データ取得部21は、唾液中の成分または物性を唾液測定器で測定して得られた、1種または2種以上の成分または物性の唾液データを取得する。データ取得部21は、唾液測定器1からの出力データを直接取得するように、当該唾液測定器と電気的に接続可能な入力インターフェースを有する。   The data acquisition unit 21 acquires saliva data of one type or two or more types of components or physical properties obtained by measuring components or physical properties in saliva with a saliva measuring device. The data acquisition unit 21 has an input interface that can be electrically connected to the saliva measuring instrument so as to directly acquire output data from the saliva measuring instrument 1.

唾液測定器1としては、例えば、pH測定器、アミラーゼ測定器、粘度計、唾液量測定器、IgA測定器、酸化還元電位測定器、コルチゾール測定器、クロモグラニンA測定器などが挙げられる。唾液測定器は、上記各種測定器の内2種以上が一体となったデバイス、測定キットとして構成されていてもよい。   Examples of the saliva measuring instrument 1 include a pH measuring instrument, an amylase measuring instrument, a viscometer, a saliva measuring instrument, an IgA measuring instrument, an oxidation-reduction potential measuring instrument, a cortisol measuring instrument, and a chromogranin A measuring instrument. The saliva measuring device may be configured as a device or a measuring kit in which two or more of the various measuring devices are integrated.

相関データ格納部221は、唾液中に含まれる1種または2種以上の成分または物性と、血液を測定して得られた1種または2種以上の成分との間の相関関係に関する相関データを予め格納している。   The correlation data storage unit 221 stores correlation data regarding the correlation between one or more components or physical properties contained in saliva and one or more components obtained by measuring blood. Stored in advance.

唾液中の成分または物性(唾液の検査成分)は、例えば、pH,アミラーゼ、IgA、酸化還元電位、唾液自体の粘度、唾液量、コルチゾール、クロモグラニンA(CgA)などが挙げられる。   Examples of saliva components or physical properties (saliva test components) include pH, amylase, IgA, redox potential, saliva viscosity, saliva volume, cortisol, chromogranin A (CgA), and the like.

相関データは、例えば、唾液のアミラーゼと血液のトリグリセライド、唾液のIgAと血液の尿酸、唾液のpHと血液のトリグリセライド、唾液のアミラーゼと血圧が挙げられる。相関データ格納部221に格納されている相関データの一例としては、唾液の各成分の数値に対する生活習慣病の種類、その程度(重篤度)(例えば、正常、予備軍、精密検査必要、経過観察、生活習慣病の可能性が低、中、高など)などの判定結果を有する。また、相関データには、測定者個人の唾液特性が考慮されている方が望ましい。(唾液は個人差が大きいため)さらに、相関データには、血液に関する各種データが生活習慣病に関連付けられて含まれていてもよい。唾液と血液との相関関係については、後述する。   Examples of the correlation data include salivary amylase and blood triglyceride, salivary IgA and blood uric acid, saliva pH and blood triglyceride, salivary amylase and blood pressure. As an example of the correlation data stored in the correlation data storage unit 221, the type and severity (severity) of lifestyle-related diseases with respect to the numerical values of each component of saliva (for example, normal, reserve army, close work required, progress Observation, possibility of lifestyle-related diseases is low, medium, high, etc.). In addition, it is desirable that the saliva characteristics of the individual measurer be considered in the correlation data. (Since saliva has a large individual difference) Furthermore, the correlation data may include various data related to blood in association with lifestyle-related diseases. The correlation between saliva and blood will be described later.

また、相関データは、唾液の成分(または物性)同士の相関関係のデータを含み、例えば、IgAとpH、IgAとアミラーゼなどの相関関係のデータが挙げられる。   The correlation data includes correlation data between saliva components (or physical properties), and examples include correlation data such as IgA and pH, and IgA and amylase.

判定部22は、データ取得部21で取得した唾液データと、相関データ格納部221に格納されている相関データに基づいて、生活習慣病を判定する。判定部22は、予め設定されている相関データと唾液データとから生活習慣病を判定する。   The determination unit 22 determines lifestyle-related diseases based on the saliva data acquired by the data acquisition unit 21 and the correlation data stored in the correlation data storage unit 221. The determination unit 22 determines lifestyle-related diseases from preset correlation data and saliva data.

判定部22は、例えば、回帰分析における回帰線(相関データの一種)と唾液データとを比較し、重篤度を判定する。唾液データ(例えば、アミラーゼ)が回帰線(アミラーゼとトリグリセライドとの相関データ)から10%未満の範囲に入っていれば、「生活習慣病(例えば高脂血症)の可能性が高い」と判定し、唾液データが回帰線から10%以上20%未満の範囲内に入っていれば、「生活習慣病(例えば高脂血症)の可能性が中程度」と判定し、唾液データが回帰線から20%以上30%未満の範囲内に入っていれば、「生活習慣病(例えば高脂血症)の可能性が低い」と判定するように構成できる。また、判定部22は、他の判定手法を取ることもできる。   For example, the determination unit 22 compares the regression line (a kind of correlation data) in the regression analysis with saliva data to determine the severity. If saliva data (for example, amylase) is within a range of less than 10% from the regression line (correlation data between amylase and triglyceride), it is determined that there is a high possibility of lifestyle-related diseases (for example, hyperlipidemia) If the saliva data is within the range of 10% or more and less than 20% from the regression line, it is determined that the possibility of lifestyle-related diseases (for example, hyperlipidemia) is moderate, and the saliva data is the regression line. If it falls within the range of 20% or more and less than 30%, it can be configured to determine that “the possibility of lifestyle-related diseases (for example, hyperlipidemia) is low”. Moreover, the determination part 22 can also take another determination method.

管理部222は、管理データを保存する。管理データは、少なくとも判定部22で判定された生活習慣病を前記唾液データとが関連づけられている。また、管理部222は、管理データとして、ユーザ情報(氏名、年齢、性別、病歴など)と、唾液データ(検査日、データ取得日、検査値など)、判定結果(生活習慣病とその程度、ストレスとその程度)などを関連付けて保存することが好ましい。   The management unit 222 stores management data. In the management data, at least lifestyle-related diseases determined by the determination unit 22 are associated with the saliva data. In addition, the management unit 222 includes, as management data, user information (name, age, sex, medical history, etc.), saliva data (examination date, data acquisition date, examination value, etc.), determination result (lifestyle related disease and its degree, It is preferable to store the stress and its degree) in association with each other.

(Management, support for meals, exercise and rest)
When an abnormal value (other than normal value) is determined for hyperlipidemia, depending on the degree, the intake of animal fat (in the direction of reduction), the intake of cholesterol food (in the direction of reduction), dietary fiber Provide advice and support regarding dietary intake (increase direction) and vitamin intake (increase direction). If gout is determined to be an abnormal value (other than normal), depending on the degree, diet such as water intake (increase direction), salt intake (increase direction), alcohol intake (increase direction), etc. Provide advice and support. For exercise and rest, advice and support are provided according to the degree of each abnormal value.

管理部222は、判定結果に応じて、上記食事、運動、休養などのアドバイス(あるいは支援内容)も管理データとして含んでいる。これによって、後述する出力部23によって管理データが情報処理装置へ出力されて、ユーザが確認できるようになる。ユーザは、判定結果と上記アドバイス・支援を簡便に確認できる。   The management unit 222 also includes advice (or support content) such as the meal, exercise, and rest as management data according to the determination result. As a result, the management data is output to the information processing apparatus by the output unit 23 to be described later, so that the user can check. The user can easily confirm the determination result and the advice / support.

出力部23は、管理部222で保存されている管理データを(外部の)情報処理装置3へ出力する。出力部23が、無線方式でデータを情報処理装置3へ出力することが好ましい。無線方式としては、例えば、短距離通信、Bluetooth(商標登録)などが挙げられる。また、有線方式の場合には、専用回線、USB通信、RS−232C等が挙げられる。   The output unit 23 outputs the management data stored in the management unit 222 to the (external) information processing apparatus 3.

(Embodiment 2)
The lifestyle-related disease determination support system includes a smartphone or tablet terminal that transmits and receives data wirelessly between the lifestyle-related disease determination support device of Embodiment 1 and an output unit that configures the lifestyle-related disease determination support device. A smartphone or the like can be configured to install a dedicated application in advance, start the dedicated application, automatically communicate with the lifestyle-related disease determination support device, and receive management data. The received management data is displayed on the display screen. Use of a smartphone or tablet terminal is preferable because management and determination support such as lifestyle-related diseases and stress can be easily performed at home.

本実施形態1,2では、pHまたはアミラーゼから高脂血症を判定できる。また、pHとアミラーゼに基づいて同じ高脂血症を判定できるが、いずれか一方の指標でのみ高脂血症が判定された場合には、低いレベルで高脂血症性であると判定され、両指標で高脂血症が判定された場合には、高いレベルで高脂血症性であると判定することができる。すなわち、異なる2指標を用いて段階的に判定をすることができる。   In the first and second embodiments, hyperlipidemia can be determined from pH or amylase. In addition, the same hyperlipidemia can be determined based on pH and amylase, but if hyperlipidemia is determined only by one of the indicators, it is determined to be hyperlipidemic at a low level. When hyperlipidemia is determined by both indices, it can be determined that the hyperlipidemia is at a high level. That is, the determination can be made step by step using two different indexes.

また、IgAから通風が判定でき、アミラーゼから高血圧であるか否かを判定できる。   Moreover, ventilation can be determined from IgA, and it can be determined from amylase whether it is hypertension.

また、pHとIgAあるいはアミラーゼとIgAの相関関係から、pHまたはアミラーゼに基づいて通風を判定できる。また、pHまたはアミラーゼに基づいて(IgAとの相関関係を介して)同じ痛風が判定できるが、いずれか一方の指標でのみ通風が判定された場合には、低いレベルで通風であると判定され、両指標で痛風が判定された場合には、高いレベルで通風であると判定することができる。これによればIgAの測定をすることなく、通風を判定できる。   Further, ventilation can be determined based on pH or amylase from the correlation between pH and IgA or amylase and IgA. The same gout can be determined based on pH or amylase (via correlation with IgA), but if ventilation is determined only with one of the indicators, it is determined that the ventilation is at a low level. When gout is determined by both indicators, it can be determined that the ventilation is at a high level. According to this, ventilation can be determined without measuring IgA.

また、pHとIgAあるいはアミラーゼとIgAの相関関係から、IgAからも高脂血症を判定できる。すなわち、3指標に基づいて高脂血症を判定することができる。   Hyperlipidemia can also be determined from IgA based on the correlation between pH and IgA or amylase and IgA. That is, hyperlipidemia can be determined based on the three indices.

以上本実施形態1,2によれば、血液検査によらず、唾液に関する測定結果と、予め求められている血液と唾液との相関関係から、生活習慣病を簡単に判定できる。   As described above, according to the first and second embodiments, lifestyle-related diseases can be easily determined from the measurement result related to saliva and the correlation between blood and saliva obtained in advance, regardless of blood tests.

以上実施形態1,2では、生活習慣病の判定について説明したが、本発明はこれに制限されず、例えば、唾液自体の粘度、コルチゾールまたはクロモグラニンA(CgA)と血液成分(血圧を含む)との相関データと唾液データとを比較してストレス判定を行うこともできる。   In Embodiments 1 and 2 described above, the determination of lifestyle-related diseases has been described. However, the present invention is not limited to this. For example, the viscosity of saliva itself, cortisol or chromogranin A (CgA) and blood components (including blood pressure) It is also possible to make a stress determination by comparing the correlation data with saliva data.

<唾液と血液の相関関係の構築>
まず、唾液と血液の相関関係を構築する。本発明は、以下で求められる相関データ(相関関係、相関係数)に限定されない。唾液提供者から健康診断データ、問診データを得た。血液サンプルと各種測定値は、健康診断の測定値を利用する。唾液の採取方法は以下の通りである。まず、昼食後に歯磨きをし、その後2時間後の15時に唾液サンプルを採取する。これを、5日間連続で行う。
<Construction of correlation between saliva and blood>
First, the correlation between saliva and blood is constructed. The present invention is not limited to the correlation data (correlation, correlation coefficient) obtained below. Medical examination data and interview data were obtained from saliva providers. The blood sample and various measurement values use the measurement values of the health checkup. The method for collecting saliva is as follows. First, brush your teeth after lunch, then take a saliva sample at 15:00, 2 hours later. This is done for 5 consecutive days.

(唾液検査)
採取した唾液サンプルの測定を行う。pH測定は、各種pH測定器を用いることができ、例えば堀場製作所製の「Twin pH」が挙げられる。また、アミラーゼ測定は、各種アミラーゼ測定器を用いることができ、例えば二プロ製「唾液アミラーゼモニター」が挙げられる。IgA測定は、ELISA法による唾液中に含まれる抗体あるいは抗原の濃度を定量検出する。ELISA法は一般的な手法である。唾液サンプルは、上記採取方法で24名から5日間採取する。極端に外れたデータは用いないものとできる。表1に5日間唾液サンプルの平均pH、平均アミラーゼ値、平均IgA値を示す。空欄は唾液サンプル量が少なく測定できなかったためである。
(Saliva test)
The collected saliva sample is measured. Various pH measuring devices can be used for pH measurement, and examples thereof include “Twin pH” manufactured by Horiba. In addition, various amylase measuring instruments can be used for amylase measurement, for example, Nipro's “saliva amylase monitor”. In IgA measurement, the concentration of antibody or antigen contained in saliva by ELISA is quantitatively detected. The ELISA method is a general method. Saliva samples are collected for 5 days from 24 people by the above collection method. Extremely deviating data can not be used. Table 1 shows the average pH, average amylase value, and average IgA value of the 5-day saliva sample. This is because the amount of saliva sample was small and could not be measured.

Figure 2014130096
Figure 2014130096

(唾液検査結果と血液検査結果との相関関係)
まず、唾液サンプル全体(5日間平均値)についてピアソン相関係数の検定を行う。2変量の間の関連度合いを測る指標である相関係数を求め、相関係数の有意性を検定する。つまり、母相関係数ρ=0を検定することで帰無仮説:「2変量の間に相関はない」を検定する。また、母相関係数ρの100(1−α)%信頼区間を表示し、ρの信頼区間に0が含まれないとき、ρ≒0を意味し、すなわち検定は有意であり、2変量の間に相関があるとみることができる。ここでは、具体的には相関関係の結果と判定は、相関係数を算出し、P値を算出し、信頼区間を算出する。P値において危険率5%以内であれば相関有意性があると判定する。
(Correlation between saliva test results and blood test results)
First, the Pearson correlation coefficient is tested for the entire saliva sample (average value over 5 days). A correlation coefficient that is an index for measuring the degree of association between two variables is obtained, and the significance of the correlation coefficient is tested. That is, the null hypothesis: “no correlation between two variables” is tested by testing the population correlation coefficient ρ = 0. Also, the 100 (1-α)% confidence interval of the population correlation coefficient ρ is displayed, and when 0 is not included in the confidence interval of ρ, it means that ρ≈0, that is, the test is significant, and the bivariate It can be seen that there is a correlation between them. Specifically, in the correlation result and determination, a correlation coefficient is calculated, a P value is calculated, and a confidence interval is calculated. If the risk value is within 5% in the P value, it is determined that there is a correlation significance.

表2に有意な相関関係が認められた、pHとトリグリセライド、アミラーゼと血圧(上の値)、アミラーゼとトリグリセライド、IgAと尿酸の各データを示す。   Table 2 shows data of pH and triglyceride, amylase and blood pressure (upper value), amylase and triglyceride, IgA and uric acid, in which a significant correlation was recognized.

表4は、pHが高群の人のIgAと尿酸値の相関、アミラーゼが低群の人のIgAと尿酸値の相関、酸化還元電位が低群の人のIgAと尿酸値の相関、血糖値が低群の人のIgAと尿酸値の相関を示している。それぞれの指標の全データの平均値を境に高群と低群とに分けた。pHの高群において、IgAと尿酸との相関係数が「−0.866」と絶対値が1に近づき、その高群において低群よりも高い相関が認められた。また、アミラーゼの低群において、IgAと尿酸との相関係数が「−0.941」と絶対値が1に近づき、その低群において高群よりも高い相関が認められた。また、血液サンプル全体の血糖値の平均値を境に高群と低群とに分け、血糖値の高群において、IgAと尿酸との相関係数が「−0.843」と絶対値が1に近づき、その高群において低群よりも高い相関が認められた。また、唾液サンプル全体の酸化還元電位の平均値を境に高群と低群とに分け、酸化還元電位の低群において、IgAと尿酸との相関係数が「−0.979」と絶対値が1に近づき、その低群において高群よりも高い相関が認められた。なお、酸化還元電位は、塩化銀電極(基準極)と白金電極(作用極)による電気化学測定法によって測定される。   Table 4 shows the correlation between IgA and uric acid levels in people with high pH, correlation between IgA and uric acid levels in people with low amylase, correlation between IgA and uric acid levels in people with low redox potential, blood glucose levels Shows the correlation between IgA and uric acid levels in the low group. The average value of all data of each index was divided into high group and low group on the boundary. In the high pH group, the correlation coefficient between IgA and uric acid was “−0.866”, and the absolute value approached 1, and a higher correlation was observed in the high group than in the low group. In the low group of amylase, the correlation coefficient between IgA and uric acid was “−0.941” and the absolute value approached 1, and a higher correlation was observed in the low group than in the high group. In addition, the blood glucose level is divided into a high group and a low group on the basis of the average blood glucose level of the whole blood sample. In the high blood glucose group, the correlation coefficient between IgA and uric acid is “−0.843” and the absolute value is 1. The higher group showed a higher correlation than the lower group. In addition, the average value of the redox potential of the whole saliva sample is divided into a high group and a low group, and in the low group of the redox potential, the correlation coefficient between IgA and uric acid is “−0.979” and an absolute value. Was close to 1, and a higher correlation was observed in the low group than in the high group. The oxidation-reduction potential is measured by an electrochemical measurement method using a silver chloride electrode (reference electrode) and a platinum electrode (working electrode).
