Long‐term follow‐up of the impact of brief sleep and lifestyle interventions in infancy on BMIz‐score at 11 years of age: The POI randomized controlled trial
Authors' conclusion
Sustained reductions in BMI and obesity risk from an early sleep intervention were not apparent 9 years later, whereas a more traditional lifestyle intervention resulted in increased rates of obesity, not explained by any differences in lifestyle behaviours measured.

As reported in the abstract
