Prevalence of Bronchial Asthma among Secondary School Students
Abstract
Background: Bronchial asthma, a prevalent chronic respiratory condition, poses a significant health concern among secondary school students in Bangladesh, particularly in the bustling urban centers with associated environmental challenges. Objective: This study aimed to determine the prevalence of bronchial asthma and its associated factors among secondary school students. Method: This cross-sectional study, conducted from January to June 2023, aimed to assess the prevalence of bronchial asthma among 250 secondary school students (aged 10-15 yrs) in Bangladesh. The study employed a structured questionnaire, including the International Study of Asthma and Allergies in Childhood (ISAAC) asthma questionnaire, to collect socio-demographic details and assess asthma prevalence. Results: The findings revealed a mean age of 12.9 years, with an equal distribution of males and females. Notably, 11.6% had been diagnosed with asthma by a doctor. Factors such as sex, age, monthly family income, history of childhood pneumonia, and passive smoking exposure showed significant associations with bronchial asthma. Logistic regression analysis identified being male (OR=2.32, p=0.042), a history of childhood pneumonia (OR=3.10, p=0.007), and maternal asthma (OR=2.739, p=0.032) as predictors of bronchial asthma. The prevalence was higher in males and those with a history of childhood pneumonia or maternal asthma. Conclusion: This study emphasizes the need for comprehensive health initiatives…
