Table 3.
Variable | β coefficient (n = 137)a | P Value |
---|---|---|
Weight (10 lb) | 0.02b | 0.15 |
BMI (kg/m2) | 0.03 | 0.11 |
Body fat, (%) | 0.02 | 0.13 |
Neck (cm) | 0.01 | 0.80 |
Waist (cm) | 0.01 | 0.13 |
Waist:hip (10--1) | 0.01 | 0.28 |
Age- and race-adjusted estimates of the effect of each measure of body size on ln(respiratory disturbance index [RDI]+1).
Sample sizes were smaller for neck circumference, body fat percentage, waist circumference, and waist-to-hip ratio due to missing data.
Because of the properties of the natural logarithm, this corresponds to an approximate 2% greater change in RDI per ± 10-pound difference in weight (and analogously for the other predictors).
