The Associations Between Gait Speed and Sleep Quality (N=193)
| Study Variables | Model 1* | Model 2** | ||||
|---|---|---|---|---|---|---|
| β | 95% CI | p-value | β | 95% CI | p-value | |
| Gait speed (km/h) | −3.15 | −3.82 to −2.47 | <0.001 | −2.88 | −3.53 to −2.22 | <0.001 |
| Sex (1=men; 2=women) | 1.45 | 0.19 to 2.72 | 0.025 | 0.85 | −0.34 to 2.05 | 0.162 |
| Age (years) | 0.40 | −0.10 to 0.90 | 0.117 | 0.03 | −0.38 to 0.43 | 0.896 |
| Body-mass index (kg/m2) | 0.04 | −0.23 to 0.32 | 0.751 | 0.01 | −0.24 to 0.26 | 0.950 |
| Self-rated health (scale 1–5) | −0.59 | −1.36 to 0.18 | 0.131 | 0.08 | −0.58 to 0.74 | 0.813 |
| Smoking status (% of “yes”) | 1.36 | −0.01 to 2.74 | 0.050 | 0.88 | −0.22 to 1.99 | 0.117 |
| Psychological distress (scale 0–24) | 0.37 | 0.22 to 0.52 | <0.001 | 0.25 | 0.11 to 0.40 | <0.001 |
Notes: *Model 1: examine the associations between gait speed and sleep quality, where sex, age, body-mass index, self-rated health, smoking status, and psychological distress were entered separately into the model; **Model 2: examine the associations between gait speed and sleep quality-adjusted for sex, age, body-mass index, self-rated health, smoking status, and psychological distress; p<0.05.
