我们在多个国家或地区评价了空气动力学直径≤10 μm（PM10）的可吸入颗粒物（PM）和空气动力学直径≤2.5 μm的细颗粒物（PM2.5）与每日全因死亡率、心血管疾病死亡率和呼吸系统疾病死亡率之间的关联。我们从24个国家或地区收集了652个城市的每日死亡率和空气污染数据。并使用过度离散广义可加模型和随机效应荟萃分析方法研究了这些关联。我们拟合了双污染物模型，用于检验关联的稳健性。并且将各城市的浓度-反应曲线汇总，用于计算全球估计值。
平均而言，PM10浓度的2天移动均值（代表当天和前一天的平均值）增加10 μg/m3，相关每日全因死亡率、心血管疾病死亡率和呼吸系统疾病死亡率分别增加0.44%（95%置信区间[CI]，0.39%～0.50%）、0.36%（95% CI，0.30%～0.43%）和0.47%（95% CI，0.35%～0.58%）。PM2.5浓度发生相同变化时，每日死亡率的相应增幅分别为0.68%（95% CI，0.59%～0.77%）、0.55%（95% CI，0.45%～0.66%）和0.74%（95% CI，0.53%～0.95%）。对气态污染物校正后，上述关联仍然显著。在年平均PM浓度较低和年平均温度较高的地区，上述关联较强。汇总浓度-反应曲线表明，每日死亡率始终随着PM浓度的增加而增加，且PM浓度较低时的斜率较大。
