Description

  The present invention relates to a meal guidance support apparatus that performs appropriate meal guidance for a subject who needs meal guidance by a specialist such as a registered dietitian, and in particular, optimizes the content of the meal guidance according to the behavior change phase of the subject. The present invention relates to a meal guidance support device.

  Lifestyle-related diseases such as metabolic syndrome and diabetes are mainly caused by lifestyle and obesity, and the first choice of treatment is diet therapy. In the standard diet therapy, it is common for subjects to continue self-management under dietary guidance from doctors and dietitians.

  In such self-management in dietary guidance, providing a specific method for improving lifestyle habits is an important factor as one method for promoting behavioral change. Here, behavioral change means changing a habitual behavior pattern.

  Patent Document 1 discloses a lifestyle improvement support method using a test result and a questionnaire. Patent Document 2 discloses a technique having a configuration that calculates or acquires a user's calorie intake and warns in the case of excessive intake. Patent Document 3 discloses a method of giving advice in consideration of both ingested calories and consumed calories.

  Non-Patent Documents 1, 2, and 3 show systems in which a user uploads meal images to a server, and a registered dietitian provides guidance. Such a system has an advantage that the user can easily receive dietary guidance from a registered dietitian. In such a system, in general, in order to reduce the labor burden of a registered dietitian, a meal photo is compiled for about 3 days and comments and guidance are given. Also, as in Non-Patent Document 3, there is a case where a completely self-managed system is used.

  Systems that involve self-management are often predicated on highly motivated people, and it is sufficient to give food evaluations or provide self-management tools, but for those who are not motivated in the first place, Such a system tends to be insufficiently taught.

  Accordingly, the inventors of the present invention invented a system that realizes communication with a dietitian at the same time as evaluation of meal images in order to enhance and maintain motivation for the health management of the subject, and applied for a patent (Patent Document 4). ).

  In general, communication is required to increase motivation. 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, it is necessary to raise the self-efficacy of “they can do it for me” by fostering relationships of trust and counseling, etc. for patients in interested and preparatory periods. In other words, not only regular input of knowledge, but also how to communicate, build trust and change awareness. For this reason, it is relatively easy to support patients in the execution period, but there is a problem that it is extremely difficult to support patients in the interest period and the preparation period.

  On the other hand, when only simple meal guidance is performed, it is required to refer to information provided to a patient with a meal image at the center. That is, an expert first looks at a meal image and examines the content, and refers to the accompanying interaction with the patient. Therefore, as a system for assisting such a reference, for example, a UI that can list meal images on a calendar or the like as shown in FIG. 9 is suitable.

  However, in order to improve and maintain motivation, there are situations in which it is desired to refer to the contents of a meal from the contents of communication in addition to the above reference. For example, if a user who has not responded to the comments of a dietitian has responded that “it is getting better”, specify what the response is for and specifically The persuasive power of the respondent increases. Rather than answering, “It's because the meal content has improved,” it has made great progress in the “... Monday… Sunday meal ...” meal. The person who answered "I think" can clearly show the rationale, and the user's persuasive feeling increases and the self-efficacy increases.

  In addition, it is possible to know where exactly was good, leading to improvement in behavior. In other words, in a system for users at this time, "reference with a focus on meal photos" and "reference with a focus on communication" must be realized simultaneously. However, the conventional UI has a problem that only one function is realized.

  Furthermore, when prompting the patient to change his / her behavior, communication such as encouragement is required along with providing information. Here, it is known that the optimal ratio between guidance by information provision and guidance by communication varies depending on the behavioral transformation phase. However, in the conventional technology, the instructor estimates the patient's health ability and matches the health ability. There is a problem that it is difficult for the instructor who is not used to teaching.

  An object of the present invention is to provide a meal guidance support apparatus that solves the problems of the prior art, estimates health ability by a model based on a behavior change model, and optimizes the content of meal guidance according to the ability. is there.

  In order to achieve the above object, the present invention provides an information processing apparatus for providing information to a target person of meal instruction and assisting instruction by communication based on information exchanged between the target person and the instructor. To estimate the behavior change phase of the child, a knowledge DB for accumulating knowledge used for information provision guidance, a means for calculating the total amount of guidance by the instructor to the target person, and information provision guidance based on the estimation result of the behavior modification phase Means for determining the amount of communication, means for determining the amount of communication instruction based on the estimation result of the behavior change phase, means for determining the quality of information providing instruction based on the total instruction amount,

  Means for extracting the corresponding knowledge from the knowledge DB based on the determination result of the quantity and quality of the information providing instruction, and means for presenting the amount of the communication instruction and the extracted knowledge to the instructor. Features.

  According to the present invention, it is possible to optimize the guidance weight, quantity and quality of information provision guidance and communication guidance according to the behavior change phase of the guidance target person and the past training history. Dietary guidance is possible.

It is the figure which showed the structure of the meal guidance assistance system of this invention. It is the figure which showed the correspondence of instruction | indication weight and action change phase. It is a board figure which shows the example of a will ability growth curve and a literacy ability growth curve. It is a functional block diagram of the meal instruction assistance device concerning one embodiment of the present invention.

It is the figure which showed the structure of knowledge DB. It is the figure which generalized the structure of the user interface. It is the figure which showed the example of a display of an information provision timeline and a communication timeline.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of a dietary guidance support system to which the present invention is applied. A dietary guidance target person (for example, a diabetic or hypertensive patient) and a supervisor (for example, a registered dietitian) Meal information is shared via the support device 1 and the user terminal 2, and further information provision and communication are performed, whereby meal guidance by the instructor proceeds.

  The meal guidance support apparatus 1 dynamically determines the stage of behavior change (behavior change phase) of the target person from the meal information provided from the target person, the amount and result of the guidance, and enters the current action change phase of the target person. Support appropriate dietary guidance.

  In the present invention, the method of teaching the subject is classified into (1) information provision by a registered dietitian and (2) communication between a registered dietitian and the subject, and based on the analysis results for each phase of the behavioral change. And defined the best teaching weights for each behavioral transformation phase.

  The instruction weight is an index indicating how much weight is given to “information provision” and “communication” for the meal instruction for the target person. As shown in FIG. The weight of provision guidance is increased, the weight of communication guidance is increased as the period of interest progresses from the preparation period, and the weight of communication guidance is the highest in the execution period. After that, the weight of information provision guidance is increased again as the maintenance period progresses.

  And in this invention, the element which determines the ability (health ability) for the subject to improve his / her health condition and to achieve his / her health goal by regulating his / her diet so that he / she can maintain his / her improved health condition However, it is assumed that this is the sum of (1) “will ability” that is expected to increase due to communication guidance, and (2) “literacy ability” that is expected to increase due to information provision guidance.

  In this embodiment, the communication between the registered dietitian and the target person is assumed to be “encouragement” or “giving up” from the registered dietitian to the target person, rather than general two-way information transmission. . Therefore, “communication guidance” in the present embodiment is intended to enhance the self-efficacy of the subject by the nutritionist encouraging or complimenting the subject.

  FIG. 3 is a diagram showing an example in which the health ability is increased by a subject in an indifference period receiving information provision guidance and communication guidance according to the guidance weight shown in FIG.

  The relationship between the behavior change phase when focusing on will ability and health ability (will ability growth curve A) is a cumulative graph of the amount of communication in FIG. 2, and the behavior change phase and health ability when focusing on literacy ability 2 (literacy ability growth curve B) is a cumulative graph of the information provision amount in FIG. 2, and the health ability is proportional to the total sum of each instruction amount (straight line C).

  Here, paying attention to the intention ability curve A, the health ability is almost “0” in the first indifference period, and when the maintenance period comes, the behavioral change is completed and becomes “1”. In the present invention, if it is assumed that the transition period from the indifference period to the maintenance period is the target of support, and the behavioral change is caused by the accumulation of the change in the behavior and vital value of the subject, the period from the interest period to the execution period Since the subject is a subject such as “I am willing to do it, but I cannot take a step,” more encouragement (communication) is required.

  On the other hand, communication in the indifference period seems to be a pressing part, and since the willingness is sufficiently developed after the execution period and self-management methodologies are established, much communication is necessary. Absent.

  It is necessary for the interested people to have self-efficacy by appropriately evaluating their efforts and encouragement or compliment. In other words, while the evaluation is focused on the “behavior” in the period of interest, the evaluation focusing on the “result” becomes closer to the execution period. In other words, even a “slight change” is overestimated when the phase does not progress, and it is not evaluated that it is not a “relatively large change” when the phase is advanced. This means that an appropriate evaluation is based on the degree of dissociation (%) from one's own ability (when the level is low, it is necessary to evaluate how hard you have worked for that level).

  In this embodiment, guidance is composed of (1) communication (encouragement), (2) information provision, etc., but considering communication, there is only a slight amount at the stage where the phase does not progress (interesting period, preparation period, etc.). Even if there is a serious change, it shall be detected and communicated. The content should detect many positive changes and give up more. On the other hand, at the stage where the phase has advanced, communication is required to pay attention to negative changes.

  Considering information provision, it is not necessary to provide much information when the phase does not progress. On the other hand, as the phase progresses, willpower is created, so it is necessary to provide a lot of information that can use that willpower. The content requires more general knowledge at the stage where the phase does not progress (because it needs to be interested), but at the stage where the phase has advanced, more practical expertise is required. I need it.

  On the other hand, when detecting a negative change, the sigmoid curve is reduced. In this case, since a negative change detects only a relatively large change at a stage where the phase does not progress, more general information is given, and individual information is often given when the phase progresses. Of course, even if the behavior change phase has advanced, if it is a very large change, it is desirable to respond individually.

  That is, the threshold for guidance changes according to the behavior change phase. Here, in the present invention, “communication guidance” for changing the intention ability of the target person is considered as a threshold for the amount of change for giving up or paying attention to the action of the target person.

  On the other hand, when detecting a change in literacy, the threshold value is changed in accordance with the change in ability. Here, in the present invention, the above-mentioned “information provision for changing literacy” is considered as a threshold for the width and depth of information to the subject.

  In other words, in the indifference period, it is desirable to provide a wide range of information at a shallow depth so as to match the interest of the target person (so that it does not know what is of interest, so that it can be caught in the network), whereas the phase is advanced At this stage, it is necessary to provide specific information at a deeper depth so that self-management can be performed. At this time, it is desirable to change the “specific information” finally converged according to the instruction purpose of the subject. For example, in the case of diabetes guidance, the knowledge about self-management of diabetes is converged.

  FIG. 4 is a block diagram showing the configuration of the main part of the meal guidance support apparatus 1 according to one embodiment of the present invention, and here, the configuration unnecessary for the description of the present invention is omitted. Such a meal guidance support device 1 can be configured by mounting an application (program) for realizing each function described later on a general-purpose computer or server. Alternatively, a part of the application may be configured as a dedicated machine or a single-function machine in which hardware or ROM is implemented.

  The meal guidance control unit 10 manages meal images and information on meal contents transmitted from a person (patient) of meal guidance, evaluation by each registered dietitian for received meal images, and comments between each subject person and a registered dietitian UI control unit 10a for managing communication and information provision by sending and receiving to realize meal guidance, further visualizing each information and synchronously displaying it in a time-sequentially scrollable manner on the display of each subject person and each registered dietitian Prepare.

  The guidance history DB 20 includes history information 20a of meal contents received from each subject, history information 20b of communication guidance by a registered dietitian to each subject, and history information 20c of guidance providing information from a registered dietitian to each subject. In addition, each identifier (user ID) of each subject is stored in time series.

  The meal information history 20a includes meal images taken by each subject, meal contents and meal times, meal balance guides calculated by a registered dietitian for each meal, evaluation values of food exchange tables, and the like. .

  The communication history 20b includes, for example, comments for evaluating dietary content and comments for encouraging the subject as a response from each subject to the dietary guidance provided by each dietitian for each subject.

  The information provision history 20c includes various types of information provided from the registered dietitian to the subject, the provision date and time, and the like.

  The peculiar event detection unit 30 extracts and quantifies an event (specific event) that is specifically observed in the process of changing the behavior of the subject from the meal information history 20a and the communication history 20b accumulated in the instruction history DB 20. In addition, a change point of a relatively large event that can be recognized as a behavioral change in the subject is detected. In the present embodiment, the following six events are set as extraction targets and change point detection targets as specific events.

(1) Peculiar event A: Evaluation of dietitians for meal images
(2) Peculiar event B: Vital value such as blood glucose level of the subject
(3) Peculiar event C: Meal menu
(4) Singular event D: Meal frequency
(5) Singular event E: Meal timing
(6) Singular event F: Comment from the subject

  Specific events A are five types of quantitative values in the meal balance guide and six types of quantitative values in the food exchange table, and changes in the numerical values are extracted. At this time, a threshold value for the amount of change may be provided and extraction may be performed when there is a certain change. As a change function of the threshold value, it may be changed linearly or may be expressed as a percentage of health ability. If the health ability depends on the cumulative value of communication with the registered dietitian, the health ability may be expressed by a sigmoid function.

Also, the same purpose can be achieved even if the comparison period is extended. When the phase does not advance, the comparison with the previous day may be performed, while at the stage where the phase has advanced, the comparison may be performed every other week. This period interval may be determined with the same threshold as described above.
Furthermore, the magnitude of daily changes can be estimated based on the rate of change from the previous day or the day before. Generally, when the change is small, the phase has not progressed so much, and when the change is large, the phase has progressed considerably.

  The singular event B may be regarded as a sigmoid function similar to the above.

  For singular event C, first look at word changes related to meals. For example, a person who always eats “confectionery bread” at noon can obtain many characters such as “melon bread” and “jam bread”. When this person undergoes behavioral changes and becomes “Ampan” or “Boiled Rice”, which is considered to be relatively good for the body, these conceptual distances are referred to. The degree of change can be quantified by calculating the distance on a concept dictionary (thesaurus) prepared in advance.

  In this case, Ampang has a relatively short distance but Onigiri has a long distance. In addition, when data is obtained to some extent, frequency information may be used. That is, a document vector is generated from a word related to the menu, and the distance between the latest vector and the previous vector may be calculated.

  Regarding singular event D, the more frequent the event, the higher the interest. On the other hand, if the phase exceeds a certain level, it is often necessary to reduce the number of meals.

  For the specific event E, as the meal timing, the regularity of how long the meal is acquired may be used as an evaluation value, and how much it does not deviate from the standard.

  For the unique event F, words related to meals may be extracted from the comment content and classified into vectors. The simplest is a two-dimensional vector of positive and negative words.

  In the specific event analysis unit 40, the specific event variable calculation unit 40a predetermines at least one of the quantitative values a, b, c, d, e, and f of the specific events A, B, C, D, E, and F. By applying to the function f, the singular event variable ΔP = f (a, b, c, d, e, f) serving as the transition index of the behavior modification phase is calculated. When each of the quantitative values a, b, c, d, e, f or the singular event variable ΔP exceeds a predetermined threshold value Pref, the change point detection unit 40b sets this as a significant change point that triggers behavioral change. To detect.

  When the threshold value Pref is set for each of the specific events A, B, C, D, E, and F, for example, the threshold value Pref_a is set for the specific event A, the threshold value Pref_b is set for the specific event B, If the threshold value Pref_c is set for the singular event C, a change point may be detected when a> Pref_a, b> Pref_b, or c> Pref_c.

  The threshold update unit 40c dynamically updates the threshold Pref for detecting the change point according to the current behavior change phase of the target person estimated by the behavior change estimation unit 50 described later, that is, the accumulated value of the specific event. To do. In this embodiment, positive singular event variables that advance the behavioral transformation phase, i.e., the excessive number of meals, the vital value approaches the normal range, the nutritionist's evaluation and the subject's comments are positive. The threshold value Pref applied to the singular event variable in the event of a failure increases as the behavior modification phase progresses.

  On the other hand, negative singular event variables that reverse the behavioral transformation phase, that is, the number of excessive meals further increased, vital values moved away from the normal range, dietitian evaluation and subject comments were negative. The threshold value Pref that is applied to the singular event variable in the event of a failure becomes smaller as the behavior modification phase proceeds.

  Such dynamic thresholding applies a threshold proportional to the sigmoid function for positive singular event variables that advance the behavioral transformation phase, while negative singular event variables that reverse the behavioral transformation phase. Can be realized by applying a threshold inversely proportional to the sigmoid function.

  The correspondence relationship storage unit 80 includes a first correspondence relationship 80a (FIG. 5) between the cumulative value of singular events and the behavior change phase, a second correspondence relationship 80b (FIG. 2) between the instruction weight and the behavior change phase, and a will. The relationship between the ability growth curve A and the literacy ability growth curve B 80c (FIG. 3) is registered in advance.

  FIG. 5 is a diagram showing an example of the first correspondence relationship 80a, in which the correspondence relationship between the behavior change phase (horizontal axis) and the accumulated value (vertical axis) of unique events is stored. FIG. 2 is a diagram showing an example of the second correspondence relationship 80b, in which correspondence relationships between instruction weights (horizontal axis) and behavior change phases (vertical axis) are stored.

  Returning to FIG. 4, as shown in FIG. 6, the behavioral change estimation unit 50 adds the current singular event variable ΔP to the current behavioral transformation phase, that is, the singular event cumulative value ΣP that is the criterion for the behavioral transformation phase. In addition, by updating and applying the updated unique event cumulative value ΣP + ΔP to the correspondence relationship 80a, the current behavior change phase corresponding to the updated specific event cumulative value is estimated. Note that the first behavior modification phase of each subject is manually set in advance by, for example, an individual dietitian conducting an individual interview or the like.

  The total guidance amount calculation unit 90 calculates the total amount of guidance that the registered dietitian has given to the subject, that is, the sum of the total amount of communication guidance and the total amount of information provision guidance as the total guidance amount. In the present embodiment, the total amount of instruction can be represented by the total number of instructions from the registered dietitian to the subject and the total number of words included in the instruction comment.

  The guidance policy determination unit 60 determines a future guidance policy for the subject based on the updated behavior change phase and the total guidance amount.

  As shown in FIG. 7, knowledge DB 100 stores knowledge to be provided with information in order to improve the literacy ability of each instructor. Since such knowledge is diverse, a large amount of knowledge is hierarchically managed according to the degree of specialization in the knowledge DB 100, and each knowledge is subdivided into a plurality of groups for each topic.

  In the fourth layer of the hierarchical structure, general knowledge related to specialized knowledge such as knowledge about meals is accumulated. In the third hierarchy, specialized knowledge such as knowledge of diet for diabetes is accumulated. In the second hierarchy, more specialized knowledge such as knowledge of diabetes is accumulated. In the first hierarchy, the most specialized knowledge such as knowledge of diabetes self-management is accumulated.

  In the guidance policy determination unit 60, the information provision guidance quality determination unit 60 a determines the quality of the information provision guidance based on the calculation result of the total guidance amount by the total guidance amount calculation unit 90. In the present embodiment, the higher the total amount of instruction, the higher the layer of knowledge to be provided to the person to be instructed is.

  The information provision guidance amount determination unit 60 b determines the amount of information provision guidance based on the estimation result of the behavior modification phase by the behavior modification estimation unit 50. In the present embodiment, in the determined hierarchy, the number of topics of the knowledge to be provided to the instructing subject is determined, and as the behavior modification phase proceeds, knowledge on more topics is provided.

  In addition, when selecting the number of topics according to the estimation result of the behavior modification phase from a plurality of topics for each hierarchy, the presence ratio of the appearance words for each topic is analyzed in advance and each instruction for each appearance word is analyzed. Investigate the target's interest index in advance, set priority based on the sum of products of each occurrence word and its interest index for each topic, and select from topics with higher priority Is desirable.

  Alternatively, for each topic in the nth layer other than the lowest layer (fourth layer), the relationship with each topic in the lower (n + 1) layer and the number of presentations of each topic in the lower layer are investigated in advance. Alternatively, a priority may be set for each topic in the nth layer based on the sum of products of the relevance and the number of presentations, and a topic with a higher priority may be selected.

  The communication instruction amount determination unit 60c determines the amount of communication instruction based on the behavior change phase estimation result by the behavior change estimation unit 50. The ratio between the amount of the communication instruction and the amount of the information provision instruction is determined based on the correspondence relationship between the instruction weight and the behavior change phase described with reference to FIG.

  The guidance policy determination unit 60 extracts corresponding knowledge from the knowledge DB 100 based on the determination result of the quantity and quality of the information provision guidance. The guidance policy determination unit 60 further includes a plurality of significant change points detected by the change point detection unit 40b based on the determination result of the amount of communication instruction, which are improvement factors of the behavior change phase. A change point with a larger amount of change is preferentially selected as a number corresponding to the amount of the communication instruction and is messaged.

  For example, if a 20 mmHg decrease in blood pressure value detected on October 0 is selected as a change point, an encouragement message “The blood pressure value has improved by 20 mmHg on October 0” is generated. The knowledge and change points selected as described above are presented to the registered dietitian via the UI control unit 70.

  FIG. 8 is a diagram showing an example of presentation to a registered dietitian. Information providing timeline TL1 for displaying information providing information on a display in a time series scrollable manner and information for communication scrolling in time series The communication timeline TL2 to be displayed is displayed in parallel, and each timeline TL1, TL2 is displayed and controlled so that if one is scrolled, the other is also scrolled in synchronization with this.

  Knowledge extracted from the knowledge DB 100 is displayed in the information provision timeline TL1. In the communication timeline TL2, a number of encouragement comments corresponding to the determined amount of communication instruction are displayed.

  FIG. 9 is a diagram showing a display example of the timelines TL1 and TL2 displayed synchronously. FIG. 9A shows a display example when it is determined that the amount of information provided is reduced and the amount of communication is increased. The communication timeline TL2 displays a number of comments that evaluate the subject's hard work.

  Figure (b) is a display example when both the amount of information provided and the amount of communication are determined to be moderate.Figure (c) is determined to increase the amount of information provided and reduce the amount of communication. It is a display example in the case of. In (b) and (c) of the figure, the amount determined for the communication instruction was “2”, so the communication timeline TL2 indicated that “blood glucose level improved 5/15”, “2/17” Two guidance messages are displayed saying “The number of meals has been reduced.”

  According to the present embodiment, the guidance weight of information provision guidance and communication guidance, the quantity and quality of guidance can be optimized according to the behavior change phase of the guidance target person and the past training history. Optimal dietary guidance is possible.
