Self-Reported Physical Activity and Asthma Risk in Children.

ABSTRACT:

Background

Increased physical activity (PA) may protect against asthma but PA can trigger asthma symptoms.

Objective

To investigate relationships between moderate-to-vigorous PA (MVPA) assessed during routine care visits and incident asthma.

Methods

For this retrospective cohort, 542,486 children between 2 and 17 years from 2010 to 2017 were included who had an MVPA assessment (exercise vital sign) during routine care visits. The association of MVPA and asthma was analyzed using Cox proportional hazards regression models as a function of age, with MVPA and body mass index (BMI) being time-varying factors, adjusted for race and ethnicity, socioeconomic status, and air pollution.

Results

The mean MVPA was 5.4 (standard deviation: 4.4) hours/week. Crude asthma inc
