OBJECTIVE: Short sleep duration may contribute to childhood obesity. Amenable to intervention, sleep thus provides a potential path for prevention. The authors aimed to determine the impact of a behavioural intervention that successfully reduced parent-reported infant sleep problems on adiposity at age 6. DESIGN: 5-year follow-up of a previously reported population-based cluster randomised trial. Participant allocation was concealed to researchers and data collection blinded. SETTING: Recruitment from well-child centres in Melbourne, Australia. PARTICIPANTS: 328 children (174 intervention) with parent-reported sleep problems at age 7-8 months drawn from 49 centres (clusters). INTERVENTION: Behavioural sleep strategies delivered over one to three structured individual nurse consultations from 8 to 10 months, versus usual care. MAIN OUTCOMES AT AGE 6 YEARS: Body mass index (BMI) z-score, percentage overweight/obese and waist circumference. ANALYSES: Intention-to-treat regression analyses adjusted for potential confounders. RESULTS: Anthropometric data were available for 193 children (59% retention) at age 6. There was no evidence of a difference between intervention (N=101) and control (N=92) children for BMI z-score (adjusted mean difference 0.2, 95% CI -0.1 to 0.4), overweight/obese status (20% vs 17%; adjusted OR 1.4, 95% CI 0.7 to 2.8) and waist circumference (adjusted mean difference -0.3, 95% CI -1.6 to 1.1). In posthoc analyses, neither infant nor childhood sleep duration were associated with anthropometric outcomes. CONCLUSIONS: A brief infant sleep intervention did not reduce overweight/obesity at 6 years. Population-based primary care sleep services seem unlikely to reduce the early childhood obesity epidemic.
