How the liver disease and fatty liver risk is calculated
The assessment combines factors related to body shape, metabolism, alcohol, viral hepatitis and previous test results associated with liver disease.
This total score is a HealthSphere screening system that weights factors based on international health guidelines. It is not a WHO-endorsed score and cannot be used to diagnose disease.
Risk factor scoring table
| Factor | Criteria used | Points |
|---|---|---|
| Age | 35–44 / 45–59 / 60 years or over | 1 / 2 / 3 |
| BMI | 23–24.9 / 25–29.9 / 30 or over | 1 / 2 / 3 |
| Waist | Men ≥90 cm (35.4 in), women ≥80 cm (31.5 in); a further 10 cm over scores 3 | 2 / 3 |
| Alcohol | 1–2 times/week / almost every day | 1 / 3 |
| Related conditions | High blood sugar or diabetes / high blood lipids | 2 / 2 |
| Liver history | Hepatitis B/C virus / fatty liver or abnormal liver test results | 3 / 3 |
| Physical activity | Less than 150 minutes per week | 1 |
For each factor, only the single highest matching criterion is counted; all the points are then added up.
What the total score means
0–4 points — Low risk
5–8 points — Moderate risk
9 points or more — High risk
What the result cannot tell you
Assessing fatty liver and liver damage requires your medical history, blood tests and, in some cases, an ultrasound. This questionnaire cannot tell your liver test values or the stage of liver scarring (fibrosis), and cannot confirm a disease.
