Methods and systems for evaluating health risk factors by measurement of DNA damage and DNA repair
First Claim
1. A method to correlate the effect of at least one variable on at least one of DNA damage or DNA repair in an individual comprising the steps of:
- (a) using a plurality of assays to measure at least one of DNA damage or DNA repair in the individual;
(b) determining whether the amount of at least one of DNA damage or DNA repair as measured in the individual differs from the amount of at least one of DNA damage or DNA repair for a plurality of control samples; and
(c) determining if there is a correlation between the levels of at least one of DNA damage or DNA repair in the individual to changes in the variable.

Abstract
Disclosed are methods for measuring the effects of environmental, physiological, or lifestyle variables on DNA damage and DNA repair activity as well as the use of measurements of DNA damage and DNA repair activity to predict increased risk for disease. Embodiments of the methods involve the use of a combination of assays to measure DNA damage and DNA repair activity in an individual and comparing these measurements to suitable controls using the selected assays for normal healthy individuals of varying ages. In other embodiments, the methods may comprise a comparison of DNA damage levels to DNA repair levels to obtain an apparent net measurement of DNA damage accumulation.

20. A method to correlate effect of at least one of DNA damage or DNA repair to an increased or a decreased risk for disease in an individual comprising the steps of:
-
(a) using a plurality of assays to measure at least one of DNA damage or DNA repair in the individual;
(b) comparing the level of at least one of DNA damage or DNA repair in the individual to the control samples;
(c) determining if the amount of at least one of DNA damage or DNA repair as measured in the individual differs from the amount of at least one of DNA damage or DNA repair for a plurality of control samples; and
(d) determining if there is a correlation between a change in at least one of DNA damage or DNA repair and a change in the risk of the disease for the individual. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A method to correlate effect of at least one of DNA damage or DNA repair to an increased or a decreased risk for disease in an individual comprising the steps of:
-
(a) using a plurality of assays to measure at least one of DNA damage and DNA repair in the individual at an initial time;
(b) repeating the measurements of step (a) at one or more later time points measuring at least one of DNA damage and DNA repair in the individual at a later time;
(c) determining whether the amount of at least one of DNA damage or DNA repair as measured for at least one later time point differs from the amount of at least one of DNA damage or DNA repair at the initial time point; and
(d) determining if there is a correlation between a change in at least one of DNA damage or DNA repair and a change in the risk of the disease for the individual.
