Children consume up to two-thirds of their daily dietary requirements in full-time childcare, making the setting a critical vector for preventing childhood obesity. Objective: To summarize the ecological correlates of children’s dietary intake in childcare settings that were identified and categorized using the Six-Cs developmental ecological model of contributors to overweight and obesity in childhood. Data Sources: A literature search was conducted in 4 electronic databases. Study Selection: English-language, peer-reviewed publications that investigated at least 1 correlate of children’s (ages 2–6 years) dietary intake in childcare settings and measured children’s actual consumption of foods and beverages from food groups were included.
