title: Prevalence and trends in overweight and obesity in three cross sectional studies of British Children, 1974-94.
abstract: OBJECTIVE
  To report trends in overweight and obesity, defined by new internationally agreed cut-off points, in children in the United Kingdom.
  
  
  METHODS
  Three independent cross sectional surveys.
  
  
  METHODS
  Primary schools in England and Scotland.
  
  
  METHODS
  10 414 boys and 9737 girls in England and 5385 boys and 5219 girls in Scotland aged 4 to 11 years.
  
  
  METHODS
  Prevalence and change in prevalence of overweight and obesity, as defined by the international obesity task force, in 1974, 1984, and 1994, for each sex and country.
  
  
  RESULTS
  Little change was found in the prevalence of overweight or obesity from 1974 to 1984. From 1984 to 1994 overweight increased from 5.4% to 9.0% in English boys (increase 3. 6%, 95% confidence interval 2.3% to 5.0%) and from 6.4% to 10.0% in Scottish boys (3.6%, 1.9% to 5.4%). Values for girls were 9.3% to 13. 5% (4.1%, 2.4% to 5.9%) and 10.4% to 15.8% (5.4%, 3.2% to 7.6%), respectively. The prevalence of obesity increased correspondingly, reaching 1.7% (English boys), 2.1% (Scottish boys), 2.6% (English girls), and 3.2% (Scottish girls).
  
  
  CONCLUSIONS
  These results form a base from which trends can be monitored. The rising trends are likely to be reflected in increases in adult obesity and associated morbidity.
