Diabetes mellitus is a global public health concern, yet its association with neighborhood green space remains unexplored at a national scale in Brazil. This study analyzed the relationship between green space, measured via the Normalized Difference Vegetation Index (NDVI), and diabetes-related hospitalizations from 2008 to 2018. Using quasi-Poisson regression models, we assessed hospitalization data by sex and age group, incorporating air pollution, weather, and socioeconomic factors as covariates. Results showed regional variations: increased greenness was linked to lower hospitalizations in the North and Midwest, while the Northeast and Southeast exhibited higher hospitalization rates with increased NDVI. The South had mixed results, with positive associations for men and middle-aged individuals. Findings suggest that green spaces may have a protective effect in some regions but require further investigation in others. These results underscore the need for targeted urban planning and public health strategies to optimize green space benefits.
糖尿病是一个全球公共卫生问题，但在巴西全国范围内，其与邻里绿地的关联仍未得到探索。本研究分析了通过归一化植被指数（NDVI）衡量的绿地与2008年至2018年糖尿病相关住院情况之间的关系。我们使用准泊松回归模型，按性别和年龄组评估住院数据，并将空气污染、天气和社会经济因素作为协变量纳入分析。结果显示出区域差异：绿地增加与北部和中西部地区住院率降低相关，而东北部和东南部地区随着NDVI增加，住院率更高。南部地区结果不一，男性和中年个体呈现正相关。研究结果表明，绿地在某些地区可能具有保护作用，但在其他地区则需要进一步研究。这些结果强调了制定有针对性的城市规划和公共卫生策略以优化绿地效益的必要性。
