Prevalence of overweight and obesity in British children: cohort study

Abstract
Subjects consisted of a birth cohort randomly selected from a larger geographically defined total population cohort born in the Bristol-Avon area in 1991-2. The cohort has been described elsewhere2 and is broadly representative of children in the United Kingdom. Height (to 0.1 cm, measured with a Leicester height meter) and weight in underwear (to 0.1 kg, measured with Seca scales) were measured in children at 24, 49 and 61 months of age.
