| LTPA, Mean±SD (range) (MET-h/week) | 0±0 | 1.0±0.4 (0.1–1.7) | 2.8±0.7 (1.8–4.2) | 7.1±1.9 (4.3–10.9) | 20.1±8.9 (11.1–48.1) | |
| Total ACQ score† (0–6) | 1.10 | 0.92 | 1.03 | 0.92 | 0.84 | p=0.037 |
| Predicted good control* | Ref | 0.87 (0.38–2.00) | 0.98 (0.43–2.22) | 0.84 (0.37–1.91) | 2.47 (1.06–5.73) | |
| Total AQLQ score† (1–7) | 5.27 | 5.29 | 5.23 | 5.49 | 5.49 | p=0.058 |
Bolding indicates values that are statistically significant.
All analyses adjusted for age, sex, ICS dose and season recruited in.
*Good control=ACQ score ≤0.8.
†As the analyses were conducted using multiple imputation, it is not appropriate to include SDs with the mean scores.
ACQ, asthma control questionnaire; AQLQ, asthma quality of life questionnaire; ICS, inhaled corticosteroid; LTPA, leisure time physical activity; MET, metabolic equivalent.
