Abstract

Past studies conducted in urban areas analyzed the impact of the presence of green spaces on public health, and highlighted in particular the psychological benefits of interacting with nature. To investigate a supposed relationship between overweight and dense built environment, we focused on the State of Geneva, Switzerland, and calculated the correlation between Body Mass Index (BMI) in a representative sample of 6663 adults and the percentage of natural areas at the locations where these individuals were living. To this end, we used population-based health data from the “Bus Santé” study (Geneva University Hospitals) and multi-scale land cover maps obtained by means of satellite images and LiDAR data classification. We found little correlation between BMI (as a proxy for health) and land cover data and were not able to verify the working hypothesis at local and regional scales. However, an important phenomenon highlighted here is the difference in the results obtained between the city center and the whole State.

日内瓦地区土地覆盖类型与身体质量指数的关系

过去在城市地区进行的研究分析了绿色空间对公共健康的影响，并特别强调了与自然互动的心理益处。为了研究超重与密集建筑环境之间的关系，我们以瑞士日内瓦为研究对象，计算了6663名成年人的代表性样本的体重指数(BMI)与这些人居住地点的自然面积百分比之间的相关性。为此，我们使用了来自日内瓦大学医院“Bus sant”研究的基于人群的健康数据，以及通过卫星图像和激光雷达数据分类获得的多尺度土地覆盖图。我们发现BMI(作为健康的代表)和土地覆盖数据之间几乎没有相关性，并且无法在局部和区域尺度上验证工作假设。然而，这里强调的一个重要现象是，在城市中心和整个州之间取得的结果存在差异。
