was assessed using the EPAO. The EPAO has been shown to be a “reliable” tool for assessing nutrition and physical activity environments in child care centers.25,26 The EPAO protocol consists of one full-day visit to each child care center and includes direct observation of the nutrition and physical environment and documented review of activities. Observations in 24 child care centers took place between May 2010 and September 2010. Center visits were unannounced, and observations were performed by one registered dietitian who completed training to conduct the EPAO. During the observation day, all activities of a randomly selected classroom of 3- to 5-year-old children were observed during breakfast, lunch, and afternoon snack. In some cases, the registered dietitian asked child care providers for clarification or additional information. The document review involves an evaluation of the teacher's lesson plan for that week, past or future fund-raising documents, menus for up to 1 month that include the week of the visit, parent handbook, staff handbook, nutrition training documents, nutrition curricula, and written nutrition policies. 17 Observations began at breakfast and lasted until the conclusion of the child care program. For the purpose of this study, the domains related to the nutrition section of the EPAO were assessed: fruits and vegetables; whole grains; foods high in sugar or fat; beverages; food availability and service; staff behaviors; training and education; and policies.25,26
Statistical Analysis
Descriptive statistics for energy, macronutrients, and micronutrients were determined. For the menu analysis, mean calorie and nutrient contents of the menus were compared against one half and two thirds of the IOM's Dietary Reference Intakes (DRI) for 3- to 5-year-old children 27 to determine the number (and percentage) of centers meeting recommendations. All statistical analyses were done using Statistical Package for the Social Sciences (version 18, 2010; PASW Statistics, Chicago, IL).
Results
Centers' Characteristics
A total of 24 child care centers serving a total of 2042 children participated in the study (mean number of children, 85; range, 20–245). All centers participated in the CACFP. Twenty-two centers had a kitchen in the same building as the classrooms for food preparation. The two centers that did not have an on-site kitchen received cooked food from the local hospital. Seventy percent of the centers (n=17) reported the cook as the person responsible for menu planning. The director of the center (n=5) and staff members (n=2) were also reported as the menu planner. Only 25% of the centers (n=6) reported consulting a dietitian for menu planning.
Nutrient and Food Group Content of Menus
A sample of 120 menus across the 24 participating centers was analyzed for energy and nutrient contents. When compared to the DRIs for the 3- to 5-year-old children, 24 it was found that the menus provided one half to two thirds of the DRI for energy, carbohydrate, protein, and vitamins A and C (Table 1). However, the menus were high in saturated fat and sodium. The average menus usually provided one half of the daily requirements for calcium and iron, but fell short of the two-thirds recommendation for iron in 10 centers. Additionally, the menus were low in fiber; none of the centers met one half or two thirds of the recommendations for fiber content (Table 1).

All the centers listed milk on their menus on a daily basis; however, 71% of the centers listed whole or 2% milk and only 29% of the centers (n=7) listed the recommended 1% or skim milk. Most centers (92%) had fried or high-fat proteins one to two times/week on the menu (Table 2). Vegetables, not including fried vegetables, were listed on the menu daily in only seven centers (29%). All centers listed fruits on a daily basis (Table 2). All centers listed a sweet snack on the menu (e.g., cookies, donut, pastries, cookies, or muffins), and 71% a high-sugar or high-fat condiment (e.g., butter, dressing, syrup, or jelly; Table 2).

Nutrition Practices and Mealtime Environments
On the day of the observation, lunch was served family style (children serve themselves from common bowls and platters) in one third of the centers (n=9), delivered in bulk and proportioned by staff in seven centers (29%), and delivered and served in prepared portions in eight centers (33%). In most of the centers (n=22), all foods served on the day of the observation matched what was on the menu.
Foods and beverages served on the day of observation
Seventeen of twenty-four centers served a vegetable on the day of the observation, but rarely were these servings dark green, red, orange, or yellow vegetables (Table 3). More than half of the centers (n=13) did not serve any whole grains. Only 13 centers did not serve any meats naturally high in fat (e.g., bacon or sausage), and the majority of the centers (80%) served high-sugar and/or high-fat foods. Drinking water was not visible indoors in 11 centers and not available outdoors in 16 (Table 3). Fruit juice (100% juice) was served one time per day in 14 centers and two times per day in three centers. All centers avoided sugar-sweetened beverages during the day of observation (Table 3).

Staff behaviors
In half of the centers (n=13), staff ate together with the children, and in only four centers, staff ate and/or drank less healthy food in front of the children (Table 3). In three centers, children were encouraged to eat more than they wanted to (e.g. “clean your plate” and “you won't get dessert until you finish”) for an average of two eating occasions (data not shown). In only one center, staff asked children whether they were still hungry before serving second helpings and staff used food to control behavior (Table 3).
Training and education
Half of the centers had a nutrition curriculum for children, but its use in the classroom was not evaluated in this study (Table 3). We observed informal nutrition education for children (e.g., staff talking with children about healthy foods) in most centers (n=17) for an average of two eating occasions.
Policies
All centers had a written policy on nutrition and food services. Sixteen centers (67%) had a written policy that addressed foods served during holidays and celebrations, and 17 had a written policy addressing food bought from home (Table 3).
Discussion
Analysis of the combined menus from the participating child care centers shows that the menus met the recommended levels for energy, carbohydrate, protein, and vitamins A and C. However, the percent of energy from saturated fat (12%) exceeds the 10% recommendation, findings similar to those reported by Oakley and colleagues 13 and Bollella and colleagues. 28 The high sodium content of the menus is of concern, and this may be a result of the frequent use of commercially prepared food items (e.g., chicken nuggets and fish sticks) and canned vegetables. Another concern is that the menus served at participating centers failed to meet one half or two thirds of requirements for fiber. Additionally, the menus fell short on iron, which is a key nutrient essential for normal growth and development. Our findings are consistent with other research in child care centers that has demonstrated that the meals served for children were below the recommendations for fiber and iron.11,12,29
Findings from the menu analyses were supported by the observation of the foods and beverages offered during the 1-day visit to the centers. Our data suggest that the meals offered at participating centers do not include the recommended amounts of whole grains, lean proteins, and fresh fruits or vegetables. Findings from this study are consistent with a recent study assessing nutrition practices and mealtime environment of North Carolina child care centers. 21 Children are being offered excessive amounts of added sugars from sweet snacks, sodium, and saturated fat from whole milk and high-fat or fried meats. The 2010 Dietary Guidelines stress the importance of consuming fat-free and low-fat milk and milk products, especially during childhood and adolescence. 9 Although children were offered adequate amounts of milk, 71% of the centers served whole or 2% milk and only 29% of the centers (n=7) served the recommended 1% or skim milk. Our findings are consistent with others that found that most children in child care drink full-fat milk.12,19,21 White bread and ready-to-eat cereal, food sources that are often fortified with vitamins and minerals, were among the most frequently reported foods on the menus. Currently, no nutrition standards exist for the type of cereals allowed in child care meals. Requirements related to the whole-grain content of cereals may help centers substitute current cereal offerings with ones that may increase children's daily intake of whole grains. Although child care meals have frequent offerings of fruits and vegetables, improvements can be made to the type and variety of fruits and vegetables offered.14,21 For example, very few daily menus provided colorful fresh fruits, and menus were more likely to include starchy vegetables (potatoes, corn, and peas) than dark green and orange vegetables.
There is an increasing body of work on the quality of meals and snacks served to children in the CACFP.13,30 Because of the nonspecific nutrition guidelines set by the CACFP, it is possible for child care centers to be in compliance with all regulations without necessarily serving children appropriate food to meet their energy and nutrient requirements. Our findings were similar to the results of the study by Oakley and colleagues 13 ; centers participating in CACFP had menus lower in energy, carbohydrate, and protein and some micronutrients and higher in fat and sodium, compared to nonparticipating centers. 13 A major goal of future research identified in the CACFP report 10 is to assess the food and nutrient content of meals and snacks served to, and consumed by, children and the effect of these meals and snacks on children's overall diets. Policy makers should utilize evidence from this study to support CACFP program revision, in addition to local standards in Georgia.
Beyond the foods and beverages listed on the menus, this study also assessed nutrition practices and mealtime environments at the day care centers. Child care providers could improve their interactions with children by sitting with them during mealtime. This situation enables adults to teach, serve as role models, and initiate socialization skills among children. Additionally, few centers served meals family style, although serving themselves allows children the experience of learning a self-help skill, as well as some measure of control over the type and amount of food on their plates. 31 Centers had also room for improvement in regard to staff's nutrition education and training. Although limited, there is evidence linking training and education to improved health outcomes in child care. 32 In addition, centers could provide more formal, informative nutrition education to children and parents.
To our knowledge, this is the first study to assess nutritional characteristics of the combined meals and snacks offered to children and other aspects of the nutrition environment in a sample of child care centers in Georgia. This study provides timely information because it follows the release of a 2010 report from the IOM on nutrition recommendations for the CACFP 10 and a 2011 Academy of Nutrition and Dietetics updated position paper on benchmarks for nutrition in child care settings. 6 This study contributes to the growing body of literature examining nutrition environments of child care centers, including staff behaviors during meal and snack time. Four previous studies have examined child care provider behaviors and found similar results17–19,21; however, only two examined center environments through direct observation,19,21 rather than self-report by survey.17,18 This study, however, is not without limitations, and results should be interpreted with some caution. This study was limited to child care centers in rural areas and small cities, and this may not reflect the situation in other child care centers or in other urban locations. In addition, we chose only one classroom for observation, and, although no data exist stating that children are differentially served by classroom, future studies may want to assess multiple classrooms per facility. This study relied on menus to assess dietary intake in child care and might not accurately reflect the quantity of food consumed by children. However, a study by Ball and colleagues found that children consumed 50–100% of the foods and beverages served to them in child care centers. 12 Additionally, we analyzed the nutrient composition of foods and beverages listed on the menu, not what was actually served to children. Previous studies have shown that menus are somewhat accurate, when comparing them to actual foods and beverages served to children, and might provide some information on categories of food (e.g., fruits and vegetables) actually served in child care.14,33 Results regarding specific nutrient information, such as vitamins and minerals, should be interpreted with caution when based on menu analysis. Finally, we made a number of assumptions regarding the specific foods and methods of preparation on the menus, and the Nutrition Data System for Research software, the gold standard for dietary analysis, was not used for nutrient analysis.
Conclusions
Overall, this and other studies lend evidence to the need for improving the nutritional quality of foods served to children as well as enhancing the overall mealtime and feeding environments to support healthy eating for preschool children. This study also speaks to the need for more nutrition education of child care staff and increased nutrition intervention in child care. Child care center menu planners need resources and support in providing healthier foods for children. Child care providers can share their menus with parents, as a medium of nutrition communication, which can help create healthier environments for preschool children.
