Scientists from Sun Yat-sen University (SYSU) and Guangdong Provincial Center for Disease Control and Prevention (GDCDC) published their collaborative research on Hypertension, a journal of American Heart Association (AHA) on May 31 (“Associations of Short-Term and Long-Term Exposure to Ambient Air Pollutants With Hypertension A Systematic Review and Meta-Analysis”), which provided strong evidence supporting the links between air pollution and high blood pressure. The co-first authors are Cai Yuanyuan, a master candidate and her supervisor Zhang Bo, an associate professor in School of Public Health, SYSU, and the corresponding authors are Ma Wen-jun and Liu Tao from GDCDC.

The authors summarized the 17 epidemiological studies published before September 1, 2015 and performed a meta-analysis to investigate the associations of short-term and long-term exposure to ambient air pollutants with hypertension. The pooled results showed that short-term exposure to SO2 (OR=1.046, 95% CI: 1.012–1.081), PM2.5(OR=1.069, 95% CI: 1.003–1.141), and PM10(OR=1.024,95% CI: 1.016–1.032) were significantly associated with hypertension. Long-term exposure (a 10 μg/m3 increase) to NO2(OR=1.034, 95% CI: 1.005–1.063) and PM10(OR=1.054, 95% CI: 1.036–1.072) had significant associations with hypertension.

AHA published a rapid access journal report on May 31, accompanying this paper. Time, Reuters, Medical Research, Health day, Daily Science, Eurekalert and Medical Express interviewed the authors by E-mail and reported the research.

This work was supported by the National Natural Science Foundation of China, Natural Science Foundation of Guangdong Province, Fundamental Research Funds for the Central Universities, and Postdoctoral Science Foundation of China.

Both Ma Wen-Jun and Liu Tao are alumni of SYSU, who entered into School of Public Health, SYSU in 1987 and 2001, respectively.
