title: [Agreement between adolescents' self-perceived weight and body mass index (BMI)].
abstract: OBJECTIVE
  Determining agreement between adolescent students' self-perceived weight and body mass index (BMI) in Bogotá, Colombia.
  
  
  METHODS
  This was exploratory research in which a group of 321 12-18 year-old (mean=14.4; SD=1.6) adolescent students participated: 206 girls and 115 boys. Agreement between self-perceived weight (0=low, 1=adequate and 2=high) and BMI was estimated using Spearman's correlation (r s); the authors' expected r s was higher than 0.6.
  
  
  RESULTS
  It was found that self-perceived weight was low in 48 students (15.0 %), adequate in 228 (71.0 %) and high in 45 of them (14.0 %). BMI ranged from 14.5 to 29.8 (mean=20.5; SD=3.0). Overall r s was 0.4 amongst boys and girls, 0.5 in girls and 0.3 in boys.
  
  
  CONCLUSIONS
  Agreement was low between the adolescents' self-perceived weight and their actual BMI; these measurements were not interchangeable. Further research is needed to corroborate the findings.
