Objective: A cross-sectional study was conducted to determine if in-school physical activity (PA) varied by age, gender, weight and asthma status, participation in physical education (PE), outdoor recess, and other in-school PA among urban schoolchildren with asthma. Methods: PA was measured by tri-axial accelerometers. Height and mass were measured and overweight defined as BMI ≥85th percentile. Asthma impairment and risk were assessed as per national guidelines, and asthma status variable with three categories (mild, moderate, and severe) was created. Multivariable generalized linear mixed models adjusting for clustering due to school and student were fitted to identify variables predictive of PA. Results: 108 children with asthma participated. Children spent 374 minutes in school, of which 253 minutes were sedentary, 105 minutes in light PA, and 16 minutes in moderate-to-vigorous PA (MVPA). Only 3 participants reached the recommended ≥30 minutes/day of MVPA. Multivariable analysis revealed age, gender, participation in PE class, outdoor recess, and other in-school PA as independent predictors of PA. BMI and asthma status were not associated with PA. Conclusions: Children with asthma were mostly sedentary at school. Older children and girls were particularly at risk for inactivity. PE, recess, and other in-school PA participation are modifiable factors that should be targeted in school-based interventions aimed at increasing PA in this population.
