Abstract:
Objective To investigate the exposure-response relationships and lag effects between air pollutants (PM2.5, PM10, O3, and NO2) and mortality in Jiading District, Shanghai, and to provide a scientific basis for the formulation of environmental health policies. Methods Using an individual-level time-stratified case-crossover design, conditional logistic regression models in conjunction with a distributed lag nonlinear model (DLNM) were employed to analyze the exposure-response relationship and temporal lag patterns of ambient air pollution on resident mortality in Jiading District (1994–2024). Results A total of 59 048 death cases were collected, including 18,701 deaths from cardiovascular diseases and 11 731 deaths from respiratory diseases. PM2.5 and NO2 had a significant impact on all-cause mortality, cardiovascular disease mortality, and respiratory disease mortality, with the most significant effects observed within a lag of 0–3 days. PM10 also had some impact on these three types of mortality, but its effect was generally weaker than that of PM2.5 and NO2. The exposure-response curves showed that the risk of death increased rapidly with increasing concentrations of PM2.5 and PM10, while the effect of NO2 plateaued at higher levels. No significant differences were found across age or gender subgroups. Conclusion Short-term exposure to PM2.5, PM10, and NO2 significantly increases all-cause mortality risk in Jiading District, with effects persisting up to 7 days, highlighting the need for enhanced air pollution control measures, particularly targeting fine particulate matter.
