Effectiveness of an Early Intervention on Infant Feeding Practices and “Tummy Time”

OBJECTIVE: To assess the effectiveness of a home-based early intervention on infant feeding practices and "tummy time" for infants in the first year of life. DESIGN: Randomized controlled trial with follow-up measures scheduled at 6 and 12 months. SETTING: Socially and economically disadvantaged areas of Sydney, Australia. PARTICIPANTS: We recruited 667 first-time mothers and their infants in 2007 and 2008. INTERVENTIONS: The intervention consisted of 5 or 6 home visits from a specially trained research nurse delivering a staged home-based intervention in the antenatal period and at 1, 3, 5, 9, and 12 months. MAIN OUTCOME MEASURE: Changes in infant feeding practices and "tummy time." RESULTS: The intervention group had a significantly higher median duration of breastfeeding at 12 months than the control group (17 weeks 95% confidence interval, 13.9-20.4 weeks vs 13 weeks 95% confidence interval, 10.1-15.0 weeks; P = .03). Compared with the control group, the hazard ratio for stopping breastfeeding in the intervention group was 0.82 (95% confidence interval, 0.68-0.99). The intervention also resulted in a significantly later introduction of solid foods (P < .001 for trend), reducing the proportion of mothers who introduced solids before 6 months by 12% (95% confidence interval, 4%-20%) from 74% to 62%. The intervention also decreased the age at which infants started tummy time (P = .03 for trend) and increased the daily practice of tummy time by 7% from 76% to 83% (P = .05). CONCLUSION: The home-based early intervention delivered by trained community nurses significantly improved some infant feeding practices and resulted in earlier daily practice of tummy time.
