What it calculates

The “QRISK3” calculator computes 10-year CVD risk (QRISK3) in % from 21 parameters: female (1 = yes), age (years), ethnicity (1 white/not stated, 2 indian, 3 pakistani, 4 bangladeshi, 5 other asian, 6 black caribbean, 7 black african, 8 chinese, 9 other), smoking (0 never, 1 ex-smoker, 2 <10/day, 3 10–19/day, 4 ≥20/day), diabetes (0 none, 1 type 1, 2 type 2), height (cm), body weight (kg), total cholesterol/hdl ratio, systolic bp (mmHg), sd of systolic bp (≥2 recent readings) (mmHg), angina or heart attack in a first-degree relative <60 years (1 = yes), ckd stage 3–5 (1 = yes), atrial fibrillation (1 = yes), on blood pressure treatment (1 = yes), migraine (1 = yes), rheumatoid arthritis (1 = yes), systemic lupus erythematosus (1 = yes), severe mental illness (1 = yes), atypical antipsychotics (1 = yes), regular oral corticosteroids (1 = yes), erectile dysfunction — men only (1 = yes).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Female (1 = yes) = 1, Age = 64 years, Ethnicity (1 White/not stated, 2 Indian, 3 Pakistani, 4 Bangladeshi, 5 other Asian, 6 Black Caribbean, 7 Black African, 8 Chinese, 9 other) = 2, Smoking (0 never, 1 ex-smoker, 2 <10/day, 3 10–19/day, 4 ≥20/day) = 0, Diabetes (0 none, 1 type 1, 2 type 2) = 0, Height = 178 cm, Body weight = 80 kg, Total cholesterol/HDL ratio = 4, Systolic BP = 180 mmHg, SD of systolic BP (≥2 recent readings) = 20 mmHg, Angina or heart attack in a first-degree relative <60 years (1 = yes) = 0, CKD stage 3–5 (1 = yes) = 0, Atrial fibrillation (1 = yes) = 0, On blood pressure treatment (1 = yes) = 0, Migraine (1 = yes) = 0, Rheumatoid arthritis (1 = yes) = 0, Systemic lupus erythematosus (1 = yes) = 0, Severe mental illness (1 = yes) = 0, Atypical antipsychotics (1 = yes) = 0, Regular oral corticosteroids (1 = yes) = 0, Erectile dysfunction — men only (1 = yes) = 0 the result is 17.2 % (Townsend deprivation score set to 0 (no UK postcode entered)).

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
