The present invention relates to an apparatus and method for analyzing abdominal obesity by analyzing abdominal fat using the value of abdominal impedance or trunk impedance.

Obese people feel less independence of body behavior than normal people, slow response to stimulation, decrease muscle-to-weight ratio, and reduce deception, which leads to a decrease in overall exercise ability and lower quality of life. In addition, it causes various diseases such as stroke, hypertension, hyperlipidemia, heart disease, joint pain, low back pain, and shortens lifespan. In particular, the increase in the percentage of body fat to the abdomen is the most important risk factor for various metabolic diseases such as ischemic heart disease (myocardial infarction, angina), cerebrovascular disorders (cerebral infarction, cerebral hemorrhage), insulin-independent diabetes mellitus and various adult diseases. It is an important factor that adversely affects. This obesity problem must be prevented and monitored early.

In general, it is possible to quantitatively measure the body composition of the trunk of the limbs through the analysis of body composition through multi-frequency analysis and measurement of partial body impedance. However, the body fat of the torso does not represent abdominal obesity. This is because visceral fat, subcutaneous fat and fat of the upper abdomen, which are the main determinants of abdominal obesity, cannot be measured separately. Therefore, abdominal obesity is measured through the measurement of partial body impedance through the existing limb electrodes (both arms and legs) It cannot be measured quantitatively.

The abdominal analysis through the conventional body composition analyzer is separated into the body (Ztrunk), arms, both legs impedance model using the bioelectrical impedance method to measure the impedance of each part, and the electrode for measuring the impedance, wrist, hand Impedance of the measurement site was measured by using the ankles or the soles as the transverse or longitudinal region of the specific site. Using the measured impedance, regression formula using visceral fat and subcutaneous fat area measured by CT is used. In the conventional method for displaying abdominal obesity in body composition analysis, the standard range is known according to age by various clinical experiments as shown in FIG. 2, and the standard range is set as the age and the vertical axis is set as the visceral fat. Therefore, the visceral fat area corresponding to the standard is plotted as the visceral fat standard area 100, and the normal range is indicated by drawing a horizontal axis in the visceral fat area corresponding to 100 cm ² and judged according to the age and visceral fat area of the subject. do. In the conventional case, the standard range and age of visceral fat 100 cm ² according to various clinical trials are used as a normal standard.

3 is a result of analyzing the visceral fat in the conventional body composition analyzer, visceral obesity type item 110, visceral / subcutaneous fat content item 120, abdominal obesity rate item 130, subcutaneous type / internal equipment only analysis item 140 ).

Built-in obesity type item 110 is divided into five types of subcutaneous type, balanced type, vigilance, visceral obesity, high level internal equipment only, level 1 ~ 4 is subcutaneous type, level 5 ~ 8 is balanced type, boundary Level 9 ~ 10, internal obesity level 11 ~ 15, altitude internal equipment only 16 ~ 20, indicating that the level of the internal organs Obesity is severe.

Visceral / subcutaneous fat items (120) showed the amount of visceral fat and subcutaneous fat, respectively.

The abdominal obesity rate item 130 indicates a visceral fat-subcutaneous fat ratio (VSR) according to the test result.

The subcutaneous / internal only analysis items are divided into CT tomographic findings of subcutaneous and visceral obesity type. If they are subcutaneous type, they appear as “((((subcutaneous type)))” in the subcutaneous type and “((((internal device only)) type ) ".

As described above, the conventional analysis of abdominal obesity has a limitation of clinical effectiveness in determining and displaying abdominal obesity or visceral obesity in the abdominal obesity rate (VSR) according to the age, sex, and physical information of the skinny and obese subjects or subjects. . In addition, it is not clear whether the clinical validity test suitable for the evaluation of abdominal obesity in the method and the results of clinical trials in the standard range and normal range by the clinical trials used in this conventional technique was made. In addition, the evaluation of abdominal obesity in subjects with different body types (age, gender, weight, height, abdominal circumference) is simply applied to the standard range according to age, and the normal range (100 cm ² ) without considering the abdominal circumference of the subject is applied. There is a limitation of clinical effectiveness in the analysis of abdominal obesity.

Therefore, the present invention calculates the abdominal circumference of the subject by measuring the abdominal or torso impedance of the subject to display the classification by more than the standard, standard, less than the standard according to height, age, gender, and to display the visceral fat area and subcutaneous fat area Quantitatively calculated and displayed numerically. In addition, by displaying the previous measurement results and the current measurement results at the same time, it provides the results for the patient to efficiently and correctly control and maintain abdominal obesity.

It is an object of the present invention to provide an apparatus and method for analyzing abdominal obesity for analyzing abdominal fat using values of abdominal impedance or trunk impedance.

Another technical problem to be achieved by the present invention is to use a regression equation whose parameter is the impedance of the abdominal cross section between the trunk (Ztrunk) or lumbar spine 4 ~ 5, the abdomen with more accurate visceral fat and subcutaneous fat calculation formula It is to provide an obesity analysis apparatus and method.

Another technical problem to be achieved by the present invention is to show the abdominal circumference and the area of subcutaneous fat and visceral fat constituting the abdomen, and the subject can easily distinguish whether the detailed cause of abdominal obesity is in visceral fat or subcutaneous fat. It is to provide an obesity analysis apparatus and method.

Hereinafter, the configuration and operation of an abdominal obesity analysis apparatus and method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 4 is a simplified block diagram of the configuration of the abdominal obesity analysis apparatus according to an embodiment of the present invention, the input unit 200, the control unit 210, AC current inlet 220, measuring unit 230, electrode The unit 240 includes a voltage detector 250, an operation processor 260, a display unit 270, and a storage unit 280.

The input unit 200 receives environment setting information such as information on an examinee (ID, height, weight, age, gender, test date, etc.), display unit control information, and measurement site selection control information, and the controller 210 ), And transmits it to the calculation processing unit 260.

The control unit 210 generates an AC constant current control signal from the measurement site selection control information received from the input unit 200 and outputs the AC constant current control signal to the AC current inlet unit 220.

The AC current inlet 220 includes a sinusoidal wave generator (not shown), a feedback type constant current generator (not shown), and the like, and generates and measures AC constant current according to an AC constant current control signal received from the controller 210. Output to the unit 230.

The sinusoidal wave generator (not shown) generates a sinusoidal wave having a frequency between 1 kHz and 1 Mhz by the AC constant current control signal received from the controller 210. In the present invention, by using the multi-frequency of 1kHz ~ 1Mhz can measure the amount of intracellular / external fluid as well as the amount of water throughout the body. In other words, most conventional body composition analyzers use an alternating current of 50 kHz, which flows through most of the extracellular fluid components, and some current flows into the cells. Low frequencies (1 kHz to 5 kHz) cannot pass through the cell due to the inherent capacitive properties of the cell membrane, so impedance is only affected by extracellular fluid components, while high-frequency (100 kHz to 500 kHZ) currents pass through the cell membrane and intracellular fluid components The impedance is measured by the sum of the extracellular fluid components. Therefore, the present invention makes it possible to measure the amount of intracellular / external fluid as well as the amount of water throughout the body using multiple frequencies of 1kHz-1Mhz.

The feedback constant current generator (not shown) uses a current that is currently drawn to draw a constant current of 450 uA or less into the measurement unit 230 regardless of load in a frequency range of 1 kHz to 1 MHz used for measuring the impedance. It is configured to monitor and compensate for this. This compensates the current according to the load change caused by the change of the measurement site from the current generated through the sinusoidal wave generator (not shown) according to the signal received from the control unit 210 to provide a constant constant current to the measurement unit 230. It is to draw in.

The measuring unit 230 includes a current electrode unit (not shown). The measuring unit 230 outputs a current drawn from the AC current inlet unit 220 to the current electrode unit in the selected measurement unit. A belt electrode can be used as the electrode attached to the abdomen. The electrode is positioned to measure the impedance of the abdominal cross section between lumbar spine 4-5.

The voltage detection unit 250 includes a voltage electrode unit (not shown), and sends a current from the AC current inlet unit 220 to the current electrode unit of the measuring unit 230 and transmits a current through the voltage electrode unit (not shown). ). The detected voltage is a body measurement signal, which is a voltage signal having body body impedance information. The voltage signal having the body impedance information thus detected is converted into an analog signal through an A / D converter (not shown) and then transmitted to the operation processor 260.

The calculation processor 260 calculates abdominal visceral fat and subcutaneous fat area by using the output signal of the voltage detector 250.

The display unit 270 displays an output signal of the arithmetic processing unit 260 and includes a display unit 272 and a printer unit 277.

The display unit 272 displays the analysis result output from the calculation processing unit on the screen. Since the display unit 272 is provided with an environment in which the user can exchange information through a graphic using a graphical user interface (GUI), the user can perform a task using only the mouse.

The printer unit 277 prints the analysis result outputted from the calculation processing unit.

The storage unit 280 stores the input items and the computed results, and when the test is performed one or more times, the previous test result may be stored and compared with the current test result.

The process of calculating the abdominal visceral fat and subcutaneous fat area by the calculation processing unit 260 is as follows. In the present invention, the impedance (Ztrunk) of the torso as shown in FIG. Use a regression equation. The impedance of the abdominal cross section between lumbar spine 4 and 5 is used because the abdominal region that best reflects abdominal obesity is between lumbar spine 4 and 5.

Visceral FAT Area is calculated by Equation 1.

Visceral Fat Area = C ₁ + (C ₂ × Age) + (C ₃ × Wt) + (C ₄ × Ht ² / Zt)

Where C ₁ to C ₄ are appropriate constants, Age is age, Wt is weight, Ht is height, and Zt is trunk impedance.

Subcutaneous FAT Area is calculated as in Equation 2.

Subcutaneous area = D ₁ + (D ₂ × Age) + (D ₃ × Ht) + (D ₄ × Wt) + (D5 × Ht ² / Zt)

Where D ₁ ~ D ₅ are the appropriate constants, Age is the age, Wt is the weight, Ht is the height, and Zt is the body impedance.

In equations (1) and (2), the constants C and D are the constants that best satisfy the equation, and cross the level of lumbar spine 4-5 using CT (computer tomography), Hounsfield number -250 The total abdominal fat area is measured by measuring the area belonging to -50, and the inside is the visceral fat tissue and the outside is subcutaneous. It is determined by regression analysis using abdominal viscera and subcutaneous fat area.

5A is an example of an electrode used in the measuring unit of FIG. 4, and FIG. 5B is an explanatory diagram of a body impedance when the electrode of FIG. 5A is worn. 5A and 5B illustrate the belt electrode.

The belt 20 includes a velcro 25, a connection part 27, and an electrode part 240.

The Velcro 25 serves to adjust the belt to fit its body so that the electrode part 240 is mounted.

The connection part 27 connects each of the electrode part 240 and the main body of the abdominal obesity analysis device to transmit and receive each signal.

The electrode part 240 includes a current electrode part 242 and a voltage electrode part 247, and a total of four parts are positioned at predetermined intervals. The current electrode unit 242 is an electrode for introducing a current, and the high voltage electrode unit 247 is an electrode for measuring a voltage, thereby introducing a current into each position and measuring a voltage at that position. As shown in FIG. 5B, the current electrode parts 242 and the voltage electrode parts 247 are located at the middle part of the front part of the ship, the middle part of the back, and the left and right flanks, and each of the six impedances (seg1, seg2, seg3, seg4, seg5, seg6) can be obtained. In the case of using the existing chamber impedance, the degree of abdominal obesity was estimated only by the impedances of the legs, arms, and torso, but this was not an accurate measure that distinguished visceral fat from subcutaneous fat. Therefore, the present invention calculates the degree of abdominal obesity by measuring the correlation between fat mass and impedance by acquiring the impedance of the abdomen through various paths, for which six electrodes are attached. In addition, the spacing and position between the electrodes greatly influence the measurement results. The electrodes were included in the belt to maintain a constant position and spacing as shown in Fig. 5b, making it easy to place the electrodes in the same position at all times during multiple measurements.

FIG. 6A is an example of an abdominal obesity analysis result shown in the display unit of FIG. 4, wherein the subject information item 400, the body composition analysis item 410, the muscle / body fat balance item 420, the body composition distribution analysis item 430 for each part, Body evaluation items 440, abdominal obesity analysis items 450, comprehensive evaluation items 460 are included.

The subject information item 400 includes an ID, name, age, gender, height, test date, and a previous test date which is the most recent test date of the test subject stored in the storage unit 280 when the testee is inspected more than once. Is displayed. The test date indicates not only the date but also the test time so that it can be distinguished when measuring several times a day.

The body composition analysis item 410 not only compares the present and previous measurement values of body water, protein, minerals and body fat at the same time, but also compares them in a cylindrical graph to express the percentage of each component in the total body composition. In addition, the results of the body composition analysis can be more easily understood.

The muscle / body fat balance item 420 represents a degree in a bar graph by dividing each measurement of weight, muscle mass, body fat mass, body fat percentage, extracellular fluid ratio, substandard, standard, and above standard. At this time, the bar graph shows the current value and the previous value at the same time so that it is easy to check whether the current muscle and body fat are better managed / maintained than before. The current and previous bar graphs distinguish their colors to make them more distinct. Considering the difference in body fat between men and women, the percentage of body fat appears below the standard, standard, and above.

The body composition distribution analysis item 430 for each part indicates the distribution of body fat and muscle for each part by ellipses of arms, legs, and torso, respectively, and shows the standard values of body fat and muscle of each part and the current and previous values in different colors. Expressed to the extent of being able to see at a glance. This consists of ellipses for each part of what was shown only in the conventional bar graph, it is possible to more easily understand the analysis results of the body composition distribution for each part.

The body shape evaluation item 440 places four points of body fat, weight, muscle, and abdominal fat percentage in the corresponding areas of body fat, weight, muscle, and abdominal fat percentage in three round areas, and then connects each point to form a quadrangular shape. The green section in the middle of the round 3 area corresponds to the standard, and the closer the square is to the square, the more the standard body shape becomes. If the square is skewed to a point, it means that the body composition is much distributed. Each of the four points can express their current and previous points at the same time to compare their previous and present body types, so that they can check whether they have been well managed. In addition, the body mass index (BMI) is used to express one's current and previous body shape by dividing it into eight body types, including obesity, obesity, standard obesity, normal, low body weight, overweight, low fat, and muscle mass. The subject makes it easy to make judgments about body type maintenance.

The abdominal obesity analysis item 450 is an item expressing an analysis result for abdominal obesity. In this section, three abdominal cross-sections for abdominal obesity are divided into three categories: abdominal obesity, above, standard, and below standard. Different sizes are used to suggest abdominal obesity. This makes it easy to determine whether your abdominal obesity is caused by subcutaneous fat or visceral fat. You can find out more about whether your location is above the standard, the standard, or the standard by the bar graph next to the cross section. Since there is a difference in the amount of fat in men and women, the standard range is different and the reference values are written on different axes. In men, the Visceral fat-Subcutaneous fat ratio (hereinafter referred to as VSR) is in the standard range of 0.8 to 0.9, and in women, the VSR ranges from 0.75 to 0.85. The standard range fills the background in green to indicate the boundary between the substandard and substandard ranges. It also shows the WHI (Women Health Initiative), abdominal obesity rate, subcutaneous area, visceral fat area, abdominal fat area, previous and current measurements of VSR, and expresses previous and current changes. This will allow you to see your abdominal obesity and to see how your figure changes to make sure you're well-maintained. In addition, the current and previous positions of the subcutaneous fat and visceral fat types are represented by different shaped dots, indicating that the two types of abdominal obesity and obesity are subcutaneous and visceral fat. The location of the abdomen can be easily distinguished between visceral fat and subcutaneous fat.

The comprehensive evaluation item 460 indicates weight control, body balance, and body development index. The weight control section tells you the optimal weight and tells you how much muscle mass and fat you need to adjust to get the optimal weight. The body balance section suggests proper exercise direction and diet control. Body development index indicates the development of body shape based on muscle mass and body fat mass. The more muscle mass, the larger the number of filled stars. This allows the subject to make judgments regarding the management of muscle mass and body fat mass.
