"<< Background >>According to OECD-EU and Turkey data, approximately 15% of the world population consists of individuals with disabilities. According to United Nations Children's Fund reports, there are eighty million children with mild and moderate disabilities under the age of 18. The European Union (EU) Commission stated in the 2021-2030 Disability Rights Strategy that efforts should be made to ensure that disabled people access health services on the basis of equality. However, in some unexpected situations, access to these services may be interrupted. In such a situation, the sustainability of health depends on the healthy lifestyle behaviors (HLBD) of the individual. Unfortunately, the knowledge and behaviors of disabled individuals towards a healthy lifestyle are not at the desired level.COVID-19 has affected the whole world in a short time, starting from China in December 2019. Due to the rapid increase in the number of cases and deaths, the World Health Organization (WHO) has described this crisis that threatens public health as a pandemic on March 11, 2020. One of the most affected by the COVID-19 pandemic is the European continent. WHO draws attention to social isolation by emphasizing the importance of avoiding crowded environments and staying at home in order to protect against the virus. The United Nations has declared that children with disabilities are a vulnerable population and their isolation is mandatory. Considering the effect of the mutant virus on children, it is obvious that more attention should be paid to children with special needs. COVID-19 has the potential to affect all individuals physiologically, spiritually, and socially, whether they get the disease or not. It affects the musculoskeletal and cardiopulmonary system functions as a result of the decrease in the physical activity levels of the individuals, especially due to the duration of staying at home and the time spent in front of the screen in distance education, and psychologically, it causes an increase in the incidence of anxiety, stress, and depression. Due to these physical, mental, and social impacts, it is estimated that the participation of disabled individuals in social life will be seriously affected in the long term and their health expenses will increase. The EU Commission stated that people with disabilities are among the most affected by the COVID-19 crisis and that it is necessary to strive during the crisis to ensure that the quality of life of people with disabilities is improved and their rights are guaranteed (https://ec.europa.eu/cyprus/news/20210303_2_en). Parallel to this, the EU has started to work on combating the pandemic and reducing the effects of the crisis. In March 2021, the EU and UNICEF announced that they are launching a program to reduce the impact of COVID-19 on the most vulnerable children and families. However, this problem has not been addressed specifically for children with special needs.In addition to the students with special needs (SSN), during the distance education given during the pandemic process, teachers also face various physical and mental health problems due to their prolonged immobility in front of the screen while teaching. It is possible to minimize the short and long-term, direct and indirect effects of the pandemic on SSN and their teachers, and therefore to keep social participation and quality of life at the highest level both during and after the pandemic (to the extent permitted by pandemic conditions) with health promotion strategies. For this reason, during this crisis faced by the world, countries to improve health need studies focusing on ""Development and Sustainability of HLB"", especially for SSN and their children.<< Objectives >>Within the scope of the project, it is aimed to improve the HLB knowledge, skills and competence of the SSN and their teachers, and to create a guide and interactive book that enables the development and sustainability of HLB in crisis situations such as COVID-19 for SSN and their teachers. In this project, HLB will be discussed under the heading of physical activity, nutrition and psychological well-being. With the guide that will develop the HLB to be created in order to enable the target population to overcome the COVID-19 pandemic process with the least impact and to reduce the long-term effects of the pandemic;Primary-To increase the physical activity level of the participants by at least 30%- Raising awareness of the participants about healthy eating habits-To improve the psychological well-being of the participants by 50%- To reduce the anxiety level of the participants by 50%-To increase the knowledge level and competence of teachers about HLB by at least 70%- To ensure that the experiences gained in the realization of these goals are shared by the partners-To provide an innovative perspective on the development and maintenance of health in children with special needs in crisis situations.Secondary- With this project, to improve the language skills of the partners in the project, to increase the intercultural interaction- To contribute to the transnational masses by providing awareness of the needs of children with special needs in crisis situations such as pandemics.- To feel the European culture by producing solutions to the problems experienced by the disabled individuals and their close environment on the basis of equal opportunity without considering prejudice, racism and xenophobia<< Implementation >>The learning, teaching, training (LTT) activities will be implemented to the teachers and SSN for their HLB knowledge, skills, and competence. Before all activities, the participants will be assessed via questionnaires (Semistructured Assessment Form, Healthy Lifestyle Behavior Scale-II, International Physical Activity Questionnaire Short Form, Beck Depression Scale, Visual Analogue Scale for anxiety, Healthy Nutrition Attitude Scale) to determine the impact of the activities in this project. The questionnaires will be performed 3 times at the beginning, mid-term, and end of the project. LTTs will include the activities that are consist of adapted motor activities, psychological intervention, evaluation, elaboration of the intervention plan, stress management, and healthy nutrition. Academicians (physiotherapists and sports trainers) will provide knowledge and practice about physical activity to the learners. The SSN will be involved in the training about HLB, the session of physical activities, the handicraft workshop, STEAM workshop, healthy snacks workshops, and the stress management workshop. The handicraft workshops and STEAM workshop will be used to maintain psychological well-being and will be carried out by the teachers in the schools. The physical activities in LTTs will have differed via the exercise selection such as strengthening the upper extremities, strengthening the lower extremities, stretching/relaxing exercises, posture exercises, strengthening the core and back muscles, balance and coordination exercises, and aerobic exercises (brisk walking, jogging, dance therapy for cardiovascular endurance). After each LLT, the partners will make a pilot implementation to practice what they have learned. During the pilot implementation (local activities), the learners will also benefit from innovative methods. Within the scope of this project, local training given for the development and maintenance of HLB will be given online via telecommunication and computer systems. The exercise videos, healthy nutrition videos, and stress management videos will be created by specialists. The accessibility of the videos planned in the project is important in terms of being accessible by everyone with equal opportunities. For this reason, communication will be provided via WhatsApp application and ZOOM due to having it mobile phone in every home, and training/videos will be distributed via mobile phone. In addition, training materials to be used to improve HLB will go beyond brochures and posters and will be provided with an interactive book. Exercises (strengthening, stretching, posture exercises, cardiovascular endurance, balance and coordination, core stabilization) benefits of physical activity, healthy nutrition, stress management, and activities to maintain mental health are the main topics of the interactive book. Additionally, all videos used within the scope of the project will be uploaded to the project web page and the target population will benefit from these outputs asynchronously. It is planned to establish WhatsApp groups by the partners within the scope of local activities. A key-person experienced in physical activity and a key person experienced in nutrition who is a member of the teams of University partner will provide mentorship to these groups. End of the pilot implementations, the consortium partners will give feedback for the good practice. The partnership will create the guide and interactive book according to the feedback from the pilot implementation as well as scientific knowledge.<< Results >>After the LTT activities, the partners will create a guide, an interactive book, and training videos regarding physical activity, exercises, stress management, and healthy nutrition. After ending of the project, the consortium partners expect these results; 1) Formation a guidelines for enhancing and sustaining healthy lifestyle behavior in crisis situations2) Creating an interactive book that enables healthy lifestyle behavior to be adopted and reinforced3) 30% increase in the physical activity level of the participants4) A raise in the awareness of the participants about healthy eating habits5) 50% improve in the psychological well-being of the participants6) 50% decrease in the anxiety level of the participants7) 70% increase in the knowledge level and competence of teachers about HLB8) Sharing of the gained experiences 9) The improvement in the language skills of the partners participating in the project, to increase the intercultural interaction10) A contribution to the transnational masses by providing awareness of the needs of children with special needs in crisis situations such as pandemics.11) The feeling of European culture by all partners in solving the problems of people with disabilities and their immediate surroundings12) Development of awareness of European citizenship13) Promoting of the transnational cooperation"
