Hypertension and Fine particulate matter
pollution in Delhi 

  • Strong effects of fine particulate matter exposure on blood pressure (BP) as well as risk of developing hypertension.

​

  • Observed higher average systolic BP in monthly and annual exposures.

​​

  • Positive but less pronounced associations were observed for diastolic blood pressure.

​

  • Average PM2.5 over durations of 1 year, 1.5 years, and 2 years increased the risk of developing hypertension by 1.5× (50% higher risk) 1.6× (60% higher risk), and 1.2× (20% higher risk), respectively.

​​

  • Results were stronger in study participants with higher waist-to-hip ratios, which is an indicator of central obesity.
