Percentages and standard errors are based on mixed-effects models of the treatment-by-time interaction that adjusted for repeated measures within families and nesting of families within ECE centers. The models were based on data from 4712 lunches packed by parents for their preschool children. Each model compared the given measurement period to baseline. The models also were adjusted for gender, age, heritage, parental marital status and parental education. Percent of parents packing the given foods was based on the occurrence of any amount of the food on at least one of the two days in the measurement period
