Statistical Analyses

Analyses were performed using SPSS (IBM Corp. Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY). Unadjusted associations between each of the maternal and infant characteristics (sociodemographic factors, maternal depressive symptoms, concerns about future infant weight, and perceived difficult infant temperament) and adding cereal into the bottle were analyzed using Fisher’s exact tests for comparisons with dichotomous variables and chi-square for comparisons with variables with more than two categories. Adjusted associations were analyzed using a simultaneous multiple logistic regression model, in which all maternal and infant characteristics that had been associated with cereal in the bottle with p<.05 in unadjusted analyses were included.
