title: Adolescent obesity in Lebanese private schools.
abstract: BACKGROUND
  Obesity has become a public health problem worldwide. Our objective was to calculate the prevalence of overweight and obesity.
  
  
  METHODS
  It is a cross sectional study of adolescents in private Lebanese schools, aged 10-18 years. Gender, birth date and measures of weight and height were recorded.
  
  
  RESULTS
  In 12,299 adolescents, we found high prevalence of obesity (7.5%) and at risk of obesity (24.4%). In girls, risk of obesity and obesity prevalence decrease with increasing age (P < 10(-4)) as compared with that in boys.
  
  
  CONCLUSIONS
  Early recognition of obesity should become routine in paediatric ambulatory care settings.
