title: [Age at menarche in girls with sense organs impairments].
abstract: OBJECTIVE
  The aim of the study was to assess the age at menarche in girls with chronic diseases of senses organs.
  
  
  METHODS
  The sample consisted of 179 girls (87 with hearing defects and 92 with sight defects) aged from 10 to 16 years of age. All subjects were pupils of Special Schools for Deaf Children and Youth or Centres of Training for Blind and Sight Impairment Children in Wrocław and Kraków (Poland). Using the status quo method age at menarche was estimated.
  
  
  RESULTS
  Median age at menarche via probit analysis was 12.62 +/- 0.18 for girls with hearing impairments and 13.11 +/- 0.21 for girls with impairments of sight. The earliest age at menarche was observed in deaf girls and blind girls (12.56 +/- 0.20 and 12.82 +/- 0.32, respectively).
  
  
  CONCLUSIONS
  The more severe the impairment of the sense organ, the earlier was the age at menarche.
