title: [Trends of hospitalization rates from asthma in children and adolescents in Poland].
abstract: Hospitalization rates from asthma in children and adolescents below 19 years of age showed a consistent rising trend over the last two decades and in the period 1984-1996 the rates were doubled in both genders. Among boys the rates were 1.6 times higher than in girls. On average the rates increased annually by 12.2% in boys and by 10.6% in girls. The fastest increase has been noted in the youngest children in the age 0-4 years (20.3% in boys and 18.9% in girls). In the older age groups (5-9 and 10-14 years) the annual increase was in the range of 10.5-14.1%. The slowest increase was observed in children in the oldest age group (3.7%) and in the latter age group there was no differences in hospitalization rates between both genders. We found the highest rates in the southeastern and northern part of the country and this was not compatible with the hygienic hypothesis of asthma and allergic diseases.
