Centre for Diet and Activity Research (CEDAR)

糖尿病、心脏病、癌症和精神健康问题等非传染性疾病占全球死亡人数的60%。不良的饮食和缺乏体育活动在增加患这些疾病的机会方面起着重要作用。据估计，仅缺乏身体活动就造成全球约十分之一的死亡，与吸烟的影响相当。如果饮食符合营养指南，仅在英国每年就可以避免7万例过早死亡。面对这些统计数据，每个人都应该努力做出健康饮食和积极生活方式的个人选择，这似乎是直觉。然而，我们不会孤立地做出这样的选择，我们的饮食和活动水平受到我们生活的更广泛的社会，文化，经济和物理环境以及我们的个人态度和信仰的影响。CEDAR旨在提高我们对影响这些饮食和活动行为的人口水平因素的认识。加深对这些决定因素的了解是制定干预措施以帮助人们采取可持续健康行为的重要一步。CEDAR还旨在评估这些干预措施对短期行为改变和长期健康结果的影响。然而，并非所有影响饮食和体育活动的干预措施都是以改变这些行为为主要目的。事实上，我们的身体活动行为受到我们周围建筑环境结构的强烈影响。因此，CEDAR还对干预措施进行评估，例如交通基础设施的变化，这些措施可能会影响通勤者和休闲体育活动水平，作为副产品，而不是其主要目标。我们收集的证据将帮助政治家，卫生专业人员和整个社会更好地决定如何改善整个人口的健康，无论是通过直接的公共卫生干预措施，还是影响我们生活，旅行和工作的更广泛的方式。

Non-communicable diseases such as diabetes, heart disease, cancer and mental health problems account for 60% of deaths globally. Poor diet and lack of physical activity play an important role in increasing the chance of developing these diseases. Physical inactivity alone is estimated to account for around 1 in 10 deaths worldwide, comparable to the impact of smoking. Seventy thousand premature deaths in the UK alone could be avoided each year if diets matched nutritional guidelines.In the face of these statistics it would seem intuitive that everyone should strive to make individual choices to eat a healthy diet and adopt an active lifestyle. However, we don't make such choices in isolation and our diets and activity levels are driven as much by the broader social, cultural, economic and physical environment in which we live by as our personal attitudes and beliefs. CEDAR aims to improve our knowledge of the population-level factors that influence these diet and activity behaviours. Generating a greater understanding about these determinants is an important step in developing interventions to help populations adopt sustainable healthy behaviours. CEDAR also aims to evaluate the impact of such interventions both on short term behaviour change and, in the longer term, on health outcomes. However, not all interventions that impact on diet and physical activity are designed with changing these behaviours as their primary purpose. Indeed our physical activity behaviour is strongly influenced by the structure of the built environment around us. Therefore CEDAR also undertakes evaluations of interventions such as changes to the transport infrastructure that may impact on commuter and leisure physical activity levels as a by-product rather than their primary objective. The evidence we gather will help politicians, health professionals and society at large make better decisions about how to improve health for the whole population, whether it is through direct public health interventions, or wider ways that influence how we live, travel and work.
