背景：对于许多人来说，体育活动已经被设计出日常生活，导致高水平的久坐和肥胖。多方面的身体活动干预措施，结合个人，社区和环境的方法，有最大的潜力，以改善公众健康，但很少有被评估。研究方法：通过北方爱尔兰的城市复兴项目康斯沃特社区绿道，大约10万人可能会受益于改善的体育活动机会。使用宏观模拟PREVENT模型，我们估计其潜在的健康影响和成本效益。为此，我们模拟了其对心血管疾病负担的潜在影响，即缺血性心脏病，2型糖尿病和中风，以及结肠癌和乳腺癌，到2050年，如果可行的话，增加体力活动。结果如下：如果10%的人被归类为“不活跃”（每周进行不到150分钟的中度活动）成为“活跃”，886例事件（1.2%）和75例死亡（0.9%）可以预防，增量成本效益比为4469磅/残疾调整生命年。对于低至2%的有效性估计，干预仍具有成本效益（18磅411/残疾调整生命年）。平均预期寿命和残疾调整后的预期寿命可以实现小幅增长，绿道人口将受益于减少46年的残疾生活。结论：绿道干预在提高体力活动水平方面具有成本效益。虽然对任何个人来说，直接的健康收益预计都很小，但对整个人口来说，它们是巨大的。除此之外，绿道可能还有健康以外的更广泛的好处。
Background: For many, physical activity has been engineered out of daily life, leading to high levels of sedentariness and obesity. Multi-faceted physical activity interventions, combining individual, community and environmental approaches, have the greatest potential to improve public health, but few have been evaluated. Methods: Approximately 100 000 people may benefit from improved opportunities for physical activity through an urban regeneration project in Northern Ireland, the Connswater Community Greenway. Using the macro-simulation PREVENT model, we estimated its potential health impacts and cost-effectiveness. To do so, we modelled its potential impact on the burden from cardiovascular disease, namely, ischaemic heart disease, type 2 diabetes mellitus and stroke, and colon and breast cancer, by the year 2050, if feasible increases in physical activity were to be achieved. Results: If 10% of those classified as 'inactive' (perform less than 150 minutes of moderate activity/week) became 'active', 886 incident cases (1.2%) and 75 deaths (0.9%) could be prevented with an incremental cost-effectiveness ratio of 4469 pound/disability-adjusted life year. For effectiveness estimates as low as 2%, the intervention would remain cost-effective (18 pound 411/disability-adjusted life year). Small gains in average life expectancy and disability-adjusted life expectancy could be achieved, and the Greenway population would benefit from 46 less years lived with disability. Conclusion: The Greenway intervention could be cost-effective at improving physical activity levels. Although the direct health gains are predicted to be small for any individual, summed over an entire population, they are substantial. In addition, the Greenway is likely to have much wider benefits beyond health.
