Starting 1 January 2026, an amendment to the Czech preventive-checkup regulation includes waist circumference in routine general-practitioner checkups as a cardiometabolic risk marker. The GP checkup itself stays publicly funded and irreplaceable — InBody, Max Pulse, and blood-pressure readings never substitute for it. They can add trends in fat, muscle, pressure and other values between visits, but they cannot determine the cause of a changing waistline.
Decree No. 403/2025 Coll., effective from 1 January 2026, amended Decree No. 70/2012 Coll. For adult general preventive checkups it expressly added waist circumference to the basic physical examination. The regular GP checkup remains publicly funded once every two years; the insured person is entitled to it, but attendance is not a legal duty imposed on the patient.
Laboratory and diagnostic coverage also expanded, but not every test is performed at every visit for every adult. The initial checkup after registration has a broader baseline; later blood count, lipid, glucose, kidney or liver tests and ECG depend on age, interval, available results and individual risk.
Do not infer your exact checkup from a short summary. Confirm it with your GP based on age, history and prior results. Decree 403/2025 is the primary legal source; the Czech National Health Information Portal gives a practical age- and risk-specific explanation updated for 2026.
Waist circumference is a simple anthropometric marker used as indirect context for abdominal fat and cardiometabolic risk. Results depend on the chosen protocol and measurement site, so trend comparisons should use the same validated method each time; this article does not present one anatomical line as universally correct.
Its advantage is a quick tape measurement without imaging equipment. That makes it useful in a routine GP examination when it is measured and interpreted within a standard clinical context.
Waist circumference alone cannot distinguish subcutaneous from visceral fat or determine individual health risk. Interpretation also depends on factors such as sex, age, population background and other risk factors; using the same measurement method matters for comparisons. Two people with the same waist measurement need not have the same metabolic risk.
InBody analysis uses bioimpedance to estimate body composition by segment — trunk, arms and legs. Segmental outputs describe the distribution of fat-free and fat mass, but they are not an anatomical map or direct imaging of where tissue sits.
InBody 970 also reports a modelled estimate of visceral fat area that you can follow over time. This is not direct imaging of the abdomen or an exact measurement of the amount of fat around the organs; like waist circumference, it is an indirect indicator.
Two people with the same waist circumference can have different overall muscle and fat profiles. InBody adds a useful body-composition estimate, but segmental analysis alone cannot reliably explain why a person has a particular waist size. Read tape-measured waist and bioimpedance estimates alongside each other rather than treating one as a replacement for the other.
| Area | Waist circumference | InBody |
|---|---|---|
| What it measures | A single number – waist size | Estimates of fat and fat-free mass by body segment |
| Provides a separate visceral-fat estimate | No | Yes, as a modelled estimate of visceral fat area; it is not direct imaging or a map of every fat depot |
| Distinguishes fat from muscle | No | Estimates fat and fat-free components |
| Typical frequency | Usually at a preventive checkup, roughly every 2 years | As needed, typically every few months |
| Replaces a doctor? | No, it's part of a medical checkup | No, it's a supplementary orientation-level measurement |
A publicly funded preventive checkup every two years provides regular clinical assessment. Body composition or blood pressure can change between visits; if you have symptoms or a concerning result, contact your doctor rather than waiting for the next checkup.
You can track tape-measured waist circumference and InBody results between checkups according to your goals, for example a few months apart under comparable conditions. Measure blood pressure at home as your doctor advises and interpret repeated, correctly taken readings; a universal interval of several months does not apply to blood pressure.
Compare like with like and interpret changes in context. Individual bioimpedance or HRV readings can vary with measurement conditions; even a series of readings cannot by itself establish what caused a change or whether health has improved.
A larger-than-recommended waist circumference, a higher visceral fat reading on InBody, or a borderline blood-pressure value aren't a diagnosis. They're a signal that the result is worth watching more closely and discussing in a broader context — alongside other values and with a professional.
If an expanded preventive checkup turns up an elevated waist measurement together with other flagged values — say, a lipid panel or glucose reading outside the usual range — that's worth discussing with your GP, not interpreting on your own at home. Your doctor has context a single number can't provide.
InBody can add a trend in estimated fat and fat-free mass, while Max Pulse provides its own outputs. They do not show the precise anatomical location of fat and do not replace lab work, an ECG or a clinical exam; they can add context for a conversation with your doctor.
The two roles are clearly separate. An insured person is entitled to a publicly funded GP preventive checkup, but attendance is not a legal duty imposed on the patient. The exact lab and ECG schedule depends on whether the visit is initial, plus age and risk. InBody, Max Pulse and portal blood-pressure readings are supplementary private measurements and cannot replace the clinical checkup.
In practice, the combination works best this way: complete your funded checkup on the schedule your GP recommends, and between visits, track the trend on your InBody portal — waist-adjacent measures like visceral fat, along with muscle mass and other indicators, all in one place, with a history you can compare at any time.
If you want a clearer picture of where you actually stand — not just one number at the waist — an InBody 970 measurement gives you a more detailed baseline to work with between doctor visits.

Decree No. 403/2025 Coll. took effect on 1 January 2026 and added waist circumference to the basic physical exam. Laboratory tests and ECG depend on whether the checkup is initial, age, intervals, risk and available results. Confirm your exact schedule with your GP.
Waist circumference is a simple marker of abdominal adiposity associated with cardiovascular and metabolic risk. It can be measured quickly with a tape, but it cannot by itself quantify visceral fat or establish an individual diagnosis.
No. InBody, Max Pulse, and blood-pressure readings don't replace a medical exam, an ECG, or lab tests — they're orientation-level, supplementary measurements that make sense between funded checkups, not instead of them.
Risk generally rises as waist circumference increases, but the exact thresholds vary between sources and populations and depend on other factors like height and sex. Interpreting your specific number is a job for your doctor, ideally alongside the rest of your checkup results.
A general GP preventive checkup is scheduled every two years. Depending on your goals, you can repeat an InBody measurement after a few months under comparable conditions. Consult a doctor sooner if you have symptoms or unusual results.
From 2026, a GP preventive checkup includes waist circumference and additional tests according to age and risk. Between visits, InBody can add an orientation-level trend in estimated fat and muscle mass, not an anatomical map or diagnosis. Compare like with like and take health questions to your GP.
