Nutrition and physical activity interventions in preschool & child care

Nutrition and physical activity interventions in preschool and child care offer young children opportunities to eat healthy foods and engage in physical activity throughout the day. Nutrition interventions provide fruits, vegetables, and other healthy foods as part of snacks, meals, taste-testing, and food preparation, frequently with basic nutrition education. Physical activity interventions provide opportunities for children to increase their physical activity, typically by training teachers to incorporate physical activity into daily routines, changing the physical environment, or offering more time for physical activity. Government regulations and organizational policies can support these interventions through guidelines for healthy food consumption, physical activity, and screen time, and support for playground improvements (AAP-Early care standards 2012).

Expected Beneficial Outcomes (Rated)

Evidence of Effectiveness

There is strong evidence that nutrition interventions in preschool and child care improve children’s diets (Mikkelsen 2014, Grantham-McGregor 2014, , Robinson 2014) and physical activity interventions increase their activity levels (, , , Robinson 2014). However, variation in the design, duration, and implementation of these interventions can result in varied effects (, Mehtala 2014) and additional evidence is needed to determine if these interventions reduce risk of overweight or obesity (, , ).

Adhering to nutrition guidelines in preschool and child care can decrease children’s fat intake and increase fruit and vegetable intake (Mikkelsen 2014, ). Implementing physical activity interventions can increase participant’s fitness and motor skills (). In some circumstances, nutrition and physical activity interventions have been shown to reduce children’s weight, body fat, or body mass index (BMI) (Mikkelsen 2014, Bluford 2007, ).

Overall, interventions that increase time for physical activity, provide portable play equipment (e.g., balls and other objects), and include playground markings have been shown to increase moderate to vigorous physical activity (, Broekhuizen 2014, ). Adding portable play equipment has greater effects on physical activity than adding fixed play structures and equipment, since children tend to gather and stand still on or under fixed structures ().

Researchers recommend that child care centers provide teachers with training in how to integrate physical activity into learning to maximize effects on children’s physical activity (, , Mehtala 2014). A culturally sensitive approach is also suggested to increase the effectiveness of obesity prevention efforts such as nutrition and physical activity interventions in preschool and early child care (CDC-Health equity resources, NRC NPAA-Cultural diversity). Culturally sensitive interventions are implemented with a clear understanding of cultural values, generally with the help of bilingual and bicultural facilitators, and often include translated and literacy-appropriate materials, social support, and family-based activities (Mier 2010).

Implementation Examples

The Public Health Law Center’s (PHLC) 50-state review of early childhood care and education regulations includes nutrition and physical activity standards; the on-line map is searchable by state (PHLC-Child care regulations). Terms and standards relating to nutrition, physical activity, and screen time vary widely across the country; however, very few states incorporate their standards into their statewide regulations (ALR-Frost 2015). The National Resource Center for Health and Safety in Child Care and Early Education (NRC) identifies 47 potential components for licensing standards that support healthy dietary behaviors and physical activity for young children (AAP-Early care standards 2012). CDC’s 2013 Prevention Status Reports show that no state has regulations that include more than 70% of those 47 components (CDC-NPAO PSR 2013).

Illinois adopted a resolution in 2012 calling for daily, quality physical education in preschool and early child care centers, among other child obesity prevention measures (NCSL Winterfeld-Obesity prevention 2014). In some states, nutrition and physical activity interventions focus on developing curriculum and training early childhood care and education providers through non-profit and public sector partnerships, as in Idaho (CDHD-IdahoSTARS).
