Gender differences rooted in anatomy
When asked for an explanation of the difference in the impact of pollution on mortality between men and women, Dr. Swieczkowski explained that women are likely more vulnerable because of differences in anatomy of the pharynx and larynx, and breathing patterns. Previous studies have shown that air pollution causes more oxidative stress in women. Also, in the current study, the mean age of the women was 8 to 9 years older, he said.
The study design was an “elegant way to take away the impact of other cardiovascular risk factors,” noted session moderator Maryam Kavousi, MD, of Erasmus University Medical Center, Rotterdam, the Netherlands.
The study was supported by the National Science Centre, Poland. The researchers had no financial conflicts to disclose.
