There is a large diversity of mobile applications related to diet control and physical activity, mainly directed to adults and without any medical control. CoviHealth project consists of the implementation of a mobile application for young people to promote healthy dietary habits and physical activity based on anthropometric parameters control and gamification. The main contribution of this paper is a detailed specification of an integrated mobile for promoting healthy habits for young people. Additionally, it leverages the effects of the gamification and medical control on stimulating education with healthy habits. Even though other mobile applications have some features that the proposed application has, to the best of our knowledge, a standardized specification for the integration of activity recognition, healthy habits and food intake for teenagers lacks. · Mathematics of computing → Statistical graphics; · Computing methodologies → Neural networks; · Applied computing → Computer-aided design; Health informatics; Bioinformatics.

CoviHealth: Novel approach of a mobile application for nutrition and physical activity management for teenagers. In EAI International Conference on Smart Objects and Technologies for Social Good (GoodTechs ’19), September 25ś27, 2019, Valencia, Spain. ACM, Valencia, Spain, 6 pages. https://doi.org/10.1145/3342428. 3342657 1 INTRODUCTION To date and to the best of our knowledge, the use of the technology by teenagers in secondary schools exploits the existence of new healthcare problems related to the childhood obesity and the sedentary lifestyles [20, 21]. The main objective of CoviHealth project consists in the use of the devices that promote the sedentary and lonely lifestyles to stimulate an increased level of physical and socialization. In order to achieve this goal, the development of a mobile application for Android devices is proposed. The development of this type of mobile applications is related to the Ambient Assisted Living (AAL) subject, assisting and motivating the young people to adopt healthy diet habits and promote physical activity [5, 9, 10, 26]. GoodTechs ’19, September 25–27, 2019, Valencia, Spain The existing mobile applications in the market are mainly related to diet and nutrition, including the measurement of the energy expenditure, the calories intake, the calories needed, and a food database [6, 7, 22ś24, 26]. Currently, the mobile applications related to physical activity and diet control existent in the online application stores are majority prepared to adults. There is a lack of mobile applications explicitly prepared for young people, acknowledging their unique needs, promote their use, including gamification to motivate learning, medical control, among others. The proposed mobile application includes monitoring of lifestyles with an educational component for nutrition and physical activity, medical control, and registration of anthropometric values. These components are expected to motivate teenagers to use this type of mobile applications. The inclusion of a gamification component is expected to motivate young people to use this mobile application. This paragraph finishes the introductory section. A summary of the literature review is presented in section 2. Section 3 presents the study design, the architecture of the system and the statistical methods that will be used for the statistical analysis of the data collected. The results are presented in section 4, including the features of the mobile application and its benefits. In the end, section 5 presents the discussion and conclusions. 2 RELATED WORK Reviewing scientific articles in a domain involves systematic but time consuming steps, and in order to improve the process and find relevant articles more quickly, we utilised the NLP-based toolkit described in [29]. Currently, mobile devices are commonly used for everyday activities, and they can be used for nutrition and physical activity purposes [3, 4, 18, 28]. According to the research performed in Google Play Store [15], which included 250 mobile applications, we analyzed the features of 82 mobile applications, verifying that all mobile application in this research are very similar, and they are mainly based in the monitoring of the diet, weight and Body Mass Index (BMI). Based on the analysis performed, only 24% of the mobile applications (20 of 82) are presented in some scientific studies. The major part of the mobile applications are related to łHealthž (55%), 20% of the mobile applications are related to łDiet and Nutritionž, 15% of the mobile applications are related to łEducationž, and, finally, the remaining 10% of the mobile application included in scientific studies are related to łPhysical activityž. However, the major part of these mobile applications is only referred to in the study or its features are presented with further analysis and validation. Furthermore, the major part of the mobile applications analyzed is related to łDiet and Nutritionž (51%), being the remaining mobile applications categorized as łHealthž (22%), łEducationž (14%) and łPhysical activityž (13%). The next step was to analyze in detail the applications, extracting the features of the mobile applications. The essential features available in the mobile application are presented in Table 1. Additionally, we verified that the significant part of these mobile applications is related to diet control, e.g., calories needed and intake, food database with the indication of calories, diet diary and diet plan, and anthropometric parameters, e.g., weight, height and calculation of the Body Mass Index (BMI). However, other essential features were highlighted in the mobile applications analyzed, including the registration of goals, physical activity level and an educational component. Regarding the mobile application included in łPhysical activityž, the major part of these mobile applications is related to the registration of the physical activity and the calculation of the calories burned. In addition, only 25% of the mobile application included efficacy analyses in research studies. As the effect on health is the most critical for the use of this mobile application, the depth studies found were mainly related to the mobile applications classified as łHealthž, including Lifesum - Diet Plan, Macro Calculator & Food Diary [14], Calorie Counter- MyFitnessPal [11], Samsung Health [16], Calorie Counter ś MyNetDiary [12], and Calorie Counter by FatSecret [13]. Table 1: Summary of the most relevant features on each category. Features Number of mobile applications Diet Diet diary 28 Calories needed calculate 28 Food database with calories 27 Calories Intake 26 Diet plan 22 Macronutrients intake 19 Recipes 19 Anthropometric parameters Weight/Height 52 Age 42 Genre 42 BMI 23 Social Goals 35 Education 25 Physical activity level 25 Reminders 16 Physical activity Calories Burned 26 Exercise diary 19 Training plan 16 Medical parameters Medication diary 2 Diabetic registration 2 Allergies registration 2 Vital parameters Blood pressure 2 Pulse 2 Lifesum - Diet Plan, Macro Calculator & Food Diary was analyzed by the authors of [17], revealing that exists a correlation between the body fat of the individual and the body fat measured by the mobile application. CoviHealth: Mobile application for teenagers In [8], Calorie Counter ś MyFitnessPal was analyzed, concluding that the information provided to the user was very complicated for the everyday use of this mobile application. An early attempt at designing personalized healthcare systems is proposed in [19], where authors describe a novel recommendation algorithm for healthcare based on data collected from a mobile sports application ś SportyPal. Samsung Health was analyzed in [1], comparing the mobile application in two different models of mobile devices and placed in distinct parts of the subject’s body, being that, in all devices, the best results were achieved with the mobile device in the arm, reporting a Root Mean Square Error between 3.6% and 5.4%. In [25], Calorie Counter ś MyNetDiary was analyzed, where it returned satisfactory results and 60% of the participants in the study considered this mobile application is better than others. Finally, the mobile application named as Calorie Counter by FatSecret was analyzed in the study [2], concluding that the measurement of the calories intake by this mobile application does not correspond to the real values, i.e., the measured value of the calories intake is 14% higher than the real value. GoodTechs ’19, September 25–27, 2019, Valencia, Spain where the privileges are the same between the Web Platform and the mobile application. 3 METHODS 3.1 Study design This study consists in the implementation of a mobile application for the Android platform because it is the most used platform in the market [27]. The developed mobile application will be distributed to at least 356 volunteered students from a secondary school aged between 13 and 18 years old, where the population selected will be mainly teenagers. The mobile application will allow the control of the monitoring of the anthropometric parameters, diet plan and training plan by the healthcare professionals. In addition, this study includes some training sessions in the selected school to educate teenagers about nutrition and physical activity. In order to monitor the effects of the use of the mobile application, we will use questionnaires about the current lifestyle during the time of the study regularly for two months. 3.2 System Architecture The system proposed named as CoviHealth is based in a three-tier layer model (see Figure 1), which it is composed by a mobile application for the registration of the different data, and a Web platform mainly used for the management and healthcare providers. According to EU General Data Protection Regulation (GDPR), the connections between the clients (i.e., desktops and mobile devices) and the remote server are performed by connection with Secure Sockets Layer (SSL), in order to reduce the problems with the privacy of the data acquired. The data will always be accessible to the users of the different platforms, where the management, including the deletion of the data, will be allowed. As users with different privileges access this system, the users’ data is available in the Web Platform for all registered doctors, but the data cannot be changed without the consent of the user. The editor will only manage the contents in the Web Platform, and the administrator can manage the permission in the Web Platform. The user can register his/her data in all components of the system, Figure 1: Architecture of the system proposed. 3.3 Hypothesis for Data Analysis The data will be acquired from the individuals that are selected and classified as a Gauss distribution, where the data will be acquired with the questionnaires filled before and after the time of the study. The number of individuals needed to obtain significant results was calculated to the t-Student test. According to the responses provided in the questionnaires, the acceptance of the proposed mobile application will be evaluated to verify the acceptance of the mobile application by young people, promoting healthy lifestyles. 4 RESULTS 4.1 System Proposed Regarding the related work in this subject, the system proposed named as CoviHealth includes two components, these are a Web Platform and a Mobile Application. This system has different types of users with different levels of permissions, including standard user, administrator, doctor and editor, where the user is the unique type of user that has permissions to use the mobile application and the remaining types of users only perform the management in the Web Platform. The mobile application should encourage the improvement of the diet and nutrition of users, including different features to increase the use of the mobile application. These are: • User management ś Registration; ś Login; ś View/Edit user details; • Physical activity management ś Goals registration and validation; GoodTechs ’19, September 25–27, 2019, Valencia, Spain • • • • • • • ś Physical activity monitoring with a pedometer (see Figure 2); ś Goals registration and validation; ś Location monitoring for the challenges; ś Summary of the daily, week and month physical activity; Nutrition ś Diet plan with calendar; ś Training plan with calendar; Questionnaires ś Initial questionnaire related to the physical, diet, nutrition and personal data of the user; ś Monthly questionnaire to evaluate the user; Anthropometric parameters management ś Body fat and muscle mass registered with an image that the user customize an image with his/her body; ś BMI calculation; Home ś Curiosities; ś Tips; Gamification ś Gain points and allows the generation of a QR code in order to get discounts in shops; ś The points are gained: ∗ With the use of the mobile application, e.g., opening the different sections; ∗ Each time that the user opens the mobile application; ∗ With the performance of each quiz; ∗ With the performance of challenges; ś Challenges: ∗ Challenges per week ∗ Group challenges; Medical ś Medication diary; ś Biometric parameters registration; Social ś Integration with social networks; ś Reminders.

As the primary goal of the proposed mobile application is to motivate the teenagers to use the mobile application and to be educated about nutrition and physical activity, the highlighted features will captivate the teenagers to use the mobile application with curiosities, tips, medical control and gamification. The gamification is the main feature that may motivate the use of the mobile application, where the user gains points that can be converted as discounts in different shops. The integration with social networks to share the values of the physical activity, diet and nutrition are very common in modern mobile applications and it will contribute to the motivation of the users. The medical control is another most central feature because it provides reliable information to teenagers with a personal captivation of the users. Even though recognizing the physical activity with teenagers on the field is a challenging task [31], some machine learning approaches, such as [30], could be utilized to better recognize and the exact physical activity, even on mobile devices. 4.3 Expected results The mobile application proposed in this study will be evaluated to verify the satisfaction of the users with the mobile application as GoodTechs ’19, September 25–27, 2019, Valencia, Spain well as its utility. It is expected that the inclusion of the gamification increases the use of the mobile application because the main population will be teenagers. It is also expected that the inclusion of medical control increases the acceptance and reliability of the mobile application. The trustworthy and personalized health monitoring of the mobile application allows teenagers to obtain better results with the implementation of healthy habits. In conclusion, this mobile application will present dynamic content, i.e., tips, curiosities and challenges, to motivate the use of it, increasing the acceptance of the mobile application by the teenagers. In the end, it may motivate performing physical activities. 5 DISCUSSION AND CONCLUSIONS Healthy living habits are essential for improving the quality of life in order to reduce the rate of future pathologies related to poor eating habits and sedentary lifestyle. CoviHealth is a multidisciplinary project that includes the development of a mobile application for nutrition and physical activity in order to evaluate and improve the habits of young people. This project will be developed in cooperation between professionals from computer science engineering and medicine from the Universidade da Beira Interior, Covilhã, Portugal. The main functionalities of the proposed mobile application will be the monitoring of physical activity, reminders, possibility to define the training plan, medication diary, medical control, where the innovation of this mobile application is focused on the inclusion of medical control, tips, curiosities and gamification. In the future, the proposed mobile application will be implemented and a group of young people from a secondary school will be selected for the tests in order to verify if the innovation proposed stimulates the interest in the mobile applications related to nutrition and physical activity. 6 ACKNOWLEDGMENTS This work is funded by FCT/MEC through national funds and when applicable co-funded by FEDER ś PT2020 partnership agreement under the project UID/EEA/50008/2019 (Este trabalho é financiado pela FCT/MEC através de fundos nacionais e quando aplicável cofinanciado pelo FEDER, no âmbito do Acordo de Parceria PT2020 no âmbito do projeto UID/EEA/50008/2019).
