This research investigates how social vulnerability levels influence the relationship between PM2.5 exposure and mortality due to circulatory and respiratory diseases.
Conducted an ecological time-series study from 2010 to 2023
Analyzed monthly death data from 63 Primary Health Care Centers
Stratified health data into four vulnerability groups
Used distributed lag non-linear models within a generalized additive modeling framework, adjusting for various factors
A total of 38,311 cardiorespiratory deaths were recorded during the study period
Significant positive association between PM2.5 and mortality observed only in the intermediate-high vulnerability group
No significant associations found in the lowest or highest vulnerability strata
Mortality rates varied non-linearly with PM2.5 concentrations

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Ecological time-series study finds PM2.5 exposure affects mortality differently by social vulnerability levels, suggesting targeted health strategies.
