Abstract：Objective To explore the relationship between atmospheric particulate matters (including PM2.5 and PM10) and cardiovascular and cerebrovascular diseases in Urumqi City. Methods We collected the data about atmospheric pollutants, meteorological factors and hospitalizations for cardiovascular and cerebrovascular diseases in Urumqi from 2019 to 2021, analyzed the risk effects of short-term exposure to atmospheric particulate matters on hospitalizations for cardiovascular and cerebrovascular diseases based on the distributed lag non-linear model (DLNM). Subgroup analysis was also performed for age, sex, and season. Results There was a significant association between atmospheric particulate matters and hospitalizations for cardiovascular and cerebrovascular diseases. The relative risk of hospitalizations for cardiovascular and cerebrovascular diseases was 1.115 (1.065-1.167) for the whole population, 1.130 (1.077-1.186) for males and 1.123 (1.071-1.178) for people aged < 65 years when the cumulative lag was 7 days for every 10 μg/m3 increase in the PM2.5 concentration. The relative risk of hospitalizations for cardiovascular and cerebrovascular diseases was 1.005 (1.000-1.009) for the whole population, 1.006 (1.001-1.011) for males and 1.005 (1.004-1.010) for people aged < 65 years when the lag was 1 day for every 10 μg/m3 increase in the PM10 concentration. The maximum effect values of PM2.5 and PM10 on hospitalizations for cardiovascular and cerebrovascular diseases in winter were 1.018 (1.006-1.032) and 1.004 (1.000-1.009) respectively. Conclusion Short-term exposure to PM2.5 and PM10 can increase the risk of hospitalizations for cardiovascular and cerebrovascular diseases. Hence we should focus on the prevention and treatment of atmospheric particulate matters and pay attention to the health care of sensitive people and special seasons.
