Body mass index
Adult BMI
BMI is weight in kilograms divided by the square of height in metres. Adult categories below follow the World Health Organization’s standard ranges. BMI is only one measure. It does not distinguish muscle from fat, and it can be less useful in pregnancy, for people under 18, for some athletes, and for some ethnic groups or older adults.
Waist-to-height ratio
Waist compared with height
Divide waist circumference by height, using the same units. A commonly used public-health guide is to keep your waist less than half your height (a ratio under 0.5). This is a general educational rule of thumb, not a personal diagnosis. Clinicians may also use sex- and ethnicity-specific waist measurements. Measure the waist at the mid-point between the lower rib and the top of the hip, after a normal breath out.
Prevention
Australian screening explorer
This explorer summarises who national programs usually invite or consider, based on published Australian Government information current at the time of writing (checked November 2026). Eligibility also depends on individual history, symptoms and clinical judgement. It is not a personal screening plan.

Programs and ages can change. Confirm details with the official program pages or your clinician. If you have symptoms, do not wait for a screening invitation — see a doctor.
Heart and circulation
Cardiovascular risk — official Australian calculator only
ATM Health does not calculate cardiovascular risk on this website. The 2023 Australian guideline and AusCVDRisk calculator are intended for health professionals. In people without known atherosclerotic cardiovascular disease, assessment is generally considered for adults aged 45–79 years, for people with diabetes aged 35–79, and for Aboriginal and Torres Strait Islander people aged 30–79 (with individual risk-factor assessment from 18–29).
If you want to understand your cardiovascular risk, talk with your usual general practitioner. They can decide whether the official calculator is appropriate and how to interpret it.
Official tool
AusCVDRisk calculator
Opens the Australian Government–supported calculator at cvdcheck.org.au. It is a clinical tool, not a consumer self-test designed to replace a consultation.
