Correlates of children's dietary intake, physical activity and sedentary behavior in home-based childcare: A systematic review
Preventive Medicine Reports
This systematic review assessed the correlates of children's dietary intake, physical activity and sedentary behavior in home-based childcare. A systematic search of five databases with articles published between January 2000 and July 2021 was conducted. Articles were included if they contained data from a home-based childcare (birth-5 years) setting; were a quantitative study that reported children's dietary intake, physical activity or sedentary behavior; included variables associated with children's dietary intake, physical activity or sedentary behavior; and were published in English. Correlates were categorized using McLeroy's social ecological framework. Risk of bias was assessed using the Office of Health Assessment and Translation (OHAT) Risk of Bias Rating Tool. Fifteen studies met the inclusion criteria; six assessed children's dietary intake, and nine assessed physical activity and/or sedentary behaviors. Studies were conducted in the USA (n = 12) and Canada (n = 3). Seventy-three correlates were identified, for children's dietary intake (n = 11), physical activity (n = 35) and sedentary behavior (n = 27). Ethnicity and the food provided to children were associated with children's dietary intake in two studies; both from the same study sample. Indoor play space was positively associated with physical activity in two separate studies. No consistent associations for children's dietary intake, physical activity, or sedentary behavior outcomes were found between studies, however few studies assessed the same correlates. High-quality studies conducted in different countries that assess the nutrition and physical activity environments in home-based childcare using reliable and consistent methods are needed. This review was registered with PROSPERO, no. CRD42019103429.
