Snoring Risk Calculator

American Academy of Sleep Medicine (AASM) & STOP-BANG Criteria

The STOP-BANG Questionnaire is the international clinical standard for pre-operative and outpatient screening of Obstructive Sleep Apnea (OSA):

• The 8 STOP-BANG Parameters (1 Point Each):

• S (Snoring): Do you snore loudly (heard through closed doors)?

• T (Tired): Do you often feel tired, fatigued, or sleepy during the day?

• O (Observed): Has anyone seen you stop breathing or choking in your sleep?

• P (Pressure): Do you have or are you being treated for High Blood Pressure?

• B (BMI): Body Mass Index > 35 kg/m^2?

• A (Age): Age older than 50 years?

• N (Neck): Neck circumference > 17 in (43 cm) for men or > 16 in (41 cm) for women?

• G (Gender): Biological sex Male?

• Risk Stratification:

• Low Risk (0–2 Points): High negative predictive value for moderate-to-severe OSA.

• Intermediate Risk (3–4 Points): Moderate probability.

• High Risk (5–8 Points): Sensitivity > 93\% for moderate-to-severe OSA (AHI 15).

How to Use This Calculator

Enter your Snoring: Do you snore loudly (heard through closed doors or loud enough to disturb partner)? — select from Yes (1 point), No (0 points), Tired: Do you often feel tired, fatigued, or sleepy during daytime hours? — select from Yes (1 point), No (0 points), Observed: Has anyone observed you stop breathing, choke, or gasp during sleep? — select from Yes (1 point), No (0 points), Pressure: Are you being treated for High Blood Pressure (Hypertension)? — select from Yes (1 point), No (0 points), BMI: Is your Body Mass Index (BMI) greater than 35 kg/m²? — select from Yes (BMI > 35 / 1 point), No (BMI ≤ 35 / 0 points), Age: Are you older than 50 years old? — select from Yes (Age > 50 / 1 point), No (Age ≤ 50 / 0 points), Neck: Neck Circumference > 17 in (43 cm) for Men or > 16 in (41 cm) for Women? — select from Yes (Large Collar / 1 point), No (Normal Collar / 0 points), Gender: Is your biological sex Male? — select from Male (1 point), Female (0 points), and Clinical Sleep Case Benchmark — select from Custom Symptoms, High Risk Male (Age 52 / Snoring / Tired / High BP / Large Neck / 6 pts), Moderate Risk Female (Age 55 / Snoring / Daytime Fatigue / 3 pts).

The Formula

Scoring model for: Snoring Risk Calculator

Input factors assessed: Snoring: Do you snore loudly (heard through closed doors or loud enough to disturb partner)?, Tired: Do you often feel tired, fatigued, or sleepy during daytime hours?, Observed: Has anyone observed you stop breathing, choke, or gasp during sleep?, Pressure: Are you being treated for High Blood Pressure (Hypertension)?, BMI: Is your Body Mass Index (BMI) greater than 35 kg/m²?

Risk threshold breakpoints: 3.0, 5.0

The calculator applies a weighted scoring algorithm across the input factors listed above, then maps the total score to a risk category or recommendation using the threshold breakpoints shown.

Worked Example

A 52-year-old male truck driver with loud snoring and hypertension scores 5/8 on the STOP-BANG, prompting an at-home sleep study that confirms severe OSA and successful CPAP therapy.

Understanding Your Result

Health calculations based on standard clinical formulas give a population-reference estimate — individual variation exists. Compare your result to the reference ranges provided using validated sources (WHO, CDC, NIH, or specialty clinical guidelines). A single measurement is a starting point; meaningful health trends emerge from tracking the same metric over time under consistent conditions. For values outside reference ranges, consult a qualified healthcare provider before making changes to diet, exercise, or medication.
