The relationship between prevalence of asthma and environmental factors in rural households.
A cross sectional study was conducted among 1007 children aged 1-2 years, from padi farming area. The percentage of male children was 51.4%. The prevalence of at least one of the chronic respiratory symptoms was 12.81%, and the prevalence of chronic cough, chronic sputum, wheezing and bronchial asthma as diagnosed by doctors were 9.33%, 3.87% 5.36% and 3.38% respectively. The overall prevalence of bronchial asthma was 6.26%. The prevalence of asthma was highest among children aged 11-12 years (8.9%) and higher among males (6.95%). No significant relationship was found between the prevalence of either chronic respiratory disease symptoms of bronchial asthma, and selected environmental factors, namely exposure to cigarette smoke, use of mosquito coil and wood stove. However there was a significant relationship between prevalence of asthma in children and history of asthma among parents and grandparents.
