石家庄市大气颗粒物对居民循环系统疾病死亡的寿命损失年影响的研究

目的 探讨石家庄市大气颗粒物(PM₁₀、PM_2.5 )对居民每日循环系统疾病死亡和寿命损失年(YLL)的影响。方法收集石家庄市2018年1月1日—2021年12月31日的每日大气颗粒物、气象资料及循环系统死亡数据，计算每日YLL值，利用广义相加模型评估大气颗粒物对居民每日循环系统疾病死亡和YLL的影响。结果 研究期间，石家庄市PM₁₀、PM_2.5 浓度每升高10μg/m3对每日循环系统疾病死亡的效应最大值分别出现在lag02、lag0，分别为0.37%(95%CI:0.09%～0.64%)、0.61%(95%CI:0.18%～1.04%)。PM₁₀、PM_2.5 每升高10μg/m3，分别导致每日YLL增加1.07年(95%CI:0.06～2.09)、1.73年(95%CI:0.15～3.32)。双污染物模型中，PM10及PM_2.5 均具有独立的健康效应。性别分层结果显示，PM₁₀、PM_2.5...

A study on the effect of atmospheric particulate matter on life lost years of death from circulatory diseases in Shijiazhuang

Objective To investigate the effect of atmospheric particulate matter on daily circulatory disease mortality and years of life lost (YLL) in Shijiazhuang city. Methods The daily atmospheric particulate matter monitoring data, meteorological information, and daily mortality data of circulatory system in Shijiazhuang from January 1, 2018 to December 31, 2021 were collected. The daily YLL value was calculated, and the generalized additive model was used to evaluate the effects of atmospheric particulates on daily circulatory disease mortality and YLL of residents. Results During the period, the maximum effect of each 10μg/m3 increase in PM10 and PM2.5 concentration on daily circulatory mortality was found in lag02 and lag0, which were 0.37% (95%CI: 0.09%-0.64%) and 0.61% (95%CI: 0.18%-1.04%), respectively. Each 10μg/m3 increase in PM10 and PM2.5 resulted in 1.07 years (95%CI: 0.06-2.09) and 1.73 years (95%CI: 0.15-3.32) increase in daily YLL. In the dual-pollutant model, both PM10 and PM2.5 showed independent health effects. The results of gender stratification showed that each 10μg/m3 increase in PM10 and PM2.5 concentrations had a greater impact on daily circulatory disease deaths in men and women. Age-stratified results showed that each 10μg/m3 increase in PM10 and PM2.5 had a greater impact on daily circulatory disease deaths in residents aged ≥60 years. Each 10μg/m3 increase in PM2.5 concentration had a greater impact on the daily YLL of residents aged ≥60 years. Conclusion Atmospheric particulate matter in Shijiazhuang can contribute to the increase of daily circulatory disease deaths and daily YLL. PM2.5 has stronger health effects on residents than PM10, and residents ≥60 years old are more susceptible to particulate matter effects.
