Objective The objective was to describe parent-reported child eating behavior and maternal parenting impact outcomes of an infant feeding intervention to reduce child obesity risk. Methods An assessor masked Randomized Controlled Trial (RCT) with concealed allocation of individual mother-infant dyads. The NOURISH RCT enrolled 698 first-time mothers (mean age 30.1 years, SD = 5.3) with healthy term infants (51% female) aged 4.3 months (SD = 1.0) at baseline. Outcomes were assessed 6 months post-intervention when the children were 2 years old. Mothers reported on child eating behaviors using the Children's Eating Behavior Questionnaire (CEBQ), food preferences, and dietary intake using a 24-hour telephone recall. Parenting was assessed using five scales validated for use in Australia. Results Intervention effects were evident on the CEBQ overall (MANOVA P = 0.002) and 4/8 subscales: child satiety responsiveness (P = 0.03), fussiness (P = 0.01), emotional overeating (P < 0.01), and food responsiveness (P = 0.06). Intervention children "liked" more fruits (P < 0.01) and fewer non-core foods and beverages (P = 0.06, 0.03). The intervention mothers reported greater "autonomy encouragement" (P = 0.002). Conclusions Anticipatory guidance on protective feeding practices appears to have modest positive impacts on child eating behaviors that are postulated to reduce future obesity risk.
