Air pollution is known to have notable negative effects on human health. Recently, the effect of air blood pressure among elderly has attracted researchers' attention. However, existing evidence not consistent, given that positive, null, and outcomes are presented in literature. In this study, we investigated relationship between (BP) indices pollutants (PM2.5, PM10, quality index) a specific population through panel study address knowledge gap.We obtained repeated BP measurements from January 2017 May 2019 619 with total 5106 records Nanjing, China. Data daily ambient pollutants, including fine particulate matter an aerodynamic diameter ≤ 2.5 μ m (PM2.5), 10 (PM10), index (AQI) same period were obtained. We evaluated association average concentrations past one-week, two-week, four-week lags before measuring BP. The non-linear regression models used fixed- mixed-effects control age, gender, temperature.In fixed-effects model, concentration PM2.5 significantly associated systolic (SBP) at all but only correlated diastolic (DBP) one-week lag. An interquartile range (IQR) increase moving (38.86 μg/m3) our sample increases SBP DBP by 7.68% 6.9%, respectively. PM10 shows pattern as PM2.5. AQI less significant associations no one- two-week lags. lag.Exposures (PM2.5 PM10) increased older people, indicating potential link high prevalence hypertension. well-recognized risk factor for future cardiovascular diseases should be reduced prevent hypertension elderly.
