Description

TECHNICAL FIELD

The present invention relates to a device and a method for visualizing variation in the risk of diseases in accordance with changes in environmental factors, and more particularly, to a device and a method which calculate a risk of diseases by retaining a value with respect to genetic factors and changing a value with respect to environmental factors, among factors influencing an occurrence of disease, and visualize the risk of diseases calculated on the basis of the changes in the environmental factors.

BACKGROUND ART

Various disease-related or phenotype-related gene mutation (SNP or mutation) markers are being revealed by genome sequence decoding and disease study (Genome-wide association study: GWAS). For example, it is reported that BRCA1 or BRCA2 gene mutations increase the possibility of diseases such as breast cancer.

Accordingly, various methods for predicting the possibility of occurrence of disease or non-disease phenotypes of a subject by utilizing various genetic markers reported through existing scientific researches have been reported (Cited Document: Schrodi S J et al. Front. Genet. 2014) and domestic and foreign genetic testing institutions also predict/test the possibility of diseases on the basis of the calculation of the genetic risk of disease and phenotype by utilizing a similar method.

However, for the occurrence of the disease or phonotype, a lot of genetic factors and environmental factors (for example, a lifestyle) interact with each other and complexly affect. Accordingly, only when the risk of diseases is calculated by considering not only the possessed genetic factors, but also the environmental factors such as a lifestyle, exact prediction and analysis may be achieved.

The genetic factor which influences the disease cannot be improved by an individual (because it is difficult to improve without using a specific technique such as gene scissors), but in the case of the environmental factor which influences the disease, risk factors may be controlled by improving the lifestyle so that consequentially, the possibility of occurrence of disease may be improved. When a genetic test result is provided, if a degree of change in the risk of diseases in accordance with the change of current lifestyle (improved or deteriorated) is calculated to be presented, it is expected that a subject may numerically/visually ascertain how to improve or retain the environmental factors and ultimately and make behavioral changes to more actively form better habits for preventing the diseases.

However, there has not been a technique to calculate how the risk of disease is changed when the environmental factors such as current lifestyle is changed (improved or deteriorated) and visualize the result. As illustrated in FIG. 1, there is a technique to show a changed value of risk in accordance with individual environmental factors with respect to two factors of “smoking” and “obesity”, among various environmental factors. However, according to this technique, the risk is calculated first by considering only the genetic risk factor, without taking into account the current lifestyle of the subject, and then only a value of the risk which changes in accordance with the reported environmental factor states is shown. That is, referring to FIG. 1, my current state is not considered, but changes in the value, for all number of cases of environmental factors, which has been reported through the existing papers are simply applied to be presented. In the case of lung cancer, only when the genetic factor of the subject is considered, the risk is analyzed to be 0.84. Further, according to the epidemiological investigation which has been reported, it was reported that when a patient smokes, the risk is 6.99 times higher than that of non-smokers and when a patient smoked, but stopped smoking, the risk is increased by 3.5 times that of non-smokers. Therefore, the risk for the non-smoking case shows a value obtained by multiplying 0.84 of a genetic factor and 1 of an environmental factor in accordance with the non-smoking, the risk for a stopping-smoking case shows a value obtained by multiplying 0.84 of a genetic factor and 3.5 of an environmental factor in accordance with stop-smoking, and the risk for a smoking case shows a value obtained by multiplying 0.84 of a genetic factor and 6.99 of an environmental factor in accordance with smoking.

MODES OF THE INVENTION

Hereinafter, exemplary embodiments of a device and a method for visualizing variation in the risk of diseases in accordance with changes in environmental factors according to the present invention will be described in detail with reference to the accompanying drawings.

First, a device for visualizing variation in the risk of diseases in accordance with changes in environmental factors according to an exemplary embodiment of the present invention will be described with reference to FIGS. 2 to 4.

FIG. 2 is a block diagram for explaining a device for visualizing variation in the risk of diseases in accordance with changes in environmental factors according to an exemplary embodiment of the present invention, FIG. 3 is a view for explaining an example of visualization of the risk of diseases according to an exemplary embodiment of the present invention, and FIG. 4 is a view for explaining another example of visualization of the risk of diseases according to an exemplary embodiment of the present invention.

Referring to FIG. 2, a device 100 for visualizing variation in the risk of diseases in accordance with the changes in environmental factors according to an exemplary embodiment of the present invention calculates a risk of diseases by retaining a value with respect to genetic factors and changing a value with respect to environmental factors, among factors influencing an occurrence of diseases and visualizes the risk of diseases calculated on the basis of the changes in the environmental factors.

To this end, the device 100 for visualizing variation in the risk of diseases may include a storage unit 110, a risk-of-disease calculating unit 130, and a display unit 150.

The storage unit 110 stores disease-causing factor information. Here, the disease-causing factor information includes information for every disease, about genetic factors and environmental factors which influence an occurrence of the diseases.

For example, the disease-causing factor information may be acquired by collecting genetic markers (genetic factors) with respect to diseases (or phenotype) and environmental markers (environmental factors) from existing materials such as papers together with effect sizes of each marker (factor). Generally, the effect size of the marker with respect to a disease may be calculated by one of an odds ratio, a relative risk, a risk ratio, and a hazard ratio.

The risk-of-disease calculating unit 130 calculates a current risk of diseases and a changed risk of diseases of a user with respect to predetermined diseases, on the basis of disease-causing factor information stored in the storage unit 110. Here, in order to calculate the current risk of diseases or the changed risk of diseases, various existing methods may be used.

That is, the risk-of-disease calculating unit 130 may calculate the current risk of diseases of the user for a predetermined disease using a current value of the user for the genetic factor and the environmental factor which influence the occurrence of the predetermined disease, on the basis of the disease-causing factor information.

For example, referring to the following Table 1, if environmental factors influencing occurrence of stomach cancer are drinking, smoking, and a body mass index (BMI) and the current value (current lifestyle) of the user for the environmental factor (lifestyle) is as represented in the following Table 1, the current risk of diseases of the user with respect to the stomach cancer takes the “fiftieth place”. The risk of diseases according to the following Table 1 is just an example and the risk of diseases is calculated by various existing calculating methods and thus may be represented by various methods such as scores, a multiple, a rank, or a level.

TABLE 1
			User's current
Environmental	Value		value
factor	(Lifestyle)	Effect size	(Current lifestyle)	User's risk of disease
Drinking	Heavy drinking	1.26 times		Fiftieth place/100
	Appropriate	1.06 times	•	person
	drinking			(one example of
	Little or not	1 time		indicating risk by
	drinking			representing place out of
Smoking	Smoking	1.56 times	•	100 people/the closer to
	Non-smoking	1 time		the first place, the larger
BMI	Obesity	1.41 times		the risk)
	Overweight	1.10 times	•
	Normal weight	1 time

Further, the risk-of-disease calculating unit 130 may calculate a changed risk of diseases of the user with respect to the predetermined disease using a current value of the user for the genetic factor influencing the occurrence of a predetermined disease and using a changed value on the basis of the current value of the user for the environmental factor influencing the occurrence of the predetermined disease, on the basis of the disease-causing factor information. That is, the risk-of-disease calculating unit 130 may calculate the changed risk of diseases by retaining a value for the genetic factor, but changing a value for the environmental factor, among factors influencing the occurrence of the disease. Here, the changed value on the basis of the current value of the user may be a value improved from the current value of the user or a value deteriorated from the current value of the user.

In this case, when there is a plurality of environmental factors which influences the occurrence of the predetermined disease, the risk-of-disease calculating unit 130 may calculate a changed risk of diseases of the user using the value changed on the basis of the current value of the user, with respect to at least one of environmental factors, among the plurality of environmental factors. For example, if there are three environmental factors, the risk-of-disease calculating unit 130 may calculate the changed risk of diseases of the user using the changed value with respect to one environmental factor or two or three environmental factors.

Further, the risk-of-disease calculating unit 130 may calculate the changed risk of diseases of the user plural times by changing a changed value on the basis the current value of the user, with respect to the environmental factor influencing the occurrence of the predetermined disease. For example, the changed risk of diseases of the user is calculated using “A” as the current value of the user with respect to the environmental factor, the changed risk of diseases of the user is calculated again using “B” as the current value of the user with respect to the environmental factor, and the changed risk of diseases of the user may be calculated again using “C” as the current value of the user with respect to the environmental factor.

For example, referring to the following Table 2, the environmental factor influencing the occurrence of the stomach cancer is drinking, smoking, and BMI (body mass index) and the changed risk of diseases of the user with respect to the stomach cancer may be calculated by changing (improving or deteriorating) the current value (current lifestyle) of the user with respect to the environmental factor. The changed degree of the value for the environmental factor according to the following Table 2 is just an example, and the changed degree may be set in various manners.

TABLE 2

The display unit 150 visualizes and outputs the current risk of diseases and the changed risk of diseases of the user calculated by the risk-of-disease calculating unit 130.

Further, when the changed risk of diseases is calculated plural times by the risk-of-disease calculating unit 130, the display unit 150 may visualize and output the current risk of diseases of the user calculated by the risk-of-disease calculating unit 130 and a plurality of changed risks of diseases.

At this time, when the display unit 150 visualizes the current risk of diseases of the user and the plurality of changed risks of diseases, the display unit 150 may visualize a ranking of the risk of the current user among all the users together.

For example, as illustrated in FIG. 3, not only the ranking of the user for a specific disease according to the current risk of diseases is displayed, but also how much the risk of diseases which may be improved/deteriorated according to the change of the environmental factor (lifestyle) is changed may be displayed. In addition, as illustrated in FIG. 4, a change in the ranking of the risk of diseases expected when an environmental factor (lifestyle) is changed is displayed to allow the user to specifically ascertain which environmental factor (lifestyle) needs to be improved and how the risk of diseases is changed when the current good environmental factor (lifestyle) is deteriorated.

In the meantime, although the device 100 for visualizing variation in the risk of diseases according to an exemplary embodiment of the present invention has been described as one independent device, that is, the device 100 for visualizing variation in the risk of diseases calculates the current risk of diseases of the user, calculates a changed risk of diseases in accordance with the change in the environmental factor, and visualizes and outputs the calculated current risk of diseases and changed risk of diseases, it is not limited thereto. According to the exemplary embodiment, the device 100 for visualizing variation in the risk of diseases according to the present invention may be installed in a user terminal (not illustrated) such as a smart phone or a notebook as an application to perform the operation according to the present invention.

Now, a method for visualizing variation in the risk of diseases on the basis of changes in environmental factors according to an exemplary embodiment of the present invention will be described with reference to FIG. 5.

FIG. 5 is a flowchart for explaining a method for visualizing variation in the risk of diseases in accordance with changes in environmental factors according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the device 100 for visualizing variation in the risk of diseases calculates a current risk of diseases of the user with respect to a predetermined disease on the basis of disease-causing factor information (S110). Here, the disease-causing factor information includes information for every disease, about genetic factors and environmental factors which influence the occurrence of the diseases.

That is, the device 100 for visualizing variation in the risk of diseases may calculate the current risk of diseases of the user with respect to a predetermined disease using a current value of the user for the genetic factor and the environmental factor which influence the occurrence of the predetermined disease, on the basis of the disease-causing factor information.

Further, the device 100 for visualizing variation in the risk of diseases calculates a changed risk of diseases of the user with respect to a predetermined disease on the basis of disease-causing factor information (S130).

That is, the device 100 for visualizing variation in the risk of diseases may calculate a changed risk of diseases of the user with respect to the predetermined disease using a current value of the user for the genetic factor influencing the occurrence of a predetermined disease and using a changed value on the basis of the current value of the user for the environmental factor influencing the occurrence of the predetermined disease, on the basis of the disease-causing factor information. Here, the changed value on the basis of the current value of the user may be a value improved from the current value of the user or a value deteriorated from the current value of the user.

In this case, when there is a plurality of environmental factors which influences the occurrence of the predetermined disease, the device 100 for visualizing variation in the risk of diseases may calculate a changed risk of diseases of the user using the changed value on the basis of the current value of the user, for at least one of environmental factors, among the plurality of environmental factors.
