| 中文摘要 | 先前的研究已經顯示，使用三類暴露指標（綠地覆蓋、綠度和綠地景觀指數）對自殺具有預防效果。然而，大多數研究都是單獨使用每個指標的單階段方法，代表短期暴露。本研究使用2000年至2018年的長期數據，分層調查了三類暴露指標與自殺之間的關聯。綠度暴露使用了歸一化植被指數（NDVI），而景觀指數則選擇了均勻斑塊面積（面積和邊緣）、面積加權均值分形維度指數（形狀）和接近指數（接近度）。使用廣義加法混合模型，我們揭示了綠地覆蓋、NDVI、均勻斑塊面積、面積加權均值分形維度指數和接近指數的相對風險（95%置信區間）分別為0.998（0.997, 0.999）、0.860（0.811, 0.912）、0.999（0.999, 0.999）、1.485（1.056, 2.088）和0.999（0.999, 0.999）。這表明長期暴露於綠地覆蓋和綠度與自殺率降低相關。類似地，長期暴露於更大、形狀更簡單、距離更近的綠地也與自殺風險降低相關。在制定未來植樹政策時，除了增加綠地面積，還應考慮綠地的布局和連通性。本研究不僅顯示了長期暴露於綠地對降低自殺率的重要性，還展示了一種分層方法來檢查綠地的影響。 |
| 英文摘要 | Previous studies have demonstrated the preventive effects of greenness and greenspace using three classes of exposure metrics (greenspace coverage, greenness, and landscape indices for greenspace) on suicide. Nevertheless, most studies were individually employed for each metric using a single-phase method, representing the short-term exposure. We hierarchically investigated the association between three classes of exposure metrics and suicide using long-term data from 2000 to 2018 in Taiwan. Normalized difference vegetation index (NDVI) was used to represent the greenness exposure, while mean patch area (area and edge), area-weighted mean fractal dimension index (shape), and proximity index (proximity) were opted to represent landscape indices for greenspace. Using the generalized additive mixed model, we revealed that the relative risk (95% confidence interval) of greenspace coverage, NDVI, mean patch area, area-weighted mean fractal dimension index, and proximity index was 0.998 (0.997, 0.999), 0.860 (0.811, 0.912), 0.999 (0.999, 0.999), 1.485 (1.056, 2.088), and 0.999 (0.999, 0.999), respectively. This indicates that long-term exposure to both greenspace coverage and greenness is associated with a reduced suicide ratio. Similarly, long-term exposure to greenspace that is greater in size, simpler in shape, and closer in proximity is associated with a decreased suicide risk. For formulating future afforestation policies, the layout and connectivity of greenspaces should be considered besides increasing green areas. This study not only demonstrated the significance of long-term exposure to greenspace for reducing the suicide ratio, but also illustrated a hierarchical approach to examine the effects of greenspace. |
