Abstract
The gender-based differences in the vulnerability to ambient air pollution have not been widely explored. This study aimed to investigate vulnerability differences to the short-term effects of PM<sub>2.5</sub>, PM<sub>10</sub> and O<sub>3</sub> between cerebrovascular diseases (CEVD) deaths of men and women. The general additive models (GAMs) and distributed lag non-linear models (DLNMs) were adopted, and both single-pollutant and two-pollutant models were performed to analyze the associations between ambient air pollution and daily CEVD deaths. Both models indicated that O<sub>3</sub> was the most suspicious pollutant that could induce excess CEVD deaths, and women tended to be more vulnerable to O<sub>3</sub>. These results were confirmed by seasonal analysis, in which we also found both genders were more vulnerable to O<sub>3</sub> in winter. The exposure-response relationships revealed that women were usually more vulnerable to ambient air pollution than men, and the exposure-response curves differed significantly between genders. Our findings suggested that more attention should be paid on the adverse effects of ambient O<sub>3</sub>, and the protection of women CEVD population against air pollution should be emphasized.
