Acetone is known to be released from the body as a biogas through lungs, skin, mucous membranes and the like after being released into the blood by metabolism. Therefore, it can be said that measuring the acetone concentration in the biogas is useful for grasping the burning state of body fat. It is known that there is a correlation between the acetone concentration of exhaled gas and the concentration of acetone in skin gas (for example, C.CTurner et al., Rapid Communications in Mass Spectrometry, vol.22, pp.526 -532, 2008).

An experiment was conducted in which the amount of activity was recorded over 60 days. In addition, although the measurement of the acetone concentration of the expiration gas may be performed at an arbitrary timing, it is most preferable to be performed immediately after getting up and before breakfast. In addition, during the experimental period, the subject calculated calorie intake by recording all the contents and amount of food and drink, and calorie consumption by constantly carrying an activity meter.

Specifically, the calculation unit 16 calculates correlation data corresponding to the user based on the acetone concentration and the calorie balance actually measured over a predetermined period for the specific user. For example, the user records the acetone concentration and the calorie balance for about one week and uses this as the learning period.

- the correction unit 17 is a means for calculating the correlation between the acetone concentration and the calorie balance. Specifically, the correction unit 17 corrects the correlation data obtained in advance based on the measured values of acetone concentration and calorie balance. For example, the correction unit 17 may correct the intercept of the calibration curve based on the actual measurement value without changing the slope of the calibration curve, or may correct the slope of the calibration curve.
- the correction may be to prepare correlation data for each user and correct each correlation data based on the actual measurement value of each user, or prepare common correlation data for each user.
- the correlation data may be corrected based on the actual measurement values of all users.
- the correction unit 17 may perform correction using information other than the acetone concentration. Specifically, the correction unit 17 can correct the correlation data using the user data described above. For example, a diabetic patient tends to have a higher acetone concentration of exhaled gas, and thus the tendency may be different from a general calibration curve (that is, a calibration curve of a person who is not a diabetic patient). In such a case, the correction unit 17 can determine the presence / absence of diabetes and the degree of progression with reference to a blood glucose level or an electronic medical record in the user data, and can correct the calibration curve according to the determination result. is there. Alternatively, the correction unit 17 may correct the calibration curve based on the user's BMI. This is because the higher the BMI, the more difficult the acetone is discharged. Thus, various data can be considered as parameters used for correction by the correction unit 17.
- the timing of measuring acetone is preferably immediately after getting up, but may be measured at other timings. For example, when waking up in the morning and measuring in the evening, the calorie balance from the time of the measurement in the evening to about 24 hours ago is directly substituted into the calibration curve indicating the correlation between the acetone concentration and the calorie balance. May be estimated.
- the acetone concentration value measured in the evening is a value at a predetermined time (for example, immediately after getting up).
- the conversion value may be substituted into a calibration curve indicating the correlation between the acetone concentration and the calorie balance, and the calorie balance for one day starting from the predetermined time point may be estimated and obtained.
- a calorie balance based on a predetermined time, that is, a fixed time.
- “one day” does not have to be exactly 24 hours, and may be expressed in round numbers by rounding (or rounding up or down) the minute unit, for example.
- the calorie intake or calorie consumption can be estimated.
- the calorie intake or calorie consumption can be estimated. For example, when the user measures the acetone concentration and records the calorie consumption, it is possible to estimate (inversely calculate) the calorie intake based on the estimated calorie balance and the calorie consumption.
- the calorie consumption can be estimated based on the estimated calorie balance and the calorie intake. In this way, it is possible to estimate the calorie consumption even if the user does not carry an activity meter or the like, or to estimate the calorie intake even if the user does not record the contents of the meal.
- the calorie management system 10 may notify the estimation result to a user different from the user who measured the acetone concentration.
- the calorie management system 10 can also notify the estimation result to other users who have a specific relationship (such as parent and child) with the user who is the subject. That is, in the present invention, the user who is the subject and the user who is the notification target are not necessarily the same.
- the configuration for carrying out the present invention is not limited to the configuration shown in FIG.
- the present invention can be implemented by an apparatus in which a function corresponding to the measurement apparatus 100 and a function corresponding to the calculation apparatus 200 are integrated without being separated. In this way, it is not necessary to transmit / receive data via the network.
- the computing device 200 may be configured such that the configuration corresponding to the sensor unit 120 is configured separately from the other configurations and exchanges data with each other by wired or wireless communication.
- the system of the present invention is based on the acquisition unit that acquires the concentration of acetone contained in the gas component released from the user and the predetermined correlation between the acetone concentration and the calorie balance. What is necessary is just to provide the estimation part which estimates the calorie balance corresponding to a density
- the present invention provides a calorie management system including the information processing apparatus, a program for causing a computer (CPU or the like) to function as the information processing apparatus, and a calorie balance estimation method. It can also be provided in the form of The program can also be provided in a form recorded on a recording medium such as an optical disk, or in a form that can be downloaded to a predetermined device via a network such as the Internet and used by installing the program.

本発明の主たる特徴は、人体から放出される気体に含まれるアセトンの濃度(以下単に「アセトン濃度」ともいう。)に基づいてカロリー収支を推定する点にある。本発明の発明者らは、カロリー収支の管理を容易にするという課題を解決するための手段を検討した結果、アセトン濃度とカロリー収支との間に相関関係があることを発見した。ここにおいて、人体から放出される気体とは、皮膚又は粘膜から発せられるガスや呼気を含み、生体ガスなどともいう。
図2は、本発明の一実施例に係るカロリー管理システム10の構成を示すブロック図である。カロリー管理システム10は、測定装置100と、計算装置200とを備え、これらをネットワーク300を介して互いに接続した構成を有するシステムである。測定装置100は、ユーザから放出される生体ガスのアセトン濃度を測定するための装置である。また、計算装置200は、生体ガスのアセトン濃度とカロリー収支の相関関係に基づいてカロリー収支を推定するための装置である。ネットワーク300は、測定装置100と計算装置200との間でデータを送受信するための通信ネットワークであり、インターネットや移動体通信網を含み得る。
性のメモリとを備え、所定のプログラムを実行することによって測定装置100の各部の動作を制御する。
活動量、基礎代謝、血糖値、HbA1c値などを含んでもよく、さらには電子スケジューラに登録されたユーザの予定や飲食及び運動の履歴(すなわちカロリーの摂取及び消費の履歴)を含んでもよい。また、ユーザの既往歴などの医療情報が電子データ(いわゆる電子カルテ)として入手可能である場合には、これをユーザデータに含んでもよい。
なお、相関データは、後述するようにユーザ毎に異なっていてもよい。この場合、相関データは、ユーザデータの一部としてもよい。
上述した実施例は、本発明の実施の一態様である。本発明は、この実施例の態様に限らず、以下に示す他の態様でも実施することが可能である。なお、以下に示す変形例は、必要に応じて、各々を組み合わせることも可能である。
要するに、本発明のシステムは、ユーザから放出されたガス成分に含まれるアセトンの濃度を取得する取得部と、予め定められた、アセトン濃度とカロリー収支との相関関係に基づき、前記取得されたアセトン濃度に対応するカロリー収支を推定する推定部と、前記推定の結果を用いて所定の処理を実行する処理実行部とを備えていればよい。
