AbstractThe prevalence of bronchial asthma appears to have increased continuously since the 1970s, and bronchial asthma now affects an estimated 4 to 7% of people worldwide. Trends in childhood bronchial asthma from population-based prevalence and routine statistics in India were reviewed. The prevalence of bronchial asthma increased in a secular trend. The prevalence of a life-time diagnosis of bronchial asthma increased in all age groups. The incidence of new childhood bronchial asthma episodes increased. The objective of this study was to determine the prevalence of childhood bronchial asthma in India. Problem Statement: Bronchial asthma prevalence studies lack consistency, possibly because of the ill-defined diagnostic criteria and non standardized study protocols. From some of the important community survey reports, the median prevalence of childhood bronchial asthma in India was determined to be 3.3% (with IQR = 2.3-13.8%). Conclusion: Research during recent years suggests that the prevalence of childhood bronchial asthma has been on the rise. Due to a lack of nationally representative data on the prevalence, risk factors, and prognosis of the disease, there is an urgent need for more public health research in this direction.
