  FIG. 3 is a sequence diagram showing a flow of processing in the visceral fat information calculation apparatus according to the first embodiment of this invention.

  First, the visceral fat information calculation terminal 101 acquires medical examination information from the medical examination information management unit 120 of the database 106 (903). The regression coefficient calculation unit 111 calculates regression coefficient information based on the acquired medical examination information, and stores the calculated regression coefficient information 906 in the regression coefficient management unit 122 of the database 106 (906).

  Next, the visceral fat information calculation terminal 101 acquires regression coefficient information from the regression coefficient management unit 122 (907). The approximate expression creation unit 112 creates an approximate expression indicating the relationship between the average value of age and the regression coefficient of the total fat area based on the acquired regression coefficient information. Furthermore, the calculation formula creation unit 105 creates a visceral fat age calculation formula based on the created approximate formula. The created approximation formula and the created visceral fat age calculation formula are stored in the calculation formula information management unit 123 of the database 106 as calculation formula information.

  Next, the visceral fat information calculation terminal 101 acquires calculation formula information from the calculation formula information management unit 123 (910), substitutes the user data input to the input unit 102 into the calculation formula, and calculates the visceral fat information. . The calculated visceral fat information is stored in the visceral fat information management unit 125 of the database 106 (911). Then, the visceral fat information calculation terminal 101 acquires the visceral fat information from the visceral fat information management unit 125 (912), and displays the acquired visceral fat information on the output unit 104.

  As described above, the visceral fat information calculation apparatus according to the first embodiment of the present invention calculates a regression coefficient from medical examination information managed by the database 106, and creates an approximate expression and a visceral fat age calculation expression. Then, the information input from the input unit 102 is substituted into the created visceral fat age calculation formula to calculate the visceral fat age. Thereby, the age of the visceral fat considering the age and the visceral fat area and the subcutaneous fat area can be known.

  Next, details of the processing will be described using a flowchart and a sequence diagram. First, a procedure for creating a visceral fat age calculation formula using medical examination information acquired from the database 106 will be described.

  FIG. 4 is a flowchart illustrating an example of a flow of processing for creating a visceral fat age calculation formula using medical examination information acquired from the database 106 according to the first embodiment of this invention.

  The creation of the visceral fat age calculation formula starts when the medical examination information of FIG. 2 is input from the input unit 102 and registered in the database 106 (501). The registered medical examination information is managed by the medical examination information management unit 120.

  In the total fat area calculation step 502, first, the visceral fat information calculation terminal 101 acquires the visceral fat area 213 and the subcutaneous fat area 214 from the medical examination information management unit 120. Next, the total fat area calculation unit 110 calculates the total fat area by adding the visceral fat area 213 and the subcutaneous fat area 214 for each medical examination ID 201.

  Next, in the regression coefficient calculation step 503, the visceral fat information calculation terminal 101 acquires the age 205 from the medical examination information management unit 120. The age category editing unit 115 classifies the age in 5-year increments, and calculates the average value of the age for each category. The age group and the calculated average age value for each category are stored in the regression coefficient management unit 122. Next, the regression coefficient calculation unit 111 uses the data of all subjects included in the age category for each age category, and the total fat area calculated by the total fat area calculation unit 110 using the visceral fat area as a target variable Is used as an explanatory variable, a regression analysis without a constant term (visceral fat area = C × total fat area) is performed, and a regression coefficient C of the total fat area is calculated (503). The calculated regression coefficient C of the total fat area is stored in the regression coefficient management unit 122.

  FIG. 5 is an explanatory diagram illustrating an example of regression coefficient information managed by the regression coefficient management unit 122 according to the first embodiment of this invention.

  The regression coefficient management unit 122 manages the age category 301, the average age value 302, and the regression coefficient 303 of the total fat area. As described above, information calculated by the age category editing unit 115 and the regression coefficient calculation unit 111 is stored.

  For example, the entry 311 has an average age of 37 years old in the category of 35 to 39 years old, and using the data of persons in this category, the visceral fat area is a target variable and the total fat area is a constant as an explanatory variable. When a regression analysis without a term is performed to calculate a regression coefficient, the regression coefficient of the calculated total fat area is 0.42 (visceral fat area = 0.42 × total fat area).

  Based on this regression coefficient information, it can be considered that the regression coefficient of the total fat area varies depending on the age. In other words, since the ratio of the visceral fat area to the total fat area (visceral fat area + subcutaneous fat area) varies depending on the age, not only the relation between the visceral fat area and the age, but also the relation between the subcutaneous fat area and the age. A more appropriate formula for calculating visceral fat age that takes into account

  Returning to the description of FIG.

  In the approximate expression creation step 504, first, the visceral fat information calculation terminal 101 acquires regression coefficient information from the regression coefficient management unit 122. Next, the approximate expression creation unit 112 creates an approximate expression indicating the relationship between the average value 302 of age and the regression coefficient 303 of the total fat area.

  This makes it possible to consider that the regression coefficient 303 of the total fat area varies depending on the age. In other words, since the ratio of the visceral fat area to the total fat area (visceral fat area + subcutaneous fat area) varies depending on the age, not only the relation between the visceral fat area and the age, but also the relation between the subcutaneous fat area and the age. Can also be considered.

For example, as for the relationship between the average value 302 of age and the visceral fat area ratio indicated by the regression coefficient 303 of the total fat area, the visceral fat area ratio increases as the age increases, but the increase rate tends to decrease. There is. Therefore, when approximated by a quadratic expression, the approximate expression is visceral fat area ratio = G × age ² + H × age + I. However, G, H, and I are coefficients. The created approximate expression is stored in the calculation formula information management unit 123.

  In the visceral fat age calculation formula creation step 505, the calculation formula creation unit 105 creates a visceral fat age calculation formula using the visceral fat area ratio as an input value from the approximate formula created by the approximate formula creation unit 112. When the approximate formula created by the approximate formula creation unit 112 is a quadratic formula, the visceral fat age calculation formula is expressed by the following formula according to the formula of the solution.

  The created visceral fat age calculation formula is stored in the calculation formula information management unit 123.

  FIG. 6 is an explanatory diagram illustrating an example of calculation formula information managed by the calculation formula information management unit 123 according to the first embodiment of this invention.

  The calculation formula information management unit 123 manages the approximate formula 401 and the visceral fat age calculation formula 402.

  As described above, the information calculated by the approximate expression creation unit 112 and the calculation formula creation unit 105 is stored.

  By the above processing, not only the visceral fat area but also the subcutaneous fat area can be taken into consideration, and therefore a visceral fat age calculation formula for calculating the visceral fat age that more appropriately represents the visceral fat accumulation state of the user can be created. The created visceral fat age calculation formula is stored in the calculation formula information management unit 123. This completes the creation of the visceral fat age calculation formula (507).

  Next, the flow of processing until the user's actual age, visceral fat area, and subcutaneous fat area are input from the input unit 102 and visceral fat information is displayed will be described.

  FIG. 7 is a flowchart illustrating an example of a processing flow from when the user information is input from the input unit 102 until the visceral fat information is displayed according to the first embodiment of this invention.

  The visceral fat information calculation terminal 101 starts processing (701).

  In the user information input step 702, first, the visceral fat information calculation terminal 101 displays a screen for inputting user information on the output unit 104.

  FIG. 8 is an explanatory diagram illustrating an example of an input screen displayed on the output unit 104 according to the first embodiment of this invention.

  A user information input screen 820 is displayed on the output unit 104. The user information input screen 820 displays a visceral fat area input field 830, a subcutaneous fat area input field 831, an actual age input field 832, and an execution button 821 for determining input of user information.

  The visceral fat information calculation terminal 101 causes the user to take an image of the abdomen using an image diagnostic apparatus such as an X-ray CT of the input unit 102 to acquire an abdomen image. Then, the visceral fat information calculation terminal 101 gives the user the visceral fat area, subcutaneous fat area, and actual age calculated from the abdominal CT value using the mouse or keyboard of the input unit 102, respectively. The input field 830, the subcutaneous fat area input field 831, and the actual age input field 832 are input, and when the input is completed, the user is instructed to operate the execution button 821. The input visceral fat area, subcutaneous fat area, and actual age are stored in the visceral fat information management unit 125.

  In the visceral fat area ratio calculating step 703, the visceral fat area ratio calculating unit 114 calculates the total fat area (visceral fat area + subcutaneous fat area) from the visceral fat area and the subcutaneous fat area input in the user information input step 702. A visceral fat area ratio indicating the ratio of the visceral fat area is calculated. The calculated visceral fat area ratio is stored in the visceral fat information management unit 125.

  In the visceral fat age calculation step 704, first, the visceral fat information calculation terminal 101 acquires the visceral fat age calculation formula 402 from the calculation formula information management unit 123. Next, the visceral fat age calculation unit 107 substitutes the visceral fat area ratio calculated in the visceral fat area ratio calculation step 703 into the obtained visceral fat age calculation formula 402 to calculate the visceral fat age. The calculated visceral fat age is stored in the visceral fat information management unit 125.

  In the difference calculating step 705, the difference calculating unit 108 calculates the difference between the visceral fat age calculated by the visceral fat age calculating unit 107 and the actual age input in the user information input step 702. To do. The difference from the calculated actual age is stored in the visceral fat information management unit 125.

In the visceral fat obesity determination step 709, the visceral fat obesity determination unit 109 determines whether or not the visceral fat obesity is based on the visceral fat area input in the user information input step 702. Specifically, when the visceral fat area is 100 cm ² or more, it is determined as visceral fat obesity. When the visceral fat area is less than 100 cm ² , it is determined not to be visceral fat obesity. The determination result is stored in the visceral fat information management unit 125.

  FIG. 9 is a diagram illustrating an example of the visceral fat information managed by the visceral fat information management unit 125 according to the first embodiment of this invention.

  The visceral fat information management unit 125 manages the age 600 of the user, the visceral fat age 601, the difference 602 from the actual age, the visceral fat area 604, the subcutaneous fat area 605, and the visceral fat obesity determination 603.

  In the user's age 600, visceral fat area 604, and subcutaneous fat area 605, the values input in the user information input step 702 are stored. The visceral fat age 601 stores the visceral fat age calculated in the visceral fat age calculating step 704. The difference from the actual age is stored in the difference 602 from the actual age in the difference calculation step 705 from the actual age.

The visceral fat obesity determination 603 stores the determination result of the visceral fat obesity determination step 709.
For example, if it is determined that the patient is visceral fat obesity, Yes is stored. Further, when it is determined that the fat is not visceral fat obesity, No is stored.

  Next, in the visceral fat information display step 710, first, the visceral fat information calculation terminal 101 acquires the visceral fat information from the visceral fat information management unit 125 and displays it on the output unit 104.

  Hereinafter, a display method of visceral fat information will be described.

  FIG. 10 is an explanatory diagram illustrating an example of visceral fat information displayed on the output unit 104 according to the first embodiment of this invention.

  The visceral fat information calculation terminal 101 displays the user's abdomen image input from the input unit 102 and information stored in the visceral fat information management unit 125 as a visceral fat information display screen 801 on the output unit 104.

The visceral fat information display screen 801 includes a user abdomen image 804 captured by the input unit 102,
Visceral fat area display column 810, subcutaneous fat area display column 811, age display column 812, visceral fat age display column 813, difference display column 814 between visceral fat age and actual age, and visceral fat obesity determination result display column 815 are displayed. To do. The user's abdomen image 804 photographed by the input unit 102 includes a visceral fat image 802 and a subcutaneous fat image 803.

  As a display method of the visceral fat obesity determination result display field 815, when it is determined that it is visceral fat type obesity, it indicates that it is visceral fat type obesity, and when it is determined that it is not visceral fat type obesity, Display that the type is not obese.

  As described above, the regression coefficient calculation unit 111 performs regression analysis without a constant term using the visceral fat area as an objective variable and the total fat area (visceral fat area + subcutaneous fat area) as explanatory variables for each age category. The visceral fat area ratio (ratio of the visceral fat area to the total fat area) indicated by the regression coefficient of the total fat area is calculated. Next, the approximate expression creating unit 112 creates an approximate expression indicating the relationship between the average value of age for each age category and the visceral fat area ratio, and the calculation formula creating unit 105 calculates the visceral fat area from the created approximate expression. Create a visceral fat age calculation formula with the ratio as an input value. This makes it possible to consider the relationship in which the visceral fat area ratio increases as the age increases, and not only the visceral fat area but also the relationship between the subcutaneous fat area and the age, so the user's visceral fat accumulation state is more appropriate The visceral fat age calculation formula can be created.

  Further, in the visceral fat information calculation device according to the present invention, the visceral fat information creation unit 103 calculates the difference between the visceral fat age and the actual age of the user using a visceral fat age calculation formula using the visceral fat area ratio as an input value. Since it is displayed, it is possible to convey the visceral fat accumulation state of the user in an easy-to-understand manner.

  In the first embodiment of the present invention, the visceral fat information calculation device causes an abdominal image to be taken by an image diagnostic device such as X-ray CT, and the visceral fat area and the subcutaneous fat area are displayed on the user information input screen using a mouse or a keyboard. Although it is manually input to 820, an image diagnosis apparatus such as an X-ray CT may be automatically input by connecting to the visceral fat information calculation apparatus of the present invention. In addition, when user data is stored in the medical examination information management unit 120 even when the age is input, the information may be extracted from the database and automatically input. This saves the user input.

  In the first embodiment of the present invention, the example of calculating the visceral fat age using the user's visceral fat area and the subcutaneous fat area measured by an image diagnostic apparatus such as X-ray CT has been described. The present invention is not limited to this.

  For example, the visceral fat area estimated value and the subcutaneous fat area estimated value may be calculated from the abdominal circumference that can be easily measured by the user, and the visceral fat age may be calculated using these values.

  In order to realize the above-described method, the visceral fat information calculation terminal 101 includes a visceral fat area estimation formula and an abdominal fat area estimation formula creation unit that creates a subcutaneous fat area estimation formula, a created visceral fat area estimation formula, And an abdominal fat area estimated value calculation unit that calculates a visceral fat area estimated value and a subcutaneous fat area estimated value by inputting the user's abdominal circumference in the subcutaneous fat area estimation formula.

  Specifically, first, the abdominal fat area estimation formula creation unit uses the medical examination information stored in the medical examination information management unit 120 to perform regression analysis with the visceral fat area as an objective variable and the abdominal circumference as an explanatory variable. The visceral fat area estimation formula (estimated visceral fat area = D × abdominal circumference + E) is created. However, D and E are coefficients.

  Similarly, the abdominal fat area estimation formula creation unit uses the medical examination information stored in the medical examination information management unit 120 to perform regression analysis using the subcutaneous fat area as an objective variable and the abdominal circumference as an explanatory variable, An estimation formula (estimated subcutaneous fat area = M × abdominal circumference + N) is created. However, M and N are coefficients.

  Next, the abdominal fat area estimated value calculation unit calculates the visceral fat area estimated value and the subcutaneous fat area estimated value by inputting the user's abdominal circumference into the created visceral fat area estimated expression and the subcutaneous fat area estimated expression .

  Then, the visceral fat area ratio calculation unit 114 calculates the visceral fat area ratio from the visceral fat area estimated value and the subcutaneous fat area estimated value, and the visceral fat age calculation unit 107 calculates the visceral fat area calculated by the visceral fat age calculation formula Visceral fat age is calculated by substituting the ratio.

  In this way, by calculating the visceral fat age from the abdominal circumference that can be easily measured by the user, it is not necessary for the user to go to a facility such as a hospital having an image diagnostic apparatus to measure the visceral fat area and the subcutaneous fat area, The visceral fat accumulation state can be grasped more easily. In addition, there is no need to pay for an expensive imaging fee, and it is possible to avoid exposure when measured with an X-ray CT apparatus.

  Further, in the first embodiment of the present invention, the example in which the visceral fat age is calculated using the visceral fat area and the subcutaneous fat area of the user measured by a large diagnostic imaging apparatus such as X-ray CT has been described. However, the visceral fat age may be calculated using an abdominal circumference that can be easily measured by the user and an input of a subcutaneous fat area that can be measured by a small measuring device using infrared rays or ultrasonic waves.

  In order to realize the above-described method, the visceral fat information calculation terminal 101 calculates a total fat area estimation formula by creating a total fat area estimation formula and substituting the user's abdominal circumference input to the input unit. A total fat area estimated value calculating unit that calculates a value, and a built-in fat area estimated value calculating unit that calculates a visceral fat area estimated value.

  Specifically, first, the total fat area estimation formula creation unit uses information on a plurality of abdominal circumferences 208 in the medical examination information and information on a plurality of total fat areas calculated by the total fat area calculation unit, Regression analysis is performed using the total fat area as an objective variable and the abdominal circumference as an explanatory variable, and a total fat area estimation formula (estimated total fat area = P × abdominal circumference + Q) is created. However, P and Q are arbitrary constants.

  Next, the total fat area estimated value calculation unit calculates the total fat area estimated value by substituting the user's waist circumference 208 into the created total fat area estimation formula, and the visceral fat area estimated value calculation unit is calculated. The estimated visceral fat area is calculated by subtracting the subcutaneous fat area of the user from the estimated total fat area.

  The visceral fat area ratio calculation unit 114 calculates the visceral fat area ratio from the calculated visceral fat area estimated value and the subcutaneous fat area 214.

  The visceral fat age calculation unit 107 calculates the visceral fat age by substituting the visceral fat area ratio calculated in the visceral fat age calculation formula.

  As described above, by calculating the visceral fat age from the abdominal circumference that can be easily measured and the subcutaneous fat area that can be measured with a small measuring device using infrared rays or ultrasonic waves, even without a large diagnostic imaging device The visceral fat accumulation state can be easily grasped.

  In the first embodiment of the present invention, the regression coefficient calculation unit 111 uses the data of all subjects included in the age category for each age category, the visceral fat area as the objective variable, and the total fat area As an explanatory variable, a regression analysis without a constant term was performed, and the visceral fat area ratio indicated by the regression coefficient of the total fat area was calculated, but for each age category, the average value of the visceral fat area ratio was calculated, It is good also as a regression coefficient of a fat area. As a result, the calculation can be simplified.

[Second Embodiment]
A second embodiment of the present invention will be described in detail with reference to the drawings.

  The second embodiment of the present invention will be described with reference to a visceral fat information calculation device that displays a visceral fat area estimated value, a subcutaneous fat area estimated value, and a visceral fat age when a user's abdominal circumference is input. The usage scene is assumed to be in a car.
