Green spaces have been shown to be beneficial to humans, but quantifying these benefits is a challenge for epidemiology. In this health impact assessment study, we exploit satellites to estimate for the whole of Italy the number of deaths that could be prevented in the 49 million adult population by greening residential areas. The exposure was assessed by calculating the normalized difference vegetation index at 10-m resolution within a 300-m distance from homes in 7904 municipalities. In this study we estimate, by achieving nationwide the level of residential greenness currently reached by the 25% of the population, a total of 28,433 (95% confidence interval: 21,400-42,350) preventable deaths and 279,324 (210,247-415,980) preventable years of life lost in Italy in 2022, representing the 5% of the total mortality burden. More green means fewer deaths, thus strong action is needed to increase the amount and accessibility of green spaces in all human settlements.
已有研究表明，绿地对人类有益，但量化这些益处对流行病学来说是一项挑战。在这项健康影响评估研究中，我们利用卫星估算了在意大利全国范围内，通过绿化居民区，4900万成年人口中可预防的死亡人数。通过计算7904个市镇中距离住宅300米范围内10米分辨率的归一化植被指数来评估暴露情况。在本研究中，我们估计，如果在全国范围内实现目前25%的人口所达到的住宅绿化水平，2022年意大利总共可预防28433例死亡（95%置信区间：21400 - 42350），以及279324例（210247 - 415980）可预防的生命年损失，占总死亡负担的5%。绿化程度越高意味着死亡人数越少，因此需要采取有力行动，增加所有人类住区的绿地数量和可达性。
