Multivariable Predictors of Screening for Sleep-Disordered Breathing and Associated Risk Scoring System*
| Characteristic | β Regression Coefficient (95% CI) | Screening Score Assigned |
|---|---|---|
| Sex | ||
| women | ref | 0 |
| men | 2.33 (1.52–3.14) | +4 |
| Body mass index, kg/m2† | 0.68 (0.45–0.91) | +1 |
| Blood pressure, mm Hg‡ | 0.73 (0.27–1.20) | +1 |
| Snoring§ | ||
| no or unknown | ref | 0 |
| yes | 2.02 (0.84–3.21) | +4 |
Screening score was assigned by dividing the β-coefficient by the absolute value of two-fifths of the amount added for the smallest and second-smallest coefficients in the model and rounding up to the nearest integer.
Body mass index categories: < 21.0, 21.0–22.9, 23.0–24.9, 25.0–26.9, 27.0–29.9, ≥ 30.
Blood pressure categories: systolic blood pressure (SBP) < 140 or diastolic blood pressure (DBP) < 90, SBP 140–159 or DBP 90–99, SBP160–179 or DBP 100–109, SBP ≥ 180 or DBP ≥ 110.
Snoring: snoring almost everyday or often is considered “yes,” and snoring sometimes or almost never is considered “no”.
