ABSTRACT
OBJECTIVE: Report long-term outcomes of the NOURISH randomized controlled trial (RCT), which evaluated a universal intervention commencing in infancy to provide anticipatory guidance to first-time mothers on "protective" complementary feeding practices that were hypothesized to reduce childhood obesity risk. METHODS: The NOURISH RCT enrolled 698 mothers (mean age 30.1 years, SD = 5.3) with healthy term infants (51% female). Mothers were randomly allocated to usual care or to attend two 6-session, 12-week group education modules. Outcomes were assessed 5 times: baseline (infants 4.3 months); 6 months after module 1 (infants 14 months); 6 months after module 2 (infants 2 years) and at 3.5 and 5 years of age. Maternal feeding practices were self-reported using validated questionnaires. BMI Z-score was calculated from measured child height and weight. Linear mixed models evaluated intervention (group) effect across time. RESULTS: Retention at age 5 years was 61%. Across ages 2 to 5 years, intervention mothers reported less frequent use of nonresponsive feeding practices on 6 of 9 scales. At 5 years, they also reported more appropriate responses to food refusal on 7 of 12 items (Ps ≤ .05). No statistically significant group effect was noted for anthropometric outcomes (BMI Z-score: P = .06) or the prevalence of overweight/obesity (control 13.3% vs intervention 11.4%, P = .66). CONCLUSIONS: Anticipatory guidance on complementary feeding resulted in first-time mothers reporting increased use of protective feeding practices. These intervention effects were sustained up to 5 years of age and were paralleled by a nonsignificant trend for lower child BMI Z-scores at all postintervention assessment points.

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.

OBJECTIVE: The goal of this study was to evaluate outcomes of a universal intervention to promote protective feeding practices that commenced in infancy and aimed to prevent childhood obesity. METHODS: The NOURISH randomized controlled trial enrolled 698 first-time mothers (mean ± SD age: 30.1 ± 5.3 years) with healthy term infants (51% female) aged 4.3 ± 1.0 months at baseline. Mothers were randomly allocated to self-directed access to usual care or to attend two 6-session interactive group education modules that provided anticipatory guidance on early feeding practices. Outcomes were assessed 6 months after completion of the second information module, 20 months from baseline and when the children were 2 years old. Maternal feeding practices were self-reported by using validated questionnaires and study-developed items. Study-measured child height and weight were used to calculate BMI z scores. RESULTS: Retention at follow-up was 78%. Mothers in the intervention group reported using responsive feeding more frequently on 6 of 9 subscales and 8 of 8 items (all, P ≤ .03) and overall less controlling feeding practices (P < .001). They also more frequently used feeding practices (3 of 4 items; all, P < .01) likely to enhance food acceptance. No statistically significant differences were noted in anthropometric outcomes (BMI z score: P = .10) nor in prevalence of overweight/obesity (control 17.9% vs intervention 13.8%; P = .23). CONCLUSIONS: Evaluation of NOURISH data at child age 2 years found that anticipatory guidance on complementary feeding, tailored to developmental stage, increased use by first-time mothers of "protective" feeding practices that potentially support the development of healthy eating and growth patterns in young children.
