This study aims to determine the impact of physical activity on asthma symptom reporting among children living in an inner city. Among 147 children aged 5-12 years with physician-diagnosed asthma, we assessed asthma symptoms using twice-daily diaries and physical activity using the physical activity questionnaire for children during three 8-day periods (baseline, 3 and 6 months). Linear, logistic, and quasi-poisson regression models were used to determine the association between physical activity and asthma symptoms; adjusting for age, sex, race, BMI, caregiver's education, asthma severity, medication use, and season. A 1-unit increase in PAQ score was significantly associated with reporting more nocturnal symptoms [risk ratio (RR): 1.03; 95% CI 1.00-1.06], daytime symptoms (RR: 1.04; 95% CI 1.00-1.09), being bothered by asthma (RR: 1.05; 95% CI 1.00-1.09), and trouble breathing (RR: 1.05; 95% CI 1.00-1.10). Level of physical activity should be taken into account in clinical management of asthma and epidemiological studies of asthma symptom burden.
