Table 2. Health measures stratified by distance to I-93.
| Health measure | Total (N=140) | ≤50 m (N=20) | 51–500 m (N=95) | >1,000 m (N=25) |
|---|---|---|---|---|
| BMI, mean (SD)a | 29.2 (6.9) | 32.9 (8.4)b | 29.3 (6.6) | 26.0 (5.5) |
| hsCRP mg/l, median (IQR) | 1.62 (2.8) | 1.92 (4.4) | 1.92 (2.9) | 0.94 (1.0) |
| IL-6 pg/ml, median (IQR) | 1.61 (2.3) | 1.63 (2.9) | 1.78 (2.1) | 0.97 (0.8) |
a
Sample size differs due to missing BMI values ≤50 m (n=19); 51–500 m (n=89); and >1,000 m (n=25).
b
Indicates significant (P≤0.05) difference between ≤50 m and >1,000 m distance groups.
