Abstract

The invention describes a method to evaluate the health risks of a study subject by comparing blood chemistry risk factors by means of a database with data of multiple patients, sorted by age and sex and concerning their measured risk factors, mortality and causes of death. In order to enable advantageous risk estimation, it is proposed that the risk factor data stored in the database and sorted by sex, age groups and risk factors are combined into value groups according to quantile types with the help of a computer programme, that the study subject is assigned a quantile based on his/her gender and age as well as on his/her risk factor values, that the mortality risk in the study subject'"'"'s quantile range determined based on the deaths within predetermined mortality periods having a cause that can be referred back to the pertinent risk factors is compared with the corresponding mortality risk of the quantile range of an order that is still safe in regard to the pertinent risk factors, and that the relative mortality risk of the study subject calculated therefrom is indicated as a function of a predetermined threshold value being exceeded.

Claims

1. Method to evaluate the health risks of a study subject by comparing blood chemistry risk factors by means of a database with data of multiple patients, sorted by age and sex and concerning their measured risk factors, mortality and causes of death, wherein, with the help of a computer program, the risk factor data stored in the database and sorted by sex, age groups and risk factors are combined into value groups by way of quantiles, wherein the study subject is assigned a quantile depending on his/her gender and age as well as on the values of the risk factors, wherein the mortality risk in the study subject'"'"'s quantile range calculated by means of the deaths within predefined mortality periods that are ascribable to a cause that can be referred back to the pertinent risk factors is comparted with the corresponding mortality risk of the quantile range of an order that is still safe with regard to the pertinent risk factors, and wherein the relative mortality risk of the study subject calculated therefrom is indicated as a function of a predetermined threshold value being exceeded.

2. Method according to claim 1, wherein the quantile of a still sage order with regard to the pertinent risk factors is defined as being the quantile comprising 20% of all recorded patients.

3. Method according to claim 1, wherein the threshold value for the indication of an increased relative mortality shall be 2.

4. Method according to claim 1, wherein in addition to total cholesterol, HDL cholesterol and triglycerides, glucose and gamma glutamyl transferase are measured as risk factors.
