Developing a web-based digital platform to encourage activity, healthy eating and hydration to promote healthy ageing in people over 70-years

有强有力的证据表明，力量和平衡练习可以减少跌倒，作为一种单独的干预措施，力量和平衡练习可能是在人群水平上预防跌倒的最具成本效益的方法。运动游戏已经证明了一些成功，这是一种将游戏和体育锻炼相结合的远程康复方法。使用运动游戏系统进行锻炼的优势是，它们可以身临其境、娱乐和享受，潜在地提高了介入计划的依从性、频率和持续时间。关于利用游戏化来促进其他健康行为的证据很少。老年人营养状况不佳往往会导致功能减退、体重减轻、营养不良，并对独立性造成不利影响。拟议的项目计划利用游戏促进锻炼的成功，并计划以类似的形式纳入健康饮食和补水，以促进更健康的行为，不仅是力量和平衡练习，而且是适合老年人的食物和补水。目的：开发一个使用游戏化和数字技术的平台，以促进70岁以上老年人的运动和健康饮食。制定干预措施：通过与主要利益攸关方和最终用户建立伙伴关系，制定干预措施将以用户为中心。初步想法和故事板将与主要利益攸关方讨论，我们将鼓励就游戏背后的关键信息和为获得最佳证据而需要涵盖的关键主题进行公开辩论。这份最初的咨询材料将被用来为原型制作故事板。这个故事板将在3-4个焦点小组中进行讨论，每个小组将举行8-10人，他们要么是关键的利益相关者，要么是潜在的最终用户。根据从重点小组获得的信息，原型将以基于网络的应用程序的形式设计和制作(可使用平板电脑、移动设备或计算机访问)。然后，最终用户将对网上申请进行初步评估，并要求他们对使用混合方法获得的信息的新技术、可用性、可接受性和实用性进行正式评估。在这次评估之后，将有机会修改内容，并根据需要改变用户体验。这将为未来(博士后)随机对照有效性研究提供方法。

There is strong evidence that strength and balance exercises reduce falls and that strength and balance exercise as a stand-alone intervention may be the most cost-effective approach to falls prevention at a population level. There has been some success demonstrated with Exergaming, a type of telerehabilitation that combines gameplay with physical exercise. The advantages of using exergaming systems to deliver exercise are that they can be immersive, entertaining and enjoyable, potentially improving adherence, frequency and duration of an interventional programme. There is paucity of evidence in relation to using gamification to promote other healthy behaviours. Poor nutritional status in older people often leads to decreased functionality, weight loss, malnutrition and detrimentally effects independence. The proposed project plans to build upon the success of exergaming to promote exercise and plans to incorporate healthy eating and hydration in a similar format to promote healthier behaviours not only on strength and balance exercises but also on food and hydration suitable for older populations. Aim: To develop a platform using gamification and digital technology to promote activity and healthy eating and drinking in people over 70-years. Developing the intervention: The development of the intervention will be user-centred by working in partnership with key stakeholders and end-users. Initial ideas and a story board will be discussed with key stakeholders and we will encourage an open debate of the key messages behind the games and key themes that need to be covered for best evidence. This initial consultation material will be used to format a story board for the prototype. This story board will then be discussed in 3-4 focus groups with will be held with 8-10 people in each who will be either key stakeholders or potential end-users. From the information gained from the focus groups the prototype will be designed and produced in the form of a web-based application (accessible using tablet, mobile or computer). The online application will then undergo preliminary evaluation by end-users who will be asked to undertake a formal assessment of the new technology, usability, acceptability and practicality of information gained using mixed methods. After this evaluation there will be an opportunity to modify the content and also change user experience as required. This will inform the methods for a future (post-doc) randomised controlled effectiveness study.
