| Abstract |
Limited evidence is available regarding the long-term effects of fine particulate (PM ) air pollution on hypertension in developing countries. This study aimed to explore the associations of long-term exposure to PM with hypertension prevalence and blood pressure (BP) in China. We conducted a cross-sectional study based on a nationally representative survey (13,975 participants). We estimated the long-term average exposure to PM for all subjects during the study period (June 2011 to March 2012) by a satellite-based model with a spatial resolution of 10×10km. We applied multivariable logistic regression models to evaluate the associations between PM and hypertension prevalence and linear regression models for the associations between PM and systolic BP and diastolic BP. We also explored potential effect modification by stratification analyses. There were 5715 cases of hypertension, accounting for 40.9% of the study population in this analysis. The annual mean exposure to PM for all participants was 72.8µg/m on average. An interquartile range increase (IQR, 41.7µg/m ) in PM was associated with higher prevalence of hypertension with an odds ratio of 1.11 [95% confidence interval (CI): 1.05, 1.17]. Systolic BP increased by 0.60mmHg (95% CI: 0.05, 1.15) per an IQR increase in PM . The effects of PM on hypertension prevalence were stronger among middle-aged, obese and urban participants. This national study indicated that long-term exposure to PM was associated with increased prevalence of hypertension and slightly higher systolic BP in China. |
