Association between early care and education centres policies and practices and children's healthy behaviours

To examine the impact of nutritional and physical activity (PA) policies and practices at early care and education centres on behavioural changes among children ages 2-5.The study population included 586 children from 25 education centres throughout the state of Georgia. Policies and practices were measured using the Georgia Nutrition and PA Assessment at the start of school year in Fall 2017. Survey data were collected at the beginning of school year September/October 2017 and at the end of school year April/May 2018 to measure changes in children's nutritional and PA behaviour over the school year. We used generalised estimating equations to estimate odds ratios and 95% confidence intervals.Children at centres with a high nutrition assessment score had higher odds of increasing vegetable consumption (OR = 2.1; 95% CI: 1.1, 4.0) while the odds of increasing fruit (OR = 1.4; 95% CI: 0.8, 2.4) and water (OR = 1.2; 95% CI: 0.5, 2.7) consumption increased non-significantly. The odds of improving PA were similar between children at centres with a high versus a low PA assessment score.The results, though insignificant, indicate that policies and practices could influence children's health behaviours. Further research is warranted to examine whether improvements in policies and practices could explain changes in children's health behaviours, the impact of educator's knowledge on children's health behaviours and the implementation of and adherence to policy and practice improvement plans.
