title: [Analysis of agreement between self-reported and observed information on pubertal development among school girls].
abstract: OBJECTIVE
  To test the reliability of the self-classification concerning levels of breast and public hair development among female adolescents of different socioeconomic groups.
  
  
  METHODS
  A total of 445 female adolescents attending three secondary schools located in Ribeirão Preto, State of S. Paulo, Brazil, were studied. After being familiarised with Tanner's tables of breast and public hair development, the adolescents were asked to self classify themselves according to these variables. The results were compared to those obtained by a physical examination carried out soon after.
  
  
  RESULTS
  Agreement rates between referred and observed information on breast development varied from 57.3% to 65.2%. For public hair the values varied from 65.4% to 73.5%. Total agreement rates for breast and public hair development, when considered simultaneously, reached values below 50.0% in the three schools. However, high agreement rates were observed for some critical degrees, such as B2, B4 and PH4.
  
  
  CONCLUSIONS
  Significant events, such as the beginning of pubertal development, the menarche and the showing down of the body's development growth could be determined with acceptable levels of agreement. The low agreement rates observed for the simultaneous analysis of the degree of both breast and public hair show the need for the perfecting of methodologies that can replace the physical examination of adolescents, once reliable information about pubertal development is obtained in field studies.
