Long-Term Ozone Exposure Linked to Increased Risk of Chronic Kidney Disease Mortality, reveals study

The key findings of the study were:

• In both single and two-pollutant models, long-term ozone exposure was significantly associated with an increased risk of ESRD and all-cause mortality.

• The hazard ratios (HR) for ozone exposure varied depending on the assessment method, with HR values of 1.025 (95% CI: 1.014–1.035) at the district level and 1.04 (95% CI: 1.035–1.045) at the individual address level for ESRD risk.

• Similarly, HR values for all-cause mortality were 1.012 (95% CI: 1.008–1.017) at the district level and 1.04 (95% CI: 1.031–1.05) at the individual address level.

This study provides compelling evidence that long-term ambient ozone exposure increases the risk of end-stage renal disease and mortality in individuals with chronic kidney disease. The findings underscore the importance of implementing strategies to reduce ozone emissions, which would not only benefit public health but also contribute to environmental preservation. Efforts to mitigate ozone pollution are essential in safeguarding the health of vulnerable populations and promoting overall well-being.
