OBJECTIVE: To assess the prevalence of asthma and wheeze and factors associated with it in children aged 6-7 and 13-14 years. METHOD: School based, prospective survey using self/parental reporting of occurrence of asthma or wheeze on pre-designed questionnaire. RESULTS: Out of 112 schools, 17 and 15 schools were randomly selected for recruitment of subjects in age group 6-7 and 13-14 years, respectively. Prevalence of asthma and wheeze reported were 2.3% and 6.2%, respectively, in age group 6-7 years and 3.3% and 7.8%, respectively, in age group 13-14 years. On the basis of adjusted odds ratio, risk factors for wheeze or asthma were tertiary education of mother, antibiotic use in the first year of life, eating pasta or fast-food or meat once or more per week and exercise once or more/week while the protective factors were intake of vegetables once or more and fruits thrice or more per week. In univariate analysis, breastfeeding was also found to be protective. CONCLUSION: Promotion of rational use of antibiotic in first year of life, avoidance of fast food and promotion of breastfeeding and intake of fruits and vegetables may reduce the risk of asthma/wheeze and should be encouraged.
