STOP-Bang Questionnaire: How to Know If You're at Risk for Sleep Apnea
What Is the STOP-Bang Questionnaire?
The STOP-Bang is an 8-question screening tool developed by sleep researchers at the University of Toronto.
It’s now widely used in hospitals and sleep clinics around the world to identify people who may have obstructive sleep apnea (OSA).
Each “Yes” answer scores 1 point, and the total (0–8) reflects your estimated risk.
The acronym STOP-Bang stands for:
| Letter | Question | Example |
|---|---|---|
| S | Snoring | Do you snore loudly (louder than talking or heard through closed doors)? |
| T | Tired | Do you often feel tired, fatigued, or sleepy during the day? |
| O | Observed | Has anyone observed you stop breathing during sleep? |
| P | Pressure | Do you have or are you being treated for high blood pressure? |
| B | BMI | Is your body mass index greater than 35 kg/m²? |
| A | Age | Are you older than 50 years? |
| N | Neck circumference | Is your neck circumference greater than 40 cm (16 inches)? |
| G | Gender | Are you male? |
How to Interpret Your STOP-Bang Score
| Total Score | Risk Level | Interpretation |
|---|---|---|
| 0–2 | Low risk | Unlikely to have sleep apnea |
| 3–4 | Intermediate risk | Possible mild to moderate sleep apnea |
| 5–8 | High risk | Strong likelihood of moderate to severe sleep apnea |
💡 People with scores ≥5 are highly recommended to get a sleep study or use a validated sleep monitoring app like SnailSleep to analyze snoring and breathing pauses overnight.
Why the STOP-Bang Test Is Important
Sleep apnea affects over 1 billion adults globally (Lancet Respiratory Medicine, 2022), but up to 80% remain undiagnosed.
It’s not just about snoring — untreated sleep apnea increases your risk of:
- Heart disease and high blood pressure
- Type 2 diabetes
- Stroke and cognitive decline
- Daytime sleepiness leading to accidents
Early screening using STOP-Bang can save lives — literally.
Real-Life Example
Case: David, 46, software engineer
David’s wife noticed his loud snoring and occasional choking at night. He took the STOP-Bang test and scored 6.
After a week of sleep recording using SnailSleep, his snoring pattern revealed periodic breathing interruptions every 2–3 minutes.
Following a clinical sleep study, David was diagnosed with moderate obstructive sleep apnea and began CPAP therapy.
Three months later, his fatigue disappeared, and his blood pressure dropped from 150/95 to 125/80 mmHg.
Combining STOP-Bang with Digital Sleep Tracking
Apps like SnailSleep can enhance your screening accuracy by detecting:
- Snoring frequency and intensity
- Breathing pauses
- Oxygen level fluctuations (via Apple Watch integration)
- Sleep stage disruptions caused by apnea events
Pairing your STOP-Bang score with objective sleep data offers a more reliable picture before seeing a doctor.
Example: A user with a STOP-Bang score of 4 but frequent recorded snoring episodes may still be at moderate risk and should seek evaluation.
Improving Sleep After a High STOP-Bang Score
If your result shows moderate or high risk:
- Consult a sleep specialist — request a polysomnography (sleep lab test).
- Adopt healthy lifestyle changes: lose weight, avoid alcohol before bed, and sleep on your side.
- Track your progress: Use a sleep quality app like SnailSleep to monitor snoring and nighttime awakenings.
- Try breathing exercises: Slow diaphragmatic breathing before bed may reduce airway collapse risk.
Data Snapshot: The Global Picture
A 2024 review by the World Sleep Society found:
- 22% of adults in North America meet STOP-Bang “high risk” criteria.
- Men are 2.5× more likely than women to show elevated scores.
- The highest risk group? People aged 50–70 with BMI >30.
FAQ
Q — Can I rely only on the STOP-Bang test for diagnosis?
A — No, it’s a screening tool. For diagnosis, you need a sleep study or detailed overnight monitoring.
Q — Can women develop sleep apnea?
A — Yes. Though the “G” in STOP-Bang refers to male gender as a higher risk factor, postmenopausal women have rising prevalence.
Q — What if I scored low but still snore?
A — Snoring alone can affect sleep quality. Use SnailSleep to monitor snoring frequency and evaluate improvement after sleep hygiene changes.
