Recent studies have examined how the environment can influence obesity in young people. The research findings are conflicting: in some studies, green spaces have shown a protective association with obesity and urbanization has turned out to worsen this condition, while other studies contradicted these results. The aim of the study was to examine the relationships between greenness, urbanization, and weight status among Italian adolescents. Student data (11-13 years old) on weight and height, physical activity (PA), and demographic characteristics were extracted from the 2018 Health Behaviour in School-aged Children (HBSC) survey in Piedmont, Northwest of Italy. Data on Normalized Difference Vegetation Index (NDVI) and urbanization were obtained from satellite images and the National Institute of Statistics (ISTAT). A multilevel regression model was used to assess the association between NDVI, urbanization, and obesity, controlling for PA. Students living in greener areas reported a lower likelihood of being obese [OR = 0.11, 95% CI 0.02-0.56, = 0.007], while students living in areas with a higher level of urbanization showed a significantly increased risk of obesity [OR = 2.3, 95% CI:1.14-4.6, = 0.02]. Living surrounded by higher amounts of greenness and lower levels of urbanization may positively influence health status through lower risk of obesity among youth.
最近的研究探讨了环境如何影响年轻人的肥胖问题。研究结果存在冲突：在一些研究中，绿地与肥胖呈保护相关性，而城市化则使这种情况恶化，而其他研究则与这些结果相矛盾。本研究旨在探讨意大利青少年的绿色环境、城市化与体重状况之间的关系。学生的体重和身高、身体活动 (PA) 和人口统计学特征的数据从意大利西北部皮埃蒙特的 2018 年“青少年健康行为调查”(HBSC)中提取。归一化植被指数 (NDVI) 和城市化的数据来自卫星图像和国家统计局 (ISTAT)。使用多水平回归模型来评估 NDVI、城市化与肥胖之间的关联，同时控制身体活动。生活在绿化较好地区的学生肥胖的可能性较低[OR = 0.11, 95% CI 0.02-0.56, = 0.007]，而生活在城市化水平较高地区的学生肥胖的风险显著增加[OR = 2.3, 95% CI:1.14-4.6, = 0.02]。生活在绿化程度较高、城市化程度较低的环境中可能会通过降低青少年肥胖的风险，对健康状况产生积极影响。
