Direct answer
STOP-BANG sums eight yes/no OSA risk factors (max 8). Teaching bands: 0–2 low, 3–4 intermediate, 5–8 high screening risk. Not a sleep-study diagnosis — confirm with HSAT or polysomnography when indicated.

STOP-BANG score: 5 / 8
High questionnaire risk for obstructive sleep apnea
Multiple high-yield factors are positive. Formal sleep testing is usually warranted to confirm AHI severity and guide CPAP or alternative therapy—not questionnaire score alone.
Positive factors
Screening only
This is not diagnostic. Confirm with sleep study (home sleep apnea test or polysomnography) and clinician interpretation before treatment decisions.
| Letter | Factor | Criterion | Points |
|---|---|---|---|
| S | Snoring | Loud, habitual snoring reported by patient or bed partner | +1 |
| T | Tiredness | Daytime tiredness, fatigue, or unrefreshing sleep | +1 |
| O | Observed apnea | Witnessed breathing pauses, choking, or gasping during sleep | +1 |
| P | Pressure (hypertension) | History of high blood pressure or on antihypertensive therapy | +1 |
| B | BMI | Body mass index greater than 35 kg/m² | +1 |
| A | Age | Age greater than 50 years | +1 |
| N | Neck circumference | Large neck: typically >40 cm (16 in) men; >37 cm (15 in) women | +1 |
| G | Gender | Male sex (higher OSA prevalence in derivation cohorts) | +1 |
| Score | Tier | Typical action |
|---|---|---|
| 0–2 | Low screening risk | Routine sleep hygiene; test if symptoms persist or worsen |
| 3–4 | Intermediate screening risk | Clinical review; consider home sleep apnea test (HSAT) or polysomnography |
| 5–8 | High screening risk | Prompt sleep evaluation; avoid drowsy driving; address cardiometabolic comorbidity |
