- Pediatric asthma outcomes worsen with increased sedentary time and decreased aerobic activity in school-age children with past or current asthma.
Why this matters
- These factors are both modifiable and warrant attention in this patient population.
- 35.7% of the participants had overweight or obesity.
- Lower aerobic fitness was linked to having had past asthma or having current asthma or asthma attacks and wheeze with exercise or with activity limitations.
- More sedentary time, for example, screen time, was linked to higher rates of these outcomes as well.
- Obesity and overweight were not linked to asthma-related outcomes.
- Average endurance values were significantly lower in children with asthma or asthma history vs control participants.
- Obesity or overweight exacerbated this effect in children with asthma compared with normal-weight children without asthma.
- Days of physical activity showed a weak correlation with endurance values.
- 665 children were included, about 12% of whom had current asthma.
- Funding: National Center for Advancing Translational Sciences.
- Cross-sectional study that does not establish temporal associations.
- Physical activity not measured objectively.
- Asthma information based on questionnaires.
