Trial Outcomes & Findings for Infant Environment Study (NCT NCT02936284)

NCT ID: NCT02936284

Last Updated: 2024-09-04

Results Overview

Food reinforcing proportion measures responding for food / total responding for both food and music as a proportion score. Scores range from 0 to 1.0 and higher scores indicate more responding for food than for non-food alternative reinforcer of music. Means reported here are estimated from the mixed-model regression analysis

Population: Intent to treat

Weight for length is a measure of an infant (child under 5-years of age) height (cm) and weight (kg) scored using the World Health Organization (WHO) infant growth chart. Overweight cut-offs at a z-score between 1.0-1.99 and obese cut offs are at a z-score of \>=2.0
