Bo Y, et al. - Researchers examined a large longitudinal cohort for the impact of dynamic changes in long-term exposure to ambient particulate matter (PM_2.5) on incidence of hypertension. They performed a series of standard medical examinations, including blood pressure measurements, in 134,978 adults (aged 18 years or above). Using a satellite-based spatiotemporal model at a high resolution (1×1 km²), they determined the PM_2.5 concentration. They noted a decreased incidence of hypertension with an improvement in PM_2.5exposure, suggesting the efficacy of air pollution mitigation as a strategy to reduce the risk of cardiovascular disease. A 16% change in the incidence of hypertension was linked to every 5 µg/m3 change in exposure to PM_2.5.
