摘要

目的:长期暴露于环境空气污染会增加老年人死亡率的证据仍然很少,特别是那些居住在低水平空气污染地区的老年人。本研究调查了中国老年人长期暴露于低水平空气污染与死亡率之间的潜在联系。方法:2018年至2020年,在中国深圳进行了一项基于人群的研究,共有317,464名年龄≥65岁的个体。使用逻辑回归模型来分析长期暴露于空气污染与全因死亡率(作为主要结果)以及非意外、癌症和心血管死亡率之间的关系。结果:发现了PM 1、PM 2.5、PM 10、so2、CO和o3暴露与全因死亡风险较高的显著关联。每增加1µg/ m3, PM 1的调整优势比(OR)分别为1.49[95%可信区间(CI): 1.46, 1.53], PM 2.5的调整优势比为1.30 (1.27,1.32),PM 10的调整优势比为1.05 (1.04,1.06),so2的调整优势比为5.84 (5.39,6.32),CO的调整优势比为1.04 (1.04,1.05),o2的调整优势比为1.02(1.00,1.03)。长期暴露在PM 1、PM 2.5、PM 10、so2和CO环境中也会增加非意外、癌症和心血管疾病死亡的风险。结论:长期低水平空气污染暴露与中国老年人死亡风险增加有关。

Long-Term Exposure to Low-Level Ambient Air Pollution and Mortality among 0.3 Million Chinese Older Adults.

Objective: Evidence that long-term exposure to ambient air pollution increases mortality among older adults, particularly those residing in low-level air pollution locations, remains scarce. This study investigated the potential links between long-term low-level air pollution exposure and mortality among Chinese older adults.

Methods: A population-based study with 317,464 individuals aged ≥ 65 years was conducted in Shenzhen, China during 2018 and 2020. Logistic regression models were used to analyze the associations between long-term exposure to air pollution and all-cause mortality, as the primary outcome, as well as non-accidental, cancer and cardiovascular mortality.

Results: Significant associations of PM 1, PM 2.5, PM 10, SO 2, CO, and O 3 exposures with a higher risk of all-cause mortality were found. Adjusted odds ratio ( OR) for each 1 µg/m 3 increment was 1.49 [95% confidence interval ( CI): 1.46, 1.53] for PM 1, 1.30 (1.27, 1.32) for PM 2.5, 1.05 (1.04, 1.06) for PM 10, 5.84 (5.39, 6.32) for SO 2, 1.04 (1.04, 1.05) for CO, and 1.02 (1.00, 1.03) for O 3, respectively. Long-term PM 1, PM 2.5, PM 10, SO 2, and CO exposures also elevated the risks of non-accidental, cancer and cardiovascular mortality.

Conclusion: Long-term low-level air pollution exposure was associated with an increased mortality risk among Chinese older adults.
