title: [Iodine prophylaxis in children population on the Wielkopolska Region area from year 1992 to 2005].
abstract: BACKGROUND
  The aim of the study was to evaluate of efficiency of iodine prophylaxis based on obligatory model of salt iodization.
  
  
  METHODS
  The study included 1444 children from the rural and urban area, with the proportional sex and age (8-12 years) distribution--432 children in 1992 (before salt iodization), 558 children in 2000 and 454 children in 2005 (during salt iodization from 1996).
  
  
  RESULTS
  The prevalence of goiter detected in children population in 1992 was 40% (recount by current criteria), in 2005 was reduced to 6% (p < 0.01). Parallel, median of urinary iodine concentration increased from 44 microg/l in 1992 to 107 microg/l (p < 0.01) in 2005. The increase of incidence of autoimmunological thyroid diseases is observed, especially chronic thyroiditis.
  
  
  CONCLUSIONS
  The study proves high efficiency of iodine prophylaxis in Wielkopolska Region, but it is still the area with mild iodine deficiency.
