A double-blind, randomized trial of the efficacy of replacing sugary drinks by low-sugar alternatives on body weight and fat mass in school children. (WC2008-023)

Background

Starting date: 01/01/2008
Liquid carbohydrates are thought to be less satiating than solid carbohydrates, and calories from sugary drinks might not be compensated for by eating less at subsequent meals. Sugary drinks –including soft drinks as well as fruit juices - are therefore thought to be one of the causes of overweight and obesity in children. However government policies to reduce intake have been less than firm. One reason may be that the evidence for an effect of sugary drinks on body weight rests mostly on observational epidemiological studies and a few short term interventions. The observational studies may suffer from confounding by diet and lifestyle and the trials were too short and too small to be convincing.
Therefore,we propose the first long-term, double-blind, randomized, controlled trial of the effect of replacing beverages with sugar by low-sugar alternatives on body weight and fat mass in children aged 5-10 years.
