Description

  The present invention relates to a meal guidance support apparatus that supports appropriate meal guidance by an expert such as a registered dietitian to a target user who needs meal guidance, and in particular, the guidance content can be relaxed according to the behavior change phase of the target user. The present invention relates to a meal guidance support device.

  Lifestyle-related diseases such as diabetes and hypertension are caused by lifestyle habits such as eating habits, and the improvement of lifestyle habits is required for the treatment. It is common for standard diet therapy to receive appropriate dietary guidance from experts, learn appropriate dietary management methods, and eventually continue “self-management” to properly manage meal content on their own .

  In dietary guidance to shift to self-management, providing a specific method for improving lifestyle habits is an important factor for encouraging users to undergo behavioral changes. Here, behavioral change means changing a habitual behavior pattern.

  Patent Document 1 discloses a method for calculating the amount of energy to be consumed by a user in a menu guidance system using a food exchange table in which foods are classified into a plurality of items by nutrients. Patent Document 2 discloses a system for customizing meal guidance based on medical examination information.

  Non-Patent Documents 1 and 2 show systems in which a user uploads a meal image to a server and an administrative dietitian provides guidance. Such a system has an advantage that the user can easily receive dietary guidance from a registered dietitian. Moreover, in such a system, in order to reduce the labor burden of the registered dietitian, comments and guidance are given after the meal photos are collected for about 3 days. Non-Patent Document 3 discloses a self-management type meal management system.

  As in Non-Patent Documents 1 and 2, a system in which a user uploads a meal image to a manager's server and a registered dietitian provides guidance has the advantage that the user can easily receive a dietary instruction from a registered dietitian . However, the prior art places importance on evaluating meal contents, and does not have a function that enables the user to confirm meal contents and encourage or communicate.

  In general, communication is required to increase the motivation of the subject regarding diet therapy. Motivation is likely to be maintained with regular encouragement from experts. Such interactive dietary guidance is particularly effective when teaching patients with different degrees of severity, such as diabetics.

  In order to obtain a high effect through interactive guidance, improvement is achieved by the expert correctly grasping the current behavior change phase (consciousness level) of the target person and giving the target person appropriate guidance according to that phase. It is necessary to promote behavioral change toward The following is an example of a behavioral transformation phase based on behavioral psychology.

(1) Indifference period: time when there is no intention to take action for behavior change within 6 months
(2) Period of interest: Time when there is an intention to take action for behavior change within 6 months
(3) Preparatory period: A period when there is a willingness to take action to change behavior within one month
(4) Execution period: When a clear behavioral change is observed, but the persistence is still less than 6 months
(5) Maintenance period: A period when a clear behavioral change is observed and that period lasts for more than 6 months

  Here, the literature (http://communicare.cocolog-nifty.com/suwa/2007/10/post_5a80.html) has the following description for each period.

  Period of interest: “A period when there is“ something ”or“ very ”interest in behavioral change. Finally, it is time to expect an effect from direct work through interviews. From this time on, it is especially important to establish a relationship of trust by listening to and accepting and empathizing while listening, and counseling skills are necessary for that purpose. It is a stage where there is interest but no intention to take action, and there are many anxieties about the behavior change itself and the burden associated with it. Therefore, it is important to have a proper understanding of the specific method and process of behavioral change, and to improve the self-efficacy that “I can do it”, and for that purpose, teaching as information provision is performed. In addition, for those who have time to spare and who are motivated to be with someone, it is also effective to invite them to group work aiming at the goal while supporting each other, and seeing and participating. "

  Preparatory period: “Not only do you have an interest in behavioral transformation, but you also want to take action for behavioral transformation” or “I want to do it immediately”. It is important to increase self-efficacy by having appropriate goals and action plans. For this purpose, coaching is performed, but if a person who is a beginner without basic knowledge and needs it, he / she also teaches with instructions and advice. Of course, other technologies such as teaching and group work as information provision should be used as appropriate. ''

  Execution period: “A clear change in behavior is observed, but there are“ very ”or“ somewhat ”concerns about future sustainability. Coaching will continue to increase self-efficacy and sustain. However, if you are a beginner without basic knowledge and need it, you will be taught by instructions and advice. Of course, other technologies such as teaching and group work as information provision should be used as appropriate. ''

  In this way, support for users who have advanced dietary guidance is relatively easy because it is only necessary to provide knowledge teaching as in the prior art, but it is encouraged to support users who are interested or in preparation. Therefore, it is not possible to expect a sufficient effect with the conventional technology.

  In Patent Literature 2, dietary guidance can be individualized, but general dietary guidance cannot reflect the preparation status or psychological state of the user's behavioral change, and thus is likely to reduce user motivation. . In other words, only users who are originally highly motivated can use them.

  In response to such technical issues, the inventors of the present invention can provide dietary guidance that can present information necessary for communication and information necessary for providing information to a dietitian who provides guidance according to the level of behavioral change of the user. A support system was invented and a patent application was filed (Patent Document 3).

  However, even if dietary guidance can be provided using such a system, patients with chronic diseases, typically represented by diabetics, go to where they are, where they are, and how Often people do not know what to eat.

  Moreover, even if the optimal management menu can be presented from general knowledge, “patients whose behavioral change has not progressed in particular” are often lacking in motivation, etc., and may be frustrated. Many.

  Furthermore, in non-patent literature, a home delivery service such as a lunch box is proposed, but the menu is fixed and often does not match the taste and eating habits of the person.

  The object of the present invention is to solve the problems of the prior art, change the tolerance for dietary restrictions according to the user's preference and the level of behavioral change, reduce the user's motivation, and maintain high efficiency with high continuity An object of the present invention is to provide a meal guidance support device capable of realizing meal guidance.

  In order to achieve the above object, the present invention is characterized in that a meal guidance support apparatus for proposing meal improvement to a user who is to receive meal guidance has the following configuration.

  (1) Meal log DB that accumulates meal logs of users, difference detection means that detects differences by comparing meal logs of target users with target meal contents, and meal restrictions based on behavior change phase of target users Tolerance determination means for determining the tolerance of the meal, and meal restriction determination means for proposing by relaxing the meal restriction that can eliminate the difference with the tolerance.

  (2) The difference detection means determines the target user who has succeeded in the meal instruction from the meal log DB, and adopts the meal log as the target meal content.

  (3) The difference detection means uses the contents of the meal when the target user is in the same phase as the behavior change phase of the target user as a comparison target.

  (4) It comprises means for clustering a user group based on the contents of the meal, and target user determining means for determining a user who belongs to the same cluster as the target user and succeeded in meal instruction as a target user.

  (5) A menu database for storing menus capable of realizing meal restrictions, and menu suggesting means for retrieving and proposing menus capable of realizing the proposed meal restrictions from the menu database.

  (6) Providing the target user of the current location with a means to acquire the current location information of the target user, a provider database that manages the menus and locations that the meal provider can provide, and a menu that can implement the proposed dietary restrictions And provider introduction means for searching for possible meal providers from the provider database and proposing them.

  (1) Realistic and persuasive power can be proposed to target users who need dietary guidance, because they can propose dietary restrictions based on the dietary content of the target user at the time who succeeded in dietary guidance and led to self-management. It is possible to have a meal instruction.

  (2) In the meal guidance that improves the difference between the target user's meal content and the target user's meal content, the lower the behavior change phase of the target user, the less the meal restrictions, the less the burden on the target user and the meal The continuity of instruction can be improved.

  (3) The group of users is clustered based on the meal content, and the meal restriction of the target user is determined based on the meal content of the target user at that time belonging to the same cluster as the target user and succeeded in the meal instruction. And dietary restrictions according to taste, and efficient and highly continuous dietary guidance.

  (4) Since a menu of dishes according to the determined meal restriction can be provided to the instructor or the target user, the target user can easily recognize a dish that meets the meal restriction and suits his / her preference.

  (5) Candidates and restaurants that can provide meals that meet meal restrictions can be presented according to the current location of the target user, and the target user can easily eat anytime and anywhere according to the contents of the meal restriction. Can be ingested.

It is a functional block diagram of the meal instruction assistance device concerning a 1st embodiment of the present invention. It is a figure for demonstrating the clustering method. It is the figure which showed the relationship between a subject user's action transformation phase and tolerance. It is a functional block diagram of the meal instruction assistance device concerning a 2nd embodiment of the present invention. It is the figure which expressed the function of the menu proposal part and menu DB typically. It is a functional block diagram of the meal instruction assistance device concerning a 3rd embodiment of the present invention. It is the figure which showed the correspondence of instruction | indication weight and the action change phase.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of a main part of a meal guidance support system to which the present invention is applied. A target user (for example, a diabetic patient or a hypertension patient) and a leader (for example, a registered dietitian) for dietary guidance are shown. Meal information is shared through the meal instruction support device 1 and the user terminal 2, and further information provision and communication are performed, whereby meal instruction by the instructor proceeds.

  The meal instruction support apparatus 1 associates meal information collected from the target user with identification information (user ID) and stores it as a meal log. Then, the meal log of the target user who succeeded in the meal instruction is compared with the meal log of the target user, and the meal instruction for eliminating the difference in the contents of the meals according to the stage of action change (behavior change phase) of the target user. Provide to each target user with ease.

  Such a meal guidance support device 1 can be configured by mounting an application (program) for realizing each function on a general-purpose computer or server. Alternatively, it can be configured as a dedicated machine or a single-function machine in which a part of the application is implemented in hardware or ROM.

[First embodiment]
FIG. 2 is a functional block diagram of the first embodiment of the present invention. In the meal log DB 20, the meal contents collected from the target users of the meal instruction via the interface 10 are associated with the behavior change phase of each user. Meal contents at that time collected from past users (target user candidates) who have already completed meal instruction and have been self-managed after being accumulated as meal logs are also accumulated as history information of meal logs for each behavior modification phase.

  In this embodiment, the behavior modification phase is divided into “indifference period”, “interest period”, “preparation period”, “execution period”, and “maintenance period”, and each target user and each target are referred to by referring to the meal log. It is possible to determine the content of meals that the user candidate ingested during each behavior modification phase.

  In the attribute DB 30, the current behavior modification phase is registered as attribute information of each target user together with age, gender, past illness and various gene information. The behavior modification phase of each target user may be judged subjectively by the administrator based on the meal contents and vital data of each user, or a prior application by the inventors of the present invention (Japanese Patent Application No. 2014-68534). It may be determined by the algorithm disclosed in (1).

  The difference detection unit 40 includes a nutrition balance calculation unit 401, a clustering unit 402, a target user determination unit 403, and a difference extraction unit 404, and compares the meal contents of the target user with the meal contents of the target user who has reached self-management. The difference between the two is detected.

  The nutrition balance calculation unit 401 calculates the nutrition balance of the target user based on the meal log, and further calculates a difference from the optimal balance. A diet balance guide or a food exchange table can be used as an indicator of nutrition balance. For example, in the meal balance guide, the optimum balance of staple foods, side dishes, main dishes, milk dairy products, and fruits is about 5-7, 5-6, 3-5, 2, 2, respectively (http: / /5aday.net/fact/p1/index.html), the sum of squares of the difference between these and the target user's nutritional balance can be taken as the difference from the optimal balance.

  The clustering unit 402 performs clustering by analyzing meal contents and attribute information taken during meal guidance for all users whose meal contents are stored in the meal log DB 20. In this embodiment, each user is clustered by generating a meal vector for each user based on the meal log and the like, and applying this to topic analysis (LDA: Latent Dirichlet Allocatoion). To do.

  At that time, as shown in FIG. 3, clustering is performed while changing the designation of the number of clusters n to be generated, and for each number n of clusters, a cross that gives a target user number with a large difference from the optimal balance and a small target user number Create a summary table and calculate its Akaike Information Criterion (AIC). Then, the number n of clusters in which the difference between the AIC when the independent model is assumed and the AIC when the dependent model is assumed is most determined.

  The target user determining unit 403 identifies a cluster to which the target user belongs based on the determined clustering result of the number n of clusters, and determines a target user candidate belonging to the cluster and having been self-managed as a target user. . This makes it possible to extract target users whose target users and meal tendencies, preferences, and attributes are similar.

  The difference extraction unit 404 refers to the meal log DB 20 and extracts the contents of the meal that the determined target user ingested during the same phase as the current behavior change phase of the target user. Differences in nutritional balance are extracted by comparing with meal contents.

  For example, if the target user's daily fruit intake is 100 grams, but the target user's current fruit intake is 60 grams, the shortage of “40 grams” regarding the fruit intake Are extracted as differences. This difference is that if the target user consumes more than 40 grams of fruit from the present time, it will be possible to transition to the next behavioral transformation phase, similar to the target user at that time, and further to the maintenance period, leading to self-management. It suggests.

  The meal restriction determination unit 50 includes a tolerance determination unit 501 that determines the tolerance of meal guidance according to the behavioral change phase of the target user, and the meal restriction for eliminating the difference in the extracted meal contents, The proposal is relaxed to allowance according to the behavior change phase of the target user.

  FIG. 4 is a diagram illustrating the relationship between the behavior change phase of the target user and the tolerance level. If the behavior change phase of the target user is in the period of interest, the rapid meal restriction becomes an excessive burden and the meal restriction is There is a high risk that it will not be possible to continue. Therefore, in the present embodiment, the tolerance for dietary restriction in the period of interest is set to “0.2”, for example, and “8 grams (40 grams × 0.2)” corresponding to the tolerance of the difference amount is set to the current fruit intake. “68 grams” in addition to “60 grams” is suggested as a relaxed limit on fruit intake.

  On the other hand, if the behavior change phase is the preparation period, the tolerance for dietary restriction is set to “0.5”, for example, and the current fruit intake “60 grams” is equivalent to the allowable amount “20 grams (40 grams × 40 grams × 0.5) "plus" 80 grams "is suggested as a relaxed limit on fruit intake.

  In addition, if the behavioral change phase of the target user is the execution period, the tolerance of the guidance policy is set to “0.9”, for example, and the current fruit intake “60 grams” is equivalent to the allowable amount “36 grams (40 grams × 40 grams × 0.9) "plus" 96 grams "is suggested as a relaxed limit on fruit intake.

  Furthermore, if the behavioral change phase of the target user is the maintenance period, the difference of “40 grams” is added to the current fruit intake “60 grams” in order to propose as it is without relaxing the determined dietary restrictions. “100 grams” is suggested as the limit of fruit intake.

  According to the present embodiment, since it is possible to propose a dietary restriction with a track record in light of the contents of the target user at the time of the target user who has succeeded in the meal guidance and led to self-management for the target user who needs the meal guidance, Dietary guidance that is reasonable and compelling is possible.

  Further, according to the present embodiment, in the meal guidance for improving the difference between the target user's meal content and the target user's meal content, the lower the behavior change phase of the target user, the less the meal restriction, The burden is reduced and the continuity of dietary guidance can be improved.

  Furthermore, according to the present embodiment, the user group is clustered based on the meal contents, and the meal restriction is determined in light of the meal contents at the time of the target user who belongs to the same cluster as the target user and succeeded in the meal instruction. This makes it possible to restrict meals according to the target user's eating tendency and preferences, and to provide efficient and highly continuous meal instruction.

[Second Embodiment]
FIG. 5 is a functional block diagram showing the configuration of the second embodiment of the present invention. The same reference numerals as those described above represent the same or equivalent parts, and the description thereof will be omitted.

  In the first embodiment described above, the content of the meal restriction determined by the meal restriction determination unit 50 is described as being presented to the instructor or the target user. However, in this embodiment, the content of the meal restriction determined and the target It is characterized in that a menu suggesting unit 60 is provided that proposes a food menu that satisfies the user's preference and meets the target user's preference based on the user's preference.

  The menu DB 70 stores ingredients necessary for various dishes, nutrients and calories included in each ingredient. In the menu suggestion unit 60, the preference estimation unit 601 estimates the user's preference from the target user's meal log and attribute information. The menu suggestion unit 60 searches the menu DB 70 for a meal menu satisfying the meal restriction content determined by the meal restriction determination unit 50 and the target user's preference, based on the estimation result regarding the target user's preference, and the instructor or the target Present to the user.

  FIG. 6 is a diagram schematically representing the functions of the menu proposing unit 60 and the menu DB 70. In the target nutrient matrix D1, nutrients and their amounts corresponding to the target nutritional balance are registered. In the nutrient × food matrix D2, the relationship between the nutrient and the food containing the nutrient is registered. In the weighting coefficient matrix D3, weighting coefficients for increasing or decreasing the amount of each food material are registered. In the ingredient × dish matrix D4, the relationship between the ingredient and the dish that can be provided using the ingredient is registered. In the dish × menu matrix D5, the relationship between the dish and the menu including the dish is registered.

  In the present embodiment, the nutrients contained in the meal contents taken when the target user is in the same behavior modification phase as the target user and the amount thereof are registered in the target nutrient matrix D1. In the weighting coefficient matrix D3, weighting coefficients for increasing or decreasing the amount of each food material according to the determined meal restriction are registered. Therefore, if the product of each matrix is obtained, it is a menu for bringing the nutrition balance of the target user closer to the nutrition balance of the target user at the time, and in accordance with the preference of the target user and according to the behavior change phase of the target user Menus with less restrictions are output.

  According to the present embodiment, a menu of dishes according to the determined meal restriction can be provided to the instructor or the target user, so that the target user can easily recognize a dish that meets the meal restriction and suits his / her preference. become.

[Third embodiment]
FIG. 7 is a functional block diagram showing the configuration of the third embodiment of the present invention. The same reference numerals as those described above represent the same or equivalent parts, and thus the description thereof is omitted.

  In the second embodiment, it has been described that a dish menu that reflects the meal restriction determined by the meal restriction determination unit 50 is proposed. However, in the present embodiment, a store or a home delivery service that can purchase the food of the menu. It is characterized in that a possible trader is searched based on the current position of the target user and the result can be provided to the target user and the instructor.

  From each target user, position information on the current position measured by each user terminal is periodically transmitted and managed in the position DB 80. The current position of each target user may be estimated based on a user action schedule registered in advance. In the provider DB 90, a restaurant that can sell dishes that conform to the meal guidance policy and its address, or a caterer that can deliver the dish and its delivery area are registered.

  Based on the current location of the target user, the provider introduction unit 100 selects from the provider DB 90 candidates for restaurants or restaurants that can provide the target user with a menu of dishes that reflect the determined meal restrictions. Multiple selections are made, and the store map, ordering method, fee, meal content, etc. are provided to the target user directly or via the instructor.

  According to this embodiment, since the restaurant and the caterer candidate and the access method that can provide meals according to the meal restriction can be presented according to the current position of the target user, the target user can eat according to the contents of the meal restriction. Can be taken easily anytime and anywhere.

  In each of the above-mentioned embodiments, the meal content of the target user is compared with the meal content of the target user at the time of the target user who succeeded in the meal guidance and led to self-management, and proposes a meal restriction that can eliminate the difference However, the present invention is not limited to this, and a difference may be obtained by comparing ideal meal contents calculated from a meal balance guide or a food exchange table.

  Alternatively, the optimal meal content for each target user depends on age, sex, various vital data, and also attributes at the gene level, so calculation and optimization based on attribute information unique to each target user Differences may be obtained using the content of the meals as a comparison target.
