Prevalence of asthma and atopic symptoms in children aged 5-11years

Objective To assess prevalence of asthma and atopic symptoms in a group of school children aged 5- 11years and to look at prevalence of usage of asthma medications. Setting Three schools in Gampaha District in August 1998. Method A questionnaire translated into Sinhala was distributed to parents/guardians of 2195 children aged 5-11 years in Grades 1-5 of the schools and the filled questionnaires were collected through class teachers. Asthma, allergic rhinitis and eczema were defined using the clinical criteria of the International Study of Asthma and Allergic Conditions (ISAAC). Data was analysed using Epi Info version 6. Chi squared test and Chi squared test for trend were used for significance testing. Results Return rate of questionnaire was 93%. Sixty six percent were completed by mother, 30% by father and rest by guardian. Prevalence of asthma was 23% and of exercise induced asthma 11%. Prevalence rate of allergic rhinitis was 10% and eczema 3%. Within the specific group of asthma, in response to leading question "Has your child had asthma" only 19% of parents gave a positive answer. Prevalence of asthma in males did not significantly differ from that in females (p=0.5). A decreasing trend of asthma was observed with increasing age in girls (p less than 0.05). Eighty four percent of asthmatic children were using salbutamol orally and 9% without asthma in study population were also using salbutamol. Conclusions One in 5 children aged 5-11 years in study population had asthma but parental perception about asthma was poor. More than 80% of asthmatics had some medications for the disease.
