title: [Prevalence of overweight and obesity in 9 and 10 year-old children in the Principality of Asturias: evaluation bias by parents].
abstract: BACKGROUND
  Overweight and obesity in children is a very important issue in the field of health. The aim of this study was to determine the prevalence of overweight and obesity in pre-adolescent children aged 9 to 10 years old in the Principality of Asturias, and to assess the reliability of the measurements of weight and height reported by parents.
  
  
  METHODS
  A sample of 291 subjects, 142 girls and 149 boys were chosen at random from the network of schools in the Principality of Asturias. They were weighed and measured individually at the school. All participants brought the signed consent of their parents, which also contained the anthropometric measurements of they made of their children.
  
  
  RESULTS
  The results showed that 28.17% of children aged 9 and 10 years old in the Principality of Asturias were overweight and 15.80% obese. This means that 44% of the sample had some degree of overweight. Data reported by parents underestimated the weight of both the boys and girls by an average of 2.07kg.
  
  
  CONCLUSIONS
  The high percentage of excess weight observed is due to the categorisation system used (IOFT) and the age of the sample. The results call into question the research with data indirectly recorded data.
