PSG-assessed sleep efficiency and risk of incident CKD (stage ≥3): The ARIC-SHHS study
| Sleep Efficiency Quartiles | 1 | 2 | 3 | 4 | P Value Trend |
|---|---|---|---|---|---|
| Time in bed asleep, % | 71.36 | 82.80 | 88.31 | 93.48 | |
| Incident CKD, n | 116 | 128 | 119 | 98 | |
| Model 1 | 1 (reference) | 1.04 (0.81 to 1.33) | 0.93 (0.72 to 1.20) | 0.91 (0.69 to 1.20) | 0.88 |
| Model 2 | 1 (reference) | 1.05 (0.82 to 1.36) | 0.91 (0.70 to 1.18) | 0.91 (0.69 to 1.19) | 0.80 |
| Model 3 | 1 (reference) | 1.05 (0.81 to 1.35) | 0.92 (0.71 to 1.20) | 0.95 (0.72 to 1.25) | 0.93 |
| Model 4 | 1 (reference) | 1.09 (0.85 to 1.41) | 0.99 (0.76 to 1.28) | 0.97 (0.73 to 1.28) | 0.57 |
Model 1: Adjusted for age, sex, center, and education. Model 2: Adjusted for Model 1 + smoking, alcohol consumption, and physical activity. Model 3: Adjusted for Model 2 + BMI. Model 4: Adjusted for Model 3 + hsCRP, prevalent diabetes, systolic BP, diastolic BP, antihypertensive medications, and prevalent CHD.
