Association of BMI with sleep parameters in obese and healthy-weight children with asthma.
| Variable | Obese Asthma (r, P) | Healthy-Weight Asthma (r, P) |
|---|---|---|
| SE (%) | −0.19, 0.001 | −0.27, < 0.001 |
| AAIa | 0.1, 0.09 | −0.001, 0.99 |
| % Time in N1 | 0.19, 0.002 | 0.27, < 0.001 |
| % Time N2 | 0.18, 0.003 | 0.08, 0.32 |
| % Time in N3 | −0.3, < 0.001 | −0.18, 0.03 |
| % Time in REM sleep | −0.18, 0.002 | −0.04, 0.59 |
| PLMIa | −0.05, 0.39 | −0.01, 0.87 |
| AHIa | 0.28, < 0.001 | 0.19, 0.03 |
| Baseline O2 saturation (%) | −0.24, 0.0001 | 0.02, 0.77 |
| O2 saturation nadir | −0.18, 0.003 | −0.07, 0.38 |
| Baseline ETCO2 (mm Hg) | 0.14, 0.03 | −0.02, 0.84 |
| Peak ETCO2 | 0.12, 0.07 | −0.005, 0.96 |
aReported in events/h. AAI = arousal awakening index, AHI = apnea-hypopnea index, BMI = body-mass index, ETCO2 = end-tidal carbon dioxide, PLMI = periodic limb movement index, REM = rapid eye movement, SE = sleep efficiency.
