Recent epidemiological studies shows that this trend seems to be stopped in many countries.Aim: To estimate the trend of asthma symptoms prevalence among school children in north-west part of Croatia.Methods: Results of two studies conducted eight years apart, during school years 2001/02 vs. 2009/10, on the same area using the same written and video asthma questionnaires developed by the International Study of Asthma and Allergies in Childhood were compared respectively. The target population comprised two age groups: 6-7years (n=1634 vs. n=1052) and 13-14 years (n=2194 vs. n=1181).Results: Prevalence of asthma symptoms in the older age group according to written questionnaire (wheezing in last 12 months: 8.4 vs 14.0, p<0.001; wheezing ever: 19.9 vs. 26.1, p<0.001; asthma ever: 5.2 vs. 6.9, p=0.02) showed a rising trend as well as according to video questionnaire (wheezing in last 12 months: 4.6 vs. 6.4, p=0.01; severe wheezing in last 12 months; 2.1 vs. 7.1, p<0.001). There was no significant (NS) change in the prevalence of the same symptoms in the younger age group (wheezing in last 12 months: 9.7 vs. 9.4, p=NS; wheezing ever: 26.2 vs. 26.3, p=NS; asthma ever: 3.9 vs. 5.0, p=NS).Conclusion: Prevalence of asthma symptoms among older school children in north-west part of Croatia still shows a rising trend. Results obtained in the younger age group of children may suggest that this trend could be stopped in the future. ER -
